Published: November 2021

Reinforced concrete two-way flat slabs are considered one of the most used systems in the construction of commercial buildings due to the ease of construction and suitability for electrical and mechanical paths. Long-term deflection is an essential parameter in controlling the behavior of this slab system, especially with long spans. Therefore, this study is devoted to investigating the validation of the ACI 318-19 Code long-term deflection limitations of a wide range of span lengths of two-way flat slabs with and without drop panels. The first part of the study includes nonlinear finite element analysis of 63 flat slabs without drops and 63 flat slabs with drops using the SAFE commercial software. The investigated parameters consist of the span length (4, 5, 6, 7, 8, 9, and 10m), compressive strength of concrete (21, 35, and 49 MPa), the magnitude of live load (1.5, 3, and 4.5 kN/m2), and the drop thickness (0.25tslab, 0.5tslab, and 0.75tslab). In addition, the maximum crack width at the top and bottom are determined and compared with the limitations of the ACI 224R-08. The second part of this research proposes modifications to the minimum slab thickness that satisfy the permissible deflection. It was found, for flat slabs without drops, the increase in concrete compressive strength from 21MPa to 49MPa decreases the average long-term deflection by (56, 53, 50, 44, 39, 33 and 31%) for spans (4, 5, 6, 7, 8, 9, and 10 m) respectively. In flat slab with drop panel, it was found that varying drop panel thickness t2 from 0.25 to 0.75 decreases the average long-term deflection by (45, 41, 39, 35, 31, 28 and 25%) for span lengths (4, 5, 6, 7, 8, 9 and 10 m) respectively. Limitations of the minimum thickness of flat slab were proposed to vary from Ln/30 to Ln/19.9 for a flat slab without a drop panel and from Ln/33 to Ln/21.2 for a flat slab with drop panel. These limitations demonstrated high consistency with the results of Scanlon and Lee's unified equation for determining the minimum thickness of slab with and without drop panels.

Published: November 2021

Soft ground improvement to provide stable foundations for infrastructure is national priority for most countries. Weak soil may initiate instability to foundations reducing their lifespan, which necessitates the adoption of a suitable soil stabilization method. Amongst various soil stabilization techniques, using appropriate admixtures is quite popular. The present study aims to investigate the suitability of bagasse ash and stone dust as the admixtures for stabilizing soft clay, in terms of compaction and penetration characteristics. The studies were conducted by means of a series of laboratory experimentations with standard Proctor compaction and CBR tests. From the test results it was observed that adding bagasse ash and stone dust significantly upgraded the compaction and penetration properties, specifically the values of optimum moisture content, maximum dry density and CBR. Comparison of test results with available data on similar experiments conducted by other researchers were also performed. Lastly, a study on the cost effectiveness for transport embankment construction with the treated soils, based on local site conditions in the study area of Assam, India, was carried out. The results are analyzed and interpreted, and the relevant conclusions are drawn therefrom. The limitations and recommendations for future research are also included.

Authors: Silveira Cedric Thomas 
Published: November 2021

Supervised and unsupervised employees are assumed to be quite different. A supervised employee can always fall back to the supervisor in times of need as compared to an unsupervised employee who has to fend for himself in most times. Wishing to find out as to what keeps supervised as well as unsupervised employees going in an organization, I drew up a questionnaire to be filled up by the employees. The questionnaire had six variables which had to be ranked from 1 to 6, with 1 being the most important and 6 being the least important. The variables were Discipline, Growth, Desire to learn, Organizational skills, Dedication, and Motivation. A total of 100 employees were interviewed, 50 who were supervised and 50 who were not supervised. A personal interview was conducted wherein the questionnaire was direct and structured. The results were such among the supervised employees growth was ranked first followed by discipline and desire to learn whereas among the unsupervised employees growth was ranked first followed by desire to learn and motivation.

Published: November 2021

The objective: a study of the features for the formation and functioning of the fetoplacental complex in pregnant women with a history of sexually transmitted infections.Materials and methods. We examined 50 pregnant women with a history of sexually transmitted infections (I group – the main group). The control group consisted of 30 pregnant women without somatic and gynecological pathology, who had vaginal delivery. All pregnant women underwent a comprehensive clinical examination, taking into account complaints, medical history, objective and additional methods of examination. The levels of estriol, cortisol, placental lactogen and progesterone in the blood serum of pregnant women and the state of fetoplacental complex in terms of 18–20th, 28–30th and 38–40th weeks were determined.Results. In the pregnant women in I group, starting from the 18th weeks there was a significant decrease in the secretion of progesterone (160,8±15,9 nmol/L versus 202,4±5,5 nmol/L, respectively; p<0,05), placental lactogen (77,5±13,2 nmol/L versus 91,3±23,8 nmol/L)/ This means that already in these stages of pregnancy there are signs of placental dysfunction in pregnant women with a history of sexually transmitted infections. The changes in the functional state of the fetoplacental complex at the 28–30th weeks are more pronounced, as evidenced by an increase in the frequency of early intrauterine growth restriction (12.0 %), disorders of fetal breathing (11.0 %) and fetal movements (18.0 %) (according to the biophysical profile score assessment); premature of the placenta, increased hormonal insufficiency of the fetoplacental complex and the first signs of hemodynamic disorders (an increased blood flow in the umbilical artery and uterine arteries and a slight decrease in blood circulation in the middle cerebral artery of the fetus). At the final assessment of the condition of the fetoplacental complex at the 38–40th weeks in pregnant women with a history of sexually transmitted infections, a satisfactory condition was observed in 24 % of cases, compensated ultrasound changes occurred in 46.0 % of cases; subcompensated – in 20.0 % and decompensated – in 10.0 % of cases, respectively, which causes a high frequency of obstetric and perinatal complications in this group of pregnant women.Conclusions. The formation and functional state of the fetoplacental complex in pregnant women with a history of sexually transmitted infections, from early pregnancy is characterized by a significant level of functional disorders of the fetus, placenta and the amount of amniotic fluid on the background of pronounced hemodynamic and endocrinological disorders, which requires prevention in the pre-pregnancy period.

Published: November 2021

Статья посвящена практике награждения русских православных священнослужителей за их деятельность в военный период XIX - начала XX века. В публикации изучаются варианты награждения духовенства за военные заслуги, а также указывается возможность для них посмертного награждения и сокращения стандартного трехлетнего междунаградного срока. Исследуется роль духовенства в жизни российской армии и рассматриваются обязанности военных священнослужителей. Большое внимание уделяется примерам отмеченных священноначалием подвигов духовенства, совершавшего свое служение во время Отечественной войны 1812 года, Крымской, Русско-турецкой, Русско-японской и Первой мировой военных кампаний. Известно, что отличившиеся священники награждались специально учрежденными для них особыми императорскими наперсными крестами на Владимирской или Георгиевской ленте. В статье рассматриваются обстоятельства установления этих наперсных крестов в качестве наград, а также возможность использования их священнослужителями как во время богослужения, так и в повседневной жизни. Кроме того, указывается на то, что, согласно сложившейся к началу XIX столетия системе награждения духовенства, труды священнослужителей в обстоятельствах военного времени могли отмечаться традиционным предоставлением права ношения отличительного элемента богослужебного облачения или возведением на очередную иерархическую степень.
The article is devoted to the practice of rewarding Russian Orthodox clergy for their activities during the war period of the 19th - early 20th centuries. The publications study the options for rewarding clergy for military merits, and also indicate the possibility of posthumous rewarding for them and shortening the standard three-year period. Patriotic War of 1812, the Crimean, Russian-Turkish, Russian-Japanese and World War I campaigns. It is known that priests who accomplished feats awarded special imperial pectoral crosses specially designed for them on the Vladimir or St. George ribbon. The article presents the facts regarding these pectoral crosses as a nation, as well as the possibility of using them as a worship service during everyday life. In addition, it is pointed out that, according to the clergy reward system established by the beginning of the 19th century, the work of clergy in wartime circumstances could be marked by the traditional granting of the right to wear a distinctive element of liturgical vestments or raising to the next hierarchical degree.

A Systemic Functional Multimodal Discourse Analysis of English Micro-lectures
Authors: Feng Haili 
Published: November 2021

Lim (2019) states that one challenge for the researchers in multimodal discourse analysis is to describe and discuss the interplay across various semiotic resources. English micro-lectures, as a kind of popular and widespread teaching materials in the information age, are typical multimodal discourses involving multi-semiotic resources. This article adopts the systemic-functional synthetic framework for multimodal discourse analysis from Zhang Delu (2018) to explore the relationship of various modes involved in excellent English micro-lectures and further examine how the semiotic resources cooperate and interact to construct communicative meaning. By analyzing and interpreting the context of culture, the meaning, the lexico-grammar, the media and the substance systems of involved modes in micro-lectures, it proves that English micro-lectures demonstrate complicated intersemiosis and various modes cooperate in a perfect way in meaning construction. This comprehensive investigation of semiotic systems sheds light on teachers’ mode choice and teaching design in producing micro-lectures and students’ learning strategies of micro-lectures in the mobile-assisted learning environment.
