A discussion of the known fossil tabanids (Diptera Tabanidae) is presented based on fossil evidence. This includes the origin of the hemathophagy in the Brachycera, more specifically for tabanids. Several tabanid species in the extant fauna are vectors for disease-producing organisms that affect humans and animals. Bacteria, viruses, rickettsiae, protozoa, and filarial worms can be transmitted ...

Xu She’s interest in engineering began elementary school, after reading One Hundred Thousand Whys . This popular science book series China, mostly intended for children, was given to him by his parents and ignited a passion that would burn brightly throughout life. It included various stories c...

In 2008, Al-Thaga and Shahzad [Generalized I-nonexpansive self-maps and invariant approximations, Acta Math. Sinica 24(5) (2008), 867{876]introduced the notion of occasionally weakly compatible mappings (shortly owcmaps) which is more general than all the commutativity concepts. In the presentpaper, we prove common xed point theorems for families of owc maps in Mengerspaces. As applications to ...

It has been observed that most first year engineering students seem to enjoy and often perform well in their project and project-oriented freshman engineering course, but seem to have difficulty and often perform poorly in their first calculus course. Working from the perception that first year engineering students do not make the connection between what they learn in calculus and the problems ...
