Contribution of ESIFs to the digital society development in the EU
Authors: Kersan-Škabić Ines , Vukašina Martina
Published: July 2023

COVID-19 pandemic has accelerated the transition of EU economies toward a higher level of digital society development. The European Commission set digitalization as one of its most important priorities for 2019-2024. As both the Cohesion Policy and the Next Generation EU aim to support the realization of EC priorities, in this paper we focus on examining and evaluating the allocations from European Structural and Investment Funds (ESIFs) to the digital society performance. The research results subverted expectations, revealing that ESIFs spending on ICT does not contribute to the digital society development. This highlights the need for more investment into the ICT to reduce the gap in performances of the EU member states.

Published: July 2023

The purpose of the article is to determine development gaps and critical points in the system of business – education collaboration in R&D investment using MAR-splines. The study attempts to confirm hypotheses about the impact of business – education collaboration in R&D investment on the sustainable development, and, in turn, the influence of chosen factors on the level of cooperation of business and education in R&D investment taking into account development gaps and critical points. These factors include the values of gross domestic expenditure on R&D spent by the business enterprise sector and by the higher education sector, and the level of the informal economy. The study is based on the sample of the 10 countries leading the ranking of Sustainable Development Index for 2011-2018 (time limits are set due to the availability of all studied indicators in the statistical databases of the World Bank, UNDESA, OECD and WIPO). Critical points and knots are determined using MAR-splines and two-way median-spline plots in STATA software. It has been proven that the business – education collaboration in R&D investment contributes to increasing the level of sustainable development if the value of this indicator is in the range of critical points from 62.04 to 68.96 (1% growth increases the estimate of sustainable development by 0.7%). In turn, development gaps and critical points have also been found for factors influencing the level of business-education R&D collaboration.

Published: July 2023

Over the last two decades, the banking sector in Europe has undergone significant changes in terms of regulations and market structure, which resulted in a significant increase in M&A transactions. The rise of M&A activity was also a consequence of fundamental changes in the external environment, such as introduction of the euro, technological progress and changing customer demand. The aim of this contribution is to compare the impact of the integration of the countries in the European Monetary Union on the volume (value) and number of realized M&A. The Mann-Whitney U test was used to verify three individual hypotheses. The results of the analysis did not confirm differences in the volume and number of M&As between EMU and non-EMU countries (with the exception of 2 years).

Authors: Kumar Bishnoi Sushil , Guru Ramratan
Published: July 2023

The aim of the study was to analyse the impact of various consumer attributes on the fast fashion consumption pattern. The effect of consumer age, family income and family size on the percentage of monthly income spent on clothing and percentage of monthly clothing consumption spent on fast fashion by consumers in NCR (National Capital Region) of India was studied in this research. Causal research was employed in this study. Correlations among the variables were established using the response surface methodology (Box-Behnken experimental design) to understand whether the impact is significant or not. Control factors, studied at 3 levels of variation, were age, monthly family income and family size. The responses for the experiment were the percentage of monthly income (per person) spent on clothing and the percentage of monthly clothing consumption spent on fast fashion. The study revealed that age and monthly family income have a strong influence on the percentage of monthly income spent on clothing, while family size has a negligible or no effect on the percentage of monthly income spent on clothing. It was also found that age, monthly family income and family size have a strong influence on the percentage of monthly clothing consumption spent on fast fashion. The demand for fast fashion and clothing is rising at a very high rate, which has made it hard for retail brands and apparel manufacturers to meet the consumer expectations. The analysis of consumer behaviour provides the advantage to fashion brands in anticipating and meeting consumer demands in a more efficient manner to create brand loyalty.

Published: July 2023

Magnetite synthesis using petai (Parkia speciosa) peel extract using the sonochemical method (Fe3O4-PPE) has been successfully carried out. Fe3O4-PPE is applied as a catalyst in biodiesel production. This study aimed to determine the physical and chemical characteristics of Fe3O4-PPE and its ability as a reusable catalyst in biodiesel production using waste frying oil as the primary raw material. Characterization of Fe3O4-PPE was carried out using FTIR, XRD, and PSA instruments. Biodiesel was produced in 3 reaction cycles with the same Fe3O4-PPE catalyst. The results of the FTIR characterization showed that the Fe3O4-PPE catalyst had Fe-O bonds from Fe3O4 and -OH phenolic groups, -C-O, -C=C aromatic compounds derived from petai peel extract. The crystal size of the Fe3O4-PPE catalyst based on the results of calculations using Debye-Scherrer from the XRD chromatogram is 9.41 nm. The particle size of the Fe3O4-PPE catalyst based on analysis using PSA was divided into three groups, namely, 5.4 nm, 195 nm, and 2702.6 nm. Fe3O4-PPE was successfully used as a reusable catalyst for three cycles of biodiesel production using waste frying oil as raw material. The characteristics of Fe3O4-PPE before and after being used as a catalyst did not change. Based on GC-MS analysis, the fatty acid methyl ester (FAME) composition of biodiesel is palmitic acid and oleic acid.

Dye is one of the waste waters, which will be a problem if the content is excessive in the water. Modifying bentonite with titanium dioxide (TiO2) as a photocatalyst for removal of dye waste. In this study, composite synthesis was carried out by mixing bentonite and TiO2 suspensions. The mass of bentonite is 20 g, and the mass variations of TiO2 are 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, and 100%. The resulting composite was heated using a furnace at 550°C for 5 hours. Bentonite-TiO2 composites were characterized using Fourier Transform Infrared, X-Ray Diffraction, and Scanning Electron Microscope-Energy Dispersive X-Ray (SEM-EDX). Photodegradation of methylene blue dye with bentonite-TiO2 was carried out by varying the mass of bentonite-TiO2 photocatalysts (0.02, 0.04, 0.06, 0.08 g); variations in pH (1, 3, 5, 7, and 9), and variations in UV irradiation time (30, 60, 90, and 120 minutes). The results of characterization with FTIR showed the presence of Ti-O-Ti vibrations at wavenumber 1419 cm-1 and Si-O-Ti at wave numbers 780 cm-1 and 799 cm-1. Characterization of 20% bentonite-TiO2 by XRD showed rutile, anatase, and montmorillonite phases. The SEM-EDX bentonite-TiO2 characterization results produced some small particles with a layered structure with TiO2 particles clumping and still in the form of agglomerates, and the EDX results showed the chemical composition of Si and Ti. The results of photodegradation showed that the best activity for the bentonite-TiO2 composite occurred in photocatalyst BT-20% with a mass of 0.08 g, pH 1, and UV irradiation time of 120 minutes with methylene blue 99.942% degraded.

Experiencias traumáticas y síntomas psicopatológicos en población penitenciaria y población general
Authors: Molina Coloma Verónica Alexandra , Reyes Sosa Hiram
Published: July 2023

Los eventos traumáticos son hechos estresantes que exceden los recursos de afrontamiento de un individuo y han sido relacionados con problemas de salud física y mental, particularmente con el trastorno de estrés postraumático. El objetivo de este estudio es comparar las experiencias traumáticas y los síntomas psicopatológicos entre la población penitenciaria y la población general. Es un estudio descriptivo-comparativo de corte transversal. La muestra del estudio estuvo conformada por 99 individuos encarcelados y 84 individuos de la población general de Ambato (Ecuador). Los resultados indican que los participantes de la población penitenciaria han experimentado en mayor medida múltiples traumas y revictimización; presentan un mayor número de síntomas psicopatológicos y un porcentaje más elevado de TEPT que la población general. Las diferencias que se presentan entre la población penitenciaria y la población general pueden deberse a que las personas encarceladas son más vulnerables a estar expuestas a eventos potencialmente traumáticos por su propia situación social. La población penitenciaria requiere una mayor intervención para reducir los síntomas psicopatológicos provocados por el trauma.

Published: July 2023

We introduce the notion of a wall-connected twin building and show that the local-to-global principle holds for these twin buildings. As each twin building satisfying Condition (co) (introduced in [7]) is wall-connected, we obtain a strengthening of the main result of [7] that covers also the thick irreducible affine twin buildings of rank at least 3.

Compact flexible actuator based on a shape memory alloy for shaping surgical instruments
Authors: Fischer Nikola , Mathis-Ullrich Franziska
Published: July 2023

Conventional flexible actuators for minimally invasive interventions come with complex and bulky actuation infrastructure. We present a proof-of-concept study of a compact flexible actuator with variable shape change featuring shape memory alloy wire loops in active-antagonist configurations for a bending and S-shape. The actuator was fabricated using heat-treated wire loops. The evaluation using optical marker tracking revealed a mean maximum absolute displacement at the distal tip of 19 mm and a force of 90 mN reached in under 15 s. For control, a closed-loop regime was evaluated with steady-state errors below 2°.
Shape-sensing by self-sensing of shape memory alloy instruments for minimal invasive surgery
Authors: Fischer Nikola , Knapp Johannes , Mathis-Ullrich Franziska
Published: July 2023

Shape memory alloy-based flexible instruments have potential for enhancing the safety in minimally invasive surgery compared to passive rigid devices. We developed a data-driven polynomial model to estimate deflection of a 2D bending actuator using electrical resistance. The model accurately predicts deflections (mean error <3.6 mm), but force sensing augmentation is required for unknown load cases. The model is specific to the tested actuator geometry, and future research should investigate multiple actuators and explore nonlinear modeling approaches.
Musculoskeletal model-based control strategy of an over-actuated glenohumeral simulator to assess joint biomechanics
Authors: Genter Jeremy , Rauter Georg , Müller Andreas M. , Mündermann Annegret , Baumgartner Daniel
Published: July 2023

Determining the acting shoulder and muscle forces in vivo is very complex. In this study, we developed a control strategy for a glenohumeral simulator for ex vivo experiments that can mimic physiological glenohumeral motion and overcome the problem of over-actuation. The system includes ten muscle portions actuated via cables to induce upper arm motion in three degrees of freedom, including scapula rotation. A real-time optimizer was implemented to handle the over-actuation of the glenohumeral joint while ensuring a minimum of muscle tension. The functionality of the real-time optimizer was also used to simulate different extents of rotator cuff tears. Joint reaction forces were consistent with in vivo measurements. These results demonstrate the feasibility and added value of implementing a real-time optimizer for using in vivo data to drive a shoulder simulator.

Berberine suppressed sarcopenia insulin resistance through SIRT1-mediated mitophagy
Authors: Su Xiaojuan , Yang Danqi , Hu Yu , Yuan Ying , Song Le
Published: July 2023

Abnormal mitochondrial function resulting in inadequate energy supply leads to sarcopenia and IR, suggesting that maintaining mitochondrial homeostasis by regulating mitophagy may be a promising strategy for sarcopenia IR therapy. Herein, we constructed sarcopenia mice model, which was treated with berberine and/or SIRT1/mitophagy inhibitors, and the activity of SIRT1/mitophagy signaling pathway was identified. Then, muscle tissue, blood biochemical index, inflammatory factors, GTT, and ITT were detected. We found that berberine treatment increased the body weight and alleviated d-galactose-induced weight loss in mice. SIRT1/mitophagy inhibitors suppressed the effects of berberine in the treatment of sarcopenia. The effect of berberine on the increase of muscle tissue, improving metabolic disorders, reducing the expression of inflammatory factors, and suppressing sarcopenia insulin resistance (IR) were reversed by SIRT1/mitophagy inhibitors. Our study establishes proof-of-concept to distinct the effect of berberine in sarcopenia IR, and provides strong evidence to support the hypothesis that berberine-induced SIRT1 triggers mitochondrial autophagy pathway and suppresses IR in sarcopenia.
Data preprocessing impact on machine learning algorithm performance
Authors: Amato Alberto , Di Lecce Vincenzo
Published: July 2023

The popularity of artificial intelligence applications is on the rise, and they are producing better outcomes in numerous fields of research. However, the effectiveness of these applications relies heavily on the quantity and quality of data used. While the volume of data available has increased significantly in recent years, this does not always lead to better results, as the information content of the data is also important. This study aims to evaluate a new data preprocessing technique called semi-pivoted QR (SPQR) approximation for machine learning. This technique is designed for approximating sparse matrices and acts as a feature selection algorithm. To the best of our knowledge, it has not been previously applied to data preprocessing in machine learning algorithms. The study aims to evaluate the impact of SPQR on the performance of an unsupervised clustering algorithm and compare its results to those obtained using principal component analysis (PCA) as the preprocessing algorithm. The evaluation is conducted on various publicly available datasets. The findings suggest that the SPQR algorithm can produce outcomes comparable to those achieved using PCA without altering the original dataset.
Comparison of different CFD approaches for the simulation of developing free surface two-phase flow in straight and bent pipes
Authors: Döß Alexander , Höhne Thomas , Schubert Markus , Hampel Uwe
Published: July 2023

Two-phase flows in feed pipes of thermal separation columns have complex flow patterns and are difficult to predict during sizing and design for geometries with non-straight pipes. Numerical simulation codes have only been validated for very few pipe geometries. This work benchmarks the state-of-the-art Volume-of-Fluid model (VoF) and the Algebraic Interfacial Area Density model (AIAD) for the simulation of two-phase flows with the Eulerian/Eulerian CFD approach for straight pipes and horizontal bends as well as for different pipe diameters and flow rates. Both models are compared and shortcomings of the predicted velocity fields from AIAD in the vicinity of horizontal bends are highlighted. While phase dynamics, e.g., for wavy or disperse flows, are not well reproduced by either model, the phase distribution patterns in straight tubes and bends agree reasonably well with experimental data. Regardless of the geometry, better void fraction prediction is obtained for higher flow velocities and the larger pipe diameter. From the numerical results, recommendations for the selection of feed inlet devices are derived.

Published: July 2023

As an extension of recent developments in concrete understanding, an extensive study is currently being conducted on the structural performance of reactive powder concrete (RPC). This article guides how to investigate the shear behavior of RPC T-beams and calculate their ultimate and breaking shear capacities. The mechanical features of this construction material and approach to revising the reactive powder shear hybrid segment T-beams are cast-off in this motion and are investigated in this experimental study. To evaluate the effects of volumetric ratio of steel fibers, silica fume ratio, and tensile steel ratio, introductory section on the effectiveness of T-beam shearing reactive powder, the program of experimentation involved trying four beams. The research aimed to determine the deflection conduct of the load, downtime approach, strain amount over the beams’ depth, and failure form of cracks. In examining reaction powder’s mechanical characteristics mixtures, steel fiber volumetric ratio and silica fume volumetric ratio were also studied. Furthermore, a hybrid beam study revealed that by using reactive powder web and regular concrete in flange effectively, T-beam concert is enhanced when associated with normal concrete T-beams by 12%. Hybrid beams have also revealed that using reactive powder flange and usual concrete in a web effectively advances the show of T-beams when associated with standard concrete T-beams by 28%.
Effect of chloride concentration on the corrosion resistance of pure Zn metal in a 0.0626 M H2SO4 solution
Authors: Loto Roland Tolulope
Published: July 2023

The aftermath of Cl− anion concentration reactions on the corrosion resistance of pure Zn metal in 0.0625 M H2SO4 was examined by potentiodynamic polarization, optical representations, scanning electron image analysis, energy dispersive X-ray (EDX) spectroscopy, open-circuit potential analysis, X-ray diffractometry, weight loss method and X-ray fluorescence. The results show that the degradation of Zn increased with an increase in the chloride concentration from 4.089 and 0.218 mm/year to 10.085 and 4.015 mm/year (polarization and weight loss). The corrosion potential at 0.0625 M H2SO4 to 0.0625 M H2SO4/0.5% NaCl concentration displayed minimal variation (−1.535 to −1.519 V), whereas a significant shift was observed for the plots at 0.0625 M H2SO4/1% NaCl and 0.0625 M H2SO4/2% NaCl (−1.384 and −0.932 V). The weight loss plot at all Cl− anion concentrations displayed an ordered decrease in the corrosion rate analogous to exposure times. The scanning electron microscopic images of Zn in 0.0625 M H2SO4/2% NaCl solution showed significant deterioration and corrosion pits. The image at 0.0625 M H2SO4 solution revealed limited localized and general surface deterioration, while the corresponding EDX data depict the presence of S. The Zn open-circuit potential plot from a 0.0625 M H2SO4 solution was relatively electropositive compared to the plot from a 0.0625 M H2SO4/2% NaCl solution. Both plots exhibited limited reactive-inert transition properties and attained relative thermodynamic equilibrium after 600 s of exposure with final corrosion potentials of −0.91 and −0.97 V at 7,200 s. Zn was the only crystallographic phase identified on its surface before corrosion, whereas ZnS, ZnFes, ZnMnS, ZnMnFeS, and ZnMg4 corrosion products were identified after corrosion.
On the extremum dissipation for steady state incompressible flow past a sphere at low Reynolds number
Authors: Arya Raj Kumar , Thapliyal Devyani , Thakur Amit K. , Kumar Rahul , Verros George D.
Published: July 2023

A methodology based on sound non-equilibrium thermodynamics principles is developed to estimate the extremum dissipation point for steady-state incompressible flow past a sphere at low Reynolds numbers. It is shown, that the extremum dissipation point appears at the point when both the shear stress and the pressure at the surface of the sphere are equal to zero. The Reynolds number and the position of the extremum dissipation flow past a sphere were further estimated with the aid of a mathematical model for pressure distribution on the sphere surface, accounting for both creeping and ideal flow. The parameters of the model were determined by comparison of the calculated pressure distribution at the surface with the available literature data. The conditions at which the separation angle and the extremum dissipation angle coincide were also investigated. It is believed that this work could be used to further elucidate the flow past a sphere.
Kerr effect based optical switching for the assessment of all-optical sequence generator and decoder circuits
Authors: Singh Lokendra , Agrawal Niteshkumar
Published: July 2023

The sequence generator and decoders are used for noise analysis, signal propagation, data processing, and bit error rate analysis. The semiconductor and modern electronic components are facing challenges in terms of processing speed and data rates. However, by using photons rather than electrons as the information carriers, these difficulties can be reduced. Photonic devices attained the operating speed in the regime of terahertz, but sit back due to the diffraction limit, which can be overcome by employing plasmon-based devices or all-optical devices. This work presents a numerical investigation of metal-insulator-metal (MIM) plasmonic waveguides based two-bit sequence generator (SG) and decoder. The structure of SG and decoder circuits are designed within the footprints of 86 × 9 and 140 × 9 µm, by cascading one power splitter (PS) and four Mach-Zehnder interferometers (MZIs), and two PS and five MZI, respectively. To design the MZI, the optimization of the S-bend waveguide, the coupling length of the power splitter, and the length of the interferometric arm are done by recording the output power. The highest extinction ratio of 22.1 dB is attained at the coupling and interferometric arm lengths of 1.5 µm and 5 µm, respectively. The propagation of the optical signal through the structure of SG is observed by using a two-dimensional finite difference time domain method-based tool.
“An Emotional Leap”: Australia’s and New Zealand’s Search for a Post-imperial Belonging
Authors: Jost Sabrina Julia
Published: July 2023

In the 1960s, it became apparent that the seemingly strong ties between Britain and the former settler colonies of Australia and New Zealand were in danger of disintegrating. Britain’s entry into the European Economic Community in the early 1970s was a symbolic end point to their affiliation. Since belonging is closely linked to emotions, this prompted a re-ordering of emotional practices in Australian and New Zealand society. As Britain’s turn to Europe was interpreted by the majority in these countries as an abandonment, Britishness could no longer be the main self-descriptor of identity, and the “British World” no longer the world to live in. Multicultural policies meant a re-evaluation and re-shaping of social coexistence in Australia and New Zealand. Food cultures as cultural heritage were emotionally reinterpreted and appropriated, as they offered new possibilities for identification in the search for a new national identity. The relationship with neighbors in the South Pacific was also placed on a new emotional footing, while the British were excluded via mechanisms of “emotional othering.” These processes of emotional detachment from Britain had direct influences on how Australia and New Zealand positioned themselves in and in relation to the world.
Dietary inflammatory index and neuropsychiatric disorders

Published: July 2023

Neuropsychiatric disorders (NPDs) are considered a potential threat to mental health. Inflammation predominantly plays a role in the pathophysiology of NPDs. Dietary patterns are widely postulated to be involved in the physiological response to inflammation. This review aims to discuss the literature on how dietary inflammatory index (DII) is related to inflammation and, consequently, NPDs. After comprehensive scrutiny in different databases, the articles that investigated the relation of DII score and various NPDs and psychological circumstances were included. The association between dietary patterns and mental disorders comprising depression, anxiety, and stress proved the role of a proinflammatory diet in these conditions’ exacerbation. Aging is another condition closely associated with DII. The impact of proinflammatory and anti-inflammatory diet on sleep quality indicated related disorders like sleep latency and day dysfunctions among the different populations are in relation with the high DII score. The potential effects of genetic backgrounds, dietary patterns, and the gut microbiome on DII are discussed as well. To plan preventive or therapeutic interventions considering the DII, these factors, especially genetic variations, should be considered as there is a growing body of literature indicating the role of personalized medicine in different NPDs. To the best of our knowledge, there is a limited number of RCTs on this subject, so future research should evaluate the causality via RCTs and look for therapeutic interventions with an eye on personalized medicine using information about DII in NPDs.

The Political Accommodation of Islam in Portugal and Ireland: Testing the ‘Convergence Thesis’ in Two Peripheral Cases
Authors: Bernardo Luís
Published: July 2023

Este artículo compara la acomodación política del Islam en Portugal y en la República de Irlanda desde el término de los años 50.  Mucha literatura tiene como foco los sospechos usuales, como Alemania, Francia, Holanda y Gran Bretaña, contextos con comunidades musulmanas de tamaño considerable y establecimiento de considerable duración. Por su turno, no se conoce mucho sobre la institucionalización del Islam en Estados en los cuales la presencia de musulmanes es más reciente y sigue siendo relativamente pequeña. Portugal e Irlanda son dos Estados periféricos, de pequeña dimensión y de matriz católica. Sus populaciones musulmanas representan debajo de 1% de la población total. Los dos casos providencian un teste único a la tesis de Jonathan Laurence sobre la convergencia de los procesos de institucionalización en la Europa Occidental en contextos de diferenciación histórica, política e institucional. Nuestras conclusiones apuntan al hecho que Portugal converge conforme la sugerencia de Laurence, Irlanda no es un caso de convergencia. Lo explicamos recurriendo a dos puntos. Las comunidades musulmanas en Irlanda tienen niveles de diversidad intracomunitaria mayores y eso explica la mayor dificultad de movilización. La posición de la Iglesia Católica Romana es el segundo punto. En Portugal, ese agente institucionalizado tiene un papel de gatekeeper y intermediación mas fuerte que su homólogo irlandés. El proceso de cooptación del Islam es una ilustración. En Irlanda, la Iglesia Católica tiene un papel más ambiguo y no tiene las capacidades ni los recursos para operar como su homóloga portuguesa en el contexto de la institucionalización del Islam en Irlanda.

Evaluation of Colombian coffee waste to produce antioxidant extracts
Authors: Arango-Agudelo Erika , Rendón-Muñóz Yazmín , Cadena-Chamorro Edith , Santa Juan Felipe , Buitrago-Sierra Robison
Published: July 2023

During coffee production, several types of waste such as pulp, mucilage, husk, parchment, coffee silver skin, and spent coffee grounds are generated. The amount of coffee waste and their environmental issues require effective valorization. Those wastes can be used as a source of bioactive compounds. In this work, solid-liquid extraction was used to obtain different solutions, and their phenolic contents, antioxidant capacities, fatty acid profiles, and antimicrobial activities were evaluated. Characterization of the waste materials showed that the highest yield (18.8%) was obtained for spent-coffee grounds. The highest total phenolic contents, caffeine and epicatechin, was observed for coffee pulp extract. Catechin was only observed for parchment. The lipid fraction in the coffee by-products extracts indicated that the spent coffee ground had a higher amount of total lipids, followed by the pulp, and finally the parchment. The most predominant fatty acids in all the extracts were palmitic, stearic, linoleic, oleic, arachidic, and behenic. However, parchment and coffee pulp extracts exhibited an inhibition halo against E. coli bacteria growth.

Comparision between pulping of canola stalks with dimethyl formamide and diethylene glycol was studied in order to investigate the effects of cooking temperature (190˚C, 210˚C, and 230˚C), cooking time (120 min, 150 min, and 180 min) and dimethyl formamide or diethylene glycol (50%, 60%, and 70%) on the properties of pulp and paper. SCAN viscosity was applied to estimate the extent of cellulose degradation. Responses of pulp and handsheet properties to the process were analyzed using statistical software (MINITAB 15). The results showed that DMF pulp of canola was better than DEG pulp of Canola under the same conditions of cooking and organosolv ratio. In DMF pulping and DEG pulping, cooking temperature is a significant factor affecting paper properties. Analysis of results revealed that DMF pulp canola obtained at 230 °C, 180 min, and 70% DMF had a low kappa number (25) , indicating that the desired properties of the final product dictated the optimized pulping conditions.

Rubber wood (Hevea brasiliensis) was esterfied with phenylisothiocya-nate, and dimensional stability, decay resistance, and photo stability of the modified wood was assessed. The chemically modified wood was characterized by FTIR and CP/MAS 13C NMR spectroscopy. Unmodified and modified samples were exposed to a brown rot (Polyporus meliae) and a white rot (Coriolus versicolor) fungus for 12 weeks. Modified wood samples exhibited good dimensional stability and were very resistant to decay. However, phenylisothiocyanate modification of wood was not effective in decreasing photo-yellowing.

With the aim of increasing the sugars concentration in dilute-acid lignocellulosic hydrolyzate to more than 100 g/l for industrial applications, the hydrolyzate from spruce was concentrated about threefold by high-pressure or vacuum evaporations. It was then fermented by repeated fed-batch cultivation using flocculating Saccharomyces cerevisiae with no prior detoxification. The sugars and inhibitors concentrations in the hydrolyzates were compared after the evaporations and also fermenta-tion. The evaporations were carried out either under vacuum (VEH) at 0.5 bar and 80°C or with 1.3 bar pressure (HPEH) at 10 7.5 °C, which resulted in 153.3 and 164.6 g/l total sugars, respectively. No sugar decomposition occurred during either of the evaporations, while more than 96% of furfural and to a lesser extent formic and acetic acids disappeared from the hydrolyzates. However, HMF and levulinic acid remained in the hydrolyzates and were concentrated proportionally. The concentrated hydrolyzates were then fermented in a 4 l bioreactor with 12-22 g/l yeast and 0.14-0.22 h-1 initial dilute rates (ID). More than 84% of the fermentable sugars present in the VEH were fermented by fed-batch cultivation using 12 g/l yeast and initial dilution rate (ID) of 0.22 h-1, and resulted in 0.40±0.01 g/g ethanol from the fermentable sugars in one cycle of fermentation. Fermentation of HPEH was as successful as VEH and resulted in more than 86% of the sugar consumption under the corresponding conditions. By lowering the initial dilution rate to 0.14 h-1, more than 97% of the total fermentable sugars were consumed, and ethanol yield was 0.44±0.01 g/g in one cycle of fermentation. The yeast was able to convert or assimilate HMF, levulinic, acetic, and formic acids by 96, 30, 43, and 74%, respectively.
Influence of adsorbed and dissolved carboxymethyl cellulose on fibre suspension dispersing, dewaterability, and fines retention

The effect of adsorbed and soluble carboxymethyl cellulose (CMC) on dispersing, dewaterability, and fines retention of pulp fibre suspensions was investigated. CMC was added to a suspension in the presence of electrolytes, causing its adsorption to the fibre surfaces, or to a suspension without electrolytes, so that it stayed in the liquid phase. Both the CMC adsorbed on fibre surfaces and that in the liquid phase were able to disperse the fibre suspension due to the ability of CMC to reduce fibre-to-fibre friction in both phases. Adsorbed CMC promoted the formation of a water-rich microfibrillar gel on the fibre surfaces through the spreading out of microfibrils, leading to a decrease in friction at the fibre-fibre contact points and to the increased dispersion of fibres. CMC in the liquid phase of the suspension was in turn thought to prevent fibre-to-fibre contacts due to the large physical size of the CMC molecules. CMC in both phases had detrimental effects on dewatering of the pulp suspension, but adsorbed CMC caused more plugging of the filter cake, and this was attributed to its ability to disperse fibre fines, in particular. Thus, adsorbed CMC also reduced fines retention considerably more than did CMC in the liquid phase of a suspension.
La reactivación económica peruana a través del enfoque de seguridad ciudadana
Authors: Zanabria Cabrera Luis Carlo
Published: July 2023

En el presente trabajo se analizan los problemas estructurales como consecuencia del crítico escenario de pandemia y su relación con la creciente incertidumbre sobre la reactivación económica del país. Para ello, se examinan problemas arquetípicamente clásicos en la realidad peruana, cuya existencia se remonta a épocas anteriores a la pandemia, tales como la informalidad, el desorden urbano y la percepción negativa de la seguridad bajo la perspectiva de los ciudadanos; cada uno de estos conceptos ejerce una marcada influencia dentro de la construcción de las políticas públicas y, al mismo tiempo, hacen referencia directa a inconvenientes socioculturales trascendentales al interior de la sociedad peruana que dificultan el proceso de reactivación. Así, se analizan alternativas a obstáculos tradicionales que frenan el desarrollo y crecimiento económico. En tal sentido, el papel de la seguridad ciudadana y su aplicación a través de las políticas públicas se muestra como una de las formas más sólidas de desplegar las líneas de una política equilibrada enmarcada a la reactivación económica a nivel nacional, puesto que el hecho que la ciudadanía cuente con protección y seguridad en sus actividades urbanas cotidianas es una fórmula consecuente que permite potenciar la interacción económica de las ciudades. Otro punto clave es repensar el ideario gubernamental en la planificación de políticas públicas de seguridad, pues este se halla dominado por la discriminación de clases sociales y la estigmatización de ciertos territorios sin una reflexión sólida que lo sustente.
