This paper uses Labor Force Survey data for European countries to estimate national investment in assets, where the asset boundary is extended beyond that software and databases as currently defined System of National Accounts. We find that: (a) 2011–2018, 1.4 percent EU-28 employment was engaged formation (software and) with a mean growth rate 5 per annum; (b) on average 2011–2016, expanding r...

Little is known about the incidence or pattern of congenital heart disease in tropical Africa, except for the description of 15 cases found among 4220 newborn children in Ibadan, Nigeria (Gupta and Antia, 1967), and a report of 44 patients who attended a paediatric cardiology clinic in Kampala, Uganda (Caddell and Connor, 1966). The purpose of this paper is to describe the cases of congenital h...

Infant botulism is a rare disease that affects infant less than 12 months of age. The illness results from absorption of botulinum toxin produced in situ by neurotoxigenic clostridia that can temporarily colonize the intestinal tract of infants. To date, all inhabited continents except Africa have reported cases of infant botulism. Recognition of cases seem directly related to physician awarene...

The evolution of yellow fever virus over 67 years was investigated by comparing the nucleotide sequences of the envelope (E) protein genes of 20 viruses isolated in Africa, the Caribbean, and South America. Uniformly weighted parsimony algorithm analysis defined two major evolutionary yellow fever virus lineages designated E genotypes I and II. E genotype I contained viruses isolated from East ...

Piezoelectric motors are used in many industrial and commercial applications. Various piezoelectric motors are available in the market. All of the piezoelectric motors use the inverse piezoelectric effect, where microscopically small oscillatory motions are converted into continuous or stepping rotary or linear motions. Methods of obtaining long moving distance have various drive and functional...
