A 15‐year‐old male dromedary camel with a history of chronic severe keratoconjunctivitis and corneal mass in the left eye of 6 months’ duration was referred to the Veterinary Medical Teaching Hospital at Adnan Menderes University. A superficial keratectomy was performed and biopsy material submitted for histopathology. The diagnosis was corneal papilloma. There has been no recurrence of the neoplasm to date (6 months, 1 year). Corneal papilloma has not been reported previously in camels and seems to be associated with papillomavirus. 相似文献

Common ragweed invasion poses serious risks to human health, biodiversity and agricultural production throughout the world. Although ragweed has an enormous potential to expand its range in Turkey, studies on ragweed have only concentrated on the Black Sea region. An exploratory survey was conducted to observe the level of ragweed occurrence on the nodes of predecided 10 × 10 km grids in the Thrace region of Turkey. Ragweed populations were observed in 44 out of 129 sites in a wide range of habitats, including roadsides, pastures, agricultural fields and non‐agricultural areas. The highest levels of ragweed infestation were recorded in the agricultural fields, followed by the roadsides. The most‐invaded crop was sunflower. The sunflower fields had the highest ragweed coverage as well and invasion even resulted in crop failure alongside the field borders. A spatial analysis of the data indicated that ragweed exhibited an aggregated pattern over the Thrace region. Ragweed distribution was not associated with the characteristics of the soils, which had a varying range of pH, electrical conductivity and texture. The results revealed that ragweed invasion can arise as a serious weed problem, interfering with the sustainability of sunflower production in Thrace and other sunflower‐producing regions of the country. A high degree of ragweed infestation also will contribute to the pollen level counts for the most crowded cities in the region, posing a serious danger to human health. 相似文献

Seven grades of black tea [high-quality black tea (grades 1-3) and low-quality black tea (grades 4-7)], processed by ?AYKUR Tea Processing Plant (Rize, Turkey), were examined for their proximate composition, dietary fiber, minerals, and water-soluble vitamins as well as total phenolic content, various antioxidant assays, phenolics (flavanols, alkoloids, condensed phenolics, and phenolic acids), chlorophylls, and carotenoids. Some variations, albeit to different extents, were observed (p < 0.05) among these parameters in seven grades of black tea. With respect to proximate composition, dietary fiber was the predominant compound (ranging from 49.68 to 54.31 g/100 g), followed by protein, carbohydrate, and, to a lesser extent, ash, moisture, and fat. Thirteen minerals, four water-soluble vitamins, six flavanols, two alkoloids, three condensed phenolics, one phenolic acid, two chlorophylls, and two carotenoids were identified in the seven grades of black tea. Total phenol content ranged from 7.52 to 8.29 g of gallic acid equivalents (GAE)/100 g, being lowest in grade 6 and highest in grade 1. With regard to antioxidant activities, a large variation in oxygen radical absorbance capacity (ORAC) values was observed among all grades of black tea (ranging from 777 μmol of trolox equivalents (TE)/g in grade 7 to 1210 μmol of TE/g in grade 3). The present work suggests that high- and low-quality black teas should not be distinguished on the basis of their nutritional and functional characteristics. The combination of nutritional compounds together with functional characteristics renders combination effects that provide the characteristic quality of each grade of black tea. 相似文献

The effects of the reaction temperature and varying level of weight gain on the dimensional stabilisation of crotonic anhydride
modified Corsican and Scots pine sapwood were investigated. With Corsican pine at low levels of substitution, the reagent
occupied larger molar volumes in the cell wall than at higher weight gains. With Scots pine the molar volume occupied by reagent
was found to be temperature dependent at low levels of substitution. Dimensional stabilisation was determined by the water-soak/oven-dry
method through a total of ten cycles in order to determine the stability of the ester bond to hydrolysis at neutral pH. It
was found that the reaction temperature has no significant effect on dimensional stability provided the same weight gain level
is obtained. At weight gain levels in excess of 30%, values of anti-shrink efficiency of 90% were obtained.

The objectives of this study were to quantify the amount of the stream discharge, nutrient fluxes, suspended sediment loss,
and to define the relationship between streamflow and these parameters in a forest-covered watershed. The study was carried
out in an experimental watershed, which has been monitored since 1979 in the Belgrad forest in Istanbul. Significant linear
regressions were obtained between streamflow and discharge of selected water quality parameters. Mean monthly losses were
10.01 kg/ha for HCO3
−, 5.92 kg/ha for CI−, 0.07 kg/ha for total N, 1.29 kg/ha for Mg2+, 3.59 kg/ha for Ca2+, 2.59 kg/ha for Na+, 1.82 kg/ha for K+, 0.0113 kg/ha for P-PO4
3−, and 35.82 kg/ha for suspended sediments. Among the monitored water quality parameters, HCO3
−, CI−, and Ca2+ had greater losses than the rest of the chemical parameters studied in the watershed. Net gains (influx exceeded outflux)
calculated for total N, Mg2+, K+, and P-PO4
3− in the annual basis can be considered as an addition to the ecosystem’s organic nutrient pool. In contrast, net losses occurred
for HCO3
−, CI−, Ca2+, and Na+. 相似文献

The vine bud moth, Theresimima ampellophaga (Bayle-Barelle 1808) (Lepidoptera: Zygaenidae; Procridinae), is a pest on grape vine, Vitis vinifera (L.), and on the ornamental vine Parthenocissus quinquefolia (L.) and other Parthenocissus species. Its recent distribution in Europe is relatively well known, but there is a paucity of locality data for Turkey. As a consequence, we began a large-scale investigation into its distribution and seasonal activity in this country in 2008. The main tools for these investigations were pheromone traps that were baited with the synthetic pheromone of the species, viz. (2R)-butyl (Z7)-tetradecenoate. As a result of field work carried out in the eastern Mediterranean region of Turkey in 2008 and 2009, Th. ampellophaga was recorded in five provinces, viz. Adana, Mersin, Hatay, Kahramanmara? and Kilis. The only province where the pest was not found was Gaziantep. Theresimima ampellophaga produces one or two generations per year, depending on the local conditions and other unknown factors. The moths of the first generation fly in June, while those of the second generation occur in August. To the best of our knowledge the present paper provides the first well-documented evidence of the occurrence of a second generation of the vine bud moth in Turkey. 相似文献

Planning effective weed control in cropping systems requires exact appraisal of the weed intensity and duration of their competition with the crops. This 2‐year study was carried out in order to determine the critical weed control period in sesame fields. Related and relative crop yields were monitored and analyzed using a four‐parametric log‐logistic model. We recorded data from weed‐free plots and compared these with data from different periods of weed interference. In both the study years, the longer period of weed interference decreased the relative yield of sesame, whereas the yield was increased with increasing duration of the weed‐free period. A 51–78.7% decline in sesame yield was noted if the weeds were allowed to compete with the crop from planting to harvest. In the first year, the duration of the critical period for weed control (CPWC) was 177–820 growing degree days (GDD), which corresponded to 14–64 days after crop emergence (DAE), and between 170 and 837 GDD (13–64 DAE) in the second year; this was based on a 5% acceptable yield loss. The results of this study clearly elaborated that maintaining weed‐free conditions is compulsory from as early as the second week after the emergence of sesame plants, and this should be maintained at least until the ninth week to avoid sesame yield losses by more than 5%. These findings show that growers can benefit from CPWC to improve weed control in sesame production, including the efficacy of a weed control program and its cost. 相似文献

The knowledge on the critical crop-weed competition period is important for designing an efficient weed management program. Field studies were conducted in 2012 and 2013 at the Agricultural Research Institute, Kahramanmaras, Turkey to determine the effects of three row spacing (50, 70 and 90 cm) on the critical period for weed control (CPWC) in cotton. A four parameter logistic equation was fit to data relating relative crop yield to both increasing duration of weed interference and length of weed-free period. The relative yield of cotton was influenced by the duration of weed-infested or weed-free period, regardless of row spacing. In cotton grown at 50 cm row spacing, the CPWC ranged from 117–526 growing degree days (GDD) (V2–V11 growth stages) in 2012 and 124–508 GDD (V2–V10) in 2013 based on the 5% acceptable yield loss level. At 70 cm row spacing, the CPWC ranged from 98–661 GDD in 2012 (V2–V13) and 144–616 GDD (V2–V12) in 2013. At 90 cm row spacing, the CPWC ranged from 80–771 GDD in 2012 (V1–V14) and 83–755 GDD (V1–V14) in 2013. In order to obtain a 95% weed-free yield, the weed management should start at 16 days after crop emergence (DAE) and continued until 52 DAE (V2–V11) for crops grown in 50 cm row spacing, 15 and 60 DAE (V2–V13) for 70 cm row spacing and 11 and 67 DAE (V1–V14) for crops grown in 90 cm row spacing. This suggests that cotton grown in narrow row spacing (50 cm) had greater competiveness against weeds compared with wider row spacing (70 and 90 cm). Cotton growers can benefit from these results by improving cost of weed control through better timing of weed management. 相似文献
