Çalışmamızda Samsung PLCC4 LED ve elektronik bileşenlerinin jonksiyon sıcaklığı üzerinde via etkisi hesaplamalı akışkanlar mekaniği analizleri ile araştırılmıştır. Analizlerde FloEFD 17.4 hesaplamalı akışkanlar dinamiği ticari programı kullanılmıştır. Elektron…
Bu çalışmada yüksek ticari saflıkta (%99,8) alüminyum ve çinko elementleri kullanılarak bir adet ikili Al-35Zn alaşımı üretildi. Alaşım elementlerinin ergitilmesinde orta frekanslı bir indüksiyon ocağı kullanıldı. Ergimiş durumdaki sıvı metal oda sıcaklığınd…
Bu çalışma ile bireylerin renk tercihlerinin aldıkları eğitime göre değişip değişmediği araştırılmaktadır. Çalışmada çevresel imajı oluşturan ‘renk’ kavramı bağımlı değişken olarak, bireylerin eğitim durumu ise bağımsız değişken olarak ele alınmış ve bu iki …
The updated structural discontinuities of Turkey are determined utilizing Bouguer gravity data in this study. Total horizontal gradient technique was used to reveal the lineaments. This technique is applied to first vertical derivative values of regional gra…
The hot-injection is one of the most used chemical synthesis methods to be able to produce nano- and/or micron sized particles in a liquid medium. Synthesis of nanoparticles of group II-VI semiconductors such as ZnO, ZnSe, CdSe and IV and V metals such as Pb…
The hexakis-[30-(10,20,30-thiadiazol-40-yl)phenoxy] (5) and hexakis-[50-oxy-20- methylbenzothiazole] (6) cyclotriphosphazene derivatives were synthesized by Çiftçi et al. in 2017. The structural parameters for the compound (6) and the fluorescence properties…
Using pure water in the determination of the fiber density is a well-known technique and a simple method. But, it is known that using water in the determination of textile fibers is not sufficient. Thus, the aim of this study is to produce a simple technique…
Childhood is a sensitive period in which human life is shaped and the environment in which the child interacts is of great importance. Since the child has a constantly evolving and changing structure, its furniture needs to be changed in terms of both functi…
Trend analysis of precipitation play a significant role in the efficient water resources management, especially in arid and semi-arid regions. In this study, 48 years-long (1970-2017) annual precipitation data monitored at nine selected stations (Mardin, Adı…
It was aimed to find the structural discontinuities of the Eastern Anatolia Region by using horizontal gradient magnitude technique. When determining the structural discontinuities of the region, the maximum amplitudes of the horizontal gradient magnitude we…
Nükleer endüstri üstün özelliklere sahip malzemelerin seçimini gerektirir. Halen dünya çapında elektrik üretiminin % 15’ ini oluşturan 440’ tan fazla ticari nükleer reaktör vardır. Dünyanın nükleer güç santralleri filosu 20 yaşından büyüktür. Bu nükleer güç …
Palladium-catalyzed Suzuki Miyaura cross coupling reactions (SM Coupling) are made using organoboronic acid and halides. 9-(4-anthracene-9-yl-phenyl)-9H-carbazole (III) was synthesized by using Ullman and Suzuki coupling reactions. Structural analysis of the…
Cities have changed in every sense from past to present. For example, demands and needs have increased and consequently changed. As a result; the cities have a complex structure that is not stable. In this process, declining green areas have directed people …
Urban public spaces which have a place in urban design projects with different scales and degrees, are important living/living parts of the city used by everyone. These places are primarily used for mobility and access but also for official social events. In…
The (9) and (12) compounds are optimized at B3LYP/6-31G(d,p) level in gas phase. The calculated bond length and bond angles are compared with experimental values. Also, the calculated vibrational frequencies are assignment for mentioned compounds according t…
Historical structures that reflect all the social, cultural, economic and political characteristics of societies are important symbols of that society. This structure, which has come from the past to the present, needs to be transferred to the next generatio…
Transition metal complexes are playing an important role the field of bioorganic chemistry. it has been attempted to investigate the anti-cancer properties of complexes of 2-benzimidazole derivatives formed with various metal atoms [1-2]. In these examinatio…
In this study, natural colored (dark gray) wool and white angora fibers were firstly hand-spun and then hand knitted fabrics were produced from these yarns. Then, mass per unit area, air permeability and the hand of the fabrics were compared statistically. I…
Energy demand in the 21st century is increasing continually. This increase in energy demand is one of the factors affecting the increase in universal problems. Energy is produced using both renewable and non-renewable resources. Therefore, energy consumption…
