The prime graph $Gamma(G)$ of a group $G$ is a graph with vertex set $pi(G)$, the set of primes dividing the order of $G$, and two distinct vertices $p$ and $q$ are adjacent by an edge written $psim q$ if there is an element in $G$ of order $pq$. Let $pi(G)={p_{1},p_{2},...,p_{k}}$. For $pinpi(G)$, set $deg(p):=|{q inpi(G)| psim q}|$, which is called the degree of $p$. We also set $D(G):...

We have previously provided evidence that the uptake of DNA into cells is cell cycle specific following transfection. We show here that, immediately after transfection, successfully transfected cells are greatly enriched for cells in early G1 or G0 phase and that, upon removal of the DNA precipitates, cells progress through G1 and enter S phase in a synchronous fashion. We also demonstrate that...

To engineer T(h) determinants (THd) to prime help for humoral or cytotoxic T cell responses, we modified ovalbumin [OVA(323-337)] and myoglobin [MYO(106-118)] eliciting T(h)1 and T(h)0 cytokine profiles respectively. Residues along the sequence of both THd were replaced with amino acids representative of different families. Replacements at positions P-1 and P5 pointing to the TCR in both THd af...

Using an almost complete relativistic method based on the Bethe-Salpeter equation, we study mixing angle $\theta$, mass splitting $\bigtriangleup M$, strong decay widths $\Gamma(D^{({\prime})}_1)$ and weak production rates $Br(B\to D^{({\prime})}_1\ell\nu_{\ell})$ of $D_1(2420)$ $D_1^{\prime}(2430)$. We find there is cancellation between $^1P_1$ $^3P_1$ partial waves in $D_1^{\prime}(2430)$ wit...

Let M be a 2-torsion free prime Γ-ring and X a nonzero faithful and prime ΓM -module. Then the existence of a nonzero Jordan left derivation d : M → X satisfying some appropriate conditions implies M is commutative. M is also commutative in the case that d : M → M is a derivation along with some suitable assumptions. AMS (MOS) Subject Classification Codes: 03E72, 54A40, 54B15

The recently developed refractory multi-principle element alloy (MPEA), AlMo$_{0.5}$NbTa$_{0.5}$TiZr, shows an interesting microstructure with cuboidal precipitates of a disordered phase (${\beta}$, bcc) coherently embedded in ordered (${\beta}'$, B2) matrix, unlike the conventional Ni-based superalloys where (${\gamma}'$, L12) is precipitate and (${\gamma}$, fcc) matrix phase. It becomes criti...

One of the obstacles in analyzing frozen urine samples is the formation of uncharacterized precipitates. Frequently, these precipitates are discarded before analysis. Some laboratory data may be erroneous if these precipitates contain important compounds. In the present study, we examined urinary sediments precipitated after overnight storage at -20 degrees C. Although cells and debris were rem...
