In Panama, in the last 20 years, investment in sanitation has increased both at the State and private levels, driven by the generation of discharge regulations. Although it is true that recovery of the bodies of receiving water is being achieved due to these investments, little has been done with the byproducts of this sanitation, especially the generation of organic sludge or wastewater biosolids. For this reason, our research focused on the study of biochemical methane potential (BPM), through anaerobic digestion tests using the Oxitop system. These results of our research are the results of the evaluation of biosolids from wastewater treatment plants of various economic activities. The findings of the studies of digestivity show that there is a variation in BPM according to economic activity. The maximum BPM values were obtained for municipal biosolids; whose value was 103 mL CH4/g SV. These results are consistent with the contents of similar studies. However, it is required to deepen this subject, with the aim of improving the yields of BPM from wastewater biosolids, by coding, complementing other organic substrates.
在巴拿马，在过去20年里，在排放法规的推动下，国家和私营部门对卫生设施的投资都有所增加。虽然这些投资确实实现了接收水体的回收，但这种卫生设施的副产品，特别是有机污泥或废水生物固体的产生，几乎没有得到处理。因此，我们的研究重点是通过Oxitop系统的厌氧消化测试来研究生化甲烷势(BPM)。这些研究结果是对各种经济活动废水处理厂的生物固体进行评价的结果。消化率的研究结果表明，根据经济活动，BPM存在变化。城市生物固体的BPM值最大;其值为103 mL CH4/g SV。这些结果与类似研究的内容一致。然而，需要深化这一主题，以提高废水生物固体中BPM的产量为目的，通过编码，补充其他有机基质。

The reuse of discarded tires can reduce the great environmental problem associated with their inadequate final disposal. One way, is its addition in compacted soils that can provide solutions to the mechanical-geotechnical problems related to low shear strength. This study presents the behavior of a silty sand reinforced with shredded rubber of discarded tires, through an experimental study. Physical characterization tests, Standard Proctor, direct shear test and consolidated undrained triaxial test (CU) were carried out in order to establish patterns of mechanical-geotechnical behavior that define the influence of the addition of rubber in this soil. The Direct shear and triaxial tests were performed on compacted soil samples at their maximum dry density and optimum moisture. The specimens tested were made with rubber contents of 0%, 5%, 10%, 15% and 20%, in relation to the dry weight of the soil. On the other hand, the triaxial test was carried out with specimens that content 0% and 5% shredded rubber. The results showed that the shear strength increased in samples with 5%, 10% and 15% of rubber with respect to soil. This addition of rubber is more effective for confinement tensions greater than 50 kPa and less than 300 kPa. It was concluded that the addition of 5% rubber is the one that provides higher shear strength.

This paper engages readers with innovative research methods to learn about popular places in the city. Using locational data of Social Media platforms, including Twitter, Facebook, and Instagram, along with participatory field visits and combining insights from architecture and urban design literature, this study reveals popular socio-spatial clusters in the City of Chicago. Locational data of photographs were visualized by using Geographic Information Systems and helped in producing heat maps that showed the spatial distribution of posted photographs. Geo-intensity of photographs illustrated areas that are most popular visited in the city. The study's results indicate that the city's skyscrapers along open spaces are major elements of image formation. Findings also elucidate that Social Media plays an important role in promoting places; and thereby, sustaining a greater interest and stream of visitors. Consequently, planners should tap into public's digital engagement in city places to improve tourism and economy [1].

The behavior of five types of welded connections of composite columns rcft (rectangular tube filled with concrete) and type i steel beams used in ecuador, all made with the same materials, dimensions and construction processes, has been compared, modifying the form of the connection, this being the only variable to investigate. By performing experimental cyclic tests following the loading protocol defined by ansi / aisc 341-16, 2016, it was possible to determine the real behavior of these connections, obtain the necessary hysteresis curves, define which test piece of the tested ones presents a better behavior and energy dissipation capacity, as well as analytical models of the tested specimens, were made using finite element methods for comparison.

The optical properties of metallic nanoparticles are widely studied in nanooptics due to the multiple applications that can be developed. In this work we explore, by means of numerical simulations, the optical properties of metallic nanoparticles in order to attenuate the infrared radiation in a window. The simulations were carried out by solving the full Maxwell equations using the boundary element method (BEM). Gold, silver and aluminum nanorods were simulated, as well as silver nanotriangles. The simulation results and numerical calculations show a high transmittance in the visible range and a strong attenuation at wavelengths between 700 nm and 1575 nm (which corresponds to most of the infrared radiation coming from the sun) for the case of gold and silver nanorods and for silver nanotriangles. Our results provide useful details for the design of infrared-blocking windows.

Adobe is one of the most widely used materials for housing construction worldwide, because it is low cost and easy to prepare. However, one of its main disadvantages is its low resistance to compression and bending. The addition of natural fibers in the preparation of adobe has been investigated during the last years in order to improve its resistance. Cabuya fiber was added to improve the properties of the adobe units with straw in different percentages. With the fiber addition percentage of 1.75%, the compression resistance improves by 40% and the resistance to bending by 12%.

This work compares in a comparative way some advances in the promotion and management of Social Innovation adopted by four Latin American countries, including Panama, in order to generate more knowledge to promote the strengthening and design of new public policies in this ambit. Panama is in the incipient stage of Social Innovation management, compared to the other three countries analyzed: Colombia, Costa Rica and Chile. Among the structural elements addressed are: regulations, the degree of institutionality, mechanisms and incentives to promote social innovation projects and good institutionalized practices. Since 2014, Panama shows its interest and advances in the subject, in the academic and university academic sectors, which can take advantage of social innovation to obtain a greater impact in the country and promote a more inclusive social development. Colombia began efforts to promote Social Innovation in 2007, Chile and Costa Rica in 2014, as well as Panama. These three countries have a higher level of progress in the elements analyzed in their Social Innovation ecosystems than Panama, however, they do not have enough mechanisms to clearly identify the failures that prevent the strengthening of the culture of social innovation and, therefore, the establishment of much more effective public policies.

With the purpose of giving recommendations about building construction techniques in Panama to reduce the energy consumption, this article presents the results obtained from thermal dynamic simulations carried out for a generic building inspired on the building structure implemented in the Technological University of Panama Campus. This before by considering its geographical location, meteorological data, and composition of walls, floors, ceilings and windows. This simulation aims to study the thermal behavior of the building depending merely on its envelope features, specifically, on the variation of "window to wall" ratio (WWR) and on the addition of internal and external insulation layers on the external walls. Results showed that one of the most relevant features of the envelope is the WWR, which improved the indoor conditions significantly if minimized. However, adding insulation layer does not improve the building indoor conditions.

During 2017 and 2018, the Precalculus course at the Technological University of Panama was offered via an intelligent tutoring system (ITS). Analysis of the results show that student interaction with the ITS learning modules contributes to the levelling of knowledge and to improved performance in mathematics. As a by-product of this implementation, a proposal called "Remedial Action Program" (Spanish acronym, PAR), is presented in this article, the purpose of which is to take advantage of STI's to level students' mathematical knowledge, thereby improving their chances to be admitted to, and retained in, the UTP. This proposal is structured around three programs for students with different mathematics profiles.
