Authors: Khadka Chakra Bahadur
Published: August 2019

This paper examines the degree to which the commercial banks of Nepal used risk management practices and techniques in dealing with different types of risk. The structural equation modeling (SEM) is applied in this study to analyze profit maximization and risk minimization of commercial banks in Nepal. Symmetry and balance to cover four aspects and four components of risk management and use of quantitative data from Banking and Financial Statistics of NRB is considered in the study. SEM is the cross-sectional statistical modeling. Factor analysis, path analysis and regression equation SLs are used for data analysis. Maximum likelihood estimation is the additional estimation equation. The significant findings of the study are: important types of risk being faced by the commercial banks of Nepal like credit risk, operational risk, and interest rate risk. Study also finds that the Nepalese commercial banks staff members properly understand risk and its management. Most of the components of risk management are very sound. There is a strong, positive relationship between risk management practices and understanding of risk and its management, board and senior management oversight, risk assessment and measurement, ownership structure and presence of separate risk manager. Findings of the paper are limited to the RMPs of commercial banks of Nepal. Results help to understand the current practices of Commercial Banks of Nepal. Findings can be used as a valuable feedback on improvement to RMPs and will be of significance to those who are interested in the banking sector of Nepal.

Authors: Sugianto
Published: August 2019

Potensi pesisir pantai di Indramayu yang banyak ditumbuhi pohon mangrove itu, merupakan aset berharga yang bisa dimanfaatkan untuk meningkatkan kesejahteraan masyarakat. Namun sayangnya kondisi pantai banyak yang rusak akibat terjangan abrasi, hal itu disebabkan hampir 18 ribu hektare hutan pantai di Indramayu kondisinya kritis. Salah satu penyebab utama kerusakan hutan mangrove di Indramayu karena kurang kesadarannya masyarakat tentang manfaat olahan dari mangrove sehingga bernilai ekonomi. Masyarakat berpendapat bahwa menjadikan hutan bakau sebagai area pertambakan lebih menguntungkan dari segi ekonomi ketimbang memanfaatkan mangrove menjadi olahan makanan, minuman atau menjadi bahan baku kosmetik. Oleh karena itu secara umum tujuan dalam penelitian ini yakni (1) merubah paradigma masyarakat pesisir kabupaten Indramayu bahwa tumbuhan mangrove dapat diversifikasi menjadi olahan makanan, minuman dan obat-obat yang bernilai ekonomi tinggi; (2) meningkatkan kesejahteraan ekonomi masyarakat pesisir Indramayu. Metode  yang  digunakan  dalam  penelitian  adalah metode  survey,  yaitu metode  yang  dilakukan  untuk mengadakan  pemeriksaan  yang berlangsung  di  lapangan atau  lokasi penelitian.

CELLULOSE MONOACETATE/NAFION (CMA/N) HYBRID NANOFIBERS AS INTERFACE FOR ELECTROCHEMICAL DNA BIOSENSORS
Authors: BOSTANCI Ayşe , ALADAG TANIK Nilay , AYKUT Yakup
Published: August 2019

Nafion/cellulose
monoacetate (CMA/N) hybrid nanofibers were produced via a one-step
electrospinning method. Nanofibers morphologies transformed from uniform to
bead on a string defect morphology with increasing Nafion ratio in CMA/N hybrid
nanofibers. The melting point of CMA was detectable at DSC measurement, but the
addition of Nafion didn’t allow a proper crystallization of CMA and melting peak
disappeared after the Nafion addition. Decomposition temperature decreased
dramatically with the addition of Nafion into CMA/N nanofibers and
decomposition took place at a broad temperature range. Differential pulse
voltammetry (DPV) analyses were conducted to observe the guanine oxidation
signal at neat and NH-modified DNA on the as-prepared nanofiber sensory system.
Maximum oxidation signals were obtained from pure CMA nanofibers at neat ssDNA.
Comparing neat DNA, signal intensity increased with the addition of Nafion into
CMA/N nanofibers at NH-modified ssDNA sample. The examined CMA/N hybrid
nanofibers could be a promising DNA biosensor devices.

Authors: Tatsiana G. Shahava
Published: August 2019

The subspace of rational distributions was considered it this paper. Distribution is called rational if it has analytical representation f = (f+, f-) where functions f+ and f- are proper rational functions. The embedding of the rational distributions subspace into the rational mnemofunctions algebra on was built by the mean of mapping Ra(f)=fε(x)=f+(x+iε)-f-(x-iε). A complete description of this algebra was given. Its generators were singled out; the multiplication rule of distributions in this algebra was formulated explicitly. Known cases when product of distributions is a distribution were analyzed by the terms of rational mnemofunctions theory. The conditions under which the product of arbitrary rational distributions is associated with a distribution were formulated.

Introduction: The landscape of Crohn disease (CD) is ever-changing. Incidence continues to vary as different population adapt to the  modern wester diet which consists mainly from processed foods. Material and Method: Our study is retrospective, data was gathered from three University Hospitals in Bucharest, Romania. To be included in the study, patients had to have a positive diagnostic of CD. Results: The patient with CD which requires surgery in Romania is: male, comes from an urban enviroment is a smoker, under 50 years of age. In his case CD frequently affects the small intestine, is frequently operated in emergency settings, frequently operated for intestinal obstruction. The patient has an average duration from diagnosis to surgery of 1-3 years. The relapse free period is 2.3years. Conclusion: Despite its global trend regarding the distribution of surgical interventions to those performed under elective conditions, a tendency has been observed in Romania for surgical interventions done for life-threatening complications in emergency settings. The public / patients need to be better informed about CD and its complications to seek medical help before surgery becomes mandatory.

Objective: The aim of this study was to assess and
compare the dentin tubule penetration effectiveness of a dental adhesive  and a resin infiltration system used with two
different surface treatments.

Methods: Dentin specimens were obtained from 42
impacted lower right wisdom tooth, 2 of these specimens were used to detect the
effects of surface treatments. Two different surface treatments (37% phosphoric
acid and 17% EDTA) were applied to the samples to compare the dentin tubule
penetration effectiveness of a dental adhesive –which had been using for
treatment of dentin hypersensitivity- (Adper Single Bond 2, 3M, Germany) and a
resin infiltration system (ICON, DMG, Germany). Scanning electron microscopy
was used to investigate the tubule penetration effectiveness. For statistical
analysis, Kruskal Wallis and Mann Whitney U and 
One Way Analysis of Variance (ANOVA) and Tukey HSD tests were used.Results: ICON
had shown significantly more resin penetration intensity and more resin
penetration depth than Adper Single Bond 2 (p<0.05). Phosphoric acid
treatment groups had shown significantly more penetration intensity than EDTA
treated groups (p=0.001).

Conclusion: According to the results of this study, it
can be concluded that tubuler penetration effectivenes of ICON resin
infiltration system is better than Adper Single Bond 2 adhesive system.

Published: August 2019

Objective: The aim of this study was to evaluate expectation, attitude, and preconceptions regarding dental implant therapy among a selected sample group of dental patients who applied for implant treatment.Methods: This cross-sectional hospital-based study was carried out using a questionnaire with 132 patients who applied for implant treatment. The study questionnaire contained 20 multiple-choice questions on the patients’ demographics, sources of information, knowledge, attitude, expectations, and related factors regarding dental implant treatment.Results: Majority of the patients stated that they did not have enough knowledge about implant treatment procedure to be applied. Of the patients, 23.5% thought that the implant would be used for a lifetime, 56.8% thought that post-implant care should be like the natural teeth care, 36.4% stated that implants need more care than natural teeth. They stated that the major disadvantages of implant treatment were the high cost (53.0%), difficulty in treatment (28.0%), and long treatment time (18.9%). It was determined that the main reason for the delay was the high cost of the treatment. As education level rose, the preference for a removable denture decreased (p<0.05)Conclusion: According to the results we obtained from a limited sample, patients may have misinformation and incomplete expectation about implant therapy. Informing and educating the patients is very important for deciding which treatment to pursue and setting realistic patient expectations regarding treatment outcomes.

Objective: The purpose of our study is to investigate the immunomodulatory effects of Dental Follicle Mesenchymal Stem Cells (DF-MSCs) on lymphocytes isolated from peripheral blood of AD patients, a Th2 disease and psoriasis, a Th1 / Th17 disease and compare them with healthy individuals in vitro.Methods: Patients with the AD (n = 9) and psoriasis (n = 6) who are followed up in Marmara University Pediatric Allergy and Immunology and Dermatology outpatient clinics and healthy subjects (n = 6) were included. Peripheral Blood Mononuclear Cells (PBMCs) were isolated from 20 ml of venous blood of all participants. Cells were cultured for 72 hours in the absence and presence of DF-MSCs with anti-CD3/anti-CD28 stimulation or without stimulation. At the end of this period, CD4+ and CD8+ T lymphocyte proliferation and cytokine levels from the culture supernatants were analyzed by flow cytometry.Results: In the presence of DF-MSCs, proliferation ratio was suppressed in both CD4+ and CD8+ cells in AD and psoriasis patients (p<0,05). IFN-γ levels significantly increased in AD patients in the presence of DF-MSCs (p<0,05) whereas decreased significantly in psoriasis patients in the presence of DF-MSCs (p<0,05). IL-4 levels significantly decreased in AD patients in the presence of DF-MSCs (p<0,05) but remained unchanged in psoriasis patients (p>0,05). IL-10 increased significantly in both groups in the presence of DF-MSCs (p<0,05).Conclusion: Our results support immunoregulatory effects of DF-MSCs on both AD and psoriasis which are Th2 and Th1 / Th17 dominant diseases respectively. Our evidence-based results demonstrated that DF-MSCs could have a beneficial therapeutic implication for inflammatory skin diseases.
The Present and Future Role of Acoustic Metamaterials for Architectural and Urban Noise Mitigations
Authors: Kumar Sanjay , Lee Heow
Published: August 2019

Owing to a steep rise in urban population, there has been a continuous growth in construction of buildings, public or private transport like cars, motorbikes, trains, and planes at a global level. Hence, urban noise has become a major issue affecting the health and quality of human life. In the current environmental scenario, architectural acoustics has been directed towards controlling and manipulating sound waves at a desired level. Structural engineers and designers are moving towards green technologies, which may help improve the overall comfort level of residents. A variety of conventional sound absorbing materials are being used to reduce noise, but attenuation of low-frequency noise still remains a challenge. Recently, acoustic metamaterials that enable low-frequency sound manipulation, mitigation, and control have been widely used for architectural acoustics and traffic noise mitigation. This review article provides an overview of the role of acoustic metamaterials for architectural acoustics and road noise mitigation applications. The current challenges and prominent future directions in the field are also highlighted.

Terminal drought greatly enhanced Aspergillus flavus Link infection (AI) and aflatoxin contamination (AC) in peanut. Identification of new surrogate traits which have an association with AC may be effective to improve peanut varieties with reduced AI and AC. The objective of this work was to examine the relationships of nutrient uptake and N2-fixation (NF) with AC in peanut in a terminal drought condition. Five peanut varieties were tested in well-watered (WW) and terminal drought (TD) conditions (1/3 available water (AW) from R7 (7th reproductive growth stage; beginning of pod maturity stage)). Data were collected for nutrient uptake (nitrogen, phosphorus, potassium, calcium, magnesium), nodule dry weight (NDW), and NF. AI and AC were also examined. Nutrient uptake, NDW, and NF had negative and significant correlations with AI and AC in the TD condition. Negative and significant correlations of the drought tolerance index of nutrient uptake, NDW, and NF with AI and AC were also observed in the TD condition. The results showed that the ability to maintain nutrient uptake and NF in TD might be a mechanism of tolerance to AI and AC. Moreover, due to their negative impacts on AI and AC, nutrient uptake and NF could be used as selection traits for resistance to AI and AC in peanut in TD.
Economic Benefits of Controlling Red Rice: A Case Study of the United States
Authors: Durand-Morat Alvaro , Nalley Lawton Lanier
Published: August 2019

Red rice (O. sativa) is one the most prevalent and damaging weed problems in direct seeding rice systems worldwide and can cause significant losses in rice productivity and quality. Red rice has been a problem in the United States for decades, and it is a growing problem in Asia, where 90 percent of the global rice production occurs. Unlike for other crops, where genetically engineered (GE) herbicide tolerant varieties are available, to date, Clearfield (CL) and Provisia rice are the only technologies available to selectively control red rice using chemical herbicides in commercial rice fields. We develop a counterfactual scenario without CL rice and ascertain the yield and quality losses due to red rice infestation in the Mid-South of the United States. Our findings suggest that even with the higher costs of CL rice, relative to non-CL rice, that the returns are $0.15, $0.36, and $0.54 more for every dollar invested than non-CL rice with a light, moderate, and heavy initial red rice infestation rate, respectively. These results imply that the higher upfront costs for CL rice are offset by more than proportional higher profits relative to their non-CL rice counterparts.

According to the assumptions of Organisation for Economic Co-operation and Development OECD, the share of biofuels in the global transport sector is estimated to reach 15–23% by 2050. The triticale can be used to produce bioethanol. The appropriate production process should generate as much renewable energy as possible per production unit. Plant production can be carried out in various tillage systems and using appropriate doses of nitrogen fertilization. The objective of this study is to compare the effect of traditional tillage system (TRD) and reduced (RED) tillage technology and nitrogen fertilizer (0, 40, 80, 120 kg N ha−1) on grain and bioethanol yield of spring triticale. The field experiment was performed in the south east of Poland (50°42′ N, 23°15′ E) on medium dystrophic typical brown soil. Based on research and calculations, the TRD system and between 40 and 80 kg ha−1 of N fertilizer are recommended for use in the cultivation of triticale for bioethanol production purposes. Such a variant will ensure a sufficient yield of grain (5.190 and 5.803 t ha−1), starch (3.462 and 3.871 t ha−1) and bioethanol (2487.3 and 2780.7 L ha−1) and good agronomic efficiency of N fertilizer (16.96 and 12.15 L of bioethanol per 1 kg of nitrogen (N) applied). The best ratio of energy efficiency of bioethanol production (EROI—Energy Return on (Energy) Investment or “net energy”) was recorded for the TRD system (1.138:1) and for the N fertilizer at 40 kg N ha−1 (1.144:1).

Background: Research efforts have focused on the evaluation of the bioactive quality of animal products (milk, cheese, meat, and other by-products) contrasting various feeding strategies coming from different ecological zones. The study aimed to describe the fatty acids (FA), polyphenols (P), bioactive compounds (BC), and antioxidant activity (AA) of goat’s milk. Methods: Dairy goats were fed with five systems: (1) Grazing; (2) conventional diet (CD); (3) CD + 10% of Acacia farnesiana (AF) pods; (4) CD + 20% AF; and (5) CD + 30% AF. The fatty acid profile, health promoting and thrombogenic indexes were calculated. Milk extracts were evaluated by HPLC to determent phenolic compounds (gallic, caffeic, chlorogenic, and ferulic acids, catechin, epicatechin, and quercetin). Antioxidant activity of goat’s milk extract was evaluated using 2,2-diphenyl-1-picrylhydrazyl radical (DPPH•), oxygen radical absorbance capacity (ORAC), and the ferric reducing antioxidant power (FRAP) assays. Results: Conventional diet showed the highest content of polyunsaturated fatty acids while grazing showed the best n-6:n-3 and the linoleic:alpha linolenic acid ratio. Similarly, grazing and AF boosted the polyphenol content. Conclusions: Acacia farnesiana inclusion in the goats’ diets increased the presence of bioactive compounds and the antioxidant activity while diminishing the cholesterol content of goat’s milk.

In this study, common cereal grains were partially replaced by former foodstuffs products (FFPs) in post-weaning piglets’ diets, to investigate how these alternative ingredients influence the faecal microbiota in the post-weaning period. Twelve post-weaning piglets were housed for 16 days in individual pens and were then fed two diets: a standard wheat-barley-corn meal diet and a diet containing 30% FFPs, thus partially substituting conventional cereals. The growth performance was monitored and faecal microbiota was characterized by the next generation sequencing of the 16S rRNA gene. The results showed no detrimental effects on growth performance when FFPs were used. However, the FFP diet decreased the bacterial richness and evenness in the large intestine, while minor differences were observed in the taxa composition. The core microbiota composition was only slightly affected, and no differences between the two groups in the gut microbiota composition at the phylum level over time were observed. Thus, although these results should be interpreted with caution, as they are case-specific, FFPs can be potentially used as alternative carbohydrate sources in post-weaning piglets, but further investigations are necessary to clarify their impact on gut health when used for a longer period.

The Awassi breed is desirable due to its resilient traits, but shows poor lean meat content on the carcass; the callipyge mutation may enhance growth and meat characteristics. The first backcross of callipyge Awassi–Rambouillet (CRAW) lambs was generated by mating Awassi ewes with heterozygous F1 (50 % Awassi and 50 % Rambouillet) rams for the callipyge mutation. A fattening trial with carriers of CLPG (CRAW), non-carriers (RAW), and Awassi (AW) ram lambs was conducted for 94 days and growth and meat characteristic parameters were recorded. Final body weight, average daily gain (ADG), feed conversion ratio, and dry matter intake, but not initial body weight, were greater in CRAW and RAW lambs as compared to AW lambs; hot and cold carcass, dressing percentage, and shoulder, rack, and loin weights were greater in CRAW vs. AW but not RAW lambs. Leg cuts were heavier in CRAW vs. both RAW and AW lambs; intermuscular and subcutaneous fat percentages were greater in CRAW as compared to AW but not RAW lambs. Non-carcass components showed kidney fat, kidney, liver and testes weights higher in CRAW lambs as compared to AW lambs, but these parameters were similar to those of RAW lambs. There were no differences in fat tail weight. Further, CRAW lambs had higher shear force and water holding capacity than RAW and AW lambs, while cooking loss was the lowest in CRAW lambs. In conclusion, the callipyge mutation with 25% Rambouillet genes can provide efficient improvements in growth and meat characteristics, with the exception of tenderness in Awassi sheep.

Oxidative stress and inflammation in neuron-glia system are key factors in the pathogenesis of neurodegenerative diseases. As synthetic drugs may cause side effects, natural products have gained recognition for the prevention or management of diseases. In this study, hot water (HE-HWA) and ethanolic (HE-ETH) extracts of the basidiocarps of Hericium erinaceus mushroom were investigated for their neuroprotective and anti-inflammatory activities against hydrogen peroxide (H2O2)-induced neurotoxicity in HT22 mouse hippocampal neurons and lipopolysaccharide (LPS)-induced BV2 microglial activation respectively. HE-ETH showed potent neuroprotective activity by significantly (p < 0.0001) increasing the viability of H2O2-treated neurons. This was accompanied by significant reduction in reactive oxygen species (ROS) (p < 0.05) and improvement of the antioxidant enzyme catalase (CAT) (p < 0.05) and glutathione (GSH) content (p < 0.01). Besides, HE-ETH significantly improved mitochondrial membrane potential (MMP) (p < 0.05) and ATP production (p < 0.0001) while reducing mitochondrial toxicity (p < 0.001), Bcl-2-associated X (Bax) gene expression (p < 0.05) and nuclear apoptosis (p < 0.0001). However, gene expression of Nuclear factor erythroid 2-related factor 2 (Nrf2), heme oxygenase 1 (HO-1) and NAD(P)H quinone dehydrogenase 1 (NQO1) were unaffected (p > 0.05). HE-ETH also significantly (p < 0.0001) reduced nitric oxide (NO) level in LPS-treated BV2 indicating an anti-inflammatory activity in the microglia. These findings demonstrated HE-ETH maybe a potential neuroprotective and anti-inflammatory agent in neuron-glia environment.

In this study the effect of the ethanol concentration of Bougainvillea x buttiana extracts on the flavonoids content, and its antioxidant and cytoprotective activities in vitro were determined and compared. For the elucidation of the chemical constituents, the high-performance liquid chromatography method (HPLC) was used, and verification of the antioxidant activity was carried out using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical method. The cytoprotective effects of extracts were determined by exposure to hydrogen peroxide. The HPLC analysis showed the presence of rutin, quercetin-3-glucoside and quercetin rhamnoside. Among the extracts investigated the best recuperation of the rutin content was observed in extracts with 80% ethanol (83 ± 5 mg/mL). The amounts of rutin present in all extracts contribute to the antioxidant capacity and the IC50 was 427.49 (0%), 275.41 (50%), 271.61 (80%), and 272.14 (100%) µg/mL. The lowest percentage of viability was found in the cultures exposed to 100% ethanol (92%). In cultures exposed to hydrogen peroxide the percentages of protection were 25%, 33%, 78%, and 65% for cultures treated for 72 h at 0%, 50%, 80%, and 100% ethanol, respectively. The ethanolic extract of B. x buttiana was confirmed to have high rutin content with potent antioxidant activity, low cytotoxic and strong cytoprotective effects.

Production of versatile composites is a very attractive field. Carbon containing epoxy resins are one of the most relevant reinforced plastics used for a wide number of applications. In this research, we studied the influence of five different commercial biochar samples for the selective enhancement of brittleness and ductility of an epoxy based composite. We proved the relationship between biochar morphology and composites mechanical properties with the aid of FT-IR and FE-SEM analysis. We were able to improve the neat resin mechanical properties by doubling its Young’s modulus and ultimate tensile strength using a wheat straw derived material, and to increase its elongation by 40%, we used a Miscanthus derived biochar.
Failure Diagnosis of Demagnetization in Interior Permanent Magnet Synchronous Motors Using Vibration Characteristics
Authors: Ishikawa Takeo , Igarashi Naoto
Published: August 2019

The detection of a precursor to the demagnetization of permanent magnets is very important because a high degree of reliability is necessary in permanent magnet synchronous motors (PMSMs). This paper investigated the diagnosis of very slight PM demagnetization. A part of the permanent magnet was altered to non-magnetic material so as to mimic the effect of demagnetization. The vibration characteristics were clarified for low demagnetization in PMSMs driven under vector control by experiments and 3D finite element (FE) analysis. We found that the amplitude of some components of the vibration was approximately proportional to the demagnetization level of the PM and the load torque. Therefore, the measurement of vibration and torque is very useful for the estimation of the magnetization level of PMSMs under vector control except for under very light load.
