These are hydraulic modelling (with GIS application) of flood inundation, analysis of satellite images to determine different physical elements at risk and using quantitative method (questionnaire survey) to gather information about flood damages to different types of physical risk elements in the study area. The principal sources of floods in Bangladesh are the river floods from the major river systems in the monsoon months. A broad strip of land extending beyond the active river floodplains is subjected to this type of flood. The northern and north-eastern trans-boundary hill streams are susceptible to flash floods from the adjacent hills in India in the pre-monsoon months of April and May. Flash floods cause extensive damages to crop and property, particularly in the haor (wetland) areas in the northeast region (Brammer 1999). They cause massive damage to dry-season boro (rice variety) rice crop just before or at the time of harvesting. Baniachong Upazila with an area of 482.25 km2 is located in the Agro-ecological Zone-20: Eastern Surma-Kushiyara Floodplain.

How Computer Get Internet Threats? Unauthorized access is a big risk for your computer. If your computer is not properly secured it is exposed to threats.

As soon as you click on "yes" some thing will be installed on your computer quickly. There are two types of Internet services that ISP (Internet Service Provider) provides. They are dialup and cable or DSL services. The dialup is a slow and low cost but less security threat. Cable or DSL is a fast Internet and more security threat if the computer is not protected properly. Anyone can easily transfer viruses or install any software for their own purposes.

In this article we will explore how to block emails on Gmail. When you get unwanted, unnecessary, and annoying emails in your Gmail inbox, you might want to block them. Blocking an email indicates that the sender of the email no longer sends an email to your inbox, and they will be unable to communicate with you through emails in the future. Also, you can report the senders when they violate Gmail's Program Policies. When do you need to block an email? If the sender asks you for sensitive information like - personal info, password, bank account details, transaction details, OTP, and job or career-related data, you should immediately block them. So, be aware of these spammers. You may get poorly written emails in your Gmail inbox. Most of the time, these emails include several miss-spelled words, grammatical errors, and unprofessional writing approaches. Undoubtedly, these emails come from scammers. Sometimes, you may receive an email that contains a link from an unknown sender frequently.

Complaint rate is the rate a subscriber marks an email as spam. A complaint rate is calculated by taking the total number of complaints and dividing it by the total number of recipients. Your goal should be to keep your complaint rate no higher than 0.1 percent. Conditional content, also known as Dynamic Content, allows you to display different text, visuals, or calls to action within an email to certain people. Content can change based on subscriber data and behaviors. Tags can be used to identify different groups of people and display alternate content within a single email message. Confirmed opt-in, also known as verified opt-in or sometimes double opt-in, means that a recipient (your subscriber) has verifiably confirmed permission for the address to be included on your specific mailing list. By confirming (clicking the link in this message) a subscriber has given you expressed permission to send messages to their address. Conversion rate is a desired action taken by the recipient of your email or website.

So in the FIDO2 model, each credential gets three new pieces of metadata: a username, a user display name, and a user ID. The username is a human-readable string that uniquely identifies an account on a website (it often has the form of an email address). The user display name can be a more friendly name and might not be unique (it often has the form of a legal name). The user ID is an opaque binary identifier for an account. The user ID is different from the other two pieces of metadata. Firstly, it is returned to the website when signing in, while the other metadata is purely client-side once it has been set. Also, the user ID is semantically important because a given security key will only store a single discoverable credential per website for a given user ID. Attempting to create a second discoverable credential for a website with a user ID that matches an existing one will cause the existing one to be overwritten.
