Održive mere za unapređenje gajenja reofilnih vrsta riba – preliminarni rezultati gajenja klena (squalius cephalus)

U jednom delu životnog ciklusa, posebno tokom ranih stadijuma razvoja većina reofilnih riba nastanjuje visoko produktivna obalska i lentična staništa reka. Ovakva staništa su često degradirana usled regulacije rečnih obala i toka reka kao i izgradnje brana. Nekada jedna od najrasprostranjenijih slatkovodnih ciprinida Evrope, klen (Squalius cephalus L.), tokom poslednje decenije pokazuje znake opadanja brojnosti u nekim rekama. Iako nema neku posebnu ekonomsku vrednost, ova riba je cenjena u sportskom ribolovu, ali pre svega ona je autohtona vrsta Evrope koja ukazuje na ekološki status reka, pa se njeno prisustvo u vodenim ekosistemima ne sme zanemariti. Osim mera za očuvanja prirodnih staništa, brojnost populacije riba se održava i poribljavanjem. Produkcija mlađi je relativno zahtevna faza u gajenju ove vrste riba, posebno u segmentu obezbeđivanja dovoljno kvalitetne hrane. U cilju smanjivanja cene ove faze gajenja od velikog značaja može biti primena održivih mera koje bi poboljšale iskoristljivost prirodnih resursa. Shodno tome, cilj ovog rada je bio da se istraži efikasnost održivih mera u gajenju mlađih uzrasnih kategorija klena (1+) radi poribljavanja prirodnih staništa. Istraživanje je obavljeno tokom 7 meseci, od aprila do oktobra 2014. godine u 8 identičnih eksperimentalnih ribnjačkih bazena Fakulteta za ribarstvo i zaštitu voda (Univerzitet Južna Bohemija), u okviru AQUAECXEL FP7 projekta, „Transnational Access - TNA“. Jezera veličine 0,08 ha su nasađena sa po 1250 jedinki jednogodišnje mlađi klena. Primenjena su dva tretmana, žute zamke za insekte i sveža biljna biomasa, u triplikatima i dve kontrole. Tokom trajanja eksperimenta, ni u jednom od jezera ribe nisu hranjene dodatnom hranom. Osnovni parametri vode su mereni jednom mesečno. Standardna dužina i masa tela riba je merena na početku i na kraju eksperimenta. Od parametara rasta riba, određivani su prirast, specifična stopa rasta (SGR) i kondicioni faktor (CF). Rezultati su pokazali da nije bilo stastističkih razlika u parametrima kvaliteta vode između tretmana i da su izmerene vrednosti bili u opsegu, koji je karakterističan za prirodna staništa juvenila klena. Na kraju eksperimenta (u oktobru) prosečna masa i dužina tela riba iz različitih tretmana su se značajno razlikovale (p<0.001), sa najvećim vrednostima u tretmanu sa žutim zamkama, osrednjim razlikama u tretmanu sa biljnom masom i najnižim u kontroli (35.78 ± 4.29 g, 29.74 ± 5.12 g, 26.40 ± 3.63 g i 130.7 ± 4.2 mm, 123.5 ± 5.8 mm, 116.8 ± 4.9 mm). Vrednosti prirasta riba su se takođe statistički veoma značajno razlikovale između tretmana (p<0.001), pri čemu je bolji prirast ostvaren u tretmanu sa žutim zamkama u odnosu na biljnu biomasu i kontrolu. Kod specifičnog prirasta riba nisu nađene značajne razlike između tretmana, ali su njihove vrednosti bile značajno veće od kontrole (p<0.001). Međutim, kondicioni faktor (FC) je pokazao statistički značajne više vrednosti u tretmanu sa žutim zamkama i kontroli u odnosu na tretman sa biljnom masom (p<0.005). S obzirom na dobre rezultate u prirastu riba, ova jednostavna, ekonomski isplativa, a ekološki održiva mera za poboljšanje iskoristljivosti prirodnih resursa se može primeniti u gajenju drugih reofilnih vrsta riba. Osim u konzervacione svrhe, ova mera bi mogla naći primenu i u ekstenzivnom i poluintenzivnom sistemu gajenja riba, posebno onih vrsta koje žive u sličnim ambijentalnim uslovima i imaju sličnu ishranu, kao što je šaran i druge omnivorne vrste riba ili pak predatorske ribe koje konzumiraju insekte tokom mlađih životnih stadijuma

Hepatic Rupture as the Initial Presentation of an EGFR-Mutated Lung Adenocarcinoma: A Case Report

Metastatic hepatic rupture; Non-small cell lung carcinoma; Tyrosine kinase inhibitorRuptura hepática metastásica; Carcinoma de pulmón de células no pequeñas; Inhibidor de la tirosina quinasaRuptura hepàtica metastàtica; Carcinoma de pulmó de cèl·lules no petites; Inhibidor de la tirosina quinasaHepatic rupture is a rare complication of solid tumor malignancies, notably in lung adenocarcinomas, and carries an extremely poor overall prognosis. Epidermal growth factor receptor (EGFR) mutations in lung adenocarcinoma predict benefit with tyrosine kinase inhibitors (TKIs). This case report describes a female patient who presented with a metastatic hepatic rupture and was subsequently diagnosed with EGFR-mutated lung adenocarcinoma. The tumor had an impressive response to TKI inhibitor treatment, reversing her extremely poor, short-term prognosis. We believe this unique case sheds light on the treatment management of hepatic ruptures and supports the high response rate seen with TKIs in EGFR-mutated lung cancers, regardless of the patient’s performance status

Women in limnology: From a historical perspective to a present-day evaluation

Research in limnology is nurtured by the work of many fascinating and passionate women, who have contributed enormously to our understanding of inland waters. Female limnologists have promoted and established the bases of our knowledge about inland waters and fostered the need of protecting the values of those ecosystems. However, on numerous occasions, their contribution to the advancement of limnology has not been duly recognized. Here, we review the presence of women in limnology through the history of the discipline: from the pioneers who contributed to the origins to present day' developments. We aim at visibilizing those scientists and establish them as role models. We also analyze in a simple and illustrative way the current situation of women in limnology, the scientific barriers they must deal with, and their future prospects. Multiple aspects fostering the visibility of a scientist, such as their presence in conferences, awards, or representation in societal or editorial boards show a significant gap, with none of those aspects showing a similar visibility of women and men in limnology. This article raises awareness of the obstacles that women in limnology faced and still face, and encourages to embrace models of leadership, scientific management, and assessment of research performance far from those commonly established.info:eu-repo/semantics/publishedVersio

September, 18, 2013, Paphos, Cyprus. http://ceur-ws.org/Vol-1039/The evolution of new technology and its increasing use, has for some years been making the existence of informal learning more and more transparent, especially among young and older adults in both Higher Education and workplace contexts. However, the nature of formal and non-formal, coursebased, approaches to learning has made it hard to accommodate these informal processes satisfactorily. The project aims to facilitate first the identification by the learner (as the last responsible of the learning process), and then the recognition by the institution, in dialogue with the learner, of this learning. To do so a methodology and a technological framework to support it have been implemented. This project has been tested in several contexts showing that an informal learning dialogue between learners and people in charge of the institutions is possible.Tagging, Recognition and Acknowledgment of Informal Learning ExpeRiences project (TRAILER) that is funded by the European Commission's Lifelong Learning Programme.
