This article discusses the last Sunday in the Pre-Lenten period in the liturgical tradition of the Orthodox Church known as “Cheese-fare Sunday” or “Forgiveness Sunday”. The faithful’s attention is concentrated on the need to forgive others as one of the main conditions of crossing the threshold of Great Lent. Particularly noteworthy is the explanation of the very term “forgiveness”, as well as the kind of theological and moral message that the Fathers of the Church and the authors of the texts of the services of Great Lent find in it. Furthermore, it also clearly points out the tragic consequences of the fall of man, which is why has also been called “The Sunday of the Expulsion of Adam and Eve from Paradise.” The main reason for recollecting this tragic event is the purely didactic aspect. There are two perspectives of spiritual life for a man who begins the trial of a fast way. On the one hand, endowed with free will - like the protoplasts - has the opportunity to choose a life in accordance with God’s commandments, which will result in constant communion with Him and saturating the gift of His grace. On the other hand, he observes what the lack of temperance and disobedience to the Creator causes. Great Lent is therefore an attempt to show the right way to return to Paradise reality and unity with God and people.

Heresy is usually defned as an error concerning the content of faith. In this article heresy is shown as a sin requiring conversion and penance and not just a withdrawal of one’s views. A sin of heresy is compared to adultery or idolatry, for which the same penance used to be assigned (e.g. Synod of Elvira in 306, can. 22). In this context the condemnation of Nestorius by the Council of Ephesus in 431 is characteristic because it is focused on the insult to Jesus Christ and not on erroneous conceptions. It is also the case with the formulas of condemnation of heretics where such invectives as contamination, sacrilegium or perfdia were often used, and those terms belong to the feld of morality rather than to intellectual disputes or differences.

The present paper aims at analyzing the conceptual metaphors for sin identifi ed in the English version of the Bible. The experience of moral evil belongs to basic human experiences and in theological interpretation, its existence is the reason for the salvation brought to people by Christ. However, from the semantic point of view, the concept of sin itself is highly abstract and diffi cult to defi ne. In order to conceptualize that notion, people frequently employ conceptual metaphors which enable them to refer to the abstract through the use of the concrete. This study is based on the English translation of Scripture published as the New Revised Standard Version, Catholic Edition (2007[1989]). That version of Scripture is a revised edition of the famous King James Bible (1611) and it is widely used among Christians representing various denominations. The identifi ed sin metaphors are based on either sensorimotor or cultural experience. There are conceptualizations of sin that are motivated by preconceptual image schemas, ontological metaphors, and metaphors that combine cultural scripts and image schemas.

The analysis of web-corrugated and trapezoidal profiled web girders focuses on the description of buckling resistance, possibly the ultimate resistance neglecting the post-buckling resistance reserve of girders. The problem is still the post-buckling resistance reserve and its possible application in practice. For this purpose this paper presents the analysis of tests on shear resistance of the corrugated web of SIN girders with the support stiffeners in the pre- and post-buckling zones. There are also presented values of the post-buckling resistance zone and the mutual relationships between pre- and post-buckling resistance zones. Values of these zones are related to optimization of the web-corrugated girders, which consists in enlarging the zone of pre-critical resistance and balancing between shear resistance and bending resistance. The experimental tests were performed on 20 girders with the following web depth: 500, 1000, 1250, and 1500 mm, composed of three pre-assembled units. The girders with a simply supported beam system and a simply supported beam with a single cantilever were made of pre-assembled units joined by means of high strength preloaded bolts. The numerical analysis by FEM was conducted for the models with web depth from h_w = 500 to 1500 mm at the full range of web thickness 2,0; 2,5, and 3 mm. The tests showed that stiffness of the support stiffeners in the web-corrugated girders had an impact on the size of pre- and post-buckling resistance zones, which consequently reduced the zone of post-buckling resistance. Because the initiated loss of stability of the corrugated-web girders is an irreversible and rapid process, and the resulting displacements in the non-linear area are permanent, the application of the post-buckling resistance zone in practice can be troublesome. From the standpoint of the structural reliability, however, the post-buckling zone provides a yield delay, i.e. it may be regarded as a safety margin. Therefore, its most possible reduction is required.

The aim of the paper is the residual stress analysis of AlSi10Mg material fabricated by selective laser melting (SLM). The SLM technique allows to product of complex geometries based on three-dimensional model, in which stiffness and porosity can be precisely designed for specific uses. As the studied material, there were chosen solid samples built in two different directions: parallel (P-L) and perpendicular (P-R) to the tested surface and cellular lattice built in perpendicular direction, as well. In the paper, for the complex characterization of obtained materials, the phase analysis, residual stress and texture studies were performed. The classical non-destructive sin2ψ method was used to measure the residual stress measurements.

The final products, both solid sample and cellular lattice, have a homogeneous phase composition and consist of solid solution Al(Si) (Fm-3m) type, Si (Fd-3m) and Mg2Si (Pnma). The obtained values of the crystallite size are in a range of 1000 Å for Al(Si), 130-180 Å for Si phase. For Mg2Si phase, the crystallite sizes depend on sintering process, they are 800 Å for solid samples and 107 Å for cellular lattice. The residual stress results have the compressive character and they are in a range from –5 to –15 MPa.
