Calculation of the Scattering Amplitude of A Nucleus in the Presence of the Yukawa Potential

The scattering amplitudes are obtained from the phase shifts for a spherically symmetric potential using the D-dimensional Schrödinger equation and the partial wave method. Plots show that the real and imaginary parts of the scattering amplitude are almost similar behavior

The investigation of transcendental meditation effects on pain and length of active phase of labor in primiparous women

Background & Aim: Labor pain is one of the most intensive type of pain and regarding its control still is a problem in many countries. The aim of this study is to investigate the effect of transcendental meditation on pain and length of active phase of labor in primiparous women. Methods & Materials: This study configured as a semi-experimental clinical trial work. Samples was selected by convenient sampling method and contained as 90 primiparous women’s (45 case and 45 control) whom refer to clinic and delivery room in Fatemieh Hospital of Hamadan. Samples were divided into two random group and accomplished to experience and observation transcendental meditation method used for training pregnant woman within third trimester of pregnancy (28th-30th week) and performed by them for two time a day during 10 to 15 minutes. The case and control groups were matched according their age, education and occupation case and control group were confined to bed when they were in the beginning of active phase (3-4 cm of dilatation). Collecting of data, questionnaire information of biophysical and other equipment for recording biophysical developments and other McGill instrument was used to record severity of pain. Reliability and validity instrument in the prior researches have been test. The length of active phase was measured over maternal and recorded. Results: The results of this study showed that there is significant differences in the level of pain at the beginning of first, second and third hour of active phase of labor in case and control group (p<0.001). Also, the length of active phase of labor showed significant difference between case and control group (p<0.001). Although, the body temperature and systolic blood pressure in two group showed no significant differences but there was meaningful differences in diastolic blood pressure (p<0.029), however this differences was in normal range. Regard to rate of breathing significant differences has been shown in case and control group (p<0.006). Conclusion: Transcendental meditation in participated samples over this research among the mothers agony experience group has less pain within all active phase hours

Seroepidemiological study of leptospirosis in Ghaemshahr Mazandaran province-Iran, Sept-Oct 2004

Background and purpose: Leptospirosis is a zoonotic spirochetal disease caused by coming into contact with water or soil contaminated with urine of the infected animals such as sheep, hours, cow, rat and etc. Farmers, animal husbands, veterinarians and those practicing aqua sport are at risk.Materials and Methods: This study was undertaken in 13 villages of Ghaemshahr City (September 2004) in which because of previous epidemiological observation the probability of this disease was high. Study was descriptive cross sectional with randomized case selection. Five ml of venous blood was taken from each case and tested using an ELISA method. Information about age, sex, job, area of living, symptoms such as fever, headache, mialgia, diarrhea, nausea during this or past summer were gathered.Results: Serological data showed that prevalence of leptospirosis was 29.4 % .There is no relation between sex and positive serological results (54.8% women & 54.18% men).Conclusion: Leptospirosis in studied area is epidemic and due to its high morbidity, mortality and economical impact,heath education to people would help to control the disease and chemoprophylaxis can also be used
