Things to Consider When Choosing a Web Hosting Company

There are many web hosting services to choose from for your business website. If you are new to business and trying to approach the web hosting company for getting the hosting service? Then, you should take care of the following points before you choose a hosting company for your site. The things that you should take care are:

Type of site
Generally, people will have websites and blogs and whether it is a blog or website you need have online presence and visibility. This will help you go for hosting.

How much you can afford for hosting?
Once you found that you need a separate hosting service, the next question that should come to your mind is how much you can afford for hosting depending on the size of the site and the over all requirements of your site. If you are able to figure out this, you can choose the hosting technology based on the cost and requirements of your website.

Which hosting service level you need?
Once you have fixed the requirements of your site along with the price that you can afford, you can move on for choosing the service level. In general there are three major kinds of hosting services that people get through a hosting company. They are shared hosting, VPS hosting and dedicated hosting. Apart from these three, one more is free.

Check which level of hosting service your site needs that based on the requirements of the site whether it is small, big, etc. and how much you can afford. When it comes to free you don’t have to pay so, you don’t have to think about the price but, you should think about the requirements.

Which hosting technology your website needs?
Along with the level of service, you should also check which technology your site needs – Linux or Windows. Some sites need Linux and some need Windows. You should check the benefits that your site gets and compare them and choose the one most suitable for your site.

Along with the above points, location of the service is important as well. So, before you opt for a hosting service, check whether your site is targeting local business or international business. If it is local, it’s sensible to go for local hosting as it bring multiple advantages: local IP, better loading time, good customer support, etc.

Usability and limitations of a CNAME record

Cname, a short abbreviated form for canonical name, is a record in DNS database which indicates the domain name and its aliases that it is associatedwebsite monitor with, such as IP addresses, sub domains etc. We all know that every website requires an IP address and sometimes we need more than one domain to point to the same IP address. This is where Cname comes in handy, in which a record is being created in the DNS database for each alias. There can be any number of Cname aliases associated with the host name of a computer, but there should be a specific Cname record for each alias. This means if we change the IP address of this specific record within the network, then all the Cname records pointing to it will automatically follow the new IP.
How Cname record exactly works?
When people try to access websites they may not type the domain name exactly the way it is, and sometime get it wrong by mistake. For instance if is the website, then people may try it as or or even etc. The most popular way to resolve this issue is to create a cname record with different names pointing it to the same domain, so that even if the user gets the name wrong, it would still redirect the access to the original domain by referring the Cname record. Similarly, if you want to point all your sub-domains or any particular domain to your main domain, all you need to do is create a Cname record and redirect it to the original domain.
What are the possible restrictions while creating cname records?
There are some limitations that partly restrict the creation and usability of a canonical name record. Some of them are:

  • Cname record must always be pointed to the domain name, but not to an IP address. While activating the record, there should be no other DNS entry for that domain name, otherwise the server gets confused in interpreting the actual name and its alias.
  • Multiple resource records with the same Cname is technically not allowed. When alias is created as Cname record, they should never map to other resource records with the same name even in other file types like NS and MX, which means there should not be duplicate entries even in other file monitoring
  • To combat the technical difficulties, sometimes people keep multiple web servers and try to automate the process by pointing the host name to the standby server in case if the first one goes down. For this they create a Cname chain or loop instead of doing it manually. There is nothing wrong in pointing one Cname record to another, however it is not considered as good practice because multiple look-ups use more resources and it may impose an over load on the servers.

Different Kinds of Fans used

industrial centrifugal fansIn boiler two kinds of drafts are predominant – forced draft and induced draft. Each requires set of fans that can perform its function. Draft fans are classified as centrifugal and axial type based on the direction of the air flow in the boiler. Different industries use different type of fans depending upon their industrial needs.

Centrifugal Fans

In this type of fans air flow is along the radial direction of the fan. Centrifugal fans use a rotating impeller to move air initially, radially outwards and then tangentially away from the tip of the blades. They can generate high pressures. They are used in dirt removal of the air streams, in material handling applications and systems operating at high temperatures.

Working of the Centrifugal Fans

  • Initially the incoming air moves parallel to the hub and turns radially outwards the perimeter of impeller and blade tips.
  • The air gains kinetic energy while moving from impeller hub to the blade tips. Then the kinetic energy is converted to pressure energy as air enters the tangential discharge path.

Types of Centrifugal Fans

    • Backward-inclined curved blade
      In this type the blades are inclined away from the direction of rotation. They     are more efficient than the flat blades. Low angel of contact with the airstream promotes the accumulation of deposits on the fan blades. Suitable for forced draft system. This kind is often selected because of its non-overloading motor characteristic.
  • Backward-inclined, airfoil blade
    The airfoil blades tilt away from the direction of rotation of the fan. They are     most efficient but most unstable because of the stall. Performance drops off at high airflow rates. Suitable for forced draft system.
  • Radial Blade
    This type of fans are capable of handling high-particulate air streams, including dust, wood, chips and metal pieces because its flat blade shape limits the material build up. When the system is at halt where vibrations are produced, the blades allow this fan to operate safely and quietly.


Axial Fans

In axial fans the air flow direction is parallel to the impeller shaft. The parts of the axial fan are propeller and vanes. Axial fans usually have a series of vanes coupled on the propeller shaft.

Types of Axial Fans

  • Propeller Fans
    They develop high airflow rates and low pressures. They are not suitable for the extensive duct work. They have less efficiency and are inexpensive. Often used in ventilation systems.
  • Tube axial Fans
    They achieve higher efficiency than propeller fans. They are used in medium pressure systems. It has high operating speeds and generates moderate airflow noise. As these fans have rotation mass, they attain high speed in less time.Centrifugal Fan
  • Vane axial Fans
    It is similar to the tube axial fan with outlet vanes to straighten the air flow. The air flow profile is similar. These type of fans are used in induced draft type system.

Advantages of Axial Fans

  • The kind of blades in axial fans are small and have light weight and low cost.
  • Used in synchronous speed of the induction motor.
  • Belt drive units offer wide range of speed selection.

Disadvantages of Axial Fans

  • Access of motor is difficult due to location of blade
  • When compared the airflow axial fan must rotate at higher speed than the centrifugal fan.

There are some other kinds of fan designs too that can be used in draft of the system. Some are given as centrifugal inline fans, centrifugal roof exhaust fans, utility fans etc.

All about Dental X-rays

Dental X-rays help dentists to visualize teeth diseases and the surrounding tissue that usually cannot be seen with simple oral examination. Additionally, X-rays also help dentist to find and treat problems early in their development, which can save money, unnecessary discomfort and sometimes even life.

What are the problems that dental X-rays can detect?

In adults,

  • Dental X-rays can be used to show areas of decay that may not be visible with oral examination, especially the areas of teeth decay.
  • They help to identify decay occurring beneath an existing filling.
  • It helps to reveal changes in the root canal or the bone that result from infection.
  • Also, reveals the bone loss that accompanies gum disease.
  • An abscess (infection at the tooth root or between the tooth and the gum) can be identified with dental X-rays.
  • Other developmental abnormalities such as tumors and cysts can be identified.

In children,

  • Dental X-rays are used to look for decay.
  • They help to determine if there is sufficient space in the mouth for the incoming teeth to fit well.
  • They are used to check for the development of wisdom teeth and identify if the teeth are impacted.
  • Also, they help to determine if the primary teeth are being lost quickly to allow permanent teeth to come in properly.

How frequently the teeth be X-rayed?
The frequency of getting X-rays often depends on your dental and medical history and current condition. Some people need X-rays as often as six months and others with no recent gum or dental disease.

People who fall into high risk category who may need X-rays taken more often include:

  • Adults with extensive restorative work, such as fillings to watch for decay beneath the existing fillings.
  • Children need more X-rays than adults because their jaws and teeth are smaller and still developing. As a result, decay can reach the inner layers of the dentin or tooth, quicker and spreads faster.
  • People who intake lot of sugary beverages to identify tooth decay.
  • People with periodontal gum disease to look for bone loss.
  • Smokers to monitor bone loss that results from periodontal disease.
  • People who have dry mouth or disease states. Dry mouth conditions usually lead to development of cavities.

Are dental X-rays safe?
Radiation exposures such as sun, minerals in the soil and dental X-rays can damage the body’s cells and tissues and lead to cancer in some cases. Fortunately, the radiation dose you are exposed during the dental X-rays is small especially in case of digital X-rays. Recent advances in dentistry have lead to various measures that helps to minimize the risks associated with X-rays. Those who are really concerned about radiation exposure during X-rays can discuss this matter with their dentists regarding guidelines and other alternatives.

How to Select an Industrial Fan

A desired Industrial fan is selected in order to have a better environment in the working area. If we install a smaller fan in a larger area it will not FD Fanprovide the required amount of air or gas to the system for its functioning. Similarly, if we have a larger fan for a smaller working area or smaller functioning, it will result in wastage of energy and causes extra money to the organization.

Selection of an Industrial Fan depends on the following factors

  • Total cooling requirements
    • Cooling requirement mainly depends on
      • Heat which must be transferred
      • Amount of air flow.
    • An efficient system provides the required operating conditions that increase performance and life of all components in the system.
    • In case of ventilation system where cooling is given utmost importance, selecting a correct type of fan is very important. Similarly, in case of cold storage systems cooling requirement is important.
  • Flow rate
    • In industrial terms flow rate is called as CFM (Cubic Feet per Minute). The CFM is the unit of flow rate of air or gas.
    • A required capacity of an industrial fan is to be selected based on the amount of fluid to be transmitted.
    • For a low pressure industrial work, axial fans are selected and similarly for high pressure industrial applications a centrifugal fan is selected.
    • If, in an application the distance of travel of fluid is more, a fan with more motor capacity is selected in order to give high velocity for the fluid.
  • Static pressure
    • The resistance to airflow caused by moving air through a pipe, duct, hose, and hood slots is called static pressure in a fan.
    • Static pressure is expressed in terms of mm or cm. Static pressure is considered as the other physical properties such as volume (flow rate in this case) and temperature vary with the variation in the static pressure.
    • By using the static pressure, we can find the rate of fluid to be delivered by a fan to the amount of cooling required in the system.
    • By using static pressure, performance tables are developed which play an important role in the selection of an industrial fan.
  • Air temperature altitude correctionCentrifugal Fan
    • These are the tables developed on the temperature of the working area plotted against altitudes.
    • For example, if we know the static pressure of the system, air flow rate and the level of elevation, a desired working temperature of the
      system can be found out from this data and the required is selected with air temperature altitude correction tables.

Selection of a fan is very important to maintain required performance and cut down the excess cost to the organization. It is simply easy to select a fan
if the capacity and application are known.

Maintenance of Industrial Fans

tunnel ventilationIndustrial Fan contains various rotating and sliding parts which are to be maintained regularly for longer life. Regular maintenance also prevents unexpected accidents happening in the system. Some basic maintenance steps of the industrial fan are as follows.

Maintenance Steps

  • Bearing lubrication
    • If bearings are not properly lubricated, it will produce noise and fail easily with high rate of material wear. Lubrication should be done as per the instructions of the manufacturer.
    • In case of oil lubricated bearings check the quality of oil and if necessary replace it with another one. In the case of grease lubrication, over lubrication will cause overheating.
    • Bearings should be protected from contamination.
  • Belt inspection
    • In case of belt driven fans, wear rate of the belt is high and they lose tension reducing their transmission efficiency. As the time continues the wear increases and produces noise which is due to energy loss of belts.
    • Belt inspection is important in case of large fans because of the amount of power loss. For example, in a 400 HP fan 10% loss in power results in 40HP power loss, which intern results in further decrease in power if not inspected regularly.
  • Motor repair or replacement
    • Motor is the important part of a fan which gives the necessary rotating power to the blades. Regularly maintained motor too have a finite life because overtime usage of the motor results in the breakdown of winding insulation.
    • Motors suffer insulation break down if winding temperature exceeds rated value for a longer period of time.
    • When it comes to either replace or repair of the motor, many factors are to be considered such as size, type, period of operation, electricity consumption etc.
  • Fan cleaning
    • The level of performance decreases due to the contaminant deposits on the fan. If contaminant deposit is not uniform, it results in unbalance problems and drive train wear. Contaminant deposit is mainly seen in the ventilation systems.
    • Fans that operate in heavy loads or high moisture air streams, should be regularly cleaned.
    • Fans like, backward inclined airfoil are highly susceptible to contaminant deposit. These deposits disturb the airflow rate, increase the operating costs and decrease the efficiency.
    • In material handling or in moisture content applications radial blade, radial tip blade and forward curved blade types are mostly used Centrifugal Fanbecause of their resistance towards deposits of contaminants.
  • Leakage
    • Leakage degrades system efficiency and performance. Leaks are developed in flexible connections and in places where the vibration levels are high.
    • Leakage results in poor delivery of air or gases to the destination points. This intern results in the overall decrease in efficiency of the system.
    • Leakages points such as improper fittings, cracks in duct work and other flexible joints can be easily identified by inspecting visually.

Maintenance of a mechanical system result in increasing the life of an entire system, prevent any extra investment to the organization and provide safety to the work force in the work environment.

Manufacturing Processes Involved in Fan Blade

ID Fan manufacturersBlades of a fan perform the major action and hence they must be manufactured with utmost precise. The manufacturing process involves various steps such as casting, welding, hardening etc.

Resin infusion technology

The main principle of infusion is to suck a resin into reinforced fibers using vacuum. The vacuum decreases the pressure at one end of the fabric, allowing atmospheric pressure to force resin through fibers. The distance and speed by which we can infuse a fabric will be dependent on

  • Resin viscosity
    • Low viscosity allows the resin to travel more distance in the resin stack at given pressure gradient and it will create less drag in the induced stacks. This reduces the number of injection points needed on a large component and increases ease of infusion process.
  • Permeability
    • The permeability of a fabric is dependent on three factors, such as fiber diameter, fiber sizing and fabric type.
    • The permeability is the ease of flow of a metallic or plastic material when it is in liquid form.
  • Pressure gradient
    • The pressure required to infuse resin stack is dependent on the atmospheric pressure and the performance of the vacuum pump.
    • As the resin infuses into the fabric stack, the drag on the resin front begins to increase. The amount of drag is directly proportional to the volume of infused fabric stack and its permeability. So, when a given quantity of fabric stack is infused, the drag will be equal to the original pressure gradient, and the infusion will halt.
  • jet fans

  • Infusion process
    • The infusion carried by several steps which are to be performed by different equipments in the system. The parts are
      • Resin feed station
      • Sectional vacuum line
      • Resin feed line
      • Resin flow front
      • Vacuum pots to collect resin
  • Process
    • When the vacuum bag is fully pressurized and bridges are closed, the component is ready to be infused. If the resin is mixed manually, this is now coupled with a short rest time to allow the majority of air added at mixing to arrive at surface.
    • The speed of the resin is controlled by valves on the inlet pipes. The speed of the resin is high at the beginning of infusion and this leads to extra lag on infusion creating dry spots which can exhaust the resin supply before batches are mixed.
    • When process is running in controlled manner, more resin is mixed before opening the next set of valves. The set of valves open when the entire resin front has passed the feed line at bottom and top of laminated stack. This causes increase in speed of resin flow and increases pressure gradient by removing quantity of fabric in drag. The process is repeated until the entire component is infused with resin.
    • This process has potential unpredictability for every component mainly in resin flow and susceptibility of system to failure generally caused by vacuum integrity.

Fan blades must be of precise design. So they must be manufactured with special process in order to have better efficiency.

Few Facts about Dentist Drill & It’s Uses

Today, people are suffering with various dental problems caused due to lack of hygienic dental habits. Build up of food particles inside the gaps of teeth lead to tooth cavity and its decay. Failing to clean the food particles leads to development of bacteria on teeth and it becomes tough to clean with brush. Hence one of the alternative methods to clean teeth can be done by using dental drill.

Dental drill is a tool used by dentists to clean and remove plaque from tooth’s surface and to bore through tooth enamel. Modern dental drill has made dentists to work more accurately and quickly than ever before with less pain.

Parts of a dental drill

  • Turbine type: Rotary system in an air powered powered drill contains an impeller/ rotor mounted on a spindle that rotates at high speed to catch air from the compressor
  • Hand piece: The gears, motor and drive shaft are positioned inside the hand piece made of either titanium or plastic.
  • Drive shaft: Several gears are attached to the drive shaft and these toothed wheels transfers the rotary motion along the length of the drill.


  • Drill bit: These drill bits should be hard enough to wear away the tooth enamel and hence made up of hardest materials like tungsten carbide and some are even tipped with diamond.

Working of dental drills:

  • Modern dental drills are powered by air driven or electric motors. The other components of today’s dental drill are gear, hand piece, tungsten drill bit.
  • A series of drive shafts and gears are present inside the drills hand piece that transfer rotary motion from power supply to the tungsten drill bit placed in the head piece.
  • Drills that are motorized electrically can rotate about 30,000 rpm. For a drill that is turbine powered, a compressor helps to convert pressurized air in to mechanical energy thus rotating the tungsten drill bit at over 300,000 rpm.


  • New technologies which include air abrasion drills and laser improves the experience of dentist by providing drills fr removing decay without generation of noise, heat and other vibrations.

Uses of dental drill

  • To prevent various dental diseases dentists use dental drills for treating the damaged tooth enamel.
  • It is used to clean up the food materials inside the teeth cavities.
  • Dental drills are helpful for people suffering from pain due to dental problems.
