Monoclonal antibodies in fish and shellfish health management in India
The paper describes the superiority of monoclonal antibodies (MAb) over conventional polyclonal antisera. Studies undertaken indicate that Aeromonas hydrophila isolates are highly heterogenous and variation exists even between isolates from a farm, requiring a large number of MAbs for classification and use of information in vaccine development. However, some of the MAbs could be used for detection of homologous isolates in fish kidney by immunodot assay and evaluation and standardization of biofilm of A. hydrophila for oral vaccination in carps
Opinion Poll: Big Data Implementation of Unstructured Data Analytics of Social Network Reviews Using Sentiment Analysis SVM
Recent systems developed are dependent on user feedbacks or opinions. These feedbacks or opinions are generated in volumes everyday which are difficult to filter and analyse. We propose Sentiment based analysis is the major key in categorizing the user\u27s Feedback. In thispaper, we study the processing of all the reviews posted in an online shopping application and classify them using SVM. We use big data to analyze the vast amounts of data generated. User reviews are the input to the Big Data HDFS System. Data are stored in the Data Nodes. Index is maintained in the Name Node. Reviews are analyzed using Sentiment Analysis and Positive Negative Tweets are classified. Also products are recommended based on the previous purchases and group notification is sent to all the customers in a group

Evaluation of Role of Ct Enterography in the Diagnosis of Small Bowel Pathology
Background: Aim: This study prospectively evaluates the role of CT Enterography(CTE) in diagnosis of small bowel pathology.
Materials and Methods: This prospective observational study was conducted on 42 consecutive patients with suspected small bowel pathology. CTE was performed using polyethylene glycol(PEG) as oral neutral contrast agent. After ingestion of 2 L of PEG solution, plain and dual phase contrast CT scan was performed on all patients. Raw data and reconstructed images were studied on PACS workstation and degree of small bowel distension was assessed, abnormal small bowel was identified and studied in detail to arrive at a diagnosis. Statistical analysis was performed and sensitivity, specificity, PPV, NPV and accuracy were calculated by comparison of CTE with surgery and histopathology as Gold Standard.
Results: In our study,age of the patient ranged from 18 to 75 years,maximum number of subjects were between 21 and 40 years of age. Abnormal small bowel was diagnosed in 15/42 (35.7%) patients. CTE correctly diagnosed Crohn’s disease in 5/6 cases (83%), small bowel adhesions in 4/4 cases (100%) and TB in 1/1 case (100%). We found that the overall accuracy of CTE in diagnosis of small bowel pathology was good. Sensitivity of CTE was found to be 100% for Crohn’s, bowel adhesions and abnormal small bowel in general and specificity to be 97.06%, 100% and 96.30 % respectively.However, the sensitivity for tuberculosis was found to be low, only 50% while specificity was 100.0%. This was in comparison with reference standard of surgery and/ or histopathology.
Conclusion: CTE with large volume of PEG electrolyte solution as neutral oral contrast agent provides optimal luminal distension and adequate small bowel separation, thus enabling identification of mural changes, mucosal hyperenhancement, luminal as well as extraluminal abnormalities and active site of bleeding in cases of Gastro-intestinal bleed. In our study, we found CTE to be a highly sensitive and specific method for diagnosing small bowel pathology in accordance with other studies in the literature
ACTIVE-HASH-TABLE BASED PUBLIC AUDITING FOR SECURE CLOUD STORAGE
Public auditing scheme for secure cloud storage based on dynamic hash table, which is a new two-dimensional data structure located at a third-party auditor (TPA) to record the data property information for dynamic auditing. Differing form the existing works, the proposed scheme migrates the authorized information from the cloud services provider to the TPA and thereby significantly reduces the computational cost and communication overhead. Our scheme can also achieve higher updating efficiency than the state of the art schemes. In addition, we extend our scheme to support privacy preservation by combining the homomorphic authenticator based on the public key with the random masking generated by the TPA and achieve batch auditing by employing the aggregate BLS signature technique. We formally prove the security of the proposed scheme and evaluate the auditing performance by detailed experiments and comparisons with the existing ones. The results demonstrate that the proposed scheme can effectively achieve secure auditing for cloud storage and outperform the previous schemes’ in computation complexity, storage costs, and communication overhead

The Effect of Crop Growth Stage on the Formation And Ability of Carbon Occlusion within Phytoliths in Rice Varieties
Carbon occlusion refers to the process by which carbon dioxide is incorporated into the silica structure of phytoliths during their formation. Microscopic silica formations called phytoliths develop inside plant cells. Phytoliths are microscopic, silica-based structures that develop inside plant cells. These silica bodies are deposited in various parts of the plant, such as leaves, stems, and reproductive organs. Carbon occlusion within phytoliths can potentially act as a long-term carbon sink, aiding in the mitigation of greenhouse gas emissions and climate change. They are commonly found in various plant species, including rice. This study focuses on investigating how the growth stage of rice crops affects the process of carbon occlusion within phytoliths. Phytoliths play important roles in plant structure, defense mechanisms, and carbon storage. The research study aims to examine how different growth stages of rice crops influence the formation of phytoliths and the extent to which carbon is occluded within them. It may involve conducting experiments or observations at different growth stages of rice plants, such as the seedling stage, vegetative stage, flowering stage, or maturity stage. The findings of this research could contribute to our understanding of the carbon sequestration potential of rice crops and how it varies throughout their growth cycle
