Estimate of energy loss from internal solitary waves breaking on slopes
Authors: Terletska Kateryna , Maderich Vladimir 
Published: April 2022

Abstract. Internal solitary waves (ISWs) emerge in the ocean and seas in various forms and break on the shelf zones in a variety of ways. This results in intensive mixing that affects processes such as biological productivity and sediment transport. As ISWs of depression propagate in a two-layer ocean, from the deep part onto a shelf, two mechanisms are significant: (1) the breaking of internal waves over bottom topography when fluid velocities exceed the wave phase speed that causes overturning of the rear face of the wave, and (2) the changing of polarity at the turning point where the depths of the upper and lower layers are equal.
We assume that the parameters that describe the process of the interaction of ISWs in a two-layer fluid with an idealized shelf-slope topography are (1) the nondimensional wave amplitude, normalized on the upper-layer thickness; (2) the ratio of the height of the bottom layer on the shelf to the incident wave amplitude; and (3) the angle of the bottom inclination. Based on a proposed three-dimensional classification diagram, four types of wave propagation over the slopes are distinguished: the ISW propagates over the slope without changing polarity and wave breaking, the ISW changes polarity over the slope without wave breaking, the ISW breaks over the slope without changing polarity, and the ISW both breaks and changes polarity over the slope. The energy loss during ISW transformation over slopes with various angles was estimated using the results of 85 numerical experiments. “Hot spots” of high levels of energy loss were highlighted for an idealized bottom configuration that mimics the continental shelf in the Lufeng region in the South China Sea.

Published: April 2022

Background: Aromatase inhibitors (AI) can boost endogenous testosterone production without increasing circulating estrogen levels, as shown with estrogen receptor modulators, Aim and Objectives: The study's goal was to determine the efficacy of aromatase inhibitor medication in improving spermatogenesis in oligozoospemic and azoospermic males, as well as its relationship to sexuality. Subjects and methods: This study was done on eighty man subjects joining the outpatient clinic of Andrology, Kasr El Aini Hospital, Cairo University during the peroid from April 2018 – April 2020, and they were divided into (2) groups, 40 subjects in each group. Results: There was a statistically significant difference in serum total testosterone measured before and after treatment in normal FSH patients with a p value ≤ 0.05. There was a notably not important change in sexual desire questionnaire measured before and after treatment in normal FSH patients with a p value > 0.05, Conclusion: ERs and aromatase share topographic sites in the brain with pheromones, indicating that estrogen influences both early sexual maturation and sexual behavior in adults. Estrogen can maintain libido while also influencing the number of serotonin receptors in the brain, which modulates mood, mental state, cognition, and emotion.

Driven by quarantine boredom, many 18 to 30-year-old Indians have turned to stock trading during the pandemic. India's youth population is driving a boom within the country's investment landscape as millions are piling into stock trading during the pandemic. The coronavirus securities market meltdown in March gave Indian millennials an enormous opportunity to start out investing within the stock exchange. The pandemic which has resulted in people spending more time in their homes might also be another reason for their tilt towards the stock market trading. While the pre-covid period for millennials was less about saving and investment and more about spending, in the post-covid world they seem to be more curious about making and saving money fast through all means possible including risky stock exchange bets and unregulated crypto currencies.
India's various and growing online investment platforms like Zerodha and Upstox have also seen a surge in demand, particularly among younger, less experienced investors, as they lower entry fees and ease access to overseas markets. Technology helps Indian youth access the stock markets like never, Indian brokerage companies say.

Published: April 2022

Coronavirus disease 2019 (COVID-19) is one of the respiratory system diseases with unknown etiology and clinical characteristics. Defects in the liver and kidneys appear to be common in Covid-19 patients. Aspartate transaminase (AST) enzyme, Urea, creatinine, and Alanine Aminotransferase (ALT) enzyme levels are frequently exalted at the start or within the infection. This pretext suggests that Covid-19 interferes with the functions of the liver and kidneys. The current study was aimed to estimate the biochemical biomarkers changes that related to liver and kidney functions, such as ALT, AST, urea, and creatinine, in infected patients. 50 patients were diagnosed with infected between May 1 and 1 August 2020, in Dayala Hospital. 100 samples included 50 control and 50 infected were carried out to evalute the level of biochemical biomarkers (the plasma urea, creatinine, ALT and AST).The results showed increased of ALT, AST, BUN and creatinine levels in the infected samples compare with the control samples. The mean serum kidney parameter (Urea, creatinine ) levels were 57.84±10.46, 1.61±0.18respectively, while the mean value of serum liver enzyme (AST, ALT) levels were 41.94±4.59 and 42.54±4.45, respectively, with high significant different (P<0.001) with control healthy group.

Published: April 2022

Soft talents are those that have to do with how someone operates. Interpersonal skills, listening skills, communication skills, time management, and empathy are examples of soft skills. Any talent that may be defined as a personality characteristic or habit is considered soft. Students should acquire soft skills both for the benefit of their education and for the sake of their professional employment since they are directly related to greater academic accomplishment. This study focused on the benefits of soft skills and why these skills are important for students as well as for the employee. This study also discussed the difference between soft skills and hard skills, the significance of the soft skills, steps to improve soft skills, and the various types of soft skills. Soft skills are very important for students, both in terms of their education and in terms of their future professions. Students who acknowledge the importance of soft skills early on are better able to master their studies, finish their student obligations with ease, make more connections with people who may be important in the future, as well as present themselves more effectively to professors who may play a key role in their career prospects.

Authors: Samson Sharon , Karthiga S.V. 
Published: April 2022

As a means of effective communication, one of the most important qualities to master and improve is speech. One of the most crucial parts of language learning is the ability to communicate effectively. Many language learners find it challenging to explain themselves in spoken language. In any learning circumstance or environment, human psychology plays a significant influence. The ability to communicate in English is heavily influenced by human psychology. The goal of this study was to find the psychological element that has a detrimental impact on English-speaking learners' production. They usually have difficulties in conveying their thoughts in a foreign language effectively. When we are unable to find the right words or phrases to express ourselves, we tend to quit speaking. A solid command of spoken English is required in the modern world of mass media and communication. The purpose of this paper is to emphasise the importance of focusing on elements that influence English-speaking learners' capacity to communicate. A review paper presents the body of research relating to the word expression, the value of expression, the features of speech production, speaking difficulties and factors influencing speech production. According to the literature review, adequate speech instruction has been described as a concern for learners and an area in which more research is required. Educators and researchers may benefit from this study by better understanding the challenges they face while teaching and learning English.

Communication is critical to the success of any firm. Communication, Is an indivisible, essential, and ongoing action, much like the circulatory system in the human body. As a consequence, communication effectiveness becomes an important factor in assessing a group's overall effectiveness. The survival of an organisation is dependent on a number of elements, include command unity, authority and responsibilities allocation, collaboration, and management, all of which need effective interpersonal communications. As a consequence, interpersonal communication has become a company's lifeblood. The importance of interpersonal communication for organizations is explained in this paper.The aspects of social communication include communicators, content, sound, response, background, and channel. Interpersonal communications skills are beneficial in a variety of situations, including romantic relationships, counseling, marketing, management, and conflict resolution. The capacity to communicate with others via efficient listening and conversation is known as interpersonal competence. Interpersonal skills are crucial for students since they allow them to adapt with others and boost their own growth. In general, kids develop interpersonal skills through their professors and peers at school. However, some students still lack interpersonal skills for a variety of reasons, the most common of which is their introverted personality. Sentiment, filtering, a text crammed with information, dismissiveness, cultural variations, and argot are all barriers to effective interpersonal communications that might be overcome by reducing language, regulating feelings, listening closely, and using feedback. This study will aid in the development of strategies to enhance the interpersonal skills in various organizations.

Published: April 2022

The variation in rainfall and its distribution causes high fluctuations in production and productivity under rainfed agriculture. The data generated during last decade by All India co-ordinated Project for Dryland Agriculture were used for developing yield rainfall relationships.
Total rainfall and its distribution affected the yield. Based on the correlations between yield and weekly rainfall from time of seeding, the growing season was divided into different periods. Various models were tried for prediction. The study was carried out for monsoon sorghum crop for four locations, viz., Hyderabad, Jhansi, Udaipur and Akola.
Delayed seeding reduces the yield of sorghum. The crucial periods for rainfall are 8-10,6.12,3.6, 11.13 weeks for Hyderabad, Jhansi, Udaipur and Akola respectively. At Udaipur, high rainfall during 9-11 weeks reduces the yield possibly due to pollen wash and/or lodging. With the models tried, It IS possible to predict the yield of this crop with higher degree of predictability.

Trombocitopenia versus SOFA para predecir mortalidad en pacientes con sepsis en la Unidad de Cuidados Intensivos de un hospital de tercer nivel de Guatemala
Authors: Escobar Jímenez Nancy , Ranero Meneses Jorge , Chocó-Cedillos André 
Published: April 2022

El trastorno de la coagulación más frecuente en la unidad de cuidados intensivos es la trombocitopenia. Teniendo en cuenta el papel fundamental de las plaquetas en la hemostasia y como marcadores de la coagulación intravascular diseminada, una disminución signiﬁcativa en el recuento de plaquetas es alarmante en el contexto de pacientes sépticos, y se sabe que es un predictor de muerte. El objetivo fue comparar la capacidad del recuento de plaquetas con la puntuación Sequential Organ Failure Assessment (SOFA) para predecir la muerte en pacientes con sepsis grave o choque séptico. Se realizó un estudio longitudinal con una muestra de 29 casos consecutivos evaluados durante enero a diciembre de 2015 en la Unidad de Cuidado Intensivo del Hospital General de Enfermedades (HGE) del Instituto Guatemalteco de Seguridad Social. Se realizó recuento de plaquetas y SOFA al primero y al quinto día de hospitalización, documentando el desenlace de los pacientes. El 51.7 % de los pacientes eran hombres y 48.3 % mujeres, con edad promedio (desviación estándar) de 62.0 (16.9) años, mediana de SOFA al ingreso de 10 unidades (Q1=4, Q3=14) y mediana de plaquetas al ingreso de 196,000 (Q1=100,000, Q3=250,000). La asociación univariante entre trombocitopenia y muerte fue signiﬁcativa (p = .021; RR = 2.45, IC95% [1.21, 4.99]). Según una prueba Bootstrap, no existe diferencia signiﬁcativa entre la capacidad predictiva de SOFA y recuento plaquetario (p = .965). Se concluyó que la presencia de trombocitopenia es un predictor sencillo de muerte en pacientes con sepsis grave o choque séptico, con capacidad similar a SOFA.
Entrevista A Lucio Graciano Reca
Authors: De Pablo Juan Carlos 
Published: April 2022

Lucio Reca nació en Buenos Aires, el 25 de julio de 1931. Egresó de la facultad de Agronomía y Veterinaria de la Universidad de Buenos Aires (UBA) en 1953, con el título de ingeniero agrónomo y con medalla de oro. Completó sus estudios en la Universidad de Chicago, donde obtuvo el master en economía en 1962 y el doctorado en 1967. Todos los publicitarios sueñan con que la marca perteneciente a la empresa que los contrató se identifique con el producto mismo. Coca cola por gaseosa, Xerox por fotocopia y Geniol por analgésico, son claros ejemplos de esto. Dentro de la profesión algo parecido ocurre con Reca y economía agrícola. Dedicó sus esfuerzos -tanto en la función pública como en el ámbito académico- a un sólo sector (muy importante, por cierto). Y tuvo el coraje suficiente como para remar contra la corriente de la “sabiduría convencional” en la materia, mostrando sistemáticamente que los productores agropecuarios responden a los incentivos económicos. Típico de los economistas agrícolas y crecientemente atípico entre los economistas generales, en toda conversación con Reca afloran aspectos teóricos, empíricos, técnicos, institucionales, históricos, etc., sin los cuales es difícil entender la realidad. La entrevista comenzó personalmente en Buenos Aires, el 5 de mayo de 2008, y continuó a través del correo electrónico.
India's Theatre Expansion: Use of Sea Power to Balance China's Rise
Authors: Desai Suyash 
Published: April 2022

Issue: Jan-Feb 2021
There are geopolitical, strategic and historical reasons for a competitive and adversarial relationship between China and India. The border dispute is both a symptom and a trigger of this adversarial relationship. While border defences and the use of land and air power along the Himalayan frontiers is essential given the nature of the dispute, they are insufficient to deter China from using military provocations to unsettle India's foreign policy and limit it to a sub-continental power. This paper argues that sea power affords India the best way of managing China in the Indo-Pacific region. The development and demonstration of maritime power, particularly in the Indian Ocean and to the east of the Malacca Straits allow India a range of options in explicit and implicit strategic negotiations with Beijing.

Issue: Mar-Apr 2021
This paper discusses economic policies that have supported a particular kind of agricultural development in Punjab, as well as environment-specific policies, that have sought to deal with various environmental problems arising from that pattern of development. In doing so, we highlight some major environmental issues associated with economic policies in the state, including with respect to water, air, soil and climate change. We analyse why and how economic policy failures, including at the national level, adversely affect environmental quality in Punjab. The aim of this paper is to highlight these issues, as a first step towards identifying policies that may do a better job of protecting the environment.
Nespôsobilosť prezidenta Slovenskej republiky na výkon funkcie – garantovanie funkčnosti ústavného systému či možnosť odstavenia hlavy štátu?
Authors: Domin Marek 
Published: April 2022

Príspevok upriamuje pozornosť na platnú právnu úpravu predpokladajúcu možnosť, že prezident Slovenskej republiky sa počas svojho funkčného obdobia môže stať nespôsobilým na výkon funkcie, s čím Ústava spája nezanedbateľné dôsledky. Cieľom je posúdiť, či existujúca úprava dostatočným spôsobom zabezpečuje riadny výkon prezidentských právomocí aj v prípade, ak by osoba zastávajúca úrad prezidenta nebola na výkon svojej funkcie spôsobilá. Pozornosť je však venovaná aj potenciálnemu zneužitiu súčasnej úpravy. Príspevok preto skúma aj to, či by Ústavou predpokladanú nespôsobilosť prezidenta bolo možné využiť na presadenie určitého rozhodnutia, ku ktorému sa hlava štátu stavia odmietavo, prípadne naopak, k zabráneniu prijatia určitého rozhodnutia hlavou štátu samotnou. Súčasťou záveru príspevku je, v kontexte stručnej komparácie s ústavnými úpravami v ostatných krajinách V4, aj formulácia návrhov de lege ferenda.
