Making sense of circular economy
Creators: name: Blomsma, Fenna
Publisher: name: Imperial College London
Year: 2016

description: Calls have been voiced to change economic and industrial systems such that they align with sustainable development. One concept, circular economy, has emerged recently as a way to rethink waste and resource management. Within this research circular economy is defined as an umbrella concept that centres on the phenomenon of assessing a collection of resource life-extending strategies. This research explored how practitioners interpret the circular economy concept and how this influenced the enactment of waste and resource management, by use of a tool termed the Circularity Compass that was constructed for this purpose. A qualitative case study approach was followed, where 15 participants were interviewed, covering 23 innovation projects for 19 focal companies. The following seven insights stand out. Participants considered 1) materials and products and in particular parts or modules as playing important roles in establishing what resource life-extending strategies are possible; 2) other flows besides those directly related to the manufacturing of a product, such as material flows co-used with the product as well as energy and information flows, and frequently directed their attention at the infrastructure that facilitates these flows; 3) those strategies that allow for the flexible use of product capacity as valid interpretations of what constitutes a resource life-extending strategy; 4) resource life-extending strategies in sets of two or more, where they were frequently thought of as intimately related to each other; 5) addressing one or more barriers seen as inhibiting appropriate waste and resource management directly, whilst other barriers were subject to assumptions not further explored, or not acted upon in a number of cases; 6) various resource life-extending strategies as possibilities of a proposed intervention, without the need to completely resolve targeted routes; and, lastly, 7) participants experienced difficulties progressing the proposed solutions due to an inability to generate financial and political support.

The Bispectrum as a Signature of Gravitational Instability in Redshift-Space

description: The bispectrum provides a characteristic signature of gravitational instability that can be used to probe the Gaussianity of the initial conditions and the bias of the galaxy distribution. We study how this signature is affected by redshift distortions using perturbation theory and high-resolution numerical simulations. We obtain perturbative results for the multipole expansion of the redshift-space bispectrum which provide a natural way to break the degeneracy between bias and $Ω$ present in measurements of the redshift-space power spectrum. We propose a phenomenological model that incorporates the perturbative results and also describes the bispectrum in the transition to the non-linear regime. We stress the importance of non-linear effects and show that inaccurate treatment of these can lead to significant discrepancies in the determination of bias from galaxy redshift surveys. At small scales we find that the bispectrum monopole exhibits a strong configuration dependence that reflects the velocity dispersion of clusters. Therefore, the hierarchical model for the three-point function does not hold in redshift-space.

Measurement-device-independent and arbitrarily loss-tolerant verification of quantum steering

description: We propose a method to verify quantum steering for two qubit states with an arbitrary amount of null results when both the steering and steered parties cannot be trusted. We converted the steering inequality proposed in a recent article [Phys.~Rev.~X {\bf 2}, 031003 (2012)] to a corresponding measurement-device-independent steering criterion that depends on the heralding efficiency of the steering party, number of measurement settings, and imperfection of the state preparation. As a result, for a relative frequency of valid measurement outcomes $η_H$, the steering can be verified using a number of different measurement settings larger than $1/η_H$ and maximally entangled states. Furthermore, steerability is guaranteed as long as the measurement efficiency of the steered party is non-zero. Our result is useful for loss-tolerant and measurement-device-independent steering tasks.

Polarization of Astronomical Maser Radiation. III. Arbitrary Zeeman Splitting and Anisotropic Pumping
Creators: name: Elitzur, Moshe
Publisher: name: arXiv
Year: 1995
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: General solutions of the maser polarization problem are presented for arbitrary absorption coefficients. The results are used to calculate polarization for masers permeated by magnetic fields with arbitrary values of \xB, the ratio of Zeeman splitting to Doppler linewidth, and for anisotropic pumping. The $\xb \to 0$ limit of the magnetic solution reproduces the linear polarization derived in previous studies, which were always conducted at this unphysical limit. While terms of higher order in \xb\ have a negligible effect on the magnitude of $q$, they produce some major new results. In particular, the linear polarization is accompanied by circular polarization, proportional to \xb. Because \xb\ is proportional to the transition wavelength, the circular polarization of SiO masers should decrease with rotation quantum number, as observed. In the absence of theory for $\xb < 1$, previous estimates of magnetic fields from detected maser circular polarization had to rely on conjectures in this case and generally need to be revised downward. The fields in SiO masers are \about\ 2--10 G and were overestimated by a factor of 8. The OH maser regions around supergiants have fields of \about\ 0.1--0.5 mG, which were overestimated by factors of 10--100. The fields were properly estimated for OH/IR masers ($\la$ 0.1 mG) and \H2O masers in star-forming regions (\about\ 15--50 mG). Spurious solutions that required stability analysis for their removal in all previous studies are never reproduced here; in particular, there are no stationary physical solutions for propagation at $\sin^2θ< \third$, where $θ$ is the angle from the direction of the magnetic field, so such radiation is unpolarized. These spurious solutions can be identified as the \xb\ = 0 limits of non-physical solutions and they never arise at finite

The Applicability of the Astrometric Method in Determining the Physical Parameters of Gravitational Microlenses

description: In this paper, we investigate the applicability of the astrometric method to the determination of the lens parameters for gravitational microlensing events toward both the LMC and the Galactic bulge. For this analysis, we investigate the dependency of the astrometrically determined angular Einstein ring radius, $Δ(θ_{\rm E}/θ_{\rm E,0})$, on the lens parameters by testing various types of events. In addition, by computing $Δ(θ_{\rm E}/θ_{\rm E,0})$ for events with lensing parameters which are the most probable for a given lens mass under the standard models of Galactic matter density and velocity distributions, we determine the expected distribution of the uncertainties as a function of lens mass. From this study, we find that the values of the angular Einstein ring radius are expected to be measured with uncertainties $Δ(θ_{\rm E}/θ_{\rm E,0}) \lesssim 10%$ up to a lens mass of $M\sim 0.1 M_\odot$ for both Galactic disk-bulge and halo-LMC events with a moderate observational strategy. The uncertainties are relatively large for Galactic bulge-bulge self-lensing events, $Δ(θ_{\rm E}/θ_{\rm E,0}) \sim 25%$ for $M\sim 0.1 M_\odot$, but they can be substantially reduced by adopting more aggressive observational strategies. We also find that although astrometric observations can be performed for most photometrically detected Galactic bulge events, a significant fraction ($\sim 45%$) of LMC events cannot be astrometrically observed due to the faintness of their source stars.

Two-phase modelling of the rings in the RXTE two-color diagram of GRS 1915+105

description: The Galactic superluminal source GRS 1915+105 was found to experience a peculiar X-ray variability in a narrow count rate range of the PCA detector onboard RXTE. This can be seen as a ring-shaped pattern in the two-color diagram of count rates, where the hard hardness F(13-40keV)/F(2-13keV) is plotted against the soft hardness F(5-13keV)/F(2-5keV). The system runs one cycle with periods ranging between 50 - 100 s for different observations, one rotation in the 2-color diagram corresponding to the time between two contiguous maxima in the light curve. We model this behaviour successfully with the help of a self-consistent 2-phase thermal model where seed photons from an optically thick classical disk are Comptonized in a hot spherical corona surrounding the inner disk. In the model, changes of two parameters regulate the paths in the 2-color diagram: the black body temperature (Tin) of the inner disk and the Thomson optical depth multiplied by the electron temperature of the hot phase (tau*Te). These parameters oscillate with time but with a phase-shift between each other, causing the ring-shaped pattern. During the observation studied in more detail (20402-01-30-00), the inner disk radius varied with 97 s period between 20 - 35 km with an anticorrelation between the coronal and the mass accretion rate through the disk, possibly indicating a coupling between the disk and coronal accretion. During a typical cycle, the inner disk radius rapidly shrinked and returned more slowly back to the original larger value. In the rings we may see phenomena close to the black hole horizon under near Eddington accretion rates.

Increasing second dose Shingrix vaccine compliance in a veteran population using multiple strategies
Creators: name: Opara, Maureen
Publisher: name: No Publisher Supplied
Year: 2024

description: Purpose of Project: The purpose of the project was to measure the compliance rate with the second dose of Shingrix vaccination in a veteran population aged 50 and older using multiple strategic reminders, such as letters, phone calls, handouts, and posters.Methodology: This was a quality improvement project to increase the Shingrix vaccination compliance rate using multiple strategies. Chi-square was used to compare the observed and expected values of the Shingrix vaccine's second dose using letter-only reminders compared to multiple reminders within three months of the first dose. Design: A retrospective chart review was used to extract data to evaluate the effectiveness of multiple strategic reminders. Setting: Veteran Administration (VA) Patient Aligned Care Team (PACT) clinic. Study Population: Patients 50 and older who received their first dose of the Shingrix vaccine. Subject Recruitment: Patient charts were selected using the Computerized Patient Record System (CPRS) chart review. Sample: 150 charts were reviewed. Consent: This was a low-risk retrospective quality improvement project, with no consent required. Harm/Risk: There was no risk to patients. Interventions: A letter was sent to veterans who received the first dose of the Shingrix vaccine, posters were placed in the clinic area, and follow-up phone calls were made. Reminder letters were sent to those who did not return for the second dose. Data on the number of patients who returned with letters only and those who returned with multiple strategic reminders were collected. Results: There was no significant difference between the two groups (P=<.001%), denoted scientifically significant. Implications for Practice: Efforts should be made to ensure the Shingrix vaccine series are not interrupted.

description: The Cold Dark Matter (CDM) model has an elegant simplicitly which makes it very predictive, but when its parameters are fixed at their `canonical' values its predictions are in conflict with observational data. There is, however, much leeway in the initial conditions within the CDM framework. We advocate a re-examination of the CDM model, taking into account modest variation of parameters from their canonical values. We find that CDM models with $n=0.8$--0.9 and $h=0.45$--0.50 can fit the available data. Our ``best fit'' CDM model has $n=0.9$, $h=0.45$ and $C_2^{T}/C_2^{S}=0.7$. We discuss the current state of observations which could definitely rule out this model.

description: When transmitting polarised light through histological brain sections, different types of diattenuation (polarisation-dependent attenuation of light) can be observed: In some brain regions, the light is minimally attenuated when it is polarised parallel to the nerve fibres (referred to as D+), in others, it is maximally attenuated (referred to as D-). The underlying mechanisms of these effects and their relationship to tissue properties were so far unknown. Here, we demonstrate in experimental studies that diattenuation of both types D+ and D- can be observed in brain tissue samples from different species (rodent, monkey, and human) and that the strength and type of diattenuation depend on the nerve fibre orientations. By combining finite-difference time-domain simulations and analytical modelling, we explain the observed diattenuation effects and show that they are caused both by anisotropic absorption (dichroism) and by anisotropic light scattering. Our studies demonstrate that the diattenuation signal depends not only on the nerve fibre orientations but also on other brain tissue properties like tissue homogeneity, fibre size, and myelin sheath thickness. This allows to use the diattenuation signal to distinguish between brain regions with different tissue properties and establishes Diattenuation Imaging as a valuable imaging technique.

description: The term "ultraviolet (UV) burst" is introduced to describe small, intense, transient brightenings in ultraviolet images of solar active regions. We inventorize their properties and provide a definition based on image sequences in transition-region lines. Coronal signatures are rare, and most bursts are associated with small-scale, canceling opposite-polarity fields in the photosphere that occur in emerging flux regions, moving magnetic features in sunspot moats, and sunspot light bridges. We also compare UV bursts with similar transition-region phenomena found previously in solar ultraviolet spectrometry and with similar phenomena at optical wavelengths, in particular Ellerman bombs. Akin to the latter, UV bursts are probably small-scale magnetic reconnection events occurring in the low atmosphere, at photospheric and/or chromospheric heights. Their intense emission in lines with optically thin formation gives unique diagnostic opportunities for studying the physics of magnetic reconnection in the low solar atmosphere. This paper is a review report from an International Space Science Institute team that met in 2016-2017.

description: A major problem of medicine is the prevention, treatment and rehabilitation of patients with congenital mal-formations of the maxillofacial region. This is due to their frequency, the severity of anatomical and functional disorders, as well as the complexity of social adaptation of patients. Cleft lip and palate are highly common malformations with a significant variation of risk factors. The updating of epidemiological data in certain regions of Russia makes it possible to identify the dominant causal mechanisms of the occurrence of defects, to determine the necessary directions for improving preventive and diagnostic measures, treatment and tactics of dispensary supervision of patients. The analysis of the incidence of congenital malformations of the maxillofacial region in the city of Nizhny Novgorod and the Nizhny Novgorod region of Russia over the past 19 years has been carried out. The risk factors for the development of anoma-lies, the structure of morbidity, the type and nature of the therapeutic measures carried out were determined.

Testing and design of conventional and novel stainless steel hollow structural sections
Creators: name: Buchanan, Craig
Publisher: name: Imperial College London
Year: 2017

description: The topic of this thesis is the testing and design of conventionally formed and additive manufactured stainless steel hollow structural sections. Although design codes currently exist for stainless steel hollow structural elements, the provisions are based on limited structural data and therefore require further evaluation for their suitability, and are not intended to apply to additive manufactured elements. Focussing on conventionally formed circular hollow sections (CHS), the existing design provisions have been carefully reappraised based on a dataset of tests and finite element results generated in this study and existing tests collected from the literature. In total, 37 concentrically loaded column tests, 26 beam-column tests and 10 stub column tests have been undertaken on austenitic, duplex and ferritic stainless steel CHS. The experimental data has been supplemented with over 2400 finite element case studies. The reappraisal highlighted that there is additional capacity to be sought at the cross-section level for pure compression, bending and combined loading, and at the member level for beam-columns, but the current CHS flexural buckling provisions were found to be unconservative for certain global slenderness values. Based on these observations, revised design rules have been proposed. Additive manufactured sections, not currently covered by structural design standards, have also been investigated. An experimental programme consisting of 28 tensile coupon tests, 14 compressive coupon tests and 5 square hollow section (SHS) stub column tests has been undertaken. The initial results indicate general applicability of existing design standards to these new novel sections.

description: This study proposes that minimal surfaces not only minimize area but also minimize a natural entropy-density functional based on the mean curvature squared. By analyzing surfaces such as the catenoid, helicoid, and Enneper surface, we confirm that minimal surfaces achieve zero entropy-density while non-minimal surfaces (such as spheres, ellipsoids, and paraboloids) exhibit significant positive entropy-density. This offers a new structural variational principle for understanding minimal surfaces in differential geometry.
Reducing Transducer Equivalence to Register Automata Problems Solved by "Hilbert Method"

description: In the past decades, classical results from algebra, including Hilbert's Basis Theorem, had various applications in formal languages, including a proof of the Ehrenfeucht Conjecture, decidability of HDT0L sequence equivalence, and decidability of the equivalence problem for functional tree-to-string transducers. In this paper, we study the scope of the algebraic methods mentioned above, particularily as applied to the equivalence problem for register automata. We provide two results, one positive, one negative. The positive result is that equivalence is decidable for MSO transformations on unordered forests. The negative result comes from a try to extend this method to decide equivalence on macro tree transducers. We reduce macro tree transducers equivalence to an equivalence problem for some class of register automata naturally relevant to our method. We then prove this latter problem to be undecidable.
Numerical simulation of vertical intermittent flows
Creators: name: Galleni, Francesco
Publisher: name: Imperial College London
Year: 2017

description: The present research extends the application of the “slug capturing” technique, already extensively validated for the prediction of horizontal slug flow, to the case of vertical pipes. In this technique, the one-dimensional two fluid model is solved numerically in order to simulate mechanistically the growth and development of the structures which characterise the vertical intermittent flow, such as slugs and waves. In this work the technique is first successfully applied to the prediction of vertical slug flow: it is shown here that, when the appropriate correlation for the interfacial friction forces is used, the slug capturing technique is able to simulate correctly – even in vertical configurations - the complete evolution of the slugs and to predict their key characteristics with a notable accuracy when compared against experimental data. This represents certainly the most important achievement of this work. The one-dimensional two-fluid model is well known to be ill-posed and hence, as the mesh is refined, artificial instabilities may grow so as to render the simulation unreliable. For this reason, a Von Neumann analysis of the discretized form of the model is presented. It is shown that the discretization introduces a cut-off limit for short wavelengths, below which all the perturbations are damped. It is suggested here that this effect, for practical sizes of the mesh, is sufficient to stabilize the system. Furthermore, this work presents preliminary results of the application of the technique to churn flow. It is shown that, although the results may be considered promising, the model still needs development.

description: Six objects with broad emission lines and redshifts from 0.48 to 2.07 were discovered among 736 extragalactic objects in the Canada-France Redshift Survey (CFRS). Although the luminosities of half of the objects are such that they are in the Seyfert regime (M_B > -23), all would be designated as quasars in traditional surveys. Since the only selection criterion was that 17.5 < I_{AB} < 22.5, or approximately B < 23 (assuming a continuum power-law slope of alpha = -0.5), these quasars represent an unbiased, flux-limited sample. Although uncertain, the implied surface density, 200^{+120}_{-80} deg^{-2} is the highest yet measured, and is in good agreement with extrapolations from other faint surveys and the evolving luminosity function models of Boyle (1991). The distributions of the continuum properties, emission-line strengths, etc., of the quasars do not differ significantly from those of quasars selected by other means, and therefore they would have been detected in most traditional surveys. Three of the quasars may be associated with clusters or large structures of galaxies at z > 1.

The smooth ponomarenko dynamo
Creators: name: Wynne, James
Publisher: name: Imperial College London
Year: 2016

description: In this work, we study a class of continuous generalisations of the kinematic Ponomarenko Dynamo, in an annulus with perfectly conducting boundary conditions.\par We first consider the fundamentals of dynamo theory, deriving the governing equations and a general numerical code to find the growth rates for all modes and magnetic Reynolds numbers $R$. We concentrate on three types of flow fields: (a) flows which approximate the discontinuous Ponomarenko dynamo, (b) full solutions of the Navier Stokes driven by an axial pressure gradient and moving boundaries, and (c) flows where both the axial and azimuthal velocity components are powers of the cylindrical radius. Good agreement is found between the numerical results and the known asymptotic theory for large $R$. The smallest $R$-values permitting dynamo action are found, along with the values which gives rise to the fastest growing mode.

description: Neutron stars formed in Type II supernovae are likely to be initially obscured by late-time fallback. Although much of the late-time fallback is quickly accreted via neutrino cooling, some material remains on the neutron star, forming an atmosphere which slowly accretes through photon emission. In this paper, we derive structure equations of the fallback atmosphere and present results of one-dimensional simulations of that fallback. The atmosphere remaining after neutrino cooling becomes unimportant (less than the Compton Eddington limit) is only a fraction of the total mass accreted (10^-8 of the accreted mass or 10^-9 solar masses.) Recombined iron dominates the opacity in the outer regions leading to an opacity 1000-10,000 times higher than that of electron scattering alone. The resultant photon emission of the remnant atmosphere is limited to 1/1000th the Compton Eddington Luminosity. The late-time evolution of this system leads to the formation of a photon-driven wind from the accretion of the inner portion of the atmosphere, leaving, for most cases, a bare neutron star on timescales shorter than a year. The degenerate remnant of 1987a may not be a black hole. Instead, the fallback material may have already accreted or blown off in the accretion-driven wind. If the neutron star has either a low magnetic field or a low rotational spin frequency, we would not expect to see the neutron star remnant of 1987a.

description: We present the results of a near-infrared narrowband imaging survey of planetary nebulae. Objects were selected in a way that complements similar surveys done at visible and near-infrared wavelengths. No new detections of molecular hydrogen emission were made. The H2 is frequently found to be extended, except in young, visibly compact objects. Our results are consistent with the already determined correlation of H2 emission with planetary nebula morphological type. Filamentary and other kinds of structures are clearly resolved in many nebulae.

description: Currently, data are accumulating on the antioxidant properties of bilirubin and its protective role in various diseases. This review considers the dose-dependent effect of bilirubin on its cytoprotective and antioxidant properties, the relationship between the level of bilirubin and the pathophysiological manifestations of bronchial asthma, in the pathogenesis of which chronic inflammation induced by oxidative stress plays a significant role. The article also focuses on the potential therapeutic use of bilirubin in the treatment of bronchial asthma.

description: Assuming a simple form for the growth index gamma(z) depending on two parameters gamma_0 = gamma(z=0) and gamma_1 = gamma'(z=0), we show that these parameters can be constrained using background expansion data. We explore systematically the preferred region in this parameter space. Inside General Relativity we obtain that models with a quasi-static growth index and gamma_1 = -0.02 are favoured. We find further the lower bounds gamma_0 > 0.53 and gamma_1 > -0.15 for models inside GR. Models outside GR having the same background expansion as LCDM and arbitrary gamma(z) with gamma_0 = gamma_0^{LCDM}, satisfy G_{eff,0}>G for gamma_1 > gamma_1^{LCDM}, and G_{eff,0}

description: We apply and compare various Artificial Neural Network (ANN) and other algorithms for automatic morphological classification of galaxies. The ANNs are presented here mathematically, as non-linear extensions of conventional statistical methods in Astronomy. The methods are illustrated using different subsets Artificial Neural Network (ANN) and other algorithms for automatic morphological classification of galaxies. The ANNs are presented here mathematically, as non-linear extensions of conventional statistical methods in Astronomy. The methods are illustrated using different subsets from the ESO-LV catalogue, for which both machine parameters and human classification are available. The main methods we explore are: (i) Principal Component Analysis (PCA) which tells how independent and informative the input parameters are. (ii) Encoder Neural Network which allows us to find both linear (PCA-like) and non-linear combinations of the input, illustrating an example of unsupervised ANN. (iii) Supervised ANN (using the Backpropagation or Quasi-Newton algorithms) based on a training set for which the human classification is known. Here the output for previously unclassified galaxies can be interpreted as either a continuous (analog) output (e.g. $T$-type) or a Bayesian {\it a posteriori} probability for each class. Although the ESO-LV parameters are sub-optimal, the success of the ANN in reproducing the human classification is 2 $T$-type units, similar to the degree of agreement between two human experts who classify the same galaxy images on plate material. We also examine the aspects of ANN configurations, reproducibility, scaling of input parameters and redshift information.

Can a nurse driven early recognition system increase sepsis bundle compliance in the emergency room?
Creators: name: Crawford, Jessica
Publisher: name: No Publisher Supplied
Year: 2024

description: Purpose of Project: This DNP project wanted question if a nurse driven early recognition system could increase sepsis bundle compliance in the Emergency Department. Methodology: This project was implemented at suburban trauma level one emergency room for a four-week period. Twenty nurses were recruited and consented to carry out a sepsis check list, which served as early recognition protocol to identify those patients with potential sepsis. Data was extracted from the electronic medical record retrospectively and prospectively. After all data was abstracted, it was entered into a statistical software to determine if there was any significance in the results before the implementation and after the implementation. Results: There were five timeframe elements studied for this project, (a) the time to draw of initial lactate (b) time to draw of blood cultures, (c) time to the administration of intravenous fluids, (d), time to the administration of antibiotics, and (e) repeat of second lactate after fluid administration if initial lactate was over 2.0mmol/L. Out of the five timeframes studied from the pre implementation (n = 20), and the post implementation (n = 20), there was only a slight increase in the percentage of nurses who repeated a second lactate after the initial lactate was abnormally elevated. The percentage of nurses who repeated a lactate was 48% compliant in the pre implementation group and increased to 56% compliance in the post implementation group. Although there was an increase in the compliance, these findings were not significant (p<0.1). Implications for Practice: In the future, changes, and adjustments to this project along with the adherence to evidence practice guidelines could make a change in practice. As this project did show an increase in compliance, it does show that an early recognition system could help increase sepsis bundle compliance and make improvements in our future practice.

description: The effect of gas-discharge plasma radiation on the biochemical parameters of blood and urine of intact animals and animals with acute alcohol intoxication was investigated. Measurements of the content of medium-mass molecules (MMM), creatinine, urea, glucose, lactate and hemoglobin in the blood and 14 physicochemical indicators of the urine test were carried out. Acute alcohol intoxication (AAI) was simulated by intraperitoneal injection of 33% ethanol at a dose of LD50. The treatment was carried out by an experimental pulsed (10 Hz) device generating radiation of spark discharge plasma. It was revealed that exposure to plasma radiation does not lead to changes in the biochemical parameters of blood and urine of intact animals. In the model of AAI, the development of protein-creatininia, urobil-inogenuria, and an increase in the specific gravity of rat’s urine was observed. The total level of MMM and hemoglobin in the blood increased, lactic acidosis developed. After exposure to plasma radiation in animals with AAI, blood and urine parameters normalized, which is probably associated with the activation of the organism's adaptive and antioxidant reserves. Thus, the positive effect of spark discharge plasma radiation on the organism during acute ethanol intoxication has been shown.

description: This letter presents a new solution for the Tunguska event of June 30th, 1908. The solution has been obtained starting from seismic data, is in fair agreement with the observational evidence, and supports the asteroidal hypothesis for the origin of the Tunguska cosmic body. It is based on an improved model of the hypersonic flow around a small asteroid in the Earth's atmosphere.
