In this paper, one-dimensional (1D) and two-dimensional (2D) graphene-based plasmonic photonic crystals (PhCs) are proposed. The band structures and density of states (DOS) have been numerically investigated. Photonic band gaps (PBGs) are found in both 1D and 2D PhCs. Meanwhile, graphene-based plasmonic PhC nanocavity with resonant frequency around 175 THz, is realized by introducing point defe...

Non-medical characteristics of primary healthcare centres (PHCs) influence the prescription of temporary disability leaves (incidence and absence rates) due to anxiety, as studied in the Valencian Community (E Spain; 5,111,706 inhabitants, 2009), where 485 centres (66%) were analysed. A structural two-equation model was used to explain which centres’ factors impact prescriptions more. This mode...

Eight to 10% of children in Sweden have asthma. The majority of these children are followed and treated in primary health care centers (PHCs). Many studies show poor compliance to written guidelines [1,2]. The purpose of this study was to evaluate whether or not the method of interactive case-based education [3] combined with audit/feedback [4], leads to a better quality of care for children wi...

For a photonic crystal (PhC) of finite size, it is important to calculate its transmission and reflection spectra. For two-dimensional (2-D) PhCs composed of a square lattice of circular cylinders, the problem can be solved by an efficient method based on the Dirichletto-Neumann (DtN) map of the unit cell and a marching scheme using a pair of operators. In this paper, the DtN operator marching ...

BACKGROUND Korea saw a sharp increase in HIV diagnosis from 2000. This serious public health concern must be monitored diligently. We identified the characteristics and trends in HIV prevalence among visitors to public health centers (PHCs) from 2000 to 2009. METHODS We retrieved ten-year data of HIV tests from 253 PHCs. The HIV prevalence was analyzed by gender, age, nationality, region, and...

BACKGROUND Adjusted clinical groups (ACG®) have been widely used to adjust resource distribution; however, the relationship with effectiveness has been questioned. The purpose of the study was to measure the relationship between efficiency assessed by ACG® and a clinical effectiveness indicator in adults attended in Primary Health Care Centres (PHCs). METHODS RESEARCH DESIGN cross-sectiona...

Expression of virulence factors in Ralstonia solanacearum is controlled by a complex regulatory network, at the center of which is PhcA, a LysR family transcriptional regulator. We report here that expression of phcA and production of PhcA-regulated virulence factors are affected by products of the putative operon phcBSR(Q). phcB is required for production of an extracellular factor (EF), tenta...

This research was for "Influence of Applying Preventive Health Conditions Strategy (PHCS) during Coronavirus Pandemic (CVP) in Kingdom Saudi Arabia (KSA)". The target through questionnaire to individuals KSA. That application PHCS and persons contribution accountable establishments, cover infection (CVI), caused CVP control redact it, numbers maintain health (SH). Using "Cross-sectional Study M...

Recently, tunable photonic crystals (PhCs) have received great research interest, thanks to the wide range of applications in which they can be employed, such as light emission and sensing, among others. In addition, versatility ease fabrication PhCs allow for integration a large responsive elements that, turn, permit active tuning PhC optical properties upon application external stimuli, e.g.,...

Background: Health workers are considered to be credible people in health the field; they often deemed as role models healthy behavior. Primary healthcare centers (PHCs) and professional organizations (PHOs) have support (HWs) order that perform their duty according codes of work ethics. Aims: This study aimed investigate from PHCs PHOs for HWs community. Methods: is an exploratory qualitative ...
