The aim of the study was to evaluate the effect of storage and temperature on egg physical quality in Hyline chickens line. A total of 150 eggs from College of Natural Resources farm were sampled for the present experiment. About 70 eggs each were stored in home refrigerator (temperature, 7.46±0.23 ˚C; relative humidity, 24.80±0.05%) and room temperature (temperature, 22.98±1.12 ˚C; relative hu...

Peak oil” refers to the future decline in world production of crude oil and to the accompanying potentially calamitous effects. The majority of the literature on peak oil is non-economic and ignores price effects even when analyzing policies. Unfortunately, most economic models of depletable resources do not generate production peaks. I present four models which generate production peaks in equ...

While world oil production and reserves have been increasing since 1859, ‘peak oil’ analysts claim that production is on the cusp of a period of sustained decline. I first subject the peak oil model to a number of robustness tests. The peak oil assumption of a linear relationship between the ratio of production to cumulative production and cumulative production is rejected using data from diffe...

introduction: lactation yield and persistency are two economic important traits in dairy cow. the production level of a dairy cow is determined by a joint effect of genetic and environmental factors.the main factors determining the total amount of milk production are milk yield at the peak of lactation and persistency as well as length of lactation period. persistency are defined as a extent to...

Several attractive theories predict the existence of mirror fermions. There is a good theoretical reason to expect that the lightest mirror fermions might have relatively long lifetimes. We explore the experimental consequences of such a possibility, focusing on mirror lepton production at the SLC near the Z” resonance. We find that by going slightly off resonance or by polarizing the electron ...

Cell metabolism can vary considerably over the course of a typical fed-batch antibody production process. However, the intracellular pathway alterations associated with various phases of growth and antibody production have yet to be fully elucidated using industrially relevant production hosts. Therefore, we performed (13)C labeling experiments and metabolic flux analysis (MFA) to characterize ...
