Cambio de paradigma en la difusión y divulgación libre del conocimiento: el acceso de la literatura en abierto en la Universidad
Charla académica
Francisco José García Peñalvo, Tránsito Ferreras Fernández, José Antonio Merlo Vega e Iván Pérez Miranda
En la actual sociedad del conocimiento, las universidades deben cumplir una función crítica y social contribuyendo al desarrollo a través de acciones de innovación y creatividad, difundiendo y divulgando la producción académica en acceso libre. Sobre este cambio de paradigma versará esta charla académica.
Entrada libre hasta completar aforo.
Una propuesta de Ediciones de la Universidad de Salamanca
Thank you for starting this up. This website is something that is needed on the internet someone with a little originality!
I do not even understand how I ended up here but I assumed this publish used to be great .<a href="https://www.images.google.tn/url?sa=t

Definitely what a great blog and instructive posts I definitely will bookmark your site.All the Best! . – hey dude shoes for women
I recently tried CBD gummies from this website 1500mg cbd gummies as a replacement for the prime prematurely and was pleasantly surprised past the results. Initially skeptical, I create that it significantly helped with my anxiety and sleep issues without any unconcealed side effects. The lubricator was unoppressive to speak, with definite dosage instructions. It had a kindly, vulgar liking that was not unpleasant. Within a week, I noticed a signal improvement in my overall well-being, instinct more serene and rested. I cognizant the natural approach to wellness CBD offers and plan to at using it.
Good post! We will be linking to this particularly great post on our site.
PBN sites
We will create a structure of self-owned blog network sites!
Merits of our self-owned blog network:
We perform everything so GOOGLE does not realize THAT this A PBN network!!!
1- We purchase domain names from separate registrars
2- The primary site is hosted on a virtual private server (Virtual Private Server is rapid hosting)
3- Other sites are on different hostings
4- We attribute a distinct Google profile to each site with verification in Search Console.
5- We develop websites on WP, we do not utilise plugins with assistance from which malware penetrate and through which pages on your websites are created.
6- We do not reproduce templates and utilize only exclusive text and pictures
We refrain from work with website design; the client, if wanted, can then edit the websites to suit his wishes
Understanding COSC Certification and Its Importance in Horology
COSC Certification and its Strict Criteria
COSC, or the Controle Officiel Suisse des Chronometres, is the authorized Swiss testing agency that verifies the accuracy and accuracy of timepieces. COSC accreditation is a sign of quality craftsmanship and dependability in chronometry. Not all watch brands follow COSC validation, such as Hublot, which instead sticks to its own demanding standards with mechanisms like the UNICO, attaining equivalent accuracy.
The Science of Exact Timekeeping
The core mechanism of a mechanical timepiece involves the mainspring, which supplies energy as it unwinds. This mechanism, however, can be prone to external elements that may influence its accuracy. COSC-accredited mechanisms undergo demanding testing—over fifteen days in various conditions (5 positions, three temperatures)—to ensure their resilience and reliability. The tests assess:
Average daily rate precision between -4 and +6 secs.
Mean variation, peak variation levels, and impacts of thermal variations.
Why COSC Validation Matters
For watch aficionados and collectors, a COSC-accredited timepiece isn’t just a piece of technology but a demonstration to lasting excellence and precision. It represents a watch that:
Offers outstanding reliability and precision.
Provides confidence of superiority across the entire design of the timepiece.
Is apt to hold its value more effectively, making it a smart choice.
Well-known Chronometer Manufacturers
Several famous manufacturers prioritize COSC accreditation for their timepieces, including Rolex, Omega, Breitling, and Longines, among others. Longines, for instance, presents collections like the Record and Soul, which highlight COSC-accredited mechanisms equipped with advanced materials like silicon equilibrium suspensions to improve durability and efficiency.
Historic Context and the Development of Timepieces
The concept of the timepiece dates back to the requirement for accurate timekeeping for navigation at sea, emphasized by John Harrison’s work in the 18th century. Since the official establishment of Controle Officiel Suisse des Chronometres in 1973, the validation has become a benchmark for evaluating the accuracy of high-end watches, sustaining a legacy of excellence in watchmaking.
Conclusion
Owning a COSC-validated timepiece is more than an aesthetic choice; it’s a dedication to excellence and precision. For those valuing accuracy above all, the COSC validation provides peacefulness of thoughts, ensuring that each validated watch will operate dependably under various circumstances. Whether for individual satisfaction or as an investment decision, COSC-certified timepieces distinguish themselves in the world of horology, maintaining on a tradition of meticulous timekeeping.
