Racemic compound versus conglomerate: concerning the crystal chemistry of the triazoylketone, 1-(4-chlorophenyl)-4,4- dimethyl-2-(1H-1,2,4-triazol-1-yl)pentan-3-one

Davey, R.J., Sadiq, G., Seaton, Colin C., Pritchard, R.G., Coquerel, G., Rougeot, C. 11 April 2014 (has links)
No / The triazoylketone discussed in this paper crystallises from racemic solutions as a conglomerate. Here, we report the ternary phase diagram confirming the conglomerate behaviour of this molecule. Through computation we also explore the underlying reasons for the absence of a racemic compound in this system and the evident epitaxial crystallisation leading to crystals of almost racemic compositions but which retain the crystal structure of the pure enantiomer. / EU-project ‘IntEnant’, Integrated Synthesis and Purification of Enantiomers

10 år med resolution 1325 i Sverige / 10 years with resolution 1325 in Sweden

Olsson, Anna January 2010 (has links)
<p>Det har gått 10 år sedan resolution 1325 om kvinnor, fred och säkerhet antogs. Den följs av olika handlingsplaner för att implementera resolutionen. Dessutom finns studier om och erfarenheter i hur man skall lyckas med implementeringen av resolution 1325. Syftet med uppsatsen är att jämföra Regeringens handlingsplan för resolution 1325 och Försvarsmaktens arbete med resolution 1325, för att lyfta fram likheter och skillnader. Syftet är även att visa vilka erfarenheter som dragits av studier om implementering av resolution 1325 och hur Regeringens plan och Försvarsmaktens arbete stämmer överens med de dragna erfarenheterna. Uppsatsen presenterar resolution 1325 och de studier som finns om resolution 1325, samt Regeringens handlingsplan för att implementera resolution 1325 och en intervju med ansvarig förimplementering av resolutionen i Försvarsmakten. Resultatet av dokumentanalysen och intervjun visar att det finns likheterna mellan Regeringens och Försvarsmaktens planer samt de studier som finns om resolution 1325, men även att det finns skillnader. Resultatet visar även vart fokus ligger i implementeringen av resolution 1325 och på vilket sätt arbetet följs upp av Regeringen och Försvarsmakten. Slutsatsen är att det finns likheter men också skillnader mellan Regeringens plan och Försvarsmaktens arbete och att båda i många fall är kopplade till tidigare studier om resolution 1325.</p> / <p>It’s been 10 years since Resolution 1325 on women, peace and security was adopted.

Enzyme- and Transition Metal-Catalyzed Asymmetric Transformations : Application of Enzymatic (D)KR in Enantioselective Synthesis

Lihammar, Richard January 2014 (has links)
Dynamic kinetic resolution (DKR) is a powerful method for obtaining compounds with high optical purity. The process relies on the combination of a kinetic resolution with an in situ racemization. In this thesis, a combination of an immobilized hydrolase and a transition metal-based racemization catalyst was employed in DKR to transform racemic alcohols and amines into enantioenriched esters and amides, respectively. In the first part the DKR of 1,2-amino alcohols with different rings sizes and N-protecting groups is described. We showed that the immobilization method used to support the lipase strongly influenced the stereoselectivity of the reaction. The second part deals with the DKR of C3-functionalized cyclic allylic alcohols affording the corresponding allylic esters in high yields and high ee’s. The protocol was also extended to include carbohydrate derivatives, leading to inversion of a hydroxyl substituted chiral center on the carbohydrate. The third part focuses on an improved method for obtaining benzylic primary amines. By using a novel, recyclable catalyst composed of Pd nanoparticles on amino-functionalized mesocellular foam, DKR could be performed at 50 °C. Moreover, Lipase PS was for the first time employed in the DKR of amines. In the fourth part DKR was applied in the total synthesis of Duloxetine, a compound used in the treatment of major depressive disorder. By performing a six-step synthesis, utilizing DKR in the enantiodetermining step, Duloxetine could be isolated in an overall yield of 37% and an ee &gt;96%. In the final part we investigated how the enantioselectivty of reactions catalyzed by Candida Antarctica lipase B for δ-substituted alkan-2-ols are influenced by water. The results showed that the enzyme displays much higher enantioselectivity in water than in anhydrous toluene. The effect was rationalized by the creation of a water mediated hydrogen bond in the active site that helps the enzyme form enantiodiscriminating binding modes. / <p>At the time of the doctoral defense, the following paper was unpublished and had a status as follows: Paper 3: Manuscript.</p>

Using multiple digital image to synthesize a high-resolution image

Zeng, Jhao-Yu 31 August 2011 (has links)
In this paper, we propose an image registration algorithm to form a set of images to a high-resolution image. This algorithm employs a fringe projected scheme to perform the registration. The proposed algorithm provides several advantages, such as high precision, low computation cost, simple system configuration and robotic performance. An example which used three images to form a hight-resolution image was given. It was found that the resolution had enhanced 2.72 times.

Establishing a Ministry of Peace in Zambia.

Lyoba, Bernard Chilufya. January 2009 (has links)
Zambia faces extensive conflict and violence of both direct and structural types. The qualitative and quantitative indices provided by the Global Peace Index (GPI), the Human Development Index (HDI) and the Gender Disparity Index (GDI) confirm that Zambia needs a control shift permeated with tools of peacefulness that will move the country from a culture of violence to a culture of peace and non-violence. The focus of the dissertation is one way of trying to build sustainable peace in the world and in particular Zambia by creating structures within government circles, specifically by establishing a Ministry of Peace that will work to transcend violent conflicts while working alongside a Peace Education Commission (PEC), Peace Research Commission (PRC) and an independent Conflict Resolution and Mediation Commission (CRMC). The aim of such a ministry is to help change the mindset of the people of Zambia from a culture of violence towards to a culture of peace and non-violence. The dissertation discusses possible objections to a Ministry of Peace and proposes a strategic plan for establishing a Ministry of Peace in Zambia. Two focus groups were selected to provide a very small sample of Zambians the opportunity to comment on the idea of establishing a Ministry of Peace in Zambia. / Thesis (M.Com.)-University of KwaZulu-Natal, 2009.

Comparison of Spatial Resolution and Contrast Uniformity of Various Printers

Madhavji, Milan 12 January 2011 (has links)
For several common inkjet, laser and thermal dye printers, a method of evaluating prints that is not associated with the level of dental expertise of the observer is introduced. In addition, an automated analysis that mimics the observations made by observers is tested. Metrics that are evaluated in this study include spatial resolution, contrast uniformity, the type of paper, and overall observer preference. The results demonstrate that observer preference is associated with a high print contrast uniformity and with the use of glossy paper, but not with increased spatial resolution. The automated analysis produced results that were in general agreement with the observer data for spatial resolution, which concluded that the Lexmark C543DN printer produced prints with the highest spatial resolution. A thermal dye printer (Kodak CMI1000) produced prints with the highest contrast uniformity, and the print most favored by observers overall was produced by the Kodak ESP-9 inkjet printer on Kodak Everyday Glossy Photo paper.

Supranational systems of dispute resolution and their integration into domestic legal systems : a view of the Latin American Experience

Aguilar, Sofia Beatriz. January 1999 (has links)
The influence of globalization over legal systems has resulted in, among other effects, the emergence of transnational law and new international players, such as multinational corporations (MNEs), non-governmental organizations (NGOs) and numerous international entities. The dynamics of the new players within the new transnational legal order have generated a need for a new supranational system of dispute resolution. / The analysis focuses on the Latin American experience in adapting to judicial reform programs (sponsored by international organizations such as the World Bank and the International Development Bank) which promote the integration of Alternative Dispute Resolution (ADR) methods into domestic legal systems, in order to integrate such systems into a supranational system of dispute resolution for the entire continent. / This study aims to explore various alternatives for preventing a continental supranational system of dispute resolution from undermining domestic democracies, while integrating developing countries into the process of commercial globalization.
