Las repercusiones de la crisis triguera de 1629-1631 sobre las finanzas de la ciudad de Valencia

2005

La incidencia de la crisis triguera de 1629-1631 obligó a la ciudad de Valencia a desarrollar diversos sistemas de avituallamiento. Pero ello no pudo impedir que se produjera un excepcional aumento de los precios del cereal, frente al cual el Municipio desarrolló una arriesgada política que abocó en la falta de numerario de la Taula de Canvis. La búsqueda de soluciones ante el déficit se tradujo en la elaboración, desde diferentes instancias políticas, de numerosos memoriales proponiendo múltiples y variados arbitrios frente a la crisis, cuyo análisis constituye el objetivo primordial de este artículo. The effect of the wheat crisis of 1629-1631 forced the city of Valencia to develop variou…

Darba vides risku samazināšana vairāku Rīgas loģistikas uzņēmumu darbiniekiem

2017

Kvalifikācijas darba tēma ir “Darba vides risku samazināšana vairāku Rīgas Loģistikas uzņēmumu darbiniekiem”. Darba autors ir Edrags Rutko, darba vadītājs ir Dr. biol. Juris Porozovs. Tēmas aktualitāte ir saistīta ar nepieciešamību uzlabot loģistikas uzņēmumu darba vidi atbilstoši ergonomiskajām vajadzībām, kas dod iespējas samazināt darba vides risku faktoru ietekmi uz darbinieku veselību un arodslimību attīstību. Jebkurā uzņēmumā ir iespējams uzlabot darba vidi atbilstošu darba drošības noteikumiem un ergonomikai, bet tam ir nepieciešami materiālie resursi. Darba mērķis: noskaidrot darba vides riskus un iespējas uzlabot darba vides apstākļus Rīgas loģistikas uzņēmumos. Darba uzdevumi: 1.N…

2020

Maģistra darba, kura tematika ir darba vidē balstīta profesionālā izglītība un tās īstenošanas process, autors Izglītības vadības maģistrs Viktors Kaugija. Maģistra darba būtība un mērķis ir izprast reālo situāciju praksē, kas saistās ar profesionālo izglītību darba vidē balstītos apstākļos, definēt un analizēt iespējamās problēmas darba vidē balstītās mācībās un balstoties uz iespējamo problēmu kopumu, sniegt rekomendācijas darba vidē balstītu mācību efektivitātes paaugstināšanai. Teorētiskās informācijas avotu izpētē tika izmatoti dažādi literatūras un citu informācijas avotu resursi. Teorētisko avotu izpēte daļēji pierāda reālo situāciju šīs nozares/jomas atzarā, taču savā starpā korelēj…

Afrontamiento de la muerte en familiares de pacientes ingresados en una unidad de cuidados intensivos: Valoración diferencial en función de variables…

2011

Objective to analyze the main factors that could help to face one's own death from relatives of ICU patients perspective, taking into account the influence of sociodemographic variables (gender, age, marital status and educational level). Material and method a descriptive study was carried out with family members of patients admitted to the ICU in the General Hospital (Castellón, Spain) (October 2008- December 2009). From 53 initial interviews, 26% of subjects were excluded of the study, so the total sample was made up of 39 relatives who voluntarily answered the Helping to Die in Peace Questionnaire. Results the most relevant factors that could help relatives at the time of death would be …

Facial geometry and speech analysis for depression detection.

2017

Depression is one of the most prevalent mental disorders, burdening many people world-wide. A system with the potential of serving as a decision support system is proposed, based on novel features extracted from facial expression geometry and speech, by interpreting non-verbal manifestations of depression. The proposed system has been tested both in gender independent and gender based modes, and with different fusion methods. The algorithms were evaluated for several combinations of parameters and classification schemes, on the dataset provided by the Audio/Visual Emotion Challenge of 2013 and 2014. The proposed framework achieved a precision of 94.8% for detecting persons achieving high sc…

Feature extraction for classification in knowledge discovery systems

2003

Dimensionality reduction is a very important step in the data mining process. In this paper, we consider feature extraction for classification tasks as a technique to overcome problems occurring because of "the curse of dimensionality". We consider three different eigenvector-based feature extraction approaches for classification. The summary of obtained results concerning the accuracy of classification schemes is presented and the issue of search for the most appropriate feature extraction method for a given data set is considered. A decision support system to aid in the integration of the feature extraction and classification processes is proposed. The goals and requirements set for the d…

Comparative study of reflectance cells for PLS-FTIR determination of sugars in soft drinks

1998

A comparative study has been carried out between a horizontal Attenuated Total Reflectance (h-ATR) cell and a Cylindrical Internal Reflection (CIR) cell (CIRCLE cell). Both cells were employed for the determination of glucose, fructose, sucrose and total sugar in soft drinks and fruit juices using absorbance measurements at two resolution values (4 and 8 cm–1). Data were processed by Partial Least Squares regression (PLS). Using a resolution of 4 cm–1, mean relative errors of prediction from 0.6% to 1.3% were obtained using the horizontal-ATR and from 0.6% to 2.8% using the CIRCLE cell resulting in a limit of detection from 0.03% in the case of sucrose to 0.21% for total sugar for the h-ATR…

Analyser of chromium and/or cobalt

2003

Abstract Two stopped-flow manifolds have been proposed for individual or simultaneous determination of chromium and cobalt in water samples. Automated procedures based on multicommutation systems have emphasised the differences of their catalytic effect in luminol–hydrogen peroxide chemiluminescence reaction. A more rapid decay of signal was observed for Co for both configurations (flow injection or continuous injection). The influence of chemical and hydrodynamic variables has been studied in order to establish the robustness of method. The analysis rate was lower 1.5 min per replicate. Chemometric tools have been employed for the resolution of their contributions. Partial least squares (P…
