    Sociologia ed epistemologia delle frontiere disciplinari: un percorso fra Bourdieu e Passeron

    No full text
    Bourdieu and Passeron are strictly linked with the French epistemological tradition named Historical Epistemology. In this paper, the author reconstructs the application of epistemological regionalism in sociology. The concept/theory of epistemological regionalism was formulated first by Bachelard and then developed by Canguilhem. It was then employed by Bourdieu and Passeron in order to describe the characteristics of sociological rationalism. After the separation from Bourdieu, Passeron developed the notion of style of reasoning (inspired by Hacking and Crombie theories). A specific focus in the article/paper is devoted to the topic of disciplinary boundaries in social science and humanities. The aim is to give a coherent reconstruction of the epistemological and sociological assumption of Bourdieu and Passeron about the disciplinary divisions on the field of social sciences and humanities

    Capillary Drop Penetration Method to Characterize the Liquid Wetting of Powders

    No full text
    We present a method to characterize the wettability of powders, based on the penetration dynamics of a sessile drop deposited on a slightly compressed powder bed. First, we show that a direct comparison of the wetting properties of different liquids is possible without having to solve the three-dimensional liquid penetration problem, by considering the appropriate dimensionless variables. We show that the contact area between the sessile drop and the powder bed remains constant during the penetration process and demonstrate that, as a result, the evolution of the dimensionless penetration volume is given by a universal function of the dimensionless time, with no dimensionless parameters. Then, using a reference liquid that completely wets the powder it is possible to obtain an effective contact angle for a test liquid of interest, independent of other properties of the powder bed, such as permeability and characteristic pore size. We apply the proposed method to estimate the contact angle of water with different powder blends, by using silicone oil as the reference liquid. Finally, to highlight the potential of the proposed method to characterize pharmaceutical powders we consider a blend of Lactose, Acetaminophen and a small amount of lubricant (Magnesium Stearate). The proposed method adequately captures a large increase in hydrophobicity that results from exposing the blend to excessive mixing, a well known effect in pharmaceutical industry.Peer reviewe

    Toward predicting tensile strength of pharmaceutical tablets by ultrasound measurement in continuous manufacturing

    No full text
    An ultrasound measurement system was employed as a non-destructive method to evaluate its reliability in predicting the tensile strength of tablets and investigate the benefits of incorporating it in a continuous line, manufacturing solid dosage forms. Tablets containing lactose, acetaminophen, and magnesium stearate were manufactured continuously and in batches. The effect of two processing parameters, compaction force and level of shear strain were examined. Young's modulus and tensile strength of tablets were obtained by ultrasound and diametrical mechanical testing, respectively. It was found that as the blend was exposed to increasing levels of shear strain, the speed of sound in the tablets decreased and the tablets became both softer and mechanically weaker. Moreover, the results indicate that two separate tablet material properties (e.g., relative density and Young's modulus) are necessary in order to predict tensile strength. A strategy for hardness prediction is proposed that uses the existing models for Young's modulus and tensile strength of porous materials. Ultrasound testing was found to be very sensitive in differentiating tablets with similar formulation but produced under different processing conditions (e.g., different level of shear strain), thus, providing a fast, and non-destructive method for hardness prediction that could be incorporated to a continuous manufacturing process.Peer reviewe

    Labeling Theory

    No full text
    Labeling theory is a sociological and criminological approach to study deviance that focuses on the process of social construction of crime. Labeling theorists attribute a major role to the social definition of the crime, to the process of labelling and stigmatization affecting deviant behavior: by assigning the label of criminal to an offender, a process is engaged that transforms the author of a single offense – or an occasional transgression – into a chronic offender. The core of deviant processes is clearly traceable to the rules that define a given conduct as right or wrong. No behavior is deviant in itself, it becomes so as soon as it is defined as such. The labeling approach therefore calls for serious thought on the power of groups within a company to define a certain behavior as deviant

    Impact of traffic vibration on the temple of Minerva Medica, Rome: preliminary study within the Co.B.Ra. project

    The impact of long-term traffic vibration on ancient structures located in the city centre of big cities is an important issue, as it represents the main factor of fatigue, possibly causing structural damage in historic constructions. This article illustrates the preliminary results of a study on the so-called Temple of Minerva Medica in Rome, Italy, conducted within the CO.B.RA. project, which focuses on the development of advanced technologies and methods for the conservation of cultural heritage assets. The studied monument, which is part of the architectural heritage of ancient Rome, is located very close to several railway tracks just out of the Termini train station, on the north-east side, and to urban tramways, on the west side. To obtain indications on the dynamic behaviour of the structure and to map the base excitation induced by passing trains and trams, ambient vibration data were acquired by digital recorders with triaxial velocimeters positioned at several measurement points on the ground, around and inside the structure, and at different heights on the north-west façade. For evaluating the structural vulnerability, three-dimensional (3D) architectural surveys and non-destructive investigations on the material properties of the monument were conducted in order to implement a finite element model of the building to be used for structural analyses and dynamic simulations. In particular, to the purpose of obtaining a detailed 3D model, laser scanner and stereo-photogrammetric acquisitions were carried out. Photographic acquisitions were also used to identify the crack pattern and to document the current state of damage. Vibration and 3D reconstruction data were acquired both in summer and in winter, along with thermographic images, for assessing the seasonal effects on the structural behaviour. All collected data were stored into an ad hoc friendly data repository accessible through the internet by the accredited project end-users

    Tesis para obtener el grado de Magíster Scientiae en Producción Animal, de la Universidad Nacional de Mar del Plata, en septiembre de 2009El objetivo del trabajo fue conocer el efecto de diferentes niveles de grano de maíz suplementario sobre la producción y composición de leche en vacas en lactancia temprana, a similar consumo de energía digestible. La hipótesis es que el aporte creciente de energía glucogénica bajo la forma de grano de maíz permite aumentar la producción de leche y concentración de proteína, cuando el consumo total de energía es constante y en condiciones pastoriles en primavera. El experimento se realizó en la EEA INTA Balcarce de octubre a diciembre de 2007, sobre una pastura de pasto ovillo (Dactilys glomerata). Los tratamientos fueron dosis crecientes de grano de maíz quebrado (T1=2 T2=4 T3=6 y T4=8 kg maíz.vaca-1.día-1) y ofertas decrecientes de pastura (T1=30,4 T2=26,4 T3=23,7 y T4=20,1 kg MS.vaca-1.día-1), a fin de generar dietas isoenergéticas. Se utilizaron 21 vacas multíparas Holando Argentino en el primer tercio de lactancia, distribuidas aleatoriamente en 4 lotes homogéneos en producción de leche y días de lactancia. Luego de un período de covariable (día 7-17 posparto) se asignaron los tratamientos durante 5 semanas (3 de acostumbramiento y 2 de medición). El consumo total promedio fue de 16,5 kg MS-1 y 40,8 Mcal EM.vaca- 1.día-1 y no difirió entre tratamientos. El consumo estimado de energía glucogénica difirió entre tratamientos no contiguos, con una diferencia máxima de 1,81Mcal ENlactancia.vaca-1.día-1 entre T1 y T4. No hubo efecto significativo de los tratamientos en producción de leche, proteína, grasa butirosa y concentración proteica. No hubo diferencias en la ganancia de peso vivo y cambio de estado corporal entre tratamientos. Dentro del rango de energía glucogénica alcanzado (18,8 a 23,9% de la energía total), la hipótesis planteada no se cumplió, para vacas consumiendo 26 Mcal ENlactación.día-1. La disponibilidad de 4,5 Mcal de ENlactación.vaca-1.día-1 de energía glucogénica estimada para el tratamiento con menor cantidad de grano de maíz (T1) fue suficiente para asegurar la producción de 20 kg de leche.vaca-1.día-1 y una concentración proteica de 29 g.kg.The objective of the study was to measure the effect of replacing pasture with corn grain as a source of energy on milk production and composition, over a Dactilys glomerata perennial pasture in spring. It was hypothesized that milk production and milk protein content would increase with increasing amounts of glucogenic energy as corn grain at a constant level of energy intake. Treatments were increasing amounts of cracked corn grain (T1=2 T2=4 T3=6 y T4=8 kg.cow-1.day-1) and decreasing amounts on pasture on offer (T1=30,4 T2=26,4 T3=23,7 y T4=20,1 kg.cow-1.day-1) to achieve isoenergetic diets. The trial was carried out in EEA INTA Balcarce. Twenty-one multiparous Holstein cows in the first stage of lactation were randomized in four homogeneous groups by milk production and days in lactation. Treatments were assigned after a covariable period (7-17 days postpartum) and the experimental period comprised 5 weeks with the last 2 weeks of measuring. Average total intake was 16,5 Kg DM.cow-1.day-1 and 40,5 Mcal ME.cow-1.day-1 and there were no differences between treatments. Estimated glucogenic energy intake was different between non consecutive treatments and the maximum difference was 1,81 Mcal NE lactation.cow- 1.day-1 between T1 and T4. There were no differences in milk production, milk fat and protein production or protein concentration between treatments. There were no differences in live weight gains or change in body condition between treatments. The increment in the proportion of glucogenic energy from 18,8 to 23,9% of total energy did not enhance production for cows consuming 26 Mcal NE of lactation.day-1. The amount of 4,5 Mcal of NE lactation.cow-1.day-1.as glucogenic energy estimated for the treatment with less corn grain intake was enough to assure a production of 20 kg milk.day-1 with a milk protein concentration of 29 g.kg.EEA MercedesFil: Barbera, Pablo.
