Isoprene has received widespread attention in breath research because of its potential to serve as a sensitive and non-invasive biomarker for the detection monitoring several metabolic effects. To date, activity on isoprene focused mass spectrometry-based measurement techniques, which are not portable require skilled operators. Here, we show, first time our knowledge, selective exhaled (148 sam...

Wireless sensor networks (WSNs) have many applications in the areas of commercial, military and environmental requirements. Regarding the deployment of low cost sensor nodes with restricted energy resources, these networks face a lot of security challenges. A basic approach for preparing a secure wireless communication in WSNs, is to propose an efficient cryptographic key management protocol be...

We present interferometric observations with∼3.5′′ resolution of the 2k → 1k methanol lines towards the methanol masers in the DR21/DR21(OH) complex. These transitions are not masing and hence our measurements can be used to place limits on the methanol mass associated with the maser spots. We do not find in general good correlation between the peaks of “non-maser” methanol emission and the pos...

A 22-year-old male presented with acute onset vomiting, diarrhea, abdominal pain and altered sensorium. He had a history of acute alcohol intake (locally made with solvent) a day prior to the presentation. Biochemical investigations revealed severe metabolic acidosis. Diagnosis of methanol poisoning was made on the basis of history and biochemical abnormality. Magnetic resonance imaging (MRI) d...

a sodium dodecyl sulfate modified carbon paste electrode (sds/cpe) was developed in this work based on the surface modification method. the modified electrode was prepared by immersing sds/cpe in a nickel nitrate solution. this electrode showed a strong accumulation ability toward nickel ions. then modified electrode was conditioned by potential recycling in a potential range of 0.2–0.8 v (vs. ...

feasibility of methanolic wastes treatment containing chlorophenol in experimental uasb reactors i.e. r-i and r-ii working side by side constantly for a couple of almost 32 weeks were studied. uasb reactor r-i was initiated by utilizing the digested sludge alone, whereas, the uasb reactor r-ii was startedup by adding an activated carbon of an effective size 1.5-2.5mm to the digested sludge with...

background: world health organization (who) reported continuous increase of alcohol consumption in southeast asian region. on social and religious ground, open alcohol consumption is banned in bangladesh though incidence of acute methanol intoxication is seriously increasing. unfortunately, apart from who report (2004) there is no available epidemiological and clinical data in bangladesh. this ...

in order to gain a better understanding of the chemistry of methanl-to-hydro-carbon conversion, it is necessary to determine the nature of the primary reaction products. experiments carried out in this work on h-zsm-11, using a continuous flow reactor linked to an on-line gas chromatograph demonstrated that ethylene and methane are the primary reaction products. the results obtained using solid...
