Agrochemical pesticide production, trade, and hazard: Narrowing the information gap in Colombia

on the relationship between different discourse markers and information-gap and reasoning-gap tasks, and the effectiveness of input enhancement type of instruction on students acquisition of discourse markers.

abstract tasks nowadays are at the center of attention in sla research. task types is one of the critical issues in this regard, their effectiveness and suitability to any particular context, their characteristics and the result they yield are among some of these issues. on the other hand, discourse markers (dms) have been very much investigated and their effectiveness in conveying the meaning...

Narrowing the gap.

Since 1981 AIDS has illuminated, like a roving searchlight, a series of ethical questions, which extend far beyond the apparently narrow limits of one disease. It has revealed, one by one, human attitudes and behaviours that were previously unquestioned, or unobserved based on unidentified but shaky pre-suppositions. This commentary oVers two contrasting perspectives on the problems facing deve...

Narrowing the Nutrition Gap:

Quantitative estimation of pesticide-likeness for agrochemical discovery

BACKGROUND The design of chemical libraries, an early step in agrochemical discovery programs, is frequently addressed by means of qualitative physicochemical and/or topological rule-based methods. The aim of this study is to develop quantitative estimates of herbicide- (QEH), insecticide- (QEI), fungicide- (QEF), and, finally, pesticide-likeness (QEP). In the assessment of these definitions, w...

Identification and assessment of hazard in the Refractory Brick Production Company of Gonabad, Iran, using the hazard and operability technique

  Background: In the refractory brick manufacturing industry, because of the high risks associated with the level of dust in the factory environment and thermal stress, a precise identification of industrial hazards is required as a part of safety analysis. The aim of this study was to introduce a preventive approach to risk identification and assessment in the refractory brick production ...
