DOUBLE SOLITON SOLUTIONS FOR THE (2+1)-DIMENSIONAL GENERALIZED BROER-KAUP SYSTEM |
|
by Amal M. Elshaer |
|
Abstract |
In this article, the extended
coupled sub-equations expansion method has been used to construct a series of double
solution-like solutions, double triangular function solitons and complexiton solitons
for some nonlinear partial differential equations
via the (2+1)- dimensional Generalized Broer-Kaup System. With the help of symbolic computation as Maple,
we obtain many new types of double soliton solutions, i.e. various combination of
trigonometric periodic function and hyperbolic function, various combination of
trigonometric periodic function and rational function, various combination of hyperbolic function
and rational function.

DETERMINATION OF IRON CONTENT IN PORTULACA, DATES AND GREWIA |
|
by Nibras Ahmed Elaas Nour Eldaim & Abdelrahman Hassan Elnadi
|
|
Abstract |
In this investigation
three Sudanese plants products were studied with the aim of determining the iron
content in each, since these products were used by natives as rich sources of iron
content. The three plant products were: portulaca, commonly known as Riglah; grewia,
commonly known as godaim and dates which are commonly known as Balah (Barakawi ).
The technique
employed in this investigation was atomic absorption spectrometry. A striking feature
of the data obtained is that the amount of iron present in them is dramatically
different although the general and wide spread belief is that they are all very
rich in this element. Thus the amount of iron found in portulaca was 100 mg/kg,
in dates was 20 mg/kg and only 10 mg/kg in grewia.
Although other
plant products may have iron in varying amounts, but this choice for the present
investigation is mainly due to the native belief that these are the three popular
iron rich products.
It can be concluded
that scientific methods of determining the actual amounts of a particular element
needed by human body for healthy growth can only be provided through this path way.
A detailed discussion is provided for farther detailed.

PARASITIC INSECTS AND MITES AS POTENTIAL BIOCONTROL AGENTS FOR A DEVASTIVE PEST OF TOMATO, Tuta absoluta Meyrick (LEPIDOPTERA: GELECHIIDAE) IN THE WORLD: A REVIEW |
|
by Karem Ghoneim |
|
Abstract |
The tomato leafminerTuta absoluta is extremely difficult to control using
chemical insecticides because larvae mine within plant tissue and are thus protected
at least from contact insecticides.Also, larvae have an ability to develop resistance
to insecticides and thus its control is quite challenging. Thus, parasitoids are
a very important component of the natural enemy complex of T. absoluta and
have been the most common type of natural enemies introduced for biological control
of it. In the present review, the importance of different egg-, larval- and pupal-parasitoids,
belonging to several insect orders and families, as well as some Pyemotidae mites,
was discussed. Research efforts and application works for biocontrol of T. absolutain
European, North African and Middle East countries, as well as the native home, South
American countries, had been reviewed. Some considerations were presented, such as the parasitism mechanisms, factors affecting the parasitic efficiency, interference
or interaction between parasitoids and some other natural enemies, side-effects
of synthetic and botanical pesticides on parasitoids and conservation of indigenous
natural parasitoids of T. absoluta.

RELIABILITY FORECAST FOR A SOLAR PHOTOVOLTAIC (PV) SYSTEM INTEGRATED WITH GREENHOUSE BY EMPLOYING ALGEBRA OF LOGICS |
|
by Amit Kumar & Neelam Yadav |
|
Abstract |
In this paper, the author has been considered
an solar photovoltaic (PV) system integrated with greenhouse system to analysis
its stochastic behaviour and estimate the reliability by Boolean function technique.
The authors have used algebra of logics and Boolean function technique for the purpose of formulation of mathematical model and its solution. Reliability and M.T.T.F.
for the system have evaluated. Some particular cases have also given to improve practical utility of the model. Graphical illustration followed by a numerical example
has appended in last to highlight the important results of study. It is Observered
that reliability of the system decreases rapidly in case, when failures follow Weibull
time distribution, while it decreases smoothly and in better way when failures follow
exponential time distribution.

CHROMATOGRAPHIC SEPARATION AND IDENTIFICATION OF SOME VOLATILE OILS, ORGANIC ACIDS AND PHENOLS FROM THE SEEDS OF CUMINUM CYMINUM GROWING IN IRAQ |
|
by Fanar Hashum Yousif Al-Hashemi |
|
Abstract |
The current study was carried out for separation and identification
of some active constituents from Cuminum cyminum fruit (often called seeds)
were collected in unripe, fully ripe stage and investigated of these essential oils
(Octanol, Limonene, Thymol, Anisyl alcohol, Cuminaldehyde, Anethole, Vanillin and
also Benzoic acid), organic acids (Aspartic, Citric, Malic, Tartaric, Propionic,
Ascorbic, Oxalic, Maleic and Fumaric acids) and phenols (Salicylic acid, Gallic
acid, Cinnamic acid, Hydroquinone, Resorcinol, P-hydroxybenzoic acid, Rutin, Coumarine,
Quercetin). The essential oils were investigated by Gas Liquid Chromatography (GLC),
while quantitative identification of individual target organic acids and phenolic
compounds were achieved by high-performance liquid chromatography (HPLC). Moreover
the high percentage oil (10.97%) and the major components were presented as Cuminaldehyde
(14.27%), Vanillin (2.76%) and Anethole (1.93%) in the fully ripe stage of seeds.
Also the essential oil was studied for its physical properties. Many organic acids
were identified in fully ripe seeds in eight compounds comparative with unripe seeds.
Salicylic and gallic acids were showed with a highest amounts in both stage of harvest
seeds.

HYPER-RAYLEIGH SCATTERING AND SURFACE-ENHANCED RAMAN SCATTERING STUDIES OF PLATINUM NANOPARTICLE SUSPENSIONS |
|
by M. Eslamifar |
|
Abstract |
Platinum
nanoparticles (ptNPs) in the water are synthesized by nanosecond pulsed laser ablation
of a pure platinum plate in the distilled water. Using hyper-Rayleigh scattering
(HRS) spectroscopy is observed considerable HRS responses. Pt nanoparticles do not
have visible-region plasmon absorption, do not represent clear HRS signals, whereas
surprisingly, they exhibit strong surface-enhanced Raman scattering.

HALL CURRENT EFFECTS ON A FLOW IN A VARIABLE MAGNETIC FIELD PAST AN INFINITE VERTICAL, POROUS FLAT PLATE |
|
by Mark O. Okongo, Gichohi P. Nderitu & James M. Mugambi |
|
Abstract |
In this study, natural convection flow of
an incompressible fluid past an infinite vertical flat plate in a variable magnetic
field has been investigated. The research is done to find the effects of Hall current
on primary and secondary velocities of a fluid. In this case the flow is considered
as steady and restricted to laminar domain. The equations governing the flow are
solved numerically using finite difference method. The difference equations are
then solved iteratively for various values of Hall current parameter ranging from
0.0 to 1.0. This study shows that an increase in the Hall current affects the velocity
of the fluid.

PREDICTION AND ANALYSIS OF THE BALANCE OF SAVINGS DEPOSITS OF RESIDENTS BASED ON ARIMA |
|
by Pan Hong Fu & Ai Ke Feng |
|
Abstract |
In this paper,
for the past thirty years resident RMB savings deposits increased and the consumption rate is decreasing as the background, we use SAS software to establish[1] the ARIMA model
to make a short-term prediction of the future trend of concern for China’s high
savings deposits. The results showed that residents predicted RMB savings deposits
will continue to rise in the short term. At last, we give our own analysis of this
phenomenon.
