全豆豆浆与传统豆浆感官品质和营养成分对比

以大豆为原料,通过感官评定对胶体磨技术自制的全豆豆浆和一般机械磨加工的传统豆浆中的永和豆浆和普通豆浆的感官品质进行了比较,通过营养成分检测对全豆豆浆和永和豆浆的营养成分进行了比较,同时将检测的全豆豆浆营养成分与中国食物成分表中的普通豆浆的营养成分进行比较。结果表明:全豆豆浆口感浓厚,细腻爽滑,豆香味浓郁,无豆腥味,感官评价总得分高于传统豆浆中的永和豆浆和普通豆浆,差异有统计学意义(P0.01);全豆豆浆中蛋白质、脂肪、总膳食纤维、维生素B1、维生素B2、钙、磷脂及大豆异黄酮等营养成分含量均高于永和豆浆,更高于普通豆浆。全豆豆浆的普及不仅可以提高豆浆的营养价值,还可以减少资源的浪费,具有一定的社会和经济效益。     

Detect unique molecular structure associated with physiochemical properties in CDC varieties of oat grain with unique nutrient traits [Feed Type vs. Milling Type] in comparison with barley grain using advanced molecular spectroscopy as a non-destructive biological tool

The objective of this study was to determinate grain unique protein inherent molecular structure that are related physiochemical and nutrient profiles in CDC developed oat varieties [CDC Nasser (Feed Type) and CDC Seabiscuit (Milling Type)] grown in cool climate condition in western Canada in comparison with conventional barley variety of CDC Meredith as a control using advanced molecular spectroscopy. Multivariate analyses, including an agglomerative hierarchical cluster analysis (CLA) and principal component analysis (PCA), were performed to identify protein molecular structural differences among the grains. The results revealed that CDC Seabiscuit contained greater (P < 0.05) protein structural Amide I and II than CDC Nasser and CDC Meredith, while the greater (P < 0.005) structural Amide I to II area and height ratios was detected in CDC Meredith. New oat grains had greater (P < 0.05) β-sheet height than barley grains, however, there was no difference in α-helix to β-sheet ratio values among the varieties. In conclusion, CDC Nasser and CDC Meredith had no difference in protein molecular structural features, while CDC Seabiscuit contains different protein structural characteristics as compared to CDC Meredith grain. The molecular structure features are highly associated with physiochemical and nutrient profiles in grains, which indicate that it also affect nutrient utilization and availability.     

校园环境噪声监测与评价--以华中师范大学为例

环境噪声是环境质量评价的重要指标。通过噪声监测实验,记录了华中师范大学校园内的噪声污染数据,根据国家标准评估了校园环境噪声状况。试验采用网络剖分法,分别于昼间7:30~10:00和夜间22:00~22:55两个时间段对等效声级进行了测定。实验结果表明:昼间噪声污染更为严重,平均噪声超标率达到26%,夜间噪声污染相对较轻,但噪声超标率也达到19%。校园内不同功能区的噪声来源不同,工程施工产生的噪声是主要的污染源,影响比重达到58%。根据实验结果,校园声环境质量一般,需要对现状提出合理的改进建议。     

Soil protection for a sustainable future: options for a soil monitoring network for Ireland

The increased recognition of the importance of soil is reflected in the UN Post‐2015 Development Agenda with sustainable development goals that directly and indirectly relate to soil quality and protection. Despite a lack of legally binding legislation for soil protection, the European Commission remains committed to the objective of soil protection. However, the achievement of a legally binding framework for soil protection relies on the implementation of a soil monitoring network (SMN) that can detect changes to soil quality over time. As beneficiaries do not pay for the provision of soil information, the options for soil monitoring are limited. The use of existing data sets should be considered first. Using Ireland as an example, this research explored the opportunities for a SMN for Ireland considering three existing national data sets. The options for a SMN are considered in terms of their spatial and stratified distribution, the parameters to be measured and an economic analysis of the options proposed. This research finds that for Ireland, either a 10 or a 16 km² grid interval stratified by land use and drainage class offers the best potential in relation to the spatial distribution of existing data sets to reflect local data at a national level. With existing data, the stratified SIS data using the 16 km² grid offers the best value for money, with baseline costs for analysis, excluding field costs, of between €706 481 and €2.8 million. Acknowledging the impossibility of measuring all parameters with ideal frequency, this study proposes a two‐tier system for optimized monitoring frequency. Parameters must anticipate future policy requirements. Finally, the implementation of a SMN must be accompanied by standardized methods, defined thresholds and action mandates to maintain soil quality within allowable limits.     

分子标记用于赤眼蜂分子监测的研究

通过对松毛虫赤眼蜂（Trichogramma dedrolimi Matsumura）以及玉米螟赤眼蜂（Trichogramma ostriniae Pang et Chen）rDNA-ITS2基因的克隆测序，并联机检索GenBank核酸序列库中其它赤眼蜂的相关序列，利用核酸分析软件找到松毛虫赤眼蜂和玉米螟赤眼蜂ITS2序列中一段有鉴别意义的标志，并据此设计出蜂种的特异PCR引物，实现了松毛虫赤眼蜂和玉米螟赤眼蜂rDNA特异区带的PCR扩增。研究表明该特异区带具有种的特异性。我们认为该分子标记技术可用于目前我国生防中常用的松毛虫赤眼蜂和玉米螟蒌眼蜂的分子监测，如田间种群动态监控和寄生效果评估。     

GI PiCO2: Tissue Specific Monitoring For Improving Patient Outcomes

Improvements in human patient monitoring despite their development in animals, do not always find their way into veterinary clinical use due to financial constraints. Gastrointestinal intraluminal CO₂ partial pressure (Gip₁CO₂) monitoring, however, is not only proving very beneficial in human trauma and critical patient care but is also very likely to become relatively inexpensive. By providing information on the perfusion adequacy of a high risk, critically important tissue, the GI mucosa, GI P₁CO₂ monitoring offers an easily accesible indicator of the efficacy and adequacy of resuscitative interventions. The potential for decreasing morbidity and mortality is enormous. Therefore, the practicing veterinarian should become familiar with GI P₁CO₂ monitoring theory and technology so he or she can be better prepared to incorporate it into practice when in becomes available.
