Examining temporal trends in heavy metal levels to analyze sediment pollution dynamics in the Saida urban watershed (N-W Algeria).

The study focuses on current pollution in the Saïda basin, a semi-arid region in north-western Algeria. By analyzing sediments, the study provides interesting results on urban pollution and its environmental impact. The research consists of two main phases, each addressing different aspects of pollution.

A survey into the utilization of probiotics and medicinal plants among individuals afflicted with gastrointestinal disorders in healthcare institutions in Saïda, Algeria.

Functional gastrointestinal (GI) disorders are recognized as a major public health concern worldwide. These disorders involve persistent digestive symptoms indicative of digestive tract dysfunction. A survey examining the utilisation of probiotics and medicinal plants as supplementary treatments was conducted on 160 patients with GI disorders at healthcare institutions in Saïda from March to April 2023 using questionnaires that had been previously adapted and tested for reliability with Cronbach's alpha test.

Panel data on the impact of democracy and political stability on economic growth in the MENA region over the years 1983-2022.

This panel dataset contains information collected from five distinct sources on the impact of democracy and political stability on economic growth in 15 emerging countries in the MENA region from 1983 to 2022. The dataset includes information about GDP per capita, inflation, trade, population growth, government expenditure, participatory democracy, deliberative democracy, egalitarian democracy, institutionalized autocracy, and political stability. Data analysis was carried out utilizing R statistical software to ensure the accuracy of the data by imputing missing data using the monotone REG approach, allowing future researchers to investigate the linkage between political factors and growth in various scenarios.

Ferro-piezoelectricity in emerging Janus monolayer BMX (M = Ga, In and X = S, Se): investigations.

Nanoscale materials with inter-correlation characteristics are fundamental for developing high performance devices and applications. Hence theoretical research into unprecedented two-dimensional (2D) materials is crucial for improving understanding, especially when piezoelectricity is merged with other unique properties such as ferroelectricity. In this work, an unexplored 2D Janus family BMX (M = Ga, In and X = S, Se) corresponding to group-III ternary chalcogenides has been explored.

Studying the effect of polymethyl methacrylate polymer opticals fibers (POFs) on the performance of composite materials based on the polyether ether ketone (PEEK) polymer matrix.

More recently, various techniques have been implemented for the sensors manufacturing purpose, such as fiber Bragg gratings fibers (FBG) that allows variable core refractive index suitable for a large scale of measurements types, fiber optic evanescent waves (FOEW) for water parameters measurement, microstructured and crystal photonic optical fibers, polymers optical fiber (POFs), and so on. In this perspective, the objective of this work is to study the reliability and the origin of the resistance of each fiber-matrix interface of the composite materials PMMA/PEEK, Topas/PEEK, and Topas-Zeonex/PEEK. The genetic simulation is based on the probabilistic approach of Weibull to calculate the damage at the interface by crossing the two damages of the matrix and the fiber respectively.

Recent Insights Into Electronic Performance, Magnetism and Exchange Splittings in the Cr-substituted CaO.

The first-principles computations of density functional theory are employed to characterize the structural properties, electronic structures, and ferromagnetism induced by Cr impurities in CaCrO compounds at concentrations = 0. 25, 0.5, and 0.

Removal of Zinc from Aqueous Solutions Using Lamellar Double Hydroxide Materials Impregnated with Cyanex 272: Characterization and Sorption Studies.

Removal of heavy metals from wastewater is mandatory in order to avoid water pollution of natural reservoirs. In the present study, layered double hydroxide (LDH) materials were evaluated for removal of zinc from aqueous solutions. Materials thus prepared were impregnated with cyanex 272 using the dry method.
