This thesis is an investigation of the relevance of ‘people's war’ to contemporary Chinese defence policy. This loose concept has been eroded by 'modernity’, but a guerilla-based defence remains the essential theme. Prior to China's acquisition of nuclear weapons, people's war was the sole element of the state's deterrent policy, aiming to swamp an invader with China's numerical strength. In the 1980s and beyond people's war finds effectiveness through a combination of materiel of middle range technology and the traditional usage of massive manpower. People's war under modern conditions remains essentially defensive, but now incorporates 'active defence’ with accent on greater mobility. However, the central thesis of this work relates to how the traditional strategy may influence nuclear doctrine. This thesis proposes that China could abandon long-range ballistic missiles and adopt a new concept in nuclear strategy: that of, Guerilla Nuclear Warfare. Trained in guerilla tactics and equipped with battlefield nuclear weapons, this would represent the logical extension of China's people's war strategy to the new nuclear conditions associated with superpower research into space-based ballistic missile defences and which, in full deployment, could nullify a Chinese nuclear deterrent based only on 'mid-tech' delivery systems. Guerilla Nuclear Warfare, as a strategy, would involve the irregular use of locally held and controlled tactical nuclear weapons, but it would also be a method of circumventing the proposed Soviet missile defence shield by not challenging it. Guerilla Nuclear Warfare does not exist in the late 1980s, but evidence exists to suggest its development. It cannot yet be proven as the new direction but China's strategic circumstances add weight to available indications: unless the Strategic Defence programs of the established superpowers are arrested then it appears the sole option available to the Chinese for the maintenance of a nuclear deterrent in the early part of the 21st Century.

Information infrastructures are an eclectic mix of open and closed networks, private and public systems, the Internet, and government, military, and civilian organisations. Significant efforts are required to provide infrastructure protection, increase cooperation between sectors, and identify points of responsibility. The threats to infrastructures are many and various, and are increasing daily: information warfare, hackers, terrorists, criminals, activists, and even competing organisations all pose significant threats that cannot be sufficiently dealt with using the current infrastructure model. We present a National Information Infrastructure model that is based on defence against threats such as information warfare.

Research into Intelligent Agent (IA) technology and how it can assist computer systems in the autonomous completion of common office and home computing tasks is extremely widespread. The use oflA's is becoming more feasible as the functionality moves Into line with what users require for their everyday computing needs. However, this does not mean that IA technology cannot be exploited or developed for use in a malicious manner, such as within an Information Waifare (IW) scenario, where systems may be attacked autonomously by agent system implem-entations. This paper will discuss tne cilrrenlStcite Ofmalicious use of lA's as well as focusing on attack techniques, the difficulties brought about by such attacks as well as security methods, both proactive and reactive, that could be instated within compromised or sensitive systems.

This paper examines the ethics of the practice of information warfare at both the national and corporate levels. Initially examining the present and past actions of individual hackers, it moves to the more organised, future military and economic warfare scenarios. It examines the lack of legal or policy initiatives in this area.

The synthesis and complete characterisation of the fluorescent ligand, 4-acridinol-1-sulphonic acid (the acridine analogue of 8-quinolinol-5-sulfonic acid) is described. Using a judicious array of nuclear magnetic resonance spectroscopy experiments, the structural elucidation and full assignment of all proton and carbon chemical shifts were afforded. The 4-acridinol-1-sulphonic acid was found to behave in a similar manner to 8-quinolinol-5-sulphonic acid, forming fluorescent complexes with magnesium(II) and zinc(II). The uncorrected emission maxima for the metal–acridinol complexes were found to be at around 620 nm compared to 505 nm for the respective quinolinol complexes. Unfortunately, preliminary spectrofluorimetric analytical figures of merit revealed that the detection limits of the new acridinol metal complexes were one and a half orders of magnitude poorer than those attained with the corresponding quinolinol ligand. However, in contrast to 8-quinolinol-5-sulphonic acid, the 4-acridinol-1-sulphonic acid ligand showed considerable selectivity for magnesium(II) and zinc(II) over aluminium(III).

An acute bout of exercise increases skeletal muscle glucose uptake, improves glucose homeostasis and insulin sensitivity, and enhances muscle oxidative capacity. Recent studies have shown an association between these adaptations and the energy-sensing 5' AMP-activated protein kinase (AMPK), the activity of which is increased in response to exercise. Activation of AMPK has been associated with enhanced expression of key metabolic proteins such as GLUT-4, hexokinase II (HKII), and mitochondrial enzymes, similar to exercise. It has been hypothesized that AMPK might regulate gene and protein expression through direct interaction with the nucleus. The purpose of this study was to determine if nuclear AMPK α2 content in human skeletal muscle was increased by exercise. Following 60 min of cycling at 72 +/- 1% of VO2peak in six male volunteers (20.6 +/- 2.1 years; 72.9 +/- 2.1 kg; VO2peak = 3.62 +/- 0.18 l/min), nuclear AMPK α2 content was increased 1.9 +/- 0.4-fold (P = 0.024). There was no change in whole-cell AMPK α2 content or AMPK α2 mRNA abundance. These results suggest that nuclear translocation of AMPK might mediate the effects of exercise on skeletal muscle gene and protein expression.

The continuing erosion of civil liberties in Western democracies, and in particular Australia, as a response to the threat of terrorist attack - the position taken that laws eroding civil liberties will ultimately fail in its attempt to combat terrorist activity while adding to human insecurity and violence - counter-terrorism measures resulting in the militarisation of law enforcement and provoking terrorism - linking counter-terrorism with globalisation.

A nuclear exclusion appears in all general insurance policies. Since its introduction to Australia and New Zealand in the 1960s this exclusion has seen almost no change. So what are the reasons for this article? There are two reasons. First, there has been a misunderstanding on the part of some in the industry about the scope of this exclusion. This results in unnecessary alterations to the policy. The other is that a new wording is emerging some sections of the market which could be tar-reaching in its effect. The purpose of this article is to examine several aspects related to the exclusion. The first section examines the nature and extent of exposures in relation to radiation and nuclear energy and serves as background to under standing the exclusion wording. Section two provides the reasons for the inclusion of the clause and its historical origins. Section three addresses the intended scope of the current exclusion and the final section examines the scope of a new wording that is appearing and the possible implications that may result.

A simple model peroxyoxalate chemiluminescence system was monitored directly across a range of temperatures (from −80 to +20 °C) using 13C nuclear magnetic resonance spectroscopy. These experiments were made possible by the utilisation of 13C doubly labelled oxalyl chloride, which was reacted with anhydrous hydrogen peroxide in dry tetrahydrofuran. Ab initio quantum calculations were also performed to estimate the 13C nuclear magnetic resonance (NMR) shift of the most commonly postulated key intermediate 1,2-dioxetanedione and this data, in concert with the spectroscopic evidence, confirmed its presence during the reaction.

Proton nuclear magnetic resonance spectroscopy (NMR) has shown the potential for being a valuable tool in monitoring a commercial fermentation. In this preliminary study, a suite of organic analytes including ethanol, fructose, glucose, methanol, glycerol, malic acid, tartaric acid, succinic acid, acetic acid and lactic acid were simultaneously determined during the fermentation. Data collection and analysis using chemometric algorithms aided the understanding of key processes including the effects of seeding a wine with bacteria for malo-lactic fermentation.

With information warfare (IW) becoming a reality, the need for a new security methodology to deal with the new and unique attack threats and vulnerabilities associated with the new information technology security paradigm. With the shift from computer security to information warfare, logical transformation models (LTMS) were looked at as a solution to quantifying information system requirements. The paper will introduce the concepts involved with fourth generational models and it's application to IW. The basic advantages and disadvantages will also be discussed and presented.
