ProB: A Model Checker for B
No full textWe present ProB, an animation and model checking tool for the B method. ProB's animation facilities allow users to gain confidence in their specifications, and unlike the animator provided by the B-Toolkit, the user does not have to guess the right values for the operation arguments or choice variables. ProB contains a model checker and a constraint-based checker, both of which can be used to detect various errors in B specifications. We present our first experiences in using ProB on several case studies, highlighting that ProB enables users to uncover errors that are not easily discovered by existing tools

Telangana: Nagarkurnool district, Amrabad Tiger Reserve, Way to Dharavagu, Kollam penta beat, 600 m, 14 August 2020, A . Ramakrishna & B. Sadasivaiah 2217 (holotype: CAL; isotypes: HY, TBGH, BSID). Diagnosis:— Euphorbia telanganensis is morphologically similar to E. jodhpurensis, but differs in having obovate or elliptic-obovate or ovate-elliptic, and abaxially pubescent leaves (vs. oblong to obliquely oblong or oblong to linearoblong, glabrous), 1.5–2.2 mm long peduncle (vs. c. 1 mm long), turbinate involucre (vs. campanulate), ellipsoid glands (vs. rounded), ellipsoid and unequal limb of glands (vs. orbicular and equal), posterior two limbs are shallowly undulate (vs. margins entire), deeply keeled and trigonous capsules (vs. shallowly keeled and subglobose). Description:— Erect annual herb, 30–40 cm tall; latex milky. Stem sympodial, dichotomously branched; branches terete, distally filiform, glabrous, pale green; internodes 2–4 cm long, thickened at nodes; stipules triangular, laciniate, less than 1 mm long.

Habitat:— Euphorbia telanganensis is found growing in blackish-red soils of dry deciduous forest at an elevation range of 500– 750m.The common associates are Crotalaria medicaginea Lamarck(1786:201), Curcuma pseudomontana Graham (1839: 210), Cymbopogon coloratus (Hooker 1896: 206) Stapf (1906: 321), Eleiotis monophylla Candolle (1825: 348), Heteropogon contortus (Linnaeus 1753: 1045) Palisot de Beauvois (1817: 836), Rhynchosia suaveolens (Linnaeus 1781: 326) Candolle (1825: 387) Distribution:— Apparently endemic to Amrabad Tiger Reserve (Type locality), Telangana, India. Etymology:— The specific epithet refers to the state (Telangana state) of its occurrence. Additional specimens examined:— INDIA. Telangana: Nagarkurnool district, Amrabad Tiger Reserve, Way to Dharavagu, Kollam penta beat, 600 m, 20 August 2020, A . Ramakrishna & B. Sadasivaiah 2225 (paratype: TBGH!); Rasamolabavi, 730 m, 10 October 2021, K . Prasad & B. Sadasivaiah 2298 (paratype: BSID!, TBGH!). Conservation status:— In the present floristic survey we have noticed more than 400 individuals at two localities in the Amrabad Tiger Reserve and further explorations in the adjacent areas are required. Presently, the area is well protected as it falls under the Amrabad Tiger Reserve. Therefore, there is no immediate threat to this species but the habitat is prone to forest fires and grazing. Following the IUCN guidelines version 14 (IUCN, 2019), Euphorbia telanganensis is assessed as Data Deficient (DD). Note:— The new species, Euphorbia telanganensis and its closely allied species E. jodhpurensis display common morphological characters like small erect herbs, stem dichotomously branched, stipules interpetiolar and laciniate, leaves on main stem distinctly or slightly larger than the leaves on branches, base oblique, dark green on adaxial and silvery green on abaxial surface, presence of petaloid appendages and ecarunculate seeds. It is differing from E. jodhpurensis in having obovate or elliptic-obovate or ovate-elliptic, and abaxially pubescent leaves, 1.5–2.2 mm long peduncle, turbinate involucre, ellipsoid glands, ellipsoid and unequal limb of glands, posterior two limbs are shallowly undulate, deeply keeled, and trigonous capsules. However, another endemic species of Peninsular India, namely, E. erythroclada Boissier (1862: 25) show most congruence with E. telanganensis but differs in having main stem leaves are distinctly or slightly larger than those on branches (vs. main stem and branches of leaves almost equal), leaves pubescent on abaxial (vs. glabrous), involucre 1–1.3 mm long (vs. more than 1.5 mm long), limb of glands unequal, ellipsoid (vs. equal, oblong), posterior two limbs are shallowly undulate (vs. perfectly wavy), capsules deeply keeled and glabrous (vs. shallowly keeled and sparsely hairy). However, two more related species [E. clarkeana Hooker (1887: 253) and E. granulata Forsskål (1775: 94)] were display common key character as leaves of main stems distinctly larger than those on branches, but these species were found to have their own diagnostic features and are clearly distinct from E. telanganensis. Euphorbia clarkeana has prostrate or decumbent habit, stems sparsely hairy, leaves oblong, glabrous, involucre campanulate, limbs of glands minute and as long as glands, capsules obtusely keeled and E. granulata has prostrate habit and covered with densely hispid-villous hairy, leaves ovate-oblong or subobovate, with entire margins, involucre covered with white pilose, ovary hirsute, capsules obtusely keeled and coarsely villous.Published as part of Sadasivaiah, B., Ramakrishna, A., Prasad, K., Devi, N.

Ag doped Sn3O4 nanostructure and immobilized on hyperbranched polypyrrole for visible light sensitized photocatalytic, antibacterial agent and microbial detection process
No full textAg doped Sn3O4 Nanostructure and immobilized on hyperbranched polypyrrole is investigated in this project. The product was synthesized by the hydrothermal synthesis method. The surface and structural characteristics of the product was studied by different instrumental analysis. The fabricated nanocomposites was utilized as a nano photocatalyst in the removal of methylene blue dye. The crystallography results depicts the triclinic phase of Sn3O4 with the crystallite size 36.3 nm. The band gap of the Ag-Sn3O4/hyperbranched polypyrrole was found 1.50 eV from kubelka-munk measurements. The specific surface area was increased in the presence of the hyperbranched polypyrrole as compared to Ag-Sn3O4 samples. The photo-catalytic activity of composites was found 100.0% degradation of CR in 30 min under visible light irradiation. The catalytic kinetic was followed from the first kinetic model. Moreover, the Ag/Sn3O4/hyperbranched polypyrrole was applied as a bactericidal agent against Streptococcus pneumoniae, and Pseudomonas aeruginosa bacteria. Determination of Streptococcus pyogenes as a pathogenic bacteria was investigated by using aptamer/Ag/Sn3O4/hyperbranched polypyrrole in peroxidase activity. The detection limit of S. pyogenes was 71.0 CFU/mL by using the nano-aptamer
