Heterotrophic nitrification and aerobic denitrification by four novel isolated bacteria

Heterotrophic nitrifying bacteria are attracting increasing interest due to their advantages in treatment of wastewater with high nitrogen concentration. In this work, four bacterial isolates (WS-1, WS-4, WS-6, and WS-7) with the capability of simultaneous heterotrophic nitrification and aerobic denitrification from soil, sludge, and water by a fast isolation procedure were studied. Isolates WS-1, WS-6, and WS-7 were identified as Pseudomonas sp. and WS-4 as Agrobacterium sp. based on 16S rRNA gene sequence analysis. All four isolates could utilize ammonia, nitrate, and nitrite as sole nitrogen source and the metabolic characteristics were shown to be related with the genus. In addition, Agrobacterium sp. WS-4 accumulated less nitrate than the three Pseudomonas sp. strains with ammonia as the sole nitrogen source. When nitrate or nitrite was the sole nitrogen source, Agrobacterium sp. did not produce ammonia, and it consumed the least nitrogen compared with the three Pseudomonas sp. isolates. Our studies implied that Pseudomonas sp. strains had great potential in treating high nitrogen in wastewater.
Micromachined ridge gap waveguide for sub millimeter and millimeter wave applications

High-frequency waveguide technology has become a field of great interest lately. In this paper we present a ridge gap waveguide with two 90 degree bends and a ridge gap waveguide resonator, both fabricated with MEMS technology. It is the first time the ridge gap waveguides have been fabricated for millimeter waves. The ridge gap waveguides is realized of two conducting plates, one of them with a texture, and can provide low transmission losses without any requirements to alignment between the two plates, and with neither conductive joints nor sidewalls. The Ridge gap waveguide makes use of a ”bed of nails” structure which acts as a magnetic conductor and creates a cut-off for parallel plate modes between the two plates. Thereby, wave propagation is confined to the electric conducting ridge, without making use of electrically conducting sidewalls. MEMS technology can provide precision machining which makes it possible to go up in higher frequency bands than with conventional machining. The purpose of this paper is to describe the the fabrication process of the surface textured with pins and ridge.
Supplementation of ewes on pasture to provide an epidemiological benefit for gastrointestinal parasitism.

The potential epidemiological benefit of reducing the peri-parturient relaxation in immunity to gastro-intestinal nematode parasites through supplementing twin-bearing ewes during the first four weeks of lactation was evaluated in a replicated farmlet study. In two sequential years, ewes either grazed pasture alone or grazed pasture while supplemented with 0.5 kgDM/d of a high-protein pellet. Supplementation did not affect ewe live weight or body condition score or weight of lamb weaned per ewe (P>0.05). Ewe faecal egg counts (FEC) showed a time x supplementation interaction (P<0.05), being reduced by 50% from week six of lactation in both years, although this only resulted in transient and inconsistent reductions in pasture larval contamination. After weaning, there was no consistent parasitological benefit to lambs grazing areas where ewes had been supplemented that were reflected in either pasture larvae concentrations, lamb FEC, the requirement for anthelmintic treatment or lamb growth rate (P>0.05 for all). Despite supplementation of ewes during the first four weeks of lactation successfully reducing ewe faecal egg count by 50%, this was not sufficient to provide a measureable and consistent epidemiological benefit to the lambs.
Vision/Odometer Autonomous Navigation Based on RatSLAM for Land Vehicles

This paper discusses the design of computer vision and odometer integrated autonomous navigation algorithm based on RatSLAM system for land vehicles. The research aims at testing the effectiveness of a vision/odometer bio-inspired navigation approach for land vehicle applications. Images and odometer measurements are inputted into the RatSLAM system. Odometer data can be used to improve the robustness of RatSLAM system significantly. The proposed system has been verified on real vision/odometer data collected in land vehicle tests. Campus round road experiments illustrate that the algorithm is effective and robust.
On the marginal deformations of general (0,2) non-linear sigma-models

In this note we explore the possible marginal deformations of general (0,2) non-linear sigma-models, which arise as descriptions of the weakly-coupled (large radius) limits of four-dimensional $\mathcal{N}= 1$ compactifications of the heterotic string, to lowest order in $\alpha'$ and first order in conformal perturbation theory. The results shed light from the world-sheet perspective on the classical moduli space of such compactifications. This is a contribution to the proceedings of String-Math 2012.
Correction for clipping of Doppler spectra from clouds and other atmospheric targets

Computing a Doppler spectrum usually increases the radar signal to noise ratio (SNR) considerably. The noise is distributed over all Doppler cells and the signal from atmospheric targets is concentrated in a limited interval. Storing the entire Doppler spectrum is often not done to reduce data storage, instead the moments of the Doppler spectrum are computed: total power, average velocity and Doppler width. One way to prevent the signal to be drowned in noise again, when calculating the moments, is to apply clipping or thresholding. Clipping simply means ignoring Doppler cells that have a power close to the noise level per Doppler cell. A picture showing the idea of clipping is presented. Clipping is very effective in removing noise, however a drawback is that also some signal is removed. If the clip level is close to the peak power in some Doppler cell, most of the signal power will even be removed. The width of the Doppler spectra is even stronger affected. If the distribution is not symmetrical, also the average velocity will change due to clipping. The effect of clipping is studied on radar cloud measurements made with the Delft Atmospheric Research Radar, Darr. This is a sensitive 9-cm radar with a high Doppler resolution of 3.5 cm/s. Normally 256 Doppler cells make up one Doppler spectrum. This spectrum is clipped at 7 dB above the noise per Doppler cell. The Doppler width (standard deviation) for the clouds in this study is between 18 and 30 cm/s. When an accurate quantitative value for the signal power is needed the calculated average power must be corrected for the effect of clipping. To derive a function for the correction of the measured total power, the data processing of a Doppler radar has been simulated using a known signal.
The Effect of Special Exercises for the Development of Performance Endurance Ability and Correlation it with Accuracy Scoring from Jumping in Basketball

The objective of the research was to identify the effect of the special exercises in the research in developing the ability to withstand the performance of the basketball as well as to identify the relationship between the performance and accuracy of the scoring of jumping basketball. The researcher used the experimental method for his research problem. The research sample was chosen in a deliberate way. They are (22) players who are divided into two equal groups (10) players for the experimental group and (10) players for the control group and a percentage of (90%) from the original search community where players were excluded for the purpose of the exploratory experiment. After the main experiment and tests were completed, the (SPSS) program was used for statistical data processors to reach the results, after which the results were presented and discussed. The results of the study showed that there were statistically significant differences between the post tests of the two groups in the basketball endurance test and for the benefit of the group. The results showed that there is a correlation between the ability to withstand performance and the accuracy of the scoring of basketball jump as the increase in working periods affect the concentration and thus reduce accuracy. The researcher recommended the use of special exercises according to the skill requirements to be developed in order to reach the required level. He also recommended the need to develop the ability to withstand the performance of the players because they are closely related to the accuracy of the scoring. And recording when the basketball. Keywords: Special exercises, Performance endurance, Ability, Accuracy and jumping.
Private Returns to Education in Pakistan: A Statistical Investigation

The paper statistically evaluates the trends in private returns to education in Pakistan for the period 1990-91 to 2012-13. The data of 16 nationally representative Labor Force Surveys during this period are utilized to estimate the standard Mincerian Earning Functions with some modifications. Trends are also disaggregated for gender, region, province, sectors and educational attainments. In addition, the study also employs the pseudo-panel approach for the first time in Pakistan for estimating overall returns to education to control unobserved individual heterogeneity which is common to estimate returns from data on individuals. The estimate using the traditional approach with individual LFS cross-section data suggests 5.5 percent yearly returns for wage earners after controlling for the heterogeneity in the regional and provincial labor markets in Pakistan. Nonetheless, the study found considerably larger returns to education from the pseudo-panels with year fixed effects. The estimates of earning equation with birth specific cohort data reveal about 9.2 percent returns for overall Pakistani labor market.
Amino acid geochronology of individual foraminifer (Pulleniatina obliquiloculata) tests, north Queensland margin, Australia: A new approach to correlating and dating Quaternary tropical marine sediment cores

[1] In this study, we demonstrate the utility of amino acid geochronology based on single-foraminiferal tests in Quaternary sediment cores from the Queensland margin, Australia. The large planktonic foraminifer Pulleniatina obliquiloculata is ubiquitous in shelf, slope, and basin sediments of north Queensland as well as pantropical oceans. Fossil tests are resistant to dissolution, and retain substantial concentrations of amino acids (2–4 nmol mg � 1 of shell) over hundreds of thousands of years. Amino acid D and L isomers of aspartic acid (Asp) and glutamic acid (Glu) were separated using reverse phase chromatography, which is sensitive enough to analyze individual foraminifera tests. In all, 462 Pulleniatina tests from 80 horizons in 11 cores exhibit a systematic increase in D/L ratios down core. D/L ratios were determined in 32 samples whose ages are known from AMS 14 C analyses. In all cases, the Asp and Glu D/L ratios are concordant with 14 C age. D/L ratios of equal-age samples are slightly lower for cores taken from deeper water sites, reflecting the sensitivity of the rate of racemization to bottom water temperature. Beyond the range of 14 C dating, previously identified marine oxygen-isotope stage boundaries provide approximate ages of the sediments up to about 500,000 years. For this longer time frame, D/L ratios also vary systematically with isotope-correlated ages. The rate of racemization for Glu and Asp was modeled using power functions. These equations can be used to estimate ages of samples from the Queensland margin extending back at least 500,000 years. This analytical approach provides new opportunities for geochronological control necessary to understand fundamental sedimentary processes affecting a wide range of marine environments.

Characteristics of gas-flux density distribution at the water surfaces

Numerical simulation of a wind-driven turbulent flow underneath a wavy surface is conducted to characterize the distribution of gas-flux density across the water surface, and to explore the potential correlation between the gasflux density and other surface quantities, including the temperature, the wave slope and the velocity divergence. It is found that the underlying elongated streamwise eddies, which are either associated with the coherent vortical flows within the turbulent boundary layer or formed from the nonlinear interaction between the drift current and the surface waves, contribute to the major transfer rate at the water surface. These longitudinal eddies induce streaky thermal signature at the water surface, which is found to highly correlate with the gasflux density.
Do Women Give Up Competing More Easily? Evidence from the Lab and the Dutch Math Olympiad

We use lab experiments and field data from the Dutch Math Olympiad to show that women are more likely than men to stop competing if they lose. In a math competition in the lab, women are much less likely than men to choose competition again after losing in the first round. In the Math Olympiad, girls, but not boys, who fail to make the second round are less likely to compete again one year later. This gender difference in the reaction to competition outcomes may help to explain why fewer women make it to the top in business and academia. (JEL C90, D82, D91, J16)

Nonlinearity, liquefaction, and velocity variation of soft soil layers in Port Island, Kobe, during the Hyogo-ken Nanbu earthquake

Clear nonlinear behavior is analyzed from the acceleration records of the 1995 Hyogo-ken Nanbu earthquake at Port Island, Kobe. From four triaxial instruments placed at four different depths, the surficial effects during strong ground motions were compared with those during weak motions before and after the mainshock. We used a spectral ratio technique and a nonlinear inversion for velocity structure to analyze the data. From the spectral analysis, we observed a large variation of the spectral ratios between the surface and different depths during the strong ground motions and during the liquefied state. The spectral ratios after the mainshock (i.e., after the liquefied state) are different from those before the mainshock. The peak frequencies in the spectral ratios after the mainshock are shifted to lower frequencies with respect to those in the spectral ratios before the mainshock. We inverted the S-wave velocities using a genetic algorithm technique to determine the velocity structure before, during, and after the mainshock. The S-wave velocity structure before and after the mainshock was found to be different. Specifically, the S-wave velocity of the second layer (5 m to 16 m depth) after the mainshock was 20% lower than before. Our analysis shows that the liquefied state remains at least 3 hr after the mainshock but no more than 24 hr. The rigidity of the soil decreased close to zero when liquefaction happened and later increases gradually following a trend that resembles a consolidation curve. The strong influence of nonlinearity during the mainshock yielded a big reduction of the horizontal surface ground motions, so that the observed horizontal peak acceleration was only about 25% of the peak acceleration expected from the linear theory. However, the nonlinear effects in the vertical peak acceleration were not significant.
Journal of Research and Didactics in Geography (J-READING), 2, 3, Dec

The Australian rural landscape has been changing throughout history since the first European settlement. The progressive expansion of agriculture in the past centuries is responsible for its modification and diversification. Family farming has a relevant role in the Australian agriculture and food production, however in the last decades it has been facing a consistent decline, primarily because of economic and climatic reasons. This paper aims to retrace the historical development of agriculture in Australia and to analyse the current situation of family farming, by reporting the tendencies and the changed features, the educational and social aspects, and the interaction with the rural landscape. According to our research it emerged that family farming has been one of the major keys of the agricultural sector development in Australia and was deeply affected through history by internal and external factors such as globalization, neoliberalism, immigration and climatic conditions. Nowadays family farming is pivotal in the interface connection between modern societies and rural environment. In fact it is also becoming an important component of national tourism, with the birth and development of agrotourisms and holiday farms which in the past years have accounted for a considerable percentage of visits both from international and national people.
Identification and Analysis of Entrepreneurial Strategies preserving Schumpeterian Rent

Purpose- As any increase in the price of resources and any imitation by competitors decrease entre-preneurial rent, the entrepreneurs should use some kind of strategies to preserve this rent. We used resource based view as a lens for finding these strategies. Design/methodology/approach- For conducting this research, qualitative method was used and qual-itative research questionnaire was formed based on Peteraf model, 15 entrepreneurial companies have participated for completing this study. Findings A total of 13 strategies have been identified and analyzed which are: Pioneering strategy, Economy of Scale, Establishing reputation and brand, Creating continuous innovation, Secrecy and ambiguity strategy, Franchise development, Control of resources, Legal barriers, Compromise with competitors, Selecting strategic location for business, Sharing profit with resource owners, Supplier diversification and Vertical integration. Research Implications- Entrepreneurs can use these strategies to preserve their rent. In addition, the researchers can use these results for further research and developing the literature of entrepreneurial strategies which was not rich before presenting this research. Originality/value- This is the first qualitative research which tries to identify entrepreneurial strate-gies through the resource-based view lens. Furthermore the research tries to differentiate entrepre-neurial strategies from non-entrepreneurial strategies for the first time.

Numerical solution and stability analysis of a nonlinear vaccination model with historical effects

In this paper, we extend the classical vaccination epidemic model from a deterministic framework to a model with historical effects by formulating it as a system of fractional-order differential equations (FDEs). The basic reproduction number $R_0$ of the resulting fractional model is computed and it is shown that if $R_0$ is less than one, the disease-free equilibrium is locally asymptotically stable. Particularly, we analytically calculate a certain threshold-value for $R_0$ and present the existence conditions of endemic equilibrium. By using stability analysis, we prove stability and $\alpha$-stability of the endemic equilibrium points. The proposed model is applied on \emph{Pertussis} disease and the fractional nonlinear system of the model is solved by applying multi-step generalized differential transform method (MSGDTM). Our results show that historical effects play an important role on the disease spreading.

Probabilistic Virtual Machine Assignment

We cast the assignment of virtual machines (VMs) to physical servers as a variant of the classic bin packing problem. We then develop a model of VM load that can be used to produce assignments of VMs to servers. Using this problem formulation and model, we evaluate heuristic solutions to this problem. We evaluate the performance of these solutions in stochastic load environments. We verify the model proposed and show that it can be adapted to respond well to varying VM loads.
