A Review on Phase Change Material as Energy Storage Materials
Authors: Chidambaram P K , Ramachandran M. , Kurinjimalar Ramu , Vidhya Prasanth , Sowmiya S
Published: March 2022

Phase transducers when a large amount of absorbing or releasing the material changes from a solid state to a liquid state it is called 'latent' heat. There are two main classes of transition materials petroleum, organic matter derived from plants or animals and salt hydrates, which are commonly used in natural salts from the sea or from mineral
deposits. A level change is the transition of an object from one stage to another. These changes occur when enough power is supplied to the system, and also when the system pressure is changed. Although Stanford Ovshinsky is generally regarded as the inventor of phase modifiers for data storage, the discovery of phase-changing electrical properties began in the early 1900s in one of Yale's Alan Tower Waterman's little - known and rarely cited pioneers. Salt hydrates are specific Salts that can bind to the water of crystallization tend to change phase during their freezing process. The organic materials used as PCMs are primarily polymers with long chain molecules made of carbon and
hydrogen. A phase transition is a physical process in which an object moves from one stage to another. The change usually occurs when heat is added or removed at a certain temperature, which is called the melting point or boiling point of the material. PCMs are generally divided into three main types: organic PCMs, inorganic PCMs, and eutectics
of organic and inorganic compounds. Any substance that experiences the process of phase change is called phase change material (PCM). Such materials collect, dissipate, or absorb heat when oscillating between solid and liquid forms. When they turn to solid state they expel heat and absorb when they go back to the liquid state. Melting and
evaporation are endodermic processes that absorb or require energy, while freezing and condensing are external heat processes that release energy
Knowledge, education and social change: Exploring efforts to move beyond objectivism and relativism.
Authors: Ali Victor
Published: March 2022

Learning to address the unprecedented, and increasingly existential, challenges confronting humanity requires the development of increased levels of intersubjective agreement about goals, normative principles and values, as well as effort to apply normative ideals to the needs of society. Yet deliberations about such questions have often been hamstrung by tendencies towards either extreme relativism, on the one hand, or rigid orthodoxy, on the other. Drawing on the work of Bernstein (1983), Seung (1993) and others, this article explores efforts to move beyond the traditional dichotomy between objectivism and relativism in processes concerned with the generation and application of knowledge for the purpose of contributing to constructive social change. To gain insight into how such an approach might find expression in an educational setting, the preliminary results of a case study of the approach to ‘moral empowerment’ taken by a Baha’i inspired school in Macau are discussed.

Objective: compare the lipid and anthropometric profiles and physical condition of dancers from two dance groups (folk and modern dance). Methods/statistical analysis: the study evaluated the anthropometric measurements and lipid profile of the members of both dance groups, according to the guidelines of the International Society for the Advancement in Kineanthropometry (ISAK). To determine strength, velocity, and flexibility, different tests were applied; to establish lipid profile, commercial kits were used. Findings: the population had normal lipid profile ranges. With respect to the anthropometric profile, it was found that adipose percentage averages were above those considered normal for the general population. Physical condition was better in Afro-descendant dancers. Conclusion: the different dance types in this study showed beneficial effects on the anthropomorphic, conditional, and lipid variables of the dancers.
Baseline Maps of Autumn Wheat Yield using Geographic Information Systems for The Samtskhe-Javakheti Region
Authors:   Doctoral student  Samtskhe-Javakheti State University, Narimanishvili T.
Published: March 2022

In food production, not only the level of production but also its quality indicators are of great importance. The quality of wheat grains depends on the variety, climatic conditions and cultivation technology. Agro-climatic conditions affect not only wheat yield but also grain quality. In studying the timing of sowing of the wheat crop, we tried to determine the effect of sowing timing and climatic conditions on wheat yield and quality. The vegetation period of wheat was characterized by different natural-climatic conditions, which were manifested by the drought of autumn and the sharp variability of high temperatures in spring. The study used wheat varieties common in the region: Tbilisi 15, Red Doli bread of Akhaltsikhe and Sauli 9. On the content of chemicals in grains, we conducted an experimental study. Phenological observations were made during the vegetation period: emergence, recording, pruning, plant resistance to dormancy, disease resistance. As a result of the analysis of the research, we found: • Based on the data obtained from the studies, we can say that the optimal sowing date of wheat in the Samtskhe-Javakheti region is 1-15 October. • Previously, the optimal sowing dates were considered September 15-October 15. The data we obtained convinced us that wheat sown in September had significantly lower yields than wheat sown in early October (8%, 11%, and 20%). Delayed sowing after October 15 reduces crop yields by 65-75%. • It is important for farmers to reduce the optimal sowing time, which means that sowing should be carried out in a short time, 10-15 days. • Taking into account the optimal dates of wheat sowing in the Samtskhe-Javakheti region will allow us to dramatically increase the yield. In addition, the results of the experiment showed that the quality and yield of grain depend on the dates of sowing, as well as the biological characteristics of the variety, soil-climatic and agrotechnical conditions.

Published: March 2022

As máscaras de protecção facial tornaram de uso obrigatório pela população em geral, nesta época da pandemia de Covid-19 mas a falta de consciência dos danos que advém do descarte incorrecto leva a danos ambientais. Foi proposto como objectivo deste estudo em contribuir os efeitos das máscaras descartáveis quanto a poluição do meio ambiente incentivando o descarte correcto das mesmas. Destaca-se o método de revisão narrativa e acomoda-se como um estudo de natureza qualitativa e teve a observação no local dos acontecimentos e também realizou-se uma busca na base de informações da MEDLINE, SciELO e Google Scholar e não se deixou de fora as recomendações oficiais maioritariamente da Organização Mundial da Saúde. A recolha de informação foi feita com base num questionário. Os resultados desta pesquisa são considerados satisfatório porque respondem aos objectivos traçados para o presente estudo. Concluiu-se que é necessário continuar com as acções de sensibilização da população em matérias de educação ambiental de modo que as pessoas percebam quais são os problemas ambientais que precisam de soluções para que o futuro ambiental não seja prejudicado e ter uma consciência quanto aos impactos ambientais. Continuar também a combater o alastramento da doença e no mínimo reduzir o uso das máscaras descartáveis optando pelo material reciclável como as máscaras caseiras que podem ser reutilizadas. Recomenda-se o descarte das máscaras de forma correcta e que se façam mais pesquisas capazes de educar e sensibilizar as populações sobre a gestão de residuos sólidos.
NEW TESTAMENT APOCRYPHA
Authors: Fai Ebenezer , Olagunju Olugbenga Samuel
Published: March 2022

There was a considerable debate among the early church fathers about which books ought to be included in the New Testament Canon and which ought to be omitted. Those which were omitted from  the New Testament Canon were known as Apocrypha. This paper is eclectic in nature as the researchers use both descriptive and analytical methods. The findings reveal that the reasons for their not being canonized were that they were not inspired and lacked apostolic authorship. Their writings claimed to add missing details of the canonical books, and some wrote just to satisfy curiosity. The findings also reveal the importance of providing extracanonical traditions about the life and teaching of Jesus not found in the canonized books. They provide some information about Jesus and the apostles lacking in the New Testament. They contain traditions that can be etched back to the very beginning of Christianity. They are indispensable to understanding the theological environment of the first century. The study is essential as it educates on the general understanding of which books comprise the New Testament Apocrypha and how they can help one understand some missing information about key New Testament actors not discussed in the New Testament. The researchers recommend that though these writings cannot stand on a par with the canonized books of the New Testament, they should be studied for their rich historicity. Their knowledge contributes immensely to the understanding of the New Testament.

Published: March 2022

When developing software today, we still use old tools and ideas. Maybe it is time to start from scratch and try tools and languages that are more in line with how we actually want to develop software. The Go Programming Language was created at Google by a rather famous trio: Rob Pike, Ken Thompson and Robert Griesemer. Before introducing Go, the company suffered from their development process not scaling well due to slow builds, uncontrolled dependencies, hard to read code, poor documentation and so on. Go is set out to provide a solution for these issues. The purpose of this master’s thesis was to review the current state of the language. This is not only a study of the language itself but an investigation of the whole software development process using Go. The study was carried out from an embedded development perspective which includes an investigation of compilers and cross-compilation. We found that Go is exciting, fun to use and fulfills what is promised in many cases. However, we think the tools need some more time to mature.
A Study on Various Phishing Techniques and Recent Phishing Attacks
Authors: Bhagya Bajanthri  , Mr. Sayeesh
Published: March 2022

Now-a-days internet has become a very unsafe space to deal with. Hackers are constantly trying to gain the user's personal information, and detailed credentials. So many websites on the internet, even though safe, this safety cannot be assured by all websites. These rule breakers avoid abiding by rules, and try to employ methods like trickery and hacking to gain illegal access to private information. To be able to overcome this problem, we need to first understand the intricacies of how the virus is designed. This paper mainly deals with the different phishing techniques and recent phishing attacks that took place during COVID 19. like Link Manipulation, Filter Evasion, Website Forgery, Phone Phishing and Website Forgery. We have also studied a subtle method to perform phishing attacks that makes links appear legitimate, but actually redirect a victim to an attackers website called Convert Redirect. In this paper, we present some phishing examples like Paypal phishing which involves sending an email that fraudulently claims to be from a well known company and Rapidshare Phishing where in the spoofed web page, phishers attempt to confuse their victims just enough to entice them to enter their login name and password. To perform these types of phishing the Phishers uses so many phishing techniques like Link Manipulation, Filter Evasion, Website Forgery, Phone Phishing and Website Forgery. Phishing techniques include the domain of email messages. Phishing emails have hosted such a phishing website, where a click on the URL or the malware code as executing some actions to perform is socially engineered messages. Lexically analyzing the URLs can enhance the performance and help to differentiate between the original email and the phishing URL. As assessed in this study, in addition to textual analysis of phishing URL, email classification is successful and results in a highly precise anti phishing. From the thorough analysis of the research paper, we have understood how phishing attacks work and the different methods employed to carry out the attack. Also, we have studied some of the most recent phishing attacks and measures taken by the authorities to overcome and prevent any such attacks in future.

Published: March 2022

In this research, the combination of the photocatalytic activity of the semiconductor Ag3PO4 and the as-synthesized MIL-101(Fe)@nanocellulose (NC) from agricultural and bottle waste sources exhibited great photocatalytic efficiency. The Ag3PO4@MIL-101(Fe)@nanocelllulose (NC) composite has overcome the disadvantages of pure Ag3PO4 and significantly improved the photocatalytic activity. Structural characteristics, morphology of the materials were analyzed by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscope (EDX), and UV–vis diffuse reflectance spectroscopy (UV-vis DRS) methods. From the obtained results, composite has a narrow bandgap energy (2.45 eV) and excellent catalytic performance in the photodegradation of Tetracycline pollutants (99.7 % after 120 min). It demonstrates the development of new catalysts made from agricultural waste sources that show high stability, ease of fabrication and can operate in natural light for environmental remediation.

Published: March 2022

Статья посвящена созданию математической модели надежности информационных систем, состоящих из объекта защиты и систем безопасности. С целью получения несанкционированного доступа к объекту защиты предпринимаются различного рода атаки. Поскольку процесс функционирования рассматриваемой системы имеет стохастический характер, математической моделью является случайный процесс, представляющий собой наложение альтернирующих процессов восстановления. Анализ модели, рассматриваемой в этой статье, позволил получить асимптотические соотношения оценок: вероятность того, что на цикле регенерации рассматриваемого процесса аварии не было; среднее время наработки информационной системы до аварии.Статья рассчитана на инженеров и математиков, занимающихся вопросами надежности систем, состоящих из объекта защиты и систем безопасности.

The paper covers the development of a simulation model for the reliability of IT systems consisting of a protected asset and a security module. There are various types of attacks to obtain unauthorized access to the protected asset. Since the system under consideration operates stochastically, the simulation model is a random process as overlapping of alternating recovery processes. We analyzed the proposed model and obtained asymptotic estimate ratios: the probability of no-accident state during the recovery stage of the process; IT system mean time between failures.The paper is intended for engineers and mathematicians dealing with the reliability of systems consisting of a protected asset and a security module.
As mulheres na ciência e tecnologia: uma história a ser escrita
Authors: Guedes Raquel da Silva
Published: March 2022

A história feminina na Ciência e Tecnologia foi limitada devido a fatores circunstanciais que delimitaram o espaço como predominantemente masculino, de maneira que até hoje a presença das mulheres nessa área de conhecimento ainda é pequena. Durante séculos a luta feminina por direitos civis e educacionais foi acirrada, sendo vários os eventos históricos em que mulheres foram em busca de oportunidades de formação profissional e à disputa dos lugares de trabalho no mercado, seja porque tinham o ideal de igualdade de gênero, seja porque não aceitaram o discurso de que a capacidade da mulher seria inferior a do homem. O presente trabalho de pesquisa tem como problema a ser analisado a presença feminina em cursos de graduação de engenharias. O objetivo geral é analisar as construções discursivas que limitaram os espaços de vivência das mulheres, causando diferenças sociais e de gênero, e especificamente, investigar a inserção feminina na Ciência e Tecnologia, e as principais dificuldades enfrentadas por elas. Para isso foram utilizados dados estatísticos veiculados pela Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) e do Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq); e, relatos de ex-alunas, ex-professoras, professoras, ex-professores e professores da Escola Politécnica da Paraíba, da Universidade Federal da Paraíba e da Universidade Federal de Campina Grande. Foram também utilizados artigos, dissertações de Mestrado e teses de Doutorado.

Authors: Siqueira José Flávio Rodrigues , Wiziack Suzete Rosana de Castro , Zanon Angela Maria
Published: March 2022

Apresentamos uma investigação qualitativa sobre as representações que professores da educação básica possuem sobre a escola como uma instituição sustentável. A coleta dos dados ocorreu por meio de um questionário aplicado junto a um grupo de 32 professores.  No tratamento desses dados foi utilizado o software IRaMuTeQ indicado para análise de conteúdo textual. Ancoramos a reflexão em teóricos da Educação Ambiental e na Teoria das Representações Sociais. Os resultados apontam que a escola sustentável é uma representação social presente entre os professores e está fortemente associada às ecotécnicas, que são propostas de alteração dos espaços físicos escolares visando uma melhor relação com o ambiente, mas também remete a uma prática educativa colaborativa, multidisciplinar e dialógica que possa reconfigurar o currículo, e à integração da escola à comunidade, por meio de uma gestão participativa e democrática.

The discovery of U mineralization in the late Variscan plagiogranite vein of the Shkhara crystalline massif (Greater Caucasus, Georgia)
Authors: Okrostsvaridze Avtandil , Bluashvili David , Gogoladze Salome , Gabrielashvili Rabi
Published: March 2022

The Greater Caucasus belt is the northernmost expression of the Caucasus orogen and is linked to the southern margin of the Precambrian Scythian Platform. In the pre-Jurassic crystalline basement of this belt, a plagiogranite vein, exposed in the headwaters of the Enguri River, with elevated radiation (μSv/h range of ~1–3), has been discovered. The vein is located along the Main Thrust of the Greater Caucasus, in the upper Paleozoic biotite migmatites of the Shkhara crystalline massif. It is ~2–3 m thick and represents hydrothermally altered rock (SiO2 content varies from ~75% to ~85%) predominantly composed of a quartz-plagioclase assemblage. LA-ICP-MS 206Pb/238U dating of zircons from the vein indicates an age of 310.2±7.5 Ma that corresponds to the late Variscan orogenic activity. The vein is slightly fragmented and fractured, and fractures and nests are filled with Th-enriched uraninite veins and impregnations. According to ICP-MS-ES analyses, the Th content varies from ~26 ppm to ~50 ppm, and the U varies between ~55 ppm and ~290 ppm. Based on the conducted research, it was found that there is a full correlation between the studied vein and U-bearing granitic veins of different regions of the world by composition, magma series, geodynamic setting, tectonic location and isotopic age. On this basis, it is supposed that the late Variscan hydrothermally altered plagiogranite veins, which are localized in the shear zones of the Shkhara Massif, and entirely in the Main Range Zone of the Greater Caucasus, are potentially U-bearing.

Results: All of daily workers heard about the virus. About 96.9% know the name of virus. About 80% of daily workers have awareness about major prevention measures and virus transmission ways. Ninety three percent believe that virus can affect themselves but 28.1% does not believe that hand shaking can transfer virus. Only 14.8% practice hand washing required to prevent corona virus transmission recommended by world health organization. About 73% believe that social distancing is important to prevent virus transmission but 94.8% of daily workers do not keep the WHO recommended distance when they talk or sit with their friends. Age above 40, Married and urban residentsbetter perform prevention activities such as hand washingand physical distancing compared to counter parts. Conclusion and recommendation: All of daily workers participated in this study heard about corona virus and most know its prevention methods. But the practice of hand washing and physical distancing is very low. Keywords: knowledge; attitude; practice; corona virus; COVID 19.

Since Coronavirus disease (COVID-19) was declared a pandemic on 3/12/2020 by the World Health Organization (WHO), diagnosed cases have continued to be on the rise worldwide, even though rates of new case detection seem to be stabilizing here in the United States [1]. This pandemic has impacted delivery of healthcare as well as health care workers in many aspects. In this article we discuss the impact of COVID-19 on cardiology fellowship training, early career concerns of fellows in training, and some suggestions to help training programs to cope with these challenges. It remains unclear how this pandemic will impact our health systems for the foreseeable future and thus a call to action is needed to reassess education needs and strategies of trainees during the pandemic not only in the interest of our FITs but also their future patients.

A 22 year old lady, who is a stage performer presented with a history of trauma to the forehead following a road traffic accident (Figure 1). The post traumatic image of her face was heartbreaking for her. Patient was taken for Plastic surgery procedure under general anaesthesia. Procedure was started using the principles of microdebridement, tissue undermining, tissue stretching and relaxation, extending the incision beyond the trauma along the Langer’s lines, layered suturing and preserving the anatomical landmarks like hairline and position of eyebrows. A trapezoid-shaped defect of size 10 cm transversely and 5 cm vertically was there after debridement (Figure 2). We could close the defect primarily without the need for skin grafting or did not leave residual raw areas for secondary healing. Finally, with patience after around 2.5 hours, we could achieve a result like this following the surgery (Figure 3). Close follow up and scar reduction measures like massage, creams and direct sunlight prevention for 1 year delivered us a good result.

Congenital dermal sinus tracts are an uncommon form of spinal dysraphism. If identified and treated early, outcomes are favourable. If missed, complications can be significant. Intramedullary spinal cord abscess is a rare but catastrophic complication. We report the case of an infantile patient with an intramedullary spinal cord abscess occurring 2-months post treatment for a coliform meningitis with an unidentified dermal sinus tract. We examined the literature on the investigation and management of dermal sinus tracts and conclude that all cases of unexplained, atypical meningitis in an infant should trigger suspicion for an underlying dermal sinus tract. In such cases, an MRI scan of the neuroaxis should be performed urgently. Keywords: syrinx; dimple; meningitis; dysraphism.

The corpus callosum is composed of 4 segments namely the rostrum, thegenu, the body and the selenium 20 weeks all of these components are expected to be present in the midline. It continues to grow in thickness and length and reaches maturity around the age of 9-10 months [1]. Agenesis of the Corpus Callosum (ACC) is a heterogeneous congenital neurodevelopmental disorder that can be seen in isolation or in combination with other brain abnormalities such as are Dandy walker Disease, Mega large cistern, vermal hypoplasia and Rathke’s pocket cyst [2]. Then, ACC is dysgenesis of the callosum which results in the complete or partial absence of its components. The MRI is the gold standard of Diagnosis, shows the frontal horns of the lateral ventricles which take a disposition having an aspect of the horns of bulls [1,3]. This typical appearance when present is pathognomonic for ACC as showing in Figures 1A and 1B.

Connatal cyst also known as frontal horn cysts, are cystic areas adjacent to the superolateral margins of the body and frontal horns of the lateral ventricles and are believed to represent a normal variant [1]. The other name is coarctation of the lateral ventricles or frontal horn cysts. Sometimes unilateral or bilateral, the incidence of this condition is between 0, 4 and 0, 9% [2]. Periventricular cysts are a common finding in neonatal cranial imaging. They are noted usually in antenatal period and typically disappear over the first year of the life [3]. The etiology has been debated varying from being a normal variant, to secondary to a viral infection, chromosomal anomaly, post-ischemic or hemorrhagic event [1,4]. They have been shown to regress on follow-up imaging when demonstrates in children under 2 months of age [3]. Our case demonstrates an exceptional situation of a persistent of the cyst in a 20-year-old -girl.

Background: There are not enough studies investigating the results of stent implantation for Coarctation of the Aorta (COA) in the pediatric age group. Objective: This investigation evaluated the heart function and remodeling after successful COA stenting in children. Materials and method: The study was performed from April 2017 till April 2020 on patients with COA (<18 years old) referring to Namazi, Faghihi and Kowsar hospital, tertiary centers from 2010 till 2017. Demographic data, clinical examination results and echocardiographic parameters were reported. All statistical analyses were performed with the SPSS version 22. Results: Fourty-two children were enrolled in this study. Mean age at the time of stenting was 10.44 ± 3.93, and mean follow-up was 3.57 ± 3.40 years (1-6 years). 24 patients (77.8%) were male. Measurement of thoracic aorta diameters revealed that mean transverse arch, isthmus and distal arch diameter with its z-scores were 1.40 ± 0.43 (Z score = -1.50 ± 1.33), 1.17 ± 0.28 (Z score =-0.72 ± 1.43) and 1.21 ± 0.42 (Z score = -0.94 ± 3.46). Mean systolic blood pressure at the follow-up time was 122.5 ± 17.70 mmHg, and mean diastolic blood pressure was 81.25 ± 9.57. Significant correlation existed between IVSd value and transverse arch diameter (P=0.023, r=0.564), and also distal arch diameter (P=0.039, r=0.521). There was also a significant correlation between LVIDd and measured transverse (P=0.007, r=0.648) and distal arch diameter (P=0.034, r=0.521). Instead, the correlation between E/A value and IVSs (P=0.023) and IVSs Z score (P=0.044, r=0.480) was significant. There was a significant correlation between LVPWd parameter and Doppler measurement of the gradient at the stent site (P=0.024, r=0.621) measured at the time of follow-up. Conclusion: Based on the results, endovascular stenting to treat CoA appears to be a safe and efficient method. LV hypertrophy and diastolic dysfunction did not regressin a significant number of patients after successful stenting. Keywords: aortic coarctation; child; heart; stents.

A pro-inflammatory response in patients with coronavirus disease provokes hypercoagulability and hyperviscosity, following an excessive liberation of acute phase reactants. Thromboembolic complications such as Deep Venous Thrombosis, Pulmonary Embolism, Stroke and Acute Coronary Syndrome were described from the beginning of the pandemic as possible manifestations of this new virus. Priapism is a medical urgency that demands quick assessment and timely treatment. A case of priapism is presented in a patient undergoing hospitalization for COVID-19. He was treated with cavernosal blood aspiration, irrigated with 0.90% w/v saline solution and intracavernosal injection of the sympathomimetic agent (adrenaline), with favorable response. Keywords: priapism; COVID-19; thrombosis.
