Effect of magnification and field of view on reading speed using a CCTV

, 1987
Reading speeds were measured in 18 subjects with normal vision and 10 with low vision for each of 20 experimental conditions with different magnifications and field sizes on the Closed Circuit Television System (CCTV). There was a significant difference

Magnification factors for hingeless arches.

, 1958
This thesis presents a simple method for the determination of bending moments in flexible symmetrical hingeless arches. The deflection theory bending moments are obtained by multiplying elastic theory bending moments by predetermined magnification ...

Purification and preparation of Marchantia polymorpha Auxin Response Factor 2 for phase separation studies

FEBS Open Bio, EarlyView.
We describe detailed protocols for the purification and preparation of Marchantia polymorpha Auxin Response Factor 2 (MpARF2). This protein is fused to an MBP solubility tag and an mNG fluorescent tag and is purified from Escherichia coli. The presented procedures make it possible to study MpARF2 assemblies, which could arise from phase separation ...

Exploring Weak Gravitational Lensing Effects by a Regular Black Hole

Spektra: Jurnal Fisika dan Aplikasinya
Gravitational lensing is one of the physical consequences of Einstein’s general theory of relativity, which has been observationally confirmed. This work aims to study the weak gravitational lensing scenario where the lens is a spherically symmetric ...

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

FEBS 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 ...

Physical magnification of objects

, 2018
For hundreds of years, scientists have aimed photons, electrons, and X-rays at objects in order to obtain magnified images of them, revealing their micro- and nanoscale architecture, and revolutionizing every branch of the sciences.

Enhancing Precision in Endodontic Procedures: An In vitro Investigation of Magnification and Enhanced Visualization

Journal of Pharmacy and Bioallied Sciences
Background: Endodontic procedures require precise manipulation and visualization to achieve optimal treatment outcomes. Magnification and enhanced visualization tools, such as dental loupes and dental operating microscopes (DOMs), have been introduced to

MAGNIFICATION IN MICROSCOPIC LENSES

American journal of optometry and archives of American Academy of Optometry, 1969
ABSTRACT Patients with best corrected visual acuity between 20/50 and 20/200 arc very often helped by using high reading additions or so‐called “microscopic” lenses. Because they are rated in magnification units based on a reference distance of 25 centimeters, these lenses arc frequently ...

Identification and characterisation of calcitonin receptor isoforms expressed in glioblastoma derived glioma stem and U‐87 MG cells

FEBS Open Bio, EarlyView.
Glioblastoma cells express calcitonin receptor variants (CT receptor isoforms) that may help them survive stress. Using qPCR, transcript‐specific long‐read nanopore sequencing, immunofluorescence co‐localisation and comparative sequence analysis, this study identifies a novel alternatively spliced CALCR transcript that encodes the CTb receptor isoform ...

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

FEBS 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 ...
