Intermittent Fasting

I watched Dr Michael Mosleys recent TV program with a great deal of interest due to having recently started a diet/training program that would get me on course to regain some of the youthful fitness Id let slowly slip away in the years since I turned 30. The BBC trailed the program with this article on the BBC website http://www.bbc.co.uk/news/health-19112549

Now, 3 months later and 12 fast days on, Im happy to say that, whilst each fast has been a mild challenge of my discipline and my dedication, it has for the most part been a really positive experience. There has been only one lapse and that came during the school holidays when I made a plate of Italian style meatballs in tomato sauce for my son. This would have been a challenge all of its own to have to deal with the sights and smells of making such a delicious meal however having only just come through that challenge with rumblings coming from down below, when my son decided the meatballs were too spicy for him and placed the hardly touched plateful back in the kitchen the game was up.

So I fell off the wagon once, not because I was too hungry to stick to the plan but simply because my desire to quit overcame my desire to hold firm. But, for the most part and through the 36 hours of each fast "day", I have resolutely stayed on course. Lets face it, its not so desperately difficult to go without for that long. The habit of eating is what usually presents the most challenges. During each fast, despite drinking plenty of water and training reasonably frequently throughout, I have been losing approximately 3 - 4 pounds. Granted it does mostly come back on the following day but not all of it does. The trajectory throughout the 3 months this experiment has taken place has been of consistent weight-loss and I place the  weekly fasts as a core part of this.

I sometimes ask myself why bother fasting. Is it for the weight-loss or the detox? For me the answer is neither. Its partly an allusion to the disciplined routine of the diet I have been trying to follow through the rest of these weeks but its mostly because of all the softer reasons suggested in the BBC program mentioned previously. For those who haven't seen the documentary, it is claimed that short bursts of intermittent fasting have the capacity to kick the body out of gear and into a mode whereby the processes of repair and rejuvenation take centre stage. These effects and my perception of them may be placebo in nature but I certainly feel that my periods of abstinence are doing something good in there. Its almost an uncanny feeling of strained well-being that takes hold when the fast is in full swing.

So, in conclusion, as I lie in my bed with my laptop, 24 hours into my latest 36 hour fast, getting ready to go to sleep and dream about potato crisp forests and boats sailing across oceans of tikka masala bordered by pilau rice beaches, I feel sure that what started as an experiment brought on by a passing interest in a compelling BBC TV documentary has now become something that I may well be participating in this time next year or who knows even further down the line. So if you're reading this post feeling bloated and full after a late evening meal, why not consider for yourself if the benefits of Intermittent Fasting might be something that has a future in your weekly routine.

Incandescent Bulbs

For years now we've been hearing the reports that the days of the incandescent light bulb are numbered. In actual fact they may have already got to zero as it is almost impossible to get hold of these old style bulbs for love nor money.

Its yet another front in the constant battle between the freedom for individuals to choose and the "nanny state knows best" attitude that seems forever present from certain sections of society.

Those of us, (and there are many), who dont particularly enjoy the thought of spending the rest of their lives in dimly lit dingy rooms lit badly by low energy fluorescent bulbs have no option but to grin and bear it as the rules slowly change the world and what we are allowed to do in it.

Or do we? It would appear that sales of multiple spotlight style bulb fixtures have taken on a life of their own in recent years. I myself use them in almost every room in my house now and the wattage when aggregated together can supply the bright light we used to associate with our 100 or 150 W bulbs. So it would seem there is a solution for us and a way around the poorly thought out and imposed from on high regulations which the climate fundamentalists have been allowed to push through.

I just wonder though if they really thought before the rule change was implemented. After all in the language of the climate fundamentalist, everything comes down to carbon. The carbon used to manufacture all of these elaborate multi-bulb light fixtures as well as the electricity consumed by 4 of the 60W spotlight bulbs surely has to be more than that consumed by a single 100W bulb as would have been used beforehand. Their crazy logic has forced those of us who don't particularly want to live our evenings in dingy rooms to consume far more energy and use up far more carbon that we did before. Yet another example of the climate fundamentalists need to throw themselves shrieking headlong into every half baked initiative but failing spectacularly and doing exactly the opposite of what was intended.

Satellite Antenna Pointing Line Of Sight Obstruction Calculator

It is important to have a clear line of sight between the antenna and the satellite.

In the latitudes of the planet closer to the poles, the lower antenna elevation angles required increase the likelihood of obstructions on the ground coming between the antenna and the satellite. The calculator below displays the distance the antenna needs to be from a potential obstruction in order to ensure a clear line of sight for a given elevation.


This tool can be used for all obstacles from trees near a house to mountains in the distance.




if(isset($_POST['act'])
&& !empty($_POST['z1'])
&& !empty($_POST['z2'])
&& is_numeric($_POST['z1'])
&& is_numeric($_POST['z2']))
{
if($_POST['act'] == 'sub')
{
$calc = ($_POST['z1']/tan(deg2rad($_POST['z2'])));
$op = '-';
}
if($_POST['act'] == 'add')
{
$calc = ($_POST['z1']/tan(deg2rad($_POST['z2'])));
$op = '-';
}
echo '

The antenna will need to be '.$calc.' metres from the obstacle.


Go back and carry out another calculation.

';

}else{
echo '

Select the appropriate satellite you will be using:





Please enter the height of the obstacle above the level of the antenna in metres -


Please enter the elevation angle in degrees for the satellite in use -

Understanding Polarisation

There are two major types of polarisation: Cross Polarisation (Cross-pol) and Co Polarisation (Co-pol).

Looking at cross polarisation initially, there are two types of cross polarization namely circular and linear. Within the circular realm there is the Left Hand Circular, or LHCP, or Right Hand Circular, or RHCP. This type of polarization is used in C-Band and in X-Band. One would be hard pressed to find circular polarization on Ku, K or Ka band frequencies. Linear polarization on the other hand is used frequently on Ku and Ka band antennas. With linear there are two types: Horizontal and Vertical.

What exactly is happening in the linear world that we need to know about? Before understanding how linear is used, one must understand the device being used on the satellite dish to let one signal pass while blocking the other signal. This is called the Orthogonal Mode Transducer, or OMT for short.

To use the channels that are available for satellite broadcast as efficiently as possible, both horizontal and vertical polarization (and left- and right-hand circular polarization) can be applied simultaneously per channel or frequency. In such cases the frequency of one of the two is slightly altered, to prevent possible interference. Horizontal and vertical transmissions will therefore not interfere with each another because they are differently polarized. This means twice as many programs can be transmitted per satellite. Consequently, via one and (almost) the same frequency the satellite can broadcast both a horizontal and a vertical polarized signal (H and V), or a left- and right-hand circular polarized signal (LH and RH).

The ASTRA2Connect system uses cross polarisation and our users can use this page to check the correct polarisation of their own systems. ASTRA2Connect polarisation checker.
