Isolation And Identification Of Solasodine From The Fruit Of Solanum Melongena L.
This research was aimed at isolating solasodine from the fruit of Solanum melongena L. and identifying the product of isolation. The isolation was performed initially by direct method steam distillation followed by reflux with concentrated hydrochloric acid to extract the intended substance. Identification of the product was conducted using color test with sulfuric acid (H2SO4), color test according to Briggs and Salkowski, thin layer chromatography (TLC), and Fourier transform−infrared spectrophotometry (FTIR). The reaction of the product and H2SO4 gave a brown coloration, while the result of TLC demonstrated a brown spot with retardation factor (Rf) similar to that of standard solasodine, and the IR spectrum showed peaks similar to those of standard. These results confirmed that solasodine existed in the extract of Solanum melongena L.s fruit and therefore direct method live steam distillation followed by reflux can be used to isolate solasodine from the fruit
E-portfolio thinking in teacher training: a small-scale study in K-12 in Turkey
The account given in this paper is related to the experiences of foreign language teachers involved in the pilot study undertaken in a high school in Turkey. After outlining the distinctive advantages of e-portfolios in the context of teacher development; this paper discusses the results of a qualitative study addressing the value of e-portfolios as versatile teaching and learning tools to showcase the professional skills of the teachers. Data collection was undertaken through both semi-structured interviews with the majority of these teachers and field observations. By providing teachers with the opportunity to enhance their technological skills and to reflect critically upon their work as educators, e-portfolios can serve as an invaluable resource for meeting educational standards and promoting effective teaching practice

Hiddleston’s Causal Modeling Semantics and the Distinction between Forward-Tracking and Backtracking Counterfactuals
Some cases show that counterfactual conditionals (‘counterfactuals’ for short) are inherently ambiguous, equivocating between forward-tracking and backtracking counterfactu- als. Elsewhere, I have proposed a causal modeling semantics, which takes this phenomenon to be generated by two kinds of causal manipulations. (Lee 2015; Lee 2016) In an important paper (Hiddleston 2005), Eric Hiddleston offers a different causal modeling semantics, which he claims to be able to explain away the inherent ambiguity of counterfactuals. In this paper, I discuss these two semantic treatments and argue that my (bifurcated) semantics is theoretically more promising than Hiddleston’s (unified) semantics
Remote control of devices using an 8-bit embedded XML & dynamic web-server in a SmartHouse environment : a thesis presented in partial fulfilment of the requirements for the degree of Master of Engineering in Computer Systems Engineering at Massey University
This paper focuses on an Embedded System known as "TCP/IC" and its role in the "house of the future" - the SmartHouse. Overall, the aim of the TCP/IC was to design a device which could interact with a user (or AI control system) and allow for the control of various attached peripherals remotely. Although such a device could well be used as a standalone device to aid in home-automation, this paper focuses on its use in a SmartHouse environment - one where a number of these devices are networked and controlled by a central AI. The different technologies and protocols involved in the implementation of the TCP/IC, along with its two primary interfaces, namely HTML (used for user interaction) and XML (used for machine interaction) are also discussed. The reader will also be introduced to Embedded Systems and the various design principles involved in the creation of quality Embedded Systems. Core-concepts of home-automation and its logical extension, the SmartHouse are also covered in detail. Various additional interfaces (e.g. Web, XML, custom-formatted text) are also discussed and compared, as are the result of my work and some ideas for future implementations
