Comparative lifecycle assessment on organic and conventional carrots – case: Carrots from South-Savo and imported carrots from Italy

Organic farming is perceived to be an environmental friendly method of food production, thus assumed to be an alternative means of minimizing food-based environmental footprints. However, lower yield and unproductive years in organic crop rotation raise questions of whether it is really an environmentally friendly farming practice. Thus, the aim of this thesis was to examine the carbon footprint and energy demands of organic carrots cultivated and sold in South-Savo, Finland and compare them with those of local and imported conventional carrots using lifecycle assessment (LCA) as a method. From the investigation, it was found that organic carrots produced in South-Savo have the lowest GHG emissions and energy demand. The GHG emissions of local organic, local conventional and imported conventional carrots were found to be 4g CO2 eq. kgcarrots-1, 142g CO2 eq. kgcarrots-1 and 280 g CO2 eq. kgcarrots-1, respectively. On the other hand, energy demand for those carrots was found to be 1,33 MJ, 1,88 MJ and 3,68 MJ kgcarrots-1. Furthermore, it was also found that local organic carrots would have approximately similar GHG emissions as conventional counterpart if soil carbon stock change was excluded from the study.

Vuosina 1995-1999 myönnettyjen yritystukien vaikuttavuus Etelä-Savossa

Tutkimuksen tavoitteena oli arvioida yritystukien vaikuttavuutta Etelä-Savon metalli- ja puuteollisuuden pienten ja keskisuurten yritysten yleisen kehityksen sekä tuille Suomen laissa ja Euroopan unionin rakennepolitiikassa asetettujen tavoitteiden näkökulmasta. Tuettujen yritysten kehitystä verrattiin ensin muiden Etelä-Savon puu- ja metalliteollisuusyritysten kehitykseen tilastotietojen avulla, minkä jälkeen vaikuttavuuden arviointia syvennettiin haastattelemalla tukea saaneiden yritysten avainhenkilöitä. Arviointi osoitti, että tuella on saatu Etelä-Savossa aikaan samanlaisia vaikutuksia kuin muuallakin Suomessa. Yritystukien avulla voidaan pääasiassa nopeuttaa yritysten hankkeiden toteutusta ja parantaa hankkeiden laatua. Tämä tukien hankkeisiin tuoma lisäarvo ilmenee tuettujen yritysten keskimääräistä voimakkaampana kehityksenä. Kokonaisuutena yritystukijärjestelmä toimii hyvin ja sen avulla voidaan saavuttaa Suomen lain ja Euroopan unionin rakennepolitiikan yritystuille asettamia tavoitteita. Keskeisin tukijärjestelmän kehittämiskohde liittyy tukien kohdistamiseen. Yritystuet pitäisi entistä tehokkaammin pystyä ohjaamaan kehittymiskelpoisille yrityksille, joille tuki on hankkeen toteuttamisen ehdoton edellytys.

Etelä-Savon energiatase 2006

The aim of this thesis is to create the energy balance from county of South Savo and 20 municipalities comprising the year 2006. The energy balance is restricted to county and municipality borders. Purpose of energy balance is to clarify the present state of energy supply and present information for future decisions. The main objectives for the future are e.g. replacing oil with renewable energy sources and exploiting the forest reserves of South Savo more effectively. Today South Savo is known as being one of the forerunners in use of renewable energy. The growing demand for energy is in South Savo mostly covered with renewable energy sources such as forest chips. The initial data for this thesis is gathered from local energy companies and energy producers. This thesis also exploits formerly made energy balances, publications and statistic from different organisations. The literature study of thesis begins with the basic information about South Savo and energy sources used in the year 2006. Following the thesis includes the energy balance consisting of primary energy sources and consumption of energy. Rest of the thesis includes facts about carbon dioxide emissions, future energy sources and conclusions of results, reliability and expected use of this thesis. Results of this thesis define well the present state of South Savo and are in line with county goals. The results will be used as an aid for policy-making and for considering the condition of current energy supply in South Savo. The method of doing this energy balance can be adapted for other counties as well.

Naisyrittäjyys ja sen edistäminen Etelä-Savon maaseutualueilla naisyrittäjien näkökulmasta

The goal of this research was to establish the development of the female entrepreneurship in rural areas of South Savo. The main problem was approached discussing female entrepreneurship and characteristics of women-owned enterprises theoretically. Also the rural areas as operational environment and development of female entrepreneurship were examined. The empirical part was implemented as an interview study by interviewing twelve rural female entrepreneurs from South Savo. The main thing should be taken into account improving female entrepreneurship is motivation and encouraging of female entrepreneurs. Female entrepreneurs feel that own municipality is the nearest public actor to develop small entrepreneurship in rural areas. Municipalities should be taken small enterprises even more into consideration when developing entrepreneurship in rural areas. Co-operation with other enterprises and interest groups was considered as one of the most important things in the development of entrepreneurship.

Juvan kunnan jätevedenpuhdistamon ympäristöasioiden parantaminen

Diplomityö on osa Mikkelin ammattikorkeakoulun YTI:ssä vuosina 2005 - 2008 toteutettua ”Yritysten ympäristöriskit” EU-osarahoitteista hanketta. Työn tarkoituksena oli tunnistaa, arvioida ja luokittaa Etelä-Savossa, Juvalla toimivan yhdyskuntajätevedenpuhdistamon ympäristöriskit sekä antaa neuvoja löytyneiden riskien hallintaan. Jätevedenpuhdistamon toiminnasta syntyvät mahdolliset ympäristöriskitekijät tunnistettiin kirjallisuusselvitysten sekä haastattelujen avulla. Riskien tunnistamisen jälkeen riskien kartoittamiseen, arviointiin ja luokittamiseen käytettiin osia eri riskianalyysimenetelmistä. Riskit jaettiin viiteen eri riskiluokkaan; vakavasta riskistä merkityksettömään riskiin. Juvan kunnan jätevedenpuhdistamolla esiintyi neljän pienimmän riskiluokan riskejä, ja vakavia riskejä ei kartoituksessa tullut esille lainkaan. Riskejä arvioitiin niin sanotuissa normaalioloissa. Merkittävin yksittäinen riskitekijä jätevedenpuhdistamolla oli haitallisen tai poikkeavan aineen kulkeutuminen jäteveden mukana puhdistamolle. Tämä voisi heikentää puhdistamon puhdistustulosta merkittävästi. Kun laitosta ajetaan ympäristöluvassa asetettujen vaatimusten mukaisesti ja alueella sijaitsevat teollisuuslaitokset noudattavat heille annettuja määräyksiä, ei Juvan jätevedenpuhdistamolta aiheudu merkittäviä päästöjä maa-perään tai pohjavesiin.

Energiapuuta Etelä-Savosta

Energiapuuta Etelä-Savosta hankkeessa tutkittiin ja kehitettiin energiapienpuun mahdollisuuksia osana suurimittakaavaista alueellista hankintaa. Energiapienpuun potentiaali suurimittakaavaisena polttoaineena on lupaava johtuen hyvästä biomassan saatavuudesta ja tarjontahalukkuudesta, korjuun teknologisesta edistyksestä ja logististen ratkaisujen monipuolisuudesta sekä käyttömäärien kasvusta. Hanke kokonaisuus sisälsi seuraavia osatutkimuksia: Etelä-Savon energiatase, metsänomistajakysely, asiantuntijahaastattelu, metsänkasvatussimulointi, metsäpolttoaineiden saatavuuslaskenta, puun kosteuden seurantatutkimus, logistiikan demonstraatioita sekä energiapuun hankintalogistiikan kustannusvertailuja. Hankkeessa käsiteltiin energiapienpuun arvoketjua metsänkasvatuksesta lopputuotteen käyttöön asti. Tutkimuksen tulokset osoittavat, että energiapienpuulla on mahdollisuudet suurimittakaavaisessa hankinnassa, kunhan toimitusketjussa panostetaan tehokkuuden ja laadun jatkuvaan parantamiseen.

Torrefioidun biohiilipelletin kirjallisuustutkimus ja koeajot pilottilaitoksessa

Tämä raportti käsittelee ”Torrefioidun biohiilipelletin laatu ja varastoitavuus” hankkeen tuloksia. Hankkeen tavoitteena oli tutkia torrefioidun biohiilipelletin prosessiteknologiaa, markkinoita ja tuotantokustannuksia kirjallisuustutkimusosiossa. Hankkeen päätutkimus keskittyi koeajoihin pilottilaitoksella, jossa valmistettiin biohiilipellettiä erilaisista puuraaka-aineista. Pilottilaitos oli perustettu Torrec Oy:n toimesta Etelä-Savon Energian Pursialan voimalaitoksen yhteyteen Mikkelissä ja sen tuotanto oli käynnistynyt kesällä 2014. Kaikki koe-erät valmistettiin vain käyttämällä sidonta-aineena lauhdevettä, jota oli tiivistynyt säiliön pohjalle torrefiointiprosessin aikana. Näin ollen erillistä lisäsidonta-aineita ei tarvittu, jolloin voidaan säästää tuotantokustannuksissa jatkossakin. Euroopan Unioni on asettanut 20 % tavoitteen uusiutuvien energioiden käytölle vuoteen 2020, josta biomassalla voidaan kattaa kaksi kolmannesta. Tutkimushankkeen tavoitteena oli metsään perustuvan bioenergiatuotannon lisääminen ja tuontienergian korvaaminen kotimaisella polttoaineella. Hankkeen tarkoituksena oli tutkimusanalyysien kautta kehittää uutta kilpailukykyistä teknologiavaihtoehtoa puupolttoaineiden hyödyntämiseksi. Torrefiointiteknologiaa ollaan kaupallistamassa ympäri Eurooppaa parasta aikaa ja uusia biohiilen tuotantolaitoksia on kehitteillä ja rakenteilla. Tutkimuksen tulokset osoittavat, että biohiilipelletillä on mahdollisuudet suurimittakaavaiseen energiantuotantoon laadun suhteen, kunhan sen käyttäminen tulee edullisemmaksi laitoksissa. Toisaalta, tämä kehitys vaatii tukimekanismeja valtion puolelta, jotta pelletit lähtisivät todella liikkeelle markkinoilla.

Compartment Syndrome After South American Rattlesnake (crotalus Durissus Terrificus) Envenomation.

In order to report the outcome of a patient who developed compartment syndrome after South American rattlesnake (Crotalus durissus terrificus) envenomation, confirmed by subfascial pressure measurement and magnetic resonance imaging (MRI). A 63-year-old male was admitted 1 h after being bitten on the right elbow by a large snake, which was not brought for identification. Physical and laboratory features upon admission revealed two fang marks, local tense swelling, paresthesia, intense local pain, hypertension, coagulopathy, and CK = 1530 U/L (RV < 170 U/L). The case was initially treated with bothropic antivenom (80 mL, intravenously), with no improvement. Evolution within 13-14 h post-bite revealed generalized myalgia, muscle weakness, palpebral ptosis, and severe rhabdomyolysis (CK = 126,160 U/L) compatible with envenoming by C. d. terrificus. The patient was then treated with crotalic antivenom (200 mL, intravenously), fluid replacement, and urine alkalinization. Twenty-four-hour post-bite MRI showed marked muscular edema in the anterior compartment of the right forearm, with a high subfascial pressure (40 mmHg) being detected 1 h later. ELISA of a blood sample obtained upon admission, before antivenom infusion, revealed a high serum concentration of C. d. terrificus venom. No fasciotomy was performed and the patient was discharged seven days later without sequelae. Snakebite by C. d. terrificus with subfascial venom injection may lead to increased intracompartmental pressure.

Characterization Of Microsatellite Markers Developed From Prosopis Rubriflora And Prosopis Ruscifolia (leguminosae - Mimosoideae), Legume Species That Are Used As Models For Genetic Diversity Studies In Chaquenian Areas Under Anthropization In South America.

Prosopis rubriflora and Prosopis ruscifolia are important species in the Chaquenian regions of Brazil. Because of the restriction and frequency of their physiognomy, they are excellent models for conservation genetics studies. The use of microsatellite markers (Simple Sequence Repeats, SSRs) has become increasingly important in recent years and has proven to be a powerful tool for both ecological and molecular studies. In this study, we present the development and characterization of 10 new markers for P. rubriflora and 13 new markers for P. ruscifolia. The genotyping was performed using 40 P. rubriflora samples and 48 P. ruscifolia samples from the Chaquenian remnants in Brazil. The polymorphism information content (PIC) of the P. rubriflora markers ranged from 0.073 to 0.791, and no null alleles or deviation from Hardy-Weinberg equilibrium (HW) were detected. The PIC values for the P. ruscifolia markers ranged from 0.289 to 0.883, but a departure from HW and null alleles were detected for certain loci; however, this departure may have resulted from anthropic activities, such as the presence of livestock, which is very common in the remnant areas. In this study, we describe novel SSR polymorphic markers that may be helpful in future genetic studies of P. rubriflora and P. ruscifolia.

Exploring Iris Colour Prediction And Ancestry Inference In Admixed Populations Of South America.

New DNA-based predictive tests for physical characteristics and inference of ancestry are highly informative tools that are being increasingly used in forensic genetic analysis. Two eye colour prediction models: a Bayesian classifier - Snipper and a multinomial logistic regression (MLR) system for the Irisplex assay, have been described for the analysis of unadmixed European populations. Since multiple SNPs in combination contribute in varying degrees to eye colour predictability in Europeans, it is likely that these predictive tests will perform in different ways amongst admixed populations that have European co-ancestry, compared to unadmixed Europeans. In this study we examined 99 individuals from two admixed South American populations comparing eye colour versus ancestry in order to reveal a direct correlation of light eye colour phenotypes with European co-ancestry in admixed individuals. Additionally, eye colour prediction following six prediction models, using varying numbers of SNPs and based on Snipper and MLR, were applied to the study populations. Furthermore, patterns of eye colour prediction have been inferred for a set of publicly available admixed and globally distributed populations from the HGDP-CEPH panel and 1000 Genomes databases with a special emphasis on admixed American populations similar to those of the study samples.

Geographical Distribution Of The Association Between El Niño South Oscillation And Dengue Fever In The Americas: A Continental Analysis Using Geographical Information System-based Techniques.

El Niño South Oscillation (ENSO) is one climatic phenomenon related to the inter-annual variability of global meteorological patterns influencing sea surface temperature and rainfall variability. It influences human health indirectly through extreme temperature and moisture conditions that may accelerate the spread of some vector-borne viral diseases, like dengue fever (DF). This work examines the spatial distribution of association between ENSO and DF in the countries of the Americas during 1995-2004, which includes the 1997-1998 El Niño, one of the most important climatic events of 20(th) century. Data regarding the South Oscillation index (SOI), indicating El Niño-La Niña activity, were obtained from Australian Bureau of Meteorology. The annual DF incidence (AIy) by country was computed using Pan-American Health Association data. SOI and AIy values were standardised as deviations from the mean and plotted in bars-line graphics. The regression coefficient values between SOI and AIy (rSOI,AI) were calculated and spatially interpolated by an inverse distance weighted algorithm. The results indicate that among the five years registering high number of cases (1998, 2002, 2001, 2003 and 1997), four had El Niño activity. In the southern hemisphere, the annual spatial weighted mean centre of epidemics moved southward, from 6° 31' S in 1995 to 21° 12' S in 1999 and the rSOI,AI values were negative in Cuba, Belize, Guyana and Costa Rica, indicating a synchrony between higher DF incidence rates and a higher El Niño activity. The rSOI,AI map allows visualisation of a graded surface with higher values of ENSO-DF associations for Mexico, Central America, northern Caribbean islands and the extreme north-northwest of South America.

Triatominae Survey (hemiptera: Heteroptera: Reduviidae) In The South-central Region Of The State Of Bahia, Brazil Between 2008 And 2013.

Triatomine surveillance in rural areas, artificial ecotypes, and natural ecotopes of the cities of Caturama, Ibipitanga, Macaúbas, and Seabra in the south-central region of the Brazilian state of Bahia was carried out between 2008 and 2013. Natural infection by Trypanosoma cruzi was evaluated in the specimens collected to monitor vectors of Chagas disease. A total of 1,357 specimens were collected, and four species were identified: Triatoma sordida (83%), Triatoma lenti (16.4%), Triatoma pseudomaculata (0.5%), and Panstrongylus geniculatus (0.1%). Triatoma sordida was found in four cities, only 0.7% in intradomiciliary environments. Triatoma lenti was found only in Macaúbas; 8.5% were found in intradomiciliary environments, 88.3% in peridomiciliary environments, and 3.1% in sylvatic environments. Natural infection by T. cruzi was 0.5% for T. sordida and 3.1% T. lenti. All of these cases were found in peridomiciliary environments of Macaúbas. As the results show, triatomines were found in intradomiciliary environments in three cities that were surveyed in the south-central region of the state of Bahia. Thus, an epidemiologic survey should be performed to avoid the risk of transmission to the population.
