Degrees of Psychological Well-Being among Students of Palestinian Universities in Hebron Governorate

This study aims at investigating the levels of psychological well-being among Palestinian university students in Hebron District, and adapting Ryff's Psychological Well-being Scales to the Palestinian environment, The researchers applied the Ryff’s Psychlogical Well-being Scales on a simple random sample of (200) students located at three Palestinian universities (Hebron University, Al-Quds open University, & Polytechnic University). Validity was confirmed. Moreover, the reliability of the scale was confirmed by using Cronbach a coefficient. The study concluded that the degrees of Palestinian students' psychological wellbeing were moderate. In addition to that, the study found that there were differences in the degree of psychological well-being according to gender in favor of females, differences according to the type of specialization in favor of students in the human colleges, differences due to the economic level in favor of students with higher incomes, and differences due to the place of residence in favor of villagers students. Furthermore, the study found there were no differences in the average psychological well-being due to the sitting university. Finally, the study has come out a set of recommendations stemming from its results, such as the need to address welfare for Palestinians, especially in crowded cities, as well as the need to motivate university students in science faculties, and to reduce the degrees of tension induced by the difficult context in which Palestinians live

Addressing Health Disparities Among Homeless in Alachua County through Community-Based Participatory Research.

Introduction. In states such as Florida that did not expand Medicaid, a large number of economically disadvantaged individuals do not qualify for subsidies to buy health insurance through the Affordable Care Act (ACA) 2. This leaves the health needs of Florida’s homeless population largely unaddressed. Nearly 48.1% of Alachua County’s homeless population has disabling conditions 16. This confirms a pressing need to understand the homeless population\u27s healthcare needs, knowledge, and barriers in accessing healthcare. Methods. We used a Community-Based Participatory Research model in conducting health fairs and needs assessment surveys, incentivizing participation, and providing education about existing resources. The surveys were conducted at two homeless meal service sites and consisted of 22 questions regarding access to healthcare, utilization, and satisfaction. Health fairs consisted of blood pressure, blood glucose, and mental health screening. Patient participation was encouraged through games, prizes and food. Results. Of the population we surveyed, 100% have income levels below $11,490, therefore all uninsured fall into the ACA coverage gap. Those less than 65 years of age do not qualify for Medicare unless disabled. Some qualify for Medicaid as shown in tables. Fifty-eight percent were uninsured and did not get any treatment for their illnesses. Additionally, 67% had no knowledge of free local healthcare clinics. Discussion/Conclusion. The majority of this population falls into the ACA Coverage Gap, lacks knowledge about free community clinics, and inappropriately uses the ED. Future implications of this research involve advocacy to expand Medicaid in Florida and enroll those who are eligible for health insurance. Vital goals include outreach by free healthcare clinics to make healthcare more accessible, as well as building trust with the community through continued outreach initiatives. A community-Based Participatory Research Model is an effective tool to increasing collaboration among diverse members of the community in order to bring meaningful and positive change to the health of populations

Enhancement of Guidance System using Kalman Filter

The operation of Modern Guidance System may be separated into twocascaded functions1. Filtering of the noisy measurements obtained from the sensors and 2. Utilization ofthe estimated parameters to control the required acceleration.Guidance system is enhanced by using 3rd order Kalman filter to estimate theseparation distance and its derivatives that needed in optimal controller. Slant rangeand closing velocity is estimated using 2nd order Kalman filter and they also needed inestimation of time to go.The optimal guidance system is better than the proportional navigation, biasedproportional navigation, and the augmented proportional navigation system since itrequired simple achieved acceleration.Fading memory filter may be used to enhance the navigation system insteadof Kalman filter. It is simple in structure and need minimum time but less accuracythan the Kalman filter

Effectiveness of Flexible Pin Type Couplings

Matarneh M. I. Effectiveness of Flexible Pin Type Couplings / Mohammed I. Matarneh, Nabeel S. Gharaibeh, V. G. Artyukh // International Journal of Engineering Science and Innovative Technology (IJESIT). – Tamilnadu, 2015. – Vol. 4, Issue 2. – P. 1–7.The article shows that pin elastic couplings are not functionally elastic ones. Their endurance improvement is associated with their power intensity increase (stock of resilience). Another way is to replace elastic elements material (rubber) for more endurable and power-consuming polyurethane elastomers. Besides power capacity can be increased by elastic element mass expansion and the ration of the element mass to the coupling mass

mTORC2 signaling drives the development and progression of pancreatic cancer

mTOR signaling controls several critical cellular functions and is deregulated in many cancers, including pancreatic cancer. To date, most efforts have focused on inhibiting the mTORC1 complex. However, clinical trials of mTORC1 inhibitors in pancreatic cancer have failed, raising questions about this therapeutic approach. We employed a genetic approach to delete the obligate mTORC2 subunit Rictor and identified the critical times during which tumorigenesis requires mTORC2 signaling. Rictor deletion resulted in profoundly delayed tumorigenesis. Whereas previous studies showed most pancreatic tumors were insensitive to rapamycin, treatment with a dual mTORC1/2 inhibitor strongly suppressed tumorigenesis. In late-stage tumor-bearing mice, combined mTORC1/2 and PI3K inhibition significantly increased survival. Thus, targeting mTOR may be a potential therapeutic strategy in pancreatic cancer

TAGUCHI EXPERIMENTAL DESIGN AND ARTIFICIAL NEURAL NETWORK SOLUTION OF STUD ARC WELDING PROCESS

Stud arc welding has become one of the most important unit operations in the mechanical industries. The need to reduce the time from product discovery to market introduction is inevitable. Reducing of standard deviation of tensile strength with desirable tensile strength joint as a performance character was use to illustrate the design procedure. The effects of (welding time, welding current, stud material, stud design, sheet material, sheet thickness, sheet cleaning and preheating) were studied. Design of Experiment (DOE) is a structured and organized method to determine relationships between factors affecting a process and output of the process itself. In order to design the best formulation it is of course possible to use a trial and error approach but this is not an effective way. Systematic optimization techniques are always preferable. Tensile strength quality is one of the key factors in achieving good stud welding process performance. 225 samples of stud welding was tested. Computer aided design of experiment for the stud welding process based on the neural network artificial intelligence by Matlab V6.5 software was also explain. The ANN was designed to create precise relation between process parameters and response. The proposed ANN was a supervised multi-layer feed forward one hidden layer with 8 input (control process parameters), 16 hidden and 2 output (response variables) neurons. The learning rule was based on the Levenberg-Marquardt learning algorithm. The work of stud welding was performed at the engineering college laboratory, Baghdad University by using the DABOTEKSTUD welding machine, for 6 mm diameter stud. The sheet materials are (K14358 and K52355) according to (USN standards, and stud materials are (54NiCrMoS6 and 4OCrMnMoS8-6) according to (DIN standards). The eight control parameters (welding time, sheet thickness, sheet coating, welding current, stud design, stud material, preheat sheet and surface condition) were studied in the mixed L16 experiments Taguchi experimental orthogonal array, to determine the optimum solution conditions. The optimum condition was reached for the stud welding process tensile strength, where the researcher develops a special fixture for this purpose. The analysis of results contains testing sample under optimum condition, chemical composition of usage materials and micro structure of optimal condition sample. According to that: Practicality: the influence parameters that affect the stud welding process are welding time, which have a major effect on stud welding process, followed by sheet material and stud material. The reduction in standard deviation was approximately (30.06 per cent) and for the range was as approximately (29.39per cent). In the other side the increase in the tensile strength mean was as approximately (30.84 per cent). The influence parameters that affect the tensile strength stud welding process are: the factor welding time has a major effect on stud welding process, followed by factor C (sheet coating) and factor F (stud material)

Recurrent Breast Cancer Following Modified Radical Mastectomy and Risk Factors

Background: - Recurrent breast cancer is cancer that comes back following initial treatment. Risk factors of recurrence are lymph node involvement, larger tumor size, positive or close tumor margins, and lack of radiation treatment following lumpectomy, younger age and inflammatory breast cancer. Objective: Asses the rate of recurrence for early breast cancer in Iraqi female patients, in relation to certain risk factors. Patients and methods: A prospective study was conducted on 100 consecutive female patients, with stage I and stage II breast cancer treated by mastectomy and axillary dissection by the same team. Patients were assessed postoperatively every three months and recurrences were detected by physical examination and ultrasound of the bed of mastectomy and axilla. Statistical correlation using univariant analysis between recurrence rate and certain associated variables was done. Results: Recurrence rate was found to be 13%. It was more common among both young (20-29) years &the (40 – 49 ) years age groups which was 16.7%. Most of recurrences (61.6%) occurred (within 12_19 months) after surgical treatment. Statistically significant associations were found between recurrence and the latency period between first complaint and surgical management, the grade of the tumor, the size of primary tumor, and the number of lymph nodes involved. There was no statistically significant association between the type of adjuvant therapy and the incidence of local recurrence. Conclusions: the rate of recurrence after modified radical mastectomy is relatively high in our study. The same known risk factors related to the stage, grade and delay of treatment were detected, and close follow up especially at the first 20 months after surgery is recommended
