Selection and Evaluation of Fruit Corn Varieties in Yanqing

Journal of Beijing University of Agriculture (2012)

Liu Zhi-xia

In order to determine the adaptability and quality of fruit corn varieties in Yanqing,this study introduced 12 fruit corn varieties to study their fertility characteristics,yield and quality.Results showed that: the picking period of Beijing Branch waxy fresh spike is 97d.The yield of Beijing Branch waxy 2000 up to 1208 kg/mu is the highest among the five waxy corn varieties which is 51.47% higher than the control,with significant difference,significant forward net spike rate,high seed rates,excellent overall performance compared with the control.The development potential of Beijing Purple Glutinous 218 and Jingke waxy 120 is better than the control.The fresh grain yield of Ke sweet crisp 1 and Jingke sweet is 15.18% and 14.08%,higher than the control respectively.The fresh grain yield of Ke sweet crisp 1,jingke sweet 2000,jingke sweet 126 reached significant level compared with the control.The sensory properties evaluation score of jingke waxy 2000,sweet single 21is ≥90.

An Indoor Positioning Algorithm Based on RSSI

Journal of Guangxi Academy of Sciences (2015)

Liu Zhi-xia

【Objective】There is great demand of indoor positioning technology.In order to improve the positioning accuracy at indoor environment,an improved indoor positioning algorithm is proposed in this paper.【Methods】This algorithm segments the overall region,and then distributs the beacon nodes by the equilateral triangle distribution model followed by pretreatment of Gauss model and the unknown node positioning by the improved weighted trilateration.【Results】The experimental results show that the advantages of algorithm is small error and high precise positioning.【Conclusion】The algorithm is suitable for precise indoor positioning.

Effects of Different Media on Paste Properties of Waxy Rice Starch

Acta Agriculturae Boreali-Sinica (2009)

Liu Zhi-xia

In different concentrations of sodium carbonate,alum,salt or sucrose,the viscosity curve of waxy rice starch was measured by Brabender viacometer to study the effects of these factors on starch paste properties.The result showed that adding sodium carbonate,alum,salt or sucrose could increase the temperature of gelatinization and the hot paste stability,and decrease the retro-gradation of waxy rice starch.Sodium carbonate,alum and salt,except sucrose,had significant influences on the paste properties.

Effect of hypoxia on growth and angiogenesis of lung carcinoma cells

China Medical Engineering (2005)

Liu Zhi-xia

Objective To realize the effect of hypoxia on the growth and angiogenesis non-small cell lung carcinoma. Methods Non-small cell Lung carc inoma cell (A549) were exposed to hypoxia(5%O2,5%CO2,90%N2) or anoxia(95%N2, 5%C O2) condition for 48 hours. The cells exposed to hypoxia were planted under skin in nude mice, and observed the volume per 5 days. After 25 days, the weight and volume were measured, and the mirovessel density (MLD) were observed by immune tissue chemistry method for CD34, the level of vascular endothelial growth facto r (VEGF) and basic fibroblast growth factor (bFGF) were assayed by ELISA. Resu lts Comparing with normoxia group, the volume and weighty of tumor under skin of nude mice invasiveness were increased in hypoxic group, the MLD and the leve l of VEGF and bFGF in hypoxic group were higher than those in normoxia group. Th e volume, the weighty, MLD and the level of VEGF and bFGF in anoxic groups, were decreased contrast to normoxic groups. Conclusions Moderate hypoxia can up- regulated the expression of VEGF and bFGF, and increase the angiogenesis and gro wth of non-small cell lung carcinoma. But serious hypoxia can decrease the expre ssion of VEGF and bFGF, and inhibite the angiogenesis and growth of the carcinom a.

Effect of reduces agent dithiothreity(DTT) on viscosity properties of storage rice starch

Gansu Nongye Daxue xuebao (2009)

Liu Zhi-xia

The change of viscosity in storage milled rice was determined by adding reduce agent dithiothreity(DTT) with Rapid Visco Analyzer(RVA).The result showed that DTT decreased pasting temperatures of rice starch,while increased peak viscosity and breakdown viscosity.DTT reduced setback and changed the slopes of the linear parts of the curves for all samples.The addition of DTT to the cooking water decreased the hardness,increased the adhesiveness and improved eating and cooking quality of rice.

Application of near infrared transmittance spectroscoy(NITS)to the determination of viscosity setback of rice starch

Journal of Molecular Science (2009)

Liu Zhi-xia

One hundred and eighty-three samples of rice were scanned by Foss Tecator Infratec 1255,and their setback were determined by RVA(Rapid Visco Analyzer).Several mathematics treatments to the sample spectra and several different regressin methods were adopted to optimize a good calibration equation for determination of secback of rice.The standard error of calibration(SEC),standard error of cross-validation(SECV) and regression squared(RSQ) of the calibration selected were18.69,19.08 and 0.949 7.The NITS method has high accuracy in predicted tests of cross validation and independent validation.The method will offer a new approach of testing viscosity properties of rice starch with quick,precise and non-destructive characters.
