Honeycomb Pattern

The honeycomb pattern, comes from nature, is one of the inspiration used by architects in their work. The characteristic form of the hexagon, possible to be duplicated as a module in both "pure" and modified form, favours the implementation of more and more spectacular solutions in architecture. The aim of the article is an overview of selected examples of the honeycomb pattern applied in architecture in relation to shaping its basic form (single objects and their complex systems), as well as used in architectonic details at various scales (elements of building facades). The variety of ideas is resulted from the inventiveness of planners and architects, the development of innovative design tools, and the availability of various materials used in construction.

Air Explosion

Blast-resistant buildings are mainly used to protect main instruments, controllers, expensive equipment, and people from explosion waves. Oil and gas industry projects almost always include blast-resistant buildings. For instance, based on a hazard identification (HAZID) and hazard and operability (HAZOP) analysis of a plant, control rooms and substations are sometimes designed to withstand an external free air explosion that generates blast over pressure. In this regard, a building façade is considered to be the first barrier of resistance against explosion waves, and therefore a building façade has an important role in reducing a building’s vulnerability and human casualties. In case of a lack of enough resistance, explosion waves enter a building and bring about irreparable damage to the building. Consequently, it seems important to study and evaluate various materials used in a façade against the consequences of an explosion. This study tried to make a comparison between different types of building facades against explosion waves. The materials used in a building play a key role in the vulnerability of a building. In this research, a literature review and the fuzzy Delphi method were applied to find the most critical criteria, and then a fuzzy evaluation based on the distance from the average solution (EDAS) was applied in order to assess various materials used in building facades from the perspective of resiliency. A questionnaire was presented to measure effective indices in order to receive experts’ ideas. Finally, by implementing this methodology in a case study, it was concluded that a stone façade performs much better against explosions.

The agricultural biogas market differs in different European countries. Both in Europe and in Poland, the basic form is the use of biogas to generate electricity and heat. In nine EU countries, the biogas produced is also used in local gas networks and in transport, especially communal. Biogas production can be based on agricultural raw materials (Germany) or the use and processing of all agricultural, industrial and municipal waste (Denmark, Sweden). The aim of this article is to present dynamics and structure of biogas market development, raw materials used and profitability in various legal and financial models. The presented analyzes have concluded that biogas plants could be an important part of the energy market in the future, particularly at the local level and an important part of a sustainable economy.

Haemostatic disorders are both complex and costly in relation to both their treatment and subsequent management. As leading causes of mortality worldwide, there is an ever-increasing drive to improve the diagnosis and prevention of haemostatic disorders. The field of microfluidic and Lab on a Chip (LOC) technologies is rapidly advancing and the important role of miniaturised diagnostics is becoming more evident in the healthcare system, with particular importance in near patient testing (NPT) and point of care (POC) settings. Microfluidic technologies present innovative solutions to diagnostic and clinical challenges which have the knock-on effect of improving health care and quality of life. In this review, both advanced microfluidic devices (R&D) and commercially available devices for the diagnosis and monitoring of haemostasis-related disorders and antithrombotic therapies, respectively, are discussed. Innovative design specifications, fabrication techniques, and modes of detection in addition to the materials used in developing micro-channels are reviewed in the context of application to the field of haemostasis.

The object of this research is the sun protection devices for translucent enclosing structures such as blinds. The goal of this research lies in examination of the historical experience and modern practice of using sun protection devices. The author conducts retrospective research of the evolution of blinds in order to determine the key stages in the development of structures that regulate the luminous flux. The historical discourse of the evolution of the system of blinds is based on the retrospective analysis of blinds according to the main characteristics, such as materials used, their location (indoors or building facades), and gear options. The author determines three main periods can in the evolution of blinds. The first period started in 1841, when John Hampton patented dentition blinds and lasted until 1936 (the design and materials used did not change throughout this period).The second period lasts from 1936 to 1960, and marks the emergence of the facade constructs "sun-cutter blinds", as well as the use of aluminum for the production of fins. The third period covers 1960s-1970s, is characterized by progressive automatic control, implementation of PVC, and improvement of energy efficiency of blinds using photovoltaic fins.

Children's Museum

Traditional museum is typically characterized especially by presenting exhibits. However, it has recently been enriched by many other features that contribute to the attractiveness of exhibitions. Museum spaces nowadays offer various educational events, creative workshops or shops with artefacts and publications. This paper is aimed at presenting partial research results orientated to human-centered design of museums for children. The introductory part describes innovative design tools that focus on multisensory presentation of exhibits, hands-on, color impact, emotion perception etc., as well as possibilities of using the Universal Design as a Learning method to create exhibitions for children with special needs. The main part of the work consists of our team's research aimed at exploring the needs of different children, especially children with various disabilities, in the creation of children's museum space and exhibitions. The first phase of research is focused on the analysis of spatial properties, exhibits and interactions between them. The aim was to discover how those factors influence children's attention and impact on their learning ability. This part of the research was carried out in BIBIANA - International House of Art for Children in Bratislava. The end of the paper indicates further research possibilities that will be explored in the next phase of our research in the future.

Autonomous, intelligent tools are reshaping all sorts of work practices, including innovative design work. These tools generate outcomes with little or no user intervention and produce designs of unprecedented complexity and originality, ushering profound changes to how organizations will design and innovate in future. In this paper, we formulate conceptual foundations to analyze the impact of autonomous design tools on design work. We proceed in two steps. First, we conceptualize autonomous design tools as ‘rational’ agents which will participate in the design process. We show that such agency can be realized through two separate approaches of information processing: symbolic and connectionist. Second, we adopt control theory to unpack the relationships between the autonomous design tools, human actors involved in the design, and the environment in which the tools operate. The proposed conceptual framework lays a foundation for studying the new kind of material agency of autonomous design tools in organizational contexts. We illustrate the analytical value of the proposed framework by drawing on two examples from the development of Ubisoft’s Ghost Recon Wildlands video game, which relied on such tools. We conclude this essay by constructing a tentative research agenda for the research into autonomous design tools and design work.

Tool materials used in ultramicrotomy are glass, developed by Latta and Hartmann (1) and diamond, introduced by Fernandez-Moran (2). While diamonds produce more good sections per knife edge than glass, they are expensive; require careful mounting and handling; and are time consuming to clean before and after usage, purchase from vendors (3-6 months waiting time), and regrind. Glass offers an easily accessible, inexpensive material ($0.04 per knife) with very high compressive strength (3) that can be employed in microtomy of metals (4) as well as biological materials. When the orthogonal machining process is being studied, glass offers additional advantages. Sections of metal or plastic can be dried down on the rake face, coated with Au-Pd, and examined directly in the SEM with no additional handling (5). Figure 1 shows aluminum chips microtomed with a 75° glass knife at a cutting speed of 1 mm/sec with a depth of cut of 1000 Å lying on the rake face of the knife.

Successful retrieval of the television camera and other components from the Surveyor III spacecraft by the Apollo 12 astronauts has provided a unique opportunity to study the effects of a known and relatively extensive exposure to the lunar environment. Microstructural effects including those produced by micro-meteorite impact, radiation damage (by both the solar wind and cosmic rays) and solar heating might be expected in the materials used to fabricate the spacecraft. Samples received were in the form of 1 cm2 of painted unpainted aluminum alloy sheet from the top of the camera visor (JPL Code 933) and the sides (935,936) and bottom (934) of the lower camera shroud. They were prepared for transmission electron microscopy by first hand-grinding with abrasive paper to a thickness of 0.006". The edges were lacquered and the sample electropolished in 10% perchloric methanol using the “window” method, to a thickness of ~0.001". Final thinning was accomplished by polishing 3 mm punched disks in an acetic-phosphoric-nitric acid solution.
