Parasitism level by helminths and weight gain of calves kept in organic and conventional grazing

Sustainable production is a principle in which we must meet the needs of the present without compromising the capacity of future generations. Despite the successful development of pesticides against endo and ectoparasites found in domestic ruminants, these parasites are still the major problem of the herbivore production system. The purpose of this study was to know the population of gastrintestinal parasites and their influence on weight gain of calves kept in organic and conventional grazing. Thus, organic and conventional calves were randomly selected in 2008 and 2009. The fecal egg count (FEC) indentified the following genders of helminths: Haemonchus, Trichostrongylus, Oesophagostomum, Cooperia, Strongyloides, Trichuris and oocysts of Eimeria. There was no significant difference (p>0.05) between FEC in organic and conventional animals. Calves younger than 6 months showed significant higher infection (p<0.05) than calves between 7 and 12 months of age. The weight gain observed during the study was of 327g/day and 280g/day for conventional and organic systems animals, respectively. Consequently, the combination of sustainable practices of grazing associated with the selective application of anthelmintics may be a feasible alternative for nematode control in a conventional system and in transition to an organic one.

Technological level and epidemiological aspects of sheep husbandry in Minas Gerais, southeastern Brazil

Epidemiological and health aspects of sheep husbandry were assessed on 213 sheep flocks in 142 municipalities from the state of Minas Gerais, southeastern Brazil. An updated questionnaire was filled out for each flock, requesting data on the farm, the flock and the farmer by the veterinarians of the State Government Agency for Animal Health (Instituto Mineiro de Agropecuária). Thirteen important variables were selected and scored to determine the technological level of the 117 farms; 0.9% of them was classified as high technological level, 45.3% as medium technological level and 53.0% as low technological level. Lamb production was the main objective of the farms and the main features were low-frequencies of individual identification of animals (16.9%), technical assistance (31.9%), use of quarantine for newly acquired animals (0.9%) the separation of animals by age group (3.7%) and requeste the sanitary certificate at purchasing of animals (11.7%). The main health problems reported were abortion (23.9%), keratoconjunctivitis (17.9%), contagious ecthyma (13.6%), pneumonia (10.3%), diarrhea (9.3%) and caseous lymphadenitis (6.1%). Information of the epidemiological situation and the mainly health measures used in the sheep farms are important to improve the productivity and quality of the lamb.

Mathematical modeling of level of anaesthesia from EEG measurements

Problem of modeling of anaesthesia depth level is studied in this Master Thesis. It applies analysis of EEG signals with nonlinear dynamics theory and further classification of obtained values. The main stages of this study are the following: data preprocessing; calculation of optimal embedding parameters for phase space reconstruction; obtaining reconstructed phase portraits of each EEG signal; formation of the feature set to characterise obtained phase portraits; classification of four different anaesthesia levels basing on previously estimated features. Classification was performed with: Linear and quadratic Discriminant Analysis, k Nearest Neighbours method and online clustering. In addition, this work provides overview of existing approaches to anaesthesia depth monitoring, description of basic concepts of nonlinear dynamics theory used in this Master Thesis and comparative analysis of several different classification methods.

Relation between the level of self-mutilation and theconcentration of fecal metabolites of glucocorticoids incaptive chimpanzees (Pan troglodytes)

The influence of stress in an environment, according with the behavioral and endocrine variables of primates, are increasingly being studied by a diversity of authors, and have shown that abnormal behaviors associated with increased glucocorticoids may be directly related with the impairment of their well-being. In this work were used 22 adult chimpanzees (Pan troglodytes), 11 males and 11 females, kept in captivity in three different institutions. All animals had their behavior registered by focal session using a 30 seconds sample interval, during six months, totaling 4,800 registries per each animal. During this period, fecal samples were collected 3 times a week for the extraction and measurement of the concentration of fecal metabolites of glucocorticoid by radioimmunoassay. Of the total observed, stereotypical behaviors represented 13,45±2.76%, and among them, self-mutilation represented 38.28±3.98 %. The animals were classified into three different scores, according with the percentage of body surface with alopecia due to self-mutilation. It was found a positive correlation of high intensity between the scores of alopecia due to the observed mutilation and the average concentrations of fecal metabolites of glucocorticoids. This result strongly suggests that this measurement of self-mutilation in a chimpanzee can be used as an important auxiliary tool to evaluate de conditions of adaptation of an animal in captivity, functioning as a direct indicator of the presence of chronic stress.

Venäjän sotilasreformi : asevoimien uusi ilme

Tässä työpaperissa Venäjän sotilasreformin tarkastelu painottuu maavoimiin. Muista puolustushaaroista käsitellään lyhyesti meri- ja ilmavoimia. Lisäksi käsitellään koulutus, reservi ja mobilisaatio, johtaminen, toiminnan ulkoistaminen ja sosiaaliset kysymykset sekä asevoimien varustaminen. Julkaisun lähdemateriaali on lähes kokonaan venäjänkielistä. Sen avulla esitetään venäläisten omat niin myönteiset kuin kriittiset näkemykset koskien Venäjän asevoimien sotilasreformia, uutta ilmettä. Venäjänkielisistä termeistä käytetään mahdollisimman vastaavaa tai kuvaavaa suomenkielistä ilmaisua.

Low level resistance of goosegrass (Eleusine indica) to glyphosate in Rio Grande do Sul-Brazil

In the last growing seasons, goosegrass (Eleusine spp.) control failures have been observed following application of glyphosate on Roundup Ready® soybean in Rio Grande do Sul (RS) - Brazil, suggesting this species' resistance to the herbicide. Thus, the objectives of this study were to identify the occurrence of goosegrass resistance to the herbicide glyphosate in RS; and to determine the predominant species of the genus Eleusine, as well as the LD50 and GR50 of the suspected resistant biotypes. Two experiments were conducted under greenhouse conditions: one to identify the biotypes resistant to glyphosate, and the other, a dose-response curve experiment, as well as a study of the botanical characteristics of the species. In the first experiment, 39 biotypes were tested, mainly Eleusine indica, collected with suspected resistance to glyphosate. The glyphosate dose was 2,160 g e.a. ha-1, and the control was evaluated at 28 days after treatment. All biotypes were effectively controlled,with the biotypes from the municipality of Boa Vista do Incra showing greater tolerance. Two biotypes suspected of resistance (12.1 and 12.3) and a susceptible biotype in a dose-response experiment were tested at the following doses: 0, 135, 270, 540, 1,080, 1,620, and 2,160 g e.a. ha-1. The results of this experiment showed that biotype 12.1 does not present resistance to glyphosate and biotype 12.3 has a low level resistance since it is effectively controlled by the herbicide at the maximum dose.

Adaptive value of ryegrass biotypes with low-level resistance and susceptible to the herbicide fluazifop and competitive ability with the wheat culture

Ryegrass is the main weed in wheat crop, causing yield loss due to competition by environmental resources. The objectives of this study were to estimate the fitness cost of ryegrass biotypes with low-level resistance and susceptible to fluazifop and to investigate the relative competitive ability of these biotypes between themselves and against the crop. Thus, fitness cost and competitive ability experiments were conducted under greenhouse conditions. For the fitness cost experiments, the low-level resistant ryegrass biotypes and those susceptible to fluazifop were used. For competitive ability, the treatments were arranged in a replacement series, with five proportions of the wheat cultivar FUNDACEP Horizonte and the low-level resistant and susceptible ryegrass biotypes 100:0, 75:25, 50:50, 25:75 and 0:100. Competitive analysis was carried out through diagrams applied to the replacement experiments and use of relative competitiveness indices. Variables evaluated were plant height, in the fitness cost experiment, and leaf area and shoot dry biomass in both experiments. The ryegrass biotypes show overall similar fitness cost and competitive ability. The wheat cultivar FUNDACEP Horizonte is superior in competitive ability to the ryegrass biotype with low-level resistance and equivalent to the susceptible biotype.

Pojkar kan visst skriva! : skrivkompetenser på nationellt prov i svenska i årskurs tre i Sverige

10-year old boys are writing texts in a National Test in the spring of 2009. The aim of this study is to increase knowledge in and understanding of boys’ writing skills through description, analysis and interpretation of the texts produced by the boys in the National Test in Swedish for junior level year three, taken in Sweden in 2009. The material consists of texts produced by boys and is focused on their ability to write. Through avoiding relating to texts produced by girls, it is possible to search, review, interpret and observe without simultaneously comparing the two genders. The aim of the test is to measure writing proficiency from a normative perspective, while I am investigating content, reception, awareness, and other aspects relevant when producing text. Genres are described through the instruction given in the test, which defines the work that takes place in the classroom and thereby my approach to the analysis. The latter is focused on finding patterns in the competence of the students rather than looking for flaws and limitations. When competence is searched for beyond the relationship to syllabi or the demands of the test in itself, the boys’ texts from the test provide a general foundation for investigating writing proficiency. Person, place and social group have been removed from the texts thereby avoiding aspects of social positioning. The texts are seen from the perspective of 10-year old boys who write texts in a National Test. The theoretical basis as provided by Ivaničs (2004; 2012) offers models for theory on writing. A socio-cultural viewpoint (Smidt, 2009; Säljö, 2000) including literacy and a holistic view on writing is found throughout. By the use of abdicative logic (see 4.4) material and theory work in mutual cooperation. The primary method hermeneutics (Gadamer 1997) and analytical closereading (Gustavsson, 1999) are used dependent on the requirements of the texts. The thesis builds its foundation through the analysis from theoretically diverse areas of science. Central to the thesis is the result that boys who write texts in the National Test, are able to write in two separate genres without conversion or the creating hybrids between the two. Furthermore, the boys inhibit extensive knowledge about other types of texts, gained from TV, film, computers, books, games, and magazines even in such a culturally bound context as a test. Texts the boy has knowledge of through other situations can implicitly be inserted in his own text, or be explicitly written with a name of the main character, title, as well as other signifiers. These texts are written to express and describe what is required in the topic heading of the test. In addition other visible results of the boys’ ability to write well occur though the multitude of methods for analysis throughout the thesis which both search, and find writing competence in the texts written by the boys.

Complementarity of radioautographic and immunohistochemical techniques for localizing neuroreceptors at the light and electron microscopy level

To assess relationships between neuropeptide-binding sites and receptor proteins in rat brain, the distribution of radioautographically labeled somatostatin and neurotensin-binding sites was compared to that of immunolabeled sst2A and NTRH receptor subtypes, respectively. By light microscopy, immunoreactive sst2A receptors were either confined to neuronal perikarya and dendrites or diffusely distributed in tissue. By electron microscopy, areas expressing somatodendritic sst2A receptors displayed only low proportions of membrane-associated, as compared to intracellular, receptors. Conversely, regions displaying diffuse sst2A labeling exhibited higher proportions of membrane-associated than intracellular receptors. Furthermore, the former showed only low levels of radioautographically labeled somatostatin-binding sites whereas the latter contained high densities of somatostatin-binding suggesting that membrane-associated receptors are preferentially recognized by the radioligand. In the case of NTRH receptors, there was a close correspondence between the light microscopic distribution of NTRH immunoreactivity and that of labeled neurotensin-binding sites. Within the substantia nigra, the bulk of immuno- and autoradiographically labeled receptors were associated with the cell bodies and dendrites of presumptive DA neurons. By electron microscopy, both markers were detected inside as well as on the surface of labeled neurons. At the level of the plasma membrane, their distribution was highly correlated and characterized by a lack of enrichment at the level of synaptic junctions and by a homogeneous distribution along the remaining neuronal surface, in conformity with the hypothesis of an extra-synaptic action of this neuropeptide. Inside labeled dendrites, there was a proportionally higher content of immunoreactive than radiolabeled receptors. Some of the immunolabeled receptors not recognized by the radioligand were found in endosome-like organelles suggesting that, as in the case of sst2A receptors, they may have undergone endocytosis subsequent to binding to the endogenous peptide

”Kielestä kiinni”. Kuudesluokkalaisten maahanmuuttajaoppilaiden suomen kielen tason vaihtelut

Tämän tutkimuksen tarkoituksena on selvittää, minkälaista vaihtelua esiintyy maahanmuuttajaoppilaiden suomen kielen taidoissa peruskoulun kuudennella luokalla. Tutkimuksen tavoitteena on myös selvittää, minkälainen yhteys taustamuuttujilla (sukupuoli, äidinkieli, maahantuloikä, maahantulon syy, maassaoloaika ja vanhempien koulutausta) ja opetusjärjestelyillä, kuten perusopetukseen valmistavalla opetuksella, suomi toisena kielenä -opetuksella ja oman äidinkielen opetuksella, on suomen kielen taidon tasoon. Lisäksi tutkimuksen tavoitteena on selvittää oppilaan käyttämän kielen (suomen kieli ja äidinkieli) yhteyttä suomen kielen taidon tasoon. Tutkimusmetodina toimi mixed methods -tutkimus, ja tutkimuksen lähestymistapoja olivat kvantitatiivinen survey-tutkimus ja kvalitatiivinen sisällön analyysi. Tutkimukseen osallistui 219 maahanmuuttajaoppilasta 20:stä Turun koulusta. Tutkimusaineisto kerättiin Turun erityisopettajien ja suomi toisena kielenä -opettajien laatiman kielitestipaketin avulla. Oppilaan suullista ja kirjallista tuottamista arvioivat lasta opettavat opettajat eurooppalaisen viitekehyksen kielitaitotasojen kriteereitä käyttäen. Oppilaat arvioivat omaa äidinkielen ja suomen kielen taitoaan. Lisäksi oppilaat ja vanhemmat täyttivät tutkijan laatimat taustatietolomakkeet. Kielitestien tulosten mukaan oppilaista yli puolella oli tyydyttävä suomen kielen taito. Kaikista neljästä kielellisestä osiosta maahanmuuttajataustaiset oppilaat menestyivät parhaiten rakennekokeessa ja sanelussa, kun taas kuullun ja luetun ymmärtämisen tulokset olivat heikompia. Opettajien arviointien perusteella oppilaiden suulliset taidot vastasivat keskimäärin itsenäisen kielenkäyttäjän osaajan tasoa (B2) ja kirjoittamistaidot kynnystasoa (B1). Oppilaiden suomi toisena kielenä -arvosanan keskiarvo oli 7,26. Suomessa asumisen kestolla, maahantulon syyllä, äidinkielellä, maahantuloiällä, ja vanhempien koulutaustaustalla oli tilastollisesti merkitsevä yhteys suomen kielen taidon tasoon. Mitä kauemmin oppilaat olivat asuneet Suomessa ja mitä nuorempina he olivat tulleet Suomeen, sitä paremmin he menestyivät kielitesteissä. Paluumuuttajat menestyivät kielitaitotehtävissä kaikkein parhaiten ja pakolaiset heikoiten. Somalinkieliset erottuivat muista kieliryhmän edustajista heikoimpina suomen kielen taidon tasoltaan. Venäjänkieliset ja vietnaminkieliset saavuttivat parhaat tulokset kaikissa mittareissa. Erityisesti äidin korkeampi koulutustaso oli yhteydessä oppilaiden korkeampaan suomen kielen taidon tasoon. Oppilaat arvioivat suomen kielen taitonsa omaa äidinkieltään paremmaksi puhumisessa, lukemisessa ja kirjoittamisessa. Parhaiten eri mittareissa menestyivät oppilaat, jotka eivät olleet osallistuneet perusopetukseen valmistavaan opetukseen eivätkä erilliseen suomi toisena kielenä -opetukseen. Omaa äidinkieltään enemmän opiskelleet menestyivät kielitaitotehtävissä paremmin kuin vähän aikaa omaa äidinkieltään opiskelleet, mutta yhtä hyvin kuin ne, jotka eivät olleet opiskelleet omaa äidinkieltään lainkaan. Oppilaat, jotka puhuivat kaveriensa kanssa sekä omaa äidinkieltään että suomen kieltä, osoittautuivat kielitaidon tasoltaan paremmiksi kielitesteissä ja opettajien arvioinneissa.

Training graduate students to be teachers

Pedagogic education of graduate students, when and where it exists, is restricted to theoretical courses or to the participation of the students as teachers' assistants. This model is essentially reproductive and offers few opportunities for any significant curriculum innovation. To open an opportunity for novelty we have introduced a new approach in "Biochemistry Teaching", a course included in the Biochemistry Graduate Program of the Biochemistry Department (Universidade Estadual de Campinas and Universidade de São Paulo). The content of the course consists of a) choosing the theme, b) selecting and organizing the topics, c) preparing written material, d) establishing the methodological strategies, e) planning the evaluation tools and, finally, f) as teachers, conducting the course as an optional summer course for undergraduate students. During the first semester the graduate students establish general and specific educational objectives, select and organize contents, decide on the instructional strategies and plan evaluation tools. The contents are explored using a wide range of strategies, which include computer-aided instruction, laboratory classes, small group teaching, a few lectures and round table discussions. The graduate students also organize printed class notes to be used by the undergraduate students. Finally, as a group, they teach the summer course. In the three versions already developed, the themes chosen were Biochemistry of Exercise (UNICAMP), Biochemistry of Nutrition (UNICAMP) and Molecular Biology of Plants (USP). In all cases the number of registrations greatly exceeded the number of places and a selection had to be made. The evaluation of the experience by both graduate and undergraduate students was very positive. Graduate students considered this experience to be unique and recommended it to their schoolmates; the undergraduate students benefited from a more flexible curriculum (more options) and gave very high scores to both the courses and the teachers.
