Opis:
The paper presents a computational analysis of the PMV, PPD and PD thermal environment indices for indoor air quality (IAQ) inside a historic wooden church in the village of Wiśniowa. The study is based on annual measurements of indoor air parameters as well as data on the number of Sunday Mass attendees and indoor air quality. As the results point out, indoor thermal comfort during the majority of Sunday Masses, both in summer and winter, remains within category C while the indoor air quality, assessed by means of PD index, levelled at 100%, irrespective of time of year. The improvement of inside air comfort and hygienic standards is possible by means of installing an effective mechanical ventilation system adapted for use in a historic building of high value in terms of local material culture.

Opis:
New particle formation and growth were observed at a coastal site (Preila station, Lithuania) during 1997 and 2000–2002. The total amount of data analysed covers 291 one-day periods, 45 (15%) of which were long-term, new particle formation days. Short-term nucleation events (from a few minutes to one hour) and long-term events (from one to eight hours) were identified. The mean particle growth rate, condensation sink and condensable vapour source rate during nucleation events were 3.9 nm h−1, 1.45 × 10−3 cm−3 s−1 and 7.5 × 104 cm−3 s−1 respectively. The average formation rate J10 was 0.4 cm−3 s−1. The nucleation events were accompanied mainly by air masses transported from the north (43%) and north-west (19%). Meteorological parameters and trace gas (O3, SO2, NO2) concentrations were also analysed. It was found that nucleation events are related to high levels of solar radiation.

Opis:
This paper analyzes whether physicochemical properties significantly influence the occurrence of zooplankton in a brackish reservoir. The studies were carried out on the Vistula Lagoon in August and September from 2006 to 2009 at 32 research sites. The environmental conditions in the Vistula Lagoon varied widely. At the time of the investigation, 17 species of rotifers, six species of Cladocera, and ten species of Copepoda were noted, and the total density of plankton fauna ranged from 145 to 765 ind. dm3. Statistical analysis demonstrated a significant correlation between the occurrence of some zooplankton species and certain environmental parameters, whereas the sampling sites were grouped according to study years. The zooplankton systems recorded at the research sites in 2006 constitute the most disparate group. Thus, it can be concluded that physicochemical properties might significantly impact both individual species (depending on their environmental demands) and entire zooplankton clusters.

Opis:
The study concerns the ecological responses of Tilia cordata Mill. to pollution and describes the advantages of estimating of the degree of environmental pollution. The aim was, to find out whether the degree of pollution conforms to the contents of the investigated elements in leaves, the assessment of variability of morphometric leaf traits and the cationic equilibrium values. The study has shown a statistically significant differentiation between the analysed sites in respect of dust fall, concentrations of elements in soils and leaves, morphometric traits of leaves and the cationic equilibrium. The hierarchical tree plot of cluster analysis qualified the sites as polluted and non-polluted. In polluted sites the contents of metals in leaves were significantly higher and the cationic equilibrium in leaves was disturbed. The surface, width and asymmetry of leaves, and also the variability of these measures were higher in polluted sites. In sites, which are not directly affected by pollution the cationic equilibrium is close to the const. value, whereas leaf traits have shown the lowest values and a considerably lower variability. The investigations show that leaf traits and cationic equilibrium correspond to the level of pollution and can be used as a tool for evaluation of the environment status.

Opis:
To examine the distribution of Trichodesmium relative to physicochemical factors during summer in the Changjiang (Yangtze River) Estuary and adjacent East China Sea shelf, three cruises were conducted separately in June 2009, July 2011, and August 2009. Trichodesmium species found were T. thiebautii, T. erythraeum, and T. hildebrandtii. The population was dominated by T. thiebautii, which accounted for >85% of the samples found. Most of them were free trichomes. Colonial forms were rarely observed (approximately 10% of our samples), occurring only in offshore waters. The depth integrated abundances of Trichodesmium were 308 × 103, 1709 × 103, and 3448 × 103 trichomes m−2 in June, July, and August, respectively. Trichodesmium was distributed abundantly in the southern or southeastern part of our study area, where nutrients were low and light penetration, temperature, and salinity were high, which were influenced by the Taiwan Warm Current (TWC) and Kuroshio. Trichodesmium was found in low abundance in inshore, eutrophic, low-salinity waters, which were mainly controlled by the Changjiang Diluted Water (CDW) and coastal current. These results suggest that spatiotemporal changes in the summer Trichodesmium distribution correlate highly with the variations in physicochemical properties that are primarily controlled by the TWC, Kuroshio, and CDW. The summer N2 fixation rate of Trichodesmium was estimated at 12.3 μmol N m−2 d−1 in our study area, contributing >50% of biological N2 fixation.

Opis:
The most prevalent P2P application today is file sha ring, both among scientific users and the general public. Afundamental process in file sharing systems is the search mechanism. The unstructured nature of real-world largescale complex systems poses a challenge to the search me thods, because global routing and directory services are impractical to implement. This paper presents a new antcolony algorithm, Adaptive Neighboring-Ant Search (AdaNAS), for the semantic query routing problem (SQRP) in a P2P network. The proposed algorithm incor porates an adaptive control parameter tuning technique for runtime estimation of the time-to-live (TTL) of the ants. AdaNAS uses three strategies that take advantage of the local environment: learning, characterization, and explo ration. Two classical learning rules are used to gain ex perience on past performance using three new learning functions based on the distance traveled and the resources found by the ants. The experimental results show that the AdaNAS algorithm outperforms the NAS algorithm where the TTLvalue is not tuned at runtime.
