Thus, while the concentration of population in Argentina, has its peculiarities both geographically and socio-cultural type, are analyzed in light of current thinking in the mid-eighties identified as a problem to the “poverty of metropolitan areas in the Third World” . In this tag, is framed not only in the Metropolitan Area of Buenos Aires, but Argentine metropolis below. What was not said in that assessment, or school for the Argentine case is the coexistence of the concentration of poverty with the concentration of wealth. Situation in the sixties was seen as the “typical dualism of underdevelopment.” While there are elements of theoretical and foreign cases to rescue the time of devolution, we believe that there are distinctive for Argentina. It is not the same concentration of poverty in a metropolitan area in a country with few natural resource endowments and small size, that poverty in metropolitan Argentina context of high availability of natural resources and plenty of land available for human habitat and productive activities. A later stop account of the coexistence of conflicting attitudes and decentralized concentrating on the specificity of the Argentine case, we hold that decentralize demographically refocus Argentina should not mean that is concentrated in the metropolitan area of Buenos Aires, in other major urban centers much less in the Greater Rosario, Cordoba Grand, Grand, or Grand Tucuman Mendoza.

Decentralize demographically in Argentina in 2005 means tend to make it as balanced as possible the existing human geography and location of available natural resources. A reference document illuminating of these potentialities, was known as a result of the parliamentary debate held in 1987 aimed at moving the Federal District. At the request of a U.S. Senator, ecological zoning was published by the National Institute of Agricultural Technology, and the one shown in according to a set of parameters which are the areas with larger and less availability of receiving human population and generate productive activities. It is remarkable in these times where it passes through the field of academic transdisciplinarity, returning from the compartmentalization of knowledge had led to the exacerbation of the “mathematically formalized experimental science”, as may be verified at this stage people from their compartments almost watertight, were devoted to study similar and sometimes almost identical problems or issues.

A comparison of the various technologies proper illumination, as well as the avoidance of shadow, contribute to a non-hazardous driving, inefficient (and also yellow) light due to rapid exhaustion and the error rate to rise. Here reveal the pros and cons of Worklight to buying currently on the market, and clearly explains the technical background. Halogen work lights the cheap halogen technology is common usage and classic for decades for Worklights. The principle is similar to a light bulb. A filament made of tungsten in a glass bulb positioned, with power applied and brought to light. The more favorable efficiency compared to an incandescent lamp is realized when a halogen Worklight this, that in the glass bulb no vacuum is but a halogen gas. The input electric power is converted to about 5-10% in broadcast light, heat approximately 90-95%. The color temperature of the Worklight (is used with the (“Unit Kelvin” quantified) is relatively low, the produced radiation is approximately 3000 Kelvin and is yellowish.

Pluses: Inexpensive minus points: Leuchtschwach (approximately approximately lumens/W) low durability (500 h) vulnerable to vibration yellow light Xenon headlamp Xenon headlights (also “HID-headlight” called) there since the early of 1990s, more often in the agricultural sector work headlights be used as they since about 2000. In a glass bulb filled with Xenon gas is an arc of light between two electrodes by DC (material: Tungsten) produced. With the Xenon gas mixed metal salts resulting in a high colour temperature of produced light (approximately 4500-5000 Kelvin, “Neutral white”). A high-voltage pulse of up to 25,000 volts is necessary to start (“burn”). For this a – often in the Worklight built-in – ballast is required, which also the light output of the work spotlight during the Use controls. Pros: Decent long-range illumination respectable light (approximately 75-85 lumens/W) yield minus points: extremely high ignition voltage (danger of Braising fires) full light output at the earliest 16-20 seconds after you turn on considerable dimensions by-LED work lights LED lights were used from 2004 in series car headlights ballast limited shelf life (2000 h), in the projects, you will find area increasingly used as Worklights.

A LED (light emitting diode) light creates a pressurized power semiconductor element. This sits on one of two electrodes in a glass flask and is associated with the second electrode by means of one or more “bonding wires” called strands together. The efficiency is relatively high, it is only insignificantly radiated heat. The light similar to daylight (Daylight White”or cool white”, approximately 6000 Kelvin), which the vehicle driver fatigue. There are often several LEDs in a working light installed. Durability (35,000 h) very bright light advantages: Superior respectable light yield (about 80 lumens/W) neither the durability due to constant on and turn off shock – and Vibrationsbestandig maintenance-free variety (Watts values, illuminated area) minus points: individual LEDs can be replaced keinstenfalls failure, means a LED work lights lights summary then merely as 15 instead of 16 light emitting diodes: LED technology is an increasingly important issue in the agriculture and forestry, current LED work lights are technically advanced and technically the price affordable and countless farmers given their superiority. The demonstrable benefits outweigh significantly, the investment costs have lowered on an economic level. Thomas Kampl

One another aspect important to detach is that new chances of study had been servants, mainly from the decade of 1990; scholarships and financings had facilitated the access to the university. The not motivated young population for the frustration of its parents with agriculture, started to look a new profession, thus leaving its locality in order to study and if to specialize in definitive chosen area. This time that the young leaves its house to study, instead of being temporary, generally becomes permanent, therefore it starts to establish new bonds in other places. Moreover, the leisure options, the new friendships, namoro, the search for one better job make with that this does not come back to its city, still more when evidence that its place of origin does not present expectations of growth and development. Of this form, the locality starts to serve only for familiar visits and vacation of work, becoming the scene emptiest with this ' ' gone without volta' ' of the student.

Who remains is some families who still have certain income and pensioners. We notice in to this influences it aspect that the globalization exerts in all the places for minors who are, the search for one better condition of life and the chance of access to the technology and all its benefits start to be essential, no matter how hard it is in all place, its bigger diffusion are in the cities where the population has greater concentration, it is plus aspect that becomes agricultural the disfavored one, although the cellular Internet and to be connected the houses of the community, it cannot offer more than what this, since they do not possess population nor production sufficient, for attracting its old inhabitants in return. The closing of the rank of health (figura9) and of school (development symbols), certifies the retrocession of the quarter, a time that the conquests had been lost.

More and more people who complain a lot to work with the computer about physical discomfort. These come in addition to the known back problems through the many seats, more and more problems in the area of the wrist, forearm and shoulder on. By posture and repetitive movements with a computer mouse may result in a but leave some of the joints and muscles. This can also affect back problems. For people with such problems could have a tablet help. Tests have shown that individuals with such complaints, the result of the use of a mouse, could be exempted from the use of a graphics tablet with pen operation of their suffering. The operation with a pen allows a much more natural position and movement of the arm.

How do you paint with a brush is a much more balanced load generated and used the entire range of motion of the arm. Besides the ergonomic handling a graphics tablet offers other advantages. It allows a much more precise work, which in particular the Imaging is a crucial advantage. Also offers a pressure-sensitive drawing tablet control. In contrast to a computer mouse, the mouse buttons only the state “active” and not “actively” know, a pressure sensitive graphics tablet works.

So you can for example, vary with a “brush tool, the thickness or opacity by varying degrees of pressure on the tablet. In addition to the pen included by default, there is another tablet accessories. So one can replace the standard required by a Airbrush pen stylus. Anyone who has worked with a graphics tablet know the advantages and resources in the future will use his mouse only rarely.

HSDPA + the new standard Internet access mobile operators such as T-Mobile, Vodafone, O2 are planning in the near future the expansion of HSDPA network to customers provide even more server speed. Although the current UMTS yet no coverage with the maximum speed network, theoretically 14,400 Mbit / s are possible, is thinking about a new technology. With HSDPA + speeds are planned, are level on high DSL. According to mobile operators, a download speed of 42 Mbit / s is possible. That would mean that even large files via UMTS in the extension HSDPA + could be downloaded within a very short time from the Internet. More multiple-antenna transmission is intended for this expansion.

This technique is already used range very successfully in the Wi-Fi. Another big advantage is that the UMTS licensees must perform no further expansion of its infrastructure. Should be for HSDPA + sufficient customers be found, mobile operators are quite fast with the conversion or Begin the extension of mobile Internet access. With long-term evolution (LTE) networks, there is still a further candidate for mobile Internet access, which is to reach even 100 Mbit/s. Also here faster latency can be realized. For LTE, but large investments in infrastructure are to make. If it is possible the mobile operators here to calculate prices which are similar to a DSL connection, and no longer to limit the UMTS flatrates, 5 GB per payroll period HSDPA + could evolve as a new standard for Internet access. It is however anticipated that this will take years. Peter Lindner
