    The Silent Spring by Rachel Carson, which brought the issue of pesticides to the center stage is dedicated to Albert Schweitzer, who said, “Man has lost the capacity to foresee and to forestall. He will end by destroying the Earth”. This paper will try to understand and analyse our position with regard to the prediction made by Albert Schweitzer. Are we still moving in the same direction of self-destruction or have we regained our capacity to foresee and forestall? Man’s interaction with nature has altered it in very significant ways which in turn has been affecting the life of man in unpredictable ways.  The way forward is from adverse Anthropocene to conscious Anthropocene. Shankar’s 2018 release, Akshay Kumar and Rajnikanth starrer 2.0 warn us about the problems of radiation which will wipe away the birds from Earth before us going the same way. How the overcrowded telephone network towers and the radiation from them will wreak havoc, if not checked right away is the point of discussion in the movie. 2016 release Remo D’ Souza’s A flying Jatt, starring Tiger Shroff also speaks of the impending doom if we do not manage our waste properly. The pollutants which we are releasing generously into the environment are nothing but our own suicide in installments. The writing has been on the wall for long. Poornachandra Tejaswi in his novel Chidambara Rahasya depicts the picture of a society which ignores this writing on the wall for short term gains and this shortsightedness results in the destruction of nature, culture and the life as we know. This paper intends to study the equation between man and nature as depicted in the above mentioned movies and literature

    Active vibration control of structures has gained a lot of interest in recent years. This paper presents an active vibration control methodology of a structure using piezoelectric actuators. The proposed methodology is useful in practical applications where the system to be controlled is difficult to model due to the presence of complex boundary conditions. The impedance matching control technique uses a power flow approach wherein the controller is designed such that the power flow into the structure is minimized. The system transfer function is obtained from the experimental collocated actuator/sensor pair data using Eigen Realisation Algorithm (ERA). The controller is designed for the system transfer function according to impedance matching theory. The above approach is targeted towards the vibration control of wind tunnel stings, which suffer from flow-induced vibration. A wind tunnel sting model is designed and fabricated for this study. The real time implementation of the impedance matching controller has been carried out using dSPACE® Digital Signal Processor (DSP) card. The results are encouraging and demonstrate the feasibility of applying this technique in the wind tunne

    STATEMENT OF THE PROBLEM: Breast feeding is an essential for survival, physical growth, mental development, performance, productivity, health and well-being across the entire life-span to human beings. NEED FOR STUDY: Breast milk is the nature’s most precious gift to the newborn. LSCS is done to preserve the life and health of the mother and fetus. Especially primipara mothers undergone LSCS suffer from breast complications and reluctant to continue breast feeding. This leads them to go for alternative choices of other feedings to the neonates. That results in failure in effective breast feeding. The researcher while providing care to the mother and their newborn in the post-operative ward, seen mothers suffer from breast complications like breast engorgement, inverted nipples, sore nipples and mastits. The simple nursing intervention like educating the mother on prevention and management of selected breast complications would be supporting in the initial. This initiated the researcher to study the effectiveness of educating mothers on prevention and management of selected breast complications. OBJECTIVES: 1. To assess the pretest level of knowledge regarding prevention and management of selected breast complications among LSCS primipara mothers in experimental and control group. 2. To evaluate the effectiveness of structured teaching programme regarding prevention and management of selected breast complications among LSCS primipara mothers in experimental group. 3. To compare the pretest and post-test level of knowledge regarding prevention and management of breast complications among LSCS primipaara mothers in experimental and control group. 4. To find out the association between the post test knowledge scores with selected socio-demographic variables of LSCS primi mothers in experimental and control group. RESEARCH METHODOLOGY: • Research approach - Quantitative research approach. • Duration of the Study - Four Weeks (20.11.2016 to 18.12.2016). • Study Setting - Post-operative ward at IOG. • Study design - Quasi-Experimental (pretest-post test) design. • Study Population - LSCS primipara mothers. • Sample Size - 60 LSCS Primipara mothers. • Sampling technique - Convenient Sampling Technique. DATA COLLECTION PROCEDURE: After obtaining informed and written consent approximately three to five samples were selected every day and pretest questionnaire was given to them and collected after its completion. Structured teaching programme was given to the participants for 30 minutes. After pretest, post test was conducted after 1 week to assess the knowledge of women regarding prevention and management of selected breast complications. DATA ANALYSIS: Demographic variables in categorical/dichotomous were given in frequencies with their percentages. knowledge score was given in mean and standard deviation. Difference between experiment and control was analysed using student independent t-test. Difference between pretest and posttest was analysed using student paired t-test. Qualitative data t pretest and posttest was analysed using Extended McNemar’s chi square test. Similarity of demographic variables between experiment and control was calculated using chi square test for independence. Differences between experiment and control score was analyzed using percentage with 95% CI and mean difference with 95% CI. Association between level of knowledge gain score with demographic variables are analysed using oneway analysis of variance F-test and independent t-test. P<0.05 was considered statistically significant. RESULTS: The findings of the study revealed that the structured teaching programme had improved the knowledge of LSCS primipara mothers regarding prevention and management of selected breast complications with paired t –test P value is 0.001. There is statistical significance in knowledge attainment on prevention and management of selected breast complications among LSCS primipara mothers. DISCUSSION: Hypothesis was proved by the great statistically significance occurs after STP. The chi square test shows that there is no association between the post test level of knowledge and demographic variables among women. RECOMMENDATION: 1. A comparative study can be conducted between the knowledge of the mothers in prevention of breast complications and their practices. 2. A follow up study can be recorded to determine the participation in practice for the prevention and management of selected breast complications. CONCLUSION: The result of the study shows that STP was effective in prevention and management of selected breast complications among LSCS primipara mothers

    Seeds of Macrotyloma uniflorum were fed with various concentrations of PEG ranging from 5 to 25% during germination and continued till 45 days after germination on alternate days to induce water stress. Inoculums of Glomus mosseae and G. fasciculalum were added to the soil in pot experiment before sowing the seeds. Nodule number, mass, leghaemoglobin and proline contents were estimated in 45 days old plants of unstressed, induced stressed, unstressed AMF treated and stressed AM fungal treated. Observations revealed that AM fungal association improves the number and mass of nodules along with enhanced contents of leghaemoglobin under induced stressed condition. Content of proline in leaves is increased under induced stress in both mycorrhizal and non mycorrhizal plants. However the increase is more evident in non mycorrhizal plants than AM fungal treated plants under induced stress indicating better osmotic adjustment by AM symbiosis. Among the two AM fungal species, G. mosseae is more compatible with the host by improving all the parameters studied than G. fasciculalum inoculated plants indicating its host specificity. The significance of AM fungal association in the process of nodulation of legumes is discussed

    Background: Premature rupture of the membranes at term is spontaneous rupture of the membranes after 37 weeks of gestation and before the onset of the regular painful uterine contractions, complicates 5-10% of pregnancies, 80% of cases of PROM occur at term. It complicates the pregnancy leading to maternal and fetal complications, immediate risks such as cord prolapse, cord compression and placental abruptions, and later risks such as maternal or neonatal infection and the interventions such as caesarean section and instrumental vaginal delivery. These cases are either managed conservatively or by immediate induction of labour. Objective of present study is to compare the efficacy and safety of induction of labor versus expectant management at term PROM, in terms of maternal and fetal outcome.Methods: A randomized control trial of 100 women coming to KIMSH from 01 /04 /2015 to 01 /05 /2016 with PROM at term with duration of leak ≤6 hours and a Bishop score ≤5 were assigned to group A immediate induction group and group B expectant management group with 50 cases in each group.Results: The mean interval from PROM to delivery was significantly shorter in the induction Group 15.62±4.97 as compared with expectant group 17.58±4.78. Incidence of maternal morbidity and neonatal morbidity was comparable in both the groups. Intrapartum complications and mode of delivery were similar in both groups.Conclusions: Immediate induction of labour in cases of PROM at term using oral misoprostol resulted in shorter induction delivery interval and hospital stay. Maternal morbidity and neonatal morbidity was comparable in both groups. It is concluded that immediate induction is better than expectant management. With active management many patients delivered vaginally within 24 hours without increase in the Caesarean section rate and decreased the need for oxytocin augmentation
