A commonly used approach in long-run event-studies is the calendar time portfolio (CTP) approach developed by Jaffe (1974) and Mandelker (1974) and advocated by Fama (1998). For each calendar month we compute the return of an equally-weighted portfolio of companies that unionized in the last T months, where T is either 18 or 24 in our study. The return of this “unionization portfolio” is denote...

Forest soils in Northern Europe are generally trafficked by forest machinery on several occasions during a rotation. This may create ruts (wheel tracks), which could increase sediment transport to nearby surface water, reduce recreational value, and affect tree growth. It is therefore important soil disturbance off-road transportation. In this study, rut depth was measured following forwarder t...

Surface hot-in place recycling of asphalt mixtures has been conducted on Finnish roads for several years. The procedure is performed either in full-lane('remix') or shorter widths ('rut-remix'). In a 2020-2021 project, different mixture types were subjected to both kinds recycling; reference mixtures, and modified with aramid fibres, FEP elastomer pellets, polymer, Storelastic rubber additive, ...

Traditionally, glycyrrhizic acid has been used to form polydentate complexes. For the first time in presented paper, complexation of Plant’s Flavonoids (Quercetin (Qu) and its glycoside - Rutin (Rut)) with novel Russian antiviral drug Camphecene (Camph) was investigated. The complexes obtained at different molar ratios were studied using UV/Vis spectroscopy. Formation host: guest registered: Qu...

Several mutations in Drosophila impair learning and the cAMP cascade. We report here that the fine morphology of an identified mechanosensory neuron is abnormal in two of these mutants, dunce (dnc) and rutabaga (rut). The neuron innervating the antero-notopleural bristle was filled with horseradish peroxidase and studied at the light- and electron-microscopy level. In the mutants dnc and rut, t...

background and aims: helicobacter pylori (h. pylori) is the microorganism that infects nearly half of word's population. there are several invasive and non-invasive methods for diagnosis of infection. the main objective of this study was to evaluate antigen of h. pylori in feces with h. pylori stool antigen (hpsa) test and comparison with rapid urease test (rut) in the patients suspected t...

Helicobacter pylori is main causative agent of acute gastritis and peptic ulcer disease. In certain population, this infection leads to gastric cancers viz., adenocarcinoma, mucosal-associated lymphoid tissue (MALT) lymphoma. The objective study was comparatively evaluate invasive (RUT) non-invasive (IgM IgG ELISA) methods for detection H. among patients visiting a tertiary care hospital. A tot...
