A sweep net with a flexible plastic frame was compared to a dipper for sampling efficacy for Aedes aegypti larvae in different-sized tires. When known numbers of mosquito larvae were introduced into tires, from 2 to 6.8 times more larvae were recovered by sweeping than by dipping. Sediment in the tires significantly reduced the recovery of larvae by both methods. Sampling efficacy was affected ...

Blood Pressure (BP) dipping is defined as the difference in BP from average waking to sleeping measurement. BP follows normal circadian rhythm of dipping at night at about 10-15% as compared to the day. Night time dipping is further divided into 4 types, reverse dipper (<0%), non-dipper (0-10%), dipper (10-20%) and extreme dipper (>20%). The dip is thought to be affected by an inability to excr...

BACKGROUND Higher nighttime blood pressure (BP) and the loss of nocturnal dipping of BP are associated with an increased risk for cardiovascular events. However, the determinants of the loss of nocturnal BP dipping are only beginning to be understood. We investigated whether different indicators of physical activity were associated with the loss of nocturnal dipping of BP. METHODS We conducte...

Blood pressure (BP) normally decreases during the night. Absence of this phenomenon (nondipping) is associated with increased cardiovascular risk. Altered autonomic and endocrine circadian rhythms are suspected to play a role. Patients with peripheral autonomic failure offer a unique opportunity to study this phenomenon, because approximately 50% develop supine hypertension despite very low aut...

[1] Flat or shallow subduction is a relatively widespread global occurrence, but the dynamics remain poorly understood. In particular, the interaction between flat slabs and the surrounding mantle flow has yet to be studied in detail. Here we present measurements of seismic anisotropy to investigate mantle flow beneath the Peruvian flat-slab segment, the largest present-day region of flat subdu...

The exploratory behaviour of laboratory rodents is of interest within a number of areas of behavioural pharmacology. However, how best to measure exploratory behaviour in rodents remains a contentious issue. Many unconditioned tests, such as the open field, potentially confound general locomotor activity with exploration. The hole-board apparatus appears to avoid this confound, as head-dipping ...

The effectiveness of calcium hypochlorite on inactivation of Escherichia coli inoculated on fresh produce was investigated. Different exposure times and concentrations of chlorine were studied. Dipping was not effective at eliminating E. coli populations although it significantly reduced the E. coli counts compared with inoculated, undipped lettuce. Dipping inoculated cos lettuce leaves into hy...

We develop a tractable model of competition among motivated MFIs. We find that equilibria may or may not involve double-dipping (and consequently default), with there being double-dipping whenever the MFIs are very profit-oriented. Moreover, in an equilibrium with double-dipping, borrowers who double-dip are actually worse off compared to those who do not. Further, for intermediate levels of mo...
