Outdoor Sports And Jack Wolfskin(II)

About Jack Wolfskin features

Jack Wolfskin’s head office is located in Idstein, Taunus, Germany. As the main brand in the European outdoor merchandise’s market and the largest distributor in the German sporting products’ retail industry, Jack Wolfskin’s success depends not only on excellent innovation ability, product concept based on quality and customer demand, but also on market-leading product lines and distribution strategies, including continuous investment in brand image.Click Here For More.

In recent years, Jack Wolfskin has begun to explore new potential customers after establishing a high brand awareness among outdoor sports enthusiasts. For example, the people who like outdoor feeling and like to go out in any weather but have not used outdoor goods frequently so far.

The basic principle of Jack Wolfskin’s products is to combine the best functionality with the highest comfort. We firmly believe that outdoor sports should be fun and products should help users get comfortable outdoor experience. The whole product line includes functional clothing, appliances and shoes specially designed for outdoor sports, tourism and leisure, which are divided into “outdoor mountain climbing”, “travel hiking”, “urban outdoor”, “leisure wild fun” and other series.

Jack Wolfskin has created the necessary preconditions for sustainable development. More experts joined Edstein Headquarters, and the quality of employees was strengthened. In the next few years, Jack Wolfskin will push ahead with plans to expand the European market and expand the Asian market.

Watching out, About Disadvantages of Steel Structure(II)

Steel as good heat resistance but poor fire resistance

With the increase of temperature, the properties of steel gradually change. When the temperature is less than 250 C, the mechanical properties of the steel change very little. When the temperature reaches 250 C, the steel has brittle turning (called blue brittleness), creep between 260 320 C, and then the strength decreases gradually. When the temperature reaches 450 C, the strength decreases sharply, and when the temperature reaches 650 C, the strength decreases almost to zero. Therefore, the steel structure has certain heat resistance, but poor fire resistance.Click Here For More.

Poor corrosion resistance of steel, protective measures so important

Steel is easy to be rusted, and it is easier to be rusted by chemical reaction or electrochemical action in wet or corrosive medium environment. Therefore, steel structure must be treated with anti-corrosion. Generally, steel components can be coated with anti-corrosive paint after rust removal, but this protection measure is not once and for all, and needs to be repaired at intervals, so its maintenance cost is higher. For steel members with strong corrosive media, coastal buildings and very thin wall thickness, special treatment should be carried out such as galvanized, galvalume composite layer, etc. These measures will correspondingly increase the cost of steel structures.

Brittle fracture about steel structures under low temperature or other harsh conditions

In the negative temperature environment, the plasticity and toughness of steel gradually decrease. When it reaches a certain temperature, the toughness will suddenly drop sharply. It is called cold brittleness at low temperature, and the corresponding temperature is called critical brittleness temperature. Low temperature cold brittleness is also one of the main causes of accidents in some steel structure projects in winter. In addition, steel is easy to brittle fracture under repeated loading, complex stress, sudden loading, cold working, aging hardening, welding defects and other harsh conditions.

 

School of Architecture, Tsinghua University(II)

College Faculties

As of June 5, 2011, the College has four departments: Department of Architecture, Department of Urban Planning, Department of Landscape Sciences and Department of Architectural Technology Science; 9 institutes: Institute of Architecture and Cities, Institute of Architectural Design, Institute of Architectural History and Cultural Relics, Institute of Housing and Community, Institute of Fine Arts, Institute of Landscape and Landscape Architecture, and Resources. The Institute of Conservation and Landscape Tourism, the Institute of Architectural Technology and the Institute of Architectural Environment and Equipment Engineering; as the base and external window of the College’s planning and design practice, there are Grade A Qualified Architectural Design Research Institute of Tsinghua University, Beijing Tsinghua Urban Planning and Design Institute and Andi Architectural Design Consulting Company. In addition, the human settlements research center of Tsinghua University and the building energy conservation research center of Tsinghua University are based on the construction college.Click Here For More.

Faculties’ Strength

By the end of 2012, there were 111 in-service teachers in the School of Architecture, Tsinghua University, including 44 professors, 54 associate professors, 13 lecturers and 46 postdoctoral students. Professors include academician of Chinese Academy of Sciences and academician of Chinese Academy of Engineering: Mr. Wu Liangyong (academician of both academies), Guan Zhaoyou, Mr. Li Daozheng and Jiang Yi. Five other academicians were employed as part-time professors.

Among the teachers, 50 have doctoral degrees, accounting for 48%, 54 have learning and working experience abroad, accounting for 52%. The overall quality of the faculty is good, the theoretical basis and basic skills are solid, teaching, teaching and teamwork are emphasized, and a rigorous and realistic teaching style has been formed. The faculty has constantly strengthened the vitality of reform and innovation. It provides a solid foundation for further improving the quality of teaching.

World’s longest cross-sea bridge with 5G According to Mr. Fang Zheng, vice general manager of the WLAN office of ZTE Corp, the bridge’s network operator, The Hong Kong-Zhuhai-Macao Bridge is the longest cross-sea bridge in the world and is expected to have 5G service in the not far future.Click Here For More. Fang said “The Hong Kong-Zhuhai-Macao bridge now has good coverage of 4G service,”Click Here For More.  he also added “Experts and workers have overcome the difficulties of a complex construction environment and the lack of an optical fiber to provide tailored 4G solutions for the bridge and prepare for the future upgrading of 5G service.” The 55-kilometre Hong Kong-Zhuhai-Macao Bridge opened last month connects the Mainland of Guangdong province with the two Special Administrative Regions of Hong Kong and Macao.Click Here For More. According to Mr Fang, Hong Kong-Zhuhai-Macau Bridge is now ready to enter the Internet of Things, which is a major business implemented by 5G technology. From the beginning, the technical foundation of 5G is considered in terms of network structure, 5G station building and optical fiber installation. Robot delivers the Post
