[Font: Time New Roman 14, Spacing: single] Here you can give a detailed description for you experiment and procedures/ method or theory which used in your paper.
Equations (if any) should be presented on a separate line from the text with a blank space above and below. Equations should be clear and expressions used should be explained in the text. The equations should be numbered consecutively at the outer right margin, as shown in Eqs. (1) – (2) below. Here is one example.
In this case, the governing system of equations can be written as follows:

a+ b = g (1)
x+d = r (2)

Results and discussion (Font: Time New Roman 14 bold)
Here you will give the obtained results. The results and its dependent as well as manipulation will explain.
[Font: Time New Roman 14, Spacing: single.] Figure captions and table headings should be sufficient to explain the figure or table without needing to refer to the text. Figures and tables not cited in the text should not be presented.
Tables and figures should be placed close after their first reference in the text. All figures and tables should be numbered with Arabic numerals. Table headings should be above the tables.
Here is given example for figure and table:

References should be readily available publications.
List only one reference per reference number. If a reference is available from two sources, each should be listed as a separate reference.
The template will number citations consecutively within brackets [1]. The sentence punctuation follows the bracket [2]. Multiple references [3], [4] are each numbered with separate brackets [4]-[6]. Refer simply to the reference number, as in [7]—do not use “Ref. [7]” or “reference [7]” except at the beginning of a sentence: “Reference [7] was the first . . .”.
At least five references could be cited in your paper.
Here are three examples for references: [1] papers, [2] book and [3] website;

“ The main causes of air pollution are related to the ignition of fossil fuels (coal, oil and gas). The combustion of these raw materials occurs mainly during or in the operation of the industrial and land transport sectors. In the industrial sector, it is necessary to differentiate between factories (for example, cement or steel) and power plants (which produce half of the electricity consumed in our country).
The main causes of air pollution are related to the ignition of fossil fuels (coal, oil and gas). The combustion of these raw materials occurs mainly during or in the operation of the industrial and land transport sectors. In the industrial sector, it is necessary to differentiate between factories (for example, cement or steel) and power plants (which produce half of the electricity consumed in our country).
The division of responsibilities in air pollution between the industrial sector and land transport is clearly imbalanced towards transport. About 80% of air pollution in Spain is due to road traffic.
Modern societies have organized themselves in transport, as in other aspects, and against all the basic principles of Nature. As humanity has become surrounded by technologies, the means of transport have acquired a more mechanical character, trying to satisfy two basic tendencies, independently of the problems they may cause: on the one hand, increase of the speed and secondly allow a relative independence of the users. This surge in transportation technology has resulted in greater convenience and efficiency in service, but on the other hand, it is causing an intolerable increase in the environmental and social impacts associated with this activity, between other air pollution.
In Spain, transport uses almost 40% of the total energy consumed (the EU average is 30%), this figure increases to 50% if we consider the productive cycle of transport in its entirety. Taking into account the complete transport cycle, not only is the fuel used by vehicles to move (the energy cost offered by official statistics), but also the energy consumed in the manufacture of the vehicle, the construction road infrastructure, its maintenance and, ultimately, the destruction of the vehicle.
The road is today a means of transport and continues to gain ground against the railways, as long as it is necessary to attribute to the unbridled increase of the transport the development of the road transport. Road transport represents 90% of the various means of transport, compared to the train which remains at a small 5%. In road transport, the private car consumes half of the energy resources, while public transport only consumes 3%. The average occupancy index of private vehicles is 1.2 persons per car. In the city, half of the trips made by car are for distances less than 3 kilometers, and about 10% for trips of less than 500 meters.
The same thing happens with passenger traffic, but also with goods, which are mainly transported by road: on average 70% of the total transport in the EU countries, which goes up to 90% in Spain, which means that the train has gradually lost importance, abandoning lines and services, to represent today only 4.2% of this traffic. This rail decline coincided with a large increase in freight transport, which was multiplied by 3 as a consequence of the enlargement of the EU (with the entry of Spain and Portugal, among others) which causes serious congestion problems in the main European cities, congestion that is already occurring 100km from major cities.
On the other hand, the transport of goods by road to a significant environmental impact, which also continues to increase. Although trucks represent only 10% of vehicles, they emit between 30 and 40% of nitrogen oxides and suspended particles. They are also responsible for most of the sulfur dioxide emissions from road transport.
This predominant situation is not the result of a natural evolution of the economy, but it responds to transport policies that benefited the latter to the detriment of others through tax measures, subsidies and construction. infrastructure (year after year the road takes between 60 and 70% of major investments in transport), although it is the least efficient means of transport and creates environmental problems.
