In scaled CMOS processes, the single-event effects generate missing output pulses in Delay-Locked Loop (DLL). Due to its effective sequence detection of the missing pulses in the proposed Error Correction Circuit (ECC) and its portability to be applied to any DLL type, the ECC mitigates the impact of single-event effects and completes its operation with less design complexity without any concer...

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...

Relation to high absorption fraction of Tc sestamibi by kidneys in heart scan and these organs are near to generation organs (Ovaries and uterus). Urinary system (kidneys and urinary bladder) are specified as sources organs. The main object of this study is to determine the absorbed dose in these critical organs. we have set amount of absorbed fraction radiopharmaceutical in position of kidneys...

Studies were carried out to determine the contribution of secondary photons to the calibration set-up of a Secondary Standard Dosimetry Laboratory. In these studies the response of LiF:Mg TLD-100 to known exposures using Cs-137 panoramic-source were investigated. Each TLD chip showed a linear dose response to radiation, demonstrating a typical characteristic of LiF:Mg chips. Whilst TLDs showed ...

The aim of this study was to examine the colonization of Streptococcus mutans and Streptococcus sanguinis in the oral cavity and the association with severe early childhood caries (S-ECC). Saliva and plaque samples were collected from 14 S-ECC children and 8 caries-free (CF) children. All S-ECC children were S. mutans positive; 100% of CF children and 93% of S-ECC children were S. sanguinis pos...

Objective: Ethanol extract of Cajanus cajan (L.) Millsp. (Pigeonpea) leaves (ECC) was investigated for its hepatoprotective activity. Methods: Different groups of Wistar albino rats were administered with paracetamol (500 mg/kg, p.o., once daily for 7 days) for induction of hepatotoxicity. ECC (100, 200 and 300 mg/kg/day) and silymarin (25 mg/kg/day) were administered to the paracetamol induced...

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...

Engineered cementitious composite (ECC) is a new generation of fiber-reinforced concrete with high ductility and exceptional crack control capabilities. However, ECC can suffer substantial reduction in when exposed to elevated temperatures resulting loss crack-bridging ability. In this study, the effect adding basalt fiber (BF), which an inorganic high-temperature resistance for production ECC,...
