    Vibration Characterization of the Human Knee Joint in Audible Frequencies (2020)
    Molecular Diversity Preservation International

    Publication Date: 2020-07-25
    Description: Injuries and disorders affecting the knee joint are very common in athletes and older individuals. Passive and active vibration methods, such as acoustic emissions and modal analysis, are extensively used in both industry and the medical field to diagnose structural faults and disorders. To maximize the diagnostic potential of such vibration methods for knee injuries and disorders, a better understanding of the vibroacoustic characteristics of the knee must be developed. In this study, the linearity and vibration transmissibility of the human knee were investigated based on measurements collected on healthy subjects. Different subjects exhibit a substantially different transmissibility behavior due to variances in subject-specific knee structures. Moreover, the vibration behaviors of various subjects’ knees at different leg positions were compared. Variation in sagittal-plane knee angle alters the transmissibility of the joint, while the overall shape of the transmissibility diagrams remains similar. The results demonstrate that an adjusted stimulation signal at frequencies higher than 3 kHz has the potential to be employed in diagnostic applications that are related to knee joint health. This work can pave the way for future studies aimed at employing acoustic emission and modal analysis approaches for knee health monitoring outside of clinical settings, such as for field-deployable diagnostics.

    Estimation of biomass and optimum of shrimp fishing season in Hormuzgan Province (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: This project was designed with for objective on estimation of Biomass and optimum time for catch season of P.merguinsis and M.affinis shrimps. This investigation was carried out monthly by swept area method in coastal waters of Hormozgan province. The optimum time for fishing season in Bandar Abbas to Sirik waters in 2004,2005 and 2006 respectively was about 25/9/2004, 24/9/2005 and 25/9/2006. Total allowable catch ( T.A.C.) for P.merguiensis and M `.affinis estimated in 2004 to 2006 were 600 , 170 tonnes , 850 , 550 tonnes and 650 , 400 tonnes respectively. The densest catch was obtained for P.merguiensis ( from 58/5 to 65/5 %) and the least catch for P.indicus ( from 0/04to 1/1 % ), respectievly.

    A study on stocks of Trap's Fishes in Abumusa Island (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: This report is about coral-reefs around Abumosa lsland from January 1998 till February 1999 by trap and underwater visual census. Total species belonging to genus and family were idemtified and length-weight relationship were estimated for more frequent species. Small tooth emperor (Lethrinus microdon) was predominate from other species. Catch per unit of effort (cpue) calculated for each trap (large, medium and small). Efforts were based on number of trap and day. Cupue of small and large traps was further in late summer compare other seasons. Results of catch analysis showed that no differ catch value (eatable, fishes, ornamental fishes and total catch) between small-medium and medium-large traps. Value catch wasn’t significant difference between three depth (0-10, 10-20 and 20-30m) and four geographical side, too. But, catch value of ornamental fishes was significant difference between depths 0-10 and 20-30 meter.
