Mouth and talk goes like the food and digestion, (my coinage.).
Of my understanding of Sharia, Sharia meant to be Safety and a device for Tommy Robinson. As Sharia is meant to be for safety and justice.
Anyway, I believe Tommy Robinsons concern should not be ignored, he has right of seeking safety and freedom to his freedom of speech.

How to reduce the risk of leakage of sensitive data of companies, enterprises and institutions that previously employees of these entities enter into ChatGPT?
How to reduce the risk of leakage of sensitive data of companies, enterprises and institutions, which previously employees of these entities enter into ChatGPT or other intelligent chatbots equipped with generative artificial intelligence technology in an attempt to facilitate their work?
Despite the training and updating of internal rules and regulations in many companies and enterprises regarding the proper use of intelligent chatbots, i.e., for example, the ChatGPT made available online by OpenAI and other similar intelligent applications that more technology companies are making available on the Internet, there are still situations where reckless employees enter sensitive data of the companies and enterprises where they are employed into these online tools. In such a situation, there is a high risk that the data and information entered into ChatGPT, Copilot or any other such chatbot may subsequently appear in a reply, an edited report, essay, article, etc. by this application on the smartphone, laptop, computer, etc. of another user of the said chatbot. In this way, another Internet user may accidentally or through a deliberate action of searching for specific data come into possession of particularly important, key, sensitive data for a business entity, public institution or financial institution, which may concern, for example, confidential strategic plans, i.e., information of great value to competitors or intelligence organizations of other countries. This kind of situation has already happened and occurred in some companies characterized by highly recognizable brands in specific markets for the sale of products or services. Such situations clearly indicate that it is necessary to improve internal procedures for data and information protection, improve issues of efficiency of data protection systems, early warning systems informing about the growing risk of loss of key company data, and improve systems for managing the risk of potential leakage of sensitive data and possible cybercriminal attack on internal company information systems. In addition, in parallel to improving the aforementioned systems that ensure a certain level of data and information security, internal regulations should be updated on an ongoing basis according to the scale of the risk, the development of new technologies and their implementation in the business entity, with regard to the issue of correct use by employees of chatbots available on the Internet. In parallel, training should be conducted, during which employees learn about both new opportunities and risks arising from the use of new applications and tools based on generative artificial intelligence technology made available on the Internet. Another solution to this problem may be to order the company to completely ban employees from using smart chatbots made available on the Internet. In such a situation, the company will be forced to create its own, operating as internal such applications and intelligent chatbots, which are not connected to the Internet and operate solely as integral modules of the company's internal information systems. This type of solution will probably involve the company incurring significant financial expenses as a result of creating its own such IT solutions. The costs can be significant and many small companies' financial barrier can be high. However, on the other hand, if the construction of internal IT systems equipped with their own intelligent chatbot solutions becomes an important element of competitive advantage over key direct competitors, the mentioned financial expenses will probably be considered in the category of financial resources allocated to investment and development projects that are important for the future of the company.
The key issues of opportunities and threats to the development of artificial intelligence technology are described in my article below:
OPPORTUNITIES AND THREATS TO THE DEVELOPMENT OF ARTIFICIAL INTELLIGENCE APPLICATIONS AND THE NEED FOR NORMATIVE REGULATION OF THIS DEVELOPMENT
In view of the above, I address the following question to the esteemed community of scientists and researchers:
How to reduce the risk of leakage of sensitive data of companies, enterprises and institutions, which employees of these entities previously input into ChatGPT or other intelligent chatbots equipped with generative artificial intelligence technology in an attempt to facilitate their work?
How do you mitigate the risk of leakage of sensitive data of companies, enterprises and institutions that previously employees of these entities enter into ChatGPT?

Has the current energy crisis, including rising fossil fuel and energy prices, increased the scale of public acceptance for building a nuclear power plant?
Nuclear power can be an important element in increasing the diversification of energy sources when other types of energy sources have been developed in the country. Among these other sources of energy types, many countries have traditional, dirty, emission-intensive fossil fuel-based energy sources and various types of environmentally and climatically clean renewable and emission-free energy sources developed mainly in recent years. Emission-free energy sources based on cold fusion and hydrogen power will be developed in the future. This is particularly important in view of the developing climate crisis generated by increasing civilisational greenhouse gas emissions and the accelerating process of global warming. In order to slow down the progressive process of global warming, it is necessary to carry out a full pro-climate transformation of the energy sector through the development of renewable and emission-free energy sources within the next few to a maximum of a dozen years. An alternative transition technology to achieve a fully carbon-free economy, including a carbon-free power sector, could be nuclear power. Nuclear power plants under construction today are much safer than those built a few decades ago. The use of modern technologies makes it possible to ensure a very high level of safety in the operation of nuclear power plants regardless of the action of various external factors, including, for example, the fall of a large aircraft on the power plant or ballistic missiles. In addition, it has been estimated that, given current fossil fuel prices, nuclear power could be several times cheaper than coal power. Research institutes analysing nuclear safety issues have estimated that the probability of an accident in a modern nuclear power plant is 1:40 million. By comparison, the probability of a person being struck by lightning is estimated at 1:300,000. Consequently, the scale of public acceptance for the construction of a nuclear power plant is increasing. This change is influenced by the above-mentioned issues of improving the safety of nuclear power operations and the current energy crisis.
And what does this issue look like in your country?
What are the key factors in changing the level of public acceptance for the construction of a nuclear power plant?
What is the role of the media and governmental socio-marketing campaigns in changing the general public awareness of the issue?
Has the current energy crisis, including rising fossil fuel and energy prices, increased the scale of public acceptance for the construction of a nuclear power plant?

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.

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.

Environmental Management extents to sustainability issues in value and supply chains. and so, environmental impacts arising from organisations and their concomitant impacts remains a worry since organisations produce more impacts than individual emissions. To help in discussing sustainability initiatives, integration and their impacts, it is pertinent to understand the extent of incorporation in different countries including the system that have been adopted. To help in this discussion, the guide are as follows:
1. how knowledgeable are you on sustainability incorporation in value chains?
2. how far have your country's organisation fared with such implementation?
3. what are the reasons/ benefits for sustainability in supply chains?
4. Are there challenges in embedding sustainability in supply chains?
Researchers of great repute I call upon you all to address the issues as much as you can. Thanks a lot.

Hello,
Most hand sanitizers contain 60-80% alcohol. Alcohol destroys organisms including bacteria, fungi, protists, and enveloped viruses by breaking down the plasma membrane. In recent years, microbial communities on the skin, in the airways, and in the gut have been shown to play an important role in health. Does daily use of hand sanitizer negatively impact the diversity and strength of the hand microbiome? If so, what are the implications of this to overall health? Do skin microbes play beneficial roles such as helping to prevent transmission of other pathogens?
Thank you.
Wishing all of you and your families a healthy, peacefull, prosperous as well as success- and fruitful, happy and safe new year 2021 to come.

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.

In the context of this question, I'm not interested in debating the legitimacy, efficacy, or motivation for protesting in the present climate. Assume the protester intends to participate in some public group protest (that is, put aside protesting from home, e.g. boycotting online shopping, writing to policy makers, etc. for this question). I'm interested in best practices the protester can follow to keep themselves and others as safe as they can given these conditions. Some obvious examples: wear a mask, practice social distancing as much as possible, don't attend if you're exhibiting symptoms, etc. Perhaps less obvious examples: Bring extra masks, distribute sanitizer, etc.
Conventional academic journals are not designed for 'process improvement' studies that rely on time-series statistics.

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.
Thanks,
Sajad

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.

- Any vehicle may transmit an event-triggered BSM with high priority that must be routed through the vehicular network with very low delay
Some performance metrics to consider for both types of BSM (low and high priority):
- Packet Delivery Ratio
- Delay
I am working in a research project that tackles the construction workers safety and productivity and I need some information related to the typical crew size of construction workers in different construction activities. The main construction activities are: formwork, steel work, and concrete work.
