The public–private divide in household behavior: How far into home can energy guidance reach?

Environmental problems in the energy system often originate from everyday activities and choices. Everyday activities in the home are part of the private sphere that can be contested in relation to energy policies. This article discusses the public–private divide in energy policies and how Swedish municipal energy consultants understand the divide. By analyzing the actions of energy consultants and their efforts to influence households, as well as how households perceive this guidance, I will discuss the public–private discourse in relation to energy policy and how this discourse can be a restriction for the energy consultants to reach their full potential.

Emergency Management in the Swedish Electricity Grid from a Household Perspective

This article focuses on households' action space and perceived responsibilities during power outages, and on how municipalities and grid companies understand their own and the households' responsibilities and action space. Results from a case study in the county of Östergötland showed that household responsibilities in terms of preparedness for outages were unclear to the actors. Both municipalities and grid companies expected households to be somewhat prepared. Households, however, believed that they were not responsible for being prepared for power outages, even though they need to be prepared to survive. Often the preparedness concerns material factors, such as investment in auxiliary generating capacity for use in case of outages. How the households perceive outages is important for their capacity to handle and feel comfortable in such situations.     

The novel usage of spectroscopic ellipsometry for the development of amorphous Si solar cells

We present the novel use of spectroscopic ellipsometry (SE) for the development of a-Si:H solar cell. SE is a very fast and useful tool to measure various optical properties of thin film. In the case of a-Si:H thin film analysis, generally, SE is used to estimate the film thickness, roughness, void fraction, optical constants such as (n,k), and so forth. In this study, optical parameters from SE measurements were analyzed with relation to structural and electrical properties of a-Si:H thin film for solar cell. By analyzing IR absorption spectra and conductivity measurements, it was affirmed that <ε₂> and parameter A by Tauc-Lorentz model fitting of SE data are representative parameters qualifying a-Si:H thin film, and that they have close relationships with FF and light induced degradation property of solar cells. Based on the analysis, solar cells that have i-layers with various E_g were optimized. By this research, easier and faster methodology to develop a-Si:H thin film for thin film Si solar cells using SE measurements was established.     

Fire‐retardant poly(ethylene terephthalate) by combination of expandable graphite and layered clays for plastics and textiles

Expandable graphite (EG) and polyethylene terephthalate (PET) were melt blended to develop a new nanocomposite intumescent flame retardant in which the effect of combination of EG with nanoclays would be exploited with sodium and organo‐modified montmorillonites, namely Cloisite^®Na, Cloisite^®10A and Cloisite^®30B. X‐ray diffraction analysis coupled to transmission electron microscopy and rheology shows that PET–EG–clay compounds are characterized by an exfoliated and/or intercalated morphology as a function of the type of clay. Thermal stability of composites is enhanced in nitrogen and air by filler adding as compared with neat PET, while combustion rate is decreased both in the bulk material and in textiles made of fibers spun from the compound.

Fluorescent dye labeled bacteriophages--a new tracer for the investigation of viral transport in porous media: 1. Introduction and characterization

A new method for the study of pathogen transport in porous media is presented. The method is based on conjugation of fluorescent dyes to target bacteriophages and application of the modified bacteriophages for tracer studies. We demonstrate that the relevant transport determining properties of Rhodamine and several fluorescein-labeled phages are practically identical to those of the native bacteriophages. The advantages of the proposed method relative to direct enumeration of bacteriophages by plaque forming unit method, turbidity, fluorescent microspheres, and other alternative tracers are discussed. Notable advantages include simple quantitation by optical methods, unbiased signals even when virus aggregates are formed, and the ability to decouple inactivation kinetics from transport phenomena. Additionally, the signal reflects the removal and transport of the studied microorganism and not a surrogate.     

Effect of the licensing process on hygiene in retail butchers' premises in the West Midlands,United Kingdom

As the result of a change in legislation, all retail butchers in England were required to be licensed by 1 November 2000. A fully implemented hazard analysis critical control point plan was a condition of the license. This longitudinal study assessed the effect of licensing on hygiene in a group of retail butchers in the West Midlands, England. A hygiene audit and environmental sampling were used to determine if the licensing process improved hygiene in the study group. At the end of the study, 30% of the original group were no longer trading as they had been, having either altered the product they were selling or ceased to trade. The remaining butchers showed a significant improvement in the hygiene of their premises, both in the audit scores and in the environmental sampling. The mean audit score for the group had improved from an initial score of 47.54 to 54.95 (P < 0.02). The contamination with Enterobacteriaceae on equipment used for cooked meat had also improved, decreasing from mean contamination levels of 1.38 log CFU/cm2 before licensing to mean contamination levels of -0.11 log CFU/cm2 after licensing (P < 0.00001).     

Organically modified silica sol-mediated capillary electrophoresis

We describe in this paper the use of ormosil (organically modified silica) sols as additives to the run buffer for selectivity manipulations between solutes in capillary electrophoresis. CE systems that contain sol additives in the run buffer can be thought of as pseudocapillary electrochromatography. Three sols based on different types of silanes were studied. Methyltrimethoxysilane (MTMOS)-based sol was found to improve selectivities between various aromatic acids. Aminopropyltrimethoxysilane (APS) sol interacts differently with structural isomers of aromatic acids than does MTMOS. At low pH with APS sol in the run buffer, neutral solutes can be separated, as well. The separation of the neutral solutes seems to be facilitated by the formation of hydrogen bonds between the solutes and the APS sol. APS and N-[3-(trimethoxysilyl)propyl]-ethylenediamine (EDAS) affect the separation of the same compounds differently, thus indicating that even small changes of the functional groups of the sol have pronounced effect on the interactions between the sols and the solutes.     

The effects of suppressing a negative autobiographical memory on concurrent intrusions and subsequent autobiographical recall in dysphoria.

Depressed individuals endeavor to suppress intrusive thoughts and memories as a form of mood control. Two predictions from this literature were examined. The 1st was that attempts to suppress a preselected negative memory during a stream-of-consciousness (SOC) task in dysphoric individuals, relative to a no-suppress condition, would lead to relatively speeded access to other negative but not positive memories on a subsequent cue-word recall task. No such effects were predicted for nondysphoric controls. The 2nd prediction was that, across all participants who were asked to suppress memories, higher levels of depressed mood would be associated with more intrusions of the to-be-suppressed memory during the SOC and that this association would be stronger than the comparable relation in participants who were not asked to suppress memories. Results support both predictions. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Electrochemical waste water treatment: Electrooxidation of acetaminophen

Oxidation of acetaminophen at boron-doped diamond (BDD) and at Ti/SnO₂ anodes in a plug-flow divided electrochemical reactor led to electrochemical combustion, whereas at Ti/IrO₂ benzoquinone was the exclusive product except at very long electrolysis times. The difference is explicable in terms of the different mechanisms of oxidation: direct oxidation at the anode for Ti/IrO₂ vs. indirect oxidation involving electrogenerated hydroxyl radicals at BDD and Ti/SnO₂. At BDD, at which the efficiency of degradation of acetaminophen was greatest, the rate of electrolysis at constant concentration was linearly dependent on the current, and at constant current linearly dependent on the concentration. Current efficiencies for mineralization up to 26% were achieved without optimization of the cell design.
