Skin wounds are frequently influenced with microbial infections and inflammation, which need innovative agents for disputing them. Chitosan (Csn) was extracted from larvae of BSF “black soldier fly, Hermetia illucens” ethanolic propolis extract (Pro) employed synthesizing silver nanoparticles (Ag-NPs), using facile biogenic protocol. The BSF-Csn acquired a yield 1.56%, 91.3% deacetylation degre...

Recycled aggregate concrete (RAC) technology is broadly adopted in the construction industry. However, such tends to promisingly be implemented only countries with developed economies, leaving behind emerging economies. To increase utilization of RAC these economy countries, this research program aims investigate applicability using artificial neural network (ANN) technique predict onsite activ...

Celestial holography promisingly reformulates the scattering amplitude holographically in terms of celestial conformal field theory living at null infinity. Recently, an infinite-dimensional symmetry algebra was discovered Einstein-Yang-Mills theory. The starting point derivation is OPE two soft currents, and key ingredient summation $\overline{SL(2,\mathbb R)}$ descendants OPE. In this paper, ...

the purpose of this study was to identify daily changes in body weight of broiler chickens using image processing and multi-regression analysis. therefore, thirty 1-day-old broiler chickens were reared under standard rearing condition and after acquiring images they were weighted, individually. from 2490 digital images, six features (perimeter, area convex, major axis, minor axis, eccentricity)...

The genus Centaurea with an extensive background in Iranian traditional medicine represents more than 70 species in Iran that some of them are endemic to Iran. A variety of secondary metabolites has been isolated from this genus thus far. Sesquiterpene lactones and flavonoids have been reported as main compounds of C.bruguierana. Methanolic extract and different fractions of the whole fruiting ...

Abelmoschus esculentus L. (ladies finger, okra) is a well-known tropical vegetable, widely planted from Africa to Asia and from South Europe to America. In the present study, we investigated the in vitro antioxidant capacity and in vivo protective effect of the aqueous and methanolic seed extracts of Abelmoschus esculentus against scopolamine-induced cognitive impairment using passive avoidance...

Oleanolic acid is a poorly water-soluble drug with low oral bioavailability. A self-microemulsifying drug delivery system (SMEDDS) has been developed to enhance the solubility and oral bioavailability of oleanolic acid. The formulation design was optimized by solubility assay, compatibility tests, and pseudoternary phase diagrams. The morphology, droplet size distribution, zeta potential, visco...

Since approval of the use of the excimer laser in 1995 to reshape the cornea, significant developments in the correction of refractive errors such as myopia, hyperopia, and astigmatism have been achieved. Combined with other advanced ophthalmological instruments (e.g. anterior segment imaging systems, the femtosecond laser, wavefront-guided customized ablation) and the knowledge accumulated con...

BACKGROUND Propensity score methods have become a popular tool for reducing selection bias in making causal inference from observational studies in medical research. Propensity score matching, a key component of propensity score methods, normally matches units based on the distance between point estimates of the propensity scores. The problem with this technique is that it is difficult to estab...

The fast growth of the cyberspace in recent years has served as a convenient channel for criminals to do their illegal businesses, especially in Dark Web the hidden side of the Internet. The anonymous nature of Dark Web forums makes them ideal environments for criminal discussions. Ranging from government, security agencies to financial institutions, many parties are willing to trace the identi...
