Impacts of grazing management options on pasture and animal productivity in a Heteropogon contortus (black speargrass) pasture in central Queensland. 4. Animal production.

Steer liveweight gains were measured in an extensive grazing study conducted in a Heteropogon contortus (black speargrass) pasture in central Queensland between 1988 and 2001. Treatments included a range of stocking rates in native pastures, legume-oversown native pasture and animal diet supplement/spring-burning pastures. Seasonal rainfall throughout this study was below the long-term mean. Mean annual pasture utilisation ranged from 13 to 61%. Annual liveweight gains per head in native pasture were highly variable among years and ranged from a low of 43 kg/steer at 2 ha/steer to a high of 182 kg/steer at 8 ha/steer. Annual liveweight gains were consistently highest at light stocking and decreased with increasing stocking rate. Annual liveweight gain per hectare increased linearly with stocking rate. These stocking rate trends were also evident in legume-oversown pastures although both the intercept and slope of the regressions for legume-oversown pastures were higher than that for native pasture. The highest annual liveweight gain for legume-oversown pasture was 221 kg/steer at 4 ha/steer. After 13 years, annual liveweight gain per unit area occurred at the heaviest stocking rate despite deleterious changes in the pasture. Across all years, the annual liveweight advantage for legume-oversown pastures was 37 kg/steer. Compared with native pasture, changes in annual liveweight gain with burning were variable. It was concluded that cattle productivity is sustainable when stocking rates are maintained at 4 ha/steer or lighter (equivalent to a utilisation rate around 30%). Although steer liveweight gain occurred at all stocking rates and economic returns were highest at heaviest stocking rates, stocking rates heavier than 4 ha/steer are unsustainable because of their long-term impact on pasture productivity.

Osseointegrated total knee replacement connected to a lower limb prosthesis: 4 cases

Background and purpose — Osseointegrated implants are an alternative for prosthetic attachment in individuals with amputation who are unable to wear a socket. However, the load transmitted through the osseointegrated fixation to the residual tibia and knee joint can be unbearable for those with transtibial amputation and knee arthritis. We report on the feasibility of combining total knee replacement (TKR) with an osseointegrated implant for prosthetic attachment. Patients and methods — We retrospectively reviewed all 4 cases (aged 38–77 years) of transtibial amputations managed with osseointegration and TKR in 2012–2014. The below-the-knee prosthesis was connected to the tibial base plate of a TKR, enabling the tibial residuum and knee joint to act as weight-sharing structures. A 2-stage procedure involved connecting a standard hinged TKR to custom-made implants and creation of a skin-implant interface. Clinical outcomes were assessed at baseline and after 1–3 years of follow-up using standard measures of health-related quality of life, ambulation, and activity level including the questionnaire for transfemoral amputees (Q-TFA) and the 6-minute walk test. Results — There were no major complications, and there was 1 case of superficial infection. All patients showed improved clinical outcomes, with a Q-TFA improvement range of 29–52 and a 6-minute walk test improvement range of 37–84 meters. Interpretation — It is possible to combine TKR with osseointegrated implants.

Superconformal transformations of theN = 2,D = 4, SSYM

We obtain the superconformal transformation laws for theN=2,D=4 SSYM. The transformations involve Yang-Mills fields and the corresponding field strength tensor is not constrained to be self antidual. We explicitly demonstrate the closure of the superconformal algebra.

Lukeminen ja kirjallisuus modernissa opiskeluympäristössä : Tapaustutkimus kuuden peruskoulun 4.-6. luokan telemaattinen kirjallisuuspiiri Matilda -hankkeesta

Tutkimuksen tavoitteena oli kartoittaa ja kehittää modernia opiskeluympäristöä hyödyntävää kirjallisuuspiiritoimintaa ja sitä kautta edistää oppilaiden mahdollisuuksia osallistua elämyksellistä lukemista painottavaan kirjallisuuspiiriin sekä vahvistaa heidän kiinnostustaan tieto- ja viestintätekniikan käyttöön. Tutkimusaineisto kerättiin lukuvuonna 1997 1998 kyselyin ja haastatteluin sekä observoimalla lähiopetustilanteita ja virtuaaliryhmien sähköpostiviestintää. Lisäksi käytettiin valmiita dokumentteja ja asiakirjoja. Tutkimusjoukkona oli Matildaan osallistuneet 4.-6. luokan oppilaat kuudelta Espoon ala-asteelta sekä neljä tutoria, koordinaattori ja joitakin luokanopettajia Matilda-kouluista. Tutkimusongelmat suuntautuivat pääasiassa matildalaisten kokemuksiin opiskelusta modernissa opiskeluympäristössä, suhteesta tieto- ja viestintätekniikkaan sekä siihen, mitä uutta lukemiseen ja kirjallisuuteen liittyvää he kertoivat oppineensa ja kokeneensa. Koska tutkimuskohteen kaltaisia kokeiluita, joissa yhdistyy kirjallisuuspiiritoiminta ja moderni tieto- ja viestintätekniikka, ei ainakaan Suomessa ole aikaisemmin ollut, päädyttiin tutkimusmetodologian valinnassa kvalitatiiviseen otteeseen. Tutkimusote noudatti tapaustutkimuksen ja kehittämistutkimuksen periaatteita. Vaikka tutkimus oli menetelmältään kvalitatiivinen, aineistoa käsiteltiin myös kvantifioiden, mutta yleistyksiä tehtiin ainoastaan tapauksen suuntaan. Tutkimustulokset osoittivat, että opiskelu oli oppilaille positiivinen kokemus. He pitivät erityisesti etäopiskelun itsenäisestä työskentelystä ja lähiopetuspäivistä. Heidän suhtautumisensa tieto- ja viestintätekniikkaan muuttui positiivisemmaksi ja heidän taitonsa tieto- ja viestintätekniikan käyttäjinä kehittyivät. Oppilaat saivat positiivisia lukukokemuksia, heidän lukualueensa laajeni ja osa heistä kertoi lukutyylinsä muutoksista ja syvenemisestä. Oppilaat kokivat ongelmallisimmaksi hankkeen sekavan tutorointi-systeemin, kiireisen aikataulun sekä tietokoneisiin ja -verkkoon liittyvät ongelmat. kirjallisuuspiiri, kolmilukutaito, lukutaito, kirjallisuus, lukeminen, elämyksellinenlukeminen, kirjallisuudenopetus, moderni opiskeluympäristö, avoin ja joustava opiskeluympäristö, telematiikka, tieto- ja viestintätekniikka reading circle, teaching of literature, tri-literacy, literacy, reading, literature, aestheticreading, modern learning enviroment, open anf flexible learning enviroment, telematics, modern information technology

Pyhä Kolminaisuus vai pilven reunalla istuva partasuu? : Jumalakuva evankelisluterilaisissa ja ortodoksissa 1.–4.-luokan uskonnon oppikirjoissa 1970–80- ja 2000-luvuilla

A concept of god is a wholeness that an individual experiences as God. The Christian concept of god is based on triune God: Father, Son, and the Holy Spirit. The concept of god is examined in different kinds of contexts particularly between the 1940's and the 1970's. Many researches of school books have widely been made in Finland, but, however, only a few from the point of view of the concept of god. Considering this, the concept of god in the school books of Evangelical Lutheran and Orthodox religion from first to fourth grade in 1970–80 and 2000 is examined in this survey. Additionally, the concept of god in curricula between years 1970 and 2004 is studied. The perspective on the concept of god is the change in the course of time and denominational emphasis. As a first hypothesis, God the Father is represented in books in 21st century as a kind and loving figure. As a second hypothesis, the Trinity and the Holy Spirit get more space in Orthodox books comparing with the Lutheran books. Twelve school books of Evangelical Lutheran and Orthodox religion from first to fourth grade were used as a research material. The books were from four different series between the years 1978 and 2005. Teacher's guidebooks and student's exercise books were left outside of this survey. The research material was analyzed by using abductive content analysis and methodological triangulation. This study included both qualitative and quantitative aspects. The classification system which defined the classifying of concept of god from the research material was consisted of the basis of research material, former reseach, and subtext of used theories. The number of mentions in concept of god was higher in books from the 21st century. In Lutheran books, the change was seen as a growth of the category of God the Father. In Orthodox books, the trend was opposite: the category of Jesus the Son had grown. Differing from the presupposition, the features of loving God in new books had less emphasis than in older books in both churces. The mentions of the Holy Spirit and Trinity were marginal. In the Orthodox books, the categories were bigger, as it was presupposed. It could be seen, that the books confirmed the legalistic period of the concept of god on 3rd and 4th grades. The mentions of concept of god in curriculas have diminished and generalized. The diminution was seen most radically in the curriculum from the year 1994. The results tell something about social changes and views of innovation in curricula. In books the change was not perceived that bright. The idea of the concept of god getting shrank and decreased during the time can be refused.

New Modified Dipping Method Using 4-hexylresorcinol for Preventing Blackspot Formation in Prawns.

Industry acceptance of alternative sulphite treatments for preventing blackspot in prawns is limited. This study demonstrated that dipping prawns (Penaeus monodon and Fenneropenaeus merguiensis) in a less concentrated solution for longer times provides better control of blackspot formation than the recommended 2 minute dip in 50 mg/L 4-hexylresorcinol. Protection improved as modified dipping times and solution concentrations increased. Blackspot protection provided by most of the modified dip methods was more effective than a 1 minute dip in 1% sodium metabisulphite. The recommended 2 minute dip method should be limited to 125 kg when used on consecutive 25-kg batches of prawns. Yields increased by less than 10% even after 72-hour exposure in the modified dip. The new dipping method meets most international residue standards when applying the modified treatments evaluated.

Synthesis and biological evaluation of novel 1-(4-methoxyphenethyl)-1H-benzimidazole-5-carboxylic acid derivatives and their precursors as antileukemic agents

We report here the synthesis and preliminary evaluation of novel 1-(4-methoxyphenethyl)-1H-benzimidazole-5-carboxylic acid derivatives 6(a–k) and their precursors 5(a–k) as potential chemotherapeutic agents. In each case, the structures of the compounds were determined by FTIR, 1H NMR and mass spectroscopy. Among the synthesized molecules, methyl 1-(4-methoxyphenethyl)-2-(4-fluoro-3-nitrophenyl)-1H-benzimidazole-5-carboxylate (5a) induced maximum cell death in leukemic cells with an IC50 value of 3 μM. Using FACS analysis we show that the compound 5a induces S/G2 cell cycle arrest, which was further supported by the observed down regulation of CDK2, Cyclin B1 and PCNA. The observed downregulation of proapoptotic proteins, upregulation of antiapoptotic proteins, cleavage of PARP and elevated levels of DNA strand breaks indicated the activation of apoptosis by 5a. These results suggest that 5a could be a potent anti-leukemic agent.
