Abstract Paper-based microfluidics devices can create a new healthcare model. Cellulose is carbohydrate polymer biocompatible and hydrophilic. These characteristics enhance the development of user- friendly diagnostic devices, but the link between paper manufacturing process and performance of the devices is still unclear. Previous studies focused on either commercial papers or lab papers from wood-cellulose fibers, with different basis-weight. This work introduces the effect of refining process and lab paper from non-wood-cellulose fibers, focusing on sisal fibers to overcome the aforementioned challenge. Structural characteristics of paper, such as basis-weight and degree of refining, are optimized and correlated with blood typing test resolution. Unrefined sisal paper of 50 g/m2 and 100 g/m2 basis-weight exhibit a higher gray intensity level than refined paper, and also maximal capillary rise and a pore size suitable for blood grouping tests. Two different blood types were evaluated with results consistent with the traditional methods, testifying the usefulness of this methodology. -
Nanofibrillated Cellulose Applied As Reinforcement for Short-Fiber Paper

Este trabalho teve como objetivo avaliar a influência da adição de diferentes porcentagens de celulose nanofibrilada sobre as propriedades mecânicas e físicas do papel feito a partir da polpa de fibras curtas. A celulose nanofibrilada foi obtida a partir de polpa Kraft de Eucalyptus sp. branqueada, submetida a três diferentes passes no moinho: 2, 10 e 20 passes. Os papéis foram produzidos com a adição de celulose nanofibrilada nas porcentagens de 3, 6 e 9%. Os resultados mostraram que a adição de celulose nanofibrilada aumentou as propriedades mecânicas: índice de tração, índice de arrebentamento e índice de rasgo. A porosidade e a densidade aparente diminuíram. A adição de 9% de celulose nanofibrilada, obtida a partir de 2 passes, proporcionou os melhores resultados com aumento da resistência à tração, arrebentamento e rasgo de 111, 114 e 70%, respectivamente, em comparação aos papéis normais. A melhoria das propriedades mecânicas do papel está relacionada à rede muito densa de ligações de hidrogênio, resultando em maior área de superfície obtida após a desfibrilação. -

The Reference Measurements of the Paper Laboratory
Saimaa University of Applied Sciences Technology Imatra Degree Programme in Paper Technology Petri Penttinen THE REFERENCE MEASUREMENTS OF THE PAPER LABORATORY Thesis 2012 ABSTRACT Petri Penttinen The Reference Measurements of the Paper Laboratory, 55 pages, 9 appen- dices Saimaa University of Applied Sciences, Imatra Unit of technology, Degree Programme in Paper Technology Bachelor’s Thesis 2012 Supervisor: Lecturer Esko Lahdenperä The purpose of this bachelor’s thesis was to create a basis for reference meas- urements of papers and boards used in the paper laboratory of Saimaa Univer- sity of Applied Sciences in Imatra. Testing was focused to the most common physical properties of paper and board. The aim for the reference measure- ments was to setup a database of product properties. This database is later used as reference material when new properties of other products are meas- ured. In the theory part of the work is introduced the laboratory environment, quality systems, and the physical properties of the papers and boards that are meas- ured. Also the test methods of these properties are explained. As the reliability of the testing is very important, in this work is also thought about the things that may cause uncertainty and errors to the results. In the experimental part of the work is performed the basic- and strength prop- erties of the specific papers and boards that were selected. The samples used consist of the paper and board grades manufactured in Stora Enso Imatra and M-real Simpele mills, and of the own samples made of birch, eucalyptus, pine and spruce pulps. These industrial manufactured paper and board types are commonly used with the student works and they can be found from the paper laboratory. -
Paper, Paperboard and Wood Pulp Markets, 2010-2011 Chapter 8
UNECE/FAO Forest Products Annual Market Review, 2010-2011 __________________________________________________________ 71 8 Paper, paperboard and woodpulp markets, 2010-2011 Lead Author, Peter Ince Contributing Authors, Eduard Akim, Bernard Lombard, Tomas Parik and Anastasia Tolmatsova Highlights • Paper and paperboard output rebounded along with overall industrial production in both Europe and the United States, but has not yet fully recovered to the peak levels of 2007-2008. • Generally more robust market conditions prevailed from 2010 to early 2011, with higher consumption and prices for most pulp, paper and paperboard commodities. • Prices reached a plateau by late 2010 and may have peaked in a cycle that began with rebound from the global financial crisis of 2008-2009; but prices still remained high in early 2011. • The Russian Federation is seeing an almost complete recovery of pulp and paper output to the levels that preceded the global financial crisis of 2008-2009. • European pulp, paper and paperboard output rebounded in 2010 after declining in 2008-2009, but the production levels before the crisis have not yet been reached. • Similarly, US production of pulp, paper and paperboard all rebounded from the sharp declines of 2008-2009, but production levels in 2010-2011 remained below previous cyclical peak levels. • A major project to expand use of larch was initiated in the Russian Federation, while wood pellet output and wood energy use also expanded in the Russian pulp and paper industry. • The market rebound coincides with expanding industry interest in the contributions of paper and paperboard products to green and sustainable development. • Green and sustainable product features such as use of renewable resources and product recyclability help support sustainability initiatives and an evolving symbiotic relationship between pulp and paper market development and the green economy. -
Effects of Fiber Weight Ratio, Structure and Fiber Modification Onto Flexural Properties of Luffa-Polyester Composites

A unsaturated polyester matrix reinforced with a mat of Luffa external wall fibers (ComLEMat), a short Luffa external wall fibers (ComLEBC) and a short Luffa core fi- bers (ComLCBC) was fabricated under various conditions of fibers treatments (combined process, acetylat- ing and cyanoethylating) and fiber weight ratio. It resorts that acetylating and cyanoethylating enhance the flexural strength and the flexural modulus. The fiber weight ratio influenced the flexural properties of com- posites. Indeed, a maximum value of strength and strain is observed over a 10% fiber weight ratio. The uses of various reinforcement structures were investigated. The enhancement of elongation at break and the strain values of the composite reinforced by natural mat was proved. Keywords: Luffa Fibers, Composite, Flexural Properties, Fiber Weight Ratio 1.

Holmen Paper Magazine Study
THE FUTURE OF MAGAZINES MARKET STUDY BY HOLMEN PAPER With the past decades’ rapid digital evolution, print media in almost all forms has taken a step back. As a company selling printing paper, Holmen Paper has observed and experienced this decline first hand. Newspapers was the first segment that suffered a rapid decrease in readers and is, as a result, no longer the largest end-use segment for graphical paper. Instead magazines now hold that position. Hence the future of the magazine market is crucial to the future of graphical paper. This is why we decided to conduct this study, where we look at how publishers meet the new challenges, how pricing is affected and how the readers demands are changing. TABLE OF CONTENTS MARKET SELLING PRICE 3 OVERVIEW 13 VS ADVERTISING How is the magazine market developing? What sets the price of a magazine? SHIFT IN MILLENNIALS’ BUSINESS READING 7 MODELS 16 HABITS Are the publishers’ changes radical enough? What does this group want in a printed magazine? Understanding where the magazine market is heading, helps you to gain insights and make sound future business decisions. This study therefore starts by looking at the current state of the magazine market, including historic developments as well as forecasted development. It then proceeds to look at the market from a publisher’s perspective, based on qualitative interviews with European publishers. The outcome is an extensive summary of the challenges that many publishers are experiencing, but also how they adapt their business models to to overcome them. The study also includes a thorough analysis of a large number of consumer magazines, where attributes such as price versus advertising density are investigated. -
