    El Instituto Técnico Industrial Francisco José de Caldas (I.T.I.) cuenta con una población en el grado noveno de 440 estudiantes con habilidad innata en el lenguaje y el entorno digital (nativos digitales). Ahora los jóvenes tienen la capacidad de investigar, crear, informarse y esto los lleva a organizar y aprender en un mundo interconectado a la inmediatez, pero en ocasiones son rezagados a meros observadores en un sistema educativo que no les satisface ni motiva. Teniendo en cuenta lo anterior se hace evidente la necesidad de contar con herramientas que potencien la construcción del conocimiento a través del aprovechamiento de las nuevas Tecnologías de la Información y la Comunicación (TIC), como mecanismo de lenguaje, desarrollando habilidades y destrezas metacognitivas. Esto se puede lograr aprovechando el uso de dispositivos digitales con los que están familiarizados en su vida cotidiana, de manera que los aprendizajes que se generan sean significativos. Con la revisión de la literatura especializada, se encontró poco sobre la conciencia del propio aprendizaje por medio de Twitter en estudiantes de educación media; sin embargo, se apoya la idea de que se puede abordar la metacognición con estrategias basadas en las TIC y la web 2.0, lo que abre la oportunidad para mostrar que los estudiantes pueden ser conscientes de su aprendizaje utilizando como herramienta la red social Twitter.Universidad Libre – Facultad de Ciencias de la Educación -- Maestría en Educación con énfasis en Psicología Educativa1.415 / 5.000 Resultados de traducción The Francisco José de Caldas Industrial Technical Institute (I.T.I.) has a ninth-grade population of 440 students with innate ability in language and the digital environment (digital natives). Now young people have the ability to investigate, create, inform themselves and this leads them to organize and learn in an immediatly interconnected world, but sometimes they are left behind as mere observers in an educational system that does not satisfy or motivate them. Taking into account the above, the need to have tools that enhance the construction of knowledge through the use of new Information and Communication Technologies (ICT), as a language mechanism, developing skills and metacognitive skills becomes evident. This can be achieved by taking advantage of the use of digital devices with which they are familiar in their daily lives, so that the learning that is generated is significant. With the review of the specialized literature, little was found about the self-awareness of learning through twitter in high school students; however, the idea that metacognition can be approached with strategies based on ICT and web 2.0 is supported, which opens the opportunity to show that students can be aware of their learning using the social network twitter as a tool

    The research project was carried out in the hacienda "LAS LOMAS" located in the Province of Cotopaxi, Canton Latacunga, in the Parish of Tanicuchi; which was carried out in order to evaluate a Fixed Time Artificial Insemination Protocol "IATF", using as main instruments the intravaginal implants with progesterone "CIDR" applied on day zero plus the administration of 2 ml of estradiol benzoate IM, On the seventh day the intravaginal implants were removed and 2 ml of Estrumate (F2 &) was applied, which is a prostaglandin, on day eight, 1ml of Estradiol Benzoate BE was applied, on the 9th the devices were removed, and we applied 3ml of Gonadorelins "Conceptal" 15 to 30 minutes before the AI, and finally it was inserted on day 10 or it is calculated between 54 to 58 hours after implant removal, for which twenty-seven (27) vaconas with the same characteristics were selected in terms of body condition, diet and management conditions. The objective of the research was to evaluate the animals that are pregnant, that return to natural estrus and the cyclicity of the post IATF protocol. The vaconas are of Holstein breed, ages between 15 and 18 months and an ovarian corpus luteum condition for all. Finally, on the 45th day after the completion of the treatment, a gynecological check-up was performed on all the vaconas to know the presence or absence of pregnancy. The characteristics of the animals showing estrus, the pregnancy and the return of the estrous cycle were evaluated. It was verified that within the group under treatment there were 17 vaconas in gestation n, 10 who returned to estrus after the I.A. of a total of 27 vaconas after the protocol was made. In the cost-benefit analysis, the economic feasibility of the treatment was determined, since 63% of pregnant animals and 37% of animals that did not reach their pregnant status were obtained.El proyecto de investigación se lo realizó en la hacienda “LAS LOMAS” ubicada en la Provincia de Cotopaxi, Cantón Latacunga, en la Parroquia de Tanicuchi; el cual fue efectuado con el fin de evaluar un Protocolo de Inseminación Artificial a Tiempo Fijo “IATF”, utilizando como instrumentos principales los implantes intravaginales con progesterona “CIDR” aplicados en el día cero más la administración de 2 ml de benzoato de estradiol IM, al séptimo día se procedió a retirar los implantes intravaginales y se aplicaron 2 ml de Estrumate (F2&) que es una prostaglandina, al día ocho se aplicó 1ml de Benzoato de Estradiol B.E., el día nueve se retiró los dispositivos y se aplicaron 3ml de Gonadorelinas “Conceptal” 15 a 30 minutos previos a la I.A., por último se inseminó en el día 10 o se calcula entre 54 a 58 horas post retiro del implante, para lo cual se seleccionaron veinte y siete (27) vaconas con las mismas características en cuanto a condición corporal, alimentación y condiciones de manejo. El objetivo de la investigación fue evaluar los animales que se preñan, que regresan a celo natural y la ciclicidad de los mismos post protocolo IATF. Las vaconas son de raza Holstein, edades entre 15 y 18 meses y una condición ovárica de cuerpo lúteo para todas. Finalmente, en el día 45 posterior a la culminación del tratamiento, se realizó un chequeo ginecológico a todas las vaconas para conocer la presencia o ausencia de preñez. Se evaluaron las características de los animales que presentan celo, la preñez y el retorno del ciclo estral. Se verificó que dentro del grupo en tratamiento existieron como resultado 17 vaconas en estado de gestación, 10 que retornaron a celo después de realizada la I.A. de un total de 27 vaconas después de realizado el protocolo. En el análisis Costo-Beneficio se determinó la viabilidad económica del tratamiento ya que se obtuvo un 63% de animales gestantes y el 37% de animales no gestantes

    Parameters for the Grinding Process in Vertical Mills Using Optimization Methods

    Get PDF
    Vertical roller mills, VRMs, are widely used for grinding raw materials in factories engaged in the extraction and processing of minerals. Any machine used for grinding or crushing consumes around 30 to 40% of the energy of a factory. The loading pressure, table rotation speed, moisture content, outlet temperature and pressure rollers are variables that can be controlled to decrease the specific energy consumption Ecs. This paper poses an optimization problem in order to reduce the energy consumption of a VRM used to produce cement and to find the optimal parameters of the operating variables. Several packages are used to solve the nonlinear programming problem, obtaining very concise results, but the results provided by the Pyomo package are used. Comparing the result of the objective function with the energy consumption of a well-known cement company in Ecuador, it is concluded that the optimized parameters are able to reduce by 25% the energy consumption guaranteeing a minimum production of 2200 tons of cement per day, so the model is correctly validated

    On the Effectiveness of Hand Collection to Complement Baits When Studying Ant Vertical Stratification in Tropical Rainforests

    Choosing an appropriate sampling method to study ants is a key factor since distinct sampling methods can capture distinct ant fauna and, therefore, leading to bias in the interpretation and conclusion of the patterns observed. Despite it is well known that the ant fauna is vertically stratified, some of the sampling methods cannot be used throughout the whole vertical stratum (e.g., fogging and Winkler extractor). Here we compared the complementarity of hand collecting and baiting (with tuna or honey) in ant surveys focused on the stratification of the ant fauna in a tropical rainforest in Mexico. We found a total of 44 ant species, belonging to 17 genera and five subfamilies. The three sampling methods were clearly complementary at both the forest floor and canopy levels, even with as little as 10 minutes of search time for hand collecting. The ant species composition differed among sampling methods at both vertical strata. Hand collecting yielded higher ant species richness and more exclusive species than either bait at both vertical strata, but both tuna and honey baits also led to the detection of some (though fewer) exclusive ant species. The combination of hand collecting, tuna, and honey baits should thus be considered complementary tools for ant inventories, since using the two methods together yielded more complete inventories at both vertical strata. An additional advantage is that both methods can be used in both strata, ensuring that data in different vertical strata are comparable and allowing more reliable comparisons among these different habitats

    Facial implant gingival level and thickness changes following maxillary anterior immediate tooth replacement with scarf-connective tissue graft: A 4-13-year retrospective study

    ObjectiveA scarf-shaped connective tissue graft can be placed at the facial and proximal aspect of the peri-implant soft tissue zone during immediate implant placement and provisionalization (IIPP) procedures in the esthetic zone to optimize implant esthetics without the need of flap reflection. This retrospective study evaluated soft tissue stability after scarf-connective tissue graft (S-CTG) in conjunction with IIPP procedures in the esthetic zone. Materials and MethodsPatients who received IIPP with S-CTG with a minimum 1-year follow-up were evaluated. Mid-facial gingival level (MFGL) change and mid-facial gingival thickness (MFGT) change were measured and compared at the pre-op (T0), IIPP + S-CTG surgery (T1), follow up appointment with MFGT measurement (T2), and latest follow-up appointment (T3). Implant success rate and graft necrosis were also recorded. ResultsA total of 22 IIPP and S-CTG procedures in 20 patients were evaluated in the study. After a mean follow-up of 8.2 years (3.9-13.4) (T3), all implants remained osseointegrated (22/22 [100%]), with statistically insignificant mean midfacial gingival level change of -0.19 mm (-1.5 to 0.8). Statistically significant difference in midfacial gingival thickness (MFGT) was noted (2.5 mm [1.8-3.5 mm]) after a mean follow-up time (T2) of 2.3 years (1-8.6) when compared with MFGT at baseline (1.1 mm [0.6-1.3 mm]) (T1). Necrosis of S-CTG during initial healing phase was noted in 9% (2/22) of the sites. ConclusionsWithin the confines of this study, scarf-connective tissue graft at time of immediate implant placement and provisionalization can thicken the gingiva and maintain the gingival level at the critical soft tissue zone. Clinical SignificanceManaging the soft tissue zone is as important as that of the hard tissue zone for peri-implant esthetics. Connective tissue graft is one of the methods that can enhance the final esthetic outcomes. This retrospective study has demonstrated that Scarf-CTG technique is an effective treatment modality to maintain soft tissue stability
