Few studies have focused on home participation of high-functioning children with autism spectrum disorder. We employed a mixed-methods design to explore and compare parent perspectives on (1) participation of children with and without autism spectrum disorder in activities at home, (2) the environmental features and resources that affect these children's home participation and (3) the strategies parents use to help their children participate at home. The Participation and Environment Measure for Children and Youth (PEM-CY) was used to gather online survey and qualitative data from parents of 99 high-functioning children with autism spectrum disorder and 241 children without autism spectrum disorder...

Mechanically robust polymer electrolyte membranes (PEMs) exhibiting high ionic conductivity at ambient temperature are a prerequisite for next-generation electrochemical devices. We utilized a polymerization-induced microphase separation (PIMS) strategy to prepare nanostructured materials comprising continuous conducting nanochannels intertwined with a mechanically and thermally robust cross-linked polymeric framework. Addition of succinonitrile (SN) rendered the poly(ethylene oxide)/lithium (Li) salt conducting domains completely amorphous, resulting in outstanding conductivities (∼0...

Nafion-boron nitride (NBN) nanocomposites with a Nafion-functionalized periphery are prepared via a convenient and ecofriendly Nafion-assisted water-phase exfoliation method. Nafion and the boron nitride nanosheet present strong interactions in the NBN nanocomposite. Then the NBN nanocomposites were blended with Nafion to prepare NBN Nafion composite proton exchange membranes (PEMs). NBN nanocomposites show good dispersibility and have a noticeable impact on the aggregation structure of the Nafion matrix. Connected long-range ionic nanochannels containing exaggerated (-SO3(-))n ionic clusters are constructed during the membrane-forming process via the hydrophilic and H-bonding interactions between NBN nanocomposites and Nafion matrix...

In this study, a series of stationary phases, comprising silica spheres and polyelectrolyte multilayers (PEMs) as the core and surface coating, respectively, were prepared via a layer-by-layer self-assembly approach for use in high-performance liquid chromatography. PEMs coatings were formed by the alternate deposition of positively charged poly(allylamine hydrochloride) and negatively charged poly(ethylene-alt-maleate) anions which were synthesized by esterification between poly(ethylene-alt-maleic anhydride) and n-alkyl alcohols (CnH2n+1OH, n=4, 8, 10, 12)...

Asymmetric cell division during embryogenesis contributes to cell diversity by generating daughter cells that adopt distinct developmental fates. In this chapter, we summarize current knowledge of three examples of asymmetric cell division occurring in ascidian early embryos: (1) Three successive cell divisions that are asymmetric in terms of cell fate and unequal in cell size in the germline lineage at the embryo posterior pole. A subcellular structure, the centrosome-attracting body (CAB), and maternal PEM mRNAs localized within it control both the positioning of the cell division planes and segregation of the germ cell fates...

Microbial fuel cells (MFCs) are emerging technology for wastewater treatment by chemical oxygen demand (COD) reduction and simultaneous bioelectricity production. Fabrication of an effective proton exchange membrane (PEM) is a vital component for MFC performance. In this work, green chitosan-based (CS) PEMs were fabricated with graphene oxide (GO) as filler material (CS-GO) and cross-linked with phosphoric acid (CS-GO-P(24)) or sulfuric acid (CS-GO-S(24)) to determine their effect on PEM properties. Interrogation of the physicochemical, thermal, and mechanical properties of the cross-linked CS-GO PEMs demonstrated that ionic cross-linking based on the incorporation of PO4(3-) groups in the CS-GO mixed-matrix composites, when compared with sulfuric acid cross-linking commonly used in proton exchange membrane fuel cell (PEMFC) studies, generated additional density of ionic cluster domains, rendered enhanced sorption properties, and augmented the thermal and mechanical stability of the composite structure...

The fast and full range measurements of ellipsometric parameters ψ and Δ using a 45° dual-drive symmetric photoelastic modulator (PEM) are proposed. The PEM operates in a pure traveling modulation mode with a constant retardation magnitude and the modulation axis performing circular motion. A field programmable gate array is used to control the PEM and fulfill the data processing. The parameters sin 2ψ sinΔ, sin 2ψ cosΔ, and sin 2ψ can be measured simultaneously, providing accurate measurements of ψ and Δ over the full range...

Off-road vehicles used in construction and agricultural activities can contribute substantially to emissions of gaseous pollutants and can be a major source of submicron carbonaceous particles in many parts of the world. However, there have been relatively few efforts in quantifying the emission factors (EFs) as well as for estimating the potential emission reduction benefits using emission control technologies for these vehicles. This study characterized the black carbon (BC) component of particulate matter and NOx, CO, and CO2 EFs of selected diesel-powered off-road mobile sources in Mexico under real-world operating conditions using on-board portable emissions measurements systems (PEMS)...

Pemetrexed (PEM) is an antimetabolite drug that interferes with enzymes involved in DNA synthesis and also the folate-dependent metabolic processes necessary for DNA replication and homocysteine homeostasis. Continuation maintenance with PEM after induction therapy with PEM plus cisplatin has been the standard form of first-line chemotherapy for advanced non-squamous non-small cell lung cancer. The regimen has a low incidence of bone marrow suppression, and the incidences of anemia, leukopenia, neutropenia and thrombocytopenia exceeding grade 3 are less than 5%...

OBJECTIVE: Acutely ill infants and children presenting to the emergency department are treated by either physicians with pediatric emergency medicine (PEM) training or physicians without PEM training, a good proportion of which are general emergency medicine-trained physicians (GEDPs). This scoping review identified published literature comparing the care provided to infants and children (≤21 years of age) by PEM-trained physicians to that provided by GEDPs. METHODS: The search was conducted in 2 main steps as follows: (1) initial literature search to identify available literature with evolving feedback from the group while simultaneously deciding search concepts as well as inclusion and exclusion criteria and (2) modification of search concepts and conduction of search using finalized concepts as well as review and selection of articles for final analysis using set inclusion criteria...

INTRODUCTION: It is challenging for primary care physicians (PCPs) to review and apply the growing amount of clinical evidence available. Printed educational materials (PEMs), which synthesize evidence, are often ineffective at improving knowledge, possibly due to poor design and limited uptake. In this study, we collected PCP preferences for the design and content of physician-oriented PEMs and determined key attributes that may increase their usability and uptake. METHODS: We held 90-minute focus groups with PCPs in Toronto, ON, Canada...

Multifunctional theranostics have offered some interesting new opportunities for cancer therapy and diagnosis in the last decade. Herein, magnetic mesoporous silica nanoparticles (M-MSNs) were designed and synthesized, then the photosensitizer chlorin e6 (Ce6) and antitumor drug doxorubicin (Dox) were adsorbed onto the M-MSNs. Biocompatible alginate/chitosan polyelectrolyte multilayers (PEM) were assembled on the M-MSNs to achieve a pH-responsive drug delivery system and adsorb P-gp shRNA for reversing the multidrug resistance...

Cost reduction and high efficiency are the mayor challenges for sustainable H2 production via proton exchange membrane (PEM) electrolysis. Titanium-based components such as bipolar plates (BPP) have the largest contribution to the capital cost. This work proposes the use of stainless steel BPPs coated with Nb and Ti by magnetron sputtering physical vapor deposition (PVD) and vacuum plasma spraying (VPS), respectively. The physical properties of the coatings are thoroughly characterized by scanning electron, atomic force microscopies (SEM, AFM); and X-ray diffraction, photoelectron spectroscopies (XRD, XPS)...
