primary bud necrosis (pbn) in grapevine is a physiological disorder that leads to death of fruitful buds and yield loss. the aim of this study was to determine the changes in soluble sugars and starch and their relationship to the incidence of the primary bud necrosis in askari grapevine. experiment was conducted in a vineyard that the vines were 15 years old, with a head system, vines spaced 2...

Liquid spreading on a soluble substrate is known as dissolutive wetting, common phenomenon in the medical and industrial fields. However, dynamic process of wetting not fully understood due to complex transport mass momentum. In this article, we present hydrodynamic model that accounts for both Marangoni buoyancy effects analyze interface shape, flow, solute wetting. Based our theoretical analy...

The cogrinding technique is one of most effective methods for improving the dissolution of poorly water-soluble drugs and it is superior to other approaches from an economical as well as an environmental standpoint, as the technique does not require any toxic organic solvents. Present work explores the role of d-glucosamine HCl (GL) as a potential excipient to improve dissolution of a low melti...

The purpose of this study was to develop porous silica nanoparticles (PSNs) as a carrier to improve oral bioavailability of poorly water-soluble drugs, using silymarin as a model. PSNs were synthesized by reverse microemulsion and ultrasonic corrosion methods. A 3-day release formulation consisting of a silymarin solid dispersion, a hydrophilic gel matrix and silymarin-loaded PSNs was prepared....

Poorly solubility in water of many newly developed high-potential drugs is an obstacle in formulation development. The aim of this study was to increase the solubility of Lamotrigine which is a poorly soluble drug and comes under BCS class-II by using solid dispersion technique. Lamotrigine, PEG 4000 and PVPK-30 solid dispersion was prepared by solvent evaporation method and the formulation was...

According to the result of this study, there was a significant increase in the amount of sugars including rhamnose, glucose and mannose from October for Abbot and Hayward and from August for Allison until harvesting time (late November). During one month of post harvesting time, the fruits showed no significant changes in sugar concentration except for the Hayward that showed a significant incr...

the present experiment aimed at increasing orange peel and sugar beet pulp protein content through solid-state fermentation by trichoderma reesei and trichoderma viride. in vitro digestibility and changes in the chemical composition of the fermented products were determined after seven days of fungal cultivation using gas production tests. the cultivation of t. reesei and t. viride on orange pe...

New bis(N,N-trimethylsilylarylamidinate) zirconium dichloride complexes with various carbon substituents were prepared, and their solid as well as solution state structures were studied. In the polymerization of propylene, after activation by MAO, these catalysts provided two fractions. Ether soluble polymers were obtained at a low activity as sticky polymers with lower molecular weights, excep...

introduction: malt extract is one of the malt products obtainedfrom concentrations of water soluble extract of grains such as barley and is a proper alternative to white sugar. it has a high diastasis properties andcontainshigh amount of different vitamins specially the group of vitamin b as well as high amount of fermentable sugars. therefore, malt extract has high nutritional value and is rec...

Abstract Spent Pot Lining (SPL) cathode pot, waste from the aluminium smelting process needs detoxification cyanides, washing out water-soluble salts and extraction of cryolite (Na 3 AlF 6 ) decomposition products to be recycled. Revealed mechanism with NaOH opens possibilities explore its critical role in reactive process. Common Na + ion hinders solubility product but also drives mass transfe...
