Conditions driving chemical freeze-out

We propose the entropy density as the thermodynamic condition driving best the chemical freeze-out in heavy-ion collisions. Taking its value from lattice calculations at zero chemical potential, we find that it is excellent in reproducing the experimentally estimated freeze-out parameters. The two characteristic endpoints in the freeze-out diagram are reproduced as well.Comment: 8 pages, 5 eps figure

\u3ci\u3eEpinotia Nisella\u3c/i\u3e: an Unrecorded Host and Mode of Feeding (Lepidoptera: Tortricidae)

The larva of Epinotia nisella is best known as a feeder in female catkins of Populus, primarily P. tremuloides Michx. in North America. In Minnesota, adults were reared from larvae boring in current-growth branchlets of P. balsamifera L., with no sign of like infestation in neighboring P. tremuloides, which has thinner branchlets. The behavioral variance is explained as plasticity in feeding biology, a characteristic of insects utilizing host reproductive structures whose abundance is periodic

Weights of \u3ci\u3ePolia Grandis\u3c/i\u3e Pupae Reared at Two Constant Temperatures (Lepidoptera: Noctuidae)

Sibling Polia grandis (Boisduval) larvae were reared at two constant temperatures on fresh foliage of quaking aspen (Populus tvemuloides Michx.). Female pupae developing at 25°C were 24% heavier than those developing at 30°C and corresponding males were 32% heavier. Duration of the larval period averaged 51 days at the former temperature and 41 days at the latter. Based on other Lepidoptera, a 24% change in pupal weight affects fecundity by 28 to 130 eggs per female. Fluctuations in larval temperature regime might induce size and fecundity variation in natural populations of grandis and other Lepidoptera

\u3ci\u3ePammene Perstructana\u3c/i\u3e (Walker) (Lepidoptera: Tortricidae) Identified After More Than a Century

Sciaphila perstructana Walker has been known only from the female holotype, and Pammelle signifera (Heinrich) only from males. Based on associated males and females from the Great Lakes area. the two names apply to one species. The resulting synonymy leads to a new combination. Pammene perstructana, and finally associates a species with this long-battling specitlc name

Dashed Hopes; Broken Promises; More Despair: How the Lack of State Participation in the Medicaid Expansion Will Punish Americans with Mental Illness

This comprehensive study shows that 6.7 million uninsured people with a mental illness are currently eligible for coverage under the Medicaid Expansion that went into effect on Jan. 1, 2014. But the majority of these individuals with mental health conditions will be left out in the coverage cold due to their state's antagonism toward the Medicaid Expansion health insurance initiative

Annual Variation in Starting Date of Spring Feeding by the European Pine Shoot Moth in a Michigan Planting

New tents spun in five successive springs by the European pine shoot moth (Rhyacionia buoliana [Schiff.] ) in a Michigan planting of red pine (Pinus resinosa Ait.) occurred about 2 days later each year. This trend is believed due to habitat cooling as trees grow larger. In another planting feeding was more advanced on small trees than on large trees
