Quantification

The objective of the present study is to isolate piperine from the black pepper. Our attempt was to extract the piperine with petroleum ether from black pepper and isolation using the same solvent. It is very difficult to extract and isolate the piperine using a non-polar solvent like petroleum ether due to solubility. During our study, we observe that piperine have a very little solubility in the petroleum ether, at the same time the solubility of the resinous material in petroleum ether is…

Determination of Isoprenaline Hydrochloride Concentration Using Ultra Violet/ Visible Spectroscopy and Quantification of Sodium and Potassium Using Flame Spectroscopy Introduction In UV/VIS (ultraviolet-visible light) spectroscopy, light absorption as a function of various wavelengths gives data about electronic transitions within a solution [1]. The electronic transitions involve exciting an electron from one principle quantum state to another by the absorption of energy [2]. A change in…

This is a randomized, double-blind, and placebo-controlled trial of 19 male volunteers, aged 18 to 65 years, with a diagnosis of SZ established by the Structured Clinical Interview for DSM-IV-Axis I Disorders (SCID-I). The research participants followed a 1‐month resveratrol supplementation program which was covered by the Public Health Service at the Schizophrenia Program of Hospital de Clinicas de Porto Alegre (HCPA), Brazil. All participants had been on a stable dose of atypical…

figurative languages like imagery to express her adoration for her husband, also she says that she cherishes his love more than the tangible treasures in the world. According to the PowerPoint on Anne Bradstreet, “this shows an almost boundless quantification of her love” (McCune Slide 13). She goes on to describing her love for her husband as everlasting. In line 10, Bradstreet says, “The heavens reward thee manifold, I pray” (Bradstreet 465) by saying she lets the reader know that she strongly…

B. People often confuse focal points with BATNA 3) Determine your reservation point Reservation point is not determined by what are the negotiator wishes and hopes rather than by what the BATNA represents. The reservation point is basically a quantification of a negotiators BATNA with respect to other alternatives the monetization of the BATNA. The reservation point has the greater impact on final the final outcome. Developing a reservation point Brainstorm your alternatives. Alternatives must…

This paper aims to highlight key requirements a Powerlink Queensland Stakeholder Engagement Plan and compare it to a generic plan. PLQ values its stakeholders and strives to meet stakeholder expectation regardless of change. The scope of engagement remains optimistic of the ability to fulfill its corporate and mutual obligations. As an ethical transmission utility in Queensland, it publishes the challenges it is going through during this fiscal year and the plan is reviewed in 2017. The…

1. What is the role of customer service in higher education? To what degree should faculty be responsible for providing customer service in their teaching? Even if we embrace the problematic idea that students are customers, higher education cannot, and should not, embrace the business platitude that the customer is always right. The heart of the teacher-student relationship is, in my opinion, honest evaluation. Teachers promise to be fair and transparent in their evaluation; students promise…

examined to see how they are calculated and their relevance to the true operation of a social conscience on behalf of the organisation. Nevertheless, a judgement will be made on whether those measures used is a meaningful manner in which to attempt quantification of social responsibility or whether the underlying goal is actually…

Population and community-level impacts of feral cats on native fauna have been little studied, but evidence from several studies indicates that direct predation is the most important process involved (reference). Nevertheless, a study was conducted on the stomach contents of 390 feral felines in central Australia, between 1990 and 1994, in the Northern Territory. Felines victualed on a variety of invertebrates, reptiles, birds and mammals, including animals up to their own body mass in size.…

Alkylated polycyclic aromatic compounds (alkyl-PACs) are the major aromatic constituent of total PAH in crude oil and originated from incomplete combustion process. Whereas benzo[a]pyrene (BaP) is a well-known human carcinogen, dibenzothiophene (DBT) and retene (Ret) are not; however, all three compounds are important environmental pollutants. Their toxicity is not yet characterized. In this study, we used BaP (parent PAH), DBT and Ret (alkyl-PACs) to elucidate the mechanism of neurotoxicity…
