嘉定龙凤

first_imgFrom poinsettias to cyclamen and showy amaryllis to Christmas cacti, plants are popular holiday and hostess gifts.Receiving a living plant as a gift is a treat. Caring for them can draw mixed emotions. Fear not. By learning just a little about a plant needs, you can keep your gifts flourishing through the season and sometimes for years after.Here are a few tips from University of Georgia Cooperative Extension to help you care for common gift plants. PoinsettiasPoinsettias come in several colors – including scarlet, ivory, pink and mauve – and have been a favorite holiday plant in the United States for many years. The “flowers” are actually colored leaves, called bracts, which surround the true, tiny yellow flowers in the middle. The colorful bracts may stay bright for months with proper care. Bright, indirect light and frequent watering are essential. Poinsettias need at least six hours of bright light a day to keep blooming for more than a couple of weeks. Temperatures between 65 and 70 degrees are ideal for poinsettias. Keep them out of drafts and away from direct heat sources like fireplaces and heat vents.Water when the soil surface feels dry and just until water drains out of the bottom of the pot. Do not let them stand in water-filled saucers because poinsettias are susceptible to root rot. To keep poinsettias as foliage plants, cut the plant back to about 10-inches when the colored bracts begin to fade in early spring. Feed with a standard houseplant food and repot in a slightly larger container to encourage root growth.By late spring, your poinsettia should have lots of new green bracts and can be moved outside to a sheltered position until frost. It can be maintained as a striking foliage plant for many years, but reblooming requires a strict regimen of dark periods and light.Cyclamen Cyclamen are usually available from October through March. Its graceful, winged flowers of pink, rose, white or crimson rise on long stems above distinctive, heart-shaped leaves that are often handsomely marked.Given cool growing conditions in a well-lighted spot out of direct sun, cyclamen can bloom for several months. Cool temperatures between 50 and 60 degrees are the key to making the flowers last longer. Cooler temperatures can generally be found at an east or north facing window during the winter. The soil should be kept moist, but the pots should not stand in water. Cyclamen are easily damaged from overwatering and under watering. Cyclamen are perennials with thick, tuberous roots, which can last for years. They require rest after blooming. Gradually withhold water until the leaves die back and do not water again for six weeks. New foliage will appear after watering resumes. Bright light and cool temperatures may produce a plant that will reflower. center_img Holiday Cactus There are three types of related species that look like Christmas cacti. They bloom at different times of the year and can be found in flower at Thanksgiving, Christmas and Easter. All require bright sunlight and moderate moisture levels. South windows are excellent locations for holiday cactus. After the six weeks of blooming, remove spent flowers and apply a houseplant fertilizer. Holiday cacti can be grown outside in semi-shade locations. Stem pieces of three segments or more are easily propagated.Amaryllis, Easter lily and chrysanthemum are also popular holiday gift plants. The key to keeping them healthy is mainly common sense. Pay attention to the plant’s care label. All plants need water, but very few do well when left standing in it. Remove any decorative foil from around the pot or punch holes through it to promote good drainage. Most potted plants perform well with a biweekly or monthly feeding of a balanced houseplant fertilizer.last_img read more

first_imgIndonesian energy giant Pertamina has finished drilling 12 new oil wells in the middle of the Sahara desert in Algeria, which marked the state-owned company’s first development project outside of Indonesia.Pertamina’s subsidiary, Pertamina International Exploration Production (PIEP), concluded the latest development of the Menzel Lejmat North (MLN) field in Block 405a, with the wrap-up of the drilling of its 12th well on March 17, according to a PIEP statement released on Saturday.PIEP earmarked US$14 million to drill each well but managed to cut costs and spend between $8.5 million and $10 million per well. The company did not elaborate on how it slashed spending, which resulted in an estimated budget saving of $100 million. The firm also cut short the duration of the drilling, from the targeted 55 days per well to 35 to 45 days per well.“[This] proves PIEP has the capacity and skills to operate overseas,” PIEP president director John Anis said in the statement, adding that field production would peak in 2021.Algeria is among PIEP’s many overseas assets, including in Nigeria, Tanzania and Malaysia, which is expected to boost Pertamina’s upstream business, the largest contributor to the company’s profits.Pertamina’s oil and gas production grew 1.4 percent year-on-year to 919 million barrels of oil equivalent per day (mboepd) in the first quarter, largely contributed by the company’s foreign operation, particularly in Algeria.Pertamina took over the MLN field from United States-based ConocoPhillips between 2012 and 2013 as the latter company underwent an asset disposition program. Block output reached 11,000 barrels of oil equivalent in 2012.The Indonesian company holds a 65 percent interest in the field while Spain’s Repsol holds the remaining 35 percent, despite Pertamina’s efforts to acquire the Madrid-based company’s share.Read also: Pertamina to go ahead with higher oil production plan despite oil price crashTopics :last_img read more

first_imgNote: While the editor is out of town, we are bringing you readings of interest from creation books associated with CEH.The Evolution of Birds: Possible or Impossible?by Dr. James F. Coppedge, Jr (1920-2004)Excerpt from Evolution: Possible or Impossible? by Dr. James F. Coppedge (1973, rev. 1990, ch. 13, “Examples of Phenomena Unexplainable by Evolution,” pp 214-217).A Bird That Found Its Way Home 3,200 Miles in Twelve and One-Half DaysA small ocean-going bird called the Manx shearwater nests in the sand on islands off the coast of Wales. Some shearwaters were banded, put in a crate inside an airplane, and flown to the United States. These birds have not been known to frequent the U.S. east coast.Let’s read the outcome:Manx shearwaters which were removed from their nesting burrows in ‘Vales returned successfully from release points outside their normal range . .. . One of these birds, released at Boston, Massachusetts, returned to its nest 3,200 miles away in 12 days and 12.5 hours!5The account went on to say that the bird probably had to fly at right angles to its normal direction of migration, and that the 250 miles per day average speed suggested it took the shortest possible route!Dr. G. V. T. Matthews of Cambridge Universitycredits birds with . . . ability to estimate the sun’s arc accurately. He claims for them the equivalent of a sextant and a chronometer running on “home time. ” With these they can learn their geographical location anywhere on earth.6Anyone doubting that birds possess these instinctive skills “is left with the difficult task of proposing an alternative, simpler explanation” for the Manx shearwaters’ demonstrated ability we have described, says the Audubon Nature Encyclopaedia.7The wisest of men could never find his way, without charts and mechanical instruments and training, across 3,000 miles of open ocean, starting from a place thousands of miles from anywhere he had ever gone before, and in a short time locate an exact spot on a small specific island.The reader may be aware that an extensive study of this phenomenon has been made by many other scientists. There is even strong evidence that some birds navigate by the moon, a more difficult feat, and some apparently use the north star and stellar constellations in navigating. Bats, on the other hand, can navigate blindfolded.Feathers and EggshellsThere is no way chance mutations could have brought about the development of feathers. Each is a masterpiece of engineering. The center shaft has barbs projecting from each side. Then, smaller barbules protrude from both sides of the barbs. From these barbules, microscopic barbicels project, like tiny hooklets. In some species there are more than a million barbicels in one feather.The hooks of the barbicels fasten neatly onto the neighboring barbules, and this makes a tightly woven vane, as the entire feather is called. If the barbs get pulled apart, the bird can hook them back together merely by preening or running its beak through the feathers! You can do this yourself.Consider the chances of this developing naturally. A feather would be of no help for flying until completed. It would be in the way. When one understands the complex precision of a feather’s design, it is amusing to consider evolutionary claims that feathers evolved from reptile scales!To obtain a bird by chance mutations, one would have to overcome the odds against feathers, computed along with the improbability of occurrence of all the other marvelous abilities birds would need in order to operate successfully at all. The size of the resulting odds would be a figure that would more than fill the cosmos. (George Gamow estimated that a little over 10106 grains of sand would perhaps fill the universe.8 On that basis, we could calculate that the number 10116 would be more than sufficient to fill all cosmic space if printed on thin paper. That is a figure with 116 zeroes.)Hummingbird eggs, by David CoppedgeEvolution cannot explain the origin of the mysterious synchronized process whereby, deep inside a bird’s body, the shell of the forming egg is made from calcium stored shortly beforehand inside the hollow bones.9 The shell is painted with the specific identifying color and with dots, stripes, or shading. Many species can be recognized by these characteristic markings of their eggs.The Amazing Mechanism for Wing-Lift in BirdsNatural selection cannot help one find an explanation for the way a wing is lifted for the upbeat in bird flight. The muscle that operates this lift is not situated on top, but far below the wing. It fastens to the “keel” bone (sternum) -low, center, aft. How does a muscle below the wing serve to lift the wing?There is a tendon that leads upward from the muscle. It passes through a well-lubricated circular canal formed by the joining of three bones, one of which is the wishbone. The way the tendon traverses this opening reminds one of a pulley. At the top, the tendon attaches to the large humerus bone of the wing. The end of this bone is widened and rounded in such a way that the tendon obtains leverage and gives just the right twist to the entire wing for the uplift stroke.With this enchanting engineering arrangement, birds fly, and hummingbirds beat their wings up to fifty times per second. It is interesting to remember this wing-lift mechanism while watching a bird in the air.10 It is fruitless to try to account for the origin of such adroit engineering without an extraordinarily ingenious Planner.References5. Encyclopaedia Britannica ( 1967), s.v. “migration.”6. Audubon Nature Encyclopaedia, “Animal: Navigation,” Vol. 1 (New York: Curtis Publishing Co., 1965), p. 89.7. Ibid. We recall the emotional experience of watching on film as scientists nightly checked the nesting burrow and the excitement as they recovered the weary traveler and verified the band number. The small bird looked quite normal.8. George Gamow, One, Two, Three .. . Infinity (New York: Viking Press, 1961 ), p. 7.9. T. G. Taylor, “How an Eggshell Is Made,” Scientific American (March 1970), pp. 89-94.10. The author has traced this tendon in several species, including the crow, Stellar’s jay, and the turkey. It is standard equipment for most present-day birds. In the turkey, two tendons pass through this opening, apparently being needed because of the greater weight and width of the wing, and consequent widening of the end of the bone, providing the essential control of wing attitude. There is no reasonable explanation of any evolutionary development cf this and other flight equipment. Speaking of flight, William W. Ballard, Professor of Biology at Dartmouth College, wrote, “And the birds, having by quite unknown steps developed the ability to escape attack through the air, managed a parallel adaptation to many terrestrial niches.” (Ballard, Comparative Anatomy and Embryology,[New York: The Ronald Press Co. , 1 964], p. 41 .)(Visited 575 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

first_imgStep 1. Use HSL SecondaryAs Justin Odisho points out, it’s best if your talent is wearing something with a different color than the background so you’ll avoid changing their clothing too drastically (especially if you want any continuity in your film). So, create an adjustment layer, and put the clip on top of your original. Then open up the Lumetri color Panel, and then open HSL Secondary.Step 2. Capture the Right ColorTo distinguish the color you’d like to change in the scene, grab the Ink Dropper tool and drag it over to the image and pick a point (in this case, it’s a bright green tree). Since the trees are changing in color due to the different light, grab the Plus Ink Dropper and drag it over the area of leaves to capture the range of brightness in the green leaves. You can pull the sliders in or out to refine your adjustment and see exactly what color you’ve selected.Step 3. Open the Color WheelNow we’re going to change the colors, so open up the color wheel. If you want to use the tri color adjustment with Shadows, Midtones, and Highlights, you can, but Justin Plays with the one Color Wheel for this example. He recommends just playing around with the colors so you can easily decide what shade works best for your shot. Also, try not to go too saturated with your colors due to how fake the final product might look.Odisho recommends, since you’re already working with the Adjustment Layer, to just go ahead perform the basic color grading you need to while you’re already in Lumetri (thus saving you time down the road).Want to learn more about how color grading can save your shot?

Often, you’re rushing toward a deadline with no days or hours to spare. You have to take what you can get when you can get it.However this doesn’t necessarily mean you have to settle for a shot you don’t want. Here are a few ways to alter the time or place of your shot during post-production. In this particular example, we’ll learn how to change your shot from summer to fall — all in Premiere Pro.
