Near-real-time biomonitoring of heavy metals using the xenoassay® system
description: Heavy metals have widespread industrial uses and have been found in increasing quantities as contaminants in all components of the biosphere. Water and sediment of rivers near industrial areas such as the Juru River in Penang and Langat River in Selangor are polluted with heavy metals. Thus, rapid and fast methods to detect the presence of heavy metals in the environment are necessary. Existing instrumental methods such as atomic absorption and emission spectrometry are very sensitive but the sole use of these instruments for heavy metal detection is extremely expensive, needs a skillful person to operate and is not amenable to near-real-time analysis. The best scenario for routine biomonitoring of heavy metals is the marriage between instrument- and bioassays. Currently, the USEPA has recognized whole cell-based bioassays such as as PolytoxTM and Microtox® for the detection of heavy metals. Unfortunately these cell-based assays cannot be used as real-time or near real-time assays in the field as they require bulky incubators. Near-real-time monitoring of heavy metals giving results in less than one hour is very useful in environmental CSI (Criminal Scene Investigation) or ECSI where temporal and spatial concentrations of heavy metals in running waters are a challenge to environmentalists to pinpoint heavy metals POS (point of source) for legal purposes. Enzyme-based inhibitive assays are simple, rapid and fast and could be developed for near real-time assays. We have developed an inhibitive assay system –Xenoassay® based on proteases for the assay of heavy metals. The system could detect the heavy metals mercury, cadmium, lead, copper, zinc and silver at the sub parts per million level. Field trial near-real-time assay capability shows promising results.

NEGOTIATING ACEH SELF-DETERMINATION IN INDONESIA’S UNITARY SYSTEM: A Study on Peace Agreement Helsinki Memorandum of Understanding 2005
description: Abstract - Aceh, the northern-most province of Indonesia came through long suffering of armed conflicts for self-determination under the Dutch (1873-1942) and Japanese colonisation (1942-1945). It continued until Aceh joined Indonesia‟s unitary system in 1945, in which it was formally initiated by Tgk. Daud Beureueh between 1953-1963, and further to be declared by Tgk. Hasan Tiro on 4th December 1976 under the banner of the Free Aceh Movement (GAM). This struggle was ended by peace agreement, the Helsinki Memorandum of Understanding (MoU) on 15th August 2005 with the Aceh self-government notion consensus. In this regard, Aceh has more spaces and opportunities to re-determine its political, economic, social and cultural status under the Indonesian system. According to the international law, the notion of self-government is considered as internal self-determination under the International Human Rights Law regime. This would refer to two covenants: the United Nations International Covenant on Civil and Political Rights and on Economic, Social and Cultural Rights 1966. However, in practice, despite this ongoing implementation has achieved some progress in short term local political development, yet there are still many challenges for long-term economic, social and cultural advancement objectives, in particular regarding human rights related issues. This paper endeavours to analyse the issue through the overview of historical background of Aceh self-determination from an international law perspective. Hopefully, this paper contributes to a conceptual understanding of the MoU Helsinki in terms of Aceh self-determination movement as well as some challenges ahead.

New Holder - Type Inequalities for the Tracy-Singh and Khatri-Rao Products of Positive Matrices
description: Recently, the authors establised a number of inequalities involving Khatri-Rao product of two positives matrices. Here, in this paper, the result are establised in three ways. First, we find new Holder-type inequalities for Tracy-Singh and Khatri-Rao products products of positive semi-devinite matrices. Second, the result are extended to provide estimates of sums of the Khatri-Rao and Tracy-Singh products of any finite number of positive semi-definite matrices. Three, the result lead to inequalities involving the Hadamard and Kronecker, as a special case.
