How to Water a Tree and When You Shouldnt

How to Water a Tree and When You Shouldn't Few tasks for homeowners are more complicated than knowing if, when and how to water a landscape tree. Much of it depends on the type of tree, your climate, current weather conditions, and a host of other variables. A watering schedule that works well for one tree species in one region of the country can be disastrous for a different tree species or in a different climate region.   Water is the single most essential resource for a trees survival and growth, far more important than fertilizing, disease and pest control, or any other biological need.  Most of us understand the need to water trees during dry times, but what we often forget is that a tree can also be harmed by too much water. Unfortunately, the symptoms for a water-starved tree can appear to be the same as symptoms caused by water-logged tree roots. A tree that is beginning to wilt may be shutting down because too much water has introduced a vascular fungal disease into the roots, for example. In many cases, a homeowner then responds by watering more frequently and more heavily, which can lead to much bigger problems.   Symptoms for both under-watering and over-watering can be the appearance of wilted and scorched leaves. Both conditions can prevent tree roots from effectively transporting water to the top of the tree and the tree will react by wilting. In addition, too much tree water can also shut down sufficient oxygen to the roots. Some tree species can handle wet feet but many trees can not. Always read up on your tree species and learn what it wants and doesnt want in terms of its environment and watering needs.   Trees known for vibrant fall color will show disappointing color in the fall if you overwater them. Bright leaf color is triggered by the naturally dry conditions that occur in the early fall, and a tree that receives too much water during this time of year may respond by disappointing you with its leaf color. To maximize the fall display, keep the tree well-watered during the main part of the growing season, but withhold water in the late summer and early fall. Once the trees leaves have fallen, do water the soil adequately, because you want good soil moisture to be present in the ground going into winter.   How To Water a Tree Supplemental watering during drought conditions can prevent tree decline, pest problems, and non-recoverable damage to tree roots and the  canopy. Young trees recently planted in the landscape and certain drought-prone species need regular watering during dry periods. This essentially means that most trees that have seen no rainfall in a given week should get a hand watering. This is not a hard and fast rule, though, because many native species are adapted to local conditions and may not need extra watering. Consult with a nursery specialist or a member of your state universitys Extension service to learn the needs of your trees.   Depending upon soil texture, the density of water-competing plants found around the tree, daily temperatures, and recent rainfall amounts, about one inch of water per week should keep a tree healthy. Trees should be watered once or at most twice a week in the growing season if there has been no significant rainfall. A few slow, heavy (high-volume) waterings are much better than many short, shallow waterings, because long, infrequent waterings encourage the tree to send out deep, robust roots. Frequent shallow waterings will encourage the tree to rely on shallow, weak roots, which is not to the long-term benefit of the tree.   However, to say that a tree needs deep watering does not mean dumping huge quantities of water on it in within a few minutes. When this is done, much of the water simply sinks through the soil layer past the trees roots and is never taken up by the roots at all. The best deep watering is a slow watering left in place for an hour or so. Turning a garden hose on so it produces a small trickle and leaving the end of the hose a foot or so away from the trunk is ideal. Another excellent method for watering young trees is to use one of the tree-watering bags available. Made from dense flexible plastic or rubber, these bags fit around the lower tree trunk, and when they are filled with water, they allow a slow, steady trickle of water to run down into the earth. This provides the deep, slow watering that is ideal for trees.   All landscape trees should be properly mulched, which means blanketing the area directly under the tree canopy with a 2- or 3-inch layer of organic material, such as shredded wood or compost. This layer of mulch will cool the soil and keep moisture trapped in place. But dont pile the mulch up against the tree trunk, because this will encourage pests and fungal diseases.   Dont Over-Water a Tree! As mentioned, if the trees leaves look wilted or scorched even though you have faithfully been watering, its quite possible that there is too much soil moisture for the tree to handle. This can be a problem in landscape with automatic watering systems that apply water by timer even during weeks when rainfall amounts have been good. The best way to check for wet soil is to dig down 6 to 8 inches and feel the soil. The soil should be cool and slightly moist but not soaking wet. Examining the soil with your hands may also tell you much. You should be able to press most non-sandy soils into a ball with your hands and have it stay together without falling apartthis indicates proper soil moisture.  If the soil ball falls apart when squeezed, then the soil may not have sufficient moisture. If the soil ball you just made will not crumble when rubbed, you either have clay soil or soil that is too wet to crumble. This is an indication of too much water, so watering should be stopped. Neither loose sandy soils nor dense clay soils are ideal for growing most trees, although you may be able to find species well adapted to these soil conditions. In general,  sandy soils will adequately support trees adapted to droughty, low-moisture conditions, while clay soils will work well with trees known to thrive in wet, boggy environments.

Water Chemistry Definition and Properties

Water Chemistry Definition and Properties Of all the molecules in the universe, the one most important to humanity is water: Water Definition Water is a chemical compound consisting of two hydrogen atoms and one oxygen atom. The name water typically refers to the liquid state of the compound. The solid phase is known as ice and gas phase is called steam. Under certain conditions, water also forms a supercritical fluid. Other Names for Water The IUPAC name for water is, actually, water. The alternative name is oxidane. The name oxidane is only used in chemistry as the mononuclear parent hydride to name derivatives of water. Other names for water include: Dihydrogen monoxide or DHMOHydrogen hydroxide (HH or HOH)H2OHydrogen monoxideDihydrogen oxideHydric acidHydrohydroxic acidHydrolHydrogen oxideThe polarized form of water, H OH-, is called hydron hyroxide. The word water comes from the Old English word wà ¦ter  or from the Proto-Germanic watar or German Wasser. All of these words mean water or wet. Important Water Facts Water is the main compound found in living organisms. Approximately 62 percent of the human body is water.In its liquid form, water is transparent and nearly colorless. Large volumes of liquid water and ice are blue. The reason for the blue color is the weak absorption of light at the red end of the visible spectrum.Pure water is flavorless and odorless.About 71 percent of the Earths surface is covered by water. Breaking it down, 96.5 percent of the water in the Earths crust is found in oceans, 1.7 percent in ice caps and glaciers, 1.7 percent in ground water, a small fraction in rivers and lakes, and 0.001 percent in clouds, water vapor, and precipitation.Only about 2.5 percent of the Earths water is fresh water. Nearly all of that water (98.8 percent) is in ice and ground water.Water is the third most abundant molecule in the universe, after hydrogen gas (H2) and carbon monoxide (CO).The chemical bonds between hydrogen and oxygen atoms in a water molecule are polar covalent bonds. Water readily forms hydrogen bonds with other water molecules. One water molecule may participate in a maximum of four hydrogen bonds with other species. Water has an extraordinarily high specific heat capacity [4.1814 J/(g ·K) at 25  Ã‚ °C] and also a high heat of vaporization [40.65  kJ/mol or 2257  kJ/kg at the normal boiling point]. Both of these properties are a result of hydrogen bonding between neighboring water molecules.Water is nearly transparent to visible light and the regions of the ultraviolet and infrared spectrum near the visible range. The molecule absorbs infrared light, ultraviolet light, and microwave radiation.Water is an excellent solvent because of its polarity and high dielectric constant. Polar and ionic substances dissolve well in water, including acids, alcohols, and many salts.Water displays capillary action because of its strong adhesive and cohesive forces.Hydrogen bonding between water molecules also gives it high surface tension. This is the reason why small animals and insects can walk on water.Pure water is an electrical insulator. However, even deionized water contains ions because water unde rgoes auto-ionization. Most water contains trace amounts of solute. Often the solute is salt, which dissociates into ions and increases the conductivity of water. The density of water is about 1 gram per cubic centimeter. Regular ice is less dense than water and floats on it. Very few other substances exhibit this behavior. Paraffin and silica are other examples of substances that form lighter solids than liquids.The molar mass of water is  18.01528  g/mol.The melting point of water is  0.00  Ã‚ °C (32.00  Ã‚ °F; 273.15  K). Note the melting and freezing points of water may be different from each other. Water readily undergoes supercooling. It can remain in liquid state well below its melting point.The boiling point of water is  99.98  Ã‚ °C (211.96  Ã‚ °F; 373.13  K).Water is amphoteric. In other words, it can act as both and acid and as a base. References Braun, Charles L.; Smirnov, Sergei N. (1993-08-01). Why is water blue?.

Death Penalty in New York State Research Paper Example | Topics and Well Written Essays - 2000 words

Death Penalty in New York State - Research Paper Example George Kendall is documented as being the first man to be officially put to death in colonized America by the state in 1608. Since then over 20,000 accused criminals have been executed in America for a variety of offenses ranging from murder to property crimes. The inclination of jurists to award the death penalty almost at will in the early part of American history was partly influenced by the lack of penitentiaries and an organized prison system. Execution was seen as the primary method to protect society from subversive and anti-social elements. Capital punishment was also employed as a means to control the slave population and many disproportionate capital sentences were imposed on slaves of African descent when the same would not have applied to Caucasians. In New York attempted murder or rape were capital crimes only when committed by slaves (Acker, 2003). The colony of New York was originally under the control of the Dutch albeit without any formal legal system. The death pena lty was practiced and administered in an arbitrary and reckless manner in those early days. It was often the case that when the culprit could not be identified, the accused would have to â€Å"draw lots† in order to determine who would be executed. The arrival of the British to New York saw the implementation of a penal code, where the death penalty was still a frequently awarded punishment. In 1741, 18 white colonials and 13 slaves were sentenced to death by burning at the stake. However, the new British legal system also contained a clemency clause. An individual on death row was eligible for a pardon if they agreed to leave the colony or chose to enlist in the armed forces. As a result of this provision during the 18th century 51% of individuals sentenced to death in New York were eventually pardoned (Heller, 2008). The death penalty statute continued to evolve after the formation of the United States of America and the subsequent imposition of its new legal system. In 188 8, The New York State Assembly passed a statute which would see it become the first state to directly administer the death penalty. According to the statute the death penalty was mandatory for extremely grave and depraved offences. The law also called for a new method of execution, which was â€Å"death by electricity†. William Kemmler became the first man to be executed by means of electric chair, in 1890. Up until the 1930’s the State of New York was responsible for more executions than any other state. During this period state statutes were amended in order to encompass a wider array of crimes that could be punishable by death. The most significant of these was kidnapping, influenced greatly by the â€Å"Lindbergh baby’ saga which dominated headlines during this period. Due to these amendments juries were also instructed to give sentencing recommendations in trials where the convicted were eligible for capital punishment (Heller, 2008). Rise of Abolitionist Movement Throughout the colonial era and up until the mid 20th century voices that were opposed to the death penalty slowly began to grow in strength. By the 18th century many American’s had begun to question the application of the death penalty for crimes that were petty and trivial in nature. Dissenting voices could also be heard in

The Impact of Social Media and Viral Marketing on the Film Industry Essay

The Impact of Social Media and Viral Marketing on the Film Industry - Essay Example Different network websites focus on different issues which include books, general, film, music, community, health, education and tourism. A Marketing technique similar to a self-replicating virus through an internet, using social networking or other internet applications for creating or increasing brand value is called as viral marketing. According to St-Amant (2012 p. 1), a patient principal uses viral marketing for stronger results. This paper seeks to analyse and make recommendations as to how the managers of the film industry can respond to the issues relating to social media and viral marketing considering their impacts on the industry with justification for recommendations. Evolution of social media over a period of time indicates how businesses have made use of it for marketing. Understanding the developments taken place in social media is important for evaluating its impact and reorienting our strategies in line with technological changes. Evolution of social media Once, word of mouth was the greatest marketing mantra. Also, rumour gets thicker as it spreads. In social media, it can become a mania or rage due to viral power in self-replicating techniques, if the strategy is logical and sound. According to Hinz et al (2012 p. 12) ‘hubs and bridges are key to the diffusion of viral marketing campaigns.’ Social media has broken the concept of ‘time’ in marketing perspective. Time and place are no longer the prohibiting factors in viral marketing in social media. The Web 2.0 phenomenon made collaboration with the customers easier.... 12) ‘hubs and bridges are key to the diffusion of viral marketing campaigns.’ Social media has broken the concept of ‘time’ in marketing perspective. Time and place are no longer the prohibiting factors in viral marketing in social media. The Web 2.0 phenomenon made collaboration with the customers easier. A single new contact brings all of its other contacts to the business in viral marketing that could be compared with infection through a web of the network with endless permutations and combinations. ‘Going viral is like a calculus function mixed with the element of randomness – Brad Hines.’ (Torkildson, 2012) Viral marketing’s impact on brand or content propagated in social media can be positive or negative. The absence of copy rights or patent laws for the contents propagated in social media attracts people and viewership is encouraged. Monetisation of viewership becomes easier where there is surge in demand for content. The Ou tdated brand of Old Spice has been revived by P&G in their viral marketing strategy for the product. The Responses to the Old Spice marketing strategy ‘topped 6 million total views and 60 000 Tweets in the first 24 hours on YouTube’ (Mills, 2012 p. 165) Similarly, negative impact affects the business severely. In a way, it increases the level of corporate social responsibility among the companies as the customers’ views on corporate practices converge at a faster pace that forces the companies to review their strategies more in line with public expectations. ‘Greenpeace supporters were so successful at flooding Nestle's Facebook page last year that the Kit Kat maker's social media rep publicly lashed out’ (CNN Money, 2011). Social media is an evolving theme with a very short history. Releasing

A Conservative Argument against Stem Cell Research Essay -- Stem Cell

A Conservative Argument against Stem Cell Research For the past few years stem cell research has been a widely debated topic; however, former President Clinton?s stance?allowing federal money to be spent on tightly controlled stem cell research?lead to intense debates over federal funding for stem cell research. There are four ways of obtaining stem cells, which are taken from embryos that are approximately one week old. They are using unwanted embryos from fertility clinics, embryos from aborted fetuses, cloned embryos, and embryos created for research purposes. Stem cells can also be taken out of adult bone marrow, but scientists do not think that adult stem cells hold as much medical potential. Conservatives are against federal funding for stem cell research because they feel that by doing such the government would be contributing to ?murder.? This idea is rooted in the religious beliefs, which include the belief that life begins at conception, held by conservatives. However, liberals support federal funding for the resear ch of embryos because they question whether embryos are full human beings and believe the research could expedite potential medical breakthroughs. The editorial, ?Stem Cells and the Logic of the Nazis,? appeared in the September 3, 2000 issue of the Los Angeles Times. Even though the Los Angeles Times, a widely distributed newspaper, has a slightly liberal slant, this editorial displays a strongly conservative view on stem cell research. Thus, the author of the editorial has to be very cautious in the tone that he uses in order not to offend liberal readers. George Weigel, the author of this editorial, picks apart what he sees as the fallacious argument of Michael Kinsley, a well-known libe... ...vative which is supported by the fact that Weigel is a senior fellow at the Ethics and Public Policy Center. Since, he is writing to an audience with a vast range of political viewpoints and he must be very careful not to be too aggressive in the tone he uses. Weigel begins this article with very basic logic and then progresses to logic by analogy with incorporated pathos. This is a very effective method for him with conservative readers because he is successfully able to transfer emotions about other subjects into emotions about stem cell research. He also uses logic by cause and effect, which in this case is designed to create fear in the reader: fear that history will repeat itself.

Kit Kat analysis Essay

Introduction Nestle has won, after 7 years, trademark battle against Cadbury over the four-fingered shape of the Nestle product – KitKat. Nestle is the Swiss multinational company in snack food, health-related goods industry. Nestle is the largest food company in the world by its revenue. Their products include baby food, bottle water, cereals, coffee, chocolate bars and many others. The most popular products are Nespresso, Nescafe, KitKat, Maggi and Nesquick. Nestlà ©Ã¢â‚¬â„¢s largest competitors are Kraft Foods, Unilever and Mars incorporated. Cadbury is a British company and best known for its confectionary products. Cadbury was established as retailer of tea, coffee and drinking chocolate. The most popular products are Dairy Milk chocolate, the Crà ¨me Egg and Roses selection box. Cadbury`s main competitors are Jacobs Suchard, Nestle and Mars Incorporated. Kit Kat is one of the Nestle popular products which was invented in 18th century by Rowntree`s of York (than was acquired by Nestle). Kit Kat has unique four-fingered shape, which makes it recognizable as the product of Nestle. The following case is all about Kit Kat`s shape and weather Nestle can have a trademark on the shape (not the name – which is more common). Nestle and Cadbury were involved in a lawsuit over the four finger KitkKat`s shape. Nestle -the world’s biggest food company, has succeeded in stopping rivals from copying the shape of the four-fingered bar after a seven-year legal battle.1 Neste had registered shape of KitKat as a trademark in 2006 but Cadbury appealed against this application. In my paper I will discuss claim over trademark between Nestle and Cadbury, and the case status. This case is unusual in the way of concerns; the focus is not on the trademark name, but a trademark shape. By implying that we would not see an infringement in the case, but trademark ruling. KitKat  shape The case of KiKat, as mentioned above, is an unusual trademark wrangle between Cadbury and Nestle over shape of chocolate bar. Neste had introduced Kit Kat in 1935 and had registered KitKats shape in 2006. Cadbury applied to invalidate the registration on the basis of shape, since one company cannot monopolize shape. The office of harmonization of the Internal Market, which registers EU Community Trade Marks, allowed 3d – shape trademarks2 for sweets, bakery, biscuits, cakes and waffles in 2006, but lacked in application for chocolate, candy and confectionery. Few years later Cadbury disputed Nestle trademark to Cancellation Committee because of the mark was for a 3d-shape rather than over a name. The Cancellation Committee declared the Nestle trademark invalid. Originally, Cadbury had won its claim. Nestle had appealed and trademark regulators overturned decision after. Regulators reached new decision: as the four-fingered shape Kit Kat was exclusively associating as Nestle product. Nestle had provided evidence of using that shape for long period of time and had provided evidence of KitKat shape was exclusively associated with Nestle across the world and had gathered enough evidence to proof that Nestle had educated the public that chocolate bar with fingered shape is originated by Nestle. Case in flash In 2007 Cadbury filed a declaration of invalidity against Nestle, the request was directed against all the good covered by Nestle. Cadbury had thought that trademarking shape of the chocolate bar is a limitation of choice for consumers. In the proceedings parties submitted their observations and supporting documents. Nestle had submitted the following evidence to proof the KitKats shape was exclusively associated with them3: Overview of the worldwide sales volume, turnover and advertising cost for the 1995-2007 years; Set of documents related for a Kit Kat consumption in the United Kingdom; Promotional leaflet in which history of KitKat presented ; Compilation of the launch dates of the four fingered chocolate bar in the European Union (Uk 1937, Italy 1960, Austria 1988 and etc.); Marketing research, concerning market share; List of commercial and CD (containing examples); Nestle internal financial figures, market share, advertising expenses . Even though trademark is commonly the mark, motto or device, the shape of a product is considered trademark too, because consumers can identify the source of were the product originated. By submitting above evidence it was clear that trademark elements had been met: Kit Kat`s shape is distinctive – sufficient for consumers to identify manufacturer, suggestive – its clear for consumers that four-fingers shape is KitKat taste and even fanciful – Kit Kat had been massively invented by Nestle. Conclusion: Cadbury now has to decide whether or not it wants to appeal against the decision. The latest ruling over KitKat`s shape will prevent similar companies from producing similar bars of chocolate; it is now exclusively associated with Nestle. It was significant win for Nestle, since the four-finger shape became synonymous with its product. Nestlà ©Ã¢â‚¬â„¢s case follows history of legal battles between the two companies. In 2012 Cadbury secured trademark rights to the purple color used on its packaging. Intellectual property office had awarded particular shade of purple to chocolate bars and drinking chocolate to Cadbury. Nowadays a lot of trademark cases are existing. Analyzing the importance of trademark, we can conclude that companies are very concerned of being exclusive and protecting its intellectual property. A lot of trademark cases exist because of technology progress, it is so much easier today to advertise online, have the market research done online, surveying the product satisfaction and etc. Since multimedia is our everyday routine, rivals can easily caught the consumer’s attention (by using already existing trademark) or converse the existing relationship with the product.

Advanced French Verb Conjugation

Conjugation refers to the five possible inflections of a verb: Person, Number, Mood, Tense, and Voice. Once youve made a choice from each of these five, you have a conjugation or inflection. For example:Verb - parlerPerson - first personNumber - singularMood - indicativeTense - presentVoice - active je parleVerb - allerPerson - third personNumber - pluralMood - subjunctiveTense - presentVoice - active quils aillentWhen conjugating a French verb, the first things to figure out are the tense and mood, which work hand-in-hand. All moods have at least two tenses (present and past) out of the possible 8 (only the indicative has all 8). The verb timeline lists moods horizontally and tenses vertically.The indicative is the most common mood and is normally not stated. When you talk about the passà © composà ©, the imperfect, or the present tense, for example, you mean of the indicative mood. Its only with other moods like subjunctive and conditional that the mood is stated explicitly.All m oods have a present tense, which is again not made explicit except in the indicative and participle (parentheses indicate what normally goes unsaid): present (indicative)(present) conditional(present) subjunctive(present) imperative(present) infinitivepresent participle So for example, the imperfect (indicative) and the imperfect subjunctive are two different moods of the same tense. On the other hand, the (present) conditional and the past conditional are two different tenses of the same mood. The verb timeline can help you understand this, because it lines up moods and tenses so that you can see how they all fit together. X axis Y axis verb form and basis of individual conjugations. Voilà   - now that you understand the basics of French verb conjugation, study the lessons on individual tenses and moods (linked from the verb timeline) to learn more, or visit my French grammar glossary. Tricky Subjects When you understand subject pronouns, tenses, moods, and how to conjugate  French verbs, youre in great shape. There are however some grammatical subjects which make conjugation a bit more difficult. Multiple Subjects When you have more than one subject, you have to figure out which  subject pronouns  would replace that group and then conjugate the verb accordingly. For example,  toi et moi  would be replaced by  nous, as would  David et moi.  Toi et lui  and  Michel et toi  would be replaced by  vous.  Lui et elle  or  Marc et Anne  would be replaced by  ils. The trick is to make this replacement in your head without actually saying it out loud, as denoted by the (parentheses):  Ã‚  Ã‚  Toi et moi (nous) pouvons le faire  Ã‚  Ã‚  You and I can do it  Ã‚  Ã‚  Paul, Marie et moi (nous) mangeons  Ã‚  Ã‚  Paul, Marie, and I are eating  Ã‚  Ã‚  Toi et elle (vous) à ªtes en retard  Ã‚  Ã‚  You and she are late  Ã‚  Ã‚  Sophie et toi (vous) devez partir  Ã‚  Ã‚  You and Sophie have to leave  Ã‚  Ã‚  Luc et sa femme (ils) sont arrivà ©s  Ã‚  Ã‚  Luc and his wife have arrived  Ã‚  Ã‚  Lui et elle (ils) lisent beaucoup  Ã‚  Ã‚  He and she read a lot Subject +Object Pronoun In a construction with an  object pronoun, usually  nous  or  vous, there is sometimes a tendency to conjugate the verb according to it, rather than to the  subject pronoun, because the object directly precedes the verb. Though this tends to be a careless mistake made orally rather than a lack of understanding, its included here just as a little reminder.  Ã‚  Ã‚  Je vous ai donnà © la liste  Ã‚  Ã‚  I gave you the list  Ã‚  Ã‚  xx Je vous avez donnà © la liste xx  Ã‚  Ã‚  Vous nous avez menti  Ã‚  Ã‚  You lied to us  Ã‚  Ã‚  xx Vous nous avons menti xx Cest... qui The construction  cest  Ã‚  stressed pronoun  Ã‚  qui  makes many people - including at times native French speakers - want to use the third person singular verb conjugation because of  qui. But this is incorrect; in fact, the conjugation has to agree with the pronoun.  Ã‚  Ã‚  Cest moi qui ai gagnà ©Ã‚  Ã‚  Ã‚  Its me that won  Ã‚  Ã‚  xx Cest moi qui a gagnà © xx  Ã‚  Ã‚  Cest vous qui avez tort  Ã‚  Ã‚  Youre the one whos wrong  Ã‚  Ã‚  xx Cest vous qui a tort xx  Ã‚  Ã‚  Cest nous qui allons le faire  Ã‚  Ã‚  Were the ones who are going to do it  Ã‚  Ã‚  xx Cest nous qui va le faire xx Pronoun + Qui Similar to the  cest... qui  construction is a subject or  demonstrative pronoun  Ã‚  qui. Again, the  qui  makes people want to use the third person singular, but once again the conjugation has to agree with the pronoun.  Ã‚  Ã‚  Vous qui avez mangà © pouvez partir  Ã‚  Ã‚  Those of you who have eaten may leave  Ã‚  Ã‚  xx Vous qui a mangà © pouvez partir xx  Ã‚  Ã‚  Ceux qui veulent aider doivent me voir  Ã‚  Ã‚  Those who want to help need to see me  Ã‚  Ã‚  xx Ceux qui veut aider doivent me voir xx  Ã‚  Ã‚  Je cherche celles qui à ©tudient  Ã‚  Ã‚  Im looking for the ones who are studying  Ã‚  Ã‚  xx Je cherche celles qui à ©tudie xx Collective Subjects Collective subjects can take the third person singular or plural:   Ã‚  Ã‚  Un tas de fleurs sont mortes / Un tas de fleurs est mort  Ã‚  Ã‚  A bunch of flowers died  Ã‚  Ã‚  Un grand nombre de livres ont disparu / Un grand nombre de livres a disparu  Ã‚  Ã‚  A large number of books disappeared Adverbs of Quantity Adverbs of quantity  take the third person singular or plural, depending on the number of the noun that follows:   Ã‚  Ã‚  Beaucoup dà ©tudiants sont arrivà ©s  Ã‚  Ã‚  A lot of students have arrived  Ã‚  Ã‚  Peu de pluie est tombà ©e  Ã‚  Ã‚  Little rain fell  Ã‚  Ã‚  Combien de livres y a-t-il  ?  Ã‚  Ã‚  How many books are there?Also see ...dentre... below. Indefinite Pronouns Indefinite pronouns  always take a third person conjugation (either singular or plural, depending on the number of the pronoun).  Ã‚  Ã‚  La plupart a dà ©cidà ©Ã‚  Ã‚  Ã‚  Most have decided  Ã‚  Ã‚  Plusieurs sont perdus  Ã‚  Ã‚  Many are lost  Ã‚  Ã‚  Tout le monde est là  Ã‚  Ã‚  Ã‚  Everyone is thereAlso see ...dentre... ...dentre... When an  adverb of quantity  or  indefinite pronoun  is followed by  entre  Ã‚  personal pronoun, many non-native French speakers (including myself) want to conjugate the verb according to the personal pronoun. But this is incorrect - in this construction, the verb has to be conjugated to agree with what comes before  entre, not what comes after.  Ã‚  Ã‚  Certains dentre vous ont oublià ©Ã‚  Ã‚  Ã‚  Some of you forgot  Ã‚  Ã‚  xx Certains dentre vous avez oublià © xx  Ã‚  Ã‚  Beaucoup dentre nous sont en retard  Ã‚  Ã‚  Many of us are late  Ã‚  Ã‚  xx Beaucoup dentre nous sommes en retard xx  Ã‚  Ã‚  Chacun dentre vous peut le faire  Ã‚  Ã‚  Each one of you can do it  Ã‚  Ã‚  xx Chacun dentre vous pouvez le faire xx
