Angiographic catheters and Guiding catheters play an important role in percutaneous coronary intervention. The structure and performance of the Angiographic catheter determine whether the contrast agent can be successfully injected into the target vessel, thus providing a preliminary basis for the diagnosis of the disease. Guiding catheter provides access for related devices and determines whether percutaneous coronary intervention can be carried out smoothly. The structure of the angiographic catheter and the guiding catheter are described in detail. The angiographic catheter consists of hub, relief, body, bridge section and soft tip. The structure of the guiding catheter includes hub, relief, pushing section, kink-resistance section, coaxial section and a soft tip. The materials and processing technology involved in each component of angiographic catheter and guiding catheter are described and analyzed in detail.

Published: October 2022

A magnesium oxide and titanium (II) oxide nanocomposite, MgO/TiO2 was synthesized to improve its surface area thus its adsorption capability may be risen. The synthesis was applying sol-gel method, combining MgO and TiO2 nanoparticles with NaOH becomes a nanocomposite with higher surface area. The pH effect on adsorption were analyzed. The expectation of using MgO/TiO2 compared with TiO2 and MgO alone is it may react faster on an adsorption trial with remazol turquoise blue dye, and the TiO2 may give its photocatalysis ability to the synthesized material. Less acid the condition of the solution, the capability of the MgO/TiO2 catalyst on adsorbing the remazol turquoise blue dye will increasing. After 90 minutes, the photocatalysis rate surpass the adsorption rate and reach equilibrium.

Published: October 2022

An experimental study has been carried out to investigate and compare the cutting tool performances represented by insert wear, surface roughness and cutting forces of an uncoated carbide (H13A) and three coated carbides GC2015 ( TiCN / Al2O3 / TiN ), GC1015 (TiN) and GC4215 ( TiCN / Al2O3 ) during the dry turning of AISI4140 steel. Turning was carried out during 5 minutes on cylindrical specimens (80 mm diameter and 400 mm cutting length) along with a depth of 0.5 mm, a feed rate of 0.08 mm/rev, and with a cutting speed of 350 m/min. The wear results show the effectiveness of both GC2015 and GC4215 cutting inserts where the flank wear rate of the monolayer insert (GC1015) reaches approximately 2 times that of the bilayer insert (GC4215) and 4-times that of the multilayer insert (GC2015), while insert H13A demonstrated the highest wear. Moreover, SEM analysis shows that abrasion, adhesion and chipping are the dominant wear mechanisms. The surface quality obtained with the coated GC2015 insert is found to be 1.38, 1.63 and 4.63 times better than those obtained with GC4215, GC1015 and H13A inserts respectively. Finally, the coated GC2015 (CVD) cutting insert is identified as the leading material in terms of cutting force as the results found show that the ratios are ( Ft-GC4215 / Ft-GC2015 ) = 1.05, ( Ft-GC1015 / Ft-GC2015 ) = 1.13 and ( Ft-H13A / Ft-GC2015 ) = 1.77.
La Convención del Patrimonio Mundial, cincuenta años después de su aprobación
Authors: Conti Alfredo 
Published: October 2022

La conmemoración del cincuentenario de la Convención del Patrimonio Mundial, adoptada por la Conferencia General de la UNESCO el 16 de noviembre de 1972, se da en un momento en que la humanidad se enfrenta a situaciones complejas, tales como los impactos del cambio climático, la inesperada pandemia COVID-19, que puso en evidencia desigualdades aun en el interior de algunos países, y una serie de conflictos bélicos y humanitarios, de los cuales el más reciente es la invasión por parte de la Federación Rusa al territorio soberano de la República de Ucrania. Puede resultar difícil, por lo tanto, proceder a una evaluación del significado y alcances de la Convención sin abstraerse del contexto y de la pregunta acerca de si los ideales propuestos para la UNESCO en su fundación en 1945 han podido realmente concretarse.
Un recorrido exhaustivo por el medio siglo de la Convención excedería ampliamente los límites de un artículo. Se procede, por lo tanto, a mencionar solo algunos momentos o aspectos que se han considerado significativos para narrar y analizar el devenir del sistema Patrimonio Mundial, de modo de extraer algunas conclusiones que permitan un somero balance de lo logrado y de los desafíos que se esperan en el futuro próximo. El sistema creado por la Convención ha permitido, sin dudas, poner en evidencia sitios importantes para toda la humanidad y contribuir a su adecuada gestión. Pero, por otra parte, pone en evidencia desigualdades y diferencias de oportunidades entre regiones y países del mundo.

Published: October 2022

Em crianças, as doenças da substância branca são divididas tradicionalmente em duas principais categorias: leucodistrofia e leucoencefalopatias. Sendo as primeiras, o resultado da deficiência enzimática hereditária que causa uma formação anormal, renovação da mielina ou destruição. Em contrapartida, as leucoencefalopatias envolvem a destruição da mielina intrinsecamente normal, tendo como mecanismo da desmielinização a divisão primariamente em lisossomal, e peroxissomal. Neste contexto, a Síndrome Pelizaeus-Merzbacher (PMD) é uma leucodistrofia ligada ao cromossomo X, caracterizada pelo atraso no desenvolvimento neuropsicomotor em crianças. Trata-se de uma doença rara, com predominância para sexo masculino comprometendo o desenvolvimento e/ou a manutenção da mielina no Sistema Nervoso Central (SNC). Logo, o presente estudo objetivou reunir artigos científicos através de uma revisão narrativa sobre a Doença Pelizaeus Merzbacher abordando sua classificação, fisiopatologia, sinais e sintomas e os desafios para se chegar em seu diagnóstico. Desta forma, este estudo traz novas atualizações sobre a doença e auxílio no direcionamento para um diagnóstico diferencial, assim como, buscar uma melhor intervenção para pacientes com Síndrome Pelizaeus-Merzbacher.
A reciprok tanítási módszer elemeinek jelentősége az olvasás–szövegértés tanítás eredményességének fejlesztésében
Authors: Huszár-Samu Nóra , Steklács János 
Published: October 2022

Az olvasási, szövegértési képesség jelentősége nagymértékben átértékelődött az elmúlt évtizedekben, ezeknek a képességeknek a megfelelő szintje minden további tanulás előfeltétele, ezzel együtt általánosságban a boldogulás fontos tényezője az egyén életében az információs társadalomban egyaránt (Grabe–Stoller 2011; Schnotz–Molnár 2012). Bár az olvasás, szövegértés megfelelő szintjének elérése társadalmi igény, napjainkban ennek ellenére a literacy crisis, az olvasás válsága és funkcióvesztése a jellemző (Szenczi 2010; Józsa–Józsa 2014). Az iskolának mint intézménynek reflektálnia kell a társadalom szükségleteire, de a szövegértés képességét azért nem tudja mindennapi társadalmi igényeknek és elvárásoknak megfelelően kialakítani kisiskolás korban, mert a nemzetközi kutatások a szövegértésről alkotott új tudáskoncepció és a módszertani eszköztár és kultúra fejlődése számottevő különbségeket mutat. A szövegfeldolgozás módszertanának jelentős tartalékai maradnak kiaknázatlanul az elmélet és gyakorlat eltéréseinek okán. Tanulmányunkban arra kívánunk rámutatni, hogy az alsó tagozaton történő olvasásmegértés hatékony és gyakorlatorientált fejlesztése a metakognitív folyamatok és struktúrák fejlesztésében rejlik. Az olvasástanítás dekódolási, automatizálási szakasza utáni, a szövegértés tanítását explicit módon célzó szakasza, egyben egyik leghatékonyabb módszere az olvasási stratégiákra épül. Ez az egyik elméleti alapvetése a reciprok módszernek is, melynek elemei a gyakorlatban a tanórába illeszthetőek, és lefedik a metakognícióról alkotott elméleti keretet.
