In the framework of a cohort study of pregnant women conducted in Brittany (France), we assessed the exposure to trihalomethanes (THM) during pregnancy in a subset by evaluating (1) potential sources of variability in household THM levels; (2) the between- and within-subject variability in THM levels; (3) THM levels in swimming pools; and (4) the role of water-related habits on total THM uptake...

Introduction Skeletal muscle is the body’s largest organ and is essential to many aspects of human physiology, including movement, glucose uptake and storage, thermogenesis, and total body water balance. MRI methods allow investigators to assess many aspects of muscle structure and function. A key point of focus for this abstract and presentation will be the muscle microvasculature, the proper ...

Trees of tropical semi-deciduous forests range from "drought-avoiding" stem-succulent species with low-density wood (< 0.5 g cm(-3)), which maintain high stem water potentials (psi(STEM) > -0.7 MPa) throughout the year, to "drought-tolerant" deciduous hardwood species (wood density > 0.75 g cm(-3)), which dehydrate strongly during seasonal drought (psi(STEM) < -6 MPa). In stem-succulent and oth...

Objective (s): Mucoadhesive disc is one of the various routes of drug delivery for curing buccal disease.Materials and Methods:Everydiscs containing 70 mg stem bark extract of Ziziphus jujuba were formulated  by using Carbopol 934, PVP k30 and gelatin as polymers. Discs were made by granulation  and direct compression. Discs were standardized based on the total phenol.  Properties such as in vi...

the effects of an azotobacter chrococum isolate (strain ag11) and vermicompost and their combined effects on a rain-fed winter wheat (var. zagros) nutrient uptake and growth and soil water content were investigated with a farm trial.  the dry matter yield was determined in 5 occasions. gravimetric soil water content, soil microbial respiration and the number of azotobacter were determined at sa...

heterogeneous proton exchange membranes (pem) are synthesized using the dry phase inversion technique. the casting solutions are prepared by dispersing a finely ground cation exchange resin particle in n,n-dimethylacetamide (dmac) solution of polyvinyl-chloride (pvc). results show that ion exchange capacity is increased with the addition of 1 %-wt nanosilica (from 0.14 to 0.27 meq/g) while it i...

Split root experiments have the potential to disentangle water transport in roots and soil, enabling the investigation of the water uptake pattern of a root system. Interpretation of the experimental data assumes that water flow between the split soil compartments does not occur. Another approach to investigate root water uptake is by numerical simulations combining soil and root water flow dep...

Growing on rooting media other than soils in situ -i.e., substrate-based growing- allows for higher yields than soil-based growing as transport rates of water, nutrients, and oxygen in substrate surpass those in soil. Possibly water-based growing allows for even higher yields as transport rates of water and nutrients in water surpass those in substrate, even though the transport of oxygen may b...

The fresh water Indian neopterigian teleost, Cyprinuscarpio, a common carp deals with some aspect concerning chromatic regulatory mechanisms, within the boundary of the two points of view: one of these is the value of colour pattern, as signals to other animals for the purpose of recognition, stimulation or warning or for the purpose of concealment of predator of prey. In this field is included...
