NONLINEAR BEHAVIOUR AND BEHAVIOR OF R.C. DEEP CANTILEVER BEAMS

This work theoretically investigates the nonlinear behaviour of reinforced concrete dee aimed topcantilever beams with concentrated loads at their free ends The study is aimed to in investigate the behaviour and respnse of such deep cantilever beams, and to help structural engineers to design and adopt appropriate reinforcement detailing of such elements. A complete review of literature on this subject is made.

Evaluating performance and reliability of AODV, ADV routing protocols in VANET environment using NCTUns 6.0 simulator

In this paper, we use NCTUns 6.0 to simulate this kind of networks ,because it is difficult to do that is the real world .In this paper, two routing protocols (AODV, ADV) are studied within many scenarios to achieve their performances and reliability using many metrics. We conclude that ADV routing protocol adapts quickly when the complexity of network and mobility of nodes increase. This is achieved by varying the size and frequency of routing updates.

Concerns Of Women With Unplanned Pregnancy

The aim of the study was to identify physical, psychological, socioeconomic and sexual concerns. This study was conducted in the antenatal clinic at children and obstetric hospital in Lattakia City. A convenient sample of 170 women with unplanned pregnancy attending the previously mentioned setting was included in the study. Questionnaire sheet was developed by researcher and used to collect the necessary data. The results of this study revealed that 41.18% of women have physical problems due to unplanned pregnancy, 74% of them have sad feeling and about 24%have depressed feeling. Also unplanned pregnancy cause social problems in 49% of women, financial problems in 62% of them. The results of this study also revealed that unplanned pregnancy affect sexual relationship between women and their partners. So we suggest comprehensive sexual education, availability of family planning services and increased access to a range of effective birth control methods. and must evaluate the incidence of unplanned pregnancy in our society and make proper action to reduce and prevent the occurrence of unplanned pregnancy.

Improving the performance of data transfer in the hybrid low-speed networks that are used in the near-real time operating establishments

The spread of the modern data transfer techniques, in modern industrial and agricultural applications, and service areas, leads to the need to transfer this data effectively and flexibly, within installations parts. This research aims to apply the hybrid mechanism, based on the use of ZigBee technology, and CAN Bus together to ensure the best performance, in accordance with the performance indicators required by the networks of these facilities, in near-real time operation. The study attempts to compare this mechanism with other mechanisms proposed in similar research. The proposed solution supports the use of a hybrid data transfer networks, based on the internetworking of CAN Bus networks, using a backbone based on wireless ZigBee technology. This solution proposes an appropriate structure for gateways between the hybrid parts of the network. The research has concluded that the proposed mechanism preference, compared with the proposed mechanisms in similar research, according to the standards of performance indicators, is suitable for this kind of networks, as it allows us to recommend the use of this mechanism in the service and industrial applications. The NS2 network simulator is used to evaluate and compare the obtained results.

Epidemics and complications of hysteroscopy

Hysteroscopy is a very important procedure to diagnose many lesions inside the uterus like: endometrial polyps, Leiomyomas , uterine malformations , adhesions in uterine endometrium. Hysteroscopy's benefit is shown in the way it provides us with direct vision to the uterus . Our Research is conducted around complications of hysteroscopy and its percentage . This research included 82 patients visited the department of obstetrics and gynecology with these complaints : infertility, abnormal uterine bleeding, menstrual disorders, recurrent abortions , Missing strings of IUDs . the complication rate of the hysteroscopy were ( 4.88% ) the most ommon complication was: bleeding ( 2.44% ) , it was the same rate of uterine perforation and acute abdominal pain ( 1.22% ) We never found any differences of complications rates According to different indications of hysteroscopy or according to the technique . As we found the Zero rate of vaginal delivery to the patient plays a role as a dangerous factor in the high rate of complications . Then , the Complication rate in our study are little, this explain that hysteroscopy is a safe procedure, and that push us to recommend to us it routinely which reduce the hospitalization time and the cost

Variation of some blood parameters during pregnancy in Awassi ewes

This research was done as a collaboration work between Tishreen University and the General Commission for Scientific Agricultural Research in Karahta research station for improvement of Shami goats and Der Al-Hajar station to set tables for normal values of some blood and chemical parameters in Awassi sheep during pregnancy to predict any nutrition or health disorders. Forty seven Awassi ewes in the same age (in the third season) were used for that purpose. Blood sample were collected from all ewes every month of the pregnancy period. Thealanine aminotransferase (ALT),the aspartate aminotransferase (AST), the alkaline phosphatase (ALP), the glucose (Glu) were analyzed. Results indicated the existence of significant changes (P<0.05) between the increase and decrease in all indicators studied throughout The study period, which shows the change in functional status of liver in conjunction with stage of pregnancy.The overall average of the effectiveness of enzymes (2.05-26.47), (32.65-181.40) and (11.17-79.76) U/l for each of the ALP, ALT and AST, respectively, and total concentration of glucose (37,50-95.20 mg/dl) throughout the study period.
