Missing data are pervasive, and pose problems for many statistical procedures. We all should be using methods that treat missing data properly, rather than deleting data or using single imputation. Importantly, it is not dif?cult to implement these missing data. A relatively few absent observations on some variables can dramatically shrink the sample size. As a result, the precision of confidence intervals is harmed, statistical power weakens and the parameter estimates may be biased. In this paper we used EM method that aims to estimate Missing Values, and summarizes how to apply out EM method to estimation missing data using SPSS.

English and Arabic belong to two different languages families Germanic and Semitic, therefore difficulty will definitely arise. Since style is the manner or the way that somebody usually writes, so it plays an important role in affecting the meaning of any translated text. Some style features of both languages pose problems in translation from Arabic into English or vice versa. Arab students should know that English style is not identical with Arabic style so we cannot translate in a straightforward way. Style difference in origins causes a difference in meaning and creates wide gaps for translators when translating. This study aims at discussing style, showing the differences between Arabic and English style, introducing different style and suggest suitable correct and. Because style plays an important role in affecting the meaning of any translated text Also the study shows style for university students of AL-Baha University, College of Science and Arts, Department of English Language 2016-2017 during the second semester.

In this paper, a new algorithm for noise suppression schemes is applied to specific practical problem mainly the suppression of Binary phase-shift keying (BPSK) level of the modulated signal. This is a practical situation of modulation which is used in different transceivers schemes such as in Digital Video Broadcasting (DVB) or other types of modulation techniques with standard microwave systems. The algorithm is well suited for a modular software radio concept, which we believe, will be more accepted in the future of wireless communication. Further modifications of the scheme necessary for these applications are described, and the results are presented to illustrate performance improvements. A general interpretation of this technique based on multiplying the transmitted data vectors by a generated amplitude matrix (AM) in the transmitter side, and the inverse of amplitude matrix (IAM) in the receiver side algorithm are introduced and discussed. The suggested scheme results are compared with the conventional modem through using BPSK type of modulation. Different gains are obtained from the proposed model relevant with the conventional system in AWGN and flat fading channel, according to the variation of the adjusted parameters.

The collimator is the most important part in the installation of the Prompt Gamma Activation Analysis (PGAA). This collimator will be installed around the lateral Channel of the Moroccan TRIGA MARK II research reactor. The main purpose of this work is using the Monte Carlo simulation via the MCNP5 code to design the new collimator of the prompt gammas installation, to determine the optimal thickness of the bismuth (Bi) filter for gamma radiation. The obtained results of the collimator design and its filter are analyzed and discussed.

The Finite Elements Method (FEM) analysis is very helpful in solving a wide variety of engineering problems. An application of finite elements method ranges across many different fields of modern science and of the manufacturing industry. The various applications in aircraft, space, ship building, the electrical and computer industry as well as in the field of science such as material engineering, mechatronics, biochemistry and even medicine must be emphasized. FEA of simulation gives better, more accurate and wider results than experimental methods. One of the examples of FEA application is strain analysis of joints and assembly structures of vehicles of machineries. It allows the kind of stresses occurring in the vehicles and the location their occurrence to be determined. In this study, a methodology of sequentially simulating each step in the manufacturing process of an assembly is proposed. Each step of the proposed methodology is described, and a validation of the prediction capabilities is performed by making a comparison with a physically manufactured assembly. The work presented here demonstrates that by using virtual prototyping it is possible to predict the final shape of an assembled structure. The trial and error development process may be shortened by replacing most of the physical try out with finite element simulation of the manufacturing process. The automotive industry is constantly looking at ways and means of reducing costs and staying profitable while delivering on time. The common denominator in all these challenges is design. Companies investing in developing indigenous design and manufacturing technologies emerge successful in the world market and are able to sustain and innovate at a faster pace than the rest of the competition. This is possible on account of the following capabilities such as delivering products faster with up-front engineering design validation as a part of the product development process while compressing the cycle time, lean design by incorporating value engineering as a part of the design process ensuring evaluation of least cost alternatives before even the first prototype is developed and increasing reliability by design – an initiative that will eliminate hidden costs associated with product recall, re-design and/ or replacement of parts. Increasing functional complexity, predatory pricing, compulsive cost reduction commitments, aggressive deadlines, field failures, warranty costs and product recalls are all too familiar situations in the automotive sector. This leads to greater innovation, process automation, shorter development cycles, design for durability, reduced physical prototypes, improved quality and innovation.

Noise generally is known as unwanted and unwelcome sound. It is considered as the most pervasive pollutant besides the emission pollutants. Along with the increasing degree of air and water pollution, noise pollution is also emerging as a new threat to the inhabitants of Al-Samawah city. Al- Samawah city experienced rapid development and high influx of people with the implication of increased generation of noise. Hence the need to evaluate the noise pollution level of the city. Measurement of noise pollution level was carried out in 20 locations around the city using a GM1351 digital sound level meter with a range of 30-130 dB. Day-time urban noise quality assessment was studied in Al-Samawah city for six critical zones viz. Industrial , Commercial, Residential, Recreational ,Silence zone and Traffic areas. Noise pollution indices viz. L10, L50, L90, noise climate (NC), equivalent continuous noise level (Leq) and noise pollution level (Lnp) were computed for all zones. Excel's computer program used for fitting model equations to the obtained experimental data. Results indicated that the highest Leq of 72.5 dB in the industrial zone followed by 70.0 dB in traffic areas ,68.1 dB was observed in commercial zone, 65.2 dB in residential zone ,63.5 dB in silent zone, and 62.4 dB in recreational zone. For commercial zones, Leq observed were down the statutory limits, while for other zones it was above the WHO limits. The noise assessment study clearly revealed that the Industrial and residential zones caused noise pollution in Al-Samawah city and silence areas need attention and care from the institutions to be silent zones. As excessive noise affects health of people deleteriously, the establishment of an agency under the name of Iraqi Environmental Protection Agency (IEPA) is essential for controlling this and similar hazards.

The objective of the present study was to minimise the unwanted side effects of olanzapine (OZ) drug by kinetic control of drug release by entrapping OZ into gastro resistant, biodegradable waxes such as beeswax (BW), cetostearyl alcohol (CSA), spermaceti ( SP) and fat cetyl alcohol ( CA) microspheres using meltable emulsified dispersion cooling induced solidification technique utilizing a wetting agent. Solid, discrete, reproducible free flowing microspheres were obtained. The yield of the microspheres was up to 94.0%. Microspheres had smooth surfaces, with free flowing and good packing properties, indicating that the obtained angle of repose, % Carr’s index and tapped density values were well within the limit. More than 97.0% of the isolated spherical microspheres were in the particle size range of 312-330 µm as confirmed by scanning electron microscopy (SEM) photographs. The drug loaded in microspheres was found to be stable and compatible with waxes as confirmed by DSC and FTIR studies. The release of drug was controlled for more than 8 h. Intestinal drug release from microspheres was studied and compared with the release behaviour of commercially available formulation Olanex®. The release kinetics followed different transport mechanisms. The drug release performance was greatly affected by the materials used in microsphere preparations, which allows absorption in the intestinal tract.
