Introducere. Otita medie (OM) acută este una dintre cele mai comune infecţii diagnosticate în patologia copilului, cu evoluţie autolimitată cel mai frecvent (1,2). Ea poate duce în 2-6% dintre cazuri (2) spre complicaţii supurative intracraniene cu evoluţie nefavorabilă, fatală în 8-26,3% din ele (2,3). Apariţia semnelor neurologice în evoluţia unei otite supurative necesită investigaţii imagistice de urgenţă (2-8). Material şi metodă. Se prezintă cazul unei fetiţe de 10 ani diagnosticată cu otită supurată complicată, transferată la Spitalul Clinic de Urgenţă pentru Copii „M.S. Curie“ Bucureşti în secţia ORL după o evoluţie a bolii de 2 săptămâni. Copilul se prezintă la internare cu: febră, otoree purulentă, semne neurologice reprezentate de cefalee, convulsii, redoare de ceafă. Se efectuează în urgenţă un examen computer tomografic (CT) cu substanţă de contrast intravenoasă (iv). Rezultat. Examenul CT, extins şi la nivel cervical evidenţiază prezenţa unui proces litic la nivelul stâncii temporale şi soluţie de continuitate între antrul mastoidian şi meninge, şi evidenţierea unui abces epidural perisigmoidian, tromboza de sinus sigmoid extinsă la nivelul jugularei şi sinusului lateral, semne de meningită, cerebrită cerebeloasă, abces cerebral şi empiem subdural. Concluzii. Complicaţiile în infecţiile urechii medii sunt rare, însă apariţia semnelor neurologice la examenul fizic impune un examen imagistic care poate preciza arhitectura locală, prezenţa complicaţiilor locale sau la distanţa pentru instituirea unui tratament adecvat şi rapid.

Vă prezentăm un caz atipic de diabet zaharat de tip I la debut, cu multiple abcese, diagnostic confirmat de testele de laborator. Acest caz este al unei fete în vârstă de 14 ani care s-a prezentat cu abcese ale coapselor şi ale zonei inghinale. Analizele obişnuite efectuate au arătat hiperglicemie cu glucoză în urină, însoţite de scădere ponderală, poliurie şi polidipsie. Abcesele au fost incizate şi drenate. Semnele patologice întâlnite la examenul obiectiv au fost: stare generală influenţată, turgor cutanat diminuat, buze uscate, multiple abcese fi stulizate ale coapselor, hipogastrice şi ale zonei inghinale, faringe şi amigdale hiperemice. Analizele de sânge au descoperit hiperglicemie (272 mg/dl), leucocitoză cu granulocitoză, trombocitoză, valori crescute ale hemoglobinei. Datele clinice şi para clinice au fost sugestive pentru diabet zaharat de tip I complicat cu abcese. Tratamentul a constat în terapie de substituţie cu insulină asociată cu antibiotice, antimicotice, analgezice, antipiretice, perfuzii pentru rehidratare. Evoluţia cazului a fost favorabilă sub tratament cu insulină, starea abceselor cutanate s-a îmbunătăţit foarte mult după tratamentul chirurgical şi cel antibiotic, dar s-au vindecat complet doar după echilibrarea diabetului zaharat. În concluzie, deşi în literatura de specialitate este raportată apariţia infecţiilor cutanate multiple la pacienţii cu diabet zaharat incorect trataţi, acestea sunt rar diagnosticate la debutul acestei boli la copii, acest fapt fiind datorat cel mai probabil debutului adesea acut la această vârstă.

Introduction. Community-acquired pneumonia is one of the leading causes of death worldwide in children under 5 years. In practice, viral detection using multiplex PCR is becoming increasingly used, it is most useful to understand the epidemiology and impact of viruses on the pediatric population but there are still many debates regarding the influence of viral detection on patient care. Objectives. In this study we aimed to analyze the impact of viral etiology determination on the duration of hospitalization and on the administered treatment. Material and methods. The selection criteria was: children between 0-5 years with severe lower respiratory tract infection. We have analyzed three groups of patients: a group with specified viral infection, a second group with unspecified viral infection and a third group with bacterial infection. Results. In the analyzed period 72 children under 5 years of age who have shown signs of acute respiratory failure have been diagnosed with a specific viral infection, only 2% of the total viral infections. The main etiology was represented by respiratory syncytial virus (RSV) in 73.5% of cases, followed by Influenza 11%, Parainfluenza 4.2%, metapneumovirus (hMPV), Rhinovirus, Adenovirus and Bocavirus all with 2.8%. Within the unspecified viral infection group antibiotics were used in 85.5% (n = 53) of the cases. Within the specified viral infection group although viral etiology was firmly established antibiotics usage rate was higher 92% (n = 57). Duration of hospital stay was 2,5 days higher in the viral specified group compared with the unspecified one. Thus we found that although the diagnosis of viral infection was certainly given because of severe clinical picture and young age of children the expenses were 30% higher. Conclusions. In our study, RSV is the most common virus involved in the etiology of viral LRTI and is encountered in the most severe forms of the disease especially in young infants and prematures. Antibiotics are commonly used in the severe forms of LRTI, even if the viral etiology is certain and the groups of antibiotics used are similar. Determination of viral etiology has not reduced hospitalization, nor has led to changing of physician therapeutic approach.

Kooperative Raumplanung: Handlungsformen und Verfahren
Authors: Hoffmann Kristin
Published: July 2021

Cooperative planning is a potent approach for steering quality settlement development inwards. With the combination of (special) use plans and urban development contracts, they come into play where traditional spatial planning is unable to reliably achieve the desired spatial planning due to a lack of agreements with landowners or investors. While private individuals benefit from a better use of their land, the state gains influence on the "if" and "how" of the constructional realization of this land. The considerable urban planning significance of cooperative planning is contrasted by constitutional concerns about the method. Cooperative planning runs the risk of shortchanging legitimate public and third-party interests and of overreaching to the private cooperating party because of the state's bidding power in the area of land use planning. This book shows ways how cooperative planning can be designed according to rule-of-law standards and thus be strengthened.

New records of alien and potentially invasive grass (Poaceae) species for southern Africa
Authors: Sylvester Steven P. , Soreng Robert J. , Sylvester Mitsy D.P.V. , Mapaura Anthony , Ralph Clark Vincent
Published: July 2021

Background: The grasses (Poaceae) of the Flora of Southern Africa (FSA) region (i.e. Botswana, Eswatini, Lesotho, Namibia and South Africa) are relatively well documented, for both native and non-native species. Visiting taxonomic expertise nevertheless reveals new FSA and in-country records, particularly of non-native species. Such records provide an opportunity for improving biosecurity relating to potentially invasive but hitherto undetected non-native Poaceae in the FSA region.Objectives: To improve floristic data for non-native Poaceae occurring in theFSA region.Method: Field collections were made, herbarium collections, databases and relevant literature were studied.Results: New records are presented for non-native grasses that were encountered as locally common populations in the Drakensberg Mountain Centre of Floristic Endemism (DMC, Lesotho and South Africa). Festuca rubra and Agrostis capillaris are newly reported for sub-Saharan Africa and southern Africa and are also the first verified specimens reported for the African continent, with previous reports from northern-most Africa (Morocco, Algeria and/or Tunisia) uncertain. Jarava plumosa, introduced from South America and previously known for the whole of Africa from a single population in the Western Cape, South Africa, is newly reported from the border between the Eastern Cape, South Africa and Lesotho. The ecological implications, including the potential to become invasive, are discussed for each species, with taxonomic notes given to help differentiate them from closely resembling taxa.Conclusion: These new records of alien grass species raise concerns over their potential ecological impact, particularly as they are found in an area of conservation importance. Future efforts to monitor their distribution are of importance.
Una vuelta de tuerca a la filantropía: lógica de la muerte y ‘ética del otro’ en Salón de belleza de Mario Bellatin
Authors: VILLAMÍA LUIS
Published: July 2021

El hermetismo de universos cerrados y la opacidad de la peculiar escritura experimental de Mario Bellatin han suscitado diversas interpretaciones de su obra más celebrada y leída, Salón de belleza (1994), vinculadas sobre todo con la dimensión corporal y la enfermedad. Sin embargo, creo que hay también una vertiente en la novela especialmente valiosa y enigmática: su interpretación desde una perspectiva ética. ¿Cómo puede ser que la historia de un hombre entregado de esa forma incondicional al cuidado de los más vulnerables suscite sin embargo una lectura sombría y despiadada? Probablemente la respuesta tenga que ver con lo que el propio Bellatin denomina ‘lógica de la muerte’. Para adentrarnos en el estudio de la obra desde esta óptica examinamos en primer lugar la noción de eutanasia pasiva que practica el protagonista en el Moridero en contraste con nuestra percepción actual de muerte ideal inspirada en la necesidad de medicalizar el sentimiento de la muerte y alargar la vida a través de la tecnología. Asimismo, en la segunda parte del artículo, analizamos el enorme sacrificio del protagonista hacia los más desfavorecidos desde la categoría de la ‘ética de los otros’, inspirada en las reflexiones de Emmanuel Lévinas.
Challenges and Distortions of Translating Grammatical Gender in Literary Texts: Julio Cortázar Translated into Various European Languages
Authors: NISSEN UWE KJÆR
Published: July 2021

With a focus on various translations of the short story ‘Historia con migalas’ by one of the most renowned Latin American writers, the Argentinian author Julio Cortázar, this article describes and exemplifies numerous translational problems with respect to grammatical gender. In spite of the difficulties in Spanish of entirely avoiding gender/ sex references, Cortázar deliberately endeavours (successfully) to hide the gender of the protagonist couple by tricking the reader into a heterosexual, stereotypical mindset until, at the end of the story, he reveals that the couple consists of two women, forcing the reader to reanalyse and reinterpret the entire story. As this article shows, not all translators seem to be aware of Cortázar’s subtle play with grammatical gender, and vice versa - in this case - biological gender and, therefore, entirely miss the quintessence of the story. A relevant question that arises is whether it is possible in the languages under consideration to translate this playing with gender at all, or whether constraints as to the structure of the languages impede it (for example, differences between grammatical gender and natural gender languages). Finally, some evidence is brought forward to address the question of how the (mis)translated short stories were received by reviewers.

The Galactic microquasar GRS 1915+105 shows rich variability that is categorized into different classes. In this paper, we report the temporal and spectral analysis of GRS 1915+105 to study the properties of the accretion flow when the light curve shows θ class variability. For this purpose, we use the Large Area X-ray Proportional Counter data from the Target of Opportunity observations of India’s first multiwavelength astronomy satellite AstroSat. The θ class is marked by the recurrent appearance of U-shaped regions in the light curve, where the photon count rate first decreases rapidly and then increases slowly. For our analysis, we use U-shaped regions of the first two orbits (02345 and 02346) on 2016 March 4. In both cases, the dynamic power-density spectra (PDS) showed significant power at around 4–5 Hz, suggesting the presence of a low-frequency quasi-periodic oscillation (QPO) around that frequency interval. The QPO frequency is found to increase with time when the energy flux is also enhanced. From the evolution of the spectra, we determine the evolution of the accretion flow parameters in these two observations. Fitting the spectra with the transonic flow solution-based two-component advective flow (TCAF) model in the 4–25 keV energy band shows that the Keplerian disk accretion rate increases with the increase in radiation intensity, while the location of the centrifugal pressure-driven shock front decreases. In both these data, a gradual increment of power-law photon index with intensity is observed, suggesting the progressive softening of the source.
Brightness Fluctuation Spectra of Sun-like Stars. I. The Mid-frequency Continuum

Published: July 2021

We analyze space-based time-series photometry of Sun-like stars, mostly in the Pleiades, but also field stars and the Sun itself. We focus on timescales between roughly 1 hr and 1 day. In the corresponding frequency band these stars display brightness fluctuations with a decreasing power-law continuous spectrum. K2 and Kepler observations show that the rms flicker due to this mid-frequency continuum (MFC) can reach almost 1%, approaching the modulation amplitude from active regions. The MFC amplitude varies by a factor up to 40 among Pleiades members with similar T
eff, depending mainly on the stellar Rossby number Ro. For Ro ≤ 0.04, the mean amplitude is roughly constant at about 0.4%; at larger Ro the amplitude decreases rapidly, shrinking by about two orders of magnitude for Ro ≃ 1. Among stars, the MFC amplitude correlates poorly with that of modulation from rotating active regions. Among field stars observed for 3 yr by Kepler, the quarterly average modulation amplitudes from active regions are much more time variable than the quarterly MFC amplitudes. We argue that the process causing the MFC is largely magnetic in nature and that its power-law spectrum comes from magnetic processes distinct from the star’s global dynamo, with shorter timescales. By analogy with solar phenomena, we hypothesize that the MFC arises from a (sometimes energetic) variant of the solar magnetic network, perhaps combined with rotation-related changes in the morphology of supergranules.

Published: July 2021

The radio radiation mechanism is one of the open questions for pulsars. Multiband observations are very helpful to constrain pulsar radiation models. We observed PSR J1848-0123 at the 5 GHz band with the Shanghai Tianma 65 m radio telescope (TMRT). The 5 GHz observation together with the European Pulsar Network (EPN) and CSIRO ATNF Data Archives databases provides a broadband evolution property of the pulse profiles for this pulsar. We reprocessed these data sets to obtain the multiband pulse profiles. It was found that the pulse profile of PSR J1848-0123 narrows with increasing emission frequency. We separated the emission components of each pulse profile with a multi-Gaussian fitting method, and then calculated the beaming angle and emission radius of each component with the basic radiation geometry of pulsar. With the calculated beam angles and radiation radii, we simulated the radius-frequency mapping of this pulsar with an inverse Compton scatting model (ICS). It was found that the observed radio radiation could be generated in the core gap region above the polar cap of the pulsar. The beaming angle and emission radius versus frequency for PSR J1848-0123 can be explained well with the ICS model.
The power of metabarcoding: Can we improve bioassessment and biodiversity surveys of stream macroinvertebrate communities?
Authors: Turunen Jarno , Mykrä Heikki , Elbrecht Vasco , Steinke Dirk , Braukmann Thomas , Aroviita Jukka
Published: July 2021

Most stream bioassessment and biodiversity surveys are currently based on morphological identification of communities. However, DNA metabarcoding is emerging as a fast and cost-effective alternative for species identification. We compared both methods in a survey of benthic macroinvertebrate communities across 36 stream sites in northern Finland. We identified 291 taxa of which 62% were identified only by DNA metabarcoding. DNA metabarcoding produced extensive species level inventories for groups (Oligochaeta, Chironomidae, Simuliidae, Limoniidae and Limnephilidae), for which morphological identification was not feasible due to the high level of expertise needed. Metabarcoding also provided more insightful taxonomic information on the occurrence of three red-listed vulnerable or data deficient species, the discovery of two likely cryptic and potentially new species to Finland and species information of insect genera at an early larval stage that could not be separated morphologically. However, it systematically failed to reliably detect the occurrence of gastropods that were easily identified morphologically. The impact of mining on community structure could only be shown using DNA metabarcoding data which suggests that the finer taxonomic detail can improve detection of subtle impacts. Both methods generally exhibited similar strength of community-environment relationships, but DNA metabarcoding showed better performance with presence/absence data than with relative DNA sequence abundances. Our results suggest that DNA metabarcoding holds a promise for future anthropogenic impact assessments, although, in our case, the performance did not improve much from the morphological species identification. The key advantage of DNA metabarcoding lies in efficient biodiversity surveys, taxonomical studies and applications in conservation biology.
The impact of large dams on fluvial sedimentation: The Iron Gates Reservoir on the Danube River

Published: July 2021

Dam construction is one of the major human pressures impacting fluvial processes, including topography and hydro-sedimentary flows, as a result of the change in flow regime from fluvial to fluvial-lacustrine. This article investigates geomorphic changes at Iron Gates I, the largest reservoir on the Danube River, completed in 1972 for hydropower and navigation. The study focuses on a gulf area that emerged at the mouth of the Cerna River into the reservoir, highlighting spatial changes in topography and sediment distribution, based on a diachronic analysis of two datasets before and after the dam was built: one extracted from historical topographic maps and the other obtained from a bathymetric echo sounding survey, integrated within a GIS analysis. The results reveal the dominance of the sedimentation process, with an alluvium layer thickness up to 14 m. The current sediment pattern has changed the submerged morphology, leading to the formation of an alluvial fan at the mouth of the Cerna River and of a sedimentary bar between the Cerna Gulf and the Danube River’s channel. The siltation process together with the current underwater morphology limits ship traffic and the storage capacity of the reservoir.

Attitudes Towards using Digital Technologies in Education as an Important Factor in Developing Digital Competence: The Case of Slovenian Student Teachers
Authors: Štemberger Tina , Čotar Konrad Sonja
Published: July 2021

The purpose of the study was to determine what attitudes specifically Slove-nian student teachers hold towards using digital technologies in education, their self-reported proficiency in using digital technologies in education and to what extent their attitudes towards using digital technologies in education predict their self-reported proficiency in using digital technologies. We measured the attitudes towards using digital technologies in education through four dimensions: Teaching and learning, Assessment and critical thinking, Empowering learners and Facilitating learner’s digital competence. Self-reported proficiency in using digital technology was measured on four groups of digital technologies: Digital resources, Communication tools, Digi-tal tools and Online learning tools. The results show that Slovenian student teachers predominantly hold positive attitudes towards using digital technol-ogies in education, but they assess themselves as low-level users. Also, the student teachers’ attitudes towards using digital technologies in education were proved as an important predictor of their level of proficiency in using digital technologies.

Published: July 2021

The national digital identity platform is a robust scheme that enables individuals and entities to prove who they are to digitally access critical information or services. However, current digital identity systems do not sufficiently consider delegation between entities from the viewpoint of dynamic authorizers and permissions. This study aims to understand the pain points and expectations of end-users and service providers in the Thai national digital identity platform, to design a dynamic delegation model and develop an innovative delegation application to test user acceptance. The research utilizes semi-structured interviews with 3 digital identity experts, two focus groups, one with 6 service providers, and the other one with 6 end-users. Based on results from the data analysis and conceptual prototype design, validated by experts, the proposed prototype is practical and suitable for developing a digital delegation mobile web application that is convenient, safe, secure, and reliable utilizing blockchain technology under the Thai national digital identity platform. The technology acceptance model was used to test the application acceptance with 42 participants. The result reveals that both person and businesses intend to adopt the digital delegation mobile web application. Use cases of the application include users give their power to trusted entities and Government Agency to provide services to the citizens via the authorized delegatee.

A 70-year-old male presented with orbital masses affecting the muscular cone. His past medical history was notable for diabetes mellitus, ischemic cardiopathy, sleep-apnea syndrome, and multiple serous effusions. The first biopsy specimen of affected orbital tissue revealed fibrohistiocytic infiltration resembling xanthogranuloma or Erdheim–Chester disease (ECD). An ulterior biopsy of affected orbital tissue showed lymphocyte emperipolesis with immunopositivity for CD68 and S100 but negative staining for CD1a marker, strongly suggesting Rosai–Dorfman disease (RDD). Afterward, pericardium and peritoneal effusions resulted in constrictive pericarditis and retroperitoneal fibrosis, respectively. The absence of distinctive clinical features made the diagnosis especially challenging. Attempts to control the disease using corticosteroids, radiation, orbital surgery, and interferon were unsuccessful. Aggressive treatments such as chemotherapy were not considered appropriate due to the general deterioration of our patient. Although the possibility of two concurrent diseases (e.g., systemic ECD and orbital RDD) cannot be discarded, we interpreted the orbital findings as likely due to RDD, and the entire condition of our patient as an extranodal RDD with atypical clinicopathological findings and outcome.

Published: July 2021

Context/Aims: Given the limitations of current navigation-guided brain biopsy methods, we aimed to introduce a novel method and validate its safety and accuracy. Setting and Design: This was a retrospective study of twenty consecutive patients who underwent brain biopsy at Shimane University Hospital, Japan. Subjects and Methods: Clinical records of 13 and 7 patients who underwent brain biopsy with the novel frameless free-hand navigation-guided biopsy (FFNB) method or a framed computed tomography-guided stereotactic biopsy (CTGB) method, respectively, were retrospectively reviewed. We compared age, sex, tumor location, histological diagnosis, maximum size of the tumor (target), depth from target to cortical surface on the same slice of CT or magnetic resonance imaging, operative position, anesthesia method, setup time for biopsy, incision-to-closure time, trial times for puncture, success rate, and complications in the two groups. Statistical Analysis: Fisher's exact test and the Wilcoxon rank-sum test were performed. Results: Clinical characteristics and lesion size did not differ significantly between the FFNB and CTGB groups. The depth of the target lesion was significantly greater in the CTGB group (P < 0.05). All FFNB and CTGB procedures reached and obtained the target tissue. The number of punctures and the average incision-to-closure time did not differ between the FFNB and CTGB groups. However, the preoperative setup time was significantly shorter using FFNB (P = 0.0003). No complications were observed in either group. Conclusions: FFNB was comparable with CTGB in terms of safety, accuracy, and operative duration. The preoperative setup time was shorter using FFNB. Therefore, FFNB is a feasible method for brain tumor biopsy.

The development and fabrication of integrated circuits for the applicational areas of VLSI such as processing of the signal, medicine tomography, telecommunication turn out to be a novel technology for the upcoming innovations. The fabrication of IC’s is attributable to the methodology in the technology of VLSI and when compared to artificial Neural Network, the genetic performance of these productions is approximately the same and are typically employed for diagnosing the syndrome, compression as well as the decompression of signal used in the medical domain. Techniques such as HMM, DCT, as well as PCA are employed for compression and decompression of signals but these approaches still possess some disadvantages. Therefore, to overcome these issues, a chip-level design for Artificial Neural Network is proposed that makes use of FinFET 32 nm technology and includes sigmoid activation function (SAF), Gilbert cell number, as well as bias circuits to prolong the compressed magnitude relation and accuracy. As a result, with the help of the Cadence Virtuoso analog tool, the Artificial Neural Network has been designed using FinFET 32nm technology along with all the details of sub-units such as Layout vs Schematic (LVS), Design rule check (DRC), RC extraction as well as chip level (GDS-II). Feed Forward Artificial Neural Network (FWANN) is considered as one of the most basic types of ANN and it is implemented using the concept of Back Propagation (BP). The simulation results of the suggested 16-bit 6TRAM cell were found to have 8%, 21%, and 0.9% improvement in consuming power, delay, and compressed data losses respectively.

Farming is an activity carried out by humans to utilize biological resources, especially for producing food. Bale Village, Oba District, Tidore, Halmahera Island, North Maluku is inhabited by the Makian ethnic group, originating from Makian Island. They are local transmigrants. In this study, researchers conducted direct observation and interviews with key informants who had expertise and information in agriculture at the research location. The results showed that the farming is carried out in yards (kintal) and fields (doba). The agricultural pattern implemented by the Makian people is still traditional. They still use simple technology. Coconut, nutmeg, cocoa, and coffee are the Makian people’s main commodities. The local wisdom that is still practiced by them is planting and harvesting their agricultural products according to the customs of their ancestors. They also do not sell their agricultural land to outsiders.

Published: July 2021

This study analyzes the impact of education, health policy initiatives i.e. selection of treatment arms of ambulatory vs. hospital care and financial incentives under taken by the National Tuberculosis Program of Pakistan (NTP) on the outcome of cure of multi-drug resistance tuberculosis patients. The data of 370 patients enrolled in randomized control trial is collected from three TB centers of Lahore, Karachi and Murree and multi-variate logistic regression method is applied. The empirical findings show that formal education and selection of treatment arm do not significantly affect the outcome of the cure. However, health literacy provided by the NTP plays vital role in improving the treatment outcomes. Therefore, it is suggested that health literacy should be focused in our formal education for the improvement of the health-status of the nation. Moreover, WHO (2011) recommendation of shift towards ambulatory care is applicable for Pakistan and financial incentives should continue as it reduces the treatment burden for patients.

Published: July 2021

ABSTRACT

The present work describes the development of an open loop temperature control system in a container through a Peltier Cell. The control consists of applying a PWM signal to the thermoelectric device, which controls the temperature in a range of 5 to 90 °C. A study was carried out to characterize the frequency and duty cycle of the PWM and thus determine the best operating conditions for the thermoelectric element. In addition, a power stage was implemented to change the supply polarity in the Peltier cell and, in this way, to be able to exchange the heating and cooling faces. The study carried out leaves the basis for implementing climatization system on a larger scale using thermoelectric elements in a novel and versatile way.

Breach of contract
Authors: Clive E
Published: July 2021

This contribution uses J & H Ritchie Ltd v Lloyd Ltd 2007 SC (HL) 89 as a peg on which to hang a number of fundamental questions about contract: What is a contract? Does the word ‘contract’ sometimes refer to a legal relationship rather than a juridical act? If so, does this matter? Is the law on implied terms satisfactory? Might a duty of good faith and fair dealing in contract law be a better way of dealing with certain problems than resort to the implication of terms? When is a breach of contract serious enough to justify cancellation or rescission? Should a supplier of defective goods have a right to cure the defect? Is there a risk of forgetting the difference between a right to withhold performance and a right to rescind or cancel? These questions are prompted by the fact that this was a straightforward case and similar situations must occur regularly. Yet, different judges reasoned differently and came to different conclusions in the course of the case being appealed all the way to the House of Lords. The question, therefore, is: how might a simple case have been better, or in a more straightforward way, approached through law? The contribution argues that the Draft Common Frame of Reference (the DCFR) provides both concepts and rules that would have reached the ultimate conclusion in Ritchie much more quickly and perhaps the case would not have needed to be litigated at all.
