Authors: أ.د. محمد سمير ماضي  , بسام ناجي أحمد  
Published: January 2024

يستخلصُ الباحثُ من خلال بحثه الموسوم بـ"ترجيحات الإمام العليمي في تفسيره "فتح الرحمن في تفسير القرآن" إلى أنَّ الترجيح لحُكمٍ أو رأيٍ أو قراءةٍ قرآنيَّةٍ يكونُ بالاعتماد على النصّ القرآنيّ نفسه أو القراءة القرآنيَّة التي يراها مُرجّحةً لرأيِه، أو بالاعتماد على الحديث النبويّ الذي يُفصِّلُ ما أجمله القرآن أو يشرحُ ما غَمُضَ معناهُ، كذلك بالاعتماد على ما يُسمَّى بالناسخ ليكونَ هو المُرجّح، أو بالاعتماد على اللغةِ العربيَّة من خلال معاني الألفاظ والعبارات والبلاغةِ فيها، لتكونَ مُرجّحةً لذاك الحُكم، وكذلك لا ننسى ظاهرَ النصّ أو حقيقةَ الألفاظ التي نأخذُها أوّلًا، فإن تعذّرت نأخذ المجاز، مع الكثير من المُعتمَدَات التي أخذ بها المُفسِّرون في ترجيحاتهم، ثمَّ اعتمدها الشيخ العُليمي -رحمه الله-، سيَّما وأنَّهُ حنبليُّ المذهب، غيرُ متعصبٍ له غالبًا.
وخُلاصةُ القولِ أنَّ المرجِّحات للرأي الذي يراهُ العليمي كثيرة، كان أهمّها القرآن بالقرآن نفسه، ثُمَّ القراءات المتواترة، ثُمَّ السنَّة النبويَّة، ثُمَّ غيرها ممَّا نبشْنا أمثلتها في القرآن الكريم.

Myeloprotective and Hematinic Influence of Harungana madagascariensis in Benzene-initiated Onco-hematologic Process in Wistar Rats
Authors: Ola Olaniyi Solomon , Nwamaka Clement-Iroh Favour , Fagbohun Funmilayo Deborah 
Published: January 2024

Background: Harungana madagascariensis is a medicinal plant that is traditionally utilized for the treatment of anaemia. Benzene constitutes an occupational toxicant due to its adverse effect on hematology of exposed industrial workers leading to onco-hematology. Therefore, the efficacy of Harungana madagascariensis against benzene-induced pre-leukaemic condition was investigated in rat model.
Methodology: Hematological disturbance leading to pre-leukemic conditions was induced in Wistar rats by intraperitoneal administration of 400mg/kg of benzene in propan-2-ol:water (1:1 v/v) every other day for 28 days. Following benzene intoxication, 200 mg/ kg HM was administered orally for 14 days. Hematological parameters and blood cell morphology were compared between baseline control and benzene-intoxicated rats with or without HM extract treatment.
Results: BZ-induced hematologically disturbed rats exhibited anaemic symptoms marked by reduction in hemoglobin level, red blood cells, and packed cell volume with morphologic blast cell appearance, polychromasia, hypersegmented neutrophil, anisocytosis and poikilocytosis. Moreover, there was an altered redox status depicted by a significant reduction in plasma level of total sulfhydryl content with concomitant increase in advanced oxidation protein products (AOPPs) that were accompanied by increased frequency of micronucleated polychromatic erythrocytes and hypercellularity in the bone marrow of benzene intoxicated rats. However, treatment with Harungana madagascariensis restored blood hematology and alleviated the blood cell morphological alteration induced by benzene. It also improved plasma redox status, reduced the frequency of micronucleus and improve the architecture of bone marrow cellularity in treated intoxicated rats.
Conclusion: Harungana madagascariensis protected against benzene-induced hematological alterations leading to pre-leukemic conditions in Wistar rats.
Recognition and Prevention of Hospitalised Malnutrition: A Case Report
Authors: Elfagi Salima , Nouh Faiza , Boshofa Esra 
Published: January 2024

Rationale: Poly-trauma post road traffic accident often induces a state of malnutrition due to the pathological changes and the insufficient protein and caloric intake for long time. If left unmanaged, malnutrition will have negative consequences on rehabilitation. Nutritional intervention provides caloric requirements and the nutritional support necessary to cover the daily nutritional needs and help contrast hospitalised infections. Our hypothesis is that integration of organised and continuous nutritional assessment and management can enhance prevent the state of malnutrition and increase rehabilitation outcomes.
Patient Concerns: We present the case of an adult man with Poly-trauma post caused by road traffic. The patient underwent tracheostomy and percutaneous endoscopic gastrostomy (PEG) procedures, had severe consciousness disorder.
Diagnosis: He has severe consciousness disorder that necessitated the tracheostomy and the PEG.
Interventions: Our approach included regular nutritional assessment and caloric calculation and implementation of as well as the gradual introduction of diet from NPO to clear liquid, as well as using of supplements and enteral formulas.
Outcomes: The patient was followed for seven months during which the metabolic/nutritional pattern and the blood tests improved, normal weight restored, and consciousness regained.
Conclusion: Nutritional intervention integrated has prevented drastic loss in weight, a better recovery, and the stabilization of the metabolic-nutritional framework. Nutritional approach used has contributed to the reduction of recovery times, making the therapeutic path more effective and applicable.
A Current Update on Neospora caninum
Authors: Fayisa Wakgari Oljira 
Published: January 2024

Neospora caninum is an apicomplexan protozoan parasite, which was first identified as a cause of canine paralysis. This parasite is now recognized as an important cause of reproductive problems and abortion in cows. Prior to its first recognition in Norwegian dogs in 1984 and consequential classification as a distinct species in 1988, many N. caninum infections were misdiagnosed as toxoplasmosis. Neospora has a complex life cycle and transmission routes. Carnivores probably become infected by ingesting tissue cysts containing bradyzoites, and herbivores probably become infected by the ingestion of food or drinking water contaminated by N. caninum sporulated oocysts from the feces of carnivores. During pregnancy it becomes activated again, breaks out of the tissue cysts and migrates to the placenta. Infection of the placenta may lead to abortion, which would provide a source of contaminated meat for definitive hosts. In addition, the parasite may be transmitted to the foetus, which can lead to the birth of congenitally and persistently infected calves. Most reports of neosporosis outbreaks have occurred in cows that are intensively managed; thus, the incidence increases as larger cattle farms with intensive feeding practices become more common. Immunofluorescent antibody test (IFAT) and indirect enzyme-linked immunosorbent assay (ELISA) and histopathology of fetus are used for diagnosis. At present, there is no effective treatment for bovine neosporosis. Control of abortion in infected cattle depends on saving food and water sources and the grazing environment from feces of carnivores, properly discarding aborted feoutus and control of dog.
High speed puncture impact studies of three low pressure styrene thermoplastic structural foam plaques
Authors: Progelhof R. C. , Kumar S. , Throne J. L. 
Published: April 2003

AbstractThe constant velocity puncture impact characteristics of three polystyrene low pressure thermoplastic structural foam plaques manufactured at identical processing conditions were measured. The test results showed that the impact performance varied, significantly over the plaque but with less variation between plaques. However, the variation does illustrate the difficulty in predicting impact performance of TSF parts. The specimens failed in a brittle manner though some did exhibit ductile compression under the impactor before the plaque failed in a brittle manner. The energy to fracture was satisfactorily correlated with a power law relationship.

Details of some very useful research with polypropylene are discussed.
“Structural web molding” a new development in low pressure smooth surface technology
Authors: Anderson Dave , Hunerberg Ed 
Published: April 2003

AbstractStructural web molding has much to offer our industry by augmenting the structural foam process while at the same time creating new applications for structural plastic products. With future trends towards dwindling resources and ever increasing energy and labor costs, this new technology has the ability to meet these challenges head on; by reducing finishing costs, molding lighter weight parts without sacrificing performance and increasing productivity with shorter cycle times.Product development programs are just beginning, with specific goals for determining detailed knowledge of process conditions and cost data. In the near future, we hope to report on the first commercial application of the structural web process.
Single‐Screw devolatilizer for polymer melts
Authors: Scharer Hans R. , Rizzi Marc A. , Hold Peter 
Published: April 2003

AbstractChanges in air quality standards and new polymer manufacturing technologies have renewed interest in polymer melt devolatilizing. Unfortunately, little data is available to aid in the design and scale up of melt devolatilizing single‐screw extruders.As part of the ongoing development activities of Farrel Company, melt devolatilizing in various devices has been under study for a number of years. In order to be able to develop analytical methods of predicting performance and scaling up from small scale test stands, some elementary devolatilizing studies were carried out. Theoretical predictions based on classical diffusion theory were compared with actual results, leading to a revised model of the actual melt devolatilizing process. Based on this revised model, several novel single screw devolatilizing concepts were proposed, built and tested. In this paper, we are presenting some of the theoretical work underlying these studies as well as test results on conventional single‐screw devolatilizing sections. We hope to be in a position to divulge additional information on some of the novel devolatilizing devices at the time of the presentation of the paper.
Using ram velocity to control IMM part quality
Authors: Aloise A. C. , Notte A. J. , Rizzi M. A. 
Published: April 2003

AbstractOne of the primary factors to consider during an injection molding cycle is the judicious switch‐over from HIGH to HOLD injection pressure setting. Historically, this switchover was effected either as a function of time or ram position. Unfortunately, neither of those parameters correlated satisfactorily to the processing event that was supposed to be detected, i.e., the “packing” of molten polymer in the mold. There are several IMM Process Controllers that directly sense rate of change of cavity pressure, but these require special transducers to be inserted in the mold. This paper describes a scheme that uses the feedback of injection ram velocity to determine mold packing and the resulting optimum point at which pressure switchover should be initiated.
