Autor: L. Kovács, F.L. Kézér, F. Ruff, M. Czirok, M. Bakony, V. Jurkovich

Publikováno v: Journal of Dairy Science, Vol 107, Iss 9, Pp 7245-7255 (2024)

ABSTRACT: We studied the changes in the heart rate variability of lame and nonlame dairy cows in response to transrectal examination (TRE) and parlor milking. We hypothesized that lame cows experience greater stress, manifested in heart rate variabil

Single-cell microfluidics in combination with chlorophyll a fluorescence measurements to assess the lifetime of the Chlamydomonas PSBO protein

Autor: E. Széles, S. Kuntam, A. Vidal-Meireles, V. Nagy, K. Nagy, Á. Ábrahám, L. Kovács, S.Z. Tóth

Publikováno v: Photosynthetica, Vol 61, Iss SPECIAL ISSUE 2023-2, Pp 417-424 (2023)

PSBO is an essential subunit of the oxygen-evolving complex and we recently demonstrated that its lifetime depends on environmental conditions in Chlamydomonas reinhardtii. To assess PSBO lifetime with a high time resolution, we employed (1) a microf

REAL-TIME FOREGROUND SEGMENTATION FOR SURVEILLANCE APPLICATIONS IN NRCS LIDAR SEQUENCES

Autor: L. Kovács, M. Kégl, C. Benedek

Publikováno v: The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Vol XLIII-B1-2022, Pp 45-51 (2022)

In this paper, we propose a point-level foreground-background separation technique for the segmentation of measurement sequences of a Non-repetitive Circular Scanning (NRCS) Lidar sensor, which is used as a 3D surveillance camera mounted in a fixed p

Single-dose meloxicam treatment improves standing ability of low-vitality dairy calves

Autor: L. Kovács, F.L. Kézér, F. Ruff, M. Samardzija, O. Szenci

Publikováno v: Journal of Dairy Science, Vol 105, Iss 2, Pp 1618-1624 (2022)

ABSTRACT: A promising strategy to improve newborn calf survival could be the administration of nonsteroidal antiinflammatory drugs (NSAID) especially in cases of low vitality calves born from difficult calvings. The objective of this clinical trial w

Step behaviour and autonomic nervous system activity in multiparous dairy cows during milking in a herringbone milking system

Autor: F.L. Kézér, L. Kovács, J. Tőzsér

Publikováno v: Animal, Vol 9, Iss 8, Pp 1393-1396 (2015)

Behavioural and cardiac responses of multiparous dairy cows (n=24) during milking in a 2×4 stall herringbone milking system were evaluated in this study. Heart rate (HR), parasympathetic tone index (high frequency component, HF) of heart rate variab

Welfare implication of measuring heart rate and heart rate variability in dairy cattle: literature review and conclusions for future research

Autor: L. Kovács, V. Jurkovich, M. Bakony, O. Szenci, P. Póti, J. Tőzsér

Publikováno v: Animal, Vol 8, Iss 2, Pp 316-330 (2014)

Heart rate (HR) measurements have been used to determine stress in livestock species since the beginning of the 1970s. However, according to the latest studies in veterinary and behaviour–physiological sciences, heart rate variability (HRV) proved

Fruits are essential part of the human diet: they provide vitamins, minerals, antioxidants to the mankind. Physiologically they can be divided into two groups-climacteric and nonclimacteric - depending if they display any respiratory peak and dramati

Publikováno v: International Journal of Horticultural Science, Vol 8, Iss 3-4 (2002)

Drop tests were performed with different tomato cultivars. „Rupture" and „no rupture" conditions were determined as results. The proportion of „rupture" was shown versus the drop height and the relationships were described by a logistic functio

Solubility and permeability are key parameters for establishing in vitro-in vivo correlation for poorly water-soluble active pharmaceutical ingredients (APIs). Recent studies demonstrate that not only solubility, but also effective permeability of th
