I am trying to conceptualize a topic on radon monitoring in the Philippines and I am still thinking if using CR-39 detector is enough or should I incorporate the usage of the RAD7 real-time monitor for radon? Thank you.
Relevant answer
Answer
yes. But it depensd how long you want measure Radon concentrations...for very short time, 1-2 weeksm the active monitor is ok, but for a long time, some months, to avoid the instruments shut down or other problems...
Normally I use the active monitor to find hot-spot or to check the radon concentration in a short time ( 1 week for example) to verify the remediation activities from high Radon concentrations.

Assalam u alaikum and Hello everyone,
I am trying to prepare an inclinometer for slope deformation measurement by sticking strain gauges (type: GFLAB-3-70-3LJC-F) sensors around a PVC pipe as shown in attached fig. But I am not sure about the strain gauge sensor could provide continuous reading for monitoring purposes or not.
Eagerly waiting for your suggestions
Relevant answer
Answer
To answer your headline question, yes. Providing that you do not deform the gauge beyond the strain limit (3% or 30000×10-6 strain) at any point it should be suitable. The gauge you have chosen claims to compensate for heating during deformation and tightening effects, which will also be important if you are repeatedly taking measurements over time.
Regarding your pictured setup however I have some questions. These are not critiques, just observations and considerations:
I assume you are looking to measure a change in angle of the slope relative the horizontal axis (assuming there is no deflection within the slope) and not the deflection within the slope using this setup? If you are looking to measure the former, then it is suitable providing the pipe is not stiff enough to significantly deflect the slope during the measurement. If it is the latter, then the setup is only suitable if two of these three variables are fixed: location of force, degree of force and angle of force relative to the slope .
How are you deciding the dimensions of the PVC pipe and the placement of your gauges?
Why not use a strip of PVC? Is it due to concerns about exceeding the gauges strain limit so you want increased stiffness?

How should an efficient and high-tech monitoring of environmental pollution levels be built?
In July 2022, one of the largest rivers in Poland was polluted by a discharge of warm, saline, highly oxidised water and possibly also by still unknown toxins.
Almost the entire river biosphere died out. Now (August 2022), the rotting remains of dead fish have caused secondary decay processes and a decrease in oxygen. Previously, so-called golden algae, which are harmful to the biosphere and form strong blooms in warm and saline water, have also developed. This is one of the biggest ecological disasters in Poland. The strangest thing is that anglers had already signalled at the end of June that the ecosystem of the Oder River had been severely disrupted by unknown substances released into the river. However, the services responsible and subordinate to the government, the company managing the state of rivers in Poland, i.e. Wody Polskie (Polish Water), started to do anything about it to save the river's ecosystem only in mid-August 2022.
Before that, anglers had already managed to catch tens of tonnes of dead fish.
Now many citizens are trying to answer questions:
Why did the river's environmental monitoring system not work?
Why have the institutions of the state acted with such a long delay when it comes to saving the river's ecosystem?
But this is just one of many examples of environmental disasters still occurring in various parts of the world.
In view of the above, I address the following questions to the esteemed community of scientists and researchers:
How should an efficient and high-tech monitoring of environmental pollution levels be built?
How should an effective monitoring of the state of the environment be developed in order to significantly prevent still occurring environmental disasters?
How should an efficient monitoring of the state of the environment be built, including monitoring of the level of pollution of the terrestrial or aquatic environment (rivers, lakes, seas, oceans)?
How should an efficient analytical system for the state of the terrestrial and/or aquatic environment be built?
What ICT information technologies, Internet, Industry 4.0, satellite, etc. could be useful to improve environmental condition monitoring?
How should an efficient system of systemic environmental risk management be built?
What do you think about this topic?

Hello Dariusz: Just this morning I read about this episode in the Los Angeles Times. The article was written from the point of view of German environmental agencies and a political exchange with the Polish government. The impression I got was that the source of the toxins and a reasonable list of the toxins has not yet been determined. If that's true, then, the first order of business is the identification of the problem and its source(s). It sounded like the problem is a complex one. Polish and German scientists must been collaborating before June. What do those folks have to say? Best regards, Jim Des Lauriers

VWP are generally used for ipezometric recording in soil, landfill, large concrete works such as dams.
A colleague of mine wants to us them to monitor water table change, instead of more simple tools (such as conventional divers).
Any idea of added value?
Relevant answer
Answer
I have not used VWP. This might be an alternative to consider. For normal well monitoring of water level, pressure transducers seem to work well. The vented type includes a wire the length of the deepest measurement depth, and does not need to be corrected for barometric pressure. The unvented transducer is self contained, and could be lowered any reasonable distance, but the data needs to be corrected for barometric pressure. Both transducers I am familiar with has an internal battery and data logger that can be programmed for desired frequency of readings. In use for stream or high salinity areas, the membrane can be fouled by sediment or minersl accumulations, so some periodic maintenance or repair with recalibration of depth may be needed in those circumstances. Typically thousands of readings could be collected with the data logger, but I typically took readings every 5-15 minutes, and downloaded and check function about monthly. In a situation with perched water table, one would need two boreholes to appropriate depth, and each with a transducer.

Internet Security Protocols
To provide the security to this internet various protocols have been used like SSL (Secure Socket Layer), TLS (Transport Layer Security), etc. Various Internet Security Protocols. Given below are the various protocols: Start Your Free Software Development Course. Web development, programming languages, Software testing & others. 1. SSL Protocol. SSL Protocol stands for Secure Socket Layer protocol, which is an internet security protocol used for exchanging the information between a web browser and a web server in a secure manner. It provides two basic security services like authentication and confidentiality. ... Encryption and digital signature format used in SHTTP have the origins in the PEM (Privacy Enhanced Mail) protocol.
_____
In computing, Internet Protocol Security (IPsec) is a secure network protocol suite that authenticates and encrypts packets of data to provide secure encrypted communication between two computers over an Internet Protocol network. It is used in virtual private networks (VPNs).
IPsec includes protocols for establishing mutual authentication between agents at the beginning of a session and negotiation of cryptographic keys to use during the session. IPsec can protect data flows between a pair of hosts (host-to-host), between a pair of security gateways (network-to-network), or between a security gateway and a host (network-to-host).[1] IPsec uses cryptographic security services to protect communications over Internet Protocol (IP) networks. It supports network-level peer authentication, data origin authentication, data integrity, data confidentiality (encryption), and replay protection (protection from replay attacks).
The initial IPv4 suite was developed with few security provisions. As a part of the IPv4 enhancement, IPsec is a layer 3 OSI model or internet layer end-to-end security scheme. In contrast, while some other Internet security systems in widespread use operate above the network layer, such as Transport Layer Security (TLS) that operates above the transport layer and Secure Shell (SSH) that operates at the application layer, IPsec can automatically secure applications at the internet layer.

I read many articles on the use of the handheld GreenSeeker to measure the greenness of crop canopy cover and N uptake under field conditions. But I couldn't catch articles that deal with the same issue for pot experiments.
Can I use GreenSeeker for measuring the NDVI of crops grown in pots under greenhouse conditions?
Relevant answer
Answer
The GreenSeeker™ handheld sensor is an easy-to-use optical sensor that instantly measures plant health and vigor in terms of NDVI readings. The sensor emits brief bursts of red and infrared light, then measures the amount of each type of light reflected back from the plant. Trimble GreenSeeker handheld crop sensor is an affordable, easy-to-use measurement device to assess the health — or vigor — of a crop in order to make better nutrient management decisions on your farm.Use the GreenSeeker handheld to instantly take a reading of your crop’s health. Readings can be used to make non-subjective decisions regarding the amount of fertilizer to be applied to your crop, resulting in more efficient use of fertilizer — a benefit to your bottom line and the environment.The optimal range that the sensor should be used at is anywhere from 24 to 48 inches or 60 to 120 centimeters above the crop canopy.At the beginning of the season, the NDVI index helps to understand how the plant has survived through the winter.
arious vegetation indices are often used in precision farming, and the NDVI is the most popular one. It allows you to monitor fields and crops at any point of the globe using satellite images. Here is a simple explanation of what the NDVI vegetation index is and how to use it for field analysis. 1 1 If the NDVI is lower than 0.15, most probably all the plants died in this part of the field. ...
2 2 0.15−0.2 is also a low value. ...
3 3 0.2−0.3 is a relatively good value. ...
4 4 0.3−0.5 is a good value.
Healthy plant actively absorbs red light and reflects near infrared.
NDVI=(NIR-RED)/(NIR+RED)
1. -If the NDVI is lower than 0.15, most probably all the plants died in this part of the field. Typically, these figures correspond to plowed soil without any vegetation.
2.-0.15−0.2 is also a low value. This may indicate that plants started wintering in the early phenological phase, before tillering.
3.-0.2−0.3 is a relatively good value. Probably, the plants entered the tillering stage and have resumed vegetation.
4-0.3−0.5 is a good value. Nevertheless, you should keep in mind that high NDVI values can indicate that plants wintered at a late phenological stage. If the satellite image was taken before the resuming of vegetation, then it is necessary to analyze the zone after the resuming of the vegetation also.
5-Above 0.5 is an abnormal value for the post-wintering period. It is better to check this field zone yourself.

How can CRISPR/Cas delivery to the targeted cell be monitored in vivo and in vitro?
I read in one article that in vitro, it can be monitored by adding the antibiotic resistance gene to the plasmid. and after the delivery process by adding the antibiotic to the plat, we can be sure that survived cells took the plasmid which contains both CRISPR components and antibiotic resistance genes!
so is there a specific approach for monitoring the proper delivery in-vivo as I think the last method is not proper for in-vivo study??
Relevant answer
Answer
Antibiotic resistance genes are for selection or enrichment. You could use fluorescence reporter gene to label the CRISPR expressed cell either in vivo or in vitro. Those reporters could be delivered as fusion parter with CRISPR: eg. Cas9-GFP, or co-expressed with CRISPR: eg. Cas9-2A-GFP.

The main features of smart homes/buildings include real-time monitoring, remote control, safety from intruders, gas/fire alarm, and so on. Because sensitive and private information is managed within smart homes/buildings, security and privacy solutions must be put in place in order to protect users/businesses' data against violation attempts as well as to guarantee the provision of reliable services. To this end, rules—in the form of policies—associated with the smart home/building resources must be defined and correctly enforced by means of a robust framework for handling the huge amount of IoT data managed.

This work has presented an intelligent home automation system based on IoT technologies, cloud computing, and a machine learning algorithm. The home automation system allows remote and local control of the home via an Android-based mobile application. The system controls electrical home appliances, monitors environmental conditions through temperature, humidity, and light sensors, and ensures home security through a motion sensor and an IoT camera. The system makes intelligent decisions to automatically turn ON or OFF lights and allow the user to view a picture of the person captured by the camera and decide whether to save it. The system is scalable, and the application allows additional appliances with an extra configured point, simply named outlet in our work. Also, the mobile application uses a real-time cloud database to record data gathered. It also displays the trend of the readings graphically on the screen of the mobile application. These data can be analyzed and used for future prediction. The next phase of the work will be to use a dataset of several real-life images captured by the camera from the system or sourced from relevant datasets in the field of home automation and train a machine learning algorithm to classify them so that the system could differentiate between an intruder and the home occupants. Also, we plan to enhance the system such that the user will only receive captured images of an intruder, and other captured images will be saved in real-time into the cloud-based database of the system. This will remove the limitation on the encumbrance of a load of images on the mobile application. In addition, machine learning will also be used to enhance the PIR sensor’s performance to differentiate between an animal, the occupant, and an intruder. This will reduce the notification from the PIR sensor to the user. The machine learning algorithm will also be applied to classify detected images to work with several occupants and a larger data set of intruders.

Hello everyone,
We are setting up an EEG experiment using OpenSesame for purpose of stimulus presentation. EEG device we will use is Neuroelectrics Startstim 32 with NIC2 software to design protocols and monitor EEG/ERP signals. It is recommended to use labstreaming layer (LSL) to connect OpenSesame with NIC2. To completely set up our experiment we need to send triggers/markers during the experiment from OpenSesame to NIC2. 
I suppose that we need to do some coding by inline script items. Does anyone have experience with sending triggers from OpenSesame to any EEG device via LSL? If so, I would appreciate very much if someone could send a code that had been used with this purpose. If there isn’t a finished code/solution to share, does anybody have an idea how this could be resolved? I've searched throughout the web about LSL and opensesame and had not found adequate help for OpenSesame particularly, but I did find some codes for LSL and PsychoPy. Do you think that PsychoPy code would work in OpenSesame also (since both are written in Python)?

Hi all,
In my patch clamp rig we have a 'IR-1000 camera' set up to a 'bnc-video to VGA video converter' which is attached to a monitor, through a VGA cable.
This set up worked fine, but recently we get no signal in the monitor, not even in the test function. We tried replacing all the cables, the video converters, the monitor and the IR-1000 control, nothing worked. The camera is working, since we get the image when we plug the BNC-video cable directly into our old cctv monitors.
The lab member who previously used this rig said he had the same issue, but that the set-up started working again by itself after a while.
Has anyone had this type of issue before? Is there any way to resolve it? Or any ideas to why this must be happening?

Hi all,
In case anyone is going through a similar issue. I managed to recover the signal by changing the 'BNC-video to VGA video converter' to a DAGE-MTI supplied 'Composite to USB-C converter'. It is more expensive, but is working fine now.

Dear Eloise Hench,
My best guess is that HTR is an indicator for high temperature, since (especially these old) devices have an operational temperature range up to about 40-50°C usually, so I think if the temperature inside the anaerobic chamber exceeds this limit, the HTR light flashes.

how to conceptualize monitoring and evaluation based on compliance to occupational health and safety.
Relevant answer
Answer
Hi Ritah,
The answer to this is rather simple to describe, but more complex to implement, particularly the collection of the data. A simple approach is to identify the critical behaviors that must be followed and build them into an observational checklist. If used with a number of employees, you could report percentage compliance for each behavior or overall. This approach could be modified by first determining the importance of each behavior (e.g., crucial, important, or recommended) and building this into the analysis. Since you are dealing with a finite number of employees, the analyses will be simple descriptive statistics such as frequency counts and proportions (or percentages). I hope this is helpful.

Are there any monitoring technologies for predicting educational processes in universities?
Usually, monitoring processes in higher education institutions are aimed at identifying, analyzing and eliminating a particular problem. However, it is not possible to accurately predict the impact of the identified problem on subsequent activities. Our question focuses on technologies that allow us to measure, through what percentage or coefficient, the impact of the identified problem on future activities. If such technologies exist, then on the basis of what parameters or indicators are these percentage or coefficient relations formed?

Dear All.
I am working in LAA WiFi coexistence scenario. For my work, I need to calculate the Latency/Delay in a different way.
From my understanding, the way current solution is calculating the delay is that it is monitoring the time between the packet was first transmitted and last seen from the receiver's perspective. It is done in the FlowMonitor class where you calculate all the delay into delaysum and calculate the average delay.
Now, what I want to do is that, for every received packets, I want to set a timer when the packet is being generated and add with the individual delay values and calculate the avg delay. Now, as I am talking about the LAA-WiFi coexistence, I cannot make a solution that only works for Wi-Fi. So I have to solve this problem from the base, I mean, the Packet class.
Did anyone work in this problem before? Need some expert suggestions. And Thank you in advance for your kind assistance.

I am running the experiment where I am monitoring the OCP of steel in two different media (A & B) for a week and ran the Tafel experiment at the end of OCP.
Compared to medium B, medium A is showing more negative values of OCP and Ecorr of steel at the end of experiment. Is it right to conclude that the corrosion susceptibility of steel in medium A is relatively higher compared to medium B?
Relevant answer
Answer
Dear Dr. Sana Mirza ,
long-term change of corrosion potential (open-circuit potential) reflects a change in a corrosion system because the change in corrosion potential depends on the change in one or both of the anodic and cathodic reactions. For example, an increase in corrosion potential can be attributed to a decrease in the anodic reaction with the growth of a passive film or the increase in the cathodic reaction with an increase in dissolved oxygen. A decrease in corrosion potential can be attributed to an increase in the anodic reaction or a decrease in the cathodic reaction. The monitoring of corrosion potential is therefore often carried out (ISO 16429, 2004; JIS T 6002). For the test solution, saline, phosphate buffer saline, Ringer solution, culture medium, serum and artificial saliva are typically used. The corrosion potential of the specimen can be monitored against a reference electrode using an electrometer with high input impedance (1011 Ω ~ 1014 Ω) or a potentiostat.
For more details, please see the source: Monitoring of corrosion potential by S. Hiromoto, in Metals for Biomedical devices, 2010.
The most widely used electrochemical method of determining the corrosion rate is the Stern-Geary method which allows to evaluate the corrosion current (i corr), an essential parameter from which to derive the corrosion rate of the material in that particular environment.

I have to discuss an issue regarding relative humidity in Radon monitoring from soil gas. We are continuously monitoring Radon from soil (24/7) for the whole year. With the passage of time, our instruments are reading irregular values because of increasing levels of humidity. Desiccant like Anhydrous Calcium Sulphate (provide with RAD-7 instrument) is useful if we have to do sampling for a limited time and for long term monitoring this method is very expensive. A device like Drystik from Durridge Company is also available but its pump life is of one year. So, for a reliable and long-lasting solution what should have to do to improve our data acquisition and data quality?
Relevant answer
Answer
The moisture in the instrument can be controlled several ways that could be compatible with your measurement requirements.
  • Place the instrument in a controlled environment (a small enclosure that is exhausted and held at a temperature that ensures no condensation within the instrument)
  • Cool the sampling tube for moisture removal, then warm for analysis
  • Pull the sample through a porous tube that is annularly placed within a tube containing rock salt. Change out the annular tube on a regular basis so the salt can dry for reuse. Very simple and inexpensive.
  • Use a submersible diffusion barrier type detector as used for continuous water monitoring.
Any further suggestions requires knowing your sampling requirements and the intended accuracy to meet your experimental needs.

Hello,
I'm calculating the mode overlap between my Spot Size Converter (SSC) and an optical fiber (SMF-28, NA = 0.14) in Lumerical FDTD using the Mode Expansion Monitor and Linear DFT Monitor. At the same time, I'm comparing the result with the Mode Overlap Integral of SSC (fig is attached).
The difference value is too much (~20% of difference) and I would like to know if by using the Mode Expansion Monitor the mode overlap calculation is similar to the model attached. The model attached is found in many papers and to use it I simply export the E fields calculated by Lumerical (the SSC and optical fiber E field) and import them in matlab to calculate the Mode Overlap between the fields.
Does anyone know the difference and which would be more accurate?
Thank you.
Relevant answer
Answer
Taynara Oliveira - regarding the Lumerical article, as far as I can tell, they are calculating a 2-D overlap integral over the waveguide cross-section.
I believe there are some errors in the web page, for example using S rather than dS in the first overlap integral. Their approach using both E and H fields looks similar to an integral over contributions to the Poynting vector which I had not seen before. Google found references to its use with waveguides which are birefringent or chiral, and these may give you more background.
Lumerical reference A. W. Snyder and J. D. Love, "Optical Waveguide Theory". London: Kluwer Academic Publishers (1983).
Snyder and Love describe both vector treatments and scalar wave approximations for waveguide propagation. Chapter 20 begins with the vector results, but mostly deals in the weakly guiding limit, where it is sufficient to consider only the electric field components. They consider various Gaussian approximations (as suggested by David A. Ackerman) in some detail.
As I pointed out in my first response, and as David also states, with radial symmetry, it is possible to reduce the 2D overlap to 1-dimensional integrals, but it is essential to include the appropriate radial weighting.
Not including a radial weighting factor is a likely reason for your 20% discrepancy.
Attatched is a comparison of 1D and 2D overlap integrals for a Gaussian mode field, and a "top hat" illumination field.

I have built a membrane system using charmm gui. How can I know that the system is equilibrated after doing the equilibration steps? What are the values I should monitor to know?
Thanks
Relevant answer
Answer
You can check various properties of your system, such as pressure, temperature, radial distribution function, potential energy, distance between some atoms and so on. When you observe some equilibrium fluctuation behaviors then you can say it is a good starting point for equilibrium sampling.
However, when you are really experienced in the area of molecular simulations, you will find that this equilibrium assumption is actually never achieved in complex systems. The overwhelming local fluctuations in these heterogenous systems can never be truly equilibrated out unless infinite simulation time is employed, which is valid only from a theoretical prespective rather than an achievable goal in practice.
So, overall the answer to your question is simple. You can just monitor some quantities of interest to 'check' equliibrium, but whether that is useful remains an open question.

Hi everyone,
I'd like to inquire about the best method for monitoring the water level of a borehole with a depth of up to 400 meters. Although the depth of the boundary is unknown, it is assumed to be fractured diorite (upper) and diorite bedrock (lower). I've read about open standpipes and vibrating wire piezometers, but I'm concerned about their long-term reliability. It would be fantastic if you could contribute your practical ideas and opinions. I am open to ideas and eager to learn more from you. Thank you sincerely!
Best regards,
Raymond
Relevant answer
Answer
Hi Raymond,
400m is challenging but should work.
a pressure level sensor should work, if they are able to manufacture a 400m gauge wire.
I’ve worked a lot with these devices and they are quite durable. You can set up them for automatic monitoring. If you need a high failure safety, you can setup them in a array of 2 or 3.
if you are looking for manual monitoring devices, a contact gauge is a easy to use tool.
There are some other methods, like pneumatic level monitoring but I have no practical experience in terms of durability.
the diameter of the borehole should be at least 100mm with smooth edges.

Ventilation during adult cardiopulmonary resuscitation (CPR) is poorly understood. Therefore, guideline recommendations are limited. The use of waveform capnography is in part recommended to monitor frequency. Other ventilation measurements such as tidal volume or inspiratory pressure are not regularly obtained, especially when a bag-valve system is used. The use of new monitoring devices can improve guideline adherence and could lead to better understanding of ventilation during CPR. Different EMS systems have varying levels of training, equipment and resources during CPR of out-of-hospital cardiac arrest (OHCA) patients. To better understand the current state of ventilation monitoring during OHCA CPR researcher/practitioner feedback and international perspectives on this question are needed and very much appreciated.

Answer
SPC is a non-trivial business, above all when realizing that semiconductor device features have reached sub-nm sizes and the specifications are strongly demanding in terms of accuracy and repeatibility on single (12 in.) wafer, wafer-by-wafer in a batch, and across several successive batches.
A simple answer to your question is that the UCL and LCL are normally fixed as a multiple of the variance of a process (for the given characteristics under control), e.g. 3sigma. In any case, the two limits must stay within the window given by the spec, which are fixed by design. However, this answer is too simplistic. I suggest you to carefully read some detailed book on the SPC topic..

If you dis then you have your clone and you can propagate these cells dor further experimentation.
Another way is to use trypsinization rings to select the population of tour clones.

Hi, I would like to learn about monitoring macrophytes in rivers, lakes, and heavily modified water bodies. As much as I know, macrophytes are monitored in rivers and lakes, but they are not used as an indicator for ecological status in rivers. Different indicators are used to determine ecological status in rivers So should we monitor them in rivers? I think that it will bring extra costs to the project.
Relevant answer
Answer
Macrophytes are being monitored in both rivers and lakes in many EU countries that implement the Water Framework Directive. They are used as indicators of ecological status as they can reflect changes in the hydromorphology and nutrient content of lotic and lentic environments and are quite cheap to sample in streams and wadeable rivers.
Please note that macrophytes are a broad group of aquatic plants including not only angiosperms but also bryophytes, macroalgae and aquatic ferns. In high and mid-altitude streams rooted angiosperms are rare but bryophytes, ferns and charophytes are not uncommon. In lowland slow-flowing rivers, rooted or free-floating plants are usually more abundant and can form dense populations.
