Normal values of haematological and some biochemical parameters in serum and urine of New Zealand White rabbits

[EN] The purpose of the present study was to define the normal haematologic values and some biochemical parameters in serum and in urine in both male and female New Zealand white rabbits and to determine the effect of gender on these parameters. Blood and urine samples from a total of 40 New Zealand white rabbits were investigated. The haematologic parameters were determined in whole blood samples, while serum and urine (urine protein, glucose, creatinine, urea, GGT, nitrite, Na, K, Cl, creatinine clearance) biochemical parameters were determined in serum and urine samples. Normal values of these parameters were determined and statistical comparisons between male and female animals performed. No statistically significant differences were found between male and female animals for the parameters analysed except HCT, HGB, granulocyte %, L/M and serum K concentration. As a result, it was judged that defining the normal values of given haematological factors and serum and urine biochemical parameters in this study in New Zealand white rabbits would be helpful for both clinicians and researchers.Özkan, C.; Kaya, A.; Akgül, Y.

Bioreaktör, windrow ve kapalı statik yığın kompostlaştırma yöntemlerinin değerlendirilmesi

06.03.2018 tarihli ve 30352 sayılı Resmi Gazetede yayımlanan “Yükseköğretim Kanunu İle Bazı Kanun Ve Kanun Hükmünde Kararnamelerde Değişiklik Yapılması Hakkında Kanun” ile 18.06.2018 tarihli “Lisansüstü Tezlerin Elektronik Ortamda Toplanması, Düzenlenmesi ve Erişime Açılmasına İlişkin Yönerge” gereğince tam metin erişime açılmıştır.Anahtar kelimeler: Geri kazanım, kompost, teknikler, atık, içerik, plastik Dünya nüfusunun gün geçtikçe artışı, şehirleşmenin hızlanması, teknolojinin ve endüstrileşmenin gelişmesi kaynaklı yoğun üretim ve tüketim çağı başlamıştır. Hız kesmeden artan üretim talepleri hammadde tüketiminin aşırılaşması ve tüketim sonucu ortaya çıkan atıkların her gün daha da büyük sorunlar haline dönüşmesi ciddi çevre sorunlarına neden olmaktadır. Bu çalışmada son zamanların en büyük çevre kirliliği kaynağı olan katı atıkların bertaraf sorunlarına çözüm olarak oluşturulmuş geri kazanım sistemleri içerisinde en hızlı ve en aktif sistem olan kompostlaştırma ele alınmıştır. Kompostlaştırma ile geri kazanım hem çevresel sorunları çözmekte en kolay erişilebilir bir uygulama hem de diğer yöntemlere göre ekonomik getirisi çok yüksek bir yöntemdir. Çalışmada günden güne artan teknolojik ilerlemeler ile öne çıkmaya ve pratikte de uygulamaları yaygınlaşmaya başlamış olan üç ayrı kompostlaştırma yöntemi incelenmiş ve kıyaslanmıştır. Biyoreaktör, Windrow ve kapalı statik yığında (Tünel) kompostlaştırma yöntemleri değerlendirilerek bu yöntemlerle işletilen tesislerde hammadde, verimlililik ve sürdürülebilirlik konuları irdelenmiştir. Dünyamızda son on yılda üretimi, kullanımı ve buna bağlı olarak çevredeki atıkları katlanarak artmakta olan ve parçalanması için yüzyıllar gereken plastik atıkların, kompostlarda bulunma ihtimali dikkate alınarak bazı analizler yapılmış ve yaklaşımlarda bulunulmuştur. Plastik parçacıklarının (nano, mikro ve mezo boyutta) kompost hammaddesi ve olgun kompostta bulunması durumunda çevrede oluşturabileceği riskler sürdürülebilirlik açısından değerlendirilmiştir.Keywords: Recycling, compost, techniques, waste, content, plastic The intensified production and consumption era started with the increasing population of the world, accelerating urbanization, and the development of technology and industrialization. Increasing production demands, the excessive increase in raw material consumption and the wastes resulting from consumption becoming a bigger problem cause serious environmental issues. In this study, composting, which is the fastest and most active system of Recycling Systems, is considered as the solution to the problem of disposal of solid wastes, which is the biggest source of environmental pollution recently. Recycling by composting is an easily accessible application to solve environmental problems and is a highly economical method compared to other methods. This study examined and compared three composting methods which have started to stand out with advancing technological developments and become popular in practice. Bioreactor, Windrow and closed static mass (Tunnel) composting methods were investigated, and subjects of raw material, productivity and sustainability at facilities using these methods were addressed. Certain analyses were made and approaches were evaluated based on the possible presence of plastic wastes, which have been increasing in the environment due to production and usage in the last decade and take centuries to degrade, in composts. Risks that may be posed on environment by plastic particles (in nano, micro and meso sizes) in case of being in the compost raw material and mature compost were evaluated in terms of sustainability

Clinical Coenurosis (Coenurus Cerebralis) and Associated Pathological Findings in a Calf

This study aims to investigate clinical and pathological findings of a clinical Coenurus cerebralis case in a 10-month-old Simmental male calf. Clinical examination of the calf revealed incoordination, irregular gait, failure to hold the head straight, leftward head tilt, and circling. The animal was diagnosed with C. cerebralis and euthanazia was recommended. The autopsy demonstrated a cyst (9x7 cm) in the caudal of the left cerebral hemisphere within the cranium. The cyst caused compression over the ventral portion of the left cerebral hemisphere, while a marked perforation of 3-4 cm diameter was found on the sphenoid bone. Histopathologically, hyperemia and perivascular mononuclear cell infiltration were observed. In conclusion, we found it beneficial to present the clinical and pathological findings of this calf infected with C. cerebralis which is known to be a rare clinical entity among cattle

Comparison of Hydrothermal Method and Ultrasonic Method in Zeolite Synthesis and Investigation of Catalytic Activities of Synthesized Zeolites

In this study, ZSM-5 and beta zeolites, which constitutes the most industrially important artificial zeolite species., were synthesized and the effects of synthesized zeolite in catalytic cracking were investigated. ZSM-5 and beta zeolite were synthesized by varying synthesis time, synthesis method and calcination temperatures. The composition of the synthesis was kept constant and than compared with ultrasonic method and hydrothermal method. ZSM-5 and beta zeolite derivatives were synthesized with changing the synthesis method. Beta zeolite is obtained as a result of the synthesis with low temperature in 20 minutes with using of ultrasonic method. On the other hand, ZSM-5 zeolite is achieved at the end of the synthesis with high temperature in 72 hours with using of hidrotermal method. The X-Ray Powder Diffraction (XRD) patterns and Scanning Electron Microscopy (SEM) images of ZSM-5 zeolites showed that the crystal structure and phase purity of ZSM-5 increased with increase in synthesis time and not affected by the calcination temperature. Otherwise, the crystal structure and phase purity of beta zeolite increased with increase in calcination temperature. To determine the catalytic performances of the products, the catalytic cracking processes were performed. First of all, thermal cracking was realized without catalyst for comparison with the others. Then, catalytic cracking was carried out with CaO, Al2O3, SiO2, natural zeolite, ZSM-5 and beta zeolite. Compairing the results, the catalytic efficiency of the synthesized products were higher than the others. Yield of over 70 % was obtained with synthesized ZSM-5 and zeolite beta
