Water requirement and yield of fig trees under different drip irrigation management

This work aimed to study the effect of drip irrigation management on growth and yield of the 'Roxo de Valinhos' fig tree (Ficus carica L.), at three years old, and to determine crop coefficients (Kc) and its water requirement (ETc) under Baixada Fluminense climate and soil conditions, state of Rio de Janeiro, Brazil. The study was carried out in the experimental area of SIPA (Sistema Integrado de Produção Agroecológica) in Seropédica, Rio de Janeiro State, from July 2011 to May 2012. The experimental area was divided in two blocks, named B1 (sandy clay loam texture) and B2 (loamy sand texture). In each block, irrigation frequencies (IF) of two (T1) and four days (T2) were evaluated, as well as the irrigation absence (T3). Irrigation management and water consumption determination were performed through the soil water balance, using the TDR technique. Plant growth was not affected by IF, differing only in the number of produced internodes. For both soil textures, the mean Kc was 0.60, with a significant difference (p<0.05) only for IF. The estimated mean yield showed no significant differences between both textural classes, ranging from 6,612 kg ha-1 (T3) to 8,554 kg ha-1 (T1). This study indicates the importance of irrigation frequency in the irrigation management of fig trees cultivated in soils with different physical characteristics.

Effectiveness of the KiVa Antibullying Program

According to the participant role approach (Salmivalli, Lagerspetz, Björkqvist, Österman, & Kaukiainen, 1996), bullying is a group phenomenon that is largely enabled and maintained by the classmates taking on different participant roles (e.g., reinforcers or assistants of the bully). There is, however, very little evidence on whether the bystander behaviors actually have an effect on the risk for victimization. Furthermore, the participant role approach implies that the bystanders should be used in putting an end to bullying. This view has been put into practice in the KiVa antibullying program, but it has not yet been investigated whether the program is effective. Four studies were conducted to investigate, (a) whether the behaviors of bystanders have an effect on the risk for victimization (Study I) and (b) whether the KiVa program reduces bullying and victimization and has other beneficial effects as well (Studies II–IV). The participants included large samples of elementary and lower secondary school students (Grades 1–9) from Finland. The assessments were done with web-based questionnaires including questions about bullying and victimization (both self- and peer reports), and about several bullying-related constructs. The results of this thesis suggest that bystander behaviors in bullying situations may influence the risk for victimization of vulnerable students. Moreover, the results indicate that the KiVa antibullying program is effective in reducing victimization and bullying. The program effects are larger in elementary schools than in lower secondary schools, whereas in Grades 8 and 9, they are larger for boys than girls for some peer-reported outcomes. The magnitude of the overall effects can be considered practically significant when obtained in a large-scale dissemination of the program.

Use of alcohol before and after bariatric surgery

OBJECTIVE: to assess alcohol intake in the bariatric surgery pre and postoperative periods. METHODS: Patients were interviewed atSurgery Clinic of the Hospital das Clínicas da Universidade Federal de Pernambuco - HC/UFPE (Brazil) from July 2011 to March 2012. We analyzed socioeconomic, anthropometric and clinical variables. We used the Alcohol Use Disorders Identification Test (AUDIT C). RESULTS: One hundred nineteen patients were enrolled (mean age: 41.23+11.30 years), with a predominance of the female gender (83.2%), non-Caucasian race (55%), married individuals or in a stable union (65.5%), with a high school education (40.3%)and active in the job market (37%). Weight and body mass index (BMI) were 128.77+25.28Kg and 49.09+9.26Kg/m2,respectively in the preoperative period (class II obesity) and 87.19+19.16Kg and 33.04+6.21Kg/m2, respectively in the postoperative period (class I obesity) (p<0.001). Hypertension was the most frequent disease in the pre (66.6%) and postoperative (36.5%) periods. The prevalence of alcohol use was 26.6% in the preoperative period, of which 2.2% of high risk, and 35.1% in the postoperative period, of which 1.4% of probable dependence; this difference did not achieve statistical significance (p=0.337). CONCLUSION: The prevalence of abusive alcohol intake and/or probable dependence was low in both the pre and postoperative periods, with little evidence of risky consumption among the patients submitted to bariatric surgery.

Night admission is an independent risk factor for mortality in trauma patients - a systemic error approach

ABSTRACTObjective:to assess the impact of the shift inlet trauma patients, who underwent surgery, in-hospital mortality.Methods:a retrospective observational cohort study from November 2011 to March 2012, with data collected through electronic medical records. The following variables were statistically analyzed: age, gender, city of origin, marital status, admission to the risk classification (based on the Manchester Protocol), degree of contamination, time / admission round, admission day and hospital outcome.Results:during the study period, 563 patients injured victims underwent surgery, with a mean age of 35.5 years (± 20.7), 422 (75%) were male, with 276 (49.9%) received in the night shift and 205 (36.4%) on weekends. Patients admitted at night and on weekends had higher mortality [19 (6.9%) vs. 6 (2.2%), p=0.014, and 11 (5.4%) vs. 14 (3.9%), p=0.014, respectively]. In the multivariate analysis, independent predictors of mortality were the night admission (OR 3.15), the red risk classification (OR 4.87), and age (OR 1.17).Conclusion:the admission of night shift and weekend patients was associated with more severe and presented higher mortality rate. Admission to the night shift was an independent factor of surgical mortality in trauma patients, along with the red risk classification and age.

Vascular trauma in the Amazon - the challenge of great distances

ABSTRACTObjective:to evaluate the incidence of unfavorable outcomes in vascular trauma patients and their possible correlation to the distance between the city where the injury was sustained and the hospital where the patient received definitive treatment.Methods:descriptive and retrospective study. Data were collected from medical records of patients submitted to surgical procedures for arterial or venous injuries from February 2011 to February 2013 at the only trauma center providing vascular surgery in a vast area of the Amazon region. Trauma date, patient gender and age, mechanism and anatomic topography of injury, surgical management, need for surgical re-intervention, hospitalization period, postoperative complications, mortality and limb amputation rates were analyzed. The incidence of unfavorable outcomes was assessed according to the distance between the city where the vascular injury was sustained and the trauma center.Results: One hundred seventy-three patients with 255 vascular injuries were analyzed; 95.95% were male (p<0.05), mean age of 28.92 years; 47.4% were caused by firearm projectiles (p<0.05); topographic distribution: 45.66% lower limbs (p<0.05), 37.57% upper limbs, 6.94% abdominal, 5.2% thoracic and 4.62% were cervical vascular injuries; 51.42% of patients required hospitalization for seven days or less (p<0.05); limb amputation was necessary in 15.6% and the overall mortality was 6.36%.Conclusion:distances greater than 200Km were associated to longer hospitalization period; distances greater than 300Km were associated to increased limb amputation probability; severe vascular trauma have an increased death probability when patients need to travel more than 200Km for surgical treatment.

Epidemiological evaluation of hepatic trauma victims undergoing surgery

Objective : to evaluate the epidemiological variables and diagnostic and therapeutic modalities related to hepatic trauma patients undergoing laparotomy in a public referral hospital in the metropolitan region of Vitória-ES. Methods : we conducted a retrospective study, reviewing charts of trauma patients with liver injuries, whether isolated or in association with other organs, who underwent exploratory laparotomy, from January 2011 to December 2013. Results : We studied 392 patients, 107 of these with liver injury. The male: female ratio was 6.6 : 1 and the mean age was 30.12 years. Penetrating liver trauma occurred in 78.5% of patients, mostly with firearms. Associated injuries occurred in 86% of cases and intra-abdominal injuries were more common in penetrating trauma (p <0.01). The most commonly used operative technique was hepatorrhaphy and damage control surgery was applied in 6.5% of patients. The average amounts of blood products used were 6.07 units of packed red blood cells and 3.01 units of fresh frozen plasma. The incidence of postoperative complications was 29.9%, the most frequent being infectious, including pneumonia, peritonitis and intra-abdominal abscess. The survival rate of patients suffering from blunt trauma was 60%, and penetrating trauma, 87.5% (p <0.05). Conclusion : despite technological advances in diagnosis and treatment, mortality rates in liver trauma remain high, especially in patients suffering from blunt trauma in relation to penetrating one.

Success Factors of Accelerators

There is wide interest in new business creation especially in high-growth companies because of the transition from the industrial era to the information era. Previously traditional industry has been a major employer but now industrial employment is moving to countries that provide cheaper labor, and therefore Western countries are reaching for new solutions that could safeguard the current stage of economic wealth. High-growth companies are seen as one opportunity. The aim of this study is to clarify the success factors of accelerators. Acceleration is a relatively new phenomenon, which has its roots in the venture capital industry. Their fundamental goal is to create high-growth companies that have global market potential. Accelerators could be defined as venture-to-capital actors that bridge the competence and equity gaps of startups. The access to the knowledge and funding are the prerequisites of the existence of accelerator. This research was qualitative and based on 18 semi-structured or thematic interviews with 15 accelerators and topic related professionals from Finland, Estonia, Denmark, Germany, the UK and the US. The data was analyzed with a content analysis approach. The study revealed three fundamental preconditions for success. First, the deep business knowledge and access to relevant networks is a foundation and fundamental precondition. Second, the ability to transfer knowledge from the accelerator to startups has significant importance. And third, the dynamics of an accelerator organization can restrict the use of business knowledge. Moreover, the attraction of an accelerator and team selection are crucial issues for success.

Mädätysjäännöksen rakeistus, terminen kuivaus ja energiahyötykäyttö

Tutkimuksen tavoitteena oli kartoittaa alueellisen jäteyhtiön Kymenlaakson Jäte Oy:n mahdollisuuksia rakeistaa ja termisesti kuivata mekaanisesti kuivattua mädätysjäännöstä sekä mahdollisuuksia toimittaa termisesti kuivattua materiaalia energiahyötykäyttöön. Tutkimuksessa selvitettiin myös kokemuksia lattialämmityksen käyttämisestä mädätysjäännöksen kuivaukseen. Tutkimuksessa perehdyttiin erilaisiin rakeistus- ja kuivausmenetelmiin sekä termisen kuivurin valintaan vaikuttaviin asioihin. Kuvaukset perustuvat kirjallisuudesta ja internetistä saatuihin tietoihin. Tekniikkakuvausten pohjalta lähdettiin kyselemään tarjouksia termisiä kuivauslaitteistoja myyviltä yrityksiltä. Tarjoukset pyydettiin kuiva-ainepitoisuuden muutokselle 30 %:sta 90 %:iin ja oletettiin, että kuivaukseen on käytettävissä lämpöä viideltä kaatopaikkakaasua käyttävältä mikroturbiinilta. Tutkimuksen aikana saatiin tarjous kuudelta yritykseltä. Saadut tarjoukset esiteltiin tiivistetysti raportissa ja kokonaisuudessaan ne sisällytettiin Kymenlaakson Jäte Oy:n laajempaan raporttiin, joka ei ole julkinen. Yritykset antoivat hyvin erilaisia tietoja siitä, mitä tarjoukseen sisältyy, joten tarjoukset eivät olleet suoraan vertailukelpoisia. Tarjouksista myös havaittiin, että jos Mäkikylän biokaasulaitokselta vastaanotettaisiin enimmäismäärä (19 500 t/a) mädätysjäännöstä, mikroturbiineilta saatava lämpömäärä ei riittäisi kuivaamaan kaikkea mädätysjäännöstä 90 % kuiva-ainepitoisuuteen. Tutkimuksen aikana huomattiin myös, että sitovan tarjouksen saamiseksi mädätysjäännös tulee toimittaa testattavaksi, jolloin saadaan vahvistus kuivausmenetelmän soveltuvuudesta kyseiselle materiaalille. Tutkimuksessa selvitettiin myös, minkälaisia kokemuksia löytyy lattialämmityksen käyttämisestä kuivaukseen niin Suomesta kuin maailmalta ja voiko menetelmää käyttää mädätysjäännöksen kuivaukseen. Kyseistä menetelmää on käytetty tehostamaan aurinkokuivausta, joten tutkimuksen aikana perehdyttiin erityisesti aurinkokuivaukseen liittyviin tieteellisiin artikkeleihin. Lattialämmityksen käytöstä löytyi niin heikkouksia kuin vahvuuksia. Suomessa aurinkokuivauksen ja lattialämmityksen yhdistelmä ei ole kuitenkaan päätynyt laajaan käyttöön ja syynä voidaan nähdä muun muassa kylmät ja pimeät vuodenajat sekä suuri pinta-alan tarve. Tutkimusraportissa selvitettiin lisäksi polttolaitosten edustajien kiinnostusta ja rajoituksia ottaa vastaan termisesti kuivattua mädätysjäännöstä. Tutkimuksen aikana otettiin yhteyttä alle 100 km etäisyydellä Kymenlaakson Jäte Oy:stä sijaitsevien jätteenpolttoluvan omaavien yritysten edustajiin. Saatuja vastauksia käsiteltiin tiivistetysti raportissa ja vastaukset sisällytettiin kokonaisuudessaan Kymenlaakson Jäte Oy:n laajempaan raporttiin, joka ei ole julkinen. Puhelinhaastattelujen pohjalta nähtiin, että yrityksillä on kiinnostusta materiaalia kohtaan, mutta samalla vastauksiin vaikuttavat mädätysjäännöksen analyysitulokset. Poltto-ominaisuuksiin liittyvät analyysit tullaan toteuttamaan vuoden 2012 aikana. Laitoksilla oli myös vaihtelevia rajoituksia materiaalia kohtaan, mutta analyysituloksista riippuen materiaalia voidaan hyödyntää energiana tuhansia tai jopa kymmeniä tuhansia tonneja vuodessa alle 100 km etäisyydellä Kymenlaakson Jäte Oy:stä.

Correlation between placental thickness in the second and third trimester and fetal weight

PURPOSE: To investigate relationship between placental thickness during the second and third trimesters and placental and birth weights. METHODS: From January 2011 to June 2012, a total of 250 singleton pregnant women presented at our antenatal clinic were enrolled in this prospective study. All recruited women were assessed at the 1st trimester screening for baseline demographic and obstetric data. The placental thickness was measured trans-abdominally by placing the ultrasound transducer perpendicularly to the plane of the placenta, in the area of the cord insertion at second and third trimester. Pearson's correlation analysis was used to establish the degree of relationship between placental thickness and birth and placental weights. RESULTS: Of 250 recruited participants, 205 women were able to complete the study. The mean age of cases was 26.4±5.1. Values of mean birth and placental weights were 305.56±657.0 and 551.7±104.8 grams respectively. Ultrasonographic measures of placental thickness in second and third trimester and changes between them were 21.68±4.52, 36.26±6.46 and 14.67±5.67 mm respectively. There was a significant positive correlation between placental thickness and birth weight in the second and third trimesters (r=0.15, p=0.03; r=0.14, p=0.04 correspondingly). CONCLUSION: According to our study, birth weight has a positive relation with both second and third trimester placental thickness; however, placental thickness change could not predict low birth weight.

Uterine Doppler velocimetry of the uterine arteries in the second and third trimesters for the prediction of gestational outcome

PURPOSE: The aim of this longitudinal study was to investigate the value of uterine artery Doppler sonography during the second and third trimesters in the prediction of adverse pregnancy outcome in low-risk women. METHODS: From July 2011 to August 2012, a total of 205 singleton pregnant women presenting at our antenatal clinic were enrolled in this prospective study and were assessed for baseline demographic and obstetric data. They underwent ultrasound evaluation at the time of second and third trimesters, both included Doppler assessment of bilateral uterine arteries to determine the values of the pulsatility index (PI) and resistance index (RI) and presence of early diastolic notch. The endpoint of this study was assessing the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of Doppler ultrasonography of the uterine artery, for the prediction of adverse pregnancy outcomes including preeclampsia, stillbirth, placental abruption and preterm labor. RESULTS: The mean age of cases was 26.4±5.11. The uterine artery PI and RI values for both second (PI: 1.1±0.42 versus 1.53±0.59, p=0.002; RI: 0.55±0.09 versus 0.72±0.13, p=0.000 respectively) and third-trimester (PI: 0.77±0.31 versus 1.09±0.46, p=0.000; RI: 0.46±0.10 versus 0.60±0.14, p=0.010 respectively) evaluations were significantly higher in patients with adverse pregnancy outcome than in normal women. Combination of PI and RI >95th percentile and presence of bilateral notch in second trimester get sensitivity and specificity of 36.1 and 97% respectively, while these measures were 57.5 and 98.2% in third trimester. CONCLUSIONS: According to our study, it seems that uterine artery Doppler may be a valuable tool for the prediction of a variety of adverse outcomes in second and third trimesters.

Taxonomy, species richness and biogeography of Finnish crane flies (Diptera, Tipuloidea).

Biodiversity is unequally spread throughout terrestrial ecosystems. The highest species richness of animals and plants is encountered around the Equator, and naturalists observe a decrease in the number of creatures with increasing latitude. Some animal groups, however, display an anomalous species richness pattern, but these are exceptions to the general rule. Crane flies (Diptera, Tipuloidea) are small to large sized, non-biting nematoceran insects, being mainly associated with moist environments. The species richness of crane flies is highest in the tropics, but these insects are species rich and abundant in all biogeographic realms, boreal and arctic biomes included. The phylogeny and systematics of crane flies are still at an early stage and somewhat controversial. New species are constantly discovered even from temperate Europe, faunistically the best known continent. Crane flies have been rather neglected group of insects in Finland. The history of Finnish crane fly taxonomy and faunistics started in 1907, the year when Carl Lundström published his two first articles on tipuloids. Within roughly 100 years there have been only a handful of entomologists studying the Finnish fauna, and the species richness and natural history of these flies have remained poorly understood and mapped. The aim of this thesis is to clarify the taxonomy of Finnish crane flies, present an updated and annotated list of species and seek patterns in regional species richness and assemblage composition. Tipula stackelbergi Alexander has been revised (I). This species was elevated to a species rank from a subspecific rank under T. pruinosa Wiedemann and T. stackelbergi was also deleted from the list of European crane flies. Two new synonyms were found: T. subpruinosa Mannheims is a junior synonym of T. freyana Lackschewitz and T. usuriensis Alexander is a junior synonym of T. pruinosa. A new species Tipula recondita Pilipenko & Salmela has been described (II). Both morphology and COI (mtDNA) sequences were used in the assessment of the status of the species. The new species is highly disjunct, known from Finland and Russian Far East. A list of Finnish crane flies was presented, including the presence of species in the Finnish biogeographical provinces (III). A total of twenty-four species were formally reported for the first time from Finland and twenty-two previously reported species were deleted from the list. A short historical review on the studies of Finnish crane flies has been provided. The current list of Finnish species consists of 338 crane flies (IV, Appendix I). Species richness of all species and saproxylic/fungivorous species is negatively correlated with latitude, but mire-dwelling species show a reversed species richness gradient (i.e. an increase in the number of species toward north). Provincial assemblages displayed a strong latitudinal gradient and faunistic distance increased with increasing geographical distance apart of the provinces. Nearly half (48 %) of the Finnish crane flies are Trans-Palaearctic, roughly one-third (34 %) are West Palaearctic and only 16 and 2 % are Holarctic and Fennoscandian, respectively. Due to the legacy of Pleistocene glaciations, endemic Fennoscandian species are problematic and it is thus concluded that there are probably no true endemic crane flies in this region. Finally, there are probably species living within Finnish borders that have hitherto remained unnoticed. Based on subjective assessment, the number of “true” (i.e. recorded + unknown species) species count of Finnish crane flies is at minimum 350.

Palveluasumisen markkinapotentiaali Suomessa asuvien venäjänkielisten ikäihmisten keskuudessa - Analyysi markkinoista ja kuluttajakäyttäytymisestä

Tutkimus on toimeksianto Yritykseltä X, joka halusi selvitettävän, millaista markkinapotentiaalia on nähtävissä ikäihmisten palveluasumisessa Suomessa asuville venäjänkielisille. Markkinoiden analysoinnin lisäksi tutkimuksessa on selvitetty kohderyhmän kuluttajakäyttäytymistä ja ostokykyä. Tutkimuksen tavoitteena ei ole antaa toimeksiantajalle valmista investointipäätöstä, vaan tuoda tietoa markkinoista ja kohderyhmästä päätöksenteon tueksi. Käytössä on ollut neljä empiiristä aineistoa. Primääriaineistona ovat asiantuntija¬haastattelut sekä kyselyt Yrityksen X venäjänkielisille työntekijöille ja maksaja-asiakkaille – eli kuntien ja sairaanhoitopiirien edustajille. Sekundääriaineistona on joukko suomalaisten Venäjä-asiantuntijoiden viime vuosien tutkimuksia. Pro gradun teoriaosuus on tiivis. Teorian on auttanut kirjoittajaa tarkastelemaan palveluasumisen markkinoita kansainvälisellä vivahteella sekä suomalaisittain uuden kuluttajaryhmän kuluttajakäyttäytymistä ja ostokykyä. Suomessa asuvia venäjänkielisiä ikäihmisiä ei ole aikaisemmassa tutkimuksessa tarkasteltu omana kohderyhmänään, mutta heistä on tehty paljon yhteiskunnallista tutkimusta. Tätä on hyödynnetty muun muassa tarkasteltaessa kohderyhmän kulttuurisia piirteitä, sosiaalisia tapoja, kieltä ja uskontoa. Suomessa asuvista venäjänkielisistä ikäihmistä ei voi puhua yhtenäisenä ryhmänä. Osa yli 65-vuotiaista on suomen kielen taitoisia ja työssään menestyneitä, mutta monen maahanmuuttajan sosiaalinen asema laski heidän muuttaessaan Suomeen. Neuvostoliitossa asuneet ovat tottuneet niukkoihin olosuhteisiin, siihen että samassa taloudessa asui jopa kolme sukupolvea, ja että perhe piti huolta yhteiskunnan tuen ollessa niukkaa. Vaikka venäläisessä kulttuurissa vanhainkodeilla on huono maine, voidaan Suomessa asuvien ikäihmisten keskuudessa nähdä positiivista suhtautumista palveluasumista ja suomalaisia julkispalveluja kohtaan. Mikäli Yritys X rakentaa yksikön Lappeenrantaan, kannattaa potentiaalisina asiakkaina nähdä myös venäläiset terveysmatkailijat ja suunnitella palvelutarjonta laajemmin kuin vain Suomessa asuville venäjänkielisille. Mikäli yksikkö tulee Helsinkiin, on kilpailijana ortodokseille ja venäjänkielisille vanhuksille tarkoitettu Helenan vanhainkoti.
