Field Test of U-Champ Biosurfactant in Oil Spill Bioremediation

One of the serious environmental problems of the oil and gas industry is handling oil spills. Oil spills can be managed by using bioremediation in the form of biosurfactants. In this research, biosurfactants called U-Champ were used which can impact in remediation of oil spills. The research conducted was testing the effectiveness of biosurfactants on Cepu Field contaminated soil in reducing TPH and heavy metals. The method is done by stirring the contaminated soil with various concentrations of biosurfactant product in an artificial tank. Based on the test results, a decline in TPH and TCLP along with the increase in U-Champ biosurfactant concentration was used. The addition of 6 Liters of biosurfactant gave the most significant reduction. Some of the heavy metals in the soil decrease, but some also have increased. As an example, it can be seen in Ba metal, the addition of U-Champ biosurfactant as much as 1.5 L (0.3% v / v) resulted in a decrease in TCLP of 11.085%. The qualitative result is evidenced by the growth of various plants in each artificial tank.

Persistence of antibody response to SARS-CoV-2 in a cohort of haemodialysis patients with COVID-19

Background Haemodialysis patients are extremely vulnerable to COVID-19. Their immune response after infection is unclear. We have found high seroconversion rates in this population with 95% developing antibodies. It is unclear if and how long these antibodies persist. Here we investigate this with serial antibody testing. Methods We identified haemodialysis patients who had confirmed SARS-CoV-2 between March-May 2020 and measured monthly antibodies (IgG/IgM) in those who survived. We used a semi-quantitative cut-off index (COI) to create a qualitative result and plotted optical density (OD) over time. We used linear regression to examine the slope, as well as noting peak OD and time to peak OD. We correlated these against baseline demographics, markers of illness severity, and comorbidities. Results 122 patients were analysed. All remained antibody positive during follow-up; for a minimum of 148 days. 71% had a positive gradient indicating increasing antibody positivity over time. We found that age (p = 0.01), duration of PCR positivity (p = 0.06) and presence of symptoms (p = 0.05) were associated with a longer time to peak OD. Immunosuppression did not alter peak OD but did lead to a non-significant increase in time to peak OD and more patients had a subsequent fall in Ab levels (p = 0.02). Diabetic patients were more likely to have a positive slope (OR 2.26). Conclusions These results indicate that haemodialysis patients have a robust and sustained antibody response after confirmed COVID-19 infection with no suggestion that immunosuppression weakens this response. Although unclear what protection these antibodies confer, this encouraging that haemodialysis patients should respond to vaccination.

Quantified educational texts as a means of improving the quality of procedural aspect of the educational process

The article is devoted to the analysis of the matters related to the quality of education. Having analyzed the theoretical and methodological views of scientists in this sphere, the authors have come to the conclusion that the quality of education should be considered as a unity of the quality of process, conditions and result. At the same time, the quality of the educational process accompanied by the adequate quality of pedagogical conditions for the course of this process can provide a qualitative result. In the authors’ opinion, improvement of the quality of procedural aspect of the educational process appears to be connected with using of quantified educational texts. Analysis of the conceptual questions of Professor V.S. Avanessov’s theory of pedagogical measurements has allowed the authors of the article to clarify such methodologically important terms, as: “text”, “educational text”, “quantum”, “quantifying”, which make up the structure of the concept “quantified educational text”, namely - divided into small indivisible parts training text, from which all the minor information is removed, and complex language formulations are replaced with more understandable ones for the target audience. Moreover, each of the semantic fragments has a concise heading that reflects the information contained in this fragment (quantum). The article also outlines the basic characteristics of quantified educational texts, as well as provides step-by-step instruction for quantifying of educational information. Need for using of quantified educational texts to improve the quality of procedural aspect of the educational process is substantiated by the memorability and better comprehensibility of the educational information represented in a quantified form, what is also confirmed by the research of communicative linguistics.

Evolution of New Integrated Haze Removal Algorithm Based On Haze Line

Haze is a standout amongst the most essential factor that debases the outside pictures. Picture corruption relies upon the separation of the Object from the camera as the separation increment from the camera of the scene point haze additionally increases. This paper presents a haze removal technique which is relies on the Haze-line prior that is recently introduced. This prior is based on the observation that the pixel values of a hazy image can be modeled as lines in RGB space that intersect at the airlight proposed approach is known as haze line. In this paper we proposed Post processing CBMG (Contrast, Brightness, Midtone and Gama adjustment) followed by four stages: clustering the pixel into haze line, Estimation of Transmission map, Regularization, Dehazing, This method is implement by observation of two basic things first pixels in a given group are regularly non local . Second pictures with improved perceivability (or sunny morning picture) have more differentiation than the pictures stopped by terrible climate. Experimental result demonstrate that our method remove haze layer and provide qualitative result.

Rural Settings and Two Brazils Very Brazilians

The rural settlements are managed through institutional organizations and established through laws, statute, projects, and forming an Ideal Brazil. Primarily, five elementary aspects need support from the government to develop socio-economically from those rural segments: Health service, school education, traffic conditions, qualification courses, and release of subsidies. On the other hand, there is a real Brazil lived by families farmers that face daily difficulties and the bureaucratic barriers. Research made by the ethnographic method, data collected by the technique of participant observation with 70 settlers. Records in a field diary analyzed the five aspects mentioned with the quantitative and qualitative result. This duality of views between Ideal Brazil and Real Brazil evidenced two Brazils "way Brazilian", demonstrating when theory and practice do not harmonize they compromise the socioeconomic aspects of rural settlements in your essence. Which is family agriculture. The INCRA represents the diagram of the power exerted upon the settlers, while those explore “Brazilian way" [jeitinho brasiliero] making an antagonistic duality instead of complementary. Assentamentos Rurais e Dois Brasis Bem Brasileiros Os assentamentos rurais são geridos por órgãos institucionais, com aspectos fiscalizadores, norteadores, financeiros, ofertando terras e capacitações, disponibilizando subsídios, coordenando instruções normativas através de leis, decretos, projetos, formando o Brasil Ideal. Por outro viés, há o Brasil Real, no seu cotidiano, analisando em cinco aspectos elementares: saúde pública, educação escolar, condições de trafegabilidade, cursos capacitatórios, liberação de subsídios. Pesquisa pelo método etnográfico, coleta de dados pela técnica da observação participante, registros em Diário de Campo, analisados nos aspectos quanti e qualitativos. Essa dualidade de olhares evidenciou dois brasis bem brasileiros, demonstrando que quando teoria e prática não se harmonizam, comprometem os aspectos socioeconômicos dos assentamentos rurais em sua essência, que é a agricultura familiar. O INCRA representa o diagrama do poder exercido sobre os assentados, enquanto esses se utilizam de “jeitinho brasileiro”, formando uma dualidade antagônica, ao invés de complementares.

PENERAPAN PSAK NO. 45 REVISI TAHUN 2015 PADA YAYASAN MADRASAH IBTIDAIYAH BAITUL MAKMUR KOTA KOTAMOBAGU

Along with the times, now a non-profit organization has been growing rapidly, for example a foundation engaged in educational, religious, health and others. Kotamobagu State Islamic Elementary School is an example of a foundation that is engaged in the field of education are categorized into non-profit organizations because it has the resources coming from student fees and parental contributions. As with any profit organizations, non-profit organizations also require knowledge of accounting to record expenses and revenues.

Feasibility Study on a Measurement Method and a Portable Measuring System to Estimate the Concentration of Cloxacillin andβ-Lactamase in Milk

Antibiotics are nowadays used and abused worldwide in common veterinary practice to treat diseases, prevent infections, and promote animal’s growth. Drug resistance occurrence is a relevant phenomenon that can inactivate the antibiotic. Moreover, antibiotics used for animals are also found in milk and it poses serious health risks to humans. Another negative effect is related to milk processors since antibiotics cause detrimental effects on cheese and yogurt starter bacteria. Given its consumption as both beverage and derivatives, milk is one of the most regulated products in food industry. Nowadays several commercial tests are available to investigate antibiotics in milk, but they generally provide a qualitative result, require bulky procedure, and are time consuming. In this paper, we investigate the use of a chromogenic cephalosporin to quantify the concentration of cloxacillin—aβ-lactam difficult to be detected by using “cowside” screenings which is the drug of choice in the method of mastitis control. The proposed measurement method and prototype have been demonstrated to be able to detect cloxacillin in milk at concentrations lower than the MRL set by the European Commission. Moreover, they are also able to detect the illegal practice of usingβ-lactamase to degradeβ-lactams in milk.

On Systems of Complexity One in the Primes

Consider a translation-invariant system of linear equationsVx= 0 of complexity one, whereVis an integerr×tmatrix. We show that ifAis a subset of the primes up toNof density at leastC(log logN)–1/25t, there exists a solutionx∈ AttoVx= 0 with distinct coordinates. This extends a quantitative result of Helfgott and de Roton for three-term arithmetic progressions, while the qualitative result is known to hold for all translation-invariant systems of finite complexity by the work of Green and Tao.
