Colloidal Silver Filters are simple devices used for home water treatment on ‎the basis of physical treatment that do not require power supply. Colloidal ‎Silver Filters utilization a vessel, mud candle, or nipping made of pored ‎ceramic material like to conventional ceramic nominee.‎
However in colloidally silver candidate , colloidal silver is use to promote ‎the hindering microorganism, bacteria and another types of microbes. ‎
The filter assembly contained two vessel : the upper vessel carry the ceramic ‎plated with colloidally silver , filters the water , and murder the bacteria and ‎the microorganism, and the lower vessel saves treated water. ‎
Colloidal silver filters removes turbidity and pathogens from drinking water.‎
Colloidal silver candidate can be built with locally prepared materials , that ‎can contribute to expanding of local trade.‎

The current study aimed at identifying the effect of negotiation skills in ‎meeting management among department heads and the teaching staff at the ‎College of Pure Education / Dhi-Qar University, in order to achieve the ‎goals pursued where the researcher used the descriptive approach that is ‎characterized by field study and through which she distributed a ‎questionnaire to find the relationship and influence of research variables ‎Included in the first variable, negotiation skills from which two skills were ‎chosen, namely the skill of influence and persuasion and the communication ‎skill corresponded to the management of meetings after verifying the ‎validity of the questionnaire used and the validity of stability, as this ‎questionnaire was applied and distributed to A sample consisted of (82) ‎academic persons distributed between heads of departments and teaching ‎staff at the College of Pure Education / Dhi-Qar University. Significant ‎significance between the search variables.‎

Molecular imprinting technology (MIT) is the technology of composition ‎a molecular lock to match a molecular key that complementary to the ‎template in shape, size, positions and arrangement of the functional ‎groups . Molecular imprinting technology can be used as ideal materials ‎in various application fields ,such as solid-phase extraction (SPE), liquid ‎chromatography, capillary electro chromatography, binding assays and ‎biosensors. The aim of this review paper is to give a fundamental ‎description of the molecular imprinted polymer and to give the reader an ‎insight into the main developments in this technique , Particular emphasis ‎will be placed on their role as affinity materials in chemical/biological ‎sensing, separation science and drug delivery. This review described first ‎general aspects in MIP history and then dealing with various application ‎aspects.‎

The satellite image classification system intends to distinguish between the classes ‎being present in the image. It is highly challenging because the coverage area of the ‎satellite is large such that the classes appear so small, this makes the process of ‎object distinguish complex. Additionally, the classification accuracy is an important ‎factor, which the classification system must pass through . This work presents a ‎satellite image classification system which can classify between the vegetation, soil ‎and water bodies ,etc. Satellite image classification needs selection of appropriate ‎classification method based on the requirements .In this paper the Support Vector ‎Machine (SVM) and (K-means) are applied on classification of high resolution and ‎low resolution satellite images. Several different performance measures ,including ‎time ,accuracy, sensitivity and simple contextual information were evaluated. ‎Additionally , the image was segmented using k-means method in order to improve ‎the classification accuracy ,sensitivity and reduce of time. The Support Vector ‎Machine was flexible and powerful but still not perfectly suited for high resolution ‎images. Classifying such images requires contextual information to be taken into ‎consideration and the SVM could not efficiently learn correct context from training ‎examples. Without including the contextual information obtained from the use of k-‎means. The proposed model can be used to obtain the appropriate classification of ‎satellite to show the layers of the earth covering buildings ,roads, agricultural , desert ‎lands, water, and vehicles, etc. We note that the time does not exceed 32 seconds for ‎the number of images used within our database‎
