有必要了解在羔羊皮前处理过程中发生的变化，因为这将影响最终成革的质量。胶原类型、胶原的宏观和微观结构、非胶原蛋白的存在、糖蛋白的类型和数量都对成革的质量有很大影响。在对皮加工工艺进行根本修正时，了解皮结构的变化对成革质量的影响非常重要。例如，在前期加工阶段，用酶代替化学品将导致皮组成的不同，而这将影响成革的质量。用原子力显微镜和光学显微镜观察传统硫化物、浸灰脱毛或酶脱毛处理后的皮粒面层，用二维电泳分析存在的蛋白质。结果表明，皮表面的纤维结构、与皮下层的结构非常不同，酶脱毛方法处理后的表皮层有一种高分子量的蛋白，而酶脱毛加工的没有。将这些技术获得的结果与传统皮革的化学、物理和感官性能联系在一起，阐述了皮的少量组分与成革性能的关系，并为开发酶加工体系提供了支持。运用这些知识，我们已经能够生产加工的羔羊皮革，其性能等同或优于传统皮革。

了解羔羊皮在初期加工过程中发生的变化很有必要,因为这些变化会影响皮革产品的最终品质。胶原的种类及其宏观与微观结构,除胶原外其他蛋白质的存在,蛋白多糖的数量和种类,都对皮革质量有着深远的影响。用二维凝胶电泳和质谱分析,从未经处理的原皮和浸酸皮(用硫化钠和石灰处理,酶软化,再用氯化钠与硫酸保存的皮)中分离出的蛋白质具有明显的区别。用含有敏感着色程序的琼脂糖凝胶电泳,来鉴定存在于未经处理和处理过的皮中的氨基葡聚糖以及它们对皮革质量的影响。结果显示,有效去除作为胶原原纤维间黏接剂的蛋白多糖可以提高皮革的质量。这些分子的去除,不仅打开了皮的纤维结构,同时对脱出羊毛也很重要。赋予原皮弹性的弹性蛋白,对制革具有重大意义。定量分析弹性蛋白中的锁链(赖氨)素和异锁链(赖氨)素,可以评估弹性蛋白在皮革质量中的作用。

Agricultural productivity is affected by air temperature and CO2 concentration. The relationships among grain yields of dry season irrigated rice (Boro) varieties (BRRI dhan28, BRRI dhan29 and BRRI dhan58) with increased temperatures and CO2 concentrations were investigated for futuristic crop management in six regions of Bangladesh using CEREs-Rice model (DssATv4.6). Maximum and minimum temperature increase rates considered were 0°C, +1°C, +2°C, +3°C and +4°C and CO2 concentrations were ambient (380), 421, 538, 670 and 936 ppm. At ambient temperature and CO2 concentration, attainable grain yields varied from 6506 to 8076 kg·ha-1 depending on rice varieties. In general, grain yield reduction would be the highest (13% - 23%) if temperature rises by 4°C and growth duration reduction would be 23 - 33 days. Grain yield reductions with 1°C, 2°C and 3°C rise in temperature are likely to be compensated by increased CO2 levels of 421, 538 and 670 ppm, respectively. In future, the highest reduction in grain yield and growth duration would be in cooler region and the least in warmer saline region of the country. Appropriate adaptive techniques like shifting in planting dates, water and nitrogen fertilizer management would be needed to overcome climate change impacts on rice production.

Background: Distal protection devices are increasingly used to prevent emboliz ation during percutaneous coronary interventions(PCI) in saphenous vein grafts(s VG) and native coronary arteries(NV). During interventions with the Filterwire d evice we have observed reduced flow that is reversible following removal of the filter(filter no reflow, FNR), which might be erroneously interpreted as true no reflow and might be associated with reduced capture efficiency of the basket. M ethods: We analyzed the incidence of FNR in 58 patients(60 lesions) at high risk of embolization undergoing PCI of either a sVG or a NV using the Filterwire(Bos ton scientific, Natick, MA). Qualitative and quantitative angiographic analysis was performed, and the volume of collected debris was estimated using a photogra phic technique. Results: In our population, about 1/3 of the cases showed FNR, w hich was associated with angiographically visible filling defects within the bas ket, indicating macroembolism. However some patients (especially those undergoing vein graft interventions) showed filling defects without FNR, and some others FNR without filling defects. Thus we tried to under stand the predictors of FNR: FNR was associated with higher amount of collected debris(36.97±42.98 mm3 vs. 11.31±18.47 mm3, p=0.005), was neither prevented by abciximab, nor predicted by high thrombotic burden, increasing stent volume or need for predilatation. When patient with and without angiographically evident m acroembolisation were separately analyzed, a linear correlation of FNR with the quantity of debris was only apparent in the macroembolization group. Conclusions : Interventionalists should be aware of the “Filter No Reflow”, a common but r eversible angiographic complication when the Filterwire device is used. Reduced flow seen during these procedures should be treated conservatively. Mechanical o bstruction of the filter, but also other mechanisms(pharmacologically active deb ris? platelet aggrega

Climate change impacts are visible in Bangladesh which requires adoption of judicious crop management practices for sustainable agriculture. Crop simulation models are effective in this regard and can be used for optimizing water and nitrogen inputs for maximization of wheat yields. Two field studies were conducted at Bangladesh Agricultural Research Institute (BARI) for evaluating the effect of increased temperature on wheat production under variable water and N rates, through the use of DssAT v4.6 model. Thirty years historic weather data and BARI Gom-26 wheat-cultivar coefficients, as generated through use of GLUE of DssAT model, were used for evaluating the impact of temperature rise with variable rates of irrigation water and nitrogen. The effects of four levels of nitrogen (0, 40, 80 and 120 kg ha-1) and four irrigation levels [0 (no irrigation), 1, 2 and 3] on wheat yield were evaluated under 0°C, 1°C, 2°C and 3°C rise in temperature. simulation results indicated that wheat yield increased with increase in nitrogen application rate, but decreased with the temperature rise. Crop growing duration was reduced by about five days for each degree rise in temperature, irrespective of levels of irrigation water and nitrogen-rates. In general, there was yield reduction of 8.13, 16.77 and 24.97 % with increased temperature of 1°C, 2°C and 3°C, respectively, when compared with no temperature rise treatment. For interaction of temperature rise-N dose, the magnitude of yield decline under temperature rise was higher with increased dose of N. Agronomic N use efficiency at different N rates and temperature rise level were calculated. N use efficiency decreases with the increase in temperature rise and the highest (29.95 kg grain kg-1 N) was obtained from 40 kg N ha-1 treated plot with 0°C temperature rise i.e. existing atmospheric temperature. simulation results indicated increase in wheat yield with higher levels of irrigation water, and int

Maize is an emerging important crop in Bangladesh because of its high yield potential and economic profitability compared to rice and wheat crops. There is a need to understand the growth and yield behavior of this crop in varying production environments of Bangladesh. Crop model such as Decision support system For Agro-technology Transfer (DssAT) version 4.6 (DssAT hereafter) can be utilized cost effectively to study the performances of maize under different production environments. It needs to calibrate and validate DssAT model for commonly cultivated maize cultivars in Bangladesh and subsequently take the model to various applications, including inputs and agronomic management options and climate change that impacts analyses. so, the present study was undertaken to firstly calibrate DssAT model for popular four hybrid maize cultivars (BARI Hybrid Maize-7, BARI Hybrid Maize-9, Pioneer 30B07 and NK-40). subsequently, it proceeded with the validation with independent field data sets for evaluating their growth performances. The genetic coefficients for these cultivars were evaluated by using Genotype coefficient calculator (GENCALC) and Generalized likelihood uncertainty estimation (GLUE) module of DssAT on the basis of first season experiment. The performance of the model was satisfactory and within the significant limits. After calibration, the model was tested for its performance through validation procedure by using second season data. The model performed satisfactorily through phenology, biomass, leaf area index (LAI) and grain yield. Phenology, as estimated through days to flower initiation and maturity, was in good agreement, although simulated results were slightly over predicted compared to observed values but within the statistical significance limit...when compared with observed values at specific growth stages of the crop. The final yield values (10.12 to 10.59 t·ha-1) were in close agreement with the observed values (10.16 to 10.94 t·ha-1), as the perce
