Minakawaite and platinum–group minerals in the placer from the clinopyroxenite area in serpentinite mélange of Kurosegawa belt, Kumamoto Prefecture, Japan

Minakawaite, a new mineral with a RhSb composition, in association with a platinum–group mineral (PGM) placer is found from a small stream crossing the clinopyroxenite mass in serpentinite mélange of the Kurosegawa belt on the northeast side of Hikawa Dam, Haraigawa, Misato machi, Kumamoto Prefecture, Japan. Almost all PGM placer grains are based on isoferroplatinum, of which the rims are often covered by tulameenite and tetraferroplatinum. This isoferroplatinum–based grain contains small inclusions and accessories consisting mainly of osmium, erlichmanite, laurite, bowieite, cuprorhodsite, and ferhodsite–like mineral. Minakawaite occurs as the outmost surface layer with a rose gray metallic luster on the nub consisting of cuprorhodsite, ferhodsite–like mineral and/or Rh(Ge,Cu,Fe) mineral in association with an isoferroplatinum–based grain. The density of minakawaite is 10.04 g/cm3, calculated using the empirical formula and powder X–ray diffraction (XRD) data. Minakawaite has a pale gray color under the microscope in reflected light, and pleochroism is weak as a variation from pinkish pale gray to bluish pale gray. Anisotropy is moderate as reddish gray to bluish gray. Average results of ten energy dispersive X–ray spectroscopy (EDS) analyses give Rh 46.83, Sb 48.97, As 4.08 and total 99.88 wt%. The empirical formula is Rh0.998(Sb0.882As0.120)Σ1. 002, based on 2 atoms per formula unit. Minakawaite is orthorhombic (Pnma) with a = 5.934(7) Å, b = 3.848(3) Å, c = 6.305(4) Å, and V = 144.0(2) Å3 (Z = 4). The seven strongest lines of minakawaite in the powder XRD pattern [d in Å(I/I0) (hkl)] are 2.860(63) (111), 2.774(35) (102), 2.250(47) (112), 2.199(100) (211), 2.162(38) (202), 1.923(49) (020), and 1.843(51) (013). Minakawaite is identical to the synthetic RhSb phase with MnP–type structure. PGM including minakawaite may occur with chromite in the magma chamber of the clinopyroxenite. Minakawaite was named in honor of Japanese mineralogist, Prof. Tetsuo Minakawa (b. 1950) of Ehime University for his outstanding contribution to descriptive mineralogy from Kyushu and Shikoku, Japan.
Selective laser melting and sintering technique of the cobalt-chromium dental alloy

Introduction/Objective. The objective of this paper is to describe the microstructure and mechanical properties of sintered Co-Cr alloy and to emphasize its advantages and disadvantages with respect to the microstructure and mechanical properties of cast Co-Cr alloy. Methods. Base Co-Cr alloy, EOSint M EOS Co-Cr SP2 (EOS GmbH, Munch, Germany), was used for the purpose of this research as the base material for sintering metal structures of metal-ceramic restorations. Metal sintering was conducted by using EOSint M 280 device of German origin in a stream of neutral gas ? argon. After that, the alloy was heated over a period of 20 minutes at the temperature of 800? C. The chemical composition of the alloy was determined by energy dispersive spectroscopy. Microstructure of the tested alloy samples was examined under an optical metallographic and scanning electron microscope. Physical and mechanical properties were measured in a universal testing machine. The samples were prepared according to the standard ISO 527-1:1993. Results. Chemical composition of the sintered Co-Cr alloy, determined by applying energy dispersive spectroscopy, indicated the same qualitative but different quantitative composition compared to cast Co-Cr alloys. The microstructure of the sintered Co-Cr alloy is lamellar in nature, with two dominant phases: ? -Co and/or ? -Cr (fcc ? face-centered cubic) and ? -Co (hcp ? hexagonal close-packed). Mechanical properties of the Co-Cr alloy obtained by applying selective laser melting technology compared to the cast Co-Cr alloy are superior or approximately the same. Conclusion. Selective laser melting of the Co-Cr alloy is a good example of new technologies based on digitization. Together with other digitized procedures, this technology is an introduction to a new era in dentistry popularly called Dentistry 4.0. The advantages of the selective laser melting technology with respect to the conventional technology of casting Co-Cr alloy metal structures are precise metal structure fitting and eco-friendly technology.
A contamination model for approximate stochastic order.∗

Stochastic ordering among distributions has been considered in a variety of scenarios. Economic studies often involve research about the ordering of investment strategies or social welfare. However, as noted in the literature, stochastic orderings are often a too strong assumption which is not supported by the data even in cases in which the researcher tends to believe that a certain variable is somehow smaller than other. Instead of considering this rigid model of stochastic order we propose to look at a more flexible version in which two distributions are said to satisfy an approximate stochastic order relation if they are slightly contaminated versions of distributions which do satisfy the stochastic ordering. The minimal level of contamination that makes this approximate model hold can be used as a measure of the deviation of the original distributions from the exact stochastic order model. Our approach is based on the use of trimmings of probability measures. We discuss the connection between them and the approximate stochastic order model and provide theoretical support for its use in data analysis, including asymptotic distributional theory as well as non-asymptotic bounds for the error probabilities of our tests. We also provide simulation results and a case study for illustration. ∗Research partially supported by the Spanish Ministerio de Ciencia y Tecnoloǵıa, grants MTM201128657-C02-01 and MTM2011-28657-C02-02, and by Consejeŕıa de Educación de la Junta de Castilla y León, grant VA212U13.
Microbial Fuel-Cells Electricity Production from Carbohydrates

Microbial fuel cells containing Proteus vulgaris and oxidationreduction ("redox") mediators were investigated. The bacteria were chemically immobilized onto the surface of graphite felt electrodes, which supported production of continuous electric current and could be reused after storage. A computer-controlled carbohydrate feed system enabled the cell to generate a constant output with improved efficiency compared to the performance obtained with single large additions of fuel. The response to additions of substrate when immobilized bacteria were used was faster than that achieved with freely suspended organisms. This is attributed to the advantageous masstransfer kinetics resulting from the proximity of the immobilized bacteria and the electrode surface. Index Entries: Microbial fuel cell; mediator; immobilization; computer control; bioanode.
Teacher professionalization in relation to retention strategies Do teacher training activities have any impact on drop-out rates in adult education?

This paper reports some preliminary findings of a research project titled New roles for the teacher Increased completion through social responsibility. This research, designed as an intervention project, has an overall aim of reducing absence and dropout rates in the Danish vocational and general adult educational system by developing and improving the teachers’ competences. This has been pursued in the research project through engaging teachers in training aimed at improving their sociopedagogical competences. The effect of this training has been measured by two electronic questionnaires filled in by the teachers, interviews with the teachers, and by the teachers’ written logbooks. At this stage of the research it is not possible to document comprehensive and specific changes in the teachers' attitudes and specific behaviour. However the project’s focus on the socio-pedagogical competence has had an impact on the drop-out rate. The preliminary conclusion is that it is the general attitude in the teacher groups towards the importance of improving retention that is of significance for the documented effects on the drop-out rates.
Residues of invasive forage species inhibits the growth of Caryocar brasiliense 2

Native species seedling growth may be affected by allelopathic substances released by invasive forage species, mainly in natural regrowth areas. Thus, this research aimed to evaluate the growth characteristics of pequi trees influenced by concentrations of plant residues of different forage species (Urochloa decumbens, Melinis minutiflora and Paspalum notatum). A randomized block experimental design was arranged in a factorial 3 x 4 + 1, with four replications. Treatments consisted of incorporating plant shoot residues of three forage species to pequi seedling substrate (soil + fertilizer) at four concentrations (1%, 2%, 3%, and 4% mass/mass), plus pequi seedlings grown in a residue-free substrate (control). Pequi plant height, stem diameter, and leaf number were evaluated at fortnightly intervals. Leaf area, root/shoot ratio, leaf area ratio, specific leaf area, and leaf mass ratio were determined 100 days after transplanting. Forage residues added to substrate inhibited pequi growth, and with increasing residue concentration, this inhibition was intensified. Pequi leaf characteristics proved to be more sensitive to allelopathic effect, especially from U. decumbens residues.
N ° 2011-8 Productivity , Capital and Labor in Labor-Managed and Conventional Firms

Despite a continuing interest in the compared efficiency of labor-managed and conventional firms, only a handful of comparative empirical studies exist. These studies suggest that labor-managed firms have the same productivity levels as conventional ones, but organize production differently. However, the data used in these studies cover a single industry, or firms matched by industry and size in manufacturing, and concern a few dozen firms. In addition, the use of constant-elasticity production functions in past studies has made it difficult to distinguish the effects of incentives embodied in the factors of production from those of scale differences that could be caused by the differences in factor demand behavior between conventional and labor-managed firms hypothesized by economic theory. The paper compares the productivity of labor-managed and conventional firms using two new panel data sets covering several thousand firms from France, including representative samples of conventional firms and all worker cooperatives with 20 employees or more in manufacturing and services. We present Generalized Least Squares (GLS) and Generalized Moments Method (GMM) estimations of translog production functions industry by industry for cooperative and conventional firms and test for the equality of their total factor productivities. We also allow systematic differences in scale and technology to be determined by the ownership form. The translog specification, which allows returns to scale to vary with input levels, makes it possible to disentangle embodied incentive effects from systematic differences in scale due to underinvestment in labor-managed firms. In the process, we also propose updated “stylized facts” about labor-managed firms in comparison with conventional firms. Our production function estimates suggest that cooperatives are at least as productive as conventional firms. However, the two types of firms organize production differently. Cooperatives are more X-efficient, i.e., they use their capital and labour more effectively, than conventional firms. With their current levels of inputs, cooperatives produce at least as much with the technology they have chosen as they would if they were using conventional firms’ technology. In contrast, in several industries conventional firms would produce more with their current inputs if they were organizing production as cooperatives do. In all industries and in both data sets, both types of firms would produce at constant or decreasing returns to scale if they were using the same technology at their current input levels, and we find no evidence that returns to scale are systematically higher in cooperatives. Contrary to received wisdom, descriptive statistics indicate that workers’ cooperatives are not always smaller or less capitalized than conventional firms, and grow at least as fast as conventional firms in all the industries studied.
Relationships Between Cognitive Engagement and Self-Efficacy for High School Students Who Participate in Service-Learning

The purpose of this explanatory quantitative case study was to examine the relationship between service-learning, cognitive engagement, and self-efficacy for high school students. The study was conducted at a high school located in North Carolina. Fifty-one students in grades 10 to 12 participated in the study. All students in the study had participated in at least one service-learning activity before the study. Data was collected using the Service-Learning, Cognitive Engagement, and Self-Efficacy Questionnaire (SLCESEQ) which included items from (a) the Control and Relevance of Schoolwork subscale of the Student Engagement Instrument to measure the cognitive engagement and (b) the General Self-Efficacy Scale to measure self-efficacy. Also, respondents self-reported the demographics (race/ethnicity, gender, and grade level) as well as the number and type of service-learning activities in which they had participated. Data analysis did not yield statistically significant relationships between the service-learning, cognitive engagement, and self-efficacy). However, there were several statistically significant relationships between cognitive engagement and self-efficacy. In addition, the demographic variables had significant relationships with cognitive engagement and self-efficacy.

Preliminary study of constipation after posterior sagittal anorectoplasty

Objective Constipation is a major complication after posterior sagittal anorectoplasty(PSARP) for imperforate anus. Although anomalous innervation patterns of the rectal pouch in clinical studies, the innervation patterns of the rectal pouch in rats have not been reported. The aim was to study the innervation patterns of the rectal pouch in rats and correlate this to the cause of constipation after PSARP. Methods 12 mature Wistar-Imamichi rats, aged from 2 to 3 months, weighing 250 to 300? g, were used in this experiment. The rats were mated. The presence of sperm in the vaginal smear signifies gestation day one. Eight pregnant rats were divided into experiment (5) and control (3) groups. Gavage with ethylenethiourea (ETU, 1% 125? mg/kg) and distilled water were carried out on gestation day 11 for experiment and control groups respectively. 33 fetuses with imperforate anus and 31 in control were harvested by Cesarean section on gestation day 22.Serial sagittal sections were performed on fetuses and were HE stained. The slides were labelled with specific antibodies (Neuron Specific Enolase, S-100), intestinal internal neurons and glial cells were counted and compared with those of the controls. Results Photomicrograph of the midsagittal section in fetuses with imperforate anus showed rectal pouch. The amounts of myenteric neurons in rectal pouch and normal rectum were 2.09± 0.50 and 2.74± 0.51 respectively. The amounts of submucous neurons in rectal pouch and normal rectum are 0.72± 0.37 and 1.34± 0.37 respectively. The amounts of neurons in rectal pouchs were less than control (P 0.01). The glial cells in rectal pouches showed no difference to that of control.Conclusions The decrease of neurons in rectal pouchs may be the cause of dysfunction of rectum and the cause of constipation after PSARP.
Effects of Depression History and Sex on the Efficacy of Sequential Versus Standard Fluoxetine for Smoking Cessation in Elevated Depressive Symptom Smokers

Objective:The potential benefits of antidepressant pharmacotherapy with fluoxetine for smoking cessation among vulnerable subpopulations of depressed smokers have not been well explored. This study examined whether the efficacy of a sequential course of fluoxetine for smoking cessation differed as a function of depression history (none vs. single vs. recurrent episodes) and sex. Methods:Data were from a randomized controlled trial that evaluated the efficacy of sequential fluoxetine treatment (SEQ-FLUOX; 16 wk, starting 8 wk prequit) in comparison with standard fluoxetine treatment (ST-FLUOX; 10 wk, starting 2 wk prequit) and transdermal nicotine patch only (TNP) for 216 smokers with elevated depressive symptoms. Results:Cox regression analyses revealed significant moderating effects of depression history (recurrent vs. single), but not sex, on the efficacy of SEQ-FLUOX versus ST-FLUOX on latency to relapse. Among smokers with recurrent major depressive disorder (MDD) episodes, those receiving SEQ-FLUOX were slower to relapse, compared with those receiving ST-FLUOX, but not relative to TNP. No such treatment difference was observed in smokers with no MDD history or a single past MDD episode. Furthermore, those with recurrent MDD receiving SEQ-FLUOX reported significantly lower levels of depressive symptoms over 26 weeks after quitting, compared with those receiving ST-FLUOX, but not relative to TNP. Conclusions:Findings suggest the possible specific benefits of treating elevated depressive symptom smokers with recurrent MDD using fluoxetine in a sequential manner (vs. standard). However, given the small sample size, the reliability of this difference is unknown. Replication with a larger sample of recurrent MDD history is needed.
Upregulation of vimentin and aberrant expression of E-cadherin/beta-catenin complex in oral squamous cell carcinomas:correlation with the clinicopathological features and patient outcome

Oral squamous cell carcinoma is a challenging oncology problem.A reliable biomarker for metastasis or high-risk prognosis in oral cancer patients remains undefined.Using quantitative immunohistochemistry,we examined the expression of vimentin,E-cadherin,and beta-catenin in 83 oral squamous cell carcinoma patients,and the relationships between the expression of these markers and specific clinicopathological features were analysed.The high expression of vimentin was observed in 23 of 43(53%) tumours from patients who eventually developed a recurrent tumour and was associated with recurrence and death(P 0.001 and 0.001,respectively). The decreased expression of E-cadherin was observed in 36 of 43(84%) tumours from patients who eventually developed a recurrent tumour and was also associated with recurrence and death(P 0.001 and 0.001,respectively). Although no correlation between beta-catenin expression in whole-tumour sections and clinicopathological features was observed,decreased beta-catenin expression at the tumour invasive front was closely associated with recurrence and death(P=0.002 and 0.002,respectively). The expression of vimentin and that of E-cadherin were associated with survival and were independent prognostic factors in univariate and multivariate analyses.Our data show that the overexpression of vimentin was closely associated with recurrence and death in oral squamous cell carcinoma patients.The combination of the upregulation of vimentin and aberrant expression of E-cadherin/beta-catenin complexes at the tumour invasive front may provide a useful prognostic marker in oral squamous cell carcinoma.
Electronic Medical Records vs. Electronic Health Records:Yes,There Is a Difference

The paper started from the definition of EMR and EHR, using the EMR Adoption Model created by HIMSS, scored the approximately 4,000 hospitals in HIMSS database relative to their EMR status. The majority of US hospitals are in the early stage of EMR adoption. There is still a long way to go to use EMR in order to achieve the higher EHR stage.
Proliferation marker Ki-67 in early breast cancer

Molecular markers have been extensively investigated with a view to providing early and accurate information on long-term outcome and prediction of response to treatment of early breast cancer.Proliferation is a key feature of the progression of tumors and is now widely estimated by the immunohistochemical assessment of the nuclear antigen Ki-67.The expression of Ki-67 correlates with other measurements of proliferation,including S-phase and bromodeoxyuridine uptake.High Ki-67 is a sign of poor prognosis associated with a good chance of clinical response to chemotherapy,but its independent significance is modest and does not merit measurements in most routine clinical scenarios.
Body Weight Support Assisted Virtual Reality based Treadmill Walk with Gait Characterization

Healthy community living is adversely affected with post-stroke gait disorder. Patients are referred to gait rehabilitation. Often, clinician characterizes their gait using observation-based techniques. Though powerful, this suffers from subjectivity, resource limitations, etc. In rehabilitation, patients undergo over-ground and treadmill-based exercises. Treadmills augmented with cameras can quantify one's gait and offer rehabilitation. However, camera-based techniques are costly, lack portability, etc. Again, to ensure safety and unweighing (by varying degrees), treadmill-based setups are coupled with body weight support (BWS). Often this comes with Virtual Reality (VR)-based audio-visual motivational feedback. Here, we have designed BWS-assisted VR-enabled treadmill-based gait exercise platform. Additionally, we have used instrumented shoes to measure gait-related parameters e.g., stance and swing phases, symmetry index, etc. The results of a study with seven healthy and two post-stroke participants indicate the feasibility of the platform to have implications on gait and potential to contribute to post-stroke gait rehabilitation.
