BackgroundIncreasing evidence has elucidated the clinical significance of tumor infiltrating immune cells in predicting outcomes and therapeutic efficacy. In this study, we comprehensively analyze the tumor microenvironment (TME) immune cell infiltrations in clear cell renal cell carcinoma (ccRCC) and correlated the infiltration patterns with anti-tumor immunity and clinical outcomes.MethodsWe analyzed immune cell infiltrations in four independent cohorts, including the KIRC cohort of 533 patients, the Zhongshan ccRCC cohorts of 259 patients, the Zhongshan fresh tumor sample cohorts of 20 patients and the Zhongshan metastatic ccRCC cohorts of 87 patients. Intrinsic patterns of immune cell infiltrations were evaluated for associations with clinicopathological characteristics, underlying biological pathways, genetic changes, oncological outcomes and treatment responses.ResultsUnsupervised clustering of tumor infiltrating immune cells identified two microenvironment subtypes, TMEcluster-A and TMEcluster-B. Gene markers and biological pathways referring to immune evasion were upregulated in TMEcluster-B. TMEcluster-B associated with poor overall survival (p<0.001; HR 2.629) and recurrence free survival (p=0.012; HR 1.870) in ccRCC validation cohort. TMEcluster-B cases had worse treatment response (p=0.009), overall survival (p<0.001; HR 2.223) and progression free survival (p=0.015; HR 2.7762) in metastatic ccRCC cohort. The predictive accuracy of International Metastatic Database Consortium risk score was improved after incorporation of TME clusters.ConclusionsTMEcluster-A featured increased mast cells infiltration, prolonged survival and better treatment response. TMEcluster-B was a heavily infiltrated but immunosuppressed phenotype enriched for macrophages, CD4+T cells, Tregs, CD8+T cells and B cells. TMEcluster-B predicted dismal survival and worse treatment response in clear cell renal cell carcinoma patients.

For a world that is constantly trying to speed up every procedure while obtaining the maximum result, traditional orthodontics have the biological limitation of using light and constant forces that allow tooth movement in a time frame that is only sometimes short. The treatment time could be lengthened if surgical procedures are programmed in the plan. Methods to accelerate tooth movement and reduce the duration of treatment while minimising complications are investigated and reported in the dental literature (e.g., low-level laser therapy, corticotomy, and micro-osteoperforations). This systematic review aims to analyse and summarise the strategies for quickening orthodontic movement during extraction orthodontic treatment, including any potential drawbacks or adverse consequences. The review will evaluate each approach’s effectiveness, safety, and evidence quality, compare their benefits and disadvantages, and analyse the implications for clinical practice and future research. Pubmed, Science Direct, Scopus, and Web of Science were searched using the keywords “acceleration” AND “dental movement” AND “orthodontic” between 1 April 2003 and 1 April 2023. After carefully scanning the study findings, forty-four publications were chosen for the systematic review. Most therapies discussed and provided in the literature seem promising and successful in enhancing orthodontic treatments. The success of operations like corticotomies, piezo-incisions, micro-osteoperforations, osteogenic distraction, low-level laser therapy, the administration of pharmacological treatments, and infiltrations with PRF and PRP were statistically significant and appear to be promising and effective in optimising orthodontic treatments. These strategies expedite treatment and enhance the patient experience, potentially broadening orthodontic appeal and minimising issues like cavities and enamel demineralisation. Further studies, with larger samples and standardised treatment protocols, are needed to investigate the efficacy of these tooth movement acceleration modalities.

Abstract Colorectal cancer (CRC) is one of the most common malignancies and causes of cancer deaths in Finland. Increased number of tumor-infiltrating immune cells has been associated with improved survival in CRC. However, accurate, reproducible analysis methods, as well as better understanding of the interrelationships between different inflammatory markers would be important in order to establish a valuable prognostic and potentially predictive tool. In these studies, a computer-assisted method for the analysis of the densities of tumor-infiltrating immune cells and a quantitative method for the evaluation of CRC-associated lymphoid reaction (CLR) were adopted and validated. Utilizing the new methods, the inflammatory cell infiltration was characterized in independent groups of 418 (Cohort 1) and 149 (Cohort 2) CRC patients. Serum matrix metalloproteinase-8 (MMP-8) levels were measured in Cohort 2 and in a control group of 83 healthy age- and gender-matched controls. The automated cell counting method was found accurate and reproducible. In the tumor samples, there were high positive correlations between different types of immune cells, with the exception of mast cells and CD1a+ immature dendritic cells. High numbers of T cells predicted improved disease-free survival. High CLR density correlated with low tumor stage, but also with better survival regardless of stage. The median serum MMP-8 level of the patients was more than three times higher than that of the healthy controls. In conclusion, the present studies provide insight into the significance of various immune cell types and inflammatory markers in CRC and validate new methods for the analysis of immune cell infiltration in CRC. The results suggest that, especially, the densities of tumor-infiltrating T cells and CLR represent relevant prognostic indicators in CRC. Further studies are needed to evaluate the potential value of serum MMP-8 as an aid for CRC diagnostics, surveillance, or prognostication
Tiivistelmä Kolorektaalisyöpä on yksi yleisimmistä pahanlaatuisista kasvaintaudeista ja syöpäkuolemien aiheuttajista Suomessa. Tulehdussolujen korkean määrän kasvainnäytteissä on havaittu olevan yhteydessä potilaiden parempaan ennusteeseen. Tarkat ja luotettavat analyysimenetelmät sekä tieto eri tulehdusmerkkiaineiden keskinäisistä yhteyksistä olisivat tärkeitä, jotta tulehdussolukon määritystä voitaisiin luotettavasti käyttää potilaiden ennusteen arviointiin. Tutkimuksessa otettiin käyttöön ja validoitiin uusi tietokonepohjainen menetelmä kasvaimen tulehdussolukon arviointiin sekä uusi menetelmä kolorektaalisyövän imukeräsreaktion arviointiin. Kasvainnäytteiden tulehdussolukon määrää ja laatua analysoitiin itsenäisissä 418 (Kohortti 1) ja 149 (Kohortti 2) kolorektaalisyöpäpotilaan aineistoissa uusia menetelmiä hyödyntäen. Lisäksi kohortilta 2 sekä 83 terveeltä ikä- ja sukupuolivalikoidulta verrokilta määritettiin seerumin matriksin metalloproteinaasi-8 (MMP-8) -taso. Tietokonepohjaisen kuva-analyysin tarkkuus ja toistettavuus todettiin erinomaiseksi. Kasvainnäytteistä analysoitujen tulehdussolutyyppien määrät olivat riippuvaisia toisistaan mast-soluja ja CD1a+ epäkypsiä dendriittisoluja lukuun ottamatta. T-solujen runsas määrä oli yhteydessä taudin vähäisempään uusiutumisriskiin. Korkea imukerästiheys kasvainnäytteissä oli yhteydessä matalaan levinneisyysasteeseen sekä potilaiden parempaan ennusteeseen levinneisyysasteesta riippumatta. Seerumin MMP-8-tason mediaani oli potilailla yli kolme kertaa korkeampi kuin terveillä verrokeilla. Tutkimus tuo lisätietoa eri tulehdussolutyyppien ja tulehdusmerkkiaineiden merkityksestä kolorektaalisyövässä, ja sen tuloksena validoitiin uusia tulehdussolukon analysointimenetelmiä. Tulosten perusteella erityisesti kasvaimen alueen T-solujen ja imukerästen tiheys tuovat hyödyllistä tietoa potilaiden ennusteesta. Lisätutkimuksia tarvitaan seerumin MMP-8:n mahdollisesta soveltuvuudesta kolorektaalisyövän diagnostiikan, seurannan tai ennusteen määrittämisen apuvälineeksi

Les propriétés hydrodynamiques du sol jouent un rôle essentiel dans le transfert d’eau en micro-irrigation. Les objectifs de cette thèse sont d’évaluer l’évolution spatio-temporelle des paramètres hydrodynamiques de parcelles irriguées en goutte à goutte, GàG, et d’analyser leurs impacts sur le transfert d’eau au moyen de la modélisation. Les paramètres hydrodynamiques, déterminés à l’aide de la méthode Beerkan, évoluent tout au long du cycle cultural sous l’effet de l’irrigation et de la croissance racinaire. L’analyse géostatistique a permis de vérifier la stabilité de la structure spatiale de ces paramètres, indépendante de la méthode d’infiltration et dépendante de la méthode de calcul. La modélisation analytique et numérique ont indiqué que l’impact de ces deux variabilités sur l’évolution des profils d’humidité, est négligeable dans notre contexte agro-pédoclimatique. Le rôle hydrodynamique du sol semble ainsi limité à un simple facteur d’échange entre le goutteur et les racines
Soil water flows under drip irrigation are heavily reliant on soil hydraulic properties. The main objectives of this thesis are to assess the spatio-temporal change in soil hydraulic properties on drip-irrigated fields, and to analyze their impacts on the water flow through modelling. Soil hydraulic properties, determined by the Beerkan method, underwent changes during the drip-irrigated cropping cycle. These changes were defined as irrigation effects and root growth. A geostatistical analysis was used to examine the stability of the spatial structure of soil hydraulic properties, independent of the infiltration method but dependent on the method of soil hydraulic parameterization. The analytical and numerical simulations show that spatio-temporal changes in topsoil hydraulic properties has no significant effect on soil moisture distribution under our agro-pedo-climatic conditions. The role of soil seems limited to that of a simple exchange factor between the emitters and the roots

Nous étudions la propagation et la quantification d'incertitudes paramétriques au travers de modèles hydrologiques pour la simulation des processus d'infiltration et d'érosion en présence de pluie et/ou de ruissellement. Les paramètres incertains sont décrits dans un cadre probabiliste comme des variables aléatoires indépendantes dont la fonction de densité de probabilité est connue. Cette modélisation probabiliste s'appuie sur une revue bibliographique permettant de cerner les plages de variations des paramètres. L'analyse statistique se fait par échantillonage Monte Carlo et par développements en polynômes de chaos. Nos travaux ont pour but de quantifier les incertitudes sur les principales sorties du modèle et de hiérarchiser l'influence des paramètres d'entrée sur la variabilité de ces sorties par une analyse de sensibilité globale. La première application concerne les effets de la variabilité et de la spatialisation de la conductivité hydraulique à saturation du sol dans le modèle d'infiltration de Green--Ampt pour diverses échelles spatiales et temporelles. Notre principale conclusion concerne l'importance de l'état de saturation du sol. La deuxième application porte sur le modèle d'érosion de Hairsine--Rose. Une des conclusions est que les interactions paramétriques sont peu significatives dans le modèle de détachement par la pluie mais s'avèrent importantes dans le modèle de détachement par le ruissellement

Gävle kommuns VA-huvudman Gästrike Vatten AB ansvarar för dricksvattenproduktionen i Gävle. För Gävles tätort tas vatten från Valboåsen som sträcker sig från öster om staden, genom staden och vidare norrut. Denna rapports syfte är att genom mätning av halten löst syre undersöka Valboåsens förbindelse till Gavleån. Detta kommer ge en ökad förståelse för åsens komplexitet. Resultatet kommer också att användas för att verifiera och utveckla den konceptuella modellen över flödena i åsens grundvattenmagasin som tagits fram av Midvatten AB. För att kunna mäta halten löst syre har en provtagning skett på grundvattenrör. I provtagningen ingick även så kallade slugtest där rörens kapacitet och anslutning till grundvattenmagasinet säkerställdes. Efter mätningen sammanställdes resultatet för att kunna jämföra halten löst syre i grundvattenrören mot den konceptuella modellen. Resultatet visade att halten löst syre i vattnet i de olika grundvattenrören stöder den konceptuella modellen till stora delar och gav även mer information om områden längs åsen där kunskap om flödesförhållandena tidigare var osäkra. Metoden i den utförda studien har visat stor användbarhet för att påvisa flödesförhållanden och ytvattenpåverkan i Valboåsen vilket visar att mätning av syrehalt kan vara mycket användbart i grundvattenutredningar angående ytvattenpåverkan. För att utöka studien av Valboåsen i framtiden behövs mer provtagning i grundvattenmagasinet på områden som inte ingick i denna studie.
Gävle municipality's water company is Gästrike Vatten AB. They manages the drinking water production for the City of Gävle. The production starts in the ridge of Valbo which extends between Överhärde (located in the south part of Valbo) and Strömsbro (located in the north part of Gavle). Purpose of this report is to measure the dissolved oxygen content in the aquifer throughout the whole area to investigate where the infiltration from the nearby Gavle River occurs. The aim of the study is to get a better understanding of the complexity of the Valbo ridge. The measurements will help to verify or modify the conceptual model of the directions of water flow in the Valbo ridge, developed by Midvatten AB. Dissolved oxygen content was measured through ground water pipes. To assess the pipes’ capacity and connection to the aquifer, slug tests were performed. The dissolved oxygen data were analyzed and compared with the conceptual model. The results showed that the dissolved oxygen content in the water supported the conceptual model to a large extent and also gave previously unknown information on some stretches of the ridge. The method shows great potential for additional future studies in Valbo ridge and elsewhere. To expand the study further, a need for more sampling of the aquifer throughout the areas that were not included in this study.

Dans le cadre de la determination des mecanismes du depot chimique en phase vapeur des pyrocarbones laminaires, une etude experimentale a ete conduite. Celle-ci comprend (i) l'analyse de la composition de la phase gazeuse (par spectrometrie infrarouge a transformee de fourier in-situ et par spectrometrie de masse), (ii) l'etude cinetique in-situ de la formation du pyrocarbone (microbalance) et (iii) l'analyse de la structure du carbone depose (microscopie optique en lumiere polarisee et microscopie electronique en transmission). Les parametres experimentaux etudies sont la temperature et le temps de sejour, afin de mettre en evidence l'effet de l'avancement des reactions homogenes (maturation) sur la vitesse de depot et sur la structure du carbone. Les experimentations concernent essentiellement le depot (cvd) dans le cas de la pyrolyse du propane. Cependant d'autres systemes gazeux (benzene, methane / tetrachlorure de carbone) ont egalement ete examines et les aspects lies a l'infiltration (cvi) ont ete pris en compte. Les correlations qui s'etablissent notamment entre les etudes cinetique et structurale realisees avec le precurseur propane, ont conduit a la proposition d'un modele qualitatif qui explique les transitions entre regimes cinetiques et entre types microtexturaux par l'existence de deux voies paralleles pour la formation du pyrocarbone laminaire. Ces deux modes de depot impliqueraient deux familles d'especes gazeuses differentes et meneraient a la formation des deux types de pyrocarbone les plus frequemment rencontres en cvi, a savoir les carbones dits laminaire lisse et laminaire rugueux.

"Conventional" or certified repair procedures for composite structures (i. E. Patches) are usually time-consuming, performed by highly qualified staff and seem immoderate regarding the most common damage found in aeronautics due to low energy impact. A cost-effective and simple repair method based on liquid resin infiltration in the induced crack net is proposed. An analytical model based on damage geometry and physical chemistry properties, is developed to verify the resin infiltration capabilities. An experimental protocol has been developed to identify those properties with conditions similar to the infiltration process (roughness, temperature,. . . ). An experimental set up has been manufactured and different configurations (injection pressure level, infiltration resin toughness. . . ) are studied. Non destructive testing, like ultrasonic inspection, combined to micrographic inspection show good experimental infiltration capabilities. To initiate the validation procedure of this repair, the second part of this work deals with the mechanical behaviour and strength of the repair with experimental tests campaign. Numerical models are used for analysis and understanding. Two different scales are considered at interface (material) and structural level. Fracture Mechanics tests are performed with classical tests such as DCB or ENF, and a new original one, Tensile Flexure test on Notched Specimen (TFNS test), to characterize and identify the repaired interface properties. For their severity regarding composite materials behaviour, both CAI and re-indentation (in-plane and out-of-plane solicitation representative of real loading conditions) were performed on repaired samples. Those complementary tests show that this infiltration repair method restores mechanical properties when proper toughened resins are used

Streszczenie:
Inflow and infiltration (I/I) water in the sewer network originates from groundwater, precipitation, seawater as well as over-leakage from drinking water pipes. It is the proportion of water in the sewer system that is not wastewater and causes problems both at the treatment plant as well as in the sewer network. Through overflows, floods and bypassing at the treatment plant I/I causes discharges of wastewater to recipients and nature and thus have negative environmental effects. I/I also stand for an overload in the system which, in addition to environmental consequences, also has social, economic and technical consequences. Despite efforts to reduce and mitigate the effects of I/I water for a long time, the problem remains and a large proportion of all the wastewater in the network and the treatment plan still is I/I.  Historically, and for many cases at present, there is little to no methodology for how the work with I/I water takes place and is prioritized in the municipalities and responsible water and sewerage organizations. Measures have instead been implemented with a reaction based approach, in other words when something has broken down or there is a failure in the system. A new discussion about I/I water has arisen in recent years due to new requirements from supervisory authorities. As there is not much follow-up or methodology around the work with I/I water, the process of developing a strategy to meet these new requirements for municipalities has shown to be difficult. In cases where analysis of measures against I/I water has been carried out, cost and effects in the treatment plant (i.e. the proportion of I/I water) have most often been used and dimensions other than economic have been left out of the analysis. As I/I water affects social and environmental factors to a great extent, this should be taken into greater account.  In this work, a multi-criterion analysis has been performed in a case study where similar measures to reduce I/I water and its effects in two different areas have been analysed. The included measures were separation, lining, pipe bursting and installation of a stormwater cassette. The results of the case study show that measure A2 has the greatest positive effect. However, there are major uncertainties in the case study conducted and the results are not considered to be robust enough to be used. However, what has been important to include from the work is that by defining and using criteria from all sustainability dimensions, a comprehensive action choice analysis is created and that it is a structured approach to apply. Here, the importance of opening up for discussion within the municipality/organization is emphasized to achieve a coherent view of the prioritization of I/I water and to achieve efficient management. Problems and amounts of I/I water are complex issues and vary from place to place, and are strongly linked to local geohydrological and climate conditions and design of local sewage systems. Therefore, it is important to coordinate the planning of I/I water to use a workflow that is general and can be used, regardless of conditions, in a simple way where adjustments in accordance with local conditions are possible. This work has shown that multi-criteria analysis is a clear and adaptable tool for meeting the difficulties that exist.
Tillskottsvatten härstammar från grundvatten, nederbörd samt havsvatten genom felaktiga anslutningar eller läckage i ledningsnätet samt från överläckage från dricksvattenledningar. Det är andelen av vatten i avloppsnätet som inte är spillvatten och orsakar, genom bräddning, översvämningar och förbiledning i reningsverket, utsläpp av avloppsvatten till recipienter och natur samt står för en överbelastning i systemet. Trots att man arbetat med att minska och lindra effekterna av tillskottsvatten under lång tid så kvarstår problemet och en stor andel av allt samlat vatten i ledningsnätet och som kommer till reningsverket är just tillskottsvatten.  Historiskt, samt för många fall i nuläget, så existerar det lite till ingen metodik kring hur arbetet med tillskottsvatten sker i kommunerna och ansvariga VA-organisationer utan åtgärder har implementerats på måfå eller när något har gått sönder. En ny diskussion kring tillskottsvatten har uppstått de senaste åren på grund av uppkomna nya kravställningar från tillsynsmyndigheter. I och med att det inte finns mycket uppföljning eller metodik kring arbetet med tillskottsvatten så har processen med att ta fram en strategi för att möta dessa nya krav för kommuner ofta varit svår. I de fall som analys av åtgärder mot tillskottsvatten har utförts så har kostnad och effekter i reningsverket (det vill säga andel mängd tillskottsvatten) oftast används och andra dimensioner än ekonomiska har lämnats utanför analysen. Då tillskottsvatten påverkar sociala samt miljömässiga faktorer i hög grad bör detta tas större hänsyn till.  I det här arbetet så har en multikriterieanalys utförts i en fallstudie där liknande åtgärder för att minska tillskottsvatten och dess effekter i olika områden har analyserats. De ingående åtgärderna var separering, infodring, rörspräckning samt anläggning av en dagvattenkassett. Resultatet av fallstudien visar att åtgärdsalternativ 2 har störst positiv effekt. Det finns dock stora osäkerheter i den fallstudie som utförts och resultatet anses inte vara tillräckligt robust för att användas. Det som dock har varit viktigt att ta med från arbetet är att genom att definiera och använda kriterier från alla hållbarhetsdimensioner skapas en heltäckande åtgärdsvalsanalys och att det är ett strukturerat arbetssätt att applicera. Här understryks vikten av att öppna upp för diskussion inom kommunen/organisationen för att nå en sammanhållen syn på prioriteringen av tillskottsvatten samt för att nå en effektiv hantering. Problem och mängder tillskottsvatten i olika ställen är komplext och starkt kopplat till lokala klimat och geohydrologiska förhållanden samt lokala avloppssystem. Därför är det viktigt för att samordna planeringen av tillskottsvatten att använda en arbetsgång som är generell och kan användas, oavsett förutsättningar, på ett enkelt sätt där justeringar i enlighet med lokala förutsättningar är möjligt. Det här arbetet har visat att multikriterieanalys är ett tydligt och anpassningsbart verktyg för att möta de svårigheter som finns.

Abstract Less academic: Terrorist, rebel, and insurgent groups face myriad challenges. Between state repression and fears of infiltration and defeat, it is no surprise they are prone to infighting, instability, and division. And these divisions are meaningful: one led the Islamic State to break from Al Qaeda, and others have perpetually plagued the Irish Republican Army, Palestinian militants, and many more. This book analyzes how armed groups fracture and how splinter groups behave. It is the first to look inside these organizations and to understand the specific disagreements leading fractures to occur. It shows how disagreements are commonly driven by disputes over ideology, leadership, and strategy. Drawing on research from organizational studies to social psychology, and by leveraging analogies from business firms to religious sects, the book shows how these disputes uniquely shape the behavior and survivability of breakaway splinters. When motivated by single, shared disagreement, splinters tend to exhibit higher cohesion, clearer objectives, and greater survivability. And when motivated by strategy in particular, splinters typically attract the most hardline operatives and subsequently adopt increasingly lethal tactics and strategies. The book tests these claims comprehensively. Statistical analyses reveal a clear link between internal disagreements and splinter behavior across countries and over time. Case studies of republican militants in Northern Ireland, Basque militants in Spain, and the Islamic State in Syria and Iraq then confirm these trends. As a result, this book demystifies a complex albeit common event with ramifications for counterinsurgency, counterterrorism, and understanding increasingly fragmented conflicts around the globe. More academic: Armed groups are tenuous organizations. They face difficult environments and uncertain challenges that make instability, division, and organizational fractures common. But when fractures occur, what explains how breakaway groups behave? Drawing on social and group dynamics that afflict everything from political parties to religious sects, this book shows how a splinter group’s trajectory is not predetermined, but is in fact shaped by its motivations for breaking away. Splinters emerging from a single, shared internal disagreement form with clear organizational objectives that attract a highly cohesive base of recruits. This lowers the odds of defection and infiltration, making it easier to decentralize operations and ultimately survive. Armed groups also break apart for a variety of reasons. Ideological, strategic, and leadership disputes each uniquely shape the goals and membership composition of breakaway groups. Strategic disagreements create the most radical splinters since they usually attract dissatisfied hardliners away from the parent. These claims are tested using a mixed-methods research design. Statistical analyses of a new data set reveal strong support for the theory across countries and over time, while in-depth case studies of republican militants in Northern Ireland, Basque militants in Spain, and the Islamic State in Syria and Iraq confirm the theory’s more specific implications. As a result, this book refocuses attention away from external dynamics, like state repression and conciliation, and towards internal dynamics that can better explain how armed groups fragment, operate, and survive.

This chapter analyzes changes in news event coverage. In early 1950, when Sen. Joseph R. McCarthy mounted his virulent attacks accusing the Truman administration of harboring Communists in the State Department, the press simply reported who said what. The Republican Party won the 1952 election and took control of the Senate, and McCarthy became committee chair and expanded his attacks, going after defense industries, universities, and the broadcasters themselves. ABC Television came into national prominence by airing the hearings about supposed Communist infiltration of the U.S. Army, riveting national attention with the live proceedings. But the events could not really speak for themselves, a discovery that seemed to expose a weakness in realism. Every name named exacted a human cost, as McCarthy dragged innocent individuals into the public eye, and his baseless accusations harmed their relationships and destroyed their livelihoods. The consequences, although not lost on the press, were not in themselves news events as then defined.

Through a detailed analysis of ghost tales in the Ashkenazi pietistic work Sefer ḥasidim, this book documents a major transformation in Jewish attitudes and practices regarding the dead and the afterlife that took place between the rabbinic period and medieval times. The book reveals that a huge influx of Germano-Christian beliefs, customs, and fears relating to the dead and the afterlife seeped into medieval Ashkenazi society among both elite and popular groups. In matters of sin, penance, and posthumous punishment, the infiltration of Christian notions was so strong as to effect a radical departure in Pietist thinking from rabbinic thought and to spur outright contradiction of talmudic principles regarding the realm of the hereafter. Although it is primarily a study of the culture of a medieval Jewish enclave, this book demonstrates how seminal beliefs of medieval Christendom and monastic ideals could take root in a society with contrary religious values — even in the realm of doctrinal belief.

AbstractInfiltration into soil slopes is a fundamental concern in civil engineering. Rainfall infiltration leads to changes in pore-water pressure and reduces matric suction in soils, making it one of the main triggers of slope failure (Ali et al. in Comput Geotech 61:341–354, 2014; Wu et al. in Hydro-mechanical analysis of rainfall-induced landslides. Springer, 2020). Slope instabilities caused by water infiltration are called rainfall-induced landslides (Xu and Zhang in Landslides 7:149–156, 2010; Wu et al. in Hydro-mechanical analysis of rainfall-induced landslides.

Metal matrix composites (MMCs) possess superior modulus and strength due to the presence of the reinforce phase in the matrix metal in the form of short or long fibers and particles. Pressure infiltration can produce metal matrix composites containing much high volume fractions of reinforcement in the matrix. This process was recognized as one of the competitive routes to produce near-net shape MMC structures and has achieved successful commercial applications. A transit numerical simulation study is presented for tracking interfaces of two phases for the analysis of pressure infiltrating high-conductivity reinforcement carbon fibers by a molten metal under high-applied pressure conditions. The interface tracking method uses piecewise linear (PLIC) volume-of-fluid (VOF) methods with two-dimensional mesh. The method is coupled with the continuum surface force (CSF) algorithm for surface force modeling, a multi-grid solver support the resolution of large density ratio between the fluid and air. A fine scale infiltration filling flow phenomena between the fibers was solved so that the process parameters can be optimized to cast fibrous MMC engineering structures with fine and pore-free microstructure as well as satisfaction mechanical properties.

The Mo(Si, Al)2-SiC composite was prepared by infiltrating melted aluminum into MoSi2+C compacts at 1350°C, and the microstructure and mechanical property of this composite were analyzed. The results showed that the phases of these composite are Mo(Si1-x, Alx)2 and SiC, and a small amount of Mo5Si3C and Al. Increasing the value of x, the amount of Mo5Si3C and Al phases decrease and even disappear gradually. The microstructure of this composite is sheet-like Mo(Si, Al)2 with needle-like SiC distributed in its gap, and parts of SiC are whisker-like. When x = 0.2, the bending strength of the composite reaches the maximum, which was 770 MPa. The bending strength of designed composite prepared by melt infiltration in this study is better than that of the composite prepared by hot pressing reported in literature.

Abstract The most common way of transportation for refined oil is long-distance pipeline. Pipeline accidents occur frequently due to corrosion, equipment failure, external forces destruction. Aiming at predicting the contaminated area in soil caused by products pipeline accidents, this experimental study was conducted to examine the relationship between the light non-aqueous phase liquids (LNAPL) accumulative infiltrate volume and the time of infiltration process in homogeneous and layered soils. The soil’s hydraulic parameters were obtained by basic experiments and RETC software. Compared with traditional infiltration mathematical model, Green-Ampt model is the most common mathematical model to calculate the infiltration process in the unsaturated soil. In this study, a modified Green-Ampt model was developed to describe water and diesel infiltration through a 100-cm-long and layered soil column. In the modified Green-Ampt model, an infiltration reduction ratio was introduced to describe the effect of the hydraulic conductivity of the layered position. To evaluate the proposed method in the effect of the layers position infiltration permeability, eight constant water head layered column infiltration experiment were conducted to record the different infiltration fluid and different constant water head infiltration process. Compared the experiment results with traditional mathematical traditional Green-Ampt model (average R2 = 0.976) and Hydrus-1D software (average R2 = 0.988) The modified Green-Ampt model had relatively higher precision in accumulative infiltrate volume (average R2 = 0.992) and the wetting front velocity in infiltration process (average R2 = 0.997). Thus, the modified mathematical model was applied an effective upscaling scheme in layered formations. The experimental result also demonstrated that soil layering affected the infiltration process. With the increase of soil depth and density, the infiltration speed of the layered soil column decreased. Additionally, the infiltrate speed of wetting front decreases slowly at the layered surface. The experiment’s fitting results showed that the modified mathematical model about infiltrate time and liquid contaminant accumulative infiltrate volume, wetting front infiltrate velocity can highly effective approach to simulate water and light non-aqueous phase liquids (LNAPL) infiltration process in layered soils.

Selective Laser Sintering (SLS) is tooless, computer-controlled layerwise additive manufacturing using a laser and a powder bed. The scanning laser locally melts the surface of a powder bed selectively, followed by deposition of a fresh layer of powder and repetition of the process. SLS has been developed for plastic powder. Creation of non-metallics and metal parts is more challenging. One approach is to mix the master powder with a transient binder. SLS melts the binder which wets the master powder, creating a green part. Subsequent post-processing is required to either remove the binder or convert it to a usable form. The last step is infiltration with a molten substance. Fundamentals of infiltration theory will be reviewed. A study of dimensional changes associated with various stages of processing reveals that overall linear dimensions vary less than one percent compared to the computer solid model. Several examples demonstrating the utility of an infiltration approach to freeform fabrication will be presented. These include silicon carbide with a phenolic binder, infiltrated with silicon; graphite with a phenolic binder infiltrated with epoxy; and tool steel with a proprietary low-ash binder infiltrated with cast iron.

This work analyzes the infiltration behavior of water into sub-nanometer MFI zeolite pores using molecular dynamics simulations. Infiltration simulations are run for a range of partial charge values on the zeolite atoms. Infiltration behavior is compared to partial charges to verify dependence and determine critical charge above which infiltration becomes severely inhibited even at high pressures. Attraction energy is calculated and correlated to the observed infiltration behavior. The critical partial charge of Si∼1.8 occurs when the water-zeolite interaction energy becomes stronger than water-water attraction due to which water molecules get stuck and infiltration is significantly reduced.

Review question / Objective: This systematic review and meta-analysis aimed to assess the impact of fatty pancreas on postoperative pancreatic fistula (POPF) after pancreaticoduodenectomy (PD). Condition being studied: Postoperative pancreatic fistula (POPF) is a major complication and its most frequently reported risk factors tend to be anatomic features of the pancreatic remnant, such as a soft pancreatic texture. They hypothesized that fat infiltration intuitively increases the softness of the gland, and therefore, might be a risk factor of POPF development. Therefore, the percentage of fatty infiltration of the pancreas constituting a risk for POPF after PD still needs to be defined.

Streszczenie:
The objective of this one-year project was to show whether a significant correlation can be established between the decreasing infiltration rate of the soil, during simulated rainstorm, and a following increase in the reflectance of the crusting soil. The project was supposed to be conducted under laboratory conditions, using at least three types of soils from each country. The general goal of this work was to develop a method for measuring the soil infiltration rate in-situ, solely from the reflectance readings, using a spectrometer. Loss of rain and irrigation water from cultivated fields is a matter of great concern, especially in arid, semi-arid regions, e.g. much of Israel and vast area in US, where water is a limiting factor for crop production. A major reason for runoff of rain and overhead irrigation water is the structural crust that is generated over a bare soils surface during rainfall or overhead irrigation events and reduces its infiltration rate (IR), considerably. IR data is essential for predicting the amount of percolating rainwater and runoff. Available information on in situ infiltration rate and crust strength is necessary for the farmers to consider: when it is necessary to cultivate for breaking the soil crust, crust strength and seedlings emergence, precision farming, etc. To date, soil IR is measured in the laboratory and in small-scale field plots, using rainfall simulators. This method is tedious and consumes considerable resources. Therefore, an available, non-destructive-in situ methods for soil IR and soil crusting levels evaluations, are essential for the verification of infiltration and runoff models and the evaluation of the amount of available water in the soil. In this research, soil samples from the US and Israel were subjected to simulated rainstorms of increasing levels of cumulative energies, during which IR (crusting levels) were measured. The soils from the US were studied simultaneously in the US and in Israel in order to compare the effect of the methodology on the results. The soil surface reflectance was remotely measured, using laboratory and portable spectrometers in the VIS-NIR and SWIR spectral region (0.4-2.5mm). A correlation coefficient spectra in which the wavelength, consisting of the higher correlation, was selected to hold the highest linear correlation between the spectroscopy and the infiltration rate. There does not appear to be a single wavelength that will be best for all soils. The results with the six soils in both countries indeed showed that there is a significant correlation between the infiltration rate of crusted soils and their reflectance values. Regarding the wavelength with the highest correlation for each soil, it is likely that either a combined analysis with more then one wavelength or several "best" wavelengths will be found that will provide useful data on soil surface condition and infiltration rate. The product of this work will serve as a model for predicting infiltration rate and crusting levels solely from the reflectance readings. Developing the aforementioned methodologies will allow increased utilization of rain and irrigation water, reduced runoff, floods and soil erosion hazards, reduced seedlings emergence problems and increased plants stand and yields.
