The Perceived Impact of Parental Depression on the Narrative Construction of Personal Identity: Reflections from Emerging Adults

This paper presents a narrative analysis of emerging adults’ perceptions of the impact of parental depression on themselves as they reflected back on their lives in their natal home. Archived interview narratives were analyzed from sixteen respondents from a preventive intervention study of depression in families. The perceptions of parental depression and the perceived impact of parental depression were found to fall into five perspectives: resistance (no impact), negativity (being disadvantaged), ambivalent perspectives (disadvantaged but also sensitized), acceptance (reconciling with loss), and, compassion (sensitivity and caregiving). The findings from the narratives indicated that the perceived impacts of parental depression spanned a spectrum of responses, not all of which were negative. Emerging adults with their own history of depression reported a more resistant or negative perceived impact of parental depression, and more boys than girls narrated perceived negative impacts of parental depression on the self. These perspectives on parental depression derived from the narratives offer clinicians and family therapists a means of understanding the impact of depression on emerging adults’ sense of self. Implications of language usage, such as tense and coherence, are also discussed

POTENTIAL ANTI-TUMOR AND ANTI-INFLAMMATORY ACTIVITY OF SIX MISTLETOE PLANTS IN THE FAMILY VISCACEAE PRESENT IN WESTERN GHATS, INDIA

ABSTRACTObjectivesTo find out the cytotoxicity, anti-tumor and anti-inflammatory activities of six species of plants belongs to Viscaeceae family available in Western Ghats (India).MethodsIn vitro cytotoxicity of Viscum extracts was studied by trypan blue exclusion method and MTT assay using various cell lines. Anti-tumor activity was determined using Ehrlich ascites carcinoma (EAC) and Dalton's lymphoma ascites (DLA) cells in mice. Anti-inflammatory activities of Viscum extracts were studied using carrageenan and dextran induced mouse paw edema models in mice.ResultsAll six Viscaeceae plant extracts studied were cytotoxic towards transformed cell lines like DLA and EAC as well as to MCF-7, MDA-MB-231 and SKBR3 cell lines. V.orientale, V.nepalense and V.ramosissimum, V.trilobatum were cytotoxic towards normal cells while V.angulatum and V.capitellatum were found to be nontoxic. Excepting V.angulatum all the other species selected here showed toxicity to animals. Administration of nontoxic concentration of extracts of Viscaeceae plants significantly (P<0.001) increased the lifespan of ascites tumor bearing animals and reduced DLA cells induced solid tumor development. All these plants except V.capitallatum and V.trilobatum showed significant (P<0.001) anti-inflammatory activity against carrageenan and dextran models and reduced pro-inflammatory cytokine levels.ConclusionOut of six species studied four species of Viscum species studied were cytotoxic to tumour cells and inhibited tumour development. Of the six species studied V. angulatum was non-toxic to animals and showed maximum efficiency as an antitumour agent. These plants showed significant anti-inflammatory activity and reduced inflammatory markers

Estimation Methods for Determination of Drag Characteristics of Fly-by-Wire Aircraft

"In this paper, several parameter/state estimation approaches for the determination of drag polars from flight data are described and evaluated for a fly-by-wire (FBW) aircraft. Both model-based approaches (MBAs) and non-model-based approaches (NMBAs) are considered. Dynamic response data from roller coaster and wind- up-turn manoeuvres are generated in a FBW aircraft flight simulator at different flight conditions and the typical performance results are presented. A novel approach to estimate the drag polar has been evaluated. It has been found that the NMBAs perform better than the MBAs. Classically, the MBAs have been used for the determination of drag polars. The merits of an NMBA are that it does not require specification of the detailed model of the aerodynamic coefficients and it can be suitably used for online estimation of drag polars from the flight data of aerospace vehicle

SYNTHESIS, CHARACTERISATION AND APPLICATION OF PHENOL-FORMALDEHYDE RESIN BLENDED WITH SULPHONATED PHYLLANTHUS EMBLICA, LINN., CARBON

Phenol – Formaldehyde Resin (PFR) is blended with Sulphonated Phyllanthus emblica, Linn., Carbon (SPEC) in various proportions by weight percentage (0-50%w/w). A few composite cation-exchangers were prepared by varying the amount of SPEC (a source of cheap and renevable plant material) in the blends from 10 to 50% (w/w). Reaction conditions for the preparation of blends were optimised. IR spectra, TGA traces, and SEM photos were taken for the characterization of  resins. Physico-chemical, properties of the composite resins have been determined. The composites are insoluble in various solvents and reagents and stable towards heat.   Cation exchange capacity (CEC) of the composite resins, decreased with the increasing percentage of SPEC in the blend. Thermodynamic equilibrium constants (lnK) are calculated for H+ - Zn2+ exchanges on the resins having a different amount of SPEC. Thermodynamic parameters are also calculated and suitable explanations are given. The composites up to 20% (w/w) blending retains all the essential properties of the original PFR, since the Phyllanthus emblica, Linn., is the low cost, freely available plant material. Therefore, the composites could be used as low cost ion-exchangers, when SPEC partly replaces the original PFR up to 20% (w/w) blending without affecting the properties of PFR

Utilization pattern of antenatal health care services among married women of reproductive age group in the rural area of Surendranagar district, Gujarat, India: a community based cross sectional study

Background: Maternal mortality continues to be a major public health problem. Inspite of the existence of national programmes for improving maternal and child health in India, maternal mortality and morbidity continue to be high. High quality antenatal care is the most important way to reduce the maternal morbidity and mortality. Utilization of Ante natal care (ANC) services is poor in the rural areas, causing significant impact on the health of the mother and ultimately leads to increased maternal morbidity and mortality.Methods: It was a Community based Cross-sectional study. The study was carried out through oral questionnaire method using pre-designed and pretested performa. All the information was collected, compiled and analysed by applying suitable tests. The data was analysed by Statistical Package for Social Sciences (SPSS) and Microsoft word and Excel have been used to generate graphs, tables etc.Results: A total of 403 women were included in the study. Pregnancy registration was done by 88.77% of the women at either government facility or private doctor. Out of total registered women, majority i.e. 54.25% had registered their pregnancy during 2nd trimester. In response to frequency of antenatal visits, study showed that, 59.18% (216) women had availed three or more than three antenatal visits. It was found that 81.92% (299) had taken complete (2 doses) tetanus immunization. About 47% of women had completed full course of iron and folic acid tablets. It was observed that only 46.03% women had availed complete ANC package.Conclusions: Although Antenatal services in India have been created, strengthened and expanded over the years, their output in terms of utilization particularly in rural area is still limited. The present study has brought out many significant socio cultural barriers like caste, women’s literacy, husband’s literacy, occupation of women, socio-economic class and parity of women affecting the utilization of services

Aluminium metal matrix composites: A retrospective investigation

Aluminium matrix composites (AMMCs) are considered to be new generation potential materials for many engineering applications. Different kinds of reinforcement have been infused into the aluminium matrix in order to improve hardness, toughness, stiffness, wear resistance, fatigue properties, electrical properties and thermal stability as compared to their conventional unreinforced counterparts. The characteristics of AMMCs depend largely upon the type of reinforcement materials, interface bonding and processing parameters. In this article we have attempted to investigate the development of aluminium metal matrix composites (AMMCs) along with associated challenges and significant application areas
