Authors: H. Abo Nasria Abbas , Thahab S. M. , H. Saja 
Published: July 2019

Gold(Au), Platium (Pt) and Gold –Coated Platinum (Au@Pt) ultra Fine(UF) nanoparticles (NPs) were preperd by Pulsed Laser Ablation in Liquids method with (Q-switched, 1064 doubled frequency-Nd: YAG). The laser ablation of Au ,Pt metal plates and (Au@Pt) has been performed by immersing these metal plates in two different liquid deionised water (DIW) and ethanol alcohol . (PLAL) process preformed with 100 pulse energy of 700 mJ and liquid depth is 2cm. The nanoparticles of the gold element were coated with platinum(Au@Pt) in two steps. The nanotubes of the gold element were first examined and the platinum metal was then immersed in the liquid from the first step. The formation efficiency of PLAL process was quantified in terms of the absorption spectrum peaks. The absorption spectra ( Pt) in DIW shows a sharp and single peak around 234nm, and (Au@Pt) shows a sharp and single peak for Au at 516nm and for Pt 221nm. The TEM images show that the nanoparticles are rather spherical in shape. While the average size for all the samples was in rang from(2-5)nm. There was an increase in size when using ethanol alcohol. Changing the way of the fluid environment is a simple and flexible way to control the size and strength of Au and Pt and (Au@Pt) colloidal nanoparticles.

Published: July 2019

Chest x-ray medical images are widely used for diagnostic purposes for Cu2ZnSnS4 thin films are prepared by sol gel and spin coating methods. In this study, some physical properties such as structural and optical properties of Cu2ZnSnS4 thin films are investigated. Prepared thin films are annealed at 400°C for 1 h under N2 atmosphere. XRD pattern for the peaks 28.31°, 47.26°, and 56.12° which have indexed plans (112), (220) and (312) confirmed that all Cu2ZnSnS4 thin films prepared have kesterite structure. The results of XRD patterns and UV– Visible spectra demonstrated kesterite phase and a great optical absorption coefficient more than 105­ cm-1 in visible region. The estimation of the band gap which equal Eg ≈ 1.5 eV by dependent at the optical characteristics.

Authors: H. Al-khafaji Kawther , Abd al Jaleel Al-Yasiri Layla 
Published: July 2019

Chest x-ray medical images are widely used for diagnostic purposes for several reasons including it available, attainable and excellent imaging of hard tissues like bones, but there is difficulty in imaging of the soft tissues, moreover the saturated colour of the x-ray image causing intricacy to read it, therefore, turned attention to the colorization process which can be used to transform the grayscale medical images to the colour medical images.
In this paper, a new pseudo-coloring method proposed for colorizing the frontal chest x-ray medical images which are very important for disease detection and recognition. The key idea of this method is applying different and various experimental mathematical equations on the proposed medical sample image, which it belongs to the patient with Hydatid cyst parasite disease in the lung. The counterfeit coloring had intense contribute in enhancing of the visual attractiveness of medical images, the output colored images have a better visual description, it has a possibility to describe hidden information better than a conventional monochromatic image, this is an excellent indicator of the algorithm's suitability for the purpose for which it was formulated.

This paper aims to investigate the dynamic of environmental policy making in the effort of attaining sustainable development. Using Advocacy Coalition Framework (ACF) as a framework of analysis, our study was conducted in the Kendeng environmental conflict, Rembang Regency. Utilised both primary and secondary data on conflict properties from cement industry’s proponents and opponents, researchers obtained vigorous data and evidence through which the ACF may offer a comprehensive explanation on policy process and change. Finding shows that the coalition of actor has a pivotal role to influence value and behaviour among policy actors in the Kendeng environmental conflict. The result of this study fills the lacuna of research which focuses the main discussion on advocacy coalition actor-based policy analysis. It also offers a policy agenda focusing on the belief system actor-based policy analysis in which Government of Indonesia worth to consider in the policy making process.

This study aims to analyze the implementation of the second amendment to tax amnesty policy related to disclosure of voluntary assets at the final rate of corporate taxpayers at West Jakarta Medium Tax Office. This study uses a qualitative descriptive approach. The results showed that the implementation of the second amendment to the tax amnesty policy related to the disclosure of voluntary assets with the final rate in West Jakarta Medium Tax Office according to six factors used by the authors, namely policy size and objectives, resources, communication between organizations, characteristics of implementing agents, dispositions (tendency) of the implementers, social, economic and political environments have been fulfilled. But there are some things that need to be observed, namely the target of PAS-Final policy is not appropriate for corporate taxpayers, which are due to corporate taxpayers more obedient, besides most of the corporate taxpayers have revealed their assets in tax amnesty policies, so the target should be more devoted to individual taxpayers. In addition, the participation of taxpayers to participate in this program is till lacking.

Bungo Regency is one of the autonomous regions in Jambi Province. Bungo Regency is an area that shows rapid development in all fields. These developments have a negative impact which one of these impacts is the rampant drug abuse and covert prostitution. Even though these two factors are the main mediators of the spread of HIV / AIDS. The purpose of this study was to find out about the health service's efforts in preventing the spread of HIV AIDS in Bungo District. The method used in this research is descriptive method with a qualitative approach. In this study the population was the Bungo District Health Office and the Bungo District community as a validity test, the number of samples was 12 informants, consisting of 7 informants from the Health Office and 5 informants from the community. The data collection techniques are through observation, interviews and document review. Processing data is taken from primary data sourced from interviews, secondary data through theoretical analysis sourced from books, reports, and photographs. The results showed that the Health Service's efforts to prevent the spread of HIV / AIDS in Bungo District through various comprehensive measures, including preventive, promotive, curative, and rehabilitative with broad participation and cooperation involving various sectors and non-governmental organizations and communities has been good enough and has progressed but still needs to be improved so that Bungo Regency can be cleared of HIV / AIDS
Endoscopic endonasal anterior clinoidectomy: surgical anatomy, technique nuance, and case series
Authors: Xiao Limin , Xie Shenhao , Tang Bin , Hu Jialing , Hong Tao 
Published: July 2019

Advances in endoscopic technique allow for resection of the anterior clinoid process (ACP) via an endoscopic endonasal approach. The authors discuss the endoscopic endonasal anterior clinoidectomy (EEAC) and demonstrate the relevant surgical anatomy and technical nuances. The approach was simulated in 6 cadaveric heads. From a technical point of view, the lateral optic carotid recess was used as the landmark in the proposed technique. The superomedial, superolateral, and inferior vertices of this recess are the main operative points. The EEAC approach was achieved by disconnecting the ACP tip from the base by drilling the 3 vertices. The proposed approach was successfully performed in all cadaveric specimens. Then, in a case series involving 6 patients in whom the EEAC approach was used, there were no vascular injuries; 2 patients had postoperative oculomotor nerve palsy, which improved in one and resolved in the other by 1 month.The EEAC approach for tumors and vascular lesions in the parasellar region is technically feasible. The surgical corridor is increased by ACP resection, although to a lesser extent than the transcranial anterior clinoidectomy. Based on the authors’ initial anatomical and surgical results, resection of the ACP via the endonasal endoscopic approach is a novel technique worth exploring in suitable cases.
