In this study, the heat transfer performance of a trunk pipe heat exchanger using motor oil as hot fluid and cold water as cold fluid was analyzed by a computational fluid dynamic (Ansys Fluent) program. The engine oil heat exchanger at different temperature ranges (70°C) and at different velocity (0.1m/s). Same case, the cold water at different temperature ranges of the heat exchanger (5°C) and different speed (1m/s) enters. The numerical results and mesh validations are shown below.

The study was conducted to determine the effects of sponge bath care on bilirubin levels of neonatals who underwent phototherapy with a diagnosis of hyperbilirubinemia. This experimental study was conducted in the neonatal intensive care unit of hospital in Eastern Turkey. Infants who met the selection criteria were included in the study without performing any sampling. A sponge bath was given to the infants in the experimental group (n=45) prior to phototherapy, and their bilirubin levels were evaluated. Except for routine clinical practices, no intervention was made for the infants in the control group (n=45). Ethical principles were applied in all phases of the study. In the study, no statistically significant difference was found between the groups, when the newborns in the experimental and control groups were compared in terms of gender, mode of delivery, gestational age, birth weight, and birth length or when they were compared in terms of Apgar score and physiological parameters (p>0.05). In the comparison of the bilirubin levels of neonatals included in the study, there was no difference between the experimental and control groups before the intervention; however, after the intervention, the difference between the groups was significant in favor of the experimental group (p<0.05). As a results the bilirubin levels were lower in experimental than control group. In the study, the sponge bath given prior to phototherapy was found to be effective in lowering the bilirubin levels. It is thought that this intervention can be used in neonatal care due to its positive effects. But more studies should be done to prove the decrease bilirubin levels of the sponge bath.

In this experimental study, we investigated the influence of the winglet, heat transfer, and pressure drop on the vortex flow to create a vortex in a stream of air sent to a fixed channel through a fan. Three parameters were determined as the winglets parameters: angle, height of the winglet, and arrangement in the channel of the winglet. The three winglet placed in the channel have the same angle and the same base height. Its experimental setup was applied for four different Reynolds numbers. The Nusselt number obtained from the smooth channel was compared with the correlations in the literature. Heat transfer results were obtained using thermal imaging technique. The heat transfer data obtained for all the specified test cases were compared with the smooth channel data. While comparing the Nusselt numbers and thermal camera images obtained from the experiments, the increases in heat transfer of the wing types have been examined and discussed.

Perceived insufficient milk causes mothers to feel that they are a failure in nutrition and breast-feeding, and they stop breast-feeding earlier. Early detection of these perceptions is important. The objective of this study is to adapt the Perception of Insufficient Milk Supply Questionnaire into Turkish mothers and conduct the validity and reliability analyses of the scale. The study was set in the neonatal unit of a university hospital in an eastern province of Turkey between June 2013-February 2014. Two hundred mothers, whose babies were hospitalized in neonatal unit, participated. The study included mothers who had no problem with breast-feeding, actively breastfed their infants, and clinically had a sufficient amount of milk. It was determined that mostly age group of mothers were 19-35 (91.5%); 39.5% were primary school graduates; a great majority of them (79.0%) were unemployed. The linguistic equivalence of the scale was primarily examined, and then its validity and reliability analyses were performed after confirming the linguistic equivalence. We conducted the language validity of the Perception of Insufficient Milk Questionnaire, which was adapted into Turkish. The following values were determined regarding the Turkish version of the Perception of Insufficient Milk Questionnaire: Test-content validity index 0.87, item total correlation scores 0.70 and 0.87, retest correlation value 0.81, and a Cronbach a coefficient of 0.82. According to these results, it could be asserted that Perception of Insufficient Milk Questionnaire is a valid and reliable assessment instrument for Turkish society.

In this research, The tulip (Tulipa armena) was collected from Mugla countryside, defined and content analysis was performed using LC-MS. Moreover, this research includes investigation of protein, phenolic component and some enzyme activities (protease and peroxidase). Three-phase partitioning method was used for purification of enzyme from flowers of Turkish tulip. The values of optimal pH and optimal temperature were determined for purified enzyme. The SDS-PAGE technique was used to check the purity of the purified enzyme and determine the number of subunits, if any. The molecular weight was also calculated using gel filtration chromatography. As a result, the protease enzyme was purified from Turkish Tulip flowers and its phenolic components were determined. It has been found that the purified protease enzyme has high activity. The plant extracts were prepared in different organic solvents and water. Furthermore, dilution grades of extracts were determined for animal experiments.
