Polyethene is a global environmental threat, whereas jute (Corchorus spp.) fber is biodegradable, eco-friendly and can be used as a substitute for polyethene. Jute is a short-day plant and cultivated in March to July in Indian subcontinent for bast fber production. This season-bound cultivation nature hampers continuous supply of bast fber in the industry. In addition, its long cultivation period creates difculties to accommodate other high-value crops. To address these issues, a short life span (early fowering) jute genotype is extremely felt in jute growing areas of the world. But, unfortunately such variety has not been developed yet through both conventional and biotechnological approach. Accordingly, we adopted chemical mutagenesis by establishing LD50 (Lethal Dose) of EMS (Ethyl Methane Sulfonate) at 150 mM with 4h’ incubation for Capsularis jute seed. A novel mutant was found named—Komola, which showed a shorter lifespan than its ancestor by fowering at 70 days instead of 120 days. In addition, the mutant's stem and petiole was coppery-red instead of green. Molecular analysis revealed four SNPs in PMIR1 (Plastid Movement Impaired 1 Related 1) and two clade deletions in ELF3 (Early Flowering 3) genes from stable M4 generation. Histochemical and biochemical analyses explained this genotype’s lower content of lignin. This mutant could be used as future breeding material for the development of year-round cultivable jute genotype along with ofer up accommodation of other high-value agricultural crops in cropping pattern with a good source of year-round supply of bast fber to the industry

( M. Y. Arafat ),( A. S. M. Khairuddin ),( R. Paramesran ) 한국인터넷정보학회 2018 KSII Transactions on Internet and Information Syst Vol.12 No.11

Vehicular license plate (LP) recognition system has risen as a significant field of research recently because various explorations are currently being conducted by the researchers to cope with the challenges of LPs which include different illumination and angular situations. This research focused on restricted conditions such as using image of only one vehicle, stationary background, no angular adjustment of the skewed images. A real time vehicular LP recognition scheme is proposed for the skewed images for detection, segmentation and recognition of LP. In this research, a polar co-ordinate transformation procedure is implemented to adjust the skewed vehicular images. Besides that, window scanning procedure is utilized for the candidate localization that is based on the texture characteristics of the image. Then, connected component analysis (CCA) is implemented to the binary image for character segmentation where the pixels get connected in an eight-point neighbourhood process. Finally, optical character recognition is implemented for the recognition of the characters. For measuring the performance of this experiment, 300 skewed images of different illumination conditions with various tilt angles have been tested. The results show that proposed method able to achieve accuracy of 96.3% in localizing, 95.4% in segmenting and 94.2% in recognizing the LPs with an average localization time of 0.52s.

A fast and selective method for cadmium(II) removal from water by procaine hydrochloride (PQ+ Cl )immobilized polyurethane foam (PUFs) sorbent was developed. The method was based upon formationof [CdI4] 2aq in the test aqueous KI solution and subsequent extraction by PQ+ Cl treated PUFs. Thesorption of Cd2+ ions followed first order equation with an overall rate constant of 0.132 0.033 min 1. The values of DH and DS were 41.54 0.9 kJ mol 1 and 144.58 3.1 J mol 1 K 1, respectively with acorrelation factor of 0.998. The thermodynamic parameters (DH, DS and DG) suggest that the sorption wasspontaneous and exothermic process. The negative value of DS provides indication of moderate sorption of[CdI4]2 ion associate and ordering of the ionic charges without compensatory disordering of the sorbedspecies onto the sorbent. Cadmium(II) sorption is mainly dominated by absorption related to ‘‘solventextraction’’ and an added component for ‘‘surface adsorption’’. PQ+ Cl treated PUFs packed column was alsotested for preconcentration of trace concentrations of cadmium(II) species in various water samples. Theretained Cd species were successfully recovered with dilute HNO3 (1.0 mol L 1) and subsequently analyzedby ICP–OES. Thus, the proposed sorbent packed column provides efficient removal of traces of cadmium(II)ions from water samples. The method could be extended for preconcentrate of trace and ultra trace cadmiumspecies from large samples onto PUF packed column and subsequently analyzed. Indeed, the developedmethod could be satisfactorily applied to the determination of trace Cd ions in natural water.

Different types of milk products, such as kwacha golla, mawa, cheese, curd, and chocolate are popular in Bangladesh. However, the microbiological safety of these products is poorly understood. This study was performed to assess the microbiological quality of kwacha golla, a local milk product. Kwacha golla samples were collected from ten different areas of Rajshahi and Kushtia regions, and the quality of the each sample was assessed using various parameters including standard plate count, total coliform, fecal coliform, total fungi, and spore-forming bacteria, as well as food-borne microorganisms. Out of 300 samples, total coliform was detected at 56.66% (n= 300), exceeding the minimum allowable limit of 36.66%. Similarly, experiments were carried out with fungi and food-borne pathogens including Escherichia coli, Listeria monocytogenes, Salmonella sp., and Staphylococcus aureus. Results revealed 85.33, 53, and 49.33% of the samples were contaminated by fungi, E. coli, and L. monocytogenes, respectively. However, all samples showed no contaminations of Salmonella sp. and Staphylococcus sp. Therefore, this study could be helpful to the people of Bangladesh by providing information on the possibility of a major health problem caused by the consumption of kwacha golla.
