  • Chemical Composition of the Essential Oil of Lavandula angustifolia from
           Syria

    • Authors: Gassan al-wassouf
      Abstract: Chemical composition of the essential oil of the flowers of  Lavandula angustifolia (Lamiaceae), grown in Syria was determined by GC/MS. The oil obtained by hydrodistillation, It was found that the essential oil yield is about (0,2462% ), was found to contain 66 chemical compounds the main ones are linalool(34.70%),Alcanfor(12.77%) , Eucalyptol (11.50%) , Borneol (9.82%) , Linalyl anthranilate (4.51 %) , Geranyl butyrate(3.02%).

  • An Analytical Relation Derivation for Threshold Voltage as a Function of
           Operation Time for Self-Quenching GM Counters

    • Authors: Abdullah Rastanawi, abdalhade sofan, Mohammed Alansi
      Abstract: At normal temperatures, it is known that The threshold voltage of GM counter tubes, which are filled mixture of inert gas and quenched organic gas, was shifted toward higher voltages during operation time because of  disintegration of quenched organic molecules. While threshold voltage of GM counter tubes, which are filled mixture of inert gas and quenched halogen, was shifted towards lower voltages during operation time because of  reaction of quenched halogen molecules with anode and cathode.  In this article, assuming that the counter tube operates at constant temperature and constant activity exposure, we have derived an analytical relation of Geiger threshold voltage as function of operation time. This relation indicates that the Geiger threshold voltages of the tubes which contain organic gas are exponentially increased during operation time. the Geiger threshold voltages of the tubes which contain halogen are exponentially decreased during operation time. Keywords:  analytical relation ,threshold voltage, operation time, GM counter.

  • The Effect of NADH in the Oxidization of Tetra Methyl Benzidine in the
           H2O2 /Peroxidase System

    • Authors: Ebrahem Naif Ismail
      Abstract: More than 1000 chemical material, which used in deferent categories, such as (cosmetic, detergent, pesticides, etc) may cause cancer to humane as will as animal, were recognized . There carcinogens can be divided into two group: The first group: material causes cancer without enzyme affection. The second group: chemically inert materials, which exhibit its Carcinogens action after the effect of enzyme during metabolism inside the living body. And such materials are aromatic amines. Metabolized aromatic amines under the effects the enzymes by different path way and  the Peroxidase path is one of these path way, in Which aromatic amines changed from non active into active form, Which can interact with the larges bio molecules as nucleic acids DNA and inhibited it. The aromatic amines metabolized under the effects the enzymes by different path way. and the Peroxidase path is one of these methods, in which aromatic amines changed from non –active into active form ,which can interact with larges biological molecules as nucleic acids DNA and inhibited it, Intra cellular components performed multi- functional such as Glutathione GSH, NADH. It was chosen because of the high damper NADH concentration in the cell (10-3M) and its spread in all types of tissues NADH(H+) inhibit large number of products of oxidation of the  Aromatic amines cancerogenus compounds, such as benzidine Substrate and its derivatives such as3,3',5,5' tetra methyl benzidine  in  Competitive path way. NADH: nicotine amide adenine dinucleotide (reduced form). Keywords: tetra methyl benzidine, Peroxidase, inhibition, nicotine amide adenine dinucleotide.

  • Analysis of Nitrate Levels in the South East Coastal Areas of Lake Tana
           using UV-Visible Spectrophotometer

    • Authors: Worku Kegne
      Abstract: Nitrogen compounds added to the terrestrial environment from agricultural sources impact fresh water ecosystems. Nitrate contamination resulting from deposition of nitrates onto soils and plants, with subsequent leaching out of the water shade may enhance the harmful processes of eutrophication in Lake Tana. The aim of this research is to analyze the level of nitrates in Lake Tana. The level of nitrate (NO3-) in samples from different sites within the Lake was determined in dry season with standard method using Uv-Visible spectrophotometer during March/April. Nitrate (NO3-) values for water samples in Lake Tana ranged from 0.24- 2.21 mg/L NO3-. The average nitrate concentrations of the different sites in mg/L Nitrate are as follows; Rib =2.21 ± 0.21, Gumara = 2.09 ± 0.26, Gelda = 2.12 ± 0.20, Mehal Zegie = 0.24 ± 0.12, and Enfraz =1.32 ± 0.17. The value of nitrate (NO3-) was higher in the sites of east coastal river mouths of Lake Tana (Gumara, Gelda, and Rib).The southern part of the Lake has lower concentration of nitrates than those on the east coast.  Agricultural practice in the east and urbanization in the south of the lake must have contributed for higher nitrate levels in these areas.Appropriate pollution control measures should be taken in our agricultural practices and urban waste disposal systems in the lake catchments though the levels encountered in this work for now are within the regulatory threshold set by EPA (45 mg/L NO3-). Key words: Nitrate, Euthrophication, Met hemoglobin, Phenol disulphonopic acid.

  • Chemistry of Caffeine in Coffee and Its Determination Using UV/Vis
           Spectrophotometer: A Review Article

    • Authors: Fisseha Gebrewold
      Abstract: This review is all about the chemistry of caffeine and some methods applied to determine the concentration of caffeine in coffee. Coffee is the major sources of caffeine. In pure form, caffeine is a crystalline white powder moderately soluble in water and in a wide range of organic solvent such as ethanol, ethyl acetate, methanol, benzene etc. When it is removed from the source plants and reduced to its most natural state, it forms a white powder. Consequently, the ingestion of caffeine, an important ingredient of coffee as well as tea, has become a daily habit for many persons. Among different methods used to determine the concentration of caffeine in coffee, spectrophotometric method is an effective method used for the determination of caffeine in Coffee raw. The method was found to be fast, simple, cost effective and environmental friendly for the determination of caffeine in aqueous solution of coffee with satisfactory results. Keywords: Coffee, caffeine, UV-Viscible spectrophotometer
