Applications of Calorimetry in a Wide Context - Differential Scanning Calorimetry, Isothermal Titration Calorimetry and Microcalorimetry
Calorimetry, as a technique for thermal analysis, has a wide range of applications which are not only limited to studying the thermal characterisation (e.g. melting temperature, denaturation temperature and enthalpy change) of small and large drug molecules, but are also extended to characterisation of fuel, metals and oils. Differential Scanning Calorimetry is used to study the thermal behaviours of drug molecules and excipients by measuring the differential heat flow needed to maintain the temperature difference between the sample and reference cells equal to zero upon heating at a controlled programmed rate....

ENERGY STORAGE – TECHNOLOGIES AND APPLICATIONS
Overall structure of electrical power system is in the process of changing. For incremental growth, it is moving away from fossil fuels - major source of energy in the world today - to renewable energy resources that are more environmentally friendly and sustainable [1]. Factors forcing these considerations are (a) the increasing demand for electric power by both developed and developing countries, (b) many developing countries lacking the resources to build power plants and distribution networks, (c) some industrialized countries facing insufficient power generation and (d) greenhouse gas emission and climate change concerns. Renewable energy sources such as wind turbines, photovoltaic solar systems, solar-thermo power, biomass power plants,...

Promoting International Energy Security
The dramatic rise in oil prices in 2008 increased attention on the sources of imported oil, the workings of the world oil market, and the potential problems of meeting future demand for liquid fuels. Energy security concerns typically focus on the Middle East, mainly because that is where surplus oil production capacity is concentrated. But a large amount of the world’s oil and natural gas production occurs in countries outside o

The Coming of the Ice
at dinner. So I immersed myself in one of the surgeon's volumes from his fine Library of Imagination, and waited. I think the book was one of Mr. H. G. Wells', probably The Sleeper Awakes, or some other of his brilliant fantasies and predictions, for I was in a mood conducive to belief in almost anything when, later, we sat down together across the table. I only wish I could give some idea of the atmosphere that permeated our apartments, the reality it lent to whatever was vast and amazing and strange. You could then, whoever you are, understand a...

The Cuckoo Clock
Death wore the seeming of a battered Chevrolet. The child's scream and the screech of rubber on concrete knifed through two seconds of time before snapping, like a celery stalk of sound, into aching silence. The silence of limbo, called into being for the space of a slow heartbeat. Then the thud of running feet, the rising hubbub of many voices. Give her air! Keep back. Don't try to move her. Somebody call an ambulance. Yeah, and somebody call a cop, too. I couldn't help it. It was the driver of the ramshackle Chevvie. She fell off the curb right...

Plant Engineers and Managers Guide to Energy Conservation
In the year 2000 energy again made the headlines. Energy management programs that became dormant were revitalized. Companies again became aware that the energy problems of the 1970s, 1980s and 1990s did not go away. The California “power crisis” indeed could spread to other states and not only impact a company’s profitability but could also put many out of business. The first edition of Plant Engineers and Managers Guide was written in 1977 and it was the first book to address the need for industrial energy management....

Poisoned Air
A telephone bell jangled insistently. The orderly on duty dropped his feet from the desk to the floor and lifted the receiver with a muttered curse. Post hospital, Aberdeen Proving Ground, he said sleepily, rubbing his eyes. A burst of raucous coughing answered him. Several times it ceased for an instant and a voice tried to speak, but each time a fresh spasm of deep-chested wracking coughing interrupted. Who is this? demanded the now aroused orderly. What's the matter? Between intervals of coughing difficultly enunciated words reached him. This is—uch! uch!—Lieutenant Burroughs at the—uch!—Michaelville range. We have been—uch!—caught in a...

Of Time and Texas
IN ONE fell swoop, declared Professor C. Cydwick Ohms, releasing a thin blue ribbon of pipe-smoke and rocking back on his heels, —I intend to solve the greatest problem facing mankind today. Colonizing the Polar Wastes was a messy and fruitless business. And the Enforced Birth Control Program couldn't be enforced. Overpopulation still remains the thorn in our side. Gentlemen— He paused to look each of the assembled reporters in the eye. —there is but one answer. Mass annihilation? quavered a cub reporter. Posh, boy! Certainly not! The professor bristled. The answer is—TIME! Time? Exactly, nodded Ohms. With a dramatic...

The Outbreak of Peace
It was a great pity, Space Marshal Wilbur Hennings reflected, as he gazed through the one-way glass of the balcony door, that the local citizens had insisted upon decorating the square before their capitol with the hulk of the first spaceship ever to have landed on Pollux V. A hundred and fifty years probably seemed impressive to them, amid the explosive spread of Terran colonies and federations. Actually, in the marshal's opinion, it was merely long enough to reveal such symbols as more than antiquated but less than historically precious. I presume you plan to have me march past that...

A Journey into the Center of the Earth
The Voyages Extraordinaires of M. Jules Verne deserve to be made widely known in English-speaking countries by means of carefully prepared translations. Witty and ingenious adaptations of the researches and discoveries of modern science to the popular taste, which demands that these should be presented to ordinary readers in the lighter form of cleverly mingled truth and fiction, these books will assuredly be read with profit and delight, especially by English youth. Certainly no writer before M. Jules Verne has been so happy in weaving together in judicious combination severe scientific truth with a charming exercise of playful imagination. Iceland,...

The Clean and Wholesome Land
WHILE Professor Cargill lectured from the rostrum, Neal Pardeau prowled the dark auditorium. This, he knew, was the place to find them. Here was where they whispered and plotted and schemed—feeling safe in this pure, hard core of patriotism. Safe because Cargill was the Director of Education in the New State, just as Pardeau was the Director of Public Security. Safe because Cargill's lectures were given before a commanded audience, with attendance strictly mandatory. The insistence was not really necessary of course. The people would have come to hear Cargill regardless. His was a compelling, magnetic personality. Even now his...

Distributed Arrays of Small Instruments for Solar-Terrestrial Research Report of a Workshop
The Sun is the primary source of energy at Earth, and the Sun’s output determines the conditions in interplanetary space at Earth and throughout the solar system. Earth’s magnetic field and associated electrical current systems are continuously reacting to changing conditions in the solar wind that are driven by processes occurring at the Sun. The characteristics of Earth’s ionosphere and neutral thermosphere are influenced both by local processes and by coupling of the ionosphere and thermosphere to the overlying regions of the geospace1 environment....

Energy Research at DOE WAS IT WORTH IT? Energy Efficiency and Fossil Energy Research 1978 to 2000
From the time of the first Organization of Arab Petroleum Exporting Countries oil embargo nearly 30 years ago, the United States has looked to new technology for solutions to its energy problems. Indeed, the first government reports to recommend an energy research and development (R&D) agenda appeared within weeks of that 1973 event. In 1975, President Ford created the Energy Research and Development Administration (ERDA), consolidating under one umbrella existing R&D energy programs from several agencies. In late 1977, ERDA became part of the new Department of Energy (DOE). And today, energy R&D remains a major element of DOE’s mission....

Coal: Research and Development to Support National Energy Policy
The extraordinarily broad scope of the congressional request for advice on coal resources and future coal research and development needs provided a significant challenge for the committee appointed by the National Research Council (NRC). Fortunately, clarifications by staff members from the offices of U.S. Senators Robert C. Byrd and Arlen Specter—the originators of this study—were most helpful, suggesting that the report should be brief and contain limited detail, but with abundant references to other, more comprehensive studies. They also emphasized that a major element of their request was to learn of any potential roadblocks that might impinge on the production or delivery of coal should the nation’s energy requirements...
