Spiritual Well Being A Protective Resource Among Youth of Arunachal Pradesh

Modernisation of a nation, besides yieldingpositive outcomes, has also ushered in various negative constructs, one of the chief being the growth of spiritual threats. Spiritual well-being provides reasons for one’s existence,increases resilience and provides stability for an overall development of a healthy, secure nation. Therefore, risk to spiritual well-being has immense negative impact on the mental state of an individual, especially, the youth. The ingrained spirituality in the culture of Arunachal Pradesh working as a protective buffer, and the status of the students being an educated class give the tribal students of the state, a powerful role in shaping the future security and progress of the society. Considering this implication, the present paper tries to explore how spiritual well-being and its two dimensions, namely, religious and existential well-being, are related to satisfaction with life, positive affect, negative affect and resilience. The Spiritual Well-being Scale, The Satisfaction With Life Scale, Positive Affect Negative Affect Schedule and The Brief Resilience Scale were administered to 100 university students, age ranging from 22-28 years. Results revealed that spiritual well-being was positively related to higher satisfaction with life, positive affect and resilience and negatively with negative affect. Implications of the studyhave also been discussed

Nanotechnology in Cancer Detection and Treatment

 Nanotechnology has taken great strides in the field of medicine with improved drug delivery systems. The application of nanoparticles in cancer detection and treatment has been prominent in recent years wherein unique properties can be utilized for detection of site specific tumors. The main objective of this review is to give an update on the available techniques and briefly describe the nano-medicines developed so far for an effective treatment. Conventional techniques face the problem of toxicity resulting from the administered drug. In addition to this, most of the techniques available detect cancer only after metastasis which hampers the effectiveness of the anti-cancer drug. Through the application of nanotechnology techniques, active cancer cells can be differentiated and treated without harming the healthy cells. This review discusses the use of nanoparticles like quantum dots and fullerenes for detection of cancer cells by acting as imaging agents. These are crucial for identifying the affected cells and tissues for effective measurement. Liposomes and dendrimers are used in treatment through development of advanced drug delivery systems. Some other nanoparticles like carbon nanotubes and magnetic nanoparticles have extended application in both imaging and treatment. Due to its wide ranging properties and diverse applications, the nanoparticles developed so far and nanotechnology as a whole has a huge potential in cancer treatment

Field-free spin-orbit torque switching of a perpendicular ferromagnet with Dzyaloshinskii-Moriya interaction

Leveraging on interfacial Dzyaloshinskii-Moriya interaction (DMI) induced intrinsic magnetization tilting in nanostructures, a parametric window enabling field-free spin-orbit torque (SOT) magnetization switching in a perpendicular ferromagnet is established. The critical current density (Jc) bounds for SOT switching are highly dependent on the DMI, producing a distorted diamond-shaped region bounded by the Jc-DMI curves. The widest Jc interval is found for DMI values between 0.5 mJ/m2 and 0.8 mJ/m2. Geometrical modulation, of the ferromagnetic layer, reveals that the circular structure is optimum for minimizing the switching energy while maximizing the parametric window. For all the structures investigated, the SOT induced reversal process is via domain wall nucleation and propagation, and the switching is practical at room temperature

Herbal Remedies for Breast Cancer Prevention and Treatment

Breast cancer is among the most common type of cancer in women around the globe. Prevention of breast cancer is better than its treatment. Because of the molecular variation and complexity underlying breast cancer occurrence, its treatment by using chemotherapy and/or radiotherapy is very complicated and often leads to undesirable side effects. Plants and their extracts have been used for centuries for the treatment of almost every disease and breast cancer is not an exception. Herbal products can be trusted for cancer treatment because of their low toxicity. Besides, herbal remedies are easily accepted by the majority of woman suffering from breast cancer because of their easy availability and affordability. In the last decade, a large number of plants and their compounds were reported to show promising anticancerous effects against breast cancer cells in both in vivo and in vitro models. However, their beneficial effects on breast cancer treatment are still doubtful due to the lack of randomized clinical trials. This chapter is dedicated to reporting the potential of some herbal products for the prevention and/or treatment of breast cancer. Besides, it focused on the anticarcinogenic mechanism of those phytocompounds to report their potential chemotherapeutic role

Imaging in Van Wyk Grumbach syndrome: An uncommon presentation of hypothyroidism

Isosexual precocious puberty with ovarian masses in long-standing juvenile hypothyroidism is well described in the literature as Van Wyk Grumbach syndrome (VWGS). The present case reports this rare entity in a 4-year-old girl who was referred for imaging to evaluate the cause of non-traumatic bleeding per vagina. Antecedent history, clinical features and thyroid function tests were consistent with long-standing juvenile hypothyroidism with documented clinical response to thyroxine replacement therapy. Contribution: Typical clinical and radiological features of the syndrome are reported, which helps in the early diagnosis and management, henceforth avoiding the associated complications

Visualizing the strongly reshaped skyrmion Hall effect in multilayer wire devices.

Magnetic skyrmions are nanoscale spin textures touted as next-generation computing elements. When subjected to lateral currents, skyrmions move at considerable speeds. Their topological charge results in an additional transverse deflection known as the skyrmion Hall effect (SkHE). While promising, their dynamic phenomenology with current, skyrmion size, geometric effects and disorder remain to be established. Here we report on the ensemble dynamics of individual skyrmions forming dense arrays in Pt/Co/MgO wires by examining over 20,000 instances of motion across currents and fields. The skyrmion speed reaches 24 m/s in the plastic flow regime and is surprisingly robust to positional and size variations. Meanwhile, the SkHE saturates at ∼22∘, is substantially reshaped by the wire edge, and crucially increases weakly with skyrmion size. Particle model simulations suggest that the SkHE size dependence - contrary to analytical predictions - arises from the interplay of intrinsic and pinning-driven effects. These results establish a robust framework to harness SkHE and achieve high-throughput skyrmion motion in wire devices

Giant magnetoresistance of Dirac plasma in high-mobility graphene

The most recognizable feature of graphene's electronic spectrum is its Dirac point around which interesting phenomena tend to cluster. At low temperatures, the intrinsic behavior in this regime is often obscured by charge inhomogeneity but thermal excitations can overcome the disorder at elevated temperatures and create electron-hole plasma of Dirac fermions. The Dirac plasma has been found to exhibit unusual properties including quantum critical scattering and hydrodynamic flow. However, little is known about the plasma's behavior in magnetic fields. Here we report magnetotransport in this quantum-critical regime. In low fields, the plasma exhibits giant parabolic magnetoresistivity reaching >100% in 0.1 T even at room temperature. This is orders of magnitude higher than magnetoresistivity found in any other system at such temperatures. We show that this behavior is unique to monolayer graphene, being underpinned by its massless spectrum and ultrahigh mobility, despite frequent (Planckian-limit) scattering. With the onset of Landau quantization in a few T, where the electron-hole plasma resides entirely on the zeroth Landau level, giant linear magnetoresistivity emerges. It is nearly independent of temperature and can be suppressed by proximity screening, indicating a many-body origin. Clear parallels with magnetotransport in strange metals and so-called quantum linear magnetoresistance predicted for Weyl metals offer an interesting playground to further explore relevant physics using this well-defined quantum-critical 2D system.Comment: 8 pages, 3 figure

A Real Space Description of Field Induced Melting in the Charge Ordered Manganites: II. the Disordered Case

We study the effect of A site disorder on magnetic field induced melting of charge order (CO) in half doped manganites using a Monte-Carlo technique. Strong A-site disorder destroys CO even without an applied field. At moderate disorder, the zero field CO state survives but has several intriguing features in its field response. Our spatially resolved results track the broadening of the field melting transition due to disorder and explain the unusual dependence of the melting scales on bandwidth and disorder. In combination with our companion paper on field melting of charge order in clean systems we provide an unified understanding of CO melting across all half doped manganites.Comment: 9 pages, pdflatex, 10 embedded png fig
