Succeeding in price and quality competition is not possible on a domestic basis alone. Adjusting to globalization is vital for the Finnish pulp and paper industry. Expanding production to other continents is indispensable so that the future competitiveness of domestic production can also be ensured. Finnish industry cannot respond to the needs of customers around the world on a domestic basis alone.. Succeeding in global competition is just as indispensable for the Finnish forest industries now as internationalization and the resulting consolidation and strong growth were a few decades ago. If bold steps had not been taken then, in all probability the Finnish forest industries would today consist of subsidiary mills directed from head offices abroad, more likely to shrink than to grow.. The operating model for the global paper industry in the coming years is quite clear. Pulp mills will be built in South America and Russia. Paper and board machines will be located in Asia, especially China. In ...

A simple filter paper method was developed for, the transport and storage of monoclonal antibodies (Mabs) at room temperature or -20°C after spotting on filter paper, for subsequent serotyping of outer membrane antigens of N.meningitidis by dot-blot ELISA. Monoclonal antibodies (Mabs) were spotted within a 0.5-1 cm diameter area of Whatman grade 903 paper, which were stored individually at room temperature or at -20°C. These MAbs were stored and analyzed after periods of one week, 4 weeks, 12 months, or 13 years in the case of frozen Mab aliquots, or after 4 weeks at -20°C or at room temperature (RT) in the case of Mabs dried on filter paper strips. Assays were performed in parallel using dot-blot ELISA. In addition to the MAbs specific for serotyping class 1, 2 or 3, we used a larger number of Mabs for polysaccharides, lipooligosaccharides (LOS), class 5 and cross-reactive antigens for native outer membrane of N.meningitidis. The Mabs dried on filter paper were eluted with phosphate-buffered saline
A superabsorbent polymer having improved absorption under pressure and fast absorption rate is obtained by first providing a solution containing carboxylic acid monomers or water soluble salts thereof, and a crosslinking agent. A carbonate blowing agent and a polymerization initiator are added, individually or in combination, to the solution to form a carbonated monomer solution. A polymerization initiator is then added to the carbonated monomer solution which is then polymerized at temperatures ranging from about 0 C. to about 130 C., forming a microcellular hydrogel. The microcellular hydrogel is chopped or ground into gel pieces having a particle diameter ranging from about 0.1 mm to about 5.0 cm. The gel pieces are dried at temperatures ranging from about 85 C. to about 210 C., and are then ground to form a polymer having a particle size of from about 0.05 mm to about 5.0 mm. A mixture is formed from 100 parts by weight of the polymer and about 0.001 to about 30 parts by weight of a surface

A method and device for detecting analytes in a test sample. Embodiments include methods for quantitatively detecting analytes within a range of concentrations. In an embodiment the method includes a lateral flow test strip with multiple test areas for capturing a labeled receptor to provide a detectable signal.
Lateral flow test devices. These are test kits designed to be used to test a sample for the presence of a specific chemical or substance. Examples of such tests include pregnancy tests, though many other tests using the same technique are also available. The underlying principle is an immunoassay analysis, where the sample moves along the test substrate by capillary action. When the sample reaches points on the substrate impregnated with antibodies or antigens, coloured lines are formed indicating a positive or negative result. Sample windows are round; result line windows (T, test; C, control) are rectangular. - Stock Image C011/4248

The experiences of past efforts of industrial pollution control while maintaining competitiveness should be of great value to research and policy practice addressing sustainability issues today. In this article, we analyze the environmental adaptation of the Swedish pulp industry during the period 1970-1990 as illustrated by the sulfite pulp producer Domsjö mill. We investigate how this company managed to adapt to heavy transformation pressure from increasing international competition in combination with strict national environmental regulations during the 1960s to the early 1990s. In line with the so-called Porter hypothesis, the company was able to coordinate the problems that were environmental in nature with activities aiming at production efficiency goals and the development of new products. Swedish environmental agencies and legislation facilitated this
In this study, we have confirmed the validity of the filter paper method for studying release of IL-1β into rectal mucosal fluid and have extended its application to the measurement of TNF-α and the eicosanoids TXB2 and PGE2.. The results of the in vitro recovery experiments indicated that the use of the filter paper technique in vivo was feasible for IL-1β, TNF-α, TXB2, and PGE2. However, recovery of IFN-γ from the filter paper in vitro, regardless of its incubation time, was very low. The inability to elute this cytokine from the filter paper satisfactorily precluded reliable evaluation of rectal mucosal release in vivo using the filter paper method.. The paired in vivo validation experiments showed that there was considerable intraindividual variation for the filter paper method, particularly for those patients with active UC and the control group. The coefficient of variation (CV) of paired filter papers from the same individuals (intraindividual variation) was higher than the reported ...
As the evidence of the toxic effects of bisphenol A (BPA) grows, its application in commercial products is gradually being replaced with other related compounds, such as bisphenol S (BPS). Nevertheless, very little is known about the occurrence of BPS in the environment. In this study, BPS was analyzed in 16 types of paper and paper products (n = 268), including thermal receipts, paper currencies, flyers, magazines, newspapers, food contact papers, airplane luggage tags, printing paper, kitchen rolls (i.e., paper towels), and toilet paper. All thermal receipt paper samples (n = 111) contained BPS at concentrations ranging from 0.0000138 to 22.0 mg/g (geometric mean: 0.181 mg/g). The overall mean concentrations of BPS in thermal receipt papers were similar to the concentrations reported earlier for BPA in the same set of samples. A significant negative correlation existed between BPS and BPA concentrations in thermal receipt paper samples (r = −0.55, p < 0.0001). BPS was detected in 87% of ...
Filter paper is a semi-permeable paper barrier placed perpendicular to a liquid or air flow. It is used to separate fine substances from liquids or air. Filter paper has various properties. The important parameters are wet strength, porosity, particle retention, volumetric flow rate, compatibility, efficiency and capacity. There are two mechanisms of filtration with paper; volume and surface. By volume filtration the particles are caught in the bulk of the filter paper. By surface filtration the particles are caught on the paper surface. Filter paper is mostly used because even a small piece of filter paper will absorb a significant volume of liquid The raw materials are different paper pulps. The pulp may be from softwood, hardwood, fiber crops, mineral fibers. For high quality filters, dissolving pulp and mercerised pulp are used. Most filter papers are made on small paper machines. For laboratory filters the machines may be as small as 50 cm width. The paper is often crêped to improve ...
