In the periodic table, elements are classified into metals, nonmetals, and metalloids. Metals are ductile, malleable, shiny, are good conductors for heat and electricity. All metals are solids at room temperature and pressure except, Mercury. Nonmetals exist as solids, liquids, or gases. A liquid non-metal at room temperature and pressure is Bromine.

2. The elements in the d-block in the periodic table have several characteristics in common.

(i) Give the electron configuration of N²⁺

1S2 2S2 2P3- 2= 1S2 2S2 2P1

(ii) Explain what is meant by a ligand and describe the type of bond formed between a ligand and a d-block element.

It is an atom or molecule with a lone pair of electrons that combine with a metal through coordinate covalent bonding. In transition... Continue reading "Chemistry Basics: Metals, Nonmetals, and Transition Elements" »

The Model of Valuation of Financial Assets by the Arbitrage Pricing Theory

Stephen Ross developed this theory in 1976. It is an equilibrium model for asset valuation. Its central idea is the expected return on an asset must be a linear function of its systematic risk. The APT considers that the only risk that the market is willing to remunerate is the systematic one, since the rest of the risk can be eliminated via diversification. According to this model, the systematic risk is the fundamental explanatory factor of the performance of the profitability of financial assets, although that is not measured only by the beta coefficient of the profitability of an individual asset with respect to the profitability of the market portfolio, but by a...

Linguistic Concepts

2. (1.5p) Define the following concepts as they have been used in this course, giving an example of each:

Meronymy

Meronymy is the semantic relation between a lexical item denoting a part and that denoting the corresponding whole. Meronyms are mentally triggered, since our minds have scripts, e.g., knowledge about event sequences due to knowledge of the world. We have scripts for events that commonly occur in our lives, such as going to a doctor's office, a restaurant, a library, or the supermarket.

Converses

Converses are pairs of opposite terms characterized by the following feature: when one member of the pair is substituted for the other, the new sentence can be made logically equivalent to the original one by interchanging... Continue reading "Linguistic Concepts: Definitions and Examples" »

My Future Starts Now

What do you think your future self will thank you for?

Good morning, I’m here today to tell you about how your choices affect your future and have a big impact on the rest of your life.

Our future is decided by the everyday choices we make or choose not to make. If you don’t want to decide yourself, you let someone else decide for you or you just don’t make the decision, [ZW3] but you don’t know what would have happened if you had made the decision yourself or if you had made a different decision. In books, movies, and TV shows, people say that you can’t change the future, but just by making different choices, your future might look way different.

The Importance of Choices

Minimum Level or Safety Stock

The minimum level is the minimum quantity of the material which must be maintained in hand at all times. The quantity is fixed so that the production is not held up due to shortage of the materials. In fixing this level, the following factors should be considered:

• Lead time i.e. time lag between indenting and receiving of the material. It is the time required to replenish the supply.
• Rate of consumption of the material during the lead time.
• Nature of the material. Minimum level is not required in case of a special material which is required against customer’s specific order.

Maximum Stock Level

It is the maximum of stock which should be held in stock at any time during the year. The quantity is fixed so as to avoid... Continue reading "Inventory Management Techniques and Time-Keeping Methods" »

Hate Me

Ellie Goulding & Juice WRLD

Lyrics

Hate me, hate me, still tryna replace me
Chase me, chase me, tell me how you hate me
Erase me, 'rase me, wish you never dated me
Lies, tell me lies, baby, tell me how you hate me

I bet you don't kiss her with your eyes closed
I bet you're still walking on a tightrope
Miss me so much, you've been goin' psycho
You ain't gotta say it, baby, I know (I know, I know, I know)

It's a thin line between all this love and hate
And if you switch sides, you're gon' have to claim your place
So baby, this time you're gon' have to seal your fate
Yeah baby, this time you're gon' have to seal your fate

And tell me how you hate me, hate me, still tryna replace me
Chase me, chase me, tell me how you hate me
Erase me, 'rase me, wish... Continue reading "Hate Me - Ellie Goulding & Juice WRLD Lyrics" »
