description: The interplay between crystallinity and superfluidity is of great fundamental and technological interest in condensed matter settings. In particular, electronic quantum liquid crystallinity arises in the non-Fermi liquid, pseudogap regime neighboring a cuprate's unconventional superconducting phase. While the techniques of ultracold atomic physics and quantum optics have enabled explorations of the strongly correlated, many-body physics inherent in, e.g., the Hubbard model, lacking has been the ability to create a quantum degenerate Fermi gas with interparticle interactions---such as the strong dipole-dipole interaction---capable of inducing analogs to electronic quantum liquid crystals. We report the first quantum degenerate dipolar Fermi gas, the realization of which opens a new frontier for exploring strongly correlated physics and, in particular, the quantum melting of smectics in the pristine environment provided by the ultracold atomic physics setting. A quantum degenerate Fermi gas of the most magnetic atom 161Dy is produced by laser cooling to 10 uK before sympathetically cooling with ultracold, bosonic 162Dy. The temperature of the spin-polarized 161Dy is a factor T/TF=0.2 below the Fermi temperature TF=300 nK. The co-trapped 162Dy concomitantly cools to approximately Tc for Bose-Einstein condensation, thus realizing a novel, nearly quantum degenerate dipolar Bose-Fermi gas mixture.

description: Many modifications of gravity introduce new scalar degrees of freedom, and in such theories matter fields typically couple to an effective metric that depends on both the true metric of spacetime and on the scalar field and its derivatives. Scalar field contributions to the effective metric can be classified as conformal and disformal. Disformal terms introduce gradient couplings between scalar fields and the energy momentum tensor of other matter fields, and cannot be constrained by fifth force experiments because the effects of these terms are trivial around static non-relativistic sources. The use of high-precision, low-energy photon experiments to search for conformally coupled scalar fields, called axion-like particles, is well known. In this article we show that these experiments are also constraining for disformal scalar field theories, and are particularly important because of the difficulty of constraining these couplings with other laboratory experiments.

title: Asphaltene deposition simulation in porous media during CO₂ injection using Lattice Boltzmann Method
Creators: name: Eskandari, Navid
Publisher: name: Memorial University of Newfoundland
Year: 2020

description: Carbon dioxide (CO₂) injection in oil reservoirs is a potential means of Enhanced Oil Recovery (EOR) and reducing greenhouse gas. Change in the thermodynamic condition and composition due to the CO₂ injection process may trigger the asphaltene precipitation and deposition which directly affects the efficiency of the EOR process. Predicting the possibility of the asphaltene issue under different operating conditions can help the oil industry for better process design, handle the potential operational problems and estimate the production cost. In spite of, the existence of different modeling approaches based on conventional numerical methods, the lack of a flexible and more comprehensive modeling approach is inevitable. The new and advanced numerical method, called the Lattice Boltzmann Method (LBM) covers the limitations of the conventional numerical methods in dealing with complex boundary conditions and incorporating the microscopic interactions. This study is aiming at the modeling of the Asphaltene deposition, and it’s effect on the fluid flow in porous media during an immiscible injection of CO₂ with applying the LBM as the main simulator engine that gets fed by the given phase behavior to take the asphaltene deposition into account as well. Porosity and CO₂ injection velocity are the changing factors in this study. Applying the same condition on two mediums, it has been seen that the recovery factor is 22.5% higher and deposited asphaltene is 2.56% lower in a more porous medium that is attributed to uniform pore size distribution and higher absolute permeability of the more porous case. Furthermore, the fingering phenomena seem to be high in a less porous medium which causes an early breakthrough. Studies on the CO₂ injection velocity effect showed that by increasing CO₂ injection velocity by 2 times and 3 times, the recovery factor increases 4% and decreases 6%, respectively. A decrease in recovery factor is attributed to the asphaltene deposition at which the deposited asphaltene is two times higher at injection velocity of 3
The Marian Dimension of Mother Maria's Orthodox Social Christianity

description: “Mother Maria,” has in recent years become an exemplar of modern Orthodox social engagement. Often hailed as Orthodoxy’s Dorothy Day, Skobtsova is known for the network of shelters, soup kitchens and medical facilities she opened from impoverished Russian émigrés in Paris during the 1930s. Perhaps her most radical work was in the French Resistance movement, where her assistance to French Jews led to her arrest by the Nazis and deportation to the Ravensbruck concentration camp. Many have read about Mother Maria’s dramatic life and times in the excellent biography by the priest and Slavist Sergei Hackel, whose, Pearl of Great Price: The Life of Mother Maria Skobtsova has been translated into many languages and was republished numerous times since its first appearance in 1965.

description: We report the successful imaging of flux vortices in single crystal MgB2 using transmission electron microscopy. The specimen was thinned to electron transparency (350 nm thickness) by focussed ion beam milling. An artefact of the thinning process was the production of longitudinal thickness undulations of height 1-2 nm in the sample which acted as pinning sites due to the energy required for the vortices to cross them. These had a profound effect on the patterns of vortex order observed which we examine here. Supplementary information can be downloaded from http://www-hrem.msm.cam.ac.uk/people/loudon/#publications

The discussion of the vortex-free region near the sample edge has been revised in response to referees' comments. Changes have been made to clarify that the specimen thickness is 250nm parallel to the c-axis but 350nm parallel to the electron beam

description: Background: Recent advances in 3D imaging technologies provide novel insights to researchers and reveal finer and more detail of examined specimen, especially in the biomedical domain, but also impose huge challenges regarding scalability for automated analysis algorithms due to rapidly increasing dataset sizes. In particular, existing research towards automated vessel network analysis does not always consider memory requirements of proposed algorithms and often generates a large number of spurious branches for structures consisting of many voxels. Additionally, very often these algorithms have further restrictions such as the limitation to tree topologies or relying on the properties of specific image modalities. Results: We propose a scalable iterative pipeline (in terms of computational cost, required main memory and robustness) that extracts an annotated abstract graph representation from the foreground segmentation of vessel networks of arbitrary topology and vessel shape. The novel iterative refinement process is controlled by a single, dimensionless, a-priori determinable parameter. Conclusions: We are able to, for the first time, analyze the topology of volumes of roughly 1 TB on commodity hardware, using the proposed pipeline. We demonstrate improved robustness in terms of surface noise, vessel shape deviation and anisotropic resolution compared to the state of the art. An implementation of the presented pipeline is publicly available in version 5.1 of the volume rendering and processing engine Voreen.

description: About 35 million acres not being cultivated have high potential for crop use and 117 million more have medium potential, according to the 1982 National Resources Inventory (NRI) conducted by the U.S. Department of Agriculture. Converted high potential land would increase cropland area by 8 percent over the 421 million cropland acres inventoried in 1982. The cropland base would increase 36 percent if both high and medium potential land were converted, but soil erosion could increase by just over 1 billion tons annually, nearly 20 percent above 1982. If only high potential lands were converted, the erosion increase could be only about 4 percent. Less favorable cost/price relationships for crop production since 1982, several provisions in the 1985 farm act, and change in the U.S. tax code will all tend to discourage conversions.

description: Die Arbeit zielt auf die Identifizierung von Chancen und Herausforderungen, die sich für die Gestaltung einer gesundheitsförderlichen Kita aus Sicht von Müttern mit unterschiedlichem Sozialstatus ergeben. Es handelt sich bei der Arbeit um eine Sekundäranalyse. 121 Interviews konnten in die qualitative Inhaltsanalyse nach Mayring einbezogen werden. Die Kategorien wurden sowohl theoriegeleitet deduktiv gebildet als auch im Kodierprozess induktiv ergänzt. Die Ergebnisse unterstreichen das hohe Potenzial des Kita-Settings für die Gesundheitsförderung und zeigen, dass Mütter sowohl Bedarfe an die Kita adressieren als auch die sich ergebenden Unterstützungs- und Vermittlungschancen schätzen. Allerdings verweisen die Ergebnisse auf eine ungleiche Verteilung der personalen sowie sozialen Ressourcen und Bewältigungsstrategien und daraus resultierende differente Bedarfe. Gesundheitsförderung im Setting Kita muss zunächst auf der strukturellen Ebene ansetzen und eine machtsensible und vorurteilsbewusste Ausgestaltung der interaktionalen Ebene sowie die Initiierung diversitätssensibler Maßnahmen und Angebote sicherstellen.
description: The thesis aims at identifying opportunities and challenges in the design of a health-promoting Kita from the point of view of mothers with a differing socio-economic status. The thesis is a secondary analysis.121 interviews were included in the qualitative content analysis according to Mayring. The categories were derived both deductively based on the theory and inductively based on the data. The results underline the great potential of day-care centers for health promotion and show that mothers address their needs to the day-care professionals as well as appreciate the opportunities for encouragement and mediation. The results, however, show an uneven distribution of personal and social resources and coping strategies amongst mothers, resulting in heterogeneous needs. First of all, the promotion of health in day-care centers must start at the structural level and ensure a power and prejudice-conscious organization of the interactional level as well as the initiation of diversity-sensitive measures.

description: Combining multiple estimators to obtain a more accurate final result is a well-known technique in statistics. In the domain of speech recognition, there are many ways in which this general principle can be applied. We have looked at several ways for combining the information from different feature representations, and used these results in the best-performing system in last year's Aurora evaluation: Our entry combined feature streams after the acoustic classification stage, then used a combination of neural networks and Gaussian mixtures for more accurate modeling. These and other approaches to combination are described and compared, and some more general questions arising from the combination of information streams are considered.

description: We investigate experimentally the number statistics of a mesoscopic ensemble of cold atoms in a microscopic dipole trap loaded from a magneto-optical trap, and find that the atom number fluctuations are reduced with respect to a Poisson distribution due to light-assisted two-body collisions. For numbers of atoms N>2, we measure a reduction factor (Fano factor) of 0.72+/-0.07, which differs from 1 by more than 4 standard deviations. We analyze this fact by a general stochastic model describing the competition between the loading of the trap from a reservoir of cold atoms and multi-atom losses, which leads to a master equation. Applied to our experimental regime, this model indicates an asymptotic value of 3/4 for the Fano factor at large N and in steady state. We thus show that we have reached the ultimate level of reduction in number fluctuations in our system.

title: Can we stop learning safety by accident?
Creators: name: Pike, Howard
Publisher: name: Memorial University of Newfoundland
Year: 2020

description: The question has been asked in many forums, why are major accidents still occurring? Awareness is an important basic learning factor to properly manage the lessons to be learned from major accidents. Over time, the recommendations made following an accident may be forgotten, procedures allowed to lapse, changes are made to equipment and the accident is just waiting to happen again. The memory within an organization that should help to prevent process safety accidents decays thus allowing accidents to repeat. It has been 38 years since the loss of all 84 crew members on the Ocean Ranger, the largest mobile offshore drilling unit of its day. At 1:10 a.m. EST on February 15, 1982, the Ocean Ranger’s crew sent a mayday call and abandoned the rig at 1:30 a.m. No one survived. There were no eye witnesses to tell what happened. Investigators were left with some technical evidence and the testimony from others. While the investigation report and recommendations from a Royal Commission into the Ocean Ranger tragedy changed the offshore safety regime of the time, can we learn more by re-examining the past? Can we stop learning safety by accident?
 Safety and environmental risk go hand in hand with industrial development. However, it is unclear whether there is a linear or nonlinear relationship between risk and industrial development. Perhaps, it is case dependent. Some industrial endeavors such as offshore development, activities in a harsher environment, or development requiring new technologies (untested and untrusted technologies) may pose a higher risk (nonlinear) than more conventional industrial development activities (e.g., petroleum refineries, petrochemical plants, pipeline transportation, and the like). Public perception plays a critical role in defining the risk versus development relationship. The public perception of risk is dependent on awareness and understanding of potential hazards and their likelihood of occurrence, and most importantly, effective communication of these along with the associated uncertainty. Public awareness can have a profound effect on the development of public policy, which in many cases is driven more by perception rather than by sound science. Two commonly used concepts of policy and decision-making will be investigated, the Precautionary Principle (PP) and As Low As Reasonably Practicable (ALARP). A clearer understanding of both approaches with an illustrative example will be provided. A process to help readers understand where and when PP versus ALARP would be most applicable is proposed.

description: The extension complexity of a polytope $P$ is the smallest integer $k$ such that $P$ is the projection of a polytope $Q$ with $k$ facets. We study the extension complexity of $n$-gons in the plane. First, we give a new proof that the extension complexity of regular $n$-gons is $O(\log n)$, a result originating from work by Ben-Tal and Nemirovski (2001). Our proof easily generalizes to other permutahedra and simplifies proofs of recent results by Goemans (2009), and Kaibel and Pashkovich (2011). Second, we prove a lower bound of $\sqrt{2n}$ on the extension complexity of generic $n$-gons. Finally, we prove that there exist $n$-gons whose vertices lie on a $O(n) \times O(n^2)$ integer grid with extension complexity $Ω(\sqrt{n}/\sqrt{\log n})$.

Charity and the Two Economies

description: A Christian will recognize that along with this usage of the term ‘charity’ there is a specifically Christian one of wider scope that refers to the supreme virtue that is synonymous with love, pity, or compassion in English, agape in Koine Greek, caritas in Latin, pieta in Italian. Though wider in scope, this sense of the term does not seem to be any more closely connected with economy; probably, the point of contact between charity in this sense and economy will be thought to pass through the narrower sense of charity as almsgiving. This is a mistake. And it is here my purpose to highlight and correct it in a way that I hope will make a special appeal to Orthodox Christians.

description: The use of motorcycles in commercial transportation is increasing due to its comfortable use in congested traffic conditions and the ease of parking on narrow streets. Motorcycle couriers are among the important members of the delivery industry. The race against time and delivering on time bring along many problems. This study aims to examine the relationships between perceived organizational support, colleague value and stress in motor courier employees. Within the scope of the study, 151 motorcycle couriers working in the delivery sector were selected. The study was carried out in the period of June-November 2022. In addition to 15 questions including demographic characteristics with the one-to-one interview method, Spielberger’s State and Trait Anxiety Scale, The Perceived Organizational Support Scale and The Coworker Support Scale were applied with the one-to-one interview method. The average age of the 151 couriers included in the study was 29.10 ± 7.01; the working year was 3.26 ± 3.39; the average number of daily trips was 36.47 ± 17.37; the average delivery time was 16.54 ± 10.10 in minutes (median 15); and the average weight of the cargo was 4.94 ± 5.51 (kg) (median: 3.50). The prevalence of occupational accidents in the last year has been 43.3% (n = 61). Examining the causes of the prevalence of accident among the study population, it was found that motorcycle overturning was 20 (32.8%); vehicle hitting the motorcycle was 26 (42.6%); motorcycle hitting the vehicle was 15 (24.6%). When the factors affecting the perceived organizational support were examined, it was found that those with a colleague social support score above 18 were more likely to have an organizational perception score above 80 (95% CI 1.001-4.843) with a rate of [OR] = 2.20 times higher, and those with a status anxiety score above 40 were more likely to have an organizational perception score over 80 with a rate of [OR] = 2.49 times higher (95% CI: 1.156-5.364). In addition, it was seen that the probability of having an organizational perception score above 80 was [OR] = 0.42 times higher (95%CI: 0.200-0.889) in participants who had a work accident. The intense pace of work and the pressure of fast delivery increase couriers’ state and trait concerns. Developing policies to improve the psychosocial working environment for a more decent and healthier working environment that improves the mental health and well-being of couriers is recommended. Commercial food ordering platforms must treat driver safety as important when determining delivery times.

description: Accumulation of non-essential heavy metals like chromium (Cr) is among major abiotic stresses, which adversely affect crop growth. Hexavalent chromium [Cr(VI)] is the most dangerous form negatively affecting the growth and productivity of crops. This study evaluated the role of black cumin extracts (BCE) in improving growth and productivity of maize genotypes under different concentrations of Cr(VI). Two maize genotypes (“Neelum” and “P1543”) were grown under 0, 4, 8 and 12 mg Cr(VI) kg−1 concentrations. The BCE was applied as foliar spray at three concentrations (0, 10 and 20%) at 25 and 45 days after sowing. Increasing Cr(VI) concentration significantly (p Novelty statement Black cumin has been widely used to reduce Cr toxicity in animals. However, the role of black cumin in reducing Cr toxicity in plants has never been studied. The present study was conducted to infer the role of different concentrations of black cumin extract in improving the growth of synthetic and hybrid maize genotypes under different levels of Cr stress. It is concluded that black cumin extract could be used to lower Cr toxicity in maize grown under Cr-contaminated soils.

description: Two wheel motorized vehicles used in both street transportation and recreation are a common cause of severe injury in the United States (US). To date, there has been limited data describing the spinal injury patterns among these motorcycle injury patients in the US. The goal of this study is to characterize and compare differences in specific injury patterns of patients sustaining traumatic spinal injuries after motocross (off-road) and street bike (on-road) collisions in the southwestern US at a Level I Trauma Center. Trauma registry data was queried for patients sustaining a spinal injury after motorcycle collision from 2010 to 2019 at a single Level I Trauma Center. Computed tomography (CT) scan and magnetic imaging resonance imaging (MRI) reports from initial trauma evaluation were reviewed and data was manually obtained regarding injury morphology and location. A total of 1798 injuries were identified in 549 patients who sustained a motorcycle collision, specifically 67 off-road and 482 on-road motorcycle patients. Off-road motorcycle patients were found to be significantly younger (34.75 vs. 42.66, p = 0.00015). A total of 46.2% of the off-road injuries were determined to be from compression mechanisms, compared to 32.9% in the on-road cohort (p = 0.0027). The on-road cohort was more likely to have an injury classified as insignificant, such as transverse and spinous process fractures (60.1% vs. 42.5%, p = 00.25). There was no significant difference in regards to junctional, mobile, and semirigid spine segments between the two cohorts. Different fracture patterns were seen between the off-road and on-road motorcycle cohorts. Off road motorcyclists experienced significantly more compression and translational injuries, while on road motorcyclists experienced more frequent insignificant injury patterns. Data on the different fracture patterns may help professionals develop safety equipment for motorcyclists.

Die Empfehlung zur lungenprotektiven Beatmung wird nur in einem geringen Prozentsatz angewandt. Die prospektive Analyse zeigt eine geringere Krankenhaussterblichkeit mit lungenprotektiver Beatmung. Insbesondere die Einhaltung eines niedrigen Inspirationsdruckes könnte prognostisch günstig sein, der Einfluss des körpergewichtsbezogenen Tidalvolumens scheint sekundär.

All Patients treated with mechanical ventilation in the ICU within one year, suffering from AHF and CPR were captured in our study. Lung protective ventilation if PIP <30mmHg and Vt <= 6ml/kg. Overall 129 patients. Only 17,3% received lung protective ventilation on day 1. Early establishment of LPV was associated with improved survival. Even after adjusting a significant connection between PIP and IHM could be found (coefficient of regression: 0,122, p=0,004). Our data gives in evidence about keeping low positive inspiratory pressures in cardiac intensive care patients leads to better prediction for these patients.

description: Mobile Ad-hoc Networks (MANETs) are very dynamic networks with devices continuously entering and leaving the group. The highly dynamic nature of MANETs renders the manual creation and update of policies associated with the initial incorporation of devices to the MANET (admission control) as well as with anomaly detection during communications among members (access control) a very difficult task. In this paper, we present BARTER, a mechanism that automatically creates and updates admission and access control policies for MANETs based on behavior profiles. BARTER is an adaptation for fully distributed environments of our previously introduced BB-NAC mechanism for NAC technologies. Rather than relying on a centralized NAC enforcer, MANET members initially exchange their behavior profiles and compute individual local definitions of normal network behavior. During admission or access control, each member issues an individual decision based on its definition of normalcy. Individual decisions are then aggregated via a threshold cryptographic infrastructure that requires an agreement among a fixed amount of MANET members to change the status of the network. We present experimental results using content and volumetric behavior profiles computed from the ENRON dataset. In particular, we show that the mechanism achieves true rejection rates of 95% with false rejection rates of 9%.

description: We treat quantum counterparts of testing problems whose optimal tests are given by chi-square, t and F tests. These quantum counterparts are formulated as quantum hypothesis testing problems concerning quantum Gaussian states families, and contain disturbance parameters, which have group symmetry. Quantum Hunt-Stein Theorem removes a part of these disturbance parameters, but other types of difficulty still remain. In order to remove them, combining quantum Hunt-Stein theorem and other reduction methods, we establish a general reduction theorem that reduces a complicated quantum hypothesis testing problem to a fundamental quantum hypothesis testing problem. Using these methods, we derive quantum counterparts of chi-square, t and F tests as optimal tests in the respective settings.

Intra-operative `pick-up' ultrasound for guidance and registration to pre-operative imaging

description: The integration of ultrasound into robotic laparoscopic surgery can provide a surgeon with navigational guidance that could decrease operating times and increase surgeon confidence during complicated procedures such as partial nephrectomy. CT scans are taken for diagnosis before surgery and have a wide field-of-view and high resolution but do not provide real-time information for the surgeon during surgery. Ultrasound is an inexpensive, portable, non-invasive imaging modality, which has the potential to provide the surgeon with real-time information. With accurate registration between CT and ultrasound, a surgeon can be provided with a wide field-of-view of the patients underlying anatomy, that cannot be seen through the laparoscope. Organ motion within the abdomen between the time of diagnostic scanning and intra-operative imaging can affect the accuracy of image registration. CT scans of the patients’ kidneys in both the supine (diagnostic) and flank (surgical) positions were registered to determine the extent of kidney motion. The center of mass was observed to move between 10 and 75 mm resulting in a recommendation that diagnostic CT scans be performed with the patient in the potential surgical position when image registration will be performed. This thesis presents the design of a new intra-abdominal ultrasound transducer, which can be controlled directly by the operating surgeon throughout the duration of the procedure. Initial use of the transducer is targeted for robotic laparoscopic surgery, where the operating surgeon must rely on a patient-side assistant. Multiple tracking methods have been integrated into the transducer to allow 3D ultrasound volumes to be constructed from a set of 2D slices. These methods include tracking using electromagnetic sensors, optical markers and robotic kinematics. The vessels of the kidney serve as important landmarks during the surgical procedure and can also be used as features for CT to ultrasound registration. A registration method using automatic ultrasound vessel segmentation is proposed and tested in a phantom and human model. The root mean square error in the phantom was calculated to be 3.2 mm, which is comparable to other reported registration errors, while the error in the registration using the human model was 7.5 mm.

description: In this paper we discuss the properties of the reduced density matrix of quantum many body systems with permutational symmetry and present basic quantification of the entanglement in terms of the von Neumann (VNE), Renyi and Tsallis entropies. In particular, we show, on the specific example of the spin $1/2$ Heisenberg model, how the RDM acquires a block diagonal form with respect to the quantum number $k$ fixing the polarization in the subsystem conservation of $S_{z}$ and with respect to the irreducible representations of the $\mathbf{S_{n}}$ group. Analytical expression for the RDM elements and for the RDM spectrum are derived for states of arbitrary permutational symmetry and for arbitrary polarizations. The temperature dependence and scaling of the VNE across a finite temperature phase transition is discussed and the RDM moments and the Rényi and Tsallis entropies calculated both for symmetric ground states of the Heisenberg chain and for maximally mixed states.

description: This article will help to consider the problem associated with teaching foreign languages at school. Namely, how to quickly attract the attention of schoolchildren to learning a foreign language, how to remove the distance between students and teacher. The author paid special attention to game moments, the use of which can, without straining students, unite them with each other and direct their interest in learning the language.

description: Alarms such as phone rings, smoke alarms and sirens are an important component of the acoustic world, designed to convey urgent information in an efficient and unambiguous manner. We are investigating automatic recognition of this class of sounds both because of the practical applications for the hearing impaired, and also because alarm sounds are deliberately constructed to be easily heard, making them a promising target for detection in adverse circumstances. We compare two different approaches to alarm detection, one based on techniques and representations borrowed from speech recognition, and the other more specifically designed to exploit the structure of alarm sounds and minimize the influence of background interference. In this preliminary work, both approaches achieve similarly poor error rates but with different patterns in response to alarm type and background noise.

description: A referendum took place in Greece on the 5th of July 2015 to decide whether the suggested bailout would be accepted. Since this was the first one since 1974, the period between the referendum and the subsequent national elections was characterized by increased uncertainty and had spillover effects in many aspects of everyday life. We take advantage of this quasi-experiment to investigate the short-term impact of the referendum on vehicle collisions casualties. We use data from the daily number of injuries and fatalities caused by vehicle collisions in 2015 and employ a difference-in-differences approach, comparing trends before and after the referendum. We reveal that the referendum had a short-term impact on road traffic casualties (4.14 more casualties per day), compared to what would have been expected in the absence of the referendum. The study provides evidence that negative emotions and anxiety, due to uncertainty, could promote dangerous driving behavior. Preventive and traffic control measures may need to be considered by policy makers during periods of uncertainty.

description: Proteinphosphorylierungen sind reversible posttranslationale Modifikationen, die oft als molekulare Schalter für biochemische Signalwege dienen. Sie haben wesentlichen Einfluss auf die Regulation der Photosynthese. Vergangene Studien zeigten, dass auch phosphorylierungsbedingte Langzeitanpassungen des plastidären Metabolismus, sowie der chloroplastidären und nukleären Genexpression auftreten können. Um derartige Mechanismen und Knotenpunkte der Signalwege besser zu verstehen, wurden im Rahmen dieser Dissertation Proteinphosphorylierungsstudien am Chloroplasten von Arabidopsis thaliana durchgeführt. Die Ergebnisse dieser Dissertation zeigen, dass die drei Kinasen pCKII, STN7 und STN8 Mediatoren zwischen der photosynthetischen und metabolischen Funktion, sowie der Langzeitanpassung im Chloroplasten sind.
description: Protein phosphorylations are reversible posttranslational modifications (PTMs), which serve often as molecular switches for biochemical pathways. Their influence on the regulation of photosynthesis is already well known. Former studies show a further influence on long-term acclimations of the plastid metabolism and the plastid and nuclear gene expression. In order to understand such mechanisms and network nodes of the corresponding pathways were phosphorylation studies on the chloroplasts of Arabidopsis thaliana conducted. The results of this thesis show that the three kinases pCKII, STN7 and STN8 are mediators between the photosynthetic and the metabolic function of the chloroplast and its long-term adaptation to prevailing light conditions.
