Ferrocement or ferro-cement [1] is a system of construction using reinforced mortar [2] or plaster (lime or cement, sand, and water) applied over an "armature" of metal mesh, woven, expanded metal, or metal-fibers, and closely spaced thin steel rods such as rebar. The metal commonly used is iron or some type of steel, and the mesh is made with ...
Water weight, also known as water retention, is a buildup of excess water or fluid in the body's tissues, which can occur for a variety of reasons, Dr. Felice Schnoll-Sussman, gastroenterologist ...
The inclusion of PCBs as a PBT may be attributed to their low water solubility, high stability, and semi-volatility facilitating their long range transport and accumulation in organisms. [5] The persistence of these compounds is due to the high resistance to oxidation, reduction, addition, elimination and electrophilic substitution. [6]
Metal toxicity or metal poisoning is the toxic effect of certain metals in certain forms and doses on life.Some metals are toxic when they form poisonous soluble compounds. . Certain metals have no biological role, i.e. are not essential minerals, or are toxic when in a certain for
Enhanced permeability and retention (EPR) effect and passive targeting. The enhanced permeability and retention (EPR) effect is a controversial concept [1] [2] by which molecules of certain sizes (typically liposomes, nanoparticles, and macromolecular drugs) tend to accumulate in tumor tissue much more than they do in normal tissues.
Concrete is a mixture of coarse (stone or brick chips) and fine (generally sand and/or crushed stone) aggregates with a paste of binder material (usually Portland cement) and water. When cement is mixed with a small amount of water, it hydrates to form microscopic opaque crystal lattices encapsulating and locking the aggregate into a rigid shape.
Other causes are acquired, such as cervical stenosis, intrauterine adhesions, endometrial cancer, and cervical cancer. [ 3 ] Additionally, hematometra may develop as a complication of uterine or cervical surgery such as endometrial ablation , where scar tissue in the endometrium can "wall off" sections of endometrial glands and stroma causing ...
The advantage of ferrocement construction is that materials are cheap and readily available, while the disadvantages are that construction labor costs are high, as are operating costs. (Ferrocement ships require thick hulls, which results in either a larger cross-sectional area that hurts hydrodynamics, or leaves less space for cargo.)
