Full textAbstract:
Ground and satin stainless steel surfaces are often applied to lend various products a characteristic high-quality appearance. Examples can be found in interior and exterior architecture, passenger elevators, public ticket machines and cover panels of white goods. In everyday use the visual appearance of these products is impaired by soiling. Especially on the surfaces of household appliances fingerprints tend to accumulate. On satin stainless steel parts the cutaneous sebum sticks to the brush marks. Thus extensive cleaning effort is required. Since several years the manufacturers of stainless steel offer satin stainless-steel sheet metal equipped with thin clear coatings for this application. The clear coating fills the brush marks and also causes a better wetting behavior and optimal cleaning properties. In this regard, the term easy-to-clean surface is common.The manufacturers face the challenge of applying a very thin clear coating with an index of refraction adjusted to the satin stainless steel surface and the cutaneous sebum. Thus, ideally the coating should not be distinguishable, concerning haptic and optic properties. The thickness of these coatings amounts to a few micrometers. Therefore, the heat transfer coefficient of the surface only varies minimally and the surface does not feel painted. The advantageous wetting behavior and the slightly differing reflection properties of the clear coating contribute to reducing the adhesion and conspicuousness of fingerprints significantly. Because of these attributes the term anti-fingerprint coatings is used.A further prerequisite for the application of anti-fingerprint coatings in high-quality parts is a good scratch resistance. Therefore, nanoparticle-reinforced coating systems are applied. Typically hard particles like SiO2 or Al2O3 are used. In addition to this, a curing procedure by ultraviolet radiation combined with a suitable solvent-free coating system can be used. This further improves the hardness and scratch resistance of the coating. Due to these requirements the clear coatings are applied in a coil-coating procedure. Consequently, the final painted sheets have to be processed to the respective sheet metal part. Common forming processes for white goods’ panels are bending and crash forming. After forming the final processor does not spend any effort on varnishing or curing on-site which leads to special cost savings in comparison to a piecework coating.The required performance characteristics of the anti-fingerprint coating allow no compromises concerning the coating system with regard to the formability. During forming operations damage is caused to the clear coating in the form of crack formation and delamination. Due to the optical properties of coating systems specifically adjusted to ground stainless steel surfaces, the defects in the clear coating are difficult to identify precisely. However, the properties of the final painted sheet metals’ surface are impaired. This also includes the corrosion resistance which must be taken into account especially for stainless steel applications, e.g. in the kitchen area or in outdoor applications.On the one hand this paper deals with experimental analyses for the identification of the defects caused to an anti-fingerprint clear coating by forming operations. The elaborated procedure is used to identify cracks and delamination due to bending operations. In the experiments mandrel bending specimens of the coated stainless steel sheet metal are formed. Due to different bending radii the intensity of cracks and delamination in the coating varies. But the orientation of the bending edge towards the grinding direction also influences the damage intensity and the damage characteristics. These specimens are also examined in a salt spray test to determine the influence of the different coating damages on the corrosion resistance of the stainless steel substrate. In comparison, the same stainless steel sheet metal material without clear coating is tested simultaneously. The comparison demonstrates the influence of the coating and the deformation-induced damages. On the other hand, to examine the damages as a result of a typical forming process a simplified oven panel is manufactured in a crash forming tool. The front side of the panel remains flat and shows no strains. But along the sharp bending radius, which is typical for the design of high-quality white goods’ applications, cracks in the clear coating can be observed. The experimental results show an influence on the coating damages resulting from the use of a deep draw foil. Furthermore, the forming tool features a heating device and panels are formed at higher temperatures with an effect on the coating damages.

Full textAbstract:
Heavy metals have the potential to interact and induce several stress responses in the plants; thus, effects of heavy metal stress on DNA damages and total antioxidants level inUrtica dioicaleaves and stems were investigated. The samples are sampled from areas with different metal exposition. Metal content was analyzed by Inductively Coupled Plasma-Atomic Emission Spectrometer (ICP-AES), for total antioxidants level assessment the Ferric-Reducing Antioxidant Power (FRAP) assay was used, and genomic DNA isolation from frozen plant samples was performed to obtain DNA fingerprints of investigated plant. It was found that heavy metal contents in stems generally changed synchronously with those in leaves of the plant, and extraneous metals led to imbalance of mineral nutrient elements. DNA damages were investigated by Random Amplified Polymorphic DNA (RAPD) technique, and the results demonstrated that the samples exposed to metals yielded a large number of new fragments (total 12) in comparison with the control sample. This study showed that DNA stability is highly affected by metal pollution which was identified by RAPD markers. Results suggested that heavy metal stress influences antioxidant status and also induces DNA damages inU. dioicawhich may help to understand the mechanisms of metals genotoxicity.

Full textAbstract:
Respiratory diseases often show no apparent symptoms at their early stages and are usually diagnosed when permanent damages have been made to the lungs. A major site of lung pathogenesis is the small airways, which make it highly challenging to detect using current techniques due to the diseases’ location (inaccessibility to biopsy) and size (below normal CT/MRI resolution). In this review, we present a new method for lung disease detection and treatment in small airways based on exhaled aerosols, whose patterns are uniquely related to the health of the lungs. Proof-of-concept studies are first presented in idealized lung geometries. We subsequently describe the recent developments in feature extraction and classification of the exhaled aerosol images to establish the relationship between the images and the underlying airway remodeling. Different feature extraction algorithms (aerosol density, fractal dimension, principal mode analysis, and dynamic mode decomposition) and machine learning approaches (support vector machine, random forest, and convolutional neural network) are elaborated upon. Finally, future studies and frequent questions related to clinical applications of the proposed aerosol breath testing are discussed from the authors’ perspective. The proposed breath testing has clinical advantages over conventional approaches, such as easy-to-perform, non-invasive, providing real-time feedback, and is promising in detecting symptomless lung diseases at early stages.

The purpose of this study was to find out the Fingerprint Function for investigators in disclosing criminal cases of murder and barriers experienced by investigators in conducting evidence with Fingerprint (Dactyloscopy) at the South Sulawesi Regional Police Regional Police Directorate. This study uses a type of qualitative research, by examining and studying a science of fingerprint identification which is used as the basis for conducting problem solving and qualitative analysis. The results of the research are: fingerprint function for investigators in disclosing criminal cases of murder which states that by identifying or observing fingerprints, one can find out one's identity in detail and clearly because as we know in this world no one has a fingerprint. the same so that the fingerprints possessed by humans are not the same and the obstacles of investigators in conducting evidence with the science of fingerprinting, ie the crime scene is no longer in the status quo or the crime scene is damaged so investigators have difficulty identifying fingerprints. This can be seen by the existence of criminal cases of murder in the South Sulawesi Regional Police Headquarters Ditreskrimum

The notary's role is to provide legal protection to the people who use his services. The presence of a Notary is indispensable for the community concerned to hold a legal relationship with other individuals so that the Notary may also be liable. In the provisions of Article 16 paragraph (1) letter c of the Amendment Law, it is stipulated that in carrying out his position, the Notary is required to attach fingerprints on the minutes of the deed, giving rise to various polemics, because the said provisions do not stipulate further if in this case the smoker suffers from finger defects or events that result in damage to fingerprints which makes the investigator unable to put his fingerprint. The purpose of this research is to find out how the efforts that can be done by a notary against those who are unable to put fingerprints and the legal consequences of the absence of fingerprints against the strength of the deed. This research is a type of normative legal research. The results of this study indicate that efforts can be made by a notary if there are those who suffer from finger defects or experience events that cause fingerprint damage so that they cannot attach their fingerprints to the minutes of the deed, the relevant Notary can explain the matter at the end of the deed. he made it because the fingerprints attached to the address are an act that is required to a notary that can lead to administrative sanctions as contained in the Amendment Law. Due to the legal absence of fingerprints attached to the strength of the deed that is the deed made by the relevant Notary Public remains an authentic deed even though the fingerprints of the tappers are not attached based on Article 1869 of the Civil Code and the deed is valid and legally binding as long as the provisions contained in Article 1320 are fulfilled Civil Code.

High technologies at the present stage of development of the world community have penetrated into all spheres of human activity. Considering the issue of digital methods of crime investigation, of course, forensic experts are faced with problems of their effectiveness. Today, most Western countries in the investigation of crimes use fingerprint examination, using technology, thereby reducing the time of investigation, ensuring efficiency. And yet, not all forensic specialists use these techniques when taking fingerprints, relying on the reliability and the usual proven practice of the classical method of fingerprinting. As you know, in the countries of the post-Soviet space, this method was used on the basis of scientific approaches developed by such scientists as E. Henry, A. Bertillon, G. Gross, E. Locard, etc. For example, the work of E. Henry formed the basis for fingerprint registration, since the scientific approach to the biological process of damage and restoration of the epidermis during the investigation of a crime, it is necessary to attach special importance, since papillary lines also have the property of recoverability. If the dermis is damaged, then the pattern is not restored in such an area. But the scars that appear at the same time, the scars themselves become the hallmarks of the pattern. For a century, forensic scientists have studied the sweat marks of handprints for identification, since each fingerprint is different. In this analytical article, the authors made an attempt to conduct an analytical review of the implementation practices of digital fingerprinting in different countries and study the extent to which the effectiveness of its application is possible.

Glutathione (GSH), the protective agent and reducing agent, has been widely used to prepare gold nanoclusters (GSH-Au NCs) with stable fluorescence properties and negative charge of the surface. Meanwhile, polyethyleneimine (PEI) was used as the modification agent to synthesize magnetic ferroferric oxide nanoparticles (Fe3O4) with fantastic dispersibility and positive charge of the surface. Based on the electrostatic adsorption force, magnetic nano-Fe3O4@GSH-Au NCs core–shell microspheres composed of magnetic Fe3O4 nanoparticles modified by PEI as the core and GSH-Au NCs as the shell were assembled. The prepared Fe3O4@GSH-Au NCs microspheres harbored a uniform size (88.6[Formula: see text]nm), high magnetization (29.2[Formula: see text]emu/g) and excellent fluorescence. Due to the coordination bond action between Au atom and sulfhydryl (–SH), amino (–NH2), carboxyl (–COOH) in sweat, Fe3O4@GSH-Au NCs could combine with latent fingerprints. In addition, Fe3O4@GSH-Au NCs with good fluorescence and magnetism could detect fingerprints on various objects. Significantly, the powders were not easy to suspend in the air, which avoided the damage to the health of forensic experts and the fingerprints by only powder contacting. Above all, Fe3O4@GSH-Au NCs was successfully applied to the latent fingerprint visualization, which has great potential in forensic science.

The purpose of this study was to determine the use of fingerprints to support the process of proving evidence in the investigation of criminal cases in the Jambi Regional Police and to determine the effectiveness of fingerprints as supporting evidence in the investigation of criminal cases. The number of criminal cases that occurred in Jambi made the police improve their performance, one of which was in the investigation process by looking for evidence of evidence, one of which was a fingerprint. The results of this study are the use of fingerprints can support the process of proving evidence in the investigation of criminal cases, because the discovery of fingerprints of someone suspected of committing a crime will make it easier for the police to find other evidence, for in Jambi itself the use of fingerprints as preliminary evidence rarely seen from 2016-2019, there were only 5 cases that used fingerprints as an initial guide, because in Jambi itself still had many shortcomings such as at the time of the crime scene many fingerprints were found but many were already damaged, and many criminal acts were indirectly reported, for its own effectiveness the Jambi Regional Police have very complete and sophisticated equipment such as those at the National Police Headquarters and are very effective in terms of cases and tools that all 5 cases that occurred were effective using fingerprints as evidence for initial instructions. Abstrak Tujuan penelitian ini adalah untuk mengetahui penggunaan sidik jari bisa mendukung proses pembuktian alat bukti dalam proses penyidikan perkara pidana di Polda Jambi serta untuk mengetahui efektivitas sidik jari sebagai pendukung alat bukti dalam proses penyidikan perkara pidana. Banyaknya kasus kejahatan yang terjadi di Jambi membuat pihak kepolisian semakin meningkatkan kinerjanya yang salah satunya ialah dalam proses penyidikan dengan mencari bukti petunjuk yang salah satunya sidik jari. Hasil penelitian ini adalah penggunaan sidik jari bisa mendukung proses pembuktian alat bukti dalam proses penyidikan perkara pidana, karena dengan ditemukannya sidik jari seseorang yang diduga melakukan tindak pidana maka akan memudahkan pihak kepolisian dalam mencari bukti lain, untuk di Jambi sendiri penggunaan sidik jari sebagai bukti awal jarang dilakukan terlihat dari tahun 2016-2019 hanya terdapat 5 kasus yang menggunakan sidik jari sebagai petunjuk awal, karena di Jambi sendiri masih memiliki banyak kekurangan seperti pada saat olah TKP banyak ditemukan sidik jari akan tetapi banyak yang sudah rusak, dan banyak kejadian tindak pidana yang tidak langsung dilaporkan, untuk efektivitasnya sendiri Polda Jambi memiliki peralatan yang sangat lengkap dan canggih sudah seperti di Mabes Polri dan sangat efektif dari segi kasus dan alatnya bahwa dari 5 kasus yang terjadi semuanya efektif dengan menggunakan sidik jari sebagai alat bukti petunjuk awal.

Full textAbstract:
The author of the article analyzes existing methods of seizing three-dimensional and latent (two-dimensional) shoeprints, described in the forensic scientific literature, which are used in Ukraine and abroad. Attention is drawn to the fact that methods of seizing traces that have been used for a long time are a subject to minor changes, despite the development of scientific and technological progress. The author names a reason for such a phenomenon: the lack of exchange in experience with countries that use modern tools and techniques for forensic analysis, one of which is a crime scene fingerprint film lift pad. The crime scene fingerprint lift pad is most often used when seizing latent (two-dimensional) shoe prints during inspection of a crime scene. However, attention is drawn to the problem of further suitability of seized traces for carrying out forensic examination as well as to peculiarities of storing seized materials.
According to the author, trace damage is associated with two groups of factors: removal of a trace with violation of a technique and removal of a trace by means of poor-quality material. The author describes several types of crime scene fingerprint lift pad which is used to seize evidence of trace evidence nature.
The author notes that along with the development of technology, trace evidence methods should be advanced as well. There is an urgent need to analyze the market of imported fingerprints, its efficiency, specificity of forensic situations, weather conditions, etc. There is also a need to share experiences in the use of such materials by forensic expert subdivisions. The question as to improving domestic production of fingerprint products, increasing the cost for purchasing high-quality materials also arises. Such an approach will fix the situation with quality of a crime scene processing and collection of evidence which will have a positive impact on detection of crimes and identification of perpetrators. The author emphasizes the relevance of this study and need for new theoretical and practical developments.

The main goal of this thesis was to design and implement a application that would be able to generate fingerprint damage into a synthetic fingerprint. The application can create fingerprint images damaged by pressure, moisture and skin disease dyshidrosis with different intensity of damage. The application also allows annotation of the generated damage and its export. Selected damages were analyzed before the design was created. A database of fingerprints from five users was created to analyze the damage caused by pressure and moisture. The generated images and the achieved results are tested with VeriFinger and FiQiVi. For testing, 19 sets with fingerprints of different intensity and different type of damage were created. Experiments showed that the quality of the fingerprint decreased the most during the generation of moisture with the highest intensity of damage, where the quality decreased by 61.8 %. This thesis can be used for further research in the field of biometric fingerprint processing.

Cílem této práce je návrh a implementace aplikace pro simulaci poškození umělého otisku prstu. Při studiu jsem se soustředil hlavně na projekt SFinGe, který je průkopníkem v této oblasti. Specifikoval jsem přesněji oblast zájmu na optický či kapacitní senzor a poškození otisků prstů v závislosti na tlaku a vlhkosti, poškození a pošpinění senzoru a deformaci pokožky. Navrhl jsem způsob implementace těchto vlivů poškozujících umělý otisk prstu tak, aby se lépe podobal reálným otiskům. Tyto metody využívají morfologické operátory a model plastického zkreslení u otisků prstů. Výsledky nejúspěšnějších metod mají o 62.5% horší skóre v komerčním produktu oproti originálu a o jednu třídu horší hodnocení dle normy pro kvalitu obrazu otisku prstu. Přínosem této práce je tedy poškození umělých otisků tak, že prokazatelně dosahují horších výsledků než originál a návrh aplikace, která umožňuje rozšíření o další metody.

Abstract This research combines analytical and experimental modal analysis techniques to verify the structural integrity or monitor the “health” of a dynamic structure. Central to the procedure is the development of a baseline dynamic fingerprint model of the structure. The dynamic fingerprint is verified with experimental modal analysis and correlation. After the structure is placed into service, damage can be determined by comparing the current dynamic response with the baseline dynamic fingerprint response. The unique aspect of this procedure is that the current dynamic response is enforced on the undamaged baseline dynamic fingerprint model. Should damage exist, the structure is forced to deform in an unnatural manner, and high strain energy results. Significant differences in the normalized modal or operating strain energy density identify structural regions where a loss of stiffness, weakening of the structure, and/or damage has occurred. This identification of a potentially “unhealthy” structural region allows a quick visual inspection of the region or further analytical and/or experimental submodelling of the area to precisely identify the damage. The method is ideally suited to CAE application. The method is demonstrated analytically and experimentally for two structures: an eight-bay cantilevered truss structure and a rectangular plate with various boundary conditions.

Full textAbstract:
Reliability and availability are both critical for competitive operation of high efficiency combined-cycle power plants in the liberalized electricity markets. Monitoring and diagnostic of operational data is successfully used to prevent unexpected plant shut downs and to schedule maintenance activities. A complete set of tools is presented, which is used to monitor combined-cycle power plant operation. The daily incoming data is analyzed with a physics-based performance model, with a neural network-based novelty detection tool and with an experience-based failure detection algorithm, which looks for fingerprints of known and possible component faults. A knowledge management system is used to support the assessment of the findings and the recommended actions are communicated to the power plant operators in the form of early warnings. The application of the different methods in parallel shall ensure that most of the emerging problems are detected before they result in damage that leads to a forced plant shut down. Most of the cases are simple measurement errors, although component deterioration and failures can also be detected. Experience with the ALSTOM early warning system for the GT24/GT26 power plants is shown to demonstrate the successful application of this approach.

Full textAbstract:
Abstract The metallurgical aspects of turbomachinery components, both during manufacture and service intervals, are of particular interest because they dictate performance, degradation, and probability of defect formation. As certaining the microstructural state without destructive cut-ups is difficult. Nondestructive methods such as x-ray diffraction or ultrasonic testing can provide some amount of metallurgical characterization but are limited to surface measurements or point-by-point inspections. Ultrasonic Resonance methods such as Process Compensated Resonance Testing (PCRT) can greatly supplement the inspection and qualification of Industrial Gas Turbine (IGT) blades. The resonance information collected from a component forms a resonance fingerprint, which is dependent on the material, microstructure, geometry, and the presence of defects. PCRT is an established Nondestructive Testing (NDT) method that has seen extensive use in the aerospace industry for both the detection of damage/defects and undesirable microstructural deviations. This experience from aerospace applications can be leveraged for improved metallurgical inspection methodologies in the power generation industry. Here we present and discuss several PCRT case studies from the aerospace industry as well as early PCRT experiences from power generation. Ongoing and upcoming work is also briefly discussed.

Wounds are as unique as a fingerprint. A wound can be a tear, scrape or cut — simply anything that damages the protective layer of skin. Wounds occur anywhere on the body from a small paper cut to a large gash. Because the topology of a wound varies so significantly, current tracing and modeling methods fail to adapt to the changing environment. Similarly, traumatic wounds are a greater challenge to heal without infection due to their nature, size, depth and moisture. Presently, tracing and modeling methods are inaccurate and unreliable for wounds that exceed a certain depth. With any wound, non-invasive, full field methods are necessary to effectively measure and assess the severity of the wound. Due to lack of diagnosis options, wounds are expensive to treat and heal. There are few methodologies that exist to help affect the decision for clinicians regarding wound care, how wounds are evaluated, and how wounds are created. In the U.S., there are an estimated 2.5 million pressure ulcers treated each year in acute care facilities. The epidemiology of pressure wounds result in particular physiological principles that we can use to quantify and determine a baseline wound condition. At the moment, the physician and his experience rather than a standard diagnostic system determines the wound condition. This paper presents methods of quantifying wound progression and their impact thus far on patient care. It also provides open-ended research issues that support the need for a structured, systematic methodology for the modeling and analysis of wound progression. The purpose of this paper is also to disseminate a preliminary epistemology on wound progression and modeling in a quantifiable manner.
