Special issue in honour of Prof. Reto J. Strasser - JIP-test as a tool for early diagnostics of plant growth and flowering upon selected light recipe

open access: yesPhotosynthetica, 2020
Light is a major factor controlling plant growth and development. To assess the impact of the applied light conditions, we aimed to sort out a tool for early diagnostics of the plant physiological state.

Response analysis of residual soil slope considering crack development under drying−wetting cycles

open access: yesRock and Soil Mechanics, 2021
In order to study the response of granite residual soil slope with cracks under different number of drying-wetting cycles (D-W cycles), model test was carried out and the crack width expansion index was quantified by investigating the crack images. Based

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Characterization of a spherical heat source for measuring thermal conductivity and water content of ethanol and water mixtures

open access: yesInternational Journal of Metrology and Quality Engineering, 2017
The study and the development of measuring methods of thermal conductivity are essential in several engineering applications, since as a consequence of the current justified demands on saving and rational use of thermal energy, the heat transfer with the

Nutrient/TOR signaling controls adipose mitochondrial transcription factor A (TFAM) to regulate organismal growth in Drosophila

open access: yesFEBS Letters, EarlyView.
Animals must match their growth rate to available nutrients. We show that in Drosophila larvae, the nutrient‐sensing TOR kinase controls growth by regulating levels of TFAM, a key regulator of mitochondrial function, in the adipose tissue. When nutrients are abundant, high TOR activity suppresses TFAM, lowering mitochondrial bioenergetic activity and ...

Soil water movement modelling in hapllicc luvisols (HMm) and albi hapllic luvisols (HMl) under Slovak climatic conditions

open access: yesJournal of Environmental Engineering and Landscape Management, 2007
The aim of the research paper is simulation by the Global Model on the basis of investigation of Slovak Agricultural University (SAU) on two localities (Kolínany and Malanta). The soil moisture was measured by a time domain transmissometry instrument and

The microbiome in human skin aging

open access: yesFEBS Letters, EarlyView.
Age‐related skin changes encompass the well‐known visible phenotypic alterations, together with microbiome dysbiosis and a series of molecular aging hallmarks. These hallmarks characterize not only a fully stablished aged phenotype but also the skin aging process itself.

Funções de pedotransferência para estimativa da retenção de água em alguns solos do Rio Grande do Sul Pedotransfer functions to estimate the water retention in some soils of Rio Grande do Sul state, Brazil

open access: yesCiência Rural, 2010
As propriedades hidráulicas do solo são determinações consideradas caras e de difícil obtenção. O uso de funções de pedotransferência (FPTs) consiste em uma alternativa para a obtenção dessas informações de forma mais fácil e com menor custo.
