The refrigeration systems are of great importance in the daily life of the human being, due to the fact that it is necessary to have cold storage systems for different processes and perishable products preservation. The generated electric power as an alternative source has been used for refrigeration systems involved in sustainable development programs. The aims of this research were to characterize a cooling system powered by solar panels and that pretend to improve the quality of life. Refrigerating machines that use alternative sources of energy contribute to sustainable development, however, those that do not use it have a greater environmental impact. The solar refrigerator prototype has a quantitative-qualitative approach in deductive processes based on interpretation and data collection. This was carried out using own materials for the refrigerators construction that allow obtaining a compact configuration, presenting, pressure-volume operation curves and autonomy of the system with maintenance similar to conventional refrigeration systems. The refrigeration system is intended to be used in marginalized areas, low-income organizations and in support unprotected populations.

The consumption of avocado is of great importance in the daily diet of the human being, since this fruit contains high levels of Omega 3 and various vitamins (B6, B9 and E) and minerals (magnesium, iron, zinc and phosphorus). Today, Mexico is one of the main avocado producers worldwide. However, the high demand and the low production of this fruit makes the price of avocado more expensive and, therefore, the Mexican population reduces its consumption and seeks nutritional alternatives. For this reason, this research aimed to propose the manufacture of solid avocado tablets (based on pharmaceutical techniques) by granulating and compacting the dehydrated powder of this fruit. This was carried out under a mixed approach by applying quantitative and qualitative technologies to systematic, critical and empirical processes in order to choose the best granulation technique, the ideal binder and the type of compaction to use to achieve solid tablets using dehydrated avocado powder. This tablet aims to preserve the same nutrients as natural avocado and reach all sectors of the population to generate a sustainable and human survival environment.

The article discusses the implementation of constant updates in the management of the National College study programs, with the main goal to advance in a constantly changing Industry sector that requires engineers who could adapt themselves to the tendencies that build solid relations between forming Institutions of engineers (colleges) and the Industry sector, with the purpose of creating sustainable projects obtain the technical and technological development to help our society. The article presents a stage in which the Engineering students and the companies obtain the firmness of an ideology based on the commitment to develop or to adapt projects focused to constructing a sustainable environment that would impulse the technology in the local region, modernizing it. Many studies show the necessity of teaching and transmitting a development capable of guiding the Engineering student’s community to the path of a harmonic evolution with the society and the environment.

Pharmaceutical industry produces safe, effective, affordable, and quality medicines used to guarantee a healthy life and promote the well-being of the entire population in a sustainable way. Currently, the solid dosage form is the preferred formulation for human use. However, the large scale production of these medicines it requires well-tested formulation and appropriate equipment because any substantial variation in the development of the pharmaceutical product can alter the final quality of the product, causing the entire manufactured batch to be discarded. For this reason, this research aimed to analyze and understand the behavior of the variables involved in the wet granulation process while scaling from a laboratory system and a production line unit to transfer the results obtained to a large-scale production unit of solid dosage forms to meet the health needs of the world population. This study was carried out under a mixed approach applying quantitative and qualitative technologies to explain and predict the behavior of the involved variables while scaling from a laboratory system to a production line unit. It was found that there are some regularities and causal relationships between geometric, kinematic, and dynamic similarities.

The morphing type wings aim is to improve their aerodynamic performance in each flight condition as a bird would do it, this improvement is obtained by modifying its shape through intelligent mechanisms. Optimizing and dynamically adapting the shape of the wings to various flight conditions, leads to many unexplored possibilities for improvement that have been identified beyond current model test demonstrations. This research aimed to analyze the most prominent examples of morphing concepts in models of previous wing experimentation. Morphing concepts have certain limitations on a large scale, however some consortia have chosen to investigate it, in full-scale models. In this work, a mixed type methodology is presented covering qualitative and quantitative research studies on morphing-type wings. Finally, it is mentioned the importance of continuing to investigate these models and it is considered that the implementation of real models will aid to optimize the conditions leading to sustainable development models.
