Reduction of Solid Uranium Dioxide in Calcium Salts
… The system designs have been optimized in calcium salts since they have high calcium metal and calcium oxide solubility. The significant results indicated that both methods would substantially reduce the solid uranium dioxide pellet. The chemical reduction will reduce the total solid pellet …

Niacin-lipid interactions in lactating dairy cows
… were: control, nicotinic acid (12 g/d), calcium salts of long chain fatty acids (3% diet dry matter), and calcium salts of fatty acids with nicotinic acid. Cows received treatment diets from week 2 to week 14 postpartum.

Effects of feeding increasing dietary concentrations of fat on the performance of lactating dairy cows
… 1 treatments were: control, no fat; control, 3% calcium salts of long-chain fatty acids (Ca-LCFA); control, 6% Ca-LCFA; and control, 9% Ca-LCFA. Dry matter intake and production of milk, milk protein, and solids-not-fat (SNF) were not altered greatly by feeding up to 6% Ca-LCFA in the diet. …

Investigation of the effect of hydroxycitric acid on urinary calcium oxalate risk factors for kidney stone formation in artificial urine: theoretical modelling and in vitro crystallisation experiments
… stones are composed of different mineral types. Calcium Oxalate is the most common kind of stone. The principal aim of this research was to establish whether hydroxycitrate (HCA) affects and/or inhibits calcium oxalate crystallisation. A three-pronged approach was adopted, involving the …

The effect of inositol-hexakisphosphate (phytate) on urinary risk factors for calcium oxalate urolithiasis in South African population groups with different kidney stone risk profiles : theoretical modelling, in vitro crystallisation experiments and in vivo human studies
… of this thesis were to establish whether soluble calcium-phytate complexes inhibit calcium oxalate crystallisation and whether a higher dietary intake of phytate in South African black subjects compared to white subjects may contribute to the relative rarity of urolithiasis in this group. …

Supplementation of omega-3 fatty acids as a strategy to regulate postpartum inflammation in dairy cows
… omega-3 (n3) fatty acids (FA) using calcium salts enriched in fish oil (Ca-FO) in the early postpartum period on the degree and resolution of inflammation using an induced acute inflammation model, and 2) test whether these effects were from the increased energy density of the diet or …

Interactions of Bovine Somatotropin and Nutrition on Milk Production and Composition of Dairy Cows
… energy as fat from extruded soybeans and calcium salts of fatty acids. Diets were 50:25:25 concentrate: alfalfa hay: corn silage (DM basis). Bovine somatotropin increased yields of milk (37.9 versus 40.9 kg/day) and of 4% fat-corrected milk (32.3 versus 35.7 kg/day). The HPE diet increased …

The synthesis and characterisation of novel long chain dimethyl siloxane surfactants.
… groups of these novel surfactants contained the salts of either a mono-, or a dicarboxylic acid. After the synthesis of these surfactants, the liquid crystal and micelle properties of the sodium and calcium salts, were investigated utilising a number of physical techniques eg. optical microscopy …

Extent of digestion of hydrogenated fats by ruminants
… 3: 81, 78, 70, 67, and 69% for control, calcium-salts of long-chain FA, prilled FA, and prilled and flaked hydrogenated palm FA distillate; and Experiment 4: 65, 65, 56, 34, 48, and 59% for control, tallow, partially HT, HT, HT and hydrogenated FA blend, and hydrogenated FA. The saturated …

Exploring the application of instrumental analysis for the conservation of textiles excavated in Greece
… state), ‘Kalyvia’<br/>(found impregnated with calcium salts) and ‘Nikaia’ (found in association with copper and in anoxic<br/>conditions). The quality of the results varied according to the type of preservation and the condition<br/>of the finds. The combination of stereomicroscopy, ESEM-EDS, …

Sonoluminescence for the quantitative analysis of alkali and alkaline earth chlorides
… from solutions of sodium, potassium, and calcium salts that have been analyzed and quantified from as low as parts per billion up to saturation concentrations. Over this wide range, spectral output is neither linear nor monotonic. Partial Least Squares analysis is used to quantify over …

Strategies for Improving Reproductive Efficiency of Beef Cattle with Assisted Reproductive Technologies
… rate. Experiment 2 examined how supplementing calcium salts of soybean oil (CSSO) improves beef cow fertility. Non-pregnant cows received supplement with either saturated fat or omega-6 rich CSSO. There were no changes in dominant follicle diameter, corpus luteum volume, plasma progesterone, or …

The characterisation of alginate systems for biomedical applications
… applications. The samples were prepared as mixed salts such as sodium/calcium salts as Ca2+ ions are known to promote faster healing. The aims of this research were: 1- to provide a greater insight into the nature of binding between various ions (NaT, Ca2+ as well as Zn2+ and Ag+) and the …

Crystal morphology and surface reactivity studies of calcium hydroxide
Calcium hydroxide samples, obtained as a precipitate from the mixing of solutions of sodium hydroxide with a variety of calcium salts in the optional presence of ethanol and a silylating agent, have been characterised by the techniques of nitrogen adsorption, water vapour adsorption , …

Promoting material circularity in pulp and paper mills: organic-inorganic cellulosic composites for slow-release of nutrients
… via wet coprecipitation with two different calcium salts from the pulp and paper mill system: calcium hydroxide (Ca(OH)₂) and calcium carbonate (CaCO₃). The immobilisation of urea was conducted via in-situ wet coprecipitation using Ca(OH)₂, forming a urea-hydroxyapatite (UHA) composite. A …

A Comparison of Cheddar Cheese Yields and Composition Using Conventional Bulk Set Cultures and Superstart Concentrated Cultures
… curd prior to drawing the whey. At higher pH, calcium salts and associated compounds are more insoluble, resulting in less acid soluble material being drawn off with the whey (57). However, the benefits claimed for Superstart cultures have not been substantiated under controlled conditions. …

Oxalate content of green juices and strategies for reduction of soluble oxalate content : A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University
… there is an interaction between the oxalate, calcium and the pulp fraction of the green juice. A 200 g glass of green juice containing a mix of apple, celery and spinach, contained 165.7 mg of soluble oxalate; this is a considerable amount of soluble oxalate to ingest. In the home, juicing …

Rice preparation for cadmium and arsenic reduction while maintaining a healthy microbial load
Paddy rice is a major source of exposure, globally, to the carcinogen and nephrotoxin cadmium and the carcinogen inorganic arsenic. As rice is a dietary staple, this makes rice production highly problematic. Thus, if cadmium and inorganic arsenic can be reduced in rice, even in rice based processed …
