![]() ![]() Likewise (and inversely), a 33 rpm record will inherently be able to hold more tracks, owing to the slower speed. TracksĪnother key difference between 33 vs 45 vinyl records is the amount of tracks that each can contain.Īs a 45 rpm record is being played a faster speed, there is an inherent deficit in the amount of tracks that can appear on a disc intended to be played at precisely this speed. This higher sound quality will translate through the larger stereo system upon which these tunes are usually played. These records will thus be played at 45 rpm for the sake of better sound quality, though the record player upon which they are played will tend to be more like a big set of decks. That being said, there is in some circles a trend of using 12 inch records to house extended singles and / or remixes instead. 12 inchĪs already elucidated (and something vinyl collectors from all over can tell you), the 12 inch record will more often than not be played at 33 rpm, for the purposes of fitting a whole album onto the however many discs make up the entire package. They are generally much thicker, and were originally made from shellac, hence why they were considered too unsafe and thus brought out of mass production. ![]() This was the original size of the vinyl disc, wherein they would be spun on record players at 78 rpm, the proposed ideal speed by Emile Berliner, though a speed that not all turntables can handle these days. Many manufacturers do not even produce them anymore, hence why there is such a lack of an in between size on the vinyl market. You are far less likely to find a 10 inch record out and about, unless you are on a particularly thorough sojourn of crate digging or storing records of old. I suppose it is not hard to see why this might be of use to some, where the binaries of 12 inch and 7 inch records at their regular speeds simply do not offer an in-between upon which to hold an apposite body of music. That being said, there are a number of releases (however small) that use 7 inch vinyl records at 33 rpm, though they are exceedingly rare. The higher speed is supposedly better for the sound quality of the music imbibed within the grooves, hence why the original progenitor of the gramophone, Emile Berliner, believed that the optimum speed for audio quality was around 80 rpm, and hence why 78 rpm was the go to speed at which to play records for such a long time. This size of vinyl record is almost certainly going to be played at 45 rpm, having become the standard speed for this kind of disc in the middle of the 20th century. ![]() ![]() The lines are not so clear cut, however, as there exist such things as 12 inch singles, which instead of holding a whole album seek to play an extended mix of a single or simply hold a longer form song without sacrificing any of the sound quality.įor this reason, a 12 inch single record spins at 45 rpm usually, particularly popular among various styles of dance music, where the audio quality over massive speakers is integral to the sanctity of the vibes. In fact, the term single comes from these days, when a single set of songs would be held on these 7 inch discs and played at 45 rpm for the sake of higher audio quality. Where 12 inch vinyl records are traditionally used to hold longer form releases like albums or EPs, the 7 inch has come to hold shorter releases, like shorter EPs and singles. The 7 inch record comes at the task of holding sound from quite a different angle. This tradition continues to this day, where the dichotomy of 33 vs 45 vinyl comes to symbolize the parallel dichotomy between 12 inch records and 7 inch records. This harkens back to the early days of vinyl technology when Columbia Records began selling these larger discs under the pretext that they could hold significantly more music than any other existing disc at the time, including a whole range of vinyl record types. A record played at 33 rpm will tend to be around 12 inches, in fact. Generally, a record that is played at 33 rpm is going to be larger than a record intended to be played at 45 rpm. One of the central differences between 33 vs 45 vinyl rpm is the respective sizes of these kinds of vinyl record speeds. Well, look no further, for today this is precisely what we will be elucidating for you, hoping to enlighten you on some of the key differences and points of consideration for an aesthetic appreciation of the variations between 33 vs 45 vinyl rpms. Are you trying to make sense of all the letters and numbers that have come to signpost so much of the record-collecting experience? Are you looking to find out the precise differences in the dichotomy between 33 vs 45 vinyl? ![]() ![]() ![]() It doesn't have to be long, even just a "please look for foobar in the text" can help already. ![]() Learn More Academic Price 119 199.00 Buy Academic Price 59.00 99.

![]() ![]() Na and K play a fundamental role in the distribution of fluids inside and outside cells. Na and K have an effect on the regulation of blood-pressure levels. It plays a protective role against cardiovascular disease by increasing endothelium-dependent vasodilation, improving lipid metabolism, reducing systemic inflammation and inhibiting platelet aggregation. The percentage of Mg existing in the body is 70% in the skeleton, with the rest in the cells. Another important element from a physiological point of view is Mg, which plays a key role in muscle contraction, gland secretion and nerve transmission. The latest research has determined that high Ca levels are a risk factor for cardiovascular disease. Ca is a major contributor in the prevention of cancer, as well as bone health. Essential trace elements are important for the biochemical and physiological functions of the human body. The main minerals essential for humans are calcium (Ca), phosphorus (P), potassium (K), sodium (Na) and magnesium (Mg), while iron (Fe), copper (Cu), zinc (Zn), manganese (Mn), iodine (I) and selenium (Se) are trace elements. Research carried out in Romania as well as in other countries in the world has shown that the highest concentrations of trace elements were obtained in the case of samples of vegetables and fruits grown in soils near mining operations as well as industrial areas. The impact on soil quality is mainly due to the addition of heavy metals, which can have an impact on soil biodiversity and, in the case of Cd, on food quality. ![]() The management of fertilizers and manure is relevant for the production of food, but simultaneously causes effects on the environment, due to the negative effects on air, soil and water quality. Contamination of food with heavy metals is influenced by the following factors: the composition of the soil, the genotype of the plant, the environment, and the type of fertilizers and pesticides used. “Food intake of plant-derived foods is a major fraction of human exposure that can endanger health”. In recent years, environmental contamination by heavy metals has been a global concern, due to their persistence and mobility between the biotic and abiotic spheres. The results on the content of macro elements and trace elements, as well as the assessment of the risk to human health when consuming the assessed vegetables, were within the limits of European Union (EU) and World Health Organization and Food and Agriculture Organization (WHO/FAO)legislation.Įven though nutrient deficiency is one of the major health concerns in both developed and developing countries, exceeding certain limits should not be overlooked. ![]() Following the determination of THQ, the values obtained followed the order THQ With > THQ Cd > THQ Pb > THQ Co > THQ Mn > THQ Zn > THQ Fe. The risk assessment for human health was determined on the basis of the estimated daily dose (EDI), the values of the target hazard coefficient (THQ), the values of the total target hazard coefficient (TTHQ) and the carcinogenic risk (CR). ![]() At the same time, based on the values obtained for trace elements, an assessment of the risk to human health in terms of consumption of the vegetables studied was carried out. The values obtained for the macro elements and trace elements were used as input data for the analysis of multivariate data, the principal component analysis (PCA) in which the vegetable samples were grouped according to their contribution of certain mineral elements, as well as according to some of the botanical families to which they belong. The atomic-absorption-spectrometry technique (FAAS) was used to evaluate the macro elements and trace elements. The purpose of this study was to evaluate the macro elements (Na, K, Ca, Mg) and trace elements (Cu, Mn, Fe, Cd, Pb, Zn, Co) in 24 samples of vegetables from four botanical families ( Solanaceae, Brassicaceae, Apiaceae and Amaryllidaceae), purchased from the market in Timișoara, Romania, both imported products as well as local products. It is very important that in the case of some minerals their content in vegetables is known, so that the recommended limits are not exceeded. However, in addition to minerals which are beneficial to the body, certain minerals with a negative influence on human health can sneak in. Vegetable consumption is recommended and encouraged by all nutritionists and doctors across the planet. ![]() |
