Physiotherapy management of patients with coronary artery disease: a report on current practice in South Africa
Authors: Roos R. , Van Aswegen H. 
Published: June 2017

Coronary artery disease (CAD) is a worldwide health problem with an increased prevalence in sub-Saharan Africa. Physiotherapists inter-nationally are involved in the care of these patients from the acute stage following a cardiac event until phase III cardiac rehabilitation is completed. The purpose of this study was to determine the current physiotherapy management of patients with CAD in South Africa. An observational cross-sectional study was conducted over two months with a questionnaire that was sent to the government and private health care sectors. Results showed that more cardiopulmonary physiotherapists provided care (62%) than those who didn’t (38%). Care was mostly provided in a hospital setting (81%) and out- patient phase III cardiac rehabilitation was lacking (11%). In-hospital physiotherapy treatment was mostly provided once daily. Deep breathing exercises (99%), circulatory exercises (95%) and manual chest clearance techniques (88%) were mostly used during physiotherapy. Evidence based practice was consistent regarding early mobilization but was inconsistent with regards to the use of manual chest clearance techniques.

ESTUDO DO MELHORAMENTO DO PONTO DE ENTUPIMENTO DE FILTRO A FRIO DO BIODIESEL DE SEBO A PARTIR DA ADIÇÃO DE AGENTES SURFACTANTES E ANTICONGELANTES USANDO PLANEJAMENTO DE EXPERIMENTOS
Authors: Fortunato Gilson Roberto , Flumignan Danilo Luiz 
Published: June 2017

O Programa Nacional de Produção e Uso de Biodiesel (PNPB) é um programa interministerial do Governo Federal que apesar de iniciado com certa prudência, envolvendo a adição de apenas 2% de biodiesel ao diesel mineral, em caráter autorizativo, utilizando o expediente de leilões para configurar uma demanda real, o programa acabou superando suas metas e passa a estabelecer objetivos maiores, com a introdução até mesmo do B10. Por outro lado, à medida que o tema se desenvolve, os desafios aumentam para atender a demanda, a exemplo do biodiesel de sebo que tem um número de cetano superior, não compete com a área de alimentos, seu ponto de fulgor é maior e é muito mais estável termicamente que o biodiesel de soja, porém seu ponto de entupimento é muito alto próximo a 12 ºC, acarretando em congelamento em vias de transporte em dias mais frios. Este trabalho pretende apresentar como proposta o melhoramento da temperatura do ponto de entupimento de filtro a frio do biodiesel de sebo através da adição de agente surfactante e agente anticongelante. Com este estudo pretende-se agregar valores de sustentabilidade à cadeia brasileira de biocombustíveis, além de melhorar o seu armazenamento em unidades de processamento de biodiesel. PALAVRAS-CHAVE: ponto de entupimento de filtro a frio, biodiesel de sebo, surfactante, anticongelante.
OBTENÇÃO DE BIODIESEL A PARTIR DOS ÓLEOS DE MACAÚBA, BABAÇU E DENDÊ, UTILIZANDO DIFERENTES CATALISADORES QUÍMICOS E BIOLÓGICOS

Published: June 2017

O trabalho almeja analisar as diferenças entre os métodos de obtenção do biodiesel à partir dos óleos vegetais de Babaçu (Orbignya phalerata), Macaúba (Acrocomia aculeata) e Dendê (Elaeis guineensis), os quais desempenham importante papel uma vez que são matérias-primas renováveis para a produção de biodiesel e, diante dessa característica são mais facilmente degradados pela natureza em comparação aos combustíveis fósseis, além de diminuição das emissões gasosas poluentes quando queimados em motores ciclodiesel. Para tanto, realizou-se em laboratório a transesterificação dos ésteres presentes nesses óleos utilizando os catalisadores hidróxido de potássio (KOH) e Creon 25000© (enzima) e posterior análise do produto obtido por meio do método de cromatografia em camada delgada. Realizou-se alguns ensaios de análise das propriedades físico- químicas para verificar a maior eficácia de catalisador químico (KOH) em detrimento ao biológico.

Meer rendement halen uit investeringen in een betere beleidsvoorbereiding
Een gedegen beleidsvoorbereiding kan beleidsfalen voorkomen. Hoewel deze thematiek al jaren aandacht krijgt in de politiek, lukt het de rijksoverheid nog niet hieraan structureel succesvol invulling te geven. In het licht van de recente Tweede Kamer verkiezingen is er hernieuwde aandacht voor samenspraak bij beleid en beleidsexperimenten om te komen tot beter beleid. Het rendement daarvan is naar verwachting beperkt. Ten eerste omdat samenspraak vaak zodanig ingeperkt is, dat de invloed van kennis voor beleid beperkt blijft. Ten tweede omdat wetenschappelijke kennis prevaleert boven de voor beleidseffectiviteit noodzakelijke tacit knowledge. De rijksoverheid kan meer rendement halen uit investeringen in een betere beleidsvoorbereiding, door de structurele afweging tot de inzet van samenspraak en beleidsexperimenten bij nieuw of gewijzigd beleid; verantwoording van deze afweging, alsmede onafhankelijke toetsing van de te verwachten beleidseffectiviteit. Investeringen in handreikingen zijn weinig zinvol. De gemeente Rotterdam geeft een goed voorbeeld.
Let’s talk about sex: How people with intellectual disability in Australia engage with online social media and intimate relationships
Authors: Darragh Judith , Reynolds Louise , Ellison Caroline , Bellon Michelle 
Published: June 2017

People with intellectual disability often experience repression and control of their sexuality as they have historically been perceived as being childlike and asexual by members of society. Such acts can be seen to contravene their Human Rights under The Convention on the Rights of Person with Disabilities (CRPD), which endorses the rights of people with intellectual disability to fully express their sexuality.The purpose of this study was to explore if people with intellectual disability access internet based social media, and if so, if they use it to form relationships that express their sexuality. Using an interpretative phenomenological approach, semi-structured interviews were conducted with 30 adults with an intellectual disability (22 males, 8 females), aged between 20 to 66 years. Participants were purposely sampled though disability #organisations.Three themes emerged from the data: creating new friendships, maintaining existing friendships, exploring and expressing sexuality. People with intellectual disability used a variety of personal electronic devices to access internet based social media to be socially and sexually active. Facebook was accessed to make contact with existing platonic friends, peers and interest groups to meet socially. Sexually explicit material was viewed using the internet, either as an individual activity or by couples in monogamous relationships. This study adds to the paucity of research examining the use of internet based social media by people with intellectual disability for sexual expression. This research revealed the people with intellectual disability exercised cyber safe practices without any explicit formal education and conducted themselves in a respectful manner. Few participants acted in a manner that appeared to put them at risk of exploitation.
The effects of bursty bulk flows on global‐scale current systems

Published: June 2017

AbstractUsing a global magnetospheric MHD model coupled with a kinetic ring current model, we investigate the effects of magnetotail dynamics, particularly the earthward bursty bulk flows (BBFs) produced by the tail reconnection, on the global‐scale current systems. The simulation results indicate that after BBFs brake around X = −10 RE due to the dipolar “magnetic wall,” vortices are generated on the edge of the braking region and inside the inner magnetosphere. Each pair of vortex in the inner magnetosphere disturbs the westward ring current to arc radially inward as well as toward high latitudes. The resultant pressure gradient on the azimuthal direction induces region‐1 sense field‐aligned component from the ring current, which eventually is diverted into the ionosphere at high latitudes, giving rise to a pair of field‐aligned current (FAC) eddies in the ionosphere. On the edge of the flow braking region where vortices also emerge, a pair of region‐1 sense FACs arises, diverted from the cross‐tail duskward current, generating a substorm current wedge. This is again attributed to the increase of thermal pressure ahead of the bursty flows turning azimuthally. It is further found that when multiple BBFs, despite their localization, continually and rapidly impinge on the “wall,” carrying sufficient tail plasma sheet population toward the Earth, they can lead to the formation of a new ring current. These results indicate the important role that BBFs play in bridging the tail and the inner magnetosphere ring current and bring new insight into the storm‐substorm relation.
Carbon contents in reduced basalts at graphite saturation: Implications for the degassing of Mars, Mercury, and the Moon
Authors: Li Yuan , Dasgupta Rajdeep , Tsuno Kyusei 
Published: June 2017

AbstractCarbon contents in reduced Martian basalts at graphite saturation were experimentally studied at 1400–1550°C, 1–2 GPa, and logfO2 of IW − 0.4 to IW + 1.5 (IW denotes the Fe‐FeO buffer). The results show that carbon solubility in Martian basalts, determined by secondary ion mass spectrometry, is 20 to 1400 ppm, increasing with increasing fO2. Raman and Fourier transform infrared spectroscopic measurements on the quenched silicate glasses show that the dominant carbon species in Martian basalts is carbonate (CO32−). The experimental data generated here were combined with literature data on similar graphite‐saturated carbon solubility for mafic‐ultramafic compositions to develop an empirical model that can be used to predict carbon content of graphite‐saturated reduced basalts at vapor‐absent conditions:

urn:x-wiley:21699097:media:jgre20688:jgre20688-math-0002
in which T is temperature in K, P is pressure in GPa, XH2O is mole fraction of water in basalts, ΔIW is the oxygen fugacity relative to the IW buffer, and NBO/T = 2 total O/T − 4 (T = Si + Ti + Al + Cr + P). This model was applied to predict carbon content in graphite‐saturated mantle melts of the Mercury, Mars, and the Moon. The results show that graphite may be consumed during the production and extraction of some Martian basalts, and CO2 released by volcanism on Mars cannot be an efficient greenhouse gas in the early Mars. The lunar mantle carbon may be one of the main propellant driving the fire‐fountain eruption on the Moon; however, the Mercurian mantle carbon may not be an important propellant for the explosive eruption on Mercury.
Parameter‐dependent Riccati equation–based output feedback adaptive control
Authors: Kim Kilsoo , Calise Anthony J. , Yucelen Tansel 
Published: June 2017

SummaryA parameter‐dependent Riccati equation approach is proposed to design and analyze the stability properties of an output feedback adaptive control law design. The adaptive controller is intended to augment an existing fixed‐gain observer‐based output feedback control law. Although the formulation is in the setting of model reference adaptive control, the realization of the adaptive controller does not require implementing the reference model. In this regard, the increased complexity of implementing the adaptive controller, above that of a fixed‐gain control law, is less than that of other methods. The error signals are shown to be uniformly ultimately bounded, and an estimate for the ultimate bound is provided. The issue of sensor noise is addressed by introducing an error filter. The control design process and the theoretical results are illustrated using a model for wing rock dynamics.

Published: June 2017

AbstractCarbon ene–yne nanoribbons (CEYNRs), a novel 1D material, are synthesized from tetraethynylethene by using an anodic aluminum oxide template under mild conditions. Materials characterization illustrates that carbon ene–yne is entirely composed of sp‐hybrid and sp2‐hybrid carbon. CEYNRs exhibit excellent semiconductor properties; their conductivity is up to 3.2 × 10−2 S m−1, which facilitates their application in electronic devices. Also, CEYNRs have great potential as a competitive candidate for field emitters. CEYNRs may be a new versatile material for many green applications, such as electronics, optoelectronics, energy storage, packaging, and catalysis.

Published: June 2017

AbstractThe structural transition in micrometer‐sized liquid crystal bubbles (LCBs) derived from rod‐like cellulose nanocrystals (CNCs) was studied. The CNC‐based LCBs were suspended in nematic or chiral nematic liquid‐crystalline CNCs, which generated topological defects and distinct birefringent textures around them. The ordering and structure of the LCBs shifted from a nematic to chiral nematic arrangement as water evaporation progressed. These packed LCBs exhibited a specific photonic cross‐communication property that is due to a combination of Bragg reflection and bubble curvature and size.

AbstractFe‐N‐C catalysts with high O2 reduction performance are crucial for displacing Pt in low‐temperature fuel cells. However, insufficient understanding of which reaction steps are catalyzed by what sites limits their progress. The nature of sites were investigated that are active toward H2O2 reduction, a key intermediate during indirect O2 reduction and a source of deactivation in fuel cells. Catalysts comprising different relative contents of FeNxCy moieties and Fe particles encapsulated in N‐doped carbon layers (0–100 %) show that both types of sites are active, although moderately, toward H2O2 reduction. In contrast, N‐doped carbons free of Fe and Fe particles exposed to the electrolyte are inactive. When catalyzing the ORR, FeNxCy moieties are more selective than Fe particles encapsulated in N‐doped carbon. These novel insights offer rational approaches for more selective and therefore more durable Fe‐N‐C catalysts.

AbstractZinc‐induced oligomerization of amyloid‐β peptide (Aβ) produces potentially pathogenic agents of Alzheimer's disease. Mutations and modifications in the metal binding domain 1–16 of Aβ peptide crucially affect its zinc‐induced oligomerization by changing intermolecular zinc mediated interface. The 3D structure of this interface appearing in a range of Aβ species is a prospective drug target for disease modifying therapy. Using NMR spectroscopy, EXAFS spectroscopy, mass spectrometry, and isothermal titration calorimetry the interaction of zinc ions with Aβ fragments 1–7 and 1–10 carrying familial Taiwanese mutation D7H was studied. Zinc ions induce formation of a stable homodimer formed by the two peptide chains fastened by two zinc ions and stacking interactions of imidazole rings. A binuclear zinc interaction fold in the dimer structure was discovered. It can be used for designing zinc‐regulated proteins and zinc‐mediated self‐assembling peptides.

BACKGROUNDSchool absence is associated with lower performance on standardized tests. Children born with orofacial clefts (OFC) are likely to have more absence than children without OFC; however, school absence for children with OFC has not been quantified. We aimed to describe school absence and its relationship with school performance for children with and without OFC.METHODSPopulation‐based record‐linked cohort study of children (402 with OFC, 1789 without OFC) enrolled in schools in Western Australia, 2008 to 2012. We compared median school absence rates using Wilcoxon rank tests, and investigated the impact of school absence on standardized scores from reading, numeracy, and writing tests, using multivariable models fitted by generalized estimating equations.RESULTSIn Semester 1, at each primary school year level, children without OFC and children with cleft lip only or cleft palate only had similar median absence rates (approximately 1 week). Children with cleft lip and palate had significantly higher absence rates in Years 4 to 6 (between 1 and 2 weeks). During secondary school, median absence rates were higher (2 weeks) for all children, but not statistically different between children with and without OFC. Higher absence was significantly associated with lower standardized reading, numeracy, and writing scores. However, having a cleft of any type had little influence on the association between absence and test scores.CONCLUSIONSchool absence affected school performance for all children. Absence did not differentially disadvantage children born with OFC, suggesting current practices to identify and support children with OFC are minimizing effects of their absence on school performance.

AbstractHepatocellular carcinoma (HCC) is one of the most prevalent malignancies and a major cause of cancer involved death worldwide. Prognosis remains poor because of high recurrence rates and lack of effective relapse prevention strategies. Notch pathway plays an important role in tumor progression and metastasis, and it is associated with the prognosis of cancer. A total of 465 hepatitis B virus (HBV)‐related HCC patients who underwent surgery were enrolled. Single nucleotide polymorphisms (SNP) of Notch pathway receptors were genotyped using Sanger DNA sequencing. Kaplan–Meier curves and the Cox proportional hazards regression model were adopted to analyze the association of polymorphisms and mRNA expression with clinical and pathological features, respectively. Four SNPs (rs1043996 in Notch3 and rs422951, rs520692, rs3830041 in Notch4) were significantly associated with overall survival (OS) (P = 0.023, P = 0.042, P = 0.028, and P = 0.001 respectively). Patients carrying the AA genotype in rs1043996 and TT/TC genotypes in rs422951 and rs520692 significantly decreased risks of death, compared to those carrying the AG/GG genotype in rs1043996 and CC genotype in rs422951 and rs520692, respectively. Patients carrying the TT genotype in rs3830041 showed poorer OS, compared with those carrying the TC/CC genotype. A haplotype block (rs422951 was in strong LD with rs520692, r2 = 0.843) was identified in Notch4. Notch3 mRNA expression significantly increased in tumor tissue, compared with nontumor normal tissue (P < 0.0001). Moreover, higher expression of Notch3 was associated with poorer OS (HR = 2.11, 95% CI = 1.32–3.37, P = 0.002) and shorter recurrence time of HBV‐related HCC (HR = 1.96, 95% CI = 1.31–2.93, P = 0.001). Our findings collectively indicate that Notch receptors variants (rs1043996 in Notch3 and rs422951, rs520692, rs3830041 in Notch4) are independent predictive targets for OS in HBV‐related HCC patients. Notch3 expression is a potential prognostic biomarker of OS and recurrence‐free survival (RFS) prediction in HBV‐related HCC patients following surgical treatment.
