Design and Characterization of Effective Ag, Pt and AgPt Nanoparticles to H2O2 Electrosensing from Scrapped Printed Electrodes
2019
The use of disposable screen-printed electrodes (SPEs) has extraordinarily grown in the last years. In this paper, conductive inks from scrapped SPEs were removed by acid leaching, providing high value feedstocks suitable for the electrochemical deposition of Ag, Pt and Ag core-Pt shell-like bimetallic (AgPt) nanoparticles, onto screen-printed carbon electrodes (ML@SPCEs, M = Ag, Pt or AgPt, L = metal nanoparticles from leaching solutions). ML@SPCEs were characterized by scanning electron microscopy, cyclic voltammetry and electrochemical impedance spectroscopy. The results were compared to those obtained when metal nanoparticles were synthesised using standard solutions of metal salts (MS@…
Microneedle-Based Delivery: An Overview of Current Applications and Trends
2020
Microneedle arrays (MNA) are considered as one of the most promising resources to achieve systemic effects by transdermal delivery of drugs. They are designed as a minimally invasive, painless system which can bypass the stratum corneum, overcoming the potential drawbacks of subcutaneous injections and other transdermal delivery systems such as chemical enhancers, nano and microparticles, or physical treatments. As a trendy field in pharmaceutical and biomedical research, its applications are constantly evolving, even though they are based on very well-established techniques. The number of molecules administered by MNA are also increasing, with insulin and vaccines administration being the …
"Kirjoittaminen on tie minuun, minusta sinuun" : ryhmämuotoinen kirjoittaminen ja metaforien merkitys psykoosia sairastavien kirjallisuusterapiassa
2015
This is a study on the significance of group poetry therapy and the use of metaphors by people diagnosed with psychosis. The data includes seven client interviews, poems and other texts written in the poetry therapy sessions, and my research diary; it was collected from a group I personally directed for one year. The research aimed to answer these questions: 1) what are the most meaningful and therapeutic aspects in group poetry therapy from the point of view of the client? 2) What is the per- sonal significance of therapeutic metaphor and poetic language for people who experience psychosis? 3) What kind of poetry therapy model is suitable for people with schizophrenia and other psychose…
A fluorescence study of the loading and time stability of doxorubicin in sodium cholate/PEO-PPO-PEO triblock copolymer mixed micelles
2019
Abstract Hypothesis Doxorubicin hydrochloride (DX) is one of the most powerful anticancer agents though its clinical use is impaired by severe undesired side effects. DX encapsulation in nanocarrier systems has been introduced as a mean to reduce its toxicity. Micelles of the nonionic triblock copolymers of poly(ethylene oxide) (PEO) and poly(propylene oxide) (PPO) (PEO-PPO-PEO), are very promising carrier systems. The positive charge of DX confines the drug to the hydrophilic corona region of the micelles. The use of mixed micelles of PEO-PPO-PEO copolymers and a negatively charged bile salt should favour the solubilization of DX in the apolar core region of the micelles. Experiments We st…
Multispectral filter arrays: Recent advances and practical implementation
2014
Thanks to some technical progress in interferencefilter design based on different technologies, we can finally successfully implement the concept of multispectral filter array-based sensors. This article provides the relevant state-of-the-art for multispectral imaging systems and presents the characteristics of the elements of our multispectral sensor as a case study. The spectral characteristics are based on two different spatial arrangements that distribute eight different bandpass filters in the visible and near-infrared area of the spectrum. We demonstrate that the system is viable and evaluate its performance through sensor spectral simulation. Multispectral filter arrays: Recent advan…
Entre socioterminologie et ethnoterminologie de l'entreprise
2016
The analysis of the designations of the commercial jobs reveals an important terminological vagueness between specialty language and common language, a vagueness conveyed by the multiplicity of the sources and of the concerned medias. Based on this observation, we propose a socioterminological and ethnoterminological study aiming at referencing the current terminological units in the speech of the company as well as of the employees. The international group Michelin, the subject of the study, presents a very rich terminological group but especially a terminology motivated by a particular historical and cultural context. Then the company becomes a model of thought and the analysis is an atte…
Ar izdarīto noziedzīgo nodarījumu saistīta apstākļa, kurš likumā nav paredzēts atzīšana par atbildību mīkstinošu apstākli vēsture Latvijas teritorijā…
2019
Adekvāta soda noteikšana ir viens no cilvēktiesību – tiesībām uz taisnīgu tiesu aspektiem, un spriedumus, ar kuriem vainīgajai personai piespriež sodu, tiesa pieņem gandrīz katru dienu. Soda noteikšanas kritēriji stingri uzskaitīti normatīvajos aktos, izņemot vienu – ar izdarīto noziedzīgo nodarījumu saistīta apstākļa, kurš likumā nav paredzēts atzīšana par atbildību mīkstinošu apstākli – robežas šo tiesību piemērošanā nav īsti skaidras, jo šī norma paver iespēju tiesību piemērotājam izvēlēties jebkādu apstākli, kas saistīts ar izdarīto noziedzīgo nodarījumu un, kurš nav paredzēts likumā, lai mīkstinātu vainīgajam atbildību. Darbā apskatīti problēmjautājumi par ar izdarīto noziedzīgo nodarī…
Soda noteikšanas vispārīgie principi
2018
Šī pētniecības darba mērķis ir aplūkot to, kā soda noteikšanas principus, nosakot vainīgajai personai soda veidu un mēru, ievēro tiesu praksē. Darbā autore pēta kritērijus, kas ir ņemami vērā pie soda veida un soda mēra noteikšanas, pēc 2013. gada 1. aprīļa, kad stājās spēkā 2012. gada 13. decembra likums “Grozījumi Krimināllikumā” un kā tie tiek ievēroti tiesu praksē. Autore norāda uz nepieciešamību tiesām sniegt motivāciju soda veida izvēlē, vērtējot ne tikai vainīgā personību, bet noziedzīgā nodarījuma raksturu, neaprobežojoties tikai ar noziedzīgā nodarījuma smaguma pakāpes konstatēšanu, un radīto kaitējumu, jo ar katru noziedzīgu nodarījumu tiek nodarīts kaitīgums. Tāpat autore norāda …
Extraordinary Performance of Carbon‐Coated Anatase TiO 2 as Sodium‐Ion Anode
2015
The synthesis of in situ polymer‐functionalized anatase TiO2 particles using an anchoring block copolymer with hydroxamate as coordinating species is reported, which yields nanoparticles (≈11 nm) in multigram scale. Thermal annealing converts the polymer brushes into a uniform and homogeneous carbon coating as proven by high resolution transmission electron microscopy and Raman spectroscopy. The strong impact of particle size as well as carbon coating on the electrochemical performance of anatase TiO2 is demonstrated. Downsizing the particles leads to higher reversible uptake/release of sodium cations per formula unit TiO2 (e.g., 0.72 eq. Na+ (11 nm) vs only 0.56 eq. Na+ (40 nm)) while the …
Soda noteikšana par slepkavību
2016
Darbā autore ir pētījusi tiesu praksi par soda noteikšanu par slepkavību, kā arī skatījusi teoriju par kriminālsoda un slepkavības jēdzienu. Darba mērķis ir veidot izpratni par soda noteikšanu vainīgajai personai par slepkavības izdarīšanu. Tika skatīts kriminālsoda mērķis un kā tas ir īstenojams, radot izpratni, gan par uzdevumiem, lai sasniegtu mērķi, gan par to realizāciju. Analizējot tiesu praksi, tika skatīti problēmjautājumi un prakses piemērošanas kļūdas un to atstātā ietekme uz piespriesto sodu. Darbā pētīts cik ļoti sodu ietekmē apsūdzētā personība, attieksme un arī uzvedība pēc noziedzīgā nodarījuma izdarīšanas. Darba rezultātā tiek apskatīts, kā tiesas neargumentēts spriedums var…
