INORGANIC MICRO ANALYSISDuncan, Arthur January 1935 (has links)
It has always been the desire to get away
from the use of hydrogen sulphide (H2S) in the laboratory.
In the macro system Brockman (16) developed a method which
dispensed with its use. In the June issue of Journal of
Chemical Education for 1934 there appeared a system developed
by Gerstenzang (17) which dispensed with the use of HaS in
micro analysis. With the idea that the system might prove useful
here in the University, I undertook a semi-quantitative
investigation of it, under the direction of Professor W.0.
Walker, to determine the sensitivity of the tests.
Solutions of the cations were made up in 500 c.c.
bottles so that each c.c. contained 20 mg. of the cation.
Smaller dropping bottles were provided so that 1 mg. quantities
were easily available. Test reagents were made up according
to Treadwell-Hall (19) as specified in the instructions.
In all procedures the instructions were followed closely
in the first attempts. If difficulties were found in
procedure, quantities were varied in an attempt to clear
up or overcome the difficulty. / Thesis / Master of Arts (MA)

A study on factors affecting nursing turnover in Taiwan ¡V trend analysis from 1999 to 2005Chiang, Ching-Yi 22 August 2006 (has links)
The purpose of this thesis is to study the current status and past trend of nursing turnover in Taiwan. The factors affecting nursing turnover are investigated.
The research adopts longitudinal methodology and is based on the Medical Staff Database of the Department of Health, from which 420,183 samples between 1999 and 2005 are analyzed. The study results show that:
1. The registered nurses are more than non-registered ones. The average age and seniority of the nursing turnover personnel are 26 and 4.73, respectively. In hospitals, nursing turnover is higher in regional and district hospitals. In non-hospitals, the percentage of nursing turnover in home health care and nursing home is higher and increasing year by year.
2. The nursing turnover rate is closely related with economic growth rate. That is, the more the economic growth, the higher the nursing turnover.
3. With reference point in 1999, the growth rate of nursing turnover is negative from 2000 to 2001 and positive from 2002 to 2005, though a drop of 8.67% happened in 2005 when compared with 2004. Besides, the growth rate of nursing turnover in hospitals is inversely proportional to that in non-hospitals.
4. The policy of Global Budget Payment System has noticeable impact on nursing turnover. The phenomenon is most significant in clinics of the hospital organizations and home health care, nursing home and nursing school of the non-hospital organizations.

Negotiating story entry : a micro-analytic study of storytelling projection in English and JapaneseYasui, Eiko 22 June 2011 (has links)
This dissertation offers a micro-analytic study of the use of language and body during storytelling in American English and Japanese conversations. Specifically, I focus on its beginning and explore how a story is projected. A beginning of an action or activity is where an incipient speaker negotiates the floor with co-participants; they pre-indicate their intention to speak while informing the recipients of how they are expected to listen to the following talk. In particular, storytelling involves a specific need to secure long turn space before it begins since unlike other types of talk, a story usually requires more than an utterance to complete. Drawing on conversation analysis, I investigate how various communicative resources, including language, gesture, gaze, and body posture, manage such negotiation of the floor during entry into a story.
This study involves two focuses. First, it examines not only vocal means, but also non-vocal devices. Thus, I explore the linguistic resources employed to project the relationship between a forthcoming telling and ongoing talk. Specifically, I investigate how coherence and disjunction are projected differently – some stories are continuous with prior talk while others may start as a new activity. I also investigate the vocal resources for projection of a return to an abandoned story. Specifically, I demonstrate how a continuation and resumption are projected differently. Finally, I investigate the employment of non-vocal devices relevant to the projection of story entry.
Secondly, this study takes a cross-linguistic perspective. By examining conversations in two typologically different languages, American English and Japanese, I investigate how linguistic resources are consequential to the way projection is accomplished. Also, since only few studies have been conducted on storytelling in Japanese conversation, I aim to contribute to a better understanding of how the previous findings from English storytelling can be applied to Japanese conversations.
Storytelling is an important activity for human social life; telling of what we did, saw, heard about, or know helps us build good relationships with our interactants. This dissertation thus aims to explore how interactants co-construct a site for an important interpersonal activity in everyday interaction. / text

Nuovi approcci per la valutazione dell'effetto dei fungicidi nei confronti dell'oidio della vite / NEW APPROACHES FOR THE EVALUATION OF FUNGIDES' EFFECT ON GRAPEVINE POWDWRY MILDEW / New approaches for the evaluation of fungicides’ effect on grapevine powdery mildewRUSSO, GIUSEPPE 17 March 2016 (has links)
In questo lavoro si intende indagare l'effetto degli anti-oidici più diffusi al fine di individuare nuovi approcci per la ricerca sui fungicidi. Le analisi statistiche mostrano che meptildinocap, zolfo, metrafenone e penconazolo, somministrati a dosi di etichetta, prevengono le infezioni di Erysiphe necator qualora applicati fino a 12 giorni prima dell'inoculazione. Meptildinocap e zolfo conservano una buona efficacia anche se applicati fino a 9 e 6 giorni dopo l'inoculazione. Meptildinocap neutralizza il massimo numero di conidi entro 6 giorni dal trattamento. La meta-analisi multivariata eseguita su prove di campo dimostra che tutti i fungicidi riducono la gravità delle infezioni su grappolo oltre l'80%, qualora applicati da 3 a 13 volte a dosi di etichette secondo il criterio fenologico. Nonostante cyflufenamid, quinoxyfen, fenarimol, fenarimol+zolfo, propiconazolo e kresoxim-metil+boscalid siano significativamente più efficaci dello zolfo, la loro applicazione ripetuta rappresenta una condizione favorevole all’insorgenza di resistenze. L’ approccio chemio-metrico all’ analisi dei dati ottenuti da microanalisi in microscopia SEM a raggi X mostra che meptildinocap induce modificazioni nei rapporti tra Ca e Al e P e S sulla parete dei Chasmoteci trattati. Tali modificazioni sono probabilmente dovute al dissolvimento della membrana plasmatica. Questi nuovi approcci possono rappresentare un'utile integrazione ai metodi già noti. / In this work the effect of the most widespread fungicides used for Erysiphe necator management is investigated in order to test new approaches to fungicide research. ANCOVA and Tukey’s post hoc tests showed that meptyldinocap, sulfur, metrafenone and penconazole administrated at label rates prevent E. necator infections when applied up to 12 days before inoculation. Meptyldinocap and sulfur preserve a good efficacy even when applied until 9 and 6 days after inoculation. Meptyldinocap significantly increases E. necator conidia mortality within 6 days exposure. The multi-treatment meta-analysis performed on field trials shows that all fungicides reduce disease severity over 80% on vine bunches when applied from 3 to 13 times at label rates with the phenological criterion. Although cyflufenamid, quinoxyfen, fenarimol, fenarimol+sulfur, propiconazole and kresoxim-methyl+boscalid are significantly more effective than sulfur their repeated application in vineyard represents an important E. necator resistance risk. The application of chemo-metric approach to data earned by SEM X-ray microanalysis shows that meptyldinocap leads to modifications in the relationships between Ca and Al and P and S in treated Chasmothecia wall. Such modifications are probably due to the plasma membrane disruption. The new approaches tested here may represent a useful integration of already known methods.

The effect of chromium on the evolution of dispersoids in Al-Mg-Si alloysKenyon, Michael January 2018 (has links)
Aluminium is increasingly being used in the automotive industry to reduce the weight of vehicles. It is the additions of transition elements such as Mn and Cr that can be picked up during recycling, that can form dispersoid particles during homogenisation. Dispersoids play a significant role in the recrystallization and texture development for wrought Al-Mg-Si alloys by inhibiting grain boundary motion. It is therefore important to understand the precipitation kinetics of such particles. The Mn+Cr dispersoid phases are currently thought to nucleate on β'-Mg1.8Si particles via an intermediate semi-coherent precipitate denoted the u-phase. In this study, Al-Mg-Si alloys with additions of Fe and varying levels of Cr were cast to study the effect of different homogenisation regimes on the dispersoid precipitation mechanisms and final characteristics. Electron Probe Micro Analysis (EPMA) was conducted to study the inhomogeneity of elements in the cast structure and through heating to the homogenisation temperature. It was found that Mg, Si and Fe segregate towards the dendrite edges during solidification while Cr segregates towards the dendrite centre. During heating, the matrix composition of both Mg and Si decrease and increase due to precipitation of Mg+Si phases. Cr and Fe stay segregated during the heating process due to the slower diffusion rates in the face centred cubic Al matrix. Dispersoid free regions have also been observed in the microstructure correlating to the elemental segregation in the as-cast condition. Optical, scanning and transmission electron microscopy was utilised in order to study the change in dispersoid characteristics with varying homogenisation regimes and as a function of distance through a grain. With an increase in homogenisation temperature, the mean size of dispersoids increased but number density decreased. For a longer dwell time, the dispersoids remained approximately the same size but increased in volume fraction and density. Increasing the heating rate did not significantly change the dispersoid size, volume fraction or density. The dispersoids size and number density was also studied as a function of distance through a number of grains with the interplay of nucleation, growth and coarsening discussed. Both α-Al(FeCr)Si and α'-AlCrSi dispersoids were found to exist with a variety of morphologies while the α'-AlCrSi dispersoids were found to have a larger effective diameter.

A multifocal analysis of Korean educational policies on the teaching professionKim, Kyu Tae 17 June 2011 (has links)
Korean education policies were derived from the 5.31 Education Reform oriented
to the increase of autonomy and accountability for school effectiveness and the quality
instruction through teacher professionalism enhancement. The policies are related to the
influences of historical events and contexts embedded in the interactions of policy players
who have their own arguments, particularly professionalism versus managerialism. The
policies have been driven by right-wing perspectives. As a result, the roles, powers,
functions, and structures of teaching profession have gradually changed. From the
structural analysts, Basil Bernstein and Michel Foucault, teaching profession has become
a system of supervision, compliance, normalization, isomorphism related to the collection
code. The dynamic, complex and multilevel policy implementation need to be analyzed
from a multifocal approach coupled with historical institutional, political, and structural
analysis. This analysis contributes to understanding the changes of teaching profession
resulted from intricate and dynamic interactions embedded in policy environments
causing or influencing policy implementation directly and indirectly. Korean educational
policy analysts, generally, tend to use one of the institutional, the political, and the
structural perspective. Most policy analyses are concerned with the political analysis focused on exploring the political interaction between policy players, presenting policy
issues and alternatives, analyzing the new institutionalism of education policy formation
and implementation process, and influencing of policies on school organization and
teachers apart from the political environment and the political interactions. In this respect,
the multifocal policy analysis will be beneficial to shed light on a multifocal analysis of
Korean educational policies. / text

Postkomunistické Maďarsko jako příležitost: od transferu modelu urbánní intervence prostřednictvím Caisse des Dépôts et Consignations k jeho opuštění. Případ čtvrti Ferencváros v Budapešti (1988-2014) / Post-communist Hungary as an opportunity: from the transfer of urban intervention models by the Caisse des Dépôts et Consignations to its abortion, the case of Ferencváros district in Budapest (1988-2014).Saïsset, Paul January 2014 (has links)
Title of the thesis Post-communist Hungary as an opportunity: from the transfer of urban intervention models by the Caisse des Dépôts et Consignations to its abortion, the case of Ferencváros district in Budapest (1988-2014). Abstract In a context of regime change this study offers to focus on the process by which the French institution, the Caisse des Dépôts et Consignations, started the diffusion of urban intervention models and then aborted it. The analysis based on networks of actors formed locally in Hungary, attempts to describe the logics of actions constituting of this transfer at different scales: local, national and transnational. Treating this subject post-festum drove the study towards an ethnographic and historic approach, focusing on the analysis of actors' discourses in order to raise different narratives of the past actions. The fall of communism is here understood as a period of uncertainty and its successive redefinitions by politicians are still structuring the actual Hungarian political and economic issues. More than a simple rupture, this period is characterized by a power struggle in the discourses for the justification of different interest groups' actions. Thus, this event is first and foremost an opportunity. In short, the study of tangible aspects of the transnational influence...
