Nuclides with the same atomic mass number, but different atomic and neutron numbers, are called isobars. [8] The mass of a nucleus is always slightly less than the sum of its proton and neutron masses: the difference in mass represents the mass equivalent to nuclear binding energy, the energy which would need to be added to take the nucleus apart.
Keratosis obturans is a relatively uncommon ear disease, where a dense plug of keratin, formed by abnormal accumulation of desquamated skin in sheet like layers , forms in the bony (deeper) part of the external auditory canal. [1]
Zygoma reduction, also known as cheekbone reduction surgery, is a surgery used to reduce the facial width by excising part of the zygomatic bone and arch. Wide cheekbones are a characteristic facial trait of Asians, whose skull shapes tend to be more brachycephalic (broad, short skull) in comparison with Caucasian counterparts, whose skull shapes tend to be more dolichocephalic (narrow and ...
The tumor is usually solitary and presents as a slow growing, painless, firm single nodular mass. Isolated nodules are generally outgrowths of the main nodule rather than a multinodular presentation. It is usually mobile unless found in the palate and can cause atrophy of the mandibular ramus when located in the parotid gland. When found in the ...
In Catholic teaching, the holy sacrifice of the Mass is the fulfillment of all the sacrifices of the Old Covenant. In the New Covenant, the one sacrifice on the altar of Calvary is revisited during every Catholic Mass. Jesus Christ merited all graces and blessings for us by His death on the Cross.
An overview of ranges of mass. To help compare different orders of magnitude, the following lists describe various mass levels between 10 −67 kg and 10 52 kg. The least massive thing listed here is a graviton, and the most massive thing is the observable universe.
For a Higgs mass of 125 GeV/c 2 the SM predicts that the most common decay is into a bottom–antibottom quark pair, which happens 57.7% of the time. [2] The second most common fermion decay at that mass is a tau–antitau pair, which happens only about 6.3% of the time. [2]
A branchial cleft cyst or simply branchial cyst is a cyst as a swelling in the upper part of neck anterior to sternocleidomastoid.It can, but does not necessarily, have an opening to the skin surface, called a fistula.
