Utilization of a biosurfactant foam/nanoparticle mixture for treatment of oil pollutants in soil

Author(s): Vu KA; Mulligan CN;

Oil contamination has become a primary environmental concern due to increased exploration, production, and use. When oil enters the soil, it may attach or adsorb to soil particles and stay in the soil for an extended period, contaminating the soil and surrounding areas. Nanoparticles have been widely used for the treatment of organic pollutants in the soi ...

Household income and maternal education in early childhood and risk of overweight and obesity in late childhood: Findings from seven birth cohort studies in six high-income countries

Author(s): White PA; Awad YA; Gauvin L; Spencer NJ; McGrath JJ; Clifford SA; Nikiema B; Yang-Huang J; Goldhaber-Fiebert JD; Markham W; Mensah FK; van Grieken A; Raat H; Jaddoe VWV; Ludvigsson J; Faresjö T;

Background/objectives: This study analysed the relationship between early childhood socioeconomic status (SES) measured by maternal education and household income and the subsequent development of childhood overweight and obesity. Subjects/methods: Data from seven population-representative prosp ...

Invariance, Encodings, and Generalization: Learning Identity Effects With Neural Networks

Author(s): Brugiapaglia S; Liu M; Tupper P;

Often in language and other areas of cognition, whether two components of an object are identical or not determines if it is well formed. We call such constraints identity effects. When developing a system to learn well-formedness from examples, it is easy enough to build in an identity effect. But can identity effects be learned from the data without exp ...

On the Origin of Sugar Handedness: Facts, Hypotheses and Missing Links-A Review

Author(s): Martínez RF; Cuccia LA; Viedma C; Cintas P;

By paraphrasing one of Kipling's most amazing short stories (How the Leopard Got His Spots), this article could be entitled "How Sugars Became Homochiral". Obviously, we have no answer to this still unsolved mystery, and this perspective simply brings recent models, experiments and hypotheses into the homochiral homogeneity of sugars on earth. We shal ...

Effect of oxidative aging of biochar on relative distribution of competitive adsorption mechanism of Cd2+ and Pb2

Author(s): Wang Z; Geng C; Bian Y; Zhang G; Zheng C; An C;

In this study, aged biochar (CCB350 and CCB650) were obtained from pyrolysis of corn stalk biochar (CB350 and CB650) at the degree of 350 °C and 650 °C by artificial oxidation with hydrogen peroxide (H2O2). Also, the mechanism of Pb2+ and Cd2+ on fresh and aged biochars was analyzed qualitatively and quantitatively by batch adsorption experiments combined ...

Exploring the characteristics, performance, and mechanisms of a magnetic-mediated washing fluid for the cleanup of oiled beach sand

Author(s): Yue R; An C; Ye Z; Chen X; Lee K; Zhang K; Wan S; Qu Z;

In the present study, an innovative, environmentally benign recyclable, and magnetically mediated surface washing fluid based on water-dispersible magnetite nanoparticles has been designed and investigated for the cleanup of oiled beach sand. The characterization results showed that the as-prepared magnetite nanoparticles had a spherical morphology with a ...

The effect of phasic versus combined neuromuscular electrical stimulation using the StimaWELL 120MTRS system on multifidus muscle morphology and function in patients with chronic low back pain: a randomized controlled trial protocol

Author(s): Fortin M; Wolfe D; Dover G; Boily M;

Background: Neuromuscular electrical stimulation (NMES) is used to improve muscle strength clinically when rehabilitating various musculoskeletal disorders. However, the effects of NMES on muscle morphology and function in individuals with non-specific chronic low back pain (CLBP) have scarcely been investigated. Although research links deficits in the pa ...

Measures of motor segmentation from rapid isometric force pulses are reliable and differentiate Parkinson's disease from age-related slowing

Author(s): Howard SL; Grenet D; Bellumori M; Knight CA;

Some people with Parkinson's disease (PD) have disruptions in motor output during rapid isometric muscle contractions. Measures of such disruptions (motor segmentation) may help clarify disease subtype, progression, or effects of therapeutic interventions. We investigated the potential utility of segmentation measures by testing two hypotheses that ar ...

Pattern and Visual Prognostic Factors of Behcet's Uveitis in Northwest Iran

Author(s): Alizadeh Ghavidel L; Bagheri M; Mousavi F; Rezaei L; Hazeri S; Hashemi HS;

Purpose: To investigate the pattern of ocular involvement in Behcet's disease (BD) with predictors of patients' final state of vision. Methods: This historical cohort encompassed the clinical records of 200 patients diagnosed according to the International Criteria for BD (ICBD), over a period of 17 years between 2004 and 2021. Results: The prev ...

Improving candidate Biosynthetic Gene Clusters in fungi through reinforcement learning

Author(s): Almeida H; Tsang A; Diallo AB;

Motivation: Precise identification of Biosynthetic Gene Clusters (BGCs) is a challenging task. Performance of BGC discovery tools is limited by their capacity to accurately predict components belonging to candidate BGCs, often overestimating cluster boundaries. To support optimizing the composition and boundaries of candidate BGCs, we pro ...

Population demography maintains biogeographic boundaries

Author(s): Schmidt C; Muñoz G; Lancaster LT; Lessard JP; Marske KA; Marshall KE; Garroway CJ;

Global biodiversity is organised into biogeographic regions that comprise distinct biotas. The contemporary factors maintaining differences in species composition between regions are poorly understood. Given evidence that populations with sufficient genetic variation can adapt to fill new habitats, it is surprising that more homogenisation of species asse ...

Energy, economic, and environmental impacts of enhanced ventilation strategies on railway coaches to reduce Covid-19 contagion risks

Author(s): Barone G; Buonomano A; Forzano C; Giuzio GF; Palombo A;

In the last years, the Covid-19 outbreak raised great awareness about ventilation system performance in confined spaces. Specifically, the heating, ventilation, and air conditioning system design and operating parameters, such as air change per hour, air recirculation ratio, filtration device performance, and vents location, play a crucial role in reducin ...
