Question

In order to play music on a piano, you have to press keys. Other affordances such as "jingle playability" exist and necessitate the same affordance.
"Moving a finger" is required to press keys, but if you can't move your fingers, you can't press a key, and you can't play music. This propagation doesn't work the other way around - not having the affordance to play music doesn't limit one's ability to move their fingers.
Relatedly, in McGrenere and Ho's paper, they suggest that there are affordances that only open up after others are taken, or at a specific time, referring to these as "sequential". An example they gave is a UI dropdown menu, which I feel is a poor descriptor considering it's one action that affords multiple others. Using "subsequential" to describe clicking on any item in a menu popup, for example, becomes confusing as all of them have "clickable" as a nested affordance, and all of them are next in the sequence.
I would suggest that these be combined; you could describe "pressing keys" as nested within the range of affordances allowed by "moving your fingers" in that situation, just as you could describe "selecting an option from a list" as nested within "clicking the dropdown button".
But maybe I'm missing something - could someone explain the thought process behind this? Here is the paper I'm referencing:
Relevant answer
Answer
Piano music playability cannot be referred to only "pressing keys". This is much more complex process serving by haptic perception, mental haptic imagination and audio perception. The kinesthetic component at that is the most important thing that translates/integrates multimodal information into to the (mental) space of the piece of music.

Science approximately derives from philosophy thus, at some point, software is at least subconsciously based on a particular epistemology more than other epistemological schools. How can we base software on critical rationalism?
Relevant answer
Answer
Software based on critical rationalist epistemology can focus on promoting falsifiability and rigorous testing of hypotheses. It should support iterative refinement, facilitate critical feedback, and ensure transparency in how data and conclusions are derived.

Hi all,
I'm looking for any studies that have used or using Design Thinking, in or across longterm projects in organisations. Studies that have implemented DT or measured its impact over a period of years would be preferable
Please let me know
Many thanks in advance

Relevant answer
Answer
P.J. White P.J, We consulted implementing design thinking for small and moderately large companies. In my experience it’s potential falls flat because its hard to describe what we want, imagine, and/or give one anther our “sensibilities” and “instincts”. Plus, in 20 years communicating behind digital tools has blunted that ability.
An unmentioned complaint, there’s a lack of joy, spirit and soul in the initial concepts, work and finished product. But because we’ve gotten better at reducing costs management remains in favor of design thinking.
Depending on your background in the arts and science or business and finance (typically) there’s a wide chasm of what design thinking means. The thought process and language in different fields plus the sense of what each field considers insightful and well thought out is different. That’s been known for a long time as are established work arounds. But today the speed of new (good or bad) ideas increases this kind of misunderstanding.
The prospect of becoming creative and discovering insights that lead to new ideas is very exciting. Introducing the concept via IDEO, Apple, Braun, the better fashion, graphic and architecture companies adds a passion and desire to be part of design thinking and creative work.
However, in my opinion, none of it matters. The people who can work and make things this way have qualities of wonder, play and knowing how to learn. Anyone used to experimenting, failing and having a sense of what to try next, who hasn’t forgotten how to play, and especially uses all their physical, emotional and intellectual senses tend to “get” design thinking. The best thing I know is to moderate a variety people of all ages cultures, genders working together and then get out of the way.
Yes, that’s what design thinking hopes to achieve. It doesn’t. Too often, like most modern teaching, it's told in only one of our senses, "verbally". As if we all think and imagine the same way. Like most teaching, that assumes the same thing it misses the nature of how we experience people and the world around ourselves.

"Online Education is going to be a new normal."
As the world is moving (or forced to move) towards the online mode of education what and how the field of Design and Architecture Education is going to reconfigure itself? In a skill, mentor, material/physical resource based discourse, the challenge is to find a meaningful, competitive and progressive alternative to the established paradigms. Or do you think the old paradigms (like Bauhaus or Ulm) are obsolete in the current state of affairs.
Relevant answer
Answer
The mode of designing education can be different, and evaluating good or bad may require analysis based on specific contexts. The online teaching mode can serve as a supplement to the offline mode, but it is probably impossible to replace it because the advantages and experiences of online and offline are different.

Question

I need to anneal mm-scale samples made on Si substrates up to 600°C.
To temporarily mount them, I've seen things like high temperature epoxies, tapes, and pastes as well as mechanical mounting methods. An adhesive would need to be thermally conductive, able to withstand temperatures up to 600°C, non-magnetic, and easily removed from the sample without residue or damage. A mechanical method may be the easiest (slots, clips, screwing down gently under a washer, etc.).
To heat them, I'm looking into different heaters and designs. One possibility is a cartridge heater that I can insert into a piece of metal (like Cu) that can have samples mounted on top (either with adhesive, sitting in a slot, or something else. I've also seen flat heaters: maybe the samples could sit on one of these directly and somehow be mounted.
I'm not sure how to best do this. Any tips or information about how you mount or heat your samples are very appreciated!

To my knowledge, water glass, because it is an aqueous solution, should not etch, corrode, or react with silicon. Sodium silicate dissolved in water is a fairly benign solution. As far as removing dried sodium silicate, if you are willing to wait, hot water and a dunk in an ultrasonic bath should work.
I mean compare water glass with epoxy. Even aerospace types of epoxy, to my knowledge, cannot take 600°C, see the following URL: https://www.hisco.com/henkel-aerospace-adhesives?utm_term=aerospace%20adhesives&utm_campaign=Lead+Gen+%7C+Henkel+%7C+PP&utm_source=adwords&utm_medium=ppc&hsa_acc=8827094775&hsa_cam=19310059336&hsa_grp=143200195623&hsa_ad=642010110713&hsa_src=g&hsa_tgt=aud-936910285664:kwd-337348563058&hsa_kw=aerospace%20adhesives&hsa_mt=p&hsa_net=adwords&hsa_ver=3&gad_source=1&gclid=EAIaIQobChMI9_zqh9HIggMVj0hHAR3TpQusEAAYAyAAEgJyFPD_BwE And even if they could take 600°C, how would you remove them? I once had to reverse engineer a circuit board potted (encapsulated) in epoxy. I had to soak it in lacquer thinner for several days to soften the epoxy, and then use dental picks to scrape away the softened epoxy residue.
As far as using nickel, you don't need a solid block of nickel, you could simply electroplate the nickel onto a machined copper block. You coud also used chromium, platinum, palladium, or iridium. Commercial electroplaters can provide the electroplating service to you, but don't forget to tell them that the plated object will be subjected to 600°C. They might know some organic brighteners, they can add to the electrolytic bath, to reduce the grain size of the electroplated layer.
Good luck.

I'm writing my dissertation on the visual aspeacts of the 80s Memphis Design Movement and I'd love to know any information anyopne has or any opinions on said movement from those who lived thought it.
Relevant answer
Answer
Ash Frank Ash, sorry this is so late. ---First a link to a 2021 New York Times article; “How the Memphis Design Movement Made a Comeback”
Please excuse the long link. Its on way I know to share it to other countries. (let me know if it fails)
Memphis design first arrived in the US when our interiors and furnishings where modern and clean. Due in no small part to the design ideas and work of Frank Lloyd Wright, Marcel Breuer and the the father and son Saarinens, Knoll, Ray and Charles Eames, and both Albers.
Memphis Design arrived in US at a time when most of the homes and offices that cared about design were composed with neutral colors. Color was an accent not a theme. From the upheaval of ideas about art, music and design in the late 1960's it took 30 years before we saw it incorporated into daily life. - To put this in perspective, we didn't paint our walls with color until the 1990's. Before then it was tinted neutrals.
To me personally, at the time, Memphis Design didn’t work in the US. And the revival came off as an awkward idea. Awkward as in it it was an interesting diversion but felt more out of place in our culture now than the first time around.
Between late 60's and mid 90's US design was being upended by ideas coming from the California artists and designers (southwest coast of US). Plus coming influences of music and new ideas in graphic design. Our sense of art and design had been more insular. But fashion design introduced us to other design from around the globe.
In the US we have 3 traditional centers of furniture design; one each for east central and west parts of US. Memphis Design was exhibited but didn't find commercial and corporate buyers. It was the exhibit everyone came to see but few "bought-into" the look.
Instead the US responded to new visual ideas in graphic and fashion design. Along with music that was how the majority of US people broadened our ideas of other forms of design.
I was in Philadelphia, Pennsylvania (near New York city) and watched our architecture shift from modern to the post-modern building style & embellishments of Robert Venturi and his wife Denise Scott Brown.
When Memphis Design arrived I saw in our art magazines and first thought it was “Memphis” as in from Memphis, Tennessee. It reminded me of the free-forms of graffiti and west coast “surf” style.
In general, we loved seeing and talking about it; but liked it better if it belonged to someone else. My opinion; we liked it as an addition but not an everyday items. Like an “accent" piece.
It was reviewed and shown in many US magazines and design showrooms but overshadowed by way too many competing ideas. -- However, to me, it didn’t fit with US design. Even the recent revival didn’t seem to work. Its hard to explain. To me it made perfect sense in Italian and Greek culture. Possibly Central and South America. Less in Asian and North America.
I'd sum it up saying Memphis Design is intriguing. And did well explaining itself. But missed being something that engaged us beyond the initial intrigue. Personally, I didn't like it. And liked it less the 2nd time.

If you look at a typical Ashby diagram, you will notice that the fracture toughness based on K-factor is superimposed on all material classes.
Is this an ingenious solution or is it too simple?
Relevant answer
Answer
The inclusion of fracture toughness based on the K-factor on an Ashby diagram can be considered an ingenious solution. The K-factor is a measure of the stress intensity factor at the tip of a crack and is a critical parameter in determining the fracture toughness of materials. By including this parameter on the Ashby diagram, it allows for a quick and easy comparison of the fracture toughness of different materials, regardless of their class or composition.
However, it should be noted that the K-factor only provides one aspect of the material's fracture behavior and other parameters such as crack growth resistance and microstructure should also be considered when selecting a material for a specific application. Additionally, the values on an Ashby diagram are typically plotted for a specific set of testing conditions and may not accurately represent the fracture toughness under different conditions. Therefore, while the inclusion of K-factor on an Ashby diagram is a useful tool, it should not be the only parameter considered when selecting a material for a specific application.

Is there a data sheet somewhere listing building requirements for staircases across various European countries?
I am based in the Netherlands, and trying to design a staircase.
The 'bouwbesluit' (building regultaions) of the Netherlands is very different from its neighbouring countries of Germany and Belgium.
The building regulations cover things such as minimum width of staircase, maximum angle, maximum height of one step, and minumum horizontal distance of one step, etc.
I am curious how I can design a staircase that would be practical to build in multiple different countries.
Is there any collected data on this that includes multiple countries?
I would be very interested if other people have encountered a similar problem?
Relevant answer
Answer
Dear Dr.,Julius Riese,
Stair Building Guidelines
The UK Building Regulations on staircases are often the first source. Consult when building a new staircase because they are widely recognized throughout Europe as well as in many countries in Africa and the Middle East. When precise specifications are required, we collaborate with clients and building officials to create a stairway that is tailored to meet their needs.
Please refer to the links below; you can get the correct building codes for stairs for numerous nations.
  • Minimum tread going: 9 inches (229 mm) excluding the nosing
  • Staircase steepness is 2R+G = 24.6 inches (625 mm). A value for the rise-to-going ratio of 17/29 ˜ 0.59 is considered optimal, this corresponds to a pitch angle of about 30°.
  • Variance on riser height and tread depth between steps on the same flight should be very low.
  • Maximum nosing 1.25 inches (32 mm)
  • Height of the handrail. This is normally between 34 and 38 inches (864 and 965 mm), measured to the nose of the tread. The minimum height of the handrail for landing balustrades may differ and is typically 36 inches (914 mm).
  • Maximum space between the balusters of the railing. This is typically 4 inches (102 mm).
  • Headroom: At least 83 inches (211 cm), alterations may apply.

As it is evident, due to climate change and global warming, as well as energy shortage, there is a crucial need for energy consumption reduction and carbon contamination reduction in households as a major part of these events. One of the novel solutions for managing these problems is digital twins for better management in the construction and also maintenance processes of homes. I want to know:
Firstly, how much could this method be effective in this situation?
Secondly, what are the mechanisms and methods for this system?
Best regards,
Hossein Pouresmaeil.
Relevant answer
Answer
Digital twins could be highly effective in the context of carbon neutrality and energy consumption reduction in the home sector. By leveraging the power of data, digital twins can provide an accurate picture of energy consumption and allow homeowners to take proactive steps to reduce their energy consumption and emissions. For example, digital twins can create detailed energy models of individual homes, track energy usage in real-time, and provide insights into how different energy-saving measures can impact energy consumption and emissions. Additionally, digital twins can also help homeowners optimize their energy usage by providing personalized recommendations and alerts. Ultimately, digital twins can be used to empower homeowners to make better decisions about their energy consumption and reduce their carbon footprint.

What are the differences between shop drawings and builder works drawings, and what are the differences between them?
As their name clearly states; shop drawings are drawings produced by the shop; ie. as an example when a client buys an equipment for installation the shop produces drawings; called shop drawings; for the subcontractor to implement.
Builder works drawings; as their name implements also; are drawings produced by the builder or subcontractor who is responsible for executing works. Builders use builder work drawings on site.
The shop drawings; produced and used by the by contractor engineers based on design drawings; details are based on standard specifications and tender requirements. On the other hand builder works drawings are produced by the subcontractor based on shop drawings, and used by his engineers and builders, builder works drawings are based on the details of equipment the subcontractor is planning to install; and must with shop drawings details.
The consultant compares shop drawings with approved design drawings, and work on site with shop drawings for final approval.

Answer
A builder work drawings will provide in detail the component representation and client communication of what the engineer designed. Contrarily, shop drawings is for fabricators and technician use only and it is basically for determining how components will be produced and placed during the construction process.

Answer
In the US, over and over we witness the needs of people with low incomes, diverse cultural ideas and the wrong color skin routinely deprived of basic human services and educational opportunities. I’d like to suggest that design as a way of thinking (vs making objects) can be part of changing this. But we’ve studied this, created awareness and used grants to fund small endeavors to bring change.
More often we fail. We fail because our ideas have little to do with things people want and their values.

Does anyone have experience in designing multi-story wastewater treatment plants?
In fact, I want to reduce wastewater treatment footprint because we have a problem in terms of land.
Relevant answer
Answer
I could tell you many "stories" about wastewater treatment plants (WWTP's) but I guess that mean "storey" (multi-level). As a matter a fact we designed one about 30 years ago in South-Korea where the footprint was so small that we installed a 3-level/storey WWTP including a stack of 2 final clarifiers (one on top of the other). Many more levels could be added as needed. This is a matter of proper hydraulic design (gravity flow and pumped flow) combined with efficient construction design (civil & structural works).

Through multiple empirical studies, I have collected user needs for an ICT intervention. During this study, I intend to design a prototype and then evaluate the prototype to check whether user needs are captured in the proposed design.
What is the most suitable approach? Quantitative, Qualitative or mixed?
Are we evaluating the features of the prototype or evaluate the user requirements?

Hello Manoja Weerasekara , even though think-aloud protocol is considered by some authors as a widely used method for usability testing of software, interfaces, websites, and (instructional) documents. It is possible to perceive the satisfaction of users by his/her expression, frustrations, frictions and comments. An interview or Likert scale could be added after the Think-aloud procedure, focused on user's satisfaction with the experience.
The basic principle of this method (Think-aloud protocol) is that potential users are asked to complete a set of tasks with the artefact tested, and to constantly verbalize their thoughts while working on the tasks.
From all possibilities of prototype testing, the Think-aloud Protocol is the most
suitable choice to help observe usability and interaction problems from users’ point of view. According to Villanueva [4], the technique consists of a researcher observing 1–4 users doing specific tasks within a controlled environment. The user’s actions and thoughts are to be described verbally aloud by him/herself on real time. The researcher records the user actions by written notifications, video or voice recorder.
The participants are to perform a simulation of tasks using the prototype. The Think-aloud Protocol has to be executed individually and the steps of the task to be closely observed with participants verbalizing actions, thoughts and confusion: do users understand what is the app? Do users cognitively understand icons and actions to take? What is the visual perception of users regarding colors, types, size, icons and visual impact? Is the process an easy and smooth experience? How do users explore the options?
Nevertheless, I've been feeling that for remote research, cooperative evaluation can be more useful e easier to execute.

Question

In my current project, I want to answer if various cognition items (ratio, 30+ of them, may get reduced based on a separate factor analysis) predict moral outrage - in other words, do increases in item 1 (then item 2, item 3, etc) predict increases in outrage in a significant way. Normally, this would be a simple regression. But then I complicated my design, and I'm having a hard time wrapping my head around my potential analyses and whether it will actually answer my stated question, or if I'm over-thinking things.
Currently, I'm considering a set-up where participants will see a random selection of 3 vignettes (out of 5 options) and answer the cognition items and moral outrage about each. This complicates matters because 1) there is now a repeated measure component that may (or may not?) need to be accounted for and 2)I'm not sure how my analyses would work if the vignette selection is random (thus, all vignettes will show up the same number of times, but in different combinations to different people). I am anticipating that different vignettes will not be equal in their level of DV (which is on purpose - I want to see if these patterns are general, not just at very high or very low levels of outrage).
When originally designing this, I had wanted to average the 3 vignette scores together for each subject, treating them as single, averaged item values to use in a multiple regression. But I've been advised by a couple people that this isn't an option, because the variance between the vignettes needs to be accounted for (and the vignettes can't be shown to be equivalent, and thus can't be collapsed down in analysis).
One potential analysis to combat this is a nested, vignette-within-individual multilevel design, where I see if the pattern of cognition items to outrage is consistent between vignettes (level 1) and across subjects (level 2), to account for/examine any vignette-by-cognition/MO pattern interactions. And this makes sense, as MLMs can be used to compare patterns, rather than single scores.
But I can't wrap my head around what part of this set-up/the output I would look at to actually answer my question: generally, which, if any, of these cognition items predicts outrage (regardless of vignette, or across many scenarios)? And can this approach work when the vignettes combinations differ between subjects?
Or is this the incorrect analysis approach and another, simpler one would be more fitting? For example, is the averaging approach workable in another format? What if all vignettes were done by all subjects (more arduous on the subjects, but possible if the strength of the analysis/results would be compromised/overly-complicated)?
Confirmation that my current analysis approach will indeed work, help with what part of the output would answer my actual RQ, or suggestions for an alternative approach, would be appreciated.

Hi dear Santiago.
Real architecture is called architecture in which human thoughts and feelings are taken into account and this architecture creates a perfect fit that pays attention to structure and function at the same time. We know that our relationship with nature promotes health and well-being, and this relationship can also improve physical function. People who live in a building do not just need to work, play, eat or sleep. They want to be inspired and inspired by their surroundings, to feel comfortable and strong in it. They need a space that makes them more comfortable. The solution to architectural sustainability is to work in harmony with nature. That is, one must understand nature, explore it with sensitivity, and at the same time avoid damaging nature's systems. The architect-planner should pay attention to the concept of biophilia, which causes the continuity of performance and health and emotional states of residents and individuals and leads to positive reactions in the environment, and the general process in the architectural predominance to such things as:
1- Making natural and physical frameworks friendlier
2- Optimal organization of energy consumption
3- Ensuring the effective relationship between human progress and optimal management of natural resources in reducing the negative effects of climate change.

Answer
There are various types of pollution, so each one or combination may take a specific survey or inventory, and assessment. Some of the various types may include solid waste, sanitary waste (human, animals, pets, etc.), industrial wastes, air pollutants, water pollutants, soil pollutants, etc. Coming up with a working proposal would probably necessitate involvement of leaders, community, landowners, and others interested, such as industry, hospitality such as hotels, citizens, etc. Leaders might include political representatives, health, religious, agencies, police or enforcement, various technical pollution experts, etc. Funding to develop comprehensive plans, improvements and management as well as monitoring may be another important area to address. Plans or programs might be developed to help address specific types of pollution, or circumstances, and some of these might be voluntary citizen responsibilities, and some might be legalized or regulated, and funded by taxation, communities, industries, or government actions.

Relevant answer
Dear PJ White,
Participatory design (originally co-operative design, now often co-design) is an approach to design attempting to actively involve all stakeholders (e.g. employees, partners, customers, citizens, end users) in the design process to help ensure the result meets their needs and is usable.
Benefits of Participatory Design in Web Development
The most attractive benefit of the participatory design is bringing a fresh, unique set of eyes into the design process. Developers and engineers work daily to create web designs and interface models, but do not share the same perspectives of end-users
Co-design, design with users, not for them. Participatory design you design for users and get their input.
A human-centered, systems-minded, and strategy-aligned design approach for social sector leaders. ... Strategic planning is logical and ensures that an organization's activities actually lead to its intended outcome, rather than busy work. Human centered design is action-oriented, deeply human, and experimental
The design thinking process is broken up into five specific design thinking stages: empathy, definition, ideation, prototyping, and testing.

Does it has do to with the related enabling technologies?
Relevant answer
Answer
In my opinion, despite the fact that the history of drone development dates back to 1917, it was only at the beginning of the 21st century, i.e. one hundred years later, that the technology and applications of drones developed, which is related to the ongoing technological progress in various supporting technologies in the field of batteries that store electricity, plastics materials, ICT information technologies in remote control applications, etc. Besides, it is only in recent years that the development of drone applications has occurred. In 2020, the SARS-CoV-2 (Covid-19) coronavirus pandemic also caused an increase in the use of drones. Currently (December 2020), in the context of the pandemic, drones are used to transport medicines for sick people, drugs and food to places with poorly developed road communication, blood plasma of people who have recovered from Covid-19 disease, etc. In the future, drones will find many more applications as equipment for courier companies delivering different products to individuals. Moreover, conceptual technological solutions for the construction of flying cars, which are also drones, are currently being created. Transport flying machines are also built, which with their shape and avionics technology were created as a combination of the concept of a helicopter with a drone. This type of progress in the field of avionics would not be possible without, for example, constantly improved and more efficient batteries that store electricity, more and more perfect electric motors and devices that charge said batteries with electricity. Perhaps in the future, as part of the ongoing technological progress, the growing demand for electricity, the growing demand for drones and the growing importance of environmentally friendly energy sources, drones will be produced powered by photovoltaic panels, which will cover the drones.

Relevant answer
Answer
Let's see. Breaking this down into its separate components, start with the simplest.
The maximum delta lift distance, from max down to max lifted, is going to be 2L. At its lowest point, the distance from the floor to the vehicle would consist of only the height of the stand and that top block.
The maximum Fs, which would be the maximum tension experienced by the long screw which lifts and lowers the jack, would be F*sin(α). As the jack goes from full down to full up, that weight goes from being entirely held up by the screw (sin(90) = 1) to being entirely held up by those four L components (sin(0) = 0).
And as you might therefore conclude, at max lifted position, F1 = F2 = F3 = F4 = 0.5*F. That's because when fully lifted, the weight is held up equally by F1 and F3, on the left, and by F2 and F4, on the right, while at the same time, at that fully elevated position, the long screw holds up none of the weight.

Hi,
We conducted an experiment analyzed by multiple regression. We measured each participants' personality with HEXACO model and their accuracy in the task. Our predictors are the six dimensions of HEXACO and criterion variable was their accuracy.
So what is the design of this experiment? Is this a repeated measures design?
Relevant answer
Answer
You may analyze it as a repeated records model, in which each of the six dimensions are explanatory variables. Then, you need to model your residuals to accommodate the fact that the same participant was evaluated across all six dimensions. An equivalent model would be fitting the random effect of participant instead of modeling the residuals - they will result in the same model.
One question is: how does your response variable look like? Is it categorical, proportion, or continuous quantitative? This will impact the type of statistical method to be used. For example, if it is ordered categorical, you need to use an ordered multinomial (logistic, probit, etc) regression. If it is proportion, then you may use Poisson/Negative Binomial. If it is continuous quantitative, then a simple linear model would be enough.
Please let me know if this is what you were looking for. THanks, Nick

Suppose I have a 100 Farad, 2.7 V supercapacitor which has a dimension of length = 45 mm and Diameter = 22 mm. I want to understand-how these length and diameter values were fixed and if any design equation is guiding it?
Relevant answer
Answer
The capacity of a supercapacitor can be measured in (F / g) or (F / cm2) or (F / cm3)
The working voltage = 2.7, indicates the maximum voltage to which the SC can be charged.
Using the equation:
Cs = I. t / m (Vf-Vi)
Cs = I. t / A (Vf-Vi)
Cs = I t / V (Vf-Vi)
Where i = is the discharge current
Where Vf-Vi = is the work potential
Where m = is the mass of the active material
Where A = is your area
Where V = is the volume, this can be found with the data: 45 mm and diameter = 22 mm.

Background
We have an RNA-seq project on small intestine. The experimental design were like this: Four physiological states, each with three individuals (biological replicates), each individual with two samples (two parts of small intestine), thus 4 physiological states × three individuals × two parts. The reason we included two parts of same individual’s small intestines is that we want to take consideration of tissue heterogeneity, by pre-analysis of these replicates the difference between two parts is actually not significant.
Question
Here is my question, when I applied a generalized linear model for the differential expression analysis on samples from two physiological states (e.g. DESeq2), should I treat samples as independent one thus 6 vs 6, or merge two samples from same individuals thus 3 vs 3. For the later one, can I regard it as technical replicate and merge reads from the two part together, or merge counts calculated from the two parts (e.g. collapseReplicates function in DESeq2). Or, should I include "individuals" as a blocking factor in the differential expression analysis.
There is an intensive discussion about biological replicates and technical replicates, like these https://www.biostars.org/p/54380/
but I am still confused about my situation, should I treat the two tissue parts from same individuals as biological or technical replicates.
Two parts of small intestine from same individuals, It's technical or biological replicates?
Relevant answer
Answer
Thanks Pro. Pan
It is a ticklish question to distinguish between technical and biological replicate in our situation, thank you for your time and your answer. The work the question from have been peer-reviewed and published (see details below). I’d like to share our answers. Firstly, we tried to answer two question, one is whether the variation between the two replicate is from biological factors (e.g. sex, age, or tissue heterogeneity), or from technical factors (e.g. sequencing lanes, library generation). It is reasonable that the two parts of small intestine were not biological replicates, just as you said, two samples were from the same individual and they shared same genetic background, then the variation between the replicates were from sequencing or other technical factors. However, as our original intention is inducing the variation from tissue heterogeneity, although they come from close part of small intestine, it’s not precise to just regard them as technical replicates and merge them in downstream analysis. The other question we want to answer is, how to take consideration of tissue heterogeneity but also avoid pseudoreplication caused by the same origian of the replicates. In our work, we randomly assign the two samples from the same individual to “PartA” and “PartB” and incorporate the blocking design into differential expression tools with ~sampled part + physiological states. By fitting design model above, we can compare the four physiological states with adjustment of the baseline differences from tissue heterogeneity (see details in )

I am currently working on the design of a 1-shell, 4-tube pass heat exchanger with 200 copper tubes. The purpose of the problem is to determine the affects of fouling on heat exchange area. Unused engine oil flows through the shell side and cold water in the tube side. The internal diameter is 15mm with a wall thickness of 2mm. I want to know if wall thickness and conductivity should be ignored in the calculation of the heat exchange area. I've tried out the calculation both ways, by first assuming that these factors are ignored and then by taking them into consideration and I noticed a significant difference between the two cases hence I am unable to decipher if it is wise to ignore the wall thickness and conductivity. I am aware that in most cases, with thin walled tubes, wall thickness and conductivity is ignored. Is it advisable to follow that approach of most cases?
