In the alluvial aquifers of Upper and Middle Cheliff(North-West Algeria), the groundwater quality is deteriorating. The objective of this study was to characterize the physical and chemical properties of these aquifers;and to evaluate the groundwater quality and its appropriateness for drinking and agricultural use. An investigation was carried out by estimating of the physiochemical parameters(Ca^2+, Mg^2+, Na^+, K^+, Cl^-, SO4^2-, hCO3^-, NO3^-, Br^- and TDS) to identify the chemical characteristics of groundwater. Morever, the isotopic composition was examined to identify the sources of recharge of these aquifers. The groundwater geochemistry for the high water level(May, 2012 and June, 2017) and low water level(November, 2012 and October, 2017) was studied. Accordingly, water samples from 39 water sampling points were collected(October, 2017 and June, 2018), for the purpose of analyzing stable isotopes(18O, 2h). The results show that the groundwater is mainly characterized by Ca-Cl and Na-Cl type. The chemical quality of the water is from fair to poor with the presence of nitrates used in agricultural and urban discharge. Also, the Br/Cl ratio gives indications on the origin of the salinity. This salinity is due to the leaching of chlorinated fertilizers, the dissolution of evaporite deposits and the rise of deep salty water by the fault of Chellif. While, the diagram of δ2h=f(δ18O) indicates that the origin of the recharge of these aquifers is the Atlantic and Mediterranean oceanic meteoric rainwater.

In this paper, we prove some results concerning the existence of solutions for some nonlinear functional-integral equations which contain various integral and functional equations that are considered in nonlinear analysis. Our considerations will be discussed in Banach algebra using a fixed point theorem instead of using the technique of measure of noncompactness. An important special case of that functional equation is Chandrasekhar’s integral equation which appears in radiative transfer, neutron transport and the kinetic theory of gases [1].

Erythema nodosum (EN) is a delayed hypersensitivity response that may be triggered by a range of conditions, including infections and vaccines. Rare cases of EN caused by COVID-19 were recently reported but none due to COVID-19 vaccines were documented. We report here a case of EN occurring after COVID-19 vaccination. Patient presented with painful nodular lesions of all 4 limbs, evolving for one month. These lesions appeared 48 h after the second dose of COVID-19 vaccination. The patient reported no recent infectious episodes. The physical examination found numerous, erythematous dermohypodermatitis knots with no palpable adenopathy. Some were regressive according to biligenesis shades. Biology and radiology findings eliminated other common causes of this dermatosis. The skin biopsy was done and suggested EN. The final diagnosis was post COVID-19 vaccine EN. Patient received a symptomatic treatment and had a slight improvement of the lesions 10 days after diagnosis. Physicians should be aware of the side effects of the vaccine including skin manifestations, especially since more people are bound to be vaccinated.

Current efforts in sorghum breeding programs are exploiting genotyping-by-sequencing (GBS) data to provide full-genome scans for desired traits. The aim of this study was to utilize GBS approach for the identification of genomic regions associated with stress response in sorghum (Sorghum bicolor L. Monech) accessions. DNA samples of twenty sorghum accessions, having different response to drought, were used to prepare GBS libraries for sequencing. SNPs were called using the TASSELGBS pipeline and the tags that present at least 10 times in the dataset were considered and aligned to the reference genome of Sorghum bicolor. The identified SNPs were all compared with the published sorghum transcript related to stress response gene activity. Overall;94.40% tags were aligned and 69,736 putative SNPs positions were identified. Blast search revealed homology to annotated heat and drought–tolerance associated genes which code for ATPases, Peroxidase, hydrophobic protein LTI6A, Aquaporin SIP2-1, Aconitate hydratase and phosphatidylinositol-4-phosphate-5-kinase. The phylogeny of the 20 accessions was constructed using the generated SNPs data. Phylogenetic analysis data showed that the phenotypically tolerant line (El9)?makes a separate cluster and the same for the accessions hSD8653 and hSD5612 near to the cluster that includes most accessions with known post-flowering drought tolerance (hSD7410, hDS10033, hSD8552, GEShEISh and hSD8849). Post-flowering drought sensitive accessions (Tabat, Wadahmed, hSD6468 and hSD6478) formed a separate cluster while the sensitive accession hSD9959 and the tolerant accessions hSD8511 and hSD9566 were distributed between the two clusters. Thus, cluster analysis confirmed the variation among accessions in post-flowering drought tolerance. With further validation, these markers may be used for marker assisted selection for breeding new sorghum genotypes with stress adaptation.

Background: The diagnosis of Non-ST Elevated Myocardial Infarction (NSTEMI) is dependent on elevation of high sensitivity troponin (Hs-troponin). The current cutoff point for Hs-troponin is highly sensitive but not specific for obstructive coronary artery disease (CAD). This study aims to determine the best cutoff point for diagnosing CAD in patients presented with NSTEMI. Methods: Our study included all patients admitted as NSTEMI that underwent coronary angiography (CAG). They were grouped into two groups: A and B. Group A has obstructive CAD of 70% or more stenosis and group B with non-obstructive CAD. Patients were assessed for their demographics, clinical history, laboratory and imaging results. Using SPSS version 22, the pooled cohort of patients were analyzed at significant level 0.05 and the data were tested for significant correlations between two predetermined groups. Results: Group A comprised 87.6% of the patients and both groups had a median age of 53 years. In Group A, 91% were males, 54% diabetics, 54% hypertensives, and median Hs-troponin was 145 ng/L. While in group B, 88% were males, 39% diabetics, 60% hypertensives, and median Hs-troponin was 54 ng/L. There was significant correlation between the two groups in the percentage of diabetes and median troponin level (p
