Public Art Commission, Where is Heidenheim? Tina O'Connell and Neal White

Research undertaken through significant public art commission. The researchers were both artists were selected separately by Dr Penelope Curtis of Tate and then the shortlist was awarded through competition (peer reviewed by Critics and Artist in Germany) part of the Heidenheim Sculpture Biennial, Germany (€18K). The work was realised by two companies in Heidenheim. Where is Heidenheim? was based within the Heidenheim Zietung newspaper[HZ] and drew together a site of a local paper in a small town in Germany with other local International papers; Wendover Times – Utah, USA;, Limerick Leader, Ireland; Free Imphal Press, Manipur, India; Hibr, Lebanon; Namibia Times, Namibia and The Countryman, Tasmania, Australia. Each of these papers ran a story showing a sign erected onto HZ in Heidenheim, which was subsequently printed inside HZ itself – linking together sites and local voices. Project research identifying global partners was conducted through the management of a PhD research student from the BU Media School - Venkata Vermuri. The work for both artists expands the context of their research into the impact of global networks on public art, and the traditions and norms of public art being confined to single ‘geographical’ sites. This research indicates the potential for media as a common public space that can also be used.

Public Art Commission Rung by Rung, Tina O'Connell

Research based on a significant public art commissions awarded through competition (peer reviewed) – Pearse Street Clinic Public Art Commission (€20K). Research was examining issues of the relationship between sculpture, exchange and communication, health and well-being. The research used an approach to question the aspirations and dreams of those who were visiting the health centre as part of a routine of daily life. Based on the aspirational concerns of individual visitors, and secondary research of positive effects of light, the final output draws on ideas based around the language of physical signage to occupy a space concerned with visitor health and wellbeing – a Health Clinic. The output has had an impact both at the site and more broadly in the context of examining sculpture and fine art as a social catalyst - based on work of socially-engaged historical practices. The installation at Pearse Street work in Dublin in Nov 09 has received critical and local acclaim. Further commissions within the public arena have been forthcoming despite difficult local economic landscape.

Public Art Commission, 1x1 project, Tina O'Connell and Neal White

A significant development in the Washington DC arts and Humanities Commission programme, the 5x5 project represented the first publicly funded arts project of this type in the US Capital. Following an International call a panel selected 20 curators who in turn selected 5 artists. All curators programmes and research were presented and 5 curators projects selected. Research into control issues surrounding the import and export of water from Japan were used to set up a project in which public were invited to put one of one thousand small droplets of this imported water onto Cherry Blossom Trees. Many of the interactions were recorded onto the database that also included documentation of sites which have vested political or national interests in the Earthquake and Fukushima Diaichi disaster in Washington DC itself. Hundreds of participants took part in the project over one week.

Predicting peptides structure with solvation potential and rotamer library dependent of the backbone

In this work, genetic algorithms concepts along with a rotamer library dependent of backbone and implicit solvation potential are used to study the tertiary structure of peptides. We starting from known primary sequence and optimize the structure of the backbone while the side chains allowed adopting the conformations present in a rotamer library. The GA, implemented with two force fields with a growing complexity, was used predict the structure of a polyalanine and a poly-isolueucine. This paper presents good and interesting results about the study of peptides structures and about the development of computational tools to study peptides structures. (C) 2007 Elsevier B.V.

Development Of New Toolkits For Orbit Determination Codes For Precise Radio Tracking Experiments

This thesis describes the developments of new models and toolkits for the orbit determination codes to support and improve the precise radio tracking experiments of the Cassini-Huygens mission, an interplanetary mission to study the Saturn system. The core of the orbit determination process is the comparison between observed observables and computed observables. Disturbances in either the observed or computed observables degrades the orbit determination process. Chapter 2 describes a detailed study of the numerical errors in the Doppler observables computed by NASA's ODP and MONTE, and ESA's AMFIN. A mathematical model of the numerical noise was developed and successfully validated analyzing against the Doppler observables computed by the ODP and MONTE, with typical relative errors smaller than 10%. The numerical noise proved to be, in general, an important source of noise in the orbit determination process and, in some conditions, it may becomes the dominant noise source. Three different approaches to reduce the numerical noise were proposed. Chapter 3 describes the development of the multiarc library, which allows to perform a multi-arc orbit determination with MONTE. The library was developed during the analysis of the Cassini radio science gravity experiments of the Saturn's satellite Rhea. Chapter 4 presents the estimation of the Rhea's gravity field obtained from a joint multi-arc analysis of Cassini R1 and R4 fly-bys, describing in details the spacecraft dynamical model used, the data selection and calibration procedure, and the analysis method followed. In particular, the approach of estimating the full unconstrained quadrupole gravity field was followed, obtaining a solution statistically not compatible with the condition of hydrostatic equilibrium. The solution proved to be stable and reliable. The normalized moment of inertia is in the range 0.37-0.4 indicating that Rhea's may be almost homogeneous, or at least characterized by a small degree of differentiation.

Synthesis of new bioactive β-lactam compounds

New biologically active β-lactams were designed and synthesized, developing novel antibiotics and enzymatic inhibitors directed toward specific targets. Within a work directed to the synthesis of mimetics for RGD (Arg-Gly-Asp) sequence able to interact with αvβ3 and α5β1-type integrins, new activators were developed and their Structure-Activity Relationships (SAR) analysis deepened, enhancing their activity range towards the α4β1 isoform. Moreover, to synthesize novel compounds active both against bacterial infections and pulmonary conditions of cystic fibrosis patients, new β-lactam candidates were studied. Among the abundant library of β-lactams prepared, mainly with antioxidant and antibacterial double activities, it was identified a single lead to be pharmacologically tested in vivo. Its synthesis was optimized up to the gram-scale, and pretreatment method and HPLC-MS/MS analytical protocol for sub-nanomolar quantifications were developed. Furthermore, replacement of acetoxy group in 4-acetoxy-azetidinone derivatives was studied with different nucleophiles and in aqueous media. A phosphate group was introduced and the reactivity exploited using different hydroxyapatites, obtaining biomaterials with multiple biological activities. Following the same kind of reactivity, a small series of molecules with a β-lactam and retinoic hybrid structure was synthesized as epigenetic regulators. Interacting with HDACs, two compounds were respectively identified as an inhibitor of cell proliferation and a differentiating agent on steam cells. Additionally, in collaboration with Professor L. De Cola at ISIS, University of Strasbourg, some new photochemically active β-lactam Pt (II) complexes were designed and synthesized to be used as bioprobes or theranostics. Finally, it was set up and optimized the preparation of new chiral proline-derived α-aminonitriles through an enantioselective Strecker reaction, and it was developed a chemo-enzymatic oxidative method for converting alcohols to aldehydes or acid in a selective manner, and amines to relative aldehydes, amides or imines. Moreover, enzymes and other green chemistry methodologies were used to prepare Active Pharmaceutical Ingredients (APIs).

Bioanalysis of new designer drugs

Since the late 1990s the illicit drug market has undergone considerable change: along with the traditional drugs of abuse that still dominate, more than 100 psychotropic substances designed to bypass controlled substances legislation have appeared and led to intoxications and fatalities. Starting from the huge class of phenylalkylamines, containing many subgroups, the spectrum of structures has grown from tryptamines, piperazines, phenylcyclohexyl derivates and pyrrolidinophenones to synthetic cannabinoids and the first synthetic cocaine. Due to the small prevalence and high number of unknown substances, the detection of new designer drugs is a challenge for clinical and forensic toxicologists. Standard screening procedures might fail because a recently discovered or yet unknown substance has not been incorporated in the library used. Nevertheless, many metabolism studies, case reports, screening methods and substance-profiling papers concentrating on single compounds have been published. This review provides an overview of the developed bioanalytical and analytical methods, the matrices used, sample-preparation procedures, concentration of analytes in case of intoxication and also gives a résumé of immunoassay experiences. Additionally, six screening methods for biological matrices with a larger spectrum of analytes are described in more detail.

Fluorescent Chrysotile From Sterling Hill, New Jersey

Minerals of the serpentine group, notably chrysotile and to a lesser extent lizardite, are widely present at both Franklin and Sterling Hill. They are late-stage hydrous magnesium silicate minerals that formed by hydrothermal alteration of earlier species, among them willemite and tephroite, and are also common components of hydrothermal veins cutting the ore bodies and the enclosing marble (Dunn, 1995). Although long recognized in the area (Fowler, 1825), local serpentine was not documented as a fluorescent mineral until 2004, when a brief description of a fluorescent serpentine from Franklin appeared in The Picking Table (Cianciulli, 2004). In the present paper, we describe additional examples of fluorescent serpentine, most from Sterling Hill.
