The solution of Laplace's equation within a Classical Electrodynamics course is fundamental for the understanding of boundary problems in Electrostatics. In the present research work the analytical and numerical solution is obtained by the relaxation method, of a problem of infinite parallel plates, of the Laplace equation in Cartesian coordinates in an Euclidean space of two dimensions, specifically using the Python programming language, for its use in the teaching of Physics and its better phenomenological understanding. Likewise, the solutions obtained by both solution techniques are compared and discussed.

Presenta aplicaciones de optimización topológica para problemas de valor propio, como frecuencia natural o carga de pandeo linealizada utilizando elementos finitos-poligonales en dominios bidimensionales. En este trabajo se presentan algunos aplicaciones de optimización de topología para problemas de valores propios donde el objetivo principal es maximizar un valor propio especificado, como una frecuencia natural o una carga de pandeo linealizada utilizando elementos finitos poligonales en dominios bidimensionales arbitrarios. La idea es obtener la distribución óptima del material para maximizar la frecuencia natural fundamental (por ejemplo, para mantenerla alejada de una frecuencia de excitación externa o para maximizar la frecuencia más baja) o maximizar la carga crítica de pandeo (por ejemplo, para asegurar un mayor nivel de estabilidad de las estructuras) sometiendo a una r...

Remote sensing is the technology that has enabled us to obtain information about the Earth's surface without directly contacting it. For this reason, currently, the Bolivian state has considered a list of interesting applications of remote sensing in the country, including the following: biodiversity and environment monitoring, mining and geology, epidemiology, agriculture, water resources and land use planning. The use of satellite images has become a great tool for epidemiology because with this technological advance we can determine the environment in which transmission occurs, the distribution of the disease and its evolution over time. In that context, one of the important diseases related to public health in Bolivia is Chagas disease, also known as South American Trypanosomiasis. Chagas is caused by a blood-sucking bug or Vinchuca, which causes serious intestinal and heart long ter...

In outpatient consultations, physicians utilize tools to optimize time and enhance their clinical interviewing skills, as these interactions can be complex (e.g., new problems, chronic conditions, mental health issues). New problems can be addressed using the TOPIC model (Tasks Oriented to Outpatient Care Processes), which sets standardized tasks and processes to identify needs in this type of visit. This article describes this tool.

This article is studied the optimal control of distributed parameter systems applied to an environmental pollution problem. The model consists of a differential equation partial parabolic modeling of a pollutant transport in a fluid. The model is considered the speed with which the pollutant spreads in the environment and degradation that suffers the contaminant by the presence of a factor biological inhibitor, which breaks the contaminant at a rate that is not dependent on space and time.Using the method of Lagrange multipliers is possible to prove the existence solving the problem of control and obtaining optimality conditions for optimal control.

The integrative approach to care for patients demands training to evaluate frequent chronic problems in the outpatient clinic. Patients with hypertension, diabetes mellitus and asthma can be approach using models of evaluations such as the TOPIC that allows to order the evaluations in a structured sequence of four mayor tasks: processing of the information, development of an adequate physician-patient-family relationship and integrating information and learning for life. Processing information implies four sub-activities in which we evaluate patient´s expectations and concerns, severity and control of conditions, adherence and side effects of treatments focusing on damage to target organs and comorbidities. Applying this model can help physicians and their patients to be more efficient in managing chronic problems considering the short time available for ambulatory care.

“Background: Studies exploring long COVID condition (LCC) in low- and middle-income countries are scarce. Further characterization of LCC patients experiencing activity limitations and their associated healthcare use is needed. This study aimed to describe LCC patients’ characteristics, its impact on activities, and associated healthcare use in Latin America (LATAM). Participants: Individuals who (cared for someone or) had COVID-19 and could read, write, and comprehend Spanish and lived in a LATAM country were invited to complete a virtual survey. Sociodemographic characteristics, COVID-19 and LCC symptoms, activity limitations, and healthcare use. Results: Data from 2,466 people from 16 countries in LATAM were analyzed (females = 65.9%; mean age of 39.5 ± 53.3 years). 1,178 (48%) of the respondents had LCC symptoms (≥3 months). These were more likely to have COVID-19 earl...

One of the efficient techniques that is currently used in pavement engineering to improve the stress–strain response conditions of the pavement structure includes the stabilization of its structural layer components. There are several laying techniques that include the usage of stabilizing agents such as emulsified and foamed asphalt. In these technologies, the temperature of the environment is observed to play a critical role. This condition is often considered to be the main factor that encourages the usage of foamed asphalt for stabilization. Further, the aforementioned technique specifies that, at temperatures of approximately 10 °C or lower, the asphalt particles are not effectively inserted in the foamed granular material mastic; they are instead merged with other asphalt particles. This causes an agglomeration of coalesced asphalt, prevents adequate foaming, and hinders the pav...
