The dispersion stability of CeO 2 suspensions limits their widespread use in IC manufacturing because unstable slurries can be very damaging to the chemical mechanical polishing (CMP) flattening process. Therefore, this study is based on wet ball milling synergy with agents improve slurry. Different organic acids were used as adjusting agents, including acetic acid, propionic lactic and phytic ...

This study investigated waste activated sludge (WAS) and food (FW) co-fermentation in batch assays to produce carboxylic acids. Three mixtures (50%, 70% 90% WAS VS basis) were studied under different conditions: with without extra alkalinity, auto-hydrolysis pre-treatment. All tests carried out at 35 °C, pH adjustment external inoculum. Experimental results showed that yields, including volatil...

A combination of multiple hurdles to limit microbial growth is frequently applied in foods to achieve an overall level of protection. Quantification of hurdle technology aims at identifying synergistic or multiplicative effects and is still being developed. The gamma hypothesis states that inhibitory environmental factors aiming at limiting microbial growth rates combine in a multiplicative man...

The article deals with the study on content of fecal short-chain fatty acids (SCFA) and their association insulin resistance in obese children. It was found that intestinal microflora children is characterized by changes qualitative composition increased metabolic activity microflora. A moderate increase HOMA-IR accompanied elevated concentration anti-inflammatory cytokines, which correlates ac...

In previous work Armstrong & Blaxter (1957) found that when acetic acid was given to fasting sheep as the sole source of energy it was inefficiently utilized in the sparing of body tissues from oxidation. Five experiments gave a mean heat increment of 40.9 kcal/Ioo kcal of acid metabolized, a value which greatly exceeded the heat increments found when propionic or n-butyric acids were given. A ...

this study examined the effects of a protein rich diet on coping neurotransmitter levels in orally administered ampicillin–induced neurotoxic rats compared with propionic acid (pa) models of autism. 40 young male western albino rats were divided into four groups. the first group served as control and received phosphate buffered saline orally; the second group serving as autistic model was treat...

background: fenugreek (trigonella foenum - graecum l.) is an annual medicinal plant belongs to the legume family and has anti-diabetic, anti-fertility, anticancer, anti-microbial, anti-parasitic and hypocholesterolaemic effects. objective: evaluation of growth and trigonelline /mucilage content in fenugreek under application of plant growth regulators (pgr). methods: the experiment was conducte...
