The integration of renewable energy systems and the electrical power system has a great interest both in academia and industry. In recent years the main goal of all researchers has been to implement a smart grid that allows each house to meet its special needs of energy from renewable energy sources, such as solar or wind. As a result of the evolution of the control and surveillance systems that rely on the collection of data in real time and energy management and control of the renewable energy systems based on the performance of the telecommunication infrastructure, the process of providing energy from renewable energy sources for each home has become possible.
This paper focuses on the analysis and evaluation of performance of a control and surveillance network using both wired and wireless technologies (Ethernet, Wi-Fi, ZigBee) to monitor and control distributed Energy Systems, which include small wind turbines (WTs) photovoltaic systems (PV), through the definition of different types of wiring and instrument to monitor the status of renewable energy systems for homes and smart buildings using OPNET.

Vehicles while on the move request different information in VANET, by enabling communications between vehicle-to-vehicle (V2V), and vehicle-to-infrastructure (V2I) by using a pervasive deployment of vehicular networking technologies.
This would have an unprecedented impact on mass road transportation and on huge services for the VANETs applications.
In this article, a review study was made to find out the procedures which can be used to insure the transfer of information via VANET networks over high ways traveling vehicles and to clarify the challenges appear when information processed. Flowcharts were put for transferring requests and for applying queries especially when p2p is applied for connection between networks.
The article presented also a study of the protocols which are used for transfer queries between similar nodes by using different methods and techniques. Results and conclusion were put.

Current wireless sensor networks (WSNs) require effective network simulation methodologies and embedded software performance analysis because of the increasing complexity and low power constraints imposed on these networks, as well as the security feature they should have for using sensitive data in undesirable and hostile environments.
This article includes a methodology for security analysis in wireless sensor networks through the design of a built-in firewall or a set of countermeasures. This is done by modeling the attacker and simulating the attack with the performance analysis (node execution time and power consumption estimate taking into account the spread of the network components and the topology) after examining three different types of attacks that mimic most attacks on wsn, It is capable of designing hardware devices, software programs, and basic wireless channels.
The planned simulation provides developers with necessary information about the effects of a single attack or a series of multiple attacks on the network, helping them develop more secure wireless sensor systems, and the WSN attack simulator is an essential element of the built-in anti-malware development strategy Of the attack put forward in this research.
A methodology that allows the design of secure WSNs from the first steps of the development – Dr. Fidel Ibrahim
Some of the food is a source of energy and at the same time has a variety of satisfactory
medical prosperities, so it became necessary to search for these materials and conduct studies on
them. Perhaps honey and royal jelly are the most important nutrients and medical that have been
used since ancient times. They are considered as a cosmic miracle because they contain the
antioxidants that contribute to the prevention of the mutant effects caused by chemical drugs. So
it is very important to illustrate the ability of honey with royal jelly in mitigating or eliminating
the toxic side effects caused by the Adriamycin. the drug, which is one of the most popular
anticancer drugs. From these side effects are the alteration of the cellular and histological
structure in the ovary, the disturbances of the ovarian sexual hormones and the menstrual
disturbance that lead sometimes too early menopause and weakness in the reproductive capacity.
As a result of this research honey and royal jelly have a clear role in maintaining the vitality of
the ovary cells against the impact of these side effects. hence they contribute in maintaining the
hormonal balance and getting rid of hormonal disorder of the ovary and increasing significantly
the number of ovulation and the fertility rate, in addition to raising the embryonic safety rates and preventing them of death

The natural pharmacological products are considered now of the dependable products in
the treatment of many diseases under the name alterable medicine, due to its natural compounds
which are without side effects although of their ability to treat the side effects of the chemical
pharmacological products. One of the most important products is the Extract of the Ginseng
roots plant, which is considered one of the most herbal drugs, spread in the East of Asia, and
considered in 1990 inside the complementary foods, used in the treatment of infertility (atocia)
cases and the hormonal disturbances resulting from the menopause. Hence, the importance of
this study is to illustrate the profitability of this plant in the treatment of the negative side
effects of Adriamycin, which is considered one of the most used anti-cancer drugs, especially
its effect on the mature follicles and the corpus luteum that have the big effect on the activity
and the ovarian physiology, as a result of menstrual disturbances and infertility in women
who received this drug. This study showed the importance of the Ginseng roots in the
maintenance of the normal levels of ovarian hormones, despite the toxicity of this drug,
consequently the increase in number of ovulation stages, and the increase in the fertility level
about 23.5% , and the recompensation of the decrease that results of the toxic effect of ton the follicular cells

The chemical substances used in cancerous tumors treatments are considered to be one of
the cytotoxic oriented to the rapid division cells. Adriamycin is One of the most anti-cancer
drugs used in cancerous tumors treatment, particularly in breast cancer which spread increasingly
in Aleppo (2010 static). although this drug is the least cytotoxic comparison with other drugs, the
identification of its cytotoxicity and the histological side effects still need much work to do.
Accordingly, this study illustrates the negative impacts caused by the drug on the histological
structure of ovaries and especially the mature ovarian follicles, the most effective of which plays
a principal role in the activity of the ovary and the organization of the sex hormones. This study
has shown the effected of Adriamycin in the cell and histological stricture, and the activity of the
granulosa cells division in the ovary, the karyorrhexis of nuclei in granulosa cells, shrinkage of
cytoplasm and structure, reduction in the activity of its division, loss of its interactions, and some
alteration in the theca structure. These alterations have shown also in the structure of the egg in
the mature follicle, absence of nuclei and regression of both, the cellular membrane and the cytoplasm.

Adriamycin is one of the most anti-cancer drugs used in cancerous tumors treatment, and
at the same time, is the least cytotoxic.
However, the identification of toxicological and histological side effects of this drug still
needs much research works to go. Accordingly, this study illustrates the negative impacts
caused by the drug on both histological structures of ovaries and ovarian follicles.
This study has shown affected by cellular and tissue structure on the granulosa cells for
example; the karyorrhexis of nuclei in granulosa cells, and shrinkage cytoplasm structure has
lost its interactions, some alterations in the theca follicle structure, especially the shape of cells
and their nuclei which became fusiform. And from the changes in the features and structure ofthe egg in the level of each follicle. an absence of Oocytes nuclei and regression of the cellular
membrane and finally cytoplasm
Those changes have been accompanied by a gradual regression in both weights and sizes
of ovaries and bodies of all experimented animals directly after the drug has been injected until
the 10th day. But Some ameliorations have been observed in all studied groups after the 10th day of injection

Abstract: Adriamycin drug is used in the treatment of the cancer tumors, especially the
breast cancer, and because of its side effects on the sexual reproductive cells, this study came to
illustrate the possibility of preventing these side effects by the natural pharmacological products
as natural honey and royal jelly mixed with Ginseng roots. This study showed the contribution
of these natural compounds in maintaining the vitality of the ovary, the histological structure of
the mature vesicles (Graafian follicles), the Oocyte, so contributing in maintaining the
production of high-level ovarian hormones, and the ovarian cycle without disturbance, hence,
preventing the early menopause in females (sexual sterility). This study showed also an increase
in the ovulation stage compared to the group injected with the drugs without a protective dose.
