Simulation of fire impact on forest floor renewal in pine forests was based on predictions for 2100 by the Canadian Climate Centre for increase in temperatures of by4.5℃and total precipitation by 14%in the West Siberian pre-forest-steppes and empirical regression relationships between them and the degree of burnt forest floor,as well as amount of Pinus sylvestris *** was predicted that by 2100,pine regeneration on fire prone sites under the canopy of the dominant forest type will increase by 29-54%compared to the 1980 s but on adjacent open sites,regeneration will decrease twice as *** means that the regeneration potential and pine population stability in pre-forest-steppes will become as poor as it is today.

Interconnected microspheres of V2Os composed of ultra-long nanobelts are synthesized in an environmental friendly way by adopting a conventional anodization process combined with annealing. The synthesis process is simple and low-cost because it does not require any additional chemicals or reagents. Commercial fish-water is used as an electrolyte medium to anodize vanadium foil for the first time. Electron microscopy investigation reveals that each belt consists of numerous nanofibers with free space between them. Therefore, this novel nanostructure demonstrates many outstanding features during electrochemical operation. This structure prevents self-aggregation of active materials and fully utilizes the advantage of active materials by maintaining a large effective contact area between active materials, conductive additives, and electrolyte, which is a key challenge for most nanomaterials. The electrodes exhibit promising electrochemical performance with a stable discharge capacity of 227 mAh·g^-1 at 1C after 200 cycles. The rate capability of the electrode is outstanding, and the obtained capacity is as high as 278 at 0.5C, 259 at 1C, 240 at 2C, 206 at 5C, and 166 mAh·g^-1 at 10C. Overall this novel structure could be one of the most favorable nanostructures of vanadium oxide-based cathodes for Li-ion batteries.

A low cost service robot was designed and implemented specifically to be used in service industries e.g. hotels. This service robot can deliver a requested payload (towels, bed-sheets, drinks or toiletries) to a customer. As evident with modern technology, robots are assisting man in several avenues of the service industry. This designed service robot can propose an error free service, work around the clock and consume less time with requested tasks. The prototype can handle two commands received from two different rooms simultaneously. It has the ability to choose to always deliver to the closest room from its base first. Also, it has the function to carry two different types of payloads in two of its compartments and to lift up the desired payload ordered by the customer using a scissor lift system. The service robot also uses a touch screen to interact with the customer. The algorithm of the design ensures that the payload will always be delivered to the right customer in due time.

Recent evidence is leading to the replacement of vitamin K antagonists, the efficacy of which in preventing stroke in patients with atrial fibrillation (AF) is well established, with better tolerated and more manageable new anticoagulant drugs, with a lower risk of intracranial bleeding, no clear interactions with food, fewer interactions with medications, and no need for frequent laboratory monitoring and dose adjustments. Among new anticoagulants, dabigatran etexilate is a direct, competitive inhibitor of thrombin. It was evaluated for patients with AF in the RE-LY trial, showing lower rates of stroke and systemic embolism at a dose of 150 mg twice daily with similar rates of major hemorrhage compared with warfarin; and non inferiority compared with warfarin for the prevention of stroke and systemic embolism at a dose of 110 mg twice daily, with lower rates of major bleeding. Beside dabigatran, oral factor X a inhibitors are also emerging for the prevention of thromboembolic events in AF. Despite the obvious advantages of these new oral anticoagulants over vitamin K antagonists, further information is still needed on how to prioritize the patients deriving the greatest benefit from these novel agents on the basis of patient characteristics or drug pharmacokinetics. There is also a need for assessing their long-term efficacy and safety over decades in the real-world setting.
