A synopsis of Plazia Ruiz & Pav. (Onoserideae, Asteraceae) is presented, including the description of a new species, Plazia robinsonii M.O.Dillon & Sagást., from a locality c. 20 kms west of Huamachuco, Department of La Libertad in northern Peru. It most closely resembles Plazia conferta Ruiz & Pav., a narrow endemic from central Peru some 450 km to the south; however, the latter species has la...

Cereals play a significant role in the Ukrainian economy and agriculture. Viral diseases can cause serious reduction yields. Aim. The aim of work was to identify determine spread grain viruses main cereal-growing regions Ukraine period 2020–2021 using different methods virus detection. Methods. Enzyme-linked immunosorbent assay used commercial test systems by for wheat streak mosaic (WSMV), bar...

BACKGROUND Respiratory muscle unloading during exercise could improve locomotor muscle oxygenation by increasing oxygen delivery (higher cardiac output and/or arterial oxygen content) in patients with chronic obstructive pulmonary disease (COPD). METHODS Sixteen non-hypoxaemic men (forced expiratory volume in 1 s 42.2 (13.9)% predicted) undertook, on different days, two constant work rate (70...

ELISA, cDNA dot blot hybridization and transmission by vector aphids were used to investigate the occurrence and degree of cross-protection produced in oat plants by virus isolates representing five strains or serotypes of barley yellow dwarf virus, namely PAV, MAV, SGV, RPV and RMV. Generally, the degree of cross-protection was positively correlated with the serological relatedness between the...

Recently, we demonstrated that kinesin-1 can slide microtubules against each other, providing the mechanical force required for initial neurite extension in Drosophila neurons. This sliding is only observed in young neurons actively forming neurites and is dramatically downregulated in older neurons. The downregulation is not caused by the global shutdown of kinesin-1, as the ability of kinesin...

Forensic-evaluation systems should output likelihood-ratio values that are well calibrated. If they do not, their will be misleading. Unless a forensic-evaluation system is intrinsically well-calibrated, it calibrated using parsimonious parametric model trained calibration data. The then tested validation Metrics of degree based on the pool-adjacent-violators (PAV) algorithm recalibrate calcula...

Let V⊂Rm be a convex body, symmetric about all coordinate hyperplanes, and let PaV,a≥0, set of algebraic polynomials whose Newton polyhedra are subsets aV. We prove limit equality as a→∞ between the sharp constant in multivariate Markov-Bernstein-Nikolskii type inequalities for from PaV corresponding entire functions exponential with spectrum V.
