Background and Aim: It has been shown that Capparis spinosa fruit has hypoglycemic, antioxidant, antiinflammatory, and analgesic properties. The aim of the present study was to determine the effects of Capparis spinosa fruit on histomorphological changes in pancreas after triggering diabetes mellitus in male rats. Materials and Methods: Forty Wistar rats (150- 200 g, 6 weeks of age) were random...
Resumen. Sin lugar a duda el algoritmo K-means es el más utilizado en la comunidad de aprendizaje no supervisado. Desafortunadamente es muy sensible a la selección de los centroides iniciales. Debido a ello, se han propuesto un gran número de métodos para la selección de los centros iniciales. En este artículo se presenta un algoritmo de agrupamiento que tiene como base al algoritmo K-means, en...
Wall-to-bed (or wall-to-fluid) heat transfer issues in trickle bed reactors (TBR) has an important impact on operation and efficiency in this category of reactors. In this study, the hydrodynamic and thermal behavior of trickle bed reactors was simulated by means of computational fluid dynamics (CFD) technique. The multiphase behavior of trickle bed reactor was studied by the implementation of ...
vegetation deterioration is a main cause of erosion and land degradation. therefore, land cover reclamation in the effected areas will affect erosion trend. in reclamation projects, the investigation of relationship between the planted species and soils is highly recommended. atriplex species can sequester carbon into soil, and have an ability to conserve soil and prevent soil erosion, as well....
Background and Objectives: Today, with increasingresistance of bacteria to antibiotics, the use of medicinal plants has increased. The aim of this study was to investigate the antibacterial properties of Carla extract on Escherichia coli and Staphylococcus aureus to investigate the inhibitory properties and to find alternative drugs. Materials and Methods: In this research, the antimicrobial a...
Introduction: Menopause can change the musculoskeletal system by reducing estrogen hormone levels. The aim of this study was to evaluate the effect of regular resistance training accompanied by vitamins D and calcium supplements during pre-menopausal period on muscle tissues of Wistar rats’ postmenopausal period. Methods: In this experimental study, female Wistar rats were randomly divided int...
Background and Aim: Sodium arsenite is an environmental pollutant with the capacity of generating free radicals and tissue damage. The aim of the current study was to investigate the effect of green tea extract (GTE), as an antioxidant, on sperm parameters and testis tissues of the mice treated with sodium arsenite. Materials and Methods: Twenty-four adult male NMRI mice with mean body weight 3...
This study presents the results of large scale laboratory model tests to investigate the behavior of Compacted Lime – Well-graded Soil (CL-WS) rigid stone columns in soft soils. The unit cell idealization is used for construction of composite specimens by evaluating the influence of different parameters such as the diameter of the column (D), the slenderness ratio (L/D) and the area ratio (Ar)...
The aim of this research is preparation of SnO2 nanowires by means of Thermal chemical reaction vapor transport deposition (TCRVTD) method from SnO powders. The morphology, chemical composition and microstructure properties of the nanowires are characterized using field emission scanning electron microscope (FE-SEM), EDS, and XRD. The XRD diffraction patterns reveal that the SnO2 nanowires have...
