Exposure to indoor radon has been determined to be the second leading cause of lung cancer after tobacco smoking. Canadian population risk of radon induced lung cancer was assessed in 2005 with the radon distribution characteristics determined from a radon survey carried out in the late 1970s in 19 cities. In that survey, a grab sampling method was used to measure radon levels. The observed rad...

The objective of this study was to examine the effects of Tithonia diversifolia as a supplementary forage on dairy cow performance and methane production. Nine lactating Holstein × Zebu dairy cows (519 ± 53.3 kg of body weight and 66 ± 13.3 d in milk) were paired by milk yield (21.3 ± 2.34 kg/d) and body weight and randomly assigned to three dietary treatments in a Latin square design with 21-d...

BACKGROUND Goat milk is reported to have antimicrobial activity of several pathogen bacteria that contained on food materials. The research related with antimicrobial activity of Alpha-S2 casein from goat milk is relatively less than other casein components. Herein, we reported the antimicrobial activity of caprine Alpha-S2 Casein (CSN1S2) protein from Ethawah breed goat milk and yoghurt in Gra...

The objective of this research paper is to create a public awareness in understanding the radon gas problem, discuss efficient data management methods and analyses of indoor radon gas concentrations, and mitigate the indoor radon gas concentrations to below acceptable level in the state of Ohio. The Ohio Radon Information System (ORIS) is a compendium of five databases or modules, viz. the “Hom...

Various essential and toxic heavy metals (Ca, Mg, Cu, Zn, Fe, Mn, Pb, Cd, Cr, and Ni) contents in various types of dried (infant formula and powdered) and fluid (fresh and processed) cow milk were assessed by atomic absorption spectrophotometry. The milk samples were collected from local markets of different parts of Peshawar city, Pakistan. Heavy metal concentrations varied significantly depen...

mChanges in the concentrations of free fatty acids (FFA) in bovine, ovine and caprine milk cheeses manufactured with a plant rennet (flowers of Cynara cardunculus) were studied throughout a 68-day ripening period. The long-chain saturated (C16 :0 and C18 :0) and unsaturated (C18 :1, C18:2, and C18 :3) FFA were the most abundant at all stages of ripening. The overall concentration of FFA in fres...

All methods for the estimation of aflatoxin M~ in milk involve extraction with organic solvents. In some methods, fresh milk or reconstituted powder is shaken with a suitable extractant so as to precipitate proteins and extract the toxin simultaneously, while in others a separate protein precipitant is used. In no method is protein precipitation complete, however, and at the extraction stage th...

Feed is a risk factor for poisoning the farm environment thus also fresh milk with pathogenic microorganisms of Listeria genus species. Listeria ivanovii, Listeria innocua, and Listeria seeligeri were isolated from 9.2%, but Listeria monocytogenes from 20.0% of feed samples. Most often different fodders (9.3%) and silage (4.7%) were contaminated with Listeria monocytogenes. Listeria genus speci...

The delivery method of [continuous (CONT) vs. every other day or intermittent (INT)] a glucogenic precursor (GP) which was contained glycerin (500 g/kg), mono-propylene glycol (250 g/kg), calcium propionate (150 g/kg), niacin (1 g/kg) and sulfate-Co (350 mg/kg) on performance, selected blood metabolites and liver enzymes were evaluated. Twenty-four multiparous Holstein fresh cows were ...

When compared to indoor radon concentrations, outdoor radon levels are generally low. Within the vicinity of a radon mitigation system, however, exhausted radon may cause unnaturally high levels of outdoor radon. A study was conducted over a period of three weeks on a home with a subslab depressurization mitigation system measuring outdoor radon concentrations correlated with wind speed. The da...
