Pharmaceutical and Industrial Traits in Genetically Modified Crops: Co-existence with Conventional Agriculture, August 2006

This paper discusses the implications of using genetically modified crops to biomanufacture pharmaceuticals and industrial compounds from the perspective of their co-existence with conventional agriculture. Such plant-made pharmaceuticals and plantmade industrial products rely on exciting scientific and technological breakthroughs and promise new opportunities for the agricultural sector, but they also entail novel risks. The management of the externalities and of the possible unintended economic effects that arise in this context is critical and poses difficult questions for regulators.

Políticas productivas y competitividad industrial: El caso de Argentina y Brasil

This article aims, on the one hand, to analyze the increase of productive asymmetries between Argentina and Brazil that have been evidencing during the last two decades, and are currently reveled in the structural trade deficit of industrial products that affects Argentina in the bilateral relationship. On the other hand, it intends to contribute to understanding the roots of these asymmetries based on the differences in the public policies implemented by both countries during the period extending from the implementation of the Mercosur, in the early 1990s, until 2008. The focus is set on the technological pattern of industrial production and trade structures, considering a non neutral impact over the long term development.

Lifecycle assessment of fuel ethanol from sugarcane in Brazil

This paper presents the lifecycle assessment (LCA) of fuel ethanol, as 100% of the vehicle fuel, from sugarcane in Brazil. The functional unit is 10,000 km run in an urban area by a car with a 1,600-cm(3) engine running on fuel hydrated ethanol, and the resulting reference flow is 1,000 kg of ethanol. The product system includes agricultural and industrial activities, distribution, cogeneration of electricity and steam, ethanol use during car driving, and industrial by-products recycling to irrigate sugarcane fields. The use of sugarcane by the ethanol agribusiness is one of the foremost financial resources for the economy of the Brazilian rural area, which occupies extensive areas and provides far-reaching potentials for renewable fuel production. But, there are environmental impacts during the fuel ethanol lifecycle, which this paper intents to analyze, including addressing the main activities responsible for such impacts and indicating some suggestions to minimize the impacts. This study is classified as an applied quantitative research, and the technical procedure to achieve the exploratory goal is based on bibliographic revision, documental research, primary data collection, and study cases at sugarcane farms and fuel ethanol industries in the northeast of SA o pound Paulo State, Brazil. The methodological structure for this LCA study is in agreement with the International Standardization Organization, and the method used is the Environmental Design of Industrial Products. The lifecycle impact assessment (LCIA) covers the following emission-related impact categories: global warming, ozone formation, acidification, nutrient enrichment, ecotoxicity, and human toxicity. The results of the fuel ethanol LCI demonstrate that even though alcohol is considered a renewable fuel because it comes from biomass (sugarcane), it uses a high quantity and diversity of nonrenewable resources over its lifecycle. The input of renewable resources is also high mainly because of the water consumption in the industrial phases, due to the sugarcane washing process. During the lifecycle of alcohol, there is a surplus of electric energy due to the cogeneration activity. Another focus point is the quantity of emissions to the atmosphere and the diversity of the substances emitted. Harvesting is the unit process that contributes most to global warming. For photochemical ozone formation, harvesting is also the activity with the strongest contributions due to the burning in harvesting and the emissions from using diesel fuel. The acidification impact potential is mostly due to the NOx emitted by the combustion of ethanol during use, on account of the sulfuric acid use in the industrial process and because of the NOx emitted by the burning in harvesting. The main consequence of the intensive use of fertilizers to the field is the high nutrient enrichment impact potential associated with this activity. The main contributions to the ecotoxicity impact potential come from chemical applications during crop growth. The activity that presents the highest impact potential for human toxicity (HT) via air and via soil is harvesting. Via water, HT potential is high in harvesting due to lubricant use on the machines. The normalization results indicate that nutrient enrichment, acidification, and human toxicity via air and via water are the most significant impact potentials for the lifecycle of fuel ethanol. The fuel ethanol lifecycle contributes negatively to all the impact potentials analyzed: global warming, ozone formation, acidification, nutrient enrichment, ecotoxicity, and human toxicity. Concerning energy consumption, it consumes less energy than its own production largely because of the electricity cogeneration system, but this process is highly dependent on water. The main causes for the biggest impact potential indicated by the normalization is the nutrient application, the burning in harvesting and the use of diesel fuel. The recommendations for the ethanol lifecycle are: harvesting the sugarcane without burning; more environmentally benign agricultural practices; renewable fuel rather than diesel; not washing sugarcane and implementing water recycling systems during the industrial processing; and improving the system of gases emissions control during the use of ethanol in cars, mainly for NOx. Other studies on the fuel ethanol from sugarcane may analyze in more details the social aspects, the biodiversity, and the land use impact.

Australian import managers' purchasing decision behaviour: An empirical study

Reports a pilot study of the relative importance of import decision variables as rated by Australian managers. A systematic sample qi 104 Australian managers representing different companies participated in the study. Australian importers rated product quality as the most important variable when importing products from overseas followed by long-term suppliers' dependability, product style/feature, price, and timely delivery. Australian managers who import consumer products find the domestic import duties and tariffs to be more important than did those who import industrial products. Larger volume importers regard the product brand name reputation to be more important than did those who import smaller volumes.

Mechanisms underlying cytotoxicity induced by engineered nanomaterials: a review of in vitro studies

Engineered nanomaterials are emerging functional materials with technologically interesting properties and a wide range of promising applications, such as drug delivery devices, medical imaging and diagnostics, and various other industrial products. However, concerns have been expressed about the risks of such materials and whether they can cause adverse effects. Studies of the potential hazards of nanomaterials have been widely performed using cell models and a range of in vitro approaches. In the present review, we provide a comprehensive and critical literature overview on current in vitro toxicity test methods that have been applied to determine the mechanisms underlying the cytotoxic effects induced by the nanostructures. The small size, surface charge, hydrophobicity and high adsorption capacity of nanomaterial allow for specific interactions within cell membrane and subcellular organelles, which in turn could lead to cytotoxicity through a range of different mechanisms. Finally, aggregating the given information on the relationships of nanomaterial cytotoxic responses with an understanding of its structure and physicochemical properties may promote the design of biologically safe nanostructures.

Mekaanisen puunjalostuksen markkinakartoitus: Koivusahatavaran ja -puolijalosteiden markkinat Euroopassa

Tutkimuksen tavoitteena oli kartoittaa koivusahatavaran ja -puolijalosteiden potentiaalisia vientikohdemaita EU-maissa ja Norjassa. Tarkastelun kohteena olivat koivutuotteiden markkinapotentiaali ja kysyntä sekä puutuotteiden markkinointikanavavaihtoehdot Euroopan puutuotemarkkinoilla. Tutkimuksen teoreettisena lähtökohtana oli tarkastella, kuinka markkinointitutkimuksen avulla kartoitetaan tuotantohyödykemarkkinoita, miten määritetään tuotantohyödykkeen markkinapotentiaali ja kysyntä sekä mitä markkinointikanavavaihtoehtoja puutuotteita valmistavalla yrityksellä on vientimarkkinoille lähdettäessä. Empiirisessä osassa selvitettiin sekä kvantitatiivista että kvalitatiivista tietoa Euroopan puutuotemarkkinoista. Lehtipuu- ja koivusahatavaran vienti-, tuonti- ja tuotantotilastojen pohjalta tarkasteltiin koivun suurimpia vientikohdemaita ja arvioitiin kysyntää tulevaisuudessa. Tämän lisäksi puutuotteiden toimialaorganisaatioiden, asiantuntijoiden, puutuotteita valmistavien yritysten ja maahantuojien haastattelujen avulla muodostettiin kokonaiskuva koivusahatavaran ja -puolijalosteiden markkinapotentiaalista ja koivutuotteiden asemasta Euroopan puutuotemarkkinoilla. Koivu koettiin Euroopan puutuotemarkkinoilla kiinnostavana puulajina ja koivutuotteiden kysyntä onkin ollut viime vuosien aikana nousujohteista. Tämä johtuu suurimmaksi osaksi tällä hetkellä vallitsevasta vaaleiden puulajien trendistä. Markkinoilla menestyminen riippuu kuitenkin siitä, kuinka hyvin koivun tarjoaja pystyy vastaamaan asiakkaiden tuotteelle asettamiin vaatimuksiin.

Asiakaslähtöisyyden huomioiminen teollisuusyritysten hinnanasetannassa

Tämän työn tarkoituksena oli tutkia tuotteen hinnanasetantaa teollisuusyrityksissä asiakaslähtöisyyden näkökulmasta. Hinnoittelumenetelmiä ja hinnoittelustrategioita tutkimalla pyrittiin etsimään ne tekijät, jotka tulisi ottaa huomioon suunniteltaessa arvoperusteista hinnoittelumenetelmää. Tutkimus on toteutettu yhden tapauksen kvalitatiivisena tutkimuksena ja se suoritettiin teollisuuden tuotteita valmistavassa yrityksessä. Haastattelut tehtiin vuoden 2008 alussa yksilöhaastatteluina käyttäen pohjana puolistrukturoitua haastattelurunkoa. Tutkimustulokset osoittavat, että kohdeyrityksestä voidaan löytää ne tekijät, jotka teorian mukaan tulisi ottaa huomioon suunniteltaessa asiakkaan arvoon perustuvaa hinnoittelua. Tutkimustulosten mukaan asiakaslähtöisyyttä tarkastellaan asiakkaan näkökulmasta. Asiakas määrittelee näin ollen itse tuotteista kokemansa/havaitsemansa arvon. Tuotteen arvon onnistunut argumentointi asiakkaalle nähdään myös tärkeänä kilpailutekijänä.

Maritime transportation in the Gulf of Finland in 2007 and in 2015

The Gulf of Finland is said to be one of the densest operated sea areas in the world. It is a shallow and economically vulnerable sea area with dense passenger and cargo traffic of which petroleum transports have a share of over 50 %. The winter conditions add to the risks of maritime traffic in the Gulf of Finland. It is widely believed that the growth of maritime transportation will continue also in the future. The Gulf of Finland is surrounded by three very different national economies with, different maritime transportation structures. Finland is a country of high GDP/per capita with a diversified economic structure. The number of ports is large and the maritime transportation consists of many types of cargoes: raw materials, industrial products, consumer goods, coal and petroleum products, and the Russian transit traffic of e.g. new cars and consumer goods. Russia is a large country with huge growth potential; in recent years, the expansion of petroleum exports has lead to a strong economic growth, which is also apparent in the growth of maritime transports. Russia has been expanding its port activities in the Gulf of Finland and it is officially aiming to transport its own imports and exports through the Russian ports in the future; now they are being transported to great extend through the Finnish, Estonian and other Baltic ports. Russia has five ports in the Gulf of Finland. Estonia has also experienced fast economic growth, but the growth has been slowing down already during the past couples of years. The size of its economy is small compared to Russia, which means the transported tonnes cannot be very massive. However, relatively large amounts of the Russian petroleum exports have been transported through the Estonian ports. The future of the Russian transit traffic in Estonia looks nevertheless uncertain and it remains to be seen how it will develop and if Estonia is able to find replacing cargoes if the Russian transit traffic will come to an end in the Estonian ports. Estonia’s own import and export consists of forestry products, metals or other raw materials and consumer goods. Estonia has many ports on the shores of the Gulf of Finland, but the port of Tallinn dominates the cargo volumes. In 2007, 263 M tonnes of cargoes were transported in the maritime traffic in the Gulf of Finland, of which the share of petroleum products was 56 %. 23 % of the cargoes were loaded or unloaded in the Finnish ports, 60 % in the Russian ports and 17 % in the Estonian ports. The largest ports were Primorsk (74.2 M tonnes) St. Petersburg (59.5 M tonnes), Tallinn (35.9 M tonnes), Sköldvik (19.8 M tonnes), Vysotsk (16.5 M tonnes) and Helsinki (13.4 M) tonnes. Approximately 53 600 ship calls were made in the ports of the Gulf of Finland. The densest traffic was found in the ports of St. Petersburg (14 651 ship calls), Helsinki (11 727 ship calls) and Tallinn (10 614 ship calls) in 2007. The transportation scenarios are usually based on the assumption that the amount of transports follows the development of the economy, although also other factors influence the development of transportation, e.g. government policy, environmental aspects, and social and behavioural trends. The relationship between the development of transportation and the economy is usually analyzed in terms of the development of GDP and trade. When the GDP grows to a certain level, especially the international transports increase because countries of high GDP produce, consume and thus transport more. An effective transportation system is also a precondition for the economic development. In this study, the following factors were taken into consideration when formulating the future scenarios: maritime transportation in the Gulf of Finland 2007, economic development, development of key industries, development of infrastructure and environmental aspects in relation to maritime transportation. The basic starting points for the three alternative scenarios were: • the slow growth scenario: economic recession • the average growth scenario: economy will recover quickly from current instability • the strong growth scenario: the most optimistic views on development will realize According to the slow growth scenario, the total tonnes for the maritime transportation in the Gulf of Finland would be 322.4 M tonnes in 2015, which would mean a growth of 23 % compared to 2007. In the average growth scenario, the total tonnes were estimated to be 431.6 M tonnes – a growth of 64 %, and in the strong growth scenario 507.2 M tonnes – a growth of 93%. These tonnes were further divided into petroleum products and other cargoes by country, into export, import and domestic traffic by country, and between the ports. For petroleum products, the share of crude oil and oil products was estimated and the number of tanker calls in 2015 was calculated for each scenario. However, the future development of maritime transportation in the GoF is dependent on so many societal and economic variables that it is not realistic to predict one exact point estimate value for the cargo tonnes for a certain scenario. Plenty of uncertainty is related both to the degree in which the scenario will come true as well as to the cause-effect relations between the different variables. For these reasons, probability distributions for each scenario were formulated by an expert group. As a result, a range for the total tonnes of each scenario was formulated and they are as follows: the slow growth scenario: 280.8 – 363 M tonnes (expectation value 322.4 M tonnes)

Computational Techniques for Spectral Image Analysis

Multispectral images are becoming more common in the field of remote sensing, computer vision, and industrial applications. Due to the high accuracy of the multispectral information, it can be used as an important quality factor in the inspection of industrial products. Recently, the development on multispectral imaging systems and the computational analysis on the multispectral images have been the focus of a growing interest. In this thesis, three areas of multispectral image analysis are considered. First, a method for analyzing multispectral textured images was developed. The method is based on a spectral cooccurrence matrix, which contains information of the joint distribution of spectral classes in a spectral domain. Next, a procedure for estimating the illumination spectrum of the color images was developed. Proposed method can be used, for example, in color constancy, color correction, and in the content based search from color image databases. Finally, color filters for the optical pattern recognition were designed, and a prototype of a spectral vision system was constructed. The spectral vision system can be used to acquire a low dimensional component image set for the two dimensional spectral image reconstruction. The data obtained by the spectral vision system is small and therefore convenient for storing and transmitting a spectral image.

LOW COST ANALYZER FOR THE DETERMINATION OF PHOSPHORUS BASED ON OPEN-SOURCE HARDWARE AND PULSED FLOWS

The need for automated analyzers for industrial and environmental samples has triggered the research for new and cost-effective strategies of automation and control of analytical systems. The widespread availability of open-source hardware together with novel analytical methods based on pulsed flows have opened the possibility of implementing standalone automated analytical systems at low cost. Among the areas that can benefit from this approach are the analysis of industrial products and effluents and environmental analysis. In this work, a multi-pumping flow system is proposed for the determination of phosphorus in effluents and polluted water samples. The system employs photometric detection based on the formation of molybdovanadophosphoric acid, and the fluidic circuit is built using three solenoid micropumps. The detection is implemented with a low cost LED-photodiode photometric detection system and the whole system is controlled by an open-source Arduino Uno microcontroller board. The optimization of the timing to ensure the color development and the pumping cycle is discussed for the proposed implementation. Experimental results to evaluate the system behavior are presented verifying a linear relationship between the relative absorbance and the phosphorus concentrations for levels as high as 50 mg L-1.

Kalsiumkarbonaatin kemiallisfysikaalinen käsittely ja materiaalin karakterisointi

Saostettua karbonaattia voidaan käyttää useiden eri teollisuuksien tuotteissa. Pääosin saostettua kalsiumkarbonaattia kuitenkin käytetään paperin, maalien, muovien sekä elintarviketuotteiden täyteaineena. Koska monet käyttökohteet vaativat saostetulta kalsiumkarbonaatilta tiettyjä puhtausvaatimuksia, sen koostumuksen tutkiminen on suuren kiinnostuksen kohteena. Työn perimmäisenä tarkoituksena on ollut määrittää saostetun kalsiumkarbonaatin kemiallinen koostumus ja selvittää, vaikuttavatko materiaalin kemiallisfysikaalinen modifiointi sen ominaisuuksiin. Kirjallisuusosassa käsitellään yleisesti kalsiumkarbonaattimateriaaleja, saostetun kalsiumkarbonaatin valmistusmenetelmiä ja vastaavanlaisen materiaalin esikäsittelymenetelmiä. Lisäksi tarkastellaan erilaisia analyysimenetelmiä, joita voidaan käyttää kiinteiden epäorgaanisten tai mineraalinäytteiden kemiallisen koostumuksen sekä fysikaalisten ja kemiallisten reaktioiden määrittämiseen. Kokeellisessa osassa tutkittiin käsittelemättömiä saostettuja kalsiumkarbonaattinäytteiden ominaisuuksia ja kemiallista koostumusta erilaisilla alkuaine-, ioni-/spesies- sekä pyrolyysimittauksilla. Näytteitä modifioitiin lämmityksen ja jauhatuksen avulla. Modifioinnin vaikutusta näytteiden kemiallisiin koostumuksiin tutkittiin vertailemalla tuloksia käsittelemättömien näytteiden antamiin tuloksiin. Tutkimus osoitti, että näytteiden lämpökäsittelyllä ei ollut lähes ollenkaan vaikutusta näytteiden kemialliseen koostumukseen. Toisin osoitti näytteiden jauhatus, joka laski ammoniumin pitoisuutta näytteissä. Laitetekniikkaa käytettäessä kapillaarielektroforeesi, ionikromatografi, ICP-AES ja SEM (FTIR) antoivat luotettavinta tietoa näytteiden kemiallisista koostumuksista. Näytteiden fysikaalisia ja kemiallisia reaktioita voitiin havainnollistaa parhaiten käyttäen STA-QMS -laitetta.

Biopohjaiset polymeerit dispersiopäällystyksessä

Työn aiheena oli tehdä muotoiltavissa oleva rasvankestävä pakkauskartonki. Polymeeridispersiopäällystettyjä pakkauskartonkeja käytetään kertakäyttöisissä tuotteissa kuten vuoissa, kupeissa ja lautasissa. Tuotteiden on kestettävä rasvaa niiden lopputarkoituksen mukaisesti. Pakkausala jatkaa vuosittaista kasvuaan vauhdilla. Uusia kierrätettäviä biopohjaisia ja luonnolle ystävällisempiä pakkaustuotteita on kehitettävä kasvun tyydyttämiseksi. Biopohjaiset pakkaustuotteet ovat mahdollisia ratkaisuja ympäristöön kohdistuvien ongelmien vähentämiseksi ja öljypohjaisten raaka-aineiden korvaajiksi. Diplomityön teoriaosuudessa keskityttiin dispersiopäällystyksessä käytettyihin biopolymeereihin ja niiden toimivuuteen suojaavina kalvoina. Teoriaosuudessa käsiteltiin myös rasvankestoa ja rasvankestävien tuotteiden materiaaliominaisuuksia. Kirjallisuuden perusteella havaittiin luonnonpolymeerien alhaisen kuiva-ainepitoisuuden ja korkean päällystemäärätarpeen muodostamat haasteet dispersiopäällystyksessä. Pohjakartongin karheudella ja tiiveydellä sekä suojaavan polymeerin kalvon rakenteella huomattiin olevan suuri merkitys rasvankeston saavuttamiseksi. Kokeellinen osa jakautui kolmeen osakokonaisuuteen: laboratoriokokeisiin, esipilotointiin ja varsinaiseen pilot-koeajoon. Esikokeiden perusteella suojaavat kalvot, joiden raaka-aineena käytettiin biopohjaisia dispersiopolymeerejä, antoivat riittäviä rasvankesto-ominaisuuksia, mutta eivät kestäneet konvertointia. Pienellä synteettisten polymeerien lisäyksellä pystyttiin parantamaan päällystettyjen kartonkien rasvankestoa sekä konvertoitavuutta. Pilot-koeajonäytteiden testaustulokset tukivat esikokeissa tehtyjä havaintoja. Tämän työn perusteella kohtuullinen lisäysmäärä synteettistä polymeeriä voi parantaa merkittävästi biopohjaisen suojaavan kalvon antamaa rasvankestoa sekä päällystetyn kartongin konvertoitavuutta.

Chemical characterization of the flour of peel and seed from two papaya cultivars

Papaya is among the currently most important tropical fruits grown in Brazil and in the world. The fruit is mainly consumed fresh although it offers many industrial products. The processing of this fruit, as well as its fresh consumption, results in large amounts of waste, such as peels and seeds. Papaya consumption is one of the causes of significant loss of food value; therefore, new aspects on the use of its waste as by-products, or in the production of food additives, or even the incorporation of its flour in food have aroused great interest because these are products of high nutritional value, and their use may be economically viable. The objective of this study was to produce and characterize peel and seed flours from two papaya cultivars (Havai and Calimosa) for their chemical constituents focusing on possible use in foods. The proximate and mineral composition, titratable acidity, soluble solids, pH, contents of vitamin C, and phenolic compounds were determined. According to the results obtained, the papaya peel and seed flours had high contents of protein and fiber and therefore can be used as alternative sources of nutrients and can also be added in foods avoiding waste and adding value to the fruit.

Näkökulmia 3D-tulostuksen opetukseen ja koulutukseen

Additive manufacturing, or 3D printing, is globally one of most interesting area in developing of manufacturing technologies. This technology is suitable for fabrication off industrial products and it interests actors in fields of computer sciences, economics, medical sciences and design&arts. Additive manufacturing is often referred as third industrial revolution: first revolution was invention of steam engines in 18th century and second was industrial revolution started by Henry Ford in 1920s. Companies should be able to test suitability of their products for additive manufacturing and 3D printing but also how much better products could be when products are totally re-designed so that all potential of this new technology can be utilized. This is where education has its importance; new generations who enter working life should be educated to know of additive manufacturing and 3D printing, its advantages but also of it limits. There has to be also possibility to educate industry and people already working there, so that industrial implementation could be done successfully. This is especially very valid for Finland. Education is strongly needed so that Finnish industry can maintain its competence in global markets. Role of education is extremely important when a new technology is industrially implemented. Additive manufacturing and 3D printing offers freedom to design new products, production and generally ways of doing things. Development, planning and execution of education for additive manufacturing and 3D printing is challenging as this area develops very fast. New innovations are coming almost every month. Planning of education for additive manufacturing and 3D printing requires collection pieces of data from various of sources. Additive manufacturing and 3D printing industry and its development has to be followed frequently, and material for additive manufacturing and 3D printing has to be renewed frequently.

A industrialização da pauta de exportação brasileira entre 1964 e 1974: novos dados e índices para o comércio exterior brasileiro do período

This paper analyses the effects on Brazil's trade indices of the rising share of industrial products in Brazil's exports in the period from 1964 to 1974. New price and quantity indices of Fisher for Brazil's exports and imports of industrial and non-industrial goods have been especially constructed for this period, in order to obtain methodologically consistent series of indexes from 1964 to 2005. The market-share-constant model was applied to analyze the effects of different groups of products on Brazil's export revenues between 1964 and 1974.
