En la planta Damují de la provincia de Cienfuegos, Cuba, se produce una gran parte del papel kraft empleado en las cajas de cartón que se usan como envases y embalajes. Esta empresa ha presentado diversos problemas con las autoridades ambientales por la contaminación que genera a su río homónimo, hacia el cual vierten sus efluentes líquidos y por las emisiones de gases y el consumo excesivo de su caldera de generación de vapor. El proceso de producción estaba sujeto a la introducción de tres posibles mejoras: Cierre del circuito de agua, el cual permitiría reutilizar el agua en el proceso reduciendo su consumo actual y el uso de aditivos químicos, los cuales también se recuperan; cambio de la caldera de generación de vapor por una más eficiente, lo cual disminuiría la cantidad de vapor generado por unidad de combustible; la otra posible alternativa era la reactivación del sistema de residuales de la planta, el cual se encontraba en muy mal estado. El presupuesto de la entidad no era suficiente para llevar a cabo todas estas mejoras y se requería priorizarlas. Es por ello que se debieron aplicar estudios de Análisis de Ciclo de Vida (ACV) y la simulación del proceso para evaluar técnica, económica y ambientalmente las alternativas. Según esta investigación se pueden ejecutar, el cambio de la caldera y la reactivación del sistema de residuales o el cierre del circuito de agua, decidiéndose por esta última según los criterios planteados.

This paper presents a structural equations model (SEM) that measure the Urban Quality of Life (UQoL), taking as reference Cienfuegos's city (Cuba). The objective is to determine the variables that influence the UQoL, to develop a procedure that allows the design of two models: one from the objective dimension and the other from the subjective dimension of this concept. As main results a model of relations of management indicators, given by local decision makers and another model that relates perception indicators, given by citizens is showed. The comparison between these models makes it possible to generalize that variables such as health, housing and income are determining factors in the UQoL of Cienfuegos's city. [ABSTRACT FROM AUTHOR]

In April 2023, a group of 1 administrator, 5 faculty, and 20 students from the University of Louisiana Monroe (ULM) traveled to the Dominican Republic to participate in an interdisciplinary service-learning project lasting six days. Disciplines involved included pharmacy (2 faculty members and 9 students), physical therapy/kinesiology (1 faculty member and 5 students), social work (1 faculty member and 4 students), and political science (1 faculty member and 2 students). The home base for the group while in the Dominican Republic was Abba’s House Children’s Center, a nonprofit Christian organization tasked with feeding, educating, and providing limited medical care to approximately 125 children living in the barrio of Cienfuegos. During the service-learning experience, ULM students engaged in various service and learning activities tied to their programs of study. Students and faculty completed the Community Service Attitude Scale (CSAS) before and after the service-learning experience (Schwartz & Howard, 1977). A total of 14 students (70%) submitted both a pre- and post-trip CSAS survey. There was a significant improvement in scores for 21 out of 25 items on the CSAS. This international interdisciplinary service-learning program positively impacted students’ attitudes toward community service including awareness of global needs. [ABSTRACT FROM AUTHOR]

The creep failure of the tubes of the vapor generators are present in the almost of the thermoelectric power stations, for this reason, a great quantity of investigators from all over the world is being in charge of the study of the useful life for creep in the tubes of the generators of vapor with the purpose of to minimize the mishaps and to reduce the expenses. The direct and immediate consequence, when failure tubes exist, it is the progressive increase of the quantity of water demineralized that feeds to the boilers that which is explained because this flaws in the tubes produce flight or escape of water that it doesn't finish the process of formation of vapor. Therefore, the mishaps cause losses for unavailability and other losses associated with the repair of the failure in question, diminishing the efficiency of the installation. In the Thermoelectric Power Station "Carlos Manuel de Céspedes" of Cienfuegos is quantified for separate all the expenses in that they are incurred. In this paper it is sought to consider different economic aspects that should be included in the valuation of the cost of the flaw of a tube of the wall of water. Once one has certain the unitary cost of a flaw can be considered to as much as it has ascended the expenditure in foreign currency for concept of flaws tubes of the walls of water, for each one of the Japanese units, in those more than 30 years that one has registered these mishaps.

Sargassum fluitans y Sargassum natans are holopelagic brown macroalgae that can aggregate to form extensive floating mats on the surface of North Atlantic (Sargasso Sea). The present paper describes the occurrence of an excessive drift of Sargassum fluitans in the East coast of Cienfuegos province, central-southern region of Cuba, in May of 2012. Most impact of the drift by mechanic effect on the coast was reported in the touristic sector. Atypical meteorological conditions were observed during the Sargassum drift. [ABSTRACT FROM AUTHOR]

The paper provides a prospective study of food industry companies in the provinces of Villa Clara and Cienfuegos, with a competitive vision in five years. In the prospective solution combines the established methods of future scenarios and SWOT analysis, with the Complex Analysis Processes under uncertainty. The possibilities of producing citric acid products derived from sugar cane and the effect of scale sizes in these productions are studying. Finally, several examples of application are shown.

The Bamboo plants have fascinated growers and have motivated several specialists in their study due to their beauty and many applications. They are mostly originated in tropical and subtropical regions of the planet. In Cuba, the level of endemism is low and there are primarily herbaceous size species. For this reason, tree-sized woody species present in Cuba were introduced mainly by the Harvard Botanical Garden, Cienfuegos Botanical Garden today. The main objective is to study the economic potential and adaptation under the climatic conditions of Cuba, overlooking the extensive use of these resources. In previous years the use of these species has only been for emerging and craft work and its extension in reforestation plans has been limited. In 1989 began the first steps to encourage the cultivation and application of this wonder plant in our country. In this paper we show the results achieved in the propagation of bamboo in twenty years of work under different conditions. This helps to diversify the results in several provinces of the country with prospects for a local bamboo economy. Besides, it encourages job opportunities, satisfaction of many basic needs and import substitutions. [ABSTRACT FROM AUTHOR]

The present paper was developed in the Centro Provincial de Capacitación, Experimentación and Extensión Agropecuaría La Colmena MINAGRI-CETAS, in the period which includes December 1999 to April 2000. This research studies the behaviour of common bean variety prospected in different municipalities of the province by means of the execution of a field experiment using a design of block at random evaluating the varieties of common beans (Phaselous vulgaris L.) Seven Nations (r), Cejita (r), American (n), CC-25-9 (n), CC-25-9 (b). The two latter ones were taking like samples of comparison with the goal of characterizing them in the conditions edafoclimatic in the province. The height of the plants, the phenology of the growing, the components of performance and final performance were evaluated. The varieties which were found by our farmers were premature (85 days) in relation to the varieties recognized as commercial ones. Considering the performance the variety of Seven Nations and Cejita showed high values but they were not exceeded by the variety CC-25-9 (n). Taking into account the conditions in which this research was developed, all the varieties obtained good economic results and it was also perceived the susceptibility of the variety Cejita to the attack of the Roya.

Through the means of ethnographic fieldwork, carried out during seven extended visits to the Cuban capital of La Havana and Cienfuegos between 2007 and 2017, this article aims to investigate how the concept and the ultimate purpose of 'work' have been changing in contemporary Cuba, due to the set of reforms recently enacted in the labor market. Stemming from Graeber considerations on the "politics of value", I analyze how, in the Cuban traditional planned economy, 'work' was the core of the social project whose aim was not to produce profit but to ensure basic needs to the whole citizenry. Finally, I seek to argue how, in more recent times, work is the nest of a complex values' transformation and a turning point in joining the Marxist-Leninist social project. [ABSTRACT FROM AUTHOR]

The wars of independence in Cuba (1868–1898) catalyzed social change, as women, people of African descent and workers challenged existing social hierarchies. With the inauguration of American military rule (1899–1902), however, Cuban political elites had to preserve order in order to demonstrate their fitness for self-government by performing an elusive and changing notion of civilization. Military authorities and local elites promoted diverging visions of social order, a key determinant of civilization, through the expansion of public instruction and the manipulation of its curriculum. The project of socially appropriate education aimed to create future citizens who knew their place in society, though women, workers, and people of African descent continuously challenged the parameters of this elite policy. On the international stage at the 1901 Buffalo Exposition, conservative local educational administrators silenced this dissent to showcase their civilizing achievements based on gender-differentiation because official racial segregation became socially unacceptable and politically dangerous in Cuba. With a geographic focus on Cienfuegos, this research shows that local elites took advantage of the imperial project of the international exposition to bolster their own political preeminence by claiming a unique variant of civilization based around female domesticity as a symbol of social order.
