Toward Sustainable PLA-Based Multilayer Complexes with Improved Barrier Properties

2019

Poly(lactic acid) or PLA is currently considered as one of the most promising substitutes of conventional plastics, with low environmental impact, especially for food packaging applications. Nevertheless, some drawbacks, such as high permeability to oxygen, are still limiting its industrial applications. The objective of this study was to highly increase the oxygen barrier performance of PLA without compromising its sustainable nature and following the principles of circular economy perspective. Coproducts coming from mill industries, such as wheat gluten proteins (WG), were used to produce PLA-WG-PLA multilayer complexes with improved barrier performance. Different technologies of industri…

Effectiveness of spinosad and mineral oil for control of Grapholita funebrana Treitschke in organic plum orchards

2012

An experiment was conducted in an organic plum orchard in Sicily to evaluate the damage caused by the plum moth Grapholita funebrana (Treitschke) to three plum cultivars (Angeleno, Friar, and Stanley) and to evaluate plum moth control provided by mineral oil applied every 20 days (Moil), spinosad applied every 10 days (S10), or spinosad and mineral oil applied alternately (S/Moil). Treatment application began when eggs were first observed on fruits. S10 and S/Moil effectively reduced plum moth damage on all cultivars but Moil did not. Plum moth infestation was significantly lower on Stanley than on Friar and Angeleno.

PEDOT saturošu nanošķiedru iegūšana, izmantojot elektrovērpšanas metodi, un to elektrisko īpašību raksturošana

2020

Šajā darbā ir veikti pētījumi ar PEDOT:PSS polimēra nanodiegiem un plānajām kārtiņām. Nanodiegi tika iegūti izmantojot elektrovērpšanas metodi. Tika pētītas iegūto paraugu īpašības – elektriskā vadītspēja un Zēbeka koeficients, kā arī nanodiegu dimensionālie lielumi. Šī pētījuma mērķis ir iegūt nanodiegus ar pēc iespējas augstāku elektrisko vadītspēju. Tas tiek panākts palielinot PEDOT:PSS polimēra koncentrāciju šķīdumos, pārbaudot arī šķīdumu, kurā nav pievienots PEDOT:PSS polimērs. Ir izmērītas īpatnējās elektriskās vadītspējas un Zēbeka koeficienti nanodiegu un plāno kārtiņu paraugiem. Iegūtās vadītspējas un Zēbeka koeficienti ir salīdzināti savā starpā, lai saprastu elektrovērpšanas pro…

Functional Bionanocomposite Fibers of Chitosan Filled with Cellulose Nanofibers Obtained by Gel Spinning

2021

Extremely high mechanical performance spun bionanocomposite fibers of chitosan (CHI), and cellulose nanofibers (CNFs) were successfully achieved by gel spinning of CHI aqueous viscous formulations filled with CNFs. The microstructural characterization of the fibers by X-ray diffraction revealed the crystallization of the CHI polymer chains into anhydrous chitosan allomorph. The spinning process combining acidic–basic–neutralization–stretching–drying steps allowed obtaining CHI/CNF composite fibers of high crystallinity, with enhanced effect at incorporating the CNFs. Chitosan crystallization seems to be promoted by the presence of cellulose nanofibers, serving as nucleation sites for the gr…

Struttura galleggiante ad elevata stabilità (Floating structure with high stability)

2015

DESCRIZIONE GENERALE La struttura galleggiante innovativa è composta da diversi elementi modulari collegati fra loro. La composizione modulare della struttura consente di conferirle la lunghezza dettata dalle particolari esigenze da soddisfare. Tipiche applicazioni della struttura galleggiate innovativa sono i pontili, le passerelle pedonali o ciclabili su specchi d'acqua, e in generale le opere finalizzate a consentire lo spostamento di persone, merci e/o veicoli fra punti di uno specchio d'acqua (marino o lacustre) utilizzando strutture galleggianti. Ogni modulo, lungo 10-15 m, è tenuto a galla dalla spinta di Archimede sulle sue parti immerse (le carene), spinta che nella struttura innov…

.Single-Ion Magnetic Behaviour in an Iron(III) Porphyrin Complex: A Dichotomy Between High Spin and 5/2-3/2 Spin Admixture

2020

International audience; A mononuclear iron(III) porphyrin compound exhibiting unexpectedly slow magnetic relaxation, which is a characteristic of single-ion magnet behaviour, is reported. This behaviour originates from the close proximity (approximate to 550 cm(-1)) of the intermediate-spinS=3/2 excited states to the high-spinS=5/2 ground state. More quantitatively, although the ground state is mostlyS=5/2, a spin-admixture model evidences a sizable contribution (approximate to 15 %) ofS=3/2 to the ground state, which as a consequence experiences large and positive axial anisotropy (D=+19.2 cm(-1)). Frequency-domain EPR spectroscopy allowed them(S)= |+/- 1/2⟩->|+/- 3/2&Rig…

Disability, illness and physical activity: a (post)qualitative research

2019

This PhD thesis is an assemblage of papers addressing 1) disability, illness and physical activity; and 2) (post)qualitative inquiry. The thesis tackles the case of Patrick, a man living with poor prognostic cancer and paraplegia. Overall, it examines in-depth how narrative and material forces acted by shaping Patrick’s struggle of becoming, and which role physical activity played in his life post-diagnosis. Data was obtained from life-story interviews, participant-produced images in different formats and object interviews, as well as three years of informal interactions with Patrick. The selection of data collection techniques was subjected to ethical considerations meant to preserve Patri…

Preoperativ oppvarming av pasienter med hoftebrudd : Kan preoperativ oppvarming med varmluftsteppe redusere intraoperativt temperaturfall hos pasient…

2018

Masteroppgave spesialsykepleie ME519 – Universitetet i Agder 2018 Background: Hip fractures are a common cause of hospitalization and are linked with high morbidity and mortality rates. It is therefore important to optimize every aspect of their treatment to minimize complications. The Nurse Anesthetist plays an important role in preventing complications related to both surgery and anesthesia. Purpose: The aim of this project is to evaluate the quality of the current procedure for preoperative prevention of hypothermia in our hospital. We wanted to investigate if this procedure for preventing hypothermia is as effective as preoperative warming with a forcedair system in hip fracture patient…
