Study Design: This is a descriptive-analytic study. Methods: The population of this study is women referred to health centers in Kermanshah with the health caregivers in 2016. Research samples as the two-stage cluster sampling were selected and studied according to the goals set. For data analysis, SPSS version 16 and descriptive statistics and analytical (Pearson correlation coefficient) were used. Results: One hundred seventy of each group, samples participated in this study. The level of knowledge and practice in the health caregivers was 49.60 and 25.57, and in the referred women was, 50.40 and 22.21, which was statistically significant (P =< .001). Only 10.34% of the health caregivers and 8.70% of the referred women performed breast self-examination tests and only in 5.90% of the health caregivers and 1.70% of the referred women" regular and monthly. 46.50% of the health caregivers performed mammography which only 1.20% each year and in the group of referred women was 34.10%, which was only 24.80% annually. Conclusions: The findings of this study indicate the bad to average levels of knowledge and practice of women participating in this study. Therefore, in order to increase the knowledge and practice of women about the prevention of breast cancer, the development of screening, educational, and motivational programs to increase the participation of women in these programs, especially in the healthcare personnel who act as health messengers and in contact with other clients; highly recommended
Trends, Issues and Practice in Geriatric Nursing Care
No full textGeriatric nursing is a field of medicine and hospice care that deal with elderly people. Geriatric nurses are some of the most important professional in the field of nursing, as they provide different cares for different illness in elderly patients with unique needs. Because of their fragile health issue they need special health care. Working as a geriatric nurse is often very grafting, remarkable and rewarding personally. However, it takes a special type of nurse to work in this field, and the work can also be more frustrating, complication or disheartening at times as well. As a nurse, we should always remember that all the elderly people were different from each other, while some elderly patients are somewhat content or even happy or other might be having pain, sadness, scared or even angriness that their health is failing day by day this is happen due to lack of independence and isolation from their families loved ones. Handling them with care and also with love and affection is nurse responsibilities to make sure, they are in right place which will help their mentally and reduce their negativity feeling. Geriatric nursing is committed to providing timely health information on new and innovative programs and practices in clinical, community as well as home care and administration. It also reported clinical findings that are applicable to practice
Design and Analysis of Centrifugal Impeller
Full text linkCentrifugal pumps are used widely in different industries for various industrial purposes. Since performance of pump is affected by vibrations and depends on the blade inlet or outlet angle. The performance of the centrifugal pumps can be improved by alternating the geometric characteristics of impeller in the pumps. Centrifugal pump performance mainly depends upon blade exit angle. The vibration is mainly caused by blade exit angle. The rotating of the blade is based on the natural frequency and mode shapes. The impeller chosen for the study was a single- entry impeller with radial vanes. Using Creo 4.0 and ANSYS Workbench software the modeling and simulation of the impeller have been carried out. The respective frequencies and corresponding mode shapes impeller were measured by using eigenvalues and eigenvectors respectively. The results showed that the varying impeller blade exit angle had significant effect on natural frequency of the impeller

Effectiveness of Rain Water Harvesting for change of trends in Aquifer behaviour
No full textRain water harvesting (RWH) and Artificial recharge techniques are low cost solutions to water crisis. In cities, due to increasing urbanization, rain water can be harvested and recharged to the ground water artificially. This paper presents a study of effectiveness of RWH interms of change of trends in aquifer behaviour. Chennai,formely Madras, City, capital of Tamilnadu Sate is selected as the study area since major RWH structures has taken constructed during 2001-2003 because of Government legislation. Preliminary analysis of rainfall and groundwater levels were carried with respect to space and time to understand the trends. Water table contours were drawn using the Arc GIS.9.2 software. “Groundwater Estimation Committee (GEC)” rules of Government of India were used for estimation the change in storage during pre and post RWH periods, which are found to be 1.76 Mm3 & 32.77 Mm3 respectively. It is concluded that the implementation of RWH has improved the groundwater storage though the rainfall in the study area is decreased and the extraction is increased due to raise in population
INFLUENCE OF SLOPING GROUND ON THE SEISMIC ANALYSIS
No full textSeismic investigation is the computation of the reaction of a structure to quakes. It is a piece of the procedure of auxiliary plan, seismic tremor building or basic evaluation and retrofit in districts where quakes are common. The aim of this paper to study the response of RC structure on slopping ground. To evaluate the response of building by using linear analysis and non linear analysis. The analysis will be carried out on SAP2000 with help of guidelines following code I.S1893:2002 (part I), FEMA 356. The seismic reaction on slope ground is quite dissimilar as compare to seismic reaction on simple ground. In Reinforce concrete structure design we will not take the effect of infill wall on structure at the time of earthquake. In addition to this infill walls have a considerable strength and inflexibility and they have main effect on the seismic reply of the structural system. Requirement of analysis the seismic response of Reinforced Concrete building on inclined ground because require of timely revision of codes of practice and standards. Mount buildings are dissimilar from those in flat surface; they are very unequal and asymmetrical in horizontal and vertical planes, and torsionally coupled. Due to the diverse configurations of building in mountainous areas, these buildings become highly irregular and asymmetric, due to difference in mass and rigidity distributions on dissimilar perpendicular axis at each floor. Such buildings are seismically level areas makes them showing to greater shears and torsion as compare to conservative construction
