Teorías del Estado y estudios sobre gubernamentalidad: contrapuntos posibles
Authors: Campana Melisa 
Published: October 2017

• Mucho se ha debatido acerca del ajuste estructural y la reforma del Estado en América Latina, de la caída de los sistemas de Estado de Bienestar y el auge del pensamiento neoliberal, de la reorientación de las protecciones sociales hacia la focalización, descentralización y privatización, movimientos que comienzan a gestarse hacia fines de la década del ‘70 y que, en el caso de Argentina, terminan de consolidarse en los ‘90. Precisamente, con la intención de ofrecer canales de entrada a la discusión acerca del Estado y su “reforma” o “reinvención”, el presente trabajo presenta una serie de contrapuntos entre las teorías del Estado y los estudios sobre gubernamentalidad. La perspectiva analítica adoptada se basa, fundamentalmente, en el enfoque proveniente de los governmentality studies y pretende entablar un diálogo crítico entre diversas claves analíticas. Para ello, se vale de nociones caras tanto al pensamiento político como sociológico y establece contrapuntos entre: Estado y gobierno; democratización de la administración pública y gubernamentalización del gobierno; territorialización y gobierno a través de la comunidad. El objetivo de este artículo es identificar no sólo las divergencias sino también los intercambios posibles entre ambos enfoques y es por ello que la reflexión se organiza sobre la base de los mencionados contrapuntos, no como absolutos opuestos sino como heterogéneos. • With a view to offering avenues of debate on the State and its “reform” or “re-invention”, this paper presents a number of counterpoints between theories about the State and governmentality studies. The analytical approach taken is primarily based on the focus used in governmentality studies and aims to set up a critical dialogue between various standpoints. Hence, it takes account of notions held in high esteem both in political and sociological thought such as State, government, society and community. The aim of this study is to identify not only divergent aspects but also the potential exchanges between the two approaches, this being the reason why reflection revolves around various counterpoints, which are seen not as opposing but as heterogeneous absolutes.
Wear Resistance Performance of Conventional and Non-Conventional Wind Turbine Blades with TiN Nano-Coating

Published: October 2017

Efficiency and durability are critical issues that affect widely-adopted aerofoil-power generator as a sustainable source of electrical power. Even though high wind power density can be achieved; installing wind turbines in desert condition has difficulties including thermal variation, high turbulence and sand storms. Sand blasting on turbine blade surface at high velocities causes erosion resulting turbine efficiency drop. Damage-induced erosion phenomena and aeroelastic performance of the blades needed to be investigated. Suitable coating may prevent erosion to a great extent. A numerical investigation of erosion on NACA 4412 wind turbine blade has been performed using commercial computational fluid dynamics software ANSYS FLUENT 14.5 release. Discrete phase model (DPM) has been used for modelling multi-phase flow of air and sand particles over the turbine blade. Governing equations have been solved by finite volume method (FVM). Conventional 30-70% glass fibre resin and non-conventional jute fibre composite have been used as turbine blade material. Sand particles of diameter have been injected from 20, 30, 45, 60 and 90 degree angles at 500C temperature. Erosion rate, wall shear stress and strain rate have been calculated for different wind velocities and impingement angles. Simulation results for higher velocities deviate from the results observed at lower wind velocities. In simulation, erosion rate is highest for impingement angle at low wind velocities, which has been validated by experiment with a mean absolute error (MAE) of 5.56%. Erosion rate and wall shear stress are higher on jute composite fibre than glass fibre resin. Developed shear stress on wind turbine blade surface is highest for impingement angle at all velocities. On the other hand, exerted pressure on turbine blade surface is found highest for 9 angle of attack. Experimental results, with or without Titanium nitride(TiN) nano-coating, also revealed that surface roughness augments with increasing impingement angles. Nano-coating (TiN) by RF sputtering technique reduced the surface roughness significantly as oppose to uncoated samples. Highest roughness has been observed on uncoated blade surface collided with 0.3-0.69 mm diameter brown aluminium oxide particles.

Reliability of CSF turbulence and choroid plexus visualization on fast-sequence MRI in pediatric hydrocephalus
Authors: Rozzelle Curtis J. , Madura Casey , Reeder Ron W. 
Published: October 2017

OBJECTIVEEndoscopic third ventriculostomy with choroid plexus cauterization for the treatment of neonatal and infant hydrocephalus has gained popularity in the past decade. Identifying treatment failure is critically important. Results of a pilot study of 2 novel imaging markers seen on fast-sequence T2-weighted axial MRI showed potential clinical utility. However, the reliability of multiple raters detecting these markers must be established before a multicenter validation study can be performed.METHODSTwo sets of de-identified single-shot T2-weighted turbo spin-echo axial images were prepared from scans of patients before and after they underwent endoscopic third ventriculostomy with choroid plexus cauterization between March 2013 and January 2016. The first set showed the lateral and third ventricles for visualization of turbulent CSF dynamics, and the second set showed the lateral ventricular atria for choroid plexus glomus detection. Three raters (Group 1) received written instructions before evaluating each image set once and then again 1 week later. Another 8 raters (Group 2) evaluated both image sets after oral instruction and group training on a pretest image set. Fleiss’ kappa coefficients with 95% CIs were calculated for intrarater and interrater reliability in Group 1 and interrater reliability in Group 2.RESULTSIntrarater reliability kappa coefficients for Group 1 were ≥ 0.74 for turbulence and ≥ 0.80 for choroid plexus; their interrater kappa coefficients at the initial assessment were 0.50 (95% CI 0.37–0.62) and 0.56 (95% CI 0.43–0.69), respectively. The Group 2 interrater kappa scores were 0.82 (95% CI 0.78–0.86) for turbulence and 0.62 (95% CI 0.58–0.66) for choroid plexus.CONCLUSIONSWith minimal training, intrarater reliability on visualization of turbulence and the choroid plexus was substantial, but interrater reliability was only moderate. After modestly increasing training, interrater reliability improved to near perfect and to substantial reliability for visualization of turbulence and choroid plexus, respectively. Given adequately trained observers, a multicenter investigation into the validity and potential clinical utility of the imaging markers seems feasible.

Published: October 2017

The study was conducted to determine the effect of salinity stress on morphological and nutritional quality of Napier cultivars in terms of biomass yield, tiller numbers, leaf number, tiller height, shoot presence or absence per cutting, leaf condition, dry matter (DM) and crud protein (CP) content under hydroponic condition. four Napier cultivars such as BLRI Napier-1, BLRI Napier-2, BLRI Napier-3 and BLRI Napier-4 were cultivated under hydroponic system developed by Bangladesh Agricultural Research Institute (BARI) with some modifications. All the selected cultivars were grown by using BARI standard hydroponic solution. Five salinity levels were considered as treatments such as 3, 4, 5, 6 and 7 dS m-1 using different NaCl concentrations corresponding to the nutrient solution which were noted as T1 to T5 and T0 was used as control where salinity level was 2.3 dSm-1. Four Napier cultivars were grown with 4 replications under each salinity condition and all the treatments were arranged in a Randomized Complete Block (RCB) design. Shoot presence or absence per cutting and leaf condition were determined weekly. The results revealed that the biomass yield, number of tillers, leaf numbers, tiller height, shoot presence or absence per cutting, leaf condition, and DM and CP content among all the cultivars were decreased linearly with the increased of salinity levels. On the basis of different morphological and nutritional parameters, tolerance level of different cultivars of Napier grass to salinity stress can be rated as: BLRI Napier-4>BLRI Napier-3 > BLRI Napier-2 >BLRI Napier-1. Further study need to determine the suitability for large scale adaptation under on-farm conditions.Bang. J. Anim. Sci. 2017. 46 (2): 102-108
The Charlson Comorbidity Index in Registry-based Research
Authors: Lagergren Jesper , Brusselaers Nele 
Published: October 2017

SummaryBackground: Comorbidities may have an important impact on survival, and comorbidity scores are often implemented in studies assessing prognosis. The Charlson Comorbidity index is most widely used, yet several adaptations have been published, all using slightly different conversions of the International Classification of Diseases (ICD) coding.Objective: To evaluate which coding should be used to assess and quantify comorbidity for the Charlson Comorbidity Index for registry-based research, in particular if older ICD versions will be used.Methods: A systematic literature search was used to identify adaptations and modifications of the ICD-coding of the Charlson Comorbidity Index for general purpose in adults, published in English. Back-translation to ICD version 8 and version 9 was conducted by means of the ICD-code converter of Statistics Sweden.Results: In total, 16 studies were identified reporting ICD-adaptations of the Charlson Comorbidity Index. The Royal College of Surgeons in the United Kingdom combined 5 versions into an adapted and updated version which appeared appropriate for research purposes. Their ICD-10 codes were back-translated into ICD-9 and ICD-8 according to their proposed adaptations, and verified with previous versions of the Charlson Comorbidity Index.Conclusion: Many versions of the Charlson Comorbidity Index are used in parallel, so clear reporting of the version, exact ICD- coding and weighting is necessary to obtain transparency and reproducibility in research. Yet, the version of the Royal College of Surgeons is up-to-date and easy-to-use, and therefore an acceptable co-morbidity score to be used in registry-based research especially for surgical patients.
