description: Motivated by the very low diffusivity recently found in ab initio simulations of liquid water, we have studied its dependence with temperature, system size, and duration of the simulations. We use ab initio molecular dynamics (AIMD), following the Born-Oppenheimer forces obtained from density-functional theory (DFT). The linear-scaling capability of our method allows the consideration of larger system sizes (up to 128 molecules in this study), even if the main emphasis of this work is in the time scale. We obtain diffusivities that are substantially lower than the experimental values, in agreement with recent findings using similar methods. A fairly good agreement with D(T) experiments is obtained if the simulation temperature is scaled down by ~20%. It is still an open question whether the deviation is due to the limited accuracy of present density functionals or to quantum fluctuations, but neither technical approximations (basis set, localization for linear scaling) nor the system size (down to 32 molecules) deteriorate the DFT description in an appreciable way. We find that the need for long equilibration times is consequence of the slow process of rearranging the H-bond network (at least 20 ps at AIMD's room temperature). The diffusivity is observed to be very directly linked to network imperfection. This link does not appear an artefact of the simulations, but a genuine property of liquid water.

Distribution
Widespread in the Palaearctic Region (Andersen 1995). In East Asia: Korea (GG, Seoul), China (north-western) (Jorigtoo and Qi 1996), Japan (Hokkaido, Honshu, Shikoku) (Nakajima et al. 2020), Russia (Far East: Primorsky Krai) (Kanyukova 1988).
Biology
Confirmed habitats of M. thermalis in Korea were freshwater bodies, both shaded and unshaded, with abundant emergent and floating vegetation (Fig. 2 C). Observed specimens were mostly found on the floating vegetation during daytime. Some of the confirmed habitats were also occupied by M. vittigera; similar observations were reported by Berchi et al. (2016) in Romania.

description: The overall goal of this research project is to identify and refine factors influencing successful small farm operations in North Carolina. Small farms account for 91 percent of all farms. Given the importance of small farm viability, this research project focuses on identifying ways to further enhance successful small farming in North Carolina. In an effort to further explain the factors that affect successful small-scale farming, researchers have identified factors that have underpinnings in 1) small-farm educational programming; 2) small-scale agricultural enterprises and production practices; 3) alternative marketing; and 4) risk management. Although this research project includes several surveys, for this phase of the project the survey instrument solicited production and financial data, attitudes and beliefs about farming, as well as demographic questions. The research instrument was distributed to a sampling frame that also included small farmers not identified as being successful. Outcomes of this project yielded possible ways to further enhance the success of small farms in North Carolina. Based on case study and questionnaire results, income was not found to be as important as believed and the overall, “love of farming,” seemed to be the driving force behind the farmer’s view of success and not profit. The small farm may represent an individual business enterprise but in reality represents a family business whose success is often measured in qualifiers indicators rather than business quantifiers.

description: Building ventilation ducting systems play a core role in controlling indoor air quality by recirculating the indoor air and mixing with ambient air. The ventilation system can serve as an air cleaning system itself either through the filtration system or integrating other means, while at the same time, attention to energy consumption is needed. The high-efficiency fibrous filters in a conventional filtration system not only cause high-pressure drops that consume fan energy but also add to the high operation cost. This article proposes an air cleaning technique, aimed at submicron particles, by means of installing patterned surfaces on the walls of ventilation ducts, which can be easily cleaned by water and reused. The effect of patterned surfaces on particle deposition was studied numerically. In the numerical simulation, the Reynolds stress turbulent model was correlated at the near-wall regions by turbulent velocity fluctuation at the normal direction. Particle trajectory was solved by using Lagrangian particle tracking. The numerical model was then validated with a particle deposition experiment. A wind tunnel experiment was carried out to quantify the particle deposition on the semicircular micropatterns for a wide range of heights. Based on our numerical results, the semicircular pattern height of 500 µm with a pitch-to-height ratio (p/e) of 10 has 8.58 times enhancement of the energy efficiency compared with a high-efficiency particulate air filter. Our results indicated that adding surface micropatterns to ventilation ducting for submicron particle deposition is a possible energy-efficient air cleaning technique for practical usage.

The intracellular binding partners of Gliotactin
Creators: name: MacKinnon, Christina Marie
Publisher: name: University of British Columbia
Year: 2009

description: Septate Junctions consist of a complex of proteins that establishes and maintains a functional permeability barrier. Gliotactin, a protein required for proper establishment and function of septate junctions, is hypothesized to complex with other septate junction proteins through interactions with its intracellular domain. Two biochemical methods were employed to identify and verify Gliotactin binding partners; a Yeast Two Hybrid Screen and Gliitatione-S-Transferase (GST) Pulldowns. Previous research indicated that Gliotactin interacts genetically with Discs large and can be isolated in a complex with Discs large in co-immunoprecipitation studies. However, GST Pulldown assays showed the two proteins do not directly bind. GST Pulldowns did show that Gliotactin binds with Magi, another PDZ domain containing protein. A Yeast Two Hybrid screen identified a potentially novel interaction with dAif6. dAif6 is found ubiquitously in Drosophila and localizes just below the taenidial folds late in tracheal development. GST Pulldown assays were inconclusive as to whether or not Gliotactin and dAif6 bind directly. However, given that Gliotactin, an essential member of septate junctions, complexes with other members, suggests that Discs large and dArf6 may also be a part of a larger complex of proteins. Further biochemical studies are required to further identify novel members of the complex and Gliotactin binding partners.

description: A new, globally regular model describing a static, non spherical gravitating object in General Relativity is presented. The model is composed by a vacuum Weyl--Levi-Civita special field - the so called gamma metric - generated by a regular static distribution of mass-energy. Standard requirements of physical reasonableness such as, energy, matching and regularity conditions are satisfied. The model is used as a toy in investigating various issues related to the directional behavior of naked singularities in static spacetimes and the blackhole (Schwarschild) limit.

description: A exemplo do que ocorreu no setor urbano, as novas tecnologias da informação aplicadas a agricultura integram-se a rapidamente. Em função disso, nesse artigo foram apresentadas e discutidas algumas tendências da agroinformática focando-se a utilização dos sistemas de informações gerenciais. Como considerações finais percebe-se que estes sistemas irão permear ainda mais as tecnologias da informação através de aplicações em: pacotes de software, ERP agropecuário, rastreabilidade de produtos de origem animal e vegetal, informações climáticas, redes (internet, portais e serviços web); cooperativas, assistência técnica e extensão rural, agricultura de precisão, zootecnia de precisão, e no Ensino a Distância. Embora existam ainda limitações, principalmente por que as tecnologias de informação encontram-se em fase de experimentações nas cadeias produtivas, as demandas existentes quanto ao desenvolvimento de ações junto aos produtores rurais, a criação de grupos de estruturação do conhecimento, a padronização de intercâmbio de informações, o desenvolvimento de parcerias, e a promoção da participação de técnicos brasileiros na definição de padrões de metadados a serem utilizados globalmente, são soluções que poderão concretizar essas tendências. Like what happened in the urban section, the integration of new information technologies applied in the agriculture have been quickly. In function of that, in this paper were presented and discussed some tendencies of information technology applied in the brazzilian agriculture, with the focus on the management information systems. As final considerations, it was perceived that these systems will still permeate the information technologies through applications in: software packages, agricultural ERP, animal and vegetable products traceability, weather information, nets (internet, portals and web services); cooperatives, technical support and rural extension, precision agriculture, precision zoothecnics, and in the Distance Teaching. Although still exist limitations, mainly because information technologies are in phase of experimentations in the productive chains, the existent demands for develop actions close to the farmers, the creation of knowledge structuring groups, the standardization of information exchange, the development of partnerships, and the promotion of brazilian technicians participation in definition of metadatas patterns to be used globally, are solutions that can render those tendencies.

Distribution
Korea (CN), Japan (Hokkaido, Honshu, Izu Islands, Ogasawara Islands, Oki Islands, Shikoku, Kyushu, Nansei Islands) (Hayashi and Miyamoto 2018, Nakajima et al. 2020).
Biology
According to Esaki (1929) and Yuasa (1929), this species dwells on the walls of moist littoral caves where external lights are completely absent. Several distributional records from various localities along the coastline of Japan have been published since, but detailed information on its life history is scarce (cf. Matsuda (2016)).
We collected a number of specimens on the coast of the Yellow Sea, where sandy beaches meet rocky shores and concrete tetrapods (Fig. 2 E). Confirmed habitats were relatively dry and not submerged even in high tides. Large numbers of S. maritima were found actively crawling on the concrete tetrapods and rocks at night. Despite diligent searching, no single individual was found active during the daytime. Taken together, our observations imply that S. maritima could be nocturnal, hiding inside the littoral caves or rocky clefts during the day. In addition, an imbalance in sex ratio was found during the survey: one male amongst 29 females in the first field collection in June and 58 females in the second collection in July. No single nymph was confirmed in both surveys.
Notes
New record for Korea. This species was previously known as a Japanese endemic.

description: Este trabalho analisa a inserção brasileira no mercado internacional de pedras preciosas, um setor de grande importância para o País, embora ainda pouco estudado. A metodologia escolhida consiste no cálculo de alguns indicadores de competitividade internacional, capazes de evidenciar os principais elementos condicionantes do desempenho brasileiro nesse setor. Os resultados encontrados confirmam o potencial do setor, em termos de vantagens comparativas no mercado internacional. Os efeitos observados na decomposição das exportações estão ligados, basicamente, à dinâmica dos principais mercados de destino e também ao crescimento do comércio mundial. Destaca-se, adicionalmente, que apesar da alta informalidade no setor e da falta de informações sistematizadas observa-se recente esforço de reorganização da atividade. Esse movimento, iniciado em instâncias governamentais, visa incentivar o País a participar mais ativamente dos fluxos internacionais de pedras de maior valor agregado, gerando empregos, renda e maior desenvolvimento interno. This work analyzes the Brazilian insertion in the international market of precious stones, which is important to the Country, although it is still little studied. The methodology consists in calculating some indicators to measure the international competitiveness, that are able to indicate the main elements to the development of that Brazilian`s section. The results obtained have confirmed the potential of that section, in terms of comparative advantages at the international market. Decomposition of the exports trend in different components has shown that the exports are linked basically to the main export markets` dynamics, and also to the rate of growth in the world market. Additionally, it can be said that, in spite of the high informality and the lack of systematized information, recent effort has been observed to reorganize the activity. That initiative at the government instances intents to motivate entrepreneurs to participate more actively to the international markets, adding value to their export products, generating new jobs, higher income and internal development.

description: We investigate spin-charge mixing effect on resonant tunneling in spin-polarized Tomonaga-Luttinger liquid with double impurities. The mixing arises from Fermi velocity difference between two spin species due to Zeeman effect. Zero bias conductance is calculated as a function of gate voltage $V_{\rm g}$, gate magnetic field $B_{\rm g}$, temperature and magnetic field applied to the system. Mixing effect is shown to cause rotation of the lattice pattern of the conductance peaks in $(V_{\rm g},B_{\rm g})$ plane, which can be observed in experiments. At low temperatures, the contour shapes are classified into three types, reflecting the fact that effective barrier potential is renormalized towards ``perfect reflection'', ``perfect transmission'' and magnetic field induced ``spin-filtering'', respectively.

description: In past decade, naturally occurring phytoconstituents have emerged as potential therapeutic agents and alternative to synthetic drugs. However, efficient delivery of hydrophobic phytoconstituents into the body with desired therapeutic efficacy is a key challenge for the pharmaceutical industries due to their insolubility in water and low oral bioavailability. Nanosuspension formulations have shown promises to improve the delivery of the hydrophobic molecules with simultaneously avoiding the drawbacks like carrier toxicity and scale-up issues of other nanotechnology-based drug delivery systems. In this study, we have used morin hydrate (MH), a flavonol, and developed MH nanosuspension formulation (MHNS) to improve its poor physiochemical properties and low oral bioavailability. Different stabilizers with varying concentrations were investigated for preparing nanosuspension. MHNS was characterized by DLS, TEM, FTIR, DSC, powder XRD and was evaluated for its solubility, dissolution, partition coefficient, in-vitro anticancer activity and pharmacokinetics in rats. The optimized nanosuspension formulation, with a size of <100 nm, is capable of increasing aqueous solubility, dissolution rate, and oral bioavailability of MH. Moreover, the therapeutic efficacy, in terms of cytotoxicity to human lung cancer cells, of MH was also increased after formulating into nanosuspension form.

description: In this work, we modify the affine wealth model of wealth distributions to examine the effects of nonconstant redistribution on the very wealthy. Previous studies of this model, restricted to flat redistribution schemes, have demonstrated the presence of a phase transition to a partially wealth-condensed state, or "partial oligarchy," at the critical value of an order parameter. These studies have also indicated the presence of an exponential tail in wealth distribution precisely at criticality. Away from criticality, the tail was observed to be Gaussian. In this work, we generalize the flat redistribution within the affine wealth model to allow for an essentially arbitrary redistribution policy. We show that the exponential tail observed near criticality in prior work is, in fact, a special case of a much broader class of critical, slower-than-Gaussian decays that depend sensitively on the corresponding asymptotic behavior of the progressive redistribution model used. We thereby demonstrate that the functional form of the tail of the wealth distribution in a near-critical society is not universal in nature but rather entirely determined by the specifics of public policy decisions. This is significant because most major economies today are observed to be near-critical.

Nos últimos anos, a utilização de inovações tecnológicas e um intenso investimento na melhoria genética do rebanho, das condições de sanidade animal e de manejo levaram o país a atingir importantes marcas de produtividade no setor. Embora problemas recentes enfrentados pelos produtores criem apreensão, a pecuária de corte como um todo não tem o que temer, pois o país está hoje num patamar tecnológico que lhe permite uma certa tranqüilidade. Em razão disso, o presente trabalho investigou e comparou o rendimento produtivo de quatro raças de corte, na região noroeste do Paraná, identificando, na fase de terminação as principais vantagens e desvantagens de cada raça estudada. O trabalho mostrou que a raça nelore apresentou melhores resultados de adaptabilidade, enquanto a canchim mostrou melhor rendimento de carcaça.

Although recent problems faced by the producers create apprehension, the cattle one of cut as a whole does not have what to fear, therefore the country is today in a technological platform that allows a certain tranquillity it. In reason of this, the present work investigated and compared the productive income of four races of cut, in the region the northwest of the Paraná, identifying, in the termination phase the main advantages and disadvantages of each studied race. The work showed that the Nelore race presented better resulted of adaptability, while canchim showed carcass income better.

description: The sensitivity of the nitrogen-vacancy (NV) color centers in diamond-based magnetometers strongly depends on the number of NV centers involved in the measurement. Unfortunately, an increasing concentration of NV centers leads to decreases of their dephasing and coherence time if the nitrogen content exceeds a certain threshold level (approximately ${10^{17}}{\rm{ c}}{\rm{m}^{ - 3}}$). Here, we demonstrate that this increased dephasing can be efficiently compensated by postprocessing procedures in the vicinity of the threshold concertation, thus extending possible useful concentrations on NV centers with the maximum possible decoherence time in diamonds with a natural carbon content.

description: We study $d$-dimensional $AdS$ black holes surrounded by Dark Energy (DE), embedded in $D$-dimensional M-theory/superstring inspired models having $AdS_d \times \mathbb{S}^{d+k}$ space-time with $D=2d+k$. We focus on the thermodynamic Hawking-Page phase transitions of quintessential DE black hole solutions, whose microscopical origin is linked to $N$ coincident $(d-2)$-branes supposed to live in such $(2d+k)$-dimensional models. Interpreting the cosmological constant as the number of colors $\propto N^{\frac{d-1}{2}}$, we calculate various thermodynamical quantities in terms of brane number, entropy and DE contributions. Computing the chemical potential conjugated to the number of colors in the absence of DE, we show that a generic black hole is more stable for a larger number of branes for lower dimensions $d$.In the presence of DE, we find that the DE state parameter $ω_q$ should take particular values, for $(D,d,k)$ models, providing a non trivial phase transition structure.

description: Precision measurements of the Lu$^+$ $^3D_1$ and $^3D_2$ quadrupole moments have been carried out giving $Θ(^3D_1)=0.63862(74)\,e a_0^2$ and $Θ(^3D_2)=0.8602(14)\,e a_0^2$, respectively. The measurements utilize the differential shift between ions in a multi-ion crystal so that effects of external field gradients do not contribute leaving only the well defined Coulomb interaction. At this level of precision, hyperfine-mediated corrections will likely be important.

description: Este estudo teve por objetivo analisar a competitividade das exportações do melão do Rio Grande do Norte no cenário nacional, bem como sua participação e importância para o comércio exterior brasileiro, no período de 1996 a 2005. Utilizou-se os indicadores de desempenho da competitividade das exportações: Vantagens Comparativas Reveladas (VCR) e a Taxa de Cobertura (TC). O Melão, principal fruta exportada pelo Estado do Rio Grande do Norte no período em análise, apresentou substancial incremento na pauta de exportações, chegando a ser o segundo produto mais exportado pelo Estado perdendo apenas para os produtos derivados de Petróleo. Este fato é explicado, basicamente pelos ganhos em competitividade, que foram influenciados por condições internas favoráveis ao desenvolvimento da agricultura irrigada em especial a fruticultura. This study aimed to examine the competitiveness of the exports of melons do Rio Grande do Norte in the national scene, as well as its participation in importance to the Brazilian foreign trade, from 1996 to 2005. It was used indicators of performance of the competitiveness of exports: comparative advantages Reveladas (VCR) and the rate of coverage (CT). The Melon, the main fruit exported by the State of Rio Grande do Norte in the period under review, showed substantial increase in tariff for exports, reaching be the second most product exported by the State losing only for products derived from oil. This fact is explained basically by gains in competitiveness, which were influenced by internal conditions for the development of irrigated agriculture in particular Fruits.

description: A model of the negotiation process is developed and applied to a sample of negotiation cases through qualitative meta-analysis. Key findings revealed a two-dimensional matrix comprising the entire negotiation process, and suggest that value creation strategies should be used for both parties in such transactions to achieve mutual benefits. This article is intended to provide scholars with a new perspective and taxonomy on the negotiation dimensions, and implications of these findings for managerial practice are discussed.

description: We have obtained deep near-infrared images in J and K filters of three fields in the Sculptor galaxy NGC 300 with the ESO VLT and ISAAC camera. For 16 Cepheid variables in these fields, we have determined J and K magnitudes at two different epochs, and have derived their mean magnitudes in these bands. The slopes of the resulting period-luminosity relations are in very good agreement with the slopes of these relations measured in the LMC by Persson et al. Fitting the LMC slopes to our data, we have derived distance moduli in J and K. Using these values together with the values derived in the optical V and I bands in our previous work, we have determined an improved total reddening for NGC 300 of E(B-V)=0.096 +/- 0.006 mag, which yields extremely consistent values for the absorption-corrected distance modulus of the galaxy from VIJK bands. Our distance result for NGC 300 from this combined optical/near infrared Cepheid study is (m-M)_0 = 26.37 +/- 0.04 (random) +/- 0.03 (systematic) mag and is tied to an adopted true LMC distance modulus of 18.50 mag. Both random and systematic uncertainties are dominated by photometric errors, while errors due to reddening, metallicity effects and crowding are less important. Our distance determination is consistent with the earlier result from near-infrared (H-band) photometry of two Cepheids in NGC 300 by Madore et al., but far more accurate. Our distance value also agrees with the HST Key Project result of Freedman et al., and with the recent distance estimate for NGC 300 from Butler et al. from the TRGB I-band magnitude when our improved reddening is used to calculate the absorption corrections. Our distance results from the different optical and near-infrared bands indicate that the reddening law in NGC 300 must be very similar to the Galactic one.

description: Este texto pretende comparar as políticas de o incentivo à produção de etanol e biodiesel no Brasil e no mundo, mostrando como este último pode evitar os erros recorrentes do primeiro e permitir um desenvolvimento econômico e social mais eqüitativo. Ressalta-se que o etanol teve uma trajetória baseada na grande escala e nos ganhos de produtividade, mas não deu atenção a questões como as de desenvolvimento econômico e social no âmbito regional. O Programa Nacional de Biodiesel tem a preocupação com o fornecimento de matérias-primas a partir da agricultura familiar, mas dá pouca atenção a questões como o uso local do biodiesel para geração de energia, algo que está na pauta de políticas regionais e locais que estão começando a serem implementadas. This text intends to compare the politics of the incentive with the production of etanol and biodiesel in Brazil and the world, being shown as this last one can prevent the recurrent errors of the first one and allow more equitable a economic and social development. It is standed out that etanol had a trajectory based on the great scale and the profits of productivity, but did not give to attention the questions as of economic and social development in the regional scope. The National Program of Biodiesel has the concern with the supply of raw materials from familiar agriculture, but of the little attention the questions as the local use of biodiesel for generation of energy, something that is in the guideline of regional politics and local that is starting to be implemented.

description: The parkerite-type ternary chalcogenide Bi$_2$Rh$_3$Se$_2$ was discovered to be a charge density wave (CDW) superconductor. However, there was a debate on whether the observed phase transition at 240 K could be attributed to the formation of CDW order. To address the issue, we performed optical spectroscopy and ultrafast pump-probe measurements on single crystal samples of Bi$_2$Rh$_3$Se$_2$. Our optical conductivity measurement reveals clearly the formation of an energy gap with associated spectral change only at low energies, yielding strong evidence for a CDW phase transition at 240 K. Time resolved pump-probe measurement provides further support for the CDW phase transition. The amplitude and relaxation time of quasiparticles extracted from the photoinduced reflectivity show strong enhancement near transition temperature, yielding further evidence for the CDW energy gap formation. Additionally, a collective mode is identified from the oscillations in the pump-probe time delay at low temperature. This mode, whose frequency decreases gradually at elevated temperature, could be naturally attributed to the amplitude mode of CDW state.

The reality of print literature resources in a representative sample of urban child care centres

Publisher: name: University of British Columbia

description: This thesis is a qualitative study of six full day childcare centres. The purpose of this study was to identify the print literature resources that are present within a representative sample of urban childcare centres. Data were collected using field notes and manager interviews. A further analysis of the resources present allowed to the researcher to evaluate the quality of the resources and to discern whether the early childhood educators sampled have the resources to provide the foundation for a quality literature program. The books were analysed using five elements, including; literary merit, age and accuracy, physical condition, genre and developmental appropriateness, and quantity and accessibility. A total of 2774 resources were present in the six childcare centres. Overall the centres did not satisfy the elements for quality resources. Only 1% of the resources were found to have been judged worthy of recognition through nomination or award. The average age of the resources was 16 years, with an age span of 102 years, causing concern for accuracy, especially for information literature. The physical condition of the print literature resources did conform to quality guidelines, and it was discovered that physical condition was the only reason for discarding a book. There were a variety of genres present within the childcare centres, with the largest genre being information books. The second largest genre was surprising, as TV/Toy books represented 19.5% of the total collections. None of the centres met International Reading Association guidelines for quantity or accessibility for classroom libraries. It was clear that quantity and cost were the most important factors influencing the print literature collections in these childcare centres.

description: Who should be charged with responsibility for an artificial intelligence performing market manipulation have been discussed. In this study, I constructed an artificial intelligence using a genetic algorithm that learns in an artificial market simulation, and investigated whether the artificial intelligence discovers market manipulation through learning with an artificial market simulation despite a builder of artificial intelligence has no intention of market manipulation. As a result, the artificial intelligence discovered market manipulation as an optimal investment strategy. This result suggests necessity of regulation, such as obligating builders of artificial intelligence to prevent artificial intelligence from performing market manipulation.

description: The possibility to observe the medium-modified fragmentation of hard b-quarks tagged by a leading muon in ultrarelativistic heavy ion collisions is analyzed. We have found that reasonable statistics, ~20000 events per 1 month of LHC run with lead beams, can be expected for the realistic geometrical acceptance and kinematic cuts. The numerical estimates on the effect of the medium-induced softening b-jet fragmentation function are given.
