Abstract: Background: Febrile convulsions is a common disorder in childhood. There are different hypotheses about neurotransmitters and trace element changes in biological fluids which can have a role in pathogenesis of febrile convulsions. Objectives: We aimed to investigate level of zinc, copper and iron profile parameters in 40 children with simple febrile convulsions aged between 6 months and 3 years and compare them with 40 age-matched controls with febrile illness without seizures in Banha city in Egypt. Methods: After informed consent, detailed history was taken and clinical examination was performed for both cases and controls, blood lab to measure serum ferritin by ELISA, iron, zinc and copper levels by Colometric method were performed for all studied children. Results: The median serum ferritin levels in cases and controls were 10 and 46.5 µg/dl, respectively, the difference was statistically highly significant (P = 0.00) and the median serum zinc levels in cases and controls were 53 and 95 µg/dl, this difference was statistically highly significant (P = 0.00). Also the median serum copper level in cases and controls were 120 and 93 µg/dl, the difference was statistically not significant (P >0.05). We found positive correlations between occurance of febrile convulsions and positive family history of febrile convulsions, malnutrition. Low serum levels of hemoglobin, iron, ferritin and zinc. Conclusion: Serum ferritin and zinc deficiency are risk factors for simple febrile convulsions while serum copper show no significant changes in cases of febrile convulsions. Recommendation: Providing adequate iron and zinc supplementation in early childhood may lead to significant decreases in febrile convulsions incidence in young children.

Abstract: In the present study the Egyptian Barki wool fibers were graded into five groups: coarse fibers with high bulk (G1), coarse fibers with low bulk (G2), fine fibers with high bulk (G3), fine fibers with low bulk (G4) and (G5) non-graded fibers (control). Results in the present paper indicate that G3 had the highest bursting strength among all groups, while G2was the lowest one. Previous result could be explained by the ability of fine fibers to stretch rather than being break because of crimps in addition to the springy behavior which makes these fibers more able to stretch under tension rather than cut. For that, bursting strength had a highly significant and positive correlation with bulk (r = 0.53), resilience (r = 0.67), crimp (r = 0.69) and staple strength (r = 0.77). Bursting strength had a negative with highly significant correlation with fiber diameter (r = - 0.69) and medullated fiber percentage (r = - 0.69). Also bursting strength had a negative and highly significant correlation with all irregularity measurements (r = - 0.68 with thin places, r = - 0.95 with thick places and r = - 0.60 with neps). Bursting strength also increased with increasing whiteness (r = 0.43), while decreased with increasing yellowness (r = -0.62). A highly significant positive correlation found between bursting and Tog (r = 0.83).

Abstract: This paper investigates a new control strategy of a wind energy driven by a variable speed wind turbine self-excited induction generator (SEIG) connected to a public network. Also, the steady state analysis of the SEIG is introduces taking the saturation effects into consideration. The proposed system consists of a three-phase induction generator feeds its stator electrical output power into an infinite bus-bar via a static power conditioner. The power conditioner used here consists of a diode bridge rectifier and an inverter bridge thyristor tied together through a d.c. link reactor of high inductance. The SEIG in this work driven by a variable speed wind turbine is proposed with a fixed pitch angle to reduce the  system cost and easy to run.At higher generator speeds, the generated voltage as well as the stator current exceeds its rated values resulting in generator thermal overheating. At low wind speeds the SEIG operates at constant generated voltage, increasing the wind speed increases the generated power which results increasing of the stator current.  In order to protect the generator against this thermal overheating, the generator should be controlled via the power conditioner to maintain rated stator current. So, it becomes necessary to add two loops in order to automatically control and protect the generator. The first loop operates in the speed range under the rated stator current to keep the generator voltage constant at rated value. As soon as the stator current attains its rated value, the second control loop automatically controls the system to run at constant rated stator current to obtain optimum generator utilization without overheating. The obtained theoretical and experimental steady state characteristics demonstrate effectiveness of the proposed strategy.

Abstract: The influence of physical factors on spatial soil erosion risk was assessed for Wadi Kufranja watershed (126.3km2), north Jordan highlands. Such research is significant for monitoring future land use/cover changes, including agricultural expansion and deterioration of forest resources. The spatial relationships between soil erosion risk / intensity map and the environmental factors affecting soil erosion were investigated. The results indicate that soil erosion is highly correlated to specific terrain units, slope categories, elevation zones, land use/cover type, and aspect over the catchment. 67.7% of minimal to low soil loss area occurred on slope categories 0-6º and 6-15º, and 23.5% of moderate to severe soil erosion occurred on terrain characterized with the same slope categories, while, 6.45% of areas are exposed to severe soil loss, and this occurred on 15-25º slope category. 33.22% of soil erosion was distributed on southern slopes, while 62.8% of soil erosion occurred in areas of elevation ranging between 500 and 1100 m a.s.l. 46.87% of soil erosion was found in mixed agricultural land, 22.3 in forest areas, and 17.31% in open rangeland and bare soils. By contrast, five terrain units display an area of 55.06% of soil erosion, while, the alluvial fan areas exhibit the lowest soil erosion loss. The reported results provided viable information essential to control soil erosion, reduce soil loss, and achieve sustainable agricultural development.

Abstract A simple method has been developed for the preconcentration of mercury based on the adsorption of its ammonium pyrrolidine dithiocarbamate (APDTC) complex on amberlite IR-120 column. The influence of complexing agent, pH, amount of resin, eluting agents and flow rate has been investigated in detail. The effects of matrix ions on the retentions of the analyte were also examined .The adsorbed complex could be eluted using 1M HNO3/ acetone and the concentration of mercury was determined by cold vapour atomic absorption spectrometry (CVAAS).The recoveries of the analyte were generally more than 95% with a low RSD. The proposed method has been successfully applied for the metal content evaluation in samples including water, wastewater, cow milk, dry milk, rice, fish and canned tuna.

Abstract: The use of electricity brings with it an electric shock hazard for humans and animals, particularly in the case of defective electrical apparatus. In electricity supply systems, it is therefore a common practice to connect the system to ground at suitable points. Thus in the event of a fault, sufficient current will flow through and operate the protective system, which rapidly isolates the faulty circuit. Therefore, the connection to ground is required to be of sufficient low resistance. Because the topography of Jeddah city includes coastal, sandy, and rocky areas, the soil resistivity will differ across city locations, thus affecting the efficiency of the grounding circuit. To design an efficient grounding circuit, we conducted experiments to measure the soil resistivity for each soil type at different locations, taking into account factors such as salt, moisture, and density. The results of these experiments are preliminary measures for designing grounding grid systems for different topographical areas.

Abstract: Backgrounds: Ovarian torsion accounts for approximately 3% of cases of acute abdominal pain in pediatric population. The treatment of ovarian torsion is often delayed because of diagnostic uncertainty and dependence on radiologic confirmation. More urgent intervention for ovarian torsion should be considered in girls with lower abdominal pain. The purpose of this study is to present our experience with laparoscopic management for ovarian torsion in children and adolescent with a focus on the procedures of adnexal conservation surgery. Patients and methods: This is a retrospective study of 39 consecutive girls with ovarian torsion underwent laparoscopic management in the period from April 2010 to September 2012. Records of patients that have been subjected to laparoscopy for ovarian torsion were reviewed and evaluated. All patients were subjected to laparoscopic management of ovarian torsion. The main outcome measurements of this study included; feasibility, accuracy of laparoscopic management of ovarian torsion, operative time and intra and post-operative complications.  Results: In this study 39 children with ovarian torsion were operated upon laparoscopically. Their mean age was 6.54± 1.82 years (range = 4 – 14 years). All procedures were completed laparoscopically without any conversion. In 32 (82.05%) cases the ovary can be saved with de-torsion and fixation, while in 7 (17.95%) cases, the ovary was gangrenous and removed. Associated ovarian cyst was present in 4 cases of ovarian torsion Mean operating time was 36±2.3 minutes for unilateral and 45±1.7 minutes for bilateral twisted ovary. All patients achieved full recovery without intra or postoperative complications and were discharged on the same day of admission.  Conclusion: Laparoscopic management of children and adolescents presenting with adnexal torsion is feasible, safe and accurate method. It is a good alternative option to open methods in the management of adnexal lesions. Laparoscopic treatment of adnexal torsion in children and adolescent is as an emergency procedure and should be more conservative as possible to preserve the subsequent fertility.

Abstract: Microbial proteases represent one of the commonly used industrial enzymes. Ps. aeruginosa PAO1 was used in the present study for the production of protease. Maximum protease production was observed in 10 g/l tryptone basal medium with 5 g/l glucose at pH 7.0 when inoculated with 4% of 24h broth culture and incubated at 37 ºC for 48h with agitation speed of 150 rpm. Removal of Na+ or K+ or Mg++ or Ca++ or PO4--- from fermentation medium has an inhibitory effect on protease production. The enzyme was characterized biochemically; it has maximum activity at pH 8 and 40-50ºC in crude extract after 60 minutes of incubation. The enzyme was stable in the presence of K+ or Ca++, Na+ and Ba++ slightly enhanced its proteolytic activity whereas Mg++ and EDTA reduced the activity of protease. The activity of protease enzyme increased in B-mercaptoethanol (BME) and Triton X-100 in all concentrations tested. The protease enzymatic activity was measured in the presence of detergents, Cortex®, Arial®, Persil® and Elnabolsi® retained residual activity more than 60% after 60 min incubation while in Feba® 10% of its activity was retained. Also, the enzyme is stable in the presence of 1g/l SDS, which is the common ingredient in modern bleach-based detergent formulations, while its activity decreased with increasing the concentration of SDS. Based on these findings Ps. aeruginosa PAO1 protease shows a good potential for application in detergents.

Abstract: Greenhouse and field experiments were carried out at Giza research station to evaluate ten alfalfa genotypes against three fungi causing seedling damping-off disease (Fusarium oxysporum, Macrophomina phaseolina and Rhizoctonia solani). Examined genotypes included two exotic varieties (Cuf-101 and Salt America), seven local populations (Balady, Fixed-N, New valley-1, New valley-2, Siwa, Esmaelia-1 and Esmaelia-94) and New salt population (Sinai 1). R. solani was the most causal pathogen reducing significantly fresh and dry shoot yield followed by M. phaseolina and F. oxysporum, respectively. The local populations Siwa and Ismaelia-1 expressed the best performance for yield superiority and agronomical traits in comparison with the exotic populations. New Salt pop., Salt America and Siwa populations ranked as the highly resistant against seedlings damping-off disease. Selection between and within alfalfa populations for high yielding ability and resistance degree to seedling damping-off disease produce a promising population can be used in the future breeding program. SDS-protein banding patterns of the ten alfalfa populations grown under normal (non-stressed) and fungal stress conditions were found to be useful in developing biochemical markers associated with resistance to damping-off pathogens. The obtained results revealed unique fingerprint characterized for each studied population under non-stress conditions. Similarity indices and consensus tree were developed on the basis of the protein banding patterns of the ten alfalfa populations using protein banding patterns under non-stress conditions. Consensus tree was developed on the basis of the bulked protein banding patterns of the ten alfalfa populations grown in infested soil with the three tested fungi caused seedling damping-off disease. The Dendrogram was gathered the resistant populations in one main cluster and almost all highly susceptible populations together in the same group.

Abstract: Background: Descending necrotizing mediastinitis is the most lethal form of mediastinitis. It occurs as a complication of oropharyngeal or cervicofascial infections that spread along deep cervical fascial planes into the mediastinum causing widespread cellulitis, necrosis, abscess formation and sepsis. OBJECTIVE: The purpose of our study was to determine the clinical usefulness of percutaneous catheter drainage compared with surgical drainage for descending necrotizing mediastinitis. Patients and Methods: Thirty-nine patients with clinically and radiographically diagnosed DNM were included. Retrospective chart review was performed. The mean age was 28.5+ 2.6 years. DNM occurred as a complication of peritonsillar abscess in eleven patients, retropharyngeal abscess in fifteen patients and dental abscess in thirteen patients. Immediately after the diagnosis of DNM, broad-spectrum antibiotics were administered empirically for all patients. Trans-cervical drainage was performed in all cases. Residual mediastinal collection was found in twenty eight patients. Fifteen of them were successfully drained percutaneously (C group), while right thoracotomy was necessary for the remaining thirteen patients (S group). Results: No statistically significant difference was found between the two groups in sex (male to female ratio), age, time from the appearance of symptoms to diagnosis, duration of mediastinal drainage, duration of antibiotic therapy, mortality or complications. ICU stay was significantly longer for S-group patients than C-group patients. Also S-group patients were in need for analgesics and blood transfusion more than C-group patients Conclusions: Cervical approach may be enough for mediastinal drainage. PCD is the option of choice for cases with residual post-operative mediastinal abscesses and thoracotomy should be kept for cases that cannot be treated by PCD.

Abstract: Background: Asthma is a major public health problem worldwide with wide differences in prevalence and severity throughout the world. Asthma is by far the most common of all chronic diseases of childhood. Objectives: to determine the prevalence of bronchial asthma and to investigate its impact on the cognitive functions and academic achievement among preparatory school children in Damietta Governorate. Methods: This work was done in two steps: (1) Determination of the prevalence of asthma for this purpose, a cross-sectional study was conducted during the academic year 2012-2013. Total number of students included in the study was 1426 (758 from urban and 668 from rural regions) with mean age 14.3±0.7 years. The questionnaire was filled by the participants themselves. (2) Assessment of impact of asthma on the cognitive function and academic achievement, for this purpose, Case control study was used to compare the asthmatic cases with control group. Results: The prevalence of asthma was 9.1%. The asthma was more prevalent among males (11.5%), than females (7.1%). There was no statistically significant difference between asthma and residence, parent's education and parent's occupation (P ˃ 0.05 ). The asthma was more prevalent among students living in the lowest economic levels and those with high crowding index. The consanguinity among parents (OR=2.44; 95% CI: 1.62–3.66), positive family history of asthma (OR=3.79; 95% CI: 2.55–5.64), passive smoking (OR=2.74; 95% CI: 1.84–4.07), presence of other allergies (OR=2.37; 95% CI: 1.62–3.48), contact with birds (OR = 1.96; 95% CI: 1.34–2.87), contact with animals (OR=1.49; 95% CI: 1.02–2.17), presence of cockroaches (OR=1.73; 95% CI: 1.17–2.57), and frequent chest infection early in life (OR=2.05; 95% CI: 1.39–3.02) were risk factors which were significantly associated with asthma. There was a significant diminution of IQ total scale and classification scores among asthmatics. The mean free recall scores for asthmatics was (8.91 ± 3.74), compared to (11.54± 2.73) for control. There was statistically significant difference between asthmatics and controls regarding midyear Mathematic and Arabic scores (P < 0.05 ). Conclusion: The bronchial asthma is a significant health problem among school children in Egypt, and the following are recommended: Further in-depth study are in need to be conducted to explore the social, psychological and economic impacts of bronchial asthma on children, and to highlight the best prevention and control strategies for asthma in Egypt. Intensifying health education campaign to raise public awareness about the risk factors of asthma and its impact on school performance among school children. Establishment of a hotline to deal with public inquiries and all questions about asthma.

Abstract: Concrete structures are still suffering from different types of distress such as cracking and deformation. At present, the characterization of the concrete structures is implemented using two different concepts. The first concept is based on performing laboratory-testing methods on prepared concrete specimens. In fact this concept should be taken with great care and cautious. The second concept is based on conducting large scale testing programs implemented directly on the structures. The main disadvantages of this concept are related to its failure to measure the specified characteristics directly and they need back calculation to predict the required properties. Secondly, they are large and expensive equipment. However, both concepts are not beneficial in predicting or describing the mode of failure because they are macro-structural analysis based evaluation. Recently attempts were made to use the Digital Image Analysis technique DIA to evaluate the aggregate gradation of concrete mixes. It is believed that the application of the DIA technique should be extended to evaluate the microstructure characteristics. The experimental program and DIA were carried out on 96 specimens. The compression and tension test were carried out on 72 concrete cylinders made with three different mixes which contained gravel or dolomite as coarse aggregate, and compacted either manually or mechanically. The DIA was implemented on 6 vertical sections and 18 horizontal sections. The results showed that the DIA is an effective technique to evaluate the performance, quality and uniformity of concrete mixes. The results of the compression and tension were in a good agreement with the results of the DIA.

Abstract: This paper tried to test independence or dependence of sustainable development by evaluating the relationship or lack of significant relationship between the considered independent variables. Another objective of this paper is to determine and rank barriers to sustainable development. In both cases, this paper finds its target. Kolmogorov Smirnov test showed that according to the amount of significance of variables, the assumption for sample normal distribution is not rejected. Pearson correlation coefficient test showed that the absolute value of correlation coefficient of subsidiary hypotheses are respectively 0.158695, 0.088511, 0.126509, 0.097899, 0.127403, 0.03755, 0.173447, 0.105498, 0.084488, and the Sig statistic for all variables equals to or is smaller than 0.003. These calculations indicate that there is a significant direct relationship between defined independent variables in this study and meta-cognitive strategies and the Sig statistics for all variables in the studied statistical population equals to or is smaller than 0.003. Analysis and study of the computational results of the new and advanced methods of partial least squares for structural equation (VPLS) showed that the t-student estimated for each of the model coefficients was more than 95% and it can be concluded that the research hypotheses with calculated coefficients are confirmed. Also the coefficient of determination was calculated as (R = 0.892), which indicates that approximately 89%, variations of the dependent variable (sustainable development) are explained and described with objectives of progress and efficacy in this study. This paper also showed that per one unit increase in the barriers, how much sustainable development reduces.

Abstract: The aim of this study was to determine the prevalence of Listeria monocytogenes in food outlets in Saudi Arabia and study its cross-contamination of surfaces and antibiotic susceptibilities. Overall, 933 samples were surveyed, comprising 96 cutting boards, 90 conveyer belts, 216 handheld baskets and 531 plastic bags. The analysis revealed that 98/933 (10.5%) and 47/933 (5.9%) samples were positive for Listeria spp. and L. monocytogenes, respectively. In addition, the prevalence of L. monocytogenes was the highest on cutting boards, followed by handheld shoppers’ baskets and conveyer belts. The results indicated that L. monocytogenes cross-contamination of items not known to be primary sources of L. monocytogenes, such as plastic bags, is commonplace during the purchasing process. Plastic bags from leaving shoppers were found contaminated with the offensive pathogen at a rate of 2.5%, 6% and 7% in small grocery shops, supermarkets and butcheries, respectively. Handheld baskets were contaminated with L. monocytogenes at a rate of 3.6% and 7.5% in small grocery shops and supermarkets, respectively. Handheld baskets were contaminated with L. monocytogenes at a rate of 3.6% and 7.5% in small grocery shops and supermarkets, respectively. The survival rate of L. monocytogenes on studied fomites was also experimentally determined for all tested surfaces and found to be the highest on cutting boards. These findings confirm the need to regularly disinfect cutting boards, conveyer belts and handheld baskets. The most contaminated surfaces, cutting boards in particular, may require regular disinfection protocols. In addition, shoppers must be made aware that their plastic bags could be contaminated with L. monocytogenes. Antibiotic susceptibility testing, performed on 108 L. monocytogenes isolates, indicated that resistance was common against augmentin, erythromycin and cloxacillin and that amoxicillin, gentamicin and chloramphenicol were the most effective antibiotics.

Abstract: Infertility has been known to cause serious social and emotional problems worldwide, especially in developing countries like Egypt and there is no certainty as to the probable cause hence this research work. In this study a total of 100 samples, comprising 50 Seminal fluidand 50 testicular biopsy samples were collected from one hundred infertile men patients, attending the fertility clinic at the International Islamic Center for Population Studies and Research (IICPSR), Al-Azhar University, Cairo, Egypt. A variety of six pathogenic bacterial species; Enterobacter cloacae Es-1, Escherichia coli Es-2, Staphylococcus haemolyticus Es-3, Staphylococcus aureus Es-4, Bacillus cereus Es-5 and Kocuriarhizophila Es-6 were isolated. The obtained bacterial species were subjected for antibacterial activity of different actinomycete cultures isolated from different localities at Egypt, it was found that an actinomycete culture Al-AK-6 isolated from a water sample collected from Abo Keer city, Alexandria governorate, Egyptwas found to be the most active against the isolated bacterial pathogens. Identification of this isolate was performed according to spore morphology and cell wall chemo-type, which suggested that this strain is a streptomycete. Further cultural, physiological characteristics and phylogenetic analysis of 16S rRNA gene indicated that this strain is identical to Streptomyces minutiscleroticus(accession number JX905302.1) and then designated Streptomycesminutiscleroticus, strain Al-AK-6. In its culture supernatant, this organism could produce one major bioactive compound belonging to macrolide antibiotics groupexhibited strong antibacterial activity against the isolated testis-pathogens.

Abstract: The present study deals with the infestation of Lithognathus mormyrus by Nerocila bivittata from Abu Qir Bay, Alexandria, Egypt. The market-sized of hosted fish were infested in approximately 10.26% of N. bivittata during summer season. The lateral side of the fish towards the end of trunk and begging of tail was the site most intensively infested by this parasite. At the site of attachment, the skin host was recognized by batches of clear brownish in colour with have external abnormalities such as skin ulcers, scale less and discoloration. The cymothoid isopod, N. bivittata damaged the epidermis, dermis and muscular tissue of L. mormyrus at the area of attachment by dactyls. These dactyls of the pereopods penetrated into the skin and anchored the isopod to the fish host. The parasite tore the epidermis layer of the fish host using their mouth parts and fed on the blood stream beneath. The infested fish were similar in length and lighter in weight and fecundity compared to the uninfested fish. The correlation coefficient “r” in relation between standard length and fecundity was significant for uninfested and infested fish.

Abstract: In this study we assessed the diagnostic performance of chest ultrasonography in pulmonary edema. Differential diagnosis between acute cardiogenic pulmonary edema (APE) and acute lung injury/acute respiratory distress syndrome (ALI/ARDS) may often be difficult. We evaluated the ability of chest sonography in the identification of characteristic pleuropulmonary signs useful in the diagnosis of ALI/ARDS and APE. Material and methods:97 patients with provisional diagnosis of pulmonary edema were included in this study,portable CXR, bedside U/S and CT chest were done to all cases.we used CT chest findings as a gold standard for diagnosing pulmonary edema and detecting its type(etiology). Results: US in CPE: sensitivity was 93.4%, specificity: 93.3%, PPV: 98.6%, NPV: 73.7%, accuracy:87.6%. US in NCPE: sensitivity was 86.7%, specificity: 93.4%%, PPV: 72.2%, NPV: 97.5%, accuracy: 86.6%. CXR in CPE: sensitivity was 41.6%,s pecificity: 90.0%, PPV: 97.0%, NPV: 16.7%, accuracy: 42.3%. CXR in NCPE: was 60.0%, specificity: 90.0%, PPV 46.2%, NPV: 94.6%, accuracy: 78.4%. Conclusion: chest U/S is a valuable tool for diagnosis of pulmonary edema and in detecting its etiology,portable CXR is poorly sensitive tool in diagnosis of pulmonary edema and in detection of its etiology.
