The transport fleet is one of the most basic daily needs of the people of cities. Of course, in addition to daily commutes, cities that are tourist destinations must also provide suitable means of transportation for tourists. Transportation management is all planning and executive activities aimed at optimizing transportation systems. Sustainable transportation means transportation in which transportation needs are well met and fair access for all people, their safety and environmental health are taken into account in planning for its present and future. Urban transportation problems: The most important urban transportation problems, especially in large cities, are: 1- Traffic that causes people to spend a lot of time when cars are stopped or moving. Rush hour (traffic peak) is the hours of the day when the presence of vehicles and pedestrians on the streets of the city reaches its peak.
2- Air pollution and increase in respiratory diseases, headaches, fatigue, stress and blood pressure, which are important problems of big cities.
3- Noise pollution and pollution caused by noise of cars, motorcycles and worn-out cars.
4- The problem of lack of parking and wasting time to park cars.
5- The cost of constructing highways and purchasing and repairing the urban public transport fleet
Municipal service machines are a set of devices that are built for the purpose of mechanization of service affairs of organs and organizations related to municipal services, especially municipalities. These devices, which are placed on the chassis of heavy vehicles, are known as municipal service devices or municipal service machines, which are divided into several groups depending on their function. Including: street sweeping machine, table washing machine, street washing machine, sludge washing machine, fire extinguishing machine, rolling arm machine, garbage transport machine, tank washing machine, ambulance and dead transport machine, dumping machine. As the name implies, these devices are used for the purpose of urban cleaning and performing services such as transporting the dead and emergency services. The design and construction of this type of device, due to the sensitivity of the subject and the very precise technical and engineering issues in the structure of this type of device, requires knowledge at excellent levels, as well as extensive work experience and the use of expert and experienced personnel.
Urban furniture is a wide range of tools, objects, devices, symbols, buildings, spaces and elements that are known because they are installed in the city and on the street and in general and are used for general purposes. The main role of urban furniture at the level of streets and urban spaces is to create places that speak the language of human identity and the desired urban landscape.
Studies conducted in recent years show that pollutants of particulate matter, especially particulate matter with a diameter of less than 2.5 microns, are the main cause of unhealthy air in Tehran. Meanwhile, mobile sources have a share of more than 80% in the production of this pollutant, which is the share of diesel vehicles more than 50% of the total pollution of particulate matter produced in Tehran.
Small Scale Generator is a set of power generation facilities that can be operated as a connection to the national grid. Provided that the practical production capacity at the time of connection to the network is not more than 25 MW.
Due to the fact that diesel generators available in factories or various other industries can not be connected to the national grid and the continuous production of electricity on an annual basis and are mostly used for standby purposes. Therefore, gas-fired permanent power generators can be operated 24 hours a day and also connected to the grid, and are in fact a good option for the use of small-scale power plants.
Due to the depletion of non-renewable energy sources, such as oil and gas, and the problems that the use of these energies has created, such as climate change, air pollution and environmental degradation, the use of renewable energy is essential. More than ever, our world is threatened by heavy dependence on fossil fuels, especially oil and coal. Air pollution, environmental degradation and climate change are the result of this dependence.
That is why the supply of energy from renewable sources is very important. Renewable energy sources are clean and do the least damage to the environment. At the same time, these resources are inexhaustible and will be usable for many years and generations to come.
Fintech stands for Financial Technology, which is the use of technology to make financial services more efficient. In other words, we use cellphones and computers to do our financial work more easily. The term fintech refers to companies that use technology to change the user experience of financial services and offer applications or products. In the past, large corporations did this and controlled the market. But the situation has changed after several years and now startups want to offer new services to users with a lot of hope and desire. In general, startups in this field try to connect individuals or companies to make transactions. Most FinTech users are small businesses who do not want to have to worry about paying for a lot of money. In this way, businesses are able to grow faster and spend their financial resources on marketing and other needs. In fact, this is one of the goals of FinTech.
The steel chain goes from the production cycle to the consumption of steel and steel products from the exploration and extraction of iron ore mines as the raw material of this cycle and the related field of extractive metallurgy to its conversion into concentrate, pellets, sponge iron, ingots and other products in factories. The producer of iron and steel and related industrial metallurgy, and at the end of the chain includes industries and consumer companies, including automobiles and construction, as well as intermediate industries as the bridge of the chain. In Iran, by using cheap energy and iron ore mines, optimization, development and completion of steel supply and production chain is a smoother way ahead, and even with these capacities, it can be one of the world's steel production powers.
The purpose of establishing this center is to attract top business ideas and start-ups in the field of development investment and urban industries in order to carry out charitable activities.
