Most models of consumer purchase process that are used in operations focus on purchases from a single channel, typically the offline brick-and-mortar store [3]. However, there has been a proliferation of multiple retail channels, such as online and mobile. This proliferation has created the need for operational decisions to model consumer switching between different channels during the purchase...

Abstract The increasing demand in the construction industry has led to a vast development recent years. However, impacts of this are arising such as amount waste. majority solid waste is dumped landfills despite its recyclable potential. Therefore, there should be more viable solution answer issue. objective literature review obtain information each kind that most recycled with methods. based o...

Concrete is made of coarse aggregate, fine water, cement in specific mix proportion. Coarse aggregates occupy the largest volume concrete which one most widely used construction material as per industry surveys. In order to evaluate feasibility using brick wastes aggregate producing concrete, this study was undertaken. Several million tons solid waste are produced each year due and demolition a...

The recovery of municipal solid waste incineration (MSWI) fly ash is currently considered to be the most viable solution for its management. However, in developing resource technologies, it crucial consider overall environmental impact. This study employed a life-cycle assessment (LCA) compare environmentally friendly red bricks partially utilizing MSWI as raw material with conventional bricks....

We prove that every minimal brick on n vertices has at least n/9 vertices of degree at most 4.

BACKGROUND Medical establishment such as hospitals and research institutes generate sizable amount of hazardous waste. Health care workers, patients are at risk of acquiring infection from sharps and contamination of environment with multiple drug resistant microorganisms if wastes are not properly managed. OBJECTIVES To characterize types and evaluate waste disposal techniques employed in th...

Abstract The simulation and corrosion conduction of anti-acid brick in high temperature particle abrasion circumstances were tested with scanning electron microscopic, mechanical compression, X-ray diffraction. results showed the strength degradation rates Anti-acid 7.0% 17.8% different high-temperature acid conditions. water vapor environment permeated into after eroding crystal structure surf...

In the cellulose industry the Kraft process is widely used to produce cellulose. This process generates huge volumes of inorganic solid wastes, including the grits waste. In Brazil, the final disposal of this solid waste is of high economical and environmental interest. The present work assesses the influence of the addition of grits waste on the densification behavior of soil-cement bricks. Th...

background: the aim of this study was to measure137cs levels in soil and brick samples to set the baseline data and an indicator of fallout radioactivity for this part of the world. this study will help to probe, if there is any health threat posed by 137cs exposure to the residents of the area. materials and methods: twenty five samples of soil and 6 samples of bricks were collected from diffe...
