Seed biometric parameters in oil palm accessions from a Brazilian germplasm bank

The objective of this work was to evaluate the morphological diversity of oil palm seeds and to cluster the accessions according to their morphological characteristics. Forty-one accessions from the oil palm germplasm bank of Embrapa Amazônia Ocidental were evaluated - 18 of Elaeis oleifera and 23 of E. guineensis. The groups were formed based on morphological characteristics, by principal component analysis. In E. oleifera, four groups were formed, tied to their region of origin, but with significant morphological differences between accessions from the same population. For tenera-type E. guineensis seeds, three widely divergent groups were formed, especially as to external parameters, which differentiated them from the other ones. The parameter endocarp thickness stood out in intra- and inter-population differentiation. For dura-type E. guineensis, three groups were formed, with larger seeds and thicker endocarps, which differed from all the other ones. The variability observed for seed characteristics in the analyzed accessions allows the establishment of different groups, to define strategies for genetic improvement.

Fish oil replacement by soybean oil in the diet of fat snook juveniles

The objective of this work was to evaluate fish oil replacement by soybean oil in diets, as for the effects on the performance and body composition of juveniles of fat snook (Centropomus parallelus). The experiment was carried out in a randomized block design, with three treatments (lipid sources) and six replicates, in a 60-day period. Fat snook juveniles (24.17±0.28g) were distributed in 18 experimental tanks of 200 L each, equipped with aeration and heating systems, under continuous water renovation (800% per day). Three isoproteic (44% CP) and isoenergetic (4,635 kcal CE kg-1) diets were formulated to comprise three replacement rates (0, 50, and 100%) of fish oil by soybean oil. Biometric analyses were done to evaluate fish performance, and two entire specimens from each replicate were used for body composition analyses. The zootechnical indices of weight gain (38.68±5.41 g), feed conversion (1.38±0.10), and specific growth at 1.70±0.18% weight gain per day were considered satisfactory. Lipid source substitution does not affect the performance and body composition of fat snook juveniles, which suggests that soybean oil can replace fish oil in diet formulation.

In vitro maintenance, under slow-growth conditions, of oil palm germplasm obtained by embryo rescue

The objective of this work was to evaluate the in vitro maintenance of oil palm (Elaeis guineensis and E. oleifera) accessions under slow-growth conditions. Plants produced by embryo rescue were subject to 1/2MS culture medium supplemented with the carbohydrates sucrose, mannitol, and sorbitol at 1, 2, and 3% under 20 and 25±2ºC. After 12 months, the temperature of 20°C reduced plant growth. Sucrose is the most appropriate carbohydrate for maintaining the quality of the plants, whereas mannitol and sorbitol result in a reduced plant survival.

Scenarios for electricity power sector development in the North-West of Russia

Focus of this thesisis made on development of electricity sector of Russian North-West. The objective was to determine the most likely scenarios for development of the most critical (western) part of Interregional Power System of North-West, from where the most part of Russian electricity exports to the countries of European Union take place. For this purpose all the involved sides were analyzed: generation, transmission system and electricity consumption in different regions of Russian North-West. The analysis was performed through investigation of existing generation andtransmission capacities and plans for their development to be performed by the generation and transmission companies operating in the region. Principles of Russian electricity sector restructuring and electricity market design are also discussed as well as factors that may influence on future electricity price in the region.

Gender and Security Sector Reform: Gendering Differently?

Recent efforts to implement gender mainstreaming in the field of security sector reform have resulted in an international policy discourse on gender and security sector reform (GSSR). Critics have challenged GSSR for its focus on 'adding women' and its failure to be transformative. This article contests this assessment, demonstrating that GSSR is not only about 'adding women', but also, importantly, about 'gendering men differently' and has important albeit problematic transformative implications. Drawing on poststructuralist and postcolonial feminist theory, I propose a critical reading of GSSR policy discourse in order to analyse its built-in logics, tensions and implications. I argue that this discourse establishes a powerful 'grid of intelligibility' that draws on gendered and racialized dualisms to normalize certain forms of subjectivity while rendering invisible and marginalizing others, and contributing to reproduce certain forms of normativity and hierarchy. Revealing such processes of discursive in/exclusion and marginalized subjectivities can serve as a starting point to challenge and transform GSSR practice and identify sites of contestation.

Scandinavian companies of banking, retailing and hotel sectors investing into the Baltic States-developing service sector

Diplomityö tehtiin Lappeenrannan yliopistossa päätavoitteenaan selvittää tärkeimmät motiivit, jotka ovat saaneet pohjoismaiset palvelualan yrityksetinvestoimaan Baltian maiden kehittyvillä markkinoilla. Pohjoismaiset yritykset ovat olleet aiemmin aktiivisia hyödyntämään Baltian maiden työvoimaa tuotantosektorilla. Suomalaiset yritykset ovat investoineet aiemmin telekommunikaatio- sekävaatetussektoreihin, mutta nykyisin investointien pääpaino on siirtynyt palvelualalle. Pankkisektori on erittäin kehittynyt pohjoismaissa ja ruotsalaiset yritykset ovat onnistuneet myös Baltiassa siirtyen markkinoille yksityistämisen tuomien mahdollisuuksien avulla. Nykyisin näillä yrityksillä on vahva jalansija Virossa sekä ovat etabloituneet myös Latviaan ja Liettuaan. Suomalaiset pankkialan yritykset ovat olleet vaatimattomampia tällä sektorilla. Vähittäiskauppiaat ovat vasta kansainvälistymisprosessinsa alkutaipaleella. Suomalaiset yritykset ovat laajentuneet Viroon ja tehneet yhteistyötä ruotsalaisten yritysten kanssa. Hotellisektorilla suomalaiset ja ruotsalaiset ovat edenneet rauhallisesti, mutta norjalainen ketju, Reval Hotel, on laajentunut kaikkiin Baltian maihin. Hotellisektorilla on luvassa kasvua lähivuosina. Kilpailutilanne on kiristynyt kaikilla palvelualan sektoreilla sekä paikallisten yritysten kasvun että ulkomaisten investoijien myötä. Elinolojen paraneminen vaikuttaa myös kilpailutilanteeseen kiristävästi, sillä se luo mahdollisuuksia yrityksille laajentua. Tämä diplomityö selvittäätilannetta valittujen yritysten kannalta niiden kansainvälistymisen alkutaipaleella.

La responsabilidad social corporativa en el sector de la moda en España: el caso Inditex

El segle XXI ha estat l’escenari de grans transformacions. Entre d’altres, el de l’empresa socialment responsable. Ens trobem en un nou context en el qual s’entén que les empreses, i especialment les grans empreses transnacionals, no busquen només maximitzar els seus beneficis a qualsevol preu. Per contra, el que ens trobem és un nou paradigma sobre el compromís de l’empresa amb els drets humans i el medi ambient, el que ha vingut a anomenar-se el comportament socialment responsable de l’empresa o, de forma més planera, la Responsabilitat Social Corporativa (RSC). Tot i això, segueixen essent molt els mitjans que, cada cop amb més freqüència, donen a conèixer nous escàndols protagonitzats per aquestes grans empreses: treballadors explotats, drets laborals violats, ecosistemes destruïts, etc. D’això hom entén que el debat al voltant del paper de les grans empreses encara no s’ha conclòs. Aquest treball pretén trobar noves evidències sobre la pràctica de la RSC. Amb aquest propòsit s’ha decidit realitzar un estudi en detall del Grupo Inditex, una de les empreses de referència a l’Estat espanyol, líder nacional i internacional del sector de la moda. Pensant en aquest objectiu, el treball comença analitzant les aproximacions teòriques a la RSC: com la podem entendre, quin paper juga en l’empresa i quines són les raons de la seva implementació. El segon capítol estudia així mateix els orígens d’aquesta pràctica i n’analitza les problemàtiques principals, a saber: els mètodes de valoració, els mecanismes de regulació i les eines de gestió. Com a pas previ a l’anàlisis del cas pràctic, el tercer capítol estudia dos grans marcs d’anàlisis: el del sector de la moda a Espanya i la trajectòria del Grupo Inditex, empresa líder del tèxtil. Un cop acabat aquest exercici, el quart capítol estudia en detall la RSC del Grupo d’acord amb dues fonts principals: els Informes de RSC que el Grupo elabora anualment, d’una banda, i els estudis de grups independents, en especial els de l’Observatori de la RSC i els que es realitzen en el marc de la Campaña Ropa Límpia, de l’altre.

Effectiveness of antioxidants in preventing oxidation of palm oil enriched with heme iron: A model for iron fortification in baked products

Bakery products such as biscuits, cookies, and pastries represent a good medium for iron fortification in food products, since they are consumed by a large proportion of the population at risk of developing iron deficiency anemia, mainly children. The drawback, however, is that iron fortification can promote oxidation. To assess the extent of this, palm oil added with heme iron and different antioxidants was used as a model for evaluating the oxidative stability of some bakery products, such as baked goods containing chocolate. The palm oil samples were heated at 220°C for 10 min to mimic the conditions found during a typical baking processing. The selected antioxidants were a free radical scavenger (tocopherol extract (TE), 0 and 500 mg/kg), an oxygen scavenger (ascorbyl palmitate (AP), 0 and 500 mg/kg), and a chelating agent (citric acid (CA), 0 and 300 mg/kg). These antioxidants were combined using a factorial design and were compared to a control sample, which was not supplemented with antioxidants. Primary (peroxide value and lipid hydroperoxide content) and secondary oxidation parameters (p-anisidine value, p-AnV) were monitored over a period of 200 days in storage at room temperature. The combination of AP and CA was the most effective treatment in delaying the onset of oxidation. TE was not effective in preventing oxidation. The p-AnV did not increase during the storage period, indicating that this oxidation marker was not suitable for monitoring oxidation in this model.

Análisis de la Garantía de Origen como mecanismo de cambio hacia un sector eléctrico más sostenible

La Garantía de Origen, como sistema de certificación de electricidad en función de su origen, fue introducida en España en 2007 y abrió la posibilidad de comercializar y consumir electricidad procedente únicamente de fuentes renovables. Resulta interesante abordar la evolución y el estado actual de este instrumento desde distintas aproximaciones para entender que potencial tiene para provocar cambios en los mecanismos de producción, comercialización y consumo de la electricidad encaminados a hacer el sector más sostenible. Este proyecto muestra como la Garantía incide sobre los patrones de la comercialización y el consumo de la electricidad y, a partir de ahí, es capaz de inducir cambios importantes en la estructura del sector eléctrico haciendo depender más de las fuentes renovables y menos de los combustibles fósiles.

Distribution systems of the food sector in Russia: the perspective of Finnish food industry

Finnish food producers' trade with Russia has experienced profound changes since the collapse of the Soviet Union. Simultaneously, the distribution systems of foodstuffs have changed remarkably. This study sheds some light into these changes and analyses the current situation in distribution systems of foodstuffs in Russia. In addition, the study discusses the possibilities of Finnish food producers to get more of their products to the shelves of Russian food retail stores. Before the 1998 financial crisis, the import of foreign foodstuffs was booming in Russia due to the overvalued rouble. As a result of the financial crisis, food import collapsed. The export of Finnish foodstuffs to Russia has been slowly recovering during the past few years, but in the most important product categories the pre-crisis levels have so far not been reached and maybe will not be reached. In certain product categories the growth has been only marginal. It seems that starting localproduction will become increasingly important in the future. This is further encouraged by the fact that Russian consumers favour domestic food products. Russian consumers are very price conscious and demand quality in food products. The perceived price-quality ratio is an important criterion in the purchase decision.The majority of foodstuff retail is still conducted via unorganised forms of trade (e.g. kiosks and marketplaces) but modern retail chains are developing at a fast pace in Russia. They are also expected to dominate the retail trade in foodstuffs over the unorganised forms of trade in the future. This will change the distribution systems as well. The retail chains are trying to shorten the distribution chain, similarly to what has been seen in the Western countries. This together with the strengthening of retail chains is likely to shrink the role of wholesalers, as the chains increasingly want to work directly with the producers. Many large retail chains are acquiring or have already acquired a distribution centre or centres in order to boost efficiency and control the flow of products. The strengthening of the retail chains also gives them power in negotiations, which the producers and distributors have to adjust to. For example store entry fees and retail chains' own private label products pose challenges to the food producers. In the food production sector the competition is fierce, as large Russianand foreign producers want to ensure their piece of the market. The largest producers utilise their size: they invest in big marketing campaigns and are willing to pay high entry fees to retail chains in order to secure a place on the store shelves and to build a strong brand in Russia. This complicates the situation from the viewpoint of small producers. Currently, the most popular type of distribution system among the interviewed Finnish food producers is based on a network of local distributors. There is, however, a strong consensus on the importanceof starting local production in order to be a serious actor in Russia in the future. Factors that hinder the starting of local production include the lack of local infrastructure and qualified staff, and the low risk tolerance of Finnish firms. Major barriers for entry in Russia are the actions of authorities, fierce competition, fragmented market and Finnish producers' heavy production costs. The suggested strategies for increasing the market share include focusing geographically or segment-wise, introducing new products, starting local production, andcooperation between Finnish producers. Smallness was one reason why Finnish producers had to cut down their operations in Russia due to the 1998 crisis. Smaller producers had fewer resources to tolerate losses during the period of crisis. Smallness is reflected also on trade negotiations with retail chains and distributors. It makes it harder to cope with the store entry fees and to differentiatefrom the mass of products propped up by expensive advertising. Finally, it makes it harder for Finnish producers to start or expand local production, as it is more difficult for a small producer to get financing and to tolerate the increased risks. Compensating for the smallness might become the crucial factor determining the future success of Finnish food producers in the Russian market.

Solid and liquid biofuels markets in Finland - a study on international biofuels trade

This study considered the current situation of solid and liquid biofuels markets and international biofuels trade in Finland and identified the challenges ofthe emerging international biofuels markets for Finland. The fact that industryconsumes more than half of the total primary energy, widely applied combined heat and power production (CHP) and a high share of biofuels in the total energy consumption are specific to the Finnish energy system. One third of the electricity is generated in CHP plants. As much as 27% of the total energy consumption ismet by using wood and peat, which makes Finland the leading country in the use of biofuels. Finland has made a commitment to maintain greenhouse gas emissions at the 1990 level at the highest during the period 2008-2012. The Finnish energypolicy aims to achieve the target, and a variety of measures are taken to promote the use of renewable energy sources and especially wood fuels. In this study, the wooden raw material streams of the forest industry were included the international biofuels trade in addition to biomass streams that are traded for energy production. In 2004, as much as 45% of the raw wood importedinto Finland ended up in energy production. The total international trading of biofuels was evaluated at 72 PJ, of which the majority, 58 PJ, was raw wood. About 22% of wood based energy in Finland originated from imported raw wood. Tall oil and wood pellets composed the largest export streams of biofuels. The annual turnover of international biofuels trade was estimated at about ¤ 90 million fordirect trade and at about ¤ 190 million for indirect trade. The forest industryas the biggest user of wood, and the producer and user of wood fuels has a central position in biomass and biofuels markets in Finland. Lately, the international aspects of Finnish biofuels markets have been emphasised as the import of rawwood and the export of wood pellets have increased. Expanding the use of biofuels in the road transportation sector would increase the international streams ofbiofuels in Finland. In coming years, the international trading of biomass for energy purposes can be expected to continue growing.
