Systematic biases in human heading estimation. [PDF]

open access: yes, 2013
Heading estimation is vital to everyday navigation and locomotion. Despite extensive behavioral and physiological research on both visual and vestibular heading estimation over more than two decades, the accuracy of heading estimation has not yet been ...

Breeding and genetic aspects of creating productive forms of fast-developing spring bread wheat

open access: yesТруды по прикладной ботанике, генетике и селекции, 2019
Background. In Russia, wheat breeding should also focus on creation of earlier-maturing varieties with an optimal duration of the vegetation period reflecting territorial environmental features.

Identification of QTLs associated with grain-filling duration and heading date in wheat [PDF]

open access: yesBrazilian Journal of Biology
An increase in genetic diversity of bread wheat caused by spring x winter forms leads to an alteration of genetic control of maturity time. Maturity time (MAT) is one of major yield components in wheat, which has two components: the heading date (HD) and

An Accurate Heading Solution using MEMS-based Gyroscope and Magnetometer Integrated System (Preliminary Results) [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2014
An accurate heading solution is required for many applications and it can be achieved by high grade (high cost) gyroscopes (gyros) which may not be suitable for such applications.

Genetic Factors Associated with Heading Responses Revealed by Field Evaluation of 274 Barley Accessions for 20 Seasons

open access: yesiScience, 2020
Summary: Heading time is a key trait in cereals affecting the maturation period for optimal grain filling before harvest. Here, we aimed to understand the factors controlling heading time in barley (Hordeum vulgare).

Analysis of VRN1 gene in triticale and common wheat genetic background

open access: yesScientia Agricola, 2014
In cereals, the transition from the vegetative stage to flowering is controlled in the main by the set of vernalization genes. Within these genes the most important role is played by VRN1, which encodes a MADS-box transcription factor, regulating the ...

Purposeful soccer heading exposure and clinical outcomes in youth soccer players

open access: yes, 2022
Kaminski, Thomas W.Background: Soccer is a popular youth sport in the United States and around the world and is unique in the fact that players can use their heads to advance the ball in play; a skill known as heading.

Model-based tests on the time of crew evacuation from the danger area in an excavated underground mine heading [PDF]

open access: yesE3S Web of Conferences, 2020
When ventilation hazards become active in an underground mine heading, it is very often necessary to evacuate the crew from the danger area. This evacuation is carried out along emergency escape (evacuation) routes to a heading which is not affected by a

The Effect of Ambient Temperature on Brachypodium distachyon Development

open access: yesFrontiers in Plant Science, 2019
Due to climate change, the effect of temperature on crops has become a global concern. It has been reported that minor changes in temperature can cause large decreases in crop yield.

Introgression of chromosomal segments conferring early heading date from wheat diploid progenitor, Aegilops tauschii Coss., into Japanese elite wheat cultivars. [PDF]

open access: yesPLoS ONE, 2020
The breeding of agriculturally useful genes from wild crop relatives must take into account recent and future climate change. In Japan, the development of early heading wheat cultivars without the use of any major gene controlling the heading date is ...
