The natural environment affects the construction of desert highways. Conversely, highway construction affects the natural environment and puts the ecological environment at a disadvantage. To satisfy the variety and hierarchy of desert highway construction and discover the spatio-temporal distribution of the natural environment and its effect on highway construction engineering, an assessment o...

Ascophyllum nodosum is the most important commercial seaweed. Seaweeds have been applied as soil conditioners in improving plant growth and development in agricultural crops. In current study and for the first time, extracts of brown seaweed A. nodosum improved the growth of Robinia pseudoacasia L., an ornamental tree. This research investigated the effect of cultivation beds (sand, perlite, co...

Effects of different levels of compost application on the amounts and percentage distribution of organic N forms in whole soils and particle size fractions were investigated. Soil samples were collected from three plots: a) F, only chemical fertilizers; b) F + LC, chemical fertilizers plus low level of compost; (c) F + HC, chemical fertilizers plus high level of compost. Each soil sample was di...

The role of spatial distribution of porous medium patchwise chemical (charge) heterogeneity in colloid transport in packed bed columns is investigated. Colloid transport experiments with carboxyl latex particles flowing through columns packed with chemically heterogeneous sand grains were carried out. Patchwise chemical heterogeneity was introduced to the granular porous medium by modifying the...

The NW-trending Denizli basin of the SW Turkey is one of the neotectonic grabens in the Aegean extensional province. It is bounded by normal faults on both southern and northern margins. The basin is filled by Neogene and Quaternary terrestrial deposits. Late Miocene- Late Pliocene aged Kolankaya formation crops out along the NW trending Karakova uplift in the Denizli basin. It is a typical flu...

OBJECTIVES The International Agency for Research on Cancer (IARC) and Japan Society for Occupational Health (JSOH) classified wood dust as a human carcinogen. Former studies have suggested that sanding with a portable sander is one of the processes that are liable to cause highest exposure to wood dust. However, the wood dust by sanding operation has not been investigated sufficiently. In this ...

Phlebotomine sand flies are distributed across nearly all faunal regions of the world, represented by over 800 species, of which many are important vectors of human pathogens. Brazil is currently faced with the expansion and urbanization of leishmaniases, with an increase in the numbers of human cases and seropositive dogs in various medium-sized to large cities. The objective of the current st...

Larval and adult Tribolium confusum were tested in flour and sand substrates at various relative humidities, ranging from 10% to 90%. Both life stages preferred a flour environment of from 10% to 50% relative humidity. In sand, however, the insects selected more humid environments. Investigations of survival in sand, flour, and air environments indicated that two factors may be operating in the...
