1.Structure-rheology relationship in a sheared lamellar fluid.
Jaju SJ1, Kumaran V1. Phys Rev E. 2016 Mar;93(3-1):032609. Epub 2016 Mar 22.
The structure-rheology relationship in the shear alignment of a lamellar fluid is studied using a mesoscale model which provides access to the lamellar configurations and the rheology. Based on the equations and free energy functional, the complete set of dimensionless groups that characterize the system are the Reynolds number (ργ[over ̇]L^{2}/μ), the Schmidt number (μ/ρD), the Ericksen number (μγ[over ̇]/B), the interface sharpness parameter r, the ratio of the viscosities of the hydrophilic and hydrophobic parts μ_{r}, and the ratio of the system size and layer spacing (L/λ). Here, ρ and μ are the fluid density and average viscosity, γ[over ̇] is the applied strain rate, D is the coefficient of diffusion, B is the compression modulus, μ_{r} is the maximum difference in the viscosity of the hydrophilic and hydrophobic parts divided by the average viscosity, and L is the system size in the cross-stream direction. The lattice Boltzmann method is used to solve the concentration and momentum equations for a two dimensional system of moderate size (L/λ=32) and for a low Reynolds number, and the other parameters are systematically varied to examine the qualitative features of the structure and viscosity evolution in different regimes.

The rigid and planar tetracarboxylic acid 5,5'-(1H-2,3,5-triazole-1,4-diyl)diisophthalic acid (H4L), incorporating a triazole group, has been used with no or different pyridine-based linkers to construct a family of d10 coordination polymers, namely, {[H2N(CH3)2]3[Cd3(L)2(HCOO)]}n (), {[Cd2(L)(py)6]·H2O}n (), {[H2N(CH3)2] [Cd2(L)(HCOO)(H2O)4]}n (), {[Zn(H2L)]·H2O}n (), and {[Zn(H2L)(4,4'-bipy)0.5]·C2H5OH·H2O}n () (py = pyridine, 4,4'-bipy = 4,4'-bipyridine). constructs a 3D porous network containing two kinds of channels: one is filled with coordinated HCOO- anions, and the other with [H2N(CH3)2]+ cations. The framework of can be described as a rare (5,6,7)-connected net with the Schläfli symbol of (412·5·62)(45·53·62)2(48·53·68·82)2. The Cd(ii) ions in are connected through the carboxylate ligands to form a 2D layer, with aperture dimensions of ∼15.1 Å × 16.2 Å. The network of features a 3D (3,4)-connected (6·8·10)2(6·83·102) topology. A 3D network with the (42·6·83) topology of possesses an open 1D channel with the free volume of 29.

Drinking water is a main source of human exposure to arsenic. Hence, the determination of arsenic in groundwater is essential to assess its impact on public health. Here, we report arsenic levels in the groundwater of 722 sites covering all six major provinces of Korea. Water was sampled in two occasions (summer, 722 sites and winter, 636 sites) and the arsenic levels were measured with highly sensitive inductively coupled plasma-mass spectrometry method (limit of detection, 0.1 μg/l) to encompass the current drinking water standard (<10 μg/l). Seasonal variation was negligible, but the geographical difference was prominent. Total arsenic in groundwater ranged from 0.1 to 48.4 μg/l. A 88.0-89.0% of sites were <2.0 μg/l and the remaining ones generally did not exceed 10 μg/l (6.4-7.0%, 2.0-4.9 μg/l; 2.4-3.0%, 5.0-9.9 μg/l). However, some areas (1.0-9.2%) exhibited >10 μg/l. Notably, urinary arsenic excretion of people around these regions was markedly higher compared with non-contaminated areas (<5 μg/l) (79.

INTRODUCTION    Increased C-reactive protein (CRP) concentrations during pregnancy are associated with several perinatal complications. OBJECTIVES    The aim of the study was to assess serum CRP concentrations and identify its determinants in pregnant women with type 1 diabetes. PATIENTS AND METHODS    CRP concentrations were determined using a high-sensitivity assay (hs-CRP) in the first trimester (I, week <12 of gestation), in mid-pregnancy (II, weeks 20 to 24 of gestation), and in the late third trimester (III, weeks 34 to 39 of gestation) in a group of 73 patients with type 1 diabetes. RESULTS    There was a significant increase in CRP concentrations between the first trimester and mid‑pregnancy (median [interquartile range], 2.5 mg/l [1.3-4.5 mg/l] and 5.6 mg/l [2.5-11.6 mg/l]; P = 0.0001), which then stabilized with no further change between mid-pregnancy and the late third trimester (5.7 mg/l [2.5-9.6 mg/l]). CRP concentrations in all 3 trimesters were positively correlated with the waist‑to-hip ratio (I, P <0.
