Sistematização do processo decisório em projetos de arquitetura, engenharia e construção baseado na TRIZ
Authors: Regalla Diana , Manfredi Naveiro Ricardo , Machado Corrêa Roberto
Published: June 2021

Os crescentes avanços tecnológicos no setor de Arquitetura, Engenharia e Construção (AEC) vêm causando mudanças nas relações funcionais e intensificando a competitividade entre os agentes dessa indústria, evidenciando a necessidade de organização do processo de projeto. Esse objetivo pode ser alcançado por meio de metodologias sistemáticas, uma vez que a falta de domínio do processo de criação pode promover resultados ineficazes. A Teoria da Solução Inventiva de Problemas (TRIZ) oferece uma abordagem sistemática, baseada no conhecimento tácito, direcionada ao processo criativo de solução de problemas. Propõe-se o uso da TRIZ nas etapas iniciais do processo para delimitar o espaço de busca por soluções, de forma sistemática e eficaz, integrando-se aos demais modelos de suporte ao projeto. Essencialmente, seu uso consiste na reestruturação do problema de um projeto específico em um problema genérico, cuja solução tenha princípios referenciais consolidados. O artigo apresenta a adaptação dessa teoria clássica, comumente utilizada no desenvolvimento de produtos para o setor de AEC, campo ainda não suficientemente explorado pela teoria, resultando na proposta de um instrumento para sistematizar o processo decisório diante das contradições de projetos. Um estudo de caso foi realizado, resultando em soluções práticas significativas, tanto para a validação do instrumento quanto para o projeto analisado.
Key and atlas to the genus Trichocera MEIGEN in Europe (Diptera, Trichoceridae)
Authors: Krzemiñska Ewa
Published: June 2021

The key presents all 59 species of the genus Trichocera MEIGEN which occur in Europe. Four subgenera are represented: Trichocera MEIGEN 1803 (five species), Metatrichocera DAHL 1967 (seven species), Saltrichocera KRZEMIÑSKA 2002 (35 species), and
Staryia KRZEMIÑSKA & GORZKA 2016 (13 species). The type material of two species, one from North America and one from Asia, are described (Trichocera columbiana ALEXANDER, 1927 and T. arctica LUNDSTRÖM, 1915), whose identities cause some problems and
whose presence in the northern regions of Europe is possible. Two new species are described, Trichocera ( Saltrichocera ) longa, n. sp., and T. (Staryia) oulankae, n. sp. Trichocera versicolor is resurrected from synonymy; T. limpidipennis
is synonymized with T. regelationis. There are separate keys to males and females; species are illustrated with camera pictures of diagnostic features: genitalia, antennae, and male tarsal claws, and additionally, wings and thoraces when only one sex is known, to enable further
search. The state of knowledge of the genus in Europe and in the world is discussed.

Authors: Simon Szabina , Simon Brigitta , Anda Angéla
Published: June 2021

The different nitrogen and phosphorus elements are prime constituents of the ecosystem and can exert a major effect on aquatic species and the overall ecological cycle. During our investigation we examined the nutrient leaching dynamics in decomposing leaf litter (stem and leaf blades) of Solidago virgaurea. We chose four different sampling sites during the winter period with different water temperatures in the Hévíz Lake and Hévíz canal. The bottles containing the plant material and water were incubated at natural temperatures and the fluid was removed at particular times. Water parameters such as pH level, conductivity, nutrients (ammonium and phosphates) were measured. In the case of Solidago leaf, we obtained higher values ​​for all parameters compared to the stem ones.
Coagulase-negative staphylococci in ewe udder surface and raw milk samples
Authors: Tonamo Andualem , Komlósi István , Petróczki Flóra Mária , Peles Ferenc
Published: June 2021

Coagulase-negative staphylococci (CNS) are among the major causes of subclinical mastitis in dairy ewe flocks. This has a financially significant impact on the ewe dairy sector and consumer health. The determination of the bacterial count, particularly CNS, is critical in terms of the quantity and quality of ovine milk. Thus, the purpose of this study was to quantify the CNS count in the udder surface and raw milk samples of the ewe, in addition to identifying CNS strains (n=8) collected from udder surface and individual raw milk samples by 16S rRNA gene sequencing. A total of 164 samples of udder surface and raw milk originated from four sheep farms were tested. The obtained values were compared between the different farms. Furthermore, values during 2018 and 2019 in the case of Farm I were compared. Significantly higher (p<0.05) average count was observed in udder surface samples taken from Farm I (2.8±1.0 lg CFU/cm2) than that of Farm III samples (2.3±0.6 lg CFU/cm2). In the case of individual raw milk, the higher value was observed in samples derived from Farm III (3.5±0.9 lg CFU/mL), while the obtained value was significantly lower (p<0.05) in samples originated from Farm IV (1.8±0.4 lg CFU/mL). In the bulk tank milk samples, the highest mean value was 5.3±0.4 CFU/mL, and there was no significant (p>0.05) variation between farms. Coagulase-negative staphylococci counts were decreased to a certain extent in both sample types tested during 2019 except for individual raw milk derived from the Tsigai breed. The correlation between the mean CNS counts of udder surface and individual raw milk was very weak (r=0.048). Staphylococcus simulans, Staphylococcus auricularis, and Staphylococcus equorum were identified by molecular sequencing and Staphylococcus simulans were the most frequently identified CNS species. A higher CNS count of bulk tank milk than individual raw milk indicates possible contamination during milking and storage. Therefore, further studies are required to investigate the other sources of bulk tank milk contamination to improve the hygienic quality of milk.
Evaluation of egg quality parameters of two Hungarian ostrich populations
Authors: Brassó Lili Dóra , Komlósi István
Published: June 2021

The aim of our study was to evaluate the quality parameters, porosity and weight loss of eggs deriving from the two most significant ostrich farms in Hungary. Quality parameters included weight, length, width, shape index, egg volume, surface area, circumference and shell volume.  The effect of storage conditions in both farms and the incubation technology on egg weight loss in farm “A” were also examined.  The research objective was to impart a comprehensive knowledge on egg quality parameters of the main ostrich populations in Hungary and to compare the trios and the farms with each other and the international literature. We could reveal significant differences between trios in all egg quality traits. In conclusion, the shorter and the narrower the eggs were, the more spherical shape they had.  Narrower eggs showed smaller surface area, volume, circumference and shell volume and vice versa. Eggs from farm “B” indicated significantly greater width, shape index, surface area, circumference and shell volume than farm “A”. A significant difference was observed in weight loss during storage between the farms.  Weight loss in farm “A” was a multiple of farm “B”. In farm “B” there was a weak, positive correlation between storage period and weight loss (r=0.22, P≤0.05), in farm “A” it was not significant (P=0.52). There was no relationship between the initial egg weight and weight loss either in farm “A” or farm “B” (P=0,21, P=0,69). A slight positive correlation could be noted between egg porosity and weight loss (r=0.24, P≤0.05). Pores count presented here was less than the international results. Poultry eggs contain the most pores at the blunt end, less via the equator and the least at the pointed end. In ostrich egg we found more pores via the equator against the blunt end. To draw more precise conclusions, further investigation should be carried out on porosity. Considering the fact that the length of storage period and the weight loss during incubation are in strict correlation with hatchability, we intend to extend our research aims to these traits.

Published: June 2021

Processing large amounts of data provided by automated analytical equipment requires carefulness. Most mathematical and statistical methods have strict application conditions. Most of these methods are based on eigenvalue calculations and require variables to be correlated in groups. If this condition is not met, the most popular multivariate methods cannot be used. The best procedure for such testing is the Kaiser-Meyer-Olkin test for Sampling Adequacy. Two databases were examined using the KMO test. One of them resulted from the sweet corn measured in the scone of the study, while the other from the 1979 book of János Sváb. For both databases, MSA (measures sampling adequacy) was well below the critical value, thus they are not suitable e.g. for principal component analysis. In both databases, the values of the partial correlation coefficients were much higher than Pearson’s correlation coefficients. Often the signs of partial coefficients did not match the signs of linear correlation coefficients. One of the main reasons for this is that the correlation between the variables is non-linear. Another reason is that control variables have a non-linear effect on a given variable. In such cases, classical methods should be disregarded and expert models better suited to the problem should be chosen in order to analyse the correlation system.
Análise de variância e testes de médias: um estudo aplicado em experimentos com variedades de algodoeiro e seleções de citrumelo / Analysis of variance and means tests: a study applied in experiments with cotton varieties and citrumelo selections

Published: June 2021

Um problema muito comum em experimentos agrícolas é a comparação de alguns tratamentos de interesse, de forma a determinar qual(is) o(s) melhor(es) tratamento(s), dentro dos objetivos da pesquisa. A maneira mais comum para tratar esse problema é por meio da análise de variância (ANOVA) dos dados do experimento, procedimento este responsável por decompor a variação total dos dados do ensaio dentre todas as fontes previstas de variação. O teste F global da ANOVA testa a hipótese nula de igualdade entre as médias populacionais dos tratamentos comparados, a qual também é chamada de hipótese de homogeneidade. Caso o teste F seja significativo, então rejeita-se a hipótese de homogeneidade e faz-se a aplicação de testes de comparação de médias, com o objetivo de investigar quais delas diferem entre si. Entretanto, um dos dilemas envolvidos com os testes de médias é justamente a sua aplicação apenas mediante um resultado significativo do teste F na ANOVA. Enquanto alguns pesquisadores defendem essa prática, outros acreditam que o teste de médias deve ser aplicado qualquer que seja o resultado do teste F. Nesse contexto, por meio da análise de um conjunto de dados referente ao peso de capulho de variedades de algodoeiro e da análise de um conjunto de dados referente à eficiência produtiva de seleções de citrumelo, foi confrontado o resultado do teste F global e os resultados dos seguintes procedimentos de comparação de médias de tratamentos, comumente aplicados na área agrícola: teste de Tukey e teste de Duncan. A partir da análise foi possível concluir que nem sempre há concordância entre o resultado do teste F e os resultados dos testes de médias. Para a variável peso de capulho das variedades de algodoeiro, enquanto o teste da ANOVA apresentou resultado não significativo, ao nível de significância de 5%, o teste de Duncan acusou diferenças entre as médias comparadas, ao mesmo nível de probabilidade. Já para a variável eficiência produtiva de citrumelos, enquanto o teste F global apresentou resultado significativo, ao nível de 5%, o teste de Tukey não acusou diferenças entre as médias comparadas, ao mesmo nível de significância.

Em diversas situações do cotidiano é comum perceber esperas que geram filas, algumas são rápidas, mas outras ocorrem além do planejado, sobretudo, quando se trata de atendimento em redes públicas como é o caso do laboratório municipal, localizado na cidade de Parauapebas no estado do Pará. Este local foi escolhido como objeto de estudo principalmente por ser o único laboratório público da cidade e claramente perceptível as longas filas devido a demanda alta por atendimento e baixa capacidade do sistema em absorvê-la em curto tempo. A Lei 13.460 de Junho de 2017 dispõe dentre os direitos básicos dos usuários aos serviços públicos que os mesmos tenham previsão do tempo de espera para atendimento. Portando este trabalho foi desenvolvido aplicando os conceitos de teoria de filas com o propósito realizar uma análise do sistema de atendimento e propor uma solução para minimizar a espera dos pacientes ao realizar exames.
A lichenometrical study of snow patch variation in the Frederikshåb district, South-West Greenland, and its implications for studies of climatic and glacial fluctuations
Authors: Pitman G.T.K
Published: June 2021

This report describes firstly the methods used to determine local growth rates of the species Rhizocarpon geographicum and the confidence that can be put in such estimates of substrate age based on lichen diameters. Secondly, mean Rhizocarpon geographicum diameters in former snow patch zones were sampled and non-random patterns of colonization were observed. Two models were constructed to explain these colonization patterns in terms of the change of the perennial snowline with height against time. Hence mean annual temperatures back to 1680 were predicted from the models for Frederikshåb. Lastly a correlation is shown between local mean annual temperature changes in the historical period, glacial fluctuations, and estimates of temperature obtained from the lichen colonization models.
The geology and mineralisation of the Mesters Vig area, East Greenland. Part I. General geology. Part II. Blyklippen occurrence, structure and its influence on ore deposition
Authors: Bondam J , Brown H
Published: June 2021

An account of The Geology and Mineralisation of the Mesters Vig area. It will be best expressed by dividing the descriptions into three different parts. Part I includes the general geology of the Mesters Vig area. It has been prepared by J. Bondam, Geological Survey of Greenland, Copenhagen. The description is a brief summary of the stratigraphy within the area, as it has been established by E. Witzig, Switzerland, former geologist of the Northern Mining Company). To this summary new field and laboratory observations have been added. The geological map has been published through the courtesy of the Northern Mining Company, Copenhagen. Part II deals with the structural relations of the Blyklippen veins, and their influence on ore deposition. The study has been accomplished by H. Brown, Northern Mining Company, during the years 1953 and 1954. Part III will be published later in connection with these two papers. This part will deal with the paragenesis of the ore depositions at Blyklippen.
Llandovery trllobites from Washington Land, North Greenland
Authors: Lane P.D
Published: June 2021

Twenty-eight forms of trilobites obtained from a single block of Lower Silurian limestone are described. Three new species – Stenopareia somnifer, Cyphoproetus? alyo and Harpidella (Harpidella?) helenae – are erected. The fauna is considered to indicate an upper Lower Llandovery or lowest Middle Llandovery age; it is compared in particular with other faunas from similar lithology.
The Fiskenæsset complex, West Greenland. Part IV. Chemistry of sulphide minerals
Authors: Bishop F.C , Smith J.V , Windley B.F
Published: June 2021

The textures and chemistry of sulphides were investigated in 63 rocks from the Fiskenæsset complex, West Greenland, by light microscopy, electron microprobe, and X-ray diffraction techniques. Sulphides are found disseminated throughout the layered sequence, being especially concentrated in the ultramafic zone and in ultramafic lenses in the higher zones. Sulphide phases are restricted to the Cu-Fe-Ni-Co-S system – pentlandite, pyrrhotite, chalcopyrite, pyrite, millerite, heazlewoodite, cobalt-pentlandite, polydymite, godlevskite, violarite, cubanite, and digenite. Most sulphides occur interstitially as rounded globules often containing significant quantities of oxides. Some aggregates occur as inclusions in silicate or chromite, as ragged stringers between other phases, or with scalloped intercumulus textures. Subsolidus reactions are common; fine-scale intergrowths of pentlandite-pyrite, chalcopyrite-pyrite, chalcopyrite-cubanite, pentlandite-heazlewoodite and pentlandite-godlevskite-polydymite occur. Euhedral pyrite is found in the anorthosites and chromitites. Pyrite-millerite appears to be an equilibrium pair in some rocks. Weathering affects the major phases in the following order: pyrrhotite > chalcopyrite > pentlandite. Temperature stability limits for several of the phases, equilibrium phase assemblages, and textures of the sulphide intergrowths, all indicate that the sulphides have re-equilibrated to low temperatures. The common pyrite-pentlandite assemblage places a 230°C upper limit, and the digenite composition places a 125°C lower limit, on the temperature of equilibration. A marked sulphide stratigraphy which correlates with silicate chemistry is present in the Fiskenæsset complex. There is a systematic progression from Ni,Fe-rich sulphides in the lower ultramafic and mafic zones to Cu,S-rich assemblages in the upper, more felsic zones. Sulphide fractionation exhibiting some of these features is also found in other layered igneous intrusions. The similarity of the Fiskenæsset sulphides with those in other intrusions, coupled with the unlikely possibility of derivation of the sulphides by assimilation or metasomatism, implies that the sulphides were derived from the original magma.
Paleocene gastropods from Nûgssuaq, West Greenland
Authors: Kollmann H.A , Peel J.S
Published: June 2021

This catalogue illustrates 257 gastropod taxa from Paleocene deposits on the Nûgssuaq peninsula, West Greenland. Mesogastropods and neogastropods dominate, with 103 and 86 taxa respectively. There are 38 archaeogastropod taxa and 29 of Euthyneura, while one operculum is of unknown systematic position. Taxa are named at the generic level; no new names are introduced. Most of the fauna was collected from a single bed (Sonja Lens) within the Sonja Member of the Agatdal Formation. Faunal composition within this bed indicates a mixed assemblage with representatives from a variety of environments ranging from terrestrial (1 taxon) to shallow and deep marine, on soft and hard substrates.
On sand samples from the west coast of Greenland. Part I. An examination of the contents of minerals in a number of sand samples from the northern part of the Holsteinsborg District
Authors: Thomsen B
Published: June 2021

Forty one samples of sand from rivers and beaches from three fjords north of Holsteinsborg were analysed. On the basis of the minerals of the heavy fractions the samples may be divided into three groups: group E derived from enderbitic gneiss with the main minerals, hornblende, hypersthene, and diopside, while garnet plays a secondary role only; group G chiefly derived from granulitic rocks where garnet is dominating with sillimanite and rutile as characteristic components, while the content of hornblende, hypersthene, and diopside is relatively low and, finally, group M that with the main minerals, hornblende, hypersthene, diopside, and garnet and a slight content of sillimanite and rutile shows that the sample material derives from enderbitic as well as granulitic rocks.
An enigmatic cap-shaped fossil from the Middle Cambrian of North Greenland
Authors: Peel J.S
Published: June 2021

Nyeboeconus robisoni gen. et sp. nov., is described from the Middle Cambrian Henson Gletscher Formation of western North Greenland. Some authors have interpreted similar shelIs as chondrophorine hydrozoans or invertebrate fossils of uncertain systematic position. The coiled, cap-shaped shell and the presence of an internal plate, or pegma, suggest, however, that this new form is the second genus to be described of the Family Enigmaconidae MacKinnon, 1985 (Mollusca, Class Helcionelloida), otherwise known only from rocks of similar age in New Zealand.

The Danish Lithosphere Centre in 1995
Authors: Larsen H.C
Published: June 2021

The Danish Lithosphere Centre (DLC) is funded by the Danish National Research Foundation and was established in 1994 (Larsen, 1995). In 1995 DLC undertook major field geological investigations in both West and East Greenland, and within the Ocean Drilling Program (ODP) drilling on the continental shelf offshore East Greenland. More than 50 national and international researchers were involved in DLC field geological programmes, and 25 researchers from ODP member countries took part in the offshore drilling operations. The general aims and scope of these activities as well as the continued development of the Centre are summarised below. Preliminary results of the 1995 work programmes are given by van Gool et al., Larsen et al. and Brooks et al. (all this report).
An intrusion breccia with associated ultrabasics from Sermersût, South-West Greenland
Authors: Bondesen E
Published: June 2021

A detailed 1 :500 map and a description of some peculiar breccia structures are presented. The breccia was emplaced in the Precambrian basement rocks, consisting mainly of granodioritic gneisses and amphibolites. The structures of the breccia are highly irregular consisting of lots of connected dyke-shaped bodies. More distinct dykes of the breccia matrix run out into the gneisses. The breccia itself consists of a matrix of mineral fragments and numerous inclusions of rock fragments, the majority of which are of exotic origin. Associated with the breccia are some larger soapstone bodies of which smaller fragments are found in the breccia. The breccia is thought to have been emplaced by gas drilling in connection with the intrusion of the soapstones in a solid/subsolid stage. The chronological significance of the breccia is emphasized.
The pattern of folding in an area of migmatites between Neria and Qasigialik fjords, South-West Greenland
Authors: Kalsbeek F
Published: June 2021

A geometrical analysis of mesoscopic structures (foliation planes, lineations, minor fold axes) in an area of migmatites is presented. In spite of the intensive migmatization of the rocks the observations fit into a more or less regular pattern, which is interpreted as the result of three superimposed folding phases, the first of which was roughly contemporaneous with an important phase of metamorphism and the second with the migmatization of the rocks in the area. For the interpretation of great circle diagrams use has been made of a computer program to find a great circle of best fit, the pole of which is used as the most plausible fold axis in a number of subareas.
L'évolution du socle précambrien dans la région de Qagssimiut, Groënland méridional
Authors: Ayrton S.N , Burri M
Published: June 2021

The rocks of the Qagssimiut area, South Greenland, belong, apart from a few late dolerite dykes, to the Precambrian shield. Their history was found to be very complex. An orogenic period affected formations mainly composed of quartzites and amphibolitic schists which now occupy but a very small percentage of that area. These rocks, having been submitted to at least two periods of deformation (during which a set of folds with a NW~SE trend, and a major, younger NE-SW set were developed), were subsequently intruded by massifs and plugs of ultrabasic material, which are very much more widely preserved. Widespread granitisation then occurred; in particular, the pre-existent rocks were (partly) transformed into granite, which is by far the principal component of the Qagssimiut area. The processes apparently took place in tranquil conditions. Basic intrusion also takes the form of sheets and dykes, concentrated mainly in the southern parts of the area. Some of these sheets are conspicuously veined and replaced by granite or aplite. The striking characteristics of this phenomenon, which involves static replacement and progressive consumption of basic material by acid, are described in some detail. The contrast between basic and acid material is remarkable, as is the alternation of phases of basic intrusion and granitisation, which occurred under conspicuously stable conditions. The emplacement of small massifs of homogeneous, pink or white microgranite preceded the Gardar period, characterised by the intrusion of dykes (lamprophyres, dolerites, trachytes, porphyries) and block-faulting. A long hiatus separated the end of the Gardar period from the next event, the (Tertiary?) intrusion of two generations of dolerite dykes. They are fresh and never faulted. Quaternary phenomena are mainly related to the activity of the ice-cap, whose traces are ubiquitous.
Precambrian organic compounds from the Ketilidian of South-West Greenland. Parts I and II
Authors: Pedersen K.R , Lam J
Published: June 2021

Well preserved Ketilidian sedimentary rocks from South-West Greenland, about 2000 million years old and containing macroscopic and microscopic fossils, have been examined for organic material. The results of the work on the extractions from a coal-graphite layer are presented together with a short description of the local geology around this layer. Straight chain and branched paraffins, mono-, di-, or polycyclic aromatic hydrocarbons, borneol, camphor and other monoterpenoid compounds, fatty acids and methyl esters of fatty acids are present in samples from the coal-graphite layer, together with other organic substances as yet unidentified. Pristane, phytane and other isoprenoid hydrocarbons have been found in small amounts. The presence of these organic compounds indicates a biological origin of the coal-graphite layer. Besides the coal-graphite other sediments (dolomites and quartzites) from the succession have yielded organic material. Further work on these samples and on the coal-graphite is in progress.
Homogeneous deformation of the gneisses of Vesterland, South-West Greenland
Authors: Watterson J
Published: June 2021

Structural development of the migmatitic gneisses of the Vesterland area is described first by reference to successive fold episodes (FCF3) and then by reference to the estimated pattern of three-dimensional homogeneous strain. Mylonite zones, up to 2 km in width, are located along attenuated steep limbs of relatively open F3 folds. In acid gneisses F. folds are usually isoclinal, with axial planes and axes parallel to those of F1 folds. In basic gneisses F2 folds are of relatively open style and both axes and axial planes differ from those of F1 folds. The macroscopic penetrative fabric of the gneisses is of the L-S type in which three mutually perpendicular axes can be recognised on a variety of scales, the axes corresponding to the principal axes of the strain ellipsoid. The strain ellipsoid corresponding to deformation in the acid gneisses, as estimated from the disposition of discordant acid veins, is of prolate type, with deformation path (k) approximately 17, and axial ratios 1:3:100. The relationship between homogeneous deformation and varying styles and attitudes of F1 and F2 folds is discussed.
Danian foraminifera from Nûgssuaq, West Greenland. With special reference to species occurring in Denmark
Authors: Hansen H.J
Published: June 2021

The stratigraphy of the Lower Danian Kangilia Formation and the Upper Danian Agatdal Formation cropping out on the north coast and in the central part of Nugssuaq is discussed. The local abundance of marine fossils in the Agatdal Formation is explained as due to redeposition and transportation before the shales of the Agatdal Formation were dehydrated and compressed. On the basis of planktonic foraminifera viz. Globoconusa daubjergensis, Globigerina compressa, Subbotina triloculinoides and Subbotina pseudobulloides the age of the Agatdal Formation is assigned to Upper Danian. The foraminiferal fauna of the Agatdal Formation is composed of 57 species. The affinity of the fauna to European Paleocene faunas is stronger than to North American faunas. The biostratigraphical zonation of Danian deposits based on the occurrence of planktonic foraminifera is discussed. In the systematic part the fauna is described and illustrated. Atlanta primigenia, Ravn, 1918, originally described as a heteropod, is shown to be a foraminifer belonging to the genus Cornuspiroides. By measurement of the proloculus diameter it is shown that the distribution of megalospherie proloculi of Bulimina midwayensis remains constant from the Upper Maastrichtian to the Middle Selandian. The same character is used to distinguish Bulimina rosenkrantzi from Bulimina trigonalis and Bulimina thanetensis. On the basis of studies of wall ultrastructures of Subbotina triloculinoides it is shown that the genus Subbotina is well distinguished from the genus Globigerina. The wall of Subbotina triloculinoides is bilamellar with an overlying laminated crust like the one found in Globorotalia menardii, which phenomenon is illustrated by transmission eleetron micrographs. The genera Allomorphina, Quadrimorphina and Pallaimorphina are diseussed. The latter is shown to be a valid genus. Allomorphina is inhomogeneous with respect to species with and without tooth-plates. Allomorphina paleocenica is an allomorphinid without tooth-plate and should accordingly be referred to a genus other than Allomorphina. The author's limited material prevents the establishment of a new genus. In Alabamina rosenkrantzi n. sp. is found a secondary closure of the foramina. Lower Tertiary alabaminas show preferred sinistral coiling. Granulate monolamellar species earlier referred to the genus Eponides are placed in a new genus Paralabamina which belongs to the family Alabaminidae. The genera Gyroidina, Gyroidinoides and the group of species morphologically close to "Gyroidina" soldanii are shown to be well distinguished in apertural characters. The genus Gyroidinoides is transferred to the family Anomalinidae, in which also Gyroidina and "Gyroidina" soldanii belong. Eight new species are described. Two belong to the genus Lenticulina, two to Fissurina, one to Rosalina, one to Pallaimorphina, one to Alabamina and one to Ceratobulimina.
The colour and luminescence of tugtupite (beryllosodalite) from Ilímaussaq
Authors: Povarennykh A.S , Platonov A.N , Tarashchan A.N , Belichenko V.P
Published: June 2021

Tugtupite, Na4 [BeAlSi4O12] Cl, is a mineral with bright pink colour and yellow-orange UV-luminescence. The visible region of the spectral absorption curves and the luminescence spectrum of tugtupite from the Ilímaussaq alkaline massif (South Greenland) were studied. Calculated and experimental values of vibrational frequencies of different molecular ions were compared, and it was established that the luminescence of tugtupite is caused by S2 molecular ions occupying the position of Cl ions in the crystal structure. These ions are also the cause of the colour of tugtupite, probably in combination with other, thermically less stable, radiation centres.
Fossil picrodendroid fruit from the Upper Danian of Nûgssuaq, West Greenland
Authors: Koch B.E
Published: June 2021

Rosenkrantzia picrodendroides n.gen. et n.sp., based on 4. 7 specimens of fossil fruit in very good preservation, is described. The fruit was a nut (or drupe), with a thick pericarp of primitive anatomy. It is l-locular, containing one fully developed seed; about half of the specimens also contain remnants of a second aborted seed. The seed is pendulous from an apical placenta and has a long longitudinal raphe. Hilum is distal, chalaza basal. The original ovary can be reconstructed: l-locular with min. two ovules, pendulous from the distal placenta, anatropous. The fully developed seed consists mainly of two thick, interfolded cotyledons with no distinct endosperm. The taxonomical investigation includes a study of fruits of two of the recent Picrodendron species. A phylogenetic conclusion is advanced which supports the position of the Picrodendraceae in the order Juglandales. The taxonomic position of Rosenkrantzia appears to lie somewhere between the Cupuliferae ( Quercus group) and Juglandales, or in palaeontological terms, between the Dryophyllum and Dewalquea groups.
Contributions to the interpretation of the Fennoscandian Border Zone
Authors: Baartman J.C , Christensen Ole Bruun
Published: June 2021

The interpretation of reflection seismic data in the Kattegat has revealed the combined effect of tectonic movements which took place from Pre-Jurassic through recent times.A continuation of the Fennoscandian Border Zone in Scania occupies a broader belt of more deep-seated basement-related fault blocks in the Kattegat area, but fades away towards NW. A mainly Jurassic sill striking SSW from Anholt separates the Kattegat area in partially open basins of Cretaceous deposition. In the 0resund several large north-northwest striking basement-related faulted blocks appear to be associated with the tectonics of the Fennoscandian Border Zone.The most prominent features relating to the structures and the geological history of the Fennoscandian Border Zone have been outlined.Some details connected with the Pre-Quaternary outcropping for the area have been evaluated. Katholm-erratics containing "Cyrena" fossils from the Kattegat area are not of Lower Oligocene age, but from Upper Jurassic and are most probably originate from the Anholt area.One of some structural models for northwestern Europe has been advanced for verification. Parts of the Fennoscandian Border Zone have perhaps been affected by large-scale dextral fractures.
Petrographic study of Danian limestone from eastern Denmark (Core Copenhagen TUBA 13)
Authors: Nielsen Erik Broe
Published: June 2021

Based on the investigations of thin sections, peel prints and X-ray radiographs, quantitative and qualitative data on the carbonate constituents of the Danian limestone from København are presented.The Danian limestone was classified according to both the petrographic nomenclature proposed by Folk (1962) and Dunham (1962) and to the occurrence of microborings.It is believed that on the basis of the results of the present study the problems concerning the wave and current intensities, as well as the relative depths of the formation of the Danian limestone, might be solved, through future petrographic investigations.
Bidrag til Danmarks senglaciale Flora og Fauna
Authors: Hartz N
Published: June 2021

Efter at A. G. Nathorst i 1870 havde paavist Resterne af Istidens Flora ved Alnarp i Skaane, fandt han i 1871 i Selskab med Jap. Steenstrup de første Glacialplanter i Danmark i Nærheden af Kjøbenhavn, under de af Steenstrup tidligere undersøgte Skovmoser. Saa vidt vides har Steenstrup aldrig nærmere publiceret, hvilke Lokaliteter der da undersøgtes, men paa Grundlag af Samtaler med ham og støttet til hans efterladte Samlinger, der opbevares paa Mineralogisk Museum, antager jeg, at Vintappermosen og de srnaa Moser ved Rudersdal Kro og Holte have været de vigtigste Findesteder. Paa Etiketterne nævnes desuden Jægersborg, og i et Brev til mig meddeler Prof. Nathorst, at saa vidt han mindes, bleve de første arktiske Planter fundne netop i Nærheden af Jægersborg.
En østjydsk Israndslinje og dens Indflydelse paa Vandløbene. Tekstbind
Authors: Harder Poul
Published: June 2021

Materialet til den foreliggende Afhandling er indvundet ved Undersøgelser i Terrainet i Somrene 1902-1905. I Hovedsagen har Arbejdsgangen været den, at der er begyndt længst imod Nordøst, og derfra er Undersøgelserne efterhaanden udstrakt videre og videre imod Sydvest, dog med stadige Revisionsture tilbage i det tidligere undersøgte Terrain. Da Profiler, stærkt stenede Overflader o.s.v. i Løbet af kort Tid kan forandres ret betydeligt, skal følgende mere detaillerede Oplysninger om Tidspunktet for Iagttagelserne i de forskellige Egne her anføres. I 1902 var kun den sydlige Del af Grenaa Halvøen Genstand for Undersøgelse, men i 1903 udstraktes denne saa langt imod Sydvest som til Aarhus Dalen, samtidig med at der foretoges supplerende Arbejder i Grenaa Halvøen, saaledes at Undersøgelsen af Strækningen fra Aarhus Dalen til Grenaa bragtes til en foreløbig Afslutning. Foruden forskellige Oversigtsture foretoges i 1904 en Undersøgelse af Terrainet nærmest Vest og Nord for Grenaa, og derefter paabegyndtes Arbejdet i Egnen Nordvest for Horsens. I 1905 underkastedes først Lilleaa Dalen en mere indgaaende Bearbejdelse, men største Delen af Somren anvendtes dog til at gennemføre den det foregaaende Aar paabegyndte Undersøgelse af Horsens Egnen samt Terrainet nærmest Nord herfor.

Marsken ved Ribe
Authors: Jessen A
Published: June 2021

I Marskegnene skelner man som bekendt imellem Marsken, den lavtliggende, frugtbare Engjord af marin Oprindelse, og Geesten, det højere liggende, sandede og mindre frugtbare Land, der for største Delen bestaar af glaciale Aflejringer. Hver af disse Grupper indeholder dog saa forskelligartede Dannelser, at man i geologisk Henseende nødes til en mere detailleret lnddeling. Paa medfølgende Kort over Marskens Udbredelse i Egnen mellem Esbjerg og Rigsgrænsen skelnes der imellem følgende Aflejringer: Diluviet, det oftest bakkede Højland (Bakkeøer), bestaaende af Glacialdannelser; Hedesletterne, der breder sig mellem Bakkeøerne og for den overvejende Del er af senglacial Alder; Ferskvands-Alluviet, for største Delen bestaaende af Tørvemoser, men ogsaa af Ferskvandsdynd og, især langs Aaløbene, af Ferskvandssand; Flyvesand, dels som et nogenlunde jævnt Dække over andre Aflejringer, dels som udprægede Klitter; Strandsand og Strandgrus , der optræder dels som almindelige Strandvolde, dels som tørlagte Sandvader, hvor Sandet kan være enten rent og skarpt eller mere og mindre klægblandet ; Marsken, der kan variere fra meget fed til meget sandblandet Klæg; og endelig er paa Kortet angivet Vaderne, saavel Sandvader som Slikvader samt de større Sejlløb og Render i Vadehavet.
Om grænsen mellem Saltholmskalk og Lellinge Grønsand og nogle bemærkninger om inddelingen af Danmarks ældre Tertiær
Authors: Harder Poul
Published: June 2021

I mange Aar - lige fra Johnstrup's Tid - har der ikke været Lejlighed til at undersøge Profiler, naaende ned i den prækvartære Undergrund under Kjøbenhavn. Det er saa meget mere beklageligt, som man her kunde vente, i hvert Fald paa nogle Steder, at finde Lellinge Grønsand 1) hvilende paa Saltholmskalk 2) og faa Lejlighed til at studere Enkelthederne i Lagfølgen paa dette meget interessante og ogsaa meget omdiskuterede Sted i den danske Lagrække, hvor man endog en Tid lang har villet trække Grænsen mellem Kridtids- og Tertiæraflejringerne.
Sur le Placement géologique du Danien
Authors: J. P.J. Ravn
Published: June 2021

Depuis quelques années la question du placement du Danien est à l'ordre du jour des discussions géologiques dans notre pays. Faut-il rapporter le Danien au système crétacé, comme on l'a fait jusqu'ici, ou devra-t-on le considérer comme formant la partie la plus ancienne du Tertiaire? La discussion de ce problème a été suscitée par M. K. Brünnich Nielsen; se basant sur notre connaissance actuelle du Danien et de sa faune il a cru devoir se rallier à la proposition avancée il y a longtemps déjà par M. De Grossouvre, visant à rapporter le Danien au Tertiaire. Comme d'autres géologues danois ont été gagnés également à ce point de vue, il a paru nécessaire de reprendre la question pour la considérer de plus près et pour s'y orienter, et ceci d 'autant plus que l'on commence à s'apercevoir que les vues de ces géologues danois exercent une certaine influence sur des géologues étrangers qui ne connaissent pas par eux-mêmes les conditions telles qu'elles se présentent ici en Danemark. Tant qu'il ne s'agissait que de »transporter« simplement le Danien d'un système à un autre la chose en elle-même ne présentait guère d'intérêt scientifique ; mais il en est tout autrement dès que l'on s'applique, comme cela a été fait dernièrement, à établir un parallèle entre nos formations daniennes et certaines formations tertiaires de l'étranger connues de longue date. C'est alors que la question devient brûlante, et le travail considérable que représente un effort pour pénétrer dans le fond de la question s'impose comme indispensable. C'est d'un tel effort que les pages suivantes rendront compte.
Metoder til Undersøgelse af Lerets fysiske Egenskaber
Authors: Mertz Ellen Louise
Published: June 2021

Sammen med Grus, Sand og organiske Aflejringer danner Lerarterne Jordskorpens løse Jordlag, hvis Alder og Dannelsesmaade det stedse har været en af Geologiens Hovedopgaver at faa udredet. Interessen har dog hovedsagelig samlet sig om Lagenes eventuelle Fossil- eller Stenindhold, og kun rent undtagelsesvis er Spørgsmaalet om Lerets egne Egenskaber traadt i Forgrunden. Imidlertid har Lerret og de øvrige løse Jordlag jo ikke alene Værdi som geologiske Blade i Jordens Historie; de danner Bygningsværkernes Fundamenter, de er Grundlaget for Organismernes Vækst, og de senere Aars store Krav til Jordens Ydeevne nødvendiggør et stedse grundigere Kendskab til deres Sammensætning og Konsistens. Ud fra Geologien har der derfor skilt sig to nye Videnskaber: Agrogeologien og Geotekniken; de har ikke til Formaal at udrede Jordlagenes Alder, men deres Anvendelighed, og de har derfor erstattet Studiet af Lagenes Fossilindhold med en lige saa grundig Undersøgelse af Jordarternes Egenskaber og hele Natur. Hensigten med og Anvendelsen af de opnaaede Resultater ligger den egentlige Geologi - og dermed ogsaa denne Afhandling - ret fjernt; men selve Resultaterne og Vejen, der fører til dem, har dog nogen Interesse for den geologiske Videnskab, thi gennem Kendskabet til et Jordlags Konsistens opnaar man et stærkt tiltrængt Supplement til den rent geologiske Undersøgelse af Laget, og dette vil særlig være af stor Værdi i de hyppige Tilfælde, hvor Forsteningsmaterialet er utilfredsstillende eller ganske svigter.

Lillebeltsler og London Clay
Authors: Mertz Ellen Louise
Published: June 2021

I Aaret 1909 omtalte nu afdøde Professor N. V. Ussing i sin Artikel i Tidsskriftet ”Ingeniøren”: ”Et Par Bemærkninger om Jordbundsforholdene paa Overfartsstederne” Forholdene ved Lillebelt paa følgende Maade: ” ... Helt anderledes er Jordbundsforholdene i Lillebælt. Dettes smalleste Del er en dybt nedskaaret Rende, der ikke alene gaar tværs gennem Istidsdannelserne, men endda et Stykke ned i disses Underlag; og det sidste er ikke Kridt eller Kalksten, men ”plastisk Ler ”. Hvad vi betegner med dette Navn, er en ensformig, overmaade fast, sandfri Lerart, absolut uigennemtrængelig for Vand, men i Modsætning til Morænemergelen tilbøjelig til langsomt at blødes op til en sej Vælling, hvor den ved Jordoverfladen er i stadig Berøring med Vand, hvorved voldes de bekendte Skred. I Konsistens (og for øvrigt ogsaa i Dannelsestid) svarer det plastiske Ler meget nær til det i lngeniør kredse maaske bedre kendte London Clay … ” Denne sidste Bemærkning er det sikkert, der har foraarsaget den blandt Ingeniører gældende Anskuelse, at det plastiske Ler i Lillebælt, der i det følgende vil blive kaldt Lillebæltsler, og London Clay er nøje sammenhørende, ikke alene i Alder, hvad jo har mindre Interesse for Teknikere, men ogsaa i Konsistens, d.v.s. i Kornstørrelse, i Henseende til Plasticitet , Vandsugningsevne o.s.v.
Magnetische Messungen im südwestlichen Dänemark
Authors: Ebert A
Published: June 2021

Auf Vorschlag von Direktor Dr. Victor Madsen genehmigte das dänische Unterrichtsministerium die Ausführung magnetischer Messungen in Dänemark in den Jahren 1929- 31. Die Ausgaben wurden 1929 aus den für Geländearbeiten der Danmarks geologiske Undersögelse vorgesehenen Mitteln bestritten , im Jahre 1930 und 1931 besonders bewilligt. Diese Vermessungen wurden im Sommer 1929, im Herbst 1930 und im Frühjahr 1931 ausgeführt und erstreckten sich auf Jütland von der Reichsgrenze bis zur Linie Varde-Vejle und im Ost en bis zur Linie Faaborg-Odense-Bogense auf Fünen. Ein besonderer Dank gebührt dem Danske Meteorologiske Institut, das in hilfreicher Weise die täglichen Z- und H-Variationen zu meiner Verfügung gestellt hat. Eine in jeder Beziehung t atkräftige Unterstützung erfuhr ich durch Herrn Direktor Dr. Victor Madsen, dem ich meinen ganz besonderen Dank ausspreche.
Kridtformationen i Sjælland. Terrænet mellem København og Køge, og paa Saltholm
Authors: Rørdam K
Published: June 2021

I den største Del af Danmark ere de præglaciale Dannelser dækkede af mægtige glaciale og postglaciale Lag og ere i Almindelighed ikke tilgængelige for direkte Undersøgelse. Dette er saaledes ogsaa Tilfældet i den vestlige Del af Sjælland, hvor Kridtformationens Overflade ligger dybt under Havets Niveau, og hvor Glacialformationens Lag oftest have en Mægtighed af 200 Fod og derover. I den østlige Halvdel af Sjælland ere Forholdene gunstigere, særlig i de midterste Partier, og foruden de fra gammel Tid kendte Iagttagelsespunkter for Kridtformationen i Faxe Bakke og Stevns Klint. findes der mellem København, Roskilde, Ringsted og Køge en Strækning, hvor Kridtformationens Lag gaa op over Havets Niveau, og hvor K vartærformationens Dannelser kun have ringe Mægtighed, saa at Kridtformationens Lag i forskellige aabne Udgravninger kan gøres til Genstand for Undersøgelse.

Danmarks Mineraler
Authors: Bøggild O.B
Published: June 2021

Den danske Mineralverden er, som man kan tænke sig, ikke særlig rig; Antallet af forskellige Mineraler er ikke stort (ca. 50), og der er ikke blandt Forekomsterne nogen, der udmærker sig ved store og smukke Krystaller, eller er videre iøjnefaldende paa anden Maade. Alligevel frembyder de dog forskelligt af Interesse, og jeg haaber, at en Sammenstilling af vor Viden paa dette Omraade dog vil have en vis Værdi.Hovedmaterialet til dette Arbejde har været paa den ene Side hvad jeg har kunnet finde anført i Litteraturen og paa den anden Side de i Universitetets mineralogiske og geologiske Museum værende Mineraler. Hvad Litteraturen angaar, kan der maaske nok findes Angivelser rundt omkring i de ret betydelige geologiske Arbejder, som jeg ikke har været opmærksom paa, og der vilde maaske ogsaa ved Gennemgang af andre Museer og Samlinger kunne findes andre Forekomster end de her i Afhandlingen nævnte; imidlertid haaber jeg dog, at der ikke skulde være udeladt noget mere væsentligt.
