Estimating phytoplankton growth rates from compositional data
I build on the deterministic phytoplankton growth model of Sosik et al. by introducing process error, which simulates real variation in population growth and inaccuracies in the structure of the matrix model. Adding a stochastic component allows me to use maximum likelihood methods of parameter …

The Linear Growth Rates of Pentaerythritol Crystals
The linear growth rates of the (101) faces of single crystals of Pentaerythritol (Pe) in aqueous solutions have been measured as a function of temperature (10-50°C), and concentration difference (0.25 x 10° acs 2.60 x 10-2 KgPe/Kg Solution) under stagnant conditions in a batch cell. The effect on …

Hierarchical Bayesian Analysis of Peruvian Tree Growth Rates
… to analyze massive data sets of Peruvian tree growth data. The study is important in finding connections between different parameters (such as the tree's classification or elevation) and rate at which the tree grows. We combine the Bayesian paradigm with the hierarchical structure of our data …

Antarctic sea ice phytoplankton growth rates and survival mechanisms
Phytoplankton play an important role in the Southern Ocean food web being the primary producers of food, particularly in winter, and partaking in the uptake of CO2 from the atmosphere via photosynthesis. Despite being photosynthetic organisms, phytoplankton survive at the bottom of sea ice where …

Historical growth rates and changing climatic sensitivity of boreal conifers
… with the expression of relatively long-timescale growth forcing in tree-ring chronologies. The operation of different standardisation techniques, used in dendroclimatology to remove internal, non-climate related growth trends in measured series of ring-widths, is explored with an emphasis on the …

The Effects of Socioeconomic Status on Growth Rates in Academic Achievement.
… study was to examine the differences in academic growth rates as demonstrated on the TAKS test among students based on those who received free lunches, those who received reduced-price lunches, and those not economically disadvantaged. Texas Assessment of Knowledge and Skills (TAKS) for reading …

Growth Rates of Curriculum-Based Measurement-Written Expression at the Elementary School Level
… project appears to be the first to determine growth rates for writing using Curriculum-Based Measurement-Written Expression (CBM-WE). Growth rates, or the amount of change over time, help educators track how much progress can be expected given typical instruction. CBM-WE probes were …

The effect of rumen inoculation on the growth rates of calves and lambs
Three commercially prepared rumen cultures and fresh rumen liquor were compared to determine their effect on the rate of gain and efficiency of feed utilization of a) twenty-four steer calves, b) twenty-four two-year old steers in pasture, and c) twelve weanling lambs. Two of the cultures were …

Influence of Winter Housing Conditions on Growth Rates and Feed Consumption of Dairy Heifers
… management to maintain steady and continuous growth of heifers and thereby secure properly developed cows which will give the production that is expected of them when they are brought into the milking herd. In general, heifer calves during the first twelve months of their growing period are …
