Searches for lepton number violation and resonances in K± → πμμ decays

2017

The NA48/2 experiment at CERN collected a large sample of charged kaon decays to final states with multiple charged particles in 2003–2004. A new upper limit on the rate of the lepton number violating decay K±→π∓μ±μ± is reported: B(K±→π∓μ±μ±)<8.6×10−11 at 90% CL. Searches for two-body resonances X in K±→πμμ decays (such as heavy neutral leptons N4 and inflatons χ ) are also presented. In the absence of signals, upper limits are set on the products of branching fractions B(K±→μ±N4)B(N4→πμ) and B(K±→π±X)B(X→μ+μ−) for ranges of assumed resonance masses and lifetimes. The limits are in the (10−11,10−9) range for resonance lifetimes below 100 ps.

Voimaharjoittelun ja proteiinisupplementaation vaikutus myostatiinin ja siihen liittyvien geenien ilmentymiseen nuorilla ja vanhoilla miehillä

2008

Salmijärvi, Hanna 2008. Voimaharjoittelun ja proteiinisupplementaation vaikutus myostatiinin ja siihen liittyvien geenien ilmentymiseen nuorilla ja vanhoilla miehillä. Liikuntafysiologian Pro gradu – tutkielma. Jyväskylän yliopisto. Liikuntabiologian laitos, 80s. Myostatiini vaikuttaa luurankolihasten kasvuun negatiivisesti pääasiallisesti estämällä satelliittisolujen kypsymistä ja erilaistumista. Hypertrofiaolosuhteissa satelliittisolut jakautuvat ja luovuttavat lihassoluihin uusia tumia. Myogeeniset säätelytekijät MyoD ja myogeniini säätelevät satelliittisolujen kypsymistä ja erilaistumista. Riittävä proteiinien saanti on hypertrofialle välttämätöntä fyysisen suorituksen yhteydessä. Ikään…

Miten lihas kasvaa?

2018

Lihakset aistivat kuormitusta ja muokkautuvat rasitukseen. Perimä ja se miten geenimme ilmentyvät vaikuttavat merkittävästi lihaskokoon. Lihassolumme pystyvät kuitenkin mukautumaan kulloisiinkin olosuhteisiin, kuten ravitsemustilaan ja fyysiseen aktiivisuuden tasoon. nonPeerReviewed

Complex dynamics, hidden attractors and continuous approximation of a fractional-order hyperchaotic PWC system

2018

In this paper, a continuous approximation to studying a class of PWC systems of fractionalorder is presented. Some known results of set-valued analysis and differential inclusions are utilized. The example of a hyperchaotic PWC system of fractional order is analyzed. It is found that without equilibria, the system has hidden attractors.

Estudio piloto del tratamiento del liquen escleroso vulvar mediante tejido adiposo asociado a plasma rico en plaquetas autólogos

2020

Estudio piloto del tratamiento del liquen escleroso vulvar mediante tejido adiposo asociado a plasma rico en plaquetas autólogo. 1. Introducción. El Liquen escleroso (LE) es una enfermedad inflamatoria crónica, mediada por Linfocitos T (LT), de etiología desconocida que afecta fundamentalmente a la piel genital. Aunque La etiología exacta del LE es desconocida, se considera una enfermedad de origen multifactorial y cada vez se aboga más por el mecanismo autoinmune basado en su asociación con otras enfermedades de este tipo (Tiroiditis Hashimoto, alopecia Areata, vitíligo y anemia perniciosa) hasta en un 21-28% de los casos. La prevalencia en la población general se estima en 1 de cada 300-1…

Recent Progress in the WCLL Breeding Blanket Design for the DEMO Fusion Reactor

2018

The water-cooled lithium-lead (PbLi) breeding blanket is one of the candidate systems considered for the implementation in the European Demonstration Power Plant (DEMO) nuclear fusion reactor. This concept employs PbLi liquid metal as tritium breeder and neutron multiplier, water pressurized at 15.5 MPa as the coolant, and EUROFER as the structural material. The current design is based on the single module segment approach and follows the requirements of the DEMO-2015 baseline design. The module is constituted by a basic toroidal-radial cell that is recursively repeated along the poloidal direction where the liquid metal flows along a radial-poloidal path. The heat generated by the fusion r…

Development of ultrasound-assisted digestion methods for the determination of toxic element concentrations in ash samples by ICP-OES

2011

The present thesis introduces several ultrasound-assisted digestion methods developed for the determination of toxic element concentrations in ash samples by inductively coupled plasma optical emission spectrometry (ICP-OES). Ultrasound-assisted digestion is a quite new technique used for sample pre-treatment purposes, especially in difficult sample matrixes. Elements determined are As, Ba, Co, Cr, Cu, Ni, Pb, Sb, Sr, V, and Zn. Most of the elements determined exist at a trace or ultra trace level in ashes and most are potential risks in the environment or human body even at low concentrations. Most of the selected elements can be determined directly by ICP-OES, but for the determination of…

Magnetoelectric effects in superconductor/ferromagnet bilayers

2018

We demonstrate that the hybrid structures consisting of a superconducting layer with an adjacent spin-textured ferromagnet demonstrate the variety of equilibrium magnetoelectric effects originating from coupling between the conduction electron spin and superconducting current. By deriving and solving the generalized Usadel equation which takes into account the spin-filtering effect we find that a supercurrent generates spin polarization in the superconducting film which is non-coplanar with the local ferromagnetic moment. The inverse magnetoelectric effect in such structures is shown to result in the spontaneous phase difference across the magnetic topological defects such as a domain wall …
