Active arc suppression device based on voltage‐source convertor with consideration of line impedance in distribution networks

Published: November 2021

AbstractIn the non‐effectively grounding distribution system, residual current under single‐line‐to‐ground (SLG) fault threatens the safety of human being and power supply equipment. Active arc suppression device has been proved to be effective for SLG fault arc suppression when the line impedance is ignored. However, in practice, line impedance varies with the fault location and the load current flowing through the impedance brings about additional voltage drop, which increases the fault current and is not dealt with by the conventional methods. To achieve accurate SLG fault arc suppression with the existence of line impedance, the neutral‐to‐ground voltage reference for full ground‐fault current compensation is firstly derived and a detection method is then proposed. The pre‐fault and post‐fault line currents are used to eliminate the influence of load current on the line impedance voltage drop. A dual‐loop voltage and current controller is then designed. The prototype of active arc suppression device was developed. The results of simulation and prototype experiment validate the effectiveness of the proposed method.
Sensitivity of back‐projection algorithm (BPA) synthetic aperture radar (SAR) image formation to initial position, velocity, and attitude navigation errors
Authors: Lindstrom Colton , Christensen Randall , Gunther Jacob , Jenkins Scott 
Published: November 2021

AbstractThe Back‐Projection Algorithm (BPA) is a time‐domain‐matched filtering technique to form synthetic aperture radar (SAR) images. To produce high‐quality BPA images, precise navigation data for the radar platform must be known. Errors in position, velocity, or attitude result in improperly formed images that are corrupted by shifting and blurring. The contribution of this paper is the development of analytical expressions that characterise the relationship between navigation errors and image formation errors from an inertial navigation point of view, where trajectory estimation errors in position, velocity, and attitude propagate through time and cause compounding errors in the vehicle state vector. These analytical expressions are verified via simulated image formation and real‐data image formation.
Orthopaedic cardiac considerations in emergency
Authors: Katsanos Spyridon , Saranteas Theodosis , Mavrogenis Andreas F. 
Published: November 2021

Orthopaedic patients undergoing emergency orthopaedic surgery should be referred for cardiac evaluation only when they are symptomatic or when a specific cardiac intervention is expected to reduce the surgical risk. A preoperative delay of 24–48 h of emergency orthopaedic operations has been associated with increased mortality and poor functional status of the patients. Research in the preoperative setting is almost exclusively retrospective because randomized studies are difficult to be performed and pose serious ethical concerns. Moreover, inevitably, guidelines have a low level of evidence and do not always provide a straightforward framework for the preoperative care of the patients. This editorial revisits the most common clinical cardiology dilemmas for emergency orthopaedic surgery to explore controversies of current recommendations and elaborate on the role of echocardiography in the perioperative period in emergency orthopaedic surgery.

Significance
Synapses connecting granule cells to Purkinje neurons are considered essential sites for learning in the cerebellum. Strikingly, most of them appear to be silent: they do not transmit any electrical information. This may relate to information storage capacity and reliability, which are expected to improve during postnatal maturation. Here, we quantify the proportion of silent synapses in mice by combining optogenetic mapping of synaptic inputs and Purkinje neuron patch-clamp recording. We show that this proportion remains stable between the stage immediately following the postnatal establishment of cerebellar circuitry and 3 wk later when cerebellar function has maturated, presumably as a result of natural learning processes. Our results suggest that information storage capacity and reliability are optimized early during cerebellar maturation.
Variation in mild context-sensitivity
Authors: Frank Robert , Hunter Tim 
Published: November 2021

Abstract
Aravind Joshi famously hypothesized that natural language syntax was characterized (in part) by mildly
context-sensitive generative power. Subsequent work in mathematical linguistics over the past three decades has revealed
surprising convergences among a wide variety of grammatical formalisms, all of which can be said to be mildly context-sensitive.
But this convergence is not absolute. Not all mildly context-sensitive formalisms can generate exactly the same stringsets (i.e.
they are not all weakly equivalent), and even when two formalisms can both generate a certain stringset, there might be
differences in the structural descriptions they use to do so. It has generally been difficult to find cases where such differences
in structural descriptions can be pinpointed in a way that allows linguistic considerations to be brought to bear on choices
between formalisms, but in this paper we present one such case. The empirical pattern of interest involves wh-movement
dependencies in languages that do not enforce the wh-island constraint. This pattern draws attention to two related dimensions of
variation among formalisms: whether structures grow monotonically from one end to another, and whether structure-building
operations are conditioned by only a finite amount of derivational state. From this perspective, we show that one class of
formalisms generates the crucial empirical pattern using structures that align with mainstream syntactic analysis, and another
class can only generate that same string pattern in a linguistically unnatural way. This is particularly interesting given that
(i) the structurally-inadequate formalisms are strictly more powerful than the structurally-adequate ones from the perspective of
weak generative capacity, and (ii) the formalism based on derivational operations that appear on the surface to align most closely
with the mechanisms adopted in contemporary work in syntactic theory (merge and move) are the formalisms that fail to align with
the analyses proposed in that work when the phenomenon is considered in full generality.
Material and embodied resources in the accomplishment of closings in technology-mediated business meetings
Authors: Oittinen Tuire 
Published: November 2021

AbstractThis study uses conversation analysis (CA) and video-recorded data from an international company to investigate closings in technology-mediated (i.e. distant) meetings. The focus is on the situated affordances and multimodal resources that the chair and participants deploy to transition from meeting talk to a coordinated exit. Due to restricted access to bodily-visual leave-taking behaviours, other mutually recognized practices need to be implemented to initiate and advance closings: (1) when closing is made relevant as the next step, (2) when opportunity spaces to move out of the closing emerge, and (3) when departure from the meeting needs to be negotiated. This progression requires the close coordination of co-participants’ vocal and embodied conduct in the physical setting and rendering actions publicly intelligible via the screen at specific moments. The analysis portrays closings as emergent, collaborative accomplishments, in which the import of multimodal turn constructions and (dis)aligning behaviours must be negotiatedin situ.

Published: November 2021

Abstract
Conductive hydrogels are soft materials which have been used by some researchers as resistive strain sensors in the last years. The electrical resistance change, when the sensor is stretched or compressed, is usually measured by the two-electrode method. This method is not always suitable to measure the electrical resistance of polymers-based materials, like hydrogels, because it could be highly influenced by the electrode/sample interface, as explained in this study. For this reason, a signal conditioning circuit, based on four-electrode impedance measurements, is proposed to measure the electrical resistance change when the gel is stretched or compressed. Experimental results show that the tested gels can be used as resistance force/pressure sensors with a quite linear behaviour.

Published: November 2021

Abstract
Recent views on the use of preservatives sorbic and benzoic acids and their salts in meat products are presented from the point of accordance with current legislation in the Republic of Serbia and the EU, food safety and public health risks, and mainstreams in the methodology for their determination. These preservatives are permitted to be added individually or in combination, the maximum level is applicable to the sum and the levels are expressed as the free acid. Currently set values of the recommended daily intake of sorbate and benzoate are 25 mg/kg and 5 mg/kg, respectively. These values vary and depend on regulations in different countries. Considering control of the use of these additives, the most common methods for their determination are chromatographic methods based on high performance, or high pressure, liquid chromatography with diode array detectors.

Abstract
Since 2020, the rapid spread of the SARS-CoV-2 virus has caused the global pandemic COVID-19, generating health, economic and social impacts. The rapid spread of the infection in the human population required an accelerated adaptation to the new circumstances to protect human health and mitigate financial losses. As the ongoing pandemic has caused reported cases in the multi-millions, all stakeholders need to prevent further outbreaks and mitigate associated risks. Hence, besides government, health care systems, business stakeholders, public authorities, non-governmental organizations, and other socially responsible associations, the food sector has a crucial role in combating COVID-19. The food sector in this context is referred to as every actor in the food supply chain. This paper explores the difficulties in the entire food supply chain’s reactions to the pandemic crisis and underlines the meat sector’s response.

Published: November 2021

Abstract
The increasing use of genetically modified (GM) foods and feeds attracts the interest of media and public, causing great concern among consumers about the consequences of their consumption. The issues of concern are mainly focused on the impact on consumer health and the repercussions on the environment. The biggest fears are the possible negative consequences on human and animal health, which encompass allergic reactions, side effects such as toxicity, damage to individual organs, gene transfer and differences in nutritional value. Consumers are unsure and confused as to whether consuming GM foods is harmful to their health or not. According to a Pew Research Center survey conducted between October 2019 and March 2020, 48% of respondents said GM foods are harmful, 13% responded GM foods are safe, while 37% of respondents could not express their opinion due to lack of knowledge about it. Numerous studies have been undertaken to examine the effects that GM foods and feeds exert on humans and animals. The results differ in many ways that issue numerous questions. In this paper, we will try addressing questions that concern the public, as well as the activities and measures that science and competent institutions are taking to confront them.
Evaluation of trace element levels in beef cuts available to the consumers in Serbia
Authors: Djinovic-Stojanovic J , Jankovic S , Nikolic D , Vranic D 
Published: November 2021

Abstract
The present study evaluated the levels of Mn, Se, Cu and Zn in beef cuts available at markets in Serbia. We also assessed the risk associated with the consumption of these foods based on the estimated daily intake (EDI) of these elements. Thirty-six beef meat cuts were analysed using inductively coupled plasma mass spectrometry (ICP-MS). The EDI of all the studied elements was estimated on the basis of a calculation of the amount of beef consumed by Serbian households (mean beef consumption of 17.2 g/person/day). The studied beef cuts pose no risk with respect to the EDIs of Mn, Se, Cu and Zn. Among the four studied beef cuts, shoulder had the highest content of dietary zinc (68.2 mg/kg).

Current view on the assessment of antioxidant and antiradical activities: A mini review
Authors: Kupaeva N V , Kotenkova E A 
Published: November 2021

Abstract
The main problems in assessing the antioxidant properties of plant biologically active compounds are discussed in this review. Antioxidant potential should be considered as a combination of antioxidant and antiradical activities, since antiradical activity is part of the antioxidant activity and does not always coincide with antioxidant activity. The mechanisms of action and the existing experimental and computational methods for their evaluation were reviewed. Methods like FRAP, CUPRAC etc. could be used for assessment of antioxidant activity of plant compounds, but it is necessary to perform studies on cell cultures or laboratory animals in order to determine mechanisms of action on the antioxidant system of a living organism. The current methodological approaches for studying antiradical activity and its mechanisms include experimental methods such as DPPH, ABTS and ORAC, and computational methods based on density functional theory. The main thermodynamic parameters for evaluating antiradical mechanisms (HAT, SET-PT and SPLET) are the bond dissociation enthalpy, ionization potential, proton dissociation enthalpy, proton affinity, and electron transfer enthalpy, among others. The existing approaches for determining the antiradical mechanisms of antioxidants are quite informative, but can still cannot predict or determine by in vitro methods the antioxidant mechanism of these compounds in organisms consisting of many complex individual systems.

Published: November 2021

Abstract
The goal of this paper was to examine the slaughter characteristics of meat from Hybro G+ provenance broilers. Characteristics studied were dressing percentage, breast, leg (thigh and drumstick) and abdominal fat in chilled carcass, and percentage of meat, bones and skin in breast and leg. In this trial, one-day broilers of Hybro G+ provenance were raised under the same zoohygienic and ambient conditions that met the technological requirements for this provenance and were provided with feed and water ad libitum. After 42 days’ fattening, broilers were slaughtered and the resultant carcasses were air chilled. The average dressing percentage was 73.15%, and in carcasses, the average percentage of breast was 34.33%, leg was 27.91% and abdominal fat was 1.13%. The percentage in breast and leg of meat was 72.61% and 70.38%, of skin was 8.00% and 9.45% and of bones was 19.79% and 19.59%, respectively. The meat:bone ratio was 0.27 for breast and 0.28 for leg.
The nutritional and health value of beef lipids - fatty acid composition in grass-fed and grain-fed beef
Authors: Lukic M , Trbovic D , Karan D , Petrovic Z , Jovanovic J , Babic Milijasevic J , Nikolic A 
Published: November 2021

Abstract
Interest in meat fatty acid (FA) composition stems mainly from the need to find ways to produce healthier meat with a suitable ratio of polyunsaturated (PUFA) to saturated fatty acids (SFA) and a favourable balance between n-6 and n-3 PUFA. Studies of grass feeding versus grain feeding cattle have been conducted in different regions throughout the world and suggest that grass-based diets can significantly improve the fatty acid (FA) composition of beef. Compared with grain diets, grass diets contribute to a lower total fat content and more favourable SFA composition i.e. higher proportion of low density lipoprotein (LDL) and cholesterol-neutral stearic acid (C18:0). Feeding fresh grass compared to concentrates results in higher levels of n-3 PUFA in muscle lipids and a more favourable n-6/n-3 PUFA ratio that is within the nutritional recommendations for the human diet.

Abstract
Sturgeon fish species are food fish of commercial significance in many countries. Sturgeon farming in Serbia is a relatively new branch of aquaculture, and sturgeon farming has been developing in the last several years. The objective of this study was to examine morpho-physiological and slaughter characteristics and proximate composition of one-year-old sturgeons produced in a recirculating aquaculture system (RAS). Sturgeons were cultured in a RAS system nearby Novi Sad and were fed with commercial feed. Moisture content in fillets ranged from 75.63 to 77.91%, protein content from 18.06 to 18.89% and lipid content from 2.37 to 4.38%. The slaughter performance results are in agreement with those reported by various authors for different strains of sturgeons. Sturgeon species have potential to become an attractive fish in our aquaculture in terms of overall proximate composition and slaughter performance.

Abstract
The aim of this study was to investigate antibacterial effects of oregano and thyme essential oils on Listeria monocytogenes in fermented sausages and their effect on the sensory characteristics of these sausages. For testing purposes, sausages contaminated with L. monocytogenes were produced. Changes in the microbiological status of fermented sausages and physicochemical properties were monitored during ripening. Essential oils exhibited antibacterial activity against L. monocytogenes, and in the groups with a high concentration (0.6%) of oregano or thyme essential oils (KLO2 and KLT2), the number of L. monocytogenes was below the detection threshold on day 14 of ripening, with a stronger effect of oregano. In groups with 0.3% essential oil of oregano or thyme added, the number of L. monocytogenes was reduced to below the detection threshold on day 21 of ripening. During the ripening, the aw and pH of all test groups of fermented sausages decreased. Experimental sausages with 0.3% thyme essential oil had acceptable smell and taste, while in other experimental groups, sausage smell and taste were very intense, uncharacteristic and unacceptable.

Abstract
This research presents the results of a comparison assessment of the cholesterol content, fatty acid profile, and atherogenic (IA) and thrombogenic (IT) health lipid parameters of four dry fermented sausages produced from Mangalitsa and Swedish Landrace pork meat. The highest cholesterol level was found in Sremska sausage prepared from Landrace meat (64.92 mg/100g). Polyunsaturated fatty acid (PUFA) levels were considerably greater in Landrace meat sausages than in other kinds. The main cause of these variations was a higher overall n-6 PUFA concentration. The sausages made from Mangalitsa meat had the highest levels of monounsaturated fatty acid (MUFA) and unsaturated fatty acid (USFA). The highest saturated fatty acid (SFA) level was found in sausages prepared from Landrace meat. Fermented sausages made from Mangalitsa pork meat show better health lipid indices, atherogenic (IA), thrombogenic (IT), and PUFA/SFA ratios.

Abstract
In monogastric animals, tissue fatty acid profile directly reflects the fatty acid profile present in the animal’s diet. Inadequate ratio of fatty acids in food can lead to negative effects on human health. Conjugated linoleic acid (CLA) is a group of isomers of linoleic acid (C18:2), and its most interesting role is in the prevention of tumors, atherosclerosis and diabetes. CLA is found in ruminant meat and milk, and since pigs and poultry do not have the ability to synthesize CLA, it is possible to add them to animal feed with biotechnological solutions. The scientific public imposes modern parameters for determining the nutritional value of fatty acids, in which the AI – index of atherogenicity, TI – index of thrombogenicity and H/H - hypocholesterolemic/hypercholesterolemic ratio are distinguished. The aim of this study was to determine the effect CLA addition to the diet of non-ruminants on the lipid indices of certain categories of meat, from the aspect of consumer health needs. A significant influence of the correction of feed’s fatty acid composition on the lipid indices in food of animal origin was determined.
