Wpływ stanu napięcia mięśni dna miednicy na ocenę poziomu zaburzeń erekcji i nietrzymania moczu u osób po prostatektomii radykalnej. Doniesienie wstę…

2017

Celem pracy była ocena, jak napięcie mięśni dna miednicy (MDM) mierzonego za pomocą sEMG wpływa na ocenę obiektywną i subiektywną trzymania moczu oraz zaburzeń erekcji. W badaniach uczestniczyło 10 mężczyzn, będących po zabiegu prostatektomii. Nasilenie objawów nietrzymania moczu oceniano na podstawie kwestionariusza ICIQ-SF, aktywność seksualną kwestionariuszem IIEF-5. Nie wykazano istotnego statystycznie związku między napięciem MDM, ocenianego za pomocą sEMG, a obiektywnymi wyznacznikami nietrzymania moczu, jednakże zaobserwowano tendencję, że niższe napięcie MDM występuje częściej u chorych ze wszystkimi dolegliwościami w ocenie subiektywnej.

Impact of intermittent energy restriction on anthropometric outcomes and intermediate disease markers in patients with overweight and obesity: system…

2020

This systematic review aims to investigate the effects of intermittent energy restriction (IER) on anthropometric outcomes and intermediate disease markers. A systematic literature search was conducted in three electronic databases. Randomized controlled trials (RCTs) were included if the intervention lasted ≥12 weeks and IER was compared with either continuous energy restriction (CER) or a usual diet. Random-effects meta-analysis was performed for eight outcomes. Certainty of evidence was assessed using GRADE. Seventeen RCTs with 1328 participants were included. IER in comparison to a usual diet may reduce body weight (mean difference [MD]: −4.83 kg, 95%-CI: −5.46, −4.21; n = 6 RCTs), wais…

Late Quaternary sedimentary evolution of the Castellammare Gulf (North-Western Sicily offshore)

2005

High-resolution seismic stratigraphy has been applied to the interpretation of the stratigraphic architecture of Late Pleistocene and Holocene successions on the continental shelf and upper slope of the Gulf of Castellammare, North-Western Sicily. The Late Quaternary type 1 depositional sequence is bounded by a regional unconformity and it is made up of four systems tracts, developed under fourth order relative sea level fluctuations, after the previous highstand of isotope Stage 5e. Systems tract are located in different parts of the basin, two being confined to the outer shelf and the upper slope, the other developed along the inner shelf. Facies associations, geomorphological elements, a…

Analysing students’rating of the SLP Digitally Competent Educators

2021

This article uses student feedback to examine the perspective of participants in the short learning programme (SLP) pilot Digitally Competent Educators (DCE). This SLP was targeted at the continuous professional development and lifelong learning for educators at various levels and several education areas. Student feedback was collected in 2020 using anonymous surveys at the end of each course. This implies that respondents were those participants who completed the course. Feedback, used on further development of the SLP, focused on the content and implementation of the course modules. The SLP followed the design guidelines produced inside the E-SLP project and was based on the Digital Compe…

Temporal spying and concealing process in fibre-optic data transmission systems through polarization bypass

2014

Recent research has been focused on the ability to manipulate a light beam in such a way to hide, namely to cloak, an event over a finite time or localization in space. The main idea is to create a hole or a gap in the spatial or time domain so as to allow for an object or data to be kept hidden for a while and then to be restored. By enlarging the field of applications of this concept to telecommunications, researchers have recently reported the possibility to hide transmitted data in an optical fibre. Here we report the first experimental demonstration of perpetual temporal spying and blinding process of optical data in fibre-optic transmission line based on polarization bypass. We succes…

Efficient interrogation method of forward Brillouin scattering in optical fibers using a narrow bandwidth long-period grating

2020

A new technique, to the best of our knowledge, for the characterization of the effective refractive index modulation in optical fibers due to transverse acoustic mode resonances excited by electrostriction is reported. The resonances excited by an optical pulse are probed by a narrow bandwidth long-period grating (LPG) inscribed in the fiber, which is interrogated by a continuous wave (CW) beam. The LPG used in this experiment has a narrow bandwidth and high sensitivity to small mode index perturbations, allowing the measurement of index variations from below 10 − 9 to 10 − 6 . Radial and torsional-radial acoustic modes were characterized up to 1.1 GHz. The linewidth of resonances was found…

A universal optical all-fiber omnipolarizer

2012

International audience; Wherever the polarization properties of a light beam are of concern, polarizers and polarizing beamsplitters (PBS) are indispensable devices in linear-, nonlinear- and quantum-optical schemes. By the very nature of their operation principle, transformation of incoming unpolarized or partially polarized beams through these devices introduces large intensity variations in the fully polarized outcoming beam(s). Such intensity fluctuations are often detrimental, particularly when light is post-processed by nonlinear crystals or other polarization-sensitive optic elements. Here we demonstrate the unexpected capability of light to self-organize its own state-of-polarizatio…

Measurement of the soliton number in guiding media through continuum generation.

2020

No general approach is available yet to measure directly the ratio between chromatic dispersion and the nonlinear coefficient, and hence the soliton number for a given optical pulse, in an arbitrary guiding medium. Here we solve this problem using continuum generation. We experimentally demonstrate our method in polarization-maintaining and single-mode fibers with positive and negative chromatic dispersion. Our technique also offers new opportunities to determine the chromatic dispersion of guiding media over a broad spectral range while pumping at a fixed wavelength.
