Description. Head. In full face view, subrectangular with strongly concave occipital margin and weakly convex posterolateral margin (Fig. 2 A). Masticatory margin of mandible with large apical tooth followed by small preapical tooth, robust third tooth, five denticles and a blunt basal tooth (Fig. 3 A). Clypeus with distinctly convex posterior margin, anterior margin nearly straight, anterolateral corners of the median portion of the clypeus with dentiform process (Figs 2 A, 3 A). Antennae 12 segmented with three segmented club; antennal segment II pear-shaped; each segment of III–IX slightly shorter than broad; apical segment (XII) distinctly longer than segments X and XI combined. Scape almost reaching posterolateral corner of head. Eyes very small, 0.05 mm in diameter, located anteriorly at the lateral margin of head at a distance of 0.27 mm from the point of mandibular insertion (Fig. 2 A). Mesosoma. In profile view, dorsal outline weakly convex, sloping backward; anterior ventrolateral corner of pronotum forming a very short tooth like process; mesonotum completely fused with pronotum; mesometapleural suture is feebly visible through the cuticle. Propodeal dorsum weakly demarcated anteriorly; metanotal groove indistinct (Fig. 2 B). In profile view, propodeal dorsum has a small denticle on anterior part; propodeal spines longer than broad at base, curved up apically; propodeal declivity steep and strongly concave (Figs 2 C, 3 C). Metasoma. In dorsal view, petiole longer than broad, almost parallel sides; postpetiole slightly broader than petiole, broader than long, semicircular, weakly concave anterior margin and distinctly convex posterior margin (Fig. 2 B). In profile view, petiole almost as long as high (excluding subpetiolar process); petiolar dorsal surface weakly concave; anterior slope nearly straight; narrow subpetiolar process with relatively broad anterior tip; postpetiole slightly elevated than petiole, almost as long as high (excluding sternopostpetiolar process); sternopostpetiolar process well developed, roundly convex ventral outline, straight anterior margin (Figs 2 C, 3 C). Gaster slightly elongate circular with strongly concave anterior margin (Fig. 3 D). Sculpture: Dorsum of head with distinct rugae, running posterolaterally, interspaces between rugae densely sculptured (Fig. 2 A). Mandible smooth and shiny. Mesosoma dorsally with longitudinal rugae, the rugae running continuously to lateral face (Figs 2 C, 3 B). Petiole and postpetiole dorsally and laterally with longitudinal rugae (Figs 2 C, 3 C). All the legs relatively smooth and shiny. First gastral tergum with micro-punctures (punctulate) anteriorly, coarsely reticulate medially; remaining gastral segments relatively smooth and shiny (Fig. 3 D). Pilosity: Body with abundant long erect hairs. Antenna with abundant suberect and erect hairs. Mandible with numerous thin and long hairs, basal masticatory margin with few spatulate hairs. Anterolateral corner of clypeus with two pairs of relatively large erect hairs and medially with a pair of relatively small erect hairs. All legs with dense suberect to erect hairs. Gaster with abundant erect to suberect hairs. Colour. Dorsum of head, mesosoma and gaster yellow with a dark tinge. All other body parts yellow. Ecology. Two workers of Myrmecina bawai sp. nov. were collected from Phawngpui National Park (Blue Mountain National Park), one specimen each in two pitfall traps 200 m apart. The protected area is named for the mountain Phawngpui, often called the Blue Mountain, which is the highest mountain peak in Mizoram (maximum altitude 2157 m above sea level). The park spreads over an area of 50 km 2 and covers the Blue Mountain along with the surrounding reserve forest. The park consists of sub-tropical broadleaf and tropical evergreen forest. The annual rainfall is approximately 2500 mm and temperature ranges from 2 °C to 30 °C. The type locality is a shaded region with about 70% canopy cover. Etymology: As Ashoka Trust for Research in Ecology and the Environment (ATREE) is celebrating its 25 th anniversary in 2021, this species is named in honour of its founder president Prof. Kamaljit S. Bawa, renowned evolutionary ecologist and conservation biologist. Identification. Myrmecina bawai sp. nov. is close to Myrmecina taiwana Terayama, 1985 in body colour, relatively small eyes, absence of tooth like process on the middle anterior clypeal margin and presence of anterior pair of denticles on the propodeal dorsum. However it differs from M. taiwana by the following characteristics: 1) head and mesosoma with distinct rugae, the interspaces between rugae densely punctate in M. bawai (head and mesosoma with longitudinal rugose sculpture in M. taiwana); 2) a dentiform process is present on anterolateral corners of the middle portion of the clypeus in M. bawai (dentiform process on anterolateral corner of the middle portion of the clypeus absent in M. taiwana); 3) first gastral tergum punctulate anteriorly, coarsely reticulate medially in M. bawai (gaster smooth in M. taiwana); 4) large size, HW 0.80, TL 3.73 in M. bawai (small size HW 0.59—0.61, TL 2.62—2.73 in M. taiwana).Published as part of Aswaj, Punnath, Anoop, Karunakaran & Priyadarsanan, Dharma Rajan, 2021, Description of two new species of ants of the genus Myrmecina Curtis, 1829 (Hymenoptera: Formicidae: Myrmicinae) from the Eastern Himalayas, pp. 160-171 in Zootaxa 4990 (1) on pages 163-166, DOI: 10.11646/zootaxa.4990.1.10, http://zenodo.org/record/498257

Nano-machining of biosensor electrodes through gold nanoparticles deposition produced by femtosecond laser ablation
No full textWe report an application of femtosecond laser ablation to improve the sensitivity of biosensors based on a quartz crystal microbalance device. The nanoparticles produced by irradiating a gold target with 527-nm, 300-fs laser pulses, in high vacuum, are directly deposited on the quartz crystal microbalance electrode. Different gold electrodes are fabricated by varying the deposition time, thus addressing how the nanoparticles surface coverage influences the sensor response. The modified biosensor is tested by weighting immobilized IgG antibody from goat and its analyte (IgG from mouse), and the results are compared with a standard electrode. A substantial increase of biosensor sensitivity is achieved, thus demonstrating that femtosecond laser ablation and deposition is a viable physical method to improve the biosensor sensitivity by means of nanostructured electrodes

The current dissertation proposes four theoretically-relevant moderators expected to enhance the Agreeableness leadership advantage: (a) collectivism, (b) in-person (vs. remote) work, (c) leader gender, and (d) follower agreeableness. The Agreeableness leadership advantage is theoretically considered by leveraging insights from Trait Activation Theory, Media Richness Theory, Role Congruity Theory, and the Interpersonal Complementarity Hypothesis. In general, this dissertation examines the question “when does Agreeableness positively predict leadership effectiveness?” (hypothesizing a stronger relationship under high collectivism, in-person work, a female leader, and an agreeable follower). Initial evidence from the current study offers some support for the first three moderators (all except follower Agreeableness), although the plotted interaction effects suggest that these factors affect disagreeableness leadership disadvantage (i.e., pinpointing circumstances where disagreeableness is more costly), rather than Agreeableness leadership advantage per se. Implications for theory and practice are discussed

No full textSerum Free Light Chain Assay as a Prognostic Marker in Patients with Aggressive B-Cell Non-Hodgkin's Lymphoma: Impact on Survival Outcome
No full textAbstract
T.M. Anoop
Background The role of serum free light chain (FLC) as a prognostic biomarker in lymphoproliferative diseases is being increasingly studied. In this study we present the 5-year survival outcome for patients with aggressive B-cell non-Hodgkin's lymphoma (NHL) and their relation to FLC and other known prognostic markers.
Materials and Methods This is a prospective study conducted in patients diagnosed with aggressive B-cell NHL. Serum FLC level and ratio were estimated prior to initiation of treatment.
Results A total of 100 patients were included in the study from December 2013 to December 2015 with a median age of 53 years. Thirty-eight patients (38%) had elevated FLC level of which 26% were polyclonal and 12% were monoclonal elevations. Abnormal FLC ratio was noted in 12% patients. Median follow-up duration of the study was 75 months. Five-year relapse-free survival (RFS) for the study population was 54.4%. Five-year RFS was 64.1% for early stage and 48.2% for advanced stage diseases (p = 0.05). The RFS was significantly better in age less than 60 years (59.5% vs 43.8%, p < 0.001). Five-year overall survival (OS) was 61.3%. OS was significantly better in younger patients (73.6% vs 33.4%, p < 0.001), with International Prognosis Index score of 0 to 2 (87.4% vs 26.7%, p < 0.001). Patients with elevated FLC had inferior RFS (50% vs 71.4%, p = 0.04). Abnormal FLC ratio also strongly corresponded to inferior RFS (54.5% vs 66.2%, p = 0.001). OS was also significantly inferior in patients with abnormal FLC ratio (72.6% vs 63.6%, p = 0.001).
Conclusion In patients with newly diagnosed aggressive B-cell NHL, elevated FLC levels and abnormal FLC ratio were significantly associated with inferior survival
Combined effects of enhanced ultraviolet-B radiation and mineral nutrients on growth, biomass accumulation and yield characteristics of two cultivars of vigna radiate L
No full textAbstract: In a field experiment, the effect of enhanced UV-B radiation (simulating 20% ozone depletion at Allahabad, 20 0 47' N latitude) was studied on two cultivars of Vigna radiata L. with various levels of mineral nutrients (N and P). Study showed decrease in total biomass accumulation, harvest index, RSR and yield after exposure with enhanced level of UV-B. RGR and CGR also showed decline after exposure with UV-B. Application of recommended dose of mineral nutrients alleviated the deleterious effect of UV-B and increased plant dry matter vis a vis yield. Both cultivars showed sensitivity to UV-B but cultivar Malviya Janpriya was more responsive to UV-B than Malviya Jyoti
