SECTIONAL AERODYNAMIC FORCES AND THEIR LONGITUDINAL CORRELATION ON A VIBRATING 5 : 1 RECTANGULAR CYLINDER

The aerodynamics of simple geometries such as the circle, the square and the rectangle is of interest for both fundamental research and practical applications in many areas of Engineering. In particular, rectangular cylinders have received large attention due to the fact that they offer a broad range of types of aerodynamic and aeroelastic behaviour, depending on the aspect ratio. A wide variety of results of wind tunnel measurements and of CFD analyses are available in the literature. In this paper some features of the aerodynamics of a 5:1 rectangular cylinder are presented, as obtained from wind tunnel pressure measurements, through comparison between the case in which the cylinder is located in a smooth flow and the case in which it is located in a turbulent flow. In addition, in the case of an oncoming smooth flow, the aerodynamics of the cylinder vibrating in a torsional flutter mode is considered, and compared to that of the stationary cylinder. The sectional distribution of the statistics of the pressure coefficients (mean, RMS, skewness and kurtosis) have been analysed, together with Probability Density Functions and the Power Spectra of the pressure fluctuations. Finally, the spanwise correlation of pressure fluctuations is investigated. Some of the modifications brought to the flow around the section by the addition of turbulence or by the motion of the cylinder have been inferred. Francesco Ricciardelli, Antonino M. Marra
3 D NUMERICAL SIMULATION OF BASIN EFFECTS ON THE CHARACTERISTICS OF BASIN-TRANSDUCED RAYLEIGH WAVES

This paper presents the effects of impedance contrast at basin-edge and basin-width on the spectral amplification and complex mode transformation of basin transduced Rayleigh (BTR) waves. BTR-wave, the acronym for basin transduced Rayleigh wave is used in the manuscript. 3D seismic responses of a 2D basin with varying width were computed using a developed 3D fourth-order spatial accurate time-domain finite-difference (FD) algorithm based on parsimonious staggered-grid approximation of 3D viscoelastodynamic wave equations. Analysis of computed seismic responses on the horizontal array across the basin revealed that a complex mode transformation of Rayleigh wave at the basin-edge has caused diffracted body waves, reflected Rayleigh wave and different modes of BTR-waves. Very large amplification of BTR-wave as compared to body waves is obtained for a certain frequency depending on the width of basin. It is concluded that spatial spectral amplification of BTR-wave in basin very much depends on position as well as width of basin. Currently, only body wave amplification in basin is being considered in earthquake resistant designs and seismic microzonation, although surface waves are more damaging as compared to the body waves. Further, the study on amplification of basin-transduced surface waves is very limited. The findings of this paper reveal that basin-edge effects on basin-transduced surface waves deserve a particular attention for the purpose of earthquake resistant designs and seismic microzonation.
Chemical composition and diversity of lactic acid bacteria in guinea grass based

Ensilage is considered that widespread among conserving method of fodder crops. The successes of this process depend on bacteria in lactic acid bacteria (LAB) group as existing in forage crops. The chemical composition and diversity of lactic acid bacteria in silages based on guinea grass was investigated. Result showed that the silages contained 62.55 to 76.47% moisture, 23.53 to 37.45% dry matter (DM) and 6.11 to 15.74% ash. Groundnut silage (T3) showed the lowest crude fiber (CF), neutral detergent fiber (NDF) and acid detergent fiber (ADF) contents. Two hundred and eighty-two isolates of LAB were isolated from five silage formula based on guinea grass supplementation with either lead tree leaves or groundnut. Most of isolates were gram-positive and catalase-negative bacteria. Based on morphological characteristics and PCR-RAPD analysis, the isolates were divided into 21 groups (Guinea Grass Mixed Legume Silage (GMLS) 1 to GMLS21). The phylogenetic relation of the representative strains was analyzed from the data of 16S ribosomal DNA sequencing. Prevalent of LAB found in the silages included Lactobacillus plantarum, Pediococcus acidilactici, Pediococcus pentosaceus, Enterococcus hirae, and Weissella paramesenteroides. L. plantarum was a dominant population and found distribution in all silage formula. This study revealed that the silage samples, including guinea grass, lead tree and groundnut contain mainly of L. plantarum. The information obtained can be used for the anterior design of reasonable inoculants for improvement of silage quality for cattle feed.
The Influence of School Demographics on the Relationship Between Students' Help-Seeking Behavior and Performance and Motivational Measures

Demographic information often proves useful for finding subpopulations in educational data. Unfortunately, it is often not collected in the log files of online learning systems, which serve as one of the primary sources of data for the Educational Data Mining community. Recent work has sought to address this issue by investigating school-level differences in demographics, which can be used to discover trends in data where individual-level variation may be difficult or impossible to acquire. In this study, we use this approach to investigate the effect of demographic patterns on hint usage in an elementary level mathematics system, comparing this use to performance and motivational measures. In doing so, we expand upon the research into help-seeking behaviors, which typically takes a cognitive approach. Our results suggest the need to better understand what social factors are most likely to motivate help-seeking behaviors, particularly since research on their effectiveness has been mixed.
Cigarette smoke effect on total salivary antioxidant capacity, salivary glutathione peroxidase and gamma‐glutamyltransferase activity

Saliva is the first biological fluid that inhaled cigarette smoke (CS) encounters. CS contains several carcinogens known to initiate and promote tumourigenesis and metastasis. One of the aims of this study was to establish if glutathione peroxidase and gamma‐glutamyltranspherase (GGT) could be used as possible markers for evaluating the oral oxidative stress caused by smoking. The effect of CS on free radical generation was investigated using two methods. Using different assays, different antioxidants present in saliva may be evidenced due to the different principles on which they are based.
Microtus ( Tyrrhenicola ) sondaari n . sp . ( Arvicolidae , Rodentia ) from Monte Tuttavista ( Sardinia , Italy ) *

The genus Tyrrhenicola has been instituted by FORSYTH MAJOR in 1905 to describe the insular fossil vole remains coming from Corse and Sardinia discovered by CUVIER in 1823 and is now considered a subgenus of Microtus; though considering it at a subgeneric level, for a purpose of simplicity from now on it will be called just T y r r h e n i c o l a. T y rrhenicola (Arvicolidae, Rodentia, Mammalia) is an endemic fossil vole widespread in Sardinia and Corsica during Middle Pleistocene to Holocene with the only species T y rrhenicola henseli. Though different evolutionary degrees have been recognised between different populations of T. henseli (MEZZABOTTA et al., 1996), the systematic position and the phylogenetic relationships of Tyrrhenicola are still controversial. After the institution of the new genus T y rrhenicola by FORSYTH MAJOR, CHALINE (1972) following the considerations of HINTON (1926) not only suggested that it represented an insular differentiation of Terricola, because of its skull features and the presence of a pitymyan rhombus in the first lower molars, but also that it belongs t o the same subgenus Microtus (Terricola) and proposes an evolution from some Allophaiomys f o r m s like the other Terricola. On the contrary VAN DER ME U L E N (1973) and RABEDER (1981) believe the similarities with Terricola to be only a parallelism and propose an evolution from A l l o phaiomys pliocaenicus, suggesting an immigr ation to Sardinia during Early Pleistocene. Later on BRUNET-LECOMTE & CHALINE (1990) further suggest that Tyrrhenicola henseli may represent an archaic branch of the Mediterranean group of Terricola they suppose to be derived from an evolved form of Allophaiomys, A. chalinei that might have reached Sardinia and Corse during the early Middle Pleistocene. MI N I E R I et al. (1995) recognise several morphotypes in first lower molars and third upper molars of the Late Pleistocene Cava Alabastro (Is Oreris, Sardinia) and suggest an evolution from A. ruffoi from the Italian Late Villafranchian. ME Z Z A B O T T A et al. (1996), on the basis of s o m e morphometric analyses, propose an evolution from the Allophaiomys ruffoi-burgondiae group and an immigration Microtus (Tyrrhenicola) sondaari n. sp. (Arvicolidae, Rodentia) from Monte Tuttavista (Sardinia, Italy)*
Social Capital , Health Related Behavior and Hygienic Practices of the Extreme Poor in Rural Bangladesh

Empirically there is literature, though focusing mainly on the developed countries, to report positive association of social capital and health outcomes. However, the literature studying the association between social capital and health related behavior and hygienic practices in the developing countries, specially among the hardcore poor is largely absent. In this context, this paper studies association between social capital and the health seeking behavior and hygienic practices among 4900 extreme poor households in rural Bangladesh. Instrumental Variable Probit regression is used for the study purpose. The empirical results indicate strong effects of social capital among the extreme poor of the rural Bangladeshi households on the determinant of their health seeking behavior and hygienic practices: use of sanitary toilet, soap after defecation, using iodized salt, sources of cooking water, family planning and knowledge about arsenic in water. The results thus indicate that social cohesion, connection and network can be used by the government and non-government organizations of the country delivering health services to the poor to reap benefit from the existing social capital of the society.
High prevalence of significant histology in asymptomatic chronic hepatitis B patients with genotype C and high serum HBV DNA levels

Summary. Current treatment guidelines suggest that antiviral therapy be considered for chronic hepatitis B (CHB) patients with high viral load if a biopsy shows significant liver disease despite alanine aminotransferase (ALT) levels two times or less than the upper limit of normal (ULN). We evaluated the histological findings in CHB patients with high viral load and persistently normal or slightly elevated serum ALT levels. Between January 2003 and June 2006, 105 consecutive treatment‐naive patients with CHB who underwent ultrasonography‐guided percutaneous liver biopsy, had detectable serum HBV DNA (>105 copies/mL) in a direct hybridization assay and normal or slightly elevated serum ALT levels (≤2 × ULN) for at least 12 months were included in a prospective study. Histological assessment was based on the METAVIR scoring system. Significant histology was defined as fibrosis stage ≥F2 or necroinflammation grade ≥A2. Among the 105 CHB patients with high viral load and persistently normal or slightly elevated serum ALT levels for at least 12 months, significant fibrosis (F2–F4 fibrosis) was observed in 63 patients (60.0%) and the actual significant histology was found in 65 patients (61.9%). On multivariate analysis, serum ALT levels and age at which they entered the study were independent factors associated with significant histology. Odds ratios for significant histology increased progressively according to serum ALT levels and age. In conclusion, a large proportion of CHB patients with genotype C, high viral load and ALT ≤2 × ULN had significant liver disease on liver biopsy and should be considered for antiviral therapy.
1 FACTORS IMPACT ON CUSTOMERS ’ INTENTION AND USAGE TOWARDS MOBILE COMMERCE IN VIETNAM

Mobile Commerce plays a vital role in business nowadays. In Viet Nam, there is not many researches about M-commerce. Therefore, based on TAM model, this research investigates factors impact on customers’ intention and usage towards M-commerce.

Ott's protein osmotic pressure of serum and interstitial fluid in chickens (Gallus gallus): effect of age and gender

SUMMARY Protein, or colloid, osmotic pressure (COP) is of sufficient magnitude to exert a powerful effect on Starling forces across the capillary wall. Although avian skin lacks active mechanisms for fluid transmission, such as sweating, it is now hypothesized that passive oncotic forces may regulate fluid flow and distribution in the skin and related phenomena. In this study, serum protein profiles, as well as COP in serum (COPs) and in suction blister fluid (COPsbf), were determined in juvenile, young and adult female and male chickens. For assessing COP, the Ott-Ahlqvist equation was applied. This equation can formulate the effects of multiple serum proteins on COP, according to their molecular mass. The COP values determined in chickens were lower than those previously found in mammals. COPs increased with age in males, and was higher in adult males than in adult females. In contrast, COPsbf decreased with age in females, although it was better preserved in adult males. The age-dependent decrease in COP was associated with a parallel decrease in the concentration of α1-globulin and albumin, and a positive correlation between packed cell volume (PCV) and COP was found. It is concluded that ageing affects Ott's COP around the vessel wall, and that an oncotic mechanism preserves plasma volume. The preservation of COPsbf in males suggests better maintenance of the interstitial ground substance. Females seem to lose more of a tissue's COPs counteracting force than males, probably as a result of gender-specific changes in the composition of the interstitial matrix. Further studies are required to elucidate the structure and function of avian lymphatics and their role in skin rheology.
Sesamol-loaded solid lipid nanoparticles for treatment of skin cancer

Abstract Role of reactive oxygen species (ROS) in skin carcinogenesis is well documented. Natural molecules, like sesamol, with marked antioxidant potential can be useful in combating skin cancers. In vitro antiproliferative (using MTT assay) and DNA fragmentation studies in HL 60 cell lines, confirmed the apoptotic nature of sesamol. However, it showed a significant flux across the mice skin upon topical application, such that its local availability in skin is limited. Former is attributed mainly to its properties like small size, low molecular weight (138.28), and a sufficient lipid and water solubility (log P 1.29; solubility 38.8 mg/ml). To achieve its maximum epicutaneous delivery, packaging it into a suitable carrier system is thus indicated. Sesamol-loaded solid lipid nanoparticles (S-SLN) were thus prepared with particle size of 127.9 nm (PI: 0.256) and entrapment efficiency of 88.21%. Topical application of S-SLN in a cream base indicated significant retention in the skin with minimal flux across skin as confirmed by the in-vivo skin retention and ex-vivo skin permeation studies. In vivo anticancer studies performed on TPA-induced and benzo(a)pyrene initiated tumour production (ROS mediated) in mouse epidermis showed the normalization (in histology studies) of skin cancers post their induction, upon treatment with S-SLN.
Assessing Reliability of a Multi-Dimensional Scale by Coefficient Alpha

The purpose of the study was to assess internal consistency by calculating coefficient alpha. It presents the variation in coefficient alpha, depending on questionnaire length and the homogeneity or heterogeneity of the questionnaire. The maximum possible value for coefficient alpha was also calculated by the item elimination method. The study included 99 children aged 10. The children completed The Athletic Coping Skills Inventory – 28 (ACSI-28; Smith et al., 1995), which contains seven constructs: coping with adversity, coachability, concentration, confidence and achievement motivation, goal setting and mental preparation, peaking under pressure and freedom from worry. The results confirmed that the values of the alpha coefficient vary depending on the number and composition of items and the sample size. In terms of item structure, homogeneous constructs yielded lower values for the alpha coefficient (in a range from .48 to .61) than the questionnaire with all the constructs (alpha = .79), despite higher inter-item correlations. In terms of the number of items, the longer test generated higher alpha coefficients (alpha = .79) than the shorter test (half-sets of items = .60, .73, .69, .70). A higher overall value (alpha = .83) can be achieved by item elimination.
Title Measuring the coherence of normal and aphasic discourse production in Chinese using rhetorical structure theory (RST)

The study investigated the difference in discourse coherence between healthy speakers and speakers with anomic aphasia using Rhetorical Structure Theory (RST). The effect of genre types on coherence and potential factors contributing to the differences were also examined. Fifteen native Cantonese participants of anomic aphasia and their control matched in age, education and gender participated. Sixty language samples were obtained using the story-telling and sequential description tasks of the Cantonese AphasiaBank protocol. Twenty naïve listeners provided subjective ratings on the coherence, completeness, correctness of order, and clarity of each speech sample. Results demonstrated that the control group showed significantly higher production fluency, total number of discourse units, and fewer errors than the aphasia group. Controls used a richer set of relations than the aphasic group, particularly those to describe settings, to express causality, and to elaborate. The aphasic group tended to omit more essential information content and was rated with significantly lower coherence and clarity than controls. The findings suggested that speakers with anomic aphasia had reduced proportion of essential information content, lower degree of elaboration, and more structural disruptions than the controls, which may have contributed to the reduced overall discourse coherence.

How Does Precision Affect the Adoption of Energy Efficiency Practices ? – Evidence from the Field and Laboratory Data

Academic / Practical Relevance: The United States has long recognized the potential of energy efficiency to profitably reduce energy consumption in manufacturing and the Department of Energy (DOE) has initiated several programs to enhance energy efficiency in the industry. Despite this attention, research shows that many energy efficiency opportunities remain unexploited. Recently, scholars have emphasized that behavioral factors can facilitate the uptake of energy efficiency practices. Consequently, we embrace a behavioral perspective and demonstrate that a hitherto unexplored behavioral factor (i.e., precision) can affect the adoption of energy efficiency opportunities. By doing so, we contribute to the OM and energy efficiency literatures.
Mobilizing Referenda: The Effects of Direct Democracy on Youth Political Participation

This paper investigates determinants of adolescents’ political participation in two political systems. Political participation of adolescents is influenced by personal resources such as cognitive abilities as well as institutional context, for example the political system. In this study we examine the interplay of one systemic factor, namely whether the political system is a direct or representative democracy, and resources on the individual level: news media use and internal political efficacy. We apply a Most Similar Systems Design by comparing two largely similar countries (Netherlands and Switzerland) that differ in one critical institutional variable (representative versus direct democracy). The comparison between Switzerland and the Netherlands reveals that adolescents in Switzerland participate significantly more in political activities. The relationship between direct democratic institutions and political participation is partially mediated by political efficacy. However, the mediation only occurs if adolescents use news media regularly.
Application of the One-Dimensional Turbulence model to incompressible channel and pipe flow

Incompressible channel and pipe flow configurations are investigated using the One-Dimensional Turbulence (ODT) model, in which the 1-D domain is aligned with the wall normal direction. The framework for the application of ODT in planar and cylindrical coordinates is revisited for the temporal ODT channel and pipe flow configurations and a new spatial formulation is introduced. The calculation of the turbulent kinetic energy (TKE) budgets in ODT for the temporal and spatial formulations is reviewed for the planar channel flow and newly introduced in cylindrical pipe flow. Simulations are performed at three different friction Reynolds numbers, 550, 1000 and 2000 in order to compare ODT results in the planar and cylindrical formulation with Direct Numerical Simulations (DNS) from Chin et al. [Int. J. Heat Fluid Flow 45 (2014) 33-40] and Khoury et al. [Flow, Turbul. Comb. 91 (2013) 475-495]. ODT results are generated for both the temporal and spatial formulations for the normalized mean velocity profiles, streamwise RMS velocity profiles, wall normal Reynolds stress component, TKE production and dissipation budgets, and the pre-multiplied mean velocity gradient. DNS results are generally captured very well by ODT. This shows that ODT is a reduced order model that is able to capture a significant part of the flow dynamics in wall-bounded flows.
Channel Estimation for TDD/FDD Massive MIMO Systems With Channel Covariance Computing

In this paper, we propose a new channel estimation scheme for TDD/FDD massive MIMO systems by reconstructing (sometimes also referred to as covariance computing or covariance fitting) uplink/downlink channel covariance matrices (CCMs) with the aid of array signal processing techniques. Specifically, the angle parameters and power angular spectrum (PAS) of channel are extracted from the instantaneous uplink channel state information (CSI). Then, the uplink CCM is reconstructed and can be used to improve the uplink channel estimation without any additional training cost. By virtue of angle reciprocity as well as PAS reciprocity between uplink and downlink channels, the downlink CCM could also be inferred with a similar approach even for the FDD massive MIMO systems. Then, the downlink instantaneous CSI can be obtained by training toward the dominant eigen-directions of each user. The proposed strategy is applicable to various PAS distributions. Numerical results are provided to demonstrate the superiority of the proposed methods over the existing ones.
