Isolation and identification of microbial species found in cocoa fermentation as microbial starter culture candidates for cocoa bean fermentation in Colombia.

Microbial activity involved in the cocoa beans fermentation process is essential to maintain and improve the organoleptic and nutritional qualities of chocolate; therefore, the aim of this investigation was to search and select microbial isolates with the potential to improve the quality of cocoa beans. Fermentation experimentswere conducted on farms located in Maceo (Antioquia), San Vicente de Chucurí (Santander), and Rivera and Algeciras (Huila), Colombia. Yeast, lactic acid bacteria (LAB), acetic acid bacteria (AAB), and mesophilic aerobic microorganisms were obtained from different fermentation batches. The growth of these microorganismswas tested in six treatments as follows: 50% cocoa pulp agar (CPA), high concentrations of glucose (10%), ethanol (5%), and acetic acid (7%), an acidic pH of 3.0, and a high temperature of 50oC for 24 h. The isolates with the highest growth were identified by 18S and 16S rRNA gene analysis, revealing a high diversity ofspecies associated with cocoa fermentation, including eight species of yeasts (Debaryomyces hansenii, Meyerozyma guillermondii, Wickerhanomyces anomalus, Pichia guillermondii, Pichia kudriavzevii, Trichosporon asahii, Candida parapsilosis, and Pichia manshurica), six species of LAB (Pediococcus acidilactici, Lactobacillus brevis, Lactobacillus plantarum, Lactobacillus farraginis, Lactobacillus rhamnosus, and Leuconostoc mesenteroides), four species of AAB (Gluconobacter japonicus, Acetobacter tropicalis, Acetobacter pasteurianus, and Acetobacter malorum/tropicalis), and three species of Bacillus spp. (Bacillusaryabhattai /megaterium, Bacillus subtilis, and Bacillus coagulans). In general, microbial populations increased in cocoa batches after 12 h of fermentation and decreased after 84-96 h. All the yeast isolates grew in 10% glucose and CPA, 85.7% in 5% ethanol, and 95% at a pH of 3.0. All the yeast isolates were affectedby 7% acetic acid and incubation at 50oC for 24 h. Eighty-five percent of the LAB grew in 10% glucose, 100% in 5% ethanol, 42.8% in CPA, 64% at a pH of 3.0, and 35.7% grew after being exposed to 50oC for 24 h; all were affected by 7% acetic acid. As for the AAB, 100% grew in 10% glucose, 71% in 7% ethanol, 100% grew in CPA, in 7% acetic acid, and at a pH of 3.0, while 100% were affected by incubation at 50oC. Three yeast isolates, W. anomalus, D. hansenii and M. guillermondii, three LAB isolates, P. acidilactici, L. brevis, and L. plantarum, and three AAB isolates, A. tropicalis, A. pasteurianus and G. japonicus, were selected as promising strains to be used in a microbial starter culture for cocoa bean fermentation to improve the organoleptic quality of cocoa.

Similarly, the highest AUDPC (1474.67%-days) and r (0.038292 units-1) and the lowest AUDPC (165.67%-days) and r (-0.004976units-1) were similarly calculated from unsprayed control and from Tilt 250 EC treated plots, respectively. Regarding yield and yield related traits; ANOVA has shown significant variations (P
COVID-19 AND THE NEED FOR THE USE OF DIGITAL GAME-BASED LEARNING FOR TEACHING MATHEMATICS AT THE SAUDI ELEMENTARY SCHOOLS

: The ongoing Covid-19 pandemic has further underlined of significance of technology for the future of education. In spite of the unprecedented development in education, teaching and learning of mathematics is dominated by the conventional teacher-centred methods of teaching particularly in Saudi elementary schools. However, with Covid-19 forcing changes in educational system throughout the world, technology must be put in place in ensuring that learners continue to learn regardless of such situations. The aim of this paper is to demonstrate the need of the use of digital game-based learning for the teaching of mathematics at the Saudi elementary schools. The paper uses qualitative in-depth interviews as the paper’s method of data collection to ascertain the need (or lack of it thereof) of adopting digital game-based learning for the teaching of mathematics at the elementary level. A total of 16 interviews were carried out which were thematically analyzed with the aid of NVivo software application. Findings of the paper revealed that the teachers believe that there is indeed need for the use of digital game-based learning for the teaching of arithmetic at the elementary school as it will improve methods and help pupils learn in a better and faster ways, combine learning, gaming and technology, and eliminate boredom usually students associate with mathematics learning. The paper concluded that mathematics teachers as well as students are in need of a radical approach that reduces boredom and makes the subject of mathematics appealing to learners .
Review: Genetic Alterations of Hodgkine's Lymphoma

Lymphoma refers to cancer that developed in the lymphatic system. This type of tumor cause swelling in the lymph nodes and other parts of body. There are 35 different type of lymphoma recognized by WHO,five of them are belong to Hodgkin , s lymphoma(HL) and other subtypes belong to non Hodgkin lymphoma. Approximately 85% of lymphoma incidences are non-Hodgkin‘s disease and 15% are Hodgkin lymphoma. Early epidemiologic data suggested that HL develops among persons with a delayed exposure to a ubiquitous infectious agent, Epstein-Barr virus (EBV). A sound of biological basis association has been established between the genetic regions and risk of HL including some chromosomes and genes such as chromosomes 2, 6, 8, and 10 and REL and GATA3 genes. In HL there are no known specific simple genetic aberrations that would appear to be necessary for the malignant transformation. Alterations of chromosomes 2p, 3q, 6q, 7q, 9p, 13p, 14p and 17q are found more frequently than expected. Several breakpoints are detected non-randomly in HL, including 3q27, 6q15, 7q22, 11q23, 14q32, but translocation partners have not yet been identified. FISH studies performed with these samples led to the identification of gene amplifications, i.e. amplifications of the JAK2 gene on 9p23–p24 and the MDM2 gene on 12q14.
Does digitalization boost companies‘ new product launch success?

Digitalization and new product launch are two important topics which have been proved to have large input on companies’ success. Digitalization, because it can boost productivity, diminishes cost and raises effectiveness. New product launch, because innovation success guarantees high product margins and helps to avoid existencethreatening price competition in commoditized product markets. However, regarding shorter product life cycles, the ability to innovate and launch new products successfully, becomes an evident driver of companies’ success. Can digitalization with its described effects help to raise new product launch success? Are companies who obtain a higher level of digitalization degree, more successful concerning new product launch results? Although this question is a relevant topic to marketing and strategic management, there has not been research on that topic. Thus, research on that subject would close a relevant gap in science. In that sense, the objective of this article is to reveal the link between digitalization and new product launch success. This question is highly relevant before the background of the fourth industrial revolution, driven by the digitalization of business. Nevertheless, this specific question has never been asked. Also, no construct exists which allows to operationalize and measure the amount of the digitalization degree related to those digitalization measures that are relevant for new product success (= the relevant digitalization degree). This study is a first attempt to open the new field of links between digitalization and new product success. Therefore, the correlation between new product launch success and digitalization degree of German B2B traders has been inspected on the basis of an empirical survey.
INTEGRATION OF THE CONCEPT OF YIELD MANAGEMENT INTO THE MARKETING POLICY OF TRAVEL AGENCIES IN ROMANIA

This analysis starts from the idea according to which the activity of travel agencies in Romania significantly developed in the last few years, fact which determines with certainty a series of modifications of the proper course of their activity, of management and marketing processes. The present context caused by the evolution of SarsCoV-2 pandemic reveals, maybe more than ever, the relevance of the integration of the concept of yield management into the marketing policy of travel agencies, through the complementarity analysis between the elements of marketing mix and yield management. Interviewing the top-management from two tour operator travel agencies, representative on the national market, emphasizes the implementation of some management systems adapted mainly to their own organizational practices, based on using booking platforms (B2B and B2C), offering Early Booking and Last-Minute packages, overbooking and cost optimization. Although organization management and marketing policy are part of the regional tourism market dynamics, the new macroeconomic tendencies of the year 2020 need a strategic rethinking which implement, at least partially, the yield management processes, by relating them to the marketing mix where the central elements are market segmentation, reduction of demand and price flexibility according to the market demands.
Outbreak of Ralstonia Mannitolilytica Infection at a Tertiary Care Oncology Center in South India: A Case Series

Introduction: Ralstonia Mannitolilytica (RM) is a rare opportunistic pathogen capable of causing a serious infection in immunocompromised patients. It is ubiquitous in nature and a frequent contaminant of water supplies. RM infection in cancer patients may have serious implications as they are already susceptible due to underlying malignancy, treatment related immunosuppression, malnutrition and prolonged presence of indwelling central catheters. In this study, we report a case series of RM infection with focus on clinical characteristics, management and patterns of antibiotic sensitivity. Methods: This case series includes 17 cancer patients admitted at Healthcare Global oncology hospital, Bangalore, presenting with fever and/or chills between 22nd February 2020 to 5th May 2020, who had a positive blood culture and/or a chemoport/PICC/central venous catheter (CVC) tip culture positive for RM species.Results: Among all patients, RM was grown from the blood sample of 12 patients having an indwelling chemo-port, 4 patients with PICC line and 1 patient with a central venous line. All patients had a positive blood culture for RM, and two patients had a positive tip culture in their chemo-port and PICC line respectively. Antibiotic treatment includes cefoperazone-sulbactam for 10 patients, ceftazidime for 4 patients, meropenem for 2 patients and ceftriaxone for 1 patient. All 17 patients recovered from the infection without any complications. After 48 hours of incubation, no growth of Ralstonia was reported from any of the current environmental or pharmaceutical water samples. Conclusion: RM may be capable of causing serious infections in cancer patients as they are already immuno-compromised. Furthermore, RM may serve as an effective quality indicator of water and therapeutic supplies. Healthcare professionals should adhere to infection control policies, monitor outbreaks of unusual pathogens and study the emergence of pattern for antibiotic resistance.
Challenges in Creating Business Value from Health Information Systems (HIS): A Hybrid Fuzzy Approach

For the last three decades, research on Information Technology Business Value (ITBV) has highlighted how organizations can create greater value from IT investments in different industries, including the healthcare sector. There has been some research investigating the business value of Health Information Systems (HIS). However, the current body of knowledge regarding the challenges in front of proper business value realization of these systems is limited. This study investigates the challenges of HIS business value creation using a combination of the Fuzzy Analytic Hierarchy Process (FAHP) and fuzzy Decision-making Trial and Evaluation Laboratory (DEMATEL). First, this study reviews the literature to identify the main challenges in the field. The outcome of this step revealed three main categories and 22 challenges, including technological (ten challenges), organizational (eight challenges), and environmental (four challenges). Then, this study first uses FAHP to evaluate the weighting for each criterion and then adopts the fuzzy DEMATEL method to establish contextual relationships among those criteria. We find out that technological challenges are the most crucial dimension. Moreover, we observed that “infrastructure costs” has the highest priority. Under the technological dimension, “maintenance costs” and “systems compatibility” challenges are the most critical since they are in the cause area and directly influence the HIS outcomes. Under the organizational dimension, “Change in strategic objectives” is the most important challenge. Moreover, “inter-departmental coordination”, “training costs”, “proficiency”, and “users’ knowledge” are affected by each other as well as influenced by the net causes. The outcome of this study shows that to handle HIS business value creation challenges, healthcare executives should start with infrastructure costs, maintenance costs, and systems compatibility challenges.
Explicit teaching of questioning in math methods course: Preservice teachers’ attempts to ask probing questions

After an explicit unit of core activities on questioning, preservice teachers (PTs) completed an assignment to select a problem-solving task, anticipate student solutions, and plan probing questions. After analyzing PTs’ work, we discovered that, although most PTs planned probing questions, many also planned questions focused on information or procedures. Next steps include exposing PTs to probing questions focused on meanings, context, or representations.
Numerical Simulation of Free Convection in a Three-Dimensional Enclosure Full of Nanofluid with the Existence a Magnetic Field

A numerical analysis was performed to study the influence of a magnetic field in free convection in a cube full with nanofluid. To solve the equation, we appeal to finite volume method. The SIMPLEC algorithm is used for pressure-velocity coupling. All walls are adiabatic, except for the left and right walls that are heated differently. The effects of the Rayleigh and Hartmann numbers, as well as the volume fraction of nanometric particles were studied. Results are conveyed in the form of isotherms, streamlines, velocity curves and Nusselt numbers. It has been shown that as the percentage of nanoparticles increases and the number of Rayleigh increases, heat transfer improves. Hartman number has considerable influence on hydrodynamic and thermal field.
Optimization of Synthesis Conditions of Ni/SBA-15 Catalysts: Confined Nanoparticles and Improved Stability in Dry Reforming of Methane

Despite its economic and environmental advantages, the dry reforming of methane using supported Ni-based catalysts remains challenging due to problems of metal particle sintering and carbon deposition, which lead to loss in catalytic activity. In this study, different silica supports, containing 5 wt% nickel, were prepared and characterized by N2 sorption, XRD, TPR, and TEM/SEM, in addition to Raman and TGA/MS for the spent catalysts. Different synthesis conditions were thus varied, like nickel deposition method, nature of nickel precursor salt, conditions for thermal activation, and nature of support. The results showed that enhanced metal dispersion, good confinement, and efficient stabilization of the active phase inside the pores can be achieved by using a well-structured mesoporous support. Moreover, it was demonstrated that carbon resistance can be improved when small nickel particles are well confined inside the pores. The strategies that affect the final dispersion of nickel particles, their consequent confinement inside (or deposition outside) the mesopores and the resulting catalytic activity and stability include mainly the application of hydrothermal treatment to the support, the variation of the nature of nickel precursor salt, and the conditions for thermal activation. General guidelines for the preparation of suitable Ni-based catalysts highly active and stable for dry reforming of methane (DRM) are thus presented in this work.
Measuring Solar Differential Rotation with an Iterative Phase Correlation Method

A reliable inference of the differential rotation rate of the solar photosphere is essential for models of the solar interior. The work presented here is based on a novel iterative phase correlation technique, which relies on the measurement of the local shift, at the central meridian, between two images separated by a given time interval. Consequently, it does not require any specific reference features, such as sunspots or supergranules, nor extended observations spanning several months. The reliability of the method is demonstrated by applying it to high spatial and temporal resolution continuum images of the solar photosphere, at 6173 Å, acquired by the Solar Dynamics Observatory Helioseismic and Magnetic Imager over one complete Carrington rotation. The data selected covers the time period of 2020 January 1 to February 2. The method was applied to one day, and to the full time interval. The differential rotation rate derived using this feature-independent technique yields values that fall in the middle of the range of those published to date. Most importantly, the method is suited for the production of detailed rotation maps of the solar photosphere. It also enables the visual and quantitative identification of the north–south asymmetry in the solar differential rotation rate, when present.
The Role of Project Culture in Achieving The Performance of Indonesian Toll Road Projects

The influences of culture at different levels such as national culture, organizational culture and professional culture have become one of the most research topics in construction management. Understanding cultural issues at the project level and their impact on the performance of the construction project is required for the construction sector as a project-based industry. The purpose of this paper is to determine the perceptions of the Indonesian construction practitioners about the impact of the project culture dimensions on the performance of toll road projects. Under the case study umbrella, this research reports two toll road projects whereby the project culture dimensions of these largescale projects were seen to impact significantly on project performance. Furthermore, this research demonstrates the reliability of using the project culture framework developed by Zuo et al. (1) to evaluate project culture dimensions in the context of Indonesian toll road projects.
Fractal Aspects Of Epidemic Spread

The main properties of a fractal model to describe the epidemic spread of diseases are discussed. The most important features of the epidemic process that leads to the conclusion of an underlying fractal structure are analyzed, and the meaning of the parameters of the model are investigated. It is shown that the existence of a fractal mechanism in the epidemic evolution leads to a simple relation between time interval for the epidemic spread and the population size. It is shown that the contamination rate varies with the population size. The relevant differences between the SIR model and the fractal model are discussed.
Nanoscale Porous Materials for Water Treatment: Advances and Challenges

Micro and mesoporous materials have been a great focus of scientific and technological interest from almost half of the century. This is due to its large surface area and extremely high porosity which offers huge potential for its application in a variety of fields, ranging from materials science to biomedical research. International Union of Pure and Applied Chemistry (IUPAC) has classified porous materials into 3 groups (Davis, 2002): (a) Microporous materials (MiPMs), having pore diameters less than 2 nm; (b) mesoporous materials (MePM), having pore diameters ranging from 2 50 nm; and (c) macroporous materials (MaPM), having pore diameters larger than 50 nm. The term nanoporous materials (NPM) have been used for those porous materials with pore diameters of < 100 nm. Hence, the NPM is defined as a material having a pore size < 100 nm of any solid structural components whether or not the structure itself is nano size (i.e., < 100 nm). Hence, it covers porous materials lies in MiPMs, MePM and MaPM. Table 11.1 summarizes the classification of porous materials based on pore size.
Design, delivery and evaluation of a bioinformatics education workshop for 13-16-year-olds

ABSTRACT Bioinformatics is the use of computers in biology, particularly to analyse DNA and protein sequences and associated data. Bioinformatics has become crucial to most areas of life sciences research. However, bioinformatics education has not kept up with the pace of these advances. To help address this problem, we have designed an open-access bioinformatics workshop for secondary school biology pupils. The workshop is linked to the curriculum in Scotland, addressing learning objectives for Scottish Qualifications Authority Higher Biology and Human Biology. Furthermore, it aims to inspire pupils more generally and includes critical evaluation of evidence as a more generic skill. We delivered this workshop to biology pupils of seven schools in Scotland and conducted evaluations of pupil and teacher feedback. Quantitative pupil and teacher feedback suggests the workshop is useful and enjoyable, with no statistically significant difference between pupils identifying as female and pupils identifying as male. Qualitative responses suggest the workshop gives an increased knowledge of the field of bioinformatics and its importance in everyday life, and that pupils enjoy working in groups. Teachers also highlight the importance of hands-on experience in the classroom. We conclude the workshop is successful in its aims and is suitable for wider deployment.
