Technical note: Evaluation of the simultaneous measurements of mesospheric OH, HO2, and O3 under a photochemical equilibrium assumption – a statistical approach

Abstract. This Technical Note presents a statistical approach to evaluating simultaneous measurements of several atmospheric components under the assumption of photochemical equilibrium. We consider simultaneous measurements of OH, HO2, and O3 at the altitudes of the mesosphere as a specific example and their daytime photochemical equilibrium as an evaluating relationship. A simplified algebraic equation relating local concentrations of these components in the 50–100 km altitude range has been derived. The parameters of the equation are temperature, neutral density, local zenith angle, and the rates of eight reactions. We have performed a one-year simulation of the mesosphere and lower thermosphere using a 3-D chemical-transport model. The simulation shows that the discrepancy between the calculated evolution of the components and the equilibrium value given by the equation does not exceed 3–4 % in the full range of altitudes independent of season or latitude. We have developed a statistical Bayesian evaluation technique for simultaneous measurements of OH, HO2, and O3 based on the equilibrium equation taking into account the measurement error. The first results of the application of the technique to MLS/Aura data (Microwave Limb Sounder) are presented in this Technical Note. It has been found that the satellite data of the HO2 distribution regularly demonstrate lower altitudes of this component's mesospheric maximum. This has also been confirmed by model HO2 distributions and comparison with offline retrieval of HO2 from the daily zonal means MLS radiance.
Survey Approaches In Green Supply Chain Management Research: An Analysis

Survey is an approved method that has been used by researchers for many years ago. The effectiveness of the method cannot be denied and until today, it is still the best method to identify a population perspective on the particular thing or anything that related to the purpose of a study. The aim of this paper is to examine the extent of the survey approaches in green supply chain management (GSCM) research. The findings show that GSCM survey-based research is mainly conducted in Asian countries regions which focused on the GSCM practice and performance. Postal survey is the most preferred in data collection as well as survey are also distributed in workshops. Analysis methods such structural equation modeling (SEM), conformity factor analysis (CFA), non-parametric test, correlation test, regression analysis, and ANOVA were selected to test the researches hypotheses while SPSS and AMOS are the favourite software that used for the analysis.

How are public sector organizations assessing their IT investments and benefits-An understanding of issues for Benchmarking

Despite the growing IT spending by public sector organizations, evaluation of IT investments still presents a major problem for these organizations. A survey of the top 500 Australian public sector organizations and the in-depth case studies of three Australian public sector organizations were conducted. The main purpose of the study was to examine the key issues of IT investment evaluation and benefits realization in public sector organizations. The results indicated that effective deployment of appropriate IT investment evaluation methodology and benefits realization methodology are critical to the successful outcomes for IT project. A number of key IT evaluation issues were also identified: user satisfaction, top management support, change management, and user involvement.
Theoretical Study of Polyethylene Crystallization Using Modified Weighted Density Approximation (MWDA)

In this article, the crystallization of polyethylene is investigated by the modified weighted density approximation. Also, a direct correlation function of polyethylene based on the RISM theory is used. The free energy of a polyethylene is calculated using the density functional theory. The crystallization and also the solid and liquid densities of polyethylene are calculated and compared with the PRISM simulations and experimental results. It is shown that the results obtained by modified weighted density approximation (MWDA) are in a better agreement with the experimental results rather than the PRISM simulations.
INCREASING INCIDENCE OF MULTIDRUG RESISTANCE Klebsiella pneumoniae INFECTIONS IN HOSPITAL AND COMMUNITY SETTINGS

Introduction- Klebsiella pneumoniae have been identified as an important common pathogen for nosocomial pneumonia (7 to 14% of all cases), septicaemia (4 to 15% of all cases), wound infections (2 to 4% of all cases), neonatal septicaemia (3 to 30% of all cases). It also causes bacteremia and hepatic infections and have been isolated from a number of unusual infections including endocarditis, primary gascontaining mediastinal abscess, cholecyctitis, diarrhoea, peritonitis, crepitant myonecrosis, pyomyositis, necrotizing fasciitis, osteomyelitis, meningitis. β-lactam antimicrobial agents are most common treatment option for such infections. Results and observations- 986 Clinical isolates of Klebsiella pneumonia were isolated from blood (254), urine (241), respiratory specimens (206), pus (215) and body fluids (70). Among 986 clinical isolated of K. pneumoniae 718 (72.81%) isolates were from inpatients (IPD) admitted in various wards of hospital and 268 (27.18%) were found to be out patients department (OPD). A significant difference in antimicrobial susceptibility was observed with 3rd–generation cephalosporins between hospital and community strains. Of the 986 isolates of K. pneumoniae 284 (28.80%) were confirmed as ESBLs producers by phenotypic detection methods of ESBLs. Among 284 ESBLs 236 (83.09%) were hospital isolates while 48 (16.90%) were from community settings. Among 986 K. pneumoniae isolates 34 (3.44%) strains showed production of KPCs by phenotypic detection methods of KPCs. Out of 34 KPCs producers 26 were from hospital isolates and 8 were from community isolates. Hospital isolates were major ESBLs and KPCs producers. Conclusion- There is a serious need to accentuate on the rational use of antimicrobials and strictly adhere to the concept of the “reserve drug” to minimize the misuse of available antimicrobials. In addition regular antimicrobials susceptibility surveillance, knowledge and its application is essential to reduced current drug resistance rate in hospital as well as in community.
PM1 geochemical and mineralogical characterization using SEM-EDX to identify particle origin - Agri Valley pilot area (Basilicata, southern Italy)

Abstract. A PM1 geochemical and mineralogical study using Scanning Electron Microscopy (SEM) was performed on a pilot site in the Agri Valley which is close to the oil pre-treatment plant (C.O.V.A) of Europe's largest on-shore hydrocarbon reservoir. The study identified PM1 geochemical and mineralogical characters in the period before, during and immediately after a burning torch flare event. The finer fraction (DFe μm ) consisted mainly of secondary particles and soot. In the coarser fraction (DFe ≥ 0.7 μm ), natural particles originating from crustal erosion and soot were abundant. Fine quartz particles and lower Al / Si ratios are markers for desert dust origin, proving that a Saharan dust episode which occurred during the observation period played a significant role in supplying geogenic aerosol components to the PM1. Largest amounts of ≥ 0.7 μm fraction particles observed on the day of flare event may be due to a greater supply of Saharan geogenic particles. Soot had been significantly increasing long before the flare event, suggesting that this increase is also related to other causes, although we cannot exclude a contribution from flaring. S-rich aerosol consisted mainly of mixed particles originating from deposition and heterogeneous nucleation of secondary sulfates on mineral dust. Only-S particles were identified in the ≥ 0.7 μm fraction following the flare event. These particles may be indicators of larger amounts of sulphur in the atmosphere.

El objetivo de este articulo es analizar el impacto de las habilidades de los recursos humanos en la calidad obtenida en el proceso de produccion, la flexibilidad y el desempeno economico de la cadena de suministro del vino en La Rioja (Espana). Estos elementos fueron analizados como variables latentes, en las que se integraron 15 variables observadas. Asimismo, seis hipotesis fueron planteadas para relacionar estas variables en un modelo de ecuaciones estructurales, y fueron probadas usando minimos cuadrados parciales en el software WarpPLS v.5. Los datos fueron obtenidos de 64 empresas vitivinicolas ubicadas en La Rioja, Espana. Los resultados indicaron que las capacidades de los recursos humanos tienen un impacto directo y positivo en la flexibilidad y la calidad de la cadena de suministro, pero no en el desempeno economico de la misma; sin embargo, el efecto indirecto es obtenido a traves de la calidad y la flexibilidad.
Microseismic Monitoring of Open Pit Slopes

slope can add significant value. Recent technological advances have enabled the routine use of this technique, yielding three-dimensional quantitative information about the state of the slope. A simple numerical model has been constructed of an open pit slope and the results are discussed in light of the fact that recorded seismic events can be located some hundreds of meters behind the slope surface. Seismic movements of known geological structures within the slope can be recorded and potentially used to assess trends in relative stability. It should be possible to indicate previously unknown structures using microseismic data, which may then be confirmed by other geotechnical techniques. The effects of complex geology and geometry on recorded seismic data have been studied and a composite focal mechanism method has been used to constrain possible fault plane orientations. Appropriate source spectral models for open pit seismic events have been discussed. Two case studies show that surface movements inferred from microseismic data enjoy a close spatial correlation with actual surface movements, with an advance indication of some 30-45 days. The paper shows that carefully analysed microseismic data from open pit slopes can be used to gain greater insight into the effects of mining and subsequently can result in more accurate assessments of slope stability.

Mite Fauna (Arachnida: Acari) on Peach Cultivars in Presidente Prudente, São Paulo, Brazil

This study aimed to determine the mite diversity, population dynamics and to conduct a fauna analysis in plantations from four peach varieties established in the municipality of Presidente Prudente, SP, Brazil. The mite fauna from ‘Joia 4’, ‘Ouromel 3’, ‘Regis’ and ‘Rei da conserva’ cultivars over the rootstock Okinawa were determined from December 2002 to February 2006. Samples composed by 72 leaves were collected fortnightly from upper, middle and lower third of each tree and four trees per cultivar. A total of 3,084 mites were recovered during the experiment, with the following distribution: 2,638 phytophagous, 373 predators and 73 of unknown feeding habit. The mites recovered were related to 18 species from 12 mite families. Aculus fockeui (Eriophyidae) occurred sporadically, not causing symptoms on the canopy. Euseius citrifoluis was the most abundant species among the Phytoseiidae, with predominance on cultivar ‘Regis’.
Event-based optical-flow for autonomous driving using synthetic sensory data from an open-source simulator

Event-based vision is a quickly developing field. Many novel event-based approaches to existing problems have been developed in recent years and demonstrated their capability for improvements with respect to conventional frame-based vision. Due to the novelty of the field, it is still difficult to apply some these approaches to scenarios in the real world. This new vision paradigm is interesting for the application in the autonomous driving domain, as the properties of sensors such as the Dynamic Vision Sensor (DVS) suggest to solve some remaining challenges in this field. In this work, the difficulty to assess real world data is reduced by formulating a synthetic data source. The DVS data is generated from frames that are rendered in a driving simulation. An event-based vision approach is implemented to process the resulting stream of events. In a first processing stage, the optical flow induced by the driving motion is estimated. These results are used to attempt an event-driven approach to collision avoidance. Although the goal of estimating the time to contact to an imminent collision with an obstacle is not achieved, the work in this thesis gives insights into challenges of both optical flow estimation and inherent to the driving domain. The implemented emulator, that generates synthetic events, demonstrates that DVS data can be obtained synthetically, to be used for development in the field of event-based vision.
Thennadil, Suresh N. and Dewar, Mark and Herdsman, Craig and Nordon, Alison and Becker, Edo (2018) Automated weighted outlier detection

In the chemical and petrochemical industries, spectroscopy-based online analysers are becoming common for process monitoring and control applications. A significant challenge in using these analysers as part of process monitoring and control loops is the large amount of personnel time required for calibration and maintenance of models which involve decision inputs such as whether an observation is an outlier, the number of latent variables in a model, type of pre-processing and when a calibration model has to be updated. Since no one measure works well for all applications, supervision by the process data analyst is required which invariably involves some level of subjectivity. In this paper, we focus on the detection of multivariate outliers in a calibration set. We propose a method which combines multiple outlier detection techniques to identify a set of outlying observations without operator input. Apart from the overall methodology, this work introduces several novelties. The system uses partial least squares (PLS) instead of principal component analysis (PCA) which is normally used for detecting multivariate outliers. A simple modification to the Mahalanobis distance was also proposed which appears to be more sensitive to outliers than the conventional Mahalanobis distance. The methodology also introduces the concept of a desirability function to enable automatic decision making based on multiple statistical Automated Outlier Detection Page 2 of 34 measures for outlier detection. The methodology is demonstrated using Raman spectroscopy data collected from an industrial distillation process.
Mass spectrometry imaging of the capsaicin localization in the capsicum fruits

We succeeded in performing mass spectrometry imaging (MSI) of the localization of capsaicin in cross-sections of the capsicum fruits at a resolution of 250 µm using matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry. Post source decay of protonated capsaicin ion revealed structural information of the corresponding acid amide of vanillylamide and C 9 chain fatty acid. MALDI-TOF-MSI confirmed that localization of capsaicin in the placenta is higher than that in the pericarp. In addition, it revealed no localization of capsaicin in seed and the higher localization of capsaicin at placenta surface compared with that in the internal region. A quantitative difference was detected between localizations of capsaicin at placenta, pericarp and seed in the capsicum fruits. This imaging approach is a promising technique for rapid quality evaluation general food as well as health food and identification of medicinal capsaicin in plant tissues.
External dependence of the organization: Causes and effective response

Organizations can manage external dependence by establishing favorable external linkages and introducing changes in organizational design. This study analyzes from a theo-retical perspective how changes in technology and consumer preferences can promote a firm‘s dependence on external agents such as external firms and customers. The analysis is focused in main three objectives: first, finding a relationship between the changes in technology and the firm’s dependence on external actors. Second, to find a relationship between the changes in consumer preferences and the firm’s dependence on external actors and third, to find out the way the firm should respond to the change according to these environmental factors. The study concludes that firms with flexible organizational design are well equipped to cope with environmental changes. Firms not only need to access resources and capabilities from external organizations, but they also need to include their customer’s knowledge in product design and development process.

RESPONSE OF VENTILATION IN CASE OF 40MW AND 80MW TUNNEL-FIRE - THE CFD INVESTIGATION

The fact, that every other underground facility, as large-scale space, differs from each other in its geometric characteristics, sets always new tasks for researchers who are investigating the fluid phenomena. In this manner, we performed computationally aided investigation of new covered traffic road-communication that undergoes a part of Slovenian Capital of Ljubljana. Although still not finished - we were capable with the employed both (steady-state) RANS and (transient) LES turbulence treatment, to give a CFD-forecast for effectiveness of ventilation in events of both 40MW- and 80MW-fires.

Exchange Rate Pass-Through to Domestic Prices in Uganda: Evidence from a Structural Vector Auto-Regression (SVAR)

This paper examines the degree of exchange rate pass through to inflation in Uganda with quarterly data over the period 1999Q3 to 2012Q2 using a triangulation of well specified Vector Error Correction (VEC) and Structural Vector Auto-Regression (SVAR) models. The findings show strong and significant association between the exchange rate movements and inflation in Uganda, and that the pass-through to domestic inflation, although incomplete, is modest and persistent with a dynamic exchange rate pass-through elasticity of 0.48. This suggests that exchange rate movements remain a potentially important source of inflation in Uganda. Using variance decomposition, it is found that exchange rate shocks have a modest contribution to inflation variance, although inflation is mainly driven by own shocks especially at shorter horizons. The policy implication arising from these findings is that the monetary authority must be vigilant at exchange rate movements and focus on exchange rate interventions which stem inflation pressure from the external sector.
Morphological and genetic diversity levels of Penaeus monodon (Fabricius, 1798) populations in three coastal regions of Sri Lanka.

Morphological and genetic variations of three Penaeus monodon populations in Sri Lanka were determined using data from truss network method and partial amplification of mitochondrial control (mtC) gene region respectively. Total of 37 morphometric characters were collected from 178 individuals representing three populations (eastern, western and southern) and subjected to principal component analyses (PCA) to determine the morphological variation among three populations. Two principal components (PC) derived from PCA analysis with the accumulated variance for the two PC represented 75% of the total. The plot against first and the second principal components scores revealed great morphological similarity among three populations. For genetic analysis, a total of 600 bp DNA fragment was amplified from mtC gene region and 26 haplotypes were produced for three populations from the total of 63 samples examined. Among three populations, mean haplotype diversity (h) ranged from 0.35 (southern) to 0.92 (eastern) and nucleotide diversity (π) ranged from 0.005 (southern) to 0.025 (western). Analysis of molecular variance (AMOVA) indicated within population variation as 78.89% and among population variation as 21.11% indicating high intra-population diversity. The overall Fst value indicated significant genetic structure among three populations (Fst = 0.2111, p < 0.05). Genetic diversity levels of Sri Lankan P. monodon populations were compared with published data for this species from other geographic locations.
Adsorption of H 2 S molecule on TiO 2 / Au nanocomposites : A density functional theory study

* Corresponding Author Email: a_abbasi@azaruniv.edu The adsorption of hydrogen sulfide molecule on undoped and N-doped TiO2/Au nanocomposites was investigated by density functional theory (DFT) calculations. The results showed that the adsorption energies of H2S on the nanocomposites follow the order of 2N doped (Ti site)>N-doped (Ti site)>Undoped (Ti site). The structural properties including bond lengths, angles and adsorption energies and electronic properties in view of the projected density of states (PDOSs) and molecular orbitals (MOs) were analyzed in detail. The results indicated that the interaction between H2S molecule and N-doped TiO2/Au nanocomposite is stronger than that between H2S and undoped nanocomposite, suggesting that N-doping helps to strengthen the interaction of H2S with TiO2/Au nanocomposite. Mulliken population analysis was conducted to analyze the charge transfer between the nanocomposite and H2S molecule. Although H2S molecule has no significant interaction with undoped nanocomposite, it tends to be strongly adsorbed on the N-doped nanocomposite. The results also suggest that the two doped nitrogen atoms in TiO2 greatly strengthen the adsorption process, being a helpful procedure to help in the design and development of improved sensor devices for H2S detection.
