Citrate’S Counter Ions And Ph Effect On Gold Nanoparticle Growth Kinetics, Andrew B. Closson Dec 2016

Citrate’S Counter Ions And Ph Effect On Gold Nanoparticle Growth Kinetics, Andrew B. Closson

Honors College

The effects of citrate’s counterions and pH are examined in gold nanoparticle growth kinetics. The growth of gold nanoparticles from citrate reduction is a common method used for creating particles from 10-120 nm with a well-defined size distribution. TEM observation of the seed-mediated growth shows an intermediate aggregation phase that has been shown by researchers to exist in other solution-phase nanocrystal growth. We have shown that this intermediate agglomeration phase within particle growth may be avoided with certain pairings of counterion and pH. This aggregation phase has no noticeable effects on the formation of the particles at a smaller scale …


Planning For Climate Change: The Need For Mechanistic Systems-Based Approaches To Study Climate Change Impacts On Diarrheal Diseases, Jonathan E. Mellor, Karen Levy, Julie Zimmerman, Mark Elliott, Jamie Bartram, Elizabeth Carlton, Thomas Clasen, Rebecca Dilingham, Joseph Eisenberg, Richard Guerrant, Daniele Lantagne, James Mihelcic, Kara Nelson Apr 2016

Planning For Climate Change: The Need For Mechanistic Systems-Based Approaches To Study Climate Change Impacts On Diarrheal Diseases, Jonathan E.

Increased precipitation and temperature variability as well as extreme events related to climate change are predicted to affect the availability and quality of water globally. Already heavily burdened with diarrheal diseases due to poor access to water, sanitation and hygiene facilities, communities throughout the developing world lack the adaptive capacity to sufficiently respond to the additional adversity caused by climate change. Studies suggest that diarrhea rates are positively correlated with increased temperature, and show a complex relationship with precipitation. Although climate change will likely increase rates of diarrheal diseases on average, there is a poor mechanistic understanding of the underlying …


The Impact Of Electronic Health Records On Risk Management Of Information Systems In Australian Residential Aged Care Homes, Tao Jiang, Ping Yu, David M. Hailey, Jun Ma, Jie Yang Jan 2016

The Impact Of Electronic Health Records On Risk Management Of Information Systems In Australian Residential Aged Care Homes, Tao Jiang, Ping Yu, David M. Hailey, Jun Ma, Jie Yang

Faculty of Engineering and Information Sciences - Papers: Part A

To obtain indications of the influence of electronic health records (EHR) in managing risks and meeting information system accreditation standard in Australian residential aged care (RAC) homes. The hypothesis to be tested is that the RAC homes using EHR have better performance in meeting information system standards in aged care accreditation than their counterparts only using paper records for information management. Content analysis of aged care accreditation reports from the Aged Care Standards and Accreditation Agency produced between April 2011 and December 2013. Items identified included types of information systems, compliance with accreditation standards, and indicators of failure to meet …

Implementation Of Health Technology Assessment Work In A Hospital In Kazakhstan, Lyazzat Kosherbayeva, David M. Hailey, Kural Kurakbaev, Aleksey Tsoy, Ormanbek Zhuzzhanov, Abilay Donbay, Ainur Kumar, Kamalzhan Nadyrov

Faculty of Engineering and Information Sciences - Papers: Part A

Objectives: The aim of this study was to implement health technology assessment (HA) in the First General City Hospital in Astana, Kazakhstan. Methods: We organized trainings to familiarize hospital staff with the purpose and details of HTA. An HTA committee was established, with representation from hospital physicians and managers, and criteria for prioritization of health technologies determined. Clinical departments of the hospital were asked to prepare applications for new technologies for their services. Results: The HTA committee reviewed five applications and selected a technology from one of these, on single incision laparoscopic surgery (SILS), for assessment. A short HTA report …


A Process Of Prioritizing Topics For Health Technology Assessment In Kazakhstan, Lyazzat Kosherbayeva, David M. Hailey, Kural Kurakbaev, Adlet Tabarov, Ainur Kumar, Gulnara Gutzskaya, Elena Stepkina Jan 2016

Faculty of Engineering and Information Sciences - Papers: Part A

Objectives: The aim of this study was to develop criteria for the prioritization of topics for health technology assessment (HTA) in the healthcare system of Kazakhstan. Methods: Initial proposals for criteria were suggested through consultation with Ministry of Health (MoH) policy areas. These were refined through a workshop attended by HTA department staff, persons from medical universities and research institutes, and MoH policy makers. The workshop included discussion on methods used in international HTA practice. Opinions of participants on selection of criteria from those specified in a review of prioritization processes were used to define a list for inclusion in …


Certificate-Based Encryption With Keyword Search Enabling Secure Authorization In Electronic Health Record, Clementine Gritti, Willy Susilo, Thomas Plantard Jan 2016

Certificate-Based Encryption With Keyword Search Enabling Secure Authorization In Electronic Health Record, Clementine Gritti, Willy Susilo, Thomas Plantard

Faculty of Engineering and Information Sciences - Papers: Part B

In an e-Health scenario, we study how the practitioners are authorized when they are requesting access to medical documents containing sensitive information. Consider the following scenario. A clinician wants to access and retrieve a patient's Electronic Health Record (EHR), and this means that the clinician must acquire sufficient access right to access this document. As the EHR is within a collection of many other patients, the clinician would need to specify some requirements (such as a keyword) which match the patient's record, as well as having a valid access right. The complication begins when we do not want the server …


Australia's National Health Programs: An Ontological Mapping, Arkalgud Ramaprasad, Khin Than Win, Thant Syn, Ghassan Beydoun, Linda Dawson Jan 2016

Australia's National Health Programs: An Ontological Mapping, Arkalgud Ramaprasad, Khin Than Win, Thant Syn, Ghassan Beydoun, Linda Dawson

Faculty of Engineering and Information Sciences - Papers: Part A

Australia has a large number of health program initiatives whose comprehensive assessment will help refine and redefine priorities by highlighting areas of emphasis, under-emphasis, and non-emphasis. The objectives of our research are to: (a) systematically map all the programs onto an ontological framework, and (b) systemically analyse their relative emphases at different levels of granularity. We mapped all the health program initiatives onto an ontology with five dimensions, namely: (a) Policy-scope, (b) Policy-focus, (c) Outcomes, (d) Type of care, and (e) Population served. Each dimension is expanded into a taxonomy of its constituent elements. Each combination of elements from the …

Faculty of Engineering and Information Sciences - Papers: Part B

OBJECTIVES: The aim of this study was to obtain information on methods used to measure health technology assessment (HTA) influence, decisions that were influenced, and outcomes linked to HTA. METHODS: Electronic databases were used to locate studies in which HTA influence had been demonstrated. Inclusion criteria were studies that reliably reported consideration by decision makers of HTA findings; comparative studies of technology use before and after HTA; and details of changes in policy, health outcomes, or research that could be credibly linked to an HTA. RESULTS: Fifty-one studies were selected for review. Settings were national (24), regional (12), both national …
