为探明花后弱光胁迫对软质小麦籽粒产量、淀粉粒度分布及黏度参数的影响,以软质小麦品种荃麦725和扬麦15为材料,在小麦开花后设置3个弱光处理即S1 (遮光10%)、S2(遮光20%)、S3(遮光30%)处理,以自然光照条件为对照,分析花后不同程度弱光条件下软质小麦籽粒产量、淀粉粒度分布与黏度参数的差异。结果表明,与对照相比,花后弱光降低了小麦粒重、穗粒数和产量,提高了籽粒蛋白质含量,但使籽粒淀粉含量、籽粒蛋白质和淀粉积累量显著减少。花后弱光降低了软质小麦B型淀粉粒(粒径≤10μm)体积、表面积百分比,增加了A型淀粉粒(粒径>10μm)体积、表面积百分比,对A、B型淀粉粒数目百分比无显著影响。在B型淀粉粒中,弱光对粒径0.1～2.8μm的淀粉粒体积百分比的影响较粒径2.8～10μm的淀粉粒大。在A型淀粉粒中,弱光对粒径>22μm的淀粉粒体积百分比的影响大于粒径10～22μm的淀粉粒。弱光导致小麦籽粒淀粉峰值黏度、低谷黏度、最终黏度、稀懈值、回升值等参数显著下降。花后弱光虽然可增加软质小麦籽粒蛋白质含量,但显著降低籽粒淀粉含量以及蛋白质和淀粉积累量,不利于粒重与产量形成;弱光对B型淀粉粒的影响大于A型淀粉粒,会降低B型淀粉粒体积和表面积占比,但可增加A型淀粉粒体积和表面积占比,降低淀粉峰值黏度等参数。

This paper presents the results of comprehensive laboratory experiments to investigate the effects of hooked-collar on the scour development around a vertical pier with a lenticular cross section. The flow around the pier was uniform, steady, and under the clear-water condition. The axial scour profiles for cases without and with a lenticular hooked-collar were measured and the effects of hooked-collar dimensions and elevation from the bed were examined. To compute the efficiency of hooked-collar for scour prevention, the results of local scour for a bridge pier without a collar and a bridge pier with a plain collar, without a hooked wall, were used as benchmark data sets. A wide range of hooked-collar geometries such as the ratio of collar width to the pier width, Wc/Wp, ranging from 1.5 to 3.5, the ratio of hooked-collar wall height to the pier width, Hc/Wp, ranging from 0.15 to 0.6, and the ratio of collar elevation to the pier width, Ec/Wp, of-0.5, 0, and 0.5 were tested. The experimental results indicated that the equilibrium scour depth decreased with the ratio of hooked-collar to the pier width when Wcis twice the pier width, Wp. For Wc/Wp> 2, the scour depth was similar to the tests with an infinitely large pier width. In addition, the scour depth consistently reduced as the hooked-collar wall height, Hc, to the pier width, Wp, approached 0.3. The highest scour reduction efficiency was achieved when the hooked-collar being placed on the bed surface. Empirical models were developed for prediction of maximum scour depth near the lenticular bridge pier with a modified collar. The results showed that the volume of scour hole around a lenticular pier increased non-linearly with the maximum scour depth and it was independent of the hooked-collar geometry.

Arsenic(As) in natural hydrological systems is known as a worldwide major environmental concern. A geochemical and sedimentological study was done to ascertain the origin and geographical distribution of As in surface water and fluvial sediment collected from the floodplains/basins of the River Indus and its four major tributaries that drain through the northern Pakistan. The hydrogeochemical compositions of all five rivers were similar with calcium(Ca2+) and bicarbonate(HCO3-) being the dominating ions. The concentration of As ranged from 0.62-24.05 μg/L(average 3.7 ± 3.5 μg/L, n = 61) in river water, 2.3-23.4 mg/kg(average 5.7 ± 3.9 mg/kg) in suspended sediment, and 2.0-13 mg/kg(average4.13 ± 2.3 mg/kg) in fluvial sediment. Various approaches were used, including mineralogical, sequential extraction, geochemical, and statistical analyses to investigate the distribution, behavior, and potential sources of As in the sediment. The effect of geological factors on the distribution of As was also *** noticeable changes in the relative abundance of minerals were observed in the sediment at different locations along the river. Both mineralogical and statistical analyses showed that silicate minerals like muscovite, biotite, and chloride are the main As reservoir while oxides minerals like hematite and magnetite, which are minor components in the sediment are second largest As carrier. A geochemical baseline, using the normalization and cumulative frequency distribution curves was constructed for *** estimated mean human contribution of As was 3.4% in the Indus River, 1.9% in the Jhelum River, 13.7%in the Chenab River, 17.5% in the Ravi River and 5.4% in the Sutlej River, indicating relatively higher effects of anthropogenic activity along the Chenab River and Ravi River. The almost negligible effects of anthropogenic activities were additionally confirmed through the pollution assessment parameters estimated from the geo-enrichment, contamination factors, and ac
