Abstract on Rose diseases Essays - Podosphaera, Powdery Mildew abstract on Rose diseases title = abstract on Rose diseases Disease Control Multi-Purpose Fungicide Daconil 2787 Plant Disease Control This product is widely used for broad spectrum disease control on lawns, ornamentals and listed fruits and vegetables. Controls many foliar diseases such as: rust, black spot, leaf spot, blights, anthracnose and powdery mildew as listed on the label. Also controls conifer diseases and lawn diseases such as brown patch, red thread, rust and dollar spot. Can be mixed with insecticides as specified on the label to make a multi-purpose spray. WHAT IS POWDERY MILDEW? Powdery Mildew looks like white fuzzy powder that accumulates on leaves and stems predominantly in spring, and again to a lesser degree in fall. It is actually a fungus that is spread by millions of microscopic spores. It imbeds itself into tender new growth and feeds on the sap of the plant. By the time the naked eye can see the white 'powder,' it has already invaded the plant tissue and is feeding and reproducing at a rapid pace. As it spreads itself on the surface, it eventually kills the cells of the plant leaf, leaving the leaf rippled and curled. Mildew spores are everywhere in the garden - in the air, the soil, on debris and on plant surfaces - ready to sprout when the environment is just right. Warm days (50-80F) and cool nights with elevated humidity and resultant dew provide ideal conditions. Though humidity promotes fungal growth, it grows on DRY plant surfaces, unlike blackspot which requires immersion in water for about seven hours in order for infection to take place. Tender new growth needs a chance to 'harden' and develop its waxy coating that provides somewhat of a barrier to fungal growth. Therefore, the rosarian must provide protection for new spring growth on a weekly basis. CONTROLLING POWDERY MILDEW Controlling mildew doesn't have to mean spraying the planet into oblivion. It includes plant genetics, cultural practices and something as simple as WATER. GENETICS: While rose hybridizers are chastised for breeding OUT fragrance, what they are trying to accomplish is breeding IN disease resistance. For scientific reasons beyond explanation here, rose genes don't contain both features - it's one or the other. Hence, you can expect either fragrant roses with little disease resistance, or clean plants with little fragrance. Plants with glossy or waxy leaves are less susceptible to mildew, as the leaf surface is harder for spores to penetrate. Rugosas naturally possess a high degree of disease and pest resistance. Where mildew is a constant problem, the choice in plantings can help prevent the need for extensive maintenance. CULTURAL PRACTICE: Planting bushes with sufficient space between them and away from walls and fences will provide good air circulation which reduces the chances for mildew. The annual pruning event plays a major role in disease prevention. Stripping leaves from the bush at pruning time, and cleaning up debris in the garden contribute to a cleaner environment. Dormant spraying will at least wipe out last year's spores, leaving only this year's to contend with. Keeping the centers of the bush open during the growing season will aid air circulation. Avoid the use of other plant materials with high mildew susceptibility, such as euonymus and tuberous begonias. Apply a thick layer of mulch in early spring to cover spores in the soil that may have wintered over. WATER is perhaps the most misconceived element surrounding powdery mildew. Many gardeners still subscribe to the belief that you should NEVER get rose foliage wet. On the contrary, a high-pressure spray of water will remove mildew spores that haven't imbedded themselves yet, and prevent them from germinating. Higher incidence of mildew during periods of rain is caused by the moisture in the air and soil - increasing the humidity that promotes mildew - not by water on the leaves. Similarly, watering early in the day will allow the soil surface to dry out a bit before the cool night temperatures arrive, reducing humidity from moist soil. PREVENTION IS THE ONLY CURE Once powdery mildew is apparent to the eye, it can't be eradicated. It simply must be prevented. Prevention is achieved by coating the plant tissue with something that provides a barrier to prevent fungus from gaining a foothold and invading the plant tissue. Growth is so rapid in spring that the leaves unfolding THIS week won't be protected by what you sprayed LAST week. This is the reason you find application schedules of every 7-10 days on most fungicides, and

Lyda Newman Invents Vented Hair Brush

Lyda Newman Invents Vented Hair Brush African-American inventor Lyda D. Newman patented a new and improved hairbrush in 1898  while living in New York. A hairdresser by trade, Newman designed a brush that was easy to keep clean, durable, easy to make and provided ventilation during brushing by having recessed air chambers. In addition to her novel invention, she was a womens rights activist.   Hairbrush Improvement Patent Newman received patent #614,335 on Nov. 15, 1898. Her hairbrush design included several features for efficiency and hygiene. It had evenly spaced rows of bristles, with open slots to guide debris away from the hair into a recessed compartment and a back that could be opened at the touch of a button for cleaning out the compartment. Women's Rights Activist In 1915, Newman was mentioned in local newspapers for her suffrage work. She was one of the organizers of an African-American branch of the Woman Suffrage Party, which was fighting to give women the legal right to vote. Working on behalf of her fellow African-American women in New York, Newman canvassed her neighborhood to raise awareness of the cause and organized suffrage meetings in her voting district. Prominent white suffragists of the Woman Suffrage Party worked with Newmans group, hoping to bring voting rights to all of New Yorks female residents. Her Life Newman was born in Ohio around 1885. Government censuses of 1920 and 1925 confirm that Newman, then in her 30s, was living in an apartment building on Manhattans West Side and was working as a familys hairdresser. Newman lived much of her adult life in New York City. Not much else is known about her private life. Hairbrush History Newman did not invent the hairbrush, but she did revolutionize its design to resemble the brushes in use more today. The history of the first hairbrush begins with the comb. Found by archaeologists at Paleolithic dig sites around the world, combs date back to the origins of human-made tools. Carved from bone, wood, and shells, they were initially used to groom hair and keep it free of pests, such as lice. As the comb developed, however, it became a decorative hair ornament used to display wealth and power in countries including China and Egypt.   From ancient Egypt to Bourbon France, elaborate hairstyles were in vogue, which required brushes to style them. The hairstyles included ornate headdresses and wigs that were used as displays of wealth and social status. Because of their primary use as a styling tool, hairbrushes were an indulgence reserved exclusively for the wealthy. As late as the 1880s, each brush was unique and carefully handcrafted- a task that included carving or forging a handle from wood or metal as well as hand-stitching each individual bristle. Because of this detailed work, brushes were usually bought and gifted only on special occasions, such as weddings or christenings, and cherished for life. As brushes became more popular, brush makers developed a streamlined manufacturing process to keep up with demand.

Soft Systems Methodology and Activity Theory (System Thinking) Essay

Soft Systems Methodology and Activity Theory (System Thinking) - Essay Example Whereas AT inspires theoretical thought in many disciplines – psychology, culture, information systems, education, and management, disciplines that generally apply strategies involving human activity. Many researchers have cited AT as being holistically rich when it comes to understanding how humans conduct activities together with the aid of advanced tools in very dynamic and intricate settings (Adebowale, 2010). The aim of this paper is to critically evaluate how soft systems methodology and activity theory can be used to understand organisational problems. As part of this objective, the essay will also compare and contrast the two approaches and discuss relative strengths and weaknesses. SSM has undergone various modifications and revisions to become more practical, flexible, and relevant to different disciplines and organisational problems. However, SSM’s suitability to various fields has remained the most important asset, one which has not required numerous modifications to remain relevant (Bell, 2013). In addition, SSM is currently used by people who lack a technical background but want to solve complex organisational problems. At the moment, SSM is applied in several main organisational settings or disciplines. For example, in performance evaluation, it is used to develop performance measures, quality assurance processes, and to monitor the organisation. In education, it is used in defining course designs, training requirements, causes of absenteeism and to analyse language teaching. It is also used in project management, personal life decisions, risk management processes, organisational strategy, and industrial tribunal cases (Bozalek and Ambi, 2014). The first stage often involves recognising, exploring and defining the problem in some way. Firstly, the organisation must decide what it is actually investigating. At this stage,

Louisiana Purchase - Essay Example With the power of France and Napoleon Bonaparte continually rising, Spain signed with France into the Treaty of San Ildefonso which included ceding Louisiana back to France. President Thomas Jefferson grew wary of protecting the interests in New Orleans and the Mississippi as the previous treaty with Spain is in the brink of being revoked. He actively sought to obtain New Orleans and authorized $10 million for its purchase. Luckily, Napoleon’s interest in the Americas was thwarted and he settled his eyes on Europe. Bonaparte sent Talleyrand and Barbe-Marbois who negotiated with Robert Livingston and James Monroe in 1803 for the purchase of the entire Louisiana for $15 million (The Museum Gazette). This was an important milestone in United States history and highlighted the presidency of Jefferson. â€Å"Louisiana doubled the size of the United States literally overnight, without a war or the loss of a single American life, and set a precedent for the purchase of territory† (The Museum Gazette). This became a precedent for the possibility of acquiring territories not only within the continent but including the Pacific. The purchase had oppositions, mainly coming from New England Federalists who felt they were losing grips of their influence because of the expansion. Nevertheless, it was considered as one of the greatest bargains in real estate considering the vastness and size of Louisiana in proportion to its purchase value (Sage

The History of Palestine :: essays research papers

The History of Palestine Introduction Since the second Abbasid period, which commenced after the mid of the third Hijri century, the Islamic Caliphate State was progressively in weakening till it was broken down into three Caliphates instead of one. The Abbasid Caliphate was established in the East; the Fatimid Caliphate in Egypt, parts of North Africa and Syria, and the Umayyad Caliphate in Andalus. The Crusades took place under these circumstances. Top -------------------------------------------------------------------------------- The political map of the region before the Crusades Forty years before the Crusades, the Turkish Saljuks had succeeded in dominating Baghdad and took over the rule under the nominal Abbasid Caliphate. The Saljuks had managed to dominate over larger parts of Persia, northern Iraq, Armenia and Asia Minor around 1040 CE. The Saljuk ruler, Toghrol Bic, dominated over Bain 1055 CE. The Saljuks spread their rule over the Byzantines in Asia Minor. On 19 August 1071 CE, the Malathkard battle, under the command of the Saljuk ruler Alb Arsalan, took place, and a catastrophe befell the Byzantines till the end of the eleventh century CE. In 1071 CE, the Saljuks seized most of Palestine except for Arsout, and dismissed the Fatimid dominion from it. The Saljuks expanded their dominion to include most of Syria. In 1092 CE (485 H [Hijra]), the Saljuk Sultan Malikshah passed away, thereby breaking down the Saljuks' dominion and launching many long and severe battles among them over the dominion and power. In 1096 CE, their rule was divided into five kingdoms: Sultanate of Persia (under the ruler Birkiyarouq), Kingdom of Khurasan and beyond the River (under the ruler Singer), Kingdom of Aleppo (under the ruler Radwan), Kingdom of Damascus (under the ruler Daqaq) and the Roman Saljuks Sultanate (under the ruler Qalj Arsalan). Most of the regions in Palestine were subjected to the Damascus regime, and during the weakness of the two rulers of Syria (Radwan and Daqaq), a lot of private rulers emerged, none of which dominated more than one city. The Crusaders commenced their military campaign of 1098 CE (491 H) while Muslim regions in Syria, Iraq and others were torn apart because of their differences and bloody conflicts. The two brothers, Radwan and Daqaq, sons of Titish, launched a war against each other in 490 H. Many battles broke out between Mohammed Ibn Malikshah Birkiyarouq because of their conflict over the power in which they exchanged victories and sermons in the Caliphate court during the period 492-497 H.

Chapter Reviewing the Facts

Of course, It Isn't always pleasant to hear active comments about what we are doing. Sometimes our feelings get hurt, our ego Is wounded, or the feedback strikes us as, well, stupid. That said; let's consider a shift In our perspective. Feedback Is a form of coaching. When we work with a coach, he or she Is constantly giving us negative feedback-?and we appreciate It. A golf coach, for example, will correct the way you hold or swing the club and you're delighted to get the negative feedback. In fact, you pay for all these â€Å"complaints. † Dissatisfaction happens.What we choose to do about it can make all the difference in reading customer and employee loyalty. To do something about dissatisfaction, we need to know when it is happening-?we need to get the silently dissatisfied customer to speak up by creating open communication channels. (Customer Service: Career Success through customer Loyalty) Chapter 9-Reviewing the Facts 2. – What are the three important steps ne eded to recover the potentially lost customer? The first step consists of both apology and accountability. Say, â€Å"I'm sorry,† and take ownership of a mistake, even if it's because of supplier or other problems.Next, work with the customer to determine an appropriate remedy. This involves the customer in the resolution and sometimes uncovers less costly solutions. Resolution should not only address a customer's direct loss but also compensate â€Å"pain and suffering. † Some refer to such compensation as â€Å"atonement. † Manage expectations with resolution schedules. In one Citibank experiment, specifying time frames for next steps increased customer satisfaction by 40%. Finally, follow-up. Determine whether the customer has received the promised treatment, and, more important, how they feel about it.One study indicated that a follow-up call to a once-unhappy customer can boost satisfaction by 5%-7%, and intentions to repurchase by 8%-12%. The second level is building integrated customer recovery capabilities In the following four areas: Companies must do more to upgrade the skills, training and pay of customer service representatives, especially since they handle an estimated 65% of all complaints. Other employees must also understand the Importance of customer retention. Ford trains new hires In such recovery skills as Interpersonal communications.Others regularly rotate employees Into customer service to underscore the Impact of departmental processes on customers. How much authority do employees have to recover customers? Employees at Marriott International, for example, can spend up to $2,500 without authorization to compensate customers. What are the timetables for resolution? Brothels Airways research showed that of customers defected if it took the company longer than five days to respond want level AT complaints trigger corrective Acton? Can any employee handle recovery, or should you depend on special representatives trained for customer recovery?Customers should be easily able to complain via email, letter or even well-publicized hot lines. Systems should streamline complaint acceptance, and generate complaint-based reports. Insurance giant USA scans every complaint letter into its database. Causes for the complaint are analyzed, and processes examined to avoid similar complaints in the future. To institutionalize improvements, systems should be developed to hold other departments accountable for their actions. Complaint data should also be used to determine investment priorities and service improvements. (Small Business Resources – How to Recover Lost Customers)

Hcs451 Quality Management Assessment Summary Essay

HCS451 Quality Management Assessment Summary Quality Management The Duke University Medical Center (2005) website defines â€Å"quality improvement as a formal approach to the analysis of performance and systematic efforts for improvement†. Quality improvement programs are found in a variety of industries and are constructed differently. The medical field tends to use quality management to focus on patient and staff safety, reducing medical errors, and avoiding or decreasing morbidity and mortality rates. Health care organizations have been attempting to improve the quality of care for as long as â€Å"the nineteenth-century when obstetrician, Ignaz Semmelweis introduced hand washing to medical care, and Florence Nightingale who determined†¦show more content†¦The third long-term goal of a health care organization like a hospital is remain compliant and achieve and maintain accreditation. This can be achieved through other long and short-term goals. If the short-term goals of self-assessments, education, and im plementation of quality improvement processes are put into place, the organization can be successful with their quality management program. Upper-level management will need to address this success and work to ensure that the policies and procedures put into place are maintained. Internal and External Factors that Influence Quality Outcomes Various internal and external factors influence quality management and outcomes in hospital organizations. One internal factor that affects quality management and outcomes is leadership within the organization. Leadership is important to have successful quality management outcomes because if the leadership does not support it, no change within the organization will be successful. â€Å"This commitment must be shared by the board of trustees and all senior clinical and administrative managers and understood that it is a long-term process† (Chassen and Leob, 2011). Leadership is one of the most influential internal parts of the quality management program. Leadership can either help the organization succeed with their support or help the organization fail if they do not support and follow
