Previous data indicated the effectiveness of silibinin as intraocular pressure (IOP) - lowering agent. The present study was performed to evaluate the interaction of silibinin with pilocarpine or cyclopentolate in lowering IOP in normotensive rabbits. The effects of topically instilled silibinin hemisuccinate solution (0.75%) alone or adjunctly combined with 2% pilocarpine or 1% cyclopentolate on the IOP of normotensive rabbits were evaluated using indentation tonometry. The results showed that 0.75% solution of silibinin was found more potent than pilocarpine (2% drops) in lowering IOP of normotensive rabbits, while their combination results in longer duration of action. Moreover, the elevated IOP values produced by cyclopentolate (1%drops

The purpose of this study is to demonstrate a simple high sensitivity vapor sensor for propanol ((CH3)2CHOH). A free space gap was employed in two arms of a Mach-Zehnder interferometer to serve as the sensing mechanism by adding propanol volume (0.2, 0.4, 0.6, 0.8, and 1) ml and to set the phase reference with a physical spacing of (0.5, 1, 1.5, and 2) mm. The propagation constant of transmitted light in the Mach-Zehnder interferometer’s gap changes due to the small variation in the refractive index inside sensing arm that will further shift the optical phase of the signal. Experimental results indicated that the highest sensitivity of propanol was about 0.0275 nm/ml in different liquid volume while highest phase shift was 0.182×103 i

    This study was conducted to provide a detailed description of the osteology features of Alburnus amirkabiri from the Qareh Chai river, markazi province, Iran. For this purpose, eight specimens of A. amirkabiri were collected from the Qareh Chai River by electrofishing and fixed in 4% buffered formalin after anesthesia.

An experimental investigation of the laser engraved process is carried out on.2.5 mm.thick acrylic Polymethyl Methacrylate (PMMA).using Carbon Dioxide,(CO2) laser. PMMA is a typical polymer.suitable for manufacturing microfluidic chips (Y shape). Fabrication parameters have an influence on the mechanical properties of the manufactured components. The effects of laser power (20, 40, and 60 W) and scanning speed (250, 350, and 500 mm /s) were evaluated on the microstructure and mechanical characteristics of microfluidic chips. With an increase in laser power and a decrease in scanning speed, the stacking of melt pools became more organized, pores were less visible, and mechanical characteristics improved. At a power density of 60 W and a s

Smear zone is usually formed around the prefabricated vertical drains (PVD’s) due to mandrel driving. The geotechnical properties of the soil in this zone exhibit significant changes that affect the performance of the PVD’s. The most relevant property in this respect is the coefficient of permeability. So far, no serious attention is paid to investigate the effects of shearing under large shear strains on the geotechnical properties of the soft soil in Fao region. In this study, an extensive laboratory testing program was conducted to assess the characteristics of the smear zone with an emphasis on the permeability coefficient of Fao soft soil. The results show that the permeability of the smear zone is about 70% of

Background: Temporomandibular disorder (TMD) is a painful condition that specifically affects the muscles, bones, and temporomandibular joint (TMJ). Pain can vary in intensity, ranging from mild to moderate or severe. It is often accompanied by limited movement of the jaw, resulting in a restriction of mouth opening.
Aim of the study: The purpose of this study was to determine the effect of low-level laser therapy on mandibular range of motion in patients with temporomandibular joint disorders.
Patients and methods: fifteen patients were randomly selected. The mandibular range of motion was evaluated for each patient before treatment and after 3 months, a dual-wavelength (810-980nm) diode laser

يعد القرن السابع الهجري /الثالث عشر ميلادي من أسوأ القرون التي عصفت بتاريخ أمتنا، وتمثل ذلك بالغزو الصليبي الذي كان في أوجه ومن ثم الغزو المغولي الهمجي الذي انهال على الأمة كما الجراد، أضيف لذلك ما كانت عليه الأحوال الداخلية من نزاعات بين الملوك والسلاطين، ورغم كل ذلك استطاع ثلة من العلماء الأكابر أن يدنوا التاريخ ويسطروه ليبقى محفوظاً للأجيال اللاحقة وصوناً لتراث الأمة العريق.

In this work, we are concerned with how to find an explicit approximate solution (AS) for the telegraph equation of space-fractional order (TESFO) using Sumudu transform method (STM). In this method, the space-fractional order derivatives are defined in the Caputo idea. The Sumudu method (SM) is established to be reliable and accurate. Three examples are discussed to check the applicability and the simplicity of this method. Finally, the Numerical results are tabulated and displayed graphically whenever possible to make comparisons between the AS and exact solution (ES).

Tendon is important structure of the human body, since it can sustain tensile loading. The primary function of this tissue is to stabilize the joints they attached to it during daily activities. As well as, tendon has viscoelastic properties that can determine their response to loading and restrict the potential of injuries. One of the major points that this paper works with is the study of the biomechanical behaviour of tendon in response to tensile loading to describe their biological behaviour. Also, conclude the mathematical expression that may illustrate the tendon behaviour. All of the experiments were made in Physiology laboratories / Medical College/ Al- Nahrain University on ten rats "Rattus Norvegicus" of [108- 360] gm weight f

The aim of this work is to develop an axi-symmetric two dimensional model based on a coupled simplified computational fluid dynamics (CFD) and Lagrangian method to predict the air flow patterns and drying of particles.  Then using this predictive tool to design more efficient spray dryers. The approach to this is to model what particles experience in the drying chamber with respect to air temperature and humidity. These histories can be obtained by combining the particles trajectories with the air temperature/humidity pattern in the spray dryer. Results are presented and discussed in terms of the air velocity, temperature, and humidity profiles within the chambers and compared for drying of a 42.5% solids solution in a spray chamber
