Feasibility study of a grid-connected PV/wind hybrid energy system for an urban dairy farm.

This study evaluates the energy efficiency of an urban dairy farm in Tlemcen, Algeria, by assessing the feasibility of a grid-connected photovoltaic (PV)/wind hybrid energy system. Using HOMER and MATLAB software, the study explores the potential for replacing the farm's existing energy systems with a hybrid system integrated into a low-voltage electrical grid. The HOMER software determined the configuration that resulted in the lowest net present cost, energy cost in kWh, greenhouse gas emission mitigation, and renewable fraction (RF).

The Immunomodulatory Effects of Selenium: A Journey from the Environment to the Human Immune System.

Selenium (Se) is an essential nutrient that has gained attention for its impact on the human immune system. The purpose of this review is to explore Se's immunomodulatory properties and to make up-to-date information available so novel therapeutic applications may emerge. People acquire Se through dietary ingestion, supplementation, or nanoparticle applications.

Very rare tumor of the nasal cavity, hamartome adenomatoid respiratory epithelial chondro-osseous (COREAH): About a case.

Introduction And Importance: Chondroosseous respiratory adenomatous epithelial hamartoma (COREAH) is a rare benign lesion of the nose and sinuses, with some cases reported in the literature.

Clinical Case: We present here a case of COREAH, in a woman whose clinical examination finds a polypoid mass in the left nasal cavity. Computed tomography (CT) and magnetic resonance imaging (MRI) confirmed the presence of a large mass in the anterior nasal cavity extended to the cranial cavity through the screened blade on the right side.

Haze factor of silver nanowires in variable refractive index environment: experimental and simulation approaches.

While silver nanowires (Ag NWs) have been demonstrated as a highly efficient transparent conducting material, they suffer from strong light scattering, which is quantified by a large haze factor (HF) in the optical spectrum. Here we investigate the influence of the dielectric environment on the light scattering of Ag NWs by comparing experimental measurements and simulations. In air, two peaks on the HF spectra are observed experimentally at the wavelength of= 350 nm and= 380 nm and are attributed by simulations to the influence of the Ag NWs pentagonal shape on the localized surface plasmon resonance.

Inorganic and Organic Selenium Speciation of Seleno-Yeasts Used as Feed Additives: New Insights from Elemental Selenium Determination.

Seleno-Yeasts (SY) used as feed additives are known to contain different Selenium (Se) species. Seleno-Yeasts has been shown, on previous analytical methods, to contain selenomethionine (SeMet), selenocysteine (SeCys), selenate (Se) and selenite (Se), and various other organic and inorganic Se forms identified but rarely quantified. A new advanced method has allowed elemental Se (Se), an inorganic Se species, to be quantified, thereby obtaining better insight into the proportion of inorganic Se in SY products.
