description: We propose a scheme for the calculation from the NS equations of the scaling exponents $ζ_n$ of the $n$th order correlators in fully developed hydrodynamic turbulence. The scheme is nonperturbative and constructed to respect the fundamental rescaling symmetry of the Euler equation. It constitutes an infinite hierarchy of coupled equations that are obeyed identically with respect to scaling for any set of $ζ_n$. As a consequence $ζ_n$ are determined by solvability conditions and not from power counting. It is arguedthat in order to achieve such a formulation one must recognize that the many-point space-time correlators are not scale invariant in time arguments. The assumption of full scale invariance leads unavoidably to K41 exponents. It is argued the determination of of $ζ_n$ requires equations for infinitely many renormalized objects. One ca n however proceed in controlled successive approximations by truncations of the infinite hierarchy of equations. Clues as to how to truncate without reintroducing power counting can be obtained from renormalized perturbation theory. To this aim we show that the fully resummed perturbation theory is equivalent in its contents to the exact hierarchy of equations obeyed by the $n$th order correlators and Green's function. In light of this important result we can safely use finite resummations to construct successive closures. This paper presents the conceptual and technical details of the scheme. The analysis of the high-order closure procedures which do not destroy the rescaling symmetry and the actual calculations for truncated models will be presented in a forthcoming paper in collaboration with V. Belinicher.

description: Rainfall simulation is a useful tool in the analysis of soil erosion. The use of rainfall simulators has become more widespread with the development of automated instrumentation and control systems which offer a physically based system of predicting soil erosion. A variety of simulator designs have been used. This paper describes a rainfall simulator designed for analysis of erosion on steep (2.5H: 1V) reclaimed sand slopes at two oil sand mines near Fort McMurray, Alberta. The rainfall simulator applies artificial rain on a 225 m² test site divided into two side-by-side test plots. Most rainfall simulators have used a constant intensity of rainfall throughout a given simulation event. The rainfall simulator designed for this project can vary the rainfall application rate in fifteen discrete rainfall intensity increments. Therefore, it is capable of simulating a variety of non-uniform rainfall hyetographs. The rainfall simulator consists of a system of seven nozzles on each of 27 vertical support pipes. A combination of nozzles was used to simulate a desired uniform or non-uniform rainfall hyetograph with intensities ranging from 10 mm/h to 200 mm/h. The rainfall simulator also successfully simulated extreme historic and synthetic hyetographs.

description: The dynamics of spinning test bodies, moving in rotating black hole (Kerr, Bardeen-like and Hayward-like) spacetimes, are investigated. In Kerr spacetime, all the spherical, zoom-whirl and unbound orbits are considered numerically. Along spherical orbits and for high spin, an amplitude modulation is found in the harmonic evolution of the spin precessional angular velocity, caused by the spin-curvature coupling. Along the discussed zoom-whirl and unbound orbits, the test body approaches the center so much that it passes through the ergosphere. Near and inside the ergosphere, the variation of the spin direction can be very rapid. The effects of the spin-curvature coupling is also investigated. The initial values are chosen such a way, that the body and its spin move in the equatorial plane of the coordinate space and of the comoving frame, respectively. Hence, a clear effect of the spin-curvature coupling is observed as the orbit and the spin vector leave the equatorial plane. Additional effects in the spin precessional angular velocity and in the evolution of the Boyer-Lindquist coordinate components of the spin vector is also considered. Finally, in case of different regular black holes, the spin-curvature coupling influences differently the orbit and the spin evolutions.

description: Limited research has been done on the implementation of experiential learning to align with science and engineering practices. This research project developed an instrumental case study to examine the efficacy of an experiential education framework for teaching and learning water science and engineering practices in the elementary science classroom.  This study investigates the process of a practicing scientist mentoring a 6th grade elementary science teacher and their participation in professional development activities, strategies used for preparation and practice, classroom implementation, and the consequences of student learning with two sections of science students. Data collection and analysis of teacher background surveys, unit plans provided by the teacher, classroom and field observations, and a semi-structured interview were data sources for the study. Student evidence was collected from pre/post drawing assessments, pre/posttests, reflections, and student artifacts. The findings indicated that personal, intensive long term professional development sessions had an impact on the teacher’s practice, where she was able to use the experiential framework as a guiding principle to create an outdoor and classroom-based unit on water in Earth systems. In her practice, she was able to use the framework to create analogies to make connections between natural water filtration and classroom models, and she used an integrated approach to discuss engineering and filter design. The scientist-teacher mentorship resulted in an increase in the teacher’s confidence and ability to teach elementary science topics on water science.  Students’ conceptual understanding of water cycle components and processes progressed over the course of the unit from atmospheric level to subsurface level interactions. Students achieved an understanding of physical properties of matter and hydrogeological concepts of permeability and porosity. Students were able to understand systems thinking and developed dynamic thinking.  Implications of this study indicate that the experiential learning framework is an effective pedagogical tool for teachers to introduce science and engineering practices as specified in the K-12 Framework. Using this framework, the classroom teacher was able to complete practices for planning and carrying out investigations, developing and using models, analyzing and interpreting data, and constructing and designing solutions.

Covariant hamiltonian formalism for field theory: Hamilton-Jacobi equation on the space G
Creators: name: Rovelli, Carlo
Publisher: name: arXiv
Year: 2002
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: Hamiltonian mechanics of field theory can be formulated in a generally covariant and background independent manner over a finite dimensional extended configuration space. The physical symplectic structure of the theory can then be defined over a space G of three-dimensional surfaces without boundary, in the extended configuration space. These surfaces provide a preferred over-coordinatization of phase space. I consider the covariant form of the Hamilton-Jacobi equation on G, and a canonical function S on G which is a preferred solution of the Hamilton-Jacobi equation. The application of this formalism to general relativity is equivalent to the ADM formalism, but fully covariant. In the quantum domain, it yields directly the Ashtekar-Wheeler-DeWitt equation. Finally, I apply this formalism to discuss the partial observables of a covariant field theory and the role of the spin networks --basic objects in quantum gravity-- in the classical theory.

description: In the context of a two-dimensional exactly solvable model, the dynamics of quantum black holes is obtained by analytically continuing the description of the regime where no black hole is formed. The resulting spectrum of outgoing radiation departs from the one predicted by the Hawking model in the region where the outgoing modes arise from the horizon with Planck-order frequencies. This occurs early in the evaporation process, and the resulting physical picture is unconventional. The theory predicts that black holes will only radiate out an energy of Planck mass order, stabilizing after a transitory period. The continuation from a regime without black hole formation --accessible in the 1+1 gravity theory considered-- is implicit in an S-matrix approach and suggests in this way a possible solution to the problem of information loss.

description: The complexity of modern farm management places great demands on the skill, knowledge and capability of farm managers and their families. Keeping abreast of emerging technologies and innovations that can affect each key farm enterprise, and knowing how best to marshal the resources required for profitable farm production, are key tasks of farm management. This study draws on a longitudinal data set of 240 broadacre farmers to compare and analyse their farm performance over a decade. Using structural equation modelling, we examine relationships between the farm family’s involvement in training, their human capital, their use of various innovations and ultimately the linkages of these factors to farm financial and productivity performance. Several statistically significant inter-relationships are found, and some factors are shown to have significant positive links to farm performance. We find that training undertaken by the farm family, the farm family’s human capital and their use of innovations, particularly key cropping innovations, have significant beneficial impacts on farm performance. The farmer’s skills in time and organisational management, their engagement in business planning and the unique environmental characteristics of the farm also significantly and positively influence farm performance.

description: We describe a new method to derive clean, iodine-free spectra directly from observations acquired using high-resolution echelle spectrographs equipped with iodine cells. The main motivation to obtain iodine-free spectra is to use portions of the spectrum that are superimposed with the dense forest of iodine absorption lines, in order to retrieve lines that can be used to monitor the magnetic activity of the star, helping to validate candidate planets. In short, we provide a straight-forward methodology to clean the spectra by using the forward model used to derive radial velocities, the Line Spread Function information plus the stellar spectrum without iodine to reconstruct and subtract the iodine spectrum from the observations. We show our results using observations of the star $τ$ Ceti acquired with the PFS, HIRES and UCLES spectrographs, reaching an iodine-free spectrum correction at the $\sim$1% RMS level. We additionally discuss the limitations and further applications of the method.

description: To mitigate environmental impacts associated with improvements to an electrical facility, B.C. Hydro partnered with the Ministry of Environment Land and Parks (MoELP) and the City of Surrey to restore fish habitat in McLellan Creek. The creek, a tributary of the Nicomekl River, was modified in the 1960's, resulting in removal of upstream access and the deposition of fine silt over much of the remaining habitat. The challenge met by the restoration design was to provide upstream access and quality habitat for salmonids at low flows, while maintaining the flood control function of the channel at high flows. This was achieved through removal of four concrete weirs and enhancing the stream with a variety of structures, substrates and native vegetation. The restored channel contains over 300 meters of spawning habitat for coho salmon (Oncorynchus kisutch) and chum salmon (O. keta) and 300 meters of salmonid rearing habitat. The project provided a unique opportunity to involve the local community. The area surrounding McLellan Creek contains a protected nature lagoon and regional park and is used extensively for walking, cycling and observing nature. Including suggestions from neighborhood residents, special interest groups and municipal committees into the restoration plan was a positive experience that ultimately added value to the project. Initial results include documented spawning by chum and coho salmon and the successful passage of a 1 in 50 year flood event. Plans for next year include continued monitoring of fish activity and an engineering assessment of the channel.

We combine Sapozhenko's graph container methods with the cluster expansion and abstract polymer models, two tools from statistical physics, to obtain considerably sharper asymptotics and detailed probabilistic information about the typical structure of (weighted) independent sets in the hypercube. These results refine those of Korshunov and Sapozhenko and Galvin, and answer several questions of Galvin.

description: Equilibrium Displacement Models (EDMs) are useful for estimating the net benefits of investments in agricultural research, development and extension (RD&E) and the distribution of these benefits between producers and other participants in the value chain. Information from these models can inform investment decisions by funders of RD&E. In this paper the design and construction of an EDM for the Western Australian grains industry, a major component of the national grains industry, is reported. Using the EDM, two RD&E investment scenarios are examined. The first scenario is for a 1 per cent reduction in the cost of farm production inputs as a result of an investment in RD&E, while the second scenario involved a 1 per cent increase in the willingness of overseas consumers to pay for wheat as a result of an investment in RD&E. The results show that the farm sector and overseas consumers are the major beneficiaries under each scenario. The WA grains industry is characterised by a short supply chain, where most grain production is exported. The large volume of grain exported means that, if there is an increase in demand or supply, some of the total benefits go to consumers overseas. Still, a high price elasticity of demand for export grains ensures that the farm production sector receives the majority of total benefits, and that these benefits outweigh the share of benefits received by overseas consumers.

description: The rate of quantum ergodicity is studied for three strongly chaotic (Anosov) systems. The quantal eigenfunctions on a compact Riemannian surface of genus g=2 and of two triangular billiards on a surface of constant negative curvature are investigated. One of the triangular billiards belongs to the class of arithmetic systems. There are no peculiarities observed in the arithmetic system concerning the rate of quantum ergodicity. This contrasts to the peculiar behaviour with respect to the statistical properties of the quantal levels. It is demonstrated that the rate of quantum ergodicity in the three considered systems fits well with the known upper and lower bounds. Furthermore, Sarnak's conjecture about quantum unique ergodicity for hyperbolic surfaces is confirmed numerically in these three systems.

description: In this paper we study the production of pairs of neutral and charged black holes by domain walls, finding classical solutions and calculating their classical actions. We find that neutral black holes whose creation is mediated by Euclidean instantons must be produced mutually at rest with respect to one another, but for charged black holes a new type of instanton is possible in which after formation the two black holes accelerate away from one another. These new types of instantons are not possible in Einstein-Maxwell theory with a cosmological constant. We also find that the creation of non-orientable black hole solutions can be mediated by Euclidean instantons and that in addition if one is prepared to consider entirely Lorentzian no-boundary type contributions to the path integral then mutually accelerating pairs may be created even in the neutral case. Finally we consider the production of Kaluza-Klein monopoles both by a standard cosmological term and in the presence of a domain wall. We find that compactification is accompanied by the production of pairs of Kaluza-Klein monopoles.

description: As virtually all aspects of our lives are increasingly impacted by algorithmic decision making systems, it is incumbent upon us as a society to ensure such systems do not become instruments of unfair discrimination on the basis of gender, race, ethnicity, religion, etc. We consider the problem of determining whether the decisions made by such systems are discriminatory, through the lens of causal models. We introduce two definitions of group fairness grounded in causality: fair on average causal effect (FACE), and fair on average causal effect on the treated (FACT). We use the Rubin-Neyman potential outcomes framework for the analysis of cause-effect relationships to robustly estimate FACE and FACT. We demonstrate the effectiveness of our proposed approach on synthetic data. Our analyses of two real-world data sets, the Adult income data set from the UCI repository (with gender as the protected attribute), and the NYC Stop and Frisk data set (with race as the protected attribute), show that the evidence of discrimination obtained by FACE and FACT, or lack thereof, is often in agreement with the findings from other studies. We further show that FACT, being somewhat more nuanced compared to FACE, can yield findings of discrimination that differ from those obtained using FACE.

description: در حال حاضر، طیف گسترده‌ای از موارد پزشکی باعث معافیت دائم و یا خدمات رزمی برای مشمولان می‌شود. این در حالی است که برخی جنبه‌های پزشکی فرد مشمول حتی حین خدمت نیز نیاز به رسیدگی دارند و لازم است تا رده خدمتی به‌منظور حفظ کیفیت دوران سربازی و انگیزه بخشی و عدم بروز مشکلات جسمی و رانی بیش‌تر نهایت تعامل را با آنان داشته باشد؛ چیزی که در عمل به دلیل تبعیت برخی سازمان‌ها صرفاً از آیین‌نامه‌های از پیش تعیین‌شده با چالش‌های فراوانی روبه‌رو است.
Modernisiertes Patriarchat? Von der heterosexuellen Liebe zwischen ‚Schlampen‘, ‚Prinzessinnen‘ und ‚(Nicht-)Rittern‘, wie sie Jugendliche erzählen

description: Der Begriff des Patriarchats ist aus der Geschlechterforschung fast verschwunden, was jedoch mit dem Blick auf Erzählungen Jugendlicher über die Liebe fragwürdig erscheint. In Gruppendiskussionen und Einzelinterviews wird die Liebe von jugendlichen Real- und Berufsschüler_innen nicht nur als heteronormatives Projekt, sondern auch als patriarchales Projekt erzählt. Heterosexuelle Liebe braucht demnach die Hierarchie zwischen aktiven, dominanten Jungen (‚Rittern‘ und ‚Nicht-Rittern‘) und passiven Mädchen (‚Prinzessinnen‘ und ‚Nicht-Schlampen‘) ebenso wie scheinbar gleichberechtigte Aushandlungsprozesse. Verwiesen wird damit auf ein modernisiertes Patriarchat, das als gesellschaftliches Herrschaftsverhältnis zwar widersprüchlich, aber dennoch weiterhin wirkmächtig ist.
description: Modernized patriarchy? How adolescents narrate heterosexual love between “sluts”, “princesses” and “(non-)cavaliers” The concept of patriarchy has almost disappeared from gender studies. However, given how adolescents actually narrate love, this appears questionable. In group discussions and interviews adolescents talk about love not only as a heteronormative project but also as a patriarchal project. According to these narratives, heterosexual love needs a hierarchy between active, dominant boys (“cavaliers” and “non-cavaliers”) and passive girls (“prin- cesses” and “non-sluts”), as well as apparent- ly equal negotiation processes. These ideas can be interpreted as a reference to a modernized patriarchy which is inconsistent but in fact still remains effective as a form of social dominance.
The prehistoric land-use and human ecology of the Malling-Caburn Downs: Two Late Neolithic / Earlty Bronze Age sites beneath colluvial sequences
Creators: name: Allen, Michael J
Publisher: name: Archaeology Data Service
Year: 2021

description: Sussex Archaeological Collections, 133, 19-43
description: The analysis of two significant colluvial deposits (at Southerham Grey Pit and Malling Hill) on the Malling-Caburn block of downland to the east of Lewes has enabled a detailed landscape history to be constructed for this area. This paper attempts to provide a summary of the human role in the development of the chalk/and block of Malling, Cliff and Ca bum. It includes evidence primarily from these two colluvial sequences, but comprises a review of other environmental archaeological data including some recent analysis of archived soil samples from Burstow and Holleyman's (1964) excavations at Ranscombe Camp. The important land mollusc evidence from Round-the-Down (Allen, in Butler this volume) is also reviewed. To conclude, an attempt is made to show how the detailed landscape history from these sites equates with the broader picture from downland in the region of Lewes.

description: We revisit occurrence typing, a technique to refine the type of variables occurring in type-cases and, thus, capturesome programming patterns used in untyped languages. Although occurrence typing was tied from its inceptionto set-theoretic types-union types, in particular-it never fully exploited the capabilities of these types. Here weshow how, by using set-theoretic types, it is possible to develop a general typing framework that encompasses andgeneralizes several aspects of current occurrence typing proposals and that can be applied to tackle other problemssuch as the reconstruction of intersection types for unannotated or partially annotated functions and the optimizationof the compilation of gradually typed languages.
Reconstruction of inhomogeneous metric perturbations and electromagnetic four-potential in Kerr spacetime
Creators: name: Ori, Amos
Publisher: name: arXiv
Year: 2002
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: We present a procedure that allows the construction of the metric perturbations and electromagnetic four-potential, for gravitational and electromagnetic perturbations produced by sources in Kerr spacetime. This may include, for example, the perturbations produced by a point particle or an extended object moving in orbit around a Kerr black hole. The construction is carried out in the frequency domain. Previously, Chrzanowski derived the vacuum metric perturbations and electromagnetic four-potential by applying a differential operator to a certain potential $Ψ$. Here we construct $Ψ$ for inhomogeneous perturbations, thereby allowing the application of Chrzanowski's method. We address this problem in two stages: First, for vacuum perturbations (i.e. pure gravitational or electromagnetic waves), we construct the potential from the modes of the Weyl scalars $ψ_{0}$ or $ϕ_{0}$. Second, for perturbations produced by sources, we express $Ψ$ in terms of the mode functions of the source, i.e. the energy-momentum tensor $T_{αβ}$ or the electromagnetic current vector $J_α$.

description: همان‌گونه که میدانیم برون‌سپاری و یا جمع سپاری در حال حاضر یکی از راه‌های کاهش هزینه‌ها و مدیریت بهینه منابع انسانی سازمانی است. در برون‌سپاری عملاً هسته‌های مرکزی سازمان به تفکر می‌پردازند و فرآیندهای اجرایی و زمان‌بر را با دستورالعملی مشخص به سایرین می‌سپاریم و به این‌گونه بدون گسترش ساختار سازمانی که به‌تبع آن دچار مشکلات فراوان مدی‌تری می‌شویم، به‌راحتی و برای هر پروژه می‌توانیم در کم‌ترین زمان و بهینه‌ترین حالت به مقصود برسیم. با توجه به این‌که فرآیند سربازی مستلزم ورود سازمان‌های متعدد و قانون‌گذاری‌های پیچیده است و کوچک‌ترین تغییری در هر قانون و بند و تبصره مستلزم بررسی تعارضات قانونی و راهکارهای عملیاتی آن است، به نظر می‌رسد تدوین سازوکاری جهت به‌روزرسانی و بررسی دوره‌ای قوانین سربازی می‌تواند به نیروهای مسلح در بهینه‌سازی هر چه بهتر امور و ساماندهی فرآیندهای سربازی کمک شایانی نماید.

description: The Galactic center supermassive black hole (SMBH) Sagittarius A* (Sgr A*) is the closest such object and thus is an ideal target for investigation of galactic nuclei and their activity cycles. Its remarkable underluminous X-ray state is punctuated by outbursts on different time and energy scales. This thesis presents a study of past, current and possible future X-ray outburst activities from Sgr A*, using the hard X-ray telescope NuSTAR. Indication of substantial past Sgr A* activity, similar to that observed in low-luminosity active Galactic nuclei, has come from the Galactic center molecular clouds (GCMCs). Using these X-ray reflecting GCMCs, I have studied the characters of past Sgr A* X-ray outbursts. The current X-ray quiescence of Sgr A* is punctuated by directly detectable flares. The radiation mechanism and physical process of these X-ray flares are poorly understood. From about 1 Ms NuSTAR observations of Sgr A*, I collected nine bright X-ray flares. I studied their timing behavior and the correlation between flares' strengths and their spectra. Future Sgr A* X-ray activity could increase due to the infall of a gas cloud G2 into this SMBH. Finally, I present the Galactic center cosmic-ray population revealed by non-thermal X-ray filaments and its connection to Sgr A* outbursts.

description: In-Band Full-Duplex (IBFD) is a technique that enables a wireless node to simultaneously transmit a signal and receive another on the same assigned frequency. Thus, IBFD wireless systems can provide up to twice the channel capacity compared to conventional Half-Duplex (HD) systems. In order to study the feasibility of IBFD networks, reliable models are needed to capture anticipated benefits of IBFD above the physical layer (PHY). In this paper, an accurate analytical model based on Discrete-Time Markov Chain (DTMC) analysis for IEEE 802.11 Distributed Coordination Function (DCF) with IBFD capabilities is proposed. The model captures all parameters necessary to calculate important performance metrics which quantify enhancements introduced as a result of IBFD solutions. Additionally, two frame aggregation schemes for Wireless Local Area Networks (WLANs) with IBFD features are proposed to increase the efficiency of data transmission. Matching analytical and simulation results with less than 1% average errors confirm that the proposed frame aggregation schemes further improve the overall throughput by up to 24% and reduce latency by up to 47% in practical IBFD-WLANs. More importantly, the results assert that IBFD transmission can only reduce latency to a suboptimal point in WLANs, but frame aggregation is necessary to minimize it.

description: از برنامه‌های مطلوب و متعالی ستاد کل نیروهای مسلح اعطای پروژه‌های کسری خدمت به متقاضیان است. این فرآیند به‌طورکلی در سازمان‌ها به این نحو است که متقاضی به‌صورت حضوری و یا غیرحضوری مراجعه نموده و مستندات و رزومه و توانمندی‌های خود را تحویل داده و منتظر می‌شود تا این‌که سازمان برای وی پروژه‌ای اختصاص دهد و یا به او اعلام عدم نیاز کند. در حالت اول که پروژه به فرد اختصاصاً می‌باید حتی با وجود گذشت زمان زیاد اما متقاضی به هدف رسیده و مشکل خیلی حاد نیست اما در حالتی که به فرد عدم نیاز پس از مدت‌زمان زیادی اعلام شود، وی به دلایل گوناگون از جمله کمبود زمان یافتن پروژه‌های دیگر شاید بعضاً از این امکان محروم شود. به نظر می‌رسد می‌توان با تغییرات اندکی در روش فعلی اعطای پروژه‌های کسر/جایگزین خدمت این فرآیند را تا حد زیادی بهبود بخشید.
In-pit disposal program for acid generating waste rock

description: For many years open pits have been used for the disposal of waste rock. Mine waste disposal has become an environmental issue that is watched closely by government agencies and the public due to the legacies of past mine waste disposal methods. An in-pit disposal program for acid generating waste rock was: conducted by Lakefield Research Limited at an abandoned mine site which operated as an open pit and underground mine. The mine was closed in 1975 and the mine property was included in a provincial park. Prior to commencing the in-pit disposal program, an Environmental Site Assessment (ESA) of the mine property was conducted. The data collected during the ESA was used to develop a reclamation program that would address the site specific conditions that would maximize the on site resources to minimize the costs of the reclamation program. A testing program was conducted as part of the ESA. The data from the testing program was used to determine the acid generating potential of the waste rock and the surface water quality. Two locations containing waste rock were generating acid during the ESA which had not generated acid at the time of closure, in 1975. One location was an acid generating waste rock dump at a ramp location, hi[in] addition, the access road to the ramp area was constructed of acid generating waste rock. The second location was along the shore of a river, where acid generating waste rock had been used for construction of an access road for a pump house. The water quality of the pit water was within the Class 1 and Class 2 Manitoba Surface Water Quality Objectives and there was no evidence of the pit wall rock degrading the water quality. The quality of the pit water determined that a volume of the pit water could be discharged to the environment prior to placement of the waste rock in the pit. Prior to the field program, the effect of placing the waste rock into the flooded open pit was determined by completing a laboratory column test with the waste rock and the open pit water. The results of the program were used to help predict any changes in water quality that would occur during dewatering of the open pit and waste rock placement. The acid generating waste rock was effectively disposed of in the flooded open pit using a simple underwater disposal method.
