SUBJECTS OF SCIENTIFIC AND METHODOLOGICAL SUPPORT OF EXPERTISE IN THE SPHERE OF INTELLECTUAL PROPERTY
Authors: Kirin R.
Published: June 2021

The article is devoted to the definition, based on the analysis of scientific publications and the prescriptions of domestic legislation, the subject composition of forensic relations and relations in the field of intellectual property, which directly or indirectly participate in the regulation, management, development, use and improvement of scientific and methodological support of forensic expert activities in the field of intellectual property.
It has been established that at the legislative level the following are identified:
– subjects of organizational relations of departmental scientific and methodological support of forensic expert activity;
– subjects of coordination and publishing relations of interdepartmental development of forensic examination;
– subjects of the relationship of attestation and state registration of methods of conducting forensic examinations.
It is proposed to distinguish between the following types of object-subject warehouses: 1) objects that need support (forensic expertise, forensic examination, expert proceedings); 2) objects that meet the needs of the corresponding level of action (scientific and methodological benefits); 3) entities in need of support (forensic institutions, forensic experts) 4) entities that provide for the needs (ministries, advisory bodies, forensic experts). It has been suggested that the subject requiring collateral can be simultaneously the subject performing this collateral.
The expediency is argued and the differentiation of subjects of scientific and methodological support of forensic expert activity in the field of intellectual property on the following integration levels is proposed:
– national (regulatory, managerial, judicial);
– sectoral;
– production (state, private);
– territorial;
– public (permanent, temporary)
– self-regulating;
– direct (personal, collective, employee, manager)
– functional (organizational, managerial, controlling, security, executive, reporting).
EXPERTISE OF FINE ART WORKS AS OBJECTS OF COPYRIGHT: GENERAL PROVISIONS AND APPROACHES TO THE SOLUTION OF EXPERT PROBLEMS
Authors: Kisil N.
Published: June 2021

When considering disputes over copyright infringement on works of fine art, it becomes necessary to establish the fact of the use of works. In Ukraine, the study of properties, features, patterns of creation and use of works of art as objects of copyright is included in the subject of expertise in the field of intellectual property.
Based on generalization of expert practice, the main tasks of forensic examination of works of fine art have been identified. They are:
– definition in the research object of the characteristics of the copyright object;
– determination in the object of research or part of it (including the name) of the signs of originality and creative nature;
– establishment of the fact of reproduction of a work or part thereof, which has an independent meaning; establishment of the fact of processing of a work.
As a result of the research, approaches have been developed to solve expert problems related to works of fine art. The main approaches are highlighted by examples of the study of animated characters and paintings.
The following algorithm of actions is proposed when establishing the fact of reproduction of works of fine art - characters:
1) to analyze the properties and characteristics of the objects under study;
2) highlight the elements that relate to the elements of the form and content of the work;
3) identify common and distinctive features; conduct its comparative analysis;
4) to find out the nature of changes in the attributes of these objects;
5) to establish whether the coinciding attributes form a set that is sufficient to identify a certain object.
Based on the results of the study, the author concludes that when establishing the fact of reproduction or processing of a work of painting, special attention should be paid to the analysis of coincidences and differences in the elements of the form and content of the studied works. If you find matches in the elements of the form, it is necessary to determine whether these elements are individualizing for this work (whether they are original). When it is established that the found coincidences in the elements of the studied works of painting are due to the reflection of objective reality (properties and features of the objects of the image), the use of generally accepted (standard) techniques and methods of creation, there will be no reason to conclude that there is a reproduction or processing of the work. Such elements do not individualize the work of a particular author (they are not original) and, according to the provisions of copyright, can be freely used in the works of different authors.
Women’s voices of protest: Sonia Sanchez and Nikki Giovanni’s poetry
Authors:   Institute of Philology Borys Grinchenko Kyiv University, Yakovenko Iryna
Published: June 2021

The paper explores contemporary African American women’s protest poetry in the light of the liberation movements of the mid-20th century – Black Power, Black Arts Movement, Second Wave Feminism. The research focuses on political, social, cultural and aesthetic aspects of the Black women’s resistance poetry, its spirited dialogue with the feminist struggle, and undertakes its critical interpretation using the methodological tools of Cultural Studies. The poetics and style of protest poetry by Sonia Sanchez and Nikki Giovanni, whose literary works have received little scholarly attention literary studies in Ukraine, are analyzed. Protest poetry is defined as politically and socially engaged verse which is oppositional, contestatory and resistant in its subject matter, as well as in the form of (re)presentation. Focusing on political and societal issues, such as slavery, racism, segregation, gender inequality, African American protest poetry is characterized by discourse of resistance and confrontation, disruption of standard English grammar, as well as conventional spelling and syntax. It is argued that militant poems of Sonia Sanchez are marked by the imitations of black speech rhythms and musical patterns of jazz and blues. Similarly, Nikki Giovanni relies on the oral tradition of African American people while creating poetry which was oriented towards performance. The linguistic content of Sanchez and Giovanni’s verses is lowercase lettering for notions associated with “white america”, obscenities targeted at societal racist practices, and erratic capitalization, nonstandard spacing, onomatopoeic syllables, use of vernacular as markers of Black culture. The works of African American women writers, which are under analysis in the essay, constitute creative poetic responses to traumatic history of African American people. Protest poetry of Sonia Sanchez and Nikki Giovanni explicitly express the rhetoric of Black nationalism and comply with the aesthetic principles of the Black Arts movement. They are perceived as consciousness-raising texts by their creators and the audiences they are addressed to. It is argued that although protest and resistance poetry is time- and context-bound, it can transcend the boundaries of historical contexts and act as timeless texts.
Humans and animals in Bernard Werber’s novel «Tomorrow the Cats» (Demain les Chats)
Authors:   Nizhyn Mykola Gogol State University, Poltoratska Alla
Published: June 2021

Characters of animals have been present in the literature since its emergence up to present times. However, at the end of the XIX and the beginning of the XXI century they gained growing interest of literary critics, philosophers, historians, anthropologists, biologists and ecologists that gives scope for studying characters of animals as an interdisciplinary phenomenon. The purpose of the present paper is to study the position of animals in human culture, society, and the relationship between people and animals. It is worth noting that the contemporary authors tend to abandon the dominant position of a person and reveal one of the modern issues, namely, the vulnerability of all creatures before the cruelty of the world. One of such novels is “Tomorrow the Cats” written by the famous French writer, Bernard Werber. The main idea of the novel is to depict a person through lens of an animal. In his novel, Bernard Werber shows the world through cats’ eyes and predicts the proper evolution of humanity. A new perspective of human-animal interaction is the leveling differences between them. In the novel animals can understand language, read, perceive information, predict, behave like a person having a purpose to make friends with people. Bernard Werber points to the rights and protection of animals of humiliations they have been experiencing throughout human history. Contemporary human being has to understand: neither man should rule over nature, nor nature should rule over man. The writer’s vision of the future relationship between species and the conditional symbiosis of animals for their salvation is examined in the article. Besides, new transformations of human-animal relations are studied in the paper and the reasons for mentioned changes are outlined. After all, against the background of the war, the author depicts the contemporary problem of human interaction with the outside world, in which the threat to all creatures is not only looting, but also a plague of rats seeking domination in the city. For the common salvation of animals they are joining to humans. So the author interprets in such a way the image of animal as species closed to man. Thus, Bernard Werber represents changes in human perception of the animal, characterized by man’s desire to worry about the lives of other species. The author seeks to warn a man describing a number of situations in which a man is cruel to the world around him and to his own species. The writer seeks to warn people of the terrible consequences of their actions in order to protect them. Bernard Werber says that the mission of people on the earth is changing, they should worry not only about their existence, but also about existence of the world around them.
Acoustic Properties of Metal-Organic Frameworks
Authors: Li Zhi-Gang , Li Kai , Dong Li-Yuan , Guo Tian-Meng , Azeem Muhammad , Li Wei , Bu Xian-He
Published: June 2021

Metal-organic frameworks (MOFs) have attracted significant attention in the past two decades due to their diverse physical properties and associated functionalities. Although numerous advances have been made, the acoustic properties of MOFs have attracted very little attention. Here, we systematically investigate the acoustic velocities and impedances of 19 prototypical MOFs
via
first-principle calculations. Our results demonstrate that these MOFs exhibit a wider range of acoustic velocities, higher anisotropy, and lower acoustic impedances than their inorganic counterparts, which are ascribed to their structural diversity and anisotropy, as well as low densities. In addition, the piezoelectric properties, which are intimately related to the acoustic properties, were calculated for 3 MOFs
via
density functional perturbation theory, which reveals that MOFs can exhibit significant piezoelectricity due to the ionic contribution. Our work provides a comprehensive study of the fundamental acoustic properties of MOFs, which could stimulate further interest in this new exciting field.

K/Ar age determinations
Authors: Larsen O
Published: June 2021

In the spring of 1968 we finished setting up and testing the K/Ar dating apparatus at Mineralogisk Museum. A small number of GGU samples were dated during the summer months. Since September a fair amount of time has been spent on testing the suitability of atomic absorbtion spectrophotometry for determining K, Rb and Sr. These efforts, however, have not yet been very successful although a considerable amount of experience has been gained. In November and December our main efforts were concentrated on the first attempts at using the solid source mass spectrometer (Atlas CR 4) at Fysisk Laboratorium II, H. C. Ørsted Institute, for isotope analysis on Rb and Sr.
On the applicability of magnetic prospecting for chromite in the Fiskenæsset region, West Greenland
Authors: Ghisler M , Sharma P.V
Published: June 2021

The chromite deposits of the Fiskenæsset region belong to a metamorphosed igneous complex of stratiform type occurring in the basement gneiss unit of older Precambrian age in West Greenland. Short descriptions and modal compositions of the different rock types are given together with the results of magnetic measurements on 60 rock samples (data shown in tables 1-5). On the basis of known geology and rock susceptibilities different models are discussed with respect to the applicability of both an airborne and a ground magnetometer survey. It is concluded that the susceptibility contrasts involved are sufficient for locating favourable host rocks by aeromagnetic survey, but direct magnetic prospecting for chromite horizons predominantly occurring within anorthosites may not be feasible.

Notes on the glacial geology of eastern Milne Land, Scoresby Sund, East Greenland
Authors: Funder S
Published: June 2021

During the summer of 1969 field work was begun with the aim of establishing a general chronology of Quaternary events in the Scoresby Sund region. This summer the work was concentrated on the eastern part of Milne Land (fig. 1). The region under consideration is shown in fig. 9; it comprises a coastal zone of low rounded mountains (400-600 m) composed of crystalline rocks, and a central zone of high mountains (1500 m) of alpine topography where Tertiary basalts rest on a basement of crystalline rocks. South-east of a line from Mudderbugt to Charcot Havn the bedrock is Mesozoic sandstone. Milne Land is bordered to the east and south by the comparatively shallow (400-600 m deep) waters of Scoresby Sund and Hall Bredning; on all other sides this large island is bordered by over-deepened fjords (800-900 m deep - see hydrographic chart in Thorson, 1934). In the central part of Milne Land an ice cap - Puderne - is found.
Preliminary account of the mapping of the Mesozoic formations of south-east Jameson Land
Authors: Surlyk F , Bromley R.G , Asgaard U , Pedersen K.R
Published: June 2021

In the 1970 field season, the programme of mapping Jameson Land (Birkelund & Perch-Nielsen, 1969; Bromley et al., 1970) was continued with·a study of the Hurry Fjord region and the area between Mønselv and Raukelv on the south coast (fig. 6). The geology of the west coast of Hurry Fjord has been studied previously by Hartz (1896), Harris (1926, 1937), Rosenkrantz (1934) and Aldinger (1935), and certain parts of the succession are known in detail. During the 1970 field season, however, special study was made of the phytopalaeontology of the Kap Stewart Formation (K.R.P.), the ichnology of the Neill Klinter Formation (R.G.B. & U.A.) and the stratigraphy of the Kap Biot Formation and the beds overlying the Neill Klinter Formation (F.S.). These special studies will be published later. A full report of the mapping must wait until a more detailed topographic map is available for the publication of the geological map.
Preliminary report of the mapping of the basalts of parts of Milne Land and Gåseland
Authors: Watt W.S , Watt M
Published: June 2021

In the summer of 1970 field work on the Tertiary basalts was concentrated in the southem part of Milne Land and in the inner part of Gåseland based on three camps in each of these areas (fig. 8). The work was a direct continuation of the investigations from the two previous years (Watt, 1969 & 1970) and included part of the area aiready visited by Wenk (Wenk, 1961). Due to a late start of the season only 13 sections were traversed distributed with 9 on Milne Land and 4 on Gåseland. From each camp one or more basalt sections were examined in detail and in addition a couple of rapid traverses were made during helicopter reconnaissance. Particular emphasis was placed on attempts to correlate the different basalt sections.

Regional geology of early Precambrian high-grade metamorphic rocks in West Greenland. Part 1: Kângnaitsoq to Ameralik
Authors: Windley B.F
Published: June 2021

Within this region three types of area are distinguished: 1. Amphibolite-grade areas which did not reach a granulite grade. 2. Granulite-grade areas. 3. Amphibolite-grade areas, many of which have been retrogressed from the earlier granulite grade. The main rocks are hypersthene-biotite gneisses, biotite-hornblende gneisses, amphibolites with or without orthopyroxene, sillimanite mica schists, rare marbles, skarns and quartzites, layered calcic anorthosites, a great variety of meta-ultramafic rocks including rare zoned talc lenses, abundant pegmatites, several generations of dolerite dykes locally amphibolitised by deep-seated fauIts. The fold structure of the region is characterised by abundant large-scale interference patterns. The history of the region is interpreted on the basis of a deformed cover/basement relationship, all major units being now mutually conformable.
The geology of southern Jameson Land
Authors: Surlyk F , Birkelund T
Published: June 2021

In 1971 the mapping of southem Jameson Land was completed by four field parties (comprising the authors, K. Birkenmajer, J. H. Callomon, R. G. Bromley, Ulla Asgaard, Lise Alkærsig, B. Buchardt Larsen and S. R. Larsen). The work was a direct continuation of mapping along Hurry Inlet in 1970 (see Surlyk et al., 1971). The Hurry InIet area was the only part of southern Jameson Land well known from earlier investigations. Thus, Rosenkrantz (1929, 1934), Spath (1932), Harris (1937) and Callomon (1961) described the different parts of the sequence exposed in Neill Klinter, while Lower Cretaceous occurrences in south Jameson Land were known from the works of Aldinger (1935) and Spath (1947). The Triassic deposits, underlying the Kap Stewart Formation and referred to the Klitdal Formation by Rosenkrantz (1929), were investigated in detail by K. Birkenmajer during the 1971 season and compared to the lithological units of Scoresby Land. The results are given by Perch-Nielsen et al. (this report) and are therefore not dealt with here.
The geology of the Fiskenæsset region
Authors: Kalsbeek F , Myers J.S
Published: June 2021

In 1955 Grønlands Geologiske Undersøgelse (The Geological Survey of Greenland, GGU) started the systematic mapping of the west coast of Greenland. Up to 1963 the work was concentrated in the southernmost part of Greenland, around Nanortalik:, Julianehåb and Ivigtut, from 1958 to 1963 from a base camp, 'Dyrnæs' near Narssaq. In 1964 the base camp was moved northwards to a site near Frederikshåb, 'Mellembygd', and from 1964 to 1968 the region around Frederikshåb was mapped, as far north as Frederikshåbs Isblink. In 1969 the base camp was moved still further north, to 'Midgård', 15 km north-north-east of Fiskenæsset, and in 1970 mapping in the Fiskenæsset Region commenced. Mapping of the area between Frederikshåbs Isblink and Fiskenæsfjorden (an area of about 2500 km2) is now almost finished, and a simplified map is presented on plate 1. This paper attempts to give an outline of the geology of the area.
Petrography of gneisses south of Bjørnesund in the Fiskenæsset region
Authors: Tomas J.R
Published: June 2021

The mapping of the area south of Bjørnesund, begun in 1970, was completed during the summer field season of 1971. During the routine mapping special attention was paid to the gneiss complex. The detailed petrography and chemistry of the gneisses will be the topic of a further paper, but this report gives a brief description of the distinguishing petrographicai characters of the gneiss types. Several types and sub-types of gneisses have been distinguished according to their varying mineral composition, structure, texture and grade of migmatisation. Only those gneiss types and sub-types that occur in units which can be followed for more than 200-500 m are described; xenoliths and small patches of different rock types, however lithologically different, are not.
The structure and stratigraphy of the anorthosite complex in the area north of Bjørnesund, near Fiskenæsset
Authors: Walton B.J
Published: June 2021

Over the area extending about 15 km north of the inner part of Bjørnesund, near Fiskenæsset (fig. 16), numerous conformable layers of anorthositic rocks occur within gneisses. The rocks have been metamorphosed in the amphibolite and granulite facies, and affected by five episodes of folding. Only minor intrafolial and isoclinal folds have been recognised from the early phases (F1 and F2) but major isoclinal folds which were initially recumbent with NE trending axes were produced by F3 folds. These were subsequently refolded by F4 and F5 fold phases which produced major and minor tight to open upright folds with axial planes striking BSE and NE respectively. It is possibie that the anorthosites have been affected by all five episodes of folding, but only F3 to F5 have been recognised in these rocks with certainty.
Precambrian structures of the Ikorfat peninsula, Agto region, West Greenland
Authors: Skjernaa L
Published: June 2021

A supracrustal sequence of biotite gneisses, light coloured garnet-biotite gneisses (metasediments) and metabasite rocks is bounded to the north-west and south-east by basement rocks of biotite (± hornblende) gneisses and metabasites. The supracrustal sequence lies in the core of a major F3 synform. Metabasite horizons are used as marker horizons to elucidate the structure of the area. Hornblende-granulite subfacies metamorphism accompanied the F3 folding; later retrograde metamorphism only affected the rocks along master joints and thrusts. Structural analysis of the basement rocks indicates at least two folding phases older than the F3 folding of the supracrustal sequence; the supracrustals also show minor folds of a fourth phase.

Regional mapping and palaeomagnetic and geological investigations in the Scoresby Sund region, central East Greenland
Authors: Henriksen N
Published: June 2021

The fifth season of the five-year mapping programme in the Scoresby Sund region was carried out during July and August. A tent base-camp was established at the head of Fønfjord at the entrance to Hjørnedal (see fig. 5). The base served as an operation centre for three helicopters and one motor cutter and throughout the season a regular connection between the base and Mesters Vig airport was maintained with a small fixed-wing aircraft. The expedition numbered 44 persons comprising 14 two-man geological parties and supporting personnel. Ten parties mapped in the crystalline complex around the fjords Vestfjord, Fønfjord and Gåsefjord. One party mapped the western part of the Tertiary basalt area and one party made palaeomagnetic profiles in the basalts. Geochronological investigations in the crystalline areas were carried out by one party and another party undertook glaciological studies of some of the major glaciers in the western part of the region.

Hydrochemical investigations on river water in West, South and East Greenland
Authors: Asmund G
Published: June 2021

Hydrogeochemical investigations have been concerned with the analysis of heavy metals dissolved in stream and river water. The concentrations of metals like Cu, Pb, Ni, Cr, and Cd are however usually below the level of detection by commonly used water analysis methods. For this reason, and to overcome some of the problems connected with the transportation of water from Greenland to Copenhagen, i.e. contamination of the samples by the container or absorption of metals on the container surface, a new method of analysis was developed two years ago at the Danish Atomic Energy Commission's Research Establishment, Risø.
K/Ar and Rb/Sr age determinations on Precambrian crystalline rocks in the Inglefield Land – Inglefield Bredning region, Thule district, western North Greenland
Authors: Larsen O , Dawes P.R
Published: June 2021

FolIowing field investigations in North Greenland in 1971 by one of us (P.R.D.) a selection of rocks was made available for age dating work. The first results - K/Ar whole-rock ages on dolerites - suggest that the basal part of the unmetamorphosed Thule Group is at least 1200 m.y. old (Dawes et al., 1973). This note reports the first results of adating programme carried out by O. L. at the Institute for Petrology, Vniversity of Copenhagen and is concerned with the age of the underlying and older crystalline basement complex. Further work is continuing particularly on a Rb/Sr whole-rock isochron. Supplementary sample collecting is scheduled to take place in the summer of 1974.
A zircon age from gabbro-anorthosite inclusions in the gneisses of the Angmagssalik area, South-East Greenland
Authors: Nunes P.D , Steiger R.H , Bridgwater D
Published: June 2021

Age determinations were made on 3 zircon fractions extracted from gabbroanorthosite inclusions which occur as tectonically dislocated pods in quartzofeldspathic gneisses on the eastern end of Kitak island, South-Bast Greeniand (fig. 5). The anorthosites were selected for study because they are derived from a lithologically distinctive suite of rocks found over a large part of the Archaean craton of the North AtIantic area (Bridgwater et al., 1973b). While there is no evidence that all the anorthosites of this type are contemporaneous their formation appears to require special conditions in the ernst and they are thus likely to be a useful stratigraphic tool. Furthermore the coarse-grained refractory nature of these rocks means that they retain their lithological identity during later tectonic, anatactic and metasomatic events to a far greater degree than the quartzofeldspathic, semipelitic and amphibolitic units making up the major part of the gneiss complex in which the anorthosites occur.

The basalt area between Steward Ø and Kap Dalton, and the inland region south of Kap Dalton, is one of the least known parts of central East Greenland. The folIowing remarks are aresult of a one day photo-reconnaissance flight over the area, made with the object of providing sufficient photographic material to show the most important tectonic features (fig. 21). No samples were collected.
Late Precambrian acritarchs from the Eleonore Bay Group and Tillite Group in East Greenland
Authors: Vidal G
Published: June 2021

Thirty-five samples from the late Precambrian Eleonore Bay Group and Tillite Group in the Caledonian fold belt in Bast Greenland were investigated for acid-resistant microfossils. Eleven samples yielded acritarchs. As a rule the state of preservation of the recovered acritarchs is poor, as aresult of slight metamorphism. Within the Eleonore Bay Group, identifiable acritarchs were recovered from four samples from the Limestone-Dolomite series, one sample from the Multicoloured series, one sample.from the upper Quartzite series, two samples from the lower Quartzite series and one sample from the Argillaceous-Arenaceous series. Relatively well preserved acritarchs occur in two samples from the slightly disconformably overlying Tillite Group. Some of the acritarchs recovered have a wide geographic distribution and apparently a narrow stratigraphic range in the upper Precambrian. Preliminary results indicate a Late Riphean age for the uppermost Eleonore Bay Group (Limestone-Dolomite series and Multicoloured series) and a Vendian age for at least the lower investigated parts of the Tillite Group.
Palynological evidence for the age of Tertiary basalts and post-basaltic sediments at Kap Dalton, central East Greenland
Authors: Soper N.J , Costa L.I
Published: June 2021

Small outliers of sedimentary rocks overlying the Tertiary basalts of the northern Blosseville Kyst are preserved in down-faulted areas at Kap Dalton and Savoia Halvø (Kap Brewster) (Watt et al., this report). They are of particular interest in that their age establishes a younger limit for the period of effusive vulcanity on this sector of the East Greenland continental margin.
Investigations of Quaternary geology on the west coast of Disko, central West Greenland
Authors: Donner J
Published: June 2021

During summer 1976 the coasts of Nordfjord, Mellemfjord and Disko Fjord were investigated. All three fjords were oulets or large valley glaciers moving towards the outer western coast of Disko. Some of the till matenal transported by the glaciers came from the inner parts of the island, as seen for instance in Nordfjord, where the matenal contains gneiss from the outcrops some way up in Stordal, the valley NW of the head of Nordfjord. However, the drift in the fjords consists mostly of the local basalt. During the retreat of the glaciers lateral moraines and kame terraces were deposited on the slopes. In Nordfjord they are at about 100 m above sea level and at about the same altitude in the inner parts of Disko Fjord. No clear end moraines connected with the lateral formations can be traced, but thick drift near the mouth of Mellemfjord, at Narssârssuk on the southern shore and at Kûggssuaq on the northern shore, may form remnants of an end moraine. Similar thick drift occurs also on the southern and northern shores ofthe innermost parts of Kangikerdlak in Disko Fjord and at the mouths of some smaller valleys.

The airborne radiometric survey in West Greenland, initiated in 1975 (Secher, 1976), was completed in 1976 with the completion of the region between Søndre Strømfjord and Frederikshåbs Isblink - an area of 42 000 km2. This made a total of 100 000 km2 thus investigated in West Greenland (Steenfelt et al., 1977). The programme was carried out as a collaboratioin between GGU and the Research Establishment, Risø. The aircraft, a Britten-Norman Islander, was chartered through Greeillandair Charter AIS. Field operations were carried out from the GGU field station at Søndre Strømfjord Air Base. Equipment and methods used during the radiometric survey were as in 1975 (Secher, 1976). Follow-up field work on the ground will take place during the next few years.
Foraminiferal evidence for the East Greenland Current during the Oligocene
Authors: Birkenmajer K , Jednorowska A
Published: June 2021

This note summarises results of a microfaunal investigation of nine samples collected in 1971 from the Eocene-Oligocene Krabbedalen Formation, Scoresby Sund, central East Greenland. Six of the samples were taken from a continuous section at Krabbedalen and the remaining three from poor, isolated exposures 0.5 km east and 2.5 km south of Krabbedalen, and 4 km south of Søstrene (Birkenmajer, 1972, fig. 13). The microfauna includes 37 foraminiferal species, predominantly arenaceous benthos (29 species), with single specimens of calcareous benthos (7 species) and one specimen of calcareous plankton.
Laboratory error in C14 dating of East Greenland shell material
Authors: Funder S
Published: June 2021

Nine samples of subfossil, Holocene bivalve sheIIs from scattered localities in the East Greenland fjord zone (70° 30'-74°N) were submitted for C14 dating at the Teledyne Isotopes Laboratories, New Jersey, U.S.A., in 1975. The ages obtained seemed to be much too young compared with earlier datings from the region and consequently the laboratory offered to re-date the samples. Thus, the results were not released in the annua! compilation of C14 dating of GGU material (Weidick, 1976). Material was selected again from the same sample bags and submitted. The only obvious difference between the two sets of samples was that the best preserved sheIIs had been disposed of in the first dating.
Igneous rocks in the Proterozoic platform of eastern North Greenland
Authors: Jepsen H.F , Kalsbeek F
Published: June 2021

The Proterozoic sandstones of the Inuiteq Sø Formation (Jepsen, 1971) and the Norsemandal Sandstone (Adams & Cowie, 1953) contain numerous sills, sheets and dykes of dolerites and other intrusive rocks. Locally, the intrusions may make up 75 per cent of the total section along some fjord walls. The sequence is overlain by basaltic vo1canics, locally up to 1300 m thick. The igneous rocks have been the main object of our field work and they are briefly described below. The intrusive rocks have been studied earlier by Koch (1925), Ellitsgaard-Rasmussen (1950) and Jepsen (1969); the occurrence of basaltic volcanics was reported and mapped by the Greenarctic Consortium in 1969 (personal communication to GGU).
A gravity map of Peary Land, North Greenland
Authors: Forsberg R
Published: June 2021

During the summer af 1978 the Geodetic Institute, Copenhagen, established a regional gravity network as a minor part of the surveying programme, with a combination of barometric, triangulation and doppler-derived heights as vertical control. A preliminary map of bouguer anomalies with 20 mgal contours is shown in fig. 32. Terrain-corrected bouguer anomalies will be avilable at a later stage, when the digital terrain models to be used for plotting height curves on the coming ortho-photo maps are completed. It is important to note that the terrain corrections for some stations in very rugged topography might raise the anomalies considerably, up to the order 10 mgal.
Outline of the Nagssugtoqidian mobile belt of East Greenland
Authors: Bridgwater D , Myers J.S
Published: June 2021

The Nagssugtoqidian mobile belt is a 240 km wide zone of deformation and plutonic activity which cuts across the Archaean craton of East Greenland. The belt was established 2600 m.y. ago by the formation of vertical E-W shear zones and the syntectonic intrusion of basic dykes. Tectonic activity along the E-W shear zones was followed by the emplacement of tonalitic intrusions, the Blokken gneisses, 2350 m.y. ago in the central parts of the mobile belt. The emplacement of the Blokken gneisses was accompanied and followed by further emplacement of basic dykes. These are synplutonic in the centre of the mobile belt but are emplaced into more rigid crust in the marginal areas of the belt and in the Archaean craton to the north and south. During a second major tectonic and thermal episode circa 1900 m.y. ago, the region was deformed by thrusting from the north. In the southem part of the mobile belt the earlier steep shear zones are cut by shear zones dipping gently northwards in which rocks are downgraded to greenschist facies. The grade of metamorphism increases northwards and shear zones are replaced by open folds with axial surfaces which dip gently northwards. The increasing ductility in the centre of and northem part of the belt is associated with the intrusion of charnockitic plutons and their granulite facies aureoles. Regional uplift occurred before the intrusion of high level post-tectonic plutons of diorite and granite 1550 m.y. ago.
Some charnockitic rocks in the Nagssugtoqidian of West Greenland
Authors: Hansen B.F
Published: June 2021

Several charnockite bodies occur in the Precambrian gneiss terrain between Nordre Strømfjord and Agto, West Greenland. The country rocks are mainly enderbitic gneisses, granodioritic gneisses and almandine-sillimanite bearing schists. The largest charnockite body forms the mountain of Kingigtoq between Nordre Strømfjord and Gieseckes Sø. The body has been deformed by at least two fold phases prior to the sinistral simple shear of the Nordre Strømfjord shear zone. Most parts have a gneissose structure, but undisturbed porphyritic textures also occur. The main rock types are charnockite, quartz mangerite and quartz jotunite. The charnockites in the Agto area may be of anorthosite kindred because of chemical similarities: Fe tot./Fe tot. + MgO is about 0.9, average K/Rb is 358, and K2O/SiO2 is high. Average U is 0.52 ppm and average Th is 11.0 ppm. Metamorphism subsequent to intrusion has led to assemblages with ubiquitous gamet and hornblende, commonly accompanied by ortho- and clinopyroxene. Gamet and clinopyroxene stably coexist in felsic charnockites in the Agto archipelago, but on Kingigtoq only in mafic members of the suite. Element distributions indicate an equilibration temperature of 750°C - 850°C, at 8-10 kb solid pressure.
A new Phanerozoic carbonatite complex in southern West Greenland
Authors: Secher K , Larsen L.M
Published: June 2021

The airborne radiometric survey carried out in 1975 and 1976 in West Greenland (Secher, 1976, 1977), was followed in 1977 by field work on the ground. Areas with anomalous high radioactivity, detected during the airborne work, were examined using helicopter and handborne scintillometers. Between the valleys Arnangarnup kua and Sarfartoq, 60 km SSW of Søndre Strømfjord Air Base, a cluster of anomalies were shown to be related to a conspicuous area of carbonatite rocks now referred to as the Sarfartoq carbonatite complex (fig. 18).
Observations on the late Archaean Qôrqut Granite, Qôrqut, Godthåbsfjord, southern West Greenland
Authors: Burwell A.D.M , Friend C.R.L
Published: June 2021

The Qôrqut Granite is an elongate body, 50 km Iong and up to 18 km wide, emplaced in the core of a broad NNE-SSW trending antiform (McGregor, 1973; Bridgwater et al., 1976). In the central part of the pluton are large areas of homogeneous granite but elsewhere the body consists of a complex association of granite and migmatised enclaves. The roof zone of the granite consists of gently-dipping sheets of granite and pegmatite separated by rafts of country rock, the latter retaining their original orientation well down into the main body of the granite. In the southern part of the pluton, two phases of granite may be recognised, an early biotite-rich phase and a later, more leucocratic, biotite-poor phase.
The North Greenland fold belt in eastern Johannes V Jensen Land

Published: June 2021

This report concerns that part of the North Greenland fold belt in north Peary Land (Johannes V. Jensen Land) which lies east of Polkorridoren (the glacier filled depression between Frigg Fjord and Sands Fjord) and north of the Harder Fjord fault (fig. 40). The rocks forming the fold belt are mainly Lower Palaeozoic quartzites, carbonates, arkoses and shales, which are an extension of the Hazen Trough that stretched through the Queen Elizabeth Islands of Canada and across northern Greenland. Because of the northward increase in deformation and metamorphic grade, it is convenient to subdivide the region into a southerly, less deformed, area in which a stratigraphical sequence ean be established, and a northerly area in which only lithological units can be mapped. The dividing line corresponds to that, north of which, 'way-up' criteria cannot be used owing to the masking of the sedimentation structures by a pervasive schistosity. This line runs approximately from the northern end of Paradisfjeld to Bliss Bugt.

Hiện nay, tất cả các trung tâm đăng kiểm xe cơ giới đang áp dụng quy trình kiểm tra chất lượng hệ thống phanh khi ô tô ở chế độ không tải. Mặc dù quy trình đánh giá này vẫn đảm bảo chất lượng hệ thống phanh ô tô theo tiêu chuẩn hiện hành TCN 224-2001, tuy nhiên nó vẫn tiền ẩn nguy cơ tai nạn giao thông do sự sai khác về chế độ tải trọng khi ô tô chuyển động trên đường. Bài báo này giới thiệu về tính toán, thiết kế bệ thử phanh có chất tải cho ô tô nhằm hạn chế tối đa sự sai khác hiệu quả phanh giữa thử nghiệm trên bệ thử và trên đường. Nguyên tắc thiết kế là sử dụng cơ sở vật chất có sẵn tại các trung tâm đăng kiểm xe cơ giới và không thay đổi bố trí mặt bằng các dây truyền. Hai xy lanh thủy lực được liên kết với cầu xe ô tô thông qua dây đai sẽ tạo ra tải trọng tối đa 150000 (N) ở mỗi cầu. Do vậy phương án thiết kế có thể đáp ứng được trong việc đánh giá hiệu quả phanh tại mỗi cầu xe cho hầu hết các ô tô thương mại đang lưu hành. Kết quả của bài báo là cơ sở lý thuyết quan trọng trong việc nghiên cứu thử nghiệm bệ thử phanh có chất tải trong tương lai.

Công tác lưu trữ hồ sơ tại các cơ quan, tổ chức có thẩm quyền là một vấn đề cần thiết trong việc quản lý và tổ chức bảo quản tài liệu. Tuy nhiên, hiện nay với số lượng hồ sơ lưu trữ ngày càng nhiều và có nhiều loại văn bản quy định lưu trữ khác nhau dẫn đến việc tình trạng quá tải tài liệu trong quá trình lưu trữ. Do đó, việc phân loại hồ sơ theo thời hạn bảo quản là một công đoạn rất quan trọng trong việc bảo quản, góp phần tối ưu hóa thành phần trong các phòng lưu trữ, tiết kiệm chi phí bảo quản tài liệu. Để góp phần giải quyết được vấn đề trên, trong bài báo này, chúng tôi trình bày nghiên cứu đánh giá sự hiệu quả của mô hình BERT so sánh với các thuật toán máy học truyền thống và mô hình học sâu trên các bộ dữ liệu thực tế hồ sơ lưu trữ theo thời hạn bảo quản ở các cơ quan. Kết quả nghiên cứu cho thấy rằng, mô hình BERT đạt kết quả tốt nhất với độ chính xác là 93,10%, độ phủ là 90,68% và độ đo F1 là 91,49%. Kết quả này cho thấy rằng, mô hình BERT có thể được áp dụng để xây dựng các hệ thống hỗ trợ phân loại hồ sơ theo thời hạn bảo quản là hoàn toàn khả thi.
