The traditional indoor spraying technique to control Anopheles albimanus mosquitos was compared with a selective method that targets their preferred resting sites in coastal villages of southern Mexico. We also determined whether mosquitos changed their preferred resting sites following insecticide applications. In the selective spraying approach, two 1-m wide horizontal swaths of bendiocarb in...

A basic system dynamics model for collective irrigation management is proposed, which is aimed at improving the understanding of dynamic processes in collective irrigation systems. In particular, the problem of free-riding on water in irrigation systems is addressed. A feedback system is introduced, which builds on the concept of a critical mass and integrates a number of influence factors that...

abstract we reported and analyzed an unusual case of npc (nasopharyngeal carcinoma) where the patient had initial clinical features of cavernous sinus involvement followed by trigeminal neuralgia and middle ear dysfunction. in the present case, the initial involvement of the cavernous sinus resulted in the left sided third nerve involvement. later on, the extension of the tumor in and around th...

tomato (solanum lycopersicum l.) is one of the most important vegetable plants in the world. it originated in western south america, and domestication is thought to have occurred in central america. in order to study the effect of polyethylene sheet as mulch on water requirement and yield of tomato, an experiment was carried out as factorial layout based on a randomized complete block design wi...

Aim: The aim of this study was to evaluate the effectiveness of two instrumentation and irrigant techniques in smear-layer removal from root canals. Methodology: Thirty single-rooted teeth were randomly divided into two groups. Group 1 (continuous irrigation) was prepared using Selfadjusting file, and group 2 (manual irrigation; conventional needle irrigation) was prepared using with ProTaper f...

In this paper, we study cost efficient multi-copy spraying algorithm for routing in Delay Tolerant Networks (DTN) in which source-to-destination path does not exist most of the time. We present a novel idea and the corresponding algorithm for achieving the average minimum cost of packet transmission while maintaining the desired delivery rate by the given deadline. The number of message copies ...
