Replacement of fish meal by plant protein sources in Nile tilapia (Oreochromis niloticus) diet: growth performance and utilization

The nutritional suitability and cost effectiveness of rice polish and mustard oil cake as protein sources in the diet of Nile tilapia (Oreochromis niloticus) were studied. This study introduced rice polish as a plant protein source for Nile tilapia and three diets were formulated using rice polish (0, 10 and 20%) and mustard oil cake (10.0, 17.6 and 22.0%) for a feeding trial of eight weeks to observe the growth performance and feed utilization. The result was indicated that growth performance tended to decrease with increase in inclusion level of rice polish and mustard oil cake. The control diet (FM35) recorded the highest body weight gain (BWG) (363.79±59.32%) and the least (330.24±32.32%) was in diet FM25. Specific growth rate (SGR) was followed the same trend and no significant differences of SGR was observed among the diets (P>0.05). Feed intake (FI) of different diets was ranged between 30.33 g and 35.08 g per fish at the end of this experiment. Feed intake was also declined with the increase in inclusion level of rice polish, though the feed conversion ratio (FCR) and protein efficiency ratio (PER) were not significantly different (P>0.05) among the diets. The results of this study revealed that partial replacement of fish meal by rice polish and mustard oil cake would be cost effective without any significant change in growth performance

Internet-based Framework to Support Integration of Customer in the Design of Customizable Products

A necessary element to design and produce customer-centric products is the integration of customers in the design process. Challenges faced during customer integration into the design process include generating models of the customized product, performing analysis of these to determine feasibility, and optimizing to increase the performance. These tasks have to be performed relatively quickly, if not in real time, to provide feedback to the customer. The focus of this article is to present a framework that utilizes CAD, finite element analysis (FEA), and optimization to integrate the customer into the design process via the Internet for delivering user customized products. The design analysis, evaluation, and optimization need to be automated and enhanced to enable operation over the Internet. A product family CAD/FEA template has been developed to perform analysis, along with a general formulation to optimize the customized product. The CAD/FEA template generalizes the geometry building and analysis of each configuration developed using a product platform approach. The proposed setup is demonstrated through the use of a bicycle frame family. In this study, the focus is on the application of optimization and FEA to facilitate the design of customer-centric products.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline

Zero-Shot Generalizable End-to-End Task-Oriented Dialog System using Context Summarization and Domain Schema

Task-oriented dialog systems empower users to accomplish their goals by facilitating intuitive and expressive natural language interactions. State-of-the-art approaches in task-oriented dialog systems formulate the problem as a conditional sequence generation task and fine-tune pre-trained causal language models in the supervised setting. This requires labeled training data for each new domain or task, and acquiring such data is prohibitively laborious and expensive, thus making it a bottleneck for scaling systems to a wide range of domains. To overcome this challenge, we introduce a novel Zero-Shot generalizable end-to-end Task-oriented Dialog system, ZS-ToD, that leverages domain schemas to allow for robust generalization to unseen domains and exploits effective summarization of the dialog history. We employ GPT-2 as a backbone model and introduce a two-step training process where the goal of the first step is to learn the general structure of the dialog data and the second step optimizes the response generation as well as intermediate outputs, such as dialog state and system actions. As opposed to state-of-the-art systems that are trained to fulfill certain intents in the given domains and memorize task-specific conversational patterns, ZS-ToD learns generic task-completion skills by comprehending domain semantics via domain schemas and generalizing to unseen domains seamlessly. We conduct an extensive experimental evaluation on SGD and SGD-X datasets that span up to 20 unique domains and ZS-ToD outperforms state-of-the-art systems on key metrics, with an improvement of +17% on joint goal accuracy and +5 on inform. Additionally, we present a detailed ablation study to demonstrate the effectiveness of the proposed components and training mechanis

Heterogeneous reactor systems for 4-chlorophenol removal from aqueous streams using horseradish peroxidase enzyme.

Horseradish peroxidase (HRP) is a robust enzyme that catalyzes a wide variety of reactions involving aromatic compounds. The enzyme once activated by hydrogen peroxide initializes polymerization reactions of different aromatic compounds. The products of reaction are water insoluble and can be separated easily. Since HRP is relatively inexpensive and readily available, the process has great promise for removing aromatic compounds from industrial wastewaters which are not effectively removed by conventional biological or physico-chemical wastewater treatment methods. Removal of 4-chlorophenol with HRP was investigated in three immobilized enzyme reactor systems using HRP: cellulose filter, nylon balls and nylon tubing. The enzyme catalyzed a different number of reactions in each case. Nylon balls provided turnover numbers up to 52 000 in batch reactor operation. For cellulose disks it varied from 6 000 to 13 000 and was proportional to substrate concentration. For nylon tubing the maximum turnover number was 12 400. The chemical reaction in all cases was extremely fast and achieved more than 95% removal efficiency when enzyme activity was not limiting. Initial reaction rates exhibited hyperbolic kinetics. The reaction was mainly mass transfer controlled at contaminant concentrations less than 1 mM. Two mathematical models, based on bulk phase concentration, were developed to simulate the batch reactor systems. The single parameter model was extended to predict continuous flow reactor system behaviour. All the models were tested using the data collected in this study.Dept. of Civil and Environmental Engineering.
