On thermoeconomics of energy systems at variable load conditions: integrated optimization of plant design and operation
2007
Abstract Thermoeconomics has been assuming a growing role among the disciplines oriented to the analysis of energy systems, its different methodologies allowing solution of problems in the fields of cost accounting, plant design optimisation and diagnostic of malfunctions. However, the thermoeconomic methodologies as such are particularly appropriate to analyse large industrial systems at steady or quasi-steady operation, but they can be hardly applied to small to medium scale units operating in unsteady conditions to cover a variable energy demand. In this paper, the fundamentals of thermoeconomics for systems operated at variable load are discussed, examining the cost formation process an…
Interviews with Community Healthcare Registered Nurses in Norway: Examination Practices and Clinical Evaluation Processes
2021
Abstract Aim This study describes the examination practices and clinical evaluation processes that Registered Nurses in Norway perform in the community healthcare sector. Design A qualitative exploratory design. Methods Twenty interviews were conducted with Registered Nurses employed in the community healthcare sector in Norway. The data were analysed using a thematic analysis. Results We found four major themes: (1) evaluations are embedded in nurses’ daily work, (2) significance of a Registered Nurse's clinical competency, (3) different tasks require various roles and (4) access to resources and equipment. Registered Nurses possess several skills in a range of different examination techni…
Hacia una mayor autonomía en la construcción de identidades de género partiendo de la mirada crítica de Mernissi y el Hachmi
2021
[Resumen] En este trabajo destacamos dos problemas en la construcción de identidades de género por parte del alumnado adolescente: la escasa incorporación de contribuciones culturales femeninas en manuales escolares y cánones literarios, y la imagen distorsionada de las mujeres de origen marroquí instaurada en el imaginario colectivo, que oculta sus manifestaciones de autonomía y perjudica las relaciones interculturales. Nuestro objetivo fundamental es realizar un análisis discursivo de cuatro títulos de Fatema Mernissi y Najat El Hachmi en relación a la identidad de género para establecer las claves del modelo subyacente y valorar, a continuación, las posibilidades de explotación didáctica…
Spain: a decentralised health system in constant flux
2009
The Spanish healthcare system is one of Europe’s most efficient, but urgent reform is needed if it is to cope with changing demands and rising costs, argue Jose M Martin-Moreno and colleagues
The influence of eye movements on the temporal features of executed and imagined arm movements.
2007
The very close coordination between eye and hand indicates that eye movements are parts of the neural processes underlying the planning and control of arm movements. Eye movements are fundamental during observed actions and play a functional role in visual mental imagery. However, the role of eye movements during imagined actions is still unknown. Here, we report the timing features of eye and arm pointing movements for nine healthy participants in four conditions: Executed movements with orientation saccades (Eyes Free) or with no saccades (Eyes Motionless), and Imagined movements with Eyes Free or with Eyes Motionless. The first result was a facilitation effect of saccades upon both execu…
Researches Regarding the Usage of Titanium Alloys in Cranial Implants
2014
In the last few decades, the concept of flexible manufacturing has started to gain more and more attention, as an adaptation of production methods to the increasingly varied demands by customers. Therefore, new procedures have been introduced as alternatives to the classical ones, a very promising one being incremental forming [. A possible application for this new procedure, targeted by the authors of this paper, is the manufacturing of custom-shaped prosthetic parts for use in various areas of human medicine. Such prostheses can have a functional role, when they target the replacing of a functional component of the human body, or an esthetic role, when they target the solving of problems …
Model of a Constructive Fuctional Optimization of the Cardan Cross
2015
This paper aims to establish an optimization model using the Ansys program, and taking into account the specific constraints depending on the functional role of the specific area. We present certain calculation parameters applied to the cardanic transmission of the Dacia, this cardanic transmission being considered an optimization model. The entire cardanic transmission was analyzed, resulting that the cardan crosses are parts which are strained the most, and that is why it will be here that the optimization will be focused, in terms of minimizing the Von Mises stress.
Insects’ potential: Understanding the functional role of their gut microbiome
2021
The study of insect-associated microbial communities is a field of great importance in agriculture, principally because of the role insects play as pests. In addition, there is a recent focus on the potential of the insect gut microbiome in areas such as biotechnology, given some microorganisms produce molecules with biotechnological and industrial applications, and also in biomedicine, since some bacteria and fungi are a reservoir of antibiotic resistance genes (ARGs). To date, most studies aiming to characterize the role of the gut microbiome of insects have been based on high-throughput sequencing of the 16S rRNA gene and/or metagenomics. However, recently functional approaches such as m…
Ephaptic coupling of myelinated nerve fibers
2001
Numerical predictions of a simple myelinated nerve fiber model are compared with theoretical results in the continuum and discrete limits, clarifying the nature of the conduction process on an isolated nerve axon. Since myelinated nerve fibers are often arranged in bundles, this model is used to study ephaptic (nonsynaptic) interactions between impulses on parallel fibers, which may play a functional role in neural processing.
Computing Metal-Binding Proteins for Therapeutic Benefit
2021
Over one third of biomolecules rely on metal ions to exert their cellular functions. Metal ions can play a structural role by stabilizing the structure of biomolecules, a functional role by promoting a wide variety of biochemical reactions, and a regulatory role by acting as messengers upon binding to proteins regulating cellular metal-homeostasis. These diverse roles in biology ascribe critical implications to metal-binding proteins in the onset of many diseases. Hence, it is of utmost importance to exhaustively unlock the different mechanistic facets of metal-binding proteins and to harness this knowledge to rationally devise novel therapeutic strategies to prevent or cure pathological st…
