En este artículo se explica en qué consiste el desarrollo del proyecto Brazo Robótico. Un sistema de componente tecnológico, para la formación de los futuros ingenieros industriales de UNICATÓLICA. El desarrollo de esta interfaz se hará, principalmente, en el marco de la filosofía del software libre. Con la construcción e implementación del brazo robótico, los estudiantes podrán realizar actividades, como transporte de objetos o selección de piezas defectuosas en una línea de producción; entre otras. Se trata de una solución de carácter tecnológico que, además de innovar, contribuye a los procesos de enseñanza y es un motor motivacional para los estudiantes en el aula de clase. En el proceso se desarrollarán circuitos de control de los motores que le darán los diferentes grados de libertad al sistema. Para esto, se usará la plataforma de hardware libre Arduino. El resultado de esta implementación se verá reflejado en los egresados, quienes con esta formación, podrán destacarse en el ámbito laboral, tan competitivo actualmente. Abstract In this paper, the development of the Robotic Arm project is analyzed. A system of technological component, for the education of the future industrial engineers of UNICATOLICA. The development of this interface will be elaborated mainly within framework free software philosophy. With the construction and implementation of the robotic arm, students will be able to carry out activities, such as transportation of objects, selection of defective parts in a production  line, among other. It is a technological solution that, in addition to innovating, contributes to the teaching processes and is a motivational motor for students in the classroom.

This paper presents the development of the digital twin of an electro-pneumatic station composed with 3 pistons, to implement this station in virtual laboratories. The objective of this station is to have an economical alternative for the accomplishment of practices of automation that counts on the capacity to connect through Ethernet with PLCs of the mark of Allen Bradley and with all the PLCs that communicate under the protocol Modbus TCP. Later, in order to develop the digital twin presented in this paper, an electro-pneumatic physical station was taken from the Mechatronics laboratory at the Universidad Tecnológica de Queretaro, the development of this digital twin was done through the free software Blender, complementing it with programming in Python for the Ethernet TCP communication with the different programmable logic controllers. Finally, we carried out the validation of this project through the connection of both the digital twin and the physical station taken as a model, with a ControlLogix PLC. This work will allow the future to implement low-cost virtual laboratories in universities, training centers and interested institutions. The laboratories will have multiple practice scenarios that result in students better prepared in the programming of automated systems in the industry.

Convenient Interface

In the contemporary conditions, the implementation of computer parametric design to facilitate the design of 3D paper models is successfully realized using modern technological tools such as the free software Blender. Through the convenient interface of the program, the modeling of the desired three-dimensional shapes is greatly facilitated. This also applies to the automated process of constructing a drawing of the resulting polygonal 3D models, which in the future are assembled into three-dimensional paper models. This paper describes in detail the process of fine-designing 3D paper models using specific exemplary primitive, text, and with relatively complex form.

A symposium on the future of the International Latitude Service (I. L. S.) is to be held in Helsinki in July 1960. My report for the symposium consists of two parts. Part I, denoded (Mk I) was published [1] earlier in 1960 under the title “Latitude and Longitude, and the Secular Motion of the Pole”. Part II is the present paper, denoded (Mk II).

Second-epoch photographs have now been obtained for nearly 850 of the 1246 fields of the proper motion program with centers at declination -20° and northwards. For the sky at 0° and northward only 130 fields remain to be taken in the next year or two. The 270 southern fields with centers at -5° to -20° remain for the future.

Human And Mouse

Metaphase chromosomes from human and mouse cells in vitro are isolated by micrurgy, fixed, and placed on grids for electron microscopy. Interpretations of electron micrographs by current methods indicate the following structural features.Chromosomal spindle fibrils about 200Å thick form fascicles about 600Å thick, wrapped by dense spiraling fibrils (DSF) less than 100Å thick as they near the kinomere. Such a fascicle joins the future daughter kinomere of each metaphase chromatid with those of adjacent non-homologous chromatids to either side. Thus, four fascicles (SF, 1-4) attach to each metaphase kinomere (K). It is thought that fascicles extend from the kinomere poleward, fray out to let chromosomal fibrils act as traction fibrils against polar fibrils, then regroup to join the adjacent kinomere.

Freeze Etching

In his pioneering demonstration of the potential of freeze-etching in biological systems, Russell Steere assessed the future promise and limitations of the technique with remarkable foresight. Item 2 in his list of inherent difficulties as they then stood stated “The chemical nature of the objects seen in the replica cannot be determined”. This defined a major goal for practitioners of freeze-fracture which, for more than a decade, seemed unattainable. It was not until the introduction of the label-fracture-etch technique in the early 1970s that the mould was broken, and not until the following decade that the full scope of modern freeze-fracture cytochemistry took shape. The culmination of these developments in the 1990s now equips the researcher with a set of effective techniques for routine application in cell and membrane biology.Freeze-fracture cytochemical techniques are all designed to provide information on the chemical nature of structural components revealed by freeze-fracture, but differ in how this is achieved, in precisely what type of information is obtained, and in which types of specimen can be studied.
