Solutions exchange systems are responsible for the timing of drug application on patch clamp experiments. There are two basic strategies for generating a solution exchange. When slow exchanges are bearable, it is easier to perform the exchange inside the tubing system upstream of the exit port. On the other hand, fast, reproducible, exchanges are usually performed downstream of the exit port. A...

The goal of the present work was to develop minimally invasive imaging techniques to monitor local regeneration of peripheral nerves and to determine the extent of return to function of brain cortical regions associated with that nerve. The sciatic nerve crush model was applied to Sprague-Dawley rats and conventional histological staining for myelin, axons and cell architecture was carried out,...

We investigated the influence of the Stiles-Crawford peak location on visual acuity, contrast sensitivity and phase transfer with 6 mm diameter pupils in two subjects. Apodising filters were used to move the peak. One subject (SM) had her natural peak 0.9 mm below pupil centre, and visual performance was measured for both this peak position and when the peak was moved to the same distance above...

An analytical solution of macrodispersivity was derived for the adsorbing solute transport in physically and chemically heterogeneous unsaturated soils under the condition of gravity-dominated flow. The unsaturated hydraulic conductivity and water content were treated as spatial random functions. The chemical adsorption was described by a linear equilibrium isotherm, and the adsorption coeffici...

Pigeons (Columba livia) searched for food hidden in the center of a square enclosure. On occasional tests without food, the enclosure was (a) unchanged from training (control tests), (b) moved to different corners of the testing room (corner tests), or (c) doubled in size (expansion tests). The birds showed localized search in the center of the enclosure on control and corner tests. On expansio...

This research used geocoded data from 10 waves (2000 – 2009) of the German Socio-economic Panel Study to investigate the spatial distances of young adults’ initial move-outs (N = 1,986). Linear regression models predicted moving distances by factors at individual, family, household, and community level. Overall, home leavers moved across strikingly small distances with a median value of less th...

Higher populations of Meloidogyne incognita larvae and Pratylenchus penetrans were recovered from soil treated with carbofuran 10 and 15 days after treatment, respectively, than were recovered from untreated control soil. The number of P. penetrans, however, was lower 50 days after treatment, and symptoms developed only occasionally on the root systems of host plants. Populations of Tylenchorhy...

In this article a survey on algorithms used for recovery of failure nodes in wireless sensor network has presented. Node recovery is a technique used to recover the failure of most used active nodes in WSN, when it becomes crucial to repair these nodes from failure and also from the situation where some part of covering area gets out of control and sight of the networks. The information flow ge...
