Crystal soaking is widely performed in biological crystallography. This paper reports time-resolved X-ray crystallographic and microtomographic analyses of tetragonal crystals of chicken egg-white lysozyme soaked in mother liquor containing potassium hexachloroplatinate. The microtomographic analysis showed that X-ray attenuation spread from the superficial layer of the crystal and then to the ...

This work describes the optimization of cryogenic treatment (CT) parameters such as the cooling rate, the soaking temperature, the soaking time, the tempering temperature and the tempering time to maximise the tool wear of high speed steel tools in dry turning of AISI 316 grade austenitic stainless steels by Taguchi method. For this purpose, four iteration of Taguchi design (L16) have been used...

Rooting and shoot growth were evaluated on stem tip cuttings of砂pencumpe功ratum receiving various auxin soaking treatments. Five-cm-Iong stem tips (0.08 g fresh weight in average) were soaked in IAA, 1 BA, NAA and 2,4-D solutions at 5, 25 , 125μM for 10 min, and then placed in a rockwool block for three weeks. A deionized water soaking treatment was served as a control. The results indicated tha...

Durian seed is an agricultural biomass waste of durian fruit. It can be a natural plant source of non-starch polysaccharide gum with potential functional properties. The main goal of the present study was to investigate the effect of chemical extraction variables (i.e., the decolouring time, soaking temperature and soaking time) on the physicochemical properties of durian seed gum. The physicoc...

Dicalcium phosphate dihydrate (DCPD) reacts with fluoride ion in an aqueous solution and forms stable fluoroapatite (FAp). This reaction requires a lag time to form nano-sized precursor, hydroxyapatite (HAp)-like calcium phosphate, on DCPD surface. This long lag time prevents DCPD from applying as an effective fluoride removal agent from waste water. The purpose of this study is to improve the ...

Corn fractionation in modified dry grind processes results in low fermentation efficiency of corn grits because of nutrient deficiency. This study investigated the use of nutrient-rich water from germ soaking to improve grits fermentation in the conventional dry grind and granular starch hydrolysis (GSH) processes. Comparison of germ soak water with the use of protease and external B-vitamin ad...

in this research,the effect of power ultrasound (20 khz ,800 and 1000w) at 20.40 and 60 minutes on physico-chemical properties of two rice varieties tarom and neda was investigated and by the soaking method in controlled temperature (47°c) compared.results showed the maximum amount of water absorption of rice, observed at 60 minutes ultrasound treatment (1000w) and the lowest was observed in co...

laboratory experiments were performed to determine the effect of various scarification treatments at four temperature regimes on germination of licorice seeds . a randomized complete block design with four replications was used. germination counts were made every day for 2 weeks. at 50c, none of the chemically and mechanically scarified and non scarified seeds germinated. at 15, 25, and 350...

biomimetic method was used to apply hydroxyapatite (ha) coating onto ti6al4v cylinders. this process is a physicochemical method in which a substrate is soaked in a solution simulating the physiological conditions, for a period of time enough to form a desirable layer of the calcium phosphate on the substrate. in the present study, specimens were soaked in 5, 10 m solutions of naoh at temperatu...

Pistacia vera L. is a decidious tree. To investigate the influence of soaking seeds in polyamines (PAs) spermine (Spm), spermidine (Spd) and putrescine (Put) on seed germination and enhancing lateral root development of ‘Ghazvini’ pistachio seedling rootstock, the experiment were carried out in petri dishes and plastic bags. Seeds were soaked in PAs( Spd, Spm, and Put) at three concentrations( ...
