Sandhamn (Swedish for "Sand Harbour") is a small settlement in the central-peripheral part of the Stockholm Archipelago in central-eastern Sweden, approximately 50 km (30 mi) east of Stockholm. Sandhamn is located on the island Sandön ("Sand Island"), which is, however, colloquially referred to as Sandhamn.
One of the most important natural ports in the archipelago with easy access to the Swedish capital, Sandhamn has been popular for pleasure boating since the late 19th century. It is known for its tavern, its clubhouse, and its harbour.
The island is approximately 9 km (5.6 mi) long and 6 km (3.7 mi) and consists mostly of sand and is dominated by beaches, dunes and especially pine forests.
Sandhamn receives an additional 100,000 visitors annually.
"Viveca Stens" popular novels come to life in "The Sandhamn Murders", a perfect mix of Nordic crime & the beautiful surroundings of the outer Stockholm archipelago.
Sandhamn (le nom veut dire port de sable) est une petite île de Suède située sur la mer Baltique. La population de ce petit port de pêcheurs n'excède pas les 110 habitants. Le tourisme y est développé grâce à des liaisons maritimes Stockholm-Sandhamn régulières en été.
Cette île est le lieu où se déroule l'action du roman La Reine de la Baltique de l'auteur Viveca Sten. Une adaptation de ce roman pour la télévision est diffusée en France sous le titre de "Meurtres à Sandhamn".
In the beginning of August, while I was driving around Straumoya, I saw something orange in my peripheral vision. But I paid attention to the road and drove a bit further.
When I looked to the left again, I realized a fox was lying there, and a second later, that it must be a cub. It was lying there, basking in the sun!
I quickly ran to the back to grab my camera, and when I came back, it was still there, "thankfully."
But my camera wouldn't focus. "Damn, I hope it's not broken."
After a few more failed attempts, it finally clicked.
My autofocus was set to 10 meters and further, "Smart guy me!" After a few shots, I got out of my camper to take a closer shot. "I hope it doesn't run away."
"It's not running away at all, it's coming closer," so close that I have to zoom out to keep it in the frame.
He sits down, leisurely and curious, staring at me. He has certainly never seen such an old sock like me before!
When I look at this image now I still feel the marvel of this wonderful encounter and the joy of seeing such a curious little animal that didn't show any anxiety at that moment.
This is a computer mouse that glows when it’s in use. The orange bit pulsates. There is also a dock that charges the mouse and that is the green light on the picture. HMM
The great gate (darwaza-i rauza) that leads from the north of the jilaukhana to the garden, and ultimately to the mausoleum of Mumtaz Mahal, is a large structure with triadic openings. Looking at the south elevation, the base of the gate measures nearly 38 meters and its peripheral walls, including the cupolas, are 30 meters in height. The central pishtaq, also including the cupolas, is 33 meters in height and 19 meters wide. The gate is composed of red sandstone with decorative panels and accents in white marble. The surface treatment of the pishtaqs is elaborate: it is framed in white marble and inlaid with precious stones. Its central arch is delineated by a triple rope moulding and surrounded by a frame containing the Daybreak Sura (Sura al-Fajr) in thuluth script. The entry iwan contains muqarnas in red sandstone, which contrast with the white plaster paint outlining each segment. (The northern elevation of the gate is identical to the southern one; the lower left corner of its framed inscription also contains the signature of the calligrapher, Amanat Khan). Topping the central pishtaq is a series of eleven arches in red sandstone, capped by a chajja; eleven white marble chhatris crown the chajja. A single column rises from the pishtaq to complete each end of the arcade; this column terminates in a finial above the chhatris. This same column runs in engaged form along the height of the pishtaq itself.
Taj Mahal, the pinnacle of Mughal architecture, was built by the Mughal emperor Shah Jahan (1628-1658), grandson of Akbar the great, in the memory of his queen Arjumand Bano Begum, entitled ‘Mumtaz Mahal’. Mumtaz Mahal was a niece of empress Nur Jahan and granddaughter of Mirza Ghias Beg I’timad-ud-Daula, wazir of emperor Jehangir. She was born in 1593 and died in 1631, during the birth of her fourteenth child at Burhanpur. Her mortal remains were temporarily buried in the Zainabad garden. Six months later, her body was transferred to Agra to be finally enshrined in the crypt of the main tomb of the Taj Mahal. The Taj Mahal is the mausoleum of both Mumtaz Mahal and Shah Jahan.
The mausoleum is located on the right bank of the river Yamuna at a point where it takes a sharp turn and flows eastwards. Originally, the land where the Taj Mahal presently stands belonged to the Kachhwahas of Ajmer (Rajasthan). The land was acquired from them in lieu of four havelis as is testified by a court historian, Abdul Hamid Lahauri, in his work titled the Badshah-Namah and the firmans (royal decrees). For construction, a network of wells was laid along the river line to support the huge mausoleum buildings. Masons, stonecutters, inlayers, carvers, painters, calligraphers, dome-builders and other artisans were requisitioned from the whole of the empire and also from Central Asia and Iran. While bricks for internal constructions were locally prepared, white marble for external use in veneering work was obtained from Makrana in Rajasthan. Semi-precious stones for inlay ornamentation were brought from distant regions of India, Ceylon and Afghanistan. Red sandstone of different tints was requisitioned from the neighbouring quarries of Sikri, Dholpur, etc. It took 17 years for the monument complex to be completed in 1648.
In all, the Taj Mahal covers an area of 60 bighas, as the terrain gradually sloped from south to north, towards the river, in the form of descending terraces. At the southern point is the forecourt with the main gate in front and tombs of Akbarabadi Begum and Fatehpuri Begum, two other queens of Shah Jahan, on its south-east and south-west corners respectively called Saheli Burj 1 and 2.
On the second terrace is a spacious square garden, with side pavilions. It is divided into four quarters by broad shallow canals of water, with wide walkways and cypress avenues on the sides. The water channels and fountains are fed by overhead water tanks. These four quarters are further divided into the smaller quarters by broad causeways, so that the whole scheme is in a perfect char-bagh.
The main tomb of the Taj is basically square with chamfered corners. The minarets here are detached, facing the chamfered angles (corners) of the main tomb on the main plinth. Red sandstone mosque on the western, and Mehman-Khana on the eastern side of the tomb provides aesthetically a clear colour contrast.
The Taj has some wonderful specimens of polychrome inlay art both in the interior and exterior on the dados, on cenotaphs and on the marble jhajjhari (jali-screen) around them.
Yesterday evening I was driving into London when I came up to a red light, there was a fair amount of traffic so I figured it might be a wait. I saw motion in my peripheral so glanced to my left where I saw 4 men in a red van, they were looking worried and motioning to my wheel, I was worried and wound down my window. Initially I smiled at them, thankful they were warning me of whatever might be wrong with my car, my smile faded rapidly as they all looked at me and, instead, started berating me with verbal sexual abuse. Completely horrendous disgusting things that that said they wanted to do to me. I turned and stared forward trying to wind my window up, I remembered pretty quickly that my window had been broken for a while now and doesn't wind up to the top without help, so I had to leave it, with a rather large gap. For the next 5 minutes I was frozen in shock and fear holding into my steering wheel staring forward willing the light to turn green so I could leave.
I don't think anyone needs to hear the specifics of the things they were saying, in the realm of how they wanted to bend me over this or that and shove things in here or there. I had a deep visceral reaction to there abuse, I was instantly shaking and felt vulnerable and targeted. It all felt so invasive.
Luckily the light turned green and I drove off towards my destination, which fortunately was a restaurant where my family was.
On the drive home a thought more about the incident, it reminded me of the recent leaked video of Presidential candidate Donald Trump. He may have passed it off as locker room banter, or that it was just words, but what his actions and thoughts and voice, what it does it condone this kind of behaviour, that other men will think this is ok. It is not ok.
As I was sat there staring forward holding back tears as they spoke those horrendous words I didn't understand, I didn't understand why they kept talking, why they kept saying more predatory sexual things, how they kept objectifying me when I was so visibly scared and upset. What humans are these?
My incident was minor but had a horribly visceral reaction, more incidents are a lot lot worse, horribly so. On reflection I will come back to how damaging videos like the one of Trump perpetuate this behaviour. If you asked those men after what they were doing, they would just say they were just being a bunch of lads, it was just banter. It should never be passed of as any of these things, as a result you are making someone physically shake, you are making them scared, feel vulnerable and frozen with fear.
This isn't acceptable.
I did post about what happen on Instagram and will say this though, for every completely shit person out there, there is also a thousand amazing people and I can't thank you enough to all those people that commented to show their mutual outrage and to see if I was ok. I am, and you all helped, thank you so much.
finally got photoshop on my laptop for a 30 day trial. I say this every time I upload but I miss flickr so much sometimes and I miss who I used to be x
Washington, Connecticut. Driving home from an errand my left peripheral vision caught these trees with the fog behind them and it took my brain about 1/4 mile to register that I should stop, get out of the truck, set up the camera on tripod and take a picture. Some days wanting to get home and warm up by the fire really gets in the way of photography, other days photography gets in the way of getting home. When these two forces hit simultaneously one is frozen and it's interesting to see what tips it one way or the other.

If you look closely at the reflection in the eye, it's actually of the racetrack.
One of the most rewarding joys of landscape photography for me is way it catalyzes calming, almost elementally humbling feelings. When in such locations as this shot, (Flambrough head at low tide) I feel profoundly immersed in nature and genuinely emotionally centred. It just feels ‘so right’ on many different levels. (Sorry to sound a bit like a new age eco warier so early in this post, but even the most emotionally hard street photographers amongst you, should just try at least once placing yourself in such environments to see how it feels...)
Anyway, not only does this environment help me feel calm and centred, but the very act of photographing it, offers the added caveat of immense exhilaration. Putting oneself into this dynamic environment, at dusk, at the very edge of acceptable safety, dodging waves, wading just that bit too far out and second guessing the incoming tide, has the stimulating ability to sharpen the mind. Let’s not forget dealing with the anxious feelings knowing that you’re mobile is out of signal and any form of human insurance left hours ago. Let’s not stress either, about the long slippery walk over wet seaweed encrusted rocks back to the car in the dark, (unless of course you slip within the tidal range), but your most probably going to end up alive in the morning.
But just reflecting for a moment, I’m sure that I wouldn’t make the considerably arduous effort and experience the feelings of excitement and anxiety associated with pushing oneself to the edge of acceptable risk, if I wasn’t doing it for a photographic reason. In part, it’s the very risk taking itself that inspires the deep humbling feelings of connectivity with the natural surroundings. I wouldn’t be doing this, (or experiencing what I am) if it were not for the fact that I am attempting to record the feeling photographically. Yes I could connect with my inner calma and tune my sharks in other ways and do yoga overlooking a setting sun to really connect with the oneness of nature, (believe me I’ve seen people doing it) but I wouldn’t be pushing myself towards feeling this unique type of exhilaration. It would be a little strange to be there at dusk sometimes a little too deep in choppy seas, really observing the natural rhythms of nature without having a reason for looking. The desire to seek out this in our environment, even with camera gear strapped to my back, has actually helped catalyse a deeper feel a oneness with the environment. It’s as close to a meditation experience I can admit to here in public. Anyway as I said, there are many reasons for my photographic obsessing, but in part anyway this exhilaration is often overlooked as one of those justifications.
Now turning to this shot in greater depth, the range of subtle colours generated in this location amazed me. Flambrough is fundamentally white chalk cliffs and this does wondrous things to the reflected and refracted light, especially in the water. Light just bounces around, even when there isn’t much around, creating much more depth and range of colours. With this particular evening the sunset didn’t really materialise, (shame as the previous evening there was a speculator dramatic light show but for the sake of my marriage, I only saw it through my peripheral vision) but in a gritted teeth mature way, I’m kind of glad that I ended up here on this evening. It offered me the opportunity to appreciate the subtler more calming experiences. Something that as I get older I’m enjoying much more, who knows I may even put the camera on timed release next time and adopt the lotus position to record my tree hugging development.
From my analog archives, the Sigma 3 was being used for real time data collection and analysis in life sciences R&D. It had 64k of IRON core memory. It was taken in September of 1978 in Skokie, illinois. Initially the Sigma line of scientific real time computers was used to collect and analyze telemetry data from early US satellites. On the far left of the frame, the papers are taped to a Xerox 530 which we used as the development environment.
There's a story here. One of the values of visiting the same location very often is that the mind -- the subconscious perhaps -- makes a map of sorts. When one sees something which is new to the area, out of place, disjointed, the mind notices.
Walking through the upper woods, mostly watching the tree tops for the Great Horned Owl, my peripheral vision noted something out of place...at a distance. I did a bit of a double take, looked through the lens, and realized I was seeing a Red-Tail sitting on a log. I shot some frames; the motor drive sound spooked it, and I kept shooting as it lifted off. I was SO fortunate.
This is, I'm reliably told, a juvenile Krider's (pale morph) Red-Tailed Hawk.
You can see the hawk bump on the log which peripheral vision noticed in the distance, in the top comment box photo below.

encompassed by peripheral fear
wondering if you will shed a tear

SpO2 Defined as Peripheral Oxygen Saturation
incenter.medical.philips.com/doclib/enc/fetch/586262/5864...
Introduction
The body's need for oxygen is certain. Its availability at a tissue level is some- times in doubt. Blood gas measurements provide critical information regard- ing oxygenation, ventilation, and acid-base status.
However, these measurements only provide a snapshot of the patient's condition taken at the time that the blood sample was drawn. It is well known that oxygenation can change very quickly. In the absence of continuous oxygenation monitoring, these changes may go undetected until it is too late.
Pulse oximeters measure blood oxygen saturation noninvasively and continuously.
What is SpO2?
A blood-oxygen saturation reading indicates the percentage of hemoglobin molecules in the arterial blood which are saturated with oxygen. The reading may be referred to as SaO2. Readings vary from 0 to 100%. Normal readings in a healthy adult, however, range from 94% to 100%.
The term SpO2 means the SaO2 measurement determined by pulse oximetry. As explained in the section "Considerations When Using Pulse Oximetry," under some circumstances pulse oximetry gives different readings, and the use of a different term indicates this.
How Does Pulse Oximetry Work?
Within the Sp02 sensor, light emitting diodes shine red and infrared light through the tissue. Most sensors work on extremities such as a finger, toe or ear. The blood, tissue and bone at the application site absorb much of the light. However, some light passes through the extremity. A light-sensitive detector opposite the light source receives it.
SpO2 Sensors
Most sensors work on extremities such as a finger, toe or ear. The sensor measures the amount of red and infrared light received by the detector and calcu- lates the amount absorbed. Much of it is absorbed by tissue, bone and venous blood, but these amounts do not change dramatically over short periods of time.
The amount of arterial blood does change over short periods of time due to pulsation (although there is some constant level of arterial blood). Because the arterial blood is usually the only light absorbing component which is changing over short periods of time, it can be isolated from the other compo- cents.

Oxygen Saturation As Presented in Wikipedia:
en.wikipedia.org/wiki/Oxygen_saturation_(medicine)
Oxygen saturation is a term referring to the fraction of oxygen-saturated hemoglobin relative to total hemoglobin (unsaturated + saturated) in the blood. The human body requires and regulates a very precise and specific balance of oxygen in the blood. Normal blood oxygen levels in humans are considered 95-100 percent. If the level is below 90 percent, it is considered low resulting in hypoxemia.[1] Blood oxygen levels below 80 percent may compromise organ function, such as the brain and heart, and should be promptly addressed. Continued low oxygen levels may lead to respiratory or cardiac arrest. Oxygen therapy may be used to assist in raising blood oxygen levels. Oxygenation occurs when oxygen molecules (O
2) enter the tissues of the body. For example, blood is oxygenated in the lungs, where oxygen molecules travel from the air and into the blood. Oxygenation is commonly used to refer to medical oxygen saturation.

Definition[edit]
In medicine, oxygen saturation (SO2), commonly referred to as "sats," measures the percentage of hemoglobin binding sites in the bloodstream occupied by oxygen.[2] At low partial pressures of oxygen, most hemoglobin is deoxygenated. At around 90% (the value varies according to the clinical context) oxygen saturation increases according to an oxygen-hemoglobin dissociation curve and approaches 100% at partial oxygen pressures of >10 kPa. A pulse oximeter relies on the light absorption characteristics of saturated hemoglobin to give an indication of oxygen saturation.
Physiology
The body maintains a stable level of oxygen saturation for the most part by chemical processes of aerobic metabolism associated with breathing. Using the respiratory system, red blood cells, specifically the hemoglobin, gather oxygen in the lungs and distribute it to the rest of the body. The needs of the body's blood oxygen may fluctuate such as during exercise when more oxygen is required [3] or when living at higher altitudes. A blood cell is said to be "saturated" when carrying a normal amount of oxygen.[4] Both too high and too low levels can have adverse effects on the body.
Measurement[edit]
An SaO2 (arterial oxygen saturation, as determined by an arterial blood gas test[5]) value below 90% causes hypoxemia (which can also be caused by anemia). Hypoxemia due to low SaO2 is indicated by cyanosis. Oxygen saturation can be measured in different tissues:
Venous oxygen saturation (SvO2) is measured to see how much oxygen the body consumes. Under clinical treatment, a SvO2 below 60% indicates that the body is in lack of oxygen, and ischemic diseases occur. This measurement is often used under treatment with a heart-lung machine (extracorporeal circulation), and can give the perfusionist an idea of how much flow the patient needs to stay healthy.
Tissue oxygen saturation (StO2) can be measured by near infrared spectroscopy. Although the measurements are still widely discussed, they give an idea of tissue oxygenation in various conditions.
Peripheral oxygen saturation (SpO2) is an estimation of the oxygen saturation level usually measured with a pulse oximeter device. It can be calculated with pulse oximetry according to the following formula:
SpO2 = HbO2/ (HbO2 + Hb)
Example: Pulse Oximeter
Pulse oximetry is a method used to estimate the percentage of oxygen bound to hemoglobin in the blood. This approximation to SaO2 is designated SpO2 (peripheral oxygen saturation). The pulse oximeter consists of a small device that clips to the body (typically a finger, earlobe or an infants foot) and transfers its readings to a reading meter by wire or wirelessly. The device uses light-emitting diodes in conjunction with a light-sensitive sensor to measure the absorption of red and infrared light in the extremity. The difference in absorption between oxygenated and deoxygenated hemoglobin makes the calculation possible.[5]
Medical significance
Effects of decreased oxygen saturation[6]
SaO2Effect
85% and aboveNo evidence of impairment
65% and lessImpaired mental function on average
55% and lessLoss of consciousness on average
Healthy individuals at sea level usually exhibit oxygen saturation values between 96% and 99%, and should be above 94%. At 1600 meters altitude (about one mile high) oxygen saturation should be above 92%.[7]
An SaO2 (arterial oxygen saturation) value below 90% causes hypoxia (which can also be caused by anemia). Hypoxia due to low SaO2 is indicated by cyanosis, but oxygen saturation does not directly reflect tissue oxygenation. The affinity of hemoglobin to oxygen may impair or enhance oxygen release at the tissue level. Oxygen is more readily released to the tissues (i.e., hemoglobin has a lower affinity for oxygen) when pH is decreased, body temperature is increased, arterial partial pressure of carbon dioxide (PaCO2) is increased, and 2,3-DPG levels (a byproduct of glucose metabolism also found in stored blood products) are increased. When the hemoglobin has greater affinity for oxygen, less is available to the tissues. Conditions such as increased pH, decreased temperature, decreased PaCO2, and decreased 2,3-DPG will increase oxygen binding to the hemoglobin and limit its release to the tissue.[8]
While sitting in my blind watching for Wood Duck activity there was often a lot of peripheral activity that was equally exciting. One day in April a Great Blue Heron came out on what I call my "stage" (my range of visibility) and began hunting. Almost immediately it caught this Catfish and began maneuvering the fish in preparation to swallow it whole. After several minutes the heron finally had the fish in its throat but the catfish got stuck, probably hooked by one of the barbs. The heron gagged a bit and finally coughed the fish back out again, readjusted and then swallowed it in one swift move. I did see Wood Ducks that day, but it was this Great Blue Heron and its catfish sidekick that stole the show. April 18, 2015
I've been hiking Wilcox Pass to look for Bighorn Sheep since 1988, but this was my first time in four years. I hauled out of bed - I mean sleeping bag - early and was on the trail in the dim dark of pre-dawn. No searching was required. I emerged from the trees onto an open ridge and spotted four rams almost immediately. They allowed a close approach and were very relaxed.
When rams reach maturity, their horns can curl tightly enough to block their peripheral vision, so they often "broom" the tips off by rubbing them against rocks.
