[1] The Luzon Strait transport, as an index for the South China Sea throughflow, has attracted much attention recently. In this study the interannual variability of Luzon Strait transport is examined, using the Island Rule and results from ocean data assimilation. Transport variability obtained from these two approaches is consistent with each other. Assessment of contribution from each integra...

We present a new empirical shoreline evolution model integrating longshore and cross-shore processes. It is designed for wave-dominated sandy coasts and includes feedback between shoreline and wave dynamics. It can also take into account non-erodible (e.g. rocks, artificial structures) contours and complex wave propagation patterns through the coupling with the spectral wave model SWAN. While t...

abstarct development of greenhouse gases in future periods not only causes change in average amounts of climate variables but also makes variables of this variability affected. then for sure concerning alternations followed with climate variables’ fluctuations and its average amounts in effecting on runoff would make more reliable results. in this inquiry initially fluctuations and average amou...

a bioequivalence study of two verapamil formulations (generic verapamil tablets and isoptin® tablets) was performed by comparing pharmacokinetic parameters of the parent drug and its major metabolite, norverapamil following a single dose administration of 80 mg verapamil hydrochloride in 22 healthy volunteers according to a randomized, two-period, crossover-design study. moreover, the feasibili...

there is a general consensus that climate change has impact on the intensity and frequency of rainfall events. however, very little research is available about the changes in short term rainfall extremes. the focus of this paper has been on the change in annual and monthly rainfall extremes in ontario. the results indicate a greater variability (increase and decrease) among stations for shorter...

retrotransposons (rtns) constitute informative molecular markers for plant species because of their ability to integrate into a multitude of loci throughout the genome and thereby generate insertional polymorphisms between individuals. in the present study, rtn-based molecular markers, irap (inter-retrotransposon amplified polymorphism) and remap (retrotransposon-microsatellite amplified polymo...

designing breeding programs for winter rapeseed (brassica napus l.) cultivars with improved seed and oil yields requires information about the genetic variability of traits. in this study, 28 winter rapeseed cultivars were evaluated for genetic variation and relationships between 11 agro-morphological characters during 2010 and 2011. cultivars and cultivar × year interaction showed significant ...

Survival analysis is applied to records for length of productive life of Angus cows, fitting several proportional hazards models. It is shown that a piece-wise Weibull model with a time-dependent stage effect can model the distinct annual culling pattern reasonably well. Analyses fitting a sire model suggest some genetic variability, with heritability estimates on the logarithmic scale ranging ...
