a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...
Phytolacca octandra is a perennial usually about 1m high herb, dense and erect in full sun. As only few reports were available on the studies bioactive compounds various activities octandra, present study focuses bio active attributed to antibacterial activity plant extracts by Gas Chromatography – Mass Spectrometry (GCMS) molecular docking methods. Antibacterial of showed maximum inhibitory zo...
Acute toxicity studies, physicochemical and GC/MS analyses of Monodora myristica (Gaertn.) Dunal oil
Background: The seeds of Monodora myristica, a tropical plant belonging to the family Annonaceae, are widely used as condiments in preparation number African delicacies, impart or enhance flavour. Their use is largely due volatile and fixed oils contained nuts.Objective: To screen for acute toxicity (LD50) profile, determine physicochemical properties, well carry out GC-MS analysis seed oil myr...
ABSTRACT The objective of this work was to determine the composition and evaluate in vitro vivo effects essential oils (Lippia sidoides Cham., Ocimum gratissimum L., Cymbopogon citratus Stapf., selloi Benth., Citrus sinensis micranthum Willd., sp., Piper aduncum L.) on control Fusarium rot melon fruits, caused by fungus pallidoroseum. were obtained hydrodistillation their chemical determined GC...
Global climate models (GCMs) are important tools for addressing climate change questions at a global scale. Recent research has attempted to combine outputs from multiple GCMs to quantify uncertainty in regional climate change, which may ultimately inform regional stakeholders and policy-makers. Using a case study, we illustrate a potential path toward improvement in an existing Bayesian formul...
Para nitroaniline (p-Nitroaniline) is an organic compound, used as an intermediate in the synthesis of pharmaceuticals drugs, gasoline and dyes. The present study was attempted to investigate the influence of biofield treatment on p-nitroaniline. The study was performed in two groups i.e., control and treatment. The treatment group was subjected to Mr. Trivedi’s biofield treatment. The control ...
Towards a better representation of the solar cycle in general circulation models K. M. Nissen, K. Matthes, U. Langematz, and B. Mayer Institut für Meteorologie, Freie Universität Berlin, Carl-Heinrich-Becker-Weg 6–10, 12165 Berlin, Germany National Center for Atmospheric Research, 3450 Mitchell Lane, Boulder, CO 80301, USA Institut für Physik der Atmosphäre, Deutsches Zentrum für Luftund Raumfa...
The aim of this study is to evaluate the bioactive compounds in the ethanolic leaf extract of Azima tetracantha by using Gas chromatographyMass Spectrometry (GCMS). Azima tetracantha leaves were collected from Ariyalur District, Tamil Nadu. The dried leaf powder was extracted with the solvent ethanol by using Soxhlet apparatus. One microlitre of the extract was subjected for analysis by GCMS to...
Climate change in Northwest China could lead to the change of the hydrological cycle and water resources. This paper assessed the influence of climate change on runoff in the Manas River basin as follows. First, the temporal trends and abrupt change points of runoff, precipitation, and mean, lowest and highest temperature in yearly scale during the period of 1961–2015 were analyzed using the Ma...
