In this study, mesoporous silica (MPS) is made using the sol-gel method from a cheap source (Na2SiO3) using the surfactant hydroxycetyl hydroxyethyl dimonium chloride as a template. The task is the adsorption-based removal of the medication metoprolol (MP) at concentrations between 10 and 50 ppm. Variables such as: contact time, dose of adsorbent, starting concentration of adsorbate, and adsorption temperature were studied which show the equilibrium time and adsorbent dose are 40 min and 0.05 g respectively. The Langmuir, Freundlich, Temkin, and Dubinin-Radushkevich isotherm models were fitted to the data obtained from the experiments. Comparing the outcomes showed that, of the four investigated isotherm models, the Freundlich equation m

The dimensions of bubbles were measured in a stirrer tank electrochemical reactor, where the analysis of the bubble size distribution has a substantial impact on the flow dynamics. The high-speed camera and image processing methods were used to obtain a reliable photo. The influence of varied air flow rates (0.3; 0.5; 1 l/min) on BSD was thoroughly investigated. Two types of distributors (cubic and circular) were examined, and the impact of various airflow rates on BSD was investigated in detail. The results showed that the bubbles for the two distributors were between 0.5 and 4.5 mm. For both distributors at each airflow, the Sauter mean diameter for the bubbles was calculated. According to the results, as the flow rate raised, the bubb

Background: Regional anesthesia is a common procedure in an adult patient undergoing ophthalmic surgery, but it cannot be done alone in the pediatric age group. General anesthesia is accompanied by complications intra- and post-operatively.

Objectives: to determine whether or not using regional anesthesia in combination with general anesthesia in pediatric eye procedures improves patient outcomes.

Methods: Forty children, with an age range of 6 - 12 years were included in the study that was conducted at Ghazi Al-Hariri Hospital / Department of Ophthalmology and Ibn Al-Haytham (Ophthalmology Hospital), both teaching hospitals, from December 2018 to October 2019. These childr

Fabric design is one of the arts in which humans participate functionally and aesthetically. Researching its design aspects is an important goal, especially after taking technical developments to cover many of its fields. Modern designs emphasize the importance of preparing designs and implementing them according to the child’s ability, inclinations and desires (mental, psychological and emotional). ), as the child is the real focus of the design idea, and the designer has paid most of his attention to the requirements and needs of this stage (childhood stage) because of its importance in the life of society, as he focused his attention on implementing designs that could achieve stability and stability in the child’s psyche through s

Allah the Almighty has honored many of his slaves in the high houses for their efforts in building the scientific edifice of this nation, by demonstrating what is needed from the legal provisions for all the relations between them, and the actions that they emanate from. The tasks of the abbreviations and Almstsot, and deposited in the mabahith after various investigations and precious precious matters and showed all the human needs in his life and what is expected to happen, even on the rarest possibilities, and their efforts that left the nation on the cases of Goliath. , And Ask They are in Dar dignity with the best creatures and make us a share of those good things, and Odamna to obey Him and His pleasure until death, and forgive us

This matter demands protecting economy from the acquisition on it by the holding companies with their influential impacts as a willingness to dominate and control the other companies which could lead to the disruption of the principle of equality among the shareholders in the financial and administrative rights because some persons follow several methods of control over the activity of the acquisition- targeted companies  and the confiscation of the rights of others resulting in a negative impact if accompanied by a lack of transparency and disclosure by holding companies. The holding company, whether directly or indirectly, may control a company's administration or other companies' administration leading to expansion in acquisition

Following the political development in Iraq Since 7112 exposed kind of political traditions about how to manage the conflicts that have different Iraqi powers .That what was clear since the formation of permanent government since in 7112 .
The case of conflict between political powers in administrating Iraq state and the withdrawal of American Forcesintroduces questions:
0-Is it possible that that the beginning of Iraq state building shall ease this conflict and peacemaking in the post-conflict period?
7- To what extent the Iraqi powerswas to manage their disputes in non-military like elections which was held in 7112?
2- What is the range of the extent of the political operation after the American withdrawal?
The important

The tax legal system, with its rules relating to imposing and assessing the tax and how to collect it, is one of the issues that the taxpayer is keen to follow-up on and caring about, but the aforementioned system is contested by two conflicting interests, the taxpayer’s interest in the view of a money-cutter and a means of always depriving of his wealth to the tax-imposing authority that It seeks to ensure the regular and steady flow of financial resources to the public treasury, which necessitates the presence of a judicial body entrusted with the task of securing a balance between these two conflicting interests from issues that consider themselves strongly in the tax field. It is one of the oldest human rights and public freedoms,

Gender has considered and become a new trend in women's studies, as it reflects the behaviors, roles and attitudes imposed by society on its members in accordance with their biological nature,with focusing on gender rather than on concentration on women, which is closely linked to the vision that concentrates on women's problems which are not primarily according to their biological differences But rather to a greater extent to social, cultural, historical and religious barriers and Obstacles.
Therefore, the qualitative division due to the concept of "gender" is not a rigid biological division, but is relied on the broad general context through which the social division of work is done. Thus, content in the pages of Facebook with high-
