Host–parasite interactions in closed and open microbial cultivation system

The study addresses interaction of bacteria and phages in the host–parasite system in batch and continuous cultures. The study system consists of the auxotrophic strain of Brevibacterium – Brevibacterium sp. 22L – and the bacteriophage of Brevibacterium sp., isolated from the soil by the enrichment method.

Closed system. In the investigation of the relationship between the time of bacterial lysis and multiplicity of phage infection it has been found that at a lower phage amount per cell it takes a longer time for the lysis of the culture to become discernible. Another important factor determining cytolysis in liquid medium is the physiological state of bacterial population. Specific growth rate of bacteria at the moment of phage infection has been chosen as an indicator of the physiological state of bacteria. It has been shown that the shortest latent period and the largest output of the phage are observed during the logarithmic growth phase of bacteria grown under favorable nutrient conditions. In the stationary phase, bacterial cells become “a bad host” for the phage, whose reproduction rate decreases, and the lysis either slows down significantly or does not occur at all.     

名城文化误区与政府文化观

当前历史名城的保护和建设中,出现了不少文化误区,表现为“泛文化”、“狭文化”、“假文化”、“死文化”、“功利文化”以及文化的“泛产业化”和非特色化,等等。产生这些误区的原因不仅仅是政府利益和政绩观、发展观产生偏差,政府文化观的缺失与错位才是问题产生的根源,因此,只有培养正确的文化观和体制改革双管齐下,才能更好地保护和传承名城文化,避免借保护之名行破坏之实的行为。     

管理中的中国古代人性观和西方人性假设

人性假设理论是管理理论的深层次结构,是管理理论的基础,对管理思想和制度等产生了重大影响.不同的人性假设理论导致不同的管理思想,这些人性假设理论不仅包括中国古代性善论、性恶论及二者的折衷,也包括西方经济人、社会人、自我实现人人性假设理论,等等.中西方人性假设之间不仅有一定一致性,也存在着诸如社会背景、产生方式、结构模式等的差异.

论中国现代文学的经典化——以鲁迅和沈从文为例

中国现代文学的发展经历了萌芽与兴盛，发展与曲折，成熟与繁荣，铸就了一批具有权威性和超越时空的文学经典，中国现代文学也成为一种经典性的存在。所谓的经典，意味着这类作品或著作在经过历史的沉淀之后，拥有经久不衰的文学价值，闪烁出典范与权威的光芒，也最终成为了文学领域中的精英和精华。在对古代文学经典形成定论之后，随着社会的发展，白上个世纪九十年代，现当代文学作家作品也面临着经典化的问题。文章基于对文学经典的理解，针对中国现当代文学，主要以现代文学中的典型作家作品为例来探讨中国现代文学的经典化。

Silkworms culture as a source of protein for humans in space

This paper focuses on the problem about a configuration with complete nutrition for humans in a Controlled Ecological Life Support System (CELSS) applied in the spacebases. The possibility of feeding silkworms to provide edible animal protein with high quality for taikonauts during long-term spaceflights and lunar-based missions was investigated from several aspects, including the nutrition structure of silkworms, feeding method, processing methods, feeding equipment, growing conditions and the influences on the space environmental condition changes caused by the silkworms. The originally inedible silk is also regarded as a protein source. A possible process of edible silk protein was brought forward in this paper. After being processed, the silk can be converted to edible protein for humans. The conclusion provides a promising approach to solving the protein supply problem for the taikonauts living in space during an extended exploration period.
