A single herbicide (Trimec or Strike 3 ) application in early season (March or April) was made to marginal areas around Þelds in 23-km test sites of the Mississippi Delta in 1999, 2000, and 2001. The herbicide was used to kill broadleaf weeds in the marginal areas that served as hosts for tarnished plant bugs, Lygus lineolaris (Palisot de Beauvois). The herbicide treatment caused a signiÞcant r...

In airframe technology, designs have become progressively more compact, to accommodate internal and external carriage by aircraft, launch tubes on warships or torpedo tubes in submarines. Propulsion has evolved from simple pulse jets, through turbojets and liquid propellant rockets or ramjets to the current mix of: turbojets for subsonic tactical cruise missiles, turbofans for subsonic strategi...

Th is paper analyses residents’ perceptions toward cruise tourism development and its externalities. Th e research involved a primary data collection in Messina, during the summer peak of the cruise season in 2011. A correspondence analysis on the local residents’ perceptions shows that residents have an overall positive attitude towards cruise tourism development with respect to social, cultur...

Herbicide, Diphenyl Ether, Peroxidation, Antioxidants Measurements of ethane and ethylene as indices o f in vivo lipid peroxidation and o f chemicallyinduced stress, respectively, were done on mustard seedlings (Sinapis alba), treated with oxyfluorfen[2-chloro-l-(3-ethoxy-4-nitrophenoxy)-4-(trifluoromethyl)benzene]. When seedlings were exposed to low light intensity o f 14 W /m 2, only stress-e...

A modification of the GLEAMS model was used to determine application windows which would optimise efficacy and environmental safety for herbicide application to a forest site. Herbicide/soil partition coefticients were determined using soil samples collected from the study site for two herbicides (imazapyr, K,=46, triclopyr ester, K,,=l038)andpublishedvaluesfortwootherherbicides(henarinone,K,=5...

The adoption of genetically modified (GM) crops has increased dramatically during the last 3 years, and currently over 52 million hectares of GM crops are planted world-wide. Approximately 41 million hectares of GM crops planted are herbicide-resistant crops, which includes an estimated 33.3 million hectares of herbicide-resistant soybean. Herbicide-resistant maize, canola, cotton and soybean a...

Combustion-based sources of shaft power tend to significantly penalize distributed propulsion concepts, but electric motors represent an opportunity to advance the use of integrated distributed propulsion on an aircraft. This enables use of propellers in nontraditional, non-thrust-centric applications, including wing lift augmentation, through propeller slipstream acceleration from distributed ...

Speed reduction strategies have proved to be useful to recover delay if air traffic flow management regulations are cancelled before initially planned. Considering that for shorthaul flights the climb and descent phases usually account for a considerable percentage of the total trip distance, this paper extends previous works on speed reduction in cruise to the whole flight. A trajectory optimi...

Studies were conducted in the period 2009-2011 in the experimental field of the Institute of Land Reclamation and Agricultural Mechanization – Sofia. The following treatments were used: a1 no herbicides with weeds (C0); a2 herbicide oxyfluorfen (Goal 2 E) at a rate of 250 ml / da; a3 herbicide oxyfluorfen (Goal 2 E) at a rate of 500 ml / da. The experiment was set up using long plots, three ver...

In many fisheries, particularly high seas fisheries, effort is controlled primarily by scaling estimated fleet capacity to available biomass. Capacity is traditionally estimated by relating inputs to outputs, with gaps between maximum harvest and actual harvest ascribed to technical inefficiency; precaution often dictates managing for maximum technical efficiency. I demonstrate that cruise-leve...
