Prolonged and repetitive COVID-19 facility closures have led to an abrupt cessation of visitors within UK and Irish zoos for variable periods since March 2020. This study sought to increase understanding of the impact of closures and reopenings on animal behaviour, thereby broadening understanding of whether zoo animals habituate to visitors. Data were collected from June to August 2020 at two UK facilities on eight species (n = 1 Chinese goral, n = 2 Grevy’s zebra, n = 11 swamp wallaby, n = 2 Rothschild’s giraffe, n = 2 nyala, n = 4 Chapman’s zebra, n = 2 snow leopard and n = 3 Amur leopard). Behaviour change and enclosure use was variable across species but most changes were non-significant. Grevy’s zebra engaged in more comfort behaviour during closure periods than post-closure (p < 0.05). Chinese goral engaged in more environmental interactions during closure periods (p < 0.05). Grevy’s zebra spent longer than would be expected by chance closest to public viewing areas during closure periods (p < 0.008). These results suggest variable impacts of covid-19 closures and reopenings, mirroring human-animal interaction literature. We highlight the potential for some species to take longer to re-habituate to the presence of zoo visitors. As facility closures/reopenings are ongoing, we advocate a longitudinal monitoring approach. Furthermore, we recommend incorporation of physical and physiological measures of welfare where possible, alongside behavioural responses, to enable a holistic approach to answering fundamental questions on whether zoo animals habituate to visitors.

The Impact

The coronavirus disease 2019 (COVID-19) pandemic presents an opportunity to explore the role of animals as sources of emotional and physical support during a period when most of the population is experiencing social and environmental challenges. We investigated how companion animal owners perceived the influence of human–animal interaction on their physical and mental health during the first COVID-19 lockdown phase in the U.K., and what concerns they had regarding their animals at this time. We also explored the impact of participants’ interaction with non-companion animals during this phase. A cross-sectional online survey of U.K. residents aged over 18 was conducted between April and June 2020. The final item of the survey invited open-ended free-text responses, allowing participants to describe any experiences and/or perceptions of their human–animal relationships during the COVID-19 lockdown phase. A qualitative thematic analysis of responses was undertaken. Four main themes related to the following aspects of human–animal interactions during the COVID-19 lockdown phase were identified: the positive impact of animal ownership during the COVID-19 lockdown (e.g., amelioration of wellbeing and mental health), concerns relating to animal ownership during the COVID-19 lockdown (e.g., concerns over animals carrying the COVID-19 virus), grief and loss of an animal during the COVID-19 lockdown and the impact of engaging with non-companion animals during the COVID-19 lockdown. The findings complement and extend previous insights into the impact of human–animal interaction with both companion and non-companion animals. They also highlight the challenges of caring for an animal during the lockdown phase and indicate the need to consider the development of further targeted support strategies, such as “day care” for the companion animals of key workers in this context.

Low Activity

Social isolation likely contributes to reduced welfare for shelter-living dogs. Several studies have established that time out of the kennel with a person can improve dogs’ behavior and reduce physiological measures of stress. This study assessed the effects of two-and-a-half-hour outings on the urinary cortisol levels and activity of dogs as they awaited adoption at four animal shelters. Dogs’ urine was collected before and after outings for cortisol:creatinine analysis, and accelerometer devices were used to measure dogs’ physical activity. In total, 164 dogs participated in this study, with 793 cortisol values and 3750 activity measures used in the statistical analyses. We found that dogs’ cortisol:creatinine ratios were significantly higher during the afternoon of the intervention but returned to pre-field trip levels the following day. Dogs’ minutes of low activity were significantly reduced, and high activity significantly increased during the outing. Although dogs’ cortisol and activity returned to baseline after the intervention, our findings suggest that short-term outings do not confer the same stress reduction benefits as previously shown with temporary fostering. Nevertheless, it is possible that these types of outing programs are beneficial to adoptions by increasing the visibility of dogs and should be further investigated to elucidate these effects.

To examine the impact of habitat heterogeneity on the bird communities, we investigated the structural differences of various bird communities occurring in heterogeneous habitats in the subtropical hilly areas of southern China. We used indicator Species Analysis (ISA) to test the association of specific bird species to particular habitats. We performed Two-way Cluster Analysis to find species patterning in response to habitat fragmentation. Our results demonstrated that heterogeneous habitats promoted bird diversity and human activities affected bird behavior. Indicator Species Analysis demonstrated that similar habitats had similar bird communities, while different habitats supported various bird indicator species. Although habitat diversity increased bird diversity of a region, it was unfavorable for the maintenance of specialized birds in the forests of the subtropical hilly area.

Water is indispensable to sustain life and livelihood, and rivers serve as major reservoirs of water in manyparts of the world. River Yamuna is the major tributary of the River Ganges in India and is considered to be among the most polluted rivers of the world. The Yamuna Action Plan (YAP) is one of the largest river restoration projects in India and is initiated to clean the river. YAP is a bilateral arrangement between the governments of India and Japan, and consists of three Actions Plans-I, II and III. YAP-III is currently under execution with some of the major projects being the construction of the new Wastewater Treatment Plant (WWTP) at Okhla, rehabilitation and upgrading of WWTPs at Kondli and Rithala in the Delhi region. The impact of YAP-III with regard to these major projects on the reduction of the pollutant load reaching the river and cost-benefit has been evaluated in the current study. Findings from the study indicated that major projects such as construction of a new WWTP at Okhla (124 MGD) can effectively reduce the pollutant load by 283 kg/MGD of wastewater at a cost of Rs. 1161 crores while the rehabilitation project at Rithala (Phase I) can reduce the pollutant load by 92.5 kg/MGD wastewater at a cost of Rs. 300 crores. The present study indicates the need to evaluate projects in terms of cost-benefit analysis in addition to the economic and environmental evaluation for effective action. A holistic approach towards treatment of pollutant load in the river and prevention of further pollutants from reaching the river is required in addition to community awareness and participation for sustainable river water management.

Legume Green Manure

To make a comparative study on the impact of green manure (legume, non legume and weed species) and inorganic fertilizer on crop yield and fertility status in soil an experiment was conducted for two successive years in shifting cultivation areas of Assam. Among the different green manure studied maximum yield of rice was recorded in legume green manure (1687.6 kg kgh-1) followed by inorganic fertilizer (1566.6 kgh-1) applied plot in initial year. However during successive year productivity was recorded low in fertilizer applied plot compared legume, non legume and weed green manure. Same trend was noticed in productivity of Maize also. Significant increase of nutrient uptake was observed in green manure treated plot. Fertilizer applied plot showed low value during successive year. Acidity of the soil increased due to release of organic acid during decomposition of green manure. Input of biomass to the soil contributed in increment of organic carbon, nitrogen and other mineral nutrients and thus maintaining productivity as well as fertility status in soil.

Bridge Bearings

Abstract Structural bearings of 47 offshore platform-link bridges with average age of 40 years were inspected and recommended for replacements due to their poor condition. Replacement of bridge bearings involves major risk and production interruptions given the structural modifications, and critical piping and E&I disconnections required for safe jacking-lifting activities required during the process. This paper presents the approach adopted to assure the integrity of the bridges and extend their lives without the need to replace the bearings. The approach employed failure mode and effect analysis to identifying and narrowing down areas that need focused efforts while tackling the problem. Scenario based structural assessments were carried out to examine the impact of the level of movement-allowing bearings functionality on the integrity of the bridge and its supporting structures; identify critical locations to be targeted during focused inspections; and establish envelopes for monitoring thermal expansion and contraction of the bridges. Guidelines were developed and implemented for integrated inspection-maintenance and repair campaign, which aimed to tackle corrosion issues and to install movement-monitoring indicators. Indicator seasonal monitoring is employed to establish the functionality of bearings on the long-term. The what-if structural assessments revealed that even in the worst-case scenario (in which the bearing are completely jammed) the option of local strengthening of the bridge and its supporting elements is more attractive than bearing replacement. The integrated inspection-maintenance and repair campaigns revealed that excessive corrosion levels observed from historic visual inspections on external non-critical bearing components (e.g: guide plates, angles, etc.) is not indicative of the condition of the internal load-bearing components (pedestals) which experienced much lower corrosion levels. The seasonal monitoring of bridge movements revealed that the 40+ years old Teflon pads are still functional and allow the bridges expansion and contraction. The developed holistic approach enabled demonstration of the fitness for service of the bearings, and provided means for assuring their long-term performance through monitoring. The results assured safety, integrity and delivered significant cost savings through aversion brownfield modifications, and production loss associated with bridge jacking and bearing replacement operations.

Abstract Hydraulic fracturing is a commonly used completion approach for extracting hydrocarbon resources from formations, particularly in those formations of very low permeability. As part of this process the use of Diagnostic Fracture Injection Tests (DFIT) can provide valuable information. When the measured pressures in such tests are outside the expected range for a given formation, a number of possibilities and questions will arise. Such considerations may include: What caused such inflated pressures? What is the in-situ stress state? Was there a mechanical or operational problem? Was the test procedure or the test equipment at fault? What else can explain the abnormal behaviour? While there may not be simple answers to all of these questions, such an experience can lead to a technically inaccurate conclusion based on inadequate analysis. A recently completed project faced just such a challenge, initially resulting in poor hydraulic fracturing efficiency and a requirement to understand the root causes. In support of this, a thorough analysis involving a multi-disciplinary review team from several technical areas, including petrophysics, rock/geo-mechanics, fluids testing/engineering, completions engineering, hydraulic fracture design and petroleum engineering, was undertaken. This paper describes the evolution of this study, the work performed, the results and conclusions from the analysis. The key factors involved in planning a successful DFIT are highlighted with a general template and a work process for future testing provided. The importance of appreciating the impact of the drilling and completion fluids composition, their properties and their compatibility with the formation fluids are addressed. The overall process and technical approach from this case study in tight gas fields, will have applicability across similar fields and the lessons learned could help unlock those reserves that are initially deemed technically or even commercially unattractive due to abnormal or unexpected behaviour measured during a DFIT operation.

Abstract Secondary air system seals are crucial in aero engine design as they have a direct impact on specific fuel consumption. Their behavior is affected by several aspects of the physics of the system: the air system, the engine thermal physics, the effect of flight loads and several other effects. As a consequence, their design is a complex and iterative process, which is highly dependent on the location of the seal in the engine, on the system requirements and on the system behavior. This paper describes a methodology for multi-disciplinary assessment of secondary air system seals within an engine environment and supports standard seal design, trade-off studies on novel concepts and system-level optimization. Defining the seal design intent for a specific engine location in the form of objectives, it is possible to embed process automation into traditionally manual multi-disciplinary design processes. This allows transforming modelling and simulation tools, which typically provide predictions for a specific seal design over reference cycles, into design and optimization tools, which can provide the optimum seal design for a specific set of requirements. This approach provides predictive models of both seal performance and performance degradation and is capable of taking into account all sources of variation, for instance manufacturing variations or engine operating conditions, delivering a robust design, specific to the engine location. The methodology enables a holistic approach to system and sub-system design and provides a deeper understanding of the impact of the seal onto system and of the system onto the seal, allowing optimization of the overall solution and informing the business case for introduction of different sealing strategies. Examples of the application of this methodology are provided for both labyrinth seals and leaf seals.

The Relationship

Purpose This study aims to explore the ways in which young people and prison staff (Prison Officers) within a youth custodial establishment experience empathy. Previous research tends to view empathy as a stable trait and one which people can develop through individual-centred therapy. There has been little consideration of the impact of relationship factors and context in relation to empathy experience and expression. The current study aims to address this by exploring the role of the custodial context in shaping empathy, including the potential impact of relationships, environmental factors and culture. Design/methodology/approach A qualitative approach was used to enable breadth and depth in the exploration of this area. Individual, semi-structured interviews were carried out with a purposive sample of three young people and three Prison Officers. Data was analysed using inductive thematic analysis informed by the guidelines of Braun and Clarke (2006) and King and Horrocks (2010). Findings Constructed themes included “constructions of empathy”, “recipe for empathy”, “institutional investment”, “the value of empathy” and “doing empathy”. Together, they provide detailed insight into the interplay of personal and wider contextual factors influencing the experience of empathy in a custodial setting. The findings suggest that the way in which young people and staff experience empathy in the custodial environment is unique. The findings suggest that empathy takes place within the context of relationships and is influenced by the nature of those relationships, along with the wider social context within which it occurs. Practical implications The findings of the current study support a move away from understanding empathy as an individual personality trait and instead viewing it as a dynamic experience that is changeable based upon the relationship and the context within which it occurs. The findings suggest that interventions aiming to develop empathy should look beyond the level of the individual and the relationship and focus upon developing environments that are supportive of empathy. Originality/value This study provides unique insights into the subjective experience of empathy in a custodial setting, presenting as one of the first to take a more holistic approach to understand this phenomenon.
