Entre las políticas por el agua y los esfuerzos por calmar la sed. el «acueducto del desierto» en las tierras secas no irrigadas de Lavalle, Mendoza

The «aqueduct of the desert» is a necessary and iconic water works for the unirrigated area of the department of Lavalle, Mendoza. However, nearly ten years on from the beginning of its design and construction, it is disconnected from the provincial water policy and exhibits structural limitations which impede the solving of problems such as water disputes between unirrigated oasis-lands, water scarcity, and historical reparation to environmental injustice.El «acueducto del desierto» se presenta comouna obra hídrica necesaria y em-blemática para la zona no irrigada del departamento de Lavalle, Mendoza. Sin embargo, a casi diez años del inicio de su diseño y construcción, se encuentra desarticulada de la política hídrica pro-vincial y exhibe limitaciones para resolver problemas estructurales como las disputas por el agua entre oasis-tierras no irrigadas, la escasez hídrica y la reparación histórica a la injusticia ambiental del lugar.Fil: Grosso Cepparo, Maria Virginia.

Statistics of single and multiple floaters in experiments of surface wave turbulence

We present laboratory experiments of surface wave turbulence excited by paddles in the deep water regime. The free surface is seeded with buoyant particles that are advected and dispersed by the flow. Positions and velocities of the floaters are measured using particle tracking velocimetry. We study the statistics of velocity and acceleration of the particles, mean vertical displacements, single-particle horizontal dispersion, and the phenomenon of preferential concentration. Using a simple model together with the experimental data, we show that the time evolution of the particles has three characteristic processes that dominate the dynamics at different times: drag by surface waves at early times, trapping by short-lived horizontal eddies at intermediate times, and advection by a large-scale mean circulation at late times.Fil: del Grosso, Nicolas Francisco.

Propuesta de un sistema de control para mejorar la gestión de inventarios en la empresa Representaciones Alvis EIRL de Chiclayo, 2007

Uno de los principales objetivos que tienen las empresas es de mantener un determinado valor y posición en el mercado, pero la desorganización, la falta de estandarización de los procesos y descoordinación, provoca pérdidas de diferente índole y magnitud en el tiempo de cada ciclo, como en el servicio, control y costo. En esta situación se encuentra la empresa Representaciones ALVIS EIRL, por lo cual hemos creído conveniente analizar sus procesos para luego implementar un sistema de control interno de los inventarios, mediante la aplicación de un sistema de control que le permita aproximarse a estándares de calidad de control, con la finalidad de obtener un control total de los inventarios, conocer su valor comercial, el valor del producto, conocer el valor de la empresa para determinar el éxito global. En el presente estudio se hace una revisión de la situación actual de la empresa elaborando un cuestionario de preguntas para ser aplicados al personal que labora en el área de almacén en la empresa, así como al gerente, para posteriormente analizarla y tabularla, que permitirá identificar las deficiencias en el control de los inventarios; y proponer un sistema de control interno de los inventarios que traerá beneficios en cuanto al ahorro de tiempo, trabajo y dinero; así como evitar al pérdida de mercadería en almacén o el mal uso de éste. El propósito de controlar la mercadería es para detectar problemas potenciales que implica la falta de control de los inventarios; tener un exceso de inventarios, insuficiencia de inventarios, evitar los robos, las mermas, desorden que puedan impactar en las utilidades de la empresa.Tesi

Proximate composition and seed lipid components of kabuli-type chickpea (Cicer arietinum L.) from Argentina

Chickpea is an important pulse crop with a wide range of potential nutritional benefits because of its chemical composition. The purpose of the current work was to provide the chemical composition of “kabuli”-type chickpea (Cicer arietinum L.) developed in Argentina for nutritional purpose. Protein, oil and ash contents, fatty acid, tocopherol and mineral element compositions were studied. Among the studied genotypes, protein content ranged from 18.46 to 24.46 g/100g, oil content ranged from 5.68 to 9.01 g/100g and ash from 3.55 to 4.46 g/100g. Linoleic, oleic and palmitic acids were the most abundant fatty acids. The average oleic-to-linoleic ratio was 0.62 and average iodine value was 117.82. Tocopherols, well-established natural antioxidants, were found in chickpea seeds in relatively similar amounts across all genotypes. Mineral element analysis showed that chickpea was rich in macronutrients such as K, P, Mg and Ca. The nutritional composition of chickpea genotypes developed and grown in Argentina provides useful information for breeding programs, food marketing and consumers and establishes chickpea as component of a balanced human diet.publishedVersionFil: Marioli Nobile, Carla Georgina.

Two multi-fragment recombination events resulted in the beta-lactam-resistant serotype 11A-ST6521 related to Spain9V-ST156 pneumococcal clone spreading in south-western Europe, 2008 to 2016

Background: The successful pneumococcal clone Spain(9V)-ST156 (PMEN3) is usually associated with vaccine serotypes 9V and 14. Aim: Our objective was to analyse the increase of a serotype 11A variant of PMEN3 as cause of invasive pneumococcal disease (IPD) in Spain and its spread in south-western Europe. Methods: We conducted a prospective multicentre study of adult IPD in Spain (2008-16). Furthermore, a subset of 61 penicillin-resistant serotype 11A isolates from France, Italy, Portugal and Spain were subjected to whole genome sequencing (WGS) and compared with 238 genomes from the European Nucleotide Archive (ENA). Results: Although the incidence of serotype 11A in IPD was stable, a clonal shift was detected from CC62 (penicillin-susceptible) to CC156 (penicillin-resistant). By WGS, three major 11A-CC156 lineages were identified, linked to ST156 (n=5 isolates; France, Italy and Portugal), ST166 (n=4 isolates; France and Portugal) and ST838/6521 (n=52 isolates; France, Portugal and Spain). Acquisition of the capsule allowed to escape vaccine effect. AP200 (11A-ST62) was the donor for ST156 and ST838/6521 but not for ST166. In-depth analysis of ST838/6521 lineage showed two multi-fragment recombination events including four and seven fragments from an 11A-ST62 and an NT-ST344 representative, respectively. Conclusion: The increase in penicillin-resistant serotype 11A IPD in Spain was linked to the spread of a vaccine escape PMEN3 recombinant clone. Several recombination events were observed in PMEN3 acquiring an 11A capsule. The most successful 11A-PMEN3 lineage spreading in south-western Europe appeared after two multi-fragment recombination events with representatives of two major pneumococcal clones (11A-ST62 and NT-ST344)

Repositioning of the global epicentre of non-optimal cholesterol

High blood cholesterol is typically considered a feature of wealthy western countries(1,2). However, dietary and behavioural determinants of blood cholesterol are changing rapidly throughout the world(3) and countries are using lipid-lowering medications at varying rates. These changes can have distinct effects on the levels of high-density lipoprotein (HDL) cholesterol and non-HDL cholesterol, which have different effects on human health(4,5). However, the trends of HDL and non-HDL cholesterol levels over time have not been previously reported in a global analysis. Here we pooled 1,127 population-based studies that measured blood lipids in 102.6 million individuals aged 18 years and older to estimate trends from 1980 to 2018 in mean total, non-HDL and HDL cholesterol levels for 200 countries. Globally, there was little change in total or non-HDL cholesterol from 1980 to 2018. This was a net effect of increases in low- and middle-income countries, especially in east and southeast Asia, and decreases in high-income western countries, especially those in northwestern Europe, and in central and eastern Europe. As a result, countries with the highest level of non-HDL cholesterol-which is a marker of cardiovascular riskchanged from those in western Europe such as Belgium, Finland, Greenland, Iceland, Norway, Sweden, Switzerland and Malta in 1980 to those in Asia and the Pacific, such as Tokelau, Malaysia, The Philippines and Thailand. In 2017, high non-HDL cholesterol was responsible for an estimated 3.9 million (95% credible interval 3.7 million-4.2 million) worldwide deaths, half of which occurred in east, southeast and south Asia. The global repositioning of lipid-related risk, with non-optimal cholesterol shifting from a distinct feature of high-income countries in northwestern Europe, north America and Australasia to one that affects countries in east and southeast Asia and Oceania should motivate the use of population-based policies and personal interventions to improve nutrition and enhance access to treatment throughout the world.Peer reviewe

Contributions of mean and shape of blood pressure distribution to worldwide trends and variations in raised blood pressure: A pooled analysis of 1018 population-based measurement studies with 88.6 million participants

© The Author(s) 2018. Background: Change in the prevalence of raised blood pressure could be due to both shifts in the entire distribution of blood pressure (representing the combined effects of public health interventions and secular trends) and changes in its high-blood-pressure tail (representing successful clinical interventions to control blood pressure in the hypertensive population). Our aim was to quantify the contributions of these two phenomena to the worldwide trends in the prevalence of raised blood pressure. Methods: We pooled 1018 population-based studies with blood pressure measurements on 88.6 million participants from 1985 to 2016. We first calculated mean systolic blood pressure (SBP), mean diastolic blood pressure (DBP) and prevalence of raised blood pressure by sex and 10-year age group from 20-29 years to 70-79 years in each study, taking into account complex survey design and survey sample weights, where relevant. We used a linear mixed effect model to quantify the association between (probittransformed) prevalence of raised blood pressure and age-group- and sex-specific mean blood pressure. We calculated the contributions of change in mean SBP and DBP, and of change in the prevalence-mean association, to the change in prevalence of raised blood pressure. Results: In 2005-16, at the same level of population mean SBP and DBP, men and women in South Asia and in Central Asia, the Middle East and North Africa would have the highest prevalence of raised blood pressure, and men and women in the highincome Asia Pacific and high-income Western regions would have the lowest. In most region-sex-age groups where the prevalence of raised blood pressure declined, one half or more of the decline was due to the decline in mean blood pressure. Where prevalence of raised blood pressure has increased, the change was entirely driven by increasing mean blood pressure, offset partly by the change in the prevalence-mean association. Conclusions: Change in mean blood pressure is the main driver of the worldwide change in the prevalence of raised blood pressure, but change in the high-blood-pressure tail of the distribution has also contributed to the change in prevalence, especially in older age groups
