Successful Pregnancy in a Patient with Long-Standing Acromegaly – a Case Report
Authors: Gliga Maximilian Cosma , Pașcanu Maria Ionela , Gliga Camelia , Réti Zsuzsanna 
Published: November 2020

Abstract

Introduction: Acromegaly is a rare endocrine disorder of the growth hormone (GH)-insulin-like growth factor 1 (IGF1) metabolism that can affect women of fertile age. Although uncommon, pregnancies in acromegalic women can occur, with data regarding the management of these cases being very limited, mostly consisting of case reports.

Case Presentation: We present the case of an acromegalic woman, first diagnosed at the age of 22, after the surgical resection of a pituitary mass. Throughout the evolution, she received conventional radiotherapy and has been treated with somatostatin receptor ligands (SRLs), dopamine agonists (DAs), and GH-blockers. At the age of 37, the patient decided to become pregnant while she was on Pegvisomant and DA therapy. The treatment was stopped, and the patient became pregnant at the age of 38. Tumor size and IGF-1 values have remained stable throughout the pregnancy, and no complications occurred. A healthy child with normal birth weight was delivered on term through Cesarean section.

Conclusions: Managing pregnant women with acromegaly is challenging because of the little available data regarding the safety of medical treatment and a high interindividual variability of GH-IGF-1 evolution during this period. The particularity of our case was a patient with a long history of acromegaly, who had an uneventful pregnancy despite stopping all medical treatment.

Abstract
This research aims to assess the impacts of soil use management on runoff, soil losses, and their main soil controls in vegetable cropland (CROP), tilled olives (OT), and grass-covered olive orchards (OGC) on Leptosol in Croatia. Soil analysis and rainfall simulation experiments were conducted to quantify runoff (Run), soil, and nutrient losses. Bulk density (BD) was significantly higher at OT plots, in addition to the CROP plots. Water-stable aggregates (WSA), mean weight diameter (MWD), and soil organic matter (OM) were significantly higher in OGC plots compared to the other land uses. Run and soil loss (SL) were significantly higher in CROP and OT plots compared to the OGC plots. The CROP plots showed soil management that can be considered as unsustainable with 52, 68- and 146-times higher losses of phosphorus (P loss), nitrogen (N loss), and carbon (C loss) compared to the OGC plots. The principal component analysis showed that MWD was associated with vegetation cover (VC), water-holding capacity (WHC), WSA, OM, total nitrogen (TN), time to ponding (TP), and time to runoff (TR). These variables were negatively related to P2O5, Run, SL, and P, N, and C loss. Results indicate the need for the adoption of conservation strategies in croplands and olive orchards.

Published: November 2020

Abstract

Aim. Assessment of adherence to dietary recommendations by children and adolescents during steroid therapy in the treatment of acute lymphoblastic leukemia (ALL).

Material and methods. The study was conducted among parents of children with ALL, aged from 1 to 17 years, treated at the Department of Paediatrics, Hematology and Oncology of the University Clinical Centre in Gdańsk. The paper uses the method of a diagnostic survey, the questionnaire technique. The research tool was an anonymous self-constructed questionnaire.

Results. The study included 16 parents (44.4%) of female children and 20 parents (55.6%) of male children. Normal body weight was found in most of the children (22/36 children). Grade 1 hypertension was found in 15/36 children and grade 2 hypertension in 6/36. In 31/36 children, the blood glucose level was 70-180 mg%. The number of 22/36 examined children used a diet with a low glycemic index. As many as 29/36 parents of children and adolescents with ALL followed the diet recommended by a doctor.

Conclusions. 1) Most children with ALL have normal body weight during steroid therapy. 2) Children with ALL are subject to arterial hypertension during steroid therapy. 3) Most parents or legal guardians of children and adolescents with ALL adhered to dietary recommendations during steroid therapy.
Numerical Simulation of the Ducted Propeller and Application to a Semi-Submerged Vehicle
Authors: Zou Jin , Tan Guoge , Sun Hanbing , Xu Jie , Hou Yongkang 
Published: November 2020

Abstract
The self-propulsion test of underwater vehicles is the key technique for predicting and evaluating the navigation performance of these submersibles. In this study, the numerical simulation of a standard propeller JD7704+Ka4-70 is first presented and the results are compared with experiments to validate the numerical approaches. The reason why the propulsion efficiency of the ducted propeller is higher than that of the conventional propeller is explored. Then, the paper proposes a series of numerical simulations conducted to test the performance of the ducted propeller designed according to the JD7704+Ka4-70 in order to match with the unmanned semi-submerged vehicle (USSV), and the propeller’s open water characteristic curves are obtained. The results show a reasonable agreement with the regression analysis. Afterwards, the numerical simulations focus on a self-propulsion test of the USSV with the designed ducted propeller and the self-propulsion point is obtained. The streamlines through the hull as well as the ducted propellers are clearly obtained, together with the velocity distributions of the propeller plane. The results vividly demonstrate the hydrodynamic performance of the USSV with the designed propellers. In this paper, all the CFD simulations are based on the numerical software, Star-CCM+, and use the Reynolds-averaged Navier‒Stokes (RANS) equations with the shear stress transport (SST) k-omega turbulence model.
Simulation and Experimental Study of Hydraulic Cylinder in Oscillating Float-Type Wave Energy Converter
Authors: Lai Wenbin , Li Detang , Xie Yonghe 
Published: November 2020

Abstract
Hydraulic cylinders play a vital role in the energy output (PTO) system of an oscillating float-type wave energy converter, whose function is to convert the mechanical energy captured by the float from the waves into hydraulic energy. The performance of the hydraulic cylinder determines the conversion efficiency of mechanical energy to hydraulic energy in the system; therefore, it is necessary to study the working mechanism of the hydraulic cylinder. This paper takes a self-developed oscillating float-type wave energy converter as the research object, and studies the working mechanism of its hydraulic cylinder, and uses the linear analysis method to derive the critical self-excited vibration curve of the hydraulic cylinder. In addition, the effects of the external load, hydraulic cylinder load mass, stroke length, spring stiffness and piston area on the performance of the hydraulic cylinder were studied by AMESim simulation software. According to the simulation results, a physical model of the hydraulic cylinder is established. Finally, the physical model is tested in a hydrodynamic pool. The test results show that the hydraulic cylinder can stably and efficiently convert mechanical energy into hydraulic energy even under small waves, thus verifying the rationality of the hydraulic cylinder design.
Design and Mechanical Analysis of a Composite T-Type Connection Structure for Marine Structures
Authors: Li Xiaowen , Zhu Zhaoyi , Li Yan , Hu Zhe 
Published: November 2020

Abstract
A new T-type connection structure consisting of composite sandwich plates, reinforced cores and adhesive was proposed for the construction of lightweight ships to resolve connection problems between bulkheads and decks of composite lightweight ship superstructures. Based on the design principles and mechanical properties of composite structures, the mechanical behaviour of the structure under a dangerous loading condition was investigated. In addition, the ultimate bearing capacities and damage modes were examined, the results of which demonstrated that the strength of the structure is weak, and that the adhesive and reinforced core between the face plate and the web plate is the primary weakness of the structure. A numerical simulation method was verified using the results of the mechanical tests, and five characteristic paths at the connection area were established. The stresses and displacements along the five paths were calculated using the numerical method. Then, variations in the geometric parameter and the strength and weight of the connection were summarised. The optimal angle of the adhesive bonding area is approximately 60°, which supports the optimal design and practical application of the lightweight ship adhesive-bonded connection structure.
Pilot Symbol Error Re - Orthogonalization in 2 × 2 MIMO Systems of Wireless Communication
Authors: Romanuke Vadim 
Published: November 2020

Abstract
A 2×2 MIMO wireless communication system with channel estimation is simulated, in which two transmit, and two receive antennas are employed. The orthogonal pilot signal approach is used for the channel estimation, where the Hadamard sequences are used for piloting. Data are modulated by coherent binary phase-shift keying, whereupon an orthogonal space-time block coding subsystem encodes information symbols by using the Alamouti code. Based on the simulation, it is ascertained a possibility to decrease the bit-error rate by substituting the Hadamard sequences for the sequences having irregular structures, and constituting the eight known orthogonal bases. Considering a de-orthogonalization caused by two any pilot sequence symbol errors, the bit-error rate is decreased by almost 2.9 %. If de-orthogonalizations are caused by two repeated indefinite, and definite pilot sequence symbol errors, the decrements are almost 16 % and 10 %, respectively. Whichever sequences are used for piloting, the 2×2 MIMO system is ascertained to be resistant to the de-orthogonalization if the frame is of 128 to 256 symbols piloted with 32 to 64 symbols, respectively.
Analogicity in Computer Science. Methodological Analysis
Authors: Stacewicz Paweł 
Published: November 2020

Abstract
Analogicity in computer science is understood in two, not mutually exclusive ways: 1) with regard to the continuity feature (of data or computations), 2) with regard to the analogousness feature (i.e. similarity between certain natural processes and computations). Continuous computations are the subject of three methodological questions considered in the paper: 1a) to what extent do their theoretical models go beyond the model of the universal Turing machine (defining digital computations), 1b) is their computational power greater than that of the universal Turing machine, 1c) under what conditions are continuous computations realizable in practice? The analogue-analogical computations lead to two other issues: 2a) in what sense and to what extent their accuracy depends on the adequacy of certain theories of empirical sciences, 2b) are there analogue-analogical computations in nature that are also continuous? The above issues are an important element of the philosophical discussion on the limitations of contemporary computer science.
The Intuitive Concept of Information: An Analysis
Authors: Król Zbigniew 
Published: November 2020

Abstract
This paper seeks to determine the intuitive meaning of the concept of information by indicating its essential (definitional) features and relations with other concepts, such as that of knowledge. The term “information” – as with many other concepts, such as “process”, “force”, “energy” and “matter” – has a certain established meaning in natural languages, which allows it to be used, in science as well as in everyday life, without our possessing any somewhat stricter definition of it. The basic aim here is thus to explicate what it amounts to in the context of its intuitive meaning as encountered in natural languages, what the subject of cognition implicitly presumes when using the term, and to which ontological situations it can be applied. I demonstrate that the essential features of the notion of information include the presence of a material medium, its transformation, the recording and reading of information encoded in the medium, and the grasp of what is recorded, coded and transmitted as an intentional object, where the latter is construed in terms broadly in line with the ontologies of Husserl and Ingarden. Along the way, a number of issues relating to the notion of information are also pointed out: the problem of informational identity, of the existence of virtual objects, and of the choice of an adequate information carrier, as well as formal-ontological problems, including those which concern relations between information carriers and intentional objects.
Fostering the Mediating Role of the Feeling of Belonging to an Organization Among Romanian Members of Generation Z

Published: November 2020

Abstract
The addition of Generation Z/Centennials to the workplace landscape will bring about new challenges for the management of any organization. To tackle the changing work environment and workforce, we conducted a survey-based empirical exploratory study among students in economics from two universities located in the western part of Romania. Our study proposes an alternative view of the motivational potential, including the feeling of belonging to an organization in work settings. The aim was to explore the potential for the feeling of belonging to play the role of mediator between four distinct career attitudes and the turnover intention in the specific case of Romanian Generation Z members. Additionally, we investigated which variables are significant predictors for the feeling of belonging to an organization. The results indicate that is efficient to invest in creating belongingness for those Generation Z members inclined towards making moves between jobs and organizations (OMPA), for those who present the mental capacity to be mobile (BMA) and for those who can be adaptive in terms of performance and learning demands (SDA). For those Romanian Generation Z members who use their internal values to provide guidance and measure for success, including the feeling of belonging to an organization in work settings seems to be inefficient.
Analiza zmian powierzchni nieprzepuszczalnych w badaniu suburbanizacji na przykładzie Poznania
Authors: Łachowski Wojciech 
Published: November 2020

AbstraktTereny nieprzepuszczalne to miejsca powstałe głównie w wyniku działalności człowieka, w które nie może infiltrować woda. Do materiałów nieprzepuszczalnych zalicza się m.in. asfalt czy beton, czyli podstawowy budulec miast. W zależności od udziału terenów nieprzepuszczalnych zdefiniować można klasy gęstości tkanki miejskiej. Przykładowo, wartość wskaźnika w przedziale 10–30% świadczy o niskiej gęstości i jest charakterystyczna dla zabudowy jednorodzinnej rozproszonej. Zastosowanie metody analizy zmian tego wskaźnika może być pomocne w określeniu zasięgu suburbanizacji. Aby ocenić przydatność wspomnianej metody, przenalizowałem zmiany w udziale powierzchni nieprzepuszczalnych dla strefy demograficznej suburbanizacji Poznania w latach 1992–2018. W tym celu wykorzystałem otwarte dane satelitarne Landsat. Pobrane zdjęcia poddałem klasyfikacji pikselowej pozwalającej na stworzenie mapy obszarów przepuszczalnych i nieprzepuszczalnych. W pierwszym kroku wyłączyłem z analizy obszary wodne, roślinność oraz większość gleb, używając metody progowania wskaźników spektralnych NDVI (pokazujących kondycję roślinności), NDWI (pozwalających na detekcję obiektów wodnych) oraz DBSI (pozwalających na odróżnienie gleb od powierzchni nieprzepuszczalnych). Pozostałe obszary poddałem klasyfikacji z wykorzystaniem algorytmu maszyny wektorów nośnych (SVM). Wyniki zostały zagregowane do siatki 25 ha heksagonów. Porównanie rezultatów dla dwóch okresów pozwoliło na wskazanie, w których miejscach poziom zainwestowania rósł najszybciej. W tych obszarach występowała suburbanizacja. Dla Poznania powierzchnie nieprzepuszczalne przyrastały najintensywniej na obszarze znajdującym się za jego zachodnią granicą. Przedstawiona metoda okazała się przydatna w określeniu zasięgu występowania procesów suburbanizacyjnych. Wskaźnik nieprzepuszczalności nie może być jednak stosowany jako samodzielny wskaźnik rozlewania się miast, gdyż pokazuje tylko jeden z wymiarów tego zjawiska.

Risk Factors Predicting the Necessity of Renal Ultrasound in the Emergency Department
Authors: Merhav Goni , Razi Nira 
Published: November 2020

Objectives:
Renal ultrasound (US) is widely used for diagnosing renal pathologies, though few of them, such as obstructive uropathy, require emergent urological intervention. During on-call hours, when medical staff is limited, it is important to prioritize which renal US examinations will be done. The aim of this study was to evaluate patient risk factors to predict the necessity of emergent renal US in the emergency department (ED).

Material and Methods:
All adult patients referred for renal US from the ED, during on-call hours from May 2015 to April 2017, were retrospectively included. The mean age was 64 years (18–98). Data were collected from the patients’ medical records. Urological intervention performed within the first 24 h following the US examination was recorded. Multivariate analysis was performed.

Results:
About 66% of the patients did not have a permanent urethral catheter, history of renal stones, or known abdominal or pelvic mass. None of these patients required an urgent urological intervention. The receiver operating characteristic curve was calculated at 0.883, 95% CI (0.84–0.92).

Conclusion:
Using only three variables, we can greatly reduce the number of renal US examinations done at on-call hours allowing for prioritization of only the necessary examinations.

Background:An anaplastic large cell lymphoma (ALCL) involving the cervical spine and leading to quadriplegia is very rare.Case Description:A 48-year-old immunocompetent male presented with quadriplegia that warranted an anterior cervical corpectomy/fusion. He was previously being presumptively treated for cervical disease attributed to tuberculosis. The histopathology and immunohistochemistry revealed an ALCL that was anaplastic lymphoma kinase (ALK) negative. The patient had a favorable response to surgery followed by CHOEP (cyclophosphamide, doxorubicin, vincristine, etoposide, and prednisolone) chemotherapy.Conclusion:ALK-negative ALCL presenting with quadriplegia due to primary involvement of cervical spine is extremely rare, but must be diagnosed and appropriately managed.
