Numerical Investigation of the Undrained Compression and Pull-Out Capacity of Suction Foundations in Clay
Authors: Du Jiaqing , Du Shouji , Shen Shuilong , Yin Zhenyu 
Published: October 2015

Abstract
This paper presents the results of three-dimensional finite difference analysis of suction foundations in uniform and non-uniform clays under undrained conditions. The Tresca criterion was used to simulate the stress-strain response. The bearing capacity of the foundations was investigated, with the degree of nonhomogeneity (kD/sum) of soil varying from 0 to 5, and the embedment depth being up to four times the foundation diameter. The end bearing capacity factor in compression and the reverse bearing capacity factor in tension were both calculated and were compared with each other under different foundation displacements. Numerical results showed that the ultimate bearing capacity factor can have the same value in cases of both compression and tension. The recommended ultimate bearing capacity factor is determined on the basis of the embedment ratio and displacement magnitude, and the displacement is not more than 30% of the foundation diameter. Finally, two equations are proposed to evaluate both the bearing capacity factor and the effective depth factor.

Abstract
Learning from the motion principle of quadrotor, a symmetric propeller AUV, which has small size and low velocity is designed. Compared with the AUV equipped with rudders, it has better maneuverability and manipulation at low velocity. According to the Newton-Euler method, the 6 DOF kinematic model and dynamic model of the propeller AUV are established. A stability controller that consists of 3 different PID controllers is designed. It makes the depth and attitude angle as trigger conditions, and the relevant controller is chosen in different moving process. The simulation experiments simulate ideal motion state and disturbed motion state, and experiments results show that the stability controller based on combined sections method can make the best of mature technology of PID, and meet the control requirements in different stages. It has a higher respond speed and accuracy, improving the stability of the propeller AUV under the disturbance of complex ocean currents.

Published: October 2015

Abstract
In this study numerical and analytical approaches were investigated in terms of accuracy of their results, practicality of solution and ability to reproduce the main features of the parametric roll phenomenon such as loss of stability and bifurcations in parametric roll motion analysis of ships. In general, single-degree-of-freedom analytical approach is based on reducing number of degrees of freedom from 3 to 1 by using the quasi-static Froude-Krylov assumption, incorporating heave and pitch effects by means of a time varying restoring moment. On the other hand, numerical approaches to motion of six and four degrees of freedom are based on three dimensional diffraction/radiation and potential flow theories. In summary, this paper reveals that analytical approaches are sufficiently adequate to obtain accurate practical results for this relatively complex phenomenon.

Abstract
The SatBałtyk (Satellite Monitoring of the Baltic Sea Environment) project is being realized in Poland by the SatBałtyk Scientific Consortium, specifically appointed for this purpose, which associates four scientific institutions: the Institute of Oceanology PAN in Sopot - coordinator of the project, the University of Gdańsk (Institute of Oceanography), the Pomeranian Academy in Słupsk (Institute of Physics) and the University of Szczecin (Institute of Marine Sciences). The project is aiming to prepare a technical infrastructure and set in motion operational procedures for the satellite monitoring of the Baltic Sea ecosystem. The main sources of input data for this system will be the results of systematic observations by metrological and environmental satellites such as TIROS N/NOAA, MSG (currently Meteosat 10), EOS/AQUA and Sentinel -1, 2, 3 (in the future). The system will deliver on a routine basis the variety of structural and functional properties of this sea, based on data provided by relevant satellites and supported by hydro-biological models. Among them: the solar radiation influx to the sea’s waters in various spectral intervals, energy balances of the short- and long-wave radiation at the Baltic Sea surface and in the upper layers of the atmosphere over the Baltic, sea surface temperature distribution, dynamic states of the water surface, concentrations of chlorophyll a and other phytoplankton pigments in the Baltic waters, spatial distributions of algal blooms, the occurrence of coastal upwelling events, and the characteristics of primary production of organic matter and photosynthetically released oxygen in the water and many others. The structure of the system and preliminary results will be presented.
Tryton Supercomputer Capabilities for Analysis of Massive Data Streams
Authors: Krawczyk Henryk , Nykiel Michał , Proficz Jerzy 
Published: October 2015

Abstract
The recently deployed supercomputer Tryton, located in the Academic Computer Center of Gdansk University of Technology, provides great means for massive parallel processing. Moreover, the status of the Center as one of the main network nodes in the PIONIER network enables the fast and reliable transfer of data produced by miscellaneous devices scattered in the area of the whole country. The typical examples of such data are streams containing radio-telescope and satellite observations. Their analysis, especially with real-time constraints, can be challenging and requires the usage of dedicated software components. We propose a solution for such parallel analysis using the supercomputer, supervised by the KASKADA platform, which with the conjunction with immerse 3D visualization techniques can be used to solve problems such as pulsar detection and chronometric or oil-spill simulation on the sea surface.

Published: October 2015

Abstract

Introduction. Studies often suggest hypoxemia is an important factor for sodium retention in chronic obstructive pulmonary disease (COPD), although hypercapnia is also associated with sodium retention in these patients. Hence, we have presented the major role of PaCO2 in edema due to COPD.

Method. COPD patients who were hospitalized due to exacerbation were enrolled in the study and divided into two groups: with and without edema. Exclusion criteria included primary hepatic diseases, nephrotic syndrome and other renal diseases, left heart failure, or using drugs that would interfere with these organs or endocrine function. Data were coded and analyzed by SPSS software. Arterial blood gas variables including bicarbonate, pH, and PaO2, PaCO2 and O2 saturation, and FEV1, FVC, FEV1/FVC were measured and compared between the groups.

Results. No significant difference was found between the averages of bicarbonate, pH, PaO2, O2 saturation, FEV1, FVC and FEV1/FVC in COPD in the two groups. PaCO2 levels were significantly higher in patients with edema, compared to those without edema (p = 0.05). A reverse and significant correlation between PaCo2 and FEV1 levels (p = 0.03) (r = −0.501) was observed in patients with edema.

Conclusion. This study suggests that hypercapnia is a major factor in causing edema in COPD patients compared to hypoxemia.

Abstract
Management of antithrombotic therapy in elderly patients with unstable atherothrombotic disease and increased risk of bleeding is a major clinical challenge. We report the case of a 79 year-old diabetic man with rheumatoid arthritis on both oral corticosteroids and NSAID therapy with mild renal dysfunction, who presented to our hospital because of disabling claudication. Prior to admission he had several episodes of TIA. He also had recurrent small rectal bleeding and mild anemia attributed to his long-standing hemorrhoid disease. Angiography showed a sub-occlusive left internal carotid artery stenosis associated with a significant LAD stenosis and complex peripheral artery disease. Cataclysmic bleeding and hemorrhagic shock occurred in the third day post admission. Withdrawal of all antithrombotic treatment, blood transfusion and emergency sigmoidectomy were performed for bleeding colonic diverticulosis. Subsequently antiplatelet therapy was reinitiated and the patient successfully underwent left carotid artery endarterectomy and LAD stenting. He was discharged from hospital on the 21st day post admission and is doing well at 24 months follow-up.

Abstract
A 78-year-old Caucasian man was admitted in the Department of Neurology for visual disturbances, started two days before. The next day the patient experienced headache, fever and gait disturbances. He had hypertension, diabetes mellitus, an ischemic stroke 13 years ago, longstanding seronegative rheumatoid arthritis (17 years), polynodular goiter, right ischio-pubian fracture and right femoral vein thrombosis a year ago due to a car accident, since he is treated with oral anticoagulants associated to antiaggregant, hypotensors, statin and oral antidiabetics. The neurologic examination had evidenced nuchal rigidity, left homonymous hemianopsia, left central facial palsy, ataxia of the inferior limbs with wide-based gait, achilean reflexes abolished bilaterally, bilaterally abolished plantar reflexes, ideomotor apraxia, dysarthria, hypoprosexia, and preserved consciousness patient. A non-contrast cerebral CT scan had shown right temporal and parieto-occipital intraparenchymatous hemorrhages, a right frontal sequelar lesion, multiple old lacunar infarcts, cortical atrophy. Laboratory findings included an inflammatory syndrome, absence of rheumatoid arthritis positive serology, normal coagulogram, an elevated proteinuria. The cerebral IRM performed on the seventh day of hospitalisation was suggestive for subacute right parietal hemorrhage, old cerebral infarction in the right anterior cerebral artery area, old lacunar infarcts and cerebral atrophy. The anticoagulant and antiaggregant treatment was stopped after a generalized tonic-clonic seizure occurred. Antiedematous, hypotensor, anticonvulsivant, beta-blocker, and symptomatic treatment was started, while the antidiabetic treatment was continued. All symptoms remitted. Arguments for amyloid angiopathy in our patient are previous non-cardioembolic ischemic stroke and a chronic inflammatory disease-rheumatoid arthritis in his personal medical history.

Abstract
Unfavorable light conditions in urban areas are one of the most important cause of inappropriate grass communities condition. The possibility to detect the plant stress caused by shade is an important element in shaping the environment. The answer to following questions: what is the ability to detect the stress caused by shade in chosen lawn varieties of Perennial ryegrass by using the chlorophyll a fluorescence (O-J-I-P test) and which of tested varieties has the best properties to create grasslands in reduced light conditions is the aim of this work. Two-factor experimental micro-plot was conducted with three varieties and three different shadowing variants. Chlorophyll a fluorescence measurements were provided and were compared to leaf density. Our results explored significant difference between selected varieties in the terms of their photosynthetic apparatus adaption to light conditions. During May, all tested varieties were characterized by the rise of all fluorescence curve points under lower light intensity. The largest changes under shade conditions were noticed for the variety ‘Taya’. During next months a declining trend of photosynthetic efficiency for this variety was observed. On the basis of our results, we assume that each variety has unique threshold and needs of light intensity.

Von Prag nach Jerusalem
Authors: Weiss Yfaat 
Published: October 2015

Vorspann
Das Vernichtungsprogramm des Dritten Reichs zielte nicht nur auf die Ermordung der europäischen Juden, sondern auch darauf, ihre Kultur auszulöschen. Es kam zu einem beispiellosen Raubzug im Deutschen Reich und allen seit 1938 besetzten Gebieten - einem Raubzug, der neue Sammlungen an Kunst, Handschriften, wertvollen Büchern oder liturgischen Gerätschaften in den Händen der Täter entstehen ließ. Die ursprünglichen Besitzer waren zumeist geflohen, gefangen oder tot. Yfaat Weiss zeichnet die politisch-juristische Debatte über den Umgang mit diesem oft erbenlosen Raubgut nach, das nach Auffassung prominenter Vertreter jüdischer Institutionen und Organisationen keinesfalls in deutschen Händen verbleiben sollte. An ausgewählten Beispielen wird deutlich, wie schwer die Pläne umzusetzen waren, in den Wirren der ersten Nachkriegsjahre geraubte Kulturgüter nach Jerusalem zu holen und dadurch nicht zuletzt ein Zeichen im konfliktreichen Prozess der Gründung des Staates Israel zu setzen.
Hitler in Vinnica
Authors: Hürter Johannes , Uhl Matthias 
Published: October 2015

Vorspann
Die Nerven lagen blank in Vinnica. Dort, in der Ukraine, hatte Adolf Hitler im Sommer 1942 sein Hauptquartier aufgeschlagen, und von dort aus musste er mitansehen, wie der zweite große Feldzug in der Sowjetunion, der Griff nach dem kaukasischen Öl, scheiterte. Als sich die deutsche Offensive im September 1942 endgültig festlief, schwanden die deutschen Erfolgsaussichten nahezu vollständig, bereits Monate vor der Niederlage in Stalingrad. Die Enttäuschung eskalierte in heftigen Schuldzuweisungen Hitlers an seine Generale. Bisher war man über diesen Konflikt nur aus der Sicht der Generalität informiert. Jetzt ist in einem russischen Archiv das Wortprotokoll einer vertraulichen Besprechung Hitlers mit Keitel aufgetaucht, das die Meinungen und Stimmungen des Diktators an der Peripetie des Kriegsjahrs 1942 unmittelbar wiedergibt.

AbstractRIG‐I is a well‐studied sensor of viral RNA that plays a key role in innate immunity. p97 regulates a variety of cellular events such as protein quality control, membrane reassembly, DNA repair, and the cell cycle. Here, we report a new role for p97 with Npl4‐Ufd1 as its cofactor in reducing antiviral innate immune responses by facilitating proteasomal degradation of RIG‐I. The p97 complex is able to directly bind both non‐ubiquitinated RIG‐I and the E3 ligase RNF125, promoting K48‐linked ubiquitination of RIG‐I at residue K181. Viral infection significantly strengthens the interaction between RIG‐I and the p97 complex by a conformational change of RIG‐I that exposes the CARDs and through K63‐linked ubiquitination of these CARDs. Disruption of the p97 complex enhances RIG‐I antiviral signaling. Consistently, administration of compounds targeting p97 ATPase activity was shown to inhibit viral replication and protect mice from vesicular stomatitis virus (VSV) infection. Overall, our study uncovered a previously unrecognized role for the p97 complex in protein ubiquitination and revealed the p97 complex as a potential drug target in antiviral therapy.

Para Colombia, el camino recorrido es de matices.

Los escenarios de educación superior serán el marco para observar las dinámicas sociales y culturales, ya que hay una gran tendencia a la feminización de la misma en todos los estamentos estudiantiles, docentes y directivos; sin embargo, el prejuicio de invisibilidad del discurso académico femenino permanece como constante frente a los poderes masculinos de la verdad del argumento racional.</p><p> </p><p align="justify"><strong>Palabras clave:</strong> Discurso femenino, participación femenina, género, educación-equidad</p>
