Ispitivanje osobina ličnosti nastavnika i profesionalnih karakteristika uvek je bila aktuelna tema. U radu ćemo pokušati da odgovorimo na istraživačko pitanje: kakvog učenici žele? Ispitivanjem stavova učenika težimo otvorimo školu za njihove potrebe interesovanja, odnosno kroz ovo istraživanje ukažemo značaj uloge u obrazovno-vaspitnom radu. Društvene promene obrazovni trendovi uslovljavaju se...

Hydrocarbonoclastic bacterial communities inhabiting mangrove sediments were characterized by combining molecular and culture-dependent approaches. Surface sediments were collected at two sampling sites in Guanabara Bay (Rio de Janeiro, Brazil) and used to inoculate in vitro enrichment cultures containing crude oil to obtain hydrocarbonoclastic bacterial consortia. In parallel, in situ mesocosm...

In the present study, the ecological distribution of marine Actinobacteria isolated from seamount and non-seamount stations in the Tyrrhenian Sea was investigated. A collection of 110 isolates was analyzed by Automated Ribosomal Intergenic Spacer Analysis (ARISA) and 16S rRNA gene sequencing of representatives for each ARISA haplotype (n=49). Phylogenetic analysis of 16S rRNA sequences showed a...

A novel actinomycete, strain OFN S31(T), was isolated from a complex biofilm in the Altamira Cave, Spain. A polyphasic study was carried out to clarify the taxonomic position of this strain. Phylogenetic analysis with 16S rRNA gene sequences of representatives of the genera Corynebacterium, Dietzia, Gordonia, Millisia, Mycobacterium, Nocardia, Rhodococcus, Segniliparus, Skermania, Tsukamurella ...

Marine-derived Actinobacteria are a source of a broad variety of secondary metabolites with diverse biological activities, such as antibiotics and antitumorals; many of which have been developed for clinical use. Rare Actinobacteria represent an untapped source of new bioactive compounds that have been scarcely recognized. In this study, rare Actinobacteria from marine sediments were isolated f...

Introducción: El uso de los hidrocarburos y sus derivados, han generado un problema contaminación ambiental. Los estudios más actuales sugieren una solución a esta situación, basada en la degradación microbiológica o biotransformación, usando cultivos microbianos axénico. Objetivo: Desarrollar mapeo sistemático literatura científica sobre las investigaciones, acerca bacterias hongos biodegradac...

Long-term coal mining has created unique microbial communities in deep mines. Revealing the community structure and metabolic functions underground environment can contribute to a better understanding of mine ecosystem. In this study, we collected sediment samples from producing mines eastern China at depths −400 −1100 m performed high-throughput sequencing. Results showed that most genera degr...

The detection of image motion is important to vision. Direction-selective retinal ganglion cells (DS-RGCs) respond strongly to stimuli moving in one direction of motion and are strongly inhibited by stimuli moving in the opposite direction. In this article, we investigated the distributions of kainate glutamate receptor subtypes KA1 and KA2 on the dendritic arbors of DS-RGCs in developing (5, 1...
