Analytical Characterization, Thermal And Ftir Studies Of Urinary Calculi

Urolithiasis is identified to be a major urological disorder affecting people all over the world irrespective of their age, sex and race. Urinary stone samples resected from the urinary bladders of two patients belonging to tropical region, Kollam District of Kerala State, India are investigated by using XRD,SEM, EDAX, TGA, DSC and FTIR to understand its chemical structure. Uric acid shows exothermic peak around 432°C is due to the decomposition with the evolution of CO and cracking of the remaining products. Results of analytical studies reveal that samples under investigation consist mainly in uric acid and hydrated uric acid. Hydrogen bonding exists in hydrated uric acid samples

Nonpoint source pollution, space, time and asymetric information - a deposit refund approach

The incorporation of space allows the establishment of a more precise relationship between a contaminating input, a contaminating byproduct and emissions that reach the final receptor. However, the presence of asymmetric information impedes the implementation of the first-best policy. As a solution to this problem a site specific deposit refund system for the contaminating input and the contaminating byproduct are proposed. Moreover, the utilization of a successive optimization technique first over space and second over time enables definition of the optimal intertemporal site specific deposit refund system

Re-using (rescheduling) an Adobe Connect meeting for a new date, time and participants

A two-minute video that shows you how to edit an existing meeting in Adobe Connect so you can re-use that meeting room for a new date, time and (if needed) different participants.

I wonder why the sun rises : and other questions about time and seasons.

Pertenece a una colección que quiere responder a las preguntas que se hacen los jóvenes lectores sobre el tiempo y las estaciones del año. Podemos conocer las respuestas a temas como la duración del día según la época del año, la influencia de la latitud para que haya cuatro o menos estaciones; la creación del calendario, la forma de medir con exactitud el tiempo, la diferencia horaria en los distintos países del mundo.

New insights into boar sperm function and survival from integrated field and laboratory studies

En aquesta tesi s'han dut a terme dos tipus d'estudis diferents. L'objectiu del primer era la preservació del semen de porcí a 15ºC i el del segon eren els co-cultius homòlegs de cèl·lules epitelials de l'oviducte i espermatozoides de porcí. Pel que fa al primer estudi, s'ha observat que l'addició de la prostaglandina F2α i àcid hialurònic a les dosis seminals no malmena la qualitat espermàtica i que la tolerància dels espermatozoides als canvis d'osmolalitat del medi es pot correlacionar proves de fertilitat i prolificitat.. Respecte el segon, s'ha determinat que les cèl·lules oviductals afecten els paràmetres espermàtics i que la presència d'espermatozoides sobreexpressa els gens que codifiquen per les proteïnes de xoc tèrmic. Així, se suggereix que aquestes proteïnes tenen algun paper en els processos reproductius que tenen lloc a l'oviducte, malgrat que s'hagi observat, mitjançant la tècnica de la interferència de l'RNA, que la HSP90AA1 no està implicada en el perllongament de la viabilitat espermàtica.

Environmental governance from a gender perspective. Theoretical reflections and case studies

In the second half of the twentieth century we saw the environmental debate escalate into one of the most challenging and complex issues that authorities at international, national, regional and municipal levels have to deal with. The inherent complexity of environmental problems, which brings out the interconnections between the economic, socio-cultural and ecological dimensions of the territory, is increased by the social, scientific and political focuses of the debate, and their interdependencies. In the framework of governance, scientific and technical assessments are a relevant but not “unique” source for legitimating environmental policymaking. The discussion is opened towards the consideration of different existing perspectives on the environment. The main objective of the present study is to systematize and explore in-depth the perspectives brought by feminism and gender to environmental governance. What is the specificity of a feminist and gender outlook? In what sense does it bring new light to environmental governance processes? Such questions are explored empirically and theoretically.

Managanese and dicopper complexes for bioinspired oxidation reactions: catalytic and mechanistic studies on C-H and C=C oxidations

Enzymes are high-weight molecules which catalyze most of the metabolic processes in living organisms. Very often, these proteins contain one or more 1st row transition metal ions in their active center (Fe, Cu, Co, Mn, Zn, etc.), and are known as metalloenzymes or metalloproteins. Among these, metalloenzymes that activate molecular oxygen and use it as terminal oxidant stand out because of the wide range of catalyzed reactions and their exquisite selectivity. In this PhD dissertation we develop low-weight synthetic bioinspired complexes that can mimic structural and/or functional features of the active center of oxigenases. In the first part, we describe the use of unsymmetric dinuclear Cu complexes which are capable of performing the oxidation of phenols and phenolates in a analogous manner of the tyrosinase protein. In the second part, we describe the use of mononuclear manganese complexes in the oxidation of alcanes and alquenes.
