Two different photosystems for performing bacteriochlorophyll-mediated photosynthetic energy conversion are employed in different bacterial phyla. Those bacteria employing a photosystem II type of photosynthetic apparatus include the phototrophic purple bacteria (Proteobacteria), Gemmatimonas and Chloroflexus with their photosynthetic relatives. The proteins of the photosynthetic reaction cente...

BACKGROUND Urinary incontinence is a major problem faced by many mothers and has been traditionally linked to diverse ways of delivery. However, there is still a lack of clinical data, which can corroborate this notion. Thus, the present study was conducted to evaluate the correlation of urinary incontinence developed in women under different modes of delivery that have been used during childbi...

In the ECOOP’97 conference, the author of the present paper investigated a conservative extension, called Ob+1<:, of the first-order Object Calculus Ob1<: of Abadi and Cardelli, supporting method extension in presence of object subsumption. In this paper, we extend that work with explicit variance annotations and selftypes. The resulting calculus, called Ob+s<:, is a proper extension of Ob+1<:....
