Bangladesh, is concerned about the risk of Mpox elaborately, monkeypox as a worldwide health emergencies, especially after the arrival of the rapid spreading Clade 1b strain in India. Bangladesh has not yet reported any instances, but there is a high danger of transmission due to huge population density and close border to India. The interim administration is urged in this letter to take proactive steps, such as disease surveillance, cross-border collaboration, and preparedness of healthcare infrastructure. Bangladesh has to improve its readiness in order to stop another breakout and lessen the possible social and economic effects, taking inspiration from the COVID-19 pandemic.
A separate approach of sustainable development is to make the structures durable. More durable structures need to be replaced less frequently and will reduce the need for cement. Such increase in durability can be achieved by choosing appropriate mix designs and selecting suitable aggregates and admixtures. In this experiment sand (fine aggregate) is partially replaced by stone dust to make the concrete mix sustainable in nature. This study also investigates the durability of different types of concrete in acid exposure. Cube compressive strengths of different mixes have been compared to see how the concrete strength differs from original mixes. In addition different types of non-destructive tests such as ultrasonic pulse velocity test, rebound hammer test and half-cell potential tests have also been performed on the concrete samples for better analysis of their strength and durability characteristics. Specimens were analysed through the Scanning Electron Microscope to understand the microstructural changes of concrete samples. Energy dispersion X-ray analysis was also done to understand the changes in the nature of the hydration products of some specimen.
Feline Infectious Peritonitis (FIP), caused by Feline Coronavirus (FCoV), is a fatal disease affecting domestic and feral cats worldwide. This study aimed to determine the prevalence, risk factors, and clinical manifestations of FIP and to analyse treatment protocols employed at the Central Veterinary Hospital (CVH), Dhaka, Bangladesh. A total of 305 feline cases were examined during a five-month period (December 2023–May 2024), revealing an FIP prevalence rate of 12.13%. Key risk factors included age, sex, breed, and vaccination status. Cats aged 11–20 months and >31 months, males, non-vaccinated, and certain breeds such as British Shorthair and Bengal cats demonstrated higher susceptibility. Clinical manifestations predominantly included ascites (100%) and respiratory distress (81.09%), with fever (67.56%) and mild dehydration (86.48%) also observed. The effusive form of FIP was more prevalent, characterized by fluid accumulation in body cavities. Diagnostic confirmation utilized rapid diagnostic test kits and Rivalta’s test, with a combination of both tests achieving the highest accuracy. This study underscores the critical need for early diagnosis, vaccination programs, and breed-specific prevention strategies to reduce the impact of FIP. Enhanced diagnostic tools. These findings provide valuable insights into the clinical management of FIP in the feline population in Dhaka, contributing to global efforts in understanding and mitigating this devastating disease.
The enormous production of Ordinary Portland Cement is causing hazards to environment as well as reduction in natural sources though it is versatile materials and most important constituent of concrete.Due to this warning to ecosystem the researchers are directed to use industrial by products as supplementary cementitious material in usual manner in the present days in making concrete. In the experimentations, the silica fume is used as industrial by-product in normal concrete thereby increasing the mix design variables for which the mix proportioning is manysided. The prime intention of this paper is to investigate the various mechanical properties essentially on workability and strength. Compressive strength, Slump and Compacting factor tests of silica fume concrete are performed for strength and workability respectively. For this paper 15 (five) mixes of silica fume concrete are cast for experiments. Various cement replacement levels by silica fume for three water-cementitious material ratios of 0.40, 0.45 and 0.50 are used in experiments whereas other mix design parameters are kept unvarying. The cement replacement levels by silica fume are 0%, 5%, 10%, 15% and 20% for three water-cementitious materials (w/cm) ratio of 0.40, 0.45 and 0.50. Compressive strengths, compacting factors and slumps are evaluated at different age levels like at 24 hours, 7 and 28 days for both 100 and 150 mm cubes.
Tri-μ-chloro-chloropentakis(dimethyl sulfoxide)diruthenium (II), [Ru 2 Cl{(CH 3 ) 2 SO} 5 (μ-Cl) 3 ] has a face-sharing bioctahedral structure with the common face constructed by three bridgin Cl atoms. The metal atoms are separated by 3.245 (2) A
Background: Bronchiectasis, a progressive chronic respiratory disease referring to abnormal and permanent bronchial dilatation, have clinical characteristics that may vary geographically, pointing out the importance of national registries. However, there is a lack of data about the characteristics of Swedish patients with bronchiectasis. Aim: To describe the first cohort of Swedish patients with bronchiectasis followed in a tertiary centre. Methods: Karolinska University Hospital is a part of the European Multicenter Bronchiectasis Audit and Research Collaboration (EMBARC). We have recruited patients with bronchiectasis in our outpatient clinic using EMBARC methodology and protocol. Results: The first 70 patients were recruited; median age 68 years (range 19-90), 68.6% females, 52.9% were ex-smokers, and 8.6 % were underweight (BMI< 18.5). The main aetiology was post-infective (61.4%). Most (54.3 %) showed airway flow limitation (FEV1 < 80% predicted), while 18.6 % reported dyspnoea (mMRC ≥2). Most patients had mucoid sputum (75%) followed by mucopurulent (17.6%) and purulent (7.4%). Pseudomonas aeruginosa (33.3%) and Haemophilus influenzae (24.2%) were mainly isolated among patients (33/65) with a positive sputum culture. Patients with Pseudomonas had significantly increased sputum production than those without organisms (p< 0.01). Conclusions: This first report from the Swedish EMBARC cohort describes bronchiectasis patients with characteristics seen earlier in national cohorts from and outside Europe, justifying the value of the EMBARC registry and the establishment of the Swedish registry.
