Nanotechnology Microchip for Detecting Type 1 Diabetes

Filed under: 2014 — Tags: , , , — Ralph C Dreher @ 7:52 AM

Technology is being used in every profession including medical science. Recently, a microchip was created using the nanotechnology to detect Type 1 diabetes in patients. This is a big benefit for doctors because for detecting Type 1 diabetes doctors need to spend a lot of time as they go to identify the specific protein markers in blood. This may take days to weeks. But the recent research by Stanford university school of medicine came up with this nanotechnology chip. This chip can detect Type 1 diabetes within a very low time span – in minutes.

Type 1 diabetes
Type 1 diabetes is an immune disease, by which the immune system can affect the pancreas. By this the pancreas stops producing insulin – a hormone to process sugars. Early detection of Type 1 diabetes may benefit the patient.

Conventional method of using radio active material for testing Type 1 diabetes in patients takes several days for detecting the condition, and in the meanwhile the diseases may become severe. With nanotechnology chip, it is very easy to detect in minutes.

Nanotechnology chip for Type 1 diabetes
Besides the radio active material used in conventional methods of detecting Type 1 diabetes in patients, this nanotechnology chip produces results quickly. It takes a small amount of blood through a finger prick. For detecting the antibodies this microchip depends on fluorescence based method.

The base of the microchip is coated with nanoparticle-sized islands of gold which show the fluorescent signal. This enables the antibody detection. This test recognizes the auto-antibodies levels quickly before they show the symptoms. Even a single auto-antibody will make you get into risk.

With conventional methods, doctors can’t exactly detect the type of diabetes the patient has.
Stanford university researchers developed this wonderful technology, which benefits the patients in many ways and they are also trying to launch this in the market very soon.

Benefits of nanotechnology chip for Type 1 diabetes

  • It is an inexpensive method for detecting Type 1 diabetes.
  • It requires minimal training for the technique to be used and reduces the burden for physicians.
  • Detection of Type 1 diabetes using this technology takes only a few minutes when compared to conventional treatment which takes a few days.
  • Early detection is the main advantage of this technology.
  • This chip can be used for performing nearly 15 tests.
  • It takes a small amount of blood compared to conventional methods.

Diode Laser – From Gum Diseases to Laser Root Canal Treatment

Filed under: 2014 — Tags: , — Ralph C Dreher @ 2:37 AM

Laser dentistry is an advanced technology in the dentistry. This technology existed from gum diseases to the root canal treatments. Dentistry is the home for laser technologies. It is not scary as the people imagine. Dentists enjoy the thrive of new technology.

Diode laser
Diode laser is a technology through which the patients are operated very smoothly in the soft tissues of the teeth. This is a compact device that generates a beam of light, which is focused on the targeted tissue of the mouth. When the light beam projects on that area it cuts away the damaged part by vaporizing it keeping safe the surrounding area. This also sterilizes the area and coagulates the blood vessels so that bleeding and infection will be in reduced amount. With this diode laser the traditional methods of drilling can be avoided which causes pain. There are several types of laser dentistry that includes hard tissues and soft tissues. The diode laser is mainly used to cut the soft tissues in the mouth. This laser can solve many problems like:

  • The diode laser can cure gum diseases. It removes the tissues affected and reshapes the gum. This improves the oral hygiene.
  • It any cancer sore occurs the diode laser reduces the pain and also reduces to not happen in the future again.
  • With diode laser, the gum reshaping can be done through soft tissue crown lengthening. This gives healthier root structure and also provides stronger base for the teeth.
  • With the diode laser, tooth whitening can be done in one hour.
  • Diode laser produces the pressure and heat to remove the infections in the teeth root with no drilling and hand files.

This treatment can be done without anesthesia and during the treatment the patient must use glasses to protect the eyes from radiations.

Benefits of diode laser treatment

  • The treatment is done in very less time
  • No side effects
  • Healing time is very less
  • This procedure causes less pain and bleeding or stitches
  • No local anesthesia is need to operate with this diode laser

Drawbacks:

  • Only the trained and experts can do this kind of treatments.
  • No dental insurance plans
  • It is expensive compared to the conventional methods.

This technology existed from many years and with this the patients and dentists will have many benefits.

Technical features and advantages of a Rotary engine

Filed under: 2014 — Tags: , — Ralph C Dreher @ 9:36 AM

A Rotary engine has a radial configuration and the cylinders are arranged around the crankshaft. In a radial engine, the pistons are connected to the crankshaft with a master-and-articulating-rod assembly. One piston attaches with the crankshaft using a master rod. The remaining pistons attach themselves to rings around the edge of the master rod. The number of the cylinders is always odd, to maintain uniformity in firing order which is important for smoothness.

Advantages
In rotary engines, smoothness is achieved easily than in other engines. Since rotary engines are air-cooled, they are less heavy and thus can be used in battle vehicles. A rotary engine has a comparatively shorter crankshaft, which means less vibration and thus higher durability.

Disadvantages
Since the engine is air cooled, cooling isn’t achieved perfectly. Since all the cylinders are exposed to airflow, it results in drag. Due to it’s bulk size, it also makes difficult pilot looking outside. They also cost a lot to maintain which is undesirable.

Usage
The usage of Rotary engines were limited until the World War II, when it was used in air crafts and tanks. The main reason behind its usage in tanks was that it had a good weight-power ratio and was considered better than the inline engines at the time.

Types
1) Multi-row rotary engine: As the size and requirements of the engine increased, it became necessary to increase the number of rows of the engine. The rows of cylinders are placed next to each other on different planes. However, they are joined to the same stationary crankshaft.

2) Diesel engine: Most rotary engines are built as gasoline engines. Diesel engines were made in 1920s and 1930s due to two advantages. Diesel engines consume less amount of fuel and they have a reduced fire risk.

3) Compressed-air engine: In compressed air rotary engines, air is used in the cylinders instead of fuel. It’s used mostly in model airplanes and gas compressors.

4) The Wankel engine: An engine that works with a similar principle as that of a rotary engine is the Wankel engine. It was developed by Felix Wankel in 1957. Like a piston engine, the Wankel engine also uses the pressure from combustion.

In a rotary engine, the pressure of combustion is held in the space created by a housing and a triangular rotor fixed inside it. Fuel is pumped into one of these chambers and is moved towards the ignition location. It also gets compressed because the housing surrounding it gets narrower. When it gets ignited, the rotor is pushed with force and the next chamber automatically draws in fuel towards compression and ignition. A Wankel engine has the advantage of fewer moving parts but the parts are expensive if they are to be replaced with.

The Automotive Technology – Drive-by-Wire

Filed under: 2013,Technology — Tags: , — Ralph C Dreher @ 8:42 AM

This system is designed with the help of engineering management system for vehicles. This is world’s first steering technology that allows to control independently a vehicle’s steering inputs and also tire angle. By transmitting the steering inputs, to the tires by mechanical link, the steering system directs the movements of tire.

In future, technology of the steering control the tire movements of the vehicle by electronic signals by reading the driver’s intention from steering inputs. The future system will transfer drivers’ intention even faster to the wheels than the mechanical system, by quickly communicating road surface feed back to the drivers. It increases the direct driving performance. This system will provide necessary performance by avoiding the unnecessary road generated disturbances.

This system receives the frequency signals, that is, when the vehicle is moving. This system is also called “by wire” or “x by wire”. This system mainly relies on electronics and the wide range of vehicle operations will control by it that includes braking, acceleration and steering. This systems will have the potential to increase the safety, functionality, comfort during the drive.

If you replace the systems like drive by wire and conventional throttle system, it can reduce the number of moving parts in your vehicle significantly. This increases operational accuracy, decreases weight and stretches out the time between the service visits for maintaining things like mechanical and other adjustments and some other by wire systems does not require service at all.

To enhance the driving capability further, the Nissan has developed a system that is camera based straight line stability. By making small input adjustments, the technology improves vehicle stability. The vehicle will, then, accurately trace and it will continue as planned in the lane as it is traveling. Due to cross winds or road surface the vehicle direction will change and the system acts to minimize the effects of the conditions will result in reduced steering input from the driver. (more…)

Symantec Report on Disaster Recovery Strategies by Indian SMEs

Filed under: Small Business — Tags: — Winson @ 2:32 AM

Global SMB Disaster Preparedness Survey conducted by Symantec Corp. reported about practices of disaster recovery strategies by Indian small businesses. The report also revealed the status of India’s small and medium sized businesses (SMBs) in being ready and prepared for recovery of disasters.

Natural disasters, malicious employee behavior, virus attacks, and changes in IT infrastructure were found to be main concerns for adoption of disaster recovery in India. The report revealed that data protection and recovery was taken care by IT departments in 42 percent of SMBs. Awareness on requirement and importance of disaster planning was increasing among other employees and also among small businesses. Owners and senior executives of about 39% of small businesses were involved in management and execution of disaster planning. In spite of the awareness of disaster recovery, some SMBs were not prepared for planning and execution.

The report revealed that 73 percent of respondents were satisfied with their disaster plans. Around 34 percent felt that they were protected in case of occurrence of a disaster. Most common outages were virus or hacker attacks, natural disasters, and power outages. These were prevalent among SMBs in India in 2009. However, many companies had no plan to deal with such situations. Due to lack of being prepared for disasters, SMBs had to spend a lot of amount and also lost the business.

According to the report, 18 percent of SMBs back up data on daily basis. However, only 50 percent of the company and customer data was backed up on a daily basis by some SMBs. About 59% of the customers complained loss of important data. As a result, materials and presentations were referred by SMBs for preparing a recovery plan. The report found that about 91% of the SMBs had no formal disaster preparedness plan.
