DISPERSION OF WAVES IN IMMERSED LAMINATED COMPOSITE HOLLOW CYLINDERS

Abstract A layer element method (LEM) is presented for analyzing frequency and group velocity dispersive behaviours of waves in a laminated composite cylinder surrounded by a fluid. The LEM applies finite elements to model the radial displacement of the cylinder and the radial pressure of the fluid, and complex exponentials to express the axial and circumferential displacements of the cylinder as well as the axial and tangential pressures of the fluid. The dispersive equation for the fluid-loaded cylinder follows from variational techniques. The frequency and group velocity dispersive relationships of the fluid-coupling cylinder are obtained by means of the Rayleigh quotient. Numerical results are given for hybrid laminated composite cylinders and cylindrical shells submerged in water. The addition of the fluid is proven to have considerable impact on the group velocity spectra of waves in laminated composite cylinders.
Empirical linkage between oil price and stock market returns and volatility: Evidence from international developed markets

This paper examines empirically whether oil price shocks impact stock market returns. Using monthly data for eight developed countries from January 1991 to September 2013, strong negative connections between oil price and stock market returns are found in seven of the selected countries. Oil price changes are without significant effect on the stock market of Singapore. On the volatility of returns, the changes in oil prices are significant for six markets and they have not much effect on the others.
RADIOPROTECTION BY TEMPOL: STUDIES ON TISSUE ANTIOXIDANT LEVELS, HEMATOPOIETIC AND GASTROINTESTINAL SYSTEMS, IN MICE WHOLE BODY EXPOSED TO SUB- LETHAL DOSES OF GAMMA RADIATION

Background: Ionizing radiation induces the production of reactive oxygen species (ROS), which play an important causative role in cell death. Wholebody exposure of mice to gamma radiation leads to diminution of tissue antioxidant defense systems; increases the peroxidative damage to membrane lipids and damages the haematopoietic and gastrointestinal systems. Tempol (TPL), a cell membranepermeable amphilite nitroxide, shown to protect against cell injury caused by ROS was studied for its radioprotective effects. Materials and Methods: Animals were administered with TPL at doses of 100 or 200 mg/kg body weight p.o 10 minutes prior to sub- lethal doses (4 or 6 Gy) of whole body gamma radiation exposure. Results: Tempol prevented the radiation induced depletion in RBC and total WBC counts, glutathione content in blood and bone marrow cellularity. TPL also protected the tissue antioxidant system and me mbrane lipids from the radiation-induced damages. An enhanced spleen colony formation and spleen weight recovery were also observed in radiation exposed mice administered with TPL. The compound also protected the epithelial cells of the gastrointestinal tract from the radiation-induced structural alterations. Conclusion: These preclinical data indicate that TPL may have its potential as a radioprotector during radiation exposure scenarios. Iran. J. Radiat. Res., 2012; 10(1): 1­10

The Effect of Conventional Block Pavement (CBP) on Surface Runoff

As cities continue to grow, the amount of impermeable surfaces increase. This in turn increases the risk of local flooding. However, there are solutions that deal with this problem. One solution is to replace impermeable surfaces with so called conventional block pavement (CBP) which allows water to infiltrate into the ground. The surface runoff will be reduced as well as the problems of local flooding. The aim of this study is to quantify the effect of an entire CBP-structure on runoff characteristics such as frequency, duration, volume and peak flow. This has been conducted by simulating long-term rainfall runoff for 16 years in the software EPA-SWMM 5.0. 022. First, a literature review was carried out in order to find relevant input data to the model. Second, the model was run and several sensitivity analyses were performed where different parameters related to the CBP-structure were varied within a reasonable range to see their effect on runoff. The following parameters were altered; resolution of infiltration rates, initial losses, surface slope, void ratio of the storage layer, height of the storage layer and finally conductivity of the native soil below the storage layer. It was seen that the resolution of infiltration rates only had little effect on peak flows, runoff volume and duration. Parameters that showed a great impairment to the runoff characteristics were a reduction in storage height or a change in initial losses. The most dramatic effect was seen using a very low conductivity corresponding to clay. This resulted in an increase of all runoff characteristics; frequency, duration, peak flows and total runoff. When changing from a conductivity corresponding to silt to a conductivity of sand, the total runoff was reduced by 11%. A recommendation followed by this consequence is to always use a drainage pipe at the bottom of the storage layer to enable a faster drainage and thereby reduce runoff from the CBPstructure.
How Responsive to Prices is the Supply of Milk in Malawi

Dairy is a key investment sector for the Government of Malawi. Advocacy institutions operating in the country have successfully lobbied for increasing the duty applied for powder milk, with the aim of improving the price received by farmers. It should be noted that whilst an increase of the price paid to farmers would rise their revenues (assuming the same amount of milk delivery), it might also bring additional blessings, in the sense that if farmers respond to prices, they may rise their revenues beyond the increase in prices, and furthermore, they would expand their delivery of milk to processors offsetting the imports of powder milk and reducing their idle capacity in factories. Hence, the purpose of this paper is to measure the responsiveness of the deliveries of milk at the milk bulking groups to prices paid to farmers (i.e., the elasticity of supply faced by processors). This is done using a unique dataset that comprises information by milk bulking group from January 2009 to February 2013. The results indicate that the supply of milk is price responsive. The price elasticity in the short term is equal to 0.6 and in the long term is 1.44. This indicates that farmers’ revenues not only benefit from an increase in the price of milk but also from the increase in the quantity produced. Furthermore, it indicates the possibility that domestic producers could offset imports of milk powder by processors, although answer to this requires further research.
Comparative Microseismic Interpretation of Hydraulic Fractures

Summary Microseismic monitoring is often used to evaluate differences in hydraulic fracturing, that result from either changes in the stimulation or geologic setting. Often the various microseismic images of individual fracs are each separately interpreted for fracture geometry, and then these absolute interpretations of the various fracs are compared. However, comparisons can be made of variations in specific fracture dimensions between each image, including using statistical tests to quantify significance of relative differences. Such a relative comparative interpretation is more robust and relies on a simpler assessment of the location precision, in contrast to the need to consider all aspects of location accuracy for absolute interpretations. The resulting comparative microseismic interpretation can be used as part of a comparative hydraulic fracture evaluation to test the response to different designs and ultimately optimize the stimulation.
Particular structure of an epiphytic diatom assemblage living on Ploclamium cartilagineum (Lamoroux) Dixon (Rhodophyceae: Gigartinales)

This is the first record of an epiphytic diatom assemblage of Ploclamium cartilagineum . Fifteen years ago observations on a specimen of P. cartilagineum revealed that large diatom of certain taxa occurred abundantly on its branches, and suggested also that it may harbor a particular diatom assemblage. Thus, we set out objective into identifying all the diatom taxa in the assemblage represented on the same P. cartilagineum specimen, and to determine their proportional abundances. Overall 46 taxa of epiphytic diatoms were identified. The diatom assemblage was characterized by abundant large forms such as Gephyria media , and Hyalodiscus punctatus a new record for the region, and the small form Cocconeis californica . Also include is, Grammatophora macilenta a new record for the region. Hitherto rare taxa in the region were very common such as Rhabdonema adriaticum, Campylopyxys garkeana, and Melosira polaris/Melosira sol . Although the estimated species richness and diversity values are high as in other assemblages of benthic diatoms, its basic structure (floristics) in which large forms rival the smaller forms in number, makes this assemblage particular. Estructura particular de una asociacion de diatomeas epifitas sobre Ploclamium cartilagineum (Lamoroux) Dixon (Rhodophyceae: Gigartinales) Se presenta el primer registro de diatomeas epifitas de Ploclamium cartilagineum . Hace quince anos se observo que sobre las ramas de un especimen de P. cartilagineum habitaban abundantes taxa de diatomeas de gran tamano, lo que sugirio que hospedaba una asociacion particular de diatomeas. Bajo el objetivo de identificar todos los taxa representados de diatomeas en el mismo especimen y determinar sus abundancias proporcionales en la asociacion, se identificaron 46 taxa, de las cuales dos formas grandes resultaron abundantes: Gephyria media , y Hyalodiscus punctatus un nuevo registro para la region; asi como Cocconeis californica , una forma pequena. Asimismo, se agrego un nuevo registro para la region con Grammatophora macilenta . Varios taxa considerados raros hasta antes de este estudio fueron muy comunes, como Rhabdonema adriaticum, Campylopyxys garkeana, y Melosira polaris/Melosira sol , entre otros. Aunque la riqueza y diversidad de especies fueron elevadas (tipicas) como en otros habitats bentonicos, su estructura basica (floristica) en donde formas grandes son tan abundantes como las pequenas define una asociacion particular.
THE SURFACES OF PLUTO AND CHARON DALE P. CRUIKSHANK, TED L. ROUSH and JEFFREY M. MOORE

Much of the surface of Pluto consists of high-albedo regions covered to an unknown depth by fl-N2 contaminated with CI--I4,CO, and other molecules. A portion of the exposed surface appears to consist of solid HzO. The remainder is covered by lower albedo material of unknown composition. The N2 ice may occur as polar caps of large extent, leaving ices and other solids of lower volatility in the equatorial regions. The low-albedo material found primarily in the equatorial regions may consist in part of solid hydrocarbons and nitriles produced from Nz and CI-L, in the atmosphere or in the surface ices. Alternatively, it may arise from deposition from impacting bodies and/or the chemistry of the impact process itself. Charon's surface is probably more compositionally uniform than that of Pluto, and is covered by I"/20 ice with possible contaminants or exposures of other materials that are as yet unidentified. The molecular ices discovered on Pluto and Charon have been identified from nearinfrared spectra obtained with Earth-based telescopes. The quantitative interpretation of those data has been achieved through the computation of synthetic spectra using the Hapke scattering theory and the optical constants of various ices observed in the laboratory. Despite limitations imposed by the availability of laboratory data on ices in various mixtures, certain specific results have been obtained. It appears that CI--_ and CO are trace constituents, and that some fraction of the CI'_ (and probably the CO) on Pluto is dissolved in the matrix of solid Nz. Pure _ probably also
Potential effects of climate change on stand development in the Pacific Northwest

Long-term climate and stand structure records and projections from a simulation model are used to explore effects of predicted changes in temperature on forest development in the Pacific Northwest. Few climate trends have occurred during the past 92 years, although there have been variations in September temperatures. The lack of climate trends makes it impossible to relate past changes in stand development to climate. Measures of stand development from six long-term forest plots over the past 7 decades are typical of Douglas-fir stands: stem density declines, leaf area stabilizes, aboveground biomass increases, and shifts in size distribution occur. These changes are consistent with patterns of natural succession. A computer model projected forest development under two climate scenarios: current temperature conditions and temperature warming (such as that predicted under a doubling of atmospheric CO2). The model predicted changes in species composition, leaf area, and stem density in response to temperat.
Hyperspectral Imaging for Differentiating Glyphosate-Resistant and Glyphosate-Susceptible Italian Ryegrass

Glyphosate is widely used in row crop weed control programs of glyphosate-resistant (GR) crops. With the accumulation of glyphosate use, several weeds have evolved resistance to glyphosate. In order to control GR weeds for profitable crop production, it is critical to first identify them in crop fields. Conventional method for identifying GR weeds is destructive, tedious and labor-intensive. This study developed hyperspectral imaging for rapid sensing of Italian ryegrass (Lolium perenne ssp. multiflorum) plants to determine if each plant is GR or glyphosate-susceptible (GS). In image analysis, a set of sensitive spectral bands was determined using a forward selection algorithm by optimizing the area under the receiver operating characteristic between GR and GS plants. Then, the dimensionality of selected bands was reduced using linear discriminant analysis. At the end the maximum likelihood classification was conducted for plant sample differentiation of GR Italian ryegrass from GS ones. The results indicated that the overall classification accuracy is between 75% and 80%. Although the accuracy is lower than the classification of Palmer amaranth (Amaranthus palmeri S. Wats.) in our previous study, this study provides a rapid, non-destructive approach to differentiate between GR and GS Italian ryegrass for improved site-specific weed management.
Consideration the effect of metallic nanoparticles shapes in light trapping by plasmonic solar cells

In this paper we have done a rigorous study on the thin film solar cells to enhance the absorption of the cells. Plasmonic solar cells have higher absorption despite use of less material. The action mechanism in plasmonic solar cells is based on the resonance of the localized surface plasmons by metallic nanoparticles. The purpose of this article is consideration the effect of metallic nanoparticles shapes on the absorption of the cells. We realize that the nanorods exhibit higher absorption efficiency in respect to the other nanoparticles.
How much motion is too much motion? Determining motion thresholds by sample size for reproducibility in developmental resting-state MRI

A constant problem developmental neuroimagers face is in-scanner head motion. Children move more than adults and this has led to concerns that developmental changes in restingstate connectivity measures may be artefactual. Furthermore, children are challenging to recruit into studies and therefore researchers have tended to take a permissive stance when setting exclusion criteria on head motion. The literature is not clear regarding our central question: How much motion is too much? Here, we systematically examine the effects of multiple motion exclusion criteria at different sample sizes and age ranges in a large openly available developmental cohort (ABIDE; http://preprocessed-connectomesproject.org/abide). We checked 1) the reliability of resting-state functional magnetic resonance imaging (rs-fMRI) pairwise connectivity measures across the brain and 2) the accuracy with which we can separate participants with autism spectrum disorder from typically developing controls based on their rs-fMRI scans using machine learning. We find that reliability on average is primarily sensitive to the number of participants considered, but that increasingly permissive motion thresholds lower case-control prediction accuracy for all sample sizes. ‡ § | ¶,# © Leonard J et al.

Coping with conflicts in an optimistically replicated file system

Coda is a scalable distributed Unix file system that provides high availability through the use of two distinct but complementary mechanisms. One mechanism, server replication, stores copies of a file at multiple servers. The other mechanism, disconnected operation, is a mode of execution in which a caching site temporarily assumes the role of a replication site. Disconnected operation is particularly useful for supporting portable workstations. Both mechanisms are forms of optimistic replication. Coda allows potentially conflicting updates to be made in each network partition during failures. This strategy is acceptable for two reasons. First, sequential write-sharing of data within a short period of time is relatively infrequent in Unix. Second, Coda provides mechanisms to minimize the inconvenience caused by conflicting updates. The author focuses on the mechanisms in Coda to cope with conflicts and describes experience in implementing them. <<ETX>>
Refined Agent Model Using Shape-Based Grained Structure: Application to Membrane Molecules

Multi-agent model is well-known to suit design of complex systems. This paradigm allows describing autonomous entities to interact together directly or through their environment. It is specially adapted to design 3D simulations taking into account spatial constraints on agents. In this work, we have designed a multi-agent model which adds a feature to the classical representation of agent: a body, encapsulating a physical model of the agent. We have applied this model to lipids and proteins belonging to the inner mitochondrial membrane, a biological membrane. Information provided by atomic structures is available through international databases and has been used to design a shape-based grain model for the agent body. We selected a model with three grains per molecule in which each grain is characterized by a type determining how they interact together and consequently the agent behaviors. Lipids and two kinds of protein structures have been described within this model allowing us to simulate their organization in membranes.
Faster Online Learning of Optimal Threshold for Consistent F-measure Optimization

In this paper, we consider online F-measure optimization (OFO). Unlike traditional performance metrics (e.g., classification error rate), F-measure is non-decomposable over training examples and is a non-convex function of model parameters, making it much more difficult to be optimized in an online fashion. Most existing results of OFO usually suffer from high memory/computational costs and/or lack statistical consistency guarantee for optimizing F-measure at the population level. To advance OFO, we propose an efficient online algorithm based on simultaneously learning a posterior probability of class and learning an optimal threshold by minimizing a stochastic strongly convex function with unknown strong convexity parameter. A key component of the proposed method is a novel stochastic algorithm with low memory and computational costs, which can enjoy a convergence rate of O(1/√n) for learning the optimal threshold under a mild condition on the convergence of the posterior probability, where n is the number of processed examples. It is provably faster than its predecessor based on a heuristic for updating the threshold. The experiments verify the efficiency of the proposed algorithm in comparison with state-of-the-art OFO algorithms.
