Argument Map: Loewi's Argument That Neuro-Transmission Works With Chemical Signals Instead Of Eletrical (Short Version), Michael Hoffmann Dec 2014

Argument Map: Loewi's Argument That Neuro-Transmission Works With Chemical Signals Instead Of Eletrical (Short Version), Michael Hoffmann

Michael H.G. Hoffmann

This argument shows how the hypothesis that muscles are probably stimulated exclusively by chemical signals and not by electrical ones can be justified by Loewi's experimentum crucis.


Argument Map: Devoloping Scientific Hypotheses And Experimental Designs In Form Of An Argumentation. Loewi's Crucial Experiment On Chemical Neurotransmission, Michael Hoffmann Nov 2014

Argument Map: Devoloping Scientific Hypotheses And Experimental Designs In Form Of An Argumentation. Loewi's Crucial Experiment On Chemical Neurotransmission, Michael Hoffmann

Michael H.G. Hoffmann

This argument map presents Paul Loewi’s crucial experiment in which he showed that neural transmissions of signals are chemical in nature, not electrical, in form of an argumentation. The map can be used in science education to show how the formulation of hypotheses should be related to a corresponding determination of experimental designs.

Travelling In Cuba, Fathi Habashi Feb 2013

Travelling In Cuba, Fathi Habashi

Fathi Habashi

Contact with Cuban scientists was established in 1986 when two researchers from Centro de Investigaciones para Industria Minero Metalurgica in Havana visited Laval University to get acquainted with research activities in the area of extractive metallurgy. This was followed in early 1987 by two more researchers from the same centre. Invitations were then received in late 1987, 1989, and 2008 to visit the nickel refineries in Cuba and to hold seminars at the University of Havana. The present report outlines these activities.

The immersion of 362 student-interns has developed their …


Agrarian Reform And Philippine Political Development, Frede G. Moreno, Susana Evangelista Leones Jan 2012

Agrarian Reform And Philippine Political Development, Frede G. Moreno, Susana Evangelista Leones

Frede G Moreno

Landownership problem and control of resources remains as a political development issue in the Philippines. Agrarian reform is a necessary condition for agricultural modernization and rural industrialization and the fundamental mooring for global competition. Agrarian Reform has contributed to improvement of the socio-economic conditions of landless farmers and political development of the Philippines in terms of engaging the landless in the process of policy making and distribution of large private landholdings to the landless. Modalities giving peasants a stake in society such as decisive role in agrarian legislations, engaging them in dialogue to resolve agrarian cases, presenting manifesto pinpointing their …

Pyrite. History, Chemistry, And Metallurgy, Fathi Habashi Jan 2012

Pyrite. History, Chemistry, And Metallurgy, Fathi Habashi

Fathi Habashi

The Book covers the history of pyrite - - how it was a strategic mineral necessary for the production of elemental sulfur needed for making gunpowder for military purposes and for the production of SO2 needed for making sulfuric acid for the chemical industry. Now its presence is a nuisance in tailings ponds. The book also covers the processing of pyrite containing gold, its chemistry and technology, the processing of pyrite cinder for the production of a variety of metals, and its behaviour towards autotrophic microorganisms.

Do Ssds Extend The Conscious Mind?, Mirko Farina, Julian Kiverstein Jan 2012

Do Ssds Extend The Conscious Mind?, Mirko Farina, Julian Kiverstein

Mirko Farina

Is the brain the biological substrate of consciousness? Most naturalistic philosophers of mind have supposed that the answer must obviously be «yes » to this question. However, a growing number of philosophers working in 4e (embodied, embedded, extended, enactive) cognitive science have begun to challenge this assumption, arguing instead that consciousness supervenes on the whole embodied animal in dynamic interaction with the environment. We call views that share this claim dynamic sensorimotor theories of consciousness (DSM). Clark (2009), a founder and leading proponent of the hypothesis of the extended mind, demurs, arguing that as matter of fact the biology of …


De-Worming White-Footed Mice As A Strategy For Reducing Microparasite Transmission To Ticks, Stephanie Dunn Jan 2012

De-Worming White-Footed Mice As A Strategy For Reducing Microparasite Transmission To Ticks, Stephanie Dunn

Stephanie Dunn

This study applies the concept that disease dynamics involve multiple interacting factors and that a host organism’s immune response to simultaneous infections involves a system of tradeoffs. Past research has shown that chronic infection with intestinal worms has a negative impact on a host’s immune response to additional infection. The white-footed mouse (Peromyscus leucopus) is an excellent reservoir for the agents of Anaplasmosis, Lyme disease, and Babesiosis. P. leucopus passes microparasites to ticks at high rates. Thus, pathogen dynamics within this host are of major interest in the effort to prevent human infection. Here, we investigate the potential impact of …

Labor Unions And Climate Change, Jon Foster Dec 2011

Labor Unions And Climate Change, Jon Foster

Jon Foster

The challenge of climate change and the need for a shift to more ecologically sustainable methods of production and innovation can dramatically redefine the strategy and objectives of the labor movement as a whole. Furthermore, within the specific sectors of: Agriculture, Construction, Utilities, and Automobiles, the reality of a changing environment, and social views, has already begun redefining what the future of these industries will mean in relation to labor unions.

Embraining Culture: Leaky Minds And Spongy Brains, Julian Kiverstein, Mirko Farina May 2011

Embraining Culture: Leaky Minds And Spongy Brains, Julian Kiverstein, Mirko Farina

Mirko Farina

We offer an argument for the extended mind based on considerations from brain development. We argue that our brains develop to function in partnership with cognitive resources located in our external environments. Through our cultural upbringing we are trained to use artefacts in problem solving that become factored into the cognitive routines our brains support. Our brains literally grow to work in close partnership with resources we regularly and reliably interact with. We take this argument to be in line with complementarity or “second-wave” defences of the extended mind that stress the functional differences between biological elements and external, environmental …


The Study Of Social Sciences In Developing Societies: Towards An Adequate Conceptualization Of Relevance, Syed Farid Alatas Mar 2011

The Study Of Social Sciences In Developing Societies: Towards An Adequate Conceptualization Of Relevance, Syed Farid Alatas

farid alatas

Since the 19th century, there has been a strong awareness of a lack of fit between the western1 social sciences and non-western realities. Many examples of the irrelevance of western concepts, theories and assumptions have been noted in the literature. The fact that the social sciences emerged in the West, were initially practised in the Third World by colonialists and other European scholars, and then finally implanted among the locals during and after formal independence, had raised the question of the relevance of these bodies of knowledge to Third World societies and their problems. Some nonwestern scholars in the 19th …

Metalurgia Extractiva Y Política Nacional, Fathi Habashi Jan 2011

Metalurgia Extractiva Y Política Nacional, Fathi Habashi

Fathi Habashi

Should a country export its mineral wealth in form of concentrates or should it locally treat its ores to produce metals as final products? In the past centuries pyrometallurgy was the only route to extract metals from ores and this required a large capital investment many countries could not afford to raise. This situation encouraged marketing of concentrates. Today, metallurgists have the option to use the hydrometallurgical route to process ores and concentrates at a reasonable capital investment. This opened the way to the possibility of processing ores locally. When need arises to increase production new units can be added …

Leaching Mechanism Of Semiconducting Minerals, Fathi Habashi Dec 2010

Leaching Mechanism Of Semiconducting Minerals, Fathi Habashi

Fathi Habashi

The mechanism of leaching of semiconducting minerals such as PbS, ZnS, UO2, etc., has been the subject of intensive speculation by hydrometallurgists in the early 1950s. The electrochemical mechanism proposed in 1970 by the author in volume 2 of his Principles of Extractive Metallurgy avoids the assumption of forming intermediate complexes that cannot be isolated or identified.

Metals: Typical And Less Typical, Transition And Inner Transition, Fathi Habashi Mar 2010

Metals: Typical And Less Typical, Transition And Inner Transition, Fathi Habashi

Fathi Habashi

While most chemists agree on what is a metal and what is a non-metal there is a disagreement with respect to what is a metalloid and what is a transition metal. It is believed that this problem can be solved if two new terms are adopted: typical and less typical metals. These new terms will also help reconcile the European Periodic Table versus the North American regarding numbering of groups as well as the IUPAC numbering which could be as well abandoned in favour of group names as will be shown in the manuscript.


Phosphate Industry And The Radon Problem, Fathi Habashi Feb 2010

Phosphate Industry And The Radon Problem, Fathi Habashi

Fathi Habashi

The problem of radon generated during the treatment of phosphate rock by sulfuric acid to produce fertilizers can be solved by using nitric acid. In this case radium, which is the source of radon, goes into solution and can be precipitated by a controlled method and safely disposed of. A variety of options are discussed.
