Tomato brown rugose fruit disease: current distribution,knowledge and future prospects

Tomato is the most economically important fruit/vegetable crop grown worldwide. However, viral diseases remain an important factor limiting its productivity, with estimated quantitative and qualitative yield losses in tomato crops often reaching up to 100%. Many viruses infecting tomato have been reported, while new viral diseases have also emerged. The climatic changes the world is experiencing can be a contributing factor to the successful spread of newly emerging viruses, as well as the establishment of disease in areas that were previously either unfavourable or where the disease was absent. Because antiviral products are not available, strategies to mitigate viral diseases rely on genetic resistance/tolerance to infection, control of vectors, improvement in crop hygiene, roguing of infected plants and seed certification. Tomato brown rugose fruit virus (ToBRFV) is an emerging viral threat to tomato productivity and is currently spreading into new areas, which is of great concern to the growing global production in the absence of mitigation measures. This review presents the current knowledge about ToBRFV and future prospects for an improved understanding of the virus, which will be needed to support effective control and mitigation of the impact it is likely to cause.     

Measuring fish catch and consumption: Practical methods for small‐scale fisheries based on length as an alternative to weight‐based approaches

Small‐scale fisheries are recognised as making important contributions to nutrition and economic development despite a lack of accurate quantitative information on catches and consumption. While direct measurement remains the most appropriate way of collecting such data, it is impractical at large scales. Instead, household surveys based upon informant recall of fish caught and/or consumed are frequently used. However, the accuracy of weight recall by informants (even over short recall periods) has not been established. Using data from household surveys, the accuracy and precision of catch and consumption estimates derived from: (a) asking informants to recall weights of fish caught and (b) asking respondents to recall lengths of fish caught and converting to weight were tested. Length‐based methods, using visual aids to assist recall, were more accurate, precise and correctable. These methods could be useful for catch estimation, especially where fish are processed, sold or consumed shortly after capture.     

拖拉机动量飞轮主动防侧翻控制与模型试验研究

针对拖拉机侧翻致死致伤事故仍时有发生的问题，基于旋转刚体加速时的反向施矩原理，以反作用动量飞轮为执行元件，提出了从主动安全角度解决拖拉机侧翻问题的研究方法。通过构建拖拉机动力学系统数学模型，解析了整机侧翻行为的动态演变机理。为保证拖拉机主体结构的完整性，将动量飞轮置于拖拉机前部，取代传统静态配重的同时可主动提供防侧翻力矩。应用Matlab/Simulink软件，对反作用飞轮的回稳过程进行了基于PID控制的有效性仿真分析，同时设计并搭建了比例模型试验平台，对主动施矩飞轮的回稳控制效果进行了试验验证。结果表明，装备飞轮的拖拉机与无控制组对比，在一次试验中可多次实现整机的防侧翻控制，使整机防侧翻性能得到明显改善，且不同行驶工况下的试验数据与仿真结果的相关性较强，充分验证了本文拖拉机侧翻动力学模型的有效性。     

低温等离子体活性水在食品领域的应用进展

低温等离子体活性水（Plasma-activated Water，PAW）中富含活性氧（ROS）、活性氮（RNS）等活性成分，并具有低pH、高氧化还原电位、高电导率等特殊理化性质，近年来逐渐成为一种新型的非热物理加工方式被应用到食品杀菌与保鲜领域。低温等离子体活性水不仅能有效杀灭食品中的微生物，包括细菌、酵母、霉菌等，还能维持食品本身的品质不受显著性破坏，并且具有操作简单、处理时间短、效率高等优点，可以广泛应用在于果蔬和水产品的保鲜及肉制品的加工工艺中，满足目前市场对绿色无公害的产品需求。本文综述了低温等离子体活性水在食品领域的应用进展，讨论了低温等离子体活性水对微生物的灭活机理、对食品营养品质和感官特性的影响及PAW目前的局限性和未来发展潜力。     

水流作用下临水岸坡稳定性计算模型

河流崩岸是我国堤防安全面临的重大问题,汛期前后崩岸诱发大量的滑体进入河道,影响航运,给沿岸人民正常生产生活带来重大影响。针对水流作用下临水岸坡失稳问题,综合考虑坡表静水压力、内部孔隙水压力、边坡几何形状等因素的影响,构建了楔形岸坡稳定计算模型,并结合长江干流芙蓉大堤段崩岸实例,分析了各因素对岸坡稳定的作用。结果表明,坡表与地下水位升降及二者之差,对岸坡稳定影响较大,且水流的淘刷深度也直接影响着岸坡整体稳定。
