La resistenza di interfaccia calcestruzzo poroso-terreni a grana fina per il consolidamento di pendii mediante trincee drenanti profonde

2022

Le trincee drenanti profonde rappresentano uno dei metodi più efficaci per la mitigazione del rischio da frana, in pendii con falda idrica. Esse sono realizzate mediante pannelli o pali secanti. Il riempimento è costituito di calcestruzzo poroso o materiale granulare. Se le trincee sono adeguatamente “innestate” nel terreno stabile e il materiale di riempimento ha sufficiente resistenza e rigidezza come il calcestruzzo poroso, si ha ulteriore in-cremento di resistenza a taglio per effetto shear keys, oltre a quello derivante dalla riduzione delle pressioni in-terstiziali. L’incremento di resistenza è dovuto sia alla resistenza all’interfaccia calcestruzzo–terreni sia a quella intrinseca del…

Fluorination of some highly functionalized cycloalkanes: chemoselectivity and substrate dependence.

2017

A study exploring the chemical behavior of some dihydroxylated β-amino ester stereo- and regioisomers, derived from unsaturated cyclic β-amino acids is described. The nucleophilic fluorinations involving hydroxy–fluorine exchange of some highly functionalized alicyclic diol derivatives have been carried out in view of selective fluorination, investigating substrate dependence, neighboring group assistance and chemodifferentiation.

‘It is important at this point to make clear that this study is not “anti-iPad”’ : Ed-Tech speak around iPads in educational technology research

2020

This position paper contributes to the field of critical educational technology (Ed-Tech) research by providing empirical evidence for the qualities of the phenomenon known as Ed-Tech speak. The research question, how does Ed-Tech speak in research articles about Apple's iPad contribute to promoting and validating the importance and utility of the iPad for teaching and learning, is addressed by applying critical genre analysis to investigate empirical research articles discussing the use of iPads in institutional education. As a result, four categories were formed: the self-evident importance of iPads, overgeneralization of references, the use of strong reporting verbs (to boost weak refere…

5-Imino-3,4-diphenyl-1H-pyrrol-2-one

2014

The title compound, C16H12N2O, exists in the crystalline state as the 5-imino-3,4-diphenyl-1H-pyrrol-2-one tautomer. The dihedral angles between the pyrrole and phenyl rings are 35.3 (2) and 55.3 (2)°. In the crystal, inversion dimers linked by pairs of N—H...N hydrogen bonds generate a graph-set motif ofR22(8)viaN—H...N hydrogen bonds.

2,3-Di­phenyl­male­imide 1-methyl­pyrrol­idin-2-one monosolvate

2014

In the title compound, C16H11NO2·C5H9NO, the dihedral angles between the maleimide and phenyl rings are 34.7 (2) and 64.8 (2)°. In the crystal, the 2,3-diphenylmaleimide and 1-methylpyrrolidin-2-one molecules form centrosymmetrical dimersviapairs of strong N—H...O hydrogen bonds and π–π stacking interactions between the two neighboring maleimide rings [centroid–centroid distance = 3.495 (2) Å]. The dimers are further linked by weak C—H...O and C—H...π hydrogen bonds into a three-dimensional framework.

Sosiaalialan ammattilaiset halukkaita osallistumaan asiakastietojärjestelmien kehittämiseen – osallistumistavoissa kehitettävää

2020

Tietojärjestelmien kehittämistyön lähtökohtana tulee olla vahva ymmärrys käyttäjien tarpeista, tehtävistä sekä toimintaympäristöstä. Lisäksi suunnitteluratkaisuja tulee arvioida käyttäjien kanssa kehittämisprosessin aikana ja käyttöönoton jälkeen. Vaikka kansallisesti kohdennetaan runsaasti resursseja tietojärjestelmäpalveluiden kehittämiseen, sosiaalialalta tutkimusta aiheesta löytyy niukasti. Sosiaalialan ammattilaisten kokemuksia asiakastietojärjestelmien kehittämistyöstä kartoitettiin osana keväällä 2019 toteutettua valtakunnallisesta käyttäjäkokemuskyselyä. Kysymyksissä käsiteltiin kokemuksia yhteistyöstä tietojärjestelmätoimittajan kanssa, osallistumisesta kehittämistyöhön ja osallist…

The Ability of Water Hyacinth (Eichhornia crasipes Mart.) and Water Lettuce (Pistia stratiotes Linn.) for Reducing Pollutants in Batik Wastewater

2021

Batik produced by craftsmen is categorized as a small and medium industry. The problem of Batik production is less attention to the environment because the craftsmen lived in the middle of a residential area that has inexperience. One of less attention to the environment is no treatment of wastewater that reaches up to 95 % (61.9 L each cloth). Thus it polluted the river. This research aimed to treat the wastewater of Batik production by using phytoremediation. In this study, phytoremediation was carried out in three tanks in series using Eichhornia crassipes and Pistia stratiotes which are abundant in Indonesia. The treated wastewater was evaluated for its ammonia and chromium (Cr). The re…

Dynamic of Components Leachate from Experimental Fertilizers in Leaching Test

2018

Organic matter contained in the waste of food industry or occurring in the households, in the absence of contamination with other kind of waste, may be used to create a “fertiliser”, which could be even reused in the organic production of arable crops. Particular attention is drawn to the fertilisers which may be applied in the case of amateur cultivation of pot plants and in the allotment gardens. The paper presents the results of research regarding the dynamics of the release of nutrients from tablets created with the help of encapsulation of the mixture manufactured from solvent extraction waste of coffee (SCG), modified by the ash obtained from low temperature burning of biomass. In thi…

Reductive modification of genetically encoded 3-nitrotyrosine sites in alpha synuclein expressed in E.coli

2019

Tyrosine nitration is a post-translational protein modification relevant to various pathophysiological processes. Chemical nitration procedures have been used to generate and study nitrated proteins, but these methods regularly lead to modifications at other amino acid residues. A novel strategy employs a genetic code modification that allows incorporation of 3-nitrotyrosine (3-NT) during ribosomal protein synthesis to generate a recombinant protein with defined 3-NT-sites, in the absence of other post-translational modifications. This approach was applied to study the generation and stability of the 3-NT moiety in recombinant proteins produced in E.coli. Nitrated alpha-synuclein (ASYN) was…
