Water has a complex relationship with agricultural activities, economy, health, use of energy resources and hygiene. In parallel with climate change and population growth, the inadequacy of our water resources in the coming years is one of the major problems we are likely to face. Estimating how much of the available water can be used and how much the water potential will change in the future can enable more accurate water planning. The average flow, total precipitation and average temperature values of Tagar Stream Küçükkumluk and Porsuk Stream Porsuk Çiftliği Station were analyzed together and the river flow rate was estimated. Linear Regression, Support Vector, Decision Trees, Random Forest and Extra Trees methods were applied for flow estimation. In order to improve the performance of each of the applied models, a hybrid method was developed using Wavelet Transform. Approximately 65% of the dataset is divided into training, 15% validation and 20% test data. ETR was found to be the most successful prediction method with 70.8% for Tagar Stream Küçükkumluk and 67.67% for Porsuk Stream Porsuk Farm. The developed hybrid model increased the success rate for all methods; the highest increase was obtained in SVR method with 20.82% for Küçükkumluk and 30.64% for Porsuk Farm. The most successful method was obtained in the ETR method with 91.46% and 86.39%. [ABSTRACT FROM AUTHOR]

Bu çalışmada, perlit (PT) ve uçucu kül (UK) bazlı geopolimerlere çömlek sırı atığı (ÇSA) ikamesinin mekanik özellikler ve yüksek sıcaklık performansı üzerindeki etkisi araştırılmıştır. Sadece PT, sadece UK ve ağırlıkça %75 UK ve %25 PT içeriği ile üretilen geopolimer harçlara %10, 20 ve 30 oranlarında ÇSA ikame edilmiştir. Harçlar, sabit 10M NaOH içeriği ve 8 saat 100 ºC ısıl kür ile üretilmiştir. Üretilen harçların 7, 28 ve 90 günlük eğilme ve basınç dayanımları belirlenmiş ve 500 ºC, 750 ºC ve 1000 ºC sıcaklıklarındaki performansları değerlendirilmiştir. Deneyler sonucunda, ÇSA malzemesinin PT ve UK+PT içeren numunelere kütlece %20 oranına kadar ikame edilmesinin nihai basınç dayanımı açısından olumlu yönde etkileri olduğu, UK içeren numunelerde ise ÇSA ikamesinin nihai basınç dayanımı açısından olumsuz etkileri olduğu tespit edilmiştir. Nihai dayanımlarda en yüksek değerler, 34.4 ve 32.41 MPa basınç ve 6.46 ve 6.3 MPa eğilme dayanımları ile UK+PT+ÇSA içeren numunelerde sırasıyla %10 ve 20 ÇSA oranlarında elde edilmiştir. Eğilme ve basınç dayanımları açısından optimum ÇSA oranının %10-20 aralığında olduğu söylenebilir. UK malzemesine ÇSA malzemesinin ikamesi, kür yaşına göre dayanım gelişimlerini olumsuz etkilerken, PT ve UK+PT içeren numunelere ÇSA malzemesi ikamesi dayanım gelişimlerinde olumlu etkiler meydana getirmiştir. ÇSA malzemesi yüksek sıcaklık performansı açısından tüm gruplarda olumlu etki meydana getirmiştir. ÇSA malzemesinin karışımlarda kütlece ikame yüzdesi arttıkça, dayanım kayıpları azalmıştır. UK malzemesinin yerine %30 ÇSA malzemesinin ikame edildiği numunelerde 750 ºC’de %40’a varan dayanım artışı tespit edilmiştir.

Due to the excessive temperature rise in the Central Processing Unit (CPU), computers shut down and system damage occurs over time. In this study, a new thermoelectric cooling system is designed to reduce the temperature in the CPU. The novel cooling system is designed using a thermoelectric module. It is to remove the excess heat by conduction and convection by taking advantage of the temperature difference between the thermoelectric cooler and the CPU we add to the system. Since the temperature of the thermoelectric cooler will always be lower than the CPU temperature, effective cooling will be provided. A special electronic circuit and software have been developed for the control of the cooling unit. Three different artificial intelligence models (artificial neural network, random forest, and k-nearest neighbor) were created to dynamically control the additional cooling system and their successes were compared. Artificial intelligence determines the power and fan speed of the thermoelectric cooling system. It performs this control by evaluating all parameters (different values such as CPU frequency, voltage, number of processes) instead of a specific CPU load or a specific temperature value. While the CPU temperature was 41°C at maximum load, this temperature was reduced to 31°C thanks to the designed thermoelectric cooling system. All methods provided a high classification success in education. By using the artificial neural network 97.973% classification success was achieved, whereas the classification success for random forest and k-nearest neighbour model were 97.297% and 96.306%, respectively.

Rock strength is an important parameter in mining project processes. The distribution of strength values is important in rocks showing different strength properties according to orientations in terms of strength anisotropy, such as sedimentary and metamorphic rocks. The studies can be carried out at different temperatures and pHs. Strength values may change in summer, winter, acidic and basic conditions. In this study, schist samples were taken from the copper mine in the Hanönü district of Kastamonu, Türkiye. Besides the strength anisotropy of metamorphic rocks such as green schist and mica schist, the variation of strength values at different temperatures (5°C and 35°C) and pH (2, 7 and 12) was investigated. In general, minimum strengths at 15°-45° and maximum results between 60°-90° degrees were obtained for both rocks. Generally, both rocks showed maximum strength distribution at 5°C. Maximum strength was obtained at pH12 for mica schist, close distribution at other pH values, and similar distribution at all pH values for green schist. The degree, temperature, and pH parameters affected the strength of mica schist, while the degree and temperature parameters were effective in the strength of green schist. Examination of the effect of the change of different parameters on the strength of the rocks will contribute to the project and operation processes. [ABSTRACT FROM AUTHOR]

In microbiological characterisation, experimental conditions emerge as a significant parameter affecting the result. In this study, the tolerance of 50 yeast isolates to bile salts was investigated under three different temperature conditions (26°C, 30°C, and 37°C) and two different media (Sabouraud2% dextrose broth and Yeast Peptone Dextrose Broth, YPD). In general, similar growth was observed in both media at 26°C and 30°C. However, at 37°C, it was determined that four, three, and three strains developed in SDB medium with 0.3%, 0.5%, and 1% bile salt, respectively, while nine strains developed in YPD medium. When YPD and SDB media were compared in terms of yeast growth, it was observed that YPD supported the growth of a greater number of strains at different temperatures and bile ratios. The study determined that Kazachstania unispora was the species most affected by the experimental conditions. [ABSTRACT FROM AUTHOR]

In the study carried out in 8 villages and 27 cotton parcels of Mardin Province Artuklu and Kızıltepe Districts, ambient humidity and temperature values in the field were measured and recorded with data logger devices at 6-hour intervals. The data obtained from the data loggers were analyzed with the Sentinel-1 and Landsat-8 satellite data prepared in the Google Earth Engine (GEE) environment and the relationship between them was examined. While a high correlation was found between ambient humidity (ON) values and VV (R²=0.63), VV-VH (R²=0.68), Soil Moisture Index (SMI) (R²=0.84), low correlation was found between VV (R²=0.51), VH (R²=0.06), VV-VH (R²=0.49), LEE_VH (R²=0.09), LEE_VV (R²=0.49), GAMMA_VH (R²=0.11, GAMMA_VV (R²=0.08), MALIK_VH (R²=0.08), MALIK_VV (R²=0.49), SMI (R²=0.50). A high correlation was found between ambient temperature (OS) values and Land Surface Temperature (LST) (R²=0.80**). However, a low correlation was found between ambient temperature (OS) and VV (R²=0.51), VH (R²=0.06), VV-VH (R²=0.49), LEE_VH (R²=0.09), LEE_VV (R²=0.49), GAMMA_VH (R²=0.11, GAMMA_VV (R²=0.08), MALIK_VH (R²=0.08), MALIK_VV (R²=0.49), SMI (R²=0.50). In large-scale field studies; VV, VV-VH and SMI index in estimating ambient humidity values; as it was concluded that the LST band can be used with high accuracy in estimating ambient temperature values, it has been recommended.

Objective: Low air temperature has been shown to predispose testicular torsion (TT). In this study, we aimed to examine the relationship of TT occurrence with monthly average temperature. Materials and Methods: The files of 75 male patients who were admitted with acute scrotum between 2005 and 2021 and underwent intervention with a preliminary diagnosis of TT after examination were retrospectively analyzed. The mean age, date of admission, torsion side and interventions were recorded. All patients underwent scrotal doppler ultrasonography. Further, monthly average temperature values of the given years for the province were obtained from the General Directorate of Meteorology. Months were ranked in descending order in terms of average monthly temperature and divided into two groups as warmer and colder months. Results: The mean age of the patients at the time of intervention was 17.02±0.78 years. TT was seen on the right side in 49(67.1%) patients, left side in 23(31.5%) and bilateral in 1(1.4%) patient. Two (2.6%) patients turned out not to have TT and were excluded from the study. The warm months were those from April to September, and the cold months from October to March. It was determined that testicular torsion developed in 41 (56.2%) patients in the warm months and in 32 (43.8%) patients in the cold months. Detorsion and fixation were performed in 50(68.5%) of the patients, orchiectomy in18 (24.6%) and manual detorsion preceded by fixation in another session in 5 (6.9%) patients. Conclusion: Our results indicated that TT may be observed more frequently in warm months. Thus, TT might not be related to seasonal temperature changes. [ABSTRACT FROM AUTHOR]

In recent years, it has gained importance to develop models to determine the contribution of parks to reducing the temperature together with their surroundings. ENVI-met, which is used for this purpose, allows simulations for different conditions/materials with projections over many years. This study aims to determine the temperature levels arising from the surface materials and the projections of long years in the near areas of Cumhuriyet Park in Çukurova District of Adana. The study consists of 3 stages. In the first stage, information about the subject was gathered together. In the second stage, modeling was carried out using ENVI-Met 4.4.5 climatic simulation software in order to determine the temperature levels caused by different materials in the study area. The scenario for the future has been put forward. The data obtained in the third stage of the study were evaluated and suggestions were presented. As a result of the study, it was determined that Cumhuriyet Park, which is one of the important green areas of Çukurova district, contributed significantly to the decrease in the temperature level around it. This contribution is felt more intensely especially in the immediate vicinity of the park. It has been shown that the effect decreases with distance from the park. In the scenario put forward at the end of the 28-year period, it is predicted that the temperature level of the parking area will increase by approximately 2.4°C. This study reveals the importance of the selection of soil materials in preventing the warming of cities because of climate change experienced all over the world. In this context, local administrations attach importance to efforts to increase the quality of urban life; developing strategies in this regard is important for achieving results.

In this study, it was aimed to optimize the ultrasonic rehydration conditions of dried tomatoes. Rehydration conditions were optimized by Response Surface Method (RSM). The optimization of ultrasonic (37 kHz) rehydration conditions were performed with independent variables at different temperatures (20-80°C), time (2-60 min) and water ratios (1/50-1/100 g/g water), and rehydration ability, color a* (redness) and texture values were selected as responses (dependent variable). The estimated and experimental analysis results were compared in the selection of the optimum rehydration condition. As a result, it was determined that ultrasonic rehydration at 58°C/54 min/72 ml water conditions could be used as the optimum point. At the selected optimum point, the rehydration ability, color a* value and texture values were determined as 2.82±0.16, 13.09 ±1.63 and 0.46±0.13 N, respectively. These results are seen as proof that ultrasound application can be used in the rehydration of dried tomatoes.

Highway networks are the most widely used transportation network in Turkey. It is very important to determine the maintenance and repair needs correctly and to apply appropriate methods at the right time in order to manage the large resources used in road construction and to reduce the expenditures to the optimum level. The current structural and functional condition of the pavement should be determined in the maintenance - repair planning. The existing structural and functional condition can be determined by methods such as laboratory studies and research pit, or it can be determined using non-destructive testing methods. The structural condition of the road pavement can be determined non-destructively with Falling Weight Deflectometers (FWD). In FWD measurements on flexible pavements, the measurement results of Hot Mixture Asphalt (HMA) layers vary by temperature. In this study, the effect of asphalt temperature on deflection measurements of flexible pavements was investigated. [ABSTRACT FROM AUTHOR]

The occurrence of Armillaria mellea (Vahl) P. Kumm. and the ecological characteristics of this fungus were studied in Kocaeli, Yuvacik dam basin mixed-broad leaved forests. During the surveys, we analyzed the sporocarps (fruiting bodies) of A. mellea growing up on woody plants in plots selected by cluster sampling in the Yuvacik dam watershed dominated by broad-leaved forests. The Runs test results showed that randomness rules complied in the selection of the plots, and there was no tendency (p= 0.109 > 0.05, z= -1.603). The presence/absence of A. mellea and environmental variables were tested with Chi-square analysis, and the temperature differed among these environmental variables. To the dendrogram, A. mellea was mainly seen in the south of the study area and preferred western aspects. It is understood that this macrofungus prefers the south of the study area because of the altitude. Our data showed that sporocarps of A. mellea generally occurred in the western aspect, at temperatures of 15-20°C, >80% humidity and 800-1000 m altitude. Our logistic regression analysis model (z=-9.508+0.307×temperature+0.081×humidity) showed that if the temperature and humidity change by 1 unit in the region, sporocarp formation is affected by 36% and 8.4%, respectively.

Infrared thermographic imaging of horses is becoming more popular in equine practice, and it is regarded to be a valuable method for detecting lesions with the potential to cause lameness. The current study aimed to investigate the effectiveness of thermal camera in determine the location of lesions in horses with lameness. Twenty four Arabian horses aged 6.3±1.8 (mean±standard deviation) years old were included in this study. Temperature measurements were obtained with a thermal camera on the fore and hindlimb of all horses with lameness and the area where the temperature increased (suspected area) was detected. Following the suspected area was determined, temperature measurements were performed in the symmetric area of the same animal. All thermal camera temperatures were taken from four different points (lateral, medial, dorsal, palmar/plantar) and the average of measurements was recorded. The mean temperature measurement in the suspected area (34.7±1.7 °C) was significantly higher than the symmetric area (31.8±2.1 °C) in horses (p<0.001). In conclusion, thermography can be used to determine rapidly and effectively the localization of the orthopedic lesion in horses. [ABSTRACT FROM AUTHOR]

In this study, it was aimed to reveal the effect of temperature and humidity values provided by the semi-open and closed barns in the winter season on milk yield and components and the somatic cell count (SCC) level in milk in Anatolian buffaloes, and for this purpose, to compare both barn types and to reveal their suitability for buffalo breeding. In the study, temperature and humidity values were determined between December 2020 and March 2021 in two types of barns with similar feeding conditions in Bafra district, Samsun, and milk samples taken from buffaloes raised in these barns were analyzed. Temperature Humidity Index (THI) values were determined as 61,09±0,211 and 51.08±0.173 for the closed and semi-open barn type, respectively. In the study, in which the type of barn and therefore the temperature and humidity values provided in the barn environment did not affect the amount of milk yield, the milk fat ratio was determined as 8.89±0.227% and 8.16±0.176% for closed and semi-open barns, respectively. While other milk components were not affected by the barn conditions, the logSCC of milk was lower (4.54±0.071) in the closed barns when compared to the semi-open barns (4.73±0.044). Although no statistical difference was determined in the other milk parameters discussed, it was noted that there is an increasing tendency in the closed barns. It was observed that the changes in temperature and humidity values in both barn environments during the period caused nonlinear changes in milk composition. While indoor conditions were more effective on solids-non-fat (SNF), protein and lactose in the closed barn, the highest effect was on the fat ratio and logSCC in the semi-open barns. As a result, it can be said that both types of barns can be used in buffalo breeding since there is no significant difference in milk yield and other components, although there is a slight difference in milk fat ratio and logSCC level in closed and semi-open barns of Anatolian buffaloes in the climatic conditions of the region where the study was conducted.

White mustard (Sinapis alba L.) is one of the two important species in Turkey in the Sinapis genus belonging to the Brassicaceae family. It is a weed found in agricultural areas in weed surveys conducted in our country in recent years. This study was carried out with the seeds of White mustard (S. alba L.) randomly collected from the fields of Manisa province in 2019, and the minimum, optimum and maximum germination temperatures of the seeds of this weed species were determined. The experiment was carried out in Malatya Turgut Özal University, Faculty of Agriculture, Department of Plant Protection, Herbology laboratory in 2022. In laboratory studies, temperatures of 2, 5. 10, 15, 20, 25, 30, 35 and 40 °C were used to determine the appropriate germination temperatures of White mustard seeds. Experiments were set up with 4 replications and repeated 2 times. As a result of the study, it was determined that the minimum, optimum and maximum germination temperatures of White mustard seeds were 5 °C, 20-25 °C and 35 °C, respectively. Since the results were parallel to each other, the average of the two trials was taken into consideration. As a result, due to global warming, White mustard weed species cause problems in cultivated plants and can increase population density in important cultivated plants if they are not controlled. Seed biology is important in the control of the White mustard species, and the findings revealed the germination abilities of the White mustard species at appropriate temperatures. In addition, it is thought that this study will shed light on other studies to be done with White mustard in the coming years. [ABSTRACT FROM AUTHOR]

Drosophila suzukii Matsumura 1931 (Diptera: Drosophilidae) is an important quarantine pest that damages soft tissue fruits. Determining the biological characteristics of the pest is the main element of effective control with the pest, which has the ability to spread rapidly. Therefore, in the study discussed in 2019, the development of D. suzukii was determined by six constant (10, 15, 20, 25, 30 and 35±1 °C), two variable (15/25 and 25/35±1 °C) temperatures., 65±10% relative humidity and 16:8 (Light: Dark) lighting conditions were determined in air-conditioning rooms. At the same time, the study of determining the preferred fruit maturity period of D. suzukii was carried out at a constant temperature (25±1 °C) in a climate cabinet with 65±10% relative humidity and 16:8 (Light: Dark) lighting conditions. As a result of the study, D. suzukii from egg to adult at 33-38 days at 10 °C, 18-23 days at 15 °C, 12-14 days at 20 °C, 8-9 days at 25 °C and 13-20 days at 15/25 °C has become. However, no development was observed in their biological stages at 30, 35 and 25/35 °C. On the other hand, in order to determine the maturity period in which D. suzukii prefers the fruit, the experiment was established with and without preference in different phenological periods of the cherry fruit such as green / yellow / red / dark red. In the preferential set-up trial, 60% of the red fruit stage and 90% of the dark red fruit stage were found to be rough, and in the non-preferential set-up trial, 60% of the red fruit stage and 80% of the dark red fruit stage were determined. In addition, no damage was observed in the green and yellow periods in both experiments. As a result, in the development of D. suzukii, temperature is important factor and it has been determined that the fruit is preferred in the red period and the dark red period.

İklim değişikliği sonucu yaşanan ekstrem hava olayları, küresel ısınma, kuraklıklar, seller vb. birçok durum ülkemizin karşı karşıya kaldığı en önemli sorunlardan biridir. Ortalama sıcaklıklardaki ve yağışlardaki artma/azalma eğilimleri, bu konuda hazırlanan/hazırlanacak çalışmaların önemini ortaya koymaktadır. Bu çalışmada Türkiye’nin Güneydoğu Anadolu Bölgesinde, makro iklim sahası itibariyle Akdeniz iklim bölgesinde yer alan Şanlıurfa ilinin yağış ve sıcaklık eğilimleri analiz edilmiştir. 1965-2019 yılları arasında ölçümlerinin yapıldığı yağış-sıcaklık verileri Mann-Kendall ve Sen Slope yöntemiyle yıllık ve mevsimlik olarak analiz edilmiştir. Elde edilen bulgular araştırma sahasındaki Akçakale ve Ceylanpınar istasyonlarının yağış eğilimlerinde anlamlı azalmaların yaşandığını (Azalmaların anlamlılık düzeyi: Akçakale’de 0.05; Ceylanpınar’da 0.01’dir); Şanlıurfa merkez ve Birecik istasyonlarında ise anlamlı olmayan azalmaların yaşandığını; Siverek istasyonunda ise anlamlı olmayan artışların yaşandığını ortaya koymaktadır. Sıcaklık eğilimlerinde ise araştırma sahasındaki tüm istasyonların 0.001 anlamlılık düzeyinde artışların yaşandığını göstermektir. Özellikle araştırma sahasında son yıllarda azalan yağış eğilimine karşın artan sıcaklık eğilimi dikkat çekicidir.

A comprehensive study has been carried out for Turkey to investigate temperature variabilities and trends in a 50-year period of 1969-2018. Daily temperature data belonging to 174 meteorological stations which was collected from Turkish Meteorological State Service was used in this research. Temporal and spatial variability of temperature have been studied by linear regression, 3-yr moving average and non-parametric Mann-Kendall test. Yearly and seasonally average temperature of each region has been formed from analysis of daily average temperature for this time period. Temperature increase in this recent half century time period is found to be in the Eastern Anatolia Region with a value of 1.74°C/50 years. The regions with the highest seasonal temperature increases are estimated to be the Aegean Region (1.61°C) in autumn, Eastern Anatolia Region (2.37°C) in winter, Eastern Anatolia Region (1.84°C) in spring and Marmara Region in summer (2.79°C). Moreover, yearly temperature trends showed increasing trends at 99% confidence interval in most stations. Increasing trends at 99% confidence interval have been confirmed in most regions from analyzing seasonally and yearly temperature trends.

Two-dimensional (2D) carbon-based nanomaterials have received significant attention because of their high physical properties, in recent years. In this investigation, the mechanical properties of graphene-like C4N3 structure are studied in detail, using molecular dynamics (MD) simulations. According to the results of MD simulations, this structure shows superior mechanical properties (ultimate tensile strength, Young's modulus and failure strain). The mechanical properties of graphene-like C4N3 structure are also examined at five distinct temperatures between 200 K and 900 K along the different loading directions and various strain rates from 107 s-1 to 109 s-1. MD results show that the mechanical properties of this structure gradually decrease as temperature increases, due to the weakening effect of high temperature on the binding energy between atoms. Furthermore, as the strain rate increases, it is revealed that the mechanical properties show an increasing trend. The mechanical properties of this structure are isotropic as a result of loading in the armchair and zigzag directions. Additionally, at 300 K, the failure process of graphene-like C4N3 structure is examined. MD simulation results demonstrate that this structure has brittle failure mechanism. The results of this study may be considered helpful for future works of mechanical management of 2D carbon-based nanodevices. [ABSTRACT FROM AUTHOR]

The aim of this study is to reveal the temperature and precipitation trends for 9 meteorological stations in Sivas. Temperature and precipitation data (Sivas Center (1929-2019), Kangal (1959-2019), Suşehri (1970-2019), Zara (1964-2019), Divriği (1959-2019), Gemerek (1963-2019), Gürün (1964-2019), Şarkışla (1963-2019) and Ulaş (1957-2019)) of these meteorology stations in different observation year intervals were obtained from Sivas Meteorology Directorate. With the help of Mann-Kendall trend test, trend analysis was performed for spring, summer, autumn, winter and annual period. It was determined that the annual average temperature values showed a statistically significant increase trend at all stations except Gürün and Ulaş districts. In terms of annual average precipitation values, a statistically significant decrease trend was observed in Kangal, Şarkışla and Ulaş districts. Temperature values for Sivas Central station increased by 2 oC on average, while precipitation values decreased by 10 mm. Temperatures have increased throughout the study area, and precipitation values have decreased in Şarkışla and Ulaş districts. This study revealed that changes in temperature and precipitation trends support the phenomenon of climate change in the study area. The results of the study are expected to help climate-related risks and water resources management. [ABSTRACT FROM AUTHOR]

In order to explore the most suitable temperature for the preservation of Hu ram semen at room temperature, the semen samples were placed at 15°C, 20°C, and 25°C respectively. Th e energy metabolism of enzyme activity and triphosphate adenosine (ATP) was detected in the process of preservation. Diff erent parameters such as functional integrity, survival time, reactive oxygen species (ROS) content, superoxide dismutase (SOD) activity, and energy metabolism of adenosine triphosphate (ATP) were detected. Th e results showed that within 2 days of storage, the sperm progressive motility stored at 25°C was the highest. Within 3~5 days of storage, sperm stored at 20°C have the highest progressive motility. Within 6~9 days of storage, the sperm progressive motility stored at 15°C was signifi cantly higher than that of the other groups (P<0.05). Th e eff ective survival time and total survival time of sperm stored at 15°C reached 5.67 d and 18.73 d, respectively, which were signifi cantly higher than those of other groups (P<0.05). On the 1st day of storage, the sperm membrane integrity was signifi cantly higher than that of the other groups (P<0.05). Within 3~5 days of storage, the membrane integrity and acrosome integrity of sperm stored at 15°C and 20°C were signifi cantly higher than the sperm membrane integrity and acrosome integrity stored at 25°C (P<0.05). On the 7th day of storage, the membrane integrity of sperm stored at 15°C was signifi cantly higher than that of other groups (P<0.05). On the 5th day of storage, the level of sperm ROS stored at 15°C was signifi cantly lower than that of group 25°C (P<0.05), SOD activity, Catalase enzyme (CAT) activity and ATP content were significantly higher than that of the other groups (P<0.05). Th erefore, compared with 20°C and 25°C, 15ºC was the most suitable temperature for the preservation of Hu ram semen at room temperature. [ABSTRACT FROM AUTHOR]

Shalgam has been a fermented beverage produced in high amounts and consumed widely in Turkey in recent years. Despite its potential, there is no specific processing method or temperature for the production of shalgam beverages. Therefore, in this study, some changes in shalgam obtained by using two production processes (conventional and rapid processes) at 25 and 35°C were monitored during 4 months of storage. In particular, changes in color values that might affect product quality and attractiveness were influenced by production method, temperature and storage time. The highest a* and b* color values were found in samples produced by using the rapid process at 25°C (5.61 and 0.12, respectively) while the lowest values were found in those manufactured by the conventional method at 35°C. The L* values of beverages changed by storage time. In addition, while the content of anthocyanins decreased by storage time, the content of total antioxidants increased. Additionally, when production temperatures were compared, total aerobic mesophilic bacteria counts in shalgam beverages were higher at 35°C than 25°C. All samples produced at two different temperatures and with two different methods showed a decrease in the number of lactic acid bacteria at the end of storage time. Considering all the changes, it could be concluded that it would be inappropriate to store shalgam beverages at room temperature for 4 months or longer without using any heat treatment or preservative.

Polymer hybrid ball bearings' balls and rings consist of different materials. Rings have been manufactured viskoelastic material. The traditional ball bearings ball-ring contact analyse with Hertzian contact theory but polymer hybrid ball bearings has not been analyse with the Hertzian contact theory. Polymer ring-ball contact has been analysed with elasto-plastic contact model instead of Hertzian contact theory. Elasto-plastic contact model has two model which are indentation and flattening. These model have been evaluated contact area as elastic region, elasto-plastic region or plastic region. Elastic contact region evaluate the same as Hertzian contact theory. Ball bearings has long lifetime to run elastic region and away from resonance condition. Friction has been caused the systems temperature to rise while the shaft-bearing system run. This condition has been caused to drop elastic modulus and stiffness of polymer bearing. Elastic modulus has been affect the bearings force capacity and stiffness. Stiffness affect the natural frequency of systems. For researching temperature effect on elastic modulus and vibration characteristic of ball bearings mathematical model has been created. Radial deep groove ball bearings geometric and material properties have been used in mathematical model. Simulations have been done via MATLAB software program. As a result, elastic modulus and natural frequency of systems' decreases with temperature rise. Although force capacity related with elastic modulus, force capacity increase with temperature rise because of critic deformation. [ABSTRACT FROM AUTHOR]
