The notion of shielding of electrons in the same-shell provides a different sort of justification for the F. The fluorine ion F- has a net negative charge yet the electrons are some how clinging to it. There are two electrons in the first shell and seven in the second shell. Negatively charged ions are created when an atom acquires enough electrons to complete a shell. This is due to the shielding of some of the positive charge of the nucleus by electrons in the same-shell. Thus the energy required to remove an electron from a shell should decrease with the number of electrons in that shell. ![]() Where p is the number of protons in the nucleus. Thus if the number of electrons in a shell is denoted as ε 1Īnd there are ε 0 electrons located interior to the shell then the effective charge Z acting on one electron in the shell is Would have located at the center of the sphere. That effect is equal to what half the charge Located on particles located at the middle of that distributed charge. What is left out is the effect of a charge distributed on a spherical shell on a charge On the other hand, the effect on aĬharge within the sphere is zero. When a charge is distributed uniformaly on a spherical shell it has the effect on another charge outside of the sphereĮqual to what that same charge would have concentrated at the center of the sphere. First it is necessary to consider some aspects of The correct explanation of negative ions is entirely different from the matter of completing a shell of eight. ![]() Somehow the supposed energy advantage of a filled shell overcame theĮnergy disadvantage of bringing in a repulsive particle. My recollection is that these multiply negative ions were justified by the power involved inĬompleting a shell of eight. An entity with a net negative charge would be thought to repel an electron. There is an electron, with a negative charge, clinging to an entity O - which has a net negativeĬharge. O 2- without realizing what surprising, even puzzling, entities they are. In chemistry courses students blithely accept the notion of negative ions such as Cl - and The Puzzle and Explanation of Negative Ions

![]() It takes a look at your address book to find out what the good and acceptable messages look like so that it doesn’t end up confusing the messages you want for spam. Once you install and setup SpamSieve, it learns what your spam looks like, and manages to block most of them. It’s quite easy to use from within your Mail app, and you can even customize it - define rules for it to interact with the messages that arrive in your inbox. SpamSieve lets you reclaim your inbox by bringing the much-powerful Bayesian spam filtering technique to filter out spam in your Inbox app. They are harder to detect, and there’s always more of it - it takes more than just the default filters to get rid of that spam, and to save valuable time which you would otherwise spend sorting your inbox.Īnd this is where a good, trusted, time-tested and reliable spam filter for Mac like SpamSieve comes in. However, in recent times, spam has gotten more powerful. You can add rules and exceptions to where these spam messages go after filtering as well. Once you are there, make sure that you have checked the box labelled ‘Enable junk mail filtering’. You can access it in the Junk Mail setting under Preferences. The built-in spam filtering in Mail is enabled by default. It’s evident that nobody likes spam, and if you use the Mail application on your Mac, then you have a handful of options to filter out spam. SpamSieve, by far and large, is the best spam filter for the Mac.īut before we dive into our SpamSieve review, its features along with its user experience, let’s look at the built-in spam filtering option on Macs. With so much spam around, you must get access to the best E-mail spam filter. With spam in your inbox, you might be vulnerable to some severe phishing, fake invoices, and other misleading tactics that could cost you money. ![]() Spam doesn’t have a good reputation at all. ![]() Email spams also cost businesses $20.5 billion every year by hampering productivity. Besides, the sheer number of spam emails sent out every day is astounding - about 14.5 billion. Statistics around spam reveal that it makes for 45 percent of all sent emails, in which 36 percent of all spam is some form or advertising. While it might be easy to turn a blind eye to spam, it’s true that spam is a bigger problem than many think. Spams are horrible! They are unsolicited messages sent in bulk, and they infiltrate our inbox with unwanted information and promotional offers, and to our anxiety as well as the count of our unread emails to make our inbox look like a junk house. Additionally, genetics accounts for a big part of our VO2max. VO2max is highly correlated with body weight, height, age and gender. We can see the data with respect to all other participants of the same sex, on my dataset: For this participant (highlighted in the following figure), the HR while walking went around 115 bpm, while running as slow as 9 km/h hit more 170 bpm, pointing out the poor fitness level. As I mentioned before we can use the HR at predefined intensities as a proxy to fitness level, since higher HR typically indicates lower fitness level. In a dataset I collected during my PhD I had a participant who was very unfit, but also very light. Let's illustrate this issue with an example. Not-normalizing, while correct in principle, hinders interpretability since tables for different weight ranges don't exist. VO2max/kg), however they don't take into account the type of test performed to obtain VO2max, often over-correcting results. VO2max categories are based on normalized units (i.e. Especially when biking, the activity is non-weight bearing, which means the impact of body weight on oxygen uptake is very different compared to weight bearing activities such as running. Again, literature on different normalizations (and allometric coefficients) for activity-specific body weight normalization is inconsistent. VO2max is reported most of the times normalized by body weight, however t he relation between body weight and oxygen uptake is activity dependent. One of the major issues with VO2max is the total lack of agreement on body weight normalizations. How can we measure fitness if the gold standard is affected by such variability? However, such tests are the most commonly performed in research, since they are considered more practical and easier for participants that are not used to do sports (e.g. One of the reasons is that biking tests are often limited by muscle fatigue. And differences can be big, with running VO2max typically being higher. If you do a bike test and a treadmill test, you’ll get two different results. While VO2max is the gold standard, and by definition is the only way to determine fitness level, the exercise protocol performed highly influences results. However, some limitations still apply: the test needs to be re-performed every time that fitness needs to be assessed, still a pre-defined protocol is required. determining the HR during specific activities, was a good step forward in terms of practical applicability, compared to maximal tests. Basically, these tests rely on the inverse relation between fitness and HR, with higher HR typically associated to lower fitness level and viceversa. ![]() Submaxmial tests have been developed already more than 60 years ago to estimate VO2max during specific protocols while monitoring HR at predefined workloads. There are a series of practical limitations to VO2max testing, for example the need for specialized personnel, expensive medical equipment, high motivational demands of the subject, health risks for subjects in non-optimal health conditions (which limits applicability), and so on. VO2max is regarded as the most precise method for determining fitness. I’d love to engage in a deeper conversation on the complexities of determining fitness level, so if you are interested as a user, coach, or expert in the field, feel free to drop me a line.Ĭurrent practice for fitness assessment is direct measurement of oxygen volume during maximal exercise, i.e. I was mainly motivated by the lack of services (methods, apps, or whatever) able to track my fitness level as I keep training and try to improve my personal bests. I will also show some anecdotal evidence of the benefit of using the Fitness Index, based on my data. This post goes into the details of the limitations of current methods used to define fitness and how the Fitness Index overcomes some of these limitations. The indicator is called Fitness Index, and the app I developed around this concept is StayFit. I spent the last few weeks defining a new indicator of cardiovascular endurance and fitness, based on simple parameters that can be acquired with minimal effort using a mobile phone. Additionally, some of the research backing up the assumptions in this post have been recently published in Artificial Intelligence in Medicine, you can find out more here. ![]() ![]() However, I am currently including the Fitness Index as an additional Insight in HRV4Training, please check out HRV4Training if you are interested in physiological data, training, recovery and fitness.

( g = 10 m/s² ) Calculate the weight of a mass 2.6gram.įormula: weight = mass * acceleration due to gravity The formula is : weight = mass * acceleration due to gravityġ. This formula is used in calculations, to either calculate the weight of a given mass of object or to calculate the mass of a given weight. The relationship between mass and weight is the formula that connect mass and weight. The more the mass of an object, the more the inertia of that object will be, the more the resistance and the larger the force required to change the state of rest of the object or uniform motion. ![]() The mass of an object determines the amount of inertia / resistance that the object will offer to a force that act on it and try to change its state. Mass of an object is a measure of the inertia of the object. Mass of an object is the quantity of matter in the object. Or It can be defined as the force that is acting on the object due to the earth gravitational pull. Weight of an object is the gravitational pull on the object. Inertial mass is a property of a matter which represent a resistance that the resistance f the object to any type of force. The more the quantity of matter that is contained in an object, the larger the mass of the object. Mass is the quantity of matter that is contained in an object. Inertia is inherent in every object and is a property of very matter. Every object is unwilling to do other wise apart from what its is doing at the moment. Inertia is the unwillingness of an object in motion to stop moving or an object at rest to start moving. Newton’s first law of motion states that an object will continue in its state of rest or motion in a straight line unless it is acted upon by an external force. He stated three laws of motion which we shall look into in the treatment. ![]() This was discovered by Sir Isaac Newton ( 1642 – 1727 ). Therefore, forces are related to motions of objects. Motion of objects are caused by unbalanced forces that act on the objects. ![]() Amazon lockers are also available for use if you don’t want a package sitting on your doorstep.

I read up quickly on DKIM and it sounds like its a way to authenticate that emails did in fact come from my domain, so it sounds like its something I'd like leverage. Adding this new SES identity, it asked me to enter my domain and gave me the option to generate DKIM configurations for that domain. It is possible to verify individual email addresses or complete domains. ![]() I'm not sure if I need to do this or not (given my needs) or whether my myapp-dev user is ready to use the SES APIs as-is. While you are in the sandbox, all destination email addresses must be verified as well. Not knowing any better, I then went to the SES dashboard and clicked Manage Identities and started creating a new " SES Identity". Finally, in order for emails to work with our domain, we need an MX record that tells other mail servers where to send their ourdomain emails. until SES is able to witness the new DNS record we just created. I've already created a myapp-dev user that has AmazonSESFullAccess permissions. Instead, this is just going to wait until SES aknowledges the verification of the domain identity, i.e. Use a verified email address, or an address from a verified domain, as the FROM email address that you assign to your user pool. This is because some SES emails will be alerts/notifications that end users should not respond to, and other emails will be emails that they may very well want/need to reply to. Before you can use your Amazon SES configuration, you must verify one or more email addresses, or a domain, with Amazon SES. When you run the following code example, Amazon SES provides you with a verification token. When you verify a domain, you allow Amazon SES to send email from any address on that domain. By verifying a domain, you demonstrate that you’re the owner of that domain. Furthermore I need these SES-generated emails to be sent from either which is not a valid email address, as well as which is a valid email address. Amazon SES can send email only from verified email addresses or domains.
