Published: December 2020

The stability of a vehicle depends on many parameters.The Centre of Gravity is one of the most important in them. If the height of center of gravity from the ground decreases the stability of the vehicle increases. But when the ground clearance is too low it has a chance of collision vehicle and the ground while going on an uneven road or with speed brakes. So, to avoid the collision of a vehicle to ground and increase the stability a mechanism to adjust the ground clearance is to be attached. Also, the lift and drag forces can also be altered using this adjustable ground clearance mechanism. The designers usually fix ground clearance and they try to acquire this by the suspension system. The suspension system has tires, tire air, springs, shock absorber, and other parts to connect the vehicle with the wheels. The present paper describes the significance of using hydraulic oil as a working fluid in an adjustable ground clearance mechanism. Also describes the design and analysis of piston and cylinder rod.

Published: December 2020

Eni oilfield has been experiencing production decline with increase in water output. The implementation of enhanced oil recovery (EOR) can help to extract some percentages of the original oil in place (OOIP). EOR methods are capital intensive and few are environmental hazardous. In a bid to address these issues, this paper discusses on an alternate economically viable enhanced oil recovery technique which has the potential to curb the challenges of other conventional EOR methods.This work suggested a 3 stage approach of applying microbial enhanced oil recovery (MEOR) method for oil recovery in Eni field. The reservoir characteristics in Eni field were studied, the average porosity value of the reservoirs is between 0.238 and 0.241.The reservoir characteristics and parameters were found suitable for the application of MEOR technique for effective oil drainage from the delineated reservoir compartments. Microbial flooding was found to be matured in reservoirs with temperature less than 200 F, brine salinity not more than 100,000 ppm, water depth not more than 3500m and permeability should be above 30 (Md). It was recommended that MEOR approach should be applied in Eni Oilfield for increment of oil production and reduction in water cut due to its efficiency and economic viability.

Authors: Demina I. F. 
Published: December 2020

During the research, there were studied 186 varieties of spring soft wheat of different ecological and geographical origin to develop valuable initial material for new varieties in the conditions of Middle Volga. The studies were carried out in accordance with the methodic recommendations of VIR. According to the duration of the growing season, the samples were divided into three groups: early ripening – 29.4 %, mid-ripening – 45.0 % and mid-late-ripening – 25.6 %. The largest number of high-yielding varieties belongs to the mid-ripening group. Five groups are distinguished according to plant height: above 120 cm – tall, 120-105 cm – medium-grown, 104-85 cm – undersized, 84-60 cm – semi-dwarfs, less than 60 cm – dwarfs. A group of semi-dwarfs showed high resistance to lodging. The yield of productive genotypes in this group is 192-210 g/m2. The analysis of the elements of the yield structure showed the varieties that exceeded the standard in the number of grains in the ear (32.8 pcs.): Annet (38.2 pcs.), Baganskaya 95 (36.5 pcs.), Riks (37.7 pcs.), Lubninka (36.8 pcs.), (Russia, West Siberian Region), Biryusa (37.2 pcs.) (Russia, East Siberian Region), by grain weight per ear – Russian varieties from East Siberian, West Siberian and Lower Volga Regions (0.96-1.52 g), and varieties of foreign selection from North America (0.89-1.64 г). According to the yield the following varieties significantly exceeded the standard variety Kinelskaya Niva (310 g/m2) by 30-54 g/m2 (LSD05 = 22.5 g/m2): Russian varieties Annet, Baganskaya 95, Lavrusha, Tarskaya 10, Pamyati Maistrenko, Omskaya 39, Duet (West Siberian region), Voevoda (Lower Volga region) and Uyarochka (East Siberian region), foreign varieties Aktyube 10 (Kazakhstan) and Granit (Canada). The varieties with complex resistance to the main types of leaf diseases (leaf rust and powdery mildew) have been identified: Norwell, Granit, Dandy, CDC Merlin (Kanada), Lavrusha, Tarskaya 10 (West Siberian Region), Tybalt (Netherlands), Voevoda (Lower Volga Region), Etyud (Ukraine). The identified varieties were used as parental forms in crosses.

Published: December 2020

The research was carried out in 2017-2019 in the conditions of the Smolensk region on sod-podzolic medium loamy slightly acidic soil. The study included 25 varieties and lines of fiber flax of domestic and foreign selection. The mid-ripening variety Impuls (Russia) was used as a standard, whose yield, depending on the test year, was 1.07...1.29 t/ha. As shown by the calculations of the index of environmental conditions, the most favorable conditions for fiber flax developed in 2018 (Ij = +0.46), and stress conditions, caused by excessive moisture during the critical period of plant growth and development (GTC = 1.7), in 2017 (Ij = -0.55). On average, over the years of research, the yield of fiber, depending on the genotype, varied in the range of 1.00...1.97 t/ha. The highest yield on average for three years of testing (1.78...1.97 t/ha) and average yield in contrasting conditions were characteristic of the varieties Cesar, Sinel, Dobrinya (Russia), Marylin (Holland), Andrea, Altea (France). Under favorable weather conditions (2018), a high potential for the yield of flax fiber compared to the average value (121.5...133.3 %) was obtained in the varieties Cesar, Dobrinya, Sinel (Russia), Belita (Belarus), Andrea, Altea (France), Marylin (Holland). Under stressful conditions (2017), high adaptability was found in the samples of the Russian selection Cesar (173.4 %), Sinel (168.0 %), Dobrinya (151.1 %), Tost 3 (128.7 %), Alfa, Universal (127.7 %). The varieties Surskiy (bi = 2.2), Belita (Belarus), l. 323-02 (Russia), Marylin (Holland) − 1.7, Alexandrit (Russia), Andrea (France) – 1.5. Were characterized by high responsiveness to cultivation conditions (bi> 1). Russian varieties with a relatively stable yield: Cesar, Sinel – 0.7, Alpha – 0.6, Lider, Smolich, Tost 3, Universal – 0.5, Impuls – 0,2 did not show reaction to changes in growing conditions (bi <1). Thus, the domestic varieties Cesar, Dobrinya and Sinel have the highest yield of flax fiber and adaptability to the soil and climatic conditions of the Central Non–Black Earth Region. Expansion of fiber flax acreage under these varieties will provide strengthening of the domestic raw material base.

Regime Preferences in Communist Czechoslovakia and the Narrative on the Slovak National Uprising
Authors: Švecova Martina 
Published: December 2020

Most of the participants in the Slovak National Uprising (SNP) were fighting for the ideals of democracy and freedom, for the defeat of fascism and Nazism and for the new Czechoslovak Republic with equal status for the Slovak people within it. They could not have foreseen that communist totalitarianism would be established after the war, one that would try to use the Uprising as a precursor for the socialist revolution (Fremal 2010: 359). The Communist Party, with the support of historians, utilised the legacy of the SNP to justify its political actions. Czechoslovak identity was also constructed through the image of the SNP, whose annual celebrations provided the communists with the opportunity to interpret the legacy of the SNP in various forms. This work deals with the way the communists interpreted the SNP in order to convince the public that this was a people's Uprising intended to lead to social equality and the eventual acceptance of communism in Czechoslovakia in the years 1947,1948 and 1954.

Published: December 2020

Elaborating Critical Thinking Skills in TEFL Methodology subject has become one of the 21st century trends, prioritized in the pedagogic process of language courses. Lecturers as facilitators, motivators, boosters, co-learners and inspirational model are the foundation of innovative creativity to adapt and modify comprehensively, and integrate them in their teaching projects contextually; while, the learners themselves play as the active target of learning agents. This modern TEFL Methodology critically makes use of either authentic texts or real texts that are also confronted by the need to approach texts critically. This was revealed in this research, focused on the learners’ activities that enthusiastically engage critical thinking skills in their learning process. It runs actively, innovatively, creatively, dialogically, democratically and in a critical and interactive atmosphere. The importance of applying critical thinking skills in language learning process can empower learners to maximize the objective of TEFL Methodology learning target both oral and written in accordance with their social context. Learners enter in any task using the target language which contains the elements such as identification, investigation, analysis and problem solving then they must think critically. These kinds of communicative task are commonplace for they engage the learners in authentic communication settings. This is impressive and meaningful for the learners. Thus, recommending success in TEFL Methodology subject – as in life - requires effective use of language practically along with some measure of critical thinking.

Published: December 2020

Background: Hypertension is a serious public health problem and an important research area due to its worldwide high prevalence and being a prime risk factor for cardiovascular diseases and other complications. In developing countries, hypertension is more prevalent among the urban population who lead a sedentary lifestyle.
Objective:This study aimed to investigate the prevalence and risk factors of hypertension among urban dwellers with sedentary life.
Methodology: This cross-sectional study was conducted among the adult population (18 years and above) living in one of the urban areas of Dhaka (Dania Union, Kadamtali Thana), Bangladesh. The study was conducted from January 2018 to October 2018, using a simple random sampling technique for data collection. The adult respondents were enrolled in this study who were staying at home and leading a sedentary lifestyle. Univariate analysis and binary logistic regression analysis were performed to examine the risk factors of hypertension of the study population.
Results: A total of 149 adults were enrolled in this study. The mean (±SD) age of the study population was 51.20 (±14.65) years. About four out of 10 study population were found to be hypertensive in this study. The adjusted logistic regression analysis revealed that increased age groups, i.e., 50 to 60 years old [AOR: 3.11, 95% CI: 1.01 – 9.66] and 60 years old and above [AOR: 5.83, 95% CI: 1.73 – 20.06], and family history of hypertension (AOR: 3.59, 95% CI: 1.34 - 9.63) had a positive and significant association with hypertension. However, people with high socioeconomic status showed 71 percent less likelihood of being hypertensive than the lower ones.
Conclusion: The prevalence of hypertension among the people leading a sedentary lifestyle was significantly higher in this study. Increasing physical activity, maintaining proper antihypertensive medication, and regular follow-up of hypertension for older adults might inhibit the increased prevalence of hypertension in urban areas.

Published: December 2020

As metodologias descritivas convencionais apresentam longo tempo de execução da técnica sensorial, uma vez que requerem treinamento extensivo dos provadores. Como forma de amenizar esses problemas, novas metodologias vêm sendo desenvolvidas, nas quais se permite reunir informações sensoriais dos produtos em tempos mais curtos, visto que essas metodologias podem ser realizadas sem treinamento prévio. Dentre estas novas metodologias sensoriais pode-se citar o teste RATA (Rate All That Apply), uma variante do teste CATA (Check All That Apply), no qual o consumidor é solicitado a indicar se os termos de uma lista se aplicam para descrever o produto e, se o fazem classificam sua intensidade. O objetivo deste estudo foi avaliar a preferência e investigar os perfis sensoriais de quatro marcas de petit suisse pelo método CATA e sua variante RATA através de um painel não treinado (n = 100), comparando estas duas metodologias. Para esse fim, duas abordagens de análise diferentes foram seguidas, tratando os dados como frequências, característico do teste CATA, e avaliação das intensidades dos atributos, característico do teste RATA. Simultaneamente foi realizado um teste de ordenação-preferência para verificar a preferência entre as amostras. Os resultados mostraram que a abordagem RATA resultou em maior capacidade discriminativa em comparação com a abordagem CATA. A amostra PS2 apresentou os menores valores de intensidade para todos os atributos avaliados, exceto para o atributo dessoramento. A marca PS1 foi significativamente diferente (p<0,01) da marca PS2, sendo esta última a amostra menos preferida. As demais marcas foram consideradas intermediárias.
