The sequencing of the complete genome of a Tomato black ring virus (TBRV) and of the RNA2 of three Grapevine chrome mosaic virus (GCMV) isolates from…
2014
The complete genome of a Tomato black ring virus isolate (TBRV-Mirs) (RNA1, 7,366 nt and RNA2, 4,640 nt) and the RNA2 sequences (4,437; 4,445; and 4,442 nts) of three Grapevine chrome mosaic virus isolates (GCMV-H6, -H15, and -H27) were determined. All RNAs contained a single open reading frame encoding polyproteins of 254 kDa (p1) and 149 kDa (p2) for TBRV-Mirs RNA1 and RNA2, respectively, and 146 kDa for GCMV RNA2. p1 of TBRV-Mirs showed the highest identity with TBRV-MJ (94 %), Beet ringspot virus (BRSV, 82 %), and Grapevine Anatolian ringspot virus (GARSV, 66 %), while p2 showed the highest identity with TBRV isolates MJ (89 %) and ED (85 %), followed by BRSV (65 %), GCMV (58 %), and GA…
Improved acid tolerance of a recombinant strain of Escherichia coli expressing genes from the acidophilic bacterium Oenococcus oeni.
2001
Aims:Oenococcus oeni is a lactic acid bacterium used in wine fermentation. Two open reading frames (orfB and orfC) were identified in the upstream region of the hsp18 gene, encoding the small heat-shock protein Lo18. Expression of these genes in conditions of acid stress was studied in Escherichia coli. Methods and Results: Sequence analysis showed that orfB encodes a putative transcriptional regulator of the LysR family. The protein encoded by orfC shares homologies with multi-drug resistance systems. Heterologous expression of orfB, orfC and hsp18 genes in Escherichia coli significantly enhanced the viability of the host strain under acidic conditions. Conclusions: It was demonstrated tha…
Genetic organization of the mle locus and identification of a mleR-like gene from Leuconostoc oenos
1996
Characterization of the mle locus harboring the malolactic enzyme gene mleA and malate permease gene mleP from Leuconostoc oenos was completed in this study by mRNA analysis. Northern (RNA) blot experiments revealed a 2.6-kb transcript, suggesting an operon structure harboring mleA and mleP genes. Primer extension analysis showed that the mle operon has a single transcription start site located 17 nucleotides upstream of the ATG translation start site for the mleA gene. We found sequences, TTGACT and TATGAT (which are separated by 18 bp), that are closely related to the gram-positive and Escherichia coli consensus promoter sequences. Upstream of the mleA gene, an 894-bp open reading frame t…
A Survey of Methods to Interpolate, Distribute and Extra- polate Time Series
2010
This survey provides an overview with a broad coverage of the literature on methods for temporal disaggregation and benchmarking. Dozens of methods, procedures and algorithms have been proposed in the statistical and economic literature to solve the problem of transforming a low-frequency series into a high-frequency one. This paper classifies and reviews the procedures, provides interesting discussion on the history of the methodological development in this literature and permits to identify the assets and drawbacks of each method, to comprehend the current state of art on the subject and to identify the topics in need of further development. It would be useful for readers who are interest…
Do serifs provide an advantage in the recognition of written words?
2011
A neglected issue in the literature on visual-word recognition is the careful examination of parameters such as font, size, or interletter/interword spacing on reading times. Here we analysed whether serifs (i.e., the small features at the end of strokes) play a role in lexical access. Traditionally, serif fonts have been considered easier to read than sans serif fonts, but prior empirical evidence is scarce and inconclusive. Here we conducted a lexical decision experiment (i.e., a word/nonword discrimination task) in which we compared words from the same family (Lucida) either with a serif font or with a sans serif font—in both a block list and a mixed list. Results showed a small, but sig…
MODERN VOLLEYBALL ANALYSIS AND TRAINING PERIODIZATION
2018
The purpose of this study is to clarify the scientific approach to modern volleyball at men´s high-level and introduce the most influential studies, which still are not very well implemented in the world of volleyball. On individual level, requirements of modern volleyball consist psychological aspects like inner motivational and maintaining the focus during the game, which is difficult because there are a lot of breaks and successful and unsuccessful rallies in every volleyball match. Inner motivated player can push himself easier to the limits of his capacity during the game. Good focus and team routines keep the difference between won and lost rally small so that the player and the team …
Mobile solution for better reading instruction in rural Africa
2015
GraphoGame Teacher Training Service is a mobile-based solution for providing teachers with scientifically validated pedagogical training in literacy instruction. In many African countries teachers currently have insufficient knowledge to teach literacy in local languages and learning materials are scarce, especially for children with learning difficulties. As part of the GraphoWorld network, CAPOLSA/University of Zambia is developing new mobile-based method for providing in-service training for teachers in literacy instruction and assisting children with learning difficulties. GraphoGame Teacher Training Service was piloted in October 2014 in rural Zambia. An orientative workshop was given …
The use and beauty of ultra-high-resolution seismic reflection imaging in Late Quaternary marine volcaniclastic settings, Napoli Bay, Italy
2019
A Nápolyi-öbölben felvett ultra nagy felbontású egycsatornás (IKB-Seistec™) reflexiós szeizmikus szelvények korábbi geológiai és geofizikai vizsgálatok eredményeivel együtt kivételes, eddig soha nem látott felbontású szeizmikus leképezését nyújtják a Flegrei-mezők és a Somma-Vezúv felszín alá süllyedt késő-pleisztocén–holocén rétegtani felépí - tésének. A szeizmikus szelvényeken látott geometria és gravitációs magvevővel nyert üledékek adatainak összevetéséből Campania partközeli kontinentális talapzatán számos olyan üledékes és vulkáni szerkezet, valamint hidrotermális jelenség került leképezésre, melyek a legutolsó glaciális maximum (kb. 18 000 év) óta keletkeztek. A Pozzuoli-öbölben mért…
Performance of LoRa technology: link-level and cell-level performance
2020
Abstract LoRa is a chirp spread spectrum technology that is becoming very popular for low-power wide-area networks, with high-density devices. In this chapter, we study the capacity of LoRa in rejecting different interfering signals. First, we analyze LoRa modulation numerically demonstrating that channel captures appear easily and that collisions between packets modulated with different spreading factors (SFs) are not uncommon. We validate such findings in experiments based on commercial devices and software-defined radios. Second, we model the network capacity obtainable in a typical LoRa cell: we show that high SFs can be seriously influenced by inter-SF collisions and that fading has a …
Alcune figure della diserzione nell'opera di Pavese
2022
Deserting Characters in Pavese’s Work ∙ Pavese’s experience of World War ii has been widely controversial. Anti-fascist without joining the Italian Resistance, Pavese reimagines his nonparticipation to the confict across several of his post-1945 works. The essay ofers a thematic reading on deserting fgures in some poems from La terra e la morte, in I due (included in Dialogues with Leucò), in the novel The House on the Hill. The reading brings out the torn and evolving development of the issue of deserting in Pavese’s oeuvre.
