Convective clouds are characterized by strong updrafts, enhanced transport of heat and moisture in the upper layers and rainfall processes which are activated in very limited time interval and space and with a variable intensities. The cloud seeding for rain enhancment of such clouds is a big challenge and common practice in many areas over the world for more than 50 years. There is a strong sc...

rapeseed as one the most crops is the basic needs of human feeding in order to produce oil. a field experiment was conducted to study the effects of different tillage system, seeding method and rates on yield and its components, as well as, seed oil percentage of rapeseed (brassica napus l. cv. hyola-401) during 2011-12 growing season at rice research institute of iran-department of mazandaran ...

A silver iodide (AgI) cloud-seeding parameterization has been implemented into the Thompson microphysics scheme of the Weather Research and Forecasting model to investigate glaciogenic cloudseeding effects. The sensitivity of the parameterization to meteorological conditions, cloud properties, and seeding rates was examined by simulating two-dimensional idealized moist flow over a bell-shaped m...

Uncertainty arises in all stages of the visualization pipeline. However, the majority of flow visualization applications convey no uncertainty information to the user. In tools where uncertainty is conveyed, the focus is generally on data, such as error that stems from numerical methods used to generate a simulation or on uncertainty associated with mapping visualization primitives to data. Our...

An attempt has been made quantitatively to assess the prospects for modifying warm fogs by seeding them with condensation nuclei. This has been done by calculating the time-dependent changes in the sizes and concentrations of fog droplets that are predicted by the ordinary equations of diffusion of water vapor to and from the surface of droplets. Their size, molality, and ambient water-vapor de...

Durable hematopoietic stem cell engraftment requires efficient homing to and seeding in the recipient bone marrow. Dissection of cellular and molecular mechanisms by retrospective analysis of functional engraftment studies imposes severe limitations on the understanding of the early stages of this process. We have established an experimental approach for in vivo functional imaging of labeled ce...

The supply of oxygen to proliferating cells within a scaffold is a key factor for the successful building of new tissue in soft tissue engineering applications. A recent in vivo model, where an arteriovenous loop is placed in a scaffold, allows a vascularising network to form within a scaffold, establishing an oxygen source within, rather than external, to the scaffold. A one-dimensional model ...

Statement of Purpose: This study was focused on a collagen/cell mixture seeding method to improve the adhesion and proliferation of vascular smooth muscle cells (SMCs) in tubular porous scaffolds for vascular grafts application. Recently, poly(L-lactide-co-εcaprolactone) (PLCL) copolymers have been applied as a biomaterial for vascular graft due to the high elastic property. We previously repor...

OBJECTIVE To study the possibility of removing nitrogen, phosphorus, and organic pollutants using seeding type immobilized microorganisms. METHODS Lakes P and M in Wuhan were chosen as the objects to study the removal of nitrogen, phosphorus, and organic pollutants with the seeding type immobilized microorganisms. Correlations between the quantity of heterotrophic bacteria and the total nitro...
