: Three different approaches for improvement of objective video quality evaluation are presented in this paper. Improvement is obtained through quality guided temporal pooling, information content weighted temporal pooling, and multiscale analysis. The analysis was performed using five objective video quality assessment measures on two publicly available datasets with subjective quality scores. Only the videos with H.264, H.265, and MPEG-2 types of compression from two datasets were considered. The level of agreement between the subjective and objective quality scores are given through the Spearman rank-order correlation coefficients on complete datasets and subsets of video sequences with the same type of compression. Obtained results show that the performance of objective measures is dependent on the choice of the dataset. The greatest improvement is given by multiscale analysis.

Rad se bavi počecima znanstvenog promišljanja hrvatske književnosti u Bosni i Hercegovini te predstavlja biografska i biobibliografska istraživanja sedmorice autora, počevši od Filipa Lastrića u 18. do Tugomira Alaupovića u prvoj polovici 20. stoljeća. Promatramo kako su ovi autori razumijevali književnost i njezinu povijesnu dimenziju, osobito kako su pristupili osnovnim problemima povijesti književnosti kao što su definiranje korpusa, izbor pisaca, periodizacija, književnopovijesna interpretacija i vrednovanje te koja su rješenja ponudili. Analizira se i postupno napuštanje okvira biobibliografije te primjena složenijih književnopovijesnih pristupa.

As plantas necessitam de elementos essenciais para sua vida, devido as diversas funcoes que esses elementos desempenham.  descrever e avaliar os sintomas de carencia nutricional de macronutrientes em abobrinhaa italiana, atraves do diagnostico visual e avaliar os parâmetros de crescimento. O delineamento estatistico utilizado foi o DIC com tres repeticoes, contendo 7 tratamentos, em solucao nutritiva. Os tratamentos foram: solucao nutritiva completa (controle), solucoes nutritivas com omissoes individuais de N, P, K, Ca, Mg e S. Apos germinadas, as mudas foram translocas para a solucao nutritiva completa, com 10% da sua forca ionica (periodo de adaptacao), as quais permaneceram sob aeracao constante. Posteriormente, foram transplantadas em vasos de plastico (8L) com solucao nutritiva. Os sintomas percebidos, foram fotografados e descritos. Apos a manifestacao dos sintomas visuais de deficiencia, as plantas dos tratamentos foram colhidos. A omissao dos nutrientes N, P, K, Ca e Mg em solucao nutritiva resultam em alteracoes morfologicas, traduzidas em sintomas caracteristicos de deficiencia de cada nutriente. A omissao de macronutrientes afeta os parâmetros de crescimento e producao de materia seca de Abobrinha italiana. De maneira em geral, a omissao de macronutrientes que mais afeta as diferentes partes a plantas foram N e P.

Objective: To evaluate the casuistry of vascular malformations in our division and to analyze the predominant clinical findings of these malformations. Methods: A survey was carried out searching for all cases of pulmonary vascular malformations diagnosed, from August 1986 to December 2003. Through the analysis of the medical records of these patients, the following variables were evaluated: structural pulmonary alteration, clinical presentation, mean age at diagnosis, gender and clinical evolution. Results: The pathologies found were: pulmonary sequestration 6 cases (25%), agenesis and / or pulmonary hypoplasia 7 cases (30%), arteriovenous fistulas 4 cases (16%), vascular ring 6 cases (25%) and pulmonary valve agenesis 1 case (4%). Nine patients were male and 13 were female. Age at diagnosis ranged from 1 month to 58 years. The symptoms varied according to the pathology. The most frequent were recurrent respiratory infection, stridor, cyanosis, dyspnea. Of the 22 patients studied, 11 (50%) cases were amenable to surgical correction. Conclusion: Pulmonary vascular malformations are rare pathologies, but pediatricians should keep them in mind to obtain an early diagnosis, correct propaedeutics and, if possible, surgical correction of these pathologies.
