WASTEWATER TREATMENT PROCESS AND TECHNOLOGY

Wastewater treatment plant prevent potential waterborne disease outbreak. This is achieved by the active use of mechanical process and biological process of the treatment plant to treat and convert wastewater into clear effluent that meets specific standard. The effluent water can be used for irrigation and domestic purposes, and the thickened sludge as organic manure for farming. Monitoring of the wastewater process, beginning from the up-stream through the down-stream, to ensure t...

Investigation on the mechanical properties of sagbama aggregate (flexural property)

ABSTRACTThis study investigation on the mechanical properties of Sagbama rice granite was analyzed to determine the load that would cause ultimate flexural stress on the material when used in concrete construction .This is necessary to make decision on where it is suitable for use. This study requires the production of 12 concrete beams of 100mmx100mmx500mm with sagbama rice granite as coarse and fine aggregate. Three (3) specimens were produced to be tested at 7, 14, 21 and 28days.Mix ratio ...

Design and Construction of an in-situ salinometer for agricultural soils

The increase of salinity in soil and water bodies which simultaneously declines the productivity of agriculture is of great concern to the Nigerian Federation which holds agriculture as a major means of survival for its economy. Thus, the proper monitoring,use and management of soil and water bodies is a sure way to proffer solutions to food shortage and poor crop yields. This can however be achieved by the use of a fast, reliable, and accurate in-situ salinometer. A portable in-situ salinome...

Broadband Network Penetration and Growth Pattern in North Eastern Part of Nigeria

Information and Communications Technology, like many other classical innovations has been institutionalized and become myths binding on organizations. How this seditious tool can be used as a catalyst for developing countries, in the face of empirical anomalies has been a cause for concern. Why does increasing number of agencies go on-line and establish similar web presences with similar structures even when delivery to end user is poor or near impossible? What are the processes of adapti...

Broadband – Infrastructural Deficit and ICT Growth Potentials in Cross River State, Nigeria

The study examined Broadband infrastructural deficit and the growth potentials of Information and Communications Technology in Cross River State of Nigeria, by using three–to-five scale closed-ended questionnaires. Cross River State has a population of about 3,104,446; yet by 2014, it was estimated that mobile Broadband connections in Cross River State was below 50,000 subscribers. Government statistics put Internet penetration in Nigeria at 28 per cent. Out of these, only less than 9 p...

Issues of Variance of Extreme Values in a Heterogeneous Teletraffic Environment

The reliability of various teletraffic data-analytical devices in communication systems is relevant to all stakeholders. Among other key external variables, the performance of the network evaluated under a variety of traffic scenarios is the focus of the study: data / video traffic generated by subscribers, who ordinarily subscribed voice bandwidth services. This study, therefore views teletraffic data as complete random and in-deterministic variables, and examines its continuous dependenc...

Issues Associated with Decimeter Waves Propagation at 0.6, 1.0 and 2.0 Peak Fresnel Zone Levels

Radio waves propagation is dependent on many variables. Any of these variables employed must ensure that the antennae at both sides of the link can see each other. This is because the radio horizon extends beyond the optical horizon. Inspite of this porch, telecommunications’ long distance signal suffer degradation. The ratio of the transmitted power to the receiver power is empirically deteriorated. The level of the received signal fluctuation is usually a function of the configured cha...

DESIGN AND CONSTRUCTION OF A GSM-BASED MULTI-PURPOSE MEASURING DEVICE FOR UHF SIGNAL STRENGTH LEVELS.

It has become common for many business entrepreneurs to move with two or three mobile phones at any particular time in Nigeria. The reason is usually anchored on the epileptic reception of the telecommunications networks and their desire to keep in touch with their businesses. This burden can be made lighter if signal strength levels of Telecommunications’ operators can be periodically measured and predicted without resorting to the Network operator; like weather forecasting. The de...

Unmanned Aerial VehiclePitch Optimization for Fast Response of Elevator Control System

The flight dynamicsof an Unmanned Aerial Vehicle(UAV)is the science ofitsorientation and control in three dimensions.The three primary orientations include: the Pitch, the Roll and the Yaw. Therear part of the tailplaneis known as the elevatorcontrol ofanUAVpitch (therotating around the transversal axis). Flight route deviations and flight altitude variations due to hash weather conditions such as shock waves or thunder storm and the wind speed/direction during flight gre...

Design of a Robust PID Controller for Improved Transient Response Performance of a Linearized Engine Idle Speed Model

One of the advantages of automatic control system is its application to the regulation of internal combustion engines. An area of significance in fuel energy reduction and efficiency improvement is the control engine idling speed. This paper has presented a control system for improved transient response performance of a linearized engine idle speed model. In order to realize the aim of the work, nonlinear dynamics of engine idle speed are obtained and were later linearize...

THE IMPACT OF SUPERVISION ON EMPLOYEES EFFECTIVENESS IN ORGANIZATION (A CASE STUDY OF SELECTED MINISTRY OF EDUCATION OWERRI, IMO STATE)

ABSTRACT This study on the Impact of Supervision on employees effectiveness in Organization focused on the ministry of Education Owerri, Imo State. The study used Survey Design technique. The population of the study consists of 110 staff of the ministry of Education while Yaro Yamen formula was used to determine the sample size. Both primary and Secondary sources of date were used while a 14 Hem structured questionnaire was the main instrument of data collection, the sample per...

The economic analysis of gas pipeline construction for the evacuation of natural gas from a gas processing facility to a gas fired power

ABSTRACT   The site of electrical power plants has been a subject of interest since the advent of electricity and the distance between energy sources (mines, oil and gas fields, and water bodies for renewable energy) and distance load (cities and industrial hubs) centres. The quest for sufficient energy infrastructure to supply Nigeria’s huge and growing population of about 190 million and also to power the much-anticipated industrialization and economic growth and developm...
