We study the effective field theory (including operators up to dimension five) of models in which dark matter is composite, consisting either an electroweak doublet Dirac fermion (`higgsino-like matter') or triplet Majorana (`wino-like matter'). Some dimension-five former case cause mass splittings between neutralino and chargino states, leading a depleted rate coannihilations viable thermal re...

OBJECTIVES To evaluate the efficacy of transcutaneous electrical nerve stimulation (TENS) as analgesia during colonoscopy. DESIGN In a randomised controlled trial, patients undergoing diagnostic colonoscopy were assigned to one of three groups: standard medication only (midazolam); active TENS plus standard medication; or non-functioning TENS and standard medication. Efficacy of TENS was dete...

Transcutaneous electrical nerve stimulation (TENS) is accepted in the treatment of chronic pain, even if the mechanism of therapeutical dynamics is not known exactly up to now. The value of TENS in the treatment of headache, particularly vascular headache is discussed controversially. Several studies indicate that the efficacy of TENS can be measured by means of quantitative evaluation, and dif...

Efficient spectral and pseudospectral algorithms for simulation of linear and nonlinear 3D whistler waves in a cold electron plasma are developed. These algorithms are applied to the simulation of whistler waves generated by loop antennas and spheromak-like stationary waves of considerable amplitude. The algorithms are linearly stable and show good stability properties for computations of nonli...

BACKGROUND Transcutaneous nerve stimulation (TENS) has been proposed as a means of reducing pain in labour. The TENS unit emits low-voltage electrical impulses which vary in frequency and intensity. During labour, TENS electrodes are generally placed on the lower back, although TENS may be used to stimulate acupuncture points or other parts of the body. The physiological mechanisms whereby TENS...

Transcutaneous electrical nerve stimulation (TENS) is a non-invasive analgesic technique that is used to relieve nociceptive, neuropathic, and musculoskeletal pain. During TENS, pulsed electrical currents are generated by a portable pulse generator and delivered across the intact surface of the skin via the selfadhering conducting pads called electrodes (Fig. 1). Patients can self-administer TE...

MAGIC [2] is currently the world largest air Cherenkov telescope. MAGIC has been constructed to study sources of very high energy γ–rays (VHE–γ) in the energy range from a few tens of GeV up to a few tens of TeV. In the experiment, γ–rays are detected indirectly by collecting Cherenkov photons which are emitted in a VHE–γ induced electromagnetic cascade in the atmosphere. For a more comprehensi...

OBJECTIVE To determine the hypoalgesic effects of transcutaneous electrical nerve stimulation (TENS) parameter combinations on experimental models in healthy humans. METHODS Searches were performed using the electronic databases Ovid MEDLINE, CINAHL, AMED, and Web of Science (from inception to December 2009). Manual searches of journals and reference lists of retrieved trials were also perfor...

Introdução: Câncer é o nome dado a um conjunto de mais 100 doenças que têm em comum crescimento desordenado células com capacidade invadir tecidos e órgãos à distância. O câncer pode trazer ao paciente experiências quadros álgicos. Atualmente eletroterapia na fisioterapia recurso bem estabelecido prática clínica benefícios indiscutíveis, entretanto, sua aplicação pacientes oncológicos ainda pou...
