Fear of the risk of poisoning from wild mushrooms increases the production of cultivated mushroom species. Oyster mushrooms, which are among these mushroom species, have been preferred in recent years due to some advantages in production. It is very important to ensure regional diversity in production environments in increasing mushroom production. In this study, it is aimed to expand mushroom production in Van and its surroundings and to investigate the efficiency of production in straw and inactive tea wastes that can be easily obtained by the producers of the region. The study, which was established with wheat straw, tea waste and ready-made mushroom production kits, was designed in a randomized plot design with four replications. The parameters of the first harvest, carpophore weight, total yield, carpophore measurements, macro and micro elements were examined in the mushrooms obtained. In the study, it was seen that the mushroom data produced in the tea media were closer to the mushroom data obtained from the ready-made kits obtained from the companies producing mushrooms.

Organic agricultural product is the food whose naturalness is certified and should not lose its naturalness until the end user. In this research, it was aimed to reveal the approach of the logistics (transport) sector employees to the transportation of organic agricultural products. The research was conducted in the form of a face-to-face survey on 115 logistics employees in Iğdır. The collected data were evaluated numerically and proportionally, and analyzed by statistical methods also including the decision tree CART algorithm. Logistics firm employees in the rate of 96.5% claimed to know what organic food is, 100% to eat organic food, and 59.1% even claimed to know what organic food certification is, but only 4.3% of the participants answered the question of "What do you think is organic food" as "organic certified food" for organic food, and 27.8% said that they pay attention to the certificate when purchasing organic food. Even, 27.8% of the participants claimed that they understood whether the food was organic when they looked at the product. Therewithal, 78.3% of the logistics employees stated that they do transportation of organic food and transportation time (94.8%), the cooling system (100%), and the cleanliness (100%) are more important criteria for organic food transportation compared to normal food. Apart from these, they stated that the employees of the sector other than themselves did not have sufficient knowledge (69.6%) about organic food transportation, while they claimed that they had sufficient knowledge (61.7%) about the subject. Consequently, although the logistics company employees in Iğdır region claimed that they knew organic food in general, it was revealed that their level of knowledge was not sufficient. Despite these results, it was observed that the personnel knew what to pay attention to in organic food transportation. It was concluded that the use of TV-Radio and the Internet could be used as a tool to eliminate the lack of information on the subject.

The food culture, which gains meaning according to the life perception of countries in the traditional and modern world, brings different perspectives to gastronomy. With the Slow Food movement, which is one of these perspectives, it is essential to bring an up-to-date approach to the dishes that have been forgotten in traditional food culture. While the slow food movement ensures the sustainability of the food culture, it also supports the preservation of the 'sense of taste'; It serves to raise awareness in setting tables together and determining the importance of common points, in food production with traditional methods and in using techniques. Quantitative data collection techniques are used to determine whether the services of the stream reach the target. The cycle of the slow mobility current is first production, then consumption. The aim of this study is to determine the extent of slow food perceptions and slow eating attitudes of the people living in Gökçeada district of Çanakkale province. For this purpose, a survey method consisting of a systematic question form was applied to the local people of Gökçeada, which constitutes the sample of the study, to determine the perception of slow food and the effect of this perception on slow eating attitudes. According to the results obtained from the survey data, it was determined that the participants were women with a participation rate of 68.5% and they constituted the majority of the study. 92.4% of the participants who stated that they knew about the Slow Food movement correctly defined Slow Food. It was determined that the participants had a positive participation of more than 50% in the questions asked to determine the local food consumption tendency. Therefore, it can be said that the participants have a high level of local food demand, interest and consumption tendency. Among the 6 hypotheses examining the relationship between Slow Food consumption and demographic characteristics, the marital status and age hypothesis were accepted and the others were rejected.

The aim of this study was to determine the effect of anesthesia with a combination of butorphanol, medetomidine and ketamine on blood gas parameters during ovariohysterectomy in queens. Nineteen queens of different breeds, between 6 and 72 months of age, which were neutered, were used in the study. Before anesthesia, 1 mL of blood was taken from Vena cephalica antebrachi to a heparinized syringe and blood gas parameters were evaluated. Queens determined to be healthy as a result of clinical examination and laboratory analyzes were taken under general anesthesia for ovariohysterectomy. Butorphanol (0.01 mg/kg, IV) was administered for anesthesia induction, medetomidine (0.08 mL/kg, IV) was administered 5 minutes after following the induction and ketamine (5-7.5 mg/kg, IV) was administered intravenously 10 minutes later. At the 10th minute of ketamine administration, blood samples were taken from the queens again. Blood gas parameters such as pH, pCO2, pO2, sO2, Na, Ca, K, Cl, Glu, Lac, BE and HCO3 were evaluated in blood samples taken before and during anesthesia. It was determined that pH, pO2, sO2, BE and HCO3 levels were lower and pCO2 and lactate concentrations were higher in anesthesia-induced queens compared to pre-anesthesia. As a result, it was thought that monitoring blood gas parameters in queens undergoing ovariohysterectomy may be useful to prevent complications that may occur before and after the operation.

Atmospheric Density Estimation Techniques for Aerocapture

Published: February 2023

Aerocapture is a promising orbit insertion strategy that can reduce propellant mass requirements for planetary orbiters. Reliable aerocapture requires active guidance, navigation, and control systems for robust performance. Such systems rely on accurate models of the downstream density environment for accurate targeting capabilities. Two density profile prediction techniques are introduced that use density histories computed from navigation measurements to improve aerocapture targeting accuracy: the density interpolator and the ensemble correlation filter. The density interpolator stores density data on the descent portion of the vehicle’s trajectory, interpolating density values from this array during guidance predictions; whereas the ensemble correlation filter attempts to match density history data to onboard density profiles. A hybrid of the two methods is also considered. Both Earth and Venus are considered as planetary targets. A discrete-event control aerocapture scenario is considered, using Monte Carlo methods to assess the proposed methods’ performances and demonstrate improvement in both the apoapsis error and entry corridor width. Density interpolator strategies were shown to perform consistently better than the density scale factor approaches. Ensemble correlation strategies were shown to provide a larger performance benefit potential as compared to interpolator strategies, particularly in cases where density model confidence is high. However, density interpolator strategies were shown to improve performance over a wider range of Monte Carlo simulation conditions.

Published: February 2023

Tilted fiber Bragg grating (TFBG) sensors were demonstrated to simultaneously measure the material thermomechanical and refractometric state in which they are embedded. In this work, for the first time, TFBGs are investigated for three-parameter monitoring of space-qualified NuSil® CV16-2500 silicone operating during high-vacuum ultraviolet (UV) exposure. The first part of the work is focused on the ultraviolet effect on the TFBG spectrum when the sensor is 1) directly exposed to the radiation, 2) covered by a thin cover glass, and with a Kapton layer on top. Successively, the silicone is used as an adhesive in a sandwich structure in which the TFBGs are embedded and exposed under high vacuum to various UV/vacuum UV intensity radiations and durations. The sensors’ spectra were acquired and demodulated to detect the silicone strain–temperature–refractive index variations and correlate the silicone refractometric changes with the equivalent exposure solar hours. The second part of the paper is on silicone degradation state evaluation using the same sensor but during a direct exposure of the adhesive to the radiation. This allowed the UV effects on the silicone to be enhanced but needed a method to compensate for the damaging effect of UV radiation on the TFBG spectrum.

Published: February 2023

The Mars Entry, Descent, and Landing Instrumentation 2 (MEDLI2) sensor suite collected heating and pressure data during entry of the Mars 2020 Perseverance rover into Mars’s atmosphere. MEDLI2 included temperature, heat flux, and pressure sensors on the heat shield and backshell. This paper covers inverse estimation of surface heating based on the MEDLI2 instrumented sensor plugs, which are a network of thermocouples embedded in thermal protection system plugs across the aeroshell. Monte Carlo analysis was conducted to assess the sensitivity of calculated surface heat rate and temperature to uncertainties in thermocouple depth and material properties, and a variance decomposition method was employed to understand the relative contributions of each uncertainty parameter. Performing this analysis using results from the inverse analysis tool FIAT_Opt was found to require an extremely high computation time; thus, machine learning models were trained and evaluated as a surrogate for FIAT_Opt. This paper demonstrates that machine learning models can be efficient, accurate alternatives to state-of-the-art inverse analysis tools like FIAT_Opt, especially for computationally expensive processes. Ensuing sensitivity analysis showed that the main drivers for overall uncertainty in the reconstructed heat flux and heat load were heat capacity and thermal conductivity on the backshell, and they were thermal conductivity and thermocouple depth on the heat shield.
Novel Source–Sink Model for Space Environment Evolution with Orbit Capacity Assessment

Published: February 2023

The increasing number of anthropogenic space objects (ASOs) in low Earth orbit (LEO) poses a threat to the safety and sustainability of the space environment. Multiple companies are planning to launch large constellations of hundreds to thousands of satellites in the near future, increasing the probability of collisions and debris generation. This paper analyzes the long-term evolution of the LEO ASO population with the goal of estimating LEO orbital capacity. This is carried out by introducing a new probabilistic source–sink model. The developed source–sink model is a multishell multispecies model, which includes different object species, such as active and derelict satellites, and debris. Furthermore, debris are divided into the following two subgroups: trackable and nontrackable debris, the last ones representing a significant hazard for active satellites. In addition, the proposed model accounts for collision events and atmospheric drag effects, which include the influence of solar activity. Indeed, the Jacchia–Bowman 2008 thermospheric density model is exploited. The results prove that considering untracked debris within the model produces more collisions, and therefore a smaller population of active satellites affecting the safety of LEO and its orbital capacity.
Wake Vortex Far-Field of a Generic Transport Aircraft Affected by Oscillating Flaps
Authors: Ruhland Johannes , Breitsamter Christian
Published: February 2023

The influence of oscillating trailing-edge flaps of a generic transport aircraft on the middle and far fields of the wake vortex system is investigated. The aim is to be able to reduce separation distances between aircraft during approach in order to increase capacity at airports. By introducing a certain disturbance by means of oscillating flaps in the near field, the long-wavelength Crow instability should be excited in the further downstream development. The evolution of the wake vortex system is investigated using a large-eddy simulation approach. The wake vortex system is examined up to 133 spans downstream for two high-lift configurations. A nonactuated configuration with statically deflected flaps is compared to a configuration with actuated flaps. The results show that the long-wavelength Crow instability cannot be excited by actuated trailing-edge flaps. However, a faster decrease of the dimensionless circulation over the downstream position can be observed for the actuated configuration compared to the nonactuated configuration, due to a faster diffusion of the rolled-up vortex pair. Furthermore, the averaged induced rolling moment on an aircraft [with the International Civil Aviation Organization’s (ICAO’s) classification of “light”] encountering the wake vortex of the actuated configuration (ICAO’s classification of “heavy”) is up to 32.5% lower than for a follower aircraft, which is entering the wake vortex of the nonactuated configuration.
Robust Neurocontrol for Autonomous Dynamic Soaring
Authors: Kim Eric J. , Perez Ruben E.
Published: February 2023

The flight endurance of small unmanned aerial vehicles can be significantly extended through the exploitation of naturally occurring wind phenomena. However, due to the limited computational hardware on board such aircraft and the uncertain, stochastic nature of real-world environments, there is a need for efficient and robust strategies that exhibit generalized behavior. In addressing these objectives, recent efforts have explored the use of artificial intelligence training algorithms and neural networks for the design of autonomous control schemes that exploit such wind phenomena. This study incorporates the Neuroevolution of Augmenting Topologies algorithm with domain randomization to train robust neurocontrollers that can control an aircraft along sustained traveling dynamic soaring trajectories in the presence of uncertainties and disturbances. This work presents the developed strategy for integrating robustness in neural network control systems, provides a method for quantifying and comparing robustness, and introduces an approach for identifying the network characteristics that contribute to the evolved robust behavior.
Noninvasive Measurement Methods for Transient Flows in Wind Tunnels
Authors: Marcheggiani Joseph P. , Glegg Stewart
Published: February 2023

The noninvasive measurement technique proposed in this paper uses the response of a Kevlar wall in a wind tunnel to infer the angle-of-attack time history of an airfoil in the working section undergoing a pitching motion. Recent work has shown that the displacement of a Kevlar wall can be measured accurately via an optical method to obtain the loading on an airfoil in a steady flow, but the feasibility of using this method on time-varying flows has yet to be explored. Based on thin airfoil theory, a model of an airfoil undergoing a sudden change in angle of attack is considered, and the pressure along the wall was found using potential flow theory. The process of relating the pressure field to the wall displacement is presented, and it is shown how the wall response can be found. The membrane response is then used to obtain estimates of the angle-of-attack time history of the airfoil through an inversion process. It was found that the response of the Kevlar wall is dominated by the effects of the circulation around the airfoil and not its wake, and so the unsteady airfoil lift is measured with the proposed method, without the need for a force balance with a fast response time. The limitations and the applications of the proposed measurement method are discussed.
Large-Eddy Simulation of Boundary-Layer Transition over a Zigzag Trip
Authors: Zhang Jin , Zhang Jin , Fohlmeister Lajos , Scholz Peter
Published: February 2023

Wall-resolved large-eddy simulations (WR-LES) are conducted to study transitional and turbulent boundary-layer properties and flow structures downstream of a zigzag trip on the low-Reynolds-number SD7032 airfoil at [Formula: see text] and [Formula: see text] and angle of attack [Formula: see text]. Without a zigzag trip, the airfoil features a prominent laminar separation bubble on the suction side. First, a verification and validation study of the LES method is conducted for the zigzag trip at a roughness-height-based Reynolds number [Formula: see text]. The boundary-layer velocity profiles and the integral parameters are compared with experimental data acquired using a long-distance [Formula: see text]-particle image velocimetry setup in a wind tunnel. In the LES, if the zigzag tape is thick enough to trigger transition just behind the tape, the transition to turbulence is generally quicker than what was observed in the experiment. Although the general phenomenology and the development of the turbulent boundary layer after transition are consistent with the experimental data, there remain some differences in the exact length of the transitional region and also in the associated airfoil drag. A zigzag tape with [Formula: see text] or thicker induces transition quickly behind the trip through a shedding process of the shear layer created by the tape. The boundary layer behind the zigzag tape features prominent three-dimensional vortical structures emanating from the zigzags that persist over long chordwise distances and well into the turbulent boundary layer. Nevertheless, in a spanwise-averaged sense, the integral thicknesses of the newly created turbulent boundary layer are actually quite similar to a two-dimensional boundary-layer theory solution, given that the tape has a suitable thickness. In contrast, an overly thick tape will generate a thicker turbulent boundary layer, where the increased displacement and momentum loss are sustained and also contribute to total drag.
Iterative Maneuver Optimization in a Transverse Gust Encounter

Published: February 2023

This paper presents a framework based on either iterative simulation or iterative experimentation for constructing an optimal, open-loop maneuver to regulate the aerodynamic force on a wing in the presence of a known flow disturbance. The authors refer to the method as iterative maneuver optimization and apply it in this paper to regulate lift on a pitching wing during a transverse gust encounter. A candidate maneuver is created by performing an optimal control calculation on a surrogate model of the wing–gust interaction. Execution of the proposed maneuver in a high-fidelity simulation or experiment provides an error signal based on the difference between the force predicted by the surrogate model and the measured force. The error signal provides an update to the reference signal used by the surrogate model for tracking. A new candidate maneuver is calculated such that the surrogate model tracks the reference force signal, and the process repeats until the maneuver adequately regulates the force. The framework for iterative maneuver optimization is tested on a discrete vortex model as well as in experiments in a water towing tank. Experimental results show that the proposed framework generates a maneuver that reduces the magnitude of lift overshoot by 92% for a trapezoidal gust with peak velocity equal to approximately 0.7 times the freestream flow speed.

Agriculture globally is still dominated by small-scale farmers which means that investment is still needed to change their quality of life for the better. Investment in innovation in agriculture is expected to not only alleviate poverty, but also improve the welfare of farmers and rural communities. To create this, collaboration between agricultural actors is needed, so as to encourage actors to play roles according to their respective functions, strengthening each other so that in aggregate it can increase farmers' productivity. Productivity growth, agricultural efficiency and reducing the impact of agriculture on the environment arise due to various studies conducted on the agricultural sector. Rural poor still rely on agriculture as their main livelihood, therefore investment in agriculture is an important factor in efforts to reduce poverty in rural areas, namely by improving agricultural performance. Collaboration between the government and the private sector is expected to improve soft skills and hard skills from each party, so as to improve services to agricultural stakeholders optimally. The government and agricultural stakeholders always collaborate with each other to encourage agricultural ecosystems that are able to overcome food insecurity and create sustainable agriculture. With the right model of iolaborasi, science-based innovation can encourage the strengthening of the agricultural industry and increase the level of welfare of smallholder farmers in rural areas.

Healthcare workers have been under tremendous psychosocial strain since the advent of the COVID-19 pandemic, particularly those on the frontlines such as nurses. This is especially true in low- and middle-income countries such as South Africa, where lack of resources and support exacerbate challenges. Five focus group discussions were conducted with frontline nurses at primary, secondary, and tertiary healthcare institutions in Cape Town, South Africa. Participants reported significant stress emanating from all spheres of their life, with the acute stressors of their work having largely adverse consequences on their lives in their homes and communities. A lack of organisational support was evident, with participants highlighting various ways in which the psychosocial strain they were under may be alleviated. Healthcare facilities should investigate both individual and organisational interventions aimed at better supporting their invaluable frontline teams. These include tailored psychological support services, sufficient time for rest, adequate staffing and medical supplies, effective leadership, COVID-19 specific training, and the promotion of teamwork. However, facilities should also extend their concern to the families of staff by reducing potential risk of exposure through a variety of measures including providing transport and voluntary isolation accommodation. Such interventions are important not only for the healthcare workers and their families, but also for the smooth functioning of healthcare institutions as the pandemic draws on into an uncertain future.
