Development of empirical relationship between the observed and the estimated ground acceleration values of small to moderate earthquakes in northwest (Gujarat) and northeast (NE) regions of India

open access: yesGeomatics, Natural Hazards & Risk, 2022
We developed empirical relationships between the ground accelerations directly obtained from the strong motion acceleration (SMA) data and the accelerations obtained by differentiating the velocity data from the broadband seismic records of the co ...

Evaluation of Deterministic seismic hazard in Nowshahr Port by using fuzzy system [PDF]

open access: yesمخاطرات محیط طبیعی, 2019
The purpose of the seismic hazard analysis is to predict the extent of the strong ground movements over a certain period of time on a specific site. There are uncertainties in all the inputs of the risk analysis, each of which expresses a property.

Determining disease severity

open access: yesTurkderm Turkish Archives of Dermatology and Venereology, 2022
Assessment of the severity of psoriasis is versatile, and unfortunately, there is no single tool that can assess the severity of this disease in every aspect. As well as psoriasis area and severity index, other tools such as physician’s global assessment

A self-calibration circuit for a neural spike recording channel [PDF]

open access: yes, 2011
This paper presents a self-calibration circuit for a neural spike recording channel. The proposed design tunes the bandwidth of the signal acquisition Band-Pass Filter (BPF), which suffers from process variations corners.

Connections rigidity effect on probability of fracture in steel moment frames [PDF]

open access: yesJournal of Structural and Construction Engineering, 2017
Connections in steel moment frames are idealized in full pinned and full rigid conditions. Because with this assumption, in spite of real behavior of connection, real story drifts are less anticipated and maybe frame is designed without performance of ...

A study of the porosity of nuclear graphite using small-angle neutron scattering [PDF]

open access: yes, 2013
Small angle neutron scattering (SANS) measures porosity in nuclear graphites, including both open pores, caused by escaping decomposition gases, and internal cracks (in coke particles) generated by anisotropic thermal contraction along the c-direction ...

Immobilization and Evaluation of Penicillin G Acylase on Hydroxy and Aldehyde Functionalized Magnetic α-Fe2O3/Fe3O4 Heterostructure Nanosheets

open access: yesFrontiers in Bioengineering and Biotechnology, 2022
Magnetic α-Fe2O3/Fe3O4 heterostructure nanosheets were fabricated via hydrothermal calcination. The activity of penicillin G acylase (PGA), which was covalently immobilized onto silica-decorated heterostructure nanosheets, achieved the highest activity ...

Matrix Metalloproteinases and Glaucoma Treatment. [PDF]

open access: yes, 2020
Matrix metalloproteinases (MMPs) are a family of proteolytic enzymes that degrade extracellular matrix (ECM) components such as collagen and have important roles in multiple biological processes, including development and tissue remodeling, both in ...

Geometric Algebras for Euclidean Geometry

open access: yes, 2016
The discussion of how to apply geometric algebra to euclidean $n$-space has been clouded by a number of conceptual misunderstandings which we first identify and resolve, based on a thorough review of crucial but largely forgotten themes from $19^{th ...
