Abstract

The extensive use of pesticides on crops and overfishing illegally by fisherman in recent years in the south of Iraq, causing serious problems on non-target organisms leading to a number of pathological and disturbed biochemical alterations. Effect of chlorpyriphos pesticides on glycogen, lipid and protein contents of the viscera, mantle and foot at the end of 48 h and 96h of LC50 of the sub-lethal concentration (0.01, 0.06 ) mg / l, on the freshwater snail Bellamya bengalensis was studied. Significant differences were noticed at the different tissues contents to the both concentrations at 24h and 96h.

Abstract

The present study investigated the color alteration of heat-polymerized acrylic resin specimens exposed to 7 staining solutions (black tea, green tea, coffee, Pepsi, tomato paste, cigarette and diet Pepsi) for two weeks and compared with that exposed to distilled water. Five specimens were used for each group. The specimens were of rectangular shape measuring 5mm width, 40mmlength and 2mm thickness. After the two weeks the light transmission percent values for each specimen were determined by a spectrophotometric device. The result of this study revealed that the distilled water specimen group had the highest mean value of light transmission followed by diet Pepsi and Pepsi groups, coffee group had the lowest one. Further, coffee had a staining effect on resin specimens more than tea, cigarette and tomato paste group. In addition this study showed that resin specimens discolored by black tea more than green tea.

Abstract

Many Architectural studies deals with concept of adaptation in architecture with different ways various according to the trend of each study, this show’s the importance of studying the concept of adaptation in the architectural field in general. This research tray to focus on the concept of the adaptation of type in architecture because it’s important in the generation of the new architectural models and the reiteration of the typological chain. Reviewing previous studies focusing on this concept show’s the absent of a theoretical frame witch separate a specific items of the process of adaptation of the architectural types through different natural and cultural effects. Thus, the problem her was the absence of a specific imagination of the procedures and mechanisms for achieving adaptation of the architectural types through different natural and cultural effects. To solve this problem, the researcher adopted the approach of building a theoretical framework for the adaptation of type in architecture, Witch includes the items: The target of adaptation, the kind of effect which cues adaptation, the procedures and mechanisms to achieve adaptation. The achievement of these items depended on the help of the previous studies.Key words: Adaptation, type, Typological Transformation, alteration

تناولت العديد من الدراسات المعمارية مفهوم التكيف Adaptation)) في العمارة بصيغ تنوعت بحسب التوجه البحثي لكل دراسة، الأمر الذي أكد أهمية المفهوم ضمن المجال المعماري بشكل عام، وقد أختص هذا البحث بالتركيز على دراسة التوجه البحثي المتعلق بتكيف النمط في العمارة لأهميته في ولادة النماذج المعمارية الجديدة وتكرار السلسلة النمطية، ولكن الدراسات التي ركزت على هذا التوجه البحثي لم تتوصل إلى بلورة إطار نظري يعزل مفردات واضحة ومحددة لعملية تكيف الأنماط المعمارية بتغير المؤثرات الطبيعية والحضارية، في ضوء ذلك تمثلت المشكلة البحثية بـ (عدم وجود تصور محدد عن الطرق والآليات والمستويات والأهداف لتحقيق التكيف للأنماط المعمارية بتغير المؤثرات الطبيعية والحضارية. ولحل مشكلة البحث تبنى البحث المنهج المتمثل ببلورة إطار نظري يضم مجموعة من المفردات الرئيسة تمثلت بالأتي: المفردة المعمارية المعنية بالتكيف، الهدف من عملية التكيف، نوع المؤثر المسبب للتكيف، الطرق والآليات المستخدمة لتحقيق التكيف، وذلك بالاستعانة بالدراسات المعمارية التي تناولت هذه المفردات.الكلمات الدالة: التكيف، النمط، التحولات النمطية، التعديل

Abstract

AbstractThe present study was carried out to investigate the effect of 5 cleaning agents(dettol soap, whitening tooth paste, sodium bicarbonate powder, and ethanol handsanitizer gel and siwak powder) on color alteration of heat-polymerized acrylic resinand to compare it with that of distilled water. 60 specimen strips of heat-polymerizedacrylic resin material were prepared measuring 5mm width, 40mm length and 2mmthickness; five specimens were used for each group. After two weeks of immersion intea solution, the light transmission percent value for each specimen was determined at400nm and 700nm wave lengths by a spectrophotometer device.Then the half of the stained specimens were cleaned by the cleaning agents bybrushing with a hand brush , and rest specimens were cleaned by the same cleaningagents by an electrical dental brush and again measure the light transmission percentvalue for each specimen by the spectrophotometer device.The result obtained in this study showed that ethanol gel specimen group has thehighest mean value for light transmission among all the specimen groups of hand andmotor brush at the two wave lengths, followed by tooth paste, siwak powder, sodiumbicarbonate powder & dettol soap groups but distal water group has the lowest one.Furthermore, there were no measurable differences between the hand brush and theelectric tooth brush with respect to staining removal from the acrylic resin specimensfor all cleaning agents groups used in this study.

Abstract

This transmission electron microscopy (TEM) study has shown that the all of sections were obtained from tapeworm, Hymenolepis nana infection which were administered by eggs to white mice at 28 days of age, except in the case of cortisone- treated mice, in which infection was carried out at 38 day of age . The appearance of the brush border does not vary with the age of the worm, nor does treatment with cortisone affect it . The same may be said of distal cytoplasm . There is, however, a dramatic change in the appearance of the perinuclear layer . In older worms (45 day) the number of nuclei is reduced and those which remain are dark in colour . Unidentified structures, which appear to be abnormal, granulated mitochondria, are seen, and lipids accumulate both within and around the cells . Older worms from with cortisone - treated mice also have an altered perinuclear layer, but the changes are different . All of the normal structure are present, but they look as though they are dying because their membranes have a tendency to collapse . As in older worm from hosts which were not treated with cortisone, there was an increase in oil droplets .
