SUSTAINABILITY INNOVATION TO CHANGE TEXTILE INDUSTRY
V. CAMBRA

VICENTE CAMBRA's personal collection (2024). 1

Abstract
Sin lugar a duda el sector textil y confección está siendo uno de los sectores con un mayor número de actuaciones en materia de sostenibilidad y economía circular, principalmente en el ámbito regulatorio como normativo, con un alcance principalmente europeo, que impacta de lleno en el modelo productivo y de negocio de estas empresas. Todo ello viene provocado por la fuerte presión social, política y legislativita en materia medioambiental a la que está expuesto el sector textil en Europa y en consecuencia también en España. Por un lado, en materia de residuos, la Directivas 2008/98 sobre residuos, la Directiva 2018/850 sobre vertido de residuos y la actual Propuesta de Modificación de la Directiva 2008/98 en curso con su anexo correspondiente. Así como, en este caso, la Ley 7/2022 sobre residuos (y suelos contaminados) para una economía circular. Por otro lado, para los consumidores se encuentra la Directiva 2005/29 sobre prácticas comerciales, la Directiva 2011/83 sobre derechos de los consumidores y la Directiva 2024/825 y su anexo sobre su empoderamiento para una transición ecológica, así como la actual Propuesta de Directiva relativa a la justificación y comunicación de alegaciones medioambientales explícitas. Y el Reglamento 1007/2011 sobre denominaciones de fibras textiles, etiquetado y marcado en curso de revisión. También, en materia de ecodiseño, se encuentra la Propuesta de Reglamento Europeo con sus anexos correspondientes más sendos documentos soporte sobre su Primer Plan de trabajo incluyendo la categoría textil y Pasaporte Digital para textiles. Y por último, la diligencia debida la Directiva 2022/2464 para la presentación de información sobre sostenibilidad y su posterior Reglamento Delegado 2023/2772. Todo ello, está derivando en un cambio del modelo productivo de las empresas de la industria textil y confección, de un modelo lineal y un modelo cada vez más circular. En este sentido y ante el contexto actual, la innovación está siendo la palanca clave y estratégica en esta transformación del sector. En este artículo vamos a centrarnos en las líneas maestras del sector en I+D+i que están permitiendo el cambio de este modelo cada vez más circular. En primer lugar se encuentran las diferentes técnicas de reciclado, ya sea de tipo mecánico, para el desgarrado y procesado de fibras, termoquímico, aplicable para la obtención de aceites de pirólisis y biocombustibles, y reciclaje químico, en el que los residuos post-consumo se descomponen en sus componentes químicos básicos para crear de nuevo polímeros con las mismas propiedades técnicas que los vírgenes. Por otro lado, el ecodiseño está llamado a cobrar especial protagonismo, ya que engloba todo el análisis del ciclo de vida desde el propio diseño hasta el final de su vida útil, desde una perspectiva de minimizar y reducir su impacto medioambiental. Además, también existe una línea de actuación de alargar el ciclo de vida de los productos textiles, mayor durabilidad, así como el empleo de materias primas procedente del reciclado y que los productos desarrollados sean reutilizables o reciclables. Los biomateriales son también un campo de investigación consolidado en el que se buscan alternativas a los materiales de origen no renovable como las fibras sintéticas. En este sentido hay dos estrategias muy diferenciadas, por un lado, el origen que sea de fuente renovable, y por otro lado, su eliminación, favoreciendo que sean más biodegradables o compostables. Por otro lado, en cuando a los procesos, se busca también la reducción del uso de productos químicos, así como la búsqueda de alternativas de fuentes naturales, como lo son los colorantes naturales, los cuales son pigmentos orgánicos que se extraen de recursos naturales como plantas, hierbas, madera, frutas o minerales. Los procesos de producción de toda la cadena de valor en general y los procesos de acabado en particular están siendo objeto de investigación e innovación desde diversas estrategias, con el fin de incrementar la eficiencia energética, tanto por razones medioambientales, como por el incremento de los costes energéticos. Los procesos de ennoblecimiento y acabado textil son especialmente intensivos en términos energéticos. Las líneas más destacadas en este sentido se orientan al desarrollo de alternativas a los procesos actuales (calentamiento por microondas o por inducción electromagnética) combinado la integración de estos nuevos sistemas desarrollados con la utilización de energías renovables. Y por último, la gestión integral del agua es una línea estratégica clave especialmente para las empresas del llamado ramo del agua (acabado y ennoblecimiento textil). En este contexto se enmarca toda línea de investigación destinada a minimizar el uso de agua y maximizar su reutilización y reciclaje. Destacan las tecnologías de tintura y acabado por micronebulizado, que son procesos que requieren de una menor cantidad de agua (con reducciones de hasta el 80% del consumo del agua en el proceso de tintura) así como también se reduce el uso de productos químicos. En este contexto también es de señalar las líneas de investigación para el tratamiento y la reducción de los microplásticos y su impacto en los efluentes textiles.

Own brands and manufacturer brands in the food sector within the Catalan context
J. Valls

Josep Francesc Valls's personal collection (2024). 1

Abstract
The strong growth in the share of own brands in Catalan supermarket shelves and the decline in manufacturers' brands requires a historical review of the reasons that have led to this situation following the respective business models; and at the same time, to a comparative analysis of the values that consumers give to each other. To develop the study, a survey is carried out on a representative sample of Catalans to find out the perception of the values they assign to their own brands and those of manufacturers. The following aspects are taken into account: quality, innovation, variety, safety, trust and guarantee, healthy and healthy components, care for the environment, association with humanitarian causes, identification on the shelf, stable price, cheap, adaptation to customer tastes, stay ahead of demands, creativity by providing services, product advertising; all these values shape the brand environment. Along with the field work, they carry out group dynamics with manufacturers and distributors to grasp the vision they have of the business from a strategic and future perspective. The communication that will be presented will show: 1) the historical evolution of the relationship between own brands and manufacturer brands; 2) the state of the current competition and compared business model; 3) the perception of Catalan consumers of the values of certain brands, based on the change in habits experienced; 4) collaboration experiences and cases between own brands and manufacturers' brands; and 5) the conclusions about the future scenario.

Les tensions als mercats de l'energia i les primeres matèries
R. Murillo

Ricard Murillo's personal collection (2024). 1

Abstract
Aquest article consta d’un resum de la situació geopolítica viscuda després de la pandèmia de la COVID-19 i com aquesta ha impactat al preu de les matèries primes globals, principalment el petroli el gas natural. S’expliquen les causes de la seva variació durant aquest període (entre d’altres, disrupcions en l’oferta, temors sobre una menor demanda o augment del risc geopolític). Més enllà de l’impacte que aquestes fluctuacions han tingut sobre l’economia i la política internacional, valorem quin ha estat l’impacte sobre l’economia catalana, a través de les dades de producció industrial per sectors. Així, podem veure quins han estat els sector més afectats de la crisi energètica, presumiblement aquells més intensius en l’ús de l’energia. També es fa una comparativa amb el conjunt de l’estat espanyol i de la zona euro per veure si hi ha hagut comportaments idiosincràtics a Catalunya.

Impacto económico de la sequía en Catalunya. Impacto sobre los resultados empresariales
J. Santacruz Cano, J. Zuleta

3r Congrés d'Economia i Empresa de Catalunya - Abstracts.

Abstract
Este documento analiza el impacto de la coyuntura de desabastecimiento de agua desde mayo de 2023 en Catalunya. Como factor determinante para la economía, no solo del sector primario, sino que de cada uno de los sectores que la integran. La actual conyuntura de debastecimiento hidrico que atraviesa Catalunya ya se contabiliza en cientos de millones de euros, inicialmente ha afectado al sector agroalimentario, pero con el paso del tiempo se ha extendido al resto de los sectores del tejido empresarial catalán. Al punto de que actualmente es la principal factor de decrecimiento de las proyecciones del PIB de la comunidad, su no resolución supone un grave problema cuando se acerca el verano, y el debastecimiento de agua puede generar grandes perdidas en el sector de la hostelería en su momento de mayor ocupación del año, sector vital no solo para Catalunya, sino que también para España. Sumado a las afectaciones energéticas producto del estado de los embalses a un 15% de su capacidad, las cuales repercuten en todos los sectorees económicos de la comunidad, al igual, que en las economías domésticas. En el siguiente paper se realizará un estudio sobre el impacto del debastecimiento de agua calculándo el índice de productividad, coste ponderado de capital, y existencias producidas de una muestra representativa de 20 compañías de los sectores más damnificados, salvo por la hostelería . A partir de la cual se calculará una media de cada una de las tres ratios, evidenciando la perdida de productivad, incremento del coste capital, y la producción de existencias totales aproximándose a una cuantificación ponderada de la crisis hídrica mediante a una comparativa con los resultados encontrados con los del ejercicio económico correspondiente a 2022, antes de la coyuntura. Las empresas que integran el pool sobre el cual se realizará el análisis son: Henkell Freixenet, Raventos Codorníu, Grupo Bonpreu, Casa Taradellas, Damm S.A, Segura Viudas, Frit Ravich, Corporación Alimentaría de Guissona, Grupo Agora, Agroalimen, Costa Food Meat, Europastry, Valls Company, Grupo Agbar, Borges S.A, Nestlé España, Costa Brava Mediterranean Foods, Cobega S.A, Lipsa.

L’economia catalana en el context global: nova globalització, política industrial i dinàmiques institucionals
J. Plaza, J. Ribas, R. Xifré

Ramon Xifré's personal collection (2024). 1

Abstract
Aquest treball pretén identificar l'impacte en l’economia catalana d'un triple repte en el context global i també algunes de les oportunitats que apareixen en el nou escenari. En primer lloc, la globalització, una de les tendències econòmiques clau dels últims 40 anys, està en crisi. Les causes son múltiples, des de l’esgotament del model inicial i la crisi d’una “hiperglobalització descontrolada”, fins a xocs externs de diversa naturalesa com el populisme econòmic, el proteccionisme, l’impacte de la Covid-19 en la reformulació de les cadenes de valor, o canvis en les aliances geoestratègiques i els conflictes armats. En el marc europeu aquest context de crisi, a més, ha dut a una profunda reflexió sobre la pròpia pervivència del projecte d’integració tal i com s’ha conegut fins ara. Conceptes com el d’autonomia estratègica, la seguretat econòmica i, més recentment, el gir geoeconòmic del mercat únic, s’han convertit en referències constants tant en policy papers de la Comissió Europea com en la producció científica (Miró, 2023 o Herranz-Surrallés et al., 2024). En aquest mateix sentit, el recent informe Letta, encarregat pel Consell Europeu a qui fou President del Consell de Ministres d'Itàlia, marcarà l’agenda política europea 20242029 i posa l’èmfasi en la necessitat de dotar al Mercat Únic de les capacitats necessàries per a atacar amb prou energia i visió estratègica la transició en l’actual moment d’incertesa. En l’actual escenari geopolític i geoeconòmic mundial, en el qual es juga qui liderarà les tecnologies de la quarta revolució industrial —intel·ligència artificial, 5G, internet de les coses, robòtica, etc.— seria un error llegir la pugna entre els Estats Units i la Xina exclusivament com una guerra comercial. El comerç hi és, certament, però els elements tecnològics i de lideratge i influència hi tenen un paper molt important. Fins a la data, Europa no hi és en aquesta competició i clarament va una passa per darrera d’Amèrica i Àsia en tecnologia.

3r Congrés d'Economia i Empresa de Catalunya - Abstracts.

Abstract
4TH CONGRESS OF ECONOMICS AND BUSINESS OF CATALONIA: TOWARDS A MORE DIGITAL AND SUSTAINABLE ECONOMY (2024) THEMATIC AXIS: 6. THE SCIENCE AND INNOVATION SYSTEM AND THE CHALLENGE OF DIGITAL TRANSFORMATION Artificial intelligence and other emerging technologies TITLE OF THE COMMUNICATION: AI as a factor of social progress AUTHORS: Javier M. Asenjo Fernández (UOC), Manuel Murillo Rosado (UB) (both founding partners of the Conscienzia.org Association) JUSTIFICATION: AI is at the center of numerous debates due to its potential risks. However, it can also be a source of economic and social opportunities. OBJECTIVES - To reflect on the impact of AI on the economy, business and society. - To address the requirements for AI to become a factor of social progress. ABSTRACT INTRODUCTION AI is a set of programs that simulate human intelligence using massive data analysis and statistical prediction among other techniques. Its origin dates back to the 1950s with the work of Alan Turing (and others), although the real explosion came when the Chat GPT tool developed by the American company Open AI was presented in the open. A world of new possibilities and potential risks opened up globally. SOME KEY VARIABLES AFFECTED BY THE IRRUPTION OF THE IA - PRODUCTIVITY: there is talk of an increase of 15% per year on a sustainable basis. Many tasks can be done in half the time. - EMPLOYMENT: companies could consider doing without part of their workforce. Some jobs could disappear and new ones could emerge. - TIME: a surplus of time can be generated that can be devoted to other things, giving rise to new opportunities in emerging sectors. - EQUALITY: it can increase the GDP of the most developed countries (Macro) and of the most qualified companies and people (Micro). AI AS A FACTOR OF SOCIAL PROGRESS For this to happen, great progress would have to be made in order to meet a series of preconditions: - Governments and companies would prioritize ethical values when configuring algorithms, and people would be given primacy over machines. - Society would enhance the opportunities and minimize the risks of its use in strategic sectors: health, education, business, employment, ... - All social levels would be involved: political, business, trade union, ... in the search for a sustainable balance between jobs destroyed and those generated. - Critical thinking, verification of sources and reflection on the proper use of the application of AI would be promoted in education and citizenship. - Machines would pay taxes and social security contributions to compensate for the undesirable effects of their scalability. AI can make a difference as a factor of social progress in areas such as: - By sustainably increasing productivity, GDP can be improved and that differential could be devoted to improving services to the public - Improving individualized attention: to patients (health), to the customer (companies), to students (education), ... - With more quality time available (Kairos in Greek), people could devote it to areas they cannot now: taking care of people, enjoying the environment, art, leisure, learning, having a healthier life, creating, ...

Empreses, institucions, geopolítica [Eix 3: La musculatura del sistema empresarial català]
V. Ortún, M. Callejón

3r Congrés d'Economia i Empresa de Catalunya - Abstracts.

Abstract
Objectiu L’objectiu de la Comunicació es: (1) identificar i sintetitzar les bases actuals de les principals polítiques empresarials i industrials promogudes per la UE, Estats Units, organismes internacionals i governs català i espanyol, i constatar la seva aplicació la realitat del sistema productiu català; i (2) analitzar en quina mesura aquesta acció institucional pot influir en la millora de les dimensions de les empreses del sistema productiu català. Plantejament La petita dimensió relativa de les empreses catalanes (com de Espanya, Itàlia i altres països mediterranis) es un dels aspectes que es mencionen com una de les causes del feble creixement de la productivitat del sistema la última dècada. En la mesura que la dimensió recull característiques competitives de les empreses, constitueix un paràmetre d’interès. Les capacitats empresarials, la seva productivitat i competitivitat, depenen de diversos factors però, en primer lloc, de la qualificació de les persones, i en segon lloc de l’entorn institucional del que aquest treball s’ocupa. Altre factor destacable son les pertorbacions o “shocks” que l’entorn global projecte sobre els sistemes productius. Alguns shocks recents sobre la economia global provenen de la lluita geoestratègica i militar, en primer lloc, però també d’altres desenvolupaments com: (a) la concentració de poder en les grans plataformes tecnològiques; (b) les transformacions dels sistemes financers; i (c) l’acció dels grans inversors globals de capital privat que influeixen en la gestió de les empreses. L’enfrontament geoestratègic dona lloc a la disrupció de les cadenes de circulació d’inputs, i la resultant recomposició dels sectors productius. Y, sobretot, que els països occidentals volen recuperar el control d’una indústria en bona part transferida a Xina. Iniciatives internacionals Front al ampli escenari obert tant la OCDE com la Comissió Europea han intensificat el seu interès i les seves propostes per la millora de la qualitat i potència del conjunt d’empreses que han de operar en l’actual i futur terreny productiu i de relacions internacionals. Tant l’estructura empresarial com la composició sectorial serà afectada d’una manera o altre. Estats Units ha adoptat un conjunt de mesures de política industrial, que fins fa poc descartava i, per tant, els països europeus segueixen la iniciativa. D’altre banda, tant Estats Units com França, Alemanya i altres països europeus apunten la intenció de reforçar l’ indústria militar. Tècnicament seria una bona base de recuperació d’un sector manufacturer intensiu en recerca i coneixements. Socialment significaria el retorn del trade-off “guns or butter”. Enfoc i resultat esperat Aquest treball utilitza tres instruments principals d’anàlisi: primer, articles acadèmics; segon, publicacions rellevants de blogs, think tanks, i publicacions econòmiques nacionals i internacionals; i tercer, bases de dades de la OCDE, UE, Eurostat, INE, Idescat, Generalitat i altres publicacions governamentals i organismes internacionals. Finalment s’intenta valorar el grau d’ajust entre els instruments emprats pels governs i l’objectiu de millorar les dimensions empresarials com a element per adquirir competitivitat internacional.

The effect of particle properties on binary mixture segregation during blast furnace charging
R. Roeplal, Y. Pang, D. Schott

particles2023.

Abstract
Segregation is likely to occur during blast furnace charging since the iron ore mixture contains particles differing simultaneously in size, shape and density. However, predicting how the mixture components will be distributed is particularly difficult due to the combined effect of these differences. Although the Discrete Element Method has been used extensively to gain understanding of segregation during blast furnace charging, most research has focused on simple mixtures in which particles differ only in size. In this work, we investigate how size, shape and density differences simultaneously affect mixture segregation in radial and vertical directions of a charged layer using the response surface methodology. We found that size and density difference between the mixture components significantly affect both radial and vertical segregation while shape differences, especially the aspect ratio, are relatively less important.

3r Congrés d'Economia i Empresa de Catalunya - Abstracts.

Abstract
4TH CONGRESS OF ECONOMICS AND BUSINESS OF CATALONIA: TOWARDS A MORE DIGITAL AND SUSTAINABLE ECONOMY (2024) THEMATIC AXIS: 4. HUMAN CAPITAL AND THE FUTURE OF WORK/The future of work in a world governed by artificial intelligence. COMMUNICATION TITLE: "AI as a tool to help finding a job". AUTHORS: Javier M. Asenjo Fernández (UOC), Manuel Murillo Rosado (UB) JUSTIFICATION: AI is at the center of many debates. However, approaches are needed to take advantage of the opportunities and assess the risks of applying it to solve specific problems, in this case job search. OBJECTIVES: - Describe an overview of the process and a methodology for applying AI to job search and assess its risks and opportunities. - To share various practical experiences carried out in this context (Porta 22 of Barcelona Activa, public institute, private university, professional college). ABSTRACT INTRODUCTION AI is a set of computer programs that simulate human intelligence through statistical predictions and other techniques. Its origin dates back to the 50's with the work of Alan Turing (among others) and in November 2022, the open launch of the GPT Chat by the company Open AI is a catalyst for all previous contributions, opening a world of new opportunities and challenges at a global level. This paper proposes the use of this technology as an aid to find a job, with all the pros and cons that this entails. A global vision of the process and an applied methodology based on conversational chatbots, note takers, multimedia generators (images, videos and audio) is described. AREAS OF APPLICATION OF IA TO JOB SEARCH There are three areas where AI can bring value to job search. Firstly, improving knowledge: one's own (personal SWOT) and others' (market, sector, company, job position). Secondly, the sharpening of tools: CV, presentation communication (letter, mail, LinkedIn post, Whatsapp), portfolio (web, blog, social networks...), interview, tests and group dynamics. Finally it can be applied to continuous improvement through reflection on the preparation and execution of the process (feedback). PRACTICAL EXPERIENCES The authors have conducted several practical workshops in the context of this proposal. They have focused on training for the recruitment interview. Three phases have been worked on: script preparation (using chatbots), interview practice (with note takers for videoconferencing) and continuous improvement (chatbots and images). The aspects verified may be interesting for this area and extrapolated to others. The workshops have been carried out mainly for Barcelona Activa (in Porta 22) both face-to-face and virtual. Also for educational centers: Palau Ausit Public Institute (Ripollet) and Mediterrani University School (Barcelona). Finally, two conferences for the Association of Economists of Catalonia. CONCLUSIONS In the first place, the initial balance is positive, it has generated interest and participation. However, potential risks must be monitored: data protection, hallucinations, ethical aspects. Finally, this model is potentially transferable to other contexts and scalable to improve its impact on society.

Financial analysis for sustainable management of private forests. Example of Aleppo pine
D. Hornero, J. perramon

david ceballos's personal collection (2024). 2

Abstract
This paper presents a methodology for a financial and sustainable valuation of business forest management that also allows to improve the incentives to enhance public policies for prevention and conservation, with the case study of the Catalan Aleppo pine forests. Every summer and more recently due to the long drought, the situation of Catalan forests is news, with criticism for the results of public policies and the abandonment or bad exploitation of forests because there is a low proportion of this 41% of the Catalan area planned or certified for both environmental and economic sustainability, despite its economic and political importance. A paradigmatic case could be the Aleppo pine forests, one of the most representative of Catalonia, both for being a Mediterranean variety and for its extension, since it spreads easily through the open areas and its pyrophilic characteristic makes the fire also facilitates its "colonization". It is a type of forest that tends to be unmanaged and unexploited, despite its representativeness (almost 30% of the Catalan private forest area), although there are studies to help the sustainable management of these forests (Beltrán et al., 2011) and detected its potential benefit (Melo et al., 2017; and ICEA, 2019). However, the economic conclusions of these studies and the private maximization of public subsidies have led to a preference for non-exploitation, with perverse effects on fire prevention policies and protection and conservation of mature forests. However, with a broader view, especially from a financial analysis perspective (Ceballos and Perramon, 2021), it is possible to show both the economic viability of its business management, not only in contexts of very favorable prices, as well as the improvement of the effectiveness of public policies with stimuli is feasible if it is not based on the concept of immediate economic utility and other elements linked to sustainable finance are taken into account (Begemann, 2023). However, the results could be more ambitious in the recommendations of public instruments if there were a greater detail of the type of private forest owners in Catalonia as in other European cases (Ficko et al., 2019).

Construction Project Management & Green Building
B. Lakhani

Bhavinbhai Lakhani's personal collection (2018). 3

Abstract
This thesis studied the definition of a green building and the elements associated with the construction of sustainability. There are many rating systems available across the country both private and public. The most well-known is the LEED rating system developed by the United States Green Building Council. LEED has several rating programs now available. In this thesis, I will discuss why Green Building is more significant than conventional building and methods of Green Building like construction Phases. Conventional buildings produce high amounts of greenhouse gas, a large quantity of construction and demolition debris (which decrease landfill capacity), disturb natural resources, and consume much energy and water. Implementation of various simple and sustainable techniques practiced individually can help in many ways to create an environmentally friendly structure, consume minimal natural resources and at the same time be economical. This paper tries to study the Green Building construction method and innovative technologies that enable us to create a sustainable structure. It also includes design concepts of Green Building, methodology and materials requirements, and ideas and suggestions to create a checklist for a builder to refer to the various suggestions in every phase of construction of a general structure.

Ascens i responsabilitats de la professió d'economista
J. Tugores

Joan Tugores's personal collection (2024). 2

Abstract
Justificació L'ascens de la professió d'Economista va tenir una fita fa dos segles, amb la consagració de la denominació de “Economia Política” en els clàssics. Posteriorment la creació de les Associacions professionals d'Economistes com la British Economic Association (1885) i una titulació universitària específica de Economics en la universitat de Cambridge (1903) van ser altres fites en la consolidació social i professional dels Economistes, que va avançar en reconeixement amb la inclusió de l'Economia entre les disciplines amb Premi Nobel (1968-1969). Fa un segle, en 1924, Keynes va dedicar un llarg article amb motiu de la defunció del seu mestre Alfred Marshall, en què contenia la famosa descripció de la singularment “rara combinació de dons” que havia de reunir un economista. Què podem aprendre d'aquesta trajectòria d'interaccions entre realitats i idees de la nostra professió? Objectius En el moment d'eclosió de la professió, a principis del segle XIX, alguns problemes tenien cridaneres similituds amb els actuals: una època de ràpid canvi tecnològic que estava alterant les formes de treball, de vida i de relacions socials, generant el que avui diríem “nous models de negoci”. L'aprofitament dels guanys de productivitat de la Revolució Industrial va permetre als països occidentals accedir a una hegemonia econòmica i política, desbancant a la Xina i l'Índia…que en l'actualitat pretenen recuperar aquest lideratge. Els primers economistes van afrontar els problemes de distribució de la renda que es veia profundament alterada pels canvis tecnològics i les seves implicacions sociopolítiques. Un dels debats més presents era el paper de la liberalització comercial secundada, com la globalització, per uns mentre que uns altres expressaven les seves reticències davant els eventuals problemes en l'accés a “subministraments estratègics”. Moltes d'aquestes qüestions de fons tornen avui a ser presents de forma accentuada: impactes del canvi tecnològic, especialment la intel·ligència artificial, amb formulacions de Ricardo que anticipen desenvolupaments recents de Acemoglu, debats sobre fragmentacions i sobre pugnes geoestratègiques i les seves implicacions, així com la distribució dels “dividends” de la globalització i del canvi tecnològic. Els temes demogràfics i els factors limitatius del creixement – ara amb les preocupacions mediambientals – tenen així mateix arrels i tradició. Gestionar “trade off”, avaluar cursos d'actuació alternatius, adaptar-se de manera creativa a noves i complexes realitats…alguns dels trets que singularitzen als economistes tornen a estar en primer pla Resultats/Conclusions a treballar Les responsabilitats creixents dels economistes com a professió, davant el conjunt de la societat, adquireixen especial rellevància en moments de complexitats i perplexitats. Les experiències acumulades així com la capacitat d'adaptació a noves realitats i a la conformació de potencials escenaris de futur són actius importants perquè els economistes siguin un “pont sobre aigües turbulentes” en aquests delicats moments, en què aquests ponts són singularment rellevants quan més turbulentes siguin les aigües…

Piezocatalysis with Optimized Turbulent Flow in Hydro Turbine for Eutrophication Remediation
E. Zhao, A. Huenger

J. of Dawn. R. (2024). Vol. 6, 5

Abstract
Eutrophication affects 65% of coastal and 53% of freshwater regions in the US but no scalable cyanobacterial degradation methods exist. Piezocatalysis harnesses mechanical energy to produce reactive oxygen species (ROS) in water, which degrade organic pollutants by oxidation without generating toxic residues. This study designed a novel hydro-turbine using bluff bodies that maximize kinetic flow energy available for aquatic remediation via piezocatalysis. MoS2-doped films exhibited first-order ROS chain reaction production when agitated in Anabaena (20 μg/L), and has potential to inhibit cyanobacterial positive feedback growth by converting nitric products into reactive nitrogen species. The inverted piezo-active flag model was computationally optimized to enhance polarization with turbulent energy and ensure rapid charge dispersion with flow-induced vibrations. The 90° upstream triangle yielded maximum coefficients by effective flow separation (12.6 drag, 18.6 lift) and a flag length ratio of 0.75 was optimal while avoiding canceling zones. The optimized piezocatalytic hydro-turbine design yielded 78% remediation under 800gph for 60s (p=0.032). A minimum flow speed was identified by energy/order to be 0.5m/s, with 0.7W/(1g MoS2). Application depth of 0.3m-2m was identified with cyanobacterial concentration, turbulence needed for crossflow effectiveness, and speed; conditions are within industrial scalability standards. Chain reactions allow the remediation of still-water and high-volume downstream regions through tributaries. In the future, the device can be studied in environments with varying meander speeds and upstream ROS exposure times. The device presents a potential industrial eutrophication treatment applicable in ~93% of fluvial environments.

USSD 2014 - Presentation - Robustness
. DISEG, P. Torino, A. Calvi

USSD Conference on Dams - 2014

Abstract
Robustness plays a relevant role in the capacity of a structure to sustain abnormal loads or to deal with unexpected events with large effects, such as explosions and terroristic attacks. Such situations on dams may have extremely large consequences. For buildings, the design approach that best implements robustness concepts is represented by the so called “Consequence Based Design”: even if nothing is known about the cause, selective element removals and extreme load on the structure are modeled, and their effects are determined with respect to progressive collapse and damage arrest. In the paper we try to set-up a “Consequence Based Assessment” of a typical example of a gravity dam built between the ‘30s and ‘40s of the last century in the northwestern Italian Alps. A simplified model of the structure is adopted. Removal of parts of the dam cross-section is assumed to occur: the effects of the extent of damage is discussed on the bases of the tension generated within the body of the dam

Construction Project Management and Green Building
B. Lakhani

J. of Dawn. R. (2024). Vol. 6, 4

Abstract
'''This thesis studied the definition of a green building and the elements associated with the construction of sustainability. There are many rating systems available across the country both private and public. The most well-known is the LEED rating system developed by the United States Green Building Council. LEED has several rating programs now available. In this thesis, I will discuss why Green Building is more significant than conventional building and methods of Green Building like construction Phases. Conventional buildings produce high amounts of greenhouse gas, a large quantity of construction and demolition debris (which decrease landfill capacity), disturb natural resources, and consume much energy and water. Implementation of various simple and sustainable techniques practiced individually can help in many ways to create an environmentally friendly structure, consume minimal natural resources and at the same time be economical. This paper tries to study the Green Building construction method and innovative technologies that enable us to create a sustainable structure. It also includes design concepts of Green Building, methodology and materials requirements, and ideas and suggestions to create a checklist for a builder to refer to the various suggestions in every phase of construction of a general structure. '''Key Words: '''Green Building, Construction of Sustainability, LEED, Minimal Natural Resources, and Sustainable Structure.

Structural and Seismic Design of a Steel Staircase using FEM in compliance with Italian Legislation
A. Calvi

Collection of Engineering (2024). 2

Abstract
Structural analysis is conducted by the displacement method for evaluation of the stress-strain state induced by static loads. The analysis is conducted by the modal analysis and acceleration response spectrum method for the evaluation of the stress-strain state induced by dynamic loads (including seismic loads). Structural analysis is carried out using the finite element method. The above method is based on the schematization of the structure into elements connected only at a set number of points called nodes. The nodes are defined by the three Cartesian coordinates in a global reference system. The unknowns of the problem (within the displacement method) are the displacement components of the nodes referred to the global reference system (translations according to X, Y, Z, rotations around X, Y, Z). The solution of the problem is obtained by a system of linear algebraic equations whose known terms consist of the loads acting on the structure appropriately concentrated at the nodes.

ANALYTICAL INTERPRETATION OF HYDRODYNAMIC PRESSURE ON DAMS
A. Calvi

Alessandro Calvi's personal collection (2024). 12

Abstract
Earthquakes pose a significant threat to dams and other reservoir structures. Beyond the ground shaking itself, the dynamic interaction between the earthquake ground motion and the water in the reservoir creates a phenomenon known as hydrodynamic pressure. This pressure can significantly exceed the static hydrostatic pressure that the dam is typically designed to withstand. Understanding and accurately predicting hydrodynamic pressure is crucial for ensuring the safety and stability of dams during seismic events. This paper provides an excursus on the literature present on this topic and delves into the formulation included in the Ministerial Decree of 1982 developing in detailed calculation steps and thus determining in closed form the resultant of the pressures and its point of application.

PROGRESSIVE COLLAPSE AND ROBUSTNESS OF FRAMED STRUCTURES: SIMULATION AND DESIGN
M. E., C. A., C. B.M., A. Calvi

Alessandro Calvi's personal collection (2024). 1

Abstract
We present a framework to investigate progressive collapse and robustness of 2D framed structures, subjected to multiple column removals. Progressive collapse is first simulated with an algorithm based on the Discrete Elements. The possible collapse mechanisms emerging from the simulations constitute the input for an analytical model. The model takes into account the dynamics of the response to the sudden initial damage and, under the hypotheses of ideally plastic or perfectly brittle ruptures, provides upper and lower bounds for the collapse loads and for the progressive collapse resistance. Closed form expressions are obtained, that can be valuable for robustness-oriented design. A novel concept of hierarchy in robustness capacity design emerges, which partly conflicts with anti-seismic capacity design. Strategies of compartmentalization and the influence of the position of the initial damage within the frame are discussed, also taking into account the impacts between falling rubble and horizontal floor slabs.

The topic addressed in this research was about dating violence, talking about it from the face-to-face point of view and the digital point, that is to say online in the love relationships of young people; specifically this research was applied for the LGCH19 group of the Technological University of Queretaro, in which there are a total of 32 students, of which nine of them are men and twenty-three women, students of the Bachelor's degree in human capital management. The main general objective of the present study was to make known the most common online and offline dating violence factors, from a theoretical analysis, so that more young people can identify it early. To achieve this objective it was necessary to find out if young people knew about the topic, although many of them said they knew about the topic of dating violence offline, most of them did not identify the issue of violence online or to some extent it is a topic that they had "normalized" within their social circle, or to which they simply did not pay the necessary attention or importance, so to speak. In addition to making known the factors of each of the types of violence: online, offline, physical, psychological, emotional; and how these can affect emotionally and therefore affect the student or work life of those who experience it.

(2016). IJIRST - International Journal for Innovative Research in Science & Technology

Abstract
In present era, there are so many buildings which collapse fully or partially due to lake of maintenance, improper construction method and material or even due to earthquake. They need repairing to make them safe. Repair are always neglected or delayed by many people in most of building owing to lack of awareness and financial ability and so it leads to major hazards. Hence, it is needed proper repair and reconstruction application. In this project we have more focus on repairing on building which have required maintenance, because most of problem occurs after certain life of building. In addition, we have also focus on repairing of that sort of structure which have more than of their certain life and which has affected by some disaster like earthquake, flood, etc. At last, we will suggest some useful innovative materials and its application, how to apply on damage part, which would ultimately improve the strength of the structure.

Abstract
In Construction Industry cost is amongst the major considerations throughout the Project Management life cycle and thus can be regarded as one of the most important parameter of a project and the driving force of project success. Despite of its proven importance it is not uncommon to see a construction project failing to achieve its objectives within the specified cost. Cost overrun is a very frequent phenomenon and is almost associated with nearly all projects in the construction industry. In this paper different type of cost are enlisted and due to the effect of cost overruns enumerated in building projects. Effects Cost overruns are decrease in the building projects so, different methods are used the analysis cost overruns factors are give the top ten ranks.

Research on the influence and characteristics of ocean waves on the stability of near-surface UUVs
C. Zhou, J. Wang, H. Li, Y. Li, P. Sun

Rev. int. métodos numér. cálc. diseño ing. (2024). Vol. 40, (2), 17

Abstract
Existing experimental methods or traditional numerical methods struggled to separate the resistance caused by a vessel's movement and the impact of waves. However, the impact of waves significantly affected the stability and safety of Unmanned Underwater Vehicles (UUVs). To summarize the influence of different attitudes and sea conditions on ocean wave impact, this work first proposed a method to separate the influence of ocean waves. This method used the unsteady finite volume method to analyze the forces on the vehicle in both wave and calm water environments. It also employed a separation formula to isolate the wave impact based on a separation equation. Then, this work selected a specific UUV as the research subject and applied this method to separate the wave impact under various attitudes and sea conditions. The results were then reconstructed. Finally, the effects of various factors on wave impact were summarized, including wave height, wave period, pitch angle, heading angle, velocity, and diving depth.

The convergence of rising power efficiency and the need for miniaturization has underscored the significance of creating heat sink configurations that are not only efficient but also capable of maintaining performance without necessitating expansion. This review article provides an exhaustive examination of recent developments in heat transfer enhancing methods, with a specific emphasis on a range of heat sink configurations and design approaches. Thermal efficiency expressed as a pin termination circular and pin fin square is assessed in the present research, Pin Fin Elliptical, and Channel Heat Sink designs. Comparative results indicate that Pin Fin Circular exhibits good performance, while Pin Fin Elliptical shows better results. The numerical analysis includes considerations of thermal performance, surface area, manufacturing complexity, and 2D models. Pin Fin Circular, with its efficient heat dissipation and moderate complexity, emerges as a promising option. The paper evaluates the applicability of additional manufacturing processes, including EDM, etching, casting, extrusion, and machining, for prototyping and mass production. A detailed investigation of manufacturing methods shows that, contingent upon the method used, Pin and Channel designs possess unique merits and demerits. In addition, the study emphasises the importance of cost aspects during the design process. Also, the assessment examines the current status and potential future advancements of heat sink technology, placing particular emphasis on the necessity for unique designs, materials, and versatile manufacturing methods. The incorporation of Nano fluids technology and the exploration of structural design perspectives are identified as potential avenues for future research. This work aims to provide a comprehensive overview of recent developments in heat sink technology, offering insights into thermal performance enhancement and guiding future studies in this critical field.

Design and structural analysis for a camber-morphing wing with deformable truss
S. Cao, S. Zhao, Y. Ni, J. Jiao

Rev. int. métodos numér. cálc. diseño ing. (2024). Vol. 40, (2), 11

Abstract
A camber-morphing wing based on a deformable truss is proposed in this paper. And then the structural analysis of the proposed camber-morphing wing is achieved. Compared with the existing concept of camber-morphing wings, the deformation mode of this wing is easier to manufacture and implement in engineering. Due to the fact that the wing is driven by multiple motors, it has the characteristic of multiple degrees of freedom in camber-morphing, which can achieve various deformation controls. Establishing corresponding finite element models, the deformation ability under different driving conditions is simulated. The results indicate that compared with driving short metal wires, driving long metal wires results in a greater degree of trailing edge deflection due to a greater driving force. Based on finite element analysis of deformation capability, the camber-morphing wing exhibits satisfactory deformation capability. Furthermore, based on the analysis of load-bearing capacity, it is indicated that the camber-morphing wing has sufficient load-bearing capacity.
