Study on the fluidity of poly-acrylic CWS additives on three coal samples

In the experiment,four kinds of poly-acrylic additives were used to make coal water slurries(CWS)of three kinds of coal(Changcun coal,Changcun coal slime,Bazhou raw coal),meanwhile comparing with the results of naphthalene additives.From the experiments,to Changcun coal and Changcun coal slime,comparing with the naphthalene,the dosage of poly-acrylic acid additives is lower 0.20%~0.45% and the coal concentration of CWS adding poly-acrylic additives is higher 2%~5%;to Bazhou raw coal,the highest coal concentration of CWS adding poly-acrylic acid additives is 72%~73% and the dosage of additives is 0.6% while the naphthalene cannot be used to make coal water slurry.
Revisiting Truth or Triviality

Anderson, Lindsay, and Bushman (1999) compared effect sizes from laboratory and field studies of 38 research topics compiled in 21 meta-analyses and concluded that psychological laboratories produced externally valid results. A replication and extension of Anderson et al. (1999) using 217 lab-field comparisons from 82 meta-analyses found that the external validity of laboratory research differed considerably by psychological subfield, research topic, and effect size. Laboratory results from industrial–organizational psychology most reliably predicted field results, effects found in social psychology laboratories most frequently changed signs in the field (from positive to negative or vice versa), and large laboratory effects were more reliably replicated in the field than medium and small laboratory effects.
Can athletes’ reports of self-regulated learning distinguish deliberate practice from physical preparation activity?

ABSTRACT Sustained persistence in deliberate practice (DP) could be aided by engagement in adaptive motivational and metacognitive types of self-regulated learning (SRL) processes. We examined relationships between SRL and each of DP and physical preparation (PP; e.g., cross-training) in supervised, unsupervised, social and non-social practice contexts. 272 individual-sport athletes (from city to international level; M sport activity = 13.54 hrs/wk; 200 males, ages 18–35) completed the Self-Regulation of Learning Self-Report Scale and reported weekly DP and PP amounts. We found contrasting results depending on specific SRL processes. Self-monitoring was related to DP (total, supervised, social conditions) but inversely related to PP. Effort was inversely related to supervised DP but positively associated with PP. Planning was associated with DP, and reflection and self-efficacy related to PP. We discuss the contrast between DP and PP, highlighting differences in the nature of these practice activities, and self-monitoring as a key SRL process for DP.
THE TEMPORAL COURSE OF SELF – FORGIVENESS JULIE

This study examined the temporal course of self–forgiveness using 8 waves of data collected from 148 participants. Self–forgiveness increased linearly over time, and fluctuations in 6 time–varying covariates were related to changes in self–forgiveness beyond those accounted for by the self–forgiveness trajectory. Decreases in guilt, perceived transgression severity, and conciliatory behavior toward a higher power were associated with increases in self–forgiveness. Increases in perceived forgiveness from the victim and a higher power and conciliatory behavior toward the victim were also related to increases in self–forgiveness. These findings suggest that self–forgiveness is a dynamic process associated with multiple factors and lend preliminary support to J.H. Hall and F.D. Fincham’s (2005) theoretical model of self–forgiveness.
Investigations on Drilling of Bidirectional Cotton Polyester Composite

Cotton fiber composites are currently used in the interior parts of automobiles, insulation boards, fiber boards, and various parts of high-friction mechanical assemblies. These composites are subjected to machining operations. Drilling is an indispensable machining operation for assembly of different parts. The present work aimed to carry out experimental and analytical investigations on drilling of bidirectional cotton polyester composite. Influence of feed, spindle speed, and drill point angle on machining characteristics like thrust force, torque, and delamination factor was studied by conducting experiments derived from Taguchi's L27 orthogonal array. To determine the significance of each drilling process parameters and their interactions, analysis of variance (ANOVA) test was conducted. Modeling of drilling parameters was carried out through multiple regression analysis and their optimization for minimizing cutting forces and machining induced damage was carried out using signal to noise ratio analysis.

However, LSPR with narrowbandwidth(BW)isobservedonlyinaselectfewnoblemetals,andferromagnetsarenotamongthem. Here, we report the discovery of LSPR in ferromagnetic Co and CoFe alloy (8% Fe) in contact with Ag in the form ofbimetallic nanoparticles prepared bypulsed laser dewetting.

The appearance of theFPislikelyduetoplasmonicinteractionbetweenthecontactingAgandConanoparticles.Sincethereisno previous evidence for materials that simultaneously show ferromagnetism and such intense LSPRs, this discovery may lead to the design of improved plasmonic materials and applications. It also demonstrates that materials with interesting plasmonic properties can be synthesized using bimetallic nanostructures in contact with each other.
Quantitative visualization of asymmetric gas flow in constricted microchannels by using pressure-sensitive paint

Asymmetric flow in constricted microchannel devices was quantitatively investigated using a pressure-sensitive paint (PSP) technique. For microchannel devices with constriction ratios of 2 : 1 and 5 : 1, detailed pressure maps for the region around the constriction structure were obtained and enabled visualization of the flow field. Symmetric flow was observed in the microchannel device with a constriction ratio of 2 : 1 at the Reynolds number range 2–165. In the microchannel with a constriction ratio of 5 : 1, a deflected flow pattern was clearly identified from PSP measurements at Reynolds numbers exceeding 107. Furthermore, PSP measurements showed a pressure difference of up to 2.5 kPa between the two lateral locations corresponding to y = ±0.15 W (W is the microchannel width) downstream of the constriction at a Reynolds number of 279. The pressure difference resulted from asymmetric bifurcation of the flow.
Diel and tidal rhythms in diving behaviour of pelagic sharks identified by signal processing of archival tagging data

Patterns of vertical movement in pelagic predators can be highly complex, reflecting behaviours such as foraging, thermoregulatory excursions and spawning. Here we used fast Fourier analysis to identify periodicity in the vertical movements of 6 basking sharks Cetorhinus maximus from archival tagging data that totalled 595 d. We analysed quantitatively fine-scale vertical movements of basking sharks over seasonal scales (May to February) and detected predominant periodicities related to the vertical movements of the sharks' zooplankton prey. Normal and reverse diel vertical migration (DVM) represented the main periodic dive behaviour, occurring for 11 to 72% of individual track times. A tidal pattern of vertical movement, previously unreported for sharks, was also identified. A possible mechanism for this behaviour appears related to the shark exploiting tidally-induced aggregations of zooplankton prey at depth. The youngest shark tagged showed a markedly different pattern of vertical behaviour. Long-term data sets of swimming depth are becom- ing increasingly available for pelagic predators from pressure-sensitive data loggers. This study demonstrates the utility of signal processing techniques in objectively identifying both expected and unexpected periodicity in these continuous, high-resolution tracks.
Pompe disease: An Indian series diagnosed on muscle biopsy by ultrastructural characterization

ABSTRACT Pompe disease (PD) is a lysosomal storage disorder characterized by glycogen accumulation in muscle, with infantile-onset (IOPD) and late-onset (LOPD) types. Nineteen cases of PD were diagnosed over a 14-year period on muscle biopsy by ultrastructural examination. Pools of glycogen (intralysosomal and cytoplasmic) and excessive phagocytosis were seen in myofibers on electron microscopy. Glycogen was noted in endothelial cells in IOPD. Although PD accounts for a small fraction of muscle diseases, timely accurate diagnosis is imperative as it is treatable. Ultrastructural examination is necessary to confirm the diagnosis in cases with non-diagnostic light microscopic features, especially in adult LOPD patients.
Perovskite solar cells with CuSCN hole extraction layers yield stabilized efficiencies greater than 20%

Transporter layers improve stability Although perovskite solar cells can have power conversion efficiencies exceeding 20%, they can have limited thermal and ultraviolet irradiation stability. This is in part because of the materials used to extract the charge carriers (electrons and holes) from the active layer. Arora et al. replaced organic hole transporter layers with CuCSN to improve thermal stability. Device lifetime was enhanced when a conducting reduced graphene oxide spacer was added between the CuSCN layer and the gold electrode. Science, this issue p. 768 Thin CuSCN films can replace organic hole-transporting layers that limit thermal stability of devices. Perovskite solar cells (PSCs) with efficiencies greater than 20% have been realized only with expensive organic hole-transporting materials. We demonstrate PSCs that achieve stabilized efficiencies exceeding 20% with copper(I) thiocyanate (CuSCN) as the hole extraction layer. A fast solvent removal method enabled the creation of compact, highly conformal CuSCN layers that facilitate rapid carrier extraction and collection. The PSCs showed high thermal stability under long-term heating, although their operational stability was poor. This instability originated from potential-induced degradation of the CuSCN/Au contact. The addition of a conductive reduced graphene oxide spacer layer between CuSCN and gold allowed PSCs to retain >95% of their initial efficiency after aging at a maximum power point for 1000 hours under full solar intensity at 60°C. Under both continuous full-sun illumination and thermal stress, CuSCN-based devices surpassed the stability of spiro-OMeTAD–based PSCs.
Changes in the Inflammatory Potential of Diet Over Time and Risk of Colorectal Cancer in Postmenopausal Women

We examined the associations between changes in dietary inflammatory potential and risk of colorectal cancer (CRC) in 87,042 postmenopausal women recruited from 1993-1998 by the Women's Health Initiative, conducted in the United States. Food frequency questionnaire data were used to compute patterns of change in dietary inflammatory index (DII) scores and cumulative average DII scores over 3 years. Cox regression models were used to estimate hazard ratios for CRC risk. After a median of 16.2 years of follow-up, 1,038 CRC cases were diagnosed. DII changes were not substantially associated with overall CRC, but proximal colon cancer risk was higher in the proinflammatory-change DII group than in the antiinflammatory-stable DII group (hazard ratio = 1.32, 95% confidence interval: 1.01, 1.74). Among nonusers of nonsteroidal antiinflammatory drugs (NSAIDs) (Pinteraction = 0.055), the proinflammatory-stable DII group was at increased risk of overall CRC and proximal colon cancer. Also among nonusers of NSAIDs, risks of overall CRC, colon cancer, and proximal colon cancer were higher in the highest quintile compared with the lowest cumulative average DII quintile (65%, 61%, and 91% higher risk, respectively). Dietary changes toward, or a history of, proinflammatory diets are associated with an elevated risk of colon cancer, particularly for proximal colon cancer and among nonusers of NSAIDs.
Springback prediction of automobile body panel based on Yoshida-Uemori material model

Yoshida-Uemori kinematic hardening constitutive model can effectively describe the alterations of material properties under different deformation paths.In this paper,the forming process simulation and springback prediction of an automobile body panel is implemented by using JSTAMP/LS-DYNA.The Yoshida-Uemori constitutive model is selected to characterize the anisotropic material behavior of sheet metal during forming.Simulation predictions on spingback are compared with experimental results to demonstrate the effectiveness and accuracy of the Yoshida-Uemori model.The results indicate that the better springback prediction can be achieved by using Yoshida-Uemori constitutive model compared with orthotropic hardening constitutive models for high strength steel stamping.
The Role of Trait Emotional Intelligence in a Gender‐Specific Model of Organizational Variables

This article investigated the relationships between trait emotional intelligence ("trait EI" or "emotional self-efficacy") and 4 job-related variables (perceived job control, job stress, job satisfaction, and organizational commitment). Gender-specific data (N= 167, 87 females) were analyzed via multigroup structural equation modeling. Perceived job control had a negative effect on stress and a positive effect on satisfaction. Stress had a negative effect on satisfaction, which, in turn, had the strongest positive effect oil commitment. There were many gender differences in the model, mainly concerning age, which was negatively related to control and commitment in the female sample only. Trait El had specific, rather than widespread, effects in the model. Discussion focuses on trait EI's implications in the workplace.
Maize Dek37 Encodes a P-type PPR Protein That Affects cis-Splicing of Mitochondrial nad2 Intron 1 and Seed Development

Mitochondrial group II introns require the participation of numerous nucleus-encoded general and specific factors to achieve efficient splicing in vivo. Pentatricopeptide repeat (PPR) proteins have been implicated in assisting group II intron splicing. Here, we identified and characterized a new maize seed mutant, defective kernel 37 (dek37), which has significantly delayed endosperm and embryo development. Dek37 encodes a classic P-type PPR protein that targets mitochondria. The dek37 mutation causes no detectable DEK37 protein in mutant seeds. Mitochondrial transcripts analysis indicated that dek37 mutation decreases splicing efficiency of mitochondrial nad2 intron 1, leading to reduced assembly and NADH dehydrogenase activity of complex I. Transmission Electron Microscopy (TEM) revealed severe morphological defects of mitochondria in dek37. Transcriptome analysis of dek37 endosperm indicated enhanced expression in the alternative respiratory pathway and extensive differentially expressed genes related to mitochondrial function. These results indicated that Dek37 is involved in cis-splicing of mitochondrial nad2 intron 1 and is required for complex I assembly, mitochondrial function, and seed development in maize.
Tribological and corrosion behaviors of warm-and hot-rolled Ti-13Nb-13Zr alloys in simulated body fluid conditions

Development of submicrocrystalline structure in biomedical alloy such as Ti-13Nb-13Zr (in wt%) through warm-rolling process has been found to enhance mechanical properties compared to conventional thermomechanical processing routes including hot-rolling process. The present study investigated the tribological and corrosion behaviors of warm-rolled (WR) and hot-rolled Ti-13Nb-13Zr alloys which have not been studied to date. Both tribological and corrosion experiments were carried out in simulated body fluid conditions (Hank’s solution at 37°C) based on the fact that the investigated alloys would be used in a human body as orthopedic implants. The WR Ti-13Nb-13Zr demonstrated a submicrocrystalline structure that provided a significant enhancement in hardness, strength, and corrosion resistance. Meanwhile, there was no notable difference in wear resistance between the WR and hot-rolled samples despite the different microstructure and hardness. The present study confirmed the enormous potential of WR Ti-13Nb-13Zr with not only great mechanical properties but also high corrosion resistance in the simulated body fluid.
Nanofilled Resin Composite Properties and Clinical Performance: A Review.

The aim of this review was to compile recent evidence related to nanofilled resin composite materials regarding the properties and clinical performance. Special attention was given to mechanical properties, such as strength, hardness, abrasive wear, water sorption, and solubility. The clinical performance of nanocomposite materials compared with hybrid resin composites was also addressed in terms of retention and success rates, marginal adaptation, color match, and surface roughness. A search of English peer-reviewed dental literature (2003-2017) from PubMed and MEDLINE databases was conducted using the terms "nanocomposites" or "nanofilled resin composite" and "clinical evaluation. " The list was screened, and 82 papers that were relevant to the objectives of this work were included in the review. Mechanical properties of nanocomposites are generally comparable to those of hybrid composites but higher than microfilled composites. Nanocomposites presented lower abrasive wear than hybrids but higher sorption values. Their clinical performance was comparable to that of hybrid composites.
Inter‐disciplinary cooperation in a physician‐staffed emergency medical system

On‐scene management of pre‐hospital emergencies is often inter‐disciplinary, involving ground‐emergency medical services (EMS), police‐ and fire services, and in Norway general practitioners on‐call. This can also be supplemented by physician‐staffed EMS (P‐EMS), utilizing helicopters or rapid response vehicles. We hypothesized that P‐EMS cooperates extensively with other emergency services, and therefore the primary aim of this study was to investigate the fraction of inter‐disciplinary cooperation between P‐EMS and other emergency services.
Pathology and bacteria related to digital dermatitis in dairy cattle in all year round grazing system in Brazil

Digital dermatitis (DD) is one of the main causes of lameness in dairy cattle worldwide, and it is frequently reported in high-yielding, free stall dairy herds from regions with a temperate climate. However, DD is also observed with high prevalence in grazing cattle with a low milk yield in tropical regions. To clarify whether these differences have an impact on the etiology of the disease, we studied DD lesions from all year round grazing cattle of mixed breed in Brazil using high-throughput 16S rRNA gene sequencing and fluorescent in situ hybridization. The study included samples from 66 skin lesions and 5 healthy skins collected from five farms. Both techniques showed Treponema spp. to be the most abundant bacteria, present in all but one of the samples with minimal epidermal alterations. We identified eleven different Treponema strains belonging to the six major phylotypes of Treponema which have all previously been identified in DD lesions. Furthermore, we identify Dichelobacter nodosus in DD lesions by gene sequencing and also by fluorescent in situ hybridization in almost half of biopsy specimens in areas with mild epithelial damage and together with Treponema. The present data support the hypothesis that Treponema constitutes the main pathogen responsible for DD, independent of the environment and region where cows are kept, and it further suggests D. nodosus as another potentially important pathogen.
Aerosol indirect effect from turbulence-induced broadening of cloud-droplet size distributions

Significance Atmospheric aerosol concentration is linked to cloud brightness and lifetime through the modulation of precipitation. Generally speaking, larger cloud droplets and wider-droplet size distributions form precipitation more efficiently. We create steady-state clouds in the laboratory through a balance of constant aerosol injection and cloud-droplet removal due to settling. As aerosol concentration is decreased, the cloud-droplet mean diameter increases, as expected, but also the width of the size distribution increases sharply. Theory, simulations, and measurements point to greater supersaturation variability as the cause of this broadening in what can be considered a low aerosol/slow microphysics limit. The influence of aerosol concentration on the cloud-droplet size distribution is investigated in a laboratory chamber that enables turbulent cloud formation through moist convection. The experiments allow steady-state microphysics to be achieved, with aerosol input balanced by cloud-droplet growth and fallout. As aerosol concentration is increased, the cloud-droplet mean diameter decreases, as expected, but the width of the size distribution also decreases sharply. The aerosol input allows for cloud generation in the limiting regimes of fast microphysics (τcτt) for low aerosol concentration; here, τc is the phase-relaxation time and τt is the turbulence-correlation time. The increase in the width of the droplet size distribution for the low aerosol limit is consistent with larger variability of supersaturation due to the slow microphysical response. A stochastic differential equation for supersaturation predicts that the standard deviation of the squared droplet radius should increase linearly with a system time scale defined as τs−1=τc−1+τt−1, and the measurements are in excellent agreement with this finding. The result underscores the importance of droplet size dispersion for aerosol indirect effects: increasing aerosol concentration changes the albedo and suppresses precipitation formation not only through reduction of the mean droplet diameter but also by narrowing of the droplet size distribution due to reduced supersaturation fluctuations. Supersaturation fluctuations in the low aerosol/slow microphysics limit are likely of leading importance for precipitation formation.
Comparative Study on the Water Quality Parameters in Two Rural and Urban Rivers Emphasizing on the Pollution Level

3 Abstract: Water of Buriganga River, beside Dhaka and of a rural river Panguchi was studied and compared for pollution by determining various water quality parameters for one year. The river Buriganga is subjected to severe pollution whereas Panguchi is considered a less polluted river. The pH range is 6.69 to 8.14 for the river Buriganga and 6.90 to 8.80 for the river Panguchi. The organic pollution in river Buriganga is much more severe as indicated by DO (4.22 to 6.84) and BOD (0.97 to 3.12) than river Panguchi as the values are 7.16 to 8.66 and 5.43 to 5.73 respectively. The overall study shows that the degree of river pollution is quite alarming for the urban population.
