AIM Insufficient oxygen supply to organs and tissues due to reduced arterial or venous blood flow results in ischaemia, during which, although ATP production stops, AMP and adenosine continue to be produced from ATP. The fate of irisin, which causes the production of heat instead of ATP during ischaemia, is unknown. Iloprost and sildenafil are two pharmaceutical agents that mediate the resumpti...

There is a protracted stalemate between rich (the North) and poor (the South) countries over the question of minimum labour standards in developing economies. This paper is a sequel to Singh and Zammit (2000). It considers afresh key issues in the controversy. While fully recognizing the moral, political and philosophical dimension of this complex issue, the paper concentrates on the central ec...

This paper proposes a 60GHz quadrature PLL frequency synthesizer that has a tuning range capable of covering the whole band specified by the IEEE802.15.3c with exceptional phase noise. The synthesizer is constructed using a 20GHz PLL that is coupled with a frequency tripler to generate the 60GHz signal. The 20GHz PLL generates a signal with a phase noise as low as −106dBc/Hz using tail feedback...

Working conditions for the majority of the world's workers do not meet the minimum standards and guidelines set by international agencies. Occupational health and safety laws cover only about 10 percent of the population in developing countries, omitting many major hazardous industries and occupations. With rare exception, most countries defer to the United Nations the responsibility for intern...

Reusing learning material is very important to design learning environments for real-life learning. The reusability of learning objects results from the product of three main features: modularity, discoverability and interoperability. We proposed learning objects built based on agent architectures, called Intelligent Learning Objects (ILO). This paper discusses how the ILO approach can be used ...

Training, productivity and labour competencies in organisations Concepts, Methodologies and Experiences " Leonard Mertens MERTENS, L. Training, productivity and labour competencies in organisations: concepts, methodologies and experiences. The designations employed in ILO publications, which are in conformity with United Nations practice, and the presentation of material therein do not imply th...

The People’s Republic of China has ratified four of the eight core ILO labour Conventions. In view of severe restrictions on trade union rights and the prevalence of child labour and forced labour as well as discrimination, determined measures are needed to comply with the commitments WTO members accepted at Singapore, Geneva and Doha in the WTO Ministerial Declarations over 1996-2001, and in t...
