Preliminary project design for insect production: part 3 – sub-process types and reactors
Authors: Kok R.
Published: March 2021

This is a discussion about sub-processes suitable for the rearing of insect larvae on dry and semi-dry feeds. Three closely related, key aspects are dealt with as part of preliminary project design (PPD): the type of larval rearing sub-process to be employed, the reactor configuration and the operational approach to be used. A number of sub-process types and reactors are discussed. Because they are most commonly used in the industry today, all the sub-processes are ‘plug-flow’ (age stratified) and based on ‘passive’ reactors (contents moving through the reactor). Batch, semi-continuous as well as continuous sub-processes are dealt with and illustrated. Simulation to help the entopreneur chose the most appropriate type of sub-process is highly recommended.
Preliminary project design for insect production: part 4 – facility considerations
Authors: Kok R.
Published: March 2021

At the end of the preliminary project design (PPD) phase an aspiring entopreneur should have a clear idea of the scope and scale of the project being proposed. Hence, during PPD a number of aspects of the facilities must be considered. These are here dealt with in terms of basic questions that should first be answered about the project as a whole; project location issues; to what degree the facility is to be integrated or segregated into different units; what functionality is to be housed within the various building envelopes; and how safety and hygiene concerns can be addressed. As well, three ancillary issues are discussed that may affect facility design, construction and operation: the development of new production organisms that can grow on low-cost feeds; the possibility of disease evolution; and the matter of animal welfare.

Published: March 2021

The study focuses on the possibility of turning social media into an effective tool to improve digital literacy and facilitate cognition. In view of this, a one-month experiment involving 268 eighth graders from two Moscow schools was con-ducted; the participants were divided into a control and an experimental group. The students were encouraged to independently search and develop social net-work skills to solve educational issues and improve cognition. Objective perfor-mance tests were conducted based on the curriculum results. According to the ac-ademic performance, the mean grade on a 12-point scale in the experimental group increased from 7.77 to 8.76 points, while in the control group the change remained within the statistical error (7.64 and 7.76, respectively). A strong corre-lation between the grades obtained in different groups (0.8 when comparing the final results in two groups) was found. The study can be put into practice within the framework of the widespread introduction of social media in school curricula as a tool to access information, develop digital literacy and the ability to use digi-tal cognition tools being supervised and supported by a skillful teacher.

Published: March 2021

This study is devoted to the peculiarities of online education, namely, the use of virtual laboratories. The emphasis is being placed on the development of a laboratory model that can take advantage of the available online courses and adapt them for students with special educational needs. The research describes the learning process in a virtual laboratory, options for integrating online courses, and the ways of presenting them to students with certain educational needs. As a result, a virtual laboratory model was developed; it has been primarily designed for people with hearing and vision impairment, and musculoskeletal disorders. Thus, each user category was submitted several options for the educational process implementation within the virtual laboratory. The theoretical model allows creating a virtual laboratory to teach students with special educational needs. Based on the student experience of using the laboratory, research aimed at searching for new ways of presenting information and improving existing ones could be conducted.

Authors: Syzdykova Zhibek , Koblandin Kalybek , Mikhaylova Natalia , Akinina Olga
Published: March 2021

The e-portfolio development and introduction are based on the fact that the reflective practice of its creation allows students to document and track learning, develop a coherent picture of experience, and improve self-understanding. The study took place at Lomonosov Moscow State University (Russia); an assessment tool to design and develop electronic portfolios in the higher education system has been developed and tested in the study. A survey focused on the value of an electronic portfolio, which was positively assessed by the respondents, was conducted. The students participating in the study developed e-portfolios that described their reflections on the learning process and backed the arguments made with proof. The assessment showed that 60% of students should improve their cooperation skills while skills related to conceptualization and implementation, critical thinking and decision-making, assessment and modification, meta-cognition and progress should be developed in 44%, 33%, 52%, and 64% of students, respectively. The research results confirm that e-portfolios provide an appropriate platform for integrative learning that allows students to visualize the relationship between various concepts learned throughout the course and beyond.

Published: March 2021

The purpose of the study is to analyze the modern approach to the student performance assessment system and propose options for its improvement by automating the student result processing system. An experiment to analyze the implementation of an automated student result processing system based on the Power BI service developed by Microsoft and compare the results of the control and experimental groups was conducted at Sechenov University and the Capital University of Economics and Business. In total, 12 departments took part in the experiment (there were 6 departments that used the Power BI service and 6 departments that relied on the electronic university journal). The group that worked with Microsoft Power BI received visual results of student performance, which graphically displayed the dynamics. In turn, the group that created analytics with the help of the electronic university journal could not see most indicators of the student performance dynamics; in addition, it took 6 times more time to create such incomplete analytics compared to the analysis performed in the Power BI service. The practice of other educational institutions and organizations has shown that automation tools are being actively implemented at universities; however, the experience of using Microsoft Power BI in the educational environment is quite limited due to its recent introduction.
A Fuzzy Evaluation Model of College English Teaching Quality Based on Analytic Hierarchy Process
Authors: Li Nan
Published: March 2021

The evaluation of English teaching quality in colleges mainly faces two problems: the evaluation index system (EIS) is incomplete, and the evaluation model cannot easily handle complex fuzzy indices. To solve the problems, this paper explores deep into the fuzzy evaluation of college English teaching quality, and establishes a fuzzy evaluation model of college English teaching quality based on analytic hierarchy process (AHP). Firstly, theoretical analysis was combined with model calculation to create an improved multi-angle EIS for college English teaching quality. From both quantitative and qualitative analyses, a college English teaching quality evaluation model was constructed to handle fuzzy indices. Implementation results show that the proposed EIS and fuzzy evaluation model can effectively assess the quality of English teaching in colleges. The research results greatly promote the quality improvement of college English teaching.

Published: March 2021

O artigo analisa registros do Caderno da Realidade de estudantes finalistas do curso de Licenciatura em Educação do Campo (LEDOC) em busca de pistas e indícios das experiências de vida e formação por eles expressas. Fundamenta-se no conceito de experiência (Erfahrung) em Walter Benjamin (2016) e também na noção de autoconhecimento e auto-formação (JOSSO, 2004). Ao rastrear vestígios (GINZBURG, 2002, 2007) dos percursos de vida e de formação dos sujeitos evidenciados em suas falas/escritas, oportunizados pela Pedagogia da Alternância, o estudo aponta essas experiências como um terreno fértil para pensar as possibilidades formativas que inter-relacionam diferentes vivências em espaços que passam a ser vividos-pensados-sentidos como espaços formativos em interlocução.

Authors: Castro Liana Garcia , Falcão Barbosa Silvia Néli , Silveira Aline
Published: March 2021

Este texto é fruto de uma pesquisa interinstitucional que procurou identificar e compreender as marcas de cuidar e ser cuidado nas narrativas de crianças, seus professores e suas famílias, em creches, pré-escolas e escolas. Tem como objetivo apresentar entrevistas realizadas com famílias, discutindo suas compreensões sobre cuidado. Como metodologia, apresenta entrevistas individuais e coletivas realizadas com as famílias, tendo Martin Buber como principal interlocutor teórico. Nas análises, emerge o cuidado como proteção e vigilância, tempo de estar junto, presença, como algo que precisa ser compartilhado. Em tempos áridos e difíceis, pensar sobre cuidar e ser cuidado contribui para o reconhecimento da humanidade do outro como caminho possível para ir na contramão da barbárie.

Published: March 2021

The authors aim to explore the pattern and demographics of dermatological disorders occurring during Hajj 2019. Clinical records from three major public healthcare facilities in Al-Madinah Al-Munawara were retrieved for the period July-August, 2019. Collected data included age, gender, nationality, and dermatological complaints. 550 records were retrieved. Patients were 282 (51.3%) males and 268 (48.7%) females with a mean age of 58.3±12.6 years. Most patients were Asians (n=320, 58.2%), and Africans (n=183, 33.3%). Accidents (n=226, 41.1%), and infections (148, 26.9%) were the most common complaints. Asians and Africans had significantly: more accidents and less infections (P=0.002, P=0.027 respectively). They were the only category affected by exacerbations of auto immune diseases. Asian and African pilgrims are mainly affected by traumatic dermatologic conditions. Preventive awareness programs should target these ethnicities to reduce their higher rates of accidents. Other ethnicities need programs that promote hygienic practices and target infections.
Endoscopic removal of slow release oxycodone tablets in a case of voluntary acute poisoning
Authors: Serra Sossio , Geniere Nigra Stefano
Published: March 2021

We describe a case of 83-years-old women admitted to the Emergency Department after massive ingestion of slow release Oxycodone pills for suicidal purpose. After gastric lavage only few tablets has been retrieved and Naloxone infusion was necessary. After 2 hours from drug ingestion Esophagogastroduodenoscopy (EGDS) was performed and a number of tablets have been removed. Intoxication symptoms completely resolved and Naloxone infusion has been stopped. The clinical courses of this intoxication suggest that the utility of EGDS to remove tablets should be considered in selected cases of drug poisoning.

Published: March 2021

There is no information on coronavirus disease 2019 (COVID-19)-related outcomes for adult patients with congenital heart disease (ACHD). We aim to assess the clinical burden of COVID-19 on ACHD patients during the initial stages of the pandemic in Europe. ACHD patients followed in 2 tertiary centers in the Lombardy region were screened for COVID-19-related symptoms and complications. 661 patients (52.3% male, mean age 34.9±11.7 years) with CHD of moderate (58.5%) or high (32.8%) complexity were contacted. Of these, 145 (21.9%) reported typical COVID-19 symptoms, but only 4.8% required hospitalization. We did not record confirmed COVID-19-related deaths. Patients hospitalized were elderly (P=0.03), more likely to be receiving diuretics (P=0.03) or beta-blockers (P=0.02), and have been admitted over the previous year (P=0.003). Of the 7 patients hospitalized, 2 had a systemic RV and 2 a Fontan circulation. COVID-19-related morbidity and mortality have been low in ACHD patients 6 weeks from the start of the outbreak, in one of the worse hit European regions.

Authors: Yasri Sora , Wiwanitkit Viroj
Published: March 2021

Tuberculosis is an important public health problem that needs good control. The interrelationship between air pollution and incidence of tuberculosis is interesting. In the present report, the authors report the observation on tuberculosis incidence in area with sulfur dioxide pollution. The retrospective analysis on public available on incidence of tuberculosis and ambient air sulfur dioxide level in Thailand is done. There is no significant relationship between air sulfur dioxide level and corresponding incidence of tuberculosis (r = –0.224, P = 0.535). In conclusion, there is a lack of association between air sulfur dioxide level and corresponding incidence of tuberculosis in our setting.
Recent advances in the protective role of hydrogen sulfide in myocardial ischemia/reperfusion injury
Authors: Zhang Meng-Ling , Peng Wei , Ni Jian-Qiang , Chen Gang
Published: March 2021

Hydrogen sulfide (H2S) is recognized to be a novel mediator after carbon monoxide and nitric oxide in the organism. It can be produced in various mammalian tissues and exert many physiological effects in many systems including the cardiovascular system. A great amount of recent studies have demonstrated that endogenous H2S and exogenous H2S-releasing compounds (such as NaHS, Na2S, and GYY4137) provide protection in many cardiovascular diseases, such as ischemia/reperfusion injury, heart failure, cardiac hypertrophy, and atherosclerosis. In recent years, many mechanisms have been proposed and verified the protective role exhibited by H2S against myocardial ischemia/reperfusion injury, and this review is to demonstrate the protective role of exogenous and endogenous H2S on myocardial ischemia/reperfusion injury.
A universality law for sign correlations of eigenfunctions of differential operators
Authors: Gonçalves Felipe , Oliveira e Silva Diogo , Steinerberger Stefan
Published: March 2021

We establish a sign correlation universality law for sequences of functions

\{w_n\}_{n \in \mathbb{N}}

satisfying a trigonometric asymptotic law. Our results are inspired by the classical WKB asymptotic approximation for Sturm–Liouville operators, and in particular we obtain non-trivial sign correlations for eigenfunctions of generic Schrödinger operators (including the harmonic oscillator), as well as Laguerre and Chebyshev polynomials. Given two distinct points

x, y \in \mathbb{R}

, we ask how often do

w_n(x)

and

w_n(y)

have the same sign. Asymptotically, one would expect this to be true half the time, but this turns out to not always be the case. Under certain natural assumptions, we prove that, for all

x \neq y

,

\frac{1}{3} \leq \lim_{N \to \infty}{ \frac{1}{N} \# \{0 \leq n < N\colon \mathrm {sgn}(w_n(x)) = \mathrm {sgn}(w_n(y)) \}} \leq \frac{2}{3},

and that these bounds are optimal, and can be attained. Our methods extend to other problems of similar flavor and we also discuss a number of open problems.

Published: March 2021

Melon seed husk (MSH) biochar was used in a single cell direct carbon fuel cell (DCFC) as an alternative biofuel. The DCFCs belong to a generation of energy conversion devices that are characterised with higher efficiencies, lower emission of pollutants and MSH biochar as the fuel. Several analytical techniques (proximate, ultimate and thermo-chemical analysis) were employed to analyse the characteristics of the biomass fuel, their effects on the cell’s performance, and the electrochemical reactions between the fuel and the electrolyte in the system. High carbon content and calorific values are some of the parameters responsible for good performances. The performance of a lab-scale DCFC made of ceramic tubes using molten carbonate electrolyte was investigated. Binary carbonates mixture (Na2CO3-K2CO3, 38-62 mol.%) was used as electrolyte and the waste MSH carbonised at 450oC as biofuel. A practical evaluation of the fuel used in the DCFC system was conducted, for varying temperature of 100 - 800oC. The maximum open circuit voltage (OCV) was 0.71 V. With an applied load resistance and active surface area of 5.73 cm2 the maximum power density was 5.50 mWcm-2 and the current density was 29.67 mAcm-2 at 800oC.

Authors: Odame E. , Gonu H. , Quansah L.
Published: March 2021

Changes in climatic conditions are associated with changes in the physicochemical properties of many fruits. Four germplasms of cashew apple originating from Brazil, Tanzania, Ghana (herein referred to as local) and Mozambique but all grown in Ghana were studied to assess the effect of agro-climatic zones on the sugar accumulation, pH, and weight of these cashew apples. Cashew apples were sourced from experimental stations in Bole and Wenchi in the Northern and Savannah regions of Ghana, respectively. A total of 1800 fruits were used for the experiment. Inter and intra significant differences (P < 0.05) were scored amongst ger­mplasms collected from both locations concerning the measured parameters. Sugar ranged between 8.7% - 12.5% with fruits from Bole having the highest sugar content. The pH value ranged from 3.9 (Local germplasm from Bole) – 4.3 (Tanzania germplasm from both loca­tions). The weight ranged between 33 g (Tanzania germplasm from Bole) – 69.8 g (Brazil germplasm from Bole). Meteorological data (from February 2017- April 2018) collected from both locations inf‍luenced the parameters, thus associating with the fruits from both locations. Conclusively, the present study indicated that, weather and geographical locations had an effect on sugar content, pH, and weight of cashew apples.

Authors: Michael Popoola Omoniyi , Olubunmi Olagunju Oluwatosin
Published: March 2021

AbstractIntraspecific morphological variation in Clarias gariepinus was studied in three water bodies. Twenty-three morphometric characteristics and seven meristic were used. Principal component (PC) analysis showed that morphometric traits of River Osun and Ogbese were somewhat related while that of Aago showed no relatedness, there were no difference among the meristic counts of the populations. PC1, and PC2 accounted for 93% and 4% of the variation observed in the populations. High positive correlation was observed in Aago (r = 0.872, b = 2.10) and Ogbese population while low correlation and negative allometric growth (r = 0.425 and b= 1.38) was observed in Asejire population. Cluster analysis revealed that three studied populations are separated into two major clusters, with samples from Asejire and Ogbese population found within the same cluster but different sub- clusters, similarly some of samples from Aago were also within the same cluster while samples 10 were found on a separate and major cluster. The study confirms the variability among individual species within each population, indicates the presence of genetic diversity among the populations of C. gariepinus and the Pre-anal distance and dorsal fin ray count could be employed in the identification of populations of catfish.

Computational design and static-structural analysis of a small-scale turbojet propulsive engine for an unmanned aerial vehicle
Authors: Effiom Samuel O. , Abam Fidelis I. , Saeed Burhan , Ochedi Sunday O. , Evareh John E.
Published: March 2021

This study focused on the computational design and static structural analysis of a small-scale turbojet engine (SSTE) that can power an unmanned aerial vehicle with a thrust of 50 N at a speed of 8000 rpm. SOLIDWORKS 2018 was used to design the CAD geometry of the SSTE, and to carry out a CFD analysis on the compressor to determine the pressure distribution across the compressor and the compressor pressure ratio. The obtained pressure ratio was further used to carry out a structural analysis of the SSTE with emphasis on the turbine component using ANSYS static structural module. This analysis was done to determine the level of deformation of the chosen design material (stainless steel grade 310), the maximum and minimum stresses, factor of safety, and its fatigue life. Design and CFD results obtained shows that the design as well as the pressure distribution in the compressor is reliable. The 50N small scale turbojet engine showed higher optimum performance from structural design and evaluation when compared to that of the 70N thrust jet cat model. Results of the structural analysis shows that the turbine blades will experience minimum and maximum deformation of 0 m and 2.2543×10−5 m at the leading edges and trailing edges of the blade chord respectively. Also, maximum and minimumstresses will occur at 1.0632×105 Pa and 6.7192×107 Pa respectively. Conversely, the factor of safety was within 3.0807 to 15 which show that the design is adequate. Additionally, considering the fatigue life, the SSTE is bound to fail completely at approximately 1.929×107 months. Therefore, the SSTE with the materials suggested above is capable ofpropelling an unmanned aerial vehicle considering the results obtained.

Water Scarcity and Food Security in Ngqeleni Locality in the Eastern Cape Province- South Africa
Authors: Amoah Laura Novienyo Abla
Published: March 2021

South Africa in general and the Eastern Cape Province in particular face increasing water shortages. However, little empirical evidence exists on how rural households are affected by water scarcity and the impact thereof on food security. This paper discusses the relationship between water scarcity and food security in Ngqeleni, a rural location in Eastern Cape, South Africa. Through empirical evidence collected using techniques inspired by the tradition of participatory focus group research and self-administered questionnaires in Ngqeleni, it is argued that there is a significant relationship between water scarcity and food security. Results also reveal that population growth, lack of political will and commitment, inadequate water resource infrastructure, and weaknesses within the institutional framework are some of the causes of water scarcity. Until effective water management systems are identified and enforced, food security will continue to plague Ngqeleni.

Authors: Hemmonsbey Janice , Tichaawa Tembi , Knott Brendon
Published: March 2021

This study aimed to identify the practical and policy-based implications for the South African sport tourism organisations by highlighting strategic approaches to rethinking sport tourism planning and management. A content analysis of published academic and industry papers that focused on disaster management or mitigation within the sport tourism context, within a global and local context were analysed and thematically coded. The results reveal the vulnerability of the sport tourism industry to global threats while highlighting the lack of preparedness of this sector to strategically respond to the COVID-19 pandemic. Previous pandemics and disasters may provide an impetus for rethinking sport event hosting as well as travel and tourism, however not without substantial financial investments and government support. The resilient theory emphasises the synergistic effects of crisis management in sport tourism. This study proposes strategies to guide industry stakeholders towards a research agenda that is based on identified gaps in knowledge within the sport tourism field in order to rethink sport tourism. This paper also contributes to the extant knowledge on crisis management and disaster management by incorporating strategic perspectives of resilient theory. There is significant value to current policies and practices regarding new strategic approaches to crisis management in sport tourism

Authors: Moagi Thato Joseph , Ivanovic Milena , Adinolfi Maisa
Published: March 2021

Soweto is South Africa’s most iconic tourist destination, providing local street vendors with an opportunity to sell arts and crafts. This paper presents a detailed overview of business challenges faced by a population of 60 arts and crafts street vendors operating at two main tourist attractions in Soweto, the Mandela House/Museum and the Hector Pieterson Memorial. The study employs a mixed methodology based on a four-stage exploratory sequential research design. The profile characteristics of arts and craft street vendors lead to some interesting conclusions whereby the triangulation of qualitative and quantitative results reveals the main challenges in operating their businesses. They are grouped as: a) inadequate infrastructure, especially a lack of dedicated trading space and storage facilities; b) lack of safety due to high levels of congestion and crime affecting daily trade; and c) non-compliance with legislation, lack of government funding and reliance on the cash economy. The study presents a contribution to tourism literature on the little-known challenges of informal businesses trading as arts and crafts street vendors at main tourist attractions in Soweto.
Tourism and Local Economic Development in King Sabata Dalindyebo Local Municipality, South Africa: Stakeholder Perspectives
Authors: Dlomo Thobeka , Rogerson Christian
Published: March 2021

Over the past two decades a major burst of scholarship has occurred around tourism and local economic development futures in South Africa. This study addressed the question of key stakeholder perceptions of local economic development through tourism as the economic driver. In addition, it examines the challenges for enhancing the local development role of the tourism sector. Arguably, stakeholders at the coalface of tourism and local development issues, such as tourism business owners and local government officials, can offer useful insights into the everyday problems of maximizing the impact of tourism in local municipalities. The focus is on the King Sabata Dalindyebo Local Municipality (KSDM) in Eastern Cape province. The results are presented and dissected from 33 interviews conducted with private sector stakeholders as well as 20 government stakeholders. Stakeholder perceptions were investigated concerning three major themes: (1) the role and prospects for tourism and local economic development, (2) the use of municipal assets for tourism development; and, (3) the challenges facing tourism businesses for local economic development The research findings underscore several factors that explain the decline of the tourism economy of KSDM since 2006 and reduced its contribution to local economic development. Central issues surround crime and safety, infrastructural deficiencies, and shortcomings of the local government itself, including its failure to maintain critical municipal assets essential for tourism development.
A Global Perspective on the COVID 19 Crisis and an Ontological Theology Perspective
Authors: Henderson Erwin Samuel
Published: March 2021

This article asks whether human history has any bearing on understanding and interpreting the Covid 19 pandemic. It seeks to examine the historical and present circumstance to identify possible causes, dangers, responses and solutions. It more importantly seeks to respond to the question, is there a possible conjuncture with an ontological theology view of God and the world? The aim of the first section is to present a succinct overview of pandemic themes and in the second, to articulate three significant responses from the ontological theology perspective. This view has for primary focus the reality of the Person of God with emphasis on being and existence, both His and ours in general and specifically in times of crisis. Where is God? Why is this happening? What is He saying? Why does He not intervene? Crises evoke fundamental belief questions. The article therefore, seeks to demonstrate the validity of a cohesive connection between the divine, transcendent and eternal with humanity and human history.

The entity by which something is produced specifically is known as Nidana. It is Adikarana- means to prime factor among diverse determinants of disease. Illness is because of different causes and its effect is seen in the form of linga-symptoms of a disease. Because of which ancient seers propounded the Trisutra Ayurveda, namely hetu-linga and Aushadha. In many contexts of Samhitha, while Nidana engendering Vyadhi, Guna- properties are described, because properties have considerable importance in pharmacologi-cal, pathological action. One such context is Kushta Nidana, where aetiology delineated as Sheetoshna Vyatyasa - interchange use of cold and hot properties. This article foregrounded on the proposition of Kar-ya-Karana-Vada of Ayurveda, to throw light on the expository of Gunas in manifesting Kushta.

In Ayurveda there are two folds of treatment one is Shodhana and the other is Shamana. Shodhana in-cludes panchakarma which is used to purify the body by removing the vitiated doshas of body. All five Panchakarma procedures act specifically on specific doshas. Sneha nasya i.e. administration of medicated oil through nasal cavities is one of the Panchakarma procedure which specifically used to treat Urdhva Jatrugata Vyadhis. According to Ayurveda, nose is the gateway of Shiras –brain , it can provide direct connection between brain and nasal mucosa and can transfer the administrated medicines from nose direct-ly to cranial cavity. This is why Nasya karma is used to treat diseases of head region which are generated by vitiated Kapha and Vata dosha. Medicated Sneha has lipid soluble substances which gets easily ab-sorbed by mucous membrane of nasal cavity and get easily transmitted to cranial cavity. The anatomical connectivity of nose with cranial cavity has been proved by modern science also. The direct nerve supply from CNS and the rich vascular supply to nasal cavity help to understand probable mode of action of Nasya Karma.

Pregnancy is a phenomenal and remarkable time in any woman’s life which requires added care and attention. Pregnancy is a sensitive state where the woman is more susceptible for infections. Amidst the Global Pandemic of Covid-19 special awareness and protection is of considerable necessity. In this view, Ayurveda being the Traditional Indian Medicine plays a crucial role in safeguarding the mother along with the growing fetus. Classical reference gives emphasis to the use of herbal drugs (Garbhasthapaka dravyas) which possess Anti-oxidant and Immuno-modulator properties. Ayurveda also provides the evidence of Ahara, Vihara, Aushada & Sadvritta which is imperative in every pregnant women. In this phase, as the body demands extra nutrition for the developing fetus the periodic dietetic regimens quoted help deliver a child possessing good health, energy and strength. Besides this, Yoga is one unique technique (gentle movements and slow breathing methods) which is safe and effective during pregnancy. Hence an effort is made to understand systematic preventive measures of Ayurveda in pregnancy through this Pandemic.

Marble is globally used as a natural stone for decorative and architectural purposes. Primary utilization of marble is as building and dimension stones. Mechanical properties and aesthetic aspects are major characteristics of marble and decisive factors for its selection and utilization. It is therefore imperative to evaluate the key strength properties i.e. Uniaxial Compressive Strength (UCS) and Uniaxial Tensile Strength (UTS) of marble before its utilization. These key strength parameters are dependent on textural features of marble. Present study investigates the effect of two key textural features i.e. grain size and grain shape on two key strength parameters i.e. UCS and UTS of marble samples taken from three different regions i.e. Buner, Chitral and Swat in the north western part of Khyber Pakhtunkhwa. Correlation and regression analysis between these textural properties and strength parameters revealed that prominent textural features of grain size and shape can be used as a quick indicator for assessment of strength parameters and as guideline for appropriate utilization of marble.

Landslide is a frequently occurring natural calamity in the northern areas of Pakistan. The current study is aimed to assess the susceptibility of landslide hazard to highlight the vulnerable areas for the purpose of risk reduction along Neelum and Jehlum rivers in district Muzaffarabad. A data-driven predictive approach was adopted to conduct this study by using Weight of Evidence (WOE) model along with eleven conditioning factors. A spatial distribution map of landslides was prepared using orthophoto, previous records, and derivatives (hill shad, topographic openness, slope, aspect, curvature) of Digital Elevation Model (DEM). The results show that the roads, lithology, and rivers are the most important triggering factors for landslides in both valleys. Approximately 30% of the area is under low susceptibility zone in Jhelum valley while only 13% of the area falls under low susceptibility zone in Neelum river valley. In Jhelum river valley the medium susceptibility zone covers 35% of the total area whereas, Neelam river valley has 26% of the total area under medium susceptibility zone. Around 61% of the land in the Neelam river valley and 35% of the land in the Jhelum river valley are under high susceptibility zone. The area under high hazard lies in the north-east of the district due to multiple conducive factors to trigger landslides including weak lithology (mudstone, sandstone, shales, and clays), high altitude along steep slopes and excessive precipitation (1800 mm/ year). Furthermore, the high hazard zone in study area is not suitable for construction purpose but was suitable for plantation. The validation result (89.41%) is justifying the performance of this model.
Cruelty or Humanity
Authors: Rees Stuart
Published: March 2021

Cruelty has long been a feature of states' domestic and foreign policies but is seldom acknowledged. Governments mouth respect for human rights yet promote discrimination, violence and suppression of critics. Documenting case studies from around the world, distinguished academic and human rights activist Stuart Rees exposes politicians' cruel motives and the resulting outcomes. Using his first-hand observations and insights from international poets, he argues for courageous action to support non-violence in every aspect of public and private life for the survival of people, animals and the planet.
On the Conditions for the Embedding of Classes of Almost Periodic Functions by Besicovitch
Authors: Хасанов Ю.Х.
Published: March 2021

В работе установлен ряд условий вложения классов
$B_q$-почти-периодических функций в классы $B_p$-почти-периодических
в смысле Безиковича функций с произвольными показателями Фурье при
$1\leq p<q<\infty$. Некоторые из этих условий являются аналогом
известных результатов других авторов о вложении классов $L_p$
$(1\leq p<\infty)$ периодических функций. В качестве структурной
характеристики таких функций используется модуль гладкости высшего
порядка с наперед заданным шагом. Так как пространство
почти-периодических функций Безиковича является полным нормированным
пространством, то в качестве полиномов наилучшего приближения
используются полиномы Бохнера~--- Фейера. Также в работе найдены
условия принадлежности функций Безиковича к~классу целых функций
ограниченной степени. Установлено, что если
$B_p$-почти-периодическая функция имеет величину наилучшего
приближения целыми функциями ограниченной степени, то для этой
функции существует абсолютно непрерывная производная, которая также
является $B_p$-почти-периодической.
Analyzing Flying Chameleons: Using Autoethnography to Explore Change in the Female Educator
Authors: Pourreau Leslie
Published: March 2021

What is a chameleon in the world of education? What defines her professionally, personally, and why? In this autoethnography, I explore the chameleon metaphor for meanings and implications in my personal and professional identity as a female educator by seeking answers to questions stemming from Mitchell and Weber (2005): Just who do I think I am? Just who do I think I am? Just who do I think I am? Just who do I think I am? I analyzed my own autobiographical journals using the four-part Listening Guide (Gilligan, Spencer, Weinberg, & Bertsch, 2003) coupled with theme-based family coding to examine changes by choice and changes by force particular to my personal and professional experiences. Notions of home, belonging, and change as a journey emerged as themes that served to frame my identity and highlighted the importance of self-inquiry for educators as an applied practice within the greater context of the profession.
Connecting the Dots: A Review of Traversing the Uncharted Arena of Computer Assisted Qualitative Data Analysis Software: Mapping Out QDA Miner 4.1 as a First-Time User
Authors: Cuva Andrea
Published: March 2021

A review of QDA Miner 4.1, a mixed method computer assisted data analysis software (CAQDAS), was conducted to determine how accommodating (if at all) the software was for beginning researchers and/or individuals less proficient with computers. Rather than maintaining the more traditional focus on the technical functionality of QDA Miner, this review was structured around the needs and interests of a beginning researcher. Although QDA Miner offers a variety of helpful resources, questions regarding how to structure initial project to ensure findings yield methodological accuracy remain.
Constructing Grammar Instruction in the Omani ELT System: A Critical Literacy Perspective
Authors: Al-Issa Ali
Published: March 2021

Debate in the literature has been ongoing about whether to teach English language grammar explicitly, implicitly or integrate both approaches to achieve optimal learning. This research paper, hence, discusses this issue from an ideological perspective with a particular reference to the Omani English language teaching (ELT) education system. The paper triangulates data from various semi-structured interviews made with different agents involved in the Omani ELT education system, the pertinent literature, The Philosophy and Guidelines for the Omani English Language School Curriculum, which I will herewith refer to as the National English Language Policy/Plan (NELP), other policy texts and the English language national syllabus – Our World Through English (OWTE) Teacher’s Guide. The critical discussion revealed various contesting ideologies about teaching grammar in the Omani ELT system and the crucial role of teachers in the effective policy implementation or otherwise. The study has important implications for other similar contexts around the world.
Experience of Being an Insider and an Outsider during a Qualitative Study with Men Who Have Experienced Significant Weight Loss
Authors: Moore Darren
Published: March 2021

The major question being answered in the study is, “What is the experience of being an insider/outsider in a study regarding men and significant weight loss?” The purpose of the paper is to explore the experience of being both an insider and an outsider, and specifically to discuss how researcher status and self-disclosure emerged and impacted the research process. The methodology used in the research study is narrative inquiry, specifically self-narrative. In the study, membership role status was found to be difficult to define, inherently complex, and arbitrary at times. Additional research on the topic of membership role status is needed and the level of importance should be further explored for the specific population.
"I'll Just Do My Time": The Role of Motivation in the Rejection of the DWI Court Model
Authors: Eckberg Deborah , Jones David
Published: March 2021

In the last decade, driving while intoxicated (DWI) courts based on the therapeutic court model have proliferated. Although the typical DWI court program allows offenders with multiple DWI offenses to avoid jail time and get their drivers’ licenses back sooner, not all offenders who are offered the opportunity to participate in DWI court choose to take advantage of it. Others try but drop out of the program early on. We conducted qualitative interviews with twelve people who were offered the opportunity to participate in an urban DWI court in a Midwestern county between 2007 and 2010, but who either chose not to participate or who tried but did not succeed in the program. The authors point to the relationship between intrinsic and extrinsic motivation in order to explain the findings and ultimately inform practitioner methods for engaging potential DWI court clients and enhancing success rates.
