    Description: The paleosols of the Last Interglacial are presented in many loess sequences of the European temperate zone by soils with Argic horizon, that are considered to be the pedological response to the bioclimatic conditions of that period. We studied micromorphological, physical/chemical (bulk chemical composition, texture and dithionite-extractable iron) and mineralogical characteristics of two profiles – an Eemian Luvisol in Upper Austria (Oberlaab) and a Mikulino Albeluvisol in Central Russia (Alexandrov Quarry near Kursk) to compare them with recent analogous soils and to make further paleoecological and chronological inferences. Both profiles showed a set of characteristics indicative for weathering of primary minerals, clay transformation illuviation and surface redoximorphic (stagnic) processes. Paleosols demonstrate more advanced development than the Holocene analogues manifested however in different pedogenetic characteristics. The Eemian Luvisol in Upper Austria is characterized by stronger clay illuviation manifested in higher clay content and abundance of illuvial clay pedofeatures in the Bt horizon. Mikulino Albeluvisol in Central Russia is more strongly affected by eluvial and stagnic processes evidenced by deeper and more intensive accumulation of bleached silty material and clay depletion. We suppose that the properties of parent material are responsible for these differences. Russian Albeluvisol is formed on the Dnepr loess poor in weatherable minerals and having limited capacity for buffering acidity and clay formation. The higher development status of the Last Interglacial paleosols compared to the Holocene soils having however same type pedogenesis implies longer soil formation period, that agree with some of the paleobotanical proxies and could include besides MIS 5e part of MIS 5d; the warmer and moister paleoclimate during MIS 5e could also account for more advanced paleosol development Several phases of clay illuviation interrupted by frost structuring and deformation are detected in the Eemian Bt horizon in Upper Austria. It suppose even longer development that could extend to the Early Würmian interstadials (late substages of MIS5).

    Description: After a long decline of gold production in Ghana since 1986 the gold mining sector is recovering and mainly foreign investment led to substantial exploration efforts as well as to the opening up of new mines and/or rehabilitation and expansion of the existing mines after their divestiture (privatization). Foreign junior exploration and mining companies and established international mining houses are currently exploring the country in search of large, therefore commonly low-grade gold deposits which are amenable to highly mechanized open pit mining. Beside such orebodies of the disseminated type or in granites, Ghana is endowed with many occurrences of gold quartz veins and banket reefs, which vary in width from a few centimetres to several metres and have striking length from a few 10 meter to several kilometer. Whilst such larger orebodies with ore reserves of above 1 Mio. tons are a target for industrial mining operations, the smaller "stringer"-occurrences are not of interest, if not only as indicators in prospection for possible adjacent disseminated mineralization. Such restricted orebodies could offer investment and employment opportunities for Ghanaian owned mining groups and companies and should therefore contribute also to economic development of the hinterland. Some of these orebodies as well as the ubiquitous gold bearing alluvials are currently mined by artisanal small scale miners, commonly called "galamsey", which use manual labour only and employ simple handtools in their operations. A visit to such operations will convince any observer that in almost all cases the operations are either inefficient, including the skimming of orebodies, or dangerous, or environmentally unsound or a combination of these. This is due to the long oppression of small scale mining activities first by the Colonial Government from about 1920 ongoing, later by the Ghanaian authorities after Independence. Only in 1986 under the Minerals and Mining Law, PNDC-Law 153 was the small miner legally recognized and a basis laid for his operations. Vast experience in narrow vein mining, which was available among African small scale miners before and around the advent of this century has been lost. To prove this point, mention should be made of the African engineer T.B.F. Sam, who managed and operated singlehandedly the Adja Bippo Mine near Tarkwa before 1900, the only mine of all the mines in operation since 1880 which was profitable and declared dividends (Rosenblum, 1974). Today it can still be assumed that there will be no re-juvenation of skilfull vein mining by African small scale miners as long as it has not been proved to Ghanaian investors that such operations could be viable. The proof can be presented best by a few reference operations applying durable, locally available machinery, simple and sound mining and extraction methods, basic safety standards and bearable working conditions as well as in their effect on the environment controlled operations. Such reference mines could also provide the necessary information in respect of day-to-day running problems, required amounts of investment, minimum working capital, maintenance and repair needs and problems with unskilled labour drawn from the surroundings of such small mines, to mention only a few areas of missing experience.

    Description: A detailed study of a loess-paleosol sequence in Oberlaab, Upper Austria, is presented with emphasis on macro- and micromorphological features, grain size distribution, rock magnetism properties, and weathering degree that allows correlation with other loess-paleosol sequences in neighboring areas, and interpretation of main pedogenic trends. The studied sequence comprises four paleosol complexes, which likely developed during four interglacial stages MIS 11, 9, 7 and 5e, and a modern soil. The oldest paleosol complex (OL5) represents three phases of soil formation, and distinct sedimentary events never reported in the area, with strong reductomorphic properties. The OL4 profile also results from three phases of pedogenesis with increased reductomorphic features in the deepest zone (affected by cryoturbation events). OL3 has abundant features related to gleyic/stagnic processes, but shows signs of clay illuviation. OL2 (Eemian soil) correlates with the MIS 5e. This paleosol shows higher degrees of clay illuviation and weathering, and fewer features related to reductomorphic processes. The modern soil is also polygenetic and constitutes a pedocomplex. Its lowermost part is formed by Würmian glacial deposits, where no well-developed soils are found; only reworked materials and pedosediments. Main pedogenic trends in the sequence are clearly differentiated. All of the paleosols were formed in humid environments, but differing in drainage conditions. The base, with OL5 and OL4 paleosols, was more affected by gleyic processes, while in the upper paleosols, especially OL2, clay illuviation is dominant. We interpret such differences to be caused by the topographic position. The basal paleosols were more affected by fluvioglacial processes due to their position on top of the terrace. The upper paleosols received increased amounts of sediment through fluvial, colluvial and aeolian (loess) input.

    Description: The more than 12 m thick loess-paleosol sequence in Paudorf, Lower Austria, has been known for decades as locus typicus of the “Paudorfer Bodenbildung” (Paudorf paleosol). The upper section of the outcrop contains an up to 1 m thick pedocomplex that developed during MIS 5. The differentiated sequence of loess-like sediment below, including a more than 2 m thick pedocomplex in its basal part, is an exceptional archive of landscape evolution from the Middle Pleistocene. Herein we present detailed paleopedological and sedimentological surveys, as well as first micromorphological observations to address the sequence in its entirety and the processes leading to its genesis. Furthermore, high resolution color and carbonate analyses, as well as detailed texture analyses, have resulted in a substantial database. The studies show that the loess sediments were subject to a polygenetic development under periglacial conditions reflected in eolian silt and fine sand accumulation, admixture of local material during (mostly solifluidal) redeposition and in situ processes. Horizons with signs of pedogenesis, particularly the two pedocomplexes, document longer phases of stability; the stages of development can be correlated to equivalent sequences and seen as paleoclimatic signals where chronological data are available. The upper pedocomplex is a Chernozem of the early last glacial (MIS 5c–[a?]), which developed in a solifluidal redeposited (MIS 5d) interglacial Cambisol (MIS 5e). Cryosols, typical for MIS 6 sequences, are present in the loess sediment below. The lower pedocomplex formed during several warm stages of varying intensities, with interruptions caused by colluvial processes and admixture of eolian sediment during colder stages.

    Description: Since 1980 the Institute of Mining and Geosciences of the Technical University of Berlin carried out an educational project at the University of Science and Technology (UST) in Kumasi and the UST School of Mines in Tarkwa, Ghana, Westafrica. Eichmeyer (1) reported about this project already, in which this author did participate. This project of scientific cooperation in the areas of mining and minerals sciences is not the first contact between Germany and Ghana (earlier called Gold Coast or Guinea). At the end of the 17th Century the Brandenburg-Prussians had undertaken mining activities on the Gold Coast already apart from gold-trade. The historical background of these early mining activities will be presented in the light of the then prevailing political and economical conditions. In this context the early mining attempts of other European powers as well as the indigenous mining activities in those days are described. The development of the modern industrial gold mining sector in Ghana was presented by Gosten and Peters (2) elsewhere.

    Description: This book attempts to outline the history of gold mining and related subjects like marketing, trading and use of gold from the legendary times until today. The work will not limit itself to the borders of present day Ghana but will have to consider also adjacent areas of today's Mali, Burkina Faso, Niger and Nigeria to put especially the earlier historical developments into their proper context. This History will attempt to piece together not only the technical development of gold mining, but the historical, political and socio-economical pressures which caused and were also generated by the development of the gold mining sector within this geographical area. A disadvantage for the historian digging into West African History is the fact that the peoples dwelling in these areas had not developed written records but rather depended on oral tradition of their history. Systematic attempts to preserve this oral history through taping or writing down were undertaken only over the last 100 to 150 years, in sporadic attempts may be a little earlier. The historical events of the last millenium, i.e. from 1000 A.D. to today can be reconstructed for the first half through the written records overcome by the efforts of the muslim scholars, which in a very scientific manner recorded historical, political, economical and social developments in West Africa and in the sub-Sahelian areas. Over the last 500 years the advent of European traders, missionaries and adventurers produced written records of events they encountered during their more or less long ventures at the shores of the West Coast. Of course, a lot of information they gathered and laid down in their records was based on hear-say sources because only very few adventurers penetrated the hinterlands. Nevertheless, we will realise that all these records, as one-sided and biased they might be in many cases, together with oral tradition culled from the traditional rulers and archeological evidence, can form a quite solid basis for the reconstruction of historic events in West Africa in general and the area of today's Ghana in particular. Completely different is the picture for the earlier times, i.e. before 1000 A.D. for the three millenia back to 2000 B.C. We are very certain that negroid ethnics were populating the West African lands but we do not know where they came from, how they called themselves, which political and socio-economic systems they had developed for themselves and whether or when they perished, migrated away or were absorbed by other negroid ethnic groups who themselves migrated from almost uncertain directions into these tropical rainforests. In short, whilst we can speak of the Bono, Gyaman, Guan, Asante for the last millenium, we can only call the previous inhabitants the black "West-African", sometimes differentiated according to distinct cultures named according to the location of their archeological finds, like Ntereso, Nok, Benin etc. These sites prove the existence of highly developed cultural and technical skills expressed in the overcome artefacts found in the excavations. But the curtain in respect of the true nature, descendancy, sociology of these people, who were the originators and perpetuators of these documented cultures, can not be lifted. Here reflection on the flow of historical events from the ancient times to modern times. Guggisberg's citation We will leave it to you, the esteemed reader to form an opinion on the question: Did the development of the gold mining sector benefit the People of Ghana ?

    Description: This publication is the continuation of a previous presentation of the operation and cost analysis of the partly mechanised Tetrem small scale gold mine which discussed in detail the mining, safety and environmental aspects of the venture. At Tetrem, various experiments with different machinery for crushing and grinding the ore in preparation for gravity separation (sluicing) were carried out and the results are presented. The trials led to the construction and application of suitable, locally obtainable equipment for such milling operations. Continuous weighing and sample checks at the different stages of the comminution and gravity separation provided interesting production and recovery data which could be of help for similar operations. Trials for improved recovery of gold from sulphidic ores were carried out and showed the restrictions of gravity separation when confronted with such „fresh ores“. The amalgamation process, recirculation of tailings, special handling of tailings for recovery improvements are described. An overview about the results obtained during six months of operation is presented. Improvements for the locally produced machines and problems with maintenance and repairs of the equipment as well as strategies to solve them are discussed. The experiences obtained in the marketing of the final gold product are critically outlined.

    Description: Die vorliegende Arbeit stellt die paläomagnetische Bearbeitung der Mittel- bis Oberpleistozänen Löss-/Paläoboden-Sequenz im Areal der ehemaligen Ziegelei Würzburger in Aschet bei Wels vor. Fünf intensiv entwickelte Paläoböden, bzw. Pedokomplexe wechseln mit dazwischen geschalteten Lößlehmlagen ab. Im Rahmen einer Aufbaggerung konnte ein Profil mit einer Mächtigkeit von über 12 m erschlossen werden. Für die magnetostratigraphischen Laboruntersuchungen im Paläomagnetiklabor der Montanuniversität Leoben wurden insgesamt 587 orientierte Proben entnommen, so dass eine beinahe lückenlose Beprobung vorliegt. Die Proben wurden mit magnetischen Wechselfeldern sowie thermisch abmagnetisiert. Zur Bestimmung der magnetischen Trägerminerale in den Sedimenten wurden Curiepunkt-Bestimmungen durchgeführt, die eine Hauptträgerphase mit einem Curie-Punkt bei ca. 580°C (Magnetit), sowie untergeordnete Anteile von Hämatit mit 670°C Curie-Punkt ergaben. Die magnetischen Parameter zeigen eine Folge von Bereichen mit intensiver Magnetitbildung in den Paläoböden, die dem relativ wärmeren Klima von Interglazialen zugeordnet werden können. Die Mehrzahl der Proben zeigen charakteristische Remanenzrichtungen im Bereich des normalen pleistozänen Erdmagnetfeldes. In einigen Profilabschnitten traten stark abweichende Remanenzrichtungen auf, die auf Exkursionen des Erdmagnetfeldes hinweisen. Die beobachteten Exkursionen im Profil Wels-Aschet werden aufgrund paläopedologischer-pedostratigraphischer Ergebnisse in das Zeitintervall von 570 ka (Emperor - Big Lost - Calabrian Ridge) bis 110 ka (Blake) gestellt. Die Brunhes/Matuyama-Grenze (776 ka) wurde nicht erreicht.

    Description: Auf den mittelpleistozänen fluvioglazialen Terrassen der Traun-Enns-Platte in der Region um Wels (Oberösterreich) wurden drei Löss-/Paläobodensequenzen untersucht. Jedes dieser Profile ist für mittelpleistozäne Abfolgen im nordöstlichen Alpenvorland charakteristisch. Die Profile umfassen mächtige Pedokomplexe, welche eine Differenzierung und Einstufung von interglazialen Paläoböden erlauben. Die Löss-/Paläobodensequenz von Oberlaab ist auf der fluvioglazialen Terrasse des Mindel-Glazials im klassischen Sinne entwickelt (Jüngere Deckenschotter) und weist vier interglaziale Paläoböden auf. Diese Tatsache macht eine Einstufung der Jüngeren Deckenschotter mindestens in die fünftletzte Kaltzeit wahrscheinlich (MIS 12). Die Deckschichten auf den Günz-Deckenschottern im klassischen Sinn (Ältere Deckenschotter) beinhalten fünf Paläoböden. Beide Lokalitäten weisen eine sehr intensive Pedogenese in ihrem basalen Pedokomplex auf, die wesentlich ausgeprägter ist, als in den überlagernden Paläoböden. Die pedostratigraphischen Ergebnisse lassen eine Einstufung der Älteren Deckenschotter mindestens ins MIS 16 zu.

    Description: Grain size analyses, bulk and clay mineralogical data were used to characterize weathering within the loess-paleosol-sequence of Oberlaab in Upper Austria. Soil horizons can be clearly identified by the calculation of weathering index Kd from granulometric parameters. The mineralogical composition of the bulk samples shows increasing weathering intensity from the top to the bottom. The weakest weathering stage 1 is not present in Oberlaab, because all samples are free of carbonate minerals. Weathering stage 2 can be found in the upper part of the profile, whereas stage 3 is mainly present in the lowermost horizons. The highest weathering stages 4 and 5 are not present in Oberlaab. The clay mineral distribution in the profile is dominated by the disappearance of primary chlorite in the upper part of the profile and the neoformation of vermiculites from illite by pedogenesis in the lower part. Two different types of mixed layer minerals were found in the pedocomplexes. An illite/chlorite mixed layer mineral occurs following the disappearance of chlorite and is present in the Eemian luvisol. The second mixed layer mineral consists of illite/vermiculite and is present in the whole profile. The weathering stages obtained from the clay mineral composition are slightly lower than that of bulk mineralogy, but reach as well stage 3 in the lower part of the profile.

    Description: The economically successful operation of partly mechanized small scale mines in Ghana could fill the gap between large scale, industrial and foreign controlled mining operations and the artisanal (or "galamsey") small scale operations which use only manual labour and simple tools and are mainly confined to alluvial gold deposits and on limited scale to hard rock occurrences. The need to initiate and operate partly mechanized small scale mines stems from the existence of many small orebodies spread all over Ghana which are in their extent and amount of available ore reserves too small to be of interest to medium or large scale mining companies. In this presentation one of these small auriferous orebodies is described and the operation of a small mine is outlined. The employed mining methods during start up and throughout production phases are described. Special attention is given to safety aspects of such operations. A mechanised plant for crushing and grinding the ore in preparation for gravity separation (sluicing) was set up by using locally obtainable or manufactured crushing, seeving and milling equipment. The extraction results over 6 month operation are presented and discussed. The total investment for the small mine and the production costs are presented giving an overview on the economics for such operation. Factors to be observed to safeguard a small mine from causing adverse environmental effects are discussed. Finally, an outlook in respect of multiplication of such operations in Ghana is presented.

    Description: Die in den ersten zwei Teilen dieser Publikation detailliert beschriebenen tektonischen Aufschlussdaten und einige neuere Befunde werden nun analysiert. Die jeweiligen horizontaltektonischen Aussagen werden klassifiziert und sortiert. Unterschiedlich alte Einengungsphänomene sowie sinistrale und dextrale Relativbewegungen werden abgeleitet und graphisch dargestellt. Hinzu kommen entsprechende Auswertungen der aktuellen Geologischen Karten. Faltenstrukturen und zahlreiche Blattverschiebungen in unterschiedlichen Richtungen bilden sich ab. Die Verschiebungsweiten liegen bei mehreren Hundert Metern und häufig auch im Kilometerbereich. Maximal sind es 3,2 km. Auch Altersbeziehungen können abgelesen werden. Aus den sehr zahlreichen Beobachtungen werden fünf Beanspruchungsgruppen abgeleitet. Sie umfassen eine ehemals wirksame maximale Kompressionsrichtung und die entsprechend konjugierten dextralen und sinistralen Scherflächenscharen. Eine der Richtungsgruppen ist doppelt dokumentiert, subrezent und aus einer weit zurück liegenden Zeit. In einem nächsten Schritt werden die Gruppen zeitlich eingestuft, bei Berücksichtigung von Ergebnissen aus umliegenden Regionen. Sechs kompressive Deformationsereignisse werden rekonstruiert. Zuzuordnen sind sie dem Oberjura, der frühen Unterkreide, dem Unter- bis Mitteleozän, dem Oberoligozän, dem Untermiozän und dem plio-pleisto-holozänen Zeitabschnitt (Abb. 85, Tab. 2).
    Description: Abstract: The results of tectonic outcrop measurements in the southeastern Trier Embayment, which were particularly described in the two preceding parts of this publication, and additional new results will be analyzed now. The relevant horizontal stress data are classified and graded. Compressional phenomena of different ages and sinistral resp. dextral shear movements are listed and depicted graphically. Furthermore the actual regional geological maps are interpreted. Fold structures and several strike-slip faults of varying directions are obvious. The horizontal throws amount to several hundreds of meters, often the kilometer-scale is reached (maximum: 3.2 km). Relations of age can also be recognized. The huge number of observations allows the identification of five groups of strain. They all comprise a former direction of maximal horizontal compression and the appropriate conjugated dextral and sinistral shear plane sets. One of these directional groups is documented twice, it characterizes subrecent times and a quite old episode. The next step of investigation is the chronological rating of these groups. For this the results from adjacent regions are taken into consideration. Six events of compressive deformation are reconstructed. They can be assigned to Upper Jurassic, early Lower Cretaceous, lower to middle Eocene, upper Oligocene, lower Miocene and a time span of plio-pleisto-holocene age (fig. 85, tab. 2).

    Description: Unter der Stadt Mendig in der Vordereifel (Rheinland-Pfalz) ist in einer Tiefe von lediglich etwa 15 bis 25 m ein ausgedehntes Hohlraumsystem vorhanden. Die Hohlräume entstanden vorwiegend im 19. Jahrhundert und in der ersten Hälfte des 20. Jahrhunderts durch die bergmännische Gewinnung von Basalt im Kammer- Pfeiler-Bau. Das Tragwerk wird aus stehen gelassenen Basaltpfeilern und der Firste gebildet. Für die Standsicherheit der Hohlräume sind besonders die Elemente und Strukturen der Pfeiler von großer Bedeutung. Bei der ingenieurgeologischen Kartierung der Untertagehohlräume werden die Merkmale der Pfeiler in eigens für Mendig entwickelten Formblättern aufgenommen. Bisher wurde die Standsicherheit bzw. der Gefährdungsgrad der Pfeiler über den Vergleich mit element- und Strukturlisten bzw. -tabellen bestimmt. Im Rahmen der vom Landesamt für Geologie und Bergbau Rheinland- Pfalz vorgeschlagenen und betreuten Diplomarbeit von Frau Massenkeil, jetzt Amstutz (2012) wurde ein Datenbank-basiertes Punktesystem zur Gefährdungs - beurteilung der Pfeiler entwickelt. im vorliegenden Artikel werden die Entwicklung und Anwendung dieser Matrix vorgestellt. Bei Anwendung für das Blatt 01 der ingenieurgeologischen Karte von Mendig konnte eine 98-prozentige Übereinstimmung zwischen den beiden Methoden zur Gefährdungsbeurteilung erzielt werden.
    Description: Abstract: under the city of Mendig (rhineland-Palatinate) extensive underground mines remain from former mining activities of the 19th and 20th century. The cavities have a room-and-pillar structure in a shallow depth of about 15-25 m. During the geo - technical mapping of the underground cavities, the important structures and elements of the pillars are documented in forms, which have been developed especially for this project. So far, the geologist or engineer determined the stability and vulnerabi lity of the pillars by comparison with these forms. in her diploma thesis that was assisted by the State Department for Geology and Mining, Massenkeil (2012), now married Amstutz, developed a database-based point system for the risk assessment of the supporting pillars. in the article, the development and application of this matrix are presented. For the risk assessment a 98 percent conformity between the two methods could be proven.

    Description: Das Grundwasserleitersystem des Buntsandsteins, mit Mächtigkeiten in der Größenordnung bis etwa 300 m, ist für die Trinkwasserversorgung im Großraum Grünstadt von erheblicher wasserwirtschaftlicher Bedeutung. Eine systematische Erfassung und Dokumentation der Grundwasserverhältnisse in qualitativer und quantitativer Hinsicht liegt bislang nicht vor. Die bisher lokal verfügbaren Einzelbeobachtungen und wenigen Zeitreihen werden präsentiert und mit einander in Beziehung gesetzt. Statt der bisherigen, wasserwirtschaftlich auf die einzelnen Wassergewinnungsgebiete fokussierenden Betrachtung wird vorgeschlagen, den Buntsandstein als großräumig zusammenhängendes Grund wasserleitersystem zu verstehen und zu bewirtschaften. Hierzu sind entsprechende hydrogeologische Untersuchungen notwendig.
    Description: the aquifer system of the Bunter reach thicknesses in the order of about 300 m. it is of great importance for the drinking water supply in the Grünstadt area. A systematic collection and documentation of groundwater data in terms of quantity and quality has not yet been carried out. So far the locally available data and time series are presented and discussed in temporal and spatial relation. in the present the water management is focusing on the local water catchment areas. Based on the presented observations it is recommended to understand the Bunter as large scale hydraulically communicating aquifer system and to manage it in this sense. For this additional hydrogeological investigations are required.

    Description: The Rocknest aeolian deposit is similar to aeolian features analyzed by the Mars Exploration Rovers (MER) Spirit and Opportunity. The fraction of sand 〈150 micron in size contains approx. 55% crystalline material consistent with a basaltic heritage, and approx. 45% X-ray amorphous material. The amorphous component of Rocknest is Fe-rich and Si-poor, and is the host of the volatiles (H2O, O2, SO2, CO2, and Cl) detected by the Surface Analysis at Mars (SAM) instrument and of the fine-grained nanophase oxide (npOx) component first described from basaltic soils analyzed by MER. The similarity between soils and aeolian materials analyzed at Gusev crater, Meridiani Planum and Gale crater implies locally sourced, globally similar basaltic materials, or globally and regionally sourced basaltic components deposited locally at all three locations.

    Description: During 2012 we participated in 40 IVS sessions. As in the previous four years, we used the majority of the sessions that involved both Onsala and Tsukuba to do ultra-rapid dUT1 observations together with our colleagues in Tsukuba. We observed one four-station ultra-rapid EOP session together with Tsukuba, Hobart, and HartRAO. We also observed the RadioAstron satellite and several GLONASS satellites using the Onsala 25-m telescope. The highlight in 2012 was that our proposal to the Knut and Alice Wallenberg Foundation to establish a twin-telescope system at Onsala in accordance with the VLBI2010 recommendations was accepted.

    Description: Cells in microgravity are subject to mechanical unloading and changes to the surrounding chemical environment. How these factors jointly influence cellular function is not well understood. We can investigate their role using ground-based analogues to spaceflight, where mechanical unloading is simulated through the time-averaged nullification of gravity. The prevailing method for cellular microgravity simulation is to use fluid-filled containers called clinostats. However, conventional clinostats are not designed for temporally tracking cell response, nor are they able to establish dynamic fluid environments. To address these needs, we developed a Clinorotation Time-lapse Microscopy (CTM) system that accommodates lab-on- chip cell culture devices for visualizing time-dependent alterations to cellular behavior. For the purpose of demonstrating CTM, we present preliminary results showing time-dependent differences in cell area between human mesenchymal stem cells (hMSCs) under modeled microgravity and normal gravity.

    Description: The Norwegian Mapping Authority (NMA) has during the last few years had a close cooperation with Norwegian Defence Research Establishment (FFI) in the analysis of space geodetic data using the GEOSAT software. In 2012 NMA has taken over the full responsibility for the GEOSAT software. This implies that FFI stopped being an IVS Associate Analysis Center in 2012. NMA has been an IVS Associate Analysis Center since 28 October 2010. NMA's contributions to the IVS as an Analysis Centers focus primarily on routine production of session-by-session unconstrained and consistent normal equations by GEOSAT as input to the IVS combined solution. After the recent improvements, we expect that VLBI results produced with GEOSAT will be consistent with results from the other VLBI Analysis Centers to a satisfactory level.

    Description: This report includes an assessment of the network performance in terms of lost observing time for the 2012 calendar year. Overall, the observing time loss was about 12.3%, which is in-line with previous years. A table of relative incidence of problems with various subsystems is presented. The most significant identified causes of loss were electronics rack problems (accounting for about 21.8% of losses), antenna reliability (18.1%), RFI (11.8%), and receiver problems (11.7%). About 14.2% of the losses occurred for unknown reasons. New antennas are under development in the USA, Germany, and Spain. There are plans for new telescopes in Norway and Sweden. Other activities of the Network Coordinator are summarized.

    Description: VLBI2010 requires a receiver back-end to convert analog RF signals from the receiver front end into channelized digital data streams to be recorded or transmitted electronically. The back end functions are typically performed in two steps: conversion of analog RF inputs into IF bands (see Table 2), and conversion of IF bands into channelized digital data streams (see Tables 1a, 1b and 1c). The latter IF systems are now completely digital and generically referred to as digital back ends (DBEs). In Table 2 two RF conversion systems are compared, and in Tables 1a, 1b, and 1c nine DBE systems are compared. Since DBE designs are advancing rapidly, the data in these tables are only guaranteed to be current near the update date of this document.

    Description: VLBI2010 requires a feed that simultaneously has high efficiency over the full 2.214 GHz frequency range. The simultaneity requirement implies that the feed must operate at high efficiency over the full frequency range without the need to adjust its focal position to account for frequency dependent phase centre variations. Two feeds meet this specification: The Eleven Feed developed at Chalmers University. (For more information, contact Miroslav Pantaleev, miroslav.pantaleev@chalmers.se. The Eleven Feed, integrated with LNA's in a cryogenic receiver, is available as a product from Omnisys Instruments, info@omnisys.se). The Quadruple Ridged Flared Horn (QRFH) developed at the California Institute of Technology. (For more information please contact Ahmed Akgiray, aakgiray@ieee.org or Sander Weinreb, sweinreb@caltech.edu) Although not VLBI2010 compliant, two triband S/X/Ka feeds are also being developed for the commissioning of VLBI2010 antennas, for S/X observations during the VLBI2010 transition period, and to support X/Ka CRF observations. The two feeds are: The Twin Telescopes Wettzell (TTW) triband feed developed by Mirad Microwave. (For more information please contact Gerhard Kronschnabl, Gerhard.Kronschnabl@bkg.bund.de) The RAEGE (Spain) triband feed developed at Yebes Observatory. (For more information please contact Jose Antonio Lopez Perez, ja.lopezperez@oan.es)

    Description: This report summarizes the activities of the VLBI Analysis Center at the United States Naval Observatory for the 2012 calendar year. Over the course of the year, Analysis Center personnel continued analysis and timely submission of IVS-R4 databases for distribution to the IVS. During the 2012 calendar year, the USNO VLBI Analysis Center produced two VLBI global solutions designated as usn2012a and usn2012b. Earth orientation parameters (EOP) based on this solution and updated by the latest diurnal (IVS-R1 and IVS-R4) experiments were routinely submitted to the IVS. Sinex files based upon the bi-weekly 24-hour experiments were also submitted to the IVS. During the 2012 calendar year, Analysis Center personnel continued a program to use the Very Long Baseline Array (VLBA) operated by the NRAO for the purpose of measuring UT1-UTC. Routine daily 1-hour duration Intensive observations were initiated using the VLBA antennas at Pie Town, NM and Mauna Kea, HI. High-speed network connections to these two antennas are now routinely used for electronic transfer of VLBI data over the Internet to a USNO point of presence. A total of 270 VLBA Intensive experiments were observed and electronically transferred to and processed at USNO in 2012.

We principally continued to process European VLBI sessions using different approaches to evaluate possible differences due to various processing choices. Then VLBI solutions were also compared to the GPS ones as well as the ones calculated at co-located sites. Concerning the observational aspect, several tests were performed to identify the most suitable method to achieve the highest possible accuracy in the determination of GNSS (GLOBAL NAVIGATION SATELLITE SYSTEM) satellite positions using the VLBI technique.

    Description: Issues related to digital-backend (DBE) systems can be difficult to evaluate in either local tests or actual VLBI experiments. The 2nd DBE intercomparison workshop at Haystack Observatory on 25-26 October 2012 provided a forum to explicitly address validation and interoperability issues among independent global developers of DBE equipment. This special report discusses the workshop. It identifies DBE systems that were tested at the workshop, describes the test objectives and procedures, and reports and discusses the results of the testing.

    Description: Model-based Systems Engineering (MBSE) is an emerging modeling application that is used to enhance the system development process. MBSE allows for the centralization of project and system information that would otherwise be stored in extraneous locations, yielding better communication, expedited document generation and increased knowledge capture. Based on MBSE concepts and the employment of the Systems Modeling Language (SysML), extremely large and complex systems can be modeled from conceptual design through all system lifecycles. The Operations Revitalization Initiative (OpsRev) seeks to leverage MBSE to modernize the aging Advanced Multi-Mission Operations Systems (AMMOS) into the Mission Operations System 2.0 (MOS 2.0). The MOS 2.0 will be delivered in a series of conceptual and design models and documents built using the modeling tool MagicDraw. To ensure model completeness and cohesiveness, it is imperative that the MOS 2.0 models adhere to the specifications, patterns and profiles of the Mission Service Architecture Framework, thus leading to the use of validation rules. This paper outlines the process by which validation rules are identified, designed, implemented and tested. Ultimately, these rules provide the ability to maintain model correctness and synchronization in a simple, quick and effective manner, thus allowing the continuation of project and system progress.
