Lutzomyia (Nyssomyia) whitmani s.l.is the main vector of cutaneous leishmaniasis in state of Mato Grosso, but little is known about environmental determinants of its spatial distribution on a regional scale. Entomologic surveys of this sand fly species, conducted between 1996 and 2001 in 41 state municipalities, were used to investigate the relationships between environmental factors and the pr...
One of the most important issues in water supply for agriculture or drinking is sediment control.Sedimentation in water conveyance channels reduces transmission efficiency. this study evaluated theefficiency of settling basin of Kamandan intake that is located in the village of Aligoodarz in Lorestanprovince. At first sample from water and sediment in inlet and outlet of settling basin in diffe...
On May 18, 2022, a Heniochus intermedius (Steindachner, 1893) individual with total length of 140 mm and weight 58.4 g was caught by trap at depth 14 meters, mixed bottom sand stones, in front the beach Banias (N: 35) ° 7. 0.5' 17', E: 35° 54' 14.73). In this work, we document first record Red Sea species (Lesbesian immigrant), 1893), Syrian coast, seventh entire Mediterranean. As result, numbe...
Sophora tomentosa is a pantropical legume species with potential for recovery of areas degraded by salinization, and for stabilization of sand dunes. However, few studies on this species have been carried out, and none regarding its symbiotic relationship with beneficial soil microorganisms. Therefore, this study aimed to evaluate the diversity of nitrogen-fixing bacteria isolated from nodules ...
One of the most vital problems in the storage and utilization of surface waters for drinking, flood control, hydropower, and agricultural purposes is that of sedimentation in reservoirs and subsequent decline of dam lifetime. The useful lifetime of a dam is defined as the time necessary for approximately 80% of the volume of its initial capacity to be filled by sediments washed in by water. It ...
Extracts of female sex pheromone glands of the sand Salix carpenterworm moth, Holcocerus arenicola, a serious pest of desert thicket, were analyzed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). Based on comparison of retention times and mass spectra of synthetic standards, four compounds were identified as cis-7-tetradecen-1-ol (Z7-14:OH), cis-5-tetradecen-1-yl ac...
Background and aims: Needle trap micro-sampler, with all advantages of microextraction techniques such as solid phase microextraction, owing to the ease of use and becoming a powerful method for air pollution monitoring. In this study, the performance of needle trap micro-sampler device with silica composite of carbon nanotubes, prepared using sol-gel technique, was investigated for health moni...
In this study we tested to what extent grain count data from a laser particle counter, when enriched with granulometric data, can lead accurate measurements of aeolian sediment fluxes in the field. Field experiments were conducted at Koksijde beach (Belgium) vertical array five Wenglor fork sensors and co-located vertically stacked mesh sand traps. Sand collected traps was used both obtain refe...
The objective of this study was to determine the structure, diversity, composition and drivers AMF communities in succession areas Atlantic Forest. Soil root samples were collected three natural ecosystems (mature rainforests, early late secondary forests) with on each ecosystem. In total, 38 taxa identified field more trap cultures a greater richness Acaulospora Glomus. Based estimator, 70% sp...
The efficiency of different types of traps for catching of the Caspian Sea crayfish, Astacus leptodactylus eichwaldi, was investigated from Mar. 2002 to Feb. 2003. Totally 56 traps of four most commonly used types, "Rectangular trap", "Round trap", "Opera house trap" in two colors of "black" and "blue", and "Fathoms plus" only in black...
