A brick is a 3-connected graph such that the graph obtained from it by deleting any two distinct vertices has a perfect matching. The importance of bricks stems from the fact that they are building blocks of the matching decomposition procedure of Kotzig, and Lovász and Plummer. We prove that every brick except for the Petersen graph can be reduced to K4 or the prism by repeatedly applying a ce...

The Olivetti Research Laboratory has developed an experimental system based on intelligent peripherals connected directly to an ATM network. As well as multimedia modules (e.g. audio and video) the system also includes a directly connected RAID-3 storage server called the “Disc Brick”. This paper describes the architecture of the Disc Brick, and discusses some of the hardware and software issue...

Brick industry in India is the second largest brick producer in the world after China. The industry is one of the largest employment generating industries employing millions of people. The present study focuses on the brick industries located in North Karnataka, India, where about 1500 brick kilns are operating employing thousands of workers. The main aim of this study is to investigate the sel...

This paper analyses the effects of addition organic (coffee grounds) and inorganic (fly ash) residues to a clayey soil rich in quartz other silicates used as raw material brick production. To this end mineralogy, texture, durability physical mechanical properties solid bricks fired between 800 1100 °C were studied. The results show that firing temperature increased, phyllosilicate content decre...

Bricks produced from traditional techniques and agricultural clay contribute considerably to the air pollutions in world. Therefore, an urgent need start using environment-friendly alternative material/approach save fertile topsoil conserve a clean environment. This research is aimed produce non-fired bricks incorporating industrial solid waste steel power plants, including Fly ash Ladle Furnac...

The traditional production process of clay bricks involves the extraction significant amounts raw materials and consumes considerable energy, leading to anthropogenic greenhouse gas emissions environmental degradation. Using environmentally friendly in construction industry has become an attractive alternative for mitigating sustainability issues. One such is incorporating waste materials, as w...

Background Air quality monitoring in brick kilns indicates very high concentrations of airborne particulate matter. Air pollution from brick kilns poses an enhanced threat to the environment and to human health. Objective To evaluate airborne particulate matter concentration and health status of brick kiln workers. Method A cross-sectional comparative study was conducted in the Kathmandu valley...

As-fired thick-film resistors have the resistance tolerance within ±20% and this tolerance is increased for smaller components. Therefore the novel trimming methods are necessary for microresistors, especially when they are embedded in LTCC substrate. This paper compares electrical (normalized temperature dependence of resistance, low frequency noise) and stability properties (relative resistan...

Chinese Fuzhuan brick-tea is a unique microbial fermented tea characterized by a period of fungal growth during its manufacturing process. The aim of the present study was to characterize, both physicochemically and microbiologically, traditional industrial production processes of Fuzhuan brick-tea. Fermenting tea samples were collected from the largest manufacturer. Physicochemical analyses sh...
