Authors: Belém Ronaldo Alves , Oliveira Cristiane Valéria , Veloso Maria das Dores Magalhães
Published: May 2021

O extremo Norte de Minas Gerais se encontra em uma faixa ecotonal localizada entre os biomas Cerrado e Caatinga. É nesse cenário marcado pela abundância de diversas fitofisionomias que se localiza o Parque Estadual da Mata Seca. Visando compreender melhor a interação solo/planta/sociedade, este trabalho teve como objetivo analisar a influência dos fatores pedológicos e antropogênicos sobre as características florísticas, fisionômicas e estruturais dos componentes vegetacionais da área de estudo. Todos solos são eutróficos e a presença de Ca e Mg foi importante para explicar o porte da vegetação. Os fatores antropogênicos, como o corte seletivo de espécies e os desmates cíclicos nas pastagens, se destacaram como os mais relevantes na explicação das diferenças entre as formações vegetais do parque.  O Parque Estadual da Mata Seca apresenta grande riqueza florística que se expressa em 83 espécies distribuídas em 25 famílias. As famílias floristicamente mais ricas foram a Fabaceae, a Bignoneaceae e a Euphorbiaceae. As fitofisionomias mais preservadas e com solos mais férteis apresentaram maior porte e densidade.  Os Solos mais rasos e a ação antrópica favorecerem a redução do porte e a densidade dos indivíduos. Esses resultados evidenciaram a influência dos fatores edáficos e antropogênicos sobre as fitofisionomias do parque.

Characterization and Distribution of Cenozoic Polygonal Fault: Case Studies in West Africa and Vietnam Continental Margins
Authors: Le Anh Ngoc
Published: May 2021

The Cenozoic sequence of offshore Cameroon and Vietnam has been analysed based on newly 1500 km2 3D seismic data (Kribi-Campo basin) and 75 km 2D seismic data (Hoang Sa basin). Polygonal faults are widely developed in both passive margins and have relatively similar characteristics. These highly faulted intervals are up to c. 1000 m, characterized by normal faults with a throw of 10-20 ms TWT and 100 m - 1000 m spacing, displaying a polygonal pattern in the map view. Polygonal faults in the Kribi-Campo basin developed almost in the entire Cenozoic sequence mainly in two sets, one in deep section and one in shallow section whereas the Hoang Sa basin developed the polygonal fault only in the shallow section up to the seafloor corresponding to the Pliocene- Pleistocene sequence. In the Kribi-Campo basin, polygonal faults are developed extensively in the high gradient slope (3.4o) which is relatively rare in the low gradient slope (0.7o). Hoang Sa basin shows the widespread polygonal fault except for the area of canyon occurrence. The occurrence of thick and widespread polygonal fault formations associated with the low amplitude reflections suggests the interpretation of fine-grained sediments, thus possibly great seal potential for the study areas.
Enhancing Engineering Properties of Expansive Soil Using Marble Waste Powder
Authors: Abdulla Rozan , Majeed Nadhmiah
Published: May 2021

Owing to its propensity to swell when in contact with water, expansive soil causes severe structural problems and shrinks when they dry out. Soil stabilization is a well-known method used to enhance the soil's physical and engineering properties and is commonly adopted for improving soil structures. The mechanical stabilization of different soils is evaluated by adding varying proportions of marble dust (10, 20, 30 percent) of Penjwen, Said Sadiq and Pirmam marble waste powder) to expansive soil. Shear strength and consolidation parameters, such as void ratio, compression index, and sample swelling index, were determined as basic properties. The marble dust is obtained from the cutting and grinding of real marble from the Erbil marble factory in the experimental program. The addition of marble dust decreases the swelling percentage, with an increase in the percentage of marble powder in swelling soils. It is concluded that the swelling in Bastora soil is more than that of Erbil Airport soil, based on the swelling index studies.
Mechanical Rock Properties Estimation for Carbonate Reservoir Using Laboratory Measurement: A Case Study from Jeribe, Khasib and Mishrif Formations in Fauqi Oil Field
Authors: Abdul Aziz Qahtan , Abdul Hussein Hassan
Published: May 2021

Estimation of mechanical and physical rock properties is an essential issue in applications related to reservoir geomechanics. Carbonate rocks have complex depositional environments and digenetic processes which alter the rock mechanical properties to varying degrees even at a small distance. This study has been conducted on seventeen core plug samples that have been taken from different formations of carbonate reservoirs in the Fauqi oil field (Jeribe, Khasib, and Mishrif formations). While the rock mechanical and petrophysical properties have been measured in the laboratory including the unconfined compressive strength, Young's modulus, bulk density, porosity, compressional and shear -waves, well logs have been used to do a comparison between the lab results and well logs measurements. The results of this study revealed that petrophysical properties are consistent indexes to determine the rock mechanical properties with high performance capacity. Different empirical correlations have been developed in this study to determine the rock mechanical properties using the multiple regression analysis. These correlations are UCS-porosity, UCS-bulk density, UCS-Vs, UCs-Vp Es-Vs, Es-Vp, and Vs-Vp. (*). For example, the UCS-Vs correlation gives a good determination coefficient (R2= 0.77) for limestone and (R2=0.94) for dolomite. A comparison of the developed correlations with literature was also checked. This study presents a set of empirical correlations that can be used to determine and calibrate the rock mechanical properties when core samples are missing or incomplete.
Analysis of Correlation and Coupling between El Niño-Southern Oscillation and Dust Storms in Iraq from 1971 to 2016
Authors: Al-Qadi Tagreed Ahmed , Muslih Khamis Daham , Shiltagh Alyaa Gatea
Published: May 2021

This study's main objective is to examine the impact of the El Niño-Southern Oscillation on dust storms in Iraq and trying to find a reasonable synoptic explanation of this relationship. In order to achieve our goal, various data collections related to dust storm days from eight stations in Iraq and the El Niño-Southern Oscillation data over the period 1971–2016 were analyzed. The results showed a negative relationship between dust storms and the El Niño-Southern Oscillation. This correlation means high dust storms are associated with La Niña, while the low dust storms occur during the El Niño event. The coupling between the tropical pacific sector and dust storms in Iraq is perhaps related to the El Niño-Southern Oscillation variations and how they can contribute to the change of the main pressure system values that mainly participate in triggering dust storms and their intensity. The subtropical high-pressure and the Indian monsoon low-pressure systems have been recognized as the responsible pressure systems for dust storms formation.

The Rethinking of Great Britain’s Role: From the World Empire to the Nation State
Authors: Zernetska O.
Published: May 2021

In the article, it is stated that Great Britain had been the biggest empire in the world in the course of many centuries. Due to synchronic and diachronic approaches it was detected time simultaneousness of the British Empire’s development in the different parts of the world. Different forms of its ruling (colonies, dominions, other territories under her auspice) manifested this phenomenon.The British Empire went through evolution from the First British Empire which was developed on the count mostly of the trade of slaves and slavery as a whole to the Second British Empire when itcolonized one of the biggest states of the world India and some other countries of the East; to the Third British Empire where it colonized countries practically on all the continents of the world. TheForth British Empire signifies the stage of its decomposition and almost total down fall in the second half of the 20th century. It is shown how the national liberation moments starting in India and endingin Africa undermined the British Empire’s power, which couldn’t control the territories, no more. The foundation of the independent nation state of Great Britain free of colonies did not lead to lossof the imperial spirit of its establishment, which is manifested in its practical deeds – Organization of the British Commonwealth of Nations, which later on was called the Commonwealth, Brexit and so on.The conclusions are drawn that Great Britain makes certain efforts to become a global state again.

Published: May 2021

In order to meet the load demand of power system, BP based on genetic algorithm is applied to the typical daily load forecasting in summer. The demand change of summer load is analysed. Simulation results show the accuracy of the algorithm. In terms of power supply, the reserves of fossil energy are drying up. According to the prediction of authoritative organizations, the world's coal can be mined for 216 years. As a renewable energy, wind power has no carbon emissions compared with traditional fossil energy. At present, it is generally believed that wind energy and solar energy are green power in the full sense, and they are inexhaustible clean power. The model of wind power solar hydrogen hybrid energy system is established. The control strategy of battery power compensation for delayed power of hydrogen production is adopted, and different operation modes are divided. The simulation results show that the system considering the control strategy can well meet the load demand. Battery energy storage system is difficult to respond to short-term peak power fluctuations. Super capacitor is used to suppress it. This paper studies the battery supercapacitor complementary energy storage system and its control strategy. When the line impedance of each generation unit in power grid is not equal, its output reactive power will be affected by the line impedance and distributed unevenly. A droop coefficient selection method of reactive power sharing is proposed. Energy storage device is needed to balance power and maintain DC voltage stability in the DC side of microgrid. Therefore, a new droop control strategy is proposed. By detecting the DC voltage, dynamically translating the droop characteristic curve, adjusting the output power, maintaining the DC voltage in a reasonable range, reducing the capacity of the DC side energy storage device. Photovoltaic grid connected inverter chooses the new droop control strategy.

Published: May 2021

A system for electromagnetic stimulation of microorganisms' activity from the active sludge of wastewater treatment plants was developed and preliminarily tested. Through electrochemical, gravimetric, XRD, and SEM-EDAX measurements, it was found that austenitic stainless steel 18/8 presents good stability to AC polarization in wastewater. Preliminary determinations performed through the dielectric spectroscopy technique indicated that the activated sludge's microbial flora is sensitive to 50 ± 0.1 Hz. The stimulation system developed and put into service on the biological aerobic treatment bioreactor consists of a pair of polarizing electrodes, made of perforated 18/8 stainless steel sheet, electrically connected to a power supply, which at 50 Hz is capable of debiting adjustable voltages between 5 and 24 Vrms at a maximum current of 5 A. Preliminary in situ measurements showed that following the stimulation of the microorganisms from the sludge suspension, as a result of an applied electromagnetic field of approximately 4.5 V/m at 50 Hz, the metabolism of residues is accelerated substantially (organic residues determined by oxygen demand decrease by about 42 %, nitrogen/ammonium content by about 44% and total phosphorus by about 50 % which results in an increase in free oxygen concentration by about 71 %).
Miniaturisation of Electronic Components and the Problem of Device Overheating
Authors: BĂJENESCU Titu-Marius
Published: May 2021

With the ever-increasing rate of data generation and communication, as well as the constant push to reduce the size and costs of industrial converter systems, the power density of electronics has risen. Consequently, cooling, with its enormous energy and water consumption, has an increasingly large environmental impact, and new technologies are needed to extract the heat in a more sustainable way-that is, requiring less water and energy. Embedding liquid cooling directly inside the chip is a promising approach for more efficient thermal management. However, the electronics and cooling are treated separately, leaving the full energy-saving potential of embedded cooling untapped. By removing the need for large external heat sinks, this approach should enable the realization of very compact power converters integrated on a single chip.

Comparative analysis of the explanatory power of the CAPM and the Fama-French three-factor model on cross-sectional variation of returns on stocks trading on the Official market of the Macedonian Stock exchange
Authors:   Faculty of Business and Economics, South East European University, Besimi Fatmir , Bisheva Ana
Published: May 2021

The amount of literature on factors that explain the cross-sectional variation in average returns is vast, however, the majority of these papers attempt to explain the variation of returns in developed and emerging markets. In that sense, the literature lacks sufficient evidence regarding the variation of returns of frontier markets. The Republic of North Macedonia is considered to be a frontier market and in this paper we aim to empirically test the ability of the Capital Asset Pricing Model and the Fama-French Three Factor Model in explaining the cross-sectional variations of stock returns of securities trading on the Macedonian Stock Exchange. The empirical study is based on monthly returns from January 2011 to April 2021. Additionally, we use annual data obtained from the financial statements of the analysed companies included in this study. Using OLS time series regression we find that both models have limited explanatory power of the cross-sectional variation in expected returns on the Macedonian Stock Exchange. The study shows that only the size factor exhibits some limited explanatory power regarding stock returns. Based on the comparative analysis the Fama-French Three-Factor Model describes the variation of returns on the MSE much better than the Capital Asset Pricing Model.

Authors:   Institute of Botany of the Academy of Sciences of the Republic of Uzbekistan, А.Adilov B.
Published: May 2021

Long-term changes in the plant biomass of the dried bottom of the Aral Sea and the Karakalpak part of the Ustyurt plateau were determined. Despite the drying of the Aral Sea 50 years ago, primary and intermediate stages of vegetation haloseries dominated by annual and shrub halophyte fraction remains as the main directing force of succession. The emergence and increase in the area of "zero" or arid local territories after the 1990s is observed in the central, especially southern part of the Karakalpak Ustyurt. In contrast to the formation of vegetation on the drained bottom of the Aral Sea, long-term changes in the biomass of various natural-territorial complexes of Ustyurt are characterized by a negative correlation with a reduction in the area of mirrors over the past 30 years.

A Magnesium Oxide-based defluoridation technique using MgO-CaO-Calcium Chloride and pH adjustment by Sodium Bisulphate has been suitably modified for use with fluoride contaminated local groundwater having high alkalinity. Taking into consideration the high bicarbonate concentration in raw groundwater the proportion of the lime has been changed. It was found that sodium bisulphate was not suitable for pH adjustment due to the high concentration of sulphate in the pH adjusted water. Therefore dilute HCl was used instead. Six trials of the adapted defluoridation technique have been carried out in the laboratory successfully at a 50-litre scale.

Se realiza inicialmente un breve recorrido histórico sobre el cartel de cine, se repasan los diversos estilos en los que se inscriben; además de establecerse una definición, tanto conceptual como gráfica. A tal efecto, se enuncian los elementos gráficos y tipográficos que lo conforman y se estudian siguiendo las corrientes norteamericanas y europeas. El cartel de cine se presenta como una síntesis visual del argumento fílmico y de la identidad visual de la película. Debido a esta vinculación entre la imagen representacional y el contenido del film se analizan varios carteles, examinando sus aspectos gráficos en relación a la representación del paisaje en los mismos. La ausencia o presencia de esta representación paisajística, y su interacción con el resto de elementos que conforman el cartel, revelan la importancia que esta ha tenido en su uso fílmico.

La sostenibilidad vinculada a los procesos de creación es una responsabilidad que los diseñadores deberían asumir. Desde el siglo pasado, grandes teóricos como Victor Papanek, han ayudado a sentar las bases del ecodiseño para establecer criterios de sostenibilidad medioambiental, facilitando la consolidación de la ética del diseño y su relación con las problemáticas sociales. En las primeras décadas del siglo XXI estos principios no sólo perduran, sino que se desarrollan y adaptan para atender a las nuevas exigencias desde las diferentes áreas del diseño. En este artículo revisamos cuándo se formulan dichos principios y cómo se aplican en la actualidad.
(Re)existências POC: modos de subjetivação e ativismo
Authors: Pereira Cleber Sales , Prado Guilherme Augusto Souza
Published: May 2021

O termo POC remonta à década de 1970 quando era utilizado para se referir pejorativamente aos homossexuais do sexo masculino com performance e traços afeminados. A expressão passou por um período de remissão e voltou recentemente a ser utilizada nas redes digitais de comunicação, sendo apropriada e ressignificada pela população LGBTQIA+ em um processo que a coloca em proximidade com os estudos/ativismo Transviados. O presente trabalho busca analisar o podcast POC de Cultura a partir de algumas ferramentas da abordagem foucaultiana da Análise do Discurso, entendendo o podcast como um dispositivo de auto-enunciação política no qual podemos mapear a emergência e criação de novos modos de agir, fazer, consumir, desejar e de novas verdades. Assim, nos atentamos às maneiras pelas quais a positivação do termo POC e a militância empreendida no programa resultam em efeitos ético-políticos. Partimos da noção de corpos abjetos em uma série de processos de ressignificações e ativismo POC.

The article presents the data of studies of the state of forest soils under spruce stands. The research was carried out on the territory of the Udmurt Republic in the most common types of forest – spruce forests. To assess the soil horizons, soil sections were laid, chemical analysis of the soil was carried out, by determining the main indicators, such an important element of forest soils as forest litter was analyzed. It was revealed that the dark coniferous forests of the republic were formed on sod-podzolic soils. These soils are characterized by an acidic reaction of the soil solution and a low content of basic nutrients. In the context of the development of transport infrastructure, a high content of potassium (225 mg/kg or more) is observed due to the use of KCl as an anti-icing reagent. Soil acidity varies from highly acidic (3.9 pH) to acidic (4.9 pH), due to the influence of coniferous plants. In turn, this can negatively affect the state of the spruce stands.

„Primitív bunkó állatok.” : A hazai őspunk helyzete, fogadtatása és jellege

A Magyar Szocialista Munkáspárt minden apró próbálkozása ellenére az Egyesült Királyság új dühhulláma átszivárgott vasfüggönyön és egyenesen az állami vezetők kompetenciáját, elkötelezettségét és néha akár személyes életét vette célba az 1980-as években. A magyarországi punk mozgalom mindent megkérdőjelezett, és a monolitszerű, öregedő kormány eltörlését hirdette, amelyhez a kormánypárt tudatlansága adta az üzemanyagot. Ugyan az újonnan született punkok hagyták ezt a belső tüzet égni, végig tudvalevő volt, hogy mindennek ára van. Bárki, aki kapcsolatba került a mozgalommal, passzív és nem ritkán aktív megfigyelés alá került, amelyet kihallgatások, letartóztatások és néha bebörtönzések is követtek. Jelen tanulmány Magyarország első punkhullámának rövid, de gazdag történetét próbálja feldolgozni az első zenekarok megjelenésétől a divaton, a médián és a dalszövegeken keresztül a börtöncellák zárjának első kattintásáig.

Tanulmányom a 16–17. századi Kárpát-medence művelődéstörténetének a könyvkiadás és az írásbeliség elterjedésével kapcsolatos hatásait igyekszik röviden összefoglalni. Mivel a tárgyalt korszak jelentős történelmi eseményekben gazdag, és a nyomdaiparban is számos európai ország ért el jelentős fejlődést, terjedelmi korlátokra való tekintettel sok esetben csak érintőleges összefoglalást teszek, a nyomdászat korai korszakára jellemző ősnyomtatványok esetén rövid külhoni és hazai kitekintéssel, hiszen ezek a munkák idővel a magyar könyvterjesztésben is szerepet kaptak. Továbbá egy saját tulajdonban lévő, 1694-es kiadású Panegyrici Latini kötetén keresztül szeretném illusztrálni a könyv és olvasója közötti kötődést ebben a korszakban.

Doa atau berdoa menurut Imam al-Thibi adalah “memperlihatkan sikapberserah diri dan rasa butuh kepada Allah swt”, Tujuan dari penelitian ini ialah untuk memberikan gambaran lebih mendalam tentang doa dari sudut pandang ilmu Tasawuf yang menitik beratkan bagaimana sepantasnya kondisi hati ketika berdoa. Metode yang digunakan dalam penelitian ini menggunakan metode pendekatan kualitatif, dengan jenis penelitiaan kepustakaan (library research). Data yang diambil bersumber dari kitab-kitab klasik, buku-buku, dokumen hingga majalah-majalah terkait pembahasan yang ada. Hasil dari penelitian ini bahwasanya doa diartikan bukan hanya sebagai sebab demi tercapainya suatu hajat atau keinginan dari manusia, melainkan kewajiban yang harus dilaksanakan oleh seseorang dalam kondisi apapun yang menyandang kedudukan sebagai seorang hamba yang lemah dan butuh. Dalam pandangan ilmu Tasawuf, ada yang jauh lebih penting difahami selain dari ungkapan doa sendiri, melainkan adab hati ketika menghadap dalam berdoa kepada Allah swt.

Identifying Challenging Barriers to Farmers’ Adaptation to Climate Change: A Case of Leribe District, Lesotho
Authors: Mofolo Tsepang Clementine , Rethabile Kheleli Mareabetsoe
Published: May 2021

Climate change has become a global issue that most if not all countries around the world are tackling. Its impacts cut across different sectors, but for less developed countries like Lesotho, agriculture is a sector that is being affected the most. Lesotho depends on rainfed agriculture, mostly for subsistence and in part for commercial purposes as a source of income. Research in Lesotho has focused more on the implications of climate change on environmental processes, and less attention has been directed towards farmers as producers of food in an industry that provides livelihood to over 70% of its population. The first approach this article takes is to identify the intent and decision of farmers to adapt to climate change and the barriers that affect these decisions are explored. In identifying challenging barriers to farmers’ adaptation to climate change adaptation, the study was carried out in Leribe district, one of the 10 districts in Lesotho because it is known as the food basket of the country because of its high potential arable land. 138 farmers were purposively sampled to carry out the research, which was conducted using questionnaires administered through face-to-face interviews. From the study, perceptions of farmers that rainfall intensity, duration and frequency has decreased, and that temperatures have become extremely high were recorded. This, according to farmers, had led to impacts of water shortages, increase in frequency of droughts among other impacts. Farmers have adopted measures to minimize these impacts. The intention of farmers to adapt to climate change amidst the impacts exists amongst farmers. The study therefore aims of the study is to identify the potentially challenging barriers to farmers’ adaptation to climate change in Leribe. The conclusions drawn from the study are that in the sense of climate change impacts, agricultural productivity reduced, and seasonal food shortages prevailed. Lesotho’s capacity to grow its own food has dwindled dramatically. The food security policy must lay out plans to boost food production, and there must be cross-sector partnerships to provide necessary assistance for the lowest and most vulnerable farmers at both district and national levels.

Introduction: The aim of this study was to evaluate the effects of intraoperative and postoperative theophyl- line infusion on inflammation in children who underwent open heart surgery with cardiopulmonary bypass (CPB) for congenital heart diseases.

Patients and Methods: This randomized controlled study was carried out with 140 children who underwent open heart surgery with CPB in a tertiary hospital. The patients were randomly enrolled into two groups (the- ophylline group= 70, control group= 70). Following the induction of anesthesia, theophylline infusion was applied to theophylline recipients from the beginning of the operation to the end of the 24th hour after surgery via a central venous catheter (CVC). The patients in the control group were infused with 0.9% NaCl solution at the same volume and duration via CVC.

Results: Postoperative red blood cell distribution width was significantly higher than preoperative values in the theophylline group (p= 0.003), but no significant difference was found in the control group (p= 0.188). In both groups, postoperative vasoactive-inotropic scores, and lymphocyte and platelet counts were lower than preoperative measurements (p< 0.001 for each in both groups). While preoperative white blood cell counts were similar, postoperative values were found to be lower in the theophylline group (p= 0.022).

Conclusion: In pediatric patients undergoing open heart surgery with CPB, the use of intraoperative and post- operative theophylline may be effective in reducing postoperative inflammation, as demonstrated by lower white blood cell counts; but it does not significantly affect other clinical features.
