Due to the significant increase in pediatric trunk computed tomography (CT) examinations, there is a need for a reliable approach of conducting effectivedose estimate for such procedures. The current study is based on two dosimetric anthropomorphic phantoms representing a 1-year and a 5-year old child. Effectiveand equivalent tissue doses from CT examinations of the trunk were determined by thermo

One of the intensively explored domains of the current bionanotechnology is the focus for search of nano-materials intended to develop high throughput electronic devices. Among the questioned physical materials deoxyribonucleic acid (DNA) has given promising background to be explored as potential nanowire material for aspiring nano-devices. The distinguished characteristics of electron hopping bet

Transfer integrals for oligos with different bases have been calculated using INDO/Koopman's approximation to unveil the charge transport mechanism in DNA. The sequences, G(A)nG, n = 1, 2, …, 10; G(A)xG(A)yG, x + y = 9; and G(A)xG(A)yG(A)zG, x + y + z = 8, were employed to interpret the Guanine (G) and Adenine(A) hopping. Adenine hopping is found to be faster in G(A)nG sequences with longer Adenin

Optically stimulated luminescence (OSL) from ordinary household salt has proven high potential for very low dose retrospective dosimetry. In the present paper other common place materials are considered and their dosimetric OSL-properties compared with household salt. The potential for assessment of the effective dose to an individual carrying such materials is investigated.

Having previously demonstrated that in-patients referred to neurology at two UK hospitals were not fully examined prior to referral, we designed an audit with 80% power to detect a 10% increase in tendon hammer or ophthalmoscope use following an educational intervention. In-patients referred to neurology over a 4 month period in the UK, Jordan, Sweden and the United Arab Emirates were asked whethe

Establishing diagnostic reference levels (DRLs) in a big country is complicated due to differences in radiological practice between different regions. In 2009-2014, a dose survey was performed in six Russian regions. Based on the results of the survey, preliminary DRLs for conventional X-ray examinations were established on a national level. Additionally, the local authorities were granted the pos

Covalent attachment of biomolecules to the surface of carbon nanotubes provides an architecture for three dimensional arrays of sensor molecules (i.e. enzymes) for potential biosensor application. Present work reports a simple two-step reaction for immobilization of glucose oxidase on single walled carbon nanotubes (SWCNTs). This method is as efficient as conventional methods for biofunctionalizat

In the present manuscript, current-voltage (I-V) measurements of double stranded guanine rich sequences of λ-DNA have been reported. These sequences show length dependent conductivity. Conductivity (σ0) DNA of length, L = 0.6494 x 10-4 (1910 bp), 1 x 10-4 (2947 bp) and 1.3498 x 10-4 cm (3970 bp) was found to be 2.4 x 105, 7.7 x 102 Ω-1cm-1 and insulator behavior, respectively. I-V characterization

Aims: To illustrate the importance of access to register data on determinants and predictors of study participation to assess validity of population-based studies. In the present investigation, we use data on sociodemographic conditions and disease history among individuals invited to the Swedish cardiopulmonary bio-image study (SCAPIS) in order to establish a model that predicts study participati

Global health diplomacy (GHD) focuses on international negotiation; principally between nation states, but increasingly non-state actors However, agreements made at the global level have to be enacted at the national, and in some cases the sub-national level. This presents two related problems: (1) how can success be measured in global health diplomacy and (2) at what point should success be evalu

Complex security environments are characterized by violence (including, but not limited to "armed conflict" in the legal sense), poverty, environmental disasters and poor governance. Violence directly affecting health service delivery in complex security environments includes attacks on individuals (e.g. doctors, nurses, administrators, security guards, ambulance drivers and translators), obstruct

BACKGROUND: Previous analyses concerning health components of European Union (EU)-funded research have shown low project participation levels of the 12 newest member states (EU-12). Additionally, there has been a lack of subject-area analysis. In the Health Research for Europe project, we screened all projects of the EU's Framework Programmes for research FP5 and FP6 (1998-2006) to identify health

OBJECTIVE: European Union (EU) information from research projects, including key findings, should be available on the European Commission's Community Research and Development Information Service (CORDIS) database. We describe the results of the Health Research for Europe (HR4E) project which aimed to synthesize results of health research from the EU's Fifth and Sixth Framework Programmes (FP5 and

Background: Differentiated thyroid cancer (TC) is the most common endocrine cancer. Fish can be an important source of iodine and other micronutrients and contaminants that may affect the thyroid gland and TC risk. Objective: We prospectively evaluated the relations between the consumption of total fish and different fish types and shellfish and TC risk in the EPIC (European Prospective Investigat

We study spectral properties of the Neumann–Poincaré operator on planar domains with corners with particular emphasis on existence of continuous spectrum and pure point spectrum. We show that the rate of resonance at continuous spectrum is different from that at eigenvalues, and then derive a method to distinguish continuous spectrum from eigenvalues. We perform computational experiments using the
