The optimization of heat exchanger network (HEN) synthesis still remains an open problem because of the complexity of the space comprising all the possible solutions, and most of the proposed methods introduce simplifying assumptions that mainly affect the topological features of the candidate solutions considered and thus artificially limit the boundaries of the search space. This work is devo...
Here we report a fourteen-month-old fourlegged local hen in Nigeria with two cloacae and three caeca. The hen walked with only the normal two limbs, which were larger and cranial to the extra two limbs. The extra limbs were usually suspended in the air and pointed caudally during motion, being attached to the pygostyle by cartilage and skin tissue. Investigations of the bird were carried out us...
A semiempirical shell-correction method including ellipsoidal deformations is used to determine binding energies of open-shell, unpolarized HeN clusters. Shell effects, shapes, and other ground-state properties ~like the chemical potential! are determined. HeN clusters are found to be substantially less deformed due to their relatively high surface energy as compared to that of alkali-metal clu...
Susceptibilities of 5 different mice strains, including C3H/HeN, BALB/c, C57BL6, FvB and ICR, to Echinostoma hortense infection, was evaluated. The worm expulsion rate, worm size and egg production were observed from 1 to 8 weeks after infection with 30 metacercariae. C3H/HeN and ICR mice showed the highest worm maturation rates. The worm recovery rate and the number of eggs per gram (EPG) of f...
We use a special Canadian dataset containing both literacy test scores and standard labour market variables to examine the impact of literacy on immigrant earnings. Having a literacy measure allows us to examine issues related to discrimination and the sources of lower returns to foreign acquired education and experience among immigrants. We find that the native-born literacy distribution (asse...
This study introduces the concept of ‘digital diversity’ to refer to the increasing workforce heterogeneity that stems from the recent rise of digital natives in the workforce. While digital diversity is expected to promise innovation and efficiency, it may also give rise to organizational challenges. The nature of the promise and challenge of digital diversity as well as how it is perceived ac...
This article reports key findings of a study which investigated the use of technology by 569 'digital natives' students for English Language learning and recreational purposes. Their views on the applicability of technological tools such as facebook, blogging and skype for English Language teaching and learning were also investigated. The findings showed that although the students expressed pos...
