Perspectives of Blockchain in Cybersecurity
Authors: Obaidat Muath A. , Brown Joseph
Published: March 2021

In recent years, blockchain has emerged as a popular data structure for use in software solutions. However, its meteoric rise has not been without criticism. Blockchain has been the subject of intense discussion in the field of cybersecurity because of its structural characteristics, mainly the permanency and decentralization. However, the blockchain technology in this field has also received intense scrutiny and caused to raise questions, such as, Is the application of blockchain in the field simply a localized trend or a bait for investors, both without a hope for permanent game-changing solutions? and Is blockchain an architecture that will lead to lasting disruptions in cybersecurity? This chapter aims to provide a neutral overview of why blockchain has risen as a popular pivot in cybersecurity, its current applications in this field, and an evaluation of what the future holds for this technology given both its limitations and advantages.

The Lycian Nappes contain slices of ophiolites and sedimentary rocks of various ages that crop out in SW Turkey. They evolved and were emplaced under the effect of the Late Cretaceous-Miocene compressional regime. The Tavas Nappe is part of the Lycian Nappes and contains Jurassic-Eocene sediments. The Babadağ Formation, forming the middle part of the Tavas Nappe, is composed of limestone at the base and various sized calciturbidites with chert intercalations in the upper part. The Standard Microfacies Classification (SMF of FLÜGEL, 2004) indicates that the entire unit was deposited mainly in a deep-shelf environment (Facies Zone – FZ-2), deep-sea (FZ-1), toe of slope (FZ-3) and on the continental slope (FZ-4). Calcite and quartz dominate the bulk mineralogy of the calciturbidites with higher SiO2 and CaO weight percentages than other major oxides. Additionally, the presence of Na2O, K2O, Al2O3, MgO, TiO2 and Fe2O3 is associated with the local sediment input. Tectonism and sea level fluctuations were the main triggering factors of the changes in the original depositional environment of the Babadağ Formation. Additionally, grain size and the amount of sediment input control the calciturbidite type and extension. Si enriched water circulation and Si and Ca substitution were responsible for the abundant chert formation during diagenesis of the units. Post depositional tectonic activities during transportation and emplacement of the nappes resulted in calcite filled cracks that cut both the calciturbidites and cherts. Study of the different nappe slices provides valuable information about syn- and post- depositional changes of the lithostratigraphic units.
The clinical course and diagnostic relevance of olfactory loss in a SARS-CoV-2 infection
Authors: Bauwens M.J. , Claeys S.
Published: March 2021

Background: The acute onset of olfactory and/or gustatory dysfunction is a frequent complaint during the COVID-19 pandemic. It is predominantly reported by subjects with asymptomatic to mild disease severity during the early stage of the infection. The high prevalence of anosmia/dysosmia and/or ageusia/dysgeusia in this current era implements a strong correlation with a SARSCoV-2 infection and these symptoms could therefore be seen as important prodromes. The purpose of this study was to outline the occurrence, epidemiology and clinical course of olfactory and/or gustatory disorders in (suspected) COVID-19 cases and to analyse the diagnostic significance of these neurosensory dysfunctions. Methods: An online questionnaire was carried out which addressed 500 participants with new onset olfactory and/or gustatory impairment during the COVID-19 pandemic. Results: Acute olfactory and gustatory loss was reported by 487 (97.4%) and 464 (92.8%), respectively. A significant higher prevalence of neurosensory complaints was reported by women and people of younger age. The most prevalent concurrent symptoms were fatigue, headaches, nasal congestion, dry cough, rhinorrhoea and sneezing. The recovery rate after 8 weeks was 41.9% for olfactory impairment and 53.7% for gustatory impairment. Among the 93 subjects tested, 82 (88.2%) tested positive for SARSCoV-2. Conclusion: Olfactory and/or gustatory disorders are prevalent clinical findings during the COVID-19 pandemic. Neurosensory impairments, isolated or in association with other mild complaints, need to be addressed as potential symptoms of a SARS-CoV-2 infection and should be implemented as clinical markers.

In Mali, climate change is a major threat to the productivity of food security crops such as sorghum (Sorghum bicolor (L.) Moench, 1794). The objective of this study was to analyse farmers’ perceptions of climate change effects, on sorghum productivity and the adaptation related strategies. A total of 352 sorghum farmers in the Sudanian and Sahelian zones of Mali were interviewed, using a semi-structured questionnaire. Data collected were related mainly to the farmers’ socio-economic profiles, indicators used to characterise climate change and strategies developed to cope with it. Irregular rainfall, marked rise in temperatures and early cessation of the rainy seasons were the main manifestations of climate change effects according to the respondents. These effects reportedly resulted in a drastic drop in sorghum yields. Use of meteorological information (19.89% of the respondents), use of early and drought-resistant varieties (13.35% of the respondents), and intercropping of sorghum with other crops (25.85% of the respondents) were the strategy options adapted by farmers. The choice of an adaptation strategies was largely dependent on the number of years of experience in sorghum production, and the number of labour providers available in the household. It is imperative to assess and refine the agronomic effectiveness of these coping strategies to improve sorghum productivity in the study areas.

From "Clueless" to "Completed": A Review of The Essential Guide to Doing Your Research Project
Authors: Yehl Angela
Published: March 2021

O'Leary (2010) has written her book for the student; however, she delves beyond the "how to" of most introductory research texts. The author works to ground students in the theoretical and foundational aspects of qualitative, quantitative, and mixed methods research, in addition to providing "real world" advice and common scenarios often encountered in the field. From determining an appropriate sample size to navigating political processes in evaluative research, O'Leary stays grounded in the practical, often re-emphasizing the importance of "doability" in planning and conducting any type of research.

Islam in a Secular State
Authors: Abdullah Walid Jumblatt
Published: March 2021

The overtly secular state of Singapore has unapologetically maintained an interventionist approach to governance in the realm of religion. Islam is particularly managed by the state. Muslim activists thus have to meticulously navigate these realities – in addition to being a minority community – in order to maximize their influence in the political system. Significantly, Muslim activists are not a monolith: there exists a multitude of political and theological differences amongst them. Islam in a Secular State: Muslim Activism in Singapore analyses the following categories of Muslim activists: Islamic religious scholars (ulama), liberal Muslims, and the more conservative-minded individuals. Due to constricting political realities, many activists attempt to align themselves with the state, and call upon the state to be an arbiter in their disagreements with other factions. Though there are activists who challenge the state, these are by far in the minority, and are typically unable to assert their influence in a sustained manner. The author draws upon his own experiences as a researcher and as someone who was involved in some of the discourses explored in this book.

Published: March 2021

En els darrers anys, l’ús intensiu de les tecnologies a l’escola, ha provocat que el professor de vegades es senti desbordat quan ha d’atendre la gestió de l’aula i no tan sols els  aspectes d’ensenyament i aprenentatge curriculars sinó també altres, pels que sovint no està preparat, com són els relacionats amb la competència digital i la resolució de les incidències tècniques que es produeixen amb qualsevol dels dispositius de l’aula. És per això, que a l’escola Jesuïtes Bellvitge s’ha decidit separar els aspectes pedagògics i didàctics dels tècnics per tal de concentrar els esforços en la finalitat última del procés d’ensenyament i aprenentatge. El lideratge pedagògic de la classe el porta el professor però és un grup d’alumnes “experts TIC” el que a cada classe porta el lideratge tecnològic i fan de suport al professor de l’aula i als seus companys. En aquest article es pretén descriure i avaluar l’experiència dels experts TIC de l’escola Jesuïtes Bellvitge segons els seus protagonistes arribant a la conclusió que aquesta experiència, ha fet que l’ús de les TIC a l’aula es pugui estendre homogèniament en els diferents cursos amb independència de la competència digital docent del professor.

Connected in the street: the relation between online social networks, self-esteem and satisfaction with life among individuals experiencing homelessness
Authors: Calvo Fran , Carbonell Xavier , Turró Oriol , Giralt Cristina
Published: March 2021

The universalisation of Social Networking Sites has prompted a debate about whether contact with relatives and friends online has a positive effect on psychological well-being, as it has on direct relationships with primary groups. The aim of this study is to analyze the use of social network sites in a sample of 164 individuals experiencing homelessness (IEH), and to establish the relationship between this usage and their levels of self-esteem and satisfaction with life, using a multiple linear regression model for each dependent variable. The main results show a high prevalence of Internet and social network sites usage amongst IEH, even slightly higher than in the population overall.The variables predicting a higher degree of well-being are related to the use of social network sites, especially keeping in touch with friends. The chronicity associated with length of time on the street is also a key factor. A debate exists regarding the benefits of social network sites on health, and the importance which education may have in improving access to specialized services.
Uso lúdico de las TIC, procrastinación y género: un estudio con alumnos de educación primaria/ Leisure use of ICT, procrastination and gender: a study of primary school students
Authors: Badia Martín Mar , Dezcallar Teresa , Cladellas Pros Ramon
Published: March 2021

En este trabajo se estudia la relación entre el uso lúdico de la televisión y los videojuegos en alumnos de primaria y su tendencia a la procrastinación.Se recabó información de los padres de 670 alumnos. Los resultados mostraron que en los alumnos los cambios en la procrastinación en función del tiempo de televisión son más radicales que en las alumnas. En cuanto a los videojuegos, las niñas con un tiempo de videojuegos considerado “poco” o “normal” (menos de 330 minutos a la semana), son las que procrastinan menos. La variable género desempeña un papel interesante en la procrastinación.This paper studies the relationship between primary education students’ leisure use of television and video games and the students’ tendency to procrastinate. Information was gathered from the parents of 670 students. The results showed that male students experienced greater changes in procrastination as a function of television time than female students. In terms of video games, girls who spend “little” time or a “regular” amount of time (less than 330 minutes a week) playing video games are the least likely to procrastinate. The variable of gender plays an interesting role in procrastination.
A comparative analysis of the processing speed between video game players and non-players
Authors: Pardina Torner Helena , Carbonell Xavier , Castejón Marcos
Published: March 2021

Speed is an essential cognitive skill in our day to day life, as such, it has been extensively studied. The uncertainty of whether the processing speed can be increased with appropriate training-within one individual, across a range of tasks, and without compromising accuracy- remains to this day. The aim of the present study was to analyse the processing speed of video game players and compare it to non-video game players to see if there are any significant differences between these two groups. To this end, a questionnaire on gaming habits and sociodemographic data, and two tests that evaluate the processing speed were administered to a sample of 50 university students from different degrees. The scores were then compared and, taking into account the possible errors, results showed that video game players have a shorter reaction time than non-video game players and that neither of the groups made more mistakes than the other.
Shades of Foods: Prevalence and correlates of food addiction
Authors: Wang Chung-Hui , Lopez-Fernandez Olatz
Published: March 2021

Background: Growing evidence suggests that certain foods have addictive properties. Food addiction has sparked interest within the scientific community. The purpose of this study was to estimate the prevalence of food addiction to examine their differential characteristics, and the association between food addiction symptoms and physical and psychological variables, such as eating-related behaviours, body mass index (BMI), and personality traits (e.g., types of narcissism).Method: The sample consisted of 208 participants (mean age = 26.82 ± 7.89 years; BMI = 27.53 ± 12.21 kg/m2; 80.3% female; 79.3% White). Participants completed a web-based self-report survey of food addiction containing the questionnaires to measure these constructs. The main scale used as an outcome variable was the Yale Food Addiction Scale (YFAS).Results: 14.4% of participants met the YFAS diagnostic criteria for potential food addiction. Individuals who met the criteria displayed greater food craving, more frequent consumption of sugary foods, the tendency to develop eating disorders, and more negative attitudes toward and thoughts of physical appearance. Those categorised as food addicts also exhibited a lower level of self-esteem and grandiose narcissism, and a high level of hypersensitive narcissism. Food craving and body image issues were associated with the severity of food addiction.Conclusions: The findings of this investigation supported the construct of food addiction as both, addictive behaviour and behavioural addiction. Furthermore, it was suggested that this potential addiction is related to overweight and obese individual young females.

Authors: Otero-Saborido Fernando Manuel , Palomino-Devia Constanza , Bernal-García Ainara , Gálvez-González Javier
Published: March 2021

El Sistema de Europeo de Transferencia y Acumulación de Créditos (ECTS) estima la carga de trabajo del estudiante tanto presencial como no presencial en los países de la Unión Europea. El objetivo de este estudio fue cuantificar la carga de trabajo en el uso de flipped learning y la evaluación formativa a partir de la estimación semanal del alumnado universitario. Para ello se diseñó un estudio longitudinal durante un semestre en el que participaron 75 alumnos (19.8 ±3.48 años) del primer curso del grado de Ciencias de la Actividad Física y del Deporte. A través de un instrumento validado, el alumnado fue estimando semanalmente su volumen de trabajo. Los resultados muestran que el alumnado dedica un promedio semanal de 2.20 ±0.75 horas no presenciales. La diferencia entre lo estimado por el alumnado y el ECTS fue negativa (–62.30%; p <0.000) respecto a la métrica europea. Las actividades no presenciales a las que el alumnado dedicaba mayor tiempo fueron la preparación de la clase práctica (43.4 ±25.5 minutos) y la lectura de textos (30.7 ±12.5 minutos) previa a la sesión presencial. Se concluye que, si bien ECTS sirve como moneda de movilidad europea, la carga de trabajo ECTS está sobrestimada incluso en el uso de metodologías activas, y no es realista ni sostenible para el alumnado.
VALUATING THE POTENTIAL OF TRIDAX PROCUMBENS FOR LIVESTOCK FEED
Authors: Kalu B. A. , Njike M.G. , Ikurior S.A.
Published: March 2021

A quantitative method of specifying the morphological stage of development in Tridax procumbens was used for evaluating the chemi­cal composition of the plant at specified cano­py ages. An eight stage classification system was defined and assigned numerical values from 1 to 8 in a sequential order of increasing maturity. The mean stage of total herbage (MSW) at a specified age of canopy was calcu­lated as the average of the individual stages present and weighted for the dry weight in each stage. For the individual morphological stages present in a herbage samples, quality components measured by. leaf percentage, crude protein (CP), in vitro true digestibility (IVTD), progressively decreased with maturi­ty. From the vegetative to the mature seed stage, decreases were from 90% to 26% for the leaf proportion; 28% to 14% for CP; and from 82% to 53% for IVTD. Corresponding increases in fibre composition were from 26% to 59% for the total cell wall or neutral deter­gent fibre (NDF); 22% to 40% for ligno-cellu­lose or acid detergent fibre (ADF); and from 25% to 9% ilignin. . Older canopies reached siginificantly higher mean stage (MSW) values than younger canopies. Associated with these were lower percentage, CP, and IVTD; higher NDF; ADF, and lignin at higher MSW values. The implications of these findings are fully discussed

TO date, there is little or no information on fungal diseases of animals in Nigeria. This paper presents eight cases of deep-seated mycoses of livestock observed in Ibadan. They include two cases of phycomycosis and four of aspergillosis affecting cattle and sheep, and two cases of nocardiosis affecting cattle. The phycomycosis involved the alimentary tract and adjacent abdominal organs as well as the eye. The aspergillosis affected the respiratory system and the rumen and abomasum. Bovine nocardiosis affected lymph nodes, skin and mammary gland. As the infective organisms live in the soil and mouldy feeds, improved sanitation in the farm can help to reduce the incidence of these diseases which generally respond poorly to treatment.

Published: March 2021

Bacterial diseases caused deaths in 84.68 percent of dead pigs recorded in piggeries of Jos Area of Plateau State of the bacterial diseases the most prevalent were colibacillosis, erysipelas, oedema disease, pneumonias and salmonellosis. But deaths in 9.68 percent were due to non-infectious causes. Ascariasis and cysticercosis were the main parasitic diseases. Early treatment of sick swine and improved husbandry and management would have certainly reduced the losses which the pig producers had sustained in consequence of these conditions

The influence of lamb birth weights, year of

birth, and parity on pre-weaning death were observed in Yankasa sheep over a period of 4 years (1989-1992) in Misau, Bauchi State, Nigeria. Of the 150 lambs observed, birth weight fell into 4 categories; upto 1.5; 1.6-2.0; 2.1-23 and 2.6 -3.0 Kg, with percentage deaths in each being 33, 34,16 and 0, respectively. The overall mean birth weight was 23±0.03, and overall percentage mortality was 18%. Significant correlation (p < 0.05, r = 0.49) was observed between birth weights and deaths incidence. Significant year and parity differences existed in lamb birth weights (P.< 0.05). 90% of the ewes lambing were in their 1st parity, while 6% and 4% respectively were in the 2nd and 3rd parities. Mean birth weights were heaviest for lambs with ewes in their 2nd parity 2.6 (0.46), followed by those in their 1st parity 23 (0.27) and those in their 3rd parity 2.2(0.27). Percentage mortality increased with parity, being 14,27 and 50 for 1st, 2nd and 3rd parities respectively. Chi-square analysis showed no significant differences between the ratio of ram to ewe lambs, though ram lambs were significantly heavier than ewe lambs. Low lamb birth weight was found to be a major cause of pre-weaning mortality in Yankasa sheep in Misau, Nigeria.

Fourteen fryer male rabbit (New Zealand white and chinchilla breeds) were used for the experiment. Equal numbers of rabbits from the two breeds were used for each treatment. The rabbits were randomly Leucaena leucocephala respectively. The rabbit in the two groups were given the same amount of pelleted concentrates from a commercial feed miller and were  fed to determine the effect of level of leucaena offered/intake on the growth rate of rabbits. Four fryers which were fed the same % of concentrates and Aspilia africana served as the control. Growth rate decreased at the beginning of the study followed by satisfactory growth thereafter. The control animals had a higher growth rate compared to the other two groups (P<0.05. Alopecia and decreased appetite were the initial symptoms of mimosine toxicity observed, but they were soon overcome with time. Rabbits can tolerate up to 100g leucaena in their diet in addition to pelleted concentrate.
THE EFFECT OF SEASONAL VARIATION ON PERFORMANCE OF EGG TYPE POULTRY: A Case Study of Mitchell Farms, Mosogar, Delta State, Nigeria
Authors: Guobadia E. E.
Published: March 2021

The study was designed to find out the effect of seasonal variation on poultry in Delta State of Nigeria. The variables considered were mortality rate, feed intake, egg production and egg hatchability in the wet and dry seasons of the year. Secondary data were also collected from records kept in the farm. Sites 4AHI-BLK,5AKI-BLK, 9H/BF and 10H/BF were used for the study with each having an average of 2,500-3,500 birds of the same breed and sex aged 1-9 weeks and 21-52weeks. The records were grouped into dry season (October-March) and wet season (April-September) covering three years, 1991-1994. The analysis of the result showed that seasonal variation does not have any significant effect (P < 0.05) on mortality and feed intake in the two seasons. However percentage egg production and egg hatchability revealed a significant difference (P < 0.05) between the two seasons, with a mean % egg production and hatchability of 74±.03 and 80.6 in the wet season and 53.67±0.01 and 55.9 respectively in the dry season. Recommendation is therefore made for proper planning which ensures the utilization of wet and dry season management practices to reduce the effect of high humidity and embient temperature on production.
Plasma Calcium and Phosphorus In Weanling Pigs as Influenced by Dietary Calcium: Phoshporus Ratio and Cestrum Diurnum Ingestion

Published: March 2021

Twenty Yorkshire piglets weaned at approximately 4 weeks of age, were used in this study to investigate the variations in plasma calcium and phosphorus as influenced by dietary calcium and phosphorus and 3 Cestrum diurnum. In the CCD and TCD pigs, hypercalcemia developed rapidly and persisted following the feeding of 3% C. diurnum. While hypophosphatemia occurred in the CCD pigs, there was an initial and transient hyperphosphatemia with subsequent and terminal hypophosphatemia in the TCD pigs The hypercalcemia induced by the ingestion of 5% C. diurnum in the CCD and TCD pigs is attributed to increased intestinal absorption of calcium and not to bore resorption. The initial hyperphosphatemic response in TCD pigs is also believed to be due to increase absorption of phosphorus from the high phosphorus diet.

Abstract. We examined the impacts of aerosol-radiation interactions, including the effects of aerosol-photolysis interaction (API) and aerosol-radiation feedback (ARF), on surface-layer ozone (O3) concentrations during one multi-pollutant air pollution episode characterized by high O3 and PM2.5 levels from 28 July to 3 August 2014 in North China, by using the Weather Research and Forecasting with Chemistry (WRF-Chem) model embedded with an integrated process analysis scheme. Our results show that aerosol-radiation interactions decrease the daytime downward shortwave radiation at surface, 2 m temperature, 10 m wind speed, planetary boundary layer height, photolysis rates J[NO2] and J[O1D] by 115.8 W m−2, 0.56 °C, 0.12 m s−1, 129 m, 1.8 × 10−3 s−1 and 6.1 × 10−6 s−1, and increase relative humidity at 2 m and downward shortwave radiation in the atmosphere by 2.4 % and 72.8 W m−2. The weakened photolysis rates and changed meteorological conditions reduce surface-layer O3 concentrations by up to 11.4 ppb (13.5 %), with API and ARF contributing 74.6 % and 25.4 % of the O3 decrease, respectively. The combined impacts of API and ARF on surface O3 are further quantitatively characterized by the ratio of changed O3 concentration to local PM2.5 level. The ratio is calculated to be −0.14 ppb (µg m−3)−1 averaged over the multi-pollutant air pollution area in North China. Process analysis indicates that the weakened O3 chemical production makes the greatest contribution to API effect while the reduced vertical mixing is the key process for ARF effect. This study implies that future PM2.5 reductions will lead to O3 increases due to weakened aerosol-radiation interactions. Therefore, tighter controls of O3 precursors are needed to offset O3 increases caused by weakened aerosol-radiation interactions in the future.
How many grains are needed for quantifying catchment erosion from
tracer thermochronology?
Authors: Madella Andrea , Glotzbach Christoph , Ehlers Todd A.
Published: March 2021

Abstract. Detrital tracer thermochronology exploits the relationship between bedrock thermochronometric age-elevation profiles and a distribution of detrital grain-ages collected from river, glacial, or other sediment to study spatial changes in the distribution of catchment erosion. If ages increase linearly with elevation, spatially uniform erosion is expected to yield a detrital age distribution that mirrors the catchment's hypsometric curve. Alternatively, a mismatch between detrital and hypsometric distributions may indicate non-uniform erosion within a catchment. For studies seeking to identify the pattern of erosion, measured grain-age populations rarely exceed 100 grains due largely to the time and costs related to individual measurements. With sample sizes of this order, discerning between two detrital age distributions produced by different catchment erosion scenarios can be difficult at a high statistical confidence level. However, there is no established method to quantify the sample-size-dependent uncertainty inherent to detrital tracer thermochronology, and practitioners are often left wondering how many grains is enough?. Here, we investigate how sample size affects the uncertainty of detrital age distributions and how such uncertainty affects the ability to uniquely infer the erosional pattern of the upstream area. We do this using the Kolmogorov-Smirnov statistic as metric of dissimilarity among distributions, based on which the statistical confidence of detecting an erosional pattern is determined through Monte Carlo sampling. The techniques are implemented in a new tool (ESD_thermotrace) to consistently report confidence levels as a function of sample size and application-specific variables. The proposed tool is made available as a new open-source Python-based script along with test data. Testing between different hypothesized erosion scenarios with this tool provides thermochronologists with the minimum sample size (i.e. number of bedrock and detrital grain-ages) required to answer their specific scientific question, at their desired level of statistical confidence. Furthermore, in cases of unavoidably small sample size (e.g., due to poor grain quality or low sample volume), we provide a means to calculate the confidence level of interpretations made from the data.
