    In this study, the Secondary Treated Waste-Water (STWW) to infiltrate through the soil matrix, hence eliminating the contaminants in the effluent. For this study, three types of soil, such as loamy sand, fine sand, and clayey soil, were subjected to two cycles of wetting and drying to assess the type of soil that removes the maximum contaminants under which cycle. At diverse locations, soil samples were collected and examined to determine the soil types. Likewise, STWW was collected from Chennai Metropolitan Water Supply and Sewerage Board (CMWSSB) and Perungudi Sewage Treatment Plant (PSTP) to illustrate the quality of water before Soil Aquifer Treatment (SAT). About 1.5 m in height and 8 mm in diameter of fabricated acrylic material columns are used for the soil aquifer treatment efficiency studies. Water quality parameters, namely pH, TDS, and turbidity, were monitored throughout the study. All the organic compounds present in water were reduced to a higher level only in the fine sand in the one-day wetting/drying cycle. pH was reduced from 8.55 to 7.5, TDS was reduced from 1580 mg/l to 850 mg/l, and Turbidity was reduced from 7.24 to 4.04 NTU. This proposed method is to minimize the amount of water pollution from the environment. It is an effective way to manage aquifer recharge (MAR). SAT is the easiest method, aquifer and/or soil-based treatment systems improve the effluent quality of wastewater by removing the trace elements in the aquifer during the recharge of groundwater. It is likewise attractive for technologically advanced as well as emerging countries, and it is supple enough to allow adaptation to home-grown requirements by uniting it with predictable natural or bringing about water and technologies of wastewater treatment. Doi: 10.28991/CEJ-2022-08-07-011 Full Text: PD

    The present study were The immune system plays an important role in defense mechanism and protects the body against various antigens and infectious diseases. The homeostatic balance is maintained by the stimulation or suppression of immune cells and it keeps the body in normal healthy condition. Thus, the immune modulator plays a vital role in maintaining the immune system. In this study, the immunomodulatory activity of purified Propolis was studied on cyclophosphamide (CYP) treated immuno-suppressed Swiss albino rats. The immunomodulatory activity of Propolis was compared with standard immune activating drug levamisole. The CYP is an alkylating drug that belongs to the subclass of nitrogen mustard. It is commonly given as a chemotherapeutic drug for cancer treatment and as an immunosuppressant for organ transplantation and autoimmune disorder (Moore 1991)133. CYP also causes some side effects such as myelosuppression, immune suppression and oxidative stress which may be life threatening (Wang et al 2011)134. The inactive form of CYP is activated by the liver enzyme cytochrome P450 to 4- hydroxycyclophosphamide which transferred to other organs as well. Then, 4- hydroxycyclophosphamide is further converted to phosphoramide mustard and acrolein. The phosphoramide mustard causes cytotoxic damage to cells and acrolein causes some side effects (Sun & Peng 2008)135. In this study, CYP is given to the Swiss albino rats to suppress the immune system and induce oxidative stress. The cyclophosphamide effect is expected to reduce the activity of hematological parameters, cell mediated immune responses and macrophage production. Moreover, CYP impaired the organs through its toxic metabolites and caused oxidative stress. The effect of Propolison CYP induced immune-toxicity was examined through myelosuppression, immune suppression and oxidative damage.CONCLUSION: In conclusion, the present study has proved that Propolis not only enhance the immune system but also protect the organs against oxidative stress. The results of the present study recommend that Propolis could be a prominent natural immunomodulating molecule with therapeutic value

    Assessment of groundwater potential using geospatial techniques for urbanized Mambakkam mini-watershed, Kancheepuram district, India

    1856-1865Evaluation of groundwater potential and mapping using geospatial platform is crucial especially for semi-arid hard rock and coastal adjoining terrain to identify the zones of very good, good, moderate and poor groundwater potential. The Mambakkam mini watershed, Tamil Nadu (India) is situated towards the southern part of Chennai city. It is experiencing commercial development of groundwater in addition with escalating domestic and industrial demands. The present study is aimed to develop the mapping of groundwater potential zones for the selected urbanized watershed by using the remote sensing and geospatial techniques. Data like water level, water quality, rainfall, climatology and geophysical resistivity from various sources and satellite imageries have been used for this study to observe the changes on the sources of water resource system. The Inverse Distance Weighted (IDW) method was used for generating the thematic layers of rainfall, depth to bed rock, weathered rock, jointed rock and water levels. The generated village wise groundwater potential map has shown a vast spatial variability of ground water potential and the area that belongs to the “very good” potential category is quite less in the entire study area (12 %) which alarms the development of existing groundwater resource. The study concluded that considerable falling trend of groundwater level during pre-monsoon showing the alarming threat for further development. Thus the presented study identified the risk of groundwater development and provides guidelines to water resource mangers and village officials to recommend conservation and protection strategies against the uncontrolled commercial development especially on the identified poor groundwater potential zones

    Nutritional Supplement of Hatchery Eggshell Membrane Improves Poultry Performance and Provides Resistance against Endotoxin Stress

    <div><p>Eggshells are significant part of hatchery waste which consist of calcium carbonate crust, membranes, and proteins and peptides of embryonic origins along with other entrapped contaminants including microbes. We hypothesized that using this product as a nutritional additive in poultry diet may confer better immunity to the chickens in the paradigm of mammalian milk that enhances immunity. Therefore, we investigated the effect of hatchery eggshell membranes (HESM) as a short term feed supplement on growth performance and immunity of chickens under bacterial lipopolysaccharide (LPS) challenged condition. Three studies were conducted to find the effect of HESM supplement on post hatch chickens. In the first study, the chickens were fed either a control diet or diets containing 0.5% whey protein or HESM as supplement and evaluated at 5 weeks of age using growth, hematology, clinical chemistry, plasma immunoglobulins, and corticosterone as variables. The second and third studies were done to compare the effects of LPS on control and HESM fed birds at 5 weeks of age following at 4 and 24 h of treatment where the HESM was also sterilized with ethanol to deplete bacterial factors. HESM supplement caused weight gain in 2 experiments and decreased blood corticosterone concentrations. While LPS caused a significant loss in body weight at 24 h following its administration, the HESM supplemented birds showed significantly less body weight loss compared with the control fed birds. The WBC, heterophil/lymphocyte ratio, and the levels of IgG were low in chickens fed diets with HESM supplement compared with control diet group. LPS challenge increased the expression of pro-inflammatory cytokine gene IL-6 but the HESM fed birds showed its effect curtailed, also, which also, favored the up-regulation of anti-inflammatory genes compared with control diet fed chickens. Post hatch supplementation of HESM appears to improve performance, modulate immunity, and increase resistance of chickens to endotoxin.</p></div
