BACKGROUND Bisphenol A (BPA) and bisphenol A diglycidyl ether (BADGE), used in manufacturing coatings and resins, leach from packaging materials into food. Numerous studies suggested that BPA and BADGE may have adverse effects on human health, including the possibility that exposure to such chemicals can be superimposed on traditional risk factors to initiate or exacerbate the development of ob...

(57) ABSTRACT A method of reducing poWer consumption of a radio badge in a boundary detection localization system is disclosed, in Which the radio badge is carried by a tracked target and performs location sampling communication With an infra structure component of the localization system at the start and end of sampling time intervals such that positions of the radio badge can be estimated. Th...

While many animals display different colour patterns that signal different messages, some species use various tactics to separate between colour and pattern displays. The common chameleon (Chamaeleo chamaeleon) is capable of rapidly changing and separating among displays of colour patterns and ornaments. We used chameleons to study the contextual role of separation among colour and pattern disp...

The maintenance of honesty in a badge-of-status system is not fully understood, despite numerous empirical and theoretical studies. Our experiment examined the relationship between a status signal and winter survival, and the long-term costs of cheating, by manipulating badge size in male house sparrows, Passer domesticus. The effect of badge-size manipulation on survival was complex owing to t...

The formal Presidential regalia is an ornate chain from which is suspended the badge of the British Medical Association and below it the badge of the Society (Figure 1 ). The large badge is engraved on the front 'British Medical Association Belfast 1909' (Figure 2). It was presented by the medical profession of Ulster to Sir William Whitla who was President of the BMA when it met in Belfast in ...

OBJECTIVES Bisphenol A diglycidyl ether (BADGE) is a liquid compound obtained by condensation of two molecules of epichlorohydrin with one molecule of bisphenol A. General and reproductive toxicity with BADGE has been reported higher than 1000 mg/kg/day. This study was performed to show the effects of acute exposure to BADGE below 1000 mg/kg/day on the testis in adult male rats. METHODS BADGE...

Epoxy resins find widespread use as adhesives and coatings in the construction and food industries. The majority of the products are based on resins that use bisphenol A diglycidyl ether (BADGE) as a precursor. This raises the question if BADGE could be a potential source of bisphenol A (BPA). The recent paper by Perez et al. (1) on the estrogenicity of BPA and some of its analogs and derivativ...

This paper describes the development of a new type of personal radiation dosimeter that combines the excellent features of optically stimulated luminescence (OSL) with the convenience of Panasonic type readers. The specification required for the badge in world-wide application is first discussed. The dosemeter is a Panasonic type dosemeter with OSL detectors replacing the thermoluminescence dos...
