The University of Texas M.D. Anderson Cancer Center (UTMDACC) has extensive experience with thermoluminescent dosimetry (TLD) as a quality assurance tool for output and energy monitoring of radiation therapy beams. Over the past 25 years the TLD results of the monitored institutions, commissioning data for TLD readers, the characterization data of lithium fluoride TLD-100 powder and the records...

To investigate the role of T lymphocytes in osteoclastogenesis, we performed in vivo depletion of CD4 and/or CD8 T lymphocyte subsets and evaluated in vitro osteoclast-like cell (OCL) formation. T lymphocyte depletion (TLD) with mAbs was confirmed 24 h later by flow cytometry. OCL formation was stimulated with 1, 25-dihydroxyvitamin D(3) (1,25-(OH)(2)D(3)) in bone marrow and with recombinant mo...

We present a control plane for operators of Top-level Domains (TLDs) in the Domain Name System (DNS), such as “.org” and “.nl”, that enables them to increase the security and stability of their TLD by taking on the role of a threat intelligence provider. Our control plane is a novel system that extends a TLD operator’s traditional services and detects potential threats in the TLD by continuousl...

Mutations in the Drosophila tolloid (tld) gene lead to a partial transformation of dorsal ectoderm into ventral ectoderm. The null phenotype of tld is similar to, but less severe than decapentaplegic (dpp), a TGF-beta family member required for the formation of all dorsal structures. We have cloned the tld locus by P element tagging. At the blastoderm stage, tld RNA is expressed dorsally, simil...

BACKGROUND Third Location Decompression (TLD) is the process through which personnel, returning from combat operations, begin to psychologically 'unwind'. Decompression comprises welfare activities, such as contacting home, beach events, social events, psycho-educational briefings and controlled re-introduction to alcohol. AIMS To assess the subjective utility of decompression by surveying al...

BACKGROUND Previous studies have reported that children score better in language tasks using sung rather than spoken stimuli. We examined word detection ease in sung and spoken sentences that were equated for phoneme duration and pitch variations in children aged 7 to 12 years with typical language development (TLD) as well as in children with specific language impairment (SLI ), and hypothesiz...

The Radiological Physics Center (RPC) has been utilizing TLD to verify photon-beam output, and electron-beam output and energy for many years. The RPC currently monitors over 1200 institutions, monitoring 4000 photon and 3500 electron beams per year. Control TLD, irradiated on one specific Co-60 machine, are used for a performance check of our TLD system. Analysis of these data over 5 years, re...

Personnel monitoring of more than 40,000 radiation workers in India is being carried out routinely using a Bhabha Atomic Research Centre (BARC) made thermoluminescent dosimeter (TLD) badge based on CaSO4:Dy phosphor embedded in Teflon discs [1], and a photographic film badge. Till recently the TLD badges were read using the manual type TLD badge reader system with an external interface unit for...

BACKGROUND AND PURPOSE Since 1969 the International Atomic Energy Agency (IAEA), together with the World Health Organization (WHO), has performed postal TLD audits to verify the calibration of radiotherapy beams in developing countries. MATERIALS AND METHODS A number of changes have recently been implemented to improve the efficiency of the IAEA/WHO TLD programme. The IAEA has increased the n...

BACKGROUND Third location decompression (TLD) refers to the initial process, undertaken by military personnel at the end of an operational deployment, whereby adjustment from military operations commences. TLD has been shown to be useful for personnel in formed units (FU). AIMS To examine the subjective utility of TLD for personnel deployed as individual augmentees (IAs) by comparing their ex...
