Lumba, латинский
Lumbaalinen hermo, финский
Lumbaalipunktio, финский
Lumbago, английский
Pain in the lower back (informal ) she has been suffering from lumbago for years. he has had an attack of lumbago.
Lumbago, латинский
Lumbales (i и ii); собирают кровь от мышц спины, английский
Lumbales (iii и iv); собирают кровь от мышц спины, английский
Lumbalis [e], латинский
Lumbar, английский
Поясничный: the lumbar region
Lumbar, испанский
Lumbar artery, английский
One of four arteries which supply blood to the back muscles and skin
Lumbar cistern, английский
A subarachnoid space in the spinal cord, where the dura mater ends, filled with cerebrospinal fluid
Lumbar enlargement, английский
The wider part of the spinal cord in the lower spine, where the nerves of the lower limbs are attached
Lumbar plexus, английский
The point where several nerves which supply the thighs and abdomen join together, lying in the upper psoas muscle
Lumbar puncture, английский
- Punción lumbar
- A surgical operation to remove a sample of cerebrospinal fluid by inserting a hollow needle into the lower part of the spinal canal. also called spinal puncture (note: the us term is usually spinal tap.)
Lumbar region, английский
The two parts of the abdomen on each side of the umbilical region
Lumbar support, английский
Many of our sofas come with additional inbuilt lumbar support. providing a supportive, curved shape to give extra shape to your body/back.
Lumbar vertebra, английский
Each of the five vertebrae between the thoracic vertebrae and the sacrum
Lumbar/cervical roll, английский
Almohada, almohadilla cervical, lumbar
Lumber, английский
- A north american synonym for timber.
- The product of the saw and planing mill for which manufacturing is limited to sawing, resawing, passing lengthwise through a standard planing machine, crosscutting to length, and matching
- Lumber having one or more of its faces planed smooth.
- Logs as they arrive at the mills. also, timber of any size, sawed or split for use. also, things stowed without order.
- Пиломатериал
- Старая мебель, громоздкие ненужные домашние вещи лишний жир (особ. у лошадей)

Bark residue, английский
Refers to the bark removed from a log and also to portions of wood and foreign matter such as sand, grit, or stones that may be imbedded in the bark (1).
Specific gravity, английский
- Ratio of the weight of a volume of material to the weight of an equal volume of water at a given temperature (7).
- The ratio of the density of wood to the density of water at 4 c. specific gravity of wood is usually based on green
- The density (mass per unit volume) of any material divided by that of water at a standard temperature.
- The ratio of the weight of a given volume of material to the weight of an equal volume of water.
- Плотность
- Удельный вес
- A measure of how tightly packed the atoms of a substance are. varies by the mineral or substance. example, gold has a high specific gravity, while quartz has a low specific gravity. see also "density."
- As applied to wood, the ratio of the ovendry
- This measurement of weight is expressed in grams per cubic centimeter. a lower specific gravity means a lighter weight lens.
- Same as relative density
- The comparative weights of equal bulks of different bodies, water being generally represented as unity.
- In liquids such as drill mud, or solids such as diamond, the weight of a given volume as compared with an equal volume of pure water at 4° c.
- The ratio of a material’s density to that of water [ material weight in air ? (weight in air - weight in water)]. used to differentiate different kinds of volcaniclastics and other materials. sw
- The ratio of the weight of the solution to the weight of an equal volume of water at a specified temperature. used as an indicator of battery state-of-charge.
- Ratio of the mass of a material to the mass of an equal volume of water at 4°c. the range for modern fibers is not too great and is dependent to some extent on the liquid used as an immersant in measurements, because of fiber swelling and of possible absorption of liquid into fiber voids. (also see density.)
- The ratio of the density of a substance to the density of water. the specific gravity of water is at standard condition temperature and pressure.
- Term used in connection with testing a battery`s electrolyte. a specific gravity test is used to determine the battery`s state of charge. sealed “maintenance free” batteries sometimes have an indicator on top that indicates the state of charge.
- The density of a substance divided by the density of water. water has a density of 1 gram/cm3. the closer a lubricant’s specific gravity is to 1, the greater its tendency to absorb moisture and have poor demulsibility.
- The ratio of the density of a substance to the density of water, often at a specified temperature.
- Unitless ratio of the density of a material divided by the density of water. water has a density of about 1 g·cm–3, or 1000 kg·m–3.
- Unitless ratio of the density of a material divided by the density of water. water has a density of about 1 g/cm3, or 1000 kg/m3, at 15.6 °c (60 °f).
