The effect of artificial pozzolan (waste brick) on the physico-chemical properties of cement manufactured was investigated. The waste brick is generated by the manufacture of bricks. It was used in the proportions of 0%, 5%, 10%, 15% and 20% by mass of cement to study its effect on the physico-chemical properties of cement incorporating artificial pozzolan. The physicochemical properties of cem...

achaemenid glazed bricks of archaeological excavation of tall-e-ajori in persepolis city were studied by multiple instrumental analysis methods  such as xrf, xrd, sem-eds, icp and optical microscopy to identify the compositional features of glaze and brick body. glaze samples are apparently white and yellow  and this phenomenon are caused by the deterioration processes in burial environment, he...

In this paper, a mobile scanning system for real-time under-vehicle inspection is presented, which is founded on a “Brick” architecture. In this “Brick” architecture, the inspection system is basically decomposed into bricks of three kinds: sensing, mobility, and computing. These bricks are physically and logically independent and communicate with each other by wireless communication. Each bric...

Creating and establishing a successful innovation is challenging and many attempts fail. Despite of the complex nature of the phenomenon, previous literature often tends to limit its focus on either to the technical elements or human elements related to an innovation. Current research-in-progress paper aims to avoid this ‘either-or’ thinking and rather examine the roles, impact and mutual inter...

BACKGROUND Brick manufacturing industry is one of the oldest and fast-growing industries in India that employs a large section of people. Brick kiln workers are occupationally exposed to air pollutants. Nonetheless, only a few studies have so far been conducted on their respiratory health. OBJECTIVE To investigate the extent of respiratory impairment in brick kiln workers and to correlate it ...

BACKGROUND Numerous malaria epidemics have occurred in western Kenya, with increasing frequency over the past 20 years. A variety of hypotheses on the etiology of these epidemics have been put forth, with different implications for surveillance and control. We investigated the ecological and socioeconomic factors promoting highland malaria vectors in the dry season after the 2002 epidemic. ME...

In 1987, Lovv asz conjectured that every brick G diierent from K 4 , C 6 , and the Petersen graph has an edge e such that G e is a matching covered graph with exactly one brick. Lovv asz and Vempala announced a proof of this conjecture in 1994. Their paper is under preparation. We present here an independent proof of their theorem. We shall in fact prove that if G is any brick diierent from K 4...

This study aims to determine the major elements of Portland cement type I and II (CEMI and CEMII) in a cement factory in north Tunisia and which metal elements are introduced into the production process. We determine also the metal input rate and their distribution at the entrance and exit of the process. The major elements were analyzed and the trace elements (Arsenic, barium, lead, mercur...
