We have successfully used the cadmium ion with (2-thiophenyl)phenylphosphine(PS2) or Bis(3-trimethylsilyl-2-thiophenyl)phenylphosphine(SiPS2) to synthesize [(PS2)Cd(TMEDA)](2) and [(SiPS2)Cd(TMEDA)](4) that were structurally similar to [(PS2)Zn(TMEDA)](1). We also obtained a series of zinc complxes [NEt4][(PS2)Zn(SC6H5)](6), [NEt4][{[(PS2)Zn](SC6H11)[(PS2)Zn]}](7) and [NEt4][(PS2)Zn(SCH2C6H5)](8) with systematically varied thiolates. From studying of the methylation reactions of these complexeswith methyliodine or trimethylphosphate, we found that the metal center(zinc or cadmium), ligand(PS2 or SiPS2) or the net charge (neutral ornegative) can influence the reaction time, selectivity of reaction site ormechanism. The zinc complexes (6), (7), and (8) are capable of completingthe catalytic cycle of mthylation-demethylation and hence a good model for related enzyme system.

Nós estudamos a dinâmica do operador de renormalização atuando no espaço de pares (?, t), onde ? é um difeomorfismo e t ? [0, 1], interpretados como aplicações unimodais ? o qt, onde qt(x) = -2t|x|? + 2t - 1. Estabelecemos cotas complexas a priori para pares suficientemente renormalizáveis com combinatória limitada e então a utilizamos para mostrar que quando o expoente crítico ? está próximo de um número par, o operador de renormalização tem um único ponto fixo, o qual é hiperbólico e possui uma variedade estável de codimensão um que contém todos os pares infinitamente renormalizáveis / We study the dynamics of the renormalization operator acting on the space of pairs (?, t), where ? is a diffeomorphism and t ? [0, 1], interpretated as unimodal maps ? o qt, where qt(x) = -2t|x|? + 2t - 1. We prove the so called complex bounds for sufficiently renormalizable pairs with bounded combinatorics. This allows us to show that if the critical exponent ? is close to an even number then the renormalization operator has a unique fixed point. Furthermore this fixed point is hyperbolic and its codimension one stable manifold contains all infinitely renormalizable pairs

The use of bidentate ligands in organometallic chemistry is best illustrated by the successful application in homogeneous catalysis1 and bio-medical2 systems. For catalytic systems the use of bidentate phosphines have revolutionised the way in which homogeneous catalysis is viewed, with the use of functionalised organic ligands to induce favourable catalytic product formation such as the production of L-Dopa3. To this end, the investigation of tropolone type ligands and complexes will be discussed further in this chapter. The possible application of tropolone systems will be investigated in the context of possible catalytic and bio-medical applications. In 1945 Dewar4 predicted that 2-hydroxy-2,4,6-cycloheptatrien-one (Tropolone, Eq. 1.1.I), would show certain aromatic properties; he specifically referred to the natural products known at that time, stipitatic acid and colchicine5 as representative of this class of compounds. Thus Dewar was the first person to point to a new field in organic chemistry, which to date has not been fully explored due to the diversity of uses of tropolone and its derivatives. / Prof. A.

The work group in charge of editing the trauma disorders in the upcoming edition of the International Classification of Diseases (ICD-11) made several changes to the trauma criteria. Specifically, they simplified the criteria for posttraumatic stress disorder (PTSD) and added a new trauma disorder called complex PTSD (CPTSD). To assess the new and newly defined trauma disorders, Litvin, Kaminski and Riggs developed a self-report trauma measure called the Complex Trauma Inventory (CTI). Although the reliability and validity of the CTI has been supported, no empirically-derived cutoff scores exist. We determined the optimal CTI cutoff scores using receiver operating characteristic (ROC) analyses in a diverse sample of 82 participants who experienced trauma and were recruited from an inpatient trauma unit, student veteran organizations, and university classrooms. We used the Clinician-Administered Interview for Trauma Disorders (CAIT) to diagnose the presence of an ICD-11 trauma disorder, and we correlated the results of the CAIT with the Clinician-Administered PTSD Scale for the DSM-5 to establish the convergent validity of the CAIT, r = .945, p < .001. For the ROC analyses, the CTI was used as the index test and the CAIT was used as the criterion test. The area under the curve (AUC) analyses indicated good to excellent effect sizes, AUC = .879 to .904. We identified two sets of cutoff scores for the CTI: the first set prioritized the sensitivity of the CTI scores and ranged from .884 to .962; the second set prioritized the specificity of the CTI scores and the false-positive scores (1-specificity) ranged from .054 to .143. Our study enhanced the utility of the CTI and addressed another need in the trauma field by developing a structured clinical interview (CAIT) that can be used to diagnose the ICD-11 trauma disorders.

This thesis is an investigation into the makings of a successful youth baseball facility. Youth sports is a multi-billion dollar industry in the United States, and much of the competition follows a tournament, or "travel league" format. This is especially true in youth baseball. Despite this growing trend towards travel play, facilities that host these tournaments were designed and constructed in an age where the primary format was not tournament play, but rather a recreational structure where single games were played individually. These facilities do not meet the needs of the typical park user: players and their families. The parts of the following investigation are the Author's research, including a literature review and four case studies of facilities that are representational of a larger sample. This is followed by the identification of a list of universial challenges faced by many facilities which led to a development of a list of design criteria to correct the issue of under-performing parks, identification of a fundamental design question, and specific goals and objectives. Finally, identification of a site to be studied is introduced and analyzed, and the development of the Author's concept for a new design is reported and then analyzed. The Master Plan is then presented and discussed in detail. The master plan for the new Rockville School Park has been developed based on the list of design criteria developed by the Author, based largely on field research. A large effort was made to identify literature directly regarding the questions presented in this thesis. The literature used has been included within the references section at the end of this document. / Master of Landscape Architecture / This thesis is an investigation into the makings of a successful youth baseball facility.
