Travelling drum with different beats: experiencing African music and culture in Australian teacher education

This article reports on a study that examined the effectiveness of introducing African music and culture to Australian non-specialist primary teacher education students at Deakin University in Melbourne (Australia). The study demonstrates that African music enhanced the generic musical experiences, learning, motivation, interest, confidence and competence of students in their fourth year of teacher education. The research also addressed the significance and contribution of African music and culture as a cross-cultural experience for these beginning teachers who in turn could provide similar experiences for their own students. This study highlighted the author's role and cultural identity as a South African music educator in transmitting the music and culture represented in 'the travelling drum' to a cohort of students with a predominantly Eurocentric orientation. By extension, this curriculum initiative broadened students' understanding and application of indigenous methods of teaching and learning as part of a global experience. Such a curriculum represents a pathway to many other forms of non-Western indigenous knowledge of music, culture and pedagogy that can be mapped out as a journey along a multicultural route towards 'internationalising the curriculum'.

Rapid multi sample DNA amplification using rotary-linear polymerase chain reaction device (PCRDisc)

Multiple sample DNA amplification was done by using a novel rotary-linear motion polymerase chain reaction (PCR) device. A simple compact disc was used to create the stationary sample chambers which are individually temperature controlled. The PCR was performed by shuttling the samples to different temperature zones by using a combined rotary-linear movement of the disc. The device was successfully used to amplify up to 12 samples in less than 30 min with a sample volume of 5 μl. A simple spring loaded heater mechanism was introduced to enable good thermal contact between the samples and the heaters. Each of the heater temperatures are controlled by using a simple proportional–integral–derivative pulse width modulation control system. The results show a good improvement in the amplification rate and duration of the samples. The reagent volume used was reduced to nearly 25% of that used in conventional method.

Hexameric isopropyloxotin acetate chloroform tetrasolvate

The molecular structure of the centrosymmetric hexanuclear title compound, [ⁱPrSn(O)(O₂CCH₃)]₆·4CHCl1₃ or [Sn₆O₆(C₃H₇)₆(C₂H₃O₂)₆]·4CHCl₃, adopts the `drum' motif, in which two (ⁱPrSnO)₃ caps are linked via six ^μ₃-oxo atoms and six acetate groups. The Sn atoms are in distorted octahedral environments, defined by a CO₅ donor set for each of the three independent Sn atoms.

Hexameric trimethylsilylmethyloxotin acetate, [(Me3SiCH2)Sn(O)(OAc)]6

The centrosymmetric hexanuclear title compound, hexa-^μ₂-acetato-hexa-^μ₃-oxo-hexakis[(trimethylsilylmethyl)tin], [Sn₆O₆(C₂H₃O₂)₆(C₄H₁₁Si)₆], adopts a 'drum' structure in which two [(Me₃SiCH₂)SnO]₃ caps are linked to each other via six ^μ₃-O atoms and six bidentate bridging acetate groups. A CO₅ donor set defines a distorted octahedral environment for each of the three independent Sn atoms.

Simulation-based support tool for operator performance in batch manufacturing

In industry, the workload and utilization of shop floor operators is often misunderstood. In this paper, we will present several real case studies, using Discrete Event Simulation (DES) models, which allow us to better understand operators in a batch manufacturing environment. The first study investigates labour in a machining plant consisting of multiple identical CNC machines that batch produce parts. The second study investigates labour in an eight station, gravity die casting rotary table. The results from these studies have shown that there can be potential improvements made by the production planners in the current labour configuration. In the first case study, a matrix is produced that estimates what the operator's utilization levels will be for various configurations. From this, the preferred operator to machine ratio over a range of cycle times is presented. In the second study, the results have shown that by reducing the casting cycle time, the operator would be overloaded. A discrete event simulation of these two cases highlighted areas that were misunderstood by plant management, and provided them with a useful decision support tool for production planning.

Thermal evaluation of a low cost wood burner

Small-scale producers of dried products in rural areas of developing countries must often rely on sun drying to dry their crops, but this can be unreliable and produce an inferior product. There is therefore a need for simple and inexpensive combustion devices that can be fabricated and used locally. A wood burner has been constructed from a "200 litre" steel drum and has then been evaluated experimentally. The thermal efficiency of the burner was found to be 31% in two trials. An energy balance, calculated for three trials, was within + 16%. Approximately one third of the energy available in the wood was lost in the flue gases, either as sensible heat or unburned volatile gases. Excess combustion air through the burner was calculated and measured to be approximately 400% of the stoichiometric requirements. A significant amount of energy was required to heat the thermal mass surrounding the burner, indicating that a lightweight insulated structure would be more suitable in most circumstances.

Women, religion and social change in the Philippines : refractions of the past in urban filipinas' religious practices today

This research is an exploration of the place of religious beliefs and practices in the life of contemporary, predominantly Catholic, Filipinas in a large Quezon City Barangay in Metro Manila. I use an iterative discussion of the present in the light of historical studies, which point to women in pre-Spanish ‘Filipino’ society having been the custodians of a rich religious heritage and the central performers in a great variety of ritual activities. I contend that although the widespread Catholic evangelisation, which accompanied colonisation, privileged male religious leadership, Filipinos have retained their belief in feminine personages being primary conduits of access to spiritual agency through which the course of life is directed. In continuity with pre-Hispanic practices, religious activities continue to be conceived in popular consciousness as predominantly women’s sphere of work in the Philippines. I argue that the reason for this is that power is not conceived as a unitary, undifferentiated entity. There are gendered avenues to prestige and power in the Philippines, one of which directly concerns religious leadership and authority. The legitimacy of religious leadership in the Philippines is heavily dependent on the ability to foster and maintain harmonious social relations. At the local level, this leadership role is largely vested in mature influential women, who are the primary arbiters of social values in their local communities. I hold that Filipinos have appropriated symbols of Catholicism in ways that allow for a continuation and strengthening of their basic indigenous beliefs so that Filipinos’ religious beliefs and practices are not dichotomous, as has sometimes been argued. Rather, I illustrate from my research that present day urban Filipinos engage in a blend of formal and informal religious practices and that in the rituals associated with both of these forms of religious practice, women exercise important and influential roles. From the position of a feminist perspective I draw on individual women’s articulation of their life stories, combined with my observation and participation in the religious practices of Catholic women from different ethnic and socio-economic backgrounds, to discuss the role of Filipinas in local level community religious leadership. I make interconnections between women’s influence in this sphere, their positioning in family social relations, their role in the celebration of All Saints and All Souls Days in Metro Manila’s cemeteries and the ubiquity and importance of Marian devotions. I accompany these discussions with an extensive body of pictorial plates.

Drehschieberventil fuer ein Kraftfahrzeug

The valve has a sealing unit arranged proximate to a rotary body. The sealing unit is arranged with a flexible sealing lip (6) in such a manner that the lip in a closed position of the valve is brought into a position resting against the body by pressurization of a combustion chamber. The sealing unit is provided with an under cut (8), where section of the under cut regions lying near the chamber forms the lip. An independent claim is also included for a method for intake and/or exhaust of gases in an internal combustion engine.
