Bagger-Lambert-Gustavsson theory with infinite dimensional gauge group has been suggested to describe M5-brane as a condensation of multiple M2-branes. Here we perform a topological twisting of the Bagger-Lambert-Gustavsson theory. The original SO(8) R-symmetry is broken to SO(3) × SO(5), where the former may be interpreted as a diagonal subgroup of the Euclidean M5-brane world-volume symmetry ...
Pruacan is a rare medicinal plant endemic to the Dieng Plateau of Central Java, Indonesia which has properties as an aphrodisiac. Increasing genetic variability ofthis in order support breeding programs and increase productivity active ingredients this important. This study aimed evaluate effect chemical mutagen EMS on growth development vitro culture pruacan lethal dose determination. Embryoge...
Objective(s):Electromagnetic radiations which have lethal effects on the living cells are currently also considered as a disinfective physical agent. Materials and Methods: In this investigation, silver nanoparticles were applied to enhance the lethal action of low powers (100 and 180 W) of 2450 MHz electromagnetic radiation especially against Escherichia coli ATCC 8739. Silver nanoparticles ...
Background: Lung cancer is the most common cause of cancer death worldwide. Despite extensive efforts, an ideal medicine has not been yet found for cancer treatment. Cinnamon contains strong anti-oxidative compounds. This study evaluated and compared the lethal effect of cinnamon extract on the A459 line lung cancer cells with cyclophosphamide. Methods: Cinnamon extract was prepared by so...
In the process of identifying heterotic and Type II BPS string states with extremal dilaton black holes, it has been suggested that solutions with scalar/Maxwell parameters a = √ 3, 1, 1/ √ 3 and 0 correspond to 1−, 2−, 3− and 4-particle bound states at threshold. (For example, the Reissner-Nordstrom black hole is just a superposition of four Kaluza-Klein black holes). Here we show that not onl...
We study the stability of non-Abelian semi-local vortices based on an N = 2 supersymmetric H = SU(Nc)×U(1)/ZNc ∼ U(Nc) gauge theory with an arbitrary number of flavors (Nf > Nc) in the fundamental representation, when certain N = 1 mass terms are present, making the vortex solutions no longer BPS-saturated. Local (ANO-like) vortices are found to be stable against fluctuations in the transverse ...
It is argued that D = 10 type II strings and M-theory in D = 11 have D − 5 branes and 9-branes that are not standard p-branes coupled to anti-symmetric tensors. The global charges in a D-dimensional theory of gravity consist of a momentum P M and a dual D − 5 form charge K M1...MD−5 , which is related to the NUT charge. On dimensional reduction, P gives the electric charge and K the magnetic ch...
The 256 dimensional M2-brane multiplet contains solitons of many different intrinsic spins. Using the broken supersymmetry transformations of the M2-brane, we find supergravity solutions which explicitly display these spins. This amounts to quantizing the fermionic zero modes and computing the back reaction on the metric and gauge potential. These spacetime fields are therefore operator valued ...
A series of new palmatine derivatives with alkyl or alkyl with N-heterocyclic structures were designed and synthesized at C-9-O according to the principle of association. These compounds were characterised by (1)H NMR, (13)C NMR, ESI-MS and elemental analysis, and tested for their antimicrobial activity in vitro to evaluate structure-activity relationships. The results indicated that 9-O-substi...
Recently, the author has constructed a series of four dimensional non-critical string theories with eight supercharges, dual to theories of light electric and magnetic charges, for which exact formulas for the central charge of the space-time supersymmetry algebra as a function of the world-sheet couplings were obtained. The basic idea was to generalize the old matrix model approach, replacing ...
