Photonic crystals PhCs with a degenerate band edge DBE are dispersion-tailored materials composed of a periodic arrangement of misaligned anisotropic dielectric layers and an isotropic dielectric layer. DBE PhCs yield an approximately quartic dispersion relation just below the DBE frequency rather than the conventional quadratic dispersion relation present below a regular band edge RBE . We pre...

Bioremediation has achieved acceptance as a cost-effective technique for the remediation of soils and groundwater contaminated with petroleum hydrocarbons (PHC). A range of laboratory techniques to assess the biodegradability and bioavailability of PHCs are presented. Biodegradability and bioavailability are important determinants of the bioremediation performance of PHCs. Novel methods for the...

Efficient numerical methods for analyzing photonic crystals (PhCs) can be developed using the Dirichlet-to-Neumann (DtN) maps of the unit cells. The DtN map is an operator that takes the wave field on the boundary of a unit cell to its normal derivative. In frequency domain calculations for band structures and transmission spectra of finite PhCs, the DtN maps allow us to reduce the computation ...

Many sites are contaminated with petroleum hydrocarbons (PHCs). In some cases, these PHCs may be biorecalcitrant and therefore the soils contaminated with these PHCs are not amenable to remediation by biological treatment methods. Examples of sites containing biorecalcitrant PHCs are old flare pit sites. Flare pits are earthen pits that were once used for the storage and disposal of natural gas...

Split thickness skin graft (STSG) implantation is one of the standard therapies for full thickness wound repair when full thickness autologous skin grafts (FTG) or skin flap transplants are inapplicable. Combined transplantation of STSG with dermal substitute could enhance its therapeutic effects but the results remain unsatisfactory due to insufficient blood supply at early stages, which cause...

The scarcity of rural physicians in India has resulted in non-physician clinicians (NPC) serving at primary health centers (PHC). This study examines the clinical competence of NPCs and physicians serving at PHCs to treat a range of medical conditions. The study is set in Chhattisgarh state, where physicians (medical officers) and NPCs: Rural Medical Assistants (RMA), and Indian system of medic...

This paper presents a Process History Capture System (PHCS) as a logging mechanism for distributed long running business processes executing over Delta-Enabled Grid Services (DEGS). A DEGS is a Grid Service with an enhanced interface to access incremental data changes, known as deltas, associated with service execution in the context of global processes. The PHCS captures process execution cont...

the mandovi estuary is highly influenced by mining and tourism related activities in the centralwest coast of india. vertical fluxes and accumulation of petroleum hydrocarbons (phcs) in three sedimentcores (d1, c1 and og) from the mandovi estuary were assessed using ultra-violet fluorescence (uvf)spectroscopy. the range of phcs values in estuarine sediments varied from 5.4 to 12.34 μg/g enrichm...

This manuscript focuses on the statistical inference of Kavya–Manoharan generalized exponential distribution under type-I progressive hybrid censoring sample (GTI-PHCS). Different classical approaches estimation, such as maximum likelihood, product spacing, least squares (LS), weighted LS, and percentiles GTI-PHCS, are investigated. Based squared error linear loss functions, Bayes estimates for...

BACKGROUND China has a high burden of diabetes mellitus (DM), and a large proportion of DM patients remain untreated for various reasons, including low availability of primary health care providers. DM patient management is one of the priorities in China's national essential public health programs. Shortage of health workforce has been a major barrier to improving access to health care for DM p...
