ENHANCING GERMINATION AND SEEDLING VIGOR IN NIGELLA SATIVA: THE IMPACT OF NANO IRON OXIDE AND PHOSPHORUS PRIMING

Hatice Kübra Gören — 2024-09-23

Nigella sativa, commonly known as black cumin, is known for its health benefits due to its rich content of compounds like thymoquinone. This study explored the effects of various seed priming methods on Nigella sativa seeds, including control (unprimed), distilled water, nano iron oxide (Fe₂O₃), phosphorus (P), and a combination of Fe₂O₃ and P. We assessed how these treatments influenced several key aspects of seed germination: germination rate (GR), mean germination time (MGT), germination index (GI), coefficient of velocity of germination (CVG), and vigor index (VI).
Our results showed that seeds treated with Fe₂O₃ nanoparticles had the highest germination rate at 93.5% and germinated faster than seeds from other treatments. This suggests that Fe₂O₃ nanoparticles effectively speed up the germination process. However, despite the improved germination rate, the seeds treated with Fe₂O₃ did not exhibit the highest seedling vigor; the control seeds had the highest vigor index, indicating that while Fe₂O₃ accelerates germination, it does not enhance seedling health as much as the untreated seeds. Additionally, there were no significant differences in the germination index and coefficient of velocity of germination between the treatments, suggesting these parameters were less influenced by the priming methods.
In summary, nano-priming with Fe₂O₃ is effective for speeding up seed germination but does not necessarily improve seedling vigor. These findings provide valuable insights into how different priming techniques can be optimized to enhance seed performance and plant growth under various conditions.

NAVIGATING ORGANIZATIONAL TRANSITIONS SMOOTHLY: A COO’S GUIDE TO EFFECTIVE CHANGE MANAGEMENT

Anitha G. — 2024-09-26

In today's dynamic business environment, organizational transitions are not just occasional occurrences but rather constant features of the landscape. Emphasize the pivotal role of COOs in orchestrating smooth transitions. Chief Operating Officers (COOs) serve as linchpins in facilitating these transitions, ensuring they unfold seamlessly. Effective change management becomes imperative for minimizing disruptions and sustaining operational excellence. Establish open channels of communication to keep employees informed throughout the transition process. Clearly articulate the reasons behind the transition and the anticipated outcomes. Encourage feedback and address concerns promptly to mitigate resistance. Collaborate with department heads, team leaders, and employees to solicit valuable insights and perspectives. Anticipate potential challenges and develop contingency plans to mitigate risks and minimize disruptions. The strategies COOs can employ to navigate organizational transitions adeptly, fostering a culture of adaptability and resilience within their organizations.

ASSESSMENT OF WATER QUALITY PARAMETERS AND ITS EFFECTS ON THE HEALTH OF RESIDENTS OF ANTA DIVISION OF BARAN DISTRICT, RAJASTHAN

Ramet Meena — 2024-09-26

Water is the basic resource necessary for sustaining all human activities, so its provision in desired quantity and quality is of utmost importance. The present study is focused on measuring the quality drinking water in rural and urban areas of Anta division of Baran district, Rajasthan, India and its effects on human health as told by the people living in these areas. Water pollution affects drinking water, rivers, lakes and oceans all over the world, which consequently harms human health and the natural environment. Various analyses including physical, chemical and biological assessment were carried out on the drinking water samples collected from the selected villages in Anta division. The drinking water samples were found to have high pH, Total dissolved solid (TDS), Calcium hardness (CaH), Magnesium hardness (MgH) etc in the water samples. On the contrary to these findings, majority of people living in these areas were not suffering from various water borne diseases. So the study argues about the need and importance of water purification and water management systems in current times.

DISCLOSING MONETARY TERMS OF R&D ALLIANCES

Edward Levitas — 2024-09-27

We investigate how biotechnology and pharmaceutical R&D alliances operating in an emerging and uncertain environment affects the partner’s decisions to provide unmandated alliance monetary terms. We identify factors promoting R&D alliance partners' desire to disclose monetary arrangements, and factors compelling firms to conceal these arrangements. Voluntarily disclosed monetary arrangements of R&D alliances may impact the overall success of the alliance, partners' performance independent of the alliance, and future R&D costs. Disclosure likely lowers the future cost of capital for certain partners, reducing future R&D costs; yet, disclosure may inadvertently provide proprietary information to competitors. Biotechs seek partnership with pharmaceuticals with established track records in getting drugs to market. Pharmaceuticals seek partnerships with biotechs possessing skills, (i.e. R&D research). We contend the biotech partner's stock price uncertainty and near-term financial capital needs and the larger pharmaceutical firm's market experience will impact the decision to disclose alliance monetary arrangements. We find support for our hypotheses using Probit regressions.
