    In this study, the evaluability of lower calorific B3 coal seam belonging to Seyitömer lignite operations which is about 25 km away from Kütahya was researched. The coals pertaining to the B1 and B2 seams in the region are used as fuel in thermal power plant after the washing process. However, B3 seam cannot be evaluated which contains 28.7% humidity, 44.69% ash, 13.81% volatile matter, 12.8% fixed carbon and 1543 kcal/kg lower calorific value. For this purpose, sink-float tests were carried out on representative samples taken for evaluation of B3 coal seam. As a result of float-sink tests on different particle sizes, the optimum results were obtained at particle size intervals of -31.5 + 16 mm (72% yield, 25% ash, 1425 kcal / kg calorific values) and -63 + 31.5 mm (76% yield, 22% ash, 1751 kcal / kg calorific value). Also, optimum density was measured to be 1.5 gr/cm3. It has been decided that while coarse particle size scan be enriched with the jig method, the fine particle size scan be enriched with the shaking table according to the results of the sink-float. As a result of enrichment experiments with jig, the lower calorific value of clean coal was obtained as 2903 kcal/kg, while the schist was obtained as 687 kcal/kg at particle size of -63 + 31.5 mm. Also, ash contents were 15.14% and 75.16% respectively. On the other hand, as a result of enrichment experiments with shaking table, the calorific value of clean coal was obtained as 2403 kcal/kg while the schist was obtained as 385 kcal/kg at particle size of -16 + 12, 5 mm. Ash content were also obtained as 16.96% and 68.85% respectively. According to these results, the calorific value of B3 coal seam has been made suitable for being used at thermal power plant

Ayrıca çalışanların demografik özellikleri ile tükenmişlik düzeyleri ve örgütsel bağlılık seviyeleri arasında anlamlı ilişkiler bulgulanmıştır. Burnout syndrome and organizational commitment are among one of the most searched topics in social sciences in recent years. The aim of this study is to specify levels of burnout syndrome and organizational commitment and; the employees of fisheries and aqauculture enterprises. To realize this aim, this investigation is applied on 125 employee from three different fisheries and aquaculture enterprises in Akdeniz Region. Results of analysis,siginificant relationships found between burnout and organizational commitment levels of employees. Furthermore, siginificant relationships are found between demographic characteristics, burnout and organizational commitment levels of employees

    Background/aim: Oligometastatic disease for nonsmall cell lung cancer (NSCLC) patients is generally thought to represent a better prognosis with a quieter biology, limited number of disease sites and long-term disease control. In this study, we aimed to determine the efficacy of radical treatment options for patients with oligometastatic NSCLC. Materials and methods: This retrospective trial included totally 134 patients with oligometastatic NSCLC. The presence of oncodriver mutation, tumor stages and nodal status, the number of metastases and involved metastatic site, treatment of primary tumor and oligometastasis, response rate, overall survival (OS) and progression-free survival (PFS) were evaluated. Results: Of 134 patients 66.4% were defined as adenocarcinoma, 26.1% were squamous cell carcinoma and 7.5% of patients were in other histology. Based on the treatment of primary tumor, in 36 patients (26.9%) curative surgery has undergone, in addition, 19 (14.2%) patients were received chemotherapy, 73 (54.5%) were treated with chemoradiotherapy, while immunotherapy and targeted therapy were used in 1 (0.7%) and 2 (1.4%), respectively. The preferred treatment for oligometastatic lesions were SBRT in 72.4% of patients, surgery in 10.5%, and both SBRT and surgery in 17.1% of patients. At the median follow up of 31.3 months (range: 9.5–48.5), the median PFS and OS times were 17 and 24.4 months, respectively. Moreover, OS-2 after progression was also 7.2 months. Conclusion: Based on our real-life experience, we demonstrated a significant correlation between good response to first treatment and survival in oligometastatic disease, we also understand that local ablative treatment modalities prolong and also delay both OS and PFS in oligometastatic NSCLC patients OS-2

    Patients with Black Hip and Black Knee Due to Ochronotic Arthropathy: Case Report and Review of Literature

    Abstract Ochronotic arthropathy is a manifestation of longstanding alkaptonuria. With increasing age, an accumulation of pigment deposits of homogentisic acid in the joint cartilage results in ochronotic osteoarthritis. We present a case of a 62-year-old female who underwent staged left uncemented total hip and right cemented total knee arthroplasty for osteoarthritis secondary to ochronosis

    Analysis of the common genetic component of large-vessel vasculitides through a meta- Immunochip strategy

    Giant cell arteritis (GCA) and Takayasu's arteritis (TAK) are major forms of large-vessel vasculitis (LVV) that share clinical features. To evaluate their genetic similarities, we analysed Immunochip genotyping data from 1,434 LVV patients and 3,814 unaffected controls. Genetic pleiotropy was also estimated. The HLA region harboured the main disease-specific associations. GCA was mostly associated with class II genes (HLA-DRB1/HLA-DQA1) whereas TAK was mostly associated with class I genes (HLA-B/MICA). Both the statistical significance and effect size of the HLA signals were considerably reduced in the cross-disease meta-analysis in comparison with the analysis of GCA and TAK separately. Consequently, no significant genetic correlation between these two diseases was observed when HLA variants were tested. Outside the HLA region, only one polymorphism located nearby the IL12B gene surpassed the study-wide significance threshold in the meta-analysis of the discovery datasets (rs755374, P?=?7.54E-07; ORGCA?=?1.19, ORTAK?=?1.50). This marker was confirmed as novel GCA risk factor using four additional cohorts (PGCA?=?5.52E-04, ORGCA?=?1.16). Taken together, our results provide evidence of strong genetic differences between GCA and TAK in the HLA. Outside this region, common susceptibility factors were suggested, especially within the IL12B locus

    Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries
