Cedar wood oil is ranked the tenth essential oil in the world, it can be obtained from fir wood waste, and high added value Cedar series perfumes are obtained from Cedar wood oil by chemical processing. Their aroma is very unique and cannot be replaced. At present, the cedar wood resources are dwindling; a serious influence had taken place in the flavor and fragrance industry. Study found that ...

An understanding of the interactions between climate change and forest structure on tree growth are needed for decision making in forest conservation and management. In this paper, we investigated the relative contribution of tree features and stand structure on Atlas cedar (Cedrus atlantica) radial growth in forests that have experienced heavy grazing and logging in the past. Dendrochronologic...

Components extracted from cedar timber have been reported to have stress-reducing effects in humans. If the positive effects of cedar timber in indoor environments are scientifically proven, an indoor environment that utilizes cedar timber may contribute to the improvement or promotion of well-being in humans. In this study, we evaluated the effects of inhaling emissions of volatile constituent...

In this study antifungal activities of essential oils from different tissues of Japanese cedar (Cryptomeria japonica D. Don) against four wood decay fungi and six tree pathogenic fungi were investigated. In addition, the yields of essential oils obtained by water distillation were compared and their constituents determined by GC-MS analyses. The yield of essential oils from four tissues of Japa...

A quartz crystal oscillator can be thought ofas a resonator connected across an amplifier considered asa nonlinear dipole the impedance of which depends on theamplitude of the current that flows through it. The non-linear amplifier resistance and reactance are obtained byusing a time domain electrical simulator like SPICE (Simu-lation Program with Integrated Circuit Emph...

Identification of widespread species collected from islands can be challenging due to the potential for local ecological and phenotypic divergence in isolated populations. We sought to determine how many species of the spruce budworm (Choristoneura fumiferana) complex reside in Cypress Hills, an isolated remnant coniferous forest in western Canada. We integrated data on behavior, ecology, morph...

Cedar waxwings (Bombycilla cedrorum) feed predominantly on fruits that are rich in simple sugars and low in nitrogen, supplementing this diet with arthropod prey during the summer months as well as flowers and tree sap in springtime. In contrast, thrushes feed extensively on fatty, protein-rich invertebrate prey, supplemented with sugary and lipid-rich fruits. Simple sugars and fats are digeste...

This paper reports on the status of the Fortran translator for the Cedar computer at the end of March, 1991. A brief description of the Cedar Fortran language is followed by a discussion of the fortran77 to Cedar Fortran parallelizer that describes the techniques currently being implemented. A collection of experiments illustrate the e ectiveness of the current implementation, and point toward ...
