S. Yalçin  İ. Oğuz  S. Ötleş 《British poultry science》1995,36(3):393-399

1. The present study was conducted to evaluate the relationship between slaughter ages and carcase characteristics of Japanese quail.

2. Chicks were slaughtered at 5, 6, 7, 8 and 9 weeks of age. Carcase yield, carcase parts weight, weight of liver, heart, gizzard and alimentary tract were obtained. Protein, fat, dry matter and ash contents of meat were analysed for each sex.

3. Body weight and eviscerated weight were affected by age. Age had no significant effect on the weight of liver, alimentary tract, gizzard and heart. Age had first and second order polynomial effects on breast weight and relative leg weight. Meat compositions of leg and breast were significantly affected by age.  相似文献   

Can diphenhydramine prevent organophosphate-induced acute pancreatitis? An experimental study in rats     

Yusuf Yürümez  Yücel Yavuz  ?. Hakk? Çiftçi  Mehmet Emin Büyükokuro?lu 《Pesticide biochemistry and physiology》2007,87(3):271-275

Acute pancreatitis (AP) is a well known complication of organophosphate (OP) poisoning and the true incidence is unknown; but, may be more common than clinically suspected. Previous studies suggest that Diphenhydramine (DPH) may be useful as an alternative or adjunctive therapy in OP poisoning. The aim of this experimental study was to investigate whether DPH could prevent or diminish pancreatic damage caused by OP poisoning as defined by histologic findings, and serum interleukin 10 (IL-10) and tumor necrosis factor alpha (TNF-α) levels. Twenty-four Sprague- Dawley rats were divided into equal three groups. Group 1 did not receive any agent during the experiment. Group 2 received 0.8 g/kg fenthion subcutaneously followed by 3 ml/kg normal saline intramuscularly, 30 min later. Group 3 received 0.8 g/kg fenthion subcutaneously, followed by 30 mg/kg DPH intramuscularly, 30 min later. Twenty-four hours later, pancreatic tissues were excised and blood samples were taken. After blood samples were taken by cardiac puncture, the animals were sacrificed. Treatment with DPH significantly decreased the serum TNF-α and increased the serum IL-10 levels. DPH significantly reduced pancreatic damage, including edema, inflammation, vacuolization and necrosis, as determined by pathologic scoring. The present study show that DPH decreased the severity of OP induced AP in rats. This effects may be related to a decrease of TNF-α level and increase of IL-10 level.  相似文献   

Borax Production from Borax Slime, an Industrial Waste     

Recep Boncukcuoğlu  M. Muhtar Kocakkerim  Mahir Alkan 《Water, air, and soil pollution》1998,104(1-2):103-112

Borax slime is formed during the production of borax from tincal, which is an important borate ore. It is a liquid containing the suspanded solid particles at high levels and is formed under the rich-in-borax solution in the reactor. This waste is discharged into the Marmara Sea and so causes environmental problems in Band?rma Golf. In this work, Borax production is aimed from the slime containing B₂O₃ at important levels. As a result it was found that B₂O₃ can be recovered and therefore the B2O3 pollution can be prevented by removing it from the waste.  相似文献

Dantrolene may prevent organophosphate-induced oxidative stress and muscle injury     

Mehmet Emin Büyükokuro?lu  Mustafa Cemek  Yusuf Yürümez  Yücel Yavuz 《Pesticide biochemistry and physiology》2008,92(3):156-163

The effects of dantrolene against fenthion-induced oxidative stress and muscle injury were investigated in rats. Malondialdehyde (MDA), reduced glutathione (GSH) ascorbic acid, retinol and β-carotene levels in blood were measured. Histopathological alterations and apoptosis in diaphragm were examined. Fenthion increased the level of MDA and decreased the levels of GSH in blood. Dantrolene administration prevented the rise in MDA levels and increased the GSH levels. There was no significant difference between β-carotene levels of experimental groups. However, fenthion toxicity led to decrease in ascorbic acid and retinol levels, dantrolene administration significantly prevented this decrease. Dantrolene significantly decreased the inflammation, edema and muscle necrosis or apoptosis in diaphragm muscle. Results of present study showed that toxicity of organophosphate compound fenthion increases the lipid peroxidation and depresses endogenous antioxidative systems, and leads to muscle injury in organism. Again, dantrolene administration prevents lipid peroxidation, augments antioxidant activity, and decreases muscle injury and apoptosis.  相似文献   

Developing and implementing participatory and ecosystem based multiple use forest management planning approach (ETÇAP): Yalnızçam case study     

Emin Zeki Baskent  adan Bakaya  Salih Terziolu 《Forest Ecology and Management》2008,256(4):798-807

This paper explains the conceptual framework of ecosystem based multiple use forest management (ETÇAP) approach and its implementation in a case study area. The new management philosophy has four important pillars; integration of biodiversity conservation into forest management process, characterization and accommodation of multiple forest values, effective participation of stakeholders and the use of advanced information technologies and management science techniques. These components comprise a sound framework of a forest management planning system in Turkey as the ownership, land use policy, social structure and forest ecosystems are unique to the country. Among few implementation sites, some experiences from the case study area of Yanlızçam planning unit were documented to realize the performance of the concept. The liaison between the government institutions and major stakeholders is found necessary, and the effective use of geographic information system (GIS) and remote sensing (RS) have been realized critically important to better communicate among stakeholders and generate precise database and the plan. The case study indicated that structured participation is an effective communication tool and has a better possibly to promote multiple use forest management rather than using participation as solo information gathering process. Primary challenges relate to the effectiveness of national conservation program, availability of coherent biodiversity data and adequacy of institutional capacity that involve awareness, training and common understanding of biodiversity and protected area concept; coordination among the related institutions and stakeholders, and willingness and enthusiasm of authorities to accept and implement the concept.  相似文献   

The mechanism and/or prediction of the breaking elongation of polyester/viscose blended open-end rotor spun yarns     

Oğuz Demiryürek  Erdem Koç 《Fibers and Polymers》2009,10(5):694-702

In this study, an analysis on the breaking elongation mechanism of the polyester/viscose blended open-end rotor spun yarns has been carried out. In addition, a back propagation multi layer perceptron (MLP) network and a mixture process crossed regression model with two mixture components (polyester and viscose blend ratios) and two process variables (yarn count and rotor speed) are developed to predict the breaking elongation of polyester/viscose blended open-end rotor spun yarns. Seven different blend ratios of polyester/viscose slivers are produced and these slivers are manufactured with four different rotor speed and four different yarn counts in rotor spinning machine. In conclusion, ANN and statistical model both have given satisfactory predictions; however, the predictions of ANN gave relatively more reliable results than those of statistical models. Since the prediction capacity of statistical models is also obtained as satisfactory, it can also be used for breaking elongation (%) prediction of yarns because of its simplicity and non-complex structure. In addition, it is also found in this study that yarn count, rotor speed and breaking elongation of polyester-viscose fibers and the blend ratios of these fibers in the yarn have major effects on yarn breaking elongation.  相似文献

Topical and residual toxicity of six pesticides to <Emphasis Type="BoldItalic">Orius majusculus</Emphasis>     

Fatih Dağlı  Şerife Ünal Bahşi 《Phytoparasitica》2009,37(5):399-405

The toxicity of six pesticides (four insecticides and two fungicides) to Orius majusculus (Reuter) (Hemiptera: Anthocoridae) adults and nymphs was determined using different exposure methods. Mortality upon topical exposure to abamectin, endosulfan and spinosad at recommended field doses ranged from 56% to 100% after 24 h. However, in leaf residue tests, toxicity to both life stages decreased significantly, ranging from 0% to 33% mortality. Benomyl and copper salts + mancozeb (fungicides) were much less toxic to O. majusculus, with less than 15% mortality of either adults or nymphs in topical and residue bioassays. In persistent toxicity tests, insects were exposed to the same three insecticides for 4 days; mortality varied from 38% to 100%. Egg hatching was not significantly affected when abamectin, endosulfan and spinosad were topically applied. Number of eggs laid per female in choice and no-choice tests did not differ significantly from the control. The insecticides did not show considerable repellent effect in the choice tests. Topical, residue and systemic uptake methods were also compared to determine the differences in the toxicity levels of imidacloprid, a systemic insecticide. However, 100% mortality occurred with all methods.  相似文献
