Access to information using the Internet has undergone dramatic change and expansion recently. The unrivaled success of the World Wide Web has altered the Internet from something approachable only by the initiated to something of a media craze — the information superhighway made manifest in the personal "home page". This paper surveys the beginnings of network information discovery and retrieval, how the Web has created a surprising level of integration of these systems, and where the current state of the art lies in creating globally accessible information spaces and supporting access to those information spaces.

The Information SuperHighway, Email, The Internet, FTP, BBS, Modems, : all buzz words which are becoming more and more routine in our daily life. Confusing terminology? Hopefully it won't be in a few minutes, all you need is to have a handle on a few basic concepts and terms and you will be on-line with the rest of the "telecommunication experts". These terms all refer to some type or aspect of tools associated with a range of computer-based communication software and hardware. They are in fact far less complex than the instruments we use on a day to day basis as microscopist's and microanalyst's. The key is for each of us to know what each is and how to make use of the wealth of information which they can make available to us for the asking. Basically all of these items relate to mechanisms and protocols by which we as scientists can easily exchange information rapidly and efficiently to colleagues in the office down the hall, or half-way around the world using computers and various communications media. The purpose of this tutorial/paper is to outline and demonstrate the basic ideas of some of the major information systems available to all of us today. For the sake of simplicity we will break this presentation down into two distinct (but as we shall see later connected) areas: telecommunications over conventional phone lines, and telecommunications by computer networks. Live tutorial/demonstrations of both procedures will be presented in the Computer Workshop/Software Exchange during the course of the meeting.

Sir Charles Parsons died some three years after the author was born. In this paper the author looks back at the pioneering work of Parsons in the field of power generation. It shows how he was able to increase output of the steam turbine generator from 7.5 kW in 1884 to 50000 kW in 1930 while increasing efficiency from 1.6 to 36 per cent, and relates these achievements to the current state of the art. Blading design, rotor construction and other aspects of turbine engineering are considered. The conclusion is that Parsons and his associates charted the course which manufacturers and utilities throughout the world have continued to follow, although increasingly sophisticated design and analytical methods have succeeded the intuitive approach of Parsons. His constant search for improved efficiency was and is highly relevant to today's concern for the environment. Finally, although it did not become a practical proposition in his lifetime, the paper reviews Parsons' vision of, and continuing interest in, the gas turbine, first mentioned in his 1884 patents.

The Internet, a military creation, is a collection of services shaped by its users, and offers the rapid transfer of vast quantities of information. Already there is concern that Developing World countries may be left behind by this revolution in information availability. Psychiatrists need to be aware of the type of facility the information in the superhighway provides, so that the useful aspects can be refined and directed. The type of facilities in use now by psychiatrists around the world is briefly described.

Today the world has turned its attention to the phenomena of climate change on the planet. Excess emissions of greenhouse gases (GHG) from human activity are responsible for this change. Gases such as carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) are part of GHG and have a large capacity to store the energy of the sun in the form of heat, increasing the average temperature in the atmosphere. After the Kyoto treaty, major powers pledged to reduce GHG emissions into the atmosphere, but this practice implies a slowdown in the industrialization and profits of these countries. Countries that can not or do not opt to reduce emissions can buy credits from nations that can generate extra emission reduction values, thus resulting in trade in these credits. Small properties have the potential for credit production, which can generate extra income for the small producer. Therefore, this work aimed at evaluating the potential of commercialization of carbon credits by small properties. The methodology of the work consisted in a systematic literature review on the current state of the art of the proposed theme.

Peritoneal carcinomatosis (PC) is a global challenge of modern oncology representing the most unfavourable scenario in diverse-locality tumourisation. Despite certain attention by the oncological community, the management of PC patients is currently palliative, which weakly promotes research into the basic principles of this morbidity. This literature review attempts to comprehensively cover the PC problematic from a global perspective and presents a key evidence on the world schools of thought in this area. Briefly taking, peritoneal carcinomatosis is viewed today as a local process in the conventional implantation theory, which imposes a locoregional character on all current or emerging therapies, such as cytoreductive surgery and hyperthermic intraperitoneal chemotherapy. Their inadequate efficacy is largely due to pronounced gaps in our understanding of PC logistics and signalling. PSOGI is a key organisation for centralising the specialty effort in peritoneal carcinomatosis. Despite its global geography and approach to PC discussion, a multitude of scientific questions remain unanswered impeding the establishment of novel effective therapies. The seven countries that nurtured distinguished schools of thought in PC studies are the USA, UK, Japan, China, Italy, France and Germany. Taking peritoneal carcinomatosis in a global perspective, an insufficient attention to its problematic in Russia should be addressed. The founding and fostering of national PC institutions will benefit cancer patients and progress in oncological science.

A recent report from China Internet Network Information Center indicates that by the end of June 2015, 668 million Chinese have used the internet, which places China as the country with the most internet users in the world. As more Chinese get online, the internet has been integrated into providing education in China, where the age group using the internet the most often is between the ages of 20 and 29. Many of these youth are higher education students. With 34.6 million students the Chinese higher education system is the largest in the world, in which a significant proportion of the students' learning has been impacted by information and communication technology (ICT). The purpose of this article is to provide an overview of how the development of ICT in China has influenced higher education, what opportunities ICT offers for higher education, and what challenges Chinese face in further developing higher education with ICT.

The world of commerce has undergone a transformation since the early 1990s, which has increasingly included the utilization of information technologies by firms across industry sectors in order to achieve greater productivity and profitability. In other words, through use of such technologies as mainframes, PCs, telecommunications, state-of-the-art software applications and the Internet, corporations seek to utilize productive resources in a way that augment the efficiency with which they provide the most appropriate mix of goods and services to their ultimate consumer. This process has provided the backbone to the evolution of the information economy which has included increased investment in information technology (IT), the demand for IT labor and the initiation of such new paradigms as e-commerce.

The World Wide Web is known as the “universe of network-accessible information, the embodiment of human knowledge” (W3C, 1999). Internet-based knowledge management aims to use the Internet as the world wide environment for knowledge publishing, searching, sharing, reusing, and integration, and to support collaboration and decision making. However, knowledge on the Internet is buried in documents. Most of the documents are written in languages for human readers. The knowledge contained therein cannot be easily accessed by computer programs such as knowledge management systems. In order to make the Internet “machine readable,” information extraction from Web pages becomes a crucial research problem.

Dupuytren’s disease is a fibroproliferative disease that involves collagen deposition, leading to hand contractures that ultimately affect hand mobility and grip strength. It is a benign disorder but can cause high morbidity by limiting daily activities. Many factors have been proposed for its aetiology: namely genetics, smoking, alcohol intake and diabetes. However, there is still controversy as to the main aetiological cause of the disease. Treatment is not yet uniform around the world and still varies with the surgeon’s experience and preference. In this review, the authors review the pathogenesis and treatment options for Dupuytren’s disease in an attempt to summarize the current state of the art.
