LA TECNICA Y LA CRISIS FILOSOFICA DEL HUMANISMO

2008

Los acontecimientos civilizatorios que emblemáticamente representamos con nombres como Auschwitz o Hiroshima han hecho visible que la comprensión de la realidad como técnicamente abordable obliga a replantear problemas centrales para la filosofía: la omnipresencia de la técnica transforma el modo de vida de los individuos y las sociedades contemporáneas, el vínculo del hombre con la naturaleza y el vinculo social, no menos que los modos de construcción de la subjetividad humana. El presente escrito intenta oponer a la destrucción heideggeriana del sujeto la idea de que, en la presente crisis abierta por las posibilidades inéditas de las tecnologías, es imprescindible una reconstrucción del …

'A Shared Reality between a Journalist and the Audience': How Live Journalism Reimagines News Stories

2021

Live journalism is a new journalistic genre in which journalists present news stories to a live audience. This article investigates the journalistic manuscripts of live journalism performances. With the focus on texts, the article reaches beyond the live performance to explore the wider implications and potentials pioneered by live journalists. The data were gathered from <em>Musta laatikko</em> (‘Black Box’) manuscripts, a live journalism production by the Finnish newspaper <em>Helsingin Sanomat</em>. The manuscripts were analysed as <em>eudaimonic journalism</em> through four conceptual dimensions: self-transcendence, autonomy, competence, and relatedne…

Wound drainages in total hip arthroplasty: to use or not to use? Review of the literature on current practice.

2013

Aim of this study is to analyze data reported in literature concerning the efficacy of using wound low-vacuum suction drainages in orthopedic surgery after total hip arthroplasty. We analyzed studies concerning the use of drainages in prosthetic hip replacement surgery, performing our research through Pubmed, Cochrane database and Google Scholar, and selecting the ones evaluating the following parameters: bleeding, the need for blood transfusions, number or reinforcement of post-operative medications, length of hospitalization, functional results, periprosthetic and surgical wound infection, post-operative hematoma. Our review did not show any demonstrated advantage from the use of wound dr…

Molecular Search of New Active Drugs AgainstToxoplasma Gondii

1999

Molecular connectivity has been applied to the search of new compounds with activity against the protozoan Toxoplasma gondii, using a stepwise linear discriminant analysis (SLDA) which is able to classify a compound according its activity either as active or as inactive. Among the selected compounds, andrographolide and dibenzotiophene sulfone stand out, both with IC50 values lower than 1 microgram/ml, which are comparable to these of drugs such as sulfamethoxazole, pyrimethamine and trimethoprim, with IC50 values equal to 1.1, 0.04 and 2.31 micrograms/ml, respectively. These results confirm the usefulness of our topological approach for the selection and design of new-lead drugs active aga…

Highly sensitive superconducting circuits at ∼700 kHz with tunable quality factors for image-current detection of single trapped antiprotons

2016

We developed highly-sensitive image-current detection systems based on superconducting toroidal coils and ultra-low noise amplifiers for non-destructive measurements of the axial frequencies (550$\sim$800$\,$kHz) of single antiprotons stored in a cryogenic multi-Penning-trap system. The unloaded superconducting tuned circuits show quality factors of up to 500$\,$000, which corresponds to a factor of 10 improvement compared to our previously used solenoidal designs. Connected to ultra-low noise amplifiers and the trap system, signal-to-noise-ratios of 30$\,$dB at quality factors of > 20$\,$000 are achieved. In addition, we have developed a superconducting switch which allows continuous tu…

Non-Equilibrium Thermodinamic analysis of rotating counterflow superfluid turbulence

2008

Two alternative evolution equations for the vortex line density L in counterflow superfluid turbulence in 4He were proposed by Vinen in 1958. These equations was recently generalized to counterflow superfluid turbulence in rotating containers. Here, according with the formalism of Non-Equilibrium Thermodynamics, the compatibility between the alternative Vinen equation as evolution equation for the vortex line density in rotating counterflow turbulence and the velocity of the superfluid component is studied. From the compatibility request a new term dependent on the anisotropy of the tangle arises.

Ciprofloxacin carrier systems based on hectorite/halloysite hybrid hydrogels for potential wound healing applications

2021

The design of multifunctional nanomaterials which can help the healing processes of skin, preventing the bacterial infections, is crucial for the development of suitable therapy for the treatment of chronic lesions. The use of clay minerals in wound healing applications is well documented since the prehistoric period and offers several advantages due to their intrinsic properties. Herein, we report the development of ciprofloxacin carrier systems based on hectorite/halloysite (Ht/Hal) hybrid hydrogels for potential wound healing applications. To achieve this objective firstly the ciprofloxacin molecules were loaded onto Hal by a supramolecular and covalent approach. The so obtained fillers …

Tra Sicilia e America: gli “scappati” di Cosa Nostra,

2009

Territorial control is one of the most important elements for the survival of the mafia. It is an obligated path to be able to obtain and control economic activities and to penetrate into all profitable sectors. Without territorial control it is impossible to control voters and without it all relationships with politics wither and die. It is within the territory where the imposition of "pizzo" (protection money) and extortion are planned against businesses and firms. This impending presence is also the cause in which citizens and families find themselves submitted to violence, the abuse of power and, if not only, to a limitation to their sphere of action. Telling the story about the scappat…

Sympathetic cooling of a trapped proton mediated by an LC circuit

2021

Efficient cooling of trapped charged particles is essential to many fundamental physics experiments1,2, to high-precision metrology3,4 and to quantum technology5,6. Until now, sympathetic cooling has required close-range Coulomb interactions7,8, but there has been a sustained desire to bring laser-cooling techniques to particles in macroscopically separated traps5,9,10, extending quantum control techniques to previously inaccessible particles such as highly charged ions, molecular ions and antimatter. Here we demonstrate sympathetic cooling of a single proton using laser-cooled Be+ ions in spatially separated Penning traps. The traps are connected by a superconducting LC circuit that enable…
