Please confirm male or female , age , continence. retrograde urethrography identifying duplication or possible ureterocele or diverticulum. Also exact opening of the UO's with any anomalous renal presentation. This is a complex case but needs more information for cohesive analysis.

There are no giant long-necked sea turtles, In addition, if it lived in fresh water it would not be a sea turtle. The long-necked turtles all live in tropical or subtropical climates. This is just a silly question.

Thank you for the reply Yetoka Abraham Swu !

Most of the time we will only have engineering curve. I think the main problem here is the true stress-strain data after necking.

1. Start in the Ansys Workbench by selecting the Simulation tab and then click the "Materials" icon.

2. Select "Edit Material" from the drop down menu. A window will appear with several tabs. Make sure the "General" tab is selected.

3. Enter a name for your material, select the "User Defined" option under Material Model, and select "Nonlinear" in the Nonlinear Model drop-down menu.

4. Use the "Add Data" button to select your experimental data. Make sure to select the appropriate units for your data.

5. In the Data Settings tab, select the appropriate model type (i.e., Stress-Strain, Creep-Stress-Strain, etc.) and interpolation.

6. Select the appropriate units for your data and enter the Number of Data Points and Maximum Time for your data series.

7. Click the Apply and OK buttons to complete the material model definition.

Vipulbhai VIRABHAI Solanki Thank you for your time and comments sir, but this is not the type of course I was looking sir, as I want a certified course which teaches chemo and radiation oncology whose entry requirement is a MDS oral medicine and radiology from India, for me to practise as a clinician back here in India sir.

Use two-parameter family in this case as: 2rx(1-1.5x), replace 1.5 by another parameter. You can do iterations like this:

I hope that it will help.

Thanks everyone for the great insights

You cannot expect the whole slide to be absolutely perfect. I suggest using the current protocol as any deviations may deliver worse outcome. You never know beforehand. Be aware: when you try a new protocol you are not necessarily improve the staining. However, you may need to be careful when placing tissue into an embedding frame/cassette before submerging the block into paraffin. careful, accurate placing of the tissue will deliver a better sample for future cuttings. people are using few tricks to ensure the perfect location of the tissue in the block, please read this protocol here Tissue Processing Overview: Steps & Techniques for Histopathology (leicabiosystems.com): Steps & Techniques for Histopathology (leicabiosystems.com)

Laxman Subedi Thank you. Sorry for late reply

A loupe with at least 3 to 3.5x magnification should suffice.

You're welcome :)

Hello. Although there are no official guidelines for treatment I recommend that you have a look over "Deep Neck Space Infections Empiric Therapy" in 2020 on Medscape.

To safely and effectively use these reagents, glassware should be oven or flame dried, then the air displaced with a dry, inert gas (often nitrogen or argon). This creates an "inert atmosphere" inside an apparatus, one that will not react with the reagents.

Uwe Yacine Schwarze Thank you for the suggestion

Thank you for looking into this point, Dr. Singh!

But what about exploring the role of central venous excess pressures in archetypal multiple sclerosis with its vein-centered brain lesions?

It was great to learn what you think RE the link

https://medium.com/@franzschelling/what-deals-the-brain-such-blows-synchronous-at-least-double-hits-in-an-exemplary-case-of-292877844500 ... or also what's added below.

Mostly they are suffering from Neck injuries i think...

In any way you will be able to use a fiberoptic laryngoscope and ready for alternative intubation such as emergency tracheastomy.

I feel it difficult to answer this thread. I don't think that strain hardening exponent affects the necking position of the sheet during the forming process. The thinning of the sheet takes place at the weakest point.

Please go through the following RG links.

I agree with Paresh Chandra Ghosh

Hi mn ma

I think you would most probably need to input some material damage mechanism, i.e. ductile damage. The simulation looked fairly accurate in general. The deviation towards the end, highlighted by the difference in neck radius, most probably is some damage or void nucleating within the real material, but not within the model.

Have a look at https://books.google.com.au/books?id=bCcxDwAAQBAJ&pg=SA4-PA7&lpg=SA4-PA7&dq=remnant+volcanic+neck+detection&source=bl&ots=7mC_XZCQL_&sig=ACfU3U08L2ZGwG-zcUT1IQMEaZVa8YEMRw&hl=en&sa=X&ved=2ahUKEwj8nejmhKPoAhXKzzgGHUqlBQQQ6AEwDHoECAgQAQ#v=onepage&q=remnant%20volcanic%20neck%20detection&f=false

Dear Luqing Cui,

To the best of my knowledge, in the fatigue fracture surface, the area corresponding to the initiation region, propagation region and final fracture is dependent on various parameters such as the toughness of materials, fracture toughness, loading mode, max to min stress ratio, applied stress to yield stress ratio, temperature and so on. At first glance, in my opinion, the shown overview fractograph of the fracture surface is not representing the occurrence of necking. As you know, at the low-cycle fatigue regime, the crack initiation stage takes the small number of cycle of whole fatigue life and occurs at the smaller number of cycle in respect to propagation stage. In this case, it is obvious that area of the crack propagation region is considerably larger than crack initiation region. Also, the final fracture region has a smaller area than the crack initiation. This observation demonstrates the acceptable fatigue performance and the serviceability of the alloy in the mentioned conditions. In other words, the material has displayed a good fracture toughness during the fatigue straining. Also, in the case studies, the ratio of the initiation area to final fracture area is considered as an important parameter to evaluate the fatigue performance.

In summary, at the low-cycle fatigue regime, the area of fatigue crack propagation region must larger than fatigue crack initiation region. This strict viewpoint would not be exist for comparison of the area of initiation and final fracture region in the fracture surface.

I hope I have helped.

Regards

Hi Hamid Reza Attar ,

according to the change of the behaviour at strain=1 this is purely mathematical since the exponent is n<1 (it's like the behaviour of square root). I believe that you care about cases with strain values much lower than 1. So, an increase in strain hardening exponent n results in less material necking since it represents a more "elastic" material behaviour. Check the following:

https://en.wikipedia.org/wiki/Strain_hardening_exponent

Occasionally, it is a single vein rather than a venous plexus.The venous plexus of hypoglossal canal also known as plexus venosus canalis nervi hypoglossi, circellus venosus hypoglossi and rete canalis hypoglossi is a small venous plexus around the hypoglossal nerve that connects with the occipital sinus, the inferior petrosal sinus and the internal jugular vein.

The cervical epidural veins are connected superiorly to the suboccipital plexus and to the anterior condyloid vein, which is in continuity with the inferior petrosal sinus. Laterally, the cervical epidural veins are connected to the vertebral plexus that surrounds the vertebral artery in the transverse foramen

Dear Dmitry, yes, I used NaCl flushing of the arteries before fixation,

Thank you all for your help. I found what I needed in the appendix of the following article:

Funk, F., & Todorov, A. (2013). Criminal stereotypes in the courtroom: Facial tattoos affect guilt and punishment differently. Psychology, Public Policy, and Law, 19(4), 466-478. doi:10.1037/a0034736

A linear behavior in the hardening model just after the maximum engineering stress is a simplification of the real behavior of the material, but it gives you a simple model with one variable: the slope of this linear hardening Ep. You can modify this variable until obtain the most reliable result with the experimental tensile stress-strain curve.

If you use an exponential stress-strain curve instead of bilinear, it is not a bad option. You do not know the real behavior of the material after the necking. You are doing approximations, so both of them could be good enough. You have to define the parameters of your exponential model until reach the most accurate result with the experimental tensile test.

Had a similar case few years ago, the decision was to observe the patient. You could always discuss it with the colleagues at your hospital's Tumour Board meeting.

Hi Meysam Khodaei

Thank you very much for the reply! I will contact you if there's any further question.

The barriers on the way of nutrient recovery can be summarized as: 1)Technological, 2) Economic, 3)Political, 4) Social and 5)Legal. According to my understanding the main barrier is low phosphorus price in the market. However, I assume that you are interested in technical aspects of this process:

1) The enhanced biological phosphorus removal is the most relevant technique for P-recovery in full-scale. However, the EBPR may not perform well under different operational conditions.

2) The low overall efficiency of P-recovery is a challenge since we loose a significant part of Total-P in the sludge.

3) The recovered product is mainly considered as potential fertilizer. However by current technologies the quality is not good enough even as fertilizer.

In brief, we just started to understand the importance of circular economy and resource recovery. I believe that during time we can overcome majority of these barriers.

Hi Volkan Ili,

I am afraid that the answer to your first question is yes, the linear perturbation is purely static, so any dynamics/temporal effects are lost, you will see only the linear stiffness effects = the tangent modulus.

On the subject of comparing bifurcation and perturbation, I can't really suggest studies I'm afraid, and I'm not that familiar with your field to give you good advice without reading up on it. But I wish you good luck with your work!

Dear N. Belloumi

Thank you for your concern. Yes, that's the question!

if your data are interval or ratio and the groups are independent, you can use t test for independent samples, given that data are normally distributed and there is randomization for tbe assignment for both groups. If the data are ordinal and the grojps are independent, you can use Mann Whitney U test.

The point is : do you just want to make curve fitting or do you want to really understand the material's behavior?

In the later case a unique charge curve isn't enough.

So if you only have the tensile curve, whatever fits the charge curve can be considered as good but may have no physical meaning.

Yes, is available.....

I suggest, you observe and calculate species abundance for ith species from your data set separately. Shannon and Simpson indices represent the diversity of a community as whole.

hello Dibakar

Second link is not working.

Dear Yeasir Arafat, my suggestion is:

Step 1: let Material 1 E=10 GPa, and check the results of the solution

Step 2: if step 1 is OK, start to decrease Material 1 E gradually and each time check the results.

I think you will discover the problem.

Best wishes...

My grade corresponds to make a dynamic modeling movement flexo neck extension, by analogy with a pair perform rolling,. I have little information about it, for example I have a picture that explains what I want to do my job.

I need to make a quasi-static analysis, simulated numerically in Matlab

It is not clear to me if  you have a ice bath around your reactor, but I presume that cold finger was placed to fast removal of heat, that means you probably have an important exothermy in your reaction and it has to be conducted at low temperature.

Very good points. This is the way to avoid the upper cross syndrome.

Thanks Prof. Badr.

Dear Anbreena,

I know a researcher who has done studies in CANS. Her name is B. Huisstede.

hopefully benign- we would proceed to US guided core biopsy -

breast/lymphoma markers etc

Any survey, including the BORG scale, will be pretty vague and vary a lot between individuals. Monitoring the MEDIAN FREQUENCY of an EMG signal would be more sensitive to a change in fatigue status.

the neck appears numerically when the slope of the behavior law is lower of the stress value. With explicit code the wave propagation will help by localising the neck area by creating the instability, for implicit code the localization comes from other instabilities mesh, accuracy, type of elements ...

Hello. I extract RNA from different tissue types and it is best to add trizol sample and homogenize with Ultraturrax. If you extract the RNA with Kits'll lose lots of it.

For storage, if you´re only going to extract RNA, it is best to add trizol and freeze at -80.
