Annotation: Here are presented the data of GC / MS, ICP / MS, UV, STA studies of Azerbaijanoil from the Gunashli field in the Caspian Sea. According to the data of chromatography-mass spectroscopy, the relative distribution of n-alkanes of oil was determined to calculate the naphthenic oil passport from various horizons and depths. It is shown that oil is of paraffin-naphthenic type, hydrocarbon composition of oil samples varies depending on the horizon and the depth of occurrence. Oil is characterized as light, average catagenetic transformation and refers to the glandular type. Mother rock of sedimentary type are of the clay type. The studied geochemical characteristics of oil indicate a biogenic genesis and differentiation of oils by characteristic biomarker indicators, and also make it possible to predict the composition and type of oils in deposits with a simular geological structure.

A study was carried out to assess the ground water quality of urban area of Moradabad, a developing industrial city of Uttar Pradesh. The water samples were collected from bore wells, tube wells and hand pumps in research area. Various physico–chemical parameters were analysed. The pH value was in proximity to benchmarked NPI index value i.e. 1.0, while the NPI value for total alkalinity was found to be above one. The NPI values for calcium, magnesium, phosphate, chlorides, total dissolved solids, total hardness and nitrate were far below the critical NPI value of 1.00 Key Word: Ground water, Moradabad, urban area, water quality

Mango (Mangifera indica L.) and Avocado (Persea americana) fruits are rich in bioactive molecules that protect human cells against the detrimental effect of free radicals. The phytochemical analysis revealed the Presence of alkaloids, terpenoids, saponins, tannins, phenolics and flavonoids in both fruits. The free radical scavenging activity using total antioxidant capacity of the phosphomolybdenum method and hydrogen peroxide method were carried out on the water extracts of mango and avocado fruits. The order of antioxidant potential according to phosphomolybdenum method and hydrogen peroxide method was found to be higher in Mangifera indica L. than in Persea americana. The result for the total antioxidant capacity of the measured concentration (0.1 - 0.3 mg/ml) had mangifera indica showing the higher capacity with 0.372 mg Ascorbic Acid Equivalence (AAE) and Persea americana be with 0.265 mg Ascorbic Acid Equivalence (AAE). Further, the hydrogen peroxide scavanging activity was recorded maximum for Mangifera indica L. (70.67%) and (68%) for Persea americana. Phytochemical screening on the extracts revealed the presence of alkaloids, phenolics, terpenoids, flavonoids, saponins, and tannins. The results revealed that the antioxidant activity of mango fruit extracts is greater than that of avocado. The antioxidant activities of the same fruits type differ from place to place even in the same zone.

Polyacrylamides of varying molecular weights (very low, low, medium, high and very high) were synthesized using free radical polymerization and characterized by Infra Red (IR) spectroscopy, viscosity measurements, glass transition temperature (Tg) measurement and thermal gravimetric analysis (TGA). Thioglycolic acid and hydrogen peroxide were used as initiators to synthesis very low and low molecular weight polyacrylamides respectively. Molecular weights (medium, high and very high) polyacrylamides were synthesized using potassium persulfate and N,N,N',N'tetramethylethylenediaminesystem as initiators. The synthesis of medium, high and very high molecular weight polyacrylamides were achieved by increasing the concentration of acrylamide monomer. Fourier Transform Infrared Spectroscopy (FTIR) of polyacrylamides showed strong absorption at wave number 1655 cm -1 due to the presence of primary amide band. The results also showed that the increase in the intrinsic viscosity and glass transition temperature were proportional to the increase in molecular weight of polyacrylamide. On the other hand it can be seen an increase in molecular weight caused a decrease of weight loss %.
采用自由基聚合法合成了不同分子量(极低、低、中、高和极高)的聚丙烯酰胺，并通过红外光谱、粘度、玻璃化转变温度和热重分析(TGA)对其进行了表征。以巯基乙酸和过氧化氢为引发剂，分别合成了极低分子量和低分子量聚丙烯酰胺。以过硫酸钾和N,N,N′，N′四亚甲基二胺体系为引发剂合成了分子量为中、高、超高的聚丙烯酰胺。通过增加丙烯酰胺单体的浓度，可以合成中分子量、高分子量和超高分子量的聚丙烯酰胺。聚丙烯酰胺的傅里叶变换红外光谱(FTIR)显示，在波数1655 cm -1处，由于伯胺带的存在，聚丙烯酰胺具有较强的吸收。结果还表明，特性粘度和玻璃化转变温度的增加与聚丙烯酰胺分子量的增加成正比。另一方面，可以看出分子量的增加引起减重%的下降。

In this study deals with the isolation of natural dyes from hibiscus rosa sinensis and marigold flowers. There are different methods are used to synthesis the natural dyes on each flower. Then they are analysed by GC-MS, UV-Visible and IR Spectroscopy instrumental analysis. The instrument anlaysis reveals the structural conformation of natural dye collected from each dye. The mordant are important chemical component which is used to add with natural dye to enhance the colour strength of natural dye collected from the above flowers. In this project we use the alum, potassium dichromate, copper chloride and stannous chloride are used as mordant to increase the colour strength of each natural dye collected from the concerned flowesr. The colour strength is analysed with DATAColor Spectrophotomete. Wast fastness, Xenon fastness test are also carried out. From above test we conclude the strength of colour is increased by means of the stannous chloride mordent used compared to other mordants applied to the cotton dyed with the natural dyes extracted from the hibiscus rosa sinensis and marigold flower.
