Repensando o especismo: para além da querela entre o utilitarismo e os direitos animais
Authors: Schöpke Regina
Published: November 2023

Resumo A ideia de repensar o especismo para além da querela do utilitarismo e dos direitos animais, que invadiu a causa e gerou dissensões contínuas, tem por objetivo central mostrar que a causa animal é também, em profundidade, uma causa humana, porque a luta pelo animal passa pelo enfrentamento profundo da nossa tirania, que é a responsável por também destruir a nossa própria espécie. Este entendimento da extensão do que é a própria causa animal depende, e é isso que tencionamos mostrar aqui, de aprofundarmos mais o sentido e a direção do conceito de especismo, do psicólogo britânico Richard Ryder. Intuído como um “argumento emocional egoísta, ao invés de racional” que nos leva a crer que temos direitos legítimos de submeter todas as espécies aos nossos interesses, o conceito carecia, no entanto, de maior elaboração, de maior consistência, ou seja, precisava passar por etapas rígidas de uma construção conceitual e, isso, quem forneceu não foi o próprio Ryder, mas o filósofo australiano Peter Singer na obra pioneira, no clássico da causa, o Libertação Animal. É aqui que o conceito se torna popular e provoca mudanças muito significativas, tal como o próprio crescimento exponencial do veganismo como um modo de existir ético que diz um “não” generalizado à exploração de vidas, mas que gerou, ao mesmo tempo, desacordos por tal conceito ser ativado e se desenvolver em solo utilitarista. Decididamente, pensamos que tal querela possa vir a ser minimizada diante da percepção de que o especismo é muito mais que um preconceito que se pode vencer por humanidade e compaixão. É algo que está intrinsecamente ligado a um tipo de poder que fez emergir um tipo de homem específico (que diz respeito a todos nós que vivemos submetidos a esta estrutura de poder) que precisa ser descortinado e descontruído com a máxima urgência.

EFFECT OF VACANCIES AND VOID DEFECTS ON THE STRUCTURAL AND MECHANICAL BEHAVIOR OF TUNGSTEN UNDER HARSH TEMPERATURE AND PRESSURE CONDITIONS
Authors: Alivaliollahi A. , Alahyarizadeh Ghasem , Minuchehr A.
Published: November 2023

The body-centered cubic transition metal tungsten is frequently used as a pressure calibration material at high temperatures and pressures due to its outstanding mechanical and thermal properties. In this study, molecular dynamics simulations were performed to investigate the behavior of tungsten under harsh temperature and pressure conditions and the impact of fundamental defects, particularly vacancies, and voids, on its physical, structural, and mechanical properties through their correlation with elastic constants. The study also covers mechanical stability, elastic properties, brittleness and ductility, and hardness. The simulations utilized two different embedded atom methods and one modified embedded atom method interatomic potentials. The results show that the fundamental structural characteristics and properties of pure tungsten crystal, including lattice constant, density, cohesive and vacancy formation energies, elastic constants, and moduli in the ground state for all three potentials, are in good agreement with previous experimental and theoretical calculations and results. The calculated results demonstrate that the elastic constants-related properties for defective structures also have the same trend as the perfect crystal. The presence of defects in the crystal causes a decrease in properties at all temperatures and pressures, directly correlated to the fraction of crystal defects. As the percentage of vacancies increases, a further reduction in the elastic constants is observed. Likewise, these findings reveal that the presence of scattered vacancies in the crystal structure causes a more significant decrease in the substance's properties than a void in the center of the crystal (with the same percentage). The presence of any vacancy weakens the interatomic bonds of the atoms around the vacancy, while the existence of a void in the center has less effect on the interatomic bonds of atoms further away from the center of the crystal.
Automatic generation of high-fidelity representative volume elements and computational homogenization for the determination of thermal conductivity in foamed concretes
Authors: Fachinotti Víctor D. , Peralta Ignacio , Toro Sebastián , Storti Bruno A. , Caggiano Antonio
Published: November 2023

Foamed concretes are highly porous materials with excellent insulation properties. Their thermal conductivity is strongly dependent on the pore structure, characterized by the porosity as well as the shape and size distribution of pores. To define the representative volume element (RVE) of foamed concretes with high fidelity, we develop NRGene, an automatic generator of cubic samples with spherical air inclusions whose number and size obey a given distribution. We compute the effective thermal conductivity tensor for a given RVE using finite-element-based computational homogenization. The hi-fi RVE of foamed concretes may contain hundreds of millions of finite elements, making it better suited for benchmarking than for everyday engineering applications. Then, having the hi-fi model as benchmark, we propose a simplified model consisting of the hi-fi model called with a truncated histogram as input, which is largely cheaper while keeping a satisfactory accuracy. We model 21 different foamed concretes with a wide range of porosities and different compositions of the cement paste. Further, we demonstrate that it is the volume of all the pores of a given size, and not its quantity, what affects the effective thermal conductivity of foamed concretes.
INSTRUMENTALIZATION OF THE SUBJECT OF THE FAMINE OF 1932‒1933 IN THE REPUBLIC OF KAZAKHSTAN: FRAME ANALYSIS OF PUBLIC SPEECHES OF THE REPUBLIC'S LEADERSHIP
Authors:   National Research University “Higher School of Economics”, Varfolomeev E. A.
Published: November 2023

Using the past for political purposes is a powerful tool in the formation of identities. Post-Soviet countries demonstrate various strategies when dealing with the memory of the past. This article focuses on the political use of the topic of the famine of 1932-1933 in Kazakhstan. This topic is usually associated with Ukraine, however, starting from 2012, the famine of 1932-1933 has become one of the tools for shaping national identity in Kazakhstan. This article uses Yanow and van Hulst's dynamic frame analysis to determine the dynamics of famine framing in the speeches of Kazakhstan's presidents and their representatives. The central question of this article is how the famine of 1932-1933 is framed by the ruling elite, and what common and distinctive features can be identified through comparison with the famine framing in competing narratives. The analysis shows that the ruling elites of Kazakhstan present the famine as an artificially created tragedy without focusing on the culprit. The constructed official narrative thus differs from rival narratives in its diplomatic language. This both helps to maintain internal balance and avoids memory wars in the international arena, which distinguishes the case of Kazakhstan from the case of Ukraine.

Authors: Motrevich Vladimir , Mamyachenkov Vladimir
Published: November 2023

Based on the materials stored in the Russian State Archives of Economics of the Central Investigative Committee of the USSR, the development of animal husbandry in the individual and public sectors of agriculture of the Urals in the post-war twentieth anniversary is being investigated. The dynamics of production of four main types of livestock products (meat, milk, eggs, wool) in each of the seven studied republics and regions of the Ural Economic Region was analyzed. The influence of the state's socio-economic policy on the dynamics of livestock development in the private and public sectors of agriculture is shown. It is concluded that in the period under study, the complete socialization of the agrarian sector did not occur.
Range of Alternative Estimates of Intra-Village Income Inequality According to Western Siberian Data Tax Layouts of the Early 20th Century
Authors: Kirillov Alexey , Svirepov Alexandre
Published: November 2023

The article presents the results of the first attempt in domestic and foreign historiography to measure inequality among peasants on the eve of the Great Russian Revolution using indirect data on income from distribution sentences. At the beginning of the 20th century they were known as resolutions of village assemblies and they established the basis for the distribution of the total amount of taxes of a given village among peasants and fixed amount of payment of each individual peasant, taking into account his solvency. From a total of five thousand distribution sentences, sentences from three neighboring villages from the Tomsk district for three years from 1902 to 1908 were selected for microanalysis. The peculiarity of the distribution sentences is that they only approximately reflect the level of income of the peasant. In this regard, the authors proposed various ways to clarify the data of distributed sentences (recalculation of family data into personal data and exclusion from the calculation of the amount broken down without taking into account property criteria). The resulting figures for the Gini coefficient, which measures inequality, are compared with figures for other countries known from historiography. The authors conclude that the data support the average estimates of pre-revolutionary inequality, as opposed to the lowest and highest existing estimates, and this does not exclude the significant tension introduced into the lives of peasants by income inequality within each individual village.
The Personality of the Violator of Air Traffic and Air Transport Operations’ Safety Rules: An Integrated Portrait
Authors: Mitrofanova Alyona , Kuzakov Dmitry
Published: November 2023

There is currently no research of the personality the violator of air traffic and air transport operations’ rules (Art. 263 of the CC of the RF) that is based on actual empirical data. Such a personality description will improve the effectiveness of investigating this type of crimes and will contribute to their prevention and the prevention of air traffic accidents in general. The authors of the article studied the materials of criminal cases, reports of the Interstate Aviation Committee on the results of investigating air accidents, and specialist literature, conducted a survey of pilots and candidates who want to study this specialty, analyzed biophysiological, social-demographic, social role and moral-psychological characteristics (traits, features, connections between them) typical of the subjects of crimes under consideration. The conducted research allowed the authors to establish that a typical violator of air traffic and air transport operations’ safety rules is a male with necessary training and sufficient professional experience, having a valid certificate of an aviation specialist who passed the examination by a medical-flight expert commission. Based on the social role and moral-psychological qualities, two types of subjects of the analyzed crimes are singled out: first, aviation specialists (mostly pilots) who generally observe the requirements and never violated safety rules earlier but who, due to a number of reasons, often psychological ones (high anxiety level, lower resistance to interfe­rence, unfocused attention, tiredness, etc.) could not cope with an emergency during a flight; second, aviation specialists who intentionally violate air traffic and air transport operations’ safety rules (specifically through neglecting rules, underestimation of danger, excessive self-confidence, excessive risk-taking, etc.) as they believe that publicly dangerous consequences of their actions (inaction) will not happen or could be prevented thanks to their «flying skills», professional experience (negligent guilt is in such cases manifested by carelessness or thoughtlessness, correspondingly).
Advocating for mediation as a way to de-escalate conflict, with a focus on medico-legal claims: The anatomy of human conflict
Authors: Muller Errol C , Swanepoel Cornelis F
Published: November 2023

The incidence and extent of medico-legal claims in South Africa has increased exponentially over the past number of years. Conventionally, medical negligence claims follow the civil litigation route, while alternative, perhaps better-suited, dispute resolution techniques and mechanisms are seldom considered. Where the occasional disputant does opt for mediation instead of civil litigation, mediators are not adequately versed in the human behavioural factors of conflict, even though these are crucial in establishing an appropriate strategy to de-escalate conflict and achieve settlement. Paying particular attention to medical negligence claims, this article draws on interdisciplinary sources to propose practical guidelines for mediators, whether existing or aspirant, to develop their mediation styles and strategies with regard to the thought processes and psychological factors behind disputes. This occurs against the backdrop of the current failure by formal legal education and vocational training curriculums to equip lawyers and mediators with even a basic understanding of the anatomy of human conflict. Incorporating such teaching into our curriculums could go a long way towards greater and more effective use of mediation to settle disputes, instead of summarily opting for the adversarial, costly and time-consuming route of civil litigation.
Being (not) at home: Exiled women artists in postwar New York
Authors: Marano Virginia
Published: November 2023

In postwar art, the question of exile is the question of home. House defines a space as a locative concept. Home represents a place with a symbolic value of belonging and refers to objects, people, and ideas. Home does not designate a fixed state but rather a relational and transformative site in which individual and collective acts of remembering are embedded. In this article, the author explores the aesthetics of exile in the artistic production of exiled women artists in postwar New York, most notably Ruth Vollmer, Louise Nevelson, and Eva Hesse, who have often been excluded from the discourse around 1960s sculptural practice. The author casts the mode of construction and the viewing experience of their artworks through the notions of home and body. This contribution focuses on the intricate interrelations between women, domesticity, and artmaking associated with the aesthetics of exile and displacement, which significantly challenges any stable and absolute conception of home and place. By drawing on the works of feminist scholars and theorists, such as Sarah Ahmed, Julia Bryan-Wilson, and Iris Marion Young - in their argument that the idea of home and the practices of homemaking support relational identities-the author sheds light on how women artists in exile investigate notions of home, borders (both physical and psychological), diasporic longing, habitation, and uprootedness in a constant state of exchange.
The moral claim for obligatory dissemination of study results: part one
Authors: Motloba P , Moipolai P
Published: November 2023

The process of taking data from a person or community when doing research, and then publishing such data and one’s academic interpretation thereof in an academic journal, is usually well protected and scrutinized by several ethical checks and balances. However, to disseminate research findings back to the community in which the research was conducted is seen as a fundamental principle in ethical research practice that seldom materializes into reality. When researchers appropriately respect their obligation to do this, it is often filled with nuanced challenges. Researchers must consider how to convey complex findings in a way that is understandable and actionable for the community. Different communities have different views on norms, values and communication preferences. Researchers must be culturally sensitive in how they share findings to ensure relevance and respect. Dissemination may require resources such as translation services, community meetings or educational materials. It’s essential to share not only positive results but also negative or inconclusive findings. This avoids bias and helps the community make informed decisions.
Embracing technology for improving dental records and record keeping in the Republic of South Africa. A review.
Authors: Mahlangu NT , Chandler Susan , Sudi Stephen
Published: November 2023

Forensic odontology (FO) techniques are used to identify unknown remains and play an integral role in dental-legal cases. The utility of FO relies on accurate antemortem records – the creation and management of which continues to be a global challenge, albeit more acutely presenting in developing countries. Inadequate record keeping and management by the dental fraternity has made application of FO techniques for identifying unknown remains challenging. In addition, dental-legal cases such as in homicides, rapes, patient mismanagement and fraud are sometimes unresolved due to record keeping and health system shortcomings. This current status quo affects families and society: bereaved families are deprived of closure, and protracted litigations ensue, leading to various socioeconomic consequences.

Published: November 2023

This work is devoted to the study of the use of machine learning (ML) to predict short-circuit power consumption at the floorplan stage of the physical design of integrated circuits. The study was carried out for 4 cell groups: registers, combinational cells, sequential cells, and cells included in the clock network. An Arithmetic Logic Unit was selected and designed to create a database necessary for the training and testing of ML models. The design is carried out for various combinations of parameters. Input parameters for training models are supply voltage, temperature, clock frequency, library type based on threshold voltage, block utilization and block aspect ratio. The output parameters are the values of short-circuit power after gate level simulation, considering the parasitic parameters. In total, five algorithms were tested: Polynomial Regression, Decision Tree Regression, Random Forest Regression, Supported Vector Regression (SVR) and Multi-layer Perceptron (MLP). Root Mean Squared Error, R2 and Mean Absolute Percentage Error (MAPE) metrics were used to evaluate the performance of the models. The MLP showed the best performance, but the SVR algorithm with standardization of output parameters showed similar results with significantly less training time. The MAPE value for registers is » 0,89 %, for combinational cells » 3,19 %, for sequential cells » 2,42 % and for the clock network cells » 9,55 %. The proposed method of model training is not based on any technology-dependent data, which makes it universal for different technology nodes. The disadvantage of the method is the need for implementation of the whole design flow for a selected design with the selected range of parameters for collecting necessary training data, which requires additional time and machine resources.

The problem of multicriteria optimization of tech stack selection in a non-linear software development environment is formalized. Approaches to solving the problem based on the formation of a compromise area of local quality criteria, additive convolution of vector criteria and their scalarization are considered. An aggregate quality criterion of the software development platform is proposed. It allows taking into account the nonlinearities of the external environment in the framework of solving the problem of extremal control. The coordinates of the vector criteria are piecewise continuous functions A comparative analysis of various approaches to changing the software development tech stack in the face of significant disturbances in the development tools market has been carried out. The possibilities of boxed solutions, custom development and Open Source software development in ensuring information security of the software development environment are shown. The information stability of a software development project using Less Code tools is established and the advantages of technological solutions are shown. The analysis of the adequacy of the obtained solutions was carried out using the Open Source Less Code of the Jmix platform. The data of a comparative analysis of the budgets of the Less Code platform and custom software from vendors are given, which showed the benefits of using Open Source software development tools for long-term operation of the development platform.

Lasers are utilized in dentistry as a therapeutic tool or as an auxiliary tool. The major purpose of employing lasers in dentistry is to overcome the difficulties that are currently observed in traditional dental treatment treatments. The laser is used in hard tissue applications such as caries prevention, bleaching, restorative removal and curing, cavity preparation, dentinal hypersensitivity, growth modulation, and diagnostics, whereas soft tissue applications include wound healing, removal of hyperplastic tissue to uncover impacted or partially erupted teeth, photodynamic therapy for malignancies, and photo-stimulation of herpetic lesions. Lasers' capacity to perform minimally invasive operations with minimum patient discomfort has proven effective in the patient delivery system in dentistry practice. The availability of lasers with various wavelengths has produced a surgical panacea, and laser technology has replaced traditional surgical techniques in many oral surgical operations.
Magmatism during late Ordovician-early Silurian accretion of the Caledonides of Arctic Scandinavia: the Halti–Guolasjávri area revisited
Authors: Andréasson Per-Gunnar , Gee Davod G.
Published: November 2023

In the Scandinavian Caledonides, evidence of syn-collisional magmatism related to extensional basin development immediately prior to late Silurian Baltica–Laurentia collision was considered restricted to exotic terranes until late Silurian ages were obtained from the Halti Igneous Complex (HIC), hosted by a thrust sheet (Corrovarre Nappe, CN) of continental affinity. Various orogenic models for the extension and magmatism, a. o. subduction flip, slab roll-back, and ridge subduction have been proposed. Crucial factors include the affinity (Baltican or exotic) of the CN, and the nature of the debated unconformity at the base of the overlying exotic Vaddas Nappe (Köli). This study reexamines a critical tectonostratigraphic section and reports U–Pb zircon ages (441–436 Ma) of palingenetic granitic dykes generated by the HIC. We reinterpret the CN as a slice of the continental margin and accreted with some other nappes of the Seve Nappe Complex (SNC) which decoupled from the continent-ocean transition (COT) at an early stage of subduction of the margin. The lower part of the bipartite Vaddas Nappe, composed of a very dense dolerite dyke swarm with screens of quartzite, marble and subordinate black schist, is reinterpreted as a continuation northwards of the uppermost nappe of the SNC in Indre Troms, derived from the Ediacaran outermost continental margin. The contact with the overlying telescoped succession of conglomerates, marbles, volcanics and turbidites of the Vaddas Nappe is tentatively interpreted as a tectonised unconformity. To a classical model of back-arc spreading outboard of Laurentia during closure of the Iapetus Ocean, we add the arrival of Baltica, with a prism of decoupled slices of the COT and exhumed/exhuming UHP nappes. The spreading centre of the basin provides a plausible setting for gabbros and pillow lavas of the Vaddas Nappe, and the shores of the basin for a Seve–Köli unconformity. Future PTt studies are required in order to be able to relate the proposed shallow, syn-exhumation HIC magmatism to the tectonometamorphic evolution of the HP–UHP nappes of the SNC.
Optimization features of an aperture antenna with field variable-phase distribution
Authors: Yakimov A.N. , Bestugin A.R. , Kirshina I.A.
Published: November 2023

The solution of a number of tasks at maximum ranges in a wide sector of angles requires the use by radio engineering systems of an antenna with a quasi-sector directional pattern, the formation of which is provided by an variable-phase distribution of excitation sources (currents or fields). Taking into account the ambiguous influence of many parameters of such a distribution on the shape of the realized radiation pattern, the traditional optimization criteria for such an antenna are unacceptable. The possibilities and criteria of parametric optimization can be determined using numerical methods of mathematical modeling. In order to solve the problem of parametric optimization of an aperture microwave antenna with a quasi-sector radiation pattern and to select a criterion that allows achieving the best design solution of the projected antenna in this sense, its mathematical model has been developed. It is proposed to use a complex quality criterion for optimization in a uniform approximation of antennas with variable-phase field distribution in the aperture. The constructed mathematical model of a microwave antenna describing the quasi-sector radiation pattern and the corresponding field distribution in its aperture is presented, which makes it possible to determine the controlled parameters that ensure the achievement of a given optimization criterion. The determining influence of the fraction and amplitude of the antiphase section in the field distribution on the main parameters of the radiation pattern is shown. The results of mathematical modeling indicate the possibility of controlling the parameters of the quasi-vector radiation pattern of the aperture antenna and achieving a given criterion for its optimization. The results obtained can be recommended for practical use in the design of aperture antennas with variable-phase distribution of field.

Published: November 2023

At the moment, the actual scientific and technical task is to reduce the weight and size characteristics of the metamaterial, as well as to reduce the technological complexity of manufacturing chiral elements. This article is devoted to experimental studies of radiating structures with substrates of planar chiral metamaterial based on S-elements and gammadions, which make it possible to determine their real characteristics, as well as to verify the results obtained by electrodynamic modeling methods. The obtained results of an experimental study of the characteristics of layouts of planar chiral metamaterials based on S-elements and gammadions indicate the presence of "screen" properties in a number of frequency ranges. At the same time, the "chiral properties" of these planar metamaterials are expressed worse than those of bulk metamaterials based on spirals. These chiral metamaterials can be used in solving problems of electromagnetic compatibility of closely located radio-electronic means.
Algorithms for searching and detecting navigation signals with double meander modulation with a different number of spectral components

Published: November 2023

One of the main directions of improving the accuracy characteristics of navigation equipment of consumers of global navigation satellite systems is the use of new types of navigation signals, in particular, signals with double meander modulation. However, these signals have a relatively high level of closely spaced side lobes of the autocorrelation function, which makes it difficult to solve the problem of unambiguous measurements during search and tracking. To conduct a study of the noise immunity of algorithms for searching and detecting navigation signals by double meter modulation. Analytical expressions are obtained for calculating the total envelope at the detector output using four and two spectral components of a navigation signal with double meander modulation. It is revealed that the detection algorithm using four spectral components of a signal with double meander modulation to form the total envelope has better noise immunity than the detection algorithm using two spectral components. It is shown that the detection algorithm using two spectral signal components with double meander modulation, due to the simplicity of implementation, ensures compatibility with the existing navigation equipment of consumers of global navigation satellite systems. As a result of mathematical modeling, the dependences of the probability of the search ending with the correct detection on the signal/interference ratio are obtained. The presented research results can be used by specialists in the field of satellite radio navigation in the modernization of global navigation satellite systems, as well as in the development of advanced navigation equipment for consumers working with signals with double meander modulation.

Published: November 2023

A partir de uma visita ao centro histórico de Bauru, testemunhou-se a demolição de edificações em uma quadra próxima à histórica Estação Ferroviária Noroeste do Brasil. Essas demolições, somadas a outras que ocorreram em períodos anteriores, resultaram em um grande vazio na paisagem. Autorizada pelo poder público, essa área que já abrigou um terminal rodoviário agora está fragmentada, expondo a fragilidade da preservação do patrimônio arquitetônico, incluindo edificações tombadas pela municipalidade que compõem a mesma quadra. A discussão sobre o tombamento é crucial, uma vez que, embora seja um instrumento valioso para a salvaguarda, a conscientização histórico-cultural relacionada à preservação também é fundamental. Assim, o objetivo deste trabalho é, por meio de uma abordagem de caracterização situacional, considerar a consciência coletiva e os aspectos legais para analisar o processo ocorrido e apresentar discussões que evidenciam a vulnerabilidade de cidades de pequeno e médio porte. Nestas cidades, os recursos limitados para a preservação precisam ser melhor estudados e aplicados para manter viva a tradição arquitetônica e a herança da comunidade.

The research included estimating the elemental sulfur percentage in sulfuric foam waste, which was found to be 88.15%. Potassium polysulfide was prepared from this waste and used to prepare nano-sized sulfur particles through reduction processes. Stable suspensions were obtained for more than 30 days. The crystalline structure of the prepared samples was studied using X-ray diffraction (XRD). It showed a crystalline growth of nano-sized sulfur particles from the non-crystalline structure at a concentration of 0.5 mL. The crystalline bundles began to appear at a concentration of 1 mL, and their intensity increased, and good bundles appeared at a concentration of 1.5 mL. Scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDX) were used to study the same prepared samples, and the particle size range was (19.59-43.47 nm), (31.33-44.23 nm), and (31.52-62.64 nm). The method was characterized by its ease, low cost, and absence of harmful environmental gas emissions.

Published: November 2023

Amaç: Meckel divertikülü (MD), doğum sonrasında omfalomezenterik veya vitellin kanalın tam olmayan obliterasyonu sonucunda oluşan embriyolojik bir kalıntıdır ve gastrointestinal sistemin en sık gözlenen konjenital anomalisidir. MD genellikle asemptomatik olup; genellikle çocuk hasta popülasyonunda semptom vermektedir. Bu çalışmada; akut batının ayırıcı tanısında önemli yeri olan, preoperatif dönemde tanı konulmasının zor olduğu MD’nin güncel literatür bilgileri eşliğinde klinikopatolojik özelliklerinin analizi ve sonuçların incelenmesi amaçlandı.

Gereç ve Yöntemler: Ocak 2017 - Ocak 2023 tarihleri arasında genel cerrahi kliniğinde Meckel divertikülü tanısı alan ve ameliyat edilen hastalar retrospektif olarak tarandı. Çalışmaya 18 yaşın altındaki hastalar ve inflamatuar bağırsak hastalığı tanısı olan hastalar dahil edilmedi. Hastaların preoperatif, intraoperatif ve postoperatif verileri incelenerek analiz edildi.

Bulgular: Çalışmaya dahil edilen 22 olgunun yaş ortalaması 44,6 ± 14,6 yaş (20-74 yaş) idi. 16 olgu erkek, 6 olgu ise kadındı. Erkek/kadın oranı 2,7/1 idi. 7 olguda komorbid hastalık mevcuttu. Karın ağrısı (%72.7) en sık gözlenen semptom iken histopatolojik değerlendirmede 9 olguda heterotopik doku izlendi. Postoperatif cerrahi komplikasyon 6 hastada izlenirken en sık gözlenen komplikasyonun ileus (3 hasta) olduğu saptandı. Postoperatif süreçte bir hastada mortalite gözlendi.

Sonuç: MD akut batında ayırıcı tanıda her zaman akılda bulundurulması gereken patolojilerdendir. Tanıda gecikilmesi ve ameliyat esnasında gözden kaçması özellikle semptomatik olan hastalarda ve başka akut batın sebepleri ile ilişkilendirilebilen patolojilerde mortalite ve morbidite oranlarını artırmaktadır.
Comparison of perceived and measured accessibility between different age groups and travel modes at Greenwood Station, Perth, Australia

Although there has been a significant focus on evaluating accessibility to facilities, the differences between age groups and/or mode of access to train stations is less clear. This paper compares perceived and measured accessibility to train stations among three age groups: young adults (18-24), middle aged adults (25-59) and elderly adults (60+) and three travel modes, Park and Ride (PnR), Bus and Ride (BnR) and Walk and Ride (WnR). The study focuses on the Greenwood railway station, Perth, Australia. Measured accessibility was lower than perceived accessibility for all three age groups. Both perceived and measured accessibility to train stations were lower for the elderly than the other groups. The catchment area of elderly PnR users was also the smallest. Middle aged adults evaluated accessibility (perceived) by WnR the highest. Young adults were found to have a larger PnR catchment area than other groups. Inadequate accessibility to Greenwood Station for different age groups and by different travel modes were identified, which can be used as a decision-making aid by practitioners and station managers for improving accessibility for these cohorts. The techniques used are directly transferable to the study of other stations.
Case study on effects of the mandatory validation on bus commercial speed

The paper aims to define the new operational requirements and procedures to allow the Gruppo Torinese Trasporti (Torino public transport company) to implement mandatory validation without negative impacts on both the company and the users. To this end, a four-step methodology has been put forward: a) choice of the reference route; b) sampling plan and data collection; c) data analysis design and model specification and d) definition and analysis of future scenarios. Attained results show an increase of commercial speed from 1.5% to 14.5%, and an increase of the proportion of total dwell time on total trip time from 1 to 13 points. The most unfavourable situation for the company would be banning people from boarding the bus/tram through any door (the case today). Indeed, it would require an increase of trips in the morning peak hour in order to maintain the same time interval at bus stops. However, the impact on passengers’ travel time is non negligible since total vehicle trip time shows a rise of up to 10 minutes during weekends shifts (from 62 minutes in the current situation to 72 minutes for the worst case scenario). Thus, the present system limits the outcomes negatively for the users in terms of waiting time. However, a change could lead to such positive consequences as fuller passenger cooperation to validate tickets/passes and a more ordered boarding, thus reducing fraud and improving the image of the company.
