Published: March 2022

In this chapter, the correlation between structure and electrical properties of Na2MP1.5As0.5O7 (MII = Co and Cu) are treated. The structural study shows that the cobalt and copper isotype materials can be crystallized in the tetragonal and monoclinic systems, respectively. The electrical study using impedance spectroscopy technique showed that these mixed diphosphate diarsenates are fast electrical conductors; however, the cobalt material exhibited more conductive property than the copper compound. In addition, the powder perovskite manganites La0.7M0.2M’0.1MnO3 (M = Sr, Ba and M’ = Na, Ag and K) have been prepared using the conventional solid-state reaction. The structural, magnetic, and magnetocaloric properties of these perovskite manganites compounds were studied extensively by means of X-ray powder diffraction (XRD) and magnetic measurements. These samples were crystallized in the distorted rhombohedral system with R3c space group. The variation of magnetization (M) vs. temperature (T) reveals that all compounds exhibit a second-order ferromagnetic to paramagnetic phase transition in the vicinity of the Curie temperature (TC). A maximum magnetic entropy change, ΔSMMax, of 4.07 J kg−1 K−1 around 345 K was obtained in La0.7Sr0.2Na0.1MnO3 sample upon a magnetic field change of 5 T. The ΔSMMax values of La0.7Ba0.2M’0.1MnO3 are smaller in magnitude compared to La0.7Sr0.2M’0.1MnO3 samples and occur at lower temperatures.

Authors: Ayad Amel , Mutelet Fabrice , Negadi Amina 
Published: March 2022

In this work, a new group contribution method was used for calculating gas-to-ionic liquid partition coefficients (log KL) of molecular solutes in ILs with a temperature-dependent linear solvation energy relationship. About 36 group parameters are used to correlate 14,762 log KL data points of organic compounds in ionic liquids. The experimental log KL data have been collected from the published literature for different solutes in ionic liquids at different temperatures within the range of 293.15–396.35 K. The calculated log KL data showed a satisfactory agreement with experimental data with an average absolute relative deviation (AARD) of 6.39%.
Pressure Inhomogeneities across Large Samples Using Gas Pressure Media at Low Temperatures
Authors: Batista Leão Juscelino 
Published: March 2022

In-situ inert gas high pressure vessels for neutron scattering for pressures of up to 1.0 GPa, and temperatures as low as 1.5 K, pose a particular problem due to the P × T phase diagram of the pressure media. Hydrostatic pressure under constant pressure and volume, passing through the pressure versus temperature phase diagram (P × T) of the gas to achieve low temperatures (1.5 K < T < 30 K) will cause an overall pressure reduction at base temperatures of at most 25% of the pressure read at the P × T. A methodology for pressurization to ensure minimal pressure loss as temperature falls below the pressure media phase change and at the same time minimizing pressure inhomogeneity throughout the length of the sample is presented within this work. The technique proved to reduce the isochore loss of pressure by a factor of 5. Moreover, for the first-time direct experimental quantitative evidence of the reduction in pressure inhomogeneities across large samples is reported here, and the average inhomogeneity reduction in pressure across top and bottom of a 45 mm long sample is better than a factor of 3.

Published: March 2022

The objective of this study was to examine the trends of climate change and its subsequent impact on human capital development under the reference of human health and education of rural community of drought prone areas in Western Sidama (6.36°–7.14°N Latitude and 38.01°–38.56°E) of Ethiopia. Tropical Application of Metrology using SATellite (TAMSAT) data of both monthly rainfall and temperature was collected from Ethiopian National Meteorological Agency (NMA) for the period of 1987–2017. Data on perceived climate change; change driven impacts people experienced mainly on their health and education and copying or/and adaptation strategies affected community practiced was collected by employing both survey and participatory rural appraisal (PRA) techniques. In order to collect data from the household level, survey was employed for 400 households who were systematically sampled from 245,592 households of five drought prone administrative districts whereas PRA was employed to collect community level data. Mann–KENDALL TEST AND SEN’S SLOPE ESTIMATES (MAKESENS) and descriptive statistics were employed to analyze these data. The analysis result shows that there is increasing and decreasing trends of both temperature and rainfall, respectively. And increasing trend is statistically significant for temperature (α = 0.05; N = 31). Consequently, this change of climate variables has brought negative impacts on human capital mainly on health and education through various paths. Physiological inconvenience, prevalence of various diseases, and malnutrition were the main paths through which climate change impacts on human health were seen whereas students’ failure in standard exam attributed to a roll over impacts of climate change since early child hood, increasing school dropout rate and decreasing demand of the households to family education mainly owing to diminish in agricultural yields were the education dimension impacts of change in climate variables. Though a temporary migration to less stress adjacent areas, receiving aids and use of health extension services were a household level copying mechanisms observed, the first two were seen to reproduce unintended negative effects such as interethnic conflicts, forcing children to drop the school and aid dependency syndrome among receivers that the household themselves, aid organizations and government should work in consortium on building resilience both at household and community levels.
Politisk effektivitetsfølelse og politisk tillid blandt efterkommere: betydningen af opfattet offentlig modvilje mod muslimer og flygtninge

Published: March 2022

Hvordan påvirkes den politiske integration af etniske minoriteter, når de oplever et politisk klima med udbredt modvilje over for ikkevestlig indvandring? Dette vigtige, men underbelyste spørgsmål undersøges gennem et unikt dansk survey fra 2018 blandt 20- til 30-årige efterkommere og en kontrolgruppe med dansk oprindelse. Undersøgelsen går videre end tidligere studier og analyserer sammenhængen mellem de unge voksnes egen opfattelse af offentlig modvilje mod muslimer og flygtninge og deres politiske effektivitetsfølelse samt politiske tillid. Analysen viser en markant stærkere sammenhæng blandt muslimske efterkommere, og særligt hvis de er meget religiøse, men kun i forhold til ekstern politisk effektivitetsfølelse og politisk tillid. Den interne politiske effektivitetsfølelse står forholdsvis upåvirket tilbage, hvilket indikerer et uudnyttet politisk mobiliseringspotentiale.

Les jeunes de la ville de Yaoundé et la sociabilité dans la pratique du parifoot
Authors: Kouomoun Abdou 
Published: March 2022

Taking a dynamic approach to the study of youth, this article draws on the results of a qualitative study
of young people in Yaoundé to understand the logic behind their participation in sports (soccer) betting
and explore associated forms of sociability. After presenting our theoretical framework and data
collection methodology, we describe the factors encouraging young people to bet on soccer matches.
We then review the various forms of sociability developed in the context of sports betting and explore
underlying determinants. To begin with, reports of gambling winnings by friends and acquaintances, love
for the sport and the richness of soccer culture, etc., serve as motivating factors. Furthermore, precarious
living conditions and the perception of cultural capital acquired through these sports (soccer) betting
shape forms of sociability that support strategies for addressing a range of challenges.

Background
Indigo-containing plant tissues change blue after a freezing treatment, which is accompanied by changes in indigo and its related compounds. Phaius flavus is one of the few monocot plants containing indigo. The change to blue after freezing was described to explore the biosynthesis of indigo in P. flavus.

Methods
In this study, we surveyed the dynamic change of P. flavus flower metabolomics and transcriptomics.

Results
The non-targeted metabolomics and targeted metabolomics results revealed a total of 98 different metabolites, the contents of indole, indican, indigo, and indirubin were significantly different after the change to blue from the freezing treatment. A transcriptome analysis screened ten different genes related to indigo upstream biosynthesis, including three anthranilate synthase genes, two phosphoribosyl-anthranilate isomerase genes, one indole-3-glycerolphosphate synthase gene, five tryptophan synthase genes. In addition, we further candidate 37 cytochrome P450 enzyme genes, one uridine diphosphate glucosyltransferase gene, and 24 β-D-glucosidase genes were screened that may have participated in the downstream biosynthesis of indigo. This study explained the changes of indigo-related compounds at the metabolic level and gene expression level during the process of P. flavus under freezing and provided new insights for increasing the production of indigo-related compounds in P. flavus. In addition, transcriptome sequencing provides the basis for functional verification of the indigo biosynthesis key genes in P. flavus.

Authors: Yetunde Omoboye Helen , Adenike Adedeji Adebukola , Adeniyi Israel Funso 
Published: March 2022

Aims: The prime objective of this study is to determine the taxonomic composition of the zooplankton fauna of Esa-Odo Reservoir in Osun State and determine the spatial (horizontal and vertical) and seasonal variations in the composition, distribution abundance, and community structure of the zooplankton community in the reservoir.
Study design: sampling stations were selected horizontally and vertically to cover the entire zones of the reservoir. Planktonic samples were collected at two months intervals for two years.
Methodology: Samples were collected from the depth using an improvised Meyer’s water sampler. Net and Total plankton were sampled by filtration and sedimentation methods. Planktonic samples were preserved as 5% formalin and 1% Lugol’s solution. Measurement, enumeration, and scaled pictures of the recorded zooplankton were taken using a photomicrograph. The taxonomic composition of zooplankton biota was determined using identification keys. Data analysis was done using PAST Statistical Package. ANOVA was used to determine the spatio-temporal variations.
Results: Fiftyty-three (53) pecies of total zooplankton recorded in this study belong to 4 groups: Rotifera, Cladocera, Copepoda, and Insecta. Rotifera was the most represented group (61.21%). Horizontally, 24 species with the highest mean abundance characterized the lacustrine; while 12 species and 10 species were unique to the transition and riverine zones, respectively. Vertically, most species had their mean abundance decreased from the surface to the bottom of the reservoir. A total of nine (9), two (2) and one (1) species were peculiar to the surface, bottom and mid-depth, respectively. Zooplankton organisms were most abundant during the dry season.
Conclusion: Esa-Odo Reservoir comprised highly diversified zooplankton fauna with great potential to support rich aquatic community and fishery production. The reservoir can be classified as fairly clean based on the abundance of the rotifer group. However, the lake should be subjected to regular proper monitoring because of the presence of some pollution tolerant copepod species identified among the zooplankton fauna.

Conclusion: Clinical presentation associated with SARS-CoV-2 infection was different in each group. The strongest associated factors to predict SARS-CoV-2 infection are: smoking, obesity and diabetes.
Anomalous Connection of the Coronary Artery Causing ST Segment Elevation Myocardial Infarction: A Case Report
Authors: Ech-chenbouli Amine , Arous Salim , Benouna Mohamed Elghali , Rachida Habbal 
Published: March 2022

Background: With an angiographic prevalence approaching 1%, Anomalous connections of the Coronary arteries (ANOCOR) are rare. The term connection is preferred over origin since the coronary arteries do not grow out of the aorta but grow into the aorta from the peri truncal ring of coronary arterial vasculature. Very often these anatomical shapes are incidental findings without clinical impact; however, in some specific cases, clinical symptoms may occur arriving to sudden cardiac death (SCD), this is particularly true when there is a an interarterial course between the ascending aorta and the pulmonary.
Case Presentation: This case is about patient that we receive in emergency department presenting with an inferior ST segment elevation myocardial infarction (STEMI) which was found to be caused by compression of the proximal right coronary artery (RCA) between the aorta and the pulmonary trunk. Surgery was indicated by the heart team for the treatment of this condition.
Conclusions: This case presents a severe manifestation of proximal anomalous connection of the right coronary artery with a “malignant” course between the aorta and the pulmonary artery. This variant has been called malignant because of its association with sudden death especially in young asymptomatic athletes. In current guidelines for symptomatic ANOCOR with interarterial course the treatment recommended is surgery.

Gas flaring is a major contributor to the emission of toxic gases and other gaseous pollutants into the atmosphere. A study was undertaken to establish gas flaring effects on physic-chemical properties of soil under tea plantation in Assam, India. The experimental plot was laid out in 5 x 2 factorial RCBD. The experiment was carried out in small tea grower’s gardens adjacent to OCS-6 at Merbil Majuli and Kothaloni OCS in Dibrugarh district of Assam in the year 2019-20. The experimental plots were laid out at 11 metres away from the gas flaring point. Plots were selected at an interval of 20 metres within the experimental design i.e. D1 (11-31m), D2 (31-51m), D3 (51-71m), D4 (71-91m) and DC (150-170m) where, DC denotes control plot. Soil samples for the study were obtained for two tea growing season i.e. rainy and autumn season from the selected gardens. Soil physical parameters such as bulk density, porosity, hydraulic conductivity, soil temperature and soil moisture and chemical parameters such as pH, organic carbon content, available NPK and electrical conductivity of both effected and control plots were evaluated in the laboratory to check the effect of gas flaring and the results obtained were compared with those from the control plot. The results showed that the soil temperature, soil moisture content, soil organic carbon and available NPK of both Merbil Majuli and Kothaloni were significantly affected by gas flaring with respect to distances. But, the bulk density, soil porosity, hydraulic conductivity, soil pH and electrical conductivity of soil were not affected by gas flaring.

Study Design: Analysis of variance (ANOVA) for two factorial RBD was carried out using OPSTAT.
Place and Duration of Study: The field study was carried out in Shalmari No. 1 near the Tingkhong tea estate of Dibrugarh. The laboratory works were carried out in the Department of Tea Husbandry & Technology and Department of Soil Science, Assam Agricultural University, Jorhat, Assam, between March’19 to February’20.
Methodology: Two tea-growing seasons viz. Rainflush and autumn flush were considered. Samples were collected in four distances at an interval of 0-21 m, 21-42 m, and 42-63 m and beyond 63m (control site). A total of 24 plant samples was collected for both the season with respect to 4 distance and 3 replication. In the case of soil samples, a total of 24 soil samples were collected for both the season.
Results: Plant parameters like water saturation deficit increased in crude oil affected site while decreased the relative turgidity, stomatal count, in the tea plants grown in the contaminated site. Bulk density, pH, organic carbon, and available nutrients in the contaminated site of the soils was increased. However, porosity, hydraulic conductivity and electrical conductivity were low in the contaminated area.
Conclusion: The study reveals oil effluent spillage as a major factor for plant growth and soil quality deterioration and the impact was more pronounced in the vicinity of the drilling point adversely affecting plant physiological, soil physico-chemical parameters.

Aim: This study aimed to determine the prevalence and associated factors of internet addiction among undergraduate clinical medical students of a Nigerian private university.
Study Design: Cross sectional descriptive study
Place and Duration of Study: College of Medicine and Allied Health Sciences, Bingham University, Jos campus, Plateau state, Nigeria, between May and July 2021.
Methods: We included 383 (147 males and 236 females, age range 18 – 49 years) clinical medical students of Bingham University. Data was collected using a self-administered questionnaire which included questions about socio-demographic factors, the pattern of internet use and the standardized Internet Addiction Test questionnaire developed by Dr Kimberly S. Young in 1998. Logistic regression analysis was used to determine associations between internet addiction and various risk factors.
Results: Out of 402 students who were administered questionnaires, 383 completed the questionnaires giving a response rate of 95.3%. Of these, 145 (37.9%) were mildly addicted to the internet, 30 (7.8%) were moderately addicted and 1 (0.3%) was severely addicted to the internet. The mean age of the study participants was 22.7 ± 2.7 years. Logistic regression analysis showed that age (P = .002), and having trouble sleeping (P = .002) were significantly but negatively associated with the development of internet addiction while hours spend on social media (P < .001) was significantly and positively associated.
Conclusions: Internet addiction is an emerging disorder in this era of almost global access to internet facilities.
Giant Cell Arteritis: Does Perivascular Inflammation on Biopsy Lead to Clinical Disease?
Authors: Macklin Michael , Zarbalian Yousef , Wang Li , Hamilton Ronald , Liang Kimberly 
Published: March 2022

Background and Objective: Transmural inflammation of the temporal artery on biopsy is considered strongly suggestive of giant cell arteritis (GCA). Occasionally other inflammation patterns are seen. It is controversial whether these findings predict GCA-like disease. Our objective was to describe the clinicopathologic features in a cohort of patients with temporal artery biopsies to examine outcomes of patients with non-transmural inflammation.
Methods: We examined through retrospective chart review the clinical course from 2010-2020 of patients with temporal artery biopsies from 2010-2012. Biopsy results were divided into 3 groups: GCA transmural inflammation, non-GCA perivascular inflammation and negative. Non-GCA perivascular inflammation included small vessel, vasa vasorum and adventitial inflammation. Endpoints included constitutional and craniofacial symptoms, CRP and ESR levels, ASCVD, large vessel complications, and length of steroid treatment.
Results: 95 patients were included. Transmural patients had more visual loss compared with perivascular patients (55.5% vs 15.7%, p=0.004). Transmural patients had more jaw claudication or headache/jaw claudication compared with perivascular patients (44.5% vs 12.6%, p=0.01). Weight loss was more common in transmural patients compared with perivascular (27.8% vs 3.1%, p=0.02). Night sweats, PMR symptoms, and temporal artery tenderness were similar between groups. CRP was higher in transmural patients though not significantly. ESR levels were similar between groups. Transmural patients had a longer steroid duration with a median of 24 months vs 1.5 for perivascular, p=0.001.
Conclusion: Patients with non-transmural inflammation on temporal artery biopsies had improved outcomes when compared with transmural patients. This raises the question of whether steroids should be continued after a biopsy returns with perivascular inflammation.
