Modification of Da'wa through Internalization of Da'watainment in Prank Video Content on Youtube

Da'wa efforts in the era of disruption with the presence of online-based new media provide a space of expression for anyone to convey da'wa through unlimited creativity with various innovations. Da'wa is not always delivered seriously in a formal atmosphere but da'wa can be packaged in a relaxed manner, can be enjoyed in a relaxed and even entertaining way. Collaboration between da'wa and entertainment known as da'watainment is expected to be able to attract the millennial generation who are the largest users of Youtube media so that da'wa messages can be packaged through communication media that are close to the world of the millennial generation with concepts that are trending among millennials, one of which is prank. Prank content had gone viral after drawing a lot of criticism and protests because it contained useless substances and actually caused harm. Creative ideas are needed to modify useless content into useful content that is still interesting and entertaining. This study describes qualitatively descriptive from the data obtained from virtual observations on prank content and prank shalawat on Gus Aldi's Youtube channel which inspires millennial da'i-da'i in conveying da'wa messages through Youtube. In this content there is a varied structure in broadcasting shalawat as well as other messages of Islamic teachings which are also conveyed in a humorous, relaxed, and entertaining way.

Selective Synthesis of N-Acylnortropane Derivatives in Palladium-Catalysed Aminocarbonylation

The aminocarbonylation of various alkenyl and (hetero)aryl iodides was carried out using tropane-based amines of biological importance, such as 8-azabicyclo[3.2.1]octan-3-one (nortropinone) and 3α-hydroxy-8-azabicyclo[3.2.1]octane (nortropine) as N-nucleophile. Using iodoalkenes, the two nucleophiles were selectively converted to the corresponding amide in the presence of Pd(OAc)2/2 PPh3 catalysts. In the presence of several iodo(hetero)arenes, the application of the bidentate Xantphos was necessary to produce the target compounds selectively. The new carboxamides of varied structure, formed in palladium-catalyzed aminocarbonylation reactions, were isolated and fully characterized. In this way, a novel synthetic method has been developed for the producing of N-acylnortropane derivatives of biological importance.

„Góry łopuszańskie” w twórczości Seweryna Goszczyńskiego

In his two works devoted to the Podhale region (Dziennik podróży do Tatrów [Diary of a Journey to the Tatras] and Sobótka) Seweryn Goszczyński devotes a lot of attention to a description of the “mountains of Łopuszna”, part of the Gorce Range. The author is a precursor when it comes to presenting this space and one of few nineteenth-century writers who explore the varied structure of the Gorce landscape — natural and cultural. The article is an attempt to analyse the way Goszczyński presents Gorce, and the consequences of his creation for the analysed place.

Unstable cycles for the Burke–Shaw system via variational approach

In this paper, the systematical calculations of the unstable cycles for the Burke–Shaw system (BSS) are presented. In contrast to the Poincaré section method used in previous studies, we used the variational method for the cycle search and established appropriate symbolic dynamics on the basis of the topological structure of the cycles. The variational approach made it easy to continuously track the periodic orbits when the parameters were varied. Structure of the whole cycle in the dissipative system demonstrated that the methodology could be effective in most low-dimensional chaotic systems.
