Pyridoxine has been observed to be mostly stable at a neutral pH. (7) However, pyridoxine has several natural derivatives, one of which fluoresces at the same wavelength and another three that fluoresce at nearby wavelengths. (9) These derivatives could have the potential to both increase or decrease in fluorescence intensity based on the pH or chemical makeup of their environment. (9) The presence of these derivatives as well as the environment…

Light is an electromagnetic radiation that can be detected by humans. Electromagnetic radiation happens in an extremely large range of wavelengths from gamma rays to radio waves. Within that spectrum the wavelengths visible to humans are few. Light is very difficult to define, in the sense that scientist have been arguing weather light is a particle or a wave. Many experiments have been done to proof weather light is a particle or a wave. The truth is that light sometimes acts as a wave and…

balance the effects of the reactants by releasing gas (CO2). In Figure 3, the lowest transition is at 439.2 nm, which is slightly lower than the range of 476.2-625 nm as per Maccoll et al.’s study.6 The CO32- ligand absorbs light with the longest wavelength in this experiment, so the energy jump between molecular orbitals is very small in this complex. This is consistent with the expected…

PHOTOSYNTHESIS: WAVELENGTHS VS. DISTANCE Introduction: Every living being on Earth can be categorized by either autotroph or heterotroph. What do I mean autotroph or heterotroph? Humans and most animals are considered heterotrophs. Heterotrophs gain their energy from harvesting the energy that other living things have stored. An example of this would be a human having a turkey dinner or a rabbit enjoying some leafy greens. Each example shows a living thing, consuming another once living thing…

Detection wavelength: Individual dilutions of Dapagliflozin and Saxagliptin were prepared from standard stock solutions using methanol. Both the solutions were scanned over the range of 200-400nm on UV-VIS spectrophotometer, using medium scan speed. From the overlay spectra, using isobestic point (which is the wavelength where the molar absorptivity is the same for two substance that are inter- convertible), 210 nm has been selected as the detection wavelength for HPLC method. This…

and red #3 or red #40. To determine which dyes were present, a spectroscopic reading was taken of the purple Gatorade using an Ocean Optics Spectrometer, connected to a computer via Go Link!, and the peak absorbance and wavelengths were recorded and compared to the wavelengths of each sample dye. The closest matches were FD&C Red #40 and FD&C Blue #1, as discussed in the results and discussion sections of this paper.…

Call it what you will. An artificial forest. A hide-and-seek campground. A scientific laboratory. Maybe even Owens Valley Long Wavelength Array. Exciting discoveries are taking place here in Owens Valley. A large array of radio telescopes, designed in the shape of trees, lay scattered across the desert floor, making it look just like a dry forest, artificially. Of course, it would be nice to play a game of hide-and-seek there, hiding between 288 distinct radio antennas under the warm sun.…

The sun radiates energy in a wide range wavelength. Ultraviolet rays reach the earth surface in wavelengths that range between 290 and 400 nm. The impact of the wavelength to the surface of the earth is determined by size of the wavelength. When the wavelength is short, it causes a more energetic radiation that in turn creates more harm to the surface. Ultraviolet light is a form of electromagnetic radiation that is invisible to the human eye. The sun is a source of radiation that forms the full…

evolution of primate cone pigments raises interesting general questions in evolutionary genetics, and is reviewed extensively elsewhere (Jacobs, 1996, Nathans, 1999 and Surridge et al., 2003). Most mammals are dichromatic with L (long wavelength) and S (short wavelength) cone pigments, but Old-World monkeys (Catarrhini) and howler monkeys (Alouatta spp.) independently duplicated the single ancestral LWS/MWS gene, which is on the X-chromosome, to give separate LWS and MWS pigments. Pigment…

The skin is said to be the largest performing organ in the body due to its three layered skin which all perform different tasks simultaneously. The epidermis (outer layer) and the dermis (inner layer) are the two main top layers of the skin followed by the lower subcutaneous tissue. The epidermis is the main component of the skin because it contains millions of important cells called melanocytes (Gohara and Perez 1). These melanocytes produce melanin which provides the skin with pigment (skin…
