We show that excited baryons in large Nc QCD form multiplets, within which masses are first split at O(1/Nc). The dominant couplings of resonances to various mesons are highly constrained: The N(1535) decays at leading 1/Nc order exclusively to η-N rather than π-N , and vice versa for the N(1650). This multiplet structure is reproduced by a simple large Nc quark model, well studied in the liter...

An NC 1 circuit for division of binary numbers is presented. By results of Beame, Cook and Hoover this also shows that iterated product and powering are in NC 1 , and by a result of Borodin all three operations are in log-space. This settles an open issue in parallel and space bounded arithmetic complexity.

Objective: the neck circumference (NC) as an index of obesity and upper-body subcutaneous adipose tissue distribution is recently used. This alternative screening tool is reliable, simple, quick and acceptable for assessment of overweight and obesity. the objectives of this study were to examine the correlation between NC measurement and diagnosis of general/visceral obesity and determining the...

In this work we investigated the possibility of substituting diphenylamine (DPA) by natural product 2-methoxy phenol, known as guaiacol (CAS 90-05-1), a stabilizer for nitrocellulose (NC)-based propellants. Stability evaluation, using heat flow calorimetry, revealed lower flows associated with our guaiacol-stabilized propellant samples when compared to those propellants stabilized traditional s...

this experiment was performed to determine the role of vitamin e and coenzyme q10 antioxidants on performance and ascites parameters of broiler chicks in cold stress conditions using a completely randomized design with 5 treatments and 5 replicates in each treatment. treatments were: positive control (pc, normal thermal conditions without antioxidants), negative control (nc, cold stress without...

has at least n+ 1 distinct prime divisors. (b) When a = 3, determine all the positive integers n for which the assertion in (a) is false. 2. ABCD is a square; points U and V are situated on the respective sides BC and CD. Prove that the perimeter of triangle CUV is equal to twice the sidelength of the square if and only if ∠UAV = 45◦. 3. Let f(x) be a convex increasing realvalued function defin...

In this study the effect of crystallite size reduction and microstructure on the electrochemical corrosion behavior of nanocrystalline nickel (NC Ni) were investigated using Tafel polarization and electrochemical impedance spectroscopy (EIS) measurements in 10 wt.% NaOH. NC Ni coatings were produced by direct current electrodeposition using chloride baths in presence and absence of saccharin as...

A subgroup $H$ is said to be $nc$-supplemented in a group $G$ if there exists a subgroup $Kleq G$ such that $HKlhd G$ and $Hcap K$ is contained in $H_{G}$, the core of $H$ in $G$. We characterize the supersolubility of finite groups $G$ with that every maximal subgroup of the Sylow subgroups is $nc$-supplemented in $G$.
