In the Peruvian Amazon, white-sand forests are patchily distributed and restricted to a few localities in the North. Although recent studies have documented patterns of habitat specialization by plants in these unique forests, very few studies of the fauna of these habitats have been conducted. The species composition of the avifauna of the white-sand forests at six localities in the region was...
BACKGROUND Visceral Leishmaniasis (VL) is a life threatening neglected infectious disease in the Indian subcontinent, transmitted by the bite of female sand flies. Estimation of the infectivity in the vector population, collected in different seasons, may be useful to better understanding the transmission dynamics of VL as well as to plan vector control measures. METHODOLOGY We collected sand...
Phlebotomus papatasi sand flies are among the primary vectors of Leishmania major parasites from Morocco to the Indian subcontinent and from southern Europe to central and eastern Africa. Antibody-based immunity to sand fly salivary gland proteins in human populations remains a complex contextual problem that is not yet fully understood. We profiled the immunoreactivities of plasma antibodies t...
This article brings out the improved thought of college admission system reform based on parallel will: College Admission Mode of Multiple Choices Based on Internet,CAMMCBI。We use the absorbing Markov analysis method to establish the student scores and college level sequence model of absorbing Markov chain, analysis CAMMC BI admission mechanism problem from the angle of dynamic. Reform of Colle...
We present a theoretical study on how dynamic radiation force of acoustic waves actuates on absorbing spheres. We consider the radiation force is generated by the difference-frequency component of a bichromatic plane wave in a lossless fluid. We analyze the spectrum of the dynamic radiation force for polymethymethacrylate (lucite) and polyethylene spheres. Results reveal that absorption cause t...
Clematis flammula var. maritima is a woody lianoid plant that grows on coastal sand dunes in the Mediterranean region. Older perennial stems are present as extensive underground axes. These generate surface growth of shorter-lived stems producing monospecific trellises above the surface of the sand. Despite its sand dune habitat and shortage of host support plants, this variety of Clematis show...
Organisms with external fertilization are often sperm limited, and in echinoids, larger eggs have a higher probability of fertilization than smaller eggs. This difference is thought to be a result of the more frequent sperm-egg collisions experienced by larger targets. Here we report how two components of egg target size, the egg cell and jelly coat, contributed to fertilization success in a se...
Abstract Nowadays the waste rubber problems are concerned due to environmental issues, storage, and recycling difficulty. However, base equipment has been widely used protect structures for vibrations - that generated by structure or induced from vicinity area bedrock into notable capability of absorbing energy. In this study, repeated-loading behaviour Sand Rubber Mixture (SRM) investigated re...
