A vortex domain wall's(VW) magnetic racetrack memory's high performance depends on VW structural stability,high speed, low power consumption and high storage density. In this study, these critical parameters were investigated in magnetic multi-segmented nanowires using micromagnetic simulation. Thus, an offset magnetic nanowire with a junction at the center was proposed for this purpose. This junction was implemented by shifting one portion of the magnetic nanowire horizontally in the x-direction(l) and vertically(d) in the y-direction. The VW structure became stable by manipulating magnetic properties, such as magnetic saturation(M_(4)) and magnetic anisotropy energy(K_(u)). In this case, increasing the values of M_(4) ≥ 800 kA/m keeps the VW structure stable during its dynamics and pinning and depinning in offset nanowires,which contributes to maintenance of the storage memory's lifetime for a longer period. It was also found that the VW moved with a speed of 500 m/s, which is desirable for VW racetrack memory devices. Moreover, it was revealed that the VW velocity could be controlled by adjusting the offset area dimensions(l and d), which helps to drive the VW by using low current densities and reducing the thermal-magnetic spin fluctuations. Further, the depinning current density of the VW(J_(d)) over the offset area increases as d increases and l decreases. In addition, magnetic properties, such as the M_(4) and K_(u),can affect the depinning process of the VW through the offset area. For high storage density, magnetic nanowires(multisegmented) with four junctions were designed. In total, six states were found with high VW stability, which means three bits per cell. Herein, we observed that the depinning current density(J_(d)) for moving the VW from one state to another was highly influenced by the offset area geometry(l and d) and the material's magnetic properties, such as the M_(4) and K_(u).

Objectives: This study aims to describe birth weight and its variations concerning maternal characteristics as well as to standardize birth weight curves for Qatari and expatriate’s newborn population born in the state of Qatar. Methods: PEARL-Peristat registry is a National maternal-neonatal observation epidemiologic database project where both maternal and neonatal cohort data are collected to evaluate specified outcomes for a population defined by a disease, conditions, or exposures. Results: Out of 50,535 singleton deliveries, only 44,178 live-born infants were included in this study. The LBW rate has remained constant since 2011 and was reported as 2.4% in males and 3.5% in females. The average total LBW was 3%. The lowest incidence of LBW was seen in maternal age between 30 - 45 years. There was a marginal increase in the i

In this study, the application of sodium bentonite(SB) in formulation of tablets prepared by direct compression for oral administration was tested. Three different model drugs with different solubilities: paracetamol, diclofenac sodium and metformin HCl were tested. Each drug was mixed with SB at ratio of 50% and the mixtures were subsequently *** studies were conducted using both Deferential Scanning Calorimeter(DSC)and Fourier Transform Infrared Spectroscopy(FTIR). The dissolution profile for each drug was determined in USP-buffers at different time intervals. Diclofenac sodium in pH 6.8 buffer and paracetamol in both pH 6.8 and pH 4.5 buffers showed extended release. However,metformin HCl showed immediate release at the different pH values. The study showed that using SB was possible to prepare tablets with different release profiles. However, these profiles differ depending on dissolution media and drug type.

GIS is a computerized database management system that provides geographic access (capture, storage, retrieval, analysis and display) to spatial data. Civil Engineering projects involve the management, analysis and integration of large amounts of geographic information to ensure success. This can include a wide range of information such as detailed design drawings originating from CAD solutions, detailed mapping, air photography, geological investigations, population information, traffic flows and environmental models. although there are some similarities between CAD and GIS there are many differences. The most fundamental difference is that GIS mode is the world as it exists, whereas CAD models artifacts yet to be produced. As a result the data manipulated by a GIS is an order of magnitude larger and more complex than CAD systems have to deal with, and the nature of the data, its sources and its uses are quite different. In this paper, the selected area was Nahrain University. Many data were saved on the site map as a transparence layers built by using AutoCAD (2006). Then a digital library was built for the selected area and many data were saved on the site map as a themes built by using ArcView software.
