Bazując na istniejącej sieci linii kolejowych w Polsce przeanalizowano połączenia dziesięciu największych miast Polski z Warszawą oraz ich konkurencyjność w odniesieniu do indywidualnego transportu samochodowego. Wykazano, że relacje: Bydgoszcz - Warszawa i Wrocław - Warszawa wymagają działań inwestycyjnych. Wyniki analizy mogą być przydatne w opracowaniu krajowego kolejowego programu budowlanego.

Based on the existing railway network in Poland this article examines connections of the 10 largest Polish cities with Warsaw and their competitive with individual transport. It has been proved that the connections: Bydgoszcz - Warsaw and Wroclaw - Warsaw require investment activities. The analysis results can be useful in the development of the national railway construction programme.

Problem of calculation of righting arms of the free-floating ship, i.e. longitudinally balanced at any heel angle, was formulated. In such a case of particular interest for a ship inthe damage condition, the righting arms are ambiguous as they depend on a way theheeling moment acts. Two cases were considered : when the heeling moment is parallel tothe ship plane of symmetry, and the case when it performs the least work, i.e. when themoment is parallel to the main axis of ship waterplane. It was demonstrated that angulartranslations (heel and trim) are then the Euler angles associated with a relevant referenceaxis. Some cases of the incorrect defining and using of those angles in today design practice were indicated. The most important features of the curve of righting arms of free-floating ship were demonstrated

This is the second part of the paper published in Polish Maritime Research no. 2/2005,dealing with the calculation problem of righting arms of the free-floating ship, i.e. longitu-dinally balanced at any heel angle. In such case the righting arms are ambiguous as theydepend on a way the heeling moment acts. Two cases were considered : when the heelingmoment is parallel to the ship plane of symmetry, and the case when it performs the leastwork, i.e. when the moment is parallel to the main axis of ship waterline. It was demon-strated that angular translations (heel and trim) are then the Euler angles associated witha relevant reference axis. Some cases of the incorrect defining and using of those angles in today designpractice were indicated. The most important features of the curve of righting arms of free-floating shipwere demonstrated

This paper presents the results on surface runoff and soil loss obtained in a model field experiment with simulated rainfall on loessial soil and its estimation with the CREAMS model. Satisfactory agreement between measured and simulated data was achieved.

W pracy przedstawiono wyniki uzyskane w modelowym doświadczeniu polowym z symulowanym opadem deszczu na glebie lessowej w celu weryfikacji modelu hydrologiczno-erozyjnego CREAMS. Dane zarejestrowane podczas procesu powstawania i przebiegu spływu i zmywu powierzchniowego porównano z danymi symulacyjnymi. Uzyskano zadowalającą zgodność pomiędzy danymi eksperymentalnymi a symulacją. Badany model umożliwia więc dobranie parametrów w celu oszacowania spływu i strat gleby dla danych warunków naturalnych.

We investigated annual height increment of sessile oak and common hornbeam planted on clear−cut in respect to the distance to the adjacent mature Scots pine stand. The study area was divided into 3 zones (I−III) each of 20 m width. The four analyzed treatments were defined on a basis of a mingling form: W1 – a monoculture of oak (control plot), W2 and W3 – two types of row mixture, W4 – single tree mixture. Two years after planting an annual height increment of both tree species was significantly higher in the zone I (adjacent to the mature pine stand from the SW side) than in two other zones. The same significant differences were also found at the other inventories. Although hornbeam was on average higher than oak, a growth inhibition of oak by hornbeam was not significant. The annual height increment of both species was correlated with the precipitation in June and July.

Celem artykułu jest zaprezentowanie najważniejszych aspek¬tów postrzegania pojęcia motywowania definiowanego w różnych kręgach kulturowych. Stanowi on, opartą o 'wybra¬ne pozycje literatury przedmiotu, analizę perspektyw Japonii oraz UE i USA w sprawie postrzegania motywacji, zatrud¬nienia, przynależności do organizacji oraz stylów zarządza¬nia. Autorzy starali się pokazać czytelnikowi wpływ japoń¬skich technik zarządzania na motywację pracowników Unii Europejskiej oraz Stanów Zjednoczonych Ameryki Północnej.

The purpose of this article is to present the most important aspects of the perception of the concept of motivating defined in different cultures. It is based on the selected items of litera¬ture, analysis of the prospects for Japan and the EU and the U.S. on the perception of motivation, employment, member¬ship in the organization and management styles. The authors tried to show the reader the impact of Japanese management techniques motivation in the European Union and the United States of America.

Dsb proteins control the formation and rearrangement of disulfide bonds during the folding of membrane and exported proteins. DsbA is an oxidant that catalyzes formation of disulfide bonds in newly synthesized, and yet unfolded proteins. In order to act catalytically again, it has to be reoxidized by a transmembrane protein DsbB characterized by two pairs of disulfides. DsbB is related to another protein family Dsbl, characterized by the presence of only one disulfide, and an additional C-terminal beta-propeller domain. The protein AAN82231 from E. coli strain CFT073 has been recently described as a new member of the Dsbl family (Grimshaw et al., 2008). It was found that AAN82231 forms a functional redox pair with DsbL - a newly described DsbA-like protein. Here, we report that AAN82231 shares no characteristic features with the Dsbl proteins. Instead, according to phylogenetic analyses AAN82231 clearly belongs to another, previously described subfamily of DsbB paralogs. To facilitate classification of DsbB and Dsbl homologs, we propose a new nomenclature system and present an updated phylogenetic analysis of the DsbB superfamily, which comprises the following families: "orthodox" DsbB, its paralogs now named DsbB2 (including AAN82231), Dsbl and two groups of so far uncharacterized DsbB paralogs termed DsbB3 and DsbB4. We have also developed a web server dedicated to phylogenetic assignment of DsbB/Dsbl candidate proteins that will be identified in the future.
