Charcoal production is often accompanied with gaseous and particulate emission into the atmosphere and occupationally exposed workers could be affected. This cross sectional comparative study was carried out to assess the levels of carbon monoxide (CO), carbon dioxide (CO2), sulphur dioxide (SO2), nitrogen dioxide (NO2) and particulate matter (PM2.5) generated during the phases of charcoal prod...

a r t i c l e i n f o Keywords: Signal-to-noise index (SNI) Charcoal analysis Fire history Lake sediment Paleoecology Charcoal peaks in lake-sediment records are commonly used to reconstruct fire histories spanning thousands of years, but quantitative methods for evaluating the suitability of records for peak detection are largely lacking. We present a signal-to-noise index (SNI) that quantifie...

Background Antibiotics are life-saving drugs but severely affect the gut microbiome with short-term consequences including diarrhea and selection of antibiotic-resistant bacteria. Long-term links to allergy and obesity are also suggested. We devised a product, DAV132, and previously showed its ability to deliver a powerful adsorbent, activated charcoal, in the late ileum of human volunteers. ...

The aim of the present study was to investigate the efficiency of the encapsulation-dehydration technique for cryopreservation of Cyrtopodium hastchbachii Pabst seeds. Immature seeds of this species were cryopreserved by an encapsulation-dehydration technique. Seeds of five immature pods, 120 days after pollination, were encapsulated in 3% calcium alginate matrix and pretreated in liquid medium...

T he charcoal production process has been known since the Bronze Age, and was vital to metallurgy until the discovery of the conversion of coal to coke at the beginning of the 18th century. Brazil, now the largest charcoal producer of the world, with more than 12 million metric tons in year 2002, has preserved its charcoal based industries in large part because it has extensive iron deposits an...

A haemoperfusion column containing activated charcoal coated with cellulose acetate was used to treat 7 patients with barbiturate or ethchlorvynol poisoning. Six of the patients showed marked lightening of coma and all showed a significant fall in plasma drug concentration. Plasma drug clearance and platelet loss were similar to those reported for other coated charcoal columns. Cellulose acetat...

Withania somnifera (L.) Dunal is an important ayurvedic medicinal plant known mainly for its rejuvenating properties. In vitro micropropagation or multiplication of Withania somnifera through apical shoot proliferation by using different concentrations of growth regulators in short period. Shoots were induced from the apical meristem of Withania somnifera on Murashige and Skoog (MS) basal media...

Charcoal rot diseases of melon caused by Macrophomina phaseolina is one of the most important diseases of melon occurring in regions with variable climate. Reduction of yield of melon by this disease has been reported up to 100% in some of Garmsar field. Salinity which can cause the important trouble in plant metabolism and nutrition is present in Semnan and Garmsar areas. Melon is susceptible ...

Aconite is a plant with deceptively beautiful flowers that contain deadly cardiotoxin. toxicity presents often fatal ventricular arrhythmias are refractory to conventional antiarrhythmic medications. An electrical storm (ES) an acute cardiac emergency carries high mortality. We report one such case of aconite presenting ES was managed successfully hemodynamic support, overdrive pacing, and char...

Fire history reconstructions are typically based on tree ages and tree-ring fire scars or on charcoal in sedimentary records from lakes or bogs, but rarely on both. In this study of fire history in western Patagonia (47–48 S) in southern South America (SSA) we compared three sedimentary charcoal records collected in bogs with tree-ring firescar data collected at 13 nearby sample sites. We exami...
