INFLUENCE OF CONGRESS IN SUPPORTING ON ENVIRONMENTAL ISSUE IN RONALD REAGAN ADMINISTRATION

This research aims to analyze the influence of the United States Congress in influencing the policies of the Ronald Reagan administration in ratifying the Montreal Protocol. This research uses one of the models proposed by Graham T. Allison, a bureaucratic political model. This model is used to analyze the political process associated with the bargaining position and compromise between the actors involved in the governments of Ronald Reagan, Congress and DuPont (the company). To understand how these actors play their role in the domestic political process, researchers use qualitative research by collecting data in the form of books, journals and other documents. Explorative methods are used to explore related argumentative basics related to the political process that occurs between the three actors. The result of this study shows that Congress in the era of the Ronald Reagan administration, especially in the House of Representatives is more dominated than the Democratic Party than the Republicans, while in the Senate during 1981-1989, the Democratic Party was only dominant in 1987-1989. The important three things in this research that all actors obtained their interests. Firstly, it is DuPont Company. It received benefits from CFC (Chlorofluorocarbon) changing such as HFC (Hydrofluorocarbon), HC (Hydrocarbon), and PFC (Perfluorocarbon). Secondly, it is Congress Agency. It which was dominated by the members of Democratic Party that stressing on environmental issues could reach their political program such as environmental protection. Thirdly, it is the Executive Agency. It gained benefits in saving of budget $503 million up to $2,8 billion for treating many diseases such as cortical cataract cancer, decrease of body immunity, and environmental problems.

New kind of Cu based paste for Si solar cells front contact formation

Potential impact of copper replacing silver in the paste used for the front electrode fabrication in crystalline silicon solar cells was investigated. The copper was applied as a new CuXX component with about 2 wt.% to 6 wt.% share of XX modifier. The generated CuXX molecules were analyzed using transmission microscopy. Based on the commercial Du Pont PV19B paste, CuXX and XX materials, the new PV19B/CuXX paste with 51 wt.% share of Cu and the PV19B/XX paste with 51 wt.% share of XX only were developed. Comparative studies of the effect of the commercial PV19B paste made by DuPont Company, and the pastes with the CuXX component and with the modifier XX alone on the electrical parameters of solar cells produced on crystalline silicon were carried out. The solar cells were characterized by the current-voltage technique. As a final result, the Cz-Si solar cell with the 51 wt.% share of Cu in the front electrode having a series resistance of 0.551 Ω·cm2, an efficiency of 14.08 % and, what is more important, the fill factor of 0.716, was obtained. It is the best result ever obtained concerning direct Cu application for solar cells fabricated in thick-film technology.

Aqueous biological graphene based formulations for ink-jet printing

The aim of the study was to produce heterophasic graphene nanoplatelets based formulation designed for ink-jet printing and biomedical applications. The compositions should meet two conditions: should be cytocompatible and have the rheological properties that allow to apply it with ink-jet printing technique. In view of the above conditions, the selection of suspensions components, such as binder, solvent and surfactants was performed. In the first stage of the research the homogeneity of the dispersion of nanoplatelets and their sedimentation behaviour in diverse solutions were tested. Subsequently, the cytotoxicity of each ink on human mesenchymal stem cells was examined using the Alamar Blue Test. At the same time the rheology of the resulting suspensions was tested. As a result of these tests the best ink composition was elaborated: water, polyethylene glycol, graphene nanoplatelets and the surfactant from DuPont company.

Analysis of Unsafe Acts in Mine Roof Accident and Prevention Measures

According to the research of Heinrich, DuPont Company and U.S. National Security Council, more than 80% of accidents are caused by individuals’ unsafe acts. In order to eliminate unsafe acts causing mine roof accidents, 10 types of common unsafe acts were summarized and 4 kinds occur most frequently based on 40 typical roof accidents, these 4 kinds of common unsafe acts are not choose the right work methods(20%), not prevent unsafe acts of others(17.5%), not check the environment(15%), nobody observe roof while working(12.5%). And then, corresponding safe acts are given. Finally, 4 types of improving measures are proposed, they are unsafe acts demonstration via 3-D animation, virtual reality training, unsafe acts knowledge contest and pithy formula teaching.

Preface

The 14th International Conference on Polymers and Organic Chemistry (POC 2012) was held 6-9 January 2012 in Doha, capital of the State of Qatar. This conference followed the 13th edition of this series, which was held in Montreal, Canada in 2009, and is a biannual meeting that travels from one continent to another since its inception in 1982 in Lyon, France to discuss recent results in the fields of polymer and organic chemistry in order to promote their importance in our everyday lives. This was the first IUPAC-sponsored meeting ever in the State of Qatar and the first time this meeting (POC) took place in the Arab world since it was established. POC 2012 was a very successful event, attended by approximately 300 chemists from over 15 countries.The conference featured Dr. Robert H. Grubbs, Victor and Elizabeth Atkins Professor of Chemistry at the California Institute of Technology and 2005 Nobel Laureate in Chemistry, as keynote speaker. His lecture was titled “The synthesis of large and small molecules using olefin metathesis catalysts”.The conference consisted of eight oral sessions, which focused on:- Polyolefins (Chair: Dr. Abbas Razavi, Total Petrochemicals Research Feluy)- Responsive and smart polymers (Chair: Dr. David E. Bergbreiter, Texas A&M University)- Polymers in energy (Chair: Dr. Hiroyuki Nishide, Waseda University)- Polymers as therapeutics (Chair: Dr. Karen L. Wooley, Texas A&M University)- Advances in polymer synthesis (Chair: Prof. Brigitte Voit, Leibniz-Institut für Polymerforschung Dresden)- Orthogonal chemistry: organic and polymer synthesis (Chair: Dr. Craig Hawker, University of California Santa Barbara)- Macromolecular engineering with biomolecules (Chair: Dr. Hanadi F. Sleiman, McGill University)- Polymers from renewable resources (Chair: Dr. Joe Kurian, Dupont Company).In addition to the keynote lecture, the conference featured an impressive 43 invited lectures by prominent chemists from all over the globe. The oral sessions featured an additional 29 contributed talks. The poster session showcased the latest results presented by 71 faculty and students attendees.The organizers of the POC 2012 would like to thank the sponsors who generously supported this event. Qatar Petrochemical Company (QAPCO) was the premier sponsor. The organizers are also grateful to the following sponsors: Qatar Fertiliser Company (QAFCO), Qatar University, Qatar Foundation, Texas A&M University at Qatar, and Qatar Airways.I would like finally to acknowledge all the members of the POC 2012 Organizing Committee and International Advisory Committee for their immense contributions. Special thanks are extended in particular to Hala El-Dakak and G. Benjamin Cieslinski for their outstanding efforts.Hassan S. BazziConference Chair
