![]() In 1838, a Scotsman named Robert Davidson built an electric locomotive that attained a speed of four miles per hour (6 km/h). American blacksmith and inventor Thomas Davenport built a toy electric locomotive, powered by a primitive electric motor, in 1835. In 1835, professor Sibrandus Stratingh of the University of Groningen, in the Netherlands, built a small-scale electric car, and sometime between 18, Robert Anderson of Scotland invented the first crude electric carriage, powered by non-rechargeable primary cells. Main article: History of the electric vehicleĮlectric motive power started in 1827 when Hungarian priest Ányos Jedlik built the first crude but viable electric motor, which used a stator, rotor, and commutator the next year he used it to power a small car. There are more 2 and 3 wheel EVs than any other type. Much of this growth is expected in markets like North America, Europe, and China a 2020 literature review suggested that growth in the use of electric 4-wheeled vehicles appears economically unlikely in developing economies, but that electric 2-wheeler growth is likely. As of July 2022 the global EV market size was $280 billion and was expected to grow to $1 trillion by 2026. Electric vehicle sales may increase from 1% of the global share in 2016 to more than 35% by 2030. A total of 14% of all new cars sold were electric in 2022, up from 9% in 2021 and less than 5% in 2020. The International Energy Agency has stated that governments should do more to meet climate goals, including policies for heavy electric vehicles. During the COVID-19 pandemic, lockdowns reduced the number of greenhouse gases in gasoline or diesel vehicles. Increasing public interest and awareness and structural incentives, such as those being built into the green recovery from the COVID-19 pandemic, are expected to greatly increase the electric vehicle market. Government incentives to increase adoption were first introduced in the late 2000s, including in the United States and the European Union, leading to a growing market for vehicles in the 2010s. Internal combustion engines were the dominant propulsion method for cars and trucks for about 100 years, but electric power remained commonplace in other vehicle types, such as trains and smaller vehicles of all types. ĮVs first came into existence in the late 19th century, when electricity was among the preferred methods for motor vehicle propulsion, providing a level of comfort and ease of operation that could not be achieved by the gasoline cars of the time. For road vehicles, together with other emerging automotive technologies such as autonomous driving, connected vehicles, and shared mobility, EVs form a future mobility vision called Connected, Autonomous, Shared, and Electric (CASE) Mobility. EVs include, but are not limited to, road and rail vehicles, surface and underwater vessels, electric aircraft, and electric spacecraft. It can be powered by a collector system, with electricity from extravehicular sources, or it can be powered autonomously by a battery (sometimes charged by solar panels, or by converting fuel to electricity using fuel cells or a generator).

![]() ![]() Probably the best way for home gardeners to avoid the annoying problem of powdery mildew is to select and plant mildew resistant varieties. If cultural practices fail, fungicides can also be used to control powdery mildew. Remove and destroy disease-infested plant debris in fall. Divide bee balms every 2 to 3 years to prevent overcrowding. Move plants growing in partial shade to a sunny location. When planting bee balms, select a site that receives at least 6 hours of direct sun each day and space plants 2 to 2½ feet apart. ![]() ![]() Symptoms are most severe on overcrowded plants and those growing in partial shade.Ĭultural practices can reduce the severity of powdery mildew. In the garden, limit mold growth with judicious watering, pruning, and thinning of. Powdery mildew is a common fungal disease on bee balms. Garden fungicide sprays such as Defender work to prevent the spread of Powdery Mildew.The symptoms on your bee balms ( Monarda spp.) are most likely due to powdery mildew. When an outbreak does occur, pick off the infected leaves and throw them in the garbage instead of the composter. Powdery Mildew spreads by spores so water drops that splash onto infected leaves cause spores to spray onto healthy foliage, making the problem worse. Try using soaker hoses instead of sprinklers. When watering, keep the stream low to the ground focusing on the soil, not the leaves. Since the plant looks pretty well spent/bloomed out, cut it back and dispose of the cuttings anywhere but in your compost pile - if. You could spray the plants with a fungicide like horticultural oil or Armicarb (a baking soda formulation) to see. That being said, it is hard to know without looking at a sample. Shrubs such as roses and lilacs can be pruned in order to maintain an open growth habit. The only fungal disease they really have a problem with is powdery mildew and usually that is just a powdery coating on the foliage and this looks a little different. Be sure to encourage good air circulation between plants by thinning and dividing every couple of years. Bee balm thrives in USDA plant hardiness zones 4 through 9. Plant it in large clumps so that the pollinators have plenty to feed on in one concentrated area. It’s a wonderful companion plant for the garden since it attracts pollinators. The best control for powdery mildew is to prevent it from occurring in the first place. It’s used to successfully prevent fermentation and mold growth in bee colonies. Many plant breeders have been working feverishly to breed new strains of these plants that are resistant to powdery mildew so keep this in mind before purchasing new plants. Some species of plants are more susceptible to powdery mildew than others, such as phlox, lilacs, bee balm, veronica, lungwort, roses and asters, to name a few. Moisture and high humidity (or poor air circulation) are the most favorable conditions for powdery mildew to grow in. We tend to see powdery mildew outbreaks more during years that are humid or damp. A nice layer of top-dressed compost in the spring followed by a couple inches of mulch will offer. There are two common fertilization techniques for bee balm. This is caused by a fungus called powdery mildew. Plant bee balm in soil with a pH range between 6.0 and 6.7 for best growth, and I like to add some compost to the bed to give the soil extra nutrient value before planting. ![]() In summer, it’s common to see beloved plants turn from beautiful green foliage to a spotty gray mess. ![]() ![]() ![]() The paid version does not record unlimited video lengths you only get an hour of recording time.You need this, because you can’t really rely on screen recording Chrome extensions.

Using Python dictionaries is simple to learn, but mastering them and remembering the syntax when you need it requires some practice, so we have several exercises at the end of this tutorial lesson. Among the collection data types - the types programmers use to store and retrieve other objects - dictionaries are probably the most widely used class next to Python lists. In case when by " 'AND' search" and using iter you meant to search both posts then again collections.Python dictionaries are a popular and easy-to-use built-in type. duplicates = dict(p1.items() & p2.items()) ![]() However this is only useful if you're looking for duplicates in terms. If you want to intersect items of both posts, which means to match IDs and documents, use code below ( credits to DCPY). Or if you don't want to create separate intersection dictionary: from collections import ChainMap To iterate documents for common_ids, collections.ChainMap will be most useful: from collections import ChainMap However if you want to iterate documents you have to consider which post has a priority, I assume it's p1. If you want to intersect IDs from posts ( credits to James) do: common_ids = p1.keys() & p2.keys() Your question isn't precise enough to give single answer. If you are trying to get these gains looking at a different language or Cython might be better.

In Freehand doing these kind of tasks was so much easier and totally precise when you did that. When you grab a rectangle and want to place it in the corner of a guide intersection, you need to grab the exact corner to do that and drop it very close to the intersection and it does snap to the guides, BUT when you grab the rectangle from the middle (when you don't have the "Object Selection by Path Only" activated) it's impossible to snap it to any guide!!! That is a bum! So I need to activate the bounding box, zoom in resize on one corner then go to the other and do the same, it's ridiculous. I have 2 guides one vertical and one horizontal that cross eacother, I want to start a rectangle (Tool M) from the intersection to another intersection of another 2 guides, when you place the cursor near the starting intersection it doesn't snap to the guides, neither on the other intersection where you want the rectangle to end!
