On Some Hadamard-Type Inequalıtıes for (r,m) -Convex Functıons

In this paper, we define a new class of convex functions which is called (r,m) - convex functions. We also prove some Hadamard\u27s type inequalities based on this new definition

Systematic or multiple reproduction or distribution to multiple locations via electronic or other means is prohibited and is subject to penalties under law[EN] Single-wall carbon nanotube deposition on the cladding of optical fibers has been carried out to fabricate an all-fiber nonlinear device. Two different nanotube deposition techniques were studied. The first consisted of repeatedly immersing the optical fiber into a nanotube supension, increasing the thickness of the coating in each step. The second deposition involved wrapping a thin film of nanotubes around the optical fiber. For both cases, interaction of transmitted light through the fiber core with the external coating was assisted by the cladding mode resonances of a tilted fiber Bragg grating. Ultrafast nonlinear effects of the nanotube-coated fiber were measured by means of a pump-probe pulses experiment. © 2011 Optical Society of America.This work was financially supported by the European Commission under the FP7 EURO-FOS Network of Excellence (ICT-2007-2-224402), the Ministerio de Educación y Ciencia SINADEC project (TEC2008-06333), and the Natural Sciences and Engineering Research Council of Canada (NSERC).

Novel results on Hermite-Hadamard kind inequalities for η\eta-convex functions by means of (k,r)(k,r)-fractional integral operators

We establish new integral inequalities of Hermite-Hadamard type for the recent class of $\eta$-convex functions. This is done via generalized $(k,r)$-Riemann-Liouville fractional integral operators. Our results generalize some known theorems in the literature. By choosing different values for the parameters $k$ and $r$, one obtains interesting new results.Comment: This is a preprint of a paper whose final and definite form is a Springer chapter in the Book 'Advances in Mathematical Inequalities and Applications', published under the Birkhauser series 'Trends in Mathematics', ISSN: 2297-0215 [see http://www.springer.com/series/4961].

Third molar development in a London population of White British and Black British or other Black ethnicity.

Funder: NIHR Cambridge Biomedical Research CentrePopulation differences in dental development between Black and White ethnic groups have been debated but not previously studied in the UK. Using inappropriate data for dental age estimation (DAE) could lead to erroneous results and injustice. Data were collected from dental panoramic radiographs of 5590 subjects aged 6-24 years in a teaching hospital archive. Demirjian stages were determined for left-sided teeth and third molars and data collected regarding hypodontia and third molar agenesis. Third molar development in self-assigned Black British, including other self-assigned Black ethnicity, was compared with that of self-assigned White British subjects. Data were compared for males and females in the two ethnic groups using T-tests for Demirjian Stages A-G of third molar development and Mann-Whitney tests for Stage H once a cut-off age at the maximum age for Stage G had been imposed. Third molar development occurred earlier in subjects of Black ancestry compared to those of White ancestry. While both ethnic groups showed large age ranges for every third molar stage, in female subjects these generally occurred at least 1.5 years earlier, and in males at least one year earlier. Hypodontia and third molar agenesis were more prevalent in White British, but the ethnic difference in third molar development persisted in subjects with complete dentitions. This is a large study that confirms ethnic differences in a London population, emphasises the difficulties of establishing the 18-year-old threshold using DAE, and confirms the risk of overestimating the age of individuals of Black ethnicity using White ethnic reference data

When a workforce strategy won't work : critique on current policy direction in England, UK

“The final, definitive version of this article has been published in the Journal, Journal of Intellectual Disabilities: JOID, Vol.14 Issue 4, 2010, Copyright SAGE Publications Ltd on SAGE Journals Online: http://online.sagepub.com/ "This editorial is based on findings from a regional review of educational commissioning, and workforce issues for one Strategic Health Authority in England. Known as the ‘Valued People Project’ (VPP) it commenced in May 2008 and was undertaken in response to expressed concerns by regional key stakeholders regarding education commissioning specifically of pre-registration learning disability nursing, and the contribution of the specialist learning disability health workforce more generally (Gates, 2009). This work was also undertaken as a consequence of the scale and cumulative effect of changes to education, workforce, professional regulation and central health and social care policy that has affected people with learning disabilities, and the services and personnel that support them.Peer reviewedFinal Accepted Versio

Enfermedad renal crónica: la carga sanitaria invisible para los organismos que

REDINREN RD16/0009.The uptake of the current concept of chronic kidney disease (CKD) by the public, physicians and health authorities is low. Physicians still mix up CKD with chronic kidney insufficiency or failure. In a recent manuscript, only 23% of participants in a cohort of persons with CKD had been diagnosed by their physicians as having CKD while 29% has a diagnosis of cancer and 82% had a diagnosis of hypertension. For the wider public and health authorities, CKD evokes kidney replacement therapy (KRT). In Spain, the prevalence of KRT is 0.13%. A prevalent view is that for those in whom kidneys fail, the problem is "solved" by dialysis or kidney transplantation. However, the main burden of CKD is accelerated aging and all-cause and cardiovascular premature death. CKD is the most prevalent risk factor for lethal COVID-19 and the factor that most increases the risk of death in COVID-19, after old age. Moreover, men and women undergoing KRT still have an annual mortality which is 10-100-fold higher than similar age peers, and life expectancy is shortened by around 40 years for young persons on dialysis and by 15 years for young persons with a functioning kidney graft. CKD is expected to become the fifth global cause of death by 2040 and the second cause of death in Spain before the end of the century, a time when 1 in 4 Spaniards will have CKD. However, by 2022, CKD will become the only top-15 global predicted cause of death that is not supported by a dedicated well-funded CIBER network research structure in Spain. Leading Spanish kidney researchers grouped in the kidney collaborative research network REDINREN have now applied for the RICORS call of collaborative research in Spain with the support of the Spanish Society of Nephrology, ALCER and ONT: RICORS2040 aims to prevent the dire predictions for the global 2040 burden of CKD from becoming true. However, only the highest level of research funding through the CIBER will allow to adequately address the issue before it is too late.El impacto del concepto actual de enfermedad renal crónica (ERC) en la población, médicos y autoridades sanitarias ha sido bajo. Los médicos aún confunden la ERC con la insuficiencia renal crónica. En un manuscrito reciente, en una cohorte de personas con ERC, solo el 23% de los participantes fueron diagnosticados de ERC por sus médicos mientras que el 29% estaban diagnosticados de cáncer y el 82% de hipertensión. Para el público en general y las autoridades sanitarias, la ERC evoca la terapia de reemplazo renal (TRR). En España, la prevalencia de TRR es del 0,13%. La opinión predominante es que para aquellos en los que fallan los riñones, el problema se “resuelve” mediante diálisis o trasplante de riñón. Sin embargo, la principal carga sanitaria de la ERC es el envejecimiento acelerado y la muerte prematura de causa cardiovascular o de cualquier causa. La ERC es el factor mas prevalente de riesgo de mortalidad por COVID-19 después de la edad avanzada. Además, los hombres y mujeres que se someten a TRR todavía tienen una mortalidad anual que es de 10 a 100 veces superior a sus pares de edades similares, y la esperanza de vida se reduce en alrededor de 40 años para jóvenes en diálisis y en 15 años para jóvenes con un injerto renal funcionante. Se espera que la ERC se convierta en la quinta causa mundial de muerte para 2040 y la segunda causa de muerte en España antes de fin de siglo, época en la que 1 de cada 4 españoles tendrá ERC. Sin embargo, para 2022, la ERC se convertirá en la única causa de muerte entre las 15 principales a nivel mundial que no cuenta con el respaldo de una estructura de investigación CIBER en España. Los Principales grupos de investigación renal en España agrupados en la red de investi- gación colaborativa renal REDINREN han solicitado la convocatoria RICORS de investigación colaborativa en España con el apoyo de la Sociedad Española de Nefrología, ALCER y ONT: RICORS 040 tiene como objetivo evitar que se hagan realidad las terribles predicciones sobre la carga mundial de ERC para 2040. Sin embargo, solo el más alto nivel de financiación de la investigación a través del CIBER permitirá abordar adecuadamente el problema antes de que sea demasiado tarde.REDINREN RD16/000
