Monte-Carlo Modelling For Evaluation Of Two Different Calculation Algorithms

Brazilian Journal of Radiation Sciences, 2019
Modeling of linac head (VARIAN Trilogy) for 6 MeV photon beam was performed using BEAMnrc code package (BEAMnrc 2017). The DOSXYZnrc code was used to determine the percentage depth dose (PDD profiles) and beam profiles for different symmetric square ...

From the sea to DNA barcode: Optimized preservation method for gelatinous zooplankton integrative taxonomy

Limnology and Oceanography: Methods, EarlyView.
Abstract Assigning taxonomic identity and thus assessing taxonomic diversity in gelatinous zooplankton is challenging due to their fragility and difficult preservation. Formalin fixation compromises DNA integrity, while flash‐freezing, ethanol, and acetone preservation affect morphological features. In this study, we developed a methodological protocol

Sustainability and Corporate Performance in the Global South: The Influence of the Environmental Pillar and Institutional Quality

Sustainable Development, EarlyView.
ABSTRACT Corporate sustainability in the Global South unfolds under heterogeneous institutional conditions, where firms face simultaneous pressures from global ESG standards and local governance constraints. This study examines the relationship between ESG‐aligned environmental practices and corporate financial performance, considering the moderating ...

Analysis of thyroid absorbed dose in cervical CT scan with the use of bismuth shielding

Brazilian Journal of Radiation Sciences, 2019
The Computed Tomography (CT) has become an important tool to diagnose cancer and to obtain additional information for different clinical questions. Today, it is a very fast, painless and noninvasive test that can be performed high quality images. However,

Crossroads of the Life of Vittorio Alfieri

Journal for Eighteenth-Century Studies, EarlyView.
Abstract This article examines Vittorio Alfieri's Life as a deliberately constructed narrative of cultural, linguistic, and political self‐fashioning within eighteenth‐century European intellectual networks. Rather than treating the autobiography as a transparent record of experience, the article argues that Alfieri retrospectively reorganizes his ...

Tumor and Critical Organ Dose Assessment in Parotid Gland Radiotherapy: Comparison of Calculated and Measured Dose Using Different Techniques [PDF]

Iranian Journal of Medical Physics
Introduction: Parotid gland tumors account for approximately 3% of head and neck malignancies. Surgery is the primary treatment modality, while postoperative radiotherapy is recommended for high-grade tumors to reduce local recurrence.

A Dual Cell‐Line Molecular Platform to Assess Sub‐Threshold Biocompatibility: Application to Processed Orthodontic Clears Aligners

Orthodontics &Craniofacial Research, EarlyView.
ABSTRACT Objective Traditional biocompatibility assessments primarily address cytotoxicity and bulk material properties but often overlook molecular responses that occur below toxicity thresholds. Detecting these subtle effects is crucial for materials intended for prolonged contact with human tissues.

Hypoxia and hypercapnia elicit overlapping but distinct skeletal muscle toxicities

The Journal of Physiology, EarlyView.
Abstract figure legend Hypoxia and hypercapnia cause overlapping skeletal muscle phenotypes, including atrophy, change in myofibre metabolic profile and myogenic response to injury. Both signals operate via distinct cellular pathways. Abstract Skeletal muscle dysfunction is strongly associated with elevated mortality in acute and chronic pulmonary ...

Treating age‐related loss of muscle mass and function: Where should we be focusing?

The Journal of Physiology, EarlyView.
Abstract figure legend Perturbations contributing to the age‐related loss of muscle mass and strength. A, in the spinal cord, self‐reinforcing cycles of oxidative stress, mitochondrial dysfunction and inflammation mediated by cells, including microglia, contribute to motor neuron degeneration.
