Numerical computation of aerodynamic noise of two tandem circular cylinders and flapping wing motion based on immersed boundary method

With the continuous development of theories, numerical computations and computational conditions, computational aero-acoustics presents huge advantages when they are used to solve the aerodynamic noise. Under low Mach number, objects with complex geometric profiles were selected as the research objects to research their aerodynamic noises at stationary and motion conditions by means of hybrid flow and sound separation algorithm for aerodynamic noise based on immersed boundary method (IBM). Firstly, the incompressible flow field was solved based on immersed boundary method, in order to obtain the flow field parameters as the input values, and solve the linearized acoustic perturbation compressible equation under non-uniform Cartesian meshes. As a result, the generation and diffusion of acoustic waves can be simulated. The circumferential flow field of two tandem circular cylinders was firstly completed and compared with the published test results to verify its reliability of the method proposed in this paper. And at different observation points, the noise distribution characteristics of two tandem circular cylinders were studied, showing that the noise in the vertical plane was distributed symmetrically and its noise intensity was greater than that in the horizontal plane. Moreover, the effect of different cylindrical diameters on radiation noise distribution was also studied, showing that the larger the cylindrical diameter was, the radiation noise close to the cylinder was smaller. Sound radiation problems of flapping wing motion were further studied by IBM, and this model was featured with obvious directivity in terms of its acoustic radiation, similar to the dipole sound source, and obvious periodicity regarding its acoustic pressure distribution. With good generality and practicability, this method can be also used for solving aerodynamic noise problems of other machines.
Reconceptualizing Participation for Sustainable Rural Development: Towards a Negotiation Approach

In many popular intervention methodologies aimed at stimulating sustainable rural development (in the widest possible sense) the idea of ‘participation’ is a leading principle. This article will demonstrate that the process in which actors are supposed to participate is often thought of as being a process of planning, decision-making and/or social learning. It will be argued that such an operationalization of development processes is based on inconsistent theoretical assumptions, and can easily lead to unproductive development interventions due to an inability to handle conflicts. As an alternative it is proposed to use negotiation theory as a basis for organizing participatory development efforts. The implications of such a shift in thinking about participation are far-reaching: it requires new modes of analysis, and different roles, tasks and skills for facilitators of participatory processes.

Primary School Student Motivational Intervention Program

This paper presented the concept for a motivational intervention program that would help motivate primary school students. The reasons behind children’s dislike for school are discussed in addition to the different types of motivation, psychological needs, and instrumentality beliefs. This motivational intervention program would be able to encourage students to be more interested and motivated within school intrinsically through a lengthy process. Yet, teachers must participate responsibly and sensitively as well as utilize the recommended methods and activities in order for the program to succeed. However, the potential benefits would be worthwhile and result in a positive outcome for primary school students. Further research and discussion would be required in order to see if this motivational intervention program would truly benefit primary school students in regards to motivation within primary school.
Do the Customers Matter in Mergers and Acquisitions

Purpose: The purpose of this study is to examine the relationship between post merger financial performance and customer reactions on M&As, as well as how the issues of strategic relationships, integration, marketing, and human resources influence these customer reactions. Method: One of the main reasons why M&A research lacks so much of customer reactions is that the methodological mainstream of M&A research in finance, economics, and strategy areas consist of quantitative surveys based on existing stock market and accounting data, which do not include more detailed customer, employee, and process data. The chosen methodology for this research is the case survey methodology which is a “quantitative analysis of patterns across case studies” (Larsson, 1993, p.1). The study contained of 70 M&A case studies, with corss-sectional data that was examined through regression analysis. Theoretical framework: The study was based upon the integrative M&A framework from Larsson and Finkelstein (1999) which examines M&A performance through a holistic view. The customer and marketing dimensions of this study was mainly based upon Oberg’s (2008) studies about customers’ role in M&As. Conclusion: The main finding of this study is the clear and very positive relationship between M&A performance and customer reactions, measured mainly by financial performance but also through synergy realization. Even though this relationship should be obvious and selfevident, the role of the customer in the M&A literature has been poorly examined (Oberg, 2008). This study gives new perspective that the customer reaction matters in the specific M&A situation, compared to previous (Hallowel, 1996) findings that customer satisfaction determine profitability in general. Hence, our findings support the idea that the role of the customer in an M&A is important and should be accounted for when examining determinants and reasons for M&A performance.
Influence of fermented fish meal supplementation on growth performance, blood metabolites, and fecal microflora of weaning pigs

ABSTRACT This study was conducted to estimate the effect of dietary supplementation with fermented fish meal on growth performance, blood metabolites, and fecal microflora in weaning pigs. A total of 180 weaned pigs ((Landrace ×Yorkshire) × Duroc; with average body weight of 6.0 kg) were randomly distributed among three dietary treatments (0, 0.2, and 0.5% fermented fish meal) in three replicate pens (20 heads per pen) in a completely randomized trial over three weeks. Addition of fermented fish meal to [. ]
The Intra-Americas Springtime Sea Surface Temperature Anomaly Dipole as Fingerprint of Remote Influences

Abstract The influence of teleconnections on the Intra-Americas Sea (IAS; Gulf of Mexico and Caribbean Sea) has been mostly analyzed from the perspective of El Nino–Southern Oscillation (ENSO) on the Caribbean Sea (the latter being an extension of the tropical North Atlantic). This emphasis has overlooked both 1) the influence of other teleconnections on the IAS and 2) which teleconnections affect the Gulf of Mexico climate variability. In this study the different fingerprints that major teleconnection patterns have on the IAS during boreal spring are analyzed. Indices of teleconnection patterns are regressed and correlated to observations of oceanic temperature and atmospheric data from reanalyses and observational datasets. It is found that the Pacific teleconnection patterns that influence the IAS SSTs do so by affecting the Gulf of Mexico in an opposite manner to the Caribbean Sea. These analyzed Pacific climate patterns are the Pacific–North American (PNA) teleconnection, the Pacific decadal oscillat.
Nonlinear Models of the Bump Cepheid HV 905 and the Distance Modulus to the Large Magellanic Cloud

Nonlinear pulsation models have been used to simulate the light curve of the LMC bump Cepheid HV 905. In order to reproduce the light curve accurately, tight constraints on the input parameters M, L, and Teff are required. The results, combined with accurate existing V and I photometry, yield an LMC distance modulus of 18.51 ± 0.05, and they show that the luminosity of HV 905 is much higher than expected from the mass-luminosity relation of stellar evolution theory. If we assume that the pulsation models are accurate, this suggests that there is a larger amount of convective core overshoot during the main-sequence evolution of stars with M ~ 5 M☉ than is usually assumed.
Molecular marker analysis of ‘Shatangju’ and ‘Wuzishatangju’ mandarin ( Citrus reticulata Blanco )

‘Wuzishatangju’( Citrus reticulata Blanco ) is an excellent cultivar derived from a bud sport of a seedy ‘Shatangju’ cultivar found in Guangdong Province in the 1980s. In this study, six molecular markers including random amplified polymorphic DNA (RAPD), inter-simple sequence repeat (ISSR), simple sequence repeat (SSR), sequence-related amplified polymorphism (SRAP), inter-retrotransposn amplified polymorphism (IRAP) and retrotransposon-microsatellite amplified polymorphism (REMAP) were used to study the genetic variations between ‘Shatangju’ and ‘Wuzishatangju’. 1196 RAPD, seven SSR, 28 IRAP and 56 REMAP primers were used to detect the genetic variations between ‘Shatangju’ and ‘Wuzishatangju’. However, no difference was observed between the two cultivars. These results indicate that there was a very close genetic relationship between ‘Shatangju’ and ‘Wuzishatangju’ and RAPD, SSR, IRAP and REMAP markers could not distinguish them. Two and 21 specific bands were obtained using 100 ISSR and 153 SRAP primers, respectively. The present research could be a valuable tool for identification of Citrus bud sport clones, which laid the foundations for the further study of the mechanisms of Citrus bud sports. Key words : Citrus reticulata Blanco, random amplified polymorphic DNA (RAPD), inter-simple sequence repeat (ISSR), simple sequence repeat (SSR), sequence-related amplified polymorphism (SRAP), inter-retrotransposon amplified polymorphism (IRAP), retrotransposon-microsatellite amplified polymorphism (REMAP), identification.
Characterization and antibiotic susceptibility pattern of Bacillus cereus isolates from fried soyabean cake in Zaria, Nigeria

A total of one hundred and fifty fried soyabean cake samples were collected from different vendors in various parts of Zaria, Kaduna state and were assessed for the presence of Bacillus cereus . 84 out of the total 150 were positive for B. cereus given a prevalence of 56%. All the samples tested contained more than 10 5 cfu/g of the bacterium with a mean count value of 7.8±7.1 log cfu/g. Isolates were tested for enterotoxin production using the BCET-RPLA kit and 90% of the isolates were found to possess the L 2 fraction of the HBL components. All enterotoxic B. cereus isolates were found to be susceptible to Amikacin (30µg), Ciprofloxacin (5µg), Gentamicin (10µg) and Tetracycline (30µg). 100% resistance was observed against Ampicillin (10µg) and Oxacillin (1µg). The percentage resistance to Bacitracin (10µg), Chloramphenicol (30µg), Erythromycin (15µg) and Vancomycin (30µg) of the enterotoxic isolates are 56%, 33%, 39% and 44% respectively.
Untreated Natural Graphite as a Graphene Source for High-Performance Li-Ion Batteries

Graphene nanosheets (GNS) are synthesized from untreated natural graphite (NG) for use as electroactive materials in Li-ion batteries (LIBs), which avoids the pollution-generating steps of purifying graphite. Through a modified Hummer method and subsequent thermal exfoliation, graphitic oxide and graphene were synthesized and characterized structurally, morphologically and chemically. Untreated natural graphite samples contain 45–50% carbon by weight; the rest is composed of different elements such as aluminium, calcium, iron, silicon and oxygen, which are present as calcium carbonate and silicates of aluminium and iron. Our results confirm that in the GO and GNS synthesized, calcium is removed due to oxidation, though other impurities are maintained because they are not affected by the synthesis. Despite the remaining mineral phases, the energy storage capacity of GNS electrodes is very promising. In addition, an electrochemical comparison between GNS and NG demonstrated that the specific capacity in GNS is higher during the whole cycling process, 770 mA·g−1 at 100th cycle, which is twice that of graphite.
Soft Clay Stabilization with Geosynthetic Vertical Drains beneath Road and Railway Embankments: A Critical Review of Analytical Solutions and Numerical Analysis

In the wide array of existing ground improvement schemes, the use of vertical drains with vacuum preloading is considered as the most effective and economical method for improving soft clays (normally consolidated to lightly over-consolidated) prior to construction of infrastructure. Vertical drains installed to significant depths promote radial flow inducing consolidation rapidly enhancing the shear strength of the compressed ground. In this paper, the analytical solutions based on lateral soil permeability (parabolic variation) are discussed considering the variation of vacuum pressure with depth along the prefabricated vertical drains (PVD). Using the Cavity Expansion Theory (CET), the smear zone caused by the installation of PVD by steal mandrel was predicted and compared with laboratory measurements obtained from large-scale radial consolidation tests. The effects of drain unsaturation and vacuum pressure along the drain length are also discussed. The numerical analyses incorporating equivalent plane strain solutions were performed to predict the soil responses based on two selected case histories in Thailand. The research findings provided insight as to which of the above aspects needed to be simulated accurately in numerical modelling. The application of cyclic loading on PVD stabilized ground was also examined using a finite element approach under railway embankment. It is demonstrated that short drains less than 8 m installed beneath tracks are still useful for effective dissipation of cyclic
Capital Structure and Firm Performance of Listed Non-Financial Companies in Bangladesh

This study investigates the firm performance on capital structure for the listed non-financial companies in Dhaka Stock Exchange (DSE) for the enter period of 2008-2011 under judgment sampling method. Specific objective of this research is to examine the relationship between the attribute of capital structure and the firm performance. Multiple regression models are used to estimate the influence of capital structure on firm performance. Capital structure is measured by the Debt Ratio, Debt to Equity Ratio, Current Debt Ratio, Proprietary of Equity Ratio and Current assets proprietors' funds Ratio and firm performance as measured by return on assets (ROA) and return on sales (ROS). The results obtained from regression models show that Debt Ratio, Debt Equity Ratio and Proprietary of Equity Ratio are negatively and significant relationship with return on asset (ROA) and return on sales (ROS). Beside the control variable total asset is positively and significant relationship with return on asset (ROA) and return on sales (ROS).
Relativistic magnetohydrodynamical simulations of the resonant corrugation of a fast shock front

The generation of turbulence at magnetized shocks and its subsequent interaction with the latter is a key question of plasma-and high-energy astrophysics. This paper presents two-dimensional magnetohydrodynamic simulations of a fast shock front interacting with incoming upstream perturbations, described as harmonic entropy or fast magnetosonic waves, both in the relativistic and the sub-relativistic regimes. We discuss how the disturbances are transmitted into downstream turbulence and we compare the observed response for small amplitude waves to a recent linear calculation. In particular, we demonstrate the existence of a resonant response of the corrugation amplitude when the group velocity of the outgoing downstream fast mode matches the velocity of the shock front. We also present simulations of large amplitude waves to probe the non-linear regime.
Pollen source and resource limitation to fruit production in the rare species Eremosparton songoricum (Fabaceae)

Eremosparton songoricum (Litv.) Vass. is a rare, central Asian desert species which shows lower fruit set and seed set (l 16%) than most hermaphroditic species. We hypothesized that fruit production was limited by pollen and resources. To evaluate potential fruit abortion due to pollen limitation, supplemental hand-pollination was undertaken, the mating system was investigated and the foraging behavior of pollinators was recorded. To investigate possibile resource limitation, flowers and young pods were artificially removed and fertilization were manipulated. The results showed that under natural pollination, the number of pollen deposited on the stigma greatly exceed the number of ovules per ovary. Mating system experiments showed that the species is self-compatible, but depended on pollinators to set seeds. Supplemental outcross pollination increased fruit set significantly. The most frequent effective pollinator Megachile terminate Morawitz, was observed pollinating many flowers of the same individual plant (74.5 +/- 1.3%). These results suggested that fruit production is affected by insufficient outcross pollen rather than by pollen quantity. Removal of 2/3 of the flowers and young pods led to significantly higher fruit set, as did addition of fertilizers (N-P-K: 0.025-0.05-0.013 g, N-P-K: 0.05-0.1-0.025 g) showing that reducing resource acceptors and increasing inorganic resources both helps to improve fruit set. We therefore conclude that reproductive success of E. songoricum is limited by both outcross pollen and available nutrients.
Comparison Evaluations of VRF and RTU Systems Performance on Flexible Research Platform

The energy performance of a variable refrigerant flow (VRF) system was evaluated using an occupancy-emulated research building in the southeastern region of the United States. Full- and part-load performance of the VRF system in heating and cooling seasons was compared with a conventional rooftop unit (RTU) variable-air-volume system with electric resistance heating. During both the heating and cooling seasons, full- and part-load conditions (i.e., 100%, 75%, and 50% thermal loads) were maintained alternately for 2 to 3 days each, and the energy use, thermal conditions, and coefficient of performance (COP) for the RTU and VRF system were measured. During the cooling season, the VRF system had an average COP of 4.2, 3.9, and 3.7 compared with 3.1, 3.0, and 2.5 for the RTU system under 100%, 75%, and 50% load conditions and resulted in estimated energy savings of 30%, 37%, and 47%, respectively. During the heating season, the VRF system had an average COP ranging from 1.2 to 2.0, substantially higher than the COPs of the RTU system, and resulted in estimated energy savings of 51%, 47%, and 27% under the three load conditions, respectively.
Spatial distribution of the Asian citrus psyllid, Diaphorina citri Kuwayama (Homoptera: Psyllidae) on citrus and orange jasmine

The analysis of spatial distribution of the psyllid Diaphorina citri (Homoptera: Psyllidae) on citrus and orange jasmine analyzed using various mathematical indices of dispersion and regression models showed an aggregated distribution. Taylor's power law and Iwao's regression model fitted very well to all data sets, while the regression of k = c + dm (k = m 2 /(s 2 - m)) was an inadequate model for the aggregation of the citrus psyllid since k was unstable and dependent upon the density of the insect. In general, Taylor's power law fitted the data better, yielding higher values of R 2 than the Iwao's model for all cases, whether citrus only, orange jasmine only or pooled. The population of D. citri on the tree quadrants, i.e. north, west, south and east, did not differ significantly. However, distribution between the upper and lower half of the canopy was significantly different where the upper canopy harbored more psyllids than the lower half.
The Proangiogenic Potential of Mesenchymal Stem Cells and Their Therapeutic Applications

Mesenchymal stem cells (MSCs) can be isolated from many tissue types and following in vitro culture expansion, large numbers of patient-specific or allogenic cells can be produced for clinical applications. MSCs exhibit anti-inflammatory and immunomodulatory properties and are identified as lacking major histocompatibility complex (MHC) class II molecules. Cellular-based approaches using MSCs to enhance new blood vessel formation have shown promise in preclinical models and preliminary clinical trials. Transplantation of MSCs in vivo has significantly enhanced the formation of new blood vessels and promoted the healing of chronic wounds. The proangiogenic potential of MSCs can be further enhanced through gene delivery such as vascular endothelial growth factor (VEGF) or endothelial nitric oxide synthase (eNOS) providing long-term therapeutic expression. In this chapter, we review recent advances on the isolation and characterization of MSCs and in vivo applications for promoting angiogenesis. Enhancement of angiogenesis is also required for improved healing in myocardial infarction and cerebral ischemia, and the use of MSCs in these areas will also be reviewed. Furthermore, the combination of MSCs with biomaterials has greatly improved their survival and potency with improved vascularization of tissue-engineered constructs and integration within the host. In summary, this chapter provides an overview of both the basic science supporting the proangiogenic properties of MSCs and their translational use.
