Iron and steel workers acquiring a factory in exchange for a single coin: a genuine people’s sector

ABSTRACT The iron and steel industry, a cornerstone of industrialization, is vital for economic growth and infrastructure development, particularly in Turkey, where it has been central to industrial policy. This study explores how the Karabük Iron and Steel Factories, known as ‘the factory of factories,’ were transferred to workers for a symbolic price of 1 Turkish Lira (TL) following worker protests against privatization. The study focuses on the strong labor movement and social cohesion among the iron and steel workforce, using the 8 November 1994, protests as a case study. It evaluates how the structural characteristics, societal concerns, and outcomes of these protests differ from other labor movements. By highlighting these differences, the study aims to contribute to the literature on labor movements and protest dynamics. The November 8 protests were significant in raising awareness of workers’ rights and union struggles through media and public attention, while also shedding light on the state and public authorities’ strategies for maintaining social order. Moreover, the study links the achievements of these protests to the concept of the people’s sector. One key conclusion is the relationship between the iron and steel sector and the people’s sector, emphasizing the role iron and steel workers have played in fostering social stability and solidarity.

Realizing extraordinary bifunctional electrocatalytic performance of layered perovskite through Ba-site Gd doping toward oxygen reduction and evolution reactions

Herein, we propose a Ba-site Gd doping protocol in layered perovskites, demonstrating highly active bifunctional PrBa1-xGdxCo2O5+δ electrocatalysts toward oxygen reduction reaction (ORR) and oxygen evolution reaction (OER). Benefiting from enhanced oxygen surface exchange and chemical diffusion kinetics, resultant PrBa0.95Gd0.05Co2O5+δ (PBG0.05CO) exhibits an area-specific resistance (ASR) of 0.038 Ω cm2 at 700 °C, reduced by ∼46.5% relative to undoped PrBaCo2O5+δ (PBCO). When evaluated as the air electrode, the as-fabricated single coin fuel cell delivers a peak power density (PPD) of 1230 mW/cm2 at 700 °C. For the CO2-electrolysis at 750 °C, the large current density (J) of 2630 mA/cm2 is achieved in the PBG0.05CO anode-based electrolysis cell at a voltage (V) of 1.8 V. Furthermore, exceptional operating stability is realized in both ORR and OER manners. Our findings highlight an effective strategy to optimize the electrocatalytic properties of layered perovskites, endowing potential applications in energy storage and conversion aspects.

Exploring Humanity Versus Nature in the Writings of Robert Frost and Ghani Khan: An Ecocritical Analysis

The current study examines human beings versus nature in Robert Frost's and Ghani Khan's writings. Frost's contribution to nature is from English literature, whereas, Ghani Khan's anthology is an exceptional appreciation of nature from Pashto literature. Both of the literary figures illustrate nature and human's treatment of nature. Ecocriticism is used as a lens to analyze the writings of Robert Frost and Ghani Khan. Ghani Khan is labelled as a mad philosopher due to his unconventional writing style, perception of nature, and exotic expression of love. The enchanting beauty of nature and its mysterious hazards are different sides of a single coin in Frost's writings. Nature has prime importance in both of the glaring literary figures from America and Pakistan.

Double coin ingestion in a child: a rare occurrence

Foreign bodies in the esophagus pose a common ENT emergency, often involving a single coin that typically passes without harm. However, the occurrence of paired coin foreign bodies is exceptionally rare. A notable case involves a 3-year-old child who presented to the ENT emergency department with sudden dysphagia and vomiting. A plain X-ray of the soft tissue in the neck and chest revealed a unique finding-a double circular opacity in the cervical esophagus, indicating the ingestion of two foreign bodies in perfect radiological alignment. Given the rarity of such cases, coupled with the challenges in diagnosis when a comprehensive history is unavailable, this instance stands out. The child underwent a rigid esophagoscopy under general anesthesia to address the situation. This case underscores the importance of considering uncommon scenarios in clinical practice and the necessity for thorough diagnostic approaches, especially in the absence of a detailed patient history. The presentation of dual foreign bodies in precise radiological alignment adds a layer of complexity to the diagnosis, highlighting the need for a nuanced and vigilant approach in managing such infrequent but potentially serious cases in the ENT emergency setting.

Structural Rules in Natural Deduction with Alternatives

Natural deduction with alternatives extends Gentzen–Prawitz-style natural deduction with a single structural addition: negatively signed assumptions, called alternatives. It is a mildly bilateralist, single-conclusion natural deduction proof system in which the connective rules are unmodi_ed from the usual Prawitz introduction and elimination rules — the extension is purely structural. This framework is general: it can be used for (1) classical logic, (2) relevant logic without distribution, (3) affine logic, and (4) linear logic, keeping the connective rules fixed, and varying purely structural rules. The key result of this paper is that the two principles that introduce kinds of irrelevance to natural deduction proofs: (a) the rule of explosion (from a contradiction, anything follows); and (b) the structural rule of vacuous discharge; are shown to be two sides of a single coin, in the same way that they correspond to the structural rule of weakening in the sequent calculus. The paper also includes a discussion of assumption classes, and how they can play a role in treating additive connectives in substructural natural deduction.

Bimodal-Bilingual Teacher Training in Sweden

Abstract: In 1981, Sweden was the first country in the world to entitle deaf pupils to a bimodal-bilingual education. However, drawing from interviews with key past Stockholm teacher trainers and on our own efforts to update teacher training, we note that sign-bilingual teacher training in Sweden has been ad hoc to this day. The interviewees' accounts highlight that deaf education is essentially about language access, that sign-bilingualism is core to the educational inclusion of all deaf pupils, and that only audism stands in the way of this. We argue against the Swedish national policy presumption of special need, pointing out that deaf pupils have an inalienable entitlement to sign language in much the same way that the right to speak Swedish is an inalienable part of being Swedish and not a need that only some Swedish people have. This makes national recognition of sign language a necessary precondition to deaf pupils' full educational inclusion. Policy should then likewise guarantee the sign-bilingual competence of teachers seeking to work with deaf pupils, this being a matter that necessarily conjoins educational and language (minority) rights as the two flipsides of one single coin.

From a one-mode to a multi-mode understanding of conical intersection mediated ultrafast organic photochemical reactions.

Over the last few decades, conical intersections (CoIns) have grown from theoretical curiosities into common mechanistic features of photochemical reactions, whose function is to funnel electronically excited molecules back to their ground state in regions where the potential energy surfaces (PESs) of two electronic states become degenerate. Analogous to transition states in thermal chemistry, CoIns appear as transient structures providing a kinetic bottleneck along a reaction coordinate. However, such a bottleneck is not associated with the probability of crossing an energy barrier but rather with an excited state decay probability along a full "line" of transient structures connected by non-reactive modes, the intersection space (IS). This article will review our understanding of the factors controlling CoIn mediated ultrafast photochemical reactions, taking a physical organic chemist approach by discussing a number of case studies for small organic molecules and photoactive proteins. Such discussion will be carried out by first introducing the "standard" one-mode model based on Landau-Zener (LZ) theory to describe a reactive excited state decay event intercepting, locally, a single CoIn along a single direction, and then by providing a modern perspective based on the effects of the phase matching of multiple modes on the same local event, thus redefining and expanding the description of the excited state reaction coordinate. The direct proportionality between the slope (or velocity) along one mode and decay probability at a single CoIn is a widely applied fundamental principle that follows from the LZ model, yet it fails to provide a complete understanding of photochemical reactions whose local reaction coordinate changes along the IS. We show that in these situations, in particular by focussing on rhodopsin double bond photoisomerization, it is mandatory to consider additional molecular modes and their phase relationship approaching the IS, hence providing a key mechanistic principle of ultrafast photochemistry based on the phase matching of those modes. We anticipate that this qualitative mechanistic principle should be considered in the rational design of any ultrafast excited state process, impacting various fields of research ranging from photobiology to light-driven molecular devices.

Late Iron Age coins of the Đurđevac (Gjurgjevac) tradition from Kuzelin (southwestern Pannonia)

The Late Iron Age hillfort site of Kuzelin on Medvednica in south-western Pannonia has yielded a not negligible number of coins, most of which can be classified among the types that are traditionally labelled “Tauriscan”. A single coin can be categorized as an East Celtic type from Transdanubia, while two further coins were struck by pairs of dies that also occur in the Samobor–Okić hoard and were thus produced simultaneously with the bulk of the hoard, whereas the remainder can be classified as recently recognized group of coins produced in the Đurđevac (Gjurgjevac) tradition. The latter represent the debased and reduced in weight and size coins inspired by the tetradrachms deposited as the Đurđevac hoard. They were issued at various sites in south-western Pannonia, testifying to different phases of striking and local developments in their production. Two subtypes of such coins were recognized in the numismatic record of Kuzelin and are here separated out as Kuzelin A and B types. The date of these coins corresponds to the archaeological material excavated at the site, i.e., to the Lt D1 period, ca. 150/130−70/50 BC.

Nález benátského grossa dóžete Pietra Gradeniga ze Svitav

A Single Coin Find of Venetian Grosso of Doge Pietro Gradenigo from Svitavy A medieval silver coin was found in the cadastral territory of Svitavy-předměstí (Svitavy District) by metal detecting in 2017. It was a Venetian grosso of Doge Pietro Gradenigo (1289–1311).

Effect of Teriparatide and Bisphosphonates in Advanced Patients with Osteoporosis

This paper mainly analyzes and studies the clinical treatment effect of teriparatide and bisphosphonates in elderly patients with osteoporosis.60 elderly osteoporosis patients admitted to our hospital from October 2021 to October 2022 were randomly selected and divided into two groups: observation group and control group by single and single coin method, and the number of patients in each group was 30.30 patients in the control group were treated with zoledronic acid for advanced osteoporosis, and 30 patients in the observation group were treated with teriparatide and bisphosphonate. Comparing the pain scores, bone density values, bone metabolism indicators and the incidence of adverse reactions between the two groups. Among them, the VAS score (1.22 ± 0.17) was lower than that of the control group (3.69 ± 1.30), (p <0.05); the observation group and the control group (p <0.05); the levels of calcium, blood phosphorus, osteocalcin and alkaline phosphatase increased after treatment, and the observation group, (p <0.05); there was no difference in adverse reactions between the observation group and the control group, (p> 0.05). The results show that for patients with osteoporosis, using teriparatide and bisphosphate sequential treatment, can effectively relieve the pain symptoms, and improve the bone mineral density, improve the bone metabolism index of patients, reduce the incidence of adverse reactions, ensure the safety and effectiveness of medication, can promote the application value in clinical high of a treatment.

Husby in Glanshammar: cloisonné production, Viking Period silver deposition and memorialisation

Abstract This paper returns to Husby in Glanshammar, Sweden, where an important manorial settlement of the mid-to-late 1st millennium AD was excavated in the 1990s for a highway project. A recent intensive and comprehensive metal detector survey of the site’s surviving parts has secured additional finds that cast a new light on the manor and its afterlife. Fine copper alloy casting was amply demonstrated by the 1990s excavations. Now a die for the making of waffled gold foil has been added to this assemblage. Waffled foils formed part of gold-and-garnet cloisonné work, one of the most exclusive decorative techniques of the era. Hacksilver and coins from around AD 900 were found scattered over the old foundation of the torn-down mead-hall, apparently forming a first phase of memorialisation that continued from about AD 1100 onward with a small Christian cemetery next to the foundation. These single coins go back at least half a century before the start of silver hoarding in the region. The silver found at Husby shows clear signs of having been used as bullion in economic transactions, with a high degree of fragmentation and many test marks.

Design, Fabrication, and Testing of Supercapacitor Based on Nanocarbon Composite Material

This research investigates the design, fabrication, and testing of single-cell and module supercapacitors. The supercapacitor consists of carbon nanocomposites, which contain activated carbon (AC), multiwall carbon nanotubes (MWCNT), and graphene (GR). The coin and pouch cell type supercapacitors were manufactured with AC: MWCNT: GR composite electrodes in a ratio of 70:20:10 weight percent. Meanwhile, the electrochemical characterization showed that the highest capacitance values for single coin and pouch cells were 32.13 F g-1 and 5.3 F g-1, respectively, in 6 M KOH electrolyte at a scan rate of 2 mV s-1. Furthermore, the power and energy densities for the coin-cell supercapacitor were 69 W kg-1 and 6.6 Wh kg-1, respectively, while for the pouch cell, it was 7.4 W kg-1 and 1.0 Wh kg-1, respectively. The coin-cell supercapacitor durability test was carried out for 1000 cycles, yielding the retention capacitance and coulombic efficiency values of 94-97% and 100%, respectively. These results showed that the performance of the supercapacitor is close to commercial products.

Isolation, marginalisation and disempowerment – understanding how interactions with health providers can influence smoking cessation in pregnancy

BackgroundMaternal smoking during pregnancy can lead to serious adverse health outcomes for both women and their infants. While smoking in pregnancy has declined over time, it remains consistently higher in women with lower socioeconomic circumstances. Furthermore, fewer women in this group will successfully quit during pregnancy.AimThis study explores the barriers to smoking cessation experienced by socially disadvantaged pregnant women and investigates how interactions with health providers can influence their smoking cessation journey.MethodsWomen (either pregnant or birthed in the previous 10 years, who smoked or quit smoking in pregnancy) were recruited from a metropolitan public hospital antenatal clinic in South Australia and community organisations in surrounding suburbs. Seventeen women participated in qualitative semi-structured small focus groups or interviews. The focus groups and interviews were recorded, transcribed and thematically analysed.FindingsFour interconnected themes were identified: 1) smoking embedded in women’s challenging lives and pregnancies, 2) cyclic isolation and marginalisation, 3) feeling disempowered, and 4) autonomy and self-determination. Themes 3 and 4 are characterised as being two sides of a single coin in that they coexist simultaneously and are inseparable. A key finding is a strong unanimous desire for smoking cessation in pregnancy but women felt they did not have the necessary support from health providers or confidence and self-efficacy to be successful.ConclusionWomen would like improvements to antenatal care that increase health practitioners’ understanding of the social and contextual healthcare barriers faced by women who smoke in pregnancy. They seek improved interventions from health providers to make informed choices about smoking cessation and would like women-centred care. Women feel that with greater support, more options for cessation strategies and consistency and encouragement from health providers they could be more successful at antenatal smoking cessation. If such changes were made, then South Australian practice could align more with best practice international guidelines for addressing smoking cessation in pregnancy, and potentially improve outcomes for women and their children.

A Preliminary Report on a Search for Artefacts and Verification Excavations Conducted within the Limits of the Old Village of Trójca in 2020 and 2021

In 2020–2021, within the limits of Trójca – a medieval village located near a ford on the Vistula River that is today part of Zawichost – artefacts were sought with the use of metal detectors. Next, a survey excavation was conducted, resulting in the discovery of e.g. two silver hoards from the 11th and 12th c., single coins from the 11th–12th c. (over 140 specimens) and from later times, merchant’s weights, adornments, minor devotional articles and military accessories (especially from the 11th–13th c.) and many other artefacts. Their discovery makes us suspect that Trójca was one of the most important supralocal trade centres of Lesser Poland in the early Middle Ages. The conducted excavations and research are only the first stage for future archaeological prospections to be conducted in Trójca and will be continued in the years to come.

Praha-Vinoř. Opevněné centrum prvních Přemyslovců ve světle mincovních nálezů

The study presents single coin finds obtained by the systematic metal detector survey from the area of the settlement complex in Prague-Vinoř. Here, a stronghold of the first Přemyslids with an associated settlement were established at the turn of the 9th and 10th centuries. In the 11th and 12th centuries, a large (probably church) burial ground and a high medieval manorial seat existed in this area. To date, a total of 58 single coin finds have been recorded from all the above-mentioned locations, with 16 coins dating from the 10th to early 13th centuries. The oldest is a unique coin of the bishop of Augsburg, St. Ulrich of Augsburg, minted in the early days of his coinage (perhaps even before the conventional year 955), the rest are domestic deniers. 17 coins belong to the years 1300–1526, 9 coins were struck before the last quarter of the 16th century. The remaining 13 individual coins were minted after the year 1648. The single coin finds present irreplaceable but rapidly disappearing evidence of the changing socio-economic functions of the site, and the development of the cultural landscape.

Mince z archeologických výzkumů v areálu kláštera Sázava

During 1940–1992, systematic archaeological researches were carried out in the area of the Sázava Monastery resulting – among other things – with total of 164 single coin finds. The assemblage of this numismatic material represents a unique insight into the currency circulation from the 11th century to the early modern period. The beginning of the Hussite Era, associated with the expulsion of the monks from the Monastery, meant a fundamental change that has been reflected also in the considerable decrease of coin finds in the examined area (Tab. no. 1). Lost coins and coins found in grave contexts prevail in the collected numismatic evidence. A chronologically structured study of the coin finds is also part of this article. The analysis of the coins of the Luxembourg rulers, including important contribution to the classification of some small denomination types, is of a particular interest here. Special attention is also paid to the coins found in grave contexts – the published material presents the largest assemblage of such sources dated to the period from the 13th to 15th centuries, found in the territory of the Czech Republic (Tab. 2).

Silver coins, wooden tallies and parchment rolls in Henry III's Exchequer

In the mid thirteenth century, England used only a single coin, the silver penny. The flow of coins into and out of the government's treasury was recorded in the rolls of the Exchequer of Receipt. These receipt and issue rolls have been largely ignored, compared to the pipe rolls, which were records of audit. Some more obscure records, the memoranda of issue, help to show how the daily operations of government finance worked, when cash was the only medium available. They indicate something surprising: the receipt and issue rolls do not necessarily record transactions which took place during the periods they nominally cover. They also show that the Exchequer was experimenting with other forms of payment, using tally sticks, several decades earlier than was previously known. The rolls and the tallies indicate that the objectives of the Exchequer were not, as we would now expect, concerned with balancing income and expenditure, drawing up a budget, or even recording cash flows within a particular year. These concepts were as yet unknown. Instead, the Exchequer's aim was to ensure the accountability of officials, its own and those in other branches of government, by allocating financial responsibility to individuals rather than institutions.

Esophageal discoid foreign body detection and classification using artificial intelligence.

Early and accurate radiographic diagnosis is required for the management of children with radio-opaque esophageal foreign bodies. Button batteries are some of the most dangerous esophageal foreign bodies and coins are among the most common. We hypothesized that artificial intelligence could be used to triage radiographs with esophageal button batteries and coins. Our primary objective was to train an object detector to detect esophageal foreign bodies, whether button battery or coin. Our secondary objective was to train an image classifier to classify the detected foreign body as either a button battery or a coin. We trained an object detector to detect button batteries and coins. The training data set for the object detector was 57 radiographs, consisting of 3 groups of 19 images each with either an esophageal button battery, esophageal coin or no foreign body. The foreign bodies were endoscopically confirmed, and the groups were age and gender matched. We then trained an image classifier to classify the detected foreign body as either a button battery or a coin. The training data set for the image classifier consisted of 19 radiographs of button batteries and 19 of coins, cropped from the object detector training data set. The object detector and image classifier were then tested on 103 radiographs with an esophageal foreign body, and 103 radiographs without a foreign body. The object detector was 100% sensitive and specific for detecting an esophageal foreign body. The image classifier accurately classified all 6/6 (100%) button batteries in the testing data set and 93/95 (97.9%) of the coins. The remaining two coins were incorrectly classified as button batteries. In addition to these images with a single button battery or coin, there were two unique cases in the testing data set: a stacked button battery and coin, and two stacked coins, both of which were classified as coins. Artificial intelligence models show promise in detecting and classifying esophageal discoid foreign bodies and could potentially be used to triage radiographs for radiologist interpretation.

Symbols on ancient Indian coins uncyphered

Ancient Indian coins from Pre-Mauryan era has been filled with a certain mystery as well as speculation. The coins in reference are punch marked coins. What is stamped in these coins have long since been considered symbols without really a clear meaning. The only ones which can be clearly understood are the ones which are images of animals such as elephants. What has been in front of our eyes all this time, remained obscured, due to erroneous human thinking. What I have found is characters in Brahmi Script and will show and provide the Sanskrit interpretations on not just a single coin but multiple coins in different periods in Ancient Indian history.
