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.     

混凝土结构表面蜂窝麻面成因及其防治措施

随着建筑业的飞速发展和科技水平的不断提高,工程对混凝土的各种性能要求越来越高,不仅要求混凝土工作性能好、强度指标高、耐久性好等,而且还要求混凝土结构表面无蜂窝麻面光洁如镜的外观,尤其是清水混凝土结构要求更为严格,为此我们必须加以防范,给予重视。     

Long-term variation in brown trout, Salmo trutta L., stocking success in a large lake: interplay between availability of suitable prey and size at release

Abstract –  Factors affecting long-term variation in brown trout, Salmo trutta L., stocking success were examined in a large lake, Lake Oulujärvi, in central Finland. Brown trout were stocked in spring (late May to early June) in 1974–1991 and in summer (late June to early July) in 1992–2001. The biomass of the vendace, Coregonus albula (L.), population (prey) at release time had the largest positive effect on stocking success within both periods: biomass of adult vendace in spring and both 0+ and adult vendace in summer. Increasing the size of stocked fish had a positive effect if the vendace available at release were only adults. The increasing trend of predator-catch-per-unit-effort (CPUE) [combined CPUE of northern pike Esox lucius L., burbot Lota lota (L.), and pike-perch Stizostedion lucioperca (L.)] through the study period and its negative effect on trout stocking success suggested an increasing effect of predation within the entire time series.

大骨鸡中MSTN基因表达规律性的研究

本实验以大骨鸡为试材,采用RT-PCR法检测了MSTN基因在大骨鸡不同器官、不同时间的表达情况,结果表明MSTN基因在骨骼肌中表达水平较高,在心肌、肾脏、脑、肠、舌中也有微量表达,但在肺、肝脏中未检测出MSTNmRNA,而且在14日龄时表达水平明显低于35日龄和56日龄,而且在孵化后一周时胸肌中MSTN基因的表达水平达到最低。     

论法治与德治的辩证统一

法治既是一种治国方式和手段,也是人民行使管理国家、管理社会的权利的途径.德治的核心内容是要建立社会主义的道德体系和弘扬优秀的民族精神.法治和德治既有区别,又有联系,是辨证统一的.法治、德治的辩证统一是贯彻"三个代表"重要思想和建设中国特色社会主义的内在要求.     

关中西部四灌区旱情规律分析

为给关中西部灌区水资源合理调控提供依据，在简述干旱及其分类的基础上，指出了关中西部各类干旱多源于气象干旱。对该区7个气象站的年降水进行分析表明，各气象站年降水量的变差系数均为0．25，偏态系数均为0．5。以兴平气象站作为代表站对不同历时的旱情进行了分析，结果显示11月到来年2月发生重旱和特旱的概率较大，在30％左右，特别是12月份，概率达54％，且以特旱为主；7、8月份以中旱和重旱为主；夏玉米播前发生特旱的概率较高，达27％，拔节孕穗和抽穗开花期以特旱为主，概率达33％；冬小麦的越冬和麦黄期以特旱为主，发生概率在30％左右。
