Partial wave analysis of ψ(2S)→ppˉη
2013
Using a sample of 1.06 x 10(8) psi(2) events collected with the BESIII detector at BEPCII, the decay psi(2S) -> p (p) over bar eta is studied. A partial wave analysis determines that the intermediate state N(1535) with a mass of 1524 +/- 5(-4)(+10) MeV/c(2) and a width of 130(-24-10)(+27+57) MeV/c(2) is dominant in the decay; the product branching fraction is determined to be B(psi(2S) -> N(1535)(p) over bar x B(N(1535) -> p eta + c.c. = 5.2 +/- 0.3(-1.2)(+3.2)) x 10(-5). Furthermore, the branching fraction of psi(2S) -> p (p) over bar eta is measured to be (6.4 +/- 0.2 +/- 0.6) x 10(-5). Here, the first error is statistical and the second is systematic.
An improved limit for Γee of X(3872) and Γee measurement of ψ(3686)
2015
Using the data sets taken at center-of-mass energies above 4 GeV by the BESIII detector at the BEPCII storage ring, we search for the reaction e+eââγISRX(3872)âγISRÏ+ÏâJ/Ï via the Initial State Radiation technique. The production of a resonance with quantum numbers JPC=1++ such as the X(3872) via single photon e+eâ annihilation is forbidden, but is allowed by a next-to-leading order box diagram. We do not observe a significant signal of X(3872) , and therefore give an upper limit for the electronic width times the branching fraction ÎeeX(3872)B(X(3872)âÏ+ÏâJ/Ï)<0.13 eV at the 90% confidence level. This measurement improves upon existing limits by a factor of 46. U…

Control de plagas y desarrollo institucional en la estación de Patología Vegetal de Burjassot (Valencia)
2006
The Estación de Patología Vegetal de Burjassot (Valencia), created in 1924, carried out important activities related to the control of pests, in varied fronts as original research, adaptation of techniques, and popularization. The biological control was highly practiced, and it was centered on orange pests. The chemical control of pests was also developed in this center.
Brief an Garlieb H. Merkel
1799
Ms. 930a, Nr. 8, Bl. 22r-23v Böttiger, Karl August. Brief an Garlieb H. Merkel, Weimar, d[en] 13. November 1797 Autora rokraksts / Autograph, vācu, angļu un latīņu val. / Deutsch, Englisch und Latein [4] lpp. / S. Attēlu numuri / Bildnummern: 930a-008-1 – 930a-008-4 Der Verfasser nennt in diesem inhaltsreichen Brief zahlreiche Namen und hält nicht nur die Verbindung mit Merkel, die aus dessen erstem Aufenthalt in Weimar resultierte, aufrecht, sondern gibt ihm weitere Hinweise und Empfehlung für seinen weiteren Aufenthalt in Dänemark. So rät er zur Übersetzung dreier Romane aus dem Englischen, darunter Jane Wests „A gossip's story“ (London 1796). Ferner bittet der Verfasser Merkel um Gefälli…
