Is a Flat Inlet Profile Sufficient for WSS Estimation in the Aortic Arch

Atherosclerosis is one of the main reasons for cardivascular disease which cause many deaths every year especially in the Western world. The development of atherosclerosis is strongly believed to be influenced by hemodynamic forces in the arteries e.g. wall shear stress (WSS). Estimations of WSS are therefore very important. By combining magnetic resonance imaging (MRI), image processing and computational fluid dynamic (CFD) simulations, it is possible to estimate subject specific WSS in the human arteries. The framework for performing such work includes i.e. using inlet boundary conditions which, however, will influence the final result i.e. the WSS distribution. This paper aims to investigate the influence of the inflow boundary condition in the human aorta with comparing two settings for the inflow: 1) subject specific inlet profile measured with MRI and 2) uniform profile with the subject specific mass flow rate. The analysis of WSS will be performed both on spatial location along the artery as well as on the temporal location in the cardiac cycle. Subject specific data have been used for geometry, inflow velocity profile and blood viscosity. The recommendation due to our findings from nine healthy subjects, is that a measured subject specific inlet boundary condition must be used in order to get a subject specific WSS distribution; the difference in WSS is 8-34% compared to using a mass-flow correct uniform profile. Temporal variations were clearly seen in the WSS differences due to the different inflow velocity profiles used. The lowest influence of the inlet boundary condition was found at peak velocity in the cardiac cycle. The aortic geometry does not form the flow in such extent (compared to the influence by inlet boundary condition) to obtain a more correct WSS distribution further away from the inlet at the systolic parts of the cardiac cycle. The shape of the vessel has only a significant influence at low velocities i.e. the diastolic phase of the cardiac cycle.
Financial Crisis, Structure and Reform

In this study, we examine the relationship between the structure of financial systems and financial crises. Using cross-country data on financial structures and crises, we find that there is a significant short-term reversal in development of the banking sector and the stock market during both bank crises and market crashes, with the corporate bond market moving in the same direction as bank credit. However, the results are significant for countries with market-based financial systems but not for countries with bank-based financial systems. Emerging markets have mainly bank-based financial systems, which may explain why these markets require more time to recover from economic downturns after a financial crisis. Therefore, we argue that governments should emphasize a balanced financial system structure as it helps countries to recover from financial crises more quickly compared with countries that lack such balanced structures.
Experimental Investigation of Chatter Dynamics in Thin-walled Tubular Parts Turning

Chatter prediction is nowadays frequently carried out for machining operations involving deformable parts or tools. These analyses are commonly based on the uncoupled elements of the system: frequency response of the deformable parts under non-rotating conditions and cutting law. The present investigation puts forward the dynamics of a thin-walled tubular part during straight axial turning undergoing chatter instability. Studied system’s peculiarities include quasi-static nominal cutting conditions and twin flexural modes featuring strong variation of modal characteristics along the pass. The measurement records, based mainly on fixed-frame non-contact eddy-current displacement probes, are performed during the machining operation. Additional hammer modal analysis tests are also carried out. As can be observed from time and spectral analysis of the records, the system's response features several characteristic phenomena as, for example, twin mode separation. The influence of different factors, such as the additional stiffness due to the tool presence, gyroscopic effects and the fixed sensors measurement on rotating part is investigated.
Rapid lipid enrichment in ω3 fatty acids : Cause-to-effect relationships

The bolus intravenous administration of a novel medium-chain triglyceride:fish oil emulsion to second generation rats depleted in long-chain polyunsaturated omega3 fatty acids was recently found to enrich within 60 min the content of both plasma and liver lipids in such omega3 fatty acids, this coinciding with correction of the perturbation in liver triglyceride fatty acid content and profile otherwise prevailing in these rats. The present report draws attention to cause-to-effect relationships between changes in liver phospholipid and triglyceride fatty acid content and/or pattern operative under these experimental conditions.
Mediation Effect of Performance Appraisal Management on the Work Environment -- Job Satisfaction Relationship among Support Staff in a University in Uganda.

The suitability of work environment is an important antecedent of effective performance appraisal management process and job satisfaction among employees within an organization. This study examined the mediation effect of performance appraisal management on the relationship between work environment and job satisfaction among support staff at a public university in Uganda. The study employed crosssectional survey design. A structured, closed ended questionnaire containing mainly 5–point Likert type items was administered to a census of 207 support staff of the university; 172 (83.1%) responses were complete and used in data analysis. Findings revealed that the support staff ratings of suitability of work environment, effectiveness of performance appraisal management, and job satisfaction at the university were at moderate levels. In addition there was a partial mediation effect of performance appraisal management on the work environment – job satisfaction link at the university. Policy implications include deliberate effort on the part of management to provide suitable working conditions and enhance effective performance appraisal management so as to increase job satisfaction among the support staff.
Farmers’ perception of the effects of soil and water conservation structures on crop production: The case of Bokole watershed, Southern Ethiopia

Level soil bunds (LSB) and stone bunds (SB) have been widely implemented in Bokole watershed with World Food Programme (WFP) support since 2000-2001. However, the performance of structures against the target has not been studied. This study assessed farmers’ opinion on the effect of soil and water conservation (SWC) structures, particularly level soil bunds and stone bunds, in improving agricultural crop production. A household survey was carried out by stratified random sampling. Twenty-seven percent of the farmers who adopted SWC structure (29 households from the upper watershed and 62 households from the lower watershed) were randomly selected and interviewed. Three group discussions were also conducted. Based on their own indicators, a high proportion of those interviewed (79.3% in the upper and 87.1% in the lower watershed) had a positive opinion about LSB and SB on their cropland, in relation to its role in improving soil fertility and crop production. Ninety-three percent of interviewed farmers in both the upper watershed and the lower watershed perceived a change in crop yield within two years after implementation of structures. There is a need for awareness creation and for monitoring the correct management of existing soil and water conservation structures, to ensure that they function as intended, and to improve their efficiency. This can reduce the problem of a ‘decrease’ or ‘fluctuation’ in crop yield. Key words : Crop yield, non-terraced, soil bunds, stone bund, water erosion.
TECHNIQUES TO IMPROVE GROWTH, MORPHOGENESIS AND SECONDARY METABOLISM RESPONSES FROM LAMIACEAE SPECIES IN VITRO

Abstract Cultural procedures to improve growth (fresh weight) and morphogenic (leaves, shoots and roots) development in the mint family (Lamiaceae) species (e.g. basil, catnip, oregano and spearmint) in vitro are presented. Novel plant tissue culture systems were employed to increase biomass and shooting. A survey study with several species is presented testing a wide range of CO2 levels. Employment of ultrahigh levels of CO2 (i.e. ≥3,000 μL CO2 L) promoted greater growth and morphogenesis in most mint species compared to that obtained employing ambient air (350 μL CO2 L). Employment of a sterile hydroponics system, i.e. an automated plant culture system (APCS), greatly enhanced spearmint biomass and shooting over that obtained employing an agar medium. Analysis of essential oil composition in spearmint cultures grown in various culture systems reveals that high secondary metabolite production is often associated with high growth and morphogenesis responses.
Effect of an educational intervention on midwifery students' knowledge and preparedness about oral health care in pregnant mothers

Background and Aims : As midwives are in frequent contact with pregnant mothers, they may play a key role in their oral health care (OHC). In this study, we aimed to evaluate the effect of an educational program on Tehran University of Medical Sciences midwifery students’ knowledge and preparedness on OHC in pregnant mothers. Materials and Methods: The midwifery third year students of central campus (n=29) were randomly selected as intervention group and their counterparts in Hemmat campus (n=33) as control. Students in both groups were asked to fill in a questionnaire included 8 demographic question and 18 OHC knowledge and one question on their preparedness to implement OHC. Then the educational intervention was implemented using lecture, demonstration of the correct methods of brushing and flossing on the models and role play method. The follow-up questionnaire was delivered 3 months later. Data were analyzed using Mann-Whitney test, T-test, Chi-Square test, ANOVA and Regression by SPSS software. Results: The mean OHC in pregnancy knowledge score in intervention and control group were 26.7 and 24.8 at baseline which were changed into 48.5 and 29.1, respectively (P<0.001). Among the students 52.6% in the intervention group and 36.4% in the control group reported very high preparedness to implement OHC in pregnancy. These figures were 68.2% and 41.7% in the post-test. Conclusion: The promising findings of this educational intervention comprising of both student and teacher-centered methods speak for possibility of improving these students knowledge and preparedness and implies on the necessity to incorporate the related course in midwifery education.
Modeling of Spray Combustion with a Steady Laminar Flamelet Model in an Aeroengine Combustion Chamber Based on OpenFOAM

The development of high-performance aeroengine combustion chambers strongly depends on the accuracy and reliability of efficient numerical models. In the present work, a reacting solver with a steady laminar flamelet model and spray model has been developed in OpenFOAM and the solver details are presented. The solver is firstly validated by Sandia/ETH-Zurich flames. Furthermore, it is used to simulate nonpremixed kerosene/air spray combustion in an aeroengine combustion chamber with the RANS method. A comparison with available experimental data shows good agreement and validates the capability of the new developed solver in OpenFOAM.

Genetic diversity of Tribolium castaneum (Herbst) population in storage infrastructures and agro ecological zones in Senegal.

The stocks of millet are attacked by the beetle among them T. castaneum. This devastator attacks the grain and causes important losses as for as the stocks of ground millet in the sahel. The aim of this study is to evaluate genetic diversity of T. castaneum population meet in the stocking infrastructures and the different agroecological areas with the intention to identify the different haplotypes that walk around. Portions of the cytochrome b and 28S ribosomal genes of T. castaneum were sequenced, using samples from that represent storage infrastructures and agroecological areas in Senegal. The results reveal a strong haplotype diversity in the stores of Sandiara (0.889±0.127) and Diaroume (0.556±0.165). The population of T. castaneum meet in the stores who supply themselves locally as that of Djilas show a weak haplotypique and nucleotidic diversity. The cereals marketing at the markets such as the Sandiara one would be at the origine of the wealth haplotypic observed in the store taken as an exemple in this locality. The pourcentage (0.16%) of molecular variance analysis (AMOVA) shows that there is not a significant genetic differentiation between agroecological areas. The test of Mantel shows that there is no correlation between geographical distance and genetic differenciation.
Metal oxide semiconductor structure using oxygen-terminated diamond

Metal-oxide-semiconductor structures with aluminum oxide as insulator and p-type (100) mono-crystalline diamond as semiconductor have been fabricated and investigated by capacitance versus voltage and current versus voltage measurements. The aluminum oxide dielectric was deposited using low temperature atomic layer deposition on an oxygenated diamond surface. The capacitance voltage measurements demonstrate that accumulation, depletion, and deep depletion regimes can be controlled by the bias voltage, opening the route for diamond metal-oxide-semiconductor field effect transistor. A band diagram is proposed and discussed.
Partnering to Facilitate Smallholder Inclusion in Value Chains

In light of the importance of agricultural activities for the livelihoods of millions of people in rural areas, poverty-alleviating growth depends to a high degree on access to lucrative consumer markets. However, smallholder farmers in developing countries face various institutional constraints that hinder them taking advantage of market opportunities. A lack of information on prices and technologies, lacking connections to market actors, underdeveloped financial markets and scale diseconomies make it difficult for smallholders to reach out to international or new domestic markets. Thus, new institutional arrangements are needed to fill the gap in between current local practices/institutions and the institutions required for participation in value chains. As an example of a new institutional arrangement, partnerships between businesses, NGOs, farmers and public agencies have emerged to create new and better outlets for smallholders’ products, achieve positive socio-economic and environmental outcomes for farmers, and serve the purpose of pro-poor growth. By building on the expertise of each member, partnerships are an example of collective action based on differences in comparative advantage and agency specialization to create collaborative advantage. Actors have different roles that can complement each other and address the institutional constraints faced by smallholders, thereby fulfilling development goals and private business interests at the same time. For this reason, partnerships have made a remarkable breakthrough in the international development discourse.
erry-cluster thinning to prevent bunch compactness of ‘ BRS Vitoria ’ , new black seedless grape ergio

The objective of this study was to evaluate techniques, such as flower-cluster and berry-cluster thinning at different times, to prevent bunch compactness of ‘BRS Vitoria’, a new black seedless grape. The experiment was conducted during two consecutive seasons (2013 and 2014) in a commercial vineyard located in Marialva, PR, Brazil. The grapevines were trained in an overhead trellis system, spaced at 2.5 × 5.0 m. The experimental design used was randomized blocks with four replications and six treatments: control (no thinning); flower-cluster thinning or brushing prior to anthesis; and berry-cluster thinning at different times, when berries were 3–6, 7–10, 11–15, or 16–18 mm in diameter. The bunch compactness incidence was evaluated according to the following classification: very loose, medium loose, and very dense bunches. The physicochemical characteristics of bunches and the yield were also evaluated. ine itis spp. Data were submitted to analysis of variance, and means were compared using Tukey’s test at 5%. Berrycluster thinning when ‘BRS Vitoria’ berries are between 7 and 18 mm in diameter is efficient for reducing bunch compactness, as it results in a higher incidence of medium loose and a lower incidence of very dense bunches with optimum yield, while flower-cluster thinning or brushing prior to anthesis should be avoided because it promotes higher incidence of very loose bunches with reduced yield. © 2015 Elsevier B.V.

Optimization of Soxhlet Extraction of Herba Leonuri Using Factorial Design of Experiment

Soxhlet extraction technique is employed for the extraction and separation of chemical constituents in the medicinalplant, Herba Leonuri. The main goal of this analytical study was focused on extracted compounds and extractionconditions themselves. Soxhlet extractions were performed at three extraction time (6h, 9h and 12h) and with twosolvents (n-hexane and methanol). A general full factorial design with two factors (extraction time and types ofextractor solvents) was implemented. The Soxhlet extraction method presented a good yield of components in extract.The study shows that methanol extracted almost double yield than n-hexane. The highest yield obtained with methanolwas 14.18%; while the highest yield obtained by n-hexane was 7.25%. The results also indicated that, for methanolextraction, the mass yield percent extracted increased with increasing length of extraction period (up to 14.18%); forn-hexane extraction, the mass yield percent extracted was not consistent with increasing length of extraction period. Theextracted oil extracted was analyzed by GC-MS. The compounds identified were vitamin E, palmitic acid and syringol.General characteristics of the Herba leonuri oils obtained by different conditions were further compared, showing thatthe composition of the Herba leonuri oil extracted by different conditions is mostly similar, whereas relative concentration of the identified compounds is apparently different. This study can be considered as the first informationon the chemical compound of Herba leonuri.
The Role of Lipid-Lowering Treatment in the Secondary Prevention of Ischemic Stroke

Dyslipidemia is a major modifiable risk factor for ischemic stroke. Treatment with statins reduces the incidence of recurrent ischemic stroke and also reduces coronary events in patients with a history of ischemic stroke. Therefore, statins represent an important component of secondary prevention of ischemic stroke. In patients who do not achieve low-density lipoprotein cholesterol (LDL-C) targets despite treatment with the maximal tolerated dose of a potent statin, ezetimibe should be added to their lipid-lowering treatment and also appears to reduce the risk of cardiovascular events. Selected patients who do not achieve LDL-C targets despite statin/ezetimibe combination are candidates for receiving proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors. Finally, it appears that adding icosapent ethyl might also reduce cardiovascular morbidity in patients who have achieved LDL-C targets but have persistently elevated triglyceride levels.
A REVIEW BASED ON THE RELATIONSHIP AMONG DRYING, CURVE FITTING AND MATHEMATICAL MODELS IN FOOD SYSTEMS

Drying process extends the shelf life stability of foods that preserve the quality and food stability by removal of water. Several drying methods are being used such as microwave, vacuum-microwave, freeze drying, convective air, spray drying, fluidized bed drying and infrared-convective for drying purposes.There is a close relationship between deteriorative reactions and final moisture contents in food materials. The final moisture content affects the storage capabilities and shelf-life of foods and to predict the moisture contents of foods mathematical models are being used at any drying time. The correlation coefficient (R2), the reduced chi-square (x2) and root mean square of error (RMSE %) are used to fit to the models for drying curves. Increase drying temperature,drying air,microwave heating watts result an increase in drying rate and effective moisture diffusivity. Drying with microwave method is effective method for food preservation and rate of drying is higher than traditional drying methods.Microwave or infrared drying enhances drying rate and rapid process that creates a porous,crispy and delicious texture of the food samples.
Title Land Use Regulations , Compliance and Land Markets in Argentina Permalink

Empirical evidence on the impact of stringent land use regulations on the price of land and housing in urban areas is growing, yet most research has been carried out in countries where ordinances are enforced. If enforcement is lax, the ultimate impact of strict rules on land and housing prices is unclear. Lower levels of compliance with rules can result in negative externalities and thereby exert downward pressure on the price of formal land. This paper presents an empirical analysis of the relationship between land use regulations, compliance and land prices in the three major metropolitan areas of Argentina, the country with the most stringent land use and urban development regulations in Latin America, using an original dataset gathered from parceland municipal-level surveys. Results show that municipalities with higher levels of regulation have lower rates of compliance with property laws, and lots selling legally in these municipalities have lower land prices.
