Omariniite, Cu8Fe2ZnGe2S12, the germanium analogue of stannoidite, a new mineral species from Capillitas, Argentina
Authors: Bindi Luca , Putz Hubert , Paar Werner H. , Stanley Christopher J. 
Published: September 2017

AbstractOmariniite, ideally Cu8Fe2ZnGe2S12, represents the Ge-analogue of stannoidite and was found in bornite-chalcocite-rich ores near the La Rosario vein of the Capillitas epithermal deposit, Catamarca Province, Argentina. The mineral is associated closely with three other Ge-bearing minerals (putzite, catamarcaite, rarely zincobriartite) and bornite, chalcocite, digenite, covellite, sphalerite, tennantite, luzonite, wittichenite, thalcusite and traces of mawsonite. The width of the seams rarely exceeds 60 μm, their length can attain several 100 μm. The mineral is opaque, orange-brown in polished section, has a metallic lustre and a brownish-black streak. It is brittle, and the fracture is irregular to subconchoidal. Neither cleavage nor parting are observable in the sections. In plane-polarized light omariniite is brownish-orange and has a weak pleochroism. Internal reflections are absent. The mineral is distinctly anisotropic with rotation tints varying between brownish-orange and greenish-brown. The average result of 45 electron-microprobe analyses is Cu 42.18(34), Fe 9.37(26), Zn 5.17(43), In 0.20(6), Ge 11.62(22), S 31.80(20), total 100.34(46) wt.%. The empirical formula, based on Σ(Me + S) = 25, is Cu8.04(Fe2.03In0.02)Σ2.05Zn0.96 Ge1.94S12.01, ideally Cu8+Fe2+Zn2+Ge24+S122-. Omariniite is orthorhombic, space group I222, with unit-cell parameters: a = 10.774(1), b = 5.3921(5), c = 16.085(2) Å, V = 934.5(2) Å3, a:b:c = 1.9981:1:2.9831, Z = 2. X-ray single-crystal studies (R1 = 0.023) revealed the structure to be a sphalerite derivative identical to that of stannoidite. Omariniite is named after Dr. Ricardo Héctor Omarini (1946–2015), Professor at the University of Salta, for his numerous contributions to the geology of Argentina.

Fashion: From attitudes to poses
Authors: Evans Caroline 
Published: September 2017

Abstract
Borrowing some of Aby Warburg’s methods from his Mnemosyne Atlas, this paper experiments with an anti-linear, non-teleological method of writing fashion history. It investigates fashion movement, gesture and pose, and their afterlife in images and objects. It thus looks at the intersection of time and the gesture, particularly in relation to the idea of the ‘now’, a central organising principle of fashion. To this end, it juxtaposes images of the body in motion from a wide range of sources, including scientific photography, etiquette manuals and fashion magazines. Spanning three centuries, though not chronologically, the images show a range of activities: not only fashion posing, but also tennis-playing, duelling, dancing, military marching, social gestures, and going to the races. The paper proposes that each image is charged with some quality or attribute that is also immanent in one or more of the others, even though they have no causal or temporal relationship.
Metadata: New perspectives on Aby Warburg’s ‘critical iconology’
Authors: von Müller Johannes 
Published: September 2017

Abstract
The article reassesses the renown ‘critical iconology’ practiced by Aby Warburg and confronts it with recent theories regarding metadata and the curatorship of information. A close examination of Robert Kitaj’s portrait Warburg as a Maenad (1961–62) affirms Warburg’s ‘combinatory experiments’ (Christopher D. Johnson) to be a main characteristic of his practice. Warburg seems to have operated by applying what can now be described as metadata to the processes of transmission of culture he was accessing in form of migrating images. Further, the insights he was able to gain, namely his famous notion of the ‘Pathosformel’, may have to be considered as a specific form of metadata too. This is of particular interest acknowledging that in the digital world the migration of images takes mainly place in the realm of metadata. Hence ideas put forward by Warburg are able contribute to a deeper understanding of such phenomena.
Speculating on the biography of an apparatus
Authors: Hennig Anke 
Published: September 2017

Abstract
In this article I will look at literary imagination and the ways it is undermined and transformed by its relationship to apparatuses. I will compare the apparatus of Aby Warburg’s library with Peter Dittmer’s recent poetic apparatus Die Amme (1992–2006) in order to find out how poetics gets trapped by, and responds to, the challenge of apparatuses by employing the logistics of writing. A key concern of this article is to determine the role that speculation plays in poetics, in the apparatuses that govern writing, and in the economics of both.
Hades as an accumulation of tertiary retentions
Authors: Stiegler Bernard 
Published: September 2017

Abstract
This article examines Aby Warburg’s enterprise as an anamnesis, as a question of memory in exosomatisation in relation to the pharmakon. Here the pharmakon is considered as a ‘support’ in relation to questions of ‘care’ and as a therapeutics, prescribing the way by which such a pharmakon can become or remain curative, rather than toxic. The discussion looks at how the pharmakon makes possible the transmission of the condition of knowledge, that is: as a preindividual milieu that contains, retains and re-activates traumatypes, providing opportunities for bifurcations in the future. Warburg’s employment of photographic montage is considered as an exploration of pharmacological possibilities inherent to tertiary retentions and providing the condition for revenance. Such revenance is proposed as the return of the serpent in absentia: as a new form of tertiary retention that today appears as digital tertiary retention. At stake is the libido’s economisation, interactivity and algorithmic governmentality all of which effect the faculties for dreaming, imagination and knowledge.
Multivariate statistics and visualisation in earth science
Authors: Irawan Dasapta Erwin 
Published: September 2017

It's not exist until it's shown on a map.
Earth scientists are known to have a close relationship with maps. But since a long time a go, they also known to use statistics to support their claims. However, this strategy has not been applied extensively in Indonesia. More scientists still separate the spatial component with the statistical component in an geological analysis, for instance. Moreover, given the heterogenity of a geological environment, then the analysis is more complex than ever. Multivarible/multi parameters environment is the cause. This collection is another effort that I made to share multivariate statistics and it's various usage for earth science or geoscience.
I started with 79 papers in this case using several keywords listed in the description. I only selected documents with DOI link, to ensure that the doc is in form of a paper or an abstract. It covers mostly principal component analysis (PCA) and cluster analysis (CA) in soil, geochemistry, and water quality researches.
Now anyone could apply multivariate statistics along with pretty and informative visualisation using free tools like R and Python, like this blog post showing an example of PCA using R.
As additional reference, I also recommend the visitor to have a look at Basic statistical concepts and methods for earth scientists, a USGS open report, writtern by Ricardo A. Olea in 2008.

Seven local pepper populations (Capsicum annuum L.) from different geographical regions of Kosovo, were evaluated for morphological traits, chemical composition, and antioxidant contents using standard analytical techniques. All local peppers populations were characterized for different morphological traits from seedling emergence to crop maturity. The total genetic variation for plant height (PH) was 11.72 cm or expressed in relative values was 27.94 %. Average of leaf area (LA) per plant was 2308.38 cm2, while the lowest value for LA was 1136 cm2. Yield per plant ranged from 265 to 691 g plant-1. The acidity level was ranging from 1.44 to 1.61 %, carbohydrates varied greatly from 4.21 to 6.07 %. Vitamin C (as ascorbic acid) content in fresh fruit ranged from 65.544 to 520.51 mg 100g-1 of fresh mass. Minerals were of reasonable levels with Fe (15.31 mg kg-1), Ca (216.71 mg kg-1), Na (406.01 mg kg-1), K (1851 mg kg-1), and Zn (5.74 mg kg-1).

Method of auto-configuration for corporate proxies
Authors: Villarroel Acosta Andrés Abelardo , Montenegro Marín Carlos Enrique , Gaona García Paulo Alonso , Nieto Acevedo Yuri Vanessa 
Published: September 2017

Introduction: The proxy servers offer many advantages in business and academia. One of their main uses is to protect both the network and its users, offering a secure and fast connection to multiple users who require a service such as Internet. However, manual proxy settings require time and expertise by the end user, which leads to the network being less user friendly. The article was written in 2016 in the faculty of Engineering of the Universidad Distrital Francisco José de Caldas, Bogotá, Colombia.
Methology: The paper has been elaborated at Colombia using a Cascade Model. Results: The article presents an introduction to proxy auto configuration and proxy servers, as well as a detailed explanation of the configuration methods.
Conclusions: The study demonstrates methods and times that can lead to the reduction in standard connection time through manual configuration vs. automatic proxy configuration. This was implemented as a real case study in a company.
Convergent validity of the Occupational Therapy Adult Perceptual Screening Test (OT-APST) with two other cognitive-perceptual tools in a South African context
Authors: Razemba Fadzai , Jacobs Lizelle , Franszen Denise 
Published: September 2017

Background and aim: Occupational therapists working in the field of neuro-rehabilitation need to use screening tools which demonstrate validity and reliability to correctly identify patients with cognitive-perceptual impairments. The Occupational Therapy Adult Perceptual Screening Test (OT-APST) is a screening tool which was developed to identify patients with visual perceptual problems and apraxia following a stroke or other forms of acquired brain injury. Other instruments available are the Loewenstein Occupational Therapy Cognitive Assessment (LOTCA) and the Rivermead Perceptual Assessment Battery (RPAB). These tools evaluate similar constructs such as visual agnosia, body scheme, unilateral neglect and constructional skills but are too lengthy to use as screening tools.The aim of the study was to determine the convergent validity of the OT-APST with two other cognitive-perceptual tools commonly used in South Africa, namely the Dynamic Occupational Therapy Cognitive Assessment (DLOTCA) Â and the RPAB when administered to patients with a primary diagnosis of stroke.Method: A quantitative cross-sectional study was conducted on a sample of 32 participants with a primary diagnosis of stroke. Participants completed the three tools and subscales were compared with the Dynamic Loewenstein Occupational Therapy Cognitive Assessment (DLOTCA) cognitive areas and the RPAB items.Results: Five subscales of the OT-APST had significant correlations with similar DLOTCA and/or the RPAB subscales. Only the Apraxia subscale did not correlate with the referencing tools.Conclusion: This study provides further evidence of the convergent validity of the OT-APST when compared to the DLOTCA and RPAB. Although the OT-APST was standardised on an Australian population, it proved to be another option of a visual perceptual screening tool to identifying visual perceptual problems in patients with stroke in South Africa.Key words: Cognitive-perceptual, Stroke, convergent validity, Occupational therapy Adult Perceptual Screening Test (OT-APST), Dynamic Occupational Therapy Cognitive Assessment (DLOTCA), Rivermead Perceptual Assessment Battery (RPAB).
