Two patients with sectorial optic atrophy and homonymous, horizontal sectoranopia are described. Neuroradiological investigations localised the visual pathway lesion to the lateral geniculate body. The peculiar nature of the field defect and the optic atrophy appeared explicable in terms of ischaemia in the territory of the lateral choroidal artery.

We study Lp-theory of second order elliptic divergence type operators with measurable coefficients. To this end, we introduce a new method of constructing positive C0-semigroups on Lp associated with sesquilinear (not necessarily sectorial) forms in L2. A precise condition ensuring that the elliptic operator is associated with a quasi-contractive C0-semigroup on Lp is established.

The relationship between research productivity and economic growth is the subject of information science which deals in this study to examine the impact of number of publications, research & development (R&D) expenditures and researchers involved in R&D activities on economic growth in the World’s largest regions for the period of 1980–2011. The study further expanded the research-growth nexus ...

Health inequalities often result from social inequities, and those, in turn, are generated by social determinants of health (SDoH). Hence, to reduce health inequalities, it is necessary to consider all health-related determinants. Disadvantages arise even before birth, and they tend to accumulate throughout an individual's life. Thus, policy actions intended to overcome these health inequalitie...
