Hard-surface cleaning in household application is represented by two classes of alkaline products: ( 1 ) the formulations made expressly for machine dishwashers, and ( 2 ) the general-purpose cleaners used for walls and woodwork.

Chemically, astatine behaves more or less as a halogen, being expected to form ionic astatides with alkali or alkaline earth metals ; it is known to form covalent compounds with nonmetals, including other halogens.

It has a milky taste and is alkaline.

In chemistry, an alkali (; from Arabic: al-qaly القلي, القالي ) is a basic, ionic salt of an alkali metal or alkaline earth metal element.

The adjective alkaline is commonly used in English as a synonym for base, especially for soluble bases.

The word " alkali " is derived from Arabic al qalīy ( or alkali ), meaning the calcined ashes ( see calcination ), referring to the original source of alkaline substances.

Soil with a pH value higher than 7. 3 is normally referred to as alkaline.

As a free element it is a steel-gray, strong, lightweight and brittle alkaline earth metal.

It is the fifth element in Group 2, a soft silvery metallic alkaline earth metal.

One effective strategy is to soak beans in alkaline ( baking soda ) water overnight before rinsing thoroughly.

A pH greater than 4. 5 is considered alkaline and is suggestive of bacterial vaginosis.

Calcium is a soft gray alkaline earth metal, and is the fifth-most-abundant element by mass in the Earth's crust.

Calcium, with a density of 1. 55 g / cm < sup > 3 </ sup >, is the lightest of the alkaline earth metals ; magnesium ( specific gravity 1. 74 ) and beryllium ( 1. 84 ) are more dense, although lighter in atomic mass.

Bags of cement routinely have health and safety warnings printed on them because not only is cement highly alkaline, but the setting process is exothermic.

Direct or substantive dyeing is normally carried out in a neutral or slightly alkaline dyebath, at or near boiling point, with the addition of either sodium chloride ( NaCl ) or sodium sulfate ( Na < sub > 2 </ sub > SO < sub > 4 </ sub >) or sodium carbonate ( Na < sub > 2 </ sub > CO < sub > 3 </ sub >).

In anaerobic, and particularly geothermal conditions, the divalent form is sufficiently stable that it tends to be incorporated into minerals of calcium and the other alkaline earths.

The FDA study concluded: "... steps such as heat, alkaline treatment, and filtration could be effective in reducing the level of contaminating TSE agents ; however, scientific evidence is insufficient at this time to demonstrate that these treatments would effectively remove the BSE infectious agent if present in the source material.

He is probably best remembered today for his discoveries of several alkali and alkaline earth metals, as well as contributions to the discoveries of the elemental nature of chlorine and iodine.

This is followed by reduction with alkali or alkaline earth metals in vacuum or argon atmosphere:

At pH 4. 8, the interior of the lysosomes is acidic compared to the slightly alkaline cytosol ( pH 7. 2 ).

The cell is additionally protected from any lysosomal acid hydrolases that drain into the cytosol, as these enzymes are pH-sensitive and do not function well or at all in the alkaline environment of the cytosol. This ensures that cytosolic molecules and organelles are not lysed in case there is leakage of the hydrolytic enzymes from the lysosome.

Lucretius has remarked: `` The reason why all Mortals are so gripped by fear is that they see all sorts of things happening in the earth and sky with no discernable cause, and these they attribute to the will of God ''.

He will not curb his instinctual desires but release the energy within him that makes him feel truly and fully alive, even if it is only for this brief moment before the apocalypse of annihilation explodes on earth.

He is a widower, his three children are dead, he has no one left on earth ; ;

They all have this in common: the earth is situated near the center of the deferent.

The distances of these points of light is a problem he cannot master, beyond crude conjectures as to the orderings of the planetary orbits viewed outward from earth.

Fourth, in the meantime, it is necessary to remember that we have only begun to probe the environment immediately surrounding the earth.

I bethought me of the Lord's Prayer, and these words came to mind: `` Thy kingdom come, Thy will be done, on earth as it is in heaven ''.

From that time to this my religious concern is that I might give effective help to the bringing in of God's kingdom on earth.

As to our action, let us align ourselves with the purpose expressed by Jesus in the Lord's Prayer: `` Thy kingdom come, Thy will be done, on earth as it is in heaven ''.

The space between them is filled with pit-run gravel or earth.

It's not a science as involved as determining what makes the earth rotate on its axis or building a rocket or putting a satellite into orbit but it is, nevertheless, a science.

My unscientific friend does not believe that human stature is measurable in terms of speed, momentum, weightlessness, or distance from earth, but is a matter of the development of the human mind.

For the case of Jupiter, the radio emission spectrum is definitely not like the spectrum of a black-body radiator, and it seems very likely that the radiation reaching the earth is a combination of thermal radiation from the atmosphere and non-thermal components.

No attempts to measure the radio emission of the remaining planets have been reported, and, because of their distances, small diameters, or low temperatures, the thermal radiation at radio wave lengths reaching the earth from these sources is expected to be of very low intensity.

The maximum angular diameter of any planetary disk as observed from the earth is about 1 minute of arc.

The inhibition of the enzyme by very low concentrations of lanthanum ion is probably the strongest known biological effect of rare earth salts.

The input axis of the X gyro, when pointing in the east-west direction, is always perpendicular to the spin axis of earth.

In Fig. 7-4, the input axis of the three-axis platform is shown at some point on the earth.

The earth is spinning at an angular velocity **zq equal to one revolution per 24 hr..

Since the earth is rotating and the unleveled gyro-stabilized platform is fixed with respect to a reference in space, an observer on the earth will see the platform rotating ( with respect to the earth ).
