Vibration, occurring in most machines, vehicles, structures, building and dynamic systems is undesirable, the reduction in performance which accompany vibrations and the dynamic stresses which may lead to fatigue and failure of the structure or machine. Vibration analysis of machines and structures is often a necessary prerequisite for controlling vibration. The vibrations of any dynamical system are needed to be controlled to minimize or eliminate the risk of damage or destruction. So many passive and active control techniques are used to eliminate or suppress the vibrations to minimum level. One of the important subjects expressed here is the dynamical systems, which are governed by different types of non-linear differential equations. The main object of this thesis is a mathematical and numerical study for the vibration behaviors in two different systems which are described by non-linear differential equations. The first system describe the active vibration control of a nonlinear two-degree-of-freedom system due to electromechanical system under external and parametric excitation. The second system study the nonlinear integral positive position feedback control of a cantilever beam system carrying an intermediate lumped mass by a three -degree-of-freedom with external excitation force. For each system, the investigation includes the analytical solutions applying the multiple scales perturbation technique (MSPT), determination of the resonance cases, which are classified into different categories. Some of resonance cases are confirmed numerically. The stability of each vibrating system and its steady state solutions are investigated by using both the frequency response equation and phase-plane technique. The numerical solutions are focused on both the effects of the different parameters and the behavior of the system at the selected resonance cases. Comparison between analytical and numerical solutions is obtained. Also all the numerical results are obtained using MAPLE and MATLAB algorisms. Some recommendations are given regarding the design of such system.

BACKGROUND: cadmium is among the toxic and hazardous metals widely dispersed in the environment at high levels; it is known to be toxic for the kidney. Tribulus terrestris L. (TT) plants in Saudi Arabia. It has been used as a protective herb for kidney disorders. The present research aims to study the possible ameliorative potential of T. terrestris extract on Cd- induced effects in human embryonic kidney (HEK 293) cell line. METHODS: we have studied the cell viability and IC₅₀ by using SRB. Then, cells were divided into six groups of triplicates treated for 12 h and 24 h as follows: group 1, normal (untreated) control; group 2, cadmium chloride (CdCl₂) treated for 12 h; group 3, T. terrestris extract-treated for 12 h; group 4, (amelioration) CdCl₂ for 12 h proceeded by T. terrestris extract for 12 h ; group 5 (mix), CdCl₂ plus T. terrestris extract-treated for 12 h; group 6, cadmium chloride (CdCl₂) treated for 24 h. We investigated the ameliorative potential at the cellular and molecular levels; apoptosis by using acridine orange/ethidium bromide staining, Annexin V/PI staining, cell kinetics, and induction response of some detox (SOD1, CYP1A1, and UGT) and anti-apoptotic (Bcl-2) genes. RESULTS: Cd decreased HEK 293 viability in a dose-dependent manner with with an IC₅₀ value of 15.06 g/ml Nuclear morphological analysis revealed that Cd-induced cell necrosis. It also positively induced detox genes and reduced Bcl-2. The inoculation of T. terrestris extract after CdCl₂ treatment reduced most of the Cd-induced toxicity. However, mixing or contaminating the extract with Cadmium rendered the ameliorative potential of the extract. CONCLUSION: the ameliorative action of the plant could be due to the presence of antioxidants and tribulin, which is the major ingredient in the plant. Our study recommends the use T. terrestris as a Cd-toxicity recovery herb. However, the current study needs to be confirmed at further research levels such as microarray, and the application on experimental animals (in vivo

In this thesis, we introduce and analyze a novel chaotic complex nonlinear system. The dynamics of this system is rich in the sense that our system exhibit chaotic attractors as well as periodic, quasi periodic solutions and solutions that approach fixed points. The stability analysis of the trivial fixed pointis stated. Numerically the range of parameters values of this system at which chaotic attractors exist is calculated. Lyapunov exponents are computed to classify the dynamics of this system. Symmetry, invariance and dissipation are discussed The principal target of this work is to introduce and examine a novel kind of complex synchronization. This sort may be called complex anti lag synchronization (CALS). There are surprising properties of CALS that do not exist in the writing, for example, (i) The CALS contains two sorts of synchronizations (anti-lag synchronization ALS and lag synchronization LS). (ii( In CALS the attractors of the main and slave systems are moving opposite or similar to each other with time lag. (iii) The state variable of the main system synchronizes with a different state variable of the slave system. We introduce and examine another kind of complex synchronization. We call this type complex modified projective lag synchronization (CMPLS). CMPLS, which is a more general case of synchronizations, is rarely studied or not mentioned up to date. In order to show this synchronizatio n, we study it to a system with certain and uncertain parameters of two chaotic complex n-dimensional flows possessing chaotic attractors with varying totally or partially in nonlinear terms The thesis consists of five chapters: Chapter one: In this chapter we show the preliminaries of nonlinear dynamical systems. We give a review of some basic concepts and definitions of nonlinear dynamical systems such as fixed points, Lyapunov functions, attractors, Lyapunov exponents, chaotic systems, hyperchaotic systems, secure communications, chaos and synchronization Chapter two: This chapter introduces and analyzes a new chaotic complex nonlinear system. This system is 6 dimensional systems of real first order autonomous differential equations. The dynamics of this system are contemplated. The Lyapunov dimension of the chaotic attractors of these systems is calculated. We presented different types of our system. Also, we introduced a definition of a new type of synchronization and studied it on our system. An approach proposed to analyze CALS of the complex system in light of Lyapunov function . Chapter three: The aim of this chapter is to investigate CALS with uncertain parameters. A definition of CALS with uncertain parameters is introduced for two identical chaotic complex nonlinear models. Based on Lyapunov function a scheme is designed to achieve CALS of chaotic attractors of these systems. The effectiveness of the obtained results is illustrated by a simulation example. The chaos synchronization results were employed to develop a simple application in secure communication. Chapter four: In this chapter, we present and investigate the definition of a new type of complex synchronization. We may call this type "complex modified projective lag synchronization (CMPLS)". We design schemes to achieve CMPLS of two chaotic complex systems with varying in nonlinear terms and with certain and uncertain parameters. We applied these schemes to study CMPLS on two chaotic complex nonlinear systems with certain and uncertain parameters. All the analytical results are verified by numerical simulation of our examples Chapter five: In this chapter, we conclude our main results and suggest some future works.

The organization of the roots, ganglia and the peripheral distribution of the cranial nerves in the fully formed embryos of Oreochromis niloticus are examined in the serial transverse sections. The analysis of the fibres carried by these nerves is studied. The results of this study demonstrated that the olfactory peduncle is absent. There is a complete optic deccussation. The ciliary ganglion is well formed and has one ciliary nerve. The nervus trigeminus has a single extracranial Gasserian ganglion. The intracranial geniculate ganglion of the facial nerve is partially fused with the ganglion of the anteroventral lateral line nerve. There is only one ramus palatinus that fuses with ramus maxillaries of the nervus trigeminus. The truncus hyomandibularis separates into three rami; opercularis, hyoideus and mandibularis. The nervus octavus runs ganglionated and has six branches and has no branch of macula neglecta. The nervus glossopharyngeus has one root, and has its own foramen and one extracranial petrosal ganglion. This nerve has three rami; ramus pretrematicus, ramus posttrematicus and ramus pharyngeus. The nervus vagus arises separately by two roots.It leaves the cranial cavity together with the posterior lateral line nerve through the jugular foramen. It has three branchial and one visceral trunks; each has its own ganglion. Each branchial vagal trunk gives rise to four rami; pharyngeus, lower pretrematic, upper pretrematic and posttrematic. There is an intracranial dorsal vagal ramus. There are two pairs of lateral line nerves; anterior and posterior and the middle lateral line nerve is lacking. The anterior lateral nerve divides into anterodorsal and anteroventral lateral line nerve. The anterodorsal lateal line nerve gives rise to three rami; ophthalmicus superficialis lateralis, buccalis and recurrence lateralis. The anteroventral line nerve fuses completely with the hyomandibular trunk of the nervus facialis.
