Wind-tunnel tests of a helicopter rotor with active flaps

Within the frame of a project called DTP RPA (Développement Technique Probatoire Rotor à Pale Active), also known as Active Blade Concept, carried out in cooperation between ONERA, Eurocopter, DLR and Eurocopter Deutschland, a four-bladed Mach-scaled rotor was tested in December 2005 in ONERA S1 Modane wind-tunnel. The main objective of this test was to validate the concept of using active flaps located on the trailing edge of the blades of the main rotor of a helicopter to decrease the vibration level generated by this rotor. The present paper gives a general description of the experimental setup which allowed testing the active flap-equipped rotor including the control strategy, as well as first significant results related to aerodynamics, aero-acoustics and dynamics of such a rotor, showing the efficiency of active flaps with respect to the objectives of the study.
Morphological aspects of the fracture healing process in diabetic rats

This experiment aims to investigate the morphological aspects of fracture healing in diabetic rats (at one-, two-, four-, and six-week controls). Wistar rats (Rattus norvegicus albinus) were divided into Control and Diabetic groups. Diabetes was induced via intraperitoneal injection of streptozotocin. Closed tibial fractures were produced after antegrade intramedullary fixation. Histologically, quantitative and qualitative changes were observed in the Diabetic group. After six weeks, the Control group showed complete fracture healing, whereas the diabetic rats showed incomplete fracture healing. There was no radiographic difference between the groups. Under such controlled experimental situation, the authors conclude that bone healing in internally fixed closed tibial fractures of Wistar rats may be delayed by diabetes acute changes.

EVALUATION OF ULTIMATE DEFORMATION CAPACITY AT AXIAL LOAD COLLAPSE OF REINFORCED CONCRETE COLUMNS

Two series of tests were conducted on scaled reinforced concrete columns. In the first series, lateral loading was common for all specimens. Selected parameters were concrete strength and applied axial load: constant and varying ones. In the second series, axial load was common for all specimens. Selected parameters were shear span ratio, transverse reinforcement ratio and lateral loading simulating: near and far field earthquakes. Results from the first test series concluded that axial load type and magnitude affect columns’ lateral deformation capacity, shear degradation and axial stiffness. Results from the second series concluded that lateral loading type has, in some cases, no influence on the lateral or axial deformability of columns, especially when the amount of transverse reinforcement is low. Therefore, in some other cases, shear strength evolution is affected by lateral loading type.
Magnitude of Neonatal Mortality and associated factors among Neonates at Arba Minch General Hospital

Background: Newborns are the future generations and ensuring their healthy growth and development and all the activities regarding them must be the prime concern of societies. The Ethiopian government has used a combined efforts and interventions in health promotion, nutrition, and non-health sectors at different levels to reduce neonatal mortality but still has high neonatal mortality. The objective of this study was to assess the magnitude of neonatal mortality and associated factors among Neonates admitted in neonatal intensive care unit of Arba Minch general hospital. Method: A cross sectional study was conducted from January, 01, 2015 to December, 31, 2017 G.C in Arba Minch General Hospital. Simple random sampling technique using computer generated random numbers was used to recruit the predetermined 332 samples. Data were collected using structured checklist and entered, coded, edited and cleaned using Epi-info version 7 and exported to SPSS version 23 for Windows. Crude and Adjusted Odd ratio, 95% CI and P-value were used to assess the strength of association and statistical significance. Variables which have p value <0.05 were declared as significant.

The 5th minute APGAR score less than five (AOR:4.4; 95%CI: 1.98,9.65), Induced labor (AOR:2.7; 95%CI: 1.03,7.37), Duration of labor > 18 hour (AOR:2.6; 95%CI: 1.12,6.11), Time of rupture of membrane >12 hour (AOR:3.9; 95%CI: 1.5,9.87) and Birth order > (AOR:19.5; 95%CI: 6.84,55.45) were the independent factors which cause neonatal mortality. Conclusion: The magnitude of neonatal mortality was high and the fifth minute APGAR score less than 5, Induced labor, Duration of labor more than or equal to 18 hours, Time of rupture of membrane more than or equal to 12 hours before delivery and being fifth or above birth order are the independent factors which cause neonates to die.
Factors influencing prospective international students ’ motivation for overseas study and selection of host countries and institutions : The case of Vietnamese students

International students have been found to contribute a great deal to their host institution and country in terms of socio-economic and cultural development; as a result, recruiting international students has become an important strategy for sustaining institutional and national development. Recent studies have discovered an increasingly intense competition between Asian and Western higher education providers to enroll more international students. Existing literature also suggests that international students’ choice of host country and/or institution is influenced by numerous different factors, heavily dependent on their backgrounds.
Association between patient-reported measures of psychological distress and patient satisfaction scores after spine surgery.

BACKGROUND Patient satisfaction has become an important component of the delivery of health care in the United States. Previous studies have shown that patient satisfaction is influenced by patient-specific characteristics. The goal of this study was to determine whether psychological distress influences outpatient satisfaction scores following spine surgery. METHODS We retrospectively reviewed the records from all outpatient clinical encounters at a single academic spine surgery center between February 2011 and January 2013. Any patient who completed both a patient satisfaction survey and a Distress and Risk Assessment Method (DRAM) questionnaire for the same clinical encounter was included in the study. Statistical analysis was performed to determine whether patient satisfaction scores were influenced by psychological distress. RESULTS During the study period, 103 patients who met the inclusion criteria were identified. On the basis of their responses to the DRAM questionnaire, fifty-six were classified as normal (no evidence of distress), twenty-two as at risk, thirteen as distressed depressive, and twelve as distressed somatic. The mean overall patient satisfaction scores (and standard deviation) were 90.2 ± 10.9 in the normal group, 94.7 ± 8.2 in the at-risk group, 87.5 ± 16.2 in the distressed-depressive group, and 75.7 ± 22.4 in the distressed-somatic group (p = 0.003). The mean score for the patients' satisfaction with their provider was 94.2 ± 12.0 in the normal group, 94.2 ± 9.5 in the at-risk group, 90.6 ± 24.0 in the distressed-depressive group, and 74.9 ± 26.2 in the distressed-somatic group (p = 0.011). CONCLUSIONS These results indicate a significant association between patient satisfaction and psychological distress as measured with the DRAM questionnaire. "Distressed" patients gave significantly lower scores for overall satisfaction and satisfaction with their provider compared with patients categorized as "normal. " These results suggest that psychological factors may influence patients' perception of the medical care provided to them.
A proposed staging for children with neuroblastoma. Children's cancer study group A

A clinical staging of patients with neuroblastoma is proposed. Such staging is desirable to aid in estimating the prognosis and to be able to evaluate the efficacy of differing therapeutic regimens by analyzing results obtained in comparable groups of patients. That the suggested staging is practical is illustrated by the ease with which 100 children with neuroblastoma, entered in previous studies by Children's Cancer Study Group A, were staged using the criteria described. Short‐term survival data of this small sample demonstrated, in addition, that the proposed staging appears to be of help in estimating the prognosis. Also proposed is a list of investigations which aid in accurate staging.
PR ] 2 7 M ay 2 01 9 Random attractors for rough differential equations

We apply the unified approach in [10] to study the asymptotic behavior of rough differential equations, which consists of two steps of applying the continuous and discrete Gronwall lemmas. The existence of the global pullback attractor for the generated random dynamical system is then proved. We also derive an estimate for the diameter of the global attractor, and prove that for the linear diffusion function of linear form, the pullback attractor collapses to a random point.
Teach to comply ? Evidence from a taxpayer education program in Rwanda DRAFT – please do not cite or circulate without permission

The role of taxpayer education in improving tax compliance has been largely unexplored in the literature. This paper starts filling this gap by providing the first rigorous evaluation of the effectiveness of taxpayer education on knowledge, perceptions, and compliance in Rwanda – or in any other country. Our analysis is based on a unique dataset that combines administrative and survey data. We show that taxpayer education results in significant and large increases in knowledge, which starts from a very low level at baseline. We also show that the program contributes to improve compliance behaviour. Our strongest result is that training new taxpayers helps bringing them into the habit of filing tax declarations – an obligation many fail to comply with. In terms of policy, our results show that the benefits of taxpayer education go beyond increased revenue in the short term, and include building a habit of tax compliance.

Furthermore, the path analysis result demonstrates that usage attitude is the most significant factor for customer satisfaction, and the .
Comparison of outpatient utilization of psychopharmaceuticals between Croatia and Scandinavian countries ( 2001-2003 )

Neurotropic drugs account for 15% of total drug utilization in Croatia. The aim was to estimate outpatient consumption of psychotropic drugs in Croatia in correlation with Scandinavian countries. Data on drug utilization in Croatia were collected and analyzed for the 2001-2003 period. Data were obtained from Zagreb Municipal Pharmacy and extrapolated to the total number of pharmacies. All drugs were classified according to AnatomicalTherapeutic-Chemical (ATC) drug classification system. These data were used to calculate a number of defined daily doses (DDD) and DDD per 1000 inhabitants per day (DDD/TID). Data of the Nordic Medico-Statistical Committee were used for Scandinavian countries. In Croatia, total utilization of psychopharmaceuticals of 144.9 DDD/TID in 2001, 148.9 DDD/TID in 2002 and 141.9 DDD/TID in 2003 exceeded that recorded in Scandinavian countries. Anxiolytics accounted for 90% of psycholeptic utilization in Croatia versus 22% in Sweden and 34% in Finland. The anxiolytic/antidepressant ratio decreased in Croatia by 35.19% (7.19 in 2001 and 4.66 in 2003), whereas in Scandinavian countries it showed a constant rate (0.7 in Finland, 0.4 in Denmark and Norway, and 0.3 in Sweden). In Croatia, benzodiazepines accounted for 86.9% of psychopharmaceutical utilization, pointing to the need of respective guidelines as a measure of rationalization.
The frequency of hyperuricemia with left ventricular hypertrophy in patient with primary hypertension in Erbil city-Iraq

Background: High serum uric acid level is common in hypertension and it may be correlated with left ventricular hypertrophy. The frequency of hyperuricemia is not previously well investigated in Erbil city. Objectives: The objective of this study was to investigate the frequency of hyperuricemia and the association between serum uric acid levels and left ventricular hypertrophy in a group of hypertensive patients in Erbil-Iraq. Patients and methods: A cross-sectional study was conducted in Rizgary teaching hospital between September 2015 and September 2016. A total of 150 consecutive adult patients presenting with primary hypertension were included. Based on the results of the echocardiography, the patients were classified into two groups; Group I (patients with left ventricular hypertrophy) and Group II (patients with nonleft ventricular hypertrophy). The effects of high serum uric acid level on left ventricular mass and geometry were evaluated in both groups. Results: High serum uric acid level was present in 38 patients (25.3%). Based on the results of echocardiographic examination, left ventricular hypertrophy was present in 78 patients (52%), 25 of them (32 %) had hyperuricemia. The mean of serum uric acid level, means of age, systolic blood pressure, diastolic blood pressure and lipid profile significantly higher in group I patients compared to those in group II patients. Regarding echocardiographic parameters, There were significantly higher in hyperuricemic patients compared to patients without hyperuricemia the means of interventricular septal thickness, left atrium and left ventricular mass.

Influences on antimicrobial prescribing behaviour of veterinary practitioners in cattle practice in Ireland

Guidelines on prudent antimicrobial use in veterinary medicine have been developed to reduce inappropriate prescribing of antimicrobials. Such guidelines focus mainly on the clinical and pharmacological indications for prescribing. A questionnaire study of veterinary surgeons engaged in cattle practice was completed to determine if non-clinical issues influence the decision to prescribe antimicrobials, and to assess if pharmacological and non-pharmacological issues influence the choice of antimicrobial prescribed. Non-clinical issues, including issues related to professional stress, influenced the prescribing decision of the majority of respondents. However, the nature of the veterinarian–client relationship did not influence the prescribing behaviour of the majority of respondents. Pharmacological and non-pharmacological issues influenced the choice of antimicrobial prescribed. The veterinary surgeon's prior experience of a drug was considered ‘often’ or ‘always’ by 95.7 per cent of respondents when making this decision. The findings of this study have implications for the recognition and management of stress within the profession, and for the development of intervention strategies to reduce inappropriate antimicrobial prescribing.
Automatic Extraction of Lexical Patterns from Corpora

We present our first attempt to extract lexical patterns using corpus statistics. A pattern is a structure that combines syntactic and semantic features and is linked to a conventional meaning of a word. This means, for example, that the verb to die does not have intrinsic meanings, but potential meanings which are activated by the context: in ‘His mother died when he was five’, the meaning of the verb differs from ‘His mother is dying to meet you’, due to collocational restrictions and syntactic differences. With the automatic analysis of thousands of concordances per verb, we can make a first approach to the problem of detecting these structures in corpora, a very time-consuming task for lexicographers. The average precision is around 50%. The next step to increase precision is adding a dependency parser to the system and make adjustments to the automatic taxonomy we have created for semantic labeling.
Logging damages on residual trees during ground based skidding system in the Caspian forests of Iran

In the Iran Caspian forests, logging operation is generally performed by using ground based skidding system. Residual trees are damaged by logging operations in these stands. In this study, after finishing the logging operation in the study area (32ha), the residual tree damages were examined by considering variable factors including logging stages, tree species, location, size and intensity of damages. Systematic sampling method with 100×100m distance and 30 round-shaped sample plots (1000m) were used for collection of data. Results showed that approximately 12.1% of the residual trees were damaged, 1.2% destroyed and 32% of damages are caused by felling stage and 68% by skidding stage. From all damaged trees, 62% belonged to beech, 15% to hornbeam and 10% to alder. Damages on the tree boles are respectively, 11% on stump level, 51% on first 1m and 38% on upper first 1m. Damage sizes very depending on the logging stages. About 54% of the damages intensity observed bark squeezed and 46% wood damaged. Appropriate slvicultural prescriptions and harvesting technologies can reduce wounding to acceptable levels. KeywordsLogging damage, selection cutting, mixed stands, felling, skidding.
RESPONSE OF COTTON GENOTYPES TO BORON UNDER B-DEFICIENT AND B-ADEQUATE CONDITIONS

Balanced boron (B) application is well-known to enhance the cotton production; however, the narrow range between Bdeficiency and toxicity levels makes it difficult to manage. Cotton genotypes extensively differ in their response to B requirements. The adequate dose of B for one genotype may be insufficient or even toxic to other genotype. The effects of boron (B) on seed cotton yield and its various yield associated traits were studied on 10 cotton genotypes of Pakistan. The pot studies were undertaken to categorize cotton genotypes using B-deficient (control) and B-adequate (2.0 kg B ha) levels arranged in CRD with four repeats. The results indicated that the seed cotton yield, yield attributes and B-uptake of genotypes were comparatively decreased in B-deficient stressed treatment. Genotype NIA-Ufaq exhibited wide range of adaptation and ranked as “efficient-responsive”, as it produced higher seed cotton yield under both B-regimes. SAU-2 and CIM-506 were “highly-efficient” and remaining all genotypes were “medium-efficient”. Genotype Sindh-1 produced low seed cotton yield under B deficient condition and ranked as “low-efficient”. B-efficient cotton genotypes can be grown in B deficient soils without B application.
Using Open Data to Analyze Urban Mobility from Social Networks

The need to use online technologies that favor the understanting of city dynamics has grown, mainly due to the ease in obtaining the necessary data, which, in most cases, are gathered with no cost from social networks services. With such facility, the acquisition of georeferenced data has become easier, favoring the interest and feasibility in studying human mobility patterns, bringing new challenges for knowledge discovery in GIScience. This favorable scenario also encourages governments to make their data available for public access, increasing the possibilities for data scientist to analyze such data. This article presents an approach to extracting mobility metrics from Twitter messages and to analyzing their correlation with social, economic and demographic open data. The proposed model was evaluated using a dataset of georeferenced Twitter messages and a set of social indicators, both related to Greater London. The results revealed that social indicators related to employment conditions present higher correlation with the mobility metrics than any other social indicators investigated, suggesting that these social variables may be more relevant for studying mobility behaviors.
ROLE OF FUNCTIONAL GROUPS ON ADSORPTION AND MICROWAVE REGENERATION OF ACTIVATED CARBON FIBER CLOTH

Activated Carbon Fiber Cloth (ACFC) is typically regenerated using resistive heating or steam. There is limited information about the regeneration of ACFC using microwave heating, possibly due to the lack of information about its dielectric properties. This research characterizes the impact of functional groups on the adsorption and regeneration properties of virgin, oxidized, and hydrogen (H2)-treated ACFC. Four grades of ACFC were treated with a concentrated acid mixture or with H2 at 950C. Nitrogen (N2) and water vapor (H2O) adsorption isotherms were obtained to determine the surface areas, distribution of pore sizes and volumes, and adsorption capacities of the virgin and chemically modified ACFCs. X-ray Photoelectron Spectroscopy (XPS) was completed to determine the elemental composition of the samples. The regeneration properties of the resulting ACFC samples were evaluated based on the measurement of their microwave attenuation constants and resistivity. The acid-treated samples contained more oxygen and demonstrated less microwave attenuation and higher resistivity than the virgin samples. In contrast, the H2-treated samples contained less oxygen and demonstrated more microwave attenuation and lower resistivity than the virgin samples. The influence of the chemical treatment on the structure and adsorption of H2O and N2 is also discussed based on the material characterization tests.
Pavement Crack Mosaicking Based on Crack Detection Quality

– A vehicle-mounted video camera, which is one of low-cost off-the-shelf devices, can be used economically for pavement crack monitoring. The pavement frames obtained by the video camera can be merged to form a mosaic image, from which road distress information can be extracted. However, quality of crack detection in the frames is different from one another. The different level of crack detection quality should be considered for accurate construction of crack mosaic. This paper proposes a new pavement crack mosaicking method based on quality of crack detection in each frame. A convolutional neural network is suggested as a way to evaluate the quality of crack detection in the video frames. The proposed method showed a promising mosaicking performance compared to other existing methods.
