Problems and Risks of Renewable Energy Sources
Authors: Sokolov Yu. I.
Published: August 2021

The article analyzes the problems and risks of new-fangled renewable energy sources in the 21st century, which can radically change the energy picture of the world and to a certain extent reduce the risk of climate change. However, energy generation from wind is usually available 25—35% of the time, from the sun — 10—25%.Renewable energy sources (RES) face the problem of accumulating or supporting capacities that should replace the unstable generation of RES at the time of inevitable failures. RES cannot exist without excess reserve capacities on traditional energy carriers that can quickly increase and reduce electricity production. Abandoning hydrocarbons in the next 30—50 years looks unrealistic if countries want to maintain their competitiveness. The growth of the share of RES in the global energy balance is an extremely politicized phenomenon.The development of renewable generation creates risks for consumers. Especially for large ones. One of these risks is associated with the intermittent, unstable nature of renewable generation, which in recent years has been understood mainly as solar and wind power plants. In addition, to produce more solar panels, wind turbines and batteries for electric vehicles, humanity will need more specific resources — rare earth metals. The production of these metals is unsafe for the environment. It involves the consumption of a huge amount of water and electrical energy.Renewable energy sources may dominate, but it will take centuries. Demand is already growing, but fossil fuels will live long enough.
Are Sports Betting Markets Semi-Strong Efficient? Evidence From the COVID-19 Pandemic
Authors: Meier Pascal Flurin , Flepp Raphael , Franck Egon
Published: September 2021

Abstract: This paper examines whether sports betting markets are semi-strong form efficient—i.e., whether new information is rapidly and completely incorporated into betting prices. We use news on ghost games in the top European football leagues due to the COVID-19 pandemic as a clean arrival of new public information. Because spectators are absent during ghost games, the home advantage is reduced, and we test whether this information is fully reflected in betting prices. Our results show that bookmakers and betting exchanges systematically overestimated a home team’s winning probability during the first period of the ghost games, which suggests that betting markets are, at least temporally, not semi-strong form efficient. Examining different leagues, we find that our main results are driven by the German Bundesliga, which was the first league to resume operations. We exploit a betting strategy that yields a positive net payoff over more than one month.

Agricultural intensification is one of the major causes of water pollution. In recent decades, agricultural water quality degradation has become more severe, which in turn emphasizes the importance of improving and implementing sustainable agricultural practices. Precision agriculture variable rate fertilizer application technology is seen as a strategy to reduce environmental pollution caused by excessive fertilizer usage. Fertilizer input rate is altered within the field in response to factors affecting the optimal application rate. The objective of this study was to investigate the effects of uniform rate and variable–rate (N) fertilizer management on surface water quality. Various physical and chemical water quality parameters at the water inlet, paddy field, irrigation canal, and drainage canals were also examined to evaluate seasonal water quality trends. Water sampling was carried out twelve times between September 2018 and July 2019, involving two cultivation seasons within a total of 60 hectares of paddy field in FELCRA Seberang Perak, Malaysia. All water quality measures fall within classes II to IV of the Malaysian National Water Quality Standards (NWQS) with the exception of P, Al, and Fe. In season one, 64% of P, 46% of Al, and 18% of Fe concentrations were found to exceed NWQS Class IV. However, the percentages were lower compared to season two. During the monitoring period, the average concentration of nitrate and ammonia in variable-rate plots was lower than uniform rate plots in both seasons. Furthermore, temperature, Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), pH, Cu, Fe, K, and Mn were significantly different between the two seasons of cultivation.

El angiosarcoma es un tumor maligno raro que supone el 1-2% de los sarcomas de partes blandas. Aunque la etiopatogenia no es del todo conocida, se han definido varios factores de riesgo que incluyen el linfedema crónico, antecedentes de radiación, carcinógenos ambientales y determinados síndromes familiares. No hay ningún patrón radiológico patognomónico, por lo que para su diagnóstico es obligada la realización de una biopsia con análisis con técnicas de inmunohistoquímica. El único tratamiento curativo es la cirugía, que puede realizarse en un escaso número de pacientes ya que el diagnóstico suele llegar en estadios avanzados.

Published: September 2021

A democracy is considered to be consolidated when no major political grouping attempts to overthrow the democratic regime or promote violence in order to seize any part of the territory from the existing state. Democracy becomes 'the only game on the town’ even when the state faces economic and political difficulties and challenges, all political groups believe and seek to find a solution within the constitutional order and democratic procedures. Namely, before any situation and difficulty in the state, the political forces in the country do not seek to solve problems by undemocratic means.
In addition to the main factors mentioned by various authors, in the case of Kosovo, a key problem for the consolidation of democracy, consolidation and positioning in the international arena is the process of normalization of relations with Serbia and cooperation and effective functioning of the three main constitutional institutions; The Assembly, the President and the Prime Minister of Kosovo, as the main pillars of the system policy based on the principle of separation of powers.
In principle, their greatest contribution to the consolidation of democracy in Kosovo is, the election and exercise of constitutional functions is done in accordance with the principles and norms set by the Constitution, enjoys the confidence of the majority of the population in the country, and there are no significant political forces and nor the attitudes of the public trying to replace democracy with authoritarian forms of government. In other words, echoing the metaphorical expression of American scientist Juan Linz, a consolidated democracy emerges when democracy is the only game in town.

Goods movement using container are quite efficiently assessed because it can carry a great amount of goods fit to container capacity. Freight transportations is a primary component of all supply-chain and logistics systems, but in contrary using a truck as its transportation means causing many problems such as air and noise pollutions, traffic congestions, road accidents and road damage.  Depart from this facts, so government is looking for another means of freight transporter which more efficient with a bigger load capacity advantages. This options goes to train as a solutions of intermodal freight transportations lack. In order to supporting intermodal freight transportations, right now double track of railway is available for Jakarta – Surabaya route (Northern line route).  By now, noted that freight transportation with double track railway frequency is potentially increase to 15 trip per days with capacity 500 TEU (Twenty feet Equivalent Units) per days and fuel consumptions (with truck) can be thrifted into 115 kl per days also reducing carbon monoxide emission amounts 350 tons per days.  According with an official statements from Directorate General of Railways, Ministry of Transportations, explained that Jakarta – Bojonegoro route on double track railway is fully operated so this paper is conducted to determining feasibility of railway structure performance due to freight intermodal transportations at Bojonegoro – Kalitidu route. Railway structure performance feasibility is observed from loading distributions, rail strength, rail sleeper strength, and railway subgrade endurance to planned freight trains.  As a result of this research obtained that tension force that occurred on rail is 830,10 kg/cm2 <  permitted tension on rail (first class rail) 1325 kg/cm2. So, tension force that occurred on rail is safe. Moment force that occurred on rail bottom is 14521,25 kg.cm < permitted moment force (150.000 kg.cm) Moment force that occurred in the middle of rail sleeper is 58993,978 kg.cm < permitted moment force (93000 kg.cm). Tension force that occurred on above railway subgrade (σ2) is 4,17 kg/cm2 < qu (29,671 kg/cm2). It means that railway subgrade is capable to supporting load of freight transportation operations along Bojonegoro – Kalitidu route.

SOCIAL-ACADEMIC CLIMATE AND ACADEMIC SATISFACTION IN ARCHITECTURAL DESIGN EDUCATION
Authors: Casakin Hernan , Davidovitch Nitza
Published: August 2021

The social climate created in the classroom has been recognized to have important implications for learning. This study was motivated by the explore how design students in the design studio compared to other other architectural courses view their social-academic climate.
Despite the role played by social climate in classroom, some have argued that classroom climate has been largely ignored in studies of higher education and most studies on classroom climate explore the perceptions of teachers rather than views of students themselves. The present study focuses on social-academic climate and its significance in architectural studies and its effect on academic satisfaction.
A survey was conducted of students of architecture, following an approach developed by Moos (1970), who claimed that behavior is largely affected by environmental and situational factors. The model he constructs presents social climate as a product of bilateral pressure systems - environmental pressures that affect the individual, and pressure that the individual exerts on his or her environment. This study evaluates social-academic climate and academic satisfaction in an academic architectural program, focusing on a comparison of perceptions of students in the design studio and traditional classes, based on the eight dimensions proposed by Moss (1979).
Findings shed light on the importance that students attribute to the measures of social-academic climate. These factors (specifically, students' involvement, competence, innovation, and teacher support) were rated higher in the design studio than in the courses. Social-academic climate measures such as involvement, order and organization, teacher's control, and orientation of the learning material were higher in the first year than in more advanced years. Academic satisfaction was higher in the first year design studio. Ratings of order, organization, and teacher support were the major predictors of students' academic satisfaction with the architectural program.
Key words: academic satisfaction, architecture, classroom, design studio, learning environment, social-academic climate.
DISPLACED VALUES: FROM REMEMBRANCE TO RESILIENCE
Authors: Franzenburg Geert
Published: August 2021

The different considerations of this study analyze in biblical tradition and modern times experiences of displacement and their consequences for educational purposes and resilience. Exemplified by Baltic experiences, it demonstrates how memory constructs coping strategies, which can be transferred into models of enculturation and value-education. Following the stages of the Biblical story of Jewish exile and diaspora, the considerations analyze, how modern people in situations of crisis, transition, mobbing or displacement can draw benefit from the existential experiences memorized in these narratives and actualized in rituals as a memory-culture and process of enculturation. In this context, different memory cultures, focused on a common situation, underline different expressions of remembrance and suggest different approaches to cope with them: symbolic, ritualized, narrative. In this study the Exile- and Diaspora-oriented EXODUS, exemplified by the Baltic exile before and after 1945, facilitates a framework for educators to identify and integrate experiences of exile and diaspora into a concept of enculturation, which combines holistic exercises in non-violent communication, awareness, creative work, intercultural discourse and similar experiences. Furthermore, it assists them to facilitate opportunities to make helpful experiences in their own diaspora-like framework. Key words: Baltic, diaspora, enculturation, Exodus, resilience.

Background: The circulating rare cell population is diverse and rich in diagnostic information. Its characterization and clinical exploitation by cell-based liquid biopsy is an ongoing research task. Bone marrow is one of the major contributors to the peripheral blood rare cell population and, consequently, determines individual rare cell profiles thus depending on bone marrow health status. Bone marrow damage has been associated with aggressive or late-stage systemic diseases and egress of various bone marrow cells into the blood circulation. The association of quantity and heterogeneity of circulating erythroblast with bone marrow damage is of particular interest.
Methods: Circulating CD71high/CD45-/Hoechsthigh blast cells from healthy, noncancer- and cancer-afflicted donors were enriched by CD45 depletion and analyzed by immunofluorescence microscopy.
Results: A new finding of aberrant and mitotic circulating erythroid-like cells that appear similar across blood donors afflicted with various systemic pathologies is reported. Further presented is a classification of said erythroblast-like cells in nine subcategories according to morphological differences between phenotypically similar cells.
Conclusion: Aberrant and mitotic bone marrow-derived rare circulating erythroid-like cells can be detected in the blood of afflicted individuals but not in healthy donors, suggesting the cause of bone marrow damage.

Günlük hayatta sıra beklemek, oluşan müşteri kitlesine anında hizmet verememekten kaynaklanmaktadır. Beklemek müşterilerde memnuniyetsizliğe sebep olur, bu nedenle bekleme sürelerini dolayısıyla da memnuniyetsizliği azaltmak için hizmet sistemleri üzerinde çalışılması gerekmektedir. Beklemelerin en çok görüldüğü yerlerden bir tanesi de yemekhanelerdir. Özellikle üniversitelerde öğlen saatlerinde kısıtlı bir zaman diliminde çok sayıda öğrencinin yemekhaneden hizmet almak istemesi sonucunda uzun kuyruklar oluşabilmektedir. Bu çalışmada öğlen saatlerinde uzun kuyrukların gözlemlendiği bir üniversite öğrenci yemekhanesi için Arena simülasyon yazılımında mevcut durum için model kurulmuş, mevcut durum incelenerek beklemeleri azaltacak alternatif senaryolar geliştirilip denenmiştir. Çalışma sonucunda yoğun bir günde mevcut durumda öğrenciler sistemde toplam 40 dakika geçirmekte 17 dakika beklemekteyken alternatif senaryolar ile toplam sürenin 24 dakikaya bekleme süresinin ise 1 dakikanın altına indirilebileceği görülmüştür.

Published: September 2021

VUCA (Volatility Uncertainty Complexity Ambiguity), bizi bugünlere getiren doğruların yarına götürmeyeceğini ifade eden bir akronim terim olmakla birlikte, VUCA ortamı iş hayatında birçok paradigma değişikliğini getirecek bir geleceğe gebe görünmektedir. VUCA ortamından organizasyonun çıkarlarını maksimum faydaya dönüştürerek çıkmak için yönetim ve iş yapma biçimlerinin “çevik” bir yaklaşıma evrilmesi gerekliliği düşünülmektedir. Çevik yaklaşım dış ortamdaki her türlü değişikliğe adapte olabilecek yetkinliği içinde barındıran proaktif eylemler bütünüdür. Çevik olabilmek; dış ortamdaki her türlü belirsizliği her an okuyabilme, anlamlandırabilme gayreti ile reaksiyon hızını sıfıra indirecek refleks yeteneğimizi artırabilme çabası içinde olmak demektir. Her sene özveri ile yayınlanan “Yıllık Çevik Durum Raporu (Annual State of Agile Report)” çevik yönetim ile alakalı birçok konuyu ele alarak doğrudan uygulayıcıların tecrübelerini anlama fırsatı sunan, geçmişe dayalı bilgi birikimli çalışmalar ve raporlar silsilesidir. Bu çalışmada, çevik dönüşüm tecrübesi yaşamış katılımcıların yıllar içerisinde verdiği yanıtlar incelenmiş, gelecek dönemin iş ve ticaret anlayışının değer kavramları ile yeniden yorumlanarak “müşteri deneyimi” merkezli bir çevik dönüşüm süreci modeli oluşturulmuştur. Çalışmadaki model önerisi çevik yaklaşım ve dönüşüm sürecini benimsemek isteyen işletmelerin karşılaşabilecekleri majör noktalara dikkat çekmek ve sürecin etkin bir şekilde sonuçlanması için gerekli koşulların tesis edilmesini tavsiye eden bir rehber niteliğinde olduğu düşünülmektedir.
