Study of Waders Diversity in the catchment area of Ujani Reservoir, Solapur District (MS), India.

The present study was an attempt to access and evaluate the status and distribution of waders associated to wetlands of Ujani Reservoir with special reference to north - west region. Waders are the birds generally observed along shorelines and mudflats that wade in order to forage for food in mud or sand. Ujani wetlands provide feeding and roosting grounds for resident and migratory waders. This study was conducted from December 2015 to November 2017 including seasonal visits to five wetland sites i.e. Kumbhargaon, Diksal, Kondhar-Chincholii, Rajegaon (Bhigwan) and Khanota. During study, about 38 species of waders were identified belonging to 14 families viz. Ardeidae, Charadriidae, Ciconiidae, Jacanidae, Laridae, Rallidae, Motacillidae, Phalacrocoracidae, Phoenicopteridae, Recurvirostridae, Rostratulidae, Scolopacidae, Threskiornithidae and Glariolidae

Inhibition Planktonic and Bio film Growth of Candida Albicans by Plant Extract Alone and in combination with Fluconazole

This study was to evaluate the efficacy of Methanolic extract of G. superba L in combination with Fluconazole against biofilm development and mature biofilms of C. albicans. Synergism between MEGS and Fluconazole combination against biofilm formation was evident with FICI of 0.187. Combination of MEGS and Fluconazole did not have synergistic potential against mature biofilm growth, evidenced in FICI of 0.916. MIC of standard Fluconazole was found to be 0.5 and >0.5 in biofilm development and mature biofilm respectively

Compare Outcomes Of Single Stage Vs Two Stage Urethroplasty For Panurethral Strictures Including Pre-Operative And Post-Operative Course

Aim: The aim of the present study was to compare outcomes of single stage vs two stage urethroplasty for panurethral strictures including pre-operative and post-operative course. Methods: The Observational study was conducted at Dr. D.Y. Patil Medical College and Research Centre, Pimpri for the period of 2 years. The study was conducted in 40 patients randomly dividing into two groups, 20 patients underwent single stage urethroplasty and 20 underwent two staged urethroplasty with or without buccal mucosal graft urethroplasty based on size of urethral plate. Results: In the present study, majority of the patients belonged to 41-50 years age group followed by 31-40 years age group and it was found that age groups were not statistically significant. Majority of the patients had Balanitis xerotica obliterans (LS) etiology followed by Post instrumentation/catheter and the results were not statistically significant. Majority of the patients had 13-15 cms length of stricture. In the present study, 12 and 16 were narrow external uretheral meatus in single and two stage respectively. In the two stage, Johanson’s urethroplasty procedure was done and in single stage, Kulkarni’s full length dorsal onlay BMG urethroplasty procedure was done. In single and two stage, Urethrocutaneous Fistula and Epididymo-orchitis complications were noted. In single stage, success was noted in 16 patients and in two stage, success was noted in 17 patients. Conclusion: The single stage repair in patients with LS had good results with less re-stricture rates. The use of BMG as a substitution in single stage repair had re-stricture rates compared to flaps substitution. The two-stage repair should be limited to complex urethral strictures, failed urethroplasty and obliterated urethral stricture urethral caliber is less than 6F

GW190412: Observation of a Binary-Black-Hole Coalescence with Asymmetric Masses

We report the observation of gravitational waves from a binary-black-hole coalescence during the first two weeks of LIGO’s and Virgo’s third observing run. The signal was recorded on April 12, 2019 at 05∶30∶44 UTC with a network signal-to-noise ratio of 19. The binary is different from observations during the first two observing runs most notably due to its asymmetric masses: a ∼30 M_⊙ black hole merged with a ∼8 M_⊙ black hole companion. The more massive black hole rotated with a dimensionless spin magnitude between 0.22 and 0.60 (90% probability). Asymmetric systems are predicted to emit gravitational waves with stronger contributions from higher multipoles, and indeed we find strong evidence for gravitational radiation beyond the leading quadrupolar order in the observed signal. A suite of tests performed on GW190412 indicates consistency with Einstein’s general theory of relativity. While the mass ratio of this system differs from all previous detections, we show that it is consistent with the population model of stellar binary black holes inferred from the first two observing runs

An integrated bioinformatics analysis reveals divergent evolutionary pattern of oil biosynthesis in high- and low-oil plants

Seed oils provide a renewable source of food, biofuel and industrial raw materials that is important for humans. Although many genes and pathways for acyl-lipid metabolism have been identified, little is known about whether there is a specific mechanism for high-oil content in high-oil plants. Based on the distinct differences in seed oil content between four high-oil dicots (20~50%) and three low-oil grasses (<3%), comparative genome, transcriptome and differential expression analyses were used to investigate this mechanism. Among 4,051 dicot-specific soybean genes identified from 252,443 genes in the seven species, 54 genes were shown to directly participate in acyl-lipid metabolism, and 93 genes were found to be associated with acyl-lipid metabolism. Among the 93 dicot-specific genes, 42 and 27 genes, including CBM20-like SBDs and GPT2, participate in carbohydrate degradation and transport, respectively. 40 genes highly up-regulated during seed oil rapid accumulation period are mainly involved in initial fatty acid synthesis, triacylglyceride assembly and oil-body formation, for example, ACCase, PP, DGAT1, PDAT1, OLEs and STEROs, which were also found to be differentially expressed between high- and low-oil soybean accessions. Phylogenetic analysis revealed distinct differences of oleosin in patterns of gene duplication and loss between high-oil dicots and low-oil grasses. In addition, seed-specific GmGRF5, ABI5 and GmTZF4 were predicted to be candidate regulators in seed oil accumulation. This study facilitates future research on lipid biosynthesis and potential genetic improvement of seed oil content

Properties and Astrophysical Implications of the 150 M_⊙ Binary Black Hole Merger GW190521

The gravitational-wave signal GW190521 is consistent with a binary black hole (BBH) merger source at redshift 0.8 with unusually high component masses, 85⁺²¹₋₁₄ M_⊙ and 66⁺¹⁷₋₁₈ M_⊙, compared to previously reported events, and shows mild evidence for spin-induced orbital precession. The primary falls in the mass gap predicted by (pulsational) pair-instability supernova theory, in the approximate range 65–120 M_⊙. The probability that at least one of the black holes in GW190521 is in that range is 99.0%. The final mass of the merger 142⁺²⁸₋₁₆ M_⊙) classifies it as an intermediate-mass black hole. Under the assumption of a quasi-circular BBH coalescence, we detail the physical properties of GW190521's source binary and its post-merger remnant, including component masses and spin vectors. Three different waveform models, as well as direct comparison to numerical solutions of general relativity, yield consistent estimates of these properties. Tests of strong-field general relativity targeting the merger-ringdown stages of the coalescence indicate consistency of the observed signal with theoretical predictions. We estimate the merger rate of similar systems to be 0.13_(-0.11)^(+0.30) Gpc⁻³ yr⁻¹. We discuss the astrophysical implications of GW190521 for stellar collapse and for the possible formation of black holes in the pair-instability mass gap through various channels: via (multiple) stellar coalescences, or via hierarchical mergers of lower-mass black holes in star clusters or in active galactic nuclei. We find it to be unlikely that GW190521 is a strongly lensed signal of a lower-mass black hole binary merger. We also discuss more exotic possible sources for GW190521, including a highly eccentric black hole binary, or a primordial black hole binary

GW190521 : a binary black hole merger with a total mass of 150 M⊙

On May 21, 2019 at 03:02:29 UTC Advanced LIGO and Advanced Virgo observed a short duration gravitational-wave signal, GW190521, with a three-detector network signal-to-noise ratio of 14.7, and an estimated false-alarm rate of 1 in 4900 yr using a search sensitive to generic transients. If GW190521 is from a quasicircular binary inspiral, then the detected signal is consistent with the merger of two black holes with masses of 85+21−14  M⊙ and 66+17−18  M⊙ (90% credible intervals). We infer that the primary black hole mass lies within the gap produced by (pulsational) pair-instability supernova processes, with only a 0.32% probability of being below 65  M⊙. We calculate the mass of the remnant to be 142+28−16  M⊙, which can be considered an intermediate mass black hole (IMBH). The luminosity distance of the source is 5.3+2.4−2.6  Gpc, corresponding to a redshift of 0.82+0.28−0.34. The inferred rate of mergers similar to GW190521 is 0.13+0.30−0.11  Gpc−3 yr−1
