[Identification of corpses in mass disasters]. / Sul riconoscimento di soggetti deceduti in seguito a disastri collettivi

Reference is made to an air disaster causing considerable loss of life near Palermo. The type of lesions noted on the bodies is described and the criteria adopted for identification and recognition in accordance with the present legislation are explained. The reasons for mistaken identification, some of them of a most unusual nature, are listed and their prevention is discussed. An examination is also made of some recent proposals concerning the avoidance of such errors in disasters involging large numbers of persons.

Polymorphism of erythrocyte malic enzyme in the goat.

Three electrophoretic variants of erythrocyte malic enzyme (ME) in goats were reported. Inheritance data indicate that they are controlled by codominant alleles. The allele frequencies in four Mediterranean populations are given.

A route to the total synthesis of iso-LTB4 system.

The convergent synthesis of the iso-Leukotriene B4 (XVI) (as diastereoisomeric mixture with the desired geometry), by Wittig's condensation of the two precursor synthons at 6 (VI) and 14 C (XIV), starting from the common cyclic acrylaldehyde dimer (I), is reported.

Lactation curves of Valle del Belice dairy ewes for yields of milk, fat, and protein estimated with test day models.

Test day models were used to estimate the lactation curves for Valle del Belice ewes and to study the main environmental effects on milk yield and on percentage of fat and protein. Environmental effects were treated as fixed. A random effect was associated with each lactation to evaluate the mean correlation among all test day records of an individual ewe. Lactation curves were constructed by adding solutions for classes of either days in milk nested within parity or days in milk nested within season of lambing to appropriate general means. Parity primarily affected the lactation curve for milk yield, which was lower and flatter for first lambing ewes; effects on fat and protein were smaller. Season of lambing affected all traits. Seasonal productivity had the greatest effect on milk composition, resulting in an imbalance between fat and protein percentages. Flock and feed supplementation affected only the lactation curve for milk yield. The lactation curve of Valle del Belice ewes stood at a relatively high level. However, the presence of notable, perturbative effects (environmental and random variation) on milk yield and composition suggests that management is unable to meet the requirements of ewes consistently.
