Una aproximación a la agencia policial de la provincia de Buenos Aires : las reconfiguraciones en la Policía Bonaerense desde finales de los años 90 a la actualidad

Esta ponencia presenta los primeros resultados de una indagación exploratoria, de carácter sincrónico y diacrónico, acerca del eslabón policial de la cadena punitiva. Se atiende a las incumbencias, competencias y despliegue de la policía de la provincia de Buenos Aires, dando cuenta de sus cambios/continuidades junto con la emergencia de nuevos cuerpos de "seguridad" durante las últimas dos décadas. Se analizan, en particular, las constantes declaraciones de "emergencia de seguridad" que reafirmarían el poder policial, facultando la proliferación de nuevos cuerpos y efectivos en las calles. Asimismo, habilitarían nuevas modalidades de gobierno de los espacios socio-territoriales, versando en la retórica neoliberal de la "prevención del delito" y la "protección ciudadana".Fil: Rizzon, Fernando.

Decision Problem of Instrumentation in a Company involved in ISO 50001

International audience—In the context of performance management and the involvement of companies in sustainable development, energy management is a new challenge. Managing energy is a complex problem as it can potentially impact the whole company and if mishandled could be harmful for its added value. In order to assist companies in this challenge, the ISO 50001 proposes a standard for the creation of Energy Management Systems (EnMS). Such systems bring the recurring problem of decision about the choice of the actions necessary into their deployments. Notably, they rely heavily on the data related to the consumptions of energy and its usage in a given company. Hence the problem of decision, at an audit stage, can concern the choice of a sound instrumentation. This paper deals with the interest of the company adixen Vacuum Products in a standard for decision aiding in this situation. The idea is to build the model of preference of the Decision Maker and to establish a generic procedure about decision supported by a MCDA tool. Our proposition is to use the ACUTA method in order to elicit this model of preference

Physicochemical composition, minerals, and pesticide residues in organic grape juices.

Demand for organic products is intensified in many countries each year. Following this trend, Brazil produces increasing volumes of organic grape juice. In this way, a survey of organic grape juices made from grapes produced according to this system was carried out where physicochemical composition, minerals, trace elements, and pesticide residues were determined. Variables related to grape juice composition were performed by physicochemical procedures; minerals and trace elements, by inductively plasma optical emission spectrometry; pesticide residues, by liquid chromatography-mass spectrometry. Main results show that the physicochemical composition of organic grape juices was in general in accordance to the Brazilian legislation. The mean concentrations of trace elements were very low, varying from 0.002 (Cd) to 0.970 (Ba) mg L?1. Pesticide residues were not detected in any sample analyzed (MRL= 10 μg L?1). These results show that the Serra Gaúcha viticultural region present conditions to produce organic grape juices, despite the adverse climate factors that occurs in some years. Nevertheless, these products should be made with grape varieties, such as the labrusca ones, less susceptibles to the main grapevine pathogens

Multivariate SPC for Total Inertial Tolerancing

This paper presents a joint use of the T² chart and Total Inertial Tolerancing for process control. Here, we will show an application of these approaches in the case of the machining of mechanical workpieces using a cutting tool. When a cutting tool in machining impacts different manufactured dimensions of the workpiece, there is a correlation between these parameters when the cutting tool has maladjustment due to bad settings. Thanks to Total Inertial Steering, the correlation structure is known. This paper shows how T² charts allow one to take this correlation into account when detecting the maladjustment of the cutting tool. Then the Total Inertial Steering approach allows one to calculate the value of tool offsets in order to correct this maladjustment. We will present this approach using a simple theoretical example for ease of explanation

Effects of L-carnitine administration on left ventricular remodeling after acute anterior myocardial infarction: The L-carnitine Ecocardiografia Digitalizzata Infarto Miocardico (CEDIM) trial

Objectives. This study was performed to evaluate the effects of l-carnitine administration on long-term left ventricular dilation in patients with acute anterior myocardial infarction. Background. Carnitine is a physiologic compound that performs an essential role in myocardial energy production at the mitochondrial level. Myocardial carnitine deprivation occurs during ischemia, acute myocardial infarction and cardiac failure. Experimental studies have suggested that exogenous carnitine administration during these events has a beneficial effect on function. Methods. The l-Carnitine Ecocardiografia Digitalizzata Infarto Miocardico (CEDIM) trial was a randomized, double-blind, placebo-controlled, multicenter trial in which 472 patients with a first acute myocardial infarction and high quality two-dimensional echocardiograms received either placebo (239 patients) or l-carnitine (233 patients) within 24 h of onset of chest pain. Placebo or l-carnitine was given at a dose of 9 g/day intravenously for the first 5 days and then 6 g/day orally for the next 12 months. Left ventricular volumes and ejection fraction were evaluated on admission, at discharge from hospital and at 3, 6 and 12 months after acute myocardial infarction. Results. A significant attenuation of left ventricular dilation in the first year after acute myocardial infarction was observed in patients treated with l-carnitine compared with those receiving placebo. The percent increase in both end-diastolic and endsystolic volumes from admission to 3-, 6- and 12-mouth evaluation was significantly reduced in the l-carnitine group. No significant differences were observed in left ventricular ejection fraction changes over time in the two groups. Although not designed to demonstrate differences in clinical end points, the combined incidence of death and congestive heart failure after discharge was 14 (6%) in the l-carnitine treatment group versus 23 (9.6%) in the placebo group (p = NS). Incidence of ischemic events during follow-up was similar in the two groups of patients. Conclusions. l-Carnitine treatment initiated early after acute myocardial infarction and continued for 12 months can attenuate left ventricular dilation during the first year after an acute myocardial infarction, resulting in smaller left ventricular volumes at 3, 6 and 12 months after the emergent event
