  • JOHN FOWLES’ CONTRIBUTION TO POSTMODERN LITERATURE

    The term of postmodernism suggests that the period came after modernism (since the 70-90ss of the 20th century). Postmodern texts are marked by the mixture of times, cultures, languages, real facts and fiction, the present and the past. Postmodern literature is presented by such key figures in English literature as John Fowels , Julian Barns, Doris Lessing, A.S. Byatt, Peter Ackroyd, G. Swift, etc. Out of them we have chosen John Fowels’ novels because of his originality, versatility and skill were nowhere more evident than in his most celebrated novels, among them “The Collector,” “The Magus” and “«The French Lieutenant’s Woman».” In “«The French Lieutenant’s Woman»,” for example, he combined the melodrama of a 19th-century Victorian novel with the sensibility of a 20th-century postmodern narrator, offering his readers two alternative endings from which to choose and at one point boldly inserting himself into the book as a character who accompanies the hero on a train to London. His teasing, multilayered fiction explored the tensions between free will and the constraints of society, even as it played with traditional novelistic conventions and challenged readers to find their own interpretations.

  • Determination of Appropriate Seed Rate and Row Spacing of Bread Wheat for Highlands of Guji Zone

    Wheat is one of the major staple crops in Ethiopia in terms of both production and consumption. Even though it is such an important cereal crops in Ethiopia, it is giving low yield due to many production constraints such as lack of improved varieties, poor agronomic practice (inappropriate seeding rate and row spacing), diseases, weeds and low soil fertility in Ethiopia in general and in Guji zone in particular. Therefore, field experiment was conducted during the 2015-2017 main cropping season at Bore and Ana sora to assess the effect of seeding rate and row spacing on yield components and yield of bread wheat; and to determine appropriate seeding rates row spacing for bread wheat. The experiment was laid out RCBD in a factorial arrangement with three replications using a wheat variety known as ‘Huluka’ as a test crop. The treatments consisted of four levels of seeding rate (100, 125, 150 and 175 kg ha-1) and four levels of row spacing (15, 20, 25 and 30 cm) consisting a total of 16 treatments. Analysis of the results revealed that all parameters were significantly (P

According to the actual background provided in this paper, it can be concluded that the minimum cost of this factory in a week of power failure is 1868443.7 yuan without charging. If the remaining 20% of the battery is taken into account, the minimum charge is 2575502.0 yuan. After obtaining the results, the sensitivity analysis was carried out to improve the practicability of the results.

  • Nutritional Value and Associated Potentials Risks of Seafood Consumption

    Seafood provides essential nutrients to the body. A study funded by CDC found that eating seafood for essential Omega-3 fatty acids can prevent 84,000 deaths each year [1-3]. According to a Harvard study, 3-ounce servings of fatty fish a week reduces the risk of dying from heart disease by nearly 40% [4]. Eating 8 two servings of fish per week during pregnancy can improve baby’s IQ, cognitive development, and eye health [5,6]. Older adults with the highest fish consumption live and average of 2.2 years longer [7]. But all these statements possess another side of the coin. Food-born poisoning, mercury-lead-arsenic-cadmium poisoning, exposure to polycyclic aromatic hydrocarbons (PAHs) raised the issue of safety with aberrant consumption of seafoods. Seafood choices that are very low in mercury include: salmon, sardines, pollock, flounders, cod, tilapia, shrimp, oysters, clams, scallops and crab. The U.S. Food and Drug Administration (FDA) and Environmental Protection Agency (EPA) have developed directions to help consumers minimize risks that could be associated with several pollutants (specially mercury) in seafood.

  • The Ultimate Strength of Ring Stiffened Cylindrical Shell and Its Influence Factors

    Calculating the modes of cylindrical shell, then embed them into ideal perfect cylindrical pressure-resistant shell as the initial geometric imperfections to form the modal. According to the characteristics of each mode, the first 30 modes can be classified into four types, and it is found that the mode of the first type is the worst defect form. By calculation, the cylinder shell has the minimum ultimate strength when the 23rd mode happened. The sensitivity analysis of cylindrical shells with initial geometric defects shows that the critical buckling load has approximate linear relationship with different thickness radius ratio and defect amplitude. Six cylindrical shells of different materials are selected for research, and it is found that although the modal orders of the worst geometric defects of various materials are not the same, they all belong to the first type of mode. The comparison showed that the 921 steel and 909 steel materials are economic.

  • Discussion on the Design of Cultural Commercial Complex—Taking a design of a cultural and commercial complex next to a university in Yichang as an example

    As the social economy develops faster and faster, the functions of commercial complex buildings become more and more diverse. It is not only a place to shop, but also a place to gather a place of popularity. Therefore, in addition to providing a shopping place, it also has the function of providing a gathering place for leisure and entertainment, and can become a landmark building of a city. Therefore, we hope that through the analysis of the design features of this work, a complete and detailed architectural design idea for the design of such commercial complexes can be proposed.

  • Evaluation of Fungicides with the combinations of Potato (Solanum tuberosum L.) Varieties to Manage Late Blight (Phytophthora infestans (Mont) de Bary) in Highlands of Guji Zone, Southern Ethiopia

    Potato late blight (Phytophthora infestans (Mont.) de Bary) is one of the most devastating plant diseases world-wide and is feared globally by farmers and industry. There is little information on the type of fungicide to be sprayed to control late blight for optimum production of the crop in the study area. Therefore, an experiment was conducted at Bore Agricultural Research Center, Southern Ethiopia during the 2015 and 2017 cropping season to evaluate fungicides with the combination of Potato varieties to manage late blight and to assess the cost and benefits of different fungicides on Gudanie and Jalenie potato varieties. The treatments consisted of two (2) Potato varieties Gudanie and Jalenie currently under production but differ in their late blight reaction and three (3) fungicides Ridomil Gold MZ 63.5%WP, Mancozeb 80% WP2 and Matico and one (1) unsprayed treatments were used as experimental materials. The experiment was laid out as a Randomized Complete Block Design (RCBD) in a 4 x 2 factorial arrangement and replicated three times per treatment. The improved potato varieties called Gudanie and Jalenie were planted as the test crop in a plot size of 3 m * 2.1 m with intra and inter-row spacing of 0.30 and 0.75 m respectively. Data were collected on growth, yield, yield components and disease incidence and severity. The two years combined data analysis results revealed that the interaction effect of fungicides and potato varieties had influenced significantly (P0.05) effect on days to50% emergency and average tuber weight. The two year data analysis the highest (47.34 t ha-1and 46.31 tha-1) marketable tuber yield was obtained from Gudanie variety with Ridomil Gold fungicide spraying at Bore on-station and Ana sora on-farm both locations respectively. The result of 2015 year disease data indicates that maximum (59.52% and 3.67) disease incidence and severity, respectively was…
