In this paper, we investigate the existence of solutions for nabla Caputo Left fractional boundary value problems with a

Heat transfer coefficients of dryers are useful tools for correlation formulation and performance evaluation of process design of dryers as well as derivation of analytical model for predicting drying rates. A model equation for predicting heat transfer coefficient of air in a batch dryer using Buckingham Pi-theorem and dimensional analysis at various velocities has been formulated. The model was validated by drying unripe plantain chips in a batch dryer at air velocities of 0.66, 0.92 and 1.20m/s at temperatures of 42, 54.45 and 66°C, respectively. Based on the analogy of heat and mass transfer rate equations for constant drying period, the prediction from the developed model reasonably agreed with the experimental data

The article discusses the changes taking place in the method of financing Polish enterprises and the analysis of economic entities in the financial services sector. Concepts related to this topic were presented and forecasts for the development of the financial services market in Poland were included. Factors influencing the development of credit and factoring enterprises were indicated. The two types of financing methods for enterprises were compared and their advantages and disadvantages as well as opportunities and threats appearing in the economic environment were shown. The article also presents reflections on the direction of the ongoing economic changes.

Being the main channel to establish and develop trade relations, international business negotiations play a significant role in company businesses and foreign trade environment. On the basis of the interpersonal grammatical metaphor theory, the paper gives an analysis of interpersonal meaning in business English negotiations through examples. It illustrates the metaphorical expressions of mood and modality in business English negotiations and explores the textual function of interpersonal grammatical metaphor in business English negotiation with the purpose to observe and study how interpersonal grammatical metaphor help establish and coordinate interpersonal relationship with the allocation of grammatical resources in order to help negotiators achieve communicative purposes

Polyvinyl alcohol (PVA)/hydroxyapatite (HAp) composite fiber is obtained using hydroxyapatite made from limestone. Fiber making is done by electrospinning technique using PVA solution with each HAp concentration of 1% and 5%. The polarization images microscope shows that the average diameter of the composite fiber PVA / HAp varies depending on the concentration of HAp in the solution and the voltage applied to electrospinning. At 1% HAp concentration with a voltage of 15kV, the average fiber size was 9.83 µm and with a voltage of 17kV, the average size of the fiber was 14.46 µm. Whereas at a voltage of 20 kV, fiber yield cannot be observed. At the 5% HAp concentration with 5kV the average fiber size was 10.45 µm, with a voltage of 15 kV, the average fiber size was 10.84 µm and with a voltage of 20 kV, the average fiber size was 11.9 µm. It can be concluded that the concentration of HAp and the magnitude of the voltage affect the size of the fiber produced. For this reason, it needs to be investigated further to obtain optimal conditions.

The provision of water and sanitation globally, is threatened by climate change and pollution. Many industrialized and developing countries alike are struggling to achieve universal safe water coverage of 100% piped water connection to households and adequate sanitation. Water scarcity has imposed burden on women in their daily lives. Inadequate sanitation and outbreaks of infections have affected the health of the general population in Africa, Kenya in particular. Further to the above background, this study endeavored to establish the overall influence of determinants of implementation of water and sanitation programme in Maseno Division of Kisumu West Sub-county. Anchored on the role’s theory, the target population for the study was 31600 households. From this, a sample size of 380 respondents plus one water company manager and two field officers was drawn for Maseno division under study. Data was collected through questionnaire forms administered by research assistants. Pilot testing of the study was administered at Manyatta slums in Kisumu Central Sub-county. To uphold the content validity, the contents of qualitative data was discussed with the supervisors before conclusions and generalizations were made. Reliability was tested by Kunder-Richardson(K-R)20 formula based on the split half reliabilities of data from all possible halves of instruments. Quantitative approaches using statistical package namely frequencies, means and percentages were analyzed and presented in tables.

Institutions of higher education face a higher level of information security incidence and compromise such as data and information theft, malicious program infection, attack on the information systems infrastructure and computer network. The antagonistic impact of information security incidence includes compromise of confidential data and intellectual property, massive financial losses and increased level of information security vulnerability and threat. This study aims to determine the predictors of students’ adherence to safe information security behavior in institutions of higher education. In this study, we integrate variables from the Protection motivation theory (PMT) and the Unified theory of acceptance and use of technology (UTAUT) theory in other to understand the willingness of students to practice safe information security behavior. This study utilized the quantitative research method for data gathering and analysis. A total of 276 responses were gotten from the respondents
