Creating Bill of Students Rights and Responsibilities at Helwan University
University is open to all persons who are qualified according to its admission standards unless resource limitations results in the closure of academic programs in which applicants have expressed interest. Students' rights refers to a set of rights, responsibilities, and duties under which a student can seek and receive all educational service, encompass legal and ethical issues in the academic institutions and student relationship, including a student's right to privacy and to equal evaluation. So this study aimed to creating bill of students' rights and responsibilities at Helwan University. Operational design was carried out in the twenty faculties at Helwan University; Quota sampling used a sampling method for gathering representative data from two categories first category was university students consisted of 1200 students enrolled in four levels at academic year 2013 / 2014 representative 60 students from every faculty from twenty faculties studied setting at Helwan University. Second category was academic staff consisted of 40 academic staff 20 were professors and 20 were assistant professors 2 from every faculty study setting at Helwan University. Self-administered questionnaire used for the data collection consisted of two parts; the first part is socio-demographic characteristics served to collect information about age, gender, levels and educational qualification. The second part was 98 items divided into four components about academic, non-academic rights and responsibilities. The researchers developed a bill of students' rights and responsibilities based on students' opinions, and second part is an opinionnaire sheet used for the validity of the created students' bill of rights and responsibilities. The response was 3-point Likert scale from "strongly agree" to" disagree." The results are evident that; Mean Score in total agreements upon students' rights were ''1.57 ± 0.37''. While, Mean Score in total agreement upon students' responsibilities were ''1.53 ± 0.41''. There is a highly statistically significant positive correlation between students' scores of agreement upon rights and responsibilities (p<0.01). In conclusion, there is a highly statistical significant positive correlation between students' score of agreement upon rights and responsibilities. There was negative statistically significant correlations were revealed between students' scores of academic responsibilities and non- academic responsibilities with levels. It is concluded that the proposed students' bill of rights was valid, and effective in almost all items related to academic and non-academic students' rights and responsibilities were highest score; this reflects the importance of increasing students' awareness of their rights as well as their responsibilities and involves the students' rights to be informed about all aspects of the learning process and their involvement in the quality of education. The study recommends disseminating this created bill of rights and responsibilities in all universities at the Ministry of Higher Education in Egypt.Keywords: bill of rights, quota sampling, responsibilities, rights, and students bill of rights
Bulletproof Vests/shields Prepared From Composite Material Based On Strong Polyamide Fibers And Epoxy Resin
Fiber Reinforced Plastics (FRP) have arisen as a main class of tactual materials having high strength and light weight implemented in a large scale of different applications. This study performs a comparison between the enhanced propidines of Kevlar 49 fiber and Twaron CT 704 reinforced with epoxy resin to obtain an efficient, light weight and slim body m o r capable of resisting high speed projectiles (9 mm bullets). Reinforcing the fabrics adds extra strength to the fabrics instead of using several unreinforced fabrics which increases the weight thickness and the cost of the final product. The response of the prepared composite material based on the two different fibers was studied by using a test barrel for the penetration test. In addition. indentation test is also au lied to compare between the mechanical properties of both laminates and determine which fabric is better for life protection application. The final results showed that using the technique of reinforcing the fabrics specially Twaron is much better where the final bulletproof shield has a smaller number of layers and was found lighter by 40% than those made by Kevlar
Developing and Validating of a Managerial Procedures Manual for Head Nurses
The managerial skills are a set of behaviors based on knowledge that can be learned through procedure. Procedures are descriptions of how to carry out an activity. Procedures manual is essential to ensure consistency and quality in products and services. The aim of this study was to develop and validate a managerial procedure manual for head nurses at Ain-shams University Hospital. The study was conducted in Ain Shams University Hospital using operational design. It included a group of 78 head nurses for assessment and a jury group consisting of 16 faculty members of Nursing Administration and 8 nursing directors and assistants. Data were collected using a head nurses' self-administered questionnaire and opinionnaire form for the jury group. The researchers discussed the idea of the study with representatives of the hospital administration to reach to an agreement regarding the importance of the proposed manual and its content, then assessed head nurses’ view of the importance of a managerial manual. The results showed that 25.6% of the head nurses did not know about the presence of a manual for managerial nursing procedures, 96.2% expressed the need for such manual, and 70.7% reported having faced problems due to lack of such manual. Based on analysis of the data the researchers developed the manual that was validated by the jury group, and distributed to head nurses after approval of the hospital administration. The hospital administration participated in all steps of the development of the manual, and adopted its use in the setting. The effectiveness of the manual in reducing head nurses' stress related to managerial problems needs to be assessed after a few months of implementation. Key words: Head nurse, Manual, Managerial skills and Managerial procedure
High-Strain-Rate Compression Testing of Ice
In the present study a modified split Hopkinson pressure bar (SHPB) was employed to study the effect of strain rate on the dynamic material response of ice. Disk-shaped ice specimens with flat, parallel end faces were either provided by Dartmouth College (Hanover, NH) or grown at Case Western Reserve University (Cleveland, OH). The SHPB was adapted to perform tests at high strain rates in the range 60 to 1400/s at test temperatures of -10 and -30 C. Experimental results showed that the strength of ice increases with increasing strain rates and this occurs over a change in strain rate of five orders of magnitude. Under these strain rate conditions the ice microstructure has a slight influence on the strength, but it is much less than the influence it has under quasi-static loading conditions. End constraint and frictional effects do not influence the compression tests like they do at slower strain rates, and therefore the diameter/thickness ratio of the samples is not as critical. The strength of ice at high strain rates was found to increase with decreasing test temperatures. Ice has been identified as a potential source of debris to impact the shuttle; data presented in this report can be used to validate and/or develop material models for ice impact analyses for shuttle Return to Flight efforts
Impact of a Designed Nursing Intervention Protocol about Preoperative Liver transplantation Care on Patients’ Outcomes at A University Hospital in Egypt
Background: Literature review cited that, Liver transplantation is now considered as the gold standard for treatment of patients with end-stage liver diseases and early liver tumors in cirrhotic livers. Patient education is vital to the safety and success of a transplant. Aim: the aim is to assess the impact of a designed nursing intervention protocol about preoperative liver transplantation care on patient’s outcomes as indicated by: patients` knowledge & practice mean scores, and complications developed. To fulfill the aim of this study, the following hypothesis was formulated: patients undergoing liver transplantation who will be exposed to the designed nursing intervention protocol about preoperative liver transplantation care will show better outcomes. Material and Methods: A convenient sample of 14 adult male and female patients admitted to Liver Transplant Unit at El Manial University Hospital were included, three of them were died with an attrition rate of 21.4%. Four tools were formulated to collect data pertinent to the study. 1- Sociodemographic and medical data sheet; 2- Pre/Post knowledge assessment questionnaire sheet, 3- Observational checklists, & 4- Complications assessment sheet. Structured interview, reviewing medical records, direct observation and physical examination were utilized for data collection. Results: a significant statistical difference was found in relation to the total and subtotal mean knowledge and practice scores during different assessment periods with P values (0.00 for both); as well, 45.5 % of patients developed respiratory complications (pleural effusion) compared to 53.8 % of their correspondence who developed respiratory complications (pleural effusion, chest infection, and others), in addition, 9.1% of the studied subjects developed rejection, and ascites as compared to (1.9 %, 5.7%) of their correspondence over the last consecutive three years respectively. Conclusion: Liver transplantation patients showed a positive improvement in their knowledge and practice in relation to breathing, coughing, & using respirometer exercises and range of motion. Replication of this study on a larger sample selected from different geographical areas is highly recommended.

Evaluation Of Facial Soft Tissue Changes In Excessive Gingival Display Cases After Le Forte I Maxillary Impaction Surgery Using 3D Facial Surface Laser Scanner
Introduction: Facial soft tissue changes in relation to hard tissue movements after orthognathic surgery cases is always of concern to patients , surgical and orthodontics teams. The aim of the present study was to assess facial soft tissue changes and stability using 3D facial laser scanner after orthognathic surgery Le Forte I maxillary impaction in excessive gingival display patients. Methods: The subjects consisted of 12 patients with skeletal vertical maxillary excess (VME) causing an aesthetic concern to the patients in the form of “Gummy smile”, who underwent LeFort I osteotomy with maxillary impaction, Three-dimensional images of the patients were acquired with a 3D laser scanner preoperatively and postoperatively. The changes in facial soft tissue were detected using a colour coded map for analysis. Results: Significant change was recorded in the upper lip, alar base, nasolabial fold and nasal tip areas, without specification of this change in direction. Conclusions: The 3D images captured using the laser scanner in this study can be a useful tool for communication with both patients and professionals but cannot be relied upon solely for accurate analysis of the facial soft tissue changes. The colour coded map analysis cannot be relied upon solely as a method of analysis as it lacks an important aspect of the change which is the direction
Twin pregnancy with complete hydatidiform mole and coexisting fetus following ovulation induction with a non-prescribed clomiphene citrate regimen: a case report
<p>Abstract</p> <p>Introduction</p> <p>Twin pregnancy with complete hydatidiform mole represents a very rare obstetric problem. Management of such cases is always problematic because the possibility of fetal survival should always be weighed against the risk of complications of molar pregnancy.</p> <p>Case presentation</p> <p>A 34-year-old Caucasian woman presented to our center with mild vaginal bleeding. Our patient was 16 weeks pregnant after a seven-year period of primary infertility. She became pregnant following a non-prescribed regimen of clomiphene citrate extending from the second day to the 13th day of her last cycle. A transabdominal ultrasound examination revealed a twin pregnancy with complete hydatidiform mole and a coexisting fetus. Serum β human chorionic gonadotropin was falsely low as identified by serial dilution of the sample (the 'hook effect'). Our patient refused termination of pregnancy and she was hospitalized for strict observation and follow-up. Unfortunately, she developed an attack of severe vaginal bleeding and a hysterotomy was performed. The fetus died shortly after birth.</p> <p>Conclusions</p> <p>Twin pregnancy with complete hydatidiform mole represents a matter of controversy. We suggest that conservation should always be considered whenever tertiary care services and strict observation are available.</p

Effects of hospital facilities on patient outcomes after cancer surgery: an international, prospective, observational study
Background Early death after cancer surgery is higher in low-income and middle-income countries (LMICs) compared with in high-income countries, yet the impact of facility characteristics on early postoperative outcomes is unknown. The aim of this study was to examine the association between hospital infrastructure, resource availability, and processes on early outcomes after cancer surgery worldwide.Methods A multimethods analysis was performed as part of the GlobalSurg 3 study-a multicentre, international, prospective cohort study of patients who had surgery for breast, colorectal, or gastric cancer. The primary outcomes were 30-day mortality and 30-day major complication rates. Potentially beneficial hospital facilities were identified by variable selection to select those associated with 30-day mortality. Adjusted outcomes were determined using generalised estimating equations to account for patient characteristics and country-income group, with population stratification by hospital.Findings Between April 1, 2018, and April 23, 2019, facility-level data were collected for 9685 patients across 238 hospitals in 66 countries (91 hospitals in 20 high-income countries; 57 hospitals in 19 upper-middle-income countries; and 90 hospitals in 27 low-income to lower-middle-income countries). The availability of five hospital facilities was inversely associated with mortality: ultrasound, CT scanner, critical care unit, opioid analgesia, and oncologist. After adjustment for case-mix and country income group, hospitals with three or fewer of these facilities (62 hospitals, 1294 patients) had higher mortality compared with those with four or five (adjusted odds ratio [OR] 3.85 [95% CI 2.58-5.75]; p<0.0001), with excess mortality predominantly explained by a limited capacity to rescue following the development of major complications (63.0% vs 82.7%; OR 0.35 [0.23-0.53]; p<0.0001). Across LMICs, improvements in hospital facilities would prevent one to three deaths for every 100 patients undergoing surgery for cancer.Interpretation Hospitals with higher levels of infrastructure and resources have better outcomes after cancer surgery, independent of country income. Without urgent strengthening of hospital infrastructure and resources, the reductions in cancer-associated mortality associated with improved access will not be realised
Modeling of High-Strain-Rate Deformation, Fracture, and Impact Behavior of Advanced Gas Turbine Engine Materials at Low and Elevated Temperatures
Gamma titanium aluminides have received considerable attention over the last decade. These alloys are known to have low density, good high temperature strength retention, and good oxidation and corrosion resistance. However, poor ductility and low fracture toughness have been the key limiting factors in the full utilization of these alloys. More recently, Gamma-met PX has been developed by GKSS, Germany. These alloys have been observed to have superior strengths at elevated temperatures and quasi-static deformation rates and good oxidation resistance at elevated temperatures when compared with other gamma titanium aluminides. The present paper discusses results of a study to understand dynamic response of gamma-met PX in uniaxial compression. The experiments were conducted by using a modified split Hopkinson pressure bar between room temperature and 900 C and strain rates of up to 3500 per second. The Gamma met PX alloy showed superior strength when compared to nickel based superalloys and other gamma titanium aluminides at all test temperatures. It also showed strain and strain-rate hardening at all levels of strain rates and temperatures and without yield anomaly up to 900 C. After approximately 600 C, thermal softening is observed at all strain rates with the rate of thermal softening increasing dramatically between 800 and 900 C. However, these flow stress levels are comparatively higher in Gamma met PX than those observed for other TiAl alloys
