Water requirements in food production and agroindustrial activities, as well as society, is a growing demand. Our country, Mexico, is one of the 80 countries with the most irrigation infrastructure in the world, ranks seventh, although environmental difficulties such as overexploitation of aquifers, salinity and pollution affect irrigation areas. Taking into account the increasing concentration of boron in surface and groundwater and the need to treat seawater, which contains large amounts of this element, it is important to develop effective technologies for the removal of boron. Unfortunately, there is no simple and economical method for this task. The great difficulty in selecting this method is the fact that boron appears in water in several numbers of chemical compounds and its concentration varies from environmental conditions from one site to another. Treating water with high concentrations of boron will allow this resource to be used in agricultural crops It will be possible to obtain a water treatment design, in which a chemical procedure is established to remove boron by precipitation in batches so that the cost of the treatment is economic, the second purpose will be to obtain a calculation memory to determine the concentration of Reagents to be used once the initial concentration of boron is known.

Plants are the main source of food for humans, their production and distribution are vital. The biotic and abiotic stress causes losses in the production, causing from bad organoleptic characteristics in the product to losses between 70– 80% of the harvest.

Structural analysis for the design of bridges begins by determining actions acting on the structure, which are distributed through the superstructure, causing particular effects for each structural element of composition. Vehicle load is the main live action acting on the superstructure of a vehicular bridge. To estimate the distribution of this charge in the structural elements, different distribution models are used, which in its simplicity, they have limitations and restrictions for your application. Examples of these are the Courbon method and its variations, Homberg chart, standardized methods as coefficients AASHTO (American Association of State Highway and Transportation Officials), AASHTO LRFD (Load and Resistance Factors Design), Communications and Transport Secretariat (SCT by its Spanish acronym) standards, OHBDC (Ontario Highway Bridge Design Code) y CSA (Canadian Standard Association). The standardized methods mentioned above are mainly governed by a D-value defined by the geometric and material configuration of the bridge, as well as the specification of design load, which correlates the particular effects in the elements of the superstructure of these systems from of an analysis global, with the effects generated by one wheel line of load applied to an element particular in a particular analysis of the element. The criteria governing the structural design of bridges in Mexico is currently proposed by the SCT standards. Which has the criteria used in the AASHTO standards as a basis, it was developed for the specific conditions of the USA. This paper analyzes the principles and peculiarities of the above criteria, and presents the results of an analysis carried out for a particular structure using different criteria while proposing a methodology for the development of a model of load distribution in these systems, considering the specific conditions of Mexico.

The present work shows the design and implementation of a controller based on Fuzzy Logic for pH regulation using an S7-1200 Programmable Logic Controller (PLC) as a processing element. The inputs of the controller are the current error (desired pH - current pH) and the rate of change in error (current error - previous error). On the other hand, the output is given by the activation time of an on-off dosing pump, which was adjusted to a constant flow of 2.5 liters per hour. The controller calculates the time that the pumps must be on or off so that the process variable reaches the desired value. A Delta Human Machine Interface (HMI) are used to acquisition data and process parameters configuration.

The industrial robot applications are very important for global industry. Major of the robots are using an electrical actuator, due its high precision. The advantage of electrical actuators is the low power-weight rate. The pneumatic actuators are used for industrial applications, but its precision is very low. The major problem with pneumatic actuators is the highly nonlinear behavior of the air, due the expansibility and compressibility properties. This work is focused in design a pneumatic robot with 4 degree of freedom, including the hardware interface to control the pneumatic actuators, and some test are developed with a Texas DSP Delfino C2000. The results show a pneumatic robot design including electronic hardware and an algorithm control.

Every day petrochemical activities, spills, and leaks in the storage pipes contaminate the soil. For example, if a spill occurs or there is a leak of a pipe near where there is a building, the mechanical properties of the soil can be affected, causing economic problems or, in extreme cases, loss of life due to lack of stability in the structure. It is possible to take decisions if we know the behavior of the soil in contact with some contaminant. In Mexico, some works have been initiated that evaluate the physical and mechanical properties of the soil contaminated; however, this information cannot be generalized because each place has various soil formations. In this work, we present a study of a high compressibility clayey soil (CH) contaminated with diesel to evaluate its impact on the limits of consistency and the compressibility index of the soil. We found that the liquid limit decreased when the soil was contaminated with diesel. The results showed that in the consolidation process in the contaminated soil a decrease in the compressibility index of 19% compared to the soil with water.

In this short paper we give a proof that the Banach—Mazur distance between quadrilaterals and triangles is smaller than 2. We also study the Banach-Mazur distance between the regular pentagon and the triangle. We give a detailed proof about the Banach-Mazur distance between the regular pentagon and the triangle, which was previously observed by some others.

The study of the rhizosphere with conventional methods can lead to errors in the analysis of the soil-root interface. The aim of this work is to design and carry out a versatile Rhizobox system that allows the study of different crops and types of research. For this purpose, a model that allows different adjustments in the support and development compartments of the rhizosphere and an array of access points in the lower compartment to easy aquare samples in situ were designed. The above, aims to generate an information platform that basis to generate strategies for performance of crops.

The figure digitization and reconstruction have gained a widely usage in industrial and commercial applications. In this paper a low cost 3D scanning prototype with an embedded system is proposed to be used in piece surface digitization. A reconstruction algorithm in MATLAB is used to manage the piece raw data, then a 3D printer software is used to reconstruct the image and resize the output figure. A Time-of-Flight ranging sensor is employed to detect the surface shape and capture it in raw data. A fast development board is the prototype manager to control motors, sensor and computer commination. The system function and data treatment process are described as well. The scanner accuracy depends strongly on the sensor resolution and its final result is related to the step number achieved by mechanical system.
