    Notizen: Tunisia A has long been regarded as a model of political development and stability in the Third World. There is no doubt that the charismatic Habib Bourguiba, the aging (71) yet indefatigable leader of an effective nation-wide party apparatus, has helped ensure Tunisia's development from the period of the pre-independence struggle until today. It is not unnatural, therefore, given the critical role of Bourguiba in the operation of the political system, to question the degree of institutionalisation, stability, modernity, and democracy that Tunisia could retain after the passing of its dynamic leader.

    Notizen: Lenin set the tone for most successful revolutions in the twentieth century when he altered traditional Marxism to suit the conditions of Russia. Mao Tse-tung followed Lenin's example when he too adjusted Marxism (and Leninism) to a Chinese environment. It seems to follow, therefore, that attempts at revolution everywhere should not be mere imitations of previously successful upheavals but should, instead, be tailored to fit specific circumstances. Thus, African revolutions should be made on the basis of African conditions. But such conditions are not, in general, always easy to discern, nor are separate analyses of those conditions certain to be similar. This is especially true of the theories of revolution of two of the most important and influential figures in recent African history: Frantz Fanon (1925–61) and Amilcar Cabral (1925–73).

    Notizen: The idea that Russia was the first underdeveloped country has begun to gain currency among political scientists. It implies that social processes in Russia may be profitably compared with more recent developments in the Third World. In this article I would like to test this hypothesis with respect to an important ideological controversy which took place in Russia during the nineteenth century by examining it alongside discussions among French-speaking West Africans in the period after World War II. More particularly, I would like to compare what might be called the neo-traditional themes and anti-western patriotism of the Slavophiles with the intellectual position taken by the early spokesmen of négritude.

    Notizen: This article was written before information on the great Ethiopian famine of 1973 had reached the outside world. Since I was not then aware of the catastrophe, the facts given here should not be regarded as a reconstruction of the causes of the famine. On the contrary, the deterioration in the conditions of the indigenous inhabitants had been known for some years – in fact, since the beginning of the capitalist offensive in the north-eastern lowlands of Ethiopia, namely the Awash Valley. I had already predicted the famine in late 1971 in two reports,1 and in discussions with officials of the Ethiopian Government.

    Notizen: After many years of poverty and neglect, Mali is today faced with a unique opportunity to develop its rural economy. The rapid expansion of demand for beef in some of the coastal regions of West Africa has recently caught up with the available supply from the interior, and cattle prices have increased dramatically. This price rise has been accentuated by the effects of recent drought which seriously depleted the herds. Consequently, there is enormous incentive for interior regions to find new ways of increasing production which, at the same time, take pressure off their overburdened range-lands. Mali is fortunate in having a resource endowment which has considerable potential in this respect.

    Notizen: The English-speaking independent countries of Central and Southern Africa, with widely different economies and natural resources, face at this stage in their development very similar manpower and educational problems. Shortages of skilled technical workers are still acute in Botswana, Lesotho, Swaziland, Zambia, and Malawi; and shortages of educated people, particularly those with professional or degree-level qualifications, are obvious. Most of the countries in this region, therefore, are still at a stage where the output from schools and universities has not yet been sufficient to localise many skilled posts, particularly those in the private sector. So although unemployment is beginning to appear at the junior secondary levels, the crucial questions as seen both by ministries of education and by planning units still tend to revolve around the central dilemma of ‘How fast ought we to expand?’ In this sense the priorities are different from many countries further north in Africa where surpluses of secondary and higher educated workers have been apparent for some time.

    Notizen: The creation of an international secretariat is ‘the innovation that transforms a series of conferences into an organization’1 The signing of the Charter of the Organisation of African Unity by representatives of 30 independent states in the early hours of 26 May 1963 at Addis Ababa was certainly intended to transform a multiple series of international conferences—including rival meetings of the ‘Monrovia’ and ‘Casablanca’ states in particular—into a permanent regional organisation whose membership embraced all independent African states. To this end the O.A.U. Charter provided for a General Secretariat, to be directed by an Administrative Secretary-General and one or more Assistant Secretaries-General.

    Notizen: This article represents an attempt to bring together and survey the diverse techniques devised by individual scholars and institutions for the purpose of measuring comparative economic development. Any merits it therefore possesses must rest in its clarifications rather than in its inspirations. However, so many techniques exist, founded upon so many theoretical bases, that a concise overview would appear to be justified.

    Notizen: The culture of a country, or a society within it, provides the context for education. The planning of education should therefore start with a consideration of the cultural background, and this is especially true of those countries in Africa which are predominantly Islamic. However, when an attempt is made to follow this line of approach, the complexity of the situation soon becomes apparent; and it is necessary to bear in mind several themes that constantly arise.

    Notizen: In March 1961 the Democratic Party won the national elections in Uganda largely because it captured o of the 21 seats within the Kingdom of Buganda. The Buganda Government had ordered a boycott of the elections, because neither the British administration nor the African political parties would guarantee Buganda's future position within Uganda, and all but three per cent of the electorate stayed away from the polls. The Democratic Party took office despised within Buganda because it had defied the Kabaka, and feared by his Protestant advisers because of its predominantly Catholic support.

    Notizen: The introduction of the one-party system in Tanzania in 1965 was in part explained as a means of rescuing the National Assembly or Bunge from decline and decay. This institution had become a rubber stamp, according to the Presidential Commission, making few meaningful contributions to the system of government: debates had become ‘lifeless and superficial’, and legislation was passed rapidly and uncritically, ‘without challenge to basic principles or careful examination of detailed provisions’. The President had appropriately raised the question of whether the National Assembly should be formally removed from the structure of the state, or amalgamated with that of the ruling party.

    Notizen: Much recent analysis of South Africa's outward-looking policy towards independent Africa has asserted that the implications of this are primarily economic in character: ‘South Africa is thrusting out into Africa for a number of reasons. She needs markets for her manufactured goods. She wants to export capital.’1 Indeed, many observers carry the argument further, and suggest that she is seeking an economic and political role in Africa analogous to that of the United States in Latin America. In the words of Sean Gervasi:

    Notizen: In the past decade Africa has experienced a dramatic decrease in the number of national democratic institutions. Parliaments have not met, parties have declined or been outlawed, and elections have not been held in many states. The situation appears to be similar at the local level. Commenting on this state of affairs, Fred G. Burke observed in 1969: ‘One wonders whether there is to be any future for democratic local government in Africa. One might also wonder whether there should be any future.’2

    Notizen: An incidental aside in one of my books has become the focal point of a small controversy. Experiment with Freedom, India and Pakistan 1947 was a brief work which attempted to give a more precise and particular account of the events which led up to the transfer of power. Most attention has been paid to my interpretation of the celebrated episode at Simla in May 1947 when Nehru reacted violently to Mountbatten's plans for transferring power. I suggested that the crisis was not an external confrontation between British and Indian views over whether India should remain united, or be divided, or split into fractions, but was essentially an internal crisis in the mind of Jawaharlal Nehru. To try to explain why Nehru was so upset by a plan which he had, in all essentials, previously (however reluctantly) accepted, I made a comparison with his later reaction to Chinese activities on the Indian border. Nobody adopted the slogan Hindi-Chini-Bhai-Bhai (‘Indians and Chinese are Brothers’) more ardently than Nehru and so the revelation that they were enemies came as a profound personal shock. Speaking on the morrow of the Chinese invasion, Nehru said that he now realized that they had been ‘out of touch with reality’, in an ‘artificial atmosphere of our own creation’. The Times printed this observation under the sardonic heading ‘The Dreamers’ (26 October 1962). I suggested that at Simla Nehru exhibited ‘much the same apparent amnesia’.

    Notizen: In July 1928, upon the termination of the Northern Expedition, Chiang Kai-shek presented a sacrificial message to the departed leader, Sun Yat-sen, whose body reposed in the Pi-yün Temple outside the city of Peking. Sun had committed his life, Chiang declared, to the attainment of eight tasks in the rebuilding of a new China: (1) the explication of the Kuomintang's principles and the expunging of ‘unorthodox views’, (2) the constructing of a unified party through the curbing of individual freedom and the acceptance of party discipline, (3) the transfer of the national capital to Nanking to symbolize a new beginning for the nation, (4) a purposeful change in the ‘heart’ of the citizenry, (5) the psychological, economic, political and social reconstruction of the nation, (6) the disbanding of troops, (7) the termination of civil strife and a total commitment to national defence, and (8) the speedy introduction of local autonomy. These personal commitments—and public admonitions, as they were also meant to be—covered a wide range of national concerns, dealing as they did with ideology and organization, power and legitimacy, political socialization and national integration. It is noteworthy, however, that Chiang at the moment of personal triumph turned his attention above all to the ideological function of the ruling élite in the transitional Chinese society.

    Notizen: This paper explores the relationship between stress patterns of disyllabic constructions in the Peking Dialect of Modern Chinese and their grammatical structure. It suggests that the existing diverse stress patterns represent different stages of stress shift which is the mechanism employed to signal a formative grammatical process leading from loose syntactical to close morphological constructions. It finally proposes that, apart from the well-known effects of stress shift such as the loss of the tone and reduction in the segmental structure of unstressed syllables, the process ultimately results in the fusion of syllables and the appearance of relatively more complex syllabic shapes.

    Notizen: The Khilafat movement, which took place among Indian Muslims immediately following the First World War, was so called because it was a political agitation designed to pressure the British government to preserve the defeated Ottoman Empire and its ruler, the Caliph of Islam. The Khilafat movement was also, more fundamentally, a campaign to unite Indian Muslims politically by means of religious and cultural symbols meaningful to all strata of the community. The movement gained added significance because it took place simultaneously, and cooperated fully, with Gandhi's first non-violent non-cooperation movement against British rule. Muslim and Hindu were thus engaged in parallel political activity: the broadening of national political participation from the élite to the mass through new techniques of organization and communication.

    Notizen: Both in terms of area and population, the fifteen changwads of the North-east constitute the largest of the four basic regions in the Kingdom of Thailand. Recent census data indicate that 37.9 per cent of the 3.2 million Thai farm households live in this region cultivating a similar proportion of the country's 69.7 million rai (I rai = 0.395 acre) of land in agricultural holdings. However, the region seems to have more than its fair share of the problems which stand in the way of the Government's efforts to accelerate the country's economic development. At present, the solution to the ‘North-east Problem’ remains as elusive as it was a decade ago. In spite of the impressive amount of public expenditure already poured into the region for improving the infra-structure and providing a wide range of rural facilities, together with an ever-increasing amount of services rendered by national and international agencies for planning and implementing the processes of growth, the per caput income of the North-easterner still lags as far behind that of his fellow countryman residing elsewhere in the kingdom as it did in the recent past. This article attempts to analyse the interaction of the physical conditions and socio-economic problems which are bound up in the existing land-use system of the North-east.

    Notizen: The Position of the tribal minorities in the Philippines is fundamentally different from that of comparable populations in other parts of Asia. The manner in which they have been enabled to run their own affairs and retain many features of their traditional culture while simultaneously acquiring Western education and familiarity with certain modern technological achievements is indicative of an approach to minority problems which distinguishes the Philippines from most other Asian countries. Whereas in the former colonial territories of Britain, France and the Netherlands a centrally controlled service of professional administrators endeavoured to impose on all populations, advanced as well as backward, a minimum respect for law and order as seen by the colonial power, in the Philippines neither the Spanish rulers nor the American authorities set up a type of district administration such as existed, for instance, in British India. When in 1898 the Americans replaced the Spanish régime, they did not give high priority to establishing throughout the islands an administration capable of dealing effectively with problems of law and order. In the lowlands they could build on a political system set up by the Spanish, but in the mountains of Northern Luzon, the area with which I am here concerned, they found not even the skeleton of a colonial administration. The entire hill-region was inhabited by warring tribes, torn by feuds and passionately addicted to the practice of head-hunting. Faced with a similar situation in such areas as the Naga Hills on the Assam—Burma border, the British had set about pacifying the tribes, stage by stage, and area by area, establishing outposts of military police and creating administrative units in charge of high-powered and specially selected members of the Indian Civil Service. Village elders were made responsible to these district officers, who administered summary justice in their capacity of magistrates, and this paternalistic system worked well as long as British rule lasted, but was hardly intended to prepare the ground for a system of representative democracy.

    Notizen: In the years 1856–60, Great Britain, France and China were involved in a war, which has been referred to by different names, depending, naturally enough, on the nationality of the historian. Scholars in China, almost without exception, call it the Second Opium War. Historians in England, however, usually prefer to call it the Second Anglo-Chinese War or even the Second China-foreign War. It has been given yet another name, the Arrow War. None of these names is, strictly speaking, entirely appropriate. To begin with, the war was not fought over the question of opium, although in many ways it was a continuation of the Opium War of less than two decades before. In the last analysis, it was a consequence of an ever-expanding British economy. Secondly, although it is true that Great Britain and China were the chiefcontenders, the title Anglo-Chinese War ignores the part played by France in the campaign. Then the name Second China-foreign War, apart from betraying the English desire to forget that part of their past, is misleading because it focuses attention on China herself rather than on British encroachment on that country. Finally, the Arrow incident was, like the burning of opium by Commissioner Lin, an immediate cause of the quarrel; but once London had decided to resort to arms, little further reference was made to it in British diplomatic documents. The name Arrow War is particularly irrelevant for the period after the scene of confrontation had changed from Canton to Tientsin and then Peking. On balance, however, the names Second Anglo-Chinese War and Arrow War seem preferable because they do not carry overtones of nationalist prejudice. The latter title has the additional merit of illustrating how, in the age of European expansion, a small diplomatic incident could be magnified to justify the use of force to press home demands unrelated to it. It reflects the fact that the receiving end—in this case China, and in particular her Imperial Commissioner for Foreign Affairs, Yeh Ming-ch'en—tried throughout to argue the case over the specific casus belli, whereas for the British the whole affair was merely a pretext for wider demands to be made on China. Thus it seems more appropriate to call the conflict the Arrow War; and in order to examine its origins, the first step will be to analyse the documentary evidence related to the Arrow incident. Some papers in the Chinese language have only recently been made available to scholars in the Public Record Office. London, and these provide additional information for a re-investigation of the origins of the war.

    Notizen: George Sansom once called the history of education in late nine-teenth-century Japan ‘a useful example of a reaction against foreign influence and a return to tradition in the midst of a strenuous process of “modernization”.’ Sansom and others have depicted Japanese education during the first three decades of the Meiji period (1868–1912) as follows: during the 1870s Japanese education was completely dominated by the Western philosophies and principles which were flooding a country newly opened to foreign intercourse after two and one-half centuries of isolation. This extreme Westernization led to a ‘conservative reaction’ in government and education circles during the 1880s. This, in turn, culminated in the Imperial Rescript on Education of 1890 and the emphasis on ‘traditional’ moral education which was the hallmark of schooling in the 1890S. This shift in educational policy on the part of the Meiji government has been seen as ‘part of the general swing during the 1880s away from unnecessarily close imitation of the West and back towards more traditional values.’

    Notizen: A technique is described for the determination of crystallographic polarity which is generally applicable to large polar crystals containing an element heavier than K. It is an extension and simplification of Cole & Stemple's method in which the intensities diffracted by (00 l) and (00\overline l) planes are compared at wavelengths close to an absorption edge of a constituent element. A definitive polarity determination may now be made without previously measuring or assuming values of Δf′ and Δf′′ at the edge.

    Notizen: A method is suggested, using diffraction line displacements, to facilitate simultaneous determination of one-dimensional strain in a particular direction in the surface of a polycrystalline material and of the lattice parameter corresponding to the unstressed state. A single exposure at perpendicular incidence of the primary X-ray beam enables both values to be obtained. Full advantage is taken of the ratios of diffraction ring diameters.

    Notizen: A computer program has been written for the evaluation of the size of coherently diffracting domains, microstrains, and stacking fault probabilities for f.c.c. and h.c.p. single crystals. After correcting for instrumental effects, the Warren–Averbach analysis is applied to reflections which are not affected by stacking faults. The fault-broadened peaks are then analyzed and the results plotted.

    Notizen: The methods of Lake [Acta Cryst. (1967) 23, 191] and Schmidt [Acta Cryst. (1965) 19, 938] for calculating slit-length collimation corrections in small angle X-ray scattering have been compared in a number of tests. The tests showed that under most conditions neither method introduces errors larger than the expected uncertainty in present-day scattering data and that slit-length corrections are relatively insensitive to small changes or errors in the weighting function. Neither method is extremely sensitive to random errors in the measured intensity but the effect of these errors is somewhat smaller with Schmidt's method than with Lake's. Three cases were found in which one of the correction methods should be avoided or used with caution: with Schmidt's method errors are produced in the outer part of the scattering curve if the angular increment is too large – a criterion has been developed for determining acceptable increments; if Lake's method is used in an angular region in which a scattering curve has subsidiary maxima or minima, more iterations may be necessary than are required for monotonically decreasing scattering curves; the usual form of Lake's method, which was developed to converge rapidly with curves which have a zero-angle maximum, was sometimes found to give appreciable errors for curves with a pronounced minimum at zero scattering angle. When the latter type of curve is corrected by this method, precautions should be taken to ensure that the collimation correction is not introducing errors.

A26, 97] is described in which the correction to the unitary orientation matrix, valid to second order in the small rotational adjustment, is applied after constraints due to crystal symmetry (which is presumably lost owing to measurement errors) have been applied to the lattice constants, and in such a way as to preserve (to second order) the unitary character of that matrix.

    Notizen: Three methods are described of eliminating the influence of the satellite group in the variance method of X-ray line profile analysis. The first is to interpolate the line profile under the satellite group: however, the satellite group must be reasonably well distinguished from the α1 tail and from the background. The second method is to correct the experimental variance-range curve by a graphical construction: this assumes that the satellite lines and the broadening function are Cauchy in form. The third method is to compute the necessary corrections to the slope and intercept of the linear variance-range function by using model spectral distributions with and without the satellite group. The first two methods are applied to profiles from powders of iron and iron alloys studied with iron radiation, the third method uses an analytical model of the spectral distribution of the iron Kα multiplet. The corrections given by these methods to be made to the slope and the intercept of the variance-range function are nearly constant for all but the smallest amounts of particle-size broadening. It is also shown that particle sizes determined either from slope or intercept of the variance will be underestimated if correction is not made for the satellite group.

    Notizen: Samples of the ferrimagnetic material Ba3Co2Fe24O41, pre-aligned in a magnetic field and sintered at various temperatures, have been examined for preferred orientation. Schulz's reflection technique and the standardizing method of Holland were used to determine quantitative pole figures of several lattice planes. The texture bears a close resemblance to a `fan texture' in which the crystallites have their basal planes parallel to a preferred direction. The sharpness of the texture increases with increasing sintering temperature. At 1320°C an exaggerated grain growth takes place. Inhomogeneity of the magnetic field throughout the sample results in local differences in orientation.

    Notizen: A procedure involving the use of Fourier coefficients is suggested for the separation of the el component from an experimental diffraction profile. In contrast to the well known Rachinger method, the procedure described here does not require experimental data at any predetermined intervals. Furthermore, the separation error, if any, is evenly distributed. As in the Rachinger method, prior knowledge of the α1−α2 angular separation and the ratio R = Iα2(max)/Iα1(max) is assumed. If, however, R is unknown, then the mathematical analysis can be extended to determine the value of R.

    Notizen: The local atomic arrangements in an Au-40 at.% Pd alloy were investigated by measuring the X-ray diffuse scattering from a single crystal. A computer simulation of the short-range structure was used in the interpretation of the diffuse scattering results. The interpretation indicated a tendency toward the formation of a tetragonal AB long period superlattice which has not previously been observed to occur. The static displacements of the atoms from their average positions were shown to be very small in this alloy.

    Notizen: A method is presented for correction of integrated X-ray intensities for preferred orientation in cubic powders. It is based upon examination of the polar axis density distribution, which describes the orientation of crystallites in the specimen, and upon the use of a cubic harmonic expansion in its representation. The method was tested on four specimens of aluminium, which showed different degrees of preferred orientation. The (111), (200) and (220) lattice plane normal distributions of the specimens were determined by measurement of the integrated intensities for various polar angles. Cylindrical symmetry was effected with a specimen spinner. The corrections to the Bragg reflections were derived from the orientation distribution obtained; they ranged from 0.5 to 12%. The final values were in agreement, to the extent of 1% or less, with those of a specimen in which the orientation distribution was random within the limits of experimental error.

    Notizen: A simple and rapid procedure for orientating electron diffraction patterns required for the simultaneous determination of the Burgers vectors of dislocations in twin related or coincidence site related crystals is described. The determination of the Burgers vectors of dislocations in twin related zinc crystals is used as an example of the procedure. The procedure is applicable to all crystal structures and is based on the detailed analysis of the rotations about the optical axis and goniometer tilt stage axis of an electron microscope required to produce desired diffraction patterns from the two crystals of interest. The analysis also illustrates the way in which the tensor notation may be used in elementary vector algebra applied to lattice geometry.

The analysis of the results, which follows the method described by Borie, is based on the approximation of a solid solution Cl−–Br−. The observed values of the distortion constant for the chloride ion are 2–3 times greater than those calculated on the basis of the conventional values of ionic radii.

    Notizen: A method is described for obtaining X-ray diffraction photographs, equivalent to those obtained under single-crystal rotation conditions, from materials available only in the form of fine microcrystalline powders of acicular or platy habit. The technique involves dispersing the crystalline powder in an appropriate thermoplastic polymer followed by streaming orientation of the particles in an extrusion process. The particles are held in their new positions by solidification of the polymer melt. With acicular powders, and using a polyethylene matrix, the orientation is improved by cold drawing. The oriented composite is immediately ready for X-ray studies.

    Notizen: Cation ordering in magnesium and nickel ferrites was studied by X-ray diffraction measurements carried out at the temperature of equilibration and also on quenched specimens. The order parameters on quenched specimens agreed with results previously reported by others but not with values measured at temperature. Previous results on quenched specimens had been described by a simple mass action relation with constant ordering energy. The new results on equilibrated specimens require a modified Bragg–Williams-type relation in which the ordering energy varies with the degree of order. Both ferrites are inverted when in equilibrium at low temperature. Magnesium ferrite approaches a random distribution at high temperature with a Curie point at about 1070°C. Oxygen positional parameters were 0.243±0.001 for both ferrites at room temperature. The lattice parameter of nickel ferrite quenched from temperatures up to 1255°C was 8.3295±0.0001 Å. For magnesium ferrite the lattice parameter varied from 8.3775±0.0001 Å, when quenched from 784°C. to 8.3848, when quenched from 1271°C.

    Notizen: The speed of the conventional process of X-ray diffraction photography can be greatly improved by the use of a new industrial X-ray film and a fluorescent screen. This process produces a transparent film with about a tenfold decrease in exposure time and at a cost less than that of standard nonscreen film.

    Notizen: The lattice type of the co phase in Ti–30%V alloy was determined with the X-ray precession method. Plane-net patterns of reciprocal lattice levels, normal to [110], [100], and [111] directions of the β phase, indicate that the ω phase has a b.c.c. structure with a lattice parameter three times that of the β phase.

    Notizen: The increasing use of the electron microprobe analyser in research laboratories in recent years renewed the interest in the Kossel line method. Since it is possible to obtain diffraction patterns from selected areas – smaller than 5 microns diameter – this technique has been applied to measure the grain orientation in polycrystalline materials. Comparing the different published methods of interpreting the Kossel patterns, it has been found more convenient to use a digital computer with a peripheral graph plotter to obtain charts.

    Notizen: For accurate absorption-correction calculations, a precise knowledge of the crystal shape is essential. A least-squares determination of the coordinates of the crystal apices according to the analytical expressions derived is obtained by taking a series of silhouette photographs of the crystal directly on an X-ray diffractometer with a pinhole in the incident beam and using soft continuous X-radiation.

    Notizen: A new method for the phase control in an optical diffractometer is described. A photographic negative of the weighted reciprocal net is used as the mask of the diffractometer. The phase of each reciprocal point is represented by the shift of the position in the reciprocal plane. Although this method cannot reproduce the periodic image of a crystal, it is particularly suitable for reconstructing the image of a molecule in a crystal.

    Notizen: Unusual SiC polytypic features have been studied by X-ray diffraction and chemical etching to increase understanding of their growth mechanism. The feasibility of periodic slip as a possible mode of growth of SiC polytypes has been examined. It is proposed that island formation on the helicoidal growth surface is responsible for most of the unusual SiC polytypes not explicable purely in terms of a screw-dislocation mechanism.

    Notizen: All the information relating to the quantitative composition of a mixture is coded and stored in its X-ray diffraction pattern. It has been the goal of X-ray diffraction analysts since the discovery of X-rays to retrieve and decode this information directly from the X-ray diffraction pattern rather than resort to calibration curves or internal standards. This goal appears to be attained by the application of the `matrix-flushing theory' and the now-proposed `adiabatic principle' in applied X-ray diffraction analysis. The matrix-flushing theory offers a simple intensity-concentration equation free from matrix effects which degenerates to `auto-flushing' for binary systems. The adiabatic principle establishes that the intensity–concentration relationship between each and every pair of components in a multi component system is not perturbed by the presence or absence of other components. A key equation is derived which conducts the decoding process. Both the matrix-flushing theory and the adiabatic principle are experimentally verified.

    Notizen: X-ray diffraction topography using transmission geometry has revealed an interesting array of extremely straight and narrow long-line images in sizeable copper single crystals grown under particular growth conditions by the Czochralski technique. These images are analyzed and elucidated by a model of Lomer–Cottrell dislocations. The formation of these sessile dislocations usually aids the growth of large copper crystals of high perfection. The high degree of perfection over the entire volume of the crystals accounts for macroscopic arrangements of Lomer–Cottrell dislocations which have not previously been observed by electron microscopic techniques.

    Notizen: Investigations of many imperfect single crystals of different materials by means of a γ-diffractometer show that the mosaic structure of large single crystals is often very inhomogeneous: the mosaic distribution function has neither a Gaussian nor a Lorentzian shape and the shapes differ remarkably for different volume elements in the sample. Current extinction theories must be considered with reservation because Darwin's intensity transport equations are solved assuming the scattering length for a given angle of incidence to be constant all over the irradiated crystal volume. This is not true for samples with inhomogeneous mosaic structure.

    Notizen: Superlattice formation in thin films of copper–gold alloys has been studied by the use of optical-diffraction analogues. Fraunhofer diffraction patterns of arrangements of holes in opaque screens have been compared with electron-diffraction patterns of the alloy films. It has been found possible to draw some general conclusions about the ways in which the antiphase domains fit together to produce certain characteristics of the electron-diffraction patterns. Some ideas are put forward about the growth of superlattices.

    Notizen: A drum-scanning microdensitometer has been automated with a minicomputer equipped with a magnetic disk memory. Part of the disk is used for temporary data storage, in a manner allowing rapid retrieval. X-ray diffraction photographs from macromolecular crystals can be measured at rates up to about 25 reflections per second, with the flexibility of an `on-line' system. The method can also be used when the computer is time-shared, but with lowered film-processing rates dependent on the number of `simultaneous' (time-sharing) users.

    Notizen: A profile-fitting algorithm has been applied to the determination of X-ray diffraction intensities from precession photographs. It is assumed that each reflection on the film has the same profile or scaled intensity distribution, over a two-dimensional array of points about its center. The integrated intensity of a reflection is that scale factor which gives the best fit between a scaled model profile and the optical density measurements of the reflection. The systematic error in the calculated intensity was evaluated from the discrepancy between the model and observed profiles and was about 2% for strong reflections (about 1.5 OD units). Profile fitting reduced the likely random error in the intensity, produced by errors in optical density measurements, to half the value given by conventional integration. This gain is especially significant for weak reflections which form the bulk of protein data sets. A comparison between film data processed by this method and diffractometer data for the protein lactate dehydrogenase, (34000 Dalton in asymmetric unit), showed that film data agreed with diffractometer data as well as diffractometer data sets agreed among themselves. Film data for glyceraldehyde-3-phosphate dehydrogenase (144000 Dalton in asymmetric unit) had a reliability index of 6% and significant Bijvoet differences were measured for mercury derivatives of the protein. Methods for the correction for non-linear effects in film data are evaluated for model data. It is shown that these corrections give significant improvement only when the data satisfy two conditions: they extend over a wide range of optical densities (at least 20D units) and they are reliable (better than 4% reliability index). Under these conditions an extended version of the Hamilton, Rollett and Sparks scaling algorithm performs better than the other methods considered.

    Notizen: The construction and successful operation of a Laue-case skew-symmetric two-crystal X-ray interferometer is described. The alignment is accomplished with an auxiliary X-ray beam, which is multiply reflected by both interferometer parts. As expected, the skew-symmetric two-crystal interferometer is found to be considerably less affected by vibrations than is the symmetric two-crystal interferometer. [Bonse & te Kaat (1968), Z. Phys. 214, 16–21]. The dependence of the crystal lattice moiré pattern on rotations about the Δρ and Δ&thgr; axes are investigated.

    Notizen: Precession X-ray films were scanned with a rotating-drum microdensitometer. It is necessary to correct for non-linearity between the scanner input and output. Reliability factors for estimating the precision of scanner measurements are compared. The values of the symmetry-averaged reliability factor, Rsym, vary between 3.9 and 12% and depend strongly on the quality of films, while the values of the scanning reproducibility factor, Rrept (3.5–4%), and the film-scaling reliability factor, Rscale (4.5–5.5%), depend more on the quality of scanner software and electronics than on films.

    Notizen: This article is the text of a general lecture given at the Ninth International Congress of Crystallography, September 1972, at Kyoto, Japan. The lecture begins with the famous experiment of Kikuchi and continues with results of work carried out under the leadership of Miyake and the author. The main topics in the former part are: anomalous enhancement and splitting of Bragg peaks, appearance of non-Bragg maxima, dynamical multiple refraction, etc. Dynamical theories including inelastic scattering are introduced, and the formation mechanism of Kikuchi bands and absorption effects are explained. Electron diffraction and electron microscopy, which were originally developed as different fields, have been unified after 1950. The development of high-voltage electron microscopy is emphasized. The reason for the enhancement of dynamical effects at very high voltages is explained in terms of relativistic diffraction theory. As an example of some most remarkable dynamical effects, the vanishing of the second-order reflexion is described. Finally, the findings and developments in moiré patterns and lattice images are reviewed briefly. The lecture is devoted to diffraction phenomena themselves and applications to structural studies are excluded.

    Notizen: X-ray divergent-beam anomalous-transmission patterns of [111] Gd3Ga5O12 crystal wafers cut from Czochralski-grown boules were obtained with Co radiation. The patterns contained {800} Kα transmission conics which just miss having a triple intersection. The intersection region was analyzed to determine the lattice parameter. The values of lattice parameter for wafers cut from several different boules ranged from 12.3807 to 12.383 Å with an estimated precision of ±0.0004 Å. The method is simple and non-destructive and offers sufficient precision to investigate compositional variations and to evaluate the crystals in terms of lattice parameter matching requirements for epitaxic film deposition.

    Notizen: Measurements made by small-angle X-ray scattering on Al–Ag alloys aged at various temperatures have shown that the asymptotic Porod's law was obeyed except for a constant term. This additional term represents a Laue monotonic intensity, due mainly to atomic concentration fluctuations inside G.P. zones. The integrated intensity Q0 of the G.P. zones themselves can then be calculated, and the boundaries of the metastable miscibility gap estimated with more precision than previously. Furthermore, the integrated intensities in the first reciprocal-space shell make it possible to discuss the crystallographic structure of the G.P. zones. After quenching from 550 to −80°C, the measured intensities agree with the theoretical values, which implies that small G.P. zones ε′ are disordered. However, for aging above room temperature, there is no agreement between measured and theoretical values. When the aging temperature is increased from 140 to 190°C, an evolution towards a complex structure of G.P. zones is shown.

    Notizen: Optical-transform methods remain useful aids in determining the structures of polymers, and other disordered materials, from X-ray scattering data. Hitherto a major difficulty has been the preparation of diffracting screens which contain sufficient information to specify adequately the material being studied. The Optronics P-1500 Photowrite system overcomes this difficulty. The equipment is described briefly and two examples of its use in optical transform methods are given.
