Published: July 2017

Este artículo presenta el estudio para conseguir el modelo de un motor-generador (planta), se emplean métodos gráficos o paramétricos que nos servirán como herramientas para representar dicho sistema de forma matemática. Se han adquirido muestras a través de una DAQ del comportamiento del sistema ante un escalón y una señal PRBS, los datos obtenidos se procesaron a través del software MATLAB y el toolbox IDENT, donde por medio de criterios de selección se obtiene un modelo ARX. Las técnicas estudiadas fueron: identificación paramétrica con la aplicación de una señal PRBS y estructura de modelo ARX e identificación no paramétrica con la aplicación de métodos gráficos. Luego se realiza una comparación entre los datos reales con los diferentes métodos aplicados y se obtiene que las respuestas son muy similares. La identificación de sistemas nos sirve para construir modelos matemáticos de sistemas dinámicos basándonos en los datos observados, con lo cual se tiene un conjunto de técnicas para levantar un proceso.

Déficit agroalimentario de la provincia de Santa Elena
Authors: Burgos Vera Bruno , Suárez Rodríguez Otto 
Published: July 2017

El desarrollo de una nación se cimienta principalmente en el bienestar de su colectivo a través de una redistribución equitativa del ingreso, una mayor productividad y un incremento de las oportunidades laborales; la agricultura juega como tal un rol fundamental para la economía y nutrición del colectivo. Sin embargo, las políticas de estado se han orientado generalmente hacia otros sectores como la industria, comercio y minería. Si a esto se agrega las inadecuadas inversiones en investigación científica, capacitación y transferencia de recursos y tecnología, se tiene como resultado una baja productividad y limitado aprovechamiento de los recursos que ofrece la agricultura poniendo en riesgo la soberanía alimentaria del país, objetivo estratégico fundamental consagrado en la Constitución. Esta situación es más crítica a nivel provincial, en que provincias como Santa Elena no cuentan con los recursos adecuados y suficientes para crear una suficiencia agroalimentaria sostenible a largo plazo. Este estudio, en base a información secundaria, analiza la situación actual de la producción agropecuaria en la provincia de Santa Elena con el fin de inferir sobre la suficiencia agroalimentaria de su población y los retos que enfrenta la provincia para lograr una soberanía alimentaria que tienda las bases de su desarrollo.
Abstract
The development of a country is mainly based on the welfare of its people through a fair redistribution of the income, a higher productivity, and the increase of work opportunities; as such the agricultural sector plays a key role for the economy and nutrition of the people. However, public policies have usually aimed at other sectors such as industry, commerce, and mining. Moreover, poor investments in scientific research, training and transfer of technology and resources contribute to low productivity and limited use of the products offered by agriculture, putting at risk the food sovereignty of the country, a key strategic objective recognized by the Constitution. This situation is even more critical to the provincial level, where provinces, such as Santa Elena, do not have enough and adequate resources to be agri-food self-sufficient and sustainable in the long run. The present study, based on secondary information, analyzes the current situation of agricultural production in the Province of Santa Elena in order to infer about the food sufficiency of its people and the challenges ahead for this province in its quest to reach food sovereignty and a steady development.

Published: July 2017

La provincia de Santa Elena es reconocida como productora de ganado caprino, ya sea por los sistemas de producción existentes, así como también por el plato típico que de ésta se oferta; la inexistencia de estudios que describan los sistemas de producción caprinos existentes en Santa Elena, ha sido el principal motivo de este estudio; que consistió en el levantamiento de información primaria aplicando encuestas a ganaderos de todas las comunas de la provincia; que fueron análizada mediante estadística descriptiva, donde se encuesto un total de 497 ganaderos, los cuales contaban con un total de 7293 animales, siendo el 75 % animales hembras, lo que demuestra una buena relación de la composición del hato, que además, está conformado con un 92 % de cabras criollas. Las variables analizadas estan relacionadas con la producción actual de caprinos y fueron agrupadas en varios componentes que son, componente social, composición del hato, tecnología existente, características de la alimentación, sanidad animal y comercialización.
Abstract
The province of Santa Elena is recognized as a producer of goats, either by the existing production systems, as well as by the typical dish that is offered; the lack of studies describing goat production systems in Santa Elena has been the main reason for this study; which consisted in the collection of primary information by applying surveys to livestock farmers of all the communes of the province; which were analyzed by descriptive statistics, where a total of 497 cattle ranchers were surveyed, which had a total of 7293 animals, 75% female animals, which shows a good relation of the composition of the herd, which, in addition, is conformed with 92% of native goats. The analyzed variables are related to the current production of goats and were grouped in several components that are, social component, herd composition, existing technology, characteristics of the feeding, animal health and commercialization.
SIMULATE-3 K coupled code applications
Authors: Jönsson C. , Grandi G. , Judd J. 
Published: July 2017

Abstract
This paper describes the coupled code system TRACE/SIMULATE-3 K/VIPRE and the application of this code system to the OECD PWR Main Steam Line Break. A short description is given for the application of the coupled system to analyze DNBR and the flexibility the system creates for the user. This includes the possibility to compare and evaluate the result with the TRACE/SIMULATE-3K (S3K) coupled code, the S3K standalone code (core calculation) as well as performing single-channel calculations with S3K and VIPRE. This is the typical separate-effect-analyses required for advanced calculations in order to develop methodologies to be used for safety analyses in general. The models and methods of the code systems are presented. The outline represents the analysis approach starting with the coupled code system, reactor and core model calculation (TRACE/S3K). This is followed by a more detailed core evaluation (S3K standalone) and finally a very detailed thermal-hydraulic investigation of the hot pin condition (VIPRE).

Authors: Borland Emma , Nägga Katarina , Nilsson Peter M. , Minthon Lennart , Nilsson Erik D. , Palmqvist Sebastian 
Published: July 2017

Background: The Montreal Cognitive Assessment (MoCA) has a high sensitivity for detecting cognitive dysfunction. Swedish normative data does not exist and international norms are often derived from populations where cognitive impairment has not been screened for and not been thoroughly assessed to exclude subjects with dementia or mild cognitive impairment. Objective: To establish norms for MoCA and develop a regression-based norm calculator based on a large, well-examined cohort. Methods: MoCA was administered on 860 randomly selected elderly people from a population-based cohort from the EPIC study. Cognitive dysfunction was screened for and further assessed at a memory clinic. After excluding cognitively impaired participants, normative data was derived from 758 people, aged 65–85. Results: MoCA cut-offs (–1 to –2 standard deviations) for cognitive impairment ranged from <25 to <21 for the lowest educated and <26 to <24 for the highest educated, depending on age group. Significant predictors for MoCA score were age, sex and level of education. Conclusion: We present detailed normative MoCA data and cut-offs according to the DSM-5 criteria for cognitive impairment based on a large population-based cohort of elderly individuals, screened and thoroughly investigated to rule out cognitive impairment. Level of education, sex, and age should be taken in account when evaluating MoCA score, which is facilitated by our online regression-based calculator that provide percentile and z-score for a subject’s MoCA score.

Background: It is known that YKL-40— a marker of glial inflammation, and VILIP-1— a marker of neuronal injury, reflect functional and structural changes in AD brains, although there is limited data concerning their potential influence on blood-brain barrier (BBB) homeostasis. Objective: Therefore, the aim of our study was to investigate the relationship between markers of inflammation and degeneration in the central nervous system (CNS) of patients with AD and mild cognitive impairment (MCI) as well as immunological response in CNS and BBB function. Methods: Cerebrospinal fluid (CSF) concentrations of proteins tested were determined in 45 AD patients, 18 MCI subjects, and 23 non-demented controls using ELISA method. Results: CSF concentrations of YKL-40 were significantly higher in MCI and AD patients, whereas CSF levels of VILIP-1 were statistically higher in the AD group as compared to the subjects without cognitive deficits. Elevated concentrations of YKL-40 correlated significantly with increased albumin quotient and decreased Aβ42/40 ratio in AD patients and with IgG quotient in the total study group. We did not find a relationship between VILIP-1 and immunological parameters reflecting BBB dysfunction and humoral immune response. Conclusion: Our findings indicate that YKL-40 may contribute to decreased stability and increased permeability of BBB in AD patients. It is assumed that YKL-40 is implicated in the development of brain barriers, although its precise mechanism of action in the BBB disruption remains unrevealed. Further studies on larger groups of patients are required to confirm our hypothesis.

Published: July 2017

Background: Reduced preoperative cognition is a risk factor for postoperative delirium. The significance for type of preoperative cognitive deficit, however, has yet to be explored and could provide important insights into mechanisms and prediction of delirium. Objective: Our goal was to determine if certain cognitive domains from the general cognitive screener, the Mini-Mental State Exam (MMSE), predict delirium after cardiac surgery. Methods: Patients completed a preoperative MMSE prior to undergoing elective cardiac surgery. Following surgery, delirium was assessed throughout ICU stay using the Confusion Assessment Method for ICU delirium and the Richmond Agitation and Sedation Scale. Results: Cardiac surgery patients who developed delirium ( n = 137) had lower total MMSE scores than patients who did not develop delirium ( n = 457). In particular, orientation to place, working memory, delayed recall, and language domain scores were lower. Of these, only the working memory and delayed recall domains predicted delirium in a regression model adjusting for history of chronic obstructive pulmonary disease, age, sex, and duration of cardiopulmonary bypass. For each word not recalled on the three-word delayed recall assessment, the odds of delirium increased by 50%. For each item missed on the working memory index, the odds of delirium increased by 36%. Of the patients who developed delirium, 47% had a primary impairment in memory, 21% in working memory, and 33% in both domains. The area under the receiver operating characteristics curve using only the working memory and delayed recall domains was 0.75, compared to 0.76 for total MMSE score. Conclusion: Delirium risk is greater for individuals with reduced MMSE scores on the delayed recall and working memory domains. Research should address why patients with memory and executive vulnerabilities are more prone to postoperative delirium than those with other cognitive limitations.
Pharmacists’ perceptions of their emerging general practice roles in UK primary care: a qualitative interview study
Authors: Butterworth Jo , Sansom Anna , Sims Laura , Healey Mark , Kingsland Ellie , Campbell John 
Published: July 2017

BackgroundUK general practice is experiencing a workload crisis. Pharmacists are the third largest healthcare profession in the UK; however, their skills are a currently underutilised and potentially highly valuable resource for primary health care. This study forms part of the evaluation of an innovative training programme for pharmacists who are interested in extended roles in primary care, advocated by a UK collaborative ‘10-point GP workforce action plan’.AimTo explore pharmacists’ perceptions of primary care roles including the potential for greater integration of their profession into general practice.Design and settingA qualitative interview study in UK primary care carried out between October 2015 and July 2016.MethodPharmacists were purposively sampled by level of experience, geographical location, and type of workplace. Two confidential semi-structured telephone interviews were conducted — one before and one after the training programme. A constant comparative, inductive approach to thematic analysis was used.ResultsSixteen participants were interviewed. The themes related to: initial expectations of the general practice role, varying by participants’ experience of primary care; the influence of the training course with respect to managing uncertainty, critical appraisal skills, and confidence for the role; and predictions for the future of this role.ConclusionThere is enthusiasm and willingness among pharmacists for new, extended roles in primary care, which could effectively relieve GP workload pressures. A definition of the role, with examples of the knowledge, skills, and attributes required, should be made available to pharmacists, primary care teams, and the public. Training should include clinical skills teaching, set in context through exposure to general practice, and delivered motivationally by primary care practitioners.

Démocratiser la science
Authors: Domènech Miquel 
Published: July 2017

Avec les sociétés de la connaissance, le rôle des savoirs experts s’est renforcé dans tous les domaines de la vie sociale. Quand ils touchent les processus délibératifs et la décision politique, leur rôle questionne la qualité et la nature des dispositifs démocratiques contemporains, compte tenu de l’éloignement de la citoyenneté qu’ils produisent dans les affaires publiques. La demande pour une démocratisation de la science a été l’une des réponses les plus fréquentes proposées à ce problème dans les études sur les sciences et technologies depuis le début du 21e siècle. Cet article suggère qu’il s’agit toujours d’un défi actuel et que cela a à voir essentiellement avec le fait qu’il a été abordé à partir de conceptions de la science et du politique qui en faisaient un objectif difficilement atteignable, voire impossible. Considérant toutefois que sa pertinence n’a pas cessé d’être avérée, l’article formule quelques suggestions quant à ce que pourraient être les questions et les thèmes à traiter pour que la démocratisation du projet scientifique devienne un projet sensé pour notre discipline.
