Emulating present and future simulations of melt rates at the base of Antarctic ice shelves with neural networks
Authors: Burgard Clara , Jourdain Nicolas C , Mathiot Pierre , Smith Robin , Schäfer Rieke , Caillet Justine , Finn Tobias S. , Johnson J. Emmanuel
Published: May 2023

Melt rates at the base of Antarctic ice shelves are needed to drive
projections of the Antarctic ice sheet mass loss. Current basal melt
parameterisations struggle to link open ocean properties to ice-shelf
basal melt rates for the range of current sub-shelf cavity geometries
around Antarctica. We present a novel parameterisation based on deep
learning. With a simple feedforward neural network, or multilayer
perceptron, acting on each grid cell separately, we emulate the behavior
of circum-Antarctic cavity-resolving ocean simulations. We explore
different neural network sizes and find that, in all cases containing at
least one hidden layer, this kind of emulator produces reasonable basal
melt rates for our training ensemble, closer to the reference simulation
than traditional parameterisations. For testing, we use an independent
ensemble of simulations that was produced with the same ocean model but
with different model parameters, different cavity geometries and
different forcing. In this challenging test, traditional and neural
network parameterisations yield similar results on present conditions.
In much warmer conditions than the training ensemble, both traditional
parameterisations and neural networks struggle, but the neural networks
tend to produce basal melt rates closer to the reference than a majority
of traditional parameterisations. These neural networks are therefore
suitable for century-scale Antarctic ice-sheet projections.
A Signature-based Hydrologic Efficiency Metric for Model Calibration and Evaluation in Gauged and Ungauged Catchments
Authors: Kiraz Melike , Coxon Gemma , Wagener Thorsten
Published: May 2023

Rainfall-runoff models are commonly evaluated against statistical
evaluation metrics. However, these metrics do not provide much insight
into what is hydrologically wrong if a model fails to simulate observed
streamflow well and they are also not applicable for ungauged
catchments. Here, we propose a signature-based hydrologic efficiency
(SHE) metric consisting of hydrologic signatures that can be
regionalized for model evaluation in ungauged catchments. We test our
new efficiency metric across 633 catchments from Great Britain. Strong
correlations with Spearman rank and Pearson correlation values around
0.8 are found between our proposed metric and commonly used statistical
evaluation metrics (NSE, KGE, NP…) demonstrating that the
proposed SHE metric is related to existing metrics as much as these
metrics are related to each other. For ungauged catchments, we
regionalise the three signatures included in SHE and find that 78% of
catchments have an absolute difference of SHE values between gauged and
ungauged cases of less than 0.2. This difference increases where the
regionalized bias and variance signature values are different to the
observed ones. It means that SHE metric is applicable for model
evaluation in ungauged catchments if its signatures can be regionalized
well.
Absolute instability of moisture-coupled waves on the equatorial beta-plane
Authors: MacDonald Cameron G
Published: May 2023

The instabilities produced by a linear model of the tropical atmosphere
coupled to a prognostic equation for water vapour are investigated. For
parameter regimes relevant to the Indo-Pacific warm pool, the long-time
asymptotic behaviour of the unstable waves is found to be absolutely
unstable, so that the amplitude of disturbances will grow in time at
every point in the domain. Other limits of the system do not produce
this same behaviour at these length and time scales. It is shown that
the resultant long-time behaviour of the instability is characterized by
roughly equal roles for temperature and moisture fluctuations in setting
the thermodynamic tendency of the waves. Under the assumption of a
zonally varying flow, it is shown analytically that localized regions of
instability may be formed, again using parameter choices relevant to the
warm pool. The dynamics and thermodynamics of these local instabilities
show some correspondence with the observed development of the
Madden-Julian Oscillation as it propagates through the warm pool.
A generalized relationship linking water balance and vegetation carbon uptake across site-to-regional scales

Published: May 2023

The linear relationship between gross primary productivity (GPP) and
evapotranspiration (ET), evidenced by site-scale observations, is well
recognized as an indicator of the close interactions between carbon and
hydrologic processes in terrestrial ecosystems. However, it is not clear
whether this relationship holds at the catchment scale, and if so, what
are the controlling factors of its slope and intercept. This study
proposes and examines a generalized GPP-ET relationship at 380
near-natural catchments across various climatic and landscape conditions
in the contiguous U.S., based on monthly remote sensing-based GPP data,
vegetation phenology, and several hydrometeorological variables. We
demonstrate the validity of this GPP-ET relationship at the catchment
scale, with Pearson’s r ≥ 0.6 for 97% of the 380 catchments.
Furthermore, we propose a regionalization strategy for estimating the
slope and intercept of the generalized GPP-ET relationship at the
catchment scale by linking the parameter values a priori with
hydrometeorological data. We validate the monthly GPP predicted from the
relationship and regionalized parameters against remote-sensing based
GPP product, yielding Kling-Gupta Efficient (KGE) values ≥ 0.5 for 92%
of the catchments. Finally, we verify the relationship and its parameter
regionalization at 35 AmeriFlux sites with KGE ≥ 0.5 for 25 sites,
demonstrating that the new relationship is transferable across the site,
catchment, and regional scales. The relationship will be valuable for
diagnosing coupled water–carbon simulations in land surface and Earth
system models and constraining remote-sensing based estimation of
monthly ET.
Tropical Cyclones and Equatorial Waves in a Convection-Permitting Aquaplanet Simulation with Off-Equatorial SST Maximum
Authors: Rios-Berrios Rosimar , Davis Christopher A , Martinez Jonathan
Published: May 2023

Tropical cyclogenesis can be influenced by convectively coupled
equatorial waves; yet, existing datasets prevent a complete analysis of
the multi-scale processes governing both tropical cyclones (TCs) and
equatorial waves. This study introduces a convection-permitting
aquaplanet simulation that can be used as a laboratory to study TCs,
equatorial waves, and their interactions. The simulation was produced
with the Model for Prediction Across Scales-Atmosphere (MPAS-A) using a
variable resolution mesh with convection-permitting resolution (i.e.,
3-km cell spacing) between 10oS–30oN. The underlying sea-surface
temperature is given by a zonally symmetric profile with a peak at 10oN,
which allows for the formation of TCs. A comparison between the
simulation and satellite, reanalysis, and airborne dropsonde data is
presented to determine the realism of the simulated phenomena. The
simulation captures a realistic TC intensity distribution, including
major hurricanes, but their lifetime maximum intensities may be limited
by the stronger vertical wind shear in the simulation compared to the
observed tropical Pacific region. The simulation also captures
convectively coupled equatorial waves, including Kelvin waves and
easterly waves. Despite the idealization of the aquaplanet setup, the
simulated three-dimensional structure of both groups of waves is
consistent with their observed structure as deduced from satellite and
reanalysis data. Easterly waves, however, have peak rotation and
meridional winds at a slightly higher altitude than in the reanalysis.
Future studies may use this simulation to understand how convectively
coupled equatorial waves influence the multi-scale processes leading to
tropical cyclogenesis.
What Patients Think: A Study Examining Perceptions of Teamwork, Self-Management, and Quality of Life of Patients Diagnosed With Diabetic Foot Ulceration
Authors: Sigmon Lorie B. , Woodard Elizabeth K.
Published: May 2023

Identifying strategies to support patients diagnosed with diabetic foot ulceration (DFU) is essential to affect not only wound outcomes but also mortality and quality of life. This article reports on a cross-sectional, descriptive, correlational study of patients receiving treatment for DFU at a specialty clinic. Most participants were <60 years of age and had been diagnosed with diabetes for >5 years. Results indicated that patients with higher self-management scores reported improved general health, physical functioning, and quality of life. These findings, in a younger patient population with normal work and family obligations, suggest that interventions supporting self-management behaviors can improve physical, emotional, and general health and, ultimately, quality of life. The involvement of an interprofessional care team enhances these self-management behaviors.
Wear of Bulk-fill Composite Resins After Thermo-mechanical Loading
Authors: Alsahafi TA , Walter R , Nunes M , Sulaiman TA
Published: May 2023

Statement of Problem:

Wear of conventional composite resin presented many challenges when restoring posterior teeth and resulted in clinical complications. Bulk-fill composite resins have been proposed as a more suitable and wear-resistant alternative.

Objective:

To evaluate and compare the volumetric wear (mm3) of bulk-fill composite resins to a conventional composite resin and enamel after thermo-mechanical loading.

Methods and Materials:

Five composite resins (n=10) were evaluated: four bulk-fill composite resins (Filtek One Bulk Fill [3M Oral Care], Tetric EvoCeram Bulk Fill [Ivoclar Vivadent], Tetric PowerFill [Ivoclar Vivadent], SonicFill 3 [Kerr Corp]); and one conventional composite resin (Filtek Supreme Ultra [3M Oral Care]). Enamel from recently extracted human teeth was used as a control. Specimens were subjected to a 2-body volumetric wear evaluation using a chewing simulator (CS-4.8, Mechatronik). Disc-shaped specimens (10 mm in diameter × 3 mm in thickness) received 500,000 load cycles against steatite antagonists while simultaneously thermocycled (5000 cycles, 5-55°C). Volumetric wear (mm3) was measured using the Geomagic Control X software (3D Systems) based on digital scans of the specimens obtained before and after thermo-mechanical loading, with a Trios 3 (3Shape) digital scanner. Scanning electron microscopy analysis of wear facets and composite resin filler shape and size was performed. Volumetric wear was statistically analyzed using the one-way ANOVA and Tukey’s post-hoc test (α=0.05).

Results:

All tested composite resins wore at rates significantly higher than enamel (p<0.05). The mean volumetric wear of the composite resins ranged from 1.01 mm3 to 1.48 mm3, while enamel had a mean volumetric wear of 0.25 mm3. Bulk-fill composite resins showed higher wear resistance than the conventional composite resin (p<0.05).

Conclusions:

Bulk-fill composite resins showed higher wear resistance than the conventional composite resin, and both types of composite resin were not as wear-resistant as enamel.

Published: May 2023

Abstract. New normal is a new adaptation carried out to deal with covid-19, where people are allowed to return to their activities in the field of work while still complying with health protocols. In the new normal situation, work engagement is a challenge for all companies. The purpose of this study is to determine whether job crafting has a relationship with work engagement and to determine whether employee well-being acts as a moderator between job crafting and employee work engagement in the new normal era. This study also examines whether gender issues are present in the variables. The subjects of this study were 533 employees in Jakarta, Bogor, Depok, Tangerang, and Bekasi (Jabodetabek) Indonesia. The instruments used in this study were the Utrecht Work Engagement Scale (UWES), the Job Crafting Scale (JCS), and the Employee Well-Being Scale (EWBS). This research design was conducted in moderation using multiple sampling technique and moderated regression analysis PROCESS V4.0 Procedure for SPSS model no. 1 by Andrew F. Hayes. The results of this study indicate that job crafting is positively correlated with work engagement, and employee well-being plays a moderating role in the relationship between job crafting and work engagement. Moreover, the results of this study indicate that male and female workers have different level of engagement at work and employee well-being. This research can cover the gap in previous research so that it is expected to be a literature material for employees and companies regarding the importance of understanding the values of work engagement, job crafting, and employee well-being for the company's success.Keywords: work engagement; well-being; job crafting; employee; new normal; gender

ABSTRACT
The International Diabetes Federation (IDF) estimates that the global prevalence of diabetics will reach 578 million in 2030 and 700 million in 2045. Indonesia is ranked 7th for the country with the highest number of diabetics and is the only country in Southeast Asia included in the list. This is closely related to the high risk factors for diabetes and the lack of knowledge about diabetes prevention and control approaches. Therefore, continuous efforts are needed to provide information to the public about the prevalence of diabetes, the risk factors that trigger it, as well as efforts to prevent and control it. This activity aimed to improve public knowledge about diabetes risk factors and efforts to prevent and manage this disease. The method used was in the form of pre-test, material presentation, and post-test with the target of the activity being a group of PKK Griya Sakinah 1 Gedongan Colomadu women. The results of the analysis showed that there was an increase in knowledge before and after being given education of 72.3% with p<0.05. The conclusion of this activity is that education improves public knowledge about the prevalence, risk factors, and prevention and control of diabetes mellitus.
Logical Physics and Metaphysics of Love
Authors: Apostolov Anatoly
Published: May 2023

The 20th century gave the world two outstanding thinkers, two great Russian geniuses – Lev Platonovich Karsavin (1882–1952) and Alexander Alexandrovich Zinoviev (1922–2006). Both of them succeeded in creating their own philosophic concepts, both gave examples of brave opposition to the milieu, circumstances, terror of the authorities and remain in eternity and national history as courageous intellectuals and seekers of the Truth. Their similarity in this aspect is even more symbolic when we consider that the substance of their philosophic concepts is almost in opposition. Karsavin created his ontology as metaphysics of Love, while Zinoviev’s worldview was tragic and pessimistic. According to Karsavin the divine world is fi lled with light and Good, while Zinoviev’s world is full of darkness and Evil. Both thinkers experienced deportation from the Motherland and Karsavin perished in GULAG. The fate was more benevolent to Zinoviev – he managed to return to his Motherland to confront the Evil and protect Russia from Westernism expansion. Zinoviev’s legacy is being developed also nowadays, - in particular, this can be traced by the example of Pelevin’s futurological novels.
People on the Ruins of Humanism

Alexander Zinoviev as Soviet Traditionalist
Authors: Darenskiy Vitaliy
Published: May 2023

The article examines the phenomenon of A.A. Zinoviev as a Soviet traditionalist. In this respect, the phenomenon of A.A. Zinoviev is of interest as a paradoxical example of both radical criticism of the Soviet system and the attempts at its theoretical rehabilitation in the late, nostalgic period of A.A. Zinoviev’s life. He believed that those periods did not negate one another, but complemented each other, since they refl ected both the negative and positive sides of the Soviet period in history. But those aspects of A.A. Zinoviev are refl ected in a distorted way, since he reasoned “from within” the Soviet reality and generally shared its entire internal mythology. The phenomenon of A.A.Zinoviev in this respect is an important example of how consciousness is “reformatted” by the Soviet myth, but at the same time retains the hidden “archetypes” of Russian consciousness. The article also examines some aspects of A.A. Zinoviev’s philosophy that make his ideas related to existentialism: man as a project, the primacy of existence in relation to the essence; the imperative of becoming a person; sociality as a sphere of alienated being; the inescapable loneliness of man; God as Another and as the original model of personal being. The author distinguishes the stylistic specifi city of A.A. Zinoviev’s philosophizing and its Christian archetypes.
道咸時期嶺南詞壇之考察：以陳澧及其交遊爲中心

嶺南向來被視爲化外之地，學術風氣不盛。十九世紀初期，阮元於廣州設置學海堂，帶來江南考據學文化的同時，亦促進了廣東文化認同意識的形成。

向來論及嶺南詞多著重晚清世變與常州詞學之關聯，而少見道咸詞壇討論。本文由陳澧現存的序跋題記與詞學交遊爲考察基點，試圖廓清道咸時期嶺南詞壇之概況。首先，由於此時期的嶺南詞人先世多源出江南，加之以阮元提倡江南學術的緣故，因而嶺南繼受江南傳統頗深。陳澧等文人論詞多以浙西爲宗的審美觀即源於此。其次，學海堂文人意圖通過文史考證追溯嶺南歷史至南漢，以表出嶺南文化的悠久性與特異性的意識，同樣展現於越臺詞社的集結與《粤東詞鈔》的成書。陳澧的詞學活動和交遊亦受益於此。陳澧兼具江南與嶺南兩種文化身分，通過考察其交遊活動，不僅有助於我們理解道咸時期嶺南詞壇的審美趨向，亦能看到嶺南詞人繼受江南文化的同時，試圖建構嶺南文化主體性之過程。

Lingnan has long been seen as an uncivilized region throughout Chinese history. In the early 19th century, Ruan Yuan (1764-1849) established the Xuehai tang in Guangzhou. He introduced the theory of evidential research from the Jiangnan region, and thereby consummated the formation of the Cantonese literati’s cultural identity.

Previous research of Lingnan ci-poetry has laid more emphasis on its transitions in the late Qing dynasty than the Daoguang, Xianfeng, and Tongzhi reign-periods. This article focuses on the ci-poetry of Chen Li (1810-1882) and its peripherals to observe his social network and the development of Lingnan ci-poetry. First, it takes the perspective of cultural reception to observe that most of the Lingnan literati’s ancestors were immigrants from Jiangnan in the early to middle stages of the Qing dynasty; therefore, they succeeded not only the academic tradition of Jiangnan but also the cultural identity and literary aesthetics. This explains why Chen Li and his fellow literati took the aesthetics of the School of Western Zhejiang as an evaluation standard for ci-poetry. Second, in addition to tracing the history of Lingnan to the Southern Han Kingdom (917-971) by examination of relevant historical evidence, the Xuehai tang scholars organized poetry clubs and compiled Lingnan ci-poetry anthologies to represent the uniqueness of Lingnan culture.

The study of Chen Li, an immigrant from Jiangnan and a leader of the Xuehai tang, and his social network not only enables us to understand Lingnan ci-poetry in the mid and late Qing dynasty, but benefits us by learning a different facet of the development of the ci-poetry of the region.

"Identifying the sentiment of collected tweets has become a challenging and interesting task. In addition, mining and defining relevant features that can improve the quality of a classification system is crucial. The data modeling phase is fundamental for the whole process since it can reveal hidden information from the textual inputs. Two models are defined in the presented paper, considering Twitter-specific concepts: a hashtagbased representation and a text-based one. These models will be compared and integrated into an unsupervised system that determines groups of tweets based on sentiment labels (positive and negative). Moreover, wordembedding techniques (TF-IDF and frequency vectors) are used to convert the representations into a numeric input needed for the clustering methods. The experimental results show good values for Silhouette and Davies-Bouldin measures in the unsupervised environment. A detailed investigation is presented considering several items (dataset, clustering method, data representation, or word embeddings) for checking the best setup for increasing the quality of detecting the sentiment from Twitter’s messages. The analysis and conclusions show that the first results can be considered for more complex experiments. Keywords: Sentiment Analysis, Twitter, Data Representation, Hashtags, Clustering. "

Introduction: Data on the impact of left bundle-branch block after transcatheter aortic valve implantation (TAVI) are scarce, and treatment has been individualized. Based on this, the electrophysiological study (EPS) concomitant with TAVI may be a strategy for the early stratification of patients needing permanent pacemaker implantation (PPM). Objective: To describe the use of EPS in risk stratification of a definitive pacemaker in patients undergoing TAVI. Materials and methods: Data from seven patients with indications for TAVI due to critical aortic stenosis were retrospectively evaluated. The EPS was performed with a quadripolar diagnostic catheter in His bundle to measure the His-ventricle (HV) interval. Measurement of HV at 70 ms or above was used for discussion on PPM implant indication. Results: Four analyzed patients evolved with left bundle-branch block after TAVI. PPM implantation was indicated for one patient, and the surgery was performed uneventfully during the same hospital stay. Before TAVI, the HV interval ranged from 46 to 58 ms (mean = 53.2 ms), increasing to 52 to 84 ms (mean = 62.8 ms) immediately after valve intervention. Conclusion: The strategy of EPS during TAVI is viable to stratify patients early according to the risk of 2nd or 3rd-degree atrioventricular block, allowing adequate treatment.
Chiari-like malformation in Cavalier King Charles Spaniels impacts brainstem auditory-evoked response latency results

Published: May 2023

OBJECTIVE

To evaluate hearing loss in Cavalier King Charles Spaniels (CKCS), breed-specific brainstem auditory-evoked response (BAER) testing parameters are needed to help assess the Chiari-like malformation (CM) grade. The purpose of this study was to establish breed-specific BAER data and to determine if BAER indexes differed based on the CM grade. We hypothesized that there would be latency differences based on the CM grade.

ANIMALS

20 CKCS without apparent hearing abnormalities as assessed by the owners.

PROCEDURES

Under general anesthesia, CKCS underwent a CT scan (to assess the middle ear), BAER testing, and MRI (to assess the grade of CM).

RESULTS

No CKCS had CM0. Nine (45%) CKCS had CM1; 11 (55%) had CM2. All had at least 1 morphologic abnormality in waveforms. Absolute and interpeak latencies were reported for all CKCS and compared between CM grades. The median threshold for CKCS with CM1 was 39 and for CM2 was 46. Absolute latencies for CKCS with CM2 were consistently longer than those for CKCS with CM1 with the exception of waves II and V at 33 dB. Significant differences were found for wave V at 102 dB ( P = .04) and wave II at 74 dB (P = .008). Interpeak latency comparisons were inconsistent between CM1 and CM2.

CLINICAL RELEVANCE

Breed-specific BAER data for CKCS with CM1 and CM2 were established. The results suggest that CM impacts BAER latency results, but the influence of the malformation is not always statistically significant or predictable.

Published: May 2023

The aim of our study was to evaluate the technological (pH, water holding capacity, cooking loss, oxidation-reduction potential, water activity, color parameters, and microbiological purity) and nutritional suitability of the meat of selected lamb breeds by analyzing the indicators (fatty acid profile, fat nutritional indices, lipid oxidation, basic meat composition) that determine the quality of lipids present in the meat. A comparative analysis of meat from native Polish breeds Uhruska, Świniarka, and Wrzosówka showed that these breeds are characterized by high-quality meat. The chemical composition of meat did not significantly differ between the studied breeds. However, the fatty acid composition and atherogenicity and thrombogenicity indices of meat differed significantly between the breeds with the meat of Wrzosówka lambs having a distinct advantage and the most significant potential to protect against cardiovascular problems. Furthermore, the meat of Wrzosówka breed had color parameters that are most desired by consumers. The results presented here are of practical importance as combining meat from different breeds of lambs can allow achieving high product quality. The meat of Wrzosówka breed can be successfully used for producing such products and can serve as flagship meat for export to other European and global markets.
Multi-faceted characterization of mesenchymal stem cells and their application as a powerful tool for agrobiotechnology, assisted reproductive technologies, and veterinary and regenerative biomedicine – a review

Worldwide, microbial infections have a serious impact because they cause infectious diseases, death, and significant economic losses. Zoonosis is now a major public health issue on a global scale because of the fast expansion of human exploitation of nature and animal husbandry. Notably, in the past 30 years, over 30 novel human infections have been discovered, 75% of which fall under the category of zoonosis. Resistant strains have emerged as a result of improper use of antibiotics and insufficient infection management posing a serious risk to both public health and the global economy. As alternatives, antimicrobial peptides are showing good results. The majority of living things use antibacterial peptides (ABPs) as a key part of their natural defenses against invading infections. These peptides are cationic, amphipathic, and relatively tiny with varied sequences, structures, and lengths. For the delivery of these efficacious biological peptides, nanoparticles are providing opportunities for effective, safe, and viable delivery. An innovative method of treating infectious diseases is demonstrated by nanoparticles and antibacterial peptides. When ABPs are combined with carrier nanoparticles to optimize distribution, their half-life may be increased, allowing for lower dosages and ultimately lower toxicity. For biological applications, ABPs and nanoparticle conjugates have become effective methods, enabling the treatment, prevention of disease, and detection. More than 50 peptide medications have been made available for purchase on the market as of 2018. Around 25 billion USD is spent on peptide medications each year, including ABPs. But still, there is a gap in the distribution of these ABPs as an alternative to synthetic antibiotics. It might be due to the high cost of these goods. Thus, scientists, researchers, and commercializing companies should work together so that these ABPs with a safe delivery system should be available in the market to combat resistant strains of bacteria. In doing so, we draw attention to the significant advancements made in the field as well as the difficulties still encountered in developing imaging species, active therapies, and nano-drug delivery systems that are functionalized with peptides and proteins for clinical use.

The aim of this study was to assess the changes occurring as a result of boiling (100°C, 1 h) small brown snail (Cornu aspersum aspersum) meat in relation to its proximate composition, calcium, phosphorus and cholesterol content, as well as the profile of fatty acids and nutritional quality indices of the lipids. This species of snail was selected for research because it is currently of the greatest economic importance among edible terrestrial snails. It was hypothesized that the cooking effect may be different for foot and visceral sac. Samples for the research were collected from 6 populations bred on experimental fields of the National Research Institute of Animal Production in balice (Poland). The foot and the visceral sac, the edible parts of the snail species under investigation, were analysed separately, raw and boiled in water. The results were then compared to analogous studies carried out by other authors on beef, pork and poultry. It was found that in the visceral sac of Cornu aspersum aspersum the shares of dry matter, crude protein, fat, ash, calcium and phosphorus were greater than those in the foot (P<0.05), both in the raw and boiled material, whereas the cholesterol content was higher in the foot (P<0.05). Generally, especially in the foot, the heat treatment elevated the levels of the afore-mentioned quantities, yet the increases were not always statistically significant. Boiling the snail meat caused moderate changes in the fatty acid composition. The profile of the fatty acids and the nutritional quality indices of the foot fat were more advantageous than those in the visceral sac. In both parts of the snail carcass, the polyunsaturated fatty acids/saturated fatty acids (PUFA/SFA) ratio substantially exceeded the minimum value of 0.45 recommended by the British Department of Health. However, the n-6/n-3 ratio was too high, exceeding the maximum recommended level of 4.0 twofold and as much as threefold in the case of the foot and the visceral sac, respectively. In the foot, due to boiling, an increase of the share of sfa and monounsaturated fatty acids (MUFA) was observed, while PUFA, n-6 and n-3 decreased. In the visceral sac, the changes were less pronounced with a slight decrease of the share of sfa and PUFA, and an increase of MUFA. Therefore, in the foot, boiling worsened the PUFA/SFA ratio, the nutritive value index (NVI = (C18:0 + C18:1) / C16:0) and dietary fatty acids having a desirable neutral and hypocholesterolemic effect in humans (DFA = Σ MUFA + Σ PUFA + C18:0), but in the visceral sac these indices practically did not change. On the whole, the trends of the changes in terms of chemical composition due to boiling found in the small brown snail meat are similar to those after heat treatment of meat from popular farm animals, but the ranges of the changes differ.

In order to strengthen the applicability of data denoising algorithm, this thesis study the common telemetry data denoising algorithm based on the data of engine speed, flight space speed, cabin temperature and humidity, and establishes the evaluation model of error square sum and curve similarity to evaluate the denoising performance. Experiments show that the polynomial fitting has the greatest denoising error and slow convergence speed. The five-point cubic smoothing has the smallest overall denoising error, the median filtering algorithm can change the effect of smoothing effect by adjust it's moothing window, but ignores the authenticity of data. Therefore, the above three data denoising algorithms do not meet the requirements of telemetry data processing. In this thesis, an improved threshold function is proposed which effectively improves the data jump and excessive smoothing and reduce the denoising accuracy compared with the traditional thresholding function in order to makes the measured value closer to the true value. The algorithm is applied to the noise processing of four kinds of telemetry data, the results show that the denoising accuracy is improved significantly compared with the other three algorithms, which makes the measured value closer to the true value to reflect the changing trend of the original measurement data more truthfully, and the curve similarity is improved significantly, which are all above 80%.

Published: May 2023

In order to actively control combustion reaction, this study proposes an adaptive neuro-fuzzy (ANFIS) control scheme of interaction between premixed combustion reaction and acoustic flame perturbation where the flame pressure movement will be considered as model perturbation. Using the Cantera database, it is possible to investigate the mechanisms by which the combustion process interacts with acoustic, vorticity, and entropy waves. A well-stirred reactor (WSR) has been extensively used to model combustion processes in three different reaction zone regimes. We designed the control architecture to achieve an intelligent representation of the system for various operating scenarios, which was motivated by the complexity of the mathematical model that was being used. This goal is accomplished by an artificial bee colony (ABC), which uses simulated data from a mathematical model to optimize a neuro-fuzzy with less computational expense. The optimized neuro-fuzzy identifier is converted to an adaptive neural-based (ANFIS) controller optimized to control the outputs of the system. In keeping with the combustion temperature set point, the results demonstrate a remarkable attenuation of flame perturbation and acceptable combustion reaction quality (NOx emission).

For polymer-abrasive brush tools (PABT) working on CNC machines it is necessary to correct their wear constantly, since it is much higher compared to the wear of metal tools. Based on the dependence of tool wear on machining parameters for various materials, it is necessary to study the influence of the physical and mechanical properties of the material machined. The purpose of the paper is to study the process of finishing the surfaces of parts made of materials of different types with PABT. The analysis of dimensional wear of disc PABTs during the polishing various materials with certain physical and mechanical properties is provided in the article. The polishing was carried out in rational modes that ensure high quality and productivity of surface treatment. The similarity theory and dimensional analysis were used to assess the influence of the properties of the material machined on the intensity of PABT filament wear. To calculate it, dimensionless complexes were established, which take into account the physical and mechanical properties of the machined materials and evaluate their resistance to the penetration of abrasive grains, the ability of the material to absorb mechanical energy in the process of deformation and destruction under the impact of PABT filaments. The developed model was created for the first time. It made it possible to solve the problem of predicting the degree of dimensional wear of the disc PABT when polishing various materials, including difficult-to-machine ones. Prediction of the intensity of PABT filaments wear allows timely correction of the tool position during machining on CNC machines to ensure a constant pressing of the PABT to the surface being machined. The obtained Км material coefficient takes into account the influence of the physical and mechanical properties of the machined material and then estimates the intensity of PABT filaments wear. The KМ material coefficient can also be used to assess the PABT life and calculate the economic efficiency of the parts finishing treatment at the stage of technology development and the selection of polishing tools.
