Antibiotic are secondary metabolites yielded by microbe especially fungus. Previous research succesfull screened four kinds of fungus that live in termites queen’s nest, one of them was Aspergillus flavus. Furthermore, Alen et al (2016g) states that this fungus last to produce metabolite compounds on SDA media which only exist in first and second subculture extract, omit gradually for the next culture. It was presumed happen caused a different habitat to grow. So it is necessary to enrich the media with queen termite nest to get back the initial metabolites. The enrichment was done using four different media concentrations (0.25; 0,50; 0.75 and 1 grams of nest/mL media). The results show that enrichment of 1 gram of nest/mL media provides the most optimum fungus growht. The third subculture of Aspergillus flavus is cultured on enriched media which will become the fourth subculture, this fungus cultured until tenth subculture, do extraction and fracination to each culture. Based on TLC profile analysis, the initial metabolite not yet formed until tenth subculture, but forms six new stain terpenoid compounds. The result of columns chromatography obtained 10 sub-faction. Activity test was done by diffusion method to 12 test bacteria and 3 test fungus. Spot 2,5,6 (Rf 0.84; 0,36; 0,26) inhibit the growth of Pseudomonas aeruginosa ATCC 27853, spot 3,4 (Rf 0.74; 0,52) inhibit the growth of Micrococcus luteus ATCC 10240. The use of enriched media affect formation of secondary metabolites Aspergillus flavus.

ATR Vowel Harmony: new patterns and diagnostics
Authors: Rose Sharon 
Published: February 2018

This paper presents a large-scale typological study of over 500 Nilo-Saharan and Niger-Congo vowel inventories, both with and without ATR harmony. The survey reveals: i) ATR contrasts in high vowels correlate with a strong likelihood of ATR harmony; ii) the vowel system /i e ɛ a ɔ o u/ (termed 1IU in Casali 2008) does not correlate well with ATR harmony. In Nilo-Saharan, such systems do not show ATR harmony, and in Niger-Congo, the majority of such systems also do not have harmony. The survey results are interpreted in terms of perceptual distance, driven by inventory contrast. High vowel ATR contrasts are perceptually more difficult than mid contrasts and activate harmony. In languages that lack mid vowel contrasts, [+ATR] harmony derives allophonic [e o] from /ɛ ɔ/. In languages that lack high vowel contrasts, mid vowel contrasts do not present enough of a perceptual difficulty to reliably activate harmony. If harmony is present, it tends to operate only between mid vowels and does not generate allophonic high vowels.
Identification and classification of behavioural indicators to assess innovation competence
Authors: Pérez Peñalver María Jose , Aznar Mas Lourdes E. , Montero Fleta Begoña 
Published: February 2018

Purpose: Taking a literature review as a point of departure, the main aim of this paper was the identification of the behavioural indicators of innovators at the workplace, and their classification. Design/methodology/approach: A literature review was addressed by means of a search in Elsevier’s Scopus, Web of Science and Google Scholar. By applying inclusive and exclusive criteria, references were obtained with the search protocol. After filtering and scanning, there was a selection of references plus other articles added by the snowball effect. The final phase undertaken was the classification of the main indicators raised in the publications selected.Findings: Our main contribution was the identification of the behavioural indicators of innovators at the workplace and their classification in five dimensions.Practical implications: This research may yield some light on the assessment of innovative workplace performance of individuals in organisations, as well as on the development of the innovative competence of students in academic institutions as a challenge to meet the needs of both professionals and Higher Education institutions.Originality/value: Some authors have studied the characteristics of innovative people mainly focusing on cognitive abilities, personality, motivation and knowledge. We have sought to offer a better understanding of the phenomenon of individual innovation in organisations, through the analysis of behavioural indicators, an issue that has not been studied from this perspective previously.

Published: February 2018

Abstract
Circulating exosomes containing donor HLA and lung-associated self-antigens (SAg) are thought to play an important role in allograft rejection after human lung transplantation. We characterized exosomes isolated from serum of 10 lung transplant recipients (LTxR) diagnosed with bronchiolitis obliterans syndrome (BOS) and compared them with exosomes isolated from serum of 10 stable LTxR. Lung-associated SAg (K-α-1-tubulin [Kα1T] and collagen V [Col-V]), MHC class II molecules, costimulatory molecules CD40, CD80, and CD86, and transcription factors class II MHC trans-activator, NF-κB, hypoxia-inducible factor 1-α, IL-1R–associated kinase 1, MyD88, and 20S proteasome were detected in exosomes from BOS, but not stable LTxR. In contrast, adhesion molecules were present in both groups. C57BL/6 mice immunized with exosomes from BOS but not stable LTxR demonstrated Ab to SAg (Col-V, 33.5 ± 15.7 versus 10.4 ± 6.4, p = 0.021; Kα1T, 925 ± 403 versus 317 ± 285, p = 0.044) and HLA (mean fluorescence intensity: BOS, 8450; stable, 632; p &lt; 0.05). Furthermore, splenic lymphocytes demonstrated increased frequency of lung SAg-specific IL-17 (Col-V, 128 ± 46 versus 31 ± 21, p = 0.013; Kα1T, 194 ± 47 versus 67 ± 43, p = 0.014) and IFN-γ (Col-V, 165 ± 79 versus 38 ± 40, p = 0.042; Kα1T, 232 ± 64 versus 118 ± 39, p = 0.012). Reduced levels of IL-10–producing cells were seen in BOS exosome immunized mice compared with mice immunized with stable exosomes (Col-V, 59 ± 23 versus 211 ± 85, p = 0.016; Kα1T, 78 ± 49 versus 295 ± 104, p = 0.017). Owing to the unique immune-stimulating properties of exosomes induced during rejection, we propose that they play an important role in eliciting both alloantigen- and SAg-specific immunity, leading to chronic rejection after lung transplantation.

Authors: Mabaso R. G. , Oduntan A. O. 
Published: February 2018

This article reports part of the findings of a study carried out to determine the causes, prevalence, and distribution of ocular dis-orders among rural primary school children in Mopani district of Limpopo Province, South Africa. Three hundred and eighty eight children aged 8 to 15 years were randomly selected from five randomly selected schools. Non-cycloplegic retinoscopy and auto-refrac-tion were performed on each child. The preva-lence of hyperopia, myopia, and astigmatism was 73.1%, 2.5% and 31.3% respectively. Hyperopia (Nearest spherical equivalent power (FNSE) ranged from +0.75 to +3.50 D for the right and left eyes with means of +1.05 ± 0.35 D and +1.08 ± 0.34 D respectively.Myopia (FNSE) ranged from –0.50 to –1.75 D for the right eye and –0.50 to –2.25 D for the left eye with means of –0.75 ± 0.55 D and –0.93 ± 0.55 D respectively. Regression model for myopia, shows that age had an odds ratio of 1.94 (1.15 to 3.26), indicating a significant increased risk of myopia with increasing age. Correcting cylinders for the right eyes ranged from –0.25 to –4.50 D (mean = −0.67 ± 0.47 D) and for the left eyes from –0.25 to –2.50 D (mean = −0.60 ± 0.30 D). With-the-rule (WTR) astigmatism (66.5%) was more common, followed by against-the-rule (ATR)astigmatism (28.1%) and oblique (OBL) astigmatism (5.4%). With-the-rule astigmatism was more common in females than males; ATR astigmatism and OBL astigmatism werecommon in males. Regular vision screening programmes, appropriate referral and vision correction in primary schools in Mopani district are recommended in order to eliminate refractive errors among the children.
Unperforated Pairs of Operator Spaces and Hyperrigidity of Operator Systems
Authors: Clouâtre Raphaël 
Published: February 2018

AbstractWe study restriction and extension properties for states on C*-algebras with an eye towards hyperrigidity of operator systems. We use these ideas to provide supporting evidence for Arveson’s hyperrigidity conjecture. Prompted by various characterizations of hyperrigidity in terms of states, we examine unperforated pairs of self-adjoint subspaces in a C*-algebra. The configuration of the subspaces forming an unperforated pair is in some sense compatible with the order structure of the ambient C*-algebra. We prove that commuting pairs are unperforated and obtain consequences for hyperrigidity. Finally, by exploiting recent advances in the tensor theory of operator systems, we show how the weak expectation property can serve as a flexible relaxation of the notion of unperforated pairs.
Effect of winds and waves on salt intrusion in the Pearl River estuary
Authors: Gong Wenping , Lin Zhongyuan , Chen Yunzhen , Chen Zhaoyun , Zhang Heng 
Published: February 2018

Abstract. Salt intrusion in the Pearl River estuary (PRE) is a dynamic process that is
influenced by a range of factors and to date, few studies have examined the
effects of winds and waves on salt intrusion in the PRE. We investigate these
effects using the Coupled Ocean-Atmosphere-Wave-Sediment
Transport (COAWST) modeling system applied to the PRE. After careful
validation, the model is used for a series of diagnostic simulations. It is
revealed that the local wind considerably strengthens the salt intrusion by
lowering the water level in the eastern part of the estuary and increasing
the bottom landward flow. The remote wind increases the water mixing on the
continental shelf, elevates the water level on the shelf and in the PRE and
pumps saltier shelf water into the estuary by Ekman transport. Enhancement of
the salt intrusion is comparable between the remote and local winds. Waves
decrease the salt intrusion by increasing the water mixing. Sensitivity
analysis shows that the axial down-estuary wind, is most efficient in driving
increases in salt intrusion via wind straining effect.
Calving relation for tidewater glaciers based on detailed stress field analysis
Authors: Mercenier Rémy , Lüthi Martin P. , Vieli Andreas 
Published: February 2018

Abstract. Ocean-terminating glaciers in Arctic regions have undergone rapid
dynamic changes in recent years, which have been related to a dramatic
increase in calving rates. Iceberg calving is a dynamical process
strongly influenced by the geometry at the terminus of tidewater
glaciers. We investigate the effect of varying water level, calving
front slope and basal sliding on the state of stress and flow regime
for an idealized grounded ocean-terminating glacier and scale these
results with ice thickness and velocity. Results show that water depth
and calving front slope strongly affect the stress state while the
effect from spatially uniform variations in basal sliding is much
smaller. An increased relative water level or a reclining calving
front slope strongly decrease the stresses and velocities in the
vicinity of the terminus and hence have a stabilizing effect on the
calving front. We find that surface stress magnitude and distribution
for simple geometries are determined solely by the water depth
relative to ice thickness. Based on this scaled relationship for the
stress peak at the surface, and assuming a critical stress for damage
initiation, we propose a simple and new parametrization for calving
rates for grounded tidewater glaciers that is calibrated with
observations.
