Reactivity series

The reactivity series ALLOWS us to predict how metals will react. A more reactive metal will displace a less reactive metal from a compound. Rusting is an oxidation reaction.

The reactivity series

In a reactivity series, the most reactive element is placed at the top and the least reactive element at the bottom. More reactive metals have a greater tendency to lose electrons and form positive ions.

A reactivity series of metals could include any elements. For example:A good way to remember the order of a reactivity series of metals is to use the first letter of each one to make up a silly sentence. For example: People Say Little Children Make A Zebra Ill CONSTANTLY SNIFFING Giraffes.

Observations of the way that these elements react with water, acids and steam enable us to put them into this series.

The tables show how the elements react with water and DILUTE acids:

Element Reaction with water

Potassium Violently

Sodium Very quickly

Lithium Quickly

Calcium More slowly

Element Reaction with dilute acids

Calcium Very quickly

Magnesium Quickly

Zinc More slowly

Iron More slowly than zinc

Copper Very slowly

Silver Barely reacts

Gold Does not react

Note that aluminium can be difficult to place in the correct position in the reactivity series during these experiments. This is because its protective aluminium oxide layer makes it appear to be less reactive than it really is. When this layer is REMOVED, the observations are more reliable.

Non-metals in the reactivity series

It is useful to place carbon and hydrogen into the reactivity series because these elements can be used to extract metals.

Here is the reactivity series including carbon and hydrogen:

A list of elements from most reactive to least reactive: potassium, sodium, lithium, calcium, magnesium, aluminium, carbon, zinc, iron, hydrogen, copper, silver and gold.

Note that zinc and iron can be displaced from their oxides using carbon but not using hydrogen. However, copper can be extracted using carbon or hydrogen.

Answer:

Length:---

Length is the most necessary measurement in everyday life, and units of length in many countries still REFLECT humanity's first elementary methods.  

The inch is a THUMB. The foot speaks for itself. The yard relates closely to a human pace, but also derives from two cubits (the measure of the forearm). The mile is in origin the Roman mille passus - a 'thousand paces', approximating to a mile because the Romans define a pace as two steps, bringing the walker back to the same foot. With measurements such as these, it is easy to explain how far away the next village is and to work out whether an OBJECT will get through a doorway.  

For the complex measuring problems of civilization - surveying land to register property rights, or selling a commodity by length - a more precise unit is required.  

The solution is a rod or bar, of an exact length, kept in a central public place. From this 'standard' other identical rods can be copied and distributed through the community. In Egypt and Mesopotamia these standards are kept in temples. The basic unit of length in both civilizations is the cubit, based on a forearm measured from elbow to tip of middle finger. When a length such as this is standardized, it is usually the king's dimension which is first taken as the norm.  

Weight  :---

For measurements of weight, the human body provides no such easy approximations as for length. But nature steps in. Grains of wheat are reasonably standard in size. Weight can be expressed with some degree of accuracy in terms of a number of grains - a measure still used by jewellers.  

As with measurements of length, a lump of metal can be kept in the temples as an official standard for a given number of grains. Copies of this can be cast and weighed in the balance for perfect accuracy. But it is easier to deceive a customer about weight, and metal can all too easily be removed to distort the scales. An inspectorate of weights and MEASURES is from the start a practical necessity, and has remained so.

The thermosphere is the layer in the Earth's atmosphere directly above the MESOSPHERE and below the exosphere. Within this layer of the atmosphere, ultraviolet radiation causes photoionization/photodissociation of molecules, creating ions in the ionosphere. Taking its name from the Greek θερμός (pronounced thermos) meaning heat, the thermosphere begins at about 80 km (50 mi) above sea level.[1] At these high altitudes, the residual atmospheric gases sort into strata according to molecular mass (see turbosphere). Thermospheric temperatures increase with altitude due to absorption of highly energetic solar radiation. Temperatures are highly dependent on solar activity, and can rise to 1,700 °C (3,100 °F) or more. Radiation causes the atmosphere particles in this layer to become electrically charged (see ionosphere), enabling radio waves to be refracted and thus be received beyond the HORIZON. In the exosphere, BEGINNING at about 600 km (375 mi) above sea level, the atmosphere turns into space, ALTHOUGH by the criteria set for the definition of the Kármán line, the thermosphere itself is part of space.

The highly diluted gas in this layer can reach 2,500 °C (4,530 °F) during the day. Despite the high temperature, an OBSERVER or object will experience cold temperatures in the thermosphere, because the extremely low density of gas (practically a hard vacuum) is insufficient for the molecules to conduct heat. A normal thermometer will read significantly below 0 °C (32 °F), at least at night, because the energy lost by thermal radiation would exceed the energy acquired from the atmospheric gas by direct contact. In the anacoustic zone above 160 kilometres (99 mi), the density is so low that molecular interactions are too infrequent to permit the transmission of sound.

The dynamics of the thermosphere are dominated by atmospheric tides, which are driven by the very significant diurnal heating. Atmospheric waves dissipate above this level because of collisions between the neutral gas and the ionospheric plasma.

The International Space Station orbits the Earth within the middle of the thermosphere, between 330 and 435 kilometres (205 and 270 mi).

Explanation:

Nerve cord is a term that can refer to either (1) the single, hollow, fluid-filled, dorsal tract of nervous tissue that is one of the defining characteristics of chordates (dorsal nerve cord) and develops into the spinal cord and brain of vertebrates; or (2) the typically solid, ventral, double row of nerve fibers found in some phyla of invertebrates (ventral nerve cord).

In both cases, the term nerve cord references a bundle of nerve fibers that transverse the longitudinal axis of an animal and is an important structure of the animal's central nervous system. However, in the case of chordates, the nerve cord is tubular, hollow, fluid-filled, and runs dorsally, above the notochord and gut tract, while in the case of non-chordates it is solid and runs ventrally, below the digestive tract. They also differ in that the nerve cord of chordates forms by invagination in the embryo, whereas in non-chordates, the nerve cord does not form by invagination.

The fact that all chordates, as diverse as they are (from tunicates to hagfish to fish to birds to apes), share the presence of a dorsal nerve cord at some point in their life cycle shows the interconnectedness and unity of nature, as well as and evidence for a common descent. Likewise, the sharing of a ventral nerve cord among species of particularly invertebrate phyla shows the unity within these taxon.

Ventral nerve cord

Cross section of an earthworm showing the central nerve cord (n.c.), as well as the body wall (w); membranes (c) that divide the body cavity into a series of chambers; a COILED nephridium (n); the intestine (i); and above and below it a longer blood vessel (v).

The ventral nerve cord is a bundle of nerve fibers, typically a solid double stand (pair) of nerve cords, that runs along the longitudinal axis of some phyla of elongate invertebrates, and forms part of the invertebrate's central nervous system. In most cases, this nerve cords runs ventrally, below the gut, and connects to the CEREBRAL ganglia. Among the phyla exhibiting ventral nerve cords are nematodes (roundworms), annelids (such as earthworms, and arthropods (such as insects and crayfish).

The ventral nerve cord usually consists of a pair of partially fused nerve trunks running longitudinally along the ventral plane of the animals, from the anterior to posterior (the thoracic and abdominal tagma in the arthropods). A basic structure, for example, is the scenario where each body segment is innervated by pairs of ganglia (or it can be described as each segment having one ganglia but that ganglia consists of a pair of hemiganglia on either side). Ganglia of adjacent SEGMENTS are connected by nerve fibers designated as connectives (or "intersegmental connectives"). Within a segment, the hemiganglia are connected by a tract of nerve fibers, called commissures, that pass from one side to the other of the nerve cord. The complete system bears some likeness to a rope ladder.

There are different degrees of fusion of the ganglia among different taxon. In some animals, the bilateral ganglia are fused into a single large ganglion per segment. This characteristic is found mostly in the insects.

Unlike with chordates, the nerve cord in invertebrates does not develop by invagination. Rather than the cells gathering dorsally on the embryo's outer surface, FOLDING inward, and then sinking to their final position, in the case of the ventral nerve cord's formation, the cells commonly move inward to the internal position individually (Campbell ET al. 2013).

Pollution Control

Ricardo Beiras, in Marine Pollution, 2018

18.4 Regulations for Complex Effluents and Depuration of Waste Waters

Complex effluents are CHARACTERIZED on the basis of general parameters (Biological Oxygen Demand [BOD], suspended solids [SS], nutrients) and presence of priority substances

Point-source control of pollution is based on emission standards the discharges must meet to be authorized. These standards ADDRESS general water quality parameters such as Biological Oxygen Demand (BOD), suspended solids (SS), or nutrients. In addition, specific legislation may target priority substances, such as trace metals or persistent ORGANICS (POPs), whose presence in the discharges may be restricted to maximum levels or prohibited. In Canada, current regulations include testing acute lethality of the effluent to rainbow trout.21

The US Clean Water Act, derived from the 1948 Water Pollution Control Act, was designed to control the point-source discharge of effluents into surface waters. Effluent standards are set for categories of existing sources, including WWTP, and permits of discharge are issued for emissions provided the discharges meet those performance standards. The standards are issued by EPA on the basis, not of ecotoxicological impact or risk assessment, but on the application of the best available technology each type of source can achieve.

In Europe, the protection of the environment from the adverse effects of urban waste water discharges is addressed in DIRECTIVE 91/1971, (later amended by Directive 98/15/EC) which enforces appropriate collection, secondary treatment for all emissions above 2000 inhabitant equivalents, and additional treatment for nutrient removal for emissions to areas sensitive to hypereutrophication. Also, compliance with general emission standards for BOD (See Table 2.2), Chemical Oxygen Demand (COD), SS, and for sensitive areas, nutrients (see Table 3.1) is required. In addition, Directive 2006/11 issues two lists of priority substances (see Section 18.1) termed dangerous substances, whose emission must be subjected to a previous permit and according to substance-specific emission standards. List I, substances whose pollution in the water should be eliminated, include organohalogens and organophosphates, organotin compounds, Hg, Cd, mineral oil, and petroleum hydrocarbons, carcinogenic and persistent floating substances interfering with navigation, leisure, or other uses of water. List II, whose pollution in the water should be reduced, includes a wide array of trace elements and organic chemicals. The lists are similar to the black and gray lists from the 1972 London Convention (see Table 18.1).

While we’re showing a 3M™ Littmann® Cardiology III™ Stethoscope in these examples, please note that all current Littmann stethoscopes (with the exception of electronic models) have similar components.

Chestpiece

Some Littmann stethoscope models have a one-sided chestpiece with a tunable diaphragm. Others have a two-sided chestpiece with a diaphragm on one side and a bell on the other. Some bells are always open, others are closed with a tunable diaphragm, depending on the model.

The larger diaphragm side is normally USED for adult patients. The smaller-diameter bell is best for pediatric or thin patients, for maneuvering around bandages, and for carotid assessment. The closed bells on Littmann stethoscopes can be converted to traditional open bells by replacing the diaphragm with a nonchill bell sleeve or rim.

The stem connects the stethoscope tubing to the chestpiece. On Littmann stethoscopes with two-sided chestpieces, there can only be one acoustic path from the diaphragm to the eartips. ROTATING the two-sided chestpiece on the stem selects or “indexes” which diaphragm is open to the acoustic path.

Tunable Diaphragm

The tunable diaphragm is a 3M invention that can make auscultating a patient easier. It lets you easily hear different sounds simply by adjusting the pressure on the chestpiece. Here’s how a tunable diaphragm works:

Tubing

Current Littmann stethoscopes feature next-generation tubing that provides improved resistance to skin oils and alcohol for longer tubing life. No natural rubber latex or phthalate plasticizers are used in the tubing or any other component—to help protect human health and the environment. All Littmann Cardiology stethoscopes have double lumen tubing: two sound paths inside one outer tube which helps eliminate the rubbing noise generated by traditional twin-tubed stethoscopes.

Headset and Eartubes

The headset is made up of two eartubes, tension springs and the eartips.

The eartubes are positioned at an anatomically correct angle, for a proper fit into your ear CANALS. The ribbed ends of the eartubes snap the eartips on tight for safety. Eartubes on a Littmann stethoscope are made of an aerospace aluminum alloy that provides both strength and lighter weight.

The headset tension is adjusted for individual fit and comfort by pulling the eartubes apart to reduce the tension, or squeezing them together (crossing them over) to increase tension.

Eartips

All Littmann stethoscopes are fitted with eartips that snap tight onto the eartubes for safety. (In fact, they require some effort to remove.) The durable, soft-sealing eartips provide an excellent acoustic seal and comfortable fit. The eartips are available in small and large sizes, and black and gray versions. Many Littmann stethoscope models come with an extra set of soft-sealing eartips and a pair of firm TIPS.
