Provenance of the Newfoundland Appalachian foreland basins

The tectonic history of the Appalachian orogen is recorded in the adjacent foreland. Offshore seismic data suggest that an initial, Middle Ordovician foreland basin was filled by sources in Newfoundland, whereas the Late Ordovician foreland basin was loaded and filled by sources to the SW, in the Québec segment of the orogen, where NW-vergent Taconian arc-continent collision may have continued later than in Newfoundland. We test this hypothesis using U/Pb ages of detrital zircon within foreland basin successions in western Newfoundland. Previously published results from the oldest foreland succession, the Middle Ordovician Goose Tickle Group, demonstrate ages similar to units preserved with the Humber Arm Allochthon, emplaced during Middle Ordovician Taconic orogenesis, including a predominant Paleoproterozoic peak at 1.85 Ga. In this study we investigated U/Pb geochronology of detrital zircon from younger foreland successions from Upper Ordovician to Devonian. The largest proportion of analyses within all foreland successions fall between 0.95 and 1.3 Ga, with largest peaks occurring between 1.0 and 1.1 Ga, typical of zircon derived from the Grenville Orogen. Earlier Mesoproterozoic and Paleoproterozoic ages range from 1.3 to 2.0. The abundance of Mesoproterozoic grains and conspicuous lack of 1.85 Ga Paleoproterozoic zircon in the overlying Upper Ordovician Long Point Group and latest Silurian to Early Devonian Clam Bank Formation indicates that these sediments were not derived from units within the Humber Arm Allochthon. Probability density plots of continental margin units in the Québec/New England segment of the orogen demonstrate a similar strong Mesoproterozoic and weak Paleoproterozoic signature, suggesting derivation of the Long Point Group from the Québec segment of the orogen. Within the mid-Paleozoic Clam Bank - Red Island Road succession, typical Gondwanan ages are absent and 1.0 Ga grains derived from the Grenville Orogen are abundant. This is consistent with underthrusting of the Gondwanan microcontinents Ganderia and Avalonia during Salinic and Acadian orogenesis. Only Mesoproterozoic zircon grains were found in the Early Devonian Red Island Road Formation, consistent with derivation from Mesoproterozoic Grenville massifs in western Newfoundland or Cape Breton Island which were exhumed during Devonian Acadian inversion.
Investigation of mechanical properties of nanocellulose reinforced synthetic polymer composite

In Sri Lanka, a considerable percentage of agricultural waste such as rice straw and sugarcane bagasse is discharged to the environment without a commercial use and forms a huge organic environmental pollution. Therefore, the agricultural wastes can be used to extract cellulose and indirectly apply an additional value to the abundant priceless wastes. Nanocellulose is a cellulosic material which has at least one dimension in the nanometre range and has a potential for polymer reinforcement. Based on their structure nanocellulose extracted from plant species are categorised into two; nanofibrillated cellulose (NFC) and nanocrystalline cellulose (NCC). The present paper discussed the surface modification of NFC using Silane coupling agent (Si-69) and fabrication of silylated NFC reinforced polypropylene (PP) composites with different loadings of NFC from 0-5 wt. % by adding 0.5 wt. % per sample. The mechanical properties of the composite samples were compared with respect to neat PP and Scanning electron microscope (SEM), Fourier-transform infrared spectroscopy, X-ray diffraction, mechanical tests (tensile strength, percentage elongation at break, impact strength and hardness), percentage water absorption and melt flow index (MFI) were used to characterize the developed composites. The experimental results emphasize the wide improvement of mechanical properties with extremely narrow reduction of water absorption and processability of silylated NFC based PP than pure PP. The 3.5% silylated NFC reinforced PP composite indicated the highest improvement in mechanical properties such as hardness, tensile and impact strength, a 7.4%, 12.6%, and 86.1% higher than the neat PP, respectively.
Effect of Dehydration on Dielectric Measurements of Biological Tissue as Function of Time

The lack of a standardized operating protocol for dielectric measurements of biological tissues makes it difficult to objectively compare reported dielectric properties since these properties are affected by multiple environmental confounders. This work investigates the effect of dehydration on dielectric properties as a function of time at different temperatures. Additionally, it proposes a dehydration mitigating technique. The dielectric properties of porcine liver samples were measured during a 35 minute measurement interval at different temperatures. A first set of six experiments was conducted in standard laboratory conditions. A second set of two experiments was conducted with a modified measurement setup with reduced air flow. Under standard conditions, relative changes in the dielectric properties up to 9% were observed. With the modified setup, the relative change was halved compared to standard conditions. This reduction indicates that the environmental conditions have a considerable influence and that modifying these conditions extends the stability of the dielectric properties over time. For several applications relying on the difference in dielectric properties between healthy and malignant tissue, an error of 9% in measured data is on the same order as the effects of interest. The expected difference in dielectric contrast could be obscured due to dehydration.
Frequency of Rotavirus in Children with Acute Gastroenteritis

It is important to follow up the epidemiologic and clinical characteristics of the viral especially rotavirus gastroenteritis to develop strategies for prevention and treatment. Therefore we investigated the rotavirus gastroenteritis in acute diarrhea patinets in our clinic. Stool samples of 263 patients admitted to outpatient clinic or emergency room of COMU Faculty of Medicine Hospital with the symptom of acute diarrhea were screened retrospectively from medical records. Stool samples had been studied with the monoclonal antibody based chromatographic immunoassay (Rota-Adeno Virus Combo Test Device, Ecotest, China). 263 medical records were screened. Rotavirus antigen was positive in 62 cases (23.6%). It was 34.5% in children under 2 years. Rota positivity according to the seasons was as follows: 27.8% in spring, 14.6% in summer, 26.3% in autumn and 21.4% in winter. As a result, acute diarrhea case management should be done for age and seasonal distribution. In these cases unnecessary antibiotic usage should be avoided by rapid diagnostic test when required.
Achieving thermally conductive low loss PVDF-based dielectric composites via surface functionalization and orientation of SiC nanowires

Semi-conductive silicon carbide (SiC) nanowires were amino-functionalized to achieve better dispersion in poly(vinylidene fluoride) (PVDF) matrix. It was found that PVDF based composites with amino-functionalized SiC (f-SiC) nanowires exhibited lower loss tangent than their counterparts with bare SiC nanowires, especially at a filler loading of 13.8 vol%. The loss tangent at 1 kHz of PVDF/f-SiC nanowires (86.2/13.8, v/v) composite is only 0.048, which is nearly one quarter of that of its counterpart with bare SiC nanowires. The nearly one order of magnitude lower AC conductivity at 1 kHz is responsible for the remarkable decrease of the loss tangent, since the interlacing of f-SiC nanowires was avoided via their parallel orientation, facilitated by the enhanced interfacial interaction. In addition to the low loss, the PVDF/f-SiC nanowires (86.2/13.8, v/v) composite exhibited about twofold increase of the dielectric permittivity at 1 kHz, compared to neat PVDF. Moreover, the thermal conductivity of PVDF/f-SiC nanowires (86.2/13.8, v/v) composite was increased to twice that of neat PVDF. The thermally conductive, high dielectric permittivity, and low loss PVDF/f-SiC nanowires composites may find potential applications in capacitors for microelectronics.
Mejora de las propiedades termomecánicas de grafito isótropo, elaborado a partir de mesofase carbonosa, mediante la adición de carburos

This work demonstrates the possibilities for optimization of doped fine grain graphites with high thermal conductivity and high thermal shock resistance for application as plasma-facing materials at those areas of the vessel wall in fusion devices receiving the highest particle and power loads. A mixture of carbonaceous mesophase powder and different fine grain carbides (B 4 C, TiC, VC, ZrC and WC) was used as starting material. These carbides act as catalysts, decreasing the graphitization temperature. VC acts as catalyst of the graphitization at the lowest temperature, and ZrC is the most effective catalyst of all investigated carbides. With increasing graphitization temperature, the open porosity of all doped materials becomes closed, suggesting the existence of a diffusion mechanism responsible for both the catalytic effect and the closing of the open porosity. Carbides addition does not strongly influence the mechanical properties of pure graphite.
Altmetrics

According to information scientists, information is modified into knowledge by adding experience. Researchers need powerful and successful filters to help them stay abreast of literature in their field, as well as methods to track the impact of their own research in often very specialized areas of interest. Traditional mechanisms such as peer review and citation searching using bibliometrics are no longer sufficient tools to aid researchers. How can librarians become leaders and powerful allies in this new landscape? Enter the world of Altmetrics. Altmetrics, or alternative citation metrics, provides researchers and scholars with new ways to track influence across a wide range of media and platforms. Altmetrics are metrics and qualitative data that are complementary to traditional, citation-based metrics. Altmetrics is a field of web-based metrics that accounts for total author influence which also looks beyond journal and monographic citation counts to the social web. The aim of this chapter is to explain the concept of library and librarian involvement with altmetrics.
Chemical Characterization and Tribological Behavior of Kitchen Chimney Dump Lard (KCDL) as a Bio-lubricant

Received: 2 March 2019 Accepted: 28 May 2019 Immense study of environment friendly and renewable lubricant is now a day’s major field of research for the overall sustainable development. Most of the challenges are taken towards recyclable waste to product. The Present work investigates the characterization and frictionwear behavior of Inconel 800 against 100Cr Steel applying Kitchen Chimney Dump Lard (KCDL) as a bio-lubricant. The characterization study by FTIR (Fourier Transform Infrared Spectroscopy) has shown the presence of fatty acid ester in KCDL. Tribological tests have been performed on Inconel 800 at different load and speed in a lubricated condition. From the experiment, it has been investigated that there is no such change in specific wear rate due to better lubricity property and the presence of strong bonded beneficial tribofilm on KCDL. The coefficient of friction (COF) increases with the increase in speed and load but it is less compared to waste cooking oil, and Castrol GTX 20W-50.
Hepatitis B Vaccine Coverage Rate and Influential Factors among Children in Hubei Province

Objective To evaluate hepatitis B(HB) vaccine coverage rate and its influential factors.Methods 843 children born in 2001 were investigated by stratified multistage random cluster sampling. Resuts The HB immunization coverage rate of 3 doses, eligible vaccination and timely vaccination rate of the first dose were 83.27%, 75.68%, 49.23% respectively. The HB immunization coverage rate of 3 doses in urban and rural areas of higher, medium and lower economic levels were 96.19%, 88.15%,80.09%, 68.72% respectively. The main reason for missing immunization were: HB vaccine not provided at the local immunization site,parents not knowing HB was recommended,and the vaccine charge was too expensive.This paper analyzed the factors affecting HB vaccination rate,and made suggestions to promote HB vaccination rate.
Porosity Formation Mechanism and Reduction Method in CO2 Laser Welding of Stainless Steel.

A large amount of porosity is liable to be formed in high power CO2 laser welds of stainless steels. The formation mechanisms of porosity have not been satisfactorily understood up to the present. In this study, therefore, microfocused X-ray transmission in-situ observation system was utilized to observe the behavior of a keyhole and the formation situations of bubbles and pores during high power CO2 laser welding. It was observed that a keyhole fluctuated in geometry unstably and vibrated up and down dynamically, and accordingly many bubbles were frequently generated in the bottom part of a molten pool from the tip of the deep keyhole. Almost all bubbles were captured into spherical pores by solidifying solid-liquid interface during floating up near the bottom part of the weld pool. Moreover, it was revealed that partial penetration welding with a forward inclination of a laser beam or in N2 shielding gas, and full penetration welding in any shielding gas were beneficial to the reduction and prevention of porosity because the formation of bubbles was suppressed or prevented.
Efeito de um modelo de intervenção psicodinâmica ultrabreve para mulheres com transtorno de estresse agudo e transtorno de estresse pós-traumático : estudo naturalístico

The aim of this study was to evaluate the effect of an ultra-brief psychodynamic intervention (UBPI) for women with post-traumatic stress disorder (PTSD) and acute stress disorder (ASD). Methods: 27 women who completed 4-6 treatment sessions were assessed before and after the intervention by means of a standard protocol, Davidson Trauma Scale (DTS), Beck Depression Inventory (BECK), Defense Style Questionnaire (DSQ40), Clinical Global Impression (CGI) and the Global Assessment of Functioning (GAF). Results: After treatment, there was a reduction in symptoms according to DTS, BECK, CGI and GAF scales, even controlling for the use of psychotropic drugs. The Cohen’s effect size was large CGI d =1,18, GAF d = 1,03, DTS d =0,95 e BDI d =0,9. There was a reduction in the use of projection and an increase in the humour defense, after treatment. The reduction in PTSD symptoms was correlated with immature factor score decreasing. Conclusions: Although, controlled studies are required to confirm these findings, this study suggest that an ultra-brief psychotherapy intervention could be an interesting treatment alternative for PTSD and ASD patients especially in public health settings.
A parametric study of stress concentration issues in unidirectional laminates

Abstract This paper carries out a parametric analysis to evaluate the effect of circular holes on the strength of unidirectional laminae. Stroh Formalism is used to describe the elastic stresses around the border of circular holes in large plates subjected to in-plane loads and Puck failure criterion is applied to estimate the critical load. Finite plates are investigated using the Finite Element software ANSYS. Matrix failure is observed for most cases and the applied load on the damage onset is smaller than 10% of the unnotched strength and finite plate effect induces changes on the failure mechanism during damage propagation.
Assessing socioeconomic status of Twitter users: A survey

Every day, the emotion and opinion of different people across the world are reflected in the form of short messages using microblogging platforms. Despite the existence of enormous potential introduced by this data source, the Twitter community is still ambiguous and is not fully explored yet. While there are a huge number of studies examining the possibilities of inferring gender and age, there exist hardly researches on socioeconomic status (SES) inference of Twitter users. As socioeconomic status is essential to treating diverse questions linked to human behavior in several fields (sociology, demography, public health, etc.), we conducted a comprehensive literature review of SES studies, inference methods, and metrics. With reference to the research on literature’s results, we came to outline the most critical challenges for researchers. To the best of our knowledge, this paper is the first review that introduces the different aspects of SES inference. Indeed, this article provides the benefits for practitioners who aim to process and explore Twitter SES inference.
Commute mode share and access to jobs across US metropolitan areas

How much of the variation in transit mode share is attributable to accessibility is not well understood, despite its significant policy implications. It is hypothesized that better transit accessibility leads to higher transit mode share. This paper explains block group level transit mode share using transit accessibility in a logistic model for 48 major US metropolitan areas. Transit accessibility alone explains much of the variation in transit mode share for all 48 regions despite their geographical differences (adjusted R2 0.61, potential accessibility); models for individual cities have stable and interpretable parameters for transit accessibility. The models better explain mode share in cities with higher person weighted transit accessibility and larger populations; an adjusted R2 of 0.76 is achieved for New York City with transit accessibility as the only explanatory variable. Additional automobile accessibility and income variables modestly improve model fit. Time–decay functions fitted to accessibility measures better explain mode choice than the isochrone accessibility, and suggest the catchment area affecting transit mode choice to be within 35 minutes. This work contributes to the understanding of transit mode share by solidifying its link with accessibility, which is determined by the structure of the transport network and land development.
Relapse rate of severe generalized psoriasis after treatment with acitretin or etretinate. Results of the first randomized double-blind multicenter half-year follow-up study

Acitretin (A) was compared to etretinate (E) in severe generalized psoriasis of plaque-like type in a randomized double-blind multicentric study over twelve weeks. The results showed that after 50 mg/d monotherapy both groups had a 60.4% and 60.0% improvement, respectively. PSI-score (x) decreased from 30.0 (A) and 28.5 (E) at baseline to 9 and 11.5 points, respectively. The clinical efficacy was comparable at all time points and at the end of the drug treatment phase. Thirty-two patients after A and 30 after E terminated the drug phase of the study with very good to excellent results and gave their consent to enter the double-blind randomized follow-up part of the study
The efficacy of MSM (methylsulfonylmethane) incorporated into ultrasound gel using phonophoresis in the treatment of an acute facet syndrome in the cervical spine

Health professionals, while differentiated in their philosophies and choice of practice, still endeavour to expand the choice of effective and trustworthy techniques that can be applied to the individual needs of a patient. Therapeutic ultrasound is one such treatment that is used by many health practitioners. Ultrasound is one of the complementary treatments used to treat an acute cervical facet syndrome. Thermal ultrasound has the ability to decrease pain, stiffness, muscle spasm and inflammation of the tissue surrounding an acute cervical facet (Wyatt, 2004 and Reid, 1992). The current ultrasound treatment regimens for acute cervical facet syndromes are time consuming, in that they require a series of ultrasound treatments (Wyatt, 2004). Methods that could improve ultrasound treatment regimens in the treatment of acute cervical facets, by decreasing the amount of ultrasound treatments required and by increasing the effectiveness of the treatment would be beneficial. This research aims to test, in a clinical environment, the efficacy of MSM (methylsulfonylmethane) incorporated into ultrasound gel used with ultrasound in the treatment of an acute cervical facet syndrome. Participants were recruited from the University of Johannesburg Chiropractic Day Clinic. They were eligible to participate in the study once they met the inclusion and exclusion criteria. Participants were recruited by means of word of mouth as well as with the use of advertisements that were placed around the respective campuses of the University of Johannesburg. Thirty participants who presented with an acute cervical facet syndrome, volunteered for this comparative study. The study was double blinded, in which neither the researcher nor the participants knew which bottle contained the MSM incorporated into ultrasound gel or the standard ultrasound gel. It was only after the trials were completed that it was made know that group A received the MSM incorporated into ultrasound and group B the standard ultrasound. Group A received ultrasound treatment utilising MSM incorporated into ultrasound gel causing phonophoresis of the product’s ions, over the acute facets in the cervical spine. Group B received ultrasound treatment, using regular ultrasound gel, over the acute facets in the cervical spine.
Effects of yarn type, process history, softener type and concentration on wicking and drying properties of cotton plain knitted fabrics

Abstract Wicking and drying performances of knitted cotton fabrics made from siro, ring and open-end yarns were investigated before and after bleaching and dyeing procedures. Moreover, the samples were treated with cationic, non-ionic and silicone softeners at various concentrations. The data obtained were evaluated using one-way analysis of variance (ANOVA) as well as independent t-tests, and the results were discussed comparatively. The results showed that the selected parameters were highly effective on the wicking and drying behaviors of cotton plain knitted fabrics. Fabrics made from siro yarns tended to perform better. Dyeing process caused improvement of fabric wicking and drying behaviors. Also, application of silicone, especially at higher concentrations, was shown to negatively affect the discussed comfort properties, probably due to silicone double-layer formation with polar outside.
Integrated High- ( ) MIM Capacitor With Cu/Low- Interconnects for RF Application

We demonstrate a high-performance metal-high κ insulator-metal (MIM) capacitor integrated with a Cu/low-κ backend interconnection. The high-κ used was laminated HfO 2 -Al2O 3 with effective κ ∼ 19 and the low-κ dielectric used was Black Diamond with κ ∼ 2.9. The MIM capacitor (∼ 13.4 fF/μm 2 ) achieved a Q-factor ∼ 53 at 2.5 GHz and 11.7 pF. The resonant frequency f T was 21% higher in comparison to an equivalently integrated Si 3 N 4 -MIM capacitor (∼ 0.93 fF//μm 2 ) having similar capacitance 11.2 pF. The impacts of high-κ insulator and low-κ interconnect dielectric on the mechanism for resonant frequency improvement are distinguished using equivalent circuit analysis. This letter suggests that integrated high-κ MIM could be a promising alternative capacitor structure for future high-performance RF applications.
