STATISTICAL ANALYSIS OF GROWTH CONDITIONS OF NEWLY ISOLATE BACILLUS SP. PRODUCING L-ASPARAGINASE

The concentrations of nutrient elements together with several physical parameters were screened to find out the significant factors for the production of Lasparaginase from newly isolated strain, Bacillus sp. from Sg Klah, Hot Spring, Perak. Then, the significant factors were optimized for enhancing L-asparaginase production from the bacterium strain. Two statistical designs, Two Level Factorial Design and Face Centered Composite Design (FCCD), Design expert @version 8.0 were employed in screening and optimization of the process variables, respectively. The results for all experiment runs were analyzed by analysis of variance (ANOVA). Peptone (nitrogen source) concentration and temperature were found as significant factors, positively influenced the production of Lasparaginase. The two factors were then optimized to increase the desired enzyme production. The optimum peptone concentration and the temperature were found at 1.4 g/L and 30oC, respectively. The L-asparaginase production under optimized conditions increased from 0.15±0.023 U/mL to 0.19 ± 0.03 U/mL. The kinetic studies showed that the biomass production dropped after 24 hours while L-asparaginase activity is active and positively increased until the fermentation period ended.

Estimation of ANN prediction bounds for the suspended sediment load modeling

In this paper, the point prediction of the Artificial Neural Network (ANN) for the suspended sediment load modeling was evaluated for the Lighvanchai River located in Iran, in monthly and daily scales. Since point prediction of ANN convey no information about the accuracy of prediction, so prediction intervals (PIs) were constructed by the Bootstrap method as a most frequently used technique for assessing the uncertainty of ANN. In this way, the accuracy of PIs was quantified by coverage and width criteria. The results showed that the ANN-based modeling in daily scale had better performance compared to that in monthly scale and Nash Sutcliff efficiency was 32% higher in daily scale compared to monthly. Moreover, the width and coverage of the constructed PIs in daily scale were 14% and 24%, lower and higher compared to that in monthly scale and the Bootstrap method could appropriately capture the target values.
Social Media Rumor Refuter Feature Analysis and Crowd Identification Based on XGBoost and NLP

One prominent dark side of online information behavior is the spreading of rumors. The feature analysis and crowd identification of social media rumor refuters based on machine learning methods can shed light on the rumor refutation process. This paper analyzed the association between user features and rumor refuting behavior in five main rumor categories: economics, society, disaster, politics, and military. Natural language processing (NLP) techniques are applied to quantify the user’s sentiment tendency and recent interests. Then, those results were combined with other personalized features to train an XGBoost classification model, and potential refuters can be identified. Information from 58,807 Sina Weibo users (including their 646,877 microblogs) for the five anti-rumor microblog categories was collected for model training and feature analysis. The results revealed that there were significant differences between rumor stiflers and refuters, as well as between refuters for different categories. Refuters tended to be more active on social media and a large proportion of them gathered in more developed regions. Tweeting history was a vital reference as well, and refuters showed higher interest in topics related with the rumor refuting message. Meanwhile, features such as gender, age, user labels and sentiment tendency also varied between refuters considering categories.
Evaluation of the Lipophilicity of New Anticancer 1,2,3-Triazole-Dipyridothiazine Hybrids Using RP TLC and Different Computational Methods

Two new anticancer-active 1,2,3-triazole-dipyridothiazine hybrids were evaluated for their lipophilicity using thin-layer chromatography (TLC) and computational methods. The experimental lipophilicity was evaluated with mobile phases (mixtures of TRIS buffer and acetone), exploiting a linear correlation between the retention parameter (RM) and the volume of acetone. The relative lipophilicity parameter (RM0) was obtained by extrapolation to 0% acetone concentration. This parameter was intercorrelated with a specific hydrophobic surface area (b) revealing two congeneric subgroups: hybrids of 1,2,3-triazole-2,7-diazaphenothiazines and 1,2,3-triazole-3,6-diazaphenothiazines. The parameter RM0 was converted into the absolute lipophilicity parameter logPTLC using a calibration curve prepared on the basis of compounds of known logP values. Triazole–dipyridothiazine hybrids turned out to be medium lipophilic with logPTLC values of 1.232–2.979. The chromatographically established parameter logPTLC was compared to the calculated lipophilic parameter logPcalcd obtained with various algorithms. The lipophilicity was correlated with molecular descriptors and ADME properties. The new triazole–dipyridothiazine hybrids followed Lipinski’s rule of five. The lipophilicity of these hybrids was dependent on the substituents attached to the triazole ring and the location of the azine nitrogen atoms.
How Do Mutual Funds in China Exploit Investor Sentiment?

ABSTRACT Mutual funds in China that invest heavily in stocks with high sentiment beta deliver poorer performance when standard risk factors and fund characteristics are controlled. However, these funds attract more new investment, which is somewhat puzzling. Funds adopting such a sentiment-catering strategy follow less idiosyncratic strategies and tend to increase risk taking. The impact of fund sentiment beta is more significant in bull markets than in bear markets, and more pronounced for growth and balanced funds than for value funds. Together, the findings suggest that Chinese mutual funds exploit investor sentiment for self-serving purposes.
Care to sleep? Daily caregiving and sleep problems in an ageing European population

ABSTRACT Informal caregiving is increasingly common in our ageing population and entering the role of informal caregiver generally marks an important life course transition. The adjustment to such transitions is considered important for the onset of sleep problems. Therefore, this study aims to establish how becoming a daily caregiver is associated with sleep problems, if changes in caregiving status are related to changes in sleep problems and how intersections with other social roles affect this association. Based on data from waves 1, 2, 4, 5 and 6 of the Survey of Health Ageing and Retirement in Europe (N=32,791), the analyses show how both current and former daily caregivers are more likely to report sleep problems than those not giving daily care. When change in sleep problems is assessed a transition to daily caregiving appears to be accompanied by increased sleep problems. Moreover, even individuals who ceased giving care experience more sleep problems than those who never gave care on a daily basis, which suggests a legacy of caregiving. No differences are found regarding employment status, but women who start giving care are more likely to experience sleep problems than their male counterparts.
Exchange Rates Fluctuations and International Trade in a Mono-product Economy: Nigeria’s Experience, 1986-2018

This study sought to examine the effects of Exchange Rate on the International Trade in a MonoProduct Economy: Nigeria’s experience 1986–2018 Nigeria has a large population and as a nation, she imports virtually everything including toilet tissues and toothpicks. In fact, in some quarters, the consumption of imported goods has become a status symbol. With few functional manufacturing firms, her major foreign Exchange earner being Crude Oil accounting for over 70% of her foreign exchange earnings has suffered consistent price decreases and even showing no signs of recovery. Holding to her inability to process sufficient quantities of the Crude for local consumption, a large chunk of the foreign Exchange earned is spent in importing processed Petroleum Products from other Countries. Furthermore, the Citizens’ uncontrollable and insatiable appetite for imported goods(ranging from food to fodder, to electronics, Ceramics and all sorts of building materials including raw materials, to automobiles and worst of it all Medical Tourism) including so many Original Research Article Kalu and Mike; SAJSSE, 7(2): 21-48, 2020; Article no.SAJSSE. 57675 22 ostentatious items has put further strain on her foreign exchange and by implication the Exchange Rate of the Naira. Ex post facto method was adopted In order to test the hypothesis, the researcher adopted Augmented Dickey Fuller, Vector Error Correction Model and co-integration tests. Adopting a VECM and Co-integration framework with particular focus on the Nigerian economy, the following findings were made: Nigerian Economy shared a long run co-integrating relationship with the studied international trade related variables, Nigerian economy adjusts at 81% to the shocks and dynamics of the exchange rate and its correlates and a causal relationship exists between export and exchange rate and all the studied variables in the block exogeneity form. It was recommended that: CBN should continue with the reduced Exchange Rate on Agriculture and other Manufacturing activities as this is capable of increasing Investment which will result in increased Foreign Exchange earnings through export of Agricultural products and even other made –in-Nigeria products, Firms should be licensed to build refineries for processing of Our Crude Oil, this will make refined petroleum Products available, and affordable thereby eliminating the endemic fraud embedded in subsidy payments. Provision of adequate infrastructure in the Country especially in the areas of Power and Medicare; this will go a long way in assisting manufacturing firms as well as reduce the cost of Medical Tourism.
Relationship betweenAcacia mangium × Acacia auriculiformis hybrids and their parents based on leaf and root anatomy characteristics

Acacia mangium×Acacia auriculiformishybrids do not always perform intermediate features of both parents. A study was conducted to observe the similarity of Acacia hybrid progenies to their parents based on anatomical features of leaf and root. Leaf and root samples were taken from each three sampled trees of Acacia hybrid and parent species selected on three growth superiority classes: superior, intermediate and inferior. The anatomical features were observed on leaf and root tissue specimens prepared through free-hand and non-embedding technique. Similarity and relationship indexes were determined using cluster analysis.The similarity index between the superior hybrid and female tree was higher than that ofthe male tree with similarity index value of 88.45% and 87.60% respectively. Based on the phenogram analysis, the parent species were clustered into two clearly separated groups with the distance of 86%. The superior and intermediate classes of Acacia hybrids tended to cluster into female parent group. Superior Acacia hybrids could be potentially produced by selecting the superior female parents as mother.
A CRITICAL DISCOURSE ANALYSIS OF MOHAMAD NASIR’S SPEECH

Discourse is a unit of language in which its form is longer than a sentence including the vast majority of everyday communication; in addition, it ussually employes specific kinds of language as well as infromation structures to deliver specific purposes. In order to identify the structure and purpose of a discourse, the present research employed Critical Discourse Analysis (CDA) to analyze an educational speech in May 2nd, 2016 delivered by the Indonesian Ministry of Research, Technology, and Higher Education, Mohamad Nasir in the celebration of the National Education Day of Indonesia. The result of the analysis showed how the speech was constructed in form of macrostructure, superstructure, and microstructure revealed how the social power was used by symbolic elites to invite all parties in educational field to join together in reforming educational system of Indonesia to be better than what had been conducted by previous partisans in the past.

Does asset location and concentration explain REIT IPO valuation?

Following recent developments in the asset pricing literature on geographic concentration, we complement classic theories based on information asymmetry and explain the short-run performance of REIT IPOs through an investor base mechanism. We analyze the U.S. market and show that issuers are more likely to underprice when a REIT is more geographically concentrated. In particular, by adopting an identification strategy of pre- and after-IPO returns, we find evidence for an investor base channel rather than a diversification discount channel. In addition, geographic portfolio concentration has a stronger impact on the initial returns of REIT IPOs than property type concentration. Finally, we find that lower deadweight costs at the time of an IPO weaken the influence of geographic concentration on initial returns. Our results are robust to the firm’s geographic concentration in economically defined regions, different measures of deadweight costs, the control of information environment of the portfolio and headquarters markets and to controlling for the REIT’s property type focus.
Sustainable procurement practices in the Brazilian chemical industry context

Sustainable procurement requires an understanding of the full impact of purchase throughout the entire life cycle of the product or service, irrespective of location. The aim is to investigate the adoption of sustainable procurement in some Brazilian chemical companies. Questionnaires were sent to professionals from the Brazilian Chemical Industry Association (ABIQUIM) and from thirty-seven associated companies. The results were used to elaborate empirical illustrations about sustainable procurement practices in the Brazilian chemical industry context. Although the companies did not have a prescriptive supplier selection model that incorporates social-environmental criteria, most companies had more restrictive standards than the legislation and they supported suppliers to improve their social-environmental performance. In addition, that actions related to social and environmental issues occur in policies and documents and are reflected through middle and upper management commitments. It indicates that there are some organizational directions to incorporate social and environmental questions. However, no materialization in actions along the procurement process.
Evaluating a land surface model at a water-limited site: implications for land surface contributions to droughts and heatwaves

<p>Land surface models underpin coupled climate model projections of droughts and heatwaves. However, the lack of simultaneous observations of individual components of evapotranspiration, concurrent with root-zone soil moisture, has limited previous model evaluations. Here, we use a comprehensive set of observations from a water-limited site in southeastern Australia including both evapotranspiration and soil moisture to a depth of 4.5 m to evaluate the Community Atmosphere-Biosphere Land Exchange (CABLE) land surface model. We demonstrate that alternative process representations within CABLE had the capacity to improve simulated evapotranspiration, but not necessarily soil moisture dynamics - highlighting problems of model evaluations against water fluxes alone. Our best simulation was achieved by resolving a soil evaporation bias; a more realistic initialisation of the groundwater aquifer state; higher vertical soil resolution informed by observed soil properties; and further calibrating soil hydraulic conductivity. Despite these improvements, the role of the empirical soil moisture stress function in influencing the simulated water fluxes remained important: using a site calibrated function reduced the soil water stress on plants by 36 % during drought and 23 % at other times. These changes in CABLE not only improve the seasonal cycle of evapotranspiration, but also affect the latent and sensible heat fluxes during droughts and heatwaves. The range of parameterisations tested led to differences of ~150 W m<sup>-2</sup> in the simulated latent heat flux during a heatwave, implying a strong impact of parameterisations on the capacity for evaporative cooling and feedbacks to the boundary layer (when coupled). Overall, our results highlight the opportunity to advance the capability of land surface models to capture water cycle processes, particularly during meteorological extremes, when sufficient observations of both evapotranspiration fluxes and soil moisture profiles are available. </p>
A comprehensive assessment of bus rollover crashes: integration of multibody dynamic and finite element simulation methods

Abstract Rollover crashes have the highest fatality rate and exhibit complex and unpredictable mechanisms in terms of vehicle-ground and vehicle-occupant interactions. The objective of this study is to evaluate the tilt table and modified dolly rollover (MDR) crash tests in terms of how these crash tests can represent those interactions and compare their results with two real-world rollover crashes. An application of combined dynamic and finite element (FE) simulations was presented to assess the cutaway bus rollover crash. First, the numerical models were validated against the experimental MDR test. Then, two real-world rollover crashes were simulated in PC-Crash to find the kinematics of the bus prior to the first vehicle-to-roof impact phase. Next, the impact phase of these real-world crashes was simulated using LS-DYNA and the results were compared with the two rollover crash tests. The FE simulations were conducted using a 2-point belted 50th Hybrid III FE model. The results of this study indicate that the common impact mechanism among these rollover scenarios was the impact between the bus’s roof corner (roof connection to the sidewall) and ground which caused lateral deformation patterns. Furthermore, unlike passenger cars where the vertical roof deformation can cause severe injuries in rollover crashes, the intrusion of the bus’s passenger compartment was not identified as a main source of injury. In addition, the highest head, neck, and chest injury risk were predicted during the MDR simulation where the ATD was partially ejected through the side window. Lastly, possible future works and limitations were explained.

The aim of this study is the search for ferments from microorganisms isolated from the sap of the oil palm. It consisted in determining, before and after 24 hours of fermentation, the physicochemical and microbiological parameters of palm wine using standard methods. The pH, the rate of reducing sugars and the dry matter levels decrease while the acidity, vitamin C and the water content increase after 24 hours of fermentation. The pH decreases from 3.560.01 to 3.240.01 in Dura palm wines with the Pisi Sab S10 microorganism, while in Pisifera wine this pH increases from 3.930.01 to 3.820.01 with Pisi Sab 30S3. The titrable acidities increase from 0.71%0.01 to 0.79%0.01 in the sap of the Dura palm with the Pisi Sab S10 microorganism, while in the wine of Pisifera the rate increases from 0.67%0.01 to 0.76%0.01 with the microorganism Pisi Sab 30S3. Reducing the levels of sugar decrease to minimum values. They increase from 86.340.02 to 42.050.01 mg/mL in the sap of the Dura palm with the Pisi Sab S10 microorganism, whereas in that of the Pisifera wine, the rate increases from 32.070.02 to Original Research Article Detto et al.; AJAAR, 13(4): 16-23, 2020; Article no.AJAAR. 57522 17 14.530.02 mg/mL with the Pisi Sab 30S3 microorganism. The level of alcohol increases to reach maximum values of 4.24%0.01 with the Pisi Sab S10 microorganism in Dura palm sap and 4.29%0.01 in Pisifera sap with the Pisi Sab microorganism. 30S3. The microorganism giving the best organoleptic qualities in the sap of the Dura palm is Pisi Sab S10 while that of Pisifera is Pisi Sab 30S3. These microorganisms thanks to their efficiencies could be used as ferments in the agro-food industries.
Does Media Exposure Affect Financial Reporting Quality Through Auditors?

We examine whether the media has an indirect corporate governance effect on financial reporting quality (FRQ) that operates through auditors. This occurs because greater media coverage can magnify an auditor’s business risk by exposing the auditor to more potential litigation and reputation damage if an audit failure occurs. We use a path analysis to examine the direct and indirect channels of media corporate governance. We find a positive association between media coverage and FRQ that is mediated by audit fees, and the results are stronger for firms with greater incentives to engage in earnings manipulation. In contrast, we find no evidence that the media has a direct corporate governance effect on FRQ. Our results show how the media’s corporate governance reach can be extended by auditors who care about how media coverage impacts their risk level.
