In biotechnology has been concentrated to review alternative routes for the production of natural compounds. Plant cell culture systems are viable alternatives for the production of secondary metabolites that are of commercial importance in food and pharmaceutical industries. However, relatively very few cultures synthesize these compounds over extended periods in amounts comparable to those fo...

Combined heat and power systems are becoming more and more important, regarding their enhanced efficiency, energy saving, and environmental aspects. In the peresent study, three configurations of combined heat and power systems are intended as an alternative to separate production plant by considering environmental aspects. First and second laws of thermodynamics are adapted to the operatin...

Antibiotics are commonly used due to their antimicrobial activity and widely used for promoting growth, preventing diseases or therapy in poultry. The misuse of antibiotics in livestock production induces resistant bacteria into the environment. Therefore, the need to develop alternatives to antibiotics become increasingly important, that protect and improve global public health. The phytobioti...

Nuclear energy can be used as the primary energy source in centralized hydrogen production through high-temperature thermochemical processes, water electrolysis, or high-temperature steam electrolysis. Energy efficiency is important in providing hydrogen economically and in a climate friendly manner. High operating temperatures are needed for more efficient thermochemical and electrochemical hy...

Most societal and environmental challenges that humanity is currently facing relate to unsustainable consumption patterns and lifestyles. This unsustainability is sup‐ ported by consumerism and producerism that have high interests for fierce produc‐ tivity. This study presents a supply-demand marketing perspective based on the current literature and current market realities. Local food producti...

The process of agricultural development which takes place in Argentina has led to the loss sustainability. Mixed systems could be an alternative for improving productivity and, at same time, taking into account environmental cost. sowing sunflower (Helianthus annus L.) consociated with other species can generate greater biomass some cases, yield. Such practice is about differential harnessing r...

This paper presents a novel, multi-objective mixed-integer nonlinear programming (MINLP) model for a cell formation problem (CFP) with alternative means. Due to existing contradiction among objectives, three are considered: 1) Minimizing the total cost consisting of; intercellular movements, purchasing, operation, and maintenance; 2) maximizing the utilization of machines in the system; 3) mini...
