    The feeding habits of mona monkey Cercopithecus mona in Ayede/Isan forest reserve, Ayede, Ekiti State, Nigeria were studied for six months. Direct observation was used in the data collection. The study area was visited two days per week between 0600-1100hours and 1600-1800hours for the six months in the forest reserve stretching from dry season to wet season. Data collected on the plant species and the parts of the plant species the animal feed upon revealed that mona monkey feeds on wide varieties of plant species and the parts of the plant consumed most is the fruits. It was noted that mona monkey is a social animal that moves and feeds in group. The mona monkey feeds mainly on fresh leaves, fruits and seeds of different plant species. Some of the plant species preferred by the mona monkey include: oil palm tree Elaeis guineesis, bitter mango Irvingia grandiforiola, kola Cola nitida. Most of the plant food materials the monkey feed upon are seasonal while some such as palm tree Elaeis guineesis are available for the animal to feed on throughout the year

    The Past Has Ears (PHE): XR Explorations of Acoustic Spaces as Cultural Heritage

    Get PDF
    Hearing is one of our most pervasive senses. There is no equivalent to closing our eyes, or averting our gaze, for the ears. When we think about great architectural achievements in European history, such as ancient amphitheatres or Gothic cathedrals, their importance is strongly tied to their acoustic environment. The acoustics of a heritage site is an intangible consequence of the space's tangible construction and furnishings. Inspired by the project's namesake (Phe, for the constellation Phoenix), and the relatively recent res at Cathedrale de Notre Dame de Paris and Teatro La Fenice opera hall, the PHE project focuses on virtual reconstruction of heritage sites, bringing them back from the ashes. In addressing the intangible acoustic heritage of architectural sites, three main objectives have been identied for this research project: Documentation, Modelling, and Presentation. In parallel, three heritage sites are participating as case studies: Tindari Theatre (IT), Notre-Dame de Paris Cathedral (FR), and The Houses of Parliament (UK). The acoustics of a space is immersive, spatial, and due to the nature of auditory perception egocentric, in contrast to visual perception of an object, which can be observed from outside". Consequently, presentation methods for communicating acoustic heritage must represent the spatially immersive and listener-centric nature of acoustics. PHE will lead development of a museum grade hardware/software prototype for the presentation of immersive audio experiences adaptable to multiple platforms, from on-site immersive speaker installations, to mobile XR via smartphone applications

    Mortality in over 350,000 Insured Swedish dogs from 1995–2000: I. Breed-, Gender-, Age- and Cause-specific Rates

    Get PDF
    This study presents data on over 350,000 insured Swedish dogs up to 10 years of age contributing to over one million dog-years at risk (DYAR) during 1995–2000. A total of 43,172 dogs died or were euthanised and of these 72% had a claim with a diagnosis for the cause of death. The overall total mortality was 393 deaths per 10,000 DYAR. Mortality rates are calculated for the 10 most common breeds, 10 breeds with high mortality and a group including all other breeds, crudely and for general causes of death. Proportional mortality is presented for several classifications. Five general causes accounted for 62% of the deaths with a diagnosis (i.e. tumour (18%), trauma (17%), locomotor (13%), heart (8%) and neurological (6%)). Mortality rates for the five most common diagnoses within the general causes of death are presented. These detailed statistics on mortality can be used in breed-specific strategies as well as for general health promotion programs. Further details on survival and relative risk by breed and age are presented in the companion paper [14]

    Mortality in over 350,000 Insured Swedish Dogs from 1995–2000: II. Breed-Specific Age and Survival Patterns and Relative Risk for Causes of Death

    Get PDF
    This study continues analysis from a companion paper on over 350,000 insured Swedish dogs up to 10 years of age contributing to more than one million dog-years at risk during 1995–2000. The age patterns for total and diagnostic mortality and for general causes of death (trauma, tumour, locomotor, heart and neurological) are presented for numerous breeds. Survival estimates at five, eight and 10 years of age are calculated. Survival to 10 years of age was 75% or more in Labrador and golden retrievers, miniature and toy poodles and miniature dachshunds and lowest in Irish wolfhounds (91% dead by 10 years). Multivariable analysis was used to estimate the relative risk for general and more specific causes of death between breeds accounting for gender and age effects, including two-way interactions. Older females had tumour as a designated cause of death more often than males in most breeds, but not in the Bernese mountain dog. Information presented in this and the companion paper inform our understanding of the population level burden of disease, and support decision-making at the population and individual level about health promotion efforts and treatment and prognosis of disease events

    Prospective of biodiesel production utilizing microalgae as the cell factories: A comprehensive discussion

    Get PDF
    Microalgae are sunlight-driven miniature factories that convert atmospheric CO2 to polar and neutral lipids which after esterification can be utilized as an alternative source of petroleum. Further, other metabolic products such as bioethanol and biohydrogen produced by algal cells are also being considered for the same purpose. Microaglae are more efficient than the conventional oleaginous plants in capturing solar energy as they have simpler cellular organization and high capacity to produce lipids even under nutritionally challenged and high salt concentrations. Commercially, microalgae are cultivated either in open pond systems or in closed photobioreactors. The photobioreactor systems including tubular bioreactors, plate reactors and bubble column reactors have their own advantages as they provide sterile conditions for growing algal biomass. Besides, other culture conditions such as light intensity, CO2 concentration, nutritional balance, etc, in closed reactors remain controlled. On the other hand, though the open ponds provide a cost-effective option to utilize natural light facility for algal cells, the tough maintenance of optimal and stable growth conditions makes it difficult to manage the economy of the process. Further, these systems are much more susceptible to contamination with unwanted microalgae and fungi, bacteria and protozoa that feed on algae. Recently, some work has been done to improve lipid production from algal biomass by implementing in silico and in vitro biochemical, genetic and metabolic engineering approaches. This article represents a comprehensive discussion about the potential of microalgae for the production of valuable lipid compounds that can be further used for biodiesel production

    Numerical Simulation of Flow Past a Prolate Spheroid

    The prolate spheroid is geometrically very simple but the flow characteristics are complex which are dominated by transition and three-dimensional separation phenomenon having both primary and secondary vortex. The transition phenomenon in this flow is triggered due to the stream wise Tollmien-Schlichting (T-S) wake instability and cross flow instability, which makes the prediction more challenging due to lack of effective predictive tool to model transition. The present work aims at simulating numerically the three-dimensional turbulent flow past 6:1 prolate spheroid at Re=4.2 x 106 using RANS approach for which experimental data are available in literature. These simulations have been carried out using parallel version of the in-house multiblock structured incompressible flow solution code 3D-PURLES (3D Pressure based Unsteady Reynolds Average Navier Stokes and LES solver)

    <p>Abstract</p> <p>Background</p> <p>Pancreaticoduodenectomy is the procedure of choice for tumors of the head of the pancreas and periampulla. Despite advances in surgical technique and postoperative care, the procedure continues to carry a high morbidity rate. One of the most common morbidities is delayed gastric emptying with rates of 15%–40%. Following two prolonged cases of delayed gastric emptying, we altered our reconstruction to avoid this complication altogether. Subsequently, our patients underwent a classic pancreaticoduodenectomy with an undivided <it>Roux-en-Y </it>technique for reconstruction.</p> <p>Methods</p> <p>We reviewed the charts of our last 13 Whipple procedures evaluating them for complications, specifically delayed gastric emptying. We compared the outcomes of those patients to a control group of 15 patients who underwent the Whipple procedure with standard reconstruction.</p> <p>Results</p> <p>No instances of delayed gastric emptying occurred in patients who underwent an undivided <it>Roux-en-Y </it>technique for reconstruction. There was 1 wound infection (8%), 1 instance of pneumonia (8%), and 1 instance of bleeding from the gastrojejunal staple line (8%). There was no operative mortality.</p> <p>Conclusion</p> <p>Use of the undivided <it>Roux-en-Y </it>technique for reconstruction following the Whipple procedure may decrease the incidence of delayed gastric emptying. In addition, it has the added benefit of eliminating bile reflux gastritis. Future randomized control trials are recommended to further evaluate the efficacy of the procedure.</p
