description: Subject and purpose of work: The objective of this work was to identify the factors which determine the social and economic development, present the disproportions in the development of regions, show the relations between the level of the economy and the pace of development of regions, and to determine the growth poles. Materials and methods: The spatial scope of the research covered 16 voivodeships and the time range included years 2005 and 2013. The sources of materials constituted: home and foreign literature, GUS (Central Statistical Office) data. The Pearson correlation coefficient and descriptive, tabular, graphic, index methods were used to analyse and present data. Results: The conducted research showed that there is a big disproportion between the regions. The increase in disparities is visible, among other things, concerning the unemployment level and percentage of people who work in the services’ sector. The voivodeships with the best economic situation and the highest level of factors determining the development were the growth poles. These voivodeships include definitely the Mazowieckie Voivodeship, then Śląskie, Wielkopolskie and Małopolskie Voivodeships. Conclusions: It has been confirmed that there is a correlation between the economic situation and the pace of development of regions. The calculated correlation coefficients allowed to assess that with regards to most of the features determining the regional development, there occurred moderate or strong significant dependency with the economic situation of the region.

description: Subject and purpose of work: The aim of the study is to make a characteristic and evaluation of the conditions of environmental activities of companies representing the bioeconomy sector located in environmentally valuable areas of Lublin Voivodeship. The study also identifies key factors and barriers to eco-activity from the perspective of the surveyed companies. Materials and methods: To achieve the goal a review of literature and surveys were conducted in 2013 in 30 communes of the Lublin province (Poland), characterized by the highest level of the indicator of ecological value. The study used the method of diagnostic survey with a questionnaire interview. Results: Environment-friendly activities undertaken in the studied companies were conditioned largely by economic factors and the need to adapt the organization to meet the standards of environmental protection. Among the problems concerning determinants of eco-friendly activity entrepreneurs pointed high cost of adapting the organization to the increasingly stringent environmental legislation and organizational difficulties to adapt to these regulations. Conclusions: Bioeconomy sector companies operating in environmentally valuable areas are characterized by mutual harmonious relationship with the local natural environment. In the study group, there is a need to promote awareness of the possibility of external support for environmental activities.

description: This article presents case studies detailing the learning trajectories of two physical education (cooperating) teachers as they strive to establish and maintain their identity as competent and confident supervisors to pre-service teachers on school placement. The cooperating teachers who participated in the study share their experiences in attempting to construct a professional identity within the school placement triad. Lave and Wenger’s (1991) theory of situated learning and the concept of legitimate peripheral participation were employed to investigate each of the cooperating teacher’s journeys in their attempt to shape their professional identity through participation in a variety of professional learning communities. The data revealed that the cooperating teachers experienced various forms of legitimate peripheral participation and, as a result, their learning trajectories and attempts to construct professional identities were diverse. The cooperating teachers’ learning did not always follow a positive trajectory, often meeting obstacles, resulting in the teachers experiencing both highs and lows during the supervision process.

description: We investigate analytic classical solutions in open string field theory which are constructed in terms of marginal operators. In the classical background, we evaluate a coupling between an on-shell closed string state and the open string field. The resulting coupling exhibits periodic behavior as expected from the marginal boundary deformation of background Wilson lines or a marginal tachyon lump. We confirm that the solutions in open string field theory correspond to a class of marginal deformations in conformal field theory.

description: Interstellar dust plays a crucial role in the evolution of the Universe by assisting the formation of molecules, by triggering the formation of the first low-mass stars, and by absorbing stellar ultraviolet-optical light and subsequently re-emitting it at infrared/millimetre wavelengths. Dust is thought to be produced predominantly in the envelopes of evolved (age >1 Gyr), low-mass stars. This picture has, however, recently been brought into question by the discovery of large masses of dust in the host galaxies of quasars at redshift z>6, when the age of the Universe was less than 1 Gyr. Theoretical studies, corroborated by observations of nearby supernova remnants, have suggested that supernovae provide a fast and efficient dust formation environment in the early Universe. Here we report infrared observations of a quasar at redshift 6.2, which are used to obtain directly its dust extinction curve. We then show that such a curve is in excellent agreement with supernova dust models. This result demonstrates a supernova origin for dust in this high-redshift quasar, from which we infer that most of the dust at high redshifts has probably the same origin.

description: Autismus mit seinen verschiedenen Ausprägungen zählt zu den komplexen Entwicklungsstörungen. Für Lehrkräfte ist es eine grosse Herausforderung, den betroffenen Kindern eine gute und adäquate schulische Förderung zu geben. Diese erfolgt in Sonderschulen und mit dem neuen Schulgesetz auch vermehrt integrativ in Regelklassen. Entscheidend ist jedoch nicht der Schulort, sondern das Verstehen von und das Wissen über die spezifischen Bedürfnisse autistischer Kinder beim Lernen. Konkrete Gelingensbedingungen für die schulische Förderung wurden in Fachkreisen postuliert. In dieser Arbeit wird untersucht, inwieweit diese in der schulischen Praxis im Kanton Graubünden umgesetzt sind und als wie wichtig sie erachtet werden. Dies geschieht mittels einer Umfrage bei sonderpädagogischen Lehrkräften, die mit autistischen Kindern arbeiten. Daraus wird Handlungsbedarf abgeleitet. Abschliessend werden Optimierungsmöglichkeiten für die schulische Förderung in der Integration und an Sonderschulen beschrieben.
Phylogenetic analysis of genes encoding photosynthesis proteins in cyanophage isolates and natural virus communities

description: Cyanophages infecting cyanobacteria of the genera Synechococcus and Prochlorococcus are abundant and ubiquitous in aquatic environments. Sequencing of some cyanophage isolates has revealed homologous genes to psbA and psbD that encode key proteins for photosynthesis. Using molecular techniques, this thesis explored the phylogenetic diversity of these genes in cyanophage isolates and natural virus communities. First, I amplified cyanophages psbA and psbD genes fragments from myoviruses infecting marine Synechococcus strain DC2 (=WH7803) and compared them phylogenetically. I demonstrated that psbA was present in all cyanophage genomes, while psbD was presented in only half of them. Moreover, gene-based phylogenies revealed similar tree topologies for both genes. This suggests that psbA and psbD were acquired coordinately but psbD was lost during multiple events. Next, I compared the genetic diversity of viral psbA from a range of environments with the goal of determining if sequences cluster based upon their environments. Phylogenetic reconstruction showed that viral psbA sequences from fresh waters have an evolutionary history distinct from their marine equivalents. Moreover, photosynthesis sequences from cyanophages infecting neither Prochlorococcus nor ' Synechococcus were distinct, as were sequences from different phage families (e.g., podoviruses vs myoviruses). This thesis confirmed that viral psb genes have their own evolutionary history that is distinct from that of their host.

description: The space environment around the Earth is populated by more than 130 million objects of 1 mm in size and larger, and future predictions shows that this amount is destined to increase, even if mitigation measures are implemented at a far better rate than today. These objects can hit and damage a spacecraft or its components. It is thus necessary to assess the risk level for a satellite during its mission lifetime. Few software packages perform this analysis, and most of them employ time-consuming ray-tracing methodology, where particles are randomly sampled from relevant distributions. In addition, they tend not to consider the risk associated with the secondary debris clouds. The paper presents the development of a vulnerability assessment model, which relies on a fully statistical procedure: the debris fluxes are directly used combining them with the concept of the vulnerable zone, avoiding the random sampling the debris fluxes. A novel methodology is presented to predict damage to internal components. It models the interaction between the components and the secondary debris cloud through basic geometric operations, considering mutual shielding and shadowing between internal components. The methodologies are tested against state-of-the-art software for relevant test cases, comparing results on external structures and internal components.

description: The heat transfer phenomena for single- and double-layer inclined absorbers, which absorb synchrotron radiation has been studied using analytical and numerical methods. Photon penetration through the metal layers has been included and the effects of the spectral variation of the absorption coefficients and variable thermal conductivities have been examined. Different thickness ratios and inclination angles have been studied for double layer absorbers and it has been shown that double-layer inclined absorbers significantly reduce the peak temperatures. In the current study, thermoplasmonic characteristics of cerium nanoparticles with spherical, core-shell and rod shapes were investigated. In order to investigate these characteristics, the interaction of synchrotron radiation emission as a function of the beam energy and cerium nanoparticles were simulated using the 3D finite element method. Firstly, absorption and extinction cross-sections were calculated. Then, increases in temperature due to synchrotron radiation emission as a function of the beam energy absorption were calculated in cerium nanoparticles by solving the heat equation. The obtained results showed that cerium nanorods are a more appropriate option for using in optothermal human cancer cells, tissues and tumor treatment methods. Furthermore, the produced heat devastates tumor tissues adjacent to nanoparticles without any hurt to sound tissues. Regarding the simplicity of ligands connection to cerium nanoparticles for targeting cancer cells, these nanoparticles are more appropriate to use in optothermal human cancer cells, tissues and tumors treatment.

description: Greenhouse trials were carried out to determine the effect of different ethanol solution concentrations oil the initial growth of'South Bay' lettuce. Lettuce plants in the twotrue leaf stage were dipped in for 2 minutes in a solution containing 0, 5, 10, 15 or 20% ethanol (v/v). Lettuce fresh weight and plant diameter were collected 30 days after treatment. Lettuce plants that received 10 or 15% dipping had the greatest plant diameter and dry weight compared to other treatments, representing about 21.2 and 19.5% increases in fresh weight, respectively. A 22.2% reduction in fresh weight was observed when plants were treated with 20% ethanol solutions. A tertiary relationship characterized the fresh weight response to ethanol rates (y = 109.64 - 0.56x + 0.62x2 - 0.033x3; r2=0.99).

description: The article is devoted to the rationale for the choice of financial indicators for the diagnosis of the financial condition of the enter-prise and determine the probability of their bankruptcy. In the context of a long economic crisis, which affected almost all enterprises of Ukraine, the issue of early diagnosis of the financial condition of enterprises and determining the probability of their bankruptcy is relevant. The most well-known in our time models for diagnosing the financial condition of the enterprise and determining the probability of their bankruptcy are not fully adequate in the specific conditions of the domestic economy. Therefore, it is important to select the most important indicators and give them priority in the relevant model. The task of the work is to test the theoretical studies on the selection and prioritization of financial indicators, which are planned to be used in the future to build models for the diagnosis of the financial con-dition of enterprises. The test is to assess the priority through the study of empirical data by means of factor and correlation analysis and comparison of empirical data studies with previous results of prioritization of financial indicators by the method of analysis of hierarchies and with the involvement of experts. It is shown that for the diagnosis of selected financial indicators are to be studied for multicollinearity. The financial indicators of the enterprises selected for the study were subjected to statistical analysis. The factor and correlation analy-sis of financial indicators on the basis of studies of financial statements of enterprises, revealed a weak mutual influence of indicators, which indicates their optimal choice. Factor analysis revealed the contribution of each of the financial indicators to the overall result. The financial indicators involved in the study can be used in the future to build neural network and fuzzy-logical models for assessing the probability of bankruptcy of enterprises. The research results can be aimed at building models for assessing the financial condition of the enterprise and the probability of their bankruptcy with the help of modern tools for modeling economic processes – fuzzy logic and neural networks – and checking the adequacy of the proposed models.

description: Interference trials were conducted under greenhouse conditions to determine the effects of mixed densities of smooth pigweed and common purslane on the initial growth of lettuce. Weeds were allowed to interfere with lettuce for 30 days before collecting plant dry matter of each species growing in the containers Densities used were 1, 2, 4, 6 and 8 weeds per container, along with the weed-free control. Monocultures of each weed were established along with the 50:50 proportion within each density, except for 1 plant per container. Interference of monostands of common purslane reduced lettuce dry matter accumulation more than smooth pigweed monostands within each density. Four common purslane plants per container reduced dry matter in as much as 6 or 8 smooth pigweed plants per container. In all cases, within a given density, 50:50 mixture treatments produced more lettuce dry matter than common purslane monocultures.

description: Area of influence experiments were established on high-organic matter soils to assess the effect of varying common lambsquarters distances on lettuce marketable yield and quality under two phosphorus (P) regimes. Banded (125 Kg/ha) or broadcast (250 Kg/ha) Ρ was applied before lettuce planting. A single 2-week-old common lambsquarters plant was transplanted in the center of each lettuce bed. Lettuce plants were arranged in pairs from the distance to the lambsquarters plant of a given treatment. A weed-free control was also established. Lettuce plants were harvested in pairs at distances of 0, 25, 50, 75, 100 and 125 cm to each side of the lambsquarters plant after season-long interference. Average head fresh weight was collected. Results indicate that lambsquarters severely reduced fresh weight and quality of lettuce plants as spacing decreased. In all cases, banded Ρ diminished the impact of lambsquarters on lettuce. Lettuce pairs grown at 75 cm or more from lambsquarters were apparently not affected by weed interference when Ρ was banded, whereas no effect was present at 100 cm or more when Ρ was broadcast. These data indicates that banding Ρ gives an additional advantage to lettuce within a given distance, reducing the area of influence of lambsquarters.

description: We study thermodynamic properties of Nf=2+1 QCD on the lattice adopting O(a)-improved Wilson quark action and Iwasaki gauge action. To cope with the problems due to explicit violation of the Poincare and chiral symmetries, we apply the Small Flow-time eXpansion (SFtX) method based on the gradient flow, which is a general method to correctly calculate any renormalized observables on the lattice. In this method, the matching coefficients in front of operators in the small flow-time expansion are calculated by perturbation theory. In a previous study using one-loop matching coefficients, we found that the SFtX method works well for the equation of state, chiral condensates and susceptibilities. In this paper, we study the effect of two-loop matching coefficients by Harlander et al. We also test the influence of the renormalization scale in the SFtX method. We find that, by adopting the mu_0 renormalization scale of Harlander et al. instead of the conventional mu_d=1/sqrt{8t} scale, the linear behavior at large t is improved so that we can perform the t -> 0 extrapolation of the SFtX method more confidently. In the calculation of the two-loop matching coefficients by Harlander et al., the equation of motion for quark fields was used. For the entropy density in which the equation of motion has no effects, we find that the results using the two-loop coefficients agree well with those using one-loop coefficients. On the other hand, for the trace anomaly which is affected by the equation of motion, we find discrepancies between the one- and two-loop results at high temperatures. By comparing the results of one-loop coefficients with and without using the equation of motion, the main origin of the discrepancies is suggested to be attributed to O((aT)^2)=O(1/N_t^2) discretization errors in the equation of motion at N_t =< 10.

title: Regulation Of Transcription By RNA Polymerase II In S. pombe

Publisher: name: The Open University
Year: 2018

description: An understanding of the mechanisms underlying the various stages of transcription is crucial to find solutions to the problems caused by mis-expression of genes that may give rise to a host of human diseases. My thesis research focusses on an analysis of the RNA Polymerase II elongation factor Ell1/Eaf1 in S. pombe. Eleven-nineteen lysine-rich in leukemia (ELL) is encoded by a gene involved in translocations with MLL in leukemia and forms a tight complex with ELL-associated factors (EAF). ELL/EAF is an RNA polymerase II elongation factor that in metazoa can assemble into a larger assembly that also includes P-TEFb and other proteins encoded by genes involved in MLL translocations. This larger assembly, sometimes called SEC, binds to a specific "docking site" in the metazoan Mediator complex. Distantly related ELL- and EAF-like genes were identified in S. pombe that encode Ell1/Eaf1 and can stimulate Pol II elongation in vitro. My thesis addresses two distinct projects, with overlapping motivations:

 First, to see whether S. pombe might provide a good model for functional studies of the Mediator and ELL/EAF interaction, I carried out a thorough proteomic analysis of S. pombe Mediator and defined several new subunits. My results were recently published as part of a collaborative structural analysis of S. pombe Mediator.

 Second, I used a combination of biochemical, genetic, and genomic approaches to characterize Ell1/Eaf1 function in fission yeast. Using mass spectrometry, I identified an uncharacterized sequence orphan, SPAC6G9.15c, that associates with both Ell1 and Eaf1 to form a ternary complex that, based on ChIP-seq localizes at genes with high RNA Pol II occupancy. I also performed an SGA screen for genes that genetically interact with ell1, eaf1, and SPAC6G9.15c and identified a set of overlapping genes that interact with all three, as well as others that interact only with ell1.

description: A scalar theory of gravity with a preferred reference frame is presented. It is insisted on the dynamics, which involves a (non-trivial) extension of Newton's second law, and on the new version (v2) with isotropic space metric. We display the energy conservation equation obtained with v2. Then the principles of the asymptotic post-Newtonian approximation are discussed in some detail. The results of its application to the motion of a small extended body in a weakly-gravitating system are given and discussed: the weak equivalence principle was violated in v1, due to its anisotropic space metric (as the standard Schwarzschild metric), but is valid with v2.

The interaction between cadmium and iron in marine phytoplankton
Creators: name: Lane, Erin Susan
Publisher: name: University of British Columbia
Year: 2011

description: This study examined the intracellular Cd content (Cd:C) of seven species of cultured phytoplankton under varying degrees of Fe-limitation. A significant increase in Cd:C ratios was observed for all species grown under Fe-limitation, with an average 2- fold increase in Cd quotas. The mechanism behind this increase in Cd quotas was further investigated in a model diatom, Thalassiosira oceanica. A significant interaction was found between Cd and inorganic Fe(II). Inorganic Fe(II) uptake rates by Fe-limited T. oceanica were reduced by 50% when Cd was present, while Cd uptake was inhibited 36% in the presence of Fe(II). Inorganic Fe(II) uptake rates were also 15 times faster in Fe-limited cultures than in Fe-replete cultures. Cadmium and Fe(II) appear to enter the cell through common non-specific divalent metal transporters that are up-regulated under Fe-limitation, thereby leading to enhanced Cd accumulation. In addition to the effect of Fe-limitation on Cd:C ratios of cultured phytoplankton, a species/phyla effect was observed. A greater than 65-fold difference in Cd:C ratios was also observed between species grown under identical Fe concentrations. Oceanic diatoms had the highest Cd quotas and naked pryrnesiophytes the lowest. The intracellular Cd requirements of cultured phytoplankton were compared to the Cd content of natural phytoplankton assemblages from Fe-replete and Fe-limited waters in the subarctic Pacific, as well as to a global dataset of particulate Cd:P0₄3- ratios in surface waters. The phytoplankton from the Fe-limited station had the highest Cd:C ratios, which was attributed to a combination of species composition and Fe limitation. The same trend was found in our global data with HNLC stations having higher particulate Cd: P0₄ 3- ratios than Fe-replete stations. The combined laboratory, field, and global dataset results suggest that deviations in surface water Cd:PO₄3- ratios can be explained by both changes in species composition well as Fe-limitation. We propose that the "kink" in the global dissolved Cd:PO₄3- relationship is a result of the export of Fe-limited diatoms with high intristic Cd:P0₄3- ratios in HNLC regions.

description: Experiments were conducted under controlled conditions to determine the effect of different ethanol concentrations on the initial growth of'Camelot' bell pepper. Plants in the two-true leaf stage were submersed for 2 minutes in either 0, 5, 10, 15 or 20% ethanol solution (v/v). Plant height, leaf area per plant, number of floral buds per plant and leaf and stem dry weight per plant were collected 40 days after treatment. Bell pepper plants had the highest values for all variables under study when solutions containing 10% ethanol were applied. In most cases, 20% solutions reduced variables studied at or below control levels.

For the finite time blow-up, two cases are discussed under the conditions $w_i\in L^1(\mathbb{R}^N)$ and $\int_{\mathbb{R}^N} w_i(x)\,dx>0$, $i=1,2$. Namely, if $σ>0$ or $γ>0$, we show that the (mild) solution $(u,v)$ to the considered system blows up in finite time, while if $σ,γ\in(-1,0)$, then a finite time blow-up occurs when $\frac{N}{2}< \max\left\{\frac{(σ+1)(pq-1)+p+1}{pq-1},\frac{(γ+1)(pq-1)+q+1}{pq-1}\right\}$. Moreover, if $\frac{N}{2}\geq \max\left\{\frac{(σ+1)(pq-1)+p+1}{pq-1},\frac{(γ+1)(pq-1)+q+1}{pq-1}\right\}$, $p>\fracσγ$ and $q>\fracγσ$, we show that the solution is global for suitable initial values and $w_i$, $i=1,2$.

description: We discuss the dynamics and thermodynamics of systems with long-range interactions. We contrast the microcanonical description of an isolated Hamiltonian system to the canonical description of a stochastically forced Brownian system. We show that the mean-field approximation is exact in a proper thermodynamic limit. The equilibrium distribution function is solution of an integrodifferential equation obtained from a static BBGKY-like hierarchy. It also optimizes a thermodynamical potential (entropy or free energy) under appropriate constraints. We discuss the kinetic theory of these systems. In the $N\to +\infty$ limit, a Hamiltonian system is described by the Vlasov equation. To order 1/N, the collision term of a homogeneous system has the form of the Lenard-Balescu operator. It reduces to the Landau operator when collective effects are neglected. We also consider the motion of a test particle in a bath of field particles and derive the general form of the Fokker-Planck equation. The diffusion coefficient is anisotropic and depends on the velocity of the test particle. This can lead to anomalous diffusion. For Brownian systems, in the $N\to +\infty$ limit, the kinetic equation is a non-local Kramers equation. In the strong friction limit $ξ\to +\infty$, or for large times $t\gg ξ^{-1}$, it reduces to a non-local Smoluchowski equation. We give explicit results for self-gravitating systems, two-dimensional vortices and for the HMF model. We also introduce a generalized class of stochastic processes and derive the corresponding generalized Fokker-Planck equations. We discuss how a notion of generalized thermodynamics can emerge in complex systems displaying anomalous diffusion.

title: Severe Hand Foot and Mouth Disease in Vietnamese Children: Clinical Features and Management Strategies
Creators: name: Phan, Tu Qui

description: Hand, Foot and Mouth Disease (HFMD) plays a major role in childhood morbidity and mortality in Vietnam and the Asia-Pacific region. The spectrum of severe disease and predictors for poor outcome are not well understood, and the evidence-base for management of hypertension in severe cases is lacking. In this thesis I describe the clinical features, their evolution over time, and the viral serotype/genotype findings, among 1272 HFMD cases admitted to PICU at the Hospital for Tropical Diseases (HTD), Ho Chi Minh City, during the the 2011-2012 Vietnam outbreak. Fever, skin rash, and myoclonic jerks happened in the early stage while the more severe features, including hypertension, tachypnea, irregular breathing, pulmonary edema and shock occurred after day 3. Most severe features were associated with EV-A71 infection rather than with Coxsackieviruses (CV). However having mouth ulcers without skin lesions was associated with CV infection. The C4 genogroup of EV-A71 was associated with more severe neurological involvement. Risk factors present within 24 hours of PICU admission that were associated with subsequent deterioration to severe outcome were skin lesions and tachypnea, while presence of mouth ulcers alone was protective. I also describe the development and execution of a randomized controlled trial of a novel treatment, MgSO4, for severe HFMD with hypertension secondary to ANS dysregulation. However, only 26 of the planned 190 patients were enrolled before the outbreak was controlled, and with this small number we found no evidence of benefit in this trial. In another approach, I assessed the efficacy of MgOS4 on severe hypertension among 33 patients treated with open-label MgSO4 compared to 12 patients of similar clinical severity who did not receive this intervention, and found a significant reduction in mean arterial pressure among the MgSO4 recipients. However, It is clear that with the small sample size, these data are insufficient to address the important question originally posed. Using our pre-prepared protocol as a basis, a much larger trial could be developed at short notice in the event of another outbreak, to properly evaluate whether MgSO4 has a role in controlling the blood pressure in severe HFMD.

description: Con la finalidad de conseguir métodos de protecciôn de tomate contra la penetration temprana de "moscas blancas" Bemisia tabaci (Genn.) (Homoptera: Aleyrodidae), vectores del Virus del Rizado Amarillo de la Hoja de Tomate (TYLCV), se evaluaron 9 métodos de protecciôn de semilleros, durante el periodo julio-septiembre de 1995. Se observô eue los tratamientos con Cobertura (mulch) de cascarilla de arroz, Cobertura de plâstico amarillo y plâstico color plateado tuvieron las poblaciones mâs altas de adultos de B. tabaci, mientras que las de los tratamientos del insecticida sistémico Imidacloprid, del Testigo y de dos tûneles de mallas (AntiVirus® y Avgol®) fiieron muy inferiores. Para la presencia de sintomas de geminivirosis, los tratamientos malla AntiVirus®, malla Avgol® y Barrera viva con sorgo fueron significativamente mâs bajos que los demâs tratamientos. En cuanto al efecto sobre el desarrollo de las plantas tomando como parâmetro la lloraciôn y fructification en los diferentes tratamientos, se observô que ésta fue mâs temprana en los tratamientos cobertura de plâstico amarillo, cobertura de plâstico plateado, testigo cobertura con cascarilla de arroz y banda amarilla pegante. Una cobertura de las plantas con mallas por 30, 45 ô 60 dias conlleva un atraso en el desarrollo. Se comprobô que la protecciôn de las plantas con mallas resultan en temperaturas mâs elevadas dentro de los canteros, con respecto a los demâs tratamientos.

description: We derive the distribution of the phantom dark matter in the eight classical dwarf galaxies surrounding the Milky Way, under the assumption that modified Newtonian dynamics (MOND) is the correct theory of gravity. According to their observed shape, we model the dwarfs as axisymmetric systems, rather than spherical systems, as usually assumed. In addition, as required by the assumption of the MOND framework, we realistically include the external gravitational field of the Milky Way and of the large-scale structure beyond the Local Group. For the dwarfs where the external field dominates over the internal gravitational field, the phantom dark matter has, from the star distribution, an offset of ~0.1-0.2 kpc, depending on the mass-to-light ratio adopted. This offset is a substantial fraction of the dwarf half-mass radius. For Sculptor and Fornax, where the internal and external gravitational fields are comparable, the phantom dark matter distribution appears disturbed with spikes at the locations where the two fields cancel each other; these features have little connection with the distribution of the stars within the dwarfs. Finally, we find that the external field due to the large-scale structure beyond the Local Group has a very minor effect. The features of the phantom dark matter we find represent a genuine prediction of MOND, and could thus falsify this theory of gravity in the version we adopt here if they are not observationally confirmed.

description: We report a numerical study of saddles properties of the potential energy landscape for soft spheres with different softness, i.e. different power n of the interparticle repulsive potential. We find that saddle-based quantities rescale into master curves once energies and temperatures are scaled by mode-coupling temperature T_MCT, confirming and generalizing previous findings obtained for Lennard-Jones like models.

description: The article is devoted to the rationale for the choice of financial indicators for the diagnosis of the financial condition of the enter-prise and determine the probability of their bankruptcy. In the context of a long economic crisis, which affected almost all enterprises of Ukraine, the issue of early diagnosis of the financial condition of enterprises and determining the probability of their bankruptcy is relevant. The most well-known in our time models for diagnosing the financial condition of the enterprise and determining the probability of their bankruptcy are not fully adequate in the specific conditions of the domestic economy. Therefore, it is important to select the most important indicators and give them priority in the relevant model. The task of the work is to test the theoretical studies on the selection and prioritization of financial indicators, which are planned to be used in the future to build models for the diagnosis of the financial con-dition of enterprises. The test is to assess the priority through the study of empirical data by means of factor and correlation analysis and comparison of empirical data studies with previous results of prioritization of financial indicators by the method of analysis of hierarchies and with the involvement of experts. It is shown that for the diagnosis of selected financial indicators are to be studied for multicollinearity. The financial indicators of the enterprises selected for the study were subjected to statistical analysis. The factor and correlation analy-sis of financial indicators on the basis of studies of financial statements of enterprises, revealed a weak mutual influence of indicators, which indicates their optimal choice. Factor analysis revealed the contribution of each of the financial indicators to the overall result. The financial indicators involved in the study can be used in the future to build neural network and fuzzy-logical models for assessing the probability of bankruptcy of enterprises. The research results can be aimed at building models for assessing the financial condition of the enterprise and the probability of their bankruptcy with the help of modern tools for modeling economic processes – fuzzy logic and neural networks – and checking the adequacy of the proposed models.

description: We study the effects of rotation on the quasi normal modes (QNMs) of a newly born proto neutron star (PNS) at different evolutionary stages, until it becomes a cold neutron star (NS). We use the Cowling approximation, neglecting spacetime perturbations, and consider different models of evolving PNS. The frequencies of the modes of a PNS are considerably lower than those of a cold NS, and are further lowered by rotation; consequently, if QNMs were excited in a sufficiently energetic process, they would radiate waves that could be more easily detectable by resonant-mass and interferometric detectors than those emitted by a cold NS. We find that for high rotation rates, some of the g-modes become unstable via the CFS instability; however, this instability is likely to be suppressed by competing mechanisms before emitting a significant amount of gravitational waves.

description: Using the quantum construction of the BV-BFV method for perturbative gauge theories, we show that the obstruction for quantizing a codimension 1 theory is given by the second cohomology group with respect to the boundary BRST charge. Moreover, we give an idea for the algebraic construction of codimension $k$ quantizations in terms of $\mathbb{E}_k$-algebras and higher shifted Poisson structures by formulating a higher version of the quantum master equation.
