From the morality of living to the morality of sying: hunger strikes in Turkish prisons

Political hunger strikes have been part of the debates on human rights in many countries around the world. This paper explores the preconditions for and motives behind hunger strikes in Turkey by conceiving the hunger strikers as a part of citizenship politics through which strikers not only express their views against certain common issues, but also declare total opposition to an unjust condition within their political community. The paper focuses on the question of why some such “citizens” choose to participate in hunger strikes, which appears as an individual commitment to achieve a certain common objective. In doing so, the meaning of the experiences of hunger strikers and their universal right to live are elaborated in relation to their political and moral views. Hunger strikes are suggested to be seen as voluntary fasting, undertaken as a means of civil disobedience against an injustice within the context of citizenship. As examples of non-violent political acts, hunger strikes are not only part of citizenship politics but also expressions of commitment to achieving one’s goals through non-aggressive means for the common good of all citizens. Moreover, they can also be considered examples of martyrdom/heroism because hunger strikers altruistically risk their life for a public cause. As a particular altruistic act, hunger strikes can also be viewed as an effective form of communication directed toward fellow citizens. Moreover, they are expressions of self-determination for having control over and for one’s own life conditions. Finally, hunger strikes can be conceptualized as a struggle for transforming the configuration of structures and practices of citizenship about which one is passionately concerned. In this context, hunger strikes seem to be struggles for recognition in a relationship between two subjects, in which one subordinates the other

A Survey On Multi Trip Vehicle Routing Problem

The vehicle routing problem (VRP) and its variants are well known and greatly explored in the transportation literature. The vehicle routing problem can be considered as the scheduling of vehicles (trucks) to a set of customers under various side constraints. In most studies, a fundamental assumption is that a vehicle dispatched for service finishes its duty in that scheduling period after it returns back to the depot. Clearly, in many cases this assumption may not hold. Thus, in the last decade some studies appeared in the literature where this basic assumption is relaxed, and it is allowed for a vehicle to make multiple trips per period. We consider this new variant of the VRP an important one with direct practical impact. In this survey, we define the vehicle routing problem with multiple trips, define the current state-of-the-art, and report existing results from the current literature

Variable Temperature-Scanning Hall Probe Microscopy (VT-SHPM) with GaN/AlGaN Two-Dimensional Electron Gas (2DEG) Micro Hall Sensors in 4.2-425K range, Using Novel Quartz Tuning Fork AFM Feedback

In this report, we present the fabrication and variable temperature (VT) operation of Hall sensors, based on GaN/AlGaN heterostructure with a two-dimensional electron gas (2DEG) as an active layer, integrated with Quartz Tuning Fork (QTF) in atomic force-guided (AFM) scanning Hall probe microscopy (SHPM). Physical strength and wide band gap of GaN/AlGaN heterostructure makes it a better choice to be used for SHPM at elevated temperatures, compared to other compound semiconductors (AlGaAs/GaAs and InSb), which are unstable due to their narrower band gap and physical degradation at high temperatures. GaN/AlGaN micro Hall probes were produced using optical lithography and reactive ion etching. The active area, Hall coefficient, carrier concentration and series resistance of the Hall sensors were ~14m x 14m, 10m7/G at 4.2K, 6.3 x 1012cm-2 and 12k7 at room temperature and 7m7/G, 8.9 x 1012cm-2 and 24k7 at 400K, respectively. A novel method of AFM feedback using QTF has been adopted. This method provides an advantage over STM feedback, which limits the operation of SHPM the conductive samples and failure of feedback due to high leakage currents at high temperatures. Simultaneous scans of magnetic and topographic data at various pressures (from atmospheric pressure to high vacuum) from 4.2K to 425K will be presented for different samples to illustrate the capability of GaN/AlGaN Hall sensors in VT-SHP
