Impacts of Flood Simulation in 3D and SWAT Environment of Terengganu River Catchment | Chapter 04 | Advances in Applied Science and Technology Vol. 1

Flood is a natural hazard  influenced by climatic and  anthropogenic factors.  The Terengganu  River catchment is located near the South China Sea has been flooding during heavy monsoon season with strongrain-bearing  winds  to  the  interior  coastal  zones  of  Kuala  Terengganu.  The  ArcSWAT2012extension  of  ArcGIS10.3  and  ArcScene10.3  has  been  used  to  design  3D  models  simulations  to predict flood risk event through the stream flow and elevation data derived from ASTER DEM. The Hydrologic Response Units (HRUs) provided the sub-basins parameters which are overlaid with the real-time simulations to determine which sub-basins are affected by flood risk. The flood animation is developed for mitigation and quick decision making for safety and evacuation of flood victims in the Terengganu River catchment. The 3D simulations produce flood risk zones models which illustrate the affected zones by the flood. The 25 sub-basins parameters have distinct characters which influence the  stream  flow,  soils,  slopes  and  land  cover.  That  represent  areas  affected  by  flood  in  Kuala Terengganu. The 25 sub-basins parameters have unique characteristics that influence the river flow, land  cover,  soil  and  slopes.  One  of  the  effective  ways  offlood  monitoring  is  to  see  it  physically occurring  or  happening  in  real-time.  The  solution  is  to  set  the  model  at  the  simulation  in  the  3D environment. The Terengganu River catchment was successfully delineated and simulated using the sub-basins to identify zones that are affected by the flood risk. The impacts of flood risk usually take place during the monsoon period, especially in Peninsular Malaysia. The Terengganu catchment is liable to flooding  during the period of monsoon. The average rainfall during flash  flood reaches to 3000mm of rain, with more than 24 hours of a continuous heavy rain shower. The flood event mostly affects peninsular Malaysia from Decembers to January.

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...

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...

Alkali Element Modification of Glucose Molecules as a Method to Dissolve Cancer Cells | Chapter 12 | New Visions in Medicine and Medical Science Vol. 4

  The present study highlights about alkali element modification of glucose molecules as a method to dissolve cancer cells. The central regulation of the mechanisms governing cell proliferation has little effect on cancer cells. Cancer cells are entirely independent of the central command and divide and proliferate on their own, making it challenging to activate their response mechanism. Precisely, this is the reason why they are at risk to the health of humans and/or any biological entities. Instead of trying to reconnect the central command of the growth control mechanism to cancer cells that are already out of the range, we present a method of using the cancer cell’s own irresponsive and uncontrolled growth mechanism to their disadvantage and destroy the cancer cells. We found that this is achievable in an atomic/molecular level study of the glucose molecule, which is the primary food source used for growth and energy generation by all cells in the body, including the cancer cel...
