Published: February 2022

Abstract: At present, natural fibers of renewable resources offer the potentiality to act like a reinforcing material for manufacturing of composites. This study provides the effect of fiber volume ratio on physical & mechanical properties of specimen when the fiber length is fixed and randomly oriented. For the fabrication of composite samples, the natural fiber was used as a reinforced material and adhesive material was Phenol-Formaldehyde. Fibers of hemp, coconut & jute are used in equal ratio for the research work. In this study the fiber length was fixed in all samples and the fibers were randomly orientated and the thickness of all samples was 5mm. The length of the fibers was 12mm. A total of four samples S1, S2, S3, and S4 were fabricated using hand lay-up method. Fiber volume ratio is varied from 30% to 60%, such as 30% in S1, 40%in S2, 50% in S3 & 60% in S4 sample. Physical & Mechanical Testing has been carried out as per standards on the prepared specimens. Water absorption test was carried out in two sets one for 2 hours & second for 24 hours. Result shows that fiber volume ratio of 40% in S2 showed maximum density, water absorption test was found minimum for 2 and 24 hours test & minimum moisture. At 30% fiber ratio (S1) the expansion in length, width, and thickness was found minimum during the dimension expansion test for 2 hour soaking. Modulus of elasticity of the composite was found maximum at 50% fiber ratio (S3) inside composite and modulus of rupture found maximum at 60% fiber ratio (S4). The study on the effect of fiber ratio on mechanical and physical properties has been done.
Lightweight URL Phishing Detection System Using SVM and Similarity
Authors: Musa Khan Danish
Published: February 2022

Abstract: As a criminal offense of employing technical method to thieve sensitive information of customers, phishing is presently an important risk facing the net, and losses because of phishing are developing regularly. function engineering is essential in phishing website detection answers; however, the accuracy of detection critically relies upon on earlier knowledge of features. furthermore, even though features extracted for one-of-a-kind dimensions are more comprehensive, a disadvantage is that extracting those functions calls for a massive amount of time. To address those barriers, we propose a multidimensional characteristic phishing detection method based on a quick detection approach by way of the usage of deep mastering (MFPD). within the first step, character sequence functions of the given URL are extracted and used for brief class by means of deep mastering, and this step does not require 1/3-party assistance or any prior know-how approximately phishing. inside the 2d step, we combine URL statistical functions, webpage code features, website text capabilities and the short classification end result of deep studying into multi-dimensional features. The technique can lessen the detection time for putting a threshold.

Authors: Bhusari Rushikesh
Published: February 2022

Abstract: People who suffer from diabetes are at risk of developing blindness since their pancreas doesn't produce enough insulin. Diabetic retinopathy is a condition in which a patient's vision gradually worsens as the disease advances. To better understand how diabetes affects the eye, retinal images captured with a fundal camera can be helpful. This study aims to detect blood vessels, identify hemorrhages, and classify different phases of diabetic retinopathy into normal, mild, and non-proliferative diabetic retinopathy (NPDR). When it comes to classifying the various stages of diabetes-related retinopathy, the retinal picture is used as a starting point. Using the contrast between the blood vessels and the surrounding background, the retinal vascular is segmented.. Density analysis and bounding box approaches were used to identify potential hemorrhage sites. According to blood vessel and hemorrhage area and perimeter, Random Forests technique was used to finally classify various phases of eye disease. Keywords: Retina, blood vessel, hemorrhages, classification, diabetic retinopathy.

Labor force shortage in Russian regions
Authors: Ryazantsev Sergey V. , Bragin Alexey D. , Ochirova Galina N.
Published: February 2022

The article provides an overview of the current state of the labor market in the regions of the Russian Federation, analyzes the level and reasons for the shortage of labor resources, and the factors that have a direct impact on it. It was determined that the main problem is the shortage of labor resources caused by different reasons, such as unemployment, difficult demographic situation, and other complex factors since the federal subjects of Russia are highly differentiated by the level of socio-economic development, demographic, economic, social, geographic, climatic, and other characteristics. In the empirical part of our study, we identified relevant indicators that, in our opinion, fully highlight the changing situation in the regions as well as calculated the percentage dynamics of the level of registered unemployed and the need of organizations to fill vacancies. Subsequent empirical comparative analysis of selected indicators in three-year dynamics reveals that the need of organizations for workers to fill vacancies has an increasingly dynamic, while the unemployment rate is decreasing what shows a satisfactory dynamic. Based on the data obtained, it can be concluded that the shortage of labor resources is evident only in the Belgorod region, the Republic of Mordovia, and the Republic of Buryatia.

El presente artículo es un estudio de caso interpretativo que intenta evaluar la teoría de la sociedad del riesgo a partir de la gestión estatal de la pandemia por COVID-19. Para esto, se enfoca en Costa Rica como unidad de análisis en tanto se busca probar que, a diferencia de lo que apunta la teoría, la carencia material y el nivel de desarrollo, por sí solos, no explican el crecimiento y prosperidad de los riesgos. En cambio, para el presente trabajo se argumenta que, si se busca entender tanto el crecimiento como la prosperidad de los riesgos, es necesario examinar cuáles son las acciones estatales para gestionar dichos riesgos.

Published: January 2022

Background/Objectives. Despite advances in the treatment of sickle cell
disease (SCD), cerebrovascular and cognitive consequences can be
lifelong. Hematopoietic cell transplantation (HCT) is an established
curative therapy and recent studies have demonstrated efficacy with
reduced toxicity nonmyeloblative (NMA) regimens, but little is known
about neuropsychological outcomes. The objective of this study was to
describe neuropsychological, behavioral, and quality of life outcomes
with medical correlates in children with SCD who received an NMA matched
sibling donor (MSD) HCT. Design/Methods. This retrospective cohort
analysis of nine patients with hemoglobin SS SCD underwent MSD HCT using
the National Institutes of Health (NIH) NMA protocol. Results. Mean full
scale intellectual functioning (FSIQ) was average pre-HCT (FSIQ=92.1, SD
9.0; n=8) and 2 years post-HCT (mean FSIQ=96.6; SD 11.1; N=9).
Neuropsychological functioning was largely average across all cognitive
domains. Moderate improvements were seen in processing speed and verbal
memory (Cohen’s d=0.50-0.57) post-HCT, and declines occurred in measures
of attention and fine motor speed and dexterity (Cohen’s d=0.70-0.81).
Parents reported improved quality of life (Cohen’s d=0.91), less impact
of SCD on their family, and less worry about their child’s future
(Cohen’s d=1.44). Exploratory analysis showed relationships between
pre-HCT hemoglobin (r=0.74, p<0.05) and creatinine (r=-0.75,
p<0.01) with cognitive functioning, and a positive
relationship between processing speed and time post-HCT (r=0.73).
Conclusion. Neuropsychological functioning in a sample of children and
adolescents treated identically with NMA MSD HCT remained stable or
improved in most cognitive domains, and improvements in quality of life
and family functioning were observed.
Combination of Atrioventricular valve stenosis and regurgitation in fetal heart, a rare but a clinically significant anomaly: A case study
Authors: Nayak Krishnananda , Nayak Sahana , M Umesh Pai , V Rekha , G Shyamala
Published: February 2022

We illustrate a case of atrioventricular valve stenosis associated with
insufficiency detected in fetal echocardiography performed in a pregnant
woman (22 gestational weeks) of 3rd gravida. The early prenatal
diagnosis demonstrated, isolated bilateral atrioventricular value
stenosis and insufficiency in the absence of any other associated
complex congenital heart diseases such as tricuspid atresia, hypoplastic
left heart syndrome, endocardial cushion defect. However, the mother of
the affected foetus was found to be normal with no risk factors. Thus,
fetal echocardiography plays a pivotal role even in low risk pregnancies
for early detection of prenatal cardiac anomalies that guide the
obstetricians in determining the risk stratification, therapeutic
strategies and prognosis.
Meta-analysis suggests variable, but pCO2-specific, effects of ocean acidification on crustacean biomaterials
Authors: Siegel Kyle , Kaur Muskan , Grigal A. Calvin , Metzler Rebecca , Dickinson Gary
Published: February 2022

Crustaceans comprise an ecologically and morphologically diverse
taxonomic group. They are typically considered resilient to many
environmental perturbations found in marine and coastal environments,
due to effective physiological regulation of ions and hemolymph pH, and
a robust exoskeleton. Ocean acidification can affect the ability of
marine calcifying organisms to build and maintain mineralized tissue and
poses a threat for all marine calcifying taxa. Currently, there is no
consensus on how ocean acidification will alter the
ecologically-relevant exoskeletal properties of crustaceans. Here, we
present a systematic review and meta-analysis on the effects of ocean
acidification on the crustacean exoskeleton, assessing both exoskeletal
ion content (calcium and magnesium) and functional properties
(biomechanical resistance and cuticle thickness). Our results suggest
that the effect of ocean acidification on crustacean exoskeletal
properties varies based upon seawater pCO and
species identity, with significant levels of heterogeneity for all
analyses. Calcium and magnesium content were significantly lower in
animals held at pCO levels of 1500-1999 μatm as
compared to those under ambient pCO. At lower
pCO levels, however, statistically significant
relationships between changes in calcium and magnesium content within
the same experiment were observed: a negative relationship between
calcium and magnesium content at pCO of 500-999
μatm and a positive relationship at 1000-1499 μatm. Exoskeleton
biomechanics, such as resistance to deformation (microhardness) and
shell strength, also significantly decreased under
pCO regimes of 500-999 μatm and 1500-1999 μatm,
indicating functional exoskeletal change coincident with decreases in
calcification. Overall, these results suggest that the crustacean
exoskeleton can be susceptible to ocean acidification at the
biomechanical level, potentially predicated on changes in ion content,
when exposed to high influxes of CO. Future studies
will need to accommodate the high variability of crustacean responses to
ocean acidification, as well as ecologically-relevant ranges of
pCO conditions, when designing experiments with
conservation-level endpoints.
Is it time for a moratorium on the use of benzalkonium chloride in eye drops?
Authors: D'andrea Luca , Montemagni Marina , Celenza Giuseppe , Iorio Roberto , Costagliola Ciro
Published: February 2022

Benzalkonium chloride (BAC) is a quaternary ammonium compound commonly
employed as a preservative in several multidose eye drops. Its use is
associated with several adverse events, particularly when used
chronically. Topically instilled BAC acts not only on superficial
structures but also reaches deeper tissues (trabecular meshwork, optic
nerve) and can be deleterious in patient under chronic treatment. In
glaucomatous patients, BAC is the primary cause of ocular surface
disease (OSD), and it can lead to significant morbidity, influence
treatment compliance, quality of life, and surgical outcomes. Clinical
and experimental evidence demonstrates that BAC causes instability of
the tear layer, loss of goblet cells, apoptosis, subclinical
neuroinflammation, and antibiotic resistance. Considering the validity
of the alternative formulations (alternative preservatives or
preservative-free formulations) it is unreasonable to persist in using
such toxic compounds and, perhaps it is time for a moratorium on the use
of BAC in eye drops.

Published: January 2022

This study focuses on enhancing students' performance through data mining techniques to reduce the challenges of low grades associated with some students in higher institutions in Nigeria. Presently, the amount of data stored in most higher institutions' databases are increasing rapidly. Nevertheless, some higher institutions still rely on paper files to store students’ results. Even those institutions with databases do not know what to do with their data after graduating the students. Thus, this study proposes a method that will use data mining techniques such as the k-nearest neighbor's algorithm to extract the hidden knowledge available in the higher institution databases. The proposed method of classifying students' performance is useful in identifying the poor students by providing the framework that will guide them to acquire better grades or change to other departments where they may be better suited. Keywords: Advisory, classification, data mining, KNN, performance.

This study investigated principals’ instructional supervision of teachers’ instructional strategies and assessment methods correlate of students’ academic performance in Business Studies in junior secondary schools in Taraba State. Two research questions and two hypotheses guided the study. The study adopted correlational survey research design using a questionnaire to collect its data. The population of this study consisted of 97 Business Studies teachers. As a result of the relative small size of the population (97), census sampling technique was adopted that allowed all the population to be used. A self-developed questionnaire titled “Principal’s Instructional Supervision of Business Studies Teachers’ Questionnaire (PISBSTQ)” was used for data collection. The instrument was validated by 3 experts from the department of Physical Sciences Education of Modibbo Adama University, Yola and trial tested using Cronbach Alpha to get a reliability co-efficient of 0.76. The data obtained were analysed using mean and standard deviation to answer the research questions; while Pearson’s Product Moment Correlation (PPMC) was used to test the hypotheses at 0.05 level of significance. The results of the study revealed that; there is a significant high positive relationship between principal’s supervision of teachers’ instructional strategies and students’ academic performance in business studies in junior secondary schools in Taraba state (r = 0.977, p < 0.05); and also that there was a significant high positive relationship between principal’s supervision of business studies teachers’ assessment method and students’ academic performance in junior secondary schools in Taraba State (r = 0.980, p < 0.05). The study concluded that principal’s instructional supervision of teachers’ instructional strategies and assessment method correlates of students’ academic performance in Business Studies.

The rapid increase in the use of information technology has made cyber-attacks a major concern in the use of internet by users globally. These attacks are carried out in different forms, some are carried out as phishing, man in the middle, malicious applications and so on. In this study we will focus on malware attack. Malicious applications have been a major challenge in the use of applications on windows operating system. These malicious attacks are being carried out in different forms. Some of these attacks are trojan, ransom, keylogger etc. The need to detect and classifier these malicious attacks in windows operating system is an important task. So therefore, this paper presents a smart system for detecting and classifying eight categories of malware attack on windows operating system using random forest classifier. The system starts by collecting signatures of malware attack on windows from Virus Share, Virus Sign and Github respiratory. The collected malware signatures went through the following stages of preprocessing (First stage, Second Stage, and Third Stage). The first stage has to do with creating a pandas. Dataframe using the malware signatures. The second stage has to with data cleaning and the third stage has to do with data transformation. The result of the Random Forest Classifier shows a promising performance in terms of accuracy, precision, f1-score, and recall. The result shows that the Random Forest Classifier has an accuracy of about 100% for each of the matrix evaluation.

The continuous improvement in technology underscores the critical need for an efficient home security system to address the prevailing security concerns (such as intrusion and fire outbreaks) in homes. Noticeably, automated home security systems that rely on PIR sensors, smoke sensors, microcontrollers, and android enabled remote monitoring features have huge advantages over manual systems. These automated systems increase the possibility of eradicating security fears in homes by providing homeowners with a good sense of security each time they are away from their homes. This paper reviewed some of the existing techniques previously used to implement advanced home security systems and present a system that notifies homeowners in the event of an intrusion or fire incident in their homes. In addition, the system provides homeowners with a remote monitoring feature via an Android application to stream live events using the cameras or channels provided in the DVR.

The Changing Nature of New Employees’ Orientation: “Staff Retention and Turnover Reduction” An Empirical Study In The Gambia's Public And Private Sectors
Authors:   Dept of Human Resource & Labor Management, American International University West Africa The Gambia,, Onochie Abraham Lawrence
Published: January 2022

Purpose: One of the major areas on HRM is how to develop employees and get the most efficient out of them by retaining employees and reducing an organization's turnover rate. People leave organizations all the times, depending on various reasons that might be personal and out of the control of the employee, and/or either due to conflict of interest of employees seeking a change in their careers. There are various possible factors of the range of control of the organization. However, it has been observed that organizations can keep their employees longer if they are oriented and welltrained. In this paper, investigation will be on the impact of employees' orientation as a tool towards reducing high turnover rates. Methodology: Both primary and secondary data were used to gather information for this investigation. The secondary data was obtained from articles, blogs, papers online, and textbooks. The questionnaires were sent to respondents electronically via Google forms. A link was produced: Https://forms.gle/GEgBCklkmlkMXmL9 after the survey was built, it was shared amongst respondents with an attached letter of clarification explaining the process of participation which was on voluntary basis. The survey was opened for a span of one week and within a week 144 surveys were filled and submitted above the benchmark which targeted 100 participates. The targeted audience was a random selection of The Gambia’s workforce, there was no specific organization under reviewed. Findings: The Statistics of this survey shows that very few numbers of employees stayed with an organization for more than 5 years of employment which indicates a high turnover. Over 73% of the respondents received orientation prior to job engagement with little and/or less information about how to do their jobs. Whereas, over 27% of employees never received any orientation. Results also show that management does not get involved often in ensuring that their newly hired employees understand what-to-do? And how-to-do-their jobs, rather most employees ended up learning their jobs by themselves. Finally, this survey recorded 38% for employees’ feedback and 66% of the time management does not respond to staff feedback. Feedback is one of the most ideal ways of improvement but management concentrates less on it. On the side of training and development, 42% of the respondents believe that orientation helps in reducing the rate at which people leave an organization. While 36% feel neutral about this statement and 50% of the respondents believe that orientation helps in retaining employees. Keywords: Employee Retention, Organization's Turnover Rate, Employment

Published: February 2022

The human X chromosome analysis has been applied to decipher the genetic
structure of populations for applications in medical genetics and for human
identification, parentage analysis and kinship analysis. Although it has not
been studied on vast level with regard to human populations with comparison
to other of its counterparts like autosomal markers, Y chromosome and mtDNA
yet it is important for great potential in studying oncology, various
diseases and forensic science applications. In this mini review, a snapshot
of X chromosomal properties as genetic marker has been entailed. The
structure and potential multiplex oriented kits utilizing X chromosomal
markers have been discussed. Moreover, concerns of different researchers
over X chromosomal published data have been referred to point out need of
analyzing X chromosomal markers to unravel their role in population
genetics, medical genetics and human identification.
