The Economic Impacts of GM Contamination Incidents on the Organic Sector

This paper examines the economic impact of GM co-existence on the global organic sector to date through GM contamination of organic food and crops. A total of 15 GM contamination incidents in the organic sector are identified, occurring either from cross-pollination from GM crops being grown in the area or due to contamination in the post-harvest supply chain. The financial losses incurred by organic farmers and food companies due to GM contamination are considerable, through lost markets, lost sales, lower prices, negative publicity, withdrawal of organic certification and product recalls. It is important that co-existence regimes address all of these impacts, with the GM sector being held accountabl

Synthesis of bio-based thermoplastic polyurethane elastomers containing isosorbide and polycarbonate diol and their biocompatible properties.

A new family of highly elastic polyurethanes (PUs) partially based on renewable isosorbide were prepared by reacting hexamethylene diisocyanate with a various ratios of isosorbide and polycarbonate diol 2000 (PCD) via a one-step bulk condensation polymerization without catalyst. The influence of the isorsorbide/PCD ratio on the properties of the PU was evaluated. The successful synthesis of the PUs was confirmed by Fourier transform-infrared spectroscopy and (1)H nuclear magnetic resonance. The resulting PUs showed high number-average molecular weights ranging from 56,320 to 126,000 g mol(-1) and tunable Tg values from -34 to -38℃. The thermal properties were determined by differential scanning calorimetry and thermogravimetric analysis. The PU films were flexible with breaking strains from 955% to 1795% at from 13.5 to 54.2 MPa tensile stress. All the PUs had 0.9-2.8% weight lost over 4 weeks and continual slow weight loss of 1.1-3.6% was observed within 8 weeks. Although the cells showed a slight lower rate of proliferation than that of the tissue culture polystyrene as a control, the PU films were considered to be cytocompatible and nontoxic. These thermoplastic PUs were soft, flexible and biocompatible polymers, which open up a range of opportunities for soft tissue augmentation and regeneration

Collective retaliation and the WTO dispute settlement system

Copyright @ 2009 The Estey Centre for Law and Economics in International Trade. Estey Centre Journal of International Law and Trade Policy is an open access journal.Article 22 of the Dispute Settlement Understanding (DSU) of the WTO offers, as last resort countermeasures, withdrawal of the concessions the state parties had agreed to in their schedules of commitments. The problem is that such a withdrawal of concessions would have very little impact on the economy and consequently on the behaviour of the respondent state if that party happened to be a developed state vis-à-vis a small, developing country. To deal with this situation a remedy of “collective countermeasures”, contained in Article 54 of the Draft Articles on State Responsibility of the International Law Commission (ILC), has been proposed; it has been argued that this remedy should apply, as a general principle of public international law, as a last resort in WTO disputes. The counter-arguments are, first, that the WTO regime is a self-contained regime and therefore the general principles of international law do not apply in this case, and, second, that the WTO legal system is based on a distinct idea of “compliance” with WTO rules as a primary remedy, as opposed to reparative and punitive justice. The concept of “compliance” with WTO rules is akin to the concept of “liberalization”, which is a linchpin of the WTO multilateral system. Therefore the idea of “collective countermeasures” or, in other words, “collective punishment” is repugnant to the principles of WTO law, and it is argued that the present remedies under Article 22 of the DSU are adequate

Formation of exoplanetary satellites by pull-down capture.

The large size and wide orbit of the recently announced exomoon candidate Kepler-1625b-i are hard to explain within traditional theories of satellite formation. We show that these properties can be reproduced if the satellite began as a circumstellar co-orbital body with the original core of the giant planet Kepler-1625b. This body was then drawn down into a circumplanetary orbit during the rapid accretion of the giant planet gaseous envelope, a process termed "pull-down capture." Our numerical integrations demonstrate the stability of the original configuration and the capture process. In this model, the exomoon Kepler-1625b-i is the protocore of a giant planet that never accreted a substantial gas envelope. Different initial conditions can give rise to capture into other co-orbital configurations, motivating the search for Trojan-like companions to this and other giant planets

MYTH AND REALITY:ORGANIC VS NON-ORGANIC

This report examines some of the key issues around organic food and its production. It takes up the challenge of answering the critics - critics who range from companies defending agri-business, through to the heads of national food authorities and some academics. It exposes the misleading and erroneous statements made against organic food, and provides the facts that proves them wrong

Study on waste from hospital and clinics in Phitsanulok

Waste generation depends on numerous factors such as established waste management methods, type of hospital establishment, hospital specialization, proportion of reusable items employed in hospital, and proportion of patients treated on a day-care basis. This study surveyed the waste from hospital and clinics in Phitsanulok and found the average daily waste generated as general, medical and hazardous waste from all hospitals in Phitsanulok Province at 1.751, 0.284 and 0.013 kg/bed respectively and at 0.323, 0.041 and 0.002 kg/bed respectively from all clinics in Phitsanulok Province. Medical waste from all hospitals consisted of needles, gloves, drain tubes, cottons and gauze, napkins, plastic syringes, swap and body parts with total daily generation at 0.452, 0.480, 0.390, 0.404, 0.018, 0.355, 0.004 and 0.382 kg/bed respectively. Information about proper waste management process is needed to improve hospital waste management. Hospital waste management is an important and necessary component of environmental health protection
