Growth and characterization of Cu 2 ZnSnS 4 nanostructures using anodized aluminum as the growth mask (2009)

In this paper we report the growth and characterization of Cu<sub>2</sub>ZnSnS<sub>4</sub> (CZTS) nanostructures by co-electrodeposition technique using CuCl<sub>2</sub>, SnCl<sub>2</sub> and ZnCl<sub>2</sub> as sources and choline-based ionic liquid (IL) as the electrolyte. X-ray diffraction analysis of CZTS thin films grown by this technique indicated that the films have a kesterite structure with preferred grain orientation along (112). It is found that the energy bandgap of the material is about 1.49eV and the optical absorption coefficient is in the order of 10<sup>4</sup>cm<sup>-1</sup>. Anodized aluminum oxide (AAO) was used as the growth mask for the growth of the nanostructures. Anodization of the aluminum foil was carried out in phosphoric acid solution at 1°C and a potential of 40 to 100V was applied. Sulfurization of the rods was performed in elemental sulfur vapor at 450°C for four hours using N<sub>2</sub> as the ambient gas. Experimental results show that nanotubes were formed using the technique and the diameter can be well controlled by varying the applied potential in the anodization process. Electron diffraction experiments show that a mixture of single- and poly-crystalline nanostructures was found.
Amplification and reshaping of optical solitons in a glass fiber-IV: Use of the stimulated Raman process (1983)

By use of the stimulated Raman process, optical solitons can be amplified and reshaped while they propagate through a glass fiber. When an appropriate level is chosen for the pump power (10-100 mW for 10-psec solitons), the solitons can be reshaped adiabatically. The method allows the separation between two repeaters (amplifiers) to be decided by the fiber loss rather than by the fiber dispersion.
Sequential Expectancies and Decision Making in a Changing Environment: An Electrophysiological Approach (1982)

ABSTRACT This experiment addressed two questions. First, we sought to determine how sequential expectancies, as indexed by the amplitude of P300, are formulated when subjects are presented with a series in which the event probabilities are continuously changing. Second, we wanted to determine the effect on P300 amplitude of seeking information prior to a decision when the decisions are required at random intervals. Eight subjects were presented with a Bernoulli series of high and low tones in which the event probabilities reversed at random intervals. Thus, while the event probabilities were either .33 or .67 over short segments of the series, they were .50 over each trial block. The subject's task was to count the number of low‐pitched tones. In two separate conditions (“Unknown” and “Known”) the subjects received different information about the series. In the Unknown condition, the subjects were not informed of the reversals in stimulus probability and were only told that the events were equally probable. In the Known condition, the subjects were informed of the probability reversals and, in addition to the counting task, were asked to detect the probability reversals. The trials were divided into two categories: “transition” and “stable.” The transition trials were those that occurred between the actual probability reversal and the subject's reported detections. The stable trials were all those not included in the transition category. The data from the stable trials revealed that, in most cases, subjects generated their expectancies, as indexed by the amplitude of P300, in an identical manner during both conditions. Accurate knowledge of the stimulus probabilities did, however, influence the amplitude of P300 for events that were preceded by sequences of stimuli that occur only rarely at each level of probability. These data suggest that the mechanism responsible for generating sequential expectancies is largely automatic. Certain aspects of this mechanism are, however, modulated by the subject's knowledge of the parameters of the series. The data from the transition trials revealed that, in the Unknown condition, the subjects’ assignments of subjective probabilities, as indexed by the amplitude of P300, adapted rapidly to meet the new sequence‐generating rules following the probability transitions. In contrast, during the Known condition, the amplitude of the P300 and Slow Wave components steadily increased, as the decision point approached, to levels well above those in the Unknown condition. By the first trial following the decision, this enhancement in P300 and Slow Wave activity was no longer evident. These results are discussed in terms of a descriptive model of the subjects’ decision making behavior.

Non-invasive positive pressure ventilation (CPAP or bilevel NPPV) for cardiogenic pulmonary oedema (2013)

NPPV in addition to standard medical care is an effective and safe intervention for the treatment of adult patients with acute cardiogenic pulmonary oedema. The evidence to date on the potential benefit of NPPV in reducing mortality is entirely derived from small-trials and further large-scale trials are needed.
β-GALACTOSIDE-BINDING LECTIN OF VERTEBRATES (1990)

k Da have been found up to now. These lectins were separated from electric eels, chickens and a variety of mammals. Reducing agents, not metal ions, are required for their stabilization. They don't exist in a free state in body fluid and are solubilized when tissues are extracted with S-galacto-
The DNA‐binding properties of an artificial 42‐residue polypeptide derived from a natural repressor (1993)

Bacteriophage 434 repressor recognizes the operator sequences ACAAG and ACAAT. As the same or similar sequences occur in the enhancer region of HIV-1, 434 repressor was a potential HIV enhancer-binding protein. We found that the interaction of the DNA-binding domain of 434 repressor with a 57-bp HIV enhancer DNA was very weak whereas a 42-residue construct, comprising the recognition helix and four copies of a positively charged segment of the repressor, bound strongly. The results of footprint and cell-free in vitro transcription studies showed that the 42-residue peptide bound preferably to the enhancer region of HIV-1 and acted as an artificial repressor. Replacement of an essential glutamine of the recognition helix by glutamic acid resulted in a partial shift of the sequence specificity of the 42-residue peptide.
Performance Study of a Multifuel Engine Operating Simultaneously with CNG and Ethanol in Various Proportions (2008)

<div class="htmlview paragraph">The technological development of automotive engines is focused on alternative energy sources and optimized use of conventional fuels. The current flexible engines in Brazil can operate with gasohol and ethanol blends in any proportion, but the flexibility is restricted to liquid fuels. The present investigation consists on the use of electronic injection systems for ethanol and for CNG, allowing the use of these fuels simultaneously. The objective of this work is to determine the best proportion of CNG-ethanol mixture in order to maximize the use of the natural gas, fuel which offers the lowest BSFC on conventional SI engines. The low volumetric efficiency inherent in the use of CNG is compensated by the injection of a small quantity of ethanol. The latent heat of vaporization of the alcohol is used to take heat from the intake air and increase its mass, taking advantage from the high latent heat of vaporization of the ethanol and the low BSFC of the CNG. The present investigation is a pioneer study concerning the simultaneous use of CNG and ethanol and is a breakthrough in the development of new management strategies on a flexible engine. The ethanol-CNG mixture proportion and the stoichiometry could be set according to the torque demand but always giving priority to the CNG, with results on low BSFC (compared to the exclusive use of ethanol).</div>
Placebo/Nocebo Symptom Reporting in a Sham Herbal Supplement Trial (2006)

The present study examined reports of placebo and nocebo symptoms in a college sample. The study was presented under the guise of a clinical trial to evaluate the effectiveness of an over-the-counter herbal supplement intended to enhance cognitive performance. Participants were informed they would be receiving either an herbal supplement or a placebo, and each was provided with a mock list of possible beneficial and adverse effects of the “supplement.” In fact, all participants received placebo. Symptoms were endorsed by a significant majority of participants following placebo ingestion. More important, results indicated that the few participants who believed they received an herbal supplement endorsed (via self-report) significantly more symptoms than those who believed they received a placebo. Neither anxiety nor social desirability was significantly related to symptom reporting. Results suggest that beliefs concerning treatment received may subsequently affect the degree of placebo response in a no-treatment group. Implications for clinical trials and future research are discussed.
1.55 µm GaInAsP/InP Distributed Feedback Lasers (1981)

Room temperature operation of 1.55 µm GaInAsP/InP distributed feedback lasers is reported. The laser was fabricated by a single LPE growth cycle on a corrugated substrate. Single longitudinal and transverse mode oscillation was observed up to 1.7 times the threshold current. The temperature dependence of lasing wavelength was about 0.09 nm/deg.
Studies in Australian Amphibia. 1. The genus <i>Crinia</i> Tschudi in South-western Australia and some species from south-eastern Australia. (1957)

The Western Australian representatives of the genus Crinia Tschudi are reviewed. On the basis of field observations and data from in vitro crosses it is concluded that the following species occur in south-western Australia: Crinia rosea Harrison, C. leai Fletcher, C. georgiana Tschudi, C. glauerti Loveridge, C. insignifera Moore, and a new species. From in vitro crosses, Moore's (1954) conclusion that C. signifera Girard does not occur in the south-west of Australia is confirmed. C. glauerti is regarded as a western representative of the C. signifera super-species. Collections in eastern Australia revealed the presence of an undescribed species which is a representative of the C. insignifera super-species. Life history data are presented.
Short-Chain Fatty Acid Activation by Acyl-Coenzyme A Synthetases Requires SIR2 Protein Function in <i>Salmonella enterica</i> and <i>Saccharomyces cerevisiae</i> (2003)

SIR2 proteins have NAD(+)-dependent histone deacetylase activity, but no metabolic role has been assigned to any of these proteins. In Salmonella enterica, SIR2 function was required for activity of the acetyl-CoA synthetase (Acs) enzyme. A greater than two orders of magnitude increase in the specific activity of Acs enzyme synthesized by a sirtuin-deficient strain was measured after treatment with homogeneous S. enterica SIR2 protein. Human SIR2A and yeast SIR2 proteins restored growth of SIR2-deficient S. enterica on acetate and propionate, suggesting that eukaryotic cells may also use SIR2 proteins to control the synthesis of acetyl-CoA by the level of acetylation of acetyl-CoA synthetases. Consistent with this idea, growth of a quintuple sir2 hst1 hst2 hst3 hst4 mutant strain of the yeast Saccharomyces cerevisiae on acetate or propionate was severely impaired. The data suggest that the Hst3 and Hst4 proteins are the most important for allowing growth on these short-chain fatty acids.
Rapid annealing and the anomalous diffusion of ion implanted boron into silicon (1987)

The anomalous diffusion of ion implanted boron into silicon is shown to be a transient effect with a decay time that decreases rapidly with increasing anneal temperature. The decay time is approximately 45 min at 800 °C and decreases to the order of a second at 1000 °C. The anomalous displacement in the low concentration region is greater at low temperatures but a larger fraction of the boron is redistributed at high temperature. Sheet resistance measurements agree with the idea that the moving fraction of the boron atoms is electrically active and limited to the intrinsic carrier concentration at the anneal temperature. The activation energy for the decay of the transient is greater than that for the diffusion coefficient, which makes an appropriate rapid thermal anneal cycle an important practical process in the fabrication of shallow p-n junctions.
Doping Effects of Tetra(amino)fullerene Epoxide in Conducting Polymer Thin Film (2001)

Optical properties and photoconduction of the composites of poly(3-octylthiophene) (PAT-8) and novel C 60 derivatives, tetra(amino)fullerene epoxides (TAFEs) have been studied. TAFEs have high solubility, so heavy doping into conducting polymers is possible in the wet process. PL intensity of PAT-8 has been quenched and photocurrent intensity has been enhanced markedly with increasing the concentration of TAFEs, which can be explained as being due to the photoinduced charge transfer from PAT-8 to TAFEs. In the case of heavy doping of TAFEs into PAT-8, spectral changes in absorption and photoconduction spectra have been observed, which can be interpreted as being due to the charge transfer from PAT-8 to TAFEs in the ground state.
Critical roles of PPARβ/δ in keratinocyte response to inflammation (2001)

The immediate response to skin injury is the release of inflammatory signals. It is shown here, by use of cultures of primary keratinocytes from wild-type and PPAR beta/delta(-/-) mice, that such signals including TNF-alpha and IFN-gamma, induce keratinocyte differentiation. This cytokine-dependent cell differentiation pathway requires up-regulation of the PPAR beta/delta gene via the stress-associated kinase cascade, which targets an AP-1 site in the PPAR beta/delta promoter. In addition, the pro-inflammatory cytokines also initiate the production of endogenous PPAR beta/delta ligands, which are essential for PPAR beta/delta activation and action. Activated PPAR beta/delta regulates the expression of genes associated with apoptosis resulting in an increased resistance of cultured keratinocytes to cell death. This effect is also observed in vivo during wound healing after an injury, as shown in dorsal skin of PPAR beta/delta(+/+) and PPAR beta/delta(+/-) mice.
Anchoring of nematic liquid crystals on mica in the presence of volatile molecules (1993)

Using optical second-harmonic generation, we have studied the orientational order of cyanobiphenyl liquid-crystal monolayers at the interface between a mica crystal and a liquid-crystal film put in the presence of ethylene glycol vapor. These small, volatile molecules adsorb at the mica surface and significantly affect the orientational order of the surface liquid-crystal molecules. As the chemical potential of the volatile molecules was increased, this orientational order first varied continuously, and at a certain stage, exhibited a discontinuous change corresponding to a first-order orientational transition. This surface transition drives the first-order anchoring transition (i.e., the reorientation of the bulk liquid crystal) previously observed in these systems.
The Enethiolate Anion Reaction Products of EpiD (1997)

One of the steps involved in the biosynthesis of the lantibiotic epidermin is the oxidative decarboxylation reaction of peptides catalyzed by the flavoenzyme EpiD. EpiD catalyzes the formation of a (Z)-enethiol derivative from the C-terminal cysteine residue of the precursor peptide of epidermin and related peptides. The UV-visible spectra of the reaction products of EpiD are pH-dependent, indicating that the enethiol side chain is converted to an enethiolate anion. The pKa value of the enethiol group was determined to be 6.0 and is substantially lower than the pKa value of the thiol side chain of cysteine residues. The increased acid strength of the enethiol side chain compared with that of the thiol group is attributed to the resonance stabilization of the negative charge of the anion.
Cathepsin K in Adipocyte Differentiation and Its Potential Role in the Pathogenesis of Obesity (2006)

CTSK, a cysteine protease involved in extracellular matrix remodeling, could be one of the determinants of adipocyte differentiation. CTSK may be involved in the pathogenesis of obesity by promoting adipocyte differentiation.
Simulation, acquisition and analysis of passive millimeter-wave images in remote sensing applications (2008)

We report on the development of a passive millimeter-wave (MMW) imager for remote sensing, and the comparison of the experimentally acquired images with the theoretical images from our MMW scene simulator. The imager has an aperture diameter of 0.6m, and the detector and the imaging optics are mechanically raster-scanned over the scene to form an image. The angular resolution was experimentally found to be 0.4 degrees, which is close to the theoretical diffraction limit of 0.37 degrees, and the imager NEDT was measured to be 0.9 K. Qualitatively, simulated MMW imagery showed good agreement with an experimental MMW image.
Neanderthals and us (2010)

Recent archaeological, fossil and genetic discoveries involving Neanderthals, as well as new interpretations of Neanderthal behaviour, are reviewed in order to examine how similar or different Neanderthals were to early modern humans and, ultimately, to us. It is argued that Neanderthals have been cast in a bad light since their discovery in the 1850s and that prejudice still pervades much research. However, the most extreme views can easily be discounted and a new picture of Neanderthal behaviour and society is emerging. New genetic studies are confirming ideas about interbreeding to the extent that it appears there is a bit of Neanderthal in all people outside of sub-Saharan Africa. It is concluded that the next decade will reveal ever more myth-shattering discoveries, especially in east Asia.

Magnet shaping to reduce induced voltage harmonics in PM machines with surface mounted magnets (1991)

A simple methodology for reducing induced voltage harmonics in permanent magnet (PM) machines by selecting the appropriate magnet shape and dimensions is presented. The method, which uses a simplified analytical model of the magnetic circuit, is applied to three basic magnet shapes (rectangular, stepped, and trapezoidal), and can be extended to more complex geometries. The results of the analytical models are compared with results obtained from finite element analysis and with test results.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Biocompatible Micro-Gel Particles from Cross-Linked Casein Micelles (2007)

The stability of internally cross-linked casein micelles against disruption by urea (which disrupts hydrogen bonds and hydrophobic interactions) and trisodium citrate (which sequesters micellar calcium phosphate) was investigated. Addition of urea (0-6 mol L-1) and/or citrate (0-50 mmol L-1) progressively reduced the turbidity of a suspension of casein micelles cross-linked by transglutaminase and increased particle size (determined by dynamic and static light scattering and small-angle neutron scattering), which was attributed to swelling of the micelles. Furthermore, model calculations, assuming a completely stable casein network, were performed to describe the decreases in turbidity on addition of urea and citrate. Measured and described turbidity values are in agreement, indicating that cross-linking of casein micelles with transglutaminase results in a covalently bound protein network, which is entirely stable to disruption by urea and/or citrate. This may offer potential applications for the use of cross-linked casein micelles as biocompatible protein micro-gel particles.

The lipid composition of <i>Euphausia superba</i> Dana in relation to the nutritional value of <i>Phaeocystis pouchetii</i> (Hariot) Lagerheim (1993)

The fatty acid profiles of Euphausia superba , the Antarctic prymnesiophyte, Phaeocystis pouchetii , and a temperate diatom, Phaeodactylum tricornutum were analysed and compared. The lipid content, lipid class, fatty acid and sterol composition of E. superba fed on each cultured phytoplankton and a mixed diet of both species, were determined. No significant difference was found between total lipid levels of E. superba reared on each of these different diets. Phaeocystis pouchetii , although deficient in a number of the essential fatty acids, is apparently an adequate food source for E. superba. The proportion of polyenoic fatty acids varied within lipid classes although there was no significant difference between levels of the long chain polyunsaturate 20:5(n-3) in the total lipid of E. superba fed on these diets. This acid was found to be less than 1% of the total lipid in Phaeocystis pouchetii compared to 37% in Phaeodactylum tricornutum. This suggests that krill may possess the ability to convert exogenous shorter chain fatty acids to 20:5(n-3) and 22:6(n-3). Significant differences were detected in the isomeric ratio of 16:1(n-7c)/16:0 between krill fed the diatom compared to the prymnesiophyte diet. Significant differences were also detected in several shorter chain fatty acids and between fatty acids within their lipid classes. Such differences may have the potential to be used as biochemical signatures to provide information on food sources and possible feeding grounds of E. superba. Phaeocystis pouchetii in a very late stationary phase, although not used in this feeding study, was found to contain 11% of 22:6(n-3) for which there are few substantive sources in natural algal populations.
