¿Medir el pH del suelo en la mezcla suelo: agua en reposo o agitando?
Authors: Beretta Andrés , Bassahum Daniel , Musselli Raquel
Published: February 2021

En la determinación del pH en suelo hay que considerar el tiempo de lectura y si realizar las medidas en reposo o agitando la mezcla suelo:agua . Este estudio comparó la medición de pH en el sobrenadante de la mezcla suelo:agua (1:2,5) luego de 15 minutos de reposo, con la alternativa de medir durante la agitación y en menor tiempo. Los procedimientos de medición de pH fueron: i) 3 minutos de agitación + 15 minutos de reposo y medición en el sobrenadante sin agitar (protocolo del laboratorio de INIA La Estanzuela); ii) lo mismo con medición en agitación de la mezcla durante 1, 2 y 3 minutos luego del reposo; iii) medición con agitación de la mezcla durante 1, 2 y 3 minutos sin reposo previo. Los valores de pH durante la agitación inicial fueron superiores a los del sobrenadante luego del reposo. Estas diferencias disminuyeron de 5,38 % a 3,91 % con tres minutos de agitación. No hubo diferencias en el valor de pH a los tres minutos de agitación con o sin reposo previo de 15 minutos. Las lecturas durante la agitación inicial de tres minutos, con tres repeticiones por muestra, presentaron un CV= 1,41 %. Medir el pH a los tres minutos de agitación sería una medición precisa y con una exactitud aceptable.

Las primeras evaluaciones del Proyecto Ovejas Prolíficas del Instituto Nacional de Investigación Agropecuaria (INIA, 2008- 2011) muestran que las madres cruza Frisona Milchschaf x Corriedale y Finnish Landrace x Corriedale destetan 60 % más corderos que la madre Corriedale pura, mientras que la madre cruza Finnish Landrace x Frisona Milchschaf desteta 85 % más que la madre Corriedale pura. Para recabar información respecto a la edad con que se inicia la pubertad, la estación de cría y tasa ovulatoria de estos nuevos biotipos se realizó un experimento con 87 corderas nacidas en la primavera 2010. Se utilizaron dos razas puras: Corriedale (C.C) y Frisona Milchschaf (M.M) y las siguientes cruzas: Finnish Landrace x Corriedale (F.C), Frisona Milchschaf x Corriedale (M.C), 3 / 4 Frisona Milchschaf - 1 / 4 Finnish Landrace (M.(F.M)), 7 / 8 Finnish Landrace - 1 / 8 Corriedale (F.(FxF.C)). Las corderas con más de 75 % de sangre Frisona Milchschaf (M.M y M.(F.M)) presentaron los mayores porcentajes de inicio de pubertad en su primer año de vida (>90 %). La estación de cría de estos dos biotipos fue la más amplia con una tasa ovulatoria de 1,0. Las corderas F.(FxF.C) siguieron a las anteriores en el porcentaje que alcanzó la pubertad y en la amplitud de la estacionalidad con una tasa ovulatoria 1,5. La estación de cría como borregas fue similar para todos los biotipos destacándose la alta tasa ovulatoria de las cruzas Finn (1,9-2,8) seguidas de Frisona Milchschaf (1,5-1,8) y de Corriedale (1.3).

Published: February 2021

Introduction: The presence of pancreatic tissue that lacks anatomical or vascular communication with the
pancreatic organ has a frequency in autopsy studies that ranges between 0.5% and 13.7%. It is most
commonly found in the stomach, specifically in the antrum. Treatment is not clearly established. Surgical
resection is recommended in symptomatic patients whose only cause of symptoms is ectopic pancreatic
tissue or cancerous formations.
Objective: Report a case of ectopic pancreatic adenoma given its low incidence.
Case Report: This study reports the case of a 45-year-old male with a history of clinical diagnosis of
gastroesophageal reflux disease and a Nissen fundoplication. He presented poor evolution 6 months after
the surgery. An endoscopy which revealed postpyloric “polyp” at the level of the duodenal bulb and an
inconclusive histopathological study of the same were performed. Reassessment with CT showed a tumor
in the first portion of the duodenum measured at 2.2cm, without adenopathies, and a normal-appearing
pancreas. It has been made a subtotal gastrectomy and Roux “Y” reconstruction, without complications,
with good postoperative evolution, discharged at home on the sixth day. With hematoxylin and eosin
technique, the histopathology report reported bile duct adenoma originating in ectopic pancreatic tissue,
positive immunohistochemistry for cytokeratin 7 (IHC-7), predominantly expressed by ductal epithelial
cells of the pancreatobiliary tract. The patient after surgery had a good clinical evolution and disappearance
of symptoms.
Conclusion: The clinical cases of rare pathologies are presented to increase the world bibliography and to
be able to compare the diagnosis and treatment. In this case, a heterotopic pancreatic adenoma was
presented, which is a diagnostic challenge.

Introduction
Authors: Wilhelm Cornelia
Published: February 2021

During the night of 9 November 1938, the persecution of the Jewish communities in Germany reached a new level with the systematic and physical destruction of property, the elimination of intellectual and business leadership, and the demolition of safe havens such as community and synagogue buildings, as well as the aid networks that spun around the synagogue. The atrocities not only destroyed important communal spaces and strongholds for Jewish communities, but also targeted German Jewry’s spiritual leadership, including rabbis and other functionaries around the synagogue such as cantors, a group whose fate during these days has hence found little attention in the research into these events.
German Refugee Rabbis in the United States and the Formation of ‘the Last Generation of the German Rabbinate’
Authors: Wilhelm Cornelia
Published: February 2021

This article uses an innovative digital humanities database and generational history in order to analyse the lives and careers of German refugee rabbis in the United States. It identifies the cohort among the refugee rabbis who were part of a communitisation process and defined themselves as ‘the last generation of the German rabbinate’, and illuminates how and why they could continue their careers in the United States better than elsewhere. It also examines their late returns to the country of their birth and analyses how they made sense of their own history by exchanges with the Germans. This was part of the transnational knowledge transfer that presented them as the last rabbis in the German-Jewish tradition, but also allowed them to successfully relaunch the establishment of modern Jewish seminaries for rabbinical training on the European continent and achieve symbolic continuity, eighty years after their destruction by Nazism.
Isaiah Berlin and the Animal Instinct
Authors: Delany Paul
Published: February 2021

Between Aristotle and Hegel, none of the major Western philosophers were married. Is abstract thinking, at its highest, incompatible with the messiness of everyday life? At the age of nineteen, Isaiah Berlin said he was ‘vowed to eternal celibacy’. Was there a connection between his sexual abstinence and his choice of analytical philosophy as a career? During World War II he fell in love with the gentile Patricia de Bendern; this frustrating affair coincided with Berlin’s shift from abstract logic to the history of ideas. In 1956 he took a Jewish bride, Aline Halban. His personal history reflects difficulties in choosing between endogamy and exogamy, Zionism and the diaspora, negative and positive liberty.
Rabbi Andre Ungar z’l
Authors: Magonet Jonathan
Published: February 2021

Rabbi Ungar was born in Budapest to Bela and Frederika Ungar. The family lived in hiding with false identity papers from 1944 under the German occupation. After the war, a scholarship brought him to the UK where he studied at Jews’ College, then part of University College, and subsequently studied philosophy. Feeling uncomfortable within Orthodoxy, he met with Rabbi Harold Reinhart and Rabbi Leo Baeck and eventually became an assistant rabbi at West London Synagogue. In 1954 he obtained his doctorate in philosophy and was ordained as a rabbi through a programme that preceded the formal creation of Leo Baeck College in 1956. In 1955 he was appointed as rabbi at the progressive congregation in Port Elizabeth, South Africa. Very soon his fiery anti-Apartheid sermons were condemned in the Afrikaans newspapers and received mixed reactions from the Jewish community. In December 1956 he was served with a deportation order and was forced to leave the country.

One of important properties of the industrial radiographic films defining clearness of the received image, ‒ granularity. In specifications on any industrial radio graphic film the manufacturer besides other characteristics: radiation sensitivity, contrast, is obliged to give the information about granularity, and the firms which are carrying out tests of radio graphic films, should spend its estimation. It is demanded by the international standard ISO 11699-1:2008. The size granularity, among other characteristics defines an accessory of a radiographic film to a certain class, and, hence, possibility of its use for x-ray or gamma control of those or other objects. For an estimation granularity the specific equipment and observance of technology of this process regulated ISO 11699-1:2008 is necessary. In article the information on an estimation granularity by means of the developed stand with breadboard models of optical system and data gathering system in automatic and manual modes is resulted. The developed stand has been used for an estimation granularity radiographic film D5 (Agfa). The received experimental data within admissible disorder coincide with the data specified in the certificate of conformity to the international standards.

Published: February 2021

Pedagogical control is one of the components of the teacher's practical activity, which reveals the advantages and disadvantages of new teaching methods. It allows you to match the planned and achieved level of knowledge, to evaluate student achievement, to identify gaps in his knowledge and skills. The forms and methods of pedagogical control are quite diverse. Currently, testing is increasingly used in the practice of school assessment. Testing process has more advantages than classical methods of knowledge control because it is the most objective way of knowledge assessing. Objectivity of testing achieves by standardizing the process and by minimizing the subjective component of student knowledges assessment. The mentioned advantages of the testing control form became the basis for the test system of the External Independent Еvaluation while entering higher education institutions.

It is advisable to introduce such a method of knowledge control as testing in the form of External Independent Еvaluation into the practice of school education for the gradual adaptation of the student to the form of testing that they will expect while entering the higher education institutions, as well as to reduce the negative psychological impact of the testing procedure on the student.

To achieve this goal, eight sets of test assignments have been created on different topics of the program for 11th grade students who study chemistry at the profile level. The test tasks are designed in the format of External Independent Еvaluation. The methodological materials that have been created can be used for the current and final control of the knowledges in the practice of General Secondary Education, like any other instruments of student knowledges control. As a result of the pedagogical experiment, it was found that testing in the External Independent Evaluation format, was more successful and effective to students with higher levels of education, since the total percentage of good and excellent grades obtained by students at testing was higher than in writing classic control work. The main disadvantages and advantages of using the test system for monitoring the quality and success of knowledge acquisition by students of the institution of general secondary education are presented.

Published: February 2021

The crystalline CsPbBr3 was synthesized from CsBr (6N) and PbBr2 (5N) by the mechanochemical method with further fusion in quartz ampoule at 640-650 °С. After synthesis, the structure and chemical composition of the obtained material was confirmed by energy-dispersive X-ray spectroscopy (EDX) and X-ray diffraction analysis. The melting and crystallization of the obtained perovskite were investigated by the differential thermal analysis (DTA) with heating/cooling rates of 1, 5 and 10 °C/min. Measurements were carried on the self-constructed DTA-setup with S-type thermocouples in the range of 450-590 °C. Each cycle of heating/cooling was repeated three times to confirm the accuracy of the results obtained. A decrease in the melting point from ~ 568.1 °C to ~ 566.2 °C was demonstrated with an increase in the heating rate from 1 °C/min. up to 10 °C/min. respectively. Probably, it's due to the approach to equilibrium conditions of phase transformations at lower heating rates. We recorded an additional-endothermic effect during CsPbBr3 melting. This may indicate a complex process of melting the compound. The thesis of a two-stage melting mechanism of CsPbBr3 perovskite with an initial stage of fragmentation of the crystalline structure and subsequent dissolution of crystalline phase residues is proposed. It is reported that with increasing of the melt heating above a certain "critical" temperature (579-585 °C), its homogenization occurs, and the crystallization temperature is set at 540-550 °C for the heating/cooling rate of 1 ° C/min. and 538-543 °C for the rate of 5-10° C/min. All obtained data confirm the assumption of a two-step melting process of CsPbBr3 perovskite, and the relatively constant crystallization temperature after a critical point of overheating may also indicate a certain structure of the melt of the compound with short-range order in the arrangement of the structural units of the compound in the liquid phase.

Published: February 2021

In the processes of free-radical oxidation of organic compounds, the inhibitory action of the inhibitor is mainly due to either the breakdown of the reaction chains on its molecules, or the slowdown of the decomposition of intermediate hydroperoxides, or both at the same time. We analysed the inhibitory properties of 4-[3,5-di(tert-butyl)-4-hydroxyphenyl]-5-ethoxycarbonyl-6-methyl-3,4-dihydropyrimidin-2-one (I) and 4-[4-methoxyphenyl]-5-ethoxycarbonyl-6-methyl-3,4-dihydropyrimidin-2-one (II) gasometry and hydroperoxide decomposition methods. These compounds were obtained by the three-component Biginelli reaction. The decomposition of cumene hydroperoxide in dimethylformamide under these conditions is described by a first-order kinetics equation. The first compound significantly inhibits the decomposition of hydroperoxide. The dependence of the effective rate constant of the decomposition of cumene hydroperoxide on the first concentration is described by the equation: . The second compound also slows the decomposition of hydroperoxide, but much less than the first compound. Therefore, both the phenolic moiety and the urea moiety of the dihydropyrimidinone cycle take part in slowing the cumene hydroperoxide decomposition. Initiated oxidation of cumene happened at 343 K with the presence of the initiator azodiisobutyronitrile. The concentration of the first compound varied from 1,5·10-4 to 2,5·10-3 mol/l. With a concentration of the first compound 1,25·10-3 and 2,5·10-3 mol/l, the duration of the induction period exceeds 80 min. In the concentration range (1,5÷6,3)·10-4 mol/l the linear change in the duration of the induction period is observed. 4-[3,5-Di(tert-butyl)-4-hydroxyphenyl]-5-aminocarbonyl-6-methyl-3,4-dihydropyrimidin-2-one is a more effective inhibitor than the ionol due to the urea moiety of the dihydropyrimidinone cycle. Confirmation is the notable antioxidant activity of the second compound. In conclusion, 4- [3,5-di (tert-butyl)-4-hydroxyphenyl]-5-ethoxycarbonyl-6-methyl-3,4-dihydropyrimidin-2-one is a bifunctional inhibitor.

Published: February 2021

The influence of the structure of a number of merocyanine dyes (D), which differ in the length of the polyethylene chain on one vinyl group, on their spectral, electrochemical and energy characteristics is established. Cyclic voltammetry determines their oxidation and reduction potentials. The values ​​of the HOMO and LUMO energy levels of the studied dyes from spectral and electrochemical data were calculated. It is shown that the obtained values ​​of the potentials of the energy levels of the dyes differ little (the energy difference ranges from 0,22–0,53 eV). The possibility of using merocyanins as sensitizers of titanium(IV) oxide and the creation of photosensitive heterostructures has been made. In order to investigate the possibility of using the merocyanin dyes under study as TiO2 sensitizers, the energy of the «semiconductor – dye – reagents» systems was considered. For this purpose, we compared the redox characteristics of merocyanine dyes with the electrophysical parameters of titanium(IV) oxide, as well as the redox characteristics of the reaction participants. It is established that in such systems the processes of photon transfer of the electron from the dye to the semiconductor are necessary for sensitization, and the regeneration of the original form of the sensitizers by the action of the reducing agent on the cation radicals formed is thermodynamically allowed. The conclusion about the possibility of using the studied merocyanines as effective sensitizers was confirmed by the results of the study of the photocatalytic activity of D/TiO2 heterostructures in the reaction of methylene blue formaldehyde recovery under different irradiation conditions and at different dye concentrations. The explanation for the found laws is offered. Scientific approaches to the production of new photosensitive systems with an expanded range of photosensitivity and a given level of photocatalytic activity have been developed.

Este artigo discute o Governo Bolsonaro, a crise política e as narrativas sobre a pandemia. Pretende uma análise da atual conjuntura brasileira que vivencia duas crises: a crise política e a crise sanitária. O governo brasileiro de forma deliberada não enfrenta a pandemia do novo coronavírus e com isso, amplia o número de infectados que ultrapassa 2 milhões, empurrando o país para a maior tragédia da saúde pública de sua história com mais de 100 mil mortes, um genocídio presenciado por todo o mundo. O texto trata, também, as diversas narrativas sobre a pandemia, as narrativas do presidente Bolsonaro e seus seguidores, as narrativas que confrontam vidas e empregos (economia e saúde), as narrativas que criam um inimigo externo causador da pandemia, as narrativas da charlatanice religiosa que vende curas milagrosas e  a narrativa do “Fique  em Casa”. Todo esse contexto político/pandêmico fragiliza a oposição ao governo que seque forças para emplacar um processo de impeachment. Estas são as questões discutidas neste texto.

Ethiopia: The Environmental Aspects of Policy and Practice in the Ethiopian Floriculture Industry
Authors: Mengistie Belay Tizazu
Published: February 2021

The floriculture sector is booming in Ethiopia, making the country the second largest flower exporter in Africa and one of the largest suppliers of flowers globally. Despite the enormous advantages of the Ethiopian floriculture industry to the country’s economy, the industry’s unsustainability related to environmental and human rights is growing. Failure to protect the environment can have profound negative impacts on long-term economic development and human rights, including the right to life, adequate food, water and housing. The floriculture industry has been identified as having the potential to grow and contribute positively to the agricultural transformation and economy of Ethiopia. Policy, laws and regulations play a vital role in the implementation of any regulatory objective. During the last decade, Ethiopia has developed many policies and laws that link to improving the environment, and the flower farm industry itself has adopted self-regulation and standards, enhancing the protection of workers and the environment. But there is increasing evidence that the economic benefits of the flower industry come at the expense of the environment. So, what is the impact of these State and non-State regulations on a safe and clean environment? This paper aims to analyse how, why and under what circumstances environmental policy implementation might work or fail, by investigating the challenges for the floriculture industry relating to the intensive use of pesticides and water, and inappropriate waste disposal in the policy implementation process. It is safe to say that Ethiopia has developed a lot of legislation on the environment but the challenge of effective monitoring and enforcement remains. This paper concludes with recommendations, based on the fact that the principles of environmental rights, the right to life and the right to development cannot be realised in the absence of the right to a healthy environment.

Authors: Malik Hasmat , Almutairi Abdulaziz , Alotaibi Majed A.
Published: February 2021

In the modern electrical power system network (EPSN), the power quality disturbances (PSDs) are the serious issue for the power engineer to maintain the uninterrupted and reliable power supply. Generally, PQDs are generated due to non-linear loading conditions, perturb loading and other occurrences such as transient, harmonics, sag, swell and interruptions. These problems of PQDs effect the power demand mapping problem, which effect the reliability and stability of the EPSN operating condition. In this study, a novel approach for PQDs diagnosis (PQDD) is proposed, which includes real-time data generation, data pre-processing, feature extraction, feature selection, intelligent model development for PQDD. Data decomposition approach of EMD is utilized to generate the feature vector of IMFs. These features are utilized as an input variables to the intelligent classifiers. In this study, PQDD is analyzed based on SVM method and obtained results are compared with conventional AI method of LVQ-NN. The results represent the higher acceptability of the proposed approach with diagnosis accuracy of 99.98% (training phase), 93.11% (testing phase) for SVM and 92.56% (training phase) and 91.0% (testing phase) for LVQ-NN based PQDD method.

Authors: Sharma Ajit Kumar , Bhushan Bharat
Published: February 2021

The present work represents the implementation of the various fuzzy controller with robust sliding mode control (SMC) technique on a nonlinear system considering various external disturbances and model uncertainties. The nonlinear system considered here is a single link inverted pendulum. The proposed work combines the advantages of the sliding mode controlling technique and fuzzy logic controller. A set of linguistic rules are designed in fuzzy logic control, which causes the system to be chattering free. Parameters of the nonlinear system are adjusted according to fuzzy adaptive laws, while the uncertainties of the nonlinear system have been approximated using a fuzzy system. Various types of controller based on fuzzy sliding mode, like approximation based sliding mode control technique; equivalent control based fuzzy sliding mode technique, and switch-gain regulation based sliding mode control methods have been implemented here. A comparative analysis of various methods is also have been discussed.

The purpose of this study was to examine the relationship of relationship benefit and commitment in developing customer loyalty first and then to develop the intelligent model to predict the customer loyalty. Survey methodology was used to gather data from three different service sectors based on the classification by Bowen. A sample of 600 customers and responses were collected randomly from the front desk of services. Regression analysis by Using SPSS 20 was applied to analyze the data collected. The findings of the study revealed that relationship benefit and commitment had direct positive influence on customer loyalty. Furthermore the commitment of customer towards an organization is instrumental in developing loyalty. After performing the advance data analytics, ANN model was developed to predict the loyalty, which can be utilized to prepare the further directions and road map for service industry. Obtained results reveals that proposed machine intelligence approach is very useful for service industry for short-term as well long-term future planning.
Multiple strategies for supply chain to recover from major disruptions
Authors: Shi Honghua , Ni Yaodong
Published: February 2021

Today’s supply chains have a greater likelihood of disruption risks than ever before. Sometimes, a lengthy recovery period is needed for supply chains to return to regular operation after being disrupted. During the recovery time window, how to increase the performance of supply chains is not sufficiently studied. Furthermore, the works considering parameter uncertainty arising from the lack of historical data are also limited. To address these problems, we formulate the recovery scheduling of supply chains under major disruption as mixed-integer linear programming models. In the presented models, outsourcing strategy and capacity expansion strategy are introduced to increase the service level of the supply chain after the disruption. The effects of disruption risks on supply chain performance are quantified using uncertainty theory in the absence of historical data. A set of computational examples illustrate that cost may increase markedly when more facilities are disrupted simultaneously. Thus, decision-makers have to pay close attention to supply chain disruption management and plan for disruption in advance. Moreover, the results suggest that outsourcing strategy is more useful to reduce cost when a higher service level is required.

Background: This study investigates work-related musculoskeletal disorders risk estimation by frequently as used as ergonomic methods in the field. Objective: To identify the difference in risk estimation by an in-house observational method and a self-reported questionnaire, and to evaluate the complementary aspects of these methods. Methods: A sample of 15 operators who worked on the assembly workstations was selected from a truck manufacturing plant. The risk assessment of these workstations (28 scenarios) was performed by the observational method and the self-reported questionnaire. The agreement between both methods to identify risk situations was measured with the weighted Kappa coefficient. Results: The observational method and the self-reported questionnaire deployed on the same activity estimated different risk situations. Conclusion: This analysis does not reveal that one tool is more powerful than the other one, but shows the probability of different risk estimation. The complementary effect of each method might be considered for further investigation concerning musculoskeletal risk factors.
Self-control and organizational citizenship behavior: The role of vocational delay of gratification and job satisfaction
Authors: Liu Yao-Zhong , Wang Yu-Jie
Published: February 2021

BACKGROUND: Self-control is an important factor in predicting employees’ organizational citizenship behavior, but previous studies have not examined the internal mechanism by which self-control affects organizational citizenship behavior. OBJECTIVE: The current study aimed to explore the relationship between self-control and employees’ organizational citizenship behavior and to test the mediating effects of vocational delay of gratification and job satisfaction. METHODS: Participants were 474 full-time employees (187 male, 287 female) from different companies in South China. They answered online self-report questionnaires that assessed self-control, vocational delay of gratification, job satisfaction, and organizational citizenship behavior. Path analyses were conducted and a bootstrap technique was used to judge the significance of the mediation. RESULTS: The results showed that high self-control employees were more willing to engage in citizenship behavior that benefitted their organizations and colleagues, and the chain mediating effect of vocational delay of gratification and job satisfaction between self-control and organizational citizenship behavior was significant. CONCLUSIONS: These findings provide insights to management regarding the mechanism to promote and maintain employees’ pro-organizational behavior.
