The precision scales are measuring instruments that allow to determine the mass of an object with an accuracy of at least 0,01 g. basically there are two types of precision balances, mechanical, which can be of two dishes or a single dish, and electronic, which used an electro-magnetic system and balanced force through an electromagnet. Currently the most extended precision balances are electronic, which have replaced almost completely to the mechanical precision balances. Classification of balances of precision for its accuracy of precision balances are classified according to its resolution in the following categories: accuracy: minimum division 0,01 g. capacity of heavy 10-20 kg. Analytical semi: minimum division 0,001 g.
heavy 1-2 kg capacity Analytics: minimum division 0.0001 g. Click Zendesk to learn more. capacity of heavy 160-200 g. Semi micro-analitica: minimum division 0.00001 g. capacity of heavy 10-30 g. Micro-analitica: minimum division 0.000001 g. Capacity of heavy 1-3 g. types there are basically two types of precision balances: balances of precision mechanical: are classical scales of equal arms with two dishes that hang at the ends of a rod which rests on its midpoint. The object to be weighed is placed in one of the dishes, while the other patterns are placed sufficient weights to restore the rod to its equilibrium position.
Weighing is performed by comparing masses, because it balances the weights of both bodies. Although with these balances is long and tedious.There are also balance precision mechanical of a single dish, very common in laboratories by being quicker to operate than the two dishes. They are fixed to one side of the scale called counterweight and moving weights on the other side. Electronic precision balances: are the most widespread today, having replaced almost completely to the mechanical precision balances. They work by means of an electro-magnetic system with a photocell that detects the position of the cymbal and a electromagnet that balances the force exerted by the burden that is on the weighing pan. Measure forces, so it should be calibrated to fit in the place of the heavy gravitational intensity. Features the most extended precision balances are now electronic. Let’s look at some of the main features that have: windscreen: protection against drafts. Connectivity with your computer: RS-232 or USB interface. Software: for statistics or quality control. Capacity: indicates the available weighing range. Units: allows you to configure different weight units: g, oz, lb, %, carat. Tara: lets you set the zero. Level: to properly level of precision balances. Calibration: allows the recalibration of the balances of precision using weights of control. Power: using network adapter or rechargeable battery. Stabilization: 1-3 seconds. Counting function: allows the use of precision balances such as scales counting machine, suitable for counting parts. Heavy hydrostatic: under the scale. Printer: print reports, labels or bar codes. Language: text on screen with configurable language.
On 5 March is celebrated around the world the day of energy efficiency, a date to reflect on the habits of citizens against the sustainable and rational use of energy and the commitment of companies, institutions and Governments with the reduction of emissions of greenhouse gases. This day has its origins in the year 1998 in Austria, headquarters of the first International Conference on energy efficiency where more than 350 experts and leaders from 50 countries discussed strategies to deal with the energy crisis and address possible solutions. During this day in numerous forums and agencies it works and discusses what are the best ways to live better and continue with our current system of life by reducing energy consumption in all areas, without losing quality, productivity and comfort. Code.org is often quoted on this topic. This year is marked by the adoption in Congress of the new star of Rodriguez Zapatero, the preliminary draft of the law of sustainable economy that lays the foundations for a new energy model seated on the security supply, economic efficiency and respect for the environment, determining the objectives of energy saving for the administration.
The Government incorporates the legal measures that allow us to comply with commitments made to the European Union by 2020 consisting in cutting emissions of carbon dioxide (CO2) by 20%, improving energy efficiency in another 20% and 20% of the energy consumed comes from renewable sources. To achieve these objectives Spain must make a great effort working on the development of technologies, products and efficient services in the fields with the greatest potential for energy savings, fostering responsible habits, which make it possible to lower energy consumption, improving the competitiveness of companies and the quality of personal life. The main consuming sectors of energy and where you can perform and promote energy saving and efficiency measures are: transportation, the more consumer of energy sector in Spain, moving closer to the 40% of the national total and especially the car that represents approximately 15% of the total, should strengthen measures such as labelling to promote low consumption vehicles and electrical, promoting alternatives to the private car as public transport, non-motorized transport and diversification in the mobility of people and goods, mainly in the transport by road buildingswhich represent 20% of the energy needs of Spain and where reductions of a third part of the consumption stimulating measures to improve the design of buildings and encourage the installation of more efficient lighting, heating, air-conditioning and hot water systems can be achieved.
This affirmation finds sentry box in the diverse segments of the society, except, ‘ ‘ classroom gestora’ ‘ that, what seems does not demonstrate sensitivity of ‘ ahead; ‘ caos’ ‘ that (DES) it involves the society and it affects, over all, poor than throughout the process of construction of the Brazilian society they had been kept out of society due to ‘ ‘ natureza’ ‘ in the way of capitalist production ‘ ‘ cultivado’ ‘ , this of the guideline of intention of the State abusively expropriated great part of the population absenting. The Brazilian poor classroom meets in this beginning of century XXI, therefore, unprovided of resources enough to supply its immediate necessities as: feeding, education, health and leisure having as alternative, the contemplamento with the politics ‘ ‘ paternalistas’ ‘ adopted for the State. The objective conditions of precarious works when existing they are generally e, insufficient, to understand one demand each more increasing time of the population city dweller what it contributes for the accumulation of the urban marginality. The populations of the cities (great, average and small) in turn, search alternatives for survival in the inferior circuit of the economy. The increasing marginalizao of the young generally leads these (poor) to the meeting of crime being coerced by the violent action imposed by the drug trafficking, and, infanto-youthful prostitution, fact that discloses to the abandonment and the state more declining than the human being are submitted when vitimado for a society that if it inspires in the expropriation as convivncia norm. In the poor peripheries of the cities, the young ones generally are launched in the conditions of search for the survival. They are improper conditions, therefore the search for the bread substitutes the search for knowing and the STATE, alleges not to make use of resources enough to invest in supramentioned strategical sectors already, which not being prioritized, testify of the intention of the State despot to support the people in a condition of perpetually subordinate life.
According to Coelho and Namba after the insertion of the PICC, could be noticed a discrete signal of bleed in the place where the puno was carried through, had to this it is used a o dressing with transparent film and gauze. This dressing will have in accordance with to be changed the protocol of the institution, or to any signal of integrity harmed of the covering. This transparent film makes possible very that the nursing team folloies and evaluates the aspect of the puno, being recommended had the protection that it provides in the place of insertion of the device.
This film is after indicated the insertion and during the maintenance of the dressing. The maintenance of the PICC demands an adequate manuscript of the nursing team and requires the use of an ideal dressing. This dressing will have to promote greater permanence of the catheter during all the therapy, therefore the inadequate stabilization can take the loss of the device. In virtue to be the dynamic of the overloaded UTIN of interventions, the nursing team, for being the main responsible professionals for taking care of, they must not only act in the direction of participar of the plan of cares, but also, executing and to evaluate its knowledge and its techniques in search of better resulted in regards to acquisition and maintenance of a venoso access in the RNPT. The study it extremely demonstrated the important paper of the nursing team in what one mentions the practical ones and interventions with technician-scientific conhecimento, during a implantation and maintenance of device PICC in neonatos interned in the UTIN. The PICC is a safe and very favorable device, mainly in specialties as intensive therapy in neonatologia, where the venoso access of the neonatos extremely is limited difficult.
The responsible professional for its insertion, either it nurse or doctor, must be apt to recognize the risks and the complications during this procedure, as well as the treatment related to the intercorrncias. The maintenance of the device requires the attention of the professionals, due to significant incidence of adverse events and complications that will be able to happen of inadequate cares. It is of extreme importance the qualification and permanent education of all the team of nursing how much to the manuscript of the device, promoting strategies that they aim at to characterize the assistance, with consequent reduction of the precipitated removal of the catheter and the complications related to its use, thus certifing, the security guard of just been born. A comparison between the intrauterine environment and the UTIN to evaluate the complexity of the problems faced for the RNPT is necessria. The nursing team must be intent and apt to intervine whenever it has some alteration during the use of the PICC. In this manner, the team must be zealous in regards to the interventions and humanizao of the cares to the neonatos. 1.
