Authors: Valkov Georgi , Nikolov Valyo 
Published: July 2020

Abstract
The outcome of studying the strength and the deformation characteristics of rough terrain forklifts, using a created 3D model applying FEM, is presented herein. The tested chassis design features are described. The external loads of the chassis structure have been estimated throughout two operation modes: handling the load at vertically elevated lifting mast and also featuring load lifted off the ground, using lifting mast in transport mode tilted backwards. Two alternating payloads have been applied for each of the selected modes: featuring reated load and standard size of the centre of gravity, and featuring reduced load at increased height of the centre of gravity. The resulting rates of stresses and deformations of the studied chassis of a rough terrain forklift have been calculated, presented and analysed with regard to the two main operating modes both of which entail two loading alternatives determined by the weight and the location of the payload.
Graph-analytic approach to determine the position of the initial impact in the event of pedestrian accidents
Authors: Savova-Mratsenkova Milena , Palagachev Georgi 
Published: July 2020

Abstract
In the present research the authors propose a graph-analytic approach to determine the position of the initial impact in the event of pedestrian accidents. When investigating the velocity of movement of the vehicle (participating in the accident), mechanics theorems and parameters are used, which are reported in a scheme and are consistent with the data, gathered from the scene of the accident. The present study uses case law data from a real road traffic accident. The proposed approach can find wide application in the practice of pedestrian accident reconstruction in the absence of specific data that uniquely identify the exact location in the lane in which the initial impact between the vehicle and the pedestrian had happened.

Authors: Angelova Radostina A , Velichkova Rositsa 
Published: July 2020

Abstract
Surgical gowns and medical clothing have to protect the surgeons from the patient and vice versa. However, all players in the operating room (OR) have to be in a state of thermophysiological comfort. The comfort of the surgeons is of special importance, as they are exposed to stressful situations, which could influence their performance negatively. The study presents an analysis of the thermophysiological comfort of the surgeons in an OR, using protective clothing ensembles with different clothing insulation and protection: a surgical scrub suit (SSS) and a clean air suite (CAS). The analysis is based on the calculation of PMV-PPD indexes, following Fanger’s model. Different combinations of thermal environment parameters and clothing insulation are tested and analysed.

Authors: Konstantinova Snezhinka , Konarev Asen 
Published: July 2020

Abstract
This report examines the impact of investment in intangible assets on corporate growth of public industrial companies. An intangible asset growth indicator model has been developed. A new conceptual approach for measuring corporate growth has been implemented, using an integral indicator determined by four single indicators using weighted geometric mean model. Based on built models, a study has been conducted to show that the companies have achieved moderate corporate growth, accompanied by faster growth in intangible assets. Investments in intangible assets are proven to be a stable factor for corporate growth. Bulgarian industrial companies do not sufficiently utilize the intangible assets of leading companies. The investment strategy of Bulgarian companies should be optimized primarily to achieve a spillover effect.

Published: July 2020

AbstractExtraordinary optical, electrical and chemical properties of 2D materials have potential to be useful for quick and sensitive detection of pathological diseases. One important example is malaria disease that can progress rapidly and cause death within days. Therefore, fast, accurate and cost-effective malaria diagnosis available at the point of care is urgently needed to facilitate precise treatment. Here we report rapid and highly sensitive malaria detection with an inexpensive graphene-protected copper surface plasmon resonance biosensor. Using phase sensitive surface plasmon resonance technique and a graphene functionalization protocol for attaching end-tethered DNA probes that were complementary to a malaria specific DNA target, we were able to significantly improve the detection limit of the malarial plasmodium parasite. The phase sensitivity of our graphene-enhanced sensors exceeds by two orders of magnitude the sensitivity of analogous optical biosensors. This enhanced sensitivity could provide means to detect low copy number bacterial infectious agents and to associate dormant bacterial populations with chronic inflammatory diseases using simple label-free optical detection.

Abstract
The microstructure and electrochemical properties of a novel cathode Nd0.5Sr0.5Co0.5Mn0.5O3-δ
were discussed in the paper. After calcination at 1000 °C, a perfect single crystal was obtained. Some diffraction streaks along [200] and [112] patterns in HR-TEM appeared for the ordering of oxygen vacancies, or as the overlap of B-site cations (Co2+/Co3+ and Mn2+/Mn3+) with stacking fault-derived scattering of ordering. Area-specific resistance (ASR) was 0.023 Ω · cm2 when Nd0.5Sr0.5Co0.5Mn0.5O3-δ
was deposited on the electrolyte as the electrode at 700 °C in air. The maximum power density and the maximum OCV were 592.80 mW·cm−2 at 650 °C and 0.89 V at 550 °C for a single cell, respectively. Hence, the material Nd0.5Sr0.5Co0.5Mn0.5O3-δ
could be considered as an air-electrode in Intermediate-temperature solid oxide fuel cells (IT-SOFC).

Abstract
Noble metals nanoparticles (NMNPs) due to unique physical and chemical properties have attracted intense scientific interest for wide applications. Nanosphere lithography demonstrates a feasible strategy to achieve various metal nanostructures. In this paper, ZnO array is fabricated by magnetron sputtering method based on self-assemble polystyrene spheres (PSs) array. The thermal decomposition is used to achieve ZnO shell arrays by removing polystyrene spheres (PSs). The size of ZnO shell arrays can be controlled by changing the size of PS spheres. Disordered Au nanoballs coated on ZnO shell array are fabricated by electron beam deposition and the thermal decomposition to enhance optical properties of ZnO shell array. Optical properties, Morphology and chemical composition of Au nanoballs coated on ZnO shell array are analyzed by UV–vis Spectrophotometer, SEM and XRD. Based on localized surface plasmon resonance (LSPR) of the metal nanoparticles, the optical properties of ZnO shell array are enhanced by disordered Au nanoballs. Hence, it can be potentially applied in related optoelectronic devices.

Published: July 2020

Abstrast
Low carbon steel was suitable for industrial fields due to its low price, wide application range and excellent comprehensive performance. However, there were still shortcomings such as poor wear resistance and corrosion resistance in special occasions. In hence, this paper carried out a study on the strengthening process of low-carbon steel parts surface deposition. The TIG welding arc welding method was used to study the strengthening performance of the arc-enhanced medium entropy alloy additive layer. To analyze the elements and microstructure of the medium entropy alloy additive layer by x-ray diffractometer(XRD), scanning electron microscope (SEM), energy dispersive spectrometer (EDS) and other modern analysis methods. The micro-hardness, friction and wear and electrochemical corrosion detection methods were used to study the friction and wear and corrosion resistance of the medium entropy alloy additive layer. The results show that the microstructure of the medium entropy alloy additive layer is a typical lamellar pearlite, which is wrapped with face-centered cubic solid solution (FCC) and unevenly distributed in the additive layer. The microhardness of the medium entropy alloy additive layer is significantly higher than that of the substrate. As the friction and wear load increases, the friction coefficient of the medium entropy alloy additive layer gradually decreases. The wear rate of the additive layer is much lower than that of the substrate and the wear resistance is doubled compared to the substrate. The form of wear is mainly abrasive wear and fatigue spalling wear. The medium entropy alloy additive layer has excellent corrosion resistance. Its corrosion rate is about one tenth of the substrate. The arc cladding medium entropy alloy powder core wire can meet the surface strengthening requirements of low-carbon steel parts and provide engineering basis for the low-carbon steel large-scale, multi-domain, high-level application.
Characterization of novel 3D printed plastic scintillation dosimeters
Authors: Lynch Nicholas , Monajemi Thalat , Robar James L 
Published: July 2020

Abstract
We propose a new methodology for the fabrication and evaluation of scintillating detector elements using a consumer grade fusion deposition modeling (FDM) 3D printer. In this study we performed a comprehensive investigation into both the effects of the 3D printing process on the scintillation light output of 3D printed plastic scintillation dosimeters (PSDs) and their associated dosimetric properties. Fabrication properties including print variability, layer thickness, anisotropy and extrusion temperature were assessed for 1 cm3 printed samples. We then examined the stability, dose linearity, dose rate proportionality, energy dependence and reproducibility of the 3D printed PSDs compared to benchmarks set by commercially available products. Experimental results indicate that the shape of the emission spectrum of the 3D printed PSDs do not show significant spectral differences when compared to the emission spectrum of the commercial sample. However, the magnitude of scintillation light output was found to be strongly dependent on the parameters of the fabrication process. Dosimetric testing indicates that the 3D printed PSDs share many desirable properties with current commercially available PSDs such as dose linearity, dose rate independence, energy independence in the MV range, repeatability, and stability. These results demonstrate that not only does 3D printing offer a new avenue for the production and manufacturing of PSDs but also allows for further investigation into the application of 3D printing in dosimetry. Such investigations could include options for 3D printed, patient-specific scintillating dosimeters that may be used as standalone dosimeters or incorporated into existing 3D printed patient devices (e.g. bolus or immobilization) used during the delivery of radiation therapy.
Advancing energy poverty measurement for SDG7
Authors: Pachauri Shonali , Rao Narasimha D 
Published: July 2020

Abstract
Existing indicators used to track progress towards achieving target 7.1 of the sustainable development goals (SDGs) narrowly interpret energy poverty as a lack of connections. Recently proposed measurement frameworks are multidimensional, but complex and conceptually muddled. We propose an alternative framework that simplifies and distinguishes two conceptually distinct aspects of energy access—energy supply conditions and the status of household energy poverty. This approach, with refinements through further applications to real data, can improve the design and targeting of policies to both service providers and vulnerable groups to accelerate affordable and reliable energy service provision.
Traffic flow splitting from crowdsourced digital route choice support
Authors: Storch David-Maximilian , Schröder Malte , Timme Marc 
Published: July 2020

Abstract
Digital technology is fundamentally transforming human mobility. Route choices in particular are greatly affected by the availability of traffic data, increased connectivity of data sources and cheap access to computational resources. Digital routing technologies promise more efficient route choices for the individual and a reduction of congestion for cities. Yet, it is unclear how widespread adoption of such technologies actually alters the collective traffic flow dynamics on complex street networks. Here, we answer this question for the dynamics of urban commuting under digital route choice support. Building on the class of congestion games we study the evolution of commuting behavior as a fraction of the population relies on, but also contributes to, crowdsourced traffic information. The remainder of the population makes their route choices based on personal experience. We show how digital route choice support may cause a separation of commuter flows into technology and non-technology users along different routes. This collective behavior may fuel systemic inefficiencies and lead to an increase of congestion as a consequence. These results highlight new research directions in the field of algorithmic design of route choice decision support protocols to help fight congestion, emissions and other systemic inefficiencies in the course of increasing urbanization and digitization.

Published: July 2020

Abstract
Phytofabrication of Zinc Oxide nanoparticles (ZnO–NPs) through Nephelium lappaceum L. and Garcinia mangostana L. plants’ wastes were achieved as an environmentally friendly method of synthesizing nanoparticles. Biogenic ZnO–NPs were characterized by Ultra Violet Visible (UV–vis) spectrophotometry, Scanning Electron Microscope (SEM), Transmission Electron Microscope (TEM), Energy Dispersive Energy (EDX ), and Fourier Transform Infrared spectroscopy (FTIR). UV- Visible absorption of ZnO–NPs indicated a characteristic absorption band at 362–368 nm region. The synthesized nanoparticles were flower in shape, as shown by the SEM images, and they were further elucidated by the TEM images. ZnO-NP synthesized via Rambutan Peel Extract (RPE), Rambutan Seed Extract (RSE), Mangosteen Peel Extract (MPE) and Mangosteen Seed Extract (MSE) showed the average particle size of 29 nm–184 nm, 86 nm–260 nm, 92 nm–247 nm, and 233 nm–334 nm respectively. FTIR spectra demonstrated peaks at 3269–3500 cm−1, 2308–2361 cm−1, 2103–2110 cm−1 and 1630–1640 cm−1, 586–632 cm−1 for the plant extracts, whereas an additional peak appeared within the range of 458–499 cm−1 in ZnO–NPs spectra. The photocatalytic activity of the synthesized ZnO–NPs was measured by the degradation of Methylene Blue under sunlight. The highest degradation of Methylene Blue dye was detected in ZnO—NPs synthesized using the seed extract of Nephelium lappaceum L., where a Half-life of 78 min and 97% degradation efficiency at 150 min time frame was observed. The ZnO–NPs were identified to possess fluorescence quenching ability of Rhodamine B. The highest quenching ability was recorded in ZnO–NPs synthesized via Garcinia mangostana L. seed. The Photoluminescence study showed that the intensity of spectral lines of biogenic ZnO–NPs were higher compared with the chemically synthesized ZnO–NPs.

Published: July 2020

Abstract
Recently, we introduced a novel measure of “average life span shortened” (ALSS) to improve comparability of premature mortality over time. In this study, we applied this novel measure to examine trends in premature mortality caused by hematological cancers in Canada from 1980 to 2015. Mortality data for Hodgkin lymphoma, non-Hodgkin lymphoma, multiple myeloma, and leukemia were obtained from the World Health Organization mortality database. Years of life lost was calculated according to Canadian life tables. ALSS was defined as the ratio between years of life lost and expected life span. Over the study period, age-standardized rates of mortality decreased for all types of hematological cancers. Our new ALSS measure showed favorable trends in premature mortality for all types of hematological cancers among both sexes. For instance, men with non-Hodgkin lymphoma lost an average of 23.7% of their life span in 1980 versus 16.1% in 2015, while women with non-Hodgkin lymphoma lost an average of 21.7% of their life span in 1980 versus 15.5% in 2015. Results from this study showed that patients with hematological cancers experienced prolonged survival over a 35-year period although the magnitude of these life span gains varied by types of hematological cancers.
Blood Pressure Variability and Dementia: A State-of-the-Art Review
Authors: Ma Yuan , Tully Phillip J , Hofman Albert , Tzourio Christophe 
Published: July 2020

Abstract
Accumulating evidence demonstrates that blood pressure variability (BPV) may contribute to target organ damage, causing coronary heart disease, stroke, and renal disease independent of the level of blood pressure (BP). Several lines of evidence have also linked increased BPV to a higher risk of cognitive decline and incident dementia. The estimated number of dementia cases worldwide is nearly 50 million, and this number continues to grow with increasing life expectancy. Because there is no effective treatment to modify the course of dementia, targeting modifiable vascular factors continues as a top priority for dementia prevention. A clear understanding of the role of BPV in dementia may shed light on the etiology, early prevention, and novel therapeutic targets of dementia, and has therefore gained substantial attention from researchers and clinicians. This review summarizes state-of-art evidence on the relationship between BPV and dementia, with a specific focus on the epidemiological evidence, the underlying mechanisms, and potential intervention strategies. We also discuss challenges and opportunities for future research to facilitate optimal BP management and the clinical translation of BPV for the risk assessment and prevention of dementia.
