Pseudorapidity distributions of charged particles emitted in $Au+Au$, $Cu+Cu$, $d+Au$, and $p+p$ collisions over a wide energy range have been measured using the PHOBOS detector at RHIC. The centrality dependence both particle multiplicity midrapidity were measured. with $|\eta|<5.4$, which account for between 95% 99% total charged-particle emission associated collision participants, are presented different centralities. Both density, $dN_{ch}/d\eta$, multiplicity, $N_{ch}$, found to...
We present measurements of the pseudorapidity distribution primary charged particles produced in $\mathrm{A}\mathrm{u}+\mathrm{A}\mathrm{u}$ collisions at three energies, $\sqrt{{s}_{NN}}=19.6$, 130, and 200 GeV, for a range collision centralities. The narrows more central excess are high peripheral collisions. For given centrality, however, distributions found to scale with energy according ``limiting fragmentation'' hypothesis. universal fragmentation region described by this scaling grows...
We present the first measurement of pseudorapidity densities primary charged particles near midrapidity in Au+Au collisions at sqrt[s(NN)] = 56 and 130 GeV. For most central collisions, we find charged-particle density to be dN/deta|(|eta|<1) 408+/-12(stat)+/-30(syst) GeV 555+/-12(stat)+/-35(syst) GeV, values that are higher than any previously observed nuclear collisions. Compared proton-antiproton our data show an increase per participant by more 40% energy.
"I" did it: An iodine(III)-mediated bromocarbocyclization was elaborated as an efficient tool for the synthesis of oxoindoles. This method is applicable to a variety structurally different substrates, also with chemically sensitive groups, and gives access heterocycles in regio- stereoselective fashion (see scheme). The indole-2-ones obtained can be converted easily into complex target compounds, such alkaloid physostigmine.
The charged-particle pseudorapidity density dNch/dη has been measured for Au+Au collisions at √sNN=130GeV RHIC, using the PHOBOS apparatus. total number of charged particles produced 3% most-central |η|≤5.4 is found to be 4200±470. evolution with centrality discussed, and compared model calculations data from proton-induced collisions. show an enhancement in production midrapidity, while fragmentation regions, results are consistent expectations pp pA scattering.Received 6 June...
The PHOBOS experiment has measured the charged particle multiplicity at mid-rapidity in Au+Au collisions sqrt(s_NN) = 200 GeV as a function of collision centrality. Results on dN/deta(eta<1) divided by number participating nucleon pairs, , are presented . As was found from similar data 130 GeV, can be equally well described parton saturation models and two-component fits which include contributions that scale Npart binary collisions, Ncoll. We compare two energies means ratio R(200/130)...

These results call into question common assumption...
We present the first measurement of pseudorapidity density primary charged particles in Au+Au collisions at root square[s(NN)] = 200 GeV. For 6% most central collisions, we obtain dN(ch)/d(eta)/(/eta/<1) 650+/-35(syst). Compared to 130 GeV, highest energy studied previously, an increase by a factor 1.14+/-0.05 90% confidence level, is found. The dependence discussed comparison with data from proton-induced and theoretical predictions.

The single-mirror small-size telescope (SST-1M) is one of the three proposed designs for telescopes (SSTs) Cherenkov Telescope Array (CTA) project. SST-1M will be equipped with a 4 m-diameter segmented reflector dish and an innovative fully digital camera based on silicon photo-multipliers. Since SST sub-array consist up to 70 telescopes, challenge not only build excellent performance, but also design them so that their components can commissioned, assembled tested by industry. In this paper...

Abstract In recent years, spirocyclic compounds have attracted a significant interest in medicinal chemistry due to their considerable biological activities. The general and widely used concept for compound synthesis is related with dearomatization of starting material. However, most the libraries prepared using this comprise structure similarity. Therefore, preparation structurally distinct comprising varied functionality requires different approaches that includes non‐dearomative pathways....
