Fully Crystallized Silicon Nanostructured Film Prepared at Low Temperatures by Plasma-Enhanced Chemical Vapor Deposition

I studied the nanocrystalline silicon thin films by means of photoluminescent spectroscopy, Raman spectroscopy and Fourier-transformed infrared spectroscopy technique. The chemical bonding properties was studied by using the Fourier-transformed infrared spectroscopy in the range from500 cm -1 to 2300 cm -1 . Spectral peak at wave number of 1100 cm -1 is related to the Si-O-Si bonding configuration. Hydrogenation of film can be estimated by using spectral lines at 2100 cm -1 and 2080 cm -1 . The Si-O dipoles which are located into silicon film play great role because of electron affinity for oxygen. Photoluminescent (PL) properties are significant for the films which were made by using hydrogenation of silicon. Fourier-transformed infrared spectra of film’s absorption show the changes in chemicals in the film: from the oxygen incorporation into silicon to the elimination the Si-O bonding by adding the silicon tetra fluoride into electrochemical reactor, and increasing the Si-F density of bonds. The dissociation of SiF 4 molecule causes the appearance of fluorine on the film surface, but the hydrogen atoms react with fluorine and excess fluorine is removed. By increase of SiF 4 flow rate, the Si-O-Si bridges were etched by HF acid. The size effect in PL from nanocrystalline silicon film can be explained by means of statistical method. We suggested that the ƒ (x) is distribution function of crystallites in their sizes, θ( x ) is a quantum efficiency of nanocrystals. Accordingly, the quantity of emitted hydrogenizednanocrystals by band-to-band radiative transitions is important to estimate the PL linear optical response. The processing of grown hydrogeneited silicon nanocrystalline film by annealing and etching the oxides results in preparation of fully crystallized silicon film for manufacturingthe photonic devices with significant quantum yield.

The aim of this study is to explain an investigation over the potential relationships between integrator and growerinvolvement towards business performance in broiler production. The potential role of employees’ skill levels asmoderating variable between the aforementioned independent and the dependant variables are discussed. Broilersupply chain practices and its corresponding performance indicators in the form of broiler farming operations areamong the important measures in the dependant variable (business performance). Based on the extensive survey ofrelevant literatures, a research framework is then proposed. The content validity has been done by getting opinionfrom the experts, namely veterinary officers. Besides that the construct reliability is determined through value fromCronbach’s Alpha. The data obtained was satisfactory for content validity and construct validity also fit the model asproposed previously.
A NEARLY POLAR ORBIT FOR THE EXTRASOLAR HOT JUPITER WASP-79b

We report the measurement of a spin-orbit misalignment for WASP-79b, a recently discovered, bloated hot Jupiter from the Wide Angle Search for Planets (WASP) survey. Data were obtained using the CYCLOPS2 optical-fiber bundle and its simultaneous calibration system feeding the UCLES spectrograph on the Anglo-Australian Telescope. We have used the Rossiter–McLaughlin effect to determine the sky-projected spin-orbit angle to be . This result indicates a significant misalignment between the spin axis of the host star and the orbital plane of the planet—the planet being in a nearly polar orbit. WASP-79 is consistent with other stars that have Teff > 6250 K and host hot Jupiters in spin-orbit misalignment.

Mixing state of oxalic acid containing particles in the rural area of Pearl River Delta, China: implications for the formation mechanism of oxalic acid

Abstract. The formation of oxalic acid and its mixing state in atmospheric particulate matter (PM) were studied using a single-particle aerosol mass spectrometer (SPAMS) in the summer and winter of 2014 in Heshan, a supersite in the rural area of the Pearl River Delta (PRD) region in China. Oxalic-acid-containing particles accounted for 2.5 and 2.7 % in total detected ambient particles in summer and winter, respectively. Oxalic acid was measured in particles classified as elemental carbon (EC), organic carbon (OC), elemental and organic carbon (ECOC), biomass burning (BB), heavy metal (HM), secondary (Sec), sodium-potassium (NaK), and dust. Oxalic acid was found predominantly mixing with sulfate and nitrate during the whole sampling period, likely due to aqueous-phase reactions. In summer, oxalic-acid-containing particle number and ozone concentration followed a very similar trend, which may reflect the significant contribution of photochemical reactions to oxalic acid formation. The HM particles were the most abundant oxalic acid particles in summer and the diurnal variations in peak area of iron and oxalic acid show opposite trends, which suggests a possible loss of oxalic acid through the photolysis of iron oxalato-complexes during the strong photochemical activity period. In wintertime, carbonaceous particles contained a substantial amount of oxalic acid as well as abundant carbon clusters and BB markers. The general existence of nitric acid in oxalic-acid-containing particles indicates an acidic environment during the formation process of oxalic acid. The peak areas of nitrate, sulfate and oxalic had similar temporal change in the carbonaceous type oxalic acid particles, and the organosulfate-containing oxalic acid particles correlated well with total oxalic acid particles during the haze episode, which suggests that the formation of oxalic acid is closely associated with the oxidation of organic precursors in the aqueous phase.
Understanding the divide between the theory and practice of organisational change

This paper reviews the different ways that academics and practitioners write about and discuss change management, to develop an understanding of whether there is a divide between the theory and practice of change management. This research used scientometric research techniques to compare three corpora: one based on the most cited research in the general management literature on change management; one based on the most cited research in specialist change management journals; and one based on interviews with practising change managers. It was found that the general management literature emphasised an abstract understanding of knowledge management and the learning organisation, while the change management literature focused more on issues associated with value, culture and social identity. The practitioners emphasised issues at the individual, project and team levels, the need for the effective use of targeted communication to achieve organisational change objectives, and the value of rapidly identifying key drivers in a new context. This research found significant differences between these three corpora, which lends support to other researchers’ claims of a divide between theory and practice in change management.
Estimating Household Willingness to Pay for Improved Solid Waste Management: A Case Study of Thu Dau Mot City, Binh Duong

The main objective of this paper is to investigate the household willingness to pay (WTP) for improved solid waste management in Thu Dau Mot city, Binh Duong by using Dichotomons choice Contingent Valuation Method. A questionnaire was designed to draw a sample of 330 respondents for the study. The results show that mean household willingness to pay for solid waste management system in Thu Dau Mot is about 24 thousand VND/ month/ household, higher than the current fee (20 thousand VND month/ household). The paper used a logistic regression to establish the factor affecting to the household willingness to pay for solid waste management system. The logit results show that those with a higher income and more educated is willing to pay more for improvement in management of their solid waste. Also, more environmental aware the person the more they are willing to pay. Moreover, females are less likely to give a positive response to WTP compare to male.
Growth promotion of the rice genotypes by pgprs isolated from rice rhizosphere

Plant growth promoting rhizobacteria (PGPRs) improve growth of the host plants in a variety of ways. For this reason five bacterial strains isolated form the rice rhizospheric soil (B 15, B 17, B 19, BN 17 and BN 30) and three standard PGPR strains (viz. Pseudomonas putida, Pseudomonasfluorescens and Azospirillum lipoferum) were tested for plant growth promotion when applied to the rice plants as seedling treatments. The experiment was conducted for two rainy seasons of the years 2010 and 2011. Rice plants inoculated with the bacterial isolates recorded an improved plant growth and higher photosynthetic capacity signified by the higher chlorophyll content. Root and shoot dry mass was also found to be increased in the inoculated plants. Besides these iron and zinc content of the treated rice plants was also found to be higher in comparison with the uninoculated control plants. Hence, it can be concluded that application of PGPR has immense potential to be used as agricultural crop inoculants as they promote plant growth as well as improve the health and yield of the plants.
Testing Purchasing Power Parity in Romania using standard unit root tests, with one structural break and cointegration analysis

In this paper we aim to analyze the long-run validity of the Purchasing Power Parity (PPP) hypothesis for the Romanian exchange rate. Our goal is achieved using Zivot-Andrews test with one structural break in order to identify changes in real exchange rate compared with traditional tests like Augmented Dickey-Fuller and Phillips-Perron and cointegration analysis in order to identify the long-run relationship between exchange rate and domestic and foreign prices. Real exchange rate stationarity implies that a shock it is absorbed in time and PPP holds in long-run. If nominal exchange rate and prince indices are non-stationary we verify if the variables are cointegrated as PPP weak form and symmetry and proportionality conditions as PPP strong form. We identify evidence of cointegration for all three models, but we don’t find any evidence to support symmetry and proportionality condition for PPP strong form case. Also, we use three different price indices: consumer price index, consumer price index without regulated prices and industrial producer price index in order to identify which indices is more relevant for our analysis. The monthly data cover the 2001M01-2011M09 period. The empirical analysis provided mixed results depending on the used price index and methodology.
DISTANCE MEASUREMENT MODEL BASED ON RSSI LOCALIZATION TECHINQUE IN WIRELESS SENSOR NETWORKS

N ode localization is one of the basic problems in wireless sensor networks.The localization method based on RSSI measurement is studied in this paper. Because the RF signals are affected by the environment, the exact distance between the nodes cannot obtain by RSSI measurement.The parameters of measurement model are determined by anchor nodes, and further correct the measurement data, which can reduce the measurement. The improved RSSI measurement can improve the accuracy of the unknown nodes localization.
Investigation of the Air Pollution Event in Beijing-Tianjin-Hebei Region in December 2016 Using WRF-Chem

The online coupled weather research and forecasting model with chemistry (WRF-Chem) was used to investigate an air pollution event during December 2016 in Beijing-Tianjin-Hebei urban agglomeration. Evaluation indicates that WRF-Chem captured the main weather conditions and pollutant distribution in this event. The primary meteorological drivers of air pollution formation were stationary atmospheric flows in both vertical and horizontal directions. High relative humidity and a strong temperature inversion accelerated event formation. In the shallow temperature inversion layer, aerosol particles were strongly confined near the surface, producing high surface contaminant concentrations. In addition, based on a normal experiment, three sensitivity experiments were constructed by adding hypothetical terrain (HT) of 400, 300, and 200 meters, over the region 115°E, 38.8°N to 117.54°E, 38.8°N. The results indicate that pollutants were diffused and transported below 400 meters, and the pollutant amounts concentrated south of the HT because of the HT blocking effect. Nevertheless, because there were less total contaminants north of the HT in the normal run, there was a slight decrease in pollutants north of the HT. There were some increases in pollution north of the HT because of local emissions, which were obstructed by the HT. The higher the HT, the stronger the blocking effect.
An enhanced high performance combinational fault simulator using two-way parallelism

A combinational fault simulator using two-way parallelism and a number of refinements to reduce memory usage is presented. The results show the approach to be generally superior to the basic parallel patterns single fault propagation (PPSFP) algorithm. One of the refinements, processing to encourage the sharing of fault machine indices by independent faults, appears to require substantially more processing time than it saves during simulation. The remaining preprocessing steps are comparable to those used for basic PPSFP, and are highly justified by their run-time savings. The concept of adjusting the parallelism factor to account for increasingly random-resistant faults seems to work quite well. <<ETX>>

Rotating Unruh-DeWitt Detector in Minkowski Vacuum

Response of a circularly rotating Unruh-DeWitt detector to the Minkowski vacuum is investigated. What the detector observes depends on the surface (three volume) to define it by the Hamiltonian. Detectors in the past literature were defined on a surface of a constant Minkowski time, and this is the reason why rotating detectors investigated so far resister particles. No particle is detected by a detector defined by the Hamiltonian on a surface normal to the detector's orbit, in agreement with the global analysis of vacua. A detector with drift motion superposed on the linear acceleration is also examined, to find the same effect. c
Open Source Licensing and Scattering Opportunism in Software Standards

Despite their beneficial influence on interoperability and markets, problems of detrimental opportunism occur with technology standards, including standards implemented in software, which this Article calls "Software Standards. " Inspired by new perspectives on the study of semicommons in the history of real property, this Article contemplates the substitutability of free and open source software ("FOSS") for traditional standard-setting approaches. Standards are analogous to semicommons, where public and private use interact, raising the possibility of opportunistic influence on the Software Standard to increase private gain at the expense of the public benefit in a more uniform standard. With its source code disclosure requirement, FOSS shifts and dampens this opportunism, although various limits influence the reach of its effect. The political economy around a standard will express itself differently under a FOSS implementation, and clearing intellectual property rights in the standard is no more certain than under the traditional standard-setting approach.
Mediating relationship of differential products in understanding integration in introductory physics

In the context of introductory physics, we study student conceptual understanding of differentials, differential products, and integrals and possible pathways to understanding these quantities. We developed a multiple choice conceptual assessment employing a variety of physical contexts probing physical understanding of these three quantities and administered the instrument to over 1000 students in first and second semester introductory physics courses. Using a regression-based mediation analysis with conceptual understanding of integration as the dependent variable, we found evidence consistent with a simple mediation model: the relationship between differentials scores and integral scores may be mediated by the understanding of differential products. The indirect effect (a quantifiable metric of mediation) was estimated as ab 1⁄4 0.29, 95% CI [0.25, 0.33] for N 1⁄4 1102 Physics 1 students, and ab 1⁄4 0.27, 95% CI [0.14, 0.48] for N 1⁄4 65 Physics 2 students. We also find evidence that the physical context of the questions can be an important factor. These results imply that for introductory physics courses, instructional emphasis first on differentials then on differential products in a variety of contexts may in turn promote better integral understanding.
LINKING THE LOCAL CLIMATE ZONES AND LAND SURFACE TEMPERATURE TO INVESTIGATE THE SURFACE URBAN HEAT ISLAND , A CASE STUDY OF SAN ANTONIO , TEXAS ,

The Local Climate Zones (LCZs) concept was initiated in 2012 to improve the documentation of Urban Heat Island (UHI) observations. Despite the indispensable role and initial aim of LCZs concept in metadata reporting for atmospheric UHI research, its role in surface UHI investigation also needs to be emphasized. This study incorporated LCZs concept to study surface UHI effect for San Antonio, Texas. LCZ map was developed by a GIS-based LCZs classification scheme with the aid of airborne Lidar dataset and other freely available GIS data. Then, the summer LST was calculated based Landsat imagery, which was used to analyse the relations between LST and LCZs and the statistical significance of the differences of LST among the typical LCZs, in order to test if LCZs are able to efficiently facilitate SUHI investigation. The linkage of LCZs and land surface temperature (LST) indicated that the LCZs mapping can be used to compare and investigate the SUHI. Most of the pairs of LCZs illustrated significant differences in average LSTs with considerable significance. The intra-urban temperature comparison among different urban classes contributes to investigate the influence of heterogeneous urban morphology on local climate formation.

Dynamical obstruction to the existence of continuous sub-actions for interval maps with regularly varying property

In ergodic optimization theory, the existence of sub-actions is an important tool in the study of the so-called optimizing measures. For transformations with regularly varying property, we highlight a class of moduli of continuity which is not compatible with the existence of continuous sub-actions. Our result relies fundamentally on the local behavior of the dynamics near a fixed point and applies to interval maps that are expanding outside an indifferent fixed point, including Manneville-Pomeau and Farey maps.
Comparing Models GRM, Refraction Tomography and Neural Network to Analyze Shallow Landslide

Detailed investigations of landslides are essential to understand fundamental landslide mechanisms. Seismic refraction method has been proven as a useful geophysical tool for investigating shallow landslides. The objective of this study is to introduce a new workflow using neural network in analyzing seismic refraction data and to compare the result with some methods; that are general reciprocal method (GRM) and refraction tomography. The GRM is effective when the velocity structure is relatively simple and refractors are gently dipping. Refraction tomography is capable of modeling the complex velocity structures of landslides. Neural network is found to be more potential in application especially in time consuming and complicated numerical methods. Neural network seem to have the ability to establish a relationship between an input and output space for mapping seismic velocity. Therefore, we made a preliminary attempt to evaluate the applicability of neural network to determine velocity and elevation of subsurface synthetic models corresponding to arrival times. The training and testing process of the neural network is successfully accomplished using the synthetic data. Furthermore, we evaluated the neural network using observed data. The result of the evaluation indicates that the neural network can compute velocity and elevation corresponding to arrival times. The similarity of those models shows the success of neural network as a new alternative in seismic refraction data interpretation.
