the 3D3A lab is conducting detailed measurements of the directivity of various loudspeakers measured in the lab's anechoic chamber. At present the database contains the measured directivity data for six loudspeakers: 1. Ascend Acoustics CBM-170 2. GedLee Nathan 3. Genelec 8030a 4. Manger Sidekick 5. Spendor SA1 6. Tannoy Definition DC6i (Concentric)
On June 10, 1955, the laying of the foundation stone of the European Organization for Nuclear Research Laboratory (CERN) was performed by Felix Bloch, the organization's first President. Since 1955, numerous essential experiments were executed, leading to significant contributions in the world of physics and to our daily lives.
This study sought to investigate the relationship existing between laboratory facility availability and students’ academic performance in Biology across Secondary School in Ethiope East L.G.A., of Delta State, Nigeria. In the course of this study, three research questions were developed and three null hypotheses were formulated. The study used was delimited to senior secondary schools two (SSII) because it is at this stage students are being exposed to practical activities that require the usage of laboratory facilities and equipment. A descriptive survey design was used while the sample of the study was made up of one hundred and three (103) respondents. The study employed a questionnaire as an instrument to gather data.
