The objectives of this work are: (a) to present a new system for building heating which is based on underground energy storage, (b) develop mathematical model the system, and (c) optimise performance system. includes Photovoltaic Thermal Hybrid Solar Panels (PVT) panels with cooling, an evacuated solar collector water-to-water heat pump. Additionally, storage tanks, placed underground, are used...

J.E. Braun, Ph. D., P.E. Purdue University This paper describes the development and validation of an improved mechanistic model for predicting the thermal performance of an area constrained ice storage system. Experimental data was obtained from a fully instrumented thermal storage test cell located within the Herrick Laboratories, Purdue University. Results for both charging and discharging cy...

Ground cylindrical steel fluid storage tanks are widely used in different industries. Regarding the significance of these structures, it is important to establish their proper performance in earthquakes by evaluating their seismic performance. The present study examines the seismic behavior of an unanchored fluid storage system via ABAQUS after validation using an experimental model. Next, the ...

With the development of minimally invasive tooth extraction, the incidence rate of iatrogenic cross infection is increasing. Hence, the present study was carried out in order to a) develop a new, feasible disinfection strategy to be used in high-speed turbine and 3-function sprayer water systems and b) assess the clinical significance of newly developed disinfection strategy. A total of 178 pat...

Most of the Oil Pumping Units (OPU) are manually monitored. This existing oil-pumping systems use a high power-consuming process, is incapable of OPU’s structural health monitoring. In this paper, a sensor network based intelligent control is proposed for power economy and efficient oil well health monitoring. The condition of the oil storage tanks can be monitored using sensors like level sens...

Reclaimed wastewater for irrigation is an opportunity for recovery of this natural resource. In this study, microbial risk from the use of treated wastewater for irrigation of recreational parks in the city of Chihuahua, evaluating the effect of distribution distance, season, and presence of storage tanks, was analyzed. Escherichia coli, Salmonella, and multidrug-resistant bacteria were recover...

Oman depends on recycling treated wastewater as a solution to overcome the limited water supply. However, the risk of reusing recycled sewage water in the environment and public health is a major concern. Tertiary sewage treated effluent (TSE) was evaluated microbiologically from three sewage treatment plants (STPs). Mainly, all TSE from the three plants contained coliform and Escherichia coli....

Samples obtained from plumbing systems of hospitals, nonhospital institutions and homes were cultured for Legionella spp. by plating the samples directly on a selective medium. Swab samples were taken from the inner surfaces of faucet assemblies (aerators, spouts, and valve seats), showerheads, and shower pipes. Water and sediment were collected from the bottom of hot-water tanks. Legionella pn...

INTRODUCTION Protect the oil wells to increase their longevity is now one of the major oil-producing countries is difficult. Each year, an extraordinary global budget for research on EOR and MEOR (enhanced oil recovery methods) is allocated. In addition, the owners of these vessels extraordinary efforts to exploit new, lower cost, and highly efficient techniques. A new and promising way to incr...

Rainwater itself is free from pathogens and contamination levels of stored rainwater are generally low if tanks are well protected with covers or lids but obvious sources of contamination of the rainwater runoff can originate from faecal matter deposited by birds, frogs, possums, rodents, and dead animals and insects, either on the roofs or in the gutters, or in the water tank itself. A number ...
