Microwave losses of nanostructure Li-Ni ferrites in X-band and Ku-band
...Show More Authors

The molar ratio(x) of Li-Ni ferrites in the formula Li0.5-0.5xNixFe2.5-
0.5xO4 was varied in range 0.1-1.0 by hydrothermal process. The
XRD, SEM, and TEM tests were conducted to examine the samples
crystalline phase and to characterize the particles shapes and sizes.
The high purity spinel structure was obtained at med and high x
values. SEM and TEM images showed the existence of different
ferrite particles shapes like nanospheres and nanorods. The
maximum particle size is around (20nm). These size encourage
occurrence of super paramagnetic state. The reflection loss and
insertion loss as microwave losses of Li-Ni ferrite-epoxy composite
of 1mm thickness and mixing ratio 39.4 wt was investigated. The
minimum reflection loss in x-band and in Ku band was about -8dB
around 10GHz and lower than -18dB respectively. The insertion loss
exceeded -6dB in the two band for some samples.

2D and 3D Modeling of Rock Mechanical Properties of Khasib Formation in East Baghdad Oil Field
...Show More Authors

Knowing the distribution of the mechanical rock properties and the far field stresses for the field of interest is an important task for many applications concerning reservoir geomechanics, including wellbore instability analysis, hydraulic fracturing, sand production, reservoir compaction, and subsidence. A major challenge with determining the rock's mechanical properties is that they cannot be directly measured at the borehole. Furthermore, the recovered carbonate core samples for performing measurements are limited and they provide discrete data for specific depths.

   The purpose of this study is to build 2D and 3D geomechanical models of the Khasib reservoir in the East Baghdad oil field/ Central area. TECHLOG.2015.3 softwa

Designs of Children's Bedroom Furniture and the Percentage of Its Use in Developing their Aesthetic Sense
...Show More Authors

The research aims to identify the bedroom furniture designs for children who are in ages range between (4-6) years and the rate of employing them in developing their aesthetic sense. To achieve this objective, the researchers developed the two research tools represented by a analysis-description form of bedroom furniture designs included a number of domains that were represented in the shapes, colors, and sizes of the furniture, as well as the availability of the safety factor, ease of use, cleaning and movement. As for the aesthetic sense scale included (30) paragraphs and alternatives (always, sometimes, never), they were distributed among a representative sample of (170) mothers of children were chosen randomly from (17) kindergartens

Public Governance and Sustainable Development - A descriptive study of the reality of public institutions in Iraq
...Show More Authors

In light of crises, the need for efficient and flexible public administrations to make quick and decisive decisions, also institutions capable of directing the internal elements and components of them and adapting them to the requirements of rapid change due to crises and disasters, which led to scarce resources becoming scarcer and economic, political and social problems becomes more prominent. For the majority of developing countries, including Iraq, the increasing need for the importance of moving towards enhancing the efficiency of the performance of public institutions while trying to predict their future, can only be achieved. Through solid mechanisms and principles of governance that enhance the ability of institutions and make them

The Efficacy of Polidocanol foam Sclerotherapy in Treatment of Infantile Hemangioma and Slow-Flow Vascular Malformation
...Show More Authors

Background: Sclerotherapy is a simple treatment modality for treatment of infantile hemangioma and slow-flow vascular malformations; Polidocanol is a mild sclerosing agent that is traditionally used in treatment of varicose veins. This study aims to evaluate the effectiveness, treatment outcome, and complications of polidocanol foam sclerotherapy for infantile hemangioma and slow-flow vascular malformations. Materials and methods: Between March 2013 and December 2014, seventeen patients with infantile hemangioma and slow-flow vascular malformations treated with polidocanol 1% foam sclerotherapy. Foam was prepared by Tessari’s method. Injection performed under general or local anesthesia, injections were repeated (if necessary) on mon

Evaluation of Sticky Traps and Baits in Control of Melon Fly, Dacus frontalis Becker on Melon
...Show More Authors
Abstract<p>The <italic>Dacus frontalis</italic> Becker is known species, being an agricultural pest. It has been attacked <italic>Cucumis melo</italic> L. Sticky traps and baits have been used as one of effective integrated control methods to monitor different types of insects. It is way to know population density of insects. For sticky traps, the average number of adults of insects caught in yellow, Transparent, blue and red traps was 15.72, 9.50, 4.67, 3.17 adults\ trap\ six weeks respectively. However, for baits, results have been recorded that average numbers of adults caught in traps were 13.67, 10.00, 9.17, 7.75, 50.6, 2.50 adult/trap. The results have been recorded tha</p> ...

The changes in the thickness of 1000 – 500 MB and it effects the climate of Iraq
...Show More Authors

This research paper is about synoptic climate specifically with in the upper air layers
using upper air layers maps analysis which are maps of thickness for the level 1000 – 500
MB, that their high average ranges between 100 – 5600 M above surface. This research paper
focuses on studying special and temporal variations of the atmosphere thickness above Iraqaccording
to this study, it is concluded that atmosphere thickness above Iraq increases
towards south with an average of 100 M as compared with north of Iraq. Regarding the
temporal variations, it is concluded that atmosphere thickness during hot months. In July, for
example, the atmosphere thickness becomes thicker than in January with an average of
(250)M
