Plants begin their lives in the form of seeds. The embryo inside the seed is considered as the next sexual generation of plants. Seed germination is an important phase in plant’s life. We will write a custom essay sample on Plants or any similar topic only for you Order Now Successful seed germination is vital in every reproducing species in order to perpetuate itself. By definition seed germination is when the dry seeds shed from its parent plant, takes up water and is completed when the embryonic root visibly emerges through the outer structure of the seed (seed coat) (Hasanuzzaman et., al. 2013). Bewley (1997) described that it includes different events that commence with the uptake of water by the quiescent dry seed and terminate with the elongation of the embryonic axis. The visible sign that germination is complete is usually the penetration of the structures surrounding the embryo by the radicle (radicle protrusion). Several authors had reported the importance of germination in the life cycle of plant. According to Hubbard et., al (2012) this stage in the life cycle of the plant is considered as a critical event as germination is the first step in determining the survival rate of the crop thereby affecting its productivity. Meanwhile Donohue et., al. (2010) reported that seed germination is an important developmental phase change in the plant life cycle, which plays critical roles in seedlings establishment and consequently in environmental adaptation. The process of seed germination involves several complex processes and activation of the seeds metabolic pathways which eventually leads to the emergence of newly grown generation of plants. Many of the specific biochemical and physiological processes which characterize germinating seeds, particularly those occurring in storage organs, are special during this stage (Bewley and Black 1994). Knowledge of the germination process and of the seedling establishment and development, involving morphological, physiological, biochemical as well as molecular mechanisms and features is of essential importance for taxonomic, ecological and agronomic studies of certain plants. There are several different gene expression that underlies plant development, the relative specificity of these processes suggests that distinct gene sets are activated and repressed during this stage. The reaction between activation of essential enzymes, sequential release of hormones and the energy relations of the process during seed germination are very significant in understanding the appropriate establishment of plant for its adaptation. Identifying these genes and defining mechanisms involved in regulating their expression will aid in understanding the control of germination-specific mechanisms. This review will provide an overview on the mechanism of gene expression in mainly in angiosperm plant. The different genes expressed in embryos and seedlings will also be tackled A brief description of on the hormonal changes and hormonal balance that triggers or promotes gene expression during germination is also discussed in this paper.

It was a warm summer day when his life turned upside down Essay Example For Students

It was a warm summer day when his life turned upside down Essay It was a warm summer day when his life turned upside down. He and some friends had been enjoying some delicious pizza you could only find at privately owned Italian restaurants. They took advantage of the luxurious warmth and sat on the front patio where they could watch people pass by on the busy Bloor Street. But soon the sunshine was cast aside, and as with most hot humid days the bright blue sky was overtaken with black masses. They were just finishing the last slice when a crash from the sky seemed to let loose an ocean of water. You look like drowned rats! exclaimed the owner with much amusement as they tore inside. Thats some fucked up weather, laughed one friend while examining his now see-through shirt. But he was no longer paying attention. His eyes had been diverted to a young woman who had just walked in. Her long brown hair, dripping wet and tousled, gave her a wild, untamed look. Her almond-shaped green eyes were captivating, and could lure anyone in who dared stare at them too long. Her heart shaped face didnt have a single blemish. His heart fluttered at a rate that must be unhealthy, and his breath was taken away by the amazing creature that stood before him. Yet at the same time his heart dropped and he felt sadness and regret wash over him as he realised the hushed words and party gossip had been true. Her eyes had lost their sharpness and were dull and blood-shot. Her hair had been slightly askew as she had ran in, a tell tale sign that her hair was not real. Her cheeks no longer had their adorable roundness and she looked as if she had lost at least 30 pounds. She walked with a slight limp. He never knew someone could change so much in two years. He never knew that after not seeing someone for so long that feelings long buried and forgotten could come back to you with such an over-whelming force his knees felt weak. She smiled a crisp smile of recognition, which revealed small creases in her young face. Creases that told the truth of a year of suffering, though the lips might tell other lies. Hey, how have you been? he asked, praying she would tell the truth and not just answer with a simple fine. Fine. Thats really great to hear, what have you been up to? A lot of stuff. She averted his eyes when she talked to him, talking past him, as if the wall behind him was a more interesting conversationalist. Thats cool. And you? Not really anything to tell you the truth. Im still in school, still working at Ponderosa. She smiled at the wall. Thats nice. He didnt want to continue this agonizingly meaningless small talk. He wanted to hold her and tell her it would be all right, that she could beat this disease that had consumed her body  until there was hardly anything left. He wanted to say call me when it hurts too much, call me when you feel like giving up, just call me and it will be all right. But that sort of talk wasnt allowed during a chance-meeting encounter with an ex two years after youd last spoken. All that was allowed was small talk. Horrible, un-fulfilling small talk. Are you okay Jetta? he blurted out. She giggled nervously. Yeah, just a bit wet, why? Some friends have been telling me that you havent been okay. .ucb7ea371b80109027d3c88a55f44bf46 , .ucb7ea371b80109027d3c88a55f44bf46 .postImageUrl , .ucb7ea371b80109027d3c88a55f44bf46 .centered-text-area { min-height: 80px; position: relative; } .ucb7ea371b80109027d3c88a55f44bf46 , .ucb7ea371b80109027d3c88a55f44bf46:hover , .ucb7ea371b80109027d3c88a55f44bf46:visited , .ucb7ea371b80109027d3c88a55f44bf46:active { border:0!important; } .ucb7ea371b80109027d3c88a55f44bf46 .clearfix:after { content: ""; display: table; clear: both; } .ucb7ea371b80109027d3c88a55f44bf46 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .ucb7ea371b80109027d3c88a55f44bf46:active , .ucb7ea371b80109027d3c88a55f44bf46:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .ucb7ea371b80109027d3c88a55f44bf46 .centered-text-area { width: 100%; position: relative ; } .ucb7ea371b80109027d3c88a55f44bf46 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .ucb7ea371b80109027d3c88a55f44bf46 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .ucb7ea371b80109027d3c88a55f44bf46 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .ucb7ea371b80109027d3c88a55f44bf46:hover .ctaButton { background-color: #34495E!important; } .ucb7ea371b80109027d3c88a55f44bf46 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .ucb7ea371b80109027d3c88a55f44bf46 .ucb7ea371b80109027d3c88a55f44bf46-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .ucb7ea371b80109027d3c88a55f44bf46:after { content: ""; display: block; clear: both; } READ: American Airlines Swot Analysis EssayAnd what friends would this be? her arms crossed her chest and she took a step back, but she allowed her gaze to meet his eyes.

Advancements In Computers In The Last Ten Years Essays -

Advancements In Computers In The Last Ten Years Advancements in Computers in the Last Ten Years English 11 Hour 6 Mrs.Winn March 21, 2001 Lipske 2 Computers date back all the way to 300B.C. with the invention of the abacus. This was a calculating devise to do math and it made the people of that time lives a lot easier. That is what the computers of today do but so much more. I will start at the basics of computers while trying not to boar you. The first real computer that actually made calculations was the ENIAC that was made by the government in 1943. It costed $500,000, weighed over 30 tons, had 19,000 vacuum tubes, and consumed almost 200 kilowatts of electricity (computer chronicles 8). Now we have advanced to laptops that are one inch thick and 15 inches wide and can do a lot more than the ENIAC could. There have been thousands of advancements and new technology in computers in the last ten years but I am only going to skim the tip of the iceberg. In 1990, there were tons of new computers and new software but the big issues were the new processors that were super fast for their time. They could go at speeds up to 33mhz, which is how fast your computer brings things up on the screen. In 1991 Microsoft come out with a version 5.0 MS-DOS mode which gave computers more space to run their programs. Lipske 3 Also in 1991, Intel introduced a 50mhz microprocessor, which kill its other 33mhz processor of last year. Then a few months later MIPS Technologies come out with a 100mhz processor which started to make the processor group of the computer a very competitive area to come up with new technology for. In addition Hewlett-Packard Co. made the very first color scanner that could scan whatever you wanted and put it into your hard drive. 1991 was a big year for new technology in computers but thats not all. Pixar began to work with Walt Disney Company to make a film that was completely computer animated and eventually come up with the movie toy story. In 1992 there were three major changes in computers and the technology. First Microsoft stock reached a record high for a computer stock ever and peaked at $113 a share that year. Next Microsoft shipped its 3.1 version of window and it is a big hit and was the most abundant program on the earth. Next there was a big separation of powers that was IBM, Microsoft signed a divorce, and IBM became its own company. Lipske 4 1992 the divorce between Microsoft and IBM was the big factor of the year and you will see why in 1993. In early January of 1993, IBM reports a huge loss of $4.96 billion, which almost put the company down and out but not yet. Then in March of that year Intel came out with their fastest processor which was called the Pentium processor which ran at 200mhz. In 1993 you could see what a huge loss IBM took after getting away from the powerhouse called Microsoft. 1994 was a very slow year for all companies and technology for them. The only major thing that happened was Novell bought the Word Perfect Corporation for U.S. at $850 million. Also that the faster processor race was still on. 1995 was another big year especially for Microsoft. Microsoft releases Windows 95, which is the Windows that I am typing this on and in 95 was a break threw because of its graphics and easy use. Next Sony electronics releases PlayStation, which was built with a small computer in it for video games. Lipske 5 In addition, Apple computers released the first laser printer which was faster than the DeskJet printers and a was a better quality of clearness printed. 1995 became a really big year for the faster processor! 1996 was another slow year but the race for the faster processor was still on. However, there was one big push ahead with Microsoft making the Internet Explorer 3.0. Which mad the Internet at your own house organized and made a search engine. 1997 Microsoft bought WebTV for $425 million which made the Internet easy to use

Why plagiarism doesnt pay - Emphasis

Why plagiarism doesnt pay Why plagiarism doesnt pay Here are the plagiarists of Internet Town With Ctrl+C and clattering keys They prowl and creep when you’re asleep   And take whatever they please. Sounds good, right? They aren’t my words though: we lifted them from Allan Ahlberg’s Cops and Robbers, then made a couple of tweaks. These days, pinching stuff from the internet is all the rage, simply because it’s (a) incredibly easy and (b) a short-cut to mountains of free web content. Obviously, plagiarism is unethical. We all know that text or images taken from another source should be properly attributed, in a footnote or through ‘quote marks’. But ethics aside, plagiarism is simply bad business. Ello ello, whats going on here? Let’s say that you copy and paste a chunk of text from a website into your own report, press release or company brochure. It may look good. It may read well. But the basic fact is, people will notice. Stolen goods – in writing just as at a car-boot sale – stand out. If they find your content via a search engine, they’ll immediately see that yours is not the only site to carry the text in question. If they’re editors and run plagiarism software (such as Turnitin or iThenticate), they’ll quickly see through your sleight-of-mouse. Most importantly, copied text stands out to anyone who pays enough attention to your writing (and if people aren’t paying enough attention to your writing, you’ve got a whole other problem). Changes in tone, style, vocabulary and voice register with readers, even if they don’t realise it. It makes for a bumpy ride. It makes the reader less comfortable with your content. And it makes them less likely either to sympathise with you or believe you (or ‘you’). OK, so you think again, and go to what we might call ‘level 2’ plagiarism. You rip off, but you re-write. You change maybe one word in ten, alter ‘cannot’ to ‘can’t’, cut out a handful of adverbs. Presto! ‘New’ content. There are two problems here. Which of the two you encounter depends on how good a writer you are. Problem one: the hybrid In the first case, you wade in, thesaurus in hand, and make a terrible hash of the job. You lack the technical knowledge to amend the text appropriately (which is probably why you stole it in the first place). A synonym in the wrong hands can be a dangerous thing – and the results are likely to both point up your obvious attempt to plagiarise and cause the reader great amusement/frustration. I’ve encountered these weird hybrids in the wild many times. Let’s create one at random. Here’s the original text: The potential loss on a short sale is theoretically unlimited in the event of an unlimited rise in the price of the instrument; however, in practice, the short seller will be required to post margin or collateral to cover losses, and any inability to do so on a timely basis would cause its broker or counterparty to liquidate the position. That’s from Wikipedia’s page on ‘short-selling’, a financial concept chosen at random from the almost infinite number of topics about which I know nothing. We want to use this content in our report, but we don’t want anyone to know that we purloined it. Right – where’s that thesaurus? The would-be slaughter on a dumpy auction is tentatively on tap in the event of an infinite augment in the consequences of the utensil Hmm. Perhaps this isn’t the best approach after all. This example may seem far-fetched (it was done using MS Word’s ‘thesaurus’ tool, by the way), but I have come across real-life examples that are just as bizarre. It’s what comes of failing to show sufficient respect for the process of writing – of imagining that one word is just as good as another, that writing skills can be bluffed and technical know-how mimicked without consequence. The consequence is, of course, that the shortcomings you hoped to conceal by appropriating another’s work are laid bare. In the end, it undermines your reputation, rather than enhancing it. In this case, shortcuts just won’t cut it. Expertise is what you need, and if you don’t have it yourself, you’re better off buying it in than trying to rip it off. Problem two: the long shortcut And this is where the second problem comes in. Perhaps you do have the knowledge to make the necessary amendments without turning the content into a laughing stock. Perhaps you know that ‘short-selling’ might be better replaced with ‘going short’ or ‘shorting’ than with ‘dumpy auction’. Clever you! But then in that case, why are you copying content in the first place? More often than not you’ll find that, by the time you’ve re-worked a sentence to eliminate every trace of the original, you’ve used just as much time and effort as if you’d bitten the bullet and written it yourself. It reminds me of the story of the boy who tried to cheat in his exams by writing the answers on his shirt cuff. By the time he’d done that, he’d memorised them all anyway. This is a confidence issue. You have to remember that, very often, if you’re good enough to fake it, you’re good enough to do it for real. Ultimately, even if you’re prepared to ruthlessly jettison what they taught you at school about stealing being wrong, it’s still seldom a good idea. If you do it badly, you’ll get caught – and if you do it well enough not to get caught, it probably wasn’t worth doing it in the first place.

Commercial Property Law Essay Example | Topics and Well Written Essays - 2250 words

Commercial Property Law - Essay Example Any conflict between the parties shall be resolved in consonance with the tenor of the contract, the spirit and letter of the relevant laws as well as applying common law principles and judicial interpretation rendered by courts or tribunals on similar issues. The interpretation of the parties’ rights and obligation in contractual relationships vary and oftentimes the interest of one party may cloud its judgment thus it is important that independent minds should offer impartial opinions to aid the parties in making informed decisions. It is in this context that our firm was commissioned by Tomes Limited (Tomes) to evaluate its standing in a leasehold agreement whether its posturing against the landlord is valid. The account was assigned to me for appropriate action. II. Factual Background The leasehold contract over an Old Victorian Townhouse was constituted on 1 April 1997 for a period of twenty five years where rent review shall be made at the end of the 5th, 10th and 15th y ears of the term provided that such intention is communicated to the tenant within the 5th, 10th and 15th years. The break clause option is available to either party provided that notice shall be given to the other party during the first six months of the 15th year. The leasehold states that the â€Å"tenant shall put and keep the premises in tenantable repair to include the decorations, wall-surfaces, window frames, glazing, and casements.† The Landlord and Tenant Act 1954 shall be applicable as no effort to exclude its operation was undertaken by the parties. Tomes assumed the lease three years ago and utilizes the demised premises as a book shop—an activity which is not prohibited by the user clause. Its peaceful occupation of the demised properly was interrupted when the landlord demanded that Tomes undertake repair on the cracks in the corners of and right across all the ceilings after a structural inspection revealed that cracking has been caused by flexion of fl oor joists induced by the load imposed by book shelves. The engineer who conducted the structural investigation concluded that the joists may not have been permanently damaged by the load but nonetheless recommends the installation of steel reinforcement of the joists in the floor voids along with load reduction as the upper floors are not particularly well suited to the demands of book storage. III. The Opposing Views The controversy escalated when the landlord insisted that the reinforcement works as recommended by the engineer should be executed by Tomes pursuant to the repairing covenant and its obligation to repair any damage to the demised premises caused by it. The landlord further argues that without the works, the premises cannot properly be used as a book shop. Tomes disagrees claiming that the repairing covenant covers only cosmetic facade and the installation of steel reinforcement cannot be characterized simply as a cosmetic enhancement but one that requires structural repair. Tomes further refuted the move of the landlord for rent review as the review was not timely initiated within the period specified in the leasehold thus estoppel set in. Tomes suspects that the persistence of the landlord to ascribe fault against it is brought about by his recent acquisition of the controlling share in Volumes Limited (Volumes for brevity), a specialist book-seller which needs new retail premises. It would appear that the landlord wants to get Tomes out of the way to install Volumes in the premises

Transforming Complaints into Commitments Essay Example | Topics and Well Written Essays - 1750 words

Transforming Complaints into Commitments - Essay Example I, therefore, came up with a plan that I believed would be the best solution. My plan was to call a Towing company whenever I found a car parked in my space. I was, however, concerned about my safety and that of my property. I assumed that if I call the towing company to tow people’s cars away, they might get angry and vandalize my car, especially because of the expensive tow bills. The people might also turn their anger on me. I developed a different way to deal with the issue. My solution was to talk to the apartment management to place a bigger sign telling people that the parking space was reserved. I noticed that some did not notice that it was a reserved parking space. I am also willing to politely tell people to stop parking on other people’s spaces whenever I see them. Course concepts used are values and assumptions. Values are my beliefs on what is right or wrong. My values guided my decision making since it made me think of solving the problem. I developed an improved way of dealing with the situation. Because of my values, that is, the other people should respect my rights, I thought of involving the towing company. My values influenced my assumptions for I thought of the effect the expense of towing a car would have on their owners. My values influenced my decision. I believe in what is right, but I also value peace. Towing the cars could solve the problem, but it could create another more serious problem. The people could get angry, and this could put my life in danger. They could even decide to vandalize my car. I, therefore, thought of more modest risk. This was communicating with the people to let them know about my parking space. This would yield almost the same results, but was a more modest way. I used assumptions to guide my decision making on a modest way to deal with the issue. I first thought of a solution which would work, which was to call a
