    Opis:
    Mesenteric fibromatosis is a part of the clinical-pathologic spectrum of deep fibromatoses. We report this rare case of primary mesenteric tumor that was diagnosed to be a mesenteric fibromatosis on histopathological examination. In majority of patients it may remain asymptomatic and the management of these tumors depends on histopathological examination. Postoperatively, patient was well and subsequent follow up showed normal recovery.

    Opis:
    The variation of refractive indices with temperature of three pure nematogenic compounds 5OCB, CPHB and 6CHBT were studied experimentally using thin prism technique. The refractive indices $n_{o}$ and $n_{e}$ were measured using 633 nm lines from a He-Ne laser. A modified four-parameter model was taken which is based on the Vuks equation describing the effect of temperature on the refractive indices of liquid crystals. In this paper we report the variation of refractive indices of these three liquid crystals with temperature, using the thin prism method. The variation in birefringence was determined experimentally. The variation in refractive indices and birefringence were also fitted theoretically using the modified Vuks equation. On comparison, the theoretically fitted values show close agreement with the experimental values.

    Opis:
    Purpose: Despite people suffering from several forms of ill health, constant exposure to toxic wastes and chronic diseases as a result of mining, there is a tragic gap in the availability of ‘scientific’ studies and data on the health hazards of mining in India. This study was proposed to understand better the relationship between occupational exposure to coal, blood lipid profiles and red blood cell (RBC) functional status of coal workers. Materials and methods: Blood samples were obtained from coal miners (n=32) of an underground mine in West Bengal. Blood lipid profiles and RBC functional status were determined. Students’ t-test and Pearson correlation analyses were completed to analyze the data. Results: Compared to the control subjects, significantly higher levels of cholesterol (p<0.01), triglycerides (p<0.01), LDL (p<0.001), and VLDL (p<0.001) were observed in coal miners. HDL, Hb, Na+-K+ATPase and SOD activity were significantly (p<0.001) lower in coal miners, whereas MDA levels (p<0.001) and osmotic fragility in coal miners were increased significantly (p<0.01). Conclusions: Our study indicates that elevated MDA and antioxidant insufficiency caused disruption in the structural integrity of erythrocyte, which may be a pathophysiological mechanism in the progression of disease in coal miners. Also, cardiovascular disease risk factors were more prevalent in the coal miners.

    Opis:
    The present study deals to know morphological damages of leaves of four selected plant species near roadside due to vehicular air pollution in Kolkata, India. The selected plant species are Ficus bengalensis, Ficus religiosa, Alstonia scholaris and Neolamarckia cadamba as these are very common as avenue trees. The study area was selected as per Low vehicular load (LVL) as control area, moderate vehicular load (MVL) area, high vehicular load (HVL) area and heavy vehicular load (HeVL) These three sampling stations were selected on the basis of moderate, high and heavy traffic density and continuous vehicular movement as per visualization. The control area was considered as time dependent vehicular movement due to less traffic density. The morphological damages with special reference to length (L), breadth (B) and L/B ratio and visible injuries in leaves. The visible injuries such as pigmentation, chlorosis, necrosis and burning of leaves of four selected species is documented. There was an increasing and decreasing tends in all four plant species at all three vehicular emission exposed sites (MVL, HVL and HeVL) compared to control site (LVL). In all experimental sites such as MVL, HVL and HeVL, the extra growth and reduction pattern significantly (P < 0.001, 0.01 or 0.05) observed when compared to control site (LVL) for L, B and L/B ratio. The visible injuries (in %) of leaves were also observed in increasing trends. This study is a preliminary assessment of tolerant species that already have been used in greenbelt development to protect air pollutants as well as biological monitoring to know exact load of automobile air pollution but further researches are needed in relation to biochemical and genetic damage study. It was observed that out of four selected species Ficus bengalensis, Alstonia scholaris and Neolamarckia cadamba are more tolerant species and Ficus religiosa is a less tolerant species because of these may have fighting abilities by waxy coatings, accumulation and degradation abilities to vehicular air pollution at all exposed area when compared to control area.

    Using the Lie algebraic method, the stretching vibrational energies of fullerenes $C_{70}$ and $C_{80}$ are calculated in the one-dimensional U(2) framework. By constructing the model Hamiltonian with the help of Casimir and Majorana invariant operators in this frame work, we calculated the local mode vibrational energy levels of the fullerenes $C_{70}$ and $C_{80}$.

    Opis:
    In this paper, an attempt has been made to model DPM flow patterns in the vicinity of man riding vehicle(s) operating in a coal mine environment. The DPM flow patterns are modelled using the techniques of computational fluid dynamics (CFD) and validated using field experimental measurements. The models show that if the vehicle is stationary, DPM particles are dispersed towards the center of gallery. Beyond 20m downstream of the vehicle, the DPM particles occupy the entire cross-section of the roadway. If movement of the vehicle is considered, the miners may be exposed to a high concentration of DPM due to the engines running at full capacity and the resultant air flow induced by the movement of the vehicle.

    Opis:
    Objective. We examined the personality correlates of accident-proneness of auto-rickshaw drivers in the Indian city of Ranchi. Methods. This was a cross-sectional study in which 50 male drivers aged 18-50 years, selected randomly from a list of licensed auto-rickshaw drivers in Ranchi, were assessed with a Hindi version of Cattell's 16 Personality Factors (l6-PF) Questionnaire. Results. There was a significantly higher frequency of breaking rules, crossing speed limits, substance use and a trend towards a higher frequency of carrying extra persons (i.e., more than recommended) in accident-prone drivers. There was significant negative correlation of accident-proneness with 16-PF factors such as reasoning, rule consciousness, apprehension and emotional stability. Conclusion. Personality characteristics with lower scores of reasoning, rule consciousness, apprehension and emotional stability are common in commercial auto-rickshaw drivers with high accident-proneness.
