UNLABELLED BACKGROUND Patient reported menstrual history, physician clinical evaluation, and ultrasonography are used to determine gestational age in the pregnant female. Previous studies have shown that pregnancy dating by last menstrual period (LMP) and physical examination findings can be inaccurate. An ultrasound performed in the radiology department is considered the standard for determ...

Gibberellins are a class of terpenoid molecules that can act as plant growth regulators. This class was discovered through the investigation of sick rice plants that were infested by the fungus Gibberella fujikuroi. In 1926, Eiichi Kurosawa determined that a substance, dubbed gibberellic acid, secreted by the fungus was causing the disease. Subsequently, it was realized that gibberellic acid is...

BACKGROUND Resistance gene analogues (RGAs) have been isolated from many crops and offer potential in breeding for disease resistance through marker-assisted selection, either as closely linked or as perfect markers. Many R-gene sequences contain kinase domains, and indeed kinase genes have been reported as being proximal to R-genes, making kinase analogues an additionally promising target. The...

[1] The applicability of the Rayleigh-Gans approximation (RGA) for scattering by snowflakes is studied in the microwave region of the electromagnetic spectrum. Both the shapes of the single ice crystals, or monomers, and their amounts in the modeled snowflakes are varied. For reference, the discrete-dipole approximation (DDA) is used to produce numerically accurate solutions to the single-scatt...

In this paper the well-known Relative Gain Array (RGA) and the recently proposed Hankel Interaction Index Array (HIIA) are utilized for quantifying the degree of channel interaction in a multivariable bioreactor model, an activated sludge process configured for nitrogen removal. The HIIA can deal with plant structures where the RGA fails and can furthermore also be used to evaluate multivariabl...

We have identified an accession (LA2093) within the tomato wild species Solanum pimpinellifolium with many desirable characteristics, including biotic and abiotic stress tolerance and good fruit quality. To utilize the full genetic potential of LA2093 in tomato breeding, we have developed a linkage map based on an F(2) population of a cross between LA2093 and a tomato breeding line, using 115 R...

In recent years, it has been proved that vitamin K has important roles not only in blood coagulation but also in bone metabolism.i-i4) There are two types of vitamin K isolated from nature, vitamin Ki Cphylloquinone) synthesized mainly by plants, and vitamin K2 (menaquinone) rnade mainly by rnicroorganisms. Furthermore, there are fourteen kinds of menaquinone, depending upon the chain length of...
