The coarse aggregates used for Portland Cement concrete in southwest Iowa have exhibited a poor serviceability. This early failure is attributed to a characteristic commonly referred as "D" cracking. "D" line cracking is a discolored area of concrete caused by many fine, parallel hairline cracks. "D" line cracking is primarily caused by the movement of water in and through coarse aggregate with a unique pore structure. The presence of the water in the aggregates at the time of freezing causes the "D" cracking to occur and early failure. By making the pore structure less permeable to moisture, it is thought the durability factor of the concrete should increase. By drying the aggregate before mixing and then mixing with the cement, the particles of cement should enter the outer pore structure, and upon hydration make the pore structure less permeable to moisture.

In Switzerland from 1969-1985, 9 out of 11 influenza epidemics were associated with a statistically significant increase in mortality. A total of 12,202 excess deaths from all causes was identified. Expected deaths were forecast for each epidemic period separately for 4 age groups using Fourier and Arima modeling. 75.7% of all-cause excess deaths occurred in age group 70 to 89 and 5.1% in age group 1-59. In the 70-89 years old group the excess mortality risk during influenza epidemics was 271.6 per 100,000, whereas in age group 1-59 it was only 1.7 per 100,000. Only 40% of all excess deaths had been ascribed to acute respiratory conditions. Influenza viruses A H3N2 were the most frequently identified agents. In some instances mortality increased before the morbidity reports of the Swiss practitioners indicated the occurrence of an epidemic. Also, morbidity reporting decreased over successive years. A decrease in mortality following the epidemics was not observed. A more complete vaccination of high risk patients in Switzerland is desirable.

Aquest treball pretén, en primer lloc, analitzar la història del Centre d’Estudis de Llagostera. Durant les dècades dels quaranta, cinquanta i seixanta a les comarques gironines es creen un seguit de centres d’estudis amb la missió de fer recerca del passat a través de l’arqueologia. En segon lloc, pretén saber quina consideració tenia l’arqueologia després dels primers anys del règim franquista. En tercer lloc, es pretén estudiar com va renéixer l’arqueologia al municipi de la mà d’uns pocs membres cultes de la societat civil, la qual cosa ens permet esbossar com neixen les inquietuds pel descobriment dels orígens de la vila. En quart lloc, es pretén, recuperar la memòria oral mitjançant entrevistes a aquells membres cultes van que encara viuen al poble. El contacte amb aquestes persones que van estar immerses en el desenvolupament del Centre d’Estudis ha permès compilar alguns documents gràfics que posseïen alguns d’ells a les seves biblioteques particulars
