Predictive Value of Positive Margins in Diagnostic Biopsies of Dysplastic Nevi
Authors: Dickman Jeffrey S. , Haddad Reem M. , Racette Andrew
Published: January 2020

Dysplastic nevi (DN) are common and controversial and the best choice for management of DN after diagnosis is not always clear. The presence of positive margins found on diagnostic biopsy is used by many dermatologists when deciding whether to re-excise these lesions. In order to quantify the predictive value of positive margins in diagnostic biopsies of DN, we performed a review and analysis of the concordance between the histological findings of biopsies and their subsequent excisions. A total of 122 pathology reports from diagnostic biopsies of DN with nevus cells present at the tissue margin were reviewed. Within this sample, 68 total postbiopsy excisions had been performed. The excisional pathology reports were reviewed for the presence of residual or recurrent nevus cells. Residual nevus cells were reported in 29 of 63 available excisional pathology reports illustrating a positive predictive value (PPV) of positive margins in diagnostic biopsies of DN of 46.0%. We present this value along with PPVs from the very few existing similar studies. The quantified predictive value of positive margins in diagnostic biopsies is useful information for providers who must make decisions regarding the best treatment options for patients with DN. The low PPV of positive margins lends further evidence that DN of moderate severity or less may simply be monitored.

Published: January 2020

Azathioprine is a cornerstone of the therapy of Crohn’s disease. Unfortunately, infections and malignancies are relatively common adverse effects related to this drug; however, cirrhosis is exceptionally reported as a side effect. We report the case of a 49-year-old male patient with ileocolonic steno-penetrating Crohn’s disease who developed hepatic cirrhosis while treated with azathioprine. After taking azathioprine for 3 years with regular follow-up, he developed pancytopenia, and liver cirrhosis was diagnosed with ultrasound, abdomen computed tomography scan, transient elastography, and liver biopsy. As all other causes of liver damage were excluded, azathioprine was believed to be the cause of liver injury and therefore was interrupted.

Published: January 2020

Aims. Fibrin formation and histidine-rich glycoprotein (HRG) are involved in primary hemostasis and wound healing. Little is known regarding the relationship of clot characteristics, bleeding time, and wound healing. Methods and Results. We studied 154 patients with coronary artery disease (CAD) and 154 subjects free of CAD matched for age, obesity, and current smoking. We evaluated bleeding time (BT) using standardized skin incisions on a forearm, along with plasma clot permeability (Ks), clot lysis time (CLT), and histidine-rich glycoprotein (HRG). Compared with controls, BT was 45% shorter in CAD cases. CAD patients had 32% lower Ks and 17% longer CLT as well as 50% lower HRG compared with controls (all p<0.001). After adjusting for potential confounders, Ks and HRG levels were independent predictors of prolonged BT in CAD patients (OR 23.70, 95% CI 4.65-120.8 and OR 10.27, 95% CI 2.05-51.31, respectively) and controls (OR 10.89, 95% CI 2.31-51.11 and OR 4.54, 95% CI 1.07-19.27, respectively). Scar formation (n=79, 25.6%) was independently predicted by both short and prolonged BT in CAD cases (OR 21.87, 95% CI 7.41-64.55 and OR 10.17, 95% CI 2.88-35.97) and controls (OR 5.94, 95% CI 2.29-15.41 and OR 14.76, 95% CI 4.29-50.77, respectively). Conclusions. The study shows that plasma fibrin clot density and HRG may influence BT and that appropriate skin wound healing is associated with medium BT. Translational Perspective. Elucidation of the complex relationships between plasma fibrin clot phenotype and wound healing might have important practical implications.
Influence of Degree of Compaction on Unsaturated Hydraulic Properties of a Compacted Completely Decomposed Granite

Published: January 2020

It is crucial to understand hydraulic properties, i.e., soil-water characteristic curve (SWCC) and unsaturated permeability function (UPF), of completely decomposed granite (CDG) for relevant engineering projects in southeastern China. Previous studies mainly focused on SWCCs of CDG, whereas UPFs of CDG have not yet been well understood. In this study, the effects of the degree of compaction (DOC) on SWCCs and UPFs of CDG were investigated based on experiments where suction range was from 0 to 500 kPa. The microstructure of soil specimens was then analyzed by mercury intrusion porosimetry (MIP). Furthermore, the UPFs of CDG under different values of DOC were calculated using four prediction models and compared with experimental data. Results showed that the pore volume of specimens at higher DOC was smaller than that at lower DOC, and there were more macropores observed in specimens at lower DOC. Meanwhile, it was found that increasing compaction effort produced negligible influence on the volume of micropores. When the suction was less than 100 kPa, the permeability was reduced with the increase in DOC, due to the decrease of macropore volume. However, the influence of DOC on SWCCs and UPFs became marginal when the suction exceeded 100 kPa. The Fredlund and Xing model provided the best prediction of UPF among the four models when suction was smaller than air entry value (AEV). It is suggested that these models could be improved to capture UPFs at higher suctions than AEV by considering suction-induced volume contraction.

Authors: Alhendal Yousuf , Gomaa Abdalla , Bedair Gamal , Kalendar Abdulrahim
Published: January 2020

The energy and exergy of low‐global warming potential (GWP) refrigerants were investigated experimentally and theoretically. Refrigerants with a modest GWP100 of  ≤ 150 can be sufficient for bringing down emissions which were concerned for the automotive air‐conditioning system. Three types of low‐GWP refrigerants, R152a, R1234yf, and R1234ze(E), were examined with particular reference to the current high‐GWP of R134a. The effect of different evaporating and condensing temperatures in addition to compressor speed was considered. The purpose was to bring a clear view of the performance characteristics of possible environment friendly alternatives of R134a. The analysis was carried out with compressor power, cooling capacity, coefficient of performance, exergy destruction, and exergy efficiency. It was noted that the total exergy destruction of R1234yf was reduced by 15% compared to that of R134a. The refrigerant R1234ze(E) has the highest energetic and exergetic performance compared with the other investigated refrigerants.

Published: January 2020

Among patients who develop anaphylaxis during anesthesia, anaphylaxis caused by a neuromuscular blocking agent has the highest incidence. In patients who developed IgE-mediated anaphylaxis, and cross-reactivity among NMBAs is a concern in subsequent anesthetic procedures. We present a patient who developed rocuronium-induced anaphylaxis in whom the skin prick test (SPT) and intradermal test (IDT) could identify a safe drug to use in the subsequent anesthetic procedure. A 32-year-old female developed anaphylactic shock at the induction of general anesthesia. She recovered by administration of hydrocortisone and epinephrine. Skin tests including the SPT followed by the IDT revealed rocuronium as the drug that caused anaphylaxis and vecuronium as a safe drug to use for the subsequent general anesthesia. She safely underwent surgery with general anesthesia using vecuronium one month after the skin testing. There are not many reports on the effectiveness of the SPT followed by IDT in identifying the causative drug as well as a safe drug to use in the subsequent anesthetic procedure following anaphylaxis during anesthesia. The usefulness of the SPT should be re-evaluated.
Ischemia/Reperfusion Injury: Pathophysiology, Current Clinical Management, and Potential Preventive Approaches

Published: January 2020

Myocardial ischemia reperfusion syndrome is a complex entity where many inflammatory mediators play different roles, both to enhance myocardial infarction-derived damage and to heal injury. In such a setting, the establishment of an effective therapy to treat this condition has been elusive, perhaps because the experimental treatments have been conceived to block just one of the many pathogenic pathways of the disease, or because they thwart the tissue-repairing phase of the syndrome. Either way, we think that a discussion about the pathophysiology of the disease and the mechanisms of action of some drugs may shed some clarity on the topic.

Published: January 2020

Aluminium is known to accelerate oxidative stress, amyloid beta (Aβ) deposition, and plaque formation in the brain of rats.Objective. The present study is aimed at studying the neuroprotective effects of eugenol following aluminium-induced neurotoxicity on caspase-3, apoptotic proteins (Bcl-2 and Bax), and oxidative stress markers in Wistar rats such as superoxide dismutase (SOD), glutathione peroxidase (GPx), nitric oxide (NO), and assay oxidative stress to mitochondrial DNA (mtDNA) by measuring the levels of 8-hydroxy-2-deoxyguanosine (8-OHdG).Materials and methods. Twenty (20) adult Wistar rats were randomly divided into four (4) groups with five animals in each group. Route of administration was oral throughout the duration of this study and this study lasted for 21 days. Rats were sacrificed 24 hours after administration of the last dose (i.e., day 22) with 0.8 mg/kg ketamine as an anaesthetic agent.Results. Exposure to AlCl3resulted in a significant (p<0.01) elevation in the levels of nitric oxide and 8-hydroxy-2-deoxyguanosine (8-OHdG), enhanced the activity of caspase-3, increased the level of proapoptotic protein Bax and reduced the levels of antiapoptotic protein Bcl-2, and significantly (p<0.01) reduced the levels of SOD and GPx. However, treatment with eugenol resulted in a significant reduction (p<0.01) in the levels of nitric oxide (NO) and 8-hydroxy-2-deoxyguanosine (8-OHdG) levels, inhibited the activity of caspase-3, increased levels of Bcl-2 and significantly (p<0.05) reduced levels of Bax protein, respectively, and also significantly (p<0.05) increased the levels of SOD and GPx. Our results would hereby suggest that eugenol would provide a therapeutic value against aluminium-induced oxidative stress as related to antioxidant and antiapoptotic activities.

Authors: Mosavat Maryam , Omar Siti Zawiah , Jamalpour Sajad , Tan Peng Chiong
Published: January 2020

Background. Defects in incretin have been shown to be related to the pathogenesis of type 2 diabetes. Whether such a deficiency happens in gestational diabetes mellitus (GDM) remains to be confirmed. We assessed the association of fasting glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) with GDM. We also studied the longitudinal circulation of these peptides during pregnancy and afterwards. Methods. 53 women with GDM (30 managed with diet only (GDM-diet) and 23 treated with insulin (GDM-insulin)) and 43 pregnant women with normal glucose tolerance (NGDM) were studied, with GIP and GLP-1 levels measured at 24–28 weeks (E1), prior (E2) and after (E3) delivery, and postpuerperium (E4). Results. Basal GIP was shown to be low in GDM groups compared to NGDM in E1, and in E4 for GDM-diet. GLP-1 was low in GDM groups during pregnancy and afterwards. At E1, serum GIP and GLP-1 were inversely associated with GDM and participants with lower levels of GIP (<0.23 ng/mL) and GLP-1 (<0.38 ng/mL) had a 6 (95% CI 2.5-14.5)- and 7.6 (95% CI 3.0-19.1)-fold higher risk of developing GDM compared with the higher level, respectively. In the postpuerperium, when there is a drop in β-cell function, participants with previous GDM (pGDM) presented lower GLP-1 (in both GDM subgroups) and lower GIP in GDM-diet subgroup compared to controls. Conclusion. There is an independent, inverse association between fasting incretins and higher risk of GDM. Furthermore, lowered levels of these peptides may play an important role in the abnormality of glucose regulation following pregnancy.

Authors: Hewayde Esam , Pachenari Alireza , Al-Eleaj Hussin
Published: January 2020

Recycled aggregates were widely used in the concrete industry as a replacement of natural aggregates in the last two decades. In this study, the resistance of concrete mixtures having various levels of recycled aggregate as a replacement of natural coarse aggregate to the attack of magnesium and sodium sulfates was investigated. Five mixtures made with 0%, 25%, 50%, 75%, and 100% recycled aggregate were partially immersed in magnesium and sodium sulfate solutions having concentrations of 2.5%, 4.5%, and 6.5% and subjected to drying-wetting cycles for a total of 10 weeks. Mass losses of concrete specimens owing to the attack of sulfate solutions and the effect of drying-wetting cycles were recorded weekly. Results show that the incorporation of recycled aggregate decreased the compressive strength of concrete at ages of 7 and 28 days. The decline in the compressive strength was more significant when the replacement percentage exceeds 50%. Mass losses of concrete specimens were found to be increased as the level of recycled aggregate increased. Mass losses of concrete specimens having 100% recycled aggregate were approximately as twice as those of concrete specimens having 0% recycled aggregate owing to 10 weeks of partial immersion in magnesium sulfate solutions of concentrations of 2.5%, 4.5%, and 6.5%. The attack of sodium sulfates was less aggressive than that of the magnesium sulfates. Results also show that the reduction in the compressive strength is directly proportional to the mass loss following a linear equation of R-squared value of 0.937.

Published: January 2020

Purpose:

The purpose of this study was to evaluate antigen experienced T cells in peripheral blood lymphocytes (PBL) for responses to p53 neoantigens.

Experimental Design:

PBLs from patients with a mutated TP53 tumor were sorted for antigen-experienced T cells and in vitro stimulation (IVS) was performed with p53 neoantigens. The IVS cultures were stimulated with antigen-presenting cells expressing p53 neoantigens, enriched for 41BB/OX40 and grown with rapid expansion protocol.

Results:

T-cell responses were not observed in the PBLs of 4 patients who did not have tumor-infiltrating lymphocyte (TIL) responses to mutated TP53. In contrast, 5 patients with TIL responses to mutated TP53 also had similar T-cell responses in their PBLs, indicating that the PBLs and TILs were congruent in p53 neoantigen reactivity. CD4+ and CD8+ T cells were specific for p53R175H, p53Y220C, or p53R248W neoantigens, including a 78% reactive T-cell culture against p53R175H and HLA-A*02:01. Tracking TCRB clonotypes (clonality, top ranked, and TP53 mutation-specific) supported the enrichment of p53 neoantigen–reactive T cells from PBLs. The same T-cell receptor (TCR) from the TIL was found in the IVS cultures in three cases and multiple unique TCRs were found in another patient. TP53 mutation–specific T cells also recognized tumor cell lines bearing the appropriate human leukocyte antigen restriction element and TP53 mutation, indicating these T cells could recognize processed and presented p53 neoantigens.

Conclusions:

PBL was a noninvasive source of T cells targeting TP53 mutations for cell therapy and can provide a window into intratumoral p53 neoantigen immune responses.

Authors: Molodetska Kateryna , Tymonin Yuriy , Melnychuk Ihor
Published: January 2020

Social networking services are one of the most popular mass media and are used as an effective tool for information confrontation due to their functional characteristics. Existing models of information confrontation take into account the redistribution between conflict parties of only one kind of resource, although in the social networking services there is a need to consider additional factors that determine the effectiveness of virtual communities’ opposition. A conceptual model of information confrontation of virtual communities in social networking services has been developed, and it includes three-layer dynamics of the number of actors, growth of information resources of virtual communities and dynamics of spending resources for the confrontation conduct. The model also takes into account the peculiarities of the antagonistic conflict of virtual communities’ actors through the choice of a differential equation that corresponds to the type of its dynamics. The offered conceptual model formalizes the behavior of virtual communities’ actors in the conditions of antagonistic conflict. At the same time, it allows to investigate the peculiarities of using different strategies to carry out the information fight of virtual communities in social networking services, to choose optimal strategies, to predict the development of conflicts in the information space and to develop effective measures to counter threats to the state’s information security.

Published: January 2020

The rate of increase in energy consumption and high costs in addition to the depletion of existing resources has a significant impact on our standard of living for next generations. In this case, the priority is to develop alternative cost-effective sources for powering the residential and non-residential buildings. This paper proposes and develops a design of a modified small two-story residential solar house for a medium-sized family located in Cairo, Egypt. This modified solar house meets almost all its energy demands including space heating by using solar air collector with a pebble storage unit in winter and a summer cooling system using wind catcher theory. Hot water is obtained throughout the day by using a steel sheltered water storage tank with a capacity of 1000 liter. Finally, the proposed heating system of the solar house is sized and modeled.
Direct torque control of IM using PID controller
Authors: Abdullah Ali Najim , Ali Mohammed Hasan
Published: January 2020

Direct torque control "DTC" technique is one of a high performance control system of an AC motor drive, which was proposed after the vector oriented control scheme during the resent 25 years. It has been developed rapidly for its concise system scheme, transient and dynamic performance. The DTC mechanism consists of voltage vector selection table, two hysteresis comparators and two estimators one for stator flux and another for electromagnetic torque. DTC is directly control torque and flux by using Voltage Source Inverter VSI, space vector and stator flux orientation and indirect speed regulated. A several control techniques can be used for improving the torque and flux performance.

In this paper, the DTC with Proportional-Integral-Derivative (PID) controller used to improve the starting and dynamic performance of asynchronous motor AM, which gives good torque and flux response, best speed control and also minimize the unacceptable torque ripple. The mathematical model of DTC with PID controller of 3-phase induction motor IM are simulated under Matlab-Simulink. Therefore, the DTC based on PID controller has good performance of IM compared to classical DTC for starting, running state and also during change in load.

Authors: Rajanna B. V. , Kiran Kumar Malligunta
Published: January 2020

The fast and accurate modeling topologies are very much essential for power train electrification. The importance of thermal effect is very important in any electrochemical systems and must be considered in battery models because temperature factor has highest importance in transport phenomena and chemical kinetics. The dynamic performance of the lithium ion battery is discussed here and a suitable electrical equivalent circuit is developed to study its response for sudden changes in the output. An effective lithium cell simulation model with thermal dependence is presented in this paper. One series resistor, one voltage source and a single RC block form the proposed equivalent circuit model. The 1 RC and 2 RC Lithium ion battery models are commonly used in the literature are studied and compared. The simulation of Lithium-ion battery 1RC and 2 RC Models are performed by using Matlab/Simulink Software. The simulation results in his paper shows that Lithium-ion battery 1 RC model has more maximum output error of 0.42% than 2 RC Lithium-ion battery model in constant current condition and the maximum output error of 1 RC Lithium-ion battery model is 0.18% more than 2 RC Lithium-ion battery model in UDDS Cycle condition. The simulation results also show that in both simple and complex discharging modes, the error in output is much improved in 2 RC lithium ion battery model when compared to 1 RC Lithium-ion battery model. Thus the paper shows for general applications like in portable electronic design like laptops, Lithium-ion battery 1 RC model is the preferred choice and for automotive and space design applications, Lithium-ion 2 RC model is the preferred choice. In this paper, these simulation results for 1 RC and 2 RC Lithium-ion battery models will be very much useful in the application of practical Lithium-ion battery management systems for electric vehicle applications.

A new partial image encryption method for document images using variance based quad tree decomposition
Authors: Revanna C. R. , Keshavamurthy C.
Published: January 2020

The proposed method partially and completely encrypts the gray scale Document images. The complete image encryption is also performed to compare the performance with the existing encryption methods. The partial encryption is carried out by segmenting the image using the Quad-tree decomposition method based on the variance of the image block. The image blocks with uniform pixel levels are considered insignificant blocks and others the significant blocks. The pixels in the significant blocks are permuted by using 1D Skew tent chaotic map. The partially encrypted image blocks are further permuted using 2D Henon map to increase the security level and fed as input to complete encryption. The complete encryption is carried out by diffusing the partially encrypted image. Two levels of diffusion are performed. The first level simply modifies the pixels in the partially encrypted image with the Bernoulli’s chaotic map. The second level establishes the interdependency between rows and columns of the first level diffused image. The experiment is conducted for both partial and complete image encryption on the Document images. The proposed scheme yields better results for both partial and complete encryption on Speed, statistical and dynamical attacks. The results ensure better security when compared to existing encryption schemes.

Authors: Rincón Alejandro , Florez Gloria Yaneth , Hoyos Velasco Fredy E.
Published: January 2020

This work shows simulation results for subsurface vertical flow constructed wetland (VFCW) using a series CSTR model. The VFCW considered received the outflow from a domestic wastewater treatment plant. In addition, it was planted with Cyperus sp. and filter media was unsaturated. The model was based on an unsteady state mass balance for ammonia, nitrites, and nitrates, using one to three series CSTRs. Nitrogen transformation mechanisms considered were ammonification, nitrification, plant uptake and denitrification. The following effects were evaluated: the number of reacting CSTRs from one to three; the occurrence of the reaction in second and third CSTRs for the case that three CSTRs hold; the use of either equal or different values of reaction rate parameters between CSTRs; and the discretization of the reaction rate parameters. The inflow and outflow measurements of ammonium, nitrites, and nitrates were used for model calibration. The estimated parameters included the reaction rate coefficients and reactor water volume. The coefficient of determination (R2) evidenced a satisfactory capability of simulating outlet pollutant concentrations. Two and three reacting CSTRs achieved similar R2 value (0.54-0.55), whereas one reacting CSTR achieved an R2 of 0.39, and three CSTRs with reaction only in the first tank achieved an R2 of 0.42. Discretization of the nitrification rate for the case of two reacting CSTRs led to an R2 of 0.94. The parameter sensitivity analysis revealed a significant effect of model parameters on the R2 value.

Published: January 2020

In this paper, the design of a Broadband Power Amplifier for UHF applications is presented. The proposed BPA is based on ATF13876 Agilent active device. The biasing and matching networks both are implemented by using microstrip transmission lines. The input and output matching circuits are designed by combining two broadband matching techniques: a binomial multi-section quarter wave impedance transformer and an approximate transformation of previously designed lumped elements. The proposed BPA shows excellent performances in terms of impedance matching, power gain and unconditionally stability over the operating bandwidth ranging from 1.2 GHz to 3.3 GHz. At 2.2 GHz, the large signal simulation shows a saturated output power of 18.875 dBm with an output 1-dB compression point of 6.5 dBm of input level and a maximum PAE of 36.26%.
A service-oriented cloud modeling method and process
Authors: Song Chee-Yang , Cho Eun-Sook
Published: January 2020

The transition of software development from web to cloud has been accelerated. The development of cloud services requires a modeling method that reflects the characteristics of cloud including personalized service, resource sharing service, grouped and distributed services, and cross-platform operability. This study aimed to suggest a method of developing UML-based cloud services suitable for the characteristics of cloud services. A cloud service metamodel was defined using cloud applications’ characteristic modeling elements, and after that, how these cloud modeling elements are expressed into UML modeling elements was defined with an integrated metamodel between cloud and UML. By applying this hierarchical cloud metamodel, an MDA and MVC-based service-oriented cloud modeling process was established. By doing so, it will be possible to easily design services (applications) and solutions that are suitable for cloud computing environments, and in particular, to create hierarchical reuse models by the level of the abstraction of model-driven development.
Wh-Scope Marking in Japanese: Evidence for the Indirect-Dependency Approach
Authors: Fujiwara Yoshiki
Published: January 2020

The goal of this squib is to tease apart two competing approaches to wh-scope marking, the direct-dependency approach and the indirect-dependency approach, by introducing Japanese wh-scope marking. The two approaches make different predictions regarding the type of the embedded clause in wh-scope-marking constructions. The embedded clause is regarded as declarative under the direct-dependency approach but as interrogative under the indirect-dependency approach. What is especially interesting in this respect is that Japanese wh-scope marking requires the embedded clause to be marked by the interrogative complementizer ka. Japanese wh-scope marking thus provides clear morphological evidence for the indirect-dependency approach.
Jesus als Typos der Mannhaftigkeit
Authors: Weidemann Hans-Ulrich
Published: January 2020

This article examines the way Cyril of Alexandria interprets the Passion narrative in his commentary on the Gospel of John. It argues that besides the doctrinal, christological focus of his exegesis Cyril is concerned with a second issue: the contested masculinity of Jesus and his followers during the events of the Passion. This concern becomes clear when Cyril designates the cross-bearing Jesus as “the type of manly courage” (typos andreías). Following a survey of the current historical masculinity studies, the article examines Cyril’s interpretation of such scenes of the Johannine Passion account where Jesus is depicted as being arrested, beaten and flogged, humiliated and finally crucified – i.e., depicted in a way that might seem to contradict antique ideals of manliness. It finally analyzes Cyril’s explanations as to various “unmanly” or “manly” traits of Jesus’ adversaries, especially of the Jews, and of his followers: Peter, his beloved disciple and his Mother.
There’s No Place Like Home: Taiwanese Married Women in Hong Kong
Authors: Chiang Lan-Hung Nora
Published: January 2020

This study examines patterns of return migration as a background to understand the intention among marriage migrants to return to their homeland. In a five-year period beginning in 2014, the author conducted qualitative interviews with Taiwanese immigrant women in Hong Kong who had married Hong Kong men and had arrived between 1965 and 2013, to understand major aspects of their adaptation. Despite successful efforts in developing careers, establishing families, and planting new roots by becoming Hong Kongers over the last few decades, a majority of the immigrants wanted to return to Taiwan to luo ye gui gen (落葉歸根, a falling leaf finds its way to its roots). Apart from regarding Taiwan as homeland and retaining a strong sense of belonging, their desire to re-migrate to a more hospitable environment, to enjoy a better quality of life compared to that of Hong Kong, has been spelled out with narratives. Return migration remains a paradox with regard to married women who have accepted patrilocal residence at the start. Whether returns do take place remains to be seen, as return migration in essence also suggests that migration is impermanent and transnational in nature.

A new species of the genus Gonatodes (Squamata: Sauria: Sphaerodactylidae) from the western flank of the Cordillera Oriental in Colombia, with description of its hemipenial morphology
Authors: MENESES-PELAYO ELSON , RAMÍREZ JUAN P.
Published: January 2020

We describe a new sphaerodactylid lizard of the genus Gonatodes from the western flank of the Cordillera Oriental, Santander Department, Colombia based on morphological and molecular data. The new species is distinguished from all congeners by having a medium body size, by the absence of both a supraciliary spine and of clusters of distinctly enlarged conical scales on the sides and by having a subcaudal scale pattern (1’1”) and a cryptic dorsal color pattern in both sexes. Additionally, we describe for the first time the hemipenial morphology for a species of the genus. The new species increases the number of Gonatodes known from Colombia to eight and is the only known species of the country, as well as the second known mainland species of the genus not exhibiting sexual dichromatism.

Musical Lexis in Russian-Polish Lexicography: Present State and Users’ NeedsIn order to meet the expectations of receivers, who come across vocabulary from various areas in their everyday life, general bilingual dictionaries include lexis from many different fields. This article analyses one such group in Russian-Polish lexicography: musical lexis. The analysis offered here considers translation pairs extracted from two most comprehensive Russian-Polish dictionaries. The study categorises musical lexis into semantic classes and verifies the accuracy, semantic relevance and currency of provided equivalents. The aim was to establish whether general bilingual lexicography meets the needs of users looking for equivalents in this lexical area. Basing on selected material, the article also compares the structure of entries in each dictionary and considers cultural background of musical lexis in the context of Russian culture. To illustrate the issues in focus, the study comments on a number of examples and proposes some solutions to problematic cases. Leksyka muzyczna w rosyjsko-polskiej leksykografii. Stan obecny versus potrzeby użytkownikówDwujęzyczne słowniki ogólne obejmują leksykę z wielu dziedzin, wychodząc naprzeciw oczekiwaniom odbiorców, którzy w życiu codziennym stykają się ze zróżnicowanym tematycznie słownictwem. Jedną z takich dziedzin jest muzyka. Związana z nią leksyka zarejestrowana w rosyjsko-polskiej leksykografii jest obiektem naszych badań. Analiza opiera się na parach przekładowych wyekscerpowanych z dwóch najobszerniejszych słowników rosyjsko-polskich. W pracy dokonano podziału leksyki muzycznej na klasy semantyczne. Poddano weryfikacji trafność ekwiwalentów przekładowych, ich zgodność semantyczną oraz stopień aktualności terminów, zawarty w słownikach. Działania te miały na celu sprawdzenie, na ile dwujęzyczna leksykografia ogólna odpowiada potrzebom użytkowników w zakresie dostępności odpowiedników dla tego typu leksyki. Bazując na wybranym materiale, dokonano porównania budowy artykułu hasłowego w obu słownikach. Zwrócono uwagę na podłoże kulturowe leksyki muzycznej w kontekście kultury rosyjskiej. Ilustracją dla omawianych treści są liczne przykłady wraz z komentarzami oraz, niekiedy, propozycje rozwiązań kwestii problemowych.
Formy reprezentacji argumentu propozycjonalnego w bułgarskich, polskich i rosyjskich zdaniach ufundowanych na predykacie mentalnym

Forms of Representation of Propositional Argument in Bulgarian, Polish and Russian Expressions Based on the Mental PredicateThis article offers a discussion of Bulgarian, Polish and Russian mental verbs from the perspective of syntactic valence. The author examines grammatical forms of propositional argument in sentences with mental verbs which represent predicate-argument structure P (x, q). All syntactic forms in the focus of this study are classified into several patterns: observance, compression and splitting. The author demonstrates that what they involve is analogical reflection of propositional structure, greater or smaller compression of propositional argument, or its segmentation and doubling of syntactic position. The author examines the regularity of implementation of each grammatical form in Bulgarian, Polish and Russian on the basis of relevant quantitative data. Formy reprezentacji argumentu propozycjonalnego w bułgarskich, polskich i rosyjskich zdaniach ufundowanych na predykacie mentalnym Tematem prezentowanego artykułu są bułgarskie, polskie i rosyjskie czasowniki mentalne, badane w perspektywie walencji syntaktycznej. Autor analizuje gramatyczne formy realizacji argumentu propozycjonalnego w zdaniach z czasownikami mentalnymi w pozycji orzeczenia, które reprezentują strukturę predykatowo-argumentową P (x, q). Wszystkie formy syntaktyczne podzielono na kilka typów: przestrzeganie, kompresja i rozszczepienie. Autor pokazuje, że w tym zakresie mamy do czynienia z kalkowaniem struktury propozycjonalno-semantycznej, z mniej lub bardziej intensywną kompresją argumentu propozycjonalnego lub z jego rozczłonkowaniem i podwojeniem pozycji syntaktycznej. Została zbadana regularność realizacji każdej formy gramatycznej w systemie trzech języków. Wnioski są oparte na danych kwantytatywnych.

Semantics of Old Polish Beekeeping Terms: The Case of (po)łazić pszczoły/miód ‘Take Honey from the Bees’ in a Cognitive PerspectiveThis article aims to explain the process of terminologisation of the verb (po)łazić in beekeeping terminology. We present its stages and hypotheses concerning the semantics of the Old Polish term under consideration, including possible event schemas and its non-prepositional syntax. The analysis indicates that the terminologisation of word combinations with the verb (po)łazić in beekeeping terminology: (po)łazić pszczoły/miód ‘take honey from the bees’ involved the process of shifting the semantic dominant and, consequently, changing the event schema (“self-motion schema” → “caused motion schema” or “transfer”). On the level of syntactic analysis, we put forward a hypothesis about the possible origin of the non-prepositional structure generated as a result of transformation of the prepositional phrase: łazić po pszczoły/miód → połazić pszczoły/miód with a general meaning ‘perform the action directed at the singled-out object that changes its location as a result’. Semantyka staropolskich terminów bartniczych – na przykładzie (po)łazić pszczoły/miód – w ujęciu kognitywnym Celem pracy jest wyjaśnienie zjawiska terminologizacji czasownika (po)łazić w użyciu bartniczym – przedstawienie jej etapów oraz hipotez dotyczących semantyki badanego terminu staropolskiego, w tym realizowanych możliwych schematów zdarzeń, oraz jego bezprzyimkowej składni. Analiza pokazuje, że proces terminologizacji badanych połączeń wyrazowych: (po)łazić pszczoły/barć/miód polegał na przesuwaniu się dominanty znaczeniowej, a w konsekwencji zmiany schematu zdarzenia (samoprzemieszczanie → powodowanie ruchu lub przekazywanie). Z kolei w analizie składniowej badanego terminu postawiona została hipoteza o możliwym pochodzeniu konstrukcji bezprzyimkowej z przekształcenia formacji z wyrażeniem przyimkowym: łazić po pszczoły/ miód → połazić pszczoły/miód o znaczeniu ogólnym ‘wykonać daną czynność ukierunkowaną na wyróżniony obiekt, który w wyniku tej czynności zmienia swoją lokalizację’.
О роли внутренней формы слова в древних славянских переводах Библии

On the Role of the Inner Form of the Word in Historical Translations of the Bible into Slavic LanguagesThis article investigates the role of the inner form of the word in the process of translation, which is seen as a mediated form of verbal creation. Although the process of both oral and written translation has been traditionally viewed as entirely synchronic (i.e. unaffected by the deep layers of the semantic structure of the lexical unit), there are numerous examples indicating that etymologies of words may be reflected in the target text. The case in point is best illustrated with instances from historical translations of biblical texts into Slavic languages examined in this study. O roli formy wewnętrznej słowa w historycznych przekładach Biblii na języki słowiańskieNiniejszy artykuł analizuje rolę wewnętrznej formy słowa w procesie przekładu, uznawanym za zapośredniczoną formę twórczości słownej. Pomimo że proces ten, zarówno w formie pisemnej, jak i ustnej, uważa się za całkowicie synchroniczny (co oznacza, że głębokie warstwy struktury semantycznej jednostki leksykalnej nie mają na niego wpływu), istnieje wiele przykładów świadczących o tym, że etymologia słów często znajduje mniejsze lub większe odbicie w tekście docelowym. Doskonałą ilustracją tego zjawiska są przykłady pochodzące z historycznych przekładów tekstów biblijnych na języki słowiańskie, zaprezentowane w przedstawionej analizie.

“Lies”, “Dirty Madness”, “Daylight Robbery”: How Henryk Sienkiewicz Verbalised Negative Judgments and Emotions (Based on Private Correspondence)This article is part of a stream of research on the language and style of private correspondence of Henryk Sienkiewicz. The article contains analysis of expressive lexis that the writer used to verbalise his negative judgments and feelings, which is complex, rich and diverse in terms of both form and meaning. The lexical material which relates to the second – unsuccessful – marriage of Sienkiewicz to Maria Wołodkowiczówna comes from selected letters by the writer addressed to his sister-in-law – Jadwiga Janczewska neé Szetkiewicz. The selected lexis encompasses, for example, words with explicit, implicit and evaluative expression, belonging to different categories of meaning. „Kłamstwa”, „brudne szaleństwo”, „rozbój na równej drodze”, czyli jak Sienkiewicz werbalizował negatywne oceny i emocje (na podstawie korespondencji prywatnej)Artykuł wpisuje się w nurt badań nad językiem i stylem korespondencji prywatnej Henryka Sienkiewicza. Analizie poddano złożoną, bogatą i zróżnicowaną pod względem formy i znaczenia warstwę leksyki nacechowanej ekspresywnie, którą pisarz wykorzystywał do werbalizacji swoich negatywnych ocen i uczuć. Materiał leksykalny pochodzi z korpusu listów adresowanych do szwagierki – Jadwigi z Szetkiewiczów Janczewskiej, przedstawiających wydarzenia związane z drugim – nieudanym – małżeństwem Sienkiewicza z Marią Wołodkowiczówną. Wśród zebranej leksyki znalazły się np. wyrazy o ekspresji eksplicytnej i implicytnej, wartościującej, przynależnej do różnych kategorii znaczeniowych.
