Assessment of beach litter pollution in Egypt, Tunisia, and Morocco: a study of macro and meso-litter on Mediterranean beaches.

We conducted surveys of Mediterranean beaches in Egypt, Morocco, and Tunisia including 37 macro-litter (> 25 mm) and 41 meso-litter (5-25 mm) assessments. Our study identified key litter items and assessed pollution sources on urban, semi-urban, tourist, and semi-rural beaches. Macro-litter concentration averaged 5032 ± 4919 pieces per 100 m or 1.

Is Vitamin D Deficiency a Risk Factor for Osseointegration of Dental Implants - A Prospective Study.

Introduction: Early dental implant failure (EDIF) can occur even when optimal materials are used, surgical protocols are strictly followed and the quantity and quality of bone at the recipient site are sufficient. The existence of specific patient-related risk factors require an investigation into the regulatory mechanisms controlling bone metabolism, bone remodelling and bone turnover as well as serum Vitamin D. The implant stability quotient is used as a prognostic indicator for possible implant failure.

An electrochemical, and surface studies of synthesized Gemini ionic liquid as corrosion inhibitor for carbon steel in petroleum field.

In this work, we study the efficiency of N, N-dibenzyl-N, N, N, N-tetramethylpropane-1,3-diaminium chloride, as anticorrosion. This compound exhibits potential as a prospective remedy to stop the deterioration of carbon steel caused by corrosion in 1.0 M HCl.

An abattoir study of the prevalence of foot lesions and claw measurements in water buffalo in Egypt.

Background: Lameness has been associated with compromised animal welfare and reduced productivity in dairy cattle herds worldwide. However, little is known about the prevalence of claw lesions in the dairy buffalo population in Egypt. Furthermore, the optimum measurements for claw trimming in buffalo are unknown.
