By selecting and optimising lactic acid bacteria, maximum amount of gamma-aminobutyric acid (GABA) in fermentation broth can reach 0.54 g/100 ml, which is very low. Ultrafiltration (UF) process can effectively separate and purify GABA fermentation broth, so as to increase the GABA content. After pre-treatment with high speed centrifugation, the opt...

To selectively reduce the delivery of hydrocyanic acid (HCN) in mainstream cigarette smoke, a porous material with metal-organic framework (MOF), copper-1, 3, 5-benzenetricarboxylic acid (II) (Cu-BTC), was prepared by hydrothermal synthesis method.

Numerical simulation of aircraft's flutter is rather expensive and time-consuming. In order to save expense and calculating time, an efficient fluid-structure interaction solver based on multigrid is developed. The flow governing equations coupled with aeroelastic equations are solved using finite volume algorithm based on multigrid method. For the...

Period2 is a core circadian gene, which not only maintains the circadian rhythm of cells but also regulates some organic functions. We investigated the effects of mPeriod2 (mPer2) expression on radiosensitivity in normal mouse cells exposed to 60Co-gamma-rays. NIH 3T3 cells were treated with 12-O-tetradecanoylphorbol-13-acetate (TPA) to induce endo...

A new approach using control theory for the aerodynamic optimization design of elastic wing where aeroelastic interactions are significant is implemented and tested. Aero-Structural analysis has been carried out by coupling flow control equations solver and finite-element structural solver in which high-fidelity models are used. In design process,...

Biological clocks are intrinsic time-keeping systems that regulate behavior and physiological functions in most living organisms. Previous works suggested a possible link between the endogenous circadian clock and cell cycle regulation. The mammalian Period-2 gene (mPer2), an important component of the circadian clock mechanism, is recently demonst...

To investigate the effects of circadian gene Period2(Per2) expression level on proliferation and radiosensitivity of tumor cells, the Per2 expressing vector (pcDNA 3. 1-Per2) was transfected into the cultured C6 cells(C6 glioma cells) by liposome method in vitro. The expression of Per2 in the transfered C6 cells was detected by immunohistochemistry...

To study the effects of circadian mPeriod2(mPer2) gene over-expression on radiosensitivity of Lewis lung cancer cells( LLCs) in vitro, Lipofectamine-mediated gene transfection method was used to transfect mPer2 into LLCs. The expression of mPer2 was determined by PT-PCR and flow cytometry( FCM). After single 4 Gy 60Co-γ ray radiation, the distribut...

To study both of the curative effect and the toxic and side effect from chronoradiotherapy and routine radiotherapy used to treat nasopharyngeal carcinoma (NPC), sixty-five patients with NPC who receiving primary treatment were randomly divided into two groups, one was chronoradiotherapy group (TV = 34) and the other was routine group (N = 31). Sam...

Based on the optimal control theory and Navier-Stokes equations, aerodynamic design of airfoil with multi-constraint conditions, such as aerodynamic and geometric constraint conditions, is studied. According to a given problem, the corresponding adjoint equations, boundary conditions and final cost function formulation are derived in the computatio...

Based on control theory and Navier-Stokes equations, a new aerodynamic design method is studied.

A highly manufacturable technique for improving transistor performance is reported.

Widespread acceptance of industrial by-products as agricultural soil amendments depends on research data to support their benefits in terms of crop growth, production or quality, and demonstration of no adverse effects on the quality of crops, soils, and/or groundwater. The sulfur dioxide scrubbing process during coal burning to minimize atmospheri...

The effect of gypsum amendment on transport of phosphorus (P) in a Pineda sand (loamy, silicious, hyperthermic Arenic Glossaqualf) was investigated in a leaching column experiment. Phosphorus was either placed on the surface of the soil or mixed with the surface 2 cm depth of soil in the column. Gypsum amendment decreased the transport of P in soil...

Mehlich 1 (M1), Mehlich 3 (M3), and Ammonium Bicarbonate DTPA (AB-DTPA) have been used to determine the available micronutrients in soils. However, the forms of micronutrients extractable by these extractants are not known. The objectives of this study were: (i) to examine the correlation between the forms of Zn or Cu (readily soluble, organically...

Copper (Cu) phytotoxicity is closely related to pH and Cu activity in solution. The effect of pH on growth and uptake of Cu by Swingle citrumelo rootstock seedlings were investigated in solution culture with varying Cu activities. Copper activities of either 0.05, 0.5, 5, and 10 μM at pH 5 and 6 were maintained by adding copper sulfate (CuSO4) to t...

This study was conducted to determine the effects of either gypsum, MgSO4, or K2SO4 on transport of Cu, Zn, Ca, and Mg from a slighly alkaline sandy soil (top 15-cm layer) using leaching columns.
