Published: September 2019

Enceng gondok merupakan tanaman pengganggu dalam ekosistem air karena pertumbuhannya yang sangat cepat sehingga perlu dipikirkan cara untuk pemusnahan tanaman ini. Namun enceng gondok merupakan biomassa yang mempunyai kandungan hemiselulosa, selulosa dan lignin yang tinggi. Pirolisis adalah metode yang tepat untuk mengubah biomassa yang diproses secara termal menjadi produk yang bernilai. Pirolisis merupakan proses degradasi termal untuk mengahasilkan bio-char, bio-oil dan bio-gas tanpa adanya oksigen. Tujuan penelitian ini adalah untuk mencari suhu optimum dari proses pirolisis dan mencari parameter kinetika untuk membantu peneliti dalam merancang reaktor dan memahami reaksi yang terjadi. Model yang diusulkan untuk mempresentasikan reaksi pirolisis enceng gondok adalah Compatting model. Hasil dari penelitian ini menunjukkan bahwa suhu 600°C merupakan suhu optimum untuk mengahasilkan bio-oil. Dengan menggunakan program matlab konstanta kinetika reaksi pada pembentukan gas pada proses pirolisis enceng gondok adalah  k1=3,4997exp-14069,21/RTmen-1,  konstanta kinetika reaksi pembentukan bio-oil adalah k2=0,3430exp-3059,451/RTmen-1  dan konstanta kinetika reaksi pembentukan char adalah k3=0,2526 exp-2313,395/RT men-1.
A systematic review of interventions for supporting partners of military Veterans with PTSD
Authors: Turgoose David , Murphy Dominic
Published: September 2019

Introduction: Partners of military Veterans with post-traumatic stress disorder (PTSD) and other mental health difficulties can themselves develop difficulties with stress, well-being, and secondary trauma. Various interventions exist which involve partners of military personnel, but very few with an explicit focus on the partners’ well-being. This article aims to conduct a systematic review of these interventions and outline the range of interventions and the outcomes measured. Methods: We conducted a systematic literature search, from which 25 papers were reviewed. Papers were included if they described any form of intervention in which a partner was involved, where the Veteran was described as having PTSD, and where the aim of the intervention was aimed at least partly at improving the well-being of partners. Results: We found various types of interventions, such as group-based interventions, residential retreats, couples therapies, Internet-based interventions, and family-based interventions. Of the 25 studies reviewed, 21 reported on well-being outcomes, either via randomized controlled trials (RCTs), evaluations, or case studies. In most cases, interventions reported improvements in the well-being of partners, although there were very few controlled studies. Only a small number of interventions were aimed solely at partners. The most common feature of interventions was psychoeducation on topics such as communication, problem solving, and emotion regulation. Many papers described the advantages of group processes such as social support and normalization, gained from partners sharing experiences with one another. Discussion: A wide range of formats exist of interventions for improving the well-being of military partners. The literature would benefit from more robust experimental research into their effectiveness, and exploration of interventions aimed directly at the well-being of partners.

Published: September 2019

Introduction: Medical use of ionizing radiation has direct/indirect undesirable effects on normal tissues. In this study, the radioprotective effect of arbutin in megavoltage therapeutic x-irradiated mice was investigated using serum alkaline phosphatase (ALP), alanine aminotransferase (ALT), and asparate amniotransferase (AST) activity measurements.Material and Methods: In this analytical and experimental lab study, sixty mice (12 identical groups) were irradiated with 6 MV x-ray beam (2 and 4 Gy in one fraction). Arbutin concentrations were chosen 50, 100, and 200 mg/kg and injected intraperitoneal 2 hours before irradiation. Samples of peripheral blood cells were collected and serum was separated on the 1, 3, and 7 days post-x-radiation; in addition, the level of ALP, ALT, and AST were measured. Data were analyzed using one-way ANOVA, and Tukey HSD test.Results: X-radiation (2 and 4 Gy) increased the ALT and AST activity levels on the 1, 3, and 7 days post- irradiation, but the ALP level significantly increased on the 1 and 7 days and decreased on the third day compared to the control group (P< 0.001). ALP, ALT and AST activity levels in “2 and 4 Gy x irradiation + distilled water” groups were significantly higher than “2 and 4 Gy irradiation + 50, 100, and 200 mg/kg arbutin” groups on the first and seventh day post-irradiation (P< 0.001).Conclusion: Arbutin is a strong radioprotector for reducing the radiation effect on the whole-body tissues by measuring ALP, ALT and AST enzyme activity levels. Furthermore, the concentration of 50 mg/kg arbutin showed higher radioprotective effect.

Published: September 2019

The development of online peer-to-peer lending is in full bloom due to the support of network technology and information technology. More and more people are keen to participate in them. Online P2P lending platforms provide services where investors lend money to borrowers without the involvement of traditional financial institutions. Due to its convenience, the platforms have attracted many investors and borrowers. However, these investors may suffer a significant loss if they cannot make better borrowing decisions based on prediction credit risk. The purpose of this article is to study the relationship between successful borrowing times (SBT) and successful loans and default loans. This article further explores SBT plays an importance of the role in online P2P lending. Data was collected from PaiPaiDai, an online P2P lending platform in China. Logistic modeling was employed to test the proposed hypotheses. The results show that the probability of default loan by borrowers with more SBT is low, and the probability of successful loan is higher. It shows that investors are more willing to choose borrowers with more SBT. The investors can effectively recognize the value of SBT in the transaction process, and can identify credit risk through SBT in the online P2P lending market. SBT can predict credit risk, which suggests the proposed method has favorable potential being implemented in real-world P2P lending platforms.
The Added Value of Cardiac Magnetic Resonance in Muscular Dystrophies
Authors: Lamacie Mariana M. , Warman-Chardon Jodi , Crean Andrew M. , Florian Anca , Wahbi Karim
Published: September 2019

Muscular dystrophies (MD) represent a heterogeneous group of rare genetic diseases that often lead to significant weakness due to progressive muscle degeneration. In many forms of MD, cardiac manifestations including heart failure, atrial and ventricular arrhythmias and conduction abnormalities can occur and may be a predominant feature of the disease. Cardiac magnetic resonance (CMR) can assess cardiac anatomy, global and regional ventricular function, volumes and mass as well as presence of myocardial inflammation, infiltration or fibrosis. The role for cardiac MRI has been well-established in a wide range of muscular dystrophies related cardiomyopathies. CMR is a more sensitive technique than echocardiography for early diagnosis of cardiac involvement. It has also great potential to improve the prediction of long-term outcome, particularly the development of heart failure and arrhythmic events; however it still has to be validated by longitudinal studies including large populations. This review will outline the utility of CMR in patients with muscular dystrophies for assessment of myocardial involvement, risk stratification, and in guiding therapeutic management.

Published: September 2019

BACKGROUND:

Patients treated in psychiatric care are exposed to the risk of adverse events, similar to patients treated in somatic health care.

OBJECTIVES:

In this article we report the findings of triggers associated with adverse events (AEs) identified by a version of the Global Trigger Tool – Psychiatry (GTT-P) adapted for Norwegian hospital-based psychiatric treatment.

METHODS:

The design was a retrospective analysis of a random sample of 240 patient records from a psychiatric clinic in one Norwegian hospital. Patient records were sampled from both inpatient and outpatient psychiatric clinics in hospitals serving the northern part of the county of Trøndelag, Norway.

RESULTS:

Our analysis was based on the identification of 32 potential triggers of adverse events. Eighteen of the triggers were significantly related to adverse events. No adverse events were identified in patient records that did not also contain triggers included in the Global Trigger Tool.

CONCLUSIONS:

There is a clear relationship between the presence of triggers in a patient record and the likelihood of adverse events. Particularly relevant for psychiatric patients is ‘suffering’ as a trigger and this may also be relevant to somatic care and has implications for inclusion in the GTT-P.

Published: September 2019

OBJECTIVE:

Since cancer treatment and outcome differ among the patients diagnosed with breast cancer at different stages, this study aims to elucidate the factors associated with PET/CT staging, treatment effect, and maximal standardized uptake value (SUVmax) in breast cancer patients.

METHODS:

Twenty-eight patients who underwent two PET/CT examinations with the complete pathological and immunohistochemical data were retrospectively reviewed. Pearson and Spearman correlation analyses were performed to investigate the relationships of patient PET/CT staging (first round PET/CT), treatment effect (comparison between the results of two rounds of PET/CT), and tumor SUVmax, with respect to patient age, tumor location, tumor long diameter, short diameter, time of first round PET/CT examination, histological type and grade, axillary lymph node metastasis rate, interval between the two PET/CT examinations, treatment method, and the expression of the estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor 2 (HER2), P53, and Ki67.

RESULTS:

PET/CT staging (first round PET/CT) relates to HER2 and Ki67 expression with the correlation coefficients of 0.432 and 0.552, and P-values of 0.022 and 0.002, respectively. The treatment effect (comparison between the results of two rounds of PET/CT) associates with tumor site and P53 expression in which the correlation coefficients are – 0.412 and 0.845, and P-values are 0.029 and 0.000, respectively. The measured SUVmax correlates well with the tumor long diameter, short diameter, and treatment effect in which the correlation coefficients are 0.943, 0.886, and 0.878, and P-values are 0.005, 0.019, and 0.02, respectively.

CONCLUSIONS:

Study results indicate that PET/CT staging and treatment effect associate well with SUVmax and immunohistochemical results of tumor, while SUVmax of tumor associates well with tumor size.

Genetic Variability of Tef [Eragrostis Tef (Zucc.) Trotter] Genotypes for Acid Soil Tolerance
Authors: Merga Misgana , Mohammed Hussein , Assef Kebebew
Published: September 2019

Genetic variability studies provide basic information for breeders to develop different stress-tolerant varieties. In the present study, forty-nine Tef genotypes were evaluated under strong acid soil (pH 4.97) and lime treated (pH 5.90) soils in the lathouse at Assosa Agricultural Research Center in 2017 to estimate the genetic variability, heritability and genetic advance of various traits of tef genotypes in relation to soil acidity stress. The result indicated that there was high significant (p<0.01) differences among genotypes for all traits under both environments; except for shoot biomass in the combined data analysis. The two environments differed significantly in their effect on all traits except on plant height, panicle length, culm length, total and fertile tillers and number of primary branches, although environment contribution to total TSS was less than 10% in 13 of the 17 traits studied; its high contribution was to harvest index (42.6%) and grain yield pot-1 (32.5%). Big reduction due to soil acidity was recorded for yield of primary panicle (27.78%), grain yield pot-1 (33.85%) and harvest index (35.6%). A contribution of G was from 44.5% in harvest index to 90.5% in panicle length. The GxE interaction was also significant for all traits and it contributed more than 15% in 11 of the traits, indicating inconsistency of performance of genotypes under acidic and lime treated soils. PCV, GCV, and GAM were high (>20%) for fertile tillers per plant, panicle weight, yield of primary panicle, grain yield, and harvest index under both acidity levels and in the combined analysis. Heritability was high (>60%) for all traits except for shoot biomass in the combined analysis and lime treated soil. In general, there was wide genetic variability in the traits studied pointing to the possibility of improving the desired traits, including grain yield under both environments and over environments through the selection of elite genotypes.

Website and blog are popular as a media to spread news. The validity of an article of news’s can either be valid or fake. A fake article of news is usually called a hoax news article. The purpose of making hoax news is to persuade, manipulate, affect to people to do something that contradicts or prevents the right action. A hoax news usually used threats or misleading information to make them believe things that are not real. This research proposes an experiment using naïve Bayes to detect hoax news in Bahasa Indonesia. In this research, we use our own dataset consisting of a total of 600 valid and hoax articles. We asked three reviewers to conduct manual classification for our dataset. Final tagging was obtained by adopting the maximum score from the three reviewers. In our experiment, we show that naïve Bayes can classify Indonesian online news articles with term frequency feature using the PHP-ML library component’s. We obtained an accuracy is 82.6% with static testing and 68.33% with dynamic testing. We give free access to the dataset so the future research can replicate, comparing the result and make a baseline testing.Keywords : Hoax News Detection, Naïve Bayes Classifier.

Published: September 2019

A ploidy chimera of the Meiwa kumquat (Fortunella crassifolia Swingle), which had been induced by treating the nucellar embryos with colchicine, and had diploid (2n = 2x = 18) and tetraploid (2n = 4x = 36) cells, was examined for its ploidy level, morphological characteristics, and sizes of its cells in its leaves, flowers, and fruits to reveal the ploidy level of each histogenic layer. Furthermore, the chimera was crossed with the diploid kumquat to evaluate the ploidy level of its reproductive organs. The morphological characteristics and the sizes of the cells in the leaves, flowers, and fruits of the chimera were similar to those of the tetraploid Meiwa kumquat and the ploidy periclinal chimera known as “Yubeni,” with diploids in the histogenic layer I (L1) and tetraploids in the histogenic layer II (L2) and III (L3). However, the epidermis derived from the L1 of the chimera showed the same result as the diploid Meiwa kumquat in all organs and cells. The sexual organs derived from the L2 of the chimera were significantly larger than those of the diploid. Moreover, the ploidy level of the seedlings obtained from the chimera was mostly tetraploid. In the midrib derived from the L3, the chimera displayed the fluorescence intensity of a tetraploid by flow cytometric analysis and had the same size of the cells as the tetraploid and the Yubeni. According to these results, the chimera is thought to be a ploidy periclinal chimera with diploid cells in the outermost layer (L1) and tetraploid cells in the inner layers (L2 and L3) of the shoot apical meristem. The chimera had desirable fruit traits for a kumquat such as a thick pericarp, a high sugar content, and a small number of developed seeds. Furthermore, triploid progenies were obtained from reciprocal crosses between the chimera and diploid kumquat.

Internet-of-Things (IoT) is an enabling technology for numerous initiatives worldwide such as manufacturing, smart cities, precision agriculture, and eHealth. The massive field data aggregation of distributed administered IoT devices allows new insights and actionable information for dynamic intelligent decision-making. In such distributed environments, data integrity, referring to reliability and consistency, is deemed insufficient and requires immediate facilitation. In this article, we introduce a distributed ledger (DLT)-based system for ensuring IoT data integrity which securely processes the aggregated field data. Its uniqueness lies in the embedded use of IOTA’s ledger, called “The Tangle”, used to transmit and store the data. Our approach shifts from a cloud-centric IoT system, where the Super nodes simply aggregate and push data to the cloud, to a node-centric system, where each Super node owns the data pushed in a distributed and decentralized database (i.e., the Tangle). The backend serves as a consumer of data and a provider of additional resources, such as administration panel, analytics, data marketplace, etc. The proposed implementation is highly modularand constitutes a significant contribution to the Open Source communities, regarding blockchain and IoT.

The G-protein-coupled estrogen receptor (GPER) mediates rapid non-genomic effects of estrogen. Although GPER is able to induce proliferation, it is down-regulated in breast, ovarian and colorectal cancer. During cancer progression, high expression levels of GPER are favorable for patients’ survival. The GPER-specific agonist G1 leads to an inhibition of cell proliferation and an elevated level of intracellular calcium (Ca2+). The purpose of this study is to elucidate the mechanism of G1-induced cell death by focusing on the connection between G1-induced Ca2+ depletion and endoplasmic reticulum (ER) stress in the estrogen receptor positive breast cancer cell line MCF-7. We found that G1-induced ER Ca2+ efflux led to the activation of the unfolded protein response (UPR), indicated by the phosphorylation of IRE1α and PERK and the cleavage of ATF6. The pro-survival UPR signaling was activated via up-regulation of the ER chaperon protein GRP78 and translational attenuation indicated by eIF2-α phosphorylation. However, the accompanying pro-death UPR signaling is profoundly activated and responsible for ER stress-induced cell death. Mechanistically, PERK-phosphorylation-induced JNK-phosphorylation and IRE1α-phosphorylation, which further triggered CAMKII-phosphorylation, are both implicated in G1-induced cell death. Our study indicates that loss of ER Ca2+ is responsible for G1-induced cell death via the pro-death UPR signaling.

Toxicity and the development of resistance by cancer cells are impediments for docetaxel (DTX), a primary drug for treating prostate cancer (PCa). Since the combination of DTX with natural compounds can increase its effectiveness by reducing its toxic concentrations, we evaluated a combination of thymoquinone (TQ) with DTX and determined its cytotoxicity against PCa cells (DU145 and C4-2B). This combination, in a concentration-dependent manner, resulted in synergistic cytotoxicity and apoptosis in comparison to either DTX or TQ alone. In addition, inhibition of cell survival pathways by PI3K/AKT inhibitors conferred sensitivity of DU145 and C4-2B cells to the combination as compared to the individual drugs. Moreover, the combined drugs (DTX+TQ) with inhibitors of PI3K/AKT increased the expression of pro-apoptotic markers (BAX and BID) along with caspase-3, PARP and decreased expression of the anti-apoptotic marker, BCL-XL. These data show that, for PCa cells, the cytotoxic effect of the DTX and TQ combination correlates with a block of the PI3K/AKT signaling pathway. These findings indicate that the combination of DTX and TQ, by blocking of the PI3K/AKT pathway, will improve the survival rate and quality of life of PCa patients.
Perceived Hunger in College Students Related to Academic and Athletic Performance

Published: September 2019

The current study examines perceived hunger, which may result from food insecurity, and its effect on academic and athletic performance in students on a liberal arts college campus in New Hampshire. It also examines how students compensate for hunger and their preferences for different types of resources to address hunger. A review of the literature on food insecurity in college students informed the development of a questionnaire on hunger. A mixed-method approach was used to collect qualitative/quantitative data from students of different disciplines. Three hundred and seventy-one students had complete surveys. Thirty-six percent and 34% of students reported that their academic and/or athletic performance, respectively, had been affected by hunger. Forty-seven percent of students responded they would consider taking advantage of an on-campus food pantry. In an open-ended question, students reported concerns about the social stigma related to economic instability and utilizing a food pantry. Our research findings support many on-campus initiatives including the creation of a student-run on-campus food pantry, longer dining common hours, a Swipe It Forward program, and the creation of a task force to address food insecurity on campus and to work with college systems to develop opportunities to better serve students at the college.
DAG-Based Distributed Ledger for Low-Latency Smart Grid Network
Authors: Park Seongjoon , Kim Hwangnam
Published: September 2019

In this paper, we propose a scheme that implements a Distributed Ledger Technology (DLT) based on Directed Acyclic Graph (DAG) to generate, validate, and confirm the electricity transaction in Smart Grid. The convergence of the Smart Grid and distributed ledger concept has recently been introduced. Since Smart Grids require a distributed network architecture for power distribution and trading, the Distributed Ledger-based Smart Grid design is a spotlighted research domain. However, only the Blockchain-based methods, which are a type of the distributed ledger scheme, are currently either being considered or adopted in the Smart Grid. Due to computation-intensive consensus schemes such as Proof-of-Work and discrete block generation, Blockchain-based distributed ledger systems suffer from efficiency and latency issues. We propose a DAG-based distributed ledger for Smart Grids, called PowerGraph, to resolve this problem. Since a DAG-based distributed ledger does not need to generate blocks for confirmation, each transaction of the PowerGraph undergoes the validation and confirmation process individually. In addition, transactions in PowerGraph are used to keep track of the energy trade and include various types of transactions so that they can fully encompass the events in the Smart Grid network. Finally, to ensure that PowerGraph maintains a high performance, we modeled the PowerGraph performance and proposed a novel consensus algorithm that would result in the rapid confirmation of transactions. We use numerical evaluations to show that PowerGraph can accelerate the transaction processing speed by over 5 times compared to existing DAG-based DLT system.

Published: September 2019

Effects of salt on anaerobic digestion are dosage-dependent. As salt is a widely used condiment in food processing, effects of salt are bound to be considered when food waste is digested. In this study, salt addition effects (0, 2, 4, 6, 9, 12 g∙L−1) on biogas and methane yields and kinetics of biogas production were researched. Meanwhile, component characteristics (food waste featured in carbohydrate, protein and fat, respectively) and fermentation concentrations (5 and 8 gVS∙L−1) were also taken into consideration. Results showed that 2–4 g∙L−1 salt addition was the optimal addition dosage for AD systems as they not only have the maximum biogas and methane yields, but also the maximum vs. removal in most cases. Also, according to the results of a modified Gompertz model, which is used to predict biogas and methane production rates, suitable salt addition can accelerate biogas production, improving the maximum biogas production rate (Rmax). Factorial design (2 × 2) proved that interaction of salt and fermentation concentrations was significant for food waste featured with carbohydrate and with protein (p < 0.05). High salt addition and fermentation concentration can break the AD system when the feeding material was food waste featured with carbohydrate, but for food waste featured with protein, interaction of fermentation concentrations and salt addition can alleviate inhibition degrees.

We studied the feasibility of image-based quantitative analysis of foxing stains on collections of old (16th–20th century) European books stored in the Rare Book Library of the Seoul National University in Korea. We were able to quantitatively determine the foxing affected areas on books from their photographs using a newly developed image processing software (PicMan) including cultural property characterization applications, specifically. Dimensional and color analysis of photographs were successfully done quantitatively. Histograms of RGB (red, green, blue) pixels of photographs clearly showed the change in color distribution of foxing stains compared to the other areas of the photographs. Several sample images of quantitative measurement of foxing stains and virtually restored images were generated to provide easy visual inspection and comparison between restored images and the original photographs. Image quality, resolution, and digital file format requirements for quantitative analysis are described. Image-based quantitative analysis of foxing stains on paper documents are found to be very promising towards automation for objective characterization of photographs of cultural properties. This technique can be used to create a cultural property digital database. Quantitative and statistical analysis techniques can be introduced to monitor the effect of storage and conservation environment on the cultural properties.

Bicycle tourism is one of the popular physical activities for sport tourists. Since the physical environment may affect bicycling behavior, it becomes an important determinant for cyclists to choose a cycleway. Exploratory factor analysis is performed to extract the perception of environmental quality of cyclists into five main factors, including safety, light facilities, lane design, landscape, and environment cleanliness. The contingent behavior method (CBM) is adopted to measure the quality improvement projects in different scenarios of light facility and landscape improvement. The results showed that the improvement projects increased the intended number of trips and the recreational benefits of cyclists.
