Terminalia catappa and subspathulata are two species of the Combretaceae family medium to large forest trees. The fruits T. known for edible nuts commonly as tropical almonds due their similarity in taste with commerce. Therefore, chemical profiles were examined ascertain potential value food or health uses. Gas chromatography-mass spectrometry (GCMS) ultrahigh-pressure liquid chromatography-el...

Suhu kolom Gas Chromatography-Mass Spectrometry (GCMS) merupakan salah satu variabel yang harus diperhatikan pada analisis senyawa kimia, agar terpisahkan dengan baik. Penelitian ini bertujuan untuk menentukan suhu terprogram optimum asam lemak menggunakan instrumen GCMS. Sampel digunakan berasal dari hasil ekstrak mikroalga Chlorella. Ekstrasi Chlorella dilakukan cara sonikasi selama 60 menit ...

during the 1970s made possible the observation of the seasonally shifting patterns of global precipitation. It was not until recently, however, that the record could be considered long enough to investigate longer-term trends and the relationship between global precipitation and global warming. Using data from the Special Sensor Microwave Imager (SSM/I) instrument, Wentz et al. [2007] reported ...

Global climate model outputs involve uncertainties in prediction, which could be reduced by identifying agreements between the output results of different models, covering all assumptions included in each. Fusarium oxysporum f.sp. is an invasive pathogen that poses risk to date palm cultivation, among other crops. Therefore, in this study, the future distribution of invasive Fusarium oxysporum ...

Regional and local climate extremes, and their impacts, result from the multifaceted interplay between large-scale climate forcing, local environmental factors (physiography), and societal vulnerability. In this paper, we review historical and projected changes in temperature and precipitation extremes in the United States, with a focus on strengths and weaknesses of (1) commonly used definitio...

[1] We quantify the vertical velocity and upward mass flux in the tropical lower stratosphere on the basis of accurate radiative heating rate calculations using 8-year Southern Hemisphere Additional Ozonesondes balloon-borne measurements of temperature and ozone and cryogenic frost-point hygrometer measured water vapor in the tropics (15 S—10 N). The impact of tropospheric clouds on the stratos...

Global surface temperature records (e.g. HadCRUT4) since 1850 are characterized by climatic oscillations synchronous with specific solar, planetary and lunar harmonics superimposed on a background warming modulation. The latter is related to a long millennial solar oscillation and to changes in the chemical composition of the atmosphere (e.g. aerosol and greenhouse gases). However, current gene...
