Comparison between Pathogenic Streptomyces scabies Isolates of Common Scab Disease
_STREPTOMYCES SCABIES_ (Thaxter) causes destructive and serious damages to many vegetable field crops, including potato. Fourteen pure isolates were obtained from naturally diseased potato tubers showing symptoms of common scab disease, collected from different localities of Sohag governorate, Egypt. All tested isolates were identified as S. scabies (Stc) according to morphological and biochemical tests. Isolate Stc 10 exhibited the highest ... إقراء المزيد

Evaluation of clinical recovery and healing of oral lesions by 3 different therapeutic regimens in cattle with foot and mouth disease (FMD)
The study compares the clinical outcome of the use of different topical treatments for oral lesions in cattle suffering from foot and mouth disease (FMD). One hundred diseased cattle, during an outbreak of FMD in Assiut governorate, Egypt, were used in this study. The animals divided into four equal groups. The oral lesions after being washed with physiological saline solution ... إقراء المزيد

Parallel binary tree splitting protocol for tag anti-collision in RFID systems

Parallel binary tree splitting protocol for tag anti-collision in RFID systems
This paper describes new tree based anti-collision algorithm for Radio Frequency Identification (RFID). The proposed algorithm is based on parallel binary splitting (PBS) technique to follow new identification path through the binary tree. The dialog between the reader and tags needs only one bit tag response followed by one bit reader reply (one-toone bit dialog). The proposed scheme does not ... إقراء المزيد

Insulin Resistance, Visceral Adiposity Index and TyG Index in Genotype-4 Chronic HCV Patients and Their Relation to Hepatic Histopathology

Insulin Resistance, Visceral Adiposity Index and TyG Index in Genotype-4 Chronic HCV Patients and Their Relation to Hepatic Histopathology
Introduction: Hepatitis C virus (HCV) genotype 4 is the most prevalent in Egypt. Visceral adiposity index (VAI) and (TyG) index are newly developed indices for assessment of metabolic syndrome (MS) and insulin resistance (IR). We aimed at comparing their levels in HCV-patients with healthy controls and validate their use for prediction of hepatic histopathological changes. Patient and Methods: 78 chronic ... إقراء المزيد

Petrology, geochemistry and opaques of mélange rocks along Wadi Abu Haramiya, Central Eastern Desert, Egypt.

Petrology, geochemistry and opaques of mélange rocks along Wadi Abu Haramiya, Central Eastern Desert, Egypt.
The Precambrian basement rocks exposed along Qift- Quseir asphaltic road, central Eastern Desert (CED) of Egypt, exhibits two contrasted tectonic units each of which has its own lithology structural style and grade of metamorphism. The older (lower infrastructural rocks) unit exposed in the Meatiq swell is composed of mylonites, cataclased gneisses, amphibolites and gneissose granite and is intruded by syn-to ... إقراء المزيد

Geochemistry, petrogenesis and fluid inclusion studies of the Kadabora granite pluton and associated enclaves, Central Eastern Desert, Egypt.
_The studied area is occupied by Neoproterozoic basement rocks comprising ophiolitic melange, metagabbro-diorite complex, younger granites and post-granite dykes._ _Detailed field studies revealed that Kadabora pluton is differentiated into three phases: granodiorite phase I, monzogranite phase II is and finally syeno- alkali feldspar- granite phase III._ _Mafic enclaves (ME) with andesitic composition are recorded only in granodiorite phase I and ... إقراء المزيد
