Interaction mechanisms of low-level electromagnelic fields in living systems / edited by Bengt Nordön and Claes Romel.

The alteration of release of calcium ions from biological tissue by electromagnetic stimulation has bien reported by several authors (Kaczmarec and Adey 1974:, Bawin et al. 1975, 1978; Bawin and Adey 1976; Blackman et al. 1979, l980a,å; Joines and Blackman 1980, l98l; Joines et al. l98O). Bawin etal. (1975) reported that 147 MHz radiofrequency (RF) electromagnetic radiation altered the release of The 'ion cyclotron resonance hypothesis' was explored by Liboff et al. (1987) in an experiment involving incorporation of calcium-45 (n5Ca2*) in mixed human lymphocytes. The geomagnetic horizontal field component was'adjusted to 2l pT. The experiment was first performed at an amplitude of the applied oscillating field of 150 pT and a sharp minimum was obtained at the frequency of l43Hz, which corr

Challenges and perspectives for improved management of HIV/Mycobacterium tuberculosis co-infection

HIV and Mycobacterium tuberculosis (MTB) are two widespread and highly successful microbes whose synergy in pathogenesis has created a significant threat for human health globally. In acknowledgement of this fact, the European Union (EU) has funded a multinational support action, the European Network for global cooperation in the field of AIDS and TB (EUCO-Net), that brings together experts from E

Safety of device closure of secundum atrial septal defects in children-does the weight at time of procedure matter?

Background: Transcatheter closure of secundum atrial septal defect (ASD) is nowadays the main treatment option in many centers worldwide. In symptomatic infants or in those with certain comorbidities, there is a need for early intervention. Limited data are available about the procedural safety in infants below 15 kg of weight. Methods: Retrospective review of all patients referred to our center f

Impact of Band-Tails on the Subthreshold Swing of III-V Tunnel Field-Effect Transistor

We present a simple model to evaluate the sharpness of the band edges for tunnel field-effect transistors by comparing the subthreshold swing and the conductance in the negative differential resistance region. This model is evaluated using experimental data from InAs/InGaAsSb/GaSb nanowire tunnel-field effect transistors with the ability to reach a subthreshold swing well below the thermal limit.

Role of Community Based Organizations in Transferring Climate Change Information in Rwanda

Background and Objective: Climate change poses a threat for agriculture and development in Rwanda. The agricultural sector in Rwanda is the engine of economic growth and modernization. This study examines the role of community based organizations (CBOs) in transferring climate change information to farmers’ communities in Rwanda. Materials and Methods: Three districts (Kirehe, Rwamagana and Ngoma)
