In the following orbital the lone pair on each N atom is present:
N1: sp3,
N2: p,
N3: p,
N4: sp2,
N5: sp2
Sitagliptin is an anti-diabetic drug used to treat type 2 diabetes and is marketed under the brand names Januvia and others. One carbon atom has no pi bonds, while the first nitrogen atom is linked to two hydrogen atoms. It thus possesses sp3 hybridization.
The second nitrogen atom possesses a single pair of electrons and is bound to three other atoms. It is hence sp2 hybridized. The nitrogen atoms in positions 3, 4, and 5 have sp2 hybridization.
The lone pair of nitrogen in the first nitrogen atom is in the sp3 orbital. The second and third nitrogen atoms' only pair of electrons are in p-orbitals. The fourth and fifth nitrogen atoms' lone pair of electrons are in sp2 orbitals.

PAD is physical aid in dying. It is also known as assisted /uicide.
Oncology is the study of cancer. And a cancer specialist is referred to as an oncologist. Many times patients with severe medical conditions want to end their life. This is done with help of a physician. This is referred to as physician aid in /ying (PAD). Cancer has gained a lot of attention from PAD. The oncologist should before taking any step should consider that the patient has access to palliative options and it should be maintained that they have adequate counseling. PDA is becoming legal in the United States of America.
Whether physicians stand in support of PDA or they consider it an unethical practice, they must have a framework within which to accept and process a patient’s request for physician aid in /ying.

Answer:
In general Asian music, but most particularly Chinese, has called the attention of westerners because of the sensed differences with the music that we are accostumed to listen to in the west. This is why, when we go into a restaurant that is Asian, and we hear the tunes being played, we become aware of how different they sound from what we are accustomed to.
There are several reasons for why this happens, but the most important of all is the difference in the scale system that Chinese music composers use, versus ours. While in the west we use a 7-note scale system, most Asian music, and most particularly Chinese music, use what is known as the pentatonic, or 5-note scale.
Also, Chinese music is usually played with solo instruments, or very small ensembles, not how it is done in the west, and the emphasis tends to be on certain types of wind instruments such as zheng, and also on cymbals and gongs, which give this type of music a very peculiar characteristic.
These are only a few of the reasons why Chinese music may sound so different to what western people are used to.
