A general approach to weighted L p rellich type inequalities related to greiner operator
No full textIn this paper we exhibit some sufficient conditions that imply general weighted L p Rellich type inequality related to Greiner operator without assuming a priori symmetric hypotheses on the weights. More precisely, we prove that given two nonnegative functions a and b, if there exists a positive supersolution ? of the Greiner operator ? ? such that ? ? (a|? ? ?| p-2 ? ? ?)?b? p-1 almost everywhere in R 2n+1 ; then a and b satisfy a weighted L p Rellich type inequality. Here, p > 1 and ? ? = ? n j=1 (x 2 j +y 2 j ) is the sub-elliptic operator generated by the Greiner vector fields x j {equation presented} where (z,l)=(x,y,l)? R 2n+1 =R n ×R n ×R,|Z|={equation presented} and k ? 1. The method we use is quite practical and constructive to obtain both known and new weighted Rellich type inequalities. On the other hand, we also establish a sharp weighted L p Rellich type inequality that connects first to second order derivatives and several improved versions of two-weight L p Rellich type inequalities associated to the Greiner operator ? ? on smooth bounded domains ? in R 2n+1 . © 2019 American Institute of Mathematical Sciences.

Palatability as indicated by preference by model herbivore
No full textV diplomskem delu smo raziskovali morfološko-funkcionalno potezo (MFP), in sicer okusnost listov na primeru modelnega herbivora. Naša raziskava je bila osnovana na 600 rastlinskih vzorcih, ki so zajemali kulturne in travniške rastline. Kot modelni herbivor smo izbrali rdečega lazarja (Arion rufus L.). Prvotno smo primerjali testne vzorce vseh rastlinskih vrst z njihovimi kontrolami. Ugotovili smo, da so herbivori najmanj objedali liste rastlinskih vrst Rubis idaeus L., Melissa officinalis L. in Cucumis sativus L., najpogosteje pa so se prehranjevali z listi vrst Taraxacum officinale L. in Erigeron annuus L.. V skladu z našimi predvidevanji so herbivori najmanj objedli liste rastlin s prisotnostjo sekundarnih sprememb celične stene, epidermalnimi tvorbami ter nizko hranilno vrednostjo. V nasprotju z našimi pričakovanji pa prisotnost sekundarnih metabolitov v listih ni imela vpliva na sam izbor herbivora. V naši raziskavi smo tudi ugotovili, da se modelni herbivor raje prehranjuje z izbranimi travniškimi rastlinskimi vrstami kot pa s kulturnimi.In graduation thesis, we have researched leaf palatability as indicated by preference by model herbivore, which is one of the morphological – functional traits (MFT). Our research was based on 600 plant samples, which included cultivated and grassland plants. We incorporated Arion rufus L. as a model herbivore. First, we compared test samples with their controls for each of the plant species. We came to the conclusion that herbivores were avoiding plants Rubis Idaeus L., Melissa Officinalis L. in Cucumis sativus L. and were prefering Taraxacum officinale L. in Erigeron Annuus L.. In accordance with our expectations, leaf preference was most influenced by secondary cell wall changes, epidermal outgrowths and nutritional value. Contrary to our predictions, secondary metabolites did not have a dominant influence on leaf palatability. We concluded that herbivores prefer grassland plants over cultivated plants

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Detailed optical and near-infrared polarimetry, spectroscopy and broad-band photometry of the afterglow of GRB 091018 : polarization evolution
No full textFollow-up observations of large numbers of gamma-ray burst (GRB) afterglows, facilitated by the Swift satellite, have produced a large sample of spectral energy distributions and light curves, from which their basic micro- and macro-physical parameters can in principle be derived. However, a number of phenomena have been observed that defy explanation by simple versions of the standard fireball model, leading to a variety of new models. Polarimetry can be a major independent diagnostic of afterglow physics, probing the magnetic field properties and internal structure of the GRB jets. In this paper we present the first high-quality multi-night polarimetric light curve of a Swift GRB afterglow, aimed at providing a well-calibrated data set of a typical afterglow to serve as a benchmark system for modelling afterglow polarization behaviour. In particular, our data set of the afterglow of GRB 091018 (at redshift z = 0.971) comprises optical linear polarimetry (R band, 0.13-2.3d after burst); circular polarimetry (R band) and near-infrared linear polarimetry (Ks band). We add to that high-quality optical and near-infrared broad-band light curves and spectral energy distributions as well as afterglow spectroscopy. The linear polarization varies between 0 and 3per cent, with both long and short time-scale variability visible. We find an achromatic break in the afterglow light curve, which corresponds to features in the polarimetric curve. We find that the data can be reproduced by jet break models only if an additional polarized component of unknown nature is present in the polarimetric curve. We probe the ordered magnetic field component in the afterglow through our deep circular polarimetry, finding P circ < 0.15per cent (2σ), the deepest limit yet for a GRB afterglow, suggesting ordered fields are weak, if at all present. Our simultaneous R- and Ks-band polarimetry shows that dust-induced polarization in the host galaxy is likely negligible
