Purpose
Feral populations of cultivated crops can act as reservoirs for novel genetically engineered (GE) traits and aid in trait movement at the landscape level. However, little information is available on the potential of cultivated crops to become feral. In this study, we investigated the ferality of alfalfa populations (non-GE version) occurring in roadside habitats. Knowledge on the nature of roadside alfalfa populations would be useful for designing efficient trait confinement protocols and coexistence strategies in alfalfa. 相似文献12.

Overall, the deregulation of genetically engineered (GE) crops for commercial cultivation in North America has been a success
story. In several cases, however, GE crops have sparked concerns and disagreements among the stakeholders and there are incidences
of court lawsuits, including a recent one on glyphosate resistant (GR) alfalfa (Medicago sativa, L.). While GE crops can provide operational benefits to farmers, challenges are looming from commercialization of perennial
GE crops. The unique ecology and biology of these crops and GE alfalfa in particular can facilitate adventitious presence
(AP) of GE traits and it makes more visible that economic risks for conventional growers and food/feed producers have not
been adequately addressed by the GE regulatory system in the United States (US). Asynchronous market approvals and the existence
of a number of GE sensitive export markets create uncertainties among the exporters. Policy development in these fields may
be helpful for ensuring a broader acceptance and market success of GE agriculture in general. The analysis is focusing on
the US, although many diagnosed problems are also relevant to other jurisdictions—in particular if no co-existence policy
is in place. 相似文献

Design of Mass Exchange Network and Effluent Distribution System for effective water management 总被引:1,自引:0,他引:1
The environmental impact of industrial wastewater and higher cost of fresh water are the serious challenges faced by the process industries. It has led to the development of many new techniques to minimize fresh water consumption. Of the many approaches, which have been developed, the Water Source Diagram (WSD) is a flexible and dynamic alternative for the generation of different scenarios for the management of water networks with reduction in total consumption. In the present study WSD concept was coupled with water mains concept to mains simplify the piping network and reduce the cost. A new procedure was developed for integrating the effluent treatment processes to evolve Effluent Treatment Network. Example from literature having multi contaminants was considered. This simple procedure involving hand calculations will be a useful tool for process engineers to design water and effluent treatment networks. Also the WSD and ETN were combined to form an evolutionary WAMEN (Water Allocation and Mass Exchange Network) and the proposed WAMEN aims for minimum fresh water consumption. 相似文献
