Opis:
This study investigated the awareness of and demand for private agricultural extension services among smallscale farmers in Nigeria, using farmers in Oyo state as a case study. Specifically, the study examined the availability and operations of private agricultural extension services and factors that determine farmers’ willingness to pay for such services. The results showed that a considerable number of farmers are willing to pay for private agricultural extension services. The number of plots cultivated by the farmers was found to influence farmers’ willingness to pay for private agricultural extension services at one percent level of significance. Income, awareness, family size and total number of plots were identified as the major factors influencing the use of private agricultural extension services in the study area. The study recommended the need for the government to mobilize farm households to avail themselves of benefits of private extension services. Efforts should also be stepped up by all development stake-holders to provide additional sources of income for farm households, in order to raise their income and demand capabilities.
W niniejszym artykule przedstawiono badanie poziomu świadomości dotyczącej prywatnych usług w dziedzinie doradztwa rolniczego oraz popytu na nie wśród właścicieli małych gospodarstw rolnych w Nigerii. Badaną grupę stanowili rolnicy zamieszkujący stan Oyo. Szczególnie skupiono się na dostępności i funkcjonowaniu prywatnych usług w dziedzinie doradztwa rolniczego oraz na czynnikach, które wpływają na skłonność rolników do zapłaty za tego typu usługi. Wykazano, że znaczna liczba rolników jest skłonna zapłacić za prywatne usługi z zakresu doradztwa rolniczego. Okazało się, że na skłonność rolników do zapłaty wpływała liczba uprawianych działek ziemi, przy istotności na poziomie 1%. Dochód, poziom świadomości, wielkość rodziny i całkowitą liczbę działek uznano za główne ograniczenia w korzystaniu z prywatnych usług w dziedzinie doradztwa rolniczego na badanym obszarze. W artykule wskazano na konieczność zachęcenia gospodarstw rolnych przez rząd do skorzystania z prywatnych usług w dziedzinie doradztwa rolniczego. Także udziałowcy powinni podjąć kroki w celu zapewnienia dodatkowych źródeł utrzymania gospodarstwom, by zwiększyć ich dochód oraz popyt na usługi.

Opis:
Considering the phenomenal growth of network systems, congestion remains a threat to the quality of the service provided in such systems; hence, research on congestion control is still relevant. The Internet research community regards active queue management (AQM) as an effective approach for addressing congestion in network systems. Most of the existing AQM schemes possess static drop patterns and lack a self-adaptation mechanism; as such they do not work well for networks where the traffic load fluctuates. This paper proposes a self-adaptive random early detection (SARED) scheme that smartly adapts its drop pattern based on a current network’s traffic load in order to maintain improved and stable performance. Under light- to moderate-load conditions, SARED operates in nonlinear modes in order to maximize utilization and throughput, while it switches to a linear mode in order to avoid forced drops and congestion under high-load conditions. Our conducted experiments revealed that SARED provides optimal performance regardless of the condition of the traffic load.

Opis:
Tuberculosis (TB), a serious public health infection that mainly affects the lungs, is caused by bacteria (Mycobacterium tuberculosis, TB). This research is designed and analyzed using a compartmental modelling approach to study the transmission dynamics of TB with different stages of infection. Qualitative analysis of the proposed model reveals that the model exhibits two equilibrium points: the disease-free equilibrium point (DFE) and the endemic equilibrium (EE). The basic reproduction number (R0 ) is determined using the next generation matrix technique, and stability analysis is carried out to show whether the disease can persist or die out in population. Further analysis of the model shows that the EE is globally asymptotically stable (GAS) when R0 > 1. With the aid of the forward sensitivity index method, we determine the most sensitive parameters of the model to control the spread of TB infection effectively. Our analysis shows that treatment (medication) and campaign awareness coupled with other key control measures, could help maintain the spread of MTB infection in human geographical boundaries.

Opis:
One of the challenges facing wildlife conservation is how to change the way people perceive wildlife. Therefore this study examine wildlife conservation awareness and practices in some selected secondary school around Kainji Lake National Park. Data was collected through the use of pre tested structured questionnaires among six selected secondary school in the study area. The sample of the research was one hundred (100) respondents. Data was analysis using descriptive statistics. The findings reveals that majority of the respondents (74%) are male and age group 15-20 years had the highest with 43%. 63% of the respondents are aware of wildlife conservation in the study area and majority (66%) of the respondent has not visit the Kainji Lake National Park. 50% of the respondents had about wildlife through direct communication. 63% and 80% of the respondents are willing and are ready to support wildlife conservation in the study area. The finding still reveal that awareness is still lacking in most schools among the communities. Therefore more wildlife conservation awareness is needed in our various schools so as to get the interest of the students when they are still young so that generation coming will also be thought.

Opis:
Dam construction is one of the measures that is inevitable in many cases and must be done to supply drinking water, agricultural uses and electricity generation. There are many challenges to a successful dam project, and the managers of each project must consider the appropriate solutions for them. One of the studies that is done in dam design is sedimentation in dam reservoirs. The experimental area-reduction method is a very common technique that obtains the sediment distribution in depth and longitudinal profile. This technique shows that sediment accumulation is not limited to the bottom reservoirs. Sediment accumulation in a reservoir is usually distributed below the top of the protection reservoir or normal water level. In this study, the distribution of sediment in the reservoir of Karun Dam after a period of 65 years has been done using the experimental area-reduction method. Elevation-volume and elevation-area curves of the dam reservoir are obtained after the useful life of the dam and sediment deposition. The results showed that after 65 years, 106.47·106 m3 of sediment is deposited in the reservoir of the dam and the useful volume of the reservoir is significantly reduced. Also, up to a height of 36.4 m, the dam reservoir is filled with sediment. Therefore, no valve should be placed up to this height.
