  Title Overnight measurements of the sky brightness as a method for assessing the cloudiness Type Journal Article
  Year 2019 Publication Photonics Letters of Poland Abbreviated Journal Photon.Lett.PL  
  Volume 11 Issue 3 Pages 72  
  Keywords Skyglow; Remote Sensing  
  Abstract Determining the state of cloudiness at night is always a problem, especially at low levels of light pollution. This paper presents an innovative method of assessing the cloudiness of the night sky solely on the basis of all-night measurements of the brightness of the sky using generally available SQM meters. Using the numerical method of calculating the discrete derivative of overnight brightness of the night sky from time it is possible not only to distinguish a cloudless sky from a cloudy one, but even to distinguish high level clouds from medium or low.

  Title Urban park lighting as a source of botanical light pollution Type Journal Article
  Year 2019 Publication Photonics Letters of Poland Abbreviated Journal Photon.Lett.PL  
  Volume 11 Issue 3 Pages 90  
  Keywords Plants  
  Abstract That paper describesthe relative impact of anartificial lighting deviceon botanical light pollution, consideringspectral power distribution (SPD in the lighting area. This impact is described by the Relative-to-Moon Photosynthesis Index (RMPI)and Induced Phytochrome Index (IPr). We found that in the case when lighting is realized by using LED luminaires instead of high-pressure sodium (HPS) or metal halide (MH) lamps, the influence of spectral light on plant vegetation process amplifies. Additionally,our research shows that estimating botanical light pollution on the basis of lamps’CCT is not the best method and that using SPD is better for this purpose.

  Title Outdoor Areas Lighting with LEDs – the Competition Between Scotopic Efficacy and Light Pollution Type Journal Article
  Year 2019 Publication Photonics Letters of Poland Abbreviated Journal Photon.Lett.PL  
  Volume 11 Issue 3 Pages 75  
  Keywords Skyglow  
  Abstract In this paper the effect of spectral power distribution SPD

of typical outdoor LED lamps on star visibility index SVI was analyzed.

For those lamps the nearest color temperature CCT [K] and scotopic

efficacy lm/W] data are also provided. The SVI has been defined as a

ratio of its scotopic flux to scotopic flux created by full moon light. The

calculations show that there is a strong relation between CCT of LEDs

and SVI index. Low CCT of the lamps does not significantly affect their

SVI value. Unfortunately, those kind of lamps are less attractive in

applications because of their low .

  Title Artificial light sources as light pollutant of humans melatonin suppression Type Journal Article
  Year 2019 Publication Photonics Letters of Poland Abbreviated Journal Photon.Lett.PL  
  Volume 11 Issue 3 Pages 78  
  Keywords Human Health  
  Abstract Blue light emitted by LEDs might influence thenatural biological rhythm of a human being, whichcan beconsidered as environment pollution.In this paper the effect of the latest commercially available LEDs on melatonin suppression index (MSI) was analyzed. The research was based on spectral power distributionof a given LED(SPD) and melatonin suppression functionin reference to melatonin suppression under daylight (illuminant D65). The resultsof calculations show astrong correlation between CCT and MSI;however,MSI factor might vary for different LEDs with the same CCT.

  Title Conditional Controlled Light/Dark Cycle Influences Exercise-Induced Benefits in a Rat Model with Osteoarthritis: In Vitro and In Vivo Study Type Journal Article
  Year 2019 Publication Journal of Clinical Medicine Abbreviated Journal J Clin Med  
  Volume 8 Issue 11 Pages 1855  
  Keywords Animals; environmental lighting; inflammation; musculoskeletal homeostasis; physical exercise  
  Abstract Physical exercise has long been recommended as a treatment for osteoarthritis (OA), though its effects vary based on the exercise protocol. Here, we examined whether environmental lighting conditions influence the anti-inflammatory benefits of exercise in a rat model of OA. Moderate-intensity treadmill exercise (Ex) was performed for six weeks under a 12:12 h light/dark (L/D) cycle, and compared against rats housed in a 24 h continuous light (L/L) environment. L/L conditions were associated with serological changes shortly after OA induction, which exacerbated the inflammatory microenvironment in the joint. Differentiation capacity was also impaired in bone precursor cells isolated from normal rats maintained under L/L conditions, despite elevated inflammatory responses. Exercise training under L/L conditions led to increased corticosterone levels in the blood, which exacerbated the progression of cartilaginous and synovial lesions. Osteoporotic phenomena were also observed in exercise-trained rats maintained under L/L conditions, along with inflammation-induced catabolism in the gastrocnemius muscle. Aberrant light/dark cycle conditions were also found to be associated with suppression of splenic Cry1 expression in exercise-trained rats, leading to dysregulation of immune responses. Taken together, these data suggest that lighting condition may be an important environmental factor influencing the exercise-induced benefits on OA.
