This light is common in LEDs (even when used in illumination products, unfortunately) as a carry-over from computer screen technology. Blue light is an essential component of white light. White can be made from either narrow-spectrum or broad-spectrum blue. For example, LED technology tends to combine narrow- spectrum blue and yellow, while other technologies include more cyan and red.

416x416px The antimicrobial spectrum of an antibiotic means the range of microorganisms it can kill or inhibit. Antibiotics can be divided into broad- spectrum antibiotics, extended-spectrum antibiotics and narrow-spectrum antibiotics based on their spectrum of activity. Detailedly, broad-spectrum antibiotics can kill or inhibit a wide range of microorganisms; extended- spectrum antibiotic can kill or inhibit Gram positive bacteria and some Gram negative bacteria; narrow-spectrum antibiotic can only kill or inhibit limited species of bacteria. Currently no antibiotic's spectrum can completely cover all types of microorganisms.

Ampicillin is a moderate- spectrum penicillin antibiotic with good cover against group A streptococcal infection, whilst flucloxacillin is a narrow-spectrum antibiotic with cover against Staphylococcus aureus. The combination covers the two most likely bacteria in cellulitis infections in the arm or leg.
|
|
Despite flucloxacillin being insensitive to beta-lactamases, some organisms have developed resistance to it and other narrow-spectrum β-lactam antibiotics including methicillin. Such organisms include methicillin-resistant Staphylococcus aureus, which has developed resistance to flucloxacillin and other penicillins by having an altered penicillin-binding protein.

The significance of PZN stems from its narrow-spectrum antibiotic activity. Most antibiotics in clinical use are broad-spectrum, acting against a wide variety of bacteria, and antibiotic resistance to these drugs is common. In contrast, PZN is antibacterial against only a small number of species, including Bacillus anthracis.

After three relapses, patients may be treated with oral fidaxomicin, a narrow-spectrum antibiotic. The usual dosage is 200 mg twice a day orally for 10 days. Fidaxomicin is considered to be superior to vancomycin for severe CDI. The major downside of treatment with fidaxomicin is the cost of medication.

Often, the exact species of bacteria causing the illness is unknown, in which case narrow-spectrum antibiotics can't be used, and broad-spectrum antibiotics are used instead. To know the exact species of bacteria causing the illness, clinical specimens need to be taken for antimicrobial susceptibility testing in a clinical microbiology laboratory.

Dicloxacillin is a narrow-spectrum β-lactam antibiotic of the penicillin class. It is used to treat infections caused by susceptible (non-resistant) Gram-positive bacteria.Product Information: DICLOXACILLIN SODIUM-dicloxacillin sodium capsule. Teva Pharmaceuticals USA Inc, Revised 8/2015 It is active against beta-lactamase-producing organisms such as Staphylococcus aureus, which would otherwise be resistant to most penicillins.
|
|
Flucloxacillin, also known as floxacillin, is a narrow-spectrum beta-lactam antibiotic of the penicillin class. It is used to treat infections caused by susceptible Gram-positive bacteria. Unlike other penicillins, flucloxacillin has activity against beta-lactamase-producing organisms such as Staphylococcus aureus as it is beta-lactamase stable. However, it is ineffective against methicillin-resistant Staphylococcus aureus (MRSA).
|

Bacteriocins are proteinaceous or peptidic toxins produced by bacteria to inhibit the growth of similar or closely related bacterial strain(s). They are similar to yeast and paramecium killing factors, and are structurally, functionally, and ecologically diverse. Applications of bacteriocins are being tested to assess their application as narrow-spectrum antibiotics. Bacteriocins were first discovered by André Gratia in 1925.

When the responsible pathogenic microorganism is already known or has been identified, definitive therapy can be started. This will usually involve the use of a narrow-spectrum antibiotic. The choice of antibiotic given will also be based on its cost. Identification is critically important as it can reduce the cost and toxicity of the antibiotic therapy and also reduce the possibility of the emergence of antimicrobial resistance.

Etoxazole is a narrow spectrum systemic acaricide used to combat spider mites. It targets a variety of mites in the egg, larvae and nymph stages however not the adult stage. It also exhibits insecticidal activity towards aphids, the green rice leafhopper and diamondback moth. The mode of action was originally suspected to inhibit the molting process but has since been shown to inhibit chitin synthesis.

Spatial coherence allows a laser to be focused to a tight spot, enabling applications such as laser cutting and lithography. Spatial coherence also allows a laser beam to stay narrow over great distances (collimation), enabling applications such as laser pointers and lidar. Lasers can also have high temporal coherence, which allows them to emit light with a very narrow spectrum, i.e., they can emit a single color of light.

Nafcillin sodium is a narrow-spectrum beta-lactam antibiotic of the penicillin class. As a beta-lactamase-resistant penicillin, it is used to treat infections caused by Gram-positive bacteria, in particular, species of staphylococci that are resistant to other penicillins. Nafcillin is considered therapeutically equivalent to oxacillin, although one retrospective study found greater rates of hypokalemia and acute kidney injury in patients taking nafcillin compared to patients taking oxacillin.

The first acoustic mines were deployed by the German navy in the Thames Estuary in October 1940. These mines could be set to broad spectrum or narrow spectrum sound signature. The broad setting would be triggered by the sound of any passing ship's propeller; the narrow would be set to only explode when the propellor of a large ship was detected. The US Navy deployed acoustic mines as an anti-submarine device from 1948.

Most simple cases will resolve on their own but first line treatments are typically topical medications. #Topical antiseptic treatment is adequate for most cases #Topical antibiotics, such as mupirocin or Neomycin/polymyxin B/bacitracin ointment may be prescribed. Oral antibiotics may also be used. #Some patients may benefit from systemic narrow-spectrum penicillinase-resistant penicillins (such as dicloxacillin in US, or flucloxacillin in UK) #Fungal folliculitis may require an oral antifungal such as Fluconazole.

Due to their toxicity, use of glycopeptide antibiotics is restricted to patients who are critically ill, who have a demonstrated hypersensitivity to the β-lactams, or who are infected with β-lactam-resistant species. These antibiotics are effective principally against Gram-positive cocci. They exhibit a narrow spectrum of action, and are bactericidal only against the enterococci. Some tissues are not penetrated very well by glycopeptides, and they do not penetrate into the cerebrospinal fluid.

In September 2016, Pernar participated in a discussion with LGBT portal Crol.hr about the LGBT community in Croatia. Pernar said that "homosexuals are not an endangered group", but stated that they are "one of a long series of groups which the clerical right turned their backs on." Pernar gave a mixed assessment of gay activism in Croatia, saying that "unfortunately, some gay activists reduce their struggle to a narrow spectrum of society".

Anidulafungin Discovery of echinocandins stemmed from studies on papulacandins isolated from a strain of Papularia sphaerosperma (Pers.), which were liposaccharide - i.e., fatty acid derivatives of a disaccharide that also blocked the same target, 1,3-β glucan synthase - and had action only on Candida spp. (narrow spectrum). Screening of natural products of fungal fermentation in the 1970s led to the discovery of echinocandins, a new group of antifungals with broad-range activity against Candida spp.

The output of the multiple oscillators was then summed and sent to the output. The AMY allowed the oscillators to be combined in any fashion, two at a time, to produce up to eight output channels. The output was then converted to analog in a separate (user-provided) digital-to-analog converter. While the additive synth system works well for sounds with a narrow spectrum, it is not useful for wider spectrum sounds like white noise.

Further categorization is based on their target specificity. "Narrow-spectrum" antibiotics target specific types of bacteria, such as gram-negative or gram-positive, whereas broad-spectrum antibiotics affect a wide range of bacteria. Following a 40-year break in discovering classes of antibacterial compounds, four new classes of antibiotics were introduced to clinical use in the late 2000s and early 2010s: cyclic lipopeptides (such as daptomycin), glycylcyclines (such as tigecycline), oxazolidinones (such as linezolid), and lipiarmycins (such as fidaxomicin).

A dye laser tuned to 589nm (amber yellow), pumped with an external, frequency-doubled Nd:YAG laser @ 532nm (yellowish-green). The closeness between wavelengths results in a very small Stokes shift, reducing energy losses. A laser of a suitable type can be used to pump another laser. The pump laser's narrow spectrum allows it to be closely matched to the absorption lines of the lasing media, giving it much more efficient energy transfer than the broadband emission of flashlamps.

Modern factory farming focuses solely on faster-growing animals, and a bottom line that reflects little interest in biodiversity, sustainability, healthy food, or animal welfare. Ancient breeds of livestock are becoming extinct. Right now, according to the Food and Agriculture Organization of the United Nations, three-fourths of the world’s food comes from just twelve types of plants and five animals. Such a narrow spectrum is a threat to food security: the implications of such monoculture is blight, either natural or manmade.

Narrow-spectrum antibiotics have low propensity to induce bacterial resistance and are less likely to disrupt the microbiome (normal microflora). On the other hand, indiscriminate use of broad-spectrum antibiotics may not only induce the development of bacterial resistance and promote the emergence of multidrug-resistant organisms, but also cause off-target effects due to dysbiosis. They may also have side effects, such as diarrhea or rash. Generally, a broad antibiotic has more clinical indications, and therefore are more widely used.

One recently developed, novel source of broad spectrum radiation is synchrotron radiation which covers all of these spectral regions. Other radiation sources generate a narrow spectrum but the emission wavelength can be tuned to cover a spectral range. Examples of these include klystrons in the microwave region and lasers across the infrared, visible and ultraviolet region (though not all lasers have tunable wavelengths). The detector employed to measure the radiation power will also depend on the wavelength range of interest.

A few antibiotics have received marketing authorization in the last seven years. The cephalosporin ceftaroline and the lipoglycopeptides oritavancin and telavancin for the treatment of acute bacterial skin and skin structure infection and community-acquired bacterial pneumonia. The lipoglycopeptide dalbavancin and the oxazolidinone tedizolid has also been approved for use for the treatment of acute bacterial skin and skin structure infection. The first in a new class of narrow spectrum macrocyclic antibiotics, fidaxomicin, has been approved for the treatment of C. difficile colitis.

Fidaxomicin binds to and prevents movement of the "switch regions" of bacterial RNA polymerase. Switch motion occurs during the opening and closing of the DNA:RNA clamp, a process that occurs throughout RNA transcription but is especially important in the opening of double-stranded DNA during the initiation of transcription. It has minimal systemic absorption and a narrow spectrum of activity; it is active against Gram positive bacteria, especially clostridia. The minimal inhibitory concentration (MIC) range for C. difficile (ATCC 700057) is 0.03–0.25 μg/mL.

SLEDs are optical sources with a rather wide optical bandwidth. In that they differ from both lasers, that have a very narrow spectrum, and white light sources, that exhibit a much larger spectral width. This characteristic mainly reflects itself in a low temporal coherence of the source (which is the limited capability of the emitted light wave to maintain the phase over time). SLEDs may however exhibit a high degree of spatial coherence, meaning that they can be efficiently coupled into single-mode optical fibers.

Enoyl-acyl carrier protein reductase (or ENR) (), is a key enzyme of the type II fatty acid synthesis (FAS) system. ENR is an attractive target for narrow- spectrum antibacterial drug discovery because of its essential role in metabolism and its sequence conservation across many bacterial species. In addition, the bacterial ENR sequence and structural organization are distinctly different from those of mammalian fatty acid biosynthesis enzymes. Image:FattyAcid-MB-Reduction2.png At lower concentrations, Triclosan and Triclocarban provide a bacteriostatic effect by binding to ENR.

Fidaxomicin, sold under the brand name Dificid among others, is the first member of a class of narrow spectrum macrocyclic antibiotic drugs called tiacumicins. It is a fermentation product obtained from the actinomycete Dactylosporangium aurantiacum subspecies hamdenesis. Fidaxomicin is minimally absorbed into the bloodstream when taken orally, is bactericidal, and selectively eradicates pathogenic Clostridium difficile with relatively little disruption to the multiple species of bacteria that make up the normal, healthy intestinal flora. The maintenance of normal physiological conditions in the colon may reduce the probability of recurrence of Clostridium difficile infection.

Once the crow attack and attic scenes were assembled by the film's editor, George Tomasini, they were sent to the special effects department for enhancement. The film required myriad special effects and Hitchcock commissioned the help of various studios. The special effects shots of the attacking birds were completed at Walt Disney Studios by animator/technician, Ub Iwerks, who used the sodium vapor process ("yellow screen"), which he had helped to develop. The SV process films the subject against a screen lit with narrow-spectrum sodium vapor lights.

A nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas detector. It is non-dispersive in the fact that no dispersive element (e.g a prism or diffraction grating as is often present in other spectrometers) is used to separate out (like a monochromator) the broadband light into a narrow spectrum suitable for gas sensing. The majority of NDIR sensors use a broadband lamp source and an optical filter to select a narrow band spectral region that overlaps with the absorption region of the gas of interest.

Photoluminescence (PL) imaging is done by use of an external light source to excite carrier inside the Silicon of the solar cells. If no circuit is applied or the load on the module is high enough, the excited carrier have no way to leave the solar cell and will recombine, resulting in luminescence radiation. The light source should have a narrow spectrum, like a LED or a homogenized diode laser, to allow easy separation of its own light to the luminescence signal. Additionally, separation can be assured by an long- pass or even a band-pass filter.

The mould Penicillium chrysogenum was the source of penicillin G. Many species produce metabolites that are major sources of pharmacologically active drugs. Particularly important are the antibiotics, including the penicillins, a structurally related group of β-lactam antibiotics that are synthesized from small peptides. Although naturally occurring penicillins such as penicillin G (produced by Penicillium chrysogenum) have a relatively narrow spectrum of biological activity, a wide range of other penicillins can be produced by chemical modification of the natural penicillins. Modern penicillins are semisynthetic compounds, obtained initially from fermentation cultures, but then structurally altered for specific desirable properties.

ESBL enzymes can hydrolyze all beta-lactam antibiotics, including cephalosporins, except for the carpabepenems. The first clinically observed ESBL enzymes were mutated versions of the narrow spectrum beta-lactamases, like TEM and SHV. Other ESBL enzymes originate outside of family Enterobacteriaceae, but have been spreading as well. In addition, since the plasmids that carry ESBL genes also commonly encode resistance determinants for many other antibiotics, ESBL strains are often resistant to many non-beta- lactam antibiotics as well,Broad spectrum antibiotics and resistance in non- target bacteria: an example from tetracycline, Journal of Pure and Applied Microbiology, (2014); 8(4): 2667-2671.

Researchers at Utah State University compared measurements for PPF and YPF using different types of equipment. They measured the PPF and YPF of seven common radiation sources with a spectroradiometer, then compared with measurements from six quantum sensors designed to measure PPF, and three quantum sensors designed to measure YPF. They found that the PPF and YPF sensors were the least accurate for narrow-band sources (narrow spectrum of light) and most accurate broad-band sources (fuller spectra of light). They found that PPF sensors were significantly more accurate under metal halide, low-pressure sodium and high- pressure sodium lamps than YPF sensors (>9% difference).

In the late 1990s, Edwards co-founded and served as CEO of Borealis Biosciences and Chalon Biotech, which he merged to form Affinium Pharmaceuticals, a Toronto- based company. Affinium developed afabicin, a novel narrow-spectrum antibiotic that is now in clinical development at DebioPharm. Several other companies have been spun out of his research programs, including Harbinger Biotechnology and Engineering, which was acquired by Epiphyte3, and 1DegreeBio, which was acquired by LabX Media Group. More recently, Edwards founded M4K Pharma, a company that is developing a brain-penetrant drug targeting the ALK2 kinase, in order to treat children with incurable diffuse-intrinsic pontine glioma (DIPG).

The costs of maintaining its military, the KGB, and subsidies to foreign client states further strained the moribund Soviet economy. Ronald Reagan and Mikhail Gorbachev in Red Square, Moscow, 1988 The first signs of major reform came in 1986 when Gorbachev launched a policy of glasnost (openness) in the Soviet Union, and emphasized the need for perestroika (economic restructuring). By the spring of 1989, the Soviet Union had not only experienced lively media debate, but had also held its first multi-candidate elections in the newly established Congress of People's Deputies. While glasnost ostensibly advocated openness and political criticism, these were only permitted within a narrow spectrum dictated by the state.

Empiric antimicrobial therapy is typically broad-spectrum, in that it treats both a multitude of either Gram-positive and/or Gram-negative bacteria, diverse fungi or parasites respectively. When more information is known (as from a blood culture), treatment may be changed to a narrow-spectrum antimicrobial which more specifically targets the bacterium or fungus known to be causing disease. Empiric antimicrobial therapy is a fairly sophisticated process which includes considering data such as a person's age, immune status, comorbidities, likelihood for a certain microbial etiology and pre-test probability for antimicrobial resistance prior to therapy, risk of bad outcomes, and to name a few. Specimens are collected from affected body sites, preferably before antibiotics are given.

Critics of the role of the media in liberal democracies allege that concentration of media ownership leads to major distortions of democratic processes. In Manufacturing Consent: The Political Economy of the Mass Media, Edward S. Herman and Noam Chomsky argue via their Propaganda ModelEdward S. Herman "The Propaganda Model Revisited" , Monthly Review, July 1996, as reproduced on the Chomsky.info website that the corporate media limits the availability of contesting views and assert this creates a narrow spectrum of elite opinion. This is a natural consequence, they say, of the close ties between powerful corporations and the media and thus limited and restricted to the explicit views of those who can afford it.

Radio 2 began in Blacktown, New South Wales in Western Sydney on 1611 AM in October 2001, broadcasting under a Section 40 licence - meaning it could only operate on narrowband AM frequencies (1611–1701 kHz), and with narrow spectrum - 5 kHz, rather than the full 9 kHz which other commercial radio stations use. Branded "The New Voice Of Western Sydney", the station focused on live and local content, similar to 2WS in its heyday. In 2002, Radio 2 was a broadcast partner of the 2002 FIFA World Cup, broadcasting live coverage of matches, with the call lead by Colin Turner. In 2003, Radio 2 was a broadcast partner of the AFL, hosting live coverage of Sydney Swans home games from the SCG and Telstra Stadium.

It is not recommended for use with benzoyl peroxide due to the risk of causing yellow- orange skin discoloration with this combination. Minocycline is an effective acne treatment, but it is not a first-line antibiotic due to a lack of evidence that it is better than other treatments, and concerns about its safety compared to other tetracyclines. Sarecycline is the most recent oral antibiotic developed specifically for the treatment of acne, and is FDA- approved for the treatment of moderate to severe inflammatory acne in patients nine years of age and older. It is a narrow-spectrum tetracycline antibiotic that exhibits the necessary antibacterial activity against pathogens related to acne vulgaris and a low propensity for inducing antibiotic resistance.

A colored electron microscopy image of methicillin-resistant staphylococcus aureus (MRSA), a bacteria commonly targeted by broad-spectrum antibiotics A broad-spectrum antibiotic is an antibiotic that acts on the two major bacterial groups, gram-positive and gram-negative, or any antibiotic that acts against a wide range of disease-causing bacteria. These medications are used when a bacterial infection is suspected but the group of bacteria is unknown (also called empiric therapy) or when infection with multiple groups of bacteria is suspected. This is in contrast to a narrow-spectrum antibiotic, which is effective against only a specific group of bacteria. Although powerful, broad-spectrum antibiotics pose specific risks, particularly the disruption of native, normal bacteria and the development of antimicrobial resistance.

Large resonant light depth is the premise of constructing efficient quantum-optical memory. Alkali metal vapor isotopes of a large number of near-infrared wavelength optical depth, because they are relatively narrow spectrum line and the number of high density in the warm temperature of 50-100 ∘ C.Alkali vapors have been used in some of the most important memory developments, from early research to the latest results we are discussing, due to their high optical depth, long coherent time and easy near-infrared optical transition. Because of its high information transmission ability, people are more and more interested in its application in the field of quantum information. Structured light carries the orbital angular momentum, which must be stored in the memory is to faithfully reproduce the stored structural photons.

The hellbender salamander, considered a "habitat specialist", has adapted to fill a specific niche within a very specific environment, and is labeled as such "because its success is dependent on a constancy of dissolved oxygen, temperature and flow found in swift water areas", which in turn limits it to a narrow spectrum of stream/river choices. As a result of this specialization, hellbenders are generally found in areas with large, irregularly shaped, and intermittent rocks and swiftly moving water, while they tend to avoid wider, slow-moving waters with muddy banks and/or slab rock bottoms. This specialization likely contributed to the decline in their populations, as collectors could easily identify their specific habitats. One collector noted, at one time, "one could find a specimen under almost every suitable rock", but after years of collecting, the population had declined significantly.

Two identical waves which consist of a narrow spectrum of frequency waves of finite duration, will give a series of fringe patterns of slightly differing spacings, and provided the spread of spacings is significantly less than the average fringe spacing, a fringe pattern will again be observed during the time when the two waves overlap. Conventional light sources emit waves of differing frequencies and at different times from different points in the source. If the light is split into two waves and then re-combined, each individual light wave may generate an interference pattern with its other half, but the individual fringe patterns generated will have different phases and spacings, and normally no overall fringe pattern will be observable. However, single-element light sources, such as sodium- or mercury- vapor lamps have emission lines with quite narrow frequency spectra.
