There is a need to enhance the effectiveness and reach of complex health promotion initiatives by providing opportunities for diverse health promotion practitioners and others to interact in online settings. This paper reviews the existing literature on how to take health promotion communities and networks into online settings. A scoping review of relevant bodies of literature and empirical evidence was undertaken to provide an interpretive synthesis of existing knowledge on the topic. Sixteen studies were identified between 1986 and 2007. Relatively little research has been conducted on the process of taking existing offl ine communities and networks into online settings. However, more research has focused on offline (i.e. not mediated via computer networks); ‘virtual’ (purely online with no offl ine interpersonal contact); and ‘multiplex’ communities (i.e. those that interact across both online and offl ine settings). Results are summarised under three themes: characteristics of communities in online and offl ine settings; issues in moving offl ine communities online, and designing online communities to match community needs. Existing health promotion initiatives can benefit from online platforms that promote community building and knowledge sharing. Online ehealth promotion settings and communities can successfully integrate with existing offl ine settings and communities to form ‘multiplex’ communities (i.e. communities that operate fl uently across both online and offl ine settings).

This document summarizes the key points from Dr. Jenine Beekhuyzen's doctoral research on unauthorized file sharing communities online. She conducted an ethnographic study of an underground file sharing community called "Roswell" over 120 days, including interviews and covert observation. Her findings showed that the community had strong social norms for participation and contributed content in a meritocratic way. She found that members' motivations for file sharing included issues of cost, convenience, and choice compared to legitimate options. Her research provided insights into these underground communities and implications for the design of legitimate online music systems.

the effect of rheological parameters on the flow diversion, and also the effect of initial permeability, shear rate, and temperature on the acidization curve, have been investigated in the thesis.
Matrix acidizing refers to one of two stimulation processes in which acid is injected into the well penetrating the rock pores at pressures below fracture pressure.
Imaging the distribution of porosity, permeability, and fluid phases is important to understanding single and multiphase flow characteristics of porous media.
This document presents a developed model for predicting the performance of carbonate matrix acidizing. It begins with an introduction and literature review on experimental and mathematical modeling studies of matrix acidizing. It then describes the development of a continuum model using Darcy's law to model acid transport and reaction in porous media. The model accounts for non-Newtonian rheology of in-situ crosslinked acids. Results are presented on wormhole formation and the effects of injection rate, permeability, and permeability contrast using the developed model. Conclusions drawn include how rheology parameters influence acid diversion. Recommendations include extending the model to include polymer filtration effects.
1) Sandstone acidizing involves using acid mixtures to dissolve formation damage and improve permeability in sandstone formations near the wellbore. It aims to remove clay and fine silica particles plugging permeability.
2) The first sandstone acidizing treatment used a mixture of HCl and HF in 1933, but resulted in sand production. Improved practices using tapered HF treatments with HCl preflushes and overflushes were developed in the 1960s.
3) Successful sandstone acidizing requires determining whether removable skin is present, selecting the right fluids and volumes, establishing additive programs, properly placing treatments, executing treatments with quality control, and evaluating results.
The flow of fluids through these pores is often restricted because of permeability damage in the near-wellbore (NWB) formation. During matrix acidizing, the acid treatment is injected at matrix pressure and staying below formation fracture pressure.
Matrix acidizing of carbonates and silicates are worlds apart.
This document discusses nested designs in experiments. It defines nested designs as those where levels of one factor (B) are nested within or occur only with levels of another factor (A). An example is given of a forest genetics study measuring tree seedling height where seeds come from trees nested within different forests. The document outlines the linear model, effects, null hypotheses, partitioning variation, nested ANOVA table, testing hypotheses, and computations for a nested design.
1) The document presents numerical and analytical models for simulating natural gas production from methane hydrate dissociation.
2) It describes the problem of hydrate dissociation in wells, which can cause wellbore collapse if not controlled. Various techniques to avoid this such as cooling drilling fluid or increasing mud weight are also discussed.
3) The analytical model assumes hydrate dissociation occurs immediately when pressure drops below threshold and follows first-order kinetics. The numerical model sets up governing equations to simulate two-phase flow and permeability changes during dissociation.

The document discusses a polymer flooding project in the Bohai Bay offshore oilfield in China. It summarizes that the project used a hydrophobically associating water-soluble polymer (HAWP) for polymer flooding due to challenges of high salinity water and highly viscous oil. The HAWP demonstrated good viscosification, solubility even at high salinity, resistance to mechanical degradation, long-term thermal stability, and could be treated from produced fluids. The polymer flooding project using HAWP achieved a decrease in water cut and increase in oil production for the wells.
The document discusses an alkaline-surfactant-polymer (ASP) flood at an oil reservoir. Surfactants reduce oil-water tension to mobilize trapped oil while alkalis make the reservoir more water-wet. Initial ASP injection targeted 34% of the pore volume across 45 production and 18 injection wells. Major challenges included silicate scale buildup, which decreased injectivity and production over time. Later phases increased polymer injection and used improved scale inhibitors to partially address production declines, but ultimate recovery estimates were still reduced.
