Indirect Prediction of Welding Fume Diffusion inside a Room Using Computational Fluid Dynamics

Welding is an important and widely used process in the manufacturing and maintenance of various works involving metals and alloys. While welding has broad applications, the welding fume generated during the process has impacts on workers’ health, which needs to be addressed. One of the major steps that can be undertaken to take care of this issue is the use of ventilation, which requires knowledge of characteristics and dispersion of the welding fume in the workers’ breathing zone. It is difficult to assess welding fume dispersion from manual measurement due to numerous welding processes and sufficient data requirement. Numerical prediction of welding fume is dubious due to several errors. This paper considers the use of numerically predicted CO2 concentrations to indirectly predict welding fume distribution in workshops. This is based on the assumption that if the particles are sufficiently small size, they follow the diffusion pattern of gases. Experiments are carried out in a room with an opening and a welding fume generation system for measurement of CO2 and fume diffusion. The results show high possibility of predicting welding fume concentration based on Computational Fluid Dynamics (CFD) simulated CO2 concentration with a correlation coefficient of 0.74.
A gender-specific analysis of suicide methods in deliberate self-harm

Background: Deliberate self-harm (DSH) is a major public health concern. Gender differences in suicide methods are a controversial realm with various regional and cultural variations. This study compared and assessed the methods used in DSH attempters as undertaken by men and women, and investigated the possible role of gender and other clinical variables in the selection of suicide method. Materials and Methods: Two hundred subjects fulfilling the inclusion and exclusion criteria were recruited in the study. The sociodemographic details were recorded in the semi-structured pro forma. Detailed assessment of psychiatric morbidity and DSH was done by clinical interview and validated by Mini International Neuropsychiatric Interview-Plus 5.0 and Beck Suicide Intent Scale. Data were analyzed using SAS version 9.2 and SPSS version 17.0. The sample was disaggregated by gender to compare the known correlates of suicide risk on the two most common methods of suicide – poison consumption and drug overdose using multivariate analyses. Results: The analysis revealed that majority of the attempters were in the age group of 11–40 years (91%). Females (63%) outnumbered males (37%); poisoning was the most common type of method (50.5%), followed by drug overdose (35%). There were no statistical differences between the two genders with respect to other sociodemographic variables. Males from urban/semi-urban background (odds ratio [OR] = 4.059) and females living alone (OR = 5.723) had high odds ratio of attempting suicide by poison consumption. Females from urban/semi-urban background (P = 0.0514) and male subjects from nuclear families had an increased odds ratio (OR = 4.482) to attempt suicide by drug overdose. There were no statistical differences when the two genders were compared for other variables such as intentionality, lethality, impulsivity, and number of attempts. Conclusions: It appears that gender differences among DSH attempters appear less pronounced in the Indian setting compared to the worldwide literature on the subject. Nevertheless, the unique, gender-specific characteristics pertaining to DSH attempters in our population emphasize the need for gender-specific interventions in future clinical treatment.
A Predictive Model for the Relative Differences between Nonlinear and Equivalent-Linear Site Response Analyses

This study investigates the nonlinear amplification of ground motion in site response analysis, with the particular goal of providing guidance on the conditions for which nonlinear (NL) approaches provide results distinct from otherwise similar equivalent-linear (EL) approaches. Relative differences in spectral accelerations computed by NL and EL site response analyses are assessed for different periods using NL and EL site response simulation results by Assimaki and Li (2012) for 23 strong motion accelerograph sites in California and one downhole array site in Japan subject to 510 synthetic ground motions. Site and ground motion parameters investigated for their effect on nonlinear response include the time-averaged shear-wave velocity in the top 30 m of the soil profile (VS30), site amplification at the fundamental frequency (Amp), peak ground acceleration and peak ground velocity of incident motions (PGAin and PGVin, respectively), and estimated strain (est=PGVin/VS30). We find that the soil nonlinearity is most clearly dependent on est, with an upper-bound threshold of approximately 0.1 % identifying conditions where EL and NL results are similar. For est > 0.4 %, it is recommended that a greater weight be given to the NL approach because the spectral accelerations computed by NL and EL analyses differ by more than 30 %, particularly for short periods (T ≤ 0.55 sec). For longer periods (T ≥ 1.0 sec), the differences between spectral accelerations by nonlinear and equivalent-linear site responses are relatively small.
A new active tectonic model for the construction of the Northern Apennines mountain front near Bologna (Italy)

[1] We integrate existing and new geologic data [REtreating TRench, Extension, and Accretion Tectonics (RETREAT project)], particularly on the origin, growth, and activity of the mountain front at Bologna, Italy, into a new model that explains Apennine orogenesis in the context of a slab rollback - upper plate retreat process. The Bologna mountain front is an actively growing structure driving rock uplift ∼1 mm/year, cored by a midcrustal flat-ramp structure that accommodates ongoing shortening driven by Adria subduction at a rate of ∼2.5 mm/year. The data we use are assembled from river terraces and associated Pleistocene growth strata, geodesy including releveling surveys, reinterpretation of published reflection lines, and a new high-resolution reflection line. These data constrain a simple trishear model that inverts for blind thrust ramp depth, dip, and slip. Apennine extension is recognized both in the foreland, as high-angle normal faults and modest stretching in the carapace of the growing mountain front, and in the hinterland, with larger normal faults that accomplish some crustal thinning as the upper plate retreats. This coevolution of extension and shortening shares some notable characteristics with other basement-involved collisional orogens including the early Tertiary Laramide orogeny in the American West and the Oligocene to Miocene evolution of the Alps. We propose a possible relationship between underplating and the development of the Po as a sag basin as a Quaternary phenomenon that may also apply to past periods of Apennine deformation (Tortonian). Continued shortening on the structure beneath the Bologna mountain front represents by far the most important and underappreciated seismogenic source in the front of the northern Apennines.
Nonparametric quantile regression analysis on the price-volume relationship in China stock market

This paper adopts nonparametric quantile regression approach to empirically analyze the relationship between daily return and trading volume and the relationship between absolute return and trading volume in China stock market. The results show that both the relationship between return per se and volume and that between absolute return and volume are nonlinear. Secondly, when the trading volume is larger than a certain value, the relationship between return per se and volume is positive at the high quantile of return and negative at the low quantile of return. However, both the positive and negative relations get stronger with larger trading volume. Thirdly, the relationship between return and volume is asymmetric. Finally, the relationship between absolute return and trading volume is positive and stronger when the quantile of absolute return increases.
A Survey of Sensitive Information Hiding Techniques

This research paper contains an overview of the new and rapidly emerging research area of privacy preserving data mining. Privacy preserving in data mining has been a heart favorite topic of researchers from many years. Every organization contains sensitive data & such data is needed to be protected from the unauthorized access. This paper contains the comprehensive survey of traditional and modern privacy preserving data mining methods. Advantages and disadvantages of the existing algorithms are discussed in brief. I also propose a classification hierarchy that sets the basis for analyzing the work which has been performed in this context.
Effect of Celebrity Endorsements on Dimensions of Customer-based Brand Equity: Empirical Evidence from Indian Luxury Market

Brand equity is a brand’s incremental value due to its name. It has been long argued that brand equity must be the ultimate criterion of success in brand management because brand equity contributes both to long-term sales and long-term profits. Celebrity endorsement has gained prominence as a popular resource for marketing strategies among many firms. This research aims to empirically test the role of celebrity endorsements in the brand equity formation process. This study explored the relationship between celebrity endorsements and four dimensions of brand equity of Aaker’s (1991) brand equity model in Indian luxury products market. Data were collected through a shopping mall intercept survey of 202 respondents in the cities of Delhi, Gurgaon, Faridabad, Noida and Chandigarh. Exploratory factor analysis was used for reducing the number of scale items while regression was used to test the proposed hypotheses. The results show a positive and significant effect of celebrity endorsements on two brand equity dimensions, that is, brand awareness and brand associations, but celebrity endorsements do not have any significant influence on other two dimensions, that is, perceived quality and brand loyalty. We finally discuss the implications—both theoretical and managerial—before providing directions for future research.
A duality-type method for the design of beams

We discuss the nonconvex optimal shape design problem of minimizing the weight of a loaded beam subject to de ection constraints. We associate to it a convex minimization problem which will play the role of a dual. The algorithm we propose has a global character and iterates between the two optimization problems via a so called \resizing rule".
Observational Constraints on Varying-alpha Domain Walls

We consider the possibility that current hints of spatial variations of the fine structure constant at high redshift, based on VLT/UVES and Keck/HIRES observations, could be caused by a biased domain wall network described by a scalar field non-minimally coupled to the electromagnetic field. We show that in order to be responsible for the reported spatial variations of the fine structure constant, the fractional contribution of the domain wall network to the energy density of the Universe should be tightly constrained within the range 10 10 < w0 < 10 5 . We also show that the domain wall dynamics should be essentially frictionless, so that its characteristic scale is in the order of the Hubble radius at the present time
Validity and reliability of the International Physical Activity Questionnaire among adults in Mexico.

OBJECTIVE To determine the test-retest reliability and validity of the Spanish version of the short-form International Physical Activity Questionnaire (IPAQ) among adults in Mexico. METHODS This was a cross-sectional study of a convenience sample of 267 adult factory workers in Mexico City. Participants were 19 - 68 years of age; 48% were female. Participants wore an accelerometer for 9 consecutive days and were administered the Spanish version of the short form IPAQ on two occasions (IPAQ1 and IPAQ2, separated by 9 days). The relation and differences between moderate-to-vigorous physical activity (MVPA) measures obtained from IPAQ1, IPAQ2, and the accelerometer were determined using correlations, linear regression, and paired t-tests. RESULTS IPAQ1 and IPAQ2 measures of MVPA were significantly correlated to each other (r = 0.55, P < 0.01). However, MVPA was 44 ± 408 minutes/week lower in IPAQ1 than in IPAQ2, although this difference did not reach statistical significance (P = 0.08). The (min/week) measures from IPAQ1 and IPAQ2 were only modestly correlated with the accelerometer measures (r = 0.26 and r = 0.31, P < 0.01), and by comparison to accelerometer measures, MVPA values were higher when based on IPAQ1 (174 ± 357 min/week, P < 0.01) than for IPAQ2 (135 ± 360 min/week, P < 0.01). The percentage of participants who were classified as physically inactive according to the World Health Organization guidelines was 18.0% in IPAQ1, 25.1% in IPAQ2, and 28.2% based on the accelerometer. CONCLUSIONS Similar to what has been observed in other populations, the short form IPAQ has a modest reliability and poor validity for assessing MVPA among Mexican adults.
Promoting Fluency in English Language Learners: The Effects of a Small-Group and a One-On-One Reading Intervention

Currently, Hispanic students score significantly lower than White, non-Hispanic students in reading throughout their elementary school years. Although several evidence-based fluency techniques exist for students who speak English as a first language (e.g., Repeated Reading, Listening Passage Preview, and Phrase Drill) research has insufficiently evaluated their effects with English language learners. This study used an alternating treatments design to examine the differential effects of a one-on-one (1/1) and small group (SG) reading fluency intervention, implemented with Spanish-speaking, English language learners. Each intervention condition was also compared to a no-treatment control condition (NTC). StudentsA¢â‚¬â„¢ words read correct per minute (WCPM) served as the primary dependent measure, though standardized reading assessments and an experimenter-developed vocabulary assessment were also administered to measure student reading progress. WCPM scores were evaluated with visual analysis, standard-error of measurement (SEM) analysis, and randomization test analysis. Compared to the NTC, all students made significant WCPM gains as a result of receiving the 1/1 condition, whereas only two students significantly outperformed the NTC as a result of the SG condition. Standardized test gains and vocabulary gains were variable across students and conditions. Overall, the study offers preliminary evidence supporting two fluency-based reading interventions for Spanish-speaking, English language learners, each of which appear differentially useful depending on the time and resources available within a particular school setting.
Homogeneous Ensemble Selection through Hierarchical Clustering with a Modified Artificial Fish Swarm Algorithm

In the pattern recognition field, ensembles of classifiers have been proposed as a method to overcome the natural limitations of single classifiers, and to increase the accuracy of the system. Previous studies show that ensembles of classifiers need to have accurate classifiers that have different knowledge for the same problem. In this paper, we propose an ensemble selection technique for single layer neural networks trained by the Extreme Learning Machine algorithm based on the Artificial Fish Swarm Algorithm. The ensembles are grouped based on information on the fish population using a hierarchical cluster algorithm. Experimental results show that the proposed method achieve better generalization performance than best model produced by the modified optimization technique presented in real benchmark datasets.
CAT: the CELCT Annotation Tool

This paper presents CAT - CELCT Annotation Tool, a new general-purpose web-based tool for text annotation developed by CELCT (Center for the Evaluation of Language and Communication Technologies). The aim of CAT is to make text annotation an intuitive, easy and fast process. In particular, CAT was created to support human annotators in performing linguistic and semantic text annotation and was designed to improve productivity and reduce time spent on this task. Manual text annotation is, in fact, a time-consuming activity, and conflicts may arise with the strict deadlines annotation projects are frequently subject to. Thanks to its adaptability and user-friendly interface, CAT can positively contribute to improve time management in annotation project. Further, the tool has a number of features which make it an easy-to-use tool for many types of annotations. Even if the first prototype of CAT has been used to perform temporal and event annotation following the It-TimeML specifications, the tool is general enough to be used for annotating a broad range of linguistic and semantic phenomena. CAT is freely available for research purposes.
Acetylation-dependent regulation of essential iPS-inducing factors: a regulatory crossroad for pluripotency and tumorigenesis

Induced pluripotent stem (iPS) cells can be generated from somatic cells by coexpression of four transcription factors: Sox2, Oct4, Klf4, and c‐Myc. However, the low efficiency in generating iPS cells and the tendency of tumorigenesis hinder the therapeutic applications for iPS cells in treatment of human diseases. To this end, it remains largely unknown how the iPS process is subjected to regulation by upstream signaling pathway(s). Here, we report that Akt regulates the iPS process by modulating posttranslational modifications of these iPS factors in both direct and indirect manners. Specifically, Akt directly phosphorylates Oct4 to modulate the Oct4/Sox2 heterodimer formation. Furthermore, Akt either facilitates the p300‐mediated acetylation of Oct4, Sox2, and Klf4, or stabilizes Klf4 by inactivating GSK3, thus indirectly modulating stemness. As tumorigenesis shares possible common features and mechanisms with iPS, our study suggests that Akt inhibition might serve as a cancer therapeutic approach to target cancer stem cells.
Taking the Temperature of the Interiors of Magnetically Heated Nanoparticles

The temperature increase inside mesoporous silica nanoparticles induced by encapsulated smaller superparamagnetic nanocrystals in an oscillating magnetic field is measured using a crystalline optical nanothermometer. The detection mechanism is based on the temperature-dependent intensity ratio of two luminescence bands in the upconversion emission spectrum of NaYF4:Yb3+, Er3+. A facile stepwise phase transfer method is developed to construct a dual-core mesoporous silica nanoparticle that contains both a nanoheater and a nanothermometer in its interior. The magnetically induced heating inside the nanoparticles varies with different experimental conditions, including the magnetic field induction power, the exposure time to the magnetic field, and the magnetic nanocrystal size. The temperature increase of the immediate nanoenvironment around the magnetic nanocrystals is monitored continuously during the magnetic oscillating field exposure. The interior of the nanoparticles becomes much hotter than the macroscopic solution and cools to the temperature of the ambient fluid on a time scale of seconds after the magnetic field is turned off. This continuous absolute temperature detection method offers quantitative insight into the nanoenvironment around magnetic materials and opens a path for optimizing local temperature controls for physical and biomedical applications.
Perspectives on the Role of Fospropofol in the Monitored Anesthesia Care Setting

Monitored anesthesia care (MAC) is a safe, effective, and appropriate form of anesthesia for many minor surgical procedures. The proliferation of outpatient procedures has heightened interest in MAC sedation agents. Among the most commonly used MAC sedation agents today are benzodiazepines, including midazolam, and propofol. Recently approved in the United States is fospropofol, a prodrug of propofol which hydrolyzes in the body by alkaline phosphatase to liberate propofol. Propofol liberated from fospropofol has unique pharmacological properties, but recently retracted pharmacokinetic (PK) and pharmacodynamic (PD) evaluations make it difficult to formulate clear conclusions with respect to fospropofol's PK/PD properties. In safety and efficacy clinical studies, fospropofol demonstrated dose-dependent sedation with good rates of success at doses of 6.5 mg/kg along with good levels of patient and physician acceptance. Fospropofol has been associated with less pain at injection site than propofol. The most commonly reported side effects with fospropofol are paresthesia and pruritus. Fospropofol is a promising new sedation agent that appears to be well suited for MAC sedation, but further studies are needed to better understand its PK/PD properties as well its appropriate clinical role in outpatient procedures.
New Perspective for the Philosophy： Re-Construction ＆ Definition of the New Branches of Philosophy

In this article, author evaluated past/present perspectives about philosophy and branches of philosophy due to historical period, religious perspective, and due to their organized categories/branches or areas. Some types of interactions between some disciplines are given as an example. The purpose of this article is, to solve problems related with philosophy and past branches of philosophy, to define new philosophy perspective in the new system, to define new questions and questioning about philosophy or branches of philosophy, to define new or re-constructed branches of philosophy, to define the relations between the philosophy branches, to define good and/or correct structure of philosophy and branches of philosophy, to extend the definition/limits of philosophy, others. Author considered R-Synthesis as a method for the evaluation of the philosophy and related past branches of philosophy. This R-Synthesis includes general/specific perspective with eight categories, 21-dimensions, and twelve general subjects (with related scope and contents) for the past 12,000 years. It is a kind of synthesis of supernaturalism and naturalism, physics and metaphysics, others. In this article, author expressed 27 possible definitive/certain result cases of the new synthesis and defined the possible formation stages to express new theories, new disciplines, theory of interaction, theory of relation, hybrid theory, and others as constructional and/or complementary theories. These theories are considered for 21 major effective disciplines which are defined for a country and for the world. New philosophy perspective, branches of philosophy, and aims/purposes of R-Philosophy are defined to organize many inquiries about the name, number, and relation between special subject “X” and “philosophy of X” in some manner. This new perspective includes necessary and sufficient number of philosophy branches, and so it limits the number of “philosophy of X” in the philosophical system. New Era Philosophy is defined with its sub branches, its constructional philosophies, and with its 8D hybrid philosophy perspective. Ideal Philosophical System is defined with general/specific figure. Some of the new and/or re-constructed branches of philosophy explained with the new defined set of questions, new sub branches and constructional philosophies. Integration of the past/present branches of philosophy into the ideal philosophical system is explained generally. Philosophical interests of the some past philosophers and their relations with the ideal philosophical system expressed with table.
