Nanoscience science the studys the infinitesimal world, which is the world of atoms and
molecules. The agricultural field faces many challenges, including climate change, the increase
in the consumption of agricultural products and the reducing of the cultivated area, which
requires the need to advance agricultural development to achieve economic and agricultural
stability. Hence the importance of using nanotechnology and technology, which enables the
development of modern methods in the possibility of finding and treating many agricultural
problems. This is in addition to some of the main challenges related to the field of agriculture,
including the low productive efficiency in the cultivated area, the large size of the uncultivated
area, the loss of resources, including water, fertilizers and pesticides, and the loss of products.
This is in addition to the food security of the developing population, which can be faced through
the various applications of nanotechnology. Nanotechnology achieves remarkable achievement
rates in community service and environmental development. Yellow corn production is
considered one of the most important grain crops in Iraq to confront the basic needs of humans
and animals.

The new generalized operator F????,????
Univalent Harmonic Functions.We derived some properties by this conjunction like, coefficient
inequality, convex set, apply Bernardi operator and determine the extreme points such that
∑ ∞ ????=1 (???????? +???????? ) = 1,(???????? ≥ 0 ,???????? ≥ 0). In particular, the extreme points of ???????????? ∗
(????, ????,????;????,????) are {ℎ????} and {????????}.

A total of Forty isolates of Acinetobacter baumannii was Collected from many Hospitals
(Teaching Baghdad Hospital, Teaching Pediatric Hospital, Al-Shahid Kazy Al-Harery and
teaching clinical laboratories, Al-Yarmok hospital and Al- Kadhimia hospital) in Baghdad at
the period 15/11/2018 to 19/2/2019, including sputum 15 isolates (37.5%), Blood 14 isolates
(53%), wound swab 4 isolates (15%), Urine 4 isolates (10%), Burns one isolate (2.5%),
pleural effusion fluids one isolate (2.5%) and throat swab one isolate (2.5%) .
The current study showed that six isolates of A. baumannii that were resistant to colistin
(polymyxin) carry the (pmrA) gene at product size was 175bp. The gene expression of the
pmr A gene for bacteria was measured once it was treated with a Colistin (polymyxin)
antibiotic at a concentration (<=0.5µl) of 0.48 ml and without treated by using MIC
(minimum inhibitory concentration) method as it was measured. It was observed that there
was no increase in the gene expression of pmrA gene after the bacterial isolate was treated
with Colistin (polymyxin).

Chebyshev polynomial has wide applications in applied Mathematics. The Three Pass
Protocol is a cryptographic protocol that is used for the encryption and decryption of data
without the need to exchange the keys. We propose in this paper a new cryptosystem based on
applying the Chebyshev polynomial to the Three Pass Protocol. The proposed cryptosystem is
structured as asymmetric encryption that provides a high level of security to transmit the data.
This cryptosystem depends on the fact that the Chebyshev polynomial forms a semigroup
based on the composition property. The features of the proposed cryptosystem that are
provided by the Chebyshev polynomial are similar to the features that are provided by the
Discrete Logarithm. That is, it is secure from attacks, and it is faster to do mathematical
calculations. Therefore, the proposed cryptosystem is reliable, secure and faster compared to
the other cryptosystems.

The growth and characterization of iron oxide thin films by spray pyrolysis method using iron
chloride hexahydrate. Iron oxide films deposited on well cleaned glass substrate at different
substrate temperatures varying from 2500C to 5000C in air atmosphere. The characterization of
iron oxides films was investigated for their optical and morphological properties by using
spectroscopy and Scanning Electron Microscopy. The atomic absorption spectroscopy showed
the existence of direct band gap energy nearly 2.18 eV with varying substrate temperature.
Optical, structural and morphological observations were showed the film quality was getting
better at 350 0C substrate temperature, also grain sizes were cleared.

Food poisoning is the disease of toxic or infectious nature resulting or suspected to be resulting
from consumption of water or food. There are significantly underestimated cases of foodborne
diseases, and relatively few well-investigated outbreaks are revealed, though these often give
information on etiological agents and the reason behind contaminations. This retrospective case
study of collective food poisoning was designed to the establishment of a database inherent to
food poisoning specific for Diyala province / Iraq during the period between 2013-2021. The
results show that, between 2013-2021, 5 outbreaks of food poisoning were observed in Diyala
province involving 1188 cases (327 hospitalized & 0 deaths). The data in the study will give
information on the present situation and epidemiological evolution during the period of the
study. Female predominance was shown among the samples included in the study (Sex ratio
M/F = 0.85), and (54% of cases were female, and 46% of cases were male), and the age groups
which 68% were under 30 years old.62.8% of cases with water contaminated consumption, and
62.8% of cases in Baqubah2 sector. stool culture reports showed growth of different
microorganism.

Using the effect of computer simulation linear programming models with many objectives in
operations research. The maximum profits were calculated for companies in the ministry of
Industry in Iraq accurate. The Dual Model method was used for the conflicting objectives of
the model. This is done by using the corresponding model and then finding the optimal solution
for each objective function, which represents the profits and under the same restrictions. Then
extracting the average of the optimal solution for the multiple objective functions. And by
building a linear model with one objective that achieves maximizing profits for the factory.
Also we used modern computer simulation using WIN QSB programs to built according in
Steps to solving a multi-objective model.
