the present study was conducted to determine the relative contribution of initial quality and compositional parameters to the rate of changes (rctpc) in the content of total polar compounds (tpc), which is considered to be one of the most reliable indicators of heated oils quality, of olive oil during continuous heating at 180 ºc. the ratio between monounsaturated and polyunsaturated fatty acid...

BACKGROUND Preparation of nanoformulations using natural products as bioactive substances is considered very promising for innovative larvicidal agents. On this context, oil in water nanoemulsions develop a main role, since they satisfactorily disperse poor-water soluble substances, such as herbal oils, in aqueous media. Pterodon emarginatus, popularly known as sucupira, has a promising bioacti...

sakhtehesar mountain is located in urumieh-dokhtar magmatic belt and is composed of volcanic and subvolcanic rocks (pliocene andesite to dacite) which intruded the volcanics and pyroclastics of paleocene age. three alteration zones including potassic, phyllic and propylitic are recognized in the area. in this paper, the mineral chemistry of magmatic and primary biotite and the mineral chemistry...

UNLABELLED Studies show a high prevalence of vocal alterations among teachers. One of the criteria for the establishment of the prevalence of vocal alteration is based on teachers' self-perception. OBJECTIVE This study aimed at comparing voice-disordered quality of life measures between a group of teachers who reported vocal alteration and a group of teachers who did not, by verifying the tea...

The conversion of vegetation land cover contributes to the retention solar radiation in environment, resulting formation urban heat island. This study analyses distribution pattern island traditional core Ibadan amidst rapid urbanization experienced. remote sensing tool was used analyse trend surface temperature, normalized difference built-up index, and index for Ibadan's between year 2000 202...

We aimed to assess the accuracy of Doppler tissue imaging (DTI) in detecting right ventricle (RV) dysfunction and electromechanical coupling alteration following pulmonary hypertension (PHT) in rat. PHT was induced by chronic hypoxia exposure (hypoxic PHT) or monocrotaline treatment (monocrotaline PHT). In both PHT models, we observed transparietal RV pressure increase and remodeling, including...

Ledokombo hillocks are small hills located in Jember, East Java that have natural resources and face habitat alteration such as plantation mining. However, a study of the diversity butterflies has not been carried out this area. We analysed using Shannon-Wiener index (H’) Pielou evenness (E). identified 514 individuals from 34 species demonstrated moderate (H'= 1.907) Our results could be used ...

Abstract Utility of the geothermal surface manifestations (GSMs; thermal springs, geysers, fumaroles, and zones hydrothermal alteration) in studies related to exploration is widely recognized. The identification hydrothermally altered rocks alteration very important because their presence indicates type size reservoir existing conditions. use traditional methods (i.e., geochemistry, mineralogy,...
