Caseous lymphadenitis (CL) is a chronic infectious disease caused by Corynebacterium pseudotuberculosis (C. pseudotuberculosis) that is transmitted mainly by contact with contaminated exudate wounds. Caseous lymphadenitis affects different species of animals and is considered an occupational zoonotic disease. CL is responsible for important economic losses in the small ruminant industry, which include decreased production, damaged quality of milk and wool, reproductive disorders, total or partial confiscation of carcasses, and depreciation of the skin. Caseous lymphadenitis disease can present in two clinical pictures: a skin or superficial picture and a visceral or deep picture. The presumptive diagnosis of CL in the skin is based on the exploration of superficial lymph nodes. These have little value in diagnosing visceral CL, where the main sign is emaciation. The prevention and control of CL involve identifying the skin condition and debriding the abscesses. In addition to the treatment of superficial lesions, the animal facilities must be repaired and adapted. To avoid exposure of negative herds to CL, new animals must be subjected to observation to identify any of the clinical manifestations. Another form of control is vaccination, though only some countries have commercial vaccines. General information on the etiological agent and its characteristics can be used to improve the understanding of this disease.

The recent rapid development of China’s foreign trade has led to the significant increase in waterway transportation and automated container ports. Automated terminals can significantly improve the loading and unloading efficiency of container terminals. These terminals can also increase the port’s transportation volume while ensuring the quality of cargo loading and unloading, which has become an inevitable trend in the future development of ports. However, the continuous growth of the port’s transportation volume has increased the horizontal transportation pressure on the automated terminal, and the problems of route conflicts and road locks faced by automated guided vehicles (AGV) have become increasingly prominent. Accordingly, this work takes Xiamen Yuanhai automated container terminal as an example. This work focuses on analyzing the interference problem of path conflict in its horizontal transportation AGV scheduling. Results show that path conflict, the most prominent interference factor, will cause AGV scheduling to be unable to execute the original plan. Consequently, the disruption management was used to establish a disturbance recovery model, and the Dijkstra algorithm for combining with time windows is adopted to plan a conflict-free path. Based on the comparison with the rescheduling method, the research obtains that the deviation of the transportation path and the deviation degree of the transportation path under the disruption management method are much lower than those of the rescheduling method. The transportation path deviation degree of the disruption management method is only 5.56%. Meanwhile, the deviation degree of the transportation path under the rescheduling method is 44.44%.

太平洋战争期间的侨生救济与中英关系

太平洋战争爆发后,部分港大学生(侨生)内撤中国大后方。英国由救济这批港大学生开始,试图扩大救济中国境内所有英属地侨生,却遭到国民政府反对。英国从帝国视野出发,希望维持其对大英帝国臣民的管辖权;中国则坚持侨生为中国国民,理应由中国政府予以救济。中英围绕侨生救济权的争夺主要发生在1943年。这一过程既折射中英新约签署前后治外法权问题在实践层面的新变化,也体现国民政府欲借侨民救济彰显中国主权和大国地位。由此侨民问题将抗战与反帝反殖联系在一起。侨生争取中英两国救济的能动性,展现他们作为侨民、难民和学生的跨域经历,勾连二战中港大与大后方一段共同历史,也启发我们从侨民维度重新思考百年来中英不平等关系。

阿尔弗雷德·希区柯克(1899-1980),被称为“悬念大师”[1],也被称为电影界的弗洛伊德,心理分析大师。他擅长利用情节、声音与画面制造引人入胜的悬疑,也擅长探入人物的潜意识领域,甚至直面、解剖人类各种精神疾病,塑造复杂立体的人物。因此从电影研究的角度看,希区柯克的电影绝对是精神分析、符号学分析等理论的较好研究文本,是一些新潮理论家乐于实践操练的电影批评的重要园地。许多重要的解读文章成为了电影精神分析的范本。

为探究大水面养殖与池塘养殖模式下鱼类肌肉品质可能存在的差异及其原因,以鳙(Hypophthalmichthys nobilis)为研究对象,采集并观测湖北省网湖(网湖放养组)和周边养殖池塘(池塘养殖组)两组鳙的背部肌肉的表观、质构、营养和风味等特征,并对两者的水质条件与饵料生物组成进行对比研究。结果显示:(1)网湖放养鳙的腹脂比(IPF)、肝体比(HSI)显著低于池塘养殖组(P0.05);网湖放养鳙的背部鱼皮和背部鱼肉的亮度值(L*)和白度值(W)显著高于池塘养殖组(P0.05),硬度显著低于池塘养殖组(P0.05);(4)网湖放养组的鲜味氨基酸占比更高,苦味氨基酸占比更低;网湖放养组和池塘养殖组的最高气味活度值分别是呈青草味的己醛和油脂味的1-辛醛,对气味呈负面影响的1-己醇、3-戊酮等挥发性化合物含量及相对气味活度值(ROAV)在网湖放养组更低。研究结果表明,网湖放养鳙相对于池塘养殖组具有更好的形态特征、肌肉营养和风味品质,这与其养殖环境和天然饵料的差异有关。本研究可为大水面生态渔业的发展提供理论参考。
