Open Access Library PrePrints (OALib PrePrints) , 2014, DOI: 10.4236/oalib.preprints.1200085
Abstract: This study was conducted in gedarif research station farm for two seasons in 2013 and 2014. The objective was to determine optimum seed rate and time of harvesting mungbean for green forage and hay under rain fed conditions. The results showed different significant in three stage of cutting and three seed rate at different parameter as indicated by plant height, plant number, branch number, leave number and dry weight. The result showed highly significant between vegetative and boding stage. In the same season (2013) and (2014), also highly significant between the boding stage in seed rate tow and all stage of seed rate for the both season (2013) and (2014). The study concluded that, cutting stage can be used as indicators for plant yield and biomass as proved in the crop of the study. The study recommended that boding cutting stage can be used as practical mean to assess utilization level as expressed by growth performance indicators including dry matter and biomass from guar forage crop.
Evaluation of Corrosion Behavior of Copper in Chloride Media Using Electrochemical Impedance Spectroscopy (EIS)
Nagiub,A.M.;
Portugaliae Electrochimica Acta , 2005,
Abstract: the corrosion behavior of pure copper rotating cylinder electrode (rce) exposed to 3% nacl or artificial seawater prepared as v？t？？nen nine salt solution (vnss) has been studied using electrochemical impedance spectroscopy (eis) and polarization techniques. eis experiments for copper rce were carried out at different rotation rate from 0 rpm to 1600 rpm. polarization resistance (rp) values were obtained from both eis and polarization experiments. excellent agreement between impedance and polarization data is observed. rce experiments demonstrated that ecorr and corrosion rate for copper depend linearly on rotation speed r0.7. the results obtained showed that eis is a powerful electrochemical method to follow the change of corrosion mechanisms.
LAPAROSCOPIC ILEAL LOOP CONDUIT: AN EXPERIMENTAL STUDY IN DOGS
A.M. SHOMA
African Journal of Urology , 2002,
Abstract: Objective This experimental study in dogs aimed at establishing a technique for laparoscopic construction of an ileal loop conduit for urinary diversion. Material and Methods Eight mongrel dogs were included in the study. All of them were subjected to preoperative intravenous urography (IVU) for evaluation of the upper urinary tract. In the first four dogs (Group I) ileal loop conduits were constructed via a transperitoneal approach with implantation of the right ureter only to the newly fashioned conduit. Group II consisted of another four dogs in which the conduits were created and both ureters were reanastomosed to their walls. All procedures were done laparoscopically. Postoperatively, all dogs were evaluated using IVU and diuretic renography. The conduits were further evaluated by loopograms. Results Open conversion was not necessary in any animal. The mean operative time was 5 ± 1.5 hours and 4 ± 0.5 hours for Groups I and II, respectively. One dog of Group I died postoperatively because of urinary leakage. Thus, only three units were evaluable. Two of them showed a perfect configuration on IVU film, while a ureteroileal stricture was detected in one. Mean renographic clearance was 55 ± 10.5 ml/minute. Eight renal units could be assessed in Group II. All showed perfect postoperative configurations during radiological assessment with a mean renographic clearance of 56 ± 8 ml/minute. The loopograms showed adequately fashioned conduits in all dogs with no leakage. Conclusion This experimental study confirmed the feasibility of laparoscopic ileal conduit construction with a satisfactory outcome. Although technically challenging, ongoing technical refinements will make the performance of reconstructive laparoscopy more widely acceptable. La Dérivation Cutanée Trans-Intestinale par Voie Laparoscopique: Une Etude Expérimentale chez le Chien Objectif Cette étude expérimentale avait pour but d'établir une technique pour la confection par voie laparoscopique d'une dérivation urinaire trans-intestinale. Matériel et Méthodes Huit chiens de race Mongrel ont été inclus dans cette étude. Tous ont eu une urographie intra-veineuse (UIV) pour l'évaluation de leur haut appareil urinaire. Chez les 4 premiers chiens (Group I) la dérivation a été réalisée par voie trans-péritonéale avec implantation de l'uretère droit seul dans le conduit nouvellement confectionné. Le groupe II comprenait 4 chiens chez lesquels les conduits étaient crées et les deux uretères anastomosés dans la paroi. Toutes les opérations ont été réalisées par voie laparoscopique. En post-opératoire, tous les chiens ont été évalués par UIV et néphrographie aux diurétiques. Les conduits de dérivation ont été évalués par opacification de l'anse de dérivation. Résultats Une conversion en chirurgie ouverte n'a été nécessaire chez aucun animal. La durée moyenne de l'opération était de 5 ± 1.5 heures et 4 ± 0.5 heures pour les groupes I et II respective-ment. Un des chiens du groupe I décéda en post-
Computer simulation of modulated two-beam interference using monochromatic light
A.M. Hamed
Optica Applicata , 2004,
Abstract: Two different models are suggested to describe the fringe shift obtained from the two beam interference modulated by the phase variations of transparent objects. The first model of the fringe shift assumes a linear triangular distribution, while the second model varies as a truncated Gauss function. The Abel transform enables computation of the refractive index distribution from the theoretical data of the fringe shift. The fringe shift of the phase object is represented in the harmonic term of the intensity distribution formula. A computer program is written to plot both of the fringe shifts of the models described and the corresponding refractive indices of the phase object. Comparative results are cited in the introduction which are based on an algebraic reconstruction technique (ART) using two models; one of them has a cosine phantom field which constructs an asymmetric single peak, while the other model has cosGauss function giving an asymmetric double-peak phantom. These results are compared with our results, which gives only a single peak in both cases of linear and quadratic variations, which is convenient for use in optical fibers.
A demographic model to predict future growth of the Addo elephant population
A.M. Woodd
Koedoe : African Protected Area Conservation and Science , 1999, DOI: 10.4102/koedoe.v42i1.226
Abstract: An age-structured demographic model of the growth of the Addo elephant population was developed using parameters calculated from long-term data on the population. The model was used to provide estimates of future population growth. Expansion of the Addo Elephant National Park is currently underway, and the proposed target population size for elephant within the enlarged park is 2700. The model predicts that this population size will be reached during the year 2043, so that the Addo elephant population can continue to increase for a further 44 years before its target size within the enlarged park is attained.

Values and ethics enter the real world: a framework for public leadership and governance
A.M. Sindane
Koers : Bulletin for Christian Scholarship , 2011, DOI: 10.4102/koers.v76i4.419
Abstract: Indications are that an ethical problem exists regarding the internalisation of norms and values in the public sector. This results in an unacceptable number of public scandals related to malfeasance and it indicates that mechanisms to curb ethical violations are not always effective. All over the world governments experience such ethical violations. This article argues for a paradigm shift in public leadership and governance. What is required is a framework for the internalisation of values, ethics and norms to accentuate accountability. It is argued that answers to malfeasance do not lie in the ordinary process of education and training to conscientise public leaders about their role and compliance to policies, rules and regulations. Instead the solution is contained in the internalisation of values and ethics of public leadership and governance, and ensuring that these are upheld at all times. There should also be sanctions for unaccountability. Negotiating the reasons for not meeting set goals after the fact is a practice that compromises accountability. It is emphasised that accountability can thrive only in situations wherein values and ethics are rendered practical through public leadership and governance.

Abstract: At the present juncture of society, when reached a new level of human relationship in various fields of manufacturing, politics and newly established institutions actualized the need for further study of the phenomenon of freedom. На современном переломном этапе развития общества, когда нового уровня достигли человеческие отношения в различных сферах производства, политике и вновь институтах, чрезвычайно актуализируется потребность в дальнейшем исследовании феномена свободы. На сучасному переломному етап розвитку сусп льства, коли нового р вня досягли людськ в дношення в р зних сферах виробництва, пол тиц та новоутворених нституц ях, надзвичайно актуал зу ться потреба в подальшому досл дженн феномену свободи. Особливого значення це питання набува в умовах глобал зац . Адже саме глобальн економ чн , пол тичн , демограф чн , соц альн , нац ональн проблеми, як з новою силою проявляються на початку третього тисячол ття, змушують до переосмислення традиц йних ц нн сних понять та св тоглядно-ф лософських парадигм.
