Abstract: Ecology has always been an essential topic in literature. However, with the arrival of the Anthropocene, our society is beginning to seriously rethink of the relationship between human and nature. Literature can contribute both to generating ecological awareness and to compensating for imminent losses of flora and fauna. Not only can it re-narrate the stories of those species that face the greatest challenges; it can also encourage environmental orientation about future coexistence by expanding the imagination of the possible. Sigrid Nunez’s) What Are You Going Through( )2020) presents a universe that is supposedly unaffected by birds or plants, but in which a connectedness between living beings is explored that cannot

Optical losses represent one of the primary obstacles to increasing the efficiency of silicon solar cells. The recommended solution to minimize optical losses is the use of plasmonic metal nanoparticles; however, they act as recombination centers within the solar cell construction, leading to a decrease in performance. The goal of this article is to introduce cobalt/graphene nanoparticles into the solar cell to minimize the optical losses. An ultra-thin film silicon PIN solar cell of dimensions (400 ×400 ×900) nm3 with ring metal contact shape was designed and numerically investigated using COMSOL Multiphysics software version 6.2 by the finite element method (FEM). Core/shell cobalt-graphene (Co/Gr) nanoparticles are periodically int

After performing analysis of statistical, it was set up that the correlation coefficient of the PCR technique using virulence genes, sensitivity test to antibiotics and other virulence factors were significant at p < 0.05, but was insignificant with the

In the present work, the image and representation of Adela, the youngest daughter of the family of the Casa de Bernarda Alba, one of the most popular works of the Spanish author Federico García Lorca (1898-1936), will be analyzed. In this work, there are different themes, but what concerns us is to show the repression, oppression and rebellion of this character in a context of customs of the 1920s in Spain. They are revealing elements in that period in which women were relegated to the background, despite the fact that a feminist movement had already begun in Spain. By studying Adela, we seek to see how a single woman confronts her family and the society that surrounds her to fight for freedom, although its end is finally linked to

The interactions of drug amoxicillin with maltose or galactose solutions with a variation of temperature have been discussed by taking in the volumetric and viscometric procedures. Physical properties [densities (ρ) and viscosities (η)] of amoxicillin (AMOX) aqueous solutions and aqueous solutions of two type saccharides (maltose and galactose 0.05m) have been measured at T = (298.15, 303.15 and 308.15) K under atmospheric pressure. The apparent molar volume (ϕv cm3mole-1) has been evaluated from density data and fitted to a Redlich-Mayer equation. The empirical parameters of the Mayer-Redlich equation and apparent molar volume at infinite dilution Ø°v were explicated in terms of interactions from type solute-solvent and solute

كان للتنظيمات الإرهابية دور كبير في إبادة التراث الثقافي في العراق، ونخص بالدراسة عصابات داعش الإرهابية، ففي يونيو / حزيران 2014م، شنت عصابات داعش الإرهابية حرباً شرسة، هاجمت تقريباً الطوائف العرقية والدينية جميعها، في خضم ذلك، استهدفت مواقع التراث الثقافي. إن تدمير العصابات الإرهابية للتراث الثقافي ليس نتيجة جانبية للعنف، بل كان تدخل مخطط وموثق بعناية. في الواقع، إن الإبادة الثقافية التي ارتكبها مجرمو داع

A research was conducted to determine the feasibility of using adsorption process to remove boron from aqueous solutions using batch technique. Three adsorbent materials; magnesium, aluminum and iron oxide were investigated to find their abilities for boron removal. The effects of operational parameters on boron removal efficiency for each material were determined.
The experimental results revealed that maximum boron removal was achieved at pH 9.5 for magnesium oxide and 8 for aluminum and iron oxide. The percentage of boron adsorbed onto magnesium,aluminum and iron oxide reaches up to 90, 42.5 and 41.5% respectively under appropriate conditions. Boron concentration in effluent water after adsorption via magnesium oxide comply with th

An analysis was performed on the treated water from two water treatment plants in Baghdad
city. This analysis was used to evaluate the stability of the treated water from these plants and
that will flow in the distribution system to consider its corrosivity. The variation in water
stability with time and distance from the north to the south of Baghdad was indicated. The
analysis showed that the flowing water in the distribution system in Baghdad is corrosive to very
corrosive water by calculating Ryznar stability index (RI). In Al- Karkh WTP in the north, RI
maximum ranged between 7.958 to 9.403 where RI minimum ranged between 7.03 to 7.915.

The present work considers an alternative solution for a complex configuration of rotor discs by applying Galerkin Method. The theoretical model consists of elastic shaft carrying number of discs and supported on number of journal bearings. The equation of motion was discretized to finite degree of freedom in terms of the system generalized coordinates. The various effects of the dynamical forces and moments arising from the bearing, discs and shaft were included. Rayleigh beam model is used for analyzing the shaft while the discs are considered rigid . The validity and convergence of the present analysis was carefully checked by comparing with the Finite Element solution. An example of rotor consists of three different size discs and su

The present work reports on the performance of three types of nanofiltration membranes in the removal of highly polluting and toxic lead (Pb²⁺) and cadmium (Cd²⁺) from single and binary salt aqueous solutions simulating real wastewaters. The effect of the operating variables (pH (5.5-6.5), types of NF membrane and initial ions concentration (10-250 ppm)) on the separation process and water flux was investigated. It was observed that the rejection efficiency increased with increasing pH of solution and decreasing the initial metal ions concentrations. While the flux decreased with increasing pH of solution and increasing initial metal ions concentrations. The maximum rejection of lead and cadmium ion
