Modelling the response in streamflow to increased forestry plantations

Plantation forestry is an important land use in Australia which has the potential to reduce water yields compared with existing agricultural use. However, because of the biophysical complexity of landscapes, the hydrological impact of plantation expansion will vary between catchments and between locations within catchments. This paper investigates whether incorporating the history of plantation expansion in a catchment improves the prediction of streamflow by capturing the lag in catchment water balance and streamflow response in response to changes in plantation area and age. The study area for this project was the Glenelg Hopkins Region, South West Victoria, Australia; specifically the Crawford River, Eumeralla River and Darlot Creek. These catchments were selected as they were historically dominated by pasture based agricultural systems (>60%) and had seen a significant increase in plantation forestry over the last 10-15 years. The plantation history was estimated using the best available data, including an analysis of plantation data supplied by Green Triangle plantation growers as well as data from miscellaneous sources such as aerial photography and vegetation cover data. The majority of plantations in the Darlot Creek ( 0.7). In addition the incorporation of timing and pattern of plantation history demonstrated a small, consistent improvement in temporal streamflow predictions in each of the three catchments, with the results demonstrating a delayed pattern (4-5 years) in streamflow response consistent with the timing and pattern of plantation history. Due to the hydrological complexity of landscapes, the impact on streamflow of future plantation expansion will vary across the landscape; CAT presents a valuable tool for investigating the potential impacts of future plantations.
Bacterial resistance in bats from the Phyllostomidae family and its relationship with unique health

ABSTRACT: The Phyllostomidae family is important among the bats found in Brazil, with several species and diverse eating habits, and is the only one to have frugivorous representatives. These bats can be found in urban and in wild life environments in search for the best reproductive and feeding conditions. The versatility of environments can be associated with the incidence and/or distribution of some diseases through pathogenic agents. The present paper has the purpose to identify the oral and perianal microbiota and to detect the bacterial resistance of frugivorous bats captured near communities inhabited by humans in the northwestern region of the state of Paraná. A total of 68 bats were captured, belonging to four species of the Phyllostomidae family, namely Artibeus lituratus, Artibeus planirostris, Carollia perspicillata and Sturnira lillium, originated from forest fragments in the micro region of Umuarama, state of Paraná. A total of 64 isolates from oral bacteria and 39 from perianal region were submitted to identification. They were later submitted to a susceptibility test to 22 human and veterinary antimicrobials. The most prevalent bacteria were Escherichia coli 33.3% in the oral region, and 35.90% in the perianal region, Enterobacter aerogenes 12.7% and 5.13%, Enterobacter agglomerans 7.9% and 10.25%, and Serratia liquefaciens 9.5% and 5.13% in the oral and perianal region respectively. All bat species studied had resistant strains, with a few of them presenting multi-resistance to antimicrobials. The species with the highest multi-resistance index to antimicrobials was Carollia perspicillata, with three strains of the oral region resistant to 15 antimicrobials; it also presented two strains in the perianal region, which were resistant to 13 and 10 antimicrobials respectively. Based on the results found, it is possible to conclude that the oral and perianal microbiota of bats is composed of several enterobacterial species resistant to one or several antimicrobials used in human and veterinarian medicine. This is an issue and a future warning for unique health, since high percentages of resistance were found against antimicrobials broadly used, such as ampicillin, amoxicillin and amoxicillin+clavulonate.
Data-driven model of the cosmic-ray flux and mass composition from 10 GeV to $10^{11}$ GeV

We present a new parametrization of the cosmic-ray flux and its mass composition over an energy range from 10 GeV to $10^{11}$ GeV. Our approach is data-driven and relies on theoretical assumptions as little as possible. We combine measurements of the flux of individual elements from high-precision satellites and balloon experiments with indirect measurements of mass groups from the leading air shower experiments. To our knowledge, we provide the first fit of this kind that consistently takes both statistical and systematic uncertainties into account. The uncertainty on the energy scales of individual experiments is handled explicitly in our mathematical approach. Part of our results is a common energy scale and adjustment factors for the energy scales of the participating experiments. Our fit has a reduced $\chi^2$-value of 0.5, showing that experimental data are in good agreement, if systematic uncertainties are considered. Our model may serve as a world-average of the measured fluxes for individual elements from proton to iron from 10 GeV to $10^{11}$ GeV. It is useful as an input for simulations or theoretical computations based on cosmic rays. The experimental uncertainties of the input data are captured in a covariance matrix, which can be propagated into derived quantities.
Proactive Hybrid HVDC Breakers - A key Innovation for Reliable HVDC Grids

SUMMARY Existing mechanical HVDC breakers which are capable of interrupting DC currents within several tens of ms are too slow to fulfil the requirement of a reliable DC grid. Semiconductor based DC breakers easily overcome the limitations in operation speed but generate large transfer losses typically in the range of 30% of the losses of a voltage source converter station. To overcome these obstacles a hybrid HVDC breaker is proposed in this paper. The alternative design has negligible conduction losses while preserving fast current interrupting capability. By intelligent internal control, the same performance regarding clearing a DC fault can be obtained as with a pure IGBT DC breaker. This paper presents a detailed description of the proposed hybrid DC Breaker, its design principles and proactive control with particular focus on the reliability of the concept. The modular design of the hybrid DC breaker for HVDC applications is described and results from prototype testing are presented. Furthermore, the application of the hybrid DC breaker associated with the design of a DC switchyard is discussed.
Development and mineral nutrition of gerbera plants as a function of electrical conductivity

The control of substrate salinity is important for agricultural crops and, among the methods used, is the management of electrical conductivity of the substrate solution, which can be used as an indirect measure of the amount of salts and nutrients available or not for the plants. The objective of this study was to assess the effect of EC levels on the development, concentration and accumulation of nutrients in potted (1.3 L) gerbera ( Gerbera jamesonii ). The study was conducted in a greenhouse in a randomized block design, with five treatments (EC of 1.0, 2.0, 3.0, 4.0 and 5.0 dS m-1) and four replications. The quadratic function of the applied EC was obtained for leaf number and diameter, and the linear function, for inflorescence diameter. The nutrients in plant tissue increased linearly with the increasing level of EC, except for potassium and sulfur. The decreasing order for macronutrient levels was K>N>Ca>P>Mg>S, indicating the importance of potassium. Production parameters were little affected by the concentration of the nutrient solution. Therefore, it can be concluded that, with the increase in nutrients as a function of EC elevation, a luxury uptake can occur, with no representative on qualitative aspects.
Measuring the Implicit Value of Subsurface Mineral Rights in Eastern Ohio A Hedonic Model of Agricultural Land Sales in Belmont County Undergraduate

Shale gas development has proliferated in eastern Ohio, leading to questions about the economic impacts of the influx of entities seeking to explore and extract minerals in the region. A major source of economic gain for landowners in these areas is direct revenue from the purchasing and leasing of mineral rights by the mineral extraction industry. However, there is a history of mineral development in Eastern Ohio, implying the existence of split estates, situations in which the surface and subsurface rights for a given parcel of land are separately owned. While mineral rights are directly traded in the market, their implicit value as derived from the land and housing market may differ from this explicit market price. This paper attempts to evaluate the willingnessto-pay for a land parcel severed from the subsurface rights by estimating a hedonic model of agricultural land sales in Belmont County, Ohio. The findings of this research are inconclusive; while the dummy variable indicating the existence of a split estate is insignificant in all hedonic model specifications, measurement error and potential endogeneity may bias this result. However, other findings of the research corroborate the findings of literature in this subject area. This paper discovers a significant, positive relationship between permitted well density and sales price, and a consistently negative relationship between producing well density and sales price. These findings may indicate the existence of speculation in the land market, i.e., situations in which land in regions expecting payments for royalties and mineral rights appreciate in value, but those within the county where the development phase of shale production has passed are depreciating in value. Further research should focus on controlling for endogeneity and exploring interesting behavior discovered in land sales records, such as the observed propensity to buy full land parcels and split the estate shortly after sale.
A Meta-Analysis of the Cultural Propositions about Conflict Management Styles in Face-Negotiation Theory

Among the most influential intercultural communication theories is Ting-Toomey's face-negotiation theory. The theory has undergone a number of refinements over the past two decades and has emerged as one of the most cited theories in intercultural business communication research. The theory posits that face or "identity respect and other-identity consideration" is maintained and negotiated in communications and interactions of members of all cultures; however, it is perceived and enacted differently across cultures as a function of the cultural dimensions of individualism and power distance. Our study is a meta-analysis of all research that we could find that has been conducted about the cultural propositions related to conflict management styles in face-negotiation theory. Specifically, these propositions state that individualist cultures tend to use more dominating conflict management styles whereas collectivist cultures tend to use more integrating, compromising, avoiding, and obliging conflict management styles. We integrate findings across studies to answer the degree to which these theoretical propositions are answered by empirical research.
Improved Production of Bacterial Cellulose From Gluconacetobacter Persimmonis GH-2

Bacterial cellulose produced by members of the genus Gluconacetobacter displays unique properties including high mechanical strength, high water holding ability, high crystallinity, and an ultra-fi ne and highly pure fi ber network structure. It has many potential applications in biomedical, biosensor, food, textile and other industries. A cellulose producing strain isolated from nata sample (a desert) was identifi ed as Gluconacetobacter persimmonis (GH-2) based on biochemical studies and 16S rDNA complete sequence analysis. The strain produced 5.14 g/L of cellulose in standard medium under stationary growth conditions. For effective production of cellulose from the strain, various carbon and nitrogen sources were investigated in fl ask cultures under stationary conditions of incubation. Among various carbon sources glucose, fructose, sucrose, mannitol and inositol were found to be suitable for growth and cellulose production. The strain utilized a wide range of organic nitrogen sources such as peptone, casein hydrolyzate, beef extract, and malt extract for growth and cellulose production. The optimum pH and temperature for BC production by the strain were observed to be 5.5 and 30oC respectively. The organism was also found to produce substantial amount of cellulose under aerated and agitated culture conditions. Batch fermentation for cellulose production using glucose as a carbon source by the strain was carried out in a laboratory-scale fermenter. The strain produced 6.71 g/L cellulose in the fermenter which was 30% higher than that of the yield under stationary conditions of growth.
Dose-response effects of omega-3 fatty acids on triglycerides , inflammation , and endothelial function in healthy persons with moderate hypertriglyceridemia 1 – 3

Background: Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) have been shown to reduce cardiovascular mortality at a dose of ’1 g/d. Studies using higher doses have shown evidence of reduced inflammation and improved endothelial function. Few studies have compared these doses. Objective: The objective of this study was to compare the effects of a nutritional dose of EPA+DHA (0.85 g/d) with those of a pharmaceutical dose (3.4 g/d) on serum triglycerides, inflammatory markers, and endothelial function in healthy subjects with moderately elevated triglycerides. Design: This was a placebo-controlled, double-blind, randomized, 3-period crossover trial (8 wk of treatment, 6 wk of washout) that compared the effects of 0.85 and 3.4 g EPA+DHA/d in 23 men and 3 postmenopausal women with moderate hypertriglyceridemia
Near-Surface Density Currents Observed in the Southeast Pacific Stratocumulus-Topped Marine Boundary Layer*

AbstractDensity currents (i.e., cold pools or outflows) beneath marine stratocumulus clouds are characterized using 30 days of ship-based observations obtained during the 2008 Variability of American Monsoon Systems (VAMOS) Ocean–Cloud–Atmosphere–Land Study Regional Experiment (VOCALS-REx) in the southeast Pacific. An air density increase criterion applied to the Improved Meteorological (IMET) sensor data identified 71 density current front, core (peak density), and tail (dissipating) zones. The similarity in speeds of the mean density current propagation speed (1.8 m s−1) and the mean cloud-level advection relative to the surface layer wind (1.9 m s−1) allowed drizzle cells to deposit elongated density currents in their wakes. Scanning Doppler lidar captured prefrontal updrafts with a mean intensity of 0.91 m s−1 and an average vertical extent of 800 m. Updrafts were often surmounted by low-lying shelf clouds not connected to the overlying stratocumulus cloud. The observed density currents were 5–10 time.
A Scalable Priority-Aware Approach to Managing Data Center Server Power

Power management is a key component of modern data center design. Power managers must (1) ensure the costand energy-efficient utilization of the data center infrastructure, (2) maintain availability of the services provided by the center, and (3) address environmental concerns associated with the center’s power consumption. While several power management techniques have been proposed and deployed in production data centers, there are still many challenges to comprehensive data center power management. This is particularly true in public cloud environments, where different jobs have different priority levels, and where high availability is critical. One example of the challenges facing public cloud data centers involves power capping. As power delivery must be highly reliable and tolerate wide variation in the load drawn by the data center components, the power infrastructure (e.g., power supplies, circuit breakers, UPS) has high redundancy and overprovisioning. During normal operation (i.e., typical server power demands, and no failures in the center), the power infrastructure is significantly underutilized. Power capping is a common solution to reduce this underutilization, by allowing more servers to be added safely (i.e., without power shortfalls) to the existing power infrastructure, and throttling power consumption in the infrequent cases where the demanded power exceeds the provisioned power capacity to avoid shortfalls. However, state-of-the-art power capping solutions are (1) not directly applicable to the redundant power infrastructure used in highly-available data centers; and (2) oblivious to differing workload priorities across the entire center when power consumption needs to be throttled, which can unnecessarily slow down high-priority work. To address this need, we develop CapMaestro, a new power management architecture with three key features for public cloud data centers. First, CapMaestro is designed to work with multiple power feeds (i.e., sources), and exploits server-level power capping to independently cap the load on each feed of a server. Second, CapMaestro uses a scalable, global priority-aware power capping approach, which accounts for power capacity at each level of the power distribution hierarchy. It exploits the underutilization of commonly-employed redundant power infrastructure at each level of the hierarchy to safely accommodate a much greater number of servers. Third, CapMaestro exploits stranded power (i.e., power budgets that are not utilized) in redundant power infrastructure to boost the performance of workloads in the data center. We add CapMaestro to a real cloud data center control plane, and demonstrate the effectiveness of all three key features. Using a large-scale data center simulation, we demonstrate that CapMaestro significantly and safely increases the number of servers for existing infrastructure. We also call out other key technical challenges the industry faces in data center power management.
Nonlinear Schrödinger equations with Hardy potential and critical nonlinearities

We study a time-independent nonlinear Schrodinger equation with an attractive inverse square potential and a nonautonomous nonlinearity whose power is the critical Sobolev exponent. The problem shares a strong resemblance with the prescribed scalar curvature problem on the standard sphere. Particular attention is paid to the blow-up possibilities, i.e. the critical points at infinity of the corresponding variational problem. Due to the strong singularity in the potential, some new phenomenon appear. A complete existence result is obtained in dimension 4 using a detailed analysis of the gradient flow lines.
Antibacterial Activities of The Extracts of Mimosa pudica L. An in-vitro Study

Mimosa pudica L . , also called sensitive plant or touch-me-not, belongs to the genus Mimosa (Family: Mimosaceae ). This plant grows as a weed in nearly every parts of Vietnam and is used as a traditional medicine for the treatment of some diseases. This study aims to evaluate the antibacterial activity of the water and ethanol extracts of this plant by using disc diffusion method. The total flavonoid as quercetin equivalent (QE) per gram (dry weight) of these two extracts was also estimated. The result of tests for in-vitro antibacterial activity indicates that the ethanol extract showed significant activity against E.coli, S.aureus, B.subtilis and S.typhi with the zone of inhibition was 11mm, 19mm, 17mm and 16mm respectively. The water extract only inhibited the growth of S.aureus (14mm) and B.subtilis (15mm) and there was no resistance against E.coli and S.typhi . The analysis of total flavonoid content found that the ethanol extract contains higher amount of flavonoid than water extract and flavonoid is responsible mainly for the antibacterial activity of Mimosa pudica L.
Distribution of cadmium in shoot and root tissues of maize and pea plants : physiological disturbances

Maize and pea plants were treated with 0.0 (control), 0.01 or 0.05 mM Cd in the growing medium for 11 d. Although the total Cd concentration was similar in shoot and root tissues of both species, pea plants showed more severe toxic symptoms. The fresh weight and percentage of water content of root and shoot decreased concomitantly to Cd supply. High Cd levels were found in the cell-wall fraction (Fraction I) and in Fraction IV (soluble) of maize plants, whereas Cd-treated pea accumulated more Cd in the soluble fraction. The protein concentration of Fraction IV of pea shoot and root significantly increased upon treatment with 0.05 mM Cd, whereas maize showed no effect. Furthermore, a previously not visible protein (∼12 kDa), appeared in Fraction IV of pea root grown with the highest Cd supply. Cadmium treatment, in general, notably enhanced the concentrations of 2-thiobarbituric acid reactive material (lipid peroxidation products) in pea fractions, presumably due to Cd-induced oxidative stress.
Trade times, importing and exporting: firm-level evidence

This article uses data on 11 industries in 85 developing countries to show that trade times matter for import and export performance at the firm level. Firms import more intermediate inputs if import licensing times are shorter. They export more of their production if border clearance times are shorter, but tend to use third-party distributors more if clearance times are longer. This is the first time that imports and indirect exports have been considered in the firm-level literature on trade facilitation.
Social cognition and the superior temporal sulcus : Implications in autism Cognition sociale et sillon temporal supérieur : implications dans l ’ autisme

The most common clinical sign of autism spectrum disorders (ASD) is social interaction impairment, which is associated with communication deficits and stereotyped behaviors. Based on brain-imaging results, our hypothesis is that abnormalities in the superior temporal sulcus (STS) are highly implicated in ASD. These abnormalities are characterized by decreased grey matter concentration, rest hypoperfusion and abnormal activation during social tasks. STS anatomofunctional anomalies occurring early across brain development could constitute the first step in the cascade of neural dysfunctions underlying autism. It is known that STS is highly implicated on social perception processing, from perception of biological movements, such as body movements or eye gaze, to more complex social cognition processes. Among the impairments that can be described in social perception processing, eye gaze perception is particularly relevant in autism. Gaze abnormalities can now be objectively measured using eye-tracking methodology. In the present work, we will review recent data on STS contributions to normal social cognition and its implication in autism, with particular focus on eye gaze perception. # 2012 Elsevier Masson SAS.
