This article presents the results of the control of a buck converter with a PID controller using the co-simulation tool between Multisim and LabVIEW. Both programs interacted together to couple the analog circuit with the digital controller simulating the responses as if it were in a real scenario. The results show that it was possible to improve the output of the buck converter with an FPGA PID controller that works in real time.

3D electrical resistivity tomography has become an important tool in the evaluation of the archaeological value of Hispanic sites in the tropics. This methodology was applied inside the open space (cloister) of La Compañía de Jesús convent, which is one of the most important ancient structures of the Panama Viejo Historic Monumental Complex. In this area, a set of apparent electrical resistivity values was measured along 22 parallel profiles 23.5 m long, separated 1.0 m. 3D inversion of these data resulted in a set of horizontal maps of calculated electrical resistivity values at different depths, showing important electrical anomalies associated with the stone column bases and the limits of the cloister.
三维电阻率层析成像已成为评估热带地区西班牙遗址考古价值的重要工具。这种方法应用于La Compañía de Jesús修道院的开放空间(回廊)，该修道院是巴拿马Viejo历史纪念性建筑群中最重要的古代建筑之一。在该区域，沿22条长23.5 m、间隔1.0 m的平行剖面测量了一组视电阻率值。对这些数据进行三维反演，得到了一组不同深度的计算电阻率值水平图，显示了与石柱基座和回廊边界相关的重要电异常。

Providing energy to areas isolated from the electricity grid through the use of a smart integrated renewable energy system (SIRES) is based on the Agenda 2030 for Sustainable Development, specifically Goal 7, according to the United Nations (UN). This study analyzes the process of identifying the appropriate size of a SIRES considering technical and economic factors (cost of energy-COE). An optimization integer linear programming model proposed was used, and a subsequent spatial-temporal analysis of the different variables was conducted. The model comprises locally available renewable energy resources, such as biomass, biogas, wind power, solar photovoltaic, and thermal power. Furthermore, it could be used to determine the energy potential of each of the isolated villages, identifying those areas in which the SIRES could be implemented as a sustainable and economical solution. The design simulates the cost of the initial investment and energy generation in the chosen village. The study also includes the study case in the region of Valparaiso, Chile. Different scenarios were used to optimize the available resources and minimize the COE generation.

The first formal regulations for assessment and seismic rehabilitation of structures started in 1980's, with the implementation of the results of developed research, and efforts conducted by organizations such as the Applied Technology Council (ATC), Federal Emergency Management Agency (FEMA), American Society of Civil Engineers (ASCE), among others; which have compiled different methodologies for evaluation and rational design of structures subjected to seismic loads. In our country, the Structural Design Code for the Republic of Panama, in its last version (REP-2014) incorporates for the first time design methodologies based on performance, as an alternative lateral force method; and refers to the document An Alternative Procedure for Seismic Analysis and Design of Tall Buildings located in the Los Angeles region. This article specifically presents the nonlinear static procedures for structural performance evaluation of buildings. Nonlinear modelling to generate the seismic capacity curve for a building (pushover curve) will also be described. Similarly, seismic demand characterization by inelastic acceleration spectra for different earthquake levels will be presented. Another important aspect to be studied is the global structural response of lateral displacements, as well as the local response in terms inelastic rotations of the elements. By applying this methodology the engineer can verify whether the structural response (i.e., exhibited damage) satisfies the acceptance criteria established by design codes.

Potato (Solanum tuberosum) is the fifth most important crop in the world, after sugarcane, corn, wheat and rice; In the potato an important content of alkaloids and glycoalkaloids has been introduced. The glycoalkaloids are biologically active compounds, which offer natural defense against plants against insects and fungi; However, these reports refer to human health and human health. In this logic, the influence of fertilization on the content of glycoalkaloids α-solanine and α-chaconine was evaluated, according to a completely randomized and random factorial design 4 x 3 where the independent variables are Potato genotypes (Parda Bilingüe, Pastusa Suprema, Roja Huila and Única) and levels of fertilization (1 = Corresponding to the recommendation given according to the analysis of the soils with respect to the fifth approximation of the ICA, 2 = corresponding to 50% of the requirements of nitrogen phosphorus and potassium for a production of 40 ton / Ha and 3 = corresponding to 75% of the requirements of nitrogen phosphorus and potassium for a production of 40 tons / Ha). The content of glycoalkaloids was determined by HPLC. As a result, it can be stated that not all potato genotypes are present in the glycoalkaloid content due to fertilization.

Nowadays a great amount of data related to health issues is stored, and each time the volume is increasing. In Panama, diabetes is a disease that causes a considerable number of deaths per year. This disease is the fifth cause of death in the country. Diabetes is one of the diseases with the greatest socio-sanitary impact, both due to the great importance it has, and also due to the large number of chronic complications that the patient has and in addition to its high mortality rate. Diabetes is a silent disease and every day in our country there are more people who suffer from it, it is unfortunate that many young people are developing this disease they do not know they have it. Using innovative technologies such as artificial intelligence (AI) applied to sensitive areas such as health is increasing every day. The new models based on machine learning currently, is growing, however in our countries there are few studies related to the subject. Therefore, this research aims to use various techniques of machine learning and determine how these models can help us to solve health problems.

Tuberculosis (TB) is a contagious disease and one of the main causes of mortality worldwide. This disease caused by the bacterium Mycobacterium tuberculosis and almost affects always the lungs. It transmitted from person to person by air and, although it is curable, if is not detected and treated in time, it can be fatal. To detect this disease, there are several types of methods, the largest used in the world being the smear microscopy. This is because this method characterized by being simple and quick to detect the presence of the bacillus by microscopic evaluation. This method consists of dyeing the tubercle bacilli using an appropriate technique. This may be possible because mycobacteria are acid-fast bacilli (BAAR), which means that they are able to capture fuchsine or auramine in their wall, and retain it even with the action of bleaches. The appropriate technique for this process is the coloring of Ziehl-Neelsen (ZN). The Pontifical Catholic University of Peru (PUCP) has a sample preparation prototype that makes use of the ZN staining method, which has worked, but requires a redesign to improve their performance. This paper, with the financing of the Vice-Rector for Research of the PUCP, deals on the equipment that performs the staining automatically for seven samples.

Throughout the literature and current practice in highways construction projects, Partnering has been known as an effective management technique to improve performance project metrics; moreover, for some US transportation agencies (DOT), it has contributed to a change in the business behavior. Some organizations have evolved partnering into different intensity levels and incorporated into alternative contracting methods (ACMs). However, there are scarce studies that validate the improvement on partnered project performance metrics. This paper describes the elements to define the partnering intensity regarding the project characteristics and partnering tools. This study hypothesizes that a higher partnering intensity, the better project outcomes concerning cost, time and claims. The paper bases this assertion on the analysis of cost and time growth and claim cost of 20 partnered highway construction projects located in seven transportation agencies within the United States grouped into two categories: partnering intensity and the type of contracting methods. A higher partnering intensity is applied to complex projects and large collaborative procurement practices. The paper highlights several contributions of partnering intensity to attain a better understanding of organizational matureness to achieve improved partnering management practices.
