Structural elements and metamorphism controlling the late Pan-African Hammamat sediments at the Up-stream of Wadi El-Miyah, Central Eastern Desert, Egypt.

2018-10-03 09:07:32 Keywords Hammamat sediments, , Pan-African, W. El Miyah, , Eastern Desert, Egypt.,
Structural elements and metamorphism controlling the late Pan-African Hammamat sediments at the Up-stream of Wadi El-Miyah, Central Eastern Desert, Egypt.
The Hammamat sediments at the Upper stream of Wadi El Miyah, Central Eastern desert of Egypt, occupy two isolated basins separated from each other by metavolcanics associated with their equivalent volcanoclastics and intruded by the younger granites. In the Eastern basin, the Hammamat succession rests unconformably over the metavolcanics, with basal conglomerates up to 5 m thick, and four distinct ... Read more

Subduction-related Wadi Dabr metagabbro-diorite complex, intrusive gabbros and the enclosed opaques, Central Eastern Desert, Egypt.

2018-10-03 09:15:52 Keywords W.Dabr, subduction-related, , Eastern Desert, Egypt, , Metagabbro-diorite complex,
Subduction-related Wadi Dabr metagabbro-diorite complex, intrusive gabbros and the enclosed opaques, Central Eastern Desert, Egypt.
The Dabr metagabbro-quartz diorite intrusion (DMQD), commonly described as metagabbro-diorite complex, occurring along Wadi Dabr, forms an elongated mass intruded into the metavolcanics and associated pyroclastics. It is intruded by younger gabbro (Ygb) and younger granites. The DMQD comprises metagabbro, diorites , quartz diorite and appinites.. Variation diagrams of the DMQD suggest fractional crystallization by separation of pyroxene followed by ... Read more

Design, Synthesis and Antibacterial Evaluation of some new 3,5-Diphenylcyclohex-2-en-1-one Derivatives

2018-09-24 17:15:50 Keywords , Diphenylcyclohexene Chromen,
Design, Synthesis and Antibacterial Evaluation of some new 3,5-Diphenylcyclohex-2-en-1-one Derivatives
The moiety of cyclohexene has been showed highly antibacterial activity. New compounds were synthesized from diphenylcyclohexenone via reaction with a variety of reagents to afford branched chain of 1,3-diphenylcyclohexene or fused heterocyclic systems including pyrazole, chromen and pyrrole derivatives. Cyclic ketoketene _s,s_-acetal can be prepared by reaction with CS2/MeI under PTC conditions which in turn used as starting material for ... Read more

Distribution and morphology of defensive acid-secreting glands in Nudipleura (Gastropoda: Heterobranchia), with an emphasis on Pleurobranchomorpha.

2018-09-24 07:10:28 Keywords Heterobranchia, Pleurobranchom, Pleurobranchomorpha, , acid glands., Histology, comparative morphology, Heterobranchia, Pleurobranchomorpha, Euctenidiacea,
Distribution and morphology of defensive acid-secreting glands in Nudipleura (Gastropoda: Heterobranchia), with an emphasis on Pleurobranchomorpha.
Secretion of acidic substances with defence and repellent properties is known in several metazoan taxa, including Gastropoda. Here we investigate and compare defensive acid-secreting cell types of various genera within the heterobranch taxon Pleurobranchomorpha by analysing the sizes and distribution of the secretory epithelial cells and subepithelial glands of the epidermis. Additionally, we investigate the median buccal gland (MBG), which ... Read more

INVESTIGATING THE EFFECTS OF CEMENT AND CEMENT KILN DUST AS A FILLER ON THE MECHANICAL PROPERTIES OF COLD BITUMINOUS EMULSION MIXTURES

2018-09-25 00:12:06 Keywords cold bituminous emulsion, cement kiln dust, SEM, , ITSM, fatigue, resistance to rutting,
INVESTIGATING THE EFFECTS OF CEMENT AND CEMENT KILN DUST AS A FILLER ON THE MECHANICAL PROPERTIES OF COLD BITUMINOUS EMULSION MIXTURES
The application of cold mixes is lagging behind in the research field, which is quite obvious in a developing country. Furthermore, cold mixes have more economic and environmental advantages than hot mixes. This is the principal motivation for the present research, which aims to improve the mechanical properties of cold mix asphalt. Ordinary Portland cement (OPC) and cement kiln dust ... Read more

Otorhinolaryngological manifestations of pulmonary tuberculosis

2018-09-25 09:27:24 Keywords , ORL involvement, Pulmonary TB,
Otorhinolaryngological manifestations of pulmonary tuberculosis
Tuberculosis (TB) is an important re-emerging disease with increasing global morbidity and mortality. Pulmonary involvement is the commonest form of TB and otorhinolaryngologic (ORL) manifestations are common presentations in patients with pulmonary TB (PTB). To evaluate the prevalence of ORL lesions and their effects in these patients this study was prospectively designed. One hundred consecutive patients with newly diagnosed PTB ... Read more

Epidermoid/Dermoid Cysts in Head and Neck Region: Diagnosis and Management
Objective: to highlight the essential points in diagnosis and management of head and neck epidermoid/dermoid cysts. Design: A retrospective design was followed for the study. Methods: The study included all patients with epidermoid/dermoid cysts presented to the ENT Department over a 7 year's period. Diagnosis was based on history taking, full clinical examination, ultrasonographic examination of the lesion. All cases ... Read more

Chemical Peeling and Microdermabrasion of the Skin:Comparative Immuno-histological and Ultrastructural Studies

Chemical Peeling and Microdermabrasion of the Skin:Comparative Immuno-histological and Ultrastructural Studies
Comparative immunohistological and ultrastructural studies were performed on specimens taken before and after the application of chemical peels (Jessner’s solution and glycolic acid) and microdermabrasion to the clinically normal facial skin of the post-auricular region. Skin treated with chemical peels showed the immunohistological features of wound healing. Beside these, ultrastructural changes of cell injury were observed. These morphological changes were ...
