Abstract: In this investigation, two field experiments were carried out at the experimental farm of Mallawy Agricultural Research Station, Minia, Egypt, during the two successive fall and winter seasons of 2012/2013 and 2013/2014, respectively. Phaseolus vulgaris cv. Nebraska and Pisum sativum cv. Master B, Vicia faba cv. Nubaria-1 (formely Giza Blanca) were used to study the influence of three antioxidants organic acids namely, Salicylic acid (SA), Vitamin E and Acetyl salicylic acid (ASA) on some yield characters, chemical constituents and antioxidative activities of total phenolic compounds (TPCs). Five concentrations i.e., 0.1, 0.5, 1.0, 2.0 and 4.0 mM were used from each antioxidant substance. Some physical properties and approximate analysis (dry matter DM, crude protein CP; crude fiber CF, crude lipids CL and ash content AC) were studied. The results indicate that the investigated legumes are rich and good sources of CP, CF and AC. Number of dry pods per plant, 100-seed weight and dry seeds yield of the three studied crops were significantly affected by using the antioxidant treatments. The best compound that gave, in average, the highest values was acetyl salicylic acid (ASA) at 1 mM concentration, on the other hand at 0.1 and 0.5 mM concentrations the highest value was obtained by using Vitamin E.. The nitrite concentration (NO₂^-1 mg/kg) in the three legumes ranged from 4.20 to 6.5 and did not reach toxic limit level (i.e. 10 mg/kg). The highest level of nitrite was recorded in Master B and the lowest one in Nebraska. These results meaning that the consumption of these vegetable legume seeds is save. All seed samples contain less than 200 mg NO₃^-1 ion/kg and the highest concentration (155 mg/kg NO₃^1-ion) was recorded in extracts of Master B and the lowest one in Nubaria 1. Concentrations of SA in legume seed samples were higher in all treatments compared with the untreated samples (control) and the uptake of SA differs according to the given doses. Changes in SA levels causing by spraying treatment was also studied and showed sharp increases in SA contents. The concentrations of TPCs and total flavonoids (TFs) in the crude extracts of whole seeds of the studied legumes were assayed and the results indicate that seeds of Nubaria-1 (dark coat seeds) contain higher levels of TPCs (8.3 mg/g) than those determined in seeds of Nebraska (7.4 mg/g) and much higher than Master B (6.5 mg/g) whereas, TFs concentration was the highest in extracts of Nebraska.

Abstract: Background: Literature review cited that, Traumatic head injury (THI) is one of the major causes of disability, death and health related costs. The primary goal of nursing management in traumatic head injury is to maintain adequate cerebral tissue perfusion. Nursing and medical management are overlapped, with the special focus on nurses' knowledge and practices. Intensive care unit (ICU) nurses are responsible for the continuous monitoring and maintenance of physiological, psychosocial, injury prevention, and therapeutic environment values associated with THI. Thereby, this study aimed to evaluate the impact of a designed head trauma nursing management protocol on critical care nurses' knowledge and practices at Emergency University Hospital. Material and methods a quasi experimental (pre/post-test design) research design was utilized. The study was conducted on convenience sample of 50 nurses who provide direct care for traumatic head injury patients at ICUs at Emergency Hospital Mansoura University. Data were obtained using two main tools; head trauma care knowledge assessment questionnaire with the socio-demographic data sheet, and head trauma care practice observational checklists. The instructional protocol was designed based on an extensive revision of the related, recent literature. The protocol was delivered throughout ten weeks. Each week involved three sessions. Every session lasts about forty to sixty minutes. Nurses were divided into 10 groups, 5 nurses each. Results revealed that the mean knowledge and practice scores of nurses are increased immediately after implementation of the protocol with a significant statistical difference. This increased level slightly decreased following two months of protocol implementation. Also, a positive correlation was found between knowledge and practice scores of the study subjects. Therefore, the two stated research hypothesis were supported Conclusion intensive care unit nurses were lacking some knowledge and practices regarding head trauma management. The simple educational handout, demontrations and the designed protocol showed a positive impact in improving nurse’s knowledge and practices. The study recommended that establishing a written updated head trauma nursing management protocol to ensure enough knowledge and safe nursing practice. Moreover, Periodical evaluation should be conducted by the nurse educator to ensure that the standards of knowledge & practices regarding head trauma nursing management are maintained.

Abstract: The purpose of this study was to evaluate the usefulness of virtual cystoscopy using a volume rendering algorithm performed with multidetector CT in patients with different urinary bladder pathology compared with the histopathologic result. In our study about 50 examined individuals (10 females and 40 males) their ages ranging from 38 to 71 years (with 58 years mean age). These cases were classified into two main groups according to the technique; the first group subjected to virtual CT cystoscopy after air insufflation of the urinary bladder and the second group subjected to virtual CT cystoscopy after filling of the bladder by iodinated contrast material. The examination was well tolerated by all patients with no complications. All the cases underwent to conventional cystoscopy to confirm the diagnosis. In total, 58 lesions were detected with conventional cystoscopy while 53 lesions only detected on VC.

Abstract: A Study of the black scale insect Chrysomphalus aonidum L. (Hemiptera: Diaspididae) population infesting Dracena shrubs was carried out under green house conditions in two successive years (2010-2011 and 2011-2012). Results showed that this insect recorded 4 peaks during the first studied year, the highest was in 1^st of November 2010 (50.7 insects/ leaf) with maximum and minimum temperature (27.60°C, 17.35°C) and average relative humidity (79.83%). While in the second year it recorded 3 peaks of population; the highest peak was in mid of June (112.5 insects / leaf) with maximum and minimum temperature (32.20°C, 21.35 °C) and average RH %. (71.70%). In both years there were three generations. A very slight population was recorded for the associated endoparasitoid Habrolepis diaspidi (Rrisbec) (Hymenoptera : Encyrtidae). Results also, indicated that, the maximum, minimum temperature and relative humidity had negative significant exponential relationship regression on different alive stages.
