Ananas comosus L. (Pineapple) is one of the superior fruit commodities in Indonesia. The amount of production in 2016 pineapples placed fourth after bananas, oranges and mangoes which amounted to 1.4 million tons/year.  Pineapple production for East Kalimantan, Balikpapan city has an area of 8,572 hectares of pineapple with a production of 7,206 tons of pineapple. Pineapple skin contains 17.53% carbohydrates and 13.65% sugar. This led researchers to develop the manufacture of acetic acid from the skin waste of  Ananas comosus L. The research method consists of materials used namely, pineapple skin, water, granulated sugar, yeast, vinegar, ammonium sulfate, oxalic acid, sodium hydroxide, pp indicators and aquades obtained from STTI Bontang laboratory. The working procedure of this study consists of 3 stages of the method: the first fermentation stage with the  addition of Saccharomyces cerevisiae, the second fermentation stage with variations in the addition of the parent vinegar and the calculation of acetic acid levels with time intervals of 2 days /sample (days 16, 18, 20, 22 and 24). The third stage is carried out by alkaline method. Optimum results from research with the main variation of vinegar and fermentation time were obtained on the 20th day with the addition of a 2.3 mL vinegar master obtained a acetic acid content of 6.24 g/mL. Further researchers are expected to develop better analytical methods to make the concentration of acetic acid obtained more optimal.

Third Stage

So far, methods of dating fossil objects have allowed us to obtain a large amount of data that characterize the moisturization of our planet’s areas during different time intervals. At the same time, in some cases, fossil objects contain information about the characteristics of the climate of the epoch of their existence. The available dating is scattered and does not allow us to get an overall picture of the changes occurred. Therefore, the developed method of aggregate representation of dates is relevant. Scientific materials containing the desired dating are mainly presented on the Internet. Therefore, the target of the first stage is to identify the publications of interest. At the second stage, the dating found and its characteristics are summarized in table 1. At the third stage, the data in table 1 is converted to table 2, reflecting the change in the moisture content of regions with a 100 years sampling interval. At the fourth stage, a simple rule is applied to exclude two multidirectional trends in each cell of table 2. As a result of exclusion, only unidirectional signs remain in each cell that qualitatively characterize the moisture content of the studied regions. It seems that the dating found in a significant minority should be questioned. However, cases in which the number of exceptions exceeds the number of non-excluded characters require additional research. The proposed method is not limited either by the number of studies involved or by the dating methods used. The scientific novelty of the proposed method consists in the aggregate representation of known dating of fossil objects containing information about the characteristics of the climate of the epoch of its existence. The objectivity of the results obtained is based on the use of a variety of independent dating of fossil objects obtained by different methods for different periods and regions. The reliability of the results obtained will increase with the number of dating involved in the analysis.

The Coherence of Mary Barton: Romance, Realism, and Utopia

Mode Of Production

Critics have argued that Elizabeth Gaskell's first novel, Mary Barton (1848), is split by a conflict between the modes of realism and romance. But the conflict does not render the novel incoherent, because Gaskell surpasses both modes through a utopian narrative that breaks with the conflict of form and gives coherence to the whole novel. Gaskell not only depicts what Thomas Carlyle called the ‘Condition of England’ in her work but also develops, through three stages, the utopia that will redeem this condition. The first stage is romantic nostalgia, a backward glance at Eden from the countryside surrounding Manchester. The second stage occurs in Manchester, as Gaskell mixes romance with a realistic mode, tracing a utopian drive toward death. The third stage is the utopian break with romantic and realistic accounts of the Condition of England and with the inadequate preceding conceptions of utopia. This third stage transforms narrative modes and figures a new mode of production.

The aim of the research project solved at the University of Finance and administration is to construct a new bankruptcy model. The intention is to use data of the firms that have to cease their activities due to bankruptcy. The most common method for bankruptcy model construction is multivariate discriminant analyses (MDA). It allows to derive the indicators most sensitive to the future companies’ failure as a parts of the bankruptcy model. One of the assumptions for using the MDA method and reassuring the reliable results is the normal distribution and independence of the input data. The results of verification of this assumption as the third stage of the project are presented in this article. We have revealed that this assumption is met only in a few selected indicators. Better results were achieved in the indicators in the set of prosperous companies and one year prior the failure. The selected indicators intended for the bankruptcy model construction thus cannot be considered as suitable for using the MDA method.

The Voice

The first stage of this project aims to identify assessment measures which include items on voice-hearing by way of a systematic review. The second stage is the development of a brief framework of categories of positive experiences of voice hearing, using a triangulated approach, drawing on views from both professionals and people with lived experience. The third stage will involve using the framework to identify any positve aspects of voice-hearing included in the voice hearing assessments identified in stage 1.

The Dead

This article is a inquiry about how Barrès (1862-1923) handles the religious rite of pilgrimage. Barrès stages in his writings three successive forms of pilgrimage, revealing what is sacred to him at different times. The pilgrimage to a museum or to the birthplace of an artist is typical for the egotism and the humanism of the young Barrès, expressed in the Cult of the Self (1888-1891). After his conversion to nationalism, Barrès tries to unite the sons of France and to instill in them a solemn reverence for “the earth and the dead” ; for that purpose he encourages in French Amities (1903) pilgrimages to historical places of national importance (battlefields; birthplace of Joan of Arc), building what Nora later called the Realms of Memory. The third stage of Barrès’ intellectual evolution is exemplified by The Sacred Hill (1913). In this book the writer celebrates the places where “the Spirit blows”, and proves open to a large scale of spiritual forces, reaching back to paganism and forward to integrative syncretism, which aims at unifying “the entire realm of the sacred”.
