Although reinforced concrete columns are often subjected to concentric loads, especially side columns are also subjected to eccentric loads and try to carry axial loads under the influence of bending moments. In this study, it is aimed to experimentally investigate concentric and eccentrically loaded reinforced concrete columns strengthening with carbon fiber reinforced polymer (CFRP) strips. For this purpose, 6 large-scale test elements were fabricated. Two of these test elements were chosen as reference. The remaining 4 test elements are strengthened with CFRP strips. Loading type (concentric and eccentric) and anchor usage were determined as variables. The strip width and spacing were kept constant. As a result of the experimental study, the maximum load carrying capacity, initial stiffness, ductility and energy dissipation capacity of the test elements were calculated and the results were compared.","PeriodicalId":430699,"journal":{"name":"Bayburt Üniversitesi Fen Bilimleri Dergisi","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116024376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Her türlü sosyal ve kültürel sınıftan, farklı cinsiyet, yaş grubu, fiziksel özellik ve yeterliliğe sahip hasta, hasta yakını ya da sağlık personeli; hastalık tedavisi ya da sağlık kontrolü nedeniyle bu yapıların kullanıcılarını oluşturmaktadır. Bu durum hastanelerin yalnızca erişilebilirlik standartlarıyla değil; aynı zamanda evrensel tasarım yaklaşımıyla da ele alınmasını gerektirmektedir. Evrensel tasarım, uyum ve özel tasarıma gerek duymadan, mümkün olduğu kadar en geniş kapsamda, herkesin kullanabileceği ortamların veya ürünlerin tasarlanmasını ifade eder. Buradan hareketle çalışmanın amacı, hastane tasarımında evrensel tasarım ölçütlerinin uygulanma biçim ve düzeylerini değerlendirmek ve irdelemektir. Bu amaç doğrultusunda nitel ve nicel veri toplama araçlarından yararlanılmış; yerinde tespit ve gözlem, ölçüm ve fotoğraflama teknikleri bir arada kullanılmıştır. Çalışma alanı Trabzon- Kaşüstü Kanuni Eğitim ve Araştırma Hastanesi olup irdelemeler 2019 yılı ortalarına kadar çalışma alanından elde edilen veriler üzerinden tamamlanmıştır. Çalışmada, poliklinik alanlarının genel kullanımda olan otopark alanları, girişler, yatay ve düşey dolaşım alanları, danışma, hasta kayıt ve bekleme alanları ile tuvaletler ele alınmıştır. Öncelikle her bir bölüm için kontrol listeleri oluşturulmuş, toplamda 244 değerlendirme ölçütü çalışma alanında uygulanmıştır. Böylece, herkes için kullanım açısından eksik, düzeltilmesi ya da geliştirilmesi gereken özellikler ortaya çıkarılmıştır. Araştırma sonucunda hastanenin yönetmeliklere uygun tasarlanmış olması nedeniyle yaklaşım ve kullanım için uygun boyut ve mekân konusunda sorunların daha az olduğu; ancak özellikle basit ve sezgisel kullanım ve algılanabilir bilgi konularında eksikliklerin fazla olduğu tespit edilmiştir.","PeriodicalId":430699,"journal":{"name":"Bayburt Üniversitesi Fen Bilimleri Dergisi","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130048694","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, conformational analysis was performed using the Spartan06 program to elucidate the structure of 1,4-Bis(2-chloro-4-nitrophenyl)piperazine (C16H14Cl2N4O4). Among the conformations determined as a result of the conformation analysis, the molecular structure with the lowest energy was determined. DNA is an important target for anticancer molecules. For this reason, the interaction of 1,4-Bis(2-chloro-4-nitrophenyl)piperazine with DNA (PDB ID: 1BNA) was investigated through docking simulations. The obtained lowest energy conformer of the title molecule was taken as the starting geometry of the ligand for docking simulations with target DNA. As a result, the binding affinity and the binding mode of the title molecule with DNA were evaluated. 1,4-Bis(2-chloro-4-nitrophenyl)piperazine has -7.5 and -7.4 kcal/mol binding affinities to DNA, in two different sites. Depending on the molecular docking studies, the 1,4-Bis(2-chloro-4-nitrophenyl)piperazine was predicted to possess strong anti-tumor effects.","PeriodicalId":430699,"journal":{"name":"Bayburt Üniversitesi Fen Bilimleri Dergisi","volume":"214 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132360986","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a case, a gearbox part with a high scrap rate of dart defect is considered. First of all, the parameters (mechanical properties of the mold sand, casting temperature, etc.) that are effective in the formation of the dart defect have been checked. According to the outputs of the Magmasoft © Simulation software, in order to prevent the cause of the dart defect in the part made of EN-GJL 300 material, it was observed that the runner ingates did not work in balance as a result of faulty in runner design. The gating system was redesigned with the basic approaches of fluid mechanics, and with the simulation made before the application on pattern, a significant improvement was observed compared to the outputs of the first simulation study. It has been seen that the root cause of the dart defect, which is generally known as sand expansion and the solution of which is sought in the sand parameters, may also be caused by the runner system. By evaluating the general literature and process control results with the simulation software result outputs, the cause of the dart defect was determined and the scrap rate of the part has been reduced by eliminating this defect type.","PeriodicalId":430699,"journal":{"name":"Bayburt Üniversitesi Fen Bilimleri Dergisi","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114699844","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
