This essay presents some main features of the kick-off of 5G in India and Brazil extracting implication for Global South catchup. Based on some main neo-Schumpeterian contributions on long-waves, long-cycles, and catch-up, attention has been paid to the interstate competition between the US and China, the global pressures and linkages of the Indian and Brazilian National Systems of Innovation, and the development of key infrastructures and productive capabilities by the domestic and multinational firms involved in the kick-off of 5G. Two main Global South cases capturing the interrelated geopolitical and technological tensions of the 21st century transitioning capitalism are discussed.
Unusual Association of Skipjack Tunas Katsuwonus pelamis and a Longline Vessel
Gonzalo Mucientes,Nair Vilas-Arrondo 한국해양과학기술원 2021 Ocean science journal Vol.56 No.1
Skipjack tuna were observed for the first time swimming in front of the bow of a fishing vessel during a tagging campaign in the North Atlantic. Video recordings show how tuna adapted their speed and direction to the vessel, using the pectoral fins to move from top to bottom and back and forth across the bow of the ship. We discuss the potential drivers of this behaviour.
Rising China’s ‘Offensive’ in Latin America and the U.S. Reaction
Gonzalo Paz 경남대학교 극동문제연구소 2006 ASIAN PERSPECTIVE Vol.30 No.4
The year 2004 will be remembered as one in which an increasingly confident China jumped into Latin America, a geopolitical and geoeconomic space always considered by the United States as its "backyard.” In 2005 and 2006 that policy continued and was sustained. The central questions addressed in this article are: Why is China executing an economic and diplomatic offensive in Latin America? Is a rising China challenging U.S. hegemony over the Western Hemisphere? And, how has the United States responded to these actions? The main argument advanced here is that there is an economic rationale behind China’s new foreign policy toward Latin America, and that the theses about an ideological or a strategic rationale must be rejected. China’s goal is to secure the provision of agriculture products, minerals, and especially oil. China is not trying to challenge American hegemony in Latin America, but it is the first Asian country to push enough to concern American analysts. The article will provide empirical evidence of the new level and quality of China-Latin America relations.
Economic Reform Prospects for the Maghreb
Gonzalo Escribano 부산외국어대학교 지중해지역원 2009 The Mediterranean Review Vol.2 No.1
After the successes in macroeconomic stabilization, the Maghreb countries (Algeria, Lybia, Morocco and Tunisia) have pursued the implementation of economic and administrative reforms since the 1980s in order to liberalize the economic system and enter a phase of sustained growth acceleration. This has led to tensions between macroeconomic stabilization and modernization in the region. The present article focuses specifically on the prospects for economic policy reform in the Maghreb and the channels through which it could proceed in the presence of the major economic crisis we are experiencing. The article argues that under current economic circumstances, prospects for microeconomic reform in the Maghreb critically depend on the policy-makers capacity to maintain macroeconomic stability and to anchor microeconomic and institutional reforms. It also put forward that the most effective channel to anchor structural reforms may be to signal commitment to convergence towards the economic institutional setting developed by the European acquis communautaire. Finally, it underlines that the EU’s role should be not just to avoid recurring to protectionism, but to deliver sufficient incentives to support economic reformist governments in completing the reform agenda. This also may prove much harder to introduce into EU Member States’ preferences under the current negative economic expectations.

Fuel cell systems are being diligently developed owing to their highly efficient power production with significantly less environmental impact. However, for proper operation of the fuel cell stack, i.e., without CO poisoning of the Pt anode, the hydrogen produced by the steam reforming of hydrocarbons or alcohols must contain less than 100 ppm CO. For automobiles such as fuel cell electric vehicles (FCEV), the two-stage purification process, including the water-gas shift reaction (WGS) reaction and the CO catalytic preferential oxidation reaction (COPROX), is commonly used due to its simplicity and effectiveness. An efficient COPROX uses a monolithic catalyst reactor with a compact volume, low-pressure drops, and fast dynamic responses. Besides, the catalyst washcoat must show high activity and selectivity for CO oxidation to reduce H2 consumption. Pt-based catalysts have shown high activity, selectivity, and stability, especially in low-temperature ranges, features that have made them popular for COPROX. This work presents thermodynamic modeling under adiabatic and isothermal conditions of a monolithic COPROX reactor using Pt-Fe/γ-Al<sub>2</sub>O3 washcoat in H2-rich streams capable of feedings fuel cell stacks. The modeling aims to research the effects of the variation of inlet conditions at steady-state operation. A simulation validation is presented in a range of 363-553 K based on experimental results found in the literature. The simulation results demonstrated that the catalyst activity increased according to the inlet temperature, achieving the highest CO conversion at 512 K in isothermal condition (89%) and 442 K in adiabatic condition (34%). COPROX reactor operations at higher temperatures undermined catalyst performance in all cases, an effect attributed to the reverse water-gas shift reaction (RWGS); RWGS produced more CO at such high temperatures. Furthermore, the maximum CO conversion was improved at low CO/O<sub>2</sub> ratios in the feed stream, especially with low CO concentration.

Stress at work and in the family is a very common issue in our society that generates many health-related problems. During recent years, numerous studies have sought to define the term stress, raising many contradictions that various authors have studied. Other authors have attempted to establish some criteria, in subjective and not very quantitative ways, in an attempt to reduce and even to eliminate stressors and their effects at work and in the family context. The purpose of this study was to quantify so-called cushioning variables, such as control, social support, home/work life conciliation, and even sports and leisure activities, with the purpose of, as much as possible, reducing the negative effects of stress, which seriously affects the health of workers. The study employs data from the Fifth European Working Conditions Survey, in which nearly 44,000 interviewees from 34 countries in the European Union participated. We constructed a probabilistic model based on a Bayesian network, using variables from both the workplace and the family, the aforementioned cushioning variables, as well as the variable stress. If action is taken on the above variables, then the probabilities of suffering high levels of stress may be reduced. Such action may improve the quality of life of people at work and in the family.
Hurricane vulnerability model for mid/high-rise residential buildings
Gonzalo L. Pita,Jean-Paul Pinelli,Kurt Gurley,Johann Weekes,Steve Cocke,Shahid Hamid 한국풍공학회 2016 Wind and Structures, An International Journal (WAS Vol.23 No.5
Catastrophe models appraise the natural risk of the built-infrastructure simulating the interaction of its exposure and vulnerability with a hazard. Because of unique configurations and reduced number, mid/high-rise buildings present singular challenges to the assessment of their damage vulnerability. This paper presents a novel approach to estimate the vulnerability of mid/high-rise buildings (MHB) which is used in the Florida Public Hurricane Loss Model, a catastrophe model developed for the state of Florida. The MHB vulnerability approach considers the wind pressure hazard exerted over the building's height as well as accompanying rain. The approach assesses separately the damages caused by wind, debris impact, and water intrusion on building models discretized into typical apartment units. Hurricane-induced water intrusion is predicted combining the estimates of impinging rain with breach and pre-existing building defect size estimates. Damage is aggregated apartment-by-apartment and story-by-story, and accounts for vertical water propagation. The approach enables the vulnerability modeling of regular and complex building geometries in the Florida exposure and elsewhere.
