Nutation instability of spinning solid rocket motor spacecraft

Abstract The variation of mass, and moment of inertia of a spin-stabilized spacecraft leads to concern about the nutation instability. Here a careful analysis on the nutation instability is performed on a spacecraft propelled by solid rocket booster (SRB). The influences of specific solid propellant designs on transversal angular velocity are discussed. The results show that the typical SRB of End Burn suppresses the non-principal axial angular velocity. On the contrary, the frequently used SRB of Radial Burn could amplify the transversal angular velocity. The nutation instability caused by a design of Radial Burn could be remedied by the addition of End Burn at the same time based on the study of the combination design of both End Burn and Radial Burn. The analysis of the results proposes the design conception of how to control the nutation motion. The method is suitable to resolve the nutation instability of solid rocket motor with complex propellant patterns.
AIRPLANE SEAT WITH AN ADJUSTING DEVICE

The invention relates to an airplane seat (2) with an adjusting device (1), said airplane seat (2) comprising at least one adjustable seat element (3). The seat element (3) has an adjustable and a blocked state, and the seat element (3) can be adjusted only in the adjustable state by a manual application of force and/or by an application of force from a spring element (16) and/or by an application of force from the weight of parts of the airplane seat (2). The adjusting device (1) comprises at least one operating element (13) and at least one blocking element (11), said blocking element (11) being movable by means of the operating element (13) between a blocking position in which the seat element (3) is blocked and a neutral position in which the seat element (3) can be adjusted. The operating element (13) is an electronic and/or electric switch, and the blocking element (11) can be moved between the blocking position and the neutral position by means of an electrically operated actuator (15) which can be actuated by the switch using signals.
The analytic structure of conformal blocks and the generalized Wilson-Fisher fixed points

We describe in detail the method used in our previous work arXiv:1611.10344 to study the Wilson-Fisher critical points nearby generalized free CFTs, exploiting the analytic structure of conformal blocks as functions of the conformal dimension of the exchanged operator. Our method is equivalent to the mechanism of conformal multiplet recombination set up by null states. We compute, to the first non-trivial order in the $\epsilon$-expansion, the anomalous dimensions and the OPE coefficients of infinite classes of scalar local operators using just CFT data. We study single-scalar and $O(N)$-invariant theories, as well as theories with multiple deformations. When available we agree with older results, but we also produce a wealth of new ones. Unitarity and crossing symmetry are not used in our approach and we are able to apply our method to non-unitary theories as well. Some implications of our results for the study of the non-unitary theories containing partially conserved higher-spin currents are briefly mentioned.
Controlled singlet oxygen release photosensitizers in photodynamic therapy

Photodynamic therapy is a form of phototherapy which uses light-sensitive compounds (photosensitizers) that are exposed selectively to light, whereupon they become toxic to targeted malignant and other diseased cells. The photosensitizer creates a highly reactive singlet oxygen species which rapidly reacts with any nearby biomolecules leading to destructive reactions resulting in cell death through apoptosis or necrosis. However, prolonged exposure of tissue to light irradiation causes photosensitivity in patients’ skin. Side effects may include, pain, burning/stinging sensation, itchiness. This proposal aims to develop a conceptually new approach towards photodynamic therapy through an introduction of new type of photosensitizers and corresponding nanomaterials which are capable to generate singlet oxygen upon irradiation, store it by means of binding to special molecular subunits and slowly release singlet oxygen within tissue on a timescale from several hours to several days after light irradiation treatment. The application of such novel material will allow for increasing therapeutic effect and reduced side-effects with respect to conventional PDT due to shorter light treatment duration. Proof of concept will be attained by demonstration of delayed singlet oxygen formation in cancer cells after the light treatment using in vitro models. The project builds on the strengths of the applicant in organic chemistry, photophysics and material science and combines these with new training in biomedicine and drug development to open a new research direction and to enhance cross-European collaboration.
Aktuelle Liquordiagnostik bei erregerbedingten Krankheiten

Cerebrospinal fluid (CSF) analysis is of utmost importance to establish an early diagnosis of central nervous system (CNS) infections and to start appropriate therapy. The CSF white cell count, lactate concentration and total protein levels are usually available very quickly even from non-specialized laboratories and the combination of these parameters often provides sufficient information for decision-making in emergency cases. It is, however, not always possible to identify the underlying infective agent despite further CSF analyses, such as bacterial and fungal staining, evaluation of the blood-CSF barrier function, intrathecal immunoglobulin synthesis and oligoclonal IgG bands. Therefore, close communication between the laboratory and the clinician is an important prerequisite to specify additional pathogen-related diagnostic measures for successful confirmation of the diagnosis.
Evolutionary processes in calcifying organisms under future warming and biogeochemical implications

Future global warming will impact diverse marine ecosystems. Marine calcifiers play important roles as ecosystem engineers and in the carbon cycle. Two major groups of calcifying organisms are coccolithophores and Large Benthic Foraminifera (LBF). Coccolithophores are considered to be the most prominent carbonate producer in the ocean and also contribute about 50% of global primary production. LBF are major calcifiers in reef and other shallow marine environments. This group is usually characterised by algal symbiosis, making them contributors to primary production in tropical to subtropical areas. Understanding the response of these organisms is imperative as their ability to calcify and photosynthesis have major biogeochemical implications.
An important mechanism that allows organisms to cope with rapid climate or local environmental changes is physiological plasticity both within ontogenetic development and across generations. Transgenerational plasticity is specifically relevant when trying to understand the possible impacts of climate change since these anthropogenic changes will persist across generations. Hence, one of the main challenges of studying future effects on organisms is evaluating their adaptation potential through short laboratory experiments. To overcome this challenge, we will conduct multigenerational laboratory experiments simulating adaptation under future warming scenarios and estimate predicted changes in calcification and photosynthesis. Then, we will investigate carbonate shells from warm intervals in the geological record as a field experiment of extreme warmth under natural conditions. This will validate or highlight the gaps between experimental results and adaptation under natural conditions. Our results will indicate how adaptation will mitigate the response of coccolithophores and LBF to ocean warming and provide a realistic prediction of the biological effect of the organic pump versus the carbonate counter pump on oceanic pCO2.
Simulating Concurrent Behaviors with Worst-Case Cost Bounds

Modern software systems are increasingly being developed for deployment on a range of architectures. For this purpose, it is interesting to capture aspects of low-level deployment concerns in high-level modeling languages. In this paper, an executable object-oriented modeling language is extended with resource-restricted deployment components. To analyze model behavior a formal methodology is proposed to assess resource consumption, which balances the scalability of the method and the reliability of the obtained results. The approach applies to a general notion of resource, including traditional cost measures (e.g., time, memory) as well as concurrency-related measures (e.g., requests to a server, spawned tasks). The main idea of our approach is to combine reliable (but expensive) worst-case cost analysis of statically predictable parts of the model with fast (but inherently incomplete) simulations of the concurrent aspects in order to avoid the state-space explosion. The approach is illustrated by the analysis of memory consumption.
Molecular additive manufacturing through dna nanotechnology

In the last decades, DNA nanotechnology has been established as a robust method for the production of static, large two- and three-dimensional structures as well as dynamic systems based on the interaction of multiple small strands through strand displacement.  In the proposed project, Dr. Erik Benson will join Professor Turberfield’s group to develop the first demonstration of atomically precise manufacturing based on DNA nanotechnology. In his Ph.D. studies, Erik developed methods for the design of wireframe DNA nanostructures and used several experimental techniques to study their assembly. He will combine these skills with Professor Turberfield’s expertise in DNA nanomachines and dynamic DNA toehold systems to develop a first-generation molecular printer. The printer will be constructed by DNA origami, and consist of a guide rail that host a sliding write head whose movements are externally controlled by the introduction of DNA strands. The addition of activator strands will trigger a DNA hybridization catalyst placed at the tip of the write head, causing it to modify the target surface at the precisely determined positions. The principles developed in this project can be expanded into two and three dimensions by the connection of multiple linear motors. The development of robust, externally controlled linear motion at the nanoscale can also find application in other fields including nano-manipulation, biophysics, and controlled catalysis.
The Effects of Aerobic Exercise Capacity on Free Oxygen Radical in Blood during Submaximal Exercise in Rowing Ergometer

The purposes of this study were to examine the effects of aerobic exercise capacity on free oxygen radicals in blood(FORB) during submaximal exercise in rowing ergometer and as for study purposes, a set of experiments were conducted using one group of 6 rowing players(RP) and the other group of 6 non rowing players(NRP) at the maximum heart rate reserve(HRR) 85~90% exercise intensity. Oxygen free radical was sampled 5 times including a rest period(ARP), immediate after exercise(IAE), 10 minutes after exercise(10MAE), 20 minutes after exercise(20MAE) and 30 minutes after exercise(30MAE). Accordingly, following findings were derived from current study. The effects of interaction between groups and times were significant in oxygen free radical(p
Iterative linearized density matrix propagation for modeling coherent excitation energy transfer in photosynthetic light harvesting

Rather than incoherent hopping between chromophores, experimental evidence suggests that the excitation energy transfer in some biological light harvesting systems initially occurs coherently, and involves coherent superposition states in which excitation spreads over multiple chromophores separated by several nanometers. Treating such delocalized coherent superposition states in the presence of decoherence and dissipation arising from coupling to an environment is a significant challenge for conventional theoretical tools that either use a perturbative approach or make the Markovian approximation. In this paper, we extend the recently developed iterative linearized density matrix (ILDM) propagation scheme [E. R. Dunkel et al., J. Chem. Phys. 129, 114106 (2008)] to study coherent excitation energy transfer in a model of the Fenna-Matthews-Olsen light harvesting complex from green sulfur bacteria. This approach is nonperturbative and uses a discrete path integral description employing a short time approximation to the density matrix propagator that accounts for interference between forward and backward paths of the quantum excitonic system while linearizing the phase in the difference between the forward and backward paths of the environmental degrees of freedom resulting in a classical-like treatment of these variables. The approach avoids making the Markovian approximation and we demonstrate that it successfully describes the coherent beating of the site populations on different chromophores and gives good agreement with other methods that have been developed recently for going beyond the usual approximations, thus providing a new reliable theoretical tool to study coherent exciton transfer in light harvesting systems. We conclude with a discussion of decoherence in independent bilinearly coupled harmonic chromophore baths. The ILDM propagation approach in principle can be applied to more general descriptions of the environment.
Infrastructuring time in smart urbanism and urban transitions

The agenda set by climate change is urgent and accelerating, and cities are at the forefront to respond to climate change effects, to harness the resources for sustainable transitions and to adopt long-term policies and strategies for viable urban futures by 2030-2050. At the same time, existing networked data infrastructures allow the everyday management of cities (e.g. mobility, energy, water) and also interact with the efforts to achieve the climate targets. Yet, most recent scientific evidence shows that the sustainability efforts are jeopardised by existing infrastructures and a further effort is needed already by 2030 to stop irreversible damage from climate change. Subsequently, cities need to revise their climate plans, anticipating their actions and aligning their sustainability goals to the new scenarios. The tensions between the urgent agenda of climate change, the testing of sustainable urban futures and the actual ICT infrastructures already in place for urban management produce multiple temporal interferences that influence the paths towards sustainability. Through INFRATIME, I will develop an innovative approach to understand the combined temporality and rhythm of urban transitions and smart urbanism. In so doing, I intend to offer relevant insights to better re-temporalize urban transformations to the climate change agenda. The partnership between the University of Bologna (IT) as Beneficiary and the University of Tokyo (JP) as Third Country organisation, including the planned inter-sectoral secondment in Nordregio (SE), will offer the ideal platform to pursue the research objectives. The Fellowship will thus ensure international, intersectoral and interdisciplinary training and supervision at the highest standards, allowing me to deliver scientific excellence, to increase my employability across academic and non-academic sectors in a European and global context, and ultimately achieve a leading position in the field of sustainable smart urbanism.

Effects of surface tension on axisymmetric Hertzian contact problem

Abstract Surface tension plays an important role in micro/nanosized contact problems. Based on the solution of a point force acting on a half plane with surface tension, we consider the axisymmetric contact between a rigid sphere and an elastic half space. It is found that when the contact radius is comparable with the ratio of surface tension to elastic modulus, surface tension significantly affects the pressure distribution on the contact region. Compared to the classical Hertzian contact solution, the existence of surface tension decreases the displacements on the half plane and yields continuous slopes of normal stress and displacements across the contact fringe. In addition, the present model predicts the increase of hardness as the radius of indenter decreasing. This study is helpful to characterize and measure the mechanical properties of soft materials or biomaterials through micro-indentation.
Natural rubber with low heat generation achieved by the inclusion of boron carbide

Natural rubber with low heat generation was prepared by the inclusion of boron carbide (B4C). Tensile testing, scanning electron microscopy (SEM), dynamic mechanical analysis, and thermal constant analysis were performed. The results show that a slight deterioration of tensile strength only occurred at a high volume content (>20 vol %). The thermal conductivity increased for the formation of well-maintained B4C thermal conductive pathways. SEM images and theoretical analysis demonstrated that the specific area of B4C was small and the interfacial activity was low. Infrared thermal images taken by the infrared camera proved the low heat generation of the composites, which originated from the high thermal conductivity and the weak interface. © 2010 Wiley Periodicals, Inc.

Green Infrastructure Network

Biodiversity conservation policies have traditionally been developed and implemented within the nature conservation sector, and local and regional authorities are mainly responsible for implementing the policies and achieving their objectives. However, this presents the authorities with a range of challenges:
– many other land uses are increasing in extent and intensity
– much of the biodiversity outside Natura 2000 sites is subject to less strict or no formal protection
– conserving biodiversity in the long term requires the maintenance of ecosystem functions over wide areas
– climate change will lead to shifts in species populations, but the locations of existing protected areas are fixed.
Responding to these challenges has inspired the development of new approaches that aim to conserve biodiversity and maintain ecosystem services across the wider countryside but which are framed in close cooperation with other policy measures, such as agriculture, urban development, transport, re-
creation and climate change adaptation. These approaches are becoming known as “green infrastructure”. The concept has also been recognised by the European Commission, which has organised 2 meetings on the topic and is now developing a green infrastructure strategy (due 2011).

In order to learn from and apply this experience, a team of 12 partners has been formed: Flevoland Province (NL), Barcelona Province (ES), Fingal County (IE), Plovdiv Regional Development Agency (BG), Azores Regional Government (PT), Nicosia Development Agency (CY), Emilia-Romagna Region (IT), Ghajnsielem Municipality (MT), Valencia Region (ES), the Regional Environmental Center for Central and Eastern Europe (HU), the MEPRD (LV) and Stara Zagora Regional Economic Development Agency (BG).
The project’s main objective is to strengthen the development and implementation of green infrastructure in EU regions. This will be achieved through exchanging and disseminating expertise, experience and
best practices between the partners, tackling both general elements (analytical methodologies and policy development and implementation) and its development and implementation in 4 specific fields (in urbanised areas, in natural areas, in relation to rural land uses and to adapt to climate change). In addition, 3 types of best practice will be transferred to 6 partners (analytical methodologies, developing and implementing green infrastructure in urbanised regions and developing and implementing green infrastructure policies). The activities will produce a Green Infrastructure Action Toolkit for wider dissemination.

The durability of the results will be ensured through the best practices transferred, actions agreed in 12 implementation plans and the establishment of a permanent facility for the exchange, dissemination and transfer of experience, expertise and best practices between green infrastructure stakeholders across Europe: the European Green Infrastructure Knowledge Network.

The problem of massive emissions of carbon dioxide (CO2) from the burning of fossil fuels and related climatic impact have become major environmental, scientific and institutional issues worldwide. Long-term sustainability of the atmosphere requires a drastic decrease in CO2 emissions and an efficient energy strategy. Against growing energy consumption in the Mediterranean area, GR.ENE.CO project aims to reduce greenhouse gas emissions and to improve energy efficiency by adopting renewable energy as main power source at farm level. This will be reached through the implementation of several forms of renewable energy - biofuel, biomass, solar, wind and hydro power - in farms settled in the involved target areas: Sarcidano and Barbagia of Seulo (Italy), South Lebanon, Al Iskandanyah and Al Buhayrah territories (Egypt). _x000D_
