Patellar tendon moment arm length (PTma) changes at different knee flexion angles have not been determined in invivo studies. We aimed to determine PTma in four different knee angles using Magnetic Resonance Imaging (MRI) topredict in vivo changes in the moment arm length from different knee angles during running.PTma was measured as the perpendicular distance from muscle–tend...

An organic bifunctional catalyst poly(2,2,6,6-tetramethylpiperidinyloxy-4-yl methacrylate) (PTMA) has been prepared and coated on carbon surface during electrode preparation. The PTMA has been applied as an efficient bifunctional catalyst for lithium-oxygen batteries with lower overpotentials, enhanced rate performances, and prolonged cycle life.

is analyzing the condition of ecosystem services in Portugal, recent trends in those services, available policy responses, and scenarios for the next fifty years, following the conceptual framework of the Millennium Ecosystem Assessment (MA) (Millennium Ecosystem Assessment 2003). It is a multiscale assessment, carried out at the national, basin, and local scales. The assessment started in 2003...

Investigation of the transmission of magnetic interactions through hydrogen bonds has been carried out for two different benzoic acid derivatives which bear either a tert-butyl nitroxide (NOA) or a poly(chloro)triphenylmethyl (PTMA) radical moiety. In the solid state, both radical acids formed dimer aggregates by the complementary association of two carboxylic groups though hydrogen bonding. Th...

Percutaneous transvenous mitral annuloplasty (PTMA) has evolved as a latest procedure for the treatment of functional mitral regurgitation. It reduces mitral valve annulus (MVA) size and increases valve leaflet coaptation via compression of coronary sinus (CS). Anatomical considerations for this procedure were elucidated in the present study. In 40 formalin fixed adult cadaveric human hearts, r...

Organic photovoltaic (OPV) devices based on the copper (II) phthalocyanine(CuPc)/ fullerene(C60) system are an innovative photovoltaic technology optimal for situations requiring low-cost, transparent, and flexible devices. Furthermore, the high degree of reproducibility of this system allows for the ready study of new OPV technologies. Here, we have used this system to elucidate systematic str...

High energy and high power electrochemical energy storage devices rely on different fundamental working principles--bulk vs. surface ion diffusion and electron conduction. Meeting both characteristics within a single or a pair of materials has been under intense investigations yet, severely hindered by intrinsic materials limitations. Here, we provide a solution to this issue and present an app...

To evaluate the role of estrogen receptor in the differentiation of cells of neural origin, we developed a molecular approach aimed at the identification of estrogen target genes by mRNA differential display PCR (ddPCR) in human neuroblastoma SK-ER3 cells. More than 3000 RNAs were examined, a few of which displayed a differential regulation pattern in response to 17beta-estradiol (E2). Sequence...

Maritime transportation market relies on a diverse set of stakeholders and it is strongly affected by their cultural and sectoral diversity. The plethora of existing telematic information services suffer from inflexibility in the sense of restricting the types of business models they allow. Thus the providers of such services are forced to assume predefined business models and processes that ar...

Vollorganische Batterien auf Grundlage redoxaktiver Polymere versprechen eine Alternative zu Lithium-Ionen-Batterien für die nachhaltige Energiespeicherung werden. tragen bisher als Elektroden oder feste Elektrolyte zum Ziel einer rein organischen Zelle bei. Hier ersetzen wir den Elektrolyten durch ein Deep Eutectic Solvent (DES), das aus Natriumbis(trifluormethansulfonyl)imid (NaTFSI) und N-Me...
