Physical literacy is a concept that is expected to encompass the mind and body in an integrated way to explain, promote, and help sustain human beings’ fundamental function: movement. According to Whitehead (2010), physical literacy is defined by motivation, especially by competence-based and interest-based motivation. This point of view is consistent with vast amount of research evidence on …

Oyster-derived polysaccharides (OPS) have been shown to modulate the T helper (Th)1/Th2 immunobalance toward the Th1-dominant direction in antigen-primed splenocytes. In the present study, we hypothesized that OPS might attenuate intestinal inflammation associated with food allergy, a Th2-dominant immune disorder.

Fang Chen

Newer statistical procedures are typically introduced to help address the limitations of those already in practice or to deal with emerging research needs. Quantile regression (QR) is introduced in this paper as a relatively new methodology, which is intended to overcome some of the limitations of least squares mean regression (LMR). QR is more appropriate when assumptions of normality and homo…

We present an endogenous growth model in which both the investmetit to develop a new technology—that upgrades the quality of machines—and entry of imitators are determined endogenously. According to the model, how soon the new-technology machine is launched after the patent is granted is influenced by two factors: returns to scale in technology development and "strategic delays."

Microbial polyhydroxyalkanoates (PHA) were proposed for the first time as a new type of biofuel. In this paper, poly-R-3-hydroxybutyrate (PHB) and medium chain length PHA (mcl PHA) were, respectively, esterified to become R-3-hydroxybutyrate methyl ester (3HBME) and medium chain length hydroxyalkanoate methyl ester (3HAME) via acid-catalyzed hydrolysis. The recovery percentages of 3HBME and 3H…

Diffusion and Flow Across Nanoporous Polydicyclopentadiene-Based Membranes
Komentar Bagikan
William A. PhillipMark AmendtBrandon O’NeillLiang ChenMarc A. HillmyerEdward L. Cussler

ABSTRACT We report gas and liquid transport measurements through membranes that have 40% voids made of 14 nm pores. A reactive polylactide-polynorbornenylethylstyrene block polymer is used as a structural template in the polymerization of dicyclopentadiene during the membrane formation process. After the membrane is cast, the pore structure is formed by etching the polylactide component using…

Feitsui reservoir, the major water supply of Taipei city, has shown declining water quality in recent years. The reservoir is located in an area famous for tea cultivation, and the question arises as to whether the hillside tea plantations have contributed to increased sediment and nutrient discharge into the reservoir. In this study, soil and phosphorus redistribution were examined along a …

Aims.Understanding the response of farmland weed community assembly to fertilization is important for designing better nutrient management strategies in integrated farmland ecological systems. Many studies have focused on weed characteristics, mainly crop–weed competition responses to fertilization or weed communities alone.However, weed community assembly in association with crop growth is p…

Economic, Energy Security,And Greenhouse Gas Effects Of Biofuels: Implication…
Komentar Bagikan
Madhu KhannaXiaoguang Chen

Existing studies show that biofuels offer the potential for providing energy security and GHG mitigation, particularly with the development of cellulosic biofuel technologies, even after market-mediated effects are incorporated. The economic benefits with biofuel policies, arising due to the improvement in terms of trade for the United States, could, however,be several times larger than thes…

Auxin-like 2,4-dichlorophenoxyacetic acid (2,4-D), a high-efficiency anti-stalling agent for the post-harvest fresh fruit industry, has had its use restricted due to environmental concerns. However, no other substitutes for 2,4-D are available to the post-harvest industry. Insights into the molecular mechanism underlying the effects of 2,4-D on fruit quality preservation will provide a theoreti…
