Side Effects of Oral Cancer Treatment

Side effects are the undesirable effects in body due to usage of drugs or medical surgeries. Side effects are common in oral cancer treatment as the healthy tissue or cells also affected. Side effects are vary from person to person and type of treatment  given.

Side effects of surgery
Side effects of oral cancer surgery varies depends on the site of surgery. The side effects are
  • Pain at the site of surgery due to removal of tissue
  • Swelling of face
  • If surgery is on tongue or jaw leads to difficulty in eating and talking
  • Infection at the site of surgery
  • Bleeding from the site of surgery.
Side effects of radiation therapy
Side effects of radiation therapy on oral cavity depends on the amount of radiation given. The more exposure to the radiation, the more will be the side effects.
  • Dry mouth is common in radiation therapy. It is due to the permanent damage of salivary glands. Lack of saliva production leads to dental infections like dental decay.
  • Sore mouth is painful ulcers on mouth after radiation therapy. Using local anesthetic mouth rinses helps to numb the area or pain killers relieve from pain.
  • Gum bleeding can be controlled by maintaining oral hygiene. Avoid tooth picks to control it.
  • Delays healing time as radiation therapy makes the tissue hard to heal.
  • Restricted jaw movement happens in radiation therapy. It affects the jaw muscle and makes it difficult to open mouth. This can be treated by doing jaw exercises and speech therapy.
  • Damage of thyroid and pituitary gland: During radiation therapy, damage of thyroid and pituitary takes place. Lack of thyroid and pituitary hormones leads to gain in weight and tiredness. This can be corrected by medicines.
  • Redness of skin at the site of radiation can be treated by maintaining hygiene.
  • Tiredness after radiation therapy is seen in many patients.
  • Loss of taste sense after radiation therapy on head and neck cancer. A metallic taste in mouth is common and causes lack of apatite.
  • Loss of smell sense is due to the radiation on oral cavity, which affects nose. Dryness of nose leads to decrease in the smell sense.
  • Voice changes varies depending on the site of area gets affected by radiation. It is temporary and you can regain your voice  after a few days.
Side effects of chemotherapy
Side effects of chemotherapy are same as the radiation therapy like infection, dryness of mouth and bleeding gums. Side effects of chemotherapy depends on the amount of dose taken. Other side effects include:
  • Blood cells: Chemotherapy affects bone marrow and decreases the production of blood cells. Due to lack of enough blood cells, poor oxygen supply leads to infections
  • Hair loss: Chemotherapy affects hair to become thin. Hair on scalp and eye brows and eye lashes fall down. But this can regain once the treatment is completed.
  • Skin: Chemotherapy also affects the skin. The skin becomes dry and sensitive to sun. Rashes and irritation of skin
  • Nails: Nails become dry and brittle.
  • Digestive system: Chemotherapy affects digestive system and leads to side effects of nausea, vomiting. Some tablets irritates bowl.
  • Nerve damage: Chemotherapy damages nerves on hands and legs. This leads to numbness or sharp pain in hand and legs.
  • Kidney, liver and lungs: Some chemotherapy drugs alters the functioning of these organs.

During this procedure, if the dentist detects any tartar or scrap left on your teeth, they will peroform conventional scaling and root planing methods to remove that scrap but it takes more time for the dentist, and it is also done by hand. Today, the dentist's job has become easier with this ultra sonic dental cleaning technique.

Process of cleaning using ultrasonic scaler
Ultra sonic dental cleaning uses an instrument called ultrasonic scaler. During the treatment this ultra sonic scaler make some vibration and sound wave that crushes and removes the deposited calculus on your teeth and also it crates some shock waves that take away bacterial cells. It also washes and flushes the pockets and exposed root surface by sending the cool water. This water also reduces the heat caused by the vibrations. With this technique the teeth will be more clean and have fresh gums.

Difference between ultrasonic cleaning technique and conventional method
  • Ultrasonic cleaning are more effective in cleaning corner of teeth than the traditional method.
  • Ultrasonic sclaer can penetrate deeper in to periodontal pockets than manual instruments.
  • Ultrasonic scaler takes  less time than using manual instruments.
  • Conventional hand-held scaler creates discomfort but this is not the case with ultrasonic cleaning.
  • Conventional scalers are easy to use by any dentist but ultrasonic scalers must be performed under the supervision of the dentist who are specialized using this ultrasonic scalers.
  • Ultrasonic scaler produces sound waves rather the conventional method this may be option for all patients with pacemakers.
  • The scaling done with ultrasonic is painless and comfortable.
  • Ultrasonic technique is effective in detecting the early stages of gum and periodontal diseases, and it removes all calculus at once and saves time compared to traditional method.

Types of Fuel Pumps

A fuel pump is an  essential component of internal combustion engines. These are used to pump  fuel from the fuel tank to the injection system. Fuel pumps are aimed to pump fuel from the tank  to the engine and delivered at  low pressure to the carburetor or at high pressure to the fuel ignition system.

Gasolene engines use low pressure mechanical pumps. These are mounted outside the tank. On the other hand, compression ignition (diesel) engines use electric fuel pumps fixed inside the tank. Some diesel engines have two fuel pumps one for low pressure supply in the tank and one for high pressure pump near to the engine.

Types of fuel pumps include mechanical fuel pumps, electrical fuel pump and turbo fuel pump. We'll discuss each of them briefly.

Mechanical fuel pump
A mechanical fuel pump is a device that delivers fuel to the engine. Mechanical fuel pumps are mostly used in spark ignition (petrol) engines. These are located between the fuel tank and the engine.

How a mechanical fuel pump worksThe mechanical fuel pump is driven by a camshaft. It's connected to crank shaft. As the shaft rotates the camshaft, it passes over the pivot lever and forces it to lift at one end. The lever fulcrum point is very close to the part that actuates the diaphragm, so very little movement of the arm at the camshaft results in significant movement of the diaphragm.

As the diaphragm is pushed up, the fuel is pressurized and moves out of the pump into the fuel line. From there it enters the carburetor. The lever arm allows the diaphragm to return to its original  position. The one-way valves in the pump prevent the return of fuel from the carburetor and a path is opened for fuel to be drawn from the fuel tank. Vacuum is created by the diaphragm which causes fuel getting sucked  into the chamber from the fuel tank.

Electrical  fuel pump
The electric fuel pump is a commonly used one. It's located inside the fuel tank. The electric fuel pump pumps fuel from fuel tank to the fuel injection system at a higher pressure its mechanical counterpart does. Because of this reason electrical pumps are placed replacing mechanical pumps. The electric fuel pump works with the fuel injector in cars.

Working of electrical fuel pump
As the pump is located in the interior of the tank, it is protected from heat as gas and diesel are cold in liquid state. 

The electromagnetic switch called solenoid is used to pull the diaphragm. The solenoid consists of iron rod that pulls the diaphragm downwards and fuel is drawn into the ignition chamber. The rod that pulls the diaphragm returns to it position.

When you turn the key on the pump gets an electric signal, which leads creating pressure on fuel in the tank. When the engine is just to start, the pump sends fuel at pressure down the line for ignition.

Turbo fuel pump
 Turbo pumps are not very popular because they are used mainly in jet and rocket engines.
They are centrifugal pumps and get their propulsion from a gas turbine.

Working of a turbo pump
In a turbo molecular pump, the gas molecules move in bulk and interact more with each other than with the walls of the container.

Turbo pumps do not work in this case because the momentum imparted the by rotors is insignificant compared to intermolecular interactions. This is known as molecular flow. Now the turbo pump can impart momentum on each molecule individually.

The rotor blades rotates around 90,000 rpm. When they hit the gas molecules in the engine, they impart momentum. The angles of the rotor and stator blades drive the gas molecules towards the exhaust.
The fuel pump is an important part in your car's engine system and therefore it's worth to know about it.

Vitamins for Healthy Teeth

Vitamins are essential for the growth maintenance of the  body. Certain amount of vitamins are required by the body to promote your oral health. Oral health plays an important role in the overall health. If you have a deficiency of some vitamins, you get easily prone to tooth decay and infections, thus your oral health can be badly affected.

Vitamins help in promoting healthy gums and teeth. The vitamins that will be best for your teeth can be found in food that you consume. Pay attention on your daily diet and see that, are getting the vitamins as per the body requirement. This article discusses importance of vitamins for healthy teeth.

Vitamins for healthy teeth
Vitamins mentioned here are the ones essential for healthy mouth:
1) Vitamin A for promoting healthy gums : If you are a vitamin A deficient, your gums get easily affected. Vitamin A maintains the mucous membranes and tissue around gums. Vitamin A also helps in healing process of gum tissues that are swollen. Milk, cheese, eggs, liver and beef are rich in vitamin A, and therefore are good for your teeth.

2) Vitamin B for keeping your teeth strong: Deficiency of vitamin B can make your teeth weak. It also causes burning sensation on your tongue thus making swallowing difficult. Foods that is known to have high amount of vitamin B are meat, fish and mushroom.

3) Vitamin C helps in boosting immunity: If you have a deficiency of vitamin c, it can cause bleeding in gums and loose teeth which can even lead to tooth loss. Vitamin C help in boosting immunity and prevent infections that can damage your oral health. There are certain citrus fruits and drinks that are rich in vitamin C. But make sure that you rinse your mouth thoroughly after consuming such fruits as they contain acid which can dissolve enamel of your teeth. Other food that are rich in vitamin c are kiwis, strawberries, sprouts etc.

4) Vitamin D for oral health: Vitamin D helps in absorbing calcium that is required for healthy teeth. Calcium is required for your teeth and jaw bones and in order to maintain oral health.
Deficiency of this vitamin can lead to a condition called burning mouth syndrome. Symptoms of this include burning sensation in mouth, dry mouth and metallic taste. Dry mouth can further lead to tooth decay due to inadequate levels of saliva in the mouth. Saliva helps in neutralizing acids in the mouth.

The vitamins that can be best for your teeth can be found naturally instead of using special supplements.

Three Major Categories of Computer Software

A software is a computer program or a set of instructions that are designed to perform various actions within less time and with less human efforts. They process the information stored on the computer and generate output. Software needs to be stored or installed on the computer to work.

There are different types of software that are designed to perform various operations. But, software are broadly classified into three major categories. They are system software, application software and programming software. In this article, we discuss them briefly along with a few examples.

System software
System software is often called as low-level programs as its interaction with the user is at very basic level. The basic function of the system software is to start up the computer device. System software also makes hardware of the computer device to start and operate. It enables applications installed on the system to activate and work according to users' instructions. In simple, it acts as a bridge between the hardware and application software.

Examples of system software are operating systems, compilers and loaders.

Application software
It is also called as application packages. Application software is also a computer program or a set of instructions that process the information and delivers the output that end user requires. There are hundreds and thousands of application software because there are hundreds and thousands of jobs that user wants to perform on the computer. Application software can be a simple game or a complex program that performs business operations.

Applications software can be customized. Developers are available in the market who can develop an application software according to your requirements and specifications. It does not require specific skill to work on an application, but an understanding of how an application can work.

Examples of application software are word processors, electronic spreadsheets, database management software, business applications, games, etc.

Programming software
Programming software is also called as software development tool or programming language. Programming software have predefined syntax and keywords that are used to design, develop and maintain applications of a computer. Programming software is a set of instructions or group of software programs.

Programming software is used to develop an application, rectify mistakes if any in the application, test whether the software is processing the information, generate the required output, maintain the developed program in the future with modifications and adding updates to the program.

An ordinary user needs training to understand and develop an application using programming language.

Examples of programming software are C programming language, Java programming language, etc.

These are the three major categories of computer software that are helpful for your business in many ways.

Three Major Components of Enterprise Computing

Enterprise computing is a complete package of information technology for an enterprise or an organization. It is capable of doing all the information technology (IT) related operations of the organization. Enterprise computing on a whole contains three major components. They are enterprise software, enterprise database and enterprise networking. We will discuss them briefly in this article.

Enterprise software

Enterprise software is the most important component of all three because it is one that performs major functions crucial to the operations of the business. There are many subsystems within enterprise software. The four major subsystems of enterprise software are:
  • Enterprise resource planning (ERP) – It is a combination of various software modules. ERP coordinates among all parts of enterprise software, and helps organization in performing operations quickly and efficiently.
  • Supply chain management (SCM) – SCM is responsible for producing, storing and supplying the products. It keeps track of inventory and flow of products from organization to customers.
  • Customer relationship management (CRM) – CRM describes business and customer relationship. It helps businesses get new customers and retains old customers.
  • Business intelligence (BI) – It is a method of organizing raw data to meaningful form and studying the past and present, and predicting future of the business.
Enterprise database
  • Organization may contain huge amount of data including sharable data, confidential data, resources and business logic.
  • Enterprise data is divided into internal (used within organization) and external (used outside the business also) categories of data based on organizational requirements.
  • Enterprise database is critical part of an enterprise. Therefore, it should be maintained well.
  • Enterprise data should have following characteristics:
    • Scalable – Enterprise data must be flexible and scalable to facilitate frequent changes and requirements that occur in an organization.
    • Secured – As enterprise data include critical information, they should be managed through authorized and controlled access.
    • Quality – Enterprise data has to follow organizational standards. Enterprise data should be free from error, and there should not be duplication of data.
    • Integrated – Enterprise data must be same and consistent across users and systems who use it.
Enterprise network
  • Enterprise networking is the backbone of an organization. It connects all the computers and other devices irrespective of their environment across the organization and outside the organization (if required).
  • Enterprise network may consists of computers with different operating systems, other electronic devices like printers, scanners, mainframe systems, smartphones, tablets, etc.
  • It enables communication among devices, and makes it easier for them to share information, resources and retrieve required information that is on the server or on other enterprise computer.
  • Enterprise network increases the performance of the business by enabling communication among all the systems and provides security to them.
  • It also eliminates the unwanted, inactive or isolated users in the network.
  • Enterprise network sometimes may be a group of LANs (local area networks) or WANs (Wide area networks) depending on the requirements of an organization.
These are the three important components of the enterprise computing. They should be maintained well for proper functioning and growth of the business/enterprise.

What is Business Software?

It is a software program that helps businesses/companies of all sizes to measure, increase their productivity, reduce the cost and to facilitate the organizations operations. It can be easily installed in PCs and laptops based on the requirement of a business.

Business software programs are mostly used by IT companies to make their work more efficient and to optimize their processes in both internally and externally.

This is basically split into two categories one is business or system software that supports the daily activities of the company and the other one is application software that supports the managerial decision making process.

Here are some most important types of business software, ie: BIS – Business Intelligence Software, CRM - Customer Relationship Management Software, ERP – Enterprise Resource Planning Software, and KMS – Knowledge Management Software, PLC – Product Life Cycle Management, BPS – Business Process Management, etc.

So, whether you have a small, mid-sized or large business, you need to install the software according to your business needs, so that your office will run smoothly and it will also become more productive, which can increase your profit margin. Business Software is used to increase revenue and to reduce costs. So to reduce the cost and increase the productivity of your business you need to install some form of Business Software based on your company needs.

What is an Application Software?

Application software, also referred as app or application, is the name given to the group of programs that perform specific tasks for users. It is a computer software designed to carryout specific tasks by the users.

These programs are classified into two groups: system software and application software. System software is a set of low-level programs that most deal with computers at a basic level for interacting, whereas application software exists on above the system software and includes  instant messengers, word processors, database programs, spreadsheets, games, anti-virus programs etc. Sometimes application software exists along with system software.

Application software is based on customer requirements. Examples of this are: Quicken and Quick books for financial applications and Word, Excel, Power-point for office applications, graphics software and media players. However, many application programs deal principally with documents. Software’s such as video drivers, browsers, games are not considered as applications.

Application software is successive with system software and middle-ware, that come through computer's capabilities, but that indirectly benefit the user. Here the function of system software is to serve the user via the application.

Application software uses different computing platform to serve various purposes. For some software applications, versions are available to install in various different platforms; others have smaller requirements. Example, for Windows – geography application, for education - Android application or Linux gaming. Sometimes a new application arises which runs only in one operating system or platform. This is called a killer application.
