Evolving spherical boson stars on a 3D cartesian grid
Creators: name: Guzman, F. Siddhartha
Publisher: name: arXiv
Year: 2004
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: A code to evolve boson stars in 3D is presented as the starting point for the evolution of scalar field systems with arbitrary symmetries. It was possible to reproduce the known results related to perturbations discovered with 1D numerical codes in the past, which include evolution of stable and unstable equilibrium configurations. In addition, the apparent and event horizons masses of a collapsing boson star are shown for the first time. The present code is expected to be useful at evolving possible sources of gravitational waves related to scalar field objects and to handle toy models of systems perturbed with scalar fields in 3D.

description: The surface reconstruction of the Fe catalyst films due to high temperature processing in hydrogen prior to nanotube nucleation and its effect on the growth morphologies of partially filled carbon nanotubes (CNTs) synthesized using atmospheric pressure chemical vapor deposition (APCVD) of propane was investigated. Results show that pre-heating of the catalyst film deeply influences the particle size distribution, which governs the growth morphologies of the corresponding CNTs. The distribution of the catalyst particles over the Si substrate was analyzed before and after the heat treatment by atomic force microscopy (AFM) which reveals that heat treatment causes clusters of catalyst to coalesce and form macroscopic islands. The X-ray diffraction (XRD) pattern of the grown material indicates that they are graphitic in nature. Scanning electron microscopy (SEM) analysis suggested that the growth density strongly depends on the pre heat treatment of the Fe catalyst film. Multiwalled CNTs with partial catalyst filling were observed via high-resolution transmission electron microscopy (HRTEM) measurements. The degree of graphitization of the CNTs also depends on the pre heating as demonstrated by Raman analysis. A simple model for the growth of partially catalyst filled nanotubes is proposed.

Self Similar Adiabatic Strong Explosion in a Medium Gravitationally Free Falling to a Point Mass
Creators: name: Yalinewich, Almog
Publisher: name: arXiv
Year: 2020
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: We develop a generalisation to the classical Sedov Taylor explosion where the medium free falls to a point mass at the centre of the explosion. To verify our analytic results, we compare them to a suite of numerical simulations. We find that there exists a critical energy below which, instead of propagating outward the shock stalls and collapses under gravity. Furthermore, we find that the value of the critical energy threshold decreases when the adiabatic index increases and material is more evenly distributed within the shocked region. We apply this model to the problem of a shock bounce in core collapse supernova, in which the proto neutron star serves as the point mass. The relation between the threshold energy and the distribution of mass in the shock might help explain how turbulence prevents shock stalling and recession in a core collapse supernova explosion.
“I Don’t Know if It Wanted Me to Dance”. On Leading and Being Led in Human-eGate Interaction

description: Automated border controls, like eGates, are becoming an everyday experience when travelling. Besides their contested character as a biometrical border, these access control systems are either taken for granted in their smooth functioning or are seen as forcing humans into a scripted sequence of action. Based on a technographic study of laboratory eGate-testings in Germany, we argue for a different approach in understanding the specific human-machine-interaction. Drawing on Pickering’s (2012) “dance of agency”, we will show that the reciprocal interaction of using an eGate comprises facets of routine, anticipation and mimicry. Attuning to the oscillation of agency, where leading and being led is reciprocal, we must recognize that even automated systems rely on human beings, their bodies and their senses to make adjustments. The analysis suggests that both entities are interwoven in an asymmetric way, which allows seeing it from a new angle that incorporates usability and STS-perspectives to approach border technologies. In doing so, the focus on (laboratory) testing shows that it can bring back and secure human agency within interactions with border technologies.

description: A very simple procedure to calculate eigenenergies of quantum anharmonic oscillators is presented. The method, exact but for numerical computations, consists merely in requiring the vanishing of the Wronskian of two solutions which are regular respectively at the origin and at infinity. The first one can be represented by its series expansion; for the second one, an asymptotic expansion is available. The procedure is illustrated by application to quartic and sextic oscillators.

Hydrodynamic simulations of molecular outflows driven by slow-precessing protostellar jets

Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We present hydrodynamic simulations of molecular outflows driven by jets with a long period of precession, motivated by observations of arc-like features and S-symmetry in outflows associated with young stars. We simulate images of not only H2 vibrational and CO rotational emission lines, but also of atomic emission. The density cross section displays a jaw-like cavity, independent of precession rate. In molecular hydrogen, however, we find ordered chains of bow shocks and meandering streamers which contrast with the chaotic structure produced by jets in rapid precession. A feature particularly dominant in atomic emission is a stagnant point in the flow that remains near the inlet and alters shape and brightness as the jet skims by. Under the present conditions, slow jet precession yields a relatively high fraction of mass accelerated to high speeds, as also attested to in simulated CO line profiles. Many outflow structures, characterised by HH222 (continuous ribbon), HH240 (asymmetric chains of bow shocks) and RNO43N (protruding cavities), are probably related to the slow precession model.

description: Les politiques nutritionnelles émettent des recommandations visant à améliorer la qualité de l'alimentation. On peut s'interroger sur la portée sociale de ces normes nutritionnelles qui seraient particulièrement difficiles à respecter pour les populations à bas revenu. Aussi est-il opportun de vérifier dans quelle mesure, sur le plan théorique, les recommandations nutritionnelles peuvent être remplies avec un faible budget alimentaire. Les enquêtes montrent que la consommation alimentaire des populations pauvres reflète le poids des contraintes financières sous diverses formes. Ces contraintes ont-elles un impact significatif sur la qualité des produits consommés et peuvent-elles entraîner des déséquilibres alimentaires ? Cette interrogation débouche sur un débat majeur, celui de l'opportunité d'une politique d'intervention sur les prix alimentaires.

description: Dans le contexte contemporain de multiplication des crises sanitaires, de nombreux travaux en sciences économiques et sociales ont cherché à décrire et analyser le comportement des consommateurs face au risque alimentaire. Ces travaux partagent globalement deux prémisses : ils considèrent l'acte de consommation comme un comportement individuel et attribuent aux consommateurs des "perceptions du risque" qui orientent leurs choix. Une critique de ces deux axiomes amène à soulever la question de la spécificité du risque alimentaire et de ses dimensions sociales et politiques.

description: Nanomaterials (NMs) can be produced in plenty of variants posing several challenges for NM hazard and risk assessment. Metabolomic profiling of NM-treated cells and tissues allows for insights into underlying Mode-of-Action (MoA) and offers several advantages in this context. It supports the description of Adverse Outcome Pathways (AOPs) and, therefore, tailored AOP-based hazard testing strategies. Moreover, it bears great potential for biomarker discovery supporting toxicity prediction. Here, we applied metabolomics profiling to cells treated with four well-selected SiO2 variants, differing in structure, size and surface charge. TiO2 NM-105 served as a benchmark. Responses were studied in vitro in rat lung epithelial cells (RLE-6TN) and alveolar macrophages (NR8383) and compared to in vivo responses in rat lung tissues obtained from in vivo instillation and short-term inhalation studies (STIS). Time- and concentration-dependent changes were observed in both in vitro models but with cell-type specific responses. Overall, the levels of lipids and biogenic amines (BAs) tended to increase in epithelial cells but decreased in macrophages. Many identified metabolites like Met-SO, hydroxy-Pro and spermidine were related to oxidative stress, indicating that oxidative stress contributes to the MoA for the selected NMs. Several biomarker candidates such as Asp, Asn, Ser, Pro, spermidine, putrescine and LysoPCaC16:1 were identified in vitro and verified in vivo. In this study, we successfully applied a metabolomics workflow for in vitro and in vivo samples, which proved to be well suited to identify potential biomarkers, to gain insights into NM structure–activity relationship and into the underlying MoA.

Especially we discuss the large $N_c$ $ππ$ scatterings by making use of the partial wave $S$ matrix parametrization form. We find that the $σ$ pole may move to the negative real axis on the second sheet of the complex $s$ plane, therefore it raises the interesting question that this `$σ$' pole may be related to the $σ$ in the linear $σ$ model.

description: L'exposition prolongée au méthylmercure, principalement présent dans les produits de la mer (poissons, mollusques et crustacés), provoque des troubles profonds du système nerveux. L'objectif de cette étude est de quantifier ce risque pour la population française à partir de données de consommation et de contamination. Les consommateurs français susceptibles d'être exposés fortement et durablement à ce contaminant sont identifiés en fonction de leur âge, de leur sexe et de leurs caractéristiques socioéconomiques, afin que des recommandations adaptées aux consommateurs à risque puissent être éventuellement émises. Nous estimons pour l'année 2001 que 6% de la classe d'âge des enfants de moins de 3 ans sont des individus à risque. Par ailleurs, aucun enfant vivant dans un ménage à revenu modeste n'est un individu à risque.

description: In this paper we present the temperature-dependent emissivity of a silicon sample, estimated from its cool-down curve in a constant low temperature environment ($\approx$ 82K). The emissivity value follow a linear dependency in the 120-260 K temperature range. This result is of great interest to the LIGO Voyager gravitational wave interferometer project since it would mean that no extra high thermal emissivity coating on the test masses would be required in order to cool them down to 123 K. The results presented here indicate that bulk silicon itself can have sufficient thermal emissivity in order to cool the 200 kg LIGO Voyager test masses only by radiation in a reasonable short amount of time (less than a week). However, it is still not clear if the natural emissivity of silicon will be sufficient to maintain the LIGO Voyager test masses at the desired temperature (123 K) while removing power absorbed by the test masses. With the present results, a black coating on the barrel surface of the test masses would be necessary if power in excess of 6 W is delivered. However, the agreement we found between the hemispherical emissivity obtained by a theory of semi-transparent Silicon and the obtained experimental results makes us believe that the LIGO Voyager test masses, because of their dimensions, will have effective emissivities around 0.7, which would be enough to remove about 8.6 W (7.5 W) for a shield at 60 K (80K). This hypothesis may be confirmed in the near future with new measurements.

Acute effect of cigarette smoke on TNF-α and proteases released by macrophages
Creators: name: Demirjian, Loutfig
Publisher: name: University of British Columbia
Year: 2009

description: Pulmonary emphysema is a major cause of mortality and morbidity in chronic obstructive pulmonary disease (COPD). Cigarette smoking is a major risk factor in the development of pulmonary emphysema. In this study we investigated the acute effect of cigarette smoke in vitro on the production of tumour necrosis factor-α (TNF- α) using differentiated U937 cells, a human monocyte cell line used as a macrophage model system and human alveolar macrophages (AM). We found that stimulation of the macrophages with cigarette smoke media (CSM) leads to a rapid activation of extracellular-regulated kinases 1 and 2 (ERK1/2), p90RSK, and a transient decrease in phosphorylation of PKB/akt in differentiated U937 cells and alveolar macrophages. The CSM also caused the subsequent induction of TNF- α release in U937 differentiated macrophages, whereas alveolar macrophages showed no consistent change in TNF- α release. Our studies revealed that U0126, an inhibitor of the ERK1/2 pathway, markedly suppressed CSM-induced TNF- α release in U937 differentiated macrophages. Consistent with this finding, U0126 blocked CSM-stimulated ERK1/2 phosphorylation, as well as phosphorylation of the downstream kinase, p90RSK. On the other hand, the PI3-K inhibitor, LY294002 and epidermal growth factor receptor (EGFR)-specific inhibitor, AG1478 did not suppress the release of TNF- α by U937 differentiated macrophages. Thus, CSM induction of TNF- α production by U937 differentiated macrophages is regulated primarily via the ERK1/2 pathway. In contrast, CSM suppressed or had no effect on TNF- α release by alveolar macrophages, even though CSM induced the phosphorylation of ERK1/2. This suggests that alveolar macrophages may utilize adifferent signaling pathway for TNF- α production. In addition, this study also investigated the acute effect of cigarette smoke solution in vitro on the release of Cathepsin L, Matrix Metalloprotease-1, 7, 9 and 12 by AM , from which only Cathepsin L showed a slight but statistically significant increase after smoke exposure.

Besides being considered one of the greatest fern producing regions of Brazil, a signiﬁcant number of local family farmers have in the extraction of this species their main income source. The results of this study allowed us to verify the existence of a very differentiated compensation in different agents involved, emphasizing the predominance of precarious and informal commercial relations, and the inexistence of representation and organization of the involved players. This situation is a consequence of the illegal and clandestine character of this activity, in view of the effective environmental legislation in Rio Grande do Sul State.

description: The irrigation programs started in the late 60’s were chiefly responsible for the impressive development occurred in the Petrolina/Juazeiro areas. Along with irrigation, came some agricultural enterprises that had been previously dedicated to other economic activities such as extensive cattle production. The main hypothesis of this study is that modern technology used in irrigation, combined with input usage, allow for a production level near or at the production frontier. Preliminary studies concluded that there is heterogeneity among enterprises, where similar technological packages are used and fruit production is the dominant production. Therefore, this study analyzes technical efficiency of agricultural enterprises in the studied area using a Translog function model to attain an efficient frontier. Results show that the model has significant efficiency scores. The comparative analysis among main irrigation areas shows that most of the efficient firms are located in the government delimited irrigation areas of Nilo Coelho and Maniçoba or outside delimited irrigation areas.

description: The purpose of the research was to determine, through the calculation of net present value and internal return rate, the viability of fruit production in the North area of Rio de Janeiro State, as well as to identify, using the Monte Carlo Method, the risk of each activity. The results show that fruit production can be a good alternative to the region. All the analyzed activities presented satisfactory profitability, and the highest internal return rates found for passion fruit, soursop, pineapple and sugar apple. The variable with greatest effect on profitability was the product sale price, and equally important were labor cost, price of fertilizers and cost of irrigation equipment. Pineapple, cocoanut, sugar apple, passion fruit and soursop practically offered no economic risks, while the greatest risks were presented by mango and guava.

description: The purpose of this study is to analyze the agricultural seasonal labor contract system and mainly the rural labor cooperatives, from the legal system’s point of view. Legal institutions are important components that affect the agricultural seasonal labor contract. Therefore, these institutions trend to restrict some contract frameworks and to provide incentive to other contracts. The work verified that rural labor cooperatives have high restrictions from legal institutions. The reason is the high incidence of corruption in this contract system. Thus, there is a potential increase in the transactions cost of the labor contract system.

description: The carbon chain ions HC$_3$O$^+$ and HC$_3$S$^+$ - longer variants of the famous "X-ogen" line carrier HCO$^+$ - have been observed for the first time using two cryogenic 22-pole ion trap apparatus (FELion, Coltrap) and two different light sources: the Free Electron Laser for Infrared eXperiments (FELIX), which was operated between 500 and 2500 cm$^{-1}$ and an optical parametric oscillator operating near 3200 cm$^{-1}$; signals from both experiments were detected by infrared predissociation action spectroscopy. The majority of vibrational fundamentals were observed for both ions and their vibrational wavenumbers compare very favorably with results from high-level anharmonic force field calculations performed here at the coupled-cluster level of theory. As the action spectroscopic scheme probes the Ne-tagged weakly bound variants, Ne$-$HC$_3$O$^+$ and Ne$-$HC$_3$S$^+$, corresponding calculations of these systems were also performed. Differences in the structures and molecular force fields between the bare ions and their Ne-tagged complexes are found to be very small.

description: The maintenance and/or expansion of land form the central axle along which family farming organize their livelihood and work.. This paper analyzes these producers’ strategies that are related to division of inheritance and succession, and the forms of acquisition of new areas. The survey on the characteristics of families and property was carried out by a questionnaire in 89 familiar producers of three cities of São José do Rio Preto (SP) region. Next, one third of those answering the questionnaire were interviewed in the same cities. The analysis of agrarian strategies showed a great diversity in the manner of inheritance sharing and conducting succession; although being basically supported in both processes by traditional rules they seem to follow the legal the legal rules. Regarding to acquisition strategies of more land, it was noticed that producers are able to organize complex forms of capitalization, which are centralized in bigger efforts at work and containment of expenses, besides the use of favorable public policies and customary practices. The intra-familiar arrangements and the forms of kinship cooperation also appeared as equally important to the property expansion.

description: Three different configurations of compact magneto-optical sources of slow Rb atoms(LVIS, 2D(+)-MOT and 2D-MOT) were compared with each other at fixed geometry of cooling laser beams. A precise control of the intensity balances between the four separate transverse cooling laser beams provided a total continuous flux of cold atoms from the LVIS and 2D(+)-MOT sources about 8x10^9 atoms/s at total laser power of 60 mW. The flux was measured directly from the loading rate of a 3D-MOT, placed 34 cm downstream from the sources. Average velocities of the cooled atomic beam for the LVIS and 2D(+)-MOT sources were about 8.5 m/s and 11 m/s respectively. An essential advantage of the compact magneto-optical sources is that their background flux of thermal atoms is two to three orders of the magnitude smaller than the flux of slow atoms.

description: The object of this study is the environmental park “Chico Mendes” located in Rio Branco - Acre. Being unique and all-enclosing in its nature it is a public asset. The contingent valuation makes possible the determination of the total economic value total of a public asset. The people’s willingness to pay for the park maintenance and conservation shows a determination of the consumers’ preference. This work attempts to determine the total economic value of the park. The results show that family income, value of monthly contribution, sex and age explain the probability of a person to contribute to the park conservation. Finally, bootstrapping and risk analysis provide greater safety to the results found.

description: Indonesia adalah negara yang mempunyai biodiversitas alam kedua di dunia setelah Brasil. Penggunaan obat berasal dari tumbuhan adalah bukan hal ayng asing bagi masayarakat Indonesia dimanapun mereka berada. Bahkan beberapa studi etnofarmakologi sudah dilakukan di berbagai suku di Indonesia. Masyarakat Indonesia banyak mengkonsumsi simplisia tumbuhan obat maupun ektrak tumbuhan dalam bentuk jamu.Jamu adalah obat herbal tradisional Indonesia yang biasa dipakai masyarakat Indonesia untuk menjaga kesehatan dan mengobati penyakit. Jamu adalah sangat populer di daerah pedesaan maupun perkotaan. Jamu telah memperoleh manfaat potensial, baik secara ekonomi maupun klinis. Dalam perijinannya, Badan Pengawas Obat dan Makanan (BPOM) mengklasifikasikan sediaan produk dari tanaman obat menjadi tiga kategori, yaitu Jamu, Obat Herbal Terstandar (OHT) dan Fitofarmaka. Karena aktivitas biologis jamu sebagian besar didasarkan pada data empiris, diperlukan lebih banyak penelitian untuk membuktikan secara ilmiah profil farmakologis, data efikasi, serta data keamanan. Hal ini lah yang mendasari klasifikasi OHT maupun Fitofarmaka. OHT adalah sediaan obat bahan alam yang telah dibuktikan keamanan dan khasiatnya secara ilmiah dengan uji praklinik dan bahan bakunya telah di standarisasi. Sedangkan Fitofarmaka adalah sediaan obat bahan alam yang telah dibuktikan keamanan dan khasiatnya secara ilmiah dengan uji praklinik dan uji klinik, bahan baku dan produk jadinya telah di standarisasi. Dalam definisimya, obat tradisional adalah bahan atau ramuan bahan yang berupa bahan tumbuhan, bahan hewan, bahan mineral, sediaan sarian (galenik) atau campuran dari bahan tersebut, yang secara turun-temurun telah digunakan untuk pengobatan berdasarkan pengalaman. Dalam hal ini regulasi terkini menyebutkan bahwa Jamu adalah obat tradisional Indonesia. Menurut regulasi OHT dan Fitofarmaka adalah “obat’ yang sudah terstandarkan dan berasal dari alam, serta didasari bukan data empiris seperti jamu, namun data saintifik praklinis maupun klinis. Untuk membedakan klasifikasi antara obat tradisional yang berdasarkan data empiris dan obat “modern” yang berdasarkan data saintifik, beberapa Menteri Republik Indonesia ( Menteri Ristek, Menteri Kesehatan, dan Menteri perindustrian) sepakat untuk menggunakan istilah Obat Modern Asli Indonesia (OMAI) untuk menyebut obat dari bahan alam yang sudah distudi secara saintifik baik dalam bentuk OHT maupun Fitofarmaka. Banyak hal harus dikaji agar OMAI dapat dipakai di fasilitas pelayanan kesehatan formal di Indonesia. Masalah teknis termasuk standarisasi produk OMAI, hak kekayaan intelektual, mutu produk, serta aspek ekonomi petani perlu dipertimbangkan.

description: Infectious and non-infectious diseases have caused a huge burden to the affected people as well as the healthcare systems across the globe. Antimicrobial resistance is on the rise and becoming a major threat in the efforts to treat diseases. Medicinal plants and fungi offer alternative solutions to this challenge and Bersama abyssinica is one of the plants used for treatment of various diseases such as tumors, dysentery, and roundworm infestation. This study aimed to isolate secondary metabolites from the stem barks and leaves of two subsp. of B. abyssinica and their endophytic fungi. The stem bark and leaves of the two subsp. of B. abyssinica were collected from Mt. Elgon National Forest. A portion of the collected plant materials was used for fungal endophyte isolation while the other portion was dried for extraction of secondary metabolites. The isolated pure fungal endophytes were subjected to fermentation on solid media followed by subsequent extraction of secondary metabolites.  The extracts from both plant material and endophytic fungi were subjected to fractionation using column chromatography over silica gel and Sephadex LH-20 followed by further purification by High-Performance Liquid Chromatography (HPLC). Structure elucidation of pure compounds was done using a combination of spectroscopic techniques that include 1D and 2D NMR spectroscopy and Liquid Chromatography Mass Spectrometry. The relative configurations were defined by single-crystal X-ray crystallography and Nuclear Overhauser Effect Spectroscopy (NOESY) correlations. Structures for thirty compounds (17 – 46) were successfully elucidated with eight previously undescribed compounds (17 – 19, 33 – 36, and 41). Paulliniogenin A (17), 16β-hydroxybersamagenin 1,3,5-orthoacetate (20), 1β-acetoxy-3β,5β-dihydroxy-15-methoxy-16,19-dioxobufa-14(15),20,22-trienolide (35), epicocconigrone A (44) showed cytotoxic activities against Hela (KB3.1) cell lines with IC50 in the range of 1.4 ± 0.77 µM and 5.9 ± 1.89 µM. 1,2,3,6-tetra-O-galloyl-β-d-glucose (24), epicoccolide B (43), epicocconigrone A (44) and eleganketal A (45) showed weak cytotoxicity ranging between 11.7 ± 6.78 µM and 35.82 ± 5.40 µM for mouse fibroblast (L929) cell lines. Compounds 24, 43, and 45 exhibited antibacterial activity against E. coli and B. subtilis with an MIC value of 33.3 µg/mL. Moreover, 45 exhibited antifungal activity against T. tonsurans with an MIC value of 18.75 µg/mL. The bioactive compounds are potential lead compounds for the development of new drugs.
