Design and Fatigue Analysis of an LWD Drill Tool
Creators: name: Joshi, Riddhiben Mukesh
Publisher: name: Purdue University Graduate School
Year: 2019
Subjects: Mechanical engineering not elsewhere classified

description: Previous works suggest that 80% to 90% of failures observed in the rotary machines are accounted to fatigue failure. And it is observed that cyclic stresses are more critical than steady stresses when the failure occurred is due to fatigue. One of the most expensive industries involving rotary machines is the Oil and Gas industry. The large drilling tools are used for oil extracts on-shore and off-shore. There are several forces that act on a drilling tool while operating below the earth surface. Those forces are namely pressure, bending moment and torque. The tool is designed from the baseline model of the former tool in Solidworks and Design Molder. Here load acting due to pressure and torque accounts for steady stress i.e., Mean Stress and loading acting due to bending moment account for fluctuating stress i.e., Alternating Stress. The loading and boundary conditions have been adapted from Halliburton’s previous works for LWD drill tool to better estimate the size of the largest possible transducer. The fatigue analysis of static load cases is carried out in Ansys Mechanical Workbench 19.0 using static structural analysis. The simulation is run to obtain results for total deformation, equivalent stress, and user-defined results. The component is designed for infinite life to calculate the endurance limit. Shigley guideline and FKM guideline are compared as a part of a study to select the best possible approach in the current application. The width of the imaging pocket is varied from 1.25 inches to 2.0 inches to accommodate the largest possible transducer with compromising the structural integrity of the tool. The optimum design is chosen based on the stress life theory criteria namely Gerber theory and Goodman Theory.

Il Beowulf nel Novecento: il fumetto e il romanzo
Creators: name: GIUSTI, FRANCESCO

Year: 2006

description: Beowulf, sia come poema sia come personaggio, sta vivendo un periodo di grande fortuna. Due film e un?opera teatrale sono gi� usciti o stanno per uscire tra quest?anno e il prossimo. La ricezione del Beowulf nel XX secolo non � certo ricca come quella, ad esempio, di Ulisse, ma sicuramente ci sono diverse pregevoli opere che riscrivono la storia antico-inglese. Due di queste sono prese in esame in questo articolo: il fumetto italiano Beowulf. Leggenda cristiana dell?antica Danimarca (1940/1941) di Enrico Basari e il romanzo americano Grendel (1971) di John Gardner. Due opere piuttosto differenti: da un lato un graphic novel creato entro una dominante ideologia cattolica durante il Fascismo (e la Seconda guerra mondiale), dall?altro un romanzo ascrivibile alla cosiddetta area Postmoderna che mostra una radicale decostruzione delle ideologie interne e delle narrazioni identitarie. Comunque le due opere si possono accostare in uno sguardo comparatistico, perch� entrambe hanno evidenti legami con i tempi in cui sono state scritte, entrambe sono profondamente radicate nell?ambiente culturale che le ha prodotte. Dallo studio delle riscritture contemporanee � possibile capire se l?antica storia e i suoi personaggi sono ancora vivi e produttivi oggi ed � possibile conoscere qualcosa in pi� del poema medievale.

description: Adenocarcinoma of the pancreas is one of the most aggressive human malignancies. Better models to study tumor behavior in vivo are needed for the development of more effective therapeutics. In the attempt to create clinically relevant models for studying novel treatments directed against pancreatic cancer, we defined a methodology to measure the effect of antineoplastic compounds in established human pancreatic cancer orthotopic xenografts using different luciferized pancreatic cancer cell lines (MiaPaCa-2 and Capan-1) to allow both magnetic resonance and bioluminescence imaging of animals in vivo. Furthermore advanced MRI techniques, such as DWI, were applied to evaluate early response to therapy.

description: The continuous demand for small portable electronics is pushing the semiconductor industry to develop novel lithographic methods to fabricate the elementary structures for microelectronics devices with dimensions reduced size. Self-Assembly of Block copolymers is extremely appealing
due to its excellent compatibility with conventional photolithographic processes, high-resolution patterns and low process costs. This thesis work will focus on the Self-Assembly of cylinderforming Block copolymers as promising next-generation technology for the fabrication of sub-20 nm structures. Two different BCPs were investigated: polystyrene-b- polymethylmethacrylate (PSb-PMMA) and Polystyrene-block- poly(dimethylsiloxane-random-vinylmethylsiloxane) (PS-b-P(DMS-r-VMS)).

description: The use of carbon-ﬁber reinforced composite materials is not novel in the ﬁeld of motorsports industry. Their use in collapsible structures for crashworthiness is however not fully understood and predicted. Due to the complex failure mechanisms occurring within the material, the energy absorbing capacity cannot be easily predicted. The need to understand their contributions in crashworthy structures is thus of great importance. Furthermore, failure of carbon-ﬁber composites is highly dependent on the geometry of structure. Problems arise in both experimental and numerical modelling of these structures. Although many explicit FEA codes exist, they often include experimental parameters that need to be calibrated through either coupon tests or actual crash tests. As composite structures become more commonly used in automotive industry, it is necessary to set some guidelines to successfully model and simulate composite crashworthy structures.
The numerical modelling was done in LS-DYNA Enhanced composite damage MAT54. The material properties were conﬁgured using experimental coupon tests. The tests were conducted on square composite tubes. The Speciﬁc Energy Absorption (SEA) of the tubes were calculated through several coupons. As SEA is a function of geometry, it was necessary to conduct tests with similar geometry as seen in nosecone. MAT54 was chosen to simulate both crush and crash simulations due to its capability to simulate element level crushing. Furthermore, various modiﬁcations within the material model, improve its accuracy to determine composite failure.
The research utilizes the characterization of material inputs in MAT54 by conducting quasi-static compression tests on simpler but similar geometry. By utilizing inputs, a zonal optimization was conducted on the nosecone geometry. The number of layers, layer orientations and ply thicknesses were varied to vary the energy absorbed per zone. The deceleration of the vehicle can thus be controlled, and the weight of the structure could be reduced.

description: Liquid Chromatography tandem Mass Spectrometry (LC-MS) is a powerful tool available to scientists with multidisciplinary applications. In this thesis, LC-MS technique had a key role to perform exciting experiments giving back an outstanding contribute to each project caught up. Different LC-MS instruments were involved. We worked with HPLC and UHPLC systems operating with micro- or nano-flow rates. At the same time, various MS analyzers working in different scan modes (full MS, MS2, MS3, SRM, MRM and DDA) were chosen depending by the expected results. The projects addressed by this thesis were: (1) The identification and characterization of troxerutin degradation products by chemical stability studies. (2) The quantitative evaluation of Adenosine 4'-tetraphosphate (Ap) and Nicotinamide phosphoribosyltransferase (NAMPT) related compounds in B16 cells and in C57BL/6 healthy male mice plasma. (3) The quantitation of serotonin extracellular levels in murine neural progenitor cells. (4) The Identification, quantification and investigation of phosphorylation as post translational modification on NAMPT in B16 cells. For each work, the experimental conditions, the sample handling and preparation, the LC-MS set up and the data analysis were developed and successfully applied.
In conclusion, we demonstrated the versatility, reproducibility and robustness of the LC-MS technique through various chemical and biological applications.

description: The relationship between TMEM132D and depressive symptoms in community populations has not been investigated. Therefore, we explored the association between TMEM132D gene polymorphism and depressive symptoms based on data from a community sample of older adults in Qingdao. A total of 863 older adults were included in this study to examine the relationship between 12 SNPs and depressive symptoms. Depressive symptoms were assessed using the Patient Health Questionnaire-9. Logistic regression analysis was used to analyze the relationship between SNPs and depressive symptoms based on five genetic models. Finally, linkage disequilibrium analysis was performed, and haplotype domains were constructed. We discovered a statistically significant difference between groups with and without depressive symptoms in the genotype and allele frequencies of rs2292723. In addition, multivariate logistic regression showed that rs2292723 and rs2170820 were positively associated with depressive symptoms, and rs61944776 was negatively associated with depressive symptoms. Finally, we found that the haplotype “CTC” of rs2292723, rs492759, and rs61944776 was significantly associated with depressive symptoms by haplotype analysis. Our study suggested that TMEM132D was associated with depressive symptoms, which supplemented the role of the TMEM132D gene in psychiatric disorders.
Examining the Potential Use of Fungi in Forensic Science

Forensic biology

description: Forensic science has gained popularity in the last few decades. Many new techniques are being studied and implemented. It includes a wide range of scientific disciplines, such as entomology, physics and biology. An important improvement to forensic science is the development of different DNA techniques which are implemented during an investigation, making DNA a gold standard for forensics. Most of the time DNA is mentioned it is in terms of human DNA, but there are microscopic organisms with useful DNA. In the last decade, with the development of next-generation sequencing (NGS), studies focusing on bacterial communities have been published, but fungal communities have not been extensively studied. For this project, the potential of fungi in forensic science was investigated through three different studies. Human flora was looked at by NGS from thirty-seven human bodies with differing post-mortem intervals (PMIs). The communities were analyzed statistically and quantitatively, resulting in unique operational taxonomic units (OTUs) and genera which were only present in certain PMIs, and in some which were present through the entire PMI time scale. These attributes can help, not only to give a better view on human mycoflora during decomposition, but they can also help in determining fungal signatures during decomposition. These signatures can help in a PMI determination. Moreover, swine carcasses – the model animals for human forensic studies – were investigated as well to create a checklist of fungal flora after five months of winter decomposition in the West Lafayette, Indiana area. Furthermore, due to the increased importance of wildlife forensics, a wildlife study was also conducted using four wildlife species (mute swan, red tailed hawk, river otter, bobcat). The fungal flora from these species were compared within species at the beginning of the study and at skeletonization stage to look at any indicator fungal species and to create a general checklist for wildlife studies in the West Lafayette, Indiana area for future studies. Additionally, the fungal communities were compared across species as well.
MODULAZIONE DEL CFTR DA PARTE DELLA VARIANTE IPERTENSIVA DELLA PROTEINA CITOSCHELETRICA ADDUCINA
Creators: name: SASSONE, FRANCESCA
Publisher: name: Universit� degli Studi di Milano
Year: 2013

description: CFTR (Cystic Fibrosis Transmembrane Conductance Regulator) is a chloride channel, expressed in the kidney, whose activity and localization are influenced by the cytoskeleton, in particular by actin and its polymerization state. In this study, a possible functional modification of CFTR activity and expression, led by the expression of the hypertensive mutations of adducin (G460W-S586C in humans), an actin capping protein, has been investigated.
The experiments were performed on HEK293 T cells cotransfected with CFTR and the human wild-type or mutated adducin. In whole-cell patch-clamp experiments, both the CFTR chloride current and the slope of current activation after forskolin addition were significantly higher in HEK cells overexpressing mutated adducin. A higher plasma membrane density of active CFTR channels in the presence of mutated adducin, was confirmed by cell-attached patch-clamp experiments. Western blot and biotinylation experiments demonstrated an increased CFTR expression in the plasma membrane, in the presence of the mutated adducin. FRET (Fluorescence Resonance Energy Transfer) experiments showed a significant but weak interaction between CFTR and adducin, while coimmunoprecipitation experiments failed to reveal a clear interaction between the two proteins. A higher retention of CFTR in the plasma membrane was demonstrated both by FRAP (Fluorescence Recovery After Photobleaching) and photoactivation experiments.
The present data indicate that, in HEK cells, the presence of the G460W-S586C hypertensive variant of adducin increases CFTR channel activity, possibly by altering its membrane turnover and inducing a retention of the channel in the plasma membrane. Since CFTR is known to modulate the activity of many others transport systems, the increased surface expression of the channel could have consequences on the whole network of transport in kidney cells.

description: Monitoring wildlife infectious agents requires acquiring samples suitable for analyses, which is often logistically demanding. A possible alternative to invasive or non-invasive sampling of wild-living vertebrates is the use of vertebrate material contained in invertebrates feeding on them, their feces, or their remains. Carrion flies have been shown to contain vertebrate DNA; here we investigate whether they might also be suitable for wildlife pathogen detection. We collected 498 flies in Taï National Park, Côte d’Ivoire, a tropical rainforest and examined them for adenoviruses (family Adenoviridae), whose DNA is frequently shed in feces of local mammals. Adenoviral DNA was detected in 6/142 mammal-positive flies. Phylogenetic analyses revealed that five of these sequences were closely related to sequences obtained from local non-human primates, while the sixth sequence was closely related to a murine adenovirus. Next-generation sequencing-based DNA-profiling of the meals of the respective flies identified putative hosts that were a good fit to those suggested by adenoviral sequence affinities. We conclude that, while characterizing the genetic diversity of wildlife infectious agents through fly-based monitoring may not be cost-efficient, this method could probably be used to detect the genetic material of wildlife infectious agents causing wildlife mass mortality in pristine areas.

description: Shortage of human organs forced the development of xenotransplantation using cells, tissues, and organs from pigs. Xenotransplantation may be associated with the transmission of porcine zoonotic microorganisms, among them the porcine cytomegalovirus (PCMV). To prevent virus transmission, pigs have to be screened using sensitive methods. In order to perform regular follow-ups and further breeding of the animals, samples for testing should be collected by low-invasive or non-invasive methods. Sera, ear biopsies, as well as oral and anal swabs were collected from ten 10-day-old Aachen minipigs (AaMP) and tested for PCMV using sensitive nested polymerase chain reaction (PCR) as well as uniplex and duplex real-time PCR. Porcine cytomegalovirus DNA was detected most frequently in oral and anal swabs. Comparison of duplex and uniplex real-time PCR systems for PCMV detection demonstrated a lower sensitivity of duplex real-time PCR when the copy numbers of the target genes were low (less 200). Therefore, to increase the efficacy of PCMV detection in piglets, early testing of oral and anal swabs by uniplex real-time PCR is recommended.
FAILURES IN SPACECRAFT SYSTEMS: AN ANALYSIS FROM THE PERSPECTIVE OF DECISION MAKING

Subjects: Mechanical engineering not elsewhere classified

description: Space mission-related projects are demanding and risky undertakings because of their complexity and cost. Many missions have failed over the years due to anomalies in either the launch vehicle or the spacecraft. Projects of such magnitude with undetected flaws due to ineffective process controls run into unwarranted cost, schedule overruns and account for huge losses. Such failures continue to occur despite the studies on systems engineering process deficiencies and the best systems engineering practices in place. To understand the reasons behind such failures, this work analyses some of the major contributing factors behind majority of space mission technical failures. To achieve this objective, we analyzed the failure data of space missions that happened over the last decade. Based on that information, we analyzed the launch-related failure events from a design decision-making perspective by employing failure event chain-based framework. By analyzing the failure events with this framework, we identify some dominant cognitive biases that might have impacted the overall system performance leading to unintended catastrophes.
The ability of any design team to achieve optimal performance is limited by communication and knowledge deficiencies between highly dissimilar subsystems. These inefficiencies work to bias each subsystem engineer to prioritize the utility provided by the subsystem they are responsible for. In order to understand how engineering design decisions are influenced by the presence of cognitive biases, the second part of this study establishes a mathematical framework for utility-based selection based on Cumulative Prospect Theory. This framework captures the effect of cognitive biases on selection of alternatives by a rational decision-maker.
From the first study, overconfidence and anchoring biases are identified as the two dominant contributing factors that influenced the decisions behind majority of the failures. The theoretical models developed in the second study are employed to depict the influence of biased decision-making on utility-based selection of alternatives for an earth-orbiting satellite's power subsystem. Predictions from these models show a direct correlation between the decision-maker's biased preference structure and local change in utility curve depicting the (negative) influence of cognitive biases on decision-maker's choice(s).

description: In Deutschland ist die Impfung gegen saisonale Influenza bei Schwangeren seit 2010 und die gegen humane Papillomaviren (HPV) bei Mädchen seit 2007 empfohlen. Niedergelassene Gynäkologinnen und Gynäkologen nehmen bei der Kommunikation und Impfung der beiden Zielgruppen eine wichtige Rolle ein. Darüber hinaus sollten auch medizinisches Personal sowie Menschen ab 60 Jahren und Personen mit chronischer Grunderkrankung die Impfung gegen saisonale Influenza erhalten. Ziel der vorliegenden Erhebung war es, einen ersten Einblick zu gewinnen, inwiefern die Influenza- und HPV-Impfempfehlungen in gynäkologischen Praxen umgesetzt werden. Im Rahmen der vom Robert Koch-Institut (RKI) und der Bundeszentrale für gesundheitliche Aufklärung (BZgA) gemeinsam durchgeführten Kampagne „Wir kommen der Grippe zuvor“ wurde im September 2014 ein Fragebogen zusätzlich zu den Medienpaketen zur Influenzaimpfaufklärung bundesweit an 7477 niedergelassene Gynäkologinnen und Gynäkologen verschickt. Es wurden Daten aus 1469 (20 %) Praxen in die Analysen einbezogen. 72 % der befragten Ärztinnen und Ärzte lassen sich jährlich gegen Influenza impfen. Die Mehrheit der Niedergelassenen empfahl Schwangeren die Impfung gegen saisonale Influenza (93 %) sowie Mädchen und jungen Frauen die HPV-Impfung (97 %). Von denjenigen, die keine Empfehlung aussprachen, wurden als Hauptgründe gegen die Influenzaimpfung Sicherheits- und gegen die HPV-Impfung Wirksamkeitsbedenken angegeben. Gegen beide Impfungen wurde zusätzlich aufgeführt, dass ein Aufklärungsgespräch zu aufwendig sei. Die in unserer Studienpopulation hohe Akzeptanz der beiden Impfungen spiegelt sich nicht in den für Deutschland verfügbaren Impfquoten wider. Gynäkologinnen und Gynäkologen müssen verstärkt auf ihre wichtige Rolle in der Impfprävention hingewiesen werden. Sowohl während der medizinischen Ausbildung als auch in weiterführenden gynäkologischen Fort- und Weiterbildungen sollte das Thema Impfen und die Kommunikation hierzu vermehrt berücksichtigt werden.

NITROGEN DOPED CARBON CATALYSTS FOR ELECTROCHEMICAL OXYGEN REDUCTION REACTION

description: Energy issues have a prominent position in the economy and development at a world level. The automotive sector is at present based almost entirely upon the internal combustion engine and, therefore, is highly dependent on petroleum derived fuels.
Polymer electrolyte membrane (PEM) fuel cells are clean and attractive power generators for transportation and mobile applications due to their high energy conversion efficiency, low operating temperature and low environmental impact. However their practical use continues to be hindered by the high cost of the platinum based catalysts that are needed to improve the slow kinetics of the electrochemical oxygen reduction reaction (ORR) at as low operating temperatures as T ~ 80-120 �C.
To reduce catalysts cost two different approaches are used, the first one being to reduce platinum loading using highly dispersed metal particles (nanoparticles, films) and platinum alloys; the other one consisting of using metal-free or non-precious metal loaded (Fe, Co) nitrogen doped carbons.
Along this line Co/N/C and Fe/N/C catalysts were synthesized and their activity for ORR was investigated manly with electrochemical methods (Thin Film Rotating Disk Electrode, TFRDE, technique and Membrane Electrolyte Assembly, MEA). Others methods like potentiometric titrations, SEM-EDX analysis and thermal analysis were used to characterized carbon support and catalysts.
The investigation of commercial Pt/C catalyst was performed with the RDE, varying the electrode structure and component concentrations, catalyst layer thickness, overlayer Nafion film thickness and Nafion concentration inside the catalyst layer. This latter parameter was found to affect the reagents diffusion (O2, H+) inside the catalyst layer.
 Results were used to outline some criteria that have to be obeyed to obtain reliable RDE data on supported catalysts.
Nitrogen doped carbons were synthesized by amine introduction onto high surface area commercial carbons. A synthesis based on stoichiometric amination of acid oxygen carbon groups, produced un-effective catalyst for ORR, also using different amine compounds, metal ions and carbon support. An effective carbon modification was obtained by pyrolysis of a completely flooded carbon precursor with a liquid amino compound in which metal ions are dissolved.
The effect of Nafion on the diffusion current inside the catalyst layer is stronger in Pt-free than Pt/C catalyst, with different trends of dependence of the Nafion/catalyst ratio.
Effective catalyst were also obtained by carbonization of a hard templated glucose/histidine precursor with different Fe/Cu ratio. Metal loading and reagent molar ratio effects were investigated by BET, XPS and electrochemical methods.

description: Additive manufacturing (AM) or 3D printing has gained significant advancement in recent years. However the potential of 3D printed metals still has not been fully explored. A main reason is the lack of accurate knowledge of the load capacity of 3D printed metals, such as fatigue behavior under cyclic load conditions, which is still poorly understood as compared with the conventional wrought counterpart.
The goal of the thesis is to advance the knowledge of fatigue behavior of 15-5 PH stainless steel manufactured through laser powder bed fusion process. To achieve the goal, a combined numerical and experimental study is carried out. First, using a rotary fatigue testing experiment, the fatigue life of the 15-5 PH stainless steel is measured. The strain life curve shows that the numbers of the reversals to failure increase from 13,403 to 46,760 as the applied strain magnitudes decrease from 0.214\% from 0.132\%, respectively. The micro-structure analysis shows that predominantly brittle fracture is presented on the fractured surface. Second, a finite element model based on cyclic plasticity including the damage model is developed to predict the fatigue life. The model is calibrated with two cases: one is the fatigue life of 3D printed 17-4 stainless steel under constant amplitude strain load using the direct cyclic method, and the other one is the cyclic behavior of Alloy 617 under multi-amplitude strain loads using the static analysis method. Both validation models show a good correlation with the literature experimental data. Finally, after the validation, the finite element model is applied to the 15-5 PH stainless steel. Using the direct cyclic method, the model predicts the fatigue life of 15-5 PH stainless steel under constant amplitude strain. The extension of the prediction curve matches well with the previously measured experimental results, following the combined Coffin-Manson Basquin Law. Under multi-amplitude strain, the kinematic hardening evolution parameter is incorporated into the model. The model is capable to capture the stresses at varied strain amplitudes. Higher stresses are predicted when strain amplitudes are increased. The model presented in the work can be used to design reliable 3D printed metals under cyclic loading conditions.

description: Con la expulsi�n de los moriscos de 1609-1613 termina un
largo cap�tulo de la historia espa�ola. La mayor�a de los historiadores
insiste en que la medida tuvo un complejo origen, pol�tico
y cultural am�n de religioso.1
La decisi�n se justifica en las obras de numerosos apologistas,
como Dami�n Fonseca, cuyo Del giusto scacciamento de
moreschi da Spagna se publica por primera vez traducido al italiano,
en Roma, en 1611, y solo el a�o siguiente en espa�ol.
Las relaciones de sucesos participan en la propaganda favorable a la expulsi�n difundiendo en estos
mismos a�os una imagen negativa de los moriscos. El prop�sito de este trabajo es ver la dial�ctica entre casos y
estereotipos en textos en italiano de diferentes g�neros, entre
ellos relaciones de sucesos, panfletos, poemas sat�ricos que tratan
el tema de la expulsi�n.

description: Freeze-thawing kidneys prior to homogenization is widely accepted in renal research. This study demonstrates that if kidneys are freeze-thawed just once prior to homogenization, immunoblot signals are reduced in a transporter specific manner in rats and mice dependent on sex, and that immunoblot signals can be partially recovered by adding additional protease inhibitors. These findings underscore the critical importance of assessing the impact of sample preparation, including freeze-thaw vs. fresh, to ensure robust rigor and reproducibility.

description: High-performance fibers used for ballistic protection are characterized by having outstanding mechanical properties such high modulus and strength. These mechanical properties are granted by the fiber’s chemical and physical structure as well as their high degree of orientation. Twaron fibers are one of the most commonly used fibers on soft body armors such as bulletproof vests. They are made from poly (p-phenylene terephthalamide) (PPTA), a rigid-rod and highly crystalline polymer. Although these fibers are crystalline and have great mechanical properties, their performance can decrease when they are exposed to different degradation factors. Free volume is the unoccupied space between the polymer molecules. It is responsible for characteristics such as diffusion and viscosity. Hence, the free volume changes as the polymer degrades. This thesis focuses on the effects of sonication, pH changes, and sweat on the free volume of PPTA fibers.
 A non-destructive technique known as positron annihilation lifetime spectroscopy (PALS) was used to measure the free volume in PPTA. Changes in the free volume of fibers degraded under different conditions were compared to their mechanical performance. Degradation in DI water, pH 4 and pH 10 aqueous solutions was conducted for 10 weeks at 80oC. Sweat degradation of PPTA fibers was also conducted for 10 weeks at 25oC, 50oC, and 100oC. Fibers degraded in pH4 and sweat solutions had greater loss of mechanical performance and changes in the free volume. PALS was able to detect changes in the nanostructure of PPTA fibers at early stages of degradation. This data was supported by mechanical tests and is complementary to other characterization techniques such as small angle X-ray scattering (SAXS). Results of this research are a steppingstone for future studies on lifetime predictions of bulletproof vests and the development of the next generation of soft body armors.

description: Resumen

Basado en la patente: soluciones y composiciones de agua biomimética, su uso como y en productos para el cuidado de la salud y la belleza y los métodos para prepararlos. Autor: Cólico Miroslav. 

Desde hace miles de años, se han utilizado diferentes tipos de productos de belleza en diferentes civilizaciones como el antiguo Egipto, el imperio romano, la nobleza inglesa, entre otros, donde claramente dichos productos contenían ingredientes tóxicos que perjudicaban a la salud. El objetivo principal de la ponencia de agua biomimética es dar conciencia a la comunidad científica, y al público en general la importancia de utilizarla en los productos de higiene y belleza del mercado, ya que como es bien sabido, muchos de los componentes microbicidas de los productos comerciales como alcoholes en el maquillaje suelen causar irritabilidad, ardor, resequedad, etc. Hay agentes microbicidas inorgánicos que también se han descrito y utilizado en productos para el cuidado de la belleza, el peróxido de hidrógeno ha sido el más popular, por demás, se han descrito otros agentes que liberan lentamente oxígeno naciente. 

El agua biomimética se utiliza de forma microbicida con numerosos oxidantes diferentes a base de cloro, al pH deseado en los productos de salud y belleza, con el fin de reducir o anular el uso de alcoholes, aceite y surfactante. 

El procedimiento que se utiliza para lograr este propósito es preparar mezclas de agua a base de agua de oxidantes e hipoclorito puro. El método utiliza electroquímica para producir agua activada con numerosos oxidantes a base de cloro, luego se le agrega peróxido de hidrógeno a esa solución y el pH se ajusta en 6, se puede usar filtros catalíticos de cloro o dispositivos de rociado de aire para eliminar el exceso de cloro libre. 

El potencial redox de dicha agua puede variar entre 1300 mV y 650 mV. Si se necesita estabilidad a largo plazo, los mejores resultados se logran con el agua con pH alrededor de 5.5 y potencial redox alrededor de 750 mV. Esta agua es estable durante más de un año. Esta agua es la que se utiliza como sustituto en los artículos de belleza.
