Diamond-shaped pheromone-baited traps are used widely in food storage and food processing facilities for monitoring of Plodia interpunctella (Hübner), and here we evaluated to what extent trap captures were affected by 1) vertical placement of traps, 2) deployment of a horizontal landing platform to the diamond-shaped pheromone trap, and 3) placement of traps either freely exposed or along a si...

We have used a large-scale gene trap approach for the isolation and mutation of genes that might play roles in the developing nervous system. After in vitro integration of two different gene trap vectors (pGT1.8geo: Skarnes et al. [1995] Proc. Natl. Acad. Sci. USA 92:6592-6596; IRES beta geo: Chowdhury et al. [1997] Nucleic Acids Res. 25:1531-1536) in mouse embryonic stem (ES) cell lines, we cr...

Reservoir sedimentation has been a global bottle neck in maintaining the design storage capacity of reservoirs. leads to reduction original which affects irrigation, hydropower, flood control, drinking water supply and recreational activities. Introduction mechanized farming without due regard nature environment is aggravating erosion sediment problem. This study discussed analyzed most importa...

Estimating the exposure of individuals to mosquito-borne diseases is a key measure used to evaluate the success of vector control operations. The gold standard is to use human landing catches where mosquitoes are collected off the exposed limbs of human collectors. This is however an unsatisfactory method since it potentially exposes individuals to a range of mosquito-borne diseases. In this st...

In order to increase the lifespan of hydraulic turbines in hydropower plants, it is necessary minimize damages caused by sediment erosion. One solution reduce amount sediments improving design sand trap. present work, effects on trap efficiency installing v-shaped rake structures for flow distribution and rib trapping investigated numerically using SAS–SST turbulence model. The are located diff...

Centers for Disease Control miniature light traps augmented with CO2 provide an effective method of monitoring Culex abundance and may provide a useful supplement to New Jersey light traps used by the California Mosquito Surveillance Program. To assist in standardizing sampling protocols, the present research compared the catch of adult mosquitoes collected using 4 trap designs and 3 CO2 presen...

BACKGROUND High-throughput mutagenesis of the mammalian genome is a powerful means to facilitate analysis of gene function. Gene trapping in embryonic stem cells (ESCs) is the most widely used form of insertional mutagenesis in mammals. However, the rules governing its efficiency are not fully understood, and the effects of vector design on the likelihood of gene-trapping events have not been t...

Optical traps or "tweezers" use high-power, near-infrared laser beams to manipulate and apply forces to biological systems, ranging from individual molecules to cells. Although previous studies have established that optical tweezers induce photodamage in live cells, the effects of trap irradiation have yet to be examined in vitro, at the single-molecule level. In this study, we investigate trap...

The efficiency of ten differently colored modified box traps for collecting tabanids was studied in the Monjoroš Forest in eastern Croatia. A total of 5,436 specimens belonging to 16 species of tabanids grouped into six genera were collected. The genus Tabanus was the most represented with 98% of all collected tabanids. Tabanus bromius comprised 90% of tabanids collected, and was the most abund...

Root and lower stem insects cause significant damage to conifers, vector phytopathogenic fungi, and can predispose trees to bark beetle attacks. The development of effective sampling techniques is an important component in managing these cryptic insects. We tested the effects of trap type and stereochemistry of alpha-pinene, in combination with ethanol, on catches of the root colonizing weevils...
