Published: April 2022

The cashew pseudo fruit can be used to animal feeding in tropical and subtropical countries as Brazil, Ivory Coast and Vietnam. Thus, our objective was to evaluate the intake, digestibility of nutrients and nitrogen balance of dehydrated cashew apple by-product to sheep. The experiment was carried out with 24 sheep in a completely randomized design with the treatments distributed in a 4 x 2 factorial scheme to test the inclusion (11, 21, 28 and 33% dry matter basis) and the grinding sizes (3 and 19 mm diameter) of dehydrated cashew apple by-product. To grinding sizes there was no effect to intake and digestibility, suggesting the use of dehydrated cashew apple by-product either finely or coarsely milled. The inclusion up to 33% of dehydrated cashew apple by-product inclusion did not affect voluntary intake and nitrogen balance. However, when including above 21%, there was a reduction of ether extract digestibility and more than 28% reduced dry matter and organic matter digestibility.

Published: April 2022

Knowledge about the behavior of seeds is important to support studies to minimize the effects of predatory extractivism on ornamental bromeliads. The aim of this study was to evaluate the germination, seed morphology and post-seminal development of Hohenbergia belemii and Neoregelia compacta (Bromeliaceae) in different substrates. Seeds were disinfested with a sodium hypochlorite solution and germinated in four substrates: germitest paper; washed sand; vermiculite; and the commercial substrate Plantmax®. The experimental design was completely randomized in a 2 x 4 factorial scheme, with four repetitions and 50 seeds per repetition. The seeds were sown on the substrates and stored in plastic Gerbox® boxes, which were kept in BOD chambers with 12 hours photoperiod at constant temperature of 30ºC. Data were collected daily to calculate germination percentage and growth performance. The germination started on the 4th day after sowing (DAS) for H. belemii, with stabilization on the 11th DAS, while this occurred from the 5th DAS for N. compacta with stabilization on the 21st DAS. Germination was classified as development of epigeal and cryptocotylar seedlings for both species. The vermiculite substrate had a significant effect on seed germination, GSI (germination speed index) and growth of seedlings of both species. Our findings can support future research on seed technology and also contribute to better knowledge of the evolution of morphological characters of these bromeliad species.
Experimental philosophy of memory
Authors: Michaelian Kourken , Dranseika Vilius , Álvarez Juan
Published: April 2022

Experimental philosophy is now some twenty years old and has a large body of work to its credit. Little of this work focusses directly on memory, but it has, as the philosophy of memory has come into its own over the last several years, become increasingly clear that there are numerous questions about the concept of memory to which the tools developed by experimental philosophers might profitably be applied. By describing a sample of these questions, explaining how and why they might be approached using experimental methods, and providing a snapshot of published and in-progress experimental work, this article makes a case for experimental philosophy of memory.
The feeling of familiarity
Authors: Kind Amy
Published: April 2022

The relationship between the phenomenology of imagination and the phenomenology of memory is an interestingly complicated one. On the one hand, there seem to be important similarities between the two, and there are even occasions in which we mistake an imagining for a memory or vice versa. On the other hand, there seem to be important differences between the two, and we can typically tell them apart. This paper explores various attempts to delineate a phenomenological marker differentiating imagination and memory, with a special focus on two proposed markers that have generated considerable philosophical discussion: the feeling of pastness and the feeling of familiarity. As we will find, neither of them proves to be up to the task at hand.  However, by way of a deeper exploration of the feeling of familiarity, we are able to tease out some important morals for efforts to differentiate imagination and memory on phenomenological grounds and, more generally, for efforts to engage in a descriptive phenomenological enterprise
Postmodern rendition of myth in Ashbery's ‘Syringa’
Authors: Farsi Roghayeh , Nowroozi Sima
Published: April 2022

Postmodern poetry revisits the traditions and subjects myth and history to drastic experimentations. The present paper reacts to Ashbery's postmodern rendition of the myth of Orpheus in his poem ‘Syringa’ (Ashbery, 1985). He dismantles and opposes the myth of Orpheus and Eurydice and disrupts its totalitarian voice. The main concerns of the paper are to investigate what linguistic potentials Ashbery deploys in his experimentation, how these potentials help him appropriate and then subvert the mythical subtext, and what the consequences of this subversion could be. He disturbs the myth of Orpheus by drawing on the potentials of constructed oppositions. These potentials help Ashbery deconstruct the mythical narrative and adapt it to his postmodern tastes. The theoretical framework comprises Leslie Jeffries's notion of constructed opposition. The methodology is analytic and interpretive; it conducts a close reading of the poem which situates the poem at the intersecting nodes of myth, poetry, and language. The poem is argued to have relied heavily on the oppositions that Ashbery sets up between his text and its mythical subtext. The paper concludes negation and shifts of verb-tenses are the main structural triggers of opposition along with semantic triggers.

O Gororoba e as primeiras cenas da vida proletária no Brasil
Authors: Vieira Denise Adélia , Silva Teresinha Vânia Zimbrâo da
Published: April 2022

Esse artigo pretende oferecer uma leitura do romance O Gororoba, da autoria de Lauro Palhano (1931), pseudônimo de Juvêncio Lopes da Silva Campos (1881-1947). O Gororoba, que se propõe mostrar cenas da vida proletária no Brasil, foi publicado pela primeira vez em 1931, e é ainda muito pouco conhecido tanto pelo público leitor quanto pela crítica literária. A presente leitura do livro se situa no contexto mais amplo de uma reflexão sobre literatura e política no Brasil dos anos 1930. De início, o artigo mostra a chegada ao país do romance proletário, então muito em voga no ocidente, mostra também a polêmica discussão que se seguiu sobre a sua manifestação na literatura brasileira, situando sobretudo as repercussões da publicação de O Gororoba. Em seguida, se dedica à leitura do romance, procurando mostrar algumas características que o aproximam e outras que o distanciam do gênero romance proletário. Ao mesmo tempo, o artigo defende que O Gororoba, independentemente de ser ou não um romance proletário, ao ser publicado em 1931, com certeza exibiu, para o público leitor e para a crítica literária, impactantes e desconhecidas cenas da vida proletária no Brasil, cenas que, muito provavelmente, apareciam então pela primeira vez nas páginas da literatura brasileira

Published: April 2022

The purpose of this study is to analyses the relationship between fat mass and inflammation marker, interleukin-6, clinical and metabolic data in 71 human immunodeficiency virus (HIV)-positive male patients using bivariate linear regression analyses and artificial neural network. The data used consisted of measurements collected from HIV male subjects aged 26 to 69 years, with body mass index (BMI) values between 15.47 and 36.98 kg m-2 and the fat mass values between 1.00 kg and 16.70 kg. The bivariate linear regression analyses showed that weight, waist-hip ratio, BMI, triglycerides, high-density lipoprotein and HIV viral load value were significant risk factors associated with the body fat mass in male HIV patients. Furthermore, an in-depth non-linear analysis has been performed using artificial neural network (ANN) to predict fat mass by using the significant predictors as input. ANN model with four hidden neurons obtained the highest mean predictive accuracy percentage of 85.26%. The finding of this study is able to help with the evaluation of the fat mass in the male HIV patients that consequently reflects the patients metabolic-related irregularity and immune response. It is also believed that the outcome from the analysis can help future HIV-related study on the prediction of body fat mass in male HIV patients especially in settings where dual energy X-ray absorptiometry assessments, the standard measurement method for fat mass are not available or affordable
Subjective evaluation of ﬂoor impact noise using the tapping machine and a non-standardized source
Authors: Panosso Andriele da Silva , Paul Stephan
Published: April 2022

Assessing the acoustical performance of building floor systems relies on the impact source to be utilized and on the type of floor cover used. Besides that, a reliable assessment should consider the listeners’ judgments of the sounds transmitted through floors or radiated by them. Objective ratings measured can help to foresee tenant satisfaction provided that they are well correlated with the listeners’ judgments. The main objective of this study was to compare objective and subjective evaluations, using two types of impact sources and two types of floor covers, to try and determine which objective variables could be used to predict subject evaluation and to validate the use of an alternative impact source to be used in more realistic measurements. An objective evaluation was carried out employing impact noise insulation measurements according to ISO 10140:2010, evaluating different types of floors, resilient materials, and impact sound sources (a standardized tapping machine and a calibrated tire). In the analysis of the measured samples, several parameters were evaluated according to the sound source used. Simultaneously, "sound samples" were recorded to be used in a subjective evaluation based on the judgments of 29 listeners about the Noise Annoyance and the Loudness Sensation in response to the two impact sources. The magnitude estimation method was used. Results demonstrate that tapping machine measurements correlate very well with the subjective evaluation measurements and the calibrated tire presents well-correlated results in a specific measurement set-up. In addition, linear regression analysis of the objective and subjective variables shows alternative single number quantities for ratings of impact noise insulation
An In Situ Mock Code Program in the Pediatric Intensive Care Unit: A Multimodal Nurse-Led Quality Improvement Initiative
Authors: Hammontree Jennifer , Kinderknecht Catherine Glenn
Published: April 2022

Background

Lifesaving resuscitation is required for approximately 1 in 100 patients in the pediatric intensive care unit. Certification renewal alone is insufficient to guarantee adequate knowledge, skills, and confidence among staff members involved in infrequent resuscitation events.

Local Problem

Knowledge and skill gaps were identified in pediatric intensive care unit staff members involved in patient resuscitation events. The primary aim of this quality improvement project was to optimize patient resuscitations through improved staff performance and coordination between interdisciplinary roles.

Methods

A multidisciplinary committee was created to develop, implement, and evaluate a mock code program. Surveys were administered before and after the intervention to assess self-perceived resuscitation performance and program effectiveness. Code sheets were analyzed for documentation quality and adherence to pediatric advanced life support guidelines. The committee used a multimodal approach to education, including high-and low-fidelity in situ mock code simulations and supplemental educational events.

Results

From September 2018 through January 2020, the committee conducted 65 events for almost 500 participants. Nurses’ levels of self-reported confidence in initiating pediatric advanced life support interventions and identifying cardiac rhythms increased, as did perceived level of competence and knowledge. Most unit staff members considered the mock code program to be “very to extremely effective” in increasing resuscitation competence, confidence, communication, teamwork, and role clarity. Adherence to recommended resuscitation behaviors improved, as did code sheet documentation quality.

Conclusion

An in situ mock code program using a multimodal approach to education can be a successful educational adjunct to biennial pediatric advanced life support certification.
Infezione da HIV e segretezza professionale
Authors: Boroni Valentina
Published: April 2022

La tutela del diritto alla riservatezza vive un momento cruciale nel caso dell'infezione da HIV, ove i diritti alla tutela dell'intimità del singolo spesso si pongono in contrasto con le esigenze di tutela della salute dei terzi. Nel presente lavoro viene motivata e discussa la posizione etica che privilegia un'accezione relativa del segreto professionale e le differenti posizioni assunte dalle norme deontologiche italiane ed americane in proposito. Particolare attenzione viene poi dedicata alla tutela giuridica del diritto alla riservatezza nel contesto normativa italiano nell'ambito del quale, se da un lato vige di regola il divieto di rivelare, si distinguono casi in cui il medico deve comunicare il segreto e quelli in cui può comunicarlo.

Individualized Medical Nutrition Therapy for Diabetic Patients according to Diabetes Medication
Authors: Park Juyeon
Published: April 2022

Medical nutrition therapy (MNT) plays an important role in diabetes management. For effective MNT, not only an individualized meal plan considering daily eating habits and preferences, but also overall management strategies and adjustments on drug therapy and physical activity are required. In particular, an individualized meal plan is needed based on an understanding of the medicine’s mechanism and side effects, because glucose is controlled well only when prescription medicines and diet are in harmony.
Microbiome and Diabetes
Authors: Kim Jin Hwa
Published: April 2022

The prevalence of metabolic diseases such as obesity, type 2 diabetes, and insulin resistance continues to rise. These conditions are associated with multiple social, genetic, and environmental risk factors, including the human gut microbiota, which has emerged as a critical mediator linked to metabolic disease. Recent evidence suggests that the gut microbiota has personalized effects on the gut–brain axis, which controls metabolic function. Gut microbiota can be a great source of prognostic biomarkers and therapies for metabolic diseases. The microbiome also influences immune system development and homeostasis. In this review, I summarize recent findings regarding the association between the gut microbiome and type 2 diabetes. These findings will inform future diabetes mellitus prevention, diagnosis, and treatment strategies.

Purpose:

An indolent nature, with a high risk of local recurrence along with the potential for distant metastases, makes the relatively rare adenoid cystic carcinomas (ACCs) of the head-and-neck region, a unique entity. In the base of skull (BOS) region, these cancers require radiation doses as high as 70–72 GyE in proximity to critical structures. Proton therapy (PT) confers physical and radiobiological advantages and local control at 2–5 years exceeding 80% in most series, compared with below 60% with photon-based techniques. We report a case series of ACCs of the BOS, treated with image-guided, intensity-modulated PT (IMPT).

Materials and Methods:

During 2019–2020, we treated six patients with skull-base ACC IMPT with on-board, cross-sectional image guidance. Dosimetric data, toxicity, and early outcomes were studied, and a comparative review of literature was done.

Results:

Three patients underwent PT/proton–photon treatment for residual/inoperable lesions and three patients underwent reirradiation for recurrent lesions. The prescription was 70 GyE in 31–35 fractions, and 95% of the clinical target volume (CTV) received 98% of the prescribed dose in five of the six patients. Grade 3 mucositis and skin reactions were noted in two patients and one patient, respectively. Five of the six patients were controlled locally at a median follow-up of 15 months.

Conclusion:

The radiobiological and physical characteristics of PT help to deliver high doses with excellent CTV coverage in skull-base ACCs, adjacent to critical neurological structures.
Thermophysical behavior of mercury-lead liquid alloy
Authors: Panthi Narayan , Bhandari Indra , Koirala Ishwar
Published: April 2022

Thermophysical properties of compound forming binary liquid mercury-lead alloy at temperature 600 K have been reported as a function of concentration by considering HgPb2 complex using different modelling equations. The thermodynamic properties such as the Gibbs free energy, enthalpy of mixing, chemical activity of each component, and microscopic properties such as concentration fluctuation in long-wavelength limit and Warren-Cowley short range order parameter of the alloy are studied by quasi-chemical approximation. This research paper places additional emphasis on the interaction energy parameters between the atoms of the alloy. The theoretical and experimental data are compared to determine the model’s validity. Compound formation model, statistical mechanical technique, and improved derivation of the Butler equation have all been used to investigate surface tension. The alloy’s viscosity is investigated using the Kozlov-Ronanov-Petrov equation, the Kaptay equation, and the Budai-Benko-Kaptay model. The study depicts a weak interaction of the alloy, and the theoretical thermodynamic data derived at 600 K are in good agreement with the experimental results. The surface tension is slightly different in the compound formation model than in the statistical mechanical approach and the Butler equation at greater bulk concentrations of lead. The estimated viscosities in each of the three models are substantially identical.
Karta z dziejów historiografii ruchu robotniczego: przypadek Jerzego Targalskiego (1929–1977)

A Page from the Historiography of the Workers’ Movement: the Case of Jerzy Targalski (1929–1977)

The article is devoted to Jerzy Targalski (1929–1977), a historian of the workers’ movement and the beginnings of socialist organizations in Poland. Targalski’s intellectual biography draws attention to the previously neglected area of studies on the history of historical science, such as the party structures of science, namely the Institute for Education of Scientific Staff/ Institute of Social Sciences at the Central Committee of the Polish United Workers’ Party and the Department of Party History at the Central Committee of the Polish United Workers’ Party. What seems to be an important theme is the development of Targalski’s research interests and the evolution of his critical approach to both the historiography and the reality of the Polish People’s Republic.
O zaangażowaniu Kierownictwa Badań nad Początkami Państwa Polskiego (1949–1953) w badania ratownicze na terenie Nowej Huty

On the Involvement of the Department for Studies on the Origins of the Polish State (1949–1953) in Rescue Excavation Research in Nowa Huta

The Department for Studies on the Origins of the Polish State was an institution established in 1949 by the Ministry of Culture and Art to carry out interdisciplinary research (which began a year earlier) on the genesis and functioning of the state of the First Piasts, undertaken in connection with the 1000th anniversary of the foundation of the Polish state and its baptism (1966). Although the Department’s main goal was to identify the main centers of the early Piast state, it also had its merits in the field of monument protection – archaeologists, taking advantage of the unique situation of destruction and demolition, entered the historic downtowns and began their research. The scale of the necessary interventions was becoming embarrassing, especially since the so-called great buildings of socialism and the reconstruction of cities led to numerous discoveries. However, the most challenging situation was at the construction site of Nowa Huta, which was located for political reasons, without considering that the selected areas were covered with fertile soil used by the population since the Neolithic. This article aims to present the history of rescue excavations in the area of Nowa Huta (now a district of Krakow, established in the late 1940s), the first stage of which was carried out as part of the Department activities.
Metabolism testing methods as exemplified by selected new psychoactive substances (NPSs)
Authors: Piechaczek Małgorzata , Smolik Magdalena , Rojek Sebastian , Bystrowska Beata
Published: April 2022

Detailed assessment of the biotransformation of compounds and the activity of their metabolites is an extremely important element in the safety evaluation of a substance, both in preclinical and clinical studies. It should be noted that the metabolite may differ from the parent compound in terms of physicochemical properties and consequently pharmacological and toxicological properties.

The purpose of the biotransformation of xenobiotics is to increase their hydrophilicity, which allows excretion in the urine. the metabolites of biotransformation phase I show undesirable pharmacological or toxic effects much more often. according to U.S. Food and Drug administration (FDA) guidance, if a metabolite in the human body accounts for more than 10% of the total amount of metabolites, its safety should be thoroughly assessed. Metabolites can interact more strongly or weakly, or to the same degree, with the same or a different molecular target as the parent compound. they can also display non-specific effects by, for example, damaging macromolecules (e.g. proteins, nucleic acids) in the way that free radicals do. In the case of new psychoactive substances (NPSs), the pharmacological properties, including metabolism, are largely unknown until they are traded illegally and their users begin to appear in departments of toxicology or forensic medicine. It is in this way that the activity profile and probable metabolic pathways of NPSs are determined. to determine the metabolites of NPSs is also an important toxicological skill in the forensic testing of biological samples (blood/urine/tissue) collected from victims, in which metabolites, not parent compounds, are usually found.

Using examples from the authors’ research and the available literature, the article aims to present alternative methods of metabolism testing for NPSs. In vitro methods (application of microsomes, S9 fraction, hepatocytes, cytosol) are discussed and comparisons are made between the results of in vivo tests on animals and analyses of autopsy material.

The experiments and the literature review demonstrate that by using in vitro methods the metabolism of NPSs can be predicted with high probability. By improving existing methods of metabolism research and creating new and alternative ones it will be possible to better understand metabolic pathways and better identify the NPS metabolites formed in the human body. This will contribute not only to the development of better methods of treating NPS poisoning, but will also be of use when compiling forensic and medical reports for the judiciary.
Losy zakonników i zakonnic z klasztorów skasowanych w Wielkim Księstwie Poznańskim (do 1841 r.)
Authors: Włodarczyk Zdzisław
Published: April 2022

Na mocy postanowień kongresu wiedeńskiego zachodnie tereny Księstwa Warszawskiego z Poznaniem i Bydgoszczą włączono do monarchii pruskiej jako Wielkie Księstwo Poznań- skie / Prowincja Poznańska. Nowy władca — Fryderyk Wilhelm III — zapewniał wprawdzie poszanowanie religii katolickiej wyznawanej przez większość mieszkańców, nie dotyczyło to jednak wspólnot zakonnych (57 domów, 454 zakonników i 119 zakonnic), których liczbę postanowiono sukcesywnie zmniejszać, z czasem zaś zlikwidować. Okoliczności nie pozwalały przy tym na wykorzystanie radykalnych wzorów śląskich z 1810 r. Władze pruskie postanowiły dokonać likwidacji przez stopniową redukcję stanów osobowych, m.in. drogą naturalną, za sprawą likwidacji nowicjatu czy wreszcie sekularyzacji. Procesy te uległy przyspieszeniu po wybuchu powstania listopadowego i mianowaniu naczelnym prezesem Eduarda Flottwella. Rozkaz gabinetowy z 31 marca 1833 r. nakazywał likwidację, w okresie trzech lat, pozostałych jeszcze na terenie Księstwa zgromadzeń. Ostatecznie, w roku 1841, stanowiącym cezurę końcową, zmarł ostatni komisarz reformacki, niedługo potem dokonano kasaty klasztoru bernardynów w G órce pod Łobżenicą. Na terenie Księstwa pozostały tylko domy: szarytek w Poznaniu i filipinów w G ostyniu — uznane przez pruskich decydentów za użyteczne. The history of monks and nuns from dissolved monasteries and convents in the Grand Duchy of Posen (until 1841) Pursuant to the decisions of the Congress of Vienna, western parts of the Duchy of Warsaw (with Poznań and Bydgoszcz) were incorporated into the Kingdom of Prussia as the Grand Duchy of Posen/the Province of Posen. Although the new ruler, Frederick William III , guaranteed tolerance for the Catholic religion practiced by most of the region’s inhabitants, this did not extend to monasteries and convents (a total of 57 sites with 454 monks and 119 nuns). These were to be gradually reduced in number, and ultimately — dissolved altogether. At the same time, circumstances did not allow for radical solutions of the kind adopted in Silesia in 1810. The plan of Prussian authorities involved a “natural” dissolution of monasteries and convents through a gradual reduction in the numbers of monks and nuns (for example by eliminating novitiate) and secularization. The implementation of these solutions accelerated after the outbreak of the November Uprising, and the subsequent designation of Eduard Flottwell as the governor. Under an administrative decision of March 31, 1833, the remaining congregations in the Grand Duchy were to be completely dissolved within 3 years. The process ultimately ended in 1841 with the death of the last reformation commissioner, and the dissolution of the Bernardine monastery in Górka (near Łobżenica) soon after. The only congregations left in the territory of the Duchy were the Daughters of Charity of Saint Vincent de Paul in Poznań and the Congregation of the Oratory of Saint Philip Neri in Gostyń, as the Prussian authorities considered them useful.
Młodzież przeciwko zniewoleniu. Opór społeczny i działalność konspiracyjna wśród młodzieży szkolnej w okresie stalinowskim w świetle wybranych przykładów z różnych części Wielkopolski
Authors: Bereszyński Zbigniew
Published: April 2022

W latach 1946–1947 komuniści stopniowo rozprawili się z legalną opozycją polityczną spod znaku Polskiego Stronnictwa Ludowego. Ogłoszona w ślad za tym amnestia okazała się druzgocącym ciosem dla podziemia kontynuującego działalność z okresu drugiej wojny światowej. W tej sytuacji szczególnego znaczenia zaczęła nabierać opozycyjna działalność wśród młodzieży dorastającej już w okresie powojennym. Postępująca sowietyzacja życia społecznego w Polsce spotykała się z rozmaitymi przejawami sprzeciwu i oporu w tych środowiskach. Konsekwencją tego były podejmowane spontanicznie próby działalności konspiracyjnej wśród młodzieży szkolnej. Inicjatywy takie rodziły się również na terenie Wielkopolski. Nie stanowiły one poważnego zagrożenia dla systemu komunistycznego, ale ówczesny aparat władzy bynajmniej ich nie lekceważył, a skutkiem tego były działania represyjne z jego strony. Problematykę tę przedstawiono w artykule z wykorzystaniem wybranych przykładów z różnych części regionu.

Youth against oppression. Social resistance and underground activities among school youth in the Stalinist period as exemplified by cases from various parts of Greater Poland

In the years 1946–1947, the communist authorities gradually eliminated their legal political opposition gathered in the Polish People’s Party. The amnesty that followed turned out to be a deadly blow to the so-called underground state, whose members continued their activity after the Second World War. Under these circumstances, the opposition of youth, growing up in post-war Poland, gradually gained in significance. The progressing Sovietization of social life in Poland was met with various forms of opposition and resistance in these circles, and prompted spontaneous acts of conspiracy among school-goers. Such initiatives were also born in Greater Poland. They did not pose any real threat for the communist state, but the authorities treated them seriously and responded with acts of repression. This is discussed in the present paper, based on examples from various parts of the region.

Kalkanlı Dağlarında Kar Yaması Erozyonu İle Oluşan Nivasyon Oyukları
Authors: TUROĞLU Hüseyin
Published: April 2022

Nivasyon oyukları, kar yaması erozyonu ile oluşan bir aşınım şeklidir. Bu aşınma; kar yamaları altında, detritik nitelikteki zeminin sığ üst zonunda meydana gelen donma-çözülme döngü süreci ile gerçekleşir. Nivasyon süreci olarak tanımlanan bu aşınma; iklim, jeomorfoloji, zeminin tekstür ve strüktür özellikleri ile bitki örtüsü özelliklerinin kontrolünde gelişir. Kar yaması; hem sıcaklığın gün içinde donma ve çözülme döngüsü içinde değişmesi için termal koruyuculuk yaparak, hem de nivasyon sürecinin çalışması için gerekli olan suyun teminine katkı yaparak aşınmanın yıl içindeki etki süresi ve şiddeti üzerinde önemli rol oynar. Bu çalışmada; nivasyon oyukları ele alınarak, Kalkanlı Dağları’ndan (Trabzon, Gümüşhane) kaynağını alan Yanbolu Deresi yukarı çığırı 2000-2200m yükselti kademesindeki nivasyon oyukları örneklemelerinde onların oluşum ve gelişimlerinin açıklanması amaçlanmıştır. Araştırma kapsamında; yüzey analizleri için 1m yersel çözünürlükteki topografik veritabanı drone verisinden üretilmiştir. Çalışma sahasının nivasyon koşullarının değerlendirilmesi amacıyla; Meteoroloji Genel Müdürlüğü’nden temin edilen, 2050m yükseklikteki Torul/Zigana Kayak Merkezi (İstasyon no: 17696) meteoroloji istasyonu iklim verileri kullanılmıştır. Yüzey analizleri için ArcMap 10.7 yazılımı tercih edilmiştir. Arazi çalışmasında nivasyon oyukları incelenerek, ölçümler Garmin Etrex 10 El Tipi GPS ile gerçekleştirilmiştir. Ayrıca Google Earth görüntülerinden de faydalanılmıştır. Nivasyon oyuklarının oluşum ve gelişimlerine ait daha önceki araştırmaların bulgu ve sonuçları; araştırma sahasındaki örnekler ile karşılaştırmalı olarak değerlendirilmiştir. Nivasyon gelişiminin güncel bir jeomorfolojik süreç olması nedeni ile sahanın güncel iklim özellikleri dikkate alınarak, nivasyon süreci perspektifinde değerlendirilmiştir. İklim verilerinin nivasyon sürecinin aktif olmasını desteklediği görülmüştür. Arazi çalışmaları ile elde edilen sahanın jeomorfolojik özellikleri, zeminin tekstür ve strüktür özellikleri, orman örtüsünden yoksun alpin çayır katı hakkındaki bulgular; 2000-2200m yükselti kademesinde halen kar yaması erozyonunun devam ettiğine işaret etmektedir. Arazi çalışmasında, nivasyon oyuklarının enine, boyuna ve dairesel türleri tespit edilmiş olup, bunlar karakteristik özelliklerine göre başlangıç, gençlik ve olgunluk gelişim aşamaları şeklinde sınıflandırılmıştır. Sahada gözlenen nivasyon oyukları genellikle başlangıç ve gençlik gelişim aşamalarında olduğu anlaşılmaktadır. Sahada görülen olgunluk gelişim aşamasındaki dairesel nivasyon oyuğu; Dipsizgöl nivasyon sirki’dir. Nivasyon sirk göllerin ideal bir proksi kapanı olduğunu ve geçmişin coğrafi arşivini sakladıklarını, Dipsizgöl tabanına ait kurtarılmış sedimentlerinin analizleri doğrulamıştır. Bu bilimsel öneminin yanı sıra nivasyon sirk göllerinin korunması gereken birer doğal miras olduğu da kabul edilmelidir.

Authors: Giorgio Agostino , Paris Francesco
Published: April 2022

The widespread use of Field Programmable Gate Array (FPGA) in the consumer electronics market makes designers integrate more and more solutions with these programmable logic devices. In this paper, the authors use a CYCLONE V 5CSEMA5FC31C6N Altera-Intel FPGA in order to implement a UART-to-Bell202 converter for the direct interfacing of an FPGA with an analogue line on the voice band, not still available for industrial and consumer electronic for communications applications. In particular, a transmitter is created with an Audio Shift Keying modulation without phase continuity, capable of converting UART signals coming from any UART transmitter (for example a personal computer, PC) into a modulated signal. The design has been performed using the Terasic DE1-SoC development board, while instrumental tests have been performed with a ZEROPLUS LAP-C logic states analyzer and a CML1102 oscilloscope..

Authors: Minh Tuan Ngo , . Vihoang
Published: April 2022

Nanofluids made by mixing the nanoparticles with the cutting fluid can be applied in the machining process to reduce the tool wear and the surface roughness. The Taguchi method based on the grey relational analysis theory was selected to optimize multi-responses for the groove milling process using nanofluids as the tool wear and the surface roughness. The grey relational index (GRI) were determined from the experimental results (the tool wear and the surface roughness) by using the grey relational analysis theory. Then the optimal condition – (the nanoparticle concentration 0.2% and the cutting speed 25mpm) was determined by Taguchi’s method through the mean value and ratio (S/N)..

The Burr Type X distribution is considered as a probability model for the lifetime of the product. Sampling plans in which items that are put to test, to collect the life of the items in order to decide upon accepting or rejecting a submitted lot, are called reliability test plans. A test plan to determine the termination time of the experiment for a given sample size, producer’s risk and termination number is constructed. The preferability of the present test plan over similar plans exists in the literature is established with respect to time of the experiment. Results are illustrated by an example.
Determining Optimum Number of Flight Deck Crew from HR Perspective
Authors: Abdullah Nour Eng. Muhammad bin , Taylan Osman
Published: April 2022

Airline companies are usually facing high flight deck crew (FDC) costs. They usually go through three different stages just to determine the FDC. First is the network and scheduling which translates customer demand into flying hours. Second, the manpower planning which convert flying hours in terms of FDC. The third is the crew scheduling, which is pairing, assignment, and recovery from irregular operations. This study aims to focus on helping the manpower planning department in an airlines company to find out the availability of new methods for determining the optimum FDC with minimum possible cost. One important function of HR is the Strategic Workforce Planning (SWP). In other words, the succession planning. SWP focuses on two types of positions; the critical, and the pivotal. Since FDC positions (Captains and First Officers) are very critical, so they are the most important positions in any aviation -airline- company. Three new theories have been developed and proposed in the literature. The results and findings showed that two of the three theories give better results, an airline company can save up to 75 million $ per annum.

Swarm robotics is a method of collective robotics that has received a great deal of attention in recent years. Swarm robotics ambitions at growing structures that are robust, scalable and flexible. The literature is being analyzed from the swarm engineering perspective. We proposed taxonomies to research the swarm robotics literature: the techniques taxonomy, wherein we discussed the principle layout and analysis methods, etc. In this paper, we supplied a review of the state of the art in swarm robotics from a swarm engineering perspective. We foresee that, as swarm robotics is further advanced and as it is used to address real-world applications, the need for a swarm engineering will increase. In the conclusions, we additionally diagnosed a few open issues along with swarm engineering aspects at underdeveloped level.

Authors: Khan Muhammad Asghar , Akhtar Rehman , Babar Abdur Rehman
Published: April 2022

The manufacturing process of High-Pressure Laminates was investigated using a strong optimization tool, the Taguchi method. High pressure laminates consist of various types. Each type has specific manufacturing process and uses. One of the utmost and crucial types of High-Pressure Laminate is Electrical Bakelite Sheet or industrial grade sheet. Electrical Bakelite Sheet is mainly used in Transformer as an insulated material. The Taguchi method was used to enhance the quality of the product and optimized the manufacturing process of Electrical Bakelite Sheet. Baking Time, Temperature, Resin Content, Pressure and Volatile Content are factors of industrial grade sheet manufacturing process and responses of these factors are electrical Insulation and thickness. Optimal value of these factors for the process are obtained through Taguchi method and found experimentally. As a result, the Taguchi technique is used to explore the effects of various electrical Bakelite Sheet parameters on responses such as electrical insulation and thickness. Pressure, Temperature, Volatile Content, Resin Content, and Baking Time are the factors which should be considered for the experiment. The Taguchi L27 orthogonal array is used for testing. The significant factors for responses of the electrical Bakelite Sheet are identified using analysis of variance (ANOVA). Determination of the significant factors value resulted in best achieving yield of the product.

Authors: Sasikala Visalakshy , Sankaranarayanan Venkataraman
Published: April 2022

We explore how diversity plays out in a historically male-dominated domain of international business – mining – by analyzing the diversity statements and initiatives reported by 25 of the top 50 global mining firms in terms of market value. We find that home country organizational field configurations play a pivotal role in determining how mining firms perceive diversity and the specific diversity dimensions they focus on. We distinguish between accommodative, defensive and reactive configurations to understand regional variation in the way mining firms manage diversity. We provide actionable recommendations to key stakeholders on adopting a proactive approach towards advancing diversity.

Autonomous cars represent the future of human transportation. We contribute to this course by cooperation with the automotive industry on making a Porsche Panamera car drive autonomously. Unfortunately, performing experiments with real cars is expensive, potentially dangerous, and sometimes not convenient. For this reason, we prototype many of the algorithms for the Panamera on an RC-car (a scaled-down model of autonomous car), which makes many experiments easier to conduct. To validate our work and to compare it with others, we participate in the International F1/10 Autonomous Racing Competition. In this racing event, student teams from all over the world compete in a so-called battle of algorithms. When developing these algorithms or combining a few of them in more complex control approaches, it is not always easy to decide which approach is better. In this paper, we present a comprehensive methodology for comparing the control approaches. We selected the algorithms for the comparison from the list of state-of-the-art approaches as well as approaches used by the teams within the competition. The compared algorithms include: - Iterative Follow The Gap algorithm, - Iterative Follow The Gap algorithm extended with location-based information (Map-based Follow The Gap), and - Static Optimal Trajectory Tracking algorithm. We compare the approaches above directly on the platform used in the competition rather than in simulations. Our evaluation is supported by a high-precision external localization system. We use the comparison criteria, selected based on our years-long experience, and which have proven themselves essential for successful participation in the competition. The criteria are: - racing performance (i.e., how fast is the car able to drive through the track), - obstacle avoidance slowdown (i.e., how much is the performance of the approach penalized by the presence of static obstacles), - hardware load (computing resources on the platform are limited; as the platform is selected by the organizers of the event), and - configuration effort (i.e., how much effort does it take to tune the parameters of the approach). The results of this paper will serve as a baseline for assessing the performance of control approaches developed in the future.

Published: April 2022

This paper describes an entire automated vehicle platform for software prototyping and demonstration. The project is build up with the cooperation of the Czech Technical University and Porsche Engineering Services company. The platform is based on a serial production car Porsche Panamera. The aim of this prototype is to close perception - planning - control loop and demonstrate it at a fully automated slalom ride. Besides the sensors already available in the stock Porsche Panamera car, our system is equipped with differential GPS, mono camera, and 16-layers LiDAR. The algorithms run on the NVIDIA TX2 platform, are integrated using Robotic Operating System (ROS) middleware and interface with the car ECUs via CAN and FlexRay buses. A Support Vector Machine with Histogram of Oriented Gradients (HoG) feature vectors from the camera image is used for cones classification. Cone localization is done relative to the car. It uses data from the camera and LiDAR. A Kalman filter derives accurate car odometry. It takes data from the GPS, car builtin accelerometer and actual speed and steers commands. The bicycle kinematic model is used to interconnect all of these pieces of information and for Kalman filter implementation. Clustering and filtering of all detected cones generate the cone map. Optimal trajectory planning respecting the car kinematics is crucial for the smooth slalom ride between the cones. A nonlinear quadratic optimization problem for this purpose is formulated and solved based on the bicycle model. Finally, the trajectory tracking control keeps the car on the planned slalom trajectory during the ride. Substantial work was devoted to experiments with a real vehicle and the fine - tuning of the system parameters. Validation of the system reveals interesting observations related to the precision, frequency and sensitivity of the system components and usability of ROS middleware for the autonomous driving tasks.
