Solving Parabolic Partial Differential Equations Using Modified Bellman's Method With G-Spline Interpolation, Osama H. Mohammed Dec 2010

Solving Parabolic Partial Differential Equations Using Modified Bellman's Method With G-Spline Interpolation, Osama H. Mohammed

Baghdad Science Journal

The aim of this paper is to approximate the solution of the parabolic partial differential equations (heat equations) using Bellman's method with the cooperation of the G-spline interpolation formula. The partial differential equation will then be changed into a system of the first order ordinary differential equation. The resulting system may be then solved easily by using the fundamental matrix solution. In this paper, the Bellman's method may be considered as a generalization to the usual Bellman's method with an arbitrary ordinary derivative.

Scheduling Job Families On A Single Machine, Adawiyah A. Mahmood, Naji M. Saheab Dec 2010

Scheduling Job Families On A Single Machine, Adawiyah A. Mahmood, Naji M. Saheab

Baghdad Science Journal

The problem of scheduling n jobs on a single machine is considered, where the jobs are partitioned into several families and a set – up time is necessary between jobs of different families. The objective is to find a lower bound for the problem of minimizing the sum of completion times and the maximum tardiness. This paper uses a decomposition property to find a lower bound in order to incorporated in a branch and bound algorithm for constructing an optimal schedule.

Effect Of Vincristine And Vinblastine On Mice Spermatozoa In Vitro, Hazim I. A. Al-Ahmed

Baghdad Science Journal

The aim of this project was to study the in vitro effect of antineoplastic drugs (vincristine and vinblastine) on mice spermatozoa. Eighteen adult (age 8-9 weeks) male mice were divided into three groups equally. The animals in each group were slain by cervical dislocation, the testes were removed and two tails of epididymides isolated. Spermatozoa were obtained from the two tails of epididymides by mincing in 500 µl TCM-199.The first group non-treated (unadded) as a control group, second group added 10 µg/ml of vincristine to TCM-199 and the third group added 10 µg/ml of vinblastine to TCM-199. After 10 minutes …

A Study Of Some Biological Aspects Of Procellio Scaber(Isopoda : Porcellionidae) Latrellile 1804in Al-Jadriyia Region /Baghdad-Iraq, Haifa J. Jewaire, Suad Majeed Hassan

Baghdad Science Journal

A study of some biological aspects of the crustacean Isopod procellio scaber was carried out for the period April 2003 to march 2004 . The study consisted reproductive and morphological characteristies such as size , weight and length of the body . The result showed that the highest population density of P. scaber was 1120 individual/m2 in September 2003 and less density 403 ind/m2 in February 2004. The density was generally high in Spring and Autumn, low in Summer and Winter months.An increase of the sexual ratio appear in the females number compared to males number (p < 0.05) during most of year. Present study showed non significant increase in the length and dry weight for females compared to males in most of year months. There were two seasons for reproduction, first starts in February to the ends of August, the second season starts in September,to the end in January. A number of Juveniles recorded during most time of year. While the percentage decreased during the Winter months and nearly disappeared during December. The large size individuals dominated during the Spring season which may be due to their rapid growth. The results showed that the moult individuals in different sizes class present for most year months, in large numbers small sizes class include due to their rapid growth. Life cycle data showed four biological stages: eggs, Manca, Juvenile and Mature stages. The female put between (2-70) eggs per each breed. There is one or tow breed for female in year.

Effect Of Annealing Temperature On The Some Electrical Properties Of Insb:Bi Thin Films, Zeinab Jassim Shanan

Baghdad Science Journal

InSb alloy was prepared then InSb:Bi films have been prepared successfully by thermal evaporation technique on glass substrate at Ts=423K. The variation of activation energies(Ea1,Ea2)of d.c conductivity with annealing temperature (303, 373, 423, 473, 523 and 573)K were measured, it is found that its values increases with increasing annealing temperature. To show the type of the films, the Hall and thermoelectric power were measured. The activation energy of the thermoelectric power is much smaller than for d.c conductivity and increases with increasing annealing temperature .The mobility and carrier concentration has been measured also.

Radiative Forcing Over The Conterminous United States Due To Contemporary Land Cover Use Change And Sensitivity To Snow And Interannual Albedo Variability, Christoper A. Barnes, David P. Roy Dec 2010

Radiative Forcing Over The Conterminous United States Due To Contemporary Land Cover Use Change And Sensitivity To Snow And Interannual Albedo Variability, Christoper A. Barnes, David P. Roy

GSCE Faculty Publications

Satellite‐derived land cover land use (LCLU), snow and albedo data, and incoming surface solar radiation reanalysis data were used to study the impact of LCLU change from 1973 to 2000 on surface albedo and radiative forcing for 58 ecoregions covering 69% of the conterminous United States. A net positive surface radiative forcing (i.e., warming) of 0.029 Wm−2 due to LCLU albedo change from 1973 to 2000 was estimated. The forcings for individual ecoregions were similar in magnitude to current global forcing estimates, with the most negative forcing (as low as −0.367 Wm−2) due to the transition to forest and the …
