    Air pollution is a major environmental risk to human health. Bauxite mining activity is not known to most Malaysian except recently due to environmental pollution issues in Kuantan, Pahang. These studies focus on the air pollutants from the bauxite mining activity at Bukit Goh, Pahang. Uncontrolled bauxite mining activity is a phenomenon that causes deterioration of air quality at Bukit Goh. Aluminium (Al), iron (Fe), silicon (Si), titanium (Ti), ozone (O3), nitrogen dioxide (NO2), and total suspended particulate (TSP) are the seven pollutants that were measured in this study. The concentration of air pollutants was measured at four air monitoring stations i.e. station 1, 2, 3, and 4. The air monitoring stations located based on the difference coordinates. From the study, the content of Al, Fe, Si, Ti, and TSP were determined by using the MiniVol Portable Air Sampler. Al, Fe, Si, and Ti were determined by the analysis of the TSP trapped on the filter paper. The readings were recorded for 24 hours. O3and NO2 were measured using Toxic Gas TG-501. The readings were recorded for 1 hour. The samples collected were analysed using the Gaussian Plume Dispersion Model (GPDM) to estimate the concentration of a pollutant. While Surfer 8 Software was used to determine the air pollution distribution. The data of wind speeds were obtained from the Jabatan Meteorologi Pahang. The result of air pollutants was compared using the mean speed of 1.8 m/s and maximum speed of 2.7 m/s. It was found that the maximum concentrations of air pollutants exist at the mean speed of 1.8 m/s. From the results analysis, the concentrations of O3, NO2, TSP, Al, Si, and Ti are 82.250µg/m³, 263.784µg/m³, 306.330µg/m³, 27.496µg/m³, 110.449µg/m³, and 0.5080µg/m³ respectively. But Fe is not found in this study. TSP shows a high value of concentration because it is higher than the value in the Recommended Malaysian Air Quality Guidelines. According to the Recommended Malaysian Air Quality Guidelines, the maximum concentration of TSP is 260µg/m³. This shows that the environment in Bukit Goh is polluted. In this study, the concentrations and distributions of air pollutants are influenced by meteorological factors

    في الوقت الحاضر، لم يعد تعبير الأشخاص على الإنترنت يقتصر على النصوص، خاصة مع ظهور طفرة الفيديو القصير، مما أدى إلى ظهور عدد كبير من البيانات النموذجية مثل النصوص والصور والصوت والفيديو. بالمقارنة مع بيانات الوضع الفردي، تحتوي البيانات متعددة الوسائط دائمًا على معلومات ضخمة. يمكن أن تساعد عملية التنقيب في المعلومات متعددة الوسائط أجهزة الكمبيوتر على فهم الخصائص العاطفية البشرية بشكل أفضل. ومع ذلك، نظرًا لأن البيانات متعددة الوسائط تُظهر ميزات سلسلة زمنية ديناميكية واضحة، فمن الضروري حل مشكلة الارتباط الديناميكي داخل وضع واحد وبين أوضاع مختلفة في نفس مشهد التطبيق أثناء عملية الدمج. لحل هذه المشكلة، في هذا البحث، تم إنشاء إطار استخراج ميزة للتوسع الديناميكي ثلاثي الأبعاد بناءً على البيانات المشتركة متعددة الوسائط، على سبيل المثال الفيديو والصوت والنص. إطار عمل مطابق يعتمد على تحسين الميزات المكانية والزمانية، على التوالي لحل الارتباط الديناميكي داخل الأوضاع وفيما بينها، ومن ثم نمذجة معلومات الارتباط الديناميكي قصيرة وطويلة المدى بين الأوضاع المختلفة بناءً على الإطار المقترح. تُظهر التجارب الجماعية المتعددة التي تم إجراؤها على مجموعات بيانات MOSI  أن نموذج التعرف على المشاعر الذي تم إنشاؤه بناءً على الإطار المقترح هنا في هذه الدراسة يمكنه الاستفادة بشكل أفضل من المعلومات التكميلية الأكثر تعقيدًا بين البيانات المشروطة المختلفة. بالمقارنة مع نماذج دمج البيانات متعددة الوسائط الأخرى، فإن إطار دمج البيانات متعدد الوسائط القائم على الاهتمام المكاني والزماني المقترح في هذه الورقة يحسن بشكل كبير معدل التعرف على المشاعر ودقتها عند تطبيقها على تحليل المشاعر متعدد الوسائط، لذلك فهو أكثر جدوى وفعالية.Nowadays, people's expression on the Internet is no longer limited to text, especially with the rise of the short video boom, leading to the emergence of a large number of modal data such as text, pictures, audio, and video. Compared to single mode data ,the multi-modal data always contains massive information. The mining process of multi-modal information can help computers to better understand human emotional characteristics. However, because the multi-modal data show obvious dynamic time series features, it is necessary to solve the dynamic correlation problem within a single mode and between different modes in the same application scene during the fusion process. To solve this problem, in this paper, a feature extraction framework of the three-dimensional dynamic expansion is established based on the common multi-modal data, for example video , sound ,text.Based on the framework, a multi-modal fusion-matched framework based on spatial and temporal feature enhancement, respectively to solve the dynamic correlation within and between modes, and then model the short and long term dynamic correlation information between different modes based on the proposed framework. Multiple group experiments performed on MOSI datasets show that the emotion recognition model constructed based on the framework proposed here in this paper can better utilize the more complex complementary information between different modal data. Compared with other multi-modal data fusion models, the spatial-temporal attention-based multimodal data fusion framework proposed in this paper significantly improves the emotion recognition rate and accuracy when applied to multi-modal emotion analysis, so it is more feasible and effective

    Get PDF
    Black soldier fly larvae (BSFL) are a good source of protein for aquaculture, animal feed, pet and human nutrition. Larvae have a healthy appetite and can be used to make household waste compost and residual agricultural. For previous study [1], observed that the BSFL can be grown in a variety of organic waste stream including pig manure, kitchen waste, fruits and vegetables, and given to the fish. In addition, the larvae benefit from the use of natural resources to overcome the problem of life cycle of widespread flies in the poultry farm openly. Therefore, it is important to note that the poultry farms release many particles into the air that endanger human health and the environment

    Willingness to whistle blow among Muslim consumers

    Get PDF
    The paper reports on a qualitative study using three focus groups drawn from Muslim consumers both local and foreign. Respondents were given vignettes depicting unethical halal claims scenarios to which respondents were required to respond. Two Malaysian consumer groups responded by declaring that they will whistle blow by reporting the matter to a religious authority, the Islamic Development Department (JAKIM), while another group that consists of six Muslim foreign students will just leave the business premise without making any complaints to any authority. The different course of actions taken could be explained by the diverse background of the Malaysian population and their level of awareness in selecting their halal food and their high degree of intolerance to such practice whilst the level of tolerance among foreign Muslim respondents might be different from their Malaysian counterparts or that they have never encountered such a problem before they came to Malaysia. The study also reports the response from JAKIM in relation to the relevant channels for whistle blowing regarding misleading halal labels

    Recently wireless mesh networks (WMNs) gained significant roles in the current communication technologies and have been used in numerous applications such as transportation systems, rescue systems, Surveillance systems, community and neighborhood networking and etc. Therefore, many researchers pay their attention to the wireless mesh network issues especially the gateway placement optimization problems. In this paper, we study and investigate the efforts of many researchers that dealt with the gateway placement optimization problem based on combinatorial optimization concepts in comparison with other conventional algorithms as well as comparing the combinatorial based algorithms with each other. The investigation result shows that the genetic algorithms based approaches on solving gateway optimization problem relatively outperform many other approaches in addition to that the strength of the genetic algorithm depends on the fitness function which is used in measuring the quality of the individuals (fitness value)

    Suitability study on chicken dung and fruit waste as Black Soldier Fly Larvae (BSFL) diet

    Get PDF
    Production of chicken increases due to the demand of their eggs and meats [1]. As a result, a massive amount of chicken dung has been generated. Raw chicken dung has adverse effect on plants. Therefore, it should be composted or aged prior to use as raw chicken dung as it contains pathogens as well as urine, feathers, undigested food and coop bedding material that can harm people and animals [2]. If composting is properly done, the process destroys disease-causing organisms, making chicken dung safe to be used around plants, people and pets [2]. Chicken dung is rich in nitrogen, potassium, phosphorus and calcium, and also rich in organic matter compared to other manures. The addition of organic matter to soils increases water-holding capacity of soil, improves aeration and drainage, reduces erosion, reduces fertilizer leaching and improves soil structure for plants [2]. Furthermore, organic matter provides food source for soil microbes, which increases soil biological diversity, accelerates the breakdown of organic nutrients for plants to improve plant health.

    Food waste is the largest component in municipal solid waste (MSW). About 1.3 billion tons of food, which is equivalent to one third of global food production is lost or wasted every year along the food supply chain [1]. In Malaysia, total generation of MSW is 15,000 tons. This MSW consists of 50% food waste, of which 70% is disposed at the landfill sites [2]. It was reported that in average a household in Malaysia throw away around 0.5-0.8 kg uneaten food per day [3]. This food waste is recognized as huge problem worldwide and it becomes particularly severe to developing country. There are many methods that can be carried out to reduce the food waste generation. Composting method is one of the methods to convert food waste into valuable product with minimum cost

    Improvised design of grease trap for the usage at the food premises

    In Malaysia, there are many pollutions that emitted from the industry. Water pollution can be caused by various sectors, one of it is the industrial sector of the food service. The food service industry in Malaysia is growing up every day and they are the major contributor to pollution that was caused by fats, oils, and grease that are highly discharged from food premises. Grease traps are widely used by most restaurants and food processing industries to reduce oil and grease to an acceptable level before it can be discharged to public sewers [1]. Grease traps are a pipeline that traps the food waste before they enter the sanitary sewer system. The food waste is from the fats, oils, and greases and is usually found in kitchen waste water. Normally, the grease traps are located under the sink because the place is usually contributed to fat, oil and grease. Among the alternatives to reduce the emission levels of fats, oil, and grease, the uses of the grease trap is required to filter the wastewater released from the premises [2]
