LHC data challenges the contemporary parton-to-hadron fragmentation functions

We discuss the inclusive high-pT charged-particle production in proton-proton collisions at the LHC. The experimental data are compared to the NLO perturbative QCD calculations employing various sets of parton-to-hadron fragmentation functions. Most of the theoretical predictions are found to disastrously overpredict the measured cross sections, even if the scale variations and PDF errors are accounted for. The problem appears to arise from the presently too hard gluon-to-hadron fragmentation functions.Comment: Transcription of the talk given in DIS2014 conferenc

Modeling the Impact Parameter Dependence of the nPDFs With EKS98 and EPS09 Global Fits

So far the nuclear PDFs (nPDFs) in the global DGLAP fits have been taken to be spatially independent. In this work, using the $A$-dependence of the globally fitted sets EPS09 and EKS98, we have determined the spatial dependence of the nPDFs in terms of powers of the nuclear thickness functions. New spatially dependent nPDF sets EPS09s (NLO, LO, error sets) and EKS98s (LO) are released. As an application, we consider the nuclear modification factor $R_{dAu}^{\pi^0}$ at midrapidity for neutral pion production in deuteron-gold collisions at RHIC in NLO. Comparison with the PHENIX data in different centrality classes is also shown. In addition, predictions for the corresponding nuclear modification factor $R_{pPb}^{\pi^0}$ in proton-lead collisions at the LHC are discussed.Comment: 4 pages, 4 figures, Talk given at Hard Probes 2012, 27 May - 1 June, 2012, Cagliari (Sardinia, Italy).

EPS09s and EKS98s: Impact parameter dependent nPDF sets

In our recent study we have determined two new spatially dependent nuclear PDF (nPDF) sets, EPS09s and EKS98s. With these, the hard-process cross-sections can be calculated in different centrality classes consistently with the globally analyzed nPDFs for the first time. The sets were determined by exploiting the $A$-systematics of the globally fitted nPDF sets, EPS09 and EKS98. For the spatial dependence of the nPDFs we used a power series ansatz in the nuclear thickness function $T_A$. In this flash talk we introduce the framework, and present our NLO EPS09s-based predictions for the nuclear modification factor in four centrality classes for inclusive neutral pion production in p+Pb collisions at the LHC and for inclusive prompt photon production in d+Au collisions at RHIC at midrapidity.Comment: 4 pages, 4 figures, Contribution to the proceedings of the Quark Matter 2012, Washington D.C., August 12-18, 201

Meat and bone meal as fertilizer for oats - From slaughter house waste to fertilizer

EU permitted in 2006 the use of meat bone meal(MBM) as fertilizer. MTT Agrifood Research Finland's Kannus conducted a field experiment from 2000 to 2003 with a supplement experiment in 2004. The fertilization effect was 24 % higher after MBM than after chemical fertilizers

Drought spells and their impact on the growth of young plantations established with the containerized planting stock

In 2013-2016, the growth and post-planting losses were monitored of bare-rooted and containerized planting stock of European beech, Norway spruce and Douglas fir together with the course of weather in seven regions of the Czech Republic, most endangered by drought. Precipitation deficits occurred especially in the spring period of 2015 and in the summer period of 2016, significant drought spells being recorded also in the summer periods of years 2013 and 2015. If there is a normal weather after planting, the containerized planting stock exhibits better growth. If the planting is followed by severe spells of drought, both the bare-rooted and the containerized planting stock dies, the containerized planting stock more so. The containerized planting stock responds worse to repeated drought spells. Drought spells are at all times better endured by the containerized planting stock with the large root balls, root ball coverage and strong root collar. Coverage of clear-cut areas is significantly affected by the success of regeneration, which depends on the used type of planting stock, as well as by the spells of drought. Good growth in the first year after planting does not guarantee the success of regeneration, particularly if the containerized planting stock is concerned.O

Beam-Like rods do not Provide Additional Improvement to Thoracic Kyphosis Restoration when Compared to Sagittal Reinforced rods in Adolescents Undergoing Spinal Fusion with Pedicle Screw Instrumentation for Idiopathic Scoliosis

Publisher Copyright: © 2022 The AuthorsObjective: Operative treatment of adolescent idiopathic scoliosis (AIS) with posterior spinal fusion aims for three-dimensional correction of coronal curve and thoracic kyphosis. Our aim was to compare two different designs of asymmetrical rods in adolescents who underwent a posterior spinal fusion with pedicle screw instrumentation for AIS with an emphasis on thoracic kyphosis restoration. Methods: This study was made with 76 consecutive adolescents (mean age 15.6 years, SD 2.0). Thirty-nine patients were operated with sagittal reinforced rods and 37 patients were operated with beam-like rods. The clinical and radiological results were assessed preoperatively, postoperatively, and during the follow-up visits at the outpatient clinic 6 months and 2 years after the surgery. Results: At the last follow-up, the mean (SD) major thoracic curves were 13° (6.2°) and 13° (6.0°) (P = 0.717). Correction percentages were 75% in the sagittal reinforced group and 73% in the beam-like rod group (P = 0.517). The mean (SD) thoracic kyphosis was 24° (11°) and 22° (7.8°) at the two year follow-up in the sagittal reinforced rod group and beamlike rod group (P = 0.517). There was a slight negative correlation between the major curve correction and thoracic kyphosis change in both groups, although this was not statistically significant (R = −0.19, P = 0.094 in the sagittal reinforced rod group, R=−0.16, P = 0.180 in the beam like rod group). Conclusions: There are no significant differences in the coronal or sagittal deformity restoration in adolescent patients who underwent a posterior spinal fusion with sagittal reinforced rods and beam-like rods for adolescent idiopathic scoliosis.Peer reviewe
