Evaluation of Various Cotton Cultivars for Seed Cotton Yield and Related Attributes at Different Nitrogen Levels

Response of four cotton cultivars viz., CIM-598, CIM-599, CIM-602 and Ali akbar 703 to different nitrogen levels (0, 50, 100, 150 and 200 kg ha-1) was investigated during the cropping season 2014 at Cotton Research Station, Dera Ismail Khan, Pakistan. Results revealed that application of N dominantly increased plant height, boll weight, number of bolls per plant and seed cotton yield but different cultivars responded differently in increase over control. The maximum seed cotton yield observed was 2579.65 kg ha-1 and 200 kg ha-1 was proved to be the best level for maximum seed cotton yield. Non-significant interaction was observed for all the studied parameters whereas cotton cultivars varied significantly (P≤0.05) for seed cotton yield on account of boll weight and number of bolls per plant. Overall maximum Seed cotton yield was observed in Ali akbar 703 (3093.26 kg ha-1) at all N levels suggesting that it could be the promising cotton cultivar under the agro climatic conditions of Dera Ismail Khan and could be grown by supplying 200 kg N ha-1. As steeply linear increase in all the studied attributes was recorded up to 200 kg N ha-1, studies with further higher levels (beyond 200 kg N ha-1) are suggested for confirmation of the present findings.

A manufacturing core concepts ontology to support knowledge sharing

Knowledge sharing across domains is key to bringing down the cost of production and the time to market of products. This thesis is directed to improve the knowledge sharing capability of the present systems that use information and communication technologies. Systems for different domains have structures that are made up of concepts and relations with different semantic interpretations. Therefore, knowledge sharing across such domains becomes an issue. Knowledge sharing across multiple domains can be facilitated through a system that can provide a shared understanding across multiple domains. This requires a rigorous common semantic base underlying the domains across which to share knowledge. [Continues.

Sustainability in the Norwegian aquaculture industry: The green financing, accreditation and certification conundrum

This thesis explores the conundrum of green financing, accreditation, and certification in the context of sustainability in the Norwegian aquaculture industry. As the demand for sustainable practices in aquaculture continues to grow, the industry faces the challenge of reconciling financial considerations with environmental objectives. The study highlights sustainability and how it encompasses various dimensions, including environmental, financial and productive considerations, as it has become a key focus in the global discourse on responsible resource management. It then examines the role of green financing instruments, such as green bonds, in promoting sustainable initiatives and attracting capital for environmentally friendly projects. It also delves into the complexities arising from the presence of multiple accreditation and certification schemes, which create ambiguity and hinder comparability of environmental performance. To give this scenario an on-going context, this paper compares leading Norwegian aquacultural companies; SalMar, Mowi & Grieg Seafood, in terms of their role and involvement in achieving sustainable practices as well as securing capital from green-financing. The research highlights the need for harmonization and standardization efforts to ensure transparency, credibility, and accountability. Moreover, the thesis underscores the importance of collaboration between industry stakeholders, regulators, and NGOs to address the challenges and advance sustainable practices. Through a comprehensive analysis of the green financing, accreditation, and certification landscape, this study provides valuable insights and recommendations for achieving sustainability in the Norwegian aquaculture industry. By considering the complexities and embracing a multi-faceted approach, the industry can navigate the conundrum and make significant progress towards a more sustainable future

Toward high-quality gradient estimation on regular lattices

Abstract—In this paper, we present two methods for accurate gradient estimation from scalar field data sampled on regular lattices. The first method is based on the multidimensional Taylor series expansion of the convolution sum and allows us to specify design criteria such as compactness and approximation power. The second method is based on a Hilbert space framework and provides a minimum error solution in the form of an orthogonal projection operating between two approximation spaces. Both methods lead to discrete filters, which can be combined with continuous reconstruction kernels to yield highly accurate estimators as compared to the current state of the art. We demonstrate the advantages of our methods in the context of volume rendering of data sampled on Cartesian and Body-Centered Cubic lattices. Our results show significant qualitative and quantitative improvements for both synthetic and real data, while incurring a moderate preprocessing and storage overhead. Index Terms—Approximation theory, Taylor series expansion, normal reconstruction, orthogonal projection, body-centered cubic lattice, box splines. Ç

Posterior Fossa Dermoid Cyst in a Child with Recurrent Meningitis

Intra cranial dermoid cysts are rare brain tumors. Cutaneous punctum extending in cranial cavity as dermal tract or intermittent seepage from the cyst in subarachnoid space can be a source of recurrent meningitis. We report a 5 years child with posterior fossa dermoid cyst presented to pediatrician with recurrent episode of meningitis. Diagnosis was made on CT / MRI images. Safe total excision was performed and patient was sent home safely on 4th postoperative days without any complication

Dynamics of political usage of smart phones: Examining relationship of exposure patterns and polarization among young voters

Mobile phones are credited to be the fastest penetrating technology among Pakistani youth. The study examines the role of selective exposure in polarization among young voters during General Elections of Pakistan, 2013. It highlights the relationship between usage of mobile phones for political messages and tendency of users to attend and share selective as well as diverse views and alternative perspectives. Findings from 200 respondents through survey method reveal that selective exposure of young voters is on decline and they engage themselves to diverse contents as well. Thus, polarization patterns of Pakistani youth are changing in relation to mobile usage
