The effect of chiropractic manipulation on the sacroiliac joints compared to mobilisation, on the weight distribution through the lower limbs
Sacro-iliac joint (S.I joint) dysfunction can result in leg length discrepancies (LLD). LLD has been associated with many musculoskeletal problems such as osteoarthritis of the hips, knee pain and lower back pain. It has been theorised that LLD alters a persons body posture, which in turn changes the forces acting on the joints in the lower extremity and spine. These unnatural forces then create the excessive forces seen as the causative factors in the previously mentioned musculoskeletal conditions. (Murrel, Cornwall, Doucet 1991) The purpose of this pilot study was to was to compare the effect of chiropractic manipulative therapy on the S.I joints with chiropractic mobilisations of the S.I joints on the weight transfer from the spine into the lower limbs. This randomised study consisted of two groups of fifteen patients between the ages of eighteen and fifty years. All potential candidates were examined and admitted once all the inclusion and exclusion criteria had been met. Once S.I joint restrictions were detected the patient received either chiropractic manipulation or mobilisation to the restricted joint. Group A received chiropractic manipulation while group B were treated with mobilisations of the S.I joints. Patients were treated over a two week treatment period. Objective measurements were taken before the 1st treatment and after the 1st ,3rd ,5th and final consultations one month later. The measurements were taken with the Spinal Analyses Machine (S.A.M). This instrument has got two scales on a platform that determines the patients weight distribution from the spine through the left and right lower limbs. The data collected was then statistically analysed using the One Way ANOVA Test (analyses of variance) as well as the Student-Newman-Keuls Method to compare the inter-group and intra-group data. Statistically significant changes in the weight distribution between the lower limbs were seen in group A. Based on the results from the study chiropractic manipulation to the S.I joint proved to be more effective than mobilisation in the treatment of S.I joint dysfunction. This does however require further research, and a larger sample size.Dr. M. Moodley Dr. J. Kotz

Static capacitive pressure sensing using a single graphene drum
To realize nanomechanical graphene-based pressure and gas sensors, it is
beneficial to have a method to electrically readout the static displacement of
a suspended graphene membrane. Capacitive readout, typical in
micro-electro-mechanical systems (MEMS), gets increasingly challenging as one
starts shrinking the dimensions of these devices, since the expected
responsivity of such devices is below 0.1 aF/Pa. To overcome the challenges of
detecting small capacitance changes, we design an electrical readout device
fabricated on top of an insulating quartz substrate, maximizing the
contribution of the suspended membrane to the total capacitance of the device.
The capacitance of the drum is further increased by reducing the gap size to
110 nm. Using external pressure load, we demonstrate successful detection of
capacitance changes of a single graphene drum down to 50 aF, and pressure
differences down to 25 mbar

THE POLITICAL ECONOMY OF FOOD PRICE INFLATION IN SOUTH AFRICA
This paper reports on a study that investigated the increase in food prices in South Africa. It is set against the scenario of an increasing inflation rate since September 2001. The June 2002 STATSSA figures estimated the annual inflation rate (CPIX) at 8.8% with food inflation being the major contributor with an annual increase of 14%. The high unemployment and poverty rate in South Africa has already lead to concerns about the negative impact of these increases on the cost of living for the poorest. In this paper we show that the sharp depreciation of the exchange rate towards the end of 2001 had a major impact on the producer price of maize one of the key agricultural commodities because of its role as a staple food and as an input in the production of white and red meat and other animal products.Demand and Price Analysis, Political Economy,

Combinatorics of Open Covers VI: Selectors for Sequences of Dense Sets
We consider the following two selection principles for topological spaces:
[Principle 1:] { For each sequence of dense subsets, there is a sequence of points from the space, the n-th point coming from the n-th dense set, such that this set of points is dense in the space;
[Principle 2:]{ For each sequence of dense subsets, there is a sequence of finite sets, the n-th a subset of the n-th dense set, such that the union of these finite sets is dense in the space.
We show that for separable metric space X one of these principles holds for the space C_p(X) of realvalued continuous functions equipped with the pointwise convergence topology if, and only if, a corresponding principle holds for a special family of open covers of X. An example is given to show that these equivalences do not hold in general for Tychonoff spaces. It is further shown that these two principles give characterizations for two popular cardinal numbers, and that these two principles are intimately related to an infinite game that was studied by Berner and Juhasz
