Modern Architecture: A Very Short Introduction explores the technical innovations that opened up the cultural and intellectual opportunities for modern architecture to happen. It shows how the invention of steel and reinforced concrete radically altered possibilities for shaping buildings, transforming what architects were able to imagine, as did new systems for air-conditioning and lighting. Focusing on a selection of modern buildings that also symbolize bigger cultural ideas, this VSI discusses what modern architecture was like, why it was like that, and how it was imagined. It also demonstrates how modern architecture owes much to the work of some of the historians and critics who helped to shape the field.

Many global cultures have traditions of clay or mud brick construction. Evidence exists of fired brick being used as long ago as 5000 bce in Mesopotamia. The role of brick in modern architecture differed to those of the technical innovations of iron, steel, and reinforced concrete. The adoption of brick represented instead a challenge to the hard-line view of modernity as a rejection of history, understanding modern architecture as a continuation of history. ‘Brick’ discusses the concepts of local and national architectures and critical regionalism, highlighting the monumentality and order of the work of Louis Kahn, including one of his last projects, the Indian Institute of Management in Ahmedabad.

Purpose of work is a compilation of data about the microflora which colonizes a split-system, with the aim of selection of sanitary-indicative microorganisms, whose presence in the sample would indicate to the need for cleaning and disinfection of split-systems. Materials and methods. In the article there were used data of five years author’s scientific inquiry, related to the prevention of respiratory diseases, associated with the usage of a local air conditioning systems. We also use the data from the literature. Results. For selection of “indicative” microorganisms, we proposed the usage of nine criteria, each of them have numeric value from 0 to 3 points (risk for health, prevalence rate of the disease, epidemiological link, speed of split system’s colonization, difficulty of cultivation, resistance in the environment, resistance to disinfectants, frequency of detection in home air conditioning systems, frequency of detection in air conditioning systems of public buildings). After the calculation Pseudomonas aeruginosa and Staphylococcus aureus received maximal score (20 points). Therefore, these two types of bacteria are indicative microorganisms. The detection of these microorganisms in split systems will indicate to the contamination of air-conditioning system. This microflora also is a criterion of cleaning and disinfection quality - presence of these microorganisms in the samples after this process will mean that the processing of air conditioning systems was performed poorly. Conclusions. Split systems are very faster colonized by conditionally pathogenic and pathogenic microflora. To prevent the possible hazard for population’s health it is necessary to develop the normative base, according to which sanitary-and-hygienic control over the split-systems working must be carried out. Proposed criteria suggest that Pseudomonas aeruginosa and Staphylococcus aureus are indicative microorganisms, and it’s identification in the air-conditioning system would mean risk for health and necessity for cleaning and disinfection.

Geomantic theory is a natural science integrating geophysics, hydrogeology, astrology, meteorology, environmental landscape science, architecture, ecology, and human life information science. Its purpose is to carefully examine and understand the natural environment, to use and transform the nature, to create a good living environment, to win the best time, place, and people, to achieve the perfect realm of the unity of nature and man. In today’s rapid economic development and social progress, how to effectively combine architectural geomantic omen with contemporary architectural design is the concrete embodiment of modern geomantic omen culture keeping pace with The Times, and is also an important subject faced by Chinese traditional culture to benefit contemporary people and promote economic development. This paper combines Chinese geomantic omen with modern architecture and discusses the site selection of modern architecture under the guidance of geomantic omen based on the current ecological environment construction. This paper studies the site selection of ecological buildings under the guidance of geomantic omen, which provides a new idea for the application of ancient geomantic omen in the future site selection of buildings. To treat Chinese geomantic culture correctly, Chinese architecture, as the carrier of Chinese culture, should inherit critically, explore its scientific essence, and use the past for the present or use it with a little modification. This paper attempts to learn from the traditional Chinese geomantic concepts, such as wind, air, sunshine, water, and so on, and apply them to the current ecological building site selection. According to the natural environment analysis, starting from the current actual environment, applying ancient geomantic in modern construction site, adjust measures to local conditions, such as mountain gives a new meaning, while retaining the maximum illumination area, environment, plant more traditional geomantic meaning, create more appropriate, good living environment, also accord with the demand of the national ecological construction. In this paper, the attitude of advancing with The Times to look at geomancy, let geomancy theory towards the direction of the development of the real society, which is the contemporary people to study geomancy, promote geomancy theory, use geomantic omen for the benefit of modern architecture of the main task.

The focus of this work is to simulate and optimize thermal comfort in a ship air-conditioning system by evaluating the performance of different types of air supply outlets. Thermal comfort analyses were performed in Solidworks Flow Simulation software by changing the number, type and position of air supply outlets and the comfort was optimized by evaluating the values of temperature, velocity, PMV (Predicted mean vote) & PPD (Predicted Percentage Dissatisfied). It was concluded from the results obtained from different analyses that air supply outlet is a vital part in any type of HVAC (Heating ventilation & air conditioning) system design, as its number, type and position has significant effect on the air distribution and thermal comfort in a subject space. It was also deduced that improper selection of air supply outlet can result in room air stagnation, unacceptable temperature gradients, and undesirable velocities in the occupied zone that may lead to occupant discomfort. Through this work the importance and effectiveness of CFD (computational fluid dynamics) design tools, in the design & optimization of HVAC systems has been evaluated and it was concluded that CFD design software like Solidworks flow simulation provide an excellent provision to validate different aspects of HVAC design before actual construction.

Design methodology for reinforced concrete of nuclear power plants to reduce radioactive wastes in decommission phase has been developed. To realize this purpose, (1) development of raw materials database of cements, aggregates and steel bars on concentration of radioactive target elements, (2) trial production of low activation cements and steel bars based on the material database developed in (1), and (3) development of tools for estimation and prediction of the amount of radioactive elements in reactor shielding walls have been carried out. Radioactive analysis showed that Co and Eu were the major target elements which decide the radioactivity level of reinforced concrete from wide survey of raw materials for concrete (typically aggregates and cements). Material database for the contents of Co and Eu was developed based on the chemical analysis and radioactivation analysis. Upon the above survey and execution expreiment of concrete, six types of low-activation concrete are proposed for various radioactive portion in the plant. These concrete have a 1/10 – 1/300 rasioactivity compare to the ordinary concrete, which are assumed the concrete with Andesite aggregate and ordinary Portland cement. Baed on the above data base, it was clarified that the low activation cement would be successfully manufactured by adequate selection of raw materials. The prospect to produce the low-heat portland cement which would have a 1/3 radioactivity in comparison with conventioanl cements obtained by means of selection of limestone and natural gypsum. An attempte was carried out to produece low activation heavy-mortar which would have radioactivity below the clearance level when using at the radiation shielding wall of BWR. Characterization and optimization of consturction conditions with new additives have also been carried out. These two new raw materials for low-activation concrete are conducted in pre-manufacture size, and over the laboratry level. Boron added low-activation concrete are also carried out as extreamly high performance low-activation concrete. It was claryfied that the accurcy of calculation results of the radioactivity evaluation was very high compared to available benchmark calculation for the JPDR and commercial light water reactor. The specification of the mapping system for judging the activation classification was also developed by using the general-purpose radio activation calculation tool. This work is supported by a grant-in-aid of Innovative and Viable Nuclear Technology (IVNET) development project of Ministry of Economy, Trade and Industry, Japan.
