Authors: Wang Wei , Yang Weizhen , Li Maozhen , Zhang Zipeng , Du Wenbin
Published: July 2023

Apple is an important cash crop in China, and the prediction of its freshness can effectively reduce its storage risk and avoid economic loss. The change in the concentration of odor information such as ethylene, carbon dioxide, and ethanol emitted during apple storage is an important feature to characterize the freshness of apples. In order to accurately predict the freshness level of apples, an electronic nose system based on a gas sensor array and wireless transmission module is designed, and a neural network prediction model using an improved Sparrow Search Algorithm (SSA) based on chaotic sequence (Tent) to optimize Back Propagation (BP) is proposed. The odor information emitted by apples is studied to complete an apple freshness prediction. Furthermore, by fitting the relationship between the prediction coefficient and the input vector, the accuracy benchmark of the prediction model is set, which further improves the prediction accuracy of apple odor information. Compared with the traditional prediction method, the system has the characteristics of simple operation, low cost, reliable results, mobile portability, and it avoids the damage to apples in the process of freshness prediction to realize non-destructive testing.

Introduction. The protection of the reproductive health of the younger generation is one of the most significant problems due to the steady growth of various gynecological diseases, including those that are asymptomatic, which has a significant impact on the reproductive potential of the young population. Purpose to reveal the prevalence of gynecological pathologies among girls in the Moscow region. Material and methods. We have analyzed the main gynecologic diseases among patients aged 0–17 years according to the results of preventive examinations and data of visits to the pediatric gynecologist in the outpatient clinic for the year 2021. Results. Recent analytical data on the prevalence of gynecological morbidity of girls and young women in Moscow region showed that in children aged 0–4 years and 5–9 years, inflammatory diseases of the vulva and vagina (vulvitis) and labia minora adhesions predominate. In patients aged 10–14 years gynecological pathology is represented by various menstrual cycle disorders, dysmenorrhea, inflammatory diseases of the vulva and vagina (vulvitis), non-inflammatory ovarian diseases (follicular cysts and cysts of the yellow body of the ovary) and also mammary gland diseases. The predominant gynecological pathology in girls aged 15–17 is inflammatory diseases of the vulva and vagina, menstrual disorders, non-inflammatory ovarian diseases (follicular cysts, cysts of the corpus luteum), fallopian tubes and the vagina, breast diseases, and sexually transmitted infections are also frequent. Conclusion. We can talk about the general trends in the prevalence of gynecological morbidity among girls and young women in Moscow region and in the whole territory of the Russian Federation. Following the order of the Russian Ministry of Health of 20.10.2020 № 1130n «On approval of the Order of medical care in the profile „obstetrics and gynecology“», we can achieve a reduction in gynecological morbidity among girls and young girls in the Moscow region by improving specialized gynecological care

Ovarian tumors are an important and urgent problem of modern gynecology. This is due to the difficulties in diagnosing neoplasms due to the absence of characteristic complaints and frequent asymptomatic course. Pediatric surgeons, pediatric gynecologists should conduct differential diagnostics between ovarian tumors and tumors of the abdominal cavity and retroperitoneal space in order to timely diagnose and treat neoplasms and prevent possible medical error. The article presents an indicative clinical case of the occurrence of giant mucinous ovarian cystadenoma in a teenage girl requiring differential diagnosis with formations of a different localization. Patient F., 16 years old, was admitted to the hospital in the direction of one of the regions of the Russian Federation. The reason for the patient's treatment to a gynecologist at the place of residence was pain in the lower abdomen for a month and an increase in the size of the abdomen. The patient was sent to the hospital to clarify the diagnosis and further treatment. Radical surgical treatment was performed: removal of the cyst of the left ovary using video endoscopic technologies

The European Union is based on economic, social and territorial unity, as well as on balanced economic growth and convergence. As the European Foundation for the Improvement of Living and Working Conditions points out: "convergence trends between member states have been achieved in recent decades in both economic and social dimensions". After adoption of the "Europe 2020" strategy by the European Council in 2010, as well as of the European Green Deal, great attention have been paid to environmental problems in the development of the member countries. These strategies emphasize the need for joint actions by member states in the direction of sustainable development. Today, the governments of countries, politicians, scientists, public organizations and other interested parties are searching for effective ways of economic growth, taking into account the listed planetary and ecological limits, as well as its ecological consequences, which actualizes the teaching of ecological and economic growth. The purpose of the article is to define the conceptual foundations of ecological and economic convergence. The article examines a set of countries (regions) that are members of the so-called "convergence club". The indicator of CO2 emissions in these countries is highlighted, which reflects only a part of the cumulative consequences that are the result of extensive energy consumption. Ecological and economic convergence is analyzed, namely the analysis of foreign sources. The author proposed the ways to solve the issues of absolute and relative unevenness of development, as well as their comparison. It was confirmed that if a country (region) with a lower level of socio-economic development tries to get closer to the corresponding level of a leading country (region), then the standard of living in the first one will increase, and the gap between countries (regions) will also decrease. And corresponding growth in real income per capita will take place in the "lagging" countries.

Contrastive Analysis of English and Pashto Adjectives
Authors: Raziq Safi Abdul , Pamir Ehsanullah , Haqpararst Arifullah
Published: July 2023

Language is a systematic means of communication that employs sound or conventional symbols. Using a foreign language can be problematic when attempting to communicate or translate written or spoken language from one's native language due to structural differences between languages. Among the most widely spoken languages in the world, English is understood by approximately half of the global population, though it is neither an official nor a second language in our country. Nonetheless, due to its significance, it is often taught as a foreign language at schools, institutes, and universities. As previously mentioned, Pashto, our language, shares both structural similarities and differences with English, which can pose challenges for learners. To address these difficulties in learning English, this paper presents a contrastive analysis of English and Pashto adjectives, examining the similarities and differences between them. The study employs a descriptive and contrastive methodology.

Published: July 2023

Nutrition is essential for the survival of individuals. The body needs to get the nutrients it needs for growth and development. Especially in recent times, body shape and physical appearance have become important with the uniform acceptance of body perception. Adolescent and young individuals were selected as the target group in this study. Eating disorders have emerged as a result. These disorders negatively affect a person's mental and social behavior. Depression is the most common mental disorder that reduces a person's energy, self-confidence, and quality of life. Some of the depressed individuals have less eating behavior and some have more eating behavior. Research shows that people with eating disorders are more likely to suffer from depression. Nutrition can be used in the prevention and treatment of behavioral health problems.

Avian Models of the Neurobiology of Anxiety: A Systematic Review
Authors: A Isa Samya , Haq Ayman , M Husain Mustafa
Published: July 2023

Objective: Anxiety is partly driven by changes in neuroendocrine signaling, which continues to be an area of study. Birds are a useful model to study anxiety disorders due to their unique behaviors and social makeup, leading to several observable behaviors indicative of anxiety. Methods: Using PRISMA guidelines, a systematic review of studies published from January 2000 to August 2022 in PubMed, PsycINFO and MedLine was conducted. Inclusion criteria included animal studies utilizing an avian model, examining the relationship between a neuroendocrine biomarker and behavioral displays of anxiety. Exclusion criteria included review articles, editorials, studies where anxiolytic drugs were used and studies where anxiety was not the primary studied behavior. Results: 376 articles were screened. 10 papers met the review criteria. Dopamine, serotonin and glycogen synthase kinase 3β (GSK-3β) were found to be inversely related to anxiety levels. Ghrelin and γ-Aminobutyric acid type A (GABAa) were directly correlated with anxiety levels. Corticosterone correlated in a bidirectional manner depending on when a stress was applied, however, lower levels at baseline were more predictive of less anxious birds. Pituitary adenylate cyclase was shown to increase anxiety but was also time-dependent. Arginine vaso-peptide was found to reduce anxiety, but was also context-dependent. Vasointestinal Peptide had no relation to anxiety. Conclusion: Birds display similar chemical responses to humans when anxious, and due to anxiety-related behaviors unique to birds, allow for an additional approach to the investigation of different neuroendocrine markers that are not always strongly considered when studying the neurobiology of anxiety in humans.
Strategy for Climate Crisis: Introducing Innovative System for CO2 Fixation and Storage
Authors: Sorimachi Kenji , Tsukada Toshinori , Kobayashi Wataru , Gabbar Hossam
Published: July 2023

The so-called Paris Agreement was reached at the United Nations Climate Change Conference (COP20) in 2015. This agreement was based on the requirement to keep the increase in the mean global temperature below 2°C relative to the temperature prior to the industrial revolution, and preferably less than 1.5°C. At present, this goal is challenging based solely on the development of carbon-neutral energy systems. The concept of the carbon-neutral society by 2050 seems to be far too late. Herein, we propose an innovative system based on simple chemical reactions using NaOH and CaCl2 via the electrolysis of NaCl or seawater. The generated H2 from the electrolysis of NaCl can be used as a clean energy source for fuel batteries, supplying electricity for the operation of the system. When other renewable energy sources power the system, H2 can be generated as a clean energy alternative. Furthermore, this system produces stable and harmless CaCO3 as a final product, along with NaCl, which can be reused as an electrolysis starting material. The proposed system provides a safe and inexpensive approach for simultaneous CO2 fixation and storage.
Dampak Gangguan Beban Lebih Terhadap Overload Shedding Gardu Induk 150kV Sukolilo Surabaya
Authors: Akbar Firhan , Wrahatnolo Tri
Published: July 2023

Gangguan beban lebih dapat terjadi pada jaringan distribusi yang berdampak pada pemadaman listrik konsumen. Tujuan studi ini adalah untuk menganalisis akibat pengaruh gangguan beban lebih terhadap overload shedding pada sebuah gardu induk. Pembebanan transformator gardu induk 150kV Sukolilo telah melebihi 50%, maka dari itu ketika  salah satu transformator terjadi gangguan maka akan membuat pembebanan transformator yang lain meningkat. Penelitian dampak gangguan beban lebih terhadap Overload Shedding pada gardu induk 150kV Sukolilo ini menggunakan metode aliran daya dan kontingensi menggunakan ETAP 19.0. Terdapat 3 kondisi  simulasi kontingensi yang dilakukan, yaitu 1 kondisi penghantar mengalami trip dan 2 kondisi transformator mengalami trip. Simulasi gangguan beban lebih yang terjadi pada kontingensi ke 1 hingga 3 mengakibatkan dampak pada sistem yang menyebabkan overload shedding harus bekerja. Pada kontingensi 1 dan 3 menyebabkan overload shedding tahap 1 bekerja sehingga memadamkan beban sebesar 18,7 MW, namun pada kontingensi ke 2 menyebakan hingga overload shedding tahap 2 memadamkan total beban sebesar 54,5 MW. Tahapan pelepasan beban pada gardu induk 150kV Sukolilo  telah sesuai standar IEEE Std C37 106-2003  yaitu maksimal pelepasan beban pada tahap pertama yakni 10% setara 38,56 MW  dan tahap kedua 15% setara 57 MW. Hasil simulasi overload shedding ini dapat mengurangi resiko pemadaman yang bekelanjutan.Overload fault can occur in the distribution network, resulting in consumer power outages. The purpose of this study is to analyse the effect of a fault on the overload of a substation circuit. Transformer loading of 150kV Sukolilo substation has exceeded 50%, thus if a fault occurs in one of the transformers it will make the loading of other transformers increase. This research on the impact of overload faults on Overload Shedding at the 150kV Sukolilo substation uses the power flow and contingency method using ETAP 19.0. There are 3 contingency simulation conditions carried out, namely 1 condition of the conductor experiencing a trip and 2 conditions of the transformer experiencing a trip. Simulation of overload faults that occur in contingencies 1 to 3 results in an impact on the system that causes overload shedding to work. In contingency 1 and 3 caused overload shedding stage 1 to work so that it extinguished a load of 18.7 MW, but in contingency 2 caused overload shedding stage 2 to extinguish a total load of 54.5 MW. The stages of load shedding at the 150kV Sukolilo substation are in accordance with IEEE Std C37 106-2003 standards, namely the maximum load shedding in the first stage is 10% equivalent to 38.56 MW and the second stage is 15% equivalent to 57 MW. The results of this overload shedding simulation can reduce the risk of continuous blackouts.

We describe three new species ofMuricea: Muricea ambaraesp. nov.andMuricea cacaosp. nov., from rocky reefs on the central and the northern Gulf of California and the Pacific coast of Baja California Sur, andMuricea molinaisp. nov., from the Pacific coast of Baja California Sur.Muricea ambaraesp. nov.andM. cacaosp. nov.are taxonomically allied to the nominal speciesMuricea fruticosaVerrill, 1869 due to the morphological similarity of colony growth patterns and the phylogenetic closeness based on the mitochondrial MutS gene (mtMutS); but differ mainly in the calyx form and composition of sclerites. The main morphological differences between the newMuriceaspecies are in their sclerite forms and color;M. ambaraesp. nov.has orange-colored colonies, thin leaf spindles and tuberculated blunt spindles, whileM. cacaosp. nov.has dark brown colored colonies, strong spinous spindles and an absence of tuberculated blunt spindles.Muricea molinaisp. nov.is phylogenetically close and morphologically similar toMuricea squarrosaVerrill, 1869 in the growth form of the colony and tubular calyces; but has dark brown colored colonies and has calyces from the base to the branch tips. With these three new species, the total number ofMuriceaspecies reported in the Mexican northwest region increases to twelve and a total of 24 nominal species in the Eastern Pacific.
Bifurcations, stability switches and chaos in a diffusive predator-prey model with fear response delay
Authors: Sui Mengting , Du Yanfei
Published: July 2023

Recent studies demonstrate that the reproduction of prey is suppressed by the fear of predators. However, it will not respond immediately to fear, but rather reduce after a time lag. We propose a diffusive predator-prey model incorporating fear response delay into prey reproduction. Detailed bifurcation analysis reveals that there are three different cases for the effect of the fear response delay on the system: it might have no effect, both stabilizing and destabilizing effect, or destabilizing effect on the stability of the positive equilibrium, respectively, which are found by numerical simulations to correspond to low, intermediate or high level of fear. For the second case, through ordering the critical values of Hopf bifurcation, we prove the existence of stability switches for the system. Double Hopf bifurcation analysis is carried out to better understand how the fear level and delay jointly affect the system dynamics. Using the normal form method and center manifold theory, we derive the normal form of double Hopf bifurcation, and obtain bifurcation sets around double Hopf bifurcation points, from which all the dynamical behaviors can be explored, including periodic solutions, quasi-periodic solutions and even chaotic phenomenon.

Published: July 2023

The CH146 Griffon helicopter is a Federal Aviation Administration (FAA) and Transport Canada certified commercial helicopter used by Canadian Armed Forces in military role, which is distinguished from the original design intent of the helicopter for commercial use. A regime based Structural Usage Monitoring (SUM) program is developed by Bell to meet the Canadian Government requirements documented in the Technical Airworthiness Manual (TAM). As part of the CH146 SUM, helicopter usage data recorded by the Flight Data Recorder (FDR) system is collected and flight conditions (regimes) are defined by using dedicated software tools. Helicopter usage is then compared with the baseline and by using the actual helicopter data on selected critical components and fatigue damage accumulation is performed. Finally, the calculated damage is evaluated to define recommended structural maintenance actions. Development of the CH146 SUM is completed and more than 50,000 flight hours accumulated FDR data is processed. The acceptance of the SUM program by the Canadian Department of Defence (DND) is expected in the summer of 2019.
Dynamic Time Warping to Quantify Structural Maneuver Variability

Regime recognition (RR) enables indirect characterization of high and low cycle fatigue damage to critical aircraft components during fleet usage based on structural maneuvers and measured loads from a flight test program. To ensure that an RR algorithm is suitable for usage or condition-based maintenance (UBM/CBM), it is arguably necessary to guarantee that it performs consistently during the design phase, when presented with structural maneuvers precisely executed by test pilots during a flight test program, and during deployment, when presented with general maneuvers flown by fleet pilots that include damaging structural maneuvers or something similar enough to be considered structural maneuvers. Dynamic time warping (DTW) is used to provide a framework to efficiently and automatically identify flight segments in fleet data that resemble flight-test structural maneuvers for which component loads are known; a normalized metric based on DTW distance measures is proposed to quantify the similarity and control the procedure to pull similar maneuvers from the fleet data. The resultant distribution of this metric is used to quantify variability of a structural maneuver of interest and in turn provide guidance on the number of unique maneuvers that should be used in a verification and validation (V&V) process to analyze a candidate RR algorithm.
Real Time Rotor Component Load Limiting via Model Predictive Control
Authors:   Georgia Institute of Technology, Mballo Chams , V. J.
Published: July 2023

This paper explores the use of Model Predictive Control (MPC) as a viable solution for real time load limiting for critical helicopter components that are subjected to significant fatigue loading. The development of the (structural) load limiting controller is posed as an optimal control problem where given a desired user defined max limit, the estimate of control margin associated with the component load limit is found and is provided as a cue to the pilot. The proposed load limiting via MPC, which makes use of an on-board reduced order model derived from a higher order Linear Time Invariant (LTI) model of helicopter coupled body/rotor/inflow dynamics, is described in detail. The proposed scheme is evaluated using nonlinear model simulations for its ability to limit harmonic pitch link loads and indirectly limit the peak-to-peak of the total pitch link load.
Setting the Record Straight on Failures and Successes in Army Aviation Development Programs Over the Past Forty-Five Years
Authors:   Georgia Institute of Technology, Schrage Daniel
Published: July 2023

Army Aviation Development Programs have had more failures than successes since beginning with the successful Utility Tactical Transport Aircraft System (UTTAS) and Advanced Attack Helicopter (AAH) development programs in the early 1970s. While these follow-on failures have often been blamed on either the Army user, Army developer or industry; they often come with biases from sideline participants without firsthand knowledge. The author of this paper has had mostly firsthand involvement and knowledge on these Army Aviation Development Programs over the past 45 years and he will seek to set the record straight. It will start with a review of Army Aviation Air Mobility Doctrine in the 1960s and it development and implementation in Southeast Asia, for which the author directly participated in. The initial implementation in South Vietnam was based on using off the shelf modified aircraft, predominantly helicopters. These lessons learned had a major impact on developing new aircraft and major modifications in the 1970s, e.g. UTTAS, AAH, CH-47D and OH-58D for which the author also directly participated in. There are critical lessons learned from this Air Mobility Doctrine development and the major aircraft programs which resulted from it, which are especially critical as the Army seeks major new development programs over the next decade. Also, it appears that the current focus on Urban Air Mobility (UAM) with the incorporation of new eVTOL aircraft, such as air taxis and unmanned aerial systems (UAS) into a low altitude Traffic Management (UTM) environment, also has a lot to learn from the Army's Air Mobility Doctrine development and the vertical takeoff and landing aircraft, e.g. helicopters,, that were developed to implement it.

The sustainable approach in design education is ubiquitous, yet too many barriers exist to its application in the real world. Plastic waste, for example, has been a potential architectural building element for years. Still, its application is uncommon because of the gap between waste processing and consumers' demand and knowledge as the main contributors to the waste volume. The paper aims to discuss the possibility of design class pedagogy with the reflection from the class " Architecture and Waste: Plastic by UMN." How the sustainable approach could affect students towards the actual act daily became the intention of the course? The method uses a practiced-based methodology by dividing the class into two balance sessions of theory and practice, thus creating loops of the design process. They were ignited by the discussion on sustainable design approaches in design, architecture and construction, and plastic waste, both potential and problems, and projecting the issue into everyday life. Plastic is used due to its abundance and can be recycled in small units. The result shows that focusing on the process and relating what the class and workshop are doing to everyday life could effectively impact students' thinking about sustainability. Furthermore, by doing deep research on certain materials, the student has a broader illustration of how the networks of sustainability work that will affect more significant decision-making, especially in architecture.

Building and construction technology education is a crucial component of architecture education, providing knowledge on tools and methods for designing and realizing building designs. While it provides knowledge as an input to other disciplines, it is also supported by the knowledge the other courses offer. On the other hand, these multilayered and interacting relations within the fields of architecture education may not be well-reflected in education curriculums, or implementation problems may occur. However, designing the architecture education curriculum based on these interacting relationships directly affects the education quality and educational outcomes. Within this respect, the AGU Department of Architecture provides a flexible curriculum design, which aims to provide experience in research and design during undergraduate architecture education and raise responsible team leaders or members. Therefore, building and construction technology courses of the curriculum are designed following the paths of the department’s and the university’s educational principles to engage all architecture disciplines with a multilayered and interacting approach. This paper explains the course design approach developed for and experienced with building and construction technology courses by aiming to contribute to the architectural design education literature from the technology education perspective. It sets forth the instructional design models and teaching methods used for designing the building and construction technology courses and also explains the course interactions within the curriculum.
