HGPT2: An ERA5-Based Global Model to Estimate Relative Humidity
Authors: Mateus Pedro , Mendes Virgílio B. , Plecha Sandra M.
Published: June 2021

The neutral atmospheric delay is one of the major error sources in Space Geodesy techniques such as Global Navigation Satellite Systems (GNSS), and its modeling for high accuracy applications can be challenging. Improving the modeling of the atmospheric delays (hydrostatic and non-hydrostatic) also leads to a more accurate and precise precipitable water vapor estimation (PWV), mostly in real-time applications, where models play an important role, since numerical weather prediction models cannot be used for real-time processing or forecasting. This study developed an improved version of the Hourly Global Pressure and Temperature (HGPT) model, the HGPT2. It is based on 20 years of ERA5 reanalysis data at full spatial (0.25° × 0.25°) and temporal resolution (1-h). Apart from surface air temperature, surface pressure, zenith hydrostatic delay, and weighted mean temperature, the updated model also provides information regarding the relative humidity, zenith non-hydrostatic delay, and precipitable water vapor. The HGPT2 is based on the time-segmentation concept and uses the annual, semi-annual, and quarterly periodicities to calculate the relative humidity anywhere on the Earth’s surface. Data from 282 moisture sensors located close to GNSS stations during 1 year (2020) were used to assess the model coefficients. The HGPT2 meteorological parameters were used to process 35 GNSS sites belonging to the International GNSS Service (IGS) using the GAMIT/GLOBK software package. Results show a decreased root-mean-square error (RMSE) and bias values relative to the most used zenith delay models, with a significant impact on the height component. The HGPT2 was developed to be applied in the most diverse areas that can significantly benefit from an ERA5 full-resolution model.

Published: June 2021

This study explores the effects of interactions among key stakeholders, i.e., auditors, underwriters, and firm owners on IPOs’ first-day returns in selected OECD nations. It also examines the alteration effects of legal origin (Common law and Civil law) on the relationship between the interacted key stakeholders and IPOs’ first-day returns. A total of four thousand one hundred and sixty-four IPOs from twenty-eight OECD nations are included in this study. Since it is cross-sectional data, a two-stage least square regression is applied. The empirical outcomes indicate that, in general, the interacted reputable underwriters and auditors have a positive impact on IPOs’ first-day return. The relationship is modified between common law and civil law nations, whereby in civil law nations, no significance is demonstrated except for the interaction between the reputable auditors and underwriters. In the common law nation, interactions between reputable auditors and ownership retention have an impact on IPOs’ first-day return. The research findings provide outlooks into an IPO framework for issuers, investors, and regulators. Issuers may want to weigh carefully the costs and benefits of hiring credible auditors and underwriters when going public as they act as signaling agents. As for the investors, they should take into consideration the involvement of reputable underwriters and auditors and the degree to which the IPO firms retain ownership, as the interactive effects give clear signals on firm valuation and IPOs’ first-day returns. Regulators may find the findings informative concerning the creation of a more organized regulatory and financial system that could lead to a deeper and more open financial market.
The Study of AR-Based Learning for Natural Science Inquiry Activities in Taiwan’s Elementary School from the Perspective of Sustainable Development
Authors: Lo Jung-Hua , Lai Yu-Fan , Hsu Tzu-Lun
Published: June 2021

Experiential activities are the most direct form of ecological teaching, so outdoor education is an important way of learning. Through direct observation and life experience, students will learn about the ecological environment, understand the importance of the ecological environment, raise their awareness of environmental protection, and put into practice the protection of the ecological environment. This study involved plant teaching activities that incorporated school plant learning paths into environmental education, so that students could learn about flora, experience nature, and take care of the environment. We created an augmented reality application for use in schools that takes the user on an ecological tour of the plants in the diet of butterflies. The application formed the localized and special mobile learning content in a school. Students were allowed to walk out of the classroom and use their mobile device to engage in autonomous learning, and we then determined their acceptance of the augmented reality application. Through this application we were able to tell whether students were able to adapt to learning with technology combined with traditional teaching methods. This application was tested on a group of elementary school students, who were then interviewed using quantitative and qualitative research methods to understand the users’ feedback.
The Spatial Correlation between Foreign Direct Investment and Air Quality in China and the Potential Channel
Authors: Xu Xindi , Wang Xinjun
Published: June 2021

Due to the attention given to air pollution, the impact of foreign direct investment (FDI) on air quality has led to many discussions on this topic; however, there is a lack of literature discussing the correlation between FDI and air quality from a spatial perspective. In China, the discontinuity of ground monitoring data further limits research in this area. Using a new air pollution dataset, this paper constructs a dynamic panel of 259 prefecture-level Chinese cities over the period 2013–2018 and reveals that FDI on average induces the pollution halo effect in host cities but shows direct correlation with air pollution in the outer conurbation areas. Further examination supports the main findings by showing that FDI presents the same correlation with coal consumption and thermal power generation of the local and the outer conurbation areas. The heterogeneity analysis finds that the industrialization stage, ecological construction, and technology development are important moderators for FDI’s pollution effect. The findings of this paper generate potential policy implications for regional green development regarding FDI.

Published: June 2021

Conventional energy resources are not climate sustainable. Currently, engineers and scientists are looking for sustainable energy solutions influenced by climate change. A wide variety of sustainable natural energy resources are available, but they require technical solutions for their implementation. The general trend in energy research is based on renewable resources, amongst which solar energy stands out, being the most mature and widely accepted. In this paper, the current state of the sustainable energy system has been analysed. The main purpose is to provide additional context to assess future scenarios. The study of past contributions allows sustainability planning and increasing the welfare of future society. The aim is to highlight global trends in research on sustainable solar energy from 1995 to 2020 through a bibliometric analysis of 4260 publications. According to their linkages, the analysed articles are distributed in nine clusters: Sustainability assessment, Sustainable energy solutions, Environmental payback time analysis, Sustainability of solar energy in different scenarios, Environmental sustainability, Solar energy applications, Sustainable energy optimisation, Energy transition and Energy and sustainable scenarios. The most repeated keywords are Sustainability, Renewable energy, and Solar energy. Energy research and the exploration of new renewable solar resources are still necessary to meet sustainable energy’s future challenges.

Authors: Bernat Katarzyna , Kulikowska Dorota , Zielińska Magdalena , Zaborowska Magdalena , Wojnowska-Baryła Irena , Łapińska Magdalena
Published: June 2021

Although anaerobic digestion (AD) enables biogas production and facilitates renewable electricity production, its effluent must be post-treated before discarding it into the environment. However, during AD designing, the post-treatment step is often overlooked. This paper presents the kinetics and efficiency of nitrogen removal from effluent after AD of leachate from the aerobic stabilization of the organic fraction of municipal solid waste. A two-stage SBR system was used. An ammonium oxidation rate of 15.5 mg N-NH4/(L·h) ensured a 98% nitrification efficiency (I stage). For denitrification (II stage), alternative carbon sources (ACS) (molasses, crude glycerine, or distillery stillage) were used. Two volumetric exchange rates (n) were tested: 0.35 1/d (COD/N-NO3 ratio of 8) and 0.5 1/d (COD/N-NO3 of 7). With all ACS and COD/N-NO3 ratios, almost 100% of nitrate was denitrified; at the COD/N-NO3 of 8, biodegradable organics remained in the effluents. At the COD/N-NO3 of 7, the denitrification removal rates were lower (29.6-45.1 mg N-NOx/(L·h)) than at the ratio of 8 (72.1–159.5 mg N-NOx/(L·h)), because of temporal nitrite accumulation. The highest nitrate removal rates were obtained with molasses, the lowest with a distillery stillage. Considering the nitrate removal rate and the effluent COD concentration, molasses was recommended as the most effective carbon source for AD effluent treatment at the COD/N-NO3 of 7.
Social Representations about Cultural Tourism in the Time of COVID-19: A Case Study of Langhe, Monferrato and Roero (Italy)
Authors: Rech Giovanna , Migliorati Lorenzo
Published: June 2021

Cultural tourism is recognised as one of the broader sectors of the tourism industry, embracing an extensive range of tourist interests. Italy is a remarkable tourist destination due to its cultural appeal in tangible and intangible heritage as well as its cultural resources connected to food and gastronomy, and it is of special interest since the COVID-19 pandemic was declared in March 2020. This study sought to analyse the perceptions of diverse significant actors regarding culture and tourism during the COVID-19 pandemic in Langhe, Monferrato and Roero, an area of southern Piedmont in north-western Italy. As part of a larger collaborative international project addressing the coronavirus situation, the research examined residents, tourists and tourism-related professionals to investigate their perceptions of culture and tourism. Data were collected through a survey employing three distinct questionnaires for the three target groups of residents, tourists and entrepreneurs and cultural bodies. The data analysis reveals that residents embraced a static representation of the local cultural tourism’s appeal and heritage, while tourists were motivated mainly by gastronomic and wine experiences. The perception of the coronavirus among the three groups of interviewees reflects a general reduction in almost all cultural activities and travel possibilities.
A Heuristic Method for Bus Rapid Transit Planning Based on the Maximum Trip Service
Authors: Wang Zhong , Lan Fengmin , Lin Zijing , Lian Lian
Published: June 2021

Bus rapid transit (BRT) is characterized by higher speed, higher comfort level, and larger capacity than conventional bus service. Although many cities worldwide have adopted BRT in recent years, there is an absence of scientific and quantitative approach for BRT network planning. The problem of BRT planning in an existing transportation network is very complex with constraints of road geometrics, regulations, right of way, travel demand, vehicle operations, and so on. This paper focuses on developing an optimization model for BRT network planning, where an integer programing model is established to identify station locations and route layout with the objective of maximizing the number of trips served by the network, subjected to constraints including distance between stations, cost of construction, road geometrics, etc. The detour factor of the BRT route, which is an important indicator but widely ignored in previous studies, is also taken as a constraint. A heuristic method is applied to generate optimal solutions to the integer programming model, followed by a case study using the transportation network and travel demand data in Luoyang, China. The numerical results show that the method is valid and can therefore be applied to improve BRT network planning and the sustainable transportation system development.
Experimental Dynamic Rigidity of an Elastic Coupling with Bolts
Authors: Ghitescu Marilena , Ghitescu Ion-Marius , Vlase Sorin , Borza Paul Nicolae
Published: June 2021

The paper presents an elastic coupling with bolts and intermediary non-metallic elements, which allows for radial and axial deviation and can absorb shocks and torsional vibrations. The designed bolts have a particular shape of a circular area of a length equal to the width of the non-metallic element, a cylindrical area larger than the diameter of the cylindrical groove where the non-metallic elements are mounted, and a cylindrical area smaller than the threaded area to avoid stress concentrators and bolt breakage. The coupling represents a symmetrical piece, having two planes of symmetry. Therefore, the study of such a mechanical system can be considerably simplified considering the design and description of the repeating elements. The novelty of this coupling consists in the existence of an intermediate disc between two half-couplings (driving and driven half-coupling). The non-metallic elements with different shapes are made of different types of rubber, mounted on cylindrical bolts fixed by the driving half-coupling, transmitting the motion in both directions.
Distribution, Drivers, and Threats of Aluminum in Groundwater in Nova Scotia, Canada
Authors: Hart Kristin A. , Kennedy Gavin W. , Sterling Shannon M.
Published: June 2021

Increased rates of acid deposition derived from the burning of fossil fuels over the last century have resulted in the acidification and increase in aluminum (Al) levels in freshwaters and soils in sensitive areas. While the acidification of surface waters such as lakes and rivers has been extensively studied, the acidification status and resulting Al concentrations in groundwater are poorly understood. Here we aim to describe the distribution of Al in groundwater across the province of Nova Scotia, Canada. We investigate the hydrogeological conditions that influence Al concentrations in groundwater and compare Al concentrations to legislated threshold levels for human and aquatic health. We found groundwater Al concentrations to be highest in areas underlain by plutonic and metamorphic bedrock types as well as surficial aquifers, with pH and organic carbon concentrations having the strongest correlation with groundwater Al concentrations. Few samples exceed the maximum acceptable concentration of 2900 µg/L released by Health Canada (2021), but these exceedances are important to highlight given the challenges with respect to Al treatment in private domestic wells and our evolving understanding of Al impacts to human health. High concentrations of Al in groundwater may also be exported to surface waters such as rivers and lakes, where they can be harmful to aquatic populations such as Atlantic salmon (Salmo salar). We recommend that private well owners test their water supplies for Al, and that further studies on Al export from groundwater to surface water be carried out in the most high-risk areas coincident with important Atlantic salmon river watersheds.

Published: June 2021

The water inrush of the Shangjiawan karst tunnel is used to study the evolution pattern of precursor water inrush information in water-filled caves and to further reveal the matching mode of the information. The three-dimensional numerical method FLAC3D was used to simulate the evolution process of water inrush after damage to a water-blocking rock mass structure in a water-filled cave and to obtain the evolution pattern of precursor water-inrush information caused by the damage. The results show that the multifield response to the characteristic precursor information of the water-inrush pattern after the fracture of the water-blocking rock mass follows the order of stress-field displacement-field seepage-field. Further, the matching pattern of the information shows that the stress field increased first and then decreased, the displacement field always increased, and the seepage field increased first and then decreased.
Borders and the Design of the Civic
Authors: Neuman Michael
Published: June 2021

The word border may be the most constraining on human thought and action in history. Whether borders on territory, borders from ideologies, from politics, or anything else; they all condition action and thinking. I want to focus on the many borders that humans erect, walls that we construct, and how they block flows and processes that constitute life and well-being. If this were a conference on sustainability or ecology, I would go on about how human borders, especially administrative and infrastructural ones, block ecological flows and processes and thus harm biological life, including humans. Most ancient traditions of wellness and health, including Ayurvedic, Tantric, Chinese, Greek, and Persian, stressed the free flow of energy. Blockage of flows in the body were sources of illness and disease. Borders of all kinds are infused into virtually every thing that humans create, from organizations and institutions to customs and traditions. Yet the most constraining borders of all are the borders on our own thinking. After addressing several essential characteristics of borders, a number of policies and actions are suggested for dealing with political conflicts and humanitarian crises related to borders.

Published: June 2021

Other features of the modern Russian rural society include the weakening of the position of agriculture itself, the increasing diversity of rural employment, the formation of rural-urban labor markets, all of which are directly related to the saturation of rural areas with urban residents, which gives impetus to the use of innovative forms of investment activity in the social sphere of emerging rural agglomerations. At the same time, the tasks set in the new State Program "Integrated Development of Rural Territories" (the beginning of implementation of which falls on January 2020) are not large-scale both to the existing networks of rural social services, and to the system of rural settlement and the nature of demographic processes in rural areas of Russia. There is an institutional imbalance, in which the management of the infrastructural development of the rural sociosphere is extremely difficult, and requires the introduction of new mechanisms, including related. The purpose of the study is to summarize the domestic and foreign experience of creating multifunctional public centers in rural areas, as well as to identify the possibility of realizing their investment potential. It is shown that the functioning of multifunctional public centers is an effective method for improving the quality of life of the rural population in the socio-cultural, socioeducational, social and leisure, social and household, tourist and educational spheres. The generalization of foreign experience allows us to distinguish centers by their functions (on the basis of educational institutions, cultural institutions, leisure centers); by spatial solution (in one building or several buildings); by location in a settlement (in the center of a settlement, near a transport hub, in an inter-settlement equidistant space). The domestic experience of providing multidisciplinary services to the rural population is primarily associated with two integrated approaches, when the resource-based approach.

Greater Mekong subregion should become a green farm in Asia: prerequisites, plans, implementation
Authors: Burova Elena Sergeevna
Published: June 2021

The agriculture remains a strategic sector of the economy, despite the widespread decline in its share in GDP production and employment. Its development is observed as a key factor in maintaining food security, as well as reducing poverty. That is why various farming methods are subject of particular interest, including organic production, which can maintain the ecological balance, preserve and increase the productivity of the main and most valuable resource of this sector — land, thus providing a longterm sustainable model of agricultural development. In addition, organic products are in great demand in the world market, which certainly makes impressive prospects for export development. "Green products" have a higher value added, which contributes to labor productivity increase and enhance the profi ts of farms. As a result, the development of organic production is a direct path to increase exports in monetary terms and to raise the living standards of the rural population, which is especially important in the GMS countries.The article highlights the advantages of organic farming, considers the stages of the emergence of "green agriculture", shows its dynamics in the GMS countries, the sectoral structure, and their export potential in the world and the region. The author concludes that GMS countries have great potential to become a major supplier of safe and environmentally friendly agricultural products, having already earned trust in premium markets and built up a reputation. However, despite all the advantages described and the gradual increase in the number of lands transferred to organic "rails", the current share of organic farms in the total lands does not exceed 0.5 %. In addition, the development of organic production is faced with a number of problems and contradictions. The key factor restraining the transition to "green production" is the duration of its conversion, causing the risks of farms falling into the "poverty trap".
Hygroscopicity of 1:2 Choline Chloride:Ethylene Glycol Deep Eutectic Solvent: A Hindrance to its Electroplating Industry Adoption
Authors: Brusas John Raymund , Dela Pena Eden May B.
Published: June 2021

Deep eutectic solvents have been established as feasible metal electroplating solvent alternatives over traditional toxic aqueous plating baths. However, water, either added intentionally or unintentionally, can significantly influence the solvent’s physical properties and performance, thereby hindering its industry application. In this study, the hygroscopicity, or the ability to absorb moisture from the environment, of synthesized ethaline (1:2 choline chloride:ethylene glycol) was investigated. The kinematic viscosity, electrical conductivity, electrochemical window, and water content of ethaline were monitored over a 2-week period. Karl Fischer titration tests showed that ethaline exposed to the atmosphere displayed significant hygroscopicity compared to its unexposed counterpart. 1H NMR spectroscopy revealed that water vapor was readily absorbed at the surface due to the hydrophilic groups present in the ethaline molecule. Water uptake resulted in the decrease in viscosity, increase in electrical conductivity and narrowing of the electrochemical window of ethaline. Solution heating at 100°C removed the absorbed moisture and allowed the recovery of the solvent’s initial properties.
Paul Ricoeur y la búsqueda del reconocimiento

Published: June 2021

El siguiente texto procura recorrer de manera sucinta el camino filosófico transitado por el pensador francés Paul Ricoeur en su búsqueda de significación para el concepto de reconocimiento. Se abordará el aporte de Ricoeur bajo la siguiente pregunta problema: ¿cómo superar el vacío del término reconocimiento en el ámbito filosófico? Para ello, se presentarán tres momentos: la identidad como transfondo, el desarrollo de la idea y su final significación filosófico-política. Este camino se constituye en una propuesta alternativa que pretende superar el vacío en el que ha caído dicho término a lo largo de la historia de las ideas, abriéndole la puerta al desarrollo de una teoría filosófica del reconocimiento con estatus independiente.

Published: June 2021

El objetivo fundamental del presente artículo es la configuración de una constelación de ficciones delirantes en la literatura latinoamericana contemporánea, a partir de la conceptualización del delirio literario y el análisis del proceso de construcción del relato delirante. Dado que, algunos narradores latinoamericanos despliegan ficciones delirantes en nuestros días, y existe un amplio número de casos, en donde el delirio se evidencia en la literatura de nuestro continente, autores como: Mario Bellatin, Roberto Bolaño, Rita Indiana Hernández, Horacio Castellanos Moya, Cristina Rivera Garza, entre otros. Por consiguiente, se centrará la atención en la creación de una base crítica para la interpretación del delirio de algunos personajes de la literatura latinoamericana contemporánea, como un constructo cultural que transgrede el orden social, y es asumido como resistencia y articulación de una praxis creativa.
El cultivo de las emociones
Authors: Ospina Nini Johana
Published: June 2021

Vastas son las interacciones, vínculos y tensiones entre la filosofía y la literatura, las cuales han estado determinadas en diferentes épocas y momentos históricos por la inclusión y la exclusión recíprocas. Dicha reflexión es planteada, entre otros, por la filósofa norteamericana Martha Nussbaum en El conocimiento del amor. Ensayos sobre filosofía y literatura(1992), por los filósofos franceses Gilles Deleuze y Felix Guattari en ¿Qué es la filosofía? (2003), y por Alain Badiou, en Justicia, filosofía y literatura (2007). Desde la perspectiva de estos autores, examinaré algunos antecedentes y circunstancias que han incidido en la relación entre filosofía y literatura, partiendo de la exploración de los elementos que identifican y diferencian a cada una, mostrando que la tensión existente entre ellas va más allá de la expresión de los opuestos lógica e imaginación, conceptos y sensaciones, emociones y racionalidad; y que la separación y contradicción entre éstas, se puede superar con la comprensión de su forma y contenido, con la proximidad a las perspectivas de observación y juzgamiento y con la consideración del cultivo de las emociones como posibilidad de lectura crítica sobre el mundo. De esta manera, resaltaré el papel de la literatura en la construcción de pensamiento, el carácter ético de la imaginación literaria como proyección en el otro, y la pertinencia de un ambiente de respeto entre las distintas áreas del conocimiento.

Published: June 2021

The article is devoted to the disclosure of theoretical and methodological foundations and development of practical recommendations for strategic tourism management in Ukraine. The main components of an effective strategy in the field of tourism are identified as well as the main levels of tourism development and appropriate tools for implementing this development. The authors have analysed the process of strategic decision making by enterprises in the field of tourism in a competitive environment. The strategies of tourism enterprises should be the basic provisions creating a hierarchical system with intertwined elements. This system should be in line with the national strategy for the development of tourism in Ukraine, combining macro-, meso-, and micro-levels. The ratified Programme of the sphere of tourism development of Volyn region exemplifies the practice of development and realisation programme and strategy by local authorities in the field of tourism. It has been concluded that coordination and control over the implementation of the Programme remain unsettled. Apart from the development measures and sources of funding the strategies for tourism development in the regions of Ukraine should also provide appropriate mechanisms for control, monitoring and reporting. The study of tourism has shown that this industry is currently experiencing at the stage of development, which is due to the long process of reforming Ukraine's economy. In this connection, the author has proposed the following measures aimed at withdrawing the tourism sector out of development: achieving European and world parameters of the balance of service quality and prices for these services; development of market mechanisms in the field of tourism; development of tourism in a mixed form of ownership; raising funds from the tourist structures independently, as well as bank loans and investments; development of an investments protecting mechanism, including the foreign ones; creation of a favourable tax policy to support tourism development, intensification of environmental activities to create normal living conditions and environmental safety of the territory; creation of programmes and further prognosticating the sphere of tourism development.
New mapping on Svartenhuk peninsula
Authors: Pulvertaft T.C.R , Clarke D.B
Published: June 2021

Svartenhuk, although petrographically the best known of the West Greenland basalt areas, was until now the least satisfactonly mapped. The accounts of Rosenkrantz et al. (1942) and Noe-Nygaard (1942) were written before either accurate topographical maps or aerial photographs of the area were available and thus the accompanymg geological maps are of a very generalised nature. Therefore, in order that the area could be satisfactorily represented on the Survey 1:500 000 sheets, it was necessary to remap it on new photogrammetric topographical maps, making full use of aerial photographs. This was our first task.

Precambrian fossils from the Ketilidian of South-West Greenland
Authors: Pedersen K.R
Published: June 2021

Ketilidian low-metamorphic rocks ca. 1700-2000 m.y. old are exceptionally well preserved in the Grænseland-Midternæs area north-east of Ivigtut, South-West Greenland. During the mapping of these rocks structures of possible organic origin were found. A further examination of these structures together with the examination of rock samples from the whole series has shown that both macroscopic and microscopic organic structures are present. The best preserved type is a complex globular structure of about 1/2 mm in diameter (Vallenia erlingi Raunsgaard Pedersen), but most of the organic remnants are microscopic globules and fragments with cellular structures. A description of some of the structures is in press (Bondesen, Raunsgaard Pedersen and Jørgensen, in press). The organic remnants and the sediments of Grænseland are so well preserved that it has been possible to extract small amounts of distinctive organic compounds.
Ultrabasic intrusives from Narssaq and Tugtutôq
Authors: Upton B.G.J
Published: June 2021

On the Panernaq peninsula [now named Ungussivik] north of Narssaq, five small outcrops of ultrabasic rock occur, the largest being some 200 m across. Conceivably these are connected at depth and should be regarded as probably comprising a single intrusion. The smallest (southernmost) of the outcrops is now, unfortunately, obscured by a Narssaq municipal refuse-tip. Two small bodies of similar ultrabasic material have been found on the eastern part of Tugtutôq island. All these ultrabasic masses are associated with the large olivine gabbro intrusions (Upton, 1964) and are held to represent younger intrusions into, or adjacent to, the latter. They are themselves cut by the big feldspar dykes and by the trachyte and comendite dykes of the regional WSW-ENE swarms.

Published: June 2021

The area between Angmagssalik fjord (ca. 66°N) and Køge Bugt (65°N) shown in fig. 3 was mapped by the writers during a two month field season in the summer of 1967. The Precambrian rocks of the area consist dominantly of biotite-hornblende or biotite-chlodte-epidote feldspathic gneisses (the grey gneisses of Wager, 1934). In these are intercalated pelitic, semipelitic and calcareous migmatitic gneisses with amphibolite facies mineral assemblages. The gneisses contain large numbers of concordant, semi-concordant and discordant bodies of metamorphosed basic and ultrabasic igneous rocks. Some of these are found interlayered with the metasediments.

A reconnaissance K/Ar dating programme on rocks from western Greenland has been carried out with an Ar-extraction apparatus set up at Fysisk Laboratorium II, H. C. Ørsted Institut. The mass spectrometric Ar determinations were carried out in the same labaratory by the second author. With the completion of this reconnaissance programme the extraction apparatus was moved to the Mineralogical-Geological Institute of the University of Copenhagen. Major changes are being made in connection with the re-establishment of the dating laboratory, and dating will not be resumed before the spring of 1968.
Field work supplementing photogeological interpretation of Nûgssuaq
Authors: Henderson G
Published: June 2021

In early 1967 the writer was given the task of undertaking a photointerpretation of the areas that make up the 1:100 000 geological map sheets 70 V. 1 N Agatdal and 70 V.1 S Qutdligssat. The object of the photointerpretation was to see whether, with the additional structural and lithological information obtainable from the aerial photos, it would be possible to complete the geological maps at this scale using the existing 1:50 000 geological held maps. These field maps were compiled on the basis of field work carried out over the years by expeditions to this part of Greenland led by Professor A. Rosenkrantz, University of Copenhagen.
The sandstones of the Precambrian Eriksfjord Formation in South Greenland
Authors: Poulsen V
Published: June 2021

The Precambrian continental sandstones in the Julianehåb district, South Greenland, are discussed with regard to distribution, lithology, structures, and origin. The sandstone/volcanics sequence, which was included as part of the Gardar formation by Wegmann (1938), is established as a separate formation - The Eriksfjord Formation. The formation is divided into six members, and a tentative correlation between the now separate sandstone areas is presented.

Authors: Watt W.S
Published: June 2021

A compilation is presented of all available rock analyses (138) from the alkaline Gardar igneous province of South Greenland with the exception of those from the peralkaline Illmaussaq intrusion. The analyses are accompanied by a brief description of the geological setting of the province and the major units within it. Variation diagrams are included to show trends and affinities in the province and are accompanied by similar diagrams from other alkaline provinces. A planimetric study shows that syenite is dominant in the province.
Origin of a deep buried valley system in Pleistocene deposits of the eastern central North Sea
Authors: Salomonsen Inger
Published: June 2021

In the North Sea, the sedimentary development of the late Tertiary and early Quaternary was dominated by deltaic sedimentation in a fast subsiding basin. During the Pleistocene, pronounced climatic changes affected the sedimentation of the area and progradation of the delta systems ceased. The Middle and Upper Pleistocene sedimentary successions consist of alternations of marine and fluvial deposits, partly reworked during glacial periods. Seismic records from the Danish sector of the North Sea reveal numerous deep incisions cut down from various levels of the Middle and Upper Pleistocene successions. These incisions are concluded to form a pattern of buried valleys. Detailed seismic stratigraphic analysis shows the occurrence of various internal unconformities within these buried valleys. It is concluded that the valleys originate from a river system developed in periods of repeated sea-level changes. Pluvial erosion during glacial sea-level lowstand and glacial meltwater action is proposed to have been responsible for the origin of the valley system. Thus, in Middle and Upper Pleistocene glacial periods drainage and associated sediment transport occurred from Northwest and Central European land areas via a presently buried river system in the southeastern North Sea towards a depositional basin north and northwest of the Danish North Sea sector.
Interactive computer processing and interpretation of pumping test data. A Micro-computer program using dynamic graphics
Authors: Madsen Bjarne
Published: June 2021

This paper presents a computer program for analysing pumping test data. The program is interactive and may be used with a minimum knowledge of computers. It can be applied to a wide range of transient problem types, from one dimensional groundwater flow to flow in anisotropic aquifers, horizontally as well as vertically. Various forms of type curves based on analytical solutions to the groundwater flow equation are available for the interpretation. The paper includes a listing of the entire computer program containing a total of about 1. 800 lines. The programming language is a BASIC-version suited for the Tektronix 4054, a graphic screen with a refresh option. This option allows the user to perform type curve matching directly on the screen by moving the chosen type curve to the position where it gives the best fit, in a manner similar to traditional manual chart interpretation. Plots of the measured data may be conveniently reproduced in semilog and log-log diagrams, either on the screen or as a hard copy printed by a plotter. The present version of the program makes use of tape cartridges, both for storing program and data files.

Published: June 2021

Baryonik rezonanslar üç kuarktan oluşan uyarılmış durumlardır. Kütle, rezonans genişliği ve ürün bolluğu gibi karakteristik özellikleri ortam tarafından etkilenebilir, böylece bu parçacıkların ölçümleri ile rölativistik ağır iyon çarpışmaları sonucu oluşan sistemin dinamiği araştırılabilir. Çok kısa ortalama ömre(τ ~ 10-23s) sahip olan baryonik rezonanslar, yüksek enerjili çarpışmalarda oluşan ortamın kimyasal donma noktası ile kinetik donma noktası arasında (i) bozunabilir, (ii) yeniden saçılabilir ve (iii) yeniden üretilebilirler. Bu sebeple bu parçacıkların karakteristik özelliklerinin incelenmesi çarpışmalarda oluşan ve maddenin yeni hali olarak tanımlanan Kuark Gluon Plazma (KGP) ve onu takip eden hadronizasyon safhaları hakkında bilgi verebilir. Ayrıca bu rezonansların farklı yüksek enerjili çarpışma sistemlerinde incelenmesi oluşan ortam boyutlarının rezonans üretimi üzerine etkisini açıklayabilir. Bu çalışmada baryonik rezonanslardan biri ve protonun uyarılmış hali olan Δ(1232)++ rezonansları DPMJET-III olay üreticisi ile 5.02 TeV enerjili proton kurşun (p-Pb) çarpışmaları için incelenmiştir. Ayrıca elde edilen değerler deneysel sonuçlar ile karşılaştırılmıştır. Farklı rölativistik çarpışma sistemlerinde oluşan ortamın bu parçacık üzerine etkisi değerlendirilmiştir.

Published: June 2021

Tourism is a public sector that should be managed seriously to improve the livelihoods of many people. The potential of Aceh's tourism must be encouraged by quality public policies so that all of its potential will be maximized. In fact, there are still many weaknesses in public policies in the tourism sector that have rendered Aceh's tourism potential in vain. This study aims to describe Aceh's public policy in the tourism sector in terms of opportunities and challenges. The research approach used is a qualitative analysis through a literature review that relies on secondary data, namely by collecting and mapping data from government documents in the form of tourism plans, tourism regulations, work reports on tourism and similar studies on tourism policies. The results of the study show that the Aceh Government has seen great opportunities in the tourism sector, especially from halal tourism, but what remains a challenge until now is that the Government of Aceh has not resolved problems related to tourism governance, tourism destination development and tourism branding.
