İşlier, A. Attila; Altuntas, Serkan
Occasionally certain tasks in an assembly line balancing problem are required to be kept together due to some specific reasons. These tasks are attained to the same work stations. Such problems are called as ‘Assembly Line Balancing Problem with Task Related Constraints (ALBTRC)’. Certain situations like awkward product construction, simultaneous operations or specific requirements leading to zoning and positional constraints like utilization of common resources as tools, jigs and fixtures are implemented thanks to these supplementary constraints. Additionally, materials handling and tooling costs, distances, set-up and lead times are also reduced. Literature on ALBTRC seems quite rare compared to Classical Line Balancing papers, although ALBTRC is one of the common real life balancing problems. This study aimed to develop and implement a novel line balancing method for a manufacturing concern where known methods are impractical to employ due to some specific positional constraints. ‘Largest Candidate Method’ known as a simple but effective tool is modified for this purpose first. Then a thorough ‘method and time study’ is conducted to get the necessary data to utilize that method. As a result, more efficient alternatives are generated and presented to decision maker

The Author who examines divine authority in his article, differentiated between the authority in the Qur'an to the authority asserted by contemporary Islamic movements. According to him, contemporary Islamists have been colored by attempts to counter Western concepts of authority, government and legitimacy by taking the concept of Qur'anic authority out of context and without considering the Qur'an's structural integrity, universality and final significance. According to the author, the authority of the Qur'an is like human authority, because it functions through a human reading and application.

The aim of this study is to determine the alkali-silica reaction (ASR) related characteristics of crushed stones that are produced from rocks of perlite, andesite and limestone when zeolitic tuff (ZT) is used in the mortar mix as cement replacement in different ratios. Accelerated mortar bar experiments in accordance with ASTM C 1260 were carried out on crushed stone aggregate samples to determine the ASR. CEM I 42.5 R type cement was replaced by ZT material in the following ratios: 0, 10, 20, 30 and 40%; in order to investigate the effects of replacement on the ASR pertaining to the aggregate types, 45 mortar bar pieces were produced. The length change values of the samples were measured on the 3, 7, 14, 28, 42, 56 days according to the accelerated mortar bar method. Measured length changes for the control samples on 14(th) day were found to be 0.570% at the level of potentially harmful for perlite, 0.101% at the level of critic for andesite and 0.061% at the level of harmless for limestone. Length changes at the harmful levels were taken under control for perlite at 30 and 40%, for andesite at 20, 30 and 40% ZT replacement ratios. Length change values of all samples decrease as ZT replacement increases. As a result, ZT replacement is effective to suppress the ASR of reactive aggregates.

Gursoy, Recep; Ziyagil, Mehmet Akif; Sahin, Suleyman; Dane, Senol; Warnick, JE; Martin, WD
Handedness is a preference for the use of one of the right- or the left-hands. In the large majority of right-handers, speech is controlled by the left side of the brain. Also, the right hemisphere of the brain is usually specialized for recognizing and remembering faces and understanding relationships in space. We live in a right-handed world and that left-handers have an inherent disadvantage in using tools designed for right-handers. Left-handed persons are believed to have better developed motor, attentional and spatial functions. Some studies have explored a possible correlation between left-handedness and enhanced performance in specific sports such as baseball, cricket, fencing, soccer and tennis. The rate of the left-handed boxers was higher compared to the right-handed ones in the National Road Sport Men Boxing Club in Turkey. These results may be associated with two suggestions: 1. the left-handed subjects have an intrinsic advantage over right-handers due to superior spatio-motor skills, 2. advantage in the left-handed boxer and the left-handed other athletes may result from the nature of the game (boxing) or frequency-dependent strategic advantage.

Many factors to be appropriately addressed in moving towards energy sustainability in Turkey are examined. These include harnessing sustainable energy sources, utilizing sustainable energy carriers, increasing efficiency, reducing environmental impact and improving socioeconomic acceptability. The latter factor includes community involvement and social acceptability, economic affordability and equity, lifestyles, land use and aesthetics. On the other hand, Turkey, with its young population and growing energy demand per person, its fast growing urbanization, and its economic development, has been one of the fast growing power markets of the world for the last two decades. Turkey is heavily dependent on expensive imported energy resources that place a big burden on the economy and air pollution is becoming a great environmental concern in the country. In this regard, renewable energy resources appear to be the one of the most efficient and effective solutions for clean and sustainable energy development in Turkey. Turkey's geographical location has several advantages for extensive use of most of these renewable energy sources. This article presents a review of the potential and utilization of the energy sources in Turkey.

Yaşar, Ahmet; YaylI, Nuran; Usta, Asu; YaylI, Nurettin
Photodimerization reactions of compounds 4-6 gave four new cyclobutane-containing compounds (7-9) with full control over the stereochemistry at the four stereogenic centers. These new cyclobutane- containing compounds had β-truxinic (7a), δ-truxinic (7b and 9), and ε-truxillic (8) structures. However, o-, m-, and p-hydroxy 4-azachalcones (1-3) did not give photochemical cyclization products under any conditions (in solvent or in their solid or molten states). Experimental data suggested the possibility of frontier orbital control over stereochemical behavior, so some theoretical calculations were performed. Full geometrical optimization of compounds 1-9 was performed via DFT B3LYP/6-31+G**, and their electronic structures were also investigated. The geometries of the singlet and triplet states were initially optimized by density functional theory (DFT) and the configuration interaction singles (CIS) B3LYP/3-21 +G**level. An additional calculation was performed for the triplet state using the ground-state geometry. The possible photochemical dimerization products of compounds 7-9 (a-g) and the intrinsic reaction coordinates (IRCs) of the reactions of compounds 4-6 were calculated theoretically by the DFT/3-21+G**method. The configurations (reactant, transition state, product, and reaction pathway) corresponding to the stationary points (minima or saddle points) were determined. The intrinsic reaction coordinates were followed to verify the energy profiles that connect each TS to the appropriate local minimum. The dimeric products expected from the calculations coincided with the dimers produced experimentally.
