Biodegradable mulching film degradation in soil in Italy
No full text<p><span>The biodegradable mulching samples underwent a visible degradation process in the soil at the experimental field of the University of Bari (Italy). The surface area of each sample clearly presented gaps that increased in size over time. After 42 days of burial the surface loss was 1.30%, reaching 56.70% on the last sampling.</span></p>

Dataset for Selective Precipitation of REE-rich Aluminium Phosphate from Lithium Enriched Slag Leachate
No full text<p>Currently, recycling of spent lithium-ion batteries is carried out using mechanical, pyrometallurgical and hydrometallurgical methods and their combination. The aim of this article is to study a part of pyro-hydrometallurgical processing of spent lithium-ion batteries which includes lithium slag hydrometallurgical treatment and refining obtained leachate. Lithium slag intended for leaching experiments contains 3,68 % of Li; 11,02 % of Al; 1,17 % of Co; 1,71 % of Cu and other metals in minority content. Leaching step was realized via dry digestion that is an effective method capable of transferring over 99% of the present metals such as Li, Al, Co, Cu and others to the leachate. The highest content in leachate reached Al (2666 µg/mL) and Li (2239 µg/mL). Extraction of metals from leachate can be conducted using various methods, with precipitation being the most used. In this work, the influence of two types of precipitation agent (NaOH, Na3PO4) on precipitation efficiency of Al and Li losses was investigated. It was found that the precipitation of aluminium with NaOH can result in the co-precipitation of lithium, causing total lithium losses up to 40 %. As suitable precipitating agent for complete Al removal from Li leachate with a minimal loss of lithium (less than 2 %), crystalline Na3PO4 was determined under following condition: pH = 3, 400 rpm, 10 minutes, room temperature. Analysis confirmed that, in addition to aluminium, the precipitate also contains REE La (3.4%), Ce (2.5%), Y (1.3%), Nd (1%) and Pr (0.3%), which selective recovery will be the subject of further study.</p>

New species in Galeommatoidea (Bivalvia) from Namibia
No full textFour new species in the superfamily Galeommatoidea (Bivalvia) were found in sediment samples from the continental shelf and upper bathyal slope off Namibia, SW Africa: Kurtiella namibiensis n. sp., Bornia walvisensis n. sp., Scacchia aartseni n. sp. and Scacchia huberi n. sp. One live specimen of Bornia walvisensis n. sp. was brooding. A commensal relationship is likely between Bornia walvisensis n. sp. and the decapod host Kraussillichirus kraussi (Stebbing, 1900)

Dataset of "Elucidation of factors shaping reactivity of 5'-deoxyadenosyl – a prominent organic radical in biology"
No full text<p>This study investigates the factors modulating the reactivity of 5'-deoxyadenosyl (5'dAdo•) radical, a potent hydrogen atom abstractor, present in the active sites of radical SAM enzymes, but otherwise undergoing a rapid self-decay in aqueous solution. Here, we compare hydrogen atom abstraction (HAA) reactions between native substrates of radical SAM enzymes and 5'dAdo• in aqueous solution and in two enzymatic microenvironments and reveal that HAA efficiency of 5'dAdo• depends on (i) formation of 5'dAdo• in a pre-ordered complex with a substrate, which attenuates the unfavorable effect of substrate:5'dAdo• complex formation, (ii) hindering the conformational change associated with self-decay by performing the reaction in a tight cavity. The enzymatic cavity, however, does not have a strong effect on the HAA activity of 5'dAdo•. We performed an analysis of HAA performed by 5'dAdo• based on the three-component thermodynamic model incorporating the diagonal effect of the free energy of reaction, and the off-diagonal effect of asynchronicity and frustration. The study is based on the straightforward relationship between the off-diagonal thermodynamic effects and the electronic-structure descriptor – the redistribution of charge between the reactants during the reaction. It allows to access HAA-competent redox and acidobasic properties of 5'dAdo• that are otherwise unavailable due to its instability upon one-electron reduction and protonation. The results show that all reactions feature a favourable thermodynamic driving force and tunneling, the latter of which lowers systematically barriers by ~2 kcal mol-1. In addition, most of the reaction experience a favourable off-diagonal thermodynamic contribution. In HAA reactions, 5'dAdo• acts as a weak oxidant as well as a base, also 5'dAdo•-promoted HAA reactions proceed with quite low degree of asynchronicity of proton and electron transfer. Finally, the study elucidates the crucial and dual role of asynchronicity. It directly lowers the barrier as a part of the off-diagonal thermodynamic contribution, but also indirectly increases the non-thermodynamic part of the barrier by controlling the adiabatic coupling between proton and electron transfer. The latter signals that the reaction proceeds as a hydrogen atom transfer rather than a proton-coupled electron transfer.</p>

<p><br>Samotné ukážky považujeme za veľmi dôležité pre ďalšie využitie a zdokonaľovanie modelu, keďže ďalší bádatelia získajú predstavu o podobnom alebo odlišnom písaní vlastných dokumentov, ktoré chcú prepisovať. <br><strong>Boli dosiahnuté hodnoty Train Set: 4,90 % a Validation Set: 5,30 %.</strong><br>Vytvorenie modelu SSM1 na serveri Transkribus trvalo dva dni, 5 hodín, 16 sekúnd, teda <strong>53 hodín a 58 minút.</strong> Proces tvorby bol ukončený po <strong>174 cykloch</strong> (epochách). <br>Model SSM1 je prvým pokusom na Slovensku o vytvorenie nástroja, prostredníctvom ktorého by bolo možné automaticky sprístupniť určité typy ručne písaných dokumentov, ktoré sa podobajú fontom používaným na ich tvorbu. <br><strong>ID63569 Slovak Supermodel M1 (SSM1)</strong> nemožno v žiadnom prípade považovať za definitívny univerzálny model na prepis historických rukopisov slovenskej proveniencie všetkých typov a období. Rozmanitosť písiem a štýlov rukopisu je nekonečná a vytvorenie optimálneho agregovaného modelu je výzvou pre ďalších výskumníkov a nadšencov v nasledujúcich rokoch. <br>Veríme však, že náš prvý agregovaný model SSM1 môže uľahčiť automatický prepis ďalších analogických rukopisov. <br>Riešiteľský tím plánuje sprístupniť datasety v rámci udržateľnosti projektu v rokoch 2024-2028 prednostne na výskumné a vzdelávacie účely pre inštitúcie a výskumníkov, ktorí chcú prispieť k vytvoreniu modelu historických rukopisov v západoslovanských jazykoch, respektíve jazyky slovenského a českého pôvodu. <strong>Copyright: CC BY-NC-SA.</strong><br>Samozrejme, takýto automatický prepis neprinesie okamžite uspokojivé výsledky. Môže však uľahčiť „hrubý“ automatický prepis ďalších stránok krok za krokom, ich ručnú opravu na stav GT a následné použitie väčších súborov údajov GT na spresnenie nového modelu založeného na našom SSM1. Po vytvorení ďalších stoviek a tisícok stránok GT bude možné pristúpiť k tvorbe ďalších generácií nových modelov založených na SSM1. Vývoj by mohol pokračovať pre rukopisy s modelmi nových generácií SSM2, SSM3 atď. Respektíve pre tlače a sadzbu (P-Print), ako sú supermodely SSP1, SSP2, SSP3 atď. (Google translate)</p>
