Omat rummut tutuiksi: tutkimus rumpukalvojen ja virittämisen vaikutuksesta rumpusoundiin

Tämän työn tavoite oli selvittää miten rumpukalvoilla ja virittämisellä voidaan vaikuttaa rumpujen soundiin. Voiko samasta rumpusetistä saada hyvän soundin niin rockin kuin jazzinkin soittoon? Miten kannattaa menetellä jos konsertissa soitetaan tyyliltään hyvin erilaisia kappaleita? Lähtökohtana oli yksi rumpusetti jolla testattiin neljäkymmentäyksi uutta rumpukalvoa erilaisin virein. Kaikki kokeilut tehtiin studiossa ja niistä äänitettiin näytteet. Miri Miettinen toimi yhteistyökumppanina käytännön studiotyössä toimien äänittäjänä sekä toi pidemmän kokemuksen tuomaa osaamista virittämiseen. Kirjoitin aiheesta tiivistetyn artikkelin Riffi-lehteen. Artikkeli on julkaistu numerossa 4/2006. Lehti on liitteenä työssä. Tämä soveltava tutkimus voi olla myös esimerkki muille kuinka perehtyä omiin rumpuihinsa. Empiirinen kokemus tällaisesta työsta helpottaa toimintaa rumpalina. Rummut saa nopeammin ja helpommin kuulostamaan siltä kuin pitäisi. Tulos-osiossa käsitellään rumpujen virittämistä. Tutkimuksen myötä tulin tulokseen että käytettävä rumpukalvo antaa soundille ominaisen sävynsä, virityksellä se saadaan kuulostamaan musiikkityyliin sopivalta. Jotkut kalvot soveltuvat ominaisuuksiensa puolesta tiettyyn tyylin paremmin kuin toiset. Rumpujen virittämisen lisäksi tulos-osion kolme tärkeintä pääryhmää ovat pop/rock -soundi, jazz-soundi ja all-around -soundi. Niissä pohditaan soundia historian merkittävien rumpalien kautta. Jokaiseen pääryhmään kuuluu näyte-osio jossa esitellään tutkimuksessa saatuja tuloksia. Kahta saman kuuloista kalvoa ei tullut vastaan, toisin sanoen kalvot vaikuttaa merkittävästi rumpujen soundiin. Työn mukana on näyte-cd jolta voi kuunnella kaikki ääninäytteet. Raitalistan avulla jokainen voi vertailla kalvoja mieleisessään järjestyksessä. Kuuntelemalla samalla viretasolla tehtyjä eri kalvojen näytteitä peräkkäin, kuulee selkeästi niiden soundien eron.

Nos hemos quedado sin energía : Les Alqueries, solidaridad y energías alternativas.

A través de un juego de simulación, 28 alumnos de 1õ de ESO desarrollan un proyecto en el que proponen soluciones de emergencia ante una situación en la que el pueblo se ha quedado totalmente aislado del exterior, sin energía ni agua corriente. Tras plantear salidas viables para superar la crisis, la experiecia concluye con la estancia durante una semana en uno de los centros rurales en materia de energías alternativas, el Mas de Noguera. Se concluye que es necesario hacer un uso correcto de la energía, sustituyendo hábitos consumistas..

Does more detailed information mean better performance? An experiment in information explicitness

Purpose – Investors are now able to analyse more noise-free news to inform their trading decisions than ever before. Their expectation that more information means better performance is not supported by previous psychological experiments which argue that too much information actually impairs performance. The purpose of this paper is to examine whether the degree of information explicitness improves stock market performance. Design/methodology/approach – An experiment is conducted in a computer laboratory to examine a trading simulation manipulated from a real market-shock. Participants’ performance efficiency and effectiveness are measured separately. Findings – The results indicate that the explicitness of information neither improves nor impairs participants’ performance effectiveness from the perspectives of returns, share and cash positions, and trading volumes. However, participants’ performance efficiency is significantly affected by information explicitness. Originality/value – The novel approach and findings of this research add to the knowledge of the impact of information explicitness on the quality of decision making in a financial market environment.

Structure of weakly bonded PPG-silica nanocomposites

The structure of silica-polypropyleneglycol (PPG) nanocomposites with weak physical bonds between the organic (PPG) and inorganic (silica) phase, prepared by the sol-gel process, was investigated by small angle X-ray scattering (SAXS). These nanocomposite materials are transparent, flexible, have good chemical stability and exhibit high ionic conductivity when doped with lithium salt. Their structure was studied as a function of silica weight fraction x (0.06 less than or equal to x less than or equal to 0.29) and [O]/[Li] ratio (oxygens being of ether-type). The shape of the experimental SAXS curves agrees with that expected for scattering intensity produced by fractal aggregates sized between 30 and 90 Angstrom. This result suggests that the structure of the studied hybrids consists of silica fractal aggregates embedded in a matrix of PPG. The correlation length of the fractal aggregates decreases and the fractal dimension increases for increasing silica content. The variations in structural parameters for increasing Li+ doping indicate that lithium ions favor the growth of fractal silica aggregates without modifying their internal structure and promote the densification of the oligomeric PPG matrix.

Sustentabilidade nas organizações: a internalização dos gastos com o descarte do produto e/ou embalagem aos custos de produção

Neste estudo, tem-se como objetivo analisar e discutir crenças, valores e aspectos práticos, considerando que a internalização dos gastos decorrentes do descarte do produto e/ou embalagens deve nortear a gestão de custos de produção de uma empresa. Por tratar-se de área do conhecimento ainda carente de estudos e sem solução consensual por parte de agentes do mercado, realizou-se um ensaio teórico em que são apresentados e discutidos posicionamentos, práticas e ações com potencial para mitigar os efeitos da degradação ambiental decorrentes de descartes inapropriados. Para isso são propostas ações por parte de empresas e de iniciativas voluntárias em negociações de títulos financeiros de compensação das externalidades, os quais foram denominados de créditos de internalização de custos privados (CICPs). Considera-se que o desenvolvimento com sustentabilidade é um processo que envolve negociações entre empresas, governos e sociedade civil, pois as políticas e metas não devem ser apenas economicamente viáveis, mas socialmente justas, ambientalmente corretas e culturalmente compartilhadas.

A complementary radiographic projection of the equine temporomandibular joint

The complexity of the equine skull makes the temporomandibular joint a difficult area to evaluate radiographically. The goal of this study was to determine the optimal angle for a complementary radiographic projection of the equine temporomandibular joint based on a computed tomography (CT) cadaver study. CT was performed on six equine cadaver heads of horses that were euthanized for other reasons than temporomandibular joint disease. After the CT examination, 3D reconstruction of the equine skull was performed to subjectively determine the angle for a complementary radiographic projection of the temporomandibular joint. The angle was measured on the left and right temporomandibular joint of each head. Based on the measurements obtained from the CT images, a radiographic projection of the temporomandibular joint in a rostra-145 degrees ventral-caudodorsal oblique (R45 degrees V-CdDO) direction was developed by placing the X-ray unit 30 degrees laterally, maintaining at the same time the R45 degrees V-CdDO angle (R45 degrees V30 degrees L-CdDLO). This radiographic projection was applied to all cadaver heads and on six live horses. In three of the live horses abnormal findings associated with the temporomandibular joint were detected. We conclude that this new radiographic projection of the temporomandibular joint provides superior visualization of the temporomandibular joint space and the articular surface of the mandibular condyle.

NDT to identify biological damage in wood

Nondestructive techniques are widely used to assess existing timber structures. The models proposed for these methods are usually performed in the laboratory using small clear wood specimens. But in real situations many anomalies, defects and biological damage are found in wood. In these cases the existing models only indicate that the values are outside normality without providing any other information. To solve this problem, a study of non-destructive probing methods for wood was performed, testing the behaviour of four different techniques (penetration resistance, pullout resistance, drill resistance and chip drill extraction) on wood samples with different biological damage, simulating an in-situ test. The wood samples were obtained from existing Spanish timber structures with biotic damage caused by borer insects, termites, brown rot and white rot. The study concludes that all of the methods offer more or less detailed information about the degree of deterioration of wood, but that the first two methods (penetration and pullout resistance) cannot distinguish between pathologies. On the other hand, drill resistance and chip drill extraction make it possible to differentiate pathologies and even to identify species or damage location. Finally, the techniques used were compared to characterize their advantages and disadvantages.
