Optimum Choice of the Front Suspension of an Automobile

open access: yesЖурнал інженерних наук, 2019
The paper details the optimum choice of the front suspension of an automobile. The influence of suspension on the steering geometry is studied by considering the various combinations of joints at the four-bar mechanism of the front suspension.

Optimizing photoexcitation conditions for time‐resolved X‐ray solution scattering experiments

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering (TR‐XSS) is a powerful technique to visualize how proteins change their structure in real time after light activation. Selecting the right laser photoexcitation conditions—fluence, excitation geometry, and sample refresh rate—is critical to maximize the experimental signal while avoiding unwanted side effects ...

Bis(dicyanamido-κN1)bis[2-(2-hydroxyethyl)pyridine-κ2N,O]nickel(II)

open access: yesActa Crystallographica Section E, 2009
In the title complex, [Ni{N(CN)2}2(C7H9NO)2], the NiII ion (site symmetry overline{1}) adopts a distorted trans-NiO2N4 octahedral geometry. In the crystal, intermolecular O—H...N hydrogen bonds link the molecules, forming a chain along the c ...

The geometry of visual experience [PDF]

open access: yes, 2007
In this thesis I examine what the geometry of visual experience is. This is a question which to some has had an a priori answer, and to some its relevance to philosophy has been considered questionable.

De novo synthesis of short‐chain aldehydes and hydrocarbons secreted by the brown marmorated stink bug Halyomorpha halys

open access: yesFEBS Open Bio, EarlyView.
The brown marmorated stink bug, Halyomorpha halys, mainly secretes 4‐oxo‐(E)‐2‐hexenal, (E)‐2‐decenal, dodecane and tridecane, a mixture representative of that released by many heteropterans. We demonstrated that H. halys can synthesise these secretory components de novo using dietary glucose.

Issues in the teaching and learning of geometry

open access: yes, 2002
This chapter analyses a range of key issues in the teaching and learning of geometry. These include the nature of geometry, why geometry is important in the curriculum at school level and beyond, what geometry can be included at the school level, the ...

GelMA‐based 3D spheroids recapitulate transcriptomic and functional hallmarks of myeloid sarcoma

open access: yesFEBS Open Bio, EarlyView.
GelMA 5% hydrogels support the formation of myeloid leukemia spheroids that recapitulate MS‐specific features, including G1 arrest, apoptosis, and ECM‐driven transcriptomic reprogramming. The 3D model mimicked soft‐tissue‐like stiffness and oxygen conditions, and transcriptomic convergence with primary MS samples confirmed its utility as a preclinical ...

trans-Tris(4-bromophenyl)dichloridoantimony(V)

open access: yesActa Crystallographica Section E, 2012
The SbV atom in the title compound, [SbCl2(C6H4Br)3], has an almost regular trigonal–bipyramidal geometry with the equatorial plane made up of three C atoms of the bromophenyl groups and the axial positions occupied by two Cl− ions in

Comparative assessment of crystallographic and cryo‐EM models in the Protein Data Bank

open access: yesFEBS Open Bio, EarlyView.
Raw data obtained by X‐ray crystallography or cryo‐EM result in experimental maps, ultimately fitted by atomic models. Although the physical principles are different, the final results can be viewed, compared, and evaluated in the same way. With cryogenic electron microscopy (cryo‐EM) on track to surpass X‐ray crystallography as the preferred method ...
