Cruise shipping: Problems and prospects from blue economy perspectives
(American Institute of Physics Inc., 2020-07-23) Chawdhury, D.,; Islam, M.A.
The demand for cruise shipping has progressively developed over the centuries in EU countries and Americas region. In the recent years, it has steadily multiplied attractiveness amongst vacationers in Asia especially in the countries of South East Asia and the Far East. The wave of cruise tourism has also touched Bangladesh, which has ample scope and opportunity to improve this promising sector. The fast growth of river and ocean cruise and geographic expansion has amplified the traveling involvedness rising the financial, socio-economic, ecological and cultural impacts. Consequently, the significance of cruise improvement must be evaluated on how it marks initially to society in a travel destination. It is a descriptive investigation and the study was grounded on together primary and secondary sources to study consequences, which would highlight on the following features: instituting a 24X7 visitor service point, ensuring a wide-ranging logistic facilities associated with cruise tourism, welcoming overseas cruise line operators to scrutinize exceptional sights in Bangladesh, collaborating with other Asian nations, forming a distinctive management division, along with development and emerging exclusive resources related with the travel and tourism sector of Bangladesh.
Cruise tourism: A new aspiration for Bangladesh tourism industry
(American Institute of Physics Inc., 2020-07-23) Chawdhury, D.; Islam, M.A.
Globally, Cruise tourism is recognized as one of the most vigorous and rapidly growing components of the travel and tourism industry. In the whole tourism market, the growth of the international cruise industry is significant. Despite the international economic fall, the cruise market is still developing. With a long and attractive coast, virgin and mangrove forests and beautiful islands, gorgeous ancient and ethnic heritage, maybe a magnificent destination of the tourists for cruise tourists of Bangladesh. Bangladesh's economy is now developing at a steady pace; the number of middle-class population and their possessing disposal earnings are increasing, which can be expended on travel and tourism activities. In 2017, February-March an international boat ship took a round trip through Bangladesh with about 135 foreign tourists visited the Sundarbans, the largest mangrove forest and Maheshkhali Island in Cox's Bazar that made about 35 lakh foreign revenue. Although this market is the most mature one in different countries, it is new in the aspect of Bangladesh. Therefore, the government has to address the opportunity and challenges in the cruise shipping industry seriously and has to be taken proactive measures in improving the cruise sector which can unswervingly impact the economy of Bangladesh
Deep Neural Network-Based Approach to Identify the Paddy Leaf Disease using ResNet50-V2
(Elsevier, 2023-10-21) Islam, M.A.; Rahman, M.M.; Shohan, A.A.; Pulok, R.A.; Akter, S.; Ahmed, M.T.
South Asian countries especially Bangladesh, India, and Srilanka are very involved in paddy cultivation. In Bangladesh and India, one of the key producing crops is paddy. Worldwide more than 40 percent of the world's population derives most of its calories from rice and traditionally farmers are directly involved production of rice. But every year lot of farmers have to face a tremendous amount of loss due to paddy leaf disease. Major of the farmers do not know how to identify perfectly in the primary stage that's why they are facing loss. Due to the increase in population, it is very important to make paddy cultivation scientific and produce more. There are more than 30 types of paddy leaf disease and from there in Bangladesh, approximately 10 types of disease are quite similar. If it is possible to ensure the leaf disease in the very primary stage within a very short time, then every farmer can reduce their loss. Nowadays many researchers are interested in identifying paddy leaf disease using modern science. In this paper, we worked on paddy leaf disease detection and it has worked on 4 types of disease and 1 healthy and without any disease leaf class of paddy. This paper through an automated detection approach using deep learning techniques achieved the highest accuracy instead of the previous applicable working model and traditional manual disease detection process. In this paper, we have analyzed it using 4 different types of models. ResNet50-V2, Inception-V3, MobileNet-V2, and DensNet-201 algorithm models have been applied here and the finding of the research is, that all the models achieved more than 95% accuracy from these ResNet50-V2 has achieved the best accuracy and it is 99.06%. We hope that these deep learning models and techniques will detect the disease with high accuracy in the very beginning time and it will help reduce damage and loss of paddy cultivation. © 2023 IEEE.

Effect of Acceptor Concentration on Performance of CdTe Solar Cell from Numerical Analysis
(IEEE, 2016-10-28) Noman, M.A.A.; M.S., Islam; Abden, M.J.; Arifuzzaman, M.; Islam, M.A.
In this study, the absorber layer of Cadmium Telluride (CdTe) ultra-thin solar cell was analyzed by using the one dimensional simulator Analysis of Microelectronic and Photonic Structures (AMPS 1D) software. A novel structure of ultra-thin CdS:O/CdTe solar cell is suggested in this research that emphases on conversion efficiency. The maximum conversion efficiency of ~ 26.24% (JSC = 27.05 mA/cm2, VOC = 1.2 V, FF = 0.886) is achieved with 600 nm CdTe absorber layer at the acceptor concentration of 5 × 1019 cm-3. The temperature effect is also examined with an aim to realize the environmental impact on performance of the cell. Our outcomes offer innovative research guidelines for resolving persistent challenges of CdTe photovoltaics.

A study was conducted :It the functional molecular chemistry laboratory of Kagawa Univcrvity to find out the effect of some plant extracts as a growth inhibitor during March 2017 to August 2017. Four common plant IC3"cs (Eucalyptus. Jamun. Mahogany and Cannon ball tree). which were collected from l3ongladcsh. were extracted and their efficacy was tested using four different plant species. Among the test species. cress was the mOM sensitive. whereas leuuce, Italian ryegrass and rice sccdlmgs showed almost similar inhibitory activity on shoot and root growth.

Kinetics and Thermodynamics of Silk Dyeing with Turmeric Extract
(AATCC, 2018-05-01) Naser, Abu; Haque, Md. Ahsanul; Farzana, Nawshin; Smriti, Shamima akter; Islam, M.A.
A kinetics and thermodynamics study of turmeric extract dyeing on Bombyx mori silk fabric was conducted with 1 g/L initialdye concentration at three temperatures (70 °C, 85 °C, and 100 °C). The fabric was pre-mordanted with FeSO4 and dyed with the turmeric extract at pH 7 and a material liquor ratio (MLR) of 1:20. Pseudo first-order and pseudo second-order kinetics were tested. The adsorption kinetics of turmeric extract dyeing on silk fit the pseudo second-order kinetic model. The activation energy was 94.9 kJ/mol. The enthalpy and entropy of activation were 91.93 kJ/mol and –14.47 J/mol∙K, respectively. © 2018, American Association of Textile Chemists and Colorists. All rights reserved.

Mathmatical formulations of the basic diffusion equation: a discussion
(BRAC University, 2004) Islam, M.A.; Buschatz, H.
A discussion is made on the possible forms of mathematical formulations for the basic diffusion equation. The formulations have been derived from the law of motion. It is shown that the assumption of Stokes resistance leads to paradoxical conclusions in some specific cases of diffusion processes. It is argued that the expression for resistant forces in transport processes is empirical, and hence the form of the diffusion equation depends on the expression chosen in describing the resistant forces. Evidences are collected from literature in favor of both thermodynamic and Fickian formulation of the diffusion equation. It is concluded that ideal form of diffusion equation is absent, and the choice of the form of diffusion equation would depend on the specific circumstances being studied.
