In this study, the Pb(Zr0.65Ti0.35)O3 (PZT) structure was produced by the solid state reaction method, and a new polarization geometry was used to obtain the radial and thickness modes in cylindrical samples with more efficiency. The polarization procedure was investigated by varying the temperature from 30°C to 80°C. The experimental excitation of radial and thickness modes was observed, and a comparative study was performed with numerical simulations. The comparative analysis of the acoustic response of the cylindrical PZT samples under theoretical and experimental conditions was validated by COMSOL Multiphysics® software. The new polarization geometry technique was used to generate radial thickness and acoustic mixed modes with more efficiency. The results show that the resonance frequency and antiresonance, as well as the impedance mode and phase angle are well adjusted, showing the validation of the technique presented between the theoretical and experimental measurements.

The global data center industry is a huge and rapidly growing sector. This growth has resulted in the development of significant data center clusters in various northern regions. Furthermore, the desire to attract new data center investments has been incorporated into regional development plans and strategies in different parts of the Circumpolar North. Although the policy-makers seem to have great expectations, they and the general public often know little about the industry, which consumes huge amounts of electricity and plays an immense role in the digitalization process that the world is experiencing. This article attempts to increase awareness, knowledge, and understanding of these matters among all relevant stakeholders by introducing data center-related research and development activities and education in the Arctic and the North, as well as research concerning the development of the data center industry in the cold, northern environment. After all, it is often argued that these particular conditions offer advantageous circumstances for the construction of environmentally friendly and sustainable data centers.

The Russian Arctic is at the epicentre of economic, environmental, and social changes. At the same time, the peripheral character of the territory, its strong orientation on primary sector makes the region extremely volatile to suchlike shifts. The study concerns primary sector transformation in the Post-Soviet period when after 1991 significant changes in the economy were observed. The main aim of the paper is to identify the specifics, features and development prospects of the recent primary sector transfor-mation in the Russian Arctic. The statistical methods do not reflect the full picture of the transformation. Firstly, Russia has switched to UN national accounts system only in 1994. Secondly, the Arctic statistics after 2009 for regional level is unavailable. That is why the main method of the research is the expert survey method. The results of the study demonstrate the dominant role of the primary sector and the strong dependence of Russian Arctic regions on these activities. The study identifies the key factors and drivers of the transformation, a specific position of the oil and gas sector and the role of natural resources to be traditionally used in the primary sector. Despite the positive role of economic diversification in the long-term economic development, the corresponding effect for the Arctic regions is not fully expressed. The methodological novelty of the research is an unconventional research method of investigating primary sector transformation on the regional level in the Post-Soviet Russian Arctic, i.e. the expert survey. The method can be applied to other countries and industries.
Sistema de criação de duas espécies de percevejos predadores do gênero Xylocoris Dufour, 1831 e da presa alternativa Corcyra cephalonica (Stainton, 1866) (Lepidoptera: Pyralidae)

Published: March 2021

Anthocorid bugs presents attributes that make them promising agents of biological control. Several species can be reared in the laboratory for later release in the field and in greenhouses, and some of them also exhibit zoo-phytophagous feeding behavior, which favors maintenance in the environment, as occurs with Xylocoris afer (Reuter, 1884) and Xylocoris sordidus (Reuter, 1871). This work aimed to describe a method that optimize the rearing and multiplication in laboratory of Xylocoris spp. and their alternative prey Corcyra cephalonica (Stainton, 1866). The method was adapted replacing inflorescences of Bidens pilosa L., by rolls of hydrophilic cotton inserted in glass jars of 25,0 mL filled with water to maintain the humidity, which is essential to the embryonic development of the insect. The adaptations made to the rearing methods of these predators and the alternative prey have made the breeding of mainly predators more practical and effective.
The level of representation of irrelevant stimuli—Distractor–response binding within and between the senses
Authors: Laub Ruth , Merz Simon , Dröschel Helena , Frings Christian
Published: March 2021

Binding theories assume that features of stimuli and executed responses can be integrated together in one event file (Hommel, Visual Cognition, 5, 183–216, 1998; Hommel, Cognitive Sciences, 8, 494–500, 2004). Every reencounter with one or more of the stored features leads to an automatic retrieval of the previously constructed event file and hence of the response—even the repetition of a task-irrelevant distractor stimulus can retrieve a previously encoded response. This so-called distractor–response binding effect is typically investigated using a sequential prime-probe design that allows the orthogonal variation of response relation (response repetition vs. resporrevertnse change) and distractor relation (distractor repetition vs. distractor change), while probe response times and error rates are measured as dependent variable. Previous research has shown that task-relevant stimuli can be represented at different levels (e.g., perceptual and conceptual; see Henson et al., Trends in Cognitive Sciences, 18, 376–384, 2014), yet it is not clear at which level of representation distractor stimuli are processed. In the present study, we focused on the level of representation of response-irrelevant distractor stimuli. To this end, a crossmodal distractor–response binding paradigm was used that enables the differentiation between the perceptual and conceptual representation of the distractor by allowing the systematic repetition and change of conceptual distractor features independent of perceptual repetitions. The results suggest that the repetition of perceptual distractor features is indispensable for the initiation of the retrieval process while the sole repetition of conceptual distractor features is not sufficient to start the retrieval process.

Published: March 2021

Several factors that affect the use of fuel in boilers are combustion efficiency, quality of feed water management, calorific value, and the potential for available fuel from oil palm varieties. The purpose of this research is to identify the use of fuel and its potential savings based on variations in boiler efficiency and water temperature that entered the boiler. The materials used in this research are FFB mass balance data and boiler fuel composition. Based on the analysis results, the lowest used fuel mass and the highest fuel savings are found in the DxPLangkat variety with an intake water temperature of 105o C and 80% boiler efficiency. The use of fuel is 4,231 kg/hour with shell savings of 967 kg/hour with a value of IDR 725,701. Fiber savings was 487 kg/hour with a value of IDR 121,751.The highest used fuel mass and the lowest fuel savings were found in the Yangambi derivative variety with an intake water temperature of 85o C and 60% boiler efficiency.The fuel consumption is 5,830 kg/hour with shell savings totalling -380 kg/hour. There is no fiber analysis because it is used up hence additional fuel is needed. Additional fuel can be done by asking for other palm oil mill units or buying. If they buy a shell with a requirement of 380 kg/hour, the funds required are IDR 284,939.

Published: March 2021

The low or non-adoption of improved agricultural technologies might be resulted from inadequate participation of farmers at all stages of the process of benefiting farmers. The current study was conducted in the representative sorghum producing areas of Wollo i.e. Raya kobo, Kalu and Dawa chefa with the objective of assessing farmers’ preference towards improved sorghum varieties and providing a menu of sorghum technologies. The study was conducted in 2019 cropping season having one year duration. Both inferential and descriptive statistics were used to analyze the collected data. Farmers’ perception was assessed using preference ranking and narration. Moreover, Agricultural events such as field days and experience sharing were prepared to capture farmers’ perception about the technologies.  GenStat v.18th was used to analyze the data. Analysis of variance was employed to test the mean difference of yield among varieties. The result of ANOVA showed that improved sorghum varieties Dekeba and ESH1 gave the highest grain yield at respective sites. In kalu and Dawa chefa, farmers preferred Argiti whereas in Raya Kobo, Melkam was the variety preferred by the farmers. From the analysis of Spearman’s rank correlation, there was evidence on coincidence of farmers’ preference and the actual data. Therefore, based on the analysis of farmers’ preference and yield data, improved sorghum technologies Melkam and Argiti can be promoted in the respective districts of the study area.
Russian Historiography of Peasant Entrepreneurship in the Moscow Province
Authors: Бирюкова А.М.
Published: March 2021

Рассматриваются основные вехи отечественной историографии истории предпринимательства крестьян Московской губернии конца XIX — начала ХХ века. Автором прослежены тенденции в изучении данной темы на соответствующих исторических этапах — дореволюционном, советском и постсоветском. В дореволюционной историографии исследовались условия и факторы становления и развития крестьянского предпринимательства, региональная специфика промысловой активности крестьянства. Советская аграрно-историческая наука преимущественное внимание уделяла социально-классовым аспектам, в частности динамике доходов и расходов крестьянского хозяйства, исследуемой в том числе с широким применением историко-статистических методов. В современных условиях историки стремятся к многофакторному междисциплинарному анализу социально-экономического положения подмосковных крестьян. В статье охарактеризованы научные труды и исследовательские концепции в отечественной историографии аграрно-крестьянских аспектов отечественной истории. В итоге автор приходит к выводу, что изучение крестьянского предпринимательства в России конца XIX — начала ХХ века в целом и Подмосковье в частности носило фрагментарный характер. Исследователей интересовали лишь отдельные аспекты предпринимательской деятельности крестьян, такие как мелкотоварное производство, промысловая деятельность, отходничество, земельная аренда, а также сбыт сельскохозяйственной и молочной продукции.

The article treats major landmarks of the history of Russian peasant entrepreneurship in the Moscow Province of the late 19th — early 20thcenturies. The author analyzes the tendencies associated with the investigation of the issue at various historical stages: the prerevolutionary stage, the Soviet stage, the post-Soviet stage. Prerevolutionary historiography focuses on the conditions and factors pertaining
to the development of peasant entrepreneurship, region-dependent specialization of peasants’ trade-related activities. Soviet agrarian history focuses on the issues of social status and class, including the dynamics of peasants’ income and expense, which are investigated via a number of historical and statistical methods. Modern scholars tend to analyze social and economic conditions Moscow peasants lived in. The article investigates research works and research concepts associated with historiography of peasant-related aspects of Russian history. The author concludes that the investigation of peasant entrepreneurship in the late 19th — early 20th centuries in Russia in general and the Moscow Region in particular is rather fragmentary. Researchers focus on some aspects of peasant entrepreneurship, such as small commodity production, seasonal work, land leasing, agricultural and dairy marketing.
From Conservatism to Fascism: Oswald Mosley’s Search for the Idea of the National Resurrection of Great Britain

Published: March 2021

статье анализируется процесс формирования и трансформации политических взглядов Освальда Мосли от консерватизма через социал-демократические идеи к фашизму, который должен был стать движением интенсивного национального патриотизма. Его политические идеи способствовали появлению и легли в основу программ политических партий и организаций Британский союз фашистов, Британский национальный фронт и Британская национальная партия. Общим для этих организаций стала идея о национальном возрождении Великобритании путем радикальных реформ в правительстве и экономике. Проведенное исследование позволило выявить, что Мосли, как и все идеологи фашизма, являлся сторонником активного вмешательства государства
во все сферы жизни общества и расширения полномочий органов исполнительной власти.

The article analyzes the formation and transformation of Oswald Mosley’s political views from conservatism via social-democracy to fascism which was expected to enhance patriotism and national pride. Mosley’s political ideas promoted and facilitated the formation of political parties and organizations of the British Union of Fascists, British National Front, and the British National Party. All the above-mentioned organizations propagated the idea of the national resurrection of Great Britain through radical reforms in the government and economy. The research shows that Mosley, as well as other ideologists of fascism, was a proponent of active governmental intervention in all the spheres of public life and the extension of powers exercised by government executives.

В Южном Подмосковье до сих пор сохранилось несколько десятков разветвленных подземных заброшенных каменоломен, которые обнаруживают и посещают энтузиасты и которые являются объектами спелеотуризма. Протяженность некоторых из них превышает 3–5 км. В настоящее время эти объекты не являются учтенными месторождениями и расположены, как правило, под деревнями. В статье раскрыты геолого-тектонические, геоморфологические и социально-исторические предпосылки развития подземной камнедобычи в нижнем течении реки Пахра. На основе архивных материалов и преимущественно дореволюционных изданий реконструирована история заложения и развития крупнейших подземных каменоломен Московской области ― Съяновских. Установлено, что добыча в каменоломнях велась с начала XVII по конец XIX века. Описано современное состояние подземных горных выработок. Приведена краткая история туристического освоения Съяновских каменоломен.

In the south of the Moscow Region, there are still some dozens of abandoned underground quarries whose forked tunnels still attract enthusiasts and speleo-tourists. Some underground quarries extend over more than 3–5 kilometres. Nowadays, these objects are no longer registered as quarries and are often situated under villages. The article treats geological, tectonic, geomorphological, social and historical prerequisites for the development of underground quarries in the lower flow of the Pakhra River. The author analyzes archival materials and pre-revolutionary publications to reconstruct the history of the Syanovskiye Quarries , the largest underground quarries in the Moscow region. The article maintains that the exploitation of the quarries started in the early 17th century, the quarries were closed in the late 19th centuries. The article describes the present state of the quarries and contains a brief history of tourism-related development of the quarries.

Effects of Sintering Atmosphere on the Optical, Thermal and Electrical Properties of Inkjet Printed ZnxCu(1-x)Fe2O4 Thin Films
Authors: Joon Hoong Lim
Published: March 2021

The effects of sintering atmosphere on the optical, thermal and electric properties of inkjet printed ZnxCu(1-x)Fe2O4 thin films have been investigated. The thin film samples were sintered separately in vacuum and oxygen. The obtained samples were then characterized by X-ray diffraction (XRD), optical band gap, electrical conductivity, Seebeck coefficient and thermal conductivity. XRD analysis showed that the fabricated samples have a cubic spinel structure of zinc copper ferrite regardless of the sintering atmosphere. The electrical conductivity of ZnxCu(1-x)Fe2O4 thin films sintered in oxygen was about 5 % higher compared to ZnxCu(1-x)Fe2O4 thin films sintered in vacuum. The optical band gap shows that the samples sintered in oxygen had smaller band gap compared to samples sintered in vacuum. The electronic band structure simulated through ABINIT shows ZnxCu(1-x)Fe2O4 is an indirect band gap material. A smaller electronic band gap was observed in O2 rich condition and was in agreement with the optical band gap and electrical conductivity test results. Seebeck coefficient of ZnxCu(1-x)Fe2O4 thin films sintered in oxygen remained positive , confirming charge transport by hole carries as p-type semiconductors. A change from p-type to n-type semiconductors was observed when ZnxCu(1-x)Fe2O4 thin films sintered in vacuum.
Systematic Review of Public Acceptance of Solar Policies: A Conceptual Framework of Policy Acceptance
Authors: Mohd Sobri Fatimah Azzahraa' , Ariffin Mariani , Sharaai Amir Hamzah
Published: March 2021

Policy goals for sustainable energy will be hampered without sufficient public acceptance and public support. While there is a growing body of literature on public acceptance for solar energy, most studies tend to investigate public acceptance of new technology, and not on the policies constructed that aims to help successful deployment. It is argued that without policy acceptance, the implementation of the technology is not going to be as smooth as planned. Thus, it is important to understand and reveal the drivers for public acceptance of these policies. A study was conducted with the objective to identify the key factors contributing to solar policy acceptance among individual homeowners. The constructs are then organized in a systematic manner to develop a framework to foothold the study model. This study integrates both the ‘internal’ factors and the ‘external’ factors in one framework that is both comprehensive and feasible to undertake. Following a systematic 4-step process of identification, screening, eligibility, and inclusion, relevant published materials were identified and gathered. The recurring factors contributing to policy acceptance are then extracted and analyzed. The factors are personal norms, environmental concern, economic, social, geographic, personal capability, and house characteristics. The factors were then categorized according to Stern's (2000) Attitude- Behavior-Context (ABC) framework.

Published: March 2021

The problem of freshwater is an issue that has been hot for discussion for decades. The number of industries and the increasing population in the world has caused the need for clean water to increase drastically. This scarcity occurs because 97.7% of the water available on earth contains salt. Only 2.3% contains no salt, and 99.5% of the amount is ice, groundwater, and the atmosphere. With a large percentage of seawater, water needs for human survival can be met by using the desalination method. In this study using a throttling valve and utilizing cold water (secondary product) as a refrigerant to cool the room. This research will also discuss how specific energy consumption and cooling heat are affected by compressor pressure and cyclone pressure to prove how capable and efficient the renewable desalination method is in producing aquadest water, which is expected to help water availability to meet water needs. The simulation results obtained The optimum value of the system specific energy consumption is 287.90 kJ / kg with a compressor pressure value of 10 kPa and a cyclone temperature value of 4 ° C. The optimal value of system cooling heat is 51.01 kW with a compressor pressure value. At 10 kPa and a cyclone temperature value of 2 ° C. The effect of the cooling heat value significantly affects the specific energy consumption required for this system.

Authors: Wan Mohamed Wan Mazlina , Ravindran Nirresh Prabu , Rajendran Parvathy
Published: March 2021

The usage of slots has gained renewed interest in aerospace, particularly on propeller design. Most of the works have focused on improving the aerodynamic performance and efficiency. Modern research on propeller design aims to design propellers with high thrust performance under low torque conditions without any weight penalty. Although research on slotted design has been done before, none has been done to understand its impact on different airfoils on the propeller blade. Thus, this study aims to provide extensive research on slotted propeller design with various airfoil of different properties such as high Reynolds number, low Reynolds number, symmetrical, asymmetrical high lift, and low drag. This work has been investigated using computational fluid dynamics method to predict propeller performance for a small-scale propeller. The slotted blade designs' performance is presented in terms of thrust coefficient, power coefficient, efficiency, and thrust to power ratio. Here, the slotted APC Slow Flyer propeller blade's performance has been investigated for diverse types of airfoils with the shape and position of the slot is fixed which is a square-shaped at 62.5% of the chord length. The flow simulations are performed through three-dimensional computational fluid dynamic software (ANSYS Fluent) to determine the thrust coefficient, power coefficient, efficiency, and thrust to power ratio measured in advancing flow conditions. Findings show that the slotted propeller design composed of symmetrical, high Reynolds number, high lift airfoils can benefit the most with slots' implementation. These improvements were 19.49%, 69.13%, 53.57% and 111.06% in terms of thrust, power, efficiency and trust to power ratio respectively.

Bu çalışma, temel eğitim kurumlarında alınan güvenlik önlemlerinin, okul kazalarına etkisini incelemek amacıyla yapılmıştır. Tanımlayıcı olarak yapılan araştırmanın örneklemini; Millî Eğitim Bakanlığı (MEB)’na bağlı İstanbul İl Milli Eğitim Müdürlüğü bünyesinde yer alan Güngören ilçesindeki 48 temel eğitim kurumunda görev yapan 568 yönetici ve çalışan oluşturmuştur. Veriler; araştırmacılar tarafından geliştirilen toplam 82 soruluk “Temel Eğitim Kurumlarında Alınan Güvenlik Önlemlerinin Okul Kazalarına Etkisinin İncelenmesi Anket Formu” ile toplanmıştır (Cronbach Alpha = 0,823). Araştırmaya katılan çalışanlar; okullarda meydana gelen kazaların büyük bir bölümünün (%79,2) öğrencinin kendisinden kaynaklandığını, tüm okullarda ilk sırada (%84,9) düşme kazalarının olduğunu, kazaların çoğunlukla okul binası dışında ve daha çok okul bahçesinde (%72,9), bina içerisinde ise merdivenlerde (%61,6) ve sınıflarda (%58,8) meydana geldiğini belirtmişlerdir. Özel okullarda devlet okullarına göre daha fazla genel güvenlik önlemi alındığı belirlenmiştir. Bu sonuçlar, çocuk sağlığının korunması amacıyla okullarda yapılan fiziksel düzenlemelerin öğrencilerin yaş gruplarına uygun olması, MEB ile iş birliği sağlanarak tüm okullarda kazaları önlemeye yönelik standartlar oluşturulması, öğrenci ve çalışanlara yönelik bilinçlendirme çalışmalarının yapılması gerektiğini göstermektedir.

Bu çalışma ameliyathane hemşirelerinde aleksitimi düzeyinin belirlenmesi ve iletişim becerilerine olan etkisinin değerlendirilmesi amacıyla yapıldı. Kesitsel türde yapılan araştırma, Haziran-Aralık 2019 tarihlerinde Türkiye’nin Doğu Karadeniz Bölgesinde bulunan üç hastanede gerçekleştirildi. Araştırmaya katılan 101 ameliyathane hemşiresi araştırmanın örneklemini oluşturdu. Araştırmanın verileri Sosyodemografik bilgi formu, Toronto Aleksitimi Ölçeği (TAÖ-20) ve İletişim Becerileri Ölçeği-Yetişkin Formu (İBÖ-YF) kullanılarak toplandı. Verilerin analizinde SPSS 23 paket programı kullanıldı. Araştırmaya katılan hemşirelerin yaş ortalaması 35.73±7.35 ve %73.3’ü kadındır. Hemşirelerin %84.2’sinin aleksitimiyi daha önce duymadığı ve %69.3’ünün iletişim becerileri ile ilgili eğitim almadığı belirlendi. Hemşirelerin orta derecede aleksitimik oldukları ve aleksitimi puanları ile iletişim becerileri puanları arasında negatif yönde orta düzeyde anlamlı bir ilişkinin olduğu görüldü (r:-0.48, p=0.04). Ameliyathane hemşirelerinin aleksitimi konusundaki farkındalıklarının arttırılması ve iletişim becerilerinin güçlendirilmesi gerektiği sonucuna varılmıştır. Bu konulara ilişkin eğitimlerin düzenlenmesi ile hemşirelerin, hasta ve ekip üyeleri ile olan iletişiminin etkili bir şekilde sürdürülmesi sağlanabilir.

Published: March 2021

Bu çalışmanın amacı 112 acil sağlık çalışanlarında eşduyum yorgunluğu, eşduyum tatmini ve tükenmişliği incelemektir. Araştırmada betimsel ve ilişkisel tarama modelinden yararlanılmıştır. Araştırma Kayseri İli Sağlık Müdürlüğüne bağlı olarak hizmet veren 41 acil sağlık hizmetleri istasyonunda çalışan 345 personelle gerçekleştirilmiştir.
Verilerin toplanmasında “Çalışanlar İçin Yaşam Kalitesi Ölçeği” kullanılmıştır. Değişkenler arasındaki ilişkileri belirlemede Pearson korelasyon analizi gerçekleştirilmiştir. Bireysel değişkenlere göre eşduyum yorgunluğu, eşduyum tatmini ve tükenmişlik düzeylerinin farklılığını değerlendirmede ikili karşılaştırmalarda t test, ikiden fazla grubu karşılaştırmada tek yönlü ANOVA testinden yararlanılmıştır. Parametrik koşulların sağlanamadığı durumlarda grupları karşılaştırmalarda Kruskal Wallis H testi kullanılmıştır.
Araştırma sonuçları 112 acil sağlık çalışanlarının büyük çoğunluğunun eşduyum yorgunluğu ve tükenmişlik için yüksek ve orta riskte olduklarını göstermiştir. Aynı zamanda çalışanların yaklaşık dörtte birinin (%22,3) eşduyum tatmininde düşük potansiyele sahip olduğu bulunmuştur. Eşduyum yorgunluğu ve tükenmişlik arasında pozitif ilişki, eşduyum tatmini ve tükenmişlik arasında ise negatif yönde bir ilişki belirlenmiştir. Ayrıca kadınların tükenmişliklerinin erkeklerden daha düşük olduğu, paramediklerin diğer unvanlara sahip olanlardan eşduyum tatminlerinin daha yüksek olduğu saptanmıştır. Çalışılan birimdeki hizmet süresinin çalışanların eşduyum yorgunluğu, eşduyum tatmini ve tükenmişliğini anlamlı olarak farklılaştırmadığı görülmüştür. Araştırmadan elde edilen bulguların ışığında kurumların çalışanlarına psikolojik destek ve düzenli eğitim vermeleri önerilmiştir.

Perananan Dianoia di dalam Kekudusan Ditinjau dari 1 Petrus 1:13-16

Holiness is a familiar topic for Christians, of course. Even among believers today, churches usually emphasize holiness only in terms of morals, ethics, and good works. So it is not surprising that behind what appears on the outside, often the life of a believer hides heinous sins. Even the lives of servants of God, pastors, and church leaders are not immune from hidden corruption. A priest who is 50 years old, can molest a minor for years without being caught. This was even done under the guise of being a servant of God where the victim at that time became a student or child under the suspect's supervision. Seeing the reality of life like this, the writer believes that holiness cannot be seen as merely an external morality, but there is something deeper at play in it. Previous literature has attempted to explain what holiness is. This research tries to find the importance of διανοία in holiness by using the exegetical method, namely the interpretation of the verse by verse on the letter of 1 Peter 1: 13-16. By seeing the existence of διανοία (mind) which mainly contributes to holiness which then transforms one's actions to become holy. So the author took the wrong example of the text in 1 Peter 1: 13-16. The author analyzes the text and produces four points: first, διανοίας fully hopes on the grace of God. second, tighten διανοίας. Third, διανοίας is not indulgent. Fourth, Result of διανοίας. From the four points, the writer will explain how important διανοίας is in holiness.
