Using a global data set on egg hatch times in zooplanktonic and nektonic ectotherms from marine waters, the combined effects of body size, temperature and life-history attributes on development times were examined. After correcting for mass and temperature the mean egg hatch times (from laying to hatching) were 20 times faster in some taxa than in others. Some of the divergence in hatch times c...

Motivated both by the efficiency of the Hatch gain compared to the Kalman-type gain and the advantage of position-domain filtering compared to range-domain filtering, this paper proposes a position-domain Hatch filter for differential kinematic satellite-based positioning. A theoretically rigorous proof is provided to show that the Hatch gain generates a white residual sequence and is more effi...

Transient solutions of the equations for particle size distributions in a Brownian coagulation process have been obtained by the method of weighted residuals. The trial functions for expansion of the size distribution function were obtained by Gram-Schmidt orthogonalizafion of the set {n~} using an inner product with a weight function that was obtained by solving the equation of change with a c...

We examined understanding of linear measurement in 1st and 2nd graders from high-and low-SES families. Children made two kinds of errors on measuring objects not aligned with the beginning of the ruler reading off the number that corresponded to the rightmost edge of the object (common in low SES children) and counting the number of hatch marks that the length of the ruler encompasses (common i...

an experiment was conducted to evaluate the effect of feed restriction (fr) and meal feeding (mf) on performance, carcass characteristics and related parameters to ascites in ross 308 male broiler chickens. five dietary treatments were 1) the control (ad libo. feeding), 2 )feed restriction from 7 to 14 days (fr14), 3) feed restriction from 7 to 21 days (fr21), 4) meal feeding from 7 to 14 days ...

Different animal models have been used to study the effects of prenatal protein undernutrition and the mechanisms by which these occur. In mammals, the maternal diet is manipulated, exerting both direct nutritional and indirect hormonal effects. Chicken embryos develop independent from the hen in the egg. Therefore, in the chicken, the direct effects of protein deficiency by albumen removal ear...
