Exercise Makes You Feel Good, But Does Feeling Good Make You Exercise?: An Examination Of Obese Dieters, Robert Albert Carels, Carissa Coit, Bonnie Berger Dec 2007

Exercise Makes You Feel Good, But Does Feeling Good Make You Exercise?: An Examination Of Obese Dieters, Robert Albert Carels, Carissa Coit, Bonnie Berger

Robert Albert Carels

Whereas exercise-induced mood enhancement has been well documented, the relationship between mood and exercise participation is less well understood. Mood states influence evaluative judgments that could plausibly influence a decision to exercise. Further, most exercise-mood research is limited to normal weight adults in response to a single exercise session. The current investigation examines the influence of (a) morning mood on exercise, (b) exercise intensity/duration on mood enhancement, and (c) daily change in mood on exercise days compared with nonexercise days in obese behavioral weight loss program (BWLP) participants. Participants (N=36) recorded morning, evening, and pre- and postexercise mood, as well …


Evidence Of Recycling Of Lead Battery Waste Into Highly Leaded Jewelry, Jeffrey D. Weidenhamer, Micheal L. Clement Nov 2007

Evidence Of Recycling Of Lead Battery Waste Into Highly Leaded Jewelry, Jeffrey D. Weidenhamer, Micheal L. Clement

Jeffrey D. Weidenhamer

Inexpensive highly leaded jewelry, much of it imported from China, remains widely available in the United States. The source materials for these items are unknown. Due to the low cost of much of this trinket jewelry, it seems likely that scrap materials may be used in their manufacture. Thirty-nine jewelry items previously determined to contain 90% or more lead by weight were analyzed for antimony content. The average antimony content of these thirty-nine items was 3.0%. The range of antimony content in the samples was from 0.3% to 6.2% antimony by weight, with twenty-seven of the samples in the range …


Leaded Electronic Waste Is A Possible Material For Lead-Contaminated Jewelry, Jeffrey D. Weidenhamer, Michael L. Clement Oct 2007

Leaded Electronic Waste Is A Possible Material For Lead-Contaminated Jewelry, Jeffrey D. Weidenhamer, Michael L. Clement

Jeffrey D. Weidenhamer

Highly leaded jewelry, often imported from China, remains widely available in the United States. Leaded electronic waste is exported from the United States to several Asian countries where solder is recovered and circuit boards are stripped of parts in small workshops. To assess whether electronic waste is being recycled into the jewelry, lead, tin and copper content of highly leaded jewelry samples were determined by atomic absorption spectrometry. Sixteen jewelry items previously determined to contain 20–80% lead by weight were analyzed. Samples were digested in nitric acid for analysis of lead and copper, and in aqua regia for analysis of …


Sorption-Enhanced Steam Reforming Of Hydrocarbons With Autothermal Sorbent Regeneration In A Moving Heat Wave Of Catalytic Combustion Reaction, Andrey N. Zagoruiko, Alexey G. Okunev Jul 2007

Sorption-Enhanced Steam Reforming Of Hydrocarbons With Autothermal Sorbent Regeneration In A Moving Heat Wave Of Catalytic Combustion Reaction, Andrey N. Zagoruiko, Alexey G. Okunev

Andrey N Zagoruiko

Novel technological concept of sorption-enhanced hydrocarbon steam reforming with autothermal regeneration of the carbon dioxide scavenger in the moving super-adiabatic heat wave of the exothermic catalytic combustion reaction performed directly inside the adsorption-catalytic bed is presented. Process modelling results, confirming the capability and high efficiency of the proposed technological approach, are discussed. It is shown that proposed approach opens the way for creation of cheap, reliable and energy-saving adiabatic packed bed methane processors of unlimited processing capacity.


Controlling The Interplay Of Large Organic Ions: Para-Sulfonato-Calix 4 Arene And Phosphonium Cations, Yatimah Alias Jan 2007

Controlling The Interplay Of Large Organic Ions: Para-Sulfonato-Calix 4 Arene And Phosphonium Cations, Yatimah Alias

Yatimah Alias

Materials based on polyanionic para-sulfonato-calix[ 4] arene and tetraphenylphosphonium (Ph4P+) or benzyltriphenylphosphonium (BzPh(3)P(+)) cations are built up via partial inclusion and extensive phenyl embracing in association with trivalent cations (Yb3+, Gd3+ and Er3+). The crystalline materials have layered structures and feature negatively-charged channels propagating through the solids.

2-Aminopyrimidine-3,3,3-Triphenyl- Propanoic Acid (1/1), Mateusz F. Serafin, Kraig A. Wheeler

Kraig A. Wheeler

The title bimolecular compound, C4H5N3·C21H18O2, constructed from 2-aminopyrimidine and 3,3,3-triphenylpropanoic acid, forms a tetramolecular hydrogen-bonded motif via O—H...N, N—H...O and N—H...N contacts. This aggregate organizes to give crystal-packing motifs with hydrophilic and hydrophobic regions.
