Spectroscopic and Optoelectronic Properties of Hydrogenated Amorphous Silicon-Chalcogen Alloys

Hydrogenated amorphous silicon-chalcogen alloy thin films have been the subject of growing interest during the past two decades. Thin films of these alloys are usually prepared by the decomposition of SiH4 and H2S or H2Se gas mixtures in a radiofrequency plasma glow discharge at a substrate temperature of 250°C. The alloy composition is varied by changing the gas volume ratio RV = [chalcogen/silane]. Infrared spectroscopy is used to explore the bonding structure of the alloy. The material exhibits hydrogen-induced bands, normally observed in a-Si:H spectra and other chalcogen-induced bands resulting from bonding chalcogen atoms with hydrogen and silicon. Analysis of the vibrational spectra of this material reveals the presence of significant levels of Si-chalcogen-SiHn configurations. Optical and electrical measurements show that increasing the chalcogen content results in an increase of the optical (Tauc) gap and a decrease in dark conductivity and photoconductivity. Subgap absorption measurements are employed to probe the Urbach energy and defect density. Upon increasing the chalcogen content, a broadening of band tails and an increase in defect density is observed. These results are shown to be consistent with photoluminescence measurements carried out on these materials

Stress intensity factors for near surface cracks by boundary collocation

A boundary collocation scheme based on Wilson solution for an internal crack was developed for use in half fringe photoelastic analysis of mixed mode SIFs. The scheme was used to obtain the stress intensity factors for a number of near boundary cracks of different angles and different distances to the surface. The influence of both the crack angle and the crack tip distance to crack length ratio on the SIFs were studied

Determination of Advanced Oxidation Protein Products, E3 SUMO-Protein Ligase NSE2[NSMCE2], as a Marker to Predict Child Acute Lymphoblastic Leukemia

Acute lymphoblastic leukemia (ALL) is a cancer of the blood and bone marrow (spongy tissue in the center of bone). In ALL, too many bone marrow stem cells develop into a type of white blood cell called lymphocytes. These abnormal lymphocytes are not able to fight infection very well. The aim of this study was to investigate possible links between E3 SUMO-Protein Ligase NSE2 [NSMCE2] and increase DNA damage in the childhood patients with Acute lymphoblastic leukemia (ALL).

Management outcomes of ectopic pregnancy depending on different treatment modalities: a cohort study

Background: Ectopic pregnancy is the most common cause of maternal morbidity and mortality during the first trimester of pregnancy. The present study aimed to review and evaluate the management outcomes of ectopic pregnancy in Damascus University Maternity Hospital, Syria.Methods: A retrospective cohort study was performed on women referring to Damascus University Hospital of Obstetrics and Gynecology (OBGYN) for ectopic pregnancy. Patients were assigned into groups by method of treatment: expectant management (Group 1), single-dose methotrexate regimen (Group 2), two-dose methotrexate regimen (Group 3), and surgical intervention (Group 4). Parameters assessed were risk factors for ectopic pregnancies, transvaginal ultrasonography findings, serum human chorionic gonadotropin (hCG) levels on Days 0, 4, 7, and types of surgical intervention in women that underwent any surgical intervention. A treatment modality was considered successful when hCG levels declined to less than 5 mIU/L without further administration of methotrexate dose or need for surgery.Results: Seventy-seven women with ectopic pregnancy were admitted to the hospital during the study period. Groups 1, 2, 3, and 4 constituted 20.8%, 13.0%, 6.5% and 59.7% of the patients respectively. The most common encountered risk factors for ectopic pregnancy in the patients were history of previous intra-abdominal or pelvic surgery (57.1%) and history of miscarriage (41.6%). A statistically significant difference in the serum hCG concentrations measured on day 0, day 4, and day 7 were observed between the groups.Conclusions: The success rate in ectopic pregnancy treatment was 56.25% for the expectant management, 70% for the single-dose methotrexate regimen, and 40% for two-dose methotrexate regimen

Representations of Integration in the Drawings of Asim Abdel Amir
