In this paper, the restricted least squares method is employed to estimate the parameters of the Cobb-Douglas production function and then analyze and interprete the results obtained. A practical application is performed on the state company for leather industries in Iraq for the period (1990-2010). The statistical program SPSS is used to perform the required calculations.
A protocol has been developed for micropropagation of Arachis hypogea L. under in
vitro conditions. Nodal explants gave rise to multiple shoots when cultured on MS medium
supplemented with different concentrations of BA (benzyladenine) with Kin (Kinetin) or GA3
(gibberellic acid). The highest response of shoot multiplication was obtained in MS
containing 1.5 mg.l¯¹ BA and 0.5 mg.L¯¹ Kin. The regenerated shootlets were rooted on MS
(Murashige and Skoog) basal medium with different concentrations of IBA (indolbutyric
acid) and IAA (indol acetic acid). The highest response of rooting was achieved with IBA at
0.05 + IAA at 0.05 mg.L¯¹. The maximum frequency of rooting and highest number of roots
Theoretical calculations are achieved to study the effect of different deuterium pressures on various characteristics parameters for PF400J plasma focus using an international computer code. Axial and radial velocities, voltage tube, plasma temperatures, and neutron yields at different operating deuterium pressures are computed. Neutron emission has been calculated in the device. The maximum total neutron yield calculated is of the order of and neutrons per shot for entire pressure used. The computed results agree reasonably well with the published neutron yield curves.

Expressions for the Bias, Mean Squared Error [MSE( )] and Relative Efficiency [R.Eff.( )] of proposed estimators are derived. Numerical results and conclusions are drawn about selection different constants including in these expressions. Comparisons between suggested estimators with respect to usual estimators in the sense of Relative Efficiency are given. Furthermore, comparisons with the earlier existi

In situation where the experimentations are time consuming or very costly, a Double Stage procedure can be used to reduce the expected sample size needed to obtain the estimator. This estimator is shown to have smaller mean squared error for certain choice of the shrinkage weight factor y( ) and for acceptance region R. Expression for

A playwright, director and filmmaker, he has written more than thirty plays for the stage and seven original screen plays for cinema and TV (Susan Emerling, p.1). He began his dramatic career in the late sixties. Along with such dramatists as Howard Brenton and Trevor Griffiths, he writes in the aftermath of the "Angry Young Men" tradition of John Osborne. It is a well-known fact that the element of anger continued in the drama of the 1960s and became even more radicalized after the social, cultural and political unrests of 1968 by the dramatists of the "second wave" to whom Hare belongs (John Russell Taylor, p.14).

The alcoholic extract of MP leaves at a dose of 150mg/kg B.W and 300 mg/kgB.W showed antinociceptive effects in different methods, where the dose of 300 mg/kg B.W showed significant reduction of the nociception by acetic acid. In the formalin test, the extract (300mg/kg B.W) also significantly reduced painful stimulus in both phases of the test. Treatment with extract (300mg/kg B.W) when given orally produced significant increase of the reaction time in hot plate test. These results showed that the leaves extract of MP contain active analgesic principles acting both centrally and peripherally.

Paronomasia is a recognized rhetorical device by which poets could play with words that are similar or identical in form but different in meaning. The present study aims to identify paronomasia in Arabic and English. To achieve the aim of the study, a corpus of selected verses chosen from two famous figures in Arabic and English literatures and analyzed thoroughly. The analysis of data under investigation reveals that paronomasia is a crucial aid used by poets to portrait the real world as imaginative. It further shows that the concept of paronomasia in English is not the same as in Arabic. In English, there are echoes of the Arabic jinās, i.e., there are counterpart usages of similar devices, yet English rhetoricians have not defined or c
