Inflammatory pseudotumor simulating malignancy: a rare complication after total hip arthroplasty
Authors: Repše-Fokter Alenka , Fokter Samo Karl 
Published: September 2022

Purpose: Particulate debris created by accelerated polyethylene wear in totally replaced hips causes adverse local reactions. We report an extreme form of such a reaction in a patient who developed progressive thigh pain, weakness and numbness after total arthroplasty of his left hip.
Methods: An abdominopelvic computed tomogram showed a large intrapelvic cystic mass interpreted as a malignant tumor. Dark grayish-green fluid was aspirated from the cyst and cytopathologic examination showed necrotic debris without malignant cells. Biopsy revealed necrosis and abundant foreign body granulation tissue with polarizable debris.
Results: During surgical removal of the cyst a defect of the inner acetabular wall was noted. After successful revision arthroplasty with allograft bone the clinical symptoms improved.
Conclusion: A foreign-body reaction to wear debris may produce an intrapelvic mass and corresponding symptoms. Cytologic and histologic examination of the mass or fluid may aid in interpreting the clinical picture and imaging studies.

Published: September 2022

Purpose: To evaluate the diagnostic accuracy of the UroVysion FISH test for detecting transitional cell bladder cancer on a mixed sample of urological patients.
Methods: Urine samples were collected from patients before cystoscopy. In the case of tumor identification, transurethral resection and histological verification were performed. The fluorescent in situ hybridisation (FISH), using a commercial kit (UroVysion) containing hybridization probes for chromosomes 3, 7, 17, and 9p21, was used. At least 25 morphologically abnormal cells or all cells present on the slides were analyzed.
Results: Of 179 samples, 1 was infected and in 35 (20%), no cells were identified. Test sensitivity was 76.2% (95% CI 52.8–91.8) and specificity 93.6% (95% CI 88.6–96.9); as compared to the data in the literature, this result was considered significant. Most tumors had numerical chromosome aberrations. The prevalence of histologically, which verified tumors, was 11.8%.
Conclusion: Price and time–consuming procedures are major obstacles for use of the UroVysion FISH test. However, neither cytology nor UroVysion FISH are 100% specific. Higher sensitivity compared to cytology, which is evident not only in case of superficial, but also of invasive tumors (like T1) and its ability to provide numerical results, are advantages which may make UroVysion FISH test useful. Thus, this test has potential for future use. cells were identified. Test sensitivity was 76.2% (95% CI 52.8–91.8) and specificity
Pionierinnen im Dickicht der psychoanalytischen Weiblichkeitstheorien
Authors: Grosz-Ganzoni Ita 
Published: September 2022

Die Position der Frauen in der Psychoanalyse ist vielfältig: Es gab die berühmten Patientinnen. Es gab die Pionierinnen, die in gesellschaftlich schwierigen Zeiten ihren Weg zur Psychoanalyse finden mussten, was oft mit dem Verzicht auf ein eigenes Familienleben verbunden war. Und Psychoanalytikerinnen spielten in der kritischen Auseinandersetzung um die Weiblichkeitstheorien Freuds in den 1920er und 1930er Jahren eine zentrale Rolle. Durch das Naziregime und seine Folgen wurde auch diese legendäre Debatte brutal unterbrochen. 40 Jahre danach, mit dem Erstarken der Frauenbewegung in den 1970er Jahren, wurde der Diskurs um die Weiblichkeitstheorien in der Psychoanalyse wieder aufgenommen und weiterentwickelt. 1971 bekamen auch die Schweizer Frauen das Stimm- und Wahlrecht, und ich begann am PSZ die psychoanalytische Ausbildung und ging auch an die berühmten Veranstaltungen der sogenannten «Plattform», einer Gruppe linker, institutionskritischer, vor allem junger KollegInnen, von denen sich die meisten in psychoanalytischer Ausbildung befanden oder sich für die Psychoanalyse interessierten.
Freuds Konzepte der Triebentwicklung, zu der auch die Theorie des Penisneides und des Kastrationskomplexes der Frau gehörte, wurde damals nicht kritisch hinterfragt. Sie gehörten sozusagen zum undiskutierten gewachsenen Felsen der psychoanalytischen Theorie. Die bekannte argentinische Psychoanalytikerin Marie Langer war die erste Person, die am Seminar offen und deutlich diese Theorien in Frage stellte. Für mich bedeutete das eine Aufforderung (eine Erlaubnis?) zum Anders- und Weiterdenken. 1979/80 entstand eine erste Frauengruppe mit Goldy Parin. 1991 wurde der Arbeitskreis für feministische Psychoanalyse gegründet. Mit Psychoanalytikerinnen und psychoanalytisch orientierten Wissenschaftlerinnen aus Deutschland, Österreich und der Schweiz, die sich einmal im Jahr treffen, wird seitdem die Thematik erweitert und vertieft. Das kritische Bewusstsein um Weiblichkeits- und Genderthemen verankerte sich schliesslich auch im PSZ.

This study examined the effect of recurring expenditure financed by external grants on sustainable economic development of sub - Saharan Africa Countries. This paper asked the participation of external grants on the recurring expenditure as one of the source of funds, separately from international finance perspective; the mechanism of domestic did not talk about. This paper filled this gap in literature by determining the recurring expenditure financed by external grants. The study adopted a time series research design where by secondary data were used. The population of the study was external grants and Gross Domestic Product (GDP) from 1988/89 - 2019/20 financial years (Annual Data). The sample size of the research was 32 observations. Purposive sampling was used to choose the Tanzania as a study area of the research; data were collected from the Organization for Economic Co-operation and Development (OECD).The parameters tests such as test for co integration and unit root test was used to investigate co-integrating vectors. After that, Autoregressive Distributive Lag Model (ARDL) was carrying out to find the results. The finding shows that, recurring expenditure financed by external grants influence sustainable economic development; with P- Value of 0.002. At the same time as inflation rate looks to be insignificant with P- Value of 0.719. The study recommends in order encouraging sustainable economic development, government must proceed to promote the relationship with nations by giving development programs which are consistent with supporting programs. additionally, the research predict the requirement for introducing strong policies that will assist and promote strong collaboration with donor nations and spend more in substantial speculation and utilization expenditure in order to increase the level of production as which will affect the sustainable economic development.
Can Atomic Theories Be Evaluated in Terms of Paradigm Shift?
Authors: BAŞARAN Vural , GÖZÜTOK Tarık Tuna 
Published: September 2022

Atom is one of the most controversial and interesting subjects of first natural philosophy and natural sciences. It has preoccupied people's minds since ancient times. This historical adventure, which started with the ancient Greek atomism and Muslim scholars in the Middle Ages also contributed to ideas of atom. Since atomism was far from the possibilities of experimentation in the early periods, it was tried to be proved by rational reasoning. XIX. In the 19th century, the concept of the atom has become one of the fundamental phenomena of modern science. By the 20th century, it was understood that this fundamental particle, which was thought to be indivisible, could be divided into more fundamental parts, thanks to both experimental evidence and scientific and technological developments. In fact, thanks to the atom, energies that could not even be imagined before having begun to be obtained.
In our study, first, this journey of the atom will be discussed. Later, the Kuhnian approach, which deeply affected the history of science studies in the second half of the 20th century, will be examined. For this, the concepts of paradigm and non-comparability will be discussed. Then, the place of this Kuhnian approach in the history of the atom, which is given in the first part of the study, will be discussed. The Kuhnian paradigm was frequently used by Kuhn and his followers, especially in explanations in the history of astronomy. In our study, it will be shown in the explanatory power of this approach is weak when the atomic history is examined.
Prediction and Identification of Gas Hydrates Formation and Reformation in Vertical and Inclined Gas Wells
Authors: Landjobo Pagou Arnold , Guo Xiao , Peng Long , AkhayieMamat Abdoulaye 
Published: September 2022

Abstract
Natural gas hydrate is one of the most promising prospective energy sources which may help alleviate future oil and gas shortages. Natural gas hydrate reformation in gas wells or transportation equipment is a significant concern. It reduces the gas production rate. An exceptionally high reformation rate can drastically reduce productivity and completely plug the equipment. This may result in equipment damage and cause the operating company to abandon the well, resulting in considerable financial losses. In some instances, this may result in staff loss. Consequently, early detection and prediction of natural gas hydrate reformation are essential for the operating companies to avoid lives and financial losses.
This research assumes that hydrate reformation happens gradually in the tubing due to the nucleation of the hydrate slurry adhering to the tubing wall, the natural gas, and the hydrate particle. In this study, we develop the reformed hydrate thickness and the critical gas velocity correlations under the annular flow assumption and several others by establishing the Navier Stokes equation of the Newtonian fluid (gas phase) and non-Newtonian fluid (natural gas hydrate slurry). Consequently, the model developed accounts for the effects of the well's inclination angle, circumferential angle, and tubing diameter. It also incorporates the gas flow rate, pressure, temperature, well characteristics and fluid rheology.
A published gas field data set is utilized to validate the developed model under 10%, 30%, 50%, 70%, and 100% natural gas hydrate void fractions in the tubing. As a result, as the reformed gas hydrate volume increases in the well section, the gas flow rate and the formation pressure increase. Our findings also indicate that the inclination angle, tubing diameter, circumferential angle, temperature, and pressure are statistically the most influential natural gas hydrate reformation factors. Furthermore, the analysis of variance (ANOVA) highlights some significant interactions contributing to the natural gas hydrate reformation, such as tube diameter-inclination angle, temperature-pressure, tube diameter-temperature-pressure, inclination angle-temperature-pressure.

Published: September 2022

Abstract
Numerous well operations, including water injection, varying stimulation approaches, and enhanced oil recovery (EOR) techniques are implemented during the production period in order to maintain the longevity of hydrocarbon production. However, reservoir formation, production, and injection facilities are often impacted by these treatments. Well operations induce inorganic scale to form near-wellbore regions and in various production and injection structures. Consequently, the deposition of scales hinders assessing an optimum hydrocarbon production as their precipitation on formation, various surface, and downhole equipment leads to many problems, including pressure decrement, formation damage, and operational failure of subsurface equipment.
As a control measure to prevent scale precipitation downhole squeeze treatment is commonly used in the petroleum industry. By applying a squeeze treatment, a scale inhibitor solution is introduced into a formation above the formation pressure, allowing the scale inhibitor to get into the deep into near-wellbore formation. Downhole squeezing allows scale inhibitors to adsorb on the internal rock surface to avoid the settling down of scale precipitates. Thus, the study of adsorption of different types of inhibitors, such as chelating agents, polymeric inhibitors, and polyphosphates on formation is becoming necessary. The study incorporated several experimental techniques, including dynamic adsorption experiments using coreflooding setup, ICP-OES (Inductively Coupled Plasma - Optical Emission Spectrometry), and ζ-potential measurements targeting evaluation of adsorption of aminopolycarboxylic acids in carbonate rocks and iron precipitation in calcite mineral. Potential precipitation of iron in varying pH environments and causing the formation of iron-containing scales was assessed through ζ-potential measurements.
The findings reveal that the concentration of aminopolycarboxylic acids plays a significant role in their adsorption on carbonate rocks. The adsorption is also affected by different factors, such as the presence of salts. The results of ζ-potential measurements showed that iron (II) and iron (III) precipitation is controlled by the pH environment in calcite minerals. The treatments with 20 wt% ethylenediaminetetraacetic acid (EDTA) and diethylenetriamine pentaacetate acid (DTPA) produced the highest adsorption capacity in carbonate rock samples by inhibiting 84% and 85% of iron (III) ions, respectively. The encountered permeability damage in the adsorption tests was between 25% and 32%. Moreover, the presence of the salts considerably decreased the adsorption of EDTA and caused almost 20% more permeability reduction.
Unlike the conventional testing methods for inhibitor adsorption, a novel experimental setup, coreflooding was used during the inhibitor adsorption, and scale inhibition in carbonate formation.
Exploring the Nature of the Fine-Structure Constant in the Setting of General Relativity, Quantum Physics, and the Evolution of the Universe
Authors: Williams Lamont 
Published: September 2022

Abstract
This study explores the possibility that the value of the fine-structure constant, α, is linked to the spacetime geometry of the electromagnetic field between two elementary charges, connecting the smooth manifold responsible for gravity with the discreteness of the electromagnetic field. In a step-by-step manner, the study presents a logical basis for the establishment of a fundamental equation for α. It is shown that the equation is directly linked to experimental data involving elementary electric charge, e, and resolves the problems of the Landau pole (when the value of e is infinite at a finite energy level) and triviality (when the value of e is zero at an infinite energy level) in quantum electrodynamics. The equation is also consistent with the evolution of the universe—here, a near-perfect match exists between specific points along the line representing the running of the constant’s value by way of the equation and important periods in the universe’s development. The presented concepts have the potential to assist in efforts to determine how the value of α might be directly derived within the Standard Model.

Abstract
Multi-view learning improves the performance of existing learning tasks by using complementary information between multiple feature sets. In the latest research, multi-view learning model using privilege information is proposed, specific models such as PSVM-2V and MCPK. In these models, views complement each other by acting as privileged information policies, However, a single view contains privilege information that can guide the classifier, and the existing framework does not consider it. In order to use this information to correct multi-view support vector machine classifier, we propose a framework for generating a series of small-scale views based on information hidden in a single view, which extends the original multi-view parallel structure to a hierarchical structure with sub-view mechanism. In this paper, two sub-view learning structures SL-PSVM-2V and SL-MCPK are constructed. The two new models fully exploit the data features in the view. Similarly, they follow the principles of consistency and complementarity. We use the standard quadratic programming solver to solve the new model. In 55 groups of classification experiments and noise sensitivity tests, the new model has better performance than the benchmark model. Statistical comparison shows that the new method is significantly different from the existing methods.

Abstract
Background Nonhuman primates are essentially used for research purposes such as studying diseases, different biological processes and in drug discovery and development programs. Various clinical pathology parameters are used as biomarkers of disease conditions in biomedical research. Detailed reports of these parameters are not available for Indian-origin rhesus macaques. In order to meet the increasing need of information, we conducted this study on 121 adult Indian rhesus macaques (57 wild-sourced and 64 inhouse animals, aged 3-7 years). A total of 18 hematology and 18 biochemistry parameters were evaluated and reported in this study. Data from these parameters were statistically evaluated for significance amongst inhouse and wild-born animals and for difference amongst sexes. Reference range was calculated according to C28-A3 guidelines for reporting reference intervals of clinical laboratory parameters.
Results: Source of the animals and sex appeared to have statistically significant effects on reference values and range. Wild-born animals reported higher WBC, platelets, neutrophils, RBC, hemoglobin, HCT, MCV and total protein values in comparison to inhouse monkeys. Sex-based differences were observed for parameters such as RBCs, hemoglobin, HCT, creatinine, calcium, phosphorus, albumin and total protein amongst others.
Conclusions: Through this study, we have established a comprehensive data set of reference values and intervals for certain hematological and biochemical parameters which will help researchers in planning, conducting and interpreting various aspects of biomedical research employing Indian-origin rhesus monkeys.

AbstractPurpose Children’s sedentary time has increased in recent years, especially during school, while daily physical activity has decreased. The lack of physical activity can contribute to a deterioration in motor performance, which is key to a healthy development. We implemented a comprehensive exercise program in the school setting. Our study aimed to evaluate this program by assessing changes in motor skills after one year and to compare these changes to children who did not participate. Methods A total of 357 children from 5 schools were included in this observational longitudinal cohort study. Motor skills were assessed using the German Motor Test 6–18. Children were either assigned to the exercise group (EG) or waiting group (WG). The EG participated in the physical activity program for one year. Of those, a total of 303 children (EG n = 183; WG n = 120) completed motor tests at baseline and follow-up one year later, and comprise the study population. Linear mixed modeling was used to calculate corrected means and analyze for inter-group differences of change in motor skills after one year between the groups, and to determine the effect of sex, age group and weight category on the change in motor skills. Results After one year of additional physical activity, the EG improved significantly more strongly in 6 out of 8 motor skill tests than the WG. After the adjustment for sex, age, and BMI the improvement is still significantly stronger in the EG in 4 of 8 motor skill tests (sprint, side jumps, both p = 0.017; stand and reach, p = 0.012; ergometry, p = < 0.001), when compared to the WG. Girls improved more strongly in the sit-ups than boys, 2nd graders more than 5th graders in the backwards balance and the ergometry, non-overweight pupils more in the standing long jump than overweight children. Conclusions Participating in the exercise program for one year positively influenced motor skill development in schoolchildren. Our data suggest that girls were not disadvantaged, and even improved more than boys in the sit-ups, and that overweight pupils profited as much as their non-overweight peers in all categories but one. The exercise program, simple and easily implemented into the school routine, is effective in increasing motor skills and physical fitness.
