The aim of this study is to examine evaluate the impact of placement test results on EFL learners' motivation. Researcher selects students of Safir Institute as the participants of the study. Researcher evaluates new students who participate in placement test during two months. This branch is only for female students. Interview is the instrument that is employed in this study. Researcher selects some students randomly, in order to interview with them about the relationship among language aptitude, willingness to communicate and pronunciation.

Investigating the Feasibility of Creating Quality Management Systems

Investigating the Feasibility of Creating Quality Management Systems

Today, no country lives in complete isolation from other countries. The economic resources, technology and standard of living of the people of a country are relatively dependent on the economy of other countries, which are related by a complex flow of goods, services, capital and technology. Through international exchanges, countries increase their production level and earn more profit. Through imports, they get the goods that they are unable to produce, and through exports, they send the manufactured goods that are surplus to their consumption to other countries. Although a country may have different factors of production and be able to produce all kinds of goods, it will not be able to produce them at the same price. The primary cause of international exchanges is the difference in the prices of goods and services of countries. The difference in prices is either due to the difference in the conditions of supply or facilities, production or the difference in the conditions of demand or consumption pattern or a combination of them.

Malhas nanofibrosas referem-se s estruturas feitas de fibras polim ricas ultrafinas. Devido ao tamanho nanom trico com uma alta rela o resist ncia/peso, eles s o muito adequados como um nanossistema para entrega de mol culas de medicamentos. Mol culas de drogas que se misturam em nanofibras podem ser liberadas do ambiente circundante por meio de v rios mecanismos de diferentes maneiras (libera o explosiva, libera o sustent vel e libera o sintoniz vel). As nanofibras podem ser usadas como estrat gias de controle da taxa de libera o como estruturas de entrega adequadas para mol culas de medicamentos. O objetivo desta revis o destacar a capacidade das nanofibras como novas subst ncias liberadoras de profenos (medicamentos derivados do cido propi nico, incluindo Carprofeno; Naproxeno; Fenoprofeno; Flurbiprofeno; Ibuprofeno; Cetoprofeno e cido Tiaprof nico). Os profens s o uma classe de antiinflamat rios n o ester ides (AINEs) n o seletivos. Essas mol culas de drogas s o derivadas do cido 2-fenilpropan ico. Todos cont m um centro quiral resultando na forma o de dois enanti meros (R e S) de cada profeno. Nesta revis o, ser o relatadas informa es completas sobre os novos progressos nos comportamentos de libera o de mol culas de profeno da nova entrega nanofibrosa.

Freisetzungsverhalten von Profen-Medikamenten aus Nanofasern

Freisetzungsverhalten von Profen-Medikamenten aus Nanofasern

Unter Nanofasernetzen versteht man Strukturen aus ultrafeinen Polymerfasern. Aufgrund ihrer Gr e im Nanometerbereich mit einem hohen Verh ltnis von Festigkeit zu Gewicht eignen sie sich sehr gut als Nanosystem zur Abgabe von Arzneimittelmolek len. Arzneimittelmolek le, die sich in Nanofasern vermischen, k nnen durch verschiedene Mechanismen auf unterschiedliche Weise aus der Umgebung freigesetzt werden (Burst-Freisetzung, nachhaltige Freisetzung und einstellbare Freisetzung). Nanofasern k nnen im Rahmen von Strategien zur Steuerung der Freisetzungsrate als geeignete Transportstrukturen f r Arzneimittelmolek le eingesetzt werden. Ziel dieser bersicht ist es, die F higkeit von Nanofasern als neuartige Freisetzungssubstanzen f r Profene (Propions urederivate, darunter Carprofen, Naproxen, Fenoprofen, Flurbiprofen, Ibuprofen, Ketoprofen und Tiaprofens ure) hervorzuheben. Die Profene sind eine Klasse nichtselektiver, nichtsteroidaler entz ndungshemmender Arzneimittel (NSAIDs). Diese Arzneimittelmolek le sind Derivate der 2-Phenylpropans ure. Alle enthalten ein chirales Zentrum, was zur Bildung von zwei Enantiomeren (R und S) jedes Profens f hrt. In diesem Aufsatz werden umfassende Informationen ber die neuen Fortschritte beim Freisetzungsverhalten von Profenmolek len aus der neuartigen Nanofaserabgabe berichtet.

Les maillages nanofibreux font r f rence aux structures constitu es de fibres polym res ultrafines. En raison de leur taille nanom trique avec un rapport r sistance/poids excessif, ils conviennent tr s bien comme nanosyst me pour administrer des mol cules m dicamenteuses. Les mol cules m dicamenteuses m lang es aux nanofibres peuvent tre lib r es du milieu environnant au moyen de divers m canismes et de diff rentes mani res (lib ration en rafale, lib ration durable et lib ration r glable). Les nanofibres peuvent tre utilis es dans le cadre de strat gies de contr le du taux de lib ration en tant que structures d'administration appropri es pour les mol cules m dicamenteuses. L'objectif de cette revue est de mettre en vidence la capacit des nanofibres en tant que nouvelles substances lib ratrices de prof nes (m dicaments d riv s de l'acide propionique, notamment le carprof ne, le naprox ne, le f noprof ne, le flurbiprof ne, l'ibuprof ne, le k toprof ne et l'acide tiaprof nique). Les prof nes sont une classe d'anti-inflammatoires non st ro diens (AINS) non s lectifs. Ces mol cules m dicamenteuses sont des d riv s de l'acide 2-ph nylpropano que. Tous contiennent un centre chiral entra nant la formation de deux nantiom res (R et S) de chaque prof ne. Dans cette revue, des informations compl tes seront rapport es sur les nouveaux progr s concernant les comportements de lib ration des mol cules de prof ne partir de la nouvelle d livrance nanofibreuse.

Le reti nanofibrose si riferiscono alle strutture costituite da fibre polimeriche ultrafini. A causa delle dimensioni nanometriche con un rapporto resistenza/peso eccessivo, sono effettivamente adatti come nanosistema per la distribuzione di molecole di farmaci. Le molecole farmacologiche mescolate nelle nanofibre possono essere rilasciate dall'ambiente circostante mediante vari meccanismi in diverse modalit (rilascio burst, rilascio sostenibile e rilascio sintonizzabile). Le nanofibre possono essere utilizzate mediante strategie di controllo della velocit di rilascio come strutture di rilascio adeguate per le molecole di farmaci. L'obiettivo di questa revisione quello di evidenziare la capacit delle nanofibre come nuove sostanze di rilascio per i profeni (farmaci derivati ​​​​dell'acido propionico tra cui Carprofen; Naproxen; Fenoprofen; Flurbiprofen; Ibuprofen; Ketoprofen e acido tiaprofenico). I profens sono una classe di farmaci antinfiammatori non steroidei (FANS) non selettivi. Queste molecole farmacologiche sono derivati ​​dell'acido 2-fenilpropanoico. Tutti contengono un centro chirale che porta alla formazione di due enantiomeri (R e S) di ciascun profen. In questa recensione, verranno riportate informazioni complete sui nuovi progressi per i comportamenti di rilascio delle molecole di profene dal nuovo rilascio nanofibroso.
