Procurement function is a facilitator and enabler of every value chain. This paper is a result of a study on the contribution of procurement function on the public services delivery systems and on the national socio-economic development. Specific foci were on: assessing the contribution of procurement function on the public services delivery systems; and assessing the contribution of procurement function on the attainment of the objectives of the national socio-economic development. The study used a survey of value-laden opinions. Localities surveyed were deliberately selected and sampled. The study covered one metropolis and business city (Dar es Salaam), three regional administrative cities (Arusha, Mbeya and Mwanza), one central government municipal (Dodoma), and one local municipal council (Morogoro). A deliberate sample of 150 case respondents was envisaged. However, the study covered 129 case respondents. Data management and analysis were qualitative in which thematic analysis, documentary reviews and content analysis were applied upon the specific study objectives.  This paper provides value-laden opinions generated out of the case respondents’ perceptions on the specific themes and issues related thereto. The results of assessment show a significant contribution of the procurement function on the Tanzania public services delivery systems and on the national socio-economic development agenda. The assessments show a positive marginal contribution of the procurement functional performance on the national economic development agenda by more than 70%.

The use of various bioerodable polymers as drug delivery systems has gained considerable interest in recent years. Among some of the shapes used as delivery systems are films, rods and microcapsules. The work presented here will deal with the techniques we have utilized for the analysis of the tissue reaction to and actual biodegradation of injectable microcapsules. This work has utilized light microscopic (LM), transmission (TEM) and scanning (SEM) electron microscopic techniques. The design of our studies has utilized methodology that would; 1. best characterize the actual degradation process without artifacts introduced by fixation procedures and 2. allow for reproducible results.In our studies, the gastrocnemius muscle of the rat was chosen as the injection site. Prior to the injection of microcapsules the skin above the sites was shaved and tattooed for later recognition and recovery. 1.0 cc syringes were loaded with the desired quantity of microcapsules and the vehicle (0.5% hydroxypropylmethycellulose) drawn up. The syringes were agitated to suspend the microcapsules in the injection vehicle.

The Audiokinetron is a device that processes music for earphone presentation to patients undergoing auditory integration training, a treatment for individuals with autism and other developmental disabilities. Intensity levels produced by the Audiokinetron were measured under realistic listening conditions with a KEMAR manikin substituted for a patient. Average levels at the eardrum were 110 dB SPL when the device was adjusted to the highest setting employed by a local, trained AIT practitioner and 118 dB SPL at the maximum setting of the device. These levels are potentially harmful to hearing and warrant further safety studies of AIT instruments and protocols.
