Cumaná y Bartolomé de las Casas: el aristotelismo en el Nuevo Mundo
Authors: Ambrosi De la Cadena Marco 
Published: April 2024

Resumen El artículo revisa el proyecto de Cumaná elaborado por Bartolomé de las Casas en 1518 para la evangelización pacífica de los habitantes de la región de Paria. El objetivo es evidenciar la aplicación conveniente del aristotelismo en dicha propuesta para conciliar la conversión cristiana de los indios con la legitimación del rey en tierra firme. Para este fin, se repasa el contexto histórico de la propuesta de Cumaná y la disputa entre Juan de Quevedo y Las Casas en 1519, previo a su aprobación, como una de las primeras ocasiones en que se recurre al Estagirita para tratar la situación del Nuevo Mundo. Igualmente, se sugiere la interpretación del proyecto lascasiano considerando la teoría política de Aristóteles en aspectos como: definición de la conversión como fin político, relación del indio con el español, condición política del indio, la posible república indiana y la potencialidad pasiva del indio. En conclusión, Cumaná representa un desafío al marco teórico-político de la época, al emplear la prédica pacífica como estrategia para legitimar el dominio español entre los indios y como alternativa a la conquista violenta. Abstract The paper revises the evangelization project of Cumaná made by Bartolomé de las Casas in 1518 for the peoples of the Paria region, it aims at highlighting his convenient application of Aristotelianism to harmonise the Christian conversion of Indians with the King legitimisation in tierra firme. The historical context of the Cumaná initiative and the dispute for its approval between Juan de Quevedo and Las Casas in 1519 are reviewed regarding the use of Aristotelian concepts probably for the first in a formal discussion about the New World. Also, the article suggests interpreting the Lascasian project from the political theory of Aristotle in several aspects such as conversion as a political end, relationship among Spaniards and Indians, political condition of Indians, a possible Indian republic, and the Indian passive potentiality. In conclusion, Cumaná challenges the theoretical-political framework of its time, by employing pacific preaching as a strategy to legitimise the Spanish dominion among the indios, and as an alternative to violent conquest.

For this, it will seek to contextualize the life of the Jesuit dedicated to the Thomasian doctrine, both in the New Kingdom of Granada and in Spain. From this, the intellectual foundations of Ripalda’s thought will be sought; in this logic, not only the notions of Aquinas will be present, but also some philosophical traces from the century 17, which, although subtle, tend to address the reflection of being in the horizon of knowing. In order to reach the highlighted objective, the book Vida, Obra y Pensamiento del maestro javeriano Juan Martínez de Ripalda will be used as a reference, a composition made by Germán Marquínez and José del Rey. Finally, it is intended with this to bring considerations that may come to assist research in colonial scholasticism.
Development of briquette modifier composition to increase the stability of grinding media in iron ore fine grinding mills
Authors: Suslo Nataliia , Huk Yelyzaveta , Panchenko Hanna 
Published: April 2024

Recently, there has been a trend towards the use of modifiers in the form of briquettes produced by pressing highly dispersed materials with a binder. The choice of a rational composition of the briquette-modifier will improve the properties of cast irons and steels by increasing the assimilation of the modifying components and facilitating their introduction into the melt. Therefore, the possibility of using briquetted materials for modifying and alloying cast iron to improve melt quality, considered in this paper, is relevant. A literature analysis was carried out on the methods of producing briquettes. The influence of the main technological parameters of briquettes production on their quality characteristics is studied. It was found that the main limitation of the use of briquette modifiers is their high dissolution temperature (more than 1450 °C). The paper considers the possibility of reducing the briquette dissolution temperature by introducing the magnesium-aluminium alloy MAGR into its composition, which helps to accelerate the dissolution due to the internal rupture of the briquette from thermal shock. The rational composition of the modifier, which includes nanodispersed titanium carbonitride powder (35-40%), granular MAGR alloy (5-10%) and dispersed cast iron chips (the rest), was determined by laboratory tests. The proposed composition of the briquettes is appropriate in terms of the optimum dissolution temperature (12500C) and increasing the rate of interaction of the briquette reagents with the melt. The experimental briquette modifiers were tested in industrial conditions at PJSC ArcelorMittal Kryvyi Rih. According to the results of the research, it was found that the use of the developed briquette-modifier in the manufacture of cast iron grinding balls increases their operational stability by 18-30%, which made it possible to reduce the cost of ore grinding.

Published: April 2024

Aim: The study investigates the impact of floods on farm income and livelihoods of farmers in Bagalkot district of Karnataka, focusing on the years 2019 and 2020.
Study Design: Multi stage purposive sampling technique was adopted to collect the data.
Place and Duration of Study: Bagalkot district of Northern Karnataka was selected for the study.
Methodology: The study is based on primary data collected from 90 respondents belonging to Ghataprabha and Krishna river basin in Mudhol (45) and Jamakhandi (45) taluks. Descriptive statistics is used to analyses the data.
Results: The results revealed substantial losses in farm infrastructure, including residences, farm buildings, pump houses, and cattle sheds, with significant financial implications. During 2019, the average loss incurred by the sample households from all the sources was Rs. 8,55,540 against which Rs. 99,222 was paid as compensation by the Government which accounts for 11.59 per cent of the total loss. Similarly, during 2020, the average loss incurred by the respondents was Rs. 4,05,373 against which only Rs. 41,277 was paid as compensation from the state Government which accounts for 10.18 per cent of the total loss. Moreover, floods led to on-farm and off-farm income losses, with severe implications for livelihoods. Coping mechanisms employed by farmers included selling farm produce, livestock, and valuable assets, as well as borrowing credit from various sources.
Conclusion: The compensation given by the government is very less as compared to loss incurred. On time release of compensation is required to coping with disaster. The persistent challenges faced by farmers in mitigating the impacts of floods on their livelihoods. Therefore, there is need for a separate disaster management policy especially for northern districts of Karnataka which faces severe flooding during monsoon period.

AbstractCell micropatterning, a method to place cells at arbitrary regions, is becoming an essential tool to conduct cell biology and tissue engineering. Conventional cell patterning techniques usually allow only single patterning with single cell type on the same culture surface. However, biomedical research today requires even sophisticated fabrication methods that require spatiotemporal control of multiple cell arrangements. Here we introduce in situ cell micropatterning system which enables stepwise cell patterning using a photoresponsive cell culture surface (PRCS) whose cell adhesiveness could be altered by the UV irradiation. To demonstrate an application to tissue engineering, a liver‐mimic tissue array was fabricated and liver‐specific gene expressions were quantified with real time PCR. Patterned co‐culture systems composed of HepG2 spheroids with Balb/3T3 were fabricated, and the optimum spheroid diameter, which yielded the highest cellular functions, was determined to be 150 µm. After 20 days of patterned co‐culture of HepG2 spheroids and Balb/3T3, CYP3A4 expression increased 50‐fold higher than conventionally cultured HepG2; CYP3A4 expression was 20% higher than randomly co‐cultured HepG2 and Balb/3T3. Thus the combination of PRCS and the photomask‐free irradiation apparatus showed the versatility of experimental setups and proved to be a powerful tool for biomedical studies. Biotechnol.

Published: January 2009

AbstractWe demonstrate selective retention and positioning of cells or other bioparticles by ultrasonic manipulation in a microfluidic expansion chamber during microfluidic perfusion. The chamber is designed as a confocal ultrasonic resonator for maximum confinement of the ultrasonic force field at the chamber center, where the cells are trapped. We investigate the resonant modes in the expansion chamber and its connecting inlet channel by theoretical modeling and experimental verification during no‐flow conditions. Furthermore, by triple‐frequency ultrasonic actuation during continuous microfluidic sample feeding, a set of several manipulation functions performed in series is demonstrated: sample bypass—injection—aggregation and retention—positioning. Finally, we demonstrate transillumination microscopy imaging of ultrasonically trapped COS‐7 cell aggregates. Biotechnol. Bioeng. 2009;103: 323–328. © 2009 Wiley Periodicals, Inc.

Mutual impedance of non‐parallel conductors with earth return
Authors: Budnik K. , Machczyński W. 
Published: January 2009

AbstractThe calculation of currents and potentials along underground conductors (telecommunication and power cables, pipelines) occurs in many practical problems associated with interference from currents in power transmission lines or electrified railways lines. The knowledge of the mutual impedance between both earth‐return circuits is essential in case of inductive influence. The mutual impedances of long conductors may be derived using the Carson method. The formulas, however, apply only to parallel conductors. In case of non‐parallel conductors an approximation method overcomes this problem by segmenting the angled conductor along its length. In the paper the alternative approach is proposed, based on the linearization of the mutual impedance characteristic for 50 Hz. The use of the linear regression method leads to accurate results of calculation of potentials excited by the inductive effects of a transmission line on non‐parallel underground conductor.In the paper the method of determination of the mutual impedance of angled conductors with earth return is also developed for the case when one of the conductors is finite in the length. The formula for the mutual impedance contains an integral, which does not have an analytical solution. A numerical integration algorithm is developed. The exemplary calculations show that the use of the algorithm developed leads to results with considerably accuracy. Copyright © 2009 John Wiley & Sons, Ltd.

Published: January 2009

AbstractQuantitative structure–property relationship (QSPR) investigation was performed for the study of olfactory thresholds of pyrazine derivatives. Descriptors calculated from the molecular structures alone were used to represent the characteristics of the compounds. The six molecular descriptors selected by the best mutilinear regression (BMLR) in CODESSA were used as inputs for support vector machine (SVM) and radial basis function neural networks (RNFNN). The root mean squared errors (RMS) of logarithm of olfactory thresholds (p.p.m.) for the training, predicted and overall datasets were 0.5674, 0.6601 and 0.5860 for BMLR, 0.4720, 0.6861 and 0.5194 for RBFNN, and 0.5242, 0.6466 and 0.5495 for SVM, respectively. The prediction results were in agreement with the experimental values. The QSPR models provide a rapid, simple and valid way to predict the odour threshold of pyrazine derivatives.

The proteolytic activity of insulin‐degrading enzyme: a mass spectrometry study
Authors: Grasso Giuseppe , Rizzarelli Enrico , Spoto Giuseppe 
Published: January 2009

AbstractThe prominent role that insulin‐degrading enzyme (IDE) has on amyloidogenic peptides degradation has recently boosted a lot of attention toward this enzyme. Although many substrates are known to be degraded by IDE, little is known about the changes in the proteolytic activity of the enzyme upon modification of environmental factors.In a previous work we have already shown the great potentiality of atmospheric pressure/laser desorption ionization‐mass spectrometry (AP/MALDI‐MS) for studying the interaction between IDE and insulin. Here, the activity of IDE was investigated regarding cleavage sites' preferentiality upon modification of environmental factors by AP/MALDI‐MS. The roles that IDE/insulin concentration ratio, reaction time, adenosine 5′‐triphosphate (ATP) and metal ions (Zn and Cu) have on the insulin cleavage pattern produced by IDE are investigated and a plausible interpretation involving the proteolytic action of the different IDE oligomeric forms is proposed.

Published: January 2009

AbstractBACKGROUND:Douchi, a traditional fermented soybean food, has recently attracted a great deal of attention owing to its superior physiological activity. In the present study the angiotensin I‐converting enzyme (ACE)‐inhibitory activity of typicaldouchiprocured from various regions of China was analysed. An ACE‐inhibitory peptide derived from the most potentdouchiwas also isolated and characterised. The pattern of ACE inhibition and resistance to hydrolysis by gastrointestinal proteases of this peptide are described.RESULTS:ACE‐inhibitory activities were detected in alldouchisamples, with IC50values ranging from 0.204 to 2.011 mg mL−1. Among thedouchisamples, aMucor‐typedouchiexhibited the most potent ACE‐inhibitory activity (IC50= 0.204 mg mL−1). A novel ACE‐inhibitory peptide was then isolated from thisMucor‐typedouchiusing ultrafiltration followed by Sephadex G‐25 column chromatography and reverse phase high‐performance liquid chromatography. The amino acid sequence of the purified peptide was identified by Edman degradation as His‐Leu‐Pro (IC50= 2.37 µmol L−1). The peptide is a competitive inhibitor and maintained its inhibitory activity even after incubation with some gastrointestinal proteases.CONCLUSION:The present study shows that peptides derived from soybean fermentation duringdouchiprocessing could be the main contributor to the ACE‐inhibitory activity observed.

Suppressing One‐Bond Correlations in HMBC Spectra: Improved Performance for the BIRD–HMBC Pulse Sequence
Authors: Furrer Julien , Thévenet Damien 
Published: January 2009

AbstractAn improved version of the BIRD–HMBC experiment is proposed. In comparison to the original version, the filtering (suppression of 1 JCH signals) is accomplished using a double tuned G‐BIRD filter positioned in the middle of the long‐range correlations evolution period. Compensation of offset dependence by replacing the rectangular 180° pulses with the broadband inversion pulses (BIPs), with superior inversion performance and improved tolerance to B1 field inhomogeneity, significantly improves the sensitivity of the original BIRD–HMBC experiment. For usual one‐bond coupling constants ranges (115–180 Hz), optimal results are easily obtained by adjusting the delays, δ, of the BIRD elements to an average J value. For larger ranges (e.g. 110–260 Hz), the use of a double tuned G‐BIRD filter allows excellent suppression degrees for all types of one‐bond constants present in a molecule, superior to the original scheme and other purging schemes. These attributes make the improved version of the BIRD–HMBC experiment a valuable and robust tool for rapid spectral analysis and rapid checks of molecular skeletons with a minimum spectrometer time.

Published: January 2009

Abstract
A tight binding molecular dynamics calculation has been conducted to study the size and coordination dependence of bond length and bond energy of Pd atomic clusters of 1.2–5.4 nm in diameter. It has been found that the bond contraction associated with bond energy increases in the outermost layer about 0.24 nm in a radial way, yet in the core interior the bond length and the bond energy remain their corresponding bulk values. This surface bond contraction is independent of the particle size.
