Individual and Synergistic Anti-obesity Effect of Flax Seeds (Linum usitatissimum), Fenugreek Seeds (Trigonella foenum) and Black Seeds (Nigella sativa), in-vivo in Drosophila melanogaster
Authors: Thilagavathy Adikeshavan , G Singh Kavitha , Lobo Melantha Janet , Mayuri Mayuri
Published: November 2021

Obesity poses a major threat to global health, challenging the prevention of chronic diseases and health across the world. As synthetic
medicines have their side effects, lately, there has been an inclination towards herbal remedies. The present study was conducted to
evaluate the individual and syngeristic effect of Linum usitatissimum (flax seeds), Trigonella foenum graecum (fenugreek seeds) and
Nigella sativa (black seeds) on obesity. In-vivo studies were performed in Drosophila as many tissues and organs related to obesity
and its associated disorders are analogous in Drosophila and humans. Obesity was induced by supplementing lipid and high
concentration of glucose in the media. The effect of the seeds on obesity was studied by quantitative estimation of lipid content and
carbohydrate content in the larvae grown in different media preparations and also by assessment of physical activity of the flies. The
study revealed the efficient ability of the seeds to reduce obesity, synergistically as well as individually proving it to be a potential
strategy to combat the obesity naturally.

Published: November 2021

According to reports of ReAct forum, every year more than 750,000 patients die due to bacterial infections, making bacterial infection
one of the leading causes of disease infestation in an individual. Haemophilus influenzae disease, pneumonia and urinary tract
infections make the top of this list. Haemophilus influenzae is a gram-negative, commensal, facultative bacterium, which can mostly
cause pneumonia along with other diseases including bloodstream infections and arthritis. Though vaccine exists for Hib infections,
during infections of Hib and NThi the patients are administered antibiotics to treat the disease. Staphylococcus aureus is a grampositive versatile bacterium of the micrococcaceae family and one of the most dangerous pathogen-affecting humans as it can cause
pneumonia. Pneumonia is an acute pulmonary infection, which is associated with high mortality having a more pronounced effect on
young children. Urinary Tract Infection is a prevalent public health problem that is more common in women than in men. Though it
can be treated by appropriate antibiotics, due to recurrent infections, they lead to a gain of resistance. Thousands of research are
going on around the world to come up with a potential drug that can cure the Hi disease, Staphylococcus aureus related pneumonia
and UTIs entirely with the least drawbacks. In this study, we present a docking-based screening using a quantum mechanical scoring
of a library built from approved drugs and compounds, Amoxicillin and Cefuroxime with proteins with PDB ids 3CKM, 3EMF, 3ZU0,
4MV9, 5KCN, 5VBG, and 6XXY for Hi disease, 4RBR, 4MVN, 3KOR and 2RKZ for Staphylococcus aureus related pneumonia and 6QVX,
2F00, 6AYI and 2ID0 for UTIs could display antibacterial activity against the respective bacterial infections. This study needs to be
evaluated and further confirmed through experimental assays and clinical trials to validate the predicted results. This finding aims to
provide a better understanding and contribute

Natural bioactive compounds of Marine origin have attracted the attention of many biologists and chemists in the world over for the
last five decades because it has proven to be a rich source of structurally diverse and complex compounds exhibiting numerous
interesting biological functions. At present, many research findings have provided insight into biological activities of marine natural
compounds such as antioxidant- and anti-cholinesterase activity and neuroprotective effects on neurodegenerative diseases, viz.
Alzheimer’s and Parkinson’s. The main pathological hallmarks of AD is the formation senile plaques, neurofibrillary tangles and the
most incredible physiological and biochemical changes are reduction in acetylcholine (ACh) levels in the hippocampus and cortex of
the brain and loss of memory, decaying language etc. Present study is focused on to enhance the acetylcholine levels and
subsequently to prevent the formation of Senile Plaques and Neuro Fibrillary Tangles in tau protein responsible for Alzheimer’s
disease by using natural bioactive compound Squalene. Computational Biology and Bio-informatics have the potential not only to
speed up the drug discovery process but reduces the costs. Further, they also change the way drugs are designed by using Docking

An Investigation into Contract Cheating in Tertiary Education, and How to Combat the Problem in a United Arab Emirates Context
Authors: Pacino Andy
Published: November 2021

This review article investigated the pervasive problem that contract cheating presents in higher education in the United Arab Emirates (UAE), and aimed to discover whether a solution could be found to combat the growing use of essay mills among students in the region. This literature review aimed to answer the following research questions; why do students use essay mills? Is current university student academic support adequate to facilitate branch campus learning at a level equivalent to a home campus? What methods can international branch campuses in the UAE employ to discourage the use of essay mills? What type and levels of services can universities provide in the future that better support students and stop them from becoming potential essay mill users?  The point of the research was to find a means by which students can be dissuaded from using contract cheating sites by becoming so well-supported, and so aware of the threat that contract cheating poses to the value of their degree, that essay mills become a much less attractive option. The study began with a look into the possible circumstances that lead a student to cheat, which includes exploring the fraud triangle theory, the peer behaviour theory, the planned behaviour theory, and the subsequent methodology used. The study found a variety of reasons students cheat, citing laziness, a lack of ability or adequate depth of academic vocabulary in a second language learner, peer pressure, that it is so easy and convenient to use such sites, and the fact that there is a promise of plagiarism free work with a click of a mouse and simple financial transaction (Clarke & Lancaster, 2013). Furthermore, online contract cheating presents a significant challenge for higher education institutes to keep a check on standards and quality assurance. Many teachers are either unaware of or simply afraid to follow up on instances of contract cheating for fear of recriminations in the form of poor feedback or possible student dropout rates.

Authors: Ahmed Saifuddin , RAHMAN MD. ZARIF , Meem Mahabuba Islam
Published: November 2021

Purpose: The main objective of this study is to evaluate whether the COVID-19 pandemic has influenced the people of Bangladesh to become more fatalistic or not.
Approach/Methodology/Design: The study is of a descriptive design. The study follows a mixed-method research approach where an online survey was conducted among 406 individuals and 15 interviews of experts in different criteria have been assembled to validate the survey results properly. This survey data were analyzed based on the age and economic condition of the respondents. The in-depth interviews were collected based on six categories: Academicians, religious scholars, medical practitioners, Coronavirus-infected individuals, law enforcement officials, and journalists.
Findings: The study shows that most of the people of Bangladesh are not influenced by the fatalistic views. The COVID-19 pandemic has certainly made people more dependent on fate lately. Senior citizens of the society and people with low income are more fatalists than other groups of people in the society. Senior citizens are suffering the most from anxiety, youths of Bangladesh are facing the most uncertainty in this pandemic. None of the population groups are completely dependent on fate yet confident about the situation at the same time.
Practical Implications: The findings of this study will pave the way forward for further research in this area and help policymakers to take necessary initiatives. In short term, it will help formulating policies for the vulnerable groups. Such as, providing economic assistance for the lowest range of income group, guaranteeing old age pension for the senior citizens, access to right information, and psychological stability. In long term, this study will allow practitioners to create awareness during disasters and pandemics through expert narratives, news, and social media awareness.  
Originality/value: This paper explores how the belief system of people is influenced by their socio-economic condition and how it affects their behavior in terms of combating pandemics. It also emphasizes that during disasters and pandemics, policymakers should take special initiatives for senior citizens and people with low income.

Authors: Ogoun Ogoun
Published: November 2021

Purpose: This aims at analyzing the implications of covid-19 on the shipping/oil tanker market.

Methodology: In order to attain the aim of this study, findings and data are curated from existing literatures, documents, policies, etc. This implies that desk review is the methodology applied in this study where the researcher made use of secondary sources of data as against primary source of data.

Findings: In the study, it was found that covid-19 brought about a shortage in the rate of demands for good thereby causing an unbalance in the rate of supply over demand at a time which directly brought about a huge decline in shipping/oil tanker transportation. The study also found that irrespective of the huge decline in the rate of shipping/oil tanker transportation brought about by low demand in comparison with supply; shipping/oil tanker was patronized by dealers for the purpose of storage of products. Also, the study found that seaborne trade fell downward from above 3% to below a negative 8% and at a bdp rate of 100m, the demand was 3% higher than the global supply which in 2019 was at about 97%. However, in the second quarter of 2020 the supply leads demand at over 28M bdp and a 13% increase in the demand year-on-year when compared to a fall of 3.9% in the supply year-on-year.

Recommendation: The study recommends that appropriate forecasting methods and proper liaison with global health will aid in averting or ameliorating the risks and negative impacts brought on shipping/oil tanker market by covid-19.
Abstraction Logic
Authors: Obua Steven
Published: November 2021

Abstraction Logic is introduced as a foundation for Practical Types and Practal. It combines the simplicity of ﬁrst-order logic with direct support for variable binding constants called abstractions. It also allows free variables to depend on parameters, which means that ﬁrst-order axiom schemata can be encoded as simple axioms. Conceptually abstraction logic is situated between ﬁrst-order logic and second-order logic. It is sound with respect to an intuitive and simple algebraic semantics. Completeness holds for both intuitionistic and classical abstraction logic, and all abstraction logics in between and beyond.

La vaccinazione rappresenta uno degli interventi più efficaci e sicuri a disposizione della Sanità Pubblica per la prevenzione primaria delle malattie infettive]. Questa pratica comporta benefici non solo per un effetto diretto sui soggetti vaccinati ma – con il raggiungimento di elevate coperture vaccinali – anche in modo indiretto riducendo la circolazione di patogeni e inducendo la protezione di soggetti non vaccinati (herd immunity). Numerose evidenze dimostrano, infatti, che la vaccinazione è uno degli interventi sanitari di maggior successo e con il miglior rapporto costo/efficacia. In Italia i dati di copertura vaccinale del personale sanitario non sono raccolti routinariamente; studi ad hoc mostrano tassi molto bassi sia durante le stagioni epidemiche che in corso di pandemia. A differenza di quanto si è portato a pensare, gli operatori sanitari, per la loro scarsa propensione a sottoporsi ai vaccini, sono un anello debole ampiamente documentato nella catena di trasmissione delle malattie infettive. I tassi di vaccinazione oscillano da un anno all’altro in relazione ai falsi allarmi riportati dalla cronaca, esattamente come accade nella popolazione generale. Al fine di implementare interventi di promozione della vaccinazione, determinare la copertura vaccinale degli operatori sanitari, le loro caratteristiche anagrafiche e professionali in relazione allo stato vaccinale, la comparsa di eventi avversi, l'efficacia sul campo del vaccino e i motivi della vaccinazione/non vaccinazione, è stato condotto dall’UOC del Programma Infradipartimentale di Igiene Ospedaliera ed Epidemiologia dell’AOU San Giovanni di Dio e Ruggi d’Aragona “Scuola Medica Salernitana” uno studio trasversale di prevalenza tramite somministrazione di un questionario standardizzato e pretestato nel contesto dell’AOU.

Las normas, cuanto más ajustadas a la realidad social, son (y también se perciben como) más justas. En la situación actual, por la dureza de las circunstancias y los medios con los que se cuenta, es fácilmente comprensible que las demandas y las expectativas de la ciudadanía en lo tocante a los sistemas fiscales y su buena administración sean crecientes. Además, la aspiración a la justicia tributaria ha de acompañarse de una mayor eficacia y eficiencia en el gasto público -ya que materialmente ha de legitimar las nuevas exigencias-, en especial tras haber entrado en la última Década de acción para el logro de los objetivos de la Agenda 2030 de la Organización de las Naciones Unidas, que orienta no sólo la política fiscal europea sino también la mundial.

Apresentamos, aqui, os frutos de um trabalho realizado em sala de aula, durante uma disciplina da pós-graduação que tinha, como tema principal, as controvérsias científicas e sociocientíficas. O objetivo deste estudo foi levantar as percepções dos alunos (professores de ciências e matemática da educação básica) sobre polêmica e controvérsia antes e depois de uma disciplina ministrada em um programa de pós-graduação em educação e ciência e tecnologia no Rio de Janeiro. A diferenciação entre os termos é a proposta de um dos autores utilizados como referência para o curso, com o objetivo de contribuir para o aprofundamento dos debates a respeito do tema. O levantamento foi realizado em dois momentos: no início e depois do término da disciplina, por meio de dois instrumentos/materiais online bem semelhantes. Apresentam-se, aqui, as respostas das duas primeiras perguntas dos dois. Entre os achados, destaca-se que os participantes diferenciaram os dois conceitos, o que não costuma acontecer com frequência na literatura da área, estabeleceram, em um primeiro momento, relações de hierarquia entre um e outro. As controvérsias fazem parte do que se costuma denominar natureza da ciência e têm um papel importante no ensino de ciências, na prática dos professores, na sociedade, na educação cidadã. Atualmente, saber identificar uma controvérsia legítima e seus elementos constitutivos, além de ensinar outros a fazê-lo pode ser uma saída para combater movimentos negacionistas.

A fully automated, self-driving car can perceive its environment, determine the optimal route, and drive unaided by human intervention for the entire journey. Connected autonomous vehicles (CAVs) have the potential to drastically reduce accidents, travel time, and the environmental impact of road travel. Such technology includes the use of several sensors, various algorithms, interconnected network connections, and multiple auxiliary systems. CAVs have been subjected to attacks by malicious users to gain/deny control of one or more of its various systems. Data security and data privacy is one such area of CAVs that has been targeted via different types of attacks. The scope of this study is to present a good background knowledge of issues pertaining to different attacks in the context of data security and privacy, as well present a detailed review and analysis of eight very recent studies on the broad topic of security and privacy related attacks. Methodologies including Blockchain, Named Data Networking, Intrusion Detection System, Cognitive Engine, Adversarial Objects, and others have been investigated in the literature and problem- and context-specific models have been proposed by their respective authors.
Information Retrieval based on Cluster Analysis Approach
Authors: Almanaseer Orabe
Published: November 2021

The huge volume of text documents available on the internet has made it difficult to find valuable information for specific users. In fact, the need for efficient applications to extract interested knowledge from textual documents is vitally important. This paper addresses the problem of responding to user queries by fetching the most relevant documents from a clustered set of documents. For this purpose, a cluster-based information retrieval framework was proposed in this paper, in order to design and develop a system for analysing and extracting useful patterns from text documents. In this approach, a preprocessing step is first performed to find frequent and high-utility patterns in the data set. Then a Vector Space Model (VSM) is performed to represent the dataset. The system was implemented through two main phases. In phase 1, the clustering analysis process is designed and implemented to group documents into several clusters, while in phase 2, an information retrieval process was implemented to rank clusters according to the user queries in order to retrieve the relevant documents from specific clusters deemed relevant to the query. Then the results are evaluated according to evaluation criteria. Recall and Precision (P@5, P@10) of the retrieved results. P@5 was 0.660 and P@10 was 0.655.

BACKGROUND:

Fibromyalgia syndrome (FM) is a systemic disease of unknown etiology, which can cause widespread musculoskeletal pain. In patients with rheumatoid arthritis (RA), FM can cause an additional symptom burden, which can affect some variables on the RA disease activity score 28 (DAS28), a tool that evaluates 28 joints in RA patients.

OBJECTIVE:

Compare the results of four different versions of the DAS28 and the parameters used to determine disease activity scores in RA patients with and without FM, and determine whether there are treatment differences between RA patients with and without FM.

DESIGN:

Retrospective, cross-sectional.

SETTING:

Tertiary hospital.

PATIENTS AND METHODS:

We identified patients diagnosed with RA between 1 September 2016 and 1 February 2020 and identified patients with and without FM.

MAIN OUTCOME MEASURES:

Differences between variables in the DAS28 calculations (tender joint count [TJC], patient global assessment [PGA], and others), between patients with and without FM, and differences between patients with and without FM who were using or not using biological agents.

SAMPLE SIZE:

381, including 322 females (84.5%).

RESULTS:

The frequency of FM in RA patients was 25.7% (89 females, 24.6%). In RA patients with FM, the TJC and PGA median values were significantly higher than in patients without FM (P<.05). The use of corticosteroids and biological therapy in patients with FM was more frequent than in patients without FM (P<.05). Compared to patients without FM, patients with FM switched treatment more often because of non-response to treatment (P=.01) Median values of the DAS28 scores (calculated by four different versions of the instrument) in RA patients with FM were higher than in patients without FM (P<.05).

CONCLUSION:

The presence of FM in RA patients may affect the subjective variables in different versions of DAS28 scores, causing the disease activity to score higher on the instrument, erroneously indicating worse disease than is actually present.

LIMITATIONS:

A single center, retrospective study.

CONFLICTS OF INTEREST:

None.
“The Perfect Storm”: The Rise of Gender-Based Violence in the Age of COVID-19
Authors:   Marquette High School, Huria Janvi
Published: November 2021

One in three women experiences sexual or physical violence at some point in their life (“A Staggering One-in-Three Women”, 2019). In the last 12 months alone, 243 million girls between the ages of 15 and 49 were subjected to sexual or physical violence by an intimate partner (“Violence against Women”, n.d.). During the COVID-19 pandemic, sudden shifts in routine have made this situation a “ticking time bomb” for the exponential growth in rates of crimes against women (Campbell, 2020).
Contribution of a constellation of two Wide-Swath Altimetry Missions to Global Ocean Analysis and Forecasting

Published: November 2021

Abstract. Swath altimetry is likely to revolutionize our ability to monitor and forecast ocean dynamics. To meet the requirements of the EU Copernicus Marine Service, a constellation of two wide-swath altimeters is envisioned for the long-term (post-2030) evolution of the Copernicus Sentinel 3 topography mission. A series of Observing System Simulation Experiments is carried out to quantify the expected performances. The OSSEs use a state-of-the-art high resolution (1/12°) global ocean data assimilation system similar to the one used operationally by the Copernicus Marine Service. Flying a constellation of two wide-swath altimeters will provide a major improvement of our capabilities to monitor and forecast the oceans. Compared to the present situation with 3 nadir altimeters flying simultaneously, the Sea Surface Height analysis and 7-day forecast error will be globally reduced by about 50 %. With two wide-swath altimeters, the quality of Sea Surface Height 7-day forecasts is equivalent to the quality of SSH analysis errors from three nadir altimeters. Our understanding of ocean currents is also greatly improved (30 % improvements at the surface and 50 % at 300 m depth). The resolution capabilities will be drastically improved and will be closer to 100 km wavelength compared to about 250 km today. Flying a constellation of two wide-swath altimeters thus looks to be a very promising solution for the long-term evolution of the Sentinel 3 constellation and the Copernicus Marine Service.
Quantification of water related soil erosion in the transboundary basin of the Bia (West Africa)
Authors: Meledje N'diaye Edwige Hermann , Kouassi Kouakou Lazare , N'Go Yao Alexis
Published: November 2021

Abstract. In view of the complexity of the phenomenon of water
related soil erosion in the Bia catchment area, linked to a large
heterogeneity of soils, to a very scattered and in some places non-existent
vegetation cover, and to a poorly distributed precipitation in both space
and time, a mapping test of the “specific erosion” random variable is
undertaken. The mapping of the intensity of the erosion hazard was carried
out using the Universal Soil Loss Model (USLE). The map shows that the basin
is generally characterized by relatively moderate erosion rates with an
average erosion rate of 16 t/ha/year.

Published: November 2021

Abstract. The Moulouya watershed presents high risks of water
erosion. The dams built on this river lose each year, by siltation, a volume
of water of about 10 M m3 (Lahlou, 1994). This worrying rate shows that water erosion can
hinder the socio-economic development of the basin if soil protection and
siltation measures are not taken. This study defines the areas most
threatened by water erosion to protect them as a priority. Using a GIS and
the Universal Earth Loss Equation (USLE), we mapped soil losses. The adopted
model determines soil loss from erosivity of rainfall, soil erodibility,
inclination and slope length, soil cover, and erosion control practices. The
possible origins of the deposits alluviating the dams are related to the
products of alteration of the Secondary's carbonate formations and the
Tertiary and Quaternary formations. The modalities of the transport of
deposits of banks of the network of Moulouya are mainly by a suspension. The
specific degradation in the Moulouya watershed is estimated at
214 t/km2/year. Precipitation intensity, steep slopes and deforestation are
responsible for these losses.
Multi-criteria approaches to identify the shoreline retreat downstream of dams: the North African case
Authors: Amrouni Oula , Mahé Gil
Published: November 2021

Abstract. Northern African beaches are among the most vulnerable
areas under the extreme climate change hazard. Mainly sedimentary low-lying
platform, the coasts are supplied by terrestrial yields, which are
increasingly interrupted by dams. Unfortunately, the sediment fluxes are
rarely measured and monitored, so that it is quite impossible today to
assess the contribution of continental sediments to the coast and its
variability. The aim of our study is to determine the sampling protocol of
delta sedimentation plain and nearshore seabed for better understanding of
the anthropogenic driver in contrast to climate change. We adopt a
multi-criteria analysis based both on the geomorphologic feature and the
historic evolution from the River to the littoral plain. The shoreline
evolution reveals an alarming retreat trend reaching −20 m ± 0.15 m yr−1 after the human-induced change where ∼50 % of
sediment discharge has been trapped upstream the dam, including quite all
the coarse material, like sand. The shoreline retreat and the decreasing
sediment rate of fluvial flow are all due to the dam construction.
Reflections on almost a century of hydrological studies on Africa's largest lake
Authors: Sene Kevin , Houghton Carr Helen , Tych Wlodek
Published: November 2021

Abstract. Lake Victoria is the largest lake in Africa and its outflows strongly influence flows in the White Nile, including the availability of water for hydropower generation, irrigation and water supply. Understanding the water balance is a major challenge since the lake is large enough to influence the local climate and its catchment spans several countries. Hydrometeorological monitoring networks are also sparse in some parts of the basin. In this paper, we consider the history of water balance estimates for the lake and how the science has developed as new information and techniques have become available, including in areas such as seasonal flow forecasting and estimating the potential impacts of dam operations and climate change. These findings are placed into a wider context including the challenges arising from a changing climate and evolving ideas from international research programmes, which lead to some suggestions for future research priorities for Lake Victoria and other sub-Saharan/Rift Valley lakes.

Published: November 2021

Abstract. Le taux de sédimentation des barrages du bassin
hydrographique du Cheliff reste le plus élevé de toutes les
régions de l'Algérie. L'oued Mina est un affluent majeur de l'oued
Cheliff, le plus grand oued de l'Algérie qui transporte un taux de
sédiment important et le barrage de Sidi M'Hamed Ben Aouda (Relizane)
qui barre cet oued a reçu un volume de vase égal à 6,7 millions
de m3 par année. L'objectif de cette étude est de proposer un
modèle d'estimation de l'érosion spécifique permettant de
construire un ensemble d'indicateurs afin d'identifier les zones
prioritaires nécessitant le renforcement des moyens de lutte contre
l'érosion et une exploitation meilleure des barrages qui sont la seule
ressource pour l'irrigation et l'activité agricole de la région en
prolongeant leur durée de vie. Nous avons procédé à
l'analyse des données journalières de pluie et de débits des
stations hydro-pluviométriques d'oued El Abtal (de 1985–2010) du sous
bassin versant dont les apports s'accumulent dans le barrage SMBA. Ce
travail nous a permis d'élaborer une carte de sensibilisation qui
délimite les zones vulnérables selon le taux d'érosion
spécifique (Es oued Haddad = 18.3, Es oued El Abd = 7.3, Es oued Mina = 10.47 (t ha−1 an−1) …calculés à partir du
modèle trouvé dans cette étude. Enfin, l'état érosif des
versants a été divisé en quatre classes principales de
vulnérabilité des sols, à savoir  : les niveaux
«négligeable», «modéré», «élevé» et «très
élevé». Cette carte permet de faciliter la prise de décisions
relatives à la priorisation des zones à préserver ou à
restaurer.
