It has been shown that in the twisted mass formulation of Lattice QCD at maximal twist large cutoff effects are generated when the quark mass becomes of O(aΛQCD). In general, these effects can be suppressed in two ways: either by choosing the critical quark mass in an “optimal way”, or by adding the Clover term to the twisted action. We investigate the second option by performing a quenched lat...

For nitrogen to be transferred from a legume to grass through hyphae of arbuscular mycorrhizal fungi (AMF), as reported for a number of grass/legume combinations, the two species should be linked by a common hyphal network, which gives rise to the question of host–fungus preference. To examine the relative preference of perennial ryegrass and white clover for co-existing AMF, two experiments, a...

This study evaluated the synergism between several P-solubilizing fungi isolates and arbuscular mycorrhizal fungi to improve clover ( Trifolium pratense) growth in the presence of Araxá apatite. Clover was sown directly in plastic pots with 300g of sterilized washed sand, vermiculite and sepiolite 1:1:1 (v:v:v) as substrate, and grown in a controlled environment chamber. The substrate was ferti...

Frankliniella bispinosa (Morgan) is the key pest of southern highbush blueberries ( Vaccinium corymbosum L. × V. darrowi Camp) in Florida. Thrips feeding and oviposition injury to developing flowers can result in fruit scarring that renders the fruit unmarketable. Previous studies have shown that flower thrips can disperse into cultivated crops from surrounding host plants. Therefore, the objec...

Red clover, known for its estrogenic activity due to its isoflavones content (biochanin A, genistein, daidzein and formononetin), was inoculated with the arbuscular mycorrhizal fungus Glomus mosseae. Once the symbiotic fungus was well established, plants were harvested and we determined the root and shoot dry weight as well as the P-content. In roots and leaves the levels of biochanin A, genist...

Quality is considered to be one of the most critical and widely discussed issues worldwide nowadays. It is considered to be one of the key factors that affect customer satisfaction. ISO 9000 standards are the most popular and formal quality management systems that help companies in identifying and meeting their customers’ requirements and expectations. ISO 9000 certification has become a prereq...

(1) Ramets of Trifolium repens were sampled from sites in a field of permanent pasture dominated by a mosaic of Lolium perenne, Holcus lanatus, Cynosurus cristatus and Agrostis tenuis. After multiplication of the ramets in a glasshouse, they were transplanted back into the original swards in all combinations of clover 'type' and site of origin. The pre-existing vegetation on the sites was eithe...

A field trial, a pot experiment and a survey in organically farmed leys were undertaken to investigate whether the N-fixation in red clover pastures in Norway was limited by a low supply of Co and/or Mo. Fertilization with Mo did not cause any higher production nor Nfixation, whereas the N-yield both from established clover leys and red clover grown in pots increased slightly after application ...

Cotton (Gossypium hirsutum L.) is an important fiber crop in Pakistan with significant economic importance. Transgenic, insect-resistant cotton (carrying a gene from Bacillus thuringiensis (Bt)) was inducted the cotton-based cropping systems of during 2002, and now sown >90% fields country. However, concerns are rising that Bt would decrease productivity winter crops (sown after cotton), lea...

We describe a way to optimize the chiral behavior of Wilson-type lattice fermion actions by studying the low energy real eigenmodes of the Dirac operator. We find a candidate action, the clover action with fat links with a tuned clover term. We present a calculation of spectroscopy and matrix elements at Wilson gauge coupling β = 5.7. The action shows good scaling behavior.
