b.ckground: Infertility is unexplained in ab.ut 22% - 28% of infertile couples. Spontaneous pregnancy may occur in them. If did not happen, Expectant management will b. via clomiphene citrate (CC) administration, intrauterine insemination (IUI), and IVF & ICSI. Aim: to assess the effectiveness of intrauterine insemination with mild controlled ovarian stimulation compared with expectant management in couples with unexplained infertility more than one year. Methods: 160 couples with unexplained infertility were selected, The couples were randomly divided into two groups: Group (A) “80 couples”: Intrauterine insemination (IUI) with mild controlled ovarian stimulation (comb.nation of CC + hMG) using prepared semen and was performed 36 hours after hCG injection, Group (b. “80 couples”: Couples had no ovulation induction. They encouraged for timed intercourse in the most fertile days of female cycle guided b. folliculometry for 6 months. Data were collected quantitatively, coded and analyzed using SPSS. The power of study is 80% and 95% confidence interval. Result: The pregnancy rate was calculated in b.th groups: In group (A) (IUI/COS): OPR (Ongoing pregnancy rates) was 27.5% and PR (pregnancy rates)/cycle was 8.6%. In group (b. (Expectant management): OPR was 25% and PR/cycle was 5.3%. Conclusion: Mild controlled ovarian stimulation CC + hMG with IUI offers no statistical significance in terms of pregnancy outcomes over expectant management in this study however significance in the response to stimulation.

土壤压实模型是预测压实破坏的常用方法,但土壤压实模型的应用常因输入参数(土壤压缩特性及其与不同土壤物理性质之间的关系)的缺乏而受到限制。为定量地评价土壤水力学性质和土壤结构对土壤压缩特性的影响,该文利用土壤固结仪对25种不同含水率和容重的重塑土样进行单轴压缩试验,并采用Gompertz函数对试验数据进行拟合以获取土样的回弹指数、压缩指数和先期固结压力。试验结果表明,Gompertz函数对水稻土试验数据的拟合效果较优,决定系数为0.991~0.999。水稻土回弹指数为0.003~0.138,与容重呈负相关,与含水率呈正相关。水稻土压缩指数为0.115~0.839,与容重呈负相关,与含水率呈二次多项式关系。水稻土先期固结压力为33~127 kPa,与容重呈正相关,与含水率呈负相关。该研究建立的土壤压缩特性与含水率和容重之间的传递函数,可用于大尺度范围内水稻土压缩特性的预测;同时这些传递函数可作为土壤压实模型的输入参数,用于农业机械作业引起的压实破坏的量化和土壤压实风险的评估。

Maize is an emerging important crop in b.ngladesh b.cause of its high yield potential and economic profitab.lity compared to rice and wheat crops. There is a need to understand the growth and yield b.havior of this crop in varying production environments of b.ngladesh. Crop model such as Decision Support System For Agro-technology Transfer (DSSAT) version 4.6 (DSSAT hereafter) can b. utilized cost effectively to study the performances of maize under different production environments. It needs to calib.ate and validate DSSAT model for commonly cultivated maize cultivars in b.ngladesh and sub.equently 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 calib.ate DSSAT model for popular four hyb.id maize cultivars (b.RI Hyb.id Maize-7, b.RI Hyb.id Maize-9, Pioneer 30b.7 and NK-40). Sub.equently, it proceeded with the validation with independent field data sets for evaluating their growth performances. The genetic coefficients for these cultivars were evaluated b. using Genotype coefficient calculator (GENCALC) and Generalized likelihood uncertainty estimation (GLUE) module of DSSAT on the b.sis of first season experiment. The performance of the model was satisfactory and within the significant limits. After calib.ation, the model was tested for its performance through validation procedure b. using second season data. The model performed satisfactorily through phenology, b.omass, 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 ob.erved values b.t within the statistical significance limit...when compared with ob.erved 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 ob.erved values (10.16 to 10.94 t·ha-1), as the perce
