Abstract: The Fibonacci sequence is a famous equation, because
it's have amazing and great properties. In this study, we prove some
of the interesting properties which include the relations between
Fibonacci numbers and (9, 19, 29). We found a lot of connections
and relations between them.
I INTRODUCTION
The Fibonacci sequence was given its name in May of 1876
by the outstanding French mathematician Francois Edouard
Anatole Lucas, who had originally called it “the series of
Lame,” after the French mathematician Gabriel Lame [1-3]
the applications of both Golden Section, and Fibonacci series
takes a lot of interest in modernistic science, like biology,
demography or economy, and recently used in high-energy
physics, but there exist generalizations of these numbers given
The Fibonacci sequence Fn are
1, 1, 2, 3, 5, 8, 13... 144, 233, 377, . . .
Each number in Fibonacci sequence (as in previous equation)
equals to the sum of the next two Fibonacci numbers. If n is
any positive integer, so Fn is what we use to explain the nth
Fibonacci number, then
Fn = Fn −1 + Fn −2
Because of this sequence Ref. [11] starts with the values:
F0 = 0, and F1 = 1

On the other hand the ratio of two consecutive Fibonacci
numbers converges to the Golden Mean or Golden Section [
12-15] sin (2_/5)/ sin (_/5) = 1.618.
Figure (1) shows some of the natural phenomena of the energy
giant, which is one of successive applications Fibonacci.

The summation of the first (19) numbers in the Fibonacci
sequence is divisible by the number (19):
(0 + 1 + 1 + 2 + 3 + 5 + 8 + 13 + 21 + 34 + 55 + ... + 2584) =
6764
6764 / 19 = 356
The resulting number is (6764), which is a unique feature. It is
equal to: 19 x 4 x 89 = 76 x 89
This number (89) is the number of Fibonacci His status (11)!
It reversed the wonder that is equal to: 1/89 = 0.01123595 ...

itself reverse this process and our destination because we
reverse the first (19) a number in the Fibonacci sequence, so
that it becomes the first to be the last and the last is first, here's

As shown from the Table 2 part 2, if we add no. (1) of the
Fibonacci sequence to the offset by in the inverse sequence,
the came out number is divisible by (19) . Also if this number
rose from the number (2) of corresponding Fibonacci
sequence also the came out number is divisible by (19). Then,
if we add to the third issue in the corresponding successive
reverse, once again came out number is divisible by (19) ...
and so on until we reach the Fibonacci number (19)! It
calculations alternately: time to add and subtract time, which
is never left behind, and achieved only with the number (19)
[23-31]. Also, if the process has all the numbers that follow
ranked number holder (19), found that the calculation between
each number in the Fibonacci sequence and the corresponding
sequence in reverse, the process is always put:

Look at how successive changed body and set aside, to be
the location of number (19) directory location, and to suggest
various images that the subject of this number (19) of which is
destined recognition aesthetically surprising!
The aim of this study is to show the relation between
Fibonacci sequence and (9, 19, and 29) numbers, and to prove
that if the plants are a families, the animals and the entire
component in our world as well as the numbers are families.
This work is a part of continuous efforts in the Energy and
Renewable Energies Technology Center to study the nature
and find the best energy motivation for our live [32-55].

II RESULTS AND DISCUSSION
1. If the first number is divided on the Fibonacci (19) is the
owner of status (19), followed by the number that this
feature is the number of Fibonacci His status (37), which is
between him and the first (19) status exactly? Then the
next is the owner of status (55), which is also the second
(19) status.
2. The sum of the preparation for the first nine successive
preparation of any number from zero to 21 is the number
54 and this number is divisible by 9, and without rest,
54 ÷ 9 = 6
3. The sum of the preparation for the first 18 consecutive
number from zero to the number 1597 is the number 4810
and this number is divisible by 19: 4810 ÷ 19 = 220
The number 18, which refers to the first number is 18 (9 *
2) It is here shown that there is a relationship between the
number 9 and number 19.
4. The number 19 is the same in successive number is
2584divisible by 19: 2584 ÷ 19 = 136
5. The number 29 is the same in successive number is
2584divisible by 29: 317811 ÷ 29 = 10959
6. The total number of successive 29 for the first number
from zero to number 317 811 is a number 832 039 and that
number is divisible by 29,
832039 ÷ 29 = 28691
7. Total prepare for the first 36 consecutive any number from
zero to number 9,227,465 is the number 24,157,816 and
this number is divisible by 19,
24157816 ÷ 19 = 1271464
And the number 36, which refers to the first number is 36
(9 * 4) and this again shows the relationship between the
number 9 and number 19.
Since there is a relationship between the number 18, which
is twice the number 9 and number 19, now we have to
prove a relationship between the
Number 19 and the next in the series after the 18 number
that is 18 +19 = 37,
A number 14,930,352 and this number divisible by on 19
without rest: 14930352 ÷ 19 = 785808.
8. There is also a relationship between the number 37 and the
next in the series after a number 18 or 18 +37 = 55, a
number 86,267,571,272 and this number divisible by on
without the rest of the 19:
86267571272 ÷ 19 = 4540398488
9. It is known that the sum of the numbers 9 +19 +29 = 57
and this number is divisible by 19 without the rest of the
57 ÷ 19 = 3. Now if we take the corresponding numbers in
the sequence of the No. 9 and the two numbers 19 and 29,
a 21 and 2584 and 317 811 does wonder if the sum of
these numbers are accepted multiple of 19 as the
corresponding numbers
21 +2584 + 317811 = 320416 and 320416 ÷ 19 = 16864
To see consistency between successive sequence and
corresponding of how to prepare in harmony with the number
19 in tune bizarre.
10. The sum of the first 19, the result is divisible
(136-84 + 52-32 + 20-12 + 8-4 +4 +0 +4 +4 +8 +12
+20 +32 +52 +84 +136 = 836)
The number 836 is divisible by 19
836 ÷19 = 44
11. When you multiply the following numbers among them
9 * 19 * 29 = 4959
And when collecting the numbers of the last one:
4+9+5+9=27 the number is divisible by 9
27 ÷9=3
And the last divided by the number 19 produces the
following: 4959 ÷ 19 = 261
Also, if we collecting the last numbers we will get:
1 +6 +2 = 9
III CONCLUSION
In this research we found and approved that there is a lot of
relations between the numbers 9, 19, 29, and Fibonacci
sequence and if we search more may be we will find more
than this.

At present, the numbers of transport vehicles on the road are increasing all around the globe despite its environmental pollution. The variety of vehicles on the road leads to emission of different types of greenhouse gasses and particulate matter. These severely affect the environment and significantly affect the concentration of pollutants in the atmosphere. In Oman, at the end of 2014 the number of new cars increased by 8.6%. In Sohar, which is in the Al-Batinah region, around 48882 per day vehicles pass through Al-Batinah highway in front of Sohar University. The OPSIS system installed by the Environmental Research Center at Sohar University monitors records the sulfur dioxide and ozone emission from these transport vehicles. The research study tries to establish a relation between the traffic volume and the air sulfur dioxide and ozone concentrations in and around the Al-Batinah highway near Sohar University. An attempt is also made out of that to generate awareness and investigate the resident willingness to reduce greenhouse gasses.

Natural gas and liquefied petroleum gas are the most important alternative fuels for gasoline in spark ignition engines, for many reasons, such as large world reserve of these gasses, high heating value, high octane number, low emissions emitted from burning them in engines, and their small prices compared with gasoline. The practical study conducted with these two fuels to operate single cylinder with variable compression ratio, speed and spark timing Ricardo E6/US, and its performance was compared with that resulted from running the engine with gasoline. The results appeared that the HUCR (higher useful compression ratio) for gasoline was 8:1, 10.5:1 for LPG and 13:1 for natural gas. Results appeared that spark timing was advanced when using NG more than other used fuels, because of its low flame speed propagation. The study conducted that brake power of LPG and NG were less than that for gasoline at CR=8:1, but they became closer when the engine operated at HUCR for each fuel. The results showed that specific fuel consumption for NG less than that for LPG, which was less than that for gasoline on a mass basis. Also, the exhaust gas temperature for NG was found to be less than LPG, and it was for LPG less than that for gasoline

The engine cold starting in cold weather causes high emitted rates of pollutions. In this study, a Mercedes engine was used to evaluate the impact of cold starting speed and time on the emitted emissions at winter days of Baghdad City-Iraq. The tests results indicated high emissions levels, especially of HC in this period. The carbon monoxide (CO) and carbon dioxide (CO2) concentrations depend on the injected fuel quantities and the ratio of the burning fuel. CO2 emissions increased at 1000 rpm compared to other speeds about 25.56 and 18.18% from 800 and 900 rpm, respectively. The unexpected result was the nitrogen oxides (NOx) concentrations, which were relatively high especially at 1000 rpm, with about 42.9 and 25.18% higher concentration at 800 and 900 rpm, respectively. The engine emitted high rates of lead (Pb). Compared to 1000 rpm, the engine emitted about 24.84% and 17.07% higher rates of Pb at 800 and 900 rpm, respectively. The engine noise reduced with increasing the starting speed partially.

Every day more research is made in the field of solar energy specifically in hybrid photovoltaic/thermal (PV/T) collectors, which is a combination of both solar technologies. Researchers have targeted this system configuration because it has an improved overall efficiency, with a comparison to both photovoltaic (PV) and solar collectors, and it saves space using one area for two systems instead of using two zones. The majority of researchers presented new models/designs while others provide studies on pre-existing ones for different environmental conditions. However, it is important to review their work to find key ideas to consider for future works and to capture the limitations of research in this field. This paper presents principles of PV/T collectors, classification, history of research, major aspects in PV/T research and critical review of the presented review literature, as well as the PV aspect of the system. More focus in this study is directed towards the electrical side, in particular, the PV part of the system.

The interest in energy conservation and management comes from the increased demand on energy in the present day. This issue has become necessary to achieve sustainable development of the society. Energy conservation means the change in the pattern of energy consumption and pursued to reduce the increasing growth in energy consumption. The case of rationalization of energy consumption needs clear mechanisms to address the problem of high consumption rates. Also, the attention should be paid to the transition to a sustainable energy sources that can save energy through natural sources rather than fossil fuels. The energy conservation enlightenment should be promoted among segments of society, whether individuals, families, institutions, and companies to ensure continuity for future generations. The goal of reducing energy consumption can be done in several ways, starting from the design of the building that gets use of the natural energy resources. The employment of thermal insulations at the outer wall is another type of energy conservation. Also, the replacement of bulbs with lamps that consume low power is one of methods of reducing energy consumption. In this paper, the focus was on electrical devices usually used in homes in Oman. Also, the number and types of the used lighting devices were measured, the energy consumed, the number of air conditioners, the number of working hours, and the monthly bill were followed up and recorded. We also conducted a questionnaire to measure the extent of people's knowledge of the importance of energy conservation and ways to preserve it.

Dust depositions on photovoltaic (PV) modules reduce the transmittance of PV glazing, resulting in the degradation of efficiency. The primary source of dust is wind-blown sand and soil particles from the ground. The coarse dust particles have a diameter larger than 2 μm. Photochemical reactions of gaseous pollutants in the atmosphere and dried droplets of seawater forming salt particles form most of the fine particles smaller than 2 μm in diameter. The physical properties of dust, such as specific gravity, particle shape, surface properties, moisture content, plastic and liquid limits, and particular grain size, vary from location to another all over the world. These differences are due to the topographic, geological, and environmental conditions of each region. The weight and shape of dust particles have a significant effect on their deposition behaviour and PV performance. In this paper, an investigation of energy losses caused by dust deposition on PV modules in Oman is presented. Six dust samples collected over three months from six locations in Northern Oman were investigated to evaluate their physical properties. Most of the dust particles (64%) diameters size ranged from 2 to 63 μm. The dust deposition on PV modules was found to vary from one location to another. The results indicated that there is no significant energy-yield loss caused by the low surface mass concentration of dust (<1 g/m2) on the PV module. The maximum daily efficiency loss was measured and compared with that from the literature, revealing that the efficiency loss was 0.05%, which is small compared to those of neighbouring countries. However, the results show a decline in the productivity of the PV module up to 35–40% after exposure to the weather conditions for more than three months, indicating that the advisable cleaning period, is every three months. Therefore, establishing PV systems at these sites is a reasonable option.
