This paper investigates the local and global ionospheric responses to 2022 Tonga volcano eruption, using ground-based Global Navigation Satellite System (GNSS) total electron content (TEC), Swarm in-situ plasma density measurements, Ionospheric Connection Explorer (ICON) Ion Velocity Meter (IVM) data, ionosonde measurements. The main results are as follows: (1) A significant hole of more than 1...

OI 630.0 nm airglow observations, from a new observatory at Bom Jesus de Lapa, were used to study the interaction between EPBs (Equatorial Plasma Bubbles) and MSTID (Medium-Scale Traveling Ionospheric Disturbance) over Northeast region in Brazil. On night of September 16 17, 2020, an EPB was observed propagating eastward, apparent fossil stage, until it interacted with dark band electrified (eM...

Equatorial Plasma Bubbles (EPBs) are irregular plasma density depletions in the ambient electron equatorial F-region ionosphere generated after sunset. EPBs known to bring disruptions telecommunication and navigation systems. This paper investigates occurrence of over Kisumu, Kenya (Geomagnetic coordinates: 9.64o S, 108.59o E; Geographic 0.02o 34.6o E) for a few selected quiet storm days betwee...

Several disconnects serve to weaken the use of evidence based programming in community settings. Communities face the need to address the challenges of multiple risk behaviors faced by adolescents in their communities, but must also work to support successful transitions to adulthood and the broader positive development of their youth. The stronger integration of positive youth development and ...

Implementing specific evidence-based practices (EBPs) across a set of addiction treatment providers have been a persistent challenge. In the Advancing Recovery(AR) demonstration project, single state agencies, the entities that distribute federal funds for substance use disorder prevention and treatment services, worked in partnership with providers to increase the use of EBPs in the treatment ...

In response to the sustainable development goal of agriculture put forward by United Nations, countries have introduced a series agricultural environmental protection policies. However, effectiveness these policies has been hindered insufficient responses from farmers. This study begins with fundamental logic farmers’ production behavior and first introduces family place identities into theoret...

Recently, the search for novel products derived from natural sources has become necessary due to decreasing effectiveness of current antibiotics in treating bacteria that are antibiotic-resistant. In this context, it is well known entomopathogenic (EPBs) produce a broad range secondary metabolites with antibacterial activities. Therefore, an in-vitro trial was conducted isolate and identify non...
