The three pentaquark candidates Θ(1530), Ξ(1862) and Θc(3100) have been studied in ep collisions at a centre-of-mass energy √ s = 300 − 318 GeV using the full luminosity of the HERA-I data. Searches for narrow baryonic states in the decay channels K S p, Kp, Ξ−π±, Ξ̄+π± and D∗±p∓ are reported. The results support the existence of a narrow resonance decaying into K S p and K S p̄, consistent with ...

An in situ acetate injection was used to determine the influence of labile dissolved organic carbon (DOC) availability on microbial respiration in the hyporheic zone of a headwater stream. We added bromide as a conservative tracer and acetate as an organic substrate to the hyporheic zone of Rio Calaveras, New Mexico, via an injection well. Tracer was observed in four of eight capture wells. Thr...

Glucagon-like peptide 1 (GLP-1) is a potent glucose-lowering agent of potential interest for the treatment of type 2 diabetes. To evaluate actions of NN2211, a long-acting GLP-1 derivative, we examined 11 patients with type 2 diabetes, age 59 +/- 7 years (mean +/- SD), BMI 28.9 +/- 3.0 kg/m(2), HbA(1c) 6.5 +/- 0.6%, in a double-blind, placebo-controlled, crossover design. A single injection (10...

We report on searches in deep inelastic ep scattering for narrow baryonic states decaying into Ξ − π − , Ξ − π + , K 0 S p and their charge conjugates, at centre-of-mass energies of 300 and 318 GeV. No signal for a new narrow baryonic state is observed in the mass ranges 1600-2100 MeV (Ξπ) and from threshold up to 1700 MeV (K 0 S p). The standard baryon Ξ(1530) 0 is observed in the decay mode Ξ...

We present the results of the experimental study and comparison of Yb-free, Erdoped, all-fiber, alignment free, single frequency (SF) fiber amplifiers operating under 980-, 1470and 1530-nm pumping for the coreand clad-pumping architectures. In the single-mode core-pumped configuration Er-doped fiber amplifiers demonstrated 52% and 60% pump to output efficiencies for 980 and 1480 nm pump wavelen...

Johannes Gregor Macer Szepsius (ca. 1530 – after 1579) wrote an epigram in praise of his friend Anton Schneeberger (1530–1581) and a celebratory poem on genealogy, both appearing Schneeberger's most famous book, De bona militum valetudine conservanda [On the Good Health Soldiers] 1564. However, praising ancestry appears only printed version book; surviving manuscript copy work Palace Library An...

Motivated by the possible observation of the Θ+(1530), we study the quark structure of pentaquark states in quenched lattice QCD. The complete set of 19 local sources that have the proper symmetry for positive or negative parity isoscalar pentaquarks is constructed, as well as a nonlocal source composed of two displaced “good” diquarks. Quantitative structure information is determined from diag...

The Lurín River is one of the main sources water for city Lima. However, discharge domestic wastewater, presence dumps, and long periods drought cause deterioration resource. In this study, DO, BOD5, E. coli, T, EC, TSS, U, h were monitored at 13 monitoring points spread over 20 km river influence. This information was used to calibrate parameters Kdbo, Kaire, Kdos, Kdec in Iber two-dimensional...
