Opis:: This study investigates the impact of renewable (REW) and non-renewable (NREW) energy usage, along with economic growth (GDP), on carbon dioxide (CO2) emissions in the Visegrad countries, which rely heavily on traditional energy sources. Using data from 1991 to 2021, the analysis employs a panel asymmetric regression with Driscoll-Kraay and FGLS standard errors. The latent cointegration test reveals long-term relationships with asymmetry among the variables. Real GDP fluctuations exhibit a negative impact on CO2emissions for both positive and negative shocks. A reduction in conventional energy source consumption leads to a greater CO2 emission reduction, confirming asymmetry. Conversely, an increase in consumption positively impacts CO2 reduction. However, non-conventional energy sources show no asymmetries. The OLS-based model proposed by Driscoll-Kraay showed reduced standard errors, but lower significance in the estimated parameters compared to the FGLS model. The findings recommend a sustainable energy transition for Visegrad countries by eliminating traditional sources and promoting renewable resources.

Opis:: New organizational and technical solutions aimed at optimizing the Polish Armed Forces Logistic System (PAFLS) and national task contingents are due to modern conditions under which military operations, mainly of expeditionary character, are conducted in the allied and international environment. The PAFLS and the Polish Military Contingent's organizational and technical structure is still (notwithstanding the numerous efforts that were made) the vast optimizing space which can be filled when the possibilities created by civil logistics experience are taken into account.

Opis:: In order to describe the environment surrounding us, so complex in terms of relations resulting from using violence, we easily employ terms such as ‘partisan’ or ‘militant’, just in order to define the very same ones as terrorists a while later. Probably the benchmark of contemporary description, especially of political action is the lack of clear-cut attitudes. Terrorism is nothing new, and this statement in itself is not very revealing. However, for many contemporary researchers of this issue, there is never too much information. Terrorism has always accompanied the history of oppressive regimes as well as resistance movements and uprisings. All the same, within the anti- colonial insurrectionary movements of the mid-20th century which led to the fall of European colonial empires over a short period of time, terrorism achieved new quality. It should also be emphasized that it achieved considerable political successes compared to the social-revolutionary terrorism of the late 19th century. The attribute ‘terrorist’ serves as an excluding one in different relations. By employing such term, one that their cause is an unconventional one – leastways as long as specific ways of using violence are applied. On the other hand, groups classified as terrorist ones often describe themselves as partisans who are fighting for the liberation of certain social or ethnic groups and who have to employ “unconventional” methods of using force because of the military superiority of the oppressive regime. By describing certain actions as ‘terrorist’ one usually intends on bereaving it of every sort of political legitimation. Is there any aspect that terrorism and guerrilla actions have in common? In certain socio-revolutionary or ethno-separatist strategies of violence, the concept of terrorism consists in the idea of a ‘starter’ which is to create the conditions to commence the guerrilla war. There could also be groups acting as partisans on one front line, and as terrorists on the other. The example is Al-Qaeda: in Central Asia its network operated only temporarily, as a kind of guerrilla, while in the global scale it employed terrorist strategy.

Opis:: This study recruited 14 young male participants to examine human 4-h maximum acceptable weight of lifting (MAWL) and maximum weight of lifting (MWL) for different modes of asymmetric lifting and containers. The results showed that asymmetric lifting with trunk rotation decreased MAWL and MWL by 9.1 and 17.3%, respectively, and asymmetric lifting with body turn decreased MAWL and MWL by 6.1%, when compared with the symmetric lifting. The decreasing effects of container width and MAWL and MWL were greater than those of container length. Participants selected MAWL of ~33–37% of their MWL capability.

Opis:: The paper presents research results on the selection of parameters for the asymmetric rolling process of bimetallic plates 10CrMo9-10+X2CrNiMo17-12-2. They consisted in determining the optimum parameters of the process, which would be ensured to obtain straight bands. Such deformation method introduces in the band the deformations resulting from shear stress, which affect changes in the microstructure. But their effect on the structure is more complicated than in the case of homogeneous materials. It has been shown that the introduction of asymmetric conditions into the rolling process results in greater grain refinement in the so-called hard layer. There was no negative effect on the structural changes in the soft layer observed.

Opis:: The 2019 PBC document views relationships between parents and children, masters and servants, “shepherds” and “the flock,” civil authority and citizens as asymmetric. The structure of the document suggests that these relationship systems are based on shared human experience and a common theological foundation: they appear to repeat the pattern of the parent-child relationship and originate in the obligation to obey God. Using the document as a starting point, I would like to outline what the concept of asymmetric relationships can mean today. In search of common perspectives, I will compare New Testament texts with the interpretation of asymmetry in today’s social ethics discourse. The inequality and asymmetry of different persons and groups seem to be an undeniable fact, causing tension that can be resolved fruitfully by parties who take responsibility for each other in the presence of a “third.”

Opis:: W pracy przedstawiono wybrane metody bootstrapowe estymacji przedziałowej wartości oczekiwanej populacji o rozkładzie asymetrycznym. Rozważano standardową metodę bootstrapowa, metodę percentyli oraz metodę t-bootstrapową. Metody te można stosować przy estymacji wartości oczekiwanej zmiennej losowej o rozkładzie asymetrycznym, zarówno dla małych jak i dużych prób. Analiza własności bootstrapowych metod estymacji przedziałowej przeprowadzona została metodami Monte Carlo.
In the paper we present some chosen bootstrap methods of interval estimation of the population expectation for asymmetric distribution. We consider the standard bootstrap method, percentile method and t-bootstrap method. These methods can be used to estimate the expected value of asymmetric distribution for, both, small and large sample sizes. The analysis of the properties of bootstrap methods of interval estimation is performed by means of a simulation experiment.

Opis:: Based on Chebyshov polynomials, one can create an asymmetric cryptosystem that allows for secure communication. Such a cryptosystem is based on the fact that these polynomials form a semi-group due to the composition operation. This article presents two new cryptosystems based on modifications of Chebyshev's polynomials. The presented analysis shows that their security is the same as in the case of algorithms associated with the problem of discrete logarithms. The article also shows methods that allow for the faster calculation of Chebyshev polynomials.

Opis:: Over the last 20 years asymmetric aminocatalysis has emerged as highly useful and reliable method of asymmetric synthesis. It involves the use of primary or secondary amines as catalysts of various stereoselective transformations of carbonyl substrates. Owing to the diverse activation strategies available in asymmetric aminocatalysis, it became a method of choice when the functionalization of prochiral aldehydes and ketones is considered. As a consequence, a direct and straightforward access to various chiral building blocks is possible that is of relevance to modern stereocontrolled organic synthesis. In the manuscript, the development of various aminocatalytic activation concepts is described and recent, selected contributions to this field of chemistry discussed. Main advantages of these strategies are highlighted providing an overview of this fascinating area of research.
