Spanish and Scottish researchers have added wool fibers to clay material that manufactured bricks and have joined them with alginate, a natural polymer that is extracted from algae. The result are a few bricks more resistant and ecological objective was elaborate brick reinforced with wool, and obtain a more sustainable, non-toxic compound that use abundant local materials, and improve its mechanical resistance. According to the mechanical tests performed, the compound is 37% more resistant than other stabilized earth bricks, uncooked. Advantages of the ecological brick researchers have analyzed the effect of reinforcement with wool sheep in different soils and have detected fibers to improve the compressive strength of bricks, minimize the cracks and deformations for shrinkage, reduces drying time, and increasing resistance to the flexion stress. This research is one of the initiatives that foster the development of more sustainable construction materials.

Included inside of the manufacture of bricks that do not require cooking, so it contributes to energy saving. According to the authors: is an alternative more sustainable and healthier than the masonry conventional materials, such as the baked clay and concrete blocks. The Earth without trying was one of first building materials used by mankind. The oldest examples are found in homes near east of between 11,000 and 12,000 years ago. In archaeological remains of the 14th century BC, located in Sardinia (Italy), also found earthy material mixed with plants or pebbles, resistant purposes.

Eng. Mario Holguin No doubt that road safety should be a basic item on the agendas of Governments. There are reasons more than enough to be considered as such by the ravages that cause violence in the streets and roads in organized societies. The indicators that we scarcely process in the Dominican Republic are insufficient, with the quality and quantity of the required information, which translates into an institutional weakness which we must overcome. However, the global and regional analyses reveal the high risk that exists in the transit and ground transportation for the survival of the road users and the economies of the Nations. While human factors constitute major risks, according to the statistics, not least is true that should be review and work also in regards to the road infrastructure, environment and with regard to motor vehicles. The fact of identifying many critical points in our road network is a determinant indicator to put through special attention security audits.

But likewise, courageous decisions should be taken to regulate conditions for vehicles, which is the second leading cause of risk in transit incidents. Near two thousand fatal victims are recorded annually in the national territory, and round in equal amounts the injured by the same cause. We do not have a mechanism to assess the conditions in which are the affected environment of those victims or follow-up to those affected by injuries before 30 days, resulting in the institutionally weak country. The lack of an Observatory of data, a strategic road safety, even more dangerous comprehensive plan, the non-existence of a leading institution in the sector that run these plans, evidence the State of unconsciousness of our society. We speak in these terms, because preserving the life of citizens, their health and their property is a prerogative of the human rights, but also, to ensure the free transit of persons, their education and social equity referred to in the achievements of civilization.

Thousands of families impoverished by transit incidents. Greenhouses gases and noises out of proportion by the improper circulation of vehicles involved in quality of life adversely. If we look at the huge losses caused by the many factors that require the implementation of a good strategic plan, we would give us account of the enormous advantages of savings in the national budget. The annual cost of the national road insecurity estimated that it represents around 15% of the budget and public spending bill today. Per 9 inhabitants in Dominican Republic there is a motorcycle, which transits without respecting rules or regulations. What brings as a consequence about 70% of the fatalities on the tracks. From the global point of view of our vehicle field, there is a motor vehicle per 4 inhabitants. But crucially, elders involved in accidents are users of motorcycles and pedestrians. There is not a driver’s education policy. Nor, controlling the growth of the Park motorized two-Wheeler. Without glimpse solution so far, where we walk with such a growing accident rate?

Nothing less than that. The component more harmful in that box, are the emissions of carbon dioxide, generated by internal combustion engines. In the meetings of the Group of eight, quantified the problem in 600 million motor vehicles. We acotemos in the Argentina circulating around eight (8) million of them. Our discourse is dilated and recurrent in the sense of the harmful effects that causes the automotive complex and its derivatives in the Argentine encounter. To more pollution, and waste and fuels, accidents caused by car accidents than this weighted by the insurance industry, is added in around 1.75 % of Argentine gross product. In the current year will be met half a century in which President Frondizi, signed the decree that approved of an automotive production regime, viewed at the time as a tool for development, with the passage of time step have a counter-productive effect by its negative aftermath. This decree that complemented the Nacional de Vialidad law of 1932 and which would be reinforced by the Larkin Plan, commissioned by the same administration that signed the Decree, which was intended not to complement to the system of transport that pivoteaba on the existing rail network and river maritime cabotage transport, but to replace it.

That substitution was traumatic and being very visible costs, still it is not weighted their projections. Learn more about this with Gavin Baker. For not to dwell on considerations, which we have done in previous communications (many of them available on the network), we want to emphasize the possibilities that opens the philosophy that supports this Law 26.473. We are aware that we border on the temerity when we promote the accelerated minimization of the extent of motor vehicles that are currently circulating in Argentina. It is still taken as positive aspects that are pavimenten roads, build new highways and increase the production of motor vehicles.
