Inconsistent reporting of life experiences: What people think and how they explain it?
Authors: Azevedo Vanessa , Martins Carla , Carvalho Margarida , Maia Ângela
Published: November 2021

Assessment of life experiences relies mainly on cross-sectional retrospective design, despite the concerns regarding inconsistent reports. Studies suggest that some individuals change their answers when asked repeatedly, but common opinions underlying this behaviour remain unknown. Our study explored personal perceptions regarding inconsistent reporting and identified associated reasons including individual, experiences-related, and design-related characteristics. Seventy-two individuals, enrolled in a longitudinal study about life experiences, answered a measure about general perceptions and involved reasons. Participants seemed to be aware that inconsistent reporting is a common behaviour, which highly impact on research. A cluster analysis revealed two clusters (i.e., variables involved versus not involved). Most disagreed that sociodemographic variables influence inconsistency, whereas memory, mood, valence, impact, mode of data collection, and interviewer features were pointed as key-variables. Our results suggest that inconsistent reporting is not straightforward and it is probably rooted in a varied and complex set of variables.
El cerebro y la conciencia: una propuesta integradora entre Damásio y Zubiri
Authors: Jácomo António , Sanmartín Catalán Carlos
Published: November 2021

El estudio del sistema nervioso y sus funciones es fascinante y complejo. Uno de los asuntos más intrigantes de este campo es cómo la neurobiología produce estados conscientes. Para el estudio del complejo problema de la conciencia, son necesarios conocimientos tanto de neuroanatomía y fisiología como de lingüística y filosofía, lo que lo convierte en un problema temido o sencillamente ignorado tanto por científicos como por filósofos. Pero este desprecio del problema, lejos de resolverlo, desemboca en una reflexión reduccionista, que trata de ver un dilema donde hay un problema. En este artículo pretendemos aproximar las neurociencias y la filosofía, en el sentido de comprender cuál es la contribución que cada una puede ofrecer y, al mismo tiempo, sistematizar el conocimiento que de esta relación podemos extraer. Para ello, nos centraremos en las reflexiones del neurocientífico Damásio, especialmente de su concepto de conciencia ampliada, pero también en la teoría filosófica de Zubiri, y sus conceptos de biografía, «inteligencia sentiente» e «intimidad».

Published: November 2021

Phytoplankton plays an important role in marine ecosystems as  primary producer, as the basis of food chains and the food web, and are widely used as bioindicators to monitor water condition. The study of phytoplankton is the primary interest to explore aquatic resources for blue biotechnology applications in conditions as a live feed, antibacterial, antiviral, antioxidant, pharmaceutical, cosmetics, possibly food and health industry. The study aims to assess the composition, abundance and diversity of phytoplankton community in Lemukutan Island waters of West Kalimantan. The present study found 31 genera of phytoplankton, consisted of Bacillariophyceae (28 genera) and Dinophyceae (3 genera). In term of contribution, Bacillariophyceae were found to be dominant (93.035%) than dinophyceae (6.965%). The abundance of phytoplankton varied between 636.91 to 2034.48 cell.L-1. The diversity index (H’), the evenness (E) index, and the dominance (C) index ranged from 1.959–2.579, 0.582–0.868, 0.094–0.283, respectively. The result showed that the diversity index was moderate, the evenness index was high, and the dominance index was low.

Authors: Sellapillaibanumathi Latha , Dhanarajan Arulbalachandran , Raina Aamir , Ganesan Aswini
Published: November 2021

The present study was carried out to analyse the effect of gamma radiation on morpho-physiological parameters of seven days old M1 seedlings of Eleusine coracana (L.) Gaertn. (finger millet). The finger millet seeds were irradiated with different doses of viz., 100 Gy, 200 Gy, 300 Gy, 400 Gy, 500 Gy, 600 Gy, 700 Gy, 800 Gy, 900 Gy and 1000 Gy of gamma ray. Higher doses of gamma rays induced substantial reduction in mean performance of morphological and physiological traits. However, lower doses showed stimulatory effects on morphological and physiological traits. The results revealed a progressive decrease in chlorophyll fluorescence with increasing dose of gamma irradiation. Among all the mutagen doses used, 600 Gy gamma irradiated seeds showed enhanced mean performance of morphological and physiological traits in finger millet. Hence 600 Gy gamma rays may be employed in other crop species to improve the agro-economic traits

Published: November 2021

Micropropagation is currently the most commercially effective plant biotechnology that helps in the rapid generation of a large number of clonal plants of many plant species in a short period. Effective protocol was developed for in vitro micropropagation of Solanum lycopersicum (tomato) using chemical-free organic vermicompost (VC) extract medium. This experiment aims to expose the advancement in plant tissue culture technique by using synthetic Murashige and Skoog medium (MS) medium and a chemical-free organic VC (30%) extract along with 4% coelomic fluid (obtained from the earthworms Eudrilus eugeniae) as a growth medium for in vitro studies. The response of roots, leaves, shoots, and nodes in both synthetic (MS) medium and chemical-free organic VC extract medium was compared statistically using Student’s t-test. Statistically significant differences for the number of roots (P =0.011), leaves (P=0.012), and nodes (P=0.001) between the two media were reported. Both media showed the same shoot induction where no significant differences were reported with a P value of 1.000 for shoots. The protocol has led to a 100% plant survival rate on chemical-free organic vermicompost extract media. The results have also shown a significant difference in growth rate between two different media. Vermicompost and coelomic fluid used in media have antimicrobial activities which led to minimal contamination level and this consequently minimized timely subculturing. Through our studies, we found that chemical-free organic vermicompost extract media proved to be more economical and a better prospective than MS media for in vitro propagation of tomato.

Combined BNCT and PET for theranostics
Authors: Silarski Michał , Dziedzic-Kocurek Katarzyna , Szczepanek Monika
Published: November 2021

This short review summarizes the issue of boron distribution monitoring in boron neutron capture therapy (BNCT), which remains a serious drawback of this powerful oncological treatment. Here we present the monitoring methods that are presently used with particular emphasis on the positron emission tomography (PET) which has the highest potential to be used for the real-time monitoring of boron biodistribution. We discuss the possibility of using present PET scanners to determine the boron uptake in vivo before the BNCT treatment with the use of p-boronphenylalanine (BPA) labeled with 18F isotope. Several examples of preclinical studies and clinical trials performed with the use of [18F]FBPA are shown. We also discuss shortly the perspectives of using other radiotracers and boron carriers which may significantly improve the boron imaging with the use of the state-of-the-art Total-Body PET scanners providing a theranostic approach in the BNCT.

Modular iterated integrals associated with cusp forms
Authors: Diamantis Nikolaos
Published: November 2021

We construct an explicit family of modular iterated integrals which involves cusp forms. This leads to a new method of producing modular invariant functions based on iterated integrals of modular forms. The construction will be based on an extension of higher-order modular forms which, in contrast to the standard higher-order forms, applies to general Fuchsian groups of the first kind and, as such, is of independent interest.

Invisibility concentrator based on van der Waals semiconductor α-MoO3
Authors: Hou Tao , Tao Sicen , Mu Haoran , Bao Qiaoliang , Chen Huanyang
Published: November 2021

By combining transformation optics and van der Waals layered materials, an invisibility concentrator with a thin layer of α-MoO3 wrapping around a cylinder is proposed. It inherits the effects of invisibility and energy concentration at Fabry–Pérot resonance frequencies, with tiny scattering. Due to the natural in-plane hyperbolicity in α-MoO3, the challenges of experimental complexity and infinite dielectric constant can be resolved perfectly. Through analytical calculation and numerical simulations, the relevant functionalities including invisibility, energy concentration and illusion effect of the designed device are confirmed, which provides guidelines for the subsequent experimental verification in future.
From Drawing into Digital: On the Transformation of Knowledge Production in Postexcavation Processing
Authors: Rösch Felix
Published: November 2021

Digital methods have undoubtedly become an integral part of archaeology in recent decades. This has had a major impact on how archaeological knowledge is produced. Accordingly, there has been a recent increase in the number of studies addressing this issue and calling for a reflexive approach. Although studies have so far focused on the changes in knowledge production in fieldwork practices, studies of postexcavation processes are rare. This way of archaeological knowledge production is described using the analysis of old excavation documentation of the medieval waterfront of Schleswig, northern Germany, through geographic information system. It is achieved by an approach that combines the methodological tool of achaîne opératoirewith concepts based on the actor-network theory, whereby the production of knowledge is understood as a translation network. The approach reveals the individual processing steps and how the data change. Accordingly, for each step, not only are the applied practices described in detail, but also the influence of actors, devices, and documents is mentioned. This allows not only a critical reflection of the approach and a review of the interpretation, but also demonstrates that profound archaeological findings are possible despite data alteration through digital methods.

Die Prognose der Diabeteserkrankung wird entscheidend vom Selbstbehandlungsverhalten der Betroffenen beeinflusst. Psychosoziale Aspekte wie krankheitsspezifische Belastungen, subklinische oder klinische psychische Störungen stellen eine wesentliche Barriere für eine erfolgreiche Diabetestherapie dar. Deshalb ist ein Screening auf mögliche psychische Belastungen sinnvoll. Beim Auftreten psychischer Komorbiditäten ist eine Mitbehandlung durch diabeteserfahrene psychologische oder ärztliche Psychotherapeuten sinnvoll.

Logwood Writing Inks: History, Production, Forensics, and Use
Authors: Neevel Han
Published: November 2021

In the 16th century, the Spanish brought logwood from Mexico to Europe. Its extract was used for textile dyeing. The French introduced the logwood tree to Western Hispaniola, which became Haiti in 1804. Around 1880, Haiti exported most of its logwood to France. In 1847, Runge introduced the black chrome-logwood ink as an alternative for iron-gall ink, because the latter attacked the steel writing nibs. The most important constituents of logwood are hematoxylin and hematein. Due to the profitable import conditions from Haiti, chrome-logwood ink became the cheapest and most commonly used black writing ink in France. This could explain why Vincent van Gogh, during his French period, used it for writing and drawing and why most of the French postcards from the first half of the 20th century, studied in this publication, were written with chrome-logwood ink, while most of the Dutch postcards were written with an iron gall ink.

Published: November 2021

Objectives

Cryptotanshinone (CPT), a natural quinoid diterpene, isolated from Salvia miltiorrhiza, has shown various pharmacological properties. However, its effect on chronic unpredictable stress (CUS)-induced depression phenotypes and the underlying mechanism remain unclear. Therefore, the aim of this study was to investigate whether CPT could exert an antidepressant effect.

Methods

We investigated the effects of CPT in a CUS-induced depression model and explored whether these effects were related to the anti-inflammatory and neurogenesis promoting properties by investigating the expression levels of various signaling molecules at the mRNA and protein levels.

Results

Administration of CPT improved depression-like behaviors in CUS-induced mice. CPT administration increased the levels of doublecortin-positive cells and reversed the decrease in the expression levels of brain-derived neurotrophic factor (BDNF)/tyrosine kinase receptor B (TrkB) signaling transduction, as well as the downstream functional proteins, phosphorylated extracellular regulated protein kinases (p-ERK), and cyclic adenosine monophosphate (cAMP)-response element-binding protein levels (p-CREB) in hippocampus. CPT treatment also inhibited the activation of microglia and suppressed M1 microglial polarization, while promoting M2 microglial polarization by monitoring the expression levels of arginase 1 (Arg-1) and inducible nitric oxide synthase (iNOS), and further inhibited the expression of proinflammatory cytokines, including interleukin (IL)-1, IL-6, and tumor necrosis factor-α (TNF-α), and increased the expression of the anti-inflammatory cytokine IL-10 by regulating nuclear factor-κB (NF-κB) activation.

Conclusions

CPT relieves the depressive-like state in CUS-induced mice by enhancing neurogenesis and inhibiting inflammation through the BDNF/TrkB and NF-κB pathways and could therefore serve as a promising candidate for the treatment of depression.
Synthesis and coordination to the coinage metals of a trimethylpyrazolyl substituted 3-arylacetylacetone
Authors: van Terwingen Steven , Nachtigall Noah , Englert Ulli
Published: November 2021

The ligand 3-(4-(1,3,5-trimethyl-1H-pyrazol-4-yl)phenyl)acetylacetone (1) combines a Pearson hard O,O′ chelating acetylacetone donor with a softer pyrazole N donor bridged by a phenylene spacer. Deprotonation and coordination to CuIIleads to a square planar bis-acetylacetonato complex; interpreting the close proximity of an adjacent complex’s pyrazole moiety as anη2${{\eta}}^{2}$coordination to the axial CuIIposition leads to a two dimensional extended structure. The N donor capabilities are proven by coordination to AgPF6and AuCl; for AgIa cationic linear bis-pyrazole complex as a toluene solvate is obtained with toluene-pyrazole π-interactions and an essentially uncoordinatedPF6-${{\mathrm{PF}}_{6}}^{-}$anion. In the case of AuCl a neutral linear coordination compound with one chlorido and one pyrazole ligand1is obtained. Comparing the dihedral angles with a closely related but shorter ligand reveals a larger rotational degree of freedom in1, allowing for richer architectures in emerging coordination polymers.
Properties at Low Temperatures of Asphalt Mixes Containing High Content of Multi-recycled RAP
Authors: Pedraza Alvaro , Di Benedetto Herve , Sauzéat Cédric , Pouget Simon
Published: November 2021

The reuse of reclaimed asphalt pavement (RAP) in the production of new asphalt mixes is a valuable environmental approach. Likewise, new lower-temperature manufacturing processes (warm) of asphalt mixes have an impact in the reduced fuel consumption and gas emissions during production. In 2014, the French National Research Agency launched the French national project “Innovation for Materials and Processes for Improving the Multi-Recycling of Mixtures” (IMPROVMURE). The main objective of the IMPROVMURE project was to determine, over the life cycle of pavement materials, the impact of successive recycling at different rates and for different manufacturing techniques (hot and warm processes). To estimate the thermomechanical properties of multi-recycled asphalt mixes, a characterization of behavior by coupling the thermal and mechanical effects at low temperatures was carried out. This paper presents the thermal stress restrained specimen test (TSRST) results of six asphalt mix types, three hot asphalt mixes, and three half-warm asphalt mixes using a foamed binder. Some of these asphalt mixes were manufactured with a content up to 70 % RAP and 70 % multi-recycled RAP. TSRST were performed on cylindrical specimens at the University of Lyon/école nationale des travaux publics de l’état (ENTPE). The failure temperature (TF), failure stress (σF), and failure radial deformation (εrF) were evaluated to analyze and compare the behavior of mixes at low temperature. The influences of RAP content, recycling cycle, air void content, and manufacturing process were studied, and the air void content showed an effect inversely proportional to the failure stress.
Sustainability Analysis of Machining Inconel 718 Using Graphene-Based Nanofluids and Self-Lubricating Tools
Authors: Amrita M. , Revuru Rukmini Srikant , Siva B. , Kamesh B.
Published: November 2021

Inconel 718 has wide application due to its excellent strength at high temperatures and corrosion resistance. But because of the problems associated with machining, it is categorized as "hard-to-machine" material. The present work aims at identifying a sustainable method to machine Inconel 718 with the application of graphene. Sustainability evaluation consists of evaluating a product or process for the satisfaction of three E’s: employee, environment, and economy. In the present work, the effect of graphene-based cutting fluid and graphene-based self-lubricating tools on cutting forces and tool wear is evaluated while machining Inconel 718. In addition, economic analysis and carbon footprint analysis are carried out to verify the advantage and feasibility of using the formulated cutting fluids and self-lubricating tools. Furthermore, minimum quantity application of conventional cutting fluid and graphene-based nanofluids and dry machining using graphene-based self-lubricating tools are compared to estimate the best conditions for environmental impact. Minimum quantity application of 0.5 weight percent (wt %) graphene-based nanofluid showed the least tangential cutting forces, while 0.3 wt % showed the least tool wear. Tool wear decreased by ≈70–84 % with 0.3 wt % graphene-based nanofluid compared with dry machining over the velocity range of 65–115 m/min. At 112 m/min, the minimum quantity application of 0.3 wt % graphene-based nanofluid reduced carbon emission by 3,334 kg carbon dioxide compared with dry machining per machine tool per year. Minimum quantity application of 0.3 wt % graphene-based nanofluid is also found to be most economical compared with other environments at all cutting velocities showing ≈70–80 % reduction in expenditure compared with dry machining.
The Political Economy of Autocratization
Authors: Trantidis Aris
Published: November 2021

In competitive authoritarian systems, aspiring autocrats must win elections and marginalize the political opposition. In Belarus, President Alexander Lukashenko’s strategy for political hegemony heavily relied on socioeconomic co-optation, offering privileges to supporters and imposing sanctions on dissenters. In an economy dominated by the state, co-optation had a coercive effect on behavior. Without sizable areas of activity autonomous from the government, citizens could not defy or mitigate the cost of reprisals for openly supporting the political opposition. Through co-optation, Lukashenko weakened the opposition and built an authoritarian regime without resorting to extensive political violence, which could have undermined his claim of public legitimacy.
Coronavirus Pandemic Response and Voter Choice
Authors: Glaurdić Josip , Lesschaeve Christophe , Mochtak Michal
Published: November 2021

Does the public perception of governments’ coronavirus pandemic responses actually make a difference to their electoral fortunes? In this research note, we answer that question by presenting the preliminary results of a survey of more than 3,000 voters in Croatia and Serbia conducted on a dedicated mobile app and web platform directly preceding parliamentary elections that took place in these two countries during the summer of 2020. This survey was part of our larger project tracking political competition, public discourse, and conspiracy theories in Southeast Europe during the coronavirus pandemic. The preliminary findings presented in this research note demonstrate Croatian and Serbian voters were rationally retrospective and rewarded parties in power based on evaluations of their crisis management performance. We also find evidence of voters who have personally witnessed the health consequences of the coronavirus being more likely to support the parties in power. We believe this is evidence of the coronavirus pandemic increasing affected citizens’ expectations of and trust in national governments where those governments respond strongly to the pandemic’s first wave, as was the case in both Croatia and Serbia.

Authors: Uralbekov Bolat , Satybaldiyev Bagdat , Snow Daniel
Published: November 2021

The water of the Syr Darya is the main source of fresh water in South Kazakhstan and heavily used for agriculture. The use water from the Syr Darya for irrigation of agricultural fields affects its chemical composition and is reflected in the water quality class provided in the bulletins of the Ministry of Ecology, Geology and Natural Resources of the Republic of Kazakhstan. In the present work, the distribution of suspended and dissolved forms of heavy metals in the water of the Syr Darya has been studied in two areas – the upper reaches of the river from the Shardara reservoir to the «Koksaray» bridge and the lower reaches of the river from Turkestan to Terenozek. Concentrations of heavy metals and metalloids were determined by inductively coupled plasma mass spectrometry (ICP-MS, Agilent 7500A, United States) and compared to these recommended levels. Total concentrations of several metals (V, Cu, Mn, Fe, Sr) exceed the Maximum Permissible Concentrations established for waters of fishery reservoirs. The role of the suspended form in the geochemical migration of a number of metals in the water of the Syr Darya River is estimated and it was shown that this form is a significant fraction of the total metal concentration. The distribution of suspended forms of metals correlates to the turbidity of the water of the Syr Darya.
Desgarrar la Imagen. Prácticas de Indisciplina Visual en la Formación de Educadoras
Authors: Gutiérrez-Cabello Barragán Aingeru , Peña-Zabala Miriam , Guerra Guezuraga Regina
Published: November 2021

El presente trabajo reflexiona sobre el papel de la imagen de consumo durante la formación inicial de educadoras. Rescatamos los resultados de una serie de prácticas de creación visual desarrolladas por el alumnado, y elaboradas a partir de la representación de lo corpóreo en contextos de comunicación publicitaria. Analizamos estas producciones desde el marco teórico de los nuevos materialismos, llevando a cabo una lectura difractiva de sus producciones visuales. Nos valemos de conceptos como el de “desgarro” para leer y seguir ampliando los sentidos sobre la subjetividad de las futuras educadoras, cuestionando el contexto, lo conceptual y la hiperrealidad de la imagen de consumo. Se muestran resultados de producciones visuales que dialogan con dichas imágenes, potenciando así la agencia de las futuras educadoras como productoras de imaginarios críticos con los discursos publicitarios. Entendemos necesario continuar reflexionando durante la formación inicial sobre los regímenes políticos de lo visual, su influencia en la construcción de significados, así como en la propia tarea pedagógica. Favorecer espacios de pensamiento en torno a la imagen que permitan cuestionar aquellas producciones visuales vinculadas al cuerpo, alejándonos así de la posición de consumidores de cultura visual para pasar a convertirnos en productores que representan aquellas realidades aún sin imágenes.

A standard MTT-test performed on both MT-4 and Namalva cell lines was used to assess cytotoxic effects. Results. Based on electrophoresis data, it was found that despite chemical modifications of the natural casein, the medication based on it is characterized by a high ability to hydrolyze by digestive enzymes under the same conditions as casein. Also, an MTT-test demonstrates that the medication has no cytotoxic properties against cell lines MT-4 and Namalva. Conclusions. Since the negative effects of the drug associated with its digestibility and toxicity have not been observed, it is recommended to continue the study of its effects on living organisms.

Subject and Purpose. The progress in the development of communication means requires a brand-new radar-component base and state-of-the-art technologies of signal processing. Last years, passive radar systems have become increasingly important. Yet such a shortcoming as poor estimation of the target distance takes place when the signal reception is only provided by a single station. The present work suggests a concept of the object distance determination by passive radar means under far-tropospheric radio wave propagation upon that the statistical parameters of amplitude fluctuations of the target reflection beyond the radiohorizon are distance dependent. Methods and Methodology. The basic mechanism of radio wave propagation beyond the radiohorizon is a phenomenon of tropospheric scatter on tropospheric heterogeneities in the upper tropospheric layers. These heterogeneities continuously change form and size and move through the space. The resulting electromagnetic field at the reception point represents additively combined radio wave powers scattered by all heterogeneities in the illuminated area that varies its height depending on the distance so that the statistical parameters of received signal fluctuations are distance dependent. After statistical processing of received signal fluctuations, the target distance can be determined. The present work examines radiowave propagation of the 3 cm and 50 cm waves over the Sea of Okhotsk with target distances up to 500 km. Results. For the target distance estimation by passive radar means, the standard deviation value, s, of the received signal amplitude can be employed. Conclusion. The distance dependence of the statistical parameters of amplitude fluctuations of the target signal allows the target distance to be estimated by a passive radar in the centimeter, decimeter and meter wave ranges.

Published: November 2021

The polarization processes in Bi12SiO20 crystals doped with Fe (Bi12SiO20 : Fe) in the temperature interval 300–800 K are studied by the thermoactivation spectroscopy methods. The temperature dependences of the thermostimulated depolarization (TSD) currents and the dependences of the intensities of TSD current peaks on the polarization conditions are obtained. The mechanisms of space charge and quasidipole polarizations are revealed. The temperature dependences of the optical absorption of Bi12SiO20 : Fe crystals are also investigated.

The aim of this study was to evaluate the observers’ diagnostic performance in panoramic radiography using monitor, tablet, X-ray image view box, and against window daylight as a visualization method in different diagnostic tasks. Thirty panoramic radiography were assessed by three calibrated observers for each visualization method, in standardized light conditions, concerning dental caries, widened periodontal ligament space, and periapical bone defects from the four first molars; mucosal thickening and retention cysts in maxillary sinus; and stylo-hyoid ligament calcification and atheroma. A five-point confidence scale was used. The standard-reference was performed by two experienced observers. Diagnostic values using window light were significantly lower for caries and periapical bone defect and retention cyst, stylo-hyoid ligament calcification detection (p<0.05). For atheroma detection, X-ray image view box, tablet, and widow light had lower accuracy than the evaluation on the monitor (p<0.05). Observer’s diagnostic performances are worsened using window light as an evaluation method for panoramic radiography for dental, sinus, and calcification disorders, while the monitor was the most reliable method.

Using a bur multiple times to prepare dental structure may produce a smoother final surface on dentin than a new one. This superficial roughness may affect adhesion with resin-based materials by modifying the substrates’ characteristics. The aim of this study was to evaluate the effect of multiple uses of diamond burs on dentin’s superficial microroughness and bond strength with resin composite when using a self-etch adhesive. Diamond dental burs were used to simulate a preparation (dentin flat surface) on extracted third molars. Samples were distributed into groups according to burs’ number of previous uses as follows: 0, 1, 5 and 10. Scanning electron microscopy images at 70x, 350x, and 1000x were used to illustrate burs’ deformation. Each specimen’s dentin microroughness was measured three times to compare between experimental groups and the micro-shear bond strength test (n=15) was performed for the 0 and 10 uses groups using a universal adhesive in a self-etching mode. Diamond crystals wear and dislodgements were evident among groups where the burs were used more times. As the number of uses increased the mean microroughness of the dentin surface decreased with significant differences between the 0 and 10 uses groups. No statistical differences between experimental groups resulted from bond strength tests. When using a universal adhesive in a self-etching mode, the number of previous uses of a diamond bur seems to have no significant effect on dentin/resin composite bond strength.

Abstract. The article presents a three-year traceability (2018, 2019, 2020) of biometric results of the fruits of eight peach and nectarine varieties. The study covers the fifth, sixth and seventh vegetation period from the period of full fruiting. Varieties included in this investigation were “Filina” (peach, clingstone), “Gergana” (nectarine, clingstone), “July Lady” (peach, semi-clingstone), “Ufo 4” (flat peach, semi-clingstone), “Laskava” (peach, freestone), “Morsiani 90” (nectarine, freestone), “Flat Queen” (flat peach, freestone), and “Evmolpiya” (peach, freestone). The experimental collection plantation was created in the spring of 2014 on the territory of the Fruit Growing Research Institute, Plovdiv, (lat. 42.10384828045957 and long. 24.72164848814686). The data analysis shows that the varieties “Laskava” and “Evmolpiya” produce fruits with the highest weight – 319.60 g and 303.60 g, respectively. Medium weight is registered in the “Morsiani 90” variety (226.07 g) and the “July Lady” variety (193.87 g). “UFO 4” is characterized with the smallest fruits – an average of 143.83 g and the highest flesh yield. Considering the fact that the “Filina” variety is very early ripening, its fruits can be treated as large for the season – 170.21 g. The stones of the “July Lady”, “Morsiani 90” and “Evmolpiya” varieties have the largest average mass
Comparative study of a milking unit pulsation system in laboratory and field conditions
Authors: Dineva G.
Published: November 2021

Abstract. A comparative study of the pulsation phases in classic milking units was performed. The testing of the same is done in laboratory and field conditions (during milking). The pulsation settings at which the test was performed were pulsation rate 60 min-1 and 90 min-1, ratio 50/50% and vacuum mode 50 kPa. The experiments were performed in the laboratory of “Machine milking” (Department of Agricultural Engineering, Faculty of Agriculture, Trakia University) on a milking installation with a pipe line and on a farm for 60 lactating cows at the same milking installation. It was found that the transients (phases “a” and “c”) are significantly reduced during milking. Respectively, the actual phases (phases “b” and “d”) are significantly increased during the milking process. The conclusions are related to the settings and timely diagnostics of the milking machine.

Published: November 2021

The distribution of Dinochloa scandens is unclear. World bamboo checklists suggest it is relatively widespread in Malesia. Here we clarify issues with herbarium specimen identification. Besides, a synonym name of D. scandens, namely D. macrocarpa collected from the Philippines, needs to be reviewed. The study aims to provide information on distribution and to review the synonym of D. scandens. The habitat preferences of D. scandens are also presented. We carried out targeted fieldwork at Gunung Halimun-Salak National Park in West Java in 2019 and extensive examination of herbarium specimens from Herbarium Bogoriense and online portals to accurately circumscribe this species. All data were analyzed descriptively. Distribution, altitude, and rainfall maps for D. scandens were produced with ArcGIS Pro. Our examination on the specimens suggests that D. scandens is indeed endemic to West Java and Banten Provinces in Indonesia. This bamboo species can be found in lowland to mountain forests with an altitude of 20-1400 m, in areas with annual rainfall between 3000-4000 mm. We support D. macrocarpa as an accepted name for a bamboo species from the Philippines and remove it from synonymy with D. scandens due to clear differences in the fruit compared to specimens of D. scandens across its range.
