The objective of this study was to assess insecticide resistance in anopheline mosquito populations in agroecosystems with high and low insecticide use in a malaria endemic area in Chiang Mai province in northern Thailand. Anopheline mosquitoes were collected in May and June 2004 from two locations with different agricultural insecticide intensity (HIGH and LOW), but similar in vector control s...

BACKGROUND Horizontal transfer of insecticide occurs when insects contact or ingest an insecticide, return to an aggregation or a nest, and transfer the insecticide to other conspecific insects through contact. This phenomenon has been reported in a number of insects including social insects, however it has not been reported in bed bugs. Since horizontal transfer can facilitate the spread of in...

High-power laser diode arrays are used for a variety of space-based laser programs as an energy source for diode-pumped solid-state lasers. Specifically, 1064 nm Nd:YAG lasers require laser diode arrays emitting at a wavelength of 808 nm that operate at quasi-cw peak powers of 100 Watts per bar. Reliability and performance data is needed for these components; particularly for operation in a sat...

We present the observation of a new intermediate redshift damped Lyα absorption system candidate, discovered in the course of a spectroscopic follow-up for identifying the sources detected in a 150Å-wide bandpass UV-imaging survey at 2000Å. The system displays very strong Mg ii and Fe ii lines and a high Fe ii/Mg ii ratio, which, following photoionization models, indicates a very high neutral h...

Eleven subjects with non-paralytic and 10 with paralytic kyphoscoliosis and nine normal control subjects were studied during sleep. The Cobb angle of those with kyphoscoliosis varied from 600 to 1400 (median 100°) and the vital capacity varied from 17% to 56% (median 28%) of the value predicted on the basis of span. Recordings made during sleep included expired carbon dioxide tension at the nos...

Zr-containing UiO-66 and MOF-808 are evaluated for converting levulinic acid (LA) into γ-valerolactone (GVL) through various routes: (i) Step-wise esterification of LA to n-butyl levulinate (nBuL) Meerwein-Ponndorf-Verley (MPV) reduction GVL; (ii) One-pot two-steps with n-butanol followed by MPV sec-butanol; (iii) direct conversion GVL a tandem reaction. Selection this multistep complex reactio...

Molecularly defined organometallic rhodium phosphine complexes were efficiently heterogenized within a MOF structure without affecting neither their molecular nature nor catalytic behavior. Phosphine-functionalized MOF-808 served as solid ligand in series of eight catalysts. These MOF-heterogenized catalysts showed activity up to 2100 h–1 for ethylene hydroformylation toward propionaldehyde the...

We prove two supercongruences for specific truncated hypergeometric series. These include a uniparametric extension of supercongruence that was recently established by Long and Ramakrishna [Adv. Math. 290 (2016), pp. 773–808]. Our proofs involve special instances various identities including Whipple’s transformation the Karlsson–Minton summation.

in order to determine the genetics of barley lines for freezing resistance based on crown survival percentage an experiment was carried out as a split plot design on the basis of randomized complete blocks with two replications. forty barley lines were assigned in subplots and five freezing temperatures (-8, -11, -13, -15 and -17 ˚с) were allocated in main plots. the results showed significant ...
