The effect of various nitrogen fertilizers on zinc (zn) availability in non calcic brown forest soils

In this article the effect of different nitrogen fertilizer application on the availability of zinc (Zn) content in non calcic brown forest soil was investigated. For this purpose increasing rates of NH₄Cl, (NH₄)₂S0₄; NH₄N0₃ and Ca(N0₃)₂.4H₂0 fertilizers were applied for having different physical and chemical properties in two soil samples. An incubation experiment was carried out over 4 months. The available Zn content of the soils was determined each month. According to the results the highest available Zn content of the soils was obtained from NH₄Cl applied to the soils followed by (NH₄)₂S0₄; NH₄N0₃ and Ca(N0₃)₂.4H₂0 application to soil. At the end of the experiment the average available Zn content of non calcic brown forest soils for NH₄Cl, (NH₄)₂S0₄; NH₄N0₃ and Ca(N0₃)₂.4H₂0 fertilizers are 0.93, 0.91, 0.88 and 0.77 mg kg^?1, respectively.     

Investigation of the genetic diversity among native Turkish sheep breeds using mtDNA polymorphisms

A total of 135 unrelated sheep from nine Turkish native sheep breeds (Dagl?c, Kivircik, Imroz, Chios, Morkaraman, Ivesi, Hemsin, Karayaka and Akkaraman) were investigated to determinate the maternal genetic diversity using a sequence of a 531-bp segment of the mtDNA control region. Analysis of the mtDNA control region sequence revealed 63 haplotypes and 53 polymorphic sites. Haplotype diversity, nucleotide diversity and the average number of nucleotide differences were estimated to be 0.9496?±?0.011, 0.01407?±?0.00060 and 7.456, respectively. The sequence analysis also revealed high level of genetic diversity among the native Turkish breeds. These breeds were grouped into three major maternal haplogroups: A, B and C, with one animal belonging from the Akkaraman breed to the rare haplogroup E. Irregular shape of mismatch distribution of haplogroup C could be an indicator that haplogroup C may represent different haplogroups. Contrarily to previous studies carried out on Turkish native breeds, majority of animals grouped in haplogroup A in the present study. This result and the irregular shape of mismatch curve of haplogroup C indicate that genetic structure of Turkish native sheep breeds could be more complicated than it is thought.     

Wettability and roughness characteristics of modified wood boards using a hot-press

The aim of this study was to investigate the effect of the thermal modification process by hot-press on the wettability and surface roughness characteristics of the eucalyptus wood boards. The roughness measurements, average roughness (R_a), and maximum roughness (R_max) were taken both parallel and perpendicular to the grain using a fine stylus tracing technique. Contact angle measurements were obtained using a goniometer system connected to a digital camera and computer system. The results showed that surface roughness values of the modified wood boards using a hot-press significantly decreased with increasing press pressure and with decreasing temperature. The contact angle measurements indicated that the thermal modification had a significant influence on the surface wettability of the wood boards. Statistical analyses showed significant differences in the surface roughness and contact angle values of the wood boards following thermal modification. The results acquired in this work provide important information for future research and utilization of the thermally modified wood boards.     

COMPARISON OF CLINICAL, ULTRASONOGRAPHIC, AND POSTOPERATIVE MACROSCOPIC FINDINGS IN COWS WITH BURSITIS

Clinical, ultrasonographic, and macroscopic findings of bursitis in cows were compared to assess the contribution of diagnosis and therapy planning. Sixteen dairy cows with swelling at the carpal (n = 12) or tarsal (n = 4) region were examined clinically and ultrasonographically and the findings were compared. In 10 patients the bursae were removed in toto. According to the duration of the disease (history) and clinical findings nine and seven patients had acute and chronic bursitis, respectively. Six had fluctuation and in 10 the bursa was firm. Contents were serous (n = 3), serofibrinous (n = 4), serohemorrhagic (n = 2), or purulent (n = 1). Sonographically there was fluid in all bursa except one. Capsule echogenicity varied between hypoechoic and hyperechoic and mean capsule thickness was 9.2 +/- 4.1 mm. Fourteen of the bursae contained free-floating particles. The hyperechoic capsules represented fibrous tissue, and the echogenic/hyperechoic free-floating particles were erythrocytes, purulent exudate, or fibrin masses. Capsule thickness and large free-floating particles could not be detected by clinical examination/centesis alone. However, capsule thickness, bursa contents, and the extent of inflammation could be determined ultrasonographically and this made the decision for different invasive/ operative procedures easier.     

A comparative study on performance properties of yarns and knitted fabrics made of biodegradable and conventional fibers

Biodegradable products are parts of a natural cycle. The biopolymers and the fibers that can be produced from them are very attractive on the market because of the positive human perception. Therefore, PLA being a well known biodegradable fiber and some conventional fibers were selected for the current study to examine the differences between them and to emphasize the importance of biodegradability beside fabric performance. 14.8 tex (Ne 40/1) combed ring spun yarns produced from biodegradable fiber PLA, new generation regenerated fibers Modal and Tencel, synthetic and blends 50/ 50 % cotton/polyester and 50/50 % viscose/polyester, polyester were selected as yarn types and by using these yarns, six knitted fabrics were produced and some important yarn and fabric properties were compared. In this context, moisture and the tensile behavior of yarns and pilling, bursting strength, air permeability and moisture management properties of the test fabrics are discussed.     

Severe abdominal dog bite wounds in a pregnant cat

Bite wounds are one of the most common reasons for admission of cats to veterinary clinics. Appropriate wound management seems to be more important in the successful outcome of bite wound injuries than antibiotic therapy alone. This report describes a heavily pregnant cat that suffered severe abdominal bite wounds necessitating treatment with extensive surgery. A necrotic herniated kidney, abdominal wall hernias, internal peritoneal ruptures and fracture of the thirteenth rib, gravid cornu rupture, an extrauterine dead foetus and its free kidney were all observed at laparotomy. At surgery the extrauterine dead foetus was removed, and two live foetuses were retrieved by en bloc ovariohysterectomy. A right nephrectomy and partial costectomy were also performed. Two weeks postoperatively, the cat had fully recovered without a problem. Bite wounds encountered in cats, though severe and invasive, can be tolerated and extensive surgical management can result in successful outcomes even under suboptimal conditions.     

Ultrasonographic and macroscopic comparison of the thickness of the capsule,corium, and soft tissues in bovine claws: an in vitro study

This study aimed to compare thickness of the capsule, corium, and soft tissues measured ultrasonographically and macroscopically in selected regions of bovine claws. A hundred and twenty claws (n = 120) of 15 healthy Holstein bovines were obtained. After cleaning the claws, ultrasonographic measurement of the capsule, corium, and soft tissues was performed while submerging the claws in a water bath. Macroscopic measurements were taken after cutting of the claws axially. These values were compared statistically. According to the macroscopic measurements, the mean thickness ± standard deviation (SD) of the capsule for dorsal wall and sole was 6.2 ± 0.1 and 9.5 ± 0.4 mm, respectively. The thickness of the corium and soft tissues for dorsal wall and sole was 4.5 ± 0.1 and 5.3 ± 0.1 mm, respectively. Ultrasonographically, the mean thickness ± SD of the capsule for dorsal wall and sole was 4.7 ± 0.1 and 7.8 ± 0.3 mm, respectively. The thickness of the corium and soft tissues for dorsal wall and sole was 4.3 ± 0.1 and 5.9 ± 0.2 mm, respectively. Findings demonstrated that ultrasonography can be reliably to measure of the thickness of the hoof capsule, corium, and soft tissue in bovine claw.     

Modified Colostomy Technique for Colonic Atresia in Calves

Objective: To report a modified colostomy technique for permanent fecal diversion in calves with colonic atresia. Study Design: Prospective study. Animals: Calves (n=19) with colonic atresia. Methods: Clinical findings, white blood cell counts, radiologic, ultrasonographic, and intraoperative findings were recorded. Calves were randomly divided into 2 groups: group 1 (n=9) had conventional colostomy and group 2 (n=10) had a modified colostomy. Technique efficacy was evaluated by postoperative observation, owner satisfaction, and calf survival. Results: Fifteen (79%) calves were discharged from the hospital; 4 (21%) group 1 calves died within 24 hours after surgery. Two (40%) group 1 calves died 18 and 30 days after surgery and 5 (50%) group 2 calves died 2–60 days after surgery. Eight calves reached slaughter weight (120±10 kg); 5 group 2 calves grew normally but the 3 group 1 calves had lower weight gain. Owners of the calves with conventional colostomy reported that the evacuation of feces was continuous whereas owners of calves with the modified colostomy reported that feces were released through the stoma in intervals. Conclusion: Modification of conventional colostomy by forming an hourglass shaped stoma lessens fecal incontinence but there was no difference in survival rate. Clinical Relevance: Modified colostomy was considered advantageous because of intermittent fecal discharge from the stoma compared with continuous fecal release in conventional colostomy. The modified technique seemingly has a beneficial effect on growth of the calf.     

Wettability and surface roughness of thermally modified plywood panels

The objective of this research was to investigate the wettability and surface roughness properties of the plywood panels under thermal modification. The plywood panel specimens were subjected to thermal modification under atmospheric pressure and presence of air at a temperature of 150, 170 or 190 °C for 60 min. The contact angle measurements were obtained by using a KSV Cam-101 Scientific Instrument connected with a digital camera and computer system. The roughness measurements, average roughness (R_a) and maximum roughness (R_max), were performed based on both parallel and perpendicular to the grain using a fine stylus tracing technique. Statistical analyses showed significant differences in the surface roughness and contact angle values of the plywood panels following thermal modification.
