Authors: Matuszewski Maciej , Słomion Małgorzata , Mazurkiewicz Adam , Pimenov Danil Yu.
Published: November 2019

This paper regards the possibility of using the degree of the surface isotropicity to assess the condition of the surface layer friction pair elements. The analysis is based on certain changes in operational and technological surface layer. The methods of constituting the surface layer have been characterized due to the features of geometric surface structure as well as the problem of assessing the condition of surface in terms of functional features and tribological characteristics.

The evaluation of the occurring changes in the surface layer have been conducted by performing tribological tests and for descript condition of surfaces the degree of surface isotropicity and weight loss of specimens have been adopted. Whereas the assessment of technological state of the surface layer has been carried out for the surface after its coating. Based on the analysis, it has been found that the use for assessment the condition of surface layer and the degree of the surface isotropicity are useful and it is an alternative way or supplement to classical adoption of a properly selected set of roughness parameters to evaluate the potential functional characteristics of friction couples surfaces.

Published: November 2019

The article is devoted to the study of the effectiveness of devices that follow the Sun. For this purpose, the construction of a two-axes tracker with an automatic system of steering the solar panels on azimuth during the light period of the day and with the possibility of manually adjusting the angle of rotation of the solar panels on the zenith, depending on the season is designed. For the proposed construction, the calculation of the angles of the zenith is made and the optimal angles are selected for manual adjustment of the seasonal positions of the system. The photo modules, which are installed stationary on the developed tracker system, are selected. Structural and electrical principle diagram of the stand was developed for determining the efficiency of solar power station, equipment was selected and its manufacture made. A solar power station monitoring system has been developed, which enables to automatically visualize parameters, perform data processing in real time, create databases and perform a comparative analysis of their operational efficiency in an automatic mode. Experimental researches have been carried out on determination of the generated electric energy by static and dynamic solar power stations, on the basis of which the efficiency of tracker systems of rotation of solar panels is confirmed. The use of dynamic systems compared to static allows to increase the production of electricity by 33% under the same conditions. But with poor illumination of the panels (rain, fog, cloudy weather), the tracker's effectiveness decreases and it does not exaggerate 5% when fully covered with the sky. Therefore, the use of tracking systems in the absence of direct sunlight on the surface of photo modules is not feasible.
P-type transport ATPases inLeishmaniaandTrypanosoma
Authors: Meade John C.
Published: November 2019

P-type ATPases are critical to the maintenance and regulation of cellular ion homeostasis and membrane lipid asymmetry due to their ability to move ions and phospholipids against a concentration gradient by utilizing the energy of ATP hydrolysis. P-type ATPases are particularly relevant in human pathogenic trypanosomatids which are exposed to abrupt and dramatic changes in their external environment during their life cycles. This review describes the complete inventory of ion-motive, P-type ATPase genes in the human pathogenic Trypanosomatidae; eightLeishmaniaspecies (L.aethiopica,L.braziliensis,L.donovani,L.infantum,L.major,L.mexicana,L.panamensis,L.tropica),Trypanosoma cruziand threeTrypanosoma bruceisubspecies (Trypanosoma brucei bruceiTREU927,Trypanosoma bruceiLister strain 427,Trypanosoma brucei gambienseDAL972). The P-type ATPase complement in these trypanosomatids includes the P1B(metal pumps), P2A(SERCA, sarcoplasmic-endoplasmic reticulum calcium ATPases), P2B(PMCA, plasma membrane calcium ATPases), P2D(Na+pumps), P3A(H+pumps), P4(aminophospholipid translocators), and P5B(no assigned specificity) subfamilies. These subfamilies represent the P-type ATPase transport functions necessary for survival in the Trypanosomatidae as P-type ATPases for each of these seven subfamilies are found in allLeishmaniaandTrypanosomaspecies included in this analysis. These P-type ATPase subfamilies are correlated with current molecular and biochemical knowledge of their function in trypanosomatid growth, adaptation, infectivity, and survival.
Confirming geomagnetic Sfe by means of a solar flare detector based on GNSS
Authors: Curto Juan José , Juan José Miguel , Timoté Cristhian Camilo
Published: November 2019

Solar Flares (SF) refer to sudden increases of electromagnetic radiation from the Sun lasting from minutes to hours. Irradiance in the Extremely Ultra-Violet (EUV) or X band is enhanced and it can produce a sudden over-ionization in the ionosphere, which can be tracked by several techniques. On the one hand, this over-ionization increases the ionospheric delays of GNSS signals in such a way as can be monitored using measurements collected by dual-frequency GNSS receivers. On the other hand, this over-ionization of the ionosphere is the origin of electrical currents which, in turn, induce magnetic fields which can be monitored with ground magnetometers. In this work we propose the use of a GNSS Solar Flare Monitor (GNSS-SF) for its utility to confirm the presence of ionospheric ionization which is able to produce Solar Flare Effects (Sfe) in geomagnetism. A period of 11 years (2008–2018) has been analyzed and contingency tables are shown. Although most of the GNSS-SF detections coincide with SF and most of the Sfe have a detected origin in the ionosphere, there are some paradoxes: sometimes small flares produce disturbances which are clearly detected by both methods while other disturbances, originated by powerful flares, go by virtually unnoticed. We analyzed some of these cases and proposed some explanations. We found that suddenness in the variation is a key factor for detection. Threshold values of the velocity of change to remove the background noise and the use of the acceleration of change instead of the velocity of change as the key performance detector are other topics we deal with in this paper. We conclude that the GNSS-SF detector could provide warnings of ionization disturbances from SF covering the time when the Sfe detectors are “blind”, and can help to confirm Sfe events when Sfe detectors are not able to give a categorical answer.

Published: November 2019

Craniomaxillofacial gunshot injuries, resulting from assault, suicide attempts, and accidental trauma, represent a major public health dilemma in the United States. Due to the extent of injury and resulting osseous and soft tissue loss, facial gunshot wounds pose a unique challenge to the reconstructive surgeon. Initial management should use advanced trauma life support principles with the goal of patient stabilization. Acute operative management should center around wound decontamination, debridement, and temporary closure. Historically, definitive surgical management focused on delayed reconstruction secondary to high rates of wound infections, necrosis, and ischemia. With improvements in imaging modalities, the advent of virtual surgical planning, and the popularization of microvascular free flaps, contemporary methods have shifted toward earlier more definitive reconstruction. Autologous free tissue transfer has resulted in a decrease in hospital stay and the number of overall surgeries. Importantly, due to the variability in injury pattern and complexity in reconstruction, a systematic approach toward intervention is needed to mitigate complications and optimize overall functional and aesthetic outcomes.

Objective This study was aimed to provide a key update to the seminal works of Prof. Albert L. Rhoton Jr., MD, with particular attention to previously unpublished insights from the oral tradition of his fellows, recent technological advances including endoscopy, and high-dynamic range (HDR) photodocumentation, and, local improvements in technique, we have developed to optimize efficient neuroanatomic study.

Methods Two formaldehyde-fixed cadaveric heads were injected with colored latex to demonstrate step-by-step specimen preparation for microscopic or endoscopic dissection. One formaldehyde-fixed brain was utilized to demonstrate optimal three-dimensional (3D) photodocumentation techniques.

Results Key steps of specimen preparation include vessel cannulation and securing, serial tap water flushing, specimen drainage, vessel injection with optimized and color-augmented latex material, and storage in 70% ethanol. Optimizations for photodocumentation included the incorporation of dry black drop cloth and covering materials, an imaging-oriented approach to specimen positioning and illumination, and single-camera stereoscopic capture techniques, emphasizing the three-exposure-times-per-eye approach to generating images for HDR postprocessing. Recommended tools, materials, and technical nuances were emphasized throughout. Relative advantages and limitations of major 3D projection systems were comparatively assessed, with sensitivity to audience size and purpose specific recommendations.

Conclusion We describe the first consolidated step-by-step approach to advanced neuroanatomy, including specimen preparation, dissection, and 3D photodocumentation, supplemented by previously unpublished insights from the Rhoton fellowship experience and lessons learned in our laboratories in the past years such that Prof. Rhoton's model can be realized, reproduced, and expanded upon in surgical neuroanatomy laboratories worldwide.
2.1.3 Gold/Organocatalyst Dual Catalysis
Authors: Shi X. , Wang J.
Published: November 2019

Since the beginning of the 21st century, gold catalysis and organocatalysis have become two important branches in modern synthetic methodology thanks to the tremendous efforts the synthetic chemistry community have devoted to these two fields. While gold catalysis demonstrates superior capability in the activation of C-C multiple bonds, organocatalysis has been a remarkable tool for the activation and functionalization of carbonyl compounds, such as aldehydes and ketones, in a stereoselective fashion. Combining these two powerful, yet complementary, catalytic modes in a dual-catalytic manner will lead to even more-efficient and sophisticated catalytic systems and, thus, dual gold/organocatalysis has become a hot topic in the past decade. In this chapter, a summary of reported examples of dual gold/organocatalysis are discussed, including gold/aminocatalysis, gold/Brønsted acid catalysis, and gold/hydrogen-bonding catalysis.
2.4 Organocatalyst/Photocatalyst Dual Catalysis
Authors: Zeitler K.
Published: November 2019

Recent advances in dual-catalytic methods combining organocatalysis with (visible-light) photocatalysis are detailed within this chapter. It summarizes general aspects together with selected state-of-the-art procedures, highlighting both pioneering examples and current developments.

The merger of organocatalysis with photocatalysis has proven to be enormously powerful, not only because it provides a synthetic platform to readily access radical intermediates within an organocatalytic manifold and its potential to alter the reactivity of typical organocatalytic intermediates, but also due to the new opportunities in asymmetric synthesis. The synergistic dual combination with organocatalysis enables photocatalytic reactions to be conducted in an enantioselective fashion and thereby has had a profound influence on several fields of current chemical research, including radical chemistry.

We consider a fibre laser system generating ∼10-μJ, ∼500-fs pulses with a peak power of ∼10 MW at a repetition rate of 100 kHz and emission wavelength of 1.56 μm. The system is based on a master oscillator – power amplifier configuration. The amplifier ensures chirped-pulse amplification. The pulses are then compressed by a dispersive grating compressor. The output amplifier stage is based on a specially designed tapered large mode area erbium-doped fibre for suppressing nonlinear effects. The experimental data agree with numerical simulation results for the stretcher, amplifier and compressor. The stretcher and amplifier have been simulated using a generalised nonlinear Schrödinger equation. In addition, numerical simulation results suggest that optimising the stretcher and compressor will potentially allow the peak power of the system to be scaled up to ∼30 MW.

Published: November 2019

The influence of the width of pump pulses (with λ
p = 1.026 μm) on the SRS generation of femtosecond pulses in a methane-filled hollow-core fibre is investigated. The width of pump pulses is controlled by transmitting them through an optical dispersion-managed system and thus making them linear frequency-modulated (chirped). Regimes of both the preferred SRS generation of femtosecond pulses at the Stokes wavelength (λ
st = 1.464 μm) and the generation of a multiband supercontinuum are experimentally demonstrated. A quantum efficiency of 41 % and a pulse width of 590 fs at the Stokes wavelength are obtained for the 1.026 → 1.464 nm Raman generation.

Costs and benefits of towed videos and remotely operated vehicles for sampling shallow reef habitats and fish
Authors: Davis T. R. , Cadiou G. , Williams J. , Coleman M. A.
Published: November 2019

Where several different tools are available for research, the costs and benefits associated with each option become an important part of the selection process. Towed video (ToV) and remotely operated vehicles (ROVs) are both widely used to assess shallow reef benthic habitats and fish assemblages, but quantitative data on their comparative performance is limited. The relative abilities of commercially available ToV and ROV were assessed using two low-cost (less than A$10000), manually deployable systems. These systems were deployed to collect photographs of marine habitats and videos of fish assemblages along six 200-m transects at three separate sites. The time required to operate each system and the specific limitations and advantages of each system were compared. Both systems performed equally in terms of the resolution of data collected on benthic habitats and fish assemblages on shallow reefs. However, ToV required significantly less time (~60% less) to collect data than ROV, and should allow cost savings with no loss in data quality. We recommend ToV as a cost-effective and easily deployable system for assessing rocky reef habitats and fish assemblages.

Published: November 2019

To elucidate the role of POU2F2 (POU class 2 homeobox 2) in fracture healing, 30 rats with femoral fracture were randomly grouped into three groups: FF group, LV-POU2F2 group and LV-scramble group. Rats were injected with PBS, lentivirus expressing POU2F2 or scramble lentivirus once a week for 4 weeks. Results showed that overexpressing of POU2F2 promoted fracture healing and callus growth. Besides, overexpressing of POU2F2 promoted protein and mRNA expression of Col10a1, Runx2, Osterix, and Osteocalcin. High Mobility Group AT-hook 1 (HMGA1) is a non-histone protein participating in chromatin remodeling of cells. Western blotting manifested HMGA1/Wnt/β-catenin pathway was activated in POU2F2 group. Moreover, in-vitro study of hMSCs cells supported the above data. In conclusion, POU2F2 promotes fracture healing via activating the HMGA1/Wnt/β-catenin signaling pathway.

Extracellular vesicles (EVs) have sparked tremendous interest owing to their prominent potential in diagnostics and therapeutics. Isolation of EVs from complex biological fluids with high purity is essential to the accurate analysis of EV cargo. Unfortunately, generally used isolation techniques do not offer good separation of EVs from non‐EV contaminants. Hence, it is important to have a standardized method to characterise the properties of EV preparations, including size distribution, particle concentration, purity and phenotype. Employing a laboratory‐built nano‐flow cytometer (nFCM) that enables multiparameter analysis of single EVs as small as 40 nm, here we report a new benchmark to the quality and efficiency assessment of EVs isolated from plasma, one of the most difficult body fluids to work with. The performance of five widely used commercial isolation kits was examined and compared with the traditional differential ultracentrifugation (UC). Two to four orders of magnitude higher particle concentrations were observed for EV preparations from platelet‐free plasma (PFP) by kits when compared with the EV preparation by UC, yet the purity was much lower. Meanwhile, the particle size distribution profiles of EV preparations by kits closely resembled those of PFP whereas the EV preparation by UC showed a broader size distribution at relatively large particle size. When these kits were used to isolate EVs from vesicle‐depleted PFP (VD‐PFP), comparable particle counts were obtained with their corresponding EV preparations from PFP, which confirmed again the isolation of a large quantity of non‐vesicular contaminants. As CD9, CD63 and CD81 also exist in the plasma matrix, single‐particle phenotyping of EVs offers distinct advantage in the validation of EVs compared with ensemble‐averaged approaches, such as Western blot analysis. nFCM allows us to compare different isolation techniques without prejudice.
Metabologically active hydrolytical microbial communities of soil ecosystems under influence of soil physical factors

Published: November 2019

Application of molecular biological techniques in environmental studies provides a more complete information concerning the taxonomic diversity and potential hydrolytic activity of soil microbial complexes that exist in a wide range of environmental factors. Among the key environmental parameters that determine the functional activity of the hydrolytic complex of soil layer, the most significant one is moisture. Moisture levels providing maximum activity of a hydrolytic microbial complex depend on the soil type. At high levels of moisture and temperature, the role of prokaryotic organisms, mainly actinomycetes, in the microbial complex significantly increases. It was discovered a new functional activity of actinomycetes in the hydrolytic prokaryotic complex: their controlling influence on the respiratory level of the complex in a wide range of parameters (moisture, organic matter, successional time).At the optimum for the life of most microorganisms levels of moisture (60% of field capacity) and temperature (27°C), representatives of Firmicutes and Actinobacteria phylums stand out among chitinolytic and pectinolytic dominants of the studied soils within the Bacteria domain. With increasing moisture and decreasing temperature the proportion of Proteobacteria increases. With decreasing moisture and increasing temperature, there is an increase in the amount of unicellular actinobacteria.
Comparison of four classical algorithms to determine the apparent thermal diffusivity of heavy clay soil in field and laboratory column experiments
Authors: Mikailsoy F D , Shein E V
Published: November 2019

Prediction of soil temperature at an acceptable level of accuracy is essential for managing soil temperature at large scales since its measurement is costly and not practical due to its high spatial and temporal variability. This study was carried out for:: 1) Calculate the coefficient of thermal conductivity using classical methods and basing on data from measured soil profile temperatures in column and field conditions and 2) compare the results of the calculated and measured soil temperature, calculated from these data for both conditions. Soil temperature was measured with thermal sensors on both soil profiles in the field and soil column. The measured temperature values were similar in soil column and profile across 0.05, 0.10, and 0.20 m depths, but had the difference for 0.30 cm. The introduction of the second harmonic allows determining with high accuracy the parameters (T0, Ti, εi) of the temperature distribution on the field and column soils surfaces. For example, respectively for the harmonics n = 1 calculated the following statistical characteristics: R2 = 86.45%, σ = 3.26, A = 13.07%, UII=0.12 and for n = 2: R2 = 98.64%, σ = 1.09, A = 4.20%, UII=0.04. It was found that, mean values for soil thermal diffusivity (k), thermal conductivity (λ), damping depth (d) and heat absorptivity (e), calculated by amplitude, arctangent and logarithm methods, for the column were greater than those for soil profile, in all the cases.

Reserves of energy saving and reduction of oil recovery costs
Authors: Kolesnik S V , Krivova N R
Published: November 2019

The paper considers the use of controlled drive for oil recovery and pressure maintenance, which represents the oscillating system (sucker-rod pump drive) and adjustable drive of a pump unit (for pressure maintenance system) thus making it possible to reduce power consumption through oil recovery by 25…30 %. The development of electric drives, increase of their controllability, reduction of energy losses is considered alongside with the method of rotation speed control by redistribution of angular speed and power flows through a differential. In order to provide modern technological systems with cost efficient electric drives controlled by speed in a wide range with constant power on the output shaft, the new control principle (birotating) can be considered promising due to economy, simple design, low cost caused by lack of power electronics and high reliability.
Risks of long-term leasing transactions for construction industry development
Authors: Barykina Yuliya
Published: November 2019

The article examines potential long-term leasing risks for development of the construction industry, characterizes leasing as a form of investment. Leasing objects of the construction industry were identified. Methods for minimizing risks were considered. Leasing companies and large construction companies rarely lease out equipment to private, small-sized construction companies facing general and specific risks. The degree of risk depends on the leasing object (e.g., equipment that cannot be disassembled, rare equipment, expensive equipment which is difficult to sell at an affordable price). The problem to be solved is lack of owned funds for carrying out innovation activities. The article describes funding methods for innovation activities of manufacturing enterprises. It has been found that the most common funding method is leasing. Innovation activities of enterprises are a number of measures aimed to search for, commercialize and implement scientific knowledge, new technology and inventions. Currently, innovation activities influence the Russian economy by enhancing efficiency of resource management, creating new industries, infrastructure and jobs. Under the global competition, the effects of innovation activities on national development and competitiveness are becoming more intensive.
State programs on provision of population with affordable and comfortable housing: an issue of efficient implementation
Authors: Grushina Olga , Shelomentseva Natalya
Published: November 2019

the paper deals with the issue of state-supported provision of the population with affordable and comfortable housing. Over the last decade the organizational and economic mechanism of state participation in solving social problems involves mainly development, approval and implementation of various state programs. In the present paper, evolution of the state programs in the field of affordable housing adopted since 1991 is discussed in detail. The goals and objectives of the programs, target indicators and their changes over time, and the possibility of their attaining are critically analyzed. The authors have tried to find ways to assess the efficiency of the state programs implementation from the point of view of those for whom they are devoted to, i.e. citizens who need to improve their living conditions. Some indicators for assessing the dynamics of changes in the number of households that are in need of housing and meeting the requirement of the programs are calculated. The analysis shows that the state programs are of low efficiency for those whose housing problems should be solved. The applied methods for evaluating the efficiency of state programs exist “per se”, and for the management they are considered as quite satisfactory. However, in the Irkutsk region, the effectiveness of housing state programs in accordance with the applied methodology for 2015-2017 is only 70-80%. Recommendations for improving the efficiency of state programs should be made in two directions: (i) improvement of the budget planning of the region and (ii) improvement of the target indicators of the programs.

The article analyzes the required institutional framework for smart specialization implementation. Propositions are made on how Russian institutions in the fields of innovations and regional development can adapt to further the smart specialization agenda. The article concludes with the analysis of the draft strategy for social and economic development of the Irkutsk oblast from the point of view of its conformity with the criteria of smart specialization. Specific guidelines are outlined for the improvement of the strategy in this respect.

Published: November 2019

This paper presents results of performance comparison and common conclusions about low-water demand cements (LWDC) which were developed in USSR in 1980-ies. Using technology of this composite binders allows to dramatically decrease CO2 emission without loss of performance. In current study different parameters of production have been studied such as types of admixtures, mineral fillers, workability parameters, e.g., milling ability with superplasticizers solutions as grinding agents and compressive strength. It is set that during first period of grinding any cement systems which contain water will perform lowered grinding ability, but after some tine this parameter begins to grow and up to values, equal to systems without water. This fact makes possible to use, e.g. water solutions of PCE, and allows to decrease cost of LWDC in order to make it cost-effective.

The article describes the causes enough active use of the mechanism of the mortgage in order to resolve housing issues. It emphasizes that the problem of formation and development of the property market and the use of such forms of financing investments in real estate as mortgage lending is one of the most urgent today. In this regard, using the experience of developed countries, conclusions about the prospects of development of legal institutions in our country. Consideration of a mortgage as an intangible resource has a high degree of relevance in terms of further regulating mortgage as a banking product, as well as selecting the direction of development of state policy in the field of residential construction.
Legal protection of BIM products

Published: November 2019

Science and technology are developing faster than intellectual property legislation. As a result, previously unknown products of intellectual activity are regulated by general rules. These objects are BIM products. The use of BIM technology in the construction industry involves creation of a three-dimensional model filled with architectural, design, technological, economic and other data about a building considered as a single object. The BIM product may include several intellectual property objects regulated by different laws (e.g., databases and design inventions, know-how, etc.). The legislation of the Russian Federation does not define the concept “BIM products”. There are no integrated objects taking into account its features. It is not possible to apply Article 1240 of the Civil Code of the Russian Federation to the BIM products. The list of intellectual property objects is limited. It is necessary to include BIM products into Article 1240 of the Civil Code of the Russian Federation.

Modern organic electronic and power electronic devices gained attention due their superior performance and efficiency with reduced cost. While nanocomposites of these organic semiconductors have high potential to further enhance these properties. In this work, thin films of zinc oxide-polyaniline (ZnO-PANI) nanocomposite with different compositions of ZnO (50, 60 and 70 wt%) are deposited by spin coater onto the surface of p-Si. The phase identification of the samples is identified through x-ray diffraction analysis. Pure ZnO showed wurtzite crystalline while PANI and nanocomposites of ZnO-PANI showed amorphous structure. The optical absorption band gap was evaluated from Ultraviolet–visible spectroscopy absorption studies and band gaps were calculated from Tauc’s plots. The Ultraviolet–visible spectroscopy showed that by increasing ZnO content in the nanocomposite, the band gap increases from 3.25 eV to 3.3 eV and 3.4 eV for 50–50, 60–40 and 70–30 wt% respectively. The AC electrical properties of the nanocomposites were studied by using impedance spectroscopy. The parameters extracted from the impedance plots and conductivity values showed that 50–50 wt% is more conductive while that of 70%–30% wt is more resistive.
Not Being Able to Speak Is Torture: Performing Listening to Painful Narratives
Authors: Sotelo Castro Luis Carlos
Published: November 2019

This Note discusses a new creative approach to intervene in the interaction between survivors who contribute their memories of a painful past and the public they want to reach. It proposes that by turning both the narrator and the public into performers of listening, they are placed in a relational context that offers an alternative space in which victims’ and the public’s memories, emotions and thoughts in a transitional context can be worked through. The method thereby corrects the notion of the public as a disembodied, virtual totality underlying state-led transitional justice institutions.
Human Rights at the Time of Transition: How Security Forces Can be Held Accountable in a Divided Community?
Authors: Qafisheh Mutaz M
Published: November 2019

The Palestinian Authority has established various mechanisms to monitor its security forces and hold them accountable over human rights violations. This article explores and assesses the accountability measures that deal with the human rights abuses arising from the excessive use of force in light of international standards, particularly human rights treaties that Palestine has acceded to in recent years. The use of force may occur in different contexts, including during demonstrations, while enforcing the law against criminal acts, searches, lawlessness, in detention, interrogation, investigation and in prisons. The article traces the accountability processes that arise in such circumstances. Alongside reviewing domestic legislation and cases as well as citing relevant literature, the article employs empirical qualitative field research approach by conducting a series of interviews with senior security officials, particularly top commanders and those in charge of accountability within the government and security agencies along with NGOs, experts, academics and field-based international institutions.

The black soldier fly (BSF, Hermetia illucens (Linnaeus), Diptera: Stratiomyidae) is an edible insect widely reared by using various types of organic wastes as its diet. Developing tools to evaluate the growth performance of BSF is crucial for improving its production. In this study, we monitored the daily growth of BSF larvae reared with 10 diets with diverse nutritional quality and compared 7 growth models for quantifying growth performance. We found that BSF generally exhibited an S-shaped growth curve and that the Richards model was the best-fitting growth model. We estimated asymptotic growth limit (W∞) and constructed a time-series curve of absolute growth rate (AGR) by using the Richards model. We used Gaussian functions to estimate AGR parameters (maximum AGR, m; timing of maximum AGR, T; the deviation of AGR, d) to evaluate whether these parameters adequately quantify the growth performance of BSF. Correlation analysis showed that the AGR parameters were mostly independent of W∞ but were correlated with the duration of the larval stage, indicating that W∞ and the AGR parameters respond to different dietary factors. The results of pairwise comparisons showed that the diets rich in carbohydrates and protein had high W∞, m, and d, and early T. The diets with low levels of carbohydrates had low W∞, and the diets with low levels of protein had low m and d and delayed T. We conclude that the parameters estimated by the Richards model could be effective indices for evaluating the growth performance of BSF and their diet quality.

Angiosarcoma is a rare malignant tumour, which accounts for 1–2% of all malignant soft-tissue tumours. Most cases of angiosarcoma arise spontaneously, and malignant transformation of vascular malformation to angiosarcoma is extremely rare. We describe the case of a 70-year-old woman with a massive arteriovenous malformation in her shoulder, which gradually enlarged, despite repeated surgeries and radiation therapy over 53 years. She also presented with rapidly growing haemorrhagic masses in her oral cavity. Excision biopsy was performed, and the pathohistological diagnosis was angiosarcoma. Positron emission tomography–computed tomography revealed high fluorodeoxyglucose accumulation in the oral cavity and right shoulder, the latter of which was consistent with the location of the arteriovenous malformation. The masses in the oral cavity were diagnosed as metastatic angiosarcoma from the right shoulder, where the massive arteriovenous malformation was suspected to have malignantly transformed. This report describes a possible case of malignant transformation of arteriovenous malformation to angiosarcoma.
