Latent heat storage has shown a great potential in many engineering applications. The utilization of latent heat storage has been extended from small scales to large scales of thermal engineering applications. In food industry, latent heat has been applied in food storage. Another potential application of latent heat storage is to maintain hot beverages at a reasonable drinking temperature for longer periods. In the present work, a numerical calculation was performed to investigate the impact of utilizing encapsulated phase change material PCM on the temperature of hot beverage. The PCM was encapsulated in rings inside the cup. The results showed that the encapsulated PCM reduced the coffee temperature to an acceptable temperature in shorter time. In addition, the PCM maintained the hot beverage temperature at an acceptable drinking temperature for rational time.

The author examines body politics in Nazi cinema and propaganda movies (medical short films and materials filmed in the Polish Ghettos) in terms of constructing the visual identity of a nation in opposition to the allegedly non-normative bodies of Jews and mentally ill persons. The author connects the visual material with notions of biopolitics (Foucault, Agamben, Esposito).

The growing development in the thermal engineering and nano-technology, much attention has been paid on the thermal properties of nanoparticles which convey many applications in industrial, technological and medical era of sciences. The noteworthy applications of nano-materials included heat transfer enhancement, thermal energy, solar systems, cooling of electronics, controlling the heat mechanisms etc. Beside this, entropy generation is an optimized scheme which reflects significances in thermodynamics systems to control the higher energy efficiency. On this end, present work presents the slip flow of Jeffrey nanofluid over a stretching sheet with applications of activation energy and viscous dissipation. The entropy generation features along with Bejan number significance is also addressed in present analysis. Buongiorno model of nanofluid is used to discuss the heat and mass transfer. The formulated flow equations are attained into non-dimensional form. An appropriate ND MATHEMATICA built-in scheme is used to find the solution. The solution confirmation is verified by performing the error analysis. For developed flow model and impacted parameters, a comprehensive graphical analysis is performed. It is observed that slip phenomenon is used to decays the velocity profile. Temperature and concentration are in direct relation with Brownian motion parameter and activation energy respectively. Entropy and Bejan number have same results for greater diffusion parameter.

The analytic focus of this article is the highly fashionable ‘infinity pool’, treated here as a visual-material realization of the cultural politics of super-elite mobility. The article is organized around a three-step analytic structure. First, I demonstrate how the infinity pool is mediatized as a status marker, and thus circulated and normalized. Second, I pinpoint the semiotic and ideological ways the infinity pool emerges as a mediated practice. Third, I examines how the infinity pool is also remediated on Instagram and thereby broadcast anew. Throughout, I evidence my analysis with visual texts drawn from a range of commercial, situated and digital media sources. My primary objective is to show how the infinity pool, as a mediatized, mediated and remediated practice, feeds the global semioscape, that more informal, often banal plane of cultural circulation where images, ideas and aesthetic ideals seed themselves all over the place. In this way, and however frivolous or innocuous infinity pools may seem, they also spread a particularly privileged way of looking at, and being in, the world.
