Negative conception of liberty:

• It implies the absence of restraints and rights to do whatever one likes.
• This conception may make the powerful person more powerful to keep the weaker ones on their mercy.
• This conception of liberty faces the following drawbacks:

(a) Liberty is concerned with the area control, not with its source, hence, this is not necessary to have democracy to enjoy freedom.

(b) The state should control the liberty of an individual only up to the limit where he interferes in other’s such liberty. Positive conception of liberty:

• It refers to the society in which adequate facilities are available for each and every section of society to enjoy desirable rights.
• This believes that any individual or section should not hinder the progress of others.
• People can enjoy all freedoms which are permissible by laws.
• It ensures the growth of poor, weak and downtrodden people also.
• It interprets that liberty lies in the removal of hindrances.

Contra entry represents deposits or withdrawals of cash from bank or vice versa. The purpose of contra entry is to indicate the transactions that effect both cash and bank balances. This entry does not affect the financial positions of a business. A contra entry is recorded in both sides of a two column Cash Book and is denoted by ‘C’ in the ledger folio column.

The Fibonacci sequence, also known as Fibonacci numbers, is defined as the sequence of numbers in which each number in the sequence is equal to the sum of two numbers before it. The Fibonacci Sequence is given as:

Fibonacci Sequence = 0, 1, 1, 2, 3, 5, 8, 13, 21, ….

Here, the third term “1” is obtained by adding first and second term. (i.e., 0+1 = 1)

Similarly,

“2” is obtained by adding the second and third term (1+1 = 2)

“3” is obtained by adding the third and fourth term (1+2) and so on.

For example, the next term after 21 can be found by adding 13 and 21. Therefore, the next term in the sequence is 34.

The poem THE LABURNUM written by Ted Hughes

• The leaves of the  Laburnum tree had turned yellow .
• The seeds too had fallen down.
• The tree had become lifeless.
• The arrival of the Goldfinch bird brought a new life in it.
• The tree had become her shelter and younger ones.
• She had a dark colored face with stripes on it which was quite visible.
• However her body which was yellow in color made her barely visible as it would mix with the color of the leaves which too was yellow in color.

Temples overtime developed huge structures, built in shape of step pyramids. But early temple were much like house. They were small shrines made of unbaked bricks except that had outer walls going in and out at regular intervals unlike ordinary building. Early temples were like a house because:
(i) The temple symbolize the community as a whole and was the nucleus around which the city developed.
(ii) It was here that the processing of produce- grain grinding, spinning, weaving was done as in household.
(iii) The rulers of early Mesopotamia's cities were priests.They lived and administered from there. Since temples were used for residential purposes they looked like houses.
(iv) The complex was not only a place of rituals and worship but contained warehouses, workshops and living quarters of artisans.

sp Hybridization

sp hybridization is observed when one s and one p orbital in the same main shell of an atom mix to form two new equivalent orbitals. The new orbitals formed are called sp hybridized orbitals. It forms linear molecules with an angle of 180°

• This type of hybridization involves the mixing of one ‘s’ orbital and one ‘p’ orbital of equal energy to give a new hybrid orbital known as a sp hybridized orbital.
• sp hybridization is also called diagonal hybridization.
• Each sp hybridized orbital has an equal amount of s and p character, i.e., 50% s and p character.

sp³ Hybridization

When one ‘s’ orbital and 3 ‘p’ orbitals belonging to the same shell of an atom mix together to form four new equivalent orbital, the type of hybridization is called a tetrahedral hybridization or sp³. The new orbitals formed are called sp³ hybrid orbitals.

• These are directed towards the four corners of a regular tetrahedron and make an angle of 109°28’ with one another.
•  The angle between the sp3 hybrid orbitals is 109.28⁰
• Each sp³ hybrid orbital has 25% s character and 75% p character.
• Example of sp³ hybridization: ethane (C₂H₆), methane.

जो पदार्थ पतली और लगातार लड़ी के रूप में रहता है उसे तंतु कहते हैं।

तंतु के प्रकार

प्राकृतिक तंतु: जो तंतु पौधों या जंतुओं से मिलते हैं उन्हें प्राकृतिक तंतु कहते हैं। उदाहरण: रुई, जूट, रेशम और ऊन। प्राकृतिक तंतु दो प्रकार के होते हैं: पादप तंतु और जंतु तंतु। रुई और जूट पादप से मिलने वाले तंतु हैं। रेशम और ऊन जंतुओं से मिलने वाले तंतु हैं।

संश्लेषित तंतु: जिस तंतु का निर्माण मानव द्वारा होता है उसे संश्लेषित या संश्लिष्ट तंतु कहते हैं। उदाहरण: नायलॉन, एक्रिलिक, पॉलिएस्टर।

Density of solid decreases as be increase the temperature. Since mass remains the same but volume increases with increase in temperature that results in decrease in density.

I had a dream come true last weekend, quite literally. For the first time in about six months, I was able to browse in a bookstore (one in my neighborhood that's reopened with sanitary and social distancing protocols clearly posted) while wide-awake. In the past, leaving the store without buying anything had felt like a triumph of willpower, but this time it involved some guilt. Only one other person was in the store during my visit, a clerk, and it only seemed fair to her to purchase something. Next time, for sure.

To be clear, I am not exactly wanting for reading material, but the element of wish fulfillment is intense even so. Likewise with my spouse, who reports having theater dreams. She has attended at least one play a week, on the most conservative estimate, throughout her entire adult life -- or did until this spring. Performances by excellent companies are livestreamed now, and she has been able to take theater classes online. But there’s more to going to theater than seeing a play -- a ritual-like aspect that can’t be broadcast. Browsing indulges curiosity and involves a degree of chance. The hunger is not for content but for certain qualities of experience, in part communal, that are lost or on hold for the duration.

The possibility of turning crisis into opportunity comes up in one of the essays on working from home that appears in the latest issue of the Journal of Scholarly Publishing. “How many of you,” asks Erika Dyck, a history professor at the University of Saskatchewan, “have dreamed of pressing pause on the work treadmill? I am talking about a genuine freeze-frame, reset, and rethink, or a chance to read something that isn’t directly related to a task with a deadline.”

But think again: “Let’s not kid ourselves; working from home during a pandemic is not that.” Before the pandemic, Dyck had what seemed like a modus vivendi that balanced parental responsibilities and academic work, including her role as a co-editor of the Canadian Bulletin for Medical History. “Now,” she writes, “despite being relatively isolated or even hiding in a home office, I consistently feel tired and am unable to focus on anything, especially when it comes to writing … My mind has constantly wandered, whether drifting toward the contents of the fridge and the looming prospect of dinner, or more often enveloping me in a fog of wondering whether any of the work we do as academics really matters, or whether we will still have academic institutions in a post-COVID world.”

Dyck’s is the most confessional of the essays and, no doubt for that reason, the one that made the most impression on me. At some point her trouble writing it became integral to what she had to say -- in particular, to acknowledging the trouble with “feeling like we need to be productive while people are dying, losing jobs, hungry and scared.”

The other four contributors to “A Compilation of Short Takes on Working from Home” recount different levels of difficulty in adjusting to the disruption. Bryan Birchmeier, an intellectual property coordinator at Michigan Publishing and the University of Michigan Press, frames it as a less physically grueling version of the phase known as “tear-down” or “total control” that he went through as in boot camp: “It’s meant to break down any barriers recruits may have to adjusting to a military schedule and to military procedures … We have had to create or adjust to a new schedule and new procedures because so much about our daily routine is different …”

At the other extreme is the experience of Olivier Lebert, the manager for two Canadian journals for 15 years, who has telecommuted for 11 of them -- and from France for the past 10. It sounds like the pandemic has not called for that much change in routine, and he can sum up best practices very clearly: establish a schedule. Stick to it. Meet deadlines. Outside your set working hours, relax: “stop responding to professional calls or emails.”

An electrolyte is a substance that dissociates in water into charged particles called ions. Positively charged ions are called cations. Negatively charged ions are called anions. Simply, an electrolyte is a substance that can conduct an electric current when melted or dissolved in water.

Histamine is an organic compound, which is involved in local immune responses and also acts as a neurotransmitter. It is also involved in the inflammatory response and is a mediator of pruritus. Histamine is produced by basophils and is found in tissues that are connected nearby.
