Authors: Alagöz Sedat
Published: February 2022

OBJECTIVE: In our study, the significance of preoperative whole blood and coagulation test values in predicting post-tonsillectomy bleeding were investigated. METHODS: The files of 115 pediatric patients who underwent bilateral tonsillectomy for chronic tonsillitis by the same surgical team between January 1, 2019, and December 31, 2020, in the ear, nose, and throat clinic of Adana City Training and Research Hospital were retrospectively reviewed. Patients with a history of coagulopathy and missing data were excluded from the study. The remaining 81 pediatric patients (34 females, 47 males; mean age 8.5±3 years; range, 3 to 17 years) were included in the study. All surgeons had at least five years of professional experience. RESULTS: After tonsillectomy, the patients were divided into two groups as those without (Group 1, n=53) and with (Group 2, n=28) bleeding in the operative field. Although the days of bleeding changed between the 1st and 14th days after surgery, it was most frequently observed on the 7th and 8th days. CONCLUSION: In our study, the age of the patient and the preoperative whole blood and coagulation parameters, hematocrit, neutrophil, and mean platelet volume, were found to be associated with bleeding after tonsillectomy.

Authors: Yükkaldıran Ahmet
Published: February 2022

OBJECTIVE: In this study, the hearing functions and inner ear conditions of beta (b)-thalassemia major patients who were treated with desferrioxamine were evaluated. METHODS: This study was conducted with 69 pediatric patients aged seven years and older (Thalassemia group; 42 males, 27 females; mean age 11.0±4.1 year; range, 7 to 15 year), diagnosed with b-thalassemia major, treated with regular iron-chelating agent desferrioxamine for at least three years, and followed in the pediatric hematology and oncology clinic and 67 children (Control group; 36 male, 31 female; mean 12.4±6.8 year; range, 5 to 17 year) without hearing loss and chronic ear disease between January 2017 and January 2020. The patient and control groups were examined by an otolaryngologist. Pure-tone audiometry and distortion product otoacoustic emission tests were performed on the patient and control groups, and the results were compared. RESULTS: No significant difference was found in terms of age and sex in the thalassemia and control groups. In the comparison of hearing thresholds between groups with pure-tone audiometry, the hearing thresholds of the thalassemia group were higher than the control group at a frequency of 8000 Hz in the right and left ears, and the difference was statistically significant. In the comparison of the signal-to-noise ratios between the groups with the distortion product otoacoustic emission test, the decibel values in the right ear at frequencies of 1000 Hz and 6000 Hz were lower in the thalassemia group than in the control group, and the difference was statistically significant. CONCLUSION: In the study, the inner ear functions were found to be affected in patients treated with desferrioxamine. Even if b-thalassemia major patients do not clinically describe hearing loss, we believe their hearing thresholds will increase starting from high frequencies with repetitive desferrioxamine treatment, and they may experience a hearing loss.

This study analyzes how knowledge-based network affects the dual innovation performance. Dual innovation includes exploratory and exploitative innovation, and knowledge-based network represents the relationships among knowledge-based elements. We take 269 enterprises having gone public in Shanghai and Shenzhen stock markets of the electronic information industry of China as samples and get the patent data for 5 years from 2014 to 2018. We consider building the knowledge-based network structure based on social network analysis method, and measure three features of the knowledge-based network, that are density, centralization and structure hole. We test the relationship between three network features and dual innovation performance through negative binomial regression method. The results indicate that there is an inverted U-Curve relationship between density and exploitative innovation performance. There is an inverted U-curve relationship between centralization and exploratory innovation performance. There is an inverted U-curve connection between the structure hole and the dual innovation performance.

Published: February 2022

Polylactide stereocomplex (ST) of poly(L-lactide) (PLLA) and poly(D-lactide) (PDLA) (PLLA:PDLA 50:50) was blended with poly(methyl methacrylate) (PMMA) 10 – 50 wt.%. The materials were dissolved in chloroform at room temperature and the films were then cast. Differential scanning calorimetry showed a stereocomplex melting peak at 208 °C – 50 °C higher than that for neat PLLA or PDLA - confirming the polylactide stereocomplex crystallites. The PMMA content ratio of 10 – 50 wt.% in the stereocomplex showed almost complete stereocomplex crystallites. A peak at about 908 cm-1 in Fourier transform infrared spectra further confirmed the stereocomplex crystallites which indicated that PMMA could blend and efficiently bond with the stereocomplex. The X-ray diffraction analysis showed that the stereocomplex crystallinity became smaller when PMMA was added. Morphology from scanning electron microscopy revealed that phases separated in the ST/PMMA blend when the amount of PMMA was increased. Adding PMMA to stereocomplex films led to an increased elongation at break which peaked at 30 % added PMMA. Increased PMMA also led to the improved thermal stability of the stereocomplex. These properties and higher toughness are also needed in common applications, in particular films for packaging and protection of manufactured products.
Akzeptanz technologischer Innovationen im M-Commerce
Authors: Sassmann Oliver
Published: February 2022

Many innovations do not succeed on the market despite good preconditions. In addition to rational reasons such as high prices or quality problems, psychological - often unconscious - resistance to the acceptance of an innovation is also responsible for the reluctance of consumers. The investigation of these psychological resistances to acceptance and the development of a comprehensive model of acceptance based on behavioral science is the subject of this thesis. This closes gaps of the theoretical work of acceptance research and new insights of how to implement and use of innovations can be promoted on the consumer side will be provided.
Potential Utilization of Insect Meal as Livestock Feed
Authors: Moyo Sipho , Moyo Busani
Published: February 2022

Globally, the utilization of alternative protein sources in livestock feed has been extensively deliberated and established to be the best novel approach. Extensive research indicated that insects provide good opportunities as a sustainable, high quality, and low-cost component of animal feed. The use of insects in animal diet sounds to be the prospective opportunity leading to sustainability of animal feeds and meet the intensifying worldwide plea for livestock products. The value of these protein sources has, however, increased due to limited production, competition between humans and animals. The use of insects for feeding farmed animals represents a promising alternative because of the nutritional properties of insects and the possible environmental benefits, given the sustainability of this type of farming. Yet little has been documented about the nutrient composition of various insect meals, the impact of insect meal in the animal feed industry, safety, and attitude and willingness of farmers to accept insect-based animal feed and food. Therefore, this chapter seeks to document the potential utilization of insect meal as livestock feed.

Published: February 2022

This chapter addresses the view synthesis of natural scenes in virtual reality (VR) using depth image-based rendering (DIBR). This method reaches photorealistic results as it directly warps photos to obtain the output, avoiding the need to photograph every possible viewpoint or to make a 3D reconstruction of a scene followed by a ray-tracing rendering. An overview of the DIBR approach and frequently encountered challenges (disocclusion and ghosting artifacts, multi-view blending, handling of non-Lambertian objects) are described. Such technology finds applications in VR immersive displays and holography. Finally, a comprehensive manual of the Reference View Synthesis software (RVS), an open-source tool tested on open datasets and recognized by the MPEG-I standardization activities (where “I” refers to “immersive”) is described for hands-on practicing.

Due to the important advancement and the accumulation of new evidence on the periodontitis-cardiovascular disease (CVD) relationship as well as the major medical, economic and social burden caused by both diseases this chapter aims to review existing epidemiological and pathogenetic links related to this topic. Also, this chapter aims to highlight the impact of the periodontitis-CVD relationships on clinical practice and on the preventive approaches targeting to decrease the impact of periodontitis on CVD. Periodontitis is an infectious disease eliciting local and general inflammation, which leads to periodontal destruction and systemic involvement. Several pathways could explain the link between periodontitis and CVD such as bacteraemia, chronic persistent systemic inflammation and oxidative stress. The first step in the treatment of periodontitis addresses the elimination of microbial components, which lead to a decrease in local and systemic inflammation. Periodontal therapy seems to positively impact CVD. Specialists should inform patients with CVD on the negative impact of periodontitis on their systemic status and refer patients to the periodontist for an extensive examination as routine management of CVD. Some possible risks of periodontal therapy should be considered in patients undergoing antithrombotic medication.
Cerebrospinal Venous Obstruction: Anatomy, Clinical Presentation, Diagnosis, and Treatment of Chronic Infective Cerebrospinal Venulitis
Authors: K. Thibault Paul
Published: February 2022

This review chapter describes the normal anatomy and function of the cerebrospinal venous system, ultrasound diagnosis of obstructions in the system, and the clinical implications and treatment of chronic cerebrospinal venous obstruction (CCSVO) associated with chronic persistent Chlamydophila pneumoniae (Cpn) infection. The normal patterns of flow in the cerebrospinal venous system are described and guidelines for the interpretation of the extracranial duplex ultrasound (ECDU) examination of the neck veins are presented. An infective cause of CCSVO is proposed and relevant pathology tests necessary for a diagnosis of chronic persistent Cpn venulitis are discussed. A treatment protocol for Cpn chronic venulitis is described and recommended. The progress of the patient with CCSVO can then be followed and monitored by using the ECDU and relevant pathology tests after 3 and 6 months. CCSVO is a relatively common condition encountered in chronic diseases of unknown etiology and is often neglected by medical practitioners when managing patients with symptoms of brain fog, chronic headaches, and fatigue. Objective diagnostic and treatment protocols are required to make further progress with these conditions.

Phycological debriefing in acute traumatic events: Evidence synthesis
Authors: Arancibia Marcelo , Leyton Fanny , Morán Javier , Muga Andrea , Ríos Ulises , Sepúlveda Elisa , Vallejo-Correa Valentina
Published: February 2022

Stressful life situations can generate chronic symptomatology, so it is of great concern to analyze preventive strategies. Psychological debriefing is an intervention for acute trauma, which verbalizes perceptions, thoughts, and emotions experienced during a recent traumatic event. The evidence surrounding its efficacy is controversial. This article discusses the efficacy of psychological debriefing based on systematic reviews and clinical practice guidelines. In all, nine systematic reviews were included. Only one of them found that psychological debriefing effectively decreased psychological stress, while the remaining eight found no significant effects for outcomes such stress, depressive and anxious symptoms, or development and severity of post-traumatic stress disorder. Moreover, two clinical trials found that the intervention had a significantly deleterious effect. Another study found a worsening in the symptomatology associated with the event. Of the eight clinical practice guidelines incorporated, none recommended psychological debriefing as an intervention for acute trauma. Some phenomena could explain the lack of success of the intervention in the scientific evidence. The bioethical conditions related to the traumatic scenario hinder its research, and its lack of standardization makes its evaluation in clinical trials problematic. Other variables such as ethnicity, personality, culture, gender, and history of traumatic experiences have been little considered in research. Nevertheless, the intervention may hinder the adequate processing of traumatic memory and emotions. Current evidence is consistent in not recommending psychological debriefing as an intervention for acute trauma, so its management should avoid it. It is suggested to promote research on preventive interventions to develop chronic traumatic symptomatology.
Auto-routing Methods for Complex Ship Pipe Route Design
Authors: Bian Xuanyi , Lin Yan , Dong Zongran
Published: February 2022

Pipe route design is one of the most complex and time-consuming steps in the ship detailed design. A large number of scholars have studied the optimization of ship pipe routes, but there is still a lack of a fast and effective method for the automatic design of complex pipe routes. For this reason, this article proposes the auto-routing methods of single pipes, branch pipes, and multipipes. The auto-routing methods are based on an Improved A* algorithm. Compared with the traditional A* algorithm, the Improved A* algorithm considers the constraints of ship pipe route design. And by introducing “Blocking Iteration” and dynamic weight, the accuracy and efficiency of the algorithm are improved. On this basis, this article uses Python and OpenGL to develop the automatic pipe route design system. The system supports the automatic pipe route design, visualization of optimization results, and two-way interaction with three-dimensional (3-D) design software. Finally, the practicability of the proposed methods and system is verified by the simulation on a comparison case and an actual fuel filling and transfer pipe system.

Published: February 2022

Slovenia is one of the countries that have been most affected by the autumn/winter 2020/21 wave of the COVID-19 pandemic regarding the incidence and excess mortality among the general population as well as regarding the incidence among health care workers and nursing personnel. The World Health Organization has underestimated the importance of the airborne spread of SARS-CoV-2 and the recommended safety measures have not been entirely sufficient. When people breathe, talk, sing, cough, or sneeze, they emit respiratory droplets of various sizes, most of which are always smaller than 1 μm. Respiratory droplets smaller than 5 μm stay airborne in indoor spaces for a long time and travel over distances much longer than 2 m. Thus, an infected person in an indoor environment creates an infectious aerosol that may infect other people without close interpersonal contact. This short review presents the mathematical model and internet application by authors from the Massachusetts Institute of Technology for calculating the safe time before probable airborne infection occurs in indoor spaces. The importance of ventilation, air filtration, air humidity, and air disinfection by ultraviolet light is briefly discussed. The principles of preventing the airborne spread of SARS-CoV-2 are summarized.
NATURE- AND BIO-INSPIRED OPTIMIZATION: THE GOOD, THE BAD, THE UGLY AND THE HOPEFUL

Published: February 2022

Nowadays, optimization has become an important issue for industrial systems and product development. From an engineering perspective, optimization implies adjusting or fine tuning the design of the system considering performance factors. Unfortunately, in many real-world problems there are no mathematical techniques capable of solving them within reasonable times. Consequently, optimization is done manually in many practical cases.
Over the last decades many meta-heuristic optimization techniques have been inspired by natural phenomena and behavioral patterns observed in animals. As such, nature- and bio-inspired optimization allows optimizing a problem without requiring special knowledge about it, but only the fitness function to optimize and mechanisms to create possible solutions. Bio-inspired optimization techniques generate new candidate solutions intelligently in search for the best one for the problem. Although they do not guarantee to obtain the optimum solution, they can autonomously achieve good results within reasonable time, having been successfully used in manifold real-world problems.
There are so many bio-inspired optimization proposals in the literature that it could be overwhelming to choose one. This research area is expanding every year, with more bio-inspired techniques, and tools devised to use them in real applications. However, not all bio-inspired solvers are interesting. Many proposals are mathematically similar to well-established meta-heuristics, so they could render equally similar results. Furthermore, the performance of many of them has not been rigorously confirmed by experimentation.
This article elaborates on recent applications (the good), the lack of innovation of new metaphor-based algorithms (the bad), poor methodological practices (the ugly) and the exciting future of opportunities and challenges (the hopeful) of this research area. Nature- and bio-inspired optimization can be great alternatives to optimize complex processes in many real-world industrial problems. But above all, the use of bio-inspired solvers requires a global understanding on the current status of this area. Providing such an overarching view to the audience from a multi-faceted perspective is the ultimate purpose of this manuscript.

Commercial substrates have the greatest application in the production of ornamental flowers. Depending on the species being produced, there is an adequate substrate for each production. Thanks to a wide range of commercial substrates, they can be completely adapted to the type of plants, and provide everything they need in the most sensitive stage of life, as well as in the later stages. The research is based on the possibilities and effectiveness of different substrates on growth and development of roots and above ground parts of the Globe amaranth (Gomphrena globosa L.), in the seedling phase and in the adult plant phase. The research was conducted in the "Gornja Puharska" Nursery in Prijedor during 2019. The substrates used in the experiment are the mixture of garden soil, Baltic, and peat from Grahovo, Hawitta baltisches UBI 20 Tonsubstrat 2, and Klasmann-Deilmann - TS3 Medium basic substrate. Measurements of morphological parameters of growth and development of plants (the plant height, number of leaves and flowers, and flower diameter) were performed, as well as determination of weight of fresh and dry roots and above groundarts and the number of seeds. Effect of medium basic substrate is reflected in an increase in the average value of vegetative morphological parameters (the plant height and number of leaves) of Globe amaranth seedlings and adult plants. Furthermore, this substrate had a positive effect on both fresh and dry mass of adult plants, as well as the number of obtained seeds, compared to the other two substrates. Efficiency of substrate comprising a mixture of garden soil, Baltic, and peat from Grahovo, is reflected in an increase in the average values of generative morphological parameters (the number of flowers and flower diameter) of the Globe amaranth - Gomphrena globosa L., compared to commercial substrates applied.

Soybean yield depends on the selection of cultivars, soil fertility, applied cultivation practices, and agroclimatic conditions over the years. High-quality and timely primary tillage is essential for stable development and high yields of soybean plants. The effect of autumn and spring primary tillage on soybean yield and 1000-grain weight was examined in a three-year study (2013-2015). The trial included cultivars with different maturity periods, developed at the Institute of Field and Vegetable Crops Novi Sad: Valjevka and Galina 0 maturity group, Sava and NS Maximus I maturity group, Rubin and Venera II maturity group. Trial subplots were prepared using different periods of primary tillage, which was conducted in autumn (November, 01–05) and spring (March, 25–31). The highest yields and 1000-grain weight were obtained after autumn primary tillage in all the three study years. Yield decrease by 2.72% to 38.91% and 1000-grain weight decrease of 1.33%-11.93% were recorded after spring primary tillage.

Sweet cherry (Prunus avium L.) fruits are characterised by a short shelf life. To extend the shelf life, pre-storage hydrocooling is carried out to reduce their temperature before storing them in the cold storage. During 2015 and 2016, hydrocooling treatment on fruits of two sweet cherry cultivars, 'Kordia' and 'Regina', from orchards on the locality of Trebinje, was performed. Samples of both cultivars were subjected to hydrocooling treatment in an automatic hydrocooling system at a temperature of 0.9 ºC for 10 minutes. The treated fruits were subjected to a cooling process before being placed in the cold storage, and the control fruits were put into the cold storage without hydrocooling. The fruits were placed for 15 days in NA cold storage at a temperature of 1 ºC and humidity of 85-95%. Analysis of fruit mass, colour, and firmness was performed on fruits after harvest and after storage. The results showed a significant positive effect of hydrocooling on fruit mass, i.e., treated fruits had less loss compared to the control fruits. The same fruits had higher fruit flesh firmness during cold storage. The fruit skin had the highest intensity of red colour in the harvesting time, while in treatment and control fruits in both years the intensity of the colour decreased during the cold storage. The year showed to have an impact on all examined characteristics of fruits of both cherry cultivars.

Graphene, a special two-dimensional material, has a unique band structure that allows the type and concentration of carriers to be controlled through a gate voltage, and it has potential applications in bipolar nanoelectronic devices. In this paper, based on the tight-binding model of graphene p-n junctions, by using the nonequilibrium Green’s function method and Landauer-Büttiker formula, the thermal dissipation of electric transport in graphene p-n junctions in a magnetic field is investigated. Under a strong magnetic field, both sides of the junction are in the quantum Hall regime, thus the topologically protected chiral edge states appear. Intuitively, the topologically protected chiral edge states are dissipationless. However, the results show that thermal dissipation can occur in the quantum Hall regime in graphene junctions in the presence of dissipation sources, although the topologically protected chiral edge states still exist. In clean graphene junctions, thermal dissipation occurs mainly at the edge for the unipolar transport, but it occurs both at the edge and at the interface of the junctions for the bipolar transport. In the presence of disorder, thermal dissipation is significantly enhanced both in the unipolar junction and in the bipolar junction, and it increases with disorder strength increasing. Besides, the energy distribution of electrons at different positions is also studied, which shows that the thermal dissipation always occurs as long as the energy distribution is in nonequilibrium. This indicates that the topology can protect only the propagation direction of electrons, but it can not suppress the occurrence of thermal dissipation.

Pod size is an important yield-influencing trait in peanuts. It is affected by plant hormones and identifying the genes related to these hormones may contribute to pod-related trait improvements in peanut breeding programs. However, there is limited information on the molecular mechanisms of plant hormones that regulate pod size in peanuts. We identified a mutant with an extremely small pod (spm) from Yuanza 9102 (WT) by 60Co γ-radiation mutagenesis. The length and width of the natural mature pod in spm were only 71.34% and 73.36% of those in WT, respectively. We performed comparative analyses for morphological characteristics, anatomy, physiology, and global transcriptome between spm and WT pods. Samples were collected at 10, 20, and 30 days after peg elongation into the soil, representing stages S1, S2, and S3, respectively. The differences in pod size between WT and spm were seen at stage S1 and became even more striking at stages S2 and S3. The cell sizes of the pods were significantly smaller in spm than in WT at stages S1, S2, and S3. These results suggested that reduced cell size may be one of the important contributors for the small pod in spm. The contents of indole-3-acetic acid (IAA), gibberellin (GA), and brassinosteroid (BR) were also significantly lower in spm pods than those in WT pods at all three stages. RNA-Seq analyses showed that 1,373, 8,053, and 3,358 differently expressed genes (DEGs) were identified at stages S1, S2, and S3, respectively. Functional analyses revealed that a set of DEGs was related to plant hormone biosynthesis, plant hormone signal transduction pathway, and cell wall biosynthesis and metabolism. Furthermore, several hub genes associated with plant hormone biosynthesis and signal transduction pathways were identified through weighted gene co-expression network analysis. Our results revealed that IAA, GA, and BR may be important regulators in controlling pod size by regulating cell size in peanuts. This study provides helpful information for the understanding of the complex mechanisms of plant hormones in controlling pod size by regulating the cell size in peanuts and will facilitate the improvement of peanut breeding.
Lattice Systems
Authors: Simon Barry , van Enter Aernout
Published: February 2022

Lattice systems form a widely studied class of models originating in statistical mechanics, and consisting of single‐site observables (functions or operators) describing “spins,” living on infinite lattices. They have found applications in various other fields, in physics (e.g., field theory), mathematics (dynamical systems and probability theory), and also as models for epidemics and populations. Their major interest and difference with other stochastic processes is due to the occurrence of various phase transitions, where the dependence on parameters becomes nonsmooth, and/or the number of measures associated with a certain parameter can change.

Purpose

The recently worldwide standard measurement of electron beam reference dosimetry include the International Atomic Energy Agency (IAEA) Technical Report Series (TRS)‐398 and Association of Physicists in Medicine (AAPM) Task Group (TG)‐51 protocols. Muir et al. have modified calibration methods for electron beam calibration based on AAPM TG‐51. They found that the use of cylindrical chambers at low energy gave acceptable results. In this study, we propose and report a modified calibration for electron beam based on IAEA TRS‐398, the standard reference dosimetry protocol worldwide.

Methods

This work was carried out with energies of 6, 8, 10, 12, and 15 MeV. The electron beam is generated from Elektra Synergy Platform and Versa HD linear accelerator. The charge readings were measured with PTW 30013, IBA CC13, Exradin A1Sl, and Exradin A11 chambers connected to the electrometer. The dose calculation uses an equation of modified calibration for electron beam using the updated factor in previous work. The absorbed dose to water for electron beam is expressed in dose per monitor unit (cGy/MU). Thus, we compared dose per monitor unit (D/MU) calculation using a modified calibration to TRS‐398.

Results

In this work, we have succeeded in implementing the modified calibration of electron beam based on TRS‐398 by applying a cylindrical chamber in all energy beams and using the updated factor. The ratio of the absorbed dose to water between original and modified calibration protocols of TRS‐398 (Dw) for the cylindrical chamber was 1.002 on the Elekta Synergy Platform and 1.000 on the Versa HD while for the parallel‐plate chamber it was 1.013 on the Elekta Synergy Platform and 1.014 on the Versa HD. Based on these results, both the cylindrical and parallel‐plate chambers are still within the tolerance limit allowed by the TRS‐398 protocol, which is ±2%. Therefore, modified calibration based on TRS‐398 gives acceptable results and is simpler to use clinically.
