Edaphyc characteristics and floristic composition of the seasonally dry forest la menta and timbes, Piura Region, Peru
2011
Con el objetivo de contribuir al conocimiento de los ecosistemas naturales del país, se determinó las características edáficas y la composición florística del bosque estacionalmente seco (La Menta, 04º 43' 55" LS y 80º 04' 55" LO, provincia de Piura y Timbes, 04º 44' 58" LS y 80º 03' 33" LO, provincia de Ayabaca), ambos en la región Piura, Perú. El área de estudio abarcó una extensión aproximada de 6 000 hectáreas en un rango altitudinal entre 350 m a 1 350 m. En cada bosque se muestrearon 5 transectos de 10 x 50 m a intervalos de 20 m, sumando un total de 2 500 m². El análisis de suelo reveló niveles bajos de materia orgánica, nitrógeno y potasio y medios de fósforo asimilable. Estos suelo…
Toward evidence-based severity assessment in rat models with repeated seizures: II. Chemical post-status epilepticus model.
2019
Objective: Considering the complexity of neuronal circuits and their epilepsy-associated alterations, epilepsy models cannot be completely replaced by in vitro experimental approaches. Decisions about ethical approval of in vivo studies require a thorough weighing of the animal's burden and the benefit regarding the expected gain in knowledge. Methods: Based on combined behavioral, biochemical, and physiological analyses, we assessed the impact on animal well-being and condition in different phases of the pilocarpine post–status epilepticus (SE) model in rats. Results: As a consequence of SE, increased levels of impairment were evident in the early postinsult phase and late chronic phase, w…
Latvijas Universitātes Bibliotēka (1958-1990) preses izdevumu publikācijās
2021
Bakalaura darba tēma ir “Latvijas Universitātes Bibliotēka (1958–1990) preses izdevumu publikācijās”. Tā mērķis ir sastādīt bibliogrāfisko rādītāju par Latvijas Universitātes Bibliotēku laika posmā no 1958. līdz 1990. gadam un veikt rakstu satura analīzi. Par Latvijas Universitātes Bibliotēku periodisko izdevumu publikācijās, par konkrēto laika posmu, līdz šim bibliogrāfiskais rādītājs nav izveidots. Tā esamība un aptvērums ir svarīgs, jo pēc rādītāja analīzes iespējams redzēt, kā tika veidota sociālā realitāte par Latvijas Universitātes Bibliotēkas darbību trimdas laikrakstos un Padomju Latvijas presē. Bakalaura darbs balstīts uz rāmēšanas un hermeneitikas teoriju. Publikāciju analīze veik…
Latvijas Universitātes zinātnieku publikācijas un citējamība pedagoģijas nozarē
2022
Bakalaura darba tēma ir “Latvijas Universitātes zinātnieku publikācijas un citējamība pedagoģijas nozarē”. Mērķis ir noskaidrot Latvijas Universitātes zinātnieku publikāciju skaitu un citējamību pedagoģijas nozarē citējamības datubāzēs Scopus un Web of Science un salīdzināt ar pārējo Baltijas valstu zinātnieku sniegumu pedagoģijas nozarē. Teorētisko bāzi veido bibliometrijas teorija. Pētījuma laikā gūtie rezultāti norāda, ka pēc indeksēto zinātnisko publikāciju skaita LU ir konkurētspējīga ar citām Latvijas zinātniskajām institūcijām, bet nav konkurētspējīga ar Baltijas valstu ietekmīgākajām zinātniskajām institūcijām.
NEW APPLICATIONS IN THE USE OF CELLULOSE PULP FOR THE INTEGRATION OF WOODEN SUPPORTS
2017
Cellulose pulp, mainly utilized as a support for cleaning stone material, in this study, is proposed as a filler for wooden supports. In the last 10 years, pulp has been used in many restoration works carried out in the laboratory of the Diocesan Museum (MDP) in Palermo, including both wooden sculptures and panel paintings. These artworks, exhibited in the MDP, are constantly monitored in order to evaluate the effectiveness of cellulose pulp as a filler, assessing its durability and bio-receptivity. In particular, structural characteristics, drying time, shrinkage, loss in weight, affinity to the pigments, etc., were simultaneously evaluated. Tests were also carried out on artificially aged…
Phylogeny of snapdragon species (Antirrhinum; Scrophulariaceae) using non-coding cpDNA sequences
2005
Antirrhinum is an Old World genus of up to 25 perennial taxa, mainly located in the western Mediterranean basin. A molecular analysis of 24 taxa of Antirrhinum was undertaken using cpDNA sequences from the trnT (UGU)-trnL (UAA) 5' exon region. The Kimura two-parameter model was chosen to calculate pairwise nucleotide divergence values between cpDNA sequences, and a bootstrapped neighbor-joining dendrogram was constructed from the nucleotide divergence distance matrix. Eighteen sites were variable across the studied samples and the position of 7 indels, ranging from 1 to 7 bp, was inferred from the sequence alignment. Several trnT-trnL sequences are identical in: some members of subsection K…
A validated bioenergetics model for ruffeGymnocephalus cernuusand its application to a northern lake
2008
A bioenergetics model was constructed for ruffe Gymnocephalus cernuus, and the model was used to estimate the food consumption of a native G. cernuus stock in Pyhajarvi, a large mesotrophic lake in south-west Finland. The parameters for the bioenergetics model were determined through laboratory experiments conducted at several temperatures between 5 and 22° C for different sized G. cernuus (from 6 to 27 g). The model was verified and validated with independent laboratory growth experiments. The validated model was applied to field data from Pyhajarvi to estimate the food consumption of G. cernuus and its effects on the zoobenthos community during the years 2002–2004. The total annual food c…
Different trends of neighboring populations of Lesser Kestrel: Effects of climate and other environmental conditions
2019
The sensitivity of population trends to the climate and environment is generally considered a species-specific trait. However, evidence that populations may show different responses to the climate and environmental conditions is growing. Whether this differential sensitivity may arise even among neighboring populations remains elusive. We compared the trends of two neighboring populations of the Lesser Kestrel Falco naumanni, using data from a 12-year survey of 158 colonies in Sicily, Italy; the two populations inhabiting a lowland and an highland area, respectively. Population trends were modeled through the TRIM algorithms implemented in R (package rtrim). A reversed U-shaped population t…
Retrieving and broadcasting near-real-time biophysical parameters from MODIS and SEVIRI receiving stations at the global change unit of the Universit…
2015
We present here the automatic processing chains implemented at the Global Change Unit of the University of Valencia. These allow for a near-real-time retrieval of various biophysical parameters from both Sun-synchronous TERRA/AQUA Moderate Resolution Imaging Spectroradiometer MODIS and geostationary Meteosat Second Generation Spinning Enhanced Visible and Infrared Imager MSG SEVIRI sensors. Retrieved parameters, namely sea and land surface temperatures SST and LST, respectively, normalized difference vegetation index NDVI, and vegetation condition index VCI, are similar for both sensors, and specific approaches have been developed and implemented for near-real-time parameter retrievals: htt…
