    Opis:
    The objective of the research is to identify the status of physico-chemical parameters of the soil in the surrounding area of Nakki-Lake, Mount Abu, Rajasthan, India. Soil parameter plays a major role in determining the planktonic and plant biodiversity, which determines the portability of water and their inter-relationship among zooplanktons and other animals; balances the environmental equilibrium in a lake-ecosystem. The physico-chemical parameters were studied and the result confirms that the soil in the surrounding area of Nakki-Lake can be classified as moderately alkaline soil with (pH 7.11), Average Sand Content (75.12%), Silt Content (11.23%), Clay Content (6.25%), Organic Matter (3.36%), Permeability (27.66 mm/hr), Air Filled Porosity (14.33%) and other parameters showed low mean values including Nitrogen (0.23 mg/L), Phosphorus (52.33 mg/L), Potassium (732.67 mg/L), Magnesium (153.67 mg/L), Chloride (4108.33 mg/L), Sulphur (244.33 mg/L). The soil samples showed an average of Bulk Density (1453 kg/m3), Specific Gravity (2.62), Fusion Point (1245.67 °C), Total Combustible (0.22%), Exchangeable Sodium (0.91%), Calcium Carbonate (1.48%), Effective Temperature of Destruction (971.33 °C), Electrical Conductivity - CaSO4 Extract (2447 μS/cm) while average nitrate and sulphate levels were 31.19 mg/l and 123.73 mg/l respectively. Based on the result of the quality parameters of the soil analysis, the nature of the soil in Nakki Lake and the surrounding area is alkaline.

    Opis:
    Limnological parameter promotes ecological diversity and acts as major key factors of the water body. The portability of water can be determined by planktonic and fish diversity in that water body. Mount Abu (Arbudanchal) is also referred as a place with abode of Gods as it is sated with devotion of all faith. The research site Sant-Sarover Pond has a mythological importance among the localised. In the weather cycle of monsoon (2018), the specific status of limnological characteristic, planktonic diversity and ichthyofauna of Sant-Sarover Pond have been studied through top and bottom water samples. The Limnological parameters of Sant-Sarover Pond showed low mean values including hardness (104.83 mg/l) and TDS (142.0 mg/l)) with optimum alkaline water (pH 7.12), and alkalinity of (98.50 mg/l) Secchi Depth of 80 cm. The average nitrate and sulphate levels were 28.57 mg/l and 122.28 mg/l while average dissolved oxygen levels were at 5.45 mg/l respectively. Based on the results of limnological parameters of water, Sant-Sarover Pond is eutrophic.

    Opis:
    Limnological parameter plays a key role in determining the ecological biodiversity. Planktonic diversity can be considered as a major key factor for determining the portability of water. Nakki Lake has the greatest importance amongst the localised. With a seasonal survey, the specific status of limnological characteristic and planktonic diversity in Nakki Lake have been studied through different weather cycles (2017) across three region based on the geography and in contact with human population over top and bottom water samples. With moderately alkaline water (pH 7.08), alkalinity of (102.16 mg/l) and other limnological parameters showed low mean values including TDS (161.83 mg/l), chloride (109.73 mg/l), and hardness (95.66 mg/l). The average dissolved oxygen levels were at 5.75 mg/l while average nitrate and sulphate levels were 31.19 mg/l and 123.73 mg/l respectively. Based on the results of quality parameters of water and soil, Nakki Lake is eutrophic.

    Opis:
    Study focused on the performance of injection moulded short Wallostonite filler and chopped glass fiber reinforced hybrid epoxy composites. Results showed that hybridization of glass fiber and Wallostonite was found to be comparable to that of epoxy glass fiber composites. Analysis of fiber length distribution in the composite and fracture surface was performed to study fiber breakage fracture mechanism. The simultaneous compounding of epoxy with two fillers was done to obtain a hybrid composite. The mechanical properties of hybrid, injection molded, chopped glass fiber/ Wallostonite/epoxy composites have been investigated by considering the effect of hybridization by these two fillers. This system is expected to have considerable mechanical properties. It has been found that the tensile, flexural, and impact properties of the filled epoxy were higher than those of unfilled epoxy. The hybrid effects of the tensile strength and modulus were studied by the rule of hybrid mixtures (RoHM) using the values of single fiber composites.
