Energia, meio ambiente e economia: o Brasil no contexto mundial

The cycle of fossil fuels as an energy source for mankind is approaching its end. Finite resources, coupled with greenhouse gas, have led to an increased effort in the search for alternative renewable energy sources. Brazil has a leading position, due to a 46% participation of renewable sources in its primary energy supply, compared to the global average of 12%. The expansion of the renewable sources in Brazil depends on medium and long term planning, and a large volume of investments. The present financial crisis will have major effects in the energy market. Despite a negative initial impact, it is expected that the rearrangement of the financial system will ultimately lead to an expansion in the use of renewable energy sources. Brazil is a tropical country, with the largest biodiversity in our planet and excellent conditions to expand the use of all forms of renewable sources.

Produção científica e formação de recursos humanos na área de bioquímica em instituições federais do Rio Grande do Sul: fomento estadual

Brazilian scientific production in Biochemistry is growing impressively fast, and Rio Grande do Sul is outstanding in that context. This study aims to outline the state's scientific research profile, given its prominent position in the national scenario. Hence, researchers, laboratories, development of human resources and investments by Foundation for the Support to Research in the State of Rio Grande do Sul (FAPERGS) were identified and mapped. We observed that amount of financial support by FAPERGS decreases in last years. Therefore, there is the necessity to reestablish some of FAPERGS's programs, as well as to increase financial support to Biochemistry departments.

Development of Russian Ports in The Gulf of Finland

Russia has been one of the fastest developing economic areas in the world. Based on the GDP, the Russian economy grew evenly since the crisis in 1998 up till 2008. The growth in the gross domestic product has annually been some 5–10%. In 2007, the growth reached 8.1%, which is the highest figure after the 10% growth in 2000. Due to the growth of the economy and wage levels, purchasing power and consumption have been strongly increasing. The growing consumption has especially increased the imports of durables, such as passenger cars, domestic appliances and electronics. The Russian ports and infrastructure have not been able to satisfy the growing needs of exports and imports, which is why quite a large share of Russian foreign trade is going through third countries as transit transports. Finnish ports play a major role in transit transports to and from Russia. About 15% of the total value of Russian imports was transported through Finland in 2008. The economic recession that started in autumn 2008 and continues to date has had an impact on the economic development of Russia. The export income has decreased, mainly due to the reduced world market prices of energy products (oil and gas) and raw minerals. Investments have been postponed, getting credit is more difficult than before, and the ruble has weakened in relation to the euro and the dollar. The imports are decreasing remarkably, and are not forecast to reach the 2008 volumes even in 2012. The economic crisis is reflected in Finland's transit traffic. The volume of goods transported through Finland to and from Russia has decreased almost in the same proportion as the imports of goods to Russia. The biggest risk threatening the development of the Russian economy over long term is its dependence on export income from oil, gas, metals, minerals and forest products, as well as the trends of the world market prices of these products. Nevertheless, it is expected that the GDP of Russia will start to grow again in the forthcoming years due to the increased demand for energy products and raw minerals in the world. At the same time, it is obvious that the world market prices of these products will go up with the increasing demand. The increased income from exports will lead to a growth of imports, especially those of consumer goods, as the living standard of Russian citizens rises. The forecasts produced by the Russian Government concerning the economic development of Russia up till 2030 also indicate a shift in exported goods from raw materials to processed products, which together with energy products will become the main export goods of Russia. As a consequence, Russia may need export routes through third countries, which can be seen as an opportunity for increased transit transports through the ports of Finland. The ports competing with the ports of Finland for Russian foreign trade traffic are the Russian Baltic Sea ports and the ports of the Baltic countries. The strongest competitors are the Baltic Sea ports handling containers. On the Russian Baltic Sea, these ports include Saint Petersburg, Kaliningrad and, in the near future, the ports of Ust-Luga and possibly Vyborg. There are plans to develop Ust-Luga and Vyborg as modern container ports, which would become serious competitors to the Finnish ports. Russia is aiming to redirect as large a share as possible of foreign trade traffic to its own ports. The ports of Russia and the infrastructure associated with them are under constant development. On the other hand, the logistic capacity of Russia is not able to satisfy the continually growing needs of the Russian foreign trade. The capacity problem is emphasized by a structural incompatibility between the exports and imports in the Russian foreign trade. Russian exports can only use a small part of the containers brought in with imports. Problems are also caused by the difficult ice conditions and narrow waterways leading to the ports. It is predicted that Finland will maintain its position as a transit route for the Russian foreign trade, at least in the near future. The Russian foreign trade is increasing, and Russia will not be able to develop its ports in proportion with the increasing foreign trade. With the development of port capacity, cargo flows through the ports of Russia will grow. Structural changes in transit traffic are already visible. Firms are more and more relocating their production to Russia, for example as regards the assembly of cars and warehousing services. Simultaneously, an increasing part of transit cargoes are sent directly to Russia without unloading and reloading in Finland. New product groups have nevertheless been transported through Finland (textile products and tools), replacing the lost cargos. The global recession that started in autumn 2008 has influenced the volume of Russian imports and, consequently, the transit volumes of Finland, but the recession is not expected to be of long duration, and will thus only have a short-term impact on transit volumes. The Finnish infrastructure and services offered by the logistic chain should also be ready to react to the changes in imported product groups as well as to the change in Russian export products in the future. If the development plans of the Russian economy are realized, export products will be more refined, and the share of energy and raw material products will decrease. The other notable factor to be taken into consideration is the extremely fast-changing business environment in Russia. Operators in the logistic chain should be flexible enough to adapt to all kinds of changes to capitalise on business opportunities offered by the Russian foreign trade for the companies and for the transit volumes of Finnish ports, also in the future.

Impactos da nanotecnologia na saúde: produção de medicamentos

Several studies have described the benefits of nanoscience and nanotechnology (N&N) in different sectors such as agriculture, energy, environmental preservation, and public health. The rapid evolution of N&N can be shown through a panoramic analysis of scientific papers and patents. In the area of public health, it is estimated that the global market for nanotechnology products will expand to 160 billion U.S. dollars in 2015. The Brazilian government has also strengthened its innovative potential in N&N through economic subsidies, as observed for other countries. This review is focused on the current landscape of N&N in a therapeutic context, highlighting the development of nanotech-products produced with biocompatible and biodegradable materials that are already commercially available or under investigation. Most studies under investigation are focused on the development of nanotechnology-based formulations intended for treatment of cancer, inflammatory, cardiovascular, and neurological diseases. Although there are several advantages of N&N in healthcare, many challenges have to be conquered to increase the availability of nanotechnology products in toxicological, preclinical and clinical studies, scale-up, regulatory, and private investments.

Panorama de propriedade intelectual, transferência de tecnologia e inovação da química brasileira e a comparação com os países do BRIC

Based on Science, Technology & Innovation (ST&I) indicators, Brazil is a competitive and interesting country from the point of view of technological foreign investment. However, it is still incipient with regard to national investments, production of technological knowledge, inbound mobility of scientists and technology transfer to the productive sector. Among many other factors, global patent production is considered as an important indicator of innovation. Likewise, the balance between revenue and expenses obtained through royalties and licensing fees of technologies is also critical in mapping the diffusion and absorption of knowledge. The understanding of intellectual property and its strategic management brings a significant advantage to the economic and technological development of nations, especially in the field of chemistry, which greatly contributes to biotechnology, new materials and microelectronics - three fundamental areas for innovation in developed countries. Therefore, this article aims to map out competencies in chemistry in Brazil and evaluate science, technology and innovation indicators in the country, comparing this dynamic to the one of other BRIC members (Russia, India and China). Chemistry is the fourth biggest field of interest in Brazil based on the number of researchers registered at the governmental platform for researchers, Plataforma Lattes/CNPq, and is preceded by education, medicine and agronomy. The majority of research groups are registered in the area of materials, followed by macromolecules and polymers, pharmaceutical products and basic materials chemistry. These groups represent approximately 77% of research groups analyzed, therefore, indicating a tendency in the country. The analyses of patents in different sub-areas of chemistry reveal that non-residents file most deposits in the country, a probable reflection of the low internal intellectual property culture. Pharmaceutics and Fine Chemistry are prominent areas in the country, in line with the global trend. Among BRIC countries, China has the highest number of patents and of requests for protection in international offices. On the other hand, Brazil has the lowest number of chemical patents published at USPTO, EPO and JPO. An analysis of the transfer of technology data indicates an increase in this activity in various sub-areas of chemistry in the country. Despite the great efforts made by the country to consolidate its national innovation system, more needs to be done to put Brazil in a competitive position. In a globalized world dominated by large players, Brazil needs a lot of progress on ownership and generation of chemistry technologies to strengthen its national sovereignty. It is essential to strengthen chemical research at all levels, from elementary school to university, as an inexhaustible source of knowledge and technology that, when properly protected, may generate real public achievement and social return.

Doenças tropicais negligenciadas: uma nova era de desafios e oportunidades

In an article recently published in Química Nova, entitled "Chemistry Without Borders" ("Química Sem Fronteiras") [Pinto, A. C.; Zucco, C.; Galembeck, F.; Andrade, J. B.; Vieira, P. C. Quim. Nova 2012, 35, 2092], the authors highlighted the important aspects of science and technology with special emphasis on the field of Chemistry and its contributions toward a more prosperous Brazil of future. As a second step in that direction, this article extends the discussion of a key issue for the country in the framework of the chemistry community through the so called position papers in strategic areas. This document is a part of the contribution of the Brazilian Chemical Society to the World Science Forum to be held in Rio de Janeiro in November 2013. In this context, the present paper provides a brief discussion on neglected tropical diseases (NTDs) with emphasis on the current challenges and opportunities towards the development and evolution of the field. NTDs leads to illness, long-term disability or death, and has severe social, economic and psychological consequences for millions of men, women, and children worldwide. In most cases, the available treatments are inadequate and extremely limited in terms of efficacy and safety, leading to an urgent demand for new drugs. In addition to the traditional challenges involved in any drug discovery process, it is widely recognized that there is an innovation gap and a lack of investment for research and development (R&D) in the area of NTDs. In the last few decades, methods toward combating, eradication, prevention, and treatment of NTDs have been repeatedly emphasized in the major international agendas. Developments in these strategies and alliances have continued to have an essential impact, particularly in the area of drug discovery, both in Brazil and globally and should be encouraged and supported. Several examples of international activities dedicated to the reduction of the devastating global impact of NTDs can be provided. Despite the beneficial developments in the past 30 years, NTDs continue to devastate poor communities in remote and vulnerable areas, in large part, due to market failures and public policies. Recent studies have shown that among 756 new drugs approved between 2000 and 2011, only four new chemical entities (NCEs) were identified for the treatment of malaria, while none were developed against NTDs or tuberculosis. Furthermore, only 1.4% of approximately 150,000 clinical trials were registered for neglected diseases, with a smaller number of trials for NCEs. Establishment and strengthening of global strategies involving the triad "government-academia-industry" is fundamental to the success in R&D of new drugs for NTDs. National and international public-private initiatives that aim to create, encourage, and invest in R&D projects have been implemented and therefore are of utmost importance to successfully integrate Brazil into this new paradigm. It is essential to lay the foundation for mechanisms that will intensify investments in infrastructure, training, and qualification of personnel with an ultimate strategic vision that foresees continuity. Our research group has made significant contributions to the development of this field with the goal of forging new frontiers while tackling both current and future challenges that include indispensable elements such as innovation and integration.

A pesquisa em Ensino de Química como área estratégica para o desenvolvimento da Química

This paper presents an overview of the development of chemical education as a research area and some of its contributions to society. Although science education is a relatively recent area of research, it went through an expressive development in the last decades. As in the whole world, in Brazil also such development is attested by the expressive number of scientific societies, specialized journals, and meetings with growing attendance in the areas of science education in general and chemical education in particular. Following are the main contributions of research in science education related to chemistry teaching: adoption of teaching-learning principles in chemistry education; contextualization of chemical knowledge; interdisciplinary approach to chemistry teaching; use of the history of science for the definition of contents and for the design of curricula and teaching tools; development of specific disciplines for the initial and in-service training of chemistry teachers; publication of innovative chemistry textbooks by university-based research groups; elaboration of official guidelines for high-school level; and evaluation of chemistry textbooks to be distributed to high-school students by the Brazilian government. In spite of a positive impact of such initiatives, science education in Brazil still faces many problems, as indicated by poor results in international evaluations (such as the Program for International Student Assessment). However, changes in such a scenario depend less on the research in chemical education than on the much-needed governmental initiatives aiming at the improvement of both attractiveness of teaching career and structural conditions of public schools. In conclusion, new government investments in education are necessary for continuing the development of chemistry; moreover, scientific societies and decision makers in educational policies should take into consideration the contributions originated from the chemical education research area.

Uuden valmistusteknologian käyttöönottoprosessin kuvaaminen

Raskaassa teollisuudessa perinteisten valmistusmenetelmien kehitys vaatii uusiin valmistusteknologioihin investoimista ja niiden käyttöönottoa. Valmistusteknologioiden käyttöönottoja johdetaan yrityksissä useimmiten yksittäisinä projekteina. Tämän tutkimuksen tarkoituksena on selvittää, voidaanko valmistusteknologian käyttöönotoissa tunnistaa yhteisiä piirteitä ja onko niihin mahdollista soveltaa prosessijohtamisen menetelmiä. Tutkimuksen taustan muodostaa kirjallisuusselvitys aiemmin julkaistuista aihepiiriin liittyvistä tutkimuksista. Tärkeimmät teoreettiset viitekehykset aiemmista tutkimuksista ovat Taskisen julkaisu tuotantoprosessin muutoksen vaiheista sekä muutoksen mittaristosta, sekä Carillon ja Gaimonin tutkimus valmistusprosessin muutostavoitteista sekä niiden resursoinnista. Lisäksi prosessijohtamisen käsitteet ja yleisimmät prosessien kuvaamisen standardimenetelmät esiteltiin. Työssä tutustutaan suomalaisessa raskaan teollisuuden kasvuyrityksessä tehtyihin valmistusteknologian käyttöönottojen suorituksiin ja niissä havaittuihin kehityskohteisiin. Näiden kehityskohteiden ja teoreettisten viitekehysten perusteella luotiin prosessimalli valmistusteknologian käyttöönotosta. Tutkimuksessa havaittiin, että uuden valmistusteknologian käyttöönotto noudattaa tuotantoprosessiin tehtävien muutosten teoriaa, ja siitä voidaan tunnistaa käyttöönoton tyypistä riippumattomia toistuvia vaiheita. Nämä vaiheet ja toiminnot on mahdollista kuvata prosessiksi, jota voidaan kehittää käyttöönottojen suorituksesta saatujen kokemusten ja mittaustuloksien avulla.

Suorat ulkomaiset investoinnit Baltiaan

Tässä kandidaatintyössä tavoitteenamme oli selvittää Baltian alueen suosion syitä investoinnin kohteena. Aluksi selvitimme mitä suorat ulkomaiset investoinnit tarkoittavat ja tarkastelimme investointien hyötyjä sekä investoivalle taholle että investoinnin kohteena olevalle valtiolle. Näiden tutkimusten valossa pystyimme tarkastelemaan investointeja Baltian alueelle. Kuvasimme Baltian maiden investointiympäristöä tietyillä makrotalouden tunnusluvuilla sekä analysoimalla maiden korruptiotilannetta. Lisäksi tutkimme kansainvälisten organisaatioiden tekemiä listauksia liiketoiminnan harjoittamisen ja kilpailukyvyn suhteen. Vertasimme toteutuneita investointilukuja investointiympäristön houkuttelevuuteen eri mittareilla mitattuna, jolloin pystyimme päättelemään, selittävätkö käyttämämme mittarit maihin tehtyjen suorien ulkomaisten investointien määrää. Pyrimme myös selvittämään, mitkä maat ja toimialat ovat olleet Baltian suorien ulkomaisten investointien lähteenä. Lopuksi pohdimme Baltian maiden tulevaisuutta suorien investointien kohteena käytössä olevien ennusteiden perusteella.

Innovative Culture – Searching for Innovativeness in a Construction Company

The purpose of the thesis is to study innovativeness in a context of the construction industry especially the front-end of the innovation process. The construction industry is often considered an old-fashioned manufacturing industry. Innovations and innovativeness are rarely linked to the industry. The construction industry, as well as other industries in Finland, is facing challenges such as productivity, the climate change and internationalization. The meaning of innovations is greater than ever in continuously changing markets, for standing out from competitors or increasing the competitiveness. Traditional production methods, tight building regulations, unique buildings, one-of-a-kind project organizations and highlighting the cheapest price in building contracts are particular challenges in the construction industry. The research questions of the thesis were: - What kind of factors shift the existing company culture towards innovativeness? - What are the phases of the front-end of the innovation process? - What kind of tools and methods enable managing the front-end of the innovation process? The theoretical part of the thesis bases on the literature review. The research methodology of the empirical part was the action research and qualitative approach. Empirical data was collected by the theme interviews from three companies. The results were practical methods and experiences from innovation activities of the companies. The results of the thesis can be clarified as follows: enhancement of the innovation activities requires support and commitment of the top management, innovative culture and innovation strategy. Innovativeness can be promoted by systematical methods for example collecting ideas from employees. Controlling and managing the front-end phase is essential to succeeding. Despite that managing the front-end is the most challenging part of the innovation process, development and management of that save companies’ money, resources and prevents useless investments. Further clarification and studies are needed to find out furthermore functional tools and methods to manage innovations and implementing them to the culture of the companies.

Keskitetyn lämmöntuotannon kehittämismahdollisuudet Lahden seudulla ilmastonmuutoksen näkökulmasta

Tämä diplomityö on tehty Aalto yliopiston Teknillisen korkeakoulun Lahden keskuksen IMMU-hankkeeseen. Teoriaosassa tarkastellaan kaukolämmityksen nykytilannetta ja sen tulevai-suuteen vaikuttavia tekijöitä. Työssä on tarkasteltu Lahti Energia Oy:n Kymijärven voimalaitosalueen kehittämismahdollisuuksia vuosina 2012 ja 2016. Vertailukohtana käytetään nykytilannetta vuoden 2009 tiedoilla. Työssä on selvitetty voimalaitosalueen elinkaaren aikaisia kasvihuonekaasupäästöjä ja niiden muutoksia mahdollisten uusien voimalaitosinvestointien myötä. Vuonna 2012 alueelle rakennetaan kiinteää polttoainetta käyttävä kaasutusvoimalaitos jolloin nykyisen laitoksen käyttö ja samalla kivihiilen käyttö vähenee huomattavasti. Tässä työssä vuoden 2016 skenaariossa alueelle ajatellaan rakennettavan kolmas voimalaitos, maakaasukäyttöinen kaasukombiturbiini. Tarkasteluissa energiantuotantomäärien oletetaan pysyvän nykytilanteen suuruisina. Työssä tarkasteltujen skenaarioiden perusteella alueen yhdistetyn kaukolämmön- ja sähköntuotannon (CHP) päästöjä voitaisiin vähentää vuonna 2012 noin 20 % ja vuonna 2016 noin 30 % nykytilanteesta. Esitettyjen investointien riskinä on sopivan polttoaineen saatavuus ja riittävyys. Lisäksi työssä tarkasteltiin kaasutusvoimalaitoksen ja kaasukombiturbiinin takaisinmaksuaikoja. Kierrätyspolttoaineen hinnan kallistuminen hinnasta 5 €/MWh hintaan 15 €/MWh vaikutti kaasutusvoimalaitoksen takaisinmaksuaikaan yhdeksällä vuodella. Kaasukombiturbiinin takaisinmaksuaika piteni tämän hetkiseen maakaasun hintaan 27 €/MWh verrattuna päästöoikeuden lisäkustannus 6 €/MWh huomioiden kahdeksan vuotta. Takaisinmaksuaikaan vaikuttaa muun muassa polttoaineen hinta ja laitoksen huipunkäyttöaika.
