Importance of Drug Knowledge for the Manufacturers

February 22nd, 2015

An important part of drug studies, clinical research involves in testing new medicines, devices and surgical techniques on human volunteers. Bioavailability and Bioequivalence (BA BE) Studies in clinical research involve comparing the formulation of different drugs from different manufacturers or comparing the same drug prepared in different batches by the same manufacturer.

All drugs will have an active ingredient that does the main work of the medication. Bioavailability is a term that defines the extent to which this active ingredient is absorbed in the blood. The absorbed active ingredient should then be transported to the active site where it reacts to provide the right results. The level of absorption will determine the extent of the efficacy of the drug. BA or Bioavailability studies track and measure the amount of active ingredient absorbed in the blood. Based on these statistics for clinical research methodologies are then followed to determine the effects of the drug on the human being.ng.

The bioavailability studies of two drugs of almost similar formulations are studied to compare the effect and absorbency of their active ingredients. If the absorbance and therapeutic effect of two different drugs are similar, then they are said to be bioequivalent. Such drugs can be used interchangeably. For two drugs to be bioequivalent, they should pass various criteria. Their basic formulations should be similar, and the rate of absorbance should also be close. The dosage levels of the two drugs should be same and they should take relatively the same amount of time to reach the target site.

So, what are the benefits of doing BA/BE studies? First, they help us understand and determine if the active ingredient has any beneficial effect on the body. Secondly, if a drug manufacturer comes up with a different version of a medication that has an active ingredient that has already undergone a BA/BE clinical research studies, then they can just market that drug with minimum testing. The statistics obtained from its bioequivalent will prove to be good enough for satisfying the regulations. All drug manufacturers should do the BA/BE studies of the drugs they produce before it is introduced in the market.

This study is meant only for generic drugs and not specialized medicines. This clinical research study doesn’t have many phases and also involves just a small number of healthy volunteers. Moreover, the research is concentrated only on the active site, which means the studies can be done quickly and easily.

More Electronics Design And Circuit Diagrams Making Electronics Magazine More Popular

February 7th, 2015

In daily life we use different kinds of gadgets that make our life easier and better secured. Most of these products are based upon electronics technology. If we go for buying these products, we may expect heavy investment. However, there are certain electronics magazines or online electronics portals that provide all the information so that you could design and develop these gadgets by self. Display of electronics design and circuit diagrams make the understanding of any device easy and fun filled activity.

Recently I went through an electronics magazine having print and online versions. The write ups about Door lock controller and Driveway Alarm are very much convincing. The presence of such write ups show that how much useful these electronics magazine are for common man. Here is the importance information about both the devices that can be used in house or at office place to feel better secured.

Door Lock Controller

Door lock controller may be utilized to run an electromagnetic door lock or an electric strike. A little electromagnetic strike opens the door. The door lock controller presented here is an easy electronic switching circuit. Its electronics design uses a low-priced unipolar Hall Effect sensor IC MH183. This CMOS switch IC incorporates advanced chop stabilization technology to give exact and stable magnetic switch points. The design, performance and specifications are optimized for solid-state switching function. The internal output transistor is switched on in presence of adequately strong south-pole magnetic field. Likewise, the output is switched off through the presence of a weaker south field. After the sensor switch detects a powerful south-pole magnetic area in its vicinity, the remaining circuit is switched on for about TEN seconds. This delay maybe adjusted. After the correct sequence of triggers is applied, the electromagnetic door lock gets operational.

Driveway Alarm

You may install Driveway Alarm inside a driveway to detect a person, vehicle or big animal. It sounds an alarm when any interruption takes place. Circuit diagram contains 2 modules: receiver and transmitter. The laser pointer is powered via the 9V DC supply available from the receiver module. Installation of receiver and transmitter modules is detailed in separate layout. Working of receiver module is very easy. In the beginning, when power is applied to the system, it is in standby mode. Once the laser beam is interrupted by an object, person or animal, the photo-sensor energizes the rest of the circuit to buzzer the sounds.

A specific section named circuit lab is especially dedicated to electronics design and circuit diagrams of commonly used devices and this feature further enhances the importance of online electronics magazines.

Proper Disposal Of Consumer Electronics Is Important

February 4th, 2015

When you think about consumer electronics, you may think of equipment you use every day; like televisions, mobile phones and personal computers. What you may not even consider is that each year, the United States alone generates almost 3 million tons of commodity and electronic waste (or e-waste) through the disposal of damaged, defective and obsolete devices, such as that cordless phone that quit working for you or those mobile phones you threw away because you wanted the latest models. Let’s look at where that e-waste ends up after it’s tossed away and the effects it has on you and the environment.

Because of the difficulty and cost of recycling electronics, as well as spotty enforcement of legislation regarding e-waste exports, vast amounts of used electronics have been sent to countries such as China, Kenya and India. Lower environmental standards and working conditions make processing e-waste more profitable yet dangerously hazardous in those countries. Being mindful of e-waste disposal is a big concern. There are facilities out there that specifically deal with this hazardous material correctly.

When electronics are handled and sorted properly, e-waste is a valuable source of secondary raw materials. However, they are a major contributor of toxins and carcinogens when clumsily treated.

Fast paced technology changes, low initial cost and actual planned obsolescence have given way to a growing problem around the globe. Uncontrolled burning, disassembly without safety measures in place, and haphazard disposal practices are causing environmental and health problems.

Toxic and carcinogenic substances in waste from consumer electronics include lead, cadmium, mercury and polychlorinated biphenyls (PCBs). When not handled properly, these substances can seep into soil where food is grown. They can be eaten or absorbed by animals in our food chain. Illegal burning of these electronics causes toxic fumes to be emitted, which are inhaled by animals and humans and depletes the ozone.

There are many ways in which these substance cause serious health risks. Lead, cadmium and mercury levels can build up in the body over time causing damage to the central nervous system, renal failure and cell damage. PCBs are known carcinogens.

Think about it the next time you indiscriminately throw away those cordless phone batteries or that camcorder that is older than your parents. Proper disposal through an e-waste recycler helps save our environment. With the potential for mercury, cadmium and lead leaching into the soil and contaminating the food chain, as well as PCB exposure causing cancer, some thoughtful consideration of use, reuse and disposal of consumer electronics is essential.

What Are The Advantages Of Using Electronic Tilt Sensors In Off-road Vehicles

January 25th, 2015

Off-road vehicles are designed to perform the most difficult tasks in often in the most extreme outdoor conditions. In industries like construction, forestry and agriculture, vehicles often have to navigate on uneven surfaces and slippery terrain whilst lifting and manoeuvring heavy and uneven loads. This can present difficult challenges for the drivers of these vehicles: for many vehicle operators, the chances of tipping or rolling the vehicle over are high, so obviously safety is a paramount concern. However, electronic sensing technology is now available which makes the vehicle drivers job easier and safer. As these electronic sensors can detect the vehicles operating condition and alignment, the safety of the operator is greatly increased.

Tilt Sensors Monitor the Safe Horizontal Alignment of Vehicles
Off-road vehicles often have to work in extreme conditions, where rugged terrain and heavy moving machine parts can quickly shift the balance of a vehicle. A shift in the dynamics of the vehicle or an uneven transfer of weight or dangerous alignment can cause hazardous conditions for the vehicle operator. Electronic sensors can help operators to monitor the horizontal alignment of vehicles. Tilt sensors can precisely detect even the slightest angle variation. Tilt sensors can give the driver accurate information about the exact road-grade angle, the boom angle, the platform angle and the crane-level angle. Armed with this important information, an operator can then take action to avoid a potentially disastrous situation.

Tilt sensors, however, need to sturdy and resilient. They have to be able to withstand the extreme shock, vibration, and all the harsh elements associated with outdoor use. Moreover they also have to be able to cope with direct exposure to chemicals, dirt, moisture, sunlight, and electrical interference. Therefore tilt sensors have been designed so that they are capable of resisting these elements and are able to perform in extreme environments. They are able to do so because of certain special design features like:

Compact housings rated for IP67 protection which encase and protect the electronics from chemicals and liquid ingress,
UV-resistant plastic and metal housings which prevent damage from exposure to sunlight,
Noise-immune technology which enables the sensors to ignore conducted and radiated electrical noise.
Outputs protected from short-circuits and overloads which eliminate damage during installation,
LHighly flexible cables, which are armoured to resist chemicals and perform at temperatures as low as 40 F.

Sensing technologies
There are two very different, yet highly effective sensing technologies that can be applied to verify the horizontal alignment of off-road vehicles: electrolytic tilt sensing and micro electromechanical sensing. (MEMS)

Electrolytic tilt sensing
Electrolytic tilt sensing technology can measure the tilting of a reference plane in two axes, by measuring the tilt angle with reference to the earths ground plane, using an accelerometer. At the centre of the sensors core are measuring cells surrounded by fluid or liquid. These measuring cells monitor ant change in the liquids conductivity to detect angle variations and deviations.

MEMS sensing technology
The second technology is micro electromechanical sensing (MEMS). When a vehicle lifts or tilts, the movement is transferred to the beams of the sensor that deflect to take the inertial force of the mass. The change in capacitance is proportional to the tilt of the sensor, which is ultimately then converted to a change of voltage and transferred as an analogue value to the driver of the vehicle. The use of MEMS sensors incorporating this technology are better suited to applications where a single-axis wide tilt angle (90) and lower precision (1) are needed.
