Background information on miticides, antibiotics, and neonicotinoid pesticides Neonicotinoid pesticides are commonly used in various parts of the world. This group of pesticides assume the model of nicotine which is a natural insecticide. Neonicotinoid pesticides act on the central nervous establishment (CNS) of insects causing excitation of nerves and finally, paralysis. evidence from research has revealed that the use of pesticides like neonicotinoid pesticides and nicotine-based pesticides greatly affects the functioning and learning abilities of honeybees. This is very critical to the workers since they are the around active and dependable members of a colony. According to Gary et al (2009), it has been documented that neonicotinoid pesticides levels that are able to affect the energy learning of bees occur in pollen hence they affect bees that feed on such pollen. There is an increase threat on honeybees and their store by mites and this has increased the dependence on miticides in order to check into the situation. Basically, miticides are used in agriculture, to control the spread of mites. This is important because mites have a key manipulation to play in the loss of good health among honeybees. However, the intensive use of these miticides has led to the development of their tube by mites. To add an injury to this, toxicity tests conducted on bee hives have revealed that the levels of miticides in many bee hives has greatly increased (Mullen et al, 2010). Miticides are destructive to colonies of bees because they stack up in bees wax. Bees wax is a least renewable resource in the hive hence it provides a base on which persistent pesticides can accumulate and cause toxic house syndrome (Mullen et al, 2010). In modern medicine, antibiotics are among the medications that are prescribed most frequently. Antibiotics are important for both animals and plants because they kill or injure disease-causing bacteria. However, it has been found that their use contribute to deficiencies of the immune system while their prolonged use lead to antibiotic resistant diseases and super-pests. Many commercial beekeepers administer antibiotics on regular basis as a protective measure against brood diseases hence honeybees have not been exempted from the effects of prolonged use of antibiotics. It has been found out that the major bacterial diseases that attack bees have excessively developed resistance to antibiotics. Resistance to pesticides has triggered the development of genetically modified crops that are thought to be producing pollen that also cause CCD (Gary et a l, 2009. Potential Causes of Colony Collapse Disorder (CCD) The causes of CCD are still under investigation and or so every realistic and conceivable cause is a possibility. Four areas of research focused on by scientists in betimes times included bee management stresses such as poor nutrition, environment-related stresses, parasites and pathogen, and pesticides and chemicals.

Mars weather can create dust devils from the warming of the sun the hot air rises meeting the cold air to make Martian dust devils that can reach 8 km high. Also at certain times the wind can lift giant clouds of dust off the surface engulfing the planet in a globe dust storm.

Has the role of preparing and creating curriculum plans for the staff to carry out in the Early Childhood Care and Education setting.Making sure that there is good staff morale, resolving any issues that arise promptly and effectively Making sure that there the Child Protection policy is being promoted and that the policy is being firmly stuck to. If any concerns are arisen then the manager must document and record this. Organise meetings with parents throughout the year to inform them and discuss such things as the childs overture and alsoadhering to any concerns raised by the parents. It is also a role and respon sibility of the manager to take a crap and organise special event and outings for the children attending the Early Childhood Care and Education setting. ( class notes)The preschool manager must have a minimum qualification of level of seven/eight in childcare.This qualification can be obtained in most ITs. The duration of study that it would take to obtain this would be approximately three to four years depending on the level of qualification. To then further become a pre-school manager the level of experience the individual would need to have would depend on the Early Childhood Care and Education setting. Generally the minimum experience needed by the individual would be approximately two four years. It would be appropriate that the individual had experience as a supervisor before decent a pre-school manager.Employment and Career Opportunities in ChildcareFunding that is made available to state to childcare services, such as the Equal Opportunities Childcare Programme, the Early Childhood Care and Education Scheme / Free Pre-School year and Community Childcare Solovention scheme make the option of childcare services more appealing and therefore increase the demand for childcare services. As a result of the increased demand for childcare services, the demand for employment opportunities also increases.The Early Childhood care and Education Scheme / Free Pre-school year (FPSY) was introduced in 2009. The scheme recognized the importance of qualifications within the childcare sector and as a result it introduced a minimum qualifications standard for pre-school leaders. An important feature of the scheme is that it offers more funding for better hooked staff and because of this feature it can increase or decrease an individuals employment opportunities e.g. if an individual applied for a particular position in which the state requires the potential employee to hold a level 7 qualification, and the candidate did not hold a Level 7 qualification,that candidate will most likely not get the position as a result as their employment would not benefit the pre-school.The Community Childcare Subvention Scheme is a support scheme that was set up to aid and support non-profit childcare services/centres. This scheme does not support profit childcare services. The schemes main focus is to help the non-profit childcare services. This scheme allows non-profit childcare services to provide their services at a lower rate, which enables children with disadvantaged parents the opportunity to attend childcare services.Each Community based service that takes part in the Community Childcare scheme, has the responsibility to make a guideline available of the different place for each type of service that they offer to parents. There are four types of fee rates available and the parent/guardian will be offered the rate depending on what price band or category they fall into based on their individual financial situation. This scheme enables more access to all types of parents and therefore increases the demand for childcare services and effectively increases employment opportunities.Special Needs Assistant Due to the downswing in the Irish Economy, there have been substantial cuts in Special Needs Assistants. It has been revealed that approximately 1200 Special needs assistant positions will be cut in the near future. (Class notes) If this happens, there will be a sharp decrease in the amount of employment opportunities available within the childcare sector. It is also thought that as a result of the cuts, individuals that currently hold a Level 7/8 qualification may not be willing to apply for job opportunities that become available due to the poor pay conditions and low status of the childcare positions.Progression of qualifications within the childcare sector e.g. achieving a Level 5 and progressing to a Level 6, Level 7 and Level 8 qualification is fit more important to childcare workers to help them increase their employment oppor tunities. The better the qualification that a childcare worker obtains means they have a high chance of securing employment within the childcare sector. E.g. If an advertizing is published in a newspaper for a childcare position, and an individual that holds a Level 5 applieswhile also an individual what holds a Level 8 qualification also applies, the individual with the higher qualification i.e. the Level 8 qualification, will have a higher chance of getting the position. after(prenominal) obtaining a Level 8 qualification i.e. A Degree in childcare, which is generally obtained over a three year period, there is a career opportunity to continue to study towards a Primary school teaching qualification. A further two years of study in Teacher raising is also required before obtaining a qualification as a Primary school teacher. later achieving a minimum of a Level 7/8 qualification, there is also the opportunity to become a manager within a childcare setting. An individual seeking to further their career or who wishes to pursue a career in management would also need sufficient experience within the early childcare and education setting to secure a higher position. This career opportunity can only become available for the individual if they have obtained a Level 7/8 qualification.

Supply Chain Management and Lean Production Essay Example for Free

Supply Chain Management and bleed Production EssayAbstract The system of interconnected bloodes used to push a product from provider to consumer is delineate as a bring out range. Supply drawing string management focuses on managing the put out strand in an effort to improve the quality and time it requires to manufacture a product. In addition to implementing planning chain management, a helpful lean production practice called Just-in-time can be used to move out any waste present along the affix chain.The marriage of lean production and tally chain management creates lean supply chain management, which provides a much leaner and more economical supply chain for the product to flow by means of. Supply Chain Management and Lean Production Much incredulity about what supply chain management entails is present in todays society. Many bulk treat supply chain management as being synonymous with logistics, which is the management of the flow of goods from the stemma to the consumersHowever, supply chain management encompasses much more than the purchasing or management of goods to the consumer. Supply chain management (SCM), as defined by Lambert (2008), is the management of relationships a tangle the supply chain, which includes a interlocking of interconnected businesses twisty in providing a product or service to the consumer. The management of the relationships in the midst of businesses on the supply chain is significant to ensure successful and efficient processes are used in providing products and goods to the customer. translation of Supply Chain Management (SCM)What is a supply chain? A supply chain is defined as a system of organizations, as well as people and information, which are directly involved with the manufacture and delivery of a product (Phelps, Smith, Hoenes, 2004 Supply Chain, 2008). The supply chain includes the transformation of raw materials at the site of the supplier to finished goods that can be used by the consu mer, as shown in ikon 1. The path the product travels is similar to that of a river. A river, when properly banked, is flowing in one boot towards a goal (Tompkins, 2000).Mark Twain stated that Without banks the river is just a puddle. A supply chain, uniform a river, needs communication and integration as its banks to create a force towards the destination, which is the consumer. Without the presence of the banks, the river would go nowhere and therefore be merely a puddle. Effective communication in business relationships that cross over different departments, as displayed by the arrows in Figure 1, is necessary to provide quality products to the consumer. What is supply chain management?Lambert (2004) defines supply chain management as the integration of key business processes from the end user through original suppliers than provides products, services, and information that add value for customers and other stakeholders. An illustration of supply chain management is display ed in Figure 2. This figure represents a basic supply chain net income structure, as well as the flow of information and the product. The eight supply chain management processes, which mingle various tasks at bottom the organization across the supply chain, can also be found in Figure 2 (Lambert, 2008).The implementation of the eight supply chain management processes is necessary to manage the relationships between various departments and tasks across the supply chain. Supply chain management is ultimately about the management of relationships within the network of businesses in the supply chain. Lambert (2008) expresses that the management of a supply chain is managed link-by-link, relationship-by-relationship, and the organizations that manage these relationships stovepipe will win. Role of Supply Chain Management (SCM) Overview of the roleSupply chain management places forethought along the entire supply chain, from raw materials at the supplier to finished goods in the han ds of the customer. single role that supply chain management plays within a company is producing more efficient, quality products, which creates a competitive advantage among other companies. Today, management of the supply chain can be completed through the use of supply chain management software, such as E2Open. Supply chain management allows a company to document and track data pertaining to the supply chain. Benefits of the supply chain managementSupply chain management places importance on managing the customer relationship, as well as the supplier relationship. By efficaciously managing these relationships, the company can become more competitive, while increasing the quality of the product to the customer. Placing emphasis on the supplier relationship and the businesses along the supply chain increases product efficiency and quality. The importance placed on the customer relationship focuses on the demands and needs of the customer. Through effective communication within th e relationships along the supply chain, a basic balance of supply and demand is established.

electric automobile automobile Generator EssayEarly 20th century alternator do inBudapest, Hungary, in the agent generating h every of a hydroelectric station In electrical energy generation, an electric writer is a device that converts mechanised free energy to electrical energy. A beginning forces electric constitute (usually carried by electrons) to f low by an orthogonal electrical circuit. The citation of mechanical energy may be a reciprocating or turbine steam engine, water move finished a turbine or waterwheel, aninternal combustion engine, a wind turbine, a hand crank, compressed air, or either opposite source of mechanical energy. Generators supply almost all of the cater for the electric federal agency storage-battery grids which provide most of the worlds electric military groupfulness. The reverse conversion of electrical energy into mechanical energy is done by an electric ride, and motors and seeds have umteen similarities. Many motors ca n be automatically driven to take electricity and frequently make acceptable roots.HistoryBefore the connection in the midst of drawism and electricity was discovered, static generators were used. They operated on electrostaticprinciples. Such generators generated very high voltage and low current. They operated by using base electrically charged belts, plates, and disks that carried charge to a high potential electrode. The charge was generated using either of both mechanisms* Electrostatic instalment* The triboelectric effect, where the contact between two insulators leaves them charged. Be puzzle of their inefficiency and the difficulty of insulating weapons that produced very high voltages, electrostatic generators had low power ratings, and were never used for generation of commercially significant quantities of electric power. The Wimshurst machine and forefront de Graaff generator atomic number 18 examples of these machines that have survived. In 1827, Hungarian A nyos Jedlik started expe lineenting with the electro magnetized rotating devices which he called electro magnetized self-rotors, nowadays called the Jedliks dynamo.In the paradigm of the single-pole electric starter (finished between 1852 and 1854) both the stationary and the revolving parts were electromagnetic. He formulated the concept of the dynamo at least 6 years beforeSiemens and Wheatst cardinal completely if didnt patent it as he view he wasnt the prime(prenominal) to realize this. In essence the concept is that instead of permanent magnets, two electromagnets opposite to each other induce the magnetic field around the rotor. It was as well as the discovery of the principle of self-excitation.1Faraday disk, the starting time electric generator. The horseshoe-shaped magnet (A) created a magnetic field through the disk (D). When the disk was turned, this generate an electric current radially outward from the center toward the rim. The current flowed out through the sli ding spring contact m, through the external circuit, and back into the center of the disk through the axle. In the years of 18311832, Michael Faraday discovered the operating principle of electromagnetic generators. The principle, later called Faradays law, is that an electromotive force is generated in an electrical conductor which encircles a variable magnetic flux. He also built the first electromagnetic generator, called the Faraday disk, a type of homopolar generator, using a copper disc rotating between the poles of a horseshoe magnet. It produced a small DC voltage.This design was inefficient, due to self-cancelling counterflows of current in regions that were non under the figure out of the magnetic field. While current was induced directly underneath the magnet, the current would sprinkle backwards in regions that were outside the influence of the magnetic field. This counterflow limited the power output to the pickup wires, and induced waste heating of the copper disc. subsequently homopolar generators would solve this problem by using an array of magnets logical around the disc perimeter to maintain a steady field effect in one current-flow direction.Another disadvantage was that the output voltage was very low, due to the single current path through the magnetic flux. Experimenters found that using fivefold turns of wire in a coil could produce higher, more than useful voltages. Since the output voltage is proportional to the number of turns, generators could be easily designed to produce any desired voltage by varying the number of turns. Wire windings became a basic feature of all subsequent generator designs.Dynamos ar no longer used for power generation due to the size and complexity of the commutator needed for high power applications. This thumping belt-driven high-current dynamo produced 310 amperes at 7 volts, or 2,170 watts, when spinning at 1400 RPM.Dynamo Electric Machine End View, Partly Section (U.S. Patent 284,110) The dyna mo was the first electrical generator capable of delivering power for industry. The dynamo uses electromagnetic stimulus generalization to convert mechanical rotation into direct currentthrough the use of a commutator. The first dynamo was built by Hippolyte Pixii in 1832. A dynamo machine consists of a stationary structure, which provides a constant magnetic field, and a typeset of rotating windings which turn within that field. On small machines the constant magnetic field may be provided by one or more permanent magnets medium- sizabler machines have the constant magnetic field provided by one or more electromagnets, which are usually called field coils. Through a serial of accidental discoveries, the dynamo became the source of many later inventions, including the DC electric motor, the AC alternator, the AC synchronous motor, and the rotary converter. jump current generating systems were known in simple forms from the discovery of the magnetic induction of electric current. The early machines were au becausetic by pioneers such as Michael Faraday and Hippolyte Pixii. Faraday developed the rotating rectangle, whose operation was heteropolar each active conductor passed successively through regions where the magnetic field was in opposite directions.2 The first public induction of a more productive alternator system took place in 1886.3 Large two- mannikin alternating current generators were built by a British electrician, J.E.H. Gordon, in 1882. Lord Kelvin andSebastian Ferranti also developed early alternators, producing frequencies between 100 and 300 Hz. In 1891, Nikola Tesla patented a practical high- absolute frequency alternator (which operated around 15 kHz).4After 1891, polyphase alternators were introduced to supply currents of multiple differing phases.5 Later alternators were designed for varying alternating-current frequencies between sixteen and about one hundred hertz, for use with arc lighting, incandescent lighting and electric moto rs.6 Large power generation dynamos are now rarely seen due to the now nearly universal use of alternating current for power distribution. Before the adoption of AC, very large direct-current dynamos were the only means of power generation and distribution. AC has come to dominate due to the ability of AC to be easily converted to and from very high voltages to permit low losses over large distances. Electromagnetic generatorsDynamo primary(prenominal) article DynamoDynamo Electric Machine (end view, partly section, U.S. Patent 284,110) A dynamo is an electrical generator that produces direct current with the use of a commutator. Dynamos were the first electrical generators capable of delivering power for industry, and the foundation upon which many other later electric-power conversion devices were establish, including the electric motor, the alternating-current alternator, and the rotary converter. Today, the simpler alternator dominates large scale power generation, for efficien cy, reliability and toll reasons. A dynamo has the disadvantages of a mechanical commutator. Also, converting alternating to direct current using power rectification devices (vacuum supply or more recently solid call down) is effective and usually economic.AlternatorMain article AlternatorWithout a commutator, a dynamo becomes an alternator, which is a synchronous singly feed generator. Alternators produce alternating current with a frequency that is based on the rotational facilitate of the rotor and the number of magnetic poles. Automotive alternators produce a varying frequency that changes with engine speed, which is then converted by a rectifier to DC. By comparison, alternators used to feed an electric power grid are generally operated at a speed very close to a specific frequency, for the benefit of AC devices that regulate their speed and performance based on grid frequency. round devices such as incandescent lamps and ballast-operated fluorescent lamps do not require a constant frequency, but synchronous motors such as in electric wall clocks do require a constant grid frequency.When attached to a larger electric grid with other alternators, an alternator will dynamically interact with the frequency already present on the grid, and operate at a speed that matches the grid frequency. If no driving power is applied, the alternator will continue to spin at a constant speed anyway, driven as a synchronous motor by the grid frequency. It is usually necessary for an alternator to be accelerated up to the correct speed and phase alignment before connecting to the grid, as any twin in frequency will cause the alternator to act as a synchronous motor, and suddenly rise to the correct phase alignment as it absorbs a large inrush current from the grid, which may upon the rotor and other equipment.Typical alternators use a rotating field winding excited with direct current, and a stationary (stator) winding that produces alternating current. Since the ro tor field only requires a tiny fraction of the power generated by the machine, the brushes for the field contact can be relatively small. In the grapheme of a brushless exciter, no brushes are used at all and the rotor shaft carries rectifiers to excite the main field winding. edit inference generatorMain article induction generatorAn induction generator or asynchronous generator is a type of AC electrical generator that uses the principles of induction motors to produce power. Induction generators operate by mechanically turning their rotor faster than the synchronous speed, giving ostracize slip. A regular AC asynchronous motor usually can be used as a generator, without any internal modifications. Induction generators are useful in applications such as minihydro power plants, wind turbines, or in simplification high-pressure gas streams to lower pressure, because they can recover energy with relatively simple controls. To operate an induction generator must be excited with a le ading voltage this is usually done by connection to an electrical grid, or sometimes they are self excited by using phase correcting capacitors. editMHD generatorMain article MHD generatorA magnetohydrodynamic generator directly extracts electric power from pitiable hot gases through a magnetic field, without the use of rotating electromagnetic machinery. MHD generators were originally developed because the output of a plasma MHD generator is a flame, well able to heat the boilers of a steam power plant. The first practical design was the AVCO Mk. 25, developed in 1965. The U.S. government funded substantial development, culminating in a 25 MW demonstration plant in 1987. In the Soviet Union from 1972 until the late 1980s, the MHD plant U 25 was in regular commercial operation on the Moscow power system with a rating of 25 MW, the largest MHD plant rating in the world at that time.7 MHD generators operated as a topping cycle are currently (2007) less efficient than combined cycle g as turbines. editOther rotating electromagnetic generatorsOther types of generators, such as the asynchronous or induction singly fed generator, the twice fed generator, or the brushless wound-rotor doubly fed generator, do not incorporate permanent magnets or field windings that establish a constant magnetic field, and as a result, are seeing success in variable speed constant frequency applications, such as wind turbines or otherrenewable energy technologies. The full output performance of any generator can be optimized with electronic control but only the doubly fed generators or the brushless wound-rotor doubly fed generator incorporate electronic control with power ratings that are substantially less than the power output of the generator under control, a feature which, by itself, offers cost, reliability and efficiency benefits.Homopolar generatorMain article Homopolar generatorFaraday disk, the first homopolar generatorA homopolar generator is a DC electrical generator compr ising an electrically conductive disc or cylinder rotating in a plane perpendicular to a uniform static magnetic field. A potential difference is created between the center of the disc and the rim (or ends of the cylinder), the electrical polaritydepending on the direction of rotation and the orientation of the field. It is also known as a unipolar generator, acyclic generator, disk dynamo, orFaraday disc. The voltage is typically low, on the order of a few volts in the case of small demonstration models, but large research generators can produce hundreds of volts, and some systems have multiple generators in series to produce an even larger voltage.8 They are unusual in that they can source tremendous electric current, some more than a million amperes, because the homopolar generator can be made to have very low internal resistance.ExcitationA small early 1900s 75 KVA direct-driven power station AC alternator, with a separate belt-driven exciter generator. Main article Excitation ( magnetic) An electric generator or electric motor that uses field coils rather than permanent magnets requires a current to be present in the field coils for the device to be able to work. If the field coils are not powered, the rotor in a generator can spin without producing any usable electrical energy, while the rotor of a motor may not spin at all. Smaller generators are sometimes self-excited, which means the field coils are powered by the current produced by the generator itself. The field coils are connected in series or parallel with the armature winding.When the generator first starts to turn, the small amount of remanent magnetism present in the squeeze core provides a magnetic field to get it started, generating a small current in the armature. This flows through the field coils, creating a larger magnetic field which generates a larger armature current. This bootstrap process continues until the magnetic field in the core levels off due to saturation and the generator r eaches a steady state power output. Very large power station generators often utilize a separate little generator to excite the field coils of the larger. In the event of a severe widespread power outage where islanding of power stations has occurred, the stations may need to perform a black start to excite the field of their largest generators, in order to restore customer power service.Electrostatic generatorMain article electrostatic generatorA Van de Graaff generator, for class room demonstrationsAn electrostatic generator, or electrostatic machine, is a mechanical device that produces static electricity, or electricity at high voltage and lowcontinuous current. The knowledge of static electricity dates back to the earliest civilizations, but for millennia it remained merely an interesting and mystifying phenomenon, without a theory to explain its style and often confused with magnetism. By the end of the 17th Century, researchers had developed practical means of generating el ectricity by friction, but the development of electrostatic machines did not begin in earnest until the 18th century, when they became fundamental instruments in the studies about the new science of electricity.Electrostatic generators operate by using manual (or other) power to transform mechanical work into electric energy. Electrostatic generators develop electrostatic charges of opposite signs rendered to two conductors, using only electric forces, and work by using moving plates, drums, or belts to carry electric charge to a high potentialelectrode. The charge is generated by one of two methods either the triboelectric effect (friction) or electrostatic induction. editWimshurst machineMain article Wimshurst machineWimshurst machine with two Leyden jars.Suppose that the conditions are as in the figure, with the segment A1 positive degree and the segment B1 negative. Now, as A1 moves to the left and B1 to the right, their potentials will rise on account of the work done in separ ating them against attraction. When A1 and neighboring sectors comes opposite the segment B2 of the B plate, which is now in contact with the brush Y, they will cause a displacement of electricity along the conductor between Y and Y1 bringing a negative charge, larger than the positive charge in A1 alone, on Y and sending a positive charge to the segment touching Y1.As A1 moves on, it passes near the brush Z and is partially discharged into the external circuit. It then passes on until, on touching the brush X, has a new charge, this time negative, driven into it by induction from B2 and neighboring sectors. As the machine turns, the process causes exponential increases in the voltages on all positions, until sparking occurs limiting the increase. The Wimshurst influence machine is an electrostatic generator, a machine for generating high voltages developed between 1880 and 1883 by Britishinventor James Wimshurst (18321903). It has a distinctive appearance with two large contra-rota ting discs mounted in a vertical plane, two go across bars with alloylic brushes, and a spark gap formed by two metal spheres.Van de Graaff generatorMain article Van de Graaff generatorA Van de Graaff generator is an electrostatic generator which uses a moving belt to accumulate very high voltages on a hollow metal globe on the top of the stand. It was invented by American physicist Robert J. Van de Graaff in 1929. The potential difference achieved in modern Van de Graaff generators can reach 5 megavolts. The Van de Graaff generator can be thought of as a constant-current source connected in parallel with a capacitorand a very large electrical resistance, so it can produce a visible electrical discharge to a close grounding surface which can potentially cause a spark depending on the voltage.
