Abstract: G ksu Delta is one of the most important nesting beaches in Turkey for the endangered loggerhead turtle (Caretta caretta). This paper provides information on the nesting activities of loggerhead turtles, the spatial and temporal distribution of nesting, nesting success, nesting density, hatching success, incubation duration and clutch size over two nesting seasons. A total of 902 emergences occurred over two seasons, of which 239 (26.5%) nests were deposited (137 nests in 2004 and 102 nests in 2008) and the overall mean nesting density was 3.4 nests/km. The peak of nesting emergences takes place mainly in June. Of the overall nests, 226 (94.6%) were excavated and 16044 eggs were counted. Of these eggs, 3680 (22.9%) hatchlings emerged and 2695 (73.2% of hatchlings) of them were able to reach the sea. The mean number of eggs per clutch was 71 (range: 15 – 143). The shortest and longest incubation duration in these 2 seasons ranged from 46 to 62 days with a mean of 53 days. The main problems are negatively affecting loggerhead turtle population at G ksu Delta are dense jackal predation both adult and eggs and inundation in nests. The average nesting effort here (mean: 119.5 nests/season) confirms that G ksu Delta is one of the most important nesting sites for loggerhead turtles in Turkey.
Excess molar volumes, and refractive index of binary mixtures of glycerol + methanol and glycerol + water at 298.15 K and 303.15 K

Abstract: Excess molar volumes (VE) viscosities and refractive index have been evaluated for binary mixtures of glycerol + water, and glycerol + methanol at 298.15 K and 303.15 K. Excess molar volumes (VE) have been calculated from density. The excess molar volume (VE) results were fitted to the Redlich and Kister type polynomial equation to derive the binary coefficients and estimate the standard deviations between experimental and calculated results. It is observed that all mixtures show positive values of VE obviously due to increased physical interactions between glycerol and methanol, and water.

Abstract: The study provides a crisp and comprehensive picture of the objectives with which the Indian organizations apply systems to appraise their employees,the basis the companies use to appraise their employees and the reasons for which the companies have attempted to adopt new systems of performance appraisal. Further the study works upon empirical data pertaining to the above system with special reference to Oil and Natural Gas Commission (ONGC), India. Also, certain suggestive schemes which this state statutory body has come up to overcome the limitations of the existing system and survive in the dynamic environment, have been mentioned.

Abstract: A total of 154 Japanese quail eggs which were stored throughout 0, 1, 4 and 7 days at 18°C and 60% RH from 10, 15 and 20 weeks of age were used to investigate relationships among different measures of thick albumen quality and Egg Weight (EW). Eggs were weighed and broken onto a glass surface and Albumen Height (AH), albumen pH, logarithm of AH, Haugh Unit (HU) and Internal Quality Unit (IQU) were determined. It was also determined that the correlation coefficients and linear regressions among the examined measurements. Both the decreases in AH, log of AH, HU and IQU or the increase in pH denote any deterioration in thick albumen characteristics by the age of hen and/or the storage duration. The regression coefficient of the albumen pH on age of the quail hen was merely found to be insignificant and rest of the albumen quality parameters were negatively affected by the hen age increased with low R2 values. On the other hand, all of the regression coefficients of the albumen quality parameters on storage duration were found to be significant. While the albumen pH increased by increasing storage duration, rest of the other quality parameters were decreased by the prolonged storage. The R2 values for storage duration were found to be relatively higher and more respectable than for hen age. There is no significant and/or fixed association among the examined measurements. Thus, it is not possible to develop any generalized (i.e., valid in all cases) formula which assumed any fixed association such in HU or IQU. In conclusion, albumen quality variables must be used without any adjustment especially for the appropriate comparisons among diverse groups of eggs.

Journal of Animal and Veterinary Advances , 2012, DOI: 10.3923/javaa.2012.2359.2366
Abstract: This research was carried out to investigate the impacts of different roof installations on heat-moisture balance and indoor thermal conditions of the poultry houses in cold seasons. Experiments were conducted in 3 different commercial type caged-poultry houses with the same capacity and characteristics but different roof insulations. Indoor and outdoor temperature and relative humidity values were measured for 5 months (October, November, December, January, February) to evaluate the effects of roof insulation on heat-moisture balances of the poultry houses. Results revealed the significance of insulation level of roof cover materials to keep the heat loss through structural elements at low levels. The heat loss from uninsulated roof (5.66 Wm-2 K) was almost 10 times higher than the heat loss from well-insulated roof (0.53 Wm-2 K).

Journal of Animal and Veterinary Advances , 2012, DOI: 10.3923/javaa.2011.3345.3349
Abstract: A total of 240 eggs from two commercial layer strains (ATAK and ATAK-S) at 30 and 40 weeks of ages were used to investigate relationships among measures of thick albumen quality and Egg Weight (EW). Eggs were weighed and broken onto non-reflective glass surface and Albumen Height (AH), Albumen Index (AI), Haugh Unit (HU) and Albumen Area (AA) were determined. The AA was calculated by digital image analysis. The correlation coefficients among AH, AA and EW and the linear regressions of EW on AH and AA were determined. Regression coefficients of the AH on the EW were insignificant and were ranged 0.02-0.059 mm g-1 showing that the fixed regression of 0.05 mm AH per gram of egg implied by the HU is wrong. The R2 values were ranged 0.4-4.5% and were fairly poor. The regression of the AA on the EW was significant but a bit higher than of the AH. The slope was always positive and was ranged 0.611-1.430 cm2 of AA g-1 of egg. The R2 values were ranged 7.5-21.1%. The EW was insufficient to determine both of AH and AA with a well fitted model. The fixed HU regression of AH or AA on EW is not adequate for diverse strain and age groups of eggs. The AH or AA alone will give a measure that is at least more accurate. However, image analysis to calculate irregular AA will provide an opportunity to easier and time-independent evaluation.

Abstract: Cerebral palsy is a general term which is used to describe a group of disorders that define muscle control impairment due to lesion in the developing brain. The aim of the present study was to indicate the common features of the children with cerebral palsy and their families in South Eastern region of Turkey, the most underdeveloped community in our country. In addition, the rate of marriage between the relatives (consanguineous marriage) is higher in this region than the other regions.A total of 258 children with a diagnosis of cerebral palsy were enrolled to our study. These children were born in South Eastern Anatolian region and live here throughout their childhood. Their families were also living in this region. The members of the families were interviewed with the questionnaire to obtain information. Statistical analysis of the results was performed with Graphpad Prism Ver 3.00.68.99 percent of the patients in our study were men, and 31.01 percent were women. They were between the ages of 10-375 months, average was 75.43±59.15 months. Rate of people, who was not under any social security guarantee, was 15.5%. 50.3% of mothers were not literate. Families’ income was 8.5% good, 42.6% poor. In families, there was 33.3% rate of relationship between partners (consanguineous marriage). In 15.5% of families, there was another retarded child. 55 percent of mothers were never been under health check in pregnancy period. Retarded child was usually from first delivery (26.3%). 3.1% of our patients had twin pregnancy. Only 59,6% of the whole births were given at the hospital or by the help of a midwife. Children were suckled along 6.4±6.4 months. Only 8,5% of the children were being educated.Finally, we concluded that reducing convertible risk factors caused by the low education level of our region, underdeveloped socioeconomic conditions and some traditions (e.g. consanguineous marriage and delivery in house instead of health organization) has potential importance in the meaning of reducing the number of children with cerebral palsy
