New process development of dense gas technology for the processing of pharmaceuticals

Sih, Roderick Peng Tze, Chemical Sciences & Engineering, Faculty of Engineering, UNSW January 2008 (has links)
Drug re-engineering is an effective method for engineering existing products in alternative dosage forms and with enhanced pharmacokinetics. Insulin for the management of diabetic symptoms is an ideal candidate for re-engineering. Current subcutaneous therapy results in low patient compliance and is ineffective in meeting the physiological need for post-prandial insulin. Implementation of dose titration for more efficient blood-glucose management is also inconvenient and uncomfortable. Inhaled insulin is presented as a superior alternative to current therapy. The lungs offer excellent access to the circulatory system. Aerosols suspended in inspired air may deposit on lung epithelia and be available for systemic absorption. To evade the defense mechanism of the human respiratory tract, particle sizes have traditionally been minimized to achieve necessary aerosol performance. Recent developments indicate that more efficient performance augmentation may also be achieved by decreasing the bulk density of powders and modifying surface characteristics. Light and fluffy powders with rough surfaces experience much higher drag forces within an airstream. The Atomized Rapid Injection for Solvent Extraction (ARISE) process is a unique precipitation platform devised by incorporating a rapid injection technique for energetic solution delivery into supercritical fluid (SCF) media to effect recovery of previously dissolved pharmaceutical compounds. The quasi-instantaneous delivery of solutions alleviates the drawbacks of the use of capillary nozzles or micro-orifices, gradual elution and mixing controlled precipitation kinetics in existing SCF precipitation techniques. Most importantly, the energetic release of solution into SCF media effects supersaturation over a much larger spatial volume and promotes the homogeneous precipitation of low bulk density powders. ARISE processed insulin powders displayed characteristics that were highly influenced by anti-solvent conditions and powders of different qualities were obtained as a function of anti-solvent pressures. At lower anti-solvent pressures, powders of narrow particle size distribution were achieved, an indication of homogeneous supersaturation levels within processing. Span, the index of size distribution was as low as 0.991. At higher anti-solvent pressures, supersaturation rates were increased while mixing efficiencies decreased, resulting in powders of wider size distribution, and powder bulk densities as low as 0.01 g/ml. Low bulk density insulin displayed in-vitro respirable fractions as high as 78%.

Master of Music / Department of Music / Reginald Pittman / This Master’s Report contains extended program notes on the works performed on a graduate rectial of music for a Baritone. The text includes biographical information on each composer and an analysis of each piece performed. Text translations are included in the body of the discussions. The pieces discussed are Handel’s “See The Raging Flames Arise,” from Joshua, Poulenc’s Le Bestiaire, Strauss’s Zueignung, Nichts and Cäcilie, Puccini’s “Questo amor, vergogna mia,” from Edgar, Jason Robert Brown’s Moving Too Fast, The Next Ten Minutes, The River Won’t Flow and She Cries and lastly Jonathon Reid Gealt’s September of ’92. The graduate recital was given in partial fulfillment of the requirements for the Master of Music degree in vocal performance on April 7, 2014. It was performed in All Faiths Chapel at Kansas State University. It featured the piano talents of Amanda Arrington, Paul Meissbach and Norma Roozeboom, the vocal talents of Reginald Pittman, Elise Poehling and Patricia Thompson, and the insrumental talents of Nolan Groff and Craig Archer.

Občanskoprávní odpovědnost při poskytování zdravotních služeb / Civil-law liability arises upon the provision of health services

Zykánová, Lenka January 2019 (has links)
1 Civil-law liability arises upon the provision of health services Abstract This diploma thesis aims to analyze in detail the civil-law liability arising out of the provision of health services; special focus is drawn to non-pecuniary damage to health and life of the patient and non-pecuniary damage of the close persons during the provision of health services by the breach of duties of the doctor, including ways and extent of compensation sustained harm. The thesis explains the current legal framework within which civil-law liability for the provision of health sevices is assessed, with individual references to the previous legal acts (i.e. the 1964 Civil Code and the Decree on compensation of non-pecuniary damage). The changes and weaknesses of the current legal framework are pointed out. The thesis comprises of an introduction, five main chapters and a conclusion. First and second chapters delimitate the issue at hand, introduce elementary terms important for the field [of civil-law liability for the provision of health services], and sources of law and shed light onto the relationship between the two key legal acts governing the provision of health services, that being the Civil Code and the Act on Provision of Helath Services. The substance of human life and health as two individual personal rights is...

Reakce společnosti na kriminální činnost mladistvých / Society Response on Juvenile Criminal

TESAŘOVÁ, Martina January 2007 (has links)
Criminal behaviour among youths is spread so widely, that almost every youth has committed one criminal aktivity at least. The top of the criminal activities of youth committers came in the half nineties. Since that time, there have been noticed new trends in youth{\crq}s criminality development. The average age of committers decreases, the brutality of crime increases and there came out new kinds of crime (children prostitution, drug criminality). In the last time it is more often discussed lowering the age limit of penal responsibility. It would be since 14 years. A new penal legislative could be authorized at the break of this and next year. This diploma work aims to chart the society{\crq}s attitude towards criminal activity of youths in chosen areas of south bohemian region. Individual points of this work are orientated towards the attitudes to the age limit of penal responsibility, to the current legislative reform in punishable activities of youths; to risky factors which cause arise of criminal behaviour. The first hypothesis was set up on the thought, that the risky factor which has an effect on arising the criminal behaviour of youths is preferred by the public in consistence in parents bringing up to school setting. Hypothesis I. was confirmed. Hypothesis one claimed that the laic public is not partisan of setting op cameras at schools. This hypothesis was disapproved. Hypothesis II. assumed that positive laic public{\crq}s attitude are for lowering the age limit of penal responsibility. This hypothesis was confirmed. Before the research, there had come out a hypothesis III. which assumes professionals positive attitude towards lowering the age limit of penal responsibility. There was pursued a research with some professionals work in a field of penal affairs of youths. There was made a half standardized interview. In the second part was done a quatitative research. That research was realized on the selective set which had 210 respondents. Some inhabitants of České Budějovice and Český Krumlov regions took part in this research. The main implement used in this research was a semantic diferencial. This diploma work should help to spread awareness and knowledge of the crime problematic of youths. Next usage could be used by professionals who are interestend in attitudes towards this problematic.

Correlación entre conocimientos sobre consecuencias de la obesidad y grado de actividad física en universitarios

Ocampo Mascaró, Javier, Silva Salazar, Vera Jimena, da Costa Bullón, Abilio 03 February 2015 (has links)
Introducción. El objetivo del presente estudio es determinar si existe correlación entre los conocimientos sobre las consecuencias de la obesidad y el grado de actividad física de las personas. Métodos. Se realizó un estudio transversal analítico durante los años 2013 y 2014. Participaron 215 alumnos de pregrado seleccionados por conveniencia no relacionados a carreras del campo de la salud en una universidad de Lima, Perú. Se evaluó el grado de actividad física utilizando el International Physical Activity Questionnaire (IPAQ) y el nivel de conocimientos sobre consecuencias de la obesidad utilizando la escala Obesity Risk Knowledge-10 (ORK-10). También, se consignó las fuentes de información de donde obtuvieron el conocimiento para responder dicho cuestionario. Resultados. La mediana de edad fue 20 (rango intercuartílico=4) y 63% eran mujeres. De acuerdo al IPAQ, 53,9% realizaban actividad física alta, 35,4%, moderada y 10,7%, leve. Se encontró una correlación muy baja (rs=0,06) entre el puntaje del ORK-10 y la cantidad de equivalentes metabólicos/minuto consumidos por semana, pero no era significativa (p=0,38). Las personas informadas por medios de comunicación y por personal de salud obtuvieron mayores puntajes en el ORK- 10 que quienes se informaron por otras vías (p<0,05). Conclusiones. La correlación entre los conocimientos sobre consecuencias de la obesidad y el grado de actividad física es muy baja. Es necesario utilizar enfoques multidisciplinarios que incluyan todos los determinantes de la realización de actividad física para poder lograr cambios en la conducta de la población.
