Abstract The augmentative and alternative communication (AAC) personnel framework identifies the various types of people involved in successful AAC interventions. The purposes of this article are to summarize information in the AAC intervention literature that documents the role and impact of various AAC personnel, describe key characteristics of adult learners, and review research that focuses on learning motivations and preferences of adults within the AAC framework.

Global Problems

The coordination of economic activity at the global level is carried out through different mechanisms, which regulate activities of companies, states, international organizations. In spite of wide diversity of entrenched mechanisms of governance in different areas, they can be classified on the basis of key characteristics, including distribution of property rights, mechanisms of governance (in the narrow sense according to O. Williamson), mechanisms of expansion. This approach can contribute not only to classifying existing institutions but also to designing new ones. The modern aggravation of global problems may require rethinking mechanisms of global governance. The authors offer the universal framework for considering this problem and its possible solutions.

The One of alternative energy that is environmentally friendly is by untilize water energy and turn it into a Microhydro power plant. Microhydro power plant usually made from utilize the waterfall with the head fell. While utilization for streams with a head small drop is not optimal yet. This is a reference to doing research on harnessing the flow of a river that has a value of head low between 0.7 m – 1.4 m with turning it into a Vortex flow (vortex). The purpose of this research is to know  the effect variation number of blade on power and efficiency in the vortex turbine. This research uses experimental methods to find current, voltage, torque and rpm using a reading instrument. The materials research vortex turbine used 6 blade, 8 blade and 10 blade with flat plate. The result showed the highest efficiency is 29,93 % with produce turbine power is 19,58 W, generated on turbine with variation 10 blade with load 3,315 kg and the capacity of water 10,14 l/s. Followed with an efficiency 24,17% and produce turbine power is 15,81 W, generated on turbine with the variation 8 blade with load 3,315 kg and the capacity of water is 10,14 l/s. The the lowest turbine efficiency 22,32% with produce tuebine power 14,60 W, generated on turbine with the variation 6 blade with load 3,315 kg, the capacity of water is 10,14 l/s.

AbstractThe bias voltage dependent spectral response (with and without steady state bias light) and the current voltage dependence has been simulated and compared to experimentally obtained values. Results show that in the heterostructures the bias voltage influences differently the field and the diffusion part of the photocurrent. The interchange between primary and secondary photocurrent (i. e. between generator and load device operation) is explained by the interaction of the field and the diffusion components of the photocurrent. A field reversal that depends on the light bias conditions (wavelength and intensity) explains the photocurrent reversal. The field reversal leads to the collapse of the diode regime (primary photocurrent) launches surface recombination at the p-i and i-n interfaces which is responsible for a double-injection regime (secondary photocurrent). Considerations about conduction band offsets, electrical field profiles and inversion layers will be taken into account to explain the optical and voltage bias dependence of the spectral response.
