An Efficient and Easy Micro-propagation of Reseda Lutea (Resedaceae) a Rare and Medicinally Valuable Plant of Saudi Arabia

The goal of this work was to look at the propagation of Reseda lutea L. by organogenesis in tissue culture. Explants from in vitro grown seedlings were taken from the axillary bud. After seven days of culture on MS medium supplemented with 1.0 mg/l BA, the adventitious buds developed. After three weeks of culturing on MS medium supplemented with 1.5 mg/l BA, the maximum multiplication of shoots (16.12 shoots/explant) was discovered, with an average (7.37 cm) shoots/explant. These shoots were sub-cultured on MS media with varying concentrations of NAA and IBA for root initiation. The MS medium combined with IBA produced the greatest percentage of root development (92%) and the greatest number of roots (7.37 roots/plant). In MS media supplemented with 0.5 NAA, the longest roots (3.08 cm) were found. After 17 days in a glasshouse, the plantlets were acclimatized in pots containing Peat moss and pearlite, 98 percent of the plantlets were acclimatized. To get a plant in a pot, the complete procedure took about 75 days. The technique proposed could aid in the preservation of the plant both in vivo and in vitro.

Gamification and its Applications

In the recent past, gamification is a new buzzing word and is used frequently by researchers in particular in the area of management. Gamification is applying gaming and using gaming components and procedures in a non-gaming environment. The three main components of gamification are game elements – a design prototype which can be integrated into the game; game design – A complete procedure building engaging games, based on business objectives, technical feasibility and management expectations; the last one is the non-game environment – The non-gaming environment is the components involved in real-world business and social impact objectives and goals. If gamification is applied correctly in a business or social environment, the results will be amazing and can inspire the business community decisions. Gamification can be the future of the business and can make the business environment the gaming components fun and those fun and appealing components can be applied in real-life business activities. To make gamification effective the game dynamics, game design, behavioural change, and motivation are the aspects that need to be combined applied in non-gaming environment. This brief note presents the main ideologies that can the gamification design in the business environment more successful. The author also narrates whene the gamification procedures can be useful in the business world.

MRI-based 3D retinal shape determination

ObjectiveTo establish a good method to determine the retinal shape from MRI using three-dimensional (3D) ellipsoids as well as evaluate its reproducibility.Methods and analysisThe left eyes of 31 volunteers were imaged using high-resolution ocular MRI. The 3D MR-images were segmented and ellipsoids were fitted to the resulting contours. The dependency of the resulting ellipsoid parameters on the evaluated fraction of the retinal contour was assessed by fitting ellipsoids to 41 different fractions. Furthermore, the reproducibility of the complete procedure was evaluated in four subjects. Finally, a comparison with conventional two-dimensional (2D) methods was made.ResultsThe mean distance between the fitted ellipsoids and the segmented retinal contour was 0.03±0.01 mm (mean±SD) for the central retina and 0.13±0.03 mm for the peripheral retina. For the central retina, the resulting ellipsoid radii were 12.9±0.9, 13.7±1.5 and 12.2±1.2 mm along the horizontal, vertical and central axes. For the peripheral retina, these radii decreased to 11.9±0.6, 11.6±0.4 and 10.4±0.7 mm, which was accompanied by a mean 1.8 mm posterior shift of the ellipsoid centre. The reproducibility of the ellipsoid fitting was 0.3±1.2 mm for the central retina and 0.0±0.1 mm for the peripheral retina. When 2D methods were used to fit the peripheral retina, the fitted radii differed a mean 0.1±0.1 mm from the 3D method.ConclusionAn accurate and reproducible determination of the 3D retinal shape based on MRI is provided together with 2D alternatives, enabling wider use of this method in the field of ophthalmology.

Influence of Tubercle Modifications on the Performance of Marine Vertical Axis Propellers

Even though past efforts in computational fluid dynamics (CFD) simulations have shown great progress in the implementation of tubercles into aero-foils and turbines blades, incorporating these tubercles into marine vertical axis propellers is still comparatively less well understood. In general, the performance of marine propellers is highly related to the pressure and velocity distributions over the propeller blades. Since the presence of tubercles’ serrations in the blade leading edge can vary these distributions over the blade, the performance of the propellers can be enhanced. In this article, tubercle modifications are investigated in marine vertical axis propellers through the use of CFD simulation. To achieve this purpose, a complete procedure of CFD simulation using ANSYS FLUENT 16 is proposed. Obtained CFD results are validated using direct comparison with the previous analytical studies. Obtained performance characteristics of the modified vertical axis propeller are assessed against the available characteristics of the baseline one. The CFD results are found in a good agreement with the analytical ones. Moreover, the results demonstrate the improvement of the obtained performance of the modified vertical axis propeller compared to the baseline one in terms of increased thrust coefficient and higher efficiency over the considered range of advance ratio. Introduction Shallow waters, rivers, and seas; the presence of obstacles; the complexity of water routes; and the territorial orography require the availability of effective maneuverability to enhance marine propulsion compared to the traditional rudder-propeller system (Pasetto1 2013). In this context, the vertical axis propellers (VAP) can be a real and valid alternative to the rudder-propeller system (Chen 2007), allowing the ships to navigate in an effective way also in the difficult routing and in shallow water conditions (Carlton 2007). The VAP provides the ability to sail vessels in all sea conditions effectively. It maintains the ability to direct the thrust to 360° and, consequently, provides a better performance in terms of maneuverability, stop and crash maneuvers and higher efficiency. It is therefore necessary for all kinds of vessels requiring high level of maneuverability in congested waterways to be equipped with VAPs for ease, safety, and immediate response.

A MANAGEMENT OF YAKRIT VRIDDHI (HEPATOMEGALY) BY SHODHANA CHIKITSA (VIRECHANA) FOLLOWED BY SHAMAN CHIKITSA (ARKA MAKOI): A CASE STUDY

A 39-year-old man with clinical sign and symptoms of poor appetite, nausea, fatigue, distend abdomen, increased abdominal size and shape, abdominal pain, indigestion, vomiting sensation diagnosed as Yakrit Vriddhi or Yakrit-dalodar (Hepatomegaly). As per Ayurveda Samhita Shodhana Chikitsa is more effective in such type of patient. In this case after the routine examination i.e., History, Palpation, Blood Investigation (LFT), and Ultrasonography patient was treated by Panchakarma treatment. (Bio-purification therapy) In this Poorva Karma (Snehan- Bahya/Abhyantara) and Pradhana Karma (Abhayadimodak - Virechana Karma) in which vitiated doshas were expelled through Adhomarga (Anal route). After the Virechana Karma for restoration of the body Sansarjana Karma (Ayurvedic Dietary & Behavior regimen) was also done. The patient was on purgation 26 times (Vegas). At the end of the virechana karma Kapha was presented in the stool (Kaphant-Virechana). After the complete procedure followed by palliative treatment with Arka Makoi (Solanum nigrum) patient felt remarkable relief from above cited symptoms i.e., poor appetite, nausea, fatigue, distend abdomen, increased abdominal size and shape, abdominal pain, indigestion, vomiting sensation. The therapeutic purgation is safe and effective Panchakarma protocol to eliminate the morbid Pitta Dosha in the body either by pathological condition or diet and behavioral mismanagement.

Metrological characterisation of rotating-coil magnetometer systems

Rotating-coil magnetometers are among the most common and most accurate transducers for measuring the integral magnetic-field harmonics in accelerator magnets. The measurement uncertainty depends on the mechanical properties of the shafts, bearings, drive systems, and supports. Therefore, rotating coils require a careful analysis of the mechanical phenomena (static and dynamic) affecting the measurements, both in the design and in operation phases. The design phase involves the estimation of worst-case scenarios in terms of mechanical disturbances, while the operation phase reveals the actual mechanical characteristics of the system. In previous publications, we focused on modelling the rotating-coil mechanics for the design of novel devices. In this paper, we characterise a complete system in operation. First, the mechanical model is employed for estimating the forces arising during shaft rotation. Then, the effect of the estimated disturbances is evaluated in a simulated measurement. This measurement is then performed in the laboratory and the two results are compared. In order to characterise the robustness of the system against mechanical vibrations, different revolution speeds are evaluated. This work thus presents a complete procedure for characterising a rotating-coil magnetometer system.

EPOS: EEG Processing Open-Source Scripts

BackgroundSince the replication crisis, standardization has become even more important in psychological science and neuroscience. As a result, many methods are being reconsidered, and researchers’ degrees of freedom in these methods are being discussed as a potential source of inconsistencies across studies.New MethodWith the aim of addressing these subjectivity issues, we have been working on a tutorial-like EEG (pre-)processing pipeline to achieve an automated method based on the semi-automated analysis proposed by Delorme and Makeig.ResultsTwo scripts are presented and explained step-by-step to perform basic, informed ERP and frequency-domain analyses, including data export to statistical programs and visual representations of the data. The open-source software EEGlab in MATLAB is used as the data handling platform, but scripts based on code provided by Mike Cohen (2014) are also included.Comparison with existing methodsThis accompanying tutorial-like article explains and shows how the processing of our automated pipeline affects the data and addresses, especially beginners in EEG-analysis, as other (pre)-processing chains are mostly targeting rather informed users in specialized areas or only parts of a complete procedure. In this context, we compared our pipeline with a selection of existing approaches.ConclusionThe need for standardization and replication is evident, yet it is equally important to control the plausibility of the suggested solution by data exploration. Here, we provide the community with a tool to enhance the understanding and capability of EEG-analysis. We aim to contribute to comprehensive and reliable analyses for neuro-scientific research.
