First principles approach and experimental exploration of a new double perovskite phase Sr(In SnSb)O: evaluation of structural, optical, and dielectric properties.

A new double perovskite phase, Sr(SnSbIn)O, was successfully synthesized a solid-state reaction and comprehensively characterized using both experimental and theoretical techniques. Powder X-ray diffraction was used to determine the crystal structure, while scanning electron microscopy (SEM) revealed a high degree of densification and uniform grain distribution across the ceramic. Raman and Fourier-transform infrared (FTIR) absorption spectra of the powder present broad bands predominantly due to different stretching modes of the various SnO , InO and SbO octahedra in the region = 400-800 cm.

New acid anhydride from with antimicrobial activity assessed through and approaches.

In this study, a novel fatty acid anhydride, named phalarisin 1, was successfully isolated from the ethyl acetate extract of growing in Tunisia. The structural characterisation of the compound was achieved through various spectroscopic techniques including FT-IR, 1D and 2D-NMR spectroscopy, as well as acidic hydrolysis analyses. Remarkably, phalarisin exhibited potent antimicrobial properties against a range of pathogens including , , , and , with minimum inhibitory concentrations (MICs) ranging from 31.

Influence of localized sources and meteorological conditions on dry-deposited particles: A case study of Gabès, Tunisia.

This study investigates the spatial and temporal variations of dry-deposited particles on the surface (by turbulence or gravity) in various sites within Gabès city and its surroundings, South-eastern Tunisia. Monthly samples were collected from five distinct locations: suburban-industrial (S2), suburban-residential (S3), and urban sites (S1, S4, and S5). The average monthly particle deposition flows ranged from 7.

Evaluation of Microbial Phospholipase and Lipase Activity Through the Chromatographic Analysis of Crude, Degummed, and Transesterified Soybean Oil for Biodiesel Production.

The present study aimed at synthesizing fatty acid methyl esters in a combined enzymatic method by applying degumming and transesterification of soybean oil. A soluble lipase from Serratia sp. W3 and a recombinant phosphatidylcholine-preferring phospholipase C (PC-PLC) from Bacillus thuringiensis were used in a consecutive manner for phosphorus removal and conversion into methyl esters.

Soil contamination by trace elements and radioelements and related environmental risks in agricultural soils of the M'Dhilla Basin (southwestern Tunisia).

Agricultural soil contaminated by phosphogypsum pile stocked in plan air remains a major problem in M'Dhilla city southwestern of Tunisia. The present effort aimed to enhance the knowledge of trace elements and radioactivity abundance and to assess the corresponding environment. X-ray fluorescence spectroscopy was used to evaluate the trace elements, radioactive elements, and major element concentrations.

The effect of motor dual-task training on gait and mobility performances in children with intellectual disabilities.

The study investigated the impact of motor dual-task training on gait and mobility in children with intellectual disabilities. Performance was assessed using the Timed Up and Go Test (TUGT) and the 10-Meter Walking Test (TMWT) before and after an 8-week training period, with participants divided into a Trained Group (n=12) and a Control Group (n=14). Results indicated that, across both groups and regardless of session, TUGT and TMWT scores were significantly higher (p < 0.

Integrated processes for olive mill wastewater treatment and its revalorization for microalgae culture.

The olive oil industry generates 30 million cubic meters of olive mill wastewaters (OMWWs) annually. OMWWs are a major environmental concern in the Mediterranean region due to their high organic matter content, suspended solids, unpleasant odor, and dark color. The application of primary treatments such as coagulation-flocculation, adsorption, and hybrid systems combining coagulation-flocculation with adsorption has enabled to remove part of the organic matter, color, turbidity, and growth-inhibiting compounds from OMWWs.

MeSH2Matrix: combining MeSH keywords and machine learning for biomedical relation classification based on PubMed.

Biomedical relation classification has been significantly improved by the application of advanced machine learning techniques on the raw texts of scholarly publications. Despite this improvement, the reliance on large chunks of raw text makes these algorithms suffer in terms of generalization, precision, and reliability. The use of the distinctive characteristics of bibliographic metadata can prove effective in achieving better performance for this challenging task.

Social media addiction and personality dimensions among Tunisian medical students.

Purpose: Social media (SM) has become a common activity for today's young people. It is sometimes overused and potentially results in SM addiction. This study aims to assess SM addiction and its associated factors in medical students and to examine its relationship with dimensions of personality global self-esteem, and social self-esteem.

Association Between the Triglyceride-Glucose Index and Serum Uric Acid to High-Density Lipoprotein (HDL) Cholesterol Ratio in Type 2 Diabetes Mellitus in Gabes City, Tunisia.

Background Type 2 diabetes mellitus (T2DM) is a significant risk factor for cardiovascular diseases (CVD). The triglyceride-glucose index (TyGi) is a novel biomarker for insulin resistance, strongly linked to CVD. Elevated serum uric acid levels and the uric acid to high-density lipoprotein cholesterol ratio (UHR) are emerging as markers of metabolic syndrome and cardiovascular risk in T2DM.

Cervical Lymphadenitis Tuberculosis Coexistent with Metastatic Papillary Thyroid Carcinoma.

Malignant lesions and tuberculosis coexisting at the same anatomical site in a patient are extremely uncommon. We present a case of a 53-year-old female with cervical lymphadenitis tuberculosis combined with metastatic papillary thyroid carcinoma. Thyroidectomy was performed on the patient with central and lateral neck dissection.

The Phylogenomic Characterization of Species and Their Cellulases for Biotechnological Applications.

This study aims to evaluate the in silico genomic characteristics of five species of the genus : , , , , and , with a view to their application in therapeutic research. The 16S rRNA comparison indicated that these species were phylogenetically distinct. Pairwise comparisons of digital DNA-DNA hybridization (dDDH) and OrthoANI values between these studied type strains indicated that dDDH values were below 62.

Watermelon Rind Dietary Fibers as Natural Source to Enhance Texture of Wheat Bread.

The objective of this study was to explore how watermelon rinds (WMRs) and their derivatives, specifically water-soluble polysaccharides (WMRPs) and hemicellulose (WMRH), as sources of dietary fiber, could enhance the quality of wheat bread. The extraction process yielded 34.4% for WMRP and 8.

Are Adolescent Athletes Sleeping Enough? An Observational Study of Sleep Parameters during Schooldays and Holidays.

Inconsistent sleep schedules, frequent awakening after sleep onset (WASO), and decreased sleep efficiency (SE) are common issues among adolescent team sports athletes.
