ANALIZA STOSOWALNOŚCI USŁUG SIECIOWYCH TYPU REST I SOAP
Web Services are common means to exchange data and information over the network. Web Services make themselves available over the Internet, where technology and platform are independent. These web services can be developed on the basis of two interaction styles such as Simple Object Access Protocol (SOAP) and Representational State Transfer Protocol (REST). In this study, a comparison of REST and SOAP web services is presented in terms of their applicability in diverse areas. It is concluded that in the past both technologies were equally popular, but during the rapid Internet development the REST technology has become the leading one in the area of access to Internet services.Usługi sieciowe są powszechnie stosowane do wymiany danych i informacji w Internecie. Usługi sieciowe nie zależą od użytej platformy sprzętowej oraz od oprogramowania. W niniejszym artykule zostały omówione dwie najpopularniejsze technologie tworzenia usług sieciowych: REST (ang. Representational State Transfer) i SOAP (ang. Simple Object Access Protocol). W trakcie realizacji badań przeprowadzono analizę stosowalności tych usług w różnych obszarach zastosowań. Stwierdzono że w przeszłości obie technologie cieszyły się porównywalną popularnością, lecz w momencie gwałtownego rozwoju Internetu technologia REST stała się technologią dominującą w zakresie dostępu do usług sieciowych
Fourth generation of fermions and the magnetic moment of the neutrino
There exist many various speculations on the magnetic moments of the neutrinos [1].
In the light of the recent papers [2] a big magnetic moment of the neutrino can explain
the solar neutrino flux puzzle. In any case, whether it is true [2] or not [3] it is worth to
investigate, what is the limit of the magnetic moment of the neutrino within the Glashow-
-Salam-Weinberg (GSW) model[…
Electromagnetic structure of the massive, Dirac neutrinos
All the electromagnetic formfactors for the massive, Dirac neutrinos are calculated
in the frame o f the GSW model. Their dependence on the Kobayashi-Maskawa mixing
and C, P, T properties are discussed. Three formfactors depend on gauge, the other ones are
gauge independent. In the static limit q2 -* 0, in one loop approximation the Dirac neutrino
has two electromagnetic characteristics— the magnetic moment (which vanishes for massless
neutrino) and anapole (which is different from zero in the massless limit). Present experimental
data do not give possibility to check these static properties o f the neutrinos[…
Radiative Corrections to the Neutrino Counting Process e+e−→ννγ
The standard model weak corrections to the process e+e- -» vvy which are important
from the point o f view o f consistent renormalization are calculated. The calculations o f the
hard bremsstrahlung corrections to the process are done and they are found to be in good
agreement with the former results
The normal product in quantum theory
The aim o f this paper is purely technical. We want to show the positive points and
shortcomings in practical application o f the two procedures in quantum field theory. The
first — the canonical quantization approach which uses the normal product (NP) and the
second procedure, the Feynman path integral approach without the normal product (WNP).
To compare both procedures we have made detailed renormalization o f the <f* theory and
o f the scalar electrodynamics[…

Gendered perceptions and socio-economic and spatial determinants of fear of crime: an empirical analysis in Szczecin, Poland
The study of the fear of crime phenomenon provides a socially and politically important research question. Many studies show that gender differentiates the fear of crime, which is why we examine this phenomenon in a spatial perspective. The female versus male perspective of feelings of safety in residential areas were significantly different. The research was carried out using the CAWI technique in the city of Szczecin, in Poland (n=346). The research also examined which factors influenced the fear of crime the most: darkness, socio-economic characteristics, type of violations, number of registered crimes, or the assessment of police work. The research shows that women aged 19–25 are the group that reports the highest fear of crime. They are generally better educated, work or study, but often come from peripheral rural areas, and their current place of residence is little known. Activities aimed at building a sense of security in local communities should therefore be addressed to a wide demographic spectrum of recipients, but with emphasis on young females. A very interesting result from the research is the relationship between fear of crime and the opinion of residents about the effectiveness of police work, where the study reports that the better the assessment of police work, the lower the fear of crime
Prospective catalytic structured converters for of from biogas stationary engines : in situ template-free synthesis of ZSM-5 Cu exchanged catalysts on steel carriers
The main objective of this study is to develop
highly active catalyst and its preparation method that
would meet the requirements of steel carriers for short-
channel structured converters for NO
x
abatement from
stationary biogas engines. The in situ synthesis was applied
to deposit a series of Cu-exchanged MFI zeolite (ZSM-5)
on kanthal sheets. The samples differ in preparation con-
ditions: organic template assisted and template-free syn-
thesis, Si/Al ratio and catalyst carrier pretreatment
(calcined vs. non-calcined). Dip-coating method was used
as a reference to compare loading efficiency. In order to
evaluate preparation quality and purity of resulting struc-
ture the samples were examined by XRD and SEM/EDS at
various stages of preparation. For the assessment of
mechanical endurance of the deposited catalyst layers the
ultrasonication method was used. The results demonstrated
high depositing efficiency of the in situ synthesis as well as
high activity and selectivity of the Cu-exchanged MFI
samples prepared without costly organic template
The morphological conditions of the permanent pacemaker lead extraction
Pacemaker lead extraction is the treatment of choice in infectious complications regarding implantation procedure. The purpose of this study was to estimate the safety of the extraction in relation to the morphological changes of the pacing electrode. Research was carried out on materials consisting of 60 human hearts from 45 to 95 years of age (average 63 ± 15 yrs), with VVI or DDD pacing (pacing duration 84 ± 26 months) fixed in a formalin solution. Classical macroscopic anatomical methods were applied.
In 44 hearts (73.3%) from the investigated group the posterior tricuspid leaflet was thickened only, and in 24 of these hearts the process regarded not only posterior leaflet but also the septal one and especially commissure between them. In 52 hearts (86.6%) inflammatory reaction spread also to the neighboring part of the electrode. The length of the neointima-inflammatory tissue ranged from 4 to 8 mm (average 5 ± 2 mm). On the tip of the electrode in the right ventricle cavity in 56 hearts (93.3%) we observed that endocardial leads were surrounded by fibrous thickening , and partially covered by endocardial tissue.
We concluded that from the anatomical point of view the extraction of the pacing electrode seems to be questionable, especially in long-term permanent pacing. The experimental traction shows that only recently implanted electrodes were removed without any complications and in others with fraction of the tip, myocardial tissue avulsion or such removal was not successful at all
