octyl methoxycinnamate and oxybenzone are common ingredients in sunscreen applications. these compounds work by absorbing ultraviolet (uv) b light (wavelength 280–320 nm), the uv light most associated with sunburn symptoms. what frequency range of light do these compounds absorb?
the relationship of wavelength and frequency will appear as:using the wavelength range given, 280-320 nm, frequency range will be calculated using the equation above and by converting the values to the proper units [readmore]each wavelength must be in meters:we need to calculate the frequency for both 280 and 320 nm:range of frequency will appear as 1.07x1015 to 9.38x1014 s-1

Maybe you mean TB lymphadenitis (tuberculosis).



  

Mycobacterium tuberculosis can indeed infect a variety of organ systems, including the lymph nodes. These bacteria usually enter through the respiratory tract, especially in people who come in close contact with other TB sufferers, children, the elderly, and people with poor immune system. Under normal conditions, this lymph node functions as a haven and proliferation of white blood cells in warding off infections, including TB infection. However, along with its development, this lymph node itself can actually become infected, so that arises lymphadenitis. Clinically, TB lymphadenitis sufferers will experience lumps (often in the neck, armpits, or groin) that are round, smooth, springy, and often feel painful, especially when pressed. Not only that, TB lymphadenitis can also make sufferers experience fever, excessive sweating, weight gain is difficult to rise, weakness, fatigue, and various other complaints.



  

Handling TB lymphadenitis is done by giving OAT (anti-TB drugs) that must be consumed by sufferers for at least 6 consecutive months. Every month, the patient will be re-evaluated by a doctor to assess his responsiveness to the treatment given. After more than 2 months of treatment, complaints will generally improve slowly.



  

However, you need to know, that the treatment of TB lymphadenitis must also be accompanied by appropriate natural treatments, including those related to diet, regulation of activities, and also lifestyle modification. This inadequate treatment is likely to make your mother appear to be undergoing improvement despite long-term treatment. It could also, the slow healing process occurs due to the non-optimal resistance of your mother's body, resistance (immunity) of bacteria to the treatment given, as well as a variety of other factors. Compared with other complaints. lumps in lymph nodes due to TB lymphadenitis often will indeed not disappear completely, even though the patient's status has recovered from illness.



  

The itching that your mother is experiencing right now could be a side effect of the OAT she is taking. It could also, this itching occurs due to other reasons, for example allergies, skin irritation, infections, disorders of liver function, disorders of the thyroid gland, dry skin, atopic dermatitis, contact dermatitis, and so on.



  

Our advice, you check your mother back to the doctor or a specialist in internal medicine in order to get the right treatment. Meanwhile, at home, help your mother do the following steps:







Take OAT as recommended by your doctor  

Give your mother healthy and nutritious food, containing rich calories and protein  

Give him too much to drink  

Let your mother take a break from exhausting activities  

Accompany him to exercise  

Create a clean, well-ventilated and well-lit environment  

If you or someone else around your mother shows symptoms of TB infection, see your doctor directly to treat them properly



Hope this helps ... more like retain oxygen intake /efficiency. hi,
welcome to icliniq.com.
i have seen the pictures you have attached along with the complaint (attachment removed to protect patient identity).
these are nothing but stains and calculus.
a layer of a chalk-like substance formed over the teeth surfaces especially on the back side of your lower teeth is the calculus. it is prone to get stained by various food substances and sometimes turn yellow to green.
the brown colored areas which you are concerned about at the moment are just external stains and occur due to drinking coffee or tea regularly or even because of smoking.
these are not because of the invisalign treatment but occur commonly with anyone.
the treatment is as simple as getting a professional cleaning done by your dentist. to maintain the clean teeth, you got to follow the oral hygiene instructions given by the dentist after then. antiseptics are used to sterilise surfaces of living tissue when the risk of infection is very high, such as during surgery or on wounds. commonly used antiseptics include inorganics like iodine and boric acid or organics like iodoform and some phenolic compounds. e.g. tincture of iodine (2-3% solution of iodine in an alcohol-water mixture) and iodoform serve as powerful antiseptics and is used to apply on wounds. a dilute aqueous solution of boric acid is a weak antiseptic used for eyes. various phenols are used as antiseptics. a dilute aqueous solution of phenol (carbolic acid) is used as antiseptic; however, phenol is found to be corrosive in nature. many chloro derivatives of phenols are more potent antiseptics than the phenol itself. they can be used with much lower concentrations, which reduce their corrosive effects. two of the most common phenol derivatives in use are trichlorophenol (tcp) and chloroxylenol (which is an active ingredient of antiseptic dettol). thymol obtained from oil of thyme (a spice plant) has excellent non-toxic antiseptic properties. oxygen in acne scars are caused by loss or damage to the dermal tissue. the most common type, depressed scars, are caused by thick strands of fibers that pull the skin downwards. treatment of these scars should both disrupt these fibers and trigger the production of healthy new collagen to fill up the depression. fractional lasers can reach to a maximal depth of 1mm while the newer microneedle rf (radiowaves) system that seem to be more effective can reach up to 3.5mm. due to their deeper penetration non insulated microneedle rf technologies (such as endymed’s intensif system) seem to be more efficient and safe than the fractional lasers, especially on darker skin types. before and after 1 micro needle rf treatment for acne scars (endymed intensif handpiece) <p>concepts and reason</p>
<p>the concept used to solve this problem is the formal charge calculation of the oxygen atoms present in the ozone molecule.</p>
<p>fundamentals</p>
<p>a charge that is assigned to an atom, which is present in the molecule, is represented as a formal charge. in two bonded atoms, a formal charge assumes that the electrons are equally shared between them. the formal charge is calculated using the following formula:</p>
<p>formal charge \(=\mathrm{v}-\mathrm{n}-\frac{\mathrm{b}}{2}\)</p>
<p>here, \(\mathrm{v}\) is the number of valence electrons, \(\mathrm{n}\) is the number of non-bonding electrons and \(\mathrm{b}\) is the number of bonding electrons.</p>
<p> </p>
<p>the structure is as follows:</p>

<p>the marked oxygen atom has 6 valence electrons. it contains 6 non-bonding electrons. the marked oxygen atom is bonded with one oxygen atom. therefore, the bonding electron of oxygen is \(2 .\) substitute the values in a formal charge formula to determine the formal charge of oxygen (marked).</p>

<p>explanation | common mistakes | hint for next step</p>
<p>the oxygen atom in the middle has 6 valence electrons and has 2 non-bonding electrons. the central oxygen atom is bonded with 1 double bond and 1 single bond. so, there is a total of 3 bonds containing 6 electrons (bonding electrons). the formal charge of the middle oxygen atom can be determined by substituting the values in a formal charge formula.</p>

<p>the oxygen atom present on the right side contains 6 valence electrons which have 2 non-bonded electrons. the marked oxygen is bonded with 1 double bond with a central oxygen atom. so, the number of bonding electrons is \(4 .\) the formal charge of the corner oxygen atom (right corner) can be determined by substituting the values in the formal charge formula.</p>
