Polymers have become one of the most recognized materials in the industry, due to their good physical properties and the efficiency of their production process, in addition to the versatility and breadth of their fields of application in the aerospace, automotive, construction, textile and adhesive industries. In the case of cellulose acetate, it is used in a wide variety of everyday products such as photographic films, varnishes and cigarette filters, which makes it a factor that negatively affects the environment, since this material takes a long time to decompose and in the process contaminates the place where it is located with particles, on the other side are the agricultural residues that are manipulated in an inappropriate way, generating contamination in landfills and water sources, the following bibliometric analysis was carried out in order to provide a solution to the worrisome situation of this polymer contamination and the agricultural residues contamination, in order to encourage the development of studies focused on producing degradable materials. Therefore, this article presents a bibliometric analysis on the various alternatives to replace cellulose acetate, focusing on the collection methodology and comparison of studies with a tool known as HitsCite. The articles have been investigated by bibliometric, trend and cluster analysis in a sample of 361 articles. The research has been carried out in one of the most recognized databases such as web of science and has allowed to identify the main trends and dynamics of the scientific literature. This in order to mitigate the environmental problems that are present in our environment and being a starting point to support monetary studies that implement environmentally friendly materials, being a topic that can create a positive and innovating impact in the industries commercial sectors.

Dosage is a technique to modify and improve the conditions of the soil-cement that comply with the conditions of the "Instituto Nacional de Vías" standard and in the same way, is economic to be implemented in different types of clay. The clay was classified depending on its plasticity (high plasticity and low plasticity) and the behavior at loads; making laboratory tests of modified proctor, compaction and CBR% for the clays with 4% of soil cement; at the same time, the results of CBR% of soil cement of 4% with natural soils, of 6% of cement and 1 were compared. In this way, was made a proposal of the elaboration of each type of soil-cement with its respective percentage, concluding that the clay of high plasticity can be used for subgrade and the one of low plasticity has a weak bearing capacity.

Urban transport is an indispensable component for the development of cities, however, the massive use of motorized modes of transport with polluting technologies has generated the non-sustainability of the sector. Colombian cities are no strangers to this problem and as an improvement strategy, the testing and implementation of electric transport technologies is considered as an opportunity for modernization, efficient use of energy, reduction of emissions and energy diversification taking advantage of the energy resources available in Colombia. In Bogotá, the taxi fleet, due to its high energy demand and responsibility in polluting emissions, is a segment where electric vehicles can offer benefits to the operator, the citizen and the city. A description of Bogota's taxi fleet, the presentation of electric vehicle technology and a comparison between a gasoline vehicle and an equivalent electric vehicle in regular operation are presented, as well as some results from the pilot's early years. The technology has demonstrated reliability and efficiency, benefits to drivers and significant savings in greenhouse gases, but requires new incentives for massification.

Rojas Suárez, Jhan Piero | 2019-11-29

The clay is used in the area of constructions, ceramics and industrial applications: insecticides, pharmaceutical industry, cosmetics and painting, for its physical and chemical properties that are suitable for different civil projects (roads, public services network, constructions); the dosage is a technique to modify and improve the conditions of the soil-cement in reference to the resistance, conditions of insolubility, impermeability, durability and appearance. In this study, high plasticity clay was evaluated through different laboratory tests (humidity test, soil liquid limit, plasticity index, granulometric analysis, California Bearing Ratio) for three samples and specifying the methodology used in each step, with the objective of knowing its structure and functioning in rural roads in combination with soil-cement, looking for a more profitable and lasting option in this sector, in order to benefit the people surrounding these sectors, improving the income of the sector and seeking to mitigate the environmental impact.

In this project, a descriptive research was carried out in order to analyze, evaluate and detail the behavior of buildings between 4 and 18 floors of residential use in the City of San José de Cúcuta, Colombia, at the moment they are subjected to forces produced by earthquakes. For this purpose, a sample of 40 buildings framed in the above-mentioned characteristics was used by means of the SAP 2000 software. The seismic analysis of each building was made and the displacements of these were obtained when they are submitted before an earthquake. With this information, it was possible to calculate the drifts and evaluate them based on the requirements that determine the stiffness conditions present in the buildings. Finally, a document was drawn up identifying those buildings that are susceptible to significant damage in the event of a seismic movement and recommendations, due to the fact that they represent a social risk.

Rojas Suárez, Jhan Piero | 2019-09-30

The automobile is the main means of transportation in most cities of the world, however, its excessive use has generated several environmental and social problems, one of them is the lack of control over parking on public roads, affecting vehicle traffic, disturbing the image of the city, increasing the rate of accidents and causing negative effects on the mood of drivers and pedestrians. There are different alternatives to reduce these indicators, highlighting the effectiveness of the implementation of parking meter systems, which seek to regulate parking on public roads through a fee and a time limit. This article demonstrates the design, feasibility and impact (economic, social and environmental) of an implementation of the parking meter system in the center of the city of San José de Cúcuta, Colombia, with data from the Secretariat of Transit of the metropolitan area of the city of San José de Cúcuta, Colombia and the national institute of roads, achieving a solution to the problem of traffic congestion in the city and also contributing to create citizen culture among its inhabitants.

The need to improve people's living conditions starts from the reality of the durability of rural road constructions, which have a short useful life and have a negative impact on the inhabitants of these regions. This project aims to improve access to rural areas, rural economic development and thus improve the quality of life of people in the sector; taking into account that at the moment of building a rural road, has a better resistance and durability in time, this was done by analyzing the properties of the clay mixture of low plasticity in the dosage of soil-cement that were tested by tests to determine the liquid limit of soils, determination of the plastic limit, plasticity index, moisture test, classification of soil by sieving, granulometric analysis, unit weight-humidity relations in soils, soil support relationship in the laboratory; in order to find the best dosage that provides greater strength, long-term durability and risk reduction. The results indicate that this type of clay requires an improvement with cement, due to its bearing capacity of 2% and 4%, which gives it a very poor quality to be used in the construction of rural roads.
