Somatic Embryogenesis and Plantlet Regeneration in the Carica papaya L. cv. Eksotika
A highly efficient protocol for regeneration of Carica papaya L. cv. Eksotika somatic embryos from immature zygotic embryos was developed. This study was designed to overcome the obstacles in regeneration of somatic embryos from immature zygotic embryos of āEksotikaā,
especially problems associated with formation of better root quality and callus formation at the base of somatic embryos. Somatic embryos were generated by incubation of immature zygotic embryos in half-strength salt Murashige and Skoog (MS) medium with full-strength vitamins supplemented with 7.5 mg Lā1 2,4-D, 100 mg Lā1 L-glutamine, 50 mg Lā1 myo-inositol, 45 mg Lā1 adenine sulphate, 0.33% gelrite, and 6% sucrose, followed by transfer to maturation medium consisting of Ā½ MS
medium supplemented with 5 mg Lā1 phloroglucinol, 100 mg Lā1 L-glutamine, 100 mg Lā1 myoinositol, 68 mg Lā1 adenine sulphate, 0.38% gelrite, and 3% sucrose. After that, well-formed somatic embryos were transferred to MS medium containing 3% sucrose and 0.8% agar for shoot production. The embryos were elongated in MS medium supplemented with 1 mg Lā1 gibberellic acid, 0.5 mg
Lā1 indole-3-butyric acid, 100 mg Lā1 myo-inositol, and 3.76 mg Lā1 riboflavin. Root regeneration was
achieved on MS medium containing 7.9 mg Lā1 phloroglucinol and supported with vermiculite after
4 days of cultivation on Ā½ MS medium with 2 mg Lā1 indole-3-butyric acid. After the rooting phase,
in vitro plantlets were acclimatized in peat moss soil
Vitis Elegan as a Promising Antidiabetic Herb: Phytochemical and Pharmacological Assessment
In this research, we investigated the antidiabetic activity of Vitis elegans rhizome, which is used as traditional treatment for diabetes mellitus. The methanol, chloroform, petroleum ether, and hexane extracts of the plant root were obtained through serial exhaustive extraction and were analyzed by Thin Layer Chromatography (TLC).Ā Glycogen phosphorylase (GP) assay was done to determine the inhibitory effects of respective extracts on GP enzyme. Total phenol content was measured using the Folin-Ciocalteu method and brine shrimp test was done to evaluate the toxicity of the extracts. Evaluation of TLC plates alone and after spraying with different reagents indicated that terpenoid was the major component of the sample followed by alkaloid and phenol. Chloroform extract applied more inhibitory effects on GP enzyme activity with percentages of 39.65 in concentration of 2.5 mg/ml. This suppression effect was higher than glucose, as a standard inhibitory agent in the body. The highest amount of phenol was found in the methanol extract, equal to 49 mg GAE g-1. Petroleum ether, chloroform and methanol extracts were considered as non-toxic solvents with LC50 values of 8.9, 3.5 and 3.7 mg/ml respectively. While hexane with 0.089 mg/ml LC50 value was classified as toxic extract. Based on the results of this study, we concluded that Vitis elegans rhizome, has the potential to be further studied for anti-hyperglycemic properties
Measurements of a 5:1 blood pump model
This report presents the study of the flow behaviour of the fluid in the clearance gap of a scaled up model of the Kyoto-NTN Magnetically Suspended Centrifugal Blood Pump (MSCBP). The scales up model is 5 times by applying dimensional analysis. MSCBP was used among the other conventional ventricular assist devices as it has a lower haemolysis and thrombus formation. A hot wire anemometry is used in this study to measure the gap velocity in the clearance gap of 1mm in the scaled up model. Measurements of tangential and radial velocity at different radial and angular positions are taken. The angular positions are at intervals of 5 degrees for each measurement. The hot wire probe will also mounted at 3 different protrusion depths which are 0.25mm, 0.5mm, 0.75mm from the wall of the pump casing. The results of the tangential and radial velocity allow us to gain an understanding of the resultant velocity and the flow angle of the fluids for different depths. The results show that the tangential flow velocity plays a more significant role than the radial velocity in the flow behavior of the fluid. There was no re-circulation and the washout mechanism is more significant at the splitter plate at 180 degrees of angular position. This experimental study of the flow behavior can help in future studies of the blood pump and in optimizing it.Bachelor of Engineering (Mechanical Engineering
A Review of Structural Performance of Oil Palm Empty Fruit Bunch Fiber in Polymer Composites
According to environmental concerns and financial problems, natural fibers have become interesting and fascinating nowadays to be used as an industrial material and structural material for rehabilitating of structures. Oil palm empty fruit bunch fiber (OPF) is a natural fiber which is found a lot in tropical areas. Scientists have used OPF fiber with many types of resins such as epoxy, polypropylene, polyester, and phenol formaldehyde. Therefore, this paper focused on the properties of OPF fiber and gathered mechanical properties of OPF composites (OPF as reinforcement of polymer) reported by other researchers in terms of tensile and flexural properties. Furthermore, the chemical surface modification methods to solve the interfacial bonding of fiber and polymer were mentioned. In addition, the results of hybrid composites of OPF were also discussed in this paper. Meanwhile, the results of composites were compared to pure resin properties and also the stress-strain diagram and internal strain energy of composites were considered. Besides, the effects of adding OPF to other composites to make a new hybrid composite were indicated. Finally, it is clear that the use of oil palm fiber composites for structural elements for bearing loads is not recommended but the usage of OPF composites for secondary structural elements may be recommended due to future researches
Halal tourism based on local wisdom in Madura: Opportunities and challenges
Religious and spiritual tourism have been increasingly common and well-liked in recent decades, representing a large portion of global travel and expanding rapidly in recent years. The phrase "hidden paradise" is used to describe the island of Madura, which spans four regenciesāSumenep, Pamekasan, Sampang, and Bangkalanāand offers a variety of tourism opportunities, including historical tourism, natural tourism, cultural tourism, and religious tourism. This study aims to define halal tourism themes using conventional wisdom from the region. In this study, a case study with a qualitative descriptive methodology is used. In-depth interview and observation data were used as the primary sources, and books, the internet, and documentaries were used as the sources for the secondary data. According to the study, Madurese people have a limited comprehension of the idea of halal tourism and are therefore unable to implement it according to local wisdom
