This study was conducted to estimate the activity of crude extracts of the horseradish and nettles, turmeric plant and a combination of these combined plants extracts for the treatment of heavy metal pollution like zinc and cobalt that accumulate in fish by adding them to fish provender. This experiment was carried out during the September, October, November months, by using 40 gold fish that distributed in five basins, the heavy metals ratio (zinc and cobalt) were determined in the bodies of fish before the pollution in each basin. It has been added salts of zinc and cobalt to the basins in order to getting the concentration ratio 10 mg/L for each of the metals in the basins water, after 14 days have been re-determining of the concentration of metals in the basins and before the treatment. Attended three crude plants extract by using alcohol and water, as well as detection of the active compounds that may exist in plant extracts That showed the horseradish extract contains alkaloids , terpenes , saponins , flavonoids, resins , glycosides , coumarins and tannins, while the nettles extract and turmeric extract contains the alkaloids , flavonoids , saponins, resins, tannins and glycosides. also, the toxicity test was carried out for determine the toxicity of extracts, which proved that the crude extracts were non-toxic, then, from the crude extracts were prepared a different concentrations with the singly form and blended to remove a pollution from the bodies of the fish in the four basins, while, The fifth basin was used as a control basin that a provender was added to it only. After 14 days, the concentration of zinc and cobalt were determined in bodies of fish, the concentration of zinc was ranging from 1.7810 mg/L to 2.4527 mg/L, while the cobalt concentration was ranging from 0.0582 mg/L to 1.436 mg/L. The treatment was continued for 21 days, after that, heavy metal salts were determined in the bodies of fish. The concentration of zinc was from 0 mg/L to 2.0950 mg/L and cobalt was 0 mg/L. These results showed the existence of significant differences among the heavy metals concentrations in bodies of fish for different basins after 21 days of treatment. As it is shown by the results that the nettle extract was more efficient in the removal of zinc from the fish tissue. While, the horseradish extract was more efficient in the removal of cobalt from the fish tissue.
Mobile Wireless sensor networks have acquired a great interest recently due to their capability to provide good solutions and low-priced in multiple fields. Internet of Things (IoT) connects different technologies such as sensing, communication, networking, and cloud computing. It can be used in monitoring, health care and smart cities. The most suitable infrastructure for IoT application is wireless sensor networks. One of the main defiance of WSNs is the power limitation of the sensor node. Clustering model is an actual way to eliminate the inspired power during the transmission of the sensed data to a central point called a Base Station (BS). In this paper, efficient clustering protocols are offered to prolong network lifetime. A kern

Show MoreThe research is concerned with studying the characteristics of Sustainable Architecture and Green Architecture, as a general research methodology related to the specific field of architecture, based on the differentiation between two generic concepts, Sustainability and Greening, to form the framework of the research specific methodology, where both concepts seem to be extremely overlapping for research centers, individuals, and relevant organizations. In this regard, the research tend towards searching their characteristics and to clearly differentiates between the two terms, particularly in architecture, where the research seeks understanding sustainable and green architectures, how they are so close or so far, and the

Decision-making has three approaches according to the opinions of most of the writers and researchers in the administrative area: an analytical approach, intuitive approach and behavioral approach. This research is trying to discover the nature of the relationship in terms of the link between the impact of each of these approaches and efficiency of marketing services by selecting an intentional sample of 58 researches from the Directorate General of Traffic, one of the Iraqi Interior Ministry ins

Background: The nasofrontal angle is the angle between the forehead & dorsum of the nose, it is of prime importance in giving the shape of the nose in relation to face. Workers studied this angle in living individuals, in this work, the angle was measured on dry human skulls, in addition, its value was statistically correlated with certain facial parameters.
Objectives: Determination of the value of nasofrontal angle in human skulls & correlation of this value to other facial parameters, namely; length of nasal bone, nasion height & midfacial length as these parameters are important for surgeons working in rhinoplasty.
Methods: The nasofrontal angle & other facial parameters were measured ca
The administrative authority (the administration) exercises its activity or work through two forms of business. This administrative act in which the intention of the administrative authority (the administration) is to have a specific legal effect. The risk, and whether the administration is restricted or discretionary in exercising its authority in the licensing area, it must not deviate from the legitimacy framework.
Accordingly, and to be informed of this, we divide our study into three sections, in the first of which we deal with the definition of administrative licenses, and in the second of it we explain the competent authority for administrative licenses in comparative law, and in the third we highlight the authority concer
