On the Interflecton Concerning Fluorescent Lamp (Part II)

On a Conjecture Concerning the Petersen Graph: Part II

Robertson conjectured that the only 3-connected, internally 4-connected graph of girth 5 in which every odd cycle of length greater than 5 has a chord is the Petersen graph. We provide a counterexample to this conjecture.

The effect of compact fluorescent lamp and curcumin on wound healing in Wistar Rats

Background: Nowadays, the rapid recovery of skin lesions and functional return are among the goals of researchers. The skin is the first defensive barrier against microorganisms in the body and its failure causes infection to spread in all systems of the body. By taking into account the contradictory results of previous studies on the impact of phototherapy on wound healing and also the conside...

Fiat Lux: A Fluorescent Lamp Tkansceiver

The prevalence of electric discharge illumination has led us to consider ways to use discharge lamps for communication. This paper describes an optical transceiver system which transmits by modulating the lamp arc. The prototype power electronic lamp ballast uses a pulse frequency modulation scheme which ensures no perceptible flicker.

Fluorescent Lamp Modelling for Voltage Fluctuations

Preparation of the Phencyclidine Analogues (Part II)

Using a-tetralone, as starting material, a series of phencyclidine analogues were synthesized. This ketone was reacted separately with ethylmagnesium bromide, P-methoxyphenylmagnesium bromide and P-methylphenylmagnesium bromide. The resultant alcohols were treated with a suspension of NaN3 and CCl3COOH in CHCl3. The azides were subsequently...
