Invited Perspective: Current and Potential Use of Highly Fibrillated Cellulose in the Paper and Board Industry
Authors:   FiberLean Technologies Ltd., Par Moor Centre, Cornwall, PL24 2SQ, UK, Phipps Jonathan
Published: May 2024

The use of microfibrillated cellulose (MFC) in the paper industry has become established following many years of development by both academic and industrial researchers. Commercial installations typically use mechanical disintegration techniques such as refiners and grinders to convert aqueous suspensions of pulp fibres into a material consisting of fibrils and fibre fragments with diameters ranging from the nanometre to the micron scale. MFC suspensions of a few percent solids content show very high viscosity at low shear rates, but also very significant shear thinning behaviour, rapid viscosity recovery after shear and high filtration resistance. MFC added to paper furnishes at up to 5% by weight functions as a strength additive, enabling increases in mineral filler content, improvements in paper properties, reductions in weight and cost savings across a wide range of paper and board grades. As a complementary technology to pulp refining, addition of MFC offers process flexibility as well as improved wet web strength and runnability, reduced air permeability and increased z-direction strength. Although the fine fibrils of MFC do not dewater easily on their own, when added at low levels to paper their effect on machine drainage can be managed without loss of paper machine speed. In recent years, MFC has attracted much interest as a coating material. Layers or films of pure MFC show near-zero air permeability, high resistance to oil and grease and an effective barrier to organic vapours and oxygen. Mixtures of mineral particles and as little as 15% MFC provide an effective surface for water-intensive printing techniques such as flexography and inkjet. Application of MFC suspensions after the wet line of a papermachine has been demonstrated as a practical solution to obtain coatings, exploiting the rheological behaviour of the MFC to achieve excellent holdout onto a poorly-consolidated sheet, and using the vacuum and press sections of the machine to remove excess water. Further development and commercialisation of this technology, together with low cost MFC production and improved product characterisation, should ensure the continued growth of its use in the paper and board industry.

Mineral fillers are indispensable in many industrial branches and are used in a variety of different materials. In plastic technology they act as a classic extender to lower the costs of the production process but also as “active fillers” to improve the mechanical and optical property profile. In the paper industry, fillers are also used to reduce raw material costs and to adjust the optical as well as surface properties. However, fillers entail the problem that their application quantity is sharply limited. Inorganic fillers show no binding properties. They reduce the product strength with higher use and lead to complications in the further processing of the products (e.g. increased dust propensity during the packaging and printing processes). In order to expand the use of fillers and their positive effects on varying products and to prevent the negative effects of the material in parallel, mineralized cellulosic structures should be created for versatile applications in different branches of industry.

Foam forming of cellulose fibre materials is based on an interaction between fibres and bubbles, which can take several material properties to new levels. To control the formed structure, the mechanisms of this interaction have been systematically investigated. This started with captive bubble studies where we analysed the interaction of a single bubble with various smooth cellulose and silica model surfaces. The bubbles adhered only to hydrophobic surfaces, and this attraction was sensitive to the surface tension. From this simplest case, the studied system gradually became more complex. We found that a bubble adheres weakly also to a submerged cellulose nanofibre (CNF) film, which could be explained by nanoscale surface roughness capturing nanobubbles. The interaction with real fibres was studied by pressing a single bubble against a fibre bed in water and sodium dodecyl sulphate (SDS) solution. Fibre type and surface tension had all apparent effects on the attachment. In the case of natural fibres, the presence of hydrophobic lignin clearly increased the fibre attachment on a bubble, while added SDS decreased the attachment with all fibre types. These findings agreed with the mechanisms found earlier using the model surfaces. Finally, when forming thick nonwoven materials using hydrophilic and hydrophobic viscose fibres, differences in fibre network structure and strength properties depended on the fibre hydrophobicity and surfactant type, as suggested by the results obtained in simpler systems.

Could stem cell study in space avail patients and researchers on Earth?
Authors: Montaser Laila Mahmoud
Published: May 2024

With a growing proportion of people that are 65 years and older, age-linked cases like stroke, cancer, mentality, and degenerative illness lead to an escalating health load in the world. Regenerative medicine researchers are frequently acting to progress stem cell-based remedies that could assist cure patients with these situations. However, stem cell-based treatments require great numbers of stem cells that are hard to produce. The outgrowth media utilized in modality cell cultures do not supply perfect growth conditions, and even if stem cell amplification is effective, it is usually a slow operation. This triggers it defying tolerating stem cells into the big numbers required for clinical implementations. Cell cultures in a laboratory on Earth cultivate in a single layer –a 2D design– as gravity causes precipitation and the culture medium pushes downward on the cells. As an outcome, scientists want a template or scaffold to boost the up growing tissue in 3D tissue engineering and regenerative medicine are strategic zones of concentrate for the International Space Station (ISS) Lab. In a weightless milieu as space, cells could display selectively unstrapped expansion and gather into congregation 3-D builds. This could open the prospect of “macro-tissues” –organs – may to be created from these 3-D cell structures. Beside, in the trust of concluding several of the mysteries of how stem cells expand, split and compose into tissues. Aspire to stem cell research to be the zone that could be progressed in microgravity. Hope for the ISS National Lab to fit as an entirely realistic feasible practical robust down-to-earth space laboratory for workable and potentially safe to grow mesenchymal stem cells (MSCs) for potential future clinical applications on Earth.
Health and ecological risk assessment of heavy metals in water and sediments within a data scarce urban catchment in Tanzania – A case of Ngerengere River, Morogoro Municipality

Published: May 2024

Low-, middle- and high-income countries, exhibit indications of risks associated with water quality. The study investigated heavy metal concentrations in surface water and sediments within the Ngerengere River and its tributaries (Kikundi, Bigwa, and Morogoro) drain within in the Morogoro Municipality of Tanzania, an Urban Catchment Area (UCA) with limited available data mainly because of inadequate monitoring and reporting capabilities. Analysis of health and ecological risks associated with heavy metal pollution was also carried out using health risk assessments models, pollution indices, and multivariate analysis techniques. Between the dry and wet seasons of 2023, water and sediment samples from (13) sampling stations strategically established along the Ngerengere river and its tributaries were analyzed for six heavy metals (Pb, Cr, Ni, Cd, Cu and Zn) using the Atomic Absorption Spectrophotometer Model Perking Elmer 850 Graphite Furnace and Perking Elmer AS 800 Auto-sampler coupled with a computer interface for operational, displaying and reading the results. The calculated degree of water contamination (Cd) values in river water in both dry and wet seasons ranged from 0 to 6.803 indicating low and high degrees of contamination respectively. Heavy metal concentration in sediment decreases in the order of Zn>Ni>Cr>Cu>Cd>Pb. The non-cancer risk index (HI) via ingestion and dermal pathways in dry and wet seasons for both children and adult groups was <1 hence no non-cancer risk, However, cumulative dermal and ingestion exposure in both children and adults indicated potential cancer risk in dry and wet season. The analysis of ecological risks associated with heavy metal enrichment in the sediment indicated high enrichment of sediments with Cd, Ni and Zn. Conclusively, in wet months, risk indices tend to be low, while in dry months, they typically remain high.
Study of the structural behavior of High-Performance Concrete bridge decks
Authors: Nehar Kheira Camellia , Benamara Dalila
Published: May 2024

The manufacture of High-Performance Concrete (HPC) in bridge deck construction is part of an experimental framework that is also developing in the numerical domain to fill the existing gaps in understanding its behavior. However, the numerical modeling of HPC for bridge decks remains largely under-explored. It is precisely this gap that has sparked our interest in this research area, thus giving our work its innovative character.

This study primarily aims to deepen the understanding of the behavior of HPC bridge decks while manufacturing an efficient and economical HPC using local materials possessing very high properties (mechanical, physical, elastic, durability, and implementation) and advanced numerical modeling. This modeling has enabled us to study the behavior of HPC bridge decks in relation to cracking through the Extended Finite Element Method (X-FEM), an innovative solution that enables the modeling of discontinuities without complicating the process. This has been confirmed by the quality of the results, which show an excellent correlation with experimental data, underscoring the accuracy of the modeling. These results also reveal that the use of HPC in bridge construction can significantly reduce degradation risks while enhancing their performance. Consequently, the adoption of HPC stands out as a beneficial strategy, not only to minimize bridge degradation but also to extend their durability.

Place and application of the new Law "On Administrative Procedure" in the regulation of public e-services
Authors: Khliborob Natalia
Published: May 2024

The article is dedicated to the analysis of the place and application of the new Law "On Administrative Procedure" in regulating public electronic services in Ukraine. Enacted on December 15, 2023, the Law aims to establish a system of unified, understandable, and transparent interaction between public authorities and citizens and businesses. The article examines the main provisions of the Law, focusing on the principles of administrative procedure and norms regulating the resolution of administrative matters using electronic digital technologies. Based on the analysis of legislation texts, comparative analysis, and consideration of practical aspects of the new law's implementation, the conclusion is drawn regarding the importance of applying its norms to the sphere of public services, including those provided through digital technologies. It is found that the Law of Ukraine "On Administrative Procedure" sets general standards for administrative procedure ensuring the observance of rights of individuals and legal entities in relations with administrative authorities, regardless of whether such interaction occurs through physical or electronic channels. Special legislation may define the specifics of providing certain types of public services, but the general standards of the Law of Ukraine "On Administrative Procedure" must be adhered to. The article also highlights the main directions for further research and possible directions for further development of legislation in this area. The application of the provisions of the Law of Ukraine "On Administrative Procedure" allows not just to copy the logic of the paper world into digital services, but to develop innovative approaches. This means that the right to participate in the administrative process can be implemented through online offices, the possibility to submit documents in electronic format, support for communication through digital channels and the creation of additional functions that complement the main service
Strategic Coherence and Company Performance: Research Results
Authors: Mielcarek Paweł
Published: May 2024

Objective: Maintaining cohesion of different elements of the organisation is crucial, especially for building effectiveness, implementing a business model and improving performance. The key aim of this article is to analyse the relationship between strategic coherence and a company’s performance.
Research Design & Methods: Strategic coherence is the author’s concept allowing measurement of vertical and horizontal adjustment of a business entity. Vertical adjustment describes the fit of the elements of the business model to the company strategy. This is captured by following measurements: 1) how a company’s goals are cascaded, 2) what is the feedback in terms of the cohesion of the components of the business model with its strategy and 3) how the control process of strategy implementation and financial outcome are organised. Horizontal adjustment covers the phenomenon of a business model’s cohesion. It measures: 1) how customer value is created, 2) how value is attained by a business and 3) how a synergy effect is created within an organisation. In total, 400 medium and large sized companies were researched.
Findings: Based on the survey results companies have similar levels of strategic coherence in both horizontal (6.29) and vertical (6.47) dimensions (in a 1.00–10.00 scale). In general it is confirmed that the higher the strategic coherence level is, the higher the profit, the competitive advantage, and other analysed figures.
Implications / Recommendations: Achieving a higher level of coherence should improve integration between strategic goals, actions taken to implement them, and cohesion of business model components. A critical issue is creating the ability to identify the essential elements of strategy, and on their basis reconcile competing or conflicting ideas and paths of development more coherently than other organisations. However, pushing towards total coherency can cause some imbalance between the long-term and short-term results of the firm.
Contribution: This article provides a unique insight into how strategic coherence is shaped in a two dimensional perspective – vertical and horizontal adjustment. In addition, it introduces guidelines for improving the strategic coherence of companies in terms of improving performance.
Wielowymiarowa analiza dyskryminacyjna jako instrument oceny zagrożenia upadłością przedsiębiorstw należących do indeksu WIG-spożywczy
Authors: Firlej Chrystian , Firlej Krzysztof Adam
Published: May 2024

Objective: To assess the financial situation of selected enterprises included in the WIG-food index in 2019–2021 from the point of view of the risk of bankruptcy.
Research Design & Methods: Four models of multidimensional discriminatory analysis were used to assess potential bankruptcy risk (Dorota Hadasik’s Model, Model Z6 INE PAN, Model Z7 INE PAN and the so-called Poznań Model). The entities selected for the study were all Polish companies traded on the WIG-food index in all quarters of the years 2019–2021. This condition had to be met due to the volatility of the composition of the WIG-food index on a quarterly basis (quarterly revision of the index portfolio). Two research hypotheses were formulated in the article. First, selected discriminant analysis models are an effective tool for assessing companies included in the WIG-food index for the risk of bankruptcy. And second, multidimensional discriminant analysis is a valuable and complementary tool to other methods of assessing the risk of company bankruptcy.
Findings: Companies included in the WIG-food index in 2019–2021 were in a very good financial situation with the exception of two companies, which faced the threat of bankruptcy in 2019: ZPC Otmuchów SA and Pamapol SA. Three of the models used indicated that the companies were moving in the wrong direction: Z6 INE PAN and Z7 INE PAN (ZPC Otmuchów SA) and the Poznań Model (Pamapol SA). This may suggest that these models were highly sensitive. Hadasik’s Model did not show any company to be at risk of bankruptcy in the analysed period.
Implications / Recommendations: One implication of the research is that the number of variables in discriminant analysis models does not work to exaggerate their efficiency. Two of the models used (Z6 INE PAN and Z7 INE PAN) returned similar results. This is mainly due to their being constructed similarly. Furthermore, none of the selected models showed high sensitivity to detecting the threat of bankruptcy among the companies analysed, though they could be used to faster warn about potential and actual problems.
Contribution: The research contributes to the development of knowledge on the use of discriminatory analysis models to assess bankruptcy risk of food industry enterprises in Poland.
Sposób poboru pozaodsetkowych kosztów kredytu a poziom wskaźnika RRSO
Authors: Redo Magdalena
Published: May 2024

Objective: To assess how the method of collecting non-interest loan costs (NILC) impacts the Annual Percentage Rate of Charge (APRC), and to analyse how the specific structure of its formula impacts the APRC level depending on the method used to collect the NILC.
Research Design & Methods: Inductive reasoning and discussion of the effects of using selected combinations of NILC collection method for the APRC value in the case of loans repaid in installments. A case study is presented.
Findings: Postponing NILC payment reduces the APRC, as a result of which a loan with a higher NILC amount (but spread over time) may have a lower APRC than one with lower costs, but be payable at the time of loan disbursement. The method of settling the commission is important for the APRC level – whether it reduces the amount of the loan disbursed (yielding a higher APRC, because the costs are related to a lower amount of debt) or increases the debt. So it may turn out that while two offers seem the same, one may differ in how it settles NILC, despite the lower APRC, and prove more expensive (it will have a higher NILC amount, in other words). Similarly, loans with identical costs in PLN may have different APRC levels. A small change in the commission level may cause strong and varied changes in the APRC level – more or less than proportional to the change in the commission amount (depending on the length of the loan period), and be stronger or weaker (depending on the scale of NILC change).
Implications / Recommendations: The APRC does not allow debtors to make loan decisions correctly. This measure can only be used to compare the cost of loans granted on identical terms, i.e. for the same period of time, with the same frequency and with the same method of repayment of principal and interest installments and with the same method of collecting and settling NILC. In any other case, decisions made on the basis of the APRC may be wrong.
Contribution: The issue of APRC remains unexplored both in Poland and the EU, suggesting the research is innovative.

Special Economic Regime as a Means of Conflict Resolution in the Temporarily Occupied Territories of Ukraine
Authors:   Volodymyr Dahl East Ukrainian National University, Ukraine, Sieriebriak Stanislav
Published: May 2024

Over the past nine years, the Ukrainian economy has been developing in the context of partial occupation of its territories, violation of human and civil rights and freedoms, and seizure of state property. On February 24, 2022, a neighboring state invaded Ukraine, which led to the introduction of the legal regime of martial law in Ukraine. In the article, the author identifies the main approaches to regulating the economic situation in the temporarily occupied territories and determines what the State’s policy should be after their de-occupation. The author also examines the content and features of the concepts of occupation and de-occupation. The concept of Ukraine’s state policy on the temporarily occupied territories requires a detailed analysis, primarily of its legal framework, institutional mechanism, identification of problems and outlining of ways to solve them. This requires scientifically balanced and well-founded approaches, timely, coordinated and predictable actions by the public authorities of Ukraine, and consideration of positive international and national experience. The impact of the martial law regime on almost all spheres of public life, all areas of state policy, the legal framework and institutional structures for the implementation of state policy, and the forms and methods of work of state and local government bodies is obvious. There is a natural need to improve a significant number of existing legal acts of Ukraine and adopt new ones in this area. It is important to expand the range of entities responsible for ensuring the de-occupation of the temporarily occupied territory of Ukraine. The author emphasizes the need to define a system of legal means which can form the basis of a special economic regime both in the temporarily occupied territories and in the de-occupied territories. It is also important to eliminate the imbalances in the development of different regions of Ukraine, as well as to determine the priorities for restoring the economic system in the de-occupied territories.

The article deals with the concept of fiduciary activity of an attorney-at-law. The author analyzes foreign experience, in particular, the EU and the USA on fiduciary activity, and conducts a comparative legal analysis. The author examines the prospects for introducing such activities into national legislation on the advocacy. The author focuses on European legislation, in particular, the Common Code of Practice for Lawyers of the European Community. The author examines in detail the procedure for fiduciary activities in the EU and the USA, with special attention paid to the procedure for providing such activities by attorneys. The author emphasizes the advantages and disadvantages of fiduciary activities in foreign countries. The author examines the draft amendments to the national legislation on the Advocacy regarding the introduction of fiduciary activities. The author emphasizes that although the experience of foreign countries with regard to fiduciary activities is quite positive, one should not try to quickly and blindly implement European standards into national legislation, as this will take time. The author determines that a lawyer who manages client’s funds in the course of performing professional duties in the territory of one of the Community States must comply with the rules for managing client’s funds and maintaining financial records established by the competent authorities of the State of registration. The author of the article also establishes that the competent authorities of all Community countries have the right to control and confidentially examine the financial documents of an attorney-at-law on the client’s funds placed at his disposal in order to identify cases of violation of the rules to be observed by the attorney- at-law and to impose sanctions on him in case of the above violations. The advocate, who manages the client’s funds in the course of the performance of his or her professional duties in the territory of one of the Community states, shall comply with the rules for the management of client’s funds and the maintenance of financial records established by the competent authorities of the state of registration.

The paper describes in detail the procedure for the preparation of a granular bulk NiMoW catalyst and a supported reference NiMo/Al2O3 catalyst. Mention is made of investigations of the supported and bulk catalysts by various physico-chemical methods (nitrogen adsorption-desorption method, X-ray photoelectron spectroscopy, TPD-NH3, HRTEM and X-ray diffraction analysis). The experiments to estimate catalytic activity and compare rate constant of hydrodesulfurization of dibenzothiophene using both catalysts have been carried out. It is shown that textural properties of the catalysts significantly differ. The supported catalyst has more developed specific surface area and pore volume than the bulk catalyst. TPD-NH3 showed an increased acidity of the supported catalyst in comparison the bulk catalyst. It is shown by the X-ray photoelectron spectroscopy method that in both samples Mo on the surface is present exclusively in the form of Mo4+ ion. However, the bulk catalyst differs from the supported catalyst in that it contains a larger amount of Ni as part of the active NiMo(W)S phase. The catalytic activity tests demonstrated that the bulk catalyst is more active at 240, 250 and 260°C, it is discovered that the rate constant in hydrodesulfurization of dibenzothiophene for the bulk NiMoW catalyst is twice higher at 240ºC than that of the supported NiMo/Al2O3 catalyst.
Features of electronic states in the vicinity of band gap and atomic structure of Ta- and Nb-doped Li7La3Zr2O12
Authors: Vlasov Maxim I. , Surzhikov Evgenii A. , Germov Alexander Yu. , Il'ina Evgeniya A. , Weinstein Ilya A.
Published: May 2024

Li7La3Zr2O12 is one the most promising materials for Li-conducting solid electrolytes. The incorporation of Ta5+ and Nb5+ into the Zr4+ sites stabilizes its cubic structure and significantly enhances Li-conductivity, due to the formation of Li vacancies. In this research, we have studied the band gap features of Ta and Nd-doped Li7La3Zr2O12. Our findings indicate that Nb ions are present not only in the +5 valence state, but also in the +4 state, leading to the formation of oxygen vacancies. In the case of the Ta-doping, such an effect was not observed. This could be the reason for the approximately one order of magnitude higher lithium conductivity observed in the case of the Ta doping, in comparison to the Nb doping.

Published: May 2024

In this work, the photoelectrochemical properties of g-C3N4 modified with Pt, Ir and Ir/Pt bimetallic co-catalysts were studied. All prepared photoelectrodes were tested in a two-electrode cell by cyclic voltammetry, impedance spectroscopy, and the Mott-Schottky method. First, the optimal electrolyte (triethanolamine, NaCl, NaOH, Na2SO4) was selected. The highest photocurrents were recorded in 0.5 M Na2SO4. This electrolyte was used for the subsequent tests. Second, the photoelectrodes loaded with the noble metals are studied. It was shown that in case of monometallic co-catalysts, the deposition of noble metal is accompanied by the decrease of the short-circuit current density and the growth of open-circuit voltage. The simultaneous presence of bimetallic co-catalysts can significantly affect the semiconductor electron structure and photogalvanic properties. Some correlations between the short-circuit current density and the oxidation state of the noble metals were found. A linear correlation between Pt0/Pt0+Pt2+ and Jsc was observed. It was also shown that the presence of iridium in Ir3+ form favors the photocurrent generation. The highest values of the photocurrent were obtained for g-C3N4 and were equal to 0.57 mA/cm2.

The key to this study is to explore the relation between renewable energy and trade openness under climate change impacts on international trade. This study is based on the analyses of trade openness index and the Notre Dame-Global Adaptation Index in measures of research of the transfer of renewable energy technologies globally, promotion of the growth of renewable energy share, and the country's current vulnerability to climate disruptions. Research is focused on evaluation of low-carbon trade, analysis of renewable heat, and estimation of the impact of renewable energy on trade openness under climate disruptions. Research verified that development of renewable energy can reduce the human impact on climate change, but such technologies are not available to all countries; because of this, different countries may be affected by climate change to varying degrees. The implementation of renewable energy technologies should help countries become more resilient to climate change through the availability of appropriate means of producing renewable energy; however, this is possible subject to the country's openness to the arrival of goods and technologies from outside-increasing trade openness level. Countries with open and competitive markets are more inclusive to adopt and support the renewable energy technologies and their development. From another position, development of trade and deep integration of economy can create external dependence on imported energy sources and block the development of domestic renewable energy sectors. The economic challenges in the field of renewable energy need the focus of governments and policy makers on supporting the stability of renewable generation facilities, increasing the reliability of energy supply, protection from seasonal changes in demand for electricity, support of the energy cooperatives and private consumers of renewable energy, and transition the public transport sector for renewable energy sources. Further research in this direction has prospects, because globalization is a stable trend of recent decades, and allows for an even distribution of efforts to produce various products and provide them to the population, but decarbonization potential of renewable energy production is untapped as fossil fuels dominate in largest world markets.

Published: May 2024

Most central banks tightened monetary policy considerably over the past few years as inflation surged globally. Though effects of the COVID pandemic on global supply chains and labor markets was a common factor driving inflation higher across economies, domestic factors led to notable variation in the timing and extent of monetary policy responses.
La importancia del capital social en proyectos participativos de restauración ecológica
Authors: Ceccon Eliane
Published: May 2024

El capital social es un constructo teórico que propone escenarios donde valores como la cooperación, la comunicación y la confianza entre las personas pueden crear un ambiente ideal para la solución de problemas socioambientales. Por su parte, la restauración ecológica está ganando impulso, ya que 2021-2030 será “La Década de la Restauración de los Ecosistemas”. Sin embargo, varios autores consideran que la restauración ecológica, además de reparar un ecosistema, debe tener como objetivo generar acciones colectivas, aprendizajes sociales, nuevos valores humanos y nuevas relaciones políticas con la naturaleza. El objetivo de este estudio es evaluar la importancia del capital social en la permanencia de dos proyectos de restauración participativa, en dos comunidades indígenas tradicionales marginadas de México, a través de la metodología de estudio de caso y de observación participante. Se encuentran evidencias de que las diferencias en los niveles de capital social entre las dos comunidades afectaron la permanencia de los dos proyectos.
Patrimoni cultural i memòria

En aquest novè Quadern de la Càtedra Josep Anton Baixeras de Patrimoni Literari ens hem deixat seduir per la coincidència d’una sèrie d’aniversaris d’il·lustres escriptors, artistes i activistes catalans. Sense acollir-nos a la fórmula de manera habitual, els cent anys del naixement d'escriptors de la dimensió de Joan Fuster, Gabriel Ferrater i Guillem Viladot i de la mort de Miquel Costa i Llobera ja haurien justificat l'excepció; però els cent cinquanta del naixement de Francesca Bonnemaison, model del feminisme conservador d'un segle enrere, i els cent del gran fotògraf Francesc Català-Roca ens han permès completar el Quadern amb un repertori de luxe.

La seguridad y la privacidad han preocupado a la Humanidad desde tiempos inmemoriales. A lo largo de la historia, se han diseñado y aplicado distintas estrategias, herramientas y técnicas para hacer frente a espías y enemigos. En los albores de la computación y la Ingeniería Informática, el profesor Lance Hoffman ya destacó la importancia de velar por la seguridad en todo lo referente a la computación para garantizar el éxito de ésta. Así pues, una gran comunidad de científicos e ingenieros hemos ido trabajando para dotar de seguridad a las tecnologías que sustentan la Sociedad de la Información. Por otra parte, la aparición de la Internet Social hace necesario que los expertos en seguridad y criptografía desarrollemos sistemas que protejan a los usuarios de las Tecnologías de la Información y las Comunicaciones de un malintencionado Gran Hermano. La Reunión Española sobre Criptología y Seguridad de la Información (RECSI) es el congreso científico español de referencia en el ámbito de la Seguridad en las Tecnologías de la Información. En septiembre de 2010 se celebrará la undécima edición de este congreso en Tarragona. Las pasadas ediciones tuvieron lugar en Palma de Mallorca (1991), Madrid (1992), Barcelona (1994), Valladolid (1996), Torremolinos (1998), Santa Cruz de Tenerife (2000), Oviedo (2002), Leganés (2004), Barcelona (2006) y Salamanca (2008).
El món de les patents a Tarragona
Authors: autores Varios
Published: May 2024

El món de les patents fa un balanç de les empreses de les comarques de l'Ebre i del Camp de Tarragona que protegeixen els seus invents. És la primera vegada que es es du a terme un estudi sobre patents a les empreses i, si més no, els resultats obtinguts són molt interessants. Els autors del treball han rastrejat les bases de patents espanyoles i internacionals a la cerca de les patents en mans d'empreses locals, i han complementat aquesta tasca amb un treball de camp a partir de visites directes a les empreses. El panorama de les patents a casa nostra ens indica que les empreses locals protegeixen amb freqüència el seu patrimoni tecnològic i també ens mostra que es tracta d'un col·lectiu dempreses que, sovint, passen desapercebudes. Van fent la seva feina, van obrint mercats a lexterior i van creixent sense fer gaire soroll. Sovint sense gaudir del protagonisme que es mereixen.

Tecnologías digitales en la educación inclusiva: oportunidades, desafíos y perspectivas para personas con discapacidad cognitiva
Authors: Screpnik Claudia R.
Published: May 2024

Este trabajo destaca el uso de tecnologías digitales (TD) en la educación para mejorar la inclusión de personas con discapacidad cognitiva. El 15% de la población mundial enfrenta discapacidades, y resulta en desafíos socioeconómicos. Esta reflexión utiliza como base la revisión sistemática de la literatura realizada en el marco de una tesis doctoral en Tecnología Educativa. Los argumentos a favor de las TD se centran en su adaptabilidad, accesibilidad y oportunidades de interacción, lo que permite un aprendizaje más personalizado y enriquecedor. Sus beneficios incluyen romper barreras geográficas y socioeconómicas, facilitar la comunicación y colaboración entre estudiantes y fomentar la autonomía y empoderamiento. No obstante, se deben considerar desafíos éticos como la privacidad de datos y la brecha digital. Escuchar las perspectivas de educadores y familias es vital para una implementación efectiva. En conclusión, el uso adecuado de las TD puede promover una educación más inclusiva y enriquecedora para personas con discapacidad cognitiva.
