A Dual-PRF Scan Mode and Adaptive Doppler-Velocity Dealiasing to Increase Radar Clear-Air Velocity Data Coverage and UsabilityAbstract
By using long pulses with extended dwelling time, lowered pulse repetition frequency (PRF) and reduced Nyquist velocity, the radar measurement capability can be enhanced to increase clear-air Doppler velocity data coverage (which is beneficial for radar wind analysis and data assimilation and motivated our previous study). This potential capability is further explored (beyond our previous study) by not only modifying the existing operational clear-air scan mode with a lowered PRF and reduced the Nyquist velocity (t [...] 1123 8029 |
An Estimate of Possible Impacts of Superoxide Chemistry on Seawater pH: A Mapping ExerciseAbstract
Superoxide, produced photochemically as well as microbially, is an important reactant present in seawater and a major source of hydrogen peroxide. Superoxide decay may occur through catalyzed or uncatalyzed dismutation forming H2O2 and O2, through oxidation to O2, or through reduction into H2O2. Under definite circumstances, the redox processes that are different from dismutation could produce or consume H+, thereby altering the pH of seawater. In order to alter the pH, these processes have to involve, together wit [...] 1283 8018 |
The Effects of Mediterranean Diet on the Human Gut Microbiota; a Brief Discussion of Evidence in HumansAbstract
The Mediterranean diet (MD) is considered one of the healthiest dietary patterns due to its rich provision of phytochemicals, antioxidants, vitamins, fiber, polyunsaturated, omega-3, and short-chain fatty acids through a variety of foods. The supply of such nutrients and bioactive components can support gut health and reduce systemic inflammation, with accumulating evidence from several human studies demonstrating the utility of the Mediterranean diet in the prevention of chronic and metabolic diseases. Further stu [...] 1391 8018 |
Arterial Elasticity: Linking of Cardiovascular Risks, Pulse Pressure, Dementia, Aging, and Drug TargetingAbstract
Cerebrovascular atherosclerosis, and several other cardiovascular (or "inflamm-aging" type) diseases, are more frequent and advanced in subjects with Alzheimer's disease compared with normal aging. In addition, the observed pathogenic link to dementia (and its associated cerebral microvascular damage) is readily explained by alterations of arterial elasticity. A therapeutic strategy to delay dementia could be based upon localized drug delivery, using lipid nanocarriers (i.e., biobased nanoemulsion technology), targ [...] 1063 8009 |
Influence of Biogas Digestates on the Composition of Soil Organic MatterAbstract
The increasing number of biogas plants with various digested organic materials and output of digestates calls for more detailed investigations of their suitability as soil amendments. In a trial in Northern Germany two replicate plots each were treated with fresh or prolonged fermented digestate to investigate the influence of digestates on the composition of soil organic matter (SOM). The relative proportions of relevant SOM compound classes were determined by pyrolysis-field ionization mass spectrometry (Py-FIMS) [...] 1354 8008 |
Greater Objective and Perceived Competence for Clinics is Associated with Reduced Stress but No Change in Impostorism in Medical Students aAbstract
Impostorism is prevalent in medical students and negatively impacts wellness, contributing to stress and burnout. Perceived competence is noted as one attribute underlying impostorism. A curricular change that resulted in improved United States Medical Licensing Examination (USMLE) Step 1 scores and student self-perceptions of preparedness for clinical training was used as a natural experiment to assess the effects higher competence/preparedness, based on an objective indicator and self-perceptions, on impostorism, [...] 1275 8005 |
Groundwater Artificial Recharge Potentiality in Al-Qilt Catchment Jericho – West Bank – Palestineby
Abstract
The main research objective is to highlight the potentiality of artificial groundwater recharge in Al-Qilt catchment- Jericho - Palestine regarding the water shortage in the groundwater-supplied areas. Artificial recharge can be a possible option in increasing the storability of the underground aquifer, which will add values to the Palestinian strategy to optimize the total accessibility of groundwater resources. The increase of water demands and the scarcity of water resources in the Jordan Rift areas are putting [...] 1071 8000 |
Towards Femtoscan-Assisted Analysis of Liquid Crystal Self-Organization on Different Polymer and Glass Surfaces for Lab-on-a-Chip and Lab-on-a-Dish Applications, Including Optofluidic and Flexoelectric Onesby
Abstract
In this paper, starting with an introductory review of the applications of liquid crystals and polymer-dispersed liquid crystal systems in (bio)sensors and microfluidics, the possibilities of visualizing self-organization products of liquid crystalline media or field-induced instabilities of liquid crystalline systems are considered. In particular illustrated cases, it is proposed to use FemtoScan software-containing metrological complexes to visualize instabilities in liquid crystalline systems and products of sel [...] 1763 8000 |
Efficient Industrial Wastewater and Leachate Evaporation Utilizing Heat Localization in Porous MediaAbstract
In this paper, an efficient industrial wastewater and leachate evaporation method is proposed and tested experimentally. The goal of this study is to investigate whether the addition of a carbon foam (CF) porous layer can lead to energy savings by evaporating more water mass per unit of energy input. The standard boiling evaporator layout was redesigned by placing the heating element in the upper region of the tank and CF underneath the heat source. The CF purposed to localize the energy in an area by the water' [...] 1315 7995 |
