A supported titanium postmetallocene catalyst: Effect of selected conditions on ethylene polymerization

2011

Ethylene polymerization with a titanium complex [N,N-ethylenebis(3-methoxysalicylideneiminato)titanium dichloride] immobilized on the magnesium support with the formula MgCl2(THF)0.32(Et2AlCl)0.36 was studied. In particular, the effects of polymerization temperature, monomer pressure, and polymerization time on the activity of the catalyst and on the polyethylene properties (molecular weight and its distribution, melting point, crystallinity, and bulk density) were evaluated. The findings of investigations prove that the studied supported titanium catalyst is highly active in ethylene polymerization, and its activity increases with increasing temperature and monomer pressure. Moreover, stab…

Competition between chain scission and branching formation in the processing of high-density polyethylene: effect of processing parameters and of sta…

2009

Two samples of high-density polyethylene with different molecular weight were processed in a batch mixer and the rheological and structural properties were investigated. In particular, the effect of different processing parameters and the eventual presence of different stabilizers were evaluated. Actually, two reactions may occur during processing: branching/crosslinking or chain scission. The results indicate that when the processing conditions promote a scarce mobility of the macromolecular chains (lower temperatures, lower mixing speed, and higher molecular weight), branching is more favored than chain scission. On increasing the mobility of the chain (higher temperature, higher mixing s…

Construction of whiteness and blackness in Herman Melville's "Benito Cereno"

2020

Zamiast otwartego potępienia niewolnictwa, świat przedstawiony Benito Cereno rozprasza sprzeciw wobec tyranii poprzez zawiłą konstrukcję relacji podmiotowo-przedmiotowych, kontekst sytuacyjny, stłumione, nie do końca wyartykułowane wypowiedzi Benito Cereno, obrazy oraz złożoną strukturę dzieła. Za pomocą przemilczeń, zastosowania różnorodnych punktów widzenia, napomknięć, czy wyrazistej niedookreśloności, dzieło Melvilla nie tylko wpisuje się w romantyczne kwestionowanie historiografi i, ale również wychodzi naprzeciw postmodernistycznej nieoczywistości. Jest to utwór, w którym czytelnik zostaje zaproszony do bycia współautorem wypełniającym luki i przemilczenia własną interpretacją.

"Risuoni e risuoni o chimera": Amelia Rosselli dialogue avec les "Canti Orfici"

2015

International audience; Après avoir fait un bilan des éléments biographiques et poétiques qui permettent de rapprocher l’œuvre d’Amelia Rosselli de celle de Dino Campana, l’article examine la reprise parodique des vers du poète de Marradi contenue dans le poème « Per la tua pelle olivastra per la tua mascella cadente» tiré de "Variazioni belliche" (1964). Il montre ensuite que le dialogue avec les "Chants Orphiques" ne se confine pas aux reprises parodiques mais qu’il nourrit de façon souterraine toute l’œuvre d’Amelia Rosselli, dans les domaines lexical, syntaxique et rythmique. L’article considère enfin certains procédés stylistiques typiques de la poésie campanienne tels que l’itération,…

Comparative analysis of socioeconomic, behavioral and biological factors between healthy patients and patients with newly diagnosed diabetes in the L…

2020

Introduction. The most effective way to prevent a dramatic increase in the number of diabetic patients lies in early detection of its risk factors and the diagnosis of carbohydrate metabolism disorders. Aim of the study. The study aims at determining socio-economic variables, lifestyle behaviours and biological factors differentiating patients with newly diagnosed diabetes from the diabetes-free individuals according to the American criteria issued by the Commission on Social Determinants of Health as well as FINDRISC form which helps identify patients who are at risk of developing diabetes type 2 on the basis of multi-factorial determinants of its development.

Diabēta medikamentu blakusparādības

2016

Ievads: Vēljoprojām ir sastopamas nozīmīgas blaknes diabēta zālēm, kas ir īpaši nozīmīgi pieaugot saslimstībai ar diabētu pasualē, kā arī Latvijā. Atpazīt diabēta medikamentu izraisītās blaknes ir svarīgi, lai novērstu smagās komplikācijas, ko tās var radīt. Pētijuma mērķis: pētījuma mērķis bija konstatēt blakņu esamību hospitalizētajiem diabēta pacientiem. Materiāli un Metodes: pētījumi, iekļāva pacientus, kuri diagnozticēti ar diabetes mellitus. Pacienti tika iztaujāti par medikamentiem, kurus viņi lieto atveseļošanās periodā un par viņu zināmām vai nezināmajām novērotajām blaknēm. Rezultāti: Pētījumā tika iekļauti 50 pacienti, ar abu, 1. un 2. tipa diabētiem. Pētāmo pacientu grupa sastāv…

Controversies in ameloblastoma management: Evaluation of decision making, based on a retrospective analysis

2020

Background The ameloblastoma management is still challenging to the high recurrence rates and significant morbidity associated with radical treatment. The purpose of this 10-year retrospective study was to analyze the influence of ameloblastoma type and treatment strategy on the long-term outcomes and recurrence rates. Material and Methods The retrospective analyses of 64 histologically-confirmed ameloblastoma cases was performed. The possible risk factors for recurrence and the development of complications were estimated statistically. Results The treatment strategy applied for this group of patients was the following: thirty-four patients (53.1%) were treated conservatively with enucleati…

Pacienta un ambulatorās aprūpes māsas sadarbība melanomas riska mazināšanā

2020

Melanomas gadījumu skaits ik gadu pieaug un ambulatorās aprūpes māsām jābūt kompetentām, izglītojot pacientus. Sakarā ar melanomas bīstamību un gadījumu skaita pieaugšanu tika izvēlēta tēma un izveidots pētījums, lai noskaidrotu kādas ir izglītošanas īpatnības ambulatorās aprūpes māsām. Galvenie pētniecības uzdevumi ir izpētīt literatūru atbilstoši izvirzītajai tēmai par melanomu un profilaksi ambulatorās aprūpes māsas praksē. Analizēt Virdžīnijas Hendersones pamatvajadzību teoriju, izstrādāt pētījuma instrumentu, veikt pētījumu un apkopot iegūtos rezultātus, balstoties uz iegūtajiem rezultātiem, izdarīt secinājumu.

La licantropía y el efialtes en la literatura médica griega: los testimonios de Areteo, Galeno, Posidonio y Aecio de Amida, Oribasio y Actuario (más …

2018

Textos médicos de las épocas imperial y bizantina nos proporcionan alguna información sobre las patologías de la licantropía y el llamado efialtes, que son tratadas correlativamente y que presentan algunas características comunes a ambas, si bien es la primera la que recibe mayor atención. El presente trabajo comprende brevemente los pasajes de mayor interés, acompañados de su traducción y de un somero comentario que atiende a la problemática filológica, histórica y médica. Se concluye el acierto de la medicina griega al relacionar ambas afecciones con la estabilidad psiquiátrica del paciente, exactamente como lo hace la medicina moderna, sin por ello dejar de lado el establecimiento de una…
