In this study, the electric current of polymer solution jet was measured during a needleless rod electrospinning process using memory oscilloscope recording. According to the results, electric current of solution jet increases as the polyurethane (PU) and tetraethylammonium bromide (TEAB) salt concentration increase. Especially at 17.5 and 20 wt% PU concentrations, electric current increases dramatically with TEAB concentration. Also, there is a strong relationship between the electric current in the solution jet, spinnability and the spinning performance of the roller electrospinning. Thus, the spinnability of polymer solutions can be easily estimated using this simple method. 相似文献

The high radioactivity and trace elements in drinking water are common concerns for human health. The aim of this study was to investigate the eligibility of groundwater for drinking purpose in terms of both radioactivity and trace element contents in Eskisehir Region (Turkey). The study area is located in a highly populated residential area where water supply is mostly met from groundwater. The area is about 20,000 km2, where igneous, metamorphic, and sedimentary rocks are exposed. The 209 water samples collected from 84 water resources (including thermal waters) were analyzed with respect to major ions, trace elements, and radioactivity (gross alpha and gross beta) during both in wet and dry seasons. Based on the analysis results, trace elements in 49 samples of 84 water resources were over the limits of Code TS 266 1997 (Turkish Drinking Water Standards) and WHO 1993 standards. Particularly, Fe, Mn, Al, As, Ba, Zn, Cr, Cu, and B ion concentrations exceeded the limits. The gross alpha values in 18 locations and gross beta values in three locations also exceeded the limits of aforementioned standards in terms of radioactivity (gross alpha?=?0.1 Bq L?1; gross beta?=?1 Bq L?1). Furthermore, water radioactivity levels were close to the allowable limits in 33 water resources. The obtained results explicitly indicate that there is a strong relationship between the higher radioactivity–trace element contents and geochemical composition of rocks, which controls the radioactivity and trace element concentrations present in the aquifer. 相似文献

Canine hepatozoonosis is a disease caused by the tick-borne protozoan Hepatozoon spp. It has been reported in the United States, southern Europe, the Middle East, Africa and the Far East. In Turkey, canine hepatozoonosis was reported for the first time in 1933. In the present study, serum glutathione (GSH), malondialdehyde (MDA), nitric oxide (NO) and ceruloplasmin levels were analysed in 14 dogs infected with Hepatozoon canis as well as in 10 healthy dogs. Blood smears were prepared from peripheral blood and ticks were collected for identification in the laboratory. Rhipicephalus sanguineus was found only on diseased dogs. No ticks were observed on healthy dogs. The diagnosis of H. canis is made mainly by the detection of gametocytes within neutrophils and monocytes. The haematological diagnosis was confirmed using PCR analyses by amplifying a partial 18S rRNA gene sequence of Hepatozoon spp. Infection was detected in 14 animals. Compared to controls, the serum GSH, MDA and NO levels in infected animals increased significantly (p<0.05, <0.01 for MDA), whereas the concentrations of ceruloplasmin in diseased animals remained unaltered. The results of the present study suggest that in dogs infected with H. canis increased levels of GSH, MDA and NO may be related to host's defences against parasitic infection. 相似文献

Of the goat population in Turkey, 98% of the goat population consists of hair goats. They are the prime breeds of goats and they can be bred in the Mediterranean, Aegean and Southeast regions of Turkey. Hair goats are the main income for their breeders. The goats are typically raised in scarce conditions, thus giving rise to greater yield of meat. In spite of the fact that the studies are limited to hair goats bred by the public, in 2005, Republic of Turkey Ministry of Food, Agriculture and Livestock (TAGEM) initiated a countywide reclamation project aiming to identify the regional differences and characteristics of the hair goats. This paper focuses on the yearly quantity of hair goats' produce, particularly observing the proportions of goat milk, meat and other animal produce, and to highlight the importance of the hair goats. Recommendations are made from these findings. 相似文献

We have examined the effects of Tribulus terrestris (TT), a non-toxic herb, on sex reversal in the Convict Cichlid Cichlasoma nigrofasciatum with the aim of introducing a new environmentally friendly method for masculinization in C. nigrofasciatum. TT is a natural plant product that elevates the testosterone levels in humans and animals. Different concentrations (0.0,
0.10, 0.20 and 0.30 g/l) of TT extract were tested for their effect on sex reversal in C. nigrofasciatum by immersing newly hatched offspring once weekly for 2 months in TT extract. Of the dosages used in the present study, 0.30 g/l
TT was the most effective in terms of masculinization, resulting in a maximum male ratio of 87.23% (P < 0.001). Sex ratios of 79 and 85% at 0.10 and 0.20 g/l TT, respectively, were also significantly different from the expected
1:1 ratio (P < 0.001). Histological examinations revealed that the testes of fish treated with TT extract contained all stages of spermatogenesis,
clearly demonstrating that the administration of TT extract to C. nigrofasciatum stimulated spermatogenesis. Total survival rates in all treatments and the control were uniformly high, ranging from 88.57
to 90% (P > 0.05). We concluded that TT had no negative effect on the survival rate of C. nigrofasciatum. In addition, all groups of TT-treated fish exhibited successful growth acceleration compared to the control group, but only
the 0.30 g/l TT treatment significantly improved the growth rate of C. nigrofasciatum. (P < 0.01). Sex reversal in C. nigrofasciatum demonstrated that TT-treated 0-day-old larvae showed successful sex reversal, spermatogenesis and a better growth rate than
untreated progenies. 相似文献

This study was carried out to compare the fattening performance and carcass traits of Chios male lambs fed under traditional
and intensive feeding conditions. In the study, a total of 34 lambs were randomly separated into traditional (T) and intensive
(I) groups in equal numbers. Lambs in group T were fed on ration prepared in local style and grazed in olive grove for 8 h/day.
On the other hand, lambs in group I were fed on 255 g alfalfa hay animal−1 day−1 and ad libitum mixed feed. After a period of 8 weeks, lambs were transported to the slaughterhouse. The results showed that
Chios lambs fed under intensive conditions has better performance and produced heavier carcass compared to those fed under
traditional conditions. However, consumption of concentrate feed mixture was about twice as much in group I as in group T.
Total feed consumption and feed conversion ratio was similar in each group. The values of carcass traits of lambs in group
I were found to be significantly higher than those of group T. On the other hand, carcass fat thickness was slightly lower
in group T. Traditional condition is considered to respond to better to consumer demands for lean lamb carcass. 相似文献

The research was conducted in two successive seasons to compare the effect of nutrient sources, organic manure and inorganic conventional nutrient solution, in cucumber production performed with different local substrates. In fall, the experiment was designed to test three factors, namely cultivar [(a) Armada, (b) Gordion], nutrient source [(a) inorganic nutrient solution, (b) solid organic manure] and substrate [(a) 3 + 1 perlite + clinoptilolite, (b) 1 + 1 perlite + clinoptilolite, (c) 3 + 1 tuff + clinoptilolite, (d) 1 + 1 tuff + clinoptilolite, v/v]. Results showed that organic manuring decrease the total yield by 22.4% in comparison to inorganic nutrient solution. In organic manure treatment, vigorous variety (Armada) gave higher yield than less vigorous variety (Gordion). In the spring season, the tested factors were decreased to two and tested as nutrient source [(a) inorganic nutrient solution, (b) solid organic manure, (c) organic nutrient solution] and substrate. Armada was the only cultivar. Compared to that of the inorganic nutrient solution, total yield was reduced by 10.9% in the organic nutrient solution system and 31.3% in solid organic manure treatment. 相似文献

Rectal swabs from 100 dogs that were admitted to the veterinary clinic and from randomly selected 100 dogs from one kennel were examined for the presence of Salmonella spp. S. Enteritidis was isolated from a household dog and the strain was susceptible to all antibiotics that were tested. S. Typhimurium was isolated from a dog from the kennel and it was sensitive to all the antibiotics except streptomycin and neomycin. Even though, the occurence of Salmonella spp. in the feces of the dogs in this study was low, attention should always be given when handling canine feces or contaminated materials. 相似文献
