Nutrient management for jute-rice cropping system using soil test target yield equation

A field experiment was conducted during the year 2011-13 to study the nutrient management based on soil test to achieve the target yield of jute and rice and their effect of soil nutrient status for jute-rice cropping system. The target yield of jute fibre (3.5 t/ha) with -6% deviation and target yield of rice (5.5 t/ha) were achieved with application of 100% NPK based on ST-TY based along with 5 t/ha Farm Yard Manure (FYM). The highest system productivity (11.7 t/ha) and benefit-cost ratio (3.16) was also recorded higher with application 100% NPK based on ST-TY based along with 5 t/ha FYM. The nutrient uptake by crops and soil nutrients status were higher after three year of jute-rice cropping sequence when NPK were applied with FYM. Hence, combination of inorganic and organic (FYM) fertilizer could achieve target yield and maintain the soil fertility status

Effect of Speed Agility Quickness and Circuit Training on Lipid Profile of Soccer Players: An Observational Study

Study purpose. This observational study aims to investigate the impact of a Speed Agility Quickness (SAQ) and Circuit training program on the lipid profile of soccer players. The study focuses on analyzing changes in high-density lipoprotein (HDL), low-density lipoprotein (LDL), and very-low-density lipoprotein (VLDL) cholesterol concentrations after the intervention. Materials and methods. The study involved a total of 30 elite soccer players with the mean (Sd) of age 16.93 (1.20) years; stature 5.66 (0.16) feet; weight 59.93 (5.47) kg. All the players selected for the study were registered players of Poloi Academy, Imphal, Manipur. The participants were divided into two groups, i.e., the SAQ and Circuit groups, and underwent a 12 weeks SAQ and Circuit training program respectively, which was conducted 3 days per weeks. Blood samples were collected before and after the intervention to measure HDL, LDL, and VLDL cholesterol levels. The participants’ lipid profiles were assessed using standard laboratory techniques. Results. The results of this study demonstrated significant changes in the lipid profiles of the elite soccer players following the SAQ and Circuit training program. The intervention resulted in a significant increase in HDL cholesterol levels. Simultaneously, there was a substantial decrease in LDL and VLDL cholesterol concentrations. Conclusions. The increase in HDL cholesterol and reduction in LDL and VLDL cholesterol levels indicate a potential decrease in the risk of cardiovascular diseases and related health issues. Considering the importance of lipid metabolism in athletic performance and overall well-being, this study provides valuable insights for coaches, athletes, and sports professionals in designing targeted training regimens to optimize cardiovascular health among soccer players. However, further research with larger sample sizes and long-term follow-ups is warranted to validate and generalize these findings across diverse populations and sports disciplines

Effect of irrigation and nutrient management on growth, fibre yield and water use of ramie (Boehmeria nivea)

The experiment was conducted at Research Farm of CRIJAF, Barrackpore, Kolkata during 2006 and 2007 with two irrigation regimes (IW/CPE ratio of 0.6 and 0.9) and three nutrient management schedules (100% N from ramie compost, 50% N from ramie compost + 50% N from chemical fertilizer and 100% N from chemical fertilizer based) to determine the effect of irrigation and nutrient management on growth, yield and water use of ramie. Irrigation based on 0.6 IW/CPE ratio recorded higher LAI (7.4-25%), net photosynthetic rate (4.6-9.3%), dry matter (28.5 - 42.8%), fibre yield (23 – 28% ) and water use efficiency (7-19%) of ramie compared to 0.3 IW/CPE ratio irrigation treatment. In second year (2007), the LAI, net photosynthetic rate, fibre yield as well as water use efficiency of the crop receiving INM treatment (50% N from ramie compost + 50% N from inorganic source) was statistically at par to that receiving 100% N from chemical source. The results indicated that application of irrigation to ramie based on IW/CPE ratio of 0.6 and substitution of 50% of the recommended fertilizer nitrogen (15 kg/ha/cut) through integration of ramie compost in the fertilizer schedule of the crop showed better growth and fibre yield of ramie, increased the water use efficiency and economized the requirement of inorganic nitrogen by the crop and can be adopted for commercial cultivation of ramie in south Bengal condition

Search for eccentric black hole coalescences during the third observing run of LIGO and Virgo

Despite the growing number of confident binary black hole coalescences observed through gravitational waves so far, the astrophysical origin of these binaries remains uncertain. Orbital eccentricity is one of the clearest tracers of binary formation channels. Identifying binary eccentricity, however, remains challenging due to the limited availability of gravitational waveforms that include effects of eccentricity. Here, we present observational results for a waveform-independent search sensitive to eccentric black hole coalescences, covering the third observing run (O3) of the LIGO and Virgo detectors. We identified no new high-significance candidates beyond those that were already identified with searches focusing on quasi-circular binaries. We determine the sensitivity of our search to high-mass (total mass M>70 M⊙) binaries covering eccentricities up to 0.3 at 15 Hz orbital frequency, and use this to compare model predictions to search results. Assuming all detections are indeed quasi-circular, for our fiducial population model, we place an upper limit for the merger rate density of high-mass binaries with eccentricities 0<e≤0.3 at 0.33 Gpc−3 yr−1 at 90\% confidence level

Search for gravitational-lensing signatures in the full third observing run of the LIGO-Virgo network

Gravitational lensing by massive objects along the line of sight to the source causes distortions of gravitational wave-signals; such distortions may reveal information about fundamental physics, cosmology and astrophysics. In this work, we have extended the search for lensing signatures to all binary black hole events from the third observing run of the LIGO--Virgo network. We search for repeated signals from strong lensing by 1) performing targeted searches for subthreshold signals, 2) calculating the degree of overlap amongst the intrinsic parameters and sky location of pairs of signals, 3) comparing the similarities of the spectrograms amongst pairs of signals, and 4) performing dual-signal Bayesian analysis that takes into account selection effects and astrophysical knowledge. We also search for distortions to the gravitational waveform caused by 1) frequency-independent phase shifts in strongly lensed images, and 2) frequency-dependent modulation of the amplitude and phase due to point masses. None of these searches yields significant evidence for lensing. Finally, we use the non-detection of gravitational-wave lensing to constrain the lensing rate based on the latest merger-rate estimates and the fraction of dark matter composed of compact objects

Ultralight vector dark matter search using data from the KAGRA O3GK run

Among the various candidates for dark matter (DM), ultralight vector DM can be probed by laser interferometric gravitational wave detectors through the measurement of oscillating length changes in the arm cavities. In this context, KAGRA has a unique feature due to differing compositions of its mirrors, enhancing the signal of vector DM in the length change in the auxiliary channels. Here we present the result of a search for U(1)B−L gauge boson DM using the KAGRA data from auxiliary length channels during the first joint observation run together with GEO600. By applying our search pipeline, which takes into account the stochastic nature of ultralight DM, upper bounds on the coupling strength between the U(1)B−L gauge boson and ordinary matter are obtained for a range of DM masses. While our constraints are less stringent than those derived from previous experiments, this study demonstrates the applicability of our method to the lower-mass vector DM search, which is made difficult in this measurement by the short observation time compared to the auto-correlation time scale of DM
