objective: the current study was undertaken to examine the bactericide effects of atmospheric plasma produced by flat and comb electrodes on e.coli. materials and methods: dc (20 w) and ac (500 w) power supplies, flat and comb electrodes, insulator and oxygen gas were used to produce atmospheric plasma. bactericide effects of the atmospheric plasma were studied on e.coli on sterilized plate pla...

We prove that if $R$ is a commutative Noetherian ring, then every countably generated flat $R$-module quite flat, i.e., direct summand of transfinite extension localizations in countable multiplicative subsets. also show the spectrum cardinality less than $\kappa$, where $\kappa$ an uncountable regular cardinal, modules with generators. This provides alternative proof fact over ring spectrum, a...

BACKGROUND Tympanometry can indicate middle ear effusion in children referred for tympanostomy tube placement. In outpatient setting, objective adjunctive tools are needed to diagnose the otitis media spectrum. METHODS We enrolled and followed 515 children aged 6-35 months at primary care level. We compared tympanometry with pneumatic otoscopy and evaluated the proportions of type A, C1, C2, ...

This study aims to improve students' understanding of mathematical concepts by applying augmented reality-based flat-sided wake-up cards media at SMP 10 Sungai Kakap. Experimental research with a quantitative approach was chosen as the method in this study. The instrument used description test form pre-test and post-test population 8th graders Kakap, Kabupaten Kubu Raya, West Kalimantan which c...

in this paper, an integration of a symbolic power series method - padé approximation technique (ps - padé), was utilized to solve a system of nonlinear differential equations arising from the similarity solution of laminar thermal boundary layer over a flat plate subjected to a convective surface boundary condition. as both boundary conditions tended to infinity, the combination of series solut...

the falling and settling of solid particles in gases and liquids is a natural phenomenon happens in many industrial processes. this phenomenon has altered pure forced convection to a combination of heat conduction and heat convection in a flow over a plate. in this paper, the coupling of conduction (inside the plate) and forced convection of a non-homogeneous nanofluid flow (over a flat plate) ...

Bacterial shape usually is dictated by the peptidoglycan layer of the cell wall. In this paper, we show that the morphology of the Lyme disease spirochete Borrelia burgdorferi is the result of a complex interaction between the cell cylinder and the internal periplasmic flagella. B. burgdorferi has a bundle of 7-11 helically shaped periplasmic flagella attached at each end of the cell cylinder a...
