Anticyclone of synoptic studies that influence weather and climate of Iraq, The aim of
the study is to clarify the effect variation of repetition of Anticyclone and effect on thermal
characteristic in Iraq were pressure level has been analyzed (1000) millibars and that because
of pressure level is the closet to the earth surface and the clarity of climatic phenomenon
based on a systematic analysis of synoptic seeking maps and observation and (12:00)
according to timing GMT for five climatic stations which is (Mosul, Kirkuk, Baghdad, Rutba,
and Basra) and so far three consecutive climatic cycles which is first climatic cycle for period
(1986-1976). and second climatic cycle for period (1997-1987) and third climatic cycle for
period (2008-1998).It become clear from the result. That study reach, It become clear that a clear depression
in repetition of Anticyclone from climatic session to another climatic session followed by
three climatic session and on all level of study area stations. The contrast repetition of
Anticyclone is one of the factors that help to raise the temperature due to air stillness and the
clarity of the sky that led to the concentration of pollutant and slow in their transition to other
areas. These pollutant increase rising temperatures air textures to the surface of earth because
it absorb ground radiation at night and reflect it to surface of earth as well as the clarity of the
sky during the day helped to increase the amount of solar radiation to the earth it is found
rising temperatures Siberian is the station (Mosul, Kirkuk, Rutba) for October month for
second climatic cycle for period (1997-1987) and third for period (2008-1998) as well as
increase temperatures maximum rate with increasing repetition rate of high semi-orbital in the
stations Mosul, Kirkuk, and Rutba area for each month of January and October in the second
climatic session for period (1997- 19987) as well as in the third climatic cycle for period
(2008-1998) in all stations of studying area for months of January and march and October and
the high rate of maximum temperature with high rate repetition of European Anticyclone in
all stations of studying area in the second climatic cycle for period(1997-1987) 0f January,
march, October months, Notice increase repetition rate of Siberian Anticyclone in the month
of October for two climatic cycle second and third as well as Basra station recorded increase
in minimum temperature rate with increase repetition rate of high semi-orbital in the second
climatic cycle for period (1997-1987) for January as well as in all stations of studying area in
the third climatic cycle for period (2008-1998) for march also in stations of Mosul, Kirkuk,
Basra for two climatic cycle the second and the third for October. And high rate of minimum
temperature with high repetition rate of European Anticyclone in the stations of Kirkuk and
Basra in January for the second climatic cycle period (1997-1987) as well as recorded in
march month in stations of Mosul and Kirkuk, Basra for two climatic cycle the second and
third also in October for the second climatic cycle for stations of studying area.

Nuclear emission rates for nucleon-induced reactions are theoretically calculated based on the one-component exciton model that uses state density with non-Equidistance Spacing Model (non-ESM). Fair comparison is made from different state density values that assumed various degrees of approximation formulae, beside the zeroth-order formula corresponding to the ESM. Calculations were made for 96Mo nucleus subjected to (N,N) reaction at Emax=50 MeV. The results showed that the non-ESM treatment for the state density will significantly improve the emission rates calculated for various exciton configurations. Three terms might suffice a proper calculation, but the results kept changing even for ten terms. However, five terms is found to give

The matrices were prepared by either dry granulation(slugging) , or wet granulation method using chloroform as a solvent evaporation vehichle. The cumulative release was adjusted by using polyvinylpyrollidone (PVP) or ethylcellulose (EC) polymers .The results indicated that both methods of preparation were valid for incorporation PTX as a sustained release granules .Moreover ,the results revealed that best polymer used was Eudragit RSPM in 3:20 polymer drug ratio .Besides to that , the results indicated that the release profiles were affected by pH- medium&

Abstract
Magnetic abrasive finishing (MAF) process is one of non-traditional or advanced finishing methods which is suitable for different materials and produces high quality level of surface finish where it uses magnetic force as a machining pressure. A set of experimental tests was planned according to Taguchi orthogonal array (OA) L27 (36) with three levels and six input parameters. Experimental estimation and optimization of input parameters for MAF process for stainless steel type 316 plate work piece, six input parameters including amplitude of tooth pole, and number of cycle between teeth, current, cutting speed, working gap, and finishing time, were performed by design of experiment

In this study, the effect of fire flame on the punching shear strength of steel fiber reinforced concrete flat plates was experimentally investigated using nine half-scale specimens with dimensions of 1500×1500 mm and a total thickness of 100 mm. The main investigated variables comprised the steel fiber volume fraction 0, 1, and 1.5% and the burning steady state temperature 500 and 600 °C. The specimens were divided into three groups, each group consists of three specimens. The specimens in the first group were tested with no fire effect to be the reference specimens, while the others of the second and third groups were tested after being exposed to fire-flame effect. The adopted characteristics of the fire test were; (one hour) b

In this work, silicon nitride (Si3N4) thin films were deposited on metallic substrates (aluminium and titanium sheets) by the DC reactive sputtering technique using two different silicon targets (n-type and p-type Si wafers) as well as two Ar:N2 gas mixing ratios (50:50 and 70:30). The electrical conductivity of the metallic (aluminium and titanium) substrates was measured before and after the deposition of silicon nitride thin films on both surfaces of the substrates. The results obtained from this work showed that the deposited films, in general, reduced the electrical conductivity of the substrates, and the thin films prepared from n-type silicon targets using a 50:50 mixing ratio and deposited on both

The taxonomy of Ficus L., 1753 species is confusing because of the intense morphological variability and the ambiguity of the taxa. This study handled 36 macro-morphological characteristics to clarify the taxonomic identity of the taxa. The study revealed that Ficus is represented in the Egyptian gardens with forty-one taxa; 33 species, 4 subspecies and 4 varieties, and classified into five subgenera: Ficus Corner, 1960; Terega Raf., 1838; Sycomorus Raf., 1838; Synoecia (Miq.) Miq., 1867, and Spherosuke Raf.,1838; out of them seven were misidentified. Amongst, four new Ficus taxa were recently introduced to Egypt namely: F. lingua subsp. lingua Warb. ex De Wild. & T. Durand, 1901; F. pumila L., 1753; F. rumphii Blume, 1825, and F. su
