Adubação do feijoeiro (Phaseolus vulgaris L.) em um cambisol do estado de Sergipe

The effects of NPK on the yield of bean was studied by means of a 3³ factorial experiment In an incomplete block design according to Yates confounded W model. The experiment was conducted in the same site for two subsequent years. Rates of nutrient utilized were as follows: nitrogen (0, 20 and 40 kg/ha of N) , phosphorus (0, 50 and 100 kg/ha of P(2)0(5)) and potassium (0, 20 and 40 kg/ha of K(2)0) applied as urea, triple superphosphate and potassium chloride, respectively. All plots received an uniform application of 60 kg/ha of S as calcium sulfate, 4 kg/ha of Zn as zinc sulfate, 4 kg/ /ha of Cu as copper sulfate, 1 kg/ha of B as borax and 0,2 kg/ha of Mo as sodium molibdate. A number of extratreatments was planted with the main field trial to study the effect of sulfur and micronutrients. The same rates indicated above were used. Treatments were as follows: check, complete minus S, complete minus micro and complete (NPK S micro). These treatments were analysed as a randomized block experiment. The results obtained led to the following conclusions: a) yield of common beans was significantly affected by the application of phosphorus in the two years the field experiment was planted; b) no significant effects on the yield of beans were detected for nitrogen, potassium, sulfur and the composite mixture of micronutrients.Os efeitos de NPK na produção do feijoeiro foram estudados através de um experimento fatorial 3³, disposto em blocos incompletos segundo o modelo de confundimento W de Yates. Este experimento foi conduzido dois anos no mesmo local, sendo as seguintes as doses dos nutrientes: nitrogênio (0, 20 e 40 kg/ha de N),fósforo (0, 50 e 100 kg/ha de P(2)0(5)) e potássio (0, 20 e 40 kg/ha de k(2)0) os quais tiveram como fontes uréia, superfosfato triplo e cloreto de potássio, respectivamente. Todas as parcelas receberam uma adubação uniforme com enxofre e micronutrientes, nas seguintes doses e fontes: 60 kg/ha de S como sulfato de cálcio, 4 kg/ha de Zn como sulfato de zinco, 4 kg/ha de cobre como sulfato de cobre, 1 kg/ha de B como borax como borax e 0,2 kg/ha de Mo como molibdato de sódio. Os resultados obtidos permitiram concluir que: a) o fósforo causou aumentos altamente significativos na produção do feijoeiro, nos dois anos de condução do ensaio; b) não foram observados efeitos significativos do nitrogênio, potássio, enxofre e da mistura de micronutrientes na produção do feijoeiro

NEOTROPICAL XENARTHRANS: a data set of occurrence of xenarthran species in the Neotropics

Xenarthrans – anteaters, sloths, and armadillos – have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts with 24 domestic dogs, these species have been threatened locally, regionally, or even across their full distribution ranges. The Neotropics harbor 21 species of armadillos, ten anteaters, and six sloths. Our dataset includes the families Chlamyphoridae (13), Dasypodidae (7), Myrmecophagidae (3), Bradypodidae (4), and Megalonychidae (2). We have no occurrence data on Dasypus pilosus (Dasypodidae). Regarding Cyclopedidae, until recently, only one species was recognized, but new genetic studies have revealed that the group is represented by seven species. In this data-paper, we compiled a total of 42,528 records of 31 species, represented by occurrence and quantitative data, totaling 24,847 unique georeferenced records. The geographic range is from the south of the USA, Mexico, and Caribbean countries at the northern portion of the Neotropics, to its austral distribution in Argentina, Paraguay, Chile, and Uruguay. Regarding anteaters, Myrmecophaga tridactyla has the most records (n=5,941), and Cyclopes sp. has the fewest (n=240). The armadillo species with the most data is Dasypus novemcinctus (n=11,588), and the least recorded for Calyptophractus retusus (n=33). With regards to sloth species, Bradypus variegatus has the most records (n=962), and Bradypus pygmaeus has the fewest (n=12). Our main objective with Neotropical Xenarthrans is to make occurrence and quantitative data available to facilitate more ecological research, particularly if we integrate the xenarthran data with other datasets of Neotropical Series which will become available very soon (i.e. Neotropical Carnivores, Neotropical Invasive Mammals, and Neotropical Hunters and Dogs). Therefore, studies on trophic cascades, hunting pressure, habitat loss, fragmentation effects, species invasion, and climate change effects will be possible with the Neotropical Xenarthrans dataset

Study of the lineshape of the chi(c1) (3872) state

A study of the lineshape of the chi(c1) (3872) state is made using a data sample corresponding to an integrated luminosity of 3 fb(-1) collected in pp collisions at center-of-mass energies of 7 and 8 TeV with the LHCb detector. Candidate chi(c1)(3872) and psi(2S) mesons from b-hadron decays are selected in the J/psi pi(+)pi(-) decay mode. Describing the lineshape with a Breit-Wigner function, the mass splitting between the chi(c1 )(3872) and psi(2S) states, Delta m, and the width of the chi(c1 )(3872) state, Gamma(Bw), are determined to be (Delta m=185.598 +/- 0.067 +/- 0.068 Mev,)(Gamma BW=1.39 +/- 0.24 +/- 0.10 Mev,) where the first uncertainty is statistical and the second systematic. Using a Flatte-inspired model, the mode and full width at half maximum of the lineshape are determined to be (mode=3871.69+0.00+0.05 MeV.)(FWHM=0.22-0.04+0.13+0.07+0.11-0.06-0.13 MeV, ) An investigation of the analytic structure of the Flatte amplitude reveals a pole structure, which is compatible with a quasibound D-0(D) over bar*(0) state but a quasivirtual state is still allowed at the level of 2 standard deviations

Measurement of the CKM angle γγ in B±→DK±B^\pm\to D K^\pm and B±→Dπ±B^\pm \to D π^\pm decays with D→KS0h+h−D \to K_\mathrm S^0 h^+ h^-

A measurement of $CP$-violating observables is performed using the decays $B^\pm\to D K^\pm$ and $B^\pm\to D \pi^\pm$, where the $D$ meson is reconstructed in one of the self-conjugate three-body final states $K_{\mathrm S}\pi^+\pi^-$ and $K_{\mathrm S}K^+K^-$ (commonly denoted $K_{\mathrm S} h^+h^-$). The decays are analysed in bins of the $D$-decay phase space, leading to a measurement that is independent of the modelling of the $D$-decay amplitude. The observables are interpreted in terms of the CKM angle $\gamma$. Using a data sample corresponding to an integrated luminosity of $9\,\text{fb}^{-1}$ collected in proton-proton collisions at centre-of-mass energies of $7$, $8$, and $13\,\text{TeV}$ with the LHCb experiment, $\gamma$ is measured to be $\left(68.7^{+5.2}_{-5.1}\right)^\circ$. The hadronic parameters $r_B^{DK}$, $r_B^{D\pi}$, $\delta_B^{DK}$, and $\delta_B^{D\pi}$, which are the ratios and strong-phase differences of the suppressed and favoured $B^\pm$ decays, are also reported
