笔者认为苔丝、爱玛、安娜“自杀”主要有三个方面的原因:首先,对爱情的绝望是她们自杀的最直接原因;其次,她们自身带着沉重的罪恶感。一方面想从现实环境中逃脱出来,一方面又无法摆脱既定的社会法则;最后,她们都生活在转型时期比较混乱的社会环境中,各种社会因素交织成一张巨网,使她们围困其中而无法动弹。 相似文献

Physical aspects of external beam abdominal radiotherapy are discussed. Acute, intermediate, and late radiation effects on tissue are reviewed as a basis for determining abdominal organ tolerance to therapeutic radiation. Specific tolerances of critical organs that may be affected by abdominal radiotherapy are itemized, and the manifestations of intolerance are described. Potential application of abdominal radiotherapy to veterinary medicine is proposed. Data available on management of adverse reactions to abdominal radiotherapy are summarized. 相似文献

Pans are isolated, shallow depressions that are endorheic in nature. Because of the natural hydrological functioning of pans, these systems are usually restricted to arid regions and complete desiccation occurs seasonally. In the eastern provinces of South Africa many pans are perennial in nature often remaining inundated for several years. A study of the aquatic invertebrate community structure of selected perennial pans indicated that when these systems undergo complete desiccation, the communities are comparable to the communities of ephemeral ecosystems. During these periods the community displays normal succession patterns with branchiopod crustacean dominating the community structure a few weeks after inundation. These perennial ecosystems are comparable to similar habitats around the world but are under increasing threat due to an increase in mining and agricultural activities within the study area. 相似文献

A questionnaire-based survey was conducted in small-scale pig farms in the rain forest of the Colombian Pacific coast in order to study aspects of reproduction, nutrition and productivity. A total of 124 farmers was interviewed. They owned, on average, 13.6 pigs, including 2.3 sows, mainly of the Zungo breed. Pigs are reared in extensive systems and are allowed to wander freely in search of food. The sows produce, on average, 9.6 piglets/litter but, owing to poor sanitary conditions, 1.5 are born dead and only 6.3 are weaned alive. Two-thirds of the sows have five litters or more and the boars are also kept for a long time. This leads to high consanguinity rates within the herd and low productivity. Diets are based on maize, banana, tubers (taro, cassava) and fruits (peach palm, among others), and are rich in energy but poor in protein and minerals. The lack of protein and mineral sources appears to be the main limiting factor of these extensive production systems. Tree forages could partially solve the problem but are used by only 2% of the farmers. It is concluded that decreasing inbreeding, better piglet management and provision of balanced diets are areas that require immediate improvement. 相似文献

In different parts of Europe animal production is highly concentrated. Pig production generally is the main animal production activity in these areas. Main concerns of these large numbers of pigs are the amount of surplus nutrients in excreta and gaseous losses to the environment. Main nutrients of concern are N, P, and heavy metals and main gaseous losses of concern are ammonia, odour, and methane. Although losses are inevitable to a certain extent, nutrition seems to be a key factor in reducing these losses. Main nutritional strategies to reduce N and P excretions from pigs are: phase feeding (N, P), supplementation of limiting amino acids to the diet (N), and addition of phytase to the diet (P). Nutritional strategies to reduce heavy metals excretions from pigs are: finding alternative, natural, growth promoters that could replace Cu and Zn in the diet; using feedstuffs for the diet that are less contaminated with Cd. Main strategies to reduce ammonia emissions are: 1) lowering crude protein intake in combination with addition of limiting amino acids; 2) Shifting nitrogen excretion from urine to faeces by including fermentable carbohydrates in the diet; 3) lowering pH of urine by adding acidifying salts to the diet; 4) lowering the pH of faeces by inclusion of fermentable carbohydrates in the diet. These strategies proved to be independent from each other and effects are additive. By combining these strategies a total reduction of ammonia emission in growing-finishing pigs of 70% could be reached. Strategies to reduce odour emission are: 1) reducing protein fermentation by balancing available protein and fermentable carbohydrates in the large intestine; 2) Minimizing breakdown of absorbed sulphur amino acids. More studies are needed in this area of research, but results until now are very promising. A clear relationship exists between fermentable carbohydrates in the diet and methane emissions. This disadvantage should be considered when tackling ammonia emission by this strategy. It is concluded that there is a large potential to reduce environmental load within pig dense areas by nutritional means. 相似文献

Genetic selection and management changes during the last decades have significantly increased the average litter size of sows. However, this recent success has not correlated with an extension of longevity and reduction in replacement rate. Longevity or lifetime production of sows is determined by a combination of environmental and genetic factors. Nutrition is an environmental factor of importance, and it has long been appreciated that animals fed with specific diets may perform differently. The advent of modern science revealed that this is partly due to the ability of nutrients to act as signalling molecules that, through appropriate intracellular sensing mechanisms, can control gene expression and modulate cell functions. Based on this concept, nutrigenomics studies now aim to show that not only are certain nutrients essential for general health, but also that specific quantities of precise nutrients are necessary during critical periods of energy deficiency and oxidative stress such as gestation and lactation to ensure long‐term productivity. The toxic molecules at the origin of oxidative stress, free radicals, are mainly generated as normal by‐products of aerobic energy production by mitochondria. In all cells, mitochondria are dynamic organelles that are mainly known as the primary energy‐generating system. Thus, when metabolic demands are elevated as it is for hyperprolific sows, mitochondria are heavily solicited for answering all energetic needs, and substantive amounts of free radicals are generated. As a result, optimal conditions in term of antioxidant protection and metabolic substrates availability are required to support mitochondrial function in these animals. This article discusses how performance and longevity of sows are linked to mitochondrial function and oxidative stress and reviews the major natural nutrients known for their antioxidant and/or energetic properties that are susceptible to impact mitochondria and likely improved sows productivity. 相似文献
