Abstract
This paper examines how fundamental the principles of thermodynamics are to pharmacy. The paper covers the topics of Gibbs free energy change, heat of formation, partial molar free energy, energy change and entropy, and discusses how all these are important in pharmaceutics in deciding drug delivery and dosage form. The paper presents the reader with a clearer insight into how important the above are, with extensive explanations into the three laws of thermodynamics and how they all help the modern day pharmaceutical scientist. Many of the complicated calculations involved in thermodynamics are exemplified through examples.
From the Paper
"A pharmacist is regarded as a professional scientist. Thus he is expected to know more than ever, is a thorough knowledge of thermodynamics. This discipline forms a rudimentary backbone of most of the material sciences as many other disciplines do ?borrow? heavily from this. 1,3 In studying thermodynamics, it attempts to integrate the factual knowledge of pharmacy and it aids the pharmaceutical scientist to predict the solubility, stability, feasibility, compatibility and biological action of drug products fairly accurately. Processes such as partitioning of solutes between immiscible solvents, the solubility of drugs, micellisation and drug-receptor interaction can all be treated in thermodynamic terms. 1Thermodynamics is concerned with the quantitative relationships between heat and other forms of energy, including mechanical, chemical, electric and radiant energy. 1The main feature to remember in the study of thermodynamics is that it is not possible to know the absolute value of the energy of a system but it is possible to record changes in energy that happen when a system undergoes transformation."

Abstract
This paper discusses the question of including thermodynamics in the study of economics. It is very important to include it when studying neo-classical economics and free-market activity because it alone seems capable of introducing consumption pattern analysis into the study of economics. Thermodynamics is important within ecological economics and within economics in general because the environment within which all economies function is anchored in a finite system that is constrained by its very nature and character.
From the Paper
"Resources are limited and many are not reproducible in any type of practical natural sense that would allow even sustainable growth models to be applicable. Petroleum will eventually be completely depleted and the natural process of producing it is simply not a practical option that would result in sustainable consumption patterns. "

Abstract
This paper contends that thermodynamics can be used as a guide to explain living systems because living systems are simply a manifestation of components of non-living systems, with atoms, elements and an injection of micro-electricity guiding the process. The author points out that this relatively simple assumption has guided years of research and allows scientists to create explanations, which employ thermodynamics to define the development and more importantly the creation of life. The paper relates that a conflict occurs when the biological systems lean in the direction of complexity, as all living systems do, and the human mind then falters in his or her ability to apply thermodynamic laws to living systems. The paper includes a formula and several long quotations.
From the Paper
"Within this driving force of potential complexity and also the inability of simple science to correct for unpredictability there is debate, the driving force of answers. Debate ensues among those who attempt to simplify matters into those which can be recreated and documented repeatable effects to create scientific truth and those who wish to make conjecture part of the scientific rule on this issue. Some would say that the groundhog example is explainable through science, and still others would contend that it is not the environment that determines the reality of the system, ..."

Abstract
This paper discusses unsustainable consumption patterns and the laws of thermodynamics. It discusses the relationship between thermodynamics and the study of neo-classical economics and free-market society and its importance in the current economic model. Finally, the paper examines why ecological economics is antithetical to neo-classical economists and free market advocates and then discusses the need for further research on the topic.

From the Paper
"The first law of thermodynamics is the law of conservation and this law is critical in the establishment of sustainable consumption patterns within a free-market economy that rejects all forms of constraints (Lawn pars.2-5). Although this law states that energy cannot be destroyed or created it illustrates that materials that result in energy can be depleted through transformation processes that result in forms of energy that cannot be harvested in an economic sense. Entropy is essentially the second law of thermodynamics and as such is central to thermodynamics as it is applied to ecological economics. Entropy is the concept in ecological economics that describes the state of potential energy as being less than the initial energy contained within an item or unit (Finch & McMaster 135). It describes the necessity of continually introducing new energy into economic activity to produce ever greater results or outcomes at the risk of economic shutdown."

Abstract
This paper uses the second law of thermodynamics to explain why a properly designed source-separation recycling program takes less energy and produces less pollution than a centralized program that collects mixed waste over a large area and hauls it to a centralized facility where workers or machinery separates the waste for recycling.
From the Paper
"Waste is an unavoidable consequence of our consumer oriented, highly industrialized society. In 2000, Canadians generated 1021 kg of non-hazardous waste per capita (Statistics Canada, 2002). 747kg of this waste were disposed of per capita (Statistics Canada, 2002), while the rest was recycled. Torontonians for example recycled 699 tonnes of household waste in 2001 (Ministry of Environment, 2004). Household waste generation was 353kg per capita in 2000 (Statistics Canada, 2002). The situation is similar in most developing countries although the levels of recycling vary. Growing concern for the environment, constant increase in the amounts of waste produced, economic, land and social costs involved in developing new landfill sites and public opinion have brought about the need to approach waste management in a broader context.

From the Paper
" By the last few decades of the nineteenth century, theoretical physics was entering a state of crisis.. This crisis, which reached its culmination about the turn of the century, was due to several factors. New discoveries, some quite accidental (such as that of X-rays) made physicists aware of previously unimagined form of radiant energy..
In addition, the development of precise means of measurements allowed experimental confirmation to be sought even for extremely subtle effects, which previously would have remained in the domain of theory alone.. For example, the luminiferous ether, through which light was supposed to move, was widely assumed to exist by nineteenth century physicists. Once its effects became measurable, experimentalists sought to identify them--and failed to find them, triggering a crisis.."

From the Paper
"Osmosis is the process of diffusion of water molecules across a membrane. The contents of cells are basically solutions of many different solutes and the more concentrated this solution is the more solute molecules there are in a given volume and the less water molecules. Water molecules can diffuse freely across a membrane but only down a concentration gradient so water always diffuses from a dilute solution to a more concentrated solution. Osmosis can be quantified using water potential so it is possible to calculate ... "

The Kalam Cosmological Argument, 2006.
An analysis of the Kalam cosmological argument of William Lane Craig.

»

Abstract
This paper discusses how William Lane Craig has created a simplified tree-system in which he breaks the universe down into having a beginning that was caused by a personal being. The paper then looks at how Craig provides four arguments as evidence to backup his notion and examines how the first two arguments are philosophical and are intertwined with the concept of infinity. Next, the paper examines how Craig's last two arguments are scientific dealing with the expansion of the universe and thermodynamic evidence that the universe used to be infinitely small.
From the Paper
"Morrison provides an objective voice to Craig's evidence. Morrison knows that infinity can exist in reality. A hypothetical library with an infinite amount of books is ridiculous in reality, but there are other things, which truly are infinite (p.96). There is the matter of Euclid's Maximum, it says nothing about the number of elements, and Craig makes the false assumption that since it does not work for infinity, then infinity cannot exist (p.97). Morrison argues that things such as space, numbers, of division of sub-regions are infinite. Our space is ever expanding, and be it a closed or open system, it will still be infinite. We know that there exist an infinite sub-numbers between any two numbers (eg. Numbers 1 to 2). If a person where to walk to a destination, at one point he would get to a half-way point, then from that point he would have to get to another half-way point, and another, and so on. "

From the Paper
"The second work that Gibbons published in the same year was "A Method of Geometrical Representation of the Thermodynamic Properties of Substances by Means of Surfaces". From the years from 1876 to 1878, Gibbs published two memoirs, which were later to be combined into one work, entitled, "On the Equilibrium of Heterogeneous Substances". Added to this, Josiah Willard Gibbs has contributed to various other spheres, like for example, crystallography, the determination of planetary and comet orbits, and also to electromagnetic theory. The most interesting phenomenon that Gibbs managed to achieve was that he made the practical side of science appealing and fascinating. Gibbs was also recognized as a 'theoretical physicist' of international stature, and he received a patent in the year 1866 for an improved type of railroad brake."
