Abstract This study aimed to estimate arsenic (As) and iron (Fe) content in tubewell water ( n = 58) primary educational institutions subsequently assess the health risks school-going children. Results described that As concentration ranged between 0.002 0.994 mg L −1 with an average value of 0.044 ; which exceeded World Health Organization (WHO) provisional guideline 0.01 . Similarly, Fe varie...

We report the discovery of a new pulsating DA white dwarf, or ZZ Ceti, from the list of the Palomar-Green survey, rediscovered in the ongoing Hamburg Quasar survey (HQS). PG1541+650 is one of the ZZ Ceti candidates listed in the analysis of 80 DA white dwarfs from the HQS. With an effective temperature of 12000 K, for a surface gravity logg=7.79, it lies in the ZZ Ceti instability strip. It is ...

Against the background of evidence-based treatments for schizophrenia, nowadays the implementation of specific cognitive and behavioral interventions becomes more important in the standard care of these patients. Over the past 25 years, research groups in 9 countries have carried out 30 independent evaluations of Integrated Psychological Therapy (IPT), a group program that combines neurocogniti...

In wireless networks, terminating handoff calls is generally more objectionable than blocking new calls. The Guard Channel Scheme (GCS) and Handoff Queueing Scheme (HQS) are the popular and practical strategies to prioritize handoff calls. A key issue when giving handoff calls the higher priority is how to achieve a tradeoff among the handoff call blocking probability, new call blocking probabi...

Yangtze finless porpoise (Neophocaena phocaenoides asiaeorientalis), a protected endangered species, is the sole freshwater subspecies of finless porpoise, living only in the middle and lower reaches of the Yangtze River, China, and its appended lakes. Its population has decreased sharply to 1,400 because of human activities, including environmental contamination. In the present study, polychlo...

Concentrations of polybrominated diphenyl ethers (PBDEs), and organochlorine pesticides (OCPs; DDTs, HCHs, CHLs, and HCB) were measured in human breast milk samples collected across Massachusetts, USA, in 2004. Seventeen PBDE congeners were found in the samples, ranging in concentration from 0.06 to 1910 ng g À1 lipid wt. 0 ,6-pentaBDE) were the major congeners detected in breast milk samples. ...

Wheat (Triticum aestivum L.) flour consumption may be a major source of human metal intake, especially when wheat is cultivated in metal-contaminated soils. This work investigated Cd, Cu, Pb, and Zn distribution whole flour, bran grown an area polluted by Pb smelting. product heavy concentrations were analyzed, the (non)carcinogenic risks assessed. Mean 0.38, 3.83, 0.48, 29.3 mg kg–1, respectiv...
