Polyamorphism of liquid silica under compression based on five order-parameters and two-state model: a completed and unified description

ABSTRACT The polyamorphism of liquid silica (SiO2) at 3200 K and in a wide pressure range is investigated by molecular dynamics simulation. Results show that the structure of liquid SiO2 consists of five order-parameters that do not depend on compression. Three order parameters that relate to the short-range order are SiOx coordination units (x = 4, 5, 6) and two order parameters that relate to the intermediate-range order are OSi2 and OSi3 linkages. The structure of liquid silica under compression can be described by the two-state model: low-density and high-density states. The low-density state is formed by clustering of OSi2 linkages (in the low-density state, the short-range order (SRO) is mainly characterized by SiO4 coordination units), conversely, clustering of OSi3 linkages will form high-density state (in the high-density state, the SRO is mainly characterized by SiO5 and SiO6 coordination units). Under compression, in the liquid silica co-exist two phases: low-density and high-density phases. The size of phase regions significantly depends on compression.
GENETIC DIVERSITY AMONG THYMUS SPP. USING RAPD AND ISSR MARKERS

his investigation was carried out to assess the relationships among three Thymus species; two wild species (Thymus capitatus and Thymus decussatus) and a cultivar (Thymus vulgaris). Two molecular markers were used to determine the genetic relationships among them; random amplified polymorphic DNA (RAPD) and the inter-simple sequence repeats (ISSR) markers techniques. The results suggest that RAPD marker is the best choice for the evaluation of diversity and the genetic relationships between two wild Thymus species with high accuracy, which revealed 224 DNA bands detected across 15 primers with high polymorphism than ISSR, which revealed 336 DNA bands. The genetic relationship among Thymus species based on molecular data was developed using a dendrogram constructed by UPGMA cluster analysis. Conservationist may use the information of the present study to make effective decisions regarding the global protection and management of Thymus species in Egypt.
IN TIMES OF CLIMATE CHANGE

INTERNACIONAL WORK GROUP FOR INDIGENOUS AFFAIRS Eliminating pieces of the jigsaw in order to blur the distinction between legal and illegal timber will only backfire. The new forest authorities in the country seem to have understood this situation and now appear to be working in this direction. The long-term vision –implying a sustainable use of the natural forests and resources for the sake of future generations, the environment and the planet– will hopefully win over the short-sighted one – allowing the industry and exporters to do what they want now, at the cost of environmental destruction and violations of human rights. Peru must understand that, for the sake of its forests, but also for the sake of its timber industry, transparency is the only route.
Alternative Language Assessments in the Digital Age

this article explores how the use of information communication technology (ICT) can assist English language instructors transform traditional assessment to better inform their teaching practice and to gain valuable insight into the actual academic progress of their English learners in a more valid and accurate fashion. Many recent publications have shown the potential ways and benefits of integrating ICT into the English teaching practice in an attempt to personalize learning and transform the learning–teaching experience for both students and teachers. Nevertheless, not as many have been devoted to discussing practical alternative ways of assessment of students’ performance, which is a much–needed missing link in the process of truly transforming the 21 st century digital age learning experience. A true digital age learning environment moves away from focusing on preparing language learners for standardized language tests to creating authentic assessments reflecting the learning experiences carried out inside and outside the classroom. This article aims to transform the way English language teachers view and design alternative assessments featuring ICT tools to help students demonstrate their success in English learning in varied and multiple ways.
Weighing the Evidence: On Relationship Types in Microservice Extraction

The microservice-based architecture – a SOA-inspired principle of dividing systems into components that communicate with each other using language-agnostic APIs – has gained increased popularity in industry. Yet, migrating a monolithic application to microservices is a challenging task. A number of automated microservice extraction techniques have been proposed to help developers with the migration complexity. These techniques, at large, construct a graph-based representation of an application and cluster its elements into service candidates. The techniques vary by their decomposition goals and, subsequently, types of relationships between application elements that they consider – structural, semantic term similarity, and evolutionary – with each technique utilizing a fixed subset and weighting of these relationship types.In this paper, we perform a multi-method exploratory study with 10 industrial practitioners to investigate (1) the applicability and usefulness of different relationships types during the microservice extraction process and (2) expectations practitioners have for tools utilizing such relationships. Our results show that practitioners often need a "what-if" analysis tool that simultaneously considers multiple relationship types during the extraction process and that there is no fixed way to weight these relationships. Our study also identifies organization- and application-specific considerations that lead practitioners to prefer certain relationship types over others, e.g., the age of the codebase and languages spoken in the organization. It outlines possible strategies to help developers during the extraction process, e.g., the ability to iteratively filter and customize relationships.
Cross-Sectional Studies Reveal A Fluctuating But Endemic Malaria Transmission

The effects of Malaria coupled with the yearly climatic changes and variations of certain contributing factors embedded in the various ecological zones in Nigeria has continued to sustained the fluctuating indices of disease transmission and its endemicity. To understand these indices as a means of generating a further broad based control approaches, a cross-sectional study was conducted and results compared with retrospective data. Our findings indicate that of the 290 persons enrolled based on presumptive diagnosis, 108 (37%) were positive whereas 182 (63%) negative. Age distributions of those enrolled indicates 128(44.5 %%) were above 31 years, while the least was below 5years 6(2.10%). Coincidentally, diagnosis of malaria corroborates with the age distribution of 52(48.5%) for above 31years and 1(0.01%) for below 5years, although no significant differences recorded at P>0.05. Based on gender, more males 55(38%) than females 53(37%) were positive for malaria. Malaria parasitaemia indicates most malaria positive patients had 57(52.78%) below <1000 μL-, 33 (30.56%) between 1000-5000 μL-, and 18(6.67%) above >5000 μL-. Malaria incidence rate between years 2015-2018 indicates that of the 23,745 positive patients, more males 11,880 (50.03%) than females 11,865 (49.97%) were positive to malaria, although no significant differences at P>0.05. The year 2018 recorded the highest incidence of malaria an indication that despite several efforts aimed at control and elimination, the disease still continues to persist. We therefore suggest that a multi-dimensional strategy to the control and elimination of the parasites and vectors be put in motion to help curb the menace of this disease.
Aggressive driving: self-reported anger expression and its relationship with driver personality

Aggressive driving is a global road safety concern. However, little research has been conducted to understand the frequency of aggression nor what factors contribute to this. Moreover, in these researches, the effect of personality aspects on various driving anger expressions has not been investigated. The current study aims to investigate how drivers express their anger aggressively and its relationship with The Big Five personality traits. A total of 534 licensed drivers; 36.1 % had been involved in at least one crash in the last three years completed a brief survey assessing aggression and personality. Specifically, the driving anger expression inventory, which measures the frequency of verbal aggression, personal physical aggression, aggressive use of the vehicle and adaptive constructive responses, was investigated. The most common type of aggression was verbal aggression. Younger, and male drivers reported more frequent aggression. Neuroticism was related to all types of aggression, showing individuals with more neurotic characteristics also have more frequent verbal, personal physical aggression, use the vehicle more often to express anger and have less frequent adaptive constructive ways of dealing with anger. Neuroticism was also related to more crash involvement. In contrast, drivers with higher levels of conscientiousness more frequently dealt with anger in a constructive way and had been involved in fewer crashes. These findings show that the behavior and performance of drivers can be related to their personality and individuals higher in neuroticism report more dangerous behavior. This is important to assist with strategies to reduce high-risk driving in individuals.
Business Model Themes and Product Market Strategies as Value Drivers in Omni-Channel Retail: A Set of Propositions

We focus on the analysis of current research in Business Models in the context of e-business, resulting in relevant research gaps and a set of propositions. A bibliographic review has been conducted from which a theoretical framework has been developed. Once the gaps in the literature have been pointed out, a series of research proposals are presented. These should be tested based on data collected from real cases through analysis and interpretation. The applied lens of the theory is Amit and Zotts Business Model framework (2001) and Business Model Themes (BMT) “NICE” (novelty, lock-in, complementarity and efficiency) (2001). Analysis evolves around the explanation and feasibility of Business Model Themes for value creation and value capture in digital business models (current general research gap in the e-business domain). The results show that future directions should investigate different combinations of BMTs which represent research gaps (propositions 1 to 3). Other contexts which were not considered so far in this regard (non-digital business), also represent a research gap (proposition 4). Moreover, further synthesis of the literature resulted in a potential consideration of “product market strategies” (Amit and Zott, 2008) as a new theory to apply and test value creation and capturing in digital business (proposition 5 and 6), also from an evolutionary perspective. We ask how this combination affects the performance of firms who want to move on digital transformation with an omnichannel environment. It is essential in this study how these firms can create new value and how they can keep it. We try to explain how these value drivers could be work across time, even under varying environmental regimes. It would mean an advance in the existing academic framework around the reference literature on the business model. To be able to determine which combinations of BMT and Product Market Strategy (PMS) have not yet been tested would be advantageous for the firms. It could offer the appropriate information to the retail company with traditional BM towards digital BM. Moreover, it will be able to work successfully and to maintain constant along the time.
Potential Effect of Broccoli to Reduce the Side Effects of Cisplatin Chemotherapy in Adult Rats

Multidrug resistance and various adverse side effects have long been major problems in cancer chemotherapy. The discovery of bioactive components in foods is exciting, suggesting the possibility of improved public health through diet. Broccoli floret are an excellent source of health-promoting phytochemicals such as vitamins, glucosinolates, and phenolics. The present study aimed to examine the therapeutic effects broccoli powder to reduce the side effects of cisplatin chemotherapy in adult rats. Twenty four adult male albino rats were randomly divided into two main groups; the first main group served as a negative control and the second main group (18 rats( were injected with a single intraperitoneal dose of cisplatin (CP) (10 mg/kg of B.W.). This group were divided into three subgroups, subgroup 1 served as positive control group, subgroup 2 and 3 were fed on the diet containing 2.5% and 5% broccoli powder. After completing the treatment period, animals were sacrificed under diethyl ether anesthesia. Blood samples were collected for the biochemical analysis. Results showed that group rats fed on 5% broccoli floret recorded the highest effective to reduce SGPT, SGOT, ALP, T.P, TC and TG level compared with group rats fed on 2.5% broccoli floret. Also, 5% broccoli improvement all tested oxidative enzyme (SOD, NAD and CAT) was observed. In conclusion, group rats fed on 5% broccoli floret markedly the side effects of cancer patients treated with cisplatin.
Relevance of fodder interventions on dairy farms performance in Kenya; A review

The dairy sector is the largest agricultural sub-sector in Kenya, and its share in GDP is approximately 4%. Milk consumption per head of population is one of the highest in Sub-Sahara Africa and stands at 115 litres per person. An estimated 80% of total production comes from smallholder farmers of which about 50% is marketed. Out of this 50%, 25% enters the market as processed milk and value-added milk products. The fodder interventions implemented during Kenya market-led dairy program (KMDP) inception phase confirmed that one of the most important bottlenecks for enhanced competitiveness and growth in dairy sector, is access and availability of quality fodder. This has been achieved through introduction of fodder related intervention which positively influenced milk yield, economic, and reproduction performance of the dairy farms in Kenya. The dairy sector is in agreement that without proper feed and feed rations feeding regimes the genetic potential of the breed remains unlocked, and that good fertility management relies heavily on the animal’s health and feeding. The fodder gap in dairy subsector has severe impact on cost price of milk, profitability of the farm enterprise and seasonality in milk supply. Improving fodder conservation and utilisation efficiency through high quality forages and alternative feeding practices has shown the potential to increase farmers’ income through improved milk yield and nitrogen use efficiency.
Optimising energy storage for domestic household with PV to support the grid

In this paper, load profile modelling is introduced as the basis of the research, and a practical photovoltaic (PV) profile for a typical UK household with 4kW solar system is presented to couple with the load. An evaluation on the combined profile throughout a year is done to size the required battery, and a smart domestic energy storage system is developed to integrate the domestic energy storage facility with the renewable energy generation system, in order to create a win-win situation for customers and grid. By using PV as an alternative energy resource to power the home appliances, the system can reduce the dependence of household on grid, it can reduce the stress on the grid by managing the loads and exporting excess energy back to grid to balance peak demand. Also it can cut the electricity bill for customers and make profit by selling electricity to grid. Moreover, the electricity tariff is considered in this study for system validation. The payback period of the system is evaluated against different sizes of PV-battery
Factors affecting guardians’ decision making on clinic-based purchase of children’s spectacles in Nigeria

Background: This study aims to understand the key factors influencing guardians' decisions when purchasing spectacles for their children in semi-urban and urban areas of Cross River State, Nigeria, where a spectacle cross-subsidisation scheme will be implemented. Methods: This cross-sectional study was conducted among all consecutive guardians visiting the Calabar (urban), Ugep, Ikom and Ogoja (semi-urban) public eye clinics in Cross River State, southern Nigeria, from August 1 to October 31 2019, and whose children had significant refractive errors (myopia [≤]-0.50D, hyperopia [≥]1.50D, astigmatism >0.75D) and received spectacles. Guardians were interviewed using a questionnaire which included i) close-ended questions on reasons guardians choose to purchase spectacles for their children in eye clinics, ii) guardians' perceptions of the quality and design of children's current spectacle, iii) factors most heavily influencing their choice of spectacles for children, and iv) open-ended questions to seek guardians' suggestions on how to improve the current spectacle range. Results: All 137 eligible guardians (n=92, 67.2% women) who visited the selected eye clinics participated in the study (response rate=100%), with 109 (79.6%) from semi-urban and 28 (20.4%) attending urban clinics. Guardians from both urban and semi-urban clinics prioritised frame design, quality, and material as the main factors affecting their decision when purchasing spectacles for their children. Female guardians and those with higher incomes were both 1.5 times more likely to emphasise frame quality when describing selection criteria for purchasing spectacles for their children than male guardians (p=0.01) or guardians earning less (p=0.03). Conclusion: Design, material, and frame quality are key factors influencing guardians when purchasing spectacles for their children in these setting and female guardians or those with higher income prioritise frame quality. This study could guide the planning and implementation of a novel cross-subsidisation scheme in Cross River State.
Multiplex Fragment Analysis Identifies SARS-CoV-2 Variants

The rapid spread of SARS-CoV-2 variants are of critical concern, necessitating systematic efforts for epidemiological surveillance. The current method for identifying variants is viral genome sequencing. Sequencing has multiple limitations to broad clinical adoption including requirements for technical expertise, expense of equipment and bioinformatics, and time for implementation. Here we describe a scalable non-sequencing-based capillary electrophoresis assay to affordably screen variants of SARS-CoV-2. The assay has targets for N1 (CDC nucleocapsid target, internal control), spike gene 69_70 deletion, spike gene 144 deletion, and ORF1A 3675_3677 deletion, which are all present in the B.1. 1.7 (UK) variant. ORF1A deletions alone are also present in the New York, Brazil, and South African variants. 648 specimens have been tested to date and the assay is able to detect the B.1. 1.7 variant 32 times (n=23 specimens, n=9 positive control replicates). Additionally, the B.1. 429 (California) variant can be detected when a 3bp insertion or drop out of the S144 target is present. 7/23 B.1. 1.7 specimens have been confirmed by Whole Genome Sequencing (16 pending confirmation), and demonstrate the ability to rapidly track the progression of COVID-19 variants in the population.
