Several methods for improving reservoir sweep through conformance control have been used. Methods such as crosslinked polymer technology have alleviated problems associated with reservoir heterogeneity.Other alternatives such as microbial-and surfactant-based methods have been proposed. This paper presents the results of research conducted on polymer-producing bacteria that were isolated and tested at various temperatures and salinities. Coreflooding experiments were conducted to show the effectiveness of microbial treatments, Reduction in effective permeabilities by as much as 90% were achieved due to in situ polymer production. Noninvasive imaging techniques such as magnetic resonance imaging (MRI) and computer-aided tomography (CT) were employed to visualize changes in fluid distribution in porous media. High permeability areas were blocked by biopolymer production, resulting in brine diversion into lower permeability areas.

Our case study explored a Local Resilience Forum's (LRF) civil contingency response to COVID‐19 in the United Kingdom. We undertook 19 semistructured ethnographic longitudinal interviews, between March 25, 2020 and February 17, 2021, with a Director of a Civil Contingencies Unit and a Chief Fire Officer who both played key roles within their LRF. Within these interviews, we focused on their strategic level decision‐making and how their relationship with national government impacted on local processes and outcomes. Using a form of grounded theory, our data describe the chronological evolution of an increasingly effective localized approach toward outbreak control and a growing resilience in dealing with concurrent emergency incidents. However, we also highlight how national government organizations imposed central control on aspects of the response in ways that undermined or misaligned with local preparedness. Thus, during emergencies, central governments can undermine the principle of subsidiarity and damage the ways in which LRFs can help scaffold local resilience. Our work contributes to the theoretical understanding of the social psychological factors that can shape the behaviour of responder agencies during a prolonged crisis. In particular, the implications of our analysis for advancing our conceptual understanding of strategic decision‐making during emergencies are discussed.

AbstractMicrobial enhanced oil recovery (MEOR) technology has advanced, since 1980, from a laboratory-based evaluation of microbial processes, to field applications internationally. In order to adequately support the decline in oil production in certain areas, research on cost-effective technologies such as microbial enhanced oil recovery processes must be focused on both near-term and long-term applications. Many marginal wells are desperately in need of an inexpensive improved oil recovery technology today that can assist producers in order to prevent their abandonment. Microbial enhanced waterflooding technology has also been shown to be an economically feasible technology in the United States. The 5th International Microbial Enhanced Oil Recovery Conference and Related Technology for Solving Environmental Problems was held in September 1995. Various papers were presented from companies and researchers all over the world on field applications using microorganisms. This paper will compile pertinent information and results from those papers to provide an overview of the state of the art of microbial technology with specific emphasis on current field applications.

Background: Food addiction is believed to play a role in the development of obesity. Acute exercise has been associated with reduced cravings for addictive substances. The purpose of this investigation is to determine if food addictive behavior is influenced by physical activity in college-aged students. Methods: 241 college-aged students (18-24 years of age; 55 male, 186 female) were recruited and completed the Yale Food Addiction Scale 2.0 (YFAS) and the International Physical Activity Questionnaire Short Form (IPAQ-S). Results: Only 7.9% of participants were diagnosed with moderate (2.5%) or severe (5.4%) food addiction (FA). BMI was higher in participants with food addiction (No FA=24.1±0.3 FA=26.9±1.9, M±SE, p=0.02); however, no differences were found in vigorous (No FA=1851±251 MET-min/week, FA=1920±799 MET-min/week), moderate (No FA=777+107 MET-min/week, FA=869+409 MET-min/week), or walking (No FA=1262±139 MET-min/week, FA=2051+583 MET-min/week) activity. The distribution of participants with Low, Moderate, and High levels of physical activity was similar between No FA and FA. Participants with High (2.10±0.27 symptoms) levels of physical activity displayed more symptoms of food addictive behavior than participants with Moderate (1.41±0.15 symptoms) and Low (1.06±0.27 symptoms) levels (p=0.03). Conclusions: The results of this investigation suggest that high levels of physical activity may be associated with more symptoms of food addiction.
