Cyclocephala colasi beetles are facultative endotherms that spend most of their adult lives inside the inflorescences of Philodendron solimoesense, where ambient temperature (T(a)) averages about 28 degrees C due to floral thermogenesis. Measurements of respiration within a range of T(a) showed that active beetles became spontaneously endothermic at T(a) below 28 degrees C but were rarely endot...

1. Six experiments, each involving two groups of six piglets, were designed to study the influence of environmental temperature on heat production, energy retention and protein and fat gain in early weaned piglets. Immediately after weaning, at a mean age of 25 d, the animals were raised in two open circuit respiratory chambers. Each chamber was equipped with a totally wired cage. The piglets w...

The effects of temperature on rates of cellulose synthesis, respiration, and long-term glucose uptake were investigated using cultured cotton ovules (Gossypium hirsutum L. cv Acala SJ1). Ovules were cultured either at constant 34 degrees C or under cycling temperatures (12 h at 34 degrees C/12 h at 15-40 degrees C). Rates of respiration and cellulose synthesis at various temperatures were deter...

The pattern of protein synthesis changes rapidly and dramatically when the growth temperature of soybean seedling tissue is increased from 28 degrees C (normal) to about 40 degrees C (heat shock). The synthesis of normal proteins is greatly decreased and a new set of proteins, "heat shock proteins," is induced. The heat shock proteins of soybean consist of 10 new bands on one-dimensional NaDodS...

The two Rome halo displays of 1629 and 1630 are prominent in the early halo literature, and the 1629 display is still cited today for having contained a 28 degrees circular halo. We have examined seventeenth century correspondence and publications in order to learn as much as possible about the existing documentation of the two displays. We find the documentation to be too weak to support a def...

Corn fermented with strains of Fusarium culmorum NRRL 3288, F. poae NRRL 3287, F. moniliforme NRRL 3197, and F. nivale NRRL 3289 at 28 degrees C for 13 days was refused when fed to 30- to 60-pound (about 13.6- to 27.2-kg) swine. Analyses of the refused corn for trichothecenes (T-2, HT-2, acetyl T-2, fusarenon-X, and vomitoxin) showed that only the corn fermented with F. culmorum contained vomit...
