“…In contrast, induction of rooting of G. scabra was obtained on NAA (0.3 mgL −1 ) and IAA (0.1 mgL −1 ) containing media 38 . Similarly higher percentage of rooting were obtained in half strength MS media with NAA (1.0 mgL −1 ), were as full strength medium with NAA (1.5 mgL −1 ) was the best media for rooting 10 . Bekheet (2013) 39 has indicated that addition of IAA, IBA or NAA (1 mgL −1 ) induced rooting of in-vitro grown P. dactylifera .…”

Efficient protocols for callus induction and micro propagation of Saussurea costus (Falc.) Lipsch were developed and phytochemical diversity of wild and in-vitro propagated material was investigated. Brown and red compact callus was formed with frequency of 80–95%, 78–90%, 70–95% and 65–80% from seeds, leaf, petiole and root explants, respectively. MS media supplemented with BAP (2.0 mgL−1), NAA (1.0 mgL−1) and GA3 (0.25 mgL−1) best suited for multiple shoot buds initiation (82%), while maximum shoot length was formed on media with BAP (1.5 mgL−1), NAA (0.25 mgL−1) and Kinetin (0.5 mgL−1). Full strength media with IAA (0.5 mgL−1) along with IBA (0.5 mgL−1) resulted in early roots initiation. Similarly, maximum rooting (87.57%) and lateral roots formation (up to 6.76) was recorded on full strength media supplemented with BAP (0.5 mgL−1), IAA (0.5 mgL−1) and IBA (0.5 mgL−1). Survival rate of acclimatized plantlets in autoclaved garden soil, farmyard soil, and sand (2:1:1) was 87%. Phytochemical analysis revealed variations in biochemical contents i.e. maximum sugar (808.32 µM/ml), proline (48.14 mg/g), ascorbic acid (373.801 mM/g) and phenolic compounds (642.72 mgL−1) were recorded from callus cultured on different stress media. Nonetheless, highest flavenoids (59.892 mg/g) and anthocyanin contents (32.39 mg/kg) were observed in in-vitro propagated plants. GC–MS analysis of the callus ethyl acetate extracts revealed 24 different phytochemicals. The variability in secondary metabolites of both wild and propagated plants/callus is reported for the first time for this species. This study may provide a baseline for the conservation and sustainable utilization of S. costus with implications for isolation of unique and pharmacologically active compounds from callus or regenerated plantlets.

“…Growth regulators such as 2,4-D (0.25, 0.5, and 1.0 mgL −1 ) in combination with varied concentration of Kinetin (0.5, 1.0, 1.5 and 2.0 mgL −1 ), and four explants types (seeds, leaf, petiole and internode) were compared for callus induction. Explants were subjected to two subcultures at an interval of fourteen days 10 .…”

“…Hossain et al [35] employed the finite element method to simulate the vibration of a mini cantilever beam partially submerged in a viscous media, and the beam was found to be the most sensitive to respond in resonant frequency and Qfactor when the beam was submerged by one-third in viscous media. Hossain et al [36] also applied finite element analysis (FEA) to characterize the rheological properties of viscous materials by predicting the dynamic response of a cantilever beam partially submerged in air and water. Kwak et al [37] used the virtual mass method to investigate the free flexural vibration of a cantilever plate partially submerged in fluid, and the influence of the virtual mass was expressed in analytical form in terms of the Mathieu function.…”

In order to obtain the effects of time-varying fluid on dynamical characteristics of cantilever beams, this paper gives a comprehensive study of cantilever beams vibrating in a fluid with variable depth. The mathematical model of the cantilever beams in time-varying fluid is derived by combining Euler–Bernoulli beam theory and velocity potential theory, and the influence of the time-varying fluid is discussed. Then, a two-way fluid-structure interaction (FSI) numerical simulation procedure is proposed to calculate the transient responses of the beam. The validity and accuracy are verified according to the comparison among theoretical analysis, numerical simulations, and experimental measurements. Results show that, besides the added mass effect, a damping-like term is also induced due to the motion of the fluid, which is proportional to the moving velocity of the fluid. Both the added mass and the added damping increase with the increment of the width of the beam. The surrounding fluid near the free end affects the beam more significantly. As a negative damping is caused while the fluid decreases, resulting in a much slower decay of the time responses. Therefore, the added damping should not be neglected in the analysis of the FSI problems with time-varying fluid.

“…The hydrostatic pressure is used because it studies the characteristics of fluids in particular liquids [13]. In addition, the Hooke's law and hydrostatic pressure are also concepts that are still considered difficult by students in high school as evidenced by their learning outcomes, which is still low [14].…”

Physics learning cannot be separated from the existence of physics measuring instruments, but their existence in schools are very limited. Therefore, creativity and innovation are needed to develop physics measuring instruments that are easily accessible by schools. This research aims to design and construct a liquid density measuring instrument by applying Hooke’s law and hydrostatic pressure. The method used in this research is a quantitative descriptive method with the stages of designing, constructing, developing, and testing the measuring instrument. The design and construction of the measuring instrument in this study is carried out using tools and materials that are simple and easily obtained, such as a glass pipe, PVC pipe, rulers, springs, and wooden table. The liquids used to test the instrument are cooking oil, lubricant, and water. The measurement results of the liquid density using the measuring instrument are in accordance to the known value or the standard.
