Magnesium gluconate is an organometallic pharmaceutical/nutraceutical used for the prevention and treatment of various diseases caused by the low level of magnesium. The aim of the present study was to investigate the influence of The Trivedi Effect® - Energy of Consciousness Healing Treatment (Biofield Energy Healing) on the physicochemical, thermal, structural, and behavioral properties of magnesium gluconate using powder PXRD, PSD, FT-IR, UV-visible, TGA, and DSC analysis. Magnesium gluconate was divided into two parts - one part was denoted as the control, while the another part was treated with The Trivedi Effect® remotely by eighteen renowned Biofield Energy Healers and defined as the Trivedi Effect® Treated sample. The PXRD analysis exhibited the significant alteration of the crystal morphology of the treated sample compared with the control sample. The crystallite size of the treated sample was significantly altered from -39.99% to 62.57% compared with the control sample. The average crystallite size of the treated sample was decreased by 9.71% compared with the control sample. Particle size of the treated sample at d10, d50, and d90 value was significantly increased by 5.36%, 23.10% and 11.11%, respectively compared with the control sample. The surface area of the treated sample was significantly decreased by 9.76% compared to the control sample. The FT-IR and UV-vis analysis showed that the structural characteristic of the magnesium gluconate remained same in the treated sample compared with control sample. The TGA data revealed that the weight loss of the treated sample in the first and third steps of degradation was increased by 31.58% and 5.94%, respectively, whereas in the second step of degradation, the weight loss was decreased by 7.57% compared with the control sample. The DSC analysis showed that the melting point of the control and treated samples were at 170.29°C and 169.76°C, respectively. The latent heat of fusion of the treated sample was increased by 4.18% compared with the control sample. The current study evaluated that The Trivedi Effect® - Energy of Consciousness Healing Treatment might lead to a new polymorphic form of the magnesium gluconate, which could be more soluble, powder flowability and long-term storage stability compared with the control sample. Hence, the Trivedi Effect® Treated magnesium gluconate would be very useful to design better nutraceutical and/or pharmaceutical formulations that might provide better therapeutic response against inflammatory diseases, immunological disorders, and other chronic infections.

Measurement of electrical resistivity in the magnesium titanate spinel system Mg_2-xTi^y+_1+xO₄, give rise to three types of electrical resistivity behaviour, in the composition range y=+3.25 (x=0.6) to y=+3.333 (x=0.5): (I) From room temperature to 100K a rapid non-linear increase in resistivity occurs with decreasing temperature. (II) Below 100K the resistivity decreases linearly with temperature. (III) For some samples below 50K a transition to zero resistance was observed. Type III behaviour was the most interesting, since there is, as yet, no conclusive evidence for the occurrence of superconductivity in the magnesium titanate spinel system. The zero resistance behaviour was very sensitive to composition and sample history, making reproducibility difficult. Powder x-ray diffraction patterns showed the spinel phase to contain a small amount of a second phase, with an x-ray diffraction pattern similar to MgTiO₃, which has the ilmenite structure. Care in sample preparation increased phase purity but, did not lead to better reproducibility of the zero resistance behaviour. In addition, the zero resistance only lasted a few hours to a few days. The presence of low resistance, in some samples, and the apparent zero resistance is due to the overlap of the <I>3d </I>energy levels of the titanium ions, which reside on the octahedral sites. Doping of the magnesium titanate spinels with M³⁺ cations, in an effort to increase the stability of the zero resistance behaviour, proved to be unsuccessful. Substitution of M³⁺ ions onto the octahedral sites appears to interfere with the overlap of the <I>3d</I> energy levels of the titanium ions causing an increase in electrical resistivity. The deterioration of the zero resistance, with time, appears to be catalysed by air and moisture. Keeping the samples in dry, vacuum conditions allowed critical current behaviour to be measured in one sample. Magnetic susceptibility measurements showed no diamagnetic signal, which is necessary, along with the zero resistance and critical current measurements, to prove the existence of superconductivity.

This research was conducted to advance the knowledge and understanding of the fire performance of light gauge steel frame wall systems through thermal property tests, full-scale fire tests of magnesium oxide board lined walls, 3-D uncoupled and coupled thermal-structural finite element analyses and design of walls with both unstiffened and web-stiffened channel stud sections. It has provided experimental and numerical data and improved finite element strategies and design methods to undertake structural fire design of light gauge steel frame wall systems.

During my PhD I focused my work on the investigation of MgO/SiO2 cements. In the last decades, research on cement formulations alternative to traditional Portland cement has progressively grown, both with the aim of reducing the environmental impact due to the CO2 emissions associated with its production and in view of solving specific needs in particular fields of application. Formulations based on reactive periclase (MgO) and silica (SiO2) in the presence of water hydrate and form a binder phase, M-S-H (magnesium silicate hydrate), analogue to calcium silicate hydrate, C-S-H, present in traditional cements. In spite of its potential importance, there is still little knowledge about its structural features and formulation design. I focused my PhD on this class of cement, aiming to extent the knowledge on this material, which could pave the way for tailoring its macroscopic properties by means of a bottom-up approach, and a multi-technique approach has been used to accomplish this purpose.

Bones are multifunctional passive organs of movement that supports soft tissue and directly attached muscles. They also protect internal organs and are a reserve of calcium, phosphorus and magnesium. Each bone is covered with periosteum, and the adjacent bone surfaces are covered by articular cartilage. Histologically, the bone is an organ composed of many different tissues. The main component is bone tissue (cortical and spongy) composed of a set of bone cells and intercellular substance (mineral and organic), it also contains fat, hematopoietic (bone marrow) and cartilaginous tissue. Bones are a tissue that even in adult life retains the ability to change shape and structure depending on changes in their mechanical and hormonal environment, as well as self-renewal and repair capabilities. This process is called bone turnover. The basic processes of bone turnover are: • bone modeling (incessantly changes in bone shape during individual growth) following resorption and tissue formation at various locations (e.g. bone marrow formation) to increase mass and skeletal morphology. This process occurs in the bones of growing individuals and stops after reaching puberty • bone remodeling (processes involve in maintaining bone tissue by resorbing and replacing old bone tissue with new tissue in the same place, e.g. repairing micro fractures). It is a process involving the removal and internal remodeling of existing bone and is responsible for maintaining tissue mass and architecture of mature bones. Bone turnover is regulated by two types of transformation: • osteoclastogenesis, i.e. formation of cells responsible for bone resorption • osteoblastogenesis, i.e. formation of cells responsible for bone formation (bone matrix synthesis and mineralization) Bone maturity can be defined as the completion of basic structural development and mineralization leading to maximum mass and optimal mechanical strength. The highest rate of increase in pig bone mass is observed in the first twelve weeks after birth. This period of growth is considered crucial for optimizing the growth of the skeleton of pigs, because the degree of bone mineralization in later life stages (adulthood) depends largely on the amount of bone minerals accumulated in the early stages of their growth. The development of the technique allows to determine the condition of the skeletal system (or individual bones) in living animals by methods used in human medicine, or after their slaughter. For in vivo determination of bone properties, Abstract 10 double energy X-ray absorptiometry or computed tomography scanning techniques are used. Both methods allow the quantification of mineral content and bone mineral density. The most important property from a practical point of view is the bone’s bending strength, which is directly determined by the maximum bending force. The most important factors affecting bone strength are: • age (growth period), • gender and the associated hormonal balance, • genotype and modification of genes responsible for bone growth • chemical composition of the body (protein and fat content, and the proportion between these components), • physical activity and related bone load, • nutritional factors: – protein intake influencing synthesis of organic matrix of bone, – content of minerals in the feed (CA, P, Zn, Ca/P, Mg, Mn, Na, Cl, K, Cu ratio) influencing synthesis of the inorganic matrix of bone, – mineral/protein ratio in the diet (Ca/protein, P/protein, Zn/protein) – feed energy concentration, – energy source (content of saturated fatty acids - SFA, content of polyun saturated fatty acids - PUFA, in particular ALA, EPA, DPA, DHA), – feed additives, in particular: enzymes (e.g. phytase releasing of minerals bounded in phytin complexes), probiotics and prebiotics (e.g. inulin improving the function of the digestive tract by increasing absorption of nutrients), – vitamin content that regulate metabolism and biochemical changes occurring in bone tissue (e.g. vitamin D3, B6, C and K). This study was based on the results of research experiments from available literature, and studies on growing pigs carried out at the Kielanowski Institute of Animal Physiology and Nutrition, Polish Academy of Sciences. The tests were performed in total on 300 pigs of Duroc, Pietrain, Puławska breeds, line 990 and hybrids (Great White × Duroc, Great White × Landrace), PIC pigs, slaughtered at different body weight during the growth period from 15 to 130 kg. Bones for biomechanical tests were collected after slaughter from each pig. Their length, mass and volume were determined. Based on these measurements, the specific weight (density, g/cm3) was calculated. Then each bone was cut in the middle of the shaft and the outer and inner diameters were measured both horizontally and vertically. Based on these measurements, the following indicators were calculated: • cortical thickness, • cortical surface, • cortical index. Abstract 11 Bone strength was tested by a three-point bending test. The obtained data enabled the determination of: • bending force (the magnitude of the maximum force at which disintegration and disruption of bone structure occurs), • strength (the amount of maximum force needed to break/crack of bone), • stiffness (quotient of the force acting on the bone and the amount of displacement occurring under the influence of this force). Investigation of changes in physical and biomechanical features of bones during growth was performed on pigs of the synthetic 990 line growing from 15 to 130 kg body weight. The animals were slaughtered successively at a body weight of 15, 30, 40, 50, 70, 90, 110 and 130 kg. After slaughter, the following bones were separated from the right half-carcass: humerus, 3rd and 4th metatarsal bone, femur, tibia and fibula as well as 3rd and 4th metatarsal bone. The features of bones were determined using methods described in the methodology. Describing bone growth with the Gompertz equation, it was found that the earliest slowdown of bone growth curve was observed for metacarpal and metatarsal bones. This means that these bones matured the most quickly. The established data also indicate that the rib is the slowest maturing bone. The femur, humerus, tibia and fibula were between the values of these features for the metatarsal, metacarpal and rib bones. The rate of increase in bone mass and length differed significantly between the examined bones, but in all cases it was lower (coefficient b &lt;1) than the growth rate of the whole body of the animal. The fastest growth rate was estimated for the rib mass (coefficient b = 0.93). Among the long bones, the humerus (coefficient b = 0.81) was characterized by the fastest rate of weight gain, however femur the smallest (coefficient b = 0.71). The lowest rate of bone mass increase was observed in the foot bones, with the metacarpal bones having a slightly higher value of coefficient b than the metatarsal bones (0.67 vs 0.62). The third bone had a lower growth rate than the fourth bone, regardless of whether they were metatarsal or metacarpal. The value of the bending force increased as the animals grew. Regardless of the growth point tested, the highest values were observed for the humerus, tibia and femur, smaller for the metatarsal and metacarpal bone, and the lowest for the fibula and rib. The rate of change in the value of this indicator increased at a similar rate as the body weight changes of the animals in the case of the fibula and the fourth metacarpal bone (b value = 0.98), and more slowly in the case of the metatarsal bone, the third metacarpal bone, and the tibia bone (values of the b ratio 0.81–0.85), and the slowest femur, humerus and rib (value of b = 0.60–0.66). Bone stiffness increased as animals grew. Regardless of the growth point tested, the highest values were observed for the humerus, tibia and femur, smaller for the metatarsal and metacarpal bone, and the lowest for the fibula and rib. Abstract 12 The rate of change in the value of this indicator changed at a faster rate than the increase in weight of pigs in the case of metacarpal and metatarsal bones (coefficient b = 1.01–1.22), slightly slower in the case of fibula (coefficient b = 0.92), definitely slower in the case of the tibia (b = 0.73), ribs (b = 0.66), femur (b = 0.59) and humerus (b = 0.50). Bone strength increased as animals grew. Regardless of the growth point tested, bone strength was as follows femur &gt; tibia &gt; humerus &gt; 4 metacarpal&gt; 3 metacarpal&gt; 3 metatarsal &gt; 4 metatarsal &gt; rib&gt; fibula. The rate of increase in strength of all examined bones was greater than the rate of weight gain of pigs (value of the coefficient b = 2.04–3.26). As the animals grew, the bone density increased. However, the growth rate of this indicator for the majority of bones was slower than the rate of weight gain (the value of the coefficient b ranged from 0.37 – humerus to 0.84 – fibula). The exception was the rib, whose density increased at a similar pace increasing the body weight of animals (value of the coefficient b = 0.97). The study on the influence of the breed and the feeding intensity on bone characteristics (physical and biomechanical) was performed on pigs of the breeds Duroc, Pietrain, and synthetic 990 during a growth period of 15 to 70 kg body weight. Animals were fed ad libitum or dosed system. After slaughter at a body weight of 70 kg, three bones were taken from the right half-carcass: femur, three metatarsal, and three metacarpal and subjected to the determinations described in the methodology. The weight of bones of animals fed aa libitum was significantly lower than in pigs fed restrictively All bones of Duroc breed were significantly heavier and longer than Pietrain and 990 pig bones. The average values of bending force for the examined bones took the following order: III metatarsal bone (63.5 kg) &lt;III metacarpal bone (77.9 kg) &lt;femur (271.5 kg). The feeding system and breed of pigs had no significant effect on the value of this indicator. The average values of the bones strength took the following order: III metatarsal bone (92.6 kg) &lt;III metacarpal (107.2 kg) &lt;femur (353.1 kg). Feeding intensity and breed of animals had no significant effect on the value of this feature of the bones tested. The average bone density took the following order: femur (1.23 g/cm3) &lt;III metatarsal bone (1.26 g/cm3) &lt;III metacarpal bone (1.34 g / cm3). The density of bones of animals fed aa libitum was higher (P&lt;0.01) than in animals fed with a dosing system. The density of examined bones within the breeds took the following order: Pietrain race&gt; line 990&gt; Duroc race. The differences between the “extreme” breeds were: 7.2% (III metatarsal bone), 8.3% (III metacarpal bone), 8.4% (femur). Abstract 13 The average bone stiffness took the following order: III metatarsal bone (35.1 kg/mm) &lt;III metacarpus (41.5 kg/mm) &lt;femur (60.5 kg/mm). This indicator did not differ between the groups of pigs fed at different intensity, except for the metacarpal bone, which was more stiffer in pigs fed aa libitum (P&lt;0.05). The femur of animals fed ad libitum showed a tendency (P&lt;0.09) to be more stiffer and a force of 4.5 kg required for its displacement by 1 mm. Breed differences in stiffness were found for the femur (P &lt;0.05) and III metacarpal bone (P &lt;0.05). For femur, the highest value of this indicator was found in Pietrain pigs (64.5 kg/mm), lower in pigs of 990 line (61.6 kg/mm) and the lowest in Duroc pigs (55.3 kg/mm). In turn, the 3rd metacarpal bone of Duroc and Pietrain pigs had similar stiffness (39.0 and 40.0 kg/mm respectively) and was smaller than that of line 990 pigs (45.4 kg/mm). The thickness of the cortical bone layer took the following order: III metatarsal bone (2.25 mm) &lt;III metacarpal bone (2.41 mm) &lt;femur (5.12 mm). The feeding system did not affect this indicator. Breed differences (P &lt;0.05) for this trait were found only for the femur bone: Duroc (5.42 mm)&gt; line 990 (5.13 mm)&gt; Pietrain (4.81 mm). The cross sectional area of the examined bones was arranged in the following order: III metatarsal bone (84 mm2) &lt;III metacarpal bone (90 mm2) &lt;femur (286 mm2). The feeding system had no effect on the value of this bone trait, with the exception of the femur, which in animals fed the dosing system was 4.7% higher (P&lt;0.05) than in pigs fed ad libitum. Breed differences (P&lt;0.01) in the coross sectional area were found only in femur and III metatarsal bone. The value of this indicator was the highest in Duroc pigs, lower in 990 animals and the lowest in Pietrain pigs. The cortical index of individual bones was in the following order: III metatarsal bone (31.86) &lt;III metacarpal bone (33.86) &lt;femur (44.75). However, its value did not significantly depend on the intensity of feeding or the breed of pigs.

AbstractWe investigated the formation of the conductive network of carbon nanotubes (CNTs) in alkali-activated nanocomposites for sulfate-sensing applications. The matrix was a one-part blend of fly ash and ground granulated blast-furnace slag, activated by sodium silicate and water. Sodium dodecylbenzenesulfonate was used as the surfactant for dispersion of the CNTs in the aqueous media. The nanocomposites were investigated by a laboratory-developed setup to study the electrical and sensing properties of the alkali-activated material. The electrical properties (i.e., conductivity) were calculated and assessed to discover the percolation threshold of the nanocomposites. Furthermore, the sensing behavior of nanocomposites was studied upon sulfate ($${\mathrm{SO}}_{4}^{2-}$$ SO 4 2 - ) exposure by introduction of sulfuric acid ($$({\mathrm{H}}_{2}{\mathrm{SO}}_{4})$$ ( H 2 SO 4 ) ) and magnesium sulfate ($${\mathrm{MgSO}}_{4}$$ MgSO 4 ). The sensors were able to preliminarily exhibit a signal difference based on the introduced media ($${\mathrm{H}}_{2}{\mathrm{SO}}_{4} \&amp;\mathrm{ Mg}{\mathrm{SO}}_{4}$$ H 2 SO 4 &amp; Mg SO 4 ), CNT content and $${\mathrm{H}}_{2}{\mathrm{SO}}_{4}$$ H 2 SO 4 volumetric quantity. The results of this research demonstrated a sensing potential of CNT alkali-activated nanocomposites and can be applied in the concrete structural health monitoring.

The chapter presents an analysis of selected magnesium alloys as structural materials to be used in production of parts as well as their technological parameters in some manufacturing processes: metal forming and joining. Taking into account the analysis of microstructure and mechanical properties of conventional and new magnesium alloys and requirements of their possible applications (aviation, automotive, sport, etc.), the study of forming parts/products based on description of plastic formability of magnesium alloys in the processes of bulk metal forming (forging, extrusion, KOBO extrusion, rolling) and joining (friction stir welding) has been presented. Upsetting test, backward extrusion, and KOBO extrusion of complex cross-sectional profiles and forging process were conducted using magnesium alloys such as AZ31, AZ61, AZ80, WE 43, and Mg alloy with Li for the production of thin-walled profiles and forged parts. The range of temperatures and extrusion rate for manufacturing of these profiles were determined. Tests also covered the analysis of microstructure of Mg alloys in the initial state as well as after the extrusion process. The recommendations for realization of metal forming and joining processes of selected magnesium alloys have been presented.

Magnesium alloys are the lightest structural metal. The lightness is the main reason for the interest for Mg in various industrial and clinical applications, in which lightweight structures are in high demand. Recent research and developments on magnesium Mg alloys are reviewed. A particular attention is focused on binary and ternary Mg alloys consisting mainly of Al, Zn, Mn, Ca and rare earth (RE) elements. The effects of different alloying elements on the microstructure, the mechanical and the corrosion properties of Mg alloys are described. Alloying induces modifications of the microstructural characteristics leading to strengthening mechanisms, improving then the ductility and the mechanical properties of pure Mg.

In addition to excellent mechanical, physical and chemical parameters, magnesium oxychloride cement (MOC) composites offer numerous environmental benefits, particularly with regard to the necessary reduction of carbon dioxide emissions associated with the production of Portland cement based building materials. However, the limitation to the wider use of MOC is its low water resistance. Therefore, the possibility of improving the water resistance of magnesium oxychloride cement (MOC) composites by nano-adjustment using fluorographene (FG) was the subject of the research presented. A tannic acid (TA)-based surfactant was used to uniformly disperse the FG particles. The effect of FG added at the dosage of 0.2% and 0.5% by weight of the MOC binder in the MOC mixture was investigated and characterized by the assessment of the mechanical, basic structural and microstructural properties of the hardened composites. Particular attention was paid to the analysis of water resistance, for which the hygric parameters and the softening coefficient were measured after immersing the samples in water for 24 hours. The results obtained showed that FG in the amount of 0.2 wt% of the binder improved the water resistance, while 0.5 wt% of FG in the MOC binder gave results comparable to those of the reference sample. Since FG-doped MOC composites retained the excellent mechanical and structural parameters of MOC, the improvement in water resistance may enable them to more widely exploit their advanced properties and eco-efficiency in construction practice.

Abstract Nonmagnetic drill collars and other structural components are used to provide a region in the bottom hole assembly near the bit in which sensitive magnetic measurements can be made. Beryllium copper, C17200, is paramagnetic with low magnetic permeability which makes it aptly suited for nonmagnetic components. Not only are the magnetic properties of the alloys for these components important, but the integrity of the alloys under dynamic loading in a range of hostile drilling fluids is critical as well. Chlorides in certain drilling muds can cause unpredictable stress corrosion cracking (SCC) of susceptible alloys. In a standard test for chloride SCC, ASTM G 36-73, beryllium copper, C17200, showed no failure after 1000 hr of exposure to boiling 45 weight percent magnesium chloride solution. The applied stresses were 100 percent of the 0.2 percent offset yield strength for the alloy. Failures for austenitic stainless steels generally occurred in less than 200 hr in this environment at applied stresses of 25 percent of the yield strength. Although benefits can be obtained by controlling the environment and introducing residual compressive stresses to austenitic stainless steel components, these remedies cannot permanently eliminate the underlying susceptibility of these alloys to chloride SCC. Beryllium copper is immune to chloride SCC.

Magnesium oxychloride cement (MOC) is commonly known for its eco-friendly properties and versatile applications across various industries. It is often claimed to be inherently fire-resistant, making it a favourable choice for cladding applications, especially in areas prone to wildfires or buildings requiring enhanced fire safety. Moreover, recent development of ductile and water-resistant MOC based composites (MOCC) utilizing supplementary cementitious material, chemical additives and fibres has further opened new avenues for this material in terms of application. Despite this progress, there exists a noticeable lack of research explaining fire resistance of MOC or MOCC, and the mechanisms involved. Additionally, the distinct advantages it offers over alternatives based on ordinary Portland cement (OPC) in terms of spalling resistance remain unclear. Therefore, this study is focused on analysing the fire performance of MOC based composites. 50 mm cubic specimens were tested after subjecting to 200-800°C at a heating rate of 2°C/min and two-hour dwell duration to obtain the residual compressive strength. The results showed a significant decrease in the strength (&gt;95%) of MOCC specimens after exposure to 800°C, highlighting its poor fire performance and raising concerns about its suitability as a structural component. Building upon this finding and seeking to understand the strength loss, differential scanning calorimetry analysis was employed to delve further into the microstructural investigation of MOCC. Furthermore, its spalling resistance was assessed through a novel one-directional spalling test on panels measuring 300mm × 300mm × 20mm based on ISO fire curve. A subsequent comparison was made to an OPC-based cementitious composite with proven high residual performance to showcase distinctions in crack pattern, emphasizing the superior spalling resistance of MOCC and its suitability for non-structural applications.
