description: We study the diffusive behavior of chiral active (self-propelled) Brownian particles in a two-dimensional microchannel with a Poiseuille flow. Using numerical simulations, we show that the behavior of the transport coefficients of particles, for example, the average velocity $v$ and the effective diffusion coefficient $D_{eff}$, strongly depends on flow strength $u_0$, translational diffusion constant $D_0$, rotational diffusion rate $D_θ$, and chirality of the active particles $Ω$. It is demonstrated that the particles can exhibit upstream drift, resulting in a negative $v$, for the optimal parameter values of $u_0$, $D_θ$, and $Ω$. Interestingly, the direction of $v$ can be controlled by tuning these parameters. We observe that for some optimal values of $u_0$ and $Ω$, the chiral particles aggregate near a channel wall, and the corresponding $D_{eff}$ is enhanced. However, for the nonchiral particles ($Ω= 0$), the $D_{eff}$ is suppressed by the presence of Poiseuille flow. It is expected that these findings have a great potential for developing microfluidic and lab-on-a-chip devices for separating the active particles.

description: The essential oils (EOs) of Rosmarinus officinalis (Ro) are from two cities located in the eastern region of Morocco (Taourirt and Jerrada) were extracted using the steam distillation method in two cooperatives, namely "Belahssan" and "Beni Yaala Zkara", respectively. The chemical composition was determined by gas chromatography coupled with mass spectrometry (GC/MS), in which 1,8-cineole (53.6%), α-pinene (12.3%), and camphor (9.6%) represented the major compounds for essential oil of Rosmarinus officinalis from Taourirt (RoEOT). While, 1,8-cineole (42.3%), α-pinene (11.6%), and camphor (10.5%) were predominant in that of Jerada Rosmarinus officinalis (RoEOJ). The antioxidant activity of the two essential oils was assessed using, the free radical scavenging activity against the DPPH•, the ferric reducing power assay (FRAP), and the β-carotene bleaching technique.
title: The Supply of National Park Products: A Theoretical and Applied Analysis
Creators: name: Houston, Judith Carol
Publisher: name: Utah State University
Year: 1976

description: The central objective of the investigation in this study is to determine a means of attaining an economically efficient combination of resources to maximize the level of services provided by a national park under the conditions of a limited budget, a constrained production possibilities set, and a limited availability of inputs. First, a theoretical model is built which elucidates the collective and private good natures of national park products. The theory identifies the optimality criteria for the provision of park products in a system of limited resources. It is noted, however, that the theoretically determined optimal solution cannot be expected to emerge automatically in a market situation due to the social good nature of some park products. Therefore, a second-best objective of maximizing the value of the park's output as evaluated by the park's superintendent is adopted for use in the study's applied analysis.
The empirical model which is then constructed, combines concepts from economic theory and mathematical programming which lend themselves to solving the production economizing problems facing a park. It offers national park managers operational tools for aiding in their decision-making. While the paper points to important implications for current policy, it also indicates promising directions for future study.

This is a property that encompasses both the doubling measures and those satisfying the upper power bound μ(B(x,r)) \le Cr^d. Our spaces are only assumed to satisfy the geometric doubling property: every ball of radius r can be covered by at most N balls of radius r/2. A key ingredient is the construction of random systems of dyadic cubes in such spaces.

Enamasti on kirjeldatud üksikuid juhtumeid, aga ka kuni 20 haigusjuhu ülevaateid (4–6). Igal juhul on otstarbekas teha skalbi replantatsioonikatse (7, 8). Samas tuleb siinkohal arvesse võtta nii trauma mehhanismi, skalbi terviklikkust ja kontaminatsiooni ulatust, transplantaadi isheemia aega kui ka adekvaatseid säilitamise ja transportimise tingimusi.

description: The magnetic H - T phase diagram of a quasi-two-dimensional easy plane antiferromagnet RbFe(MoO$_4$)$_2$ (S = 5/2) with an equilateral triangular lattice structure is studied with $^{87}$Rb NMR technique for field directed along hard axis C3. The studies confirm the two step transition from the low field umbrella-like incommensurate magnetic phase to the paramagnetic state observed recently (Mitamura et al. 2016). The transitions were identified as a lambda anomaly in the spin-lattice relaxation rate and a step increase of magnetic susceptibility at intermediate transition. The $^{87}$Rb NMR study precludes the possibility of either V or fan spin textures in the X phase. The additional transition is presumably associated with loss of inter plane magnetic order before the transition to paramagnetic state of individual triangular planes.

description: We report the detection of Voigt spectral line profiles of radio recombination lines (RRLs) toward Sagittarius B2(N) with the 100-m Green Bank Telescope (GBT). At radio wavelengths, astronomical spectra are highly populated with RRLs, which serve as ideal probes of the physical conditions in molecular cloud complexes. An analysis of the Hn(alpha) lines presented herein shows that RRLs of higher principal quantum number (n>90) are generally divergent from their expected Gaussian profiles and, moreover, are well described by their respective Voigt profiles. This is in agreement with the theory that spectral lines experience pressure broadening as a result of electron collisions at lower radio frequencies. Given the inherent technical difficulties regarding the detection and profiling of true RRL wing spans and shapes, it is crucial that the observing instrumentation produce flat baselines as well as high sensitivity, high resolution data. The GBT has demonstrated its capabilities regarding all of these aspects, and we believe that future observations of RRL emission via the GBT will be crucial towards advancing our knowledge of the larger-scale extended structures of ionized gas in the interstellar medium (ISM).
title: Nitrogen Fertilization Studies in Dryland Winter Wheat and Potential Nitrogen Losses from the Soil at the Blue Creek Experimental Station in Northern Utah
Creators: name: Intalop, Subhawat
Publisher: name: Utah State University
Year: 1976

description: This study compared the effects of nitrogen sources on the available inorganic soil nitrogen, nitrogen movement, nitrogen losses, and wheat yields when nitrogen fertilizers were applied to soil planted to dryland winter wheat at the Blue Creek Experimental Station in northern Utah.
In the fall 1973 soil samplings, the fertilizers producing the largest mineral nitrogen contents in the 0-30 cm soil depths were ammonium nitrate > ammonium sulfate > S-coated urea, when they were broadcast at the practical rate of 56 kg N/ha. There was no increase in the mineral nitrogen at the deeper depths in the fall or at any depth in the following spring. Statistically, the three nitrogen sources did not increase grain yield significantly but did increase grain protein content and nitrogen content in grain.
Ammonium nitrate and potassium bromide at the rates of 400 kg N and 200 kg Br/ha were broadcast to soil planted to winter wheat in October 1974. Nitrate-nitrogen and bromide distribution patterns in the soil profile looked alike in May 1975. These showed that their movements were similar. Considerable nitrate-nitrogen (35 percent of the added nitrogen) had moved down below the 120 em depth. The highest nitrate-nitrogen concentrations were found at the 45 to 90 cm depth. There seems to be evidence that nitrate-nitrogen and bromide had moved deeper than the 150 cm depth.
Ammonia- nitrogen losses from nitrogen fertilized soils were conducted in the laboratory. Ammonium sulfate, ammonium nitrate, or urea applied to the soil surface lost ammonia-nitrogen differently. From noncalcareous soil, the ammonia-nitrogen loss was greatest from urea. From calcareous soil or soils receiving carbonates or high soil pH by the addition of sodium hydroxide solution, the greatest losses were from ammonium sulfate. High losses were favored by high temperatures and longer periods of moist soil. The total amounts of water lost from the soil was not closely related to the total ammonia-nitrogen loss during two weeks. No loss of ammonia-nitrogen occurred when nitrogen fertilizers were applied at a 2.5 cm depth or deeper. The ammonia-nitrogen losses were also greatly reduced when nitrogen fertilizers applied to the soil surface was followed by irrigation or heavy rainfall.
In the field, the higher temperatures increased the ammonia-nitrogen losses from ammonium sulfate, ammonium nitrate, and urea when applied to both a noncalcareous and a calcareous soil. However, the loss from calcareous soil was reduced by irrigation following fertilizer application. No ammonia-nitrogen was observed when ammonium sulfate was applied at a 2. 5 cm soil depth, despite of the high soil temperature during the day time in moist soil. Rapid drying of the moist soil surface quickly reduced the losses per day.

description: The phytochemical study on the stems and leaves of Morinda citrifolia L. resulted in the isolation of a new naturally occurring bisabolane-type sesquiterpenoid, morincitrinoid A (1), together with five known analogues (2–6). The chemical structure of 1 was elucidated by comprehensive spectral analyses. The known compounds 2–6 were identified by comparing their spectral data with those reported in the literature, which were isolated from M. citrifolia for the first time. In addition, the anti-inflammatory and anti-HIV activities of compounds 1–6 were evaluated in vitro. Compounds 1–6 displayed significant inhibitory activities on NO (nitric oxide) production induced by lipopolysaccharide in mouse macrophage RAW 264.7 cells with IC50 values ranging from 0.98 ± 0.07 to 6.32 ± 0.11 μM, which was comparable to hydrocortisone. Meanwhile, compounds 1–6 showed remarkable anti-HIV-1 reverse transcriptase (RT) effects with the EC50 values ranging from 0.16 to 6.29 μM.

description: Current quality standards and nutrition recommendations are not specific for older adults in residential aged care homes. This research explored oral intake and solutions to using a 'food first' approach to maximise energy and protein intake and reduce unintentional weight loss Key findings identified that food volume and therefore nutritional intake is insufficient, and national nutrition recommendations for serving sizes are too large for residents to consume. Fortified diets and re-shaped texture modified foods increase energy and protein provision and consumption. These evidence-based findings will inform nutrition in residential aged care into the future.

description: In the present work, we investigate the magnetic properties of ferrimagnetic and noninteracting maghemite (g-Fe2O3) hollow nanoparticles obtained by the Kirkendall effect. From the experimental characterization of their magnetic behavior, we find that polycrystalline hollow maghemite nanoparticles are characterized by low superparamagnetic-to-ferromagnetic transition temperatures, small magnetic moments, significant coercivities and irreversibility fields, and no magnetic saturation on external magnetic fields up to 5 T. These results are interpreted in terms of the microstructural parameters characterizing the maghemite shells by means of an atomistic Monte Carlo simulation of an individual spherical shell model. The model comprises strongly interacting crystallographic domains arranged in a spherical shell with random orientations and anisotropy axis. The Monte Carlo simulation allows discernment between the influence of the structure polycrystalline and its hollow geometry, while revealing the magnetic domain arrangement in the different temperature regimes.

description: The mountainous ranges of the West are commonly used during the summer and have been used in this manner since the settlement of white men over a century ago. Many of these ranges have been mis-managed and are in poor condition. The productivity of these ranges greatly affects the economy of the nation; thus, if ranges in poor condition have a nutritive value lower than ranges in good condition, it results in an economic loss. little work has been done to determine the nutritive value of mountainous summer ranges in good condition compared to similar ranges in poor condition.
Implementation of higher-order absorbing boundary conditions for the Einstein equations

description: We present an implementation of absorbing boundary conditions for the Einstein equations based on the recent work of Buchman and Sarbach. In this paper, we assume that spacetime may be linearized about Minkowski space close to the outer boundary, which is taken to be a coordinate sphere. We reformulate the boundary conditions as conditions on the gauge-invariant Regge-Wheeler-Zerilli scalars. Higher-order radial derivatives are eliminated by rewriting the boundary conditions as a system of ODEs for a set of auxiliary variables intrinsic to the boundary. From these we construct boundary data for a set of well-posed constraint-preserving boundary conditions for the Einstein equations in a first-order generalized harmonic formulation. This construction has direct applications to outer boundary conditions in simulations of isolated systems (e.g., binary black holes) as well as to the problem of Cauchy-perturbative matching. As a test problem for our numerical implementation, we consider linearized multipolar gravitational waves in TT gauge, with angular momentum numbers l=2 (Teukolsky waves), 3 and 4. We demonstrate that the perfectly absorbing boundary condition B_L of order L=l yields no spurious reflections to linear order in perturbation theory. This is in contrast to the lower-order absorbing boundary conditions B_L with L

description: Cashew (Anacardium occidentale L.) leaf is traditionally used to treat skin infections. Although many flavonols have been identified from its leaf extract, their inhibitory effects on skin pathogens are not yet determined. The aims of this study were to determine the antimicrobial (against skin pathogenic microbes) and antioxidant activities of four flavonol glycosides from the crude extract and three flavonol aglycones from the hydrolyzed extract. The hydrolyzed extract was found to show higher activities than the crude extract. Myricetin showed the highest activity against all the tested bacteria and yeast with the lowest Minimum Inhibition Concentration (MIC) of 7.81 μg/mL on Corynebacterium minutissimum ATCC23348. Myricetin also exhibited good primary antioxidant activities with the effective concentration with 50% of activity (EC50) values ranged between 2.23 μg/mL and 6.40 μg/mL. The highest secondary antioxidant activity was indicated by myricetin-3-O-rhamnoside. Thus, myricetin can be considered as a bioactive compound of the hydrolyzed extract.

description: Software-intensive systems produce logs for troubleshooting purposes. Recently, many deep learning models have been proposed to automatically detect system anomalies based on log data. These models typically claim very high detection accuracy. For example, most models report an F-measure greater than 0.9 on the commonly-used HDFS dataset. To achieve a profound understanding of how far we are from solving the problem of log-based anomaly detection, in this paper, we conduct an in-depth analysis of five state-of-the-art deep learning-based models for detecting system anomalies on four public log datasets. Our experiments focus on several aspects of model evaluation, including training data selection, data grouping, class distribution, data noise, and early detection ability. Our results point out that all these aspects have significant impact on the evaluation, and that all the studied models do not always work well. The problem of log-based anomaly detection has not been solved yet. Based on our findings, we also suggest possible future work.

Understanding the biological response to weight loss: An individual perspective

Publisher: name: Monash University
Year: 2022

description: Obesity is a global issue with rates increasing worldwide. Weight loss interventions tailored to an individual’s biology may provide improved health outcomes over traditional ‘one size fits all’ strategies. Understanding an individual’s response to weight loss is fundamental to addressing this. This Thesis has demonstrated that individual responses to weight loss interventions are highly variable. In both adults and adolescents, variation within outcomes were observed between individuals including location of weight lost and gene expression. These differences could be used to predict a person’s intervention response but substantial investment in future research is needed to realise this.

description: The curved actin ``comet-tail'' of the bacterium Listeria monocytogenes is a visually striking signature of actin polymerization-based motility. Similar actin tails are associated with Shigella flexneri, spotted-fever Rickettsiae, the Vaccinia virus, and vesicles and microspheres in related in vitro systems. We show that the torque required to produce the curvature in the tail can arise from randomly placed actin filaments pushing the bacterium or particle. We find that the curvature magnitude determines the number of actively pushing filaments, independent of viscosity and of the molecular details of force generation. The variation of the curvature with time can be used to infer the dynamics of actin filaments at the bacterial surface.

Vaatamata HCV piiratud ravivõimalustele  ja peamiselt riskirühmades  tehtud valikulisele HBV-vastasele vaktsineerimisele suureneb haigestumus mitte ainult ägedatesse, vaid ka kroonilistesse haigusvormidesse. Haigestuvad nooremad inimesed (vanuses 15–29 a), muutunud on ka nakkuse ülekandmise viisid – enne põhiliselt narkootikumide süstimise kaudu, viimasel 2–3 aastal aga ka sugulisel teel. Uurimistulemused näitasid väga kõrget B- ja C-hepatiidiviirustega nakatumise taset Tallinna ja Ida-Virumaa narkomaanidel. HBV ja HCV, samuti seganakkuse (HBV + HCV) esinemine oli tõepäraselt sagedasem vangistuses viibivate HIV-positiivsete narkomaanide seas.

description: Inclusion complexes (ICs) of 2-hydroxypropyl-β-cyclodextrin with the essential oil (EO) from Seculo XXI cultivar of Psidium guajava were prepared using kneading (KN) and freeze-drying (FD) methods. The resulting ICs clusters have a nanometric size, with a diameter of approximately 80 and 40 nm for KN and FD, respectively. Complexation efficiency was 80.3% and 50.8% for KN and FD methods, respectively. The larvicidal activity of the EO in DMSO on A. aegypti had LC50 and LC90 values of 51.49 and 64.51 µg mL−1, respectively. For the KN method, the toxicity corresponded to 77.54 and 107.29 µg mL−1 for LC50 and LC90, respectively. FD method demonstrated toxicity at concentrations above 600 µg mL−1. Thus, ICs enable the use of EO in breeding sites for A. aegypti, thus being potential products to be commercially exploited.

description: We present new limits on resonant tb production in proton-antiproton collisions at 1.96 TeV, using 1.9 fb^-1 of data recorded with the CDF II detector at the Fermilab Tevatron. We reconstruct a candidate mass in events with a lepton, neutrino candidate, and two or three jets, and search for anomalous tb production as modeled by W'->tb. We set a new limit on a right-handed W' with standard model-like coupling, excluding any mass below 800 GeV at 95% C.L. The cross-section for any narrow, resonant tb production between 750 and 950 GeV is found to be less than 0.28 pb at 95% C.L. We also present an exclusion of the W' coupling strength versus W' mass over the range 300 to 950 GeV.

description: Previous phytochemical investigations reported that Calophyllum spp have biosynthesized a wide range of bioactive phenolics such as xanthones and coumarins. The phytochemical study conducted on the stem bark of C. canum has led to the isolation of eight trioxygenated xanthones namely: 5-methoxytrapezifolixanthone (1), 5-methoxyananixanthone (2), caloxanthone C (3), 1,5-dihydroxy-3-methoxy-4-isoprenylxanthone (4), 6-deoxyisojacareubin (5), euxanthone (6), trapezifolixanthone (7), ananixanthone (8), together with three common triterpenoids, β-sitosterol (9), friedelin (10), and stigmasterol (11). Furthermore, xanthones 1 and 2 were isolated for the first time as naturally occurring xanthones from the plant extract. The structures of these compounds were identified and elucidated using advanced spectroscopic techniques such as 1 D & 2 D NMR, MS, and FTIR. The neuroprotective property of selected compounds was tested through in vitro stroke model. Among all tested compounds, 1 µm of compounds 8, 9, and 10 showed significant neuroprotective activity via reduction of apoptosis by ∼ 50%.

description: Apparent competition is an indirect interaction between species that share natural resources without any mutual aggression but negatively affect each other if there is a common enemy. The negative results of the apparent competition are reflected in the species spatial segregation, which impacts the dynamics of their populations. Performing a series of stochastic simulations, we study a model where organisms of two prey species do not compete for space but share a common predator. Our outcomes elucidate the central role played by the predator in the pattern formation and coarsening dynamics in apparent competition models. Investigating the effects of predator mortality on the persistence of the species, we find a crossover between a curvature driven scaling regime and a coexistence scenario. For low predator mortality, spatial domains mainly inhabited by one type of prey arise, surrounded by interfaces that mostly contain predators. We demonstrate that the dynamics of the interface network are curvature driven whose coarsening follows a scaling law common to other nonlinear systems. The effects of the apparent competition decrease for high predator mortality, allowing organisms of two prey species to share a more significant fraction of lattice. Finally, our results reveal that predation capacity in single-prey domains influences the scaling power law that characterises the coarsening dynamics. Our findings may be helpful to biologists to understand the pattern formation and dynamics of biodiversity in systems with apparent competition.

Bostock and the End of the Climate Change Double Standard
Creators: name: Revesz, Richard
Publisher: name: Columbia Journal of Environmental Law

description: Greenhouse gases have never been given their rightful place at the regulatory table. Despite the statute’s text and legislative history, anti-regulation groups have consistently argued that the modern Clean Air Act does not apply to these contaminants. In Massachusetts v. EPA, the Court held that greenhouse gases are air pollutants for the purposes of the Clean Air Act. Thereafter, the Environmental Protection Agency found that greenhouse gases “endanger” public health and welfare and, thus, could be regulated under the Act. These two events should have definitively resolved the issue. Instead, greenhouse gases have been subjected to a double standard and treated as regulatory pariahs. Perhaps motivated by the presence of four dissenters in Massachusetts v. EPA, opponents of greenhouse gas regulation have pushed hard during the last decade to limit the reach of that case, even though no such limitation could fairly be derived from the decision’s text. They have also raised ill-defined and amorphous “major question” roadblocks that are at odds with the structure of the Clean Air Act. The Supreme Court’s decision in Bostock v. Clayton County opened the door to ending this pernicious greenhouse gas exceptionalism, and ensured that, going forward, greenhouse gases are treated like all other pollutants that meet the requirements for regulation. Although the majority and the two dissents in Bostock set forth different interpretive approaches for how to deal with a half-century-old statute, the interpretive reasoning of each approach, if applied to the Clean Air Act, reinforces the appropriateness of greenhouse gas regulation. Guided by the blueprint of all three Bostock opinions, this Article performs a deep dive into the legislative materials surrounding the enactment of the Clean Air Act of 1970, uncovering a treasure trove of sources that had not previously been part of the public discourse. It shows how, under the interpretive approach of each of the three opinions, greenhouse gases are unquestionably pollutants for the purposes of the Clean Air Act. Because the approaches in the majority and dissents in Bostock—and thus a majority of the current Court—all point in the same direction, the era of greenhouse gas exceptionalism should now be over.

Breeding behavior and feeding habits of the bald eagle (Haliaeetus leucocephalus L.) on San Juan Island, Washington

description: The breeding behavior and feeding habits of the bald eagle (Haliaeetus leucocephalus L.) were studied during 1962 and 1963 on San Juan Island, Washington. The primary aim of the study was to acquire information which would relate to the general decline in bald eagle numbers. Thirteen bald eagle nests were found on San Juan Island. On the basis of the spacing of these nests, the density of breeding eagles was considered to be low. The number of bald eagles varied throughout the year; the highest numbers were present in February and the lowest numbers in October. The change in eagle numbers was caused by the fluctuating numbers of juveniles. Two active nests were kept under observation, one in 1962 and another in 1963. The breeding eagles showed hostility toward intruders such as adult and juvenile bald eagles and man in the vicinity of their nesting site. The birds showed indifference toward intrusions of red-tailed hawks, crows and gulls. The chronology of breeding activities on San Juan Island was approximated with the aid of local information and with findings of former investigators. Egg-laying occurs between March 4 and 19; hatching between April 8 and 14. The young spend 12 to 1 3 weeks in the nest during which time parental attention gradually decreases. During the first 5 weeks of the youngs' life the nest is constantly guarded by one of the parents. Parental attention markedly decreases after the young start their wing exercises at the age of 8 to 9 weeks. In general, the female parent spent three times as much time at the nest as did the male. Food was brought to the nest at irregular intervals by both the female and male parents. The young were fed mainly by the female during the first seven weeks of their life; later the young fed themselves. No appreciable change in the amount of food supplied to the young during their nest life was observed. Young of the same nest were similar in size and indications of maltreatment from the others or from the parents were not observed. Most of the food brought to the nest consisted of rabbit carrion. This type of food item was available throughout the year due to the rabbits' high mortality resulting from collision with automobiles on the roads. Fish was fed to the young during the first six weeks of their life; thereafter, mainly rabbit was consumed. Rabbit carrion was the primary source of food for young eagles in their post-nestling period. The destruction of breeding habitat by real estate developments is the major cause of decline in numbers of bald eagles on San Juan Island.

description: The United States Office of Employment Security, early in 1962, reported that there were nearly five million available workers unemployed in the United States (3). An economic recession causing industry to cut back on production, more efficient methods in the manufacturing process, and the rapid changes in labor brought about by automation were listed as a few of the causes contributing to this condition. Another cause as depicted by an industry-produced film, "The Awesome Servant," showed that a large number of Americans that have had their jobs taken over by a machine have not been re-hired because they lack an employable skill. The p light of labor was portrayed by showing that machines have either replaced or displaced laborers. Those who have skills have been displaced to help build machines, market them, tend, or repair them. Those workers who have been replaced by the machines, and do not have technical skills, are finding it difficult to remain employed . The film also indicated that many companies are keeping their displaced employees on paroles and training them for other jobs . However, other organizations must release their employees and are forcing them to look for work elsewhere (5).

description: Kõik, mis põhjustab organismis muutusi, tekitab stressi. Stress ei ole haigus, vaid igapäevase elu loomupärane osa. Kroonilise  stressi hilistagajärjena võivad aga  ilmneda erinevad  tervisehäired. Pikaajalise stressi allikad on tihti psüühilised. Pikemat aega pöörati erilist tähelepanu stressi seosele seedeelundite haigustega. Viimastel aastatel on põhitähelepanu koondunud stressi ja vereringeelundite haiguste seose uurimisele ning leitud, et vaimse stressi osa nende haiguste tekkes võib olla ülehinnatud.
