Macrolophus caliginosus (Hemiptera: Miridae) is a zoophytophagous predator widely used in integrated pest management programs in both greenhouse and open-field . Mass rearing of Macrolophus caliginosus is greatly dependent on Ephestia kuehniella Zeller (Lepidoptera: Pyralidae) eggs as food source. Moreover, the addition of this factitious prey after the inoculative releases of Macrolophus caliginosus under field conditions is recommended to facilitate establishment of this mirid. However, E. kuehniella eggs are expensive and availability is limited. One possible strategy to reduce the amount of E. kuehniella eggs needed is the provision of sugar.This study was conducted during the period between May and November in 2014 in the labs of the Lattakia center of rearing bio enemis. In this work, the effect of sucrose as nutritional supplement on selected life-history traits of M.caligenosus was studied. The addition of sucrose (100 g/l) ad libitum to a diet of E. kuehniella eggs significantly increased the progeny of Macrolophus caliginosus and did not affect survival of nymphs nor developmental time. Moreover, addition of sucrose significantly reduced the number of E. kuehniella eggs consumed. These results may have practical implications of interest in mass rearing systems of M.caliginosus and its management in fields and greenhouses as a part of integrated control programs.

In spite of all the advances in health care and medical technology, provision of quality health care to cancer patients remains one of the major challenges that health care professionals have to face in the next years. this study was conducted to assess the effect of nursing care on breast cancer patients quality of life at homes. by using quazi-experimental design 80 breast cancer patients were selected (40 experimental group ,40 control group) receiving chemotherapy recently. Experimental group patients received supportive psycho-educational interventions consisted of education, progressive muscle relaxation technique with four supportive range of motion exercises in addition to emotional support for three months. While control group patients received routine nursing care in hospital. The results were assessed for both groups by using European organization for cancer research and treatment quality of life questionnaire (EOCRT-QLQ C30) and breast cancer module.
Field experiment was conducted during the season (2011 – 2012) at Bhanine village in Tartous city. Maize seeds of Ghouta 82 variety were planted in plastic pots filled with calcareous soil .Treatments including three levels of B (0, 3, and 6 kg.ha− 1) and four levels of Zn (0, 8, 16 and 24 kg.ha−1) added to the soil, in a completely randomized block design with three replications, to study the effect of different levels of boron and zinc and their interactions on maize content of some nutrients. Results of this study showed that there was a clear effect of B and Zn and their interactions in soil on leaf content of Mn, Fe and Cu. High amounts of zinc in the soil had a clear effect on reduced leaves content of B and increased its content of K. The presence of a of B in the soil, assisted to increasing of leaf N content. There was a significant effect of B and Zn interaction on leaf content of Zn, and no effect on leaf P content.
Introduction: Ileus commonly occurs after abdominal surgery, and is associated with complications and increased length of hospital stay. Post-operative ileus (POI) is an important reason for remaining patients not permit oral (NPO) in post-operativ e period. The tradition was that when patients passed flatus, they were ready to consume a liquid diet, and then a solid food diet was gradually introduced. This approach was taken to avoid aspiration, gastric and intestinal distension, and anastomotic dehiscence. Although studies demonstrated that the conventional strict feeding regimens were not necessary, many surgeons still hesitated to allow early oral feeding. There has been concern that early oral intake would result in vomiting and severe paralytic ileus with subsequent aspiration pneumonia, wound dehiscence and anastomotic leakage. This belief has become surgical dogma, unsupported by scientific evidence. Aim: to investigates the effect of early oral postoperative carbohydrates feeding on postoperative outcome. Material and methods: forty abdominal surgery patients were randomly assigned to early oral postoperative feeding group (20) or traditional feeding group (20). In the early feeding group (study group), patients were initially started on clear fluid only 16 h after surgery and progressed to liquids (after 24 h) and then soft and regular diet in next day (after 48 h). In the post-operative period, the patients were visited each 12 h and clinical signs and symptoms such as, time of passed flatus and moved their bowels, nausea and vomiting, and the length hospital stay were assessed. Conclusions: This study showed that early oral postoperative carbohydrates feeding group passed flatus and moved their bowels much sooner than the control group thus reducing the duration of POI and hospital stay, but there is no increase in occurrence of of nausea and vomiting between tow groups.
Fifteen Shami cows available in Dier-Al-Hajar Station for improving Shami Cattle were used during 2009-2010 to evaluate the ovarian response of cows for gonadotropin releasing hormone (GnRH) or human chorionic gonadotropin (hCG) injected on day 5 of the estrus cycle during which dominant follicle is growing in the first follicular wave. Animals were divided randomly into three groups of five cows. Group 1 was left as a control and received no treatment while Groups 2 and 3 received on day 5 of the estrous cycle a single i.m. injection of 8 ?g of a GnRH agonist (Buserelin) and 3000 IU hCG, respectively. Transrectal ovarian ultrasonography was performed daily to monitor ovarian follicular dynamics and corpus luteum.
It is well established that sugar content of sugar beet increases as the plant reaches the biological maturity stage. This means that the sugar beet plant must be left in the field to complete its growth. Farmers are usually concerned with the hig hest yield of sugar beet roots regardless of their content of sugar, but sugar-processing companies are concerned mainly with the amount of sugar extracted from a certain weight of roots, in addition to the purity of the sugary juice. Farmers normally receives the price of their sugar beat crop based on the sugar content of the crop. Thus, in this type of farming, biological control is a worldwide-procedure. Biological maturity depends on ways of yield formation and a close control of the mechanisms of forming yield components (no. of roots / unit area; average root weigh; average sugar content) which require a detailed study of the characters of the grown cultivar and the overall conditions of the growing area. Results showed that harvesting of sugar beet sown in fall season befor the plant completes it’s growing cycle (in June) results in a big yield in addition to a reduction in sugar content in the roots which inturn results in a big loss in the national economy. Results indicated that delaying date of harvest up to ١٨th of July markedly increased root and sugar yield as well as sugar content in the beet roots. Increasing nitrogen rate up to ٤٠٠ kg / ha resulted in a marked increase in root and sugar yield / ha . On the other hand, sucrose content gradually decreased with excess nitrogen. Higher plant density (more than ١٠٠,٠٠٠ plants /ha) enforce for late harvesting in comparison with other densities for at least ١٠ days to obtain high yield of roots and sugar.
