Polycrystalline diamond (PCD) is widely applied in the cutting and drilling industry due to its excellent mechanical properties. Currently, several researchers have been studying the use of different binders in its manufacturing, seeking to improve its properties and reduce the use of traditional metals that are harmful to human health and the environment. This work aims to study the viability of tantalum as an alternative binding agent for PCD. The products developed were processed using powder ...

The objective of this research was to obtain a triple layer Polycrystalline Diamond Compact (PDC) via the High-pressure High-temperature (HPHT) sintering method. A thin layer of WC with 20 wt% Nb/Ni was used as an interface between the top layer of Polycrystalline Diamond (PCD) with pure Nb binder and WC 10 wt% Co substrate. Sintering was performed at 1750 °C under 7.7 GPa of pressure. Microhardness variation was measured and microstructural/structural studies were done via SEM/EDS and XRD. The overall ...

Monoterpenes are one of the most studied plant's secondary metabolites, they are found abundantly in essential oils of aromatic plants. They also have a great range of pharmacological properties, such as antihypertensive, bradycardic, antiarrhythmic and hypotensive. In the face of the burden caused by cardiovascular disease (CVDs) worldwide, studies using monoterpenes to assess their cardiovascular effects have increased over the years.This systematic review aimed to summarize the use of monoterpenes ...

Frost, extreme high temperatures, dry spells, and other weather extremes influence crop development, often causing major variations in yield from one season to the next. Selected growth stages such as flowering and grain filling are particularly sensitive to temperature and/or precipitation extremes and farmers are often unable to manage this risk. Crop simulation models have matured into powerful tools for identifying strategies in fully utilizing scarce natural resources under variable climate ...

Abstract Benzene is a widespread volatile compound and an environmental contaminant. Since it causes important toxic effects in workers exposed to low levels, long‐term exposure to this compound has been extensively studied. Leukemia, blood disorders, bone marrow depression, and some types of cancer are directly related to benzene‐initiated toxicity. Bioactivation of benzene can lead to the formation of hazardous metabolites such as phenol, hydroquinone, and catechol. Catechol forms semiquinones ...

Abstract Perinatal asphyxia remains as one of the most important causes of death and disability in children, without an effective treatment. Moreover, little is known about the long‐lasting behavioral consequences of asphyxia at birth. Therefore, the main aim of the present study was to investigate the motor, emotional and cognitive functions of adult asphyctic rats. Experimental subjects consisted of rats born vaginally (CTL), by cesarean section (C+), or by cesarean section following 19 min of asphyxia ( ...

The discharge of synthetic dyes from different industrial sources has become a global issue of concern. Enormous amounts are released into wastewater each year, causing concerns due to the high toxic consequences. Photocatalytic semiconductors appear as a green and sustainable form of remediation. Among them, graphitic carbon nitride (g-C3N4) has been widely studied due to its low cost and ease of fabrication. In this work, the synthesis, characterization, and photocatalytic study over methylene ...

In Brazil, municipal solid waste management (MSWM) faces several challenges in its transition from a waste disposal model to another based on selective collection with recycling and reuse. Each municipality has adopted different institutional arrangements to meet the responsibility shared by the State, industries, and consumers to operate public policies in this field. The consequence has been an inefficient recycling rate, high costs, and the exclusion of waste collectors from the official system. ...

Perinatal asphyxia (PA) is a medical condition associated with a high short-term morbimortality and different long-term neurological diseases. In previous works, we have shown that neuronal and synaptic changes in rat striatum lead to ubi-protein accumulation in post-synaptic density (PSD) after six months of sub-severe PA. However, very little is known about the synaptic and related structural modifications induced by PA in young rats. In the present work, we studied neuronal cytoskeleton modifications ...

Synaptic dysfunction has been associated with neuronal cell death following hypoxia. The lack of knowledge on the mechanisms underlying this dysfunction prompted us to investigate the morphological changes in the postsynaptic densities (PSDs) induced by hypoxia. The results presented here demonstrate that PSDs of the rat neostriatum are highly modified and ubiquitinated 6 months after induction of hypoxia in a model of perinatal asphyxia. Using both two dimensional (2D) and three dimensional (3D) electron ...

Astrocytes are the most abundant cells of the central nervous system; they have a predominant role in maintaining brain metabolism. In this sense, abnormal metabolic states have been found in different neuropathological diseases.

Thus, genome-scale metabolic networks derived from transcriptomic data can be used as a framework to elucidate ...

Neurodegeneration in Parkinson's disease appears to be caused by multiple factors, including oxidative damage and an increase in acetylcholinesterase expression that can culminate in loss of dopaminergic neurons. A selenium-containing quinoline derivative, 7-chloro-4-(phenylselanyl) quinoline (4-PSQ), shows important pharmacological actions mainly attributed to its antioxidant and anticholinesterase properties. Thus, this study investigated the neuroprotective effect of 4-PSQ in a model of Parkinson' ...
