Ultra-high-pressure homogenization (UHPH) is an emerging technology with applications in fluid processing. Although, this technology is based on the same principles of conventional homogenizers, the new designs and use of valve construction materials have made it possible to reach pressures of 350 to 400 MPa. The advantages of UHPH include the reduction of the particle size, an increase in the useful life through the inactivation of microorganisms and improvements in functionality due to the increase in the capacity and stability of the emulsion, with minimal effects on the nutritional value and sensory characteristics. Also, the thermal effects are less due to the treatment time (less than one second). UHPH technology is a sustainable process that has a potential application in the cosmetic, pharmaceutical and dairy industries. This review shows an overview of some recent studies of the...

Approximately 90% of the sixty thousand museums that exist around the world have closed either totally or partially due to Covid-19. In this new era, one of the main challenges that museums face is staying connected with their public. This study seeks to identify evidence of how prepared Lima’s museums are to face new challenges like that presented by Covid-19, and what recommendations they should follow in terms of research, communication and education. Following an exploratory discourse analysis based study, a list of recommendations was compiled and grouped into three categories: management of virtual collections, virtual visits, and the use of social networks as learning spaces. This research shows that those museums which implement strategies related to their research, communication and educational functions, as well as the use of information and communication technologies, will b...

Historically, virtual whiteboards emerged with the rise of digital technologies in the late twentieth and early twenty-first centuries, offering an interactive alternative to traditional physical blackboards. The virtual whiteboard, an emerging tool in distance education, is the object of study of the present research, conducted in a public university, to evaluate its use in the teaching of basic mathematics to 36 students, using a quantitative approach, non-experimental design and descriptive sub-design. In the instrumental dimension, teachers showed limitations in the technical handling of the tool. Cognitively, the integration of the virtual whiteboard in teaching strategies was minimal. Behaviorally, students interacted little with the tool, and axiologically, no significant change was perceived in the educational values promoted. These results suggest the need to train teachers in t...

Electrical power consumption in Peru increased on average by 5.1% between 2002 and 2011, while demand increased from 2 700 MW to 4 800 MW as a consequence of the increase in GDP. On the other side, photovoltaic (PV) technologies have been used in Peru for power generation in a few thousand small solar home systems (SHS) in the last 25 years, through various rural home electrification programs. This has permitted to accumulate a large amount of experience, which would open the possibility to consider the installation of larger PV systems with connection to the grid. Likewise, in the last five years, power generating plants have been installed to inject power directly in the National Power Grid (SEIN, from its Spanish acronym) without any substantial intervention of the national engineering community. One can see that in this scenario of technological evolution, PV technologies is present ...
