Take the Trunk Road exit and turn left onto Trunk Rd. GETTING THERE: From Anchorage, take the Glenn Highway north towards Wasilla. The area is called Quggesh, which means swan. The area is also the location of a former Dena’ina village site and holds cultural significance. A trail to the north takes you on a 1-mile upland loop through a beautiful birch forest, with more views from the bluff out into the Refuge. A trail to the south takes you down a boardwalk and out to the viewing platform at Swan Lake where you’ll get views of the Palmer Hay Flats and the Chugach Mountains in the distance. If you’ve enjoyed the Wasilla Creek Boardwalk & Trail, you’ll love visiting Swan Lake. This spring, the access to Swan Lake was finalized, GLT and Fish & Game staff built a connector trail out to the road, and the Swan Lake Boardwalk & Trail are now open to the public! The nearby Wasilla Creek Boardwalk & Trail opened in 2016, while we waited on opening the Swan Lake Boardwalk & Trail until the adjacent housing development was completed. Next GLT raised money to build wetland boardwalks out into the Refuge from two different trailheads, providing stunning and never before seen views and access to fishing and wildlife watching spots. In 2014, Great Land Trust raised $1.5 million to purchase nearly 1,000 acres of private land – making the largest private inholding within the Palmer Hay Flats State Game Refuge open to the public.

![]() ![]() Not content with its offerings thus far, the Russian development house has returned to the World War II setting with Birds of Steel, a flight game that pleases both camps, even if it leans toward the simulation side. The flight simulation game remains the domain of the PC and its myriad of flight sticks and pedals, though we have seen a few attempts to port this to the console world in the form of IL-2 Sturmovik: Birds of Prey and Apache: Air Assault, both titles courtesy of Gaijin Entertainment. 2, a good deal of them are arcade flight games, where technical details give way to white-knuckle aerial action. From the antiquated stuff of Red Baron to the slightly futuristic fare of Tom Clancy's H.A.W.X. sadly rather too easy to complete".This console generation has seen a good number of flight combat games. Eurogamer said that it was a "rousing aerial shooter. IT Reviews commented that it was "thunderingly atmospheric and visually breathtaking, it has some balancing issues". IGN gave it 8.6 and said that the "strength of its play mechanics and attention to detail make it one of the best choices for console-based flight combat". It achieved a Metacritic average of 80% on the Xbox 360, and 81% on the PlayStation 3. ![]() "Owen Wright": Hurricane Mk.II, Spitfire Mk.IIīirds of Prey received a favourable reception on consoles.Regno d'Italia (Kingdom of Italy) Regia Aeronautica (lit.

The environmental engine also produces high detail, realistic landscapes that allow players to easily see ground support actions. IL-2 Sturmovik: Birds of Prey features hundreds of aircraft taking part in air battles. Players can see real time damage to the aircraft such as holes in the wings and trail lines during dog fights. There are six theatres of war to engage in – The Battle of Britain, Stalingrad, Berlin, Sicily, Korsun and the Battle of the Bulge, representing the main airborne battles of World War II in Europe.īirds of Prey has a new damage effects engine. Players can participate in some of the war’s most famous battles piloting fighters, attack aircraft and heavy bombers across a range of missions. īirds of Prey is based around the large-scale aerial combat and ground military operations of World War II. A demo of the game launched on the PSN and Xbox 360's Xbox Live on 29 July 2009. The game has a campaign mode in which players are able to fly the Allies against the Axis, and also a multiplayer mode in which they are be able to select either faction. As with previous installments of the PC series IL-2 Sturmovik, it depicts combat aircraft from World War II. IL-2 Sturmovik: Birds of Prey, or Wings of Prey on the PC, is a combat flight simulator video game. ![]() ![]() ![]() Erich Treeby, the “Duke of Detail” at custom suit shop Duchess Clothier. ![]() Christine Van Abdouke, owner of athleisure line Perilous Activity.

While the initial focus was to teach students everything they needed to know in order to properly sew, the school has since expanded its scope. Blair, who studied couture sewing in Paris and started three clothing lines of her own, decided to fill this need by founding Portland Sewing in 2002. Image: Courtesy Portland Fashion InstituteĪbout: In the early 2000s, Sharon Blair-a local designer and fashion entrepreneur with more than 20 years of experience-noticed that the only opportunities for individual sewing classes in Portland were degree programs that required lots of time (and money). Here are a few local classes, workshops, and blogs that can help strengthen your fashion foundation. So how can an interested fashionmonger enter the big leagues of Portland apparel? Or where can those who've already been initiated into Portland’s style circle get supplemental skills to give them that extra step ahead? It all feels especially necessary following the big news that the Art Institute of Portland is shuttering, leaving a number of fashion students mid-education adrift. Add to the mix a host of cool fashion shows like Fade to Light and Unmentionable.

He was the longest continuously serving British Foreign Secretary. Grey resigned his post with the fall of Prime Minister Asquith’s government in December 1916. His negotiations abetted the Italian entry into the war on the Allied side in 1915. After the war began, he attempted to limit its scope, and then to find more allies for the Entente. The historian James Joll suggests that Grey’s schoolboy honour might have been what persuaded him to involve Britain in the conflict.ĭuring the crisis in July 1914, after the assassination of Franz Ferdinand, Grey tried to mediate between Austria and Serbia and their allies. However, Britain’s position remained relatively unclear in 1914 - it wasn’t solidly bound to help France in case of war. ![]() His greatest flaw may have been overestimating France’s power while believing at the same time that Germany’s was deteriorating, an idea that led him to tie Britain closer to France and into a possible war. He helped guide the nation through the Moroccan Crisis, two Balkan Wars and the annexation of Bosnia-Herzegovina by Austria-Hungary. His greatest passion was fishing, it seemed he regarded diplomacy more as a burden he had to dutifully bear.ĭespite a lack of enthusiasm, Grey maneuvered Britain’s foreign policy skillfully in the antebellum period. Aloof and cold except to his closest friends, Grey was a Wykehamist who maintained a slightly priggish sense of schoolboy ethics and fair play his whole life.

![]() Video-recording systems have been developed to observe the Daphnia magna movements. EC50 and LC50 are assessed using biomarkers such as the locomotory responses of Daphnia magna. The second is lethal concentration 50 (LC50), which is the concentration of a substance in water that results in the death of at least 50% of the tested population of the aquatic life. The first is the median effective concentration (EC50), which is the concentration of a substance in an environmental medium expected to produce a certain effect in at least 50% of the test organisms (usually planktonic, crustacean, and Daphnia) in a given population under a defined set of conditions. The ecotoxicity of a pollutant can be measured using two indicators. In particular, the locomotory responses of Daphnia magna have been widely used in ecotoxicology because they are sensitive to various toxicants. Biomarkers, such as locomotory responses, living characteristics of Daphnia magna and planktonic, and reproductive effects of Daphnia magna have recently attracted considerable attention 2, 3, 4. Moreover, Daphnia magna is easier to culture in laboratory conditions compared with other organisms. Daphnia magna is a useful bioindicator in toxicology because it is sensitive to toxic substances and has a short life cycle 1. These organisms (or communities of organisms) provide information on the changes in the environment or the quantity of environmental pollutants by changing physiologically, chemically, or behaviorally. Bioindicators are organisms or biological responses that reveal the presence of pollutants by exhibiting typical symptoms or measurable responses. ![]() In the field of ecotoxicity, bioindicators are important in assessing whether aquatic environments are ecotoxic. Finally, we observed Daphnia magna behavioral responses in different concentrations after 0, 12, 18, and 24 h and found that there was a difference in movement according to the concentration at all hours. Both measurements conformed to the guideline provided by the Environmental Protection Agency of the United States therefore, our method can be used for water quality monitoring. The median effective concentration of Potassium dichromate measured in the laboratory and using the device was 1.519 and 1.414, respectively. Toxicity was measured manually in the laboratory and automatically using the high-throughput video tracking system. ![]() We conducted an experiment to observe the impact of toxicants on behavioral responses. Moreover, it was faster than existing tracking systems such as Lolitrack and Ctrax. The proposed tracking system with random forest performed the best in terms of identification (ID) precision, ID recall, ID F1 measure, and ID switches, with scores of 79.64%, 80.63%, 78.73%, and 16, respectively. To measure Daphnia magna movements, we developed a tracking algorithm for automatic background subtraction using k-means clustering, Daphnia classification using machine learning methods (random forest and support vector machine), and tracking each Daphnia magna location using the simple online real-time tracking algorithm. The video tracking system consisted of a constant temperature module, natural pseudo-light, multi-flow cell, and an imaging camera for recording videos. This study aimed to develop a faster and better high-throughput video tracking system using machine learning methods. Specifically, speed is affected in the biomarker detection stage. ![]() However, existing systems are lacking in speed and accuracy. ![]() These high-throughput systems, used for high-speed analysis of multiple organisms, are essential for efficiently testing ecotoxicity. Over the last several years, multiple high-throughput video tracking systems have been developed to measure the locomotory responses of Daphnia magna. Its locomotory responses as a biomarker are highlighted in many studies. Daphnia magna is an important organism in ecotoxicity studies because it is sensitive to toxic substances and easy to culture in laboratory conditions. ![]() |
