Opis:
Quantitative estimation of the structure - anticancer activity relationship in a series of macrocyclic Schiff bases of 2,6-bis(formylaryloxymethyl)pyridines was carried out by the topological approach. Correlation equations describing the relationship between the anticancer activity and structural parameters of the molecules studied and descriptors characterizing their structure were obtained on the basis of in vitro screening data. The influence of structure of the investigated substances as reflected by the parameters studied on the anticancer activity, was established.

Opis:
Almost unlimited possibilities of sharing neuroinformatics resources, opened by the Internet, create an almost unlimited number of issues. Growing amount of available data, combined with the lack of reliable and large enough metainformation resources, limits the proliferation and reliability of this media. In this paper we propose a solution, which may help in an efficient sharing of neuroinformatics resources, by means of a network of vortals dedicated to particular and well defined topics. These vortals are responsible for collection of high quality resources in their particular fields. They are interconnected in a way transparent to the user, using a low level interface for interchanging queries. For a user this means that a query entered in one of the vortals will return relevant results found also in the other vortals of the Network. We also describe technical details and pilot implementation; metainformation is based upon Open Archives/ Dublin Core standards, and interchange of queries on XML/SOAP.

Opis:
Many organizations today have more than very large data-bases; they have databases that grow without limit at a rate of several million records per day. Mining these continuous data streams brings unique opportunities, but also new challenges. This paper describes and evaluates VFDT, an anytime system that builds decision trees using constant memory and constant time per example. VFDT can in-corporate tens of thousands of examples per second using the-shelf hardware. It uses Hoeffding bounds to guar-antee that its output is asymptotically nearly identical to that of a conventional learner. The study VFDT's proper-ties and demonstrate its utility through an extensive set of experiments on synthetic data. To apply VFDT to mining the continuous stream of Web access data from the whole University of Washington main campus.

W pracy przedstawiono wyniki badań wytrzymałości na ścinanie mieszaniny popiołowo-żużlowej pobranej z osadnika Elektrowni "Skawina". Badania przeprowadzono w standardowym aparacie bezpośredniego ścinania. Analiza wyników badań pozwala stwierdzić, że mieszanina popiołowo-żużlowa charakteryzuje się dużymi wartościami parametrów wytrzymałościowych przy prawie niezmienionej wartości kąta tarcia wewnętrznego oraz znacznymi różnicami spójności pomiędzy przyjętymi kryteriami ścięcia.
The paper presents results of an investigation into the shear strength of the ash-slag mixture taken from the settling pond of the Power Plant "Skawina". The tests were carried out in a standard direct shear apparatus. The analysis of the test results shows, that the tested ash-slag mixture can be characterised by the big values of strength parameters at the almost unchanged value of the angle of internal friction and the significant differences of cohesion between the assumed shearing criteria.

Opis:
The goal of the paper was to present the selected socio-demographic features of Borne Sulinowo, a unique town in Poland, established within the area of the former secret military base of the Soviet Army and never used for non-military purposes before 1993. Borne Sulinowo is located in the north-west, approx. 20 kilometres from Szczecinek town. Before the World War II it had been a German garrison with the Wehrmacht Artillery School and after 1945 the area was taken over by the Soviet Army. The troops were present there until the end of 1992. Once the Soviet soldiers and officers have left the garrison, new Polish inhabitants started to come to Borne Sulinowo and develop the “new” town. That is why the socio-demographic structure of the town in its first 20 years (1993–2013) was peculiar, and so were the factors determining its transformation. The influence of the military past on the structure of Borne Sulinowo population has been shown in the paper. In 2013 the population of Borne Sulinowo consisted of approximately 4900 people; 60% of whom were between 18 and 59 years old. People under 18 made up 18% of the total population, whilst inhabitants over 60–22%. Because of the short Polish history of the town and the lack of traditions, Borne Sulinowo’s citizens are not fully integrated. Most of them came from different regions of Poland, thus having various backgrounds and cultures.

The novel mordent and disperse heterocyclic dyes were prepared by coupling of various diazo solution of aromatic amines with N-{4-[2-{3,5-bis(4-methoxyphenyl)-4,5-dihydro-pyrazol-1-yl}-2-oxoethoxy]phenyl}-1-(phenyldiazenyl)methanimine The resultant mordent and disperse heterocyclic dyes were characterized by elemental analyses, IR and NMR spectral studies. The UV-visible spectral data have also been discussed in terms of structural property relationship. All the disperse azo dyes were applied on polyester textile fibers. The percentage dye bath exhaustion and fixation on the polyester fibers have been found to be very good. Moderate to very good light fastness and washing fastness properties were indicated by the dyed fabrics. Structures of synthesized compounds were confirmed by physical and spectral analysis. The compounds are evaluated for their antimicrobial activities.

The model is built on the basis of knowledge bases. The authors focus on basic information required for maintenance department operation and expert archiving of technical documentation. Three main areas are covered by the model: knowledge acquisition and formalization, knowledge systematization and knowledge retrieval by problem or field. It is assumed that the implementation of the model coupled with an electronic knowledge acquisition report and with an application for information retrieval will bring benefits for the company.

Opis:
The modern method of analysis of the distributed parameter systems relies on the transformation of the dynamical model to an abstract differential equation on an appropriately chosen Banach or, if possible, Hilbert space. A linear dynamical model in the form of a first order abstract differential equation is considered to be well-posed if its right-hand side generates a strongly continuous semigroup. Similarly, a dynamical model in the form of a second order abstract differential equation is well-posed if its right-hand side generates a strongly continuous cosine family of operators. Unfortunately, the presence of a feedback leads to serious complications or even excludes a direct verification of assumptions of the Hille-Phillips-Yosida and/or the Sova-Fattorini Theorems. The class of operators which are similar to a normal discrete operator on a Hilbert space describes a wide variety of linear operators. In the papers [12, 13] two groups of similarity criteria for a given hybrid closed-loop system operator are given. The criteria of the first group are based on some perturbation results, and of the second, on the application of Shkalikov's theory of the Sturm-Liouville eigenproblems with a spectral parameter in the boundary conditions. In the present paper we continue those investigations showing certain advanced applications of the Shkalikov's theory. The results are illustrated by feedback control systems examples governed by wave and beam equations with increasing degree of complexity of the boundary conditions.
