CFH Y402H polymorphism and response to intravitreal Ranibizumab in brazilian patients with neovascular age-related macular degeneration

Objective: To investigate the association between CFH gene polymorphism and response to ranibizumab in Brazilian patients with neovascular age-related macular degeneration (AMD).Methods: 95 patients were genotyped for the CFH rs1061170 (Y402H) single nucleotide polymorphism. Patients with neovascular AMD initially received intravitreal ranibizumab injections for three months and were retreated as needed. Visual acuity (VA) and central retinal thickness (CRT) were measured before treatment and at 1, 3, 6, and 12 months post-treatment.Results: For patients with the TT and TC genotypes, paired comparisons of VA showed a statistically significant improvement when the data obtained at all visits were compared with baseline. Patients homozygous for the risk genotype (CC) did not show a statistically significant improvement when VA obtained at visits 1, 3, 6 and 12 were compared with baseline. For all genotypes, paired comparisons of CRT showed a statistically significant improvement when the data obtained at visits 1, 3, 6 and 12 were compared with baseline.Conclusion: Patients with the CC genotype showed poorer long-term functional response to intravitreal ranibizumab.

Reproductive outcome in pregnant women with recurrent pregnancy loss

Abstract PURPOSE: To estimate the future pregnancy success rate in women with a history of recurrent pregnancy loss. METHODS: A retrospective cohort study including 103 women seen at a clinic for recurrent pregnancy loss (loss group) between January 2006 and December 2010 and a control group including 204 pregnant women seen at a low-risk prenatal care unit between May 2007 and April 2008. Both groups were seen in the university teaching hospital the Maternidade Climério de Oliveira, Salvador, Bahia, Brazil. Reproductive success rate was defined as an alive-birth, independent of gestational age at birth and survival after the neonatal period. Continuous variables Means and standard deviations (SD) were compared using Student's t-test and nominal variables proportions by Pearson χ2test. RESULTS: Out of 90 who conceived, 83 (91.2%) had reproductive success rate. There were more full-term pregnancies in the control than in the loss group (174/187; 92.1 versus 51/90; 56.7%; p<0.01). The prenatal visits number was satisfactory for 76 (85.4%) women in the loss group and 125 (61.3%) in the control (p<0.01). In this, the beginning of prenatal care was earlier (13.3; 4.2 versus 19.6; 6.9 weeks). During pregnancy, the loss group women increased the weight more than those in the control group (58.1 versus 46.6%; p=0.04). Although cervix cerclage was performed in 32/90 women in the loss group, the pregnancy duration mean was smaller (34.8 weeks; SD=5.6 versus 39.3 weeks; SD=1.6; p<0.01) than in the control group. Due to gestational complications, cesarean delivery predominated in the loss group (55/83; 64.7 versus 73/183; 39.5%; p<0.01). CONCLUSION: A very good reproductive success rate can be attributed to greater availability of healthcare services to receive pregnant women, through prenatal visits (scheduled or not), cervical cerclage performed on time, and available hospital care for the mother and newborn.

Health management practices and disease prevalence in dairy sheep systems in Argentina

A cross-sectional survey of 19 dairy sheep farms in Argentina was carried out with the purpose to know farm management, health practices, and occurrence and mortality of diseases. The survey comprised 40% of all sheep milking farms in Argentina. A questionnaire was conducted by way of personal interviews with sheep owners during farm visits. The proportions of farms reporting routine vaccination for clostridial diseases, contagious ecthyma, pneumonia and mineral and vitamin parenteral administration were 63%, 47.3%, 16.6% and 42.1% respectively. Regular treatment against lice was used in 37.5% of the farms, and 89.5% o the farmers treated against gastrointestinal nematodes (GIN). The mean number of GIN drenches per farm was 2.26±1.78 annually. In 68.4% of the milking flocks the California Mastitis Test was regularly done and 55.6% of the farmer managers had sampled their flocks once a year for Brucella ovis antibodies. During the pre-mating period respectively 68.4% and 50% of farmers clinically examined their rams and ewe for general health and teeth condition. The udders of ewes were frequently inspected at the start of each milking period. The most important parasite problems noticed were GIN (reported by 57.9% of farmers), lice (57.9%) and scabies (10.5%) and the most frequent infectious diseases were ecthyma (73.7%), pneumonia and other respiratory problems (57.9%), clinical mastitis (55.6%), clostridial diseases (36.9%) and foot lameness (35.2%). Photosensitivity (47.4%) and ruminal acidosis (42.1%) were reported as other frequent toxic or metabolic disorders. Owners mentioned that the mean lifespan or milk productive time per ewe was 4.5±1.4 years. Perinatal lamb mortality was 8.5% and the total flock mortality rates, above the first 24 h of life was 6.9%. The high rates of lamb mortality during the pre-weaning (10.3%) and post-weaning (5.9%) periods indicate that this problem, as well as the most prevalent diseases, should be the subject of further studies.

Projektien markkinoinnin ja myynnin kehittäminen rakennusalan pk-yrityksessä Venäjän markkinoilla

Tämä diplomityö keskittyy kehittämään työssä käsiteltävän Venäjällä toimivan rakennusalan urakoitsijan projektien markkinointia ja myyntiä. Työssä paneudutaan projektimarkkinoinnin kautta yrityksen markkinointiin ja myyntiin. Käsittelyn aiheena ovat myös proaktiivinen markkinointi ja Venäjän rakennusmarkkinoiden aiheuttamat erityispiirteet. Tutkimuksesta selvisi, että yrityksellä on erityisesti ollut vaikeuksia saada ison luokan projekteja. Usein tähän on ollut syynä kilpailijoiden parempi taloudellinen kilpailukyky. Muutama projekti on myös keskeytynyt tai peruuntunut. Onnistuneiden tarjouskilpailuiden taustalla taas ovat olleet referenssikäynnit, hyvät suhteet asiakkaaseen ja laadukas suorittaminen. Projektimarkkinoinnin kirjallisuuden ja yrityksessä suoritettujen teemahaastattelujen pohjalta yritykselle kehitettiin ennakoivaa markkinointia painottava kokonaisvaltainen markkinointi- ja myyntiprosessi. Tärkeimpiä kohtia prosessissa ovat proaktiivinen projektien etsintä ja projektin valmistelu. Projekteja etsitään osallistumalla teollisuuden alan konferensseihin sekä ottamalla itse yhteyttä asiakkaaseen ja eri toimijoihin. Potentiaaliset projektit seulotaan suuremmasta joukosta ennalta määrättyjen kriteereiden avulla. Projekteihin pyritään aktiivisesti vaikuttamaan ennen tarjouskilpailua, jolloin myös järjestetään referenssikäyntejä. Neuvotteluissa sovelletaan kilpailutilanteen mukaan joustavaa kustannusperusteista hinnoittelua. Suoritetun urakan jälkeen asiakasyrityksen investointisuunnitelmia tutkitaan ja tarpeen vaatiessa pyritään säilyttämään yhteys nukkuvan suhteen aikana. Tällöin järjestetään asiakkaan kanssa seminaareja sekä epävirallisia ta-pahtumia. Yrityksen markkinointia ja myyntiä hankaloittavat Venäjän rakennusmarkkinoiden erityispiirteet. Epävarmuudesta aiheutuvat riskit pitää huomioida katteessa, mutta usein Venäjän erityisolosuhteet tulee vain hyväksyä, koska niihin on vaikea vaikuttaa.

Individual dietary counselling during and after pregnancy: Impact on diet and body weight

In Finland, maternity and child health clinics play a key role in promoting health in young families. Currently, obesity causes the greatest challenges to clinics. In obese pregnant women, an increased risk for metabolic diseases exist which can affect both the mother and child. The purpose of this thesis was to explore the role of dietary counselling: in Finnish health clinics; in the regulation of dietary intake; and in affecting the body weight of women. The main aim was to test the effect of dietary counselling and probiotic intervention on dietary intake and maternal body weight during and after pregnancy. In addition to dietary counselling, the effect of other factors, such as eating behaviour on dietary intake and body weight control after pregnancy was assessed. Another aim was also to evaluate dietary counselling practices by nurses (n = 327) in Finnish health clinics assessed by a questionnaire. At the beginning of the pregnancy, women (n = 256) enrolled in a dietary intervention study, were randomised into three groups. One group received dietary counselling with probiotics, one had counselling with placebo and the third group was the control group. The control group consisted of women whom did not receive counselling and took placebo. Probiotics and placebo supplements were used until the end of exclusive breastfeeding or six months after pregnancy. Women were followed from early pregnancy up to four years after pregnancy. Follow-up visits took place three times during pregnancy, at one and six months, and one, two and four years after pregnancy. Dietary counselling, provided by a nutritionist, aimed to influence the quality of dietary fat intake. Dietary counselling is important to provide in clinics, as determined by the nurses, and these nurses expressed a want to improve their own nutritional knowledge through education. The nurses had varying knowledge of current dietary recommendations. Dietary counselling for women during and after pregnancy resulted in beneficial changes in dietary intake up to one year after pregnancy and body weight and waist circumference up to four years after pregnancy. Probiotics had a beneficial effect together with dietary counselling on waist circumference until one year after pregnancy, but not throughout the long term, four years after pregnancy. Other factors, such as eating behaviour, associated with dietary intake and body weight control after pregnancy. Specifically, dietary recommendations are reached amongst women whom had high cognitive restraint in their eating behaviour and did not demonstrate uncontrolled eating. Overweight women more frequently emotionally ate compared to normal weight women and women with central adiposity related more frequently to having an uncontrolled eating behaviour than women with normal waist circumference. In addition, being overweight prior to pregnancy and excessive weight gain during pregnancy associated with increased body weight retention after pregnancy. This study showed that individual dietary counselling is useful in influencing dietary intake which adheres to dietary recommendations and this counselling influences, favourably, body weight after pregnancy. Especially, women with the risk for weight retention, such as women who have emotional and uncontrolled eating behaviours, who were overweight prior to pregnancy or those who had excessive weight gain during pregnancy, may benefit from individual dietary counselling. This study underscores the need to develop dietary counselling practices for pregnant women and their follow-up after pregnancy in Finnish health clinics. These practices include increasing the efficacy of the counselling such as collaboration with families, having knowledgable health professionals and having sufficient resources.

Valtatie 1 liikenneturvallisuustarkastus : Tarkastusraportti

Tämän työn tavoitteena oli tarkastella liikenneturvallisuuden kehittymistä moottoritien rakentamisen jälkeen valtatiellä 1 Varsinais-Suomen ja Uudenmaan ELY-keskusten alueilla välillä Turku – Lohja. Laadittu tarkastus perustui onnettomuustietoihin, tierekisteritietoihin sekä maastokäynteihin. Valtatien 1 liikenneturvallisuustaso on lähtökohtaisesti hyvä ja liikenneympäristön turvallisuusriskit ovat pienet. Liikenneturvallisuustilanne on parantunut merkittävästi moottoritieksi rakentamisen jälkeen. Valtatiellä 1 tapahtuneet henkilövahinkoon johtaneet onnettomuudet ovat vähentyneet 60 - 80 % moottoritien rakentamisen jälkeen, mikä tarkoittaa lähes 40 henkilövahinko-onnettomuutta vähemmän vuosittain. Kuolemaan johtaneiden onnettomuuksien vähenemä oli 2-3 onnettomuutta vuosittain. Moottoritiellä tapahtuneista henkilövahinkoon johtaneista onnettomuuksista yleisimpiä ovat yksittäisonnettomuudet ja peräänajo-onnettomuudet. Henkilövahinko-onnettomuuksista noin 60 % johtuu tieltä suistumisista. Onnettomuusrekisteritietojen mukaan henkilövahinkoon johtaneita kohtaamisonnettomuuksia ei tapahtunut vuosina 2007– 2011, vaikka väärään suuntaan ajamisesta johtuvat kuolonkolarit on aikaisemmin todettu vakiintuneeksi onnettomuustyypiksi moottoriteillä. Tehdyn onnettomuusanalyysin sekä maastokäyntien perusteella etenkin vanhempien moottoritieosuuksien liikenneturvallisuuden tilaa voidaan ja tulee kuitenkin edelleen parantaa ja liikenneturvallisuustasoa nostaa. Yksittäisonnettomuuksia voidaan estää ja niiden seurauksia merkittävästi lieventää reunaympäristöä kehittämällä. On kuitenkin huomattava, että kaikkia onnettomuuksia ei voida estää tieteknisin keinoin ja liikennejärjestelmää kehittämällä. Maastokäynneillä silmämääräisesti todettuihin puutteisiin pohdittiin parantamistoimenpiteitä Varsinais-Suomen ELY-keskuksen alueelle. Toimenpiteissä erityishuomiota on kiinnitetty tieympäristön törmäysturvallisuuteen ja väärään suuntaan ajamisen riskin estämiseen ramppiliittymissä. Tieympäristön törmäysturvallisuutta on esitetty parannettavaksi pääasiassa puuston raivauksella ja kaiteiden lisäämisellä. Kaiteiden lisäämisen sijasta on mahdollista parantaa törmäysturvallisuutta maatäytöllä niissä kohdissa, jossa ulkoluiska on liian matala kallioleikkauksen kohdalla. Ramppiliittymissä väärään suuntaan ajamisen riskiä pyritään taas estämään mm. lisäämällä kielletyn ajosuunnan liikennemerkkejä.

Porin seudun liikenneturvallisuussuunnitelma

Porin seudulle laadittiin liikenneturvallisuussuunnitelma Harjavallan, Huittisen, Kokemäen, Luvian, Merikarvian, Nakkilan, Pomarkun, Porin ja Ulvilan kuntien alueelle. Suunnitelmat laadittiin kuntien ja Varsinais-Suomen ELY-keskuksen yhteistyönä. Suunnitelma sisältää turvallisuuden parantamisen lisäksi kestävien liikkumismuotojen edistämistä. Seudun liikenneturvallisuuden ja liikkumisen ongelmia kartoitettiin kaikille kuntalaisille suunnatuilla kyselyillä, onnettomuusanalyysillä sekä maastokäynneillä. Onnettomuusanalyysin perusteella seudun liikenneturvallisuuden tila Porin seudulla on koko maan keskiarvoa heikompi. Vuosittain kuolee noin 10 henkilöä ja loukkaantuu noin 220 henkilöä. Seudulla tapahtuneista onnettomuuksista aiheutuu kustannuksia vuosittain keskimäärin noin 90 miljoonaa euroa, josta kuntien osuus on vuosittain noin 16 miljoonaa euroa. Kyselyn vastauksista ilmeni, että vastaajia huolestutti muun muassa jalankulku- ja pyöräväylien kunto ja esteettömyys sekä talvikunnossapidon taso. Autoilun olosuhteissa tyytymättömyyttä aiheutti teiden kunto ja kunnossapidon taso sekä kouluympäristöjen liikennejärjestelyt. Kyselyyn vastanneista 64 %:lla työ- tai koulumatkan pituus on korkeintaan 5 kilometriä, joten kävelyn ja pyöräilyn edistämisellä seudulla on hyvät edellytykset. Ongelma-analyysin sekä valtakunnallisten tavoitteiden pohjalta seudulle määritettiin liikenneturvallisuustavoitteet. Pitkän aikavälin liikenneturvallisuusvisioksi seudulle asetettiin, että kenenkään ei tarvitse kuolla tai loukkaantua vakavasti liikenteessä ja liikkuminen on vastuullista ja se koetaan turvalliseksi. Määrällisenä tavoitteena on, että nykyisestä 10 keskimäärin vuodessa kuolleesta seudulla kuolisi liikenteessä enintään 6 henkilöä (40 henkilöä / miljoona asukasta) vuonna 2014 ja enintään 3 henkilöä (24 henkilöä / miljoona asukasta) vuonna 2020. Loukkaantuneiden määrän tavoitteena on, että nykyisestä 218 henkilöstä vähennystä olisi 25 % (korkeintaan 163 henkilöä) vuoteen 2020 mennessä. Nuorten onnettomuusriskiä halutaan pienentää 25 % vuoteen 2020 mennessä siten, että heidän riskinsä lähenee muun väestön onnettomuusriskin tasoa. Liikenneympäristön parantamisehdotukset tehtiin noin 300 kohteeseen seudulla. Toimenpiteiden toteuttaminen vaiheistettiin kolmeen ohjeelliseen kiireellisyysluokkaan. Suunnitelmatyön aikana kuntien liikenneturvallisuustyötä aktivoitiin ja perustettiin uudet ryhmät niihin kuntiin, joista ryhmät puuttuivat. Hallintokuntatilaisuuksissa ideoitiin ja käsiteltiin eri liikkujaryhmille sopivia toimintamuotoja liikenneturvallisuuden ja kestävän liikkumisen edistämiseksi. Lisäksi muodostettiin seudullinen liikenneturvallisuusryhmä, joka seuraa ja koordinoi liikenneturvallisuustyötä tulevaisuudessa.

Outcome of human papillomavirus infection among men in the Finnish Family HPV Study

Ihmisen papilloomaviruksen taudinkuva suomalaisperheiden seurantatutkimuksen mieskohortissa Tieto ihmisen papilloomaviruksen (HPV) yhteydestä eri anatomisten alueiden sairauksien syntyyn on lisännyt mielenkiintoa miehen papilloomavirustulehduksen taudinkulun selvittämiseksi. Tämä väitöskirjatyö on osa suomalaista seurantatutkimusta, jossa tutkitaan HPVinfektioiden tartuntareittejä 329 perheessä. Väitöstyössä keskitytään tutkimukseen osallistuneiden 131 miehen aineistoon. Suun limakalvonäytteet otettiin seitsemässä aikapisteessä. Lisäksi otettiin sukuelinalueen näytteet kahdella seurantakäynnillä. Riskitekijöitä kartoittava kyselytutkimus teetettiin tutkimuksen alkutilanteessa sekä viimeisellä seurantakäynnillä. Oireettomat HPV infektiot olivat alkutilanteessa yleisiä molemmilla sukupuolilla (miesten suu 18,3 % ja sukuelinalue 35,9 %, naisten suu 17,2 % ja kohdunsuu 18,8 %), mutta HPV:n genotyyppien vastaavuus partnerien välillä oli vähäinen. Naisen, mutta ei miehen, seksuaalinen riskikäyttäytyminen oli yhteydessä pariskunnan HPV tyyppien vastaavuuteen. Partnerin ja siviilisäädyn vaihtaminen lisäsivät miehen riskiä saada uusia HPV infektioita. Miehen suun limakalvonäytteistä löytyi kaikkiaan 17 eri HPV tyyppiä. Suun HPV-tulehduksen esiintyvyys vaihteli eri aikapisteissä 15 %:sta 31 %:iin. Uusien HPV tulehdusten ilmaantumisaika vaihteli 3,9 ja 25,7 kuukauden välillä. Suun HPV infektio parani valtaosalla miehistä. Suun krooninen HPV-infektio todettiin 14 %:lla miehistä. Näiden infektioiden keskimääräinen kesto vaihteli 6.0:sta 30.7:ään kuukauteen. Tupakointi lisäsi korkean riskin HPV tyyppien aiheuttamien suun kroonisten infektioiden riskiä, kun taas aikaisemmin sairastetut sukuelinten kondyloomat suojasivat siltä. Tuloksemme osoittavat, että miehen oireeton HPV tulehdus on yleinen suussa ja sukuelinten alueella. Vakaa parisuhde suojaa uusilta HPV tulehduksilta. Tupakoinnilla on keskeinen merkitys suun HPV-infektion kroonistumisessa.

Phenology, fruit set and dispersal of Cordia multispicata Cham., an important weed shrub of abandoned pastures in eastern Amazonia

ABSTRACT - (Phenology, fruit set and dispersal of Cordia multispicata Cham., an important weed shrub of abandoned pastures in eastern Amazonia). The reproductive ecology of the distylous tropical shrub Cordia multispicata was studied in an abandoned pasture in Paragominas County , Pará state, Brazil. It is a common species in the Amazon basin where it occurs as a weed in open and disturbed habitats. C. multispicata has many flowers per inflorescence (85 ± 12) but 84% abort before fertilization. Flowering occurs throughout the year. Fruits are small, with a red fleshy pericarp (skin-pulp) attractive to birds. Fruit set is lower during the dry season (less than 30%) and higher during the rainy season when there are many visits of insects to the flowers. Fruiting has a peak between the end of the dry season and the middle of the rainy season. Nineteen bird species were observed foraging for the fruits of C. multispicata, and 79% of those species can be considered as potential dispersal agents. The efficient seed dispersal and aggregated spatial distribution associated with some characteristics of the dispersors greatly contributed to the success of this species in abandoned pastures of eastern Amazonia.

Reproductive biology of Pseudolaelia corcovadensis Porto & Brade (Orchidaceae): melittophyly and self-compatibility in a basal Laeliinae

The floral biology, mating systems and phenology of Pseudolaelia corcovadensis (Orchidaceae), in the "Estação de Pesquisa e Desenvolvimento Ambiental de Peti", São Gonçalo do Rio Abaixo, Minas Gerais state was studied. This species flowers from April to September, with a higher availability of flowers in June and July. The flowers are dark-pink, strongly zygomorphic, and have osmophores and nectar-guides absorbing ultraviolet light. However, the flowers of P. corcovadensis do not present nectar and are pollinated by Bombus (Fervidobombus) atratus Franklin, 1913 (Hymenoptera: Apidae) by deceit. Apparently, the flowers do not form a model-mimic pair with other species in the community, but mimic a generalized melittophilous food-flower. As a consequence, visits are very rare and fruit set is low (18%). Pseudolaelia corcovadensis is self-compatible and presents inbreeding depression in the early stages of development. The phylogenetic position of the genus Pseudolaelia and studies on floral biology in related genera suggest that melittophyly and self-compatibility are basal characters in the subtribe Laeliinae, with subsequent adaptive radiation to pollination by hummingbirds, Lepidoptera, Diptera and other Hymenoptera.

Negotiating home and belonging. Young Kurds in Finland

This study looks at negotiation of belonging and understandings of home among a generation of young Kurdish adults who were born in Iraq, Iran, and Turkey and who reached adulthood in Finland. The young Kurds taking part in the study belong to the generation of migrants who moved to Finland in their childhood and early teenage years from the region of Kurdistan and elsewhere in the Middle East, then grew to adulthood in Finland. In theoretical terms, the study draws broadly from three approaches: transnationalism, intersectionality, and narrativity. Transnationalism refers to individuals’ cross-border ties and interaction extending beyond nationstates’ borders. Young people of migrant background, it has been suggested, are raised in a transnational space that entails cross-border contacts, ties, and visits to the societies of departure. How identities and feelings of belonging become formed in relation to the transnational space is approached with an intersectional frame, for examination of individuals’ positionings in terms of their intersecting attributes of gender, age/generation, and ethnicity, among others. Focus on the narrative approach allows untangling how individuals make sense of their place in the social world and how they narrate their belonging in terms of various mechanisms of inclusion and exclusion, including institutional arrangements and discursive categorisation schemes. The empirical data for this qualitative study come from 25 semi-structured thematic interviews that were conducted with 23 young Kurdish adults living in Turku and Helsinki between 2009 and 2011. The interviewees were aged between 19 and 28 years at the time of interviewing. Interview themes involved topics such as school and working life, family relations and language-learning, political activism and citizenship, transnational ties and attachments, belonging and identification, and plans for the future and aspirations. Furthermore, data were collected from observations during political demonstrations and meetings, along with cultural get-togethers. The data were analysed via thematic analysis. The findings from the study suggest that young Kurds express a strong sense of ‘Kurdishness’ that is based partially on knowing the Kurdish language and is informed by a sense of cultural continuity in the diaspora setting. Collective Kurdish identity narratives, particularly related to the consciousness of being a marginalised ‘other’ in the context of the Middle East, are resonant in young interviewees’ narrations of ‘Kurdishness’. Thus, a sense of ‘Kurdishness’ is drawn from lived experiences indexed to a particular politico-historical context of the Kurdish diaspora movements but also from the current situation of Kurdish minorities in the Middle East. On the other hand, young Kurds construct a sense of belonging in terms of the discursive constructions of ‘Finnishness’ and ‘otherness’ in the Finnish context. The racialised boundaries of ‘Finnishness’ are echoed in young Kurds’ narrations and position them as the ‘other’ – namely, the ‘immigrant’, ‘refugee’, or ‘foreigner’ – on the basis of embodied signifiers (specifically, their darker complexions). This study also indicates that young Kurds navigate between gendered expectations and norms at home and outside the home environment. They negotiate their positionings through linguistic repertoires – for instance, through mastery of the Finnish language – and by adjusting their behaviour in light of the context. This suggests that young Kurds adopt various forms of agency to display and enact their belonging in a transnational diaspora space. Young Kurds’ narrations display both territorially-bounded and non-territorially-bounded elements with regard to the relationship between identity and locality. ‘Home’ is located in Finland, and the future and aspirations are planned in relation to it. In contrast, the region of Kurdistan is viewed as ‘homeland’ and as the place of origins and roots, where temporary stays and visits are a possibility. The emotional attachments are forged in relation to the country (Finland) and not so much relative to ‘Finnishness’, which the interviewees considered an exclusionary identity category. Furthermore, identification with one’s immediate place of residence (city) or, in some cases, with a religious identity as ‘Muslim’ provides a more flexible venue for identification than does identifying oneself with the (Finnish) nation.

Nectar and pollen production in pumpkin (Cucurbita pepo L.)

Cucurbitaceae species depend on pollination by honey bees for fruit production. The overall objective of this work was to evaluate the potential of C. pepo for pollen and nectar production, that could help maintain colonies placed in the field. Plants of pumpkin were cultivated in field, in 1996 and 1997. Before anthesis, male flowers were covered to prevent visits by bees and other insects. After anthesis the flowers were uncovered and the following parameters were evaluated: 1) nectar production; 2) total sugar concentration in the nectar; 3) nectar replacement; and 4) production of pollen and flowers during the crop cycle. Nectar production varied from 18 to 79 µL flower-1 and increased progressively from 7h to 13h. The sugar concentration, measured at 7h, 9h and 11h, did not vary, averaging 50.5% ± 0.5% in 1996 and 40.5% ± 0.6% in 1997. At 13h the concentration decreased to 42% in 1996 and to 35% in 1997. Total daily nectar production was not influenced by removing nectar several times per day, indicating that nectar secretion is not stimulated or inhibited by frequent removal. The number of pollen grains did not differ in the two years, with an average of 43,669 ± 1,382 grains per flower. The peak rate of male and female flowers occurred from 60 to 66 days after planting (DAP) with 34.6 male flowers and 2.2 female flowers per plant, respectively. Cucurbita pepo has a potential for honey and pollen production of about 105 and 160 kg per hectare per season, respectively, which is enough to sustain, at least, five honeybee colonies.

International Advanced Water Technologies Centre, IAWTC/LADEC and LUT 2013 : Questionnaire Responses from Russian Drinking Water and Wastewater Treatment Plants

In this report, information is published concerning Russian water and wastewater treatment plants. The information is based on a questionnaire sent to 70 water and wastewater treatment plants in 2012-2013. The questionnaire was prepared by the International Advanced Water Technologies Centre (IAWTC) and Lahti Development Company (LADEC). The questions dealt with an assessment of the present state, the need for changes, renovation, investments, and how to improve the efficiency of the operation by training and investments. A significant need to renew the old pipelines, constructions, and processes was clearly evident. The aggregated answers can be utilized in Russia as internal benchmarking in order to arrange training and plant visits, which were requested in many of the answers. Sharing this open report with the respondents can aid networking and awareness of HELCOM requirements which relate to waste water treatment plants discharging their waste water directly or indirectly into the Baltic Sea. The aim of this report is to provide information for Finnish small and medium size companies (SMEs) as regards possible water related exportation to different parts of Russia.

Frugivory on Margaritaria nobilis L.f. (Euphorbiaceae): poor investment and mimetism

Dehiscent fruits of Euphorbiaceae usually have two stages of seed dispersal, autochory followed by myrmecochory. Two stages of Margaritaria nobilis seed dispersal were described, the first stage autochoric followed by ornithocoric. Their dehiscent fruits are green and after they detached from the tree crown and fall on the ground, they open and expose blue metallic cocas. We studied the seed dispersal system of Margaritaria nobilis in a semi-deciduous forest in Brazil. In 80 h of focal observations, we recorded only 12 visits of frugivores, however the thrush Turdus leucomelas was the only frugivore that swallowed the fruits on the tree crown. Pitylus fuliginosus (Fringilidae) and Pionus maximiliani (Psittacidae) were mainly pulp eaters, dropping the seeds below the tree. On the forest floor, after fruits dehiscence, jays (Cyanocorax chrysops), guans (Penelope superciliaris), doves (Geotrygon montana) and collared-peccaries (Pecari tajacu) were observed eating the blue diaspores of M. nobilis. Experiments in captivity showed that scaly-headed parrots (Pionus maximiliani), toco toucans (Ramphastos toco), jays (Cyanochorax chrysops), and guans (Penelope superciliaris) consumed the fruits and did not prey on the seeds before consumption. The seeds collected from the feces did not germinate in spite of the high viability. The two stages of seed dispersal in M. nobilis resembles the dispersal strategies of some mimetic species. However M. nobilis seeds are associated with an endocarp, it showed low investment in nutrients, and consistent with this hypothesis, M. nobilis shared important characteristics with mimetic fruits, such as bright color display, long seed dormancy and protection by secondary compounds.

Pollination biology in Jacaranda copaia (Aubl.) D. Don. (Bignoniaceae) at the "Floresta Nacional do Tapajós", Central Amazon, Brazil

Jacaranda copaia (Aubl.) D. Don is a pioneer tree widespread in the Brazilian Amazon, usually found colonizing forest gaps and altered areas, and the forest fragment edges. This study investigated aspects of the floral biology, breeding system and pollinators of J. copaia trees. Flowering lasts from August to November, during the low rainfall period extending up to four weeks per tree and 3-4 months for the population as a whole, characterizing a cornucopia flowering pattern. The fruit set ends in the beginning of the rainy season, with wind dispersed winged seeds. Fruit set from open pollination was 1.06% (n = 6,932). Hand pollination using self-pollen (n = 2,099) did not set fruits. Cross-pollination resulted in 6.54% fruit set (n = 2,524), representing six times more than the natural pollination rate (1.06%, n = 6,932). Flowers excluded from insect visitation (automatic self-pollination) did not set fruits (n = 5,372). Pollen tube growth down to ovary was detected under fluorescence microcoscopy in cross-pollinated and selfed pistils. The species is an obligate allogamous plant, with late-acting self-incompatibility system. Approximately 40 species of native bees visited the flowers, but the main pollinators were medium-sized solitary bees as Euglossa and Centris species due to the compatibility between their body sizes with the corolla tube, direct contact with the reproductive structures and high frequency of visits.
