Irradiation directly from the sun.
That portion of the electromagnetic spectrum immediately below the visible range and extending into the x-ray frequencies. The longer wavelengths (near-UV or biotic or vital rays) are necessary for the endogenous synthesis of vitamin D and are also called antirachitic rays; the shorter, ionizing wavelengths (far-UV or abiotic or extravital rays) are viricidal, bactericidal, mutagenic, and carcinogenic and are used as disinfectants.

Chemical or physical agents that protect the skin from sunburn and erythema by absorbing or blocking ultraviolet radiation.
A nutritional condition produced by a deficiency of VITAMIN D in the diet, insufficient production of vitamin D in the skin, inadequate absorption of vitamin D from the diet, or abnormal conversion of vitamin D to its bioactive metabolites. It is manifested clinically as RICKETS in children and OSTEOMALACIA in adults. (From Cecil Textbook of Medicine, 19th ed, p1406)
A vitamin that includes both CHOLECALCIFEROLS and ERGOCALCIFEROLS, which have the common effect of preventing or curing RICKETS in animals. It can also be viewed as a hormone since it can be formed in SKIN by action of ULTRAVIOLET RAYS upon the precursors, 7-dehydrocholesterol and ERGOSTEROL, and acts on VITAMIN D RECEPTORS to regulate CALCIUM in opposition to PARATHYROID HORMONE.
Tumors or cancer of the SKIN.

It refers almost exclusively to skin photosensitivity, including sunburn, reactions due to repeated prolonged exposure in the absence of photosensitizing factors, and reactions requiring photosensitizing factors such as photosensitizing agents and certain diseases. With restricted reference to skin tissue, it does not include photosensitivity of the eye to light, as in photophobia or photosensitive epilepsy.
A nonimmunologic, chemically induced type of photosensitivity producing a sometimes vesiculating dermatitis. It results in hyperpigmentation and desquamation of the light-exposed areas of the skin.
Tumors, cancer or other neoplasms produced by exposure to ionizing or non-ionizing radiation.
Divisions of the year according to some regularly recurrent phenomena usually astronomical or climatic. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed)
A malignant skin neoplasm that seldom metastasizes but has potentialities for local invasion and destruction. Clinically it is divided into types: nodular, cicatricial, morphaic, and erythematoid (pagetoid). They develop on hair-bearing skin, most commonly on sun-exposed areas. Approximately 85% are found on the head and neck area and the remaining 15% on the trunk and limbs. (From DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1471)

Dimers found in DNA chains damaged by ULTRAVIOLET RAYS. They consist of two adjacent PYRIMIDINE NUCLEOTIDES, usually THYMINE nucleotides, in which the pyrimidine residues are covalently joined by a cyclobutane ring. These dimers block DNA REPLICATION.
The processes by which organisms utilize organic substances as their nutrient sources. Contrasts with AUTOTROPHIC PROCESSES which make use of simple inorganic substances as the nutrient supply source. Heterotrophs can be either chemoheterotrophs (or chemoorganotrophs) which also require organic substances such as glucose for their primary metabolic energy requirements, or photoheterotrophs (or photoorganotrophs) which derive their primary energy requirements from light. Depending on environmental conditions some organisms can switch between different nutritional modes (AUTOTROPHY; heterotrophy; chemotrophy; or PHOTOTROPHY) to utilize different sources to meet their nutrients and energy requirements.
The group of celestial bodies, including the EARTH, orbiting around and gravitationally bound by the sun. It includes eight planets, one minor planet, and 34 natural satellites, more than 1,000 observed comets, and thousands of lesser bodies known as MINOR PLANETS (asteroids) and METEOROIDS. (From Academic American Encyclopedia, 1983)
The synthesis by organisms of organic chemical compounds, especially carbohydrates, from carbon dioxide using energy obtained from light rather than from the oxidation of chemical compounds. Photosynthesis comprises two separate processes: the light reactions and the dark reactions. In higher plants; GREEN ALGAE; and CYANOBACTERIA; NADPH and ATP formed by the light reactions drive the dark reactions which result in the fixation of carbon dioxide. (from Oxford Dictionary of Biochemistry and Molecular Biology, 2001)

Vitamin D status in different subgroups of British Asians. (1/1331)

To assess the effect of religious dietary practices and social customs on the vitamin D status of Asian immigrants, we kept records of the dietary intake and time spent out of doors of 81 Ugandan Asian men, women, and girls (9-19 years old). Sera were analysed for 25-hydroxycholecalciferol (25-OHD3), and 28% of the subjects were found to have levels below the lower limit of normal. The (vegetarian) Hindus had the lowest dietary intakes, least time out of doors, and lowest serum 25-OHD3. The Goan (Roman Catholic) Asians, despite more pigmentation, had 25-OHD3 levels similar to those found among indigenous British people and had the most satisfactory vitamin D intakes. Among Asians, whose exposure to sunlight may be limited, dietary vitamin D becomes the major determinant of serum 25-OHD3.  (+info)

Histologic analysis of photochemical lesions produced in rhesus retina by short-wave-length light. (2/1331)

The photopathology of retinal lesions produced by extended exposure (1000 sec) to low corneal power levels (62 microW) of blue light (441 nm) was investigated by light microscopy in 20 rhesus eyes over an interval ranging from 1 hr to 90 days after exposure. Results indicate a nonthermal type of photochemical lesion originating in the retinal pigment epithelium and leading to a histological response with hypopigmentation which requires 48 hr to appear. This type of lesion helps to explain solar retinitis and eclipse blindness and has significance for aging and degenerative changes in the retina.  (+info)

Absorption of solar radiation by an ellipsoid sensor simulated the human body. (3/1331)

Assessment of heat gain in man caused by solar radiation is one of the most important problems in research of the human heat balance outdoors. The purpose of the present study was to investigate a new method for estimation of solar heat income. Absorption of short wave radiation (direct, diffuse and reflected) was measured with an ellipsoid sensor representing a simple, physical model of man. Measurements were performed in climatic chamber with the use of an iodide CSI solar lamp. The absorbed quantity of solar radiation varied as a result of sun altitude as well as of a colour and insulation of fabric covering the ellipsoid sensor. The new coefficients derived from our investigations for estimating doses of absorbed solar radiation should be applicable for a standing man. They correlate better with mean skin temperature observed on subjects outdoor than previous results obtained based on a cylinder as an analogue model of man. The ellipsoid sensor covered by a black fabric absorbed about 6 times more of solar radiation than when covered by a white textile.  (+info)

Merkel cell carcinoma and melanoma: etiological similarities and differences. (4/1331)

Merkel cell carcinoma (MCC) of the skin and cutaneous malignant melanoma can now be compared epidemiologically through the use of population-based data not previously available for MCC. The results may provide new clues to etiology. In this study, United States data covered by the Surveillance, Epidemiology, and End Results (SEER) Program were from nine areas of the United States (approximately 10% of the population). In 1986-1994, 425 cases of MCC were registered. The annual age-adjusted incidence per 100,000 of MCC was 0.23 for whites and 0.01 for blacks; among whites, the ratio of melanoma to MCC was approximately 65 to 1. Only 5% of MCC occurred before age 50, unlike the lifelong risk of nodular and superficial spreading melanoma. Regional incidence rates of both cancers increased similarly with increasing sun exposure as measured by the UVB solar index. The most sun-exposed anatomical site, the face, was the location of 36% of MCC but only 14% of melanoma. Both cancers increased in frequency and aggressiveness after immunosuppression and organ transplantation (36 cases from the Cincinnati Transplant Tumor registry and 12 from published case reports) and after B-cell neoplasia (5 cases in this study; 13 from case series in the literature). The SEER data contained reports of six patients with both types of cancer; 5 melanomas before the diagnosis of MCC and 1 after diagnosis. MCC and melanoma are similarly related to sun exposure and immunosuppression, but they differ markedly from one another in their distributions by age, race, and anatomical site, especially the face.  (+info)

p53 mutations in human cutaneous melanoma correlate with sun exposure but are not always involved in melanomagenesis. (5/1331)

In melanoma, the relationship between sun exposure and the origin of mutations in either the N-ras oncogene or the p53 tumour-suppressor gene is not as clear as in other types of skin cancer. We have previously shown that mutations in the N-ras gene occur more frequently in melanomas originating from sun-exposed body sites, indicating that these mutations are UV induced. To investigate whether sun exposure also affects p53 in melanoma, we analysed 81 melanoma specimens for mutations in the p53 gene. The mutation frequency is higher than thus far reported: 17 specimens (21%) harbour one or more p53 mutations. Strikingly, 17 out of 22 mutations in p53 are of the C:G to TA or CC:GG to TT:AA transitional type, strongly suggesting an aetiology involving UV exposure. Interestingly, the p53 mutation frequency in metastases was much lower than in primary tumours. In the case of metastases, a role for sun exposure was indicated by the finding that the mutations are present exclusively in skin metastases and not in internal metastases. Together with a relatively frequent occurrence of silent third-base pair mutations in primary melanomas, this indicates that the p53 mutations, at least in these tumours, have not contributed to melanomagenesis and may have originated after establishment of the primary tumour.  (+info)

In situ repair of cyclobutane pyrimidine dimers and 6-4 photoproducts in human skin exposed to solar simulating radiation. (6/1331)

DNA repair is crucial to the integrity of the human genome. The ultraviolet radiation portion of solar radiation is responsible for the rising incidence of skin cancer, one of the most common types of cancer in humans. We applied a recently developed 32P-postlabeling technique to measure the in situ DNA repair efficiency of solar-simulated radiation induced cyclobutane pyrimidine dimers and 6-4 photoproducts in the skin of nine healthy volunteers with skin type II. Our results show about 6-fold interindividual variations in the level of DNA damage after exposure to an equal biologic dose - 2 minimal erythema doses. The kinetics of DNA repair indicated a base sequence dependence of the repair process. The DNA repair efficiency showed a 20-fold difference in volunteers. An age-related decrease of DNA repair capacity was observed; however, the data are limited due to a small number of subjects and a narrow age range. The variable response in DNA damage levels and individual differences in DNA repair efficiency suggest a susceptible subgroup of people probably with a higher skin cancer risk.  (+info)

Is sunlight an aetiological agent in the genesis of retinoblastoma? (7/1331)

The incidence of unilateral, but not bilateral, retinoblastoma in human populations at different geographical locations increases significantly with ambient erythemal dose of ultraviolet B radiation from sunlight. This supports the hypothesis that sunlight plays a role in retinoblastoma formation.  (+info)

Ineffective vitamin D synthesis in cats is reversed by an inhibitor of 7-dehydrocholestrol-delta7-reductase. (8/1331)

Changes in plasma 25-hydroxyvitamin D (25-OHD) were used as an index of vitamin D status of cats. Plasma 25-OHD concentration of kittens given a purified vitamin D-free diet and exposed to direct summer sun for 15 h/wk declined at a similar rate as kittens given the same diet kept indoors. Similarly, plasma 25-OHD of kittens exposed to ultraviolet (UV) lamps declined at a similar rate as kittens not exposed, and these kittens developed clinical signs of vitamin D deficiency. Eight weaned kittens were given the vitamin D-free purified diet until their plasma concentrations of 25-OHD were < 5 nmol/L. They then had the hair on their backs clipped at weekly intervals and were paired on the basis of skin color and exposed to UV light for 2 h/d. One member of each pair was given an inhibitor of 7-dehydrocholesterol (5, 7-cholestradien-3beta-ol)-delta7-reductase (EC in the diet. Cats receiving the inhibitor had a progressive increase in 25-OHD concentration of plasma with time to 91 +/- 22 nmol/L (mean +/- SEM), whereas cats not receiving the inhibitor had plasma 25-OHD concentrations that were not detectable (P < 0.001). Biopsy samples of skin from cats receiving the inhibitor had more than five times the concentration of 7-dehydrocholesterol (P < 0.001) than the skin of control cats. Low concentration of 7-dehydrocholesterol (presumably due to high activity of the reductase) in the skin of cats is the major impediment to effective vitamin D synthesis. Analysis of wild caught potential prey of cats indicated that these animals could supply adequate vitamin D to meet the requirement of growing kittens.  (+info)

In 1929, architect Richard Neutra built the famous Health House in the Hollywood Hills of Los Angeles. His brief was to design a home that strengthened the health and well-being of its owner, Dr. Philip Lovell. The Health House provided Dr. Lovell with access to plenty of sunlight and fresh air. Such thinking informed the work of other architects of the period, such as Le Corbusier. In his influential manifesto The Athens Charter, Le Corbusier argued bringing in the sun was the architects new and most urgent duty.. However, many years before Neutra and Le Corbusier - and before the effects of sunlight exposure were investigated scientifically - Florence Nightingale had already identified sunlight as key to promoting health in hospitals. She wrote:. Direct sunlight, not only daylight, is necessary for speedy recovery, except, perhaps in certain ophthalmic and a small number of other cases.. Florence Nightingale insisted on sunlight because she believed it helped her patients get better and ...

This is the first study to establish a link between the season of initiating interferon/ribavirin-based therapy for CHC and viral response to treatment. Our results suggest that viral response to treatment was influenced by the hours of sunlight, and by inference, sunlight exposure, a surrogate marker of vitamin D levels.. The most striking finding in our cohort of patients from different latitudes was that a different viral response was observed according to the season of initiating peginterferon/ribavirin-based treatment. In fact, patients starting treatment during the season with the highest daily hours of sunlight, according to the State Meterological Agency,17 showed the highest rate of RVR. We believe our findings are coherent for different reasons. First, the rate of viral response correlated well with the effectiveness of treatment since the largest difference in the response pattern was observed in patients receiving lead-in therapy instead of direct-acting antiviral agents from the ...

Objectives Preventable risk factors for prostate cancer are poorly understood; sun exposure is a possible protective factor. The goal of this study was to investigate prostate cancer risk in outdoor workers, a population with high sun exposure. Methods Prostate cancer cases and controls from a large study (conducted between 1994 and 1997) were used for this analysis. A job exposure matrix ( JEM) was used to assign solar ultraviolet radiation (UVR) at work as moderate (2 to ,6 hours outside/day) or high (≥6 hours). Average daily satellite UV-B measures were linked to the latitude/longitude of the residences of each participant. Several other exposure metrics were also examined, including ever/never exposed and standard erythemal dose by years (SED×years). Logistic regression was used to evaluate the association between solar UVR exposure and the odds of prostate cancer. Results A total of 1638 cases and 1697 controls were included. Men of Indian and Asian descent had reduced odds of prostate ...
Outdoor solar lights use the energy provided by sunlight to charge preinstalled batteries. Most have sensors that will turn the light on automatically when the sun begins to go down and off when the sun comes up. Some solar lights are mounted on ground spikes or stakes, and others are simply placed on the ground.
Many outdoor workers are exposed to dangerous levels of ultraviolet radiation, sometimes over many years. If not detected early enough, sun damage can lead to fatal cancers. The problem in Victoria is very serious. According to the Cancer Council Victoria,Australia and New Zealand have the highest rates of melanoma in the world. More than 10,000 people are diagnosed with melanoma in Australia every year. Melanoma of the skin is the fourth most common cancer in both men and women. It accounts for 10 per cent of all cancer diagnoses. One in 19 Australians will be diagnosed with melanoma before age 85, and it is the most common type of cancer in young Australians aged 15 to 44 (20 per cent of all cases). The National Hazard Exposure Worker Surveillance: Exposure to direct sunlight and the provision of sun exposure controls in Australian workplaces report undertaken by Safe Work Australia in 2010 focused on the exposure of Australian workers to direct sunlight and the control measures that were ...
Not only does adequate sunlight exposure result in the production of vitamin D, a hormone-like substance that regulates over 2,000 genes in the human body -- and as a result prevents or ameliorates hundreds of vitamin D deficiency associated health conditions -- but sunlight exposure itself has a unique set of health benefits not reducible to simply vitamin D production alone. One of the more interesting studies performed on sunlight exposure, based on data gathered from over 100 countries and published earlier this year in the journal Anticancer Research, showed that there was a strong inverse correlations with solar UVB for 15 types of cancer, with weaker, though still significant evidence for the protective role of sunlight in 9 other cancers. Here are some additional benefits of sunlight exposure: ...
Objective: Although bipolar disorder has high heritability, the onset occurs during several decades of life, suggesting that social and environmental factors may have considerable influence on disease onset. This study examined the association between the age of onset and sunlight at the location of onset. Method: Data were obtained from 2414 patients with a diagnosis of bipolar I disorder, according to DSM-IV criteria. Data were collected at 24 sites in 13 countries spanning latitudes 6.3 to 63.4 degrees from the equator, including data from both hemispheres. The age of onset and location of onset were obtained retrospectively, from patient records and/or direct interviews. Solar insolation data, or the amount of electromagnetic energy striking the surface of the earth, were obtained from the NASA Surface Meteorology and Solar Energy (SSE) database for each location of onset. Results: The larger the maximum monthly increase in solar insolation at the location of onset, the younger the age of ...

The image above shows the umbra and penumbra as commonly illustrated in astronomy books. The sun is not a point source of light but a sphere much larger than the Earth. Rays of light depart in all directions from any point on its surface, to the effect that there is a conical volume of space behind the Earth where the rays cannot reach, or, in other words, from where an observer can see no part of the apparent disk of the sun. That conical volume of space is the umbra , simply meaning shadow in Latin. Around it there is an area from which an observer can see part of the suns disk, so that area receives some direct sunlight, but not full sunlight: the penumbra (nearly shadow). Everywhere else receives full sunlight. The length of the umbra cone depends on the diameters of the Sun and the Earth and the distance between them, as a few minutes experimenting with some sketches will show you ...
A novel class of photocatalytic coating capable of degrading bacterial and chemical contaminants in the presence of visible sunlight wavelengths was produced by depositing a stable photocatalytic TiO2 film on the internal lumen of glass bottles via a sol gel method. This coating was prepared in either undoped form or doped with nitrogen and/or copper to produce visible light-active TiO2 films which were annealed at 600 °C and were characterized by Raman, UV-Vis, and X-ray photoelectron spectroscopy. The presence of doped and undoped TiO2 films was found to accelerate the degradation of methylene blue in the presence of natural sunlight, while copper-doped TiO2 films were found to accelerate bacterial inactivation (of E. coli and E. faecalis) in the presence of natural sunlight.
Where c is the atmospheric extinction and m is the relative optical airmass . The atmospheric extinction brings the number of lux down to around 100,000.. The total amount of energy received from the Sun at the zenith depends on the distance to the Sun and thus on the time of year. It is about 3.3% higher than average in January and 3.3% lower in July (see below). If the extraterrestrial solar radiation is 1367 watts per square meter (the value when the Earth-Sun distance is 1 astronomical unit ), then the direct sunlight at Earths surface when the Sun is at the zenith is about 1050 W / m 2 , but the total amount (direct and indirect from the atmosphere) hitting the ground is around 1120 W / m 2 . [5] In terms of energy, sunlight at Earths surface is around 52 to 55 percent infrared (above 700 nm)), 42 to 43 percent visible (400 to 700 nm), and 3 to 5 percent ultraviolet (below 400 nm).

By Marc Sorenson, Sunlight Institute. In a scientific paper, Dr. MS Razzaque shows that there may be some downsides to vitamin D supplementation, including cardiovascular events and beyond. He also states that since hypovitaminosis D status usually reflects reduced sunlight exposure, the obvious primary replacement should be safe sunlight exposure, and not exogenous supplements.. The paper specifically mentions that avoiding sunlight exposure may influence the initiation and progression of different types of tumors [cancer], high blood pressure, type 1 diabetes and multiple sclerosis. It also points out that there may be some deleterious consequences of vitamin D supplementation, although in my opinion, the dosage would need to by quite high.. As I have indicated in many of my posts on the Sunlight Institute site, sun exposure is the most natural way to obtain vitamin D, and it has no toxicity, since it is self-regulated.. What wasnt mentioned was the production of health-promoting ...
News The latest news about sun exposure, Vitamin D, the benefits of sunlight, and general sun health from the Sunlight Institute.
Chances are, you remember some of the basics from high school science classes. Plants require a mix of sunlight, soil, and water to grow. They pull nutrients from the soil and convert sunlight into usable energy. This energy sustains the plants metabolism the same way food sustains our metabolisms.. But plants are extremely diverse, and what works for one may not work for another. Different species need different ratios of sun to shade and water. Too much sunlight can scorch a temperate species, while too much water can drown a desert species.. Most gardens need around eight hours of direct sunlight per day. If you live in an area thats often overcast, thats okay! As long as youre planting native species, the plants should be able to thrive regardless.. Where plants have trouble is when an area is too shady or too sunny. Some species naturally grow in the shadow of tall trees and shrubs, shielded from most direct sunlight. Others require extensive daily sun exposure to avoid ...
TY - CHAP. T1 - Decontamination of water by solar irradiation. AU - Malato, Sixto. AU - Maldonado, Manuel I.. AU - Fernández, Pilar. AU - Oller, Isabel. AU - Polo, Inmaculada. PY - 2014/1/1. Y1 - 2014/1/1. N2 - Humankind has been changing, contaminating, and polluting their environment since the Paleolithic era. This first type of pollution was air pollution through the use of fire (Spengler and Sexton, 1983). Later, in the Bronze Age and Iron Age, the forging of metals produced significant air and soil pollution as can be seen in glacial core samples in Greenland (Honget al., 1996). As early as the 9th century, Arab and Persian scientists have written about pollution and waste handlings (Gari, 2002). The industrial revolution in the 19th century led to the environmental pollution, as we know it today with its new industries and the enormous consumption of coal and oil, which lead to air pollution and the discharge of chemicals and industrial wastes into waterways (streams and rivers). After ...

The MoO3 coated ZnO photocatalysts were synthesized for the optimum harvesting of the absorbed ultraviolet sunlight photons by initially permeating Mo6+ ions at the surface of pre-synthesized ZnO and finally transformed to MoO3 by thermal treatment in the air. The absorption spectra of the synthesized powders revealed the extension of the absorption edge in the visible region whereas, the photoluminescence spectroscopy established the supporting role of the MoO3 coating in gradually plummeting the excitons recombination. The growth of additional peaks in Raman as well as X-ray photoelectron spectra and the appearance of the corresponding low-intensity reflection substantiated the surface prevalence of MoO3. The absence of the individual particles of MoO3 in FESEM and the verification of coated layer by HRTEM images validated the authenticity of the adopted synthetic route. The electrochemical evaluation of the synthesized powders under illumination revealed the complete elimination of ...
One of the most common causes of a plant struggling in the garden is not enough, or too much, sunlight. It?s important to know how the sunlight changes over the course of the spring and summer. As trees leaf out and the suns angle changes, what was once a full sun area in spring may be part shade by midsummer.. A new tool can help you determine the amount of sunlight that different areas of your yard are receiving. The SunCalc sunlight calculator is a battery-powered tool that records the amount of sunlight over a 12-hour period. The photo-receptive diode registers how much sunlight has accumulated and signals whether the area is in full or part sun, part shade or full shade. Full sun is defined as 6 or more hours of direct sunlight. Part sun is defined as 4 to 6 hours, part shade is 1-1/2 to 4 hours, and full shade is less than 1-1/2 hours. SunCalc works even on cloudy days. If used over a number of months, it can give a good estimation of the sun exposure in various gardens and help you ...
The following is a list of cities by sunshine duration. Sunshine duration is a climatological indicator, measuring duration of sunshine in given period (usually, a day or a year) for a given location on Earth, typically expressed as an averaged value over several years. It is a general indicator of cloudiness of a location, and thus differs from insolation, which measures the total energy delivered by sunlight over a given period. Sunshine duration is usually expressed in hours per year, or in (average) hours per day. The first measure indicates the general sunniness of a location compared with other places, while the latter allows for comparison of sunshine in various seasons in the same location. Another often-used measure is percentage ratio of recorded bright sunshine duration and daylight duration in the observed period. An important use of sunshine duration data is to characterize the climate of sites, especially of health resorts. This also takes into account the psychological effect of ...
Sunlight is an additional source of vitamin D. It is important as dietary sources of vitamin D are few. Ideally we should get 90% of our daily vitamin D requirement from sunlight. UV rays in sunlight convert a type of cholesterol found in the skin to vitamin D. Modern lifestyle has limited our exposure to the sun. There are many variables that affect the ability of the skin to produce vitamin D. As a result it is difficult to recommend how much sunlight is enough. Most authorities recommend between 5 to 30 minutes of sun exposure to your unprotected face, arms, legs or back between 11 am and 3 pm two to three times a week. Early morning or late evening sunlight does not work as UV rays are not able to penetrate the atmosphere. Ability to produce vitamin D also depends on the colour of the skin. Fair skin people need less sunlight than darker ones in whom melanin (skin pigment) restricts entry to UV rays. Exposure to sunlight should be direct as UV rays are restricted by glass (window panes) and ...
Sunlight is recognized as one of the most important environmental factors that influence human health. There is strong evidence in the scientific literature that adequate exposure to sunlight is associated with many physical and mental health benefits, including reduced overall mortality, prevention of many deadly forms of cancer, as well as a number of metabolic, cardiovascular, autoimmune, infectious and neuropsychatric diseases. Vitamin D deficiency, which is mainly due to insufficient exposure to sunlight, is now one of the most common medical conditions, estimated to affect more than a billion people worldwide. Health professionals, patients and the general public should receive more evidence-based information about the many health benefits of sunlight, and how to use it in prevention and treatment of disease.. ...

The Giotto and Vega missions gave planetary scientists their first view of Halleys surface and structure. Like all comets, as Halley nears the Sun, its volatile compounds (those with low boiling points, such as water, carbon monoxide, carbon dioxide and other ices) begin to sublime from the surface of its nucleus.[49] This causes the comet to develop a coma, or atmosphere, up to 100,000 km across.[3] Evaporation of this dirty ice releases dust particles, which travel with the gas away from the nucleus. Gas molecules in the coma absorb solar light and then re-radiate it at different wavelengths, a phenomenon known as fluorescence, whereas dust particles scatter the solar light. Both processes are responsible for making the coma visible.[13] As a fraction of the gas molecules in the coma are ionized by the solar ultraviolet radiation,[13] pressure from the solar wind, a stream of charged particles emitted by the Sun, pulls the comas ions out into a long tail, which may extend more than 100 ...
We have shown that anthropogenic forcings do not polynomially cointegrate with global temperature and solar irradiance. Therefore, data for 1880-2007 do not support the anthropogenic interpretation of global warming during this period. This key result is shown graphically in Fig. 3 where the vertical axis measures the component of global temperature that is unexplained by solar irradiance according to our estimates. In panel a the horizontal axis measures the anomaly in the anthropogenic trend when the latter is derived from forcings of carbon dioxide, methane and nitrous oxide. In panel b the horizontal axis measures this anthropogenic anomaly when apart from these greenhouse gas forcings, it includes tropospheric aerosols and black carbon. Panels a and b both show that there is no relationship between temperature and the anthropogenic anomaly, once the warming effect of solar irradiance is taken into consideration. ...
A combination of sensor calibration error and uncertainty in the solar irradiance can cause very large errors in the computations of the water radiance contribution to the Coastal Zone Color Scanner (CZCS)-measured radiances. This is especially true when the atmospheric correction algorithm is applied in a horizontally inhomogeneous atmosphere. These possible errors can be considerably reduced through spectral measurements of the aerosol optical thickness and upwelled subsurface radiances coincident with a CZCS overpass on a very clear day. For future instruments it is suggested that provision be made for the sensor to view solar irradiance in diffuse reflection. The analysis presented shows that with such a system the error is reduced to a level even below that which would be applicable if the solar irradiance were known precisely.. © 1981 Optical Society of America.

A small excerpt from the Scientific Overview:. There is a lot of confusion caused by different public health messages that are often one-sided and focus mainly on the adverse effects while completely neglecting any health benefits of moderate and responsible exposure to UV radiation. Actually, many scientists agree, that if practiced in moderation and especially avoiding sunburn, the health benefits far outweigh the adverse effects! Furthermore, in a professional studio, sunbeds provide the advantage of being in a controlled environment in comparison to sunlight exposure. An often overlooked fact is also, that the sun and sunbeds provide other health benefits besides the mainly mentioned vitamin D synthesis. Exposure to UV radiation is also releasing nitric oxide in the skin which has a vasodilative effect on the blood vessels and therefore decreases hypertension and the risk for other cardiovascular diseases. Other mediators include serotonin, beta-endorphin, among others, which contribute to ...
First of all, babies rarely need vitamin D supplements. The babies who do need these supplements need them due to a lack of sufficient sunlight. Factors that put your breastfed baby at risk for vitamin D deficiency (rickets) are: • Baby has very little exposure to sunlight. For example: if you live in a far northern latitude, if you live in an urban area where tall buildings and pollution block sunlight, if baby is always completely covered and kept out of the sun, if baby is always inside during the day, or if you always apply high-SPF sunscreen. • Both mother and baby have darker skin and thus require more sun exposure to generate an adequate amount of vitamin D. Again, this is a not enough sunlight issue - the darker your skin pigmentation, the greater the amount of sun exposure needed. There is not much information available on how much more sunlight is needed if you have medium or darker toned skin. See the section below regarding amount of sunlight needed. • Mother is deficient in ...

The effect of three moisture levels and three shade regimes on the growth of D x P ex Kusi oil palm seedlings was investigated at the Oil Palm Research Institute, Kusi between July 1998 and February 2000 in a factorial experiment laid out in randomized complete block design with four replications. The moisture treatments investigated were W1 (50-60 % field capacity), W2 (65-75 % field capacity) and W3 (80-90 % field capacity). The shade treatments investigated were S1 (0 % shade), S2 (50 % shade) and S3 (75 % shade). Data was collected on leaf number per plant, plant height, butt circumference and leaf area as well as dry weight of plant parts and total dry matter. There were significant effects due to shade and shade x moisture interactions on seedling growth. Seedlings under 50% shade (50% full sunlight) in combination with low moisture supply (50-60% field capacity) were comparable in growth to those under 0% shade (100% full sunlight) with high moisture supply (80-90% field capacity). During ...

Incidental Sun Exposure. This is the kind of sun exposure that you are barely aware of, which accumulates over the years from relatively brief everyday activities. For example, individuals are exposed to the sun when walking dogs, waiting for the bus, or walking to and from the car. Everyday incidental exposure adds up and can seriously damage the skin over time.. Cumulative, incidental sun exposure is linked to squamous cell carcinoma (SCC), the second most common skin cancer. An estimated 700,000 cases are diagnosed each year in the US, resulting in approximately 2,500 deaths.. Incidental sun exposure also contributes to basal cell carcinoma. Almost all basal cell carcinomas occur on parts of the body subject to chronic sun exposure - especially the face, ears, neck, scalp, shoulders, and back. BCCs are rarely fatal, but can be highly disfiguring if allowed to grow.. Protect Yourself. The Skin Cancer Foundation recommends that everyone develop a year-round sun protection regimen to reduce the ...
The reason is that you have sunburned eyes. The UV and UVB in the sunlight not only pose great danger to our skin and eventually cause skin cancer, but also lead to sunburned eyes. To protect the eyes, the lenses of adults will absorb a specific amount of UV radiation and near-UV. But being exposed to sunlight or strong glare for too long will break the natural defense. So your eyes will have burning or gritty sensation. Blurred vision or snow blindness may also happen to you. You will not feel uncomfortable when the sunburn happens to you. Instead, you will have the feeling several hours later. After being burned, your eyes will recover in a week or more on their own. However, if your eyes get burned repeatedly, you are prone to have scar tissue in eyes and cataracts. For the sake of your eyes, wear a pair of sunglasses next time when you are in the sunlight.

The first proposal to connect Birkenhead and Liverpool by a rail tunnel was made in 1864 by the Liverpool and Birkenhead Railway Company. The bill received the support of the chairman of the Mersey Docks and Harbour Board and of John Laird, the Member of Parliament for Birkenhead at the time, although ultimately it was unsuccessful due to strong opposition from the LNWR.[44] A second tunnel proposal was made in 1865 by Sir Charles Fox who planned to build a single track pneumatic railway under the Mersey between the two settlements. The Mersey Railway Act was passed in 1866 although the project was hindered with knowledge of engineering difficulties and limitations with pneumatic railways in other parts of the country.[45][46] On 22 December 1869, Fox held a meeting with Liverpool businessmen and merchants where it was decided that the pneumatic single track railway would be substituted with a conventional steam double track line.

The common grackle forages on the ground, in shallow water or in shrubs; it will steal food from other birds. It is omnivorous, eating insects, minnows, frogs, eggs, berries, seeds, grain and even small birds and mice. Grackles at outdoor eating areas often wait eagerly until someone drops some food. They will rush forward and try to grab it, often snatching food out of the beak of another bird. Grackles prefer to eat from the ground at bird feeders, making scattered seed an excellent choice of food for them. In shopping centers, grackles can be regularly seen foraging for bugs, especially after a lawn trimming.. Along with some other species of grackles, the common grackle is known to practice "anting", rubbing insects on its feathers possibly to apply liquids such as formic acid secreted by the insects..
