z różnych dziedzin nauki i techniki, takich jak: biologia roślin i zwierząt, technika
świetlna, astronomia, nauki prawne, astroturystyka, architektura i urbanistyka. Cechą
charakterystyczną monografii jest szerokie, interdyscyplinarne spojrzenie na oddziaływanie
sztucznego światła na otoczenie. Cenną pomocą, którą zamieszczono
w monografii, jest także poruszenie zagadnienia pomiarów zanieczyszczenia

Functional properties of nonwovens as an insulating layer for protective gloves
No full textThe basic aim of research presented here is to analyse the influence of the incorporated microporous
membrane and the technology of needling process on the functional properties of nonwovens developed
as an insulating layer for protective gloves. The studied nonwovens are produced with carded web
formation and mechanically bonded with needle bonding. The nonwovens studied contain a
microporous membrane of PES with a thickness of 20 μm (samples ST and STL). The experimental part
of the present work deals with the mechanical properties: Breaking stress and elongation as well as
elastic recovery after cyclic loading. The permeability properties (air permeability) and thermal
conduction are also analysed in the experimental part. Research results show that the samples ST and
STL, which contain a microporous PES membrane, have a higher breaking stress than the samples T
and TL without the microporous PES membrane. Samples ST and STL also show higher values of
breaking elongation than samples T and TL. Samples ST and STL are mechanically bonded to the
lamella plate using forked needles and therefore have a structured (ribbed) shape that affects the
improved mechanical properties. The TL and STL samples, which contain a microporous PES
membrane, have higher elastic recovery and lower air permeability than the T and TL samples
Solvent-based recycling of polypropylene from waste carpets: an investigation on the leaching behaviour of carpet components
No full textPolyolefins, mainly polyethylenes (HDPE or LDPE) and polypropylene (PP) are major types of
thermoplastics used in a wide variety of applications throughout the world. Polypropylene is used in a
wide variety of products, ranging from packaging materials to textile products like carpets, and one of
the major contributors to environmental pollution, which calls for the development of effective and
efficient recycling methods. The aim of this study was to investigate the leaching behavior of waste
carpets’ components in the proprietary solvent designed for selective dissolution of PP in order to
determine the pre-processes required to obtain PP-rich feedstock material and high purity recycled PP
polymer
Telemedicine as a Breakthrough for the Healthcare System
No full textTelemedicine is one of the answers to the growing need for the different kinds
of medical services which one can see in society nowadays. The technological
progress observed recently is a precursor of the development of telemedicine.
The possibilities offered by telemedicine are advantageous for both the patient
and the healthcare provider, and one of the main benefits is access to
distance healthcare.
This means medical care without the need for an in-clinic appointment or for
patients or medical professionals to travel to the place of treatment. Recently,
when we struggled with a pandemic and limited the amount of interpersonal
contact. Therefore, the solutions brought by telemedicine appear to provide an
effective and safe alternative to a significant part of in-clinic appointments.
In Poland, however, there are still some barriers to disseminating these solutions,
including limited technical possibilities, insufficiently defined effectiveness
and financial efficiency and limited acceptance by the payer. This article presents
the services and possibilities offered by telemedicine, its advantages
and disadvantages from the doctors’ perspective and analyses its legal aspect

Development of the alps observing network
No full textPrzedstawiamy rozwój, działanie i cele projektu ALPS. Projekt
skupiony jest na monitorowaniu poziomu zanieczyszczenia światłem na
terenie Polski, a w szczególności w obserwatoriach astronomicznych. W tym
celu gromadzone są dane numeryczne w postaci jasności powierzchniowej
nieba mierzonej w okolicach zenitu oraz wykonywane są obrazy całego nieba.
Dzięki tak prowadzonym pomiarom możliwa jest ilościowa ocena stopnia
degradacji nocnego nieba przez światło antropogeniczne. Powoduje ono
wzrost jasności nieba, a przez to spadek jakości obserwacji, czyli badań
naukowych w dziedzinie astronomii. Kontrola i ograniczanie zanieczyszczenia
światłem jest więc koniecznością z punktu widzenia astronomii. Sieć stacji
obserwacyjnych ALPS jest elementem, który może wesprzeć te działania.We present the development, operation and goals of the ALPS
project. The project focuses on monitoring the level of light pollution in Poland,
in particular in astronomical observatories. For this purpose, numerical data
are collected in the form of the surface brightness of the sky, measured near
the zenith, and images of the entire sky are also made. Thanks to such
measurements, it is possible to quantify the degree of degradation of the night
sky by anthropogenic light. This light causes an increase in the brightness of
the sky, and thus a decrease in the quality of observations, i.e. scientific
research in the field of astronomy. Controlling and reducing light pollution is
therefore a must from an astronomy point of view. The ALPS network of
observation stations is an element that can support these efforts
From Red to Turquoise – Reflections on Organizational Culture and Young Generations
No full textOrganisational culture issues evolve along with the transformation of the labor
market. It is also important to popularise the idea of turquoise organizations,
which is of interest to an increasing number of management theorists and
practitioners. An important issue for organizational culture is the professional
functioning of the new generations – the „Zˮ generation, which is already
present on the labor market, and the „Alphaˮ generation, which will enter
adulthood in a few years. This article attempts to characterise synthetically
various types of organizations. Based on the analysis of existing data, a list of
expectations and challenges for young employees and employers is provided
