Impact of urbanization and economic growth on environmental quality in western africa: Do manufacturing activities and renewable energy matter?

The countries in Western Africa have the greatest potential for renewable energy generation in the world and are likely to be vulnerable to the adverse effects of climate change. Unfortunately, only a few of them have tapped into this potential, as non-renewable energy still dominates the total energy mix of these countries. The present study explores the effect of economic growth, manufacturing value-added, urbanization, financial development, foreign direct investment, and renewable energy consumption on the environmental quality in West African countries by using a sample of some selected countries over the period 1991–2018. This study is analyzed by adopting the method of Driscoll-Kraay (DK) panel regression. The panel result suggests that manufacturing value-added, urbanization, financial development, and foreign direct investment increase environmental degradation. In addition, the findings of this study reveal that economic growth and renewable energy consumption contribute, significantly, to environmental quality. Bidirectional causality exists between economic growth and CO2 emissions and between urbanization and environmental degradation. Accordingly, in order to improve environmental quality in these countries, it is imperative to embrace and promote the consumption of clean energy sources, which will contribute more to the promotion and adoption of renewables in this strategic region.
The Geochemical Evolution of Santa Cruz Island, Galápagos Archipelago

Understanding how ocean island volcanoes evolve provides important insight into the behavior of mantle plumes, how plumes interact with mid-ocean ridges, and potential risks posed to inhabitants as the islands age. In this field-based study of the Galápagos Islands, we use radiogenic isotope ratio, major element, and trace element analysis of >70 new lava samples to document the geochemical evolution of Santa Cruz Island over the past ∼2 million years, as it has been carried away from the plume. Currently, Santa Cruz is a dormant shield volcano in the central archipelago. Previous work indicates that exposed lavas preserve >1 million years of activity in two eruptive units: 1) The older Platform Series, exposed primarily in the northeast; and 2) the Shield Series, which blankets the rest of Santa Cruz and erupted from a WNW trending fissure system. Our new geochemical analyses indicate that the Platform Series lavas are more evolved and isotopically enriched than Shield lavas, but neither as compositionally monotonous nor as isotopically enriched as the younger western Galápagos volcanoes. Santa Cruz formed when the Galápagos Spreading Center (GSC) was closer to the plume than it is today, resulting in enhanced plume-ridge interaction and transport of plume material to the ridge. Consequently, the Platform Series was formed under relatively magma-starved conditions compared to today’s western volcanoes. Magma supply was sufficient for partial fractionation and homogenization of melts in shallow reservoirs, but inadequate to support thermochemically buffered networks like those in the present-day western archipelago. The slight depletion of Platform Series lavas relative to Fernandina reflects entrainment of depleted upper mantle and/or diversion of deep, enriched plume melts to the nearby GSC. The younger Shield Series lavas are even more depleted because plate motion has carried the volcano across the compositional boundary of the bilaterally asymmetric plume into its more depleted zone. Shield Series lavas’ variable, primitive compositions reflect minimal crustal processing in small, ephemeral, poorly supplied magma reservoirs. Unlike the young western shields, the constructional history of Santa Cruz has been controlled to a significant extent by its proximity to the GSC.
Risk factors of pelvic organ prolapse at Asella Teaching and Referral Hospital: Unmatched case control study

Background Prolapse is one of the sub-types of pelvic floor dysfunction (PFD) which occurs due to abnormal fall of the pelvic organs from their normal anatomic positions. Although the cause of prolapse is multifactorial, it primarily occurs due to pregnancy and vaginal delivery. Hence, the present study aimed to identify risk factors of prolapse among women who undergo gynecological surgery. Materials and methods Facility-based-unmatched case–control design was employed. Cases were all gynecological women who were diagnosed with pelvic organ prolapse (POP) at Asella teaching referral hospital (ATRH) while controls were all charts of gynecological women who were diagnosed with other gynecological problems rather than POP at ATRH. For each case, two controls were selected using a simple random sampling technique. The data were entered into Epidata version 4.3. 1 and finally exported to SPSS version 25 for further analysis. Then variables that had an association in the bivariate model (p < 0.25) were entered and analyzed by a multivariable conditional logistic regression model to identify the independent effect of different factors. Statistical significance was declared at p < 0.05. Results A total of 147 cases and 293 controls were included in this study. Women who had a history of chronic cough, previous pelvic floor surgery, constipation, and vaginal tear during delivery, history of pelvic trauma, age of the women, rural resident, and maternal gravidity were strongly associated with prolapse at p-value of < 0.05. Multigravida [adjusted odds ratio (AOR) 2.987 (95% CI 1.237–6.853), p = 0.014], age >50 years [AOR: 2.496 (95% CI 1.372–4.539), p = 0.003], women with a history of pelvic floor surgery [AOR: 0.3. 666 (95% CI 1.328–10.124), p = 0.012], women who had diabetes mellitus [AOR: 4.676 (95% CI 0.908–24.075), p = 0.065], and resided in rural areas [AOR = 1.878; (95% CI: 0.984–3.585), I2 = 47.5%, p = 0.056] were the independent predictors were of prolapse. Conclusions In this study, women with diabetes mellitus, previous pelvic floor surgery, rural residents, being multigravida, and age >40 were independent predictors of prolapse. Therefore, delivering health education by focusing on the identified risk factors was strongly recommended.
Membranous nephropathy: Systems biology-based novel mechanism and traditional Chinese medicine therapy

Membranous nephropathy (MN) is a renal-limited non-inflammatory autoimmune disease in the glomerulus, which is the second or third main cause of end-stage kidney diseases in patients with primary glomerulonephritis. Substantial achievements have increased our understanding of the aetiology and pathogenesis of murine and human MN. The identification of nephritogenic autoantibodies against neutral endopeptidase, phospholipase A2 receptor (PLA2R) and thrombospondin type-1 domain-containing 7A (THSD7A) antigens provide more specific concept-driven intervention strategies for treatments by specific B cell-targeting monoclonal antibodies to inhibit antibody production and antibody-antigen immune complex deposition. Furthermore, additional antibody specificities for antigens have been discovered, but their pathogenic effects are uncertain. Although anti-PLA2R and anti-THSD7A antibodies as a diagnostic marker is widely used in MN patients, many questions including autoimmune response development, antigenic epitopes, and podocyte damage signalling pathways remain unresolved. This review describes the current available evidence regarding both established and novel molecular mechanisms based on systems biology approaches (gut microbiota, long non-coding RNAs, metabolite biomarkers and DNA methylation) in MN, with an emphasis on clinical findings. This review further summarizes the applications of traditional Chinese medicines such as Tripterygium wilfordii and Astragalus membranaceus for MN treatment. Lastly, this review considers how the identification of novel antibodies/antigens and unresolved questions and future challenges reveal the pathogenesis of MN.
Revised 5 Report on the Algorithmic Language Scheme

The report gives a defining description of the programming language Scheme. Scheme is a statically scoped and properly tail-recursive dialect of the Lisp programming language invented by Guy Lewis Steele Jr. and Gerald Jay Sussman. It was designed to have an exceptionally clear and simple semantics and few different ways to form expressions. A wide variety of programming paradigms, including imperative, functional, and message passing styles, find convenient expression in Scheme.
Towards Stronger Coulomb Coupling in an Ultracold Neutral Plasma

Ultracold neutral plasmas are strongly coupled Coulomb systems that are generated by photoionizing lasercooled atoms close to the ionization threshold. The strong coupling parameter Γ is limited at times later than ∼100 ns by disorder‐induced heating. A recent simulation predicted that higher values of Γ can be realized in ultracold neutral plasmas if the plasma ions are excited to higher ionization states. In this paper we present recent results from an experiment that increases the strong coupling of an ultracold neutral plasma by promoting the plasma ions to the second ionization state. Using laser‐induced fluorescence we map out the ion velocity distribution of the Ca+ ions in a partially doubly ionized plasma and show that the heating due to the second ionization depends on the timing of the second ionization laser pulses. We compare our results to MD simulations, which estimate that Γ increases from approximately 2.5 to 3.6. (© 2015 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
A conjecture on the composition of localizations on a stratified tensor triangulated category

We study the composition of Bousfield localizations on a tensor triangulated category stratified via the Balmer-Favi support and with noetherian Balmer spectrum. Our aim is to provide reductions via purely axiomatic arguments, allowing us general applications to concrete categories examined in the mathematical practice. We propose a conjecture that states the behaviour of the composition of the localizations depends on the chains of inclusions of the Balmer primes indexing said localizations. We prove this conjecture in the case of finite or low dimensional Balmer spectra.
SODAR observations of inertia‐gravity waves in the atmospheric boundary layer during the passage of tropical cyclone

This study reports characteristics of inertia‐gravity waves (IGWs) in the atmospheric boundary layer during the passage of Tropical Cylone‐03B, using the Doppler Sound Detection and Ranging (SODAR) observations at the Indian tropical station of Gadanki (13.45°N, 79.2°E; near the east coast of India). Wavelet analysis of horizontal winds indicates significant wave motion (˜60 h) near the characteristic inertial period. The hodograph analysis of the filtered winds shows an anti‐cyclonic turning of horizontal wind with height and time, indicating the presence of IGW. This study finds important implications in boundary layer dynamics during the passage of tropical cyclones.
ournal of C osmology and A stroparticle hysics CMB and BAO constraints for an induced gravity dark energy model with a quartic potential

We study the predictions for structure formation in an induced gravity dark energy model with a quartic potential. By developing a dedicated Einstein-Boltzmann code, we study self-consistently the dynamics of homogeneous cosmology and of linear perturbations without using any parametrization. By evolving linear perturbations with initial conditions in the radiation era, we accurately recover the quasi-static analytic approximation in the matter dominated era. We use Planck 2013 data and a compilation of baryonic acoustic oscillation (BAO) data to constrain the coupling γ to the Ricci curvature and the other cosmological parameters. By connecting the gravitational constant in the Einstein equation to the one measured in a Cavendish-like experiment, we ﬁnd γ < 0 . 0012 at 95% CL with Planck 2013 and BAO data. This is the tightest cosmological constraint on γ and on the corresponding derived post-Newtonian parameters. Because of a degeneracy between γ and the Hubble constant H 0 , we show how larger values for γ are allowed, but not preferred at a signiﬁcant statistical level, when local measurements of H 0 are combined in the analysis with Planck 2013 data.
Local Power of Fixed‐T Panel Unit Root Tests With Serially Correlated Errors and Incidental Trends

The asymptotic local power properties of various fixed T panel unit root tests with serially correlated errors and incidental trends are studied. Asymptotic (over N) local power functions are analytically derived, and through them, the effects of general forms of serial correlation are examined. We find that a test based on an instrumental variables (IV) estimator dominates the tests based on the within‐groups (WG) estimator. These functions also show that in the presence of incidental trends, an instrumental variables test based on the first differences of the model has non‐trivial local power in an N−1/2 neighbourhood of unity. Furthermore, for a test based on the within‐groups estimator, although it is found that it has trivial power in the presence of incidental trends, this ceases to be the case if there is serial correlation as well.
Evaluation of the relationship between vitamin D3 level and sex hormones in women with PCOS

The current study included collection of 90 serum samples to assess the relationship between the level of vitamin D3 and some biochemical variables in women with polycystic ovarian syndrome. The samples were collected from external laboratories in Salah al-Din Governorate for the period from 10/29/2021 to 12/25/2021. 60 samples were taken for women with PCOS, and 30 samples were taken from the control group, their ages ranged between (18-40) years for healthy women and patients. Vitamin D3 level and some hormones concentrations (luteinizing hormone, follicle-stimulating hormone, and testosterone) were estimated in the blood serum of the study groups. The results of the current study showed that the level of vitamin D3 decreased significantly (P≤0.05) in women with PCOS compared to healthy women as a control group, the results showed a significant increase (P≤0.05) in the level of studding hormones (luteinizing hormone, follicle-stimulating hormone, and testosterone) in women with PCOS compared to healthy women as a control group.
Ambipolar Electric Field Effect in Metallic Bi2Se3

Topological insulators (TIs) constitute a new class of materials with unique properties resulting from the relativistic-like character and topological protection of their surface states. Theory predicts these to exhibit a rich variety of physical phenomena such as anomalous magneto-electric coupling and Majorana excitations. Although TI surface states have been detected in Bi-based compounds by ARPES and STM techniques, electrical control over their density, required for most transport experiments, remains a challenge. Existing materials are heavily doped in the bulk, thus preventing electrical tunability of the surface states and their integration into topological quantum electronic devices. Here we show that electronic transport in metallic Bi2Se3 nanoscale devices can be controlled by tuning the surface density via the electric field effect. By choosing an appropriate high-k dielectric, we are able to shift the Fermi energy through the charge neutrality point of the surface states, resulting in ambipolar transport characteristics reminiscent of those observed in graphene. Combining magnetotransport, field effect, and geometry dependent experiments, we provide transport measurements of the surface state mobility, and identify likely scattering mechanisms by measuring its temperature dependence.
Columnar Metaplasia of the Esophagus Presenting as Iron Deficiency Anemia in Children with Neurologic Impairment or Congenital Esophageal Atresia

Case series Patient: Female, 8-year-old • Male, 15-year-old • Male, 8-year-old • Male, 17-year-old • Male, 11-year-old Final Diagnosis: Columnar metaplasia of the esophagus Symptoms: Iron deficiency anemia Medication: — Clinical Procedure: Esophagogastroduodenoscooy Specialty: Gastroenterology and Hepatology Objective: Rare coexistence of disease or pathology Background: Columnar metaplasia of the lower esophagus includes both gastric and intestinal metaplasia. Children with severe neurologic impairment and congenital esophageal atresia often have gastroesophageal reflux disease, which can lead to Barrett’s esophagus, a form of lower esophageal columnar metaplasia and precursor to esophageal adenocarcinoma, with some, but not all, guidelines specifically requiring the presence of intestinal metaplasia for diagnosis. This case series illustrates how iron deficiency anemia may be the primary symptom of esophageal columnar metaplasia in such children and how upper endoscopy is essential in their initial and ongoing evaluation. Case Reports: We review 5 cases of columnar metaplasia of the lower esophagus in children, 3 with severe neurologic impairment and 2 with esophageal atresia. Each child presented with marked iron deficiency anemia and minimal-to-no gastrointestinal symptoms. Conclusions: We conclude that columnar metaplasia of the esophagus may present with iron deficiency anemia in children with neurologic impairment or congenital esophageal atresia, even if without overt gastrointestinal symptoms. Accordingly, we propose that early endoscopic evaluation should be considered in this specific patient population. Based on our literature review, we also emphasize the need for guidelines on the endoscopic surveil-lance of such children with any type of columnar metaplasia of the lower esophagus, given the associated risk of malignant transformation.
THE STOCHASTIC EVOLUTION OF ASTEROIDAL REGOLITHS AND THE ORIGIN OF BRECCIATED AND GAS-RICH METEORITES

A model is constructed which views regolith evolution on asteroids as a stochastic process. Average values are shown to be poor descriptors of regolith depth. The utility of the average depth is not significantly increased by avoiding large craters or thick ejecta deposits, a procedure adopted in previous regolith studies. The statistical uncertainty associated with regolith depth severely limits the power of regolith models in predicting parent-body size for brecciated meteorites. A Monte Carlo algorithm was used to simulate the random walks and corresponding charged-particle irradiation histories of grains in regoliths. On rocky asteroids, only about 20 percent of the grains was exposed to solar cosmic ray ions. Results based on present-day conditions in the asteroid belt agree well with irradiation features observed in gas-rich meteorites. An origin during epochs of early solar system evolution is not required.

Genetic diversity and population structure of sorghum [Sorghum bicolor (L.) Moench] in Ethiopia as revealed by microsatellite markers

ABSTRACT Ethiopia is the center of origin of sorghum (Sorghum bicolor L.). Understanding of the genetic diversity of the species is fundamental to design appropriate conservation and management strategies. The present study addressed the genetic diversity of sorghum accessions collected from major growing regions of Ethiopia. Eighty sorghum accessions representing five populations namely Amhara, Dire Dawa, Oromia, Southern Nations, Nationalities and Peoples (SNNP) and Tigray were analyzed with 11 simple sequence repeat (SSR) markers. Analysis of molecular variance (AMOVA) was conducted to evaluate genetic variation within and among populations. The unweighted neighbour-joining-based cluster analysis, principal components of analysis (PCoA) and structure analysis were done to elucidate clustering of populations. The polymorphic information contents (PIC) ranges from 0.50 to 0.86. A high within-populations genetic diversity was confirmed with gene diversity values ranging from 0.51 to 0.77. AMOVA revealed 93.26% of the total genetic variation within populations and 6.74% among populations. Cluster analyses did not show clear grouping of accessions according to their geographical origins, confirming gene flow (Nm = 6.65) among populations. In conclusion, the SSR markers used were polymorphic and highly informative Oromia and Amhara populations displayed genetic diversity greater than mean value of 0.67 suggesting possible target populations for breeding and conservation.
