[en] The text of the Protocol Additional to the Agreement between the Government of the Republic of Malawi and the International Atomic Energy Agency for the Application of Safeguards in Connection with the Treaty on the Non-Proliferation of Nuclear Weapons is reproduced in this document for the information of all Members. The Board of Governors approved the Additional Protocol on 23 November 2006. It was signed on 5 May 2007 in Lilongwe, Malawi, and on 26 July 2007 in Vienna, Austria
[en] Highlights: • Systems approach modelling of residues-based bioenergy system demonstrated for the first time. • Sources of dynamics in primary forest residues-based bioenergy systems have been identified. • Steady availability of mature stands simulated over a time horizon of 100 years is presented. • Systems integration is critical for sustainability of forest residues-based bioenergy. - Abstract: Lack of access to modern energy, such as electricity, liquid fuels and gas, limits socio-economic development in developing countries, particularly in rural communities. Primary forest residues are potential bioresources for producing modern forms of energy beyond traditional biomass, which can be supplied to economic activities in the rural communities. However, variations in production of primary forest residues over time exacerbate sustainability challenges for developing sustainable bioenergy systems based on the residues supply chains integrated with timber production. A model is presented showing dynamics of primary forest residues, as bioenergy feedstocks, stemming from forest plantations management, harvesting systems, and stakeholder influence and interest along the bioenergy production value chain. Using a case study of the Viphya forest plantations established for timber production in Malawi, management and harvesting systems, sawmilling technologies, residues production and post harvesting management were assessed and key sustainability challenges along the residues supply chain have been identified. The decreasing stocks of mature stand over time results from over-exploitation for timber production, delayed replanting, high death rate of replanted trees and underinvestment in plantations management. An integrated framework for forest management and bioenergy production can promote sustainable harvesting of mature stand for timber and primary forest residues production through synchronization of harvesting and replanting of timber and establishment of thresholds for harvesting timber to generate residues at a rate that can match with the scale and rate of the bioenergy conversion. The framework can promote stability, availability and reliability of timber and primary forest residues supply for bioenergy production.
[en] Highlights: • Radiographers had average infection control scores for knowledge and practice. • A significant association between age and knowledge was found. • Need for training and a specific guideline for infection control in radiology departments in Malawi was identified. - Abstract: IntroductionAdherence to standard infection control precautions (SICP) by radiographers is critical in combating healthcare associated infections (HAIs). Therefore, radiographers need to have adequate knowledge and practices of infection control if they are to contain the magnitude of HAIs.
[en] Land clearing and forest sector residues, notably the wastewood generated on large timber plantations, can provide a sizeable and hitherto neglected source of woodfuel. This article highlights experience in Malawi where wastewood from pine plantations is converted into charcoal that is sold to residential, industrial and agro-industrial users. Similar initiatives proposed in other countries of sub-Saharan Africa indicate that comprehensive utilization of wastewood resources could help to reduce regional and local imbalances.

[en] Nine rare earth elements (REEs) in African carbonatite samples were determined by instrumental neutron activation analysis (INAA). The geochemical behavior of REEs in carbonatites, especially REE pattern (chondrite-normalized), is studied in relation to carbonatite formation at the Kangankunde Mine, Malawi. REE-rich phosphate minerals, particularly monazite, and the other unusual minerals such as strontianite, are observed during the stages of carbonatite formation. Four kinds of carbonatites exhibit similar chondrite-normalized REE distribution patterns in spite of the marked difference of their REE contents. All these carbonatites are characterized by the strong fractionation between light and heavy REEs and by the very high La/Yb ratio (1000-2800). (author)s
