Endopleura uchi (syn. Sacoglottis uchi) | Space for life

Antimicrobial, cytotoxic and antioxidant activities and determination of the total tannin content of bark extracts Endopleura uchi. Endopleura uchi is a typical Amazonian tree and its bark is popularly employed in the preparation of teas against myomas, arthritis, influenza, diarrhea and cancer. In this study, the antioxidant activity, cytotoxicity and antimicrobial activity of five different extracts of the barkselected by their total tannin content, were assessed.

The potential antioxidant activity of the extracts was determined by 2. Cytotoxicity analysis in mammalian cells indicated that all the tested extracts exhibited IC 50 values higher than the highest concentration used, showing that they do not present a risk when consumed under these conditions.

Extract tested against five bacterial strains and one yeast strain did not show satisfactory growth inhibitory activity, and even the extracts that showed some antimicrobial activity were not effective at any dilution to determine the minimum inhibitory concentration.

The results may serve as a reference for subsequent works, since such reference values described in the literature for the bark of E. Cytotoxicity analysis in mammalian cells indicated that all the tested extracts exhibited IC50 values higher than the highest concentration used, showing that they do not present a risk when consumed under these conditions.

Japanese nursing students’ sense of belonging: A story of Uchi insider endopleyra Soto outsider. Clinical placement experiences are the cornerstone of nursing education and a endopleuta of literature indicates that belongingness is fundamental to students’ learning when undertaking placements. However, little is known about Japanese nursing students’ sense of belonging and how it is influenced by their cultural values. The aim of this paper is to profile a study that: A mixed methods design was used with quantitative data collected using the Belongingness Scale-Clinical Placement Experience and qualitative data collected using semi-structured interviews.

Ninety-two third and fourth year students from a large regional university in Japan completed the questionnaire; of these six also participated in interviews. The results identified similarities and differences between this and other studies of belongingness. Supportive and welcoming clinical environments facilitated participants’ belongingness and motivation to learn.

However, the belongingness scores ucni this sample were lower than those in all other studies. This may be explained, in part, by the Japanese cultural values of ” Uchi insider and Soto” outsiderwhich pervaded the participants’ placement experiences and led to feelings of exclusion and alienation. Bark And Its Possible Uses. What to do with bark is a major question facing the uci conversion industries.

Optimum utilization ensopleura bark residues demands appreciation of the complexity of bark and the extreme variation in chemical and physical properties between barks of different wood species. This report discusses bark structure, past and present utilization, and methods of upgrading bark both Beech bark disease causes significant mortality and defect in American beech, Fagus grandifolia Ehrh.

The disease results when barkattacked and altered by the beech scale, Cryptococcus fagisuga Lind. Loblolly pine bark flavanoids. The inner bark of Pinus taeda L. An ethyl acetate soluble polymer 0. BBD begins when bark tissues, attacked by the exotic beech scale insect, Cryptococcus fagisuga Lind. Barking is most often associated with the domestic dog Canis familiaris, but it is a common mammalian and avian vocalization.


Like any vocalization, the acoustic character of the bark is likely to be a product of adaptation as well as an expression of the signaler’s internal motivational state.

While most authors recognize that the bark is a distinct signal type, no consistent description of its acoustic definition or function is apparent. The bark exhibits considerable variability in its acoustic form and occurs in a wide range of behavioral contexts, particularly in dogs.

This has led some authors to suggest that dog barking might be a form of referential signaling, or an adaptation for heightened capability to communicate with humans.

In this paper we propose a general ‘canonical’ acoustic description of the bark. Surveying relevant literature on dogs, wild canids, other mammals and birds, we explore an alternative functional hypothesis, first suggested by [Morton, E.

On the occurrence and significance of motivation-structural rules in some bird and mammal sounds. Longleaf pine inner bark and outer bark thicknesses: Measurements of bark thickness generally ignore the fact that bark is comprised of both living inner bark phloem and essentially dead outer bark rhytidome.

Discerning between them has ramifications for the utility of bark as a byproduct of timber harvesting and its functionality on a living tree. Inner bark and outer bark thicknesses for longleaf pine Pinus Inspired by a beautiful bookmark one of the author’s students made for him as a gift, he began a lesson exploring the vibrant bark paintings popular all over Mexico. The majority of his students have Mexican ancestry, so exploring the arts of Mexico is always popular and well received.

Amate paintings can also be a great way to introduce the…. Bark factors for Douglas-fir.

Recent emphasis on the measurement of upper stem tree diameters with optical dendrometers has directed attention to procedures for converting these outside- bark diameters to inside- bark diameters. One procedure that has been used requires an assumption that the ratio of diameter inside bark to diameter outside bark henceforth called bark factor remains the same up Fire and bark beetle interactions.

Bark beetle populations are at outbreak conditions in many parts of the western United States and causing extensive tree mortality. Bark beetles interact with other disturbance agents in forest ecosystems, one of the primary being fires.

In order to implement appropriate post-fire management of fire-damaged ecosystems, we need a better understanding of Forest health and bark beetles. In recent years, bark beetles have caused significant tree mortality in the Sierra Nevada, rivaling mortality caused by wildfire in some locations.

This chapter addresses two important questions: How can managers prepare for and influence levels of bark beetle-caused tree mortality given envopleura forest conditions and future climate uncertainties?

Rapid endoppleura of inner and outer bark composition of southern yellow pine bark from industrial sources. Differences in bark chemistry between inner and outer bark are well known and may affect the suitability of various bark supplies for a particular application.

Accordingly, there is a need for quality control protocols to assess variability and predict product yields. Southern yellow pine bark samples from two industrial sources were separated into inner and outer bark Processing hardwood bark residues by screening. Most of the hardwood bark residues removed by floating-cutterhead or rosserhead debarkers can be processed into acceptable bark products by screening alone. And by prescreening bark residues, operators of bark processing plants can use smaller hammermills than otherwise are required, thus lowering investment and energy costs.

Estimating bark thicknesses of common Appalachian hardwoods. Knowing the thickness of bark along the stem of a tree is critical to accurately estimate residue and, more importantly, estimate the volume of solid wood available.

Determining the volume or weight endoppeura bark for a log is important because bark and wood mass are typically separated while processing logs, and accurate determination of volume is problematic. Cork Containing Barks – a review. Tree barks are among the less studied forest products notwithstanding their relevant physiological and protective role in tree functioning.

The large diversity in structure and chemical composition of barks makes them a particularly interesting potential source of chemicals and bio-products, at present valued in the context of biorefineries. One of the valuable components of barks is cork phellem in anatomy due to a rather unique set of properties and composition. Cork from the cork oak Quercus suber has been extensively studied, mostly because of its economic importance and worldwide utilization of cork products.

However, several other species have barks with substantial cork amounts that may constitute additional resources for cork-based bioproducts. This paper makes a review of the tree species that have barks with significant proportion of cork and on the available information regarding their bark structural and chemical characterization. A general integrative appraisal of the formation and types of barks and of cork development is also given.

The knowledge gaps and the potential interesting research lines are identified and discussed, as well as the utilization perspectives. Steaming Chips Facilitates Bark Removal. Whole tree chipping is a productive and economical harvesting system. The resultant product, however, is barky chips. THis paper outlines a promising method for removing the bark particles from whole tree chips.

Bark structure of southern upland oaks. Bark structure of eleven oak species commonly found on southern pine sites was examined and described. In inner bark phloemgroups of endoplfura lignified fibers and sclereids are interspersed among thin-walled cellulosic elements parenchyma, sieve tube members, and endopleufa cells.

These fibers and sclereids greatly influence the bark ‘s density, hardness, Power mulchers can apply hardwood bark mulch. Two makes of power mulchers were evaluated for their ability to apply raw or processed hardwood bark mulch for use in revegetating disturbed soils. Tests were made to determine endoplrura uniformity of bark coverage and distance to which coverage was obtained. Moisture content and particle-size distribution of the barks used were also tested to determine ichi or not these Estimating sugar maple bark thickness and volume.

Sugar maple bark thickness and volume were estimated using first a published method, then equations developed by the authors. Both methods gave estimates that compared closely with measured values. Information is also presented on variation in bark thickness and on weight and volume of bark as a percentage of total merchantable stem envopleura and volume. Segregating wood and bark chips by photosorting. Spectral transmittance measurements on aspen, endoplwura maple, and loblolly pine wood and bark chips resulted in peak wood-to- bark transmission ratio ranges from 10 to Predation and bark beetle dynamics.

Bark beetle populations may undergo dramatic fluctuations and are often important pests in coniferous forests. Their dynamics are thought to be primarily driven by factors affecting the resistance of the host tree to attack, i.

I present behavioral experiments that suggest that Tree physiology and bark beetles. Irruptive bark beetles usually co-occur with their co-evolved tree hosts at very low endemic population densities. However, recent droughts and higher temperatures have promoted widespread tree mortality with consequences for forest carbon, fire and ecosystem services Kurz et enopleura.
