Answer
We have now had over 30 years of doom-mongering about so-called AGW and yet the effects cannot be measured against the natural rebound from the LIA (that destroyed many countries for centuries). Far more important is to develop strategies to mitigate any effects of climate change, e.g. sea-walls and reflective houses. The population of the world will not develop on unreliable power sources.
Ultimately, fusion must be the goal, but that remains decades away.

Non-renewable nature and environmental pollution toward the climatic changes are some disadvantages of fossil fuels (oil, natural gas and coal).
Hydrogen as a zero-emission fuel is a good solution to avoid the pollution. Ability of production of hydrogen fuel from the most available renewable energy, solar power (power to electrolyze) is a major encouraging point.
Trapping the countries in prize controlling authorities (OPEC) is another important reason to turn the hydrogen fuel.
However, risk of storage and handling is a major issue to be addressed when hydrogen is used as a fuel for general use.
I would like to discuss the ability of current technology for the production/use hydrogen (as a alternative for fossil fuel) for general needs.

How should we define the end of a local endemic?

Should territory wide screening of asymptomatic people be done before declaring the end of endemic?
Relevant answer
Answer
The SARS-CoV-2 (Covid-19) coronavirus pandemic is a global epidemic. On a global scale, the state of the pandemic in March 2020 was announced by the World Health Organization. Therefore, this organization could declare the end of the pandemic. On the other hand, the end of the epidemic on a regional, national or local scale can be announced by national central institutions of the health care system, including the ministries of health, in agreement with the government. In order to be able to declare the end of the epidemic on a national, regional or local scale, it is necessary to have a relatively large decrease in the number of new coronavirus infections, a decrease in the number of people seriously ill with Covid-19 disease and deaths caused by this disease. The decrease in Coronavirus infections and in sick people should be sustained in a longer period, i.e. min. several months, taking into account the periods of possible occurrence of subsequent epidemic waves caused by new variants of the Coronavirus and occurring in other regions of the world. In addition, an important factor that may be taken into account in the event of declaring the end of a pandemic on a global scale or an epidemic on a regional scale will be the level of vaccination of citizens with highly effective vaccines against Coronavirus and the level of social, collective immunity of the society achieved thanks to these vaccines.

In my opinion, sensitive personal data concerning individual users who set up profiles, collected on social media portals, are not fully secure. This is confirmed by the occurrence of data leaks, data theft by cybercriminals.
In connection with the above, the issue of information security on the Internet is becoming an increasingly global problem and therefore, in the global approach, institutions and security systems for the transfer of information on the Internet should be developed. The security of information on the Internet can refer to many aspects of data security both at the level of central state institutions and international organizations as well as the security of personal data of individual citizens, sensitive data of citizens collected on various websites, including social media portals.
The improvement of risk management and information security systems at the supranational level is also a key issue. Technological companies managing social media portals on the one hand try to improve data security systems about users setting up accounts on social media portals. On the other hand, it is also important to cooperate with key, central data security institutions on the Internet that operate transnational. This is important from the point of view of improving information security systems on the Internet in order to limit the possibility of using social media portals by cybercriminals operating transnational, using various social engineering techniques.

In hereditary neuropathy, "uniform conduction block" was once thought to be a characteristic in contrast to "non-uniform conduction block". Uniform conduction block is characterized by conduction block without any temporal dispersion. Now this is only seen CMT 1A hereditary neuropathy. Non-uniform conduction block is seen in other hereditary neuropathies and acquired demyelinating neuropathy. In the recent years, uniform conduction block is also observed in "axonal form of GBS" (AMAN and AMSAN), Some called this "axonal conduction block". This is misnomer.

AI Safety Issues can be categorized into five main classes including "Safe Exploration", "Scalable oversight", Avoiding “reward hacking” and “wire heading”, "Avoiding negative side effects" and "Robustness to distributional shift" (Amodei et al. (2016). Concrete Problems in AI Safety).
Can we categorize safety assurance of Evolutionary Optimisation Algorithms (e.g. Genetic Algorithm) as Safe Exploration?
Is there any approach for quantitative safety evaluation of such algorithms?
Thanks for your time and consideration.

I'd say these are classes to categorize the safety issues, not algorithms or families of algorithms.
For safety assurance, you'd need to address all issues relevant to your application.
Although safe exploration might be most important for Evolutionary Optimisation Algorithms, you'd still want to also avoid negative side effects.

I am currently working on a mixed refrigerant LNG cycle. There are total four components of the mixed refrigerant such as methane, ethane, propane, butane. When I have started doing the safety analysis (HIRA) of components such as compressor, heat exchangers, I find out that in the safety data sheets few of the data are not available for mixed refrigerants.
How I can do the inherent safety analysis of mixed refrigerant cycle, is there any mixing rule available or I should make some assumption, or I should give priority to any specific component of the mixed refrigerant and do the safety analysis.
It will be very kind of you if you can manage some time and give me your valuable feedback.
Best regards,
Rasel
Relevant answer
Answer
For a quick first check I would recommend contacting your equipment manufacturer. For their own development and research I am sure that they have such analyses on the shelf. If you are a student, you may still be able to obtain that information from a supplier, or contact someone in the LNG industry. That is not any type of proprietary knowledge, and all Safety Professionals are happy to share anything that will promote safer operations and understanding.
From a chemical perspective you really can look at each component individually in terms of safety. The negative effects are usually additive. That is, the addition of nitrogen, argon, or helium doesn't do a lot to mitigate the potential effect from a release of the flammable components, and each of them will have the same thermal operating envelope in the mixture as they do individually.

A correct interpretation of reliability analysis is determinative for researchers and industrial developers to refine their design and also prepare proper maintenance scheduling and safety analysis. However, I still see that many designers prefer to use classical safety factors instead of reliability analysis techniques. what's your sense about this.
For example, imagine that you are going to buy a bearing and I say you this bearing's reliability is 94% for the expected life of 5 years. it means that if you test 100 bearings under normal performance, almost 6 of them should fail after 5 years. does this analysis makes sense for you in your research and development?
and if the answer is yes, how do you use the outcome of reliability analysis in your research area. the answer is important for me because I am going to start developing commercial software for reliability analysis and it is important to see what are the expectations of experts from the reliability analysis methods.

Answer
Biological effects of UV radiation (e.g., to the eye and skin) are limited when receiving direct exposure. UVC radiation produces no toxic byproducts (including air emissions and volatile compounds), so you can safely enter the room when the system does not emit UVC (including soon after switched off). This is different from activation (production of radioactivity in materials) following exposure to some types of ionizing radiation such as neutrons.

There is also a debate on the differences of OSN, social media websites, social media portals and similar others. There are similarities in them but different researchers used these terms without any standardization.
Moving away from the debate of "user of correct term", I believe users have share already a lot on the OSNs and I am compelled to say that at individual level we have lost the battle of privacy against the giants such as Facebook and Google. They know and remember much more than we do. However, what is left behind is to preserve privacy of an individual from being violated by "Script kiddies" and a tech savvy guy(s). We need to raise awareness among the users based on this point.
The other point you have mentioned was about use of users' data for marketing purpose. Well, that was purpose of OSNs, otherwise, how will they gather revenue for their businesses. What we, as researchers, should look into how to improve and make their terms and conditions users' friendly so that users' may read them before accepting them. I must say only the most informed users will read the terms as their needs to use an OSN is much more higher than their perceived importance of privacy :)
I would love to discuss more, and even work if you have something in mind to initiate.
Cheers,
Ali

New question:
Another relevant question is, how to test the structural model invariance? e.g. I found that safety climate predicts physical injuries in the previous work, and I want to test this relationship based on two samples.
Yuting updated on May 22
_______________________________________________
Hi,
I am in the process of testing a safety climate model I built before based on a new dataset from other countries. I just started to look at the measurement invariance, which tests whether a different sample behaves in a similar way based on the same measurement "structure".
I feel a little confused, given the fact that different samples may behave differently. For example, one factor can be measured by six questions based sample 1, while only 5 questions can significantly measure the factor based on sample 2. My question is, we know that the measurement model can be different, why we still test measurement invariance? can we just propose two different measurement models based on two samples, rather than test the same model based on two samples?
Thanks.

I accidently stepped on a knotted biohazard bag (which was kept on the floor for some reason) and got some of the liquid on my shoe, socks and skin of my foot.
I work with HCMV, HBV and Zika. However each biohazard bag contains like 500 ml of bleach in which microtips used to handle virus samples were discarded. So the bleach to virus ratio is pretty high.
I doubt I'm in any danger but just wanted to know for sure. I've been spraying my foot with ethanol for now.
Relevant answer
Answer
If your personal protective equipment (PPE) was in place, no puncture has occurred and the biohazard bag was sealed properly (assuming that all sharp materials was disposed into a safe container), no harm should come. The best thing to do in case of spillage or accidents is not to panic but follow the safety guidelines which should also be displayed as an SOP inside your laboratory (link below) and inform the biosafety officer or the laboratory in-charge. The contact time for chlorine-based disinfectants varies from 10-60 minutes. However, the surface of the discard bags prior to removal from the cabinet are also usually cleansed with suitable non-corrosive solutions. If some uncertainty still persists, its best to get yourself examined.
Here are some reading materials which might help.
Watch your step next time! Stay safe.

Hello everyone,
There is too little information on Blebistatin safety datasheet about disposal, so I would like to know from anyone who has already used blebbistatin how you dealt with the residues. What is the proper procedure to discard it?
Thank you!
Relevant answer
Answer
In the Sigma SDS I found the followings:
13. DISPOSAL CONSIDERATIONS 13.1 Waste treatment methods
Product: Offer surplus and non-recyclable solutions to a licensed disposal company. Contact a licensed professional waste disposal service to dispose of this material. Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber.
Contaminated packaging: Dispose of as unused product.
TOCRIS SDS:
13. DISPOSAL CONSIDERATIONS 13.1 Waste treatment methods
Product: Transfer to a suitable container and arrange for collection by specialized disposal company in accordance with National legislation.
Contaminated packaging: Dispose of in a regulated landfill site or other method for hazardous or toxic wastes in accordance with National legislation.
Selleckchem SDS:
13. DISPOSAL CONSIDERATIONS 13.1 Waste treatment methods
Product: Dispose substance in accordance with prevailing country, federal, state and local regulations.
Contaminated packaging: Conduct recycling or disposal in accordance with prevailing country, federal, state and local regulations.
FYI: blebbistatin is photosensitive and quite unstable in aqueous environment. So it may happen that by the time you discard it, it will not be an active myosin inhibitor any more.

If the safety imput from culture and climate are at odds will this increase the risk of an accident.
Relevant answer
Answer
Interesting question.
Some clarifications are in order before attempting a complete answer.
I suppose you mean *congruent* and that *safety inputs* imply risk avoidance, hazard reduction and the like. A first issue is that congruent has a very clear meaning in mathematics (e.g., geometry) but may not apply to this question because the two aspects you are concerned with (culture and climate) are vague. Intuitively, culture and climate are correlated in some ways. Both climate and culture have many dimensions hence we need more specificity on these. I would begin as follows. Assume that climate signals (e.g., temperature changes ) affect some specific aspect of culture (e.g., aesthetics) either directly or indirectly and "cause" a change. If so, the problem can be formulated via correlations (not merely statistical) and other techniques including qualitative methods. Does this help frame the question a bit more precisely?

Paolo

Germany has set some HBM-I values for phthalates. The HBM-I-value represents the concentration of a substance in human biological material below which – according to the knowledge and judgement of the HBM Commission – there is no risk for adverse health effects and, consequently, no need for action (https://www.umweltbundesamt.de/en/topics/health/commissions-working-groups/human-biomonitoring-commission/reference-hbm-values). There have also been some Biomonitoring Equivalents proposed e.g. for DEHP and DINP.

As mentioned by Sebastian safety issues in working with glove boxes is definitely with slight over pressure.
Being also responsible for chemical lab safety I guess it might be a misunderstanding of your Health & Safety department because chemical labs where our glove boxes are being used, of course run in under pressure environment avoiding gases etc. reach the offices and floors.

What can you say about safety aspects of Industry 4.0.
Which types of issues should be given special attention?
Relevant answer
Answer
Dear Adam,
It is really a nice and interesting topic you discussed.
To answer the question, let's brief the meaning of Industry 4.0.
Industry 4.0 promotes more extensive computerization based on new technologies including cyber-physical systems and the Internet of Things. Intelligence and an ability to communicate are being distributed down to individual machines and components. The goal is the creation of the “Smart Factory,” which uses technology to deliver greater adaptability, resource efficiency and ergonomics, as well as better information exchange among customers and business partners.
Now, coming to the point of safety aspects of the industries. (i) Sensor-based technology helps in automatic detection of accidents or health problems of the workers at work; (ii) Video surveillance system provides an excellent control on the environment that eventually helps in safety of workers; (iii) With the help of IoT devices and hybrid solutions, one can monitor and send across safety information which includes an employee’s biometrics. This, as a result, will help companies reduce their insurance cost through enhancing worksite safety in a smart and effective manner. Since workplace safety is a top concern, development and collaboration of such IoT technologies will be critical for companies to invest in [4]. Apart from this, you may also find some useful references/links given below that would help you extensively.

Answer
The solvents which have slightly higher boiling points must be preferbly used (DMF, DEF, DMSO, DMA etc even ethanol can be used) instead of low bioiling points solvents (Chloroform, acetone, acetates etc). But main thing which should be be focussed is ratio of organic solvent is to water, try a mixature instead of pure organic solvents. The Organic counterpart must be in smaller ratio or you can vary the two accordingly in optimization of reaction conditions.
Caution: The most important thing which must be kept in mind is never go more than 35 ml volume of reaction mixture otherwise mishappening can be happen.
