Patient discussion about declination

Q. what can be the reasons my hearing capability decline? i am 30 years old ... and i'm in great shape , don't have chronic health issues , never had . but recently i found my self "missing" parts while my friends are speaking to me , and it is not just that , i feel like my hearing capability decline rapidly for the last few months , what can it be ? and what should i do ?

A. There are many possible reasons for hearing loss. It can be due to a simple ear-wax plug, that can be easy taken out by a Ear-Nose-Throat specialist. It can also be due to a chronic middle ear infection, or gradual hearing damage due to loud noise. Either way you should see a doctor that can refer you to further evaluation tests.

Procedural declinations were the smallest cited category, accounting for only three percent of reasons endorsed by AUSAs.
This finding is in keeping with the hypothesis that the reason for the overall reduction in declinations during this period is a result of the fact that more resources were available to U.
Although issues related to adequate resources are ever-present, resource problems were themselves identified as being over-represented in declinations only in Los Angeles, Salt Lake City, and Burlington.
2 The orientation of the passage tomb points at a saddle between the conspicuous hills of Mid Hill and Ward Hill, but the declination (-10 [degrees] [multiplied by] 6) has no obvious astronomical interpretation -- and certainly none in terms of Thom's 16-month calendar, for which the closest epoch declination is around -8 [degrees] [multiplied by] 5 (Ruggles 1999: 55).
For a few days around midwinter, the disc of the setting sun would have passed across this cleft (whose lowest point has a declination -25 [degrees] [multiplied by] 0).
A shallow dip in the horizon at this point, whose declination according to MacKie is -0 [degrees] [multiplied by] 1, corresponds roughly to equinoctial sunrise, although the upper limb of the equinoctial sun would actually appear approximately 1 [degrees] (two solar diameters) to the left.
It was also more convenient, as mentioned earlier, to use star pairs as equal altitudes initially with either equal or unequal declinations as in abdal measurements.
In order to compare abdal and "fettering" methods, table 3 shows one star pair of nearly equal declinations and another pair whose declinations differ considerably, and one star of each pair fettered--both pairs calculated using the modern nautical and navigational triangle tables.
Equation 6 can be used as a tool for evaluation of the potential reduction of heating water leakage of the existing leakage rate in the piping system at different declinations of pump proportional pressure control curves.
The load profile of a pumping system for a certain part of a district heating system should be taken into account in order to analyze the consumption of electrical energy if the certain declination of pump proportional pressure control curve is used (Figure 3).
In other locales, a compass needle slews either to the left or the right of true north by a certain angle, a process commonly known as declination.
What many scientists didn't appreciate until the 1600s, after they had compiled a few decades' worth of precise measurements at astronomical observatories, was that declination varied through time.
