Iranian architecture displays a class and elegance that cannot be matched with any other style of architecture and design. It is quite distinct from that of Muslim countries. The major features of Iranian architecture are: structural ingenuity basically in vault and dome construction; a skill of decoration with freedom and intricacy incomparable to any other form of architecture.

The pre-Islamic buildings include the remarkable Elamite ziggurat at Chogha Zanbil. Baked brick was used for outer surfaces by the 12th century BC. Most of the greatest buildings were built with a religious purpose, and even in secular buildings religious influences are entirely absent. Palaces were present, and their shapes, sizes and colors varied according to the ruling dynasty.

The first great development of ancient Persian architecture took place under the Achaemenid dynasty during the Persian Empire, from about 550 to 330 BC. There are numerous remains of Achaemenian period, including two palaces, a sacred precinct, a citadel, a tower, and the tomb of Cyrus.

Royal architecture under the Achaemenid also included tombs cut in solid rock, of which the best-known examples are those at Naqshah Rostam near Persepolis. Little is known of the popular building practices of the period, but archaeologists believe that the ordinary dwelling was made of mud brick. After the conquest of Persia by Alexander the Great, Greek influence, in its late, Hellenistic phase, was predominant in the arts of Persia. Examples include fragments of bronze sculpture found at Shami, and the Parthian sculptural reliefs at Behistun.

During the Islamic period “mosques” became the major buildings in Iranian architecture. Outstanding examples of early Islamic Iranian architecture include the Mosque of Baghdad built in 764, the Great Mosque at Samarra erected in 847, and the early 10th-century mosque at Nayin.

After the 17th century, Iranian artists copied European paintings and engravings, and the native traditions declined. But Iranian architecture still managed to leave a huge impact on the world.

The job market is riddled with great competition, and so you need to set yourself apart early. Unfortunately, the only weapons at your service are a piece of paper and some information. How you present that information is going to determine if you get that awaited for interview. Try making use of some of these great tips to write impressive resume cover letters. For the purpose of this article, we will use a generic job of “Office Furniture Purchaser” to illustrate the main ideas.

* Don’t use up your first paragraph with a boring introduction. Grab their attention first. Give them the reasons you are qualified right off the bat. E.g.: Thank you for allowing me the opportunity to apply for your advertised position as office furniture. am keen to talk about the high points of my career from the past 15 years in the office furniture industry with you.

* Don’t use old stand-bys like “Attached please find my resume…” Your prospective employer can SEE your resume; they don’t need you to tell them it is there. Avoid statements that waste space. If you need to refer to your resume in your cover letter, use statements like this: E.g.: My CV will clearly illustrate I am a qualified and skilled office furniture purchaser with a proven track record in budget saving techniques. There, you just told them that you have experience, and you know how to save them money, AND you have a resume.

* Use simple, uncomplicated language in your cover letter. If you are educated, they will know that you can use big words in the interview. E.g.: I would love to work with your team, and establish my record breaking office furniture purchasing experience with your company.

* Make sure you mention your job requirements, and mention words used in the ad in your resume as things you can do. It may look blatant, but it does have a positive effect on the mind of the prospective employer. For example, if the ad says, “seeking detail oriented and efficient time manager for Senior Office Furniture Buyer”, you want to say… E.g.: My skills include a flawless attention to detail, commitment to meeting deadlines, and multi-tasking experience as a Senior Officer in a National Furniture Division.

By following these simple suggestions, you will have a resume that will make a good impact. Good luck!

In feng shui, dragon is the powerful symbol that gives strong yang energy. It is known as a symbol of prosperity and success. Placing the statue, sculpture or figurine of a dragon (or dragons) in the right direction and place can help to give the best result. Since the dragon is associated with the east therefore according to feng shui placing this mythical animal in the eastern areas of your house will be especially beneficial. This placement will help the family members to become prosperous and successful and bring in other positive effects. Placing the dragon in your bedroom or any room where you are seeking relaxation is not recommended as the dragon is a very active symbol.

Like the dragon, phoenix is also exist only in legends and fairy tales. The Chinese call phoenix the King of all birds. It is also sometimes known as the August Rooster and associated with the tenth Chinese zodiac sign, the Rooster. It is a Chinese symbol of grace, luck and happiness. Feng huang (Chinese word for phoenix) is the guardian of the south, therefore the feng shui masters will suggest that the pictures and statues of phoenix is best when placed in the South areas of your house.

In feng shui the dragon is paired with the phoenix to symbolizes perfect balance of yin and yang. In this case, the dragon is the yang and phoenix is the yin. But if the phoenix is displayed alone without the dragon, then the bird will give the yang energy instead of yin. When these two popular mythical animals are put together they will not only strengthen relationships but also bring back the warmth of togetherness in relationship with the useful energy of the phoenix. The dragon-phoenix combination is one of the most common symbol you can find in the Chinese wedding ceremonies and dresses.

The very first step to become an iPhone application developer you buy or have a Mac as without it it will not be easy to code apps for iPhone. It is not necessary you only own the top model, but you can buy anyone in your range. Any Mac which is capable of affording maneuverability for developer will suit. If yours is the tight budget, buying Mac Minis is good choice. It is portable and can be taken anywhere. The next step is to own the SDK (software development kit) for coding iOS apps. Apple provides SDK that developers can use in the iPhone app development process. The SDK includes stuffs like Xcode and simulator that are required in testing of tapp. Other things include performance analyzers, template interface builders and reference library. There are also plenty of documentations with the SDK. Third thing you will need to become an iPhone developer is you learn Objective C. As an extension of C with OOP principles, Objective C is the primary programming language to code apps for iPhone and other iOS devices. If you already have some programming experience, learning Objective C is going to be quite easy. Note – The official Apple Software Development Kit offers complete details and documentations on anything related to iPhone app development.

After that comes the starting out with development. It is the fourth step. Make the project plan and start coding the application with using objective C. If you are already a Java programmer, you can adjust and practice your programming skills to get the project done. You can also easily make several types of modification if you have already concluded a project. The SDK has a number of sample projects which can be used in the development of iPhone apps. You can start with these sample projects and just reveres engineer them to make your own apps. Also new features and functions can also be added to create new apps.

The fifth step is to become a real developer by signing up to iPhone Developer site at $99. With signing up to this, you agree all the terms and conditions of Apple for iPhone application development. It depends on the time you have to contribute to your project or the type of application you want to build but, an iPhone application development project aimed at game may take about two months to get done.

Once you complete the project, it’s time to submit it to iTunes and wait for approval. Apple general takes 1-2 weeks in approving application for iPhone and other iOS powered devices.

Today computer is considered to be the most competent product as selling point of view, dictionary or Wikipedia for the students, sort of entertainment for leisure time etc. In short, its platform for every sort of things to be search and to be performed upon and that’s why it has entered to every facet of human lives. From kids to teenager and from grown-ups to older people, everyone feels the need of computer in their day to day life. But the age group which makes maximum of computer is kids to adult i.e. between age group of 9-28 years. Kids are using for gaming and entertainment purpose and for education purpose while adults use it for professional or career point of view. In short, computers and laptops have not remained luxury anymore rather it has become necessity of the life.

=> Hence parents are also looking forward to install a computer in their houses as they wants that their coming generation should not be left behind. And that is why kids are accessed to computers and laptops at very early age.Even in schools and colleges, student who is having extra ordinary knowledge of computers and its operation is proved to competent enough then other students. And that is the reason why parents are having so much eagerness for installing computer at home. Not every parent can afford such expensive computers and laptops and hence they are having option of buying used or second hand computers and laptops. The market outflow of used computers, Discount PC or refurbished computers and laptops is tremendous.

=> As soon as you decide to buy discounted PC or used computer you just need to browse down few websites and you will come across hundreds of computers and laptop which are already used or which are refurbished by dealers and retailers. Some of the B2B and B2C websites will provide you with incredible deals over the Used Computers and used LCD. Such cheap computer proves to be effective and comes with guarantee even. You just need to make sure which are the ones who provides efficient after sales service.

=> But remember buying out refurbished computers and refurbished laptops is not at all an easy task. One has to clarify and analyze every detail regarding computers and laptops. Some of the feature which needs to be always taken under consideration is size, colour, configuration warranty period and brand.

Uzumati Hughes is USA Author. He is Working in supplier and several services. He has applied his knowledge and understanding to a wide variety of Refurbished Laptops and Refurbished Computers.

Sustainability means managing the resources well without damaging the environment now or in the future. In other words sustainability also refers to ensure that our decisions today may not harm the future opportunities for future generations. Now, have you ever thought that what a sustainable architect does in terms of product, process or buildingdesign?Sustainable architecture is a term that describes environmental friendly design methods in the field of architecture.

A client can believe on sustainability but the proof and evidence can help the client to better understand the concept of sustainability. Architect Brighton offers sustainable modern architecture, design and master planning service in order to meet the needs of their clients. Their goal is to create -green’ architecture which is magnificent in terms of design, keeping in mind the sustainable lifestyle and culture. Sustainable architect is not an individualist approach rather it’s a holistic approach. These architectsare more concerned about the reuseand recycling of the natural resources that are input to a building. A well designed building will have number of issues like water and energy utilization, proper use of materials and much more. Architects can deal with the ecological aspects of constructing these buildings. These aspects are designed to increase the efficiency without being detracting from the function of the building.

Sustainable architect focuses on designing a unique set of strategies to construct or develop a building intelligently. The architects minimize the use of nonrenewable resources in the development and function of buildings. These architects must consider the material flow in the building ecosystem. Few of these have been mentioned below:

Building materials and used materials Energy usage and combustion by products Water usage and Graywater sewage Consumer goods and recyclable materials Solar radiation and wasted heat Wind and polluted air Rain and groundwater

Before constructing a building, Architect Brighton keeps in mind three important strategies i.e. energy conservation, water conservation and material conservation. Apart from this, an architect should put certain efforts to reduce the impact of a building on its local environment (e.g., current terrain, plants, wildlife).In order to attain sustainability, Sustainable architect must be well educated and professionally trained about the various environmental issues. They must be well aware of the methods and techniques of developing a sustainable design building with economical use of natural resources. If the growth would concentrate on creating the best with what already prevails, re-using or adjusting current components and communities, certainly the outcomes would be remarkable.

As we know rendering technology of render farm used in deferent entertainment areas such as movie, animation, games etc. Rendering technology also used in building architecture industry. Rendering technology used in architecture industry known as 3d architecture rendering. Render farms are able to provide 3d software to complete a big architecture project easily and perfectly. By using rendering technology private owners can get a design to prepare the dream home at small charge. It is possible to watch real life look of the future building in the design created by a render farm, which is also called cloud render farm using 3d rendering technology.3d rendering technology help architects to build architectural models with perfect scales and dimensions. Rendering technology also used by architects or property owners to decide colors and materials perfect for their architecture. Most of the architects use cad software for 3d architecture rendering. Architects can also use 3ds Max, Revit, Archi CAD software for 3d architecture rendering. Architecture rendering provide designers and architects a clear concept about their task. They can avoid any kind of unwanted interruption and save a lot of time during architecture process. 3d architecture rendering is very popular in architecture industry for its various advantages such as this technology can produce a great efficiency during architecture development, little deference between design and bodily realization, designers or architects can visualize the development earlier to its architecture and it also increase trust in their design.3d architecture rendering have some sorts in architecture industry like 3d interior rendering, 3d exterior rendering, 3d product rendering etc. to complete a big architecture project rendering technology is the first thing essential for a property owner because it produce trust in a design through virtual visualization to modify before the architecture begins in the real world. So after all we can say that 3d architecture rendering is very essential innovation for architecture industry to build up architecture precisely with strong architectural design.

Many people think that the only way to find property development projects is to connect with a real estate agent. This is far from true. The fact is that it is possible to locate many different potential properties by using the internet. Here is why.

You are not limited by geography
If you are looking for property development projects in another city you will be able to find them much more easily using the internet. There are often photographs and pieces of information available that can tell a potential investor a lot about a property. Because you can do it remotely it is often possible to create a list of potential properties you will want to see in person and will be able to hit the ground running. Making the most of any house- or property-hunting trip can really save valuable time and money.

You can access information about the market in general as well as specific properties. It may be difficult to get information on market conditions during a short visit to a location. But, if you are able to put together information on the market and any comparables before you arrive you may end up being in a stronger position as a buyer than if you are coming into an area with no advance information.

You are not restricted to real estate agents alone
By looking online you may be able to get information on short sales, foreclosures and properties that are being sold by their owners rather than by real estate agents. Having the widest selection of properties to choose from can really help you find the property development project that meets your needs and budget best.

You are not necessarily restricted to one agent
If you speak to a real estate agent about a potential property development opportunity you may find that said agent believes you have entered into a contract with them. If you end up dealing with another agent this can cause legal issues and added stress as well. By researching potential properties online you can decide which agents you want to work with either because they are offering the properties that you are most interested in or you like the way they market properties and represent their clients.

There are drawbacks to looking for property development projects online. Unless you are working with an agent who has judgment that you trust you may not feel comfortable taking their advice about a potential property.

By learning how to research and locate property development opportunities online you may find that you will be able to break into the development market as quickly and easily as possible. In todays real estate market you never know when a deal is going to become available and it is definitely worth keeping your eyes open to sudden development opportunities.

Many lucky homeowners are using equity they gained during the recent bull market in real estate to purchase second homes. Leveraging one property in order to acquire another can be a solid investment strategy, as you increase your investment portfolio one step at a time, and one house at a time, by using each new asset to help pay for another one.

Banks will normally scrutinize credit reports and income documentation more stringently when you borrow to buy a second home, because they want to make sure that both of your mortgage obligations can be paid each month without a problem. And they may require larger down payments and charge slightly higher loan fees or interest rates than they did when you bought your first home. Nevertheless, many homeowners find it easy to qualify for new loans, and this is especially true for those who maintain excellent credit ratings. With the potential to profit from your purchase through equity appreciation, the repayment of a second mortgage is often easier than it was for a first mortgage.

For those who plan to use the second home as an income-producing property, there are also available tax deductions. As a landlord, you can usually deduct such things as repairs, utilities, and even routine trips you take to visit your property and check on its upkeep. Many investors combine their use of the second home, so that it is rented or leased sometimes, and at other times it is used as a personal vacation home. When you arent making money by leasing it to others, you save money by not having to pay for hotel lodging at vacation time. A qualified tax planner can help you find all of the various tax advantages to spending your vacations in your own second home.

When applying to secure a loan for an income producing second home, it is a good idea to present your lender with a thorough business plan and any documentation that illustrates the practical income potential of the property. If the previous owner made a profit each year by renting it out as a holiday retreat in the summertime, your lender will be more inclined to have confidence in your own ability to manage the property for extra income. One good way to show income potential is to hire a professional appraiser, who can do a market analysis of your property by comparing it to similar income-producing properties in the same area.

Another popular way to finance a second home purchase is by using an equity line of credit based on the value of ones first home. Banks typically charge more interest for these loans, but you are able to avoid many of the closing costs that are associated with originating a separate mortgage. And regardless of whether you apply for a mortgage or an equity loan, you may be eligible for tax deductions of interest payments and other related expenses.

There is an amazing assortment for you to select from: there are round, square and hexagonal shapes and every single colour or style that you can think of from vibrant greens, darkish sophisticated Chinese red, deep midnight blue, ones decorated with a blue and white Chinese dragon motif, zebra pattern and even ultra contemporary silver finished ceramic garden stool types as nicely as numerous other attractive shades and patterns.
A great area to get started if you are preparing to obtain a ceramic garden stool is on the world-wide-web, because thirty minutes invested in the convenience of your house admiring the numerous sorts of ceramic garden stool, will give you a considerably much better notion of the kind of shade and pattern that would best fit in with your house dcor. I constantly say that if you do your window browsing at household on the pc, you can save by yourself several hours of dragging about from keep to store and ending up also tired to care what you get.
You only have to kind in the words ceramic backyard stool into the search engine and you would be surprised at how several retailers there are on-line offering some beautiful ceramic, porcelain and pottery backyard furniture and cute decorations like garden gnomes, frogs and other animal types. Terracotta pottery plant pots stuffed with pink and white petunias or salmon pink bizzy lizzy make like an desirable border dividing your patio ‘outdoor room’ from the rest of the garden.
When I’ve been out in the backyard carrying out a bit of weeding or dead-heading the flowers, I like to take a break by bringing out a cup of coffee and a plate of cookies, which I area on my ceramic garden stool. Then I settle down comfortably in my chair beside it and get pleasure from the come to feel of the sun on my skin. I’m usually amazed by the numerous uses that ceramics can be place to and I guess it’s the durability and attractive surface of porcelain and ceramic that has created ceramic floor tiles and wall tiles like an enduring component of everybody’s dream house, within and out.
I’ve usually like the sensation of warmth and sunny skies that I get on a patio with a terracotta colored ceramic ground tile. I don’t forget going to Spain 1 summer season and the decorative ceramic tiles that you see everywhere in the bars and in people’s residences had the most amazing geometric patterns on them. Especially in the components of Spain that had been occupied by the Moors hundreds of years back. The Moors were last but not least expelled but the ceramics that they left behind them have remained common and they seriously are so very. I don’t bear in mind seeing any types of ceramic garden stool there, but it’s a style that’s certainly undertaking effectively in the U.S.

Journaling is an excellent tool for dealing emotionally with almost any issue in life. The therapeutic applications of journal writing are endless. But it’s also true that sometimes you feel stuck, unable to make a move in any direction, and not even able to sit down comfortably with your notebook.

For any number of reasons, known and/or unknown, you feel empty. You want to get answers, but you’re paralyzed in some limbo of inaction. You’re uninspired, listless, drifting. You haven’t even cleaned your house for the past month.

Hold it right there. When in doubt, simplify. Could it be that modifying your environment will energize you?

As sentient beings, people are affected by their environments. The flow of energy and the balance of forces in a given environment are studied in the ancient Chinese art of feng shui. Feng shui observes that clutter brings low, confusing, and draining energy into your home, which is detrimental to your own energy and well-being.

Clearing out physical clutter can seem like an overwhelming and tedious process, but when you live and work in a clear, open space, your mind also becomes free and uncluttered.

Your ease and wellbeing have everything to do with your surroundings. Could it be that your ennui is a result of the mess around you?

Here are some ideas to make the task of de-cluttering more palatable.

1. In the room or space where you plan to do your journaling, set a timer for 15 minutes.

2. Turn on some favorite music, open windows if the weather allows, invite a loved one to join in if you wish.

3. Clean one area of the space for the 15 minutes. Throw out as much as possible.

4. Be merciless. If you can’t think of a reason to keep it in a few seconds, get rid of it! Hoarding is a generally unhealthy thing to do.

5. Stop when the timer buzzes. Take a step back and admire your work. Great job!

If you want to, set the timer for another 15 or 30 minutes, and continue. Or just do 15 a day for a while. At some point, the room will be clean and refreshed. Now open your journal and write about the experience.

What did you see and feel when you looked at this room before? What do you see and feel now?

What old baggage, physical or emotional, were you able to throw away while cleaning? What items were the hardest to get rid of? Why?

How do you plan to keep your writing space fresh, inviting, and clean in the future?

Lounge room, also called sitting room, is aroomin aresidentialhousefor relaxing and socializing.

Home treadmills are complex machines made from computerized and mechanical parts. If your home treadmill. has problems, you’ll be able to repair a number of issues at home. A treadmill has numerous components; remember you may want to use different tools to fix the device. Following some basic guidelines and steps to find out which is wrong with your treadmill will help you repair it at home.

Unscrew and open the engine cover by using a screwdriver. The engine cover is located in the top, usually on one of the sides of the treadmill.

Investigate the motor. Make certain all the pulleys move smoothly by moving them with your hands. If there are dust particles around the motor, gently clean off the motor with a dry cloth.

Look at the belt that is round the motor. The belt is the main part that helps the treadmill mat move properly. Determine if it is worn out, searching for nicks, cuts or fraying. Replace the belt if it is worn badly.

Spray a water-displacing spray lubricant, such as WD-40, over gears and pulleys associated with the motor if you hear a lot of friction noise received from it.

Get rid of the front part of the treadmill to expose the treadmill mat. With the engine cover open, you are able to remove the front cover to reveal the treadmill mat wrapped around a central pulley.

Check out mat through the entire machine. Lift the mat to see the underside. You may want to switch the mat if any markings, burns or rips are present.

Put front cover back on and so the motor cover.

Unscrew the top computer panel. Look inside to check that all wiring across the within the panel is properly strung and in good condition. If so, replace the panel; if not, get one of these professional repair services. want to buy home treadmills check the best home treadmills.

Traditional clock generators use a simple integer-N phased-locked loop (PLL)-based architecture. The output clock frequency is a function of the input clock frequency and the PLL divider values as shown in the equation
Equation: fOUT = fIN.N/P.R
Traditional single PLL-based IC solutions are suitable for simple integer clock multiplication of reference inputs or clock generation from crystal inputs. However, many applications require clock generation of multiple non-integer-related frequencies (e.g., 125 MHz Ethernet and 106.25llMHz Fibre Channel). Traditional solutions require that the crystal frequency be changed to support each unique frequency plan. This forces the designer to use one or more custom crystals and multiple clock generator ICs to generate the required set of frequencies, increasing the cost, complexity and power consumption of the overall solution.

New Any-Rate Clock Multiplier Architecture Simplifies Design
Recent advances in mixed-signal analog design have made it possible to provide any-rate frequency synthesis from a single device. Silicon Labs newest clock architecture leverages a fractional-N PLL used in concert with a low-jitter fractional divider termed MultiSynth to produce any-rate frequency synthesis on multiple output clocks. The flagship of this new product family is the Si5338 Any-Rate, Any-Output Quad Clock Generator. This technology dramatically simplifies timing architectures by integrating the frequency synthesis capability of four PLLs in a single device, greatly reducing size and power requirements compared to traditional solutions.

MultiSynth Technology
The Si5338s low phase noise, high-frequency VCO supplies a high-frequency output clock to the MultiSynth block on each of the four independent output paths. The first stage of the MultiSynth architecture is a fractional-N divider, which switches seamlessly between the two closest integer divider values to produce the exact output clock frequency with 0 ppm error. To eliminate phase error generated by this process, the MultiSynth calculates the relative phase difference between the clock produced by the fractional-N divider and the desired output clock and dynamically adjusts the phase to match the ideal clock waveform. This novel approach makes it possible to generate any output clock frequency without sacrificing jitter performance. Based on this architecture, each output clock can be individually programmed to generate any frequency from 0.16 to 350 MHz, and select frequencies to 700 MHz. Typical jitter performance enabled by this MultiSynth-based architecture is 1 ps RMS.
