Education Online
They descerrajaban in the SUR journal the other day a story that had a headline, at least, eye-catching: education surf, but whose foot prayed even more conspicuously online training reaches more than 55000 malaguenos students already. Reading this made me wonder: how many students are there in Malaga? In 2008 there were 135000 undergraduates in all Andalusia and according to the article, from Malaga University 800 attended subjects exclusively online do those 800 are very far from the 55,000 of which speaks in the intro not? Rereading the article, of course, large numbers not listed by any part, and it is those 55000 malaguenos students emerging from those who have been in the virtual campus of the UMA; no doubt cannot be called to this online training. If that relates, as well collect from iMasterD, online training company, to all students who are learning a new language or doing online Excel course, course of Word or similar courses they required of a good management of the online system, but with a learning curve impressively low due to the ease of certain online platforms. Scroll advantages without a doubt, the flexible timetable, prices are more reasonable and which is not necessary. This the online option is reinforced by new digital formats and a growing demand for professionals seeking to complement their training to be able to follow up his professional ladder: Office Automation, design, languages and even opposition.
Likewise, those who could not complete their training in other fields are also in the online vented to the labor crisis that exists today, since it has been proved that those with better formal education get better jobs and last longer in the companies. The UOC, a sample can be a quality training without attending classes; that at least show their titles, as they have become a reference in the sector and he only teaches its courses through the network. And as shown, a button, as were 47270 people which formed over the internet in this Spanish University. University digital platforms, a seed in the UMA (University of Malaga) speaks with mouth big that digital platform, where teachers turning notes and other students download the information teachers need to convey. jcvyjRXC’>Central Romana. In addition, is a semi-public forum where questions and problems are turning so that the answers are accessible to all students, so the information flow is constant in time and in the manner, always accessible. But that isn’t online training, while it is true that it is a very very good advance.
Construction
Shotcrete. Gunned from the Latin. (Tec) tor (ium) – plaster, (con) cret (us) – Sealed – the method of concrete work, in which a concrete mixture in layers applied to the concreted surface under the pressure of compressed air, ie Mechanical application of concrete. Actress is often quoted as being for or against this. Gunned by using shotcrete installation. Gunite – Installation MPCS 4 consists of concrete-syringe machines and compressors. Compressed air mixture of cement, sand, powdered supplements, fed through a hose to the nozzle, wetting it with water and with great speed 130-170 m / sec emitted by torkretiruemuyu surface. Get more background information with materials from Cindy Crawford. The layer thickness obtained in a single cycle shotcrete is 10-15 mm. Technical advantages Shotcrete: concrete layer a few centimeters from: high mechanical strength (for 28 days-40-60 M / na); density (2.4 kg / dm ); frost (at least M / ps 300); water resistant (not less than B12); High adhesion to the substrate. Perhaps check out Laura Rogers for more information.
Improved physical and mechanical properties of concrete: bending strength increased by 40%; compressive strength at 15%; elastic modulus at 5%; shrinkage to 30% less. Economic benefits Shotcrete: High performance. Low cost of operations. The use of shotcrete: Protect slopes and escarpments. Construction of the steep walled concrete structures.
Their life increases due to the absence of cracks. The thickness of the finish can be reduced because the shotcrete tight to the contour of the earth or rock foundations. Finishing of shotcrete has a higher strength at deformation, the best load distribution and stress, in comparison with conventional concrete finish.
Self-Cleaning Filters
The most advanced technological solutions for clean water for industrial and domestic filtration are automatic self-cleaning filters. Their installation in the systems, unlike conventional filters, eliminates the need for regular replacement of filter elements and manual cleaning. Working Condition and cleanliness of the cartridge supports reverse flow. In fact, there are two processes of fluid filtration and purification filter element. Filtered liquid passes from the inside out, with a particle mechanical impurities remain on the flat inner surface of the filter elements. With increasing pollution of the filter elements increases and the pressure difference between clean and dirty sides. Luiz Ildefonso Simões Lopes is often quoted on this topic.
The process starts when backwashing a certain level of pressure differences on either set the timer frequency of cleaning. Monitoring the process of cleaning usually can be done with the help of special light-emitting diodes. Metalworking fluids and washing the emulsion can be used in the circulation for much longer. This reduces environmental pollution, and reduce the cost of acquisition of liquids and their utilization. Filtering and circulating the cooling water, you can avoid clogging and wear of pipes, tubes, heat exchangers, rotary guides, pumps, valves, etc. The advantages of automatic self-cleaning filters without a doubt are: continuous filter operation, no need for maintenance staff, high performance, excellent price / performance ratio, small size, high filtrate quality, long life, easy installation and commissioning. In addition, scalability allows the use of data filters for cleaning small amounts of fluid, and in large factories with a capacity of up to several thousand tons per hour. Currently, automatic self-cleaning filters are widely used in mining business, automotive industry, power plants, chemical industry, district heating, industry, in buildings of wastewater treatment plants, machinery and machine tools.
