background: leishmaniasis is an obligate intercellular protozoon that affects animals and human. it has zoonosis and/or anthroponosis transmission. human and veterinary medicine, environmental science and wildlife conservation special­ists have many commonalities in case of visceral leishmaniasis. still the above disciplines respond against leishmaniasis in a separate way.   the aim of this re­...

Dispersal is a biological process performed in three stages: emigration, transfer and immigration. Intra-specific variation on dispersal behavior, such as sex-bias, is very common in nature, particularly in birds and mammals. However, dispersal is difficult to measure in the field and many hypotheses concerning the causes of sex-biased dispersal remain without empirical confirmation. An importa...

The elicitation of a positive patch test reaction in a given individual depends upon the dose of the sensitizer applied, the patch test technique and the occlusion time. The dose is determined by the concentration and volume/amount of test preparation applied. If the same amount/volume of a test preparation is applied all the time with the same test technique (same area of skin) and occlusion t...

This paper describes a method to approach area-patch problems in model generalization using fuzzy set theory. The area patch problem identifies problems in generalizing areas (polygons) with the same semantics (feature code) but varying geometry and spatial distribution. Area-patch generalization can be understood as a pattern recognition problem with a variety of viable solutions, constrained ...

A wideband improvement for hybrid plasmonic fractal patch nanoantenna is presented use in intra/inter chip optical interconnects. The suggested antenna covering a part of U-band (1625-1675), L-band (1565-1625nm), C-band (1530-¬1565nm), S-band (1460-1530nm), E-band (1360-1460nm) and most O-band (1260-1360nm) communication bands. proposed has promising future inter intra communications to elimina...

Plants may induce small-scale heterogeneity in soil nutrients, forming fertile islands. However, this process may depend on plant spices, plant developmental stages and habitat conditions. Vegetation cover in arid and semi-arid regions is mostly in the form of plant patches and bare soil of inter-patch areas, this form of vegetation cover can be useful to study plants impact on soil to get appl...

BACKGROUND In group-living animals, social interactions and their effects on other life activities such as foraging are commonly determined by discrimination among group members. Accordingly, many group-living species evolved sophisticated social recognition abilities such as the ability to recognize familiar individuals, i.e. individuals encountered before. Social familiarity may affect within...
