Environmental impact of disposing of mouth covers, masks or respirators what alternatives do we have?

The objective of this article is to study the different options we have to combat the environmental impact generated by the use and disposal of face masks, masks or respirators due to the pandemic that we have been suffering for more than a year (COVID-19). The growing demand for this article of personal protection has also brought with it a growing carbon footprint that we are generating towards the environment, because most of the facial masks that are used are not degradable and must be discarded after a single use. To achieve environmental sustainability, we must work and investigate other options for masks, masks or respirators that can be reused or that are biodegradable, in order to minimize the negative impact on our environment. The masks that are analyzed in this article for the raw material with which they are made are N95 and fabric masks, especially cotton ones.

Theoretical construction of sustainable social awareness in mexican organizations

This article gives an account of the qualitative research process under the Grounded Theory strategy to generate a substantive theoretical construct called Sustainable Social Culture from instrumental records product of an immersion in the field in four industrial units (Martínez, 2020). The first findings raised questions that led to delving into the way in which industrial workers exercise agency and reflexivity in terms of sustainability. This theoretical construct rests on the Sociology of Organizations, Organizational Culture and Environmental Management that contribute to integrating categorical dimensions for their subsequent theorization and conceptual integration whose consistency, internal logic and validity are evidenced.

Pure® 24h and key water 14h. For plant height in 8h artesian well present a value of 175 cm, and the control with a value of 165 cm.

Influence of nitrogen and organic fertilization in the production of pungence in the crop of chile jalapeño (Capsicum annum), in greenhouse and open sky

Capsaicin and dihydrocapsaicin are responsible for 90% of the pungency of the fruit; the rest of the capsaicinoids participate to a lesser extent in the itching, but contribute strongly to the diversity of spicy flavors in the different species of Capsicum. In the present project the application of 7 treatment T1 = Chemical, T2 = Chemical + Bioferment, T3 = Chemical + Leached, T4 = Bioferment, T5 = Leached, T6 = Bioferment + Leached, T7 = Chemical + Leached + Bioferment, in greenhouse was evaluated and in open sky, a randomized block design with three repetitions was established. The variables evaluated were plant height, temperature, relative humidity, production weight, fresh weight, root depth, dry weight and pH. The data generated in this research indicate that the treatment that generated the most amount of capsaicinoids was the chemical treatment in the greenhouse with 37.7 ml of capsaicinoids and in the open sky with 36.96 ml.

Identify healthy and dead cells simultaneity of Bacillus subtilis MZ through to use of propidium iodide and acridine orange

The use of microorganism in a lot of process brings the development of new technologies. For guarantee the effect and the impact of the microorganism, even, the production rate when these microorganisms are involved in the production of a particular compound, become necessary know the number and condition of this organism. In the actuality, there are a lot of tools to identify this condition, since kits of staining cells, until, the best microscopy technology. But the use of this tools could become inaccessible due the high cost and in the case of de staining kits had a limited test. Then emerge the necessity to search and implement news methodologies to help us to identify health and death cells in different inoculs or products. In this work, we proposed a new technology for the simultaneous observation of healthy and dead cells trough the staining samples with propidium iodide and acridine orange using an optic microscopy with incandescent light and ultraviolet light.

Biogas production from cattle manure and sugar cane tip (Saccharum officinarum)

The purpose was to study the use of bovine manure mixed with sugarcane tip (Saccharum officinarum) in the production of biogas. A semicontinuous biodigester prototype of 1.7 m long and 6 in. diameter was designed and built with CPVC material. The waste was collected fresh for physical-chemical characterization, based on basic laboratory methods. Then the prototype was put into operation under controlled conditions. The biodigester was fed in two moments: the first, with 200 g of manure diluted in 750 ml of water and the second with a mixture of 200 g of manure and 50 g of cane tip, diluted in 750 ml of water. Finally, the volume of biogas produced and its quality were measured, with a water column pressure gauge and with a 540 multitec device, respectively. The results show that manure with the cane tip generates more biogas, this is attributed to the higher percentage of volatile solids in the mixture, whose organic components were converted to methane. The biogas production studied is a management option for waste from the agricultural sector and thus mitigate CO2 emissions in the region.

Determination of protein of edible insects

Mexico is a country with a wide variety of edible insects. Because of its high protein intake, insect consumption is proposed as a solution to hunger.
