The objective of this work is to reduce the moisture content of the guava (Psidium guajava) cut in slices, through the solar radiation characteristic in the area of the capital of the state of Zacatecas. Natural convection and forced convection were used to achieve the objective of this study. The selected guava comes from the municipality of Jalpa, Zacatecas. Moisture was evaluated with an OHAUS MB45 thermogravimetric scale, then the guava slices were placed in polymer mesh trays with dimensions of 34.2 cm long and 24 cm wide. They were introduced inside a transparent dryer with dimensions of 74 cm x 80 cm of base and a frontal height of 13 cm and posterior of 40 cm. A Checktemp 1 thermometer was placed inside the dryers to evaluate the temperature in the drying process. The initial humidity of the guava was 50.51%, the final moisture obtained in the natural convection was 8.08%, while in the forced convection it was 8.32%, after 8 hours of drying.

The aim of the present study was to evaluate some physicochemical characteristics of large scale composting process of tequila agave bagasse, and also quantify the population dynamic of bacteria, fungi and actinomycetes througout 300 days. A large windrow of agave bagasse of approximately 195 m (~331 t) was set and regularly monitored. Thereafter a pile section was reubicated to continue the evaluation. The windrow was sampled every 15 days and the following parameters were measured: moisture content, temperature, pH, electric conductivity (EC), the organic matter (OM), C/N ratio and the population dynamic of bacteria, fungi and actynomicetes in colony forming units. From the very beginning of composting the temperature of the windrow reached the thermophylic phase (>45 °C) and continued up to 270 days. However, at the end of the study the temperature felt down till 42 °C due to the reduction on moisture content (<30%). The highest EC registered was 1.5 dS/m; the OM remained between 70-35% and the C/N ratio varied between 96.9 initial and 29.6 final. Actinomycetes were the most dominant group especially in the last weeks of composting, which infers the possibility of using this type of compost in soil bioremediation.

A solar collector with evacuated tubes was developed to heat air from room temperature until it has the capacity to be used in drying processes. The instantaneous and global thermal efficiency of the equipment was studied, as well as the behavior of the outlet temperature at different air flows. Measurements of inlet and outlet air temperatures, irradiance were taken, and mass flow were determined. The amount of heat absorbed by the air was calculated and, in relation to the irradiance, instantaneous efficiency was obtained to later determine the overall efficiency. The device consists of a polypropylene tube where 5 evacuated tubes were placed. Air was flowed into each of them with an arrangement of a stainless-steel conduit with thin-walled tubing. For various air flows, thermal behavior curves were obtained, where increases in air temperature between 30°C and 50°C were observed, reaching outlet temperatures of up to 90°C. Efficiencies were calculated from 40% to 60%, for high and low operating temperatures, respectively. The increase in temperature resulted in a linear trend, facilitating the design of instrumented dryers and their control.

The objective of the research is the physicochemical characterization of bioplastic membranes based on Nopal (Opuntia ficus-indica) to determine their possible applications. The tests performed for the characterization were: permeability, solubility, resistance, thickness, drop test and chemical analysis with the infrared spectrophotometer. Today, new and better alternatives are sought in obtaining different polymers that benefit humanity and the environment. Recycling is an option but it is not a very effective alternative for all plastics, however, biopolymers are a solution from the origin of the problem since the vast majority of them their biodegradation time is much less than that of a common plastic. Biopolymers, which for the most part come from renewable resources so they become an interesting alternative for the plastics industry. The physicochemical properties of the Nopal-based membranes (Opuntia ficus-indica), are similar to synthetic plastic membranes, being a viable alternative to replace them, thus contributing to society, with a better quality of life being environmentally friendly.

The work shows the methane production that was obtained by combining different substrates of cow and rabbit excreta. Five biodigesters of the Batch type were used for the study, in which they were filled with different proportions of cow, rabbit and water excreta, in order to quantify which combination produced the greatest amount of methane. In order to know the amount of moisture free material and the fraction that has to produce biogas, the dry mass and volatile mass of cow and rabbit excreta were determined. During the test, readings of pH, pressure, temperature and composition of the biogas were taken. In the end it was obtained that the substrate formed by 10% of cow excreta, 40% of rabbit excreta and 50% water, presented the highest amount of methane of all the combinations.

In this study, the photocatalytic degradation of azo dye Acid Black 52 using different mixtures of semiconductor oxides as a catalyst is reported. The experimental system consisted of a Batch reactor in which the azo dye, the semiconductor oxides and the hydrogen peroxide were mixed, whose concentrations were 0.1 mM, 100 mg/L and 65.2 mM, respectively. The mixture was homogenized by a magnetic stirrer and the pH was adjusted to 3.0. The initial volume was 500 mL. A white light lamp (127 V, 60 Hz, 362 mA, 60 W, 60 lm/W) was placed coaxial to the reactor and turned on to activate the catalyst. Samples were taken every 30 minutes to measure the absorbance, for this purpose a HACH DR3900 spectrophotometer was used. After 180 minutes of treatment, the best result, 60% degradation of the azo dye, was obtained with the mixture manganese oxides-iron oxides. The purpose of this work was to completely transform the pollutant into carbon dioxide, to avoid its adverse effects on the environment and human health, using catalysts excited with visible radiation.

Floating photocatalysts have caused interest due to the benefits they provide. For example, the floating support has characteristic lightness and flexibility; while the photocatalyst has the advantage of being able to interact with sunlight without the need of stirring or oxygenation. In this paper, a floating photocatalyst based on a TiO2/ agglomerate composite is evaluated. The agglomerate is made from post-consumer packaging of multilayer containers. The catalyst was prepared by synthesizing of titanium dioxide powders with phase mixture anatase/rutile. The photocatalyst powder was attached to substrate surface using a varnish obtained by dissolving post-consumer polystyrene containers in toluene. The photocatalyst has different phase A-R (Anatase-Rutile) ratios. The approximate size of the nanostructure is 13.29 ± 3.28 nm, calculated using UV-Vis spectroscopy, the bandgap has values ranging from 2.56 eV to 2.90 Ev. The agglomerates have a rupture modulus of 14.95 N/mm2; they are hydrophobic materials and possess dimensional stability against changes in humidity (length) less than 10%, chemical resistance, are flame retardant. The TiO2/agglomerate composite is used for the photocatalytic degradation of a model pollutant (methylene blue) using sunlight.

Some composts can produce phytotoxins that inhibit the development of plants and the absorption of nutrients by an excess of indoleacetic acid if the compost is not mature. In the present work, the objective is to evaluate the quality of the compost by means of direct tests of phytotoxicity and agronomic quality with different composts. To determine the quality as organic compost and vermicompost fertilizer were considered physical, chemical and biological variables according to existing manuals. The results obtained for these variables were: In the physical, chemical and biological variables, all the parameters are fulfilled according to the norm. Seed germination of vegetables increased with respect to the control in 14.93%, possibly due to the presence of some root development promoter found in the compost. With regard to survival the witness was inferior by 3.08% Although the amount of nutrients found in composts are not so high, they comply with the minimum requirements of the regulations to be used as a substrate in horticultural applications. Conclusion, the results of this study indicate that the compost elaborated with any type of residue can be used as a substrate in seedbeds of chili, onion or other vegetables to induce germination and accelerate the development of plants.
