作者： m.ham.ad Naeem shahid m. shahid Ibni Zamir Ihtisham-Ul Haq m. Kamran Khan mazhar Hussain Usman Afzal m. Asim Ihtisham Ali Department of Agronomy University of Agriculture Faisalabad Pakistan

A field study to evaluate the impact of different tillage regimes and nitrogen levels on yield and yield components of maize (Zea mays L.), was conducted during autumn 2014 at Students Farm, Department of Agronomy, University of Agriculture, Faisalabad. The experiment was laid out in RCBD (Randomized Complete Block Design), with split plot arrangement having three replications. The experiment was comprised of three tillage regimes (minimum, Conventional and Deep) and three nitrogen levels viz: 100, 200 and 300 kg•ha-1. Urea was used as a source of nitrogen, sulphate of potash as a source of potassium and triple super phosphate as a source of phosphorous. The amount of phosphorous and potash was constant in all the treatments i.e. 125 kg•ha-1 and 100 kg•ha-1 respectively. Results of present study are summarized as yield parameters are significantly affected by different nitrogen levels and tillage regimes. maximum number of plants at harvest (7.93), number of grain rows per cob (17.70), number of grains per row (34.31), number of grains per cob (678.58), and cob weight (187.50 g) were observed in deep tillage at 200 kg•ha-1 nitrogen application. 1000-grain weight (275.52 g), biological yield (15.66 t•ha-1), grain yield (6.16 t•ha-1) and dried stalk yield (9.91 t•ha-1) were observed maximum in deep tillage at 200 kg•ha-1 nitrogen application. Harvest index significantly affected by tillage regimes and maximum harvest index (39.58%) were recorded in deep tillage which was statistically at par with conventional tillage (38.83%). It was concluded that higher grain yield of maize can be obtained by deep tillage with the application of 200 kg•ha-1 nitrogen application under the prevailing conditions of Faisalabad.

Purpose: Our study aimed to investigate the effects of Ramadan fasting on cognitive and physiological function in a group of healthy muslim subjects. methods: We measured demographic, physiological (blood pressure), and cognitive function including attention switching task (AST) and delayed matching to sample (DmS) using the Cambridge Neuropsychological Test Automated Battery (CANTAB) at two periods of the study (before Ramadan, at the second week in Ramadan) in 15 subjects. Results: During fasting, performance on the AST test improved significantly for switching cost (p = 0.030) and for congruent condition of AST task (p = 0.043), for diastolic pressure decreased (p = 0.069) in healthy subjects. There was no significant effect for incongruent condition and number of errors and percent to complete task for DmS test and systolic blood pressure. Conclusions: The results suggest that Ramadan fasting is associated with significant changes in cognition, and causes a drop in diastolic blood pressure in healthy subject.

铁镓(FeGa)薄膜与其它软磁材料相比具有较大的磁致伸缩常数,在设计集成磁性传感器芯片中具有独特的优势,可通过采用非磁性掺杂和多层膜方法来控制这种合金薄膜的磁学与电学性能参数。在掺杂一定量硼(B)元素后,厚度小于30 nm的FeGa薄膜顽力可以得到显著降低,而对于较厚薄膜在插入超薄Al_2O_3中间层后软磁性能可以得到同样程度显著改善,同时饱和磁化(m_s)变化可忽略。对于我们制备的FeGaB(25 nm)/Al_2O_3(0.5 nm)/FeGaB(25 nm)多层膜,其易轴矫顽力可以小到0.98×79.6 A/m,电阻率与50 nm单层FeGaB膜相比增加了1.5倍,同时具有吉赫兹高磁导率谱。样品微结构分析表明,磁性颗粒结晶质量和物理尺寸的减小对软磁性改善起到重要作用,另外也讨论分析了静磁相互作用和表面形貌对磁畴运动及矫顽力的影响。所发展的掺杂与多层膜混合方案来增强电磁性能的方法,也可应用于其他类型的软磁材料系统。
