Published: February 2024

Rice stunt disease is one of the causes of rice harvest failure. It is caused by the infection of Rice ragged stunt virus (RRSV) and Rice grassy stunt virus (RGSV) infection. Information about disease severity and the molecular characteristics of stunt viruses in Indonesia is still limited. Thus, this research aimed to determine the disease severity and the genetic diversity of rice stunt viruses in Gianyar, Bali. The research method consisted of observation of incidence and disease severity in the field and virus detection by reverse transcription-polymerase chain reaction (RT-PCR) using primers specific for RRSV and RGSV. The observation of the disease incidence and severity were performed in seven districts in Gianyar Regency, Bali, namely Blahbatuh, Gianyar, Payangan, Sukawati, Tampaksiring, Tegallalang, and Ubud. Stunt disease was found in all observation sites. High stunt disease incidence (> 44%) was found in three districts: Ubud, Tampaksiring, and Payangan, while the low disease incidence rate of <10% was found in Blahbatuh and Gianyar Districts. The highest stunt disease severity occurred in Tampaksiring District (60.82%), while the lowest severity occurred in Gianyar District (18.84%). The IR-64 and Ciherang cultivars are vulnerable to rice stunt disease infection. The highest homology of RRSV and RRGV nucleotides was found with Vietnam isolates being >98% and >97%, respectively. The phylogenetic analysis showed that Indonesian isolates of RRSV and RGSV were clustered in the same group as Vietnam isolates.

In accordance with the explanation of article 76 UU No.12 Tahun 2012 about Higher Education. In article 76 Paragraph 1 Explained that, "The Government, Local Government, and/or Universities are obliged to fulfill the rights of economically disadvantaged students to be able to complete their studies by academic regulations". As for those who were accepted, only 61,067 participants were. They are scattered in various colleges. Based on the technical guidelines for the implementation of the KIP Kuliah 2021 selection for the Education Financing Service Center of the Direktorat Jenderal Pendidikan Tinggi Kementerian Pendidikan dan Kebudayaan Republik Indonesia, several criteria must be met by prospective students. The results of the absolute requirements are then re-selected in the form of academic ability tests and interviews conducted to capture assistance so that they are right on target. Based on the number of prospective enthusiasts who register, the registration process takes a lot of time, starting from the selection process for completeness of documents, and academic potential tests, to interviews. In its implementation, choosing prospective students who are by the criteria requires more time and allocation of human resources, so this research is expected to make it easier for universities to monitor the activities of KIP Kuliah recipient students and make it easier to evaluate students on the results of the scores that have been obtained

Authors: Pratama Destra Andika , Damsi Faisal , Zarkasih M Sandy
Published: February 2024

One of the newest sources energy is the sun. To limit the usage of fossil fuels, solar power facilities that harness sunlight are beginning to be created. Currently, research on solar panels is increasingly being carried out. Because solar panels are an unlimited source of energy. And solar panels can reduce exhaust emissions from conventional vehicles by 92%. However, the performance of solar panels is strongly influenced by several factors such as sunlight intensity and ambient temperature. So that solar panels can reach the maximum power point, the Maximum power point tracking (MPPT) method is employed to maximize the performance of solar panels. In this research, an mppt system will be created using fuzzy logic control in matlab simulink. Fuzzy logic control is a method that can control the system against load changes. To analyze this fuzzy logic-based mppt system, simulations are carried out using matlab simulink. Simulink is software used to model, simulate, and analyze dynamic systems. From the simulations that have been carried out, solar panels without mppt have a duty cycle change time of 0.1 seconds while with mppt the duty cycle change is 0.7 seconds, where the duty cycle change time without mppt is faster but the operating value is unstable while power tracking with mppt the duty cycle change time is longer but the operating value is more stable.

The most important condition of ecological restoration is the identification of reference ecosystems, which function as a guide for assertive practice with which biological integrity and ecosystem structure and function can be compared. For restoration and conservation projects to be effective in the current scenario of biodiversity and ecosystem services decay worldwide, it is fundamental to understand the soil-plant interactions in each environment. In this study, we evaluated the structure and composition of the flora in 45 plots, equally distributed in three preserved areas (reference ecosystems) of Atlantic Forest in the upper Rio Doce watershed, Southeast Brazil. We also tested whether differences in species composition were influenced by edaphic factors, both in the adult tree and sapling strata. In both tree and sapling strata, Fabaceae was the species-richest family, followed by Myrtaceae, and Lauraceae. The Fabaceae family also showed the highest importance value for both strata. The soils of the riparian forests were highly heterogeneous among the studied sites. Co-inertia analyses indicated a clear edaphic-floristic gradient in both tree (RV = 0.467; p < 0.001) and sapling (RV = 0.478; p < 0.001) strata, with a connection of 46.7% and 47.8% between the edaphic and floristic matrices for trees and saplings, respectively. We identified the groups of tree and sapling strata species that were strongly associated with either nutritionally richer or poorer soils on each studied site. Understanding how ecological and life-history traits of plant species relate with edaphic factors is an important step to provide scientific-based knowledge to support policies for ecosystem recovery and restoration in the stretches of the Rio Doce watershed.
Green Marketing and Greenwashing in Poland and France, a Comparison of Consumer Reactions
Authors: Kowalik Izabela , Leyge Marine , Sikora Tomasz
Published: February 2024

Purpose

The human influence on the environment and its protection are subjects of marketing communication, and numerous regulations were issued to control the “green” messages. The popularity of such practices makes it essential to compare the reactions to green marketing and greenwashing in two European societies and to check how “green” awareness of European consumers translates into behavior.

Design/method/approach

The review of literature and decisions regulating green marketing is followed by a CAWI study of the French and Polish young consumers ecological attitudes, intentions, and behaviors. ANOVA and linear regression methods were used to analyze data.

Findings

The French young consumers are more pro-environmentally focused than Poles and display more robust skepticism toward sustainable claims. The Poles, more than the French, focus on the products' primary functions. Both groups show higher levels of spontaneous awareness of greenwashing than average consumers in those two countries. Our hypotheses about relationships of ecological attitudes with purchase intentions and behavior were supported. Surprisingly, there was a negative relation between French nationality and environmental behaviors.

Originality/Value

There is a regional market segment of European consumers from Generation Z who react similarly to green marketing claims and reject the greenwashing actions. They are highly environmentally aware, but the relationships between their eco-attitudes and behaviors, albeit significant, are weak.

Practical implications

The marketers aiming their activity at the young customer segment should not expect an immediate influence of ecological attitudes on behaviors. This market segment can instead become a powerful influencing group among their societies.
How general is managerial human capital?: Evidence from the Retention of Managers after M&As
Authors: Hirata Kenjiro , Suzuki Ayako , Takii Katsuya
Published: February 2024

This paper investigates the transferability of managerial human capital by examining how managers’ tenures in target firms influence their probability of retention as board members after mergers or acquisitions in Japanese firms. It develops a general equilibrium model that distinguishes several hypotheses on managerial human capital based on the coefficients of tenure on separation, given several data limitations. In particular, the paper provides a novel method to correct for selection biases by utilizing the timing of selection in a selected sample, which does not require a random sample from the population. Our results suggest that Japanese firms value both target firm-specific and general human capital after M&As and that experience as an employee increases firm-specific skills, but at the expense of the accumulation of general skills. However, managerial experience does not have this effect.

Authors: Yadav Ajay , Kumar Ajay , Prakash Amit
Published: February 2024

The all-optical switching phenomena in the non-linear directional coupler using cross-phase modulation (XPM) effect have been proposed. It is designed to generate an all-optical XOR functionality, considering the XOR logic gates as a basic module the design and analysis of an efficient all-optical 4-bit binary to gray code converter and 4-bit even parity checker circuit is proposed. The design methodology includes the switching of a weak continuous-wave (CW) signal, which is controlled by the combination of two controlled pump signals. In this paper, mathematical analysis of the coupled mode theory associated with optical directional couplers has been discussed. The switching characteristics of XPM effect based All-optical directional couplers have been examined for appropriate values of the controlled pump signals. Appropriate values of extinction ratio and corresponding controlled pump signal levels are investigated for an efficient generation of XOR logic gates. Further, the detailed analysis of layout generation and design aspects of All-optical 4-bit binary to gray code converter and 4-bit even parity checker circuits have been carried out. The proposed methodology is verified by the appropriate simulation results, which include the transmittivity, extinction ratio (Xratio) curve variation and dynamic time domain plot associated with proposed units.

This study presents different approaches to increase the sensing area of NiO based semiconducting metal oxide gas sensors. Micro- and nanopatterned laser induced periodic surface structures (LIPSS) are generated on silicon and Si/SiO2 substrates. The surface morphologies of the fabricated samples are examined by FE SEM. We select the silicon samples with an intermediate Si3N4 layer due to its superior isolation quality over the thermal oxide for evaluating the hydrogen and acetone sensitivity of a NiO based test sensor.
Linear block code with locality and availability inspired by tetrahedron
Authors: Farkaš Peter
Published: February 2024

The primary application of codes with locality and availability in distributed storage is for data recovery in case that data are lost on some damaged servers. Locality enables the recovery of lost data by contacting only a restricted number of remaining servers. Availability means that more than one subset of servers providing locality is available for data recovery for each server. The secondary application of these codes in distributed storage is to allow access to hot data in times of high demand. In this paper it is shown that the binary linear [14, 4, 7] code has locality 2 and availability 6 and it can be interpreted as a three-dimensional graph obtained from a [7, 3, 4] Simplex code. It is achieving upper bounds on basic parameters for codes with all-symbols locality and availability. This code can be a building element of more complex codes with scalability inspired by three-dimensional structures. The availability spectrum is introduced as a tool for analyzing codes with locality and availability.

Published: February 2024

Introduction

Herpesviruses are common agents in animals of the aquatic environment. They infect many species of fish but only lead to disease in one or two species. Nevertheless, infected fish without clinical symptoms can actively transfer infectious agents to disease-susceptible species. The aim of the study was to identify and prove the natural presence of different herpesviruses.

Material and Methods

Koi, Nile tilapia, grass carp, goldfish and crucian carp were infected with a herpesvirus isolate 99% identical to goldfish herpesvirus (GHV) or cyprinid herpesvirus 2 (CyHV-2) obtained from crucian carp. Before and after infection, samples were collected non-lethally at different time points from all five fish species to identify and evaluate the replication of viruses naturally infecting the fish as well as the CyHV-2 experimentally infecting them. Gill swabs and separated leukocytes were subjected to PCR and the results compared.

Results

These samples yielded DNA of koi herpesvirus (KHV, also referred to as CyHV-3), GHV and a new herpesvirus. While Asian-lineage CyHV-3 DNA was detected in samples from crucian carp and goldfish, CyHV-2 DNA was found in samples from koi and tilapia. A new, hitherto unknown herpesvirus was identified in samples from grass carp, and was confirmed by nested PCR and sequence analysis. The survival rates were 5% for grass carp, 30% for tilapia, 55% for crucian carp, 70% for koi and 100% for goldfish at 20 days post infection. Evolutionary analyses were conducted and five clusters were visible: CyHV-1 (carp pox virus), CyHV-2 with sequences from koi and tilapia, CyHV-3 with sequences from crucian carp and goldfish, probable CyHV-4 from sichel and a newly discovered herpesvirus – CyHV-5 – from grass carp.

Conclusion

The results obtained with the molecular tools as well as from the animal experiment demonstrated the pluripotency of aquatic herpesviruses to infect different fish species with and without visible clinical signs or mortality.
A Practical Solution to Reduce Interference from Led Lights
Authors: Kallunki J.
Published: February 2024

The study explores the detection of a harmful, wide-band interference signal, whose origin is a traditional desk LED (light-emitting diode) lamp. The interference signal was noticed on the sensitive solar spectrometer observing system, which was operating at a frequency range between 100 and 300 MHz. The interference signal was so strong and wide-band that it destroyed totally the solar observations. The study introduces two practical EMI (Electromagnetic Interference) reducing methods: ferrite cores and shielding (shielding effectiveness, S.E.). Their theoretical background is presented, and, in addition, these methods are tested in practice. The measurements and tests showed that even simple ferrite core was a very effective method to reduce interference effects. It is important that a suitable setup will be found: a single ferrite core cannot solve a whole problem. This interference problem is very demonstrative and it can be used in educational purposes at an undergraduate level at Metropolia University of Applied Sciences, Finland. This study reveals the fact that standard lamps, which are on the market, do not necessarily follow good EMC (Electromagnetic Compatibility) practices.

Analysis of the frequency and type of CT examinations performed in Poland in 2022
Authors: Pankowski Piotr , Wrzesień Małgorzata
Published: February 2024

Introduction: Computed tomography (CT) is one of the most widely used diagnostic procedures in modern medicine. Despite many technical improvements, CT still exposes patients to significantly higher doses of radiation than other methods of diagnostic imaging. The presented analysis of the number of CT scans performed in Poland in 2022 aims to designate priorities in the process of optimising radiation protection and makes it possible to identify those examinations and patient groups for which action is particularly justified.

Material and methods: The data presented is based on an analysis of the National Health Fund (NHF) database of medical services reimbursed in 2022. According to the NHF data, approximately 5.1 million CT examinations were performed. The coding of reimbursed medical procedures used by the NHF in 2022 included 45 different CT procedures.

Results: The highest ratio of the number of examinations performed to the number of patients was found in the age group 59-75 years (average 1.35). This ratio varied according to examination type and was closest to 1 for spine and extremities examinations (between 1.1 and 1.2 on average). Irrespective of patients’ age and type of examination, the proportion of female and male patients fluctuates around 50%. Approximately 82% of head and neck examinations are single-phase CTs. Examinations with two or more phases account for about 17% and less than 1%, respectively.

Conclusions: Over the past 10 years, both the number of CT scanners and the number of annually performed scans have doubled. Relative to the population size, this is a rate of about 22 scanners per one million people, an average level for European countries, ranging from a maximum of around 37 for Italy and Germany to around 20 for France, Spain, and Romania, according to Eurostat data.

The rearing of children and young people within one of the Swedish horse riding organizations.
The purpose of this article is to analyze the importance and meaning of education within one of the Swedish horse riding organizations – Ridfrämjandet. The organization was formed in 1948, and shortly after its establishment it is clear that it attracted especially young people and children. Ridfrämjandet, as many other sports associations, achieved governmental subsidies for their youth activities and a large amount of their work was devoted to courses. The sociologist Tomas Peterson has used two concepts to characterize the educational strivings within the sports associations: education for competition and education for citizenship. Furthermore he has demonstrated that the courses arranged by the Swedish Football Association soon after their introduction developed competitive characteristics. By contrast, the courses arranged by Ridfrämjandet focused on citizenship education. In order to characterize the educational strivings in Ridfrämjandet, another concept has to be used as well – education for caretaking. It is possible that the caretaking characteristics in the equestrian organization can be connected to the process of feminization.

Objective: The aim of this study was to evaluate the behavior of cupuaçu tree (Theobroma grandiflorum) seedlings as a function of agro-industrial waste.
 
Method: The influence of agro-industrial waste on the development of cupuaçuzeiro seedlings was evaluated. Treatments included different proportions of organic waste (açaí ash, dendê compost and cattle manure) in proportions of 5%, 10%, 15% and 20% in relation to 3 kg of soil. Finally, morphological and physiological variables were determined.
 
Result and Conclusion: The experimental data was analyzed using analysis of variance. Significant means were then compared using the Tukey test, with a significance level of 5%. From the results obtained, it was observed that one of the agro-industrial residues has the potential to act as an alternative substrate in the production of Theobroma grandiflorum seedlings.
 
Researchimplications: The Theobroma grandiflorum species stands out as being extremely important, since its products and by-products are widely accepted in domestic and foreign markets, as well as contributing to Agroforestry Systems. In addition, there is a need to study alternative substrates, especially those generated on a large scale, considering the need to promote proper disposal with sustainable use.
 
Originality/value: In the current scenario, with regard to the destination and final disposal of solid waste, there is a need to look for sustainable alternatives aimed at reusing this waste, especially in agriculture.
Der Personzentrierte Ansatz in der Behindertenarbeit
Authors: Zinschitz Elisabeth
Published: February 2024

Vor neun Jahren wurde ich zum ersten Mal mit dem Thema Behinderung konfrontiert. Damals hatte ich keine Ahnung, was da auf mich zukam, und der Personzentrierte Ansatz war mir noch gänzlich unbekannt.
Als ich begann, in der Frühförderung und Familienbegleitung mit Kleinkindern mit verschiedenen Behinderungen zu arbeiten, dachte ich, ich müßte mit ihnen viel üben, damit sie ihre Behinderungen möglichst viel kompensieren könnten. Sie sollten von mir lernen zu greifen, zu schauen, zu hören, zu sprechen. Inzwischen habe ich von ihnen gelernt zu begreifen, genau zu schauen, genau hinzuhören und ihre Sprache zu sprechen. Während derselben Zeit lernte ich den Personzentrierten Ansatz kennen, der mir in diesem Prozeß äußerst hilfreich war.
Ein sehr wichtiger Schwerpunkt in meiner Arbeit ist die Lebensqualität, wobei Integration und Autonomie eine wichtige Rolle spielen. Um einem behinderten Menschen dabei zu helfen, das zu erreichen, ob in der Psychotherapie oder in einem anderen Rahmen, ist es m.E. erforderlich, einerseits zu verstehen, wie seine Behinderung seine seelische Entwicklung beeinflußt hat, und andererseits, diesem Menschen als ganzer Person zu begegnen und nicht den Fokus auf die Behinderung zu legen. Nur so kann ich seinen inneren Bezugsrahmen verstehen und ihm helfen, das eigene Erleben ernstzunehmen, die eigenen Grenzen wahrzunehmen und im jeweils möglichen Rahmen selbstbestimmend zu leben.
Personzentrierte und experientielle Psychotherapie in einem kulturellen Übergangszeitalter
Authors: O’Hara Maureen
Published: February 2024

Der Beitrag ist die deutsche Übersetzung eines Vortrages, den Maureen O'Hara, eine der bekanntesten Persönlichkeiten der zeitgenössischen Humanistischen Psychologie, im Rahmen des PCA-Symposiums in Wien gehalten hatte. Ausgehend von einer historischen Perspektive versucht sie eine Einschätzung der Zukunft der Personzentrierten Psychotherapie in einem "kulturellen Übergangszeitalter". Aus einem postmodernen Blickwinkel unterscheidet sie eine prämodernistische, eine moderne und eine postmoderne Psyche. Aus dieser Sicht war die frühe personzentrierte Psychotherapie noch stark ein Produkt eines modernistischen Weltbildes. Die postmoderne Krise der Gesellschaft stellt jedoch eine Chance für diese therapeutische Richtung dar, weil sie in diesem Kontext ihre emanzipatorische Kraft und ihr Menschenbild neu entfalten kann. Der personzentrierte Ansatz könnte sich so zu einer personzentrierten Psychologie der Postmoderne entwickeln.
Diesseits und jenseits von Begegnung. Zur Integration psychotherapeutischer Schulen aus personzentrierter Sicht
Authors: Slunecko Thomas
Published: February 2024

Der Artikel versucht zu entwickeln, wie sich Integrationsbestrebungen innerhalb der Psychotherapie durch den Rückgriff auf zentrale Elemente des personzentrierter Ansatzes, insbesondere auf das darin formulierten Verständnis von Begegnung, gestalten lassen; damit werden Erkenntnis - und Wissensansprüche formulierbar, die der interpersonalen Natur der psychotherapeutischen Praxis angemessener sind als solche, die zum Zwecke einer vermeintlichen wissenschaftlichen Aufwertung aus anderen Fächern importiert werden. Vor allem wird auch ein produktiver Umgang mit der Schulenvielfalt möglich: das Bestehenlassen und im Dialog erst wechselweise Verständlichwerden von unterschiedlichen Positionen läßt sich als eine konstitutive Qualität der Gesamtdisziplin Psychotherapie verstehen, die sie sich gegenüber vereinheitlichenden und reduktionistischen Ansprüchen unbedingt bewahren sollte. Für den personenzentrierten Ansatz gibt der Dialog mit den "anderen" Gelegenheit, sich bestimmter kultureller und metaphysischer Erbstücke bewußt zu werden, die in der weiteren Entwicklung problematisch werden könnten.

Person als Schaltstelle von Veränderungsprozessen Eine Brille der mehrdimensionalen Betrachtung
Authors: Mitterhuber Beatrix
Published: February 2024

Ist Veränderung und Entwicklung einer Institution denkbar ohne dass die Person sich für Veränderungen und Entwicklung öffnet? Organisationen sind nicht aus sich selbst entstanden, sondern sind von den steuernden Eingriffen von Personen abhängig. Dieser Frage und den Anforderungen an das berufliche und persönliche Selbstkonzept von Personen und dem Selbstverständnis von Organisationen soll in diesem kurzen Artikel nachgegangen werden.Das Gelingen von Veränderungsprozessen ist von der Bereitschaft und Fähigkeit von Personen, flexibel auf Herausforderungen zu reagieren, abhängig. Ebenso ist die Bewältigung dieser von der ausreichenden Berücksichtigung und der Bereitstellung von Ressourcen durch die Organisation in großem Maße bedingt. Die Ausgewogenheit zwischen Stabilisierungstendenzen und Änderungstendenzen sollen auf allen strukturellen Ebenen in einem ausgewogenen Verhältnis stehen, um eine entsprechende Selbstkonzepterweiterung zu ermöglichen und einen adäquaten Umgang mit den Anforderungen zu entwickeln.

Sugarcane bagasse has potential to be used as one of the renewable energy resources. The present work is dealt with thermal characterization of sugarcane bagasse briquettes through thermogravimetry method. The briquette samples are cylinder of 40 mm in diameter and 20 mm long. Both non-carbonized and carbonized briquettes are considered in this work. The samples comprise two different densities, i.e. 1.3 g/cm3 and 2.3 g/cm3. The samples are heated in an inert and non-isothermal atmosphere with heating rates of 5oC/min and 15oC/min. The TG curves exhibit three phases of thermal decomposition. The decomposition of the samples with higher heating rate and higher density shifts to higher temperature. The decomposition of the carbonized samples also shift to higher temperature, but to a lesser degree. The initial degradation temperature ranges from 186oC to 273oC, while the final degradation temperature ranges from 328oC to 432oC. The temperature at which the rate of decomposition is amximum ranges from 232oC to 303oC. At higher heating rate, the degradation rate shifts to lower temperatures
Roll Maneuverability of Transonic High-Aspect-Ratio-Wing Aircraft with Flared Folding Wingtips
Authors: Sanghi Divya , Cesnik Carlos E. S. , Riso Cristina
Published: February 2024

This paper investigates the roll maneuvers of a very flexible, transonic high-aspect-ratio-wing aircraft with flared folding wingtips, representing a potential future commercial transport configuration. The computational study leverages a fully coupled nonlinear aeroelastic-flight dynamics framework for simulating roll maneuvers commanded by deflecting control surfaces inboard or outboard of the flared folding wingtip hinge. Releasing the flared folding wingtips during flight makes the aircraft roll faster only when deflecting outboard-of-hinge leading-edge control surfaces. However, the achieved roll angles and rates are much lower than the ones obtained by deflecting inboard-of-hinge trailing-edge control surfaces, whose roll control effectiveness is not impacted or even degrades when releasing the flared folding wingtips. These trends are explained by analyzing the role of sweep-induced washout effects in the very flexible, transonic high-aspect-ratio wing, revealing physical mechanisms not identified in previous studies on straight or swept wings with moderate flexibility. Higher wing out-of-plane bending stiffness increases the effectiveness of flared folding wingtips in enhancing roll maneuvers at low dynamic pressure but plays a slight role at high dynamic pressure. This study highlights the need to consider the impact of washout effects for different flight conditions and levels of wing flexibility when assessing the ability of flared folding wingtips to enhance the roll maneuverability of transonic high-aspect-ratio-wing aircraft.
Aerodynamic Exergy-Based Analysis and Optimization of the Generic Hypersonic Vehicle Using FUN3D
Authors: Novotny Neal L. , Rumpfkeil Markus P. , Camberos Jose A. , Nielsen Eric J. , Diskin Boris
Published: February 2024

The development of future novel aircraft concepts requires a holistic approach to vehicle design, analysis, and optimization. Aircraft designers can no longer consider components individually as systems become more interconnected and multidisciplinary. Hence, a new approach to aircraft design and a new way to measure the performance of aircraft are needed. A novel approach to aircraft design is the use of exergy methods that can evaluate typically disparate systems using a universal measure of performance mapped to global system performance. This paper introduces a new functional and its adjoint gradient in FUN3D to determine aerodynamic exergy destruction rates. The functional is verified using the Oswatitsch relationship by comparing it to native, surface-based drag coefficients. The adjoint gradient is verified using the FUN3D native complex step method, and discrete agreement is demonstrated for flowfields and geometric derivatives. The new functional is then used for aerodynamic exergy-based analysis and optimization of the generic hypersonic vehicle. An inverse design problem is conducted first to verify the design optimization framework. Finally, a planform and airfoil aerodynamic inviscid exergy optimization of the GHV is conducted, improving exergy destruction rates by 7.1% while making substantial improvements to the cruise trim characteristics of the vehicle.
Circular-Feature-Based Pose Estimation of Noncooperative Satellite Using Time-of-Flight Sensor
Authors: Mu Jinzhen , Li Shuang , Xin Ming
Published: February 2024

This paper develops an end-to-end circular-feature-based pose estimation using the time-of-flight (TOF) camera for capturing serviced satellite. First, the docking ring is chosen as the recognized object for pose measurement. Second, a new ellipse detection method is proposed to detect the docking ring. Third, the circular feature is used to estimate the six-degrees-of-freedom pose with the aid of a reflective block. Combined with the range at each pixel location from TOF, the pose duality can be eliminated, and the roll angle is recovered through the geometric constraint. Ground physical experiments validate the effectiveness and efficiency of the proposed method. The on-orbit application demonstrates that the proposed algorithm can accurately and robustly estimate the relative pose of the noncooperative satellite, providing reliable navigation information for the chaser spacecraft with the relative pose estimation errors less than 2 deg and 5 cm.
Nonlinear Estimators for Hypersonic Heat Flux Reconstruction
Authors: Nguyen Nhat M. , Ruda Mathew L. , Massa Luca
Published: February 2024

A novel class of nonlinear estimators that minimizes the projection of the error on a multiresolution basis is developed to improve the accuracy and efficiency of the multidimensional reconstruction of the heat flux from discrete temperature sensors in nonplanar hypersonic boundary layers. This approach uses the local temperature time derivative as the pre-estimator of the heat flux estimation risk in the inverse heat conduction problem. This new approach leads to improved results both in terms of computational efficiency and signal-to-noise ratio when compared to both regularization of the linear response operator and filtering of the temperature measurements. The approach is verified against an analytical verification test case, which shows significant accuracy improvement compared to optimal linear estimators and L2 regularization. It is then applied to experimental data to resolve the heat flux from noisy temperature data collected using fast-response sensors in the Virginia Tech hypersonic wind tunnel at Mach 6. The heat flux agrees very well with the Fay–Riddell approximation. Moreover, the heat transfer coefficient variation over the surface of the test is consistent with computational fluid dynamics simulations of the Reynolds-averaged Navier–Stokes equations.
Use of Nutraceuticals in Psychiatry

Published: February 2024

The term “nutraceutical” refers to a food or part of a food providing health or medical benefits that include prevention and treatment of a disease. It reinforces the concept of health in everyday diet as a part of nourishment and serves to functionalize food. Archaeological evidence shows that people began using plants as medicine some 60,000 years ago. Nutraceuticals are said to take part in the signal transduction pathways, maintenance of mitochondrial integrity, gene expression, and to have antioxidant effects. There are a number of nutraceuticals currently being used in the treatment of psychiatric disorders, with positive results. However, they are not patent-protected and not government-sanctioned; thus, there is a lack of regulation on their production. Nevertheless, the integration of nutraceuticals into psychiatric care represents a promising avenue for enhancing mental health treatment.
Thyroid nodule diagnosis: A comparative analysis of ultrasonography and fine-needle aspiration cytology
Authors: Nassar Omar Hassan
Published: February 2024

Objectives:

This paper aimed to investigate the association between Ultrasonography (USG) results and fine-needle aspiration cytology (FNAC) in the diagnosis of thyroid nodules (TNs) in private and public hospitals in Yemen. In addition, it aimed to determine the sensitivity, specificity of USG and FNAC in diagnosing thyroid nodules (TNs).

Materials and Methods:

The study utilized a retrospective comparative study design, analyzing medical records of patients diagnosed with TNs between June 01, 2022 and May 01, 2023, in four private and public hospitals in Yemen. USG and FNAC reports, along with demographic data were collected. The author categorized the USG findings based on the American Thyroid Association guidelines, while FNAC results were classified according to the Bethesda reporting system for thyroid cytopathology.

Results:

The study included 94 diverse participants with TNs. The average age was 39.96 years, with a majority of female participants (85.1%). The distribution of nodules revealed varying consistencies, sizes, and shapes. The association between USG and FNAC diagnoses showed a significant relationship (χ2 = 34.914, P < 0.001), with a high proportion of benign cases in both USG and FNAC results. Validity analysis demonstrated a sensitivity of 88.68% and a specificity of 70.73% for USG in diagnosing thyroid carcinoma. The positive predictive value was 79.66%, and the negative predictive value was 82.86%. The overall accuracy of USG compared to FNAC was 80.85%.

Conclusion:

This study shows USG’s potential as a diagnostic tool for TNs in Yemen. Insights improve understanding of TN diagnosis in Yemen’s healthcare settings.

Traumatic spondylolisthesis of the lumbosacral junction (SPL) is a spinal injury rarely seen in current practice. Few cases are reported in the literature. It arises from complex trauma of high-energy mechanisms. We discussed the case of a young patient. He is 24 years old without notable pathological history victim of a traffic road accident. Clinically, he has no sensory or motor deficit, it is a spinal trauma classified American spinal injury association E (ASIA E) with severe back pain. A whole-body CT scan performed on admission showed a grade 2 L5–S1 SPL. A lumbar MRI revealed a tear of the disc at L5–S1. We performed a laminectomy to decompress the dural sheath and cauda equina roots with transforaminal lumbar interbody fusion. A postoperative CT scan showed the reduction of the spondylolisthesis. Two months later, the patient resumed walking. Surgery is the gold standard for the management of traumatic SPL. The aim of surgery is to achieve neural structure decompression and obtain stability with fusion.

Finansal raporlarda yapılan hata hile ve usulsüzlükler yıllardır literatüre araştırma konusu olmuş, konuyla ilgili farklı ülkelerde farklı çalışmalar yapılmıştır. Bu çalışmanın amacı, belli bir ülkede elde edilen modellerin diğer ülkeler için de geçerli olup olmayacağını araştıran bir çalışma ortaya koymaktır. Bu amaçla, SPK bültenleri 2009-2019 yılları için incelenmiş, taranan 520 bültenden 45 firma hakkında hata, hile ve usulsüzlük tespit edilmiştir. Bu firmalar için aynı faaliyet alanında ve aktif büyüklüğü birbirine yakın 108 firma ise kontrol değişkeni olarak seçilmiştir. Oluşturulan modelde açıklayıcı değişken sayısı 22 olup bu değişkenlerden 8’i Beneish (1999) tarafından ABD’de yapılan çalışmalarda ortaya konan modelin açıklayıcı değişkenleridir.

Analiz sonucu modellerde manipülasyon yapan firma ile eşit sayıda kontrol değişkenli(eşlemeli) modelin başarısı, manipülasyon yapan firmalara karşılık daha fazla sayıda kontrol değişkenli(eşlemesiz) modelin ayrıştırma gücünden daha düşük kalmıştır. Ayrıca eğitim seti ve test veri seçiminde rastgele seçim yapmak, baz yıl (uygulamada 2015 seçilmiştir) kullanarak model oluşturmaya nazaran daha çok açıklayıcı değişken ve daha güçlü ayrıştırma yapan model kurmaya katı sağlamaktadır. Ayrıca oluşturulan her bir modelin performansı, Beneish M-skoru’nun manipülasyon yapan/yapmayan firmaları ayrıştırma yeteneğinden daha yüksek olduğu görülmektedir. Sonuçta manipülasyon tespitinde her ülke için geçerli bir model oluşturmanın mümkün olmadığı görülmüştür.
