CHARACTERIZATION OF ZINC OXIDE NANOPARTICLES SYNTHESIZED BY OLEA EUROPAEA LEAVES EXTRACT (PART L)

The current study was aimed to synthesized zinc oxide nanoparticles (ZnONPs) using aqueous extract of olive leaves (OLE), which is very simple and eco-friendly method. ZnONPs were formed by dissolving of OLE in zinc oxide solution with adjusted pH to 12. Zinc acetate dehydrate reduced to ZnONPs during mixing with OLE associated with change of the color solution from white to pale yellow color within a few minutes. The synthesized OLEZnONPs were separated by centrifugation (4000rpm/ 5min) , then characterized by Fourier Transmission Infrared Spectroscopy (FT-IR), X-ray diffraction (XRD) and Field emissionScanning Electron Microscopy (FE-SEM) methods. The results of FT-IR showed that the functional group related to Zn-O at (433.98 to 416.67 cm _1 ), whereas X-RD at 2 theta diagnose the type of oxide formation as ZnO and determined particle size in range (20 – 30 nm). Besides, SEM image was showed the presence of hexagonal shape of ZnO nanoparticles (42.87nm). Therefore, the biogenic synthesis of zinc oxide nanoparticles using Olea Europaea leaves was simple, low coast, can be an alternative to chemical synthesis and the possibility of using in biomedicine field
M ITIGATING A DVERSARIAL T RAINING I NSTABILITY WITH B ATCH N ORMALIZATION

The adversarial training paradigm has become the standard in training deep neural networks for robustness. Yet, it remains unstable, with the mechanisms driving this instability poorly understood. In this study, we discover that this instability is primarily driven by a non-smooth optimization landscape and an internal covariate shift phenomenon, and show that Batch Normalization (BN) can effectively mitigate both these issues. Further, we demonstrate that BN universally improves clean and robust performance across various defenses, datasets, and model types, with greater improvement on more difﬁcult tasks. Finally, we conﬁrm BN’s heterogeneous distribution issue with mixed-batch training and propose a solution.
The Effect of Incentivized Electronic Word-of-Mouth (EWOM) on Consumer Purchase Intention

Objective: Social media has a strong impact as a reference for consumers in getting information about the product. Electronic word-of-mouth (eWOM), which is usually delivered by social media, is still the most secure advertising media. This study provides information about incentivized eWOM on purchase intention and other factors that can affect consumers. Research Design & Methods: The method used in this research is the quantitative method with an associative approach. Descriptive analysis and structural equation modeling were used to measure the influence of these variables. Findings: The results showed that the incentivized eWOM had a significant effect on purchase intention but had no impact on the company’s brand awareness. Meanwhile, the attractiveness of advertising messages has no significant effect in influencing purchase intention but has a significant effect on the company’s brand awareness. Implications & Recommendations: Although this research give contributions to the e-WOM literature, several limitations and future research suggestion deserve mentions. Further research can examine the relative effectiveness of nonmonetary incentives. Contribution & Value Added: Researchers have provided input and suggestions to SMEs to optimize incentivized eWOM to increase consumer purchase intention.
Evaluation of indigenous fungal entomopathogens and aqueous leaf extract of Annona muricata against Polyphagotarsonemus latus infesting Jatropha curcas in Indonesia

Puspitarini RD, Afandhi A, Fernando I. 2021. Evaluation of indigenous fungal entomopathogens and aqueous leaf extract of Annona muricata against Polyphagotarsonemus latus infesting Jatropha curcas in Indonesia. Biodiversitas 22: 2648-2655. The broad mite Polyphagotarsonemus latus (Banks) (Acari: Tarsonemidae) has been known to cause a great deal of injury on Jatropha curcas (L.) plantation in Indonesia. Isolation of indigenous fungal entomopathogens from rhizosphere soils, followed by pathogenicity assay was conducted to find an effective isolate for controlling P. latus. Additionally, the potential combination of the selected isolate and soursop (Annona muricata L.) aqueous leaf extract (SLE) was investigated. A total of 24 isolates were obtained by using the insect bait method. Four fungal isolates, namely Paecilomyces sp. 1. , Lecanicillium sp. , Beauveria sp. , and Fusarium sp. 1, showed high conidial viability and were chosen as representatives to assess their pathogenicity against P. latus. Among the tested isolates, Beauveria sp. which had the highest conidial viability among the tested isolates, needed a shorter period to completely kill the tested mites. However, the compatibility test revealed the deleterious effect of SLE on Beauveria sp. SLE at all concentrations showed a very toxic effect on the fungus, therefore the two must be applied separately. Our results provide useful information on the effectiveness of indigenous entomopathogenic fungi Beauveria sp. and aqueous leaf extract of A. muricata as an alternative tool to control the broad mite P. latus on the J. curcas plantation.
Pandemic-response adenoviral vector and RNA vaccine manufacturing

Rapid global COVID-19 pandemic response by mass vaccination is currently limited by the rate of vaccine manufacturing. This study presents a techno-economic feasibility assessment and comparison of three vaccine production platform technologies deployed during the COVID-19 pandemic: (1) adenovirus-vectored (AVV) vaccines, (2) messenger RNA (mRNA) vaccines, and (3) the newer self-amplifying RNA (saRNA) vaccines. Besides assessing the baseline performance of the production process, impact of key design and operational uncertainties on the productivity and cost performance of these vaccine platforms is quantified using variance-based global sensitivity analysis. Cost and resource requirement projections are computed for manufacturing multi-billion vaccine doses for covering the current global demand shortage and for providing annual booster immunisations. The model-based assessment provides key insights to policymakers and vaccine manufacturers for risk analysis, asset utilisation, directions for future technology improvements and future epidemic/pandemic preparedness, given the disease-agnostic nature of these vaccine production platforms.

Tahfiz Students’ Experiences in Memorizing the Qur’an: Unveiling Their Motivating Factors and Challenges

This qualitative case study explores the factors behind Tahfiz secondary school students’ motivation to undertake the challenging task of memorizing the Qur’an and the challenges they experienced. The participants were six (6) Tahfiz students (three boys and three girls), aged between 15 and 17, who were enrolled in the Tahfiz Al-Qur’an program in two public secondary schools in Gombak and Bangi. The participants were selected by their teachers through purposeful sampling and had been engaged in Qur’an memorization for at least 2 years at the onset of the study. In-depth, semi-structured one-on-one interviews were conducted to examine their views about the factors that motivated them to memorize the Qur’an and the difficulties they faced. The findings pointed to three distinct categories of motivating factors: the students themselves, teachers and parents. In particular, parental guidance and advice were the most influential elements in students’ motivation to memorize the Qur’an. Among the challenges faced were time constraint, inability to remember verses, strict disciplinary rules and external noise that made the memorizing task difficult. In general, this study has shown the instrumental role of motivation in influencing Tahfiz students' memorization of the Qur’an.
Price of Competition and Fragmentation in Ride-Sourcing Markets

This paper proposes a general model for describing the equilibrium state of a ride-sourcing market with an arbitrary number of platforms competing with each other. As the number of platforms increases, the market changes from monopoly to duopoly, oligopoly, and finally perfect competition, bringing about two different effects on system efficiency. On the one hand, like other service markets, competition in the ride-sourcing markets prevents a monopolist platform from greedily maximizing its own profit by distorting its operating strategies from socially efficient levels. On the other hand, competition between platforms leads to market fragmentation, thereby increasing matching frictions and passengers’ waiting time. In this paper we develop a game-theoretical model to determine the solutions of a Nash equilibrium in a competitive ride-sourcing market, at which no platform can increase its profits by unilaterally changing its own strategy. Then we try to quantify the price (efficiency gain or loss) of competition and fragmentation by establishing an upper bound of the inefficiency ratio, i.e., the ratio of social welfare under a social optimum to social welfare under a competitive Nash equilibrium. We show that the results of market equilibrium, including the inefficiency ratio, are jointly governed by the degree of market fragmentation and competition among platforms. In particular, we find that some key market measures, such as consumer surplus, platform profits, social welfare, display diverse trends of changes with respect to the number of platforms, as the matching technology exhibits increasing, constant, and decreasing returns to scale.
Do COVID-19 Lockdowns Affect Deforestation?

The COVID-19 pandemic and associated government responses halted economic activity across the world. The environment benefited from the reduced pollution in urban areas. However, there is no evidence on the pandemic's environmental effect away from cities, specifically on deforestation. \textit{A priori}, the effect is unclear: deforestation might decrease with the restrictions on economic activity. But it might increase, given the drying up of alternative income sources. I combine bi-weekly data from 70 countries covering the entire world's tropical forest with the dates each country introduced lockdown restrictions. Using difference-in-differences strategies, I find that the average effect of lockdowns in deforestation is not distinguishable from zero. However, the effect on deforestation does vary by the share of lockdown vulnerable GDP and the level of government effectiveness. These results highlight the importance of alternative income sources and state capacity for policies that could reduce deforestation.
Prevalence and Risk Factor of Chronic Rhinosinusitis and the Impact on Quality of Life in Students of the Medical Faculty Christian University of Indonesia in 2018

Chronic Rhinosinusitis (CRS) is an inflammation of nasal mucose dan paranasal sinuses with ≥ two symptoms, one of which should be nasal blockage/ obstruction or nasal discharge (anterior/ posterior nasal drip) that happened for ≥ 12 Weeks. CRS affects 515% adult population in Europe and the United States of America, with a prevalence of 24% that doctors have diagnosed. The risk factors of CRS that quite often happened on CRS is allergic rhinitis. CRS also often happened in women. CRS also impact the patient's quality of life. This study aims to know the prevalence and risk factor of CRS and the impact on quality of life on 160 students of the Medical Faculty Christian University of Indonesia uses a validated questionnaire and SNOT-22 questionnaire.

The correlation of allergic history suspect with CRS is proven by a statistic test using chi-square with results P=0,003 (P>0,05) with a majority of the distribution is allergic rhinitis are 60 students (90,1%). All respondents answered that CRS impacts their quality of life with most of the symptoms: nasal blockage/ obstruction and 36 students (57,7%).
Modeling of continuous-flow bioreactors with a biofilm with the use of orthogonal collocation on finite elements

ABSTRACT The paper discusses mathematical modeling of two types of continuous bioreactors, a continuous stirred tank bioreactor (CSTBR) and a tubular bioreactor with biofilm on inner walls. The method of orthogonal collocation on finite elements (OCFE) was used for the modeling of a microbiological process occurring in the biofilm. Single-substrate Monod and Haldane kinetic models, and double-substrate Haldane–Monod kinetic model were used. The accuracy of the OCFE method was evaluated by comparison with the solution obtained using shooting method (SM). Profiles of substrate concentration, biofilm effectiveness factors, steady state-branches of CSTBR and distribution of substrate concentrations and biofilm thickness along the length of the tubular bioreactor were determined. Steady-state branches of the CSTBR were compared with experimental results from the literature. It was shown that the mathematical model gives good agreement. The efficiency of the OCFE method was demonstrated even for very steep gradients of concentrations in the biofilm.
Analysis of formaldehyde content in salted fish at Ciroyom market, Bandung City, Indonesia

ARTICLE INFO Salted fish is one of the processed fish products that are in great demand by the people of Indonesia. This type of preparation has good durability with natural processes. However, there are some cases that use chemicals as preservatives, such as formaldehyde. This study aims to determine the formaldehyde content in salted fish that is traded in the market in Indonesia. This research is descriptive and the samples were randomly taken from Ciroyom Market, Bandung City, Indonesia. The data were analyzed qualitatively to find out the physical characteristics of the salted fish. In addition, a quantitative analysis was also carried out to determine the level of formaldehyde present in salted fish using a UV-Vis spectrophotometer at a wavelength of 520 nm. The results of the analysis showed that 4 of the 15 samples tested contained formaldehyde with a concentration of 0.033 – 0.482 ppm. The characteristics of these samples physically also have similarities with the characteristics of fish containing formaldehyde, which are bright white and hard textured.

Do Cash Flow and Accounting Profit Information Affect Stock Prices?

This study aims to determine the effect of cash flow statement information and accounting profit on stock prices. The object of this research is a food & beverage sub-sector manufacturing company listed on the Indonesia Stock Exchange in 2015-2019. The sampling technique used a purposive sampling technique with ten samples of financial statements that meet the criteria. The analysis technique uses the help of Partial Lease Square (PLS) with SmartPLS 3.0 Software. The study results show that the Cash Flow Statement of operating and funding information does not affect stock prices. On the other hand, information on the investing Cash Flow Statement and accounting profit affect stock prices. The more investors intend to buy or keep shares; the stock price will increase. Vice versa, if the number of investors who intend to sell or release shares increases, the share price will decrease. Based on these results, it is suggested that investors in deciding on selling or buying stock shares may pay more attention to the information from investing cash flow and accounting profit.
Correlation of neutrophil lymphocyte ratio with HbA1c in patients of type 2 diabetes mellitus

Background: Neutrophil lymphocyte is an indicator of subclinical inflammation. Type 2 diabetes mellitus is associated with chronic low-grade inflammation. One of the novel inflammatory markers is hemogram derived neutrophil to lymphocyte ratio. There are very few studies which are directly accessing the relation between NLR and HbA1c, so in the present study our aim to correlate neutrophil lymphocyte ratio with glycemic control in patients having type 2 diabetes.Methods: Hospital based observational cross section study was carried out at department of medicine, Pt JNMMC and Dr BRAM Hospital, Raipur, between September 2018 to August 2019. 105 patients with type 2 diabetes mellitus according to ADA criteria who were aged more than 18 years were included in the study. Relevant investigation and complete blood count were performed. Microsoft excel and SPSS version 25 were used for collection and analysis of the data, p<0.05 was considered as significant.Results: Out of 105 patients who were given the consent for the study, the ration of male is to female was 1:0.98, mean age of all the patients was 51.77±10.56 years, mean neutrophil lymphocyte ratio among the patients was 6.30±2.646, HbA1c count more than ≥9 was 54 (51.27%). NLR had a positive correlation with HbA1c and was found to be an independent predictor of poor glycemic control in patients with type 2 diabetes mellitus.Conclusions: Increased NLR is associated with elevated HbA1c and poor glycemic control. Type NLR should be used as a marker of diabetic control level in addition to HbA1c in type 2 diabetic subjects.
The Production and Optimization of Bioethanol from Oil Palm Fronds: A Source of Renewable Energy

Environmental issues and the desire to be less dependent on fossil fuel have intensified research efforts towards the production of biofuels since they are a safe and clean alternatives to fossil fuels. However, the cost of carbohydrate raw materials has become a limiting factor for large-scale production, hence the need to source for low cost feedstock. This study analyzed the processes and optimization involved in the production of bioethanol from oil palm fronds from Okada, Edo State, Nigeria, as an alternative source of energy. In this study, solidstate fermentation was carried out for the production of fermentable sugars from oil palm fronds inoculated with local isolate Aspergillus niger, the results from this analysis show that the pretreatment of oil palm frond substrate using Aspergillus niger was effective, The process was effectively optimized within the confines of the following parameters; temperature X3 (36-42oC), pH, X2 (5.1-5.7), inoculum, X4(4-22) and fermentation time X1 (0-36hr), an optimum Ethanol yield Y, of 110% was obtained.
Spillover Effects of Bank Bailouts

Do public supports to banks generate spillover effects and influence the financial stability during banking crises? By using a hand-collected dataset in Europe from 2007 to 2017, we adopt a dynamic difference-in-differences approach and show a spillover effect when the bailout is not associated with conditions: when rescued banks receive a bailout without any restricting condition, their competitors have incentives to worsen the quality of their loan portfolios by leading a reduction in their competitors’ margins. We also run an event study and show that these policies attract negative abnormal returns from investors.
Multiprofessional approach for class III malocclusion rehabilitation with autogenous calvarial bone graft followed by Le Fort 1 osteotomy and implant-supported prostheses – case report

Extensive treatments can eventually be challenging. Even more so when the patient has limitations such as extensive tooth loss and skeletal changes, including overgrowth of the lower jaw. When indicated, these treatments tend to discourage patients due to the history of previous failures. Therefore, in addition to an interdisciplinary dental team composed of oral and maxillofacial surgeons, and prosthodontists, a nutrologist, a speech therapist, and a psychotherapist were involved in the treatment of this case. A 52-year-old female patient, Angle Class III malocclusion, with few teeth and extensive maxillary bone loss, attended the dental clinic of the Brazilian Association of Dentistry in Uberlândia. The treatment involved reverse planning, extraction of the dental remnants, calvarial bone grafting, placement of 6 titanium implants (Neodent) in the maxilla (upper jaw) and 5 in the mandible (lower jaw), orthognathic surgery, and installation of implant-supported fixed complete dentures in both jaws. Furthermore, psychotherapeutic and nutrologist’s interventions were necessary during the dental treatment, concluding the treatment with speech therapy. Within the limitations of this case, the multidisciplinary approach proved to be efficient. It promoted the reestablishment of the stomatognathic system functions without compromising nutrition during the periods when it was impossible to wear prostheses for better healing of the tissues.
