Intra-subsaharan African trade appears to be very low, an outcome that is often justified on the grounds of the size of the exporting and the importing economies. If that were the explanation, there would be no untapped trade potentials. We argue instead that the main determinant of this “missing trade” is geography. Being landlocked (and poor) translates(More)
M ERCHANDISE trade is by far the best documented aspect of international economic relations. Trade data therefore offer a rich source of information on patterns and shifts in the allocation of economic activity around the globe. In this paper I describe global merchandise trade flows through the lens of intra-industry trade (IIT) indices, which quantify the(More)
We recently demonstrated that a novel heterocyclic amine, 5-amino-6-hydroxy-8H-benzo[6,7]azepino[5,4,3-de]quinolin-7-one (ABAQ), is produced from glucose and l-tryptophan by the Maillard reaction at physiological temperature and pH, and that ABAQ was strongly mutagenic for Salmonella strains in the presence of S9 mix. Here, we present the results of three(More)
To clarify the seasonal fluctuations in air pollution and the effect of long-range transport, we collected airborne particles (n=118) at Dazaifu in Fukuoka, Japan, from June 2012 to May 2013 and measured Pb and SO4(2-), which are indicators of the long-range transport of anthropogenic air pollutants, as well as their mutagenicity, and other factors. The(More)
As genetic advances become incorporated into health care delivery, disparities between developing and developed countries may become greater. By addressing genetic health care needs and specific differences of developing countries, these disparities may be mitigated. We sought to describe the attitudes and knowledge of subjects with hereditary neurological(More)
The transduction of mechanical force into useful chemical reactions is an emerging design approach to impart soft materials with new functions. Here, we report that mechanochemical transductions can be achieved in metallosupramolecular polymers. We show that both reversible and irreversible reactions are possible and useful to create mechanically responsive(More)
Light-responsive supramolecular polymers were applied as reversible adhesives that permit bonding and debonding on demand features. A telechelic poly(ethylene-co-butylene) (PEB) was functionalized with either self-complementary hydrogen-bonding ureidopyrimidinone (UPy) motifs (UPy-PEB-UPy) or 2,6-bis(1'-methylbenzimidazolyl)-pyridine (Mebip) ligands(More)
Supramolecular Polymers with Orthogonal Functionality Report Title Supramolecular polymers with orthogonal interactions are of broad interest, and reports on such materials with multifunctional stimuli-responsive behavior are rare. Polymer blends based on a poly(ethylene-co-butylene) core (PEB) terminated with either 2-ureido-4[1H]-pyrimidinone (UPy)(More)
Ataxia telangiectasia (A-T) is a rare, autosomal recessive disorder of childhood characterized by progressive cerebellar ataxia, telangiectasia, and immune defects, and is caused by mutations in the ataxia-telangiectasia mutated (ATM) gene [1]. The incidence of the disease is about 1 in 40,000 to 100,000 births [2]. A-T has been reported worldwide [3], but(More)
Public concern regarding the transport of air pollutants from mainland East Asia to the leeward area by the prevailing westerlies in spring and winter monsoon has been growing in recent years. We collected total suspended particle (TSP) in Beijing, a metropolis of China located windward of Japan, in spring (late February 2011-May 2011) and in winter(More)
