As regulators of gene expression in multicellular organisms, microRNAs (miRNAs) are crucial for growth and development. While a plethora of factors involved in their biogenesis and action in Arabidopsis thaliana have been described, these processes and their fine-tuning are not fully understood in plants. Here, we used plants expressing an artificial miRNA target mimic (MIM) to screen for negat...

A large body size may differentially influence risk of colorectal cancer (CRC) by anatomic location. The Netherlands Cohort Study includes 120,852 men and women aged 55–69 years who self-reported weight, height, and trouser/skirt size at baseline (1986), as well as weight at age 20 years. Derived variables included body mass index (BMI; weight (kg)/height (m)), BMI at age 20 years, and BMI chan...

Abstract. We present a reliable and robust open dynamic chamber for measuring greenhouse gas exchange in peatlands with minimal disturbance of the ground. This chamber, called “skirt chamber”, is based on transparent plastic film placed above an frame made sparse interwoven wires expanded around base below steel chain that ensures contact to ground, avoiding damage, trenching, cutting vegetatio...

Variation elliptical piston skirt has better mechanical and thermodynamic properties and it is widely applied in internal combustion engine in recent years. Because of its complex form, its geometrical precision evaluation is a difficult problem. In this paper, quasi-particle swarm optimization QPSO is proposed to calculate the minimum zone error and ellipticity of crosssection linear profile, ...

Internal combustion engine research predominantly focuses on routes to lower emissions meet various emission legislation. Lower can be achieved with increased fuel efficiency and less lubricant throw off/lubricant in the piston ring zone. These are all dependent oil film that forms between liner components. This article details use of ultrasonic sensors study thickness rings/skirt a fired diese...
