Population genetics of P transposable elements and their host species, with emphasis on Drosophila willistoni and Drosophila sturtevanti
… (subgenus Sophophora). The transmission of P elements among species, their spread within species and the strength of selective constraints, as well as the level at which they are imposed on these elements, were investigated using DNA sequence data. Particular emphasis was placed on the …

OMB and ORG-1
… but failed to target org-1. The closest P elements are still 10 kb away from org-1. Subsequently, we employed org-1 flanking P elements to induce precise deletions in 7E-F spanning org-1. Two org-1 flanking P elements were brought together on a recombinant chromosome. Remobilization of P …

Understanding Host Tolerance to Transposable Elements
Transposable elements (TE) are mobile genetic parasites, whose unregulated activity in germline causes DNA damage, and results in sterility. Host genomes can avoid these fitness costs of TEs either by regulating TE proliferation, or by altering gametogenesis to tolerate TE-induced DNA damage. …

Production of temporary bone scaffold reinforced with OPEFB-CMC from oil palm empty fruit bunch
… in attracting Calcium (Ca) and Phosphate (P) elements for apatite layer development on its surface was also proven with the calculated value of Ca/P ratio that has identical value with the theory, at 1.67.

Hot ductility and its relationship to transverse cracking in steels
… Si (0.1 to 0.5%Si) and P, (0.001 to 0.025%P). Elements that raise the Ara e. g. Si and P were found to lead to recovery in ductility at slightly higher temperatures at the low temperature end of the trough. However, reducing C levels to <0.1C had the most pronounced influence on hot ductility …

Responses to transposon activity and genome damage during germline development
… where genetic conflicts between selfish genetic elements, like transposons, and the host genome take place. Excessive transposon activity fulfils the selfish drive of transposons to increase in copy number in the host genome but can impair genome integrity and functionality, thereby threatening …

MOTIVIC HOCHSCHILD HOMOLOGY
… Z/p are a polynomial ring over the field with p elements on a single generator τ in bidegree (0,-1). To do so, we introduce a tri-graded spectral sequence in motivic homotopy groups inspired by an analogue in stable homotopy theory defined by J. Greenlees in a 2016 paper. We will use our spectral …
