Drought analysis in Antakya-Kahramanmara? Graben,Turkey     

Murat KARABULUT 《干旱区科学》2015,7(6):741-754

The most parts of the Earth experience precipitation variability as a part of their normal climates over both short- and long-time periods. These variations of precipitation will have unpredictable and perhaps unexpectedly extreme consequences(such as drought and flood) with respect to frequency and intensity for many regions of the Earth. Because of high precipitation fluctuations, the Mediterranean region is also the areas of the world sensitive to precipitation changes which often involve frequent drought conditions in Turkey. In this study, drought conditions at annual, seasonal and monthly time scales over the period of 1975–2010 were examined for Antakya-Kahramanmara? Graben which is located in the eastern part of the Mediterranean region of Turkey. Application of appropriate measures to analyze and monitor droughts is recognized as a major challenge to scientists involved in atmospheric studies. Standardized Precipitation Index(SPI) and cumulative deviation curve techniques were used to determine drought conditions. Results indicated that the study area presented a cyclic pattern of variations with alternating drier and wetter years. From analyses of annual, seasonal and monthly drought series it can be seen that precipitation characteristic of the area is changing. By the results, apparent wet and dry periods can be distinguished. This study also indicated that precipitation totals of winter, spring and summer seasons were slightly decreased during the study period. Drought frequency was increased especially for the northern part of the area in the last ten years. Drought periods were divided into 1982–1985, 1999–2002 and 2004–2008, respectively. According to our analyses, the time scale of 1999–2002 was the driest period in the most of the graben area. The study area, which covers agriculturally important fertile alluvial plains, will experience increasing pressure on its water resources because of its growing population and industry, ever-larger demands for intensive agricultural activities, and frequent drought events.  相似文献   

Mortality of Isaria farinosa and Beauveria bassiana on sunn pests Eurygaster integriceps and Eurygaster austriaca     

Murat Muştu  Fikret Demirci  Erhan Koçak 《Phytoparasitica》2014,42(1):93-97

The effects of Isaria farinosa (Holm.) and Beauveria bassiana (Balsamo) on adult stages of sunn pests Eurygaster integriceps Puton and Eurygaster austriaca (Schrk.) were investigated at 27±1°C, 95% r.h. and 16L:8D in the laboratory. Two concentrations, 1×10⁶ and 1×10⁸ conidia ml^-1, were used. Mortality of inoculated and non-inoculated adults was counted at 6, 9 and 12 days after treatment. Beauveria bassiana caused higher mortality of both species than I. farinosa. Neither caused significantly high mortality at 1×10⁶ conidia ml^-1. Both were more pathogenic at 1×10⁸ conidia ml^-1 and caused more than 85% mortality 12 days post treatment. Both were more pathogenic to E. austriaca.  相似文献

Dabak M  Dabak DO  Karapinar T  Bulut H 《The Journal of veterinary medical science / the Japanese Society of Veterinary Science》2012,74(1):125-128

The aim of the present study was to determine the vitamin D status in cattle with malignant catarrhal fever (MCF). Twelve cattle diagnosed as MCF and 6 healthy cattle (controls) were used in the study. Serum 1,25-dihydroxyvitamin D(3) (1,25-D), 25-hydroxyvitamin D(3) (25-D), calcium, phosphorus and parathyroid hormone (PTH) levels were determined as 96.83 pg/ml, 30.0 ng/ml, 2.19 mmol/l, 1.57 mmol/l and 15.21 pg/ml in MCF group and 42.33 pg/ml, 37.0 ng/ml, 2.43 mmol/l, 1.96 mmol/l and 36.08 pg/ml in controls, respectively. Although serum 1,25-D level in the MCF group was increased (P<0.01), serum calcium (P<0.01) and PTH (P<0.05) levels were decreased compared to the controls. The results suggest that there might be an interaction between vitamin D status and MCF.  相似文献   

Effect of triple pelvic osteotomy on the proximal femoral geometry in dysplastic dogs     

Sarierler M  Yildirim IG  Ocal MK 《Research in veterinary science》2012,92(1):142-146

Triple pelvic osteotomy (TPO) is one of the surgical procedures for use to try to reduce subsequent degenerative joint disease or modify the progress of hip dysplasia in young dogs. Joint force and pressure distribution were changed by this procedure. Therefore, the aim of this study was to find out whether the remodeling of proximal femur exists or not after TPO in dysplastic dogs. Ten femora from five young dysplastic mongrel dogs, treated unilaterally with TPO using 20° canine pelvic osteotomy plates, were used. One year after TPO, neck-proximal shaft angle, femoral head, neck, diaphyseal and mid-shaft diameters, total femoral, femoral neck axis, and intertrochanteric, femoral head offset lengths as well as the lengths from head center to lateral margin of greater trochanter and to proximal femoral axis were measured from the bone. The significant differences between treatment and control side were determined in Norberg angle, neck-proximal shaft angle, neck diameter, diaphyseal diameter, mid-shaft diameter, length from head center to proximal femoral axis and femoral head offset length. In conclusion, although small number of cases was used, it was determined that the aforementioned variables are affected by TPO. So, these variables may be supply additional information about the changes to the joint following TPO in dysplastic dogs.  相似文献

Comparison of Probe with Bath Ultrasonic Leaching Procedures for Preparation to Heavy Metal Analysis of Bio-Collectors Prior to Atomic Absorption Spectrometry     

Murat Güney 《Communications in Soil Science and Plant Analysis》2017,48(15):1741-1752

Both comparison and optimization of two sample preparation methods (probe and bath) based on leaching of lead (Pb), zinc (Zn), manganese (Mn) and nickel (Ni) from bio-collector sprouts (Pinus sylvertris L., Picea orientalis L., Thuja orientalis L.) under ultrasonic effect has been examined. The best analytical conditions influencing leaching such as sonication times, acid type, acid concentrations, ultrasound amplitude and sample position (wet, dry and grinding) were determined. Leachatants obtained upon sonication were directly nebulized into an air-acetylene flame for fast metal determination by atomic absorption spectrometry (AAS). Optimum conditions for ultrasonic metal leaching were as follows: a 15 min for probe or 30 min for bath sonication time, wet sample position, nitric acid (HNO₃) solvent, 1% (w/v) for probe or 2% (w/v) for bath solvent concentration and 20% amplitude for probe. Comparable results for the ultrasonic leaching with probe (UL-P) and the ultrasonic leaching with bath (UL-B) for metals in certified reference material and bio-collectors have been obtained. Besides, UL-P reduces the time required for all treatments with UL-B approximately from 30 min to 15 min. The accuracy of methods was tested either by comparing obtained results with those of ashing method (AM) or by application on a certified reference material (CRM-7, Tea Leaves). The recoveries of metals using CRM-7 ranged from 94% to 104% for UL-P and 91% to 101% for the UL-B. The precision variance either between UL-P and UL-B or UL-P and AM was not significant at 0.05 probability for all metals. The relative standard deviation % was obtained between 3.4–7.6% (n = 3) and 4.7–9.5% (n = 3) for UL-P and UL-B, respectively, depending on the analyte.  相似文献   

Evaluation of Analytical Methods for Boron Determination in Maize Shoots     

Hakan Çelik  Murat Ali Turan  Barış Bülent Aşık  Ali Vahap Katkat 《Communications in Soil Science and Plant Analysis》2017,48(21):2573-2581

For the comparison of the digestion and spectroscopic determination methods used to measure boron (B) concentrations in maize shoots, increasing doses of boron (0, 2.5, 5, and 10 mg kg^?1 B) were applied to soil and maize plants (Zea mays L.) cultivar “Euralis Es Armandi” (FAO 640). The plants were grown under greenhouse conditions. Dried and ground maize shoots were digested according to two digestion procedures of microwave and dry ashing. Boron concentrations were determined using spectrophotometer and inductively coupled plasma-optical emission spectrometry (ICP-OES). The concentrations of boron influenced statistically (p < 0.01) due to the B applications and analysis methods. Spectrophotometric measurement of B amounts of the samples prepared with microwave digestion method was found irrelevant with other indicated methods. However, the ICP-OES measurements were found compatible with the dry ashing also with microwave digestion and suggested as a suitable method to determine boron contents of the maize shoots.  相似文献   

Assessing vulnerability of a forest ecosystem to climate change and variability in the western Mediterranean sub-region of Turkey     

Orkan zcan  Nebiye Musaoglu  Murat Türkes 《林业研究》2018,29(3):709-725

Climate change is a real, pressing and significant global problem. The concept of ‘climate change vulnerability’ helps us to better comprehend the cause/effect relationships behind climate change and its impact on human societies, socioeconomic sectors, and physiographical and ecological systems. In this study, multifactorial spatial modelling evaluated the vulnerability of a Mediterranean forest ecosystem to climate change and variability with regard to land degradation. This produced data and developed tools to support better decision-making and management. As a result, the geographical distribution of Environmental Vulnerability Areas(EVAs) of the forest ecosystem is the estimated Environmental Vulnerability Index(EVI) values. These revealed that, at current levels of environmental degradation, physical, geographical, policy enforcement, and socioeconomic conditions, the area with a ‘‘very low’’ degree of vulnerability covered mainly the town, its surrounding settlements and agricultural lands found principally over the low, flat travertine plateau and the plains to the east and southeast of the district. The spatial magnitude of the EVAs of the forest ecosystem under current environmental degradation was also determined. This revealed that the EVAs classed as ‘‘very low’’accounted for 21% of the area of the forest ecosystem,those classed as ‘‘low’’ for 36%, those classed as ‘‘medium’’ for 20%, and those classed as ‘‘high’’ for 24%.  相似文献   

Effect of boron application on calcium and boron concentrations in cell wall of durum (Triticum durum) and bread (Triticum aestivum) wheat     

Murat Ali Turan  Süleyman Taban  Günsu Barişik Kayin  Nilgün Taban 《Journal of plant nutrition》2018,41(11):1351-1357

A greenhouse experiment was conducted with three doses of boron (0, 1, and 10 mg B kg^?1 in the form of boric acid (H₃BO₃). Durum wheat (Triticum durum L. cv: Çakmak-79) and bread wheat (Triticum aestivum L. cv: Gerek-79) cultivars were used as plant material. B toxicity symptoms strongly appeared in durum wheat compared to bread wheat. Applications of B at 1.0 mg B kg^?1 stimulated and increased the dry weights of both the cultivars, while high level B application (i.e., 10 mg B kg^?1) depressed and decreased the dry weights significantly. B concentration and uptake in the leaf tip were increased with an increase in B application, whereas calcium (Ca) concentration and uptake were decreased in both the cultivars. It was observed that a substantial amount of B was accumulated in the plant cell wall. As similar to leaf tips, B concentrations in the cell wall also increased with B application, whereas Ca concentration was decreased.  相似文献
