Modeling, exergy analysis and optimization of cement plant industry
Authors: Abutorabi Hossein , Kianpour Ehsan
Published: July 2022

Cement is the most widely used man-made material. The global cement industry produces about 3.3 billion tons of cement annually. A lot of energy is needed to produce cement. About 200 kg of coal is used to produce each ton of cement. The cement industry also produces about five percent of the world's greenhouse gases. In order to reduce the use of fossil fuels and greenhouse gas emissions, some cement producers have the potential to recover waste heat. The method studied in this research is based on heat recovery from boilers installed at the outlet of clinker cooler and preheater of cement factory. Due to the low temperature of the gases available, three different fluids, water, R123 and R245fa are considered as the operating fluid. Also, energy and exergy analysis is performed in a Rankin cycle and the selection of optimal parameters is considered by using genetic algorithm. By selecting the decision parameters in the optimization of the genetic algorithm such as pinch temperature, evaporator pressure and operating mass flow rate, the optimal values of exergy efficiency were obtained.
The use of PIV methods in the study of two-phase flows in small diameter channels
Authors: Sikora Małgorzata , Ligus Grzegorz
Published: July 2022

The PIV (Particle Image Velocimetry) method is one of the optical, non-invasive measurement methods for measuring fluid velocity and can be used in the study of two-phase gas-liquid flows to determine velocity fields. The velocity distribution of the liquid and gas phases influences the formation of two-phase flow structures and, consequently, the mechanisms of energy and moment exchange in the two-phase flow. The article concerns the application of the PIV method to the assessment of hydrodynamic phenomena occurring during two-phase flow realized in pipe minichannels with an internal diameter d > 2 mm. Fluorescent marker particles with a density close to that of water were used in the research. The preliminary tests were carried out on the adiabatic water-air mixture. The research aimed to check the applicability of PIV methods also in non-adiabatic flows. As a result of preliminary studies, velocity maps of the liquid phase, histograms and velocity profiles in the vertical section of the tested minichannel were obtained.

Maintaining Sustainability and Resilience in Rangeland Ecosystems
Authors: Tuffa Samuel
Published: July 2022

Rangelands contribute to human well-being worldwide. However, its fragile ecosystems are threatened due to inappropriate management that has been leading to its degradation in African rangelands in general and in Ethiopian rangelands in particular. Rangeland degradation is attributable to both natural and anthropogenic causes. Restoring degraded areas by replanting using native species is one of the most promising sustainable rangeland management tools to fight the degradation in the rangelands and enhance resilience in the face of environmental shocks. Restoration improves vegetation cover and biomass yield and enhances other ecosystem services. Native drought-tolerant species have produced promising rehabilitation outcomes and have been recommended for the restoration of degraded rangeland areas. Replanting using native species remains a viable sustainable management option to enhance resilience in the face of environmental shocks. Therefore, to maintain the sustainability and resilient rangeland ecosystems, comprehensive approaches and strategies suitable for rangelands need to be revitalized, developed, strengthened and promoted.

Authors: Sunardi Andhina Ika , Lutfi Nafisatul
Published: July 2022

The current technological development has entered the 4.0 industrial revolutions. This revolution encouraged automation systems in almost all activities and processes . The time constraint for face-to-face interactions in the classroom often makes English learning becomes less effective, especially for classes with diverse levels of English proficiency. In a higher education system which demands active learning, English teachers often find it difficult to help students whose English language competence is below average . In fact , the target of learning English on campus is generally quite high. One of the solutions is that the teaching and learning process uses hybrid method- a learning system that complements face-to-face interactions in the classroom along with distant learning using the internet. Hybrid learning is able to complement the lack of time for face-to-face interactions in the classroom in the form of distance learning with the medium of internet. This paper is the result of the writer’s observations in applying this method when teaching the first semester of the 2021/2022 study period AMA Yogyakarta. This research is a descriptive quantitative research using questionnaires as the data retrieval technique. This research concludes that hybrid learning method can be used in English learning classes with 61,26% of students agree to the method, and 38,7% do not agree even though in general, they prefer face to face interaction. However, it can be a solution for distant learning since it is accessible anytime and anywhere although it requires stable internet connection as its basic requirements.

The Effects of Cryptocurrency Market on Borsa Istanbul Indices
Authors: GÖKALP Bekir Tamer
Published: July 2022

It has been emphasized in many studies that the developments in the crypto money markets have a serious impact on the world stock markets. Due to these effects, the fluctuations in the world stock markets have increased, and it has become necessary for investors to follow these markets more closely and determine their strategies according to these developments. In this study, it was examined whether the developments in the crypto money market have an effect on Borsa Istanbul (BIST) indices. For this purpose, data of the three most popular cryptocurrencies Bitcoin, Ethereum and Ripple were used, and their spillover effects on BIST100, BIST30 and banking (XBANK) indices were investigated. Oil prices (WTI) and fear index (VIX) variables were also used as control variables in the study. The findings obtained from the analyses in our study carried out for the period 01/01/2014-31/12/2021 showed that there is a positive spillover effect from the crypto money markets to the indices we examined. While oil prices were found to be statistically significant in all models among the control variables, different results were obtained on the effect of the fear index. The findings show that it is imperative for stock market investors to closely monitor the developments in the crypto money market in addition to track various economic variables, in their investment decisions.

Authors: HAMZAOĞLU Halit , HOŞFİKİRER Erkan Salim
Published: July 2022

Bu çalışma Rusya-İran nükleer enerji ilişkilerinde özellikle 2000-2015 yılları arasında Rusya’nın uyguladığı çok yönlü stratejiye odaklanmaktadır. Söz konusu çok yönlü stratejiyi açıklamak için üç önemli vaka üzerinde durulmaktadır. Birinci vaka olarak, İran’ın 2005’te Batı ile yaşadığı sorunlar ve sonrasında Rusya’nın İran aleyhine uygulanan yaptırımlara katılması araştırılmaktadır. İkinci vaka, 2010’da Batı’nın İran’a karşı uyguladığı yaptırımlarda Rusya’nın Birleşmiş Milletler Güvenlik Konseyi kararlarını kabul etmesi hususu bağlamında ele alınmaktadır. Üçüncü vaka ise 2015’te İran-ABD ilişkilerinde bir yumuşamaya tekabül eden Kapsamlı Ortak Eylem Planı perspektifinden analiz edilmiştir. Burada ifade edilen üç vaka karşılaştırmalı analiz yöntemiyle irdelenmektedir. Çalışmanın teorik arka planını ise hedging stratejisi oluşturmaktadır. Hedging stratejisi, dengeleme ve peşinden gitme (bandwagoning) stratejilerinden farklı olarak devletlerin risklerle dolu uluslararası sistemde büyük devletleri karşısına almaktan ve taraf olarak görülmekten kaçınarak, ekonomik ve bölgesel çıkarlarını olabildiğince arttırmaya yöneldiğine dikkat çekmektedir. Rusya’nın ekonomik pragmatizm ve bölgesel çıkarlar bağlamında söylemsel olarak İran’ın müttefiki olarak hareket ettiğini gözlemlemek mümkündür. Fakat Rusya siyasi elitleri uluslararası ilişkilerde var olan koşulları göz önünde bulundurmaktadırlar. Bu bağlamda İran nükleer sorunsalında davranışsal olarak Batı’yı karşısına almaktan kaçınmaktadırlar.

Published: July 2022

Yasal olarak bağımsız işletmelerin çeşitli resmi ve gayri resmi bağlar aracılığıyla bir araya gelmesi şeklinde tanımlanabilecek işletme grupları, karmaşık yapısı, kendi içerisinde çeşitli işlemler yapmaya elverişli doğası ve yatırımcıların bu işlemleri izlemesinde yaşayacağı zorluk nedeniyle beraberinde vekalet sorunlarını da getirmektedir. Yapı itibariyle finansal raporlama sürecine müdahale etme konusunda daha fazla özgürlük sunan grup yapısı şirket yöneticilerine, azınlık hissedar hakları konusunda daha fazla inisiyatif sağlamaktadır. Temel olarak kazançların kalitesi ve mali tabloların güvenilirliği konusunda ipuçları sunan kazanç yönetimi uygulamalarının önemi grup şirketlerinde görülen karmaşık piramit yapıların varlığı durumunda daha çok artmaktadır. Bu çalışmada Türkiye’de bir gruba bağlı veya bağımsız olarak faaliyet gösteren firmaların kazanç yönetimi uygulamaları 2014-2019 yılları arasında BİST’de faaliyet gösteren firma verileri kullanılarak kantitatif olarak tespit edilmeye çalışılmıştır. Kazanç yönetimi uygulamaları tespitinde düzeltilmiş Jones modelinden yararlanılmıştır. Analiz sonuçları söz konusu dönemde hakim ortağın büyük işletme grubu veya yabancı olduğu firmalarda kazanç yönetimi uygulamalarına daha az gidildiği, diğer taraftan bağımsız firmalarda bu durumun tam tersi olduğunu göstermektedir. Elde edilen sonuçlar Türkiye örneğinde kazançların kalitesinin belirlenmesinde şirketlerin kurumsallaşma düzeyi ve prestijlerinin ortaklık yapısından daha önemli olduğunu işaret etmektedir.

LA MÚSICA CARRANGUERA, EL CAMPO Y LA IDENTIDAD CAMPESINA: VARIACIONES Y CONTINUIDADES DE UN PATRIMONIO CULTURAL
Authors: Garzon Martinez Maria Angelica
Published: July 2022

El artículo problematiza desde el campo del patrimonio cultural las representaciones de campo y campesino elaboradas en la música carranguera, propia de la región central colombiana, con el objetivo de identificar variaciones y continuidades en la transmisión de esta tradición musical. Desde un análisis narrativo recurre a un corpus de líricas compuestas por intérpretes contemporáneos para identificar temas recurrentes en las canciones y las elaboraciones que sobre los mismos se construyen produciendo representaciones en torno a la identidad campesina, el territorio y su universo de significación. Concluye que, a pesar de movilizar ideas elaboradas por élites modernistas de inicio del siglo XX sobre el campesinado como un ser desprovisto, falto de voluntad y sumido en el subdesarrollo, existen líneas de fuga que confrontan tales narrativas desde la idea de un campesino digno, cuidador de la naturaleza, preocupado por las problemáticas del país y que reclama una posición como parte de la historia oficial colombiana.

Due to the minimal contact between lecturers and students in online learning, particularly in science, students must study independently. The significance of individual learning during the CoVD-09 epidemic provides the context for this study. This research intends to identify the profile of junior high school students' independence in scientific learning throughout the academic year 2021-2022. This research is descriptive. This study's population consisted of 116 pupils enrolled in the eighth grade of junior high school. The sample for this research consisted of 37 eighth-grade SMP students selected using a simple random selection procedure. Furthermore, the data gathering approach employed a non-test technique, namely a questionnaire. The analysis of data was conducted using descriptive statistics. The findings indicated that the general average of pupils' freedom in learning was classified as very independent (81%). In addition, 14 students are in the very independent category, which is equal to (40%), 12 students are in the independent category, which is equal to (34%), and seven students are in the fairly independent category, which is equal to (20%), four students are in the less independent category that is equal to (12.9%), and no one is categorized as very less independent than 37 students. This shows that most class VIII students are very independent in their learning.

Türkiye’de miras hukukunun bir sonucu olarak maliklerin hisselik düzeyi, arazi toplulaştırma çalışmalarını her geçen gün zorlaştırmaktadır. Türkiye’de son yıllarda artan oranda arazi toplulaştırma çalışmaları yapılmaktadır. Yapılan arazi toplulaştırma çalışmalarında toplulaştırma oranı istenilen düzeyde gerçekleşmemektedir. Gelişen teknoloji toplulaştırma çalışmalarının hızını artırmıştır. Ancak miras yolu ile ortaya çıkan parçalılık düzeyi toplulaştırmanın başarısını olumsuz etkilemektedir. Yapılan bu çalışmada hisselilik değişiminin arazi toplulaştırma başarısına etkisinin belirlenmesi amaçlanmıştır. Bu araştırmada, Mersin ili Tarsus ilçesinde 5 mahallede yapılan arazi toplulaştırma çalışmaları materyal olarak alınmıştır. Çalışma kapsamında Hisselilik değişimi; Hisse Sayısı Üzerinden Toplulaştırma Oranı (HSTO), Malike Düşen Ortalama Parsel Adedi (MDOPA), Malike Düşen Ortalama Hisse Sayısı (MDOHS), Maliklerin Parsel Durumu (MPD) ve Ortalama Parsel Büyüklüğü (OPB) göstergeleri ile değerlendirilmiştir. Ayrıca hisselilik değişim konusunda arazi malikleri ile anket çalışması yapılmıştır. Arazi toplulaştırma çalışması yapılan 5 mahallede Arazi toplulaştırma öncesi toplam parsel sayısı 6483’den 8300’e, hisseli parsel sayısı ise 4126’dan 7553’e çıkmıştır. Arazi toplulaştırma çalışması ile hisselilik değişiminde önemli derecede artış görülmüştür. Arazi toplulaştırma çalışmasından maliklerin memnuniyet düzeyi oldukça düşü k çıkmıştır.
Propuestas de gestión ambiental para contribuir a la mitigación de los microbasurales en el barrio Nuevo Golf, Mar del Plata (Argentina)
Authors: Ponce Victoria , Padilla Noelia Aymara
Published: July 2022

El crecimiento de las ciudades a nivel territorial y poblacional requiere ser acompañado de una correcta gestión de los residuos, tanto en el traslado como en la disposición final de los mismos. Una de localidades bonaerenses con mayor crecimiento demográfico y urbano es la ciudad de Mar del Plata. Con base en ello, este trabajo aborda la temática de formación de microbasurales en el barrio Nuevo Golf de Mar del Plata, Buenos Aires, Argentina. Se propone como objetivo general, identificar y formular medidas de Gestión Ambiental para mitigar la generación de microbasurales en dicho barrio. Se emplea una metodología cualitativa-cuantitativa, basada principalmente en la localización de microbasurales, su medición, la identificación del tipo de residuos y la realización de 50 encuestas a vecinos en relación a la problemática. La actividad de campo reconoció y localizó 39 microbasurales que constituyen una problemática ambiental ya que aumenta la probabilidad de contaminación del suelo, del aire y del agua. Así también, supone un riesgo para la salud, ya que genera focos de proliferación de microorganismos patógenos y promueve la propagación de roedores. Los resultados permiten contribuir a una propuesta de Plan de Gestión Ambiental a partir de distintas recomendaciones basadas en prevenir, corregir y curar.

Published: July 2022

El objetivo de la investigación fue identificar a través de la prensa escrita los impactos de las olas de calor [OC] y olas de frío [OF] ocurridas en Bahía Blanca durante el período 1961-2020 en el ambiente urbano, en términos de afectaciones, actores y acciones. El proceso metodológico consistió en dos etapas diferenciadas: la primera fue identificar las fechas de ocurrencia de OC y OF a partir de registros de temperaturas máximas y mínimas diarias provistos por el Servicio Meteorológico Nacional [SMN] y la segunda fue buscar, sistematizar y analizar la información de artículos periodísticos de un diario local correspondientes a las fechas de ocurrencia de los eventos. Se observó un aumento en la relevancia de las temáticas relacionadas con OC y OF en las últimas dos décadas de análisis. El impacto de OC en el ambiente urbano se asoció fundamentalmente al suministro energético y a la ocurrencia de incendios. Se propusieron medidas locales de desarrollo sostenible para disminuir la vulnerabilidad urbana ante OC.

Published: July 2022

La autoconstrucción no permitida en Áreas Naturales Protegidas [ANP], es una problemática actual en México, al crecer el riesgo de presentar fenómenos geomorfológicos por las características del terreno conocidos como deslizamientos de tierra; la población en su mayoría por el bajo nivel socioeconómico ocupa las ANP, sin importar las características del sitio.

El objetivo de este trabajo es analizar por medio de modelos preventivos identificar las posibles afectaciones a su patrimonio con base en análisis espacial con Sistemas de Información Geográfica [SIG].

El resultado obtenido es la generación de cartografía temática según las características geográficas y resguardo de zonas amenazadas ante posibles ocupaciones irregulares.

El área de estudio es el ANP La Loma dentro de la colonia Reserva Ecológica Torres de Potrero, los resultados pueden ser replicados en la totalidad de la Ciudad de México [CDMX] e inclusive en otros lugares de América Latina.
Empresas y competitividad en la economía argentina (2000-2020)
Authors: O’Connor Ernesto A.
Published: July 2022

El objetivo de este artículo es analizar la pérdida de competitividad de la economía argentina entre 2020 y 2000, a partir de la evolución de las exportaciones, de la cantidad  de empresas privadas activas, y de la cantidad de empresas exportadoras. La metodología se basa en revistar las fuentes de datos acerca de empresas argentinas, elaborados por organismos oficiales. Los resultados indican que hubo una caída de la competitividad a partir del análisis de la evolución de la cantidad de empresas privadas formales, la cantidad de empresas exportadoras y la performance exportadora relativa de una serie de países de la región. Esto permite afirmar la validez de la hipótesis, sobre todo en el período de estanflación que comenzara en 2012 y continúa hasta la actualidad, quedando fuera de las causas el relativo estancamiento del comercio mundial en los ‘2010.
Atrial fibrillation as a risk factor of cognitive impairment. Review
Authors: Antonenko K. V. , Flomin Y. V. , Antonenko A. V. , Vakulenko L. O. , Sokolova L. I.
Published: July 2022

Atrial fibrillation (AF) and cognitive impairment (CI) are now common problems, especially among the elderly. Numerous studies in recent years demonstrated the relationship between AF and CI, including dementia. Given the increasing prevalence of AF with age and aging, the number of people with CI is prognosed to increase.
Leading pathogenetic factors that play a role in the development of CI in AF include focal lesions (macro‑ and microinfarctions, microhemorrhages), cerebral hypoperfusion and systemic inflammatory response. Asymptomatic (hidden, or «silent») cerebral infarcts, which are an accidental finding during neuroimaging, are more common than manifest cerebral strokes and are associated with CI. In patients with AF they are found more often than in people without AF, so, according to many researchers, AF is a significant factor in their occurrence.
It should be emphasized that CI, dementia and brain aging can be prevented. Healthy lifestyles (special attention to a healthy diet, adequate physical activity and normal body weight) and proper treatment of vascular risk factors such as hypertension, diabetes mellitus, hypercholesterolemia and AF are of the utmost importance for maintaining healthy brain. Recent studies have shown the advantage of direct oral anticoagulants over warfarin in preventing the development of CD in patients with AF. Promising areas of research are the study of new (including genetic) biomarkers of high risk of KR, comparison of direct oral anticoagulants to determine optimal prevention of KR, increase patient adherence to therapy, the use of non‑pharmacological strategies to maintain sinus rhythm.
