Sähkömagneettisen spektrin, lämpökameratiedustelun ja laser maalinosoituksen tuottama maauhka hälytyspaikka-alueelle

Tämä tutkimus käsittelee sähkömagneettista spektriä ja sen tuottamaa uhkaa lentotukikohdan hälytyspaikka-alue ympäristölle. Sähkömagneettinen spektri on käsitteenä ja uhkan tuottajana laaja käsite, joten tutkimuksessa keskitytään käsittelemään sähkömagneettista spektriä yleisesti uhkan tuottajana, sekä käsitellään sen kahta eri sovellutusta lasermaalinosoitusta ja lämpökameraa uhkan tuottajina tarkemmin. Lähtökohtana työlle on luoda lukijalle kuvasähkömagneettisen spektrin uhkien laajuudesta, tutkimalla itse spektrin ominaisuuksia ja käsittelemällä sen eri sovellutuksia, joihin kuuluu esimerkiksi elektroninen sodankäynti kokonaisuudessaan. Keskeisenä menetelmää tutkimuksessa on laadullinen kirjallisuustutkimus, hyödyntäen kirjallisuuslähteitä sekä sotilas- että siviililähteistä. Lähteet on pyritty valitsemaan siten, että niiden avulla voidaan muodostaa kokonaisvaltainen kuva itse sähkömagneettisesta spektristä, sen ominaisuuksista, laserin muodostamisen periaatteista, lämpökameran toiminnasta ja liittää nämä asiat hälytyspaikka-alueen uhkakuvaan. Yhteenvetona tutkimus on keskittynyt tuloksien valossa luomaan kuvan, kuinka laaja sähkömagneettisen spektrin tuottama uhka on, käsittäen itse spektrin laajuuden ja sovellutusten laajuuden tuottaman uhkakuvan, sekä tarkentaa miten lämpökamera toimii teknisesti tiedustelun välineenä. Lisäksi laser maalinosoitusta käsittelevä osio avaa lukijalle, miten lasersäteen muodostaminen tapahtuu, ja kuinka jopa 4-10km kantamaltaan olevalla lasersäteellä voi valaista maaleja kaukaakin. Johtopäätöksissä summataan yhteen uhkan laajuus, sekä perustellaan miten ja miksi sähkömagneettisen spektrin uhkilta voi suojautua. Spektrin tuottama uhkakuva on sen verran laaja ja kattava, että siltä täysin suojautuminen on mahdotonta, vaan uhkaa on pyrittävä minimoimaan.

The use of confocal laser scanning microscopy to analyze the process of parasitic protozoon-host cell interaction

In this communication we review the results obtained with the confocal laser scanning microscope to characterize the interaction of epimastigote and trypomastigote forms of Trypanosoma cruzi and tachyzoites of Toxoplasma gondii with host cells. Early events of the interaction process were studied by the simultaneous localization of sites of protein phosphorylation, revealed by immunocytochemistry, and sites of actin assembly, revealed by the use of labeled phaloidin. The results obtained show that proteins localized in the interaction sites are phosphorylated. The process of formation of the parasitophorous vacuole was monitored by labeling the host cell surface with fluorescent probes for lipids (PKH26), proteins (DTAF) and sialic acid (FITC-thiosemicarbazide) before interaction with the parasites. Evidence was obtained indicating transfer of components of the host cell surface to the parasite surface in the beginning of the interaction process. We also analyzed the distribution of cytoskeletal structures (microtubules and microfilaments visualized with specific antibodies), mitochondria (visualized with rhodamine 123), the Golgi complex (visualized with C6-NBD-ceramide) and the endoplasmic reticulum (visualized with anti-reticulin antibodies and DIOC6) during the evolution of intracellular parasitism. The results obtained show that some, but not all, structures change their position during evolution of the intracellular parasitism.

Fabrication additive ou Impression 3D. Aperçus sur une variation terminographique

Materiaalia lisäävä valmistus eli 3D-tulostus on valmistusmenetelmä, jossa kappale tehdään 3D-mallin pohjalta materiaalikerroksia lisäämällä, käyttäen useita tekniikoita ja materiaaleja. Menetelmää sovelletaan useilla teollisuuden aloilla. Lisääviä valmistustekniikoita on kehitetty 1990-luvun alkupuolelta lähtien, ja ne monipuolistuvat jatkuvasti. Tässä pro gradu -tutkielmassa tutkitaan sovellusalan terminologian kehitystä vertailevilla menetelmillä ja luodaan kolmikielinen sanasto alan asiantuntijoille, joita edustaa Suomessa FIRPA ry. Sanaston kielet ovat englanti, ranska ja suomi. Terminologian tutkimus on perinteisesti keskittynyt sanastotyöhön ja käsiteanalyysiin, sen sijaan termihistorian tutkimus on ollut vähäisempää. Tässä työssä on tehty vertailevaa termitutkimusta sekä sanastotyön että termihistorian näkökulmista. Vertailutasoja ovat termien merkityksen muuttuminen, vertailu pivot-kielen suhteen ja kielikohtaisten ominaisuuksien tarkastelu termien muotoutumisessa. Tutkittavia asioita ovat sanastokäsitteiden väliset suhteet, synonyymien, varianttien ja uudissanojen moninaisuus, ja termien yleiskielistyminen. Samalla pohditaan muita termien muuttumiseen vaikuttavia syita. Tärkeimpänä lähteenä käytetään Wohlersin vuosiraportteja, jotka kuvaavat kattavasti koko teollisuudenalaa. Koska englannin pivot-vaikutus on voimakasta teknisillä aloilla, omankielisen terminologian kehittyminen vaatii tietoista terminologiatyötä ja aktiivista omankielisten termien käyttöä. Terminologian vakiintumista voidaan arvioida termivarianttien ja uudissanojen määristä, sekä termien yleiskielistymisestä. Terminologia muuttuu jatkuvasti toimialan kehittyessä ja vaatii säännöllistä päivittämistä. Termihistorian tunteminen tukee sanastotyön termivalintoja. Alan asiantuntijat ovat vastuussa omasta terminologiastaan, ja heidän aktiivisuutensa on tärkeää sen kehittämisessä. Toteutettu sanasto on tämän pro gradu -tutkielman liitteenä ja se julkaistaan myös FIRPA ry:n Internet-sivustolla. Suomenkielinen osio sanastosta on ensimmäinen laaja suomeksi julkaistu materiaalia lisäävän valmistuksen sanasto.

Fluvio-morphological processes of meander bends - Combining conventional field measurements, close-range remote sensing and computational modelling

Meandering rivers have been perceived to evolve rather similarly around the world independently of the location or size of the river. Despite the many consistent processes and characteristics they have also been noted to show complex and unique sets of fluviomorphological processes in which local factors play important role. These complex interactions of flow and morphology affect notably the development of the river. Comprehensive and fundamental field, flume and theoretically based studies of fluviomorphological processes in meandering rivers have been carried out especially during the latter part of the 20th century. However, as these studies have been carried out with traditional field measurements techniques their spatial and temporal resolution is not competitive to the level achievable today. The hypothesis of this study is that, by exploiting e increased spatial and temporal resolution of the data, achieved by combining conventional field measurements with a range of modern technologies, will provide new insights to the spatial patterns of the flow-sediment interaction in meandering streams, which have perceived to show notable variation in space and time. This thesis shows how the modern technologies can be combined to derive very high spatial and temporal resolution data on fluvio-morphological processes over meander bends. The flow structure over the bends is recorded in situ using acoustic Doppler current profiler (ADCP) and the spatial and temporal resolution of the flow data is enhanced using 2D and 3D CFD over various meander bends. The CFD are also exploited to simulate sediment transport. Multi-temporal terrestrial laser scanning (TLS), mobile laser scanning (MLS) and echo sounding data are used to measure the flow-based changes and formations over meander bends and to build the computational models. The spatial patterns of erosion and deposition over meander bends are analysed relative to the measured and modelled flow field and sediment transport. The results are compared with the classic theories of the processes in meander bends. Mainly, the results of this study follow well the existing theories and results of previous studies. However, some new insights regarding to the spatial and temporal patterns of the flow-sediment interaction in a natural sand-bed meander bend are provided. The results of this study show the advantages of the rapid and detailed measurements techniques and the achieved spatial and temporal resolution provided by CFD, unachievable with field measurements. The thesis also discusses the limitations which remain in the measurement and modelling methods and in understanding of fluvial geomorphology of meander bends. Further, the hydro- and morphodynamic models’ sensitivity to user-defined parameters is tested, and the modelling results are assessed against detailed field measurement. The study is implemented in the meandering sub-Arctic Pulmanki River in Finland. The river is unregulated and sand-bed and major morphological changes occur annually on the meander point bars, which are inundated only during the snow-melt-induced spring floods. The outcome of this study applies to sandbed meandering rivers in regions where normally one significant flood event occurs annually, such as Arctic areas with snow-melt induced spring floods, and where the point bars of the meander bends are inundated only during the flood events.

3D-tulostustekniikan hyödyntäminen diagnostisten pikatestien tuotekehityksessä

Pikamallinnustekniikat ovat kehittyneet viime vuosina nopeasti. Tämä antaa jo lähes rajat-tomat mahdollisuudet tuottaa 3D-tulostamalla erilaisia tuotteita. 3D-tulostuksen hyödyntä-minen on yleistynyt erityisesti teollisuuden ja teknologian aloilla. Tässä työssä tutkittiin miten 3D-tulostamista voidaan hyödyntää diagnostisten pikatestien tuotekehityksessä. Immunologinen lateral flow-testi on vasta-aineisiin perustuva, nopea ja helppokäyttöinen mittausmenetelmä pienten ainemäärien havaitsemiseen. Tässä työssä kehitettiin lateral flow-testikotelo, jonka suunnitteluun ja rakenteen mallintamiseen käytettiin 3D-tulostustekniikkaa. Testikotelon toimivuus lateral flow- testissä varmistettiin kehittämällä testikoteloon sopiva pikatesti, jonka suorituskykyä analysoitiin sekä visuaalisesti että Actim 1ngeni-lukulaitteella. Työ aloitettiin tutkimalla eri pikavalmistustekniikoita, joista testikotelon tulostamiseen valittiin SLA-tekniikka sen tulostustarkkuuden ja tuotteen pinnan laadun perusteella. Testikotelon suunnittelu aloitettiin määrittämällä millaisia ominaisuuksia testikotelolta haluttiin. Näitä ominaisuuksia olivat lateral flow-testin suojaaminen sekä testissä kulkevan näytteen virtauksen varmistamien. Lateral flow- testin kehityksessä hyödynnettiin osin aiemmin kehitetystä pikatestistä saatuja tietoja. Lateral flow- kasettitestin valmistusprosessi koostui seitsemästä eri prosessivaiheesta jotka olivat: Vasta-aineen/kontrollireagenssin konjugointi, näytetyynyn käsittely, konjugointityynyn käsittely, konjugointityynylle annostelu, membraanille annostelu, tikkujen laminointi ja leikkaus sekä kasettitestin kokoonpano. Kehitetyn lateral flow- kasettitestin toimivuus varmistettiin tutkimalla testin reaktiokinetiikkaa ja analyyttistä herkkyyttä sekä visuaalisesti että lukulaitteen avulla. Tutkimustulosten perusteella 3D-tulostus on erittäin hyödyllinen menetelmä pikatestien tuotekehityksessä suunniteltaessa testikotelorakenteita, näytteen annosteluvälineitä ja näiden yhdistelmiä.

Remote sensing for three-dimensional modelling of hydromorphology

Successful management of rivers requires an understanding of the fluvial processes that govern them. This, in turn cannot be achieved without a means of quantifying their geomorphology and hydrology and the spatio-temporal interactions between them, that is, their hydromorphology. For a long time, it has been laborious and time-consuming to measure river topography, especially in the submerged part of the channel. The measurement of the flow field has been challenging as well, and hence, such measurements have long been sparse in natural environments. Technological advancements in the field of remote sensing in the recent years have opened up new possibilities for capturing synoptic information on river environments. This thesis presents new developments in fluvial remote sensing of both topography and water flow. A set of close-range remote sensing methods is employed to eventually construct a high-resolution unified empirical hydromorphological model, that is, river channel and floodplain topography and three-dimensional areal flow field. Empirical as well as hydraulic theory-based optical remote sensing methods are tested and evaluated using normal colour aerial photographs and sonar calibration and reference measurements on a rocky-bed sub-Arctic river. The empirical optical bathymetry model is developed further by the introduction of a deep-water radiance parameter estimation algorithm that extends the field of application of the model to shallow streams. The effect of this parameter on the model is also assessed in a study of a sandy-bed sub-Arctic river using close-range high-resolution aerial photography, presenting one of the first examples of fluvial bathymetry modelling from unmanned aerial vehicles (UAV). Further close-range remote sensing methods are added to complete the topography integrating the river bed with the floodplain to create a seamless high-resolution topography. Boat- cart- and backpack-based mobile laser scanning (MLS) are used to measure the topography of the dry part of the channel at a high resolution and accuracy. Multitemporal MLS is evaluated along with UAV-based photogrammetry against terrestrial laser scanning reference data and merged with UAV-based bathymetry to create a two-year series of seamless digital terrain models. These allow the evaluation of the methodology for conducting high-resolution change analysis of the entire channel. The remote sensing based model of hydromorphology is completed by a new methodology for mapping the flow field in 3D. An acoustic Doppler current profiler (ADCP) is deployed on a remote-controlled boat with a survey-grade global navigation satellite system (GNSS) receiver, allowing the positioning of the areally sampled 3D flow vectors in 3D space as a point cloud and its interpolation into a 3D matrix allows a quantitative volumetric flow analysis. Multitemporal areal 3D flow field data show the evolution of the flow field during a snow-melt flood event. The combination of the underwater and dry topography with the flow field yields a compete model of river hydromorphology at the reach scale.

Laser scribing of thin-film PV modules

This study is a literature review on laser scribing in monolithically interconnected thin-film PV modules, focusing on efficiency of modules based on absorber materials CIGS, CdTe and a-Si. In thin-film PV module manufacturing scribing is used to interconnect individual cells monolithically by P1, P2 and P3 scribes. Laser scribing has several advantages compared to mechanical scribing for this purpose. However, laser scribing of thin-films can be a challenging process and may induce efficiency reducing defects. Some of these defects can be avoided by improving optimisation or processing methods.

Influence of He-Ne laser therapy on the dynamics of wound healing in mice treated with anti-inflammatory drugs

We determined the effects of helium-neon (He-Ne) laser irradiation on wound healing dynamics in mice treated with steroidal and non-steroidal anti-inflammatory agents. Male albino mice, 28-32 g, were randomized into 6 groups of 6 animals each: control (C), He-Ne laser (L), dexamethasone (D), D + L, celecoxib (X), and X + L. D and X were injected im at doses of 5 and 22 mg/kg, respectively, 24 h before the experiment. A 1-cm long surgical wound was made with a scalpel on the abdomens of the mice. Animals from groups L, D + L and X + L were exposed to 4 J (cm²)-1 day-1 of He-Ne laser for 12 s and were sacrificed on days 1, 2, or 3 after the procedure, when skin samples were taken for histological examination. A significant increase of collagen synthesis was observed in group L compared with C (168 ± 20 vs 63 ± 8 mm²). The basal cellularity values on day 1 were: C = 763 ± 47, L = 1116 ± 85, D = 376 ± 24, D + L = 698 ± 31, X = 453 ± 29, X + L = 639 ± 32 U/mm². These data show that application of L increases while D and X decrease the inflammatory cellularity compared with C. They also show that L restores the diminished cellularity induced by the anti-inflammatory drugs. We suggest that He-Ne laser promotes collagen formation and restores the baseline cellularity after pharmacological inhibition, indicating new perspectives for laser therapy aiming to increase the healing process when anti-inflammatory drugs are used.

The effect of focal point parameters in fiber laser welding of structural steel

In this thesis the effect of focal point parameters in fiber laser welding of structural steel is studied. The goal is to establish relations between laser power, focal point diameter and focal point position with the resulting quality, weld-bead geometry and hardness of the welds. In the laboratory experiments, AB AH36 shipbuilding steel was welded in an I-butt joint configuration using IPG YLS-10000 continuous wave fiber laser. The quality of the welds produced were evaluated based on standard SFS-EN ISO 13919-1. The weld-bead geometry was defined from the weld cross-sections and Vickers hardness test was used to measure hardness's from the middle of the cross-sections. It was shown that all the studied focal point parameters have an effect on the quality, weld-bead geometry and hardness of the welds produced.

Effect of gallium-arsenide laser, gallium-aluminum-arsenide laser and healing ointment on cutaneous wound healing in Wistar rats

This study determined the effects of gallium-aluminum-arsenide laser (GaAlAs), gallium-arsenide laser (GaAs) and Dersani® healing ointment on skin wounds in Wistar rats. The parameters analyzed were: type I and III collagen fiber concentrations as well as the rate of wound closure. Five wounds, 12 mm in diameter, were made on the animals’ backs. The depth of the surgical incision was controlled by removing the epithelial tissue until the dorsal muscular fascia was exposed. The animals were anesthetized with ketamine and xylazine via intraperitoneal injection. The rats were randomly divided into five groups of 6 animals each, according to the treatment received. Group 1 (L4): GaAs laser (4 J/cm²); group 2 (L30): GaAlAs laser (30 J/cm²); group 3 (L60): GaAlAs laser (60 J/cm²); group 4 (D): Dersani® ointment; group 5 (control): 0.9% saline. The applications were made daily over a period of 20 days. Tissue fragments were stained with picrosirius to distinguish type I collagen from type III collagen. The collagen fibers were photo-documented and analyzed using the Quantum software based on the primary color spectrum (red, yellow and blue). Significant results for wound closing rate were obtained for group 1 (L4), 7.37 mm/day. The highest concentration of type III collagen fibers was observed in group 2 (L30; 37.80 ± 7.10%), which differed from control (29.86 ± 5.15%) on the 20th day of treatment. The type I collagen fibers of group 1 (L4; 2.67 ± 2.23%) and group 2 (L30; 2.87 ± 2.40%) differed significantly from control (1.77 ± 2.97%) on the 20th day of the experiment.

Quantitative evaluation of experimental choroidal neovascularization by confocal scanning laser ophthalmoscopy: fluorescein angiogram parallels heparan sulfate proteoglycan expression

The objective of the present study was to develop a quantitative method to evaluate laser-induced choroidal neovascularization (CNV) in a rat model using Heidelberg Retina Angiograph 2 (HRA2) imaging. The expression of two heparan sulfate proteoglycans (HSPG) related to inflammation and angiogenesis was also investigated. CNV lesions were induced with argon laser in 21 heterozygous Zucker rats and after three weeks a fluorescein angiogram and autofluorescence exams were performed using HRA2. The area and greatest linear dimension were measured by two observers not aware of the protocol. Bland-Altman plots showed agreement between the observers, suggesting that the technique was reproducible. After fluorescein angiogram, HSPG (perlecan and syndecan-4) were analyzed by real-time RT-PCR and immunohistochemistry. There was a significant increase in the expression of perlecan and syndecan-4 (P < 0.0001) in retinas bearing CNV lesions compared to control retinas. The expression of these two HSPG increased with increasing CNV area. Immunohistochemistry demonstrated that the rat retina damaged with laser shots presented increased expression of perlecan and syndecan-4. Moreover, we observed that the overexpression occurred in the outer layer of the retina, which is related to choroidal damage. It was possible to develop a standardized quantitative method to evaluate CNV in a rat model using HRA2. In addition, we presented data indicating that the expression of HSPG parallels the area of CNV lesion. The understanding of these events offers opportunities for studies of new therapeutic interventions targeting these HSPG.

Low-level red laser therapy alters effects of ultraviolet C radiation on Escherichia coli cells

Low-level lasers are used at low power densities and doses according to clinical protocols supplied with laser devices or based on professional practice. Although use of these lasers is increasing in many countries, the molecular mechanisms involved in effects of low-level lasers, mainly on DNA, are controversial. In this study, we evaluated the effects of low-level red lasers on survival, filamentation, and morphology of Escherichia colicells that were exposed to ultraviolet C (UVC) radiation. Exponential and stationary wild-type and uvrA-deficientE. coli cells were exposed to a low-level red laser and in sequence to UVC radiation. Bacterial survival was evaluated to determine the laser protection factor (ratio between the number of viable cells after exposure to the red laser and UVC and the number of viable cells after exposure to UVC). Bacterial filaments were counted to obtain the percentage of filamentation. Area-perimeter ratios were calculated for evaluation of cellular morphology. Experiments were carried out in duplicate and the results are reported as the means of three independent assays. Pre-exposure to a red laser protected wild-type and uvrA-deficient E. coli cells against the lethal effect of UVC radiation, and increased the percentage of filamentation and the area-perimeter ratio, depending on UVC fluence and physiological conditions in the cells. Therapeutic, low-level red laser radiation can induce DNA lesions at a sub-lethal level. Consequences to cells and tissues should be considered when clinical protocols based on this laser are carried out.

Low-intensity red and infrared laser effects at high fluences on Escherichia coli cultures

Semiconductor laser devices are readily available and practical radiation sources providing wavelength tenability and high monochromaticity. Low-intensity red and near-infrared lasers are considered safe for use in clinical applications. However, adverse effects can occur via free radical generation, and the biological effects of these lasers from unusually high fluences or high doses have not yet been evaluated. Here, we evaluated the survival, filamentation induction and morphology of Escherichia coli cells deficient in repair of oxidative DNA lesions when exposed to low-intensity red and infrared lasers at unusually high fluences. Cultures of wild-type (AB1157), endonuclease III-deficient (JW1625-1), and endonuclease IV-deficient (JW2146-1) E. coli, in exponential and stationary growth phases, were exposed to red and infrared lasers (0, 250, 500, and 1000 J/cm2) to evaluate their survival rates, filamentation phenotype induction and cell morphologies. The results showed that low-intensity red and infrared lasers at high fluences are lethal, induce a filamentation phenotype, and alter the morphology of the E. coli cells. Low-intensity red and infrared lasers have potential to induce adverse effects on cells, whether used at unusually high fluences, or at high doses. Hence, there is a need to reinforce the importance of accurate dosimetry in therapeutic protocols.

Thick Section Laser Beam Welding of Structural Steels: Methods for Improving Welding Efficiency

Laser beam welding (LBW) is applicable for a wide range of industrial sectors and has a history of fifty years. However, it is considered an unusual method with applications typically limited to welding of thin sheet metal. With a new generation of high power lasers there has been a renewed interest in thick section LBW (also known as keyhole laser welding). There was a growing body of publications during 2001-2011 that indicates an increasing interest in laser welding for many industrial applications, and in last ten years, an increasing number of studies have examined the ways to increase the efficiency of the process. Expanding the thickness range and efficiency of LBW makes the process a possibility for industrial applications dealing with thick metal welding: shipbuilding, offshore structures, pipelines, power plants and other industries. The advantages provided by LBW, such as high process speed, high productivity, and low heat input, may revolutionize these industries and significantly reduce the process costs. The research to date has focused on either increasing the efficiency via optimizing process parameters, or on the process fundamentals, rather than on process and workpiece modifications. The argument of this thesis is that the efficiency of the laser beam process can be increased in a straightforward way in the workshop conditions. Throughout this dissertation, the term “efficiency” is used to refer to welding process efficiency, specifically, an increase in efficiency refers an increase in weld’s penetration depth without increasing laser power level or decreasing welding speed. These methods are: modifications of the workpiece – edge surface roughness and air gap between the joining plates; modification of the ambient conditions – local reduction of the pressure in the welding zone; modification of the welding process – preheating of the welding zone. Approaches to improve the efficiency are analyzed and compared both separately and combined. These experimentally proven methods confirm previous findings and contribute additional evidence which expand the opportunities for laser beam welding applications. The focus of this research was primarily on the effects of edge surface roughness preparation and pre-set air gap between the plates on weld quality and penetration depth. To date, there has been no reliable evidence that such modifications of the workpiece give a positive effect on the welding efficiency. Other methods were tested in combination with the two methods mentioned above. The most promising - combining with reduced pressure method - resulted in at least 100% increase in efficiency. The results of this thesis support the idea that joining those methods in one modified process will provide the modern engineering with a sufficient tool for many novel applications with potential benefits to a range of industries.
