Reintegration in northern Iraq: the time is now for Europe to act

To prepare the ground for the safe return and reintegration of dispersed population groups, it is necessary to solve the conflict between the government of Iraq and the government of the Kurdistan Region of Iraq about Constitutional Article 140. The ministries of foreign affairs of the European Union member states should intensify the political dialogue with both sides to find a durable agreement and, in parallel, offer advice on reforms to increase civilian oversight of the security forces. As Iraq is no longer considered an emergency country, donors, including the German Federal Ministry for Economic Cooperation and Development (BMZ), can gradually shift the emphasis of bilateral development aid towards the export of expertise. German advice in e-government and administrative set-up can contribute to reducing corruption and developing the basis for decentralisation (implementing Law 21). Effective and good governance is at the root to legally clarify property and land disputes many returning Iraqis are struggling with. A regular supply of basic services and the provision of infrastructure are prerequisites for the return and reintegration of displaced people. Taking care of the needs of internally displaced persons (IDPs) can be closely linked with livelihood support and compensation in the framework of long-term reconciliation and peacebuilding measures adjusted to varying local contexts. Together with European donors, the BMZ should engage in bilateral dialogues with the government of Iraq to facilitate the access of NGOs experienced in setting up these processes. German and European partners in development cooperation should support the economic reform envisaged by the government of Iraq. Given the long-standing dominance of the public sector, private sector development should go hand in hand with a gradual re-orientation of the public sector towards providing infrastructure and services for businesses and households. This dual focus will benefit returnees and receiving communities in the long run

PREPARATION AND EVALUATION OF METRONIDAZOLE SUSTAINED RELEASE FLOATING TABLETS

Objective: The objective of the present study is the preparation of metronidazole (MZ) floating tablets that are designed to retain in the stomach for a long time for better eradication of Helicobacter Pylori (H. pylori), a main cause of peptic ulcer disease. Methods: Synthetic and natural polymers were studied for their floating potential in the presence of sodium bicarbonate, namely: hydroxypropyl methylcellulose (HPMC), carbopol 974P, sodium alginate{low and medium viscosity (LV & MV) grades}, locust gum and guar gum. Hardness, floating ability, release profiles and kinetics as well as DSC / FT-IR were studied. Results: Results of both DSC and FT-IR spectroscopy revealed that there was no interaction between the drug and any of the proposed polymers. Carbopol 974P based tablets showed an unacceptable floating lag time (2 h) and did not maintain good tablet integrity. All other formulas were able to float after few seconds and showed buoyancy for more than 24 h. Meanwhile, sustained profiles of MZ release were obtained. After 6 h the amount of MZ released were: 75.11 %, 61.26 %, 54.56 %, 54.25 % and 43.42 % from sodium alginate-LV, HPMC-K4M, guar gum, locust gum and sodium alginate-MV based tablets, respectively. Kinetically, among the 5 assessed models, the release pattern of MZ from the tablets fitted best to Zero order and Hixson & Crowell Cube-Root models. Conclusion: These stomach targeted dosage forms could maintain the minimum inhibitory concentration for sufficient time to allow for local eradication and thereby achieve better efficiency of therapy with improved patient compliance, reduced costs and minimized side effects caused by immediate release dosage forms

INFLUENCE OF ORGANIC MANURE, BIOFERTILIZER AND/OR SOME VITAMIN TREATMENTS ON: A. VEGETATIVE GROWTH AND FLOWERING ASPECTS OF GLADIOLUS GRANDIFLORUS VAR. GOLD FIELD PLANTS

A field experiment was carried out during the two successive seasons of 2016/2017 and 2017/2018. The aim of this study was to investigate the effect of farmyard manure (FYM) at four levels (0, 10, 15 and 20 m3/fed) in combination with Minia Azotein (M.A.) at 50 ml/plant and/or some vitamins (E and C) each at 50 ppm, in addition to the control on vegetative growth and flowering of Gladiolus grandiflorus var. Gold Field plants. Results showed that leaf length (cm), number of leaves/plant, leaves dry weight/plant (g), length of spike (cm), spike diameter (mm), spike fresh weight (g), number of florets/spike, lower floret diameter (cm) and lower floret fresh weight (g) were gradually increased by increasing the levels of farmyard manure with significant differences were detected between successive treatments. Also, Minia Azotein (M.A.) and/or some vitamins (E and C) treatments significantly increased all vegetative growth and flowering parameters in comparison with the control. Minia Azotein (M.A.) plus vitamins E and vitamin C were more effective in this concern. It was found also that the use of FYM (20 m3/fed) in combination with Minia Azotein (M.A.) plus vit. E and vit. C followed by 20 m3/fed FYM with M.A. + vit. C then 15 m3/fed FYM with M.A. + vit. E + vit. C noticeably improved the different vegetative growth and flowering parameters of gladiolus plants

Cyber Physical Energy Systems Modules for Power Sharing Controllers in Inverter Based Microgrids

The Microgrids (MGs) are an effective way to deal with the smart grid challenges, including service continuity in the event of a grid interruption, and renewable energy integration. The MGs are compounded by multiple distributed generators (DGs), and the main control goals are load demand sharing and voltage and frequency stability. Important research has been reported to cope with the implementation challenges of the MGs including the power sharing control problem, where the use of cybernetic components such as virtual components, and communication systems is a common characteristic. The use of these cybernetic components to control complex physical systems generates new modeling challenges in order to achieve an adequate balance between complexity and accuracy in the MG model. The standardization problem of the cyber-physical MG models is addressed in this work, using a cyber-physical energy systems (CPES) modeling methodology to build integrated modules, and define the communication architectures that each power sharing control strategy requires in an AC-MG. Based on these modules, the control designer can identify the signals and components that eventually require a time delay analysis, communication requirements evaluation, and cyber-attacks’ prevention strategies. Similarly, the modules of each strategy allow for analyzing the potential advantages and drawbacks of each power sharing control technique from a cyber physical perspective

RESPONSE OF JOJOBA (SIMMONDSIA CHINENSIS, LINK) PLANTS TO COMPOST AND SOME STIMULATING SUBSTANCES TREATMENTS

This work was done during the two experimental seasons of 2020 and 2021 at the farm of Faculty of Agriculture, Minia University, Egypt to study the reaction of jojoba (Simmondsia chinensis, Link) plants to compost (0.0, 500, 1000 and 1500 g/container) and some stimulating substances (control, vitamin E at 100 ppm, active yeast at 10 g/l and garlic extract at 10%) treatments. Data revealed that increasing the level of compost led to a significantly increased in plant height, main stem thickness, number of branches/plant and aerial parts and root weights (fresh or dry) compared with control. While sprayed plants with all stimulating substances significantly enhanced all previous characters compared with the control. It can be concluded that the high level of compost (1500 g/container) plus yeast at 10 g/l or garlic extract at 10% led to the greatest growth parameters of jojoba plan

This work was performed in the two experimental seasons of 2020 and 2021 at the farm of the Faculty of Agriculture, Minia University, Egypt to study the effect of compost (0.0, 500, 1000 and 1500 g/container) and some stimulating substances (control, vitamin E at 100 ppm, bread yeast at 10 g/l and garlic extract at 10%) on leaves and some chemical composition of jojoba (Simmondsia chinensis, Link) plants. Data showed that all used levels of compost pronounced increased leaves traits (number, leaf area, leaves weights (fresh or dry) in addition to chemical composition (pigments content, NPK percentages and protein) compared with the control. The 1500 g compost/container was more active than other treatments. Also, sprayed plants with vitamin E, active yeast and garlic extract significantly improved all previous parameters compared with the control. In general, the treatment of active yeast was superior, followed by garlic extract than vitamin E treatment. Therefore, the best interaction treatment was recorded with the high level of compost (1500 g/container) plus bread active yeast (10 g/l) or garlic extract (10 %)

Machine Learning Techniques for Credit Card Fraud Detection

The term “fraud”, it always concerned about credit card fraud in our minds. And after the significant increase in the transactions of credit card, the fraud of credit card increased extremely in last years. So the fraud detection should include surveillance of the spending attitude for the person/customer to the determination, avoidance, and detection of unwanted behavior. Because the credit card is the most payment predominant way for the online and regular purchasing, the credit card fraud raises highly. The Fraud detection is not only concerned with capturing of the fraudulent practices, but also, discover it as fast as they can, because the fraud costs millions of dollar business loss and it is rising over time, and that affects greatly the worldwide economy. . In this paper we introduce 14 different techniques of how data mining techniques can be successfully combined to obtain a high fraud coverage with a high or low false rate, the Advantage and The Disadvantages of every technique, and The Data Sets used in the researches by researcher

EFFECT OF COMPOST AND SOME NATURAL STIMULANT TREATMENTS ON: I. VEGETATIVE GROWTH AND FLOWERING ASPECTS OF (GLADIOLUS GRANDIFLORUS CV. PETER PEARS) PLANTS

Two field experiments were carried out during the two successive seasons of 2014/2015 and 2015/2016 at the Nursery and the Laboratory of Ornamental plants, Faculty of Agriculture, Minia University. The aim of this study was to figure out the effect of organic fertilization and natural stimulants, as well as, their interaction on vegetative growth, flowering aspects of Gladiolus grandiflorus cv. Peter Pears plants. Results showed that vegetative growth (leaf length, number of leaves/plant and dry weight of leaves/plant) and flowering aspects (length of spike, number of florets/spike and lower floret diameter) were gradually increased by increasing the level of compost fertilizer. All natural stimulant treatments significantly increased all vegetative growth characters and flowering parameters in comparison with the control. Seaweeds extract at 3 cm3/l or active dry yeast at 5 g/l seemed to be more effective than other treatments in this concern. The use of high level of compost (7.5 ton/fed) in combination with seaweeds extract at 3 cm3/l or active dry yeast at 5 g/l noticeably improved the different vegetative growth characters and flowering parameters of gladiolus
