Learning physics should be able to provide an understanding physics of abstract concepts.One of the efforts being made to improve the learning of Physics is to use appropriate learning model.This study aims to improve the studentââ¬â¢s conceptual understanding by using project based learning model with virtual media for X Grade student a
With increase in cost of gaseous fuels and depletion in their reserves, it has become essential to further improve the efficiency of the commercial gaseous burners which generally have low thermal efficiency and high emissions.Porous Radiant Burner (PRB) is one such emerging technology which assists lean combustion, thus yielding clean burning and
Background Throughout the COVID-19 pandemic, testing individuals remains a key action.One approach to rapid testing is to consider the olfactory capacities of trained detection dogs.Methods Prospective cohort study Cars in two community COVID-19 screening centers.Two nasopharyngeal swabs (NPS), one saliva and one sweat samples were simultaneously c
BACKGROUND: Rye (Secale cereale L.) is an economically important crop, exhibiting unique features such as outstanding resistance to biotic and abiotic stresses and high nutrient use efficiency.This species presents a challenge to geneticists and breeders due to its large genome containing a high proportion of repetitive sequences, self incompatibil
In order to use efficiently barley varieties for such purposes as food, fodder and brewing, an objective and thorough study of grain quality is of great necessity, with adjustment for the features of hulles varieties.The purpose of the current study was to estimate the biochemical and technological indicators of grain varieties of hulled and hulles
