Nanotechnology will serve as a suitable solution to achieve high performance in future construction. Using this new technology results in creativity and innovation in the construction industry. One of these new technologies is the smart concrete which has received much emphasis in recent years. Many research and experiments have been conducted in scientific research centers around the world in this regard. It is an undeniable fact that concrete structures are prone to cracking. Natural processes have caused cracks in the concrete through which harmful substances entered the concrete leading to steel corrosion. To tackle this issue through the conventional method of concrete restorative, materials, especially polymers which are also harmful to the environment, are used. An alternative that the scientists have achieved is to employ bacteria in concrete through which to produce self-healing concrete and also to reduce the problems regarding the maintenance of concrete for the environment. Bacteria contribute to the durability and performance of the concrete and increase the service life of the concrete.

Performance Computing

Recent events in the high-performance computing industry have concerned scientists and the general public regarding a crisis or a lack of leadership in the field. That concern is understandable considering the industry's history from 1993 to 1996. Cray Research, the historic leader in supercomputing technology, was unable to survive financially as an independent company and was acquired by Silicon Graphics. Two ambitious new companies that introduced new technologies in the late 1980s and early 1990s—Thinking Machines and Kendall Square Research—were commercial failures and went out of business. And Intel, which introduced its Paragon supercomputer in 1994, discontinued production only two years later.During the same time frame, scientists who had finished the laborious task of writing scientific codes to run on vector parallel supercomputers learned that those codes would have to be rewritten if they were to run on the next-generation, highly parallel architecture. Scientists who are not yet involved in high-performance computing are understandably hesitant about committing their time and energy to such an apparently unstable enterprise.However, beneath the commercial chaos of the last several years, a technological revolution has been occurring. The good news is that the revolution is over, leading to five to ten years of predictable stability, steady improvements in system performance, and increased productivity for scientific applications. It is time for scientists who were sitting on the fence to jump in and reap the benefits of the new technology.

And Performance

It is a well-known fact that the 1989 Exxon Valdez disaster caused the escort towing of laden tankers in many coastal areas of the world to become compulsory. In order to implement a new type of escort towing, specially designed to be employed in very adverse weather conditions, considerable changes in the hull form of escort tugs had to be made to improve their stability and performance. Since traditional winch and ropes technologies were only effective in calm waters, tugs had to be fitted with new devices. These improvements allowed the remodeled tugs to counterbalance the strong forces generated by the maneuvers in open waters. The aim of this paper is to perform a comprehensive literature review of the new high-performance automatic dynamic winches. Furthermore, a thorough analysis of the best available technologies regarding towline, essential to properly exploit the new winches, will be carried out. Through this review, the way in which the escort towing industry has faced this technological challenge is shown.

The Cost

The rural wireless networks are increasingly in demand by associations and autarchies to expand Internet access in this type of areas. The problem of such solutions centers not only in network deployment and its maintenance, but also in the equipment installation on clients, which always has big costs. This installation and configuration must be performed by a technician on site, so that the equipment can be integrated in the infrastructure. To try to mitigate this problem, it is presented a solution that allows the clients to install, with transparency, the device at home, reducing not only the cost for the management entity but also for the clients. This way, for info-excluded people or with new technology low experience level, it is the user that integrates himself in the network, making him part of the process, fostering the network usage.In this article are specified not only the system architecture but also the way that it works and how it obtains the desirable result. The tests made to the solution show the quickness, reliability and autonomy in the execution of the tasks, making it a benefit for rural wireless networks.This solution, by its robustness and simplicity, allowed an uptake to the IT by people who never thought to do it, namely an advanced age group (elderly) who want to join the world of the new technologies

Electronic networking has been welcomed in Australia not least because of its potential to help solve problems of distances within Australia and of the isolation of Australia. In the world as a whole, the Internet, and the World Wide Web in particular, is transforming the communication of art information and access to art images. Three Australian Web servers focus on the visual arts: Art Serve, Diva, and AusArts. A number of initiatives intended to provide online bibliographic databases devoted to Australian art were launched in the 1980s. More recently a number of CD-ROMs have been published. As elsewhere, art librarians in Australia need new skills to integrate these products of new technology into the art library, and to transform the latter into a multimedia resource centre.

The Relationship

With the advent of new technologies, the man begins to experience a significant change in the perception of the other, time and space. The acceleration of time promoted by new technology does not allow the exercise of affection for the consolidation of ties, relations take narcissists hues seeking immediate gratification and the other is understood as a continuation of the self, the pursuit of pleasure. It is the acceleration of time, again, which leads man to present the need for immediate, always looking for the new – not new – in an attempt to fill an inner space that is emptied. The retention of concepts and pre-stressing of temporality are liquefied, become fleeting. We learn to live in the world and the relationship with the other in a frivolous and superficial way. The psychic structure, facing new phenomena experienced, loses temporalize capacity and expand its spatiality, it becomes pathological. Post-modern inability to retain the past, to analyze the information received and reflect, is one of the responsible for the mental illness of today's society. From a temporality range of proper functioning, the relationship processes with you and your peers will have the necessary support to become viable and healthy.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Construction industry is one of the devoting force of any country's economy. Around the world, Small Scale Contractors (SSC) has been found to play a significant role in creating jobs, infiltrating new markets and growing the economy in an inspired and inventive way. However, performance of SSCs in developing and minor developed countries is still not in adequate level due to various factors. Poor QS practices is one of the significant factor which affect to the current performance of the SSCs. Hence, this research aims to implement better QS practices to mitigate adverse impact to the small scale contractors due to plenty of poor QS practices. Particularly qualitative research approach was used for this study and accordingly data was collected from semi- structured interviews and analyzed using manual content analysis. Project delays, cost overruns of projects, cash flow problems, unable to win tenders, poor construction quality, delays in payments and contractual disputes were identified as major issues caused by the poor QS practices. This research suggests government to impose laws and regulations, offer tax relieves to contractors and impose legal requirements to participate in CPD sessions to minimize poor QS practices. Further clients and consultants can make timely payments to contractors and key suggestions to contractors are hire experienced and qualified professionals, provide well-coordinated training, adopt new technologies, keep clear and completed drawings and specifications, use cost and time controlling techniques and maintain good record keeping system.
