What is the ethical-spiritual and universal world formula, the Grand Unifying Theory? Does ancient Indian knowledge lead us to an intercultural world peace formula? Does it have an impact on physics, metaphysics, biology and our absorption of spiritual healing power, etc.? 11/27/24 Chris K. Früh – Intercultural-philosophy-institute.ch / guna.ch / emailATyogapsychologie.ch (Summary of the Peace Manifesto on one sheet of paper, printed on both sides. The page numbers refer to the free downloadable ebook at: guna.ch/yoga.pdf – Sources for the Gunas and synonyms; e.g. Bhagavad Gita 2.45, chapters 14-18, Bhagavad Purana 11.15.28, 11.25.2–5, 12.8.46) First of all: What is the physical, spiritual and universal world formula, this “Grand Unifying Theory”? The “Gunas”, to which the Bhagavad Gita (p. 3) devotes over three chapters, have an impact on metaphysics, on consciousness, its respective forms of life, but also on physics, as time factors of ● emergence, creation (Raja), ● existence, preservation maintenance (Sattva) and ● decay, destruction (Tama, p. VIII). Let us begin with a simple, everyday example: our teeth and, in this comparison, first look at the synonyms for the Sanskrit umbrella term Sattva (from Sat = being): ● Existence / preservation / maintenance: In order to preserve our teeth, we must clean them, then they are beautiful, healthy, and attractive, and we enjoy them and also become fearless of the dentist. But we must first know that and also have the wisdom and our mindfulness and self-control to carry out this cleaning and care rhythmically and regularly. It is the same in music; Beauty is tactful and a regular oil change also keeps the car engine running (for further synonyms see p. 31 ff and 64 ff). ● Decay and destruction: But if we come home every day intoxicated on drugs (or drunk), then we forget to brush our teeth and soon our teeth are dirty, sick, disgusting, rotten; and we suffer and are afraid of the dentist. These are synonyms for Tama, the thought transmitter that holds us down and wants to prevent us from ethical-spiritual evolution. ● Creation: In order for the dentist to “create” new teeth, we first have to “acquire” the money, go to work and/or exploit something (raw materials etc.): These are synonyms for Raja, the marginal intermediate stage (p. 63) of the working person, because: “People have to eat (and work :-)!” (p. 65). The knowledge of this natural and timeless scale of ethics, which is described, for example, in the millennia-old Bhagavad Gita, is not outdated, but rather timeless. It is timeless and old and yet always relevant – and especially today of the utmost urgency for all of us, for our spiritual evolution: This trinitarian world view of the three Gunas is illustrated with further examples: Just as a three-legged transistor controls the dual/digital computer world, the three Gunas are now above material duality. This means that what is really good or goodness can only be precisely defined in this trinity (p. 31)! Let us try to illustrate this graphically, because these Gunas are always mixed in different ways in our changing, temporary world: They are the umbrella terms for all characteristics and can thus be compared to the primary colors or color diodes in a screen, which can display an infinite number of beautiful or ugly images; ● Red for Raja: origin, creation, exploitative passion, ● Yellow for Sattva: existence, preservation and healing, goodness, happiness, joy, peace, health and wisdom, etc. and ● Blue for Tama: decay and destruction and degenerating ignorance (on the graphic below, and on the website Yogapsychologie.ch, or in the e-book on Guna.ch/yoga.pdf) The knowledge of this intercultural-natural scale of ethics, which is described in the millennia-old Bhagavad Gita (S V ff), is not outdated, but rather it is timeless and of utmost necessity: ● 1.: We, the conditioned souls, are ourselves the cause of our karmic radius of freedom and live here as if in an amusement park, in a kind of virtual reality for training and testing our free will (within the respective karmic radius of freedom) in (we hope) the direction of our ethical evolution, in the direction of non-violence and Prema, the all-encompassing love. Our intercultural world peace formula of the Grand Unifying “Theory” for the material universe is thus: S = Vs + R + T + Z, or: Vs = S - R - T - Z (Vs = Visuddha-Sattva, S = souls, R = Raja-Guna, T = Tama-Guna, Z = time, as the constantly remixing element of these Gunas).

● 2.: In the liberated state of the souls, Visuddha Sattva is S = Vs, since the unmixed pure form of Sattva is the eternal spiritual good (NityaSattva, Gita 2.45) that is worth striving for. Sattva has its root in Sat = eternal. Therefore, the word Guna (mixture) is omitted from the word Visuddha Sattva. The Visuddha-Sattva is now ”the wood we are made of” and our eternal spiritual nature, and so is pure all-encompassing love Prema, our actual, eternal, real uncovered nature. ● 3. When pure, spiritual love (Nitya-Prema-Sattva) comes into contact with exploitative passion (Raja-Guna), it turns into lust, and when it comes into contact with destructive ignorance (Tama- Guna), it turns into hatred. The exploitative passion and the destructive ignorance are only temporary, material conditions that only temporarily cover the living being, the eternal spiritual souls. Even if, from our materially conditioned perspective, this can last a very long time. From the perspective of the liberated living being, all these quartillion+ lives, in all the possible life forms, are only an infinitely short period of time. ● 4. On our liberated plane of pure, unmixed Sattva, after having left the gross and subtle bodies, one has only a spiritual body of Visuddha Sattva, selfless and all-embracing love, without the slightest trace of exploitative passion and destructive ignorance. The word body, however, is poorly chosen in this context, for one must understand that the spiritual soul is no different from the spiritual body. The yogi, the true artist and the true philosopher are all searching for one and the same substance; the pure form of Visuddha-Sattva, because it is the “place” or state where the three aspects of cultural life meet in their pure form: 1. Truth, 2. Enjoyment and 3. Spirituality (Tattva, Rasa, Yoga): Tattva = Truth, Wisdom, Science, Philosophy etc. and Rasa = Enjoyment, Taste, Art, Music, Poetry etc. Yoga = Connection, Spirituality, Healing, Religion etc. (Sanskrit: Yoga = yoke, connecting, Latin: Religare = reconnecting). The Self-realization and highest stage of perfection is now Visuddha- Sattva, which is achieved when the Yogi has understood and realized the principle of Rasa-Tattva: an omnipresent Truth, unmixed Beauty and all-embracing Love, which is only possible in free will. ● 5. The universal ethical scale of the three Gunas is of divine origin as the world peace formula and also the “creative design” of a world joy formula in the origin, nature, meaning, purpose and goal of the universe. NityaSattva is the characteristic of the personal aspect of the absolute truth (p. 11). The first verse of Sri Isopanishad is in this sense: “Om purnam adah purnam...: If the Absolute is to be absolute, then it must contain all that is found in its parts, i.e. it must contain a holistic, healing personal and loving aspect in addition to its impersonal aspect, otherwise we would have something more than the Absolute. The spiritual joy and the eternal, spiritual sphere are attained through the pure virtue of Nitya-Vishudda-Sattva. ● 6. Pure Sattva, i.e. Prema, all-embracing love and the strict avoidance of unnecessary violence, is the definition and ethical development of the true culture of humanity. And this brings us to our formulas for peace found in the Sanskrit texts. Gandhi was inspired, for example, by the Bhagavad Gita with its formula for peace in verse 2.45: “The Vedas (ancient Indian scriptures) mainly deal with the manifestations of the material nature of the three Gunas that occasionally mix (p. 32). Transcend all these illusory mixtures and be free from the material dualities and manifestations! Do not worry about illusory security and be anchored in the true self, in the NityaSattva (eternal, all-good Sattva healing current) of the “Atmavan”, the individual soul!” This formula is further explained in the Bhagavad Purana 12.8.46: “The place of fearlessness and eternal existence is the characteristic and direct, liberating and healing spiritual energy (“Sattvam”) of the all-good personal aspect of the Absolute. Exploitative passion (Raja) and destructive, degenerating ignorance (Tama) are only His indirect material energies, which exist only in the material (= transitory) and illusory world; we never consider these as His personal energy and divine attribute!” And we have an explanation of this verse from Jiva Goswami, an Indian philosopher 1513 –1598, in his Sat Sandarba in Bhakti Sandarba Anuccheda 103/38, p. 73): “Sattva-Guna is always a little mixed with Raja-Guna and Tama-Guna in the transitory and illusory material world. If we let our emotional body (the Citta, p. 67) be cleansed of the shell of the materially mixed and impure Sattva-Guna with the pure, eternal and divine healing current, then we will soon be on our real, genuine, spiritual and liberating, i.e. healthy, level of NityaSattva (the eternal goodness of the soul, as in Bhagavad Gita 2.45).

Is there any data in the current literature (from the last 10 years) that reports how much biomass is stored in the wood of the cacao tree? Is there any estimate of how many cubic meters of wood a cacao plant produces? I have been searching the literature but have not found anything yet. This information is crucial to determine how much biomass a cacao plantation yields at the end of its cycle.

hii

anyone have idea about Lab scale Activated carbon process. can you suggest any method for prepared to activated carbon from wood base material at lab scale.

Dear all,

Does anybody have a pdf of this paper?

Hello,

I have a problem in which a steel nail is 'embedded' in a wood piece. The head of the nail is in contact with a steel bracket. As I apply cyclic load on the vertical wood 'wall', the bracket moves up and pulls the nails of the horizontal wood part, which gets pulled out of the wood (see Image). However, as the bracket unloads (and consequently so does the nail) the cohesive interaction that I defined between the nail and the wood simply unload to zero as well. This causes the nails to follow the bracket back into original position. I wanted the nail to retain the maximum displacement imposed by the contact with the bracket before the bracket starts to unload.

Looking at the ABAQUS documentation, it says the when using cohesive behavior, it will always unload to the initial position (see image of the cohesive material model used in ABAQUS). How can I overcome this? It can be either using contact pairs or any other strategy in ABAQUS (except cohesive elements, which I've tried and could not manage to work in my model).

I've already tried to use a custom defined FRIC subroutine in a tangential interaction behavior (doesn't work). I've thought about writing a custom UMAT subroutine, but ABAQUS does not allow a user-defined routine for cohesive response of contact pairs. I've tried to run an analysis with the ABAQUS default cohesive response, then get the nail deformations at peak and try to apply these as boundary conditions at the correct steps of the analysis. I also tried to use the option where ABAQUS maintains the initial position of an object during a step. However, these last two approaches seems to cause numerical instabilities in ABAQUS due to activating and deactivating boundary conditions in between steps.

I know that most wood degrading fungi have developed a certain resistance and protection mechanism against H2O2 and its radicals, but does someone know the MOST resistant fungus and maybe also the mechanisms by which it gets such a high resistance?!

This is a question that I've always had but never asked the bigger research body. For journal articles and presentations, I use PowerPoint or Canva to make specimen drawings or schematics. However, they look very amateur and not publish-worthy.

What other easy-to-use software/sites are available? I'm more so interested in drawings such as the one attached.

Thank you!

Using waste mango woods as the source, how can nanocellulose be produced from it using acid hydrolysis process

I have implemented an adsorption test of heavy metal solution using wood straw biochar(without any Acid/Alkali activation) as an adsorbent. The degassing temp was 200C for 6h. After adsorption, there is a 10-15% increase in surface area.

Kindly note that the test was repeated 2 times with the nearby same results. What could be the possible reasons for it?

Has anyone assessed the wood properties (microfibril angle, acoustic wave velocity, basic density) of Araucaria species, such as Araucaria cunninghamii (Moreton Bay pine), hoop pine, Araucaria heterophylla (Norfolk Island pine), Araucaria araucana (monkey-puzzle or pehuén), or Araucaria angustifolia (Paraná pine)? Have any wood anatomy studies been conducted on these species? Are there any studies that assess longitudinal or radial variations in wood properties for these specific Araucaria species?

Due to the rapidly increasing level of plastic waste pollution in the green transformation of the economy, plastic packaging is being replaced by packaging made from biodegradable plastic substitutes, materials of organic origin, produced from vegetable crops, or packaging made from paper, wood. Unfortunately, the production of packaging from paper and/or wood is not a pro-environmental solution either, as it generates the cutting down of trees, increases the scale of forest deforestation. On the other hand, in connection with the still increasing scale of greenhouse gas emissions, the accelerating process of global warming, the processes of forest deforestation should be replaced by the processes of aforestation of civilizationally degraded areas, post-industrial areas, areas with sterilized soil, etc. In view of the above, there is a growing need to create green technologies and material eco-innovations, where it would be possible to create and implement paper production technologies from other forms of flora, plants other than trees, e.g. from shrubs, grasses, perennials, fallen leaves, straw, waste from crop production and/or lumber waste.

In view of the above, I address the following question to the esteemed community of scientists and researchers:

And what is your opinion on this topic?

I'm trying to model a wood-steel connection in shear in ABAQUS CAE, but I'm having some troubles with convergence and overlapping in the model.

In one model ('With-interaction') I apply an interaction (surface-to-surface) between the steel plate and wood and another one between the steel plate and the base of the connectors' head, but the model do not converge since the begining.

In the other model ('No interaction') I remove such interaction, the model still perform some steps but there is overlapping of the steel plate on the wood.

Does any one had experienced such type of problem? What maybe the causes? Files and print screens are in attachment.

Best regards

If so, do you have any idea on the relative abundances of both types of fibers?

Hello everyone,

I am currently working on my bachelor thesis and struggle with a concept.

The goal of the thesis is to analyse the potential benefits and risks for a data exchange Platform for SMEs in the wood supply chain.

My strategy way to conduct a „literature review“ to find potential use cases in both the wood industry but also potential applications from other sectors that can be adopted.

Additionally, I would like to conduct Semi-structured Interviews with industry experts to validate/invalidate the findings and extend the knowledge pool.

My question now is, what kind of methodology is that? I often read that a literature review is not a methodology but what else is it called.

I would appreciate any advice on how such research Design is called or can be adjusted to fit the project goals.

Thank you very much in advance.

Twenty years ago I operated a biofilter for wastewater treatment. I set layers like this (Pic_004_b):

Superficial layer: earth with live earthworm (Eisenia foetida).

Layer 1: sawdust

Layer 2: gravel diam 3/8"

Layer 3: gravel diam 1/2"

The remove BOD5 (biochemical oxygen demand in five days) efficiency was 79.6 %, but chemical oxygen demand (COD) for both influent and effluent was the same.

Then I suspected was lignin from wood. Can someone confirm o reject it? and why?

In most African countries, a large number of people rely on charcoal, which is made by burning wood. We are all aware of the climate crisis, and the endless efforts being made to reduce deforestation, as well to reduce the carbon dioxide emissions across the globe. Many countries in Africa have been severely affected by the crisis in terms of food shortage, floods, disease and so on. If African countries are to make a move of banning the production and usage of charcoal( eg in some parts of Uganda), what else can they use? What will this mean for the numerous people who relied on coal, and for the economies?

Is wood vinegar potentially toxic to insects and bees?

Is there any research or work done on the use of transparent wood in medical equipment such as disposable syringes, gloves or medical marks? Does anybody have any idea?

As we know, trees, forests, especially old, natural forests, primeval forests with old-growth forests without human interference, without the influence of civilization, are the refuge of the greatest resources of biodiversity of natural ecosystems. Besides, forests play a particularly important role in the issue of slowing down the human-induced global warming process, which is progressing faster and faster. Forests also play a very important role in mitigating weather and climate anomalies, maintaining a mild microclimate friendly to living organisms, keeping the soil and air moist, maintaining the high level of biodiversity and soil fertility created over thousands or millions of years, and so on.

Deforestation still dominates over afforestation in many regions of the world. Forests are still being cut down and burned to acquire new areas for agricultural development, the cultivation of crops, which is usually carried out in the form of unsustainable robbery. In addition, this practice is carried out mainly in the tropics and subtropics, where after logging, forests created new arable land is quickly subject to drought and the soil becomes barren. Restoring a forest that has functioned for thousands of years or more in a specific area on the depleted soil requires huge expenditures. In addition, vegetable crops are grown on these new agricultural areas, which are either transported thousands of kilometers to other countries, which generates high greenhouse gas emissions, or are not used for human food but for livestock feed, which also generates high emissions, as industrial livestock farming is a source of high emissions of the potent greenhouse gas methane. Therefore, with a view to protecting the climate, biosphere and biodiversity of the planet's natural ecosystems, to reduce greenhouse gas emissions and counteract the ongoing process of global warming.

Various examples of reducing paper consumption and saving forests are as follows:

In some countries, the scale of printing notebooks, notebooks, books, including school books, has been reduced and students as early as elementary school write at school on tablets or laptops rather than in paper notebooks. Green economic activities involving, for example, the production of furniture from recycled materials are also emerging.

Another example is the replacement of dirty energy based on burning firewood with renewable and emission-free sources of clean energy. Unfortunately, in some countries, in order to falsify statistics on the development of renewable energy at the behest of the government, central statistical institutions, ministries and government agencies dealing with climate and environmental issues also count firewood as a renewable energy source. Such absurdities unfortunately still exist in some countries.

Another example is the use of secondary raw materials of various origins in the construction industry instead of using wood, and especially instead of newly harvested wood from companies producing building materials based on fresh, new wood raw material from a sawmill.

As of 1.8.2023, paper receipts are not printed in France to save trees. You have to ask for a printed receipt if the customer needs one.

What other examples of reducing paper consumption and saving forests are as follows?

In view of the above, I address the following question to the esteemed community of scientists and researchers:

Counting on your opinions, on getting to know your personal opinion, on a fair approach to the discussion of scientific issues, I deliberately used the phrase "in your opinion" in the question.

The above text is entirely my own work written by me on the basis of my research.

In writing this text I did not use other sources or automatic text generation systems.

Speed=Utter Energy*Velocity Equation…. Speed=F*dx,Then Speed=ma*dx,Then Speed=m*v/t*dx,Then Speed=mdx/t*v,Then Speed=Utter Energy*Velocity.S=UV..Simple Equation but my Very Favorite…And I Guess This Equation Speed=Utter Energy*Velocity Equation It Goes Everyside In Science In Universe….People-Animal-Fish Walk-Run-Planet Movement-Chemistry Atom Velocity And Everyside In Science In Universe It Goes.Here At Elements Mass And Utter Energy Comes With Mass Inside Atom Velocity When Atom Distribution And Distance comes With Time And Utter Energy Velocity Comes With Mass And Atom Distribution.

Work-Energy And Kinetic Energy Equation……Physics Books Says…..E=1/2MV2(SQUARE)……And Work=1/2MV2(SQUARE)……….But Here Acceleration And Velocity Uniform But Nothing Is Uniform In Universe…….But My Equation….

And Simply…..Kinetic Energy Or Work Or Energy Equation=F*Dx….. Then..W=ma*dx...W=m*v/t*dx….W=mvdx/t…..W=mv2(SQUARE)……….Here Dx=Distance,T=Time,V=Velocity,a=Acceleration

Work Equation= We Know W=F*Dx...Then..W=ma*dx...W=m*v/t*dx...Now....W=M*V*Dx/t..W=M* Δm (Delta Mass)/Δt (Delta Time)*dx/t...Now..W=M*V* Δm (Delta Mass)/Δt

Now...W=M*V* Δm/Δt…….W=MV Δm/ Δm/V……..W=mv2(SQUARE)……….

HERE, Δm (Delta Mass)= V× Δt……And…. Δt= Δm/V

I Guess my equation is correct cause earth physics books Says…. Kinetic Energy Equation-Energy Equation And Work Equation……Physics Books Says…..E=1/2MV2(SQUARE)……And Work=1/2MV2(SQUARE)……….But Here Acceleration And Velocity Is Uniform…..but nothing is uniform In Universe…At Our Physics Book Work-Energy-Kinetic Energy Equation=1/2 mv2square But Here Velocity And Acceleration Uniform But Nothing Is Uniform In This Universe...Atom Velocity,Air Velocity,Water Velocity,Light Velocity And Nothing Is All Time Uniform In This Universe But Our Physics Books Many Many Equations And Isac Newton Equations Depends On Uniform Velocity And Acceleration Equations.but nothing is uniform In Universe

Hi everyone, I am researching about the potential use of the liquid byproducts of the carbonization process of Gmelina aborea wood residues (i.e. wood vinegar and wood tar), as fungicides against Ceratocystis fimbriata which is causing a vascular wilt in Gmelina arborea trees.

I am conducting a in vitro experiment but I also want to do an in vivo test. I would appreciate recommendations of methods and procedures.

Thanks in advance,

Jair Granados-Chacón

I want clarification on the type of wood powder to opt for as an adsorbent for removing Copper and Lead from soil. Also which sieve size will you recommend, is 60 mesh sieve size okay?

Hello,

I have some lake sediment cores which I am planning to date using AMS radiocarbon dating and tephrochronology. Are there any recommended procedures for sampling lake sediment cores to remove terrestrial plant remains and things such as wood, charcoal, bone, etc, for radiocarbon dating?

I have come across some methods that mention placing the sediment sample in water, sieving the samples and then picking out the target items using fine forceps or a paint brush.

Any recommended papers or procedures would be welcome.

Thank you.

In our laboratory, we are looking for the application of wood anatomy as a precise and key tool for identifying not only species but also varieties within a species. Specifically, we are interested in studying the different varieties of Cocoa, Coffee, Cedrela, and Clusias.

Then, we would like to know What are the key anatomical wood features that can be used to accurately distinguish between different varieties within a species?

If you have experience in identifying species based on anatomical characteristics of the wood, we would greatly appreciate your insights and any recommendations you may have for our research. Can we consider the Pits and perforation plates as key features of wood identification?

Thank you for your time and assistance.

I am interested does anyone tried to measure tree rings from sub-fossil oak cross-sections using an image analysis technique? When working with tree-ring measuring table, I usually do the measurements when the wood is still wet. I prepare a band on surface with a razor blade and treat it with chalk. However, the taking scans is problematic because the samples usually are quite big/heavy and the preparation of entire smooth surface is too difficult. What are your thoughts or experience with such samples?

I am working right now on a paper that validates the experiment of the double shear on a wooden dowel, and I am using Abaqus for the numerical analysis of this connection. I am trying since a while to define the plasticity of wood in Abaqus, but I can not. Where can I get the values of the Plasticity of a specific type of Wood?

I can not simulate as well the failure that would happen to the connection.

It would be really helpful if anyone told me how I can overcome those two problems.

Thanks in advance

During concrete casting works in construction projects, there are several factors that affect the quality of concrete on-site, some of which are related to the supplier concrete, some of them are related to casting workers, and the other is the implementation of wood molds and reinforcing works.which the factor was critical

How we can interpret the presence of Hf peak in EDX spectra of reference birch wood ? While I have not seen this peak before in wood samples.

I m trying to estimate the concentration of lignin in rice husk. I m using TAPPI T222 method for this purpose. On treating with 72% sulphuric acid, the husk powder is still visible. Is it correct or I m missing somewhere.

Since after this water will be added and 4 hrs boiling will be done and then protocol says to filter and weigh the filtrate. Under such condition the filtrate will have husk powder as well.

Dear all, is anyone able to identify this beetle (wood devouring)? Could find many similar images, but none with a crenelated pronotum.

In advance many thanks

The wood of the endangered tree species Paubrasilia echinata (previously Caesalpinia echinata), has traditionally been used for making string instrument bows. Currently, there is a discussion about how best to conserve this species. In particular, there is an initiative to upgrade its international conservation status on CITES, which would lead restriction of Brazilwood trading . Bow makers and related industries are presently lobbying against the CITES upgrade. I find it difficult to obtain unbiased, objective information on how to best address this problem from a conservation perspective. Can anyone please comment? Many thanks,

Thomas

We are interested in view on whether the different planting patterns in softwood plantations significantly affects form and wood property variation, and studies that examined them. For example if a stand is planted at 1111 sph, does the row x column pattern have any measured effect? Do stands planted on a 3 x 3 spacing differ noticeably and consistently from stands planted at 2 x 4.5?

Do you have any recommendations for low-budget acoustic emission (AE) sensors and instrumentation for wood testing? I expect to register activities that will go up to 400 kHz.

BACKGROUNDS: As we all known, the capture of the failure and post-failure in simulation of timber structures is very important. Timber structures deveops fast up to now, simulation methods have been play ing critical roles in understanding the failure mechanics and structural behavior. With the success of simulation, i.e. getting reasonable simulation results, one can proceed the subsequent works, such as design, assessment, and strengthening, etc.

FIELDS : CLT, GLT, Ttaditional timber structures, wood-based structures, furniture structures, etc.

especially some elements needed fined simulation to reflect the whole failure process.

PROPOSE: every one can actively say anything here, from ideas to some discussions, dont just limited to the answer of my questin.

Hi!, I'm currently on a investigation project that consist in production of charcoal by slow pyrolysis of wood. As we know, the products of this process is char, syngas and tar. The thing is that we want to minimize this tar production because its complicated usage. For what we saw, the tar can be degraded to volatile non-condensable gases and avoid that liquid phase. The temperature we are modeling the process is about 400-450 ºC,. My question is: is this enough to only have coal and syngas at the end of te process?. If not, how can we avoid the tar production and only have syngas as byproduct? I hope I have explained myself well.

Thanks!

Eleven months ago I girdled 17 trees and measured the moisture content, at the place where they had been girdled, with a wood moisture meter. Typically, the moisture meter showed a reading of about 30%. Now recently I have cut down the trees and cut them into pieces, and I have measured the moisture content at the same place as before, as well as at 5, 10, and 15 meters height, both externally (cutting of the bark with a machete) as well as internally (at the place where I have cut the trees in to short pieces with a chainsaw). The weird thing is that, in spite of that the trees now are dead and very light, the readings on the moisture meter indicate the opposite, they typically are around 40%, as if the moisture content would have _increased_, something which obviously is not the case.

All this happened in western Amazonia (Ecuador) where the climate is very humid, such that I think it sounds quite normal that wood has a moisture content of 40% even in trees that have been girdled 11 months ago. But what I do not understand is why the moisture meter showed just 30% when the trees were alive and the cells must have been basically full of water.

Hello everyone,

I intend to do some investigation on applied Computer Vision on Wood Log Detection. For that I would need a proper sized Image Dataset. Ideally, this should be publicly available to give others the chance for comparison.

The only source I found on this topic was the paper "The HAWKwood Database", but the link given to the Database in [1] is offline.

Anyone knows how to get access to that - or similar - datasets?

Any help is appreciated!

Thank you very much!

Kind Regards,

Jonathan

I tried to solve this on my own, however, this is way out of my area of expertise. Can the remains of a snake become fossilized within the interior of a tree? My husband is big into woodworking and around a week ago he brought back a piece of oak that was down. It has been through a fire. On the edge of the piece of wood, there is clearly a snake. I can see what appear to be vertebrae in a section or two in the areas where the spine would be. It is absolutely stunningly beautiful. Can this happen? Does this happen? Thanks.

Fossil wood rotting fungus, spores 2-3 celled, growing in an cf. Anacardiaceae fossil wood.

Wood is a wonderful resource and we use it in almost everything. It would be fun if wood could not be seen but touched. So, could wood ever be transparent?

I have recently started a wood decay experiment in a soil medium and, only two weeks after placing the samples in the jars, an unwelcome fungus started to grow on the top of a large number of samples. I suspect that the contamination may come from the samples themselves, as there are no signs of contaminations elsewhere in the jars and the contamination was absent until the samples were placed in the jar.

While I have not chosen yet to stop the experiment, I would like to try to identify this fungus without removing the lids; it is blue-ish green in color and has a powdery appearence. It may also be resistant to heat, as it withstood autoclaving. I suspect that it might be Aspergillus flavus, but I would like your insight in case other fungi exists with a similar description.

Thank you for your help,

Hi everybody,

I want to examine the relationship of wood density with tree growth rates expressed as (i) diameter growth rates and (ii) biomass growth rates. In your opinion, what would be the best way to compare these two relationships, for example in terms of strength and/or the slope. Any advice on R packages or functions would be very valuable.

I'm looking for an answer to question:

Is there a universal method for converting and determining wood density from drilling results using a resistograph?

Tool: IML PD400

I'm doing a conservation project regarding the deacidification of PEG treated waterlogged wood.

First, I did some analysis to identify sulfur acid compounds such as FeSO4, FeS, FeS2.

I chose SrCO3 and CaCO3 to make this acidic atmosphere to the neutral condition.

I understand the chemical reaction between sulfuric acid and Sulfur dioxide ion with SrCO3 or CaCO3.

But most of the iron-sulfur compound is FeSO4.

FeSO4 can react with SrCO3 or CaCO3 to produce SrSO4 or CaSO4(which is a stable compound) and FeCO3.

Thank you.

Clostridium acetobutylicum is a solventogenic bacteria, still can it use C1 compounds like CO and CO2 as substrates for fermentation process.

Using a muffle furnace, I synthesised several ferrite materials with varying sintering temperatures. Cotton and wood are used inside a muffle furnace, but they are not burnt since the muffle furnace is kept at a higher temperature. why?

Anyone who can share the standards or guidelines required for wood/biomas to produce charcoal. E.g. Moisture content values, fixed carbon, volatile mater, ash of the wood.

Thanks

Dear Wetland scientists,

We are currently carrying out a synthesis about every “rapid” tool which can be used to provide information about conditions of soil saturation in wetlands at one point or over a short period of time.

We have already listed : alpha dipyridyl, orthophénantrolyne, FIRIS and MIRIS tubes and films, iron stick, wood stick, lead rich PVC tube, TDR and FDR, well, piezometers, maximum-minimum recorder, water-stained leaves, soil redox potential measurements. Note that we are also documenting tool pros and cons.

Please, do you know other interesting tools that we may add to this synthesis?

Yours sincerely.

Dear All

Modulus of rupture (MOR) and modulus of elasticity (MOE) are two parameters in heat-treated woods. In the following paper, the Authors used time, temperature, and relative humidity or wood species parameters for determining the MOR and MOE by Artificial Neural Networks (ANNs).

Are there mathematical equations and formulas for determining MOR and MOE with time, temperature, and relative humidity in standard codes and other papers?

Best regards

Most of conservationist advocates total ban on any human interference in natural forests including silvicultural management practices.will by doing so in terms of carbon cycle weheter old  tree stands as well as dead trees is increasing carbon storage or decreasing  by decomposition. That unused wood if utilised properly for lock carbon in natural furniture or structure will be more useful than laying in the forests. Is there any study which can suggest in decomposition of wood how much and carbon di oxide liberated or added to soil to increase soil carbon along with net gain of carbon after decmposition of wood. 

How can the mechanical properties of wood be improved? Are nanoparticles possible to improve this, and how can they be added?

Good morning.I am a graduate student in the College of Forestry, Guangxi University.I have read the article《Brittleheart as a critical feature for visual strength grading of tropical hardwood: Approach of detection》.I don’t quite understand some parts of this article. May I discuss it with you?

(1)When we characterize visible CF’s，how do we know if the CF’s are caused by brittleheart(compression failures) or Wood splitting or wind.Because I have cut some wood(very distinct,with fibre separation) to characterize CF’s,but I can’t find fibre bucking in microscope（image0012).

(2) I cut it perpendicular to the surface of the CF'S to get the longitudinal tangential section(Figure DSC08441). Is this cutting method correct?

I'm looking forward for your reply!

Hello!

I have an upcoming research on binderless wood particleboard that uses hydrogen peroxide and ferrous sulfate to "get the lignin out of the wood cells" by oxidation. However from my literature searches, it seemed that there is no exactly defined concentration for H2O2, and that other fellow researchers only describe the amount of mass they use (for example, 5% of the dry particle weight). What exactly is the concentration that we need for the lignin oxidation? My target time is 15 minutes of oxidation in 29 C and 65% RH. If i may cite the research, this was the reference for the method:

Suhasman, S., Hadi, Y.S., Massijaya, M.Y. & Santoso, A. (2012). Binderless Particleboard Resistance to Termite Attack. Forest Products Journal, 62(5), 412-415.

Thank you, and i will very much appreciate the answer.

Greetings,

I've been searching for days in databases to find the correlation between porosity in materials (for built environments like porcelain, ceramics, wood, etc.) and biofilm formation (index of bioburden). The findings will help me then understand the correlation between porous/non-porous materials and their cleanability properties.

Thanks

It has been reported that chemicals used for finishing hardwood furniture and hardwood flooring may potentially cause health effects since they can cause cancer. The California Proposition 65 law outlines potential health risk of such items which are listed as cancer causing. In spite of such regulation, people have been using hardwood for years. Where is the fine line between use and not to use? Does it bother you to use hardwood for residential and commercial purposes? Is there any such regulation (e.g., Prop 65) elsewhere?

Dear colleagues

I am looking work that describes the characteristics of exhaust emissions from combustion process of wood and straw (comparison)?
