Plant parasitic nematodes on golf courses present special problems for both disease diagnosticians and superintendents. In contrast to fungal diseases, which are unacceptable at any level, low to moderate levels of plant parasitic nematodes should be expected in any stand of turf. The difficult part of managing a potential nematode problem is determining when the nematode population is actually...

With the (near-)availability of complete sequences of human and other genomes, research effort is turning from obtaining the sequence itself towards determining the biological function of the genes within the sequence. One approach, made practically feasible with the advent of DNA microarray technology, consists of clustering of genes into groups of coexpressed genes, i.e. genes exhibiting simi...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/ bcr-2015-213388 DESCRIPTION A 3-year-old boy presented with pigmented (brownish) macules on his hands (figure 1), left arm (figure 2) and face (figure 3). The lesions appeared days after the boy played with common rue and were best noticed after sun exposure. Topical treat...

Kelleher et al’s study is very interesting and raises some important questions, but we think that it also has some confounding factors that need to be addressed before conclusions are made. In addition, there are some methodological issues which we would like to be clarified. The response rate in study 1 is 52%, which might not be enough to support the conclusion of this kind of study. Second, ...

Various epilepsy surgery procedures can be used to cure or reduce seizure frequency. Most procedures are either designed to resect or disconnect the area of the brain where seizures originate or spread. Epilepsy surgery is a procedure that either removes or isolates the area of the brain where seizures originate. Epilepsy surgery can significantly improve seizure control in a carefully selected...

seed germination, is a new alternative to no-till in areas where poorly drained soils are dominant. Where soil moisture conditions are suitable, strip-tillage creates narrow-width tilled strips, traditionally in the fall, to increase early spring soil evaporation and soil temperature in the top 2 inches. This is particularly effective in poorly drained wet soils, where slightly raised soil stri...

The Cauchy-Davenport theorem states that for any two nonempty subsets A andB of Z/pZ we have |A + B| ≥ min{p, |A| + |B| − 1}, where A + B := {a + bmod p | a ∈ A, b ∈ B}. We generalize this result from Z/pZ to arbitrary finite(including non-abelian) groups. This result from early in 2006 is independent ofGyula Károlyi’s 2005 result in [13] and uses different methods.
