Pre treatment of melatonin rescues cotton seedlings from cadmium toxicity by regulating key physio-biochemical and molecular pathways
( Elsevier , 2023 , Article)Melatonin, a plant/animal origin hormone, regulates plant response to abiotic stresses by protecting them from oxidative damage. This study identified physiochemical and molecular mechanism of melatonin-induced cadmium ... -
Pre-fusion structure of a human coronavirus spike protein
( Nature Publishing Group , 2015 , Article)HKU1 is a human betacoronavirus that causes mild yet prevalent respiratory disease1, and is related to the zoonotic SARS2 and MERS3 betacoronaviruses, which have high fatality rates and pandemic potential. Cell tropism ... -
Pre-prandial plasma liver-expressed antimicrobial peptide 2 (LEAP2) concentration in humans is inversely associated with hunger sensation in a ghrelin independent manner
( Springer Science and Business Media Deutschland GmbH , 2023 , Article)Purpose The liver-expressed antimicrobial peptide 2 (LEAP2) is a newly recognized peptide hormone that acts via the growth hormone secretagogue receptor (GHSR) blunting the effects of ghrelin and displaying ghrelin-independent ... -
Pre-service Teachers' Perception of their Educational Preparation
(2020 , Master Thesis)The present study aims at investigating pre-service teachers’ perception of their educational preparation in three post-graduate diploma programs at Qatar University College of Education. A questionnaire consisting of ... -
Pre-symptomatic and asymptomatic transmission of COVID-19: Implications for control measures in Qatar
( QSCIENCE , 2021 , Article)Public health control measures for communicable diseases are often based on the identification of symptomatic cases. However, emerging epidemiological evidence demonstrates the role of presymptomatic and asymptomatic ... -
Pre-Transit Oriented Development Assessment Guidelines for Assessing Metro Station Dependent Component Area
( MDPI , 2022 , Article)Transit-Oriented Development (TOD) assessment models are commonly used to assess existing and planned metro station catchment areas. Elements like diversity, density, design, destination, distance, and demand management ... -
Precious metal free Ni/Cu/Mo trimetallic nanocomposite supported on multi-walled carbon nanotubes as highly efficient and durable anode-catalyst for alkaline direct methanol fuel cells
( Elsevier B.V. , 2018 , Article)Direct methanol fuel cells (DMFCs) proved to be an auspicious choice in the applications of portable power electronics and energy transportation, apart from their high cost catalysts materials. To this end, we have developed ... -
Precise and insufficient scientific endeavour: COVID-19 pandemic experience from Bosnia and Herzegovina
( Edinburgh University Global Health Society , 2023 , Article)The coronavirus 2019 (COVID-19) pandemic has exacted a heavy burden for healthcare systems and medical professionals globally. Countries with a substantial portion of unvaccinated populations face difficulties in defending ... -
Precise fabrication of porous one-dimensional gC3N4 nanotubes doped with Pd and Cu atoms for efficient CO oxidation and CO2 reduction
( Elsevier B.V. , 2019 , Article)Rational design of graphitic carbon nitride nanostructures (gC3N4) is vital for various catalytic applications. Herein, we synthesized porous gC3N4 nanotubes (gC3N4NTs) doped with Pd and Cu (Pd/Cu/gC3N4NTs) via the consecutive ... -
Precise method for linearizing sine and cosine signals in resolvers and quadrature encoders applications
( IEEE , 2004 , Conference Paper)Resolvers and quadrature encoders provide electrical signal related to the sine and cosine of the mechanical shaft angle over the full 360 degree range. A converter is described for the linearization of these signals, ... -
Precise, wide-range approximations to arc sine function suitable for analog implementation in sensors and instrumentation applications
( IEEE , 2005 , Article)This paper presents four newly developed algebraic approximations of the inverse sine function, defined for the full [-1,+1] input range. These approximations contain few terms, and have numerical coefficients with low ... -
