Hi Sina,

I would guess that the set name should not contain a slash.

El Hassan,

agree somewhat; but I also think that problematic to addictive drug users can stop if they really want to, because they do not have a disease, rather, are engaging in extreme behaviour for antecedent reasons---the 'demons' that they need to address towards stopping.

Modern approaches to sustainable management of urban greenery focus on integrating green infrastructure, such as parks, green roofs, and biodiversity conservation, to enhance ecological balance. Community involvement in urban agriculture and green projects fosters local ownership and responsibility. Innovative governance models facilitate collaboration among stakeholders, while long-term management strategies ensure the ongoing benefits of green spaces. Together, these elements contribute to healthier, more resilient urban environments.

All the theories you referred to can be used

Regarding the statement of the problem, you can combine two issues

1. the substance of the phenomenon i.e. what makes the phenomenon a problem? What is it about level of recreation program of detainees in jail that must be studied? How risky is it if this phenomenon is not researched into?

2. The gaps in literature that your study intends to fill

A combination of these two will give you a good statement of the problem

also be very careful cameras close to trails with high human traffic have a tendency to "disappear". We were looking at some animal presence/movement in an urban park associated with high human use and most of the cameras were stolen, locks cut and left etc. try to find someway to protect them - also this course is really good to take https://www.scr-cameratrap.com/

To resolve this error, you can follow these steps:

By ensuring that the keyword cards for step-dependent input appear after the first *step card, you should be able to resolve this error and run your Abaqus simulation successfully.

Release of much radiant energy in small space may be able to boost a 3D universe to a 12D universe. Time starts passing.

I think this kind of graph could be recreated using Python with the seaborn or matplotlib library.

Dear researcher,

I do like to assist you. Is it possible to change from athletes to players. The process is right but when you did not get enough respondents, what to do?

In research it solve by two ways ( in my knowledge);

1. Small sample size: 25 number of respondents (you can read detailed).

2. Go for broader platform. The shift of athletes to players is the broader platform.

Lastly, knock institutions of players (athletes), approach them via email and ask for assistance.

Wish you accomplished soon.

You use a combination of methods. You first use DNA extraction on your donor organism to obtain the DNA. You then use PCR to isolate the pieces of DNA of interest. This is then ligated into a vector (usually bacterial or yeast plasmids) and cloned for further manipulation such as mutagenesis and assembly into larger constructs. The final construct is then transfected into your recipient organism where it can be integrated into the genome by homologous recombination or transposons. One detail to be aware of is promoters tend not to express with the same strength or tissue specificity in other organisms and differences in tRNA amounts can affect the optimal codon usage resulting in differences in quantities of protein translated.

Adults seem to prefer clean and secure environment. Places where there's less noise and congestion. I think older people turn to prefer natural environment and to get closer to nature. Younger people seem to prefer sporting facilities and playing fields. They use these spaces mostly for playing and for training/ exercising.

It looks like you have PEC boundary conditions at the top and bottom of the picture. That would turn the right hand side of the picture into a wide waveguide with a mixture of modes in it, which is what it looks like. You should have open or infinite or absorbing boundaries top and bottom, like it seems you have on the right hand side.

Anders Børsting For sure, you can!

Hi Alexey Kuzin

Thanks for the answer. My results are based are based on the none hole case. Yes, I get warnings.

This question is very interesting. I agree with Julius that there is no fundamental difference in how recreationists perceive the field viewscape across activities, with the premise that those recreationists are skillful enough to travel across this section safely. In other words, skill and experience levels might determine their views and ability to focus.

I do think that social experiences might influence those recreationists' views. A hiker might feel uneasy on that section when seeing a mountainbiker riding toward her/him at a high speed. On the other hand, when seeing peers or other parties cruise that challenging section might increase one's confidence and thus change her/his view. My two cents.

Thanks for sending this interesting question!

Very interesting under the topic of CFD - Ansys - https://www.ansys.com/en-in/applications/cardiovascular

As part of forest management, including the so-called In forest management, the principles of sustainable development should also be applied, which consist in increasing the scale of taking into account the issue of biodiversity of natural forest ecosystems referring to natural forests instead of forest monocultures, which were previously created as part of productive forest management. In the situation of forest management in accordance with the principles of sustainable forest management based on the concept of a biodiverse forest ecosystem, the risk of pest infestation and diseases of many trees caused by microorganisms (viruses, bacteria, fungi) is much lower compared to monocultures of the stand. Therefore, the use of chemical tree protection products is also smaller, which translates into a lower level of environmental pollution.

Thanks for the papers, Dr. Nanco Dolman. It is interesting that the word "blue" has been added with the term green infrastructure. Many cities in the US are promoting green infrastructure for various reasons. In some places, GI method has been used for flood control and in some places in the semi arid regions, GI has been used to augment the groundwater sources. Many large cities are finding it difficult to implement this concept due to available land shortages. Good discussion!

I am not sure if this will be of any help, but we have found that Western and Japanese marathoners have a vertical oscillation 50% greater than East African marathoners. East Africans are known to consume less oxygen than Westerners while running. We believe this is due to their smaller vertical oscillation. The vertical oscillation of Western and Japanese marathoners adds an additional 2.48 miles to their marathon.

Dear Jack Baxter,

If the condition is to find experiments suitable to be conducted in a remote way, maybe you can prioritize online questionaires. You can search through academic sites such as Springer, Science Research, Google Scholar, Academia.edu. Obviously I suggest to do your search through this platform, in my experience I have got interesting outcomes.

Best,

Pía

Silvia Marchesi Thank you very much, well I have not developed a model yet, however I am really interested in the intestinal permeability of critically ill patients and ways of reducing it. I also agree with you with the microbiota part... I believe that bacterial metabolization is key for the effects of many interventions (particularly in nutrition). Thanks again and good luck to you too

@Back Tomas, thank you for the article.

Julie Barns - Thank you for your question. I think you need to develop a curriculum with specific learning outcomes. You need to see how many years or blocks are required in order to graduate students? And if these years are allocated into phases, what are the educational objectives of each period? . The attached website covers several differentiation approaches that you may use. You might need to learn more about the construction of a curriculum.

Hi jan,

Thanks for your answers. Many interesting points there. As far as I am aware there is no scientific evidence to suggest there has been an increase in sharks on the GBR. With an average daily range of around 10 km 2 for the Blacktip Reef Shark, or more for many other sharks, it is likely that local dive operators will also have seen a corresponding increase at their local dive

Hello Kenedy. I have a conference paper about EMC regulations that doesn't exactly answer your question but maybe can somehow help you: If you are not able to download it, I can send you. Good luck!

after you have spun your sample and saved the supernatant, are you loading the sample directly into a gel? You should mix your sample with 2x, 4x, or 6x sample buffer with betamercaptoethanol (BME) and heat to 70 degrees for 10 min or 95 degrees for 5 min. Then load this into your gel. The amount of BME that you add depends upon which form of BME you are using and the amount of protein that your supernatant contains.

You asked about the validity and reliability. These are the critical points. If you chose your subject from very dissimilar groups and settings there is a greater chance to get reliable data as well as external validity which is important for researcher who want to repeat the experiment. Check this out if it gives you advice: https://pdfs.semanticscholar.org/6462/54a1698a66aacb6eceb66c126309c3311997.pdf

Rather than use the USEPA standards, use them as a starting point. Then, if you can find an area in the US (or other country (developed?) where there are similar water uses look at the State standards. At least in the US, State's can have more restrictive standards. For example, in some areas, there is a significant subsistence consumption of fish. Locally, the WQS may be more restrictive because the bioaccumulative chemicals have a greater impact when more fish are eaten. Often, nationwide concerns (politics) may trump local needs and this will be reflected in Standards.

Dear Cedric,

You got multitude of stellar advice, so follow it. I wanted to put my five cents of experience in here. I had at least several cases that I was unable to repeat my own crystallization conditions and published one or two papers from a single crystal ever obtained. Science not suppose to be this way, but, what the heck, our knowledge of protein folding, behavior, conformational space, dynamic coupling with solvent and thermodynamic behavior (despite several Nobel prizes) is very limited. Do not give up easily because if something crystallized once, it is very likely to do it again, but possibly in other conditions.

Cheers,

Bog

While this may not be exactly what you are looking for....I have found it effective to eliminate as much division between fisheries researchers and managers as possible. I was able to do this in previous roles as a director of fisheries management agencies where I had both fisheries managers and fisheries researchers (scientists) working for me. Traditionally the managers and researchers were separated administratively and even physically. I eliminated these distinctions as much as possible and had them working together, administratively and physically. The result was an integration of science into the management of fisheries in a more complete and effective way than had been possible previously. The science evolved as needed. We had better science (well grounded and practical) and better management as a result.

Maybe spending days and nights studying literature and doing experiments is their form of recreation. For some people there is no distinction between vocation and avocation.

You are determining, in effect, whether the results are replicable with a larger or different data base. Nothing wrong with that, as long as you make it clear that this is what you are doing. The respectable goals of replication studies are confirmation and increased support for generalization.

**sorry i'm don't include religion in my life..

There is one Fourier transform only, that's mathematics (see textbook or Wikipedia).

When programming a discrete transform, you make many choices.

Instead of an integral from - infinity to +infinity you limit the scope. To avoid unwanted border effects, you filter your analysis window (weighting, convoluting...). Then you discretise quantify, that's a number of things different from the single mathematical object called a Fourier transform.

This is true for discrete cosine transform, wavelet transform, etc.

You will find this described in classical Signal Processing textbooks from the years 1980 to today, no need of the latest, it's old and well-known by the Ancients (LOL, sometimes knowledge gets assumed, and then forgotten, and discovered again)

Hello Christopher Brooke ,

If you have missing values in your data set, you have 2 choices before you run the clustering process. First choice is that you can delete rows, which have missing value, from dataset. And the second one is you can use any missing value estimation method. You can find different estimation methods about missing values. Such as: replace with mean, replace with mode, replice with median, etc. So if you don't want remove missing rows, you should specify an estimation method and apply your dataset. And then run k-means or any other clustering algorithm.

Best regards.

I suggest adding “length of visit per angler” to your formula and I think you may have all you need (get this by survey on site, survey cards, sample of anglers, etc) depending on what you want to do with the index results. The reason I suggest this is that if the population of target catachable species/sizes is high to start with, the length of visit to reach a “limit” per angler may be short (less pressure), but as populations of target species/sizes decrease, anglers may/will extend the length of visit (more pressure). If the target size/species is already low in abundance and anglers generally stay an entire day per visit regardless of fish abundance, then your current formula for pressure may be all you need to give a reasonable rough relative index, depending on what you want to do with that index. A simple way to compute CPUE is all you need if all you need is a simple solution.

I do agree with our colleague Adil Othman Abdullah .

Emad

Sounds like you would be using a mixed method for your research.

I agree with Mohamed, in that you have starting questions that will guide your lit. review. As you conduct the review you might also find questions that may be pertinent to your upcoming research. Keep a watchful eye as you go through the literature.

Dear Dr. Sikandar Hayat Khan , thanks for asking this question. Recreational cyborgs already exist, though at a limi scale. Humans have improved our abilities through our integration with technology right from the time when we started making and using tools. From abstick to microchips, it is positive thing and will be good for humans.

I think MATPOWER manual shows brief derivation, and explains the H & B matrices. search the document for Linear shift factors, PTDF: power transfer distribution factors, page 33/205 of the latest manual.

What type of contamination are you seeing? Bacterial? Fungal?

If you are not sure, try adding broad spectrum antibiotics (pen and Strep) and amphotericin B to the solution.

Thank you. Cost is a variable expressing the cost of a trip to the natural area, post_ER is a dummy variable expressing whether individual is surveyed before or after the ecological restoration. The aim of the model is to determine if restoration changed the demand curve (inferred from cost).

So, I understand that if post_ER is not interacting with cost, the demand curve of natural area is not influenced by ecological restoration, right?

Hi Francesca,

You may search at Sigma Aldrich website. The chitosan available in low, medium and high molecular weight. You may choose either one. Same goes to Hyaluronic acid. For Glycerophosphate, you may search for beta-Glycerophosphate disodium salt hydrate or Glycerol 2-phosphate disodium salt hydrate. I hope this will help you.

You can divide the areas in different stratas based on different levels of tourism and then compare these stratas in terms of biodiversity. Of course also keep a control strata

Thank you sir

So is this a wound healing model?

I would imagine that keratinocytes are not happy being exposed to air. Are they at least kept damp with diluted serum or plasma?

Maybe the glob you are seeing is crosslinked keratin made by the cells that couldn't survive the air exposure.

If you are not familiar with APDL or scripting in APDL, Your best choice will be a parametric FEA in Workbench. You can use either Spaceclaim or Solidworks for modelling your geoemtry (I explained the methodology usign Solidworks here) . You need to locate your part that needs to be rotated with a plane. Once you created geometry, call your geometry in Designmodeler. In workbench, click View-Properties. Then click the Geometry Icon. On the right hand side you will see the properties associated with your Geometry. Make sure "Parameter Key" is blank that enables importing all the dimensions from Soliworks to designmodeler. Open your DesignModeler and click Generate icon. Then Click your Geometry in the tree. After you did this you will be able to see all the dimensions imported from Soliworks in 'Detail View'. Find the dimension related to the plane you already defined in Solidworks and sellect it as parameter by clicking the check box on the left side of the dimension. Now, in workbench you see that the 'Parameter Set' is shown up. Double click it and then you will be able to change your prameter .there manually Changing this parameter lead to change your Geometry in Solidworks since ANSYS is linked with Solidworks. The geometry that you just imported can be used in any type of analysis. You can setup your analysis they way you want first and then create a design point in workbecnh to perform analyses on different angles you are intrested in. Also you can change your parameter with Python programing in workbench and save your result either in Excel or export as text file for each analysis. I have a lot of appreciation for APDL, However, things can be done a lot easier and fastere with Workbench.

John,

You could set the WTP question similarly as in the original survey. In addition to that, you would need to determine how the water quality parameters (as analyzed in the original study) changed over time in that water basin. This would include current water quality lab analysis and questions in the new survey (quality change as perceived by respondents). You could also add questions related to the perceived economic impact during the time since the original survey. However, most of information of economic impact will come from sources other than the survey, for example IMPLAN (direct, indirect, and induced economic impacts) or Census data. After completing the survey, you would link current WTP responses with water quality change over time and economic impact over time and determine how they affected WTP estimates (increased, lowered, or stayed the same) in addition to other variables (including those in the original survey). I hope this helps.

"Contact with still water, most often through swimming, was investigated in 19 studies (Fig 3). In 17 of these studies, swimming was related to an increased risk of infection with odds ratios (ORs) ranging from 1.5 to 87.0."

You could find more details in the attached file.

Hi Jamie,

not exclusively for triathletes, but for cycling.

Should be mentioned that half of population in the study where triathletes. Hope it helps.

I agree with Luis. I think that nature and culture tourism will continue to increase.

Europe will again be one of the most popular tourism destinations. I also think that the interest to far eastern coutries will be continue. In the Middle East, the situation does not seem to change much.

The number of Russian tourists coming to Turkey will be increased again. However, this situation became very sensitive. It can be shaped at any time according to the political relationships.

Hi everyone, 

 if you have another paper on this topic please send to me..

I researched the impact of standards in fruit production. (GLOBALGAP, EUROGAP). The most important thing is to determine the position of the input attributes of determining the start of the implementation of standards. Measure the difference between input and output. The attributes you have to define itself.

Dear Karean, 

I think its   relevant to the topic 

 1-The heritage management experience of Manx National Heritage (MNH) in the Isle of Man offers a practical case study

2- The Green State Parks Initiative: Utilizing Pennsylvania State Parks as a Case Study

Yes, there is. Most times students with disabilities are not supported by their peers or the institution is enabling their participation in recreational activities. These include access to and from the venues. 

Many thanks,

hello smith, 

if you try to find out the social value of closing a public park instead of other use, that mean it become hamper as usual daily use of this space and satisfied users. it really hard job to determine the value, but you can measure another way, like if the inhabitant could not able to use, that mean may be go through our public place/space/park/shopping, etc. and that result tends to their expense how they prefer to use to get it. and also you assess their satisfaction level after open that park. thanks.

Dirk's answer is touches very interesting points. I would add (and stress) the importance of the "catch and release" practice, especially in big game fishing. The promotion and diffusion of C&R practice is a keypoint for conservation of recreational fisheries stocks. Of course there are other important additional measures, such as, for instance, the use of circle hooks for minimising the damage of fish mouth. Moreover, recreational fishing activities should be monitored by fisheries biologists, who may take advantage of recreational fishing to gather morphological data, tag fishes, collect tissue samples for DNA analyses, etc.

Ciao

Thank you Joan.

Both approaches can be used. Approaches are different. But I suggest you to use travel cost method but again this depends on the objective of the study and literature can guide you better

Dear Slobodan, many thanks indeed for your answer but the data I'm looking for are not included in the file you sent me.

Best wishes!
