Abstract
Rice is a food source of carbohydrate which is a staple food in Indonesia. One way to increase production is to control soil productivity by using organic and inorganic fertilizers. This research was conducted to determine the effect of organic fertilizer combined with N, P, K inorganic fertilizers on the chemical properties and growth of rice plants. This research was conducted from June-September 2018. The experimental design was carried out using a Randomized Block Design (RBD) consisting of 10 treatments with three replications. The treatment combination consisted of liquid organic fertilizer dosages of 0 ml / L, 2.5 ml / L, 5 ml / L 7.5 ml / L and 10 ml / L and inorganic fertilizer N doses of 0 kg / ha, 50 kg / ha, 100 kg / ha, 150 kg / ha 200 kg / ha. inorganic P 0 kg / ha, 37.5 kg / ha, 75 kg / ha, 112.5 kg / ha, 150 kg / ha inorganic K 0 kg / ha, 12.5 kg / ha, 25 kg / ha, 37.5 kg / ha 50 kg / ha. The results showed that the combination of organic and inorganic fertilizers N, P, K did not influence the soil chemical properties and plant growth. The highest yields on plant height after 8 WAP were shown in treatment D (1 dose of LOF + 1 N, P, K) with 58.03 cm.

Abstract
This research aimed to develop image processing program to extract several features of Siamese orange images and to determine the appropriate key features of the orange images which were highly correlated with physical and chemical characteristics of Siamese orange. A sample size of 210 oranges was stored in a room temperature (25-27 °C) and cold temperature (8-10 °C) for 30 days. All oranges were captured their images using a webcam and were subsequently measured their physical and chemical characteristics, i.e. weight, hardness, and total soluble solids (TSS). The visual parameters of images measured were binary area in pixels, RGB color, HSV color, CIE-Lab color and gray value. The results showed that there was a high correlation between fruit weight and binary area in both room and cold temperature storage with r2= 0.8197 and r2= 0.8291, respectively. On the other hand, color values cannot be used to estimate fruit hardness since the correlation coefficient was too small. The highest correlation coefficient between them was r= 0.114 which was achieved from the correlation between fruit hardness and hue value. The r value of TSS and some color components was nevertheless relatively strong. Based on the experiments, hue value of HSV color model and a* component of CIE-Lab color model have fairly strong correlations with TSS of oranges stored in room temperature which were indicated from the lvalue of 0.7473 and 0.7029,respectively.

AbstractCurrently, several problems raised from the frequent application of chemical insecticide for dengue control such as insecticide resistance and environmental health issues. This fact supporting the need for the alternative active ingredients which are natural and could not develop insecticide resistance. This study aims to find out the potential of Pyrethrum (Chrysanthemum cinerariifolium (Trevir.) Vi) and Neem (Azadirachta indica A. Juss) as biolarvacide against Aedes aegypti. This study used a quasi-experimental study using several combinations of Pyrethrum and Neem extracts. The larvae test used 25 larvae for every combination. Three repetitions applied for each treatment. Larval deaths were observed every hour until 24 hours, and several dead larvae were calculated. Results of this study showed that almost all formulations caused death of larvae in the first hour except formulation 5 (2 ml Pyrethrum + 1 ml DMSO + 24 ml liquid paraffin + 24 ml chitin), formulation 8 (49 ml neem + 1 ml Tween 20) and formulation 11 (49 ml neem + 1 ml DMSO). These results emphasised the potential of a formulation containing Pyrethrum and neem as biolarvacide against Aedes aegypti…. (Introduction, methods, results, discussion, conclusion)

Abstract
Inulinase is an enzyme that catalyzes inulin to produce D-fructose as the end product which is considered as safe alternative sweetener to sucrose. This enzyme can be extracted from plants and vegetables but it is difficult to obtain it in high quantity and the production cost also high. The main problem in utilizing this enzyme in industrial is the instability against fluctuation of temperature that usually occurs in industrial process. Therefore thermophilic microbial inulinase has great potential for these industrial needs. The aim of this study was to isolate and characterize the thermophilic bacteria that possess the inulinase activity from hot springs in Penen Village, North Sumatera. To screening the inulinase producing bacteria, the modified Czapex Dox agar supplemented with 1,5% inulin powder was used. The temperature used for incubation is 48 °C. The clear zone surrounds the bacteria after Lugol’s iodine treatment on medium indicated the nucleolytic activity. As 4 isolates of thermophilic bacteria namely UTMP 11, UTMP 14, UTMP 15 and UTMP 17 showed the inulolytic activity. The biochemical characterization of these isolates showed negative in catalase test, negative on citrate test, non-motil, negative Gram staining, and rod-shaped morphology. Molecularly, this bacteria identified as Bacillus subtilis strain JCM 1465 and Bacillus tequilensis strain 10b. From the result, these isolates have potential as source of thermophilic inulinase production in food industry for the production of fructose.

Published: December 2019

Abstract
Indonesia’s sago industry yielded around 400 thousand tons per year, which was the second largest producer in the world. The Weaknesses of Indonesiansago, in term of its quality, included a brownish color, unpleasant odor and soft texture. All of those characteristics can be corrected by addition of Laccase enzyme. Wet sago still contains natural microbes that can be used as a source of beneficial germplasm of bacteria and fungi. In this study, conventional method for isolating bacteria was performed. Conventional isolation technique obtained 26 isolates from sago. It, then, followed by biochemical analysis to obtain 5 isolates of putative bacteria candidate for bioleaching. The sequencing result indicated 3 potential bacteria, which generate laccase enzymes, namely Lactobacillus plantarum (2) and Lactobacillus brevis (1). Isolated bacteria, then, were fermented in the 500 mL flask and followed with laccase activity analysis with adding guaiacol as substrate and read using spectrophotometer, resulted in 64 U/L, 54 U/L, and 202 U/L, respectively. In conclusion, Laccase enzyme, produced from food grade endogenous sago species, might likely improve the quality of sago starch, which leads to increase the broader utilization of sago starch.

Published: December 2019

AbstractPhylogenomics is progressing rapidly, allowing large strides forward into our understanding of the tree of life. In this study, we generated transcriptomes from ethanol-preserved specimens of 13 tiger beetle species (Coleoptera: Cicindelinae) and one Scaritinae outgroup. From these 14 transcriptomes and seven publicly available transcriptomes, we recovered an average of 2538 loci for phylogenetic analysis. We constructed an evolutionary tree of tiger beetles to examine deep-level relationships and examined the extent to which the composition of the dataset, missing data, gene tree inconsistency and codon position saturation impacted phylogenetic accuracy. Ethanol-preserved specimens yielded similar numbers of loci to specimens originally preserved in costly reagents, showcasing more flexibility in transcriptomics than anticipated. The number of loci and gene tree inconsistency had less impact on downstream results than third codon position saturation and missing data. Our results recovered tiger beetles as sister to Carabidae with strong support, confirming their taxonomic status as an independent family within Adephaga. Within tiger beetles, phylogenetic relationships were robust across all nodes. This new phylogenomic backbone represents a useful framework for future endeavours in tiger beetle systematics and serves as a starting point for the development of less costly target capture toolkits to expand the taxonomic breadth of the future tiger beetle tree of life.
Cross-Cultural Social Work: A Critical Approach to Teaching and Learning to Work Effectively across Intersectional Identities
Authors: Azzopardi Corry 
Published: December 2019

AbstractAll relationships in social work education and practice constitute sites of cross-cultural exchanges. In keeping with the profession’s social justice mandate and anti-oppressive principles, it is fundamental for emerging social workers to begin the life-long learning process of developing a congruent composite of awareness, values, knowledge and skills essential for working effectively across diverse social locations and intersectional identities. Grounded in a social justice framework, this article engages critically with the concept of cultural competence in social work pedagogy, explores the significance of diversity and intersectionality in social work education and proposes a multidimensional model for teaching, learning and evaluating cross-cultural sensitivity and responsivity in the social work class-room.
Characterization and engineering of S100A12–heparan sulfate interactions

Published: December 2019

AbstractS100A12, an EF-hand calcium-binding protein, can be secreted by a variety of cell types and plays proinflammatory roles in a number of pathological conditions. Although S100A12 has been shown to interact with heparan sulfate (HS), the molecular detail of the interaction remains unclear. Here we investigate the structural basis of S100A12–HS interaction and how the interaction is regulated by the availability of divalent cations and the oligomeric states of S100A12. We discovered that S100A12–HS interaction requires calcium, while zinc can further enhance binding by inducing S100A12 hexamerization. In contrast, the apo form and zinc-induced tetramer form were unable to bind HS. Guided by the crystal structures of S100A12, we have identified the HS-binding site of S100A12 by site-directed mutagenesis. Characterization of the HS-binding site of S100A12 allowed us to convert the non-HS-binding apo and tetramer forms of S100A12 into a high affinity HS-binding variant by engineering a single-point mutation. Using a HS oligosaccharide microarray, we demonstrated that the N43K mutant displayed markedly enhanced selectivity toward longer HS oligosaccharides compared to the WT S100A12, likely due to the expanded dimension of the reengineered HS-binding site in the mutant. This unexpected finding strongly suggests that HS-binding sites of proteins might be amenable for engineering.

Published: December 2019

Abstract

Background
Obesity (OB) is a serious epidemic in the United States.

Methods
We examined OB patterns and time trends across socio-economic and geographic parameters and projected the future situation. Large national databases were used. Overweight (OW), OB and severe obesity (SOB) were defined using body mass index cut-points/percentiles; central obesity (CO), waist circumference cut-point in adults and waist:height ratio cutoff in youth. Various meta-regression analysis models were fit for projection analyses.

Results
OB prevalence had consistently risen since 1999 and considerable differences existed across groups and regions. Among adults, men’s OB (33.7%) and OW (71.6%) levelled off in 2009–2012, resuming the increase to 38.0 and 74.7% in 2015–2016, respectively. Women showed an uninterrupted increase in OB/OW prevalence since 1999, reaching 41.5% (OB) and 68.9% (OW) in 2015–2016. SOB levelled off in 2013–2016 (men: 5.5–5.6%; women: 9.7–9.5%), after annual increases of 0.2% between 1999 and 2012. Non-Hispanic Blacks had the highest prevalence in women’s OB/SOB and men’s SOB. OB prevalence in boys rose continuously to 20.6% and SOB to 7.5% in 2015–2016, but not in girls. By 2030, most Americans will be OB/OW and nearly 50% of adults OB, whereas ∼33% of children aged 6–11 and ∼50% of adolescents aged 12–19 will be OB/OW. Since 1999, CO has risen steadily, and by 2030 is projected to reach 55.6% in men, 80.0% in women, 47.6% among girls and 38.9% among boys. Regional differences exist in adult OB prevalence (2011–2016) and across ethnicities; South (32.0%) and Midwest (31.4%) had the highest rates.

Conclusions
US obesity prevalence has been rising, despite a temporary pause in 2009–2012. Wide disparities across groups and geographical regions persist. Effective, sustainable, culturally-tailored interventions are needed.
Scale-invariant dynamics of galaxies, MOND, dark matter, and the dwarf spheroidals
Authors: Maeder Andre , Gueorguiev Vesselin G 
Published: December 2019

ABSTRACT
The Scale-Invariant Vacuum (SIV) theory is based on Weyl’s Integrable Geometry, endowed with a gauge scalar field. The main difference between MOND and the SIV theory is that the first considers a global dilatation invariance of space and time, where the scale factor λ is a constant, while the second opens the likely possibility that λ is a function of time. The key equations of the SIV framework are used here to study the relationship between the Newtonian gravitational acceleration due to baryonic matter gbar and the observed kinematical acceleration gobs. The relationship is applied to galactic systems of the same age where the radial acceleration relation (RAR), between the gobs and gbar accelerations, can be compared with observational data. The SIV theory shows an excellent agreement with observations and with MOND for baryonic gravities gbar &gt; 10−11.5 m s−2. Below this value, SIV still fully agrees with the observations, as well as with the horizontal asymptote of the RAR for dwarf spheroidals, while this is not the case for MOND. These results support the view that there is no need for dark matter and that the RAR and related dynamical properties of galaxies can be interpreted by a modification of gravitation.
Violent buckling benefits galactic bars
Authors: Collier Angela 
Published: December 2019

ABSTRACT
Galactic bars are unstable to a vertical buckling instability which heats the disc and in some cases forms a boxy/peanut shaped bulge. We analyse the buckling instability as an application of classical Euler buckling followed by non-linear gravitational Landau damping in the collisionless system. We find that the buckling instability is dictated by the kinematic properties and geometry of the bar. The analytical result is compared to simulations of isolated galaxies containing the disc and dark matter components. Our results demonstrate that violent buckling does not destroy bars while a less energetic buckling can dissolve the bar. The discs that undergo gentle buckling remain stable to bar formation which may explain the observed bar fraction in the local Universe. Our results align with the results from recent surveys.
Integrating Music Therapy Students into Interprofessional Education: Academic Program Development
Authors: Meadows Anthony , Schempp Anne , Landless Bronwen 
Published: December 2019

Abstract
Interprofessional education (IPE) occurs when students from two or more professions associated with health or social care engage in learning with, from, and about each other. IPE addresses four essential competencies that not only seek to prepare students for interprofessional practice, but also strive to improve the overall quality of healthcare delivery for patients and their families. This article describes the development of an IPE program that fully integrates music therapy students into program-wide and program-to-program IPE events. We identify core components of IPE, describe the development of program-wide and program-to-program events involving undergraduate and graduate music therapy students, and discuss the benefits and challenges encountered during program development. In doing so, we advocate for IPE as a core component of music therapy education and training.
Risks and Safety of Extended Auricular Therapy: A Review of Reviews and Case Reports of Adverse Events
Authors: Nielsen Arya , Gereau Sezelle , Tick Heather 
Published: December 2019

AbstractObjectiveAuricular acupuncture (AA) and extended auricular therapy (AT) are a part of acupuncture practice shown to benefit patients with pain, anxiety, and other conditions, with cost-effective access enhanced when given in a group setting. Yet there are safety concerns and risks, perhaps unnecessary risks, that attend embedded, indwelling needles applied to the ear as a means of extended AT.MethodsElectronic searches were conducted in PubMed, MEDLINE, CINAHL and Cochrane Central Register of Controlled Trials (CENTRAL) for “auriculotherapy,” “auricular acupuncture” or “auricular acupressure,” “safety,” “adverse events,” “chondritis,” and “perichondritis,” with additional manual review of titles, links, and reference lists. Individual auricular therapy adverse event (AE) case reports were included, as well as systematic reviews and or meta-analyses if they evaluated AEs associated with AT.ResultsNineteen auricular AE case reports and nine safety reviews of or including auriculotherapy were included. Ten systematic reviews of AT with eight specific reviews of auricular acupressure (AP) were also included.ConclusionsThe primary AE risks is infection, perichondritis, and chondritis stemming from embedded or indwelling needles or potential inadvertent needlesticks from contaminated roaming sharps. Extended AP i.e., application of spheres, preferably seeds (natural, nontoxic botanical Vaccaria seeds) provides clinical benefit without the risks associated with embedded needles. More research is needed to establish if embedded needles at the ear are even necessary or have any advantage over in-session auricular acupuncture for immediate pain relief followed by ear acupressure.
