The Delta Analysis 
A Detailed Study of the Energetics, Emittance, Dimensions and Radiobiological Properties of Delta Rays

This research aims to study the beam properties of delta electrons and establish experimental data to extrapolate the potentially useful applications of 𝛿-rays. The 𝛿-rays have very little penetration, from few micrometers to millimeters in human tissue. This property might show promising results in its radiobiological use. Moreover, the radial dose distribution, beam emittance, linear energy transfer, and other properties of delta rays can help us find other prospective areas for its use. It is the first piece of literature pointing out applications of 𝛿– rays. This research makes a detailed analysis of the methods of studying 𝛿-rays and presents possibilities of the overwhelming importance of these secondary electrons in the contemporary scientific researches of particle physics and biophysics; primarily for the treatment of cancer-like ailments.

Purity Standards for Pure Mustard Oils
On the Comparative Studies of the UV-Vis Spectrum of Pure Mustard Oil and its Variants in Nepal

UV-Visible Spectroscopy is a non-invasive, fast, efficient, and cheap method to prove the quality of mustard oils. Three samples of pure mustard oils have been collected from Khokana, Lalitpur and their UV-Visible Spectrums in the range of 295 – 850 nm have been reported. The pure and roasted Nepali mustard oil showed two distinct absorbance peaks in the range of 300 – 350 nm while the pure and roasted Indian oil as well as pure and unroasted mustard oil showed only one characteristic peak in that spectral region. Moreover, the characteristic peak present at around 450 nm range infers the possibility of presence of Maillard reaction products in mustard oils; more in the roasted ones than the unroasted. The hope of this research to set the purity standards for the pure mustard oil variants consumed in Nepal by presenting the findings of the experiment conducted in the Nanotechnology Research Laboratory, RECAST, TU.

Accretion Stream of Magnetic Cataclysmic Variable AM Herculis
On the Modeling of Inhomogeneous Accretion Flow of Polar Variable AM Her via Infrared Spectroscopy of Cyclotron Emissions

Polar Cataclysmic Variable AM Herculis is characterized by linear and circular polarization present in the cyclotron emissions in the IR Region of 1-2.5 micrometers. Wickramasinghe, Ferrario, Bailey, Meggit and others have tried to propose different stream models including point-like, cylindrical, arc-shaped and ridge shaped based upon IR Spectroscopic data and calculations. But, all of these models seem to have an inherent flaw of assuming homogeneity of the mass accretion on the primary white dwarf. We are trying to introduce pressure and mass gradient with dense core and relatively scarce periphery of the accreting stream to create an inhomogeneous stream model that fits the spectroscopic and polarimetric data for AM Her and may serve as the principle model for all other polar CVs.

Solar Devices Tilt Angle
On the Optimization of Tilt Angles of Solar Devices for Maximum Energy Absorption in the Context of Nepal 

It is clear that solar devices are the gateway to abundant green and clean energy. In the case of Nepal, it is even more useful as its latitude is near equatorial region (26-30 degrees N) resulting in year-long exposure to solar radiation. This research serves to analyze the daily, monthly, yearly insolation of Nepal and find out the optimal tilt angle for highest efficiency of PV modules. Extensive data analysis and mathematical modeling of various meteorological and radiation parameters has been done to establish accurate and reliable results. Models from Liu and Jordan, Perez, Kluchner, Hay and Davis and others have been compared to incorporate the changes due to isotropic and anisotropic behavior of diffused radiation. This piece of literature points out that by manual changes of tilt angle of solar devices on monthly basis results in greater increase of efficiency.

Fungi: The Supreme Resource
On the Development of Fungi-based Ecosystem And Sustainable Martian Society

Since humans next interplanetary expedition lies on Mars, we must focus on ways to manifest supreme sustainability of Martian Life. Fungi can serve as an all round resource to solve all major problems on Mars like unfavorable meteorological conditions, over exposed radiation, dependency for nutrition on earth, lack of raw material for anthropogenic construction and ecological succession in nudation phase. We propose three-layered Fungi dome structure for settlement and protection of radiation, fungi-invasion as the start of ecological cycle, food production form fungi and making construction materials via Myco-architecture. Species like Cryptomyces antarticus will be the start of fungi-based sustainable and self-efficient ecosystem on Mars.

Pandemic Preparedness Index (PPI)
On the Statistical Multi-dimensional Processes for the Comparative Analysis of the Socio-economic Status among Geopolitical Regions

In this paper, we develop a Composite Indicator that serves as a statistical tool to assess the pandemic preparedness of a region. A large amount of mathematical modeling of the theoretical framework has been done using normalization, imputation, PCA, weighting, and aggregation. 25 original equations formulated by assigning new symbols are prepared for transparency and accountability. The method of building the indicator is generalized for N-dimensional datasets, hence making it more powerful. The results and the final scores of Asia, Europe, and the USA have been visualized using charts. We suggest that Pandemic Preparedness Index (PPI) can cause a revolution in policy making considering statistics. 

Anomalous Hall effects in Co3Sn2S2
 On the Study of  Berry Curvature Effects on Magnetic Weyl Semimetal Candidate Co3Sn2S2

The Magnetic Weyl Semimetals with broken time-reversal symmetry usually generate Anomalous Hall effects due to considerable Berry Curvature. We try to calculate these field effects for Co3Sn2S2, which is a ferromagnetic kagome-lattice semimetal with quasi-two-dimensional crystal structure. This research will try to provide further insights on the behaviors of Berry Curvature Effects also taking into account the Band Structures. The hope of this research is to establish Co3Sn2S2 as a great candidate for quantum observations of the Anomalous Hall effects. (Calculations are ongoing…)

Golden Ratios and Renaissance Arts
On the analytical study of Golden Ratios and Fibonacci sequences in the Renaissance Arts

The Golden Ratio or Golden Proportion (Φ) represents an irrational mathematical constant, 1.6180339887 approximately. Due to its relation to visual aesthetics, the Renaissance artists employed these proportions in their paintings. Many researchers, psychoanalysts, and mathematicians have extensively studied this ratio and analyzed the geometric and psychological implications of this ratio. Golden Ratio, which is also known as Golden Section, is mathematically related to the convergence of Fibonacci sequence ratios and simply the ratios of longer and shorter sides in a geometric shape. This paper presents an in-depth exposition and analysis of five major High Renaissance arts, namely Salvator Mundi, Creation of Adam, Birth of Venus, Doni Tondo, and The Ambassadors. Using PhiMatrix software, the Golden Sections in the key components of these artistic compositions have been displayed and interpreted, both structurally and exquisitely. Moreover, the shreds of evidence of perceptible sensations of golden sections have been analyzed through a review of typical scientific experiments in psychoanalytic studies of Golden Ratio in relation to attractiveness. This piece of literature serves as an explicative merger of analytical geometry with art history and develops insights for future artists and researchers about the marvels of the Golden Ratio in artistic expressions.

Technology Adoption in Nepal
On the Technology Adoption Status of Nepalese Secondary Level Students: Causalities, Inferences and Ways Ahead

Technology Adoption is a prominent factor to mark overall progress of a nation in the 21st century. When world has already experienced digital revolution, Nepal is still in the phase to adopt mainstream IT facilities available. The condition of Secondary Level Students become a major concern since they are the future leaders of the nation. This research depends on mass survey to analyze attitudinal, pedagogical, economical, parental and administrative aspects affecting tech adoption and tries to find the causes, correlations, and potential solutions to promote tech usage among students.

Quantum Tunneling
On the Effects of Internal Motions of Molecules in Quantum Tunneling via Quantum Dissipation and Decoherence

This research was a part of Students Research Council Nepal (SRCN) in which our team investigated the factors affecting quantum tunneling in chemical and physical processes. We added insights about how quantum decoherence and dissipation results in significant change in the probability of tunneling. Internal motions, including translational, rotational and vibrational, might affect tunneling rates through an energy barrier. However, the rigorous mathematical modeling is yet to be done for these probable effects. (This research is ongoing for more than 9 months and is expected to be completed by late November.)
