This study was conducted to evaluate the anthelmintic effectiveness of Albizia anthelmintica, as a first step in investigating the hypothesis that livestock self-medicate. In July 2006, an observational study was conducted with 56 young female lambs, to validate A. anthelmintica efficacy. Faecal egg per gram for Coccidia, Strongyle-type, Monezia, Strongyloides and Dicrocoelia eggs were counted ...

Radiotherapy planning is a complex problem which requires both expertise and experience of an oncologist. A Case Based Reasoning (CBR) system is developed to generate dose plans for prostate cancer patients. The proposed approach captures the expertise and experience of oncologists in treating previous patients and recommends a dose in phase I and phase II of the treatment of a new patient cons...

Radon studies have been conducted in many countries of the world in indoor air but such studies in drinking waters are sparse. We present the results of Rn activity concentration measurements in drilled and dug well drinking waters from three large cities in Ogun State, southwestern Nigeria. The measurements were done suing high-resolution high-purity germanium (HPGe) detector (Canberra Industr...

Th e response of diff erent fertilizer doses was studied on the ratoon crop as well as main crop. Th e diff erent fertilizer doses under the study were F1 (N=90, P2O5 = 45, K2O=50, S=13, Zn = 4: in kg ha-1), F2 (N=105, P2O5 = 55, K2O=60, S=13, Zn = 4: in kg ha-1), F3 (N=120, P2O5 = 65, K2O=70, S=13, Zn = 4: in kg ha-1), F 4(N =135, P2O5 =75, K2O=80, S=13, Zn=4: in kg ha-1) and F5 (N=150, P2O5 =...

ALLEGRO is an European project investigating health risks following radiotherapy. In this frame our group has performed out-of-field dose measurements to compare different types of radiation therapy, studying the influence of the delivery technique and the beamline structure on the dose profile. The data obtained can be used as validation of Monte Carlo models and for assessing the risk of deve...

Control of within-herd transmission of Salmonella is important for reducing the prevalence of this organism on pig farms and for preventing Salmonella-contamination of pork. At the farm level, understanding the within-herd transmission of Salmonella can lead to more effective control. Salmonella infection is dependent on the inoculation dose; hence, quantitative evaluation of Salmonella shed in...

This study presents the summary of historical exposures, measurement practice and evolution of the recording of the individual doses of medical radiation workers during 1950–2003 in Lithuania. The aim of this study is to present occupational exposure of medical radiation workers in Lithuania since the earliest appearance period. Data from publications have been used for the earliest two periods...

The present assessment places hormetic dose responses within an historical context, documenting its origin, rejection by the biomedical community during the early decades of the 20 due to its close association with homeopathy and its revitalization during the later decades of the past century as the biomedical and toxicological communities became very interested in low dose effects of drugs and...

Several methods for determining exchangeable sodium in human subjects by using the gammaray emitter Na22 (half-life 2.6 years) in conjunction with measurements of body radioactivity have previously been described (1-3). With these methods, it is possible to make repeated exchangeable sodium determinations over a period of several weeks or months after giving a single tracer dose of the radioiso...
