ISO 13779-1:2008 specifies requirements for ceramic hydroxyapatite intended for use as surgical implants. It applies to hydroxyapatite blocks. ISO 13779-1:2008 does not apply to hydroxyapatite coatings, hydroxyapatite powder or nanoparticle-type and calcium phosphate ceramics which are not mainly composed of crystalline hydroxyapatite.MS ISO 13779-

This Malaysian Standard specifies test methods for measurement of the adhesion strength of hydroxyapatite coatings intended for use on components of surgical implants.

This Malaysian Standard describes the method for detecting apatite formed on a surface of a material in simulated body fluid (SBF).

The realties we know as organizations come to exist through conversations. For years such conversations are shaped by the mainstream Cartesian worldview and Newtonian mechanics. As cracks on the said worldview and fissures on the above mechanics become bigger and wider, the need to look at other ways of seeing and producing a more ‘living convers

By controlling the cavity loss of the modes using a variable optical attenuator, specific intensities of distributed modes can be fed back into the erbiumdoped fiber to produce signals without mode competition, thus resulting in stable lasing as a means to overcome mode competition in a homogenous gain medium. Two lasing signals were obtained with

In this paper, we propose and demonstrate a dual wavelength fibre laser (DWFL) based on the use of an inhomogeneously-broadened semiconductor optical amplifier (SOA) gain medium as well as two arrayed waveguide gratings (AWGs) together with two optical channel selectors (OCSs) and a broadband fibre Bragg grating (FBG) to generate dual wavelength ou

The present work reports a novel method for preparation of porous alumina using egg yolk both as consolidator and foaming agent. Suspensions with an alumina to yolk ratio of 1 in weight were prepared by stirring for 3 h and the resulting slip was poured into cylindrical shaped moulds followed by foaming and consolidation by drying at temperatures o

Kosovo, sebuah wilayah kecil di Balkan, mengumumkan kemerdekaannya dari Serbia pada bulan Januari 2008. Hal itu memicu banyak pihak yang sekian lama berazam mahu membebaskan diri daripada kekuasaan pemerintahan pusat atas pelbagai sebab. Dahulu, ketika Timur Timor (kini Timor-Leste) berjaya melepaskan diri daripada belenggu Indonesia, gelora untuk

Isu agama dan bangsa sejak sekian lama menjadi rabuk api benua India. Pada tahun 1947, British berundur dari benua tersebut setelah beratus-ratus tahun menjajahnya. Benua yang dikenali sebagai manikam empayar terbesar dunia itu terpecah dua apabila sebahagian besar rakyat India yang beragama Islam membentuk sebuah negara baharu, Pakistan. Yang satu

Singapura ialah sebuah negara pulau kecil di Asia Tenggara. Keluasan tanah negara itu sebelum tahun 1960-an tidak lebih daripada 581.5 kilometer persegi. Oleh sebab bilangan penduduk yang meningkat selain usaha pembangunan yang rancak, Singapura memerlukan kawasan tanah yang lebih luas. Salah satu jalan meluaskan kawasan adalah dengan kerja penamba
