In the agricultural sector of the municipality of Guasave, diesel pumps are currently used to irrigate the various crops, this due to the lack of water that has occurred in recent years. To do this, these pumps are mostly manufactured with very rustic physical structures and only with analog markers that are not very precise. This situation keeps the equipment unprotected and only shows parameters analogically, this makes the process inefficient. With the present project, we designed, developed and simulated a prototype of a system that evaluates and monitors the physical parameters that influence the operation of different thermal machines used for pumping. To achieve the above mentioned, a series of sensors were installed, the signal is sent to Raspberry Pi 3, in which the data is processed, stored and shown to the user of the equipment through a graphic interface. A possible improvement of this system in the future would be to create a mobile application, which in real time, could alert the user of possible failures, decreasing the side effects on the environment, optimizing crop rotation for the continuous improvement of the competitiveness of the agro-industrial sector in northern Sinaloa.

The tomato (Solanum lycopersicum) is one of the main vegetables grown in Sinaloa. This crop is affected by pest insects, such as the white fly (Bemisia tabaci). The objective was to evaluate the effect of different doses of neem-based biorational insecticide on the population density of whiteflies. A completely randomized design was established to evaluate the population density of whitefly adults. The treatments evaluated were different doses of neem leaf extracts (NLE): (T1) control, (T2) 200 g NLE•L-1, (T3) 300 g NLE•L-1, (T4) 400 g NLE•L-1 and (T5) 500 g NLE•L-1. An analysis of covariance was applied to the data obtained and the difference between the means was evaluated using the Tukey test with an α=0.05. Neem extracts had an effect on population density (p≤0.05), by reducing the population as the concentration of the extracts increased. T5 presented the highest reduction with 43.56%±1.6, while T4 presented a reduction of 39.27%±1.7, compared to the control. However, the application of T5 causes damage to the plant, so it can be considered that T4 is more suitable for its application. Therefore, neem extracts had an effect in controlling the whitefly population.

The present experimentation is the evaluation of noise levels in laboratories, classrooms and departments of a Higher Education Institution. Its objective is to identify and evaluate the working conditions to which workers and students are exposed when performing tasks. The study was conducted based on the official Mexican Standard NOM 011-STPS-2001 "Conditions of safety and hygiene in workplaces where noise is generated". Using a TES 1353S sound level meter for 4 weeks, evaluating 16 zones, in 2 periods. As a result, it was obtained that 6 of the 16 zones evaluated exceed the maximum permissible exposure limits. And recording discomfort and lack of concentration in the activities to be carried out on workers and students. As a recommendation, the implementation of periodic medical examinations and personal protective equipment for the personnel, in addition to the evaluation of noise levels in the preventive maintenance of the institution.to make the activities more comprehensive.
