Monitoring tropical forests under a functional perspective with satellite-based vegetation optical depth.
2020
Monitoring ecosystem functions in forests is a priority in a climate change scenario, as climate-induced events may initially alter the functions more than slow-changing attributes, such as biomass. The ecosystem functional properties (EFPs) are quantities that characterize key ecosystem processes. They can be derived by point observations of gas and energy exchanges between the ecosystems and the atmosphere that are collected globally at FLUXNET flux tower sites and upscaled at ecosystem level. The properties here considered describe the ability of ecosystems to optimize the use of resources for carbon uptake. They represent functional forest information, are dependent on environmental dri…
The liability of the shipmaster in early modern law: comparative (and practice-oriented) remarks
2017
This article deals with the liability of the shipmaster in early modern law in civil and common law, focusing on the approach of Italian and (to a lesser extent) also Iberian courts on the one hand, and on that of common law courts (mostly the King's Bench) on the other. The practice-oriented approach is deliberate: the article seeks to understand what the actual position of the carrier was, not how did learned jurists classify it. Once distinguished practice from dogmatic elaborations (especially for the civil law), this work then proceeds to compare the rules applicable in the two different legal systems. Common law courts imposed strict liability on the shipmaster, for it qualified the c…
Promuovere l’inclusione attraverso il Programma Motorio Abilità Diverse
2023
Gli studi svolti nell’ambito delle neuroscienze, delle scienze motorie e le conseguenti applicazioni didattiche, hanno posto in evidenza la necessità di avviare processi di progettazione e organizzazione dei contenuti, delle modalità organizzative e delle metodologie in educazione fisica e nell’avviamento allo sport, per integrare e modulare fattori inerenti la quantità inclusiva e promuovere pratiche adattive e preventive per raggiungere sempre più persone con diverse esigenze. Le politiche nazionali e sovranazionali, attraverso il PNRR, sottolineano come l’educazione motoria rivesta un ruolo privilegiato per contrastare i fenomeni dell’esclusione e della marginalizzazione, nel periodo com…
L'IMPATTO DELLA DIAGNOSI DI STERILITÀ E DEI TRATTAMENTI DI PMA SULL'UOMO: UNA RASSEGNA DELLA LETTERATURA
2016
Questo contributo prende in esame i vissuti e l’adattamento dell’uomo a seguito della diagnosi di sterilità, nonché il suo approccio ai percorsi di PMA e le principali differenze con l’esperienza femminile. In realtà, il principale focus di interesse della maggior parte degli studi risulta essere la componente femminile della coppia mentre è ormai noto come la genitorialità risulti essenziale anche per l’identità maschile e la mancata transizione ad essa possa determinare nell’uomo gravi ricadute in termini di bassa autostima, alterazione dell’immagine corporea, percezione della propria mascolinità. Il lavoro è orientato ad identificare quali componenti psicologiche giocano un ruolo nell’e…
Au pair programma: dalībnieku iesaistes iemesli un ieguvumi
2016
Bakalaura darbā “Au pair programma: dalībnieku iesaistes iemesli un ieguvumi” analizēti jauniešu iesaistes iemesli un ieguvumi no au pair programmas, izmantojot racionālās izvēles un sociālās apmaiņas teoriju. Pētījuma mērķis ir noskaidrot iemeslus un ieguvumus, kādēļ dalībnieki iesaistās au pair programmā. Lai sasniegtu darba mērķi, izmantota kvalitatīvās pētniecības pieeja. Veiktas divpadsmit daļēji strukturētas intervijas. Analīzes daļā galvenās kategorijas tika atvedinātas no iepriekš aprakstītas teorijas. Secināts, ka ne visi dalībnieki rīkojas racionāli, kā to paredz teorijā aprakstītais, un kultūras dažādība spēlē lielu lomu starp apmaiņas dalībniekiem apmaiņas laikā. Tomēr ar iesais…
Spectroscopic and conformational properties of size-fractions separated from a lignite humic acid
2007
Abstract A lignite humic acid (HA) was fractionated by preparative high performance size-exclusion chromatography (HPSEC) in seven different size-fractions. The size-fractions were characterized by cross polarization (CP) magic angle spinning (MAS) 13 C NMR spectroscopy and a further analytical HPSEC elution under UV and fluorescence detection. The alkyl hydrophobic components mainly distributed in the largest molecular-size-fraction, whereas the amount of oxidized carbons increased with decreasing size of fractions. Cross polarization time ( T CH ) and proton spin-lattice relaxation time in the rotating frame ( T 1 ρ (H)) were measured from variable contact time (VCT) experiments. The bulk…
Adsorption of dissolved organic matter on clay minerals as assessed by infra-red, CPMAS 13C NMR spectroscopy and low field T1 NMR relaxometry
2011
Abstract Dissolved organic matter (DOM) is a very important environmental constituent due to its role in controlling factors for soil formation, mineral weathering and pollutant transport in the environment. Prediction of DOM physical–chemical properties is achieved by studying its chemical structure and spatial conformation. In the present study, dissolved organic matter extracted from compost obtained from the organic fraction of urban wastes (DOM-P) has been analysed by FT-IR, CPMAS 13C NMR spectroscopy and 1H T1 NMR relaxometry with fast field cycling (FFC) setup. While the first two spectroscopic techniques revealed the chemical changes of dissolved organic matter after adsorption eith…
CHARACTERIZATION OF CHEMICAL AND PHYSICAL PROPERTIES OF BIOCHAR FOR ENERGY PURPOSES AND ENVIRONMENTAL RESTORATION
2014
Biochar production processes as well as its various applications provide numerous benefits to both environment and economy (Lehmann et al., 2006; Basu, 2010). However, understanding the physicochemical structure of this valuable product has to be improved in order to be able to obtain the aforementioned benefits and to avoid environmental costs. In this study, chicken or poultry manure (PM) was chosen as feedstock for biochar preparation. This biomass is traditionally used by farmers as an effective organic fertilizer (Chan et al., 2008). Indeed, it is considered a valuable source for readily available plant nutrients, such as N, P, K and other micronutrients (Huang et al., 2011). Notwithst…
PSMA6 (rs2277460, rs1048990), PSMC6 (rs2295826, rs2295827) and PSMA3 (rs2348071) genetic diversity in Latvians, Lithuanians and Taiwanese
2014
PSMA6 (rs2277460, rs1048990), PSMC6 (rs2295826, rs2295827) and PSMA3 (rs2348071) genetic diversity was investigated in 1438 unrelated subjects from Latvia, Lithuania and Taiwan. In general, polymorphism of each individual locus showed tendencies similar to determined previously in HapMap populations. Main differences concern Taiwanese and include presence of rs2277460 rare allele A not found before in Asians and absence of rs2295827 rare alleles homozygotes TT observed in all other human populations. Observed patterns of SNPs and haplotype diversity were compatible with expectation of neutral model of evolution. Linkage disequilibrium between the rs2295826 and rs2295827 was detected to be c…
