Preparation of tungstophosphoric acid/cerium-doped NH2-UiO-66 Z-scheme photocatalyst: a new candidate for green photo-oxidation of dibenzothiophene a…
2021
International audience; The goal of this study was to introduce an effective visible-light induced photocatalytic system with a good ability for photocatalytic oxidative desulfurization (PODS) and denitrogenation (PODN) using molecular oxygen (O2) as an oxidant. In this regard, tungestophosphoric acid (PW12) was supported onto cerium-doped NH2-UiO-66 (PW12/Ce-NUiO-66) and employed for the photo-oxidation of dibenzothiophene (DBT) and quinoline (Qu). Herein, using cerium (Ce) as a “mediator” facilitated the separation of charge carriers, while NH2-UiO-66 remarkably enhanced the surface area with plentiful adsorption sites and shifted the adsorption edge of PW12to the visible region. The sum …
More than meets the Eye : Towards a Post-materialist Model of Consciousness
2016
Commonly accepted models of human consciousness have substantial shortcomings, in the sense that they cannot account for the entire scope of human experiences. The goal of this article is to describe a model with higher explanatory power, by integrating ideas from psychology and quantum mechanics. In the first part, the need for a paradigm change will be justified by presenting three types of phenomena that challenge the materialistic view of consciousness. The second part is about proposing an alternative view of reality and mind–matter manifestation that is able to accommodate these phenomena. Finally, the ideas from the previous parts will be combined with the psychological concepts deve…
Relating with the other in naturecultures : ethics and well-being in Elfquest comics
2015
Tutkielma tarkastelee eettistä Toisen kohtaamista Elfquest -sarjakuvassa. Elfquest on yhdysvaltalaisten Wendy ja Richard Pinin vuodesta 1978 lähtien omakustanteena julkaisema populaari fantasiagenreen kuuluva sarjakuvasarja. Se sijoittuu Kahden kuun maailmaan, jota asuttavat mm. haltiat, peikot ja ihmiset. Elfquest rakentuu haltioiden alkuperän, autenttisuuden ja identiteetin etsinnän varaan ja siinä korostuvat erilaisten elämäntyylien ja maailmankuvien sovittelu ja yhteenkuuluvuus. Mukailen etiikan määrittelyssäni Emmanuel Levinasin filosofiaa, jonka mukaan Minä tulee subjektiksi vastuussaan Toista kohtaan. Tämä eettinen, interpersoonallinen suhde edeltää ontologiaa eli olemista, tietämist…
Volfganga Velša dzirdes kultūras koncepts
2018
Volfganga Velša dzirdes kultūras jēdzienā ir ietverta metateorētiska Rietumu kultūras filozofijas kritika, apspriežot Rietumu filozofiskajā diskursā izveidojušās okulārcentriskās tendences. Abām maņām ir atšķirīgi fenomenoloģiskie apraksti: dzirde iesaistās pasaulē, uzklausa un ieklausās, nevis, kā to dara redze, objektivizē, distancējas un sniedz prioritāti subjektu-objektu attiecībām. Tā rezultātā, sākot ar senajiem grieķiem un kulminējot apgaismības laikmetā, redzes metaforas filozofijā ir veidojušas ne tikai Rietumu epistemoloģiskās, bet arī sociālās, kulturālās un ētiskās nostādnes. Atsacīšanos no redzes hegemonijas jeb okulārcentrisma mūsu filozofiskajā valodā Velšs uzskata par nepiec…
Protein recovery as a resource from waste specifically via membrane technology : from waste to wonder
2021
Economic growth and the rapid increase in the world population has led to a greater need for natural resources, which in turn, has put pressure on said resources along with the environment. Water, food, and energy, among other resources, pose a huge challenge. Numerous essential resources, including organic substances and valuable nutrients, can be found in wastewater, and these could be recovered with efficient technologies. Protein recovery from waste streams can provide an alternative resource that could be utilized as animal feed. Membrane separation, adsorption, and microbe-assisted protein recovery have been proposed as technologies that could be used for the aforementioned protein re…
The paradox of endogenous poverty line in the poverty indices
2007
february 23-25, 2007; When measuring poverty, the poverty line is considered to be relatively determined as a percentage of the median income or as a percentage of the average income so as to allow international comparisons. The poverty line relative to the median income may be described as endogenous in contrast with the poverty line relative to the average income which may be described as exogenous because it is independent of the normalized distribution of incomes. As the existing literature is focused on the properties of the indices but not on the respective interest of the endogenous and exogenous poverty lines, this paper compares the two definitions of the relative poverty. The Rela…
Case study of the Kibera slum project
2011
The aim of this study is to explore social resilience and civic entrepreneurship in self-help organizations. The purpose is to find out how social resilience can be built through entrepreneurial activities. The issue is explored in a self-help organization in the Kibera slum. The intention is to contribute on the discussion on the best practises of self-help organization and the key elements behind their success or failure in developing countries. The thesis is divided into two main parts: the first one presents the key terms and a literary review on the concepts of social resilience and civic entrepreneurship. The second part is a case study on the cooperation of two non-governmental organ…
School-related bullying : analysis of bullying preventive programs and analysis of power from perspective of social philosophy
2017
The present thesis is dedicated to a problem of school-related bullying. Bullying is a global problem that affect big number of students, and has serious short- and long-term consequences. Bullying can be manifested in various forms: it can be physical, emotional, and lately also cyber-bullying. Being a complex phenomenon, bullying can be difficult to identify, to intervene or prevent. It originates from power imbalance in a social group, and can target anyone who qualifies as “different” in any way. In order to provide analysis of bullying, in the present paper are presented definitions and analysis of the phenomenon of bullying as well global statistics of bullying across the countries in…
Live as you wish and ruin your life : Haybron on unhappiness and well-being
2014
This thesis examines the concepts of happiness, unhappiness and well-being developed by philosopher Daniel Haybron in his book The Pursuit of Unhappiness. The central thesis of this book is that human beings are not psychologically well-adapted to live in liberal societies, which are understood in this approach as option-rich environments. According to Haybron, in liberal societies people have freedom to choose whatever they want from a myriad of options in the pursuit of happiness. This condition, however, makes people prone to committing serious mistakes in choosing the options that are prudentially good for them. Haybron calls this phenomenon “systematic imprudence.” This systematic impr…
Dal segno alla società. Il pensiero di Mead come trascrizione sociologica della semiotica di Peirce
2006
L'articolo mostra come il pensiero di Mead, pur partendo dagli stessi presupposti di Peirce e condividendone gli assunti fondamentali, presenta alcune caratteristiche peculiari che ne permettono una fruttuosa ricezione ai sociologi
