As the weather cools, the grubs move more deeply into the soil to overwinter (survive the winter). Grubs hatch from the eggs and feed on grass roots. The adults begin emerging from the soil in mid-May and are present through August. It can be distinguished from similar beetles by the tufts of white hair visible at the end of its abdomen. An adult Japanese beetle is about ½ inch long and has a metallic green body and legs with coppery-brown wing covers. Japanese beetles ( Popillia japonica) feed during the day and are perhaps the most readily recognized beetle pests that feed on roses. Since many beetles feed mainly at night, the gardener rarely sees them, only the damage that they cause. Many of these beetles feed mainly on flower buds or open blossoms but can feed on leaves. Japanese beetles ( Popillia japonica) with characteristic damage of leaf skeletonization.ĭavid Cappaert, Michigan State University, A number of different beetle species feed on roses. See Table 1 for products containing these insecticides. Soil drenches or granular applications of systemic insecticides, such as imidacloprid or dinotefuran, will control aphids and last longer within the plant to prevent future infestations. Sprays containing bifenthrin, cyfluthrin, horticultural oil, lambda cyhalothrin, malathion, neem oil, permethrin, or pyrethrin will control aphids. If contact insecticides are deemed necessary, the following are available in homeowner size packaging. In addition, these insecticides kill the natural enemies of rose aphids. Leaving even one aphid alive can result in a large population very quickly. However, it is important to note that aphids are very difficult to control because they multiply rapidly. Higher toxicity insecticides are available. Repeat the insecticidal soap spray three times at 5 to 7-day intervals. Insecticidal soap must be sprayed onto the aphids to be effective. Roses can also be sprayed with insecticidal soap to control aphids. Spraying with water should be repeated as frequently as needed, focusing in particular on new growth. If ants are present, they should be controlled.Īphids can be hosed off with a strong stream of water directed above and below the leaves. Ants are sometimes associated with aphid infestations, and they will protect the aphids from their natural enemies. Their natural enemies tend to keep aphid populations under control except in cool weather. The honeydew supports the growth of unsightly, dark-colored sooty mold fungi on the leaves.Ĭontrol: Aphids have several natural enemies, including parasitic wasps, ladybird beetles (ladybugs) and larvae, and green lacewing adults and larvae. As they feed, aphids excrete honeydew, a sugary substance that attracts ants and wasps. Heavy infestations can reduce the number and quality of blooms. Their feeding results in distorted growth. A low population of aphids does little damage to a rose bush however, aphids reproduce rapidly and can quickly reach numbers that cause damage. They are soft-bodied, pear-shaped, pink or green insects found in clusters on new growth of buds, leaves, and stems.Īphids feed on plant sap with their piercing-sucking mouthparts. Rose aphids are small (about ⅛ inch long). Gideon, Various species of aphids feed on roses, but the predominant species is the rose aphid ( Macrosiphum rosae). Rose aphid ( Macrosiphum rosae) infestation on leaves of hybrid tea rose.Īnne W. Apply all pesticides according to label instructions, and follow all precautions. Always be sure to read the pesticide label before purchasing. When applying a pesticide, thorough spray coverage of the plant is important. If chemical control is necessary, use the least toxic chemical, plus be sure to apply it at the most susceptible stage of the insect pest. Whenever possible, initially try physical control measures. Often, more than one control option is available for a pest. For the best control methods, it is first necessary to identify the pest correctly. These inspections increase the likelihood that a pest infestation will be detected early, when pest numbers are low and control is easiest. When trying to control insects and related pests on roses, the plants must be thoroughly inspected regularly. For information on diseases of roses, see HGIC 2106, Rose Diseases. For more information on the cultural requirements of roses, see HGIC 1172, Growing Roses and HGIC 1173, Pruning Roses. A vigorously growing rose is much more likely to survive pest damage than a stressed plant. As with any plant, the priority should be to provide the rose with the cultural conditions required for best health. Unfortunately, the numerous insects and related pests that attack them can make growing them “interesting”, if not outright challenging. With their showy and often fragrant blooms, roses are easily one of the most popular flowering plants grown in South Carolina.

The city houses important financial institutions and the corporate headquarters of numerous Indian companies and multinational corporations. It is also one of the world's top ten centres of commerce in terms of global financial flow, generating 6.16% of India's GDP, and accounting for 25% of industrial output, 70% of maritime trade in India ( Mumbai Port Trust, Dharamtar Port and JNPT), and 70% of capital transactions to India's economy. Mumbai is the financial, commercial, and the entertainment capital of India. In 1960, following the Samyukta Maharashtra Movement, a new state of Maharashtra was created with Mumbai as the capital. Upon India's independence in 1947 the city was incorporated into Bombay State. During the early 20th century it became a strong base for the Indian independence movement. Mumbai in the 19th century was characterized by economic and educational development. Along with construction of major roads and railways, the reclamation project, completed in 1845, transformed Mumbai into a major seaport on the Arabian Sea. Beginning in 1782, Mumbai was reshaped by the Hornby Vellard project, which undertook reclamation of the area between the seven islands from the sea. For centuries, the seven islands of Bombay were under the control of successive indigenous rulers before being ceded to the Portuguese Empire, and subsequently to the East India Company in 1661, through the dowry of Catherine Braganza when she was married off to Charles II of England. The seven islands that constitute Mumbai were earlier home to communities of Marathi language-speaking Koli people. In 2008, Mumbai was named an alpha world city. Mumbai lies on the Konkan coast on the west coast of India and has a deep natural harbour. Mumbai is the centre of the Mumbai Metropolitan Region, the sixth most populous metropolitan area in the world with a population of over 23 million (2.3 crore) living within the Mumbai Metropolitan Region. Mumbai is the de facto financial centre and the most populous city of India with an estimated city proper population of 12.5 million (1.25 crore). Mumbai ( / m ʊ m ˈ b aɪ/ ⓘ, Marathi:, IAST: Muṃbaī also known as Bombay - the official name until 1995) is the capital city of the Indian state of Maharashtra.

The person that came with me did not get one of those aftercare sheets either. I have recordings of our conversation inside the shop and not once was I rude, I simply explained my unhappiness and that I would like my money back since the stencil I picked out did not match the tattoo I was given. The way she handled the situation had a negative impact on my business because I had no way to defend myself against the false accusations she made about this situation, We could have addressed the issue if we were given the chance, but instead we were harassed and badgered on social media and in person.Ĭomplaint: I am rejecting this response because:Yes, I signed a waver but the "attached" aftercare paperwork was not give to anyone. called the authorities out of concern for my well-being, by what her comment meant and her continued harassment. "she was going to take it to another level", but would not explain what she went meant by the comment. She continued to curse and threaten us by stating. The following day I called her because I did not feel comfortable with her in my business due to the way she was acting. She said she would be back the next day but did not show up. She showed up at the tattoo shop while I was out due to complications with my pregnancy. I responded to one of her post and asked her why she did not let us know she was not happy and if she did not like our designs then why would she pick one, She had no response but to further insult and curse at me. Even after multiple posts and badgering us, she still never personally contacted us. She started to insult the look of our shop and the designs we offer. She did not just put up a review, she posted paragraphs that included cursing and insults, She continucd to post negative comments that did not even make sense to her complaint to purposely hurt my business. For example, she did not tell us there was a problem before she left the shop, nor did she call, email or message us in anyway, She never gave us the chance to address the issue. If she was not happy with how it turned out she had multiple options how to let us know so we could have handled the situation. All customers must sign consent forms before the procedure and aftercare is offered, She chose a design and at the end of the session,was asked if she wanted anything added and if she was happy with the outcome. Butterfly tattoos are the most removed tattoo in America today!

Both of the triangles are parallel and congruent to each other. It's a three-sided prism where the base and top are equal triangles and the remaining 3 sides are rectangles. Recall that a prism is a solid which has identical polygon ends (bases), flat parallelogram sides, and has the same cross-section all along its length.Ī prism having three faces as rectangles and two triangles as its bases (one triangle acts as the top) is called a triangular prism. Let us start with the pre-required knowledge to understand the topic base area of a triangular prism. The base area of a triangular prism is the area of the triangle of the prism. In this section, we will discuss the base area of a triangular prism along with solved examples. Hence, the volume of the doll house is 12000 cu.cm. The volume of the model doll house will be the sum of volume of the 2 prisms, that is, The volume of the rectangular prism part is 6000 cu.cm. Volume of a Rectangular Prism = l x b x h The volume of the triangular prism part of the doll house is 6000 cu.cm. The volume of a Triangular Prism = \((\frac\) ) 40 x 10 x 30 Because the cross-section of a triangular prism is a triangle, the volume of a triangular prism can be calculated using the following formula: The table below shows the volume of triangular and rectangular prisms.Ī prism with three rectangular faces and two triangular bases is known as a triangular prism. Similarly for a rectangular prism the base area will be obtained by using the area of the rectangle formula. For a triangular prism the base area will be obtained by using the area of a triangle formula. The volume of a prism is the product of its base area and length. Tank/aquarium size: Small loaches under 6 inches should be in a tank no less than 40 gallons. How to Take Care of Loaches Habitat, Tank Conditions & Setup Below is a summary of the main loaches found in pet stores. If you decide to keep a large variety of loach, you should keep them in an extremely large tank of over 300 gallons. This is because loaches are not usually kept in large enough tanks in captivity. Although 16 inches is usually a maximum for large captive loach varieties. Some loaches can grow up to 1 inch if they are the smaller varieties, whereas others can grow to a maximum of 20 inches. They have an eel-like body which makes them stand out more than other aquarium fish. The superfamily name Cobitidae is derived from the term Aristotle which refers to small fish that bury under the substrate. Since they are bottom dwellers, they rely on these barbels to locate food that is hidden in the substrate. Alongside their barbs, they also have barbels at the base of their head. This is an exceptional amount for a captive fish. Surprisingly, there are over 1200 species in the Cobitoidea family. They will have barbs below their mouth that they use for defense purposes. Image Credit: Joan Carles Jaurez, Shutterstock They will burrow under the substrate to both hides and to find food. An interesting behavior that loaches seem to do is dig. These fish are exceptionally curious and appreciate crevices and caves in their tank. They will be hiding and seeking shelter under plants, in caves, or under pieces of wood. You may find them very inactive during the day. You can purchase several loaches for a tank, but you will not see the group or form shoals. They are not schooling fish but do appreciate some of their companions. These fish are most active at night and will display a foraging behavior when food is introduced into the tank. Online suppliers generally sell quality loaches at $5 to $8. The shipping may be too much for them to handle and they will arrive at you in poor condition. The same problem arises if you choose to purchase online from a breeder. When their immune system is low from stress, they will develop a multitude of illnesses before you even get to enjoy your new fish friend. It is best to avoid wild-caught loaches, because of their high stress with transportation. The price can vary depending on the type of loach you choose to buy as well as the size, color, and rarity of the fish. You can expect to pay between $3 to $5 for one loach at a pet store. Image Credit: Nantawat, Shutterstock How Much Do Loaches Cost? A well-cared-for loach can live longer than a loach kept in poor conditions under constant stress. Loaches have a lifespan ranging from 10 to 12 years. Loaches can easily be confused with Pangio cuneovirgata, Pangio myseri or even Pangio semicincta. This can be done by asking for the scientific name of the loach. Since there are so many different types of loach, you should double-check with the supplier if the species you are buying is the correct one for your needs. There are over 1,000 different species in the aquarium trade, with many available for life in captivity. When combined with their susceptibility to illness and their sensitivity to medications, it is a difficult task to successfully treat them. They lack scales on their head which makes them sensitive to most medications. This is because some can get quite large, with the flower loach reaching a whopping 20 inches! They are prone to a variety of diseases that do not usually affect other fish in the same situation. They are omnivores who will scavenge along the floor of the aquarium in search of food.ĭespite their small size, they require a large tank. We recommended loaches to be cared for by an intermediate or advanced aquarist who has an established tank. They are not good beginner fish because of the experience and knowledge level required to keep them healthy. They are shy and peaceful (except for the semi-aggressive clown loach). This is when they will be most energetic and scavenge for food around the tank. These fish are nocturnal and will be most active at night when the tank lights have been switched off. Loaches are peaceful, bottom-dwelling fish that help keep your aquarium clean. Look for a category under which it would make sense.ġ0. The leader should describe the process and announce the time for this step:ħ. We’ll all need to work hard and quickly to make that happen. This meeting should take not more than 3 (usually 2) hours. It gets distracting and makes the process take longer. Plan subsequent design meetings as needed.Determine priorities (e.g., by taking votes).Sort each of those categories into subcategories.The leader should announce what the different steps of the process are and how long the workshop will take: At the Start of the Meeting: Announce the Steps and Timing Guidelines Put some pens or markers and blank pads of sticky notes on a table. Add a “?” category name for notes that are not understandable.ĥ. Stick these category names high on a blank part of a wall, so many notes can fit below.Ĥ. For webpages, some common categories are: Search, Global navigation, Homepage, Legibility, Footer, Page layout. Consider creating a few category names to help get the sorting started. The color coding makes it easy to tell from which test each finding originated.)ģ. (This picture shows notes from testing sessions each note color corresponds to a different test participant. Just before the meeting begins, enlist some help and put all notes on the wall, in no order.Īll the sticky notes are posted on a wall in an affinity-diagramming workshop.Alternatively, tape flip-chart paper on the walls and stick the notes on top, or use easels if walls are not tape-friendly. Choose a room that has walls on which sticky notes can be attached (e.g., glass or whiteboard).Steps for Affinity Diagramming in UX Before the Affinity-Diagramming Workshop Facilitate moving past any issues that may arise, such as helping the person who seems lost, or pairing people when one is idle and another is very busy.Track and communicate time for each step.Describe what people should be doing at each phase of the workshop.So, it’s important to have a leader to keep the meeting moving quickly and productively. It can be tiring to interpret and sort many notes, and attendees can lose interest if the meeting drags on. prioritizing each note, and determining the next steps in design or further research. After the test or the ideation session, the team has a workshop devoted to analyzing the notes by: During an ideation workshop, attendees or the workshop facilitator write each idea on a sticky note.ī.During a usability session, the facilitator and the observers write observations, findings, or ideas - each on one sticky note.In this step, team members write down ideas or facts on separate sticky notes. ideas that surface in design-ideation meetingsĪffinity diagramming in UX usually involves two steps:Ī.observations or ideas from a research study.While affinity diagramming as a method can be used by individuals as well as groups, in UX, it is used primarily by teams for quickly organizing: In it, users sort index cards with category names and commands written on them.) (However, in UX, ‘card sorting’ stands for a very specific research method for determining the IA of a site or application. Often used in UX, affinity diagramming is adapted from the KJ diagramming method (named after author Kawakita Jiro).ĭefinition: Affinity diagramming refers to organizing related facts into distinct clusters.Īffinity diagramming is also known as affinity mapping, collaborative sorting, snowballing, or even card sorting. One method that helps teams collaboratively analyze research findings as well as ideas from ideation sessions is affinity diagramming. However, in such UX workshops, it can be challenging to engage the team, and create order among diverse ideas and facts. Have you ever involved stakeholders in design critiques, ideation sessions, or meetings devoted to analyzing research findings only to find them uninterested? And were the ideas and research findings ever ignored or forgotten? UX workshops have numerous benefits: educate people and make them empathic towards users, make stakeholders feel involved and responsible for ideas and research findings, create awareness of usability issues and design challenges, build common ground across all parties involved, and bring together many types of backgrounds and expertise. Liquefaction occurs up to a certain depth of the soil and hence if we are able to pre-determine the potential and the possible depth of liquefaction, building foundations can be designed to go below the liquefiable depth and can remain unaffected in earthquake shaking. This can result in major damage during earthquakes. Liquefaction takes place when loosely packed, saturated sediments at or near the ground surface lose their strength in response to strong ground shaking, and flow like a thick fluid. Learning about potential tsunami hazard is essential in coastal areas with high or medium earthquake risk. Historical records may also contain accounts of secondary hazard events triggered by past earthquakes. Maps may exist that describe the extent of tsunami inundation, liquefaction, or land-sliding. Obtain information on these hazards from the government agency responsible for emergency management. Engineers need this additional information to design the facility properly.Įarthquakes can cause secondary hazards that include fires, landslides, liquefaction (see definition below), floods (can be triggered by failing dams and embankments, glacial lake outbursts, or by landslide-blocked rivers) and tsunami in coastal areas. For critical facilities such as major dams, power plants, or major hospitals, a more detailed analysis should be done to determine the expected level of earthquake shaking at that particular site. Hazard maps in the building codes provide sufficient information to properly design ordinary buildings and other typical structures. The building code or regulations for earthquake resistant design typically contain these maps, or they may be available from the government agency responsible for earth science or emergency management. Most countries that fall within earthquake hazard zones have maps that show how strong scientists expect earthquake shaking to be throughout the country. Scientists who study earthquakes use other tools: they investigate faults where earthquakes occur, measure the slow movement of tectonic plates, and search for geologic traces left by ancient earthquakes. In many areas, centuries may pass between major earthquakes, meaning that instrumental records provide an incomplete picture of the hazard. Recording of earthquakes using scientific instruments began only around 1900. Areas with infrequent, large earthquakes are sometimes classified as having medium seismic hazard.Ĭommunity memory and historical accounts of earthquakes can provide useful information to supplement scientific studies. But such earthquakes have happened in the past, and understanding the earthquake history of a place is important before determining a location for a project and initiating the design of the structures. It may seem unlikely that a large earthquake would take place hundreds of kilometers away from a tectonic plate boundary in areas with low levels of strain on the crust from tectonic motion. In many countries, earthquake history can be obtained from written historical records.

Further detailed information should be obtained to adequately account for the level of hazard. Project planning decisions, project design, and construction methods should take into account the level of earthquake hazard. Based on this information, the impact of earthquake should be considered in all phases of the project, in particular during design and construction. This means that there is a 10% chance of potentially-damaging earthquake shaking in your project area in the next 50 years. In the area you have selected (Victoria) earthquake hazard is classified as medium according to the information that is currently available. |
