Construction, Operation and Maintenance of family- sized Biogas Digester

By Dr. (mrs.) E.o. Uzodinma

Nigeria is richly blessed with various sources of energy both renewable and non- renewable. However, the conventional energy resources such as petroleum, natural gas and coal exploited at commercial quantities are non-renewable and cannot sustain the economy for a long time. There has been a constant period of energy crisis which has manifested in the form of frequent shortages of energy-giving petroleum products and erratic grid electricity supply. This persistent energy problem in the country has disrupted major productive economic activities mostly in the industrial sector where effective operation of machinery and equipment is dependent on energy; artisans like welders, transport industry and households have also been adversely affected.
Climate change due to increasing concentrations of greenhouse gases , namely: carbon dioxide, methane, carbon monoxide, oxides of sulphur, chlorofloro carbons (CFCs) and some oxides of nitrogen, pose threat to human society. The chemicals act by changing the living and working environment to which society has adapted over the generations.

Open Education, Open Educational Resources (OER) and Hyperlinks

By Gaius Ebere

Education is essential to the advancement of any society. By education we pass down the wealth of
human knowledge and equip the next generation of leaders, innovators and productive members of
the society. Our educational systems are built to provide every person the opportunity to build a better
life - by turning children into citizens, learners into teachers, laborers into skilled workers.
Expanding educational opportunities is more possible now than it has ever been before. Through the
Internet, learners can find information instantly on virtually any topic, teachers can share their
knowledge with students on another continent almost as easily as in their own classroom, and
educational materials can be disseminated to a worldwide audience at virtually no marginal cost.
However, educational materials market is held captive by traditional publishing models that actively
restrict the dissemination and innovative use of resources in a world that craves educational
opportunities. Textbook prices have continued to rise rapidly, leaving too many students without
access to their required materials. Digital offerings from traditional publishers come laced with access
restrictions and expiration dates with little savings in return, and print editions are too often out of date
by the time they hit the shelves.

Quality Assurance in Open and Distance Learning (ODL)

By Gaius Ebere

The effective delivery of education has gone beyound the conventional face-to-face (f2f) mode where students must have personal contact with their lecturers. Open and Distance Learning (ODL) mode of education delivery removes the distance, age and job barrier and makes education available to those who, otherwise, would not have been able to cope. Arguments have risen as to the quality of education given out through the ODL as compared to that of the f2f delivery mode. To this effect, proponents of the ODL has deem it necessary to evolve a system of quality assurance in ODL to make sure that quality is not compromised in the delivery of education through ODL. This work aims at detailing the quality control measures necessary to be put in place to guarantee quality education delivery in the ODL mode.
