In tissue engineering, polymer-based scaffolds play an important role via cell adhesion, proliferation, and regeneration in three-dimensional (3D) structures, exhibiting great potential a variety of tissues. For fabrication scaffolds, the particulate-leaching method thermally-induced phase separation (TIPS) are popular procedures. However, complete interconnectivity porous structure has not bee...

This article presents an estimation of the temperature decrease in vicinity a salt cavern due to its leaching. The one-dimensional radially symmetry models were considered and described. initial rock massif was assumed as 50 ∘C leaching water varied seasonally from 6 20 ∘C. A significant influence season process, beginning on final distribution found. model takes into account: convection coeffi...

Foreign approaches to maintaining a favorable salt regime of soils are analyzed. On the basis experimental studies, change in water-physical properties soil during deep loosening and an increase leaching vegetation irrigation using Biosolvent preparation were established. Based on analysis results, optimal technologies norms for saline have been

Pig farming produces more manure than can reasonably be spread onto surrounding fields, particularly in regions with high livestock densities and limited land availability. Nutrient recycling offers an attractive solution for dealing with manure excesses and is one main objective of the European commission-funded project “BioEcoSIM”. Phosphate salts (“P-Salt”) were recovered from the separated ...

[1] A minimalist stochastic model of primary soil salinity is proposed, in which the rate of soil salinization is determined by the balance between dry and wet salt deposition and the intermittent leaching events caused by rainfall events. The long term probability density functions of salt mass and concentration are found by reducing the coupled soil moisture and salt mass balance equation to ...

Porogen leaching is a widely used and simple technique for the creation of porous scaffolds in tissue engineering. Sodium chloride (NaCl) is the most commonly used porogen, but the current grinding and sieving methods generate salt particles with huge size variations and cannot generate porogens in the submicron size range. We have developed a facile method based on the principles of crystalliz...

Planned implementation of a nitrogen (N) “cap” on land in the Lake Taupo catchment has led to the need for a range of N mitigation options for pastoral farmers to increase profitability while farming within the N cap. A multi-disciplinary research programme has focused on the potential of targeting different parts of the N cycle to increase N efficiency and reduce N leaching losses. A range of ...
