The paper is oriented on the hygrothermal microclimate of residential interiors in reconstructed building. The questionnaire survey has showed significant increase in number of allergies, respiratory diseases and occurrence of fungi after reconstruction. In order to find causes, experimental measurements of hygrothermal microclimate were carried out. The long term high values of relative humidity were found out and the link with number of efficient natural ventilation was searched for. Ventilation once a day was usual, what was proved as insufficient. Dwellers were informed about right way and number of ventilation. Furthermore, measurements proved decrease of air humidity, but not sufficiently. It was proved that nobody was able to achieve recommended number of ventilation and almost all of them considered it annoying and unreal to sustain. The biggest problem was proved night 7 hour interval. Therefore allergic and respiratory problems were significant in the morning. In conclusions of paper is suggestion for solution of researched problem.

Direct Measurements

This paper presents a study of thickness deformation of the viscoelastic material in constrained layer damping (CLD) treatments. The first goal of the study is to demonstrate the feasibility of using direct measurement to investigate thickness deformation in CLD treatments. The experimental setup consisted of a constrained layer beam cantilevered to a shaker, an accelerometer mounted at the cantilevered end, and two laser vibrometers that simultaneously measured the responses of the base beam and the constraining layer, respectively, at the free end. A spectrum analyzer calculated frequency response functions (FRFs) between the accelerometer inputs and the vibrometer outputs. Measured FRFs of the base beam and the constraining layer were compared to detect thickness deformation. Experimental results showed that direct measurements can detect thickness deformation as low as 0.5 percent. The second goal is to evaluate the accuracy of a mathematical model developed by Miles and Reinhall [7] that accounts for thickness deformation. FRFs were calculated by using the method of distributed transfer functions by Yang and Tan [13]. Comparison of the numerical results with the experimental measurements indicated that consideration of thickness deformation can improve the accuracy of existing constrained layer damping models when the viscoelastic layer is thick.

Amblyomma rotundatum is an ixodid tick that infests ectothermic animals and reproduces exclusively by parthenogenesis. This tick has been frequently reported to infest reptiles and amphibians, under natural conditions and sometimes in captivity. It was described in Brazil and several other countries of South, Central and North America. Although many studies have reported aspects of its biology, none of them has used regularly either ophidian as hosts, or controlled temperature, humidity and luminosity for parasitic stages. The objective of this experiment was to study the life cycle of A. rotundatum feeding on Viperidae snakes under room controlled conditions at 27 ± 1 ºC temperature, 85 ± 10% relative humidity and 12:12 hours photoperiod for parasitic stages, and under B.O.D incubator conditions at 27 ± 1 ºC temperature, 85 ± 10% relative humidity and scotophase for non-parasitic stages. The total duration of the life cycle ranged from 56 to 163 days (mean of 105 days). Two-host life cycle was observed for most of the ixodid population studied.

Survival of hydrilla (Hydrilla verticillata Royle) plants and propagules after removal from water and desiccation under controlled conditions were studied. Both apical and sub-apical sections of hydrilla plants were physiologically alive after drying for 16 h at 30 C and 40% relative humidity. Tubers survived drying conditions longer than turions. There was 16.7% sprouting in tubers that had been dried for 64 h, while percent sprouting of turions decreased sharply as the drying period increased from 0 to 8 h.

Cation-disordered Zn(Cu)–Si–P family materials demonstrate better Li-storage performance than the cation-ordered ZnSiP2 phase due largely to faster electronic and ionic conductivity and better tolerance to volume change during cycling, as confirmed by DFT calculations and experimental measurements.

The World

The hide beetle, Dermestes maculatus Degeer, is a cosmopolitan insect which each year causes considerable losses to stored products throughout the world. The economic importance of this species is due especially to the habit which the mature larvae have of boring into many commodities in order to pupate. However, the larvae and adults also feed on and thus damage a wide variety of substances with a high protein content (4), e.g., bones, carcasses, skins and hides of all kinds, etc.
