In this paper, we study the concept of S-approximation spaces in fuzzy set theory and investigate its properties. Along introducing three pairs of lower and upper approximation operators for fuzzy S-approximation spaces, ...

Qaleh-Zari is a Fe-oxide Cu-Ag-Au vein type deposit located 180 km south of Birjand, in eastern Iran. Host rocks are mainly Tertiary calc-alkaline to K-rich calc-alkaline with transition to shoshonitic andesite and andesitic ...

Copper-catalyzed S-arylation of thiols can be accomplished using air-stable CuI as a copper source and 1,10-phenanthroline as a ligand in the presence of KF/Al2O3 as a suitable base. This is a simple and efficient method ...

Avian infectious bronchitis is an acute and highly contagious disease that mainly causes respiratory symptoms in poultry. A number of serotypes and variants of the viral agent with poor cross-protection are the major problem ...

Objective(s): This study aims to investigate the pathogenicity and possible mechanisms of S100A9 function in mice models of scleroderma. Materials and Methods: The content of S100A9 in the skin tissues of mice with scleroderma ...

Nowadays, new methods are required to take advantage of the rich and extensive gold mine of data given the vast content of data particularly created by educational systems. Data mining algorithms have been used in educational ...

Rocky intertidal zones are biologically diverse environments with numerous physical stressors; as such, close associations between organisms often develop to overcome such stressors and enhance survival of associates. As ...

Fuller, in 1989, described probiotic microorganisms as “a live microbial feed supplement,which beneficially affects the host animal, by improving its intestinal microbial balance".Saccharomyces cerevisiae var. boulardii ...

Background: Neonatal tumors are usually prenatally diagnosed or within the irst 30 days of life. The true incidence ofneonatal tumors is unknown as a great number of pregnancies with a prenatally diagnosed mass result in ...

Objective(s): This study was undertaken to determine the role of computed tomography (CT)-based methodology to segment the SI joint and quantify the metabolic activity using positron emission tomography (PET). We measured ...

A saddle point variational (SPV ) method was applied to the Dirac equation as an example of a fully relativistic equation with both negative and positive energy solutions. The effect of the negative energy states was ...

This article describes the process of improving risk management practices in a foundry of the ALFET Company (Algeria). The proposed methodology is based on the decision matrix risk assessment technique. This technique ...

Introduction: One of the major concerns in laryngeal laser surgery is the risk of airway fire. The introduction ofwrapped tubes and metal tubes has reduced the fire hazards. However, these tubes are expensive and do not ...

The spent fuel assemblies (FAs) of Bushehr Nuclear Power Plant are planed to be transported by TK-13 casks. Each spent fuel transportation cask holds 12 spent FAs and has a thick steel container to provide shielding. The ...

This study aims to undertake a statistical study to evaluate the accuracy of nine models that have been previously proposed for estimating the ultimate resistance of plate girders subjected to patch loading. For each model, ...

Background: Pain and pruritus are two common symptoms in dermatology that are transmitted with unmyelinated C fibers via substance P. Topical capsaicin is effective due to depletion of never endings from substance P. ...

To reduce the risk of spread of the novel coronavirus (COVID-19), the emerging protocols are advising for less physicianpatientcontact, shortening the contact time, and keeping a safe distance. It is recommended that ...
