    Molnbaserade affärssystem: Viktiga aspekter vid övergång till molnet2013Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Det saknades teori kring vilka aspekter som var viktiga för potentiella kunder att väga in i ett beslut om övergång till molnbaserade affärssystem. I undersökningen har vi samlat tidigare forskning kring molntjänster generellt och sedan jämfört den med empiri från respondenter med erfarenhet av molnbaserade affärssystem. På så sätt har vi försökt koppla tidigare forskning och undersökt huruvida den är applicerbar på vår studie. Vi kom fram till att det framförallt är aspekter rörande säkerhet, ekonomi och affärsstrategi som kunder bör vara medvetna om när de planerar en övergång till molnbaserade affärssystem. Rörande säkerhet fann vi att det är viktigt att tänka på hur den fysiska lagringen sker och säkerhetsrutiner kring vem som handhar data och hur den säkerhetskopieras samt vem som äger datan. Ekonomiskt kan beslutet om en övergång påverkas av molntjänsters olika prismodeller, hur kostnader skiljer sig mot lokalt installerade system samt potentiellt dolda kostnader. Slutligen kan det affärsstrategiskt finnas avgörande aspekter i hur system interagerar med varandra, hur anpassad en tjänst är till mobila enheter samt att molntjänster enkelt kan skalas upp i storlek vid behov.

    Architecture and Gene Repertoire of the Flexible Genome of the Extreme Acidophile Acidithiobacillus caldus2013Inngår i: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 8, nr 11, artikkel-id e78237Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Acidithiobacillus caldus is a sulfur oxidizing extreme acidophile and the only known mesothermophile within the Acidithiobacillales. As such, it is one of the preferred microbes for mineral bioprocessing at moderately high temperatures. In this study, we explore the genomic diversity of A. caldus strains using a combination of bioinformatic and experimental techniques, thus contributing first insights into the elucidation of the species pangenome. Principal Findings: Comparative sequence analysis of A. caldus ATCC 51756 and SM-1 indicate that, despite sharing a conserved and highly syntenic genomic core, both strains have unique gene complements encompassing nearly 20% of their respective genomes. The differential gene complement of each strain is distributed between the chromosomal compartment, one megaplasmid and a variable number of smaller plasmids, and is directly associated to a diverse pool of mobile genetic elements (MGE). These include integrative conjugative and mobilizable elements, genomic islands and insertion sequences. Some of the accessory functions associated to these MGEs have been linked previously to the flexible gene pool in microorganisms inhabiting completely different econiches. Yet, others had not been unambiguously mapped to the flexible gene pool prior to this report and clearly reflect strain-specific adaption to local environmental conditions. Significance: For many years, and because of DNA instability at low pH and recurrent failure to genetically transform acidophilic bacteria, gene transfer in acidic environments was considered negligible. Findings presented herein imply that a more or less conserved pool of actively excising MGEs occurs in the A. caldus population and point to a greater frequency of gene exchange in this econiche than previously recognized. Also, the data suggest that these elements endow the species with capacities to withstand the diverse abiotic and biotic stresses of natural environments, in particular those associated with its extreme econiche.

    Högstadiets fysiklektioner och ”en dator per elev”: Vilken potential ser lärare och hur upplever de den?2019Independent thesis Basic level (professional degree), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Svenska grundskolan närmar sig en tid när alla elever har egna datorer. Vissa lärare har arbetat med detta i många år och andra bara några. Frågan som undersöks i denna uppsats är vilken potential fysiklärare ser i denna utveckling och hur de upplever potentialen. Sju naturvetenskapslärare från Sydsverige intervjuades på ett semistrukturerat sätt och data analyserades med en fenomenografisk ansats. Resultatet visar att den potential som lärare beskriver kan kategoriseras som skapande, innehåll och interaktion men att det finns störningar som påverkar alla kategorier. Analys av hur lärare upplever potentialen belyses med följande kategorier; noggrannhet, effektivitet, flexibilitet och illustrativ. Uppsatsen försöker att undersöka både de negativa och positiva aspekterna inom dessa kategorier. Vidare forskning som undersöker hur elever upplever dessa kategorier av potential skulle kunna bidra till en bättre helhetsbild.

    Market Entry Strategy for InternationalFirms in South East Asia: A Case Study of Vietnam2013Independent thesis Advanced level (degree of Master (One Year)), 20 poäng / 30 hpOppgave
    Abstract [en]

    With projected economy growth rates of 5.5 percent over 2013 to 2017 (OECD, 2013),countries in South East Asia (SEA) are predicted a robust and resilient economicperspective. Consequently, this is accompanied by increased interest from internationalfirms of all size aiming at market shares. However, market entry appears to be prone todifficulties as high failure and withdrawing rates of foreign companies demonstrate. Thisstudy, therefore, contributes to the understanding of how emerging country markets canbe entered strategically, by evaluating how internal and external conditions can affectmarket entry strategy and how previous internationalization theory can be applied.Vietnam, as an example for a SEA country, comes with high economic growth rates,which have created vast business and growth opportunities for companies of all size andindustries. The case is examined based on a medium sized subsidiary of a Germancompany group, located in neighboring China, currently aiming at market entry inVietnam. As academic literature determines markets as business networks and entryprocess consequently as establishing an adept position built on relationships, it isassumed that entry strategy into Vietnam first of all depends on detecting the expedientanchor points within the complex environment of Vietnam. As, from a resource basedperspective scholars, furthermore, assume competitive advantage to rest in a firm´sparticular set of resources and capabilities, a successful market entry is considered todepend on establishing relationships into this network based on the firms inherentresources. The research was conducted by investigating the company’s resources,capabilities and its entry motives for Vietnam, the impact of the external environment inVietnam as well as appropriate strategies for gaining legitimacy from it. Empirically,findings are based on a qualitative single case study of the case company supported byinterviews with key company personnel and various Vietnam experts. Thorough analysisshowed that the case company’s market entry strategy is heavily impacted by weaknessesin brand management, which appeared to be necessity on customer side for the sale ofhigh involvement products in Vietnam, as well weaknesses in its sales managementconcerning the non-transferability of its current sales staff. External influences, such ashigh impact of the government, complicated retaining of labor; As a result forweaknesses on side of the company and difficulties in the market, a direct entry modewas recommended to the case company.

    Abstract

    Today Sweden has 341 ice hockey arenas, around 140 outdoor ice hockey rinks, 60 ice fields for bandy and about 35 curling arenas. In addition, the numbers of indoor bandy arenas are increasing. The cooling systems installed today should be able to lower its energy consumption with 10-30%.In this thesis, Ronneby ice-arena has been researched. This artificial cooling facility was inaugurated 2011 and is one of the newest in Sweden. This is an outdoor ice field for bandy and therefor has no roof or walls to cover the field. Ronneby ice-arena has problems with uneven cooling distribution of the ice field. This results in cracks and uneven ice quality. These problems also result in higher energy consumption than necessary.To find a solution for the uneven cooling of the ice field flow measurements were carried out in the brine circuit. To get a better understanding of the cooling distribution, temperature measurements were carried out on the brine feeding lines. A calculation has been performed on what energy savings a speed control of the brine circulation pumps depending on the outdoor temperature could generate. Another calculation was made to see the possible savings with a windshield around the field. In this thesis the benefits of a heat recovery system on the cooling compressors refrigerant has been investigated. The heat recovery system could heat the locker rooms, the clubhouse, the showers and the hot water for the Zambonis.In order to perform the necessary calculation for this thesis, Fredriksbergs BK and Ronneby municipality provided operating data.The actions proposed to Ronneby ice-arena to solve the uneven cooling of the ice field is to change the location of the brine feeding line connection point. At the same time this work is carried out it’s suggested that the brine feed and return lines get insulated. When the uneven cooling problems have been solved, a speed control system should be installed to control the brine circulation pumps, in order to lower the electricity consumption. Ronneby ice-arena has the possibility to install a heat recovery system. Therefore it is suggested to install a heat exchanger on each cooling compressor refrigerant. This installation is to be used to heat the clubhouse, the showers and the hot water for the Zambonis. The system to cool the condensers with seawater and currently the heat pump are not optimal designed. The installed heat pump does not work when the seawater temperature is below 5°C, therefore the system should be redesigned.

    Abstract [en]

    Environmental – economic pressure and associated regulations have led to a significant increase of recycled paper as the main fibrous component of corrugated board the last years. Corrugating packaging industry is facing the challenge to enhance products derived from recycled pulp and to ensure a satisfactory strength of packages. Advanced techniques are highly needed for the evaluation of packaging fiber supply sources as well as for the utilization of the available resources in an optimal manner. As industrial packaging is based on the characteristics of its constituent fibers, information on the fiber composition of the recycled raw materials is of primary importance for a continual control of fiber sources. This paper reports on the usefulness of fiber analysis techniques as diagnostic methods for assessing the potential quality distribution of fibers for sustainable packaging manufacturing.

    Abstract [en]

    Values of pure moduli of elasticity (PMOE), experimental modulus of elasticity (MOE) in static bending and moduli of rigidity (GLR, GLT) were calculated in juvenile and mature black locust defect-free small wood specimens after loading in static bending alternately on true radial and tangential surfaces. For both juvenile and mature specimens, no significant differences (t-test, 95% probability level) were found between the radial and tangential moduli of elasticity and rigidity. Values of PMOE were found to be 27–32% higher than the corresponding values of MOE at the 15:1 span-to-depth ratio.

    Identification of Fibre Components in Packaging Grade Papers2006Inngår i: IAWA Journal, ISSN 0928-1541, Vol. 27, nr 2, s. 153-172Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Environmental and economic issues have led to a significant increase of recycled paper as the main fibrous component of corrugated board the last years. Qualitative data on the different fibre types are needed for the evaluation of packaging fibre supply sources, which are becoming numerous and heterogeneous. Fifteen different packaging grade papers (7 linerboards and 8 corrugating medium) were selected to represent all the variety of papers available on the Spanish market. The origin of virgin and recycled fibres was identified by their morphological characteristics employing light microscopy and standard fibre analysis techniques. The waste-based papers (Waste based-liners and Fluting), Kraft-liners and Test-liner were highly variable containing 9–18 different wood and nonwood components. Semi-chemical, with 5–13 components, was the less variable grade. Hardwoods were identified as the most important fibre component from a quantitative standpoint. All papers contained in their hardwood mix Betula, Eucalyptus and Populus in significant amounts. Fagus sylvatica and Tilia were also frequently observed and in some papers were amongst major hardwood components. Prominent softwood components were found to be Pinus sylvestris, P. pinaster, P. radiata, Picea, Larix and in some papers Pinus nigra. The lower presence of a variety of softwood, hardwood and nonwood (mainly grasses) species and genera was due to the paper recycling process.

    Influence of hot-water extractives on radial and tangential shrinkage of black locust wood (Robinia pseudoacacia L.)2002Inngår i: European Journal of Wood and Wood Products, ISSN 0018-3768, E-ISSN 1436-736X, Vol. 60, nr 5, s. 377-378Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    IntroductionRemoval of extractives increases the shrinkage and swelling of wood (Nearn 1955, Salamon and Kozak 1968, Cooper 1974, Taylor 1974). The effect of progressive extraction on the above properties has not been investigated much. In oak (Quercus conferta L.), a forest species rich in extractives, the shrinkage progressively increased with progressive extraction (Voulgaridis et al. 1980). In black locust (Robinia pseudoacacia L.), much of the main-stem volume is comprised of heartwood, characterized by the presence of dark yellow-brown extractives. While the extractives of black locust give the heartwood its distinctive color and decay resistance, they comprise only 6.2 to 8.3% of the dry weight of the main stem (Stringer 1992). Hot-water extractives range from 5.2 to 8.6% (Hart 1968, So et al. 1980). The present study was primarily undertaken to determine whether the progressive removal of hot-water extractives affects the radial and tangential shrinkage of black locust heartwood.

    Abstract [en]

    This study determined percentages by weight of the fiber components in 15 papers commonly used to produce corrugating packaging in Spain. The papers are manufactured mainly from recycled raw materials. The percentages were determined by means of standard quantitative fiber analysis techniques and use of appropriate weight factors. Hardwoods were the major fiber component in all papers, except kraft liners, varying from 51% to 92% per weight. Kraft liners had greater softwood content (49%-69%)than hardwood, and the most plentiful softwood classes were pines. Douglas-fir was a contaminating fiber component (weight percentage less than 2%) in almost in every paper. Nonwood fibers, entering the papers through the recycling process, were a significant fiber component (2%-9%) in most of the papers, especially the waste-based papers (liners and flutings). Quantitative fiber composition reflects the differences in quality between the papers. Its usefulness could be further explored in the quality control of paper manufacturing for packaging.

    Application: Packaging grade papers incorporate a variety of wood and nonwood fiber types. Manufacturing of papers of consistent and acceptable quality requires knowledge concerning the quantity of each fiber used.

    Abstract [en]

    Promoting sustainable raw material management and increasing the recycling of waste wood and waste rubber are two strategic thrusts that open large domains for new technologies and innovations.

    This project, in line with objectives of LIFE+ Environment Policy & Governance aims to increase resource efficiency through the utilization of these wood and rubber wastes through the manufacturing of new products based on innovative mixed composites (wood/rubber). This new products will constitute an alternative for the utilization of other traditional and less eco-efficient products in the residential and civil construction sector.

    Moreover, the project will provide a novel end of life route for wood waste managers and rubber waste managersʼ products and entities a new environmental friendly product to public and private construction sector.The use of these products will increase the carbon storage in buildings and replace other building materials which are less environmentally friendly towards carbon storage and emission, both in production processes and raw material use.

    The recovered wood category to be utilised will be waste wood from households (furniture, doors, windows, floors, etc.). This material is chemically contaminated by glues, lacquers, paints and coatings but not by preservatives. After collection, the waste wood material will be chipped and processed in the form of chips without any prior biological, thermal or chemical treatment. This is an innovative approach since the removal of all these chemicals is difficult and time/ cost consuming.

    Recovered rubber form tyres in the form of particles, free from other materials as wires, ropes, synthetic fibres, etc., will be utilised with recovered wood chips or sawn timber for the production of innovative composite products by thermal processes.

    This project is in line with latest research in wood – rubber applications (Yang et al. 2004, Zhao et al. 2008).

    Acoustic properties of acetylated wood under different humid conditions and its relevance for musical instruments2018Inngår i: Proceedings of the 9th European Conference on Wood Modification 2018, Arnhem, The Netherlands / [ed] Jos Creemers, Thomas Houben, Bôke Tjeerdsma, Holger Militz and Brigitte Junge, The Netherlands: Practicum , 2018, s. 236-243Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In musical instrument making, less expensive wood species and materials with good characteristics and acoustical properties can provide potentials to find alternatives to the traditional exotic wood species used today. Modified wood could be such a choice if shows similar sound characteristics to wood coming from endangered and expensive tropical species with problematic commercial availability. In musical instruments, the overall functionality depends on the contribution of wood to different material performance indexes like sound radiation coefficient (R), characteristic impedance (z) and acoustic conversion efficiency (ACE). In this study, the performance indexes were measured for acetylated beech, maple and radiata pine and compared with these obtained for the reference wood materials maple, mahogany, alder and ash. A non-destructive free-free flexural vibration test method was used at constant temperature (20oC) but in different humid conditions- dry (35% RH), standard (65% RH) and wet (85% RH). Dimensional changes in the different humid conditions were also taken in account. Acetylated wood showed lower EMC with higher dimensional stability at each humidity level as compared with the reference wood materials. These properties are considered important factors for making quality musical instruments. Based on the acoustical properties, acetylated wood materials, especially radiata pine, showed good potential for use for musical instruments where specific characteristics of sound are required. However, the other types of acetylated wood can also be used for specific musical instruments.

    Adhesive bonding of beech wood modified with a phenol formaldehyde compound2012Inngår i: European Journal of Wood and Wood Products, ISSN 0018-3768, E-ISSN 1436-736X, Vol. 70, nr 6, s. 897-901Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Untreated (controls) and phenol–formaldehyde (PF)-modified beech wood (10 and 25 % solid content) were glued with phenol resorcinol formaldehyde (PRF) and polyvinyl acetate (PVAc). Shear strength of PRF-bonded specimens was higher than that of PVAc-bonded ones under dry and wet conditions irrespective of the pre-treatment. Under dry conditions, only PVAc-bonded specimens exhibited reduction in shear strength due to PF-modification with 25 % PF concentration as compared to the controls. PF treated wood provided inferior bonding under wet conditions with the exception of 25 % PF concentration specimens glued with PRF adhesive. Modification with PF resulted in a decrease of adhesive penetration into the porous network of interconnected cells, especially at 25 % PF concentration.

    Use and properties of recovered paper raw materials for the production of corrugated board2015Inngår i: Proceedings of the 14th International Conference on Environmental Science and Technology Rhodes, Greece, 3-5 September 2015, Global NEST , 2015Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The difficulty of predicting the properties of paper products produced from heterogeneous sources puts several limitations, which therefore lead to severe economic losses and only a comprehensive characterization will enable their better utilization. The project “RF-CORRUG –Quality control of raw materials from recovered fibres for the production of corrugated board”under the NationalStrategic Reference Framework 2007–2013 ARCHIMEDES IIIdeals with this common technical problem of the corrugated board industry. Specifically, the mainobjective of the project is to supportthe competitiveness of the corrugated board companies (mainly SMEs)by creatinga software tool based on practical models that can predict packaging grade paper properties from fibre data (qualitative, quantitative, morphological) used in their production. This paper presents information on the physical and mechanical properties of recovered packaging papers used in corrugated packaging. A number of different category papers (liners, flutings) used for corrugated board production in Greece were examined. The required paper properties included grammage, porosity, bursting strength, SCT, tensile strength and tearing resistance, and were measured by internationally recognized testersand standards. The data will be used to develop predictive models based on advanced statistical methods for the properties and performance of packagingaccording to information of their recovered raw paper materials.

    Disregarding shear effects is a principal defect in predicting the bending strengths of small clear specimens of timber according to standards. The present study proposes a method to determine spans of 2 x 2 cm wood specimens of black locust and chestnut for shear free deformations in static bending. It was found that for both ring-porous species, spans of at least 40 cm in a bending test would ensure a negligible influence of shear on modulus of elasticity.

    Effect of cambium age and ring width on density and fibre length of black locust and chestnut wood2010Inngår i: Wood research, ISSN 1336-4561, Vol. 55, nr 3, s. 25-36Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The relationship between wood density (WD) and fibre length (FL) with cambium age (CA) and ring width (RW) was studied in two ring-porous species, black locust and coppice-grown chestnut, collected in the Sithonia Peninsula, Chalkidiki, Greece. Using regression analysis methods, models of WD and FL in relation to CA and RW were obtained. It was found that the effect of CA and RW on WD and FL was similar for both species examined. WD of black locust and chestnut was predicted better through a model using CA and RW. A model for FL variations was also obtained with CA and RW and was more accurate than the simple models based on the two factors, CA and RW, separately. The multiple regression models suggested that the use of cambial age of growth rings together with their width might explain better their effects on WD and FL of black locust and chestnut.

    Manufacturing and properties of gypsum-based products with recovered wood and rubber materials2015Inngår i: BioResources, ISSN 1930-2126, E-ISSN 1930-2126, Vol. 10, nr 3, s. 5573-5585Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The experimental production of gypsum-based products (cylindrical samples, solid bricks) using different fractions of wood chips and rubber particles was studied. Recovered rubber and wood materials were mixed with gypsum and water in various proportions to fabricate gypsum-wood and gypsum-rubber cylindrical samples and standard solid bricks with six holes using appropriate molds. It was shown that to manufacture gypsum-wood and gypsum-rubber products with good mechanical strength, coarse fractions of wood and rubber should be used, but the proportion of wood or rubber should not exceed 25%. No thermal conductivity differences were found between the wood-and rubber-type of gypsum products, and particle size and material proportion had no effect. Samples with fine wood and rubber particles present at a lower proportion (25%) exhibited similar sound absorption behavior. The solid bricks had slightly higher strength when loaded at the large surface of their lateral upper side than when loaded at the small surface. The bricks provided better thermal insulation than both the extruded and pressed house bricks but lower than that of insulating bricks. The emission of volatile organic compounds out of the bricks was at an acceptable level according to regulations for construction products.

    Resistance of Pinus leucodermis heartwood and sapwood against the brown-rot fungus Coniophora puteana2012Inngår i: Wood Material Science & Engineering, ISSN 1748-0272, E-ISSN 1748-0280, Vol. 7, nr 4, s. 242-244Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This study assessed the decay resistance of Pinus leucodermis wood to the brown-rot fungus Coniophora puteana. Based upon the median weight losses of 30.65% for heartwood and of 34.68% for sapwood obtained in the biological tests, both the heartwood and sapwood material examined was classified as not durable (durability class 5) according to the CEN/TS 15083-1 classification. Total extractives were low, 3.93% in heartwood and 1.00% in sapwood, while lignin content was 22.60% and 25.41% in heartwoodand sapwood, respectively. It is highly recommended to use protective treatments before using P.leucodermis wood in outdoor conditions.

    Tensile strength of handsheets prepared with macerated fibres from solid wood modified with cross-linking agents2015Inngår i: Holzforschung, ISSN 0018-3830, E-ISSN 1437-434X, Vol. 69, nr 8, s. 959-966Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This study was conducted to explain the tensile strength loss of wood due to the modification with 1,3-dimethylol-4,5-dihydroxyethyleneurea (DMDHEU) and glutaraldehyde (GA). Modified and control wood blocks were macerated to deliberate fibres, and handsheets were produced thereof. The nitrogen content of the fibres indicated that maceration removed the major proportions of DMDHEU. The stability of GA in wood during maceration was not assessed. Tensile strength determined at zero span (z-strength) and finite span (f-strength) was equal for the handsheets from DMDHEU-modified fibres and the control handsheets. The microscopic appearance of the tested finite-span paper strips from DMDHEU-modified fibres mainly indicated interfibre failure and did not differ from the fibre fracture mode of the control handsheets. In contrast, the z-strength of the handsheets from GA-modified fibres was lower than that of controls and decreased with increasing content of GA in the initial modified wood. The f-strength behaviour of the handsheets from GA-modified fibres was the opposite: it was higher than that of controls and increased with increasing GA content. The microscopic appearance of the rapture zones of the finite-span testing mainly indicated intrafibre failure for the GA-modified fibres. It was concluded that cross-linking is likely to be the major reason for tensile strength loss of GA- and DMDHEU-modified wood. In terms of DMDHEU-modified wood, the incrustation of the cell wall by the resin and the reduction in pliability could play an additional role.

    Mathematical approach for defining juvenile-mature wood transition zone in black locust and chestnut2011Inngår i: Wood and Fiber Science, ISSN 0735-6161, nr 3, s. 336-342Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This article defines age of transition from juvenile to mature wood in two ring-porous species, black locust (Robinia pseudoacacia L.) and chestnut (Castanea sativa Mill.). A logistic function was proposed using fiber length and ring width data of three black locust trees, aged 35-37 yr, and five chestnut coppice trees, aged 25-27 yr, from Sithonia Peninsula, Chalkidiki, Greece. The approach proved to be practical and objective in delineating maturity zones, and it was based on rate of change of yearly fiber length. The juvenile wood zone spread to the sixth growth ring from the pith in both species, whereas the demarcation of juvenile and mature wood was at age 12 and 14 yr in chestnut and black locust, respectively. Transition zone width comprised rings 7-12 in chestnut and rings 7-14 in black locust.

    Predicting the Properties of Corrugated Base Papers Using Multiple Linear Regression and  Artificial Neural Networks2016Inngår i: Drewno, ISSN 1644-3985, Vol. 59, nr 198, s. 61-72Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The difficulty in predicting the properties and behaviour of paper products produced using heterogeneous raw materials with high percentages of recovered fibres poses restrictions on their efficient and effective use as corrugated packaging materials. This work presents predictive models for the mechanical properties of corrugated base papers (liner and fluting-medium) from fibre and physical property data using multiple linear regression and artificial neural networks. The most significant results were obtained for the prediction of the tensile strength of liners in the cross direction from the origin (wood type, pulp method) of the fibres using linear regression, and the prediction of the compressive strength of fluting-medium in the longitudinal (machine) direction, according to the short-span test, using a neural network with one hidden layer with 6 neurons, with coefficients of determination at 95.14% and 99.28%, respectively

    Abstract [en]

    It was studied the recovery of wood chips from waste particleboards by immersion in water at ambient temperature and by mechanical treatment (agitation and impact, waterblasting). Four different categories of waste particleboards were used, with and without coating, after their reduction in smaller pieces with dimensions of about 7 × 8 cm.  The investigated methods were: (I) immersion for 3 days-impregnation with vacuum and pressure-agitation and impact (II) immersion for 7 days-drying-rewetting for 12 hours-agitation and impact (III) immersion for 3 days-waterblasting. The maximum thickness swelling (about 90%) was achieved by immersing the particleboards in the water for 3 days, and therefore the vacuum and pressure impregnation step can be omitted in practice. Recovery of wood chips was significantly higher (51.54%) in the case of successive wetting and drying cycles compared to simple immersion in water (17.32%). Both these methods I and II, involving agitation and impact for recovering wood chips from waste particleboards, are easily applicable at the industry. Method III with waterblasting resulted in complete recovery of wood chips within a very short time, but its application requires more research

    Wood structure and topochemistry of Juniperus excelsa2011Inngår i: IAWA Journal, ISSN 0928-1541, Vol. 32, nr 1, s. 67-76Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Wood structure and topochemical distribution of lignin and phenolic extractives in Juniperus excelsa Bieb. were investigated using a mature specimen, aproximately 80 years of age, from the Rhodope mountains, Greece. The wood of J. excelsa was found to possess the same qualitative anatomical features as those reported for other Juniperus species of the Western Hemisphere. Quantitative anatomical characteristics recorded for mature wood (heartwood and sapwood) included earlywood and latewood tracheid length, double wall thickness of earlywood and latewood tracheids, lumen diameter of earlywood tracheids and ray height. Scanning UV microspectrophotometry revealed a pronounced lignification of J. excelsa tracheids with detected absorbance values of the secondary cell wall layers being much higher in comparison to all other softwoods studied using this technique. The cell corners and compound middle lamellae were characterised by relative high UV absorbance values as compared to the S2 layers. The phenolic compounds deposited in the axial and ray parenchyma cells possessed higher absorbance values than cell wall associated lignins and had a different spectral behaviour due to the presence of chromophoric groups. According to the obtained UV absorbance spectra, more condensed phenolic compounds were deposited in the heartwood than in the sapwood.

    Characterization of packaging grade papers from recycled raw materials through the study of fibre morphology and composition2007Inngår i: Global NEST. International Journal, ISSN 1108-4006, Vol. 9, nr 1, s. 20-28Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The restrictions in availability of forest-based raw materials along with favourable environmental policies towards alternative sources of raw materials have forced corrugated packaging industry to shift towards recycled paper and other fibre sources such as non-wood and agro-residues. The variability in raw pulp materials with increasing percentages of recycled fibres is a very common technical problem for the corrugated packaging industry worldwide. Corrugating packaging production is facing the challenge to ensure a satisfactory strength of packages despite the increase of recycled paper as the main fibrous component. Sustainable manufacturing of papers of consistent and acceptable quality requests comprehensive characterization of the fibrous components, which are becoming more heterogeneous. Understanding the influence that heterogeneous recycled raw materials have on packaging grade paper properties offers great potential value to the corrugated board and packaging industry.

    57 linerboards and corrugating medium were selected to represent all the variety of paper grades available on the market at the moment for the production of corrugated board in Spain. The papers were analyzed for their fibre morphology (fibre length, fibre width, lumen diameter, cell wall width and flexibility) and fibre composition (softwood to hardwood and nonwood fibre count and weight) and their strength (compression, bursting and crushing resistance) was evaluated. All the determinations were in accordance with the relevant TAPPI Test Methods. The significant differences found in most of the anatomical characteristics, fibre composition and strength properties among the paper grades reflected the diverse raw materials used for their production as well as their qualitative differences. By means of simple correlation the influence of fibre characteristics and composition on the strength of the papers was determined under two different conditions, at 23 o C and 50% RH and at 20 o C and 90% RH.

    The results demonstrate that besides the physical-mechanical characterization of packaging grade papers, fibre anatomy and composition can be used successfully as a complementary practical test to predict the performance of papers. The application of the predicting correlations is proposed for the evaluation of the fibre supplies for the packaging industry. An enormous potential for cost reduction can be created by the selection of the most appropriate and inexpensive combination of grade papers for a specific packaging use

    Ring width, latewood proportion and dry density in stems of Pinus brutia Ten2009Inngår i: European Journal of Wood and Wood Products, ISSN 0018-3768, E-ISSN 1436-736X, Vol. 67, nr 4, s. 471-477Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This study examined basic characteristics of stem wood produced in Pinus brutia Ten. reforestations in Northeastern Greece. Sixteen dominant trees growing at good and medium site qualities were felled at 14–22 years. Site quality classification was based on site quality surrogates and confirmed by using site index curves that were created for a neighbouring area. Discs were taken at three stem positions (base, middle, top) to study variations in ring width, latewood proportion and dry density. Generally, at both good and medium sites, ring width was found to increase towards the top of the stems while latewood proportion and dry density showed a negative relationship with stem height. Radial variability trends were similar at all heights, and at both sites, revealing a rapid increase for ring width in the first 3–6 annual rings followed by a decrease towards the bark, a gradual increase for latewood proportion and no specific change for dry density. Comparisons between wood material produced during the same growth period (2005–2001) showed statistically significant differences among sampling heights in all cases except for dry density in medium sites. At the base of the stems, mean ring width and dry density were significantly (P ≤0.05) higher at good sites (3.6 mm and 0.53 g/cm3) than at medium sites (3.0 mm and 0.50 g/cm3). However, the differences between the sites are of small magnitude and therefore have limited practical impact on wood processing. The availability of such data is useful in utilising small-dimension timber of brutia pine.

    Fiber composition of packaging grade papers as determined by the Graff “C” staining test2006Inngår i: Wood and Fiber Science, ISSN 0735-6161, Vol. 38, nr 4, s. 567-575Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    A qualitative and quantitative analysis of the fiber components of 15 representative papers that are used for the production of corrugated board was carried out by the Graff "C" staining test. The method of processing of softwood, hardwood, and nonwood fibers was determined under a light microscope by their color reactions with the stain. All papers, due to the use of recycled pulp raw materials in their manufacturing, were found to incorporate in their furnish fibers that had been produced with a variety of pulping processes: chemical, mechanical, and semi-mechanical. The recycled-based papers (recycled-liner and recycled-medium) were proved to be the most variable comprising 12-15 different fiber components, while in some of the semi-chemicals only up to 7 components were identified. The weight percentages of the fiber components calculated by the application of weight factors showed that in almost all papers the most important fiber component from a quantitative standpoint was hardwood unbleached kraft followed by softwood unbleached kraft. Besides hardwood unbleached semi-chemical pulp and mechanical softwood pulp that were also plentiful in the papers, there was a smaller number of other components which sum, however, accounted for a significant fraction in the total furnish weight. The results taken on the total softwood, hardwood, and nonwood fibers content of the papers demonstrate that Graff "C" staining test is adequate to analyze both the structure and quality of packaging grade papers in practical industrial testing.

    Corrugated packaging production is currently facing the challenge to ensure a satisfactory strength of packaging despite the continuous increase in recycled paper as the main fibrous component. This research addresses a very common technical problem for the corrugated board industry – the difficulty of predicting the properties of paper products produced from heterogeneous sources. Grammage and structural density, being easily available data, were examined as quality parameters of the most common categories of packaging paper in Europe. Grammage, ranging from 100 to 225 g/m2, has been found to be a dominant parameter for estimating the strength properties of paper.

    Ring width, latewood proportion and density relationships in black locust wood of different origins and clones2010Inngår i: IAWA Journal, ISSN 0928-1541, Vol. 31, nr 2, s. 169-178Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Cross-sectional discs were cut at breast height from 19 black locust trees aged 18–39 years of different clones and origin (Greece, Bulgaria and Hungarian clones J, U and NY). Ring width, latewood proportion and dry density were measured according to standard laboratory techniques in order to examine their relationships. Latewood proportion was found to increase (except for one tree from Bulgaria) with increasing ring width and logarithmic equations were calculated with relatively high correlation coefficients. A positive relation between dry density and latewood proportion was found in black locust of Bulgarian origin and in the Hungarian clone NY while in all other cases no meaningful relationship was observed. In mature wood, improved positive linear correlations were observed between dry density and latewood proportion with the exception of the Hungarian clone U. Regression analysis revealed low correlations between dry density and ring width and only black locust from Bulgaria had a high positive correlation. The positive correlations between dry density and ring width were slightly improved in mature wood with the exception of clone J from Hungary.

    Strength properties of juvenile and mature wood in black locust (Robinia pseudoacacia L.)2007Inngår i: Wood and Fiber Science, ISSN 0735-6161, Vol. 39, nr 2, s. 241-249Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This study was undertaken to investigate the strength properties of juvenile and mature wood in black locust (Robinia pseudoacacia L.). Wood specimens were prepared from various stem heights, up to 9 m, of five naturally-grown black locust trees, 21-37 years old. Mechanical properties tested included moduli of rupture (MOR) and elasticity (MOE), and pure modulus of elasticity (PMOE) in static bending, stress wave modulus of elasticity (SWMOE) in dynamic strength, axial compression, and toughness. Comparisons between juvenile and mature wood specimens of similar densities (0.667-0.894 g/cm3 and 0.682-0.892 g/cm3, respectively) showed that juvenile wood had a statistically significant lower mean MOR (138.78 N/mm2), MOE (13,936 N/mm2), PMOE (18,125 N/mm2), SWMOE (16,813 N/mm2) and toughness strength (155.25 KJ/m2) than the mature wood (148.29 N/mm2, 14,747 N/mm2, 19,498 N/mm2, 17,635 N/mm2 and 181.27 KJ/m2, respectively). On the contrary, no statistically significant differences were found for the mean strength in axial compression among juvenile (63.75 N/mm2) and mature wood (66.65 N/mm2). Fractured surfaces of juvenile and mature wood specimens in static bending and toughness were classified into the "splintering tension" type of failure, while compression failures were of the "shearing type" according to ASTM D 143-83 standards. Lower strength of juvenile wood in most of the properties examined may be attributed to anatomical and chemical properties rather than density of wood specimens. The adverse influence of juvenile wood on strength properties should be considered for effective management (e.g. longer rotation age and other genetic and forest or plantation management measures that reduce juvenile wood content) and utilization of the species.
