Aspects of the life-cycle energetics of two subspecies of dunlin calidris alpina

Dunlin from two breeding populations, C.a.schinzii from Iceland and C.a.alpina from northern Scandinavia, were studied during and after migration through Teesmouth, north-east England, and in captivity. C.a.schinzii winters in north-west Africa and has a much longer migration pathway than C.a.alpina which winters in Britain and around the North Sea. Measurements of Resting metabolic Rate (RMR) were made for the two subspecies of Dunlin in March and November in order to establish the relationship between resting metabolic rate and temperature and hence energy costs of living at different temperatures (20 C - 0 C). Energy costs of living in C.a.alpina were 21% higher than C.a.schinzii. Measurements of Basal Metabolic Rate (BMR) were made for the two subspecies (before, during and after moult) in conjunction with measurements of body compositions using Total Body Electrical Conductivity (TOBEC) in order to estimate the costs of moult. Energy costs of moult were 1692 KJ for alpina and 1016 KJ for schinzii.Energy costs of migration were estimated by measuring the amount of fat laid down before departure by wild Dunlin of the two populations, with the aid of Total Body Electrical Conductivity (TOBEC). Energy costs of migration were estimated as 3489 KJ for alpina, and 5156 KJ for schinzii. Energy costs of egg production and incubation were estimated from other workers’ studies of other (similar) species. Energy costs of egg production were only 220 KJ for the two subspecies whereas the costs of incubation were 1232 KJ and 1143 KJ in alpine and schinzii, respectively. In contrast to the suggestion by Drent and Piersma (1990), I have found that the costs of migration are considerably less than the costs of living. Also the total annual energy cost for those Dunlin wintering in colder areas i.e. C.a.alpina is much higher than for those wintering in tropical regions i.e. C.a.schinzii. Energy costs are not the only factors that affect a bird's lifetime output of young. C.a.alpina uses a different migration strategy to C.a.schinzii but may breed on better breeding grounds, and hence achieve more successful reproduction

Certain triple q-integral equations involving third Jackson qq-Bessel functions as kernel

In this paper, we employ the fractional $q$-calculus in solving a triple system of $q$-Integral equations, where the kernel is the third Jackson $q$-Bessel functions. The solution is reduced to two simultaneous Fredholm $q$-integral equation of the second kind. Examples are included. We also apply a result in~[Pacific J. Math. \textbf{275}(1) (2015)63--102] for solutions of dual $q^2$-integral equations to solve certain triple integral equations

Determinants of Internet Financial Reporting : An Empirical Investigation on UAE Public Listed Companies

The main purpose of this study is to provide insights into the use of Internet for disseminating financial information among UAE publicly listed companies and to put some lights on the factors that affect such companies in adopting financial disclosure through internet. The findings show that UAE companies are still to some extent placed behind those in other developed countries and even with other developing countries. This study additionally examined the effect of three factors namely firm size, leverage and profitability on internet financial reporting (IFR). A linear regression analysis is applied for this purpose. Findings reveal that profitability and leverage do not significantly influenced internet financial reporting. The result also shows that there is a significant positive linkage between the amount of financial disclosure through internet and size of companies

Blended E85-diesel fuel droplet heating and evaporation

The multidimensional quasi-discrete (MDQD) model is applied to the analysis of heating and evaporation of mixtures of E85 (85 vol % ethanol and 15 vol % gasoline) with diesel fuel, commonly known as “E85–diesel” blends, using the universal quasi-chemical functional group activity coefficients model for the calculation of vapor pressure. The contribution of 119 components of E85–diesel fuel blends is taken into account, but replaced with smaller number of components/quasi-components, under conditions representative of diesel engines. Our results show that high fractions of E85–diesel fuel blends have a significant impact on the evolutions of droplet radii and surface temperatures. For instance, droplet lifetime and surface temperature for a blend of 50 vol % E85 and 50 vol % diesel are 23.2% and up to 3.4% less than those of pure diesel fuel, respectively. The application of the MDQD model has improved the computational efficiency significantly with minimal sacrifice to accuracy. This approach leads to a saving of up to 86.4% of CPU time when reducing the 119 components to 16 components/quasi-components without a sacrifice to the main features of the model

THE COMPELLING NECESSITY OF HOUSING AS A MEANS OF TERMINATING THE LEASE

This study deals with the compelling necessity of housing as a means of terminating the lease, which is a permit or a means granted by the legislator or the judiciary to the owner to repossess their property as a result of the realization of an emergency circumstance. To meet the aim of the current study, a comparative analytical approach is taken into account. Given the results,  the right of the owner to repossess the property by compelling necessity is restricted by not to abuse the right in order to preserve the rights of the tenant for the purposes of housing. In fact, these restrictions, which violation constitute an abuse, are represented in the absence of the intent of abusement, that the desired benefit of the act is illegitimate and that the benefit from the same is not commensurate with the harm that afflicts others in addition to not going beyond the status established by the customs and traditions

Development of a conjugate heat transfer solver

The current research study presents a numerical approach in modelling the conjugate heat transfer system of the gas-turbine rotating discs-cavities. The work was undertaken to understand such phenomena and, more specifically, to numerically investigate the thermal interactions in rotating discs-cavities. The developed solver is capable of dealing with complex heat transfer problems, such as unsteady three-dimensional compressible rotating-flows. The development was based on integrating an inhouse computational fluid dynamics code (SURF) with a heat conduction solver internally. Method of interpolation using mapped area was also introduced for treating non-matching meshes at interface, which plays an effective role in exchanging boundary data. This thesis also documents the development of a numerical finite volume cell-vertex hybrid edgebased heat conduction code by the author using FORTRAN. The heat conduction solver was developed and validated to deal with three dimensional solid-domains using unstructured elements. The validation process was carried out on several test cases for investigating the temperature distribution. The test results were presented to show good agreement with the analytical, experimental and other commercial numerical solutions where they exist
