High Winds at Nyg?rdsfjell

Bacterial Inoculation and Co-Inoculation Improves Durum Wheat Productivity in Alkaline Calcareous Soils

作者： muhammad Bilal Yngve Birkelund Matthew Homola Department of Physics and Technology at the Arctic University of norway (Uit) Department of Engineering and Safety at the Arctic University of norway (Uit) nordkraft Vind

Wind energy in cold climate offers challenges that include among others, the icing on the turbine blades that affects the power output of the turbines. We investigate the presence of high winds at the nyg?rdsfjell wind farm that is situated in north of the Arctic Circle in norway. The data is taken from three 2.3 MW Siemens wind turbines(SWT-2.3-93) that were installed at nyg?rdsfjell during the fall of 2005. There are total of 185 high winds events detected consisting of 1737 hours during the observation period May 2008 until April 2009. Out of these 1737 hours of high winds, 269 hours occurred during May2008 until October 2008 and 1468 hours occurred during november 2008 until April 2009 that is 84.5% of total high winds hours. That shows the majority of high winds events occurring during the colder periods. The ten leading high winds events showed the presence of wind speeds ranging from 16 m/s to 19 m/s with maximum up to 24 m/s. The analysis established the existence of high winds at nyg?rdsfjell during colder times.

最后断路器保护主要用于防止逆变站交流系统甩负荷所引起的严重过电压对系统设备造成的不良影响。除了常规型的最后断路器保护,特高压换流站还配置有避雷器型最后断路器保护作为后备保护。但是,此类保护还存在对过电压水平无法实现动作速度的适应性的问题。针对现有基于固有电压量积分方法存在的缺陷,提出了基于电压实时测量量的避雷器型最后断路器保护改进方法,并提出了基于电压–能量反比特性的避雷器型最后断路器保护动作门槛值的动态整定策略。该文参照向家坝—上海特高压直流输电系统实际参数搭建仿真模型,并通过仿真算例验证了该文方法在保证动作可靠性的前提下,可以进一步缩短系统设备承受高倍过电压的时间,更好地保护主设备。

Purpose: To analyse, and compare using finite element analysis, the biomechanical properties of the 1.7 mm miniplate fixation against 2 conventional fixation techniques (2.0 mm bi-cortical screws and 2.0 mm miniplate) used in the mandibular sagittal split osteotomy. Methods: A 3-D virtual mandible model was constructed using images from CT scan. Sagittal split osteotomy was carried out virtually, and the fixation techniques were applied onto the model. 9 virtual models consisted of the 3 fixation techniques with mandibular movements of 3 mm setback, 3 mm advancement and 7 mm advancement were developed. Bite forces of 50, 75 and 100 n were applied for incisor bite simulation and 100, 200 and 300 n for molar biting force. Finite element analysis was carried out in Solidworks, and readings of stresses and displacement were recorded. Wilcoxon rank sum test was applied and P-value of 0.05 was set for statistical analysis. Results: In this manuscript the authors have compared 3 internal fixation techniques in mandibular sagittal split osteotomy. There was a statistically significant difference for both stress and displacement readings between the 1.7 mm miniplate, the 2.0 mm bi-cortical screws and the 2.0 mm miniplate for all mandibular movements. For the 1.7 mm miniplate vs 2.0 mm bi-cortical screws, the stress reading was (P = 3.063e-08, W = 314), and for displacement was (P = 5.811e-05, W = 282). For the 1.7 mm miniplate vs 2.0 mm miniplate, the stress reading was (P = 9.862e-4, W = 263) and for displacement was (2.05e-2, W = 235). Conclusion: The 1.7 mm miniplate has adequate strength to be used in mandibular sagittal split osteotomy, although statistically less rigid when compared to the conventional 2.0 mm miniplate and 2.0 mm bi-cortical screws, especially in larger movements.

Purpose:Plate fixation is the gold standard for the treatment of displaced forearm shaft fractures in adults. Conventionally radial shaft fractures will be plated either on the volar surface or on the dorsal surface depending on which approach has been chosen. The lateral surface of the radius provides an even and uniformly curved area for placing a plate. It has the advantage of restoring and easy assessing the radial bow after surgery. We designed a prospective study to observe the outcome of lateral plating of radius shaft ***:nineteen patients were included in this study performed in Government Medical College, Jammu, India. Among them, 13 had fractures of both the forearm bones and 6 had isolated radial shaft fracture. Three patients had Galeazzi fracture dislocation. Fixation was done within 36 h of injury in all using 3.5 mm limited contact dynamic compression plate or locking compression plate applied to the lateral surface of the radius. Ulna was fixed in routine ***:Union was achieved in 18 out of 19 patients, after a mean time of 17.44 weeks. According to Anderson et al.'s criteria, 12 patients had excellent results, 5 had satisfactory and 1 had unsatisfactory result. There was one failure (nonunion).Conclusion:The outcomes including rate of union were comparable to those in the existing literature. Plating the radial shaft on the lateral surface is a viable alternative to volar or dorsal plating of the radius. Larger studies with randomized data are needed to assess whether it has any superiority over other existing techniques.

The “X Well” is located in the Salawati Basin which is part of Western Papua. The interval of study is the Klasaman Formation that is characterized by thick sediment intercalated sandstones and shales. The movement of Sorong Fault strongly controlled the sedimentation of this formation. This study is very important to give a contribution for developing exploration prospect by predicting reservoir distribution since localized facies change may mark the distribution of sandstones. The current study aims: 1) to define the age of Klasaman Formation;2) to define the vertical facies;3) to define the sequence stratigraphy;and 4) to predict the lateral change of facies. Five nannofossil datum planes are found throughout the interval and cover the age Late Miocene to Early Pliocene. LO Sphenolithus abies points the age 3.65 Ma, LO Reticulofenestra pseudoumbilicus points the age 3.79 Ma, FO Pseudoemiliania lacunosa points the age 4 Ma, LO Discoaster quinqueramus and LO Discoaster berrgrenii point the age 5.59 Ma and Top of small Reticulofenestra Interval points the age 7.167 Ma. They define the nn11 up to nn16 Martini’s zonation. The age of Klasaman Formation is known as the uppermost Late Miocene to the Early Pliocene. Four facies can be identified, namely Upper Shoreface, Lower Shoreface, Offshore Transition and Offshore. The upper shoreface facies is characterized by thick and clean sandstones, about 2.41 - 20.64 meters thick, while the lower shoreface facies consists of predominantly very fine to fine-grained sandstones intercalated by siltstones and claystones. The offshore transition facies is marked by thick claystones and siltstones intercalated with thin sandstones, whilst the offshore facies is marked by thick laminated claystones. nine Parasequences 4th order can be identified within study interval, namely Progradational Parasequence-1 to 2, Retrogradational Parasequence-3, Progradational Parasequence-4 to 6, Retrogradational Parasequence-7 to 9. They are bounded b
