Dam-break computations by a finite volume on dry regions

This paper presents numerical solvers, based on the finite volume method. This scheme solves dam break problems on the dry bottom in 2D configuration. The difficulty of the simulation of this type of problem lies in the propagation of shocks on the dry bottom. The equation model used is the shallow water equations written in conservative form. The scheme used is second order in space and time. The method is modified to treat dry bottoms. The validity of the method is demonstrated over the dam break example. A comparison with finite elements shows the weakness and robustness of each method.

Modern Orthosis Therapy for Scoliosis, Kyphosis and other postural defects. Report by Dr. David Rosenberg, M.D. of Georgia and colleagues.

As a conservative form of treatment for scoliosis and kyphosis (postural deficits), orthotic therapy still represents the gold standard of non-surgical orthopedics. In light of increasingly frequent complications due to dangerous wound infections caused by multi-resistant germs, it is to be expected that the treatment of clinically relevant postural deformities will again be increasingly conservative in the future. Apart from “saving” the patient from wearing an orthosis, surgical (invasive) treatment has not been proven to be superior.

Fluid Dynamics in Curvilinear Coordinates without Fictitious Forces

The use of curvilinear coordinates is sometimes indicated by the inherent geometry of a fluid dynamics problem, but this introduces fictitious forces into the momentum equations that spoil the strict conservative form. If one is willing to work in three dimensions, these fictitious forces can be eliminated by solving for rectangular (Cartesian) momentum components on a curvilinear mesh. A thoroughly geometric approach to fluid dynamics on spacetime demonstrates this transparently, while also giving insight into a greater unity of the relativistic and nonrelativistic cases than is usually appreciated.

Queer Narrative Theory and the Relationality of Form

This essay contests the antinarrative foundations of queer literary studies. Antinarrativity understands narrative as a conservative form that abets heteronormativity by imposing a coherence and linearity on subjectivity and meaning. By contrast, this essay reframes narrative as a relational form rife with affordances for figuring and sustaining queer bonds. I trace these affordances through contemporary queer kinship narratives, including Paul B. Preciado's Testo Junkie, Maggie Nelson's The Argonauts, and Renee Gladman's Calamities. These texts reveal unexpectedly queer potentials within address, contiguity, closure, and even linearity, which queer theory misses when it defines narrative as inherently teleological and when it locates queerness primarily in transgressive ruptures. This essay discovers queerness instead within mundane and messy attachments that endure across time and space. Queer narrative theory thus emerges in this essay as a relational formalism well-suited to debates about the shapes queerness takes now.

TRENDS IN PRESS COVERAGE OF FEMINIST ACTIVITY IN THE UAE MEDIA: AN ANALYTICAL STUDY

This study seeks to shed light on Arab societies in general and the Emirati society in particular, as we find that customs and traditions have given the conservative form of women, Which, in turn, is reflected in the entirety of its relations, and its social and cultural processes in particular are closely related to the media institution that reproduced this model by adopting conservative contents, except in very few cases, which is often associated with some feminist institutions. In this study, the researchers focused on identifying the most important shapes, templates, trends, and areas occupied by all of these coverage. And then determine its contents and meanings. that is through analyzing the coverage and its types and all the arts of journalistic editing, News coverage is made up of the type of news and report, while the explanatory coverage is by the type of press article Investigation and press dialogue, as for the documentary coverage, it is related to the means of highlighting, whether they are news or non-news photos, figures and drawings.

Conservative Finite Volume Schemes for Multidimensional Fragmentation Problems

In this article, a new numerical scheme for the solution of the multidimensional fragmentation problem is presented. It is the first that uses the conservative form of the multidimensional problem. The idea to apply the finite volume scheme for solving one-dimensional linear fragmentation problems is extended over a generalized multidimensional setup. The derivation is given in detail for two-dimensional and three-dimensional problems; an outline for the extension to higher dimensions is also presented. Additionally, the existing one-dimensional finite volume scheme for solving conservative one-dimensional multi-fragmentation equation is extended to solve multidimensional problems. The accuracy and efficiency of both proposed schemes is analyzed for several test problems.

Optimized lepton universality tests in $$B\rightarrow V \ell {\bar{\nu }}$$ decays

We propose improved lepton flavor universality (LFU) ratios in semileptonic $$P\rightarrow V \ell {\bar{\nu }}$$ P → V ℓ ν ¯ decays, when comparing $$\mu $$ μ and $$\tau $$ τ modes, that minimize the theoretical form-factor uncertainties. These optimized ratios are obtained with simple cuts or reweighting of the dilepton mass distributions, which imply a minimum loss of signal on the rare tauonic modes while maximizing the cancellation of theoretical uncertainties among the two modes. We illustrate the usefulness of these observables in $$B_c\rightarrow J/\psi $$ B c → J / ψ , $$B_c\rightarrow \psi (2S)$$ B c → ψ ( 2 S ) , $$B\rightarrow D^*$$ B → D ∗ and $$B_s\rightarrow D_s^*$$ B s → D s ∗ transitions, showing that in all cases we can reach $${\mathcal {O}}(1\%)$$ O ( 1 % ) uncertainties on the SM predictions of the improved LFU ratios employing conservative form-factor uncertainties.
