in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
This paper introduces a novel drying system called ohmic assisted (OAD) – the simultaneous combination of heating and convectional air drying. The OAD improved characteristics potato slices. Depending on process conditions, time was shortened by 20–60% compared to conventional air-drying system. level applied voltage temperature were effective reduction. To achieve better understanding changes ...
The Development and Assessment of a Herbal Floating Tablet for Peptic Ulcer Disease. goal creating herbal floating tablet is to extend the drugs duration in gastrointestinal tract. This will increase bioavailability result greater absorption than with convectional dose form. Due its gastro-retentive feature, medicine remains at site inflammation longer amount time, resulting more targeted actio...
Abstract Previous numerical simulations have shown that strong winds can be produced in the hot accretion flows around black holes. Most of those studies focus only on region close to central hole; therefore it is unclear whether wind production stops at large radii Bondi radius. Bu et al. (2016) studied flow radius presence nuclear star gravity. They find that, when stars gravity important–com...
During the COVID-19 pandemic, conventional education revolution to technology-based became world's spotlight. Online learning activities are one of most effective solutions in Indonesia during pandemic. The government has begun transitiofrom face-to-face (convectional learning) distance (online through. Blended best options that can be implemented pandemic situation. Learning ability improve st...
Abstract Removal of pollutants produced by industrial plants requires reusing water and access to the environment standard. The chemical coagulation process is a convectional method for wastewater treatment reduce oxygen demand total suspend solids. objective this work study effect initial pH, coagulant type, dosage used on separation performance at different oil concentrations. Based result, 8...
This paper presents the designed method and implementation of stepped air-gap ferrite inductor applied in power factor correction (PFC). Conventionally, input PFC has a consideration on maximum output power; thus, designing for peak-power-load conditions results very large inductor. The proposed improves load-carrying capability without increasing volume when is operating conditions. maintains ...
In infrastructure-as-a-service platforms, cloud users can adjust their database (DB) service scale to dynamic workloads by changing the number of virtual machines running a DB management system (DBMS), called DBMS instances. Replicating instance is non-trivial task since replication time-consuming due trend that vendors offer high-spec This paper presents BalenaDB, which performs urgent for han...
