It establishes the type of business the company is operating and how it is important in the context of Bangladesh. Being the initiator of AceQuad Startup Services I first thought of solving such problems and meeting such needs of the customers. In the context of Bangladesh, as the average income is not much high people are always searching for a reasonable price. And in terms of offering a reasonable price it is much helpful if the services can be offered in bulk. In this way the prices can be reduced to a minimum as well as profits can also be maximized. For this reason, AceQuad Startup Network set up a strategy that we are going to offer all the services that a customer will need while availing any of our services. This strategy resembles a 360 degree ecosystem and thus helps customers to get the best services at the most reasonable price. The goal of this entrepreneurship report is to analyse the importance of 360 degree business and how it is important for the customers in a country like Bangladesh. This report will also try to find out how such businesses can develop themselves while giving their services.Item Transfer learning based industrial steel plates fault diagnosis using industrial fault signals(BRAC University, 2021-09) Mizan, Mubasshira; Nilo, Laila Sumiya Khan; Tuli, Mosrika Momin; Uddin, Jia; Nahim, Nabuat ZamanTransfer learning (TL) has shown its great advantage to solve small-training-sample issues utilizing information learned from existing large data with deep learning tech- niques. Transfer learning has been e ectively applied in many deep learning net- works where su cient training samples are not accessible; it still experiences es- sential problems for image processing. Image processing technology has become an interesting eld in medics as image processing plays avital role in the discovery of the diseases in the early stages, which facilitates the treatment of these diseases. Image processing divides into numerous scopes. For case, image classi cation, image seg- mentation, image enhancement and image assessment. In this thesis, we will review the existing industrial fault diagnosis models and will propose an image-based deep learning model to detect or predict industrial faults. In order to do that we will convert 1D sensor's fault signals to 2D images. After that, we will extract deep fea- tures using a deep learning model for training and testing the classi er. To validate our model, we will use an industrial fault dataset. As programming tools, we will use Python and MATLAB.Item Synthesis and Antimicrobial Activities of Chromene Derivatives(Khulna University of Engineering & Technology (KUET), Khulna, Bangladesh, 2017-05) Islam, Md. Tarikul; Badal, Prof. Dr. Md. Mizanur RahmanThe design and synthesis of chalcone and chromene derivatives and their antibacterial activities were studied in this research. Conveniently, all products were synthesized from commercially available acetophenone, 4-hydroxybenzaldehyde and dimedone. Different synthetic strategies were used to obtain an easily accessible chromene scaffold with appropriate handles. At first, this research work was involved in an efficient procedure for the attachment of 4-hydroxybenzaldehyde and acetophenone in the presence of 10% NaOH to produce 3-(4-Hydroxy-phenyl)-1-phenyl-propenone. 4-{3-[(2,4-Dinitro-phenyl)-hydrazono]-3-phenyl-propenyl}-phenol phenylamine has been synthesized by the reaction of 2,4 dinitro phenyl hydrazine with chalcone. Reaction of dimedone with chalcone under refluxing condensation using dry benzene and zinc chloride as a catalyst to give the corresponding chromene derivative 4-(4-Hydroxy-phenyl)-7,7-dimethyl-2-phenyl-4,6,7,8-tetrahydro-chromen-5-one. This reaction also carried out by Microwave Irradiation and use ethanol as a solvent, without any catalyst. It was found that the preparation time for the compounds was reduced from 72 hours to 5-10 minutes during microwave irradiation. The structures of the all synthesized compounds were characterized by their IR, 1H NMR spectral data. The antibacterial and antifungal activity of the compounds was also investigated. The antimicrobial activity of the compounds at concentration 300 μg/disc was performed against three gram-positive bacteria (Bacillus cereus, Staphylococcus aureus and Listeria monocytogenes) and three gram-negative bacteria (Escherichia coli, Salmonella typhimurium, and citobacteria frundi) by Kirby-Bauer disc diffusion method using Ciprofloxacin as standard. Antifungal screening was carried out against one fungi (Tricodarma harzianum) using Michonazole as standard. Compound, I, 3-(4-Hydroxy-phenyl)-1-phenyl-propenone exhibits no activity against the tested bacterial strains Bacillus cereus, Listeria monocytogenes, Escherichia coli, Salmonella typhimurium, Citrobacter freundii, but showed moderate activity against the tested bacteria Staphylococcus aureus having inhibition zone 8 mm and also show antifungal activity aganist Trichoderma harzianum inhibition zone 10mm. Compound, II, 4-{3-[(2,4-Dinitro-phenyl)-hydrazono]-3-phenyl-propenyl}-phenol exhibits no activity against gram negative, gram positive strains but showed antifungal activity against Trichoderma harzianum inhibition zone 6 mm. Compound, III, 4-(4-Hydroxy-phenyl)-7,7-dimethyl-2-phenyl-4,6,7,8-tetrahydro-chromen-5-one showed activity against Gram positive, Gram negative except Listeria monocytogenes, Escherichia coli, Salmonella typhimurium. This compound, III also showed antifungal activity against Trichoderma harzianum inhibition zone 8 mm.Item Learning Agility Quotient and Work Readiness of Graduating Accounting Students: Embracing the Dynamics of IR4.0(Taylor & Francis Group, 2023-05-16) Azhara, Zubir; Jalaludin, Dayana; Erlane K. Ghani; Thurasamy, RamayahThis study examines if the learning agility quotient (LAQ) is an important determinant for the work readiness of graduating accounting students in the Fourth Industrial Revolution (IR4.0) environment. Using a questionnaire survey involving 275 respondents, we find that those with higher intelligence quotient (IQ) and emotional quotient (EQ) have higher LAQ. We also find that LAQ mediates the positive impact of IQ and EQ on their work readiness. Our findings implicate accounting education as they highlight the significant role of LAQ in relation to IQ, EQ, and work readiness. Further research is needed to determine if educational and work environment factors can effectively support and enhance learning agility.Item Valuation of rebar connection via mechanical coupler(Brac University, 2019-01-28) BUCG-ABC Joint Venture (BUCG-ABC JV)Item Industrial Effluent Treatment by Aeration and Filtration (Multimedia Filter)(Department of Civil and Environmental Engineering(CEE), Islamic University of Technology(IUT), Board Bazar, Gazipur-1704, Bangladesh, 2024-06-03) Ahmed, Taki Tahmid; Rahman, TasfiaTannery industries produces large amount of wastewater containing huge amount of pollutants that doesn’t satisfies the standard values of ECR. It should be treated before contaminating river water. This study focuses on treating tannery wastewater without using any chemical products. The Study aimed to reach Bangladesh guideline levels for industrial wastewater of which were pH(6-9),TS (2200mg/L), EC(1200 micro siemens per centimeter), DO (6mg/l), At first aeration and sedimentation was done of the wastewater for various retention times like 1 hour, 2 hours, 3 hours and so on. After completing aeration and sedimentation finally filtration was done using a multimedia filter which contains five layers of filter materials. These filter materials can reduce turbidity, color, total suspended solids etc. The main aim of this project is reducing the chemical oxygen demand (COD) value. These three steps process (aeration + sedimentation + filtration) resulted in 80-90% reduction in COD. Pollutant removal efficiency was measured in terms of total dissolved solids, total suspended solids, color, turbidity and COD. Dissolved oxygen level of the wastewater was increased due to aeration. Most values were found to achieve standard values.Item Aarong(BRAC University, 6/3/2015) Jahan, Mobasshera; Islam, Mohammad TamzidulThis report analyses the marketing strategies of the Aarong.

Shafiqul BariA field experiment was conducted in the char land of Gangachara Upazila under Rangpur district during July, 2019 to September, 2019 to evaluate the performance of Gima Kalmi under Mango and Gamari tree based agroforestry system influenced by different production systems and fertilizers application packages. The experiment was laid out in two factorial RCBD with 4 (four) replications. Factor A was three production systems viz. S1= Mango + Gima Kalmi, S2= Gamari + Gima Kalmi, S3= Gima Kalmi sole cropping and Factor B was four fertilizer and manure application packages viz. F0= No Fertilizer, F1= only cow-dung @ 10 t/ha, F2= only poultry manure @ 5 t/ha and F3= only chemical fertilizer as per Standard Recommendation Guide. The total numbers of experimental plots were 48. The result of the experiment revealed that plant height [30, 45, 60 and 75 DAS (Days after sowing)] as cm, number of leaves/plant (30, 45, 60 and 75 DAS), number of branches/plant (30, 45, 60 and 75 DAS), weight of fresh leaves/plant (30,45, 60 and 75 DAS) as gm, yield (30, 45, 60 and 75 DAS) as (t/ha) of Gima Kalmi significantly varied due to the different production systems and fertilizer applications when cultivated under the Mango and Gamari tree based agroforestry system in char land of Tista river basin. In case of main effects of different production systems, the maximum yield (9.08 t/ha) was recorded from Gima Kalmi sole cropping i.e. in treatment S3, whereas moderate yield (7.51 t/ha) was recorded from Mango + Gima Kalmi based agroforestry system i.e. in treatment S1. On the other hand, the minimum yield (3.82 t/ha) was recorded from Gamari + Gima Kalmi based agroforestry system i.e. in treatment S2. In case of main effects of fertilizer and manure applications, the highest yield (9.42 t/ha) was recorded from the plot where fully chemical fertilizer (F3) was applied whereas the lowest yield (3.71 t/ha) was obtained from the plot where no fertilizer (F0) was applied. Again, in case of interaction effects the maximum yield (10.54 t/ha) was recorded in the plot where Gima Kalmi was cultivated as sole cropping using only chemical fertilizer (S3F3) whereas the minimum yield (14.2 t/ha) was recorded in the plot where Gima Kalmi was cultivated at the floor of Gamari woodlot with no fertilizer (S2F0). From the economic analysis, it was found that the highest benefit-cost ratio (4.15) was recorded from Mango + Gima Kalmi based agroforestry system (S1) followed by Gamari + Gima Kalmi based agroforestry system (S2). On the other hand, the lowest benefit-cost ratio (2.93) was observed in Gima Kalmi sole cropping (S3). Finally, it may be concluded that Gima Kalmi can be cultivated successfully under newly established Mango and Gamari based agroforestry systems at the char land considering the additional returns as per investment in terms of money and time in the char land of Tista River Basin.
