Nitrogen and Phosphorus Removal from Wastewater Treatment Plant Effluent via Bacterial Sulfate Reduction in an Anoxic Bioreactor Packed with Wood and Iron (2014)

We investigated the removal of nitrogen and phosphate from the effluent of a sewage treatment plant over a long-term operation in bioreactors packed with different combinations of wood and iron, with a trickling filter packed with foam ceramics for nitrification. The average nitrification rate in the trickling filter was 0.17 kg N/m3∙day and remained at 0.11 kg N/m3∙day even when the water temperature was below 15 °C. The denitrification and phosphate removal rates in the bioreactor packed with aspen wood and iron were higher than those in the bioreactor packed with cedar chips and iron. The bioreactor packed with aspen wood and iron continued to remove nitrate and phosphate for >1200 days of operation. The nitrate removal activity of a biofilm attached to the aspen wood from the bioreactor after 784 days of operation was 0.42 g NO3-N/kg dry weight wood∙ day. There was no increase in the amount of dissolved organic matter in the outflow from the bioreactors.
Effect of external optical feedback on spectral properties of external cavity semiconductor lasers (1984)

The effects of external optical feedback on the spectral properties of single-mode external cavity semiconductor lasers that use a graded-index (GRIN) lens in the optical cavity have been investigated. Mode rejection ratio and intensity drop-out rate of the dominant mode as a function of optical strength have been measured. These measurements show that a laser with a short (160 μm) GRIN-lens external cavity can tolerate optical feedback as large as −20 dB without significant penalty. This minimum optical feedback can be larger when lasers with shorter cavity length are used.
Traditional versus Televised Instructional Methods for Introductory Psychology (1980)

This study compared the performance of students in a televised introductory psychology course to that of students in a traditional introductory psychology course at a community college. All students had the same instructor and textbook. They took approximately the same tests. Students in the televised introductory course did significantly better than those in the traditional introductory course. These two groups were also compared on the basis of age, sex, and scores on the Sixteen Personality Factors Inventory. Students in the televised psychology course were more happy-go-lucky, conscientious, trusting, astute, controlled and less apprehensive. They were also considerably older. Students' evaluation of the TV course, text, and study guide were favorable. More students successfully completed the on-campus psychology course.
Nucleotide sequences of the genes regulating O-polysaccharide antigen chain length (rol) from Escherichia coli and Salmonella typhimurium: protein homology and functional complementation (1992)

In this article, we report on the nucleotide sequences of the rol genes of Escherichia coli O75 and Salmonella typhimurium LT2. The rol gene in E. coli was previously shown to encode a 36-kDa protein that regulates size distribution of the O-antigen moiety of lipopolysaccharide. The E. coli and S. typhimurium rol gene sequences consist of 978 and 984 nucleotides, respectively. The homology between the nucleotide sequences of these two genes was found to be 68.9%. Both the E. coli rol and S. typhimurium rol genes are transcribed counter to the histidine operon and code for deduced polypeptides of 325 and 327 amino acids, respectively. The S. typhimurium rol gene was previously identified to encode a protein of unknown function and to share a transcription termination region with his. The homology between these deduced polypeptide sequences was observed to be 72%. A complementation test was performed in which the S. typhimurium rol gene was placed in trans with an E. coli plasmid (pRAB3) which encodes the O75 rfb gene cluster and not rol. The protein expressed from the S. typhimurium rol gene was found to regulate the distribution of the O75 O polysaccharide on the lipopolysaccharide of the host strain, E. coli S phi 874. The mechanism of Rol action may be independent of O antigen subunit structure, and its presence may be conserved in members of the family Enterobacteriaceae and other gram-negative bacilli that express O polysaccharides on their surface membrane.
Can autism be triggered by acetaminophen activation of the endocannabinoid system? (2010)

Acetaminophen use in children has been associated with increased autism risk. Recent evidence suggests that acetaminophen's analgesic actions result from activation of the endocannabinoid system, and activation of this system can have neuromodulatory consequences during development. This investigation was performed to determine if there is evidence to support the hypothesis that acetaminophen use can trigger autism by activation of the endocannabinoid system.
Radiocarbon dioxide detection based on cavity ring-down spectroscopy and a quantum cascade laser (2015)

Monitoring of radiocarbon (C14) in carbon dioxide is demonstrated using mid-infrared spectroscopy and a quantum cascade laser. The measurement is based on cavity ring-down spectroscopy, and a high sensitivity is achieved with a simple setup. The instrument was tested using a standardized sample containing elevated levels of radiocarbon. Radiocarbon dioxide could be detected from samples with an isotopic ratio C14/C as low as 50 parts-per-trillion, corresponding to an activity of 5 kBq/m(3) in pure CO(2), or 2 Bq/m(3) in air after extraction of the CO(2) from an air sample. The instrument is simple, compact, and robust, making it the ideal tool for on-site measurements. It is aimed for monitoring radioactive gaseous emissions in a nuclear power environment, during the operation and decommissioning of nuclear power plants. Its high sensitivity also makes it the ideal tool for the detection of leaks in radioactive waste repositories.

Sub-μm Josephson Junctions for Superconducting Quantum Devices (2012)

For high-performance superconducting quantum devices based on Josephson junctions (JJs) decreasing lateral sizes is of great importance. Fabrication of sub-μm JJs is challenging due to non-flat surfaces with step heights of up to several 100 nm generated during the fabrication process. We have refined a fabrication process with significantly decreased film thicknesses, resulting in almost flat surfaces at intermediate steps during the JJ definition. In combination with a mix-&-match process, combining electron-beam lithography (EBL) and conventional photolithography, we can fabricate JJs with lateral dimensions down to 0.023 μm^2. We propose this refined process as an alternative to the commonly used chemical-mechanical polishing (CMP) procedure. We present transport measurements of JJs at 4.2 K that yield critical-current densities in the range from 50 to 10^4 A/cm^2. Our JJ process yields excellent quality parameters, Rsg/Rn up to ~50 and Vgap up to 2.81 mV, and also allows the fabrication of high-quality sub-μm wide long JJs (LJJs) for the study of Josephson vortex behavior. The developed technique can also be used for similar multilayer processes and is very promising for fabricating sub-μm JJs for quantum devices such as SQUIDs, qubits and SIS mixers.
Tamoxifen and Chemotherapy for Axillary Node-Negative, Estrogen Receptor–Negative Breast Cancer: Findings From National Surgical Adjuvant Breast and Bowel Project B-23 (2001)

There was no significant difference in the outcome of patients who received AC or CMF. TAM with either regimen resulted in no significant advantage over that achieved from chemotherapy alone.
Pipemidic Acid: Its Activities Against Various Experimental Infections (1976)

Pipemidic acid, a structural relative of piromidic and nalidixic acids, exhibited substantial therapeutic activity when it was administered orally to mice bearing either widely disseminated or relatively localized infections with Staphylococcus aureus and a variety of gram-negative bacilli. The activity of pipemidic acid was always greater than that of piromidic and nalidixic acids; in infections with Pseudomonas aeruginosa and in bacilli resistant to the latter two drugs, pipemidic acid exhibited significant activity. In limited comparative studies, the activities of pipemidic acid were generally superior to the activities of cephalexin, ampicillin, and carbenicillin. Gentamicin, administered subcutaneously, was more active than pipemidic acid, given either orally or subcutaneously, against both systemic and localized infections with P. aeruginosa. The therapeutic accomplishments of pipemidic acid were attained with well-tolerated doses.
Isolation of Thermotolerant Freeliving Amebae from Lake Tenkiller, Oklahoma (1996)

Pathogenic freeliving amebae cause serious human disease including infection of the eye and central nervous system.Disease-producing freeliving amebae are able to grow at 37 °C or higher, and are considered to be thermotolerant.Nonpathogenic species are often, although not always, thermointolerant. We sampled the water at various depths in LakeTenkiller to isolate thermotolerant and, therefore, potentially pathogenic freeliving amebae. Pathogenicity was tested byintranasal inoculation of amebae into mice. The prevalence of thermotolerant amebae in the water sampled was 1 ameba/171ml; however, no pathogenic amebae were isolated.
Suppression of Cancer Cell Migration and Invasion by Protein Phosphatase 2A through Dephosphorylation of μ- and m-Calpains (2006)

The mu- and m-calpains are major members of the calpain family that play an essential role in regulating cell motility. We have recently discovered that nicotine-activated protein kinase C iota enhances calpain phosphorylation in association with enhanced calpain activity and accelerated migration and invasion of human lung cancer cells. Here we found that specific disruption of protein phosphatase 2A (PP2A) activity by expression of SV40 small tumor antigen up-regulates phosphorylation of mu- and m-calpains whereas C2-ceramide, a potent PP2A activator, reduces nicotine-induced calpain phosphorylation, suggesting that PP2A may function as a physiological calpain phosphatase. PP2A co-localizes and interacts with mu- and m-calpains. Purified, active PP2A directly dephosphorylates mu- and m-calpains in vitro. Overexpression of the PP2A catalytic subunit (PP2A/C) suppresses nicotine-stimulated phosphorylation of mu- and m-calpains, which is associated with inhibition of calpain activity, wound healing, cell migration, and invasion. By contrast, depletion of PP2A/C by RNA interference enhances calpain phosphorylation, calpain activity, cell migration, and invasion. Importantly, C2-ceramide-induced suppression of calpain phosphorylation results in decreased secretion of mu- and m-calpains from lung cancer cells into culture medium, which may have potential clinic relevance in controlling metastasis of lung cancer. These findings reveal a novel role for PP2A as a physiological calpain phosphatase that not only directly dephosphorylates but also inactivates mu- and m-calpains, leading to suppression of migration and invasion of human lung cancer cells.

Modification of the second-order optical nonlinearities in AlGaAs asymmetric multiple quantum well waveguides by quantum well intermixing (1997)

We demonstrate that a quantum well intermixing technique can be used to control the second-order nonlinearity χzzz(2) in an AlGaAs asymmetric coupled quantum well waveguide structure at 1.52 μm. Photoluminescence measurements also indicate that the spatial resolution of the impurity-free vacancy disordering process used for quantum well intermixing is better than 1.5 μm which should be sufficient for first-order quasiphase-matched second harmonic generation.
Future Directions of the Conferencing and Collaboration Field (2012)

In this paper, the authors discuss fifteen semi-structured interviews carried out in 2010 with international industry experts and thought leaders within the conferencing and collaboration (C&C) field. The interviews focused on 5, 10, and 15-year time frames, and sought to elicit predictions on the components and services of future C&C platforms, as well as organisational issues such as the likely impacts on business value chains. The authors performed Affinity Diagramming / KJ Analysis in order to assess common themes and impose structure on the information gathered in the interviews. Themes included ease of use, improved presence/social context, formalised social networking capabilities, virtual worlds, remote interactive tools, meta-knowledge / context capture, identity and trust, and key barriers to C&C uptake across organisations. Pre-conditions for maturation of the field include the emergence of interoperability and standards, and the development of corporate education policies.
Concentration of Antioxidant Polyphenols from <i>Thymus capitatus</i> extracts by Membrane Process Technology (2012)

Thymus capitatus is a Mediterranean plant characterized by its antioxidant polyphenols of which the most known are the carnosic and rosmarinic acids. In this way, this study aims to concentrate these acids by membrane processes. The thyme essential oil composition was established by capillary GC-MS and 27 components were identified representing 98.93%± 1.97% of total oils. The antioxidant test for permeate and retentate of methanolic and aqueous extract were determined using 3 types of membranes. The results showed that the synthetic NF membrane is able to trap and concentrate phenolic compounds in the retentate much better than the NF commercial and UF synthetic membrane. The results of the total phenolic content (TPC) showed a significant value of the polyphenol content present in the aqueous extract with 175.53 mg Gallic Acid Equivalents (GAE)/g of extract. The spectrum of the aqueous extract of Thymus capitatus showed the presence of 3 visible peaks, the 1st one at 217 nm corresponding to the carnosic acid, the 2nd one at 277 nm for essential oils, and the last one at 326 nm attributed to the rosmarinic acid. The commercial membrane NF-DK succeeded to concentrate rosmarinic acid and can be considered as a stage towards the concentration of this product with a high added value.

Neutralisation of the antibacterial action of quaternary ammonium compounds with cyclodextrins (1992)

Cyclodextrins can be used to inactivate the antimicrobial activity of quaternary ammonium biocides. Their use offers several advantages over other methods which employ non-ionic detergents or phospholipids.
Stress response, cell death and signalling: the many faces of reactive oxygen species (2003)

Plants respond to pathogens and abiotic stresses by transient increases in the production of reactive oxygen species (ROS) and ion fluxes, which activate both local programmed cell death and systemic increases in stress‐ and pathogen‐resistance. The present essay explores the emerging complexity of the multiple roles that ROS play in intra‐ and intercellular communication in both stressed and unstressed organisms.

Overview of transcriptomic analysis of all human proteases, non-proteolytic homologs and inhibitors: Organ, tissue and ovarian cancer cell line expression profiling of the human protease degradome by the CLIP-CHIP™ DNA microarray (2017)

The protease degradome is defined as the complete repertoire of proteases and inhibitors, and their nonfunctional homologs present in a cell, tissue or organism at any given time. We review the tissue distribution of virtually the entire degradome in 23 different human tissues and 6 ovarian cancer cell lines. To do so, we developed the CLIP-CHIP™, a custom microarray based on a 70-mer oligonucleotide platform, to specifically profile the transcripts of the entire repertoire of 473 active human proteases, 156 protease inhibitors and 92 non-proteolytically active homologs known at the design date using one specific 70-mer oligonucleotide per transcript. Using the CLIP-CHIP™ we mapped the expression profile of proteases and their inhibitors in 23 different human tissues and 6 ovarian cancer cell lines in 104 sample datasets. Hierarchical cluster analysis showed that expression profiles clustered according to their anatomic locations, cellular composition, physiologic functions, and the germ layer from which they are derived. The human ovarian cancer cell lines cluster according to malignant grade. 110 proteases and 42 inhibitors were tissue specific (1 to 3 tissues). Of these 110 proteases 69% (74) are mainly extracellular, 30% (34) intracellular and 1% intramembrane. Notably, 35% (197/565) of human proteases and 30% (47/156) of inhibitors were ubiquitously expressed in all 23 tissues; 27% (155) of proteases and 21% (32) of inhibitors were broadly expressed in 4-20 tissues. Our datasets provide a valuable resource for the community of baseline protease and inhibitor relative expression in normal human tissues and can be used for comparison with diseased tissue, e.g. ovarian cancer, to decipher pathogenesis, and to aid drug development.

All-Solid-State Thin-Film Rechargeable Lithium Batteries Using Solid Redox Polymerization Electrodes (1989)

Lithium batteries using solid redox polymerization electrodes maintain the advantages of all-so lid-state thin-film systems while overcoming the limitations of using intercalation compounds as cathodes (Le., insufficient rate capability and unsatisfactory cathode utilization).Laboratory Li/PEO ISRPE cells have already demonstrated much higher power capability, energy density, and cathode utilization than analogous Li/PEO/TiS2 cells.One of the Li/PEO/SRPE cells has achieved 350 cycles from 50 0C to 93 oC wi~h a sustained energy density of 264 Wh/kg (241 Wh/l), power density of 160 W /kg (144 W II), and 38% to 75% of cathode utilization at 90% voltage efficiency.At 100 oC, power densities of over 2400 W /kg and energy density of 200 Wh/kg have been achieved with up to 96% utilization of cathode capacity.At ambient temperatures, the cells can be discharged at a current density of 250 ~/cm2, achieving a film capacity of 0.5 coulombs/cm 2 .
Séquençage du gène de la chitosanase de Streptomyces N174 et surexpression dans Streptomyces lividans TK24 (1993)

Notre laboratoire a récemment isolé un actinomycète Streptomyces N174 capable de produire l'exoenzyme chitosanase. Le gène de la chitosanase a été cloné précédemment dans Streptomyces lividans TK24 à l'aide du vecteur à grand nombre de copies pIJ702. Mon projet de recherche a débuté avec la localisation du gène de la chitosanase par hybridation avec un oligonucléotide, sur un fragment d'ADN de 2.78 Kb. La séquence en nucléotides du gène de la chitosanase a par la suite été déterminée, ce qui a permis de définir sa structure, ses particularités ainsi que l'homologie éventuelle avec d'autres gènes. Une caractérisation des éléments régissant le contrôle de l'expression du gène de la chitosanase (promoteur et terminateur de transcription, peptide signal) a par la suite été accomplie. Certaines études sur la sécrétion de cette protéine chez Escherichia coli, une bactérie Gram­négative ont également été effectuées. Suite à ces observations, nous avons tenté de surexprimer le gène de la chitosanase à l'aide de manipulations génétiques, c'est-à-dire par remplacement du promoteur natif par divers promoteurs constitutifs et régulés.
