RESERVOIR CHARACTERISTICS OF JURASSIC SHAXIMIAO FORMATION,WESTERN SICHUAN BASIN

Our study shows that （ 1 ） the Shaximiao reservoir, western Sichuan Basin, is mainly composed of arkose and lithic ar- kose, and litharenite, feldsparthic and lithic quartz sandstone for the second; （2） the reservoir space includes pore and fracture, and in- tergranular dissolution pore for the main one whereas residual intergranular pore and intragranular dissolution pore for the second ones; （3） the throat type dominantly contains tubular and intergranular fissures, which belong to fine- to micro-throat ones; （4） its porous structure is poor, which is characterized by small pore and shallow throat, small volume of effectively connecting pore, and medium to high drainage pressure; and （5） this reservoir is mostly featured by low to medium porosity and permeability, partly high porosity and per- meability, and strong heterogeneity. In addition, the factors controlling its growth, the sandbedy distribution, and the favorable reservoir belts are further studied. These results may provide an important support for exploration and development of Shaximiao reservoir.     

Sourcing performance satisfaction: A study of the critical success factors and firm-related characteristics

Abstract

The aim of this paper is to identify the critical success factors (CSFs) of production sourcing for small and medium-sized clothing firms in Hong Kong, and to explore the effects of these factors and firm-related characteristics on satisfaction with production sourcing performance. A two-stage methodology was applied. In the first stage, a multiple-case study of ten small and medium-sized clothing firms in Hong Kong was undertaken to identify the CSFs and critical performance indicators of production sourcing. In the second stage, a questionnaire-based survey was conducted among 104 small and medium-sized clothing firms to test the developed hypotheses. Based on the findings, the two most significant success factors of production sourcing are the sustaining of long-term relationships with production providers and choosing production providers carefully. The two aspects of production sourcing performance that are most likely to lead to satisfaction are on-time delivery and better quality. The results show that the level of satisfaction with sourcing performance is influenced by certain CSFs and firm-related characteristics.

Turkey liver: Physicochemical characteristics and functional properties of protein fractions

Turkey liver is an important edible meat by-product. However, it is generally unprocessed, underutilized and low-priced compared to mammalian livers. The present investigation was conducted to provide information on physicochemical composition and functional characteristics of turkey liver. Proximate composition (%) was: moisture (72.3 ± 1.2), protein (21.9 ± 0.6), fat (2.9 ± 1.6), carbohydrate (1.4 ± 0.7), and total ash (1.5 ± 0.1). Cholesterol, glycogen and total heme pigments (g/kg) in the turkey liver were 2.05 ± 0.06, 5.36 ± 0.01 and 2.3 ± 0.08, respectively. Contents in saturated, monounsaturated and polyunsaturated fatty acids (%) were 42.5, 14.6 and 32.6 respectively. Interestingly, turkey liver fat also contains 5% of camphor (oxygenated monoterpene). Mineral concentrations (mg/kg) in liver were: Na (817 ± 14), K (1390 ± 90), Ca (31.4 ± 0.3), Mg (23 ± 0.4), Fe (161 ± 5), Zn (40 ± 2) and Cu (34 ± 2). Liver proteins extracted at 5 or 10 g/l NaCl showed the highest foaming capacity (P < 0.05). Addition of xanthan (1-3 g/l) to liver proteins improved both foam formation and its stability (P < 0.05). Turkey liver also showed interesting emulsifying properties. The emulsion stability of liver proteins was more pronounced at high NaCl concentration (20 g/l). The highest emulsion stability was obtained at acidic or basic pH values (P < 0.05) and decreased at pH 6.

Evaluation of various salt levels and different dairy proteins in combination with microbial transglutaminase on the quality characteristics of restructured pork ham

The objective of this study was to evaluate the quality characteristics of restructured pork hams (RH) manufactured with various salt levels (0.5%, 1.0%, and 1.5%) and different dairy proteins (sodium caseinate, SC and whey protein isolate, WPI; 1.0%) in combination with microbial transglutaminase (MTGase; 0.3%). Reduced‐salt (0.5% and 1.0%) RH resulted in reductions of moisture contents (%), textural springiness, cooking yield and most sensory preferences (P < 0.05). When dairy proteins in combination with MTGase were incorporated into the manufacture of RH, SC with MTGase was shown to reduce cooking loss (CL, %) and to increase the textural springiness and chewiness of RH, whereas WPI with MTGase increased textural springiness and chewiness, as well as the shear value of RH (P < 0.05). On the contrary, MTGase with dairy proteins improved the sensory preferences of reduced‐salt (1.0%) RH to give it similar sensory properties to those of the regular‐salt (1.5%) RH controls (CTL) (P > 0.05). The findings of this study demonstrated that the combination of 1.0% dairy proteins and 0.3% MTGase could affect improvements in the functional, textural and sensory properties of reduced‐salt (1.0%) RH.     

制备非晶薄带冷却辊流动换热特性及协同优化

为改善平面流铸冷却辊的换热特性,提高Fe-Si-B非晶薄带的横向厚度均匀性,建立了冷却辊轴向换热通道数值计算模型。在分析现有通道流动换热特性基础上,提出一种球面形换热通道设计方法。基于场协同理论,综合换热与流阻,对所提球面形通道进行优化,并进行实验验证。结果表明:通道内冷却水换热效率沿水流方向逐渐下降,与冷却辊换热主要发生在靠近冷却辊内壁位置,现有冷却辊宽度中部温度远大于两端,轴向温差明显;球面形通道可以加强冷却辊中部换热,降低外壁温度、热变形和轴向变形差,进而改善非晶薄带横向厚度均匀性;随着球面半径的减小,通道中部换热明显增强,但流阻随之急剧增大;综合流阻与换热特性,存在最优通道优化半径。     

Design and simulation of a novel GaN based resonant tunneling high electron mobility transistor on a silicon substrate

For the first time, we have introduced a novel GaN based resonant tunneling high electron mobility transistor (RTHEMT) on a silicon substrate. A monolithically integrated GaN based inverted high electron mobility transistor (HEMT) and a resonant tunneling diode (RTD) are designed and simulated using the ATLAS simulator and MATLAB in this study. The 10% Al composition in the barrier layer of the GaN based RTD structure provides a peak-to-valley current ratio of 2.66 which controls the GaN based HEMT performance. Thus the results indicate an improvement in the current-voltage characteristics of the RTHEMT by controlling the gate voltage in this structure. The introduction of silicon as a substrate is a unique step taken by us for this type of RTHEMT structure.
