Mountains are centres of global biodiversity, endemism and threatened species. Elevational gradients present opportunities for species currently living near their upper thermal limits to track cooler temperatures upslope in warming climates, but only if changes in precipitation are sufficiently in step with temperature. We model local population extirpation risk for a range of temperature and p...

In this paper, we present a technique that first align the page (Skew Correction) after that removing the pre-printed rule lines in handwritten Devanagari document images. This paper is first approach toward the rule line removal from Devanagari Script. In survey we found a lot of work has done on English, Greek, Arabic etc. language which has different script and style to write. We use common ...

One of the newer scales of suicide risk devised by Plutchik and colleagues was tested to see if it could discriminate between levels of suicide ideation and suicide attempts. A sample of 80 subjects were placed into various categories of suicide risk on the basis of a psychiatric examination. Results showed that the full scale did not adequately discriminate among groups. An explantation of the...

Surgical-site infection is a preventable adverse event. Implementation of good practices for correct surgical-site preparation can contribute to lessen this safety problem. The objective of this study was to describe the presence and quality of protocols on surgical-site preparation in the Murcia (Spain) regional network of public hospitals. The indicator "existence of protocol for surgical-sit...

this study evaluates the effectiveness of adsorption process by granular activated carbon (gac) compared with a novel formulation of coagulation - flocculation process for dye removal from textile wastewater. in this regard, acidic, reactive, disperse and direct red dye are used to prepare the synthetic dye. dominant wave length for each dye is determined by spectrophotometeric method. using ga...

an experiment involving erosion simulation was conducted at the soil and water con-servation research center of the university of tehran. a split-factorial plot with four replications was designed. five soil desurfacing treatments of blank, 5, 10, 15, and 20 cm of soil surface removal (e0, e5, e10, e15, and e20) were carried out, respectively. fertilizer treatments were 0, 65, and 130 kg ha-1 o...

this paper investigates the removal of iron and zinc from aqueous solution with dairy wastewaterin three different biomasses such as lactobacillus delbrueckii ssp bulgaricus (lb-12), streptococcus thermophillus(stm-7) and a combination of both this bacteria culture (yc-380) and the optimization of removal efficiencyusing minitab program. a full 23 factorial design of experiments was applied to ...

manganese is one of the significant raw materials for various industries and most difficult element to remove from water because of its high solubility. the treatment of mn (ii) contained wastewater is stringent for environmental preservations. in the present study adsorption of mn2+ on zero-valent iron nanoparticles synthesized by chemical reduction process and modified with phosphate coating ...
