Predicting tree pollen season start dates using thermal conditions

Thermal conditions at the beginning of the year determine the timing of pollen seasons of early flowering trees. The aims of this study were to quantify the relationship between the tree pollen season start dates and the thermal conditions just before the beginning of the season and to construct models predicting the start of the pollen season in a given year. The study was performed in Krakow (Southern Poland); the pollen data of Alnus, Corylus and Betula were obtained in 1991–2012 using a volumetric method. The relationship between the tree pollen season start, calculated by the cumulated pollen grain sum method, and a 5-day running means of maximum (for Alnus and Corylus) and mean (for Betula) daily temperature was found and used in the logistic regression models. The estimation of model parameters indicated their statistically significance for all studied taxa; the odds ratio was higher in models for Betula, comparing to Alnus and Corylus. The proposed model makes the accuracy of prediction in 83.58 % of cases for Alnus, in 84.29 % of cases for Corylus and in 90.41 % of cases for Betula. In years of model verification (2011 and 2012), the season start of Alnus and Corylus was predicted more precisely in 2011, while in case of Betula, the model predictions achieved 100 % of accuracy in both years. The correctness of prediction indicated that the data used for the model arrangement fitted the models well and stressed the high efficacy of model prediction estimated using the pollen data in 1991–2010

A review of phase transitions in RbIn-molybdate

The paper gives a brief review of the results of EPR temperature studies of RbIn(MoO4)2 crystal. A sequence of several structural phase transitions has been found in this crystal in the temperature region 84–163 K. The transition at T1 = 163 K leads to an incommensurate triply modulated state, whereas ferroelastic phases start below T2 = 143 K. All the low temperature phases in the temperature region 84–143 K are examples of simultaneously ferroelastic and incommensurate ones. The transition observed at T5 = 84 K seems to suppress the ferroelastic properties of the crystal

Effectiveness of Yomesan in human teniosis

Yomesan proved to be highly effective against teniosis in people. It is easy to use and lends itself for ambulatory treatment, in contrast to Taenifuge, the effect of which was negligible

Sravnitel'nye issledovanija serologicheskikh ossobennostejj antigenov iz lichinok Trichinella spiralis izolorovannykh iz myshc krys, krolokov i svinejj

It might be concluded from the obtained results that no significant serological differences exist between the T. spirails antigens prepared from larvae deriving from muscles of rabbits, rats or pigs, when the methods applied in this study were used. All the three antigens showed the simillar ability of the complement fixation when tested against the rabbit immune sera as well as against those of persons suffering from trichinellosis. The antigens behaved also in the simillar way towards sera of normal persons and towards Ascaris, Echinococcus and Cysticercus immune sera. The results of present experiments do not confirm Gaase's opinion, who suggested that antigen prepared from. T. spiralis larvae isolated from muscles of swine are superior to these obtained from muscles of rats (2). Studies on larger material using other serological methods should be needed to drow out some more detailed conclusions

Vlijanie ACHT na reakciju uroprecipitacii pri trikhinelleze u krys

Investigations have been carried out on the effect of ACTH on the uroprecipitation reaction in trichinellosis. Some differences in the dynamics of the reaction between the infected rats, treated and untreated, have been demonstrated. However, the differences are statistically not significant
