This paper focuses on the problem of accurate Fault Characteristic Frequency (FCF) estimation of rolling bearing. Teager-Kaiser Energy Operator (TKEO) demodulation has been applied widely to rolling bearing fault detection. FCF can be extracted from vibration signals, which is pre-treatment by TEKO demodulation method. However, because of strong noise background of fault vibration signal, it is...

N-methyl-3-phenyl-norbornan-2-amine (camfetamine; CFA) is sold as a so-called "research chemical" via the internet and belongs as an amphetamine-type stimulant (ATS) to the group of new psychoactive substances (NPS). CFA is an analogue of N-ethyl-3-phenyl-norbornan-2amine (fencamfamine; FCF), which was developed in the 1960’s as an appetite suppressant and a stimulant for treating depressive da...

BACKGROUND Chronic kidney disease (CKD) is common in geriatric cats, and the most prevalent pathology is chronic tubulointerstitial inflammation and fibrosis. The cell type predominantly responsible for the production of extra-cellular matrix in renal fibrosis is the myofibroblast, and fibroblast to myofibroblast differentiation is probably a crucial event. The cytokine TGF-β1 is reportedly the...

The interaction of Fast Green FCF (FCF) with proteins (including bovine serum albumin (BSA), human serum albumin (HSA), pepsin (Pep) and alpha-chymotrypsin (Chy), and lysozyme (Lys)) was characterized by enhanced resonance light-scattering (RLS) measurements using a common spectrofluorometer. The enhanced RLS signals of FCF by proteins at 279.0 nm were obtained, and the mechanism of the RLS enh...

BACKGROUND No previous studies have investigated whether additional telephone follow-up counseling sessions after face-to-face counseling can increase quitting in China, and whether this strategy is feasible and effective for promoting smoking cessation is still unclear. METHODS A non-randomized controlled study was conducted in Beijing. We compared the quit rates of one group which received ...

OBJECTIVES Smoking cessation services can help smokers to quit; however, many smoking relapse cases occur over time. Initial relapse prevention should play an important role in achieving the goal of long-term smoking cessation. Several studies have focused on the effect of extended telephone support in relapse prevention, but the conclusions remain conflicting. DESIGN AND SETTING From October...

Septins, which are involved in cytokinesis, have been identified in a variety of fungi and animal cells. For analysis of the function of septin, drugs targeting septin would be useful; however, no such drugs have been available hitherto. By serendipity, we found that forchlorfenuron (FCF, N-(2-chloro-4-pyridyl)-N-phenylurea, 4PU300), a synthetic plant cytokinin, disturbed cytokinesis in Sacchar...

Closed, laser-induced optical transitions (“optical cycling transitions”) of molecules can be used for state preparation and measurement in quantum information science sensing. Increasingly complex molecular species supporting provide new capabilities science, it is not clear if there a limit on their size or complexity. We explore Ca–O–L constructs to support the center, Ca, with ligands, L, b...

This study investigates how smallholder farmers attract contracts from agribusiness firms. We focus on firm-cooperative-farmer (FCF) contract farming and examine its potential contribution to the income of rice in Vietnam. found that participation FCF is associated with higher paddy yield, revenue, cultivation, which consistent previous research staple food crops. Furthermore, this model can be...
