Authors: Ma Yaping , Devi Mura Jyostna , Song Lihua , Gao Handong , Cao Bing
Published: August 2022

Ailanthus altissima is a deciduous tree native to China and introduced to other parts of the world as an ornamental plant. It exhibits resistance to both abiotic and biotic stress factors and has various pharmacological effects and strong allelopathy, generating significant research interests. However, the genome sequence of this species has not been reported, limiting its research development. The purpose of the study was to determine the genome size and characteristics of A. altissima to conduct its genomic survey. Next-generation sequencing and K-mer analysis were employed to measure the genome size of A. altissima. Overall, a total of 61.93 Gb high-quality clean data were acquired, representing approximately 64.09× coverage of the A. altissima genome. The genomic characteristics of A. altissima include a genome size of 966.38 Mbp, a heterozygosis rate of 0.78 %, and a repeat rate of 41.22 %. A total of 735,179 genomic SSRs markers were identified based on genome survey sequences. Alignment analysis showed that A. altissima was closely related to Citrus sinensis and Leitneria florida-na. This study provides basic information for future whole-genomic sequencing of A. altissima. This will facilitate a knowledge of the population structure, genetic diversity, long distance-gene transfer, and pollen-based gene flow analyses of A. altissima populations from its known distribution ranges in China, focusing on planted and natural forest stands.
I. A. Richards on Communication and Rhetoric: The “New” Rhetoric of The Philosophy of Rhetoric
Authors:   Institute of British & American Studies Center for International Area Studies Hankuk University of Foreign Studies, Park WooSoo
Published: August 2022

I.A. Richards’ deep interest in the communicative function of language and poetry is manifest from his early scholarly career to the last. For Richards, poetry itself is a mode of communication. Since he argues that there is no difference in kind between aesthetic experience and everyday common experience, what matters in poetry is the communication of complex impulses from poet to reader placed in common linguistic situations and efficacy. Interpretation and understanding of the attributes of a language are prerequisite and inevitable for a fulfilled communication and communion of men. His “close reading” is a speculative instrument to read with and to think with. Richards applies his view of a poetic language to his philosophy of the “new” rhetoric. His new or improved rhetoric aims to remedy misunderstandings in communication, mainly due to misinterpretation of ambiguous meanings and verbal contexts and purposes. Metaphoricity is the very source of a language. Rhetoric in Richards shifts its focus from speaker to audience, and an effective communication requires from both the speaker and the listener Confucian sincerity in authentic feelings and intents. By enlarging and idealizing his rhetorical functions to the extent of self-development and self-completion by means of verbal communication, Richards unfortunately disregards the ideological dynamics of language and social beliefs, already and always superimposed on the speaking subject. His contextual theory of meaning is still stinted by his empirical positivism and psychologism. However, Richards unites poetics and rhetoric in his theory of communication and comprehension.
Elizabeth Bishop’s Skeptical View of Christianity: Focusing on “Brazil, January 1, 1502”
Authors:   Institute of British & American Studies Center for International Area Studies Hankuk University of Foreign Studies, Song Yoon
Published: August 2022

This paper aims to re-read Elizabeth Bishop’s poem “Brazil, January 1, 1502” from the viewpoint of religious skepticism. Containing a number of Biblical and religious connotations, this poem depicts the Portuguese colonizers arrived at Brazil in the past. Bishop criticizes those who tended to appropriate Christian religion for their selfish benefits and ends to their worldly taste. The religious secularization portrayed in the poem would be usually alluded through natural things, particular words and colors. To discuss Bishop’s skeptical view of Christianity in this poem, I cite some Biblical stories and Christian materials and go on exploring the symbolic meanings of colors in relation to Christianity. Analyzing the poem in terms of religious skepticism, I try to invite readers to re-consider and expand the critical scope of the poetry of Elizabeth Bishop that didn’t garner the critical attention in terms of religion. I conclude that religious skepticism for Bishop becomes an angle of viewing and speculating the world and her age, hoping to broaden the horizon of Bishop studies and the landscape of modernism.

Published: August 2022

Las hormigas presentes en los cafetales podrían estar ejerciendo un control natural de la broca del café (BDC), como es el caso de Hypothenemus hampei al depredar a las poblaciones de esta plaga, que quedan en frutos abandonados al final de cada cosecha. El objetivo de esta investigación fue evaluar la capacidad depredadora de dos especies de hormigas (Solenopis picea y Crematogaster crinosa) sobre la broca del café con un atrayente en experimentos de campo. Para cada especie, se establecieron diez unidades experimentales (UE) con diez granos de café infestados con broca. Los granos infestados fueron colocados dentro de una malla de anjeo y colgados en árboles de café con un nido de hormigas. Para atraer las hormigas hacia los granos brocados estos fueron asperjados con una solución atrayente. Como testigo absoluto se usaron los mismos tratamientos con exclusión de hormigas y como testigo relativo granos brocados sin atrayente. La tasa de depredación de S. picea después de 24 h fue de 78,3%, seguida por C. crinosa con 34,3 %. El cebo atrayente incrementó en un 22 % la atracción de hormigas y depredación de estados biológicos de broca en cada UE, frente al tratamiento no asperjado. Los resultados muestran que las especies de hormigas evaluadas redujeron las poblaciones residuales de H. hampei; S. picea más que C. crinosa.

Disaster mitigation is a series of efforts to reduce disaster risks through physical development, awareness, and capacity building to face disaster threats. Appropriate communication strategies are needed to increase awareness and the ability to cope with disasters. Delivering appropriate, accurate, and reliable messages can build a reliable disaster literacy community. This study aimed to examine disaster mitigation literacy based on the local wisdom of indigenous people in Pangandaran Regency, West Java. The descriptive qualitative method was employed to explain the phenomena and events occuring in the field comprehensively. Data were collected through interviews, observation, and literature study. Meanwhile, the data were analysed systematically through reduction, presentation, and conclusion stages. The key informants were traditional figures in Badud and Pananjung Villages. The results showed that some traditions contain moral, social, and spiritual messages about disaster mitigation. This study concludes that the local wisdom of the Pangandaran community is an appropriate communication strategy to build disaster mitigation literacy.
Newspaper digital transformation in Medan: Analysis of SWOT and existence
Authors: Rasyid Abdul
Published: August 2022

The era of digital technology demands adjustments for print mass media entrepreneurs to maintain the continuity of their production and marketing. On the other hand, many people still depend on their interest to continue reading the printed version of the newspaper, given the limitations of internet access and the affordability of using a smartphone. This study aims to determine the existence of newspapers or printed newspapers in the city of Medan and the factors that influence their development and implications for public literacy through printed newspapers. This research method uses qualitative research using a content analysis approach by observing the production figures of printed newspapers, the amount of advertising revenue, and critical analysis of literacy issues. The results showed that the daily printed newspapers in Medan, which amounted to 30 newspapers, were in critical condition and estimated to be closed in 2040. The advertising supply at the heart of newspapers declined drastically to the lowest level. The political economy theory of media put forward by Garnham clearly shows that the mass media, including the printed mass media of newspapers, is closely related to economic problems. This means that the mass media of letters will not be able to live without the support of economic power, and of course, it has implications for the level and quality of literacy of those who read through printed newspapers.
Development of the Electricity Demand Response Mechanism for Renewable Integration and Consumer Engagement in Latvia. Summary of the Doctoral Thesis
Authors:   ,   Rīga Stradiņš University, Siliņeviča Veronika
Published: August 2022

The key principle of electricity market design is the maximisation of public welfare. In the context of rational electricity consumption, social welfare is the sum of consumer surplus, supplier surplus and congestion rents in order to maximise the benefits to society. For decades, the importance of balancing supply and demand has been emphasised in discussions on the security of the electricity sector. It has been reasonably assumed that electricity demand is inelastic, mainly by studying supply potential. However, the current understanding of supply and demand in the electricity system needs to address the three main challenges of European energy policy: sustainability, security of supply and competitiveness, while guaranteeing fairness in energy distribution. The aim of the research is to develop a conceptual framework for the integration of renewable energy sources and consumer involvement, based on the technology of a Demand Response aggregator – an information and technology company – in the Latvian electricity sector. The Thesis consists of an introduction, four chapters, conclusions, recommendations and a bibliography. The introduction explains the actuality of the research topic, defines the aims and objectives of the research, its subject and object, puts forward the research hypothesis, and determines the scientific novelty and practical significance of the research. In the first and second chapters, a theoretical and methodological framework, economic and institutional foundations and peculiarities of Demand Response in the energy sector, electricity price factors, the new role of electricity end-users and the possibilities of optimising demand response are provided. In the third chapter, the author analyses the macroeconomic and physical indicator trends of the energy sector, the renewable energy sources and electricity system prices, calculates approximate dependence formulae and coefficients of determination; develops a methodology for a comprehensive analysis of correlation and regression dependence of physical and system price indicators of the electricity sector based on an appropriate adaptation of classical mathematical models, and contributes to the literature on the impact of the state aid on the electricity market. In the fourth chapter, the author has proposed and developed a new two-level technical model for optimisation of demand response services, which proposes to solve the problem of reducing electricity consumption in the first stage and, in the second stage, to solve the optimisation problem of which group of active consumers' loads to disconnect in case of electricity shortages, thus, to respond to electricity market prices. The main text of the Thesis is 155 pages. The bibliography contains 137 sources. Additionally, 48 tables, 31 figures and 2 annexes are included in the Thesis.

Bistable spin-state switching characteristic of a charge-neutral iron(II) complex

Published: August 2022

Spin-crossover (SCO) complexes that show abrupt and hysteretic spin-state switching characteristics—termed as bistable spin-state switching—are proposed suitable to realize molecule-based switching and memory elements. For realistic applications, spin-state switching needs to be demonstrated in the thin film state, requiring vacuum sublimation of SCO complexes to fabricate clean and impurity-free thin films. Charge-neutral iron(II) complexes are a class of SCO complexes that are reported to undergo sublimation, and their spin-state switching characteristics in the thin film state have been studied. However, hysteretic SCO in the thin film state is a scarcely observed phenomenon, requiring the development of iron(II) charge-neutral complexes that can undergo bistable spin-state switching in the bulk and thin film states. Herein, we report a new iron(II) charge-neutral complex—[Fe(H2Bpz2)24,4'-Br2-bpy] (H2Bpz2 = di¬hydro¬bis¬(pyrazol-1-yl)borate; 4,4'-Br2-bpy = 4,4'-dibromo-2,2'-bipyridine)—that undergoes abrupt and hysteretic spin-state switching in the bulk-state with T1/2 = 113 K and ΔT1/2 = 13 K at a scan rate of 0.25 K/min. The HS-to-LS switching of the complex is scan-rate-dependent, whereas the LS-to-HS switching is scan-rate-independent. Moreover, a reverse-SCO phenomenon was observed upon heating the sample in the 78 K-105 K temperature range at a scan rate of 3 K/minute. However, the reverse SCO was not observed when the complex was studied at scan rates of 1 and 0.5 K/min. Such observations indicate the presence of a kinetically trapped HS-fraction (frozen-in effect) during the HS-to-LS switching, when the sample was studied at the scan rate of 3 K/min. Crucially, the complex can be sublimed; efforts are on to elucidate the nature of SCO in the thin film state. Overall, a simple and easy to prepare sublimable complex—[Fe(H2Bpz2)24,4’-Br2-bpy]—shows bistable spin-state switching characteristics that can be leveraged to fabricate spin-state switchable thin film architectures.
Computations Reveal a Crucial Role of an Aromatic Dyad in the Catalytic Function of Plant Cytochrome P450 Mint Superfamily
Authors: Kardam Vandana , Kalita Surajit , Dubey Kshatresh
Published: August 2022

Enzymes are highly specific for their native functions, however with advances in bioengineering tools such as directed evolution, several enzymes are being repurposed for the secondary function of contemporary significance. Due to the functional versatility, the Cytochrome P450 (CYP450) superfamily has become the ideal scaffold for such bioengineering. In the current study, using MD molecular dynamics) simulations and hybrid QM/MM (Quantum mechanics/molecular mechanics) calculations, we have studied the mechanism of spontaneous emergence of a secondary function due to a single site mutation in two plant CYP450 enzymes from the mint family. The MD simulations of WT (wild type) CYP71D18 and CYP71D13 enzymes and their variants show a crucial gating mechanism by aromatic dyad formed by Phe121 and Phe363 which regulates the substrate recognition. The QM/MM calculations reveal that the hydroxylation reactions at C3 and C6 positions in WT CYP71D18 and CYP71D13 enzymes as well as their variants follow a hydrogen atom transfer (HAT) followed by a single electron transfer (SET) mechanism, which is different from the typical rebound mechanism shown by most of the CYP450 enzymes.
Computational evolution of new catalysts for the Morita–Baylis–Hillman reaction
Authors: Seumer Julius , Jensen Jan H.
Published: August 2022

We present a de novo discovery of an efficient catalyst of the Morita–Baylis–Hillman (MBH) reaction by searching chemical space for molecules that lower the estimated barrier of the rate determining step using a genetic algorithm (GA) starting from randomly selected tertiary amines. We performed five independent GA searches that resulted in 448 unique molecules, for which we were able to locate 435 true transitions states at semiempirical level of theory. The predicted activation energies of all 435 molecules where all lower than that of DABCO, which is a popular catalyst of the MBH reaction. Virtually all the molecules contain an aziridine N as the catalytically active site, which is discovered by the GA since it is either not found in the initial population or discarded early only to be redisovered as the search progresses. Many of the GA searches also introduce a substituent with a hydrogen bond donor that helps to stabilize the transition state and thus lower the barrier. Two molecules are selected for further study based on their synthetic accessibility as predicted by the retrosynthesis package Manifold. For these two molecules we compute the entire free energy reaction profile at the DFT level and show that their rate determining barriers are 1.7 and 2.4 kcal/mol lower than that of DABCO. The molecule with the lowest barrier has higher barriers for the other steps compared to DABCO, but none of the barriers are competitive with the rate-determining barrier and is predicted to outperform DABCO. This demonstrates the power of free exploration of chemical a space compared to more constrained fragment-based approaches.

The conserved Pelado/ZSWIM8 protein regulates actin dynamics by promoting linear actin filament polymerization
Authors: Molina-Pelayo Claudia , Olguin Patricio , Mlodzik Marek , Glavic Alvaro
Published: August 2022

Actin filament polymerization can be branched or linear, which depends on the associated regulatory proteins. Competition for actin monomers occurs between proteins that induce branched or linear actin polymerization. Cell specialization requires the regulation of actin filaments to allow the formation of cell type–specific structures, like cuticular hairs inDrosophila, formed by linear actin filaments. Here, we report the functional analysis of CG34401/pelado, a gene encoding a SWIM domain–containing protein, conserved throughout the animal kingdom, called ZSWIM8 in mammals. Mutantpeladoepithelial cells display actin hair elongation defects. This phenotype is reversed by increasing actin monomer levels or by either pushing linear actin polymerization or reducing branched actin polymerization. Similarly, in hemocytes, Pelado is essential to induce filopodia, a linear actin-based structure. We further show that this function of Pelado/ZSWIM8 is conserved in human cells, where Pelado inhibits branched actin polymerization in a cell migration context. In summary, our data indicate that the function of Pelado/ZSWIM8 in regulating actin cytoskeletal dynamics is conserved, favoring linear actin polymerization at the expense of branched filaments.
Patient satisfaction of orbital prosthesis fabricated by the aid of rapid prototyping technology versus conventional technique in orbital defect patients: A crossover randomized clinical trial
Authors: Abd El Salam Sara Eman , Eskandar Ashraf , Mohammed Khaled
Published: August 2022

Purpose: This study is to compare two types of orbital prosthesis fabrication techniques, the indirect rapid prototyping (RP) technology versus the conventional technique regarding; patient satisfaction and dimensional accuracy.
Material and Methods: Eight patients with orbital defects (age range 10-45 years) were selected to be included in a cross-over randomized trial. The patients were divided into two equal groups: Group A patients (n=4) received an orbital prosthesis constructed by conventional technique followed by another one constructed by rapid prototyping technology. Group B patients (n=4) received the same treatment as the first group but in a reversed order. Patient satisfaction was evaluated through questionnaire while dimensional accuracy in comparison to the normal side was calculated for both techniques. Numerical data were analyzed using Kolmogorov-Smirnov and Shapiro-Wilk tests. For parametric data; Paired t-test was used to compare between prostheses and the normal side. For non-parametric data; Wilcoxon signed-rank test was used to compare between the two techniques.
Results: Orbital prostheses made by aid of RP technology showed statistically significant higher mean satisfaction score than the conventional technique (P ≤ 0.05), both prostheses showed insignificant less eye fissure height dimensions in comparison to normal side but conventional technique showed significant less eye fissure length.
Conclusion: Rapid prototyping technology improved patient`s satisfaction regarding the orbital prosthesis and it was proved to be superior than conventional technique in dimensional accuracy. (Int J Maxillofac Prosthetics 2019;1:27-32)
A Literature Review on the Efficacy of Injectable Neuroleptics in the Treatment of Schizophrenia
Authors: Coward Erika , Clancy Madison , Pashkja Olivia
Published: August 2022

Introduction: Schizophrenia is a chronic brain disorder of which the cause is unknown. This disorder affects less than one percent of the population and involves symptoms such as hallucinations, delusions, disorganization, and negative symptoms. Treatment for schizophrenia is mainly used to alleviate symptoms of schizophrenia, therefore improving their quality of life. Injectable neuroleptics are frequently used in patients with schizophrenia to prevent relapses attributed to nonadherence. This literature review will examine the current and potential future uses of injectable neuroleptics as a treatment for individuals with schizophrenia.
Methods: This literature review was assembled using the PubMed, Google Scholar, and Science Direct databases to evaluate the efficacy of injectable neuroleptics for individuals with schizophrenia. Keywords for the search include: “neuroleptics”, “schizophrenia”, “risperidone”, “aripiprazole,” “clozapine”, “long-acting injections”, “treatment”, “clinical trial” as well as additional related keywords.
Results: In all of the RCTs identified in the reviewed studies, clozapine was considered the most effective in alleviating symptoms associated with schizophrenia although it did not affect the progression of the disorder.
Discussion: The literature discussing various injection neuroleptics has been shown to be safe and effective in treating symptoms of schizophrenia but has not been proven to be effective in the slowing of the progression of schizophrenia. As such, future research in this area would be beneficial to the scientific community. Given the limited number of studies, additional research is needed to assess the efficacy of long-acting injectable antipsychotics in slowing the progression of the disorder. One possible research avenue would involve the examination of a combination therapy of both injectable and oral neuroleptic treatments.
Conclusion: Long-acting injectable antipsychotics have been shown to be effective in alleviating many of the debilitating symptoms for individuals with schizophrenia. Further studies are needed to evaluate the most effective method of treating the progression of this disorder, such as combination therapy using both injectable as well as oral antipsychotics.

Authors: Kim Seongjung , Nam Sangwook
Published: August 2022

In this study, a modular array antenna with low mutual coupling is proposed for operation in a Ku-band (12–18 GHz) reconfigurable array, which consists of a ground frame board, element blocks, spacing blocks, and connecting rods. The modular element blocks can be freely mounted at any positions on a 46 × 9 grid on the ground frame board. The proposed modular array structure can be used to easily check the performance of different array structures by changing the element positions due to its low mutual coupling characteristics. An expanded view of the proposed array antenna structure is also provided, showcasing how the antenna modules, ground modules, base ground, ground frames, and aluminum rods have been constructed. The value of mutual coupling measured between the adjacent elements is less than -22.9 dB in the E-plane and -18.5 dB in the H-plane. Moreover, the measured radiation efficiency and gain patterns of the active element are shown.

The deployment of the millimeter (mmWave) frequency spectrum by fifth-generation (5G) device-to-device (D2D) wireless networks is anticipated to meet the growing demands for increased capacity. The antenna is regarded of as an important determinant that guarantees the maximum performance of wireless communication. This paper presents a low-profile magneto-electric (ME) dipole antenna for 5G mmWave D2D communication. A single-element quasi-loop radiator was designed to excite horizontal polarization, and a coaxial probe was used to produce vertical polarization. Subsequently, the structure of the radiator was transformed into a two-element quasi-loop antenna to achieve an omnidirectional radiation pattern with relatively enhanced gain. A coaxially fed T-junction microstrip element was implemented to equally distribute the signal between the two quasi-loop radiators and attain proper impedance matching. Furthermore, a pair of shorting pins was introduced into the two-element design to maintain the circularly polarized (CP) radiation. The finest values of the axial ratio and |S11| were derived by rigorously optimizing all the geometry parameters. Both single-element and two-element quasiloop antennas were fabricated and characterized experimentally on the air substrate. The advantage of avoiding a physical substrate is to realize a wide bandwidth, circumvent dielectric losses, and ascertain the maximum gain. The measured and simulated results agree thoroughly with each other. Stable in-band CP radiation were accomplished, thus confirming an appropriate field vector combination from the coaxial probe and the radiator. The finalized antenna engaged an area of ~7.6λ20 for operation at 23.9–30.0 GHz with an axial ratio <3 dB, radiation efficiency ~80%, and gain >5 dBic.

This paper presents a new circular monopole antenna with triple-band characteristics that can operate in both ultra-high frequency (UHF) and ultra-wideband (UWB) and can be integrated into a radio-frequency identification (RFID) system reader board. The antenna was built with a patch and a coplanar waveguide (CPW) feed microstrip line to meet the UHF/UWB bandwidth requirements for RFID applications. The designed antenna has a size of 70 mm × 60 mm × 0.8 mm. CST Microwave Studio simulations were used to validate the proposed antenna, which had a maximum gain of 4.8 dBi. Furthermore, the designed antenna had a radiation pattern that spanned the full working band. To interact with RFID tags, the antenna was built and installed into the RFID reader board. The simulation and measurement findings showed good agreement. Experiments indicated that the UHF-RFID performance of the monopole antenna was comparable to that of existing commercial solutions.
Wireless Power Transfer-Based Microrobot with Magnetic Force Propulsion Considering Power Transfer Efficiency
Authors: Kim Dongwook , Ahn Seungyoung
Published: August 2022

A microrobot that could continuously receive both electrical energy and propulsion force from a wireless power transfer system would offer tremendous benefits. However, wireless powering systems produce a time-varying magnetic field that can be harmful if the generated magnetic field needed for microrobot movement is large. To limit exposure, power transfer efficiency must be enhanced. This paper derived and analyzed the magnetic force applied to a microrobot from a wireless power transfer system. Unlike previously introduced Lorentz force-based microrobot propulsion, the proposed method is independent of a wireless power transfer system’s frequency. Therefore, this frequency can be determined considering maximum power transfer efficiency. The theoretical analysis and simulation by numerical analysis were compared, and results were verified though actual fabrication and measurement. Analyses of the transmitting and receiving coils were conducted. The optimum force, with less than 9% discrepancy, was determined while achieving a 3.6% improvement in power transfer efficiency.
Frequency Discrimination Method Using Asymmetric Transmission Time in FSK Radar
Authors: Sim Jae Young , Yang Jong-Ryul
Published: August 2022

A frequency discrimination method based on transmission time control is proposed for effective absolute distance measurement using frequency-shift keying (FSK) radar. In FSK radar, each frequency is transmitted for different durations using an asymmetric control signal. The phase difference at each frequency is effectively obtained by counting the different numbers of samples obtained after envelope detection in the baseband signal. The proposed method can easily and rapidly distinguish the phase difference for each frequency. This makes it simple to measure the absolute distance up to the maximum unambiguous range. The absolute distance measured using FSK radar with a frequency spacing of 150 MHz showed an accuracy of 97.08% in the full unambiguous range. The distance measurement results prove that the proposed method using FSK radar is useful for presenting the maximum unambiguous range.

Published: August 2022

The finite-difference time-domain (FDTD) method has been widely used for the electromagnetic analysis of dusty plasma sheath in reentering hypersonic vehicles. The time-varying characteristics of dusty plasma should be considered to accurately analyze THz wave propagation in dusty plasma. In this work, we propose an efficient FDTD modeling of time-varying dusty plasma based on the combination of the bilinear transform and the state-space approach. The proposed FDTD formulation for time-varying dusty plasma can lead to a significant improvement in computational efficiency against the conventional shift operator FDTD counterpart while maintaining numerical accuracy. Numerical examples are performed to validate the proposed FDTD modeling of time-varying dusty plasma.
Three-Dimensional Near-Field to Far-Field Transformation for Radar Cross Section Estimation of Elongated Targets via Subdimensional Hybrid Conversion
Authors: Kim Jeong-Kyu , Tae Hyun-Sung , Seo Min-Gyeong , Park Ho-Min
Published: August 2022

Image-based (IB) near-field to far-field transformation (NFFFT) is a useful method for the valid prediction of radar cross sections (RCSs) from short-range monostatic measurements. Many previous studies on the IB NFFFT algorithm have been limited to two-dimensional (2D) measurement cases. In this work, a subdimensional hybrid conversion approach is proposed as a relevant three-dimensional (3D) NFFFT method consisting of the following procedures. First, the spherical-wave information collected through 3D scanning is converted to a cylindrical waveform by applying the 2D circular NFFFT (CNFFFT) method to every vertical subplane (r-θ plane). Then, a horizontal far-field radar image on the x-y plane and an RCS pattern are extracted through direct integration of a 2D focusing operator modified to compensate for a magnitude error through distance approximation during the CNFFFT procedure. The results of a comparative study with direct integration of a 3D focusing operator are presented to show the validity and performance of the proposed method.
Estimation of CPUE and CPUA of pufferfish (Tetraodontidae) caught by the Bottom Trawl Fishery in the eastern Mediterranean Coasts
Authors: TURAN Cemal
Published: August 2022

Two indicators of pufferfish communities, catch per unit effort (CPUE) and catch per unit area (CPUA), were used with surveys of bottom trawl fishery to elucidate the level of the catch of each pufferfish species in the Mediterranean coasts of Turkey, comprising the Iskenderun Bay, Mersin Bay, and Antalya Bay. The surveys were conducted seasonally in 2019. The average rate of CPUE for Lagocephalus sceleratus, L. suezensis, L. spadiceus, and Torquigener flavimaculosus were 2.2, 0.8, 0.5, and 0.2 kg km-2, respectively that the highest CPUE values were in winter (8.0 kg km-2) for L. sceleratus and also lowest was in winter (0.08 kg km-2) for L. spadiceus. The highest and lowest CPUE values were at the depth of 20-50 m (2.7 kg km-2) for L. sceleratus and 50-80 m (0.08 kg km-2) for T. flavimaculosus, respectively. The highest CPUE values (3.5 kg km-2) were found at the sandy bottom for L. sceleratus, and the lowest one (0.01 kg km-2) was at the hardy-ground for T. flavimaculosus. The average annual CPUA of pufferfish species at the Iskenderun, Mersin, and Antalya bays was estimated as 15.6, 28.4, and 6.81 kg, respectively, with a mean value of 17.3 kg/day/boat. In multiple correspondence analysis, L. sceleratus showed a great contribution to CPUE and CPUA data. However, T. flavimaculosus revealed contribution, especially in catch numbers which were positively affected by precipitation. L. spadiceus, L. suezensis, and T. flavimaculosus were positively affected by depth, temperature, month, season, and bottom structure.

Published: August 2022

Biogenic amines are biologically active, nitrogen based, low molecular mass substances and they consider as quality and toxicity indicators of foods. The amount of biogenic amines indicates also the freshness of the food products. These compounds form during production or storage of protein rich foods under unhygienic conditions. These amines are usually formed in protein rich foods by the act of microorganisms which has decarboxylase activity under inappropriate technological processing conditions especially while fermentation processes. Cheese, yogurt, kefir are among the most consumed fermented foods. Since these products are much consumed food products, the analysis of biogenic amines in them is very important in terms of consumer health and product quality. Biogenic amines taken in high amounts are known to cause headache, nausea and more serious food poisoning. There are studies both abroad and in our country on cheese varieties where biogenic amine formation is frequently observed. However, there is no study conducted in the Hatay region, which is extremely rich in terms of cheese varieties. Within the scope of this study, biogenic amine analyzes were performed on 20 cheese samples produced and consumed in the Hatay region after they were kept in the refrigerator at 4 ºC for 30 days. Total biogenic amine concentrations were determined between 57.00–432.41 mg kg-1. The samples with the highest total biogenic amine concentrations were blue-veined cheese (432.41 mg kg-1) and moldy cheese (314.45 mg kg-1). Total biogenic amine concentrations were the lowest in aged cheddar cheese (57.00 mg kg-1) and knitted cheese (97.57 mg kg-1). All of the biogenic amines (spermidine, putrescine, cadaverine, histamine, tryptamine, tyramine, phenylethyl amine) were detected in all cheese samples examined.

Nowadays, the majority of marine debris consists of microplastic particles. For that reason, microplastic pollution in marine environments and its potential impacts on marine animals has been extensively studied. This study was developed to investigate the bioindicator potential of Pterois miles (Bennett, 1828) for the monitoring of microplastic pollution. A totally, 21 individuals were sampled from Iskenderun Bay, northeastern Mediterranean Sea on April 2022, and their gastrointestinal tracts were examined for microplastic occurrence. Mean microplastic abundance was found as 2.06±1.88 particles/individual in positive samples and 1.47±1.83 particles/individual in total samples. The microplastic detection rate was estimated as 71%. In terms of color, black (55%), blue (32%), red (10%) and brown (3%) microplastic particles were detected. Among all, the majority of the extracted particles were fiber in shape (93%) and followed by fragments (7%). The high frequency of detection and microplastic abundance estimated in this study showed that this specie could be used to monitor microplastic pollution in marine environments.

The use of wood as a building material must be designed quite rigid and strong. According to SNI 7973:2013, the corrected design value on the wooden structure components must be in accordance with the condition of wood to be used. The objective of this study is to determine the value of timber beams stability (CL) both of softwood and hardwood based on SNI 7973:2013 for construction purposes. The material in this research to be used are pine (Pinus merkusii), agathis (Agathis dammara), mahagony (Swietenia macrophylla), and red meranti (Shorea leprosula). Testing of physical properties include moisture content, specific gravity, and density, meanwhile testing of mechanical properties include flexural strength, modulus of elasticity, and ductility. Mechanical testing is carried out on a small clear specimens and full-size specimens, while the physical properties are tested only on a small clear specimens. The full-size specimens are visually sorted and the strength ratio (S) is determined prior to mechanical testing. The result of this study showed that the highest strength ratio was in meranti 55.85%, agathis 52.98%, pine 46.76%, and mahogany 46.60%. Softwood has a lower S value to more knot defects than hardwood. The slenderness ratios of agathis, pine, mahogany, and meranti wood respectively are 7.48, 7.45, 7.40 and 7.66 so that all specimens are referred to as short beams. The value of beam stability (CL) is close to 1 that indicates that the beams are stable and does not twist.
