The document analyzes the effect of chemical composition on the curing and properties of UV-cured resins made from urethane diacrylate oligomer, N-vinyl pyrrolidone (NVP) monomer, and trimethylolpropane triacrylate (TMPTA) monomer. Mixture experimental design was used to study 10 sample compositions. Key findings:
1) NVP is more effective than TMPTA at reducing viscosity and increasing depth of cure and heat of reaction.
2) TMPTA is more effective at increasing properties like Young's modulus, tensile strength, and thermal stability.
3) The urethane acrylate system exhibits
Este documento describe el procedimiento de molienda realizado en un molino para una muestra de caolín. Se detallan los pasos de tamizado de la alimentación y el producto, la molienda con diferentes configuraciones del molino, y cálculos de parámetros como la velocidad crítica, diámetro de bolas, y consumo de energía. El objetivo es justificar la eficiencia de la molienda mediante el tamaño de partícula del producto final.

It is Sunday for Andrew Tsvetkov who wakes up at 7:00 am, eats sandwiches and drinks tea or milk before doing homework. He then spends his day going to the waterpark, a shopping center called RIO, and a cafe where he plays computer games and talks with his brother, as well as playing with his cat Varvara, before eating dinner at 8:00 pm and going to sleep at 10:00 pm.
This document discusses challenges with a data science project including the experimental and unpredictable nature, difficulties with scheduling due to unknown completion times, proposing new products with data and technology limitations, and addressing failures by breaking the work into smaller pieces with increased visibility and producing functional interim results to stay on track.
James Paton has over 40 years of experience in steel fabrication, construction, and offshore oil and gas projects. He has worked for numerous companies including Amec Foster Wheeler, Wood Group, and PSN. His roles have involved steelwork installation, pipe support fabrication, and maintenance and modification work on various offshore oil platforms. He has extensive safety training and experience working as a Performing Authority.

This document describes an online university for parents called BabyStep.tv that provides short, expert-created video tips on parenting topics like child development, routines, skills and behaviors. The videos are available through their website and mobile apps in 12 languages. The target market is parents in China, where the mother and baby products market is large and the one-child policy was recently relaxed. The university seeks partners to help distribute their video content and sell paid subscriptions to their parenting advice and tips.
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms.
Kexuema is a mobile app that provides medical information and live chat with doctors to pregnant women in China. It aims to improve health and save lives by empowering women with knowledge during their pregnancies. The app has gained popularity with over 45,000 downloads in its first few months. It addresses the lack of access to reliable healthcare information in China and the shortage of obstetric doctors at many hospitals. The app is backed by an experienced team and board of experts in maternal and child health.
