Review of tropospheric bomb C-14 data for carbon cycle modeling and age calibration purposes

Comprehensive published radiocarbon data from selected atmospheric records, tree rings, and recent organic matter were analyzed and grouped into 4 different zones (three for the Northern Hemisphere and one for the whole Southern Hemisphere). These C-14 data for the summer season of each hemisphere were employed to construct zonal, hemispheric, and global data sets for use in regional and global carbon model calculations including calibrating and comparing carbon cycle models. In addition, extended monthly atmospheric C-14 data sets for 4 different zones were compiled for age calibration purposes. This is the first time these data sets were constructed to facilitate the dating of recent organic material using the bomb C-14 curves. The distribution of bomb C-14 reflects the major zones of atmospheric circulation.

Estimating the specific heat capacity of starch-water-glycerol systems as a function of temperature and compositions

Increasing interests in the use of starch as biodegradable plastic materials demand, amongst others, accurate information on thermal properties of starch systems particularly in the processing of thermoplastic starch (TPS), where plasticisers (water and glycerol) are added. The specific heat capacity of starch-water-glycerol mixtures was determined within a temperature range of 40-120degreesC. A modulated temperature differential scanning calorimeter (MTDSC) was employed and regression equations were obtained to predict the specific heat capacity as a function of temperature, water and glycerol content for four maize starches of differing amylose content (0 - 85%). Generally, temperature and water content are directly proportional to the specific heat capacity of the systems, but the influence of glycerol content on the thermal property varied according to the starch type.

No pain, no gain? Torture and ethics in the war on terror

Is the use of torture ever justified? This article argues that torture cannot be justified, even in so called ticking bomb cases, but that in such extreme situations it may be necessary. In those situations, judgements about whether the use of torture is legitimate must balance the imminence and gravity of the threat with the need to prevent future occurrences of torture and maintain a normative environment that is hostile to its use. The article begins by observing that the use of torture and/or cruel and degrading treatment has become a core component of the global war on terror. It tests the claim that the use of coercive interrogation techniques does not constitute torture, showing that similar arguments were levelled by both the British and French governments in relation to Northern Ireland and Algeria respectively and found wanting. It then evaluates and rejects Dershowitz's claim for the legalization of torture and the more limited claim that torture may be permissible in ticking bomb scenarios. In the final section, the article questions how we might maintain the prohibition on torture while acknowledging that it may be necessary in some hypothetical cases.
