Soil complexity and environmental heterogeneity may be viewed as a consequence of deterministic chaotic dynamics and therefore highly irregular patterns with so-called multifractal behavior should be common. This approach introduces a distinct viewpoint as compared with fractal models for soil surface roughness based on fractional Brownian motion. It suggests that it would be useful to move awa...

In GdFeCo/Ir/GdFeCo heterostructures with amorphous GdFeCo layers, three critical points were found in the temperature dependences of magnetization. neighborhood 100 K, compensation for magnetizations Gd and FeCo sublattices is observed, which form a magnetization minimum does not depend on magnetic field. As decreases, sharp stepwise transition corresponds to switching mutual magnetization’s o...

This paper introduces and discusses the consistency and effectiveness of an inexpensive modification of Pollard transects for assessing the diversity and abundance of tropical butterfly communities in two national parks in Rio de Janeiro, Brazil. To measure butterfly abundance, students walked simultaneous timed transects at the interface of forest and cleared areas. They either counted the num...

Smile line is one of the most important element of the smile esthetics. In an attractive smile, the maxillary anterior incisal curve is parallel to the lower lip. With the changes in face, lips and teeth muscles, which are caused by aging, this element (smile line) also changes. Aging causes smile line to move from its parallel position and in complete smile, formulate different shapes relative...

Monitoring fish assemblages is needed to assess whether Marine Protected Areas (MPAs) are meeting their conservation and fisheries management goals, as it allows one to track the progress of recovery of exploited species and associated communities. Underwater Visual Census techniques (UVC) are used to monitor fish assemblages in MPAs. UVCs should be adapted to fish abundance, body-size and beha...

Mobile acoustic surveys attempt to map and count aquatic organisms without biasing abundance estimates. Horizontal and vertical movements by target species may influence density measurements and net samples during acoustic surveys. To investigate the influence of fish movement on density data, we compared temporal and spatial variability of walleye pollock (Theragra chalcogramma) in three sets ...

This article describes design, operation and experimental testing of a mechanical DC CB (Circuit Breaker) with parallel capacitors. The topology resembles hybrid but there are possible advantages in the costs since main semiconductor valve is replaced capacitors, performance this breaker inserts counter voltage earlier. A detailed PSCAD model employed to support design analyse operating princip...

Elevated blood flow (reactive hyperemia) is seen in many organs after a period of blood flow stoppage. This hyperemia is often considered to be due in part to a shift to anaerobic metabolism during tissue hypoxia. The aim of our study was to test this hypothesis in skeletal muscle. For this purpose we measured NADH fluorescence at localized tissue areas in cat sartorius muscle during and after ...

Distance sampling is extensively used for estimating animal density or abundance. Conventional methods assume that location of line or point transects is random with respect to the animal population, yet transects are often placed along linear features such as roads, rivers or shorelines that do not randomly sample the study region, resulting in biased estimates of abundance. If it is possible ...
