This study involves the addition of poly(allylamine) (PAA) with chitosan (CS) for facilitated CO2 transport. Detailed characterizations of the membranes including advance microscopic analysis, thermal stability, stiffness, etc. were investigated. The CO2 separation studies from binary gas mixture indicated the superior CO2 permeance and CO2/N2 selectivity of the PAA30 (70 wt% CS + 30 wt% PAA) membrane at 90 °C and feed absolute pressure of 2 bar. Further, CO2 separation performance of PAA30 was gauged under varying conditions. The performance above the Robeson upper bound plot, displayed the potential of the PAA30 membrane for industrial flue gas separation.

Plant height is one of the most important agronomic traits in crop breeding because dwarf and semidwarf cultivars are resistant to lodging and have led to remarkable yield increases in cereal crops. Although several genes related to gibberellins signaling or biosynthesis resulting in dwarfism have been isolated, however, lots of causal genes controlling dwarfism remain to be uncovered. We characterized a dwarf mutant (ID13) in rice. The mutant displayed several altered phenotypes compared to the wild type, such as reduced plant height, increased tiller number, short and rounded leaf tips, presence of a yellowish stripe on the leaf blade, late and asynchronous heading, strong root systems, short erect panicle, smaller seed size, etc. The dwarfism of the mutant was responsive to gibberellic acid (GA), based on the analyses of two GAmediated processes. Anatomical observations revealed that the mutant plants had fewer vascular bundles and reduced cell size compared with wild type plants. Genetic analysis indicated that the dwarf mutant was controlled by a single recessive gene, d13, which was flanked by two STS markers, DMR-3 and S5789, within the physical distance of 265 kb around the centromeric region on chromosome 9. Cloning and functional analysis is in progress.

The architecture of rice panicle is primarily determined by the arrangement of branches and spikelets, and it directly affects grain yield. We identified a mutant for panicle apical abortion from a japonica cultivar Hwacheongbyeo treated with N-methyl-N-nitrosourea. Under normal growth conditions, the mutant had multiple abnormal phenotypes, such as a slight reduction in plant height, narrow and dark green leaf blades, and small erect panicles with clear panicle apical abortion compared to the wild-type plants. Genetic analysis revealed that the panicle apical abortion was controlled by a single recessive gene, which is tentatively designated as paa. The paa gene was fine mapped at an interval of 71 kb flanked by STS markers aptn3 and S6685-1 at the long arm of chromosome 4. Sequence analysis of the candidate genes within the delimited region showed a single base-pair change corresponding to an amino acid substitution from glycine to glutamic acid. We expect that the paa gene will be a clue to uncover the molecular mechanism of panicle apical abortion and to maintain the panicle identity for grain yield in rice breeding programs.

Abbavaram, Babul Reddy A.,Reddyvari, Hymavathi R.V. Korean Chemical Society 2013 대한화학회지 Vol.57 No.6
A convenient synthesis of bifunctional sulfonamide-amide derivatives was reported. Amide coupling of 4-methyl benzoic acid 1 followed by reaction with chlorosulfonic acid produce ethyl-4-(3-(chlorosulfonyl)-4-methylbenzoyl)piperazine-1-carboxylate 4. The resulted compound on further treatment with various anilines produces the title sulfonamide-amide derivatives 5a-n. The configurations of these compounds were established by elemental analysis, IR, $^1H$ NMR, mass spectra, and by their preparation from the corresponding 4-methyl benzoic acid 1 and chlorosulfonic acid. All these new compounds demonstrate significant in vitro antibacterial and antifungal activities against all bacterial and fungal strains.

Single nucleotide polymorphisms (SNPs) are the most abundant variation in plant genomes. As DNA markers, SNPs are rapidly replacing simple sequence repeats (SSRs) and sequence tagged sites (STSs) markers, because SNPs are more abundant, stable, easy to automation, efficient, and increasingly cost-effective. We developed a 96-plex indica/japonica SNP genotyping set for genetic analysis and molecular breeding in rice using Fluidigm platform. Informative SNPs for indica/japonica populations were selected from 1536 Illumina SNPs and 44K Affymetrix SNP chip data of Rice Diversity and our resequencing data sets. Selected SNPs were evenly distributed across 12 chromosomes and average physical distance between adjacent SNP markers was 4.38Mb. We conducted genetic diversity analysis of 49 Bangladesh germplasm and check varieties to test a 96-plex indica/japonica SNP genotyping set we developed. High-throughput Fluidigm SNP genotyping system will serve a more efficient and valuable tool for genetic diversity analysis, DNA fingerprinting, quantitative trait locus (QTL) mapping and background selection for crosses between indica and japonica in rice.

Approaching a linear programming model for production planning of a ready-made garments industry
Sayma Suraiya,Md. Babul Hasan 한국전산응용수학회 2023 Journal of applied mathematics & informatics Vol.41 No.1
The ready-made garments (RMG) have been making a crucial contribution about of $81$ \% of total export and $12.36$ \% of total GDP of the country which is now the single biggest export earner for Bangladesh. The cheap production cost is the key important factor to explore this RMG sector. But these RMG sector is running on the basis of intuition based decisions. Though they are making profit it is not optimal. In this study, a deterministic model is developed to help the RMG to minimize the production cost and to maximize their profit along with optimal utilization of available resources. 10 different types of products are taken from one of the garments factories of Gazipur, Dhaka to prepare this research work. This model suggests the manufacturer on which products along with how much should be produced to meet the future demand by maintaining the lowest production cost that ultimately maximize the profit of the organization, and also helps Bangladesh to compete in the international market with ‘Made in Bangladesh’. LINDO programming is used here to solve this LP model.

The cytotoxic dosage of exposed drug waste is frequently discharging on aquatic surfaces via wastewatertreatment plants and pharma industries. Early detection of these drug wastes with a reliable and accurateare in great need. In this report, a noble metal effectively doped on oxidized one-dimensional (1D) singlewalledcarbon nanotube and abundant oxygen functional groups presenting two-dimensional (2D) grapheneoxide on its surface, and hydrophobic cavities are the promising selector towards electrochemicaloxidation of Naproxen (NPZ). A hybrid nanocomposite Au@f-CNT/GO was engineered by the ultrasoundassistsonication method and employed for the ultra-quantification of the therapeutic drug NPZ. In addition,various physicochemical and analytical techniques were utilized to confirm the successful formationof composite and principal detection of NPZ. Au@f-CNT/GO fabricated glassy carbon electrode exhibits alow resistance and higher electrocatalytic activity toward NPZ sensing. In addition, under the optimizedcondition, the sensor demonstrates an acceptable linear range of 100 nM 15.6 mM, a lower limit ofdetection of 14 nM (S/N = 3), and higher sensitivity of 1.7484 lA lM 1 cm2. Furthermore, the proposedsensor has high selectivity, stability, reproducibility, and repeatability. Moreover, real sample analysisshows appreciable recovery results of 96 to 99% which strongly suggests that the proposed sensor haspotential applicability for the sensitive detection of NPZ in the various water and biological samples.

Understanding the morphological and physiological characteristics which are attributable to determine indica and japonica subspecies of Asian rice (Oryza sativa L.) is important to conceive breeding strategy. However, information of quantitative trait loci (QTLs) associated with targeted traits related to subspecies domestication and differentiation-related traits remains limited. Two reciprocal F2 mapping populations generated from a cross between Ilpumbyeo (japonica) and Dasanbyeo (indica) were developed and used for constructing genetic maps to identify QTLs responsible for subspecies specific-related traits using 107 sequence-tagged site (STS) markers. A total of 26 main-effect QTLs for subspecies-related traits such as grain length, grain width, grain length-width ratio, apiculus hair length, and potassium chlorate resistance, were detected on seven chromosomes (1, 2, 3, 4, 5, 6, and 8). Of the detected QTLs, 14 QTLs corresponding to the previously reported QTLs suggesting the functional conservation of QTLs across populations and the remaining 12 QTLs appeared to be novel QTLs. A total of 29 significant epistatic QTLs were also detected in present study demonstrating an important genetic basis of epistatic interactions for complex subspecies-related traits. These results suggest that the subspecies-related traits and detected QTLs should be taken into consideration to incorporate with marker-assisted selection strategy in rice breeding program.
