Accelerating the Modified Picard Iteration By Using Green's Function Approach
Ahmed, Mufeedah Maamar
We consider the Picard's iteration method as a technique for solving initial value problems of the first and second order linear differential equations. The basic idea is the use of Green's function to collect some of the terms in a perfect differential term, and then use the decomposition techniques. For the second order differential equations, we transform the equation to a system of two first order equations and in addition, we use the Gauss Seidel technique. The algorithm of the proposed method is discussed. Comparisons with the classical Picard method and modified Picard have illustrated the rapid convergence of the proposed method. Numerical examples have illustrated that the technique obtains the theoretical fixed point quicker than that obtained with other techniques including the modified Picard

A NEW CMOS DESIGN AND ANALYSIS OF CURRENT CONVEYOR SECOND GENERATION (CCII)
SHAKTOUR, MAHMOUD AHMED; OKASHA, AlAA YOUSEF
This paper describes the current conveyors used as a basic building block in a variety of electronic circuit in instrumentation and communication systems. Today these systems are replacing the conventional Op-amp in so many applications such as active filters, analog signal processing. Current conveyors are unity gain active building block having high linearity, wide dynamic range and provide higher gain bandwidth
The proposed current conveyors are simulated using TSMC 0.18μm CMOS technology on Advanced Design System and the results are also tabulated for comparison. The main features of these current conveyors are low voltage, less power, high slew rate and wide bandwidth for voltage transfer (Vy to Vx) and current transfer (Ix to Iz) which make them suitable for high frequency and low power applications

Semantic Repetition in Translating between Arabic and English
AL Sharif, Mohammed A
Languages are important medium for communication between nations. They are naturally distinctive. Arabic and English are among these languages which belong to two distant language families. Arabic is a Semitic language whereas, English is Anglo – Saxon. Accordingly, they are different. Several linguistic features pose variable problems when translating between these two languages. Semantic repetition in Arabic is among the problems which encounter professional as well as trainee translators when translating from Arabic into English. Despite the attempts by many translation researchers to deal with the problems encountered translators when translating, only a few investigated the problem of semantic repetition in Arabic This paper is an attempt to shed light on this translation problem using examples to illustrate it and explore the possible techniques suggested by translation scholars to tackle this and help to produce satisfactory translation to the target language reader of English. The discussions in this paper, could provide a point of reference for many translation researches throughout the Arab world.

Context: The severe side effects of analgesic drugs require the search of new analgesics from natural products and nutritional resources known as nutraceutical.
Objective: This work aimed to evaluate the analgesic effect of fresh pomegranate Punica granatum fruit juice (fpj) been consumed by Libyans for a century. In this study we investigated the fresh fruit juice given to mice for three subsequent days versus the effect of (fpj) given instantly and those given the ethanol extract of pomegranate
Materials and Methods: Antinociceptive activity of fresh pomegranate fruit juice (fpj) was examined using two models of pain. In the writhing test the (fpj) was administered for three subsequent days where no food was given,the (fpj) was also given instantly i.p.(0.15ml/kg) and orally p.o.(0.15ml/kg) for hot tail one group of animals were prefed (fpj) the ethanol pomegranate extract was administered by intraperitoneal route in doses of (100,150 and 200mg/kg) for writhing , hot tail flick test and compared to aspirin 100mg/kg in all tests
Results:
In the writhing test for mice the index of pain inhibition (IPI) was 47.8% for mice prefed with (fpj) and 37% for ethanol pomegranate extract (200mg/kg i.p.) and 59% for aspirin whereas,the groups treated instantly (0.15ml/10g) i.p.and orally failed to inhibit acetic acid induced writhings.
In the hot-tail flick test fresh pomegranate fruit juice (fpj) antinociceptive effect was evident within 15min the maximum possible analgesia ( MPA) was 18% and remained elevated throughout the observation period ethanol pomegranate extract (200mg/kg) showed significant analgesia reaching its peak at 60 min MPA was 24.1% as compared to aspirin 37.5%
Conclusion: The results demonstrated that consuming pomegranate fresh fruit leads to significant analgesic activity which may be both peripheral and central.
