Bu araştırma Artvin Orman Bölge Müdürlüğü, Artvin Orman İşletme Müdürlüğü, Merkez İşletme Şefliği sınırları içerisindeki Genya Dağı bölgesinde yayılış gösteren saf Doğu Ladini meşcerelerinde bonitet endeksi ile bazı edafik ve fizyografik özellikler arasındaki ilişkilerin saptanabilmesi amacıyla gerçekleştirilmiştir. Bu amaçla Genya Dağı bölgesinde saf olarak yayılış gösteren Doğu Ladini meşcerelerinden 50 tane deneme alanı seçilmiş, her bir deneme alanına ilişkin fizyografik ve edafik özellikler belirlenmiştir. Toprağa ilişkin özelliklerin belirlenebilmesi için toprak profilleri açılmış ve örnekler alınmıştır. Ayrıca her bir deneme alanında meşcerelerin bonitet endeksi (100 yaşındaki üst boy) belirlenmiştir. Meşcere bonitet endeksi ile edafik ve fizyografik faktörler arasındaki ilişkiler korelasyon analizi ile sorgulanmıştır. Bu ekolojik etmenlerden eğim, fizyolojik toprak derinliği, mutlak toprak derinliği, Ah ve B horizonundaki kil ve kum miktarıları (%) ile bonitet endeksi arasında önemli ve anlamlı ilişkiler bulunmuşturThe aim of this study is to explain relationships between site index and some edaphic and physiographic factors of pure oriental spruce (Picea orientalis Link.) in Genya mountain located in central Management district in Artvin State Forest Enterprise. In order to do this study, the fifty sample plots were selected from oriental pure spruce stands in Genya Mountain. Edaphic and physiographic factors in each sample plots were determined. The soil profiles were digged to determine some attributes relating to soil. Also site index of each plots were determined using average height of dominant and co-dominant trees at reference age at 100. The relationships between site index and edaphic and physiographic factors were investigated using correlation analysis Among these ecological factors; slope, physical soil depth, absolute soil depth, the amount of silt and clay in Ah and B Stratus shows significant relations with site index

As a result, among the general energy inputs in apple cultivation, the highest energy consuming items have been respectively defined as fertilizer energy, fuel-oil energy, chemicals, machinery, human labour and irrigation energy

Effect of Mitomycin C in the prevention of tendon adhesion after surgery and the effect of biomechanical stretching on tendon histology

Objective: In this study, optimal dose to reduce tendon adhesion, by using the dose-dependent fibroblast proliferation inhibition effect of Mit-C, and the level, which the tendon histologies are affected, using biomechanical stretching, is investigated. Methods: 56 chicken flexor tendons were used in this study. A total of 9 groups were formed. Mit-C were applied between the tendon and the sheath; 0.9% NaCl for surgical control groups (groupII, groupIII), 0.1mg/ml Mit-C (groupIV, groupVII), 0.2mg/ml Mit-C (groupV, groupVIII) 0.5 mg/ml Mit-C (groupVI, groupIX). Macroscopic, microscopic, synovial sheath thickness and active fibroblast count were compared between the groups that underwent biomechanical stretching (groups III,V,VII,IX) and groups without biomechanical stretching (groups I,II,IV,VI,VIII). Results: After the macroscopic and microscopic examination, it was observed that the groups with the most adhesion were surgical control groups. The best results from the experimental groups were seen in group VIII, but the results of the groups were similar. When active fibroblast count was examined, it was seen that group VIII had the least active fibroblast count. Conclusion: According to the results of the evaluation, Mit-C, by inhibiting fibroblast proliferation and decreasing synovial sheath thickness, decreased adhesion formation. At the same time, it was concluded that the optimal dose for adhesion prevention was 0.2mg/ml, biomechanical stretching affected tendon histology and the drug was suitable for clinical studies

Identification of resistance to Eurygaster integriceps Put. on some bread wheat genotypes

Sunn pest (Eurygaster integriceps Put.) is one of the most important pests of wheat in Eastern Europe including Turkey, West and Cen-tral Asia. Its damage on leaves, stems, spikes and grains reduce the baking quality of flour made from damaged grains. In this study, some wheat genotypes from Turkey and ICARDA were evaluated for the pest resistance. The genotypes were planted in a randomized block design using hill plots in nylon mesh screening cages in wheat growing season of 2011-2012 and 2012-2013. Sunn pest population was collected from Çanakkale province, where the pest was intensely found in recent years. The plants of each hill plots were infested with one male and one female Sunn pest adults. The results with 12.5% sucking damage showed that the genotypes from ICARDA had higher resistance than the landraces from Turkey to Sunn pest. Especially, the genotypes IC3 and IC4 from ICARDA and TR7 from Turkey with respect to their SED and DSED values were found the most promising genotypes resistant to Sunn pest for future breeding programs

The efficacy of cinacalcet in the treatment of hyperparathyroidism in Turkish hemodialysis patient population

WOS: 000393291900012OBJECTIVE: Cinacalcet reduces parathyroid hormone levels by increasing the sensitivity of the parathyroid gland to calcium. in this study, we firstly aimed to evaluate the efficacy of cinacalcet in Turkish hemodialysis patients. MATERIAL and METHODS: 4483 hemodialysis patients were screened and 469 patients who had used cinacalcet were included in the study. the patients were divided into 4 groups according to drug usage durations (Group 1: 3 months, Group 2: 6 months, Group 3: 9 months and Group 4: 12 months). the patients' Parathormone, Ca, P and CaxP levels at the 3rd, 6th, 9th and 12th months were compared to the start of treatment and previous months. RESULTS: the levels of Parathormone, Ca, P and CaxP significantly decreased compared to their initial levels in all groups (from 1412 pg/ml to 1222 pg/mL for Parathormone, p< 0,001) in the 3rd month. However, this reduction was not continued in the subsequent months (Parathormone: 1381 pg/ml for the 12th month). CONCLUSION: Cinacalcet may not provide adequate benefit in control of hyperparathyroidism in Turkish hemodialysis patient population

The influence of hydrogen addition on the combustion characteristics of a common-rail CI engine fueled with waste cooking oil biodiesel/diesel blends

In this study, the effect of hydrogen assisted intake air on combustion characteristics of a diesel fuel-waste cooking oil biodiesel (WCOB) blend fueled CI engine has been extensively studied. While the diesel and B25 (75% diesel fuel+25% WCOB) fuels used as the main fuel were sprayed directly into the cylinder, the hydrogen, the secondary fuel was mixed with the intake air at 10, 20, 30 and 40 lpm flow rates and taken into the cylinder. The maximum in-cylinder pressure (CP) values decreased with B25 fuel compared to diesel fuel. But B25‑hydrogen dual-fuel mode operation exhibited higher maxium CP and RoPR value according to diesel fuel. It was seen that hydrogen has a more significant effect on premixed pilot fuel combustion phase compared to the diffusion combustion phase. It was observed that the combustion duration (CD) of neat B25 fuel lower than that of diesel fuel, generally. In case of B25‑hydrogen dual-fuel mode operation, CD increased depending on increasing hydrogen addition rate. It was seen that hydrogen enrichment has no adverse effect on ringing intensity (RI). © 2021 Elsevier B.V

Physical Fitness Levels of Young Adults With and Without Intellectual Disability

Intellectual disability (ID) and living in residential home settings may be a disadvantage for an active lifestyle and healthy aging. The purpose of this study was to determine physical fitness (PF) levels of women with mild intellectual disabilities (n=31; mean age 22.22+/-3.11 years), clients of residential homes, and to compare them to the PF levels of their control peers (n=31; 23.16+/-3.12 years of age). First, cardiovascular disease risk factors (CVD) of the participants were determined based on the information from residential home doctor, participants' health reports, and blood sample analyses. Health-related physical fitness parameters (balance, cardiorespiratory endurance, muscular endurance, and flexibility) were measured, and body composition and anaerobic power were assessed. The significant differences were found between the groups (p<.05) in body mass index, muscular endurance, maximum walking distance, peak VO2, balance, flexibility, and power. The results of the study indicated that the PF levels of women with ID were lower than those of their control peers. Women with ID should be encouraged to participate in physical activity programs to improve their physical fitness.Wo
