Authors: Husain Rahim , Suparmo Suparmo , Harmayani Eni , Hidayat Chusnul
Published: September 2017

Fish protein is oxidased easily during storage. The oxidation reaction rate can be approached through the order to zero or first order. The objective of this research was to study the oxidation rate during storage by determining the amount of activation energy (Ea) and constant change (k). The results showed that the increased of temperature storage from 0 °C to 40oC can increased the k value from 0.0617 to 0.311. The carbonyl content of red snapper protein isolate can be increased to higher level as storage temperature increase to 40 °C with higher level increase at higher temperature. The activation energy of oxidation reactions that cause oxidation of the protein is 42.015 Kj/mol.K to zero order. Kinetics increase in protein carbonyls: the higher the temperature storage protein isolate red snapper (Lutjanus sp), the greater the value of a constant (k) is obtained. Kinetics studies show that an increase in the rate of reaction of oxidative damage fish protein  (Lutjanus sp) during storage by following zero order reactions. ABSTRAKProtein ikan mudah rusak akibat oksidasi selama penyimpanan.

Do Firms Strategically Disseminate? Evidence from Corporate Use of Social Media
Authors: Jung Michael J. , Naughton James P. , Tahoun Ahmed , Wang Clare
Published: September 2017

We examine whether firms use social media to strategically disseminate financial information. Analyzing S&P 1500 firms' use of Twitter to disseminate quarterly earnings announcements, we find that firms are less likely to disseminate when the news is bad and when the magnitude of the bad news is worse, consistent with strategic behavior. Furthermore, firms tend to send fewer earnings announcement tweets and “rehash” tweets when the news is bad. Cross-sectional analyses suggest that incentives for strategic dissemination are higher for firms with a lower level of investor sophistication and firms with a larger social media audience. We also find that strategic dissemination behavior is detectable in high litigation risk firms, but not low litigation risk firms. Finally, we find that the tweeting of bad news and the subsequent retweeting of that news by a firm's followers are associated with more negative news articles written about the firm by the traditional media, highlighting a potential downside to Twitter dissemination.

Authors: Khoirunnisa Hanah , Wisha Ulung Jantama , Lubis Muhammad Zainuddin
Published: September 2017

This study tried to observe the correlation and coherency between sea surface temperature (SST) and wind velocity in the Malacca Strait at the year of 2015. The SST and wind velocity data with 6 hours interval step have been used in this study. S-Transform, the Cross Wavelet Transform, and the Wavelet Coherency were applied to observe the influence of the variation of sea surface temperature to the wind velocity in Malacca Strait. These methods could produce the phase lag and the time of occurrence between them. S-Transform was used to show the spectrum energy of the sea surface temperature variation. The strongest correlation between them has the period of 32 days during July to August and October to November at each point with significance level of 95 %. The coherency of them has the range of 4 to 64 days at each point. The last result is the spectrum energy of SST variation that has the period of 5 to 50 days at each point. It was similar to the result of the correlation and coherence period between the wind velocity and the SST data

Authors: Siswoyo Damper Dwijo , Utami Endang Sri
Published: September 2017

Mekanisme perdagangan di Bursa Efek Indonesia menjadi salah satu instrumen bagi pelaku pasar modal untuk masuk ke dunia investasi di Indonesia. Dalam perkembangannya BEI Self Regulatory Organization (SRO) berusaha untuk membuat kebijakan yang terbaik bagi pasar modal di Indonesia. Pada tanggal 6 januari 2014 sistem perdagangan tentang satuan perdagangan dan fraksi harga saham dirubah oleh BEI. Menurut studi peristiwa, suatu pengumuman atau informasi di pasar modal diukur untuk membuktikan apakah informasi yang masuk ke pasar menimbulkan reaksi pasar. Oleh karena itu penelitian ini bertujuan untuk memperoleh bukti empiris mengenai reaksi pasar terhadap suatu pengumuman yang diukur dengan abnormal return dan trading volume activity. Penelitian ini termasuk studi peristiwa, menggunakan metode market adjusted method dalam mencari abnormal  returnnya. Periode jendela yang digunakan adalah 8 hari sebelum peristiwa, 1 hari saat peristiwa dan  8 hari sesudah peristiwa. Jumlah sampel sebanyak 59 emiten dari sepuluh sektor industri berdasarkan JASICA, yang terdaftar di BEI Tahun 2014. Data yang digunakan sekunder dari data pasar Bursa Efek Indonesia yang kemudian diolah dengan one sampel kolmogorov-smirnov dan paired sampel t-test untuk mengetahui ada tidaknya perbedaan average abnormal return (AAR), rerata trading volume activity(TVA) sebelum dan sesudah peristiwa. Hasil dari penelitian ini membuktikan bahwa sepanjang periode pengamatan tidak terdapat perbedaan antara AAR sebelum dan AAR sesudah peristiwa. Dan terdapat perbedaan rerata TVA sebelum dan rerata TVA sesudah peristiwa  pada lima sektor industri yaitu sektor pertanian, sektor aneka industri, sektor industri barang konsumsi, sektor properti dan real estate, dan sektor insfratruktur, utilitas dan transportasi. Kelima sektor ini menunjukan aktivitas volume perdagangan yang meningkat sesudah terjadinya peristiwa. Secara garis besar penelitian ini membuktikan bahwa pengumuman tidak sepenuhnya mempunyai kandungan informasi yang material untuk membuat pasar bereaksi sehingga menambah keuntungan bagi investor dan meningkatkan likuiditas saham.

In-Use Emissions from 2010-Technology Heavy-Duty Trucks: Impact on Air Quality Planning in California
Authors: Yoon Seungju , Collins John F. , Misra Chandan , Herner Jorn D. , Carter Michael W. , Sax Todd P.
Published: September 2017

Introduction of a selective catalytic reduction system for heavy-duty diesel trucks (HDDTs) has substantially reduced emissions of oxides of nitrogen (NOx). However, it was found that in-use NOx emissions measured from three 2010-technology HDDTs were higher than the certification standard and higher than the levels measured during engine certification. In-use NOx emissions from three HDDTs tested over chassis dynamometer cycles were 1.7 to 9 times higher than the NOx certification standard of 0.20 grams per brake horsepower-hour, and the emissions measured with a portable emissions measurement system over highway test routes were up to five times higher than the certification standard. Such high in-use NOx emissions occurred primarily during low-speed operations (25 mph or less). This is a concern in California because more than 50% of running-exhaust NOx emissions from HDDTs will occur during low-speed operations that constitute only 11% of total vehicle miles traveled by 2025. This substantial contribution of NOx emissions during low-speed operations should be addressed carefully in the process of developing regulations and strategies to improve air quality in California. For better understanding and control of high in-use NOx emissions, there is a strong need for investigation of NOx control technologies effective at low-speed operation, differences between engine testing and whole vehicle testing procedures, and the roles of both engine certification requirements and in-use compliance requirements in reducing real-world NOx emissions.
Real-World Freeway and Ramp Activity and Emissions for Light-Duty Gasoline Vehicles
Authors: Frey H. Christopher , Delavarrafiee Maryam , Singh Sanjam
Published: September 2017

There are few data on differences in real-world emissions by in-use vehicles when they operate on freeway ramps compared with operations on the freeway itself. The objective of this paper is to quantify the variability in link-based emissions rates for on-ramps and off-ramps in comparison to rates on freeways. Real-world measurements were made with the use of a portable emissions measurement system (PEMS) for selected vehicles, ramps, and freeway segments. The methodology included development of a study design for field data collection of vehicle activity and emissions, execution of the study design, quality assurance of the raw data, and analysis of the quality-assured data. Four light-duty gasoline vehicles were driven on two routes, each composed of on-ramp, freeway, and off-ramp links. Data were collected for morning peak, evening peak, and off-peak time periods. A PEMS test was used to measure exhaust emissions of oxides of nitrogen (NOx), hydrocarbon (HC), and carbon monoxide (CO). The emissions rates for on-ramps were shown to be substantially higher than rates on freeways for NOx, HC, and CO. Some of this variability in emissions rates can be explained by link average vehicle specific power, which can vary by time of day and from one location to another. The variability in emissions rates by route and time of day indicates that there can be complex interactions between traffic flow, road geometry, and emissions rates. Recommendations are offered for additional study and regarding how these results can be used by researchers and practitioners.

Introduction: Abnormalities of serum testosterone level in males are observed in chronic kidney disease (CKD) patients. Erectile dysfunction, decreased libido, infertility in chronic kidney disease (CKD) patients is associated with low serum testosterone. So this study of CKD patients help early recognition of these adverse conditions associated with low serum testosterone level and thus specific actions may be taken earlier.Objective: To evaluate the serum testosterone level and the response of ADAM questionnaire in males with different stages of chronic kidney disease (CKD).Method: This cross sectional study was done From January to December, 2014 in the Department of Nephrology, Dhaka Medical College Hospital. A total of 90 diagnosed cases of adult male with different stages of CKD (CKD stage 3, 4, 5 and 5D) patients along with age matched 88 healthy individuals were included. Every subject was provided the Bangla version of ADAM questionnaire. Serum Testosterone was done by 125I-testosterone RIA system. P values <0.05 was considered as statistically significant.Result: Mean S. testosterone was found 4.29±1.9 ng/ml in CKD patients (group A) and 9.15±1.2 ng/ml in healthy subjects (group B). The mean S. Testosterone difference was statistically significant (p<0.05) between two groups. It was observed that positive response to ADAM questionnaire was found 11.4% in healthy subjects, 10.1% in CKD stage 3, 54.5% in CKD stage 4, 100% in CKD stage 5 and 5D. Among those groups only CKD stage 5 and 5D patients observed low S. testosterone and was found 39.1% and 84.0% respectively.Conclusion: Serum testosterone significantly decreased with progression of CKD stages. Positive ADAM questionnaire also found to be significant in CKD patients.J Dhaka Medical College, Vol. 26, No.1, April, 2017, Page 73-78
Immature Ovarian Teratoma with Gliomatosis Peritonei- an unusual finding
Authors: Nur Jinnatun , Akter Sumaya , Khanom Rashida
Published: September 2017

Immature ovarian teratoma is a rarely seen germ cell tumor and Gliomatosis peritonei (GP) is a rare condition that occurs almost exclusively in the setting of ovarian immature teratoma. It is characterisized by the occurrence of nodules of mature glial tissues in the peritoneum, omentum and bowel wall. The glial tissue in such cases is usually low grade although there have been cases of malignant evolution described. In general, the prognosis for GP is good. It depends chiefly on the degree of maturity of the implants. In mature GP, usually no additional chemotherapy is necessary. In immature GP, chemotherapy can induce maturation of the implants. We present a case of immature ovarian teratoma associated with low grade GP.J Dhaka Medical College, Vol. 26, No.1, April, 2017, Page 79-82

An Eco-Egalitarian Solution to the Capitalist Consumer Paradox: Integrating Short Food Chains and Public Market Systems
Authors: Pensado-Leglise Mario , Smolski Andrew
Published: September 2017

Presently, alternative agri-food networks are in a renaissance, utilizing an economy of proximity to compete against transnational agri-business and food distributors. While this is positive ecologically and socioeconomically, the overreliance on market mechanisms in short food chains has led to class distinctions in food distribution and consumption. The result has been a capitalist consumer paradox exacerbating inequality in the alternative agri-food networks. To resolve this inequality, we focused on how public policy can leverage state investment in public markets to reduce or overcome the capitalist consumer paradox in short food chains. To clarify our argument, we began by examining the benefits of short food chains in the urban food system. Then, we explained how type of consumption and policy regime effect food access. After this, we utilized Mexico City and New York City’s public market systems as representative of an alternative policy regime and the effects of moving away from state-oriented development. We concluded by describing possible conflicts and complements to the integration of public markets into short urban food chains.
The Catalytic Hydrogenation of Maleic Anhydride on CeO2−δ-Supported Transition Metal Catalysts
Authors: Liao Xin , Zhang Yin , Guo Junqiu , Zhao Lili , Hill Martyn , Jiang Zheng , Zhao Yongxiang
Published: September 2017

The proper selection of transition metals and support is pivotal to the design of active and selective catalysts for maleic anhydride hydrogenation (MAH). Herein, the M/CeO2−δ (M = Co, Ni, Cu, respectively) catalysts with pre-optimised metal loading of 10 wt % were prepared via a wet impregnation method and well characterized to corroborate their MAH performance with the properties of metal, support and the M/CeO2−δ catalysts. The results revealed that the metal dispersion on the catalyst declines in the order of Ni/CeO2−δ > Co/CeO2−δ > Cu/CeO2−δ, similar to the apparent activity for maleic anhydride (MA) transformation to succinic anhydride (SA). The hydrogenolysis of SA to γ-butyrolactone (GBL) occurs on Ni/CeO2−δ and Co/CeO2−δ only when the MA → SA transformation completing. The Ni/CeO2−δ displays superior activity and selectivity to Co/CeO2−δ in both MA → SA and SA → GBL reactions, while the Cu/CeO2−δ and CeO2−δ are both inert for SA → GBL hydrogenolysis. The MA hydrogenation to SA follows the first order kinetic law on the Ni/CeO2−δ and Co/CeO2−δ catalysts yet a more complex kinetic characteristics observed on the Cu/CeO2−δ. The distinct catalytic hydrogenation behaviours of the M/CeO2−δ catalysts are assigned to the synergism of dispersion and electronic configuration of the transition metals and oxygen vacancies.

Authors: Simonson Shawn
Published: September 2017

The flipped classroom has been receiving a lot of press lately as a more desirable way to manage the classroom and help students learn. However, flipping the classroom may not be appropriate for every course or every instructor. There may be a time when other active learning strategies are more appropriate to meet learning outcomes, student needs, and instructor capacity. This manuscript will discuss what flipping is and the decisions that an instructor might consider before flipping their classroom which might also enhance their implementation of this and other teaching strategies. A decision matrix is provided to illustrate this process.
Optimization and Practice of Support Working Resistance in Fully-Mechanized Top Coal Caving in Shallow Thick Seam
Authors: Huang Peng , Ju Feng , Jessu Kashi , Xiao Meng , Guo Shuai
Published: September 2017

Based on the overburdened structure of shallow coal seams in the West of China, the traditional support resistance method may not apply in such regions due to many roof shear and support crushing accidents. Four support working resistance indexes—rated working resistance, average working resistance, average-partial working resistance, and average-upper working resistance are counted as the candidate working resistance. The method of optimizing and inverting working resistance was put forward based on the roof control effect and working resistance overrun percentage. The simulation of a fully-mechanized top coal caving working face was built by using the UDEC software to analyze the top coal cavability and roof subsidence under different supporting strengths to determine the final working resistance. The project practice of 1322 working face in Jindi coal mine shows that the working resistance is 80–90% of calculated rated working resistance. The hydraulic support is worked under good condition. There is no pillar shrinkage and support crushing during coal mining.
An Improved Fuzzy C-Means Algorithm for the Implementation of Demand Side Management Measures

Published: September 2017

Load profiling refers to a procedure that leads to the formulation of daily load curves and consumer classes regarding the similarity of the curve shapes. This procedure incorporates a set of unsupervised machine learning algorithms. While many crisp clustering algorithms have been proposed for grouping load curves into clusters, only one soft clustering algorithm is utilized for the aforementioned purpose, namely the Fuzzy C-Means (FCM) algorithm. Since the benefits of soft clustering are demonstrated in a variety of applications, the potential of introducing a novel modification of the FCM in the electricity consumer clustering process is examined. Additionally, this paper proposes a novel Demand Side Management (DSM) strategy for load management of consumers that are eligible for the implementation of Real-Time Pricing (RTP) schemes. The DSM strategy is formulated as a constrained optimization problem that can be easily solved and therefore, making it a useful tool for retailers’ decision-making framework in competitive electricity markets.

The objective of this research was to study the relation between species richness and topography in the middle sub-tropical area of Eastern China. A species richness survey was conducted along altitude in Kaihua County, Zhejiang Province, Eastern China. Topographic variables, such as altitude, slope, aspect, terrain roughness, relief degree and the topographical wetness index, were extracted from the digital elevation model. The Generalized Additive Model (GAM), the linear model and the quadratic model were used to fit response curves of species richness to topographic variables. The results indicated that altitude and the topographical wetness index have a significant relation to species richness. Species richness has a unimodal response to altitude and a linear response to the topographical wetness index. However, no significant correlations were observed between slope, aspect and species richness. The predicted species richness by GAM is significantly correlated with the observed species richness, whereas the prediction error tends to increase with the increment of species richness. This study furthered insights into the relationship between topography and plants’ diversity in the middle sub-tropical area of Eastern China.

Yeast β-glucan polysaccharide is a proven immunostimulant molecule for human and animal health. In recent years, interest in β-glucan industrial production has been increasing. The yeast cell wall is modified during the fermentation process for biomass production. The impact of environmental conditions on cell wall remodelling has not been extensively investigated. The aim of this research work was to study the impact of glucose and NaCl stress on β-glucan formation in the yeast cell wall during alcoholic fermentation and the assessment of the optimum fermentation phase at which the highest β-glucan yield is obtained. VIN 13 Saccharomyces cerevisiae (S. cerevisiae) strain was pre-cultured for 24 h with 0% and 6% NaCl and inoculated in a medium consisting of 200, 300, or 400 g/L glucose. During fermentation, 50 mL of fermented medium were taken periodically for the determination of Optical Density (OD), cell count, cell viability, cell dry weight, β-glucan concentration and β-glucan yield. Next, dry yeast cell biomass was treated with lytic enzyme and sonication. At the early stationary phase, the highest β-glucan concentration and yield was observed for non-NaCl pre-cultured cells grown in a medium containing 200 g/L glucose; these cells, when treated with enzyme and sonication, appeared to be the most resistant. Stationary is the optimum phase for cell harvesting for β-glucan isolation. NaCl and glucose stress impact negatively on β-glucan formation during alcoholic fermentation. The results of this work could comprise a model study for yeast β-glucan production on an industrial scale and offer new perspectives on yeast physiology for the development of antifungal drugs.

Manganese (Mn) is an essential nutrient, but overexposure can lead to neurotoxicity. Given the essentiality of Mn in the diet, particularly during children’s growth and development, it is imperative to quantify dietary Mn intake in populations that may be exposed to industrial sources of Mn. Dietary absorption of Mn is inversely associated with iron (Fe) stores, yet there is currently no food frequency questionnaire (FFQ) to assess dietary Mn and Fe intake. The study objective was to develop and evaluate the validity of a FFQ to measure dietary Mn and Fe intake in pediatrics by comparing the estimated intakes of Mn and Fe with biomarkers: Mn in blood and hair and Fe in serum. This study utilized a subset of the Communities Actively Researching Exposure Study (CARES) population residing in Guernsey County, Ohio. Dietary Mn was not correlated with either blood or hair Mn; however, dietary Mn and serum ferritin were significantly correlated, with a correlation coefficient of 0.51, p < 0.01. Moreover, dietary Fe and serum ferritin were also significantly correlated, with a correlation coefficient of 0.51, p < 0.01. This FFQ is a valid measurement tool for Fe intake as measured by serum ferritin; however, Mn intake did not correlate with either blood or hair Mn.
Insights into the Diagnostic Potential of Extracellular Vesicles and Their miRNA Signature from Liquid Biopsy as Early Biomarkers of Diabetic Micro/Macrovascular Complications

Published: September 2017

Extracellular vesicles (EVs) represent a heterogeneous population of small vesicles, consisting of a phospholipidic bilayer surrounding a soluble interior cargo. Almost all cell types release EVs, thus they are naturally present in all body fluids. Among the several potential applications, EVs could be used as drug delivery vehicles in disease treatment, in immune therapy because of their immunomodulatory properties and in regenerative medicine. In addition to general markers, EVs are characterized by the presence of specific biomarkers (proteins and miRNAs) that allow the identification of their cell or tissue origin. For these features, they represent a potential powerful diagnostic tool to monitor state and progression of specific diseases. A large body of studies supports the idea that endothelial derived (EMPs) together with platelet-derived microparticles (PMPs) are deeply involved in the pathogenesis of diseases characterized by micro- and macrovascular damages, including diabetes. Existing literature suggests that the detection of circulating EMPs and PMPs and their specific miRNA profile may represent a very useful non-invasive signature to achieve information on the onset of peculiar disease manifestations. In this review, we discuss the possible utility of EVs in the early diagnosis of diabetes-associated microvascular complications, specifically related to kidney.
Soy Expansion and Socioeconomic Development in Municipalities of Brazil

Soy occupies the largest area of agricultural land in Brazil, spreading from southern states to the Amazon region. Soy is also the most important agricultural commodity among Brazilian exports affecting food security and land use nationally and internationally. Here we pose the question of whether soy expansion affects only economic growth or whether it also boosts socioeconomic development, fostering education and health improvements in Brazilian municipalities where it is planted. To achieve this objective, we divided more than 5000 municipalities into two groups: those with >300 ha of soy (soy municipalities) and those with <300 ha of soy (non-soy municipalities). We compared the Human Development Index (HDI) and the Gini coefficient for income for these two groups of municipalities in 1991, 2000, and 2010. We made such comparison at the municipality level for the whole country, but we also grouped the municipalities by major geographical regions and states. We found that the HDI was higher in soy municipalities, especially in the agricultural frontier. That effect was not so clear in more consolidated agricultural regions of the country. Soy municipalities also had a higher Gini coefficient for income than non-soy municipalities. We concluded that soy could be considered a precursor of socioeconomic development under certain conditions; however, it also tends to be associated with an increase in income inequality, especially in the agricultural frontier.

A recent theoretical work indicates that intermetallic materials LiMnZ (Z = N, P) with a half-Heusler structure exhibit half-metallic (HM) behaviors at their strained lattice constants, and the magnetic moments of these alloys are expected to reach as high as 5 μB per formula unit. (Damewood et al. Phys. Rev. B 2015, 91, 064409). This work inspired us to find new Heusler-based half-metals with the largest magnetic moment. With the help of the first-principles calculation, we reveal that XCrZ (X = K, Rb, Cs; Z = S, Se, Te) alloys show a robust, half-metallic nature with a large magnetic moment of 5 μB at their equilibrium and strained lattice constants in their most stable phases, while the excellent HM nature of LiCrZ (Z = S, Se, Te) alloys can be observed in one of their metastable phases. Moreover, the effects of uniform strain in LiCrZ (Z = S, Se, Te) alloys in type II arrangement have also been discussed.

Carnobacterium maltaromaticum is frequently associated with foods having extended shelf-life due to its inhibitory activity to other bacteria. The quantification of such inhibition interactions affected by various environmental factors is limited. This study investigated the effect of environmental factors relevant to vacuum-packaged beef on inhibition between two model isolates of C. maltaromaticum, D0h and D8c, specifically D8c sensitivity to D0h inhibition and D0h inhibitor production. The effects of temperature (−1, 7, 15, 25 °C), atmosphere (aerobic and anaerobic), pH (5.5, 6, 6.5), lactic acid (0, 25, 50 mM) and glucose (0, 0.56, 5.55 mM) on D8c sensitivity (diameter of an inhibition zone) were measured. The effects of pH, glucose, lactic acid and atmosphere on D0h inhibitor production were measured at 25 °C. Sensitivity of D8c was the highest at 15 °C, under aerobic atmosphere, at higher concentrations of undissociated lactic acid and glucose, and at pH 5.5 (p < 0.001). pH significantly affected D0h inhibitor production (p < 0.001), which was the highest at pH 6.5. The effect of lactic acid depended upon pH level; at relatively low pH (5.5), lactic acid decreased the production rate (arbitrary inhibition unit (AU)/mL/h). This study provides a quantitative description of intra-species interactions, studied in in vitro environments that are relevant to vacuum-packaged beef.
Prayer, Meditation, and Anxiety: Durkheim Revisited
Authors: Bartkowski John , Acevedo Gabriel , Van Loggerenberg Harriet
Published: September 2017

Durkheim argued that religion’s emphasis on the supernatural combined with its unique ability to foster strong collective bonds lent it power to confer distinctive social benefits. Subsequent research has confirmed these propositions with respect to religion and mental health. At the same time, meditation has been linked to mental health benefits in intervention-based studies. Our investigation offers a unique test of two comparable inhibitors of anxiety-related symptoms in the general population, namely, prayer versus meditation. Using data from the 2010 wave of the Baylor Religion Survey, we find that frequent communal prayer is correlated with an increased incidence of anxiety-related symptoms whereas worship service attendance is negatively associated with reported anxiety. Attendance also combines with communal prayer to yield anxiety-reducing benefits. Meditation, measured as a dichotomous indicator, is unrelated to reported anxiety in our sample of American adults. Our study underscores the selective efficacy of collective forms of religious expression, and points to several promising directions for future research.
