Abstract Maintaining prolonged service lifetime and adequate quality of sensing coverage are the key challenges in constructing Wireless Sensor Network (WSN) based applications. As such networks usually operate in inhospitable and hostile environment, failures are ineludible and providing resilience is a necessity. However, it is challenging to satisfy the conflicting problems of enhancing energy efficiency and fault tolerance simultaneously. Fault-tolerance is a significant requirement while designing WSN. It is crucial to detect the failures in advance and take necessary measures to maintain durable and efficient functioning of the network. Generally, in the existing face structured WSNs, node faults and failures can induce the formation of coverage holes, disrupt the face structure and consequently curtail the application performance. The coverage quality will affect the monitoring effectiveness of tracking applications, e.g., a moving target tracking. Moreover, node failures can cause the network to be partitioned, further reducing the accuracy in tracking. In this paper, we propose a robust fault-tolerance scheme with coverage preservation using a face structured WSN topology (FCAFT ). The key objective of the proposed FCAFT scheme is to sustain the performance of the network by timely healing the faults in the network, to enhance the durability and reliability of the WSN. The results of simulation and comparison with existing methods reveal that FCAFT is efficacious in sustaining the coverage and enhancing the service lifetime of WSN, which is a necessity for critical monitoring and tracking applications of WSNs.

Pain is a significant and alarming symptom of cancer seriously affecting the activity and quality of life of patients. Recent research proved that inadequate analgesia shortens life expectancy. Therefore, pain relief is not only a possibility but a professional, ethical and moral commitment to relieve patients from suffering, as well as ensure their adequate quality of life and human dignity. Proper pain relief can be achieved with medical therapy in most of the cases and the pharmacological alternatives are available in Hungary. Yet medical activity regarding pain relief is far from the desired. This paper gives a short summary of the guidelines on medical pain management focusing particularly on the use of opioids. Orv.

There are many steps in fabrication of dental crowns and bridges at which an error can occur, and a technician can only fabricate a quality restoration if the impression itself is of adequate quality. All dental practitioners should have the ability to evaluate the quality of dental impression before sending to the laboratory. Elastomeric silicones (polysiloxane) are the most utilised impression materials in dental practice. The present study deal with the deficiencies of silicones dental impressions sent to commercial dental laboratories for fabrication of single crowns and bridges.

One third of food produced globally is wasted. Disposal of this waste is costly and is an example of poor resource management in the face of elevated environmental concerns and increasing food demand. Providing this waste as feedstock for black soldier fly (Hermetia illucens) larvae (BSFL) has the potential for bio-conversion and valorisation by production of useful feed materials and fertilisers. We raised BSFL under optimal conditions (28 °C and 70% relative humidity) on seven UK pre-consumer food waste-stream materials: fish trimmings, sugar-beet pulp, bakery waste, fruit and vegetable waste, cheese waste, fish feed waste and brewer’s grains and yeast. The nutritional quality of the resulting BSFL meals and frass fertiliser were then analysed. In all cases, the volume of waste was reduced (37–79%) and meals containing high quality protein and lipid sources (44.1 ± 4.57% and 35.4 ± 4.12%, respectively) and frass with an NPK of 4.9-2.6-1.7 were produced. This shows the potential value of BSFL as a bio-convertor for the effective management of food waste.

Automated Line

In order to add value to recycled textile material and to guarantee that the input material for recycling processes is of adequate quality, it is essential to be able to accurately recognise and sort items according to their material content. Therefore, there is a need for an economically viable and effective way to recognise and sort textile materials. Automated recognition and sorting lines provide a method for ensuring better quality of the fractions being recycled and thus enhance the availability of such fractions for recycling. The aim of this study was to deepen the understanding of NIR spectroscopy technology in the recognition of textile materials by studying the effects of structural fabric properties on the recognition. The identified properties of fabrics that led non-matching recognition were coating and finishing that lead different recognition of the material depending on the side facing the NIR analyser. In addition, very thin fabrics allowed NIRS to penetrate through the fabric and resulted in the non-matching recognition. Additionally, ageing was found to cause such chemical changes, especially in the spectra of cotton, that hampered the recognition.

The use of videoconferencing in psychotherapy remains largely unexplored. Videoconferencing compromises the range and quality of interactional information and thus might be expected to affect the working alliance (WA) between client and therapist, and consequently the process and outcome of therapy. A single case study exploring the effect of videoconferencing on the development of the WA in the psychological treatment of a female–male transsexual is described. The self-rated Working Alliance Inventory (WAI) was used to measure client and therapist perceptions of the WA after each session over 10 sessions of eclectic therapy conducted over a videolink. The serial WAI measurements charting the development of the WA in 4 cases of 10-session, face-to-face therapy by Horvath and Marx1 were used as a quasi-control. Therapist and client impressions of teletherapy are described. WAI scores were essentially similar to the face-to-face control group except for lower client-rated bond subscale scores. It is suggested that client personality factors accounted for this difference and that videoconferencing did not impair the development of an adequate working alliance or successful therapeutic outcome.

Currently, the need to ensure adequate quality of air inside the living space but also the thermal efficiency of buildings is pressing. This paper presents the capacity of sheep wool heat-insulating mattresses to simultaneously provide these needs, cumulatively analyzing efficiency indicators for thermal insulation and indicators of improving air quality. Thus, the values obtained for the coefficient of thermal conductivity, and its resistance to heat transfer, demonstrate the suitability of their use for thermal insulation. The results of the permeability to water vapor characteristics on the sorption/desorption of water, air, demonstrate the ability to control the humidity of the indoor air and the results on the reduction of the concentration of formaldehyde, demonstrating their contribution to the growth of the quality of the air, and to reduce the risk of disease in the population.

The Subject

Biodiversity knowledge is communicated by scientists to policymakers at the biodiversity “science-policy interface” (SPI). Although the biodiversity SPI is the subject of a growing body of literature, gaps in our understanding include the efficacy of mechanisms to bridge the interface, the quality of information exchanged between science and policy, and the inclusivity of stakeholders involved. To improve this understanding, we surveyed an important but under-studied group—biodiversity policymakers and scientific advisors representing their respective countries in negotiations of the Convention on Biological Diversity (CBD) and the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES). We found that a wide variety of SPI mechanisms were being used. Overall, they were considered to be sufficiently effective, improving over time, and supplied with information of adequate quality. Most respondents, however, agreed that key actors were still missing from the biodiversity SPI.

Classical Style

Although Europa 51 (1952) was the most commercially successful of the films Roberto Rossellini made with the Hollywood star, Ingrid Bergman, the reception by the Italian press was largely negative. Many critics focussed on what they saw to be the ‘unreal’ or abstract quality of the films portrayal of the postwar urban milieu and on the Bergman character‘s isolation from the social world. This article looks at how certain structures of seeing that are associated in the classical style with the woman as star or spectacle - e.g., the repetitious return to her fixed image, the resistance to pulling back from the figure of the woman in order to situate her within a determinate location and set of relationships between characters and objects - are no longer restricted to her image but in fact bleed into or “contaminate” the depiction of the world she inhabits. In other words, whereas the compulsive return to the fixed image of the woman tends to be contained or neutralised by the narrative economy and editing patterns (ordered by sexual difference) of the classical style, in Rossellini‘s work this ‘insistent’ even aberrant framing in relation to the woman becomes a part of the (female) characters and the cameras vision of the ‘pathology’ of the urban landscape in the aftermath of the war.
