Signals and Systems Group Uppsala University e-mail: [email protected] WWW: http://www.signal.uu.se Abstract | The use of array antennas in mobile telecommunication systems has proven to increase the spectral efficiency of the system. However, the use of anN element array antenna at the basestation site implies that the amount of radio hardware must be increasedN -fold. This will make bas...

A 3135 bp DNA segment downstream of the spl gene on the Bacillus subtilis chromosome was cloned and its nucleotide sequence determined. An open reading frame capable of encoding a putative protein of 654 amino acids with a calculated molecular mass of 72.1 kDa was identified. The deduced amino acid sequence was similar to the McpA and McpB proteins of B. subtilis. McpA and McpB encode different...

A cohort study was undertaken of 2119 workers from Denmark who were potentially exposed to phenoxy herbicides. The workers were from two factories that produced phenoxy herbicides since 1947 and 1951, respectively. They had been employed either in the manufacture of phenoxy herbicide or in the manual service functions. The main product was 4-chloro-2-methylphenoxyacetic acid (MCPA). From 1947 t...

The objective of this study was to compare ImiFlex rates and timings for efficacy crop response in imidazolinone-tolerant grain sorghum. Volunteer corn Johnsongrass control generally best when (imazamox) applied postemergence (POST), except tank mixed with Huskie (bromoxynil/pyrasulfotole). Likewise, Palmer amaranth most consistent POST. Though all herbicides increased yields relative the weedy...

Pesticides are extensively used in agriculture to prevent infestation of crops, control plant-associated diseases and pests, increase crop productivity. With regards typical agricultural practice, tank mixing two or more plant protection products the subsequent applications herbicides, fungicides, insecticides common application strategies improve pest control. Our study provides evidence that ...

Many inhibitors prevent the oxidation o f the primary electron-accepting quinone (QA) by the secondary quinone (QB) in photosystem II by displacem ent o f Q B from its binding site. On the other hand, plastoquinone-1 and 6-azido-5-decyl-2,3-dim ethoxy-/?-benzoquinone displace herbicides. Binding studies show the herbicide/quinone interaction to be (apparently) competitive. The herbicide binding...

68 Abstract Transgenic bromoxynil-, glufosinate-, and glyphosate-resistant crops have been commercialized and grown extensively in the Western Hemisphere and, to a lesser extent, elsewhere. Bromoxynil-resistant crops have been removed from the market. Few new herbicide-resistant crops (HRCs) are likely to be introduced in the near future. Glyphosate-resistant cotton and soybean have become domi...

Freshwater occurrences of the selective acid herbicide 2-methyl-4-chloro-phenoxyacetic (MCPA) are an ongoing regulatory and financial issue for water utility industries as number magnitude detections increase, particularly in surface catchments. Assessments mitigating pesticide pollution catchments used drinking sources require a combination catchment-based treatment solutions, but approaches l...
