Abstract: Aphids are the cloning experts. They have, moreover, hundreds of millions of years’ experience of cloning, hundreds of millions of years in which evolution and natural selection have enabled them to overcome the problems and exploit all the advantages of clonal reproduction. . Colonies of thousands of individuals can appear on plants in a few days, as if by magic. This phenomenal rate of reproduction is only possible because no time or energy is wasted on sex. All the aphids in these colonies are female. Dispense with males and there is no need to expend time and energy on finding mates, courting, and the laying and incubation of eggs. Parthenogenesis ˗ the development of unfertilised eggs ˗ enables female aphids to give birth as soon as they are adult. Their progeny are born alive and kicking like human young, but nothing like so helpless, and what is more they are all female, ready in a matter of days to give birth themselves. An experiment was carried out in laboratory to study the same phenomenon in dusky veined aphid, Panaphis juglandis. Newly born nymphs were separated and put into separate clip cages individually. After 14-17 days they became alates and start giving birth to young ones which were all females. Studies on female fecundity revealed that mean fecundity of P. juglandis were 66.8 larvae /female.

Abstract; Urinary tract infection is a common clinical episode seen within the hospital and community setting but the prevalence level varies with aetiological agents and their resistant pattern. The retrospective study determined the prevalence of bacterial pathogens isolated from urinary tract infection and their antimicrobial sensitivity pattern. Bacteriological data of mid-stream urine samples collected from patients with suspected cases of urinary tract infection presented at the hospital were analyzed by standard bacterial methods. Of the 21,840 urine specimens analysed over the study period, 6314(28.9%) showed significant bacteruria and yielded positive bacteria growth. Gender distribution of 3552(56.3%) females and 2762(43.7%) males giving female to male ratio of 1.3:1.Gram-negative bacteria accounted for 4949(78.4%) of bacterial pathogens isolated compared to 1365(21.6%) gram-positive bacteria. Escherichia coli was the predominate pathogens, 2170(34.4%), followed by Staphylococcus aureus, 1230(19.5%), Klebsiella spp, 1179(18.7%). High frequency of occurrence of bacterial isolated was recorded within age-group 16-30(34.2%) and 31-50years(31.9%). A descending trend in the frequency of isolates was observed with bacterial isolates and patients age-group( E.coli, S.aureus and Klebsiella spp) with patients within age-group 0-5years to 16-30years, and ascending trend with Proteus spp and Pseudomonas spp within age-group 16-30 years to >50years. The antimicrobial sensitivity pattern of bacterial pathogens demonstrated similar pattern as reported studies of high sensitivity to quinolones, aminoglycosides, and macrolides and resistant to commonly prescribed and administered agents in the hospital and community setting. The study findings revealed the uropathogens and their sensitivity pattern, that could serve as a guide in empirical therapy of urinary tract infection in our hospital.

Abstract: Labor pain is natural. Increased cesarean rate, the major reason of which is fear of labor, is one of the problems of health systems. Today, much emphasis is put on promoting the use of non-pharmacological methods of pain relief. Accordingly, this study was conducted to investigate the effect of physiologic labor on pain intensity during active phase of labor in the mothers referring to the maternity hospitals of Zanjan in 2013. This study is a kind of clinical trial in which 200 eligible nulliparous women referring to the maternity hospitals of Zanjan were randomly selected and placed into two groups (physiologic labor and normal labor). The data collection tools included Visual Analogue Scale of Pain (VAS) and a questionnaire. The validity of the data collection tools was confirmed using content validity. The reliability of pain assessment tools was confirmed through an agreement between the assessors. The reliability of the satisfaction questionnaire was confirmed through qualifying domestic trust. Data analysis was done using SPSS, descriptive statistics, and inferential statistics such as the paired t-test, chi-square, Mann-Whitney, and Wilcoxon tests. According to the results, there was no significant difference between the two groups in terms of age, Body Mass Index (BMI), education level, gestational age, and employment status. The mean duration of active phase in the two control and experimental groups was not significantly different (p = 0.211). The pre-intervention pain intensity was not significantly different; however, the pain intensity at 3-4 cm dilation and 7-8 cm dilation in the physiologic labor group was significantly less than in the control group (p = 0.001).The findings show the effect of physiologic labor on pain intensity. The widespread use of physiologic labor could improve qualitative indicators for maternal health.

Abstract:Labor is one of the most critical and important services of healthcare systems in all communities. Like other services, labor services should be associated with the best outcome and minimum physical complications. This aim of the present study is to compare labor outcomes of physiological and normal delivery methods in mothers referred to Zanjan maternity hospitals in 2013.This is a clinical trial study conducted on 200 eligible nulliparous pregnant women referred to Zanjan maternity hospital in 2013. The mothers were selected randomly and divided into two groups of physiological labor and normal delivery. The data was collected using the General Health Questionnaire (GHQ) and a questionnaire. The content validity of the questionnaire was confirmed. The reliability of GHQ was confirmed through an agreement between assessors. The internal reliability of the Satisfaction Questionnaire was also confirmed. Data analysis was performed using descriptive and inferential statistics including the paired t-test, Chi-square and ANOVA with the help of SPSS.According to the results, there was no significant difference between the two groups in terms of age, BMI, educational level, gestational age and employment status. The cesarean rate decreased in the physiological labor as compared to the normal delivery (p=0.04). A significant difference was found between intervention and experimental groups in terms of the mean score of the maternal general health (p=0.001). However, no significant difference was found between the two groups in terms of the first and fifth minutes’ Apgar scores (p=0.341, p=0.233). The results indicated the impact of physiological labor on the cesarean rate and general maternal health. The widespread use of physiological labor will improve the qualitative indicators of maternal health.

Abstract: Due to the importance of water resources in arid and semi-arid areas and also environmental challenges caused by discharging of wastewater of municipal and agricultural activities, interests in the reuse of unusual water resources like drainage water is increasing. The objective of this study was investigating Sesame (Sesamum Indicum L.) response, irrigated by blending drainage water (DW) with river water (RW) in a warm and arid condition in south of Iran. A field study was conducted in commercial farms of Zeydun County, Khouzestan, Iran. Two sesame cultivars (Local and Line 6) were evaluated to compare grain yield, its components and biological production when irrigated with four salinity levels (blending ratios) [100%RW (ECw=2ds/m), 50% RW+50%DW (ECw=2.8 ds/m), 25%RW+75%DW (ECw=4.13 ds/m), 100%DW (ECw=5 ds/m)]. Results showed that among yield components only number of capsule per plant reduces significantly as salinity increased. Sesame Line 6 produced higher grain yield in comparison with Local under all salinity treatments with a maximum of 1500 kg/ha when irrigated with RW. Yet, relative yield of sesame Local was higher than Line 6, indicating higher salt tolerance in Local cultivar. Although all salinity levels had negative effect on sesame production, by accepting only 3-6 percent reduction in grain yield under blending ratio 50%RW+50%DW drainage water could effectively be reused for sesame production. Moreover, damaging environmental impacts of drainage water discharging could be diminished.

Abstract: Background: Nausea and vomiting are common gastrointestinal disorders in early pregnancy. Considering the unknown adverse effects of most drugs used to control pregnancy induced nausea and vomiting, alternative treatments such as vitamin therapy, herbal medicine, and acupuncture and pressure medicine have been suggested. We aimed to assess the effect of acupressure on nausea and vomiting during pregnancy in a sample of Iranian women. Methods: In this quasi-experimental study of 195 pregnant women with gestational age less than 16 weeks of pregnancy care clinic in Shiraz hospitals for 7 days were included in the study. They were randomly divided into three groups: acupressure, placebo and control group. In the first 3 days of the third group received no medication. For the second stage of the fourth day, with pressure on the p6 wristband acupressure group and the placebo group in both p6 wristbands with a button on the front of the pack. And the control group did not receive any intervention. Gathering data, Rhodes scale that was completed by the individual was important. Results: There was no difference between the 3 groups with respect to the number of child births, the number of children, mother’s age, or the gestational age before starting the treatment. In the treatment groups, symptoms of nausea and vomiting significantly decreased after starting the treatment. The severity of nausea as well as the frequency of vomiting reduced significantly after starting the treatment in treatment group 1 compared with the other two groups. Moreover, the severity of vomiting was significantly different in treatment group 1 after the treatment. Conclusion: Pressing the pericardium 6 point is effective in reducing the severity of nausea and the frequency of vomiting.

Abstract: Two species of aphids colonize walnut orchards in Kashmir valley, Walnut green aphid (Chromaphis juglandicola Kalt.) and Dusky veined aphid (Panaphis juglandis Goeze). P. juglandis colonizes the top side of the walnut leaf, establishing the characteristic colonies along the main nerve. This aphid is much larger than common walnut aphid, C.  juglandicola which feeds on lower surface of leaves. P. juglandis and C. juglandicola are potential pests of walnut orchards in Kashmir valley. Present study was carried out to know the natural enemies of walnut aphids in Kashmir valley and their population dynamics & bio-control potentiality vis-a-vis aphids. Two sites were selected falling in two major zones of the valley and monitoring was done following UC-IPM protocol for monitoring walnut aphids & natural enemies. Populations of these aphids are controlled at low by natural enemies in orchards of Kashmir valley. During present study, Syrphid fly larvae were the most important predators encountered in this study.

Abstract: The study was carried out in some secondary schools in the Federal Capital Territory, Abuja Nigeria. The secondary schools were chosen from Abuja Municipal, Bwari, Gwagwalada and Kuje Area Councils using multi random sampling method, 8 of the schools were day school while the other 8 were boarding schools. A total number of 144 questionnaires were administered to 72 boarding students and 72 day students. Among many information collected were personal characteristics of the students, assessment of students reading habit and the influence of students’ reading habit on their academic performance. Results and discussion were presented using frequency counts, percentages, Pearson correlation analysis and T-test were used to test the hypothesis. The study indicated that almost equal percentages SS I, II and III students in all the secondary schools were selected and they were mostly between the ages of 15-17 years. More of the boarding students read regularly because they have scheduled time for reading in their curriculum, they sometimes use and borrow library books. Day students read occasionally especially during examination as they were more involved in non-academic social chores. In their academic performances, more boarders were above average than the day students. However, t-test analysis showed that there was no significant difference between the academic performances of day and boarding students in secondary schools in Abuja, Nigeria. Most of the students affirmed that reading has positive influence on their academic performance. Environmental influence, parental and teachers influence, peer pressure and school curriculum were some of the factors militating against better reading habits. Parents and teachers alike are encouraged to train the mind of their wards/students towards reading and reduce their home and school chores.

Abstract: The author aims to examine critically the parties’ autonomy in Arbitration. Further, to see that whether the Arbitration law gives absolute autonomy to the parties or gives some restrictions on that. To what extent the party autonomy principle is acceptable. The party autonomy principle given in the Arbitration law is not absolute and which is controlled by the important mandatory provisions. However, the party autonomy principle is somewhere violating the principle of natural justice and public policy as well which are the fundamentals of the law of the land. The author has formulated the following questions and has tried to find out the answer- Whether the parties may agree on everything for Arbitration. What is the autonomy available to the parties during Arbitration proceedings? Whether there is any restriction on such autonomy or it is absolute. Whether principle of natural justice apply to the Arbitration proceeding. Whether giving party autonomy is against the public policy of the country.

Abstract Victims of rape under Indian Penal Code, 1860 are least supported than the accused, and the victims in other crimes by the government and in the present adversarial criminal administration and justice system in their rehabilitation and protection. In the current decade of victimological research, there is a substantial interest in the study of impact of crime on victims and ways to assist them. Assistance to victims of crime is of great significance because victims have suffered irreparable damages and harm as a result of crime. The problems of violent bodily crime victims and the impact of crime on them is varied and complex. Therefore, the agencies of the criminal justice system expected to be receptive to the compensatory needs of the victims of violent bodily crimes and address their issues sincerely and empathetically. Like in the United States, Europe and the other developed countries. Neither Equal treatment nor access to justice shall be denied to victims of crimes.

Abstract: Lack of training and readiness of mothers is the leading cause of increased medical interventions and hence maternal and fetal complications. Accordingly, this study aimed to investigate the impact of group education of mothers on the procedure of labor in mothers referred to medical centers in Zanjan in 2014. In this interventional and quasi-experimental study, 280 primipara pregnant women, who were referred to the medical centers of Zanjan in 2013-2014, were selected through stratified cluster sampling method and were randomly assigned in two groups of experimental and control. Eight sessions of 90-minute pregnancy readiness classes were held for the experimental group, while mothers in the control group were received the usual education. A questionnaire was used to collect data in two phases of pre-test and post-test, which then were analyzed using SPSS through chi square, Fischer, and t-test. According to the results obtained, both groups had no significant difference in terms of body mass index (BMI), educational level, gestational age, and employment status. In addition, the severity of pain had not a significant difference before the intervention; however, the severity of pain at dilatations 3-4 cm and 7-8 cm was significantly lower in the physiologic labor group than the control group (p=0.001). Moreover, the rate of selective cesarean section was lower in the case group than the control group (p=0.04). The findings revealed that group education during pregnancy can affect the severity of pain and the rate of selective cesarean section in mothers. Widespread holding of pregnancy readiness courses will improve the health quality indicators of mothers.

Abstract: This paper presents analytical investigations for evaluating the punching shear strengthening of RC slabs using Carbon Fiber Reinforcement Polymer (CFRP) sheets. In terms of load capacity and maximum displacement, Model code 2010 provided new equations to estimate the rotation of slabs. The equations are based on critical shear crack theory. In this study the results from FEM verified via experimental data were compared to the results from the equations. A total of four reinforced concrete slabs with and without CFRP laminates were modeled via finite elements (FE) method adopted by ANSYS 14. The results obtained from the FE analysis are compared with the experimental data and Model code Level II equations for slabs with different strengthening conditions. The comparisons are made for load-deflection curves at slab centre and punching shear strength. The results from finite element analysis were calculated at the same locations as the experimental investigation. The accuracy of the finite element models, assessed by comparison with the experimental results, appeared to be in good agreement. The developed methods are used for further interpolation of the data and more detailed investigation of the effects of different factors of influence.

Abstract— The radon Concentration and exhalation rates from samples of soil which were collected from the Shivalik foot hills of Haryana and Himachal Pradesh in India were experimentally measured using Canister technique. The study aims at assessing the contribution of soil in building materials in the form of bricks and for filling purpose in construction towards the total indoor radon exposure to the inhabitants of the study area. In this context, samples of soil were collected from different parts of the Shivalik foot hills of the two states. After processing, the samples were placed in plastic Canister and LR-115 type-II detectors were used to records the tracks of α-particles emitted by radon gas. After chemical etching process the tracks produced were counted and radon concentration & exhalation rates were calculated. The average level of radon concentration in soil samples from Haryana varies from 125453 Bq/m3 to 3082 34 Bq/m3, the average values of mass exhalation rate varies from 502 mBq/kg/hr to 1221 mBq/kg/hr and the average values of surface exhalation rate varies from 114449 mBq/m2/hr to 2811 31 mBq/m2/hr. Similarly, the average level of radon concentration in soil samples from Himachal Pradesh varies from 226584 Bq/m3 to 3464 224 Bq/m3, the average values of mass exhalation rate varies from 903 mBq/kg/hr to 1436 mBq/kg/hr and the average values of surface exhalation rate varies from 206677 mBq/m2/hr to 3159 205 mBq/m2/hr.

Abstract: Line x Tester analysis was used to identify the potential parents and their hybrids from a set of 12 crosses derived from three lines used as females LA-2661, LA-2662 and 017899 and four testers, including BL-1078, BL-1079, CLN-2413 and CLN-2418-A. Results showed that parents and F1 hybrids differed significantly for general combining ability and specific combining ability effects. The values of general combining ability (GCA) and specific combining ability (SCA) variances depicted non-additive and additive gene action with predominance of non-additive gene action in the genetic determination of all characters except fruit yield per plant. Parent lines LA-2662 and CLN-2418A provided the best general combining ability effects in more than one yield contributing traits. Specific combining ability effects, heterosis and heterobeltiosis in desired direction were recorded in two crosses viz. “LA-2662 CLN-2418A” and “LA-2662 BL-1078”. F1 hybrid “LA-2662 CLN-2418A” proved to be the best cross in overall performance and should be further exploited in breeding program for hybrid vigour and commercial utilization.

Abstract: Air and dust monitoring were conducted at representative El-Beida, Libya indoor/outdoor homes in order to identify and enumerate fungal common in indoor and outdoor environment. A total of fifteen home were assessed between April 2013 and March 2014, yielding a total of 270 samples from indoor homes, outdoor and dust samples for each month. Indoor samples had a maximum number of isolates fungi than outdoor, while dust samples contain the less number of isolates fungi. The large number of fungal colonies was recorded in site 3 followed site 5, in Autumn season followed by Summer then Spring, in February month followed by June then April and on MEA medium through the study.
