Published: July 2023

In this paper we assess long-term trends and habitat changes to understand the relationships between coastal beaver (Castor canadensis), salmon, shoreline alterations, large-scale dam removals and nearshore ecological restoration. From this work we conclude that the removal of two large scale dams in the Elwha River has benefited beaver use of the coastal zone through water quality changes that allow beaver to re-establish high-quality zones and the expansion of riparian zones that provide extensive new food resources to beaver. However, the lower river hydrodynamic processes continue to be disrupted by a 200-meter earthen dike installed by local government and landowners for flood protection in the Elwha coastal zone in the 1960’s. The dike acts as a driver of lower river geomorphology and has resulted in the formation of a large and persistent lateral bar along the lower river channel. Associated disrupted hydrodynamics are causing a critical coastal zone of the unimpounded lower river side channels to fill in. This channel habitat has decreased by 23%, with an annual average shrinkage rate of 13%, from pre-dam removal size, resulting in a decrease in both quality and quantity of nursery function for juvenile wild fish in a coastal zone that was historically documented to be the highest functioning for endangered juvenile salmon and trout. Inversely, physical changes including improved water quality in the adjacent impounded west side channel and continued expansion of riparian vegetation along the west delta lateral bar benefitted coastal beaver that recolonized the west delta after dam removals. The newly colonized coastal beaver may provide ecological engineering services to offset side channel loss as well as promote continued fish access. However recreational use was found to negatively impact beaver use of the area. We therefore recommend a series of additional ecosystem restoration actions that incorporate beaver as an ecosystem restoration component of the coastal zone. These actions include a public outreach program to encourage passive recreation measures to prevent negative impacts to beaver, and legacy, ecosystem scale restoration projects that reconnect the hydrodynamics of the west delta to complete Elwha ecosystem restoration. Together, these steps, if implemented, will result in a synergistic ecosystem restoration throughout the watershed to the benefit of the coastal ecosystem, including both beaver and salmon, as intended by the large-scale dam removal project.

Published: July 2023

The coaxial compound helicopters have obtained a lot of research interest due to their outstanding performance, especially in high speed flight. This rotorcraft could use the longitudinal cyclic pitch and the elevator to control the pitching moment during the flight. In order to investigate the effect of different longitudinal control strategy on the flight dynamics characteristics of this helicopter, a validated flight dynamics model is utilized to calculate the control derivatives, the bandwidth and phase delay, the attitude quickness, and the control inputs and pilot workload during the Pull-up & Push-over manoeuvre. The results indicate that control power of the longitudinal cyclic pitch is higher than that of the elevator, especially in hover and low speed forward flight due to the lack of the dynamic pressure on the elevator. The bandwidth and phase delay results demonstrate that both longitudinal control strategy could attain satisfactory small-amplitude response characteristics, and the attitude quickness results show that the helicopter capability in moderate to large control response is relatively high due to the additional damping provided by the rigid rotor. The manoeuvre simulation results indicate that using reasonable allocation between the longitudinal cyclic pitch and elevator is an efficient method to reduce the pilot workload and the maximum power consumption during manoeuvring flight.

Authors:   Turkish Aerospace Inc., Yucekayali Arda , Senipek Murat , Ortakaya Yuksel
Published: July 2023

A methodology to implement agility as a tradeoff parameter into multi-disciplinary optimization of a helicopter rotor is proposed. Being a qualitative evaluation measure and having no clear definition, agility is tried to be quantified through utilization of "ease", "speed" and "precision" metrics. The developed methodology utilizes a non-linear model predictive control approach to generate trajectory and control input history specifically to track the agile maneuver of interest. Deviation from reference path, state and input history and quickness are managed to determine integrated agility score. Then effect of rotor primary design parameters on agility characteristics is studied. A sensitivity analysis is performed to identify driving parameters and agility simulations are performed for four different maneuvers that are commonly used in nap-of-earth flights/missions. Slalom course, acceleration & deceleration, hurdle-hop and teardrop turn maneuvers analogous with ADS 33 Mission Task Elements are selected as the agile maneuvers to be considered and response surface analyses are performed to study the tradeoff between primary design parameters.

Published: July 2023

Aging aircraft experience increased structural damage and failures as a result of corrosion. Detection of corrosion at its earliest stages is an important step toward improving aircraft readiness rates, safety, and reducing maintenance cost. We have developed and demonstrated a new Paint Additive/Non-destructive Interrogation (PANDI) system. The paint additive component is an innovative implementation of an inorganic nano-sized additive (INA) which was pursued to test for its ability to enhance the non-destructive interrogation system. Although it is shown herein to increase the transparency of the paint to PANDI's operational wavelengths of light when incorporated in a military paint system, the interrogation device was able to reach such a high sensitivity that no paint additive is needed for the system to effectively identify corrosion. The non-destructive interrogator is shown to measure absorption of light by hydroxyl ions accompanying the earliest formation of corrosion.
Model-based Engine Health for Turboshaft Engines with Limited Instrumentation
Authors:   GE Aviation, Cornelius Daniel , Hannula Scott
Published: July 2023

Helicopter health and usage monitoring has lagged large commercial aircraft due to the limited instrumentation and high mission complexity of typical rotorcraft. To counteract these challenges, a model-based framework is introduced to utilize knowledge of engine and aircraft operation to determine (either on-board or off-board) the overall engine health and margin as well as module health based solely on aircraft Health and Usage Monitoring System (HUMS) data. The engine and module health can then be used to estimate remaining Time on Wing (TOW) as well as most likely condition-based maintenance for the engine.

Published: July 2023

The Autonomous Sustainment Technologies for Rotorcraft Operations-Structures (ASTRO-S) project between U. S. Army Combat Capability Missile Center, Aviation Development Directorate-Eustis (FCDD-AMV-E) and Sikorsky developed and validated a range of technologies to enable reduced airframe maintenance burden, increase operational availability, and provide key enabling technologies relative to Army's transition to the new paradigm of Maintenance Free Operational Periods (MFOP) for the rotorcraft of the future. Methods were developed for autonomous characterization of major damage and residual strength expressed as a Structural Health Index (SHI) for advanced durable and damage tolerant composite aerospace structural assemblies with redundant load paths, enabling targeted inspections and strength-based fly / watch / repair decisions. A number of sensing technologies including fiber-optic strain measurement and piezo-based structural health assessment, along with a number of innovative advanced algorithms that intelligently use changes in monitored structural responses, were implemented in a comprehensive architecture to detect, localize, and assess the severity of structural damage. Extensive testing on full-scale, multiload-path composite structures to assess feasibility and effectiveness of the developed technologies, as well as understand application and transition challenges, has convincingly shown that damage detection, localization, and severity assessment in an autonomous fashion is feasible. Further, it was shown that the concept of a trendable SHI to assess residual strength, is viable, although additional full-scale test cases are needed to further validate and mature the approach. Overall, these key findings affirm suitability of the technical approach and associated algorithms for reducing maintenance burden by triggering rather than scheduling inspections and potentially deferring repairs in high op-tempo environments. These structural health management technologies will be key enablers supporting Army's future rotorcraft when operating in an untethered multi-domain battle space.

The Government Internal Supervisory Apparatus (APIP) is often under pressure which can lead to increased stress and affect the quality of the audits conducted. This study aims to examine the factors that influence Reduced Audit Quality Practices (RAQP). The data used in this study is primary data sourced from the auditors of the Inspectorate General of the Ministry of PUPR with a total sample of 151 respondents. Data was obtained through a closed questionnaire. The sampling technique is random sampling. We used Moderated Regression Analysis (MRA), including the t-test and the R2 test as the analysis technique in this study. The results of the analysis show that role conflict, role ambiguity, role overload, and time pressure have a positive effect on RAQP. The moderating effect of resilience is able to weaken the positive influence of role conflict and role overload on RAQP. On the other hand, resilience cannot moderate the positive influence of role ambiguity and time pressure on RAQP.

Elevated levels of IL-12p40 have been observed in the cerebrospinal fluid and serum of MS patients, and it has been suggested that genetic variants in the IL-12B gene may contribute to MS susceptibility and/or pathogenesis. In this study, we investigated the association between MS and IL-12B gene rs17860508 and rs3212227 polymorphisms in the Turkish population. We identified two polymorphic regions in the IL-12B gene using bioinformatics tools and genotyped 351 MS patients and 221 healthy controls for these variants. Our results showed a significant association between the IL-12B rs17860508 polymorphism and MS, but no significant relationship between rs17860508 genotype distribution and allele frequency and MS age onset or subtypes. Genotype distribution and allele frequency of IL-12B rs3212227 polymorphism did not show any significant association with MS directly. However, AC genotype of IL-12B rs3212227 polymorphism in early-onset multiple sclerosis (EOMS) was a risk factor according to age of onset. Additionally, we observed a higher risk for the relapsing-remitting multiple sclerosis (RRMS) subtype in females. This is the first study to investigate the association between IL-12B polymorphisms and MS in the Turkish population.

The Number of NGOs in Bangladesh is increasing in a rocket trajectory fashion. However, the accountability issues are not still adequate. This study makes an endeavor to find out “how do the NGOs prioritize their importantstakeholders e.g. the donors, the beneficiaries (the clients), the NGO-themselves, and other stakeholders from accountability perspectives?”Following multi-staged sampling technique, this study carries out 17-semistrutured interviews of the NGO-employees covering whole Bangladesh. Further, two international donor agencies’ three employees are also interviewed. The interviewees’ content analyzed data reveal, for accountability purpose, NGOs give minimal importance to the beneficiaries (the clients) than those of the donors and the government in the Bangladeshi scenario. Future researcher may carry out similar study on the beneficiaries in the context of Bangladesh, or may carryout similar research in a different country.
The Nexus between Savings Gap, Foreign Exchange Gap, and Foreign Direct Investment Inflows into Asia: Two Gap Model Analysis with Panel Data Approach
Authors: Chowdhury Piyali Roy , A Anuradha
Published: July 2023

The study analyses the nexus between Savings (Savings- Investment), Foreign Exchange (Import- Export) Gap and net Foreign Direct Investment (FDI) inflow into Asian Countries. Economies for this analysis are taken from Newly Industrialised Countries (NICs) based on the valuation of GDP of the respective countries. Six countries, such as, China, India, Indonesia, Thailand, Malaysia and Philippines are considered for this study over a period 1982-2016. Using Panel Data Approach, the analysis has been able to find out a long run cointegration between Savings Gap and FDI as well as Foreign Exchange Gap and FDI. As proposed by Two Gap Model, the influence of FDI has been found on both the variables. Whereas the effect of savings gap on net FDI inflow is positive and significant for the said period with a negative Error Correction Term which proves the movement from short run disequilibrium to long run stable equilibrium. After proving the direction of causality, the short run joint influence of savings gap with its lagged values has been checked. Through Wald Test, the result is proved to be significant. On the other hand, the effect of Foreign Exchange Gap on FDI is not significant in nature. Finally, from the study, it is suggested that if domestic savings for all the six countries together are given importance from the level of respective Governments, the Savings Gap may be reduced which will indicate less dependence on foreign investments into these countries. Being NICs, self-funding of future investments is always preferred which is only possible if countries are contended with adequate capital accumulation on their own in previous periods.
Quantum Mechanical Approach to Electrophysiology

Published: July 2023

за последние 100–120 лет изучения механизмов возникновения и генерации биопотенциалов мозга, нервов, мышц сложилось твердое убеждение, что биопотенциалы могут описываться в рамках стохастических подходов. Вместе с тем открытие эффекта Еськова–Зинченко (статистической неустойчивости выборок любых параметров гомеостатической системы) существенно подрывает возможности стохастики в электрофизиологии. Отметим, что для описания биопотенциалов мы можем взять в качестве первой фазовой координаты x1 (t) величину этих биопотенциалов, а в качестве второй — x2=dx1/dt — скорость их изменения. В таком двумерном фазовом пространстве состояний мы вводим аналог принципа неопределенности Гейзенберга (на вариационные размахи ∆x1 и ∆x2 ) и тем самым приближаем электрофизиологию к аппарату квантовой механики. В работе представлены различия и сходства между квантовой механикой и электрофизиологией гомеостатических систем. Вместо статистических функций f(x) предлагается рассчитывать параметры псевдоаттракторов в двумерном фазовом пространстве состояний (биопотенциалов) вектора x (t) = (x1,x2)T.

for the last 100-120 years of studying the brain, nerves, muscles biopotential generation they were described as stochastic processes. The discovery of the Eskov–Zinchenko effect (stochastic instability of any homeostatic system sample datasets) makes it impossible to apply stochastic laws to electrophysiology. We can define biopotentials with their magnitude x1 as the first phase coordinate and their variation rate x2=dx1/dt as the second coordinate. In such a 2D phase space, we defined an analog to the famous Heisenberg uncertainly principle (for ∆x1 and ∆x2 variation ranges). We also present the similarities between electrophysiology and quantum mechanics. We suggested to estimate the properties of pseudo-attractors in the 2D phase space of biopotentials (for the x (t) = (x1,x2)T vector) instead of the statistical f(x) functions.

Authors: Singla Tanvi , Sharma Sapna , Kumar Bhuvaneshvar
Published: July 2023

The present work addresses the axisymmetric flow of Maxwell fluid between two stretchable and rotating disks with porous regime. The influence of velocity slip and convective heat transfer are considered to govern the flow.  The energy equation is modeled using Cattaneo-Christov heat flux model. The resulting mass, momentum and energy PDE’s are converted to ODE’s by using the Von Karman similarity transformations. Successive linearization method is implemented for numerical solution. The tangential velocity of the fluid increases with the rotating speed of the disks. The enhancement in the convective heat transfer of lower disc results in the rise of temperature profiles whereas temperature falls with the rise in Biot number of the upper disk.

Authors: Salehi Fakhreddin , Cheraghi Rana
Published: July 2023

In this study, kiwifruit slices were osmotically dehydrated in different hypertonic sucrose solutions  and assisted with or without ultrasound. Sucrose concentrations (in three levels of 20, 30, and 40 °Brix), sonication power (in three levels of 0, 75 W, and 150 W), and treatment time (in 8 time intervals: 10, 20, 30, 40, 50, 60, 70, and 80 min) were the factors investigated concerning colour parameters including a* (redness: green to red), b* (yellowness: blue to yellow), L* (lightness), and ?E (total colour difference), and also surface area changes of the kiwifruit slices during osmotic dehydration (OD). As the sonication power (40 kHz) increased from 0W to 150W, the lightness index values of kiwifruit slices reduced from 64.8 to 60.6 (30°Brix). Also, with increasing sucrose solution concentration from 20°Brix to 40°Brix the lightness index values of kiwifruit slices decreased from 61.8 to 59.3 (power=150W). The results showed that the mean of ?E index values of dehydrated kiwifruit slices increased during OD period. The highest ?E index (8.03) and lowest surface area (8.64 cm2) values were for the kiwifruit slices treated by the lowest ultrasound power (0W) and the highest sucrose solution (40°Brix). The average surface area of fresh kiwifruit slices, dehydrated samples, hot-air drying samples, and rehydrated samples were 9.50 cm2, 9.05 cm2, 6.44 cm2, and 7.82 cm2, respectively. The results illustrated that the MMF (Morgan-Mercer-Flodin) equation was the best equation to explain the ?E index changes of untreated and treated kiwifruit slices during OD (the average R2=0.995, the average SSE=0.171, and the average RMSE=0.177).

Board Gender Diversity, Board of Commissioner Size, Firm Size, Leverage as well as Return on Equity (ROE) were further used in this study as control variables. This study includes companies concerning the manufacture and mining industry that is registered on the Indonesia Stock Exchange website from year 2015 to 2021. The findings of this research show that ERMADV significantly affects firm performance and value. In addition, it was discovered that ESG plays a large moderating influence. ESG suggests that an advanced ERM framework will prioritize risks associated with ESG-related aspects if it is resilient and integrated. As a result, this strategy will direct organizations in developing ethical decision-making strategies, improving financial performance and firm value.

–Medical laboratories staff are exposed to professional bio-hazards on a regular basis if proper protective standards are not put in place, both their health and safety may be at danger. The initiative of this study is based on the articulation of the knowledge, attitude and practice regarding biological hazards among the laboratory staffs. Innumerable accidents happen due to lack of sufficient information about laboratory safety procedures, a callous attitude, and incorrect administration in the laboratory. This study was carried out among the staff of selected Hospitals and Diagnostic Centers at Jashore region to evaluate the KPA of laboratory bio-safety. In both approaches and manner, a descriptive cross-sectional survey was conducted among 192 laboratory staff from 52 Hospital and Diagnostic Centers. Data was gathered from a structured self-observed questionnaire and checklist, which were created and evaluated based on existing research and guidelines on universal work considerations. A total of 192 staffs who consented were included in the study. Where 150 (78.1%) male and 42(19.9%) female. 116 (64.4%) were 20-30 years age group, 49 (25.5%) were over 10 years of experience and 129(67.2%) married respondents. In the study 166 (86.5%) respondents work more than 8 hours in the lab and 59 (30.7%) were overweight. 66(34.4%) of staff have good knowledge on bio-safety, good attitude and practice 46 (24%) and 25(13%) on bio-safety respectively. Within the demographic information observed, only the working hour displayed significant (p=0.000) influence on the bio-safety knowledge. Age of the worker (p=0.000) and experience (p=0.001) had great influence on bio-safety attitude. Among the participants 104 (54.2%) received formal safety training and 155(80.7%) aware about universal work precaution. 145 (75.5%) never washed hands before putting gloves and 70(36.5%) always used PPE. Average (Mean ± SD) of laboratory staff knowledge, practice and attitude 71.72±10.40, 63.21±12.16 and 70.68±14.20 respectively. Overall, the data suggest that good knowledge and attitude to bio-safety practices between lab staff was indicated and their practices need to be more improved. Arrangement of training programs, proper monitoring and sticking to legislation must be implemented by the governance body to rise conversance of the laboratories staff about strict laboratory techniques and biohazards.

Complex networks are a diverse set of networks found in various fields, such as social, technological, and biological networks. One important task in complex network analysis is link prediction, which involves detecting missing links or predicting future link formation. Many methods based on network structure analysis have been developed for link prediction, including network representation learning (NRL) models that represent nodes in a low-dimensional space. Fusion-based attributed NRL methods are particularly effective, as they capture both content and structure information. However, NRL models for link prediction are binary classification models, which face challenges in identifying negative links and prioritizing predicted links. To address these challenges, we propose a novel approach that treats link prediction as a novelty detection problem. Our approach uses the Local Outlier Factor (LOF) algorithm to quantify the novelty of non-existent links based on the representations of existing links. Our experimental results show that our proposed approach outperforms existing methods, particularly when used with fusion-based attributed NRL models

In the research work, the peculiarities of the spread of a meteorological phenomenon dangerous for agriculture – the dry wind in the territory of Eastern Kazakhstan are considered. To achieve this goal, on the basis of long-term data, favorable conditions for the dry wind and the number of days that have passed with the dry season were calculated. In addition, the features of the distribution of the main climatic indicators in the East Kazakhstan region were described. According to the results of the study, during the year favorable meteorological conditions for dry wind are formed in the period from April to November, and the phenomenon of dry wind occurs in May-September. According to the results of calculations, on average, during the warm period of the year in the east of Kazakhstan, the number of favorable conditions for dry wind reaches 60 days, and the number of cases with dry wind reaches 30 days. And in mountainous areas, where there is no shortage of humidity, dry wind is not observed (MS Markakolsky Reserve, Leninogorsk). The areas where the dry wind phenomenon is most often observed correspond to flat and low-mountainous areas with low relative humidity and high wind speed (MS Akzhar, Ayagoz). The results obtained during the research work can be used by specialists working in the field of agriculture, climate research and forecasting of dangerous agrometeorological phenomena.
