    A água é um nutriente às vezes subestimado. Os animais geralmente têm acesso a muita água e não nos preocupamos muito em fornecê-la. Todavia, quando colocamos animais em alojamentos intensivos, ou fontes naturais de água que secam durante as secas ou por qualquer outro motivo, então a importância da água e as consequências da falta dela imediatamente tornam-se óbvias. Nesse sentido, o livro aborda tópicos importantes e atualizados sobre a importância da água e dos requerimentos da mesma para os animais (...)

  4. Recovery of precious metals from e-wastes through conventional and phytoremediation treatment methods: a review and prediction. [REVIEW]Chuck Chuan Ng - 2023 - Journal of Material Cycles and Waste Management 2023.
    E-waste, also known as waste from electrical and electronic equipment, is a solid waste that accumulates quickly due to high demand driven by the market for replacing newer electrical and electronic products. The global e-waste generation is estimated to be between 53.6 million tons, and it is increasing by 3–5% per year. Metals make-up approximately 30% of e-waste, which contains precious elements Au, Ag, Cu, Pt, and other high-value elements, valued at USD 57 billion, which is driving the e-waste recycling (...)

  5. Roles and significance of chelating agents for potentially toxic elements (PTEs) phytoremediation in soil: A review. [REVIEW]Chuck Chuan Ng - 2023 - Journal of Environmental Management 341 (117926).
    Phytoremediation is a biological remediation technique known for low-cost technology and environmentally friendly approach, which employs plants to extract, stabilise, and transform various compounds, such as potentially toxic elements (PTEs), in the soil or water. Recent developments in utilising chelating agents soil remediation have led to a renewed interest in chelate-induced phytoremediation. This review article summarises the roles of various chelating agents and the mechanisms of chelate-induced phytoremediation. This paper also discusses the recent findings on the impacts of chelating agents (...)

    Plastic waste is a significant environmental problem for almost all countries; therefore, protecting the environment from the problem is crucial. The most sensible solution to these problems is substituting the natural aggregates with substantial plastic waste in various building materials. This study aimed to optimise the mixed design ratio of cement brick containing plastic waste as aggregate replacement. Plastic cement brick mixtures were prepared by the incorporation of four different types of plastic waste such as polyethylene terephthalate (PET), high-density polyethylene, (...)

    E-waste is one of the most pressing challenges of our time, yet it is often ignored, especially in Southeast Asia. The “tsunami of e-waste” in the region has been putting our lives and our environment at risk. With the extensive use of electrical and electronic devices, we are also contributing to harming the environment and quickening the climate change by producing and discarding e-waste. Youths are among major users of electronic devices, and hunger for upgraded and newer versions. -/- However, (...)

    In this paper, we try to understand how Bunge’s scientific hylorealism can fit with several crystal chemistry’s objects and their properties. It is found that many of them, lying at the very core of this discipline, bring support to ontologi-cal emergentism. Building units, such as vacancies, their chemical potential, the crystal quantum number and many aspects of the spectroscopic properties of 4f electrons in ionic crystals, are presented as striking examples of emergent (or submergent) objects or properties encountered in the (...)

    The environmental concern of plastic waste (PW) generation has escalated to an alarming level due to the versatility and high demand in various applications. In order to search for an effective way to utilise PW, reusing them for the production of construction material appears as an environmentally-friendly approach. This is also because conventional construction materials often consume high energy during production has caused many environmental impacts. This review paper summarises the previous studies on reusing various PW as raw material and (...)

  21. Phytoassessment of Vetiver grass enhanced with EDTA soil amendment grown in single and mixed heavy metal–contaminated soil.Chuck Chuan Ng - 2019 - Environmental Monitoring and Assessment 191 (434):1-16.
    Over the years, ethylene-diamine-tetra-acetate (EDTA) has been widely used for many purposes. However, there are inadequate phytoassessment studies conducted using EDTA in Vetiver grass. Hence, this study evaluates the phytoassessment (growth performance, accumulation trends, and proficiency of metal uptake) of Vetiver grass, Vetiveria zizanioides (Linn.) Nash in both single and mixed heavy metal (Cd, Pb, Cu, and Zn)—disodium EDTA-enhanced contaminated soil. The plant growth, metal accumulation, and overall efficiency of metal uptake by different plant parts (lower root, upper root, lower (...)

    The Adverse Outcome Pathway (AOP) concept is a knowledge assembly and communication tool to facilitate the transparent translation of mechanistic information into outcomes meaningful to the regulatory assessment of chemicals. The AOP framework and associated knowledgebases (KBs) have received significant attention and use in the regulatory toxicology community. However, it is increasingly apparent that the potential stakeholder community for the AOP concept and AOP KBs is broader than scientists and regulators directly involved in chemical safety assessment. In this paper we (...)

    Philosophical discussion about the reality of sensory perceptions has been hijacked by two tendencies. First, talk about perception has been largely centered on vision. Second, the realism question is traditionally approached by attaching objects or material structures to matching contents of sensory perceptions. These tendencies have resulted in an argumentative impasse between realists and anti-realists, discussing the reliability of means by which the supposed causal information transfer from object to perceiver takes place. Concerning the nature of sensory experiences and their (...)

This paper considers Bird's (2001, 2002, 2005, 2007) arguments for the thesis that, necessarily, salt dissolves in water; and it defends his view against Beebee's (2001) and Psillos's (2002) contingentist objections. A new contingentist objection is offered and several reasons for scepticism about its success are raised. It is concluded that (...)

    At the heart of chemistry lies the periodic system of chemical elements. Despite being the cornerstone of modern chemistry, the overall structure of the periodic system has never been fully understood from an atomic physics point of view. Group-theoretical models have been proposed instead, but they suffer from several limitations. Among others, the identification of the correct symmetry group and its decomposition into subgroups has remained a problem to this day. In an effort to deepen our limited understanding of the (...)

    Chemistry and physics are two sciences that are hard to connect. Yet there is significant overlap in their aims, methods, and theoretical approaches. In this book, the reduction of chemistry to physics is defended from the viewpoint of a naturalised Nagelian reduction, which is based on a close reading of Nagel's original text. This naturalised notion of reduction is capable of characterising the inter-theory relationships between theories of chemistry and theories of physics. The reconsideration of reduction also leads to a (...)

Results were compared with those of "enhanced pair flipping" (EPF), a more elaborate problem-specific algorithm incorporating local and global searches. Not surprisingly, EPF did better than the GA or SA approaches, but the existence of GA and SA techniques more advanced than those used in this study suggest that these techniques still hold (...)
