La politica della legalità : il ruolo del giurista nell'età contemporanea
No full textAs the author of this book shows as he tests his theses, impartiality and justice require specific and scrupulous forms of civil engagement which render obsolete the traditional call for neutrality. At the same time, citizens must be made to understand how formal features of law that usually evoke their hostility actually guarantee their rights. The legal professional must learn to be a "relativist", obliged - through his choices - to establish priorities among distinct and often irreconcilable value domains
Effector function of leucocytes from susceptible and resistant mice against distinct isolates of Candida albicans
No full textNeutrophils and macrophages were generated in vitro from mice that display either high or low tissue susceptibilities to Candida albicans infection and their ability to phagocytose and kill three isolates of the yeast with different virulence characteristics was evaluated. In the absence of opsonization, phagocytosis by BALB/c and CBA/CaH neutrophils was comparable, but the killing was very poor. Opsonization with normal serum slightly decreased phagocytosis, but it had markedly different effects on killing, either enhancing or inhibiting candidacidal activity, depending on the combination of yeast isolate and mouse strain. In contrast, BALB/c macrophages showed high levels of phagocytosis and killing of both unopsonized yeasts and opsonized yeasts; whereas killing of unopsonized yeasts by CBA/CaH macrophages was poor, it was markedly enhanced by opsonization
Cercando di dimenticare Savigny
No full textIl presente scritto è un contributo alla discussione del libro di Aurelio Gentili, Il
diritto come discorso del 2013. Del predetto volume si approvano senza riserve
a) la critica alla concezione del vecchio positivismo, secondo il quale il giurista
non farebbe altro che esplorare un misterioso oggetto denominato “realtà
giuridica”, e b) l’interesse per le tecniche argomentative quali strumenti di
controllo interno dei discorsi. Sul piano propositivo, l’autore della recensione
ammette che la conoscenza dei significati normativi letterali, quando la si
ritiene rilevante, comporta a livello collettivo (ma assai meno al livello dei
singoli) un giudizio partecipante. Tali significati, del resto, lungi dall’essere
entità fisse, sono sempre in movimento. Ciò stabilito e con questi limiti,
occorre ammettere che non c’è solo un ordo ordinans imposto dai giuristi sui
confusi materiali estratti dalle fonti, ma si può scorgere, e si deve ritrovare,
anche un ordo ordinatus, frutto tanto dell’attività legislativa quanto delle precedenti interpretazioni, che il singolo interprete non può far a meno di
riconoscere. Insomma: tra i due ordini, fra le attività dei giuristi e i prodotti di
tali attività, si stabilisce un rapporto dialettico.This article is a contribution to the discussion regarding Aurelio Gentili’s 2013
book Il diritto come discorso. From the said volume, the author fully approves:
a) the criticism of the old positivism’s conception that a lawyer does nothing
but explore the misterious object that is “legal reality”, and b) the interest in
argumentative techniques as instruments for internal control of discourses. The
author of this article proposes admitting that the knowledge of literal normative
meanings, when believed to be relevant, requires at the level of the collective
(much less so at the individual level) a judgment, which demonstrates
participation. These meanings are, moreover, far from being fixed entities,
always changing. Within these limits, it should be admitted that there is not
only an ordo ordinans, made by the jurists, using the confused materials
extracted from the sources, but that we may also observe, and must rediscover,
an ordo ordinatus, which results from both legislative activity and previous
interpretations – that an individual interpreter cannot but recognize. In short, a
dialectic relationship between the two orders, between the activity of lawyers
and the products of these activities, is thus established
Exact two-dimensionalization of low-magnetic-Reynolds-number flows subject to a strong magnetic field
No full textWe investigate the behavior of flows, including turbulent flows, driven by a horizontal body-force and subject to a vertical magnetic field, with the following question in mind: for very strong applied magnetic field, is the flow mostly two-dimensional, with remaining weak three-dimensional fluctuations, or does it become exactly 2D, with no dependence along the vertical? We restrict attention to low-magnetic-Reynolds number (Rm) flow. Because liquid metals have low magnetic Prandtl number, such low- flows can have a kinetic Reynolds number as large as one million and therefore be strongly turbulent. We first focus on the quasi-static approximation, i.e. the asymptotic limit of vanishing magnetic Reynolds number Rm << 1: we prove that the flow becomes exactly 2D asymptotically in time, regardless of the initial condition and provided the interaction parameter N is larger than a threshold value. We call this property absolute two-dimensionalization: the attractor of the system is necessarily a (possibly turbulent) 2D flow. We then consider the full-magnetohydrodynamic equations and we prove that, for low enough Rm and large enough N, the flow becomes exactly two-dimensional in the long-time limit provided the initial vertically-dependent perturbations are infinitesimal. We call this phenomenon linear two-dimensionalization: the (possibly turbulent) 2D flow is an attractor of the dynamics, but it is not necessarily the only attractor of the system. Some 3D attractors may also exist and be attained for strong enough initial 3D perturbations. These results shed some light on the existence of a dissipative anomaly for magnetohydrodynamic flows subject to a strong external magnetic field
The use of CFSE-like dyes for measuring lymphocyte proliferation: experimental considerations and biological variables
No full textThe measurement of CFSE dilution by flow cytometry is a powerful experimental tool to measure lymphocyte proliferation. CFSE fluorescence precisely halves after each cell division in a highly predictable manner and is thus highly amenable to mathematical modelling. However, there are several biological and experimental conditions that can affect the quality of the proliferation data generated, which may be important to consider when modelling dye dilution data sets. Here we overview several of these variables including the type of fluorescent dye used to monitor cell division, dye labelling methodology, lymphocyte subset differences, in vitro versus in vivo experimental assays, cell autofluorescence, and dye transfer between cells.B.J.C.

Flow instabilities and reversals in non-uniformly thermocapillary driven melt pool
No full textWith transient LES and DNS simulations, we investigate flow in melt pools driven by thermocapillary forces. The developing pool is at first axisymmetric as are the boundary conditions, but flow instabilities arise that lead to 3D oscillatory flow patterns. At higher laser powers a sign-change in the surface tension temperature coefficient occurs, resulting in a flow reversal in the pool and thus two counter-rotating vortices, which exhibit similar though more complex flow instabilities
Cosmopolitan Christianity: The Case of Bishop C.R. Duppuy, 1881-1944
No full textExisting research in Global History and the history of World Christianity has compellingly demonstrated transnational connections through the study of cultural encounter and intellectual exchange. Transnational relationships between historical actors and events are most easily detected through visible and measurable indicators. For cross-cultural Christianity, this includes rituals, printed material, and architecture. My communication seeks to use the alternative approach of biography as a means of exploring World Christianity and global connections. The life of C.R. Duppuy, Bishop of Victoria (Hong Kong) and later Assistant Bishop of Worcester, not only affirms the worldwide interconnectedness of canon law, theology, and social practice, but also exposes relatively under-studied links such as family, friendship networks, and administrative methods across the international Anglican Communion. For example, whilst most historians would rightly connect Bishop Duppuy’s plans to reform the Diocese of Victoria in 1920 with the recent Lambeth Conference he attended and national Christian conferences in China, few would realize that the practical measures he used to implement the reform were gleaned from his former colleagues at the Church Missionary Society, fellow bishops who were his friends, and his former superior at Aston Parish Church where he began his career as a curate. The case of Bishop C.R. Duppuy serves as a reminder to Global History and studies in World Christianity to look beyond the external signs of cultural encounter and instead towards subtler and more personal elements of cosmopolitanism
Wall to wall optimal transport
No full textThe calculus of variations is employed to find steady divergence-free velocity fields that maximize transport of a tracer between two parallel walls held at fixed concentration for one of two constraints on flow strength: a fixed value of the kinetic energy or a fixed value of the enstrophy (the mean square rate of strain in this situation). The optimizing flows realize upper limits on convective transport in this scenario. We interpret the results in the context of buoyancy-driven Rayleigh–Bénard convection problems that satisfy the flow intensity constraints, enabling us to investigate how optimal transport scalings compare with upper bounds on Nu expressed as a function of the Rayleigh number Ra
Holding on to What is Most Precious: Ohio Juvenile Law after In re C.R.
No full textThis article will endeavor to show that the Ohio Supreme Court’s ruling in In re C.R. makes it too difficult for parents to retain custody of their own children. By exploring United States Supreme Court precedent, it will be shown that the rule emerging from In re C.R. does not pass procedural due process muster. It will also be shown that the Ohio Supreme Court disregarded its own precedent and in doing so, created a rule that undermines the policies of its own juvenile law system. By providing the rudiments of juvenile jurisprudence, the facts and decision of In re C.R., and an analysis that shows the Ohio Supreme Courts’ oversights and errors in its decision, the author hopes to persuade Ohio lawmakers to reevaluate the way that juvenile court custody cases should be conducted in the future
