We modulate temporally the polarization of a ∼ 30 fs, 800 nm IR pulse and use it to generate high order harmonics. The harmonic emission can clearly be confined and the XUV pulse duration can be continuously tuned from - 5 - 7 fs to 50 fs.

We report experimental studies of harmonic generation in Xe using a 1064 nm Nd-YAG laser. Third-harmonic conversion is observed in a positively dispersive medium, using a tight-focusing geometry. The intensity of third-harmonic generation in a gas cell varies much more steeply with the laser intensity than a cubic law. The reason for the breaking of the phase matching condition is discussed.

Ett bra bemötande är en grundförutsättning för en bra vård av såväl personermed långvarig smärta som de utan smärta. Dock är ett vanligt problem attpersoner med långvarig smärta ofta blir misstrodda och personer med långvarig smärta blir oftare illa bemötta än de utan smärta. Av de med långvarig smärta var det omkring en tredjedel som uppgav att de blivit illa bemötta som sökt vård för sin smärta.

This is a prospective pilot investigation of interstitial laser treatment. Twelve patients were treated at 13 sites: seven patients had metastatic or primary liver cancer (with a total of 21 tumour nodules), two had pancreatic carcinoma and four patients had disease at other sites. Treatments mere performed with an Nd-YAG laser, using a high power (6 or 10 W), short-time (5 min) technique or a fee

Training of a new generation of talents capable of working across borders and sectors, with an inclusive approach of food innovation: the case of FIPDes, the ERASMUS mundus joint master’s degree in food innovation and product design.Food innovation applied to sustainable growth is driven by different needs and constraints. Sensory and nutritional aspects of food, as well as convenience are individ

We study the temporal and spectral behaviour of high order harmonics generated by pulses with temporally modulated polarization. We observe a harmonic temporal confinement and a harmonic spectral broadening, compatible with 1 -or-2 attosecond pulse emission.

No prospective randomized study with fracture as end point exists in men. Data from retrospective and prospective observational and case control studies suggest that activity in men is associated with reduced fracture risk. This may be correct, but consistently replicated sampling bias may produce the same observation, as these studies are hypothesis generating, never hypothesis testing. Higher mu

Anorexia nervosa is associated with bone loss during adulthood, but may also delay skeletal growth and mineral accrual during growth. We asked the following questions. 1) Is anorexia nervosa associated with reduced bone size and reduced volumetric bone mineral density (vBMD)? 2) Is estrogen replacement therapy (ERT) or recovery from anorexia nervosa associated with normal bone size and vBMD? Using

This theoretical framework is developed for a research project regarding the specific case of the national policy process for Art and Music Schools in Sweden, a process to create national regulation for the first time in their history. The project focuses on inclusion of every child, but also specifically on inclusion of two particular groups of pupils: pupils in need of special support and refuge

The authors report the observation of very-high-order odd harmonics of Nd:YAG laser radiation in rare gases at an intensity of about 1013 W cm-2. Harmonic light as high as the 33rd harmonic in the XUV range (32.2 nm) is generated in argon. The key point is that the harmonic intensity falls slowly beyond the fifth harmonic as the order increases. Finally, a UV continuum, beginning at 350 nm and ext
