Palo santo — the aromatic wood that has been used for traditional healing and in spiritual ceremonies in indigenous and mestizo Latin American cultures for centuries — has seen a growth in commercial popularity alongside concerns about its conservation status. Some even claim there are only trees left. To get palo santo of the best quality, the wood must be harvested in a certain way. Watch out for synthetic palo santo, where chemicals are used to produce the signature palo santo scent.

Triterpenos aislados de corteza de Bursera graveolens Burseraceae y su actividad biologica. Directory of Open Access Journals Sweden. Phytochemical investigation of the bark of Bursera graveolens Burseraceae yielded three tetracyclic triterpene acids that have oxygenation in C-3, carboxylic acid in C and unsaturation in C and have been identified as 3-oxotirucalla-8,dienoic acid b-elemonic acid, 3a-hydroxytirucalla-8,dienoic acid a-elemolic acid and 3a-hydroxytirucalla-7,dienoic acid.
This is the first report of the isolated compounds in Bursera graveolens and they have a very important chemotaxonomic significance within the Burseraceae family and related families from the order Rutales.
Agrochemical characterization of vermicomposts produced from residues of Palo Santo Bursera graveolens essential oil extraction. Fruits of Palo Santo Bursera graveolens are used for essential oil extraction.
Recent developments in Ecuadorian policies to foster environmentally friendly agroforestry and industrial practices have led to widespread interest in reusing the waste. This study evaluated the application of four vermicomposts VMs , which are produced from the waste of the Palo Santo fruit distillation in combination with other raw materials kitchen leftovers, pig manure, goat manure, and King Grass , for agrochemical use and for carbon C and nitrogen N decomposition in two soils with different textures.
The results showed that the vermicompost mixtures VMM were valuable for agricultural utilisation, because total N min. In addition, N availability increased for both soil types after the application of the VMM. In contrast, N became immobile during decomposition if the VM of the pure waste was added.
This likely occurred because of the relatively low total N 1. However, the comparatively low C decomposition of this VM type makes its application highly recommendable as a strategy to increase the levels of organic matter and C, as well as for soil reclamation.
Overall, these results suggest that the residues of the Palo Santo essential oil extraction are a potential source for vermicompost production and sustainable agriculture.
All rights reserved. Machaerium Capote Triana. Full Text Available El nombre Muchaerium. Brasilica, vol. Triana is a single-string spacecraft to be placed in a halo orbit about the sun-earth Ll Lagrangian point. The ACS Safehold design features a gyroless sun-pointing control scheme using only sun sensors and wheels. With this minimum hardware approach, Safehold increases mission reliability in the event of a gyroscope anomaly. In place of the gyroscope rate measurements, Triana Safehold uses wheel tachometers to help provide a scaled estimation of the spacecraft body rate about the sun vector.
Since Triana nominally performs momentum management every three months, its accumulated system momentum can reach a significant fraction of the wheel capacity.
It is therefore a requirement for Safehold to maintain a sun-pointing attitude even when the spacecraft system momentum is reasonably large. The tachometer sun-line rate estimation enables the controller to bring the spacecraft close to its desired sun-pointing attitude even with reasonably high system momentum and wheel drags.
This paper presents the design rationale behind this gyroless controller, stability analysis, and some time-domain simulation results showing performances with various initial conditions. Finally, suggestions for future improvements are briefly discussed. Conclusion: The aqueous extract of A.

A control strategy for Smart Grids. Forecasting, planning and real-time control. Increasing demand, extra fluctuation and a large share of distributed electricity generation will put more stress on the electricity supply chain. Therefore, changes are required in the supply chain to maintain a properly functioning, stable and affordable grid. Currently the supply chain is completely driven by demand by constantly adapting the production to the demand.
The exploitation of flexibility on the demand side of the supply chain allows for a more efficient and sustainable electricity production.
Techniques like controllable distributed generation, distributed storage, and smart appliances can introduce this required flexibility. To exploit the new flexibility, the grid has to become more intelligent, i. In the first step of TRIANA , the forecasting step, the scheduling freedom flexibility of a device is determined for each individual device by a local controller. In the second step, a central planner tries to exploit the freedom of the devices determined in the first step for his objective.
The last step of TRIANA is the real-time control step performed by the local controller achieving the planning in the best possible way. In order to analyze the impact of control methodologies for Smart Grid, a simulator based on an energy model has been built. The basic elements of the model are individual devices and between devices energy streams are defined. The energy streams are connected via so called pools, which represent the physical connections between the devices.
To study the effectiveness of the control methodology and study the most economic use of the flexibility of devices, multiple scenarios have been simulated. Simulations show that TRIANA can optimize the energy flows and can control the operation of the domestic devices in an economic manner without discomfort for the residents.

Ozone injury to celery. Ozone is the principal air pollutant damaging crops in Connecticut. Ozone injury in Connecticut has been found on a number of crops including tobacco, tomatoes, potatoes, spinach, alfalfa, and cereals. This is the first report of ozone damage to celery Apium graveolens var. On July 7, , celery plants with badly damaged older leaves were found in a commercial garden near Shelton, Connecticut.
The injured leaves showed chlorotic and necrotic interveinal areas on their upper surfaces. These areas were slightly depressed. Cross sections of the lesions revealed that the palisade cells were most severely injured. Spinach and carrots growing near the celery showed typical symptoms of ozone damage.
To substantiate the diagnosis, young celery plants were exposed to 0. Five days later, these plants developed symptoms indentical to those found on celery in the field.
Is Palo Santo Endangered?
Without questuion, my favorite trees here on the coast are ceibos and palosanto. Straight from a Tim Burton film or a page out of Dr. Seuss, these large trees feature bright green bulbous trunks, prominent buttresses and a disarray of heavy limbs extending in all directions. Historically, the super soft kapok fibers were collected and used to fill pillows, mattresses, stuffed dolls, etc. Today, there are still a couple of small communities in Manabi that collect the cotton to make pillows and mattresses for sale. Here in the dry coastal forests, ceibos spend much of the year without any leaves , a condition called drought-deciduousness.
Palo Santo – Bursera graveolens: The Holy Oil
It is widely used in ritual purification and as folk medicine for stomach ache, as a sudorific , and as liniment for rheumatism. Illegal logging is a regular occurrence in northwestern Peru due to high demand. Palo santo is used for crafting objects and to produce burning sticks and incense. Production of essential oil is attracting most of the modern interest.
My project tests the hypothesis that the palo santo tree Bursera graveolens consists of multiple, distinct species. I will also quantify genetic diversity in palo santo populations to aid ongoing reforestation efforts. To test my hypothesis and compare genetic diversity levels, I will sequence DNA from palo santo trees. My project will identify new, possibly endangered, species and help to restore declining palo santo populations and its critically endangered tropical dry forest habitat.
