Preparation and Characterization of Ni-Doped TiO2 Materials for Photocurrent and Photocatalytic Applications

Different amounts of Ni-doped TiO2 (Ni = 0.1 to 10%) powders and thin films were prepared by following a conventional coprecipitation and sol-gel dip coating techniques, respectively, at 400 to 800°C, and were thoroughly characterized by means of XRD, FT-IR, FT-Raman, DRS, UV-visible, BET surface area, zeta potential, flat band potential, and photocurrent measurement techniques. Photocatalytic abilities of Ni-doped TiO2 powders were evaluated by means of methylene blue (MB) degradation reaction under simulated solar light. Characterization results suggest that as a dopant, Ni stabilizes TiO2 in the form of anatase phase, reduces its bandgap energy, and adjusts its flat band potentials such that this material can be employed for photoelectrochemical (PEC) oxidation of water reaction. The photocatalytic activity and photocurrent ability of TiO2 have been enhanced by doping of Ni in TiO2. The kinetic studies revealed that the MB degradation reaction follows the Langmuir-Hinshelwood first-order reaction relationship.
An Analysis of Day-Of-The-Week and Intraday Effects in the Indian Stock Market: Evidence from National Stock Exchange

Day of the week effect is one of the most important calendar anomalies that have been observed in many stock markets in all over the world with a lot of different results. Stock markets are speculative market, thus, investors are more concerned about which day is the best for the trade. The primary objective of this paper is to find out the significant day of the week effect in the emerging stock market of a developing country like India for the period January 2001 to December 2012. In order to fulfill the objectives of the paper, 5 models have been estimated. In each model risk factor is defined in different ways thereby leading to different results. Empirical results verify that NSE Nifty50 does not depict such day of the week effects on the intraday and interday stock returns. While index exhibits Wednesday effect on inter-day return of the index, Monday gives lowest return but maximum volatility. However, in certain cases, Friday also suffers from the lowest return indicating presence of reverse weekend effect in the Indian stock market.
Power Output and Force-velocity Relationship of Live Fibres from White Myotomal Muscle of the Dogfish, Scyliorhinus Canicula

Accepted Summary 1. The relationship between force and velocity of shortening and between power and velocity were examined for myotomal muscle fibre bundles from the dogfish. 2. The maximum velocity of shortening, mean value 4-8 ± 0-2 (m s " 1 half sarco-mere" 1 (±S.E.M., N = 13), was determined by the 'slack step' method (Edman, 1979) and was found to be independent of fish length. 3. The force-velocity relationship was hyperbolic, except at the high-force end where the observations were below the hyperbola fitted to the rest of the data. 4. The maximum power output was 91 ± 14 W kg" 1 wet mass (±S.E.M., N = l) at a velocity of shortening of 1-3 ± 0-13/ims" 1 halfsarcomere~ 1 (±S.E.M., N = 7). This power output is considerably higher than that previously reported for skinned fibres (Bone et al. 1986). Correspondingly the force-velocity relationship is less curved for intact fibres than for skinned fibres. 5. The maximum swimming speed (normalized for fish length) predicted from the observed power output of the muscle fibres decreased with increasing fish size; it ranged from 12-9 to 7-8 fish lengths s" 1 for fish 0155-0-645m in length.
Safe electrical stimulation of the cochlear nerve at the promontory during functional magnetic resonance imaging

The purpose of this study was to evaluate possibilities and technical risks for combining intended electrical stimulation of the cochlear nerve and functional magnetic resonance imaging (fMRI). Theoretical considerations and experiments indicate that fMRI can be performed safely during electrical stimulation. A nerve stimulator was developed with minimized length of electrical conductors, current limiting resistance, high inner impedance of a current source, radio frequency (RF)‐shielding, and avoidance of ferromagnetic materials. This nerve stimulator transfers the optically encoded stimulating current signal via a fiber optic cable located near the area of stimulation. There, the optical signal drives an MRI‐compatible current source. This set‐up was tested with transtympanic electrical stimulation of the cochlear nerve at the promontory during an fMRI examination. No hazardous effects could be detected. The stimulation resulted in activation of the Heschl's gyrus. Compared to the conventional promontory testing this method may allow a more objective examination of cochlear implant candidates. Magn Reson Med 42:371–378, 1999. © 1999 Wiley‐Liss, Inc.
Measuring Chronic Poverty

A new class of chronic poverty measures is constructed that builds upon Jalan and Ravallion (1998) but does not require resources in different periods to be perfect substitutes when identifying the chronically poor. We use a general mean to combine the resources of a person into a permanent income standard that is then compared to a poverty line to determine when a person is chronically poor. The parameter of the general mean allows for varying degrees of substitutability over time. The decomposable Clark, Hemming and Ulph (1981) poverty measure is applied to the distribution of permanent income standards to measure overall chronic poverty. Each measure has a convenient expression in terms of a censored matrix and satisfies a host of properties including decomposability. We provide an empirical application of the new measures using panel data from urban areas in Argentina.
Herschel-ATLAS: far-infrared properties of radio-loud and radio-quiet quasars

We have constructed a sample of radio-loud and radio-quiet quasars from the Faint Images Radio Sky at Twenty-one centimetres and the Sloan Digital Sky Survey Data Release 7, over the Herschel-ATLAS Phase 1 area (9h, 12h and 14h.5). Using a stacking analysis, we find a significant correlation between the far-infrared (FIR) luminosity and 1.4-GHz luminosity for radio-loud quasars. Partial correlation analysis confirms the intrinsic correlation after removing the redshift contribution, while for radio-quiet quasars, no partial correlation is found. Using a single-temperature grey-body model, we find a general trend of lower dust temperatures in case of radio-loud quasars compared to radio-quiet quasars. Also, radio-loud quasars are found to have almost constant mean values of dust mass along redshift and optical luminosity bins. In addition, we find that radio-loud quasars at lower optical luminosities tend to have on average higher FIR and 250-μm luminosity with respect to radio-quiet quasars with the same optical luminosites. Even if we use a two-temperature grey-body model to describe the FIR data, the FIR luminosity excess remains at lower optical luminosities. These results suggest that powerful radio jets are associated with star formation especially at lower accretion rates.
The Circumgalactic Environment of Bright IRAS Galaxies

This paper systematically studies, for the first time, the circumgalactic environment of bright IRAS galaxies as defined in 1989 by Soifer and coworkers. While the role of gravitational interaction for luminous and ultraluminous IRAS galaxies has been well established by various studies, the situation is by far more obscure in the IR luminosity range of the bright IRAS sample, 1010 L☉ ≲ LFIR ≲ 1011 L☉. To easily identify nearby companion galaxies, the bright IRAS sample is restricted to 87 objects with redshift range 0.008 ≤ z ≤ 0.018 and Galactic latitude δ ≥ . A control sample, selected from the CfA redshift-survey catalog, includes 90 objects matching the IRAS bright galaxy survey sample for distribution of isophotal diameter, redshift, and morphological type. From a search of nearby companion galaxies within 250 kpc in the second-generation Digitized Sky Survey (DSS-II), we find that the circumgalactic environments of bright IRAS galaxies contain more large companions than the galaxies in the optically selected control sample and are similar to those of Seyfert 2 galaxies. We find a weak correlation over a wide range of far-IR luminosity (109 L☉ ≲ LFIR ≲ 1012.5 L☉) between projected separation and LFIR, which confirms a very close relationship between the star formation rate of a galaxy and the strength of gravitational perturbations. We also find that the far-IR colors depend on whether a source is isolated or interacting. Finally, we discuss the intrinsic difference between and evolution expectations for the bright IRAS galaxies and the control sample, as well as the relationship between starbursting and active galaxies.
Noise pollution in intensive care units: a systematic review article

Introduction: Noise pollution in hospital wards can arise from a wide range of sources including medical devices, air-conditioning systems and conversations among the staffs. Noise in intensive care units (ICUs) can disrupt patients’ sleep pattern and may have a negative impact on cognitive performance. Material and methods: In this review article, we searched through PubMed and Google Scholar, using [noise and (ICU or “intensive care unit”)] as keyword to find studies related to noise pollution in ICUs. In total, 250 studies were found among which 35 articles were included. Results: The majority of the reviewed studies showed that noise pollution levels were higher in ICUs than the level recommend by The United States Environmental Protection Agency and World Health Organization. Noise pollution was mostly caused by human activity and operating equipments in ICUs and other hospital wards. Conclusion: As the results indicated, identifying, monitoring and controlling noise sources, as well as educating the hospital staffs about the negative effects of noise on patients’ health, can be highly effective in reducing noise pollution.
Allocation and Taxation in Uncommitted Societies

We analyze the properties of credible equilibria in dynamic settings with privately informed agents, capital accumulation and a lack of societal commitment. We show that a lack of commitment tilts the social tradeoff between equality and incentives towards the former and has ambiguous implications for capital accumulation. We isolate forces that promote and retard capital accumulation in these settings, derive the pattern of intertemporal wedges that characterize optimal credible allocations and show that these allocations solve the problem of a committed pseudo-planner with perturbed preferences and production possibilities. We obtain implementations of credible societal optima that feature progressive taxes on capital. Finally, we derive asset pricing implications of no commitment-private information models.
Ergodic capacity analysis of downlink distributed antenna systems using stochastic geometry

This paper studies the ergodic capacity of a multicell distributed antenna system (DAS), where remote antenna ports are spread within each cell to cooperatively transmit to user terminals. Unlike most prior studies which assume the antenna ports to be deployed at fixed locations, this paper assumes the antenna ports to be distributed as a spatial Poisson point process (PPP) to account for the fact that in practice the antenna ports are randomly placed to cover wherever the dead spots are. We first model DAS within each cell as a downlink multiple-input single-output (MISO) channel with per-antenna power constraint while accounting for inter-cell (inter-cluster) interference. Two DAS layouts are considered: the “regular” layout where the antenna ports are randomly deployed within regular cellular boundary to serve a given user, and the “user-centric” layout where the antenna ports are distributed over a wide area and the users choose the surrounding antenna ports to form a “virtual cell” as its own serving antenna subset. Using the tool of stochastic geometry, we analytically derive efficiently computable ergodic capacity expressions for the two layouts of DAS. Using these expressions, the cell-edge capacity of DAS under the regular layout is shown to be upper-bounded by α/2, where α is the pathloss exponent. Numerical results show that the proposed analytical model can accurately model the first layout, and can well approximate the second layout when the serving radius of users is not large. Compared to the traditional cellular system where all antennas are co-located at the cell center, DAS has better cell-edge performance. Further, the user-centric DAS has higher capacity than the DAS under regular layout.
An investigation of Generation Y travellers’ beliefs and attitudes towards green hotel practices: a view from active and passive green Generation Y travellers

Abstract Generation Y, also known as Millennial, have a reputation for being more environmentally conscious than the Baby Boomers and Generation Xers who preceded them. However, the literature on hospitality and tourism has not discussed Generation Y’s changing beliefs and attitudes towards sustainability and encompassing their points of view about lodging green operations, even though millennial travellers will be a dominant customer segment in the hotel industry for the next 20 years. This study identified heterogeneous groups among members of Generation Yers who hold similar beliefs and attitudes towards the environment and examined the green hotel practices they seek when travelling. A questionnaire survey was developed and administered in New York, Florida and Michigan. Using 318 samples, this study categorized millennial green travellers as active or passive, based on their beliefs and attitudes towards green initiatives. The results indicated that to Generation Y travellers in general, green hotels should have recycling and disposal programmes. t-Test results also exhibit significant differences in the green hotel practice factors expected by active and passive green millennial travellers. To active green travellers, green certification and visible green advertisement are important factors when they stay in a green hotel. The implications of the study are discussed.
Antigen recognition by H-2-restricted cytolytic T lymphocytes is not mediated by two independent receptors

Detergent-solubilized murine cytolytic T lymphocytes (CTL) clones were incorporated into Sendai virus-containing synthetic liposomes. When these liposomes were then fused with other CTL clones possessing a different non-cross-reacting specificity, the fusion products were observed to lyse target cells recognized by both parental CTL clones. This method was then used with two H-2-restricted CTL clones of different, non-cross-reacting specificities (anti-H-2b-H-Y or anti-H-2b Moloney leukemia virus). Once again, the fusion products were found to be lytic against both target cells recognized by the parental clones, but in no instance was there any observable lysis of target cells bearing the same nominal antigen in the context of different H-2 molecules. These results provide strong evidence that antigen recognition by H-2-restricted CTL is not mediated by two independent antigen receptors.
Immunogenicity and safety of the 10-valent pneumococcal nontypeable Haemophilus influenzae protein D conjugate vaccine (PHiD-CV) co-administered with DTPa vaccine in Japanese children: A randomized, controlled study

This phase III, randomized, open-label, multicenter study (NCT01027845) conducted in Japan assessed the immunogenicity, safety, and reactogenicity of 10-valent pneumococcal nontypeable Haemophilus influenzae protein D conjugate vaccine (PHiD-CV, given intramuscularly) co-administered with diphtheria-tetanus-acellular pertussis vaccine (DTPa, given subcutaneously). Infants (N=360 ) were randomized (2:1) to receive either PHiD-CV and DTPa (PHiD-CV group) or DTPa alone (control group) as 3-dose primary vaccination (3–4–5 months of age) and booster vaccination (17–19 months of age). Immune responses were measured before and one month after primary/booster vaccination and adverse events (AEs) were recorded. Post-primary immune responses were non-inferior to those in pivotal/efficacy European or Latin American pneumococcal protein D-conjugate vaccine studies. For each PHiD-CV serotype, at least 92.6% of infants post-primary vaccination and at least 97.7% of children post-booster had pneumococcal antibody concentrations ≥0.2 μg/ml, and at least 95.4% post-primary and at least 98.1% post-booster had opsonophagocytic activity (OPA) titers ≥8 . Geometric mean antibody concentrations and OPA titers (except OPA titer for 6B) were higher post-booster than post-priming for each serotype. All PHiD-CV-vaccinated children had anti-protein D antibody concentrations ≥100 EL.U/ml one month post-primary/booster vaccination and all were seroprotected/seropositive against each DTPa antigen. Redness and irritability were the most common solicited AEs in both groups. Incidences of unsolicited AEs were comparable between groups. Serious AEs were reported for 47 children (28 in PHiD-CV group); none were assessed as vaccine-related. In conclusion, PHiD-CV induced robust immune responses and was well tolerated when co-administered with DTPa in a 3-dose priming plus booster regimen to Japanese children.
Prevalence and risk factors of contact dermatitis among clothing manufacturing employees in Beijing

Abstract Little is known about the epidemiology of contact dermatitis (CD) in the Chinese clothing industry. This study aimed to investigate the prevalence and some risk factors of contact dermatitis among clothing manufacturing employees in Beijing. This cross-sectional study was conducted by interview using self-administered questionnaires and skin examination between May and August in 2016. Five-hundred twenty-nine employees who had worked at sewing, ironing, and as managers at 12 clothing manufacturing factories were studied. The overall 1-year prevalence of CD among the clothing employees was 28.5% (151/529 employees), with significantly higher prevalence among ironing workers (50%) and sewers (31.7%) compared with managers (12.7%; P < 0.001, n = 529). A significant association was noticed between the 1-year prevalence of CD and types of occupation (sewers and ironing workers versus managers, respectively), exposure to garment materials (leather and feather), dry skin, allergic rhinitis, age, and smoking. Among employees in Chinese clothing industry, sewers and ironing workers had a higher 1-year prevalence of CD than managers. It is noteworthy that exposure to leather and feather materials and the types of manual work are associated with CD, as well as dry skin and allergic rhinitis.
COMPUTER PERCEPTIONS OF SECONDARY SCHOOL TEACHERS AND IMPACTING DEMOGRAPHICS: A TURKISH PERSPECTIVE

Technology use in education is largely influenced by external environmental and personal teacher factors. Adding a Turkish perspective, the purpose of the present study was to explore secondary school teachers’ perceptions of computers and influencing demographics characteristics. Cross-sectional survey methodology was employed in three secondary high schools known for their educational and technological eminence. A total of 130 secondary school teachers participated. Teacher perceptions were defined to include computer attitudes, technological affinity, technological aversion, and confidence and comfort. The survey instrument measured these dimensions in four scales. General Linear Model findings illustrated effects of computer experience and training, gender, teaching field and Internet connection availability on perceptions. Ownership of personal computer appeared to be an important predictor of higher level computer experience and training, and consequently, more positive attitudes and higher confidence and comfort. Implications address pre- and inservice teacher development programs. Further research recommendations are made.
Disks around the Young Stars TW Hydrae and HD 100546 Imaged at 3.4 Millimeters with the Australia Telescope Compact Array

We present observations of the young stars TW Hya and HD 100546 made with the Australia Telescope Compact Array at 89 GHz with ~2'' resolution and ~3 mJy continuum sensitivity. Compact thermal dust continuum emission is detected from disks surrounding both stars. HD 100546 also shows hints of extended emission, presumably a residual protostellar envelope, which is also visible in scattered light at optical wavelengths. For TW Hya, HCO+ J = 1-0 line emission from the circumstellar disk is detected and spatially resolved. The observed size and intensity are in good agreement with model calculations based on an irradiated disk with substantial depletions derived previously from single-dish observations of higher J HCO+ transitions.
Topographical organization of the motoneuron pools that innervate the muscles of the pinna of the cat

The topographical organization of the 22 motoneuron pools that innervate the pinna muscles of the cat was examined by injecting the B‐subunit of cholera toxin conjugated to horseradish peroxidase into individual muscles. All 22 pools are found in the facial nucleus, organized as rostro‐caudally oriented columns, and arranged according to the action of the muscles they innervate. Pools innervating muscles that pull the pinna dorsally are located in the dorsal two thirds of the medio‐dorsal subdivision, and those innervating muscles that pull the pinna ventrally are located in the ventral one half of the nucleus. Motoneurons innervating muscles that pull the pinna cranially are located laterally, those that pull the pinna caudally are located medio‐ventrally, and those that change the shape of the pinna are located along the entire dorso‐ventral extent in the center of the medio‐dorsal subdivision. This topographical layout is consistent with the somatotopic organization of the entire facial nucleus as demonstrated in a variety of species. © 1995 Wiley‐Liss, Inc.
A Defect in Tryptophan Catabolism Impairs Tolerance in Nonobese Diabetic Mice

The predisposition of nonobese diabetic (NOD) mice to develop autoimmunity reflects deficiencies in both peripheral and central tolerance. Several defects have been described in these mice, among which aberrant antigen-presenting cell function and peroxynitrite formation. Prediabetes and diabetes in NOD mice have been targeted with different outcomes by a variety of immunotherapies, including interferon (IFN)-γ. This cytokine may be instrumental in specific forms of tolerance by virtue of its ability to activate immunosuppressive tryptophan catabolism. Here, we provide evidence that IFN-γ fails to induce tolerizing properties in dendritic cells from highly susceptible female mice early in prediabetes. This effect is associated with impaired tryptophan catabolism, is related to transient blockade of the Stat1 pathway of intracellular signaling by IFN-γ, and is caused by peroxynitrite production. However, the use of a peroxynitrite inhibitor can rescue tryptophan catabolism and tolerance in those mice. This is the first report of an experimental autoimmune disease in which defective tolerance is causally linked to impaired tryptophan catabolism.
Infotainment across access devices: the perceptual impact of multimedia QoS

The introduction of multimedia on pervasive and mobile communication devices raises a number of perceptual quality issues. However, limited work has been done examining the 3-way interaction between use of equipment, user perceptual quality and quality of service. Our work measures user perceptual quality with the quality of preception (QoP) metrics which comprises levels of informational transfer (objective) and user satisfaction (subjective) when users are presented with multimedia video clips at three different frame rates, using four different display devices. Finally, our results will show that variation in frame-rate does not impact a user's level of information assimilation (IA), however, does impact a users' perception of multimedia video 'quality'.
