The objectives of this study are to obtain essential oil from Sedap Malam (Tuberose) flower via extraction method and to characterize the physical and chemical properties of the essential oil produced, such as density, rendement, and chemical composition. The extraction process was carried out by using methanol solvent. The ratio between Sedap Malam flower and the methanol solvent was 1:5. After the extraction process of the essential oil finished, the essential oil and the solvent were separated via a simple distillation process. The collected essential oil was then characterized using Gas Chromatography-Mass Spectrophotometry (GC-MS) apparatus and Fourier Transform Infra-Red (FT-IR) analysis to investigate the content of the essential oil extracted from Sedap Malam flower. The physical characterization results showed that the essential oil has average rendement value of 12.605 % and density value of 1.0905 g/mL. Additionally, organoleptic test was carried to test the response of respondents toward the color and odor/fragrance of the essential oil extracted from Sedap Malam flower. Most of the responses were included in categories of “Like” and “Really like”. Additionally, for the fragrance, most of response of the respondents for all the four samples of essential oil were in category of “Really like”.

The purpose of the work is to select a rational mode of slag formation in oxygen converters and chipboard. It should be based on the study of the influence of the chemical and component composition on the physical and chemical properties of slag, which determine its refining capacity. The physicochemical substantiation of the rational component and chemical composition of fluxes for the formation of a slag phase with given physical and chemical properties during the smelting of electric steel is given. It has been shown that when reducing the oxidation intensity of carbon in a metal melt and in the conditions of the extraction process for the formation of a stable gas-slag foam, the use of complex slag-forming mixtures containing natural minerals and man-made wastes on the basis of carbon and iron oxides is used. Increasing the efficiency of applying slag-forming mixtures with an adjustable CaO: CaCO3: C: FexOy ratio is achieved by implementing a method for introducing a disperse material into a carrier gas stream with an oxidizing potential, depending on the carbon content in the metal. It is established that the most rational for conditions of oxygen-converter melting is the use of materials intended for use, which contain lime with cigarette butter 15 - 20%. The material is fed to the bath at the end of the oxidation period with a decrease in carbon content to 0.15-0.2% with a significant increase in the temperature of the liquid steel. For conditions of steel smelting in the chipboard, the cigarette can be 40 60%.

Two new monomers of N-4-antipyrinyl methyl nadamic acid M1 and N-Procaienyl methyl nadamic acid M2 were synthesized from reaction of 4-Aminoantipyrine or procaine with methyl nadic anhydride at room temperature with dioxane as a solvent. The prepared monomers M1 and M2 were polymerized free radically with AIBN as initiator to corresponding polyamic acids P1 and P2, Which were converted to their sodium salt polymers P3 and P4 to enhanced their solubility's in water. The physical and chemical properties were studied for monomers and polymers, also FT-IR ,1H-NMR  and UV. Spectroscopy was characterized of M1or M2. The intrinsic viscosity was measured by  Ostwald viscometer at 30 0C  .The swelling %was measured and the controlled release rates of drug polymers were studied in different pH values at 37 0C.

Studying bitumen has always posed a challenge to researchers owing to its extreme complexity and unique properties. To classify it commercially and to determine bitumen grade, two standard empirical tests have been adopted within the European standardized bitumen binders system [EN 12591:2009 (2009) Bitumen and bituminous binders – Specifications for paving grade bitumens]: Softening Point (SP) and Penetration (PEN). The relationship between these two tests and the physical or chemical properties of bitumen is not well understood. For the first time, this study represents an attempt to build more understanding of such a relationship through a comprehensive study of the correlation between the two standard tests and many physical and chemical properties of bitumen. A second goal is to propose some predictive models for these two tests and compare their predictive accuracy. Therefore, 13 Straight Run Vacuum Residues (SRVR) samples from different geographical origins were analyzed to measure the following parameters: Dynamic Viscosity (VisDy), Conradson Carbon Residue (CCR), C5 Asphaltenes Content (AspC5), C7 Asphaltenes Content (AspC7), Elemental Analysis (including C, H, O, N, S, Ni, and V content), Simulated Distillation (SD), Fourier-Transform Infrared Spectroscopy (FT-IR), and proton nuclear magnetic resonance spectroscopy (H-NMR). Results of studying correlations using correlation matrix and Principal Component Analysis (PCA) have emphasized the prominent effect of asphaltenes content on the other properties and the results of SP and PEN. It has also shown the potential importance of the aliphaticity/aromaticity of bitumen. Then, four models were proposed for the prediction of SP and PEN: viscosity, FT-IR, H-NMR, and multi-parameter models. Partial least squares (PLS) regression was used for building all models, except viscosity ones. All SP models, except H-NMR model, exhibited very good accuracy compared to the standard method. On the other hand, PEN was more difficult to predict than SP and only the multi-parameter model of PEN showed relatively good accuracy of prediction.

Characterization of sodium alginate extracted from two species of brown seaweed (Turbinaria sp. and Sargassum sp.) has been conducted. The aim of the study was to evaluate physical and chemical properties of the two different types of sodium alginates produced from this extraction process. Extraction was conducted in alkaline solution followed by acid treatment with the following steps: sortation of seaweed, washing, alkaline extraction, bleaching, alginic acid and sodium alginate conversion, dehydration using isopropyl alcohol (IPA), drying, chopping and grinding. Each extraction was conducted in duplicate using approximately 1 kg of the raw materials. The physical and chemical properties of the final products (sodium alginate powders) were analyzed. The results of the analysis were as follows: the yield of alginate powder from Turbinaria sp. was 14.77% having water content of 13.48%; whiteness degree of 23.77%; and viscosity of 133.67 cPs while the yield of sodium alginate powder extracted from Sargassum sp. was 24.56% with water content of 12.69%; whiteness degree of 43.80%; and viscosity of 217.50 cPs. Both alginate powders had better physical characteristics compared to commercial grade alginate which had water content of 16.07%, whiteness degree of 29.37%, and viscosity of 102.67cPs.

Some fertilizers practices could be used to improve Baraka seed Nigella sativa L. as a medicinal crop like organic farmyard manure which efficiently applied to enhance growth and yield. Thus, a field experiment was conducted out at Research Station in Tikrit-Iraq during 2012/2013 season to estimate the impact of bat guano (0, 75, 125 and 175 kg.ha-1), seaweed extract as kelpak (0, 1, 2 and 3ml.l-1) on some physical and chemical essential oil components. Two factors were arranged in factorial experiment in randomized complete block design with three replicates. Thus, results revealed that application of bat guano at 125 kg.ha-1 was superior in enhancement of essential oil and its some physical and chemical properties as essential oil% of 1.53%, specific gravity of 0.95 g.cm-3, refractive index of 1.82, essential oil density of 0.93, dithymohydroquinone of 37.44µg.µl-1 and thymol of 25.73 µg.µl-1. Moreover, kelpak (3ml.l-1) significantly improved physical and chemical properties of essential oil which were essential oil% of 1.52%, specific gravity of 0.93 g.cm-3, refractive index of 1.72, and essential oil density of 0.94 and thymol of 25.92 µg.µl-1. Whereas, the main component dithymohydroquinone effected by application of 2 ml.l-1kelpak of 37.04 µg.µl-1. It could be recommended to use bat guano as alternative to chemical fertilizer fortified with foliar application of seaweed extract as kelpak so as to improve physical and chemical properties of essential oil.
