Stratigraphy of the Fiskenæsset anorthosite complex, southern West Greenland, and comparison with the Bushveld and Stillwater complexes
Authors: Myers J.S
Published: June 2021

The Fiskenæsset complex is a thin layered sheet of deformed and metamorphosed anorthosite, leucogabbro, gabbro, peridotite and dunite, with numerous chromitite layers and lenses. It occurs in an Archaean terrain of amphibolite and granulite facies gneisses as layers up to 500 m thick with outcrop lengths ofup to 25 km and as trains offragments ingneisses, in a belt 50 km wide and 100 km long in the Fiskenæsset region (fig. 28). The Fiskenæsset complexhas given an Rb/Sr whole rock age of 2810 ± 120 m.y. (Alexanderet al., 1973), and gneisses which cut it have given an Rb/Sr whole rock age of 2880 ± 50 m.y. (Moorbath &.. Pankhurst, in press) and a U/Pb zircon age of2835 ± IO m.y. (Pidgeonet al., 1976): A Pb/Pb whole rock age of 2810 ± 70 m. y. from both anorthosite and gneiss from Fiskenæsset has been interpreted as the age of metamorphism (Black et al., 1973).
Field work in central and northern East Greenland
Authors: Steenfelt A
Published: June 2021

The expedition to central and northern East Greenland in 1975 had 29 participants. Ten of these took part in the programme for uranium prospecting (Steenfelt, and Secher et al., this report) and 5 field teams studied the following subjects: the sedimentology of continental Trias in Scoresby. Land (Clemmensen & Andreasen, this report), the stratigraphy and structure of the lower Eleonore Bay Group sediments in the Alpefjord region (Caby, this report), the geochemistry of heavy metals in the Eleonore Bay Group, the Caledonian crystalline complex in relation to older crystalline rocks (Frederichsen & Higgins, this report), and finally the Quaternary deposits around CIavering Ø.
Reconnaissance work in the crystalline complexes of northern East Greenland between 72° and 74°N
Authors: Friderichsen J.D , Higgins A.K
Published: June 2021

Most crystalIine rocks of northern East Greenland have until recently been regarded as representing the deep-seated mobile core zone of the Caledonian orogenic belt (Haller, 1971). However, recent regional mapping and isotopic studies in the Scoresby Sund region indicate that the main development of the crystalline complexes relate to Archaean and Proterozoic orogenesis, with a relatively superficial Caledonian overprint (Henriksen & Higgins, 1976). It was a logical step to extend field studies northwards to the crystalIinerocks ofthe region between 72-74°N (fig. 32). These studies supplement isotopic work in progress on material from the crystaIline complexes collected by D. C. Rex (Leeds) in 1974 (Rex et· al., this report), as well as the research being carried out on various aspects ofthe Eleonore Bay Group by R. Caby (MontpeIIier) this report and H. Stendal (Copenhagen).
Uranium exploration in northern East Greenland

The uranium prospecting programme between 72° and 76°N which commenced in 1973 (Nielsen & Larsen, 1974: Nielsen & Steenfelt, 1975) was continued in 1975 from GGU's base at Stordal in Hudson Land. The programme included detailed geological and radiometric investigations in areas of high radioactivity as well as geochemical sampling.
Progress report on geochronological investigations in the crystalline complexes of the East Greenland Caledonian fold belt between 72° and 74°N
Authors: Rex D.C , Gledhill A.R , Higgins A.K
Published: June 2021

In the summer of 1974 two of the authors (D. C. R. & A. R. G.) collected samples from vanous crystalline units in the innerfjord region ofthe Caledonian fold belt between 72° and 74°N. with a view to testing current hypotheses of the geological history of the region. The only dates so far available from this region are a few K-Ar mineral ages reported by Haller & Kulp (1962) all of which reflect Caledonian orogenesis. In the Scoresby Sund region isotopic work on crystalline units comparable to some of those reported on here has yielded Archaean and middle Proterozoic as well as Caledonian ages (Hansen et al., 1973, 1974; Rex& Gledhill, 1974; Friderichsen & Higgins, this report).
High precision photogrammetric methods used in geological mapping
Authors: Dueholm K.S , Pedersen A.K , Ulff-Møller F
Published: June 2021

As part of a programme of experimental photogrammetric mapping we present results of geological mapping using advanced photogrammetric instruments in order to test the applicability of such sophisticated methods to geology. Two experiments are described. They were performed to test the methods on regional and detailed mapping respectively. In both cases vertical aerial photographs at an approximate scale of 1:50000 were used. Different types of photogrammetric instruments constructed for and normally employed in topographical mapping were used. For photograllllpetric principles and instruments see for instance Schwidefsky & Ackermann (1976).
Structural geology of central Peary Land, North Greenland
Authors: Pedersen S.A.S
Published: June 2021

The region investigated in 1978 between Jørgen Brønlund Fjord - Øvre Midsommersø in the south and Frederick E. Hyde Fjord in the north consists of c. 1½ km thiekness of Lower Palaeozoic carbonates overlain by an up to 1 km thick series of Silurian flysch (Christie & Peel, 1977). In general the region is part of the Palaeozoic platform that ean be divided into three major E-W trending physiographic belts: a southern belt where the carbonates form plateaus incised by steep valleys, a central belt consisting of characteristic conical mountains marked by concentric terraces of resistant sandstone beds in the flyseh (Dawes, 1976, fig. 249), and in the fold belt to the north the mountains rise up to altitudes of 1000-1500 m and are covered by extensive ice caps (fig. 17). The southern border of the region, the Øvre Midsommersø - Jørgen Brønlund Fjord area, was mapped by Jepsen (1971) while the Lower Palaeozoic stratigraphy in the central part af the region has been established by Christie & Peel (1977) at Børglum Elv. Some structural aspects af the gealogy at Frederick E. Hyde Fjord are briefly described by Dawes (1971) and Dawes & Soper (1973). Prior to the field work a comprehensive photogeological interpretation was carried out on vertical aerial photographs (seale c. 1:60000) and compiled on six uneontoured l: 100000 photomosaic maps. The 1978 field work and laboratory studies using a Kern PG 2 photogrammetric instrument form the first detailed study of the fold belt margin. For descriptive purposes the region investigated in 1978 has been subdivided into seven areas (fig. 17), the main struetural features of which form the basis of this report.
Seminar on Nagssugtoqidian geology - an introduction
Authors: Korstgård J.A
Published: June 2021

The geological Survey of Greenland (GGU) was established in 1946 and its activities were initially concentrated on a hitherto relatively neglected part of Greenland - the Precambrian terrains of the central and southem west coast. Field work started in 1946 with reconnaissance mapping of the country between latitudes 69°N and 63°45'N on the west coast of Greenland under the direction of A. Noe-Nygaard and H. Ramberg. A reconnaissance map on a scale of 1:500 000 covering all areas accessibie from the coast was published in 1961 (Noe-Nygaard & Ramberg, 1961) with a brief description. Soon after the mapping started it became possibie to divide the northem part of the Precambrian terrain into a southern, older fold belt and a northem, younger belt (the 'Nagssugtoqides') on the basis of the deformation and metamorphism of a pre-Nagssugtoqidian swarm of basic dykes - the Kangâmiut dykes. These early results were published in a now c1assic paper by Ramberg (1948).
The effects of solid and vapour phase compositional variations on the amphibolite facies to granulite facies transition in the Agto metadolerites
Authors: Glassley W.E , Sørensen K
Published: June 2021

Metadolerites occurring in the vicinity of Agto (within the Isortoq Complex of central West Greenland) have been metamorphosed in upper amphibolite to garnet granulite facies. Detailed sampling and petrographic study of these demonstrates that the entire sequence of assemblages may occur in individual dykes, with the amphibolite assemblages normally restricted to dyke margins, garnet granulite facies rocks occurring in the dyke cores, and pyroxene granulite facies rocks intervening between these two. Bulk rock chemical analyses demonstrate that the dykes are chernically homogeneous with respect to all oxides except Al2O3 and Na2O. Nevertheless, variation in the latter two oxides is small, and demonstrably is not a parameter which significantly controls assemblage development.
Isotopic re-equilibration of Rb-Sr whole rock systems during reworking of Archaean gneisses in the Nagssugtoqidian mobile belt, East Greenland
Authors: Pedersen S , Bridgwater D
Published: June 2021

Samples from small vertical shear zones cutting retrogressed granulites near the northem margin of the Nagssugtoqidian mobile belt give an Rb-Sr whole rock age of 2660 ± 180 m.y. (I.R. 0.7016) indistinguishable from that of their country rocks in spite of massive alkali metasomatism among the shears. Regional samples of garnet gneisses formed during partial remelting of Archaean quartzo-feldspathic gneisses and pelites during Proterozoic contact metamorphism yielded points which scatter about a 1950 m.y. reference isochron (I.R. 0.7054). The scatter shows that re-equilibration has not occurred on a scale of kilometres when the gneisses were partiaIly remelted. Samples from a single 10 x 20 m outcrop of highly deformed tonalitic gneiss with basic inclusions near the centre of the mobile belt yielded points which scatter about a 1875 m.y. reference isochron (I.R. 0.7039). Samples less than 500 g in weight yield points close to the reference isochron, while those from samples over 1000 g Iie above the 1875 m.y. isochron suggesting re-equilibration has been on a scale of 5-10 cm. Samples from a post-tectonic pluton emplaced near the centre of the mobile belt give a whole-rock age of 1583 ± 27 m.y. (I.R: 0.7035). Regional low Rb-Sr ratios in the country gneisses do not perrnit use of the initial ratio to distinguish mantle from a lower crost source.
Wanton disfiguration of famous Skaergaard outcrop deplored
Authors: Bridgwater D , Davies F.B , Gill R.C.O , Gorman B.E , Myers J.S , Taylor P
Published: June 2021

A classic outcrop of the Skaergaard intrusion, first described and made famous in the original description of this area of East Greenland by Wager & Deer (1939, pI. 11, figs 1 and 2) was visited in 1977 and found to have been senselessly vandalised. We consider this to be inexcusable. The Skaergaard intrusion is unequalIed in igneous petrology as an example of crystal fractionation and magmatic evolution, and has been the subject of extensive research since its discovery (see bibliography in the 1962 reprint of Wager & Deer, 1939; Wager & Brown, 1968).
Precambrian geology of the Upernavik - Red Head region (72°15'–75°15'N), northern West Greenland
Authors: Escher J.C , Stecher O
Published: June 2021

A geological reconnaissance of the region between 72°15' and 74°15'N was made by Escher & Pulvertaft (1968) during the summer of 1967. In 1977 the region was revisited by J. E. and O. S. and the geological survey was extended as far north as Steenstrup Gletscher (75°15'N) (fig. 7). Both investigations aimed at the production of a 1:500000 geological map sheet of the Mârmorilik - Red Head region. The GGU motor cutter K. J. V. Steenstrup with Andreas Vidstein as skipper provided logistic support for the summer's work. This part of Greenland's coast mainly consists of islands and peninsulas and is very suitable for field work from a boat. Winter ice normally disappears before July giving boats free access to most of the fjords. Stable weather conditions during the summer months, the generally gentle topographic relief of the region and the very good degree of rock exposure make the region ideal for field work.
Shallow core hole drilling and sampling for the investigation of organic matter rich shales in 1976, Nûgssuaq, central West Greenland
Authors: Schiener E.J , Leythaeuser D
Published: June 2021

As a continuation of the special investigations carried out in the Nûgssuaq embayment up to 1975 (Schiener, 1976), a joint field programme between GGU and the Petroleum & Organic Geochemistry Research Group (EOG) of the Nuclear Research Establishment (KFA) Jiilich, West Germany, was embarked upon in 1976. The programme was supported by a grant from the Danish Natural Science Research Council (SNF) and a contribution by KFA/EOG. It constitutes an essential part of a project within the SNF sponsored research in energy related topics (Organic Geochemistry, West Greenland). Overall coordination of the group was handled by E. J. S. who also carried out most of the surface sampling. A drilling party of four was led by D. L. Logistic support was provided by the GGU motor cutter K. J. V. Steenstrup with Andreas ViOstein as skipper and by an Agusta Bell Jet Ranger II, chartered from Greenlandair Charter A/S. The operations were conducted from the old GGU base at Marrait on Nugssuaq.
Investigation of Lower Palaeozoic rocks in northern East Greenland
Authors: Frykman P
Published: June 2021

Field work in 1977 was carried out primarily to collect rock samples for use in establishing a biozonation based on micro-fossils for the East Greenland Cambro-Ordovician sequence described by Cowie & Adams (1957). The most extensive sampling was done in the two type-sections of Cowie & Adams (1957) in Albert Heim Bjerge and Ella ø (fig. 35) in which macro-fossils are relatively sparse. In addition to this, an investigation was made of the virtuaIly unexplored C. H. Ostenfeld Nunatak in the Wordie Gletscher, from which Cowie & Adams (1957, p. 45) reported the presence of rocks belonging to the Hyolithus Creek Formation and the Cass Fjord Formation.
Potassium-argon ages from Phanerozoic basic dykes in South-East Greenland
Authors: Mitchell J.G
Published: June 2021

Nine basaltic dykes were sampled by coring during geological reconnaissance of the south-east coast of Greenland (Bridgwater et al., 1977) between Angmagssalik (65°40') and Nordfjord (fig. 49). The samples were initially collected for palaeomagnetic investigations (Beckmann,1977). In the field it was assumed that all the fresh basic dykes in the region were Tertiary in age and represented a southern continuation of the coastal dyke swarm described by Wager & Deer (1938). The timing of dyke injection is very important as a possibie indication of the initial break-up of the original North Atlantic mass. Furthermore, it was assumed that the major coast-parallel dyke swarm (for example site 26 & 28, see fig. 49) was the continuation of the more intense Tertiary dyke swarm reported by Wager & Deer (1938) further north, while the more sporadic dykes with other trends were presumed also to belong to the same general period of injection. The preliminary palaeomagnetic studies by Beckmann (1977) showed no consistent differences between dykes grouped according to their trends.
Silurian biostratigraphy: revision of the North Atlantic Realm in the Llandovery
Authors: Boucot A.J , Hurst J.M
Published: June 2021

Llandovery faunas have been considered more cosmopolitan than any others during the Lower Ordovician - Middle Devonian with only two undivided biogeographic Realms, the North Atlantic and Malvinokaffric, being recognised. Endemie pentameroids known from the Ashgill - Middle Llandovery of the Uralian region, Siberian Platform and adjacent Sette Daban occur commonly in North Greenland. Thus, during this time and in biofacies rich in pentameroids, the North Atlantic Realm appears divisible into a North Atlantic Region and a Uralian-Cordilleran Region, as in the Upper Silurian.

Seismic mapping of Lower Tertiary sediments offshore West Greenland between 64° and 68°N
Authors: Risum J.B
Published: June 2021

During 1977 and 1978 the first data obtained from commercial petroleum exploration of the West Greenland shelf were released (Henderson, 1978). The release consisted of geophysical data, mainly in the form of reflection seismic sections, and of a summary of information from the Kangamiut 1 well (Geological Survey of Greenland, 1978). This was drilled during 1976 to a total depth of 3874 metres, and allows the geophysical interpretations to be tied into a stratigraphicai framework.
Organic geochemical and microscopical study of sedimentary organic matter, central West Greenland
Authors: Perregaard J , Schiener E.J
Published: June 2021

Sample material from shallow core hole drilling (187 core samples) and outcrops (more than 200 surface samples) were collected on Disko, Nugssuaq and Svartenhuk Halvø during the summer of 1976 in a joint field programme between GGU and the Research Group for Organic Geochemistry of the Nuclear Research Establishment (KFA), Jülich, Federal Republic of Germany (Schiener & Leythaeuser, 1978a). The samples have been studied in the laboratory both by organic geochemistry and by reflected light microscopy. The main objectives were the appraisal of the folIowing parameters: (1) Richness in organic matter. (2) Maturation. (3) Type of organic matter.

Silurian carbonate mounds of south-east Peary Land, eastern North Greenland
Authors: Mabillard J.E
Published: June 2021

Thc carbonate mounds of Peary Land form part af a biohermal belt which can be traced east-west across North Greenland (Dawes. 197 J, 1976). Carbonate mounds in central Peary Land (fig. 27, locality 1) have been described by Mayr (1976), Christie & Peel (1977) and Lane & Thomas (1979). This paper discusses previously undescribed carbonate mounds from south-east Peary Land (fig. 27, localitics 2-11). In this region the widely spaced mounds form low hills and vary in size from tens af metres across to large biohermal complexcs covering several square kilometres.
A reconnaissance of the Quaternary geology of eastern North Greenland
Authors: Funder S , Hjort C
Published: June 2021

The aim of the field work in 1979 was to provide a stratigraphic framework which, together with later air-photo interpretation, will make possibIe the drawing of a 1:500 000 Quaternary map of the area. We concentrated our work on localizing and dating the outer limit of maximum ice cover, and on determining when glaciation started, and at what time the present distribution of ice was achieved. However, much work was also done on the pattern of isostatic readjustment and, in easternmost Peary Land, investigations were made on a c. 100 m thick sedimentary sequence of pre-Holocene age at Kap København. Figure 43 shows the area and place names mentioned in the text below.
Preliminary Rb-Sr isotope evidence on the age and metamorphic history of the North Greenland crystalline basement
Authors: Kalsbeek F , Jepsen H.F
Published: June 2021

No outcrops of crystalline basement rocks are known in the eastem part of North Greenland, mapped in 1978 and 1979 by the Geological Survey of Greenland. The oldest rocks are sandstones of the Proterozoic Independence Fjord Group (Collinson, this report). However, ice-transported boulders of gneisses, amphibolites and granitic rocks indicate the presence of crystalline rocks under the Inland Ice, perhaps not far south of the ice margin (fig. 46). The nearest outcrops of crystalline basement in North Greenland occur at the head of Victoria Fjord, c. 250 km west of Independence Fjord (Hurst & Peel, 1979). These rocks have as yet not been mapped or studied.

Провести оцінку клініч-ної та функціональної ефективності застосування навігаційних шаблонів та пацієнто-специфічних фік-саторів у пацієнтів з переломом голівки нижньої ще-лепи у порівнянні із традиційними методами остео-синтезу.Матеріалом даного дослідження було 37 пацієнтів з 48 переломами голівки нижньої щелепи (31 чоловік та 6 жінок, віком від 19 до 61 року, середній вік 38±11,8 років). Залежно від способу проведення остеосинтезу голівки нижньої щелепи всіх пацієнтів було розділено на 2 групи, однорідні за віком, статтю та важкістю травми.Хворих в обох групах було обстежено згідно станда-ртної схеми, що включала збір анамнезу, оцінку зага-льного та місцевого статусу, застосування лабора-торних і інструментальних методів дослідження.Використання навігаційних хірургічних шаблонів та пацієнто-специфічних фіксаторів у пацієнтів із пере-ломом голівки нижньої щелепи дозволяє покращити анатомічні і функціональні результати їх хірургічно-го лікування, а саме збільшити точність відновлення анатомічної форми голівки, зменшити частоту оклюзійних порушень та вторинних зміщень, а та-кож збільшити максимальну амплітуду рухів ниж-ньої щелепи на 6,4-20 %.
ОЦІНКА ВПЛИВУ ПРЕПАРАТІВ АУТОПЛАЗМИ НА АКТИВНІСТЬ ЕЛАСТАЗИ ТА ВМІСТ МАЛОНОВОГО ДІАЛЬДЕГІДУ В РОТОВІЙ РІДИНІ ХВОРИХ НА ГЕНЕРАЛІЗОВАНИЙ ПАРОДОНТИТ

Хронічний генералізований пародонти займає одне з провідних місць в структурі стоматологічної захво-рюваності. Традиційні методи лікування запальних захворювань пародонту не завжди достатньо ефек-тивні, про що свідчить хронічний перебіг і періодичні загострення процесу у більшості пацієнтів. На су-часному етапі інтерес представляє вплив компонен-тів аутоплазми на оптимізацію природної регенерації тканин пародонту, що сприяє підвищенню місцевого імунітету.Мета дослідження Вивчення динаміки біохімічних маркерів запалення тканин пародонта в ротовій рі-дині пацієнтів на генералізований пародонтит на тлі лікування з використанням препаратів аутоплазми.У групі пацієнтів із застосуванням АМК і i-PRF вияв-лено більш низький рівень активності еластази у від-далені терміни після проведеного лікування. У групі пацієнтів з використанням АМК через 2 роки він склав 0,80 ± 0,05 мккат / л, в групі i-PRF 1,20 ± 0,09 мккат / л, що достовірно відрізняється від показника в групі порівняння 1,71 ± 0,10 мккат / л. Мінімальний вміст МДА відзначено в групі хворих, які отримували АМК. Так само достовірні дані зниження вмісту МДА у віддалені терміни після лікування були отри-мані в групах з PRP 0,32 ± 0,02 ммоль / л і з i-PRF 0,32±0,02 ммоль / л у порівнянні з групою порівняння 0,40±0,03 ммоль / л (Р2 <0,05). У групі, яка в комплек-сі лікування отримувала РРР, відзначалася тільки тенденція до зниження рівня еластазноъ активності та вмісту МДА.Таким чином, отримані результати показали, що за-стосування препаратів аутоплазми призводило до зниження запалення в усіх досліджуваних групах. Препарати АМК і i-PRF володіють найбільш вира-женими протизапальними ефектами в ротовій по-рожнині.
Educación Tradicional: Un modelo de enseñanza centrado en el estudiante
Authors: Galván-Cardoso Ana Patricia , Siado-Ramos Elizabeth
Published: June 2021

El estudio tiene como propósito analizar la educación tradicional como un modelo de enseñanza centrado en el estudiante. Se sustentó en teorías referenciales de autores como Morin, (2011), Freire (2002), entre otros. Es una investigación de carácter descriptiva, bajo un diseño documental bibliográfico. Como conclusión, se cree necesario que los alumnos visualicen a la escuela como una parte significativa en su vida, para así comprender el significado de lo que están estudiando. Los niños/as de hoy en día son más conscientes del mundo que les rodea de lo que han sido las generaciones pasadas. Por ello, la escuela no se puede construir sobre cómo era antes, independientemente si ese modelo funcionaba o no, ya que era un una perspectiva diferente y los niños/as de generaciones anteriores respondían a patrones culturales y sociales que los que se viven actualmente

The COVID-19 crisis quickly led to the closure of educational institutions at all levels around the world, from one moment to another, millions of children and young people around the world were left without receiving their face-to-face classes, and many of them went through virtual classrooms framed in a phenomenon known as emergency remote teaching (ERT). This research sought to determine that well-designed and planned online learning experiences are significantly different from virtual courses offered online in response to this crisis, in order to identify what were the main areas of opportunity that learning in this emergency brought to teachers, students and educational institutions. A 12-item instrument was applied that was analyzed under a systematic random probability sampling, obtaining a sample of 49% of the population. The results made it possible to show the difficulties that arose, as well as the tools and platforms most used during the crisis in the institution of study in order to take advantage of knowledge to improve the learning experience of students.

Published: June 2021

The objective of the present quantitative study was to know the difference in the level of emotional intelligence of the university students to establish possible socialization strategies in emotional competencies. The participants, selected through a non-random sampling, were 40 students of the Higher University Technical level, 15 women and 25 men, with ages between 18 and 22 years. The Trait Meta Mood-Sacale self-report test (TMMS24) was applied. The data was analyzed with the statistical program Spss 24 and the Pearson correlation test. The results show that there is no correlation between gender and emotional intelligence, but in females there are adequate levels of attention and emotional clarity and low emotional regulation, while men have low levels of attention and emotional clarity but high levels in emotional repair; also globally, women present a greater level of emotional intelligence, in relation to men. It concludes that there is a need to have comprehensive training in the curriculum that encompasses academic knowledge and emotional competences, because the development of emotional intelligence in students helps to shape full human beings and valuable workers.

Published: June 2021

The abusive consumption of alcohol in university students constitutes one of the risk factors for their health, which can lead to problems in the academic, social and economic aspects. In the present work a study on the type of alcohol consumption in university students is shown, which aims to identify the risky and harmful consumption of alcohol in students of the UT del Norte de Aguascalientes, as well as carry out a comparison to determine if there were modifications in the type of consumption presented by the students of the 2018-2020 generation. For this study, the Alcohol Use Disorders Identification Test (AUDIT) was applied online in 925 second and fifth semester students in the educational programs of the Higher Technical level. The information collected was treated only statistically, using descriptive statistics for this purpose. Identifying the type of alcohol consumption in students will allow the UTNA to carry out activities that promote awareness of negative consequences, especially in the academic sphere, such as low academic performance, lag and / or dropout.

The story of post-industrial urban decline in America is well known. Bustling cities fall victim to changing economic structures and globalization. Wealth moves out of city centers, leaving behind evacuated buildings and vacant lots where houses once stood and transforming vibrant neighborhoods into sparsely populated areas that lack the density necessary to sustain urban life. Municipalities deem abandoned buildings “blight” and assemble task forces to eradicate them. In response to this pressing urban reality, we have been developing a speculative approach to reusing buildings and materials called “reassembly.” Reassembly views a building’s materiality as a matter-of-fact, as a resource for architecture stripped of the negative assumptions commonly associated with disused properties. Building components are taken apart, moved around, piled up, and mixed with new construction to create alternative uses and forms.
Politics of Space and its Shadows
Authors:   New York Institute of Technology, Kim Dongsei
Published: June 2021

This paper examines what the public, architects, urban designers, and city officials can learn about significant public spaces from emergent technologies and data generated from growing social media. Interrogating this analytical method aids us to recognize social media’s potentials, such as gaining a deeper understanding of the relationship between how public spaces are “represented” and how they are “physically experienced” through the means of technology. This investigation combines emerging image recognizing algorithms— Semantic Segmentation—with location-tagged images from Instagram to investigate the newly opened Seoullo 7017 walkway in Seoul. It argues that we should recognize these newly generated “big data” as a form of “collective intelligence” that can stimulate proactive engagement with our everyday interactions with public space. Equally, the findings of this investigation reveal to our society how to cautiously engage these “collective intelligence” with counterbalancing values.
Design Strategies for Safer and More Inclusive Public Spaces

Public space in the city is being continuously contested. The most compelling of these challenges comes from the recent terrorist attacks on cities across the world. While the awareness of the need to ‘design against terrorism’ and a demand for greater safety in public spaces has entered into citizen’s consciousness -given the perception of fear due to recent attacks- drastic security and surveillance measures usually go against a more open and inclusive public realm.
From Conventional Recycling to Creative Reuse: Empowering Local Industrial Resources Through Synergistic Practices
Authors:   Texas A&M University, Ali Ahmed K.
Published: June 2021

This paper seeks to introduce a novel approach in salvaging the urban realm through exploring ways in which design can extrapolate the use and the value of consistent industrial byproducts, mainly from the automobile industry. The research begins with a need to conserve materials and energy with a focus on adding value by design. In this paper, a speculative design work and comparative analysis have been conducted. The method begins with the analysis of automobile byproduct materials, observations of procurement of new material and analysis of proposed designs of automobile body manufacturing. The goal of the study is to transform the linear approach in making building components, in particular, building exterior metal skins and cladding systems, to a closed-loop approach, which ensures multi-dimensional economic, social, and environmental benefits. The study introduces a novel approach in initiating a symbiosis between non-hazardous automobile waste and the building and construction industry. In particular, creating building skin systems from by-product galvanized sheet metal from the automobile industry. The results are expected to change the focus of the current waste management practices in the manufacturing industry from conventional recycling to creative reuse.
Small Room / Big Window

The city of Munich currently faces great demographic pressure, as it is expected to add 200.000 new dwellings over the next decade while facing a sharp shortage of available land. With that problem in mind, this project proposes to re-densify the suburban neighborhoods of the city of Munich built between the 1960s and 70s, taking advantage of the sparseness with which they were originally laid out. The project focuses on the areas of Neuperlach and Taufkirchen, and proposes to understand them as an unfinished landscape, the product of unresolved tensions between different planning approaches at the time of their realization. It then proposes to re-interpret the existing fabric and to transform it into a more urban and complete whole by replicating existing typologies in order to create denser compositions and to reinforce the perimeter of each city block.
Yielding Actions

In 1992 Gabriel Orozco, the Mexican artist based in New York, conceived the idea of his work Yielding Stone. The experience consisted in the construction of a plasticine sphere, of approximately the same weight as the artist, which was rolled through the streets of a city. The photograph used to present it summarizes the action and the concept: the soft and imperfect ball appears on a sewage grid, the corrugated marks of these bars have been imprinted on the surface. Later, in different trips, the sculpture has rolled through the streets of each city where it has been exposed, changing its shape slightly, trapping textually layers of urban waste, preserving the trace of its route, reverse trail of the trail in the streets.
Thick Roofs: Technological Containment and Symbolic Form
Authors:   Rice University, Chang Michelle
Published: June 2021

The roof is one of architecture’s primary constituent elements. Whether its origins stem from functional, moral, or political purposes in uncertain, but the design of roofs has historically engaged form with performance. In Laugier’s account of the primitive hut, the roof was created to shield humans from nature; Semper contends that it came about to protect the hearth; and Koolhaas suggests that, from the beginning, roofs were made to signify power.1 Though these origin stories leave out the complex relationships between cultural, economic, and technical contexts, their reductive clarity serves as a lens for judging architectural qualities of scale, shape, and proportion.

Smart grid is the most significant topic in power system due to numerous benefits. Smart grid is the integration of distributed generation. DG plays an important role in different configurations either in grid connected mode or islanded mode. Multiple configurations will result in fault currents this may lead to damage to the existing protective devices. In this paper Fuzzy is used to optimally locate DG and Jaya a new optimization technique is adapted to size the Fault current limiter. Controlled Impedance Fault Current Limiter (CI-FCL) is used to reduce the magnitude of fault current and also avoid false tripping of protective devices. A program is developed in MATLAB 2017Ra to test the IEEE 33 and 69 bus distribution systems the results are compared with the analytical PSO method. The results shows the effectiveness of Jaya Algorithm and also reduces the computational time and no. of iterations.
