abstract sensitive and precise voltammetric methods for the determination of trace amounts of furaldehydes, mainly as furfural (f) and 5-hydroxymethyl-2-furaldehyde (hmf), in waste waters and other matrices is described. determination of total furaldehyde at < ?g g-1 levels in alkaline buffered aqueous media was individually investigated. by the use of ordinary swv and adsorptive square wave ...
the history of plant’s used for mankind is as old as the start of humankind. initially, people used plants for their nutritional proposes but after the discovery of medicinal properties, this natural ?ora became a useful source of disease cure and health improvement across various human communities. berberis vulgaris is one of the medicinal plants used in iranian traditional medicine. berberis ...
most plants are able to increase soil phosphorus availability by exuding some compounds such as organic acids when they experience phosphorous deficiency. considering this special ability of plants, the main purpose of the present research was to investigate if application of organic acids may increase p availability in soil. therefore, a greenhouse experiment was conducted with five treatments...
Changes in the mineral composition of mare milk during lactation were studied. Milk samples were obtained from five Thoroughbred mares 0"«^« thr• times weekly from the first to the eighth week of lactation and from two of the mar^ for an additional 8 wk. Samples averaging 500 mL were obtained after oxytoc.n was administered to the mares. Each sample was analyzed for total sohds, ash ca ciuna is...
background: association between the vitamin d deficiency and metabolic syndrome (mets) has previously been noted and reported to be controversial. the aim of this study was to determine the association of serum 25 (oh) d level and vitamin d dietary intake with mets among iranian population . methods: this analytical study was conducted on 122 patients with mets based on the atpiii criteria and ...
The addition of pond ash (fly ash that has been placed in evaporative ponds and subsequently dewatered) to feedlot surfaces provides a healthier environment for livestock and economic advantages for the feedlot operator. However, the water quality effects of pond ash amended surfaces are not well understood. The objectives of this field investigation were to: (1) compare feedlot soil properties...
At calving time, the cows were monitored and blood samples were taken from jugular vein of 38 cows with parturient paresis and 38 healthy ones. The levels of calcium, phosphorus, magnesium, sodium, potassium, chloride, glucose, triglyceride, cholesterol, albumin, globulin and A/G ratio were assessed to find the correlation between the degree of hypocalcemia and other parameters. According to ca...
in this thesis a calibration transfer method is used to achieve bilinearity for augmented first order kinetic data. first, the proposed method is investigated using simulated data and next the concept is applied to experimental data. the experimental data consists of spectroscopic monitoring of the first order degradation reaction of carbaryl. this component is used for control of pests in frui...
The effects of ash and commercial fertilizers on the foliar nutrient concentrations and stand growth of Scots pine were studied in four fi eld experiments established on former cultivated peat soils. The aims were to compare ash types (wood, peat and coal ash), study the effects of ash treatment (pelletization), compare ash fertilization with commercial fertilizers, and to study the interaction...
