Opis:
Stained-Glass – a Myth of Light and Color The art of stained-glass works has been related to the concept of sacrum for centuries. The genesis of this myth reaches the medieval era, when stained-glass had been one of the primary artistic techniques. The symbol- ism of light and color which has been known since the primeval times, an expression of God’s glo-ry, has perfectly inscribed itself in the program of ideological gothic cathedrals. For hundreds of years stained-glass has dominated church architecture, at the same time solidified the common conviction of its religious purpose. Only after cultural and social changes at the end of 19th century has traditional approach towards stained-glass been broken. It then entered widespread public and everyday space. In the next era, in 20th century, it became an expression of many independent artists. Due to their creative work, mythology of sacral stained-glass has expanded onto new areas. In modern times, stained-glass is a full-fledged art genre, free and in-depend- ent, but still dealing with deeply rooted conviction of the religious charac- ter of the glass masterpiec-es.

Opis:
Visible light communication (VLC) is a promising technology for wireless communication networks. Optical code division multiple access (OCDMA) is a strong candidate for VLC-based applications. The predominant source of bit error in OCDMA is the multiple access interference (MAI). To eliminate MAI in synchronous OCDMA, zero cross correlation (ZCC) codes have been proposed. However, synchronization problems and multipath propagation introduce relative non-zero time delays. Therefore, the zero correlation zone (ZCZ) concept was introduced. In this paper, we propose a new method for generating ZCC codes. The proposed construction can accommodate any number of users with flexible Hamming weight. The numerical results obtained show that the proposed codes significantly reduce MAI, compared to ZCC, as well as ZCZ codes.

Opis:
The main objective of this research is to examine the influencing parameters of driver performance through the yellow phase at urban signalized intersections with and without red-light running (RLR) cameras. Data were collected to include the intersection type, vehicle type, turning movement type, whether the vehicle position is in a platoon or not, presence of RLR cameras, green light flash devices, pedestrians, and pavement markings. A total of 2168 driver observations were extracted. Only 33.3% of the drivers stopped before the stop line, 59% of the drivers passed the intersection through the yellow phase, and 7% of the drivers committed RLR violations. The results showed that drivers were more likely to stop before the stop line through the yellow phase at locations with RLR cameras, green light flash devices, pavement markings, where pedestrians were present, and at a four-leg intersection. Chi-square tests indicated that all parameters had a significant impact on driver performance, except for the type of turning movement.

Opis:
Summary. This research is an attempt to compare engineering solutions for traffic intersections from a planning viewpoint. In this research, various solutions have been discussed for traffic intersections (traffic light, roundabout, underpass and overpass). The research highlighted the importance of each of these solutions in urban environments and clarified all variables related to the pros, cons, costs, capacity and environmental compatibility of each of these solutions with the surrounding urban environment. Weights were developed for all these variables, then correlation was determined using the linear regression method. The analysis of statistical results shows that the creation of underpasses often achieves most of the designated goals when compared to other solutions, despite some technical difficulties and high construction costs.

Opis:
In Czesław Miłosz’s poetry, light takes a special place. In my work, I have made an attempt to determine its role in the interwar poetry of the memberof the Żagary literary group, in which light takes various shapes which are often contrary to one another. One can look at them in search of not only a variability of artistic forms, but also for testimonies of the era and declarations of contemporary poetic worldview of the author of Three Winters (Trzy zimy). The clash with various interpretations of the word ‘catastrophism’ shows that light in Miłosz’s poetry leads far beyond the course of history.

Opis:
The review exposes basic concepts and manifestations of the singular and structured light fields. The presentation is based on deep intrinsic relations between the singularities and the rotational phenomena in light; it involves essentially the dynamical aspects of light fields and their interactions with matter. Due to their topological nature, the singularities of each separate parameter (phase, polarization, energy flow, etc.) form coherent interrelated systems (singular networks), and the meaningful interconnections between the different singular networks are analysed. The main features of singular-light structures are introduced via generic examples of the optical vortex and circular vortex beams. The review describes approaches for generation and diagnostics of different singular networks and underlines the role of singularities in formation of optical field structures. The mechanical action of structured light fields on material objects is discussed on the base of the spin-orbital (canonical) decomposition of electromagnetic momentum, expressing the special roles of the spin (polarization) and spatial degrees of freedom. Experimental demonstrations spectacularly characterize the topological nature and the immanent rotational features of the light-field singularities. The review is based on the results obtained by its authors with a special attention to relevant works of other researchers.

Opis:
Carboxymethyl cellulose (CMC) was used in the chemical reduction using sodium borohydride to yield dispersive nano zero-valent iron (nZVI) particles as reactive and stable adsorbents. CMC- -stabilized nZVI particles were characterized via UV-visible light spectroscopy, X-ray diffraction, dynamic light scattering, transmission electron microscopy, and specific surface area assisted using a probe ultrasonication dispersing tool at 50% amplitude power. High catalytic reactivity obtained in pseudo-first order reaction for Cr6+ (rate constant K1 = 0.0311 min–1) and pseudo-second order for Cu2+ (rate constant K2 = 0.0946 g·mg–1·min–1) indicated that colloidal stability of nZVI particles can be achieved with a stabilizer for the removal of toxic contaminants.

Opis:
A comparison of methods for obtaining nanocellulose using acid and ionic liquid hydrolysis reactions. In this study, two methods were compared, i.e. acid hydrolysis using sulphuric acid (VI) and ionic liquid hydrolysis using 1-methyl-3-butylimidazolium chloride to obtain nanocellulose from Sigmacell Cellulose Type 20. The efficiency of both processes was tested for weight loss of the material during the reaction. The study showed that much more material can be obtained using ionic liquid hydrolysis than using acid hydrolysis. A dynamic light scattering study was performed to determine material particle size before and after these processes. Particles of nanometric size were recorded only for cellulose after the reaction with an ionic liquid. In addition, Fourier transform infrared spectroscopy was performed to determine the chemical structure of the materials tested.

Artykuł opisuje znaczenie symbolu światła w paschalnej liturgii Jerozolimy pierwszego tysiąclecia chrześcijaństwa. Obrzęd zapalenia światła na początku liturgii Wigilii Wielkanocnej (zwany paschalnym Lucernarium) jest obecny we wszystkich źródłach liturgicznych liturgii jerozolimskiej. Najbardziej znaczące z nich to: Itinerarium Egerii (z końca IV w.), lekcjonarz ormiański (V w.), Wielki Lekcjonarz Kościoła jerozolimskiego tradycji gruzińskiej (VI-VIII w.) oraz Typikon kościoła Anastasis (XII w.). Rozwój obrzędu wielkanocnej liturgii światła, obejmujący zapalenie świecy lub kilku świec wewnątrz edykułu Bożego Grobu, przekazanie światła wszystkim wiernym, modlitwy, śpiew psalmów i antyfon oraz procesje, podkreśla, iż celebracja tajemnicy zmartwychwstania Chrystusa w Jerozolimie miała zawsze wymiar chrystologiczny i eklezjologiczny.
This article examines the relevance and the significance of the symbol of the light in the paschal liturgy in Jerusalem in the first millennium. The rite of the lighting the candle, which opens the liturgy of the Easter Vigil (called the Easter Lucernarium), is present in all the known sources of the Jerusalem liturgy. The most significant of these are Itinerarium Egeriae (end of the 4th century), the Armenian Lectionary (5th century), the Grand Lectionary of the Church of Jerusalem from the Georgian tradition (6th-8th century) and the Typicon of the Anastasis (12th century). The development of the rite of paschal light – which includes the lighting of the candle or candles inside of the chapel of the Tomb of Christ, passing the fire to the whole congregation, prayers, psalms, antiphons and processions – reflects the profound theological significance of the Resurrection of Christ. Indeed, the celebration of Easter in Jerusalem, thanks to the very evocative symbol of light, has always been preeminent among Christological and ecclesiological event.

Studies on the structure of a 140 to160−year−old Fagus sylvatica stand at Chorzów, Upper Silesia were undertaken. The single−layer stand had a dense canopy and was in good health. Limited natural regeneration occurred. There were numerous seedlings reaching 0.5 m in height growing in well−lit places. However, the rate of seedling occurrence was low under the dense canopy, indicating that insufficient light is the main factor affecting the degree of regeneration.

Opis:
In this paper, self-phase modulation of an optical pulse using a new photonic crystal coupled-cavity waveguide is simulated and analyzed. The structure of the new coupled-cavity waveguide is introduced and its advantage over the previous type of coupled-cavity waveguide is discussed. In order to obtain a high group index over a large bandwidth and benefit from the slow light phenomenon, the group index and group velocity dispersion parameter curves of the guided mode are calculated. Finally, the transient simulation of the structure is performed using a finite-difference time-domain method. The calculated required length of the coupled-cavity waveguide for a maximum phase shift of π is about 31 μm. Spectral broadening of the optical pulse as a result of self-phase modulation is also presented and discussed.
