Hybrid graphite film–carbon nanotube platform for enzyme immobilization and protection

A novel platform consisting of a multilayered substrate, activated graphite-like carbon film, and dense forest of long, vertically-aligned multiwall carbon nanotubes grown by the chemical vapor deposition is designed, fabricated, and tested for covalent immobilization of enzymatic biocatalysts with the aim of protecting them from shear forces and microbial attacks present in bioreactors. The covalent bonding ensures enzyme retention in a flow, while the dense nanotube forest may serve as a protection of the enzymes from microbial attack without impeding the flow of reactants and products. This platform was demonstrated for the two reference enzymes, horseradish peroxidase and catalase, which were immobilized without degrading their biological activity. This combination of an activated carbon layer for an efficient immobilization of biocatalysts with a protective layer of inert carbon nanotubes could dramatically improve the efficiency and longevity of enzymatic bio-catalysis employed in a large variety of advanced biotechnological processes.

Planning to Learn : Creating and Using a Personal Planner with Young People on the Autism Spectrum

Late intervention often means that young people on the autism spectrum appear to act on impulse, seem disorganized, or fail to learn from past experiences. In this practical, effective resource, the authors share tried and tested techniques for creating and using a personal planner to help individuals on the autism spectrum to develop independence. "Planning to Learn" is split into three parts. The first part guides adults in helping young people to make sense of the world and to develop and practise coping strategies for any given situation. The authors also explain how simple visual and verbal cues can help people to cope successfully in stressful situations. The second part provides worksheets for the young person to complete to learn how to use plans in different situations, for example staying calm when waiting for a doctor, or coping with a change in the school timetable. Each individual makes a unique planner with procedures to refer to, such as responding to pressure, calming down, being organised, and being around people. The third part includes useful cards, schedules and plans for photocopying and including in the planner. This illustrated photocopiable workbook is packed with guidance, support and helpful notes for those new to, or experienced in, working with children and young people with ASD. It can be used within educational and community settings or at home.

Multimedia copyright protection

Internet and its widespread usage for multimedia document distribution put the copyright issue in a complete new setting. Multimedia documents, specifically those installed on a web page, are no longer passive as they typically include active applets. Copyright protection safeguards the intellectual property (IP) of multimedia documents, which are either sold or distributed free of charge. In this Chapter, the basic tools for copyright protection are discussed. First, general concepts and the vocabulary used in copyright protection of multimedia documents are discussed. Later, taxonomy of watermarking and fingerprinting techniques are studied. This part is concluded by a review of the literature dealing with IP security. The main part of the chapter discusses the generic watermarking scheme and illustrates it on three specific examples: collusion-free watermarking, spread spectrum watermarking, and software fingerprinting. Future trends and conclusions close the chapter.

A qualitative exploration of sun safety beliefs among Australian adults

Informed broadly by the theory of planned behaviour, this study used qualitative methodology to understand Australian adults' sun-protective decisions. Forty-two adults participated in focus groups where they discussed behavioural (advantages and disadvantages), normative (important referents), and control (barriers and facilitators) beliefs, as well as potential social influences and images of tanned and non-tanned people. Responses were analysed using the consensual qualitative research approach to determine the dominant themes. Themes of fashion and comfort were prominent, the important role of friends and family in sun safe decision-making was highlighted, as was the availability of sun-protective measures (e.g., in an accessible place or in the environment). Additional themes included the need to model sound sun-protective behaviours to (current and future) children, the emphasis on personal choice and personal responsibility to be sun safe, and the influence of Australian identity and culture on tanning and socially acceptable forms of sun protection. These beliefs can be used to inform interventions and public health campaigns targeting sun safety among Australians, a population with the highest skin cancer incidence in the world.

An investigation approach to test protection intelligent electronic devices (IEDs) in IEC 61850 based substation automation systems (SAS) at station level

This thesis has developed a new approach to trace virtual protection signals in Electrical substation networks. The main goal of the research was to analyse the contents of the virtual signals transferred, using third party software. In doing so, a comprehensive test was done on a distance protection relay, using non-conventional test equipment.

Jurisprudential Challenges to the Protection of the Natural Environment

Nature exists. Humans exist. The behaviour of one impacts upon the other. The behaviour of humans is governed by the artificial contrivance described as the law. While the law can in this way control the behaviour of humans and the impact that human behaviour has on nature, the behaviour of nature is governed – if at all- in accordance with nature’s own sets of values which are quintessentially a matter for nature. The relationship between nature and humans may be the object of rules of law, but traditional legal doctrine dictates that humans but not nature are the subjects of the rules of law. The jurisprudence of the earth – it would appear – seeks to equalise in the eyes of the law nature as part of the global environment and humans as part of the global environment. How might this be done?

Assessment of damages for defamation of business and personal reputation

An award of damages for defamation is to provide reparation for harm to a plaintiff’s reputation for the publication of defamatory material, compensate for any personal distress caused and vindicate the plaintiff’s reputation.1 Assessing such damages is recognised as a difficult task and perhaps the Queensland courts face further difficulties as there are few awards of damages for defamation in the state. This was pointed out in the recent decision of the Queensland Court of Appeal, Cerutti & Anor v Crestside Pty Ltd & Anor.2 This decision examined in detail the principles of assessing damages for defamation.

Herpes simplex 2 risk among women in a polygynous setting in rural West Africa

OBJECTIVES: To determine risk factors for herpes simplex 2 (HSV2) infection in women in a polygynous rural Gambian population. METHODS: Data from women who participated in a cross-sectional survey of reproductive health were matched to their own and, for women who had been or were married (ever-married), their spouses' data collected in a cross-sectional survey of fertility interests, including information on marital histories. RESULTS: Data were available on 150 never-married and 525 ever-married women. HSV2 prevalence was 16% amongst never-married women and 36% amongst ever-married women. For ever-married women, their own personal characteristics (age, ethnicity and genital cutting status) and events from their husbands' marriage history were important determinants of HSV2 infection. Women whose husbands married for the first time over age 35 were at greater risk than women whose husbands married by age 24 [odds ratio (OR) 2.72, 95% confidence interval (CI) 1.20-6.10]. Women whose husband reported interest in a new marriage were more likely to be HSV2 positive (OR 1.91, 95% CI 1.18-3.09). Women whose husbands were currently monogamous but had had previous marriages (OR 2.76, 95% CI 1.30-5.88) and women in currently polygynous marriages (OR 2.88, 95% CI 1.66-5.01) were three times as likely to be HSV2 positive as women who were their husband's only wife ever. CONCLUSION: Much transmission of HSV2 in this setting occurs within marriage where opportunity for personal protection is limited. High levels of transmission within marriage may undermine the impact of sexual behaviour change programmes aiming to reduce HSV2 and HIV incidence and complicate their evaluation.

Contributions of the private sector to global biodiversity protection: case study of the Fortune 500 companies

Since the inception of the UN Convention on Biological Diversity (CBD) in 1992, little progress has been achieved in terms of involving the business community in protecting biological diversity worldwide. This article assesses the current activities of US Fortune 500 companies with respect to global biodiversity protection and the goals of the CBD. Data and information collected from 500 companies within eight major industrial sectors were further categorized at the company level to assess each company's involvement in global biodiversity protection. Our findings show that although companies' business profiles highly influence their decision-making process regarding the adoption of biodiversity protection policies and measures, their revenue profiles are less influential. We show that despite generating low revenues, companies in the utility sector are more active in the adoption of biodiversity protection policy than those in the financial sector, which generate high revenues. This study also demonstrates that companies must be convinced of the major effects of biodiversity loss on their bottom lines to be motivated to protect biological diversity. Companies' business and business-related risk profiles can also influence the adoption of biodiversity protection policies within the company. The study further demonstrates that a measurable biodiversity impact indicator is necessary for the companies to get seriously involved in the mitigation action. Finally, this study proposes a three-step biodiversity loss mitigation action framework that is drawn upon the assessment of the 500 companies that can contribute to develop an elaborative framework of business sector-specific mitigation plan. © 2013 Copyright Taylor and Francis Group, LLC.

China's "Responsible Protection" concept : re-interpreting the Responsibility to Protect (R2P) and military intervention for humanitarian purposes

This article assesses the extent to which the recently formulated Chinese concept of “Responsible Protection” (RP) offers a valuable contribution to the normative debate over R2P’s third pillar following the controversy over military intervention in Libya. While RP draws heavily on previous proposals such as the original 2001 ICISS report and Brazil’s “Responsibility while Protecting” (RwP), by amalgamating and re-packaging these earlier ideas in a more restrictive form the initiative represents a new and distinctive interpretation of R2P. However, some aspects of RP are framed too narrowly to provide workable guidelines for determining the permissibility of military intervention for civilian protection purposes, and should therefore be clarified and refined. Nevertheless, the Chinese proposal remains significant because it offers important insights into Beijing’s current stance on R2P. More broadly, China’s RP and Brazil’s RwP initiatives illustrate the growing willingness of rising, non-Western powers to assert their own normative preferences on sovereignty, intervention and global governance.

The Proposed Commonwealth Personal Property Securities Act 2008

Inspired by similar reforms introduced in New Zealand, Canada and the United States, the Commonwealth, with the co-operation of the States, seeks in the Personal Property Securities Bill 2008 (the Bill) to introduce a central repository of recorded information reflecting particular security interests in personal property in Australia. Specifically, the interest recorded is an interest in personal property provided for by a transaction that in substance secures the payment or the performance of an obligation. In addition to providing a notification of the use of the personal property as collateral to secure the payment of monies or the performance of an obligation, the Bill proposes to introduce a regime of prioritising interests in the same collateral. Central to this prioritisation are the concepts of a ‘perfected security interests’and ‘unperfected security interests’. Relevantly, a perfected security interest in collateral has priority over an unperfected security interest in the same collateral. The proposed mechanisms rely on the fundamental integer of personal property, which is defined as any property other than land. Recognising that property may take a tangible as well as an intangible form, the Bill reflects an appreciation of the fact that some property may have a tangible form which may act as collateral, and simultaneously the same property may involve other property, intangible property in the form of intellectual property rights, which in their own right may be the subject of a‘security agreement’. An example set out in the Commentary on the Consultation Draft of the Bill (the Commentary), indicates the practical implications involving certain property which have multiple profiles for the purposes of the Bill. This submission is concerned with the presumptions made in relation to the interphase between tangible property and intangible property arising from the same personal property, as set out in s 30 of the Bill.

Protection of intellectual property in Islamic Shari'a and the development of the Libyan intellectual property system

This thesis introduces a theory of intellectual property (IP) law informed by Islamic Shari'a. The sources and objectives of Islamic Shari'a support the theoretical framework underpinning IP laws. However, they strongly emphasise the importance of development goals in intellectual property policy making. This thesis argues that an optimal IP system from an Islamic perspective shall not overprotect IP holders but should instead endeavor to empower people to access knowledge resources to enhance access to education, public health and economic opportunities. Taking Libya as a case study, this thesis makes recommendations for the improvement of IP law that have important broader implications for developing countries.

Detection of rain in acoustic recordings of the environment

Environmental monitoring has become increasingly important due to the significant impact of human activities and climate change on biodiversity. Environmental sound sources such as rain and insect vocalizations are a rich and underexploited source of information in environmental audio recordings. This paper is concerned with the classification of rain within acoustic sensor re-cordings. We present the novel application of a set of features for classifying environmental acoustics: acoustic entropy, the acoustic complexity index, spectral cover, and background noise. In order to improve the performance of the rain classification system we automatically classify segments of environmental recordings into the classes of heavy rain or non-rain. A decision tree classifier is experientially compared with other classifiers. The experimental results show that our system is effective in classifying segments of environmental audio recordings with an accuracy of 93% for the binary classification of heavy rain/non-rain.
