Abstract Flavors represent a small but significant segment of food industry. Sensory characteristics play an important role in the process of consumer acceptance and preference. Indocalamus leaf takes on a pleasant odor and indocalamus leaf flavor can be used in many products. However, indocalamus leaf flavor formula has not been reported. Therefore, developing an indocalamus leaf flavor is of significant interests. Note is a distinct flavor or odor characteristic. This paper concentrates on preparation and creation of indocalamus leaf flavor according to the notes of indocalamus leaf. The notes were obtained by smelling indocalamus leaf, and the results showed that the notes of indocalamus leaf flavor can be classified as: green-leafy note, sweet note, beany note, aldehydic note, waxy note, woody note, roast note, creamy note, and nutty note. According to the notes of indocalamus leaf odor, a typical indocalamus leaf flavor formula was obtained. The indocalamus leaf flavor blended is pleasant, harmonious, and has characteristics of indocalamus leaf odor.

INTRODUÇÃO: A desnutrição é uma complicação frequente nos pacientes em hemodiálise, sendo o diagnóstico precoce importante para reduzir as taxas de morbidade e mortalidade do tratamento. OBJETIVO: Investigar a utilidade dos exames bioquímicos mensais realizados na hemodiálise para triagem de pacientes com desnutrição. MÉTODOS: O diagnóstico nutricional de 252 pacientes foi feito através da avaliação objetiva e subjetiva global, classificando-os em desnutridos e não desnutridos. Paralelamente, durante 4 meses consecutivos, as concentrates de creatinina, fósforo, ureia pré-e pósdiálise e o Kt/V foram registradas para cálculo das médias. Após análise dessas variáveis através da curva ROC, calculouse a sensibilidade e a especificidade na identificação dos pacientes com desnutrição. RESULTADOS: Na curva ROC, a área sob a curva para a ureia foi de 0,683, para o fósforo 0,71, para o Kt/V 0,724 e para a creatinina 0,765. Para valores de ureia < 90 mg/dL; fósforo < 4,2 mg/dL; Kt/V > 1,6 e creatinina < 6,5 mg/dL, a especificidade variou entre 80% e 88% e a sensibilidade entre 26 % e 51% . O valor preditivo negativo variou entre 90% e 92% e o valor preditivo positivo entre 23% e 32%. A associação de dois ou mais desses índices não modificou de forma significante esses valores. CONCLUSÕES: Nossos resultados sugerem que valores de ureia < 90 mg/dL, creatinina < 6,5 mg/dL, fósforo < 4,2 mg/dL e Kt/V > 1,6 podem ser utilizados para triagem de pacientes com desnutrição.

This study concentrates on developing a suitable business model for Finnish biobanks, with particular emphasis on value creation to stakeholders. The sub-objective of this thesis are to map the commercial possibilities of biobanks and potential barriers for business development. The study approaches the subject from the biobanks’ as well as the stakeholders’ point of view, integrating their hopes and needs considering current and future co-operation into the findings. In 2013 the Biobank Act came into effect, after which six biobanks have been established and several other pending biobank projects are in process. There is relatively little research in regard to the commercial opportunities of this newcomer of the biomedical industry, and particularly in the Finnish markets. Therefore, the aim of this study is to partially fill the research gap of the commercial potential of biobanks and particularly outline the problematic elements in developing business. The theoretical framework consists of a few select theories, which depict business modeling and value creation of organizations. The theories are combined to form a synthesis, which best adapts to biobanks, and acts as a backbone for interviews. The empirical part of the study was conducted mainly by seven face-to-face interviews, and complemented by two phone interviews and an e-mail questionnaire with four responses. The findings consist mainly of the participants’ reflections on the potential products and services enabled by consumer genomics, as well as perceptions on different obstacles for biobanks’ business development. The nature of the study is tentative, as biobanks are relatively new organizations in Finland, and their operation models and activities are still molding. The aim is to bring to surface the hopes and concerns of biobanks’ representatives, as well as the representatives of stakeholders, in order to transparently discuss the current situation and suggestions for further development. The study concludes that in principle, the interviewees’ agree on the need for development in order not to waste the potential of biobanks; regardless, the participants emphasize different aspects and subsequently lean on differing methods.

The electricity distribution sector will face significant changes in the future. Increasing reliability demands will call for major network investments. At the same time, electricity end-use is undergoing profound changes. The changes include future energy technologies and other advances in the field. New technologies such as microgeneration and electric vehicles will have different kinds of impacts on electricity distribution network loads. In addition, smart metering provides more accurate electricity consumption data and opportunities to develop sophisticated load modelling and forecasting approaches. Thus, there are both demands and opportunities to develop a new type of long-term forecasting methodology for electricity distribution. The work concentrates on the technical and economic perspectives of electricity distribution. The doctoral dissertation proposes a methodology to forecast electricity consumption in the distribution networks. The forecasting process consists of a spatial analysis, clustering, end-use modelling, scenarios and simulation methods, and the load forecasts are based on the application of automatic meter reading (AMR) data. The developed long-term forecasting process produces power-based load forecasts. By applying these results, it is possible to forecast the impacts of changes on electrical energy in the network, and further, on the distribution system operator’s revenue. These results are applicable to distribution network and business planning. This doctoral dissertation includes a case study, which tests the forecasting process in practice. For the case study, the most prominent future energy technologies are chosen, and their impacts on the electrical energy and power on the network are analysed. The most relevant topics related to changes in the operating environment, namely energy efficiency, microgeneration, electric vehicles, energy storages and demand response, are discussed in more detail. The study shows that changes in electricity end-use may have radical impacts both on electrical energy and power in the distribution networks and on the distribution revenue. These changes will probably pose challenges for distribution system operators. The study suggests solutions for the distribution system operators on how they can prepare for the changing conditions. It is concluded that a new type of load forecasting methodology is needed, because the previous methods are no longer able to produce adequate forecasts.

This thesis develops a method for identifying students struggling in their mathematical studies at an early stage. It helps in directing support to students needing and benefiting from it the most. Thus, frustration felt by weaker students may decrease and therefore, hopefully, also drop outs of potential engineering students. The research concentrates on a combination of personality and intelligence aspects. Personality aspects gave information on conation and motivation for learning. This part was studied from the perspective of motivation and self-regulation. Intelligence aspects gave information on declarative and procedural knowledge: what had been taught and what was actually mastered. Students answered surveys on motivation and self-regulation in 2010 and 2011. Based on their answers, background information, results in the proficiency test, and grades in the first mathematics course, profiles describing the students were formed. In the following years, the profiles were updated with new information obtained each year. The profiles used to identify struggling students combine personality (motivation, selfregulation, and self-efficacy) and intelligence (declarative and procedural knowledge) aspects at the beginning of their studies. Identifying students in need of extra support is a good start, but methods for providing support must be found. This thesis also studies how this support could be taken into account in course arrangements. The methods used include, for example, languaging and scaffolding, and continuous feedback. The analysis revealed that allocating resources based on the predicted progress does not increase costs or lower the results of better students. Instead, it will help weaker students obtain passing grades.

The purpose of this paper is to discuss the main characteristics of new Lula's government support. The paper's hypothesis concentrates in the idea of starting a different political approach, "a new populism". The paper argues that Lula's government to keep in power, beyond of going on with the neoliberal project - unfinished in the last years of FHC government -, needs to build up a solid and trustful political support, which is being done by implementing income transfer programs directed to poor people and the ones with less organization experience. This paper also calls the attention to Lula's government nature, in order to clarify the difficulties which should be dealt and the tasks to be developed in building up a political party that defends workers emancipation and Brazilians exploited.

Viimeaikaisen talouden yleisen heikon tilanteen johdosta päättäjät ympäri Eurooppaa ovat kääntyneet pienten ja keskisuurten yritysten (pk-yritys) puoleen työllisyyden parantamiseksi. Pk-yritysten edustaessa yli 99% Suomen yrityskannasta, ovat ne erittäin tärkeässä asemassa työllisyystilanteen lisäksi myös maamme talouden kannalta, ja pk-yrityksille onkin asetettu kasvupaineita viimeaikaisten kasvuyritysten menestystarinoiden innoittamana. Tässä tutkimuksessa pääasiallisena tavoitteena on tutkia pk-yritysten kasvuun liittyviä tekijöitä kasvun mahdollistavien sekä kasvua rajoittavien tekijöiden kannalta. Pääasiallisen tavoitteen ohella on tutkittu myös pk-yritysten tekemiä konkreettisia toimia kasvua mahdollistavien tekijöiden vahvistamiseksi, sekä kasvua rajoittavien tekijöiden murtamiseksi. Tutkimus etenee siten, että ensin käydään läpi pk-yritysten kasvuun liittyviä yleisiä asioita, jonka jälkeen siirrytään kasvun mahdollistaviin ja sitä rajoittaviin tekijöihin. Tutkimus on toteutettu laadullisena tutkimuksena eli se on kvalitatiivinen tutkimus. Tutkimuksen empiirinen aineisto koostuu neljän pk-yrityksen teemahaastatteluista, sekä kyselylomakkeesta, joissa kartoitettiin pk-yritysten omistaja-johtajien mielipiteitä yritysten kasvun mahdollistavista ja sitä rajoittavista tekijöistä. Teemahaastattelujen haastattelurunko on rakennettu pk-yritysten kasvua käsittelevien artikkelien ja niissä ilmenneiden kasvuun liittyvien havaintojen pohjalta. Tutkimuksen perusteella pk-yritysten omistaja-johtajat ovat sitä mieltä, että Suomen veropoliittiset, sekä työlainsäädännölliset ratkaisut rajoittavat yritysten kasvua, eivätkä kannusta yrittäjyyteen. Tämän lisäksi kasvua rajoittavat omistaja-johtajien tavoitteet yritystoimintaan liittyen, sekä pätevän työvoiman rekrytointiin liittyvät ongelmat. Kasvun mahdollistavien tekijöiden osalta omistaja-johtajat pitivät tärkeinä yritystoimintaa tukevien järjestelmien merkitystä, yrityksen tunnetuksi tekemistä, yrityksen ja sen sidosryhmien välisten suhteiden kehittämistä ja yhteistyötä sekä yritystoiminnan laadun kehittämistä ja valvontaa. Tutkimuksessa ilmeni myös pk-yritysten pystyvän murtamaan aikaisemmissa tutkimuksissa ilmenneitä kasvua rajoittavia tekijöitä tehokkaasti, saavan aikaan kasvua niiden olemassaolosta huolimatta.

This thesis researches the current state of small teleoperated devices, the need for them and developing one. Small teleoperated devices give the possibility to perform tasks that are impossible or dangerous for humans. This work concentrates on small devices and cheap components and discloses one way of developing a teleoperated vehicle, but not necessarily the optimal way. Development and the current state of teleoperation were studied by a literature review, in which the data was searched from literature as well as from the Internet. The need for teleoperated devices was mapped through a survey, where 11 professionals from variating fields were interviewed how they could utilize a teleoperated devices and with what kind of features. Also, a prototype was built as a proof of concept of small teleoperated devices. The prototype is controlled by a single-board microcomputer that also streams video to the controlling device. The video can be viewed on a display or with a head mounted display.

On March 15 2012, we lost Professor Alice Amsden, a great intellectual power in development economics. Her work was systematically marked by creativity, originality, relevance and her fearless commitment to always speak truth to power both in academic as well as in policy-making arenas. This In Memoriam concentrates on just one part of her great intellectual legacy: her impact to better understanding Latin America's development challenges, obstacles and policy options. Our paper focuses on three broad areas of her main influence in the region: the role of transnational corporations, the importance of manufactured exports for development, and industrial policy. As we here argue, in all of them, her work is and continues to be a substantial contribution to knowledge that policy makers will be well advised to take into account if the region is to finally enter a path of structural transformation and sustained economic and social development.

The purpose of this study is to investigate the challenges of the adaptation process of education export. The research is conducted as a single case study that concentrates on three education export projects. The case company in the research is Team Academy. The study goes through the different forms of education export, the adaptation of education export and the challenges of the education export –process by means of theory and empirical data. The research is carried out as a qualitative research and the method used is a qualitative content analysis. More specifically the research is an abductive content analysis. The research data is collected in four in-depth interviews from Team academy representatives who have been strongly involved in certain education export –project of Team Academy. The research confirms the theory in the challenge of hierarchy, funding and registration issues, and refutes it in the challenge of competition, legislation, different governmental attitudes and knowledge in productization. The main challenges of the adaptation process are related to funding, differences in values, sudden changes, the complex nature of the learning model, concept of time, teamwork as method and accreditation. It is highlighted that in the future operations, anticipating problems that arise from for example cultural differences and differences in values, communication, managing the money flows and the company form is recommended. Future research could continue with investigating the suitable company form for education exports of this kind, and how to stand out and communicate when operating under another institution. It is considered a potential risk that a brand encloses the brand that operates under it.

The increasing performance of computers has made it possible to solve algorithmically problems for which manual and possibly inaccurate methods have been previously used. Nevertheless, one must still pay attention to the performance of an algorithm if huge datasets are used or if the problem iscomputationally difficult. Two geographic problems are studied in the articles included in this thesis. In the first problem the goal is to determine distances from points, called study points, to shorelines in predefined directions. Together with other in-formation, mainly related to wind, these distances can be used to estimate wave exposure at different areas. In the second problem the input consists of a set of sites where water quality observations have been made and of the results of the measurements at the different sites. The goal is to select a subset of the observational sites in such a manner that water quality is still measured in a sufficient accuracy when monitoring at the other sites is stopped to reduce economic cost. Most of the thesis concentrates on the first problem, known as the fetch length problem. The main challenge is that the two-dimensional map is represented as a set of polygons with millions of vertices in total and the distances may also be computed for millions of study points in several directions. Efficient algorithms are developed for the problem, one of them approximate and the others exact except for rounding errors. The solutions also differ in that three of them are targeted for serial operation or for a small number of CPU cores whereas one, together with its further developments, is suitable also for parallel machines such as GPUs.
