    The use of biomaterials in orthopaedics for joint replacement, fracture healing and bone regeneration is a rapidly expanding field. Infection of these biomaterials is a major healthcare burden, leading to significant morbidity and mortality. Furthermore, the cost to healthcare systems is increasing dramatically. With advances in implant design and production, research has predominately focussed on osseointegration; however, modification of implant material, surface topography and chemistry can also provide antibacterial activity. With the increasing burden of infection, it is vitally important that we consider the bacterial interaction with the biomaterial and the host when designing and manufacturing future implants. During this review, we will elucidate the interaction between patient, biomaterial surface and bacteria. We aim to review current and developing surface modifications with a view towards antibacterial orthopaedic implants for clinical applications

    الهدف من هذا البحث هو تقديم ودراسة فئة جديدة من الفضاءات التبولوجية والتي اسميناها بالفضاءات المنتظمة من النمط  Sw*-  باستخدام مفهوم المجموعة المنتظمة - Sw وبعض خصائصها والتي قدمت من قبلL. S.  Abddullah, A. B. Khalaf [1]  في عام 2009 ، حيث ان هذا الفضاء هو فضاء جزئي من الفضاء المنتظم   .[2], [3] S*-اي ان الفضاء المنتظم - Sw*  تكون اقوى من الفضاء المنتظم  .S*- تمت دراسة العديد من خصائص هذا الفضاء وعلاقة الفضاء المنتظم - Sw* مع الفضاءات الاخرى كالفضاءات المتراصة - Sw ،غير متصل للغاية ، المنتظمة ، شبه المنتظمة ، Sw-T2  و يوريسون. علاوة على ذلك تم دراسة العديد من الصفات للفضاء المنتظم Sw*-  مع بعض الدوال  كالدوال المستمرة ، المستمرة  بقوة ، الدوال المفتوحة، الدوال المفتوحة المغلقة والدوال المفتوحة إلى حد ما. بالإضافة إلى ذلك ، قمنا بالتحقق من ان الفضاء المنتظم - Sw* لها خاصية تبولوجية ، في حين أنها لا تمتلك الخاصية الوراثية ، الا باضافة شروط معينة  كأن يكون  الفضاء الجزئي مفتوح أو إذا كان الفضاء  الجزئي من الفضاء المنتظم -*Sw  دون الحد الأقصى  مفتوح قبلا وعندها يصبح الفضاء الجزئي فضاء منتظم من النمط Sw*-  .The purpose of this paper is to present and investigate a new class of topological spaces known as Sw*-regular spaces, by utilizing the concept of Sw-regular sets and some of its properties. which is introduced in 2009 by L. S. Abddullah and A. B. Khalaf [1], the new class is properly contained in S*- regular space [2], [3], means that Sw*- regular spaces is a stronger form to the space S*- regular. Several characterizations, properties and relationships of Sw*- regular space with other spaces such as, Sw-compact, extremally disconnected, regular, semi-regular, Sw-T2 and Urysohn spaces has been studied. Furthermore, several properties of Sw*- regular spaces with some functions such as, continuous, strongly continuous, open, clopen and Somewhat open functions are also explored. In addition we investigate that Sw*- regular space has a topological property, while it has not a hereditary property, only by adding certain conditions such as, a subspace is open or, if the subspace of an Sw*-regular submaximal space is  preopen, then it becomes an Sw*- regular

    The politics of local government environmental evaluations: Assessing bureaucracy in post-Reformasi Indonesia

    Get PDF
    This article argues that bureaucracy plays politics in Indonesia, not only during the electoral periods, but also in public service. Using the case of environmental evaluation in local government, where natural resources comprise most of the local economy, this article discusses the politics of bureaucracy in undergoing daily governing processes. The environment and natural resource businesses are two opposing fields. Environmental evaluation becomes a contentious area and is usually highly political. This article identifies the bureaucracy’s politicisation in environmental evaluation as occuring in at least in two forms—in measurement and in project implementation. In terms of measurement, bureaucracy tends to use minimum standards, while in project implementation, there are some occasions where bureaucracy tends to sub-contract the work to the third party, usually NGOs, especially in relations to sensitive issues, so that it is politically safer for them, once the result is not as pleasing as expected. This article uses some cases in Central Kalimantan, East Kalimantan, Central Java, and Bangka Belitung, and applied case study as research approach
