Xanthopimpla barodaensis spec. nov. (Hymenoptera: Ichneumonidae).

Eine ockerfarbene Art mit schwärzlicher Färbung der hinteren ersten Trochantern und der Basis der hinteren Tibien; Mesonotum, Propodaeum und Unterleib mit schwärzlichen Flecken; Propodaeum zellig, Areole sechseckig; das Zentrum der basalen Rückenplatte des Unterleibs mit zwei sehr nahe beieinanderliegenden schwärzlichen Flecken und zwei fast runden schwärzlichen Flecken an jeder Seite der Tergiten von der zweiten bis zur siebenten. Flügel ohne kleine Areole, schwärzlicher Fleck an der Wurzelbasis, das Längenverhältnis zwischen der zweiten rückläufigen Ader und der Radialader von ihrer Verbindung bis zur Basis des Radius des Hinterflügels 0,55. Bei sehr wenigen Arten von Xanthopimpla Saussure fehlt die kleine Areola wie bei Xanthopimpla barodaensis spec. nov. Daher ist Xanthopimpla naenia Morley der nächste Verwandte dieser neuen Art.Nomenklatorische Handlungenbarodaensis Lal, 1968 (Xanthopimpla), spec. n.An ochraceous species with hind first trochanters and base of hind tibiae nigrescent; mesonotum, propodaeum and abdomen with nigrescent spots; propodaeum areated, areola hexagonal; the centre of basal tergite of abdomen with two nigrescent spots very near each other and two nearly round nigrescent spots on each side of the tergites from second to seventh. Wings without areolet, nigrescent spot at the base of the radix, the ratio of the length between second recurrent nervure and radial nervure from their junction to the base of the radius of the hind wing 0.55. - Very few species of Xanthopimpla Saussure lack areolet as does Xanthopimpla barodaensis spec. nov. Thus the nearest relative of this new species is Xanthopimpla naenia Morley.Nomenclatural Actsbarodaensis Lal, 1968 (Xanthopimpla), spec. n

Intuitive evaluation of contemporary management strategies in thymoma — the largest Indian experience

Background: The aim was perusal of the treatment strategies, clinical outcomes and factors impacting these outcomes in thymoma. Materials and methods: A total of 119 patients diagnosed and treated cases of thymoma, at our hospital, were taken for analysis. Thirty-one patients were excluded due to inadequate medical records. Descriptive statistics were used to report demographic and clinical characteristics. Time period between diagnosis and death was defined as overall survival (OS). Multivariate analysis (MVA), using cox regression modelling, was done by including clinicopathological factors in a bid to identify prognostic factors influencing OS. SPSS version 26 was used for statistical analysis. Results: The mean age of the patients was 52.17 years and 39 (44.3%), 19 (21.6%), 17 (1.3%) and 13 (4.8%) patients presented with Masaoka stage II, IV, III and I, respectively. Surgery was done in 64 (72.7%) of the patients as a part of the treatment strategy. Radiotherapy was administered to a total of 57 patients with a median dose of 50.4 Gy. Early Masaoka stage at presentation and use of surgery in the treatment plan were statistically significant prognostic factors for a better overall survival on multivariate analysis. Conclusion: Judicious use of radiotherapy and chemotherapy in locally advanced cases may render them resectable. In a bid to gain good survival rates, aggressive multimodality treatment should be offered to the patients

Combined Experimental and CFD Investigation of the Parabolic Shaped Solar Collector Utilizing Nanofluid (CuO-H2O and SiO2-H2O) as a Working Fluid

Nanoscience application plays a major role in heat transfer related problems. A nanofluid is basically a suspension of fine sized nanomaterials in base fluids like water, Therminol VP-1, ethylene glycol, and other heat transfer fluids. This paper evaluates the possible application of nanofluid in parabolic shaped concentrating solar collector using both experimental and CFD analysis. Different types of nanomaterials used are SiO2 and CuO of 20 nm average size. Nanofluids of SiO2-H2O (DI) and CuO-H2O (DI) of 0.01% volume concentration are used. Flow rates of 40 LPH and 80 LPH are used. ANSYS FLUENT 14.5 is used for carrying out CFD investigation. 3D temperature distribution of absorber tube is obtained using numerical investigation and the result is compared with the experimental one. Improvement in efficiency of collector of about 6.68% and 7.64% is obtained using 0.01% vol. conc. SiO2-H2O (DI) nanofluid and 0.01% vol. conc. CuO-H2O (DI) nanofluid, respectively, as compared to H2O (DI) at 40 LPH while at 80 LPH improvement in efficiency of collector of about 7.15% and 8.42% is obtained using 0.01% vol. conc. SiO2-H2O (DI) nanofluid and 0.01% vol. conc. CuO-H2O (DI) nanofluid, respectively, as compared to H2O (DI). Both experimental and CFD temperature results are in good agreement
