Crystallization of the altitude adapted hemoglobin of guinea pig.
2009
Hemoglobin is the versatile oxygen carrier in the blood of vertebrates and a key factor for adaptation to live in high altitudes. Several structural changes are known to account for increased oxygen affinity in hemoglobin of altitude adapted animals such as llama and barheaded goose. Guinea pigs are adapted to live in high altitudes in the Andes and consequently their hemoglobin has an increased oxygen affinity. However, the structural changes responsible for the adaptation of guinea pig hemoglobin are unknown. Here we report the crystallization of guinea pig hemoglobin in the presence of 2.6 M ammonium sulfate and a preliminary analysis of the crystals. Crystals diffract up to a resolution…
El nuevo escenario del orden público en el arbitraje : comentario a la STC de España, Sala Primera, núm. 17/2021, de 15 de febrero.
2021
The Constitutional Court delimits the concept and scope of public order, the requirement to state the grounds and the judicial review within the framework of the action for annulment of arbitral awards. The Constitutional Court rejects the jurisprudential line of the High Court of Justice of Madrid regarding the broadening of the concept of public policy and prevents the review of the merits of the case through the action for annulment.
Preliminary analysis of Palaeolithic black pigments in plaquettes from the Parpalló cave (Gandía, Spain) carried out by means of non-destructive tech…
2013
Abstract Parpallo cave (Gandia, Spain) is one of the most important Palaeolithic sites in the Spanish Mediterranean region. It is characterized by a mobiliary art whose archaeological sequence covers a dilated period (26,000–11,000 BP) and includes plaquettes decorated with black and different shades of red and yellow pigments. The aim of this paper is to present the results of analyses of the nature of black pigments used in the decoration of Parpallo plaquettes. The analyses were carried out by a non-destructive technique, by means of EDXRF. Furthermore, a colorimetric data bank has been created for conservation purposes. EDXRF measurements directly identify the use of manganese black pig…
Examining the effect of adverse weather on road transportation using weather and traffic sensors.
2018
Adverse weather related to reduced visibility caused by fog and rain can seriously affect the mobility and safety of drivers. It is meaningful to develop effective intelligent transportation system (ITS) strategies to mitigate the negative effects of these different types of adverse weather related to reduced visibility by investigating the effect of rain and fog on traffic parameters. A number of previous researches focused on analyzing the effect of adverse weather related to reduced visibility by using simulated traffic and weather data. There are few researchers that addressed the impact of adverse weather instances using real-time data. Moreover, this paper conducts comprehensive inves…
Factores que afectan al análisis biológico de las muestras de agresiones sexuales
2007
El concepto multidisciplinar de Ciencias Forenses se ha consolidado en los últimos años integrando un amplio espectro de profesionales de distintas disciplinas que ha abierto nuevas áreas de trabajo, en la mayoría de las cuales la interpretación del resultado se basa en la comparación con un material de referencia. Este trabajo pretende exponer brevemente una revisión de la casuística de Delitos Contra la Libertad Sexual (DCLS) estudiados en los laboratorios de Biología Forense y evaluar el rendimiento de la prueba de ADN a lo largo de los años en dos aspectos: uno en las situaciones inherentes a la metodología y otro en lo que respecta al cotejo de los vestigios analizados con las muestras…
A 9-level three-phase multilevel converter with harmonic mitigation and integrated battery balancing
2019
In this paper, a 9 level three-phase multilevel converter with a harmonic mitigation control method and an integrated battery balancing algorithm for automotive purpose is proposed. Each level of the converter is composed by a buck-boost converter and an h-bridge in cascaded connection. The control algorithm is implemented to achieve the harmonic mitigation on the output voltage waveform and to maintain the battery input voltages balanced. The design and operation of the system is described, and simulation study is reported using Matlab/Simulink platform.
Estudio del compostaje como técnica para la eliminación de contaminantes emergentes
2017
Desde hace unos años está surgiendo una nueva clase de contaminantes químicos utilizados por el hombre con distintas finalidades y denominados contaminantes emergentes, entre los cuales se incluyen los productos farmacéuticos. Todos estos compuestos se encuentran en las aguas residuales, y como las estaciones de depuración de aguas residuales no están acondicionadas para eliminarlos, acaban liberándose en el medio ambiente. La mayor acumulación de estos compuestos se produce en los lodos que son utilizados en agricultura y compostaje. De hecho, se han encontrado fármacos de uso humano y fungicidas de aplicación agrícola en aguas superficiales, suelos, biosólidos e incluso en agua potable. E…
Glycated albumin as a glycaemic marker in patients with advanced chronic kidney disease and anaemia: a preliminary report.
2019
BACKGROUND: The association between glycated albumin (GA) and glycaemic status has not been fully described in patients with advanced chronic kidney disease (CKD) in relation to anaemia. The aim of this study was to evaluate the relationship between GA and fasting plasma glucose (FPG) and HbA1c in patients with advanced CKD and to evaluate the influence of anaemia in such relationship. MATERIALS AND METHODS: Patients with CKD stage 4 or 5 were included in the study. eGFR was calculated by the CKD-EPI creatinine equation. Plasma GA was measured by an enzymatic method. RESULTS: Eighty-one patients were included in the study, 46 (57%) were males; the mean age was 67 ± 14 years. HbA1c was corre…
Preliminary analysis of osteocyte lacunar density in long bones of tetrapods: all measures are bigger in sauropod dinosaurs.
2013
Osteocytes harbour much potential for paleobiological studies. Synchrotron radiation and spectroscopic analyses are providing fascinating data on osteocyte density, size and orientation in fossil taxa. However, such studies may be costly and time consuming. Here we describe an uncomplicated and inexpensive method to measure osteocyte lacunar densities in bone thin sections. We report on cell lacunar densities in the long bones of various extant and extinct tetrapods, with a focus on sauropodomorph dinosaurs, and how lacunar densities can help us understand bone formation rates in the iconic sauropod dinosaurs. Ordinary least square and phylogenetic generalized least square regressions sugge…
Da “inconcludente superfetazione” a quasi contratto: la parabola ascendente del “preliminare di preliminare”
2015
Per le Sezioni Unite, “in presenza di contrattazione preliminare relativa a compravendita immobiliare che sia scandita in due fasi, con la previsione di stipula di un contratto preliminare successiva alla conclusione di un primo accordo, il giudice di merito deve preliminarmente verificare se tale accordo costituisca già esso stesso contratto preliminare valido e suscettibile di conseguire effetti ex art. 1351 e 2932 c.c., ovvero anche soltanto effetti obbligatori ma con esclusione dell’esecuzione in forma specifica in caso di inadempimento. Riterrà produttivo di effetti l’accordo denominato come preliminare con il quale i contraenti si obblighino alla successiva stipula di un altro contrat…
