EFFECT OF HALL CURRENTS AND RADIATION ABSORPTION ON UNSTEADY HYDRO MAGNETIC CHEMICALLY REACTING MICRO POLAR FLUID THROUGH A POROUS MEDIUM IN A ROTATING SYSTEM WITH VARIABLE SUCTION

We investigate the effect of combined influence of Hall currents and radiation absorption on unsteady hydro magnetic chemically reacting micropolar fluid through a porous medium in a rotating system with variable suction. The dimensionless governing equations for this investigation are solved by using perturbation technique. The effect of various dimensionless parameters entering the problem on the velocity, temperature, concentration and microrotation profiles across the boundary layer is presented through graphs. Also the result of the Skin friction, couple stress, the rate of heat and mass transfer at the wall are discussed for different parametric variations.
Spectral classification and distance determination of stars in nine southern Galactic $\ion{H}{ii}$ regions

Aims. We attempt to identify the ionising stars and to determine the photometric distances of nine southern Galactic H ii regions. Methods. We carried out optical spectroscopy and UBV photometry of the stellar content of these objects. The distance of individual stars were obtained by spectroscopic parallax. To avoid using a fixed value for the total-to-selective extinction ratio RV , the reddening AV was determined directly by the colour-difference approach by comparing our V apparent magnitudes and the JHK magnitudes from the 2MASS survey with the intrinsic colour indices. Results. As types O or B, we classified 24 of the 31 stars for which optical spectra were obtained. In particular, we identified two new O stars, one in RCW 98 and the other in RCW 99. The values of reddening obtained correspond to a mean 〈RV〉 = 3.44, which is about 10% higher than the value found for field stars. For three of the H ii regions studied (Bran 186, NGC 2626, and RCW 32), the distance estimates (with errors from 25% to 50%) were based on the data obtained for only one star. For the other six objects (NGC 3503, NGC 6334, RCW 55, RCW 87, RCW 98, and RCW 99), we obtained more precise photometric distances (with a mean error of ≈18%) calculated to be the median of the parallax distances obtained for two to six different stars in each nebulae. The parallax distances of individual stars belonging to a given nebula were similar to each other, with internal errors smaller than 5%, as a consequence of the method used to derive the reddening correction AV . The distance of 1.23 ± 0.30 kpc obtained for RCW 87 disagrees with the value of 7.6 kpc previously found. Conclusions. The dispersion in individual distance estimates for stars in a given nebula can be significantly reduced by calculating the reddening AV from a comparison between the V and the 2MASS JHK magnitudes instead of using AV = RV E(B−V) with a fixed value for RV . Therefore, more precise distances can be calculated with our proposed method.

A survey on decentralized steel industries

Article history: Received 1 June 2010 Received in revised form 10 September 2010 Accepted 14 September 2010 Available online 14 September 2010 During the past three decades there have been tremendous efforts on building steel factories on economic scales. The primary question is to find an economic scale for such plants which could also meet domestic demand. In this paper, we perform an empirical survey to find out whether building small steel factories are more suitable or setting up giant steel industries to meet regional demands. The results indicate that in many countries, building small steel plants based on the recent advances of technologies not only reduces the total cost of steel production but also it could significantly reduce the unnecessary transportation cost, providing cheaper labor, etc. This would lead to better competition which would increase the productivity. © 2010 Growing Science Ltd.

Reduced horn size in two wild trophy-hunted species of Caprinae

Abstract Factors affecting horn size in wild Caprinae are of biological and socio-economic interest because several species are selectively harvested on the basis of this heritable character. We analysed temporal trends in horn size in two mountain ungulates from south-eastern Spain, the Iberian wild goat Capra pyrenaica and the aoudad Ammotragus lervia. Trophy harvest is the main way in which these two species are exploited, although ‘poor-quality’ aoudads are also selectively removed. In recent years, both populations have suffered drastic decreases in number due to outbreaks of sarcoptic mange that led to the suspension of hunting for several years. Horn length in harvested male wild goats and aoudads declined during our study period. Over an 18-year period, the mean age of male goats shot as trophies rose by four years, while the age of trophy-harvested aoudads decreased by around six months over a 9-year period. Age and environmental conditions during the first few years of life explained 20% of variance in horn size in Iberian wild goat and 53% in aoudad. Population density early in life explained much of the reduction in goat horn size over time. Nevertheless, the major fall in population densities after the sarcoptic mange outbreaks did not lead to a recovery in horn size in either species. We suggest that the selective removal of large-horned animals may contribute to a decline in horn size. Other factors that may also explain the observed pattern include changes in interspecific competition, long-lasting maternal effects and reduced carrying capacity due to overgrazing during high density periods. Unfortunately, our data sets did not allow us to account for the possible effects of these factors.
Empirical Evaluation of Various Deep Neural Network Architectures for Time Series Forecasting

Time series forecasting is regarded amongst the top 10 challenges in data mining. Lately, deep learning based models have garnered a lot of attention from researchers in time series forecasting. However, which deep neural network architecture is most appropriate in time series forecasting domain has not been researched extensively.In this research performance of 4 deep neural network architectures MLP (Multilayer Perceptron), Traditional RNN (Recurrent Neural Network), LSTM (Long Short-Term Memory) and GRU (Gated Recurrent Units) were evaluated on two synthetic and two real-world time series exhibiting strong chaos, trend, and seasonality. Mackey Glass and Lorenz chaotic time series were simulated in this study to test our DNN models against chaos, while Apple Stock and Melbourne Minimum temperature were two real-world datasets showing increasing trend and seasonality. Experiments demonstrate that GRU based deep learning models outperform all other DNN models in forecasting both real world and synthetic time series
FAO-56 dual approach combined with multi-sensor remote sensing for regional evapotranspiration estimations

The aim of this paper is to use a dual, modified version of the FAO-56 methodology for the estimation of regional evapotranspiration. The proposed approach combines the FAO-56 technique with remote sensing. Two vegetation classes are considered in the evapotranspiration estimations. In the case of cereals, crop coefficients and cover fractions are estimated using relationships established with the Normalized Difference Vegetation Index (NDVI), retrieved from SPOT-VGT data. In order to characterize the soil, a relationship is established between evaporation and the retrieved soil moisture values, based on the ERS/WSC products developed by the University of Vienna. This approach is applied to a semi-arid region in central Tunisia (North Africa) and is validated over 1991–2007 period using simulations from the ISBA-A-gs physical SVAT model. The ISBA soil moisture outputs are validated using remotely sensed ERS/WSC products. Finally, a comparison is made between the ISBA and FAO approaches, for the same studied site.
Coopetition under alliance? Applying awareness-motivation-capability competitive dynamics perspective

Airline companies join airline alliances to cope with the high level of competition in the airline industry. However, pressure within an alliance is substantial. This study used competitor mapping and awareness-motivation-capability competitive dynamics to analyze airline alliances. The results revealed that alliances compete to recruit airline companies, and the power differences in the alliances are considerable; only a few of the airline companies within the alliance possess power. In addition, we interviewed 2 senior managers to confirm the results of the analysis. A detailed content analysis was performed to test each hypothesis. The findings revealed that companies with low market commonality and high resource similarity can cooperate through resource allocation. We also discovered that the main competitive action was derived from disallowing local airline companies to join an alliance. Leading companies in the alliance generally negotiated for the entire alliance indirectly. This research suggests that companies cooperate not only to control cost but also to increase service quality.
On Delay-Fractional-Dependent Stability Criteria for Takagi-Sugeno Fuzzy Systems with Interval Delay

This paper investigates stability program of Takagi-Sugeno fuzzy systems with interval time-varying delay via a variable delay decomposition approach. By developing a delay decomposition approach, both lower and upper bound information of the delayed plant states can be taken into full consideration; two novel delay-fractional-dependent stability criteria are obtained based on the direct Lyapunov method allied with an appropriate and variable Lyapunov-Krasovskii functional choice and with two different bounding techniques to estimate some integral terms in the time-derivative of the Lyapunov-Krasovskii functional. The first stability criterion is derived by utilizing the suitable and generalized integral inequalities, while the second stability condition is obtained by employing a scalar inequality, without any direct approximation. Particularly, the proposed results differ from previous ones since the positiveness of the Lyapunov-Krasovskii functional is guaranteed by new relaxed conditions. When applying these two stability criteria to check the stability of a T-S fuzzy system, it is shown through some numerical examples that the first stability condition can provide a larger maximum allowable delay bound than the second stability criterion, and both stability criteria yield less conservative than the existing ones.
Kinetics and Mechanism of Ni/Zeolite-Catalyzed Hydrocracking of Palm Oil into Bio-Fuel

Kinetics and mechanisms of Ni/zeolite-catalyzed cracking reaction of methyl ester palm oil (MEPO) were studied using a continuous flow-fixed bed reactor system at an atmospheric pressure. The catalyst was prepared by wet impregnation method with a solution of nickel nitrate hexahydrate as the precursor and zeolite as carrier. The characteristics of catalyst including active Ni metal content, crystallinity, total acidity, and porosity were evaluated. The reactions were performed with a varied hydrogen flow rate as a carrier gas as well as a reductant and reaction time. Liquid products were analyzed by GC. Analysis by GC-MS was only conducted on a product at hydrogen flow rate with the best conversion. It has been shown that the catalyst has a superior character for hydrocracking reactions of MEPO into green fuel. No considerable effect of hydrogen flow rate on the total conversion was observed. The tests showed that the kinetics of Ni/zeolite-catalyzed cracking reaction followed pseudo-first order kinetics. GC-MS analysis revealed the formation of light hydrocarbon products with C 6 -C 8 of aliphatic and cyclic components without oxygenates. Distribution of the product indicated that the cracking reaction as well as the isomerization of the products of hydrocracking occurred. Thus, Ni/zeolite-catalyzed cracking involved cracking /hydrogenation, isomerization, cyclization, and deoxygenation.

In Vitro Regeneration of Phyllanthus amarus Schum. and Thonn.: An Important Medicinal Plant

An efficient in vitro plant regeneration protocol was developed for the medicinally potent plant species Phyllanthus amarus Schum. and Thonn. (Euphorbiaceae) using nodal segment as explant. Maximum multiplication of shoots (15.275±0.96) was achieved on Murashige and Skoog’s medium supplemented with BAP (0.5 mg/l) after 3-4 weeks of inoculation. The shoots were separated from cluster and subcultured for their elongation on the same medium . In vitro flowering was also observed on the elongated shoots after 3–4 weeks of sub culturing on the shoot elongation medium. In vitro rooting was obtained on half strength MS medium supplemented with IBA (0.5 mg/l). Regenerated plants were successfully hardened and acclimatized, 80 % of plantlets survived well under natural conditions after transplantation. Key words: In vitro regeneration, multiple shoots, nodal segments, Phyllanthus amarus DOI: 10.3126/on.v7i1. 2557 Our Nature (2009) 7:110-115
Metacognitive Strategy Instruction and EFL learners’ Listening Comprehension Ability: A Tale of Two Genders

This research aimed to probe the effect of two different models of metacognitive strategy instruction on the listening performance of EFL learners in Iran. 83 intermediate EFL learners in four groups, two male and two female groups were the participants. The participants in the first experimental groups – a male and a female group – were undergone a ten-week treatment including the linear strategy instruction of metacognitive strategies. The focus was upon planning, monitoring, and evaluation. The participants in the second experimental group were trained according to Metacognitive Pedagogical Sequence proposed by Vandergrift and Goh (2012) for ten weeks, and participated in a course in which a sequence of tasks helped them work on their metacognitive awareness of the processes underlying L2 listening through peer interactions. Through a test of listening comprehension, data were collected and changes were tracked in learners’ listening performance before and after the program. According to the findings of the study metacognitive strategy instruction led to a significant improvement in the overall listening performance of the learners in both groups, that is, no significant difference was found between two groups of male and female learners. Moreover, it was shown that the Metacognitive Pedagogical Sequence and the manner in which metacognitive strategies were presented according to this model led to significantly higher listening performance of EFL learners who participated in this study.
Evolution of Baetiscidae (Ephemeroptera): current state of knowledge of the family

Recent discovery and description of fossil Baetiscidae has dramatically changed the biogeographical and evolutionary perspective of the family. Since the mid-eighteenth century until recently, the family has been known only from the Nearctic realm and all extant species of the family still remain geographically limited to this region. Here, we present the first parsimony algorithm generated cladistic analysis of the phylogeny of Baetisca based on external morphological characters of both larvae and adults. The results are compared with the previously published phylogeny of the genus and differences between the two studies are discussed. The southeastern United States is the centre of biodiversity of the genus where 11 of the 12 currently known nominal species have been reported. Biogeographical and evolutionary implications of the current geographic range of extant Baetisca and fossil species are discussed.

New laccase-producing fungi isolates with biotechnological potential in dye decolorization

Thirty six (36) native fungal strains from the state of Yucatan were first screened for ligninolytic activity on solid media containing ABTS. Molecular identification based on ITS rDNA region and PCR fingerprinting of seven selected fungi isolates were carried out. Molecular characterization based on genetic fingerprinting was helpful in determining unequivocally the differences between isolates at genera and species levels. The seven isolates showed ABTS oxidation zones in plates but only five strains produced extracellular laccase. The strains identified as Trametes hirsuta (GenBank accession numbers GQ280372 and GQ280373) showed the highest laccase production. The strain Bm-2 displayed the greatest laccase activity and dye decolourization ability in 72 h without the addition of mediators. Both the high laccase activity shown by Bm-2 and its ability to decolorize dyes are a good indication of its possible use in the treatment of textile effluents. Key words : Laccase, Trametes hirsuta, dye decolorization, PCR fingerprinting.
Estimating Mixed Logit Recreation Demand Models With Large Choice Sets

Discrete choice models are widely used in studies of recreation demand. They have proven valuable when modeling situations where decision makers face large choice sets and site substitution is important. However, when the choice set faced by the individual becomes very large (on the order of hundreds or thousands of alternatives), computational limitations make estimation with the full choice set intractable. Sampling of alternatives in a conditional logit framework is an effective method to limit computational burdens while still producing consistent estimates. This method is allowed by the existence of the independence of irrelevant alternatives (IIA) assumption. More advanced mixed logit models account for unobserved preference heterogeneity and overcome the behavioral limitations of the IIA assumption, however in doing so, prohibit sampling of alternatives. A method is developed where a latent class (finite mixture) model is estimated via the expectations-maximization algorithm and in doing so, allows consistent sampling of alternatives in a mixed logit model. The method is tested and applied to a recreational demand Wisconsin fishing survey.
Usage of watermarking techniques in medical imaging

In this paper, we present the usage of watermarking techniques in medical imaging, and especially for security goals, the watermarking is considered a great solution to protect the personal data of patients during the medical images and telemedicine data exchange. This paper is devised in two parts. The first one is reserved for an overview on image watermarking with a presentation of the most important requirements of watermarking (robustness, imperceptibility and capacity). We offer also the general scheme of watermarking with the two essential phases and different types of attacks. Furthermore, we present a classification of watermarking techniques based on various parameters such as: insertion domain, human perception and detection methods, in the end of the section we display some metrics and benchmarks for analysis the performance of the watermarking technique. The second part is reserved for the usage of watermarking techniques in medical imaging especially for integrity verification, authentication and data hiding, we also discuss a literature review on watermarking techniques for medical image. In addition, we present the concept of telemedicine and telehealth fields and the importance of watermarking in the modern health care.
UCLA’S GLOBAL ACCESS PROGRAM

In this article we analyse the role that innovation intermediaries play in supporting SMEs international sales and growth, by creating highly firm-specific learning and making it possible to access and accumulate strategic resources. We based our analysis on a set of 24 Italian firms that participated to an international program (GAP) organized by the business school of UCLA. Results show that thank to this intermediary, SMEs had been able to obtain different learning outcomes regarding the accumulation of new skills and organization competencies needed to enter a new market and to exploit complementary resources. This learning process followed a different pattern in entrepreneurial and managerial firms. The process created by the intermediary made it possible to match the firm’s idiosyncratic technological and market knowledge with complementary knowledge resources that the firm could not access through their local search dynamics In raising this evidence, the paper intends to provide a novelty contribution to open innovation studies, which regards the way innovation intermediaries can contribute to the growth and the organizational learning of SMEs.
