Crop nutrition has a significant effect on disease incidence, resistance or tolerance of various crops. There is currently a lack of reliable recent UK-based research about the effect of copper, zinc and boron on disease incidence, green leaf area （GLA）, green leaf retention （GLR） and grain yield of winter wheat, spring wheat and spring barley. Data analysis showed that these trace elements had positive effects on GLR. These positive effects may have been due to the role of copper, zinc and boron in the production of defence related compounds （phenolics and lignin）, which may have reduced the disease incidence resulting in prolonged GLR. Grain yield was significantly enhanced by the application of these trace elements on the crop grown on high pH calcareous soil, which can be partly attributed to enhanced GLR. Also trace elements have a positive role in reproductive growth, flowering and male fertility. On average, zinc was found to be the most consistent trace element in terms of enhancing GLR and grain yield. Across all trials, it was noted that for every 10% increase in GLA from trace elements, grain yields increased by 4.2% in 2012-2013, by 4.4% in 2013-2014 in winter wheat and by 3.9% in spring wheat in 2014. These are remarkably consistent and indicate that increasing GLA by 10% by early dough stage was associated with a yield improvement of about 4%. These trace elements also had a positive effect on grain protein content （GPC）. This research concluded that the trace elements had positive effects in enhancing GLA and yield. It can be speculated that with the use of these trace elements, there may be more scope for using less robust or reduced rates of fungicides to control foliar diseases, which may help to maximize farm profits.

The International Committee of Medical Journal Editors （ICMJE） believes that there is an ethical obligation to responsibly share data generated by interventional clinical trials because participants have put themselves at risk. In a growing consensus, many funders around the world - foundations, government agencies, and industry - now mandate data sharing. Here, we outline ICMJE＇s proposed requirements to help meet this obligation. We encourage feedback on the proposed requirements. Anyone can provide feedback at www. *** by April 18, 2016.

医生表现的评定现已成为世界范围内临床医师所关注的事实，它包括用一系列标准化指标，对医疗保健质量进行评定和监测。有关医疗保健质量中的缺陷——即在知与行间的差距已有很多文献记载。在与社会性别、种族和社会经济状况相关的可及性、质量及结局等方面，同样也存在着这种不平等的现象并也有所记载。由于对不合乎标准或存在差异的服务质量的认识，对医护人员的公众责任感和卫生系统的改进提出了迫切的要求。

Mineral element compositions of Baobab fruit and seed have been determined using Instrumental Neutron Activation Analysis. Total of 18mineral elements were determined of which 10 are not normally reported using other methods. The concentrations of heavy metals were: Arsenic < 0.06 and < 0.04, Mercury < 0.04 and < 0.04 Hg and Cadmium < 0.08 and < 0.04 respectively for the seeds and the fruit. The average concentration of trace elements in the seed were;Aluminium (11.50 μg/g), Barium (17.3 μg/g), Bromine (2.45 μg/g), Cobalt (0.07 μg/g), Copper (28.6 μg/g), Iron (<42 μg/g), Iodine (<0.04 μg/g), Manganese (17.7 μg/g), Sodium (23.53 μg/g), Vanadium (0.035 μg/g), and Zinc (12.06 μg/g), while the average concentrations of Aluminium (27.74 μg/g), Barium (13.10 μg/g), Bromine (3.01 μg/g), Cobalt (0.08 μg/g), Copper (14.9 μg/g), Iron (26.05 μg/g), Iodine (0.27 μg/g), Manganese (7.05 μg/g), Sodium (52.06 μg/g), Vanadium (0.08 μg/g), and Zinc (0.79 μg/g) were determined for the dried fruit pulp. The mineral concentrations of the baobab fruit and seed were characterized with high concentration of potassium, calcium, magnesium and substantive amount of chlorine [K (21350 μg/g), Ca (3170 μg/g), Mg (2310 μg/g) and Cl (211 μg/g), for the fruit pulp and K (12240 μg/g), Ca (2360 μg/g), Mg (4720 μg/g) and Cl (88.6 μg/g), for the seed]. The fruits and seeds present useful source of mineral needs for the indigenous African community where the trees are found and may be recommended as food supplement due to high content of calcium, magnesium and potassium.
