Misconceptions about PPRS

open access: yesBMJ, 2007
Iheanacho argues that the Office of Fair Trading may have pinpointed some areas of improvement in the existing Pharmaceutical Price Regulation Scheme (PPRS).1 However, its proposals for introducing a value based system of drug pricing are inherently flawed and, if implemented, would lead to a significant erosion of …

Highlighting That Green Products Derive From Waste: Which Is the Effect on Consumer Behavioral Intention?

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT In the current market landscape, many innovative eco‐friendly materials are being developed. Plant‐based leather is being used recently in the production of fashion accessories. Based on the rational perspective in explaining sustainable consumer behavior, this study investigates the effect of green perceived utility, perceived performance ...

Genome-wide analysis of the pentatricopeptide repeat gene family in different maize genomes and its important role in kernel development

open access: yesBMC Plant Biology, 2018
Background The pentatricopeptide repeat (PPR) gene family is one of the largest gene families in land plants (450 PPR genes in Arabidopsis, 477 PPR genes in rice and 486 PPR genes in foxtail millet) and is important for plant development and growth. Most

Effects of Magnetic Fields on String Pair Creation

open access: yes, 2000
The rate of pair production of open strings in general uniform electromagnetic fields is calculated in various space-time dimensions. The corrections with respect to the case of pure electric backgrounds are displayed.

Analytic philosophy, 1925-1969: emergence, management and nature [PDF]

open access: yes, 2018
This paper shows that during the first half of the 1960s The Journal of Philosophy quickly moved from publishing work in diverse philosophical traditions to, essentially, only publishing analytic philosophy. Further, the changes at the journal are shown,

An assessment of stress and production rate of sucker rod heat pipes in oil well pumping system

open access: yesDeep Underground Science and Engineering, EarlyView.
The sucker rod pumping system is the preferred oil extraction technique. The concept about equipping the hollow vacuum space in solid sucker rods with heat pipe has been scrutinized in terms of stress and oil production evaluation. Abstract The implementation of the heat pipe concept in sucker rods for oil pumping systems negates the requirement for an

Sequence analysis of two alleles reveals that intra-and intergenic recombination played a role in the evolution of the radish fertility restorer (Rfo)

open access: yesBMC Plant Biology, 2010
Background Land plant genomes contain multiple members of a eukaryote-specific gene family encoding proteins with pentatricopeptide repeat (PPR) motifs.

Seeded PageRank Solution Paths

open access: yes, 2015
We study the behavior of network diffusions based on the PageRank random walk from a set of seed nodes. These diffusions are known to reveal small, localized clusters (or communities) and also large macro-scale clusters by varying a parameter that has a ...

Sustainable Optimization of Emissions and Performance in Hydrogen Port Injection Diesel Engines Through Port Timing and Injection Duration Modulation

open access: yesEnergy Science &Engineering, EarlyView.
Optimizing hydrogen port injection in diesel engines significantly improves efficiency and reduces emissions, demonstrating a sustainable dual‐fuel strategy for cleaner transportation solutions and lower environmental impact. ABSTRACT This study evaluates a single‐cylinder hydrogen port injection (HPFI) Diesel engine by systematically varying the ...

Superior through‐plane thermal conductivity in carbon fibers/spherical graphene/epoxy laminated composites for low‐altitude aircrafts

open access: yesInfoMat, EarlyView.
To address the low through‐plane thermal conductivity (λ⊥) of carbon fiber/epoxy composites, which poses thermal management challenges in the expanding low‐altitude economy, we incorporated spherical thermally reduced graphene (s‐TRG) as a bridging filler. This architectural design achieved a λ⊥ of 2.73 W m–1 K–1 at 10 wt% loading.
