Tomato golden mosaic virus is a bipartite geminivirus whose genome is divided between two circular DNA molecules. DNA A encodes functions necessary for viral DNA replication and encapsidation, whereas DNA B provides functions needed for movement in the host. Previous studies have shown that the viral AL2 gene product transactivates expression of the coat protein gene (AR1). We have investigated...

Paleoclimatic time series are often unevenly spaced in time, making it difficult to obtain an accurate estimate of their red-noise spectrum. A Fortran 90 program (REDFIT) is presented that overcomes this problem by fitting a first-order autoregressive (AR1) process, being characteristic for many climatic processes, directly to unevenly spaced time series. Hence, interpolation in the time domain...

Three dye molecules (Dye) of Acid Brilliant Scarlet 3R (AR18), Amido Naphthol Red G (AR1), Indigo Carmine (IC), as well sodium dodecyl sulfate (SDS) dopant agents were used for electrochemical synthesis polypyrrole (PPy) layers onto indium doped tin oxide (ITO) coated polyethylene terephthalate (PET) electrode. The morphology, electrochemical, optical, and spectroelectrochemical properties the ...

OBJECTIVES To investigate quinolone resistance mechanisms in an Escherichia coli clinical isolate (Ar2) resistant to ofloxacin but susceptible to nalidixic acid selected after 10 days of ofloxacin therapy in a patient with prostatitis. METHODS Molecular typing (ERIC-PCR and RAPD), antibiotic susceptibility and gyrA, gyrB, parC and parE QRDR sequences were compared for E. coli Ar2 and a wild-t...

The effects of strain on the microstructure and mechanical properties 0.81C-0.22Si-0.31Mn (wt%) high-carbon steel were investigated by thermal simulation, scanning electron microscopy, high-resolution transmission microscopy (HRTEM), an backscatter diffractometer (EBSD). It was found that when deformed at 670 °C (a temperature between A1 Ar1), a deformation-induced pearlite transformation cemen...

We prove a conjecture of Nakajima describing the relation between the geometry of quiver varieties of type A and the geometry of the partial flags varieties and of the nilpotent variety. The kind of quiver varieties we are interested in, have been introduced by Nakajima as a generalization of the description of the moduli space of anti-self-dual connections on ALE spaces constructed by Kronehei...

Time series techniques are applied to Ghara-Aghaj flow records, in order to generate forecast values of the mean monthly river flows. The study of data and its correlogram shows the effect of seasonality and provide no evidence of trend. The autoregressive models of order one and two (AR1, AR2), moving average model of order one and ARMA (1,1) model are fitted to the stationary series, where th...
