Triple-Band Microstripline-Fed Printed Wide-Slot Antenna for WiMAX/WLAN Operations

A novel triple-band microstrip antenna design is introduced for WiMAX/WLAN applications. The proposed antenna has a moderate size of 38×39×0.79 mm 3 , yet offers quite well gain performance (5.6-8 dBi) over the operational bands. The antenna consists of a microstrip feed- line coupled to a pair of concentric rectangular loops, as well as a split-ring element inserted within a slotted ground plane, which may also be considered as a wide-slot antenna element. In the paper, the numerical antenna design along with the corresponding measurement results is presented. An equivalent circuit modeling of the proposed design along with empirical formulae relating antenna parameters with notch frequencies is also introduced to serve as a useful design guideline. Index Terms ─ Empirical formulae, equivalent circuit modeling, loop element, microstripline feed, multiband operation, printed wide-slot antenna, split-ring element, WiMAX, WLAN.
A developmental perspective on productive lexical knowledge in L2 oral interlanguage1

ABSTRACT This article reports on productive vocabulary development by instructed British learners of French over a five-year period (from age 13 to 18). Lexical diversity development was investigated through a semi-guided oral picture-based task. Results show that the students' lexical diversity (as measured by D) did significantly improve throughout the five years showing little sign of slower periods. Overall more noun types were observed than verb types in the composition of the lexicon throughout the study but with a consistent decrease in its proportion after Year 10. Further results using the Limiting Relative Diversity measure indicate that learners vary their use of nouns to a much larger extent than verbs. The discussion focuses on the noun-bias hypothesis and the use of different elicitation tasks.
An evaluation of structured snow-track surveys to monitor Eurasian lynx Lynx lynx populations

Abstract Counts of tracks that passively accumulate on a suitable substrate are commonly used to derive indices of large carnivore abundance. In this study we evaluate the suitability of a similar survey using multiple 3-km long transect-lines to detect changes in population size for Eurasian lynx Lynx lynx in central Norway. We used GIS methods to simulate the crossing of transect lines by lynx using real telemetry data from the study area. We compared the effect of transect-line placement (deliberate vs random), transect-line density, and the number of nights over which tracks can accumulate in the snow. For each scenario we evaluated both the probability of detecting lynx that are present in the survey area, and the power of the index to detect changes between consecutive surveys. Deliberately placed lines performed significantly better than randomly placed lines, and as expected, increases in line density and the period of track accumulation improved the outcome. Using three nights of track accumulation and the highest density of deliberately placed lines that we simulated (1/38 km2) indicated that both the probability of detecting individual lynx present within the survey area, and the power to detect a 33% change in population size between two surveys, were > 80%.
MANAGEMENT OF SELECTED POPULATIONS: FROM THEORY TO PRACTICE

The methodologies available for improving the balance between genetic gain and inbreeding rate in selected populations were briefly reviewed. Emphasis was given to the long-term contribution approach. uch an approach was adapted to the main selection steps of dairy cattle and pig breeding. Details of the appropriate procedures were given. A posteriori tests were carried out in corresponding real populations in order to assess their potential for saving genetic variability while maintaining the genetic gains at their observed values. Generally speaking, these procedures were able to decrease kinskip and inbreeding coefficients by about 20%.
Photothermal excitation of microcantilevers in liquid: effect of the excitation laser position on temperature and vibrational amplitude

Demands to improve the sensitivity and measurement speed of dynamic scanning force microscopy and cantilever sensing applications necessitate the development of smaller cantilever sensors. As a result, methods to directly drive cantilevers, such as photothermal or magnetic excitation, are gaining in importance. Presented is a report on the effect of photothermal excitation of microcantilevers on the increase in steady-state temperature and the dynamics of higher mode vibrations. First, the local temperature increase upon continuous irradiation with laser light at different positions along the cantilever was measured and compared with finite element analysis data. The temperature increase was highest when the heating laser was positioned at the free end of the cantilever. Next, the laser intensity was modulated to drive higher flexural modes to resonance. The dependence of the cantilever dynamics on the excitation laser position was assessed and was in good agreement with the analytical expressions. An optimal position to simultaneously excite all flexural modes of vibration with negligible heating was found at the clamped end of the cantilever. The reports findings are essential for optimisation of the excitation efficiency to minimise the rise in temperature and avoid damaging delicate samples or functionalisation layers.
Potentials of Rice Husk Ash for Soil Stabilization

Soil sample collected from Maikunkele area of Minna, classified as an A-7-6 lateritic soil on AASHTO classification was stabilized with 2-12% rice husk ash (RHA) by weight of the dry soil. Using British standard light (BSL) compaction energy level, performance of the soil-RHA was investigated with respect to compaction characteristics, California bearing ratio (CBR) and unconfined compressive strength (UCS) tests. The results obtained, indicates a general decrease in the maximum dry density (MDD) and increase in optimum moisture content (OMC) with increase in RHA content. There was also slight improvement in the CBR and UCS with increase in the RHA content. The peak UCS values were recorded at between 6-8% RHA, indicating a little potential of using 6-8% RHA for strength improvement of A-7-6 lateritic soil.
PRELIMINARY DATA ON PLATINUM GROUP ELEMENT AND GOLD IN THE HIGHLAND COMPLEX , SRI LANKA : A SEARCH FOR HIDDEN SULPHIDE SATURATION

Sulphide saturation in mafic-calcic magmatic melts has important implications on chalcophile element mineralization. Therefore, this study was undertaken as a preliminary investigation of the geochemistry of platinum group elements (PGE) and Au of MgOand CaO-rich gneisses from the Highland Complex (HC), Sri Lanka in order to constrain magmatic processes related to sulphide saturation. Here we report data of PGE (Re, Pd, Pt, Rh, Ru, Ir) and Au together with major and rare earth elements (REE) in magnesio-calcic granulites collected over a wide spatial distribution, along a NE-SW transect of the central HC. The studied samples belong geochemically, to two groups: (a) low magnesio-calcic (LMC) with low MgO (<13 wt %) and CaO (<12 wt %) and (b) high magnesio-calcic (HMC) with high MgO (>13 wt %) and Cao (>12 wt %). The HMC granulites have low overall REE abundances compared to the LMC granulites. The concentration of PGE and Au show a systematic positive correlation with increasing MgO contents. Between the HMC and LMC samples there is a clear distinction of Pt/Pd vs. MgO, in which the HMC group shows a negative correlation while the LMC samples display a positive correlation. The variation of the Pt/Pd shown by the HMC samples indicates that the ratio of Pt/Pd gradually increases with decreasing MgO content. Similar behavior can be observed in the Au vs. MgO plot for the LMC group. Further, in the Pd vs. MgO plot the HMC samples show a robust positive correlation with MgO content. These geochemical trends indicate that the PGE of the HMC samples are mainly controlled by a progressive segregation of an immiscible sulfide melt cluing a potential chalcophile mineralization. There is no evidence for sulphide saturation in the LMC group.
Title Targeted disruption of organic cation transporter 3 attenuates the pharmacologic response to metformin Permalink

Metformin, the most widely prescribed antidiabetic drug, requires transporters to enter tissues involved in its pharmacologic action, including liver, kidney, and peripheral tissues. Organic cation transporter 3 (OCT3, SLC22A3), expressed ubiquitously, transports metformin, but its in vivo role in metformin response is not known. Using Oct3 knockout mice, the role of the transporter in metformin pharmacokinetics and pharmacodynamics was determined. After an intravenous dose of metformin, a 2-fold decrease in the apparent volume of distribution and clearance was observed in knockout compared with wild-type mice (P , 0.001), indicating an important role of OCT3 in tissue distribution and elimination of the drug. After oral doses, a significantly lower bioavailability was observed in knockout compared with wild-type mice (0.27 versus 0.58, P , 0.001). Importantly, metformin’s effect on the plasma glucose concentration-time curve was reduced in knockout compared with wild-type mice (12 versus 30% reduction, respectively, P , 0.05) along with its accumulation in skeletal muscle and adipose tissue (P, 0.05). Furthermore, the effect of metformin on phosphorylation of AMP activated protein kinase, and expression of glucose transporter type 4 was absent in the adipose tissue of Oct3 mice. Additional analysis revealed that an OCT3 39 untranslated region variant was associated with reduced activity in luciferase assays and reduced response to metformin in 57 healthy volunteers. These findings suggest that OCT3 plays an important role in the absorption and elimination of metformin and that the transporter is a critical determinant of metformin bioavailability, clearance, and pharmacologic action.
Difference in seasonal variation of net precipitation between the Arctic and Antarctic regions

The difference in the climatological seasonal variation of the net precipitation (precipitation minus evaporation) between the Arctic and the Antarctic was evaluated using ECMWF reanalysis data. Evaluated for simplified polar caps (the regions poleward of 70°N and 67.5°S), over the Arctic, the net precipitation is large in the boreal summer, while over the Antarctic, it is large in the austral winter. The net precipitation depends strongly on the poleward transient moisture flux into the region, which is affected by both the meridional moisture gradient and eddy activity. Thus, the seasonal variation of the poleward transient moisture flux is determined by the relative amplitude of the moisture and eddy factors, that is, by the ratio of the amplitude of the seasonal variation to the annual mean. While both regions have similar relative amplitudes of the eddy factor, the moisture factor in the Arctic is much larger than in the Antarctic. The moisture factor explains the difference in the seasonal variation of the net precipitation.
Genetic and phenotypic variability of yield components in wheat, Triticum aestivum L.

The heritability, phenotypic variability and components of variance for spike length and number of spikelets per spike have been studied in 50 cultivars from different selection centers all over the world. The experiment was performed in randomized block design in three replications on the experimental field in two years. A total number of 60 plants have been analyzed in the full maturity stage. Average estimated values of spike length and number of spikelets per spike differed significantly among years and among cultivars. The highest average value of spike length had Mironovskaya 808 cultivar (V =14.5 cm), and the lowest value was found in Etoille de Choisy (J=8.1 cm) and San Pastore cultivar (V =8.2). During investigated periods the highest average value for number of spikelets/spike had Sava cultivar (V=28.2), and the lowest value expressed Frontana cultivar (V =19.2). The average variation coefficient for spike length was 8.0%, and for number of spikelets per spike was 7.5%. The lowest variability for spike length was established in Pernel cultivar (V=4.8%) and the highest in Lepenica cultivar (V=12.9%). The coefficient of variation for number of spikelets per spike ranged from 4.7% in Bankut 1205 to 12.4% in Norin 10 cultivar. The obtained heritability values in broad sense were fairly high for spike length (96.4%) and number of spikelets per spike (79.1%). Phenotypic analysis of variance indicated that genetic variance took a larger portion of the total phenotypic variability for spike length (81.82%) and for number of spikelets per spike (57.36%) than influence of environmental factors on expressing of analyzed yield components.
Performance Effects of Internal Audit Characteristics and Relationships in Nigerian Local Governments

The performance of local governments in Nigeria has been on the decline as service delivery to communities has become a challenged due to mismanagement and widespread corruption. Literature supports the value-adding role of internal audit and the ability of the function to enable an organization minimize opportunistic behaviours that are inimical to the performance of the organization. In view of this, the study examined the effect of internal audit characteristics and relationships on the performance of local governments in Nigeria. Self-reported questionnaires were used to obtain data from 301 heads of internal audit unit in local governments. The multiple regression analysis was utilized for testing the study's hypotheses. The results indicated that internal audit characteristics and internal audit relationship with management were positively and significantly related to performance. Also, collaboration between internal audit and external audit showed a negative and non-significant relationship with performance. Based on the findings, it was concluded that internal audit characteristics and internal audit relationship with management are important for internal audit value-adding capacity for improved performance of local governments in Nigeria.

The Hippocampal Engram as a Memory Index

The hippocampus encodes memories for past events, but the nature of the hippocampal code subserving this function remains unclear. A prevailing idea, strongly supported by hippocampal physiology, is the Cognitive Map Theory. In this view, episodic memories are anchored to spatial domains, or allocentric frameworks, of experiences, with the hippocampus providing a stable representation of external space. On the other hand, recent studies using Immediate Early Genes (IEGs) as a proxy of neuronal activation support the Memory Index Theory. This idea posits that the hippocampal memory trace serves as an index for a cortical representation of memory (a map for internal representation) and hypothesizes the primary hippocampal function is to reinstate the pattern of cortical activity present during encoding. Our recent findings provide a unitary view on these two fundamentally different theories. In the hippocampal CA1 region the activity of c-Fos expressing pyramidal neurons reliably reflects the identity of the context the animal is experiencing in an index-like fashion, while spikes from other active pyramidal cells provide spatial information that is stable over a long period of time. These two distinct ensembles of hippocampal neurons suggest heterogeneous roles for subsets of hippocampus neurons in memory.
“ Models in the Geosciences ”

The geosciences include a wide spectrum of disciplines ranging from paleontology to climate science, and involve studies of a vast range of spatial and temporal scales, from the deep-time history of microbial life to the future of a system no less immense and complex than the entire earth. Modeling is thus a central and indispensible tool across the geosciences. Here we review both the history and current state of model-based inquiry in the geosciences. Research in these fields makes use of a wide variety of kinds of models, including conceptual, physical, and numerical models, and more specifically cellular automata, artificial neural networks, agent-based models, coupled models, and hierarchical models. We note the increasing demands to incorporate biological and social systems into geoscience modeling, challenging the traditional boundaries of these fields. Understanding and articulating the many different sources of scientific uncertainty--and finding tools and methods to address them--has been at the forefront of much research in geoscience modeling. We discuss not only structural model uncertainties, parameter uncertainties, and solution uncertainties, but also the diverse sources of uncertainty arising from the complex nature of geoscience systems themselves. Without an examination of the geosciences, our philosophies of science and our understanding of the nature of model-based science are incomplete.
Polarization of seven MBM clouds at high Galactic latitude

We made R-band polarization measurements of 234 stars towards the direction of MBM 33-39 cloud complex. The distance of MBM 33-39 complex was determined as $120\pm10$ pc using polarization results and near-infrared photometry from the 2MASS survey. The magnetic field geometry of the individual cloud inferred from our polarimetric results reveals that the field lines are in general consistent with the global magnetic field geometry of the region obtained from the previous studies. This implies that the clouds in the complex are permeated by the interstellar magnetic field. Multi-wavelength polarization measurements of a few stars projected on the complex suggest that the size of the dust grains in these clouds is similar to those found in the normal interstellar medium of the Milky Way. We studied a possible formation scenario of MBM 33-39 complex by combining the polarization results from our study and from the literature and by identifying the distribution of ionized, atomic and molecular (dust) components of material in the region.
Recovery of aluminium from a hazardous waste by precipitation as boehmite

Boehmite was synthesized by a low temperature hydrothermal procedure, via sol-gel, from an aluminium hazardous waste (AHW). The method consisted of a first stage of acid digestion to solubilize the metal content, and a second stage of gel precipitation in alkaline medium. Several experiments were performed to study the effect of concentration, time and pH not only on the recovery of aluminium but on the purity of boehmite. A nanocrystalline boehmite was obtained as unique phase at pH8. At pH9 boehmite is obtained along with norstrandite. The complete characterization of samples was carried out by XRD, MEB, and TG/DTA. The procedure allows the recovery of 90% of the soluble aluminium content in the waste.
Idiosyncratic volatility, Australian stock returns and economy conditions: role of idiosyncratic volatility in asset pricing for Australian stock markets

This study examines the importance of idiosyncratic volatility in asset pricing for Australian stock returns from 1993 to 2010. We form an idiosyncratic volatility mimicking factor. In the presence of the Fama-French three-factor we find that the idiosyncratic volatility mimicking factor is priced in Australian stock returns over the sample period, implying that this type of volatility is significant in the pricing of Australian stocks. Further, we find that idiosyncratic volatility is priced during both economy expansions and contractions and our model captures greater variations in Australian stock returns during expansions than contractions.

PD/PID controller tuning based on model approximations: Model reduction of some unstable and higher order nonlinear models

A model reduction technique based on optimization theory is presented, where a possible higher order system/model is approximated with an unstable DIPTD model by using only step response data. The DIPTD model is used to tune PD/PID controllers for the underlying possible higher order system. Numerous examples are used to illustrate the theory, i.e. both linear and nonlinear models. The Pareto Optimal controller is used as a reference controller.
