King Saud University is a public university located in Riyadh, Saudi Arabia. It was founded in 1957 by King Saud bin Abdul Aziz as Riyadh University, as the first university in the kingdom not dedicated to religious subjects. The university was created to meet the shortage of skilled workers in Saudi Arabia. It was renamed to King Saud University in 1982. The student body of KSU today consists of about 37,874 students of both sexes. Wikipedia.

The thigh adhesion quantitative measurement system is a sensor system for precisely locating fibers and/or bands of connective tissue formed between layers of body tissue, binding the layers together and not permitting them to glide over each other. This bonding is called an adhesion. The present system is designed to determine quantitatively the degree of adhesion and the location of high-pressure adhesion(s) such that medical removal procedures (e.g., liposuction) can be precisely performed. The system makes use of a scanning device having an array of pressure sensors, the scanning device being defined by a flexible plate wrapped by a belt to a patients limb, such as a thigh. A flexible cable connects the plate to a body-worn transmitter that wirelessly transmits real-time pressure distribution images received from the flexible plate to a computer for use by doctors preparing for the liposuction procedure.

The method for preparing metal nanoparticles includes preparing an extract of myrrh and mixing the extract with an aqueous solution including a metal salt. The mixture changes in color from light yellow to dark brown upon formation of nanoparticles. The extract of myrrh can be a water extract prepared by, for example, soaking a quantity of myrrh in water, filtering the soaked myrrh to obtain a filtered product, and then centrifuging the filtered product. The metal salt can be, for example, silver nitrate (AgNO_(3)). The metal nanoparticles can be spherical, spheroidal, elongated spherical, rod, and/or faceted. The metal nanoparticles can be used to treat Leishmaniasis (lesions) caused by Leishmania major.

The three-dimensional space-division Y-splitter for multicore optical fibers (MCF) is a 3-D device that depends on space-division splitting (SDS) by double-hump graded-index (DHGI) in a rectangular waveguide. It includes multiple single Y-splitters, each one being dedicated to one MCF core. Each Y-splitter layer has three stages, including an expander; a DHGI-SDS; and a separator. The net result of the Y-splitter is that the signal in a single multi-core fiber input has its optical power split 50-50 between two multi-core fiber outputs without an intermediate single-core single-mode fiber (SMF) conversion stage.


The present invention relates to extracts, compounds isolated from Cakile arabica for use in the treatment of ulcer and to pharmaceutical compositions thereof.


The method of ascertaining fully grown passive film formation on steel rebar embedded in concrete utilizes electrochemical impedance spectroscopy (EIS) to determine, in situ, the degree of passive film formation on steel rebar embedded in concrete. A length of steel rebar and a counter electrode are both embedded in a concrete slab. A reservoir is supported on an external face of the concrete slab and filled with an electrolytic solution. A reference electrode is then positioned in the electrolytic solution, and the length of steel rebar, the counter electrode and the reference electrode are electrically connected an EIS test instrument to perform electrochemical impedance spectroscopy. The quality of passive film formation on the length of steel rebar is determined based on comparison of the electrochemical impedance spectroscopy results with known passive film formation data.

The spectral method for quantifying hemoglobin fragility caused by smoking is based on decreased concentration of tryptophan and elevated concentrations of the biomolecules nicotinamide adenine dinucleotide (NADH), flavin adenine dinucleotide (FAD), and porphyrin in the presence of hemoglobin fragility. The method involves the steps of obtaining a blood sample from a patient who is a smoker; separating blood plasma from the samples; obtaining synchronous excitation spectra (SXS) of the blood plasma with a spectrofluorometer at a scan offset of 70 nm and at a scan offset of 10 nm; comparing the patients SXS with the SXS of normal control samples; and diagnosing hemoglobin fragility when the excitation maxima of NADH, FAD, and porphyrin are between 30% and 70% higher than the maxima for these metabolites in the normal control samples, or when the excitation maximum for tryptophan is 60% of the control sample.

The synthetic recycled plastic aggregate for use in concrete is a composite material containing between 30% and 50% by weight shredded recycled plastic, the balance being a filler embedded in a matrix of the recycled plastic. The recycled plastic includes polyethylene terephthalate (PET). The filler can include dune sand, fly ash and quarry fines. The synthetic recycled plastic aggregate is best used to make concrete with a water-to-cement ratio of at least 0.5.

The method of treating diabetic wounds using biosynthesized nanoparticles includes administering an effective amount of silver and gold nanoparticles to a patient in need thereof. The silver and gold nanocomposite is prepared by biosynthesis, i.e., by providing a first aqueous solution of a noble metal salt or a noble metal oxide; providing a second solution of an aqueous plant extract, and combining the first solution and the second solution to produce a solution including nanoparticles of the noble metal. The second solution includes a plant extract obtained from Solenostemma argel, Trigonella foenum-graecum and Cinnamomum cassia. The metal salt can include silver nitrate (AgNO_(3)) and chloroauric acid (HAuCl_(4)). Nanoparticles of gold and nanoparticles of silver are prepared separately, and then mixed to obtain a composition containing a gold and silver nanocomposite.
