Graphene Oxide‐Based Gene Modulation in Preferential Elimination of Lung Cancer Cells in a 3D Tumor Microenvironment Model

open access: yesAdvanced NanoBiomed Research, EarlyView.
Chemically modified graphene oxide nanocarriers provide a targeted lung cancer gene therapy platform. In a 3D tumor microenvironment model, these nanocarriers deliver therapeutic genes, regulate immune markers, and induce apoptosis in cancer cells. Combined gene delivery enhances cancer cell elimination, demonstrating the potential of this approach for

Observation of an upward lightning flash with 21 upward positive leaders initiated from different wind turbines in wind farm

open access: yesHigh Voltage
As the wind turbine height increases, the probability of multiple upward leaders flashes within the wind farm increases. In this study, an upward lightning flash containing 21 upward positive leaders (UPLs) initiated from different wind turbines in ...

Snake and Moon ‘Right Way Marriage’ Stories on Stone and Bark

open access: yesArchaeology in Oceania, EarlyView.
ABSTRACT In northwest Australia, boab trees hold significant cultural values for First Nations people. Their leaves, bark, roots and nuts are important as traditional resources for food, medicine, fibre, water and shade and serve as reference points in the landscape. Some of the tree trunks are inscribed with images and symbols which tell of events and

Analysis of Conditions favorable for Ball Lightning Creation [PDF]

open access: yesarXiv, 2016
This report uses a few well documented cases of Ball Lightning (or BL for short) observations to demonstrate a correlation between BL and positive lightning, especially strong positive lightning. This allows to draw conclusions and predictions about future BL observations and the pro- duction of these objects in the laboratory. Contrary to many current

Evaluation of the damages caused by lightning current flowing through bearings [PDF]

open access: yes
A laboratory for lightning current tests was set up allowing the generation of the lightning currents foreseen by the Standards. Lightning tests are carried out on different objects, aircraft materials and components, evaluating the direct and indirect ...

Analysis of existing effectiveness and method to enhance the lightning, shielding and earthing protection schemes applied on the Parit Raja’s Telecommunication Tower System [PDF]

open access: yes, 2013
Lightning, one of nature’s most destructive forces, continues to wreck havoc on lives and property especially in today’s electronic environment. It has been shown by field experiences that telecommunication towers are one of the preferential points

A fractal model for the lightning induced current on a transmission line [PDF]

open access: yes, 1997
This article presents a model of a tortuous lightning channel, and a study of the consequent electromagnetic coupling to a transmission line. We analyse the fractal dimension of the induced current on the line, compared with the fractal dimension of the ...
