Photochemical synthesis of ammonia and amino acids from nitrous oxide
Authors: Zang Xiaofeng , Ueno Yuichiro , Kitadai Norio
Published: May 2021

Abiotic synthesis of ammonia and amino acids are important for origin of life and early evolution. Ammonia (NH3) and organic nitrogen species may be possibly produced from nitrous oxide (N2O), which is a second abundant nitrogen species in the atmosphere. Here, we report a new photochemical experiment and evaluate whether N2O can be used as a nitrogen source for prebiotic synthesis in the atmosphere. We conducted a series of experiments using a gas mixture of N2O+CO, N2O+CO2 or N2O+H2 with the presence of liquid water. The results demonstrated that NH3, methyl amine (CH3NH2) and some amino acids such as glycine, alanine and serine can be synthesized through photochemistry from N2O even without metal catalysts. NH3 can be produced not only from CO+N2O, but also from H2+N2O. Glycine can be synthesized from CH3NH2 and CO2, which can be produced from N2O and CO under UV irradiation. Our work demonstrated for the first time that N2O could be an important nitrogen source and provide a new process for synthesizing ammonia and organic nitrogen species that was not considered previously. Contribution of organic synthesis from N2O should therefore be considered when discussing the prebiotic chemistry on primitive Earth.
The Wisdom of Model Crowds
Authors: He Lisheng , Analytis Pantelis P. , Bhatia Sudeep
Published: May 2021

A wide body of empirical research has revealed the descriptive shortcomings of expected value and expected utility models of risky decision making. In response, numerous models have been advanced to predict and explain people’s choices between gambles. Although some of these models have had a great impact in the behavioral, social and management sciences, there is little consensus about which model offers the best account of choice behavior. In this paper, we conduct a large-scale comparison of 58 prominent models of risky choice, using 19 existing behavioral datasets involving more than 800 participants. This allows us to comprehensively evaluate models in terms of individual-level predictive performance across a range of different choice settings. We also identify the psychological mechanisms that lead to superior predictive performance and the properties of choice stimuli that favor certain types of models over others. Second, drawing on research on the wisdom of crowds, we argue that each of the existing models can be seen as an expert that provides unique forecasts in choice predictions. Consistent with this claim, we find that crowds of risky choice models perform better than individual models and thus provide a performance bound for assessing the historical accumulation of knowledge in our field. Our results suggest that each model captures unique aspects of the decision process, and that existing risky choice models offer complementary rather than competing accounts of behavior. We discuss the implications of our results on theories of risky decision making and the quantitative modeling of choice behavior.
Temporal Transitions of Demographic Dot Maps
Authors: Allen Jeff
Published: May 2021

Dot maps are often used to display the distributions of populations over space. This paper details a method for extending dot maps in order to visualize changes in spatial patterns over time. Specifically, we outline a selective linear interpolation procedure to encode the time range in which dots are visible on a map, which then allows for temporal queries and animation. This methodology is exemplified first by animating population growth across the United States, and second, through an interactive application showing changing poverty distributions in Toronto, Canada.

Published: May 2021

The purpose of the article is to reveal the essence and main directions of state regulation of the development of entrepreneurship in the agricultural sector in modern conditions. Research methods. The methodological basis of the study was a set of methods of scientific knowledge of the system and mechanism of state regulation of the development of entrepreneurship in the agricultural sector. The achievement of the goal was facilitated by general scientific methods: methods of empirical research (measurement, comparison, observation); methods of theoretical research (analysis and synthesis); as well as local (specific) methods: methods of situation analysis (computational-constructive method). Research results. It has been established that state regulation of the development of entrepreneurship in the agricultural sector is the integrity of the implemented protectionist measures that guarantee the financial, budgetary, legal, economic, investment security of the competitive functioning of business entities in a market environment in order to optimize the conditions and consequences of entrepreneurial activity, the formation of a decent level of food security of the state, adaptation of producers to modern conditions of instability and coronacrisis. It is substantiated that the financial costs for state support of agricultural producers should be at least 1% of the volume of agricultural production, but in reality they amount to 0.4%. It was revealed that agricultural producers do not have real tax support. It has been established that the implementation of the priority of state regulation of small business entities, individual entrepreneurs and households will only contribute to an increase in the integral efficiency of the use of budgetary funds. Scientific novelty. The essence and main directions of state regulation of the development of entrepreneurship in the agricultural sector in modern conditions are disclosed and a methodological approach to substantiating the main directions of modification of state regulation that contributes to solving the problems of the functioning of entrepreneurship in the agricultural sector of the economy is proposed.

To ensure required complex of steel strength properties, pipes heat treatment is widely used as a quenching for martensite followed by tempering. It is accepted, that metal microstructure formed at that, has a little effect on a steel corrosion resistance in carbon dioxide mediums. Studies were accomplished of steel microstructure effect of the carbon dioxide corrosion speed. In particular, a low-alloyed structural steel, used for production of oil field pipes was selected. As the object of the study, seamless pumpcompressor pipes (PCP), made of medium-carbon steels of several grades with chrome content about 1% (mass.), subjected to two methods of heat treatment: quenching with tempering or normalization with tempering. Corrosion resistance of the steels were accomplished  under  laboratory  conditions of  JSC  “RusNITI”  by  application  of  autoclave  facility  imitating  operation  conditions  parameters of a working medium at oil extraction. The speed of general metal corrosion was measured as samples mass loss during tests (from 360 to 70 hours) by gravimetric method. By the results of laboratory tests the steel 35ХГФА was recommended to the industrial production of PCP of K72 and N80 strength groups due to GOST 31446 with normalization and tempering. It was established that pipes of steel 35ХГФА with ferrite-pearlite microstructure have higher corrosion resistance in mineralized water mediums at  carbon  dioxide  partial  pressure  up  to  0.20  atm,  comparing  with  regular  pipes,  manufactured  with  quenching  and  tempering.  A complex of field tests of PCP was carried out, the pipes made of experimental steel 35ХГФА at an oil deposit. The result of operation of CPC of 88.9×6.45 mm made of steel 35ХГФА having K72 group of strength (after normalization with tempering) during 550 days under conditions of high-mineralized water phase at СО2 partial pressure up to 0.27 atm was found positive. After an intermediate inspection (550 days) the column of PCP was assembled and is in operation at present, the current running time exceeding 1000 days. Based on the results of the complex comparative tests carried out in the corrosion laboratory and under field oil extraction conditions it was established that usage of experimental steel 35ХГФА containing 1% of Cr, after application of normalization technology with tempering resulted in increasing of operating reliability of CPC.

Remittances from Mexican migrants in the United States during the time of COVID-19
Authors: Zamora Rodolfo Garcia , Gaspar Olvera Selene
Published: May 2021

Following the Great Recession of 2007-2009 in the United States, Mexican migrants’ remittances began to grow steadily in 2014 until they reached a historical level of US$36 billion in 2019. This figure was at US$4 billion in March 2020 when Mexico had been suffering the effects of COVID-19 for one month. In April, remittances from Mexican migrants in the United States dropped 28%, as their unemployment rate reached 17%. Recuperating remittance levels will depend on economic recovery policies in the United States, and on reducing unemployment for Mexican migrants in the sectors where they have the biggest presence.

Published: May 2021

Introducción: En las mujeres virgenes, que no han tenido ninguna copula carnal, existe en la linea de union vulvovaginal una especie de membrana incompleta que se extiende hacia el centro del orificio estrechando su luz, se conoce con el nombre de himen y estos pueden ser típicos o atípicos. Metodologia: Se realizó una revisión y anàlisis de la bibliografia, sobre los distintos tipos de hímenes, lo que permitió identificar un himen atípico no frecuente y tenerlo como punto de referencia en casos semejantes que se pudieran  presentar en el futuro. Conclusiones: El himen con doble atipicidad, septado, con un orificio dilatado, es poco descrito en la bibliografía consultada. Durante el reconocimiento por delito sexual los peritos médicos legistas actuantes, deben tener presente la existencia de hímenes como este. En estos casos de delitos sexuales en los que la víctima tenga un himen con estas características, la tipificación del delito dependerá de la investigación policiológica.
