Physical law not natural selection as the major determinant of biological complexity in the subcellular realm: new support for the pre-Darwinian conception of evolution by natural law

Before Darwin many biologists considered organic forms to be immutable natural forms or types which like inorganic forms such as atoms or crystals are part of a changeless world order and determined by physical law. Adaptations were viewed as secondary modifications of these ‘crystal like’ abstract afunctional ‘givens of physics.’ We argue here that much of the emerging picture of biological order in the subcellular realm resembles closely the pre-Darwinian conception of nature. We point out that in the subcellular realm, between nano and micrometers, physical law necessarily plays a far more significant role in organizing matter than in the familiar ‘Darwinian world’ between millimeters and meters (where matter can be arranged into almost any contingent artifactual arrangement we choose, as witness Lego toys, watches or jumbo jets). Consequently, when deploying matter into complex structures in the subcellular realm the cell must necessarily make extensive use of natural forms—such as the protein and RNA folds, microtubular forms and tensegrity structures—which like atoms or crystals self-organize under the direction of physical law into what are essentially ‘pre-Darwinian’ afunctional abstract molecular architectures in which adaptations are trivial secondary modifications of what are evidently primary givens of physics.

How business scorecards help to fly the corporate flag

For Jumbo Jet pilots certain information is crucial. They would not take off in a plane whose fuel gauge goes on only when the tank is empty even if they were supplied with plenty of other flight information such as the position of first‐class seats. The key to success for every pilot is to run the plane with a few but essential indicators and the same principle applies to companies. Organizations need to differentiate what is important from what is superfluous. The balanced scorecards system (BSC) is a model that helps us to do just that.

India´s Relations with Southeast Asia Take a Wing

Chok Tong portrayed India as one wing of ASEAN's jumbo jet, with the People's Republic of China (PRC) and Japan as the other wing.1 Leaving aside whether such a plane could take off, much less land, safely, the comment describes, certainly inadvertently, India's idiosyncratic ties with Southeast Asia both bilaterally and relative to the region's other formal partners. These attributes include: fresh and ancient links; importance and marginality; episodic engagement and occasional estrangement with long spells of detachment; and mutual insensitivity and over-sensitivity. The erratic connections between India and Southeast Asia mean that a linear review of political, economic, and security ties will yield only a partial picture of current and possible future India-Southeast Asia relations. The approach employed here, therefore, is to briefly review the features of India-Southeast Asia relations, and then examine the manner and extent to which India's domestic politics and economics, its South Asian neighbourhood relations, and its foreign policy generally impinge upon its ties with Southeast Asia. For it is precisely these factors that have both facilitated and constrained India's rapprochement with Southeast Asia beginning in the early 1990s, and are likely to shape relations in the coming decade. The chapter concludes with a brief assessment of India-Southeast Asia relations.

Unconventional nuclear weapons

Of the countless scenarios of terrorist mayhem, none quickens the pulse quite like the menace of a nuclear bomb. In light of the low-tech but catastrophic attacks on the World Trade Centre, building a nuclear bomb suddenly seems an unnecessarily difficult and risky proposition. Why build a bomb when there are far cheaper and simpler ways of waging nuclear terror? Analysts have accordingly turned their attention to two other possibilities that, for all their comparative simplicity, would deliver much of the bang of a bomb. Flying a fully fueled jumbo jet into a nuclear reactor is one. The other is using radioactive nuclear materials to kill or sicken people or render tracts of land uninhabitable by, for example, scattering the materials with a conventional explosion. This paper briefly discusses the likelihood of these two types of terrorist attack and the need to protect nuclear power stations and spent fuel from theft by terrorists.

Tenerife Revisited: The Critical Role of Dentistry

The authors record the contribution of dentistry to the identification of victims of one of the most significant disasters in the history of aviation-the March 1977 collision of two Boeing 747 jumbo jets in the Canary Islands, which resulted in 583 fatalities. Dental identification was the primary method of victim identification because a high percentage of the bodies were severely burned. Virtually all aspects of the U.S. identification efforts have been reported with the exception of the valuable role of dentistry. The dental team's organization, methodology, and significant contributions to forensic dentistry and a variety of remarkable problems that the team encountered are documented.

A General Theory of Russian Space: A Gay Science and a Rigorous Science

Living in a brave new world of jumbo jets, computer networks, and fast-food chains, we are tempted to believe that geography can be overruled by technology, that space can be conquered by means of communication. However, there is an exception lying flat and square across Eurasia and occupying about one-seventh of world map. This is Russia, where space reigns supreme, defying modern communications, technologies, and beliefs, and defining political institutions, economic activity, and mentality of its population. Space is generally considered to be a major Russian asset, but isn't it also a major pain in neck? True, it shapes a mysterious Russian soul, with its breadth and depth, its abysses, and the ideal of Madonna living side by side with ideal of Sodom like ebony and ivory on a piano keyboard, as testified by Dostoyevsky. True, Russia's coat of arms is a double-headed eagle, borrowed from Byzantium (not mutating after Chernobyl), with one head looking east, other west. And yet again, it is true that Russia, with its vastness, cannot be embraced by mind,1 as observed by Tyutchev and repeated by many for more than a century as an ultimate justification for everything that happens in that country. It is this same space that has prevented Russia from developing civil institutions, civic society, and rule of law (Rechtsstaat) in fact entire concept of civility, from civitas, is a specifically Western way of development by urbanization. In Russia, there has been little necessity to settle down and work at a plot of land. Endless space is forgiving and undemanding, irresponsible and undiscriminating; its human embodiment is weak-willed and dreamy Iliya Iliych Oblomov of Ivan Goncharov's classical novel, a Russian archetype.

Detecting Illegal Substances

Unlocking The Secrets Of Supersniffing Dogs In Sydney, Australia, Jamie begins a busy day with grooming, exercise, and a health check. He then travels to the airport for the day's first task, inspecting cargo from a number of jumbo jets parked on the tarmac. From the airport, he moves to the location where mail is imported to check half a million or so articles. Next, he goes to the waterfront to search a ship—and the day isn't over yet. Jamie, an athletic, black Labrador retriever trained by the Australian Customs Service to search for narcotics, epitomizes the unrivaled ability of dogs to locate objects through their sense of smell. Yet, it is not fully understood how dogs do what they do and why they are so good at it. Basic studies of canine olfaction and breeding are helping researchers figure out the secrets of the dog's exquisite detection capabilities. They are also generating knowledge ...

A Personal Journey Through South Africa with the Curriculum Development Committee of People to People International

People To People Delegation arrived after a fourteen hour flight. As we left the 747 South African Airlines (SAA), an unusual cool breeze greeted us as we unhanded the jumbo jet. We headed for official screening and passport identification, then on to claiming our luggage and through customs. The money exchange rate was R 4.45 to the dollar. After a brief roll call, we boarded the bus for The Balalaika Hotel & Crown Court, where we would spend the next three days. The first corporate logo I noticed driving into town was Xerox, then Siemens, Chrysler, Toyota and many more. The driver's steering column is on the right in South Africa and many Mercedes Benz, BMW, Volkswagen, and Japanese imports stood gleaming in the rush hour traffic. This environment is not much different from

Chapter 5 Corporate Concomitant Coalitions (CONCOLs) to Reap Broadband Network Technology (BNT) Bounty

US Vice President Albert Gore first used on March 21,1994, what later became the phrase: “Information Superhighway,” The phrase suggests that information traffic rolls right over the static, long‐suffering fixture of mud, concrete and asphalt. But with each new development of IT, it is as though the vehicles have to renegotiate with the roadway the right of passage, making it very much an interactive process. To underscore its dynamic nature, a transportation analogy seems appropriate. If we are today in the propeller airplane stage, Broadband Network Technology (BNT) is beyond Supersonic Concorde, to reach which we need to traverse through [1] turbo‐prop technology, [2] jet engine technology, [3] 747‐technology, [4]jumbo jet technology, and [5] supersonic technology to [6] supersonic+ technology. Information Superskyway should result in what Dertouzos, Director of MIT Computer Science Labatory, calls Information Marketplace: “the collection of people, computers, communications, software and services that will be engaged in the intraorganizational and interpersonal informational transactions of the future.” 3C firms jockey for position on the Information Superskyway. While they offer better access to the Internet, they also seek to restrict the access to products and services they control. Dertouzos says that all companies shoud cooperate with their competitors to build a shared information infrastructure, so that they can compete. It echoes our own definition of Concomitant Coalition: association of one party(ies) with and against the same party(ies) in the same game or activity. We discuss three CONCOLs: [1] Microsoft‐Netscape working together and in competition, as Bill Gates puts it, to define standards that will help overcome the Internet's limitations. They compete on supplying components of the software platform for interactive networks; but they cooperate in developing an industry standard, no matter whose components finally get accepted. [2] Sun‐NCR‐Intel working together against Microsoft which is pushing its Windows NT as a substitute for Sun's Unix operating system. [3] Intel‐SAP working together against Microsoft, IBM on business management software. Pandesic, the 50–50 joint venture between Intel (whose chips control the basic functions of 80 percent of the world's PCs), and Germany‐based SAP (the world's biggest publisher of business management software), will provide on‐line merchants the necessary hard‐and‐software, to tap into the projected US$234 billion economy on the Internet by the year 2002. We saw in Chapter 4 that the main players in 3C industries are racing each other on their own pathways to the Information Superskyway. In this chapter we find 3C firms entering into CONCOLs to tap into the rich bounty on the Internet. However, Dertouzos warns that none of the awesome powers of fiber optics, real‐time video, virtual reality, multimedia, and electronic commerce would be realized unless computers and software at diverse sites can “understand” one another. But he says: “Hardly anyone today is paying attention to shared conventions that will allow interconnected machines to understand and work with each other without the constant intervention of a human being.”

Chemical analysis used to aid crash probe

Chemical analysis is one of the essential tools that will be used to identify the cause of the midair explosion and crash of Trans World Airlines Flight 800 into the ocean off New York's Long Island. By press time last week, the flight data recorders had been recovered, but no conclusions had been reached about what made the jumbo jet explode and fall from the sky on July 17, killing 230 passengers and crew members. Investigators are considering three possible causes of the accident: a technical malfunction in the aircraft, a bomb, or a missile. National Transportation Safety Board (NTSB) personnel are working in conjunction with the Federal Bureau of Investigation to recover and study aircraft parts and contents. The Bureau of Alcohol, Tobacco & Firearms is also assisting in the inquiry, an explosives expert at the agency tells C&EN. Specialists in forensics and explosives— speaking conceptually about an investigation such as the TWA Flight ...

Aerospace and military

The paper describes how "smaller, faster, cheaper" were the watchwords in 1995 as aerospace and military program managers tried to cut the cost of doing business-without cutting the missions or goals of their programs. One of the most ambitious of these efforts took place at the US National Aeronautics and Space Administration, Washington, DC, which moved to slash its workforce and to develop new lines of spacecraft that would be smaller and more autonomous than the Galileo vehicle, which limped to Jupiter with the assistance of a legion of ground controllers. Civilian aircraft companies expected to sell more commuter aircraft than jumbo jets. And the military found that defending itself against battlefield missiles is still as difficult as it was in Desert Storm.

The Diary of a Breast

Elisa Seagrave Faber, pounds sterling9.99, pp 287, ISBN 0 571 17446 9 Talk of an epidemic of breast cancer may seem alarmist, but in the United Kingdom alone the current death rate equals the loss of a fully occupied jumbo jet every week. Cathy Read's book, with its Stateside perspective and highly combative style, maintains that breast cancer is avoidable, but that the focus has shifted from prevention to early detection and treatment. Read is very suspicious of the medical profession and its vested interests and poses some uncomfortable questions about this multibillion dollar industry. Why, she wonders, has there been no notable increase in survival rates despite the widespread screening of premenopausal women …

Demand For Carbon Fibers Rebounds Despite Continued Aerospace Slump

Carbon fibers have long been the stuff that dreams are made of. Without carbon fibers, the whiz-bang technology of the late 20th century would not have been possible. Radar-transparent military aircraft, light and durable communications satellites, jumbo jets, and high-temperature-tolerant rocket motor nozzles all owe the very fiber of their being to the strength and rigidity of carbon fibers. Carbon fibers are a minuscule business when compared with the more than 40 billion lb per year that producers of synthetic fibers such as nylon and polyester sell worldwide for textile and industrial uses. But carbon fibers, with about 15 million lb per year of business globally, are worlds apart in price and performance from their ordinary cousins. Whereas synthetic fibers sell for anywhere from 80 cents to a few dollars per pound, carbon fiber prices can range from about $10 to more than $100 per lb for specialty aerospace grades. Production of carbon fibers—whether based ...

One short leap for man..

I was reminded of an ethically suspect animal experiment by this riveting programme covering the United Nation's Cairo Conference on Population Development: if a frog is dropped into boiling water in a frying pan it will leap out unharmed, but if placed in cold water that is gradually heated to the same final temperature the frog will die where it is. Humanity also reacts more effectively to dangers that are sudden than to equivalent dangers produced gradually by adverse trends. The increase in human numbers is three every second - or a jumbo jet arriving every two minutes. Although this growth adds to increasing consumption and pollution and leads to progressive destruction of habitats for all other species; although it swamps development efforts and exacerbates, as in Rwanda, the tensions that lead to human conflict: to most …

風防ガラス・クリーニング・ロボットの開発

This paper describes the development of Windshield Cleaning Robot System : WSC. This system is intended to be used for Boeing 747, commonly called jumbo jet, parked at airports prior to service. The objects to be cleaned are spots on windshields caused by collision with dusts, insects, and birds during takeoff and landing. The intention of this new system is that one operator would perform the whole work in 10 minutes. So the system consists of the manipulator (the arm and the cleaning device), the installation unit, the control unit, and the operation unit. A position and force control method is applied to this system. The target position of the arm tip is modified using the signals from the force sensor and the joystick. In accordance with this control method, the pressure force is kept constant and the tip is moved so as to follow the shape of the windshields. The various safety features provided include interference limit to limit the area of movement. System experiments were carried out and the effectivity applying lightweight manipulator with long arms to this work was confirmed.
