Gravimetric and electrochemical studies of corrosion inhibition potential of acid and ethanol extract of siam weed on mild steel

The inhibition potency of acid and ethanol extract of siam weed was studied on the corrosion of mild steel in 1 M HCl using weight loss techniques, Tafel extrapolation, scanning electron microscopy and energy dispersive microscopy (SEM-EDS). The results from the weight loss revealed that the inhibition efficiency is dependent on the concentration of the extract and the temperature of the system. However, the ethanol extract has the highest inhibition efficiency of 83 %. The data obtained were found to be fitted into the adsorption models proposed by Langmuir and Freundlich. Morphological analysis indicates that the mild steel was well protected in the presence of the extracts. Tafel extrapolation shows that the extract acts as a mixed-type inhibitor.
Cultural Impact on e-Performance in Government Organizations in the United Arab Emirates

This paper examines the influence of cultural forces in accepting the implementation of technology systems that deal with assessment and evaluation of government employees to facilitate the transitional process from manual to e-performance assessment in governmental organizations in the United Arab Emirates. The research methodology followed is descriptive and semi-structured interviews with government employees and line managers involved in e- performance and assessment. This study finds that scholars have long argued that cultural characteristics influence behavior directly. This phenomenon, however, varies from one culture to the other depending on numerous factors that shape work ethics and norms in the workplace. This study suggests that the United Arab Emirates enjoys highly structured governmental organizations. This primarily results from the naturally inherited characteristics of being a high- context society.
Correlation of serum creatine phosphokinase and serum cholinesterase in organophosphate poisoning in children

Background: Organophosphate (OP) poisoning is one of the most common pesticide poisoning in India in adolescents because of its easy availability. Serum pseudocholinesterase levels are commonly used to assess the severity and to know the prognosis in OP compound poisoning. Serum creatine phosphokinase (CPK) levels is another lab parameter which gets deranged in OP poisoning and has been tried in adults to assess the severity and to know the prognosis. Authors objective was to study the correlation of serum pseudocholinesterase and serum CPK in organophosphate poisoning at admission and to compare outcome with serum CPK levels.Methods: All the children in the age group of 1 month to 18 yrs, who were admitted with the history of suspected OP compound poisoning were enrolled for the study. Estimation of cholinesterase and CPK levels were done at admission and after 1 week. Patients were categorised in to latent, mild, moderate and severe cases based on the S. Cholinesterase levels. These values were analysed to see the correlation.Results: Among 34 OP poisoning cases,13(38%) were males and 21(62%) were females. Mean age of study population was12.6+4.25 yrs. The median CPK values in latent, mild, moderate and severe cases were 121.5 IU/L,276.5 IU/L, 308IU/L and 467IU/L respectively (p=0.015). Spearman’s rho Correlation coefficient was -0.522 between S. Cholinesterase and S CPK at admission which was significant. The median serum CPK level after 1week in non survivors was 2498.0IU/L and in survivors was 201.0IU/L (p0.014). Conclusions: There was a strong negative relationship between serum cholinesterase and serum CPK at admission in OP poisoning. Follow up values at 1 week showed that significantly high serum CPK and low cholinesterase, which was also significant and was associated with mortality.
Exceptional Outcomes in L 2 Phonology : The Critical Factors of Learner Engagement and Self-Regulation

A number of studies attest to the late language learner’s ability to attain nativelike outcomes in morphology and syntax, with accent often the only linguistic hint of their non-native status. Nevertheless, some do end up sounding nativelike despite a late start. This article explores possible explanations for ’exceptional’ outcomes in L2 phonology, specifically, whether such learners’ abilities are due to innate talent, a metacognitive learning approach, a certain socialpsychological orientation, or specific kinds of experience. Various learners profiles are compared, an argument is made for learner engagement and self-regulation, and areas for future research are outlined.
CIRCULAR ECONOMY: NEW PARADIGM OR JUST RELABELLING? A QUANTITATIVE TEXT AND SOCIAL NETWORK ANALYSIS ON WIKIPEDIA WEBPAGES

Circular Economy has definitely gained a momentum among both, researchers and practitioners. The result is the production of multifarious knowledge, involving different disciplines such as economics, chemistry, design and Industrial Ecology. However, despite the steep growth of articles in Scopus, critics hold that blurriness in defining the Circular Economy is occurring and, due to its interdisciplinary but ambiguous nature, a systemic approach is required in order to set its boundaries. In this work, an innovative methodology is presented and discussed to identify which network of keywords exhaustively depicts the Circular Economy domain, in order to assess if the Circular Economy might be considered as a new paradigm or it represents a relabelling of already existent knowledge. The methodology consists in four steps: first, an initial seed list of keywords related to the Circular Economy is extracted from the Scopus database. Secondly, the network of the overall Wikipedia pages is discussed and, thirdly, two sub-networks, one representing the relevant fields and one the crucial technologies, are pointed out by classifying Wikipedia pages depending on the presence of a specific term in the first sentence. Finally, centrality indices are discussed and the most important clusters are highlighted, revealing the six main fields related to the Circular Economy: Sustainability, Material Flow Analysis, Waste Management, Water Management, Waste Electrical and Electronic Equipment (WEEE) and Bioeconomy.
Evidence from Detailed Petrographic Examinations of Casing Stones from the Great Pyramid of Khufu , a Natural Limestone from Tura , and a Man-made ( Geopolymeric ) Limestone

Contrary to the well-known hypothesis of construction of the Great Pyramids at Giza by carving and hoisting quarried limestone blocks, in 1974 a French research chemist, Joseph Davidovits, proposed a radically different hypothesis that the pyramid blocks are not quarried stone but cast-in-place “concrete” prepared with the soft, marly kaolinitic limestone of Giza that was readily disintegrated in water and mixed with locally available lime and natron. The lime-natron combination, according to Davidovits, dissociates the kaolinitic clay from the limestone and forms an alkali-aluminosilicate (zeolitic) “glue”, which he termed “geopolymer”. The “man-made” hypothesis was proposed as an alternative explanation to the apparent mysteries associated with the “carve-and-hoist” hypothesis in regard to the methods of construction and observations of some “unusual” minerals in pyramid samples that are rare in natural limestone. The purposes of the present study are to investigate: (a) evidence of microchemical signatures of the proposed lime-natron-clay-based geopolymeric chemistry in the binder phases of the pyramid samples; (b) textural, mineralogical, microstructural, and binder-microchemical comparisons among pyramid samples, natural limestone from Tura, and geopolymeric limestone; and (c) the reported “unusual” constituents in the pyramid samples, if any, and their possible sources. 1 The Great Pyramid of Giza was the world's tallest building from c. 2570 BC to c. 1300 AD (from http://en.wikipedia.org/wiki/Great_Pyramid_of_Giza, with permission).

Reluctant Regulators: Perspectives of Family Physicians on Monitoring Seniors' Driving

The authors examined perceptions of family physicians regarding their role of monitoring seniors' driving. Three focus groups were held with family physicians that had 25% or more seniors in their practice. Physicians were asked about their role in regulating driving, their understanding of self-regulation, and risk factors requiring attention. Data were analyzed using an inductive analysis approach. Three themes emerged describing physicians' perspectives: reluctant regulators; making the role more manageable; and “grey” areas. Physicians are unhappy in their role and have many ideas for improving the system. Until they feel more comfortable, physicians will not be able to assume a proactive role, helping seniors to drive safely, longer.
Supercooled Drizzle Development in Response to Semi-Coherent
Vertical Velocity Fluctuations Within an Orographic Layer Cloud

Abstract. Observations of super-cooled liquid water are nearly ubiquitous within wintertime, orographic layer clouds over the intermountain west; however, observations of regions containing super-cooled drizzle drops (SCDDs) are much rarer and the factors controlling SCDD development and location less well understood. As part of the Seeded and Natural Orographic Wintertime clouds – the Idaho Experiment (SNOWIE) goal of improving understanding of natural cloud structure, this study examines the role of fine-scale (sub-kilometer) vertical velocity fluctuations on the microphysical evolution and location of SCDDs within the observed mixed-phase, wintertime orographic clouds from one research flight of SNOWIE. This flight saw SCDDs develop in an elevated, postfrontal layer cloud with cold cloud tops (T
Vivaldi : A Decentralized Network Coordinate System

In this paper, the authors propose a decentralized coordinate calculation and assignment algorithm, Vivaldi, along with a hybrid coordinate system combining Euclidean coordinates and directionless height element. The purpose of the algorithm is to accurately predict the round-trip times (RTT) between any two hosts directly from their coordinates without incurring too much overhead to contact each other first. Evaluation of the Vivaldi algorithm, conducted using a packet-level network simulation with both real world RTT data and synthetic data sets, shows that Vivaldi is accurate, robust against high error nodes, and rapidly responsive to network changes. By comparing the performances of Vivaldi under several possible coordinate spaces, the authors demonstrate that a two dimensional Euclidean model with height element can capture the Internet’s underlying structure and predict the RTT very well.
Addressing California ’ s Housing Shortage : Lessons from Massachusetts Chapter 40 B

California, particularly in its coastal cities, is facing a housing affordability crisis. Median rents across the state have increased 24 percent since 2000, while at the same time median renter household incomes have declined 7 percent. While multiple factors contribute to these rising rents, it is clear that supply matters, and there is an urgent need to expand supply in equitable and environmentally sustainable ways. Over the past three decades, California has added only about half the number of units it needs to keep housing costs in line with the rest of the United States. Between 1980 and 2010, the number of housing units in the typical U.S. metro grew by 54 percent, compared with 32 percent for California’s coastal metros. Production of units affordable to lowand moderateincome households has been even more dismal, with most cities across the state failing to meet their Regional Housing Needs Allocation (RHNA) targets. For example, in the Bay Area, cities permitted less than 30 percent of their very low, low, and moderate-income housing

Duplication of the Ace . 1 Locus in Culexpipiens Mosquitoes from the Caribbean

In Culex pipiens mosquitoes, A ChE1 encoded by the locus Ace. 1 is the target of organophosphorus and carbamate insecticides. In several resistant strains homozygous for Ace.1 aR, insensitive ACHE1 is exclusively found. An unusual situation occurs in two Caribbean resistant strains where each mosquito, at each generation, displays a mixture of sensitive and insensitive AChE1. These mosquitoes are not heterozygotes, Ace.1Rs, as preimaginal mortalities cannot account for the lethality of both homozygous classes. This situation is best explained by the existence of two Ace.1 loci, coding, respectively, a sensitive and an insensitive ACHE1. Thus, we suggest that in the Caribbean a duplication of the Ace.1 locus occurred before the appearance of insecticide resistance at one of the two copies.

Clustering Tweets to Discover Trending Topics about دبي (Dubai)

Nowadays, a lot of people targeting social networks to learn what are the trending topics and the news alongside the huge flow of texts posted daily in social networks. One of these social networks is Twitter a microblogging hub and rich environment of data. Scanning tweets online is a hard task and searching effortlessly to find intended topic from huge amount of data is also time consuming. This paper is intended to propose a solution of collecting Twitter of the corpus يبد (Dubai) by using Zapier website and storing them in Google sheet. Then, creating a word vector to the tweets by using TF-IDF methodology. After this, log results into kmean clustering algorithm with cosine similarity to measure similarity between objects of each cluster. The results demonstrate that internal evaluation techniques failed to evaluate quality of the cluster. In addition to that, interesting topics was found about يبد (Dubai). Moreover, better results achieved by using Filter Tokens (by Region) than without using it. The data were collected for the experiment at several periods to ensure getting the most trending topics about يبد (Dubai). All of the results found in this paper tested with real tweets.
Degree of Conversion and Polymerization Shrinkage of Low Shrinkage Bulk-Fill Resin Composites

Background: The effectiveness of each resin composite material composition in enabling homogeneous monomer conversion and reducing polymerization shrinkage (PS) is an important issue. Thus, this study aimed to evaluate the degree of conversion (DC) and PS of low-shrinkage bulk-fill composites (BFCs) in 4-mm thickness. Materials and Methods: Four bulk fill (Tetric EvoCeram Bulk Fill, Sonic Fill, XTra Fill, and Venus Bulk Fill) and one conventional (Filtek Z350 XT) resin composites were tested in this study. Teflon molds of 4-mm depth were used to prepare resin composite specimens. All tested resin composites were packed in bulk then light cured for the recommended time by their manufacturers. DC% was determined by Fourier transform infrared spectroscopy; PS was determined using the strain gauge method. Data were subjected to one-way ANOVA/Tukey's test (α = 0.05). Results: DC% results were as follows: Venus Bulk Fill > XTra Fill > Sonic Fill > Tetric EvoCeram Bulk Fill > Filtek Z350 XT with a significant difference between each others at P ≤ 0.001. For PS %, significant difference resulted between tested groups at P ≤ 0.001. Where Venus Bulk Fill < XTra Fill = Sonic Fill < Tetric EvoCeram Bulk Fill < Filtek Z350 XT. Conclusions: Low-shrinkage resin monomers seem to be beneficial for reducing PS with enhancement in the DC. Increased filler loading in BFCs had a positive effect on reducing PS, while its effect on the DC was material dependent.
Deep Learning for Computer Vision IMVIP 2019 : Irish Machine Vision and ImageProcessing 2019 Comparing Data Augmentation Strategies for Deep Image Classification

Currently deep learning requires large volumes of training data to fit accurate models. In practice, however, there is often insufficient training data available and augmentation is used to expand the dataset. Historically, only simple forms of augmentation, such as cropping and horizontal flips, were used. More complex augmentation methods have recently been developed, but it is still unclear which techniques are most effective, and at what stage of the learning process they should be introduced. This paper investigates data augmentation strategies for image classification, including the effectiveness of different forms of augmentation, dependency on the number of training examples, and when augmentation should be introduced during training. The most accurate results in all experiments are achieved using random erasing due to its ability to simulate occlusion. As expected, reducing the number of training examples significantly increases the importance of augmentation, but surprisingly the improvements in generalization from augmentation do not appear to be only as a result of augmentation preventing overfitting. Results also indicate a learning curriculum that injects augmentation after the initial learning phase has passed is more effective than the standard practice of using augmentation throughout, and that injection too late also reduces accuracy. We find that careful augmentation can improve accuracy by +2.83% to 95.85% using a ResNet model on CIFAR-10 with more dramatic improvements seen when there are fewer training examples.

Research Evaluation of an Australian Peer Outdoor Support Therapy Program for Contemporary Veterans’ Wellbeing

Abstract Longitudinal quantitative and qualitative analyses were conducted for male contemporary returned post-deployed (CRPD) veteran participants of an Australian 6-day structured peer outdoor support therapy (POST) program. Results demonstrated significant reductions in depression, anxiety and stress by day 6 compared to baseline, which was maintained at 2 months follow-up. Self-efficacy, overall life satisfaction and satisfaction with mental health also improved significantly. Qualitative analysis identified several key factors experienced: a sense of shared identity, involvement, and belonging with others, and increased self-determination and personal competence. Such programs may be an important adjunct or precursor to other forms of veteran therapeutic support.
A Study of Post Obturation Pain Following Single Visit Root Canal Treatment

Introduction: Root canal treatment (RCT) is a common procedure in dentistry. In recent year, single visit RCT has gained increased acceptance as a treatment procedure of RCT. One of the problem of RCT is post obturation pain. Objectives: This study was conducted to determine the incidence of post obturation pain related to single visit RCT in asymptomatic non-vital single rooted teeth. Methods: A total 60 cases of endodontically involved asymptomatic non-vital single rooted teeth without any evidence of periapical radiolucency in radiograph, were selected for this study. The canals of all teeth were prepared and filled using the standarized preparation and lateral condensation filling technique. The frequency of post obturation pain was recorded as no pain, slight, moderate and severe pain and evaluated at the day l and at the day 7 after obturation. Result: Out of the 60 patients involved in the study, 37 patients had no pain, 12 patients had slight pain and 11 patients had moderate pain at the day 1 after post obturation. At the day 7 after post obturation, 50 patients had no pain, 8 patients had slight pain and 2 patients had moderate pain. No one showed severe pain in both follow up days. Conclusion: Statistically significant differences were found in the incidence and degree of pain between two follow up days. Incidence of pain was more in 1st post obturation day and decreased thereafter. Chattagram Maa-O-Shishu Hospital Medical College Journal Volume 12, Issue 3, September 2013: 16-19
Cross-contamination of rapeseed seeds by postharvest insecticide residues during seed storage

A two-year investigation in grain storage companies allowed us to follow the course of rapeseed batches from reception at the storage facility to outloading. Each of these batches was sampled outloading, and was analysed for insecticide residues content. Traceability of oilseeds established by grain-store managers allowed us to identify cross-contamination sources. Substances discovered were mostly pyrimiphos-methyl, malathion, plus chlorpyriphos-methyl and deltamethrin. Pyrimiphosmethyl was the most commonly detected active substance, and caused most cases of nonaccordance with regulatory levels in rapeseed. Main cross-contamination hazard resulted from treatment of cereals at their receipt during the same period of rapeseed delivery at the grain store, especially when these cereal treatments were systematically achieved or frequent at that elevator. Another situation led to cross-contamination, but generally at a lower extent: rapeseed stored in bin that contained previously treated cereals, or loaded in empty bins with handling equipment treated before the receipt of rapeseed.
