The response of Michigan male obliquebanded leafroller, Choristoneura rosaceana, moths to females from three different geographical regions was studied in replicated field trials during 1999. Our goal was to determine the optimal pheromone blend for monitoring the phenology and abundance of this insect in Michigan apples. Traps were baited with either a rubber septum loaded with synthetic phero...

Abstract: Airports have become crucial for connecting business travelers with the global economy. The 2009 opening of rail rapid transit in Richmond, BC Canada is a natural experiment that enables us to identify how improved access to Vancouver International Airport may be capitalized into commercial real estate prices. Few known airport access benefits studies focus on commercial property valu...

Wheezing is one of the most frequent complaints that lead to the use of medical resources in younger children. Generally, wheezing is caused by bronchiolitis and resolves spontaneously without recurrence, but sometimes, wheezing can progress into asthma. Early data on the natural history of childhood wheezing was mostly obtained from retrospective reviews of medical records or from questionnair...

Here we present the one-dimensional (29)Si and (27)Al MAS NMR and two-dimensional (27)Al MQMAS and DQF-STMAS NMR spectra of the monovalent (Na(+), K(+), Rb(+), Cs(+) and NH4(+)) and divalent (Ca(2+), Sr(2+) and Ba(2+)) cation forms of the natural zeolite natrolite (framework type NAT) with complete Si-Al ordering over the crystallographically distinct tetrahedral sites and with the same hydrati...

Natural transformation can lead to exchange of DNA between taxonomically diverse bacteria. In the case of chromosomal DNA, homology-based recombination with the recipient genome is usually necessary for heritable stability. In our recent study, we have shown that natural transformation can promote the transfer of transposons, IS elements, and integrons and gene cassettes, largely independent of...

Campylobacter are known to cause acute bacterial gastroenteritis in humans. Poultry products have been implicated as a significant source of these infections. Six experiments were performed to determine whether Campylobacter could be isolated naturally from the primary and secondary lymphoid organs, liver/gallbladder, and ceca of commercial broiler breeder hens. Broiler breeder hens were acquir...

The procedure for the reliable determination of Be in natural waters by ETAAS was elaborated. Various modifiers (EDTA, Ca(NO3)2, Mg(NO3)2, Pd(NO3)2 and the mixture of Pd(NO3)2 and Mg(NO3)2) for the determination of beryllium was examined. The applicability of the selected Mg(NO3)2 as the appropriate and generally used modifier for the determination of Be in the different types of natural waters...

Murine and human T lymphocytes bear on their surface a receptor that confers on them the ability to attach to a variety of target cells from the same species, derived in vivo and in vitro. Thymocytes and activated T cells attached readily to target cells, while blood T lymphocytes were able to do so only after the removal of sialic acid from either their cell membrane or that of the target cell...

The glycine amidinotransferase gene (GATM) plays a vital role in energy metabolism in muscle tissues and is associated with multiple clinically important phenotypes. However, the genetic diversity of the GATM gene remains poorly understood within and between human populations. Here we analyzed the 1,000 Genomes Project data through population genetics approaches and observed significant genetic...
