Since 194os, Mount Uludag （Bithynian Olympus） has been considered famous with winter sports center in Turkey. In addition, it is one of the rare places because of its plant diversity and is also one of the important plant areas of Turkey. The ski run constructions are rapidly increased in the past decades in the alpine and subalpine belts of the mountain. Rate of nitrogen mineralization and some properties of soft were investigated in the soils of the three ski runs and undisturbed neighborhood forest sites. These ski runs are at the upper part of the forest belt in the mountain. Abies bornmuelleriana forest community is the postclimax and very sensitive to destruetion. The rates of the nitrogen mineralization in the soils were determined in controlled conditions （60% water-holding capacity, 20℃）. Nitrification and nitrogen mineralization were in the ski run inside where the natural recovery started, increased compared with the outside of the ski runs. Waterholding capacity, organic carbon, and total nitrogen were decreased in the massive damaged ski run, and due to these changes, the rates of mineralization and nitrification were also decreased.

化石能源的枯竭及全球环境问题的加剧使得社会对可再生能源的需求逐渐增加。在诸多可再生能源中,生物油的价格较低且在全球分布较为均匀,发展前景较好。通过热解技术,可以将生物质转化为生物油,可以进一步通过催化精制转化为液体燃料。其中,从木质纤维制备液体燃料最具前景的技术是催化加氢脱氧(HDO)。本研究中,首先通过蒸氨法合成了一系列不同比例的Ni Cu/Si O催化剂,该催化剂具有独特的层状硅酸镍结构。之后,以苯酚为模型化合物,探究了催化剂中Ni:Cu比以及还原温度对催化剂加氢脱氧活性的影响。借助X射线衍射(XRD),傅里叶变换红外光谱(FT-IR)以及透射电镜(TEM)表征,对上述影响的原因进行了探究。结果表明,相比于700 ℃,催化剂较低的还原温度400 ℃下还原之后可以保留较多的硅酸镍,进而提供了较多的酸位点,有利于提高苯酚的脱氧率,环己烷的最高选择性可达84%。且Ni Cu合金的形成也是该催化剂具有较高活性的重要原因,在不同比例的Ni Cu催化剂中,NiCu/Si O在苯酚加氢脱氧反应中的活性最高。在上述研究基础上,以月桂酸为甘油三酯基生物油的模型化合物,研究了其对苯酚加氢脱氧的影响。当月桂酸加入量为0.2g时,环己烷选择性最高,为79.4%。结果表明,月桂酸的添加量对苯酚的脱氧程度有较大影响。较少的月桂酸添加量有助于提高苯酚脱氧程度,而当月桂酸添加量过多时,环己醇脱水生成环己烷的反应会受到抑制,从而降低了苯酚的脱氧率。

The large-scale development of wind power is an important means to reduce greenhouse gas emissions, alleviate environmental pollution and improve the utilization rate of renewable energy. At the same time, large-scale non grid connected wind power generation theory avoids the technical difficulties of wind power integration [1]. However, due to the randomness and uncontrollability of wind energy, the output power of the wind power generation system will fluctuate accordingly [2]. Therefore, the corresponding energy storage devices are arranged in the non-grid-connected wind power generation system to ensure the power quality, and it has become the key to full utilization of renewable energy. In the case of wind speed fluctuation, the DC bus control strategy of the wind turbine is proposed in this paper. It can reduce the impact on the unit converter and the power load;this ensures safe and stable operation of non-grid connected wind turbines.

A ship＇s crew plays an important role in the maritime transportation sector and their performance is paramont in the shipping industry. On this account, an impartial evaluation of the crew＇s performance is an important issue. In this paper, the ship officer＇s performance evaluation problem is studied. The performance evaluation criteria that shipping companies take into account are determined and a performance evaluation process is modelled by using the FAHP （Fuzzy Analytic Hierarchy Process） based on Chang＇s Algorithm. Linguistic variables and fuzzy numbers are used in the assessment process. The results of the proposed model demonstrate that the FAHP method is effective and helps managers make better and more reliable decisions under fuzzy circumstances.

钙钛矿太阳能电池（PSC）由于其作为一种高效和低成本技术近年来快速发展,目前有机无机杂化的钙钛矿太阳电池转换效率（PCE）超过25%。高效、低成本的钙钛矿太阳能电池（PSC）是下一代光伏技术有希望的候选者,对科学界也产生了重大影响。与有机无机杂化钙钛矿（OIHP）相比,全无机钙钛矿（AIP）具有更强耐热性的优势,尽管它仍然落后于OIHP-PSC的效率。AIP-PSC的研究领域不断扩大,在短短几年内取得了 PCE超过20%的巨大进步。本文总结了当前可用的可扩展沉积技术,包括喷涂、槽模涂层、刮刀、喷墨印刷和真空/气相沉积方法。在减少材料/溶液浪费、在大面积上更均匀的薄膜涂层以及更好的薄膜形态控制方面,这些技术比旋涂方法更具吸引力。为实现商业化,钙钛矿太阳电池的成本、效率和稳定性都是重要的考虑因素。然而,许多研究都专注于钙钛矿电池的效率和寿命,钙钛矿的成本受到的关注较少。这项工作根据已发表的文章中提供的OIHP-PSC和AIP-PSC的结构、材料和效率分别计算了相应模块的材料成本;基于设计的100MW钙钛矿太阳电池组件的生产线,计算了投资成本并对比了在不同国家生产OIHP-PSC和AIP-PSC的间接费用。基于最高效的OIHP-PSC和最高效的AIP-PSC计算了两种模块的预期制造成本分别为29美分/瓦特和39美分/瓦特,并比较了在不同国家生产的差异性。最后考虑到组件的效率与实验室目前报道的最高效率将具有一定的差距,我们讨论了在合理的效率区间两种组件的成本-效率学习曲线,结果表明OIHP-PSC的组件制备价格总体低于AIP-PSC。

Introduction: Juvenile idiopathic arthritis (JIA) represents a heterogeneous group of childhood chronic arthritic conditions. The pathogenesis of JIA remains incompletely understood. This disease can lead to a significant morbidity including joint deformity, growth impairment and a persistence of active arthritis into adulthood. The past two decades have witnessed significant advances in treatment and improved outcomes for affected children. With the current use of biologics, more target-specific, better tolerated, safer and more effective treatments have become possible. However, continuing, comprehensive follow-up is needed to characterize the long-term effects of such treatments. Hyperimmunoglobulin E syndrome (hyper-IgE, or Job’s syndrome) is a rare immune deficiency characterized by high IgE levels, atopic chronic eczema, tendency towards re-current pyogenic infection, neutrophil chemotaxis disorder and varying T-cell function impairment. Case Report: The case of a 17-year-old male patient with hyper-IgE who develops the oligoarticular subtype of JIA over a period of four years is discussed. The course of JIA is unfavorable, causing severe deformity of numerous joints (left elbow, right 3rd metacarpophalangeal, left knee, right ankle) and a fungal infection scar on the left eye. Blood tests show an ESR of 89 mm/h, rheumatoid factor (RF) 8.3 IU/mL (0 - 20) and positive antinuclear antibody (ANA). To improve gait, corrective surgery is performed on the right ankle, followed by rehabilitation and physical therapy. Conclusion: Developments in the near future will be crucial for understanding JIA pathophysiology and improving treatment.
