Now days, water expenditure in households has increased due to the improper use of water in various activities such as: gardening, car washing or household cleaning. This causes water scarcity and an increase in household economic expenditure. In order to deal with this problem, a mathematical model was established, in which the amount of water collected during the year is calculated in order to carry out all the aforementioned activities, in which variables such as catchment area, Rainfall, expenditure on a house-room and the size of the tank. The calculations were made for a houseroom made up of five people, which gave us an expense of 600 liters per day (120 liters per person), liters of water distributed as follows: 240 WC, 120 shower, 60 clothes, 30 kitchen and 150 irrigation.

In order to attenuate the added noise by electric network used by myoelectric signals acquisition equipment, in this research work, it is developed an IIR digital filter implemented on FPGA. This filter removes a specific spectra frequencies without adding noise to the signal, which allows a better performance in the usage that is given to the signals. The filter coefficients are taken and proved from MATLAB functions. Then, those are transferred to the filter design in the FPGA. For this purpose, it was used a Basys 3 of Xilinx Artix-7 family and the design was implemented in Vivado Design Suite. The filtered signal does not present additional noise and it was eliminated the desired frequency.

In recent years has been suggested that foliar application of H2O2 alleviate symptoms of drought in several crops. The aim of this work was to assess the effect of exogenous H2O2 application on Capsicum annuum L. crop as a protective treatment to further water deprivation. DNA methylation (5-methylcytosine percentage), stomatal density, number of leaves and photosynthetic activity were the variables evaluated.

Over the year's new techniques have been developed to measure the photosynthetic rate of plants in order to predict yields in crops or to establish strategies for the production and use of energy inputs such as supplemental light and carbon dioxide mainly. In recent years' techniques, have been developed that measure photosynthetic activity in plants at the level of a single leaf or even the entire plant, the latter being the technique that best fits the actual behavior of plants. The objective of this study is to propose a low-cost technique to measure photosynthesis in complete plants. This is done through the coupling of two techniques already developed: one is the measurement of the canopy CO2 exchange rates (CCER) and the other is the measurement of leaf surface using digital photographs. As a result, a CO2 monitoring chamber with polycarbonate panels was obtained in which the CO2 uptake of a tomato plant was measured, also it was possible to measure the leaf surface. Finally, using this system with tomato plants, we observed that at a temperature of 18 °C inside the chamber, the photosynthetic rate is higher than at 28 °C and 38 °C.

The Sol-Gel method is one of the techniques used to synthesize materials with a bimodal and hierarchical pore structure, which can be verified by different characterization techniques. The techniques of characterization of the materials of Silica exhibiting multimodal hierarchical porosity are Scanning Electron Microscopy (SEM) and Nitrogen adsorption-desorption isotherms, which serve to corroborate that there are mesopores with diameters in the 2–4 nm range in the internal part of the silica particles originated by the supramolecular molding by the surfactant. Furthermore, textural mesoporous in the 9–22 nm range are a result of voids between silica particles. In addition, we can distinguish this type of network mesoporosity from the textural mesoporosity originated by the spaces or voids left between the silica particles, which falls in the 9–22 nm range. The alkylammonium surfactants and Poly (ethylene glycol) have been used to control the internal structure and the aggregation of particles, respectively.

Due to the indiscriminate use of pesticides and the growing demand for safe products without the presence of agrochemicals, plants have been considered as an appropriate field to search for new structures with less environmental impact and potential for agricultural pest control. Specialized metabolites are well known for their relation with the plant defense response mechanisms, being induced in response to biotic and abiotic stresses. Exhibit biostimulating activity and highly induce plant defense phytoalexins, suggesting that treatment of plants with metabolism modifying factors could be a feasible way to trigger the biosynthesis of bioactive metabolites.

Astyanax mexicanus is a Mexican native fish that have surface and cave phenotypes. Due to their distinctive characteristics caused by and independent evolution it is a model for studies on evolution and development, and it could be used for cross-species comparisons in aquaculture since it is close related to economically important species. A. mexicanus have been in the aquarium trade in the United States since the early 1940s, however, there are no reports of its production inside Mexico. We propose a breeding system to enable the establishment of experimental and commercial lineages available for trade. The system was made in a rack structure, with interchangeable modular fish tanks. To induce the spawning of the species, an overnight temperature change its needed, requiring an increment for the cave fish and a temperature reduction for the surface fish. A temperature regulation trial was performed, changing the temperature from 26°C to 22°C overnight and turning it back to 26°C at the next morning. The obtained temperature gradient was adequate to give the spawning condition of the species as stated in previous studies. The proposed system its adequate to start breeding trials with different A. mexicanus populations.

The efficiency of a functionalized Disordered Mesoporous Silica-1 (DMS-1) to remove mercury ions disperse in water was evaluated. This material was functionalized using 3-mercaptopropyltrimethoxisilan as the source of thiol groups using the post-synthesis method. The aforementioned sorbent system was characterized using N2 adsorption-desorption isotherms, Fourier Transform Infrared spectrometry (FTIR), Thermogravimetric Analysis (TGA), Small Angle X-Ray Diffraction (SAXD) and Scanning Electron Microscopy (SEM). These characterizations showed that the functionalized meshes possess the suitable microstructure and textural properties to be use as an adsorbent to remove mercury ions from water. Adsorption experiments showed a significant reduction of mercury ions of up to 99% of the total concentration contained in a synthetic solution (132 mg/l).

The limited availability of water quantity and quality for human, agricultural and industrial use is a common problem faced in several places. Natural phenomena and mismanagement of watersheds affect the hydrological cycle and natural resources contained therein; the effects are present and the consequences are severe. Floods are one of the common problems that cause enormous economic, social and human losses. With the implementation of hydraulic structures for flood control, it has recently received much attention. Gabion dams have been successfully used in watershed management and have proven to be a viable solution for flood control. They are used to attenuate hydrograph by providing temporary storage. By using these dams, hydrograph final output with lower and longer maximum flow occurs. However, their behavior has not been well understood because the characteristics of building materials affect their behavior in the control of hydrological processes. Therefore, the main objective of this work was the aim of this work was to determine the effect that the size and shape of the rocks gabion dams have on the control of flow and sediment retention in the channels. Experimental results show that both the shape and size of rocks gabion dams influence the rate of flow and sediment retention. A bigger rock had lower resistance to flow and allowed the passage to a greater amount of soil particles. An influence of the shape of rocks larger percentage sediment retaining angled rocks also found. In addition, an effect of the channel slope on the behavior of gabion dam to control hydrological processes found.

A paper-based electromechanical system (PB-EMS) driven by means of the Lorentz force excitation method is introduced in this work. Such a system consists of a paper-based cantilever beam that is fabricated using conventional printer paper, printable electronics, and standard cutting tools. The results show the feasibility to develop PB-EMS using the Lorentz force actuation principle. In addition, the influence of the driven current on the dynamic response of the PB-EMS is analyzed. A softening effect is identified when increasing the magnitude of the excitation current. This softening effect is evaluated using a lumped model. The spring constant as a function of the excitation current exhibits a linear relationship. Moreover, the frequency response of the system is experimentally studied by using image processing. The maximum variation of the resonance frequency is measured as 16.5% of the nominal frequency when using an excitation current of 300 mA. Thus, it is expected that the Lorentz force excitation can be applied to both drive and tune the behavior of the proposed PB-EMS.
