Deadly Ultraviolet UV-C and UV-B Penetration to Earth’s Surface: Human and Environmental Health Implications | Chapter 02 | Current Perspectives to Environment and Climate Change Vol. 1

Aims: The dangerous portion of ultraviolet radiation is widely believed to be completely absorbed by the atmosphere before reaching Earth’s surface. Our objective is to make multiple measurements at Earth’s surface of the solar irradiance spectrum in the range 200-400 nm.

Methods: We made numerous measurements of the solar irradiance spectrum in the range 200-400 nm at an elevation of 56 m with International Light Technologies ILT950UV Spectral Radiometer mounted on a Meade LXD55 auto guider telescope tripod and mount assembly.


Results: Our multifold measurements of solar irradiance spectra demonstrate conclusively that all wavelengths in the spectral range 200-400 nm reach Earth’s surface, contrary to the widespread perception that all UV-C and the majority of UV-B never reach the surface. We confirm the surface UV-C measurements of D’Antoni et al. (2007) that were disputed, based on faulty computer model calculations of atmospheric ozone, and thereafter ignored by the geoscience community.

Conclusions: The veracity of our data and D’Antoni et al. (2007)’s data call into question the validity of atmospheric ozone models. Further, we call into question the simplistic supposition of the Montreal Protocol that chloro-fluoro-hydrocarbons are the primary cause of ozone depletion, and point to the very heavy burden of halogens introduced into the atmosphere by ongoing jet-sprayed coal-fly-ash geoengineering. We demonstrate that satellite-based LISIRD solar spectra irradiance at the top of the atmosphere is badly flawed with some regions of the spectrum being less intense than measured at Earth’s surface. That calls into question any calculations made utilizing LISIRD data. We provide introductory information on the devastating effects of UV-B and UV-C on humans, phytoplankton, coral, insects and plants. These will be discussed in greater detail in subsequent articles.

Greening Regional Airports: A Vision for Carbon Neutral Infrastructure | Chapter 12 | Contemporary Perspective on Science, Technology and Research Vol. 3

 This study provides an overview of the energy demand of a regional airport, divided into individual time horizons. The electrification of aircraft systems raises the question of whether airports will be among the largest electricity consumers in our infrastructure in the future. Sustainability and especially emission reductions are significant challenges for airports that are currently being addressed. The Clean Sky 2 project GENESIS addresses the environmental sustainability of hybrid-electric 50-passenger aircraft systems in a life cycle perspective to support the development of a technology roadmap for the transition to sustainable and competitive electric aircraft systems. This article originates from the GENESIS research and describes various options for ground power supply at a regional airport. Potential solutions for airport infrastructure with a short (2030), medium (2040), and long (2050) time horizon are proposed. In addition to the environmental and conservation benefi...

There is No Standard Model of ZFC and ZFC2 | Chapter 03 | Advances in Mathematics and Computer Science Vol. 1

In this Chapter we obtain a contradictions in formal set theories under assumption that these theories have omega-models or nonstandard model with standard part. An possible generalization of Lob’s theorem is considered. Main results are: (i) ¬Con(ZF C+ ∃ M ZFC st ), (ii) ¬Con(N F+ ∃ M NF st ), (iii) ¬Con(ZF C 2 ), (iv) let k be an inaccessible cardinal then ¬Con(ZF C+ ∃ κ), (v) ¬Con(ZF C+ (V=L)), (vi) ¬Con(ZF+ (V=L)).

Occipital Dermal Sinus Tract Causing Craniospinal Infection: A Review | Chapter 13 | New Visions in Medicine and Medical Science Vol. 4

  Dermal sinus is a rare congenital condition characterized by a pathological tract connecting the skin to deeper tissues of the central nervous system, potentially leading to severe infectious complications. It arises from a failure in the separation of ectodermal layers during early gestation. Diagnosing dermal sinus tract in newborns requires a careful physical examination, focusing on midline dimples in the occipital region associated with cutaneous abnormalities like hairy nevus or hyperpigmentation. The presence of drainage, abnormal hair distribution, or localized swelling may indicate a sinus tract. Regular examination for dimples or sinuses is recommended for infants and children with recurrent meningitis or infections. Early detection is crucial to prevent severe complications like meningitis, with Staphylococcus aureus being a common causative organism. Neuroradiological studies, including computed tomography (CT) scan and magnetic resonance imaging (MRI), with histopath...
