Abstract:

Environmental enrichment improves well-being of captive animals using a variety of tools, including adding complexity to the physical environment. Designing enrichment structures requires an understanding of behavioral and biological responses to enrichment efforts. Captive coyotes (Canis latrans) utilize shelter structures to hide, rest, and display vigilant behavior. Because these simple structures are regularly used, new and more complex enrichment structures could enhance enclosure enrichment. This study examined the time captive coyotes spent at discrete, complex enclosure features to det

Abstract:

Retractable spatial structures are modern buildings designed to comply with the user's flexibility needs – concerning the complete or partial opening of a building's enclosure. Most sport activities are usually preferred, by spectators as well as by competitors, to be held in open air. Swimming, a popular sport activity, is highly sensitive to cold and wind. The need for retractable structures arises since weather conditions vary with seasons while current market demand is for year-round activity. Designing retractable enclosures for swimming pools involves specific criteria, resulting from th

Abstract:

AbstractAn increasing number of zoos keep their animals in natural-looking enclosures, but it is often unclear whether or not the species’ behavioural and ecological needs are being adequately met. For species that suffer predation in the wild, structural enrichment in captivity can play a crucial role in connection with enclosure use. Firstly, we examined the effectiveness of structural enrichment in modifying enclosure use in an opportunistic carnivore, the red fox (Vulpes vulpes). In a test enclosure, we placed both long wooden and cover structures that simulated natural habitat in predeter

The effects of a transverse temperature gradient on the formation of regular and irregular acoustic streaming structures in air-filled, two-dimensional, rectangular, shallow enclosures carrying a longitudinal sound field are investigated numerically. The fluid motion is induced by the harmonic vibration of the enclosure left wall. The fully compressible form of the Navier—Stokes equations is considered to predict the primary oscillatory and secondary pseudo-steady streaming flow fields. An explicit time-marching flux-corrected transport algorithm is used to simulate the acoustic wave formation

Recent research has led to a re-evaluation of the defensive role formerly assigned to the Late Neolithic enclosures of western France.

Human remains in the enclosure ditches underline their significance as symbolic as well as physical boundaries.

Abstract:

(Uploaded by Plazi for the Bat Literature Project) Understanding the behavior of wildlife in zoo environments is necessary to determine species' welfare states and minimize stress whilst optimizing social groupings, particularly where breeding programs are being undertaken. This observational study investigated the behavior and welfare of six groupings of ghost bats (Macroderma gigas) across the breeding and post-breeding seasons within Perth Zoo, Western Australia. Scan sampling was used to record behavioral states and interactions along with spatial preferences within enclosures for 198 hour

Abstract:

For modern urban construction in the compacted conditions of new sites, the question of the stability of soil massifs under existing buildings is relevant. The intensity of development of possible deformations largely depends on the mutual location of the base of the previously erected foundation and the pit for the new building. The article provides a methodology for determining the area of influence of the pit on the soil foundations of adjacent buildings, depending on the type of enclosing structures and the depth of the pit used. The impact zone was calculated for the pit using protective

As a result of the work carried out, four fences were excavated at the burial ground: No. 9, 13, 29, 50. The burial, located in enclosure No. 9, was made in a dirt pit with a dromos designed in the form of a tambour, which obliquely enters the eastern wall of the grave pit u

Abstract:

Remnant field systems and enclosures are key indicators of social change during the 2nd millennium bc – their study has considerable significance in terms of interpreting the Bronze Age in the eastern region. Despite widespread current interest in the topic, little if any evidence for Middle Bronze Age settlement and land division had been found in Norfolk prior to the investigations at Ormesby St Michael which form the focus of this paper. Here, archaeological excavations uncovered evidence for strip field systems, succeeded by a large and well dated enclosure containing at least two structur

The airflow structure of enclosure directly affects the spread of COVID-19 and is also closely related to indoor air quality, thermal comfort of personnel, and building energy consumption. Although a large number of studies on the airflow field have been conducted under mixing and displacement ventilation with a single air inlet in rectangular rooms. However, to the best of the authors knowledge, only a limited number of studies have dealt with airflow structures in a multi-slot ventilation enclosure with opposed jets.

Abstract:

A 2.5 ha open area excavation at South Hornchurch, Essex (London Borough of Havering) has revealed an extensive Late Bronze Age settlement on the Thames terrace gravels. The site is particularly significant because of the association of a circular ditched enclosure or ringwork with a contemporary field system, as well as clusters of enclosed and unenclosed circular structures. Two enclosures were formed by rings of pits or large post-holes. Placed pottery deposits and unurned cremation burials were found, mostly associated with structures and entranceways. Other finds include both plain and de

Abstract Most previous studies of Early Woodland ritual and ceremonialism in the Ohio region have focused primarily on Adena mound and earthwork enclosures and their attendant mortuary facilities. Recent investigations of other constructions, such as circular post structures, have demonstrated the feasibility of expanding interpretations of Early Woodland ceremonialism to include nonmortuary contexts. In the southern drainages of Lake Erie, small hilltop enclosures are potentially fruitful localities for the study of (non-Adena) ritual and ceremonialism. Recent investigations at the Heckelman

Abstract:

In modern realities, the construction of multi-story buildings increasingly has to be carried out in the conditions of dense urban development. Since high-rise buildings are characterized by the presence of deep pits, there is a need to select the parameters of the enclosing structures (retaining walls) and take into account the influence of the pit arrangement and enclosing structures on the existing building. Numerical simulation of the stress-strain state (SSS) of the elements "soil base - existing structures - pit enclosure" was performed to assess the impact of choosing the dimensions of

Vibration of structures due to external sound is one of the main causes of interior noise in cavities like automobile, aircraft, and rotorcraft, which disturb the comfort of passengers. Accurate modelling of such phenomena is required in eigenfrequency analysis and in designing an active noise control system to reduce the interior noise. In this paper, the effect of periodic noise travelling into a rectangular enclosure is investigated with finite element method (FEM) using COMSOL Multiphysics software. The periodic acoustic wave is generated by a point source outside the enclosure and propaga

Ecological floating beds are effective in mitigating lake eutrophication.

The results revealed that among basic carbon sources, only the δ13C values of phytoplankton and POM differed significantly, while most consumers showed no significant differences in carbon and nitrogen stable isotope characteristics across the three r

The ground surface deformation induced by shield tunnels passing through enclosure structures of existing tunnels is a particular underground construction scenario that has been encountered in Wuhan Metro Line 12 engineering cases in China.

This paper develops a semi-analytical method to predict ground heave considering the space effect in this engineering condition. Based on the improved ground deformati
