Type Oscillation

Glycerol causes chemical oscillations in Belousov-Zhabotinskii reaction in a closed system as well as in a reaction solution bubbled with nitrogen. Since the oxidation of glycerol with bromate ions does not proceed autocatalytically and bromine in the oxidation state 0 or +1 in the absence of light does not react with glycerol, hydrolysis of bromine is the probable source of bromide ions in the studied oscillation system.

The geochemistry of detrital rutile grains, which are extremely resistant to weathering, was used in a provenance study of the transgressive Albian quartz sands in the southern part of extra-Carpathian Poland. Rutile grains were sampled from eight outcrops and four boreholes located on the Miechów, Szydłowiec, and Puławy Segments. The crystallization temperatures of the rutile grains, calculated using a Zr-in-rutile geothermometer, allowed for the division of the study area into three parts: western, central, and eastern. The western group of samples, located in the Miechów Segment, is characterized by a polymodal distribution of rutile crystallization temperatures (700–800 °C; 550–600 °C, and c. 900 °C) with a significant predominance of high-temperature forms, and with a clear prevalence of metapelitic over metamafic rutile. The eastern group of samples, corresponding to the Lublin Area, is monomodal and their crystallization temperatures peak at 550–600 °C. The contents of metapelitic to metamafic rutile in the study area are comparable. The central group of rutile samples with bimodal distribution (550–600 °C and 850–950 °C) most likely represents a mixing zone, with a visible influence from the western and, to a lesser extent, the eastern group. The most probable source area for the western and the central groups seems to be granulite and high-temperature eclogite facies rocks from the Bohemian Massif. The most probable source area for the eastern group of rutiles seems to be amphibolites and low temperature eclogite facies rocks, probably derived from the southern part of the Baltic Shield.

A case study of an odd rumor, widely current in China after Nixon's visit, is detailed. Based on interviews of respondents from Kwangrung and Fukien Provinces, an examination of the stabler aspects of this rumor not only points to its probable source, but also reveals two traditional components of Chinese national character.

SUMMARYIn one locality in Italy where the incidence of psittacosis has increased rapidly since 1980, a hospital-based study and a seroepidemiological survey were carried out in order to define the clinical and epidemiological features of psittacosis in that area.Registers of the Virology Unit of the University of Ancona, Italy, were reviewed and all hospitalized patients with a serological diagnosis of psittacosis were identified. A total of 76 cases were found and studied. A presumptive bird source was identified in 80% of 62 patients, on whom a detailed investigation had been possible. Poultry represented the most frequent probable source of infection. Clinically, the predominant pattern of illness was a moderately severe lower respiratory tract infection, with chest X-rays showing pulmonary shadowings in 68 patients (89%).In the seroepidemiological study, 51 out of 143 subjects were exposed to birds (35·7%), but only 7 out of 90 urban adult blood donors (7·3%) were positive for chlamydial antibodies using the microimmunofluorescence test.

Listeria monocytogenes was isolated from 4 reindeer calves as a nearly pure growth from several internal organs, pointing to a septicaemic form of listeriosis. The calves were born in a calving corral. Silage feeding was considered the most probable source of the infection.Abstract in Finnish / Tiivistelmä:Listeria monocytogenes -bakteerin aiheuttama verenmyrkytys poronvasoilla – tapausselostus Toukokuussa 2005 Suomen poronhoitoalueen kaakkoisosassa sijaitsevassa vasotustarhassa kuoli neljä poronvasaa pian syntymän jälkeen 5-11 päivän ikäisinä. Kaikkien vasojen kuolinsyyksi todettiin Listeria monocytogenes -bakteerin aiheuttama verenmyrkytys. Tartunnan todennäköisin lähde oli vaatimien lisäruokinnassa käytetty säilörehu. Kyseessä on ensimmäinen poronvasoilla todettu Listeria monocytogenes -bakteerin aiheuttama verenmyrkytys Suomessa.

Kalvene nedkom i en kalveinnhegning, og man antok at dårlig silofôr var smittekilden.

A number of polished thin sections from two cross sections within the Pindos foreland deposits were petrographically examined while microanalyses on certain minerals were carried out. Chemistry of these minerals is compared to analogous phases occurring in several formations in the neighbourhood of the studied areas which can stand as source areas. Our results reveal that the most probable source materials include the Pindos, Koziakas (and probably and Vourinos) ophiolite complexes, as well as metamorphic sequences of the Pelagonian Zone
