Abstract The use of hybrid nanofluids in direct-absorption solar collectors is an efficient approach to harnessing energy. To address current energy challenges, this study new nanoparticle aggregates containing distinct silver-based and iron-oxide nanophases (Ag+Fe2O3) were used improve the photothermal conversion characteristics direct absorption collectors. main goal was investigate effect co...

Knowledge-based strategic planning: harnessing (in)tangible assets of city-regions Structured Abstract Purpose – The aim of this paper is to investigate the ways of best managing city-regions' valuable tangible and intangible assets while pursuing a knowledge-based ...

Poverty alleviation is one of the most difficult challenges facing any country in the developing world, where, on the average, majority of the population is considered poor. Evidences in Nigeria shows that the number of those in poverty has continued to increase and Borno state was acknowledged to be at the forefront. Governments and institutions have the capacity to enhance both the viability ...

769 Humans have long been fascinated by the dynamism of free-flowing waters. Yet we have expended great effort to tame rivers for transportation, water supply, flood control, agriculture, and power generation. It is now recognized that harnessing of streams and rivers comes at great cost: Many rivers no longer support socially valued native species or sustain healthy ecosystems that provide imp...

Endophytic microorganisms exist within the living tissues of most plant species. They are most abundant in rainforest plants. Novel endophytes usually have associated with them novel secondary natural products and/or processes. Muscodor is a novel endophytic fungal genus that produces bioactive volatile organic compounds (VOCs). This fungus, as well as its VOCs, has enormous potential for uses ...

Several machine learning models, including neural networks, consistently misclassify adversarial examples—inputs formed by applying small but intentionally worst-case perturbations to examples from the dataset, such that the perturbed input results in the model outputting an incorrect answer with high confidence. Early attempts at explaining this phenomenon focused on nonlinearity and overfitti...

Non-collinear spin transport is at the heart of spin or magnetization control in spintronics devices. The use of nanoscale conductors exhibiting quantum effects in transport could provide new paths for that purpose. Here we study non-collinear spin transport in a quantum dot. We use a device made out of a single-wall carbon nanotube connected to orthogonal ferromagnetic electrodes. In the spin ...

In the field of offshore renewable energy, impermeable plates are used as underwater lenses to amplify wave amplitude, and perforated can harness energy a power takeoff device. Within framework linear potential-flow theory, water scattering by horizontal is investigated in present study, both circular elliptical considered. The hypersingular integral equation constructed model interaction betwe...

Whereaswater drops on both lotus leafs and rose petals have high contact angles, the drops can easily roll off lotus leafs but strongly adhere to rose petals. Here, we report a simple and cost-effective approach to fabricate highly stretchable large-area surfaces that give lotusleaf and rose-petal effects by harnessing origami patterns formed in graphene paper (GP) bonded on a pre-strained elas...

Two viral proteins, HIV-1 protease and HIV-1 integrase, have been targeted for inhibitor design to prevent assembly and maturation of HIV-1 virions. The enzymatic mechanism of these proteins involves side-chain groups that serve as general acids or bases. Furthermore, catalytic activity requires that water be removed from the microenvironment surrounding the chemical reaction site or be constra...
