The Tropical Rainfall Measuring Mission (TRMM)'s 'day-1' combined radar/radiometer algorithm uses a rain-profiling approach which gives as much importance to the measurements of TRMM satellite's precipitation radar (PR) and microwave imager (TMI) their respective intrinsic ambiguities warrant, avoids any ad hoc shortcuts that might introduce large biases in rain estimates, yet is simple enough be operational when launched 1997. based on idea estimating profile using reflectivities, while...

The SIR-C/X-SAR imaging radar took its first flight on the Space Shuttle Endeavour in April 1994 and flew for a second time October 1994. This multifrequency has fully polarimetric capability at L- C-band, single polarization X-band (X-SAR). missions were designated Radar Laboratory-1 (SRL-1) -2 (SRL-2). Calibration of C-band data all different modes SIR-C offers is an especially complicated problem. solution involves extensive analysis pre-flight test to come up with model system, in-flight...

Bacteria exhibiting beneficial traits like increasing the bioavailability of essential nutrients and modulating hormone levels in plants are known as plant growth promoting (PGP) bacteria. The occurrence this specific group bacteria endophytic environment may reflect decisive role they play a particular condition. This study aimed to determine taxonomical diversity culturable bacterial endophytes, isolated vegetative stage passionflower ( Passiflora incarnata ), assess its potential promote...

This paper addresses the critical challenge of liquid leaks in oil and gas industry by leveraging advanced computer vision deep learning methodologies. The objective is to develop practical models for detecting underwater objects with low image quality adverse conditions. We train test CNN detectors using Facebook's Detectron2 Faster R-CNN. model was evaluated on a custom dataset spill videos, focusing detection accuracy processing speed. results demonstrated that even images smoke sky as...

In this study, we examined the chromosome number and some morphological features of strains Stevia rebaudiana. The chromosomes were analyzed during mitosis diakinesis, tetrad normality pollen viability also assessed. addition, stomata measured plant studied morphometrically. All had 2n = 22, except for two, which 33 44. Pairing at diakinesis was n 11II all diploid strains, whereas triploid tetraploid 11III 11IV, respectively. Triploid plants a lower rate than diploids. inviable pollen. Thus,...

Volatile oils from leaves and flowers of Aloysia gratissima were investigated for their chemical composition antimicrobial activity against the bacteria Bacilus subtilis, Staphylococcus aureus, Salmonella choleraesuis, Pseudomonas aeruginosa, Streptococcus pneumoniae Candida albicans yeast. The minimum inhibitory concentrations (MIC) determined by micro-dilution method, while was GC-MS (gas chromatography mass spectrometry). fresh inflorescence subjected to hydrodistillation 120 min using a...

Leaks from accidents or damage to pipelines that transport liquid petroleum hydrocarbons (PHC) such as gasoline and diesel are harmful the environment well human health, may be hard detect by inspection mechanisms alone when they occur in small volumes persistently. In present study, we aim identify spectral anomalies two plant species (Brachiaria brizantha Neonotonia wightii) linked contamination effects at different developmental phases of these plants. To do so, used spectroscopy remote...

In order to evaluate the geographic mosaic theory of coevolution, it is crucial investigate geographical variation on outcome ecological interactions and functional traits which dictate these outcomes. Plant populations are attacked by specialist non-specialist herbivores may have different types chemical biotic defences. We investigated seasonal in interaction between plant Crotalaria pallida its two major (the Utetheisa ornatrix Etiella zinckenella). first showed that attack a defence vary...

Abstract Stevia rebaudiana Bertoni, Asteraceae, is an herbaceous perennial plant native to Paraguay. This species considered since ancient times a medicinal with important bioactive compounds and pharmacologic food properties, namely diterpenes glycosides. The high natural sweetener potential stevioside rebaudioside A produced by S. plants are suitable sucrose substitutes, their obtention influenced environmental, phytosociological, genetic factors. plants’ profile sweet depiction needed for...

Soil organic carbon (SOC) is a key property of soil quality in arable soils and can play central role the voluntary credit market by improving health, future food security mitigating against climate change. The adoption regenerative agricultural practices are considered one solution to achieve increases SOC sequestration rates. However, spatiotemporal dynamics mean changes attributed management often difficult detect across different spatial scales over short temporal periods. Thus, rapid,...

The SIR-C/X-SAR imaging radar took its first flight on the Space Shuttle Endeavour in April 1994. This multi-frequency has fully polarimetric capability- at L- and C-band, a single polarization X-band (X-SAR). Calibration of C-band data for all different modes SIR-C offers is an especially complicated problem. solution involves extensive analysis pre-flight test to come up with model system, in-flight determine actual antenna pattern gains system during operation, from over ten calibration...

The Alaska SAR Facility has been receiving and processing data from the J-ERS-1 satellite since Spring 1992. Corner reflectors have set up for calibration at a site near Delta Junction, in central Alaska. Image quality analysis results Junction others are presented. impact of 3-bit analog-to-digital converter automatic stepping gain as function range radar receiver on performance assessed. Preliminary observations that average signal-to-noise ratio is generally fairly low, 5-6dB. Azimuth...

Cecropia glaziovii is a tree with used in Brazilian popular medicine. Methods allowing the clonal propagation of this species are great interest for superior genotype multiplication and perpetuation. For reason, we examined effect different culture media types explants on adventitious shoot regeneration from callus buds C. glaziovii. Leaves, petioles stipules obtained aseptically grown seedlings or pre-sterilized plants were to initiate cultures. Adventitious was achieved when apical...

A joint calibration experiment between the synthetic aperture radars (SAR) onboard NASA/JPL's AIRSAR and Japan's NASDA J-ERS-1 satellite was performed by cotemporally imaging Manu National Park in Peru on June 7, 1993. The data from both instruments were subsequently processed calibrated at their respective institutions. In situ site consisting of ground aerial photographs, GPS coordinates, dielectric measurements, ecological characterization, rainforest structural parameters, vegetation...

A especie Jatropha curcas L. (Euphorbiaceae), podera se tornar uma opcao agricola para o Brasil, pois alem de suas qualidades, que permitem seu oleo seja transformado em diesel viavel a obtencao do biodiesel, ela e nativa resistente seca. E selvagem carece estudos fitotecnicos. Nosso objetivo foi realizar ensaios melhoramento fitotecnia. Para trabalho melhoramento, individuos 7 populacoes estao sendo selecionados. Utilizamos numero frutos produzidos quantidade total produzido por safra como...
