Study On Impact of Sound Frequency on Human Well Being Using Randomized Block Design

This study summarizes the exploration of the impact of sound frequencies on various dimensions of human well-being. The study investigates the psychological and physiological responses to different sound frequencies, considering factors such as emotional states, focus, stress relief, and pain perception. The experiment draws on established psychoacoustic principles and incorporates data from controlled experiments, including a Randomized Block Design (RBD). The study employs statistical analyses, such as ANOVA, to discern the significance of Intercept, Block Number, and Sound Frequency in predicting variations in well-being outcomes.the study revealed valuable insights into the factors influencing different dimensions of human well-being. The consistent significance of Intercept, Block Number, and Sound Frequency across various aspects suggests the importance of considering both individual and external factors, as well as the specific frequencies of sounds, in understanding and promoting well-being. These findings can have implications for designing interventions or environments that aim to enhance different aspects of human well-being through targeted sound exposure

Properties of a class of multivalent functions starlike with respect to symmetric and conjugate points 1

Abstract Let S be the class of functions analytic and multivalent in the open unit disc given by a p+n z p+n and a n ∈ C. In this paper we have studied three subclasses consisting of analytic functions with negative coefficients and starlike with respect to symmetric points, starlike with respect to conjugate points and starlike with respect to symmetric conjugate points, respectively. Here, we discuss coefficient inequality, growth and distortion theorems, extreme points, closure theorems and convolution properties of these classes. 2000 Mathematics Subject Classification: 30C45, 30C50

Mechanical pruning and soil organic amendments in vineyards of Syrah: effects on wine mineral composition

The interaction of mechanized pruning systems and soil organic amendment can affect vine vegetative and reproductive growth. However, since organic amendments supply several mineral elements, namely heavy metals, this study aimed to understand the effects of the interaction between these two practices on the mineral composition of wine. Two field trials were implemented in ‘Syrah’ vineyards in two Portuguese wine regions (Lisboa and Tejo). Mechanical hedge pruning was compared with hand spur pruning and four different organic amendments were tested: biochar, municipal solid waste compost, cattle manure and sewage sludge. The nitrogen (N), phosphorus (P) and potassium (K) wine contents were significantly reduced by mechanical pruning while calcium (Ca) and magnesium (Mg) contents were tendentially higher in this pruning system. Mechanical pruning also reduced the content of some minor elements, such as arsenic (As), molybdenum (Mo) and nickel (Ni). In 2014, the year with the higher reproductive growth, some other elements also decreased as a consequence of the mechanical pruning (gallium - Ga; lithium – Li; rubidium - Rb, thallium – Tl; yttrium - Y). Concerning the organic amendments, sewage sludge was associated with the wines with the lowest P and iron (Fe) content. Ca content was tendentially higher in municipal solid waste compost and sewage sludge treatments. Mechanical pruning and organic amendments had different effects on the mineral composition of wine, according to each specific element. However, the legal limits, recommended by OIV and established by European Union, as well as the technical limits, adopted by winemakers, were never exceeded and the interaction of both practices does not seem to be a problem in what concerns to the mineral composition of the produced winesA interação entre a poda mecânica e a aplicação de corretivos orgânicos ao solo pode afetar o crescimento vegetativo e reprodutivo da videira. No entanto, uma vez que os corretivos orgânicos fornecem vários elementos minerais, nomeadamente metais pesados, este estudo teve como objetivo compreender os efeitos da interação entre estas duas práticas na composição mineral do vinho. Foram implementados dois ensaios em vinhas de ‘Syrah’, em duas regiões vitivinícolas Portuguesas (Lisboa e Tejo). A poda mecânica em sebe foi comparada com a poda manual e quatro diferentes corretivos orgânicos foram testados: biochar, resíduos sólidos urbanos compostados, estrume de bovino e lamas de uma estação de tratamento de águas residuais. Os teores de azoto (N), fósforo (P) e potássio (K) no vinho foram significativamente reduzidos pela poda mecânica, enquanto os teores de cálcio (Ca) e magnésio (Mg) foram tendencialmente maiores neste sistema de poda. A poda mecânica também reduziu o teor de alguns elementos minoritários, como arsénio (As), molibdénio (Mo) e níquel (Ni). Em 2014, o ano de maior crescimento vegetativo e reprodutivo, alguns outros elementos também foram reduzidos pela poda mecânica (gálio - Ga; lítio – Li; rubídio – Rb; tálio – Tl; ítrio Y). No que diz respeito aos corretivos orgânicos, as lamas de depuração produziram os vinhos com os menores teores de P e ferro (Fe). O teor de Ca foi tendencialmente mais elevado na modalidade com resíduos sólidos urbanos compostados e lamas de estação de tratamento de águas residuais. A poda mecânica e os corretivos orgânicos tiveram efeitos diferentes na composição mineral do vinho, de acordo com cada elemento específico. No entanto, os limites legais, recomendados pela OIV e estabelecidos pela legislação da União Europeia, e os limites técnicos adotados pelos enólogos nunca foram ultrapassados, pelo que a interação de ambas as práticas não parece ser um problema no que diz respeito à composição mineral dos vinhos produzidosinfo:eu-repo/semantics/publishedVersio

Fate and effect of antibiotics in beef and dairy manure during static and turned composting

Manure composting has general benefits for production of soil amendment, but the effects of composting on antibiotic persistence and effects of antibiotics on the composting process are not well-characterized, especially for antibiotics commonly used in dairy cattle. This study provides a comprehensive, head-to-head, replicated comparison of the effect of static and turned composting on typical antibiotics used in beef and dairy cattle in their actual excreted form and corresponding influence on composting efficacy. Manure from steers (with or without chlortetracycline, sulfamethazine, and tylosin feeding) and dairy cows (with or without pirlimycin and cephapirin administration) were composted at small scale (wet mass: 20-22 kg) in triplicate under static and turned conditions adapted to represent US Food and Drug Administration guidelines. Thermophilic temperature (>55°C) was attained and maintained for 3 d in all composts, with no measureable effect of compost method on the pattern, rate, or extent of disappearance of the antibiotics examined, except tylosin. Disappearance of all antibiotics, except pirlimycin, followed bi-phasic first-order kinetics. However, individual antibiotics displayed different fate patterns in response to the treatments. Reduction in concentration of chlortetracycline (71-84%) and tetracycline (66-72%) was substantial, while near-complete removal of sulfamethazine (97-98%) and pirlimycin (100%) was achieved. Tylosin removal during composting was relatively poor. Both static and turned composting were generally effective for reducing most beef and dairy antibiotic residuals excreted in manure, with no apparent negative impact of antibiotics on the composting process, but with some antibiotics apparently more recalcitrant than others

Mechanical pruning and soil organic amending in two terroirs. Effects on wine chemical composition and sensory profile

The knowledge about the interaction between mechanical pruning and soil organic amending is still scarce. This study aimed to examine the effects of the interaction between these two practices on wine quality. Syrah grapes from two trial fields in Portugal subjected to two different pruning systems (mechanical pruning; hand spur pruning) and five different organic amendment treatments (control, biochar, municipal solid waste compost, cattle manure, and sewage sludge) were harvested and vinified for four years. Mechanical pruning significantly reduced wine alcoholic strength, pH, and total anthocyanins. Mechanical pruning and organic amendments, tendentially reduced wine total phenols and tannin power, known as an “estimation of the astringency potential of the wines”. Tasters found low but significant differences in global appreciation with the pruning system. Sludge tended to reduce wine global appreciation more than municipal solid waste compost and cattle manure, while biochar had no effect on tasters’ preference when compared to the control. There was strong relation between yield and tasters’ preference only above 6 kg/vine and 8 kg/vine depending on the terroir. Mechanical pruning tendentially has significant effects on wine quality when yield raises above a certain level. Thus, with this pruning system, the choice of the organic amendment and its amount must be done considering the destiny of the produced grapes. To the best of our knowledge, effects of the interaction of mechanical pruning with soil organic amending on wine quality are a noveltyinfo:eu-repo/semantics/publishedVersio

Virus-Induced Type I Interferon Deteriorates Control of Systemic Pseudomonas Aeruginosa Infection

BACKGROUND: Type I interferon (IFN-I) predisposes to bacterial superinfections, an important problem during viral infection or treatment with interferon-alpha (IFN-alpha). IFN-I-induced neutropenia is one reason for the impaired bacterial control; however there is evidence that more frequent bacterial infections during IFN-alpha-treatment occur independently of neutropenia. METHODS: We analyzed in a mouse model, whether Pseudomonas aeruginosa control is influenced by co-infection with the lymphocytic choriomeningitis virus (LCMV). Bacterial titers, numbers of neutrophils and the gene-expression of liver-lysozyme-2 were determined during a 24 hours systemic infection with P. aeruginosa in wild-type and Ifnar(-/-) mice under the influence of LCMV or poly(I:C). RESULTS: Virus-induced IFN-I impaired the control of Pseudomonas aeruginosa. This was associated with neutropenia and loss of lysozyme-2-expression in the liver, which had captured P. aeruginosa. A lower release of IFN-I by poly(I:C)-injection also impaired the bacterial control in the liver and reduced the expression of liver-lysozyme-2. Low concentration of IFN-I after infection with a virulent strain of P. aeruginosa alone impaired the bacterial control and reduced lysozyme-2-expression in the liver as well. CONCLUSION: We found that during systemic infection with P. aeruginosa Kupffer cells quickly controlled the bacteria in cooperation with neutrophils. Upon LCMV-infection this cooperation was disturbed
