| 2 | Design and analysis of high birefringence and nonlinearity with small confinement loss photonic crystal fiber显示文摘High birefringence with low confinement loss photonic crystal fiber (PCF) has significant advantages in the field of sensing, dispersion compensation devices, nonlinear applications, and polarization filter. In this report, two different models of PCFs are presented and compared. Both the models contain five air holes rings with combination of circular and elliptical air holes arrangement. Moreover, the elliptical shaped air holes polarization and the third ring air holes rotational angle are varied. To examine different guiding characteristics, finite element method (FEM) with perfectly matched layer (PML) absorbing boundary condition is applied from 1.2 to 1.8 |im wavelength range. High birefringence, low confinement loss, high nonlinearity, and moderate disper-sion values are successfully achieved in both the PCFs models. Numeric analysis shows that model-1 gives higher birefringence (2.75 ×10^-2) and negative dispersion (-540.67 ps/(nm ·km)) at 1.55 |im wavelength. However, model-2 gives more small confinement loss than model-1 at the same wavelength. In addition, the proposed design demonstrates the variation of rotation angle has great impact to enhance guiding properties especially the birefringence. | Rekha SAHA Md.Mahbub HOSSAIN Md.

| 3 | Preparation of bioactive glasses with controllable degradation behavior and their bioactive characterization显示文摘Bioactive glasses and ceramics have been widely investigated for bone repair because of their excel-lent bioactive characteristics. However, these biomaterials undergo incomplete conversion into a bone-like material, which severely limits their biomedical application. In this paper, borosilicate bioac-tive glasses were prepared by traditional melting process. The results showed that borosilicate glasses possessed high biocompatibility and bioactivity. In addition, when immersed in a 0.02 mol/L K2HPO4 solution, particles of a borate glass were fully converted to HA. The desirable conversion rate to HA may be achieved through the adjustment of the B2O3/SiO2 ratio. The results of XRD and FTIR analysis indicated that the degradation product was carbonate-substituted hydroxyapatite, which was similar to the inorganic component of bone. | YAO AiHua WANG DePing FU Qiang HUANG WenHai Mohamed N.

| 5 | Analysing the relationship between drought and soil erosion using vegetation health index and RUSLE models in Godavari middle sub-basin,India显示文摘Drought is a natural phenomenon posing severe implications for soil,groundwater and agricultural yield.It has been recognized as one of the most pervasive global change drivers to affect the soil.Soil being a weakly renewable resource takes a long time to form,but it takes no time to degrade.However,the response of soil to drought conditions as soil loss is not manifested in the existing literature.Thus,this study makes a concerted effort to analyze the relationship between drought conditions and soil erosion in the middle sub-basin of the Godavari River in India.MODIS remote sensing data was utilized for driving drought indices during 2000-2019.Firstly,we constricted Temperature condition index(TCI)and Vegetation Condition Index(VCI)from Land Surface Temperature(LST)and Enhanced Vegetation Index(EVI)derived from MODIS data.TCI and VCI were then integrated to determine the Vegetation Health Index(VHI).Revised Universal Soil Loss Equation(RUSLE)was utilized for estimating soil loss.The relationship between drought condition and vegetation was ascertained using the Pearson correlation.Most of the northern and southern watersheds experienced severe drought condition in the sub-basin during2000-2019.The mean frequency of the drought occurrence was 7.95 months.The average soil erosion in the sub-basin was estimated to be 9.88 t ha^(-1)year^(-1).A positive relationship was observed between drought indices and soil erosion values(r value being 0.35).However,wide variations were observed in the distribution of spatial correlation.Among various factors,the slope length and steepness were found to be the main drivers of soil erosion in the sub-basin.Thus,the study calls for policy measures to lessen the impact of drought and soil erosion. | Md Masroor Haroon Sajjad Sufia Rehman Roshani Singh Md Hibjur Rahaman Mehebub Sahana Raihan Ahmed Ram Avtar | 2022 | Geoscience Frontiers2022，13，2： | 4 |
| 6 | Effect of water regimes and organic matters on transport of arsenic in summer rice (Oryza sativa L.)显示文摘The arsenic contamination in soil-water-plant systems is a major concern of where, the groundwater is being contaminated with arsenic (above 0.01 mg/L) in the Indian subcontinent. The study was conducted with organic matter to find out the reducing effect on arsenic load to rice (cv. Khitish). It was observed that intermittent ponding reduced arsenic uptake (23.33% in root, 13.84% in shoot and 19.84% in leaf) at panicle initiation stage, instead of continuous ponding. A decreasing trend of arsenic accumulation (root > straw > husk > whole grain > milled grain) was observed in different plant parts at harvest. Combined applications of lathyrus + vermicompost + poultry manure reduced arsenic transport in plant parts (root, straw, husk, whole grains and milled grain) which was significantly at par (p > 0.05) with chopped rice straw (5 tons/ha ) + lathyrus green manuring (5 tons/ha) in comparison to control and corresponding soils. A significant negative correlation of arsenic with phosphorus (grain P with arsenic in different parts R 2 = 0.627-0.726 at p > 0.01) was observed. Similarly, soil arsenic had a negative correlation with soil available phosphorus (R 2 = 0.822 at p > 0.001) followed by soil nitrogen (R 2 = 0.762 at p > 0.01) and soil potassium (R 2 = 0.626 at p > 0.01). Hence, effective management of contaminated irrigation water along with organic matter could reduce the arsenic build up to plants and soil. | Sefaur Rahaman Ashim Chandra Sinha Dibyendu Mukhopadhyay | 2011 | Journal of Environmental Sciences2011，23，4： | 3 |
| 7 | Nutrient dynamics in the Sundarbans mangrove estuarine system of Bangladesh under different weather and tidal cycles显示文摘Introduction:Seasonal and tidal variations in nutrient concentration and water quality were investigated in the western Sundarbans of Bangladesh during the post-monsoon,winter and monsoon seasons during 2010–2011.Methods:Water collected from the surface,middle and bottom layers at six locations of the Kholpetua-Arpangashia river system during high and low tides was analyzed for temperature,salinity,pH,dissolved oxygen(DO),total dissolved solids(TDS),electrical conductivity(EC)and dissolved nutrients(NO3–N,PO4–P,SO4 and NH3–N).Results:The study revealed that nutrient concentrations were influenced by seasonal changes.Mean nutrient levels during post-monsoon,winter and monsoon seasons,respectively,were in the following ranges:nitrate(0.06–0.40,0.06–0.46 and 0.08–0.46 mg/L);phosphate(0.09–0.18,0.05–0.42 and 0.10–0.16 mg/L);sulphate(58.71–86.14,68.68–119.01 and 78.15–136.47 mg/L)and ammonia(0.02–0.08,0.02–0.04 and 0.26–0.38 mg/L).Increased levels of PO4–P,SO4 and NH3–N and lower DO and salinity were recorded during the monsoon period.Most of the experimental sites showed higher NO3–N content during monsoon,whereas few elevated concentrations were observed during post-monsoon and winter periods.High and low tidal waters contained mean nutrient levels in the following ranges:nitrate(0.05–0.46 and 0.04–0.40 mg/L);phosphate(0.05–0.42 and 0.07–0.18 mg/L);sulphate(63.63–125.36 and 58.71–136.47 mg/L)and ammonia(0.02–0.38 and 0.02–0.37 mg/L)without following any distinct fluctuation patterns.The western part of the Sundarbans receives less freshwater input during the monsoon season than other areas of the ecosystem,which reduces the variability of nutrient levels and water quality components.Conclusions:This study provides considerable advances in understanding the seasonality of nutrient distribution with possible tidal influence.The data generated from this study will guide continuing efforts to support a sound management for coastal mangrove ecosystems. | Shak Md Bazlur Rahaman Lipton Sarder Md Sayadur Rahaman Alokesh Kumar Ghosh Sudhin Kumar Biswas SM Shahjahan Siraj Khandaker Anisul Huq Abul Farah Md Hasanuzzaman Shikder Saiful Islam | 2013 | Ecological Processes2013，2，1： | 2 |
| 8 | Acanthus ilicifolius plant extract prevents DNA alterations in a transplantable Ehrlich ascites carcinoma-bearing murine model显示文摘AIM: To investigate the chemopreventive efficacy of the Indian medicinal plant Acanthus ilicifolius L Acanthaceae in a transplantable Ehrlich ascites carcinoma (EAC)- bearing murine model. METHODS: Male Swiss albino mice were divided into four groups: Group A was the untreated normal control; Group B was the EAC control mice group that received serial, intraperitoneal (ip) inoculations of rapidly proliferating 2 x 105 viable EAC cells in 0.2 mL of sterile phosphate buffered saline; Group C was the plant extract-treated group that received the aqueous leaf extract (ALE) of the plant at a dose of 2.5 mg/kg body weight by single ip injections, once daily for 10, 20 and 30 consecutive days following tumour inoculation (ALE control); and Group D was the EAC + ALE- treatment group. The chemopreventive potential of the ALE was evaluated in a murine model by studying various biological parameters and genotoxic markers, such as tumour cell count, mean survival of the animals, haematological indices, hepatocellular histology, immunohistochemical expression of liver metallothionein (MT) protein, sister-chromatid exchanges (SCEs), and DNA alterations.RESULTS: Treatment of the EAC-bearing mice with the ALE significantly (P < 0.001) reduced viable tumour cell count by 68.34% (228.7 x 106 ± 0.53) when compared to EAC control mice (72.4 x 106 ± 0.49), and restored body and organ weights almost to the normal values. ALE administration also increased (P < 0.001) mean survival of the hosts from 35 ± 3.46 d in EAC control mice to 83 ± 2.69 d in EAC + ALE-treated mice. Haematological indices also showed marked improvement with administration of ALE in EAC-bearing animals. There was a significant increase in RBC count (P < 0.001), hemoglobin percent (P < 0.001), and haematocrit value (P < 0.001) from 4.3 ± 0.12, 6.4 ± 0.93, and 17.63 ± 0.72 respectively in EAC control mice to 7.1 ± 0.13, 12.1 ± 0.77, and 30.23 ± 0.57 respectively in EAC + ALE-treated group, along with concurrent decrement (P < 0.001) in WBC count from 18.8 ± 0.54 in EAC control to 8.4 ± 0.71 in EAC + ALE. Furthermore, treatment with ALE substantially improved hepatocellular architecture and no noticeable neoplastic lesions or foci of cellular alteration were observed. Daily administration of the ALE was found to limit liver MT expression, an important marker of cell proliferation with concomitant reduction in MT immunoreactivity (62.25 ± 2.58 vs 86.24 ± 5.69, P < 0.01). ALE was also potentially effective in reducing (P < 0.001) the frequency of SCEs from 14.94 ± 2.14 in EAC control to 5.12 ± 1.16 in EAC + ALE-treated group. Finally, in comparison to the EAC control, ALE was able to suppress in vivo DNA damage by abating the generations of ‘tailed’ DNA by 53.59% (98.65 ± 2.31 vs 45.06 ± 1.14, P < 0.001), and DNA single-strand breaks (SSBs) by 38.53% (3.14 ± 0.31 vs 1.93 ± 0.23, P < 0.01) in EAC-bearing murine liver. CONCLUSION: Our data indicate that, ALE is beneficial in restoring haematological and hepatic histological profiles and in lengthening the survival of the animals against the proliferation of ascites tumour in vivo. Finally, the chemopreventive efficacy of the ALE is manifested in limiting MT expression and in preventing DNA alterations in murine liver. The promising results of this study suggest further investigation into the chemopreventive mechanisms of the medicinal plant A. ilicifolius in vivo and in vitro. | Tridib Chakraborty Dipak Bhuniya Mary Chatterjee Mosiur Rahaman Dipak Singha Baidya Nath Chatterjee Subrata Datta Ajay Rana Kartick Samanta Sunil Srivastawa Sankar K Maitra Malay Chatterjee | 2007 | World Journal of Gastroenterology2007，13，48： | 2 |
