Andalusian Organic Farming Plans (2002–2016): Themes, Approaches and Values
Authors: Jiménez-Díaz José-Francisco , Collado-Campaña Francisco
Published: March 2021

Organic farming in the Spanish region of Andalusia has acquired great socio-economic importance over the past decades. The purpose of this article is to study the themes, approaches, and socio-political values pertaining to ecological agriculture addressed in the Andalusian plans for organic farming (2002–2016). The contents of these plans have not been systematically studied before. From a descriptive and qualitative perspective, the authors present and classify the main themes addressed in those plans and show the socio-political approaches and values that underpin the plans. A thematic and semantic content analysis methodology is applied to the plans and sections addressing various objectives, measures, and actions. A theoretical-qualitative sampling is developed, and 109 keywords are selected for content analysis. This analysis allows us to detect numerous themes pertaining to ecological agriculture and to classify them into six semantic fields linked to various approaches and values promoted by the Andalusian autonomous administration. Therefore, this research focuses on changing perspectives of organic farming developed by the administration and the agents involved in the plans. The authors conclude that the diverse actors have prioritized a productivist–technocratic approach to ecological agriculture, to the detriment of an approach centered on sustainable and agroecological local communities.
Multistage Chemical Recycling of Polyurethanes and Dicarbamates: A Glycolysis–Hydrolysis Demonstration
Authors: Zahedifar Pegah , Pazdur Lukasz , Vande Velde Christophe M. L. , Billen Pieter
Published: March 2021

The use of polyurethanes and, therefore, the quantity of its scrap are increasing. Considering the thermoset characteristic of most polyurethanes, the most circular recycling method is by means of chemical depolymerization, for which glycolysis is finding its way into the industry. The main goal of polyurethane glycolysis is to recover the polyols used, but only limited attempts were made toward recovering the aromatic dicarbamate residues and derivates from the used isocyanates. By the split-phase glycolysis method, the recovered polyols form a top-layer phase and the bottom layer contain transreacted carbamates, excess glycol, amines, urea, and other side products. The hydrolysis of carbamates results in amines and CO2 as the main products. Consequently, the carbamates in the bottom layer of polyurethane split-phase glycolysis can also be hydrolyzed in a separate process, generating amines, which can serve as feedstock for isocyanate production to complete the polyurethane material cycle. In this paper, the full recycling of polyurethanes is reviewed and experimentally studied. As a matter of demonstration, combined glycolysis and hydrolysis led to an amine production yield of about 30% for model systems. With this result, we show the high potential for further research by future optimization of reaction conditions and catalysis.

Published: March 2021

During China’s rapid economic development and urbanization, numerous cases of urban malodorous black river (MBR) have occurred. MBR refers to a polluted urban river that smells bad, is almost black in color, has no aquatic plants or animals, and that consequently causes many social and environmental problems. The Chinese government has sought public participation during the whole process of MBR treatment as part of a comprehensive action plan to improve residents’ satisfaction with their environment. To investigate the influencing factors of public participation and satisfaction, a questionnaire survey was conducted among residential communities close to an MBR. SPSS 22.0 was employed to conduct an analysis of the collected data, using factor analysis, correlation analysis, and linear regression analysis. The results indicate that there is a direct relationship between public satisfaction and the factors of government treatment, public perception and public participation behaviors, such as engagement behavior, supervision behavior, health influence, and compensation measures.

Authors: Blanco Miguel , Ferasso Marcos , Bares Lydia
Published: March 2021

The Renewable Energy Plan for the period 2011–2020 established as a general goal to ensure that renewable sources represent at least 20% of final energy consumption in 2020, together with a minimum contribution of 10% from renewable energy sources in transportation for that year. Then, the goal of this research is to evaluate the effects of the regional production of clean energy, identifying the employment generated in the renewable sector. The adopted methodology was the shift-share analysis, frequently used by researchers to analyze territorial differences. Main results showed important differences, at regional level, in the production of this type of energy. Likewise, we used constant shift and constant share methodology to make a forecast on the evolution of the sector from the data of last published years. Pending the approval of the new Renewable Energy Plan for the period 2021–2030, the results obtained in this research allow the identification of the regions that showed a favorable evolution to the energy change and identifies the projects that generate employment and production in the sector.

Published: March 2021

The main purpose of this paper is to show and introduce some new interpretative aspects of the concept of “emergent space” as geometric/topological approach in the cosmological field. We will present some possible applications of this theory, among which the possibility of considering a non-orientable wormhole, but mainly we provide a topological interpretation, using this new approach, to M-Theory and String Theory in 10 dimensions. Further, we present some conclusions which this new interpretation suggests, and also some remarks considering a unifying approach between strings and dark matter. The approach shown in the paper considers that reality, as it appears to us, can be the “emerging” part of a more complex hidden structure.

Compared to free antigens, antigens immobilized on scaffolds, such as nanoparticles, generally show improved immunogenicity. Conventionally, antigens are conjugated to scaffolds through genetic fusion or chemical conjugation, which may result in impaired assembly or heterogeneous binding and orientation of the antigens. By combining two emerging technologies—i.e., self-assembling multimeric protein scaffold particles (MPSPs) and bacterial superglue—these shortcomings can be overcome and antigens can be bound on particles in their native conformation. In the present work, we assessed whether this technology could improve the immunogenicity of a candidate subunit vaccine against the zoonotic Rift Valley fever virus (RVFV). For this, the head domain of glycoprotein Gn, a known target of neutralizing antibodies, was coupled on various MPSPs to further assess immunogenicity and efficacy in vivo. The results showed that the Gn head domain, when bound to the lumazine synthase-based MPSP, reduced mortality in a lethal mouse model and protected lambs, the most susceptible RVFV target animals, from viremia and clinical signs after immunization. Furthermore, the same subunit coupled to two other MPSPs (Geobacillus stearothermophilus E2 or a modified KDPG Aldolase) provided full protection in lambs as well.

Increasing the production of milk and dairy products to provide the population of country with complete-fl edged food is an important task, which requires not only increasing the productivity of animals, but also using energy- and resource-saving technologies in their production to increase the eff ectiveness and profi tability of the industry. New solutions for the development of agricultural enterprises should take into account the requirements of time not only to increase production, but also to reduce prime-costs for it. In a market economy in the fi eld of agriculture in particular in dairy farming in the chain from the supplier of raw materials to the sale of the fi nal product, the least profi table is the production of raw materials. Therefore, the use of mini dairy shops for processing milk directly in the conditions of an agricultural enterprise should increase the eff ectiveness of dairy cattle breeding. The issues of effi ciency of milk processing under the conditions of an agricultural enterprise using a modular dairy shop for the production of fi nished dairy products have been considered in the paper. In the considered modular dairy shops traditional technological processes for the production of pasteurized milk and sour cream are used. Modular dairy shop KOLAKS-5001 only processing pasteurized milk with fat content of 3,71 %, packaged in plastic bags and modular dairy shop KOLAKS-5002 processing pasteurized milk 2,5 % fat, packaged in plastic bags and sour cream 20 % fat, packaged in plastic cups. As a result of the evaluation of the effi ciency of using a modular dairy shop, it was found that it will increase the eff ectiveness of milk production and pay back for equipment costs within 1,5 months.

Published: March 2021

Scientific and production experiment has been carried out in the period 2007–2017 at pig complexes JSC “Smolmyaso” in the Smolensk region and LLC “Myasokombinat Stupinsky”, LLC APC “Mashkino” in the Moscow region to determine the meat productivity and quality of pork of domestic, Canadian and French breeding of different breeds. Young pigs have been reared to a live weight of 95–105 kg. The conditions for housing and feeding of young animals of all the experimental groups have been identical. The purpose of the researches was to study the chemical composition and technological properties of pig meat of domestic, Canadian and French breeding. It has been found as a result of studies to determine the chemical composition that a higher content of protein and fat in meat of carcasses was in subgroup 2,3 of Canadian breeding (Large White × Landrace × Duroc) – 21,9 and 5,8 %, respectively, which has exceeded the best performance in domestic groups (subgroup 1,3–19,3 % protein and 11,8 % fat) and French breeding (subgroup 3,3–21,8 % of the protein and subgroup 3,2–7,8 % of fat). When determining the technological properties of pork, it has been found that the best moisture–binding capacity was characterized by the meat of pigs of domestic selection of all breed combinations – 62–64 %. During storage, it was the pigs of domestic selection that had the lowest losses of raw material weight – 1,4–1,7 %, while in the group of pigs of Canadian breeding; these losses were about 2 %, and in the group of French breeding – 2,5–2,8 %. According to its chemical composition the meat of pigs of Canadian selection exceeded the indicators of young pigs of domestic and French breeding, but it was not inferior in its technological properties to the meat of pigs of domestic selection. Consequently, in the technology of obtaining meat products to use crossbred pigs of Canadian breeding will be more rational.

Authors: Bibikov S. O. , Shapovalov S. O.
Published: March 2021

The results of applying microscopic methods of analysis of pig feces to assess the digestibility of feed and diagnose various diseases of the gastrointestinal tract have been presented in the article. The microscopic method allows you to identify detritus, undigested fi ber, raw fat, fragments of animal feed ingredients, starch in the feces, gives an idea of the presence of foreign impurities (due to perverted appetite, contamination of feed), helminths, their eggs and other intestinal parasites. A number of preparations have been prepared to identify feed nutrients and feed components of the diet, and a number of coloring reagents were also used: Lugol’s solution for recognizing starch and its cleavage products (amylodextrin and erythrodextrin), Saathof’s reagent for detecting fat, and Hecht’s reagent for diff erentiating fat elements. The researches have been carried out under various magnifi cations of the microscope. Diff erent levels of detritus and undigested elements of feed in animals under the same conditions of rearing and feeding can identify individual features of digestion. The microscopic method of analysis does not require expensive equipment, reagents, and allows you to get the results of assessing the digestibility much faster than the methods of classical “wet” chemistry. This research method can be used by nutritionists to correct diets when using exogenous feed enzymes: phytase, xylanase, gluconase, amylase, mannanase, lipase, protease, etc., and provide results for discussion about the presence or absence of matrix eff ects from their use. The results of feces microscopy can give then idea of the quality of feed ingredients used: the content of non-starchy polysaccharides and the level of grain viscosity, the quality of animal ingredients (meat-bone, feather, fi sh meal), the level of indigestible fi ber in sunfl ower and soybean meals.

Introducción: el objetivo del presente manuscrito fue describir las principales características epidemiológicas de la denominada primera curva epidémica causada por la enfermedad Covid-19 en Costa Rica entre 06 de marzo y hasta el 24 de abril del 2020.  Metodología: se realizó un estudio observacional descriptivo de los casos de pacientes con enfermedad por la COVID-19 en Costa Rica durante las semanas epidemiológicas 10 a la 17.  Los datos que se utilizan en este trabajo fueron tomados y resumidos de los reportes, informes diarios y actualizaciones que se publican en los sitios de dominio público de la Caja Costarricense del Seguro Social (CCSS) y el Ministerio de Salud de Costa Rica (MINSA), instituciones que tienen el mandato constitucional y legal de la atención y la vigilancia de la salud, respectivamente, en todo el territorio nacional. Estos datos se consolidaron y procesaron en una hoja de cálculo de Excel ®.  Resultados: al final de esos 50 días de la primera curva, hubo un total de 687 pacientes confirmados, entre los 1 y 87 años, 52% masculinos (n= 359), afectando al 0,013 % de los habitantes censados del país (n: 5 111 238) con una letalidad del 0,87 %. El promedio de casos nuevos diarios fue de 13,8, la mediana de 16 y la moda 19.  90% de los casos fueron nacionales (n= 620) y el 10% (n= 67) eran extranjeros, incluyendo residentes formales. La distribución según edad fue de un 91% de pacientes adultos (n= 618), un 5,1% de adultos mayores (n= 35) y un 4,9% de menores de edad (n= 34). Durante la primera curva epidémica, se logró realizar el seguimiento de los casos y establecer los conglomerados, lo cual facilitó las labores de atención por parte del personal de salud.  Conclusión: a diferencia de otros países, la primera curva epidémica en Costa Rica representó un periodo particular de bajo estrés (pocos casos y baja letalidad de estos) para el sistema nacional de salud, que pudo ser aprovechado para fortalecer las intervenciones en comunidades de riesgo potencial, tales como asentamientos humanos ubicados en plantaciones fronterizas, tugurios y cuarterías, y también para reforzar la educación para la salud en la población, así como dotar al sistema de salud de mayores recursos para atender la segunda ola epidémica.

Mapping Crop Phenology in Near Real-Time Using Satellite Remote Sensing: Challenges and Opportunities
Authors: Gao Feng , Zhang Xiaoyang
Published: March 2021

Crop phenology is critical for agricultural management, crop yield estimation, and agroecosystem assessment. Traditionally, crop growth stages are observed from the ground, which is time-consuming and lacks spatial variability. Remote sensing Vegetation Index (VI) time series has been used to map land surface phenology (LSP) and relate to crop growth stages mostly after the growing season. In recent years, high temporal and spatial resolution remote sensing data have allowed near-real-time mapping of crop phenology within the growing season. This paper summarizes two classes of near-real-time mapping methods, i.e., curve-based and trend-based approaches. The curve-based approaches combine the time series VIs and crop growth stages from historical years with the current observations to estimate crop growth stages. The curve-based approaches are capable of a short-term prediction. The trend-based approaches detect upward or downward trends from time series and confirm the trends using the increasing or decreasing momentum and VI thresholds. The trend-based approaches only use current observations. Both curve-based and trend-based approaches are promising in mapping crop growth stages timely. Nevertheless, mapping crop phenology near real-time is challenging since remote sensing observations are not always sensitive to crop growth stages. The accuracy of crop phenology detection depends on the frequency and availability of cloud-free observations within the growing season. Recent satellite datasets such as the harmonized Landsat and Sentinel-2 (HLS) are promising for mapping crop phenology within the season over large areas. Operational applications in the near future are feasible.

Do pandemics lead to rebellion? Policy responses to COVID-19, inequality, and protests in the USA
Authors: Iacoella Francesco , Justino Patricia , Martorano Bruno
Published: March 2021

This paper analyses how inequality across counties in the United States of America has shaped the impact of the COVID-19 pandemic on the incidence of protests. The empirical analysis combines weekly data between January and December 2020 on levels of COVID-19-related policy stringency and protest incidence at the county level with measures of county-level inequality at the start of the pandemic. The results show that more stringent measures to contain the pandemic were instrumental in driving the incidence of protests, but only in counties with high levels of inequality before the start of the pandemic, where grievances may have been initially stronger. Further analysis suggests that the impact of government responses to the COVID-19 pandemic is largely explained by changes in economic conditions (rise in unemployment and changes in economic activities and spending) in counties with the highest levels of inequality. Unequal counties with lower trust in political institutions but higher levels of social trust and civic engagement at the start of the pandemic are also more likely to experience more protests as a response to more stringent policies.
Influence of Preheating on the Mechanical Properties of High Strength Concrete with Micro Silica Filler
Authors: ALAMERİ Ibrahim , OLTULU Meral , ARDAHANLI Metehan
Published: March 2021

The early-age temperature of concrete containing silica fume is very important due to the tendency of the silica-fume surface to react quickly and increase strength. The curing method directly affects the permeability, strength, and durability of concrete. In this study, the effects of preheating on the compressive, splitting tensile and flexural tensile strengths of concrete with different ratios of silica fume were investigated. Three different mold type samples were used: 15 × 15 × 15 cm cube samples for the compression test, 10 × 20 cm cylinder samples for the tensile test, and 7 × 7 × 28 cm beam samples for the bending tensile strength test. As a mineral additive, silica fume was replaced by 8%, 10%, and 12% by weight of cement. Two groups were prepared for the test, group A was left in water for 4 weeks, group B was preheated for 1 day at 75°C, and then left in water for 4 weeks. The results showed that the best addition of silica fume was 10%, which increased workability and reduced the effect of early-age temperature.

Se documentaron experiencias profesionales de publicidad social para ONG, desde perspectivas sistémicas de la escritura y la comunicación profesional. Estudios sobre la escritura profesional han documentado la importancia de incluir perspectivas sistémicas que visibilicen cómo viajan las producciones escritas y entre quiénes. Los enfoques sistémicos exploran el comportamiento humano colectivo en el marco de interacciones cooperativas y competitivas, en las que hay una división social del trabajo, así como acceso jerárquico a recursos, derechos y deberes. Con dicho enfoque, se desarrolló un estudio basado en entrevistas estructuradas a ocho profesionales de la comunicación y la publicidad. El protocolo de entrevista constó de 21 preguntas sobre: 1) información de la organización, 2) perfil y trayectoria profesional, 3) descripción de un proyecto profesional desafiante, y 4) descripción de la ruta de procedimientos para producir un entregable desafiante. Los análisis confirman que la escritura y la comunicación profesional en publicidad social tienen interacciones con la educación; es decir, el uso de la comunicación como medio para promover el cambio. También, se observa que llevar a cabo proyectos profesionales en ONG tiene lugar en una ecología de entregables, vistos como productos intermedios (bocetos, prototipos o borradores) y finales (manuales de campaña, sitios web, murales). Los resultados pueden usarse para diseñar experiencias de aprendizaje con casos profesionales de simulación, como los reportados en este estudio.
