The polypyrrole (PPY/TW) and magnetic (MG/TW) composite with tea waste (TW) was prepared used as an adsorbent for PO43− ions removal from aqueous media. were characterized SEM FTIR techniques. Batch study conducted to investigate the effect of different reaction parameters on adsorption ions. native TW, PPY/TW, MG/TW showed 7.2, 7.3, 7.9 (mg/g), respectively, using 0.05 g dose 10 mg/L initial c...

We prove that, for every n-vertex graph G, the treewidth of G plus the treewidth of the complement of G is at least n − 2. This bound is tight. © 2012 Gwenaël Joret and David R. Wood. Published by Elsevier Ltd. All rights reserved. Nordhaus–Gaddum-type theorems establish bounds on f (G) + f (G) for some graph parameter f , where G is the complement of a graph G. The literature has numerous exam...

A leading cause of cancer chemotherapy failure is chemoresistance, which often involves multiple mechanisms. Chinese medicines (CM) usually contain multiple components which could potentially target many mechanisms simultaneously and may offer an advantage over single compounds that target one mechanism at a time. The purpose of this study was to investigate the chemosensitizing effect (CE) of ...

The present study examines prosodic characteristics of Taiwan (TW) English in relation to native (L1) English and TW speakers’ mother tongue, Mandarin. The aim is to investigate 1) how TW second-language (L2) English is different from L1 English by integrated prosodic features 2) if any transfer effect from L2s’ mother tongue contributes to L2 accent and 3) What is the similarity/difference bet...

– The relation between the autocorrelation C(t, tw) and the integrated linear response function χ(t, tw) is studied in the context of the large-N model for phase-ordering systems subjected to a shear flow. In the high temperature phase T > Tc a non-equilibrium stationary state is entered which is characterized by a non-trivial fluctuation-dissipation relation χ(t − tw) = ˜ χ(C(t − tw)). For que...

The low-temperature dynamics of the twoand three-dimensional Ising spin-glass model with Gaussian couplings is investigated via extensive Monte Carlo simulations. We find an algebraic decay of the remanent magnetization. For the autocorrelation function C(t ,tw)5@^Si(t1tw)Si(tw)&#av a typical aging scenario with a t/tw scaling is established. Investigating spatial correlations we find an algebr...

Betula platyphylla Suk (birch) is a fast-growing woody species that is important in pulp industries and the biofuels. However, as an important pulp species, few studies had been performed on its wood formation. In the present study, we investigated the molecular responses of birch xylem to artificial bending and gravitational stimuli. After trunks of birch trees were subjected to bending for 8 ...

Aging dynamics in glassy systems is investigated by considering the hopping motion in a rugged energy landscape whose deep minima are characterized by an exponential density of states ρ(E) = T g exp(E/Tg), −∞<E≤0. In particular we explore the behavior of a generic two-time correlation function Π(tw+t, tw) below the glass transition temperature Tg when both the observation time t and the waiting...

Tension wood (TW) is a specialized tissue with contractile properties that is formed by the vascular cambium in response to gravitational stimuli. We quantitatively analysed the proteomes of Populus tremula cambium and its xylem cell derivatives in stems forming normal wood (NW) and TW to reveal the mechanisms underlying TW formation. Phloem-, cambium-, and wood-forming tissues were sampled by ...

Two experiments were conducted to evaluate the effects of drinking water temperature (Tw) on laying hens subjected to warm cyclic air temperature (Ta) conditions. Each experiment consisted of a 1-wk acclimation under thermoneutrality (TN) (Ta = Tw = 21 C), a 4-wk heat exposure or treatment period, and a 2-wk recovery under TN. Each experiment involved 24 individually caged hens at the initial a...
