Abstract:：In this work the analytical results of water samples taken from Itiberê River and its affluent Village River are presented. The settlement of Paranaguá occurred, among other places, along these two rivers, which caused deforestation of Atlantic Forest areas for residential construction and commerce in general. To evaluate this environmental impact, analytical tests were carried out in which the nitrogen and phosphorus macronutrients, considered the eutrophic agents, were quantified as well as other physical and chemical parameters such as pH, turbidity and the total residue. For that, we used the potentiometric, turbidimetric, gravimetric and spectrophotometric analytical techniques. These analytical results showed that in some sample points the degradation process is relatively high due to the alteration of pH values and ammonium ion. The excessive presence of the phosphate ion in some sample points, that is, values close to 40 times higher than the values recommended in CONAMA Resolution 357/2005 [1], may be due to uncontrolled demographic expansion, where sewage is directly dispensed into the riverbed.

Keywords: anthropogenic activity, nitrogenous compounds, phosphate compounds.

Abstract:：Urea-formaldehyde resins (UF resins) were prepared by a two-stage reaction. The comparative analysis were made of the resulting laboratory samples with some commercial samples. Some of the drawbacks of UF resins, such as poor adhesive strength, especially in moisture or humid environments and high free formaldehyde emission (FE).In order to reduce the FE, lowering urea/formaldehyde (U/F) mole ratio in the synthesis of the UF resin was done. In this study, synthesis of UF resins was carried out following the conventional alkaline-acid two-step reaction with a second addition of urea, resulting in the following U/F mole ratio: 1:2.60, 1:2.70, 1:2.30, 1:2.04, 1:1.97, 1:2.13 and 1:2.90. Remarkably, the free formaldehyde was found to decrease with increased mole..........

Abstract:：Presence of arsenic was assessed in the waterbodies of Pakur town of Jharkhand, India. The objective of this study is to assess the quality of water especially in the context of arsenic of the said area where water is used for domestic as well as agricultural purposes. The disposal of untreated wastes from various resources have posed an alarming threat to our environment due to metal pollution. These wastes generally containing in addition to Arsenic, several other poisonous metals such as Mercury, Lead, Chromium etc. highly injurious to health are finally discharged to ground water. In the present investigation quality of water with regard to arsenic pollution has been tried to know in various populated areas of Pakur town of Jharkhand..

Abstract:：The mechanism of corrosion inhibition of aluminium by 2 M thiourea in 0.08 M potassium hydroxide was investigated using gasometric, gravimetric and scanning electron microscope (SEM) methods. Synergistic measurements were also carried out, The result showed that the rate of hydrogen gas evolution and weight loss was greatly reduced while inhibition efficiency increased. These effects were seen to increase as time prolonged. SEM results showed the vivid presence of the absorbed inhibitor molecules on the surface of the metal protecting it from corrosion attack.

Abstract:：Acid hydrolysis of corn stalks offers enormous opportunities to convert abundant agricultural residues to valuable chemicals. This paper investigates the effect of using dilute acids to produce reducing sugars. 5% w/v corn stalk was hydrolyzed with Acetic acid, HCl and H2S04 at different concentrations of 1% v/v to 2.5% v/v. Results show that maximum percentage reducing sugar of 36.11% was obtained for 1.5% v/v sulfuric acid while maximum reducing sugar of 32.23% and 23.32% were obtained for 1.5% v/v HCl and 2% v/v acetic acid respectively. A second stage acid hydrolysis that involves the re-suspension of residues after an initial hydrolysis with another acid was also studied by combining different acids. A Sulfuric acid-sulfuric acid double step hydrolysis gave a maximum reducing sugar of 49% while other combinations of acids led to increased sugar yields of 40% and above..

Abstract:：The action of heat on the aqueous solution of ammonium acetate as well as in presence of silica and alumina at 95 ± 5ºC under prebiotic drying-wetting conditions has been investigated for the plausible formation of amino acids. The reaction products were analyzed and characterized by chromatographic ( PC and HPLC ) and spectroscopic methods. Reaction system heated up to 100hrs, showed the best formation of lysine, aspartic acid, serine, glycine, glutamic acid, α-alanine, β-amino butyric acid, valine, isoleucine and leucine. In presence of silica and alumina accelerated the formation of amino acids and three new products were observed in the concentrate of the reaction system. Thus, the study is an attempt to explore the possible role of metal oxides in the prebiotc formation of amino acids, which constitute the main matrix of the living systems.
