This report describes the activities discussed at the 10th meeting of Section II of the Consultative Committee on Standards for the Measurement of Ionizing Radiations (Comité Consultatif pour les Etalons de Mesure des Rayonnements Ionisants, CCEMRI) held in May 1989 at Sèvres (France). Topics included present and future international comparisons of activity measurements, the status and possible...

Since the effectiveness of the development and operation of scientific facilities (especially those presenting specific hazards, such as ionizing radiations) relies heavily on state of the art practices, such as systems engineering and product lifecycle management, configuration management (CM) is becoming a key management process. However, while some maturity models exist to assess the degree ...

A synopsis of the available data on the radiosensitivity of female germ cells is provided, the reader being referred to recent comprehensive reviews for detailed information. The effects of ionizing radiations are considered in terms of age; germ cell stage and follicular development; type, quality, and physical factors of the exposure; and criterion chosen to assess the effect (cell killing, r...

Anterior congenital urethrocutaneous fistula is a rare anomaly that may present in an isolated fashion or in association with other anomalies of the genital urinary tract or anorectal malformations. A case of congenital anterior urethrocutaneous fistula nonassociated with other congenital anomalies in a 3-year-old male whose mother has been exposed to Chernobyl's nuclear fallout is described. T...

We report a case of 26-year-old woman at 10th week of gestation with cholestatic jaundice due to a common bile duct (CBD) stone managed by endoscopical retrograde cholangiopancreatography (ERCP). The procedure was successfully carried out without the use of ionizing radiations and under trans-abdominal ultrasonographical (US) control. A few cases are reported in literature in which ERCP was per...

Thyroid gland is butterfly shaped organ which consists of two cone lobes and belongs to the endocrine system. It lies in front of the neck below the adams apple. Thyroid disorders are some kind of abnormalities in thyroid gland which can give rise to nodules like hypothyroidism, hyperthyroidism, goiter, benign and malignant etc. Ultrasound (US) is one among the hugely used modality to detect th...

A mobile robot deployed for remote inspection, surveying or rescue missions can fail due to various possibilities and can be hardware or software related. These failure scenarios necessitate manual recovery (self-rescue) of the robot from the environment. It would bring unforeseen challenges to recover the mobile robot if the environment where it was deployed had hazardous or harmful conditions...

this research was conducted to evaluate the effects of electron beam (eb) and gamma ray (gr) radiations at doses of 25, 50 and 75 kgy on ruminal degradation kinetics of dry matter (dm) and crude protein (cp),andin vitro digestibility of canola meal (cm). the nylon bag technique and in vitro two step method were used for this aim. gr decreased ruminal degradability of dm (p<0.05), but eb had no ...

Wireless communications play a crucial role in human lives. The introduction of cellular network systems, broadband internet services and public Wi-Fi increase the connectivity between people exponentially. These wireless networks require antenna structures to propagate carrier waves through space these are located within Radiofrequency (RF) region electromagnetic spectrum. effects RF on people...
