2018
O trabalho realizado pela equipe de pesquisa multidisciplinar, liderada pela Universitat de Valencia Estudi General (UVEG) e a Universidade Federal do Acre (UFAC), de detalhamento da topografia, em especial na RESEX Chico Mendes, criou progresso significativo no conhecimento das estruturas de terra construídas na paisagem amazônica, conhecidas popularmente como geoglifos, no que se refere a aplicação de topografia de alta precisão para algumas das estruturas, compreensão geral fenômeno e aplicação de uma nova estratégia de pesquisa, com o auxílio de ferramentas como o Google Earth, Google Maps, GPX, OpenStreetMap e Lidar. Ainda há muito trabalho de campo a ser feito na Amazônia Ocidental, n…

Darba mērķis ir izpētīt atvērto datu iegūšanas, apkopošanas un analīzes iespējas lielu pilsētu dzīvojamības novērtēšanai, par piemēru ņemot Rīgas pilsētu. Darba rezultātā tiks izveidots interaktīvs rīks, kas ļautu katram interesentam norādīt tieši sev svarīgākos dzīvesvietas izvēles kritērijus, un atrast piemērotāko vietu, kas tiem atbilst. Darba rezultātā tika izveidots minētais rīks, kā arī izveidota heterogēna datu ievākšanas un apstrādes platforma no tādiem datu avotiem kā OpenStreetMap, ss.lv u.c. Tika izveidots algoritms šo datu ātrai apvienošanai, kā arī interaktīva karte šo datu attēlošanai.
Metazoan parasite communities and diet of the velvet belly lantern shark Etmopterus spinax (Squaliformes: Etmopteridae): a comparison of two deep-sea…
2014
By combining an examination of stomach contents yielding a snapshot of the most recent trophic niche and the structure of parasite communities reflecting a long-term feeding niche, this study aimed at gaining more comprehensive information on the role of the small-sized deep-water velvet belly lantern shark Etmopterus spinax in the local food webs of the Galicia Bank and the canyon and valley system of the Aviles Canyon, which have been both proposed for inclusion in the Natura 2000 network of protected areas. As far as is known, this study provides the first comparative parasite infracommunity data for a deep-sea shark species. Component parasite communities in E. spinax were relatively ri…
Francesco Solano dhe studimet arbëreshe gjatë gjysmës së dytë të shek. XX
2020
Francesco Solano është një nga autorët dhe studiuesit kryesorë arbëreshë të gjysmës së dytë të shek. XX, vepra e të cilit ushtroi një ndikim vendimtar në zhvillimet e mëtejshme të albanologjisë në Itali. Kjo kumtesë synon të vërë në pah dhe të sintetizojë karakteristikat kryesore të kontributit të shumëfishtë të Solanos në lëmenjtë e dialektologjisë arbëreshe, të filologjisë, të letërsisë arbëreshe dhe të mësimdhëniessë shqipes në mjedisin arbëresh. Francesco Solano è stato un eminente studioso italo-albanese della seconda metà del XX sec., la cui opera esercitò un influsso decisivo sugli sviluppi ulteriori dell'albanologia in Italia. L'articolo intende evidenziare e sintetizzare le caratte…
Myoglobin on Silica: A Case Study of the Impact of Adsorption on Protein Structure and Dynamics
2013
International audience; If protein structure and function changes upon adsorption are well documented, modification of adsorbed protein dynamics remains a blind spot, despite its importance in biological processes. The adsorption of metmyoglobin on a silica surface was studied by isotherm measurements, microcalorimetry, circular dichroïsm, and UV-visible spectroscopy to determine the thermodynamic parameters of protein adsorption and consequent structure modifications. The mean square displacement and the vibrational densities of states of the adsorbed protein were measured by elastic and inelastic neutron scattering experiments. A decrease of protein flexibility and depletion in low freque…
IC3D Classification of Corneal Dystrophies—Edition 2
2015
To update the 2008 International Classification of Corneal Dystrophies (IC3D) incorporating new clinical, histopathologic, and genetic information.The IC3D reviewed worldwide peer-reviewed articles for new information on corneal dystrophies published between 2008 and 2014. Using this information, corneal dystrophy templates and anatomic classification were updated. New clinical, histopathologic, and confocal photographs were added.On the basis of revisiting the cellular origin of corneal dystrophy, a modified anatomic classification is proposed consisting of (1) epithelial and subepithelial dystrophies, (2) epithelial-stromal TGFBI dystrophies, (3) stromal dystrophies, and (4) endothelial d…
Imbalance between genomic gain and loss identifies high-risk neuroblastoma patients with worse outcomes
2021
Survival in high-risk neuroblastoma (HR-NB) patients remains poor despite multimodal treatment. We aimed to identify HR-NB patients with worse outcomes by analyzing the genomic instability derived from segmental chromosomal aberrations. We calculated 3 genomic instability indexes for primary tumor SNP array profiles from 127 HR-NB patients: (1) Copy number aberration burden (%gainslength+%losseslength), (2) copy number load (CNL) (%gainslength-%losseslength) and (3) net genomic load (NGL) (%gainsamount-%lossesamount). Tumors were classified according to positive or negative CNL and NGL genomic subtypes. The impact of the genomic instability indexes on overall survival (OS) was assessed with…
Structural factors controlling ligand binding to myoglobin: a kinetic hole-burning study.
1998
Using temperature-derivative spectroscopy in the temperature range below 100 K, we have studied the dependence of the Soret band on the recombination barrier in sperm whale carbonmonoxy myoglobin (MbCO) after photodissociation at 12 K. The spectra were separated into contributions from the photodissociated species, Mb*CO, and CO-bound myoglobin. The line shapes of the Soret bands of both photolyzed and liganded myoglobin were analyzed with a model that takes into account the homogeneous bandwidth, coupling of the electronic transition to vibrational modes, and static conformational heterogeneity. The analysis yields correlations between the activation enthalpy for rebinding and the model p…
An unambiguous procedure for discovering relaxation influence on M�ssbauer spectra
1994
A mathematical procedure which gives an opportunity to distinguish between relaxation and distribution mechanisms of the Mossbauer line broadening is proposed. It is based on the method of Mossbauer line sharpening developed recently [1] and allows one to answer unambiguously the question whether or not relaxation manifests itself in Mossbauer measurements by examining the wings of the spectrum. The procedure is applied to the spectra of high spin ferric metmyoglobin and (Fe0.65Ni0.35)1−xMnx alloys. Analysis of the metmyoglobin spectra manifests the presence of the relaxation influence in the temperature range 10 K≦T≦100 K. Analysis of the alloy spectra shows that for the temperatures 4 K≦T…
Rayleigh scattering of Mössbauer radiation on a myoglobin single crystal
1992
The RSMR technique was used to determine the fraction of radiation which is scattered elastically and inelastically, respectively, into Bragg reflections of a metmyoglobin single crystal. From this measurement 〈x2 1c〉=0.027±0.008 A2 has been determined which is due to long range correlated motions in analogy to acoustic and optic modes in solids.
