A SIMPLE FORMULA FOR INSERTION LOSS PREDICTION OF LARGE ACOUSTICAL ENCLOSURES USING STATISTICAL ENERGY ANALYSIS METHOD

A simple formula for insertion loss prediction of large acoustical enclosures using statistical energy analysis method

Insertion loss Bread Bin prediction of large acoustical enclosures using Statistical Energy Analysis (SEA) method is presented.The SEA model consists of three elements: sound field inside the enclosure, vibration energy of the enclosure panel, and sound field outside the enclosure.It is assumed that the space surrounding the enclosure is sufficient

Improvement of Nemadectin Production by Overexpressing the Regulatory Gene nemR and Nemadectin Biosynthetic Gene Cluster in Streptomyces Cyaneogriseus

Nemadectin, a 16-member macrocyclic lactone antiparasitic antibiotic, is produced by Streptomyces cyaneogriseus subspecies noncyanogenus.Moxidectin, a C-23 oximate derivative of nemadectin, is widely used as a pesticide due to its broad-spectrum, highly efficient, and safe anthelmintic activity.NemR, a LAL family regulator, is encoded by nemR and i
