AbstractThe Chongwen Pagoda is the tallest masonry pagoda in China, with numerous openings inside the pagoda body. It is prone to damage during earthquakes, and the patterns of damage are complex. In order to scientifically analyze the dynamic performance, earthquake damage patterns, and mechanisms of the pagoda structure, on‐site dynamic testing was conducted to obtain the dynamic characteristics of the structure. A numerical model was established using Abaqus finite element software to calculate the dynamic characteristics of the structure. The results were compared with the testing results and showed a close agreement. El‐Centro earthquake wave, Taft earthquake wave, and Lanzhou artificial earthquake wave were selected as earthquake inputs based on site conditions, simulating frequent earthquakes, fortification earthquakes, and rare earthquakes with a magnitude of 9. The dynamic response of the pagoda structure was calculated, and the relationship between acceleration amplification factor, interstorey displacement, and interstorey displacement angle with floor height was analyzed. The seismic damage to the structure and the distribution of primary tensile stresses were studied, revealing the seismic damage mechanisms and the distribution characteristics of vulnerable areas in the Chongwen Pagoda. The research results provide references for the seismic assessment of this ancient pagoda.

AbstractAdrenalectomy is the gold standard for canine adrenal tumours, but not always recommended due to patient age, underlying conditions and perioperative mortality. Ethanol ablation is an alternative in human medicine for poor surgical candidates. A 13‐year‐old neutered female toy‐poodle with hypercortisolism presented with severe haematuria. Ultrasonography revealed left adrenal and right kidney tumours. Due to high surgical risk, simultaneous laparotomic right nephroureterectomy and ethanol ablation of the left adrenal tumour were performed. Post‐ethanol injection complications included transient hypertension and arrhythmia, which resolved spontaneously. The adrenal tumour size decreased within 2.5 months, and cortisol levels normalised within 8 days, remaining stable for 12 months. No hypercortisolism signs were observed without trilostane until death from renal insufficiency. Autopsy showed that the ablated left adrenal gland was an adrenocortical tumour and had shrunk. Ethanol ablation may be a feasible alternative to adrenalectomy for high‐risk canine patients.
Family flock size and age–sex structure of indigenous village chickens
Authors: Desta Takele Taye , Wakeyo Oli 
Published: September 2024

AbstractBackgroundIndigenous village chickens (IVCs) significantly contribute to rural development. There is considerable variation in family flock size and age–sex structure of IVCs.ObjectivesThis study reports the family flock size, age–sex group structure, and demographic history of IVCs.MethodsThis work involved a cross‐sectional study conducted using face‐to‐face general informants’ individual interviews with 119 smallholder farmers in highland and lowland agroecological zones.ResultsThe average family flock size of the sampled households was small (mean = 7.28, range: 1–38). Female birds (hens and pullets) represented the largest proportion of the family flocks (50.2%). The proportion of chicks (26.4%) and pullets (14.4%) was lower than that of hens (35.8%), which creates a considerable challenge in producing replacement breeding flocks. Similarly, the proportion of cockerels (9.1%) was lower than that of cocks (14.3%). The average cock‐to‐hen ratio (one cock to seven hens) was better than the commonly recommended proportion (1 cock to 8–10 hens). As a result, smallholder farmers have not faced the problem of producing infertile eggs. The estimated effective population size (Ne) of 4.02 and the corresponding inbreeding coefficient of 0.12 at the family flock level show that to some extent inbreeding may occur at the family flock level; besides, the estimated Ne represents 55.2% of the census size. However, inbreeding could be offset by the high rate of flock turnover and uncontrolled mating among scavenging birds.ConclusionsFamily flocks contain a few birds, which may lead to consanguineous mating. Inbreeding is, however, considerably reduced by uncontrolled breeding among birds that share a common scavenging ground. The driving factors behind the low proportion of chicks and juvenile birds and the family flock size need to be further investigated to improve the contribution of local chickens to rural livelihoods.

AbstractBackgroundTicks are vectors of pathogens that affect the health of animals and humans. With the constant trade of livestock across borders, there is the risk of new tick species invasion accompanied by the spread of infectious tick‐borne pathogens.AimThis study sought to determine the diversity of tick species within abattoirs and a slaughter slab as well as identify the pathogens carried by these ticks.MethodsThe ticks were collected from slaughtered cattle, identified and screened for pathogens using PCR and sequencing.ResultsA total of 371 ticks were collected from slaughtered cattle across the three sampling sites: Kumasi abattoir (288, 77.63%), Akwatia Line slaughter slab (52, 14.02%) and Suame abattoir (31, 8.35%). The predominant species was Amblyomma variegatum (85.44%) with Rhipicephalus sanguineus (s.l.) (0.27%) as the least occurring species. Total nucleic acid from the tick pools was screened for pathogens based on the nucleoprotein gene region in the S segment of the Crimean–Congo haemorrhagic fever virus (CCHFV) genome, the 295‐bp fragment of the transposase gene of the Coxiella burnetii IS1111a element, the 560 bp segment of the ssrRNA gene of Babesia and Theileria, the 345 bp fragment of the Ehrlichia genus 16SrRNA gene and the rOmpA gene (OmpA) of Rickettsia. From the 52 tick pools screened, 40 (76.92%) were found positive for pathogen DNA. The pathogens identified were Rickettsia africae (69.23%), Rickettsia aeschlimannii (7.69%), C. burnetii (5.77%), uncultured Ehrlichia sp. (5.77%), Candidatus Midichloria mitochondrii (3.85%) and CCHFV (3.85%). A significant association was observed among A. variegatum, Hyalomma rufipes, Hyalomma truncatum and occurring tick‐borne pathogens R. africae, R. aeschlimannii and uncultured Ehrlichia sp. (p < 0.001).ConclusionThe findings show the occurrence of zoonotic pathogens, suggesting an increased risk of infections among the abattoir workers. There is a need to adopt control measures within the abattoirs to prevent pathogen spread.

AbstractBackgroundWith the ban on the use of antibiotics in poultry nutrition, the opinion of nutritionists turned to their alternatives. Garlic and mushroom are the two important phytobiotic compounds in poultry nutrition.ObjectivesThis experiment was done to investigate the effect of garlic powder (GP) and mushroom powder (MP) on the growth performance, meat quality, serum lipid profile, and intestinal morphology of broilers.MethodsFive hundred and seventy‐six one‐day‐old male Ross 308 broiler chicks were assigned to eight treatments with six replications based on a completely randomized design in a factorial arrangement of 4*2 with four levels of GP (0.00, 0.50, 1.00, 1.50%) and two levels of MP (0.00, 1.00%).ResultsNo significant effects of GP and MP on the performance were observed. With increasing levels of GP in the diets, the lightness and redness of breast meat decreased and increased, respectively (p < 0.05). The effect of increasing the amount of GP on the reduction of total cholesterol level was similar in the absence or presence of MP. With increasing levels of GP in the diets, the villus height (VH) and VH to crypt depth ratio (VH: CD) increased. The use of MP in the diets significantly increased VH and VH: CD (p < 0.05).ConclusionThe addition of GP and MP to the broilers’ diets did not have any negative effect on the performance. These pharmaceutic herbs improved intestinal morphology. In addition, increasing the level of GP amended the meat color and reduced the level of serum cholesterol.

AbstractA 10‐year‐old, male, farm‐based springer spaniel that presented with subacute progressive left‐sided central vestibular signs was diagnosed with meningoencephalitis of unknown origin. The patient received prednisolone (2 mg/kg/day orally), ciclosporin (5 mg/kg orally twice a day) and a single infusion of cytarabine (200 mg/m2). Six weeks later, neurological signs had resolved, but multiple cutaneous nodules developed on the limbs, trunk and face. Lesions discharged a dark purulent material without tissue grains. A ‘filamentous fungus’ was isolated, but discarded without identification. Aspirates from nodules showed pigmented, septate fungal hyphae, and culture of aspirates yielded Trematosphaeria grisea. Itraconazole (5 mg/kg once a day) and gradual tapering of immunosuppressive drugs led to resolution of nodular lesions over 4 months without neurological relapse. A fungal granuloma developed transiently 8 months after starting itraconazole. Immunosuppressive drugs were stopped 15 months after introduction without neurological relapse. Itraconazole was withdrawn 8 weeks later, 5 months after last relapse of skin disease.

AbstractWe present a case of a 3‐year‐old, male Border Collie with severe hip dysplasia and osteoarthritis undergoing total hip replacement, notably having a history of a previous hip surgery with inadequate epidural analgesia. Our objective was to evaluate epidural efficacy before surgery using nociceptive threshold measurement. Nociceptive thresholds were measured with transdermal electrical stimulation via the Dolosys Pain Tracker device. The dog received epidural ropivacaine and morphine, resulting in a cessation of withdrawal response and electromyographic activity. This effect was confirmed under anaesthesia. Postoperatively, the dog recovered without relevant complications. In conclusion, nociceptive threshold measurement using the Dolosys Pain Tracker device allowed immediate confirmation of epidural efficacy, reducing the risk of intraoperative analgesic inadequacy. This approach may enhance surgical pain management in challenging cases.
Trends in Reptile Holdings Across UK Zoos: Identification of the Factors Responsible for Declining Numbers of Venomous Snake

Published: September 2024

ABSTRACTZoos are under increasing pressure to strategically manage their collections to maximize visitor attendance, financial income, and their contribution to conservation. As a result, the compositions of zoo collections are undergoing significant changes. Many zoos are keeping fewer species and prioritizing keeping large flagship animals that are more attractive to the public. To understand the effects these changes are having on captive reptile numbers, we have analyzed the trends in reptile holdings between 2003 and 2023 at UK zoos. Our findings show that despite an overall increase in reptile numbers in the period analyzed, there has been a dramatic decline in the number of venomous snakes held at UK zoos, and as a result, venomous snakes are being excluded from many of the conservation benefits that zoos provide. To understand the key factors contributing to the decline in venomous snake numbers, 57 staff members across 35 different BIAZA–accredited zoos were surveyed. Results from the survey identified that a perceived increased risk of harm, increasingly stringent health and safety regulations, and increased husbandry requirements were all key contributing factors to why venomous snake numbers at zoos are in decline.

AbstractA Ground Level Enhancement (GLE) event can be observed as an increase in the background of ground‐based neutron monitor observations and is often associated with an increase of >500 MeV space‐based proton flux measurements. GLE events begin as very high‐energy SEP events associated with GeV protons. For such events to be detected at sea level, proton energies must exceed about 433 MeV. Since the increased flux of such particles can be a major problem to technology in space and on Earth and pose a threat for human health, developing real time warning systems is of great importance. GLE Alert++ is a product, built by the Athens Cosmic Ray Group of the National and Kapodistrian University of Athens, that issues alerts when a GLE event starts to register and is based on ground‐based neutron monitor observations. From the space‐based approach, the HESPERIA UMASEP‐500 product, jointly developed within the framework of the EU HORIZON2020 HESPERIA project by the Universidad de Malaga, Spain and National Observatory of Athens, Greece, provides forecasts of GLE events and >500 MeV protons relying on GOES satellite Soft X‐Ray and high energy proton observations. These two products are fully integrated as federated products on the ESA SWE Portal and are provided as part of the ESA Space Safety Program Space Weather Service Network. In this paper we present how the products were built, provide examples of their outputs as seen on the ESA SWE Portal, and show how the products complement each other and how using them together can in some instances provide more information for users of these services.

AbstractIn this study, we evaluate mesoscale convective system (MCS) simulations in the second version of U.S. Department of Energy (DOE) Energy Exascale Earth System Model (E3SMv2). E3SMv2 atmosphere model (EAMv2) is run at the uniform 0.25° horizontal resolution. We track MCSs consistently in the model and observations using PyFLEXTRKR algorithm, which defines MCSs based on both cloud top brightness temperature (Tb) and surface precipitation. Results from using only Tb to define MCSs are also discussed to understand the impact of different MCS tracking algorithms on MCS evaluation and provide additional insights into model errors in simulating MCSs. Our results show that EAMv2 simulated MCS precipitation is largely underestimated in tropical and extratropical regions. This is mainly attributed to the underestimated MCS genesis and underestimated precipitation intensity in EAMv2. Comparing the two MCS tracking methods, simulated MCS precipitation is increased if MCSs are defined with only cloud top Tb. The Tb‐based MCS tracking method, however, includes cloud systems with very weak precipitation. This illustrates the model issues in simulating heavy precipitation even though the convective cloud shield is overall well simulated from the moist convective processes. Furthermore, sensitivity experiments are performed to examine the impact of new cloud and convection parameterizations developed for EAMv3 on simulated MCSs. The new physics parameterizations help increase the relative contribution of convective precipitation to total precipitation in the tropics, but the simulated MCS properties are not significantly improved. This suggests that simulating MCSs still remain a challenge for the next version of E3SM.

Published: September 2024

AbstractMarine cold‐air outbreaks, or CAOs, are airmass transformations whereby relatively cold boundary layer (BL) air is transported over relatively warm water. To more deeply understand BL and mixed‐phase cloud properties during CAO conditions, the Cold‐Air Outbreaks in the Marine Boundary Layer Experiment (COMBLE) took place from late 2019 into early 2020. During COMBLE, the U.S. Department of Energy's first Atmospheric Radiation Measurement Mobile Facility (AMF1) was deployed to Andenes, Norway, far downstream (∼1,000 km) from the Arctic pack ice. This study examines the two most intense CAOs sampled at the AMF1 site. The observed BL structures are open cellular with high (∼3–5 km) and cold (−30 to −50 C) cloud tops, and they often have pockets of high liquid water paths (LWPs; up to ∼1,000 g ) associated with strong updrafts and enhanced turbulence. We use a high‐resolution mesoscale model to explore how well four turbulence closure methods represent open cellular clouds. After applying a radar simulator to model outputs for direct evaluation, cloud top properties agree well with AMF1 observations (within ∼10%), but radar reflectivity and LWP agreement is more variable. Results suggest that the turbulent Prandtl number may play an important role for the simulated BL and cloud properties. All simulations produce enhanced precipitation rates that are well‐correlated with a cloud transition. Finally, the eddy‐diffusivity/mass‐flux approach produces the deepest cloud layer and therefore the largest and most coherent cellular structures. We recommend the use of a non‐local turbulence closure approach to better capture turbulent processes in intense CAOs.

Published: September 2024

AbstractIn light of the increasing hydrogen permeability in distribution networks as a means to cope with extreme events and improve network resilience, this paper introduces a novel strategy for enhancing power distribution network resilience. It outlines a comprehensive approach that focuses on dispatching hydrogen storage (HS) and hydrogen vehicle (HV) within hydrogen penetrated distribution systems (HPDS), segmenting the strategy into pre‐disaster and post‐disaster stages. Firstly, in the pre‐disaster stage, models for HS and HVs are established to gather operational data and facilitate rapid post‐disaster response, alongside a coupled electric grid and road network model for optimising HV routing and dispatch. Subsequently, the post‐disaster stage focuses on a scheduling model that aims to minimise load power losses and economic costs, balancing immediate power support with cost‐effectiveness through detailed analysis of HS and HV dispatch strategies. Finally, this paper demonstrates the effectiveness of this strategy via a case study, highlighting significant improvements in network resilience and recovery and underscoring the potential of hydrogen technologies in enhancing infrastructure resilience.

Published: September 2024

AbstractMultiple port DC/DC converters have applications in many fields: hybrid energy storage systems where batteries are combined with supercapacitors, multi‐level and multi‐modular inverters that need multiple DC sources, and DC microgrids. Among these converters, the Multiple Active Bridge (MAB) is particularly attractive due to its high power ratings and galvanic isolation capabilities. This paper introduces an advanced dual‐duty modulation technique for MAB converters designed to significantly reduce conduction losses over a wide range of input voltages by minimizing the harmonics’ reactive power on the AC stage. Consequently, it can improve the converter's efficiency when dealing with non‐constant voltage sources such as batteries and supercapacitors. The overall control technique is based on the dq‐frame control method under the first harmonic approach (FHA). This method is verified through simulations and implemented in a 1000 W triple‐port prototype. In the simulation, conductive and switching losses are modelled, and the trade‐off between these loss types is discussed. The experimental results affirm an overall improvement in efficiency for certain scenarios involving non‐unit voltage conversion ratios.

AbstractThis paper investigates the deployment of solar technology throughout an electric railway system to accommodate tractive power needs. The approach is evaluated from both a technical and financial standpoint to better understand its overall feasibility. A case study is presented using New York City's subway system as the centre of deployment. As a means to both prevent excess voltages, as well as contribute to the city's shift to zero emission, parallel electric bus charging is also studied. It has been demonstrated that the proposed integration allows the subway system to still function without any hindrance to rail operation. The system is able to provide charging power for three to six electric buses per passenger station. In addition, the approach shows long‐term financial growth with average annual electric bill savings of approximately $50,000 per passenger station, each with a relatively short payback period of approximately 4 years.
