The Vanishing cowboy and the unfading indian : manhood, iconized masculinity and national identity in Larry McMurtry's Lonesome dove and James Welch's Fools crow and The heartsong of Charging Elk /

Descripció del recurs: 16-03-2010Esta tesis doctoral examina la representación de la masculinidad y la identidad nacional en las novelas de Larry McMurtry Lonesome Dove y en las de James Welch Fools Crow y The Heartsong of Charging Elk. Uno de los temas de estudio principales es el encuentro con el Otro, argumentándose que esta confrontación ha posibilitado la creación de un ideal de masculinidad en el héroe del género del Western a la vez que ha facilitado la supresión de la masculinidad tradicional del indio americano. El estudio pone de manifiesto las serias consequencias que el mito del Oeste ha tenido en la masculinidad americana, consecuencias que no se ciñen al plano narrativo sino que trascienden a la vida real donde el imaginario colectivo americano continúa considerando que los mitos del Oeste forman parte esencial de la identidad masculina. El capítulo uno justifica el por qué del estudio comparativo de las obras mencionadas. Investiga además la construcción de la masculinidad hegemónica en la figura narrativa del vaquero americano, así como la conexión entre identidad nacional americana y masculinidad hegemónica. El capítulo dos analiza la presencia del Oeste histórico en la narrativa de Larry McMurtry y James Welch, evaluando la perceptión de la realidad histórica de los dos autores en su obra de no ficción antes de que éstos conviertan los hechos históricos en material para sus novelas. El capítulo tres analiza la naturaleza ambigua de los protagonistas de Lonesome Dove así como los problemas con los que se encuentra el autor a la hora de evidenciar el código masculinista del género del Western. En este capítulo también se somete a estudio el código de fraternidad masculina y la apropiación de la masculinidad del indio americano, procesos que llevan a perfilar la identidad nacional del vaquero americano. Por último, el capítulo cuatro estudia la reconceptualización de la masculinidad tradicional del indio americano en Fools Crow y The Heartsong of Charging Elk y las reflexiones del autor sobre el indio americano urbano y sobre conceptos como el indigenismo.This doctoral dissertation examines the representation of masculinity and national identity in Larry McMurtry's Lonesome Dove and James Welch's Fools Crow and The Heartsong of Charging Elk. It particularly considers the meeting with the external Other and how this confrontation has shaped the construction of certain masculinity ideals for the Western hero and erased traditional notions of masculinity for the Native American male. The study points at the devastating consequences that the myth of the West has had on American masculinity. This is not only restricted to a narrative level but transcends to the real life sphere where the collective imaginarium still regards the foundational myths of the West as constitutive part of the American male identity. Chapter one states the reasons why a comparative analysis of the novels offers a new perspective on the subject of conflicting masculinity. It also examines the construction of hegemonic masculinity in the cowboy figure as well as the connection between American national identity and hegemonic manhood. Chapter two assesses the accuracy of the historical West portrayed in Larry McMurtry and James Welch's narratives. It focuses on some of their non-fictional work to consider their perception of historical facts before they are diluted in their fictionalized world. Chapter three discusses the conflicting nature of McMurtry's cowboy protagonists in Lonesome Dove as well as the problems the author runs into when exposing the masculinist code of the Western genre. It also deals with the subject of appropriated Native American manhood and fraternal bonding as a means to shape the cowboy's national identity

Centre de vigilancia i control remot

Aquest projecte es centra en la vigilància remota. Una instal·lació de càmeres de seguretat que es permet veure via web, amb un extra de control de porter automàtic via telèfon fix. Per la realització d’aquest projecte s’ha hagut de dissenyar la infraestructura, ja sigui de cablejat com a recursos per poder presentar la visualització de les càmeres via web. La pàgina web ha sigut creada amb el llenguatge de programació PHP i HTML. En vers a aquests llenguatges de programació, abans s’ha hagut d’estudiar i obtenir els coneixements essencials per dur a terme la creació de la pàgina web. Aquest projecte neix d’una petició real, d’una proposta per la implantació d’un sistema de seguretat i control d’una casa aïllada. Per aquest motiu s’ha hagut de fer un càlcul molt acurat i real ja sigui de pressupost i d’infraestructures

Uhplc-hrms and gc-ms screening of a selection of synthetic cannabinoids and metabolites in urine of consumers

Background and Objectives: The use of synthetic cannabinoids has increased around the world. As a result, the implementation of accurate analysis in human biological matrices is relevant and fundamental. Two different analytical technologies, ultra-high-performance liquid chromatography-high-resolution mass spectrometry (UHPLC-HRMS) and high-sensitivity gas chromatography-mass spectrometry (GC-MS) were used for the determination of three synthetic cannabinoids JWH-122, JWH 210, UR-144 and their metabolites in urine of consumers. Materials and Methods: Sample preparation included an initial hydrolysis with β-glucuronidase and liquid-liquid extraction. The UHPLC-HRMS method included a Kinetex 2.6 u Biphenyl 100A (100 × 2.1 mm, 2.6 µm) (Phenomenex, Italy) column with a gradient mobile phase consisting of mobile phase A (ammonium formate 2mM in water, 0.1% formic acid) and mobile phase B (ammonium formate 2mM in methanol/acetonitrile 50:50 (v/v), 0.1% formic acid) and a full-scan data-dependent MS2 (ddMS2) mode was used (mass range 100–1000 m/z). The GC-MS method employed an ultra-Inert Intuvo GC column (HP-5MS UI, 30 m × 250 µm i.d, film thickness 0.25 µm; Agilent Technologies, Santa Clara, CA, USA) and electron-impact (EI) mass spectra were recorded in total ion monitoring mode (scan range 40–550 m/z). Results: Both methods have been successfully used for screening of parent synthetic cannabinoids and their metabolites in urine samples of consumers. Conclusions: The screening method applied JWH-122, JWH-210, UR-144 and their metabolites in urine of consumers can be applied to other compounds of the JWH family

Drug Interactions With New Synthetic Opioids

Fentanyl, fentanyl analogs, and other new synthetic opioids (NSO) have burst onto the illegal drug market as new psychoactive substances (NPS). They are often sold as heroin to unsuspecting users and produce euphoria through their agonist action on μ- opioid receptors. Their high consumption, often combined with other substances, has led to multiple intoxications during recent years. In some countries, such as the United States, the consumption of opioids, whether for medical or recreational purposes, has become epidemic and is considered a public health problem. Fentanyl analogs are more potent than fentanyl which in turn is 50 times more potent than morphine. Furthermore, some fentanyl analogs have longer duration of action and therefore interactions with other substances and medicines can be more serious. This review is focused on the potentially most frequent interactions of opioid NPS taking into account the drugs present in the reported cases of poly-intoxication, including other illegal drugs of abuse and medication. Substances involved are mainly antidepressants, antihistamines, antipsychotics, benzodiazepines, analgesics, anesthetics, psychostimulants, other opioids, alcohol, and illegal drugs of abuse. The interactions can be produced due to pharmacokinetic and pharmacodynamic mechanisms. Naloxone can be used as an antidote, although required doses might be higher than for traditional opioid intoxications. It is crucial that doctors who habitually prescribe opioids, which are often misused by patients and NPS users, be aware of designer opioids' potentially life-threatening drug-drug interactions in order to prevent new cases of intoxication
