Interpretacja aktywności w kontekście teorii stresu wydaje się kompleksowa i dobrze opisująca zjawiska zachodzące w organizmie. Jednym z problemów treningu fizycznego nie tylko 20-30 letniego ale i 60-70 letniego człowieka jest wybór właściwego pod względem objętości, intensywności i specyfiki obciążenia oraz właściwej formy i czasu wypoczynku.

The interpretation of physical activity in light of stress theory seems comprehensive and well suited to describe the processes taking place within the human body. One of the problems inherent in physical training, and encountered not only by the individuals in their twenties or thirties but also in their sixties and seventies, is the choice of a proper – in terms of volume, intensity and specificity – exercise load as well as form and time of rest. The aim of the present study is to determine individual time frames of the early and late restitution and supercompensation phase after endurance effort in a man in his sixties. A case study. Material and methods. The studied male individual who lives a healthy life-style subjected himself to the markings of 46 selected blood indicators conducted after endurance effort in the spontaneous restitution phase. Results. Positive results were observed in most of the blood features. However, their configuration within the 5-day measurement cycle varied and thus allowed one to determine both the early and late restitution and supercompensation phase. Conclusions. (1) In a man in his sixties the first (fast) restitution phase after endurance effort ends, depending on the analysed blood feature, in the first, second or third hour after finished effort; the second phase (slow), as observed in many of the measured blood features, ends 45 minutes after finished effort. (2) Based on the analyzed blood features, however, one cannot unambiguously determine the time occurrence of supercompensation phase; nevertheless, one may assume that for the studied individual it occurs thirty-three hour after finished effort. (3) In order to more accurately determine time frames of the early and late restitution, the research on a relatively larger population of varied sex and age is required; such a research would have to be conducted both before and after the physical efforts and it would have to engage various motoric functions of the studied individuals.

Wypoczynek rozumieniu fizjologicznym jest dynamicznie zmiennym stanem ustroju, następującym bezpośrednio po zakończeniu bądź też zmniejszeniu intensywności wysiłku fizycznego lub umysłowego. W tym okresie dominują procesy asymilacyjne nad dysymilacyjnymi. Spadek wydolności fizycznej w starszym wieku należy tłumaczyć pogorszeniem stopnia perfuzji mięśni podczas wysiłku. Jego przyczyn należy upatrywać w anatomicznych zmianach zachodzących zarówno w mięśniu sercowym, jak i w naczyniach krwionośnych.

W okresie restytucji późnej: saturacja tlenowa, ciśnienie parcjalne tlenu. Należy przyjąć, że wskaźnik aktualnego nadmiaru zasad i stężenia jonów wodorowęglanowych wymaga dłuższego okresu normalizacji niż 54 godzina restytucji późnej. <strong>Abstract</strong> Introduction. Rest meaning is dynamically variable physiological state of the body, immediately following the completion or reducing the intensity of physical or mental. During this period, dominated by the processes of assimilation over dissimilation. The decline of physical performance in older extent be explained by the deterioration of muscle perfusion during exercise. Its causes should be sought in anatomical changes occurring both in the myocardium, as well as blood vessels. The aim of the study is to demonstrate the changes in selected indicators and characteristics of blood gases during the period of physiological restitution after exercise endurance for a man in 6 decade of life. Materials and methods. Tested man pursuing a healthy lifestyle surrendered to the designation of selected indicators of blood after exercise endurance during spontaneous restitution pH, PCO<sub>2</sub>, PO<sub>2</sub>, BB, BE, BE<sub>art</sub>, cHCO<sub>3</sub>, SO<sub>2</sub>(c). Obtained results. Positive results were observed in most measured rates and characteristics of blood gases. At the same time differently they presented their configuration during the 5-day measurement cycle. The most positive changes were observed in the size of BB, BE, PCO<sub>2</sub>. Conclusions 1. During the early restitution after exercise endurance in a 61 year old male normalization is: systolic and diastolic arterial blood pressure, heart rate, the partial pressure of carbon dioxide, the principle of buffering plasma, state principles (excess / deficiency). In the late restitution: oxygen saturation, partial pressure of oxygen. 2. It is assumed that the current rate of excess bases and bicarbonate ion concentration requires a longer period of normalization than 54 hours restitution of late.

The treatment of heart failure (HF) is challenging and morbidity and mortality are high. The goal of this study was to determine if inhibition of the late Na+ current with ranolazine during early hypertensive heart disease might slow or stop disease progression. Spontaneously hypertensive rats (aged 7 mo) were subjected to echocardiographic study and then fed either control chow (CON) or chow containing 0.5% ranolazine (RAN) for 3 mo. Animals were then restudied, and each heart was removed for measurements of t-tubule organization and Ca2+ transients using confocal microscopy of the intact heart. RAN halted left ventricular hypertrophy as determined from both echocardiographic and cell dimension (length but not width) measurements. RAN reduced the number of myocytes with t-tubule disruption and the proportion of myocytes with defects in intracellular Ca2+ cycling. RAN also prevented the slowing of the rate of restitution of Ca2+ release and the increased vulnerability to rate-induced Ca2+ alternans. Differences between CON- and RAN-treated animals were not a result of different expression levels of voltage-dependent Ca2+ channel 1.2, sarco(endo)plasmic reticulum Ca2+-ATPase 2a, ryanodine receptor type 2, Na+/Ca2+ exchanger-1, or voltage-gated Na+ channel 1.5. Furthermore, myocytes with defective Ca2+ transients in CON rats showed improved Ca2+ cycling immediately upon acute exposure to RAN. Increased late Na+ current likely plays a role in the progression of cardiac hypertrophy, a key pathological step in the development of HF. Early, chronic inhibition of this current slows both hypertrophy and development of ultrastructural and physiological defects associated with the progression to HF.

Full textAbstract:
Premature beats can trigger ventricular arrhythmias in heart disease, but the mechanisms are not well defined. We studied the effect of premature beats on activation and repolarization dispersion in seven patients with cardiomyopathy (57 ± 10 yr, left ventricular ejection fraction 31 ± 7%). Activation time (AT), activation-recovery interval (ARI), and total repolarization time (TRT) were measured from 26 unipolar electrograms during right ventricle (RV) endocardial (early) to left ventricle epicardial (late) activation in response to RV apical extrastimulation (S1S2). Early TRT dispersion increased significantly with shorter S1S2 (1.0 ± 0.2 to 2.3 ± 0.4 ms/mm, P < 0.0001), with minimal change in late TRT dispersion (0.8 ± 0.1 to 1.0 ± 0.3 ms, P = 0.02). This was associated with an increase in early AT dispersion (1.0 ± 0.1 to 1.5 ± 0.2 ms/mm, P = 0.05) but no change in late AT dispersion (0.6 ± 0.1 to 0.7 ± 0.2 ms/mm, P = 0.4). Early and late ARI dispersion did not change with shorter S1S2. AT restitution slopes were similar between early and late sites, as was slope heterogeneity. ARI restitution slope was greater in early vs. late sites (1.3 ± 0.6 vs. 0.8 ± 0.6, P = 0.03), but slope heterogeneity was similar. With shorter S1S2, AT-ARI slopes became less negative (flattened) at both early (−0.4 ± 0.1 to +0.04 ± 0.2) and late (−1.5 ± 0.2 to +0.3 ± 0.2) sites, implying less activation-repolarization coupling. There was no difference in AT-ARI slopes between early and late sites at short S1S2. In conclusion, high-risk patients with cardiomyopathy have greater TRT dispersion at tightly coupled S1S2 due to greater AT dispersion and activation-repolarization uncoupling. Modulated dispersion is more pronounced at early vs. late activated sites, which may predispose to reentrant ventricular arrhythmias.

Transgenic mice have been increasingly utilized to investigate the molecular mechanisms of cardiac arrhythmias, yet the rate dependence of the murine action potential duration and the electrical restitution curve (ERC) remain undefined. In the present study, 21 isolated, Langendorff-perfused, and atrioventricular node-ablated mouse hearts were studied. Left ventricular and left atrial action potentials were recorded using a validated miniaturized monophasic action potential probe. Murine action potentials (AP) were measured at 30, 50, 70, and 90% repolarization (APD30–APD90) during steady-state pacing and varied coupling intervals to determine ERCs. Murine APD showed rate adaptation as well as restitution properties. The ERC time course differed dramatically between early and late repolarization: APD30 shortened with increasing S1–S2 intervals, whereas APD90 was prolonged. When fitted with a monoexponential function, APD30 reached plateau values significantly faster than APD90 (τ = 29 ± 2 vs. 78 ± 6 ms, P < 0.01, n = 12). The slope of early APD90 restitution was significantly <1 (0.16 ± 0.02). Atrial myocardium had shorter final repolarization and significantly faster ERCs that were shifted leftward compared with ventricular myocardium. Recovery kinetics of intracellular Ca2+ transients recorded from isolated ventricular myocytes at 37°C (τ = 93 ± 4 ms, n = 18) resembled the APD90 ERC kinetics. We conclude that mouse myocardium shows AP cycle length dependence and electrical restitution properties that are surprisingly similar to those of larger mammals and humans.

Full textAbstract:
AbstractCultural restitution in international law typically aims to restore cultural property to the state of origin. The experience of World War II raised the question of how to adapt this framework to deal with states that persecuted cultural groups within their own borders. Nazi Germany’s persecution of Jews and its attempt to destroy their cultural heritage began before the war and was carried out systematically throughout the war in the conquered territories. After the war, the Polish Jewish lawyer Raphael Lemkin advocated for the recognition of the new crime of genocide and, in particular, its cultural dimensions. Jewish organizations also argued that cultural destruction should be seen as an integral component of the crime of genocide and that the remedy of cultural restitution should be part of the effort to rehabilitate the injured group, but their efforts to gain recognition in the International Military Tribunal in Nuremberg for the unique harm suffered by the Jews were unsuccessful. This article discusses an innovative approach developed by Jewish jurists and scholars in the late 1940s and 1950s, according to which heirless cultural property was returned to Jewish organizations as trustees for the Jewish people. Though largely forgotten in the annals of law, this approach offers a promising model for international law to overcome its statist bias and recognize the critical importance of cultural heritage for the rehabilitation of (non-state) victim groups.

Background: Common airway management strategies during cardiopulmonary resuscitation are bag- mask-valve ventilation followed by endotracheal intubation. Timing of endotracheal intubation is controversial. This study was designed to compare the effect of early vs late endotracheal intubation in terms of return of spontaneous circulation.Methods: This is an observational retrospective study done at tertiary center for the period of two years. The study population was inpatient, adult and pediatric with witnessed cardiac arrest in whom airway management was initially done with bag-valve-mask ventilation followed by endotracheal intubation. Timing of intubations were grouped into early and late with cut off time of five minutes and the groups were compared in terms of return of spontaneous circulation.Results: There were total of 193 patients included in the study. Early intubation was done in 114 patients (59.06%) and late intubation was done in 79 patients (40.94%). Mean time for early intubation was 3.11 minutes. Mean time for late intubation was 7.89 minutes. Seventy three patients (37.8%) attained sustained ROSC. Thirty five patients (30.7%) achieved ROSC in early intubation group while 38 patients (48.1%) attained sustained ROSC in late intubation group(p = 0.016). Conclusions: Early intubation during cardiopulmonary resuscitation was associated with lower rate of return of spontaneous circulation.

PurposeThe aim of the study was a review of the literature in order to evaluate the results and complications of closed reduction in late-detected developmental dysplasia of the hip (DDH).MethodsThis study consisted of an analysis of the literature relative to late-detected DDH treatment options considering hip congruency, rates of re-dislocation and of avascular necrosis.ResultsGradual closed reduction (Petit-Morel method) appears to be an effective method concerning joint congruency restitution. Dislocation relapse and avascular necrosis are more efficiently prevented with closed versus open reduction. The tendency for spontaneous correction of acetabular dysplasia decreases if closed reduction is performed after 18 months of age. Patient age at the beginning of traction should be considered for the prognosis, with a lower rate of satisfactory results showing after the age of 3 years.ConclusionIn our opinion, the Petit-Morel method is a suitable treatment option for children aged between six months and three years with idiopathic DDH.

Aim. To study the perinatal outcomes of women, living in the Khatlon region with late spontaneous preterm birth (LSPB).Material and methods. 146 women with late spontaneous preterm birth were studied, according to the gestational age at which the birth occurred: subgroup A - gestational age 34 weeks + 6 days (27 women), subgroup B - gestational age 35 weeks + 6 days (51 women), subgroup B – gestational period 36 weeks + 6 days (68 women). Parametric and nonparametric methods of biological statistics (Student and Whitney-Munny tests).Results. One in five newborns born to mothers with late spontaneous preterm labour was found to be small for gestational age, with fetal growth restriction diagnosed in 75.8% of these cases. A statistically significant reduction in mean Apgar scores at 1 and 5 minutes was observed in neonates born at 34+6 weeks’ gestation. Respiratory failure was the cause of early neonatal mortality in 56.3% of cases. In the structure of early neonatal morbidity, respiratory failure is a leading cause, with its frequency and severity depending on gestational age. A strong inverse correlation was found between gestational age and the incidence of respiratory failure in the early neonatal period in neonates born to mothers with late spontaneous preterm labour and fetal growth restriction.Conclusion. It is advisable to further conduct research on the effectiveness of differentiated approaches to preventing respiratory distress syndrome in late preterm birth.

Full textAbstract:
This chapter explores the historical evolution of contextual voicing neutralization in Maltese obstruents, focusing on regressive voicing assimilation and word-final devoicing. By comparing Modern Maltese with its Arabic ancestor, evidence shows sporadic instances of spontaneous voicing and devoicing in earlier stages, transitioning to systematic phonological rules by the late 18th century. An analysis of texts, lexicons, and notarial records from the 15th to 18th centuries reveals that while early Maltese exhibited voiced obstruents and mixed clusters, regressive assimilation and word-final devoicing gradually became pervasive. Both rules, first attested in the 16th century, spread via lexical diffusion, affecting Semitic roots and Romance loanwords alike. The study underscores the typological shift from unrestricted obstruent voicing contrasts in Arabic to the Maltese system characterized by regressive assimilation and word-final devoicing. This development challenges claims of direct inheritance from Sicilian Arabic, suggesting instead a Maltese-specific innovation. Despite some exceptions, such as non-integrated borrowings, these phonological rules persist synchronically in Modern Maltese. The findings contribute to understanding the diachronic phonology of Maltese, highlighting its divergence from other Arabic varieties and its typological realignment. The study also emphasizes the importance of historical linguistic evidence in reconstructing phonological change and its implications for the interaction of Semitic and Romance components in Maltese.

Abstract When using triptans to treat migraine attacks it is important to ensure accurate timing of triptan intake. Early intake and late intake of triptans will both result in unsatisfactory treatment results. If the triptan is taken too early it may be unnecessary or inefficient, because the headache might show a spontaneous remission or might only develop into a tension-type headache. Patients with frequent migraine attacks may develop drug-induced headache as a result of overfrequent intake. On the other hand, if the triptan is taken too late it may not act fast enough or the results may be unsatisfactory1–3. Many patients with frequent headaches suffer both from migraine and from tension-type headaches; here, too, it is important to know the right time to take the triptan.

Germany invaded France in 1940. A month later the countries entered into an agreement, by which 80 percent of France was occupied by Nazi Germany. Competing property expropriation laws were enacted in both Occupied and Unoccupied (Vichy) France. More than 20 percent of France’s Jewish population was killed during World War II. Restitution and reparations measures—particularly with respect to private and heirless property—took place in two phases. The first occurred in the immediate postwar years and ended around 1954, and the second commenced in the late 1990s and early 2000s and is ongoing. In the late 1990s, a government commission (Matteoli Commission) was established to examine the conditions under which property was confiscated by the occupying or Vichy regimes. A compensation commission (Drai Commission) was subsequently established to provide payment to those not previously compensated for damages resulting from legislation passed either by the occupying or Vichy regimes. France endorsed the Terezin Declaration in 2009 and the Guidelines and Best Practices in 2010.

Abstract This chapter explores a forty-year lull in art restitution claims, and the factors in a revival of claims in the mid-1990s. Case studies of legal disputes over works in the French and Dutch custodianships at the end of the century illustrate a shift in cultural property norms, particularly regarding wartime sales under duress. Among the three countries, the Dutch government was the most proactive in carrying out provenance research on works still held by the state by the early 2000s. After limited progress through the late 2010s, the French government finally launched a more robust research program in 2019. The Belgian government was least transparent and proactive during this time, and amid research and repatriation debates over colonial collections, expressed a commitment to pursuing research on works in the custodianship in 2022.

Abstract Works written about the Young Turk movement, whether by its members or their contemporaries,2 all confirm a particular point: the movement was a link in the historical chain of Ottoman westernization and bureaucratic modernization and represented the modernist wing of the Ottoman intelligentsia and bureaucracy. However, it is difficult to find any evidence of these connections in relevant scholarly studies published since 1945. Nevertheless, the Young Turk and westernization movements were indisputably intertwined, and the latter, starting as early as the late eighteenth century, played an undeniable role in shaping the Young Turk Weltanschauung.In a book written nearly fifty years after the onset of the Ottoman westernization movement, the following question was posed: “Was the gravitation toward western ways precipitated by spontaneous attraction, or was it the fruit of wise counsel and foresight by Ottoman statesmen?” Undeniably both elements propelled westernization, and although it was initially a spontaneous development, it soon became the policy of Ottoman statesmen. After the Ottomans’ humiliating defeats by western powers, self-doubt and questioning became the order of the day. Initially, Ottoman intellectuals promoted their conclusion that Ottomans had been overcome by “infidels” who had mastered the “new technology.”

Full textAbstract:
This chapter focuses on Type 2 (lexical aspectual) compound verbs, which appear to occupy a unique position in the systems of V-V complexes in Asian languages because they make up lexical combinations with desemanticized verbs in V2. Based on diachronic data, it is suggested that this marked class of compound verbs arose in Late Middle or Early Modern Japanese via two paths: (i) reanalysis and lexicalization of aspectual auxiliary constructions in Old and Early Middle Japanese and (ii) constructionalization of a special compounding schema where V2 specifies the manner and other adverbial meanings of V1. The latter path is characterized by the desemanticization of V2s in Type 1 thematic compounds or by spontaneous coinage of new V2s with adverbial meanings. The multifaceted development of Type 2 compounds, which does not readily fit in with the standard view of item-by-item grammaticalization, presents a motivation for viewing grammaticalization as creation of a novel morphological construction.

Abstract This chapter discusses the evolutionary origins of the vulnerabilities that permit aging, cancer, and metastasis; the history that generated human genetic diversity in disease and drug response; the evolutionary forces that shaped the human life history; the concepts needed to understand plastic responses to environmental differences; and notable aspects of the human life history, including oocytic atresia, selective spontaneous abortions, and menopause. The sick person that a doctor tries to treat has an evolutionary history that has produced vulnerabilities, some with known origins, and genes whose variation has consequences for disease risk and drug response. That person also has a developmental history in which early life events have influenced the risks of late life disease. The evolutionary privileging of the reproductive success of genes over the survival of individuals has produced vulnerabilities that make us susceptible to disease and aging.

This chapter explores how hitchhiking—with its promise of free, untethered, and spontaneous mobility—allowed youths of the late sixties and early seventies the ability to maintain a largely nomadic existence while living out the values of the hippie (or freak, as many self-identified) lifestyle. Within the national culture soliciting rides became closely connected to an increasingly politicized counterculture—one that sought to upend the Protestant work ethic and conventional sexual and gender norms. Notably, this radicalized youth culture and its dismissal of traditional values generated resentment among many, creating a deep cultural divide between young people and older, so-called straight Americans. Because of its association with the freak movement, the act of hitchhiking became a key point of confrontation. An increasingly mature regulatory state began cracking down on the practice, in part to reign in the counterculture and women’s liberation movement, but also to promote safer and more uniform traffic behavior. Still, these efforts did little to slow the growing popularity of the practice in the early 1970s.

This chapter presents digital forms of anthropological restitution developed in the late 1990’s and early 2000 by Barbara Glowczewski with different Aboriginal peoples for their own use and a larger audience. She designed the CD-ROM Dream Trackers (Yapa Art and Knowledge of the Australian Desert published by Unesco) with 51 elders and artists from the Central Australian community of Lajamanu in the Northern Territory. Quest in Aboriginal Land is an interactive DVD based on films by Indigenous filmmaker Wayne Barker, juxtaposing four regions of Australia. Both projects aimed to explore and enhance the cultural foundations of the reticular way in which many Indigenous people in Australia map their knowledge and experience of the world in a geographical virtual web of narratives, images and performances. The relevance of games for anthropological insights is also discussed in the paper. Reticular or network thinking, Glowczewski argues, is a very ancient Indigenous practice but it gains today a striking actuality thanks to the fact that our so-called scientific perception of cognition, virtuality and social performance has changed through the use of new technologies.

Abstract We investigated countercurrent spontaneous imbibition (COUCSI) of water displacing oil in a 1D linear system with one side open, and one side closed. The Physics-Informed Neural Networks (PINNs) technique was used to estimate saturation profiles along the core and recovery against time; based on the same input information as a reservoir simulator. We demonstrate the usefulness of Change-of-Variables as an approach to improve PINN solutions. The problem was first normalized, where only a saturation-dependent diffusion coefficient results in different solutions. The initial condition was zero saturation, the open boundary had a saturation equal to one, and the closed boundary had a zero saturation gradient. We formulated the problem in three equivalent ways by Change-of-Variables: XT, YZ, and Z formulations. The first is the original normalized form and describes saturation as a function of normalized position X and time T. The second defines saturation as a function of Z=X/T^0.5 and Y=T^0.5. The third considers saturation as a sole function of Z=X/T^0.5 and is valid only at early times (ET), before water meets the no-flow boundary. The COUCSI problem was solved using a feed-forward neural network trained based on a weighted loss, including the physics-informed loss term and terms corresponding to initial and boundary conditions for all the formulations. No synthetical or experimental data were involved in the training. The generalization ability is tested by applying the workflow to two imbibition cases with different displacement profile behavior. The PINN solutions were tracked to determine if they followed the flow's theoretical properties, including self-similarity, square root of time behavior, and Total Variation (TV). We investigated the ability of the applied formulations to estimate the correct solution (compared to numerical simulations) at early and late times. All the formulations could very closely converge to the correct solutions, with the water saturation mean absolute errors around 3.5 and 2.5 percent for XT and YZ formulations and 1.0 percent for the Z formulation at ET. The Z formulation almost perfectly captured the self-similarity properties of the system in the ET period (and in lower level, YZ), which only depends on X/T^0.5 at early time. The TV of saturation was successfully preserved in the Z formulation and YZ performed better than XT formulation. By performing a sensitivity analysis we demonstrate that Change-of-Variables can lead to a lower number of required collocation points and also smaller network sizes.

Abstract Solutions are presented to predict 1D counter-current spontaneous imbibition oil recovery at early and late times, i.e. before and after the imbibing water reaches the noflow boundary based on knowing the capillary diffusion coefficient. The system is presented in a normalized form where the space, time and saturation variables are scaled. The normalized capillary diffusion coefficient (NCDC) has an area of 1 when integrated over the saturation range with positive capillary pressure (where spontaneous imbibition occurs). The scaled solution of the system hence only depends on the shape of the NCDC function and not its magnitude (which by definition has an area of 1). Based on the semi-analytical solution by McWhorter and Sunada (1990) scaled recovery equals the square root of scaled time for early times. The time scale depends on one part τ related to known constants, and a part Tch related to the NCDC shape. The normalized critical time Tn,cr when the square root regime ends is known exactly from this solution. Recovery thereafter depends on the NCDC and must be calculated numerically. A dataset is generated based on combining 1000 sets of relative permeabilities and capillary pressure functions with mixed-wet to strongly water-wet states and end point mobility ratios into corresponding NCDCs. Recovery is studied in terms of how long the early square root of time behavior lasts, what the imbibition rate coefficient is in that period, and how recovery changes at late time. The former lasts longer than Tn,cr in practice and is instead characterized by a transition time Tn,tr. The parameters Tch, Tn,tr are well correlated with the CDNC shape, as quantified by one or two fractions zα,β denoting the fraction of the NCDC between normalized saturations α and β. Late time recovery was modeled using an extended Arps type decline curve where one parameter r was correlated with zα,β. We thus find relations between the shape of the NCDC and the behavior of the solution at early and late times. Next we interpret recovery data to estimate the absolute capillary diffusion coefficient. This is done by systematically determining RFtr and the Arps parameter from tuning or type curves and linking them to associated NCDC fractions zα,β. The methods are illustrated using literature experimental data. The predicted NCDCs could predict the original recovery curves. It was found that systems with high non-wetting phase mobility and strong water-wetness are likely to have most of the recovery occur as proportional to the square root of time.

In this paper, we present our interpretation for some of the unexpected experimental results that we obtained during 3D spontaneous imbibition experiments. We treated carbonate rocks with flourochemical polymers where we altered the wettability towards reduced liquid-wetting. The expected result is a reduced imbibition rate as a result of reduced capillary forces. Although the early imbibition rate decreased, we observed an increase in rate at late imbibition time resulting in a higher liquid saturation in the altered rock. We used numerical modeling to interpret the result and show that this observation actually represents the target wettability state we should be seeking in some applications.

Full textAbstract:
Abstract This paper investigates the phenomenon of anomalous imbibition in shale reservoir rocks through a combination of numerical and experimental approaches. Shale gas reservoirs present unique challenges due to their low permeability and complex pore structure, significantly influencing fluid transport mechanisms. Spontaneous imbibition, where water (or fracturing fluids) infiltrates the shale matrix and displaces the gas driven by capillary force, plays a critical role in the recovery efficiency of shale gas reservoirs. Fluid spontaneous imbibition in heterogeneous porous media, such as tight and shale formations, often exhibits anomalous behavior dominated by multiple time-spatial scales. Based on direct experimental evidence of anomalous imbibition process, this work proposes a fractional derivative model to quantitatively analyze the complete early-to-late time dynamics of the anomalous imbibition in shale gas reservoirs. Prior research on the anomalous imbibition process has primarily focused on fractal models and has compared results with indirect indicators, such as the cumulative imbibed volume derived from imbibition experiments. This study introduces direct observations and quantifications of the anomalous imbibition dynamics, utilizing saturation distributions converted from Computed Tomography (CT) numbers. A fractional diffusion model is proposed, and the resulting non-linear fractional differential equations are solved numerically using the finite-difference method. The proposed model solution accurately captures the complete early-to-late time behavior of cumulative recovery volume and the wetting phase front propagations which exhibit anomalous phenomena.

<div class="section abstract"><div class="htmlview paragraph">There is little prior research into chain-collisions, despite their relatively large contribution to injury and harm in motor-vehicle collisions. This study conducted a series of rear-impact, front-impact, and chain-collision impacts using a bumper car ride at an active amusement park as a proxy for automobiles. The purpose was to begin to identify the threshold time range when separate, discrete collisions transition into a hybrid or combined chain-collision mode and provide bases for future analyses. The test series consisted of rear impacts into an occupied target vehicle from a driven bullet vehicle; frontal impacts into a perimeter barrier (wall); chain-collisions consisting of a driven bullet vehicle striking an occupied primary target vehicle, which then collided with a non-occupied secondary target vehicle; and chain-collisions consisting of a driven bullet vehicle striking an occupied primary target vehicle which then collided with a wall. Time between collisions was adjusted via spacing. Vehicle impact velocities, changes in velocity (delta-Vs), accelerations, and coefficients of restitution are reported. Head and extremity excursions of the restrained occupant of the primary target vehicle were also tracked using high-speed video recording. The results show that chain-collisions exhibited three phases: an early phase that occurs during the initial rearward occupant excursion, a middle phase that occurs during the forward rebound occupant excursion, and a late phase that occurs while the occupant is recovering back to the initial position. The first phase appears to last for approximately 150 ms, the middle phase for approximately 50 to 75 ms, and the late phase from thereafter until approximately 400 ms to 500 ms after the initial collision. The middle phase appears to be related to the timing of the occupant’s return to their original position and their maximum rebound velocity and the late phase to the remaining occupant displacement but not velocity. Overall, occupant and vehicle kinematics during a chain-collision were different from those of the individual component collisions and were different from a superposition of the component collisions. This is the first reporting of these phases in a chain-collision.</div></div>

The efficacy of intravenous streptokinase on recanalization of the 'infarct vessel' and its effect on left ventricular function was assessed in two groups of patients. Group I consisted of 90 consecutive patients (age 32-75 years, mean 56 years) received 500,000 units of intravenous streptokinase (STK) over 30 minutes within 6 hours of onset of acute myocardial infarction (MI). Forty-eight patients had anterior MI and forty-two had inferior MI. The control group consisted of forty survivors of acute MI comparable in age and site of infarction. In Group I, ten patients were administered STK after baseline coronary angiogram demonstrated total occlusion of infarct related coronary artery. In these patients, serial coronary angiogram were done at intervals of 30 minutes after STK infusion upto a period of 3 hours. Recanalization was seen in all cases within 75-135 minutes (average 120 minutes). Seventy-nine of STK group and all of the control group underwent selective coronary arteriography and contrast left ventriculography within 48 to 72 hours of acute MI. Recanalization of infarct related artery was demonstrated in 72 out of 79 patients (91%) in STK group while 8 (20%) in control group had spontaneous recanalization. Left ventricular ejection fraction (LVEF) was higher in STK group (58%) as compared to control group (49%). Among patients with anterior MI, LVEF was significantly better in STK compared to control group (59% Vs. 44%, p > 0.01)while in inferior MI the difference was not significant (63% Vs. 59.4%, p > 0.05) in the two groups. Follow up study in 20 STK patients at 6 months revealed a decrease in residual stenosis from 75 ± 8% to 60 ± 6% and improvement in LVEF from 59 ± 8% to 68 ± 12% (p > 0.01). In conclusion, intravenous STK in acute MI results in high rate of infarct vessel patency and improved global left ventricular function during both early and late follow up period.

Introduction: Puerperal mastitis is an inflammatory process of the mammary gland that affects women during lactation, due to stasis in the mammary ducts. The clinical findings vary from focal inflammation to abscesses when not treated early. Additional complications may arise, such as tissue loss by necrosis, leading to the appearance of opportunistic diseases. Myiasis consists of appearance of fly larvae in these tissues, a rare condition in humans. When in cutaneomucosal area, there are complaints of intense pruritus and local pain. The authors seeked to correlate the clinical aspects of puerperal mastitis with breast involvement by myiasis, aiming at the importance of early management and treatment of these pathologies. Case report: A 23-year-old patient, GIV PIII, was admitted to a maternity hospital in Paraná, Brazil, with mastitis. The day after the admission, under treatment with Oxacillin, she evolved to natural birth. During the immediate puerperium, abscedation was observed, and surgical drainage was indicated. The patient refused to be submitted to the procedure and evaded the hospital. One week later, she returned with an engorged, edematous and hyperemic right breast, with fluctuation point at 2h and spontaneous drainage of purulent secretion, in addition to a subareolar hematoma. The patient was submitted to drainage, surgical debridement, removal of the myiasis larvae noticed in the mammary tissue, and placement of a drain. Material sent for culture demonstrated growth of Staphylococcus epidermidis; deescalating broad-spectrum antibiotic regimen started empirically when she was admitted, associated with Ivermectin and Cabergoline. She presented a satisfactory response of the inflammatory process, though dehiscence of the surgical wound occurred, and she was submitted to reconstruction with breast flap during reoperation. The diagnosis of mastitis is based on breast tenderness, local flogistic signs, decreased lactopoiesis, associated with fever and fatigue, and among its serious complications is the breast abscess. The patient presented a unilateral mastitis complaining of pain, edema, local heat and hyperemia, in addition to periareolar purulent discharge and abscedation, suggesting complicated puerperal mastitis. However, because the case was not immediately resolved, the clinical situation deteriorated, with perimammary necrosis and myiasis. The necrosed tissue facilitated the penetration of larvae, a determining factor for this co-infection. It is prevalent in developing countries with poor sanitary conditions, and open wounds or necrosis are more favorable for the growth of larvae. It is necessary to emphasize the importance of good personal hygiene and adequate clothes’ washing, especially in endemic areas of myiasis, to avoid this complication and its late diagnosis.
