On the mechanism of imine elimination from Fischer tungsten carbene complexes

2016

(Aminoferrocenyl)(ferrocenyl)carbene(pentacarbonyl)tungsten(0) (CO)5W=C(NHFc)Fc (W(CO)5(E-2)) is synthesized by nucleophilic substitution of the ethoxy group of (CO)5W=C(OEt)Fc (M(CO)5(1Et)) by ferrocenyl amide Fc-NH– (Fc = ferrocenyl). W(CO)5(E-2) thermally and photochemically eliminates bulky E-1,2-diferrocenylimine (E-3) via a formal 1,2-H shift from the N to the carbene C atom. Kinetic and mechanistic studies to the formation of imine E-3 are performed by NMR, IR and UV–vis spectroscopy and liquid injection field desorption ionization (LIFDI) mass spectrometry as well as by trapping experiments for low-coordinate tungsten complexes with triphenylphosphane. W(CO)5(E-2) decays thermally i…

Patterning of supported gold monolayers via chemical lift-off lithography

2017

The supported monolayer of Au that accompanies alkanethiolate molecules removed by polymer stamps during chemical lift-off lithography is a scarcely studied hybrid material. We show that these Au–alkanethiolate layers on poly(dimethylsiloxane) (PDMS) are transparent, functional, hybrid interfaces that can be patterned over nanometer, micrometer, and millimeter length scales. Unlike other ultrathin Au films and nanoparticles, lifted-off Au–alkanethiolate thin films lack a measurable optical signature. We therefore devised fabrication, characterization, and simulation strategies by which to interrogate the nanoscale structure, chemical functionality, stoichiometry, and spectral signature of t…

Patruunat liikunnan asialla : liikunta osana teollisuuden sosiaalitoimintaa Suomessa ja Jämsänkoskella 1920-1970-luvuilla

2014

Tutkielmassa kuvaillaan suomalaisten teollisuustyönantajien järjestämää liikuntatoimintaa 1920–1970-luvuilla valtakunnallisena ja paikallisena ilmiönä. Kirjallisuuskatsauksessa tarkastellaan, millaisia tavoitteita, toteutusmuotoja ja merkityksiä teollisuusyritysten liikuntatoiminta on saanut yhteiskunnassa tutkimusajanjaksona. Yhtyneet Paperitehtaat Oy:n (Yhtyneet) Jämsänkosken tehdasyhdyskuntaan syventyvällä tapaustutkimuksella kuvaillaan teollisuusyrityksen liikuntatoiminnan erityispiirteitä ja merkitystä paikallisen liikuntakulttuurin muotoutumisessa. Teollisuustyönantajien järjestämää liikuntatoimintaa on pidetty teollisuuden terveydellisen sosiaalitoiminnan osa-alueena. Teollisuuden so…

Assessment of Microstressors in Adults: Questionnaire Development and Ecological Validation of the Mainz Inventory of Microstressors

2020

Background Many existing scales for microstressor assessment do not differentiate between objective (ie, observable) stressor events and stressful cognitions or concerns. They often mix items assessing objective stressor events with items measuring other aspects of stress, such as perceived stressor severity, the evoked stress reaction, or further consequences on health, which may result in spurious associations in studies that include other questionnaires that measure such constructs. Most scales were developed several decades ago; therefore, modern life stressors may not be represented. Ecological momentary assessment (EMA) allows for sampling of current behaviors and experiences in real…

Neuronal effects of Sugammadex in combination with Rocuronium or Vecuronium.

2017

Rocuronium (ROC) and Vecuronium (VEC) are the most currently used steroidal non-depolarizing neuromuscular blocking (MNB) agents. Sugammadex (SUG) rapidly reverses steroidal NMB agents after anaesthesia. The present study was conducted in order to evaluate neuronal effects of SUG alone and in combination with both ROC and VEC. Using MTT, CASP-3 activity and Western-blot we determined the toxicity of SUG, ROC or VEC in neurons in primary culture. SUG induces apoptosis/necrosis in neurons in primary culture and increases cytochrome C (CytC), apoptosis-inducing factor (AIF), Smac/Diablo and Caspase 3 (CASP-3) protein expression. Our results also demonstrated that both ROC and VEC prevent these…

Sustaining Attention for a Prolonged Duration Affects Dynamic Organizations of Frequency-Specific Functional Connectivity

2020

Sustained attention encompasses a cascade of fundamental functions. The human ability to implement a sustained attention task is supported by brain networks that dynamically formed and dissolved through oscillatory synchronization. The decrement of vigilance induced by prolonged task engagement affects sustained attention. However, little is known about which stage or combinations are affected by vigilance decrement. Here, we applied an analysis framework composed of weighted phase lag index (wPLI) and tensor component analysis (TCA) to an EEG dataset collected during 80 min sustained attention task to examine the electrophysiological basis of such effect. We aimed to characterize the phase…

Particle balance and return loops for microplastics in a tertiary-level wastewater treatment plant.

2021

Highlights: Dewatering by centrifugation was a step that removed a high number of MPs from the sludge. Sludge retained especially the fibrous microplactics. Reject water transported microplastics inside a wastewater treatment plant. Disc filter-based tertiary treatment ensured removal of 99% of microplastics in wastewater. Microplastics (MPs) from households, stormwater, and various industries are transported to wastewater treatment plants (WWTPs), where a high proportion of them are captured before discharging their residuals to watersheds. Although recent studies have indicated that the removed MPs are mainly retained in wastewater sludge, sludge treatment processes have gained less atten…

Riconsiderare l’identità delle donne musulmane nell’Egitto post-rivoluzionario

2019

Questo articolo esplora alcune forme dell’identità femminile nell’Egitto post-rivoluzionario, quale si manifesta in due documenti pubblicati dopo la Rivoluzione del 2011 sui diritti delle donne musulmane. Sono il Documento di al–Azhar (2013) e la Dichiarazione di Alessandria (2014), concordi nel ribadire il valore delle donne e i diritti garantiti loro dalla shari‘a. L’uno e l’altra hanno visto il coinvolgimento delle femministe islamiche. Si descrivono anche le possibilità di collaborazione tra al-Azhar e le femministe islamiche, per fondare una conoscenza religiosa-femminista autoctona e sensibile al genere. Tale collaborazione è utile per l’affermazione di un’identità femminile rispettos…
