Measures to achieve a stable farming system in sustainable agriculture – a short review

open access: yesAnnales Universitatis Paedagogicae Cracoviensis Studia Naturae, 2019
Zrównoważony system rolny jest najlepszym sposobem na zaspokojenie potrzeb dzisiejszych i przyszłych pokoleń. W systemie tym wielkość plonu wzrasta wraz z zastosowaniem upraw międzyrzędowych, poprzez wyższy współczynnik wzrostu roślin, redukcję nasion ...

Photosynthetic characteristics and chlorophyll a fluorescence induction parameters in elite clone (GS1) of Pinus sylvestris var. mongolica

open access: yesPhotosynthetica, 2020
We selected the elite clone of Pinus sylvestris var. mongolica 'GS1' from 365 clones in a primary seed orchard in Liaoning Province, China. To understand the photosynthesis characteristics and mechanisms, 40-year-old 'GS1' trees were compared with a ...

Biomechanical Evaluation of the Fixation Methods for Transcondylar Fracture of the Humerus:ONI Plate Versus Conventional Plates and Screws [PDF]

open access: yes, 2010
We biomechanically evaluated the bone fixation rigidity of an ONI plate (Group I) during fixation of experimentally created transcondylar humerus fractures in cadaveric elbows, which are the most frequently observed humeral fractures in the elderly, and ...

From fix to fit into the autoptic human brains. [PDF]

open access: yes, 2018
Formalin-fixed, paraffinembedded (FFPE) human brain tissues are very often stored in formalin for long time. Formalin fixation reduces immunostaining, and the DNA/RNA extraction from FFPE brain tissue becomes suboptimal.

Counterintuitive properties of the fixation time in network-structured populations

open access: yes, 2014
Evolutionary dynamics on graphs can lead to many interesting and counterintuitive findings. We study the Moran process, a discrete time birth-death process, that describes the invasion of a mutant type into a population of wild-type individuals ...

Workflow for the Quantification of Soluble and Insoluble Carbohydrates in Soybean Seed

open access: yesMolecules, 2020
Soybean seed composition has a profound impact on its market value and commercial use as an important commodity. Increases in oil and protein content have been historically pursued by breeders and genetic engineers; consequently, rapid methods for their ...

Coherentism and Belief Fixation [PDF]

open access: yes, 2015
Plantinga argues that cases involving ‘fixed’ beliefs refute the coherentist thesis that a belief’s belonging to a coherent set of beliefs suffices for its having justification (warrant). According to Plantinga, a belief cannot be justified if there is a

Evaluation of 10 Edamame Breeding Lines to Determine Yield, Agronomic, and Seed Composition Traits

open access: yesHortScience
Edamame is a vegetable soybean (Glycine max) that is harvested at the R6 growth stage. Although it is relatively new to America, the acreage and market demand of edamame have steadily increased.

Nitrogen Fixation Mutants of the Actinobacterium Frankia Casuarinae CcI3 [PDF]

open access: yes, 2017
Frankia is a representative genus of nitrogen-fixing (N2-fixing) actinobacteria; however, the molecular mechanisms underlying various phenomena such as the differentiation of a N2 fixation-specific structure (vesicle) and the regulation of N2 fixation ...

The propagation of a cultural or biological trait by neutral genetic drift in a subdivided population

open access: yes, 2007
We study fixation probabilities and times as a consequence of neutral genetic drift in subdivided populations, motivated by a model of the cultural evolutionary process of language change that is described by the same mathematics as the biological ...
