    Description / Table of Contents: Zusammenfassung Simulation von Störungen zweiter Ordnung im Computer Störungen zweiter Ordnung lassen sich mit einer bisher noch nicht gekannten Genauigkeit mit Hilfe einer von Malina (1969, 1970) entwickelten Programmversion der Finite-Element-Methode im Computer simulieren. Die Rechnungen zeigen, daß mit einer Scherbewegung entlang der Hauptstörung und dem Weiterreißen der Störung Spannungsumlagerungen einhergehen, die mitbewirken, daß neue sekundäre Störungen entstehen. Die ermittelten Störungen zweiter Ordnung lassen sich nach der Klassifikation von Chinnery (1966) als die ScherflächentypenA, B, E undF einordnen. Darüberhinaus liefert die Rechnung zwei sehr häufig auftretende Scherflächen, die sich nach Chinnery nicht klassifizieren lassen.
    Abstract: Résumé Simulation de failles de deuxième ordre par l'ordinateur Les failles de deuxième ordre peuvent être simulées avec une précision encore jamais atteinte grâce à l'utilisation d'une version d'une programme développé par Malina (1969, 1970) à partir de la méthode des éléments finis. Le calcul montre que, conjointement au cisaillement le long de la faille principale et à la propagation de cette faille, de nouvelles redistributions des contraintes apparaissent. Ces nouvelles redistributions contribuent essentiellement au développement de nouvelles surfaces de failles secondaires. Les failles de deuxième ordre peuvent être classées d'après Chinnery (1966) suivant les catégories de surfaces de cisaillementA, B, E, etF. De plus, le calcul indique fréquemment deux autres types de surfaces de cisaillement n'entrant pas dans la classification de Chinnery.
    Notes: Summary Computer Simulation of Second Order Faults Faults of the second order can be simulated in the computer with an accuracy hitherto unknown, by using Malina's (1969, 1970) program version of the Finite Element Method. The computations show that stress rearrangements occur with shear movements along the principal fault and with propagation of the fault. These stress rearrangements contribute to the development of new secondary faults. The computed second order faults can be classified according to Chinnery (1966) as shear plane typesA, B, E, andF. Moreover, the computation shows two dominant shear planes which cannot be classified according to Chinnery.

    Description / Table of Contents: Zusammenfassung Das mechanische Verhalten von vorgebrochenen Gesteinsproben unter Druckbelastung Der vorliegende Aufsatz beschreibt die Ergebnisse von Druckversuchen, die an vorgebrochenen Gesteinsproben durchgeführt worden sind. Proben von Westerly Granit und Cedar City Tonalit wurden zunächst in steifen Kammern vorgebrochen und anschließend in Triaxialversuchen bis zu 7 kb Manteldruck belastet. Die Ergebnisse weisen interessante Charakteristiken auf, besonders die Beibehaltung erheblicher Festigkeitswerte bei verschiedensten Belastungszuständen sowie die Zunahme der größten Verformung. Die erhaltenen Daten werden mit Ergebnissen von Reibungsversuchen an Westerly Granit, die aus der Literatur bekannt sind, verglichen. Die weitgehende Übereinstimmung der größten Spannungswerte läßt darauf schließen, daß Reibung das mechanische Verhalten vorgebrochener Proben wesentlich beeinflußt.
    Abstract: Résumé Comportement mécanique en compression de la roche pré-fracturée Cet article décrit les procédés expérimentaux et les résultats obtenus à la suite d'une étude expérimentale sur des échantillons de roche fracturés à l'avance. Dans ces essais, des échantillons de granite W et de tonalité CC ont été brisés dans des appareils spéciaux et soumis ensuite à l'essai triaxial. Des pressions latérales jusqu'à 7 kbar ont été employées. Les échantillons de roche avaient été largement fragmentés pendant la fracturation initiale. Les résultats indiquent un certain nombre de particularités intéressantes, y compris le maintien significatif d'une aptitude à supporter des charges sous maintes conditions de contraintes, et une augmentation de la déformation maximale. On a fait une comparaison avec les résultats de frottement obtenus ailleurs pour le granite W. Le bon accord des contraintes maximales suggère l'importance du frottement dans le comportement mécanique des échantillons.
    Notes: Summary The Mechanical Response of Pre-Fractured Rock in Compression This paper describes experimental procedures and results obtained from an experimental study of pre-cracked rock specimens. In these experiments specimens of Westerly granite and Cedar City tonalite were broken in special fixtures and subsequently retested in a triaxial apparatus. Confining pressures up to 7 kb were employed. The rock specimens were well fragmented during the pre-cracking process. The results indicate a number of interesting features, including the significant retention of load-carrying ability under many stress conditions and an increase in maximum deformation. A comparison is made with frictional data determined elsewhere for Westerly granite; the close agreement in maximum stress suggests the importance of friction in the specimen mechanical behavior.

    Notes: Résumé Cette recherche a été entreprise pour vérifier la validité d'une nouvelle méthode de mesure des déformations relatives internes, dans des ouvrages en béton déjà construits. Le principe de la méthode consiste à forer, dans l'ouvrage, un trou, puis à le reboucher par scellement d'une carotte à l'intérieur de laquelle ont été placés des extensomètres. La méthode est basée sur un étalonnage préalable, qui permet d'obtenir des coefficients de corrélation entre une solution monolithe et une solution carottée. C'est cet étalonnage qui est exposé tout au long de cette étude. En dehors des régions où les sollicitations sont complexes, cette méthode permet d'obtenir de précieux renseignements sur le comportement mécanique de l'ouvrage. Elle a été employée sur un grand chantier de la région parisienne, et les résultats obtenus sont très satisfaisants.

    Description / Table of Contents: Résumé Etats possibles du chlorure au cours de l'hydratation du silicate tricalcique en présence de chlorure de calcium.— L'hydratation du silicate tricalcique en présence de chlorure de calcium s'accompagne de réactions endo et exothermiques qu'on n'observe pas dans d'autres circonstances. La réaction endothermique, qui se produit entre 550 et 590 °C est attribuée à la formation d'une couche de chlorure à la surface du silicate lors de l'avant-prise. Une intense réaction exothermique, apparaissant entre 640 et 690 °C coïncide avec une période d'hydratation accélérée et est attribuée à la sorptioncombinaison de chlorure sur le silicate et à la présence de chlorure dans les couches de structure. On peut obtenir cette réaction exothermique en faisant agir CaCl2 sur le silicate tricalcique à tout moment de l'hydratation. L'analyse thermique différentielle continue sous vide permet d'éliminer le pic exothermique, excepté lorsque l'expérience se fait dans un courant d'azote. L'endotherme obtenu durant l'avant-prise et le pic exothermique formé lors de la période d'accélération peuvent être éliminés par lavage à l'eau des éprouvettes. On peut extraire à l'alcool environ 13 % du chlorure ajouté durant quatre heures d'hydratation, mais après sept jours, le chlorure n'est pratiquement plus extrait. Les valeurs correspondantes pour l'extraction à l'eau sont de 86 et de 78 %. Il est supposé que le chlorure de calcium existe sous quatre ou cinq formes différentes, même complexes, lors de l'hydratation du silicate tricalcique, selon sa proportion et la durée de l'hydratation. Il y a présence de CaCl2 libre dans les premiers temps de l'hydratation. Durant l'avant-prise, le chlorure est adsorbé aussi à la surface du silicate tricalcique. Au cours de la période d'accélération, et après le chlorure est adsorbé sur les silicates hydratés produits, et en partie sur les couches de structure. Ultérieurement une quantité importante de chlorure s'incorpore intimement aux formations de silicates hydratés et ne peut être extraite à l'eau. En fonction de la durée d'hydratation et des formes diverses de chlorure, il est possible qu'une action s'exerce sur: l'avant-prise, le temps de prise, l'accélération, la surface développée, le retrait, le rapport CaO/SiO2 du silicate hydraté produit, la morphologie et la résistance.
    Notes: Abstract Calcium chloride may be present in the free, adsorbed or interlayer state in hydrating tricalcium silicate. Attempts have been made to study these states to correlate some of the physical, chemical and mechanical properties.

    Notes: Abstract A systematic presentation of arrangements and materials for detection of reinforced concrete by means of gamma-radiography is the first aim of this paper. New proposals concerning auxiliary techniques in gamma-radiography have been investigated: a) Photometric measurements on simple gamma-radiographies have been applied, in order to estimate the diameter of an embedded bar, on the basis of the difference in film density, between the image of the bar and its surrounding area. b) Ordinary photogrammetric apparatuses have been used on twin stereo-radiographies for direct discrimination of complicated bars of concrete reinforcements. The same method has been applied for a direct reading of the position and diameter of every bar simultaneously, instead of repetitive application of two-equations systems for each bar in conventional stereo-radiography.

    Notes: Résumé Cet article expose les possibilités de mesure «in situ» de l'humidité des matériaux, par une méthode diélectrique, au moyen de sondes noyées dans le matériau ou placées en contact intime avec lui. Les mesures sont effectuées, à travers un câble coaxial, par un pont de mesure qui fournit les deux composantes de l'admittance. On décrit les sondes et l'appareillage utilisés, ainsi que la méthode d'interprétation, basée sur la loi des indices, qui permet de séparer les deux facteurs importants: teneur en eau et conduction de l'eau. On donne des exemples d'application à différents problèmes: séchage, mesures à température variable, évolution des propriétés d'un matériau confiné.

    Description / Table of Contents: Résumé Facteurs qui affectent les propriétés des unités de construction mécaniquement formées.—On a obtenu par façonnage mécanique sous pression des briquettes perforées à partir d'un mélange sélectionné de 70% d'argile et de 30% de sable. La désaération du mélange extrudé joue, un rôle important dans la diminution des pores et dans l'accroissement de la résistance des échantillons cuits. En outre, la désaération contribue à réduire les laminations que subit le produit au cours de l'extrusion. La désaération, ou le recorroyage sous vide du mélange extrudé, ont un effet marquant sur les propriétés dues au séchage et à la cuisson des briquettes, et contribuent à éliminer les défauts de formage et à améliorer les propriétés physiques requises. Par contre le précorroyage par passage du mélange entre deux cylindres, n'a pas d'effet sensible sur ces propriétés, quoiqu'il facilite nettement le pétrissage et le malaxage de l'argile. On a constaté que la résistance aux charges des échantillons cuits dépend principalement de la surface effective de chargement et de la direction de l'extrusion, comme de la dimension et de la forme des perforations que comportent les briquettes.
    Notes: Abstract The physical and mechanical properties of mechanically-pressed clay building units, whether solid or perforated, are largely improved by deairing. Die-laminations are lessened. Moreover, deairing provides always units of developed strengths. Prepugging, using birollers machinery, proves effective only in rubbing and well mixing the clay mixes before extrusion. In solid machine-pressed building units the direction of extrusion shows the relatively highest value when tested for strength. On the other hand, for the perforated equivalents, this depends, among other factors, on the load-bearing area to which the pressure is applied. However, the size and shape of perforations through the perforated units largely affect the mechanical properties of the latter.

    Notes: Summary and Conclusions This study examines the influence of the spatial structure of city locations on air travel by considering the factors of intervening opportunities and the hierarchical system of cities in addition to the simple dimension of distance. The statistical results show that the familiar strength of the gravity model is matched by that of the intervening opportunities model, but only when all cities are analyzed together. The disaggregation of cities by size and region (hierarchy) leads to a spotty performance by both models. The generality of the gravity and intervening opportunities models is thus called into question, and the potency of the hierarchical city organization as a contributing influence determining air traffic flows is demonstrated.

    Notes: Summary Several variables have been chosen which might reasonably be expected to explain the interstate migration which has occurred in India. The independent variables used in the study explain a fairly high percentage of the variance in migration between states, and all variables except Uj are significant at the 5 percent level or better. The distance variable consistently has in absolute value the highest elasticity in the various estimated relationships, and it is the variable which contributes most in terms of addition to R2. This result is similar to those of other studies dealing with both advanced and less-developed countries, but it appears that the deterring effects of distance may be greater in India than in other countries studied. Migration in India tends to be away from low-income states and toward high-income states, a finding which is similar to those for Ghana, Egypt, and Brazil. Migration also tends to be away from and to populous states, and while migration is away from highly urbanized states, it does not seem to be toward highly urbanized places in India,ceteris paribus. However, migration does tend to be in the direction of places which are urbanizing rapidly and away from places which are urbanizing slowly. There is evidence that in India mobility tends to increase with increased education; this finding is contrary to what was found for Ghana, Egypt, and Brazil. Migration in India also tends to be toward places which display relatively high levels of educational achievement.

    Notes: Conclusions The following conclusions may be drawn from the study: 1. It is possible to estimate the drawing power of stores through information on the origin of customers gathered in those stores. 2. The type of measures of distance decay which were estimated conform with Zipf's principle of least effort and as theorized by Huff's formulation of the standard gravity model. 3. Super market drawing power is affected by location. 4. A simplex algorithm for function fitting is an efficient and effective method of estimating the distance effect exponent. 5. It may be possible to use this technique to study the usage of other people-based activities and systems of activities.

    Notes: Conclusions The aim of these experiments was to discover whether some very simple modifications of the transportation model could be found to take advantage of the efficiency implications by shifting hospital capacities and to gain realism by recognizing some distance indifference and thereby increase significantly the number of paths taken. These experiments seem successful and the simple elegance of the transportation model preserved. We could have forced more paths to be taken by imposing capacity constraints on particular paths. This is reasonable in the case of shipments via scheduled carriers, such as airline movements, but not for our problem of patient visits to hospitals where there is no rational basis for adding capacity limits. In spite of the success of these experiments the programming approach as such may not be the most satisfactory. Indeed, a modified gravity model approach may better capture patient perception and behavior. Nevertheless, these programming modifications may serve to increase the range of applicability and the realism of results of the transportation model. By introducing variable distance perception we may look upon the modified solution as a fuller measure of optimum behavior rather than a departure from it.

    Notes: Conclusion A brief description of various socio-ecological models and their data requirements have been presented in this paper. It is evident that there is an enormous gap between the need for the data on the “quality of life” and the actual supply of such data. It has been argued that any model building effort in the area of ecological system must wait until an adequate data base is established. However, the identification of data requirements for the construction of such models points out the characteristics of statistical information system that should be established. As it has been pointed out by Hirsch, “Statistical agencies will drag their feet in the development of needed data if no guidelines for collection are provided” [Hirsch (6), p. vi]. The construction and interpretation of any social indicators should require more theoretical analysis as to the meaning of the measurement of such indicators and interrelationships among variables. Extensive theoretical as well as empirical work on submodels by different disciplines must precede any attempt to build a truly comprehensive socioecological model. However, the constant interaction among different disciplines to exchange information on their research findings and to discuss implications of such findings to other disciplines should be carried out simultaneously in order to understand the impact of human activities to environment.

    Notes: Conclusions Sizeable economies and diseconomies of size exist with regard to a given quality of police protection. Our results show that the per capita social cost of crime declines slowly with larger cities until a low point is reached in cities with a population ranging from 250, 000 to 500, 000. Social costs rise sharply for cities of over 1 million inhabitants. By and large, the smaller cities are able to reduce their crime rates with an increase in police numbers while the larger cities fail to do so based on evidence from time series analysis. Thus our results underestimate the social cost of crime in large cities even though they show the cost to be lower in small cities than in large cities. The results suggest that policies of decentralization rather than increasing police rates may be the most cost-effective long-run solution to high crime rates in large cities. Recommendation of a policy, however, awaits a more definitive analysis of costs of other services by city size.

    Notes: Conclusions Rapidly growing technology and experimentation in remote sensing occasion inquiries into the role of this tool in urban and regional information systems and decision making processes. Its primary efficacy lies in the substitution for current capabilities as contrasted to the rendering of entirely new services. Implementation of large scale urban and regional remote sensing systems must be preceded by careful analysis of the costs and benefits involved. Lack of good parametric data at this time precludes clear statements on benefit/ cost relationships. Nevertheless, access to a new technical capability should not divert attention from the major goal, i. e. the establishment of effective urban and regional management and decision making based on appropriate information and criteria. The largest roadblocks in comprehensive remote sensing relate to the interfacing of data collection and data reduction systems and the quality of data itself. Study of remote sensing in urban transportation supports the previous points. In the foreseeable future, it appears that monitoring and surveillance of the relatively static features of transportation and traffic promise more substantial pay-offs than analysis and real-time control in dynamic areas including travel behavior.

    Notes: Conclusions This analysis of the consumption function based on the income and expenditure accounts recently developed for Hawaii underscores the value of using appropriate data fin regional analysis. It shows that consumption functions developed at the national level can be successfully used at the regional level. The importance of the explanatory variables changes when one moves from the national aggregate to the regional components. In particular, the results obtained point out the effect of the region's growth rate and the origin of income on the level as well as the composition of consumption. To the extent that regional variations in these variables exist, national estimates of the coefficients of the consumption function are unreliable substitutes for regional coefficients. Although this warning is familiar to economists engaged in regional input-output studies, it has not been heeded by all those engaged in regional macroeconomics. The results reported, as well as their implications, strongly support the call by some regional economists for the development of “regional macroeconomics.”

    Notes: Conclusion Using the 1959–1969 Southeast-national growth rate differential as a case study, this paper has introduced a simple technique for examining the non-behavioral components of this growth rate differential. This technique disaggregates by income source the rate and weight effects of this differential. Its value is that it disaggregates, measures, and offers some conceptual insight into regional phenomena that actually occurred.

    Description / Table of Contents: Résumé On étudie les modules dynamiques et les caractéristiques d'amortissement de la pâte durcie, du mortier et des prismes de béton sollicités par des vibrations longitudinales, de flexion et de torsion aux fréquences fondamentales. On considère les effets sur les propriétés dynamiques des conditions de conservation, des rapports eau/ciment et agrégat/ciment, du type d'agrégat, du mode de vibration et de la présence d'inclusions rigides dans une matrice relativement molle. Les modules dynamiques des matériaux liants croissent avec le vieillissement et décroissent avec l'augmentation de la teneur en eau, mais le décrément logarithmique décroît avec le vieillissement et croît avec la teneur en eau. L'addition de sable à la pâte et de gros agrégat au mortier augmente les modules dynamiques mais diminue ensuite la capacité d'amortissement, la vitesse de variation dépendant de la teneur en eau et de la quantité et du type d'agrégat. Le séchage diminue à la fois le module dynamique et le décrément logarithmique, mais la variation du module élastique est beaucoup plus failble que celle de l'amortissement. La diminution est en partie un processus irréversible et généralement est plus faible pour le mortier que pour le béton. Les résultats montrent qu'il est douteux que les propriétés des liants puissent dépendre uniquement de leurs propriétés de résistance pour tous les composants. Les modules de résonance longitudinalement et en flexion sont pour les liants à peu près les mêmes dans les éprouvettes humides, tandis que le module de cisaillement est environ de 40 à 45% du module de Young correspondant. L'amortissement est plus fort en vibration longitudinale et moindre pour les vibrations de torsion. On montre que l'amortissement dans les matériaux liants dépend avant tout de la teneur en eau et qu'il résulte d'une combinaison complexe d'effets de viscosité, de frottement et de réactions de l'état solide. L'amortissement se produit surtout dans le mortier, en partie aux interfaces, et dans une moindre mesure dans l'agrégat. Les relations entre contrainte et déformation, module dynamique et résistance, entre amortissement et résistance à la compression, et entre le module dynamique et les propriétés des constituants sont examinées.
    Notes: Abstract The dynamic moduli and the damping properties of hardened paste, mortar matrix and concrete prisms excited in the fundamental longitudinal, flexural and torsional vibrations are presented. The effects on dynamic properties of curing conditions, water-cement and aggregate-cement ratios, the type of aggregate, mode of vibration and of the presence of rigid inclusions in a relatively soft matrix are investigated. The stress-strain behaviour and the mechanism of damping of cementitious materials are discussed. Relations between dynamic moduli and strength, between damping capacity and compressive strength, and between dynamic moduli and the properties of the constituents are presented.

    Notes: Abstract A simple theoretical approach is used to obtain expressions for the dependence of a number of physical properties of concrete upon the physical properties of its constituents and the aggregate volume concentration. It is assumed that concrete approximates to a two phase material consisting of aggregate particles dispersed in a cement matrix and it is shown that the theory is in reasonable agreement with some Young's modulus, creep and shrinkage measurements made on concrete.

    Notes: Summary The integral mean values of gravity on the surface W=W 0 , obtained from satellite observations with the use of harmonic coefficients[3, 7] and from terrestrial gravity measurements[12], are compared. The squares and products of the harmonic coefficients were neglected, with the exception of [J 2 (0) ] 2 , which was taken into account. The Potsdam correction and the geocentric constant are being discussed. The paper ties up with[13–15] and the symbols used are the same. The given problem was treated, e.g., in[2, 4, 6, 8–10]; in the present paper the values of gravity are compared directly.

    Notes: Zusammenfassung Es wurde versucht, mit Hilfe der piezophotographischen Methode das Druckfeld in der Nähe einer Untergrundsprengung zu untersuchen. Kugelförmige Ladungen von 5 kg TNT wurden 3 m unter die Oberfläche im konsolidierten Sandboden angebracht. Piezophotographische Druckaufnehmer mit Messbereich 1,5–250 bar und 15–2500 bar wurden sowohl statisch, als auch dynamisch geeicht und ihre Richtungscharakteristik bestimmt. Es wurden insgesamt 5 Druckfelduntersuchungen vorgenommen, wobei die Druckmessungen in einem orthogonalen Netz von Messpunkten, das sich bis in die Entfernung von 40 Ladungshalbmessern ausdehnte, durchgeführt wurden. Die entwickelte Messtechnik wird eingehend beschrieben. Auf Grund der erhaltenen Ergebnisse konnte unmittelbar für jeden Versuch die Druckverteilung in vertikalen und horizontalen Netzprofilen festgelegt werden. Das Druckfeld wurde danach durch den Isobarenverlauf in der untersuchten Ebene abgebildet.

    Notes: Zusammenfassung Als Grundlage der Arbeit dient das Verfahren, dem zufolge man eine unregelmässige Schwingung auf die Summe der Sinusschwingungen überführen kann. Man geht dabei vom Komplexspektrum der gegebenen Schwingung aus, von dem Spektren der Sinusschwingungen mit entsprechender Frequenz, Amplitude und Phase sukzessiv abgezogen werden. Die beschriebene Methode wurde in der vorliegenden Arbeit für magnetische und tellurische Pi2-Pulsationen angewendet. Man hat gefunden, dass die Pi2-Pulsationen aus 3–6 Schwingungen bestehen. Auf solche Weise entstand das Material für die magnetotellurische Sondierung. Die Ergebnisse schliessen gut an die Pc3-Pulsationen an. Der Hauptbeitrag des beschriebenen Verfahrens liegt darin, dass die Anzahl der Punkte zum Finden des spezifischen Widerstandes, und zwar in verschiedenen Perioden, erhöht wird.

    Notes: Summary Every electromagnetic seismograph provides a record in the high-frequency range proportional to the time integration of the ground displacement. An intentionally extending this part of the amplitude characteristic of the integrator can be achieved when the equivalent periods of the seismometer and galvanometer are equal by a suitable combination of the equivalent damping constants: for integrator A, D 1 =0.383 and D 2 =0.924, for integrator B, D 1 =D 2 =0.650. The partial constants required to carry this out are given in Tabs 1 and 2. The equivalent period of the system with a shorter partial period increases with increasing coupling, the most in comparison with broad-band seismographs with a constant sensitivity for displacement, velocity and acceleration. This is convenient for long-period seismographs, if the seismometer has a shorter partial period than the galvanometer. An extension of its effective period can be achieved without deteriorating the mechanical stability of the seismometer, however, the effective period of the galvanometer decreases simultaneously.

    Notes: Zusammenfassung Es wurde die Temperatur- und Frequenzabhängigkeit der elektrischen Leitfähigkeit der Eruptionsgesteine verfolgt. Mit Ausnahme der Serpentinit-Proben richtet sich die elektrische Leitfähigkeit im ganzen Temperaturintervall nach dem Exponentialgesetz der Abhängigkeit von der Temperatur. Im Frequenzintervall 102–105 Hz kommt es zu einer starken Dispersion der elektrischen Leitfähigkeit, die mit dem Wachstum der Temperatur sinkt und bei hohen Temperaturen von ca.1000–1050°C praktisch schwindet. Die dielektrische Konstante als Funktion des Frequenzlogarithmus sinkt scharf. Bei tiefen Temperaturen (bis300–400°C) wurde ein Gebiet sehr schwacher Dipol-Polarisation beobachtet.

    Notes: Summary The scale-value switch (Fig. 1) makes it possible to calibrate even the older Askania tidal equipment with a galvanometer at a reduced scale-value. If resistors R 2 and R 3 are selected as shown in Eqs(4) and(5), the ratio of reduction of the scale value1/n does not depend on the internal resistance of the photo-cell in the gravimeter. The resistance of the recording galvanometer R 4 must be determined with an accuracy of±1% in order to obtained an accuracy of±0.5%. Together with the reduction in scale value also the damping is considerably decreased, which enables the time, required for calibration, to be cut down considerably.

    Notes: Zusammenfassung Die Fehler in der Bestimmung der N(M)-Funktion werden diskutiert. Fragliche Ergebnisse können schon durch Vernachlässigung manchmal vorkommender nichtlinearer Verteilung der Punkte verursacht werden. Es wird gezeigt, dass auch bei linearer(log N, M) Verteilung verschiedene theoretische Voraussetzungen einzelner Berechnungsmethoden zu nicht vernachlässigbaren Unterschieden in den Ergebnissen führen können.

    Notes: Summary Virtual geomagnetic poles, corresponding to the directions of primary remanent magnetization of the neovolcanic occurrences studied in the Lower Jeseník, form a close group which is positionally considerably removed from the present geographic pole. By comparison with some published data on the extent of the secular variation of the geomagnetic field, a conclusion was drawn that the assumption of a practically simultaneous generation of the considered volcanites (over a period of about one third of the longest secular variation cycle) is at least twice as probable as the assumption of an expressive difference in their age.

    Notes: Summary A relation between Stokes' constants (harmonic coefficients) J n (k) , S n (k) has been derived in the development for the external geopotential and the coefficients in the development for the single-layer density distributed over the surface of the external ellipsoid, the external equipotential surface, as well as the smoothed physical surface of the actual Earth. Terms of the 2nd order, (J 2 (0) ) 2 , were taken into account, terms of the 3rd and lower orders were neglected.

    Notes: Résumé La densité moyenne de la Terre et la densité moyenne de la couche superficielle, jusqu'à1450 m, furent déterminées `a partir des observations du gradient vertical de la pesanteur, dans la mine „Anna“ à Příbram. Les calculs furent effectués selon les formules(6) et(7), déduites sous la supposition que la Terre soit un ellipsoïde de révolution. Les résultats furent comparés aux valeurs déduites pour l'ellipsoïde astronomique et aux valeurs des densités obtenues des prises de roches dans la mine et on a constaté un bon accord.

    Notes: Summary As regards the concept of complete weight p with which an observed quantity (e.g., the direction of theA–G net) should enter the net adjustment, according to Eq.(1), apart from the fundamental weight p 0 ), determined by the number of repetitions, it should also contain the time parameter pt according to Eq.(11), where c〉1 is a constant, and t is the number of days of observation, and also the refraction factor pr according to Eqs(17, 18), where q is the structural weight of the direction. The condition for being able to determine pr with the directions is observation by means of the three-directional vertex method[2], because it is not possible to localize lateral refraction by angular methods. The theory of complete weight is in favour of observations with a high fundamental weight p 0 which automatically yield higher values of t, and also of pt. The introduction of the complete weight into the experimental directional net in Fig. 2 caused the mean value of the uneliminated refraction error to decrease from 0.24″ to 0.12″, the mean square error of the adjusted direction being 0.17″. The value of the constant c was investigated and the method of determining the parameter pr was derived also for lengths measured electro-optically. Mention is made of the effect of complete weights on the length adjustment of a net in[6].

    Notes: Summary Following the recommendation of the European Seismological Commission (Copenhagen 1966) to carry out comparative measurements on simple seismic models with a prescribed velocity-depth distribution (test models), an attempt was made to compare results obtained with different model techniques. In the present paper, model investigations with the first two proposed test models carried out by 2- and 3-dimensional model techniques are described. Seismogrammes, travel-time curves and amplitude-distance curves of the models investigated are given. A quantitative comparison of the results shows a satisfactory agreement.

    Notes: Summary The paper deals with the magnetic properties of the natural minerals haematite, ilmenite and pyrrhotite. The natural remanent magnetization Jn, the volume susceptibility ℵ, the specific magnetization of saturation σso, the Curie temperature Θ, the A.C. demagnetization of natural remanent magnetization, the thermal demagnetization Jn, the temperature dependence of the specific magnetization of saturation, and several other parameters were determined for the individual sets of minerals. Since natural minerals can and do contain various heterogeneous and isomorphic admixtures, their magnetic properties may change depending on the content and type of these admixtures. Therefore, all the investigations of the magnetic properties described in this paper were carried out with extensive sets of minerals, representing various Czechoslovak and world localities. A number of interesting results were obtained from the executed experiments, e.g., the different stability of the natural remanent magnetization of haematite with respect to A.C. demagnetization, the presence and type of heterogeneous inclusions in ilmenite, the phase changes connected with the γ-transition in natural pyrrhotites, etc. The types of distributions of the investigated values of the magnetic properties were also determined.

    Notes: Summary In 1967, a series of observations were carried out at Lomnický Štít of the intensity of light of the clear sky. Using the de Bary method[1], the observations were used to determine the function of simple dispersion on turbind particles in the atmosphere and compared with theoretical functions, which hold for Jung's power distribution of the particles according to size[7] and for the logarithmic Gauss distribution of the particles[8].

    Notes: Summary Stokes' constants and , the selenocentric constant , and the angular velocity of the rotation of the Moon define the shape of the external equiselenopotential surfaces, generalized in dependence on the degree N of the harmonics preserved. The scale factor for lengths was computed on the basis of absolute gravity measurement made by the first lunarlanding mission Apollo11 at the landing site[1] under the assumption of a sufficient accuracy of the Stokes' constants used[2, 15]. Anyway, the numerical solution here is only to be considered as an example of the application of the outlined theoretical method, inclusive of the parameters of the lunar reference system, which will be made considerably more accurate when gravity measurements at more points of the lunar surface are available.

    Notes: Summary The evolution of the opinions as to the problem of the triaxiality of the Earth in the period prior to satellite geodesy can be seen, e.g., in[1–18]. Recently the opinion has been voiced that triaxiality is a result of the mathematical treatment of data rather than reality[19–21], especially since this is a comparatively small parameter. This opinion is not in contradiction with the results of satellite observations[22–28], but the non-zero values of the harmonic coefficients of the second degree and second order are a reality, they yield a value of the equatorial flattening of about1/90 000, and the representation of the equatorial section by an ellipse is justified even if the harmonics n=3, k=1 and n=3, k=3 have amplitudes only about half as small, and some other parameters might occur with just as much justification besides triaxiality.

    Notes: Summary In processing observed data one frequently encounters the problem of substituting a set of observed values of two variables by a continuous functions. This function is selected in the form of a polynomial with powers of the variable x. A test characteristic is then constructed, F, which has a Fisher probability distribution. The test characteristic has a simple form when orthogonal polynomials are used. By succesive application of the test of the hypothesis that the function is expressed by a polynomial of a given degree the degree and the form of the polynomial is determined.

    Notes: Summary A method has been derived for computing the gravity effect of a segment of an infinite homogeneous elliptical cylinder. The initial data was represented by formulae expressing the components of the field of gravity of a homogeneous two-dimensional body by means of line integrals. The method is based on the integration of theln R function over the boundary of the cross-section of the attracting body, R being the distance from a fixed point in which the gravity effect is determined. The problem was solved in confocal co-ordinates.

    Notes: Summary The development of a function (scalar, or matrix and vector) is indicative of the position of a point in orthogonal curvilinear co-ordinates in a restricted space, and its application to the transformation of orthogonal spatial co-ordinates and to the development of the external potential as well as the corresponding gravity, by means of natural geometry. The principal ideas are discussed of deriving the spatial transformation by continuous representation transforming the given external gravity field of the Earth into the space of the image, so that parallel planes correspond to equipotential surfaces and straight lines perpendicular to the planes correspond to the verticals. The distances of the planes are such that they are proportional to the potential differences in the original space. Also the method of determining the image of the curve and some of the other of its geometrical invariants has been indicated.

    Notes: Summary The core waves recorded at four seismograph stations in Central Europe were investigated with the aim to find the most suitable set of travel-time curves and a fitting model of the core structure. Another travel-time curve was constructed by means of time differences between the core phases. The differences in the features of the travel-time curves were studied using records of shallow, intermediate and deep shocks from the same focal region (Tonga).

    Notes: Summary A statistical treatment is presented of the observed values of natural remanent magnetization and of magnetic susceptibility of natural minerals: magnetite, chromite, ilmenite pyrrhotite, haematite, cassiterite and garnets. It was found that for most minerals the distribution of the natural remanent magnetization as well as the magnetic susceptibility is logarithmically normal at a significance level of p=0.05. The typical values of Jn and x, the limits of the intervals of reliability of these typical values for p=0.05, and the standard deviations of the distribution were determined for the individual minerals. The end values of the sets were tested by two independent tests of extreme deviations at a level of significance of p=0.05. Following statistical deliberations it was proved that the lognormal distribution of the Jn and x values depended on the number of factors affecting these values, independently of the type of distribution of these so-called “disturbing” factors. By generalizing for rocks it was shown that the lognormal and normal types of distribution of Jn and x values are extreme cases as regards the observable types with rocks.

    Notes: Summary Properties of the thermoremanent magnetization of various archaeological materials (baked-clay objects, samples from old trees, bones and stones) were investigated with the purpose to assess the possibility of their use for the determination of the earth's magnetic field in the historical past and to apply the data for solving some practical problems. It turns out that most of those materials yield magnetic values that can be used for making the radiocarbon dating method more accurate, for determining the degree of burning and for direct archaeomagnetic dating. The new conclusions also contribute to the knowledge of changes in the earth's magnetic field in the past.

    Notes: Summary The anisotropy of the Cs137 gamma-ray absorption coefficient has been investigated in layered models and several rock samples. It was found that in contrast to other petrophysical parameters the gamma-ray absorption coefficient $$\mu _{Cs^{137} } $$ is characterized by a relatively small coefficient of anisotropy (3–5%). Therefore, the possible effect of the anisotropy can be neglected in the measurements of μ for rocks as it is usually below current observational errors.

    Notes: Zusammenfassung Die grundsätzliche Schwierigkeit der Konstruktion statistischer Mechanik der turbulenten Strömung besteht darin, dass es keinen allegemeinen Nachweis eines Theorems über die Eindeutigkeit der Navier-Stokes'schen Gleichung gibt. Unsere Bestrebungen wenden sich deshalb zum Studium solcher Bewegungen, die durch lineare Gleichungen ausgedrückt werden. Unter solche gehört auch die Bewegung der im Feld der turbulenten Strömung diffundierenden Teilchen, die am Modell einer zufälligen Teilchenbewegung im Phasenraum (x, p) studiert wird. Dabei wird vorausgesetzt, dass diese Bewegung aus einem gewissen Anfangszustand realisiert wird, dem ein bestimmtes, durch eine Störung des Systems bei dessen Beobachtung bedingtes anfängliches „Unbestimmtheits-Gebiet“ entspricht. Daraus ergibt sich die Ergodizität (genauer gesagt die Quasi-Ergodizität) des Systems, die als Folge einer noch allgemeineren Eigenschaft des Systems mit Verschmierung (Durchmischung) des Anfangszustandes gilt. Vom Gesichtspunkt der Ergodizität und Irreversibilität des Prozesses wird die Struktur der statistischen Mechanik irreversibeler Prozesse studiert und ihre Beziehung zur Struktur der turbulenten Diffusion diskreter Teilchen gesucht.

    Notes: Summary An experiment was run at the Ondřejov Observatory to test the fundamental equipment for constructing a satellite laser radar system, to check the assumptions, calculations, and the methods of measurement. Using a modified SBG chamber, a laser of Czechoslovak production was employed to measure the distance to the GEOS B satellite. Good results and a sufficient power reserve of the experiment have thus become the fundamental stepping stone of constructing a satellite laser radar system. The short contribution which follows gives a brief description of the experiment and some of the results obtained.

    Notes: Summary For precise geodetic computations over larger distances the reference surface of an ellipsoid of rotation should be used. However it is often replaced by a sphere of an adequate radius. The formulae are derived from figures which usually represent the conditions in a cross-section of the ellipsoid and the reference sphere through the normal plane. Equation (9) is given for the differences Δs of the length of the ellipse arc of the normal section and the corresponding arc of the circle with radius R. Also Eq. (19) is given for the distance d between the ellipse of the normal section and the circle (at the end point). Both equations are applied for various radii of the reference sphere. Table 1 shows the values Δs, Tab. 2 and Fig. 2 give the d-values for chosen lengths. It was found that especially the distance between the ellipsoid and the sphere need not always be negligible.

    Notes: Summary In order to evaluate the accuracy of measurements repeated by a set of gravimeters the semi-systematic errors σ 2 and σ 3 were introduced besides the random error σ 1 in[1]. It is shown that Eqs.(10) and(11), given in[1], should not be used to determine these errors, but Eqs.(8) and(9).

    Notes: Summary A new procedure of the relative orientation of pencils of light reconstructed from aerial photographs having 60% end and side overlaps is suggested. The basic unit for the procedure is a quadruplet of photographs forming a square. The geometrical characteristics of a block of photographs with 60% overlaps are exploited fully, and, the present author believes, that way an optimum relative orientation of all photographs within the block can be achieved.

    Notes: Summary Interpolation and projective methods are compared referring to corrections and or transformations of photogrammetric fields of points. Too many fixed points are needed for a reliable interpolation and, therefore, the interpolation methods are not economical. It is suggested to correct the image coordinates by means of the affine transformation, and the author states that four fiducial marks are sufficient for the transformation if they are placed in the image corners. The relations between the photogrammetric model on one side and the projection of the earth surface and the elevations above sea level on the other side are discussed.

    Notes: Résumé On donne les résultats de l'analyse de la dérive des pendules horizontaux de la station Příbram-Březové Hory au cours des années 1927–1938. Différemment aux résultats publiés déjà antérieurement[2], on a tout d'abord séparé par la méthode des moindres carrés la dérive linéaire et le terme à période de durée d'un an exactement et ce n'est que le reste qu'on a analysé par la méthode de l'analyse spectrale spéciale[4, 6]. On a trouvé dans les deux éléments une période de 222, respectivement 223 jours, non considérée jusqu'alors et ne pouvant pas être interprétée jusqu'à présent du point de vue physique. Les autres résultats sont en bon accord avec ceux reçus à l'origine. On peut conclure de la comparaison des phases des composantes annuelles des pendules horizontaux et du mouvement du pôle[5] que les deux événements sont du même origine.
