What navigational aids did the Muslims develop?
Muslim scientists compiled their knowledge of seasonal weather, tides, prevailing winds, sea currents as well as astral-navigation to create navigational tools. These tools included astronomical tables and navigational tables for navigators. They are responsible for the invention of the Astrolab, as well as innovations in cartography.
What is fatigue limit?
Fatigue limit which can also be known as an endurance limit or a breaking limit. A fatigue limit is a measure of the totalamount of stress a material can repeatedly withstandor tolerate before failing or breaking. All categories of materials have some kind of fatigue load limit. Materials are tested carefully to make sure that they meet standards for use in specialised products, anapproach that aids to prevent losses or damages arising from using materials that are unsuitablefor the construction of the finished product.
What are Three functions of the electrode covering in manual metal arc mma welding?
3 FEATURES OF FLUX CORED ELECTRODES Flux cored electrodes combine the advantages of several of the welding processes we have discussed earlier. As with coated electrodes, the flux improves the weld metal chemi- cal composition and mechanical properties. As in gas metal arc welding and submerged arc welding, productivity is increased because the electrode is continuous. 7.3.0.1 Flux cored electrodes may be used for welding carbon steels, low alloy high strength steels, and the high strength quenched and tempered steels. They are also used for welding stainless steels and abrasion resistant steels. These will be covered in subse- quent lessons. 7.3.1 Functions of the Flux Ingredients - As with coated ingredients, each manufac- turer has his own formulas for the flux ingredients. The composition of the flux core can be varied to provide electrodes for specific applications. 7.3.1.1 The basic functions of the flux ingredients are: a) Deoxidizers and Denitrifiers - Since nitrogen and oxygen can cause porosity or brittleness, deoxidizers such as manganese and silicon are added. In the case of self-shielded electrodes, denitrifiers such as aluminum are added. Both help to purify the weld metal. b) Slag Formers - Slag formers such as oxides of calcium, potassium, silicon or so- dium are added to protect the molten weld puddle from the atmosphere. The slag aids in improving the weld bead shape and "fast freezing" slags help hold the weld puddle for out-of-position welding. The slag also retards the cooling rate, especially important when welding the low alloy steels. c) Arc Stabilizers - Elements, such as potassium and sodium, help produce a smooth arc and reduce spatter. d) Alloying Elements - Alloying elements, such as molybdenum, chromium, carbon, manganese, nickel, and vanadium, are used to increase strength, ductility, hardness and toughness. e) Gasifiers - Minerals, such as fluorspar and limestone, are usually used to form a shielding gas in the self-shielded type wires.
Diffusion of AIDS is an example of which type of diffusion?
Diffusion of AIDS is an example of contagious diffusion, where the disease spreads through direct or indirect contact between individuals.
A disease that involves a defect in the cell-mediated immunity system?
AIDS- acquired immune deficiency syndrome

A disease that involves a defect in the cell-mediated immunity system is?
A defect in the cell-mediated immune system response was identified with regard to Hepatitis B (with many articles written about this in 2008-2009). HIV-AIDS is another disease with a defect in cell-mediated immune response, as well. There are other immunodeficiency diseases involving this kind of defect, too. immunological deficiency syndroms
What hormone aids the diffusion of glucose across the cell membrane?
Insulin is the hormone that aids in the diffusion of glucose across the cell membrane by facilitating the uptake of glucose into cells, particularly in muscle and fat tissue. In the absence of insulin or in conditions of insulin resistance, glucose uptake is impaired, leading to high blood sugar levels.
What is auditory defect?
Auditory defect refers to any impairment or dysfunction in the auditory system that affects a person's ability to hear. This can range from mild hearing loss to complete deafness, and can be caused by a variety of factors such as genetics, illness, injury, or exposure to loud noise. Treatment options may include hearing aids, cochlear implants, or other interventions, depending on the type and severity of the defect.
What aids in diffusion and in cell recognition?
Proteins play a key role in aiding diffusion across cell membranes by acting as channels or carriers. Cell recognition is facilitated by cell surface markers such as glycoproteins and glycolipids, which help cells identify and communicate with each other.

What inorganic substance aids in the diffusion of gases through a cellular membrane?
Inorganic substances such as phospholipids aid in the diffusion of gases through cellular membranes. Phospholipids make up the structure of cell membranes, providing a barrier that allows selective permeability of gases like oxygen and carbon dioxide. These phospholipids have a hydrophobic tail and a hydrophilic head, creating a bilayer that facilitates the diffusion of gases across the membrane.
