Mussel Density

Cultivated mussels (Perna perna) were studied to test for the effects of cleaning on their growth. These effects were examined by experimentally cleaning mussels and by changing mussel density. Treatment was performed twice, at two and four months after immerging the ropes. Two months after the first treatment and three months after the second treatment, mussels were harvested and measured (weight, length, width and thickness). Analysis of variance showed that none of the treatments resulted in increased growth of the mussels, nor did increased density result in decreased growth when compared with the control. It was concluded that it was not necessary to clean the shells to increase harvest.

AbstractBiatora meiocarpa (Nyl.) Arnold (Lecanorales, lichenized Ascomycotina) is described and compared with some of its relatives, particularly B. helvola Körber ex Hellbom (syn. Lecideahelvola), a species with which it has often been confused. Biatora meiocarpa and B. helvola differ in (1) width of the paraphysis tops, (2) hymenium height, (3) apothecium width, (4) gelatinization of the paraphyses, (5) composition of the excipulum (hyphae with ellipsoid or shortly rectangular lumina in B. meiocarpa, narrowly linear lumina in B. helvola), (6) chemistry (1-2 triterpenoids or no substances in B. meiocarpa, gyrophoric acid plus 1-2 triterpenoids in B. helvola), and (7) length and shape of conidia. The variation in the first three characters overlaps but one–way analysis of variance (ANOVA) shows that B. meiocarpa and B. helvola differ significantly in each of these characters. Three further characters were subjected to ANOVA: spore length, spore width and length/width ratio of the spores. No statistically significant differences were observed in these characters.Biatora meiocarpa generally occurs on smooth bark of broad–leaved trees and shrubs. It is known from northern Sweden, Finland, and northwestern Russia

Abstract This study investigated the biometry, pre-germination treatments and substrates for the germination of diaspores of Balfourodendron riedelianum. The diaspores were characterized during germination according to their length, width, thickness, thousand kernel weight (TKW) and water content. Dormancy overcoming was tested by diaspore scarifying with sandpaper, sulfuric acid immersion, water and water at 100 °C; together with the control (untreated), they were associated to different substrates (including paper (EP), sand (EA) and vermiculite (EV). Germination tests were conducted in a germination chamber at 25 °C. The physiological quality of seeds was performed through the first count, germination and germination speed index (GSI). Biometric data were analyzed in frequency classes and the pre-germination treatment by analysis of variance. Diaspores are on average 18.59 mm long; 9.03 mm wide and 9.38 mm thick. The treatment of immersion in cold water for 48 hours and the substrate vermiculite (EV) were effective to overcome dormancy and recommended for germination tests.

Morphological Differences

It has been demonstrated that cross sections of bundles of hair can be effectively studied using image analysis. These studies can help to elucidate morphological differences of hair from one region of the body to another. The purpose of the present investigation was to use image analysis to determine whether morphological differences could be demonstrated between male and female human Caucasian terminal scalp hair.Hair samples were taken from the back of the head from 18 caucasoid males and 13 caucasoid females (Figs. 1-2). Bundles of 50 hairs were processed for cross-sectional examination and then analyzed using Prism Image Analysis software on a Macintosh llci computer. Twenty morphological parameters of size and shape were evaluated for each hair cross-section. The size parameters evaluated were area, convex area, perimeter, convex perimeter, length, breadth, fiber length, width, equivalent diameter, and inscribed radius. The shape parameters considered were formfactor, roundness, convexity, solidity, compactness, aspect ratio, elongation, curl, and fractal dimension.

This study examines the expression of selflessness – the tendency to ignore one’s own needs and serve others’ needs – in Rorschach protocols of women suffering from anorexia nervosa. The protocols of 35 women suffering from anorexia nervosa were compared to 30 protocols of a psychiatric comparison group. A multivariate analysis of variance over five variables (AG, PER, PHR, COP, and GHR) was significant: Anorexic patients showed higher characteristics of selflessness compared to the psychiatric comparison group. These findings contribute to the validation of the Rorschach technique and to the clinical observation of selflessness in anorexic patients, and they emphasize specific characteristics in the treatment of anorexia nervosa patients.
