Incidence and significance of incidental prostate carcinoma in transurethral resection (TUR-P) materials between 2014 and 2016 at our center. Like all organs, prostate has benign and malign diseases. Among benign diseases, benign prostatic hyperplasia (BPH) and among malignancies adenocarcinoma are the most common ones. One of the methods that is used to treat BPH is transurethral resection (TUR-P). In our study, we investigated incidental tumor rates observed in patients that have TUR-P due to BPH. We included 120 patients who underwent TUR-P and whose operation materials were examined in pathology department between 2014-2016 in our center. Benign diseases were noted in 117 (97.5%) of 120 patients, whereas malignant tumors were detected in 3 (2.5%) cases. In TUR-P operations performed to relieve symptoms in BPH, adenocarcinoma is reported in the literature at rates ranging from 4% to 15%. We suggest that patients with symptoms of prostatism should be carefully investigated, detailed histopathologic evaluation should be done in terms of incidental tumors and clinical pathology communication should be at maximum level.

This study examines that adsorption of Remazol Brillant Blue R (RBBR) from aquatic solution was studied using pistachio hull (PH) as an adsorbent. The removal efficiency of pistachio hull was studied as a function of, pH, initial dye concentration, adsorbent dose and time via batch method at room temperature. Langmuir and Freundlich Isotherms applied to obtained data from experiments. The correlation coefficient values shown that the data fit the Langmuir Isotherm (R 2 =0.9989) compare to Freundlich Isotherm (R 2 =0.7825). Maximum adsorption capacity was observed as 16.739mg/g. Thermodynamic parameters also studied. The value of Gibbs Free Energy, (ΔG=2.696kJ/mol) is positive. This value is indicated that the adsorption was not a spontaneous one. According to the experimental data, pistachio hull can be used as an appropriate, no cost and easy obtainable adsorbent for the removal of Remazol Brillant Blue R dye.
以开心果壳(PH)为吸附剂，研究了对水中瑞马唑(Remazol brilliant Blue R, RBBR)的吸附。在室温条件下，采用间歇法研究了pH、初始染料浓度、吸附剂剂量和时间对开心果壳去除率的影响。Langmuir和Freundlich等温线应用于从实验中获得的数据。相关系数值表明，数据符合Langmuir等温线(r2 =0.9989)，而Freundlich等温线(r2 =0.7825)。最大吸附量为16.739mg/g。热力学参数也进行了研究。吉布斯自由能(ΔG=2.696kJ/mol)为正。该值表明吸附不是自发的。实验结果表明，开心果壳可以作为一种合适的、无成本的、易获得的吸附剂来去除Remazol Brillant Blue R染料。

The temperature and dissolved oxygen parameters of Almus Dam Lake located in the district Almus of province Tokat were seasonally determined at nine stations located along the lake. The water quality class of Almus Dam Lake was determined by comparing the results of our measured parameters with the values of Intercontinental Water Sources Quality Classification. The spatial and seasonal variations in physical parameters were analyzed with the Two-Way ANOVA, the relationships among these parameters. According to Intercontinental Water Sources Quality Classification, Almus Dam Lake has Class I water quality when considering parameters of temperature (14.30±7.44C°), dissolved oxygen (10.15±2.67mg/L. With the examination of seasonal temperature-depth profile, it was observed that winter stagnation and spring and fall vertical mixing occurred during the January and March and spring May and November, respectively. Temperature stratification was clearly observed during the July and September. Epilimnion, metalimnion (thermocline) and hypolimnion were well clearly visible at the first 10 meters, between 10–20 meters, and below 20 meters, respectively . GIS maps with spatial and seasonal values were created for temperature and dissolved oxygen variables.
对位于托喀省阿尔穆斯区的阿尔穆斯大坝湖泊的温度和溶解氧参数进行了季节性测定。将测量参数的结果与洲际水源水质分类的值进行比较，确定了桤木坝湖的水质等级。采用双因素方差分析分析各物理参数的空间和季节变化。根据洲际水源水质分类，以温度(14.30±7.44C°)、溶解氧(10.15±2.67mg/L)为标准，Almus Dam Lake为一级水质。通过对季节温深剖面的分析，发现冬季停滞和春季和秋季垂直混合分别发生在1月和3月和春季5月和11月。7月和9月气温分层明显。在前10米、10 - 20米之间和20米以下，分别可以清楚地看到表层土、金属土(温跃层)和低表层土。为温度和溶解氧变量创建了具有空间和季节值的GIS地图。

Improvement of consumer consciousness and the increasing tendency towards consumption of natural products, and increasing resistance to antibiotics and antiparasitic medicines, have increasingly limited utilization of medicines for protection from diseases. It has also become impossible to use antibiotics and similar medicines for animals in order for preventive purposes except medical treatments as a result of recent legal arrangements and this situation caused new approaches for fighting with diseases. People have now focused on using as natural as possible products for treatment and prevention purposes. Immunostimulants are natural or synthetic components that are used at pets and poultries for various purposes, such as health, growth and performance increase, and they stimulate humoral and non-specific cellular immune system against pathogens. Studies showed that immunostimulants provide immunity against various disease factors, such as bacterial, viral and parasitic diseases, increase the survival rate and productivity, increase the effect of vaccines and antibiotics. They are preferred also because they are safer than chemotherapeutics. Taking necessary actions to protect hencoop from viral, bacterial and parasitic diseases and to prevent economic losses is important in poultry farming. It seems more suitable to use immunostimulants for prevention purposes before the disease occurs. However, since they have effectiveness increasing properties as adjuvants, it is also possible to state that they will be more effective for treatment if they can be used in combination. Therefore it is expected that therapeutically effective components can be developed in recent future with single or combined immunostimulant trials, which are not harmful to animals, humans and environment.

在本研究中，对三维土壤结构系统在动态载荷下的动态行为以及地表坑洼对隔振的影响进行了参数化研究。建模和分析采用了 Plaxis 3D 软件。坑的深度、宽度、长度和位置被选为研究参数。研究结果显示了地表的位移以及结构的位移和截面效应。研究结果表明，基坑深度是最有效的隔振参数。随着基坑深度的增加，地表和结构的振动会明显减小。另一个有效的隔振参数是基坑宽度。增加基坑宽度也会显著降低振幅。不过，这种减幅比深度的减幅要小。从所得结果可以得出结论，基坑的长度、位置和不同材料的填充对隔振影响不大。

Accepted as a global health problem, obesity is described as the amount of fat in the body exceeding ideal limits. Because obesity is seen as a risk-taker in the formation of chronic diseases, obesity may cause patients and healthcare professionals several difficulties in diagnosis, treatment and care processes by increasing the admission of patients to hospitals. This difficulties in obese patient care develops on physical environment, lack of suitable equipment and staff, and surgical process and cause inability to provide patient and nurse safety and decrease of nurses’ satisfaction of giving care. The use of special devices designed for obese patients in the services ensures the safety of both the patient and healthcare professionals. The availability of these devices at the services alone is not enough, but it is also necessary for health workers to receive special training on how to use these devices and give obese patient care.

Katkisiz PA 6 ve PA 6 karisimlarinin asinma ve surtunme davranislari pim-disk asinma cihazinda ve kuru kayma sartlari altinda gerceklestirilmistir. Katkisiz PA 6 ve PA 6/PTFE karisimlarinin asinma ve surtunme davranislari 0.5m/s kayma hizinda ve 10N, 20N ve 30N yukler altinda yapilmistir. Calisma sonucunda, PA 6 polimerine ilave edilen PTFE katki, polimer karisiminin hem surtunme katsayisi hem de spesifik asinma hizi degerlerinin azalmasina sebep olmustur. Uygulanan yukun artmasi ile surtunme katsayisi degerleri azalirken spesifik asinma hizi degerleri de artmistir.
在这项研究中，首先研究了未掺杂聚酰胺 6 的聚酰胺 6 聚合物混合物和含有 5% 和 10% 聚四氟乙烯（PTFE）添加剂的聚酰胺 6 聚合物混合物的磨损和摩擦性能。这些聚合物混合物是在一台工业双螺杆混炼机上以颗粒状生产的。实验中使用的试样是用传统注塑机印制的。未掺杂的 PA 6 和 PA 6 混合物的摩擦和磨损行为是在针盘摩擦装置和干燥滑动条件下进行的。在 0.5m/s 的滑动速度和 10N、20N 和 30N 的载荷下，对 PA 6 和 PA 6/PTFE 混合物（不含添加剂）的磨损和摩擦行为进行了研究。研究结果表明，在 PA 6 聚合物中添加 PTFE 添加剂会导致聚合物混合物的摩擦系数和摩擦比速下降。随着施加载荷的增加，摩擦系数值降低，比摩擦速度值增加。
