Serum Lipid Profile and Retinol in Rats Fed Micronutrient Rich Edible Vegetable Oil Blend

Khan HN, Farooqi H, Ali S, Khan JS. 2010. Serum lipid profile and retinol in rats fed micronutrient rich edible vegetable oilblend. Nusantara Bioscience 2: 109-116. The animal rats were given 10% oil mixed in fat free diet for one month or six months. In theexperiment, the groups of rats were fed with the micronutrient (MN) rich blends mixed previously with 1% cholesterol, and their effectswere tested on serum lipid profile. Most significant changes in the High Dencity Lipoprotein (HDL) cholesterol were observed in onemonthstudy where HDL increased from 24 mg/dl in group to 64 mg/dl in the Mustard palm olein oil blend (MP); in mustard oil (MO)alone fed rats, the HDL was 36 mg/dl. Serum retinol was analyzed as one of the important MN in rats receiving the diet mixed with theblend for various duration of time. The results assume great significance as MO or palm olein oil (PO) alone could not bring themaximum beneficial effects, and the blends appear to have more merit as health oils in alleviating adverse health condition such ascoronary heart disease (CHD), diabetes, obesity and hypertension

The design of IPT system for multiple kitchen appliances using class E LCCL circuit

Since many years ago, kitchen appliances are powered up by cable connected. This create a troublesome case as wire might tangle together and cause kitchen table messy. Due to this, wireless power technology (WPT) is introduced as its ability is to transmit power to load without physical contact. This leads to cordless solution better in safety as the product can be completely seal, highly expandable power range. This work focuses on the design of WPT based on inductive approach to power up multiple kitchen appliances. The selection of inductive approach over its partners capacitive and acoustic is mainly due to high power efficiency. Class E inverter is proposed here to convert the DC to AC current to drive the inductive link. A 1 MHz operating frequency is used. To ensure the circuit is robust with load variations, an LCCL impedance matching is proposed. This solution is table to maintain the output power if there is a slight change in load impedance. Finally, the developed prototype is able to supply 50V utput which can achieve power transmission up to 81.76%

Sliding Mode Observer Based Controller for Active Steering Control

The purpose of this paper is to enhance the performance of steering control of a vehicle. A nonlinear sliding mode observer based active steering controller that will overcome the disturbances such as road condition and crosswind is proposed. Condition of stability is given by using Lyapunov stability theory that relates to sliding mode characteristics. The controller proves that it is able to stabilize the steering wheel better when disturbances such as braking action and crosswind are included in the system. Lastly, simulations are given to prove the validity of the controller stability. In the simulations, comparisons are made between the outcome of the uncontrolled, Linear Quadratic Regulator (LQR), Sliding Mode Controller (SMC) and Sliding Mode Observer Based Controller (SMOC)

The Relativistic Linear Singular Oscillator

Exactly-solvable model of the linear singular oscillator in the relativistic configurational space is considered. We have found wavefunctions and energy spectrum for the model under study. It is shown that they have correct non-relativistic limits.Comment: 14 pages, 12 figures in eps format, IOP style LaTeX file (revised taking into account referees suggestions

The Rac GTP Exchange Factor TIAM-1 Acts with CDC-42 and the Guidance Receptor UNC-40/DCC in Neuronal Protrusion and Axon Guidance

The mechanisms linking guidance receptors to cytoskeletal dynamics in the growth cone during axon extension remain mysterious. The Rho-family GTPases Rac and CDC-42 are key regulators of growth cone lamellipodia and filopodia formation, yet little is understood about how these molecules interact in growth cone outgrowth or how the activities of these molecules are regulated in distinct contexts. UNC-73/Trio is a well-characterized Rac GTP exchange factor in Caenorhabditis elegans axon pathfinding, yet UNC-73 does not control CED-10/Rac downstream of UNC-6/Netrin in attractive axon guidance. Here we show that C. elegans TIAM-1 is a Rac-specific GEF that links CDC-42 and Rac signaling in lamellipodia and filopodia formation downstream of UNC-40/DCC. We also show that TIAM-1 acts with UNC-40/DCC in axon guidance. Our results indicate that a CDC-42/TIAM-1/Rac GTPase signaling pathway drives lamellipodia and filopodia formation downstream of the UNC-40/DCC guidance receptor, a novel set of interactions between these molecules. Furthermore, we show that TIAM-1 acts with UNC-40/DCC in axon guidance, suggesting that TIAM-1 might regulate growth cone protrusion via Rac GTPases in response to UNC-40/DCC. Our results also suggest that Rac GTPase activity is controlled by different GEFs in distinct axon guidance contexts, explaining how Rac GTPases can specifically control multiple cellular functions
