Prof. Dr. Amin Malik Shah Abdul Majid John Curtins of Medical College, Australian National University, Canberra – Australia Universiti Sains Malaysia (USM) Development of Herbal Pharmaceutical Targeting Angiogenesis for Cancer Therapy: Canssufive Nuvastatic a Case Study Angiogenesis is a process of new blood vessel development, and it plays a central role in a significant proportion of human diseases. Cancer growth and metastasis are highly dependent on angiogenesis to obtain vital nutrients and oxygen. Hence inhibiting angiogenesis is a useful strategy in cancer therapy. Canssufive Nuvastatic is an herbal drug made from the standardized herbal extract of Orthosiphon stamineus, a popular herb commonly used in Malaysia and South East Asia to treat diabetes, hypertension, gout and kidney stones. The extract has been shown to target key angiogenesis receptors and modulators and has been found to inhibit tumor growth in xenograft tumor model of colon, lung, breast and pancreatic cancer. The Orthosiphon stamineus herb has been carefully cultivated to ensure the presence of marker compounds within the specified limit. Canssufive Nuvastatic has completed phase 1 clinical studies and currently is undergoing phase 2 clinical studies in breast and colon cancer in combination with standard chemotherapy regimens. Canssufive Nuvastatic is a potential herbal based drug that may be useful in treating the cancer disease.

Conference Abstract Book

Assoc. Prof. Dr. Haider Butt School of Engineering, University of Birmingham, Birmingham, UK Contact Lens Sensors based Wearable Diagnostics The key challenge for producing nanostructures based commercial applications is the scaling up of the fabrication process. We present the fabrication of dye based nanostructures by using the fast and commercially viable method of holographic laser ablation. In this method we use a single beam of a nanosecond laser, which after reflecting from a mirror self-interferes. This results in an interference pattern which can be used to ablate a well-ordered grating in thin films. The period of the grating is determined by the incident wavelength (λ) and tilt angle (θ) of the sample with respect to normal incidence. In this manner we recorded various holographic nanopatterns onto transparent substrates, such as glasses and commercial contact lenses. Using this quick, scale and economical method we produced several wearable nanophotonic sensors. These contact lens based holographic sensors can be used for monitoring the eye curvature and pressure of glaucoma patients. The holograms have also been functionalized to sense glucose concentrations in the tears of diabetic patients.

Assoc. Prof. Ts. Dr. Nik Noriman Zulkepli Advanced Polymer Research, Centre of Excellence Geopolymer and Green Technology, Faculty of Engineering Technology, Universiti Malaysia Perlis - Malaysia Polymer Recycling: Transforming an Environmental Risk into Sustainable Green Composites Polymeric materials (plastics and rubbers) comprise a steadily increasing proportion of the municipal and industrial waste going into landfill. Development of technologies for reducing polymeric waste, which are acceptable from the environmental standpoint, and which are cost-effective, has proven to be a difficult challenge due to complexities inherent in the reuse of polymers. On 2020, the world will consume about 36.7 million tonnes of rubber and 16.4 million tonnes of it will be natural rubber, according to the latest figures from Singapore-based research body International Rubber Study Group (IRSG). By then, 91% of natural rubber will be supplied by Asia-Pacific countries. About 407 million tonnes of plastic was produced in 2015: triple the amount produced in 1990. If current trends continue, 1600 million tonnes of plastics will be produced annually in 2050 (EMF, 2017). Despite the best efforts, most recyclable polymer (such as plastic) still end up in landfills. Once landfilled, materials are mixed with dirt and slowly break down over time and difficult to decompose. The rubber industry has been faced with its own unique challenges when it comes to recycling. Example, synthetic rubber is difficult to manage due to three main factors such as large volume of waste, durability of the material and hazards involving handling and storage. In modern world, is a key goal of researchers and scientists in both industries to invent a product that not only meets the needs of manufacturers and consumers, but which actively reduces environmental issue.

PART 6: LIST OF ABSTRACT Synthesis and Characterization of Mesoporous Hydrotalcite-Alumina Membrane for Carbon Dioxide Enrichment A D Wiheeb1, S W Shakir 1 and M R Othman2 1

Chemical Engineering Department, College of Engineering, Tikrit University, 34001 Tikrit, Sallahaddin, Iraq 2 School of Chemical Engineering, Universiti Sains Malaysia 14300 Nibong Tebal, Penang, Malaysia

Abstract. Hydrotalcite material was incorporated to enhance the carbon dioxide (CO2) affinity of the alumina membrane for CO2 separation from different gas mixtures. The crack free mesoporous HTalumina (~10 μm) porous membranes were successfully synthesized on surface of α-Al2O3 disc support using the sol-gel and dip-coating techniques. The unsupported membranes were characterized for the presence of HT, surface functional groups, surface topography and morphology, pore size and CO2 adsorption capacity. These characterizations were done using X-ray diffraction (XRD), Fourier Transform Infrared (FTIR) spectrometry, scanning electron microscopy (SEM), Brunauer-Emmett-Teller method (BET) and Thermo gravimetric analyser (TGA) techniques. The modification of alumina membrane with HT enhanced CO2 separation performance. The CO2 permeance was higher than that of methane and nitrogen. While the permeance of hydrogen was almost same to that of CO2 even though the hydrogen molecule was smaller than the CO2 molecule. Indicating that the gas transport through the membrane was predominantly surface adsorption. The mesoporous Hydrotalcite-alumina membrane overcame the Knudsen limitation and produced the highest permselectivity of 2.16 for CO2/CH4 system at 30ºC temperature and 100 kPa pressure difference.

Abstract. Water pollution by thallium and its derivatives have caused great concern in recent years, and there is a growing need for improved adsorbents for their removal. The aim of this study is to prepare a modified form of γ-alumina nanoparticles bounded to 2, 4-dinitrophenyl hydrazine for the removal of thallium (I) ions from aqueous solutions. The modified-γ-alumina nanoparticles were prepared by an immobilization method of 2, 4-dinitrophenyl hydrazine on γ-alumina nanoparticles coated with sodium dodecyl sulphate. The modified adsorbent was characterized by Fourier Transform Infrared spectroscopy, Scanning electron microscope, Transmission electron microscope, and Brunauer-Emmett-Teller for surface area analysis. Column adsorption studies were performed to obtain the applicability of the modified γ-alumina nanoparticles for removal of thallium (I) ions from real water samples. Kinetic studies followed the pseudo-first-order kinetic model for both adsorbents with low energies of activation indicating physical type of adsorption. Column studies using the modified-γ-alumina sorbent show highly efficient removal of thallium (I) ion from real water samples and gave a high recovery percentage up to six cycles on the same column. So, the sorbent was easily prepared and it was successful in enhancing the efficiency of the removal process making it an attractive candidate for the rapid and cost-effective removal of thallium ions in water treatment adsorption processes.

Abstract. Kwashe industrial area in Summel district, Duhok city, Kurdistan region-Iraq is relatively new and considered the only industrial area in Duhok city which include various factories such as petroleum refineries, dying, tanning, cement, recycling of steel in addition to large municipal waste separating factory that produce huge amount of wastes in huge landfill with high leachate. Therefore ten artesian wells were chosen nearby and downward industrial area to study the impacts of industrial effluents and landfill leachate in contaminations of these wells. The results showed. The sulfate content is under risk limit of WHO (3-150 µg/L) in ground water, but there is evidence that a little contamination plume is created in Girresh 28.63 ± 1.25 mg/L location. The Cl as typical recommended by WHO in ground water is 1-70 mg/L and are low in 5 artesian wells upper industrial are and magnified in the rest 5 artesian wells downward industrial area and high levels recorded in Girrash 30.33 ± 1.53 mg/L. WHOstandard of NO3 in ground water is 2-20 mg/L, the locations Kwashe 3, 4, 5 is better site of NO3 in upper industrial area ranging between 5.13 ± 0.15 to 5.50 ± 0.20 and the third wells are save for drinking according WHO standards which must be under 10 mg/L are Kwashe 1, 2 and Sarshour ranging between 9.67 ± 0.1 and 9.70 ± 0.20 mg/L. The rest four wells Girresh, Marina, Moqeble, and Sarshour located down ward industrial effluents and landfill leachate are significantly affected toward increasing to reach hazardous levels in three location Sarshour 19.70 ± 1.45 mg/L, Marina location 22.67 ± 0.85 mg/L and the center of toxin plume recorded in Girrish of 55.33 ± 0.25 mg/L which is not save as drinking water for adults and Cattle babies according WHO standards. The typical soil properties like high pH values 7.9, huge amount of active/total CaCO3 % 62.62 and high clay content 381.68 g/kg, makes the condition optimum for heavy metal precipitation and rendered it inactive in sorption site of soil colloidal system and prevent it to reach ground water table. However, the little concentration of heavy metal is varied from location to another to give an index that the pollution is sever and create a toxin plume downward location but not exceeded typical standards of WHO for drinking water.

Experimental Research of The Frictional Condition in The Pipes Extrusion Process Y Ig Kosmatskiy1, A S ALKhuzaie1,2, M J ALJumaili1 1

Department of Materials Technology, South Ural State University (SUSU), 76 Lenin Prospekt, 454080 Chelyabinsk, Russia 2 Wasit University, Wasit, Iraq

Abstract: The article demonstrated the results of an experimental study of the pipe extrusion process using the method of coordinate grids. The estimation of the influence of separate conditions of friction on the contact surfaces of the deformable material and the pressing tool on metal flow pattern. The calculation of the forming operation is made for extrusion process stages. It is shown that the deformation proceeds non-uniformly. At the same time, due to the creation of favorable conditions on the contact surfaces with the use of the lubricant, the deformable sample differs uniformly in the distribution of the coordinate grid along the wall thickness of the tube’s sample. The boundary stagnation zones are identifying. It has been demonstrated that the front portion of the sample tubes is not fully worked through the wall thickness. While, the rear section is characterized by a dense grid structure. This in combination allows us to indirectly judge the possible anisotropy of the properties along the body of extruded pipes. It is proved that the using of lubricants on the contact surface: the press needle – inner surface of the sleeve will not have a significant effect on the extrusion force, and can be used mainly to ensure the durability of the press tool and to perform the quality characteristics of the inner surface of the extruded tubes. It was concluded that, first of all, the requirements for thermo-technical properties: heat capacity and thermal conductivity, and, secondarily, frictional, must be imposed on lubricants used for coating the inner surface of the sleeve and, accordingly, providing a separation layer between the press needle and the sleeve.

Buckling and Pre Stressed Vibration Analysis of Laminated Plates Using New Shear Deformation Widad Ibraheem Majeed and Dr. Ibtehal Abbas Sadiq 1

Mechanical Dep - Coll of Engineering - Univ Of Baghdad, Iraq

Abstract. buckling stresses and natural frequencies of cross-ply laminated composite plates are analyzed using new higher order shear deformation theory. The new displacement field proposed by J.L. Mantari et al depends on a parameter ‘‘m’’, whose value is determined so as to give results closest to the three dimensions buckling solutions. A set of fundamental dynamic equations of a twodimensional higher-order theory for rectangular laminated plates made of elastic and orthotropic materials is derived through Hamilton, s principle, these equations of motion are applied to solve the vibration and pre-stressed free vibration problems of laminated composite plates after buckling solution. These equations are solved using Navier-type for simply supported boundary conditions. It was observed that this theory gives results close to three dimensions elasticity solutions and those obtained by existing shear deformation plate theories.

Conclusions: The present result shows that treatment with phenolic extract of cyperus rotundus rhizomes in ISO injected rats significantly attenuates induced myocardial infarction.

Water Absorption and Fatigue life of an Epoxy Composite Reinforced by Glass Fiber Ahmed Sahib Mahdi, Najah Rustum Mohsin 1

Southern Technical University (STU), Iraq

Abstract: In the current paper, the influence of absorbed water amount on fatigue life and some mechanical properties was investigated. The epoxy-10 resin was used as a matrix and glass fiber was used as a reinforced material. Two percentage of glass fiber (25 and 35%) was performed. Woven Roven method was performed to arrange the glass fiber inside the matrix. Two types of solutions were used to immerse the samples which were distilled water and salt water. The experimental results showed the lower amount of absorbed water was observed by using salt water solution compare with distilled water due to that the salt water has higher density compare with the other. On the other hand, when the reinforced material was a large percentage, the absorbed water amount was the big amount due to a big probability of cavities were found. Consequently, when the big amount of glass fiber was used, then higher hardness value was obtained.

Experimental Research of the View of the Metal Flow in the Pipes Side-Extrusion Process Y Ig Kosmatskiy1, M J AL Jumaili1, A S AL Khuzaie1 1

Department of Materials Technology, South Ural State University (SUSU), 76 Lenin Prospekt, 454080 Chelyabinsk, Russia

Abstract. The article demonstrated the results of an experimental study of pipe extrusion process with lateral flow using the method of coordinate grids. The calculation of the forming operation is made for extrusion process stages. The following features of the extrusion process are noted: axial asymmetry of deformations and increased unevenness of deformations due to this. It is shown that the front portion of the tube sample is not fully worked through the wall thickness. The distribution of the grid along the thickness of the wall of the sample pipe, due to the presence of a stagnant zone, preserves the heredity of this region and forms a corresponding uneven distribution of the longitudinal and transverse bands of the coordinate grid, directly, in the lower part of the plane under consideration. The results obtained make it possible to indirectly judge the presence of anisotropy of the properties of the sample tubes produced by the pressing method with lateral flow. It is noted that, in order to create favorable conditions for the deformation of metal during the extrusion process with lateral flow, rational use of the double-sided extrusion scheme, which in turn will eliminate the stagnant zone of metal in the bottom of the container and, accordingly, ensure homogeneity of the grid distribution along the pipe wall thickness sample.

Abstract. Time-resolved studies of silylene, SiH2, generated by laser flash photolysis of phenylsilane, PhSiH3 have been employed to obtain rate constants for its bimolecular reaction with deuterated hydrogen, D2. The monitoring laser was tuned to 17259.50 cm-1, corresponding to a known strong vibration-rotation transition, A (1B1) ← X (1A1), in the SiH2 absorption band. The SiH2 concentration-time profiles were recorded for mixtures of phenylsilane and various partial pressures of D2 at temperatures in the range 300-553K. At three different temperatures, data were recorded in a series of runs for second order plots at 10 Torr total pressure. In addition to those experiments another set of runs was carried out at each temperature, in which the total pressure (SF6) was varied in the range 1 to 100 Torr in order to test the pressure dependence of the second order rate constants. In these runs second order kinetic behaviour was observed. The rate constants were found to be pressure independent. Negative activation energy of -0.48 ± 0.04 kcal mol-1 was obtained for this reaction. The isotopic ratios obtained from experimental data for SiH2/SiD2 + D2/H2 were compared with those of Transition State Theory and found to be in reasonable agreement when the Transition State structure of Gordon et al was used.

Abstract. Nanostructured Cr-Al-N thin film with different Al content (0 to 50 at. %) were deposited. The structural evolution and morphological changes were performed. The tribological performances were evaluated using a ball-on-disk type Oscillating tribometer. The tests were carried out under normal loads of 2, 10 and 20 N respectively. The results showed that the crystallite size and roughness continuously decreased with increasing Al content, exhibiting a value 30 at. % Al. The wear rate tends to decrease with the increasing of Al content to reach a lowest value 30 Al. The wear rate and friction coefficient were lower in the samples with 30 at. % Al content. The improved friction and wear resistance were attributed to the grain refinement strengthening mechanism at 30 at. % of Al.

Abstract. The structural evolution and tribological behavior of the nanostructured alumina Alpha (αAl2O3) powder, formed by calcinations of gibbsite (Al2(OH)6) at different temperatures (273-1473 K) were reported using X Ray diffraction, XPS, MEB and Type ball on Disk tribometer. XRD analysis indicates that the transformation sequence involves the formation of κ-Al2O3 as an intermediate phase between χ- and α-Al2O3. The crystallite size of treated alumina (α-Al2O3) is as small as 10 nm after calcinations at 1473 K. The sliding wear rate and wear coefficient of friction were lower in the nanocrystalline samples calcined at 1473 K at same applied load (2, 8 or 16 N). The enhanced friction and wear resistance is endorsed to the finer microstructure, hardness of the sample calcined at 1473 K.

Abstract. In this work Cr-N, Cr-Zr-N and Cr-V-N f coatings were elaborated by RF reactive magnetron process. The structures, morphology, mechanical and tribological properties of films as a function of Zr and V content were examined by RDX SEM, AFM, nanoindentatin and scratch tests. The CrN films display only a mixture of tow-phase microstructure, containing a NaCl (c.f.c type) of CrN phase and a hexagonal Cr2N phase, as evidenced by DRX. The results disclose that the hardness and young modulus of films were found to depend hardly on the Zr and V contents. As the Zr content increases, the dense and compact structure is developed with a low surface roughness; however the addition of V presents a rough surface. Also, the hardness (maximum hardness is 26.3 GPa) are largely improved in comparison with CrN and Cr-V-N films. However, the mechanical property of CrN was deteriorate with adding of V content. Rhe CrZrN films presented a rest wear resistance.

Influence of Sample and Ion Beam Potential on the Mirror Effect Phenomenon at Low Accelerated Voltage Muayyed Jabar Zoory, Emad Hameed Ahmed1, Saad Khalid Rahi Department of Physics / College of Science / Mustansiriyah Univ., Iraq-Baghdad

Abstract. Here, the behavior of scanning ion was treated by a simple mathematical control as a function of beam potential and sample potential. The motion equation of the vertically incident ion was derived using energy conservation law. The importance of mathematical derivation comes connecting the irradiation parameters of the scanning beam on one hand and the parameters on the other hand. This achievement was performed through adopting the charged-disk model. The results showed that the current of ion beam has a significant influence on the produced image by ion mirror effect in comparison with other beam parameters that can be used in controlling the ion mirror effect images at minimum values of scanning potential.

Determination of Deliverability Equation and IPR for Siba Gas Condensate Reservoir in Iraq – Case Study Jreou, Ghazwan N S College of Engineering, University of Kufa, Iraq

Abstract. Gas condensate reservoirs are actively being discovered and are fast becoming important throughout the world. Their significance has increased further with the emergence of deep drilling and modern technologies. Scientific research and publications have also broadened our understanding of their flow behavior. A well deliverability equation is important to measure production capabilities under certain conditions of reservoirs and bottom hole flowing pressures. This equation is a significant tool to provide information for determining the reservoir rate–pressure behavior of wells. Therefore, this work offered a gas deliverability equation for the Siba Gas Condensate Field in Iraq, particularly for the Yamama Formation Reservoir. The equation was obtained according to the methods of Houpert and Rawlins–Schellhardt for pressure-squared and pseudo pressure techniques. Results revealed that despite the lack of relevant information, the obtained deliverability equation was acceptable with mean absolute percentage errors (MAPEs) equal to 0.145053, 0.054328, 0.050463, and 0.046233 relative to available measured data. To verify the results, we selected a generalized inflow performance relationship (IPR) from the literature and compared its outcomes with the constructed ones. Good and acceptable results were obtained with MAPEs equal to 0.001102726 and 0.001052612. A future IPR was derived to predict the flow behavior of the target reservoir production with a range of reservoir pressures no less than the current reservoir pressure of 8593 psia. The prediction was aimed at avoiding the loss of a significant amount of condensate in the reservoir because its measured dew point pressure is equal to 9021.35 psia. The constructed future IPR was compared with the generalized future IPR, and both showed good agreement with a MAPE equal to 5.234%.

Abstract. Skin degenerative diseases, which lower the quality of life has become a colossal challenge across the globe. Despite significant number of such diseases including vitiligo and psoriasis, there has been no great progress in finding a cure to these diseases. Mesenchymal Stem Cells (MSCs) seem promising in this front as MSCs possess unique immunomodulatory properties. There have been preclinical and clinical studies suggesting the use of MSCs for the treatment of atopic dermatitis (AD), a prominent inflammatory skin disease. MSCs can be derived from multiple sources including adipose tissue, dental pulp, umbilical cord, placenta, peripheral blood, endometrium, synovium, and skin. However, stem cells isolated from hair follicle seem to be the closest to the original melanin producing cells. The differentiation of these stromal cells into melanin producing cells holds a promising cellular therapy for skin degenerative diseases. This study aims to differentiate human CD34+ melanocyte stem cells into melanin producing cells. The differentiation has been characterized by probing for the expression of proliferation markers dopachrome tautomerase (DCT) and microphthalmia associated transcription factor (MITF) and differentiation markers melanocytic antigen (PNL2) and tyrosinase (TYR) through the differentiation process. The results confirm the differentiation of the enriched CD34+ melanocytes into melanin producing cells. Melanin production was confirmed by ELISA to estimate melanin content.

Abstract. This study investigated the effect of using nano CaCO3 and nano SiO2 as partial replacement of cement on the mechanical properties, durability and flowability of concrete. Nano materials were added in four different dosages of 1%, 2%, 3% and 4% by weight of cement in concrete mixture. Mechanical properties of hardened concrete (compressive strength, flexural strength and split tensile strength) have been done after 28 days of water curing. Also water absorption test was carrying out for obtaining the durability properties of concrete specimen. Slump flow for fresh concrete was measured for all mixes. Binary combination of nanoCaCO3 + nanoSiO2 were also studied the combined effect of the nano particles. The results showed that incorporation of nano CaCO3 and nano SiO2 particles lead to increase the packing and enhance the mechanical properties and durability of concrete. A significant performance was observed in case of nano silica addition to the concrete in comparing with nano CaCO3. The results showed that the workability of fresh concrete was decreased by increasing the content of nano particles.

Abstract. The current work deals with synthesis of natural polymer hydrogels (Sodium alginateChitosan- Arabic Gum) as beads. The beads are formulated with different polymer proportions depending on the experimental central composite (design) Response Surface Methodology (RSM) has been used. The degree of swelling in acidic and neutral mediums was investigated, analyzed, modeled and optimized statistically. A typical drug (Allopurinol) was loaded by using optimized polymer formulations. The loading capacity and the in vitro release profiles were estimated. The shape and morphological analysis for the beads before and after drug releasing have been investigated also by using Scanning Electron Microscope. The results obtained confirmed that Arabic Gum content was a significant parameter in the swelling processes regardless the pH of the swelling media. Thus, swelling indices of the beads were higher in acidic medium (pH 3.9) compared to that once in (pH 7.1), to indicate a pH-sensitive swelling behavior. An optimum RSM results for swelling indices of 504.98 % and 207.97 % were obtained in acidic and neutral medium respectively. The in vitro drug release showed equilibrium after 12 hours where as (66.1- 85.7 %) and (44-54 %) was released at pH 3.9 and 7.1 respectively. The SEM analysis of the polymer beads confirmed that the beads had lost their shape due to erosion and swelling activities after releasing of the drug.

Abstract. A batch leaching test was performed to measure the leached concentrations of chromium (Cr), lead (Pb), arsenic (As), nickel (Ni), copper (Cu), cadmium (Cd), and zinc (Zn) from dredged sediment samples from the Leeds & Liverpool canal/ Liverpool section. The obtained results confirmed that the leached concentrations of the studied heavy metals were less than the toxicity levels and followed the order: Zn > Cu > Ni > Pb > Cr > As > Cd. The highest concentration was of Zn (about 0.28 mg/L), followed by Cu at a concentration of 0.17 mg/L, while the lowest concentration was of Cd at 0.009 mg/L. Therefore, the dredged sediments from this canal can be safely relocated in dumping sites such as landfills, or reused such as by spreading on agricultural fields.
