Colour management systems are designed to address the Problem of device variabilitv, adiusting: the colour rela- ~ usually provide profiles for a wide range of devices from ‘ ,’ I ” tionihips between devices to ensure consistent colour throughout the publishing process. A CMS translates colours ~ which the can select. from the colour-gamut, or colour space, of one device into a ‘neutral’ device-independent colour space, and then fits that colour information to another device’s colour gamut by a process called colour mapping. The CMS obtains the colour characteristics of each device from its device profile in one method, the…

Calm the patient. Then immerse the affected area in a bowl of cold water containing ice cubes and a teaspoon of baking powder, which slows the circulation and helps prevent the spread of poison. Alternatively, apply fresh raw onion over the area or cover with wheat germ oil, put an ice pack on top, or apply calendula ointment. This should be done before anything else. Give Dr. Bach Rescue Remedy (a fl ower remedy available from specialist shops and pharmacies), arnica (a homeopathic remedy), or a few drops of lobelia leaf tincture. Serious allergic reactions need to be treated with…

Science is not about big words. It’s not about lab coats and safety goggles, and it’s definitely not about trying to make yourself sound fancy. Science is not an end in and of itself, but a path. It’s a method to help you discover the underlying order of the world around you and to use those discoveries to help you predict how things will behave in the future. The scientific method is based on making observations, keeping track of those observations, coming up with hypotheses to explain those observations, and then performing tests designed to disprove those hypotheses. If, despite…

In 2013, I had the opportunity to speak on a lowcarb cruise hosted by my friend and coauthor Jimmy Moore. (Check out our book The Ketogenic Cookbook.) While I was on the cruise, one of the ketogenic doctors who spoke asked why I allow sweet treats even if they are made with stevia or Swerve (a natural sweetener like stevia). I proudly stood up, found my most confident voice, and explained that I have two young children who are bombarded with images of cupcakes, candy, juice boxes, and sugary cereals, all in fake bright colors to capture their attention. So…

We live in a highly visual world. Most of what we do is supplemented by graphics and images to help convey meaning. An earlier book by the author – Digital Graphic Design – was conceived as a DIY guide to the rich array of resources now available to the digital designer and to the use of these resources to create a wide range of graphic effects. Over 300 black and white graphics created with the use of leading edge drawing, painting, photoediting and three-dimensional applications were demonstrated and explained in a monochrome environment. Digital Colour in Graphic Design is a…

Each voluntary transaction involves consumer and producer surplus (CS and PS) as described in the appendix. There may be no greater benefit from legalized casino gambling than the enjoyment consumers receive from the activity. After all, consumers vote on their favorite goods and services with their spending. The consumer benefits from gambling are likely to be much greater than tax revenue or employment growth benefits from casinos. Several authors have acknowledged this (Eadington 1996; APC 1999; Walker and Barnett 1999; Collins 2003) but most researchers discount or ignore it (Grinols and Mustard 2001; Grinols 2004). Yet, consumer benefits are critical…

Wireless networks have been notoriously insecure since the early days of the 802.11b standard of the late 1990s. Since the standard’s inception, major 802.11 weaknesses, such as physical security weaknesses, encryption flaws, and authentication problems, have been discovered. Wireless attacks have been on the rise ever since. The problem has gotten so bad that two wireless security standards have emerged to help fight back at the attackers: These standards have resolved many known security vulnerabilities of the 802.11a/b/g protocols. As with most security standards, the problem with these wireless security solutions is not that the solutions don’t work — it’s…

The fact that nature endowed us with two eyes, which are separated by a few centimetres, means that the objects we view appear slightly different to each eye; this effect provides a sense of depth and can be used, in graphic design, to produce stereoscopic three-dimensional images on a twodimensional surface. Experimentation has shown that, if we view a scene with the eyes at rest, then our field of view is defined by a cone – our ‘cone of vision’ – of angle approximately 60″. This field of view can be thought of as analogous to that seen through the…

Colour depth, sometimes called bit depth, refers to the maximum number of colours which can be stored in an im- .age file. A 1-bit file stores two colours (usually black and white) and can be described as 1-bit deep since all the information required to specify each of the dots making up the image can be stored in a 1-bit number (0 for black or 1 for white). A 2-bit file stores four colours, a 4-bit file stores 16 colours, an 8-bit file stores 256 colours and a 24-bit file stores 16 million colours. A greyscale image is an 8-bit…

The liver is the largest organ in the body and one of the most important for overall health. It is situated under the lower right rib cage. The liver is capable of complete self-renewal at a faster rate than the rest of the body. Given this ability to restore itself via good foods, rest, and herbs, the root meaning of its name, “live” or “life,” is very apt. The liver makes and releases into the body an amazing amount of useful substances and sustains us in a myriad of vital ways. It also stores vitamins, minerals, and sugars. Defi ciencies…
