Mathematical Modelling of Forestry Biomass Conservation and Wildlife Population Dynamics| Chapter 6 | Mathematics and Computer Science: Contemporary Developments Vol. 5

Researchers have proposed various mathematical models to study forest depletion caused by resource-independent industrialization (population) by considering the spatial distribution of both forest biomass and the density of industrialization within a single homogeneous habitat. In this study, a non-linear mathematical model for the conservation of forestry biomass and wildlife population is developed and examined. The model assumes that the growth rate of wildlife conservation is directly proportional to the reduction of forestry biomass caused by the wildlife population. Additionally, in modelling process, the study investigate the impact of illegal trade on both forestry biomass and wildlife populations. The model equations are studied to understand the nature and stability of equilibrium points using the theory of nonlinear ordinary differential equations and numerical simulations. Moreover, sufficient conditions for the persistence of the system are derived through differential inequalities. The analysis reveals that the depletion of forestry biomass and wildlife populations can be mitigated through effective wildlife conservation. To achieve optimal results in wildlife conservation, it is crucial to minimize the rate of governance failure.

The Persistence of Examination Misconduct in Nigerian Higher Education Systems: The Connection with the Degradation of the Family and Education Institutions | Chapter 1 | Modern Perspectives in Language, Literature and Education Vol. 6

 The continuance of test misconduct in Nigerian higher education systems was explored in this essay, as well as the dysfunctionality of families and educational institutions. The methodology used in the study was information gathered from a secondary source and content analysis. The longevity of examination misconduct has been connected to various issues, including bad parenting, a lack of good upbringing in the home, and corruption in educational institutions, according to R. K. Merton's idea of dysfunctionality. In its final observations, the report suggested that if families and educational institutions could actively execute their sociological responsibilities, the pace at which examination dishonesty is rising in tertiary institutions might be substantially reduced.

Soil pH Interference in the Behavior of Weak Acid Herbicides | Chapter 5 | Recent Progress in Plant and Soil Research Vol. 1

 Herbicides derived from weak acids can be affected in their sorptive capacity when they interact with soil pH. As a result, when their pH rises, they can reduce their sorption in the soil and increase their leaching. This increases the herbicide's bioavailability in the soil, resulting in a greater control effect on weeds and crop injuries. However, if there is rain, the herbicide may be transported by leaching in the soil profile to the deeper layers of the active seed bank, reducing weed control. Given the foregoing, it is critical to investigate the interactions with soil pH in risk assessment and agronomic procedures. The analysis of the herbicide's behavior in the soil, as well as the correct positioning of the product in chemical management. This chapter explains how the pH of the soil can affect the behavior of weak acidic herbicides in a chemically understandable way for agrarian scientists. The difference in electric charges of ionized herbicides and colloids was critical in understanding how these interactions occur, which are influenced by soil type and pH. Finally, it is expected that professionals who work with herbicides will be able to better understand some of the interactions of herbicide chemical molecules with soil and make appropriate recommendations.

Organokinetics for Transient Cytomegalovirus Infection in Mice | Chapter 12 | Recent Research Advances in Biology Vol. 8

 The basic level of CMV diffusion into mouse organs was identified, as well as its relevance. This was conducted prior to our involvement in a larger project examining the immunological and molecular aspects of MCMV infection pathogenesis in Balb/c mice. We may have created potential to produce one or more vaccinations against the virus as a result of our endeavour. The virus was administered intraperitoneally to mice. The spleen, salivary glands, inguinal lymph nodes, liver, bone marrow, and lungs of mice were collected on days 1, 3, 7, 14, and 28 following infection. The organs were tested for MCMV-DNA expression, infectious viral titer, and morphological examination of a portion of the tissues that had been formalin-fixed and paraffin-embedded. Each organ had a unique configuration of the three components, which reflected the viral spread. Thus, substantial quantities of DNA and low titers of infectious virus were found in the lungs and bone marrow, indicating latency. High levels of MCMV-DNA and consistent titers of infective virus in the salivary glands indicated a chronic infection, as evidenced by high levels of MCMV-DNA and continuous titers of infective virus that remained beyond day 28. The most striking conclusion was that the latency detected in the spleen was most likely found in the stromal cells, not the lymphocytic component. We may have figured out the MCMV path in the mouse to this point.

PLS-SEM Based Service Quality and Satisfaction Analysis in Sri Lanka's Open Distance Learning | Chapter 6 | Insights into Economics and Management Vol. 9

 In today's Higher Education (HE) field, Students' Perceived Service Quality (SPSQ) and Students' Satisfaction (SSAT) in Open Distance Learning (ODL) are well-known qualities. On various reasons, a large number of research papers have explored various sorts of factors. The ODL students come from a variety of family backgrounds, including cultural, social, and technological skill levels, and they all lack fundamental educational admission criteria. This must take into account how HE institutions might combine their diverse offerings with quality-added features to gain a competitive advantage in terms of student satisfaction. When compared to the increase in the number of registered students year after year, the number of students finishing the course or graduating is decreasing. Most colleges and higher education institutions have struggled with student retention and attrition issues, and have rushed to develop solutions based on the notions of service quality and satisfaction. The primary goal of this research is to identify the major elements that influence the SPSQ and SSAT. The modified SERVQUAL components will be examined in relation to the SPSQ and SSAT in this study. Assurance, Empathy, Responsiveness, Reliability, and Website Content were the independent variables, while Students' Perceived Service Quality and Satisfaction in ODL in the OUSL were the dependent factors. A self-administered questionnaire was used to collect data from 760 undergraduate students at the Open University of Sri Lanka (OUSL) in six major regional centers around the island. In Sri Lanka, the OUSL is the only university that operates under the ODL system. Descriptive and inferential statistics were used in the analysis. The SPSQ and Reliability, Responsiveness, and Website Content all have important correlations. SSAT's correlations with Reliability and Website Content, as well as the relationship between SPSQ and SSAT, are also noteworthy. The SPSQ has an R2 of 0.244 (24%) and the SSAT has an R2 of 0.549. (55 percent ). The same study could be proposed as a future study with more service quality characteristics, as well as a longitudinal data collection method at regional centers to learn more about service quality and satisfaction, which influence student retention and completion. The inconsequential relationships that students have bestowed onto their teaching staff the attributes of Assurance and Empathy. The other three service qualities (responsiveness, reliability, and website content) must be taken into account and given special attention in order to improve the service quality of the offered service.

Investigating the Dissipation of Fluopyram and Tebuconazole Residues in/on Pomegranate and Soil | Chapter 9 | New Ideas Concerning Science and Technology Vol. 2

 The indiscriminate application of pesticides has contributed to the accumulation of residues of pesticides both in the main agricultural products and in the soil. The studies were conducted to establish the dissipation pattern of two fungicides by following Good Agricultural Practices (GAP) Fluopyram, a succinate dehydrogenase inhibitor (SDHI) and tebuconazole, demethylation inhibitor (DMI) were used for the management of powdery mildew and anthracnose diseases in grape and results indicated that fluopyram dissipated with a half life of 4.04 and 5.18 days, at The half life values observed for tebuconazole were 4.75 and 5.42 days, respectively. Residues reached below the 10th and 15th day quantification limit (BQL) in both fungicides at the prescribed and twice the recommended dose, respectively, suggesting a 10-day pre-harvest period (PHI) for fluopyram and tebuconazole may be considered when 75g a.i./ha and 150g a.i./ha respectively are added.

A Study on the Caucasus Region: Crop Model Based on “Slow” Climate Change over the Last 60 Years | Chapter 1 | Modern Advances in Geography, Environment and Earth Sciences Vol. 1

 

The analysis is based on instrumental data (temperature and rainfall) from 20 weather stations located between 1961 and 2018 on the territory of the Caucasian region. Mathematical statistics approaches, trend analysis and the rescaled range approach have been used. The warming trend was found to have occurred in all climate zones, accelerated since the beginning of global warming (since 1976), although precipitation shifts were not so unidirectional. Maximum warming (average of 0.38 ° C/10 years) in all climate zones was observed in the summer. The Hurst exponent H (range of variance from 0 to 1) was used to examine persistence patterns, which showed a higher trend in persistence of annual mean temperature changes (H = 0.8) relative to annual sum precipitation (H = 0.8) To = 0.64). The precipitation and temperature spatial correlation analysis showed a rapid decrease in the correlation of precipitation at different weather stations from rp = 1 to rp = 0.5 on a distance scale from 0 to 200 km. A multiplicative model of agrometeorological resources was proposed to take into account the "slow" climate changes, during the construction of which it was presumed that they were determined by seasonal values of average air temperature and precipitation. Two models of agro-climatic tools are proposed, provided the seasonal characteristics of crop cultivation (winter wheat, spring wheat).
