Glucoamylase from the Isolate Aspergillus fumigatus
H.M. Cherry,Md. Towhid Hossain,M.N. Anwar
Pakistan Journal of Biological Sciences , 2004,
Abstract: Aspergillus fumigatus Fresenius was isolated from goat`s rumen and exhibited highest amylase production at temperature 37 C, medium pH 7.0 and 3 days of incubation period. Four percent starch as carbon source and 0.25% (NH4)2HPO4 as nitrogen source was found to induce amylase production by the isolate Aspergillus fumigatus. Maximum glucoamylase activity was achieved at 35 C temperature and pH 7.0 along with 4% starch as substrate concentration during enzyme-substrate reaction.

African Journal of Urology , 2003,
Abstract: Objectives : To evaluate the functional outcome of the Charleston pouch procedure as a continent catheterizable urinary reservoir using an unaltered in-situ appendix with a triangular skin flap at its umbilical stoma with few modifications to the original technique.Patients and Methods: Between February 1999 and October 2002, 34 patients (31 males and 3 females) were studied at the Urology Department, Assiut University Hospital, Assiut, Egypt. The indications for urinary diversion were radical cystectomy for invasive carcinoma of the bilharzial bladder in 27 males and three females, and incontinent epispadias in four male patients. The age of the patients ranged between 18 and 60 years (mean 48.1± 6.1 years). Mean follow up was 30 ± 4.2 months (range 11-40 months). The evaluation during the follow-up period included clinical, laboratory, imaging and urodynamic studies to evaluate the functional outcome.Results: All patients are continent (day and night). No stomal stenosis was recorded. Laboratory investigations were within normal. The upper urinary tract remained unchanged in all patients.Pouchometry revealed that the Charleston pouch is a low-pressure (4 –21 cm H2O) reservoir with a good capacity (average750 ml). Cancer recurrence was recorded in 3 patients at 12, 27 and 32 months. Conclusions: The Charleston pouch with in-situ appendix is an efficient versatile technique for the creation of a catheterizable continent cutaneous urinary reservoir. The umbilical stoma with triangular skin flap provides excellent cosmetic results. Le Réservoir de Charleston avec Appendice In Situ et Stomie Ombilicale Cachée Objectifs: Evaluer le résultat fonctionnel du réservoir de Charleston comme dérivation urinaire continente cathétérisable via un appendice insitu avec une plicature cutanée triangulaire au niveau de sa stomie ombilicale avec quelques modifications de la technique originale. Patients et Méthodes: Trente-quatre patients (31 males et 3 femmes) ont été éligés entre février 1999 et octobre 2002 au Département d'Urologie, à l'H pital Universitaire d'Assiut, Assiut, Egypte. Les indications pour dérivation urinaire étaient des cystectomies radicales pour carcinome invasif bilharzien de la vessie chez 27 hommes et trois femmes, et épispadias incontinent chez quatre hommes. L'age des patients était entre 18 et 60 ans (moyenne 48.1 ± 6.1 années). La moyenne du suivi était 30 ± 4.2 mois (11-40 mois). Le suivi était clinique, biologique, bactériologique, radiologique et urodynamique pour évaluer le résultat fonctionnel. Résultats: Tous les patients sont continents (jour et nuit). Aucune sténose stomiale n'a été notée. Les examens biologiques étaient normaux. Le haut appareil urinaire est resté inchangé chez tous les patients. L'étude des pressions du réservoir a révélé qu'elle est de basse pression (4 –21 centimètre H2O) réservoir avec une bonne capacité (moyenne 750 ml).

Abstract: ENGLISH ABSTRACT: Scheduling problems form an important class of decision-making problems where two types of decision have to be taken: allocation and sequencing. Scheduling is primarily considered with resource allocation; sequencing, however, is concerned with the order of jobs to be performed on the allocated resource (Sipper and Bulfin [8]). This paper proposes the use of a new heuristic called ABURAS, which is designed to minimize the makespan of an unrelated parallel machine scheduling problem. To evaluate the performance of the suggested heuristic, a real scheduling problem involving roof truss manufacturing at a major housing construction company is investigated. The ABURAS heuristic shows superiority in terms of reduced makespan over originally developed heuristics. AFRIKAANSE OPSOMMING: Skeduleringsvraagtukke vorm 'n belangrike versameling van besluitvormingsprobleme wat gekenmerk word deur toedeling en volgorde. Skedules hou verband met die toewysing van hulpbronne, terwyl sekwensie verband hou met volgorde. ’n Nuwe sogenaamde ABURAS-skeduleringsheuristiek word voorgehou vir praktyktoepassing. Die toepassingsprosedure word beskryf, en die heuristiek word toegepas by 'n onderneming wat dakkappe vervaardig. Die praktyktoepassing lewer bemoedigende resultate.

Abstract: ENGLISH ABSTRACT: A multi-business company is a complex entity. Evaluating corporate performance of such an organisation is even more challenging. Corporate performance is inherently multidimensional in nature, is viewed from various perspectives, and has to satisfy multiple objectives. It is multi-dimensional in the sense of being a function of many variables that drive firm performance; multi-perspectival, from various stakeholders’ standpoints; and multi-objectives are to be optimised. So there is no single corporate performance evaluation tool that can be prescribed as a stand-alone gauge; however, a unified and holistic corporate performance management system can be developed from multiple tools. This paper attempts to bring together a variety of performance management tools that have evolved and developed in theory, and have been tested and applied in practice. In developing this convergence, first a set of criteria that answers the multi-dimensional, multi-perspectival, and multi-objective requirements of a firm’s performance will be identified and weighted. Second, management tools that have been used either singly or in combination by multi-business companies are reviewed and ranked against the chosen criteria. Finally, an integrated model or framework that brings together and unifies the elements of these ranked performance management tools is proposed. AFRIKAANSE OPSOMMING: D‘n Multi-maatskappy-onderneming is ‘n komplekse entiteit. Die evaluasie van maatskappyprestasie van so ‘n onderneming is self meer van ‘n uitdaging. Maatskappyprestasie is inherent multidimensioneel, word uit verskeie perspektiewe beskou en moet veelvuldige doelwitte bevredig. Geen enkele maatstaf is beskikbaar om hierdie fasette van maatskappyprestasie te evalueer, alhoewel ‘n holistiese prestasiebestuurstelsel ontwikkel kan word gebaseer op verskillende maatstawwe. Hierdie artikel bring verskillende metodologie byeen vir die meting van maatskappyprestasie wat multi-dimensioneel, multiperspektiewelik en multi-doelwit-ge ri nteerd is. Sodoende word ‘n ge ntegreerde raamwerk vir die meting van maatskappyprestasie ontwikkel.

Abstract: The prevalence of Arcobacter butzleri and Helicobacter pylori in some foods of animal origin and the possibility of their elimination by irradiation was studied. A. butzleri was isolated from 60 % of 20 whole chicken carcasses, 16.7 % of 24 ground beef samples, 40 % of 40 bolti fish samples and 45.5 % of 44 catfish samples. Meanwhile, H. pylori was not isolated from samples. Fresh samples of chicken breasts, ground beef, bolti fish fillets and catfish fillets were radiation sterilized and inoculated with A. butzleri or H. pylori at initial levels of 107 cfu/ g. Then samplers were irradiated at doses of 0, 0.5, 1, 1.5, 2, 2.5 and 3 kGy at room temperature and the survival of these pathogens was examined post treatments and during storage at 4 ±1 °C for 7 days. Irradiation at doses up to 1.5 kGy significantly decreased the counts of these pathogens, proportionally to the applied dose. Refrigerated storage had no significant effects on the counts of A. butzleri in control samples and those survived irradiation doses up to 1.5 kGy, whereas significantly decreased the counts of H. pylori. No colony forming units were observed for these pathogens in samples irradiated at dose of 2 kGy or above. The average D10 values were 0.26 and 0.28 kGy for A. butzleri and H. pylori, respectively. Therefore, irradiation at doses approved for treatment of fresh foods of animal origin may effectively eliminate the naturally present A. butzleri and H. pylori and prevent their possible hazards.

Mott–Schottky Analysis of SnO2 Nanoparticles By impedance Measurements under Ultrahigh Pressure
Chenari H.M.
Proceedings of the International Conference Nanomaterials : Applications and Properties , 2012,
Abstract: In this study, the SnO2 nanoparticle powders were compacted into a disk shape form of under a ultra-high pressure up to 49.6 GPa. Complex impedance analysis of nano-SnO2 thick film/electrode system was studied as a function of applied potential. A calculated Mott– Schottky plot for the film is presented. Both flat-band potential and donor concentration were estimated from the space charge capacitance at a definite frequency. The film can be described as an n-type semiconductor with a high concentration of donors.
Biochemical and Hematological Studies for the Protective Effect of Oyster Mushroom (Pleurotus ostreatus) Against Glycerol-Induced Acute Renal Failure in Rats
H.M. Sirag
Journal of Biological Sciences , 2009,
Abstract: This study was undertaken to investigate the putative protective effect with antioxidant potential of the oyster mushroom (Pleurotus ostreatus) in glycerol-induced Acute Renal Failure (ARF) in rats. Four groups of rats were employed in this study, group I served as control, group II was given a single intramuscular dose of 50% glycerol in olive oil (8 mL kg-1 b.wt.), group III was given mushroom in the diet (62.5 g kg-1) and in drinking water (2.5 g L-1) for 3 weeks and group IV was given mushroom as the third group then was given a single intramuscular dose of 50% glycerol in the day 22 of mushroom administration. Oxidative stress markers in kidney, kidney abnormalities as well as hematological alteration were estimated. Glycerol treatment resulted in a marked renal oxidative stress, a significantly deranged renal function and a reduction in all hematological tested parameters. Pre-treatment with mushroom markedly reduced elevated thiobarbituric acid reacting substances, reduced glutathione, protein carbonyl and resorted the depleted renal antioxidant enzymes, attenuated renal dysfunction and the disturbances observed in hematological and biochemical parameters. These results suggest that Pleurotus ostreatus may have ability to protect the renal damage involved in acute renal failure in rats.
Ketamine as an Adjuvant to Morphine for Patient Controlled Analgesia in Morbidly Obese Patients
H.M. Kamal
Journal of Medical Sciences , 2008,
Abstract: Intravenous Patient Controlled Analgesia (PCA) with morphine is often used for postoperative analgesia in morbidly obese patients. However, the required doses may increase postoperative respiratory disorders. Adjunction of small doses of ketamine could reduce dose and related side effects. Eighty morbidly obese patients undergoing upper abdominal surgery were randomly assigned to receive (during the postoperative period) either intravenous morphine 1 mg mL-1 (morphine group: M group) or morphine with ketamine 1 mg mL-1 for each (morphine ketamine group: MK group). Morphine consumption was evaluated by cumulative doses every 8 h for 48 h together with Visual Analogue Scale (VAS) scores at rest and at mobilization. Forced Vital Capacity (FVC) and Forced Expiratory Volume in first second (FEV1) were assessed by spirometric evaluation 24 and 48 h after initiation of PCA. Incidence of adverse effects was reported. cumulative morphine consumption was significantly reduced in morphine Ketamine (MK) group. It was 84 (9) mg vs 66(6) mg 48 h after PCA (p<0.05). VAS in both groups were similar at rest and at mobilization. Compared with preoperative values, (FVC) was significantly reduced in M group than MK group: 46% (8) vs 62% (9) (p< 0.05) at 24 h and 58 (7) vs 77% (11) (p<0.05) at 48 h (FEV1) was 60% (9) vs 81% (7) (p<0.05) at 24 h and 62% (6) vs 87% (11) (p<0.05) at 48 h after PCA initiation. PaO2, respiratory rate, and SPO2 were significantly lower in M group than MK group 32 h after PCA initiation (p<0.05). Incidence of nausea and desaturation were significantly higher in M group than MK group (p<0.05). Adding small doses of ketamine to morphine for PCA decreased cumulative morphine consumption, improved postoperative respiratory function and was associated with less adverse effects in morbidly obese patients undergoing upper abdominal surgery.
