Demand of bricks is increasing day by day by the requirement of new structures. Due to manufacturing of bricks, over-burnt bricks are also made. Generally over-burnt bricks are the waste materials which is generally used for dumping purpose and sometime it is thrown in useful land that create social and environmental problems. Therefore, this material should be properly treated, recycled and used in concrete as coarse aggregate. In this research work, six (06) batches were made with 1:2:4 mix and 0.5 water cement ratio. Each batch consists of five (05) samples. Six (06) batches were made with 0%, 20%, 40%, 60%, 80% and 100% replacement of natural coarse aggregates with over-burnt bricks aggregates. The outcome of study reveals that the gradation of both the aggregates shows same pattern and the trend of curve was almost similar, with minor difference in range values over a sieve. The water absorption of over-burnt bricks aggregates was more than the water absorption of natural coarse aggregates and the specific gravity of over-burnt bricks aggregates was less than the specific gravity of natural coarse aggregates. The result of slump test shows that there was continuous decrease in workability of concrete mix, as replacement of over-burnt bricks aggregates increased. 30 concrete cubes of (6” x 6” x 6”) size were prepared and cured for 28 days followed by compressive strength. The result shows that the concrete derived from over-burnt bricks aggregates attained lower compressive strength than the regular concrete. However, the values obtained from over-burnt bricks aggregates are still acceptable, especially for reasonable levels of the replacement ratio up-to 60%. This concrete can be used in new constructions, but it is proposed to be initially utilized in low load areas.
由于新建筑的需求,对砖块的需求与日俱增。在生产砖块的过程中,也会产生过烧砖。一般来说,过烧砖是一种废料,通常用于倾倒,有时也会被扔到有用的土地上,造成社会和环境问题。因此,应妥善处理和回收这些材料,并将其用作混凝土的粗骨料。在这项研究工作中,采用 1:2:4 的混合比例和 0.5 的水灰比制作了六(06)批混凝土。每批包括五(05)个样品。六(06)批次样品分别用 0%、20%、40%、60%、80% 和 100% 的过烧砖骨料替代天然粗骨料。研究结果表明,两种骨料的级配显示出相同的模式,曲线趋势也几乎相似,只是筛上的范围值略有不同。过烧砖集料的吸水率高于天然粗集料的吸水率,过烧砖集料的比重小于天然粗集料的比重。坍落度试验结果表明,随着过烧砖骨料替代量的增加,混凝土拌合物的工作性持续下降。制备了 30 个尺寸为(6 英寸 x 6 英寸 x 6 英寸)的混凝土立方体,养护 28 天后进行抗压强度测试。结果表明,使用过烧砖骨料制成的混凝土抗压强度低于普通混凝土。不过,过烧砖骨料的抗压强度值仍然可以接受,尤其是在合理的替代率水平(最高达 60%)下。这种混凝土可用于新建筑,但建议首先用于低荷载地区。

The growing interest in the fish farming industry is driven by the depletion of natural fish stocks in the market. However, intensive aquaculture systems, which involve raising fish in artificial tanks and cages, can lead to challenges such as low-quality fish and increased mortality rates, depending on the species being cultivated. To address these issues and maximize yield, this paper proposes a fish quality monitoring system with automatic correction. The system focuses on monitoring and maintaining critical water quality parameters essential for fish growth, including temperature, water level, and pH level. The system comprises an Arduino connected to sensors and a web-based application for data collection and monitoring. Correction devices such as an aquarium heater, a valve, and a water pump are integrated into the system to maintain these parameters at optimal levels for fish development. To assess the system's efficiency and reliability, two fish monitoring setups were compared: one using the proposed controlled system and the other using a traditional setup. Results indicate that the controlled system increased efficiency, reduced stress on fish farmers, decreased fish mortality rates, and improved product quality compared to the traditional setup.
由于市场上的天然鱼类资源枯竭,人们对养鱼业的兴趣与日俱增。然而,集约化水产养殖系统涉及在人工水箱和网箱中养鱼,可能会导致鱼类质量低下和死亡率上升等挑战,具体取决于养殖的鱼种。为了解决这些问题并最大限度地提高产量,本文提出了一种可自动校正的鱼类质量监测系统。该系统侧重于监测和维护鱼类生长所必需的关键水质参数,包括温度、水位和 pH 值。该系统由一个与传感器相连的 Arduino 和一个用于数据收集和监控的网络应用程序组成。系统中还集成了水族箱加热器、阀门和水泵等校正装置,以将这些参数维持在鱼类生长所需的最佳水平。为了评估该系统的效率和可靠性,对两种鱼类监测装置进行了比较:一种是使用建议的受控系统,另一种是使用传统装置。结果表明,与传统设置相比,受控系统提高了效率,减轻了养鱼户的压力,降低了鱼类死亡率,并提高了产品质量。

Water irrigation remain as a challenge to supply adequate amount of water to sustain the growth of plant and crops yield along the year in certain part of the world which are heavily affected by climate change. This scenario creates a huge risk toward the world food supply chain. Hence, the application of smart farming system is crucially important now to pave the way for a better the agriculture monitoring system to replace traditional manual monitoring labour by farmers. The smart farming system are usually equipped with environmental stimuli sensing system such as temperature, humidity, soil moisture, light intensity sensing sensors coupled with automation actuators to control the water irrigation rate for the crops in order to save water and at the same time provide adequate water supply for plant growth. The aim of using such smart farming system is to enable higher crops production and less human labour at the same time optimising resources available to minimize cost of farming. Hence, this paper aims to introduce a novel approach of a Raspberry Pi powered IoT smart farming system (ISFS) which can incorporate autonomous monitoring of plant irrigation, temperature, humidity, soil moisture and light intensity, to design a smartphone app that allows users to monitor plantation-related conditions in a user-friendly manner, and to enable automatic control of a drip irrigation system for plants based on data obtained on soil moisture, temperature and sunlight intensity. The proposed prototype with the functionality mentioned is aim to resolve the existing problem and to meet the demand of smart farming application in current era.

This Various text summarization methods, such as extractive, abstractive, and human abstraction concepts have been compared in terms of performance, each with its specialties and limitations. This research analyses comparisons among the methods and some of their techniques used in text summarization. Our initial contribution is to suggest a thorough overview of the methods. The research methodology aims to compare text summarization methods through a systematic literature review to understand the topic and select appropriate methods. The search method involves keyword-based and citation-based techniques using academic search engines. The comparison of methods will consider various evaluation criteria such as document structure, content importance, quantitative approach, qualitative approach, dependency on machine learning, sentence generation, central concept identification, human involvement, representation in mathematics, and historical approaches. The methods would be evaluated based on these criteria to provide an objective and comprehensive comparison. No method consistently produces accurate text summaries. The best course of action will depend on the particulars and constraints of the current work because each method has both positive and negative aspects. The two primary methods for text summarization were discovered to be extractive and abstractive. This comparison study analysed various text summary and revealing each method's positive attributes and drawbacks. By giving a comprehensive overview of the main two methods, this comparative analysis advances the subject of text summarizing.

Oil authentication has been widely discussed in recent years. One of the issues is the usage of gutter oil. This happened in China where many of the street foods were prepared using oils from sewage, gutters, and restaurant fryers. Other concerning issues including the adulteration of high-quality edible oils with cheaper oils and fresh palm oil with recycled cooking oil are common problems related to oil fraud. This may provoke the safety and the rights of public consumers. Hence, advanced, efficient, and rapid technology such as Fourier Transform Infrared Spectroscopy (FTIR) is needed to overcome the limitations of other technologies such as differential scanning calorimetry (DSC), gas chromatography-mass spectrometry (GC-MS) and high-performance liquid chromatography (HPLC) in analysing edible oils’ quality parameters, authentication, safety, stability and in foods related to oils. This review discusses the uses of FTIR in the analysis of edible oils and their authentication.
近年来,油品认证问题一直被广泛讨论。其中一个问题就是地沟油的使用。在中国,许多街头小吃都是用污水、地沟油和餐馆油炸锅里的油烹制的。其他令人担忧的问题包括用廉价油掺杂优质食用油和用回收食用油掺杂新鲜棕榈油,这些都是与油品欺诈有关的常见问题。这可能会危及公众消费者的安全和权益。因此,在分析食用油的质量参数、鉴定、安全性、稳定性以及与油有关的食品时,需要傅立叶变换红外光谱法(FTIR)等先进、高效、快速的技术来克服差示扫描量热法(DSC)、气相色谱-质谱法(GC-MS)和高效液相色谱法(HPLC)等其他技术的局限性。本综述讨论了傅立叶变换红外光谱在食用油分析和鉴定中的应用。

Breast cancer is a highly common and life-threatening disease that affects people worldwide. Early and accurate diagnosis of breast cancer can enhance patients' prognosis and survival rate. This paper conducts a comparative examination of the Wisconsin Breast Cancer Diagnostic (WBCD) dataset by employing four distinct deep learning models: Feedforward Neural Network (FNN), Convolutional Neural Network (CNN), Long Short-Term Memory (LSTM), and Gated Recurrent Unit (GRU). The collection consists of 569 examples of Fine Needle Aspirate (FNA) photographs of breast cancers, with each case containing thirty parameters that define the features of the cell nuclei. By doing a comparative analysis of the advantages and disadvantages of the models, we will evaluate them based on their accuracy, precision, recall, and F1-score. Based on our research, CNN achieves the best level of accuracy at 98.25%, which is followed by GRU at 97.37%, FNN at 96.49%, and LSTM at 95.61%. It is determined that CNN is the most suitable model for this task and that deep learning models are valuable and encouraging tools for diagnosing breast cancer.
