This paper introduces the use of a scanning electron microscope (SEM) to evaluate the insulation property of insulators under electron bombardment. An SEM may be used not only to observe a surface image but also to provide a fine electron beam for charging an insulator surface simultaneously. The distribution of electric field created by the surfac

High purity MgO is a common ceramic material used as a protecting layer in an alternating current plasma display panel (AC-PDP). In this work, pure MgO was added by CaO for a better protecting layer. The effect of CaO addition was discussed according to the changes in the microstructure, mechanical strength and the ability of the sample to withstan

Field-induced oxidation has become a promising process that is capable of directly producing high-resolution surface oxide patterns on variety materials. In this report, a low temperature operation of an atomic force microscope (AFM) was used to condense ambient humidity to perform a thin frozen water layer covering a silicon wafer surface. A scann

PENGENALAN Seperti yang kita sedia maklum, kerajaan Malaysia amat menghargai peranan dan sumbangan belia di dalam arus pembangunan negara. Sesungguhnya golongan belia merupakan aset yang terpenting kepada Negara dan mereka inilah yang akan terus menerajui pembangunan negara di masa yang akan datang. Justeru itu, ia amat bersesuaian dengan maksud pe

A surface breakdown (flashover) might occur on the surface of an insulator when it was bombarded by electron beam until exceeding a critical value. The strength of SiO2 added MgO to withstand flashover treeing appearance was evaluated by bombarding the samples by 25 keV electron beam generated by a scanning electron microscope. There was a signific

This chapter attempts to provide a condensed account of the philosophical and sociological thought of the twentieth-century eminent Algerian thinker Malik Bennabi (1905–73). It focuses on his views pertaining to religion, society, and culture. The present chapter consists of three main sections that are prefaced with a short biographical sketch o

OBJECTIVE: To assess ultrasonographically (US) guided needle aspiration of breast abscesses as an alternative to surgical incision and drainage. METHODS: In our prospective study, 30 patients with 31 breast abscesses (one patient had bilateral breast abscess) underwent percutaneous breast abscess drainage under US guidance with local anaesthesia an

We consider a nearest-neighbor Potts model, with countable spin values Φ = {0, 1, . . .}, and nonzero external field, on a Cayley tree of order k (with k + 1 neighbors). We study translation-invariant ‘splitting’ Gibbs measures. The problem is reduced to the description of the solutions of some infinite system of equations. We give full descri

This paper presents an approach to establish models for tool life in end milling of titanium alloy Ti–6Al– 4V using uncoated carbide inserts under dry conditions. Small central composite design (CCD) was employed in developing the tool life model in relation to primary cutting parameters such as cutting speed, axial depth of cut and feed. Flank

A preliminary model is introduced in this paper whereby data and its associated security properties are treated as a single atomic unit of information in a hardware-only context. Security-tagged data allows each datum to be properly manipulated with a predictable assurance. This paper addresses the data modeling, process modeling and network modeli
