The inhibition effect of Vernonia amygdalina (bitter leaf) extract on the corrosion behaviour of embedded mild steel rebar in concrete has been investigated by electrochemical potential measurement, pH and gravimetric (weight loss) methods. The results were further analysed using the two-factor ANOVA test. The experiments were performed using bitter leaf extract as a green inhibitor in 3.5% sod...

The system biologist is currently lacking a general-use method for a gene circuit ‘voltmeter’ or gene system algorithm ‘print statement’. What is needed is a non-destructive, carrier non-modifying, means of testing ‘live’ biological systems at the single-molecule level. A method using the nanopore transduction detector (NTD) is demonstrated for single-molecule characterization in some situation...

1. Electric generation by bacteriochlorophyll reaction center complexes from Rhodospirillum rubrum and by photosystem I complexes from pea chloroplasts has been studied. 2. The methods for the proteoliposome reconstitution from azolectin and bacteriochlorophyll- or plant chlorophyll-containing protein complexes have been elaborated. Light-dependent electric responses of the proteoliposomes were...

The aim of this study is to elucidate the effects of interleukin-6 (IL-6) on the expression and activity of the epithelial sodium channel (ENaC), which is one of the key mechanisms underlying tubular sodium reabsorption. M-1 cortical collecting duct cells were treated with IL-6 (100 ng/ml) for 12 h. Real-time polymerase chain reaction and immunoblotting were employed to examine the mRNA and pro...

1.0 Introduction The use of "microwave holography" as the primary method of evaluating the ALMA antennas and setting their panels has been the project's baseline for several years. There is a long history of such measurements in radio astronomy (e.g., [3-5]). We are particularly drawing on experience at the NRAO in holographic measurements of the 12 M Telescope, 140 Ft Telescope, and VLA antenn...

When a piezoelectric film is glued on the surface of a structure member subjected to mechanical load, a distribution of electric potential is induced. In the existence of defects in the member, a characteristic variation of electric potential is observed. Based on this phenomenon, the passive electric potential CT (computed tomography) method is developed for detecting and identifying defects i...

Background: Complex decongestive therapy (CDT) is one of the most common treatments used in lymphedema. Effects of lymphedema treatment and its predictive factors were studied previously but its impact on quality of life (HRQOL) is still unknown. Objectives: This study, in addition to investigating CDT effects on HRQOL, examined factors that can influence it, to estimate the effect of treatment...

Numerous methods of studying the sensibility of the skin have been reported. Martin (1) described the threshold of faradic break shocks; Ollendorf (2) used hair strokes, pin pricks, heat and pressure with a probe in normal and abnormal skin to determine differences in sensation; Mayr (3) utilized the pressure of a water manometer on normal and syphilitic skin; Hardy and Wolff (4) introduced the...

In this research, after carrying out chemical tests measuring the moisture, protein and ash contents on rice flour according to standard methods, gluten- free breads were prepared from rice flour combined with 0.5% Carboxy Methyl Cellulose (CMC) and 1% -κCarrageenan gum. A sample lacking gum was also produced as control. Rice breads (with gum and without gum) were then produced by semi-industri...
