BACKGROUND: Arsenic (As)-contaminated groundwater used for long-term irrigation has emerged as a serious problem by adding As to soils. Phytoremediation potential of fiber crops viz., kenaf (Hibiscus cannabinus L.), mesta (Hibiscus sabdariffa L.), and jute (Corchorus capsularis L.) was studied to clean up As-contaminated soil.METHODS AND RESULTS: Varieties of three fiber crops were selected in this study. Seeds of kenaf, mesta, and jute varieties were germinated in As-contaminated soil. Uptake of As by shoot was significantly higher than that by root in the contaminated soil. In As-contaminated soil, kenaf and mesta varieties accumulated more As, than did jute varieties. In the plant parts above ground, mainly the shoots, the highest As absorption was recorded in kenaf cv. HC-3, followed by kenaf cv. HC-95. Kenaf varieties produced more biomass. In terms of higher plant biomass production, and As absorption, kenaf varieties showed considerable potential to remediate As-contaminated soil.CONCLUSION: The overall As absorption and phytoremediation potentiality of plant varieties were in the order of kenaf cv. HC-3 > kenaf cv. HC-95 > mesta cv. Samu-93 > jute cv. CVE-3 > jute cv. BJC-7370. All varieties of kenaf, mesta, and jute could be considered for an appropriate green plant-based remediation technology in As-contaminated soil.

Comparative Proton Transfer Efficiencies of Hydronium and Hydroxide in Aqueous Solution: Proton Transfer vs Brownian Motion

Uddin, Nizam,Kim, Jeongmin,Sung, Bong June,Choi, Tae Hoon,Choi, Cheol Ho,Kang, Heon American Chemical Society 2014 The Journal of physical chemistry B Vol.118 No.47

<P>With the help of QM/EFP-MD with modern correlated quantum theories, distinctly different proton transport dynamics for hydronium and hydroxide ions was revealed. The efficiency of proton transfer for hydronium was found to be significantly higher than that for hydroxide, and the difference in efficiency increased as the temperature was lowered. This difference in dynamics suggests that molecular Brownian diffusion may play an important role in hydroxide transport. Our theoretical findings are consistent with recent experimental observations of proton transfer in amorphous solid water.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/jpcbfk/2014/jpcbfk.2014.118.issue-47/jp5093114/production/images/medium/jp-2014-093114_0009.gif'></P>

Comparative Atomic Charges on Na+-(H2O)n (n = 1–6) Clusters

Nizam Uddin,최철호 대한화학회 2015 Bulletin of the Korean Chemical Society Vol.36 No.3

The performance of our mean gradient charge (MGC) concept was systematically investigated by adopting Na+-(H2O)n (n = 1–6) model clusters. The Mulliken charges are sensitive to the choice of theories and basis sets, and ChelpG charges abnormally behave with the system size. MGC and “atoms-in-molecules” (AIM) show small mean standard deviations (~0.02) with the choice of the theory and the basis set. However, an unpredictable value was found in AIM predictions. Both natural population analysis (NPA) and MGC yielded smooth and monotonic curves as a function of the system size. Therefore, MGC appears to have desirable properties in the consistent and reliable predictions of atomic charges.

Life table parameters of an indigenous strain of Neoseiulus californicus McGregor (Acari: Phytoseiidae) when fed Tetranychus urticae Koch (Acari: Tetranychidae)

Md. Nizam Uddin,Md. Zinnatul ALAM,Md. Ramiz Uddin MIAH,Md. Ismail Hossain MIAN,Kishowar-E- MUSTARIN 한국곤충학회 2017 Entomological Research Vol.47 No.2

The life table of the indigenous Neoseiulus californicus was studied at different temperatures and 65 ± 5% relative humidity under conditions of 16 h light : 8 h dark (LD 16:8). The total developmental period from egg to adult varied from 3.0 to 14.0 days at 15 to 35°C. Survival to adulthood ranges from 86.21 to 93.94%, with the highest rate at 25°C. The lower threshold temperature from egg to adult stages of females and males was 10.84 and 10.72°C, respectively, and the thermal constant was 57.14 degree‐days (DD) for females and 56.18 DD for males. Total number of eggs laid by each female was the highest (70.38 eggs) at 25°C, whereas average daily fecundity was the highest (3.69 eggs/female/day) at 30°C. The net reproductive rate was the highest (48.49) at 25°C and lowest (26.18) at 30°C. Mean generation time decreased from 19.04 to 11.47 days with increasing temperature from 20 to 30°C. Both intrinsic rate of natural increase (0.284) and finite rate of increase (1.32) were maximum at 30°C. Adult longevity was the highest (42.75 days for females and 32.60 days for males) at 20°C and lowest (22.70 days for females and 15.30 days for males) at 30°C. Sex ratio was female biased and was the highest (78.08) at 25°C and lowest (70.24) at 30°C. Developmental data of five constant temperatures, temperature thresholds and thermal requirements may be used to predict the occurrence, number of generations and population dynamics of N. californicus as an important biocontrol agent of Tetranychus urticae.

Antifilarial potential of the root extracts of Mirabilis jalapa Linn. (Nyctaginaceae) on cattle filarial parasite Setaria cervi

Uddin, Qamar,Parveen, N.,Khan, Nizam U.,Zaidi, SM Kashif R.,Singhal, KC. Kyung Hee Oriental Medicine Research Center 2003 Oriental pharmacy and experimental medicine Vol.3 No.4

Effect of aqueous and alcoholic extracts of the roots of Mirabilis jalapa Linn. Four Oclock plant, on the spontaneous movements of both the whole worm and the nerve-muscle (n.m.) preparation of Setaria cervi and on the survival of microfilariae in vitro was studied. Alcoholic extract caused the inhibition of spontaneous movements of the whole worm and the n.m. preparation of S. cervi, whereas aqueous extract caused inhibition of spontaneous movements of the n.m. preparation. The initial stimulatory effect was not observed by aqueous and alcoholic extracts on n.m. preparation while effect of alcoholic extract on the whole worm was characterized by an increase in the amplitude of contractions followed by reversible paralysis. The concentrations required to inhibit the movements of the whole worm and n.m. preparation for alcoholic extract of root were $270\;{\mu}g/mL$ and $40\;{\mu}g/mL$, respectively whereas an aqueous extract caused inhibition of n.m. preparation at $30\;{\mu}g/mL$ suggesting a cuticular permeability barrier. Alcoholic extract of the roots of M. jalapa caused concentration related effect on the survival of microfilariae of S. cervi. The $LC_{50}$ and $LC_{90}$ for alcoholic extract as observed after 6 hrs. were found to be 10 ng/mL and 18 ng/mL., respectively.

Enhancement of antimicrobial properties of shoe lining leather using chitosan in leather finishing

Mahmud, Yead,Uddin, Nizam,Acter, Thamina,Uddin, Md. Minhaz,Chowdhury, A.M. Sarwaruddin,Bari, Md. Latiful,Mustafa, Ahmad Ismail,Shamsuddin, Sayed Md. Techno-Press 2020 Advances in materials research Vol.9 No.3

In this study, a chitosan based coating method was developed and applied on the shoe lining leather surface for evaluating its inhibition to bacterial and fungal attacks. At first, chitosan was prepared from raw prawn shells and then the prepared chitosan solution was applied onto the leather surface. Secondly, the characterization of the prepared chitosan and chitosan treated leather was performed by solubility test, ATR-FTIR, XRD pattern, SEM and TGA. Evaluation of antimicrobial efficacy of chitosan was assessed against two gram positive, two gram negative bacteria and a reputed fungi by agar diffusion test. The results of this study demonstrated that chitosan took place in both the surface of collagen fibres and inside the collagen matrix of crust leather. The chitosan showed strong antimicrobial activities against all the tested microorganisms and the inhibition increased with increasing percentage of chitosan. Therefore, the prepared chitosan in this study can be an environment friendly biocide, which functions simultaneously against different spoilage bacteria and fungi on the finished leather surface. Thus by using the prepared chitosan in shoe lining leather, the possibility of microbial attack during shoe wearing can be minimized which is one of the important hygienic requirements of footwear.
