1. 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.

2. 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.

3. 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.

4. 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.

5. 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.

6. 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.

7. 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.

8. 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.
