Objective: To know the current state of research on the evaluation of the Carbon Footprint (CF) of coffee and its value chain. Methodology: A systematized review of literature from international bibliographic databases was conducted, identifying five aspects; 1) place of assessment, 2) scope of the assessment, 3) methodology used, 4) result of the CF, and 5) functional unit of measurement considered. Results: Sixteen articles from 16 countries were reviewed, evaluating different scopes of the coffee production chain. Six different methodologies were applied, including international standards and specialized software. The calculated CF ranges from 0.12 kg/CO2eq to 14.61 kg/CO2eq depending on the scope of the research in the coffee production chain. Limitations: Scarce collection of publications obtained in the systematized search process. Conclusions: There is a need to increase research on the subject in small-scale production areas, since most of the methodologies and applications have focused on areas where the grain production and technification are concentrated, leaving aside other production areas that require attention with respect to their production processes.

Contextualization: Life Cycle Assessment [LCA] is a useful tool for assessing the potential environmental impacts of a product. Due to the growing interest in climate change mitigation and on the implementation of sustainable practices of production, it is interesting to study the environmental profile of essential oil products and similar products to identi fy shortcomings in current technologies and possibilities for improvement. Knowledge gap: the existing literature about the essential oil production lines is quite limited, although its production is similar to other products derived from agricultural materials, for which the bibliography is more extensive. Purpose: to review the methodological aspects addressed in research related to life cycle analysis of agricultural feedstocks, with focus on essential oil production. The study was focused on those studies that employed a non-conventional approach describing the reasons for their methodological choices. Methodology: research papers from the last 12 years, which analysed the life cycle of agro-industrial products, were searched and filtered. The aspects reviewed included the scope, the impact categories, the functional unit, the sources of information, the allocation methods, and the tools (software and database) used. Results and conclusions: using the previous aspects, it was possible to identify methodological trends such as the general use of a cradle-to-gate approach, the use of SimaPro software coupled with the Ecoinvent database, and mass and economic allocation methods. Regarding the last method, it was found that the economic allocation is more accentuated in the case of essential oils, due to the significant differences that exist between their mass and economic value.

This article reviewes the prediction of carbonation in concrete with recycled aggregate in all stages and aspects related to sustainability. Concrete carbonation has two sides. In reinforced concrete, the research approach aims to prevent the advance of the carbonation depth so that the pH drop does not lead to reinforcement corrosion. The parameter of this approach is the carbonation coefficient. In non-reinforced concrete, priority is given to the higher absorption and sequestration of carbon dioxide to reduce global warming. Thus, obtaining the parameter degree of carbonation is necessary. In the case of recycled concrete, these two parameters become more critical due to its particular pore structure. The correlation between natural or accelerated carbonation and other durability properties is also described. Different predictive carbonation models are mentioned, including those based on artificial intelligence, and the service life calculation is introduced. The literature review shows a growing trend in measuring transport properties to use them within predictive modeling. This modeling is based on the fact that these predictions have higher reliability than those derived from mechanical or fresh-state properties. As for performance verification, it is required to compare model results with experimental carbonation results under realistic environmental conditions. Checking a possible dependence with experimentally determined recycled aggregate characteristics is also recommended. Finally, some considerations and actions are proposed to analyze the sustainable aspects of the material life cycle effectively. [ABSTRACT FROM AUTHOR]

Introduction: The life cycle analysis (LCA) is intended to be a quantitative tool to support decision making. The evaluation of uncertainties allows evaluating the strengths and weaknesses of the estimates made. Monte Carlo Analysis is one of the most widely used methods to propagate uncertainty results. Objective: To know the uncertainty associated with the data and the models used to assess the impact on each category considered, according to the LCA methodology, for the management of Municipal Solid Waste in the Xalatlaco municipality, Mexico. Materials and Methods: In this study, an uncertainty analysis is carried out, using the Monte Carlo method, to evaluate the propagation of data uncertainty in the results of each impact category considered in the study and the comparison of the scenarios, to select the most convenient. Results and Discussion: The results show that the inventory data influence the results of each of the categories; however, the coefficients of variation are less than 25%. The comparison of the Base Scenario with the best option (Scenario 3), allows us to identify that in all the categories the results present lower impacts with respect to the Base Scenario except for ozone layer depletion. Conclusions: The importance of the uncertainty analysis in the Life Cycle Analysis as support in decision making is verified. The implementation of Scenario 3 is feasible. [ABSTRACT FROM AUTHOR]

Citrus black spot (CBS), with Phyllosticta citricarpa (McAlpine) van der Aa as the causal agent, is a disease that affects Citrus spp. It produces considerable economic losses due to the staining and premature fall of the fruits, and the limitations for their export to countries where the pathogen is considered a quarantine pest. Recent studies provided novel results on this subject. Among them, the description of new species of the genus Phyllosticta associated with citrus stands out, and it hinders the diagnosis of P. citricarpa. In addition, an atypical life cycle was detected for this fungus in some citrus regions, while the development of fungal-resistance in populations of this pathogen and effective fungicides and biological control agents for its management have been reported. Taking these aspects into consideration, this work offers a current overview of CBS in the world and in Cuba, attending to the damage it causes, its economic impact, the characteristics of the causal agent that influence epidemiology and its management, as well as its main challenges and future prospects.

The main objective of the present study is to assess the relationship between information and communication technologies (ICT) and the life cycle of knowledge management in the initiative "Reconstruction of the Social Fabric in Post-Conflict Zones in Colombia." A survey (Likert scale) is designed and sent to 120 researchers, obtaining data from 74 respondents. Descriptive and correlational (Spearman) analyses are performed. The results show that ICTs correlate moderately and significantly with the initiative's life cycle of knowledge management. They also show that it is feasible to advance in the consolidation of a knowledgeable society, but at the same time, ICTs generate new challenges and goals for communities involved in the Colombian peace process. It is concluded that ICTs have a positive and significant impact on knowledge management. [ABSTRACT FROM AUTHOR]

The relationships go through different situations that can generate instability and upsets or conflicts between the members of the couple, which impact on it, favoring dissatisfaction, frustration or even the end of the relationship, greatly affecting the health and well-being of the person. Based on this, the objective of this study was to know the relationship among the conflict reasons and importance with health and satisfaction with the relationship. To this end, we worked with 240 people (50% women and 50% men), aged between 18 and 75 years who were in one of the four stages of the couple's cycle: development, maintenance with small children, maintenance with older children and dissolution.

Wind energy corresponds to an alternative energy due to the production of mechanical or electrical energy using the kinetic energy of the wind, thus replacing some of the fossil fuels that are commonly used as energy sources. Furthermore, this study will make it possible to determine its potentials. It should be noted that wind energy is implemented in parks, located in rural areas with little economic development and represent a source of income for municipalities. Based on the foregoing, this study revolves around the potential supply of this type of energy in the Department of Quindío, where the periods of the year will be evaluated, as well as the places where the greatest potential is presented.

Introduction: Hamadryas feronia feronia, which mimics the bark of trees and often makes attention-grabbing sounds when flying, has good potential for bio-business (export, handicrafts and tourist breeding centers). However, its biological aspects are still unknown, which hinder its captive breeding. Objectives: To determine the biological aspects of feeding, oviposition behavior, life cycle and natural enemies of Hamadryas feronia feronia L. in San Rafael-Indiana, Loreto, Peru. Methods: Sampling was conducted from January 2018 to December 2019 in the community of San Rafael, Amazon River. Adults were observed during the day, their food plants, oviposition behavior, biological cycle and natural enemies were recorded. The life cycle was evaluated in the laboratory, using 20 eggs recently deposited on the leaves of their host plant. Results: The larvae of H. feronia feronia feed on the leaves of Dalechampia juruana and the adults feed on the bark sap of Cedrela odorata, Spondias mombin, Uncaria guianensis and the fermented fruits of Syzygium malaccense and Pouteria caimito. Adults fly on sunny days, males emit a loud sound when flying. Females prior to oviposition flit irregularly around their host plant between 8.00 and 14.00 h and deposit their eggs on the upper and underside of leaves in isolation, most frequently on the underside. The duration of the cycle from egg to adult was 28.24 days. The average egg period was 3.75 ± 0.40 days. The larvae passed through five larval instars: the first instar 3.21 ± 1.03 days, the second 2.78 ± 0.73 days, the third 2.67 ± 0.77 days, the fourth 3.22 ± 0.81 days, and the fifth 4.61 ± 0.70 days. The prepupal period lasted 1.33 ± 0.49 days and the pupal period 6.67 ± 0.80 days; the adults hatched between 10:00 to 11:00 h. Adult males lived on average 31.80 ± 3.29 days, the female 42.00 ± 2.14 days and their eggs were parasitized by a microhymenopteran (Scelionidae). Conclusions: This study allowed to know the biological aspects of H. feronia feronia identifying its food plants of both larvae and adults, its oviposition behavior, as well as it has been determined that it has a relatively short biological cycle with a period of less than one month and its eggs are consumed by a small Hymenoptera that can hinder its production. This work provides necessary information to develop the breeding of H. feronia feronia, oriented to its conservation, environmental education and biotrade (tourism and handicrafts) in the Peruvian Amazon.

The life of Family Businesses is largely limited to the generational transition (on average 30% of these survive the second generation, 15% of these to a third, and 1% to the fourth). Objective: to analyze success and failure factors in successions from the literature. Method: to developed said analysis from a descriptive approach. The document review process completed the following stages: definition of the objective, bibliographic search, consultation of databases, establishment of search strategy and selection criteria, organization of information, and writing. Results and conclusions: the succession problem starts from the conflict of interests between the family business systems (company, family, and property), arising situations such as: informality, loose discipline, assumptions of permanence, nepotism, grasp, among others. Finally, a succession plan was developed considering the factors that influence the process. [ABSTRACT FROM AUTHOR]

El nematodo del quiste de la zanahoria Heterodera carotae es un patógeno importante en Daucus carota. Para que las medidas de control sean efectivas, el conocimiento de la dinámica poblacional del nematodo a través del tiempo es indispensable. El presente trabajo, evaluó la dinámica poblacional de H. carotae en cultivo de zanahoria, durante 10 meses bajo condiciones de invernadero. En junio del 2017, se colocaron en invernadero 90 macetas (3 L volumen): 60 fueron llenadas con suelo naturalmente infestado con el nematodo (1200 J2/maceta) y las 30 restantes se utilizaron como controles (sin nematodos). En cada maceta, se sembraron 10 semillas de zanahoria. Después de la germinación, las macetas fueron muestreadas destructivamente cada 15 y 30 días (n=3). Las raíces de cada maceta fueron pesadas y posteriormente teñidas. Los quistes y J2 se extrajeron del suelo. Las poblaciones de J2 tanto en suelo como raíz, se comportaron de manera similar. En suelo, se observaron tres picos de J2 a los 105, 150 y 195 días con 735, 882 y 967 J2/200 cm3 de suelo respectivamente. Se calculó un factor de reproducción de 1.6 y se observaron cinco generaciones del nematodo. H. carotae causó una pérdida promedio en rendimiento de 70.8% durante el experimento. Los resultados pueden ser usados para desarrollar herramientas en la toma de decisiones para optimizar el momento de implementación de medidas de manejo. [ABSTRACT FROM AUTHOR]

It is proposed the reuse of plastic in concrete blocks in replacement of fine aggregates. The technical, economic and environmental behavior of the proposal is analyzed, through mechanical tests, comparison of market prices and calculation of carbon footprint. Technically it was found that concrete specimens with 10% PET replacement have mechanical properties in accordance with Chilean regulation for no-structural blocks, which would allow the construction on non-structural walls. Economic analysis shows that concrete blocks is highly competitive compared to the products already on the Chilean market. Finally, the carbon footprint calculation on life cycle shows a decrease in the extraction stage of raw materials. [ABSTRACT FROM AUTHOR]

Objective. The composition of the homes of Bogota at different times of their life cycle is analyzed seeking to identify the support systems underlying those practices and the differences between the distinct groups according to the educational level of the head of the family. Methodology. Using the census data of 2005, homes are rebuilt and their composition is analyzed following a demographic approach. Results and conclusion. Differences in the types and compositions of the homes are found, which show socioeconomic contrasts. For all the groups studied, the rapprochement increases with the passage of the home life cycle and it concentrates on the moments that require more material support, which they solve in different ways: among the most educated, the coexistence with parents and maids stands out, while in the less educated there is a greater coexistence with grandchildren and sonsin- law who account for "nested" homes.

In this study, the environmental impacts associated with the life cycle of 1 m³ of drinking water in Pereira, Colombia were characterized. Four scenarios were analyzed: a baseline scenario and three hypothetical environmental scenarios. The life cycle was described, the inventory of matter and energy flows was made, and the environmental impacts of the midpoint and endpoint of the baseline scenario were established using the Impact 2002+ method, the environmental impacts of three hypothetical scenarios were defined also. The results determined that the processes related to the production of drinking water generated most of the negative impacts of the cycle (75-100 %) in 12 of the 15 categories of midpoint in the baseline scenario. Likewise, in this scenario, drinking water contributed 56 % of the endpoint impact. On the other hand, promoting a 20 % reduction in water consumption along with the treatment of wastewater would be the best future scenario, both to reduce mid-point impacts and to reduce end-point impacts.

En este artículo evaluamos las posibles soluciones ambientales sustentables a la problemática de los residuos de madera (biomasa residual), generados en los aserraderos y ebanisterías de los municipios de Quibdó y Riosucio en el departamento del Chocó. La evaluación la hicimos para tres usos: generación de energía alternativa, materiales aglomerados y fabricación de pélets de madera. Identificamos 109 empresas en los dos municipios (95 en Quibdó y 14 en Riosucio), que generan 723,15 ton/año de residuos biomásicos en Quibdó y 591,42 ton/año de residuos en Riosucio. Caracterizamos tres muestras de las especies forestales más utilizadas (Lechero, Guamillo y Jigua), y una cuarta muestra compuesta por una mezcla de estas especies, ya que las empresas no realizan separación en sus procesos de transformación. Las muestras presentaron poderes caloríficos de 13.013 kJ/kg, 15.334 kJ/kg, 13.452 kJ/kg y 15.345 kJ/kg respectivamente, siendo la mezcla la de mejor poder calorífico para propósitos de generación de energía. Como mecanismo de selección de alternativas hicimos el Análisis de Ciclo de Vida (ACV) con el software OpenLCA 1.6 y los datos de Ecoinvent 3.3 (indicadores de impacto del IPCC 2013), a partir de los cuales estimamos que la elaboración de los pélets genera 298,94 kg CO2-eq GWP 20? y 279,41 kg CO2-eq GWP 100, mientras que el aprovechamiento energético de estos residuos genera 572,92 kg CO2-eq GWP 20? y 559,35 kg CO2-eq GWP 100. La elaboración de los aglomerados no la consideramos viable debido a la cantidad de procesos requeridos en su producción, además del costo de la maquinaria y de las condiciones climáticas de la región (humedad y precipitación) que deterioran el producto. This research evaluated the possible sustainable environmental solutions to the problem of wood residues (residual biomass) generated in sawmills and joinery of the municipalities of Quibdó and Riosucio in the department of Chocó. We evaluated three uses: generation of alternative energy, agglomerated materials and manufacture of wood pellets. We identified 109 companies in the two municipalities (95 in Quibdó and 14 in Riosucio), which generate 723,15 tons / year of biomass waste in Quibdó and 591,42 tons / year of waste in Riosucio. We characterized three samples of the most used forest species (Lechero, Guamillo, and Jigua), and a fourth sample composed of a mixture of these species, since the companies do not perform separation in their transformation processes. The samples presented calorific values of 13.013 kJ/kg, 15.334 kJ/kg, 13.452 kJ/kg and 15.345 kJ/kg / kg respectively, being the mixture the one with the best calorific value for purposes of power generation. As a mechanism for selection of alternatives, we developed the Life Cycle Analysis (LCA) with the OpenLCA 1.6 software, using data from Ecoinvent 3.3 (impact indicators of IPCC 2013). The analysis allowed us to determine that only the production of pellets generate 298,94 kg CO2-eq GWP 20a and 279,41 kg CO2-eq GWP 100, and the energy use of this waste generates 572,92 kg CO2-eq GWP 20a and 559,35 kg CO2-eq GWP. We did not consider agglomerates as a viable option, due to the amount of processes required for their elaboration, the cost of machinery required and the climatic conditions of the region (humidity and precipitation) that may easily deteriorate the product.

Due to the need to evaluate the sustainability of distributed generation in Cuba, this work aims to: evaluate the environmental impact and the exergy efficiency of the distributed generation in the Fuel Power Plant Sancti Spíritus. The Life Cycle Analysis methodology was applied to two variants and an exergy balance to the generation area. In engine iswhere the greatest transformation of energy occurs. In exhaust gases of the first variant, 986,32 kW are expelled to atmosphere, which represents 34,80% of the total energy entering at engine, and in the second 1168,57 kW, that represents 40.39%. Likewise, in first variant, the use of energy in electricitygeneration is 35.29% of fuel oil total energy and in the second is 34.56%, demonstrating that the first variant is more energy efficient. The generation process has the greatest responsibility over the impacts generated by the plant and the impactcategory which most impact is the impact on human health. In generation process, the exergy efficiency of the product (1 MWh) in the first variant is 17.60% of the total exergy supplied, and the second variant is 17.37%. The exergy efficiency in the first variant was 67.36% and in the second variant 62.42%. In use of exhaust gases, it was 10.91% for the first variant and 6.06% for the second. [ABSTRACT FROM AUTHOR]

Research groups have been traditionally described as functional units that primarily focus on scientific research processes and academic production. However, these definitions do not generally consider the team and individual dynamics that take place during their life cycle. This study aims to propose a theory of the life cycle of research groups, identify the motivational aspects of its members, and (based on that) provide elements to create a new definition. For this purpose, a qualitative study analyzed information collected in 2014 and 2015 from a self-evaluation process of the group Psicología y Salud in which teachers and research professionals participated. The process applied information collection techniques such as surveys with open questions, focus groups and a qualitative interview. Said strategies enabled to obtain significant data that were later analyzed and categorized based on elements of the Grounded Theory. Three types of motivations to join the group were identified and a life cycle model was proposed. Finally, we suggest a comprehensive definition that recognizes research groups as human and social spaces that transcend scientific productivity. These results can provide institutions and said groups with tools to develop comprehensive policies and strategies focused on human talent in research and aimed at knowledge management.

The biology and life table of two populations of Chloridea virescens F. were evaluated under laboratory conditions (T= 24.02 ± 0.24°C; HR= 82.52 ± 0.72%). Both populations differed in the morphological characteristic of the last instar larvae and the organ of the plant of tobacco from which they were collected. They were separated into two groups: Group A, larvae from the leaves of the plant head and Group B, larvae from the capsules. From these larvae, adults were obtained that mated and after the oviposition initiated, a cohort of recently emerged larvae of both groups was selected. They were disposed on leaves of tobacco to continue their development until adult death. In each group, the number of eggs per laying, the duration of the each development phase, and the main population parameters were recorded. The biological parameters showed significant differences in the larval and pupal duration and the life cycle that favored the specimens of the Group A, as in the population parameters. The results indicated that these parameters in the Group B population were affected by the change of food; however, a high reproductive capacity was evident in both groups when the specimens fed on leaves of the plant head, and the potentiality of both populations as pest of this crop was confirmed.

Background: Considering the uncertainty of Mexican families about their future income and grand expectations on financial inclusion policies in the country, consumption studies continue to be important. Studying household savings and credit patterns is a fundamental key to financial development. Methods: This paper uses a synthetic panel to provide a semi-parametric estimation of savings and debt patterns over life cycle. Result: It shows that the beginning of family life mainly depends on credit, while at the end, there is a high monetary saving profile, sustained and different from the reduction predicted by the life cycle model. Human capital and income explain most of differences between families' financial patterns. Conclusions: Results show persistence of inequalities in the financing process; financial literacy and saving incentives should be main goals for the country's inclusion strategy.
