Every minute, 1·1 million litres of human excrement joins the river Ganges. It is a staggering statistic but hardly surprising since some 627 million Indians practice open defecation, roughly half the country’s population, and more than half of the estimated 1 billion people around the world who defecate openly. Most of these people live in ten countries in Asia and sub-Saharan Africa. Indonesi...

Introduction: The head scatter factor (Sc) is one of the important parameters for monitor unit (MU) calculation. There are multiple factors that impact the Sc values, such as, head structures, back scattering in to dose monitoring chambers, wedges and so on. This study aimed to investigate the variations of SC with different build-up cap materials, wall thickness, Source to ...

There are many practical situations where a finite mass of a buoyant gas may become suddenly exposed to atmospheric air at a negligible pressure difference within vertical chambers or vessels that are either fully or partially open. The consideration of such situations when a fuel or toxic gas is released is of immense practical importance especially in relation to developing measures for prote...

concentration of co2 in the atmosphere is likely to increase up to 550 µmol mol-1 by the middle of 21st century. such an increase in the atmospheric co2 would affect plant growth, and as well the productivity of crop plants. a field experiment was conducted with two potato cultivars namely kufri surya and kufri chipsona-3 grown inside open top chambers (otcs) at ambient (385±30 µmol mol-1) vs. ...

In order to improve the energy dissipation of the masonry infilled frame structure while decreasing the stiffening and strengthening effects of the infill panels, a new dry stacked panel (DSP) semi-interlocking masonry (SIM) infill panel has been developed. In this paper, the material properties of DSP and a traditional unreinforced masonry (URM) panel have been evaluated experimentally. A seri...


 The experiment was conducted at experimental farm situated 30◦5’N latitude and about 77◦11’E longitudes, an elevation of 1260 m above mean sea level Department Environmental Science, Dr YS Parmar University Horticulture Forestry Nauni, Solan, Himachal Pradesh during 2014 2015, to study the effect elevated CO2 (eCO2) temperature (eT) on growth, development nutritional indices Spodopterali...

-Two parallel-plate ionization chambers were projected, constructed and evauated for use in high energy electron beams. They were constructed using the two plastic materials recommended for clinical dosimetry protocols, i.e. acrylic and polystyrene. Both chambers have cylindrical shape with entrance windows in aluminized Mylar and they are open to the air. The acrylic chamber has a 2 mm air gap...

Plant height, biomass production, assimilatory functions and chlorophyll accumulation of Panicum maximum and Stylosanthes hamata in intercropping systems was influenced significantly under elevated CO2 (600 +/- 50 ppm) in open top chambers (OTCs). The plant height increased by 32.0 and 49.0% over the control in P. maximum and S. hamata respectively in intercropping system under elevated CO2 ove...

background: in order to deliver the precise dose to the target in radiotherapy, absorbed dose to water at the reference point should be assessed. when the calibration procedure is performed for a reference dosimeter in the 60co beam of a secondary standard dosimetry laboratory (ssdl), the total uncertainty in absorbed dose to water (dw) is estimated to be approximately 1.5%. this study attempts...
