Textile Industry to See Slow Growth Analysis of industrial production activities in the first four months

Textile industry, a major driver of the Chinese economy, has fallen victim to the global credit crisis and weaker demand. In the first two months, the output, sale, investment and export of textile industry grew at a slower pace than last year. But things began to pick up after that as the economy slowly begins to recover since March. Signif icant gains at that time will be hard to come by, and won’t be nearly enough to prevent other sizeable slippage in overall textile and apparel activity.

THE EFFECT OF BASIC FIBROBLAST GROWTH FACTOR SLOW-RELEASE MICROCAPSULES ON ANGIOGENESIS IN INFARCTED RABBIT MYOCARDIUM

Objectives To observe the effect of basic fibroblast growth factor (bFGF) slow-release microcapsules on angiogenesis in infarcted myocardial regions. Methods.Myocardial infarction was induced in 24 New Zealand rabbits by ligating the root of left anterior descending coronary artery.Group Ⅰ(n=8) served as control, group Ⅱ(n=8) as a blank microcapsule group, group Ⅲ(n=8, each microcapsule contains 1μg bFGF) as micrpcapsule group.In group Ⅱ and Ⅲ, 5 blank microcapsules or bFGF slow-release microcapsules were implanted into myocardium underneath the epicardium between the left anterior descending coronary artery and left circumflex artery.Infarct size was evaluated by infarcted weight/left ventricle weight ratio and angiogenesis was evaluated by immunohistochemical examinations 5 weeks later. [WT5”BX] Results.As compared with group Ⅰ and Ⅱ, rabbits treated with bFGF slow-release microcapsules showed higher microvessel counts (group Ⅰ3775±450, group Ⅱ3837±498,vs.group Ⅲ 13550±481,P<0001) and less infarcted weight /left ventricle weight (group Ⅰ168%±04%,group Ⅱ167%±05%,vs.group Ⅲ 70%±02%,P<0001). Conclusions.Subepicardial administration of bFGF slow-release microcapsule in the infarcted rabbit model results in effective angiogenesis and reduction in infarct size.

Modeling and numerical investigation of slow crack growth and crack arrest in ceramic polycrystals

ntergranular slow crack growth in zirconia polycrystal is described with a cohesive zone model that simulate mechanically the reaction-rupture mechanism underlying stress and environ- mentally assisted failure. A 2D polycrystal is considered with cohesive surfaces inserted along the grain boundaries. The anisotropic elastic modulus and grain-to-grain misorientation are accounted for together with an initial stress state related to the processing. A minimum load threshold is shown to originate from the onset of the reaction-rupture mechanism to proceed where a minimum traction is reached locally and from the magnitude of the initial compression stresses. This work aims at providing reliable predictions in long lasting applications of ceramics.

Mn^(2+)掺杂Cs_(3)Cu_(2)I_(5)微晶的温和、快速溶液法合成

在铜基金属卤化物Cs_(3)Cu_(2)I_(5)中掺杂Mn^(2+)是拓宽发光范围的重要途径,但是已报道的掺杂方法大多需要高温、惰性气氛、较长时间和专用设备等。本工作将CsI固体粉末直接投加至CuI和MnCl_(2)的氢碘酸溶液中,在较低温度(60℃)、空气条件下快速(3 min)合成Mn^(2+)掺杂Cs_(3)Cu_(2)I_(5)微晶,并测试了其结构和发光性能。通过系列对比实验,提出一种由反应物溶解度控制的“缓释生长-掺杂”机制,证实CsI固体粉末在高浓度氢碘酸中的缓慢溶解能够降低Cs_(3)Cu_(2)I_(5)晶体的生长速率,为Mn^(2+)的低温、可控掺杂提供有利的动力学条件。该方法为全无机金属卤化物体系的掺杂发光和掺杂动力学研究提供了新的思路。

Macroplastics on Soil-Plant System: Inhibiting Effects of Macroplastics on the Growth of Green Amaranth (<i>Amaranthus viridis</i>)

In recent time Bangladesh faces a serious problem of soil pollution due to plastic contamination. However, the degree of the extent to which the effects of plastics on plant growth occur is not properly identified. An experiment was conducted to measure the effects of mixed plastic (polyethylene and disposable plastic glass) on the growth of Amaranthus viridis. Different doses of mixed plastics (T0, T1, T2, and T3) were applied with a fixed amount of soil for each of the treatments e.g., T0 (control), T1 (10 gm mixed plastics/3kg soil), T2 (15 gm mixed plastics/3kg soil) and T3 (20 gm mixed plastic/3kg soil), and the growth response of Amaranthus viridis against plastic was observed for six consecutive weeks. The growth was measured in terms of plant height and girth diameter. The results showed that the presence of mixed plastic had a significant effect on the growth of Amaranthus viridis and particularly in treatment T3 (3 kg soil/20gm mixed plastic), the plants showed a slower growth response compared to control and the rest of the treatments applied in case of both plant height as well as girth diameter. The statistical analysis (one-way Analysis of Variance) also proved the significance of the treatments (p-values < 0.05) for six consecutive weeks. The experiment was successfully able to set an index on which plastics had their effects on the growth of green amaranth. In addition, the obtained data will be helpful in future research of the study in determining the possible effects of plastic on plant growth viz. green amaranth.

Mathematical modeling of the native Mexican turkey’s growth

Little is known about the productive performance of Mexican turkey, so the objective of the present study was to characterize growth performance curves of backyard turkey under a confined system. Forty fertile eggs were artificially incubated and turkey weight was recorded at hatch. During growth performance weekly weight was measured until 385 days of age. Turkey commercial feed and water were offered ad libitum. To characterize growth curves, a fourth degree polynomial model regression and a Richards biological model were used, which were compared by determination coefficient (r2), to reach the best fit model. The best fit model was the fourth degree polynomial regression model from a mathematical standpoint of view. It was found that maximum tom growth was reached at 15.7 weeks with a weight gain of 259.3 g/week and in hens at 12.4 weeks with a weight gain of 112.0 g/week. Body weight reached by toms at 40 weeks was 6 kg and hens at 35 weeks with 3.6 kg.

Effect of Temperature, pH and Water Activity on <i>Penicillium digitatum</i>Growth

Growth curves fitted Penicillium digitatum were used to analyze the effect of temperature, pH and aw on their growth. To asses observance of independent variable effects on all growth parameters (λ, latency time, μ, growth rate and ymax maximal growth) a slow growth strain of P. digitatum was employed. Growth curves were obtained at different conditions of temperature (10?C - 40?C), pH (3.0 - 7.0) and water activity (0.800 - 0.990) and growth parameters were calculated by fitting of logistic model. Polynomial models were made by linear regression and all terms (linear, quadratic and interactive effects) were statistically significant (p < 0.001). All growth parameters, including maximal growth were affected by environmental conditions;pH effect was more important on maximal growth than that on lag time or growth rate. In some aspects results and modeling behavior of P. digitatum, are very similar to modeling of bacterial growth.

Effects of Slow-release Fertilizers and Sugarcane-specific Fertilizers on Yield and Quality of Sugarcane

The effects of slow-release fertilizers and sugarcane-specific fertilizers on the growth and quality of sugarcane were studied to provide a theoretical basis for cultivation of sugarcane with lower costs but higher efficiency. Field experiments were carried out in two major sugarcane areas in Guangxi and three fertilization treatments were studied: single application of compound fertilizers( treatment I),compound fertilizers + slow-release fertilizers( treatment II) and sugarcane-specific base fertilizers + sugarcane-specific topdressing( treatment III). Effects of equal fertilization conditions of treatment I,II and III on growth,yield and sugar of sugarcane were studied. The three fertilization treatments had little effects on emergence,tillering,and effective stems of sugarcane,but compared with the treatment of compound fertilizer( treatment I) with a ratio of N,P,and K of 1∶1∶1,treatment II using slow-release fertilizers as topdressing had better growth,higher plant height and stem diameter,so the yield was higher. Treatment III designed sugarcane-specific fertilizers with proper ratio according to fertilizer demands of sugarcane. Besides,the treatment III sugarcane-specific base fertilizers,containing certain amount of organic matters,could promote the sugar accumulation of sugarcane. Therefore,the sugarcane yield of treatment III was higher than that of treatment II. In conclusion,slow-release fertilizers and sugarcane-specific fertilizers can significantly increase sugarcane yield,especially sugarcane-specific fertilizers. Sugarcane-specific fertilizers have reasonable ratio and contain certain amount of organic matters,and can increase sugar content,obtain significant economic benefits,so it is worth popularization in large areas.

Effect of Ammonium- and Potassium-Loaded Zeolite on Kale (<i>Brassica alboglabra</i>) Growth and Soil Property

We investigated the feasibility of using ammonium- and potassium-loaded zeolite (NK-Z) as carriers for fertilizer and for slow release of nitrogen (N) and potassium (K). Plant growth response and soil analysis were performed. The results indicated an increase in the total harvest weight of kale (Brassica alboglabra Bailey). Furthermore, higher levels of N and K were detected in soil applied with NK-Z than in soil applied with compound fertilizers. The leaf fresh weight of kale in the fertilizer treatments including NK-Z were 2118.4 and 2111.3 g·plant-1, while the leaf fresh weights of kale in the treatment without NK-Z was 2018.0 g·plant-1. The N and K contents in the soils were maintained in the high level in the NK-Z treatment compared that in control treatment. The results indicate that NK-Z has a great potential as the slow-release fertilizer reducing pollution by preventing leaching to the ground water.
