Identifying American Basswood Trees

Identifying American Basswood Trees Tilia is a genus within the Linden family (Tiliacea). This family contains about 30 species of trees that are native throughout most of temperate Northern Hemisphere.  The greatest species diversity of the lindens is found in Asia. It exists only scattered in pockets throughout  Europe and eastern North America. The trees are sometimes  called lime in Britain and linden in parts of Europe and North America. The most common name for the tree in North America is American basswood (Tilia americana),  but there are several varieties with separate names. White basswood (var. heterophylla) is found from Missouri to Alabama. Carolina basswood (var. caroliniana)  is found from Oklahoma to North Carolina and south to Florida. The fast-growing American  basswood  is among the largest trees of eastern and central North America. The tree will often support several trunks off its base, will prolifically sprout from stumps, and is a great seeder. It is an important timber tree in the Great Lakes states. Tilia americana is the northernmost basswood species. Basswood flowers produce an abundance of nectar  from which choice honey is made. In fact, in some parts of its range basswood is known as the bee-tree, and can even be identified by the honey bee traffic.   Basswood Tree Identification Basswoods asymmetrical and lopsided heart-shaped leaf is the largest of all broadleaf trees, nearly as wide as it is long at between 5 and 8 inches. The rich green upper side of the leaf is in contrast to the underleafs paler green to almost-white color. The basswoods  small greenish flowers are uniquely attached and hanging under a pale, leaflike bract. The resulting seeds are in a hard, dry, hairy, nutlike fruit, which is quite visible during the fruiting season. Also, take a close look at the twigs and you will see them zigzag between oval buds with one or two bud scales. This tree should not be confused with the non-native urban basswood called little leaf  linden or Tilia cordata. The leaf of the linden is much smaller than basswood and typically, it is a much smaller tree. Characteristics Leaves: Alternate, broadly ovate, coarsely saw-toothed, notched at the base.Bark: Dark gray and smooth.Fruit: Elliptical nut-like, hard seed.

5 Basic Principles Of Energy Security

5 Basic Principles Of Energy Security Energy security is put in first place among the priorities facing the European Union. Although the problems of ensuring energy security were standing in front of a united Europe from the beginning of the integration process in recent years they have acquired the greatest relevance and importance for the EU. This is due to the fact that today the EU depends 50% on external energy supplies to its market and on the policies pursued by supplier states. In addition, European countries are concerned about the well-known problems with the energy supply for them against the backdrop of turmoil between Russia, as the main EU energy supplier and Belarus and Ukraine, through whose territory the Russian hydrocarbons are delivered to the West. Russian-Ukrainian standoff on the issue of gas prices and transportation is the major concern of EU member states and compel them to talk about the need to diversify energy supplies. Concentrating 7% of world population, more than a quarter of world GDP an d 20% of world trade, the EU has only 2% of the world’s â€Å"black gold† and 4% natural gas. Limitation of its own resource base in Europe accounts for a significant dependence of the EU on external energy supplies. The European natural gas market is the third largest in the world. The volume of gas consumption in EU countries reached 513 billion m3 (21% of world consumption). Russia is the second largest EU oil supplier and provides 33% of the EU â€Å"black gold† needs. The Russian Gazprom is the leader in EU natural gas supplies with 46% of total. If we talk about security of energy supplies, the main task in this area is the energy sectors geographical and resource diversification i.e. the expansion of supply sources, supply routes and pipelines. The EU security in energy sector NABUKO I EU The European Union is seeking to protect self from energy dependence on Russia with diversification of natural gas supplies policy by agreements with non-conventional en ergy suppliers, the Caspian states (Caspian states have only 4-5% of world’s gas reserves). But due to the unreliability of Russian energy supplies through third countries (Belarus and Ukraine) as well as the possibility of using Russian resources as a political tool, transporting Caspian Sea hydrocarbons (Azerbaijan, Kazakhstan and Turkmenistan) to the West has acquired great importance to the EU. Improve supply reliability and energy security EU responsible implementation of the Southern Gas Corridor. The planned corridor is composed of three parts: the Trans-Caspian gas pipeline (the project provides for delivery of natural gas from Kazakhstan and Turkmenistan to Azerbaijan), Baku – Tbilisi – Erzurum (from Azerbaijan through Georgia to Turkey) and Nabucco (from Turkish territory, via Bulgaria, Romania, Hungary Austria). Thus, the reliability of energy supply in Europe is due to the changing geography of supply, increasing the number of exporting countries, th e creation of new infrastructure facilities. In the face of increasing competition from non-traditional suppliers of hydrocarbons Russia is very important to maintain the competitiveness of their energy in the European market, to ensure effective and reliable conditions for their transit to Western Europe.

Is Sex Education Beneficial or Harmful to Teenagers Essay

Is Sex Education Beneficial or Harmful to Teenagers - Essay Example In addition to all this, there is an impulsive drive within the teenagers to engage in forbidden adequate notwithstanding the absence of wisdom and guidance. As a result more harm than good can be done. Opponents of sex education argue against sex education by claiming that this type of education opens kids to ideas that they had not thought about before.

By education about sex, ma ny opponents feel that schools try to step into the shoes of the family. Sex education can be very healthy for teens. It offers them guidance and prevents teenage pregnancies.

Un-American Essay Example | Topics and Well Written Essays - 500 words

Un-American - Essay Example The altered political ideology following the communist expansionism of the ‘Cold War’ had domestic repercussions in American society. The stage was set by F.D. Roosevelt, who conceded control over post-war Eastern Europe to the Soviet Union, granting â€Å"moral legitimization to what Stalin had acquired by sheer force† (Nisbet, qtd. in Maltsev and Simpson, 15). The subsequent race for nuclear supremacy, and the policy of ‘Mutually Assured Destruction,’ â€Å"inspired widespread fear of impending nuclear war† in Americans, who built bomb shelters in their backyards (Foner, 891). This let the â€Å"sweeping tide of anti-communism† (Pike, Global Security organization web site) engulf America. Any criticism of American society was construed to be ‘Un-American.’ Senator McCarthy’s witch-hunts made ‘McCarthyism,’ with its connotation of ‘unsubstantiated accusations of disloyalty’, a dominant theme of the 1950’s. America of the 1950’s witnessed â€Å"the twentieth century’s greatest citizens’ movement – the black struggle for equality† (Foner, 899). The rigid racial boundaries of the previous decade persisted in post-war America. The new suburban landscape was racially segregated, and reinforced by methods, such as ‘block-busting’ (Foner, 863). Jim Crow laws flourished in the South. The American judiciary led the assault on racial discrimination. In 1944, the US Supreme Court ruled racial segregation unconstitutional in public schools. Rosa Parks’ defiance led to the Montgomery Bus Boycott in 1955 and Martin Luther King burst upon the scene with his charismatic leadership. Despite strong resistance, America’s march towards a truly equal, ethnically integrated society began in earnest. Economically and culturally, the 1950’s gave a new definition to ‘the American way of life.’ Most significantly, â€Å"consumerism replaced economic freedom and democratic participation as central definitions

Marketing changes :: essays research papers

There have been many significant changes within our society. One of this is the changing gender roles within our society and another is the changing attitudes toward health & fitness. Both of these have impacted on consumer preferences or buying habits. Gender roles are no longer as accurate as it once was. There is now a trend of reserved roles. This is due to the continued growth in a number of dual income households. There has been an increase of women in the workforce in the fast few years. Women in the paid workforce spend less time shopping than the stay at home women. They tend to shop in the evenings and on weekends due to their busy schedules. They tend to swap stores which they shop in due to convenience. This happens due to the time constraints but still earning an income they are less likely to be price conscious. The working women are more likely to purchase convenience foods and products and they tend to be brand and store loyal. In this current society women have different material (clothing) needs to the stay at home women versus the working women. Males are now also more involved in purchasing household products. Some men now do their shopping via the internet rather than physically enter the stores. Because they use this type of method it is harder to record their purchasing habits. They have moved away from traditional roles. Women are now taking a greater role in deciding which products to buy. Buying decisions have moved away from being male/husband denominated to become automatic. i.e. many families now have two cars and they tend to make their purchase decision separate. Direct marketers are now targeting time pressured women who use catalogues, telesales and internet sites as ways of shopping may it be for clothing as well as household and family needs. They have also used this method to target men who now also do the shopping. Marketers who are aware of this change have developed changes to their product design and advertising appeal/styles. Some advertisements have been positive and some offending. I.e. Detergent Ads. Marketers are increasingly attempting to cash in on the belief that men are getting in touch with their feminine side. Many businesses have now marketed their services/ products to suit these changing gender roles. One of this is restaurants. Plenty of them now offer home delivery service. There is also an increase in takeaway stores catering for these busy men and women.

Blue White Selection

Blue white selection  is a widely used method in screening recombinants in cloning. This is based on the gene product of lac z gene. The plasmid vectors contain this gene which produces  ? galactosidase  enzyme. When a gene is inserted close to  lac z gene, the reading frame will be distorted and the gene is inactivated. So the transformed cells will not produce this enzyme and are called competent cells. After the recombination, the bacterial cells are grown in a medium containing X gal (5-bromo-4-chloro-indolyl-? D-galactopyranoside) and  IPTG (Isopropyl ? -D-1-thiogalactopyranoside). IPTG acts as the inducer for lac z gene and enhance the production of ? galactosidase. When it is produced, combines with X gal to form a blue colour complex called  5,5†²-dibromo-4,4†²-dichloro-indigo  which is insoluble. The transformed colonies will appear white in colour and non- transformed cells will appear blue in colour. This method is also called as insertional inactiv ation of lac z gene. Hybridization  techniques are widely used to identify recombinants.This is based on the ability of nucleic acids hybridize with complementary DNA. The transformed cells are transferred on to a  nitrocellulose membrane  which is subjected to cell lysis. The double stranded DNA is converted to single stranded DNA and immobilized on the membrane. Then it is treated with radiolabelled  probes  complementary to target DNA. If the desired DNA is present, the probes will be hybridized which can be detected by autoradiography. Apart from these methods,  immunochemical methods  are used to detect protein products to screen recombinants.

America Needs More Government Programs to Pull Children...

The face of poverty is changing in the United States. When someone mentions that a person is living in poverty, we are inclined to think of a bum living on the street, eating at shelters, and using whatever money they have for alcohol, drugs and tobacco. Usually we visualize this person as being a middle-aged male with drab clothing and a long beard. This description may have fit the average person living in poverty or on the street a few years ago, but it is no longer a correct generalization. Children are the face of poverty in 2015. These children have little chance to rise up out of the lifestyle they are born into. Many of these children are born to teenage girls. The economic states of these mothers and their lifestyles many times†¦show more content†¦Some people are born into stable families, so they have m ore opportunities than those that are born into poverty. No matter how people feel toward the choices that the parents made, we cant hold this against the child. One other thing society canà ­t do is simply hand out money or food stamps to the families of these children. Who knows where this money is going or what it is being used for? The food stamps could be intended to feed a baby, but instead they could be used to buy food or items that a child will never see. It is also all to common for parents living in poverty or on the streets to use what money they get for alcohol or cigarettes. Instead of handing out money to these people, they should be put i n treatment programs that could help them fight their addictions. This would be of great benefit to their children now and in the future. Not all mothers and fathers in need of assistance are going to be irresponsible with what they are given, but we ca n not take the chance of having the money wasted and the children neglected. Who wants the money that they worked for going to someone else, so that person does not have to work, yet still gets paid regularly just because they had a baby when they were n ot ready? As I stated before, not all parents living in poverty are irresponsible and many have legitimate reasons for being where they are.
