In this paper we study the sedimentation of 6400 circular particles in 2D using the method of distributed Lagrange multipliers for solid-liquid flow. The simulation gives rise to fingering which resembles Rayleigh-Taylor instability. The waves have a welldefined wavelength and growth rate which can be modeled as a conventional RayleighTaylor instability of heavy fluid above light. The heavy flu...

Chemical burns, mainly produced by acids, are a topic of concern. A new sensing material for the detection of strong acids able to be incorporated into textiles has been developed. The material is prepared by the covalent attachment of 2,2',4,4',4″-pentamethoxy triphenyl methanol to a mesoporous material which further is included in a nitro resin to obtain a colourless composite. The response o...

Low-salt solid-state fermentation soy sauce was prepared with defatted soy bean and wheat bran. Biochemical changes during the aging of the soy sauce mash were investigated. Results showed that after a 15-day aging period, the contents of total nitrogen, formol titration nitrogen, free amino acids, reducing sugar, total sugar and the brown color were increased. However, pH was decreased during ...

Cognitive impairment is strongly associated with functional outcome in patients with schizophrenia but its pathophysiology remains largely unclear. Involvement of omega-3 fatty acids in the cognitive function of healthy individuals and patients with neuropsychiatric disease has received increasing attention. The aim of this study was to examine the relationship between omega-3 fatty acids with ...

toktam faal rastegar was born in quchan (iran). she completed her b.sc. in chemistry in 2005 from ferdowsi university, mashhad. she was graduated from m.sc. degree in organic chemistry from bu-ali sina university (2008), hamadan, iran. she is currently organic chemistry ph.d student under the supervision of prof. a. khazaei and prof. m.a. zolfigol in department of chemistry at bu-ali sina unive...

Fatty acids and fatty alcohols have the advantages of high latent heat phase change, good thermal stability, no corrosion, supercooling separation. They can be used as change energy storage materials for passive temperature control. However, their popularization application are limited because transition narrow range. This study develops a novel binary composite (PCMs) Capric acid (CA) Octadeca...

          Ag-Cu solid solutions prepared via ball milling process were subsequently milled for 30 h and investigated by X-ray diffraction technique for Cu-20%Ag, Cu-3.64%Ag and Cu-80%Ag. It was noted that the solid solubility level increased by increasing initial solute content in composition. Results showed peak positions of silver and copper changed with milling time. By heating up to 700 K, ...

3. The ether-extractable acids were separated into solid and liquid acid fractions, converted into methyl esters and fractionally distilled. The light petroleum-insoluble compounds were separated from the fractions. Analyses of the acids are given (Table 2): these show that the increases after cholesterol feeding occur in the solid, liquid and light petroleum-insoluble fractions. 4. The methyl ...

The black soldier fly larvae (BSFL) is a sustainable ingredient for feed applications, biofuels, composite materials and other biobased products. Processing BSFL to obtain lipid protein fractions with enhanced functional properties as suitable replacement conventional ingredients has gained considerable momentum. In this regard, novel wet mode fractionation (WMF) scheme was explored. Fresh were...
