By the phrase ‘open-handed’ the poet implies to the map of the world that is drawn and reshaped at will by dictators like Hitler who want to gain supreme power over the world.

• Mr. Lamb had an optimistic attitude towards life.  
• Though he was lame and had one leg made up of steel, he always used to be inspiring and believed in living life to the fullest.  
• I really like Mr. Lamb’s attitude towards life.
• An instance of this could be seen when he inspired Derry to look at the world in a hopeful manner, he also told him that his face does not mean anything if he has a good heart.

The Central government in India made a law for the Right to work in 200 districts of India is called National Rural Development Guarantee Act 2005 (NREGA, 2005). It is also known as Mahatma Gandhi National Rural Development Guarantee Act 2005 is an Indian labour law and social security measures that guarantees work. People who are able to and are in need of work are guaranteed 100 days of employment in a year by the government under this Act and the government give unemployment allowances to the people, if they fails to provide employment.

Charley was greatly amazed when he reached the hundred year old third level and was planning to buy two rail tickets to Galesburg where he had spent his childhood. But when he took out his money to pay the fare, the clerk found out that his notes were fake and thought that Charley was attempting to fool him.

Working of democracy in Pakistan :
(i) After Pakistan framed its first constitution, General Ayub Khan took over the administration of the country and soon got himself elected. He had to quit the office when there were agitations and dissatisfaction in his rule. This gave a way to the military to takeover the government of the country.

(ii) After 1971, an elected government was formed under the leadership of Zulfikar Ali Bhutto, which was removed by General Zia-ul-Haq in 1977.

(iii) Again in 1982, in Pakistan, by a pro-democracy protest, democratic government was established in 1988, under the leadership of Benazir Bhutto and Nawaz Sharif. Later on, history repeated and General Pervez Musharraf again took the command in 1999 and got elected in 2005.

(iv) It is, therefore, said that military rule and ‘ democracy are two sides of the coin in Pakistan.
Though Pakistan’s politics centered around the competition between People’s party and Muslim League, Several factors have contributed to Pakistan’s failure in building a stable democracy.

Let

X,  be the initial length, and r

Y be the cross-sectional area

R be the resistance of wire.

Let X', Y' and R' be the new length, cross- sectional area and resistance of wire after the length of wire is increased.

Length is increased by 0.1%, therefore,

L' = L+(0.1/100)L

L' = 1.001 L

Since the volume of wire remains same, thus,

V' = V

A'*L' = A*L

A' * 1.001 L = A*L

A' = A/1.001

New Resistance,

R' = ρL'/A'

= ρ*1.001 L/(A/1.001)

= (1.001)²(ρL/A)

R' = 1.002*R

% change in resistance = (Final resistance - Initial resistance)/Initial resistance * 100%

= (R' - R)/R*100%

= (1.002R - R)/R*100%

= 0.002 * 100%

= 0.2%

Thus, resistance of wire is increased by 0.2%.

Q u e s t i o n : An element crystallizes in a fcc lattice with cell edge of 400 pm.  The density of the element is 7 g cm^-3. How many atoms are Present in 280 g of the element ?

A n s w e r :

Volume of the unit cell a³ = (400 pm)³ 

Step I. Calculation of mass of an atom of the elements
Let the mass of an atom of the element = m gram
Mass of the unit cell = 4×m=(4m) 
Edge length (a)= 400 pm = 400pm ×10⁻¹⁰ 
Volume of the unit cell =(400×10⁻¹⁰cm)³=64×10⁻²⁴cm³
Density of unit cell = 7 g cm⁻³ 
Density of unit cell =Mass of unit cellvolume of unit cell=Mass of unit cellvolume of unit cell
(7 g cm⁻³)=(4m)g/ (64×10⁻²⁴cm³) 
m=(7gcm−3)×(64×10−24cm3)/ 4=112×10⁻²⁴g 
Step II. Calculation of the number of atoms in 280 g of the element.
No. of atoms=Mass of the elementMass of one atom of the elementNo. of atoms=Mass of the elementMass of one atom of the element
=(280g)/(112×10⁻²⁴g)=2.5×10²⁴atoms

NOTICE

Students kindly note there is an international book fair held at Pragati Medan from 7th to 14th January 2021. Time : 7:30 a.m in the morning to 2:30 a.m till night.

Hereby , the students interested are requested to come at laest once and just check as it would be a good oppurtunity for all to see and suggedt some books for library purpose.

Due to smaller atomic size the density of lone pair electrons on N in NH3 is larger than that of P in PH3. So, NH3 is a stronger Lewis base than that of PH3.

Physiology is the study of the characteristics and mechanisms of the human body.

Cells are the basic unit of life and approximately 100 trillion cells make up the typical human, each specially adapted to perform one or a few particular functions. Nearly 25 trillion red blood cells function by transporting oxygen from the lungs to all tissues in the body. All cells have some basic commonalities. Oxygen reacts with carbohydrates, fat, and protein to release energy, nutrient consumption, and energy production mechanisms. Almost all cells have the ability to reproduce further similar cells.

Psychological models maintain that psychological and interpersonal factors have a significant role to play in abnormal behaviour. These factors include:

• Maternal deprivation (separation from the mother, or lack of warmth and stimulation during early year of life).

• Faulty parent-child relationships (rejection, overprotection, over-permissiveness, faulty discipline, etc.

• Maladaptive family structures (inadequate or disturbed family) arid severe stress.

The psychological models include the psychodynamic, behavioural, cognitive, and humanistic-existential models.

(a) The Psychodynamic Model: This model is the oldest and most famous of the modem psychological-models.

Abnormal behaviour is viewed as the result of intrapsychic conflicts.

• This model was first formulated by Freud.

• Abnormal behaviour is a symbolic expression of unconscious mental conflicts that can be generally traced to early childhood or infancy.

Brahmi and Kharoshthi scripts

The inscriptions of Asoka were first deciphered by James Princep in 1837. They are written in Pali language and in some places Prakrit was used. The Brahmi script was employed for writing.In the northwestern India Asokan inscriptions were found in Karoshti script.

सिंधु-सभ्यता की खोज की शुरुआत में यह माना जा रहा था कि इस घाटी के लोग अन्न नहीं उपजाते थे। वे अनाज संबंधी जरूरतें आयात से पूरा करते थे, परंतु नयी खोजों से पता चला है कि यहाँ उन्नत खेती होती थी।
अब कुछ विद्वान इसे मूलत: खेतिहर व पशुपालक सभ्यता मानते हैं। खेती में ताँबे व पत्थर के उपकरण प्रयोग में लाए जाते थे। यहाँ रबी की फसल में गेहूँ, कपास, जौ, सरसों व चने की खेती होती थी। इनके सबूत भी मिले हैं। कुछ दिनों का विवार है कि यह ज्वार, बाजा और साग को उज भी हती थी। लोग खज्र खल्वे और अंगूर उगाते थे।

Payment to a retiring partner can be made in the following ways
(i) Lump Sum Payment : A lump sum payment can be made to the retiring partner in full settlement. In that case, the following Journal entry will be passed

(ii) Opening the Loan Account: Sometimes the amount due to the retiring partner is paid in instalments then the balancing figure of his/her capital account is transferred to his/her loan account, in this case, the retiring partner receives equal instalments along with the interest on the amount outstanding. In that case the following journal entries will be passed for transferring the amount paid to him/her in retiring partner’s loan account.

(iii)Some Payment in Cash and Some in Instalment: Sometimes the amount due to the retiring partner is paid partly in cash and partly in equal instalments in that case a certain amount is paid in cash to the retiring partner and the rest amount due to him/her is transferred to his/her loan account. The following necessary journal entry is to be passed. 

in case of retirement,the partners can retire only at the end of an accounting year whereas death of a partner may occur at anytime during the year.

Quartiles divide the entire set into four equal parts. So, there are three quartiles, first, second and third represented by Q₁, Q₂ and Q₃, respectively. Q₂ is nothing but the median, since it indicates the position of the item in the list and thus, is a positional average. To find quartiles of a group of data, we have to arrange the data in ascending order.
