Experimental Measurements and Computer Simulation of Fission Product Gamma-Ray Spectra [PDF]

, 1997
Airborne gamma ray spectrometry using high volume scintillation detectors, optionally in conjunction with Ge detectors, has potential for making rapid environmental measurements in response to nuclear accidents. An experimental investigation and computer

Testing Non commutative QED gamma-gamma-gamma and gamma-gamma-gamma-gamma Couplings at LHC [PDF]

The European Physical Journal C, 2004
In this work, we investigate the sensitivity of the process p + p --> q + q --> j + j + gamma + gamma at LHC for the photonic 3- and 4- point functions that appear in non commutative QED. We show that this process serves to study the behavior of the space-space as well as of the space-time non commutativity.

Use of Machine Learning Models for Prediction of Organic Carbon and Nitrogen in Soil from Hyperspectral Imagery in Laboratory

Journal of Spectroscopy, 2023
Organic carbon and total nitrogen are essential nutrients for plant growth. The presence of these nutrients at acceptable levels can create an optimal environment for the development of crops of interest.

The role of Gamma Knife radiosurgery in the management of skull base chordoma

Frontiers in Oncology, 2023
ObjectiveChordoma is a slow-growing and locally aggressive cancer, which arises from the remnants of the primitive notochord. The first line treatment for the skull base chordoma is neurosurgery.

Repeat gamma knife radiosurgery for cavernous sinus hemangiomas: A report of 3 cases

Interdisciplinary Neurosurgery, 2021
Background: Gamma knife radiosurgery(GKS) is well established in the management of cavernous sinus hemangiomas(CaSHs) alternative to microsurgery. Tumor regrowth is occasionally encountered and the role of repeat GKS in these situations is still unclear.

Celiac disease and primary hyperparathyroidism

Revista de la Facultad de Ciencias Médicas de Córdoba, 2023
Objective. Primary hyperparathyroidism (PHPT) and celiac disease (CD) are two distinct medical conditions that can affect bone health. While PHPT leads to excessive calcium levels and bone abnormalities, CD impairs calcium and vitamin D absorption due ...

Niveles de 25(OH)D durante la pandemia de COVID-19: impacto del confinamiento y la radiación ultravioleta

Gaceta Médica de México, 2023
Antecedentes: Las políticas de confinamiento domiciliario durante la pandemia de COVID-19 limitaron la exposición solar y pudieron influir en los niveles de vitamina D. Objetivo: Evaluar los cambios en 25(OH)D durante la pandemia de COVID-19 y el impacto

The $\gamma \gamma \to A^0 A^0 $ process at a $\gamma \gamma $ collider [PDF]

The European Physical Journal C, 2000
The helicity amplitudes for the process $\gamma \gamma \to A^0 A^0$ are studied to 1-loop order in the minimal SUSY (MSSM) model, where $A^0$ is the CP-odd Higgs particle. Simple exact analytic formulae are obtained, in terms of the $C_0$ and $D_0$ Passarino-Veltman functions; in spite of the fact that the loop-diagrams often involve different ...
