Background: In recent years, a new everbearing strawberry cultivar, ‘Summertiara’ was cultivated to supply the strawberries in pre-harvest season from July to October in Japan. For highly research and development of processing of this cultivar, ‘Summertiara’ berries, the objective of this study was to characterize these berries, with relation to chemical parameters, total phenols, total flavonoids, total vitamin C, and total anthocyanins, and was to investigate the solubility and the stability of anthocyanins from the berries. Moreover, the functional properties such as antioxidative activity, active oxygen species scavenging activity, and antihypertensive activity were also evaluated.Methods: Chemical analysis, colour measurement, and sensory evaluation of new everbearing strawberry cultivar, ‘Summertiara’ berries were performed. Next, the solubility of anthocyanins from the berries and stability of these against pH, temperature, and an incandescent lighting were investigated. Moreover, functional properties of the extracts prepared from berries were elucidated using 5 different methods.Results: The contents of water, proteins, lipids, carbohydrates, and ash were the same as those of other cultivar berries. The sugar-acid ratio in the berries was low; these were acidulous. By sensory evaluation, the main factors were vivid red colour, aroma, and acidity. The berries were rich in phenols, flavonoids, vitamin C, and anthocyanins. The anthocyanins of the berries became unstable by heat treatment and light exposures such as visible rays. On the other hand, the extracts prepared from the berries showed the functionalities such as antioxidant activity, active oxygen species scavenging activities, and antihypertensive activity. Conclusions: The strawberry cultivar, ‘Summertiara’ berries were the most suitable for processing ingredient of strawberry-derived products with superior health promoting functionalities.Keywords: Summertiara, everbearing strawberry cultivar, characterization, sensory evaluation, color and storage, functional property

Pyocyanin is blue pigment redox active, secondary metabolites produced by P. aeruginosa. The present study investigated the bioactivity of pyocyanin against certain types of bacteria and fungi causing human infections
Objectives: Pyocyanin is blue pigment redox active, secondary metabolites produced by P. aeruginosa. The current study deals with biosynthesis, purification and bioactivity of pyocyanin produced by P. aeruginosa.
Design: Pyocyanin extraction was done by chloroform method and concentration was determined by multiplying the optical density at 520 nm by 17.072 expressed as µg/ml. Biological activity of pyocyanin was determined by well diffusion procedure.
Results: According to the source of infection, results showed that P. aeruginosa were most common in ear infection (30%) followed by wounds (22%), burns (17%), urine (13%) and each in stool and diabetes (9%). In this study the high resistance of P. aeruginosa isolates to antibiotics were 19 (82.6 %) to piperacillin followed by 10(43.5%) to aztreonem, 8(34.8%) to meropenem, 6(26.1%) to amikacin, 5(21.7%) to ciprofloxacin then 2(8.7%) to cefotaxime. the urine isolate produced the largest amount of pyocyanin (15.894 µg/ml). pyaocyanin have antimicrobial activity against Pathogenic bacteria: Shigella, Staphyllococcus aureus and Staphyllococcus epidermedis. and pathogenic fungi and yeast: Aspergillus niger, Penicillium spp., Rhizopus spp, Trichophyton mentagrophyte, Rhodotorula spp., Alternaria alternate , Trichophyton rubrum and Candida spp
Conclusions: cefotaxime is the best antibiotic for P. aeruginosa. Antimicrobial activity of pyocyanin against gram positive more than gram negative bacteria but less than that observed against fungi (molds and yeast).

Abstract
Deep near-IR images from the VISTA Variables in the Vía Láctea (VVV) Survey were used to search for RR Lyrae stars within 100 arcmin from the Galactic Center. A large sample of 960 RR Lyrae of type ab (RRab) stars were discovered. A catalog is presented featuring the positions, magnitudes, colors, periods, and amplitudes for the sample, in addition to estimated reddenings, distances, and metallicities, and measured individual relative proper motions. We use the reddening-corrected Wesenheit magnitudes, defined as

, in order to isolate bona fide RRL belonging to the Galaxy Center, finding that 30 RRab are foreground/background objects. We measure a range of extinctions from

to 1.75 mag for the RRab in this region, finding that large extinction is the main cause of the sample incompleteness. The mean period is P = 0.5446 ± 0.0025 days, yielding a mean metallicity of [Fe/H] = −1.30 ± 0.01 (σ = 0.33) dex for the RRab sample in the Galactic Center region. The median distance for the sample is D = 8.05 ± 0.02 kpc. We measure the RRab surface density using the less reddened region sampled here, finding a density of 1000 RRab/sq deg at a projected Galactocentric distance R

G
= 1.6 deg. Under simple assumptions, this implies a large total mass (M > 109
M
⊙) for the old and metal-poor population contained inside R

G
. We also measure accurate relative proper motions, from which we derive tangential velocity dispersions of σV

l
= 125.0 and σV

b
= 124.1 km s−1 along the Galactic longitude and latitude coordinates, respectively. The fact that these quantities are similar indicate that the bulk rotation of the RRab population is negligible, and implies that this population is supported by velocity dispersion. In summary, there are two main conclusions of this study. First, the population as a whole is no different from the outer bulge RRab, predominantly a metal-poor component that is shifted with respect to the Oosterhoff type I population defined by the globular clusters in the halo. Second, the RRab sample, as representative of the old and metal-poor stellar population in the region, has high velocity dispersions and zero rotation, suggesting a formation via dissipational collapse.
Time Variability of Equivalent Width of 6.4 keV Line from the Arches Complex: Reflected X-Rays or Charged Particles?

Published: August 2018

Abstract
Molecular gas in the Arches cloud located near the Arches cluster is one of the emitters of the K-α line of neutral iron and the X-ray continuum in the Galactic center (GC). Similarly to the cloud Sgr B2, another well-known emitter of the iron line in the GC, the Arches cloud demonstrates a temporal decline of the X-ray emission. The most natural origin of this emission is irradiation of primary photons of an X-ray flare from a distant source, most likely Sgr A*. However, recent observations of the Arches cloud discovered variations of equivalent width of the 6.4 keV iron line, which indicated that the X-ray emission from the cloud is a combination of two components with different origins and different equivalent widths, one of which is time variable, while the other is stationary during the period of observations. We considered two different scenarios: (a) this emission is formed by reflection from two clouds, which are at some distance from each other, when they are irradiated by two different flares; and (b) the other scenario assumes a combination of X-ray fluxes produced in the same cloud by reflection of primary photons and by subrelativistic cosmic rays. We present restrictions for both the model and conditions at which these scenarios can be realized. Although none of the models can be completely ruled out, we find that the X-ray reflection model requires fewer assumptions and therefore is the most viable.
Perceptions of Interprofessional and Collaborative Practice in Collegiate Athletic Trainers
Authors: Hankemeier Dorice , Manspeaker Sarah A. 
Published: August 2018

Context:
The ability to engage in interprofessional and collaborative practice (IPCP) has been identified as one of the Institute of Medicine's core competencies required of all health care professionals.

Objective:
To determine the perceptions of athletic trainers (ATs) in the collegiate setting regarding IPCP and current practice patterns.

Design:
Cross-sectional study.

Patients or Other Participants:
Of 6313 ATs in the collegiate setting, 739 (340 men, 397 women, 2 preferred not to answer; clinical experience = 10.97 ± 9.62 years) responded (11.7%).

Main Outcome Measure(s):
The Online Clinician Perspectives of Interprofessional Collaborative Practice survey section 1 assessed ATs' perceptions of working with other professionals (construct 1), ATs engaged in collaborative practice (construct 2), influences of collaborative practice (construct 3), and influences on roles, responsibilities, and autonomy in collaborative practice (construct 4). Section 2 assessed current practice patterns of ATs providing patient care and included the effect of communication on collaborative practice (construct 5) and patient involvement in collaborative practice (construct 6). Between-groups differences were assessed using a Kruskal-Wallis H test and Mann-Whitney U tests (P &lt; .05).

Results:
Athletic trainers in the collegiate setting agreed with IPCP constructs 1 through 4 (construct 1 = 3.56 ± 0.30, construct 2 = 3.36 ± 0.467, construct 3 = 3.48 ± 0.39, construct 4 = 3.20 ± 0.35) and indicated that the concepts of constructs 5 and 6 (1.99 ± 0.46, 1.80 ± 0.50, respectively) were sometimes true in their setting. Athletic trainers functioning in a medical model reported lower scores for construct 5 (1.88 ± 0.44) than did those in an athletic model (2.03 ± 0.45, U = 19 522.0, P = .001). A total of 42.09% of the ATs' patient care was performed in collaborative practice.

Conclusions:
Athletic trainers in the collegiate setting agreed that IPCP concepts were beneficial to patient care but were not consistently practicing in this manner. Consideration of a medical model structure, wherein more regular interaction with other health care professionals occurs, may be beneficial to increase the frequency of IPCP.
Relationships between impulse oscillometry, spirometry and dyspnoea in COPD
Authors: Anderson WJ , Lipworth BJ 
Published: August 2018

Background: Severity of chronic obstructive pulmonary disease (COPD) is based either on symptoms/disability or lung function, which have no discernible correlation. We hypothesised that impulse oscillometry (IOS), a non-effortdependent measure of central and peripheral airway mechanics, could correlate to dyspnoea in COPD. Methods: We analysed screening data from 57 COPD patients who had spirometry, IOS and Medical Research Council dyspnoea score (MRC) measurements. We searched for predictors or correlations of MRC from IOS, spirometry and demographics. Results: MRC had no significant predictors or correlations from IOS, spirometry or demographics (possibly excepting smoking history, p=0.05). IOS correlated significantly with spirometry: FEV1 and FEF25–75 vs. R5–R20 (peripheral airway resistance), r=–0.499, p<0.001 and r=–0.397, p=0.002 respectively. Conclusion: MRC is not related to IOS or spirometry in COPD. IOS correlates well with spirometry, particularly peripheral airway resistance (R5–R20). IOS is useful, but does not provide a link between symptoms and pulmonary function measurements.
Assessing frailty in the acute medical admission of elderly patients
Authors: Oo MT , Tencheva A , Khalid N , Chan YP , Ho SF 
Published: August 2018

Background: Managing acute admission of frail older patients is a challenge in hospitals. Length of inpatient stay, inpatient mortality and the 90-day readmission rate are significant in this group of patients. The Comprehensive Geriatric Assessment (CGA), a multidisciplinary diagnostic and treatment process, is the best approach for identifying medical conditions, mental health, functional capacity and social circumstances in acute geriatric care. Methods: A review of the records of older patients aged 75 and over, acutely admitted to a district general hospital in England from 15 March 2012 to 16 April 2012 was conducted. We developed a frailty assessment tool and applied it to these patients, in order to determine who would be classified as frail. We then established if the patients meeting this criteria were then correctly assessed using the CGA. All patient data were processed and analysed using a statistical package for data analysis. Results: A total of 232 patients with a mean age of 84.25 ± 5.8 years were included. Out of these, 129 patients (55.6%) fulfilled the frailty criteria as determined with our frailty-assessment tool; 80.6% presented with lack of mobility over 24 hours, 69.8% were admitted with falls, 47.3% had known dementia or delirium and 45% were admitted from care homes. Patients aged over 85 years were more likely to have frailty compared with patients aged 75–85 years old (odds ratio [OR]: 4.78, 95% confidence interval [CI]: 2.6–8.6, p value <0.001). Patients assessed by a front door geriatric team were more likely to be reviewed with the CGA than those not seen by this team (adjusted OR 2.8, 95% CI: 1–7.6, p value=0.04). Conclusion: The prevalence of frailty is high in acute admissions of older patients and it is important that they are properly identified and assessed with a CGA in order to ensure effective multidisciplinary care.
Imprint of Southern Ocean mesoscale eddies on chlorophyll
Authors: Frenger Ivy , Münnich Matthias , Gruber Nicolas 
Published: August 2018

Abstract. Although mesoscale ocean eddies are ubiquitous in the Southern Ocean, their
average regional and seasonal association with phytoplankton has not been
quantified systematically yet. To this end, we identify over 100 000
mesoscale eddies with diameters of 50 km and more in the Southern Ocean and
determine the associated phytoplankton biomass anomalies using
satellite-based chlorophyll-a (Chl) as a proxy. The mean Chl anomalies,
δChl, associated with these eddies, comprising the upper echelon of
the oceanic mesoscale, exceed ±10 % over wide regions. The structure of
these anomalies is largely zonal, with cyclonic, thermocline lifted, eddies
having positive anomalies in the subtropical waters north of the Antarctic
Circumpolar Current (ACC) and negative anomalies along its main flow path.
The pattern is similar, but reversed for anticyclonic, thermocline deepened
eddies. The seasonality of δChl is weak in subtropical waters, but
pronounced along the ACC, featuring a seasonal sign switch. The spatial
structure and seasonality of the mesoscale δChl can be explained
largely by lateral advection, especially local eddy-stirring. A
prominent exception is the ACC region in winter, where δChl is
consistent with a modulation of phytoplankton light exposure caused by an
eddy-induced modification of the mixed layer depth. The clear impact of
mesoscale eddies on phytoplankton may implicate a downstream effect on
Southern Ocean biogeochemical properties, such as mode water nutrient
contents.
Isoprene-derived secondary organic aerosol in the global aerosol–chemistry–climate model ECHAM6.3.0–HAM2.3–MOZ1.0
Authors: Stadtler Scarlet , Kühn Thomas , Schröder Sabine , Taraborrelli Domenico , Schultz Martin G. , Kokkola Harri 
Published: August 2018

Abstract. Within the framework of the global chemistry climate model
ECHAM–HAMMOZ, a novel explicit coupling between the sectional aerosol model
HAM-SALSA and the chemistry model MOZ was established to form isoprene-derived secondary organic aerosol (iSOA). Isoprene oxidation in the chemistry
model MOZ is described by a semi-explicit scheme consisting of 147 reactions
embedded in a detailed atmospheric chemical mechanism with a total of
779 reactions. Semi-volatile and low-volatile compounds produced during
isoprene photooxidation are identified and explicitly partitioned by
HAM-SALSA. A group contribution method was used to estimate their evaporation
enthalpies and corresponding saturation vapor pressures, which are used by
HAM-SALSA to calculate the saturation concentration of each iSOA precursor.
With this method, every single precursor is tracked in terms of condensation
and evaporation in each aerosol size bin. This approach led to the
identification of dihydroxy dihydroperoxide (ISOP(OOH)2) as a main
contributor to iSOA formation. Further, the reactive uptake of isoprene
epoxydiols (IEPOXs) and isoprene-derived glyoxal were included as iSOA
sources. The parameterization of IEPOX reactive uptake includes a dependency
on aerosol pH value. This model framework connecting semi-explicit isoprene
oxidation with explicit treatment of aerosol tracers leads to a global
annual average isoprene SOA yield of 15 % relative to the primary
oxidation of isoprene by OH, NO3 and ozone. With 445.1 Tg
(392.1 Tg C) isoprene emitted, an iSOA source of 138.5 Tg (56.7 Tg C) is
simulated. The major part of iSOA in ECHAM–HAMMOZ is produced by IEPOX
at 42.4 Tg (21.0 Tg C) and ISOP(OOH)2 at 78.0 Tg (27.9 Tg C). The main sink
process is particle wet deposition, which removes 133.6 (54.7 Tg C). The
average iSOA burden reaches 1.4 Tg (0.6 Tg C) in the year 2012.
Assessment of Indigenous N, P and K Supply for Rice Site Specific Nutrient Management in Buru Regency
Authors: Susanto Andriko Noto , Sirappa Marthen Pasang 
Published: August 2018

Rate of fertilizer that should be applied to rice soil based on Site Specific Nutrient Management (SSNM) depends on indigenous nutrient supply, its recovery efficiency, and the amount of nutrients requirement to achieve the yield target. Research on nutrient omission plot was conducted in farmers irrigated land on Waeapo plain, Buru Island. In this area, N, P, and K were the main limiting factors of rice growth and yield. To overcome the constraint, this assessment was conducted to determine the indigenous supply of N, P and K and optimal target of rice productivity. Results of this assessment showed that the average of rice optimum productivity (Mg grain water content/w.c. 14% ha-1) in Waeapo plain was 6.55 Mg DGM (Dry Grain Milled) ha-1, with range from 5.6 to 7.3 Mg DGM ha-1 depended on the indigenous supply of N, P and K. The average value of the indigenous N, P and K supplies in Waeapo plain Buru was 65.59 kg N ha-1, 13.70 kg P ha-1 and 78.65 kg K ha-1, respectively while average productivity of rice on that indigenous N, P and K supplies was 5.05, 5.96 and 6.05Mg DGM ha-1, respectively. The value of indigenous nutrient supply of this nutrient can be used as a basis of fertilizer recommendation with the SSNM concept.

The Animacy Advantage in Memory: Manipulations of Levels of Processing and Survival Processing
Authors: Leding Juliana K. 
Published: August 2018

Abstract
Two experiments were conducted to explore the animacy advantage in memory, which has shown that words for animate objects are more likely to be remembered than words for inanimate objects. In the first experiment, participants processed words for animate and inanimate objects either shallowly (i.e., by indicating whether each word contained an “e”) or deeply (i.e., by rating the pleasantness of the items). In the second experiment, participants rated the relevance of the study items to either a moving scenario or to a grasslands survival scenario. As expected, in the first experiment the deep processing led to higher rates of recall, and in the second experiment the grasslands survival scenario led to higher rates of recall. In both experiments, animate words were recalled at a significantly higher rate than inanimate words regardless of processing condition. The data from these experiments provide more evidence for the animacy advantage in memory, which supports the adaptive memory view.
Demonstrating Conceptual Clustering in Autobiographical Memory with Voluntary Recall Tasks: More Evidence for the Conceptual Organization View
Authors: Mace John H. , Hall Austin J. 
Published: August 2018

Abstract
Research on the nature of episodic memory organization has suggested that the dominant organizing principle among episodic memories is either conceptual organization, where memories cluster around the same content (e.g., memories about the people), or a type of temporal organization known as general events, where memories cluster around extended events (e.g., a holiday in London), repeated events (e.g., Sunday walks in the park), or causally related events (i.e., where one event leads to another). Because these opposing conclusions have been derived separately from involuntary or voluntary measures of autobiographical memory, Mace, Clevinger, and Martin (2010) hypothesized that involuntary retrieval processes and voluntary retrieval processes may be accessing episodic memories differentially, such that one produces high frequencies of conceptually clustered memories, whereas the other produces high frequencies of general event clustered memories. This study failed to find support for this hypothesis. In 2 experiments, 3 different types of voluntary retrieval tasks found that conceptually clustered memories were substantially more frequent than general event clustered memories. We argue that these results support the view that episodic memories are organized mainly conceptually.

Sobre narrar a experiência e o outro: os riscos da xenía em "Meu Tio o Iauaretê"
Authors: Lopes da Costa Lorena 
Published: August 2018

O presente artigo busca discutir alguns aspectos da xenía [hospitalidade] e os desafios concernentes à tarefa do historiador, aqui entendido como xénos [hóspede/ anfitrião/ estrangeiro]. Nesta oportunidade, tendo então como objeto o conto "Meu tio o Iauaretê" de João Guimarães Rosa, privilegio observar os riscos da relação de hospitalidade que rondam a condição de ser xénos, tanto do anfitrião de um estrangeiro desconhecido quanto do estrangeiro na casa de um anfitrião desconhecido. Reflito também sobre a ameaça a que está sujeita a apreensão da experiência da xenía por parte dos xénoi, e, assim, a que está sujeito o retorno do estrangeiro. Palavras-chave: Historiador.
