Starting to Sail
lent, considered by many to be one of the best sailing areas in the country, provided an opportunity not to be missed.

The first dinghy I shared was with three other equally inexperienced friends. We bought a 14 foot fibre glass family dinghy through Exchange ...
متن کاملInvestigation of sailing yacht aerodynamics using real time pressure and sail shape measurements at full scale
The steady and unsteady aerodynamic behaviour of a sailing yacht is investigated in this work by using full-scale testing on a Stewart 34. The aerodynamic forces developed by the yacht in real time are derived from knowledge of the differential pressures across the sails and the sail shape. Experimental results are compared with numerical computation and good agreement was found.
متن کاملSunilkumar MN: Sail Sign www.jrmds.in
A sail-like, triangular projection from the mediastinum in chest radiographs is encountered in healthy children in the first few years of life. This has been proved to be the shadow of the thymus and is not of pathological significance. As it resembles a “sail” it is known as the thymic Sail Sign (SS). Literature review reported it is seen in about 10% of normal children. Interestingly many tre...
متن کاملLarge Area Sail Design Concepts
Mission concepts to several hundred AU and beyond are under study at NASA Marshall Space Flight Center (MSFC) and NASA Jet Propulsion Laboratory (JPL). The preliminary results of these mission studies have identified solar sails as one of the promising propulsion technologies for making these ambitious precursor and interstellar missions a reality. This paper presents solar and beamed energy sa...
متن کاملEversion endarterectomy under full prasugrel treatment
The third-generation thienopyridine prasugrel has much stronger antiplatelet effect compared to other current antiplatelet inhibitors and exhibits practically zero resistance in healthy people. Prasugrel is used as a pre- and post-treatment in percutaneous coronary or neurovascular interventions with parallel aspirin regime. However, as there is a higher reported bleeding with intraluminal inte...
