The Drosophila tolloid (tld) and tolloid related (tlr) gene products belong to a family of developmentally important proteases that includes Bone Morphogenetic Protein 1 (Bmp1). Tld is required early in Drosophila development for proper patterning of dorsal embryonic structures, whereas Tlr is required later during larval and pupal stages of development. The major function of Tld is to augment ...

Empirical evidence contained in open digital badges has the capability to change educational curricula, assessments, and priorities. Because badge data in educational, social media, and workforce contexts is publicly available, questions of privacy and ethics should be scrutinized. Due to change driven by digital transparency, ethical questions at the intersection of learning analytics and the ...

Companies are encouraging and incentivizing contributors of online word-of-mouth (WOM) through gamification elements such as badges, mayorships, points, and such. We study how gamification elements, which capture and signal contributors’ accumulated expertise, affect consumers’ perception of contributors’ knowledge, and therefore the perceived effectiveness of their contributed WOM. We focus on...

Radiation dosimetry is fundamental in Medical Physics, involving patients and phantom dosimetry. In both cases thennoluminescence dosimetry (TLD) is the most appropriate technique for measuring the absorbed dose. In this paper thennoluminescence phenomenon as well as the use of TLD in radiodiagnosis and radiotherapy for in vivo or in phantom measurements is discussed. Some results of measuremen...

Preliminary TLD results from the DOSMAP experiment on ISS G. Reitz, S. Deme, I. Apathy 1 German Aerospace Center (DLR), Cologne, Germany 2 KFKI Atomic Energy Research Institute, Budapest, Hungary Abstract: The Dosimetric Mapping (DOSMAP) experiment, operated by Expedition Two onboard the ISS attempted to record and map radiation inside Space Station within a four month period. One of the severa...

BACKGROUND The accurate results of the individual doses in personal dosimety which are reported by the service providers in personal dosimetry are very important. There are national / international criteria for acceptable dosimetry system performance. Objective : In this research, the sources of uncertainties are identified, measured and calculated in a personal dosimetry system by TLD. METHO...

Tanısal radyolojide görüntü kalitesi önemli bir rol oynamaktadır. Dijital görüntülemenin, görüntüleri sayısal olarak elde etme, işleme ve saklama gibi avantajları vardır. dedektörlerin geniş dinamik aralığa sahip olması, daha iyi kalitede görüntülerin edilmesine olanak sağlar. Ancak hasta dozunda artışa sebep olabilmektedir. Bu nedenle optimizasyonunun, doz ölçümleri ile beraber yürütülmesi ger...

Thymineless death (TLD) in bacteria has been a focus of research for decades. Nevertheless, the advances in the last 5 years, with Escherichia coli as the model organism, have been outstanding. Independent research groups have presented compelling results that establish that the initiation of chromosome replication under thymine starvation is a key element in the scenario of TLD. Here we review...

OBJECTIVE Third Location Decompression (TLD) is an activity undertaken by UK Armed Forces (UK AF) personnel at the end of an operational deployment which aims to smooth the transition between operations and returning home. We assessed whether TLD impacted upon both mental health and postdeployment readjustment. METHOD Data collected during a large cohort study was examined to identify personn...
