ABSTRAKT Łaskami słynący obraz Matki Boskiej Miłosierdzia Kazimierzowskiej w Rajczy (64 x 45,8 cm), malowany jest w technice olejnej na ręcznie kutej blasze miedzianej. Niezachowaną, pierwotnie hebanową ramę z podpórką, pozwalającą umieszczać dzieło na domowym ołtarzyku, zastąpiła nowa, profilowana i złocona rama. Obraz znajduje się w głównym ołtarzu kościoła parafialnego pw. Św. Wawrzyńca, diakona i męczennika i św. Kazimierza, królewicza w Rajczy. 1 VII 2017 wizerunek został ukoronowany koroną biskupią. Obraz o najwyższej klasie artystycznej, stanowi najlepszą znaną obecnie kopię cudownego obrazu Matki Boskiej Częstochowskiej jaka powstała w drugiej ćwierci XVII w. Wizerunek namalowano bezpośrednio z oryginału, za czym przemawiają jego cechy formalne, m.in. z precyzyjnym uwzględnieniem tzw. koron władysławowskich, jakie w latach1625-1633 ufundowano dla ozdoby jasnogórskiego oryginału. Kopia najprawdopodobniej powstała w malarni jasnogórskiej, a jej autorem być może był paulin o. Jan Felicjan Ratyński. Obraz, co potwierdzają źródła historyczne, podarował do mającego się zbudować w Rajczy nowego kościoła król Jan II Kazimierz Waza (1609-1672), właściciel dóbr żywieckich. Stało się to po jego abdykacji w drodze do Francji w Żywcu 4 lipca 1669 r. Od 1684 r. wizerunek jest przechowywany w Rajczy – najpierw w drewnianym kościele, a po jego rozbiórce wobecnym nowym. Pomiędzy majem 2016, a lutym 2017 roku przeprowadzono specjalistyczną konserwację oraz badania fizyczno-chemiczne podobrazia, co zwiększyło naszą wiedzę o obrazie. Cudowny wizerunek Matki Boskiej Kazimierzowskiej poprzez swój związek z królem Janem Kazimierzem, będąc również kopią jednego z najbardziej rozpoznawalnych polskich obrazów maryjnych, zajmuje w polskiej sztuce miejsce wyjątkowe. Jego wartość artystyczno-historyczna idzie w parze wraz z wartością kultową, stanowiąc ważny punkt odniesienia dlachrześcijańskiej pobożności. SUMMARY A miraculous painting of Our Lady of Mercy of Kazimierz in Rajcza (64 x 45.8 cm) was painted in oil technique on handforged copper sheet. Unpreserved, originally an ebon frame with a support, allowing to place the masterpiece on a home altar, was replaced with a new, profiled, gilded frame. The painting is placed in the main altar of the parish church of St. Lawrence, a deacon and martyr and St. Casimir in Rajcza. On July 1, 2017 the painting was crowned with an episcopal crown. The painting recognized as of the highest artistic class is the best-known copy of a miraculous painting of Our Lady of Częstochowa that originates from the second quarter of the 17th century. There are some features such as precise mapping of the so-called crowns of Władysław IV, founded to adorn the original painting from Jasna Góra Monastery, that make scientists believe that while making the painting for the King, the artist was directly looking at the original painting of Our Lady of Częstochowa. The copy was most likely created in the Jasna Góra painting house, and its author may be a Pauline Father, JanFelicjan Ratyński. It is confirmed by historical sources that King John II Casimir Vasa (1609–1672), the owner of Żywiec estates, gave the painting to a new, soon-to-be built church in Rajcza. The King did it after his abdication, on July 4, 1669, in Żywiec when he was on the way to France. Since 1684 the painting has been placed in Rajcza, first in the wooden church, and after its removal, in a current one. Between May 2016 and February 2017 specialized conservation as well as physical and chemical tests of canvass stretcher were carried out to update the knowledge about the painting. Through its relations with King John II Casimir Vasa and the fact that it is the copy of one of the most recognizable Polish Marian paintings, the miraculous painting of Our Lady of Mercy of Kazimierz holds a unique place in Polish art. Its artistic and historical value goes hand in hand with a cultural value, constituting an important point of reference for Christian piety.

Metal nanoparticles have been deeply studied in the last few decades due to their attractive physical and chemical properties, finding a wide range of applications in several fields. Among them, well-defined nano-structures can combine the main advantages of heterogeneous and homogenous catalysts. Especially, catalyzed multi-step processes for the production of added-value chemicals represent straightforward synthetic methodologies, including tandem and sequential reactions that avoid the purification of intermediate compounds. In particular, palladium- and copper-based nanocatalysts are often applied, becoming a current strategy in the sustainable synthesis of fine chemicals. The rational tailoring of nanosized materials involving both those immobilized on solid supports and liquid phases and their applications in organic synthesis are herein reviewed.

Since the 1960s, the artistic and architectural interventions carried out in the church of Santa Isabel and Rato Chapel, in Lisbon, brought to the debate the overlap of different narratives in these two different spaces of worship: the first, is a parish church preserved by the earthquake of Lisbon (1755), which had its liturgical space redesigned before the Second Vatican Council; the second, is a private chapel annexed to a 18th century palace that became a symbolic worship space for students and engaged young professionals since the 1970s. Enriched with the work of either well-known artists or, sometimes, anonymous architects, the two case studies show us the life of monuments, where Modern and Contemporary Art and Architecture participate in preserving and enhancing their cultural value. At the same time, the liturgical and pastoral activities are shown to be the engine behind successive interventions.

In this work, a method to measuring the magnitude of a uniform magnetic field in space using current balance was described. A simple experimental set was designed and constructed using low-cost materials. This constructed current balance consists of copper sheet, weight pan, and acrylic sheet. A copper sheet was cut into a U-shape and attached at the end of acrylic balance arm. A weight pan was hanged in the opposite side of the balance arm with high sensitivity to a small torque. The horizontal segment of the U-shaped copper sheet, which the length l was 3 cm, was located inside the influence of an uniform magnetic field produced by two parallel bar magnets with opposite poles facing each other. The magnetic field direction was perpendicular to the horizontal segment. When a current was supplied to the copper sheet, the magnetic force acting on a horizontal segment of length l carrying a current I in a magnetic field B was given by. In the experiment, the current was varied from 0 1 A. For each value of applied current, the magnetic force on a thin straight sheet of length l was measured by adding masses to the pan until the balance arm moved to the equilibrium between opposing gravitational and magnetic forces. The results showed that the magnetic force increased linearly with increasing applied current. By plotting a linear graph of magnetic force versus applied current, the magnetic field B can be calculated from . The calculated and actual values of B were 100.32 and 100.13 mT, respectively. This constructed current balance is an excellent tool for high school and undergraduate fundamental physics courses. Students will be excited when they see the balance arm rising or going down due to magnitude and direction of current flowing in a conductor wire.

Concentrating on the series “Girls” (2012–2017), “Fleabag” (2016), and “Insecure” (2016–), this article examines the female-centered dramedy as a current genre of U.S.-American television culture with specific investments in gendered value hierarchies. The article explores the format’s dominant narrative and aesthetic practices with specific focus on prestige dramedy’s “cringe” aesthetics. Cringe is increasingly mobilized as a mode of political expression following the format’s privileging of female subjectivities. As such, cringe is tasked with negotiating the tensions between drama and comedy on one hand and intersectional relations of identity politics on the other. Character “complexity,” embedded in ideological themes around identity, modifies the “comedy” in cringe and becomes associated with the more prestigious dramatic mode, this way governing the texts’ appeal to cultural value. The article demonstrates the ways the female-centered cringe dramedy expresses its politicization and “complexity” via disturbing gendered expectations of mediated femininity, and specifically body and sexuality politics.

The purpose of this study was to evaluate the two techniques that are commercially used to bond the components of composite electrical contacts. These materials, usually consisting of a precious metal contacting region bonded to a copper substrate, offer substantial economy compared to similar devices made entirely from precious metals. They also possess unique desirable properties useful in other electronic and biomedical applications. However, these advantages can only be realized if the weld can withstand the severe physical and chemical environment in which it must operate.The resistive welds are created by bringing the components into contact and then providing a current in order to create sufficient heat for welding. Induced-arc welding requires more operations: the components are held apart with a relative potential of 10 to 100 volts; then they come into contact very briefly, 50 to 500 μsec; they are immediately drawn apart, striking an arc; finally, after arcing from 300 to 3000 μsec, they are forced together percussively while the current continues to flow.

Maintenance and restoration of historical buildings are an important contribution to sustainability of cultural heritage. Refurbishment should be adopted to preserve the essential features of the building ́s history and cultural heritage. Reconstruction of internal plaster in historical buildings belongs to important treatment in a landmark area. Plaster of historical buildings is usually characterized by an open porosity, which makes it sensitive to the degradation caused by physical and chemical agents. Alterations and structural faults can lead to invasive interventions which modify permanently the cultural value and the structural behavior of the buildings, in conflict with necessary preservation requirements.Knowledge of the historical building interior microclimate is essential for the definition of suitable reconstruction. Computer simulation plays major role in determining air flow, which can cause negative influence within historic buildings such as high level of moisture, fungus, chemical reactions etc. In order to prevent deterioration of plaster and to retard their decay, protective products – nanofibers – could be applied on the historical surfaces. Using nanofibers should cause minimal modifications to the historic appearance and protect from negative influences.

The Electrician of 27 June 1890 reported, that ‘the Thomson alternate current motor which attracted so much attention at the Royal Society soirée last week was actuated by a current generated by the Ferranti alternator at Deptford’. This simple statement recorded the first practical realization by a 26-year-old engineer of his vision of central electricity generation. He conceived of generating stations at locations where land was cheap, where water was abundantly available, and where sea-borne coal could readily be delivered, with efficient transmission of the electricity at high voltage to centres of actual consumption. This idea, which is so familiar to us today, was at that time strange and untried and subject to powerful opposition, but the energy and enthusiasm of this young man overcame all obstacles to its success. Sebastian Ziani de Ferranti was born in Liverpool on 9 April 1864 in a house at 130 Bold Street, near St Luke’s Parish Church. He was a direct descendant of the Doge Sebastiano Ziani, one of the hero princes of Merchant Venice, through a branch of the family which settled in Bologna and added ‘de Ferranti’ to the name in the eighteenth century. Sebastian’s father came to England in 1859 and set up a photographic studio in Liverpool, which was patronized by many distinguished people of the time. His mother, Juliana, daughter of the portrait painter William Scott and Sarah Myers of Poughkeepsie, New York, was a talented musician, who had given piano recitals in most of the capitals of Europe.
