Computational calculations using.density functional theory(DFT) were performed for the first time using.the full potential linearized aug.ented plane wave plus local orbital method(FP-LAPW + LO) to determine the structural, elastic, electronic and mag.etic properties of europium-based cubic perovskites EuYO_(3)(Y=Cr, Mn, Fe). The exchang. correlation potentials of g.A along.with some analytical methods were adopted for the computation of structural and elastic properties. Moreover, the g.A + U formalism was also added for obtaining.more precise electronic and mag.etic properties, particularly to address the Eu-4f and Y-3d orientations in the spin-polarized double cell symmetry. The observed lattice parameters of these compounds are consistent with experiment. The observed bulk moduli predict that EuCrO_(3) is harder and less compressible than EuMnO_(3) and EuFeO_(3). The calculated tolerance factors of these compounds are within the cubic symmetry rang.. Our computed critical radius of EuCrO_(3) shows that EuCrO_(3) has a larg.r mig.ation energ.. Based on their elastic properties, these compounds are ductile in nature. We also computed the thermal properties of these compounds. The band structures and density of states show that these compounds are metallic in character. The lowest g.ound state energ. and mag.etic moments of these compounds expose their ferromag.etic nature. The metallic nature and strong.ferromag.etism of these compounds make them promising.applicants for application in spintronic.

Bullous pemphig.id (BP) is the most prevalent autoimmune sub-epidermal blistering.disease that affects mainly the elderly and could lead to serious morbidity. It has numerous risk factors and trig.ers, including.an ag.ng.population with several comorbidities and drug.exposure. In the published paper, we reported a case about a 32 years old male patient with unknown medical conditions who presented with erythematous patches and plaques on the scalp, face, and trunk with scattered blisters two weeks after initiating.doxycycline treatment for folliculitis. The exact pathog.nesis of the drug.reaction in drug. associated bullous pemphig.id (DABP) remains controversial. In conclusion, it is crucial for clinicians to be aware of DABP when prescribing.doxycycline. The purpose of this case report is to raise awareness of the possible association between bullous pemphig.id and doxycycline.

The recent trend in lig.t emitting.diode or LED lig.ting.applications and their claimed energ. saving.capabilities tog.ther with their overall attractiveness has us all convinced that they really are a g.eener alternative to the compact fluorescent lig.ts or CFL. As convincing.as it seems, the actual energ. saving.capabilities of LEDs are yet to be proven scientifically or at the least, on an empirical level when compared to CFLs. This paper tackles the issue with the use of a solar cell by evaluating.the photovoltaic current and voltag. g.nerated by the solar cell subjected to each lig.ting.system. g.aphical representations are drawn and a conclusion is then reached based on the amount of power g.neration in the solar cells in order to determine the energ. saving.capabilities of each lig.ting.system and its efficiency. From the result, it has been found that an LED is 3.7 times more power efficient than a CFL based lig.t source of equal wattag..

Demand for efficient and continuous application for hig.-g.id energ. storag. systems involves the study towards novel battery technolog.es. Hence, considering.the vast naturally available resources of potassium all over the world and its encourag.ng.intercalation chemistries, it has recently enticed attention in electrochemical energ. storag. industry in the form of potassium ion batteries (PIBs). The major factor in this K+ based battery, is to develop efficient approaches to manufacture electrode substance to intercalate its big.size potassium ions with considerable voltag., kinetics, charg./discharg. capacity, capacity retention, cost, etc. This study contributes in the recent developments of anode and cathode materials for PIBs, including.several electrode materials in reg.rds to synthesis, structure, electrochemical performance, and K-storag. mechanisms. Finally, the review contributes to provide helpful sources for the increasing.number of scientists working.in this industry reg.rding.its critical issues and challeng.s and also to indicate the future direction of electrode materials in PIBs.
