Secure systems: Ensure your business systems (PCs, file servers, and mail servers) are protected by trustworthy internet security business products and are using the latest updates. Consumer solutions (paid or free) are not sufficient to provide adequate coverage and visibility for the security of your business.
Dedicated online banking PC: Designate a single computer to use as your business’s online account machine. This computer should solely be used for online banking and not for other activities such as e-mail, web browsing, or file sharing.
Consult with your bank: Discuss with your bank the type of security they have in place and other best practices it can recommend based on its systems. Also, familiarize yourself with the protection and processes it provides to business accounts in the event of losses.
Learning the Lingo
Trojans: Programs that perform malicious actions but have no replication abilities. Like the original Trojan horse, these programs may arrive as seemingly harmless files or applications, but actually have malicious intent within their code. Banking Trojans are specifically designed to gain
Allow for flexibility. With face-to-face training, you usually get one chance to soak it all in. But many online programs are on-demand, meaning learners can move at their own pace and watch presentations again and again if needed.
“The added flexibility allows everyone to work at his or her own pace and better fit the training into a busy schedule,” Walsh says. “For instance, the technology training that we buy for our developers consists of a series of videos covering a topic. During the videos, the instructor works on a project and our developers follow along, recreating that same project. They’re constantly pausing, rewinding, or replaying the videos. The developers prefer this style of training, and it’s not possible offline.”
For a monthly subscription fee of about $50, Treehouse offers unlimited access to more than 650 training videos, including quizzes and challenges, to keep employees updated on everything related to designing and developing programs for the web and mobile devices.
Go mobile. Online education also allows for flexibility across technology formats. Employees can learn at home, on the job,
1. Store documents with Google Drive, Dropbox, Skydrive and Box.
If you’re a technophile, hopefully these are obvious and you can skip this section. If not, and you haven’t started relying on these services as your file storage solution, this is absolutely critical for you. Stop storing your files on laptops, desktops, tablets, or mobile phones. The mantra that I live by — and consistently push in my role as CTO — is access to data from anywhere, at any time, using any device. If your files are stored on your laptop, which you left at home, you can’t do that.
Google Drive is my personal and professional data hub. Dropbox, Skydrive, and Box all provide the same functionality. I don’t store any data on my devices, thus eliminating the fear of losing the device, breaking the device, or leaving it at home when I need some files from it at work. The beauty of cloud-based data storage is that I always have access to it.
The argument that these services may go down or aren’t as secure
Wave power is the transport of energy by wind waves, and the capture of that energy to do useful work – for example, electricity generation, water desalination, or the pumping of water (into reservoirs). A machine able to exploit wave power is generally known as a wave energy converter (WEC).
Wave power is distinct from the diurnal flux of tidal power and the steady gyre of ocean currents. Wave-power generation is not currently a widely employed commercial technology, although there have been attempts to use it since at least 1890. In 2008, the first experimental wave farm was opened in Portugal, at the Aguçadoura Wave Park.
Waves are generated by wind passing over the surface of the sea. As long as the waves propagate slower than the wind speed just above the waves, there is an energy transfer from the wind to the waves. Both air pressure differences between the upwind and the lee side of a wave crest, as well as friction on the water surface by the wind, making the water to go into the shear stress causes the growth of the waves.
Wave height is determined by wind
That’s great news for Bowles, whose company offers a self-serve kiosk that buys back used electronics (mostly mobile phones) directly from consumers. The e-waste is sold either to refurbishers, who resell the wares around the world, or to recyclers, who strip them down for the plastic and metals
Always erase your data before you sell or recycle your old devices. The easiest way is to run a Google search for the “factory reset” option for your device, then follow the instructions. This takes just a few keystrokes and usually does a good job. However, it won’t stop a data-recovery expert with sophisticated tools who’s motivated to recover your information. If you’re really concerned about your legacy data, remove the hard drive completely and either keep it or disable it–a drill press or hammer will do the job.
It’s rare. Most hackers looking for valuable data target specific people instead of mining through random devices in the recycling process. Reputable recycling firms strive to reach 100 percent erased on any used electronics they handle, because it can be a big liability. They want to protect your data as much as you do. Best insurance policy? Erase your
Rebooting or restarting is the way to go if your phone or tablet starts acting funny, or maybe showing a bit of sluggishness. If you experience one of those symptoms all you need to reboot is press the power button and choose restart. This is also known as a “soft” restart.
But what if you device freezes, goes blank, or becomes unresponsive and you can’t get to that menu… What do you do then?
You can go for what is known as a “hard” reboot. Depending on your device, this can be achieved by pressing a combination of buttons. In most Android devices, you have to simultaneously press the power and volume down buttons for 5 seconds. This should work for any stock Android device like Google Nexus and Google Pixel, Samsung Galaxy, and LG phones.
Some other devices, like most Motorola phones are slightly different, the procedure is the same but instead of using the volume down button you use the volume up button.
If you need to reset your Android device to its factory state (a common reason is if you’re selling and moving to a new phone), there are two ways
Nanotechnology (“nanotech“) is manipulation of matter on an atomic, molecular, and supramolecular scale. The earliest, widespread description of nanotechnology referred to the particular technological goal of precisely manipulating atoms and molecules for fabrication of macroscale products, also now referred to as molecular nanotechnology. A more generalized description of nanotechnology was subsequently established by the National Nanotechnology Initiative, which defines nanotechnology as the manipulation of matter with at least one dimension sized from 1 to 100 nanometers. This definition reflects the fact that quantum mechanical effects are important at this quantum-realm scale, and so the definition shifted from a particular technological goal to a research category inclusive of all types of research and technologies that deal with the special properties of matter which occur below the given size threshold. It is therefore common to see the plural form “nanotechnologies” as well as “nanoscale technologies” to refer to the broad range of research and applications whose common trait is size. Because of the variety of potential applications (including industrial and military), governments have invested billions of dollars in nanotechnology research. Until 2012, through its National Nanotechnology Initiative, the USA has invested 3.7 billion dollars, the European Union has invested 1.2 billion and
Solar cell efficiency refers to the portion of energy in the form of sunlight that can be converted via photovoltaics into electricity.
The efficiency of the solar cells used in a photovoltaic system, in combination with latitude and climate, determines the annual energy output of the system. For example, a solar panel with 20% efficiency and an area of 1 m2 will produce 200 W at Standard Test Conditions, but it can produce more when the sun is high in the sky and will produce less in cloudy conditions and when the sun is low in the sky. In central Colorado, which receives annual insolation of 5.5 kWh/m2/day, such a panel can be expected to produce 440 kWh of energy per year. However, in Michigan, which receives only 3.8 kWh/m2/day, annual energy yield will drop to 280 kWh for the same panel. At more northerly European latitudes, yields are significantly lower: 175 kWh annual energy yield in southern England.
Several factors affect a cell’s conversion efficiency value, including its reflectance efficiency, thermodynamic efficiency, charge carrier separation efficiency, and conduction efficiency values.Because these parameters can be difficult to measure directly, other parameters are measured instead, including quantum efficiency, VOC ratio, and fill factor. Reflectance
Maglev (derived from magnetic levitation) is a transport method that uses magnetic levitation to move vehicles without making contact with the ground. With maglev, a vehicle travels along a guideway using magnets to create both lift and propulsion, thereby reducing friction by a great extent and allowing very high speeds. In itself, maglev technology includes no moving parts.
Maglev trains move more smoothly and more quietly than wheeled mass transit systems. The power needed for levitation is typically not a large percentage of its overall energy consumption; most goes to overcome drag, as with other high-speed transport. Maglev trains hold the speed record for trains.
Compared to conventional trains, differences in construction affect the economics of maglev trains, making them much more efficient. For high-speed trains with wheels, wear and tear from friction from wheels on rails accelerates equipment wear and prevents high speeds. Conversely, maglev systems have been much more expensive to construct, offsetting lower maintenance costs.
Despite decades of research and development,
The invention of the printing press is considered by many to be the one of the most important technological inventions of our time. Since then, there have been many following “inventions of new media for the transmission of information among persons” (Eisenstein 3). From telegraph to television, society seems to have been bombarded by a plethora of new technologies since the printing press. However, there was nothing that could have prepared the fledgling field of technical communication for the rapid development of the computer industry and subsequently the Internet. Descriptions of these events note that “the term ‘desktop publishing’ did not even exist before 1985, and yet 1986 and 1987 have been banner years for books, magazines, and videotapes on the subject” (Brockmann 30). Texts of the time also describe how the rapid development and adoption of the Web created a “snowball effect of exponentially rising numbers of readers and writers” (Berners-Lee 80). There seems to be no question as to the speed at which these technologies came into fruition, but how did desktop publishing (DTP) and the Internet specifically affect practicing technical communicators and the profession?
The topic of “technology” is practically unavoidable in discussions about
Electricity was first discovered in the 1700s by Benjamin Franklin who performed the first electricity experiment in history. Since then, many others including Ampere, Faraday, Ohm, and Oersted managed to develop simple electrical devices after having understood the basic electrical principles. Much later, in 1904, Fleming’s diode opened a new horizon for the advent of electronic components.
Electrical technology deals with all machines, tools, devices, and systems in which a current or a flow of electrons takes place through conductors and metals. It involves the design and development of high-voltage systems and components such as motors, generators, heaters, electrical power transmission and distribution systems, radio wave and optical systems, converters, and control systems for operating light and heavy machinery. Almost all of our low or high-tech gadgets today involve the use of electrical current to operate, making electrical energy the main- and possibly the only- factor to define what electrical technology is.
Electrical technology however, not only involves the design and production of all the electrical systems mentioned, but also the installation, testing and maintenance of these systems. A number of challenges arise with the implementation of mathematics, science, and engineering to develop these modern wonders.
Role of the Nuclear Medicine Technologist, RT(N) and/or CNMT
The nuclear medicine technologist is an allied health professional who, under the direction of an authorized user, uses special equipment to make images of areas of a patient’s body.
Nuclear medicine technologists prepare and administer radioactive materials that cause abnormal features to appear different from normal areas in the images. They follow strict safety procedures to protect themselves and their patients as they capture these images for diagnosis, treatment and research.
Ongoing continuing education and professional growth are essential. Nuclear medicine technologists must maintain the skills required to perform their tasks and to enhance the quality of patient care
The philosophy of our Nuclear Medicine Technology Program is that a curriculum should prepare you to acquire the knowledge, skills and attitudes that will move you through a full and productive life as a medical imaging specialist.
The foundation set forth at TCC should prepare you to cope with changing environments and technologies as well as help you meet occupational and personal challenges.
To provide you with the knowledge and skills necessary to enter the field of Nuclear Medicine Technology through
Polarized Lens Technology
Polarized lenses have an invisible horizontal filter integrated into the lens, which is designed to eliminate reflected light (aka glare). When sunlight reflects off a surface, it becomes concentrated and even more intense. Polarized lenses filter out 99.9% of this reflected, intense glare. Polarization is recommended for bright sun and variable light conditions and the benefits are fully maximized on or around water.
Photochromatic Lens Technology
We all know the hassles of constantly changing light conditions whether on the trail or in the car. Photochromatic technology automatically darkens the lenses in sunny conditions and lightens them in shadowed or cloudy conditions in a matter of seconds. So how exactly does this happen? Photochromatic lenses are made up of trillions of organic molecules that rapidly change structure in the presence of UV light. In bright sunlight, the molecules expand in size, darkening the lenses while in low light conditions the molecules shrink allowing more light to filter through.
Interchangeable Lens Technology
Interchangeable lenses are the tried and true solution for battling inconsistent light conditions. Smoke lenses are best for bright sun conditions, while copper lenses are best for cloudy conditions, and clear lenses are optimal for very
There are a variety of different semiconductor materials used in solar cells. Learn more below about the most commonly-used materials.
Silicon is, by far, the most common material used in solar cells, representing approximately 90% of the modules sold today. It is also the second most abundant material on Earth (after oxygen) and the most common semiconductor used in computer chips. Crystalline silicon cells are made of silicon atoms connected to one another to form a crystal lattice. This lattice provides an organized structure that makes conversion of light into electricity more efficient.
Solar cells made out of silicon currently provide a combination of high efficiency, low cost, and long lifetime. Modules are expected to last for 25 years or more, still producing more than 80% of their original power after this time.
A thin-film solar cell is made by depositing one or more thin layers of PV material on a supporting material such as glass, plastic, or metal. There are two main types of thin-film PV semiconductors on the market today: cadmium telluride (CdTe) and copper indium gallium diselenide (CIGS). Both materials can be deposited directly onto either the

Don’t Run It Down to Empty
Squeezing every drop of juice out of a lithium ion battery (the type used in today’s laptops) strains and weakens it. Doing this once or twice won’t kill the battery, but the cumulative effect of frequently emptying your battery will shorten its lifespan.
(There’s actually an exception to this rule–a circumstance where you should run down the battery all the way. I’ll get to that later.)
The good news: You probably can’t run down the battery, anyway–at least not without going to a lot of trouble to do so. Most modern laptops are designed to shut down before the battery is empty.
In fact, Vista and Windows 7 come with a setting for just this purpose. To see it, click Start, type power, and select Power Options. Click any one of the Change plan settings links, then the Change advanced power settings link. In the resulting dialog box, scroll down to and expand the Battery option. Then expand Critical battery level. The setting will probably be about 5 percent, which is a good place to leave it.
XP has no such native setting, although your laptop may have a vendor-supplied tool that does the same job.

Research the Audience
What is this new social network or affinity group all about? Is your potential customer in this group? To find the answers to these questions, spend some time looking at the demographics of the typical member. You can often find them by reviewing the information on the about page or the advertising section of the website. Check out third-party information on the community–this may include blogs, media outlets or research groups. Look for research that shows outcomes, not just the demographic or membership information.
Talk to the people who invited you to join. What are they getting out of this new group? How much time do they spend networking with people? Have they closed business from relationships built on this new social network? What other value have they found
Social networking–like any form of networking–is about dedicating time. You have to spend time connecting with people, sharing ideas and understanding if they are a good fit for you or the possible lead you will send them. Investing time is the only way to reach this goal. Checking in for 10 minutes a day to update your profile status is not going
Most business leaders recognize that the right tech expert can offer distinct competitive advantages, but let’s face it: Most small businesses just don’t have the resources to maintain a cadre of go-to IT specialists. At best, there’s one beleaguered tech guy slogging through the company’s computer problems and recommending purchases. At worst, it’s that one overworked person in accounting who also “knows a lot about computers.”
It’s for these reasons that small businesses should consider relying on trusted technology resellers and service providers to do a lot of the technological legwork for them. These partners can help a small organization choose the most suitable technologies for a big project, aid in their deployment and potentially take over the care and feeding of these systems.
But selecting the wrong reseller or service provider can have disastrous consequences, which is why it pays to do your homework before partnering up, says Todd Thibodeaux, president and chief executive officer of the Computing Technology Industry Association (CompTIA), an IT industry trade organization.
“There’s a whole set of things you have to look at,” he says. “Things like uptime and what’s their time to fix problems when
