    <p>The population growth of the last decades has created the need to look for new ways to increase the productivity of crops. Knowing this, several studies began to be carried out in order to analyze the influence of electromagnetic radiation on the development of plants. With that in mind, the present work presents an experiment carried out to analyze the influence of the irradiation of an electromagnetic wave of 2.3625 GHz in the development of a corn crop by comparing the growth of this plant exposed to this extra radiation with another that is only exposed to the ambient radiation. The results demonstrate that the plant exposed to the radiation set at a specified frequency has a decrease in root size. </p&gt

    <p>Analog to digital converters are widely used in all kinds of areas since they can ensure a communication between the computer and the external world, the development of a 4-bit A/D flash type converter as the main objective for this article follows the same purpose. The paper was planned in a way that, with a great number of tables and graphs, most people would be able to understand and replicate the desired results correctly.  The simulation, which is the main part of the development of the article, was done using a software called LTSpice, a program with several tools and components that made possible to assemble a converter, besides that, the software also has a tool that allows to create new components, in which it was developed full custom AND and OR logic gates based on CMOS technology. At last, the results show satisfactory graphs that prove the functioning of the converter.  </p><p> </p><p> </p&gt
