Abstract:
... The main factor influencing tool life in particleboard machining is mineral content, and therefore the aim of this investigation is to study the issue and evaluate the tool lifetime by machining different particleboards Also, the change of the mineral content of particle boards over a time frame of 30 years and the geographic origin of the boards should also be taken in account. For this purpose, ...

Abstract:
... Time‐of‐flight secondary ion mass spectrometry (TOF‐SIMS) imaging is a surface analysis technique that identifies and spatially resolves the chemical composition of a sample with a lateral resolution of less than 1 μm. Depth analyses can also be performed over thicknesses of several microns. In the case of a painting cross section, for example, TOF‐SIMS can identify the organic composition, by det ...

Abstract:
... Although the element composition of raw propolis gets more and more attention, their products, like tincture are barely analyzed. In this study the element content of tinctures prepared by 80% (v/v) ethanol is measured parallel to the initial raw propolis. Most of the essential elements had relatively high transfer coefficients to the tincture in the range of 14.2–67.3% by median. In contrast, mos ...

Abstract:
... Microtextures of quartz sand grains can be used to establish sedimentary provenance of sedimentary deposits. V-shaped percussion cracks (Vs), which are randomly produced by grain-to-grain mechanical collision in high-energy subaqueous environments, are significant microtextures used for investigation of fluvial and marine sediment. In previous studies, others have used the percentage of microtextu ...

Abstract:
... Melon cracking is a physiopathy that is associated with both internal and external changes by the alteration of the water balance and nutrient homeostasis in the fruit. Aquaporins are channels for water and other small solutes, and they are potentially involved in the regulation of melon cracking. In this work, we studied the mineral concentration and expression of all aquaporins in non-cracked an ...

Abstract:
... Although numerous studies have determined significant contamination in terms of trace organic contaminant (TrOC) diversity and concentration, the occurrence of TrOCs within solid matrices as suspended solids and sediments flies under the radar. In this study, the occurrence of 35 TrOCs of various classes (i.e. pharmaceutical products and pesticides) was investigated in three compartments, namely d ...

Abstract:
... In this study, mineral composition, centesimal composition and lead were evaluated in pine nut seeds (raw and cooked) from five Brazilian states. Mineral composition was determined by ICP OES and lead by GF AAS. The results for minerals were evaluated by Boxplot, PCA and HCA, using the R software. Average minerals in raw and cooked samples (mg 100 g⁻¹) were: 15.2 and 10.8 (Ca), 0.168 and 0.113 (Cu ...

Abstract:
... Studies on the mineral content of different rosehip species/cultivars during the ripening period are very limited. Therefore, the objective of this research was to evaluate the content and composition of the mineral elements of two species and two rosehip cultivars growing on an organic farm. The rosehip fruits were harvested at different ripening stages, five time per season. Mineral composition ...

Abstract:
... The studied limestone is a well known Portuguese natural stone that occurs in Valverde—Alcanede region, located in the Maciço Calcário Estremenho (center of Portugal). This stone is used in several exterior and interior applications such as paving, cladding, masonry and decorations. Slabs made of the studied limestone were installed in ventilated facade with a “kerf” anchoring system in a building ...

Abstract:
... BACKGROUND: Zanthoxylum bungeanum pericarps (ZBP) are commonly used as food additives and traditional herbal medicines. Several mineral elements are known to have important physiological functions in organisms, whereas others are reported to have toxic effects. We determined levels of macro elements (Mg, S and Ca), essential trace elements (B, Mn, Fe, Cu, Zn, Se and Mo) and toxic elements (Ni, Al, ...

Abstract:
... PM₁₀ and PM₂.₅ were measured at a suburban coastal Mediterranean site. Daily mass concentrations were generally lower than the WHO air quality limits but showed significant diurnal and seasonal variations, with intensive African dust events and residential heating emissions during wintertime causing the higher % increase of ambient concentrations (32% and 59% respectively). However, analysis of th ...

Abstract:
... The grading evaluation of shales helps in understanding the shale reservoir formation and sweet-spot screening of physical properties. Reservoir formation of shale is closely related to the size, distribution, and connectivity of shale pore–throats. Therefore, characterization and classification of microscopic pore–throats are the basis for shale reservoir grading. However, previous microscopic po ...
