FUTA dons develop positive pressure ventilator

A team of researchers from the Federal University of Technology Akure, FUTA has developed a positive pressure ventilator, a variant of mechanical ventilator.
Presenting the prototype to the university authority, the Dean, School of Engineering and Engineering Technology SEET, Prof. Aremu Akintunde said the present design falls within the non-invasive mechanical ventilator category.
He said noninvasive mechanical ventilators come with covers and can be used at health facilities and at home because of its versatility adding that the design is of the Continuous Positive Airway Pressure (CPAP) type which delivers constant and steady pressure.
The system runs on direct current and can be configured to be powered by solar energy thus it has no direct negative effect on the environment.
Another unique advantage of the device is its portability as it can be used in ambulances in the case of emergency and it can also be used in Primary Health Care facilities in the rural areas. It is also configured in a way to run on car battery which carries 12 volts.

Explaining how the device works, Akintunde said that compliance and resistance for periodical dispensation of tidal volume was calculated and accomplished by using intermittent inspiratory and expiratory pause since normal breathing consists of an average Tidal Volume (VT) of 5ml/kg.
He said the machine was designed to dispense VT between 5ml/kg and 10ml/kg and that the machine has two parts namely the mechanical part which does the pumping of the air (Oxygen) while the electronic part offers the control and sensor of the mechanism.

18th Birthday

18th birthday in every human life is a very significant birthday and it's worth being celebrated.

We’re yet to have any meaningful engagement with Federal Government over strike, says ASUU

The Academic Staff Union of Universities (ASUU) has disclosed that it was yet to have any meaningful engagement with the Federal Government since the union embarked on an indefinite strike. The university teachers, had on March 23, 2020, embarked on strike in protest against government’s directive for members to join the integrated payroll and personnel Information System (IPPIS), payroll software mandated for all public officials. The Federal Government had last year directed that all its employees should be enrolled under the IPPIS scheme by December 31 or their salaries would be withheld. The directive did not go down well with ASUU members and they never failed to make it known to their employers. Few days to the deadline, some ASUU members were said to have secretly enrolled on the platform, while some others, especially their leaders, refused to join. All efforts to persuade them failed; rather they embarked on two weeks warning strike. The national president o

FUTO introduces a new faculty

 The federal university of technology Owerri has introduced a new faculty to suit the digital age. As earlier published today in their facebook page .. in accordance with the digital age and 21st century requirements, the FUTO management under the watch of their vice chancellor professor Francis chukwuemeka Eze, FNIP is once again recorded a feat. The aforementioned achievement is connected with the introduction of a new faculty which was done in line with the present realities. The faculty in question will be known and adressed as school of electrical system engineering technology (SESET). It'll House the following departments: - Electrical and Electronic Engineering (EEE) - Mechatronics Engineering (MEC) - Telecommunication engineering -  computer Engineering - Electrical power system Engineering It's note worthy that a Dean has already be appointed  to oversee the helm of affairs of the new school. He’s known by the name prof. Michael C. Ndinechi. They've congratulated t
