We present a spatially resolved spectroscopic study of the thermal composite supernova remnant Kes 27 with Chandra. The X-ray spectrum of Kes 27 is characterized by K lines from Mg, Si, S, Ar, and Ca. The X-ray emitting gas is found to be enriched in sulphur and calcium. The broadband and tri-color images show two incomplete shell-like features in the northeastern half and brightness fading wit...

Pada masa kini, tidak diketahui sejauh mana mahkamah Syariah di Malaysia mengendalikan kes-kes jenayah yang membabitkan Orang Kurang Upaya (OKU). Akta dan Enakmen Tatacara Jenayah Negeri-negeri memperincikan tatacara perbicaraan tertentu bagi OKU. Ketiadaan satu khusus menimbulkan kebimbangan tentang penjagaan hak-hak OKU semasa Syariah. Sehubungan dengan itu, kajian ini dijalankan adalah untuk...

This paper describes the effectiveness comparison of noise removal method using visual, semantic and the both features. To automatically generate image dataset from Web, noise image removal should be conducted. Visual and semantic features are available to detect noise images. However, which type of features, and how to combine the two types of feature are unraveled. In this paper, six types of...

A 30 ks Chandra ACIS-I observation of Kes 79 reveals rich spatial structures, including many filaments, three partial shells, a loop and a “protrusion”. Most of them have corresponding radio features. Regardless of the different results from two non-equilibrium ionization (NEI) codes, temperatures of different parts of the remnant are all around 0.7 keV, which is surprisingly constant for a rem...

Poly (lactic acid) (PLA) is biodegradable, melt processable and environmentally benign aliphatic polyester produced from the fermentation of natural renewable resources like corn, sugar and vegetable. The comparative analysis of the effect of time of heatsetting and wet processing from this research showed that PLA exhibited good textile properties for versatile end applications. This research ...

The provision of safely managed sanitation in informal settlements is a challenge, especially in schools that require durable, clean, sex-segregated facilities for a large number of children. In informal settlements in Nairobi, school sanitation facilities demand considerable capital costs, yet are prone to breakage and often unhygienic. The private sector may be able to provide quality facilit...
