Radon progeny: Behaviour and influencing factors in indoor and outdoor environment.

Radon progeny are the major contributor to inhalation dose to humans from natural sources of radiation. In addition, they are also used as tracers to study atmospheric phenomena. This makes it important to study the behaviour of Radon Progeny in both indoor and outdoor environment.

Significance of zinc-solubilizing plant growth-promoting rhizobacterial strains in nutrient acquisition, enhancement of growth, yield, and oil content of canola ( L.).

The present study was conducted with the aim to isolate, characterize, and identify the promising zinc-solubilizing rhizobacteria found naturally in the rhizosphere of canola ( L.) plants. The study investigated the roles of these strains in nutrient acquisition and assimilation of extracellular molecules such as hormones and secondary metabolites.

Thoron exposure in the radon-thoron prone area of the Adamawa Region, Cameroon.

The radon-prone area of the Adamawa region is characterized by high radon concentrations, where no low-risk area was observed. This study aims to investigate about indoor thoron concentration in this area, using RADUET detectors, thoron progeny monitors and DTPS/DRPS. The indoor thoron concentration ranged between 17 and 1000 Bq m, with an average of 131 Bq m.

Development of bacteria-based bioorganic phosphate fertilizer enriched with rock phosphate for sustainable wheat production.

Phosphorous (P) is a limiting macronutrient for crop growth. Its deficiency prevents plant development leading to an extensive use of phosphatic fertilizers globally. Bio-organic phosphate (BOP) fertilizer provides a sustainable approach to optimize nutrient availability, enhance crop yield, and mitigate the negative impacts of chemical fertilizers on the environment.

Mapping the Locations of Medical Specialists in the Ministry of Health's Hospitals in Malaysia by Specialty, Subspecialty and Area of Interest.

Mapping the distribution of medical specialists in the Ministry of Health (MOH) Malaysia facilities is expected to be more complex as the demand for specialty and subspecialty services increases in the future. A more robust and definitive gap analysis is needed to facilitate planning and resource allocation. The Medical Development Division developed a master list of framework of specialties, subspecialties and areas of interest, and Specialist Database Module in the Medical Programme Information System (MPIS) as tools to facilitate mapping of services.

Comparing the Positive Impacts and Stress Induction by Polyethylene Glycol (PEG 6000) Variable Levels on Canola ( L.) Growth, Yield, and Oil Contents.

Seed quality (i.e., emergence energy, viability, physical purity, size, weight) is a critical factor that influences the yield of crops.

COVID-19 exposure risk level in daily activity in adapting to new habits in the pandemic period.

Objective: Analyze how the COVID-19 exposure risk level in daily activity in adapting to new habits.

Methods: A cross-sectional online survey of the Indonesian adult population. Administered by an online questionnaire.

Wire mesh capped DRPS based bronchial dosimeter for personal inhalation dosimetry due to radon progeny.

A study has been carried out to experimentally determine the calibration factor (CF) of the passive bronchial dosimeter, which consists of a direct radon progeny sensor capped with a 100-wire mesh. First, the CF was determined in controlled environmental conditions simulated in a calibration chamber. With aerosol concentrations varying from 10p cmto 10p cmand relative humidity varying from 60% to 80% in the chamber, CF was observed to be nearly constant with an average value of (3.

Inhalation exposures due to radon and thoron ((222)Rn and (220)Rn): Do they differ in high and normal background radiation areas in India?

In India, High Background Radiation Areas (HBRAs) due to enhanced levels of naturally occurring radionuclides in soil (thorium and, to a lesser extent, uranium), are located along some parts of the coastal tracts viz. the coastal belt of Kerala, Tamilnadu and Odisha. It is conjectured that these deposits will result in higher emissions of radon isotopes ((222)Rn and (220)Rn) and their daughter products as compared to Normal Background Radiation Areas (NBRAs).

Prognostic significance of genotyping Helicobacter pylori infection in patients in younger age groups with gastric cancer.

Background: Malignant tumours of the stomach are common, but the incidence of stomach cancer varies from country to country, probably a result of genetic, epigenetic and environmental factors. Stomach cancer often occurs in older people whose stomachs produce only small quantities of acid. Although infection with Helicobacter pylori has been proven beyond doubt in the aetiopathogenesis of various gastric disorders, not much is known about the genotypes of H pylori infection in early-onset gastric cancer.

Isolation and characterization of enteroaggregative Escherichia coli (EAggEC) by genotypic and phenotypic markers, isolated from diarrheal children in Congo.

OBJECTIVE: To determine the prevalence of enteroaggregative Escherichia coli (EAggEC) in African diarrheal children in Lwiro, Congo, to characterize EAggEC isolates by possible genotypic and phenotypic markers, and to evaluate the EAggEC probe pCVD432 in identifying EAggEC. METHODS: The Hep-2 cell adhesion assay and colony-blot hybridization assays were carried out for the identification of EAggEC. O:H serotyping, biotyping, antibiogram and plasmid-profile analysis were done.

Molecular epidemiological study of nosocomial Enterobacter aerogenes isolates in a Belgian hospital.

In 1995, the rate of isolation of Enterobacter aerogenes in the Saint-Pierre University Hospital in Brussels, Belgium, was higher than that in the preceding years. A total of 45 nosocomial E. aerogenes strains were collected from 33 patients of different units during that year, and they were isolated from 19 respiratory specimens, 13 pus specimens, 7 blood specimens, 4 urinary specimens, 1 catheter specimen, and 1 heparin vial.
