Financiarización subordinada en América Latina: dolarización, endeudamiento externo e internacionalización de la riqueza
Authors: Malic Estanislao , Santarcángelo Juan
Published: October 2022

La financiarización remite al proceso mediante el cual mercados, actores, instrumentos e instituciones financieras ganan importancia en el funcionamiento de las economías y donde el excedente generado se destina hacia la acumulación financiera, que desplaza la acumulación productiva (Epstein, 2005). Sin embargo, este proceso es heterogéneo entre regiones y países, y se presenta en la periferia en la forma de “financiarización subordinada”, ya que las dinámicas de acumulación global condicionan su inserción asimétrica y dependiente. El presente trabajo pretende examinar un conjunto de aspectos centrales del proceso de financiarización subordinada de los países de América Latina, el cual se manifiesta en la pérdida de espacios monetarios soberanos que se vinculan con el proceso de dolarización de los sistemas bancarios, el grado de endeudamiento y la internacionalización de la riqueza.
Política industrial, antes y ahora
Authors: Chick Victoria
Published: October 2022

Después de 40 años de neoliberalismo, hasta los gobiernos creen que son ineficientes cuando se comparan con el sector privado. La teoría económica, con su giro a la derecha, refuerza esta idea. La filosofía detrás del gasto público con objetivos sociales, así como los criterios con los que se juzgan esos proyectos no han sido objeto de debate público sino hasta muy recientemente. La política industrial era muy simple: dejar al sector privado la distribución de los recursos, de acuerdo con lo que decidiera el mercado. En tiempos de Keynes así no eran las cosas. El presente artículo reflexiona sobre algunos de los problemas de la política industrial que surgieron durante el periodo de entreguerras. Se necesita revivir el debate, revisarlo y, donde sea necesario, actualizarlo, con el fin de hacerlo corresponder con el presente; por ello, mucho puede aprenderse de los principios básicos discutidos entre una guerra y otra. El contraste entre el reciente Libro Blanco sobre estrategia industrial (2018) del gobierno de Reino Unido y la Consulta Industrial Liberal El futuro industrial británico (1928) es muy aleccionador.

Fungi are now gaining attention as a tool for water quality due to their implication in waterborne infections. The effect of human activities on the population, distribution and diversity of fungi in Lobia Creek was investigated. Water samples were collected from five designated stations along Lobia creek into separate sterile bottles. Samples were transported in ice packed coolers to the laboratory for analysis using standard mycological techniques. A total of 60 water samples were analyzed during the six months sampling period (August 2020 to January 2021). Results of fungal count for toilet, jetty, abattoir, drinking and control were 2.1±0.42×104cfu/ml, 1.1±0.14×104cfu/ml, 1.9±0.14×104cfu/ml, 7.0±0.04×102cfu/ml, and 7.0±0.01×102cfu/ml, respectively. The decreasing order of fungal population in the stations was; Toilet ˃ Abattoir ˃ Jetty ˃ Drinking water ˃ Control. Statistical analysis showed that, there was significant difference (p<0.05) across the sampled stations. Results also showed that the fungal counts recorded in the toilet station was not significantly different (P>0.05) from the counts recorded for the jetty and abattoir station despite being slightly higher but was significantly higher (P<0.05) than the counts recorded for drinking and control samples. Percentage occurrences for fungal isolates were: Rhizopus sp (2.3%), Penicillium sp (27.3%), Mucor sp (15.9%), Candida krusei (9.1%), A. niger (11.4%), Saccharomyces sp (4.5%), Fusarium sp (10.2%), Aspergillus sp (11.4%) and Candida sp (8.0%). The decreasing order of the types of fungi in the locations was; Toilet ˃ Abattoir ˃ Jetty ˃ Control ˃ Drinking water. The high fungal load and uneven distribution of fungal types in all stations is attributed to the type of human activity in respective station. The fungi reported are known potential pathogens that can cause respiratory, skin and soft tissue infections and poses health risk to the public.

An experiment was conducted during rabi season of 2016-2017 at Agricultural College and Research Institute, Killikulam to study nutrient removal pattern of weeds due to integrated weed management practices in hybrid maize. Weeds compete with crops for nutrients and nutrient removal by weeds is a serious problem in a widely spaced crop like maize. Adoption of various weed control treatments exhibited significant influence on N removal by weeds on 20 DAS. Application alachlor @ 1.5 kg a.i ha-1 as pre- emergence with one hand weeding on 30 DAS (T2) registered significant lowest N removal of 5.8 kg ha-1 by weeds. The next best treatment was mechanical weeding with power weeder twice on 15 and 30 DAS (T11) which recorded a removal of 6.9 kg ha-1 N by weeds. Unweeded control (T12) recorded highest N removal by weeds (13.2 kg ha-1) which was statistically on par with the treatments T3 and T1. Pre-emergence application of alachlor @ 1.5 kg a.i ha-1 with one hand weeding on 30 DAS (T2) reduced the weed population, weed dry matter production and nutrient removal (N, P and K) by weeds.

Published: October 2022

The perinatal period is a most crucial time in the development of a young chick as this is a transitional period in which the chicks undergo metabolic and physiological shifts from the utilization of egg nutrients to exogenous feed. The in ovo feeding allows the delivery of various supplements directly to chicken embryos which enhances digestive capacity, growth rate, muscle development, feed conversion efficiency and immunity. Hence, the present study was aimed to examine the effect of in ovo injection of nano forms of zinc, copper and chromium on morphometry of digestive organs and immune response in broiler chicken. In this study, four hundred fertile broiler eggs from Cobb 430 flock were randomly divided into five treatment (80 eggs each) groups. First treatment was without injection (control), second was injectedwith0.5ml normal saline, third, fourth and fifth treatment eggs were injected with 40, 12 and 0.5 µg/egg of nano zinc, nano copper and nano chromium, respectively. After hatching, 240 day old straight run broiler chicks were allocated into five treatment groups each consisting of four replicates with twelve chicks and all birds were fed with broiler starter diet (1-21 days) and finisher diet (22-42 days) as per NRC (1994). In ovo feeding of nano forms of zinc, copper and chromium at18th day of incubation through amniotic route did not influence the growth performance of broiler chicken. However, better serum glucose, total protein and globulin levels were observed in nano trace mineral supplemented groups.

Published: October 2022

Previously, using the conjugate frame-based reconciliation approach, we defined a method to correct errors produced in pairs of non-orthogonal quantum states that are transmitted through a quantum key distribution (QKD) link. The security of the frame-based reconciliation was discussed in order to deal with Photon Number Division (PNS) attack and Intercept and Forward (IR) attack, among others.
However, until the time of publication we did not have the distillation software to test our method. In this article, following the conjugate frame distillation method, we present the implementation of the post-processing system that demonstrates that it is capable of correcting errors in the presence of error rates close to unity. The system shows that when the number of double-sensing events at Bob's station is as low as 100, the number of secret bits stays above 4500 bits in about 12 seconds, giving a secret rate of 375 bits per second while that the channel error rate reaches 90\%.

Published: October 2022

Carrot juice and its associated beverage products are well-known healthy drinks all over the world. However, what effect carrot juice has on the human gut microbiota and how it is fermented by the intestinal microbes have not been studied. Here, using an in vitro model of anaerobic fermentation, we demonstrated that carrot juice could be fermented into lactate and acetate by the human gut microbiota. 16S high-throughput sequencing and bioinformatic analyses indicated that fermentation of carrot juice could significantly change the composition of the human gut microbiome. Interestingly, carrot juice remarkably increased the abundances of beneficial bacteria, including Lactobacillus fermentum, Lactobacillus salivarius, Lactobacillus mucosae and Bacteroides uniformis and decreased the population of opportunistic pathogenic bacteria, such as Enterococcus faecium in the gut. Collectively, our study illustrates a favorable effect of carrot juice on the human gut microbiota and lays a foundation for the development of carrot juice as a novel prebiotic agent.

Published: October 2022

While shoulder injuries represent the musculoskeletal disorders (MSDs) most encountered in physical therapy, there is no consensus on their management. As attempts to provide standardized and personalized treatment, a robot-ic-assisted device combined with EMG biofeedback specifically dedicated to shoulder MSDs has been developed. The aim of this study was to determine the efficacy of an 8-week rehabilitation program (≈3 sessions a week) using a ro-botic-assisted device combined with EMG biofeedback (RA-EMG group) in comparison with a conventional program (CONV group) in patients presenting with shoulder MSDs. This study is a retrospective cohort study including data from 2010 to 2013 on patients initially involved in a physical rehabilitation program in a private clinic of Chicoutimi (Canada) for shoulder MSDs. Shoul-der flexion strength and range of motion were collected before and after the rehabilitation program. Forty-four patients participated in a conventional pro-gram using dumbbell (CONV group) while 72 of them completed a program on robot-assisted device with EMG and visual biofeedback (RA-EMG group), whereby both programs consisted in 2 sets of 20 repetitions at 60% of maximal capacity. Results showed that the RA-EMG had significantly greater benefits than the Conv group for shoulder flexion strength (+103.1% vs 67%, p = 0.016) and range of motion (+14.4% vs 6.1%, p = 0.046). The current retrospective co-hort study showed that a specific and tailored rehabilitation program with constant effort by automatic adjustment of the level of resistance was able to potentiate strength and range of motion shoulder flexion after an 8-week reha-bilitation period in comparison with a conventional approach in patients with shoulder MSDs. This study provides new insight on shoulder MSD rehabilita-tion and future research should be pursued to determine the added potential of this approach for abduction and external rotation with a randomized controlled design.

Методами математического моделирования получены характеристики неравновесного теплообмена меди, такие как теплопроводность и теплоемкость в широком
температурном диапазоне ($300 \leqslant T \leqslant 5700$ K), включающем область фазовых трансформаций плавление-кристаллизация. Как известно, в твердом теле существуют
два механизма переноса тепла: упругими колебаниями решетки и свободными
электронами. При определении этих характеристик теплообмена меди учитывались
решеточные и электронные составляющие. Моделирование характеристик теплообмена электронной подсистемы меди в данной работе основано на использовании
квантовой статистики электронного газа с использованием интегралов Ферми-Дирака. Свойства фононной подсистемы определялись в рамках атомистического подхода. Для моделирования использовался потенциал взаимодействия частиц семейства “погруженного атома” EAM. Результаты моделирования сравнивались с результатами альтернативных вычислений. Полные теплоемкость и теплопроводность меди, полученные суммированием электронной и фононной составляющих,
сравниваются с данными эксперимента.

The issues of efficiency improvement in hydrodynamic (liquid) or limit (semi-liquid) modes of friction of gears with an asymmetric profile and the effect of the liquid on tooth damage, power loss and temperature in contact, as well as the role of an elastic medium that dampens shocks and changes contact lines, are considered. In many gears, the tooth load per tooth is much higher and applied for longer periods of time. The asymmetrical shape of the tooth reflects this functional difference. In the case of asymmetric gears, the standard symmetrical toothed tool rail is modified by changing the pressure angle of one of the side surfaces. However, this simplistic approach to the design of an asymmetric transmission significantly limits the ability to maximize the performance of a wide range of possible applications of these transmissions. As the frequency of impact interactions increases, the lubricating layer of high-speed gears with an asymmetric profile ceases to respond to pressure changes, and the load value, which determines the smallest layer thickness over time, approaches the minimum stationary component of the spectrum of dynamic loads. At the same time, noise and vibration levels are slightly reduced. Therefore, in the calculations of the strength, contact endurance and seizure of high-speed gears with an asymmetric profile, the complex influence of the criterion parameters of the lubricant must be taken into account not only when determining the allowable stresses, but also when determining the amount of dynamic load amplification due to the impact interaction of the teeth.

Published: October 2022

An updated mathematical model for determining the elastic displacements that occur in the technological system during machining, which summarizes the analytical description of the elastic displacement during grinding and blade machining. This allowed us to establish that the smallest elastic displacements can be ensured during grinding by significantly exceeding the speed of the cutting speed during blade machining. However, the energy consumption of processing is much higher (up to 10 times) than with blade processing, which limits the technological capabilities of grinding. Therefore, in finishing operations to effectively use the technology of blade processing. This is especially true of high-speed cutting technologies, which from a kinematic point of view are not inferior to grinding and provide a reduction in elastic displacements, energy consumption and increase the accuracy and productivity of processing. It is established that processing of openings in several passes is expedient to carry out drills with various diameters, increasing diameter on passes. It is shown that it is easier to ensure the required accuracy when boring than when machining with axial tools. By milling holes, an even greater increase in machining accuracy and productivity can be achieved.

DEVELOPMENT OF THEORETICAL APPROACH TO DETERMINATION OF CUTTING TEMPERATURE DURING GRINDING AND CONDITIONS OF ITS REDUCTION
Authors: Nоvikоv Fеdir , Polyansky Vladimir
Published: October 2022

The paper develops a theoretical approach to determining the cutting temperature during grinding and the conditions for its decrease, taking into account the balance of heat leaving the chips and the workpiece. It has been established that with an increase in the contact time of the wheel with the material being processed, the cutting temperature continuously increases, asymptotically approaching the maximum cutting temperature, which is determined by the ratio of the conditional cutting stress to the specific heat capacity and density of the material being processed. Based on this, it is proposed to consider the maximum cutting temperature as a new universal technological processing parameter that determines its potential and allows comparing various machining methods according to the temperature criterion and choosing the most effective of them. On this basis, the main direction of reducing the cutting temperature and improving the quality and productivity of processing is substantiated, which consists in reducing the maximum cutting temperature to the level and below the melting temperature of the material being processed. This makes it possible to carry out grinding with a significant machining capacity with virtually no increase in cutting temperature. It is shown that the main condition for reducing the maximum cutting temperature is to reduce the conditional cutting stress.

It is revealed that the structural changes that occur in the surface microlayer of conjugate materials, the formation and destruction of secondary structures are responsible for the nature of the friction node. The authors propose to create on the friction surface such protective coatings that have properties and mechanism of action corresponding to secondary structures in order to be able to control the phenomena of antifriction and fractionality in the friction zone of conjugate parts. The aim of the study is achieved by processing iron-carbon alloys in the environment of superheated steam of aqueous solutions of salts. The optimal parameters of the technological process of forming coatings during vapor oxidation are selected. Laboratory tests of different chemical composition of the formed coating on the tribotechnical properties of friction steam were carried out. During the study, the authors concluded that by establishing a qualitative and quantitative relationship between the composition of oxide coatings and their tribotechnical properties, it is possible to change the conditions of the friction unit from antifriction to friction, using the same structural materials - ferrocarbon alloys. Thus, complex oxides, which differ in chemical composition and structure, which are coatings on ferrocarbon alloys, can significantly affect the thermomechanophysical processes that occur during operation and allow their renovation in the presence of lubricant and without it. Coatings formed on the surface of ferrocarbon alloys in accordance with the operating conditions can have both friction and antifriction properties.

The purpose of the article is to describe the practical aspects of identifying gel drinks based on collagen to identify signs of their possible falsification. The article analyzes technological aspects and influencing factors on the formation of quality indicators and consumer properties of collagen-based gel drinks. The main organoleptic characteristics of the quality and attractiveness of new types of health drinks based on collagen are also considered. Attention is focused on methods of checking and achieving a high quality level of input raw materials and additional components. The production technology in industrial conditions is presented by analyzing the stages and technological process and the stages of preparation of recipe components for their participation in the technological process. Also considered are practical recommendations for the qualitative identification of gel drinks in order to detect adulterated products containing gelling agents of a non-protein nature. In Ukraine, gel drinks are only gaining popularity, but collagen-based drinks in the form of shots are a novelty for the domestic beverage market, as they mostly belong to the "beauty" industry and sports and fitness nutrition. Today, collagen drinks are presented either in the form of dry drinks (fast-dissolving form) or foreign production. In connection with the reduced solvency of ordinary Ukrainian citizens and the course of the Ukrainian government on import substitution, the presented development is predicted not only to gain popularity among supporters of a healthy lifestyle, but also to take a leading position in the near future among those who seek to postpone the signs of aging or prevent premature aging. The contingent of such consumers will grow every year, because the issue of prolonging youth is no longer a matter of time, but of modernity, since the increase in the retirement age requires the working population to be active and energetic, smooth and speed of movements, intensity of brain activity and long-term concentration of attention for at least 15-20 years more than was necessary even 5 years ago. Therefore, it is extremely important to prevent the actions of unscrupulous manufacturers who will look for ways to reduce the cost of gel drinks based on collagen, replacing the main component with polysaccharide gelling agents, which provide a similar consistency with a small content, but at the same time do not have the healing effect that collagen has for the human body . The article outlines aspects of the identification of collagen-based gel drinks; the need for their identification to identify possible signs of falsification is substantiated, methods for performing such studies are given.

To preserve and strengthen the health of young people, one of the tasks of the state in the field of healthy nutrition is the development of the production of functional food products enriched with the necessary macro- and microelements; development of supplements of biologically active substances and orientation of higher education to increase the level of valeology students, and introduction of relevant topics and subjects into the educational process of higher educational institutions. The article is devoted to the problem of monitoring chemicals in the nutrition of student youth in modern conditions. With the help of a questionnaire and the method of determining the content of micro- and macroelements in the daily diet, non-compliance with the principles of rational nutrition by full-time students was revealed, which negatively affects their health. For all full-time students, there is a deficit of iodine consumption, a deficit of 50.2% of phosphorus, 64.7% of zinc, and 56.2% of chromium. The average content of calcium in daily rations was less than recommended by approximately 1.7 times for girls and 1 .95 times for young men, and calcium deficiency was found in 97.9% of students, and magnesium deficiency in 82.4%. The intake of Ferrum, Manganese, Selenium and Copper with food rations exceeds the recommended values. The study of the quality of the diets of junior year students showed that the majority of students have a polydeficient, unbalanced diet in terms of micro- and macroelements, as well as a lack of a conscious attitude to nutrition. A low level of students' abilities and skills in organizing their own food was revealed. An insufficient level of knowledge about proper nutrition is a potential factor in the deterioration of health, the occurrence of primary and secondary alimentary diseases, and a decrease in mental capacity. Ways to increase the level of knowledge of practical nutrition of higher school students and ways to solve the problem of balanced nutrition of students as an effective condition for improving their health as an effective condition for improving their health It was established that one of the priority tasks today is to increase the level of education of student youth on healthy nutrition.

Reliable vehicle start is necessary to support mission success, especially for response time. At Department of Defense installations in cold regions, vehicles using rechargeable battery and starter technologies have significant issues starting in the cold. Ultracapacitor engine start modules (ESMs) are an alternate technology to rechargeable lead-acid or lithium-ion batteries. The project develops a performance baseline for the ESM used in the M1126 Stryker Combat Vehicle under cold conditions. To test the performance of the ESMs in a cold room, a mechanical load system was constructed to replicate the load of starting a Stryker engine and instrumented with sensors to monitor parameters such as voltage, torque, and temperature. The ESMs were tested with the load system at temperatures from 24°C to −40°C. The results of the tests showed that there was some degradation of the ultracapacitor’s performance at the colder temperatures, which was expected, but no permanent damage. This work provides a test protocol and capability to evaluate next-generation vehicle battery systems for cold regions applications. Additionally, the ESM cold performance data establish a baseline to compare next-generation vehicle battery storage systems and to support cold regions missions and identify potential performance requirements for future vehicle battery system acquisition.
