Intonation on trumpets

The purpose of this study was to determine the intonation properties of trumpets and to compare empirical data of played trumpets with a. ) theoretical tuning systems like equally tempered, Pythagorean tuning or just intonation and b. ) with the “objective intonation” which has been calculated by means of input impedance measurements. Another aim of this study was to evaluate the size of interand intra-individual variability in performances. Results show that there are great differences amongst players even playing the same reference instrument. The arithmetic mean over all trials correlates best with the equally tempered system. In the middle register, the calculated “objective intonation” matched played intonation even better.
The Effects of Exposure Intensity On Technology Adoption and Gains: Experimental Evidence from Bangladesh on the System of Rice Intensification*

We report the results of the first large-scale, multi-year experimental evaluation of the System of Rice Intensification (SRI), an innovation that first emerged in Madagascar in the 1980s and has now diffused to more than 50 countries. We find positive impacts of SRI on rice yields, profits, and various household well-being indicators. Using a randomized controlled trial with an innovative, multi-year, randomized saturation design, we find that greater cross-sectional or intertemporal intensity of exposure to the innovation has a sizable effect on Bangladeshi farmers’ propensity to adopt (and not to disadopt) SRI. There is significant spillover social learning by untrained farmers from trained farmers. But the biggest impacts on uptake and compliance with practices come through direct exposure, consistent with a complex contagion model of learning and technology diffusion. Average impacts of the technology, however, are invariant to exposure intensity, which seems to have mainly a scaling effect on diffusion of SRI, not an impact on performance with the technology. This finding appears most consistent with emerging models of multiple objective learning, as farmers quickly learn whether to adopt SRI but not necessarily how best to practice the method.
PREVALENCE AND CAUSE OF LOWER GASTROINTESTINAL BLEEDING IN ADULTS

Background: Lower gastrointestinal bleeding (LGIB) often presents a challenging clinical situation. Acute LGIB is defined as bleeding that emanates from a source distal to the ligament of Treitz, and the colonoscopy is well established as the diagnostic procedure of choice. Objective: To evaluate the results of colonoscopies performed to diagnose the cause of Acute Lower Gastrointestinal Bleeding (ALGIB) in the First Affiliated Peoples Hospital of Yangtze University at Jingzhou, Hubei, P.R. China. Materials and methods: Colonoscopy procedures performed in the Endoscopy service of the First Peoples Hospital of Jingzhou in those patients admitted due to ALGIB from February 2017 to January 2018 were analyzed retrospectively. The studied variables were age, gender, clinical presentations (such as pain abdomen, syncope, melena and hematochezia), colonoscopic findings, comorbidities (such as hypertension, coronary artery disease, diabetes mellitus, ischemic stroke, benign malignancy, liver cirrhosis, and gastrointestinal surgery history), smoking and alcohol intake history, along with use of anticoagulants, antiplatelets and NSAIDs (non-aspirin). Farhan Khan et al., IJSIT, 2018, 7(4), 799-813 IJSIT (www.ijsit.com), Volume 7, Issue 4, July-August 2018 800 Results: A total of 175 patients, 58.85% (n=103) were male and 41.15% (n=72) were female, who underwent colonoscopy examination for suspected ALGIB were reviewed retrospectively. The mean age of patient was (46.55±13.99), male: female ratio was 1.4:1. Of the total number of examinations performed, 10.28% (n=18) were normal. The colonic disease most often found in this study was Polyp 35.42% (n=62) followed by Inflammatory Bowel Disease 16.57% (n=29), Solitary Rectal Ulcer 8.57% (n=15), Unknown origin 8.57% (n=15), Hemorrhoids 7.42% (n=13), Growth 4.57% (n=8), Ischemic Colitis 3.42% (n=6), Diverticulosis 2.85% (n=5) and Vascular Ectasia 2.28% (n=4). The correlation between positive colonoscopy finding and age, smoking and alcohol intake history were statistically significant. Conclusion: ALGIB is common among middle aged (35-55 years) and old aged (56-80 years) group and the commonest cause is Polyp. The colonoscopy showed to be an effective diagnostic method in the case of ALGIB. Most patients respond to conservative therapy.
UvA-DARE ( Digital Academic Repository ) Fingermarks , more than just a ridge pattern

The chemical composition of a fingermark contains donor profiling information. Immunolabeling is a technique that can be used to retrieve this chemical information from fingermarks. Additionally, immunolabeling can be used to (re)develop fingermarks. To be of interest in the forensic field, the applicability of immunolabeling should be highly diverse. Therefore, in this study we investigated the applicability of one method of immunolabeling of fingermarks left on non-porous (aluminum foil, stainless steel keys, plastic sheets, different colored garbage bags, sandwich bags, Ziploc bags), semi-porous (tiles, laminated chipboard), and porous surfaces (thermal and copy paper). Successful immunolabeling of specific components in fingermarks was possible on all surfaces tested, except for laminated chipboards and copy paper. Additionally, high quality images could be obtained from the immunolabeled fingermarks. Surprisingly, fingermarks left on thermal paper showed improved visibility when developed with the immunolabeling method. In conclusion, one intrinsically similar immunolabeling method can visualize fingermarks left on non-porous, semi-porous and porous surfaces.
CFD analysis of a glider aircraft Using different RANS solvers and introducing improvements in the design

In this study, Computational Fluid Dynamics (CFD) simulations have been carried out in order to investigate and improve the performance of the Standard Cirrus glider, using different Navier-Stokes methods and solving the equations for the steady flow. The work has been divided in two parts: First, a study is performed to test the quality of the transition model (γ-Reθ). The two dimensional results of the glider ́s airfoil are compared against the results from panel’s methods and the open-source CFD codes: SU2 and OpenFoam. In addition, three dimensional glider ́s models are simulated using the transition model with the purpose of creating a validated reference model of the glider’s performance in steady level flight. The simulations are carried out in two dimensions for the outer wing airfoil for a 1.5 e + 06 Reynolds number and in three dimensions for the Wing & Fuselage model and Tail & Fuselage model under a range of velocities. Both simulations are validated against experimental data. In the second part of the study, the validated model is used to developed possible improvements in the glider ́s external geometry that could produce possible benefits in the performance and handling qualities of the glider.
Performance Of Flax Cultivars In Response To Exogenous application Of Salicylic Acid under Salinity Stress

Salicylic acid (SA) is an important signal molecule modulating plant responses to stress. Recently,it has been reported that it induces multiple stress tolerance in plants including salinity.Adverse effects of salinity (3000 and 6000 mg/l) on growth, some physiological responses and yield quantity and quality of two cultivars (Sakha 2 and Amon) of flax (Linum usitatissimum L.) plant were studied. Salt stress induced reduction in growth (length in cm, fresh and dry weight / plant in g of shoot and root) and indole acetic acid (IAA) content.While increased total phenol contents of plants of the two cultivars at 75 days old. Also, yield and yield components (technical and total shoot length in cm, and dry weight of shoot / plants in g) and fibre yield (fibre length (cm), fibre weight /plant (g), fibre % and straw yield /plant in g) were decreased except fibre % of Amon cultivar increased, as compared with those of control plants. In addition, cellulose % and cellulose/lignin % were decreased significantly meanwhile lignin % increased when compared with those of control plants. Foliar application of salicylic acid (SA) at 200 and 400 mg/l counteracted the adverse effect of salinity, this accompanied generally by significant increases in plant growth, IAA & phenol contents and yield components. Moreover, foliar treatment of salicylic acid(SA) resulted mostly in an increase in fibre yield when compared with those of the control plants and the corresponding salinity levels. In addition, cellulose% and cellulose/lignin% were increased significantly over control and the corresponding salinity levels plants meanwhile decreased lignin%.
Reproductive Health Needs of Adolescent and Adult Prison Inmates

Prisons are difficult but important areas to be accessed by non-governmental services. It is essential for the welfare of inmates (adolescents and adults) who have become a vulnerable population that they should be educated, treated and empowered. This paper is aimed to share the experiences of a collaborative study conducted by Disha Foundation (an NGO), government and prison agencies on the reproductive health issues of prisoners at Central Prison and in Borstal (juvenile prison) school at Nasik, Maharashtra, India. Reproductive health issues were the starting points for this project and the project addressed to the needs for empowerment, concerns about future and self-esteem of adolescents and adult prison inmates.
Default Options and Retirement Saving Dynamics

Does automatic enrollment in retirement savings plans increase lifetime wealth accumulation and welfare? I document that employees offset the short-run positive effect of automatic enrollment by saving less in the future. Consequently, a lifecycle model estimated on data from 34 U.S. 401(k) plans predicts that the long-term effect of auto-enrollment on wealth is negligible except at the bottom of the lifetime earnings distribution. The model’s long-run predictions are supported by its out-ofsample performance in predicting behavior in 86 other 401(k) plans and nationally representative U.K. data. The observed inertia at the savings default is explained by an opt-out cost of around $250. My estimate is smaller than the thousands of dollars estimated in previous studies because, in my fully dynamic model, non-autoenrolled workers can compensate for not contributing now by contributing more later. Automatic enrollment improves social welfare if the policymaker is more patient than individuals or puts more weight on low-income individuals’ utility. 1Choukhmane: Yale University to June 2019, NBER 2019-2020, MIT Sloan from July 2020 (taha.choukhmane@yale.edu).

The Influence of Moisture Content on Tensile and Compressive Strength of Artificially Cemented Sand

Applying Portland cement to soils is an excellent technique when it is necessary to improve local soil for the construction of stabilized pavement bases and to have a support layer for shallow foundations. Consoli et al. (2007, 2009, 2010) developed a rational dosage methodology for artificially cemented soils based on porosity/cement index, which can be applied to unconfined compressive strength, as well as to splitting tensile strength. Furthermore, a unique qt /qu relationship was found, independent of the cement content and voids ratio. Following the assessment of the main factors that influence the strength of artificially cemented soils, the present research aims to quantify the influence of the moisture content in the tensile and compressive strength of an artificially cemented sand. A program of splitting tensile tests and unconfined compression tests was carried out. There were tested three voids ratio (0.65, 0.73 and 0.81), four cement contents (3%, 5%, 7% and 9%) and five moisture contents (6%, 8%, 10%, 12% and 14%). The results show that the reduction in moisture content of the compacted mixture increases both the tensile and compressive strengths. Furthermore, it has been shown that qt /qu relationship was kept constant, being independent of the porosity/cement ratio and the moisture content.
Modulatory effect of Cardiospermum halicacabum extracts on TLR-2 in PBMC cells

Cardiospermum halicacabum leaves extract were investigated for their effect on expression of toll like receptor 2 (TLR-2) in Peripheral Blood Mononuclear Cells (PBMC) of healthy individual. Cell viability was not affected up to 30 μg of extract which was determined by tryphan blue dye exclusion method. TLR-2 mRNA expression was quantified by of Real time quantitative PCR technique. Ethanolic extract increased the TLR-2 expression by 2.7 fold whereas ethyl acetate extract reduced slightly. The results of the present study suggest that ethanolic extract of C. halicacabum contains lead compounds that could modulate the expression of toll like receptor which is normally expressed in peripheral blood mononuclear cells.
A CROSS-LANGUAGE COMPARISON OF VOT DEVELOPMENT IN ENGLISH- AND MANDARIN-SPEAKING CHILDREN AND ADOLESCENTS

Voice onset time (VOT) has been shown to vary with speaker’s sex, but current cross-language developmental studies lack the ability to explain how sex-specific speech patterns come about independent of a specific-language context. In this research, we examined Englishand Mandarin-speaking children and adolescents aged 6 to 17 to determine crosslanguage similarities and differences. VOT of wordinitial /t/ and /d/ was measured and normalized by vowel and word duration to control for speech rate. We found that in both languages, adolescent boys produced significantly longer VOT for /t/. No age or sex-related difference was found for /d/. The patterns are similar across the two languages. These results suggest that at least part of the sex-specific VOT patterns can be attributed to biological factors, and in our study, most likely anatomical differences that separate the two sexes in adolescence.
Determinants of Job Stress in Affecting Employees’ Life: A Study on the Malaysian Manufacturing Sector

Stress is one of the common challenges the employees may face or experience when they work anywhere in the world. The issue regarding work-related stress is one of the serious problems that are faced by workers in Malaysia. Besides, the demands of the contemporary work environment stress are common at the workplace. However, the physical and mental wellbeing of the employees can be jeopardized if the job stress is still uncontrollable. There are several factors of job stress, such as work overload, role conflict, role ambiguity, and workfamily conflict. The purpose of this study is to examine the relationship between the antecedents of job stress and job stress. A total of 113 manufacturing employees were surveyed through a self-administered questionnaire. The analysis revealed only three (3) predictors of job stress, namely work overload, role conflict, and role ambiguity were positive and significantly influenced job stress. Only the predictor of work-family conflict has no significant relationship with job stress. As role conflict is the most significant factor to job stress, it further proposed that it is essential for organizations to explain clearly to the employees their job role, job responsibilities, organization policies, and guidelines, organization expectations to help them to set a clear objective to contribute to the organizational success. Further, the manager needs to pay more attention to care about the amount of work given to reduce work-related stress and they must provide clear instructions to their subordinates about the tasks, duties, and responsibilities granted to the employees.
Predictive and Prognostic Factors in HCC Patients Treated with Sorafenib

Sorafenib is an oral kinase inhibitor that enhances survival in patients affected by advanced hepatocellular carcinoma (HCC). According to the results of two registrative trials, this drug represents a gold quality standard in the first line treatment of advanced HCC. Recently, lenvatinib showed similar results in terms of survival in a non-inferiority randomized trial study considering the same subset of patients. Unlike other targeted therapies, predictive and prognostic markers in HCC patients treated with sorafenib are lacking. Their identification could help clinicians in the daily management of these patients, mostly in light of the new therapeutic options available in the first.
PAEDIATRIC HIV-LOOKING BEYOND CD 4 COUNTS Correspondence

Correspondence Author: Joanne Potterton PhD Department of Physiotherapy, Faculty of Health Sciences, University of the Witwatersrand, 7 York Road Parktown 2193 Johannesburg, South Africa Email: Joanne.potterton@wits.ac. za ABSTRACT: Paediatric HIV remains a significant health and social challenge in sub-Saharan Africa despite many countries gaining improved access to antiretroviral treatment. Paediatric HIV affects multiple body systems and has the potential to cause wide ranging impairments as well as activity and participation limitations. The aim of this paper is to highlight some of the impairments that remain, despite the children having access to better medical care, in order to establish a possible role for physiotherapists. Nine studies conducted through the department of physiotherapy at the University of the Witwatersrand, South Africa are presented. The results of these studies demonstrate the neurodevelopmental, musculoskeletal, respiratory and quality of life challenges which children infected with HIV as well as their caregivers continue to face. The need for long term, multidisciplinary follow up of children infected with HIV is emphasized.
Flag versions of quiver Grassmannians for Dynkin quivers have no odd cohomology over Z

We prove that ﬂag versions of quiver Grassmannians (also knows as Lusztig’s ﬁbers) for Dynkin quivers (types A , D , E ) have no odd cohomology over Z . Moreover, for types A and D we prove that these varieties have α -partitions into aﬃne spaces. We also show that to prove the same statement for type E , it is enough to check this for indecomposable rep-resentations.Wealsogive a ﬂag version of the result of Irelli-Esposito-Franzen-Reineke on rigid representations: we prove that ﬂag versions of quiver Grassmannians for rigid representations have a diagonal decomposition. In particular, they have no odd cohomology over Z .
Do 3-to 4-year-old Mandarin-English bilinguals separate long-lag VOTs in these two languages ?

Previous research has reported that Mandarin and English both have short-lag and long-lag VOTs in similar regions along the VOT continuum. However, Mandarin long-lag VOTs are longer than English long-lag VOTs in adults. The present study examined whether 3to 4-year-old bilingual Mandarin-English children and corresponding monolingual children demonstrate the subtle but noticeable language difference that adult speakers do. The participants included 10 bilingual MandarinEnglish children, 20 corresponding monolingual children, and 22 corresponding monolingual adults. The speech materials included 9 Mandarin words containing three Mandarin aspirated stops and/or 9 English words containing three English voiceless stops. The VOT values were measured using Adobe Audition 1.0. The results showed that unlike adults, the monolingual children and bilingual children at this young age did not show the language difference on long-lag VOTs. However, the VOT patterns were different in the bilingual children who differed in the amount of experience in English.
Long-term memor ies in Latin Amer ican stock markets

Understanding stock markets price fluctuations is an important role in financial economics policy, corporate investment and financing strategies. The more efficient is the market, the more random is the sequence of price changes generated by the market. Therefore, the existence of long memory in stock market returns would affect the investment horizon of portfolio decisions. This study provides a detailed examination of long-range dependence in weekly returns for the seven markets of Latin America from 1994 to 2005. The results provided from the BDS and K2K tests suggest the existence of nonlinear dependence in the returns series in all the analyzed countries. Also was evidenced random walk behavior for two markets and for the five other markets, the value the DFA test is smaller, which helps on the affirmative that the participation of long-range dependence in the formation of the prices weekly is minimum.
Improving Aggregation and Loss Function for Better Embedding Learning in End-to-End Speaker Verification System

Deep embedding learning based speaker veriﬁcation (SV) methods have recently achieved signiﬁcant performance improvement over traditional i-vector systems, especially for short duration utterances. Embedding learning commonly consists of three components: frame-level feature processing, utterance-level embedding learning, and loss function to discriminate between speakers. For the learned embeddings, a back-end model ( i.e. , Linear Discriminant Analysis followed by Probabilistic Linear Discriminant Analysis (LDA-PLDA)) is generally applied as a similarity measure. In this paper, we propose to further improve the effectiveness of deep embedding learning methods in the following components: (1) A multi-stage aggregation strategy, exploited to hierarchically fuse time-frequency context information for effective frame-level feature processing. (2) A discriminant analysis loss is designed for end-to-end training, which aims to explicitly learn the discriminative embeddings, i.e. with small intra-speaker and large inter-speaker variances. To evaluate the effectiveness of the proposed improvements, we conduct extensive experiments on the VoxCeleb1 dataset. The results outperform state-of-the-art systems by a signiﬁcant margin. It is also worth noting that the results are obtained using a simple cosine metric instead of the more com-plex LDA-PLDA backend scoring.
